DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in more detail with reference to the following drawings. In FIGS. 1 to 5, A is an extendable door body, 1 is a door body constituting bar arranged parallel to the opening / closing direction constituting the extendable door body A, 3 is a link device that expands and contracts the door-body-constituting bar 1, and the link device 3 has a plurality of pivotally supported or slidably engaged ends on the door-body-constituting bar 1. The link bar 4 includes a link connecting member 5 that rotatably supports the other end of each link bar 4 to connect the link bar 4 between the door-body-constituting bars 1 so that the link bar 4 can expand and contract. is there.
[0007]
That is, the telescopic door body A of this example is installed in the opening as a see-through vertical pulling shutter that expands and contracts in the vertical direction by the guidance of the left and right guide rails 14, for example, while the link device 3 is adjacent to the opening and closing direction. By arranging each link device 3 between the door-body-constituting rails 1, the door-body-constituting rails 1 are individually extendable and retractable, and at this time, the link device 3 is connected to the door body. By arranging a plurality or one or more in the longitudinal direction of the structural beam 1, the adjacent door body structural beam 1 is used as an expansion / contraction unit, that is, an opening / closing unit, and the individual expansion and contraction is simultaneously performed in the longitudinal direction of the door body structural beam 1. The telescopic door body A can be stably expanded and closed.
[0008]
In this example, each of the door-body-constituting bars 1 is constituted by a single bar, and a number of these are arranged horizontally to form an expansion / contraction unit arranged in parallel to the opening / closing direction. The link device 3 of this example is disposed between the adjacent door body constituting bars 1 and arranged at the rear side position among the front side position and the rear side position of the door body constituting bar 1.
[0009]
In the present embodiment, four link bars 4 of the link device 3 are used in this example so that one end of each of the link bars 4 can be pivotally supported or slidably engaged with the adjacent door body constituting beam 1. At this time, two of the four are pivotally supported, and the two are respectively slidably engaged. The pivotable shaft support is performed by fixing the link bar 4 via a fixed shaft 10 so that the link bar 4 can rotate freely. The slidable engagement is performed by a movable shaft 11 installed on the link bar 4. In this example, the movable shaft 11 has an appropriate movable member 12 such as a roller or a slider at its front end. The movable member 12 is formed on the back side of the door-body-constituting bar 1 side, for example, fitted into a guide strip 2 such as a C-shaped groove or an inverted T-shaped projection, and hooked and locked. The slide movement can be smoothly and reliably performed.
[0010]
The four link bars 4 are pivotally supported by the link connecting member 5 at the other ends thereof, thereby constituting the link device 3 that can be expanded and contracted between the door-body-constituting bars 1. In this example, the link device 3 assumes an X shape.
[0011]
The link connecting member 5 of this example is formed in a circular shape as shown in the figure, for example, so as to make a decorative accent in the X-shaped link device 3, and in this example the link connecting member 5 5 is formed with a pair of shaft support members 6 in the opening and closing direction, and the pair of shaft support members 6 are connected by a rotatable connecting portion to rotate the link connection member 5 in the front-rear direction. It is designed to be freely foldable, thereby permitting the bending of each link connecting member 5 in the link device 3 and changing the direction of the telescopic door body A in the front-rear direction when the telescopic door body A is expanded and closed. In this example, it is possible to perform cross storage, such as bending or folding opening / closing of the expansion door body A with respect to a curved surface or a plurality of intersecting surfaces, cross storage of the expansion door body A, winding storage, etc. is there.
[0012]
At this time, the pivotal support of the link bar 4 by the link connecting member 5 of this example is such that each link bar 4 is positioned on the same plane between the door-body-constituting bars 1 arranged parallel to the opening / closing direction. In addition, the pivotal connection of the pair of pivotal support members 6 is made at least 1/4 circle by using the hinge 9 and one or both of the front side and the back side. In this example, it is performed toward one side on the back side.
[0013]
That is, the shaft support member 6 of this example is configured as a U-shaped section having an upward and downward facing plate 8 for forming the link receiving groove 7 for receiving the end portion of the link bar 4, and the rear surface between the bottom walls. The hinge 9 is provided on the side to form a member of the connecting portion constituting the link connecting member 5, and the pair of shaft supporting members 6 are provided from the door body constituting bars 1. The link bar 4 is received in each link receiving groove 7, and the pivotable shaft support is performed so that the link bar 4 can be rotated in the link receiving groove 7 at the time of expansion and contraction. At this time, the pivotal support is performed by fixing the link bar 4 through the fixed shaft 10 so as to be rotatable.
