  Embodiments of the present invention will be described below with reference to the drawings. In addition, in each figure, the same code | symbol is attached | subjected to the mutually same or equivalent member, and the overlapping description is abbreviate | omitted.

  FIG. 1 is a diagram showing a configuration of a panel assembly 100 as a movable partition according to the first embodiment of the present invention. (A) is a partial exploded perspective view, (b) is a horizontal partial sectional view, (c) is a vertical partial sectional view, (d) is a partial detailed sectional view including a second filler 140 described later, and (e) is a sectional view. FIG. 4 is a partial detailed cross-sectional view including a first filler 130 described later, and FIG. 5F is a partial detailed cross-sectional view including a third filler 150 described later.

  The panel assembly 100 typically divides the space, and is disposed so as to stand in a substantially vertical direction when the space is partitioned (see FIG. 4 described later). However, the present invention is not limited to this, and it may be arranged so as to be inclined or substantially horizontal with respect to the vertical direction. In the present embodiment, the description will be made assuming that they are arranged so as to stand in a substantially vertical direction. 1B to 1F show a state in which the panel assembly 100 stands in a substantially vertical direction. That is, in FIG. 1B, the direction perpendicular to the paper surface is the vertical direction, and in FIGS. 1C to 1F, the vertical direction is the vertical direction toward the paper surface.

  As shown in FIG. 1 (c) or (e), the panel assembly 100 is a panel formed in a substantially rectangular shape (see FIG. 1 (a)), and has a thickness over substantially the entire length of the end surface portion 111a. A panel 111 as a first panel having a concave portion 111b whose cross-sectional shape in the direction is formed in a substantially arc shape, and a panel formed in a substantially rectangular shape in the thickness direction over the entire length of the end surface portion 112a. When the projecting portion 112b having a substantially arc shape in cross section is provided and the end surface portion 112a faces the end surface portion 111a of the panel 111, the projecting portion 112b and the recessed portion 111b are fitted to each other. And a panel 112 as a second panel that is arranged in such a manner. Furthermore, the panel assembly 100 is a connecting means for connecting the panel 111 and the panel 112 so as to be relatively rotatable. When the end surface portion 111a of the panel 111 and the end surface portion 112a of the panel 112 face each other, the panel assembly 100 111 and the panel 112 are provided with a hinge 120 as a connecting means for movably connecting in a direction away from each other.

  The panel assembly 100 is typically formed in a series by a plurality of panels being rotatably connected via a hinge 120. For example, when used in a garage door 200 (see FIG. 4) as a movable partition assembly according to a second embodiment of the present invention described later, the panel assembly 100 includes four panels 111, 112, 113 (refer FIG. 4) and 114 are comprised. As a result, the garage door 200 (see FIG. 4) can be easily installed, and when the panel assembly 100 moves while changing its direction as will be described later, the turning radius of the panel is shortened. Because the distance required for the conversion of the is short, versatility is high. In the present embodiment, the panel assembly 100 will be described as including four panels 111, 112, 113 (see FIG. 4) and 114.

  The four panels 111, 112, 113 (see FIG. 4) and 114 do not need to distinguish between the first panel and the second panel. In short, the two panels whose end faces face each other. One is a first panel and the other is a second panel. In other words, for example, if the panel 111 is the first panel, the panel 112 may be the second panel, and if the panel 112 is the first panel, the panel 113 may be the second panel. . Further, the four panels 111, 112, 113, and 114 are simply referred to as a panel 110 when there is no need to explain them individually. Further, in the following description with reference to FIG. 1, the panel 113 (see FIG. 4) is not shown for easy understanding.

  FIG. 1A is a partially exploded perspective view of one panel 110. In this embodiment, panel 110 is formed in a substantially rectangular shape so that the long side direction is substantially horizontal when the space is partitioned (see FIG. 4). End surfaces of two panels 110 facing each other, for example, end surfaces 111a when the two panels are a panel 111 (see FIG. 1C) and a panel 112 (see FIG. 1C), respectively. 112a (refer FIG.1 (c)) is the end surface part of the said long side. The panel 110 is mainly made of wood and is coated with an inner surface material 160 as a second surface material formed of a flame-retardant plywood and a fire-retardant flame retardant containing a boric acid compound, an ammonium compound, and a phosphoric acid compound. An outer surface material 161 as a first surface material, and a frame assembly 162 as a reinforcing material that is disposed between the inner surface material 160 and the outer surface material 161 and reinforces the inner surface material 160 and the outer surface material 161. It is comprised including. Typically, as will be described later with reference to FIG. 4, when the panel 110 is installed so as to partition the outdoor and indoor, the inner surface material 160 is on the indoor side and the outer surface material 161 is on the outdoor side. It is arranged. In the following description, unless otherwise specified, the long side direction of the panel 110 is described as a direction that is substantially horizontal when the space is partitioned (see FIG. 4).

  The frame assembly 162 is formed of a wooden square member, and is formed of two vertical members 162a and 162b disposed substantially parallel to each other, and is also formed of a wooden square member, and is substantially perpendicular to the vertical members 162a and 162b. As described above, the two horizontal members 162c and 162d arranged substantially parallel to each other are formed to have a substantially rectangular frame structure. Further, the frame assembly 162 includes a vertical beam 162e disposed substantially parallel to the vertical members 162a and 162b and a horizontal beam 162f disposed substantially parallel to the horizontal members 162c and 162d. The

  The inner surface material 160 is formed of a flame retardant plywood having a performance that is difficult to burn and hard to break. For example, as a plywood subjected to a flame retardant treatment using a fire retardant such as ammonium phosphate or ammonium nitrate, a flame retardant veneer, It is preferable to use at least one type of plywood selected from a group of plywood usually called a flame retardant china veneer or a flame retardant china plywood, but any plate-like member may be used. In the present embodiment, the inner surface material 160 uses a flame-retardant ceramic plywood. Here, the flame-retardant plywood is preferably a material that does not cause any harmful deformation, melting, cracking, or other damage in the case of fire in a building material when fire heat from a normal fire is applied. .

