Description

The present invention relates to a movable partition wall used in an office or the like.

Conventionally, as this kind of movable partition wall, a ceiling rail attached to the ceiling of a building and a plurality of panels movably suspended and supported on the ceiling rail are provided, and each of the above panels is provided as another. There are known panels that are configured so that they can be placed adjacent to each other in a wall shape by abutting against a panel or a building wall (see, for example, Patent Document 1).
<First issue>
However, in such a configuration, when the first panel is abutted against the wall parting material provided on the building wall, or when the next panel is abutted against the previous panel installed between the ceiling rail and the floor. A shock is generated at the time. Then, there is a problem that the impact sound is transmitted to the building ceiling via the building wall and the ceiling rail, and is also transmitted to the upper, lower floors, other rooms, and the like.
<Second task>
The above problems are particularly remarkable in a panel provided with a one-touch sealing mechanism.

Japanese Unexamined Patent Publication No. 9-217546

The invention according to claim 1 aims to solve at least the first problem.

The invention according to claim 2 aims to solve not only the first problem but also the second problem.

That is, as a result of exploring why the impact sound is particularly remarkable in the one-touch seal type movable partition wall, the present inventors have found the following facts. In the one-touch seal mechanism, upper skirting boards and lower skirting boards are provided on the upper and lower edges of the panel body so as to be recessed in the front-rear direction and the vertical direction, respectively, and the upper and lower skirting boards are provided by a built-in spring. It is held in a posture in which it protrudes forward by a certain distance in a state of being elastically urged forward. Then, when the panel is brought into contact with the parting material of the building wall or another panel installed earlier, it receives a reaction from the parting material or the like that the upper and lower skirting boards come into contact with, and is relative to the panel body. The upper and lower skirting boards are projected outward by utilizing the immersive operation, and are finally pressed against the ceiling rail and the floor.

However, in the case of the one equipped with such a one-touch seal mechanism, in the operation process in which the upper and lower skirting boards are pushed from the protruding position to the immersion position, the operator strongly resists the repulsive force of the built-in spring only in the first half operating area. It is necessary to push the main body forward. Therefore, we have found that the panel body tends to collide with the wall parting material or other installed panels while maintaining the momentum, and the impact sound at the time of collision becomes loud. The invention according to claim 2 has been made based on the results of such investigation.

That is, the present invention has the following configuration.

The movable partition wall according to claim 1 comprises a ceiling rail attached to the ceiling of a building and a plurality of panels movably suspended and supported on the ceiling rail, and each of the panels is provided.

Further, a tight seal rubber 81 that is in sliding contact with the inner surface of the skirting board storage member 43 of the horizontal frame 11 is attached near the extending end of the side wall 77, and the skirting board 7 moves in the front-rear direction and the left-right direction. However, the tight seal rubber 81 is always in sliding contact with the baseboard storage member 43.

As shown in FIGS. 7 to 10 and 17 to 19, the one-touch seal mechanism 8 has a fixed-side link base 83 provided on the inner wall 45 of the upper and lower horizontal frame main bodies 41, and the upper and lower widths thereof. The movable side link base 85 provided on the outer wall 75 of the wooden body 71 and the fixed side link base 83 support the base end side via the base end pin 87, and the tip end of the movable side link base 85. It is provided with a link arm 91 whose portion is pivotally supported via a tip pin 89, and a torsion coil spring 93 which is an urging means provided between the link bases 83 and 85. The link base 83 on the fixed side is fixed to the inner wall 45 of the horizontal frame main body 41 and arranged in the horizontal frame main body 41. The link base 85 on the movable side is anchored to the outer wall 75 of the skirting board main body 71 and arranged in the skirting board 7. The link arm 91 has an elongated hole 91a at the proximal end portion, and the proximal end pin 87 is inserted into the elongated hole so as to be rotatable and slidable. Both ends of the base end pin 87 are supported by the link base 83 on the fixed side. Further, the tip portion of the link arm 91 is connected to the link base 85 on the movable side via the tip pin 89 in a state where only rotation is permitted. One end of the torsion coil spring 93 is connected to the base end pin 87, and the other end is connected to an action pin 95 provided on the movable link base 85. The action pin 95 moves according to the movement of the baseboard 7 and changes the direction of the urging force of the torsion coil spring 93. That is, as shown in FIGS. 7, 8 and 17, the action pin 95 is displaced forward with respect to the virtual surface connecting the axial center of the tip pin 89 and the axial center of the proximal pin 87. Then, the urging force of the torsion coil spring 93 acts to push the skirting board 7 forward with respect to the panel body 6. Then, the skirting board 7 is pushed by the wall parting members 2, 3 or another standard panel 4 and moves backward, that is, in a direction of being immersed in the panel body 6, and as shown in FIG. 18, the axial center of the action pin 95 is said. When it reaches the virtual surface, the skirting board 7 is not urged either forward or backward by the torsion coil spring 93. When the action pin 95 is displaced rearward with respect to the virtual surface as shown in FIG. 19 beyond such a thought point, the urging force of the torsion coil spring 93 rearwards the baseboard 7 with respect to the panel body 6. The skirting board 7 is designed to maintain an immersive state. In this immersive state, as shown in FIGS. 9 and 19, the skirting board 7 is pressed against the ceiling rails 1a to 1c and the floor F by the urging force of the torsion coil spring 93. That is, the sealing by the skirting board 7 is completed with one touch only by moving the standard panel 4 forward and colliding it with the wall parting members 2, 3 or another standard panel 4. In order to return from the installed state to the released state, an operation of pulling the panel main body 6 backward may be added. That is, when a rearward operating force is applied to the panel body 6, the skirting boards 7 restrained by the ceiling rails 1a to 1c and the floor F are urged forward relative to the panel body 6. As a result, the baseboard 7 automatically returns to the released state in which the baseboard 7 protrudes forward from the panel body 6 through an operation opposite to the operation described above.