[0014]
FIG. 6 and subsequent figures show other examples, and FIGS. 6 to 12 are arranged so as to form a frame by providing a pair of door-body-constituting bars 1 on the front and rear sides and arranging a bar connecting member at both longitudinal ends. On the other hand, a total of eight link bars 4 can be pivotally supported or slidably engaged with the front and rear door bars 1 adjacent to each other in the opening and closing direction in the same manner as described above. The link bar 4 is used to rotate the pivotal support of the link bar 4 by the link connecting member 5 at an intermediate position between the front and rear door body-constituting bars 1, and the front and rear four bars between the door body-constituting bars 1. This is an example in which the door-body-constituting bars 1 are individually expanded and contracted individually by a link device 3 that also has an X-shape by being positioned on the same plane. The pair of members 5 The support member 6 has an oval or short shape so as to eliminate the mutual contact when the link device 3 is folded and contracted, and is provided with a wide link receiving groove 7 in the front and rear, and the link receiving groove of the shaft supporting member 6. 7 with a deeper depth, the ends of the link bar 4 are rotatably received so that they are located on the same plane, and a spacer 13 is interposed between the front and rear link bars 4 to support the shaft. The position of the hinge 9 of the shaft support member 6 is directed toward the back side of the door body constituting beam 1 so as to absorb the thickness of the door body constituting beam 1 on the rear side. It is assumed that this was done at a protruding position.
[0015]
FIGS. 13 to 16 show that three or more link devices 3, in the present example, three door body-constituting bars 1 are disposed across the link bar 4 to extend and contract the door-body-constituting bars 1 simultaneously. The example of the telescopic door body A in the case where it can be expanded and contracted simultaneously is shown. In this example, the arrangement of the link device 3 is changed to one link bar 4 out of the four X-shaped. The link connecting members 5 in the link devices 3 between the door-body-constituting bars 1 adjacent to each other in the opening / closing direction are integrated into a series having a length to reach the shaft support member 6, and the series of link bars 4 are adjacent to each other. Are arranged between the link devices 3 to be linked, and the remaining link bars 4 are arranged in the same manner as described above, so that the series of link bars 4 are connected to the link devices 3 adjacent to each other in the opening / closing direction. And link bar 4 The link bar 4 is pivotally supported by the fixed shaft 10 so as to be pivotable with respect to the door-body-constituting beam 1 that intersects with each other. Simultaneous expansion and contraction of the door-body-constituting bar 1 is performed by simultaneous expansion and contraction of the link device 3.
[0016]
The remaining configurations of the link device 3 and the like in each example of FIGS. 6 to 16 are the same as those in the above-described example, and thus the same reference numerals are given and redundant description is omitted.
[0017]
Each of the telescopic door bodies A configured as described above is installed as a see-through vertical shutter in the opening so that the telescopic door A can be individually telescopic or simultaneously telescopic, and is guided by the guide rail 14 in the opening. In these cases, the link bar 4 is arranged so as to be positioned on the same plane, so that the link device 3 is made as thin as possible, and the thickness of the extendable door body A is changed. It is possible to prevent the increase, and the arrangement of the link device 3 is not conventionally achieved by appropriately arranging a plurality, many in the longitudinal direction of the door-body-constituting beam 1, the same row in the opening / closing direction, a staggered row, etc. The link device 3 presents a unique design, and the link connecting member 5 accentuates the telescopic door body A, thereby forming the telescopic door body A with higher uniqueness. Rukoto it is, can be a unique shutter emerged from the uniform design, such as seen for example in the pipe shutter.
[0018]
By the way, the above-mentioned one that can be expanded and contracted can be expanded and closed by the same guide rail guidance as in the past. In such a case, since it is usual to push up the door in the opening / closing direction intermediate position of the telescopic door body A and to push it upward a plurality of times in the opening / closing direction, the door body structure rail 1 to be reduced However, in the case of the one that can be individually expanded and contracted, for example, the door-body-constituting beam 1 and the guide rail 14 are provided at the longitudinal end portions of each door-body-constituting rail 1, particularly at both ends. It is possible to control the expansion / contraction position of the expansion / contraction door body A so that the expansion / contraction restriction means 17 is installed between the two, and the expansion state is maintained on the opening surface and is released in the vicinity of the storage portion. Use at the same time Lever, even a manual one, it is possible to eliminate the possibility of sandwiched the hands, without the simultaneous telescopic link device 3 can be made having the characteristics of the opening member.