  The outer surface material 161 is formed of a peeling material coated with a fire retardant flame retardant containing a boric acid compound, an ammonium compound, and a phosphoric acid compound, which has the ability to prevent ignition of wood and make it difficult to burn. Here, the fire retardant flame retardant containing a boric acid compound, an ammonium compound, and a phosphoric acid compound is, for example, Fire Freeze (trade name, manufactured by Grandy Co., Ltd.) or Fire Letter Dent fire retardant water (trade name, manufactured by Ad Cosmic Co., Ltd.). ) And the like. For example, when the fireproof flame retardant is a boric acid compound as a main component, the boric acid compound undergoes an endothermic decomposition reaction at a high temperature of 250 ° C. or more, and the temperature of the peeling material is suppressed to the ignition temperature or lower. Furthermore, the water of crystallization in the component makes the fire extinguishing function work. Furthermore, this reaction produces a non-combustible product, which reduces the concentration of combustible gas generated from the stripping material. On the other hand, the non-combustible product adheres to the peeled material, thereby preventing the influence on the surroundings. As the outer surface material 161, for example, it is preferable to use at least one kind of peeling material selected from the group consisting of rice pine, teak material, timber material, potato material, Niyato material, etc., and the dry specific gravity of the wood is 0. The peeled wood having a specific gravity of 5 to 1.00, preferably 0.55 or more is preferable, but any plate-like member may be used. In the present embodiment, the outer surface material 161 is made of rice pine.

  The panel 110 uses a flame-retardant plywood for the inner surface material 160, so that, for example, even if heat is transmitted to the back surface of the inner surface material 160 due to a flame or the like during a fire, the progress of the burning of the panel 110 is remarkably slowed. Can do. In addition, by using a peeling material in which a fire retardant flame retardant containing a boric acid compound, an ammonium compound, and a phosphoric acid compound is applied to the outer surface material 161, the outer surface material 161 does not burn even when in contact with the flame, and the flame is on the back surface of the outer surface material 161. While preventing penetration, the expansion and contraction of the panel 110 can be prevented.

  As shown in FIG. 1B, the panel 110 has two end faces facing each other, for example, two panels 110, a panel 111 (see FIG. 1C) and a panel 112 (see FIG. 1B). 1 (c)), the roller 170 is provided at the edge that intersects the end surface portions 111a and 112a (see FIG. 1 (c)). Typically, at least two rollers 170 are attached to one panel 110, and two edge portions in a direction intersecting with an end surface portion of the long side of the panel 110 via the roller bracket 171. Is attached. That is, the two rollers 170 are respectively disposed at the edge of the short side of the panel 110. The short side direction of the panel 110 is the two slide rails 210 described later when the panel assembly 100 is used in a garage door 200 (see FIG. 4) according to a second embodiment of the present invention described later. , 220 (see FIG. 4).

  Here, the edge part of the panel 110 is a concept including the end surface part of the panel 110. For example, from the both end surface parts of the short side direction or the long side direction of the panel 110, for example, a width of about 20 to 50 mm, respectively, Includes a portion having a width of about 30 to 40 mm. In the present embodiment, each edge portion of panel 110 is a portion having a width of about 35 mm from the end surface portion. More preferably, when the panel assembly 100 is attached to a garage door 200 (see FIG. 4) according to a second embodiment of the present invention described later, the garage door is viewed from the outer surface material 161 side. It is good to set it as the range which cannot be exposed and exposed through the opening part 320 (it mentions later in FIG. 4) formed in the surrounding wall 300 (it mentions later in FIG. 4) to which 200 is attached. In other words, it is preferable that the panel assembly 100 and the peripheral wall 300 overlap each other.

  FIG. 2 is a partial detailed cross-sectional view including the end surface portion 111a and the end surface portion 112a of the panel assembly 100 according to the first embodiment of the present invention. In addition, in this figure, (a), (b) shows the state at the time of the panel assembly 100 partitioning a space and standing upright as mentioned later in FIG. (A) shows a state in which the weight of the upper panel 111 is applied to the lower panel 112 in the vertical direction, that is, a normal state in which the panel assembly 100 partitions the space. These show the state which the panel 111 does not add the weight of the panel 111 to the lower panel 112, here, the state where the panel assembly 100 is lifted upward in order to open the space. When the panel assembly 100 is used, for example, in a garage door 200 (see FIG. 4) described later, when the panel assembly 100 shifts from a normal state where the space is partitioned to a state where the space is opened, as shown in FIG. Then, it is once lifted up in the vertical direction. Furthermore, (c) is a figure which shows the state which the panel 111 and the panel 112 rotated relatively from the state which the panel assembly 100 stood in the perpendicular direction. In other words, for example, when the panel assembly 100 is used in a garage door 200 (see FIG. 4) described later, the panel assembly 100 shifts from a normal state where the space is partitioned to a state where the space is opened. FIG. 5 is a view showing a state when the guide moves by two slide rails 210 and 220 (see FIG. 4) to be described later and the direction of the movement is gradually changed. (D) is a partial detailed sectional view of a protrusion 111c described later.

A plurality of hinges 120 are installed on the inner surface material 160 side of the panel assembly 100 along end surfaces of the two panels 110 facing each other (see also FIG. 4). For example, when the two panels 110 are the panel 111 and the panel 112, respectively, as shown in this figure, the plurality of hinges 120 are attached along the end surface portions 111a and 112a. Are connected so as to be relatively rotatable about the rotation axis 122.
Details of the configuration of the hinge 120 will be described with reference to FIG.

  As described above, the panel 111 as the first panel has the concave portion 111b in which the cross-sectional shape in the thickness direction is formed in a substantially arc shape over the substantially entire length of the end surface portion 111a. The panel 112 typically has a convex portion 112b having a substantially arc-shaped cross section in the thickness direction over substantially the entire length of the end surface portion 112a.

  Here, the thickness direction means a direction in which the inner surface material 160, the outer surface material 161, and the frame assembly 162 that form the panel 111 and the panel 112 overlap. This refers to the cross-sectional shape in which the cross sections of the surface material 160, the outer surface material 161, and the frame assembly 162 appear in layers. Here, the cross sections in the thickness direction of the end surface portion 111a and the end surface portion 112a are vertical cross sections in the direction intersecting the end surface portion 111a and the end surface portion 112a. Furthermore, here, the substantially total length of the end surface portion 111a and the end surface portion 112a means the substantially total length in the direction along the end surface portion 111a and the end surface portion 112a in a direction substantially perpendicular to the thickness direction.