Then, in this embodiment, each standard panel 4 is provided with an absorber 9 for absorbing the impact at the time of collision, in other words, for softening the impact sound at the time of installing the standard panel 4. That is, the absorber base 97 is attached to the inner wall 45 of the horizontal frame main body 41 in each standard panel 4, and the absorber 9 is attached to the absorber base 97.

As shown in FIGS. 6 to 16, the absorber base 97 is attached to the front end portion of the inner wall 45 of the horizontal frame main body 41, and is a bottomed cylindrical base main body 97a and the base main body 97a. It is equipped with mounting collars 97b provided on both sides. That is, the absorber 9 is attached to the horizontal frame 11 by fastening the mounting collar 97b to the inner wall 45 with a screw in a posture in which the open end of the base body 97a faces the front vertical frame 19. There is. Through holes 25x and 27x for mounting the absorber 9 on the base body 97a are formed in the outer wall 25 and the inner wall 27 of the vertical frame 19 corresponding to the absorber base 97.

As shown in FIGS. 6 to 16, the absorber 9 is held by the absorber main body 98 supported by the standard panel 4 and the absorber main body 98 so as to be retractable and resists the pressing force at the time of abutting. It is provided with an actuator 99 that performs an immersive operation in the absorber main body 98, and has a configuration called a damper or the like. Generally speaking, the absorber main body 98 has a cylinder shape and holds the piston rod-shaped actuator 99 so as to be retractable. Inside the absorber body 98, for example, an incompressible fluid (not shown) that flows in response to the retracting operation of the actuator 99 is sealed, and a flow path resistance generating element such as an orifice (not shown) is sealed in the flow path of the fluid. The immersive operation of the actuator 99 is suppressed by interposing the actuator 99. To return the immersive actuator 99 to its original protruding position, the repulsive force of the compressible fluid stored in the accumulator (not shown) due to the flow of the incompressible fluid or a mechanical spring (not shown) arranged in the absorber body 98. I try to use. The absorber body 98 has an outer shape that fits into the absorber base 97, and is inserted into and removed from the outside of the panel body 6 through the through holes 25x and 27x provided in the front vertical frame 19. It has become possible. When the absorber body 98 is attached to the absorber base 97, the tip end side of the actuator 99 protrudes outward from the front vertical frame 19. A tip cap 99a is provided at the tip of the actuator 99.

The telescope panel 5 is pulled out between the standard panel 4 and the rear wall parting member 3 after all the standard panels 4 are pulled out below the main ceiling rail 1a, and is at the end. It has an initial width smaller than the separation distance between the vertical frame 21 behind the standard panel 4 and the wall parting member 3 on the rear side. That is, the telescope panel 5 includes a panel main body suspended and supported by the ceiling rail, upper and lower baseboards provided so as to be recessable at the upper and lower ends of the panel main body, and the panel main body. It is equipped with a side skirting board that can be recessed on one side. The telescope panel 5 can be moved along the ceiling rails 1a to 1c with the upper skirting board, the lower skirting board and the side skirting board immersed in the panel body, and is pulled out under the main ceiling rail 1a. At this stage, the upper skirting board, the lower skirting board and the side skirting board are projected from the panel main body and installed flush with the standard panel 4. That is, by projecting the side skirting board while being pulled out under the main rail, the front end side of the telescope panel is pressed against the rear end of the rearmost standard panel, and the side skirting board is pressed against the rear wall. It is pressed against the parting material 3. In this state, the upper skirting board and the lower skirting board are projected from the panel main body and pressed against the ceiling rail and the floor F to complete the installation. Since the internal structure of the telescope panel 5 is irrelevant to the present invention, description thereof will be omitted.

