Description

In the present invention, when the shoji (surface material such as a window) is attached to the window frame in a cantilevered state so that it can be freely opened (swinged open / closed), the opening of the shoji is an intermediate position between the fully open position and the fully closed position And (a half-open state) the opening window opening degree setting device.
In this specification, “outside opening” refers to the outside beyond the shoji, as viewed from the person facing the shoji (the person who performs the opening / closing operation). However, this outside does not necessarily limit “outdoors” or “outdoors”. For example, when a shoji is provided on a partition wall or the like that divides the room or the room, the outside of the shoji may be indoor or indoor.

  Further, the “intermediate position” does not limit that the shoji stops at the center between the fully open position and the fully closed position, but is an arbitrary position between the fully open position and the fully closed position except for these two positions. Shall be said.

  The extended window has a structure in which a slider is provided so as to be movable in the left-right direction with respect to an upper frame and a lower frame of the window frame, and a swing fulcrum of the shoji is joined to the slider. The one end side of the guide rail that guides the left and right movement of the slider and the shoji are linked by an arm material. Therefore, the slider moves left and right according to the opening degree of the shoji as the shoji is rocked and opened.

Conventionally, this type of sliding window has been proposed in which the opening of the shoji can be stopped at an intermediate position (maintained in a half-open state) (see Patent Documents 1 and 2).
In the technique described in Patent Literature 1, a slider (referred to as “reciprocating seat 4” in the literature) has a locking part (referred to as “lock pin 18” in the literature) attached to a slider so as to protrude upward. In addition to the plate member (referred to as “top wall 22” in the literature) provided so as to cover the slider, the latch hole (in the document “lock hole 23a, 23b "). In other words, when the slider reaches the position corresponding to the locking hole, the locking component engages with the locking hole, the slider cannot be moved, and the opening of the shoji can be stopped at the intermediate position. It is described that when the shoji stopped at the intermediate position is fully closed or fully opened, the engaging part engaged with the engaging hole is pushed down from above the engaging hole to be disengaged.

  In the technique described in Patent Document 2, the locking component (in the document) is projected so as to protrude laterally in a direction toward the inner surface of the guide rail (referred to as “first guide plate portion 1d” in the document) with respect to the slider. In the literature, the stopper 51 is provided with a spring bias, and a locking hole (referred to as a “notch 53” in the literature) is provided on the inner vertical surface of the guide rail. Is. In terms of operation, only the protruding direction (spring urging direction) of the locking component is different, and the other components are substantially the same as in Patent Document 1.

Japanese Utility Model Publication No. 8-963 (refer to [0016] to [0017] and FIGS. 2 to 4) JP-A-9-41770 (see [0055], [0058] and FIGS. 14 to 16)

  It is well known that a shoji has an action of being pulled to the outdoor side with a strong force due to a negative pressure generated when a strong wind blows on a surface directed to the outdoors. With respect to such an outdoor pulling action, the shoji is protected by a window frame that surrounds the entire periphery of the shoji and a lock device that keeps the fully closed state when it is in the fully closed state. Have. However, if a pulling action to the outdoor side occurs when the shoji is in a half-open state or a fully-open state, this action is transmitted to the link mechanism or slider connected to the shoji.

  As described above, in the intermediate stopping technology for shojis according to the conventional proposal, the sliders are provided with the locking parts to stop the left and right movements of the sliders. If this is transmitted, this action is also derived from the engaging part and the engaging part between the engaging part and the engaging hole. Along with this, the engagement state between the locking part and the locking hole may be forcibly removed, and the shoji is struck by the wind and knocked to the fully open position or fully closed position to generate an impact sound or vibration. was there.

  Furthermore, at this time, deformation or breakage occurs in the locking parts, sliders and guide rails, and eventually the window frame and shoji, and in extreme cases, the glass fitted in the shoji and the wall material around the window frame, etc. There was a risk of cracking or breakage. As a result, it has to be said that the intermediate stopping technique of the shoji according to the conventional proposal has a weak proof strength or no proof strength with respect to the pulling action to the outdoor side generated in the shoji.