[0019]
At this time, for example, as shown in FIGS. 11 and 12, the expansion / contraction restriction means 17 applies the V-shaped end portion of the adjacent door body constituting beam 1 in addition to the guide of the opening / closing guide roller 15 by the opening / closing guide 16 in the guide rail 14. The guide shaft 19 for restricting expansion / contraction is installed on the bending shaft support portion at the center position, and the guide roller 19 for restricting expansion / contraction provided on the guide rail 14 is guided. The regulation guide 20 to be formed may be linear in the opening surface, and may be branched from the opening / closing guide 16 in the vicinity of the storage portion, thereby controlling the expansion / contraction position.
[0020]
Although not shown in the figure, in the telescopic door body A used as the longitudinal shutter of this example, for example, a lower door body configuration beam is connected to one end of a wire or chain, and pulleys or sprockets installed at both upper ends in the width direction are used. By connecting the balancer to the other end of these wires and chains, the balancer can cancel the opening and closing load regardless of whether it is manual or electric, and the opening and closing load can be reduced. If a chain and a sprocket are used at this time, and if the sprocket is provided with a coaxial rotation shaft that connects the sprockets so as to rotate coaxially, this may occur particularly when the individual sprockets are made extendable. It is possible to prevent the twisting of the telescopic door body width direction, that is, the door body crosspiece longitudinal direction, and smoothly open and close the door.
[0021]
Although the illustrated example is as described above, an expansion / contraction device that expands and contracts these members apart from the link device is installed at the longitudinal end portion of the door body constituting beam, and the link device is connected to the expansion / contraction device in the expansion / contraction door body. The telescopic device is used as a decorative element that decorates and expands with the expansion and contraction of the door. At this time, the telescopic device is a telescopic device for simultaneous expansion and contraction installed at both ends in the longitudinal direction of the door body constituting beam, It is assumed that a single or a plurality of link mechanisms are arranged between them, and a link device as an expansion / contraction element or a decoration element is an I-shape or S-shape via a link connecting member in addition to the above X-shape. A link bar having a linear shape, a semicircular shape, a corrugated shape, a bent shape or the like appropriately arranged so as to exhibit an appropriate shape such as an 8-character shape, and a door device adjacent to the link device The location of each building It is configured to be alternately or sequentially shifted in the longitudinal direction, or to have a scattered configuration, and the extendable door body is configured to open and close by, for example, the guide of the opposing guide rail, and is configured as a horizontally suspended shutter, for example. Open and close by guiding the guide rails, for example, by arranging a plurality of link devices in the front and rear, etc. to constitute a laterally extending telescopic gate that secures its independence, shutters that open and close these lateral pulling, telescopic gates, etc. In such a case, the telescopic door body having the link device as the individual telescopic expansion / contraction element is partially disposed on the door end side, so that the door end side of the conventional simultaneous telescopic expansion / contraction door body Opening and closing the part to obtain an opening for people to go in and out, and the link connecting member is a surface shape such as a rectangle, a rectangle, a flower, an animal, a company emblem, a letter, etc. Or the link connecting member is formed as a single member such as a single flat plate, an L-shaped plate, etc. , When making the link connecting member freely bendable, the hard shaft support part is connected by a soft connection part, for example, it is made of hard and soft integral molded resin, the shaft support member is made of cast aluminum and this is hinged The shaft support member shall be made of extruded aluminum material, and shall be connected to this by an integral aluminum hinge with an integral shaft and bearing, and the link bar for the link connection member shall be positioned before and after the link connection member. For example, when the link connecting member is pivotally foldable on both the front and rear sides when it is pivotally supported on the same axis or on a different axis and arranged on the non-coplanar surface, Leave to one of the back side The telescopic door body can be bent or bent freely, so that it can cope with changes in the bending direction such as installation of the storage part, etc. In the implementation of the present invention, including a configuration in which a series of link bars are arranged across four or more door-body-constituting bars, a telescopic door body and a door-body structure Each specific shape, structure, material, number, arrangement form, application, relationship, addition to these, etc. of the crosspiece, link device, its link bar, and link connecting member are various forms as long as they do not contradict the gist of the invention.