  The concave portion 111b of the panel 111 is formed so that the longitudinal cross-sectional shape in the thickness direction is a substantially arc shape. On the other hand, the convex part 112b of the panel 112 is formed so that it may protrude so that the longitudinal cross-sectional shape of thickness direction may become a substantially circular arc shape. Here, the arc radius of the longitudinal cross-sectional shape of the concave portion 111b may be, for example, 1 mm to 6 mm, preferably 2 mm to 3 mm longer than the arc radius of the vertical cross-sectional shape of the convex portion 112b. When the end surface portion 112a faces the end surface portion 111a, the convex portion 112b and the concave portion 111b are fitted to form a substantially uniform gap. The convex part 112b and the concave part 111b are formed such that the center of the substantially arc is substantially coincident with a rotation axis 121 of a hinge 120 (to be described later), which is the center of relative rotation between the panel 111 and the panel 112. That is, even when the panel 111 and the panel 112 rotate relatively, the gap between the convex portion 112b and the concave portion 111b is maintained at a substantially uniform and substantially constant interval. As a result, the gap between the convex portion 112b and the concave portion 111b expands with the relative rotation of the panel 111 and the panel 112, and the dust becomes clogged or the finger is drawn into the gap. There is nothing to do.

  Further, the concave portion 111b is formed to include a protruding portion 111c protruding from a substantially arc shape of the concave portion 111b over substantially the entire length of the end surface portion 111a on the side where the hinge 120 described later is located. When the panel 111, the end surface portion 111a, and the end surface portion 112a of the panel 112 face each other, the protruding portion 111c is formed so as to be able to contact the convex portion 112b of the end surface portion 112a.

  In the present embodiment, the protrusion 111c is formed so that the longitudinal cross-sectional shape in the thickness direction is a substantially quadrangular shape, more preferably a substantially trapezoidal shape as shown in FIG. Specifically, in the present embodiment, the protrusion 111c is a side surface opposite to the hinge 120 side with respect to the surface that contacts the convex portion 112b when the end surface portion 111a and the end surface portion 112a face each other. However, it is formed to have an inclination of, for example, about 20 ° to 45 °, preferably about 25 ° to 30 °, and here about 30 °.

  The protrusion 111c is formed so that the vertical cross-sectional shape in the thickness direction is substantially trapezoidal, so that the panel 111 and the panel 112 are inclined (for example, as shown in FIG. 2C). In such a state, the end surface portion 111a and the end surface portion 112a face each other, and the panel 111 and the panel 112 form one surface without inclination (for example, FIG. 2A). (The state as shown in (b)), the edge on the hinge 120 side of the convex portion 112b can be slid while rubbing the substantially trapezoidal slope so that the relative rotation is smoothly performed. It can be carried out. In other words, the side surface of the projection 111c opposite to the hinge 120 side is not replaced with the edge of the convex portion 112b on the hinge 120 side. In addition, the surface that comes into contact with the convex portion 112b when the end surface portion 111a and the end surface portion 112a are opposed to each other, for example, is a sufficiently wide surface as compared with the case where the longitudinal cross-sectional shape is formed in an arc shape. As a result, it is possible to reliably block the gap air and the like.

  Further, the protrusion 111c is formed on the end surface portion 111a on the side where the hinge 120 is located, so that the end surface portion 111a and the end surface portion 112a face each other, and the panel 111 and the panel 112 have no inclination. From the state where one surface is formed (for example, the state shown in FIGS. 2A and 2B), the panel 111 and the panel 112 are inclined (for example, FIG. 2C ), The projection 111c is immediately detached from the convex 112b at a small turning angle, so that even if foreign matter such as dust is caught, the operation is hardly hindered. There is an advantage that can be done.

  FIG. 3 is a partial detailed sectional view including the hinge 120 of the panel assembly 100 according to the first exemplary embodiment of the present invention. Here, this figure is referred in order to explain a specific configuration of the hinge 120. FIG. 3A is a diagram showing the hinge 120 in a state where the weight of the upper panel 111 is applied to the lower panel 112 in the vertical direction (corresponding to FIG. 2A), FIG. ) Is a view showing the hinge 120 in a state (corresponding to FIG. 2B) once lifted upward in the vertical direction when the panel assembly 100 is moved.

  The hinge 120 is a rotation axis attached to either the panel 111 as the first panel or the panel 112 as the second panel, here, the panel 112, and is relative to the panel 111 and the panel 112. Of the rotation axis 121 that is the center of rotation and the panel 111 as the first panel or the panel 112 as the second panel, the rotation axis 121 that is not attached, here the rotation that is attached to the panel 111 A bearing, which is formed in a substantially cylindrical shape and includes a rotating bearing 122 that rotates around the rotating shaft core 121.

Further, as shown in FIG. 3B, the hinge 120 is configured to form a play a as a gap between the rotary shaft core 121 and the inner wall of the rotary bearing 122. Here, in the case of the play “a” of the hinge 120, the concept includes a length of a gap between the rotary shaft core 121 and the inner wall of the rotary bearing 122. Here, the play a is a gap in a direction in which the panel 111 and the panel 112 are relatively separated when the end surface portion 111a of the panel 111 and the end surface portion 112a of the panel 112 face each other, that is, the panel assembly 100. Is a gap in the vertical direction when arranged in a substantially vertical direction. The outer diameter of the rotation axis 121 _{d 0,} the inner diameter of the rotary bearing 122 if the _{D i,} a play a = _{D i} -d _0.

  The rotation axis 121 is formed in a substantially cylindrical shape. The rotation axis 121 is housed in a groove 123 formed on the inner surface material 160 side of the panel 112 in the direction along the end surface portion 111a (see FIG. 2) and the end surface portion 112a (see FIG. 2). At both ends of the rotation shaft core 121, rotation shaft core fixing portions 125 are formed, respectively. The rotating shaft core fixing portion 125 is formed in a substantially cylindrical shape having substantially the same radius as the rotating bearing 122 and is substantially coaxial with the rotating shaft core 121. Further, the rotation axis fixing part 125 is fixedly attached to the panel 112 by screws or the like via a plate-like part 126 extending from the rotation axis fixing part 125. The rotary bearing 122 is fixedly attached to the panel 111 with screws or the like via a plate-like portion 124 extending from the rotary bearing 122. Further, the rotary bearing 122 is attached so that the rotary shaft core 121 is inserted inside the substantially cylindrical shape and can be rotated around the rotary shaft core 121 so as to be sandwiched between the two rotary shaft core fixing portions 125. It is done. The hinge 120 in the present embodiment is a connecting means for connecting the panel 111 and the panel 112 so as to be relatively rotatable. When the end surface portions face each other, the panel 111 and the panel 112 are connected to each other. Other types of hinges such as a pulling hinge and a hooking hinge may be used as long as the hinge is connected so as to be movable in a relatively distant direction.