  In addition, in order to release the engagement state between the locking part and the locking hole, it is necessary to insert a hand up to the position of the slider stopped at the intermediate position of the guide rail with respect to the window frame. There is a problem that the release operation is very difficult due to the fact that the part where the locking part protrudes from the hole is small and difficult to find. Further, in some cases, there is a possibility that the finger is closed between the shoji and the window frame, between the link mechanism and the slider, between the slider and the guide rail, and the like.

  The present invention has been made in view of the above circumstances, in order to be able to hold the opening of the shoji in the intermediate position between the fully open position and the fully closed position (in a half-open state) in the sliding window, The sliding door can be opened and closed as well as the operation to release the stop position to the middle position can be performed very smoothly and easily. Also, it is damaged by the pulling action to the outside (not limited to the outdoors or outdoors) generated in the shoji. It is an object of the present invention to provide a window opening degree setting device capable of preventing the occurrence of problems such as the above.

In order to achieve the above object, the present invention has taken the following measures.
That is, the opening setting device for the sliding window according to the present invention is configured such that the swinging fulcrum of the shoji that is opened outward in a cantilever state is directed to the upper frame and / or lower frame of the window frame as the shoji is opened and closed. An interlocking bar that is provided to extend toward the destination where the slider advances when the slider is opened with respect to the slider that is movably held along the slider, and the interlock when the shoji is between fully closed and fully open And a stopper device capable of pressing the stopper member toward the side surface of the bar.

The stopper device may have a vibration damping portion that abuts the side surface of the interlocking bar that moves integrally with the slider or that is close to the interlocking bar via a minute gap.
It is preferable that the interlocking bar is formed with a fistula for fitting a tip of the stopper member when the stopper device presses the stopper member.
The stopper device has a release operation part that moves the stopper member pressed against the interlocking bar in a direction away from the interlocking bar, and the release operation part is in front of the shoji when fully closed. It can be arranged on the side.

  The opening setting device for the sliding window according to the present invention is capable of holding the opening of the shoji at an intermediate position between the fully open position and the fully closed position. The operation for releasing the state can be performed very smoothly and easily, and troubles such as breakage can be prevented in advance against the outward pulling action generated in the shoji.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 to FIG. 8 show an embodiment of a window opening degree setting device 1 (hereinafter referred to as “the device 1 of the present invention”) according to the present invention. In this embodiment, as is clear from FIG. 2A, the shoji 3 (a face material, which is a face material and is shown in the example in the figure) held open from the window frame 2 in a cantilevered state with the right hand opening. In this example, the device 1 of the present invention is applied to an opening / closing device 4 for swinging and opening the shoji 3.

As is apparent from FIG. 2B, the opening / closing device 4 and the device 1 of the present invention have a vertical gap between the lower frame upper surface of the window frame 2 and the upper upper surface of the shoji 3, and the upper surface of the lower frame of the window frame 2 and the shoji. 3 are provided at two locations above and below the lower surface of the lower collar.
The upper and lower opening and closing devices 4 and 4 and the upper and lower inventive devices 1 and 1 are configured to have parts shapes and arrangements that are vertically symmetrical with each other, but open and close the shoji 3 with respect to the window frame 2. The operation is the same except that it is vertically symmetric. Therefore, hereinafter, the opening / closing device 4 and the device 1 of the present invention (see FIG. 1) disposed on the lower side will be described.