  The panel 111 and the panel 112 are connected to each other by a hinge 120 so that the panel 111 and the panel 112 can move relatively away from each other when the end surface 111a of the panel 111 and the end surface 112a of the panel 112 face each other. Is done. As described above, the hinge 120 has the play a between the rotary shaft core 121 and the rotary bearing 122, and therefore, the length of movement of the panel 111 and the panel 112 in the direction away from each other, in other words, For example, the maximum gap b (see FIG. 2B) between the protrusion 111c and the convex 112b is limited based on the play a of the hinge 120.

  Returning to FIG. 2, in the present embodiment, the maximum gap b between the projecting portion 111 c and the convex portion 112 b is smaller than or substantially equal to the play a of the hinge 120. In the present embodiment, a description will be given assuming that the maximum gap b between the protrusion 111c and the convex 112b is smaller than the play a of the hinge 120. That is, when the maximum gap b between the protruding portion 111c and the convex portion 112b is smaller than the play a of the hinge 120, the vertically lower portion of the outer peripheral surface of the rotary shaft core 121 and the inner peripheral surface of the rotary bearing 122 To the lower part of the vertical direction, the movement in the direction in which the panel 111 and the panel 112 are separated is restricted (see FIG. 3B). The movement in the direction in which the panel 111 and the panel 112 approach is restricted by the protrusion 111c and the convex 112b contacting each other. By configuring in this way, it is possible to allow a slight error in the installation position of the hinge 120 and the like in the manufacturing process as compared with the case where the maximum gap b and the play a of the hinge 120 are substantially equal. That is, manufacture becomes easy.

  For example, when the panel assembly 100 is used in a garage door 200 (see FIG. 4), which will be described later, in a normal state where the panel assembly 100 partitions a space, the lower panel 112 is connected to the upper panel 111. The self weight is applied in the vertical direction (FIG. 2A). At this time, the protrusion 111c and the convex 112b are in contact with each other, so that the gap between the protrusion 111c and the convex 112b becomes 0 (zero), and the surface of the protrusion 111c that faces the convex 112b, The projecting portion 112b is in close contact with the convex portion 112b. As a result, in the state where the panel assembly 100 partitions the space, the gap between the panel 111 and the panel 112 is almost completely eliminated at the portions of the protruding portion 111c and the convex portion 112b, and for example, the gap air is prevented. Excellent blocking performance can be demonstrated.

  Further, when the panel assembly 100 is guided and moved by two slide rails 210 and 220 (see FIG. 4), which will be described later, to open the space, the upper panel 111 has a protrusion 111c and a convex shape. A maximum gap b is provided between the portion 112b and the portion 112b is once suspended upward in the vertical direction. Further, by continuing to move, each panel is relatively rotated as the guided direction of movement changes while the panels after panel 111 are also brought. Here, before the relative rotation of each panel, the preceding panel is once suspended, and the vertical lower portion of the outer peripheral surface of the rotary shaft core 121 and the inner peripheral surface of the rotary bearing 122 are vertically aligned. The lower part of the direction comes into contact. That is, the gap between the protrusion 111c and the convex 112b extends to the maximum gap b. Since there is a gap between the protruding portion 111c and the convex portion 112b, adjacent panels do not rub with each other as the panels rotate relative to each other, so that the direction of the panel assembly 100 is changed. Here, the movement from the closed state to the open state as described later can be performed smoothly and easily.

  Here, the maximum gap b between the protrusion 111c and the convex portion 112b is, for example, about 0.3 to 0.9 times, preferably about 0.4 to 0.7 times the play a of the hinge 120. Good. If the maximum gap b is shorter than 0.3 times the play a of the hinge 120, the maximum gap b when the panel is once lifted upward in the vertical direction is too small, changing the direction of the panel assembly 100. The movement may not be smooth and easy. Further, if the length of the hinge 120 is longer than 0.9 times of the play a, a gap is likely to be generated between the end surface portions of the adjacent panels in the normal state where the panel assembly 100 partitions the space. It may not be possible to properly block the space.

  Here, the protrusion 111c is described as being formed so that the vertical cross-sectional shape is substantially trapezoidal, but in short, it may be formed in a substantially arc shape of the recessed portion 111b. You may form in a semicircle shape. Further, the protrusion 111c may be formed by a substantially arc having a shorter radius of curvature than the substantially arc of the concave portion 111b.

  Continuing to refer to FIG. In the present embodiment, panel assembly 100 has heat expandability, and is formed over substantially the entire length of end surface portion 111a of panel 111 or end surface portion 112a of panel 112, in this embodiment, end surface portion 111a of panel 111. And a first filler 130 filled in the groove 130a.

  The groove 130a is formed along the side surface opposite to the hinge 120 side of the protrusion 111c of the concave portion 111b. As will be described later, when the panel assembly 100 partitions the space (see FIG. 4), the panel 111 and the panel 112 are disposed so as to stand in a substantially vertical direction. Accordingly, the groove 130a is formed on the upper surface in the vertical direction of the portion where the panel 111 and the panel 112 fit, that is, the end surface portion 111a when the panel assembly 100 partitions the space (see FIG. 4). The first filler 130 is filled in the groove 130a. With this configuration, combustible dust and debris accumulate in the groove 130a while the panel assembly 100 repeatedly moves. For example, in the event of a fire or the like, a flame is blown on one side of the panel assembly 100 ( For example, the risk of facilitating transmission from the outer surface material 161 side to the other surface side (for example, the inner surface material 160 side) can be reduced.

  In the present embodiment, one groove 130a is formed on the side opposite to the hinge 120 side of the protrusion 111c. The first filler 130 is filled in the single groove 130a. A plurality of grooves 130a and first fillers 130 may be provided. That is, two grooves 130a may be formed in the end surface portion 111a and the concave portion 111b, and the first filler 130 may be filled in both of the two grooves 130a. In this way, for example, in the event of a fire, the flame is transmitted from one surface side (for example, the outer surface material 161 side) of the panel assembly 100 to the other surface side (for example, the inner surface material 160 side). The risk of making it easier can be reduced more reliably.

  The depth of the groove 130a is, for example, 1 mm to 2 mm, preferably about 1.6 mm. The width of the groove 130a is about 5 mm to 15 mm, preferably about 12 mm. By comprising in this way, the 1st filler 130 demonstrated below can be filled with an appropriate quantity, and the thermal expansion performance of the 1st filler 130 can fully be exhibited.

  The first filler 130 is formed of a material having heat expandability, typically, an expandable fireproof and heat resistant functional material. In the present embodiment, the first filler 130 includes water-insoluble and expandable mineral particles, a halogen-free binder that is thermoplastic or thermosetting, and a phosphorus-containing flame retardant. A flexible solid fireproof sealing composition. The first filler 130 is typically a flexible solid fireproof sealing composition having a softness of about 0.01 to about 3.75 mm. It should be noted that the solid fireproof sealing composition has a clear shape that is flexible but returns to its original state after a slight deformation, so that it can be distinguished from a putty-like material that is soft and malleable at room temperature.

  The water-insoluble and expandable mineral particles typically comprise a mixture of an oxyboron compound, expandable graphite, or a mixture thereof and a hydrated alkali metal silicate as the expandable material. The water-insoluble and expandable mineral particles may simply contain expandable graphite. The amount of water-insoluble and expandable mineral particles may be, for example, from about 10 to about 70% by weight, preferably from about 25 to about 60% by weight, based on the total weight of the solid fireproof sealing composition.

The hydrated alkali metal silicate may be, for example, a granular hydrated alkali metal silicate. Preferred alkali metal silicates, water content of about 5 to about 30 wt%, silicon dioxide (SiO ₂₎ sodium to oxide _(Na 2 O) ratio of about 2.0: 1 to about 3.75: 1 range Granular sodium silicate having a particle size range of about 0.2 mm to 2.0 mm (ie, about 95% of the particles are greater than 0.2 mm).

A preferred water-insoluble and expandable mineral grain is a mixture of alkali metal silicates represented by the formula M ₂ O: xSiO ₂ , where M is an alkali metal. The mixture also includes at least one oxyboron compound that may be selected from boric acid and borates of group I, II elements, and water. The weight ratio X ranges from about 1.5 to about 4, the molar ratio of boron to M is between about 0.2 to about 0.9, and water accounts for about 5-15% by weight of the total composition. Constitute. Examples of silicates that can be used include sodium silicate, lithium silicate, and potassium silicate. Examples of oxyboron compounds that can be used include metaborate, tetraborate, perborate, polyboric acid group, boric acid, perovite, calcium metaborate, magnesium borate, and boric acid. Zinc etc. are mentioned.

  When the water-insoluble and expandable mineral particles are mixed with the silicate, other expandable compounds may be used. Examples of the expandable compound include expandable graphite, vermiculite, pearlite, NaBSi, glass particles, mica, inorganic and organic foaming agents, and mixtures thereof. The expandable graphite may be mixed with, for example, a granulated hydrated alkali metal silicate expandable composition.

  A halogen-free binder, typically a halogen-free organic binder, is a thermoplastic or thermosetting binder. The use of halogen-free binder materials eliminates the risk of producing toxic and corrosive halogen acid gases during a fire. However, when using a binder material that does not contain halogen, it is preferable to add a flame retardant described below. The amount of binder that is halogen-free and is thermoplastic or thermosetting is, for example, from about 10 to about 50%, preferably from about 12 to about 50% by weight, based on the total weight of the solid fireproof sealing composition. It may be about 40% by weight.

  Thermoplastic binders typically have long polymer chains with few chemical bonds that, when present, serve to crosslink the chain. Thermoplastic binders usually soften when heated and can be molded into the desired shape. Subsequent reheating serves to soften the material again. Examples of the thermoplastic binder include acrylic acid polymer, ethylene vinyl acetate copolymer, natural rubber, styrene-butadiene copolymer, butadiene-acrylonitrile copolymer, polyisoprene, polyptadiene, polyvinyl acetate, polyethylene terephthalate, polyethylene. , Substantially linear polymers such as polypropylene and polystyrene, and combinations and mixtures of these polymers. The term “substantially linear” as used with respect to these materials means that the average number of branches is not more than 3 or 4 per polymer chain, preferably 1 or 2, and most preferably 0. Point to.

  A thermosetting binder refers to a polymer that typically cures by causing a crosslinking reaction upon heating. If the crosslink density is high enough, the material tends to be hard, infusible and insoluble. The shape of such materials typically cannot subsequently change permanently when warmed. Two or more liquid components can be reacted to form a thermosetting polymer. For example, a multifunctional amine and a multifunctional epoxy may be reacted to form an epoxy system. Examples of the thermosetting binder include epoxy, phenol, polyester, silicone, polyurethane, and polyimide. Furthermore, preferred thermosetting binders include binders that can be crosslinked, for example, by addition of a crosslinking agent or electron beam, or exposure to both suitable energy sources. Examples of the material include natural rubber, styrene-butadiene copolymer, butadiene-acrylonitrile copolymer, and polyptadiene.

  More preferable thermoplastic or thermosetting binders include synthetic or natural isoprene rubber, ethylene propylene rubber, EPDM rubber, and polyptadiene. The most preferred binder is a binder containing an ethylene vinyl acetate copolymer. For example, a blend of materials such as ethylene vinyl acetate and synthetic isoprene rubber may be used.

  The phosphorus-containing flame retardant is preferably a material containing phosphorous acid and / or nitrogen that promotes carbonization of the organic binder described above by forming an acid upon heating. Preferred examples of the phosphorous acid-containing compound include compounds containing ammonium polyphosphate (APP). An endothermic material is also a suitable flame retardant. A preferred endothermic material is, for example, alumina trihydrate. The amount of the phosphorus-containing flame retardant may be, for example, from about 10 to about 50% by weight, preferably from about 15 to about 40% by weight, based on the total weight of the solid fireproof sealing composition.

  The first filler 130, that is, the solid fireproof sealing composition, is added with other optional components such as a filler, a pigment, and a processing aid to add the characteristics of the solid fireproof sealant composition. It may be enhanced. Furthermore, since a thermosetting binder may be used as the binder, for example, a curing agent such as an organic peroxide such as dicumyl peroxide or a crosslinking agent may be present.

  In addition, a plasticizer, preferably a flame retardant plasticizer, such as an organic phosphate plasticizer, may be added to the solid fireproof sealing composition. The amount of the plasticizer may be appropriately adjusted in order to prevent the composition from becoming too soft or putty-like. A plasticizer may be used as a processing aid to extrude or mold the sealant into the desired shape. Further, for example, antioxidants such as hindered phenols and aromatic amines and ozone deterioration inhibitors may be added. For example, a colorant such as an organic substance such as a pigment, a lake or a dye, or an inorganic substance such as titanium oxide, zinc oxide or iron oxide may be added as desired.