  First, the opening / closing device 4 will be described. As shown in FIG. 3 and FIG. 4, the opening / closing device 4 is substantially the same in the longitudinal direction of the upper and lower frames of the window frame 2 (the left and right directions when the shoji 3 is fully closed and directly facing the shoji 3. ) Along the slider 10, which is movable along the slider 10, the operating cam 11 that is linked to the slider 10 so as to be swingable horizontally, and the link that is connected to the operating cam 11 so as to be swingable horizontally. A shoji arm 12, a main arm 13 that is link-joined in a horizontally swingable manner so that one end is a ground side (window frame 2 side) and the other end is a shoji arm 12, and one end is a main arm. 13 and an auxiliary arm 14 which is linked to the other end portion of the operating cam 11 so as to be horizontally swingable.

  As described above, the operating cam 11, the shoji side arm 12, the main arm 13, and the auxiliary arm 14 constitute a four-bar linkage mechanism, and the ground side fulcrum 17 of the main arm 13 is a [stationary point], and the shoji side that swings. The arm 12 is set as a [driving node], and the slider 10 provided at or near the link joint between the operating cam 11 and the auxiliary arm 14 is moved to the [driven node]. The shoji 3 is attached so as to be parallel to the longitudinal direction of the shoji-side arm 12 using a coupling hole 16 provided in the shoji-side arm 12.

As shown in FIG. 2 (b), the shoji 3 can be easily opened and closed at a position inside the shoji 3 and on the opposite side in the left-right direction from the position of the opening / closing device 4. A handle 20 is provided.
In short, the shoji 3 is in a state in which the shoji side arm 12 and the actuating cam 11 are link-joined so that the shoji 3 is swingably supported using the swing support point 18. However, the shoji arm 12 is constrained so as not to deviate from the range in which the main arm 13 swings around the grounding fulcrum 17 (is in a moored state). Therefore, when the shoji 3 is pushed outward from the fully closed state (see FIG. 2), the more the shoji side arm 12 is swung, the more the rocking fulcrum 18 of the shoji side arm 12 is on the ground side of the main arm 13. A phenomenon of being drawn to the fulcrum 17 occurs. As a result, the force propagates from the operating cam 11 to the slider 10, and the slider 10 moves in a direction approaching the ground side fulcrum 17 of the main arm 13.

  As a matter of course, when the shoji 3 is stopped or fully opened at the intermediate position, the shoji-side arm 12 swings when the shoji 3 is pulled toward the front (inside) and closed. The phenomenon occurs that the swinging fulcrum 18 of the shoji arm 12 is pushed out of the grounding fulcrum 17 of the main arm 13. As a result, the force propagates from the operating cam 11 to the slider 10, and the slider 10 moves in a direction away from the ground side fulcrum 17 of the main arm 13.

Thus, as the shoji 3 swings and opens and closes, the slider 10 moves the swing fulcrum 18 of the shoji 3 in the upper and lower frame directions (left and right directions) according to the opening of the shoji 3. To do.
The opening / closing device 4 has a base member 23 having a length that supports the moving range of the slider 10 over its entire length, and the base member 23 has a guide rail member for guiding the movement of the slider 10. 24 and a negative pressure receiving member 25 for ensuring the stop state of the slider 10 at the end position of the guide rail member 24 are provided. Further, the grounding side fulcrum 17 of the main arm 13 is held immovably by the base member 23.

The guide rail member 24 is erected along the long side portion on one side of the base member 23, and a flange member is provided on the upper end of the guide member 24 so as to protrude upward from the slider 10. It is formed in an inverted L shape.
The negative pressure receiving member 25 is engaged so as to suppress a part of the upper surface of the slider 10 when the shoji 3 is fully closed. When the shoji 3 receives a negative pressure, the slider 10 is lifted or rattled. This is to prevent this.

The device 1 of the present invention is an interlocking bar provided for the slider 10 provided in the opening / closing device 4 having such a configuration (which is not limited to the detailed structure but refers to a basic configuration for opening and closing the shoji 3). 27 and a stopper device 28 provided on the window frame 2 side so as to correspond to the side surface of the interlocking bar 27.
The interlocking bar 27 is provided so as to extend toward a destination where the slider 10 advances (corresponding to the left in FIG. 3) when the slider 10 moves when the shoji 3 is opened. A material for forming the interlocking bar 27 is not particularly limited. For example, the interlocking bar 27 is formed of a hard band plate made of a metal having a narrow band width (such as iron or stainless steel) and has strong resistance to bending. It can be said that it is preferable.