  Solid fireproof sealing compositions are typically produced by combining the ingredients used through a high shear mixing operation, such mixing being made substantially free of volatiles. The composition is typically made by high shear mixing of the various components using, for example, a twin roll mill, a Banbury mixer, or preferably a twin screw extruder with heating and cooling capabilities and controlled processing temperatures. .

  The state containing substantially no volatile matter means that the component of the composition contains no volatile organic solvent, and the binder also contains substantially no water (not shown) (for example, 0.25% by weight). Means that high shear mixing is performed. This water is water other than bound water, which is water that does not evaporate until the material is heated to at least 100 ° C. (preferably at least 150 ° C., more preferably at least 250 ° C.).

  The binder is pre-dried, for example, in an oven (not shown), or if it is dry, it is added directly to the mixing chamber (not shown) and mixed until completely mixed. Next, while continuing the mixing operation, a filler, a processing aid, a char-forming resin, a wax, a colorant, a flame retardant, an antioxidant, an ozone degradation inhibitor, a curing agent, and a plasticizer are added as appropriate. The last component added is usually an expandable material. The composition is typically mixed until it is homogeneous and smooth (ie, free of lumps).

  In the present embodiment, as described above, the first filler 130 uses the solid fireproof sealing composition. Examples of the solid fireproof sealing composition include a fire barrier fire spreader (trade name, manufactured by Sumitomo 3M). By using the solid fireproof sealing composition for the first filler 130, for example, when the flame passes through the gap between the end surface portion 111 a and the end surface portion 112 a caused by heat in the event of a fire or the like, the flame is the first By contacting the filler 130, the first filler 130 expands instantaneously. The expanded first filler 130 closes the gap between the end surface portion 111a and the end surface portion 112a generated by heat, so that the flame is transferred from one surface side (for example, the outer surface material 161 side) of the panel assembly 100 to the other. Can be prevented from penetrating to the surface side (for example, the inner surface material 160 side).

  In the above description, when the panel assembly 100 partitions the space (see FIG. 2), the first filler 130 is applied to the concave portion 111b of the end surface portion 111a of the panel 111 located on the upper side in the vertical direction. Although described as filling the groove 130a to be formed, the groove (not shown) formed in the convex part 112b of the end surface part 112a of the panel 112 located on the lower side in the vertical direction may be filled. . The first filler 130 may be filled in grooves (not shown) formed in both the end surface portion 111a and the end surface portion 112a.

  Note that the description of the end surface portion 111a, the end surface portion 112a, the concave portion 111b, the convex portion 112b, the protruding portion 111c, the first filler 130, the groove 130a, etc. will be made in the fitting portion between the panel 111 and the panel 112. However, it goes without saying that the fitting portion between the panel 112 and the panel 113 (see FIG. 2) and the fitting portion between the panel 113 and the panel 114 have substantially the same configuration. Further, the panel assembly 100 may be configured not to include the first filler 130 and the groove 130a.

  Again, FIG. 1 continues the description of the configuration of the panel assembly 100. As described above, the panel assembly 100 includes four panels 111, 112, 113 (see FIG. 4) and 114, and is formed in a substantially rectangular shape as a whole. The panel assembly 100 includes a frame weather seal portion 180 as a first abutting portion formed at the edge of the substantially rectangular three sides, and a first portion formed at the edge of the remaining substantially rectangular shape. And a ground weather seal portion 181 as two contact portions.

  Specifically, as shown in FIGS. 1B and 1D, the frame weather seal portion 180 is formed on both the panels 111 positioned at the uppermost stage in the vertical direction when the panel assembly 100 partitions the space. The edge of the short side and the edge of the long side on the upper side in the vertical direction, the edge of both short sides of the panel 112 located on the lower side in the vertical direction of the panel 111, and the panel 113 located on the lower side in the vertical direction of the panel 112 (see FIG. 4) and the edges of both short sides of the panel 114 located on the lower side in the vertical direction of the panel 113 (see FIG. 4). That is, the frame weather seal portion 180 is configured by a substantially U-shaped edge portion excluding the edge portion on the lower side in the vertical direction of the panel assembly 100. Here, as described above, the edge of the panel 111 or the like or the edge of the panel assembly 100 is a concept including the end surface, and is a portion within a predetermined range from the end surface. The end surface portion of the panel assembly 100 is formed by combining the end surface portions of the four panels 111, 112, 113 (see FIG. 4) and 114.

  The frame weather seal portion 180 is filled in the two grooves 140a formed in the substantially U-shape along the end surface portion of the panel assembly 100 on the surface of the outer surface material 161, and the two grooves 140a. The second filler 140 having heat expandability is included. FIG. 1A illustrates a groove 140 a and a second filler 140 formed in the panel 111. The groove 140a and the second filler 140 are formed in a substantially U-shape in which the lower side in the vertical direction is open on the panel 111. Although not shown here, the groove 140a and the second filler 140 are formed substantially parallel to both edges in the short side direction in the panels 112, 113, and 114.

  Similar to the first filler 130, the second filler 140 is formed of a material having heat expandability, typically, an expandable fireproof and heat-resistant functional material. In the present embodiment, the above-described solid fireproof material is used. A sealing composition is used. Similarly, the dimension of the groove 140a may be the same as that of the groove 130a described above. Furthermore, here, the second filler 140 and the groove 140a are described as being formed two each, but it goes without saying that one may be provided.

  Specifically, as shown in FIG. 1 (f), the ground weather seal portion 181 is provided on the lower side in the vertical direction of the panel 114 positioned at the lowest level in the vertical direction when the panel assembly 100 partitions the space. Consists of long edges. That is, the ground weather seal portion 181 is configured by the edge portion on the lower side in the vertical direction of the panel assembly 100.

  The ground weather seal portion 181 includes a groove 150a formed over substantially the entire length of the end surface portion 114a on the lower side in the vertical direction of the panel 114 (here, the horizontal member at the lowest level in the vertical direction of the frame assembly 162 of the panel 114). It is configured to include a third filler 150 filled in 150a and having heat expandability, and a seat plate rubber 151 disposed so as to face the end surface portion 114a. The seat rubber 151 is a rod-shaped member having a substantially L-shaped cross section as a whole, and is formed to have substantially the same length as the entire length of the end surface portion 114a. The seat rubber 151 is fixedly attached to the end surface portion 114a, and serves as a cushion material between the ground 310 and the panel assembly 100, which will be described later with reference to FIG. The third filler 150 is formed between the end face portion 114a and the seat plate rubber 151. Note that the seat rubber 151 has a little elasticity and reliably partitions the space.

  Similar to the first filler 130 and the second filler 140, the third filler 150 is formed of a material having heat expandability, typically an expandable fireproof and heat resistant functional material. In the form, the above-described solid fireproof sealing composition is used. Similarly, the dimension of the groove 150a may be the same as that of the groove 130a described above. In the present embodiment, the third filler 150 and the groove 150a are each formed with one first filler 130. However, it goes without saying that two may be formed as long as space permits.

  For example, when the panel assembly 100 is used in a garage door 200 (see FIG. 4) according to a second embodiment of the present invention described below, the frame weather seal portion 180 guides the roller 170 to form the panel assembly. The slide rails 210 and 220 (which will be described later with reference to FIG. 4) as guide portions for guiding the movement of the three-dimensional body 100 are configured to come into contact with a peripheral wall 300 (see FIG. 4) as a fixed portion. Moreover, the ground weather seal part 181 is comprised so that it may contact | abut the ground 310 (refer FIG. 4) which forms the floor surface of the garage 3 (it mentions later in FIG. 4). The panel assembly 100 is configured to partition a space when the frame weather seal portion 180 abuts the peripheral wall 300 and the ground weather seal portion 181 abuts the ground 310.

  More specifically, the second filler 140 of the frame weather seal portion 180 described above is disposed between the outer surface material 161 at the edge on the upper side in the vertical direction of the panel 111 and the peripheral wall 300, and the panel assembly.

It is a fragmentary perspective view containing the slide rail 210 to do. Note that in FIG. 2A, illustration of a part of the peripheral wall 300 constituting the garage 3 and the ceiling 330 (see FIG. 5) is omitted for easy understanding.

  The garage door 200 includes two panel assemblies 100 in which the rollers 170 are disposed, and two guide portions serving as guide portions for guiding the rollers 170 to guide the movement of the panel assemblies 100 as shown in FIG. Slide rails 210 and 220 are provided. The garage door 200 is attached to the garage 3 that houses, for example, an automobile. In the present embodiment, the garage 3 includes a peripheral wall 300 that surrounds four sides of a space for housing the automobile, a ground 310 that forms the bottom surface of the garage 3, and a ceiling 330 that forms the top surface of the garage 3 (see FIG. 5). And an opening 320 formed in a substantially rectangular shape on any one surface of the peripheral wall 300.

  The opening 320 is formed to be slightly smaller than the panel assembly 100, and when the space is partitioned by the panel assembly 100, the opening is closed by the panel assembly 100, and the edge of the panel assembly 100 and the opening 320 are also closed. The peripheral wall 300 is formed in such a size as to overlap. The automobile can enter and leave the space defined by the peripheral wall 300, the ground 310, and the ceiling 330 (see FIG. 5) through the opening 320. The panel assembly 100 can restrict the entry and exit of the automobile through the opening 320 when the space is partitioned. In the present embodiment, when panel assembly 100 partitions the space, panel assembly 100 has an inner surface (a space side defined by peripheral wall 300 or the like) on the inner surface across panel assembly 100. The material 160 (refer FIG. 1) and the outdoor side are arrange | positioned so that it may become the outer surface material 161 (refer FIG. 1).

  The garage door 200 is further connected to the panel assembly 100, a trolley 230 that moves the panel assembly 100 along the slide rails 210 and 220, a trolley rail 240 that the trolley 230 travels, and a drive source that travels the trolley 230. And an opening / closing assisting device 260 for assisting the opening / closing movement of the panel assembly 100 by the trolley 230.

  FIG. 5 is a diagram showing a configuration of a garage door 200 according to the second embodiment of the present invention, in which (a) is a side view and (b) is an AA arrow view shown in (a). . In FIG. 5A, for easy understanding of the description, one surface of the peripheral wall 300 (the surface on the near side in the figure) is removed.

  The slide rails 210 and 220 are configured to include vertical rail portions 212 and 222 erected on both sides of the opening 320 in the horizontal direction, and horizontal rail portions 211 and 221 arranged along the ceiling 330, with corners. It is a substantially L-shaped guide rail that is smoothly bent. The slide rails 210 and 220 have mounting angles on the mounting base (not shown) in which the vertical rail portions 212 and 222 form the peripheral wall 300 and the mounting rails (not shown) in the horizontal rail portions 211 and 221 on the ceiling 330, respectively. Etc. are fixedly attached via the like.

  As shown in FIG. 5B (or FIG. 4B), the slide rails 210 and 220 are formed to have a substantially U-shaped cross section. The roller 170 of the panel assembly 100 is configured to move inside the substantially U-shape of the slide rails 210 and 220. The panel assembly 100 moves along the slide rails 210 and 220 as the rollers 170 are guided by the slide rails 210 and 220. The panel assembly 100 is guided by the slide rails 210 and 220 so that the frame weather seal portion 180 and the peripheral wall 300 come into contact with each other while standing in a substantially vertical direction, and the ground weather seal portion 181 and the ground 310 come into contact with each other. A transition can be made between a closed state in which the opening 320 is closed and an open state in which the opening 320 is opened in a substantially horizontal direction. When the panel assembly 100 transitions from the closed state to the open state, or from the open state to the closed state, each panel 110 constituting the panel assembly 100 gradually moves about the hinge 120 to move. Change direction.

  The trolley 230 is connected to the panel 111 of the panel assembly 100 via an arm 231 formed in a substantially L shape. The arm 231 is pivotally supported at both ends. The trolley 230 is attached to the trolley rail 240 and is configured to travel along the trolley rail 240. The trolley rail 240 is a rail-shaped member, and is disposed along the ceiling 330 so as to be substantially parallel to the slide rails 210 and 220 at the approximate center in the width direction of the opening 320.

  A driven roller (not shown) is attached to the outdoor end of the trolley rail 240, and a drive roller (not shown) is attached to the indoor end. The drive roller (not shown) is connected to a switch 250 as a drive source via a torque limiter (not shown) or the like. For example, an electric motor or the like can be used for the opening / closing machine 250. Further, a drive chain (not shown) is stretched between a driven roller (not shown) and a drive roller (not shown), and the drive chain (not shown) is driven by the trolley rail 240 as the switch 250 is driven. Forcibly reciprocating movement is made along. The trolley 230 described above is connected to the drive chain (not shown). Accordingly, as the drive chain (not shown) reciprocates by driving the opening / closing device 250, the trolley 230 also forcibly reciprocates along the trolley rail 240, thereby turning the arms 231 that can rotate at both ends. The connected panel assembly 100 moves along the slide rails 210 and 220, and shifts from the closed state to the open state, or from the open state to the closed state.