  The interlocking bar 27 is provided with a plurality of fistulas 30 in the region passing through the stopper device 28 (corresponding to the stroke of the slider 10) while being spaced apart from each other along the bar longitudinal direction. The positions and the number of the fistulas 30 are set according to the opening degree and the number of stops where the shoji 3 is to be stopped in the middle. These holes 30 penetrate the interlocking bar 27 in the inner and outer direction (front-rear direction) in the window frame 2.

The stopper device 28 is disposed at a position beyond the ground side fulcrum 17 of the main arm 13 when viewed from the slider 10. Therefore, when the slider 10 moves to the left and right as the shoji 3 is opened and closed, the interlocking bar 27 is caused to reciprocate through the stopper device 28.
As shown in FIGS. 5 and 6, the stopper device 28 has a configuration in which a square cylindrical stopper case 33 is mounted with a bracket member 32 as an underlay. A stopper member 43 (see FIG. 7 and FIG. 8) described later is loaded in the stopper case 33. Further, the stopper device 28 is provided with a release operation portion 34 that protrudes upward through the upper surface of the stopper case 33.

The bracket member 32 includes a mounting base 35 that is used to insert a mounting screw 38 when the bracket member 32 is mounted on the window frame 2 and the like, a vibration control unit 36 that rises in a wall shape so as to embrace a passing portion of the interlocking bar 27, and this control member. It has a cover part 37 that extends in the horizontal direction so as to cover the upper surface of the interlocking bar 27 from the vibration part 36.
On the other hand, the stopper case 33 is arranged in a direction in which the rectangular tube axis is perpendicular to the passing direction of the interlocking bar 27 (the same as the longitudinal direction of the bar), and is shown in FIGS. Thus, the end on the side facing the interlocking bar 27 is opened, and the end on the opposite side is closed by the spring receiving wall 41. In the present embodiment, the ceiling portion projects in an overhang shape at the open end of the stopper case 33 as compared with the lower surface portion, and the projecting ceiling portion covers the upper portion of the interlocking bar 27. It is.

The stopper case 33 is fixed to the window frame 2 and the like together with the bracket member 32 when the bracket member 32 is fixed to the window frame 2 and the like by the attachment screws 38.
In the present embodiment, the bracket member 32 and the stopper case 33 are both illustrated as being formed by bending a metal plate material. However, the present invention is not limited to this, and a metal material (iron, aluminum, brass, etc.) is used. A casting product may be used, or a plurality of parts may be assembled by welding or screwing.

The stopper case 33 is loaded with a coil spring 42 that is held against the spring receiving wall 41 and a stopper member 43 that is urged by the coil spring 42 so as to be pushed out from the open end of the stopper case 33.
The stopper member 43 includes a sliding body portion 45 having a shape that can slide freely within the stopper case 33, and a rod-shaped flange 46 that integrally projects from the sliding body portion 45 toward the interlocking bar 27. Have. A round bar or a square bar may be used for the rod 46, but depending on the case, a hollow material such as a pipe or a strip material such as L-type, C-type, and H-type may be used.

  The sliding member portion 45 of the stopper member 43 is provided with a driven shaft 47 that penetrates the ceiling portion of the stopper case 33 and protrudes upward. The driven shaft 47 has a disk at a portion that penetrates the stopper case 33. A cam follower 48 is attached. In the ceiling portion of the stopper case 33, a long hole 49 whose longitudinal direction is aligned with the cylindrical axis direction of the stopper case 33 is formed in a portion through which the driven shaft 47 passes (see FIGS. 5 and 6).