  Returning to FIG. 4, the opening / closing auxiliary device 260 is disposed substantially horizontally above the opening 320 in the vertical direction and is wrapped around a pipe-shaped shaft 261 supported at both ends by brackets 261 a and 261 b, and the shaft 261. It is configured to include springs 262a and 262b that are always biased in the winding direction. The opening / closing auxiliary device 260 balances the urging force of the springs 262a and 262b and the weight of the panel assembly 100, and connects the wires 263a and 263b connected to the lowermost panel 114 of the panel assembly 100 to the shaft 261, respectively. The drums 264a and 264b provided at both ends are wound and unwound. Thereby, the load concerning the opening / closing machine 250 can be reduced.

  According to the panel assembly 100 and the garage door 200 according to the embodiment of the present invention described above, for example, in the normal state in which the panel assembly 100 partitions the space, the lower panel 112 has an upper side. The panel 111 is in a state where its own weight is applied in the vertical direction, and the gap between the protrusion 111c and the convex 112b is 0 (zero). That is, the surface of the protruding portion 111c that faces the protruding portion 112b and the protruding portion 112b are in close contact with each other. The same applies to the gaps between the panels 112 and 113 and between the panels 113 and 114. Thereby, in the state where the panel assembly 100 partitions the space, the gap between the adjacent panels 110 is almost completely eliminated at the protruding portion and the protruding portion, so that, for example, a fitting portion between two panels It is possible to provide a movable partition and a movable partition that have excellent shut-off performance without passing through the gap air.

  Furthermore, when the panel assembly 100 shifts from the closed state to the open state so as to open the space, each panel 110 is once vertically opened with a maximum gap b between the protruding portion and the convex portion. It will be in the state of being lifted up in the direction. Further, by continuing the movement, each panel 110 is relatively rotated as the guided movement direction is changed while the panel 110 subsequent to the preceding panel 110 is also drawn. Here, before the relative rotation of each panel 110, the preceding panel is once suspended, and there is a gap between the protrusion and the convex portion, so that the relative rotation of each panel 110 is performed. Since the adjacent panels do not rub with each other, the movement while changing the direction of the panel assembly 100 can be performed easily and smoothly.

  Furthermore, according to the panel assembly 100 and the garage door 200 according to the embodiment of the present invention described above, for example, the flame passes through the gap between the end surfaces of the panel 110 generated by heat in the case of a fire or the like. When the flame contacts the first filler 130, the first filler 130 expands instantaneously. Since the expanded first filler 130 closes the gap between the end surfaces caused by heat, the flame is transferred from one surface side (for example, the outer surface material 161 side) to the other surface side (for example, the outer surface material 161 side). , The inner surface material 160 side) can be prevented from penetrating. Therefore, it is possible to provide a panel assembly and a garage door that can exhibit excellent fire prevention performance.

  Furthermore, when the panel assembly 100 partitions the space, in the frame weather seal portion 180, the second filler 140 is bonded to the portion where the outer surface material 161 of the panel 111 and the peripheral wall 300 are in contact with each other. When the flame passes through the gap between the outer surface material 161 and the peripheral wall 300 and reaches the frame weather seal portion 180, the second filler 140 expands instantaneously and is between the outer surface material 161 and the peripheral wall 300. Since the gap formed is blocked, flame penetration can be prevented. Further, in the ground weather seal portion 181, the third filler 150 is bonded between the end surface portion 114 a of the panel 114 and the seat plate rubber 151. Therefore, when the flame reaches the ground weather seal portion 181, Since the third filler 150 expands instantaneously and closes the gap between the end face portion 114a and the seat rubber 151, it is possible to prevent the penetration of the flame.

  Moreover, the panel 110 which comprises the panel assembly 100 uses a flame-retardant plywood for the inner surface material 160, and even if heat is transmitted to the back surface of the inner surface material 160 by a flame etc., the burning of the panel 110 progresses. Can be significantly slowed down. In addition, by using a peeling material in which a fire retardant flame retardant containing a boric acid compound, an ammonium compound, and a phosphoric acid compound is applied to the outer surface material 161, the outer surface material 161 does not burn even when in contact with the flame, and the flame is on the back surface of the outer surface material 161. While preventing penetration, the expansion and contraction of the panel 110 can be prevented.

  In addition, according to the panel assembly 100 and the garage door 200 according to the embodiment of the present invention described above, the conventional wooden panel has a simpler structure and exhibits extremely excellent shut-off performance and fire-proof performance. Cost increases can be minimized with respect to the assembly or garage door.

  Furthermore, according to the panel assembly 100 and the garage door 200 according to the embodiment of the present invention described above, for example, the provision of Article 23 of the Building Standard Law, that is, a wooden building in an area of an urban area The structure of the outer wall part that may spread fire is a soiled wall or other structure that conforms to the technical standards stipulated by a Cabinet Order with regard to semi-fire prevention performance, and uses the structural method specified by the Minister of Land, Infrastructure, Transport and Tourism, or It may also be possible to meet the requirements of the provision that it must be certified by the minister. Therefore, a panel assembly using a wooden panel or a garage door can be used for the house in the above-mentioned area, the design variation of the house design can be increased, and further, it can contribute to the beauty of the townscape.

  In the above description, the movable partition assembly is described as a garage door that partitions a garage. However, a space other than the garage, for example, a movable partition assembly that simply partitions two indoor spaces may be used. Further, the ground weather seal portion 181 has been described as being in contact with the ground 310 to partition the space, but the ground here is a concept including a floor and the like. May be partitioned. In addition, for example, the second filler 140 has been described as being filled in the groove 140a formed in the outer surface material 161. In short, if the second filler 140 is disposed between the edge of the panel 111 and the peripheral wall 300, for example. For example, if the end surface portion of the panel 111 on the upper side in the vertical direction and the peripheral wall 300 are in contact with each other, the end surface portion may be filled with a groove. Furthermore, although the garage door 200 has been described as a so-called oversliding door in the above description, it may be a so-called roll-up door. In the case of an oversliding door, the opening and closing speed is fast and the sound is low, so it is suitable for use in a quiet residential area or at night, and the dead space near the garage ceiling can also be used effectively. In the case of the roll-up type, the door can be installed even when there is no space near the ceiling of the garage.