Therefore, the driven shaft 47 and the cam follower 48 are movable along the cylinder axis direction of the stopper case 33. The stopper member 43 (sliding body) is moved in the stopper case 33 along with the movement of the driven shaft 47 and the cam follower 48. The part 45 and the flange 46) are also movable.
Since the stopper member 43 receives the urging force of the coil spring 42, the stopper member 43 is always provided with an action protruding from the stopper case 33 (an action of advancing toward the side surface of the interlocking bar 27). Accordingly, when the tip of the stopper member 43 (the flange 46) and the hole 30 of the interlocking bar 27 coincide with each other, the tip of the stopper member 43 fits into the hole 30 of the interlocking bar 27, and this state of insertion is determined. Will be maintained. As a result, the interlocking bar 27 is restrained so as not to move.

  The release operation unit 34 includes a cam 52 that is adjacently disposed in contact with or close to a cam follower 48 provided on the stopper case 33, a cam drive shaft 53 that rotates the cam 52, and the cam drive. And an operating lever 54 provided at the upper end of the shaft 53. The cam 52 is a so-called “eccentric cam” in which a cam drive shaft 53 is coupled to a semicircular eccentric position as shown in FIG.

  That is, when the operation lever 54 is rotated by about 90 °, the cam 52 rotates and the degree of contact with the cam follower 48 gradually increases, so that the cam follower 48 is pushed away along the long hole 49. Therefore, as the cam follower 48 moves, the stopper member 43 is also pushed away in the same direction while resisting the spring force of the coil spring 42.

  Such movement of the stopper member 43 in the pushing-out direction causes the stopper member 43 pressed against the interlocking bar 27 to be moved away from the interlocking bar 27. Naturally, when the stopper member 43 is moved in the pushing-out direction in a state where the tip of the stopper member 43 (the flange 46) is fitted in the hole 30 of the interlocking bar 27, the stopper member 43 comes out of the hole 30. . Therefore, the interlocking bar 27 is released to a movable state.

In the present embodiment, a gap for holding the cam 52 is formed between the upper and lower portions of the ceiling portion of the stopper case 33 and the cover portion 37 of the bracket member 32, and the cam 52 is inclined or rattled within the gap. It is made to rotate stably without producing.
Next, in the case where the shoji 3 is pushed open by holding the handle 20 of the shoji 3 from the fully closed state of the shoji 3 shown in FIG. To do.

When the slider 10 starts to move by swinging the shoji 3, the interlocking bar 27 moves together with the slider 10 in the stopper device 28.
In the stopper device 28, the stopper member 43 has a function of protruding from the stopper case 33 by the biasing force of the coil spring 42, so that the hole 30 of the interlocking bar 27 matches the tip of the stopper member 43 (４３ 46). Sometimes, the tip of the stopper member 43 is fitted into the hole 30 of the interlocking bar 27. As a result, the interlocking bar 27 is restrained so as not to move. That is, the shoji 3 is stopped at an intermediate position before reaching the fully open state, and this state is maintained.

  When the opening degree of the shoji 3 is to be further changed to the opening direction (fully open direction) or to return to the fully closed state, the release operation portion 34 of the stopper device 28 is rotated about 90 °. Since the tip of the stopper member 43 is disengaged from the hole 30 of the interlocking bar 27, the interlocking bar 27 and the slider 10 are released to a movable state, and the shoji 3 can be opened and closed again.

  The opening degree and the number of stop points when the shoji 3 is stopped in the middle can correspond to the formation position and the number of formations of the fistulas 30 provided in the interlocking bar 27. For example, when the opening of the shoji 3 is stopped at four locations of 30 °, 45 °, 60 °, and 90 °, the interlocking bar 27 has four or more locations (5 locations including the fully closed position with an opening of 0 °). The fist hole 30 may be formed in the above. It is also possible to set an opening degree exceeding 90 °.

  In the stopper device 28 having such a configuration, the vibration damping portion 36 of the bracket member 32 is disposed so as to be in contact with the side surface of the interlocking bar 27 or close to each other through a minute gap. become. Therefore, the interlocking bar 27 extending from the slider 10 is held in a sandwiched manner between the vibration damping portion 36 of the bracket member 32 and the stopper case 33 in a region passing through the stopper device 28.

As a result, the side bar of the interlocking bar 27 is reliably prevented from largely vibrating back and forth during the movement, and the movement is stabilized and vibration noise (friction noise, rattling noise, etc.) due to the interlocking bar 27 is prevented. Will be achieved.
In this embodiment, the lower surface of the interlocking bar 27 is supported by the mounting base 35 of the bracket member 32 in the stopper device 28, and the overhanging ceiling portion of the stopper case 33 covers the interlocking bar 27. As a result, the interlocking bar 27 is held in a sandwiched manner in the vertical direction. Therefore, the interlocking bar 27 is held in a stable state that does not rattle even in the vertical direction.

In addition, since the interlocking bar 27 is subjected to a vibration damping action due to the four sides of the front and rear and the upper and lower sides being surrounded in this way, the vibration damping action can stably hold the horizontal movement of the slider 10 in the opening / closing device 4. Will be derived from As a result, the stable movement of the interlocking bar 27 and the slider 10 also stabilizes the opening / closing operation of the shoji 3.
In addition, if the opening / closing device 4 (the slider 10 that moves left and right as the shoji 3 is opened / closed), the passing position of the stopper device 28 by the interlocking bar 27 can be regarded as one support point, the slider 10 This is the same as moving left and right while maintaining a two-point support state together with its own support by the guide rail member 24, which leads to prevention of the slider 10 from being twisted and the like. It can also be said that it has been.

Further, the stopper device 28 inevitably has a release operation portion 34 disposed on the near side (inside) of the shoji 3 when fully closed (FIGS. 3 and 4). , FIG. 7, FIG. 8 etc.). Therefore, it is possible to obtain an advantage that the operator who operates the release operation unit 34 does not cause finger jamming between the shoji 3 to be fully closed and the window frame 2.
Further, the release operation unit 34 is arranged so as to be as close as possible to the opening / closing device 4 when viewed from the handle 20 (see FIG. 2B) provided on the shoji 3, so that the operator Since the handle 20 and the release operation part 34 can be operated with both hands in a natural manner, this also leads to the advantage of improved operability.

As described above, the device 1 of the present invention releases the stop state to the intermediate position as well as the opening / closing operation of the shoji 3 in order to maintain the opening degree of the shoji 3 at the intermediate position between the fully open position and the fully closed position. The operation to be performed can be performed very smoothly and easily, and problems such as breakage can be prevented in advance with respect to the outward pulling action generated in the shoji 3.
In the present embodiment, since the stopper device 28 is configured separately from the base member 23 of the opening / closing device 4 (a separate type), the stopper device 28 can be replaced by itself.

By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.
For example, in the stopper device 28, the stopper member 43 is not limited to be biased by the coil spring 42, and the operation of fitting the tip of the stopper member 43 into the hole 30 of the interlocking bar 27 is also artificial. The structure can be made by operation.

  The stopper member 43 may be configured such that the sliding body portion 45 and the flange 46 are integrally formed. Only the structure in which the tip of the stopper member 43 fits into the hole 30 of the interlocking bar 27 has been described, but the side surface of the interlocking bar 27 is provided with unevenness, and the tip of the stopper member 43 is engaged with the concave portion of the unevenness. A structure that fits together, a structure that presses the side surface of the interlocking bar 27 with the tip of the stopper member 43, and the like can also be employed. In these cases, naturally, it is not necessary to provide the fistula 30 on the side surface of the interlocking bar 27.

  In the opening / closing device 4, the detailed structure such as the four-bar linkage mechanism is not limited to the illustrated one, and can be changed as appropriate. In short, what is necessary is just to have a configuration in which the slider 10 moves left and right as the shoji 3 opens and closes.