Next, the operation of the movable partition wall W will be described.

Since the entire panel installation procedure is as described above, the operation of installing the first standard panel 4 and the next standard panel 4 under the main ceiling rail 1a will be described in detail as shown in FIG.

As shown in FIGS. 1, 4, 8 and 11, when the leading standard panel 4 is pulled out under the main ceiling rail 1a, the upper and lower skirting boards 7 of the standard panel 4 are the front ends of the panel body 6. It is in a state of protruding forward from. When the standard panel 4 is advanced from this state and abutted against the wall parting material 2 on the front side, the upper and lower skirting boards 7 move outward while retreating relative to the panel body 6 due to the action of the one-touch sealing mechanism 8. It protrudes and is pressed against the ceiling rail 1a and the floor F, and the installation of the standard panel 4 is completed. That is, when the panel main body 6 is advanced by a forward pressing operation force while the upper and lower skirting boards 7 are protruding from the front end of the panel main body 6, the front ends of the upper and lower skirting boards 7 are first placed on the front wall parting material 2. Will come into contact with. When the panel body 6 is further advanced from this position, the upper and lower skirting boards 7 move relatively rearward with respect to the panel body 6, and the link arm 91 of the one-touch seal mechanism 8 moves the urging force of the torsion coil spring 93. It gradually rotates from the forward leaning posture to the standing posture against the above (this working region is referred to as the first half working region). At the end of this first half operating region, as shown in FIGS. 12 and 18, one end of the torsion coil spring 93 is attached to the axial center of the proximal pin 87 that supports the proximal end side of the link arm 91, and the torsion coil. The axis of the action pin 95 to which the other end of the spring 93 is attached and the axis of the tip pin 89 that pivotally supports the tip side of the link arm 91 are located on the common virtual plane P1 (this). The state is called the state where the thought point is reached). When the thought point is reached, the urging force of the torsion coil spring 93 does not contribute to the rotation of the link arm 91. When the panel body 6 is further advanced from the state where the desired point is reached, the link arm 91 rotates rearward and reaches the final backward leaning posture as shown in FIGS. 9, 13 and 19 (this operating region). Is referred to as the latter half working region). In the latter half operating region, the urging force of the torsion coil spring 93 acts as a force for rotating the link arm 91 rearward. In other words, the upper and lower skirting boards 7 are urged by the torsion coil spring 93 so as to be pulled into the panel body 6. Then, at the end of the latter half operating region, the urging force of the torsion coil spring 93 acts exclusively as a force for pressing the upper and lower skirting boards 7 outward, and the upper and lower skirting boards 7 act as a force to press the upper and lower skirting boards 7 outward. The installation of the standard panel 4 is completed by being pressed against the ceiling rail 1a and the floor F while maintaining the immersive posture. Then, in the first half operating region, the operator strongly presses the panel body 6 against the urging force of the torsion coil spring 93 of the one-touch sealing mechanism 8, but from the state where the thought point is reached, the second half operating region Since the urging force of the torsion coil spring 93 is extinguished at once, the panel body 6 is suddenly accelerated forward and tries to collide with the wall parting material 2 on the front side. However, in this embodiment, the actuator 99 of the absorber 9 provided on the panel main body 6 abuts on the wall parting material 2 as shown in FIGS. 12 and 13 from the vicinity of reaching the thought point to the latter half operating region. More specifically, the tip cap 99a provided at the tip of the actuator 99 comes into contact with the bottomed groove 2x provided at the center of the ridge 2a of the wall parting material 2. Therefore, the forward acceleration in the latter half operating region is suppressed by the absorber 9, and the panel main body 6 can be prevented or suppressed from vigorously colliding with the wall parting material. That is, the absorber 9 functions as a shock absorber for softening the impact sound when the standard panel 4 is installed. As a result, it is possible to effectively suppress the impact of the collision from being transmitted from the panel body 6 to the building ceiling through the ceiling rail. In addition, it is possible to effectively prevent or prevent the impact of the collision from being transmitted to the building wall through the wall parting material.

Even when the front end of the next standard panel 4 is abutted with the rear end of the first standard panel 4, the operation according to the above explanation is performed, and the impact sound due to the abutting between the standard panels 4 is generated by the ceiling rail and the ceiling rail. It can be effectively prevented or suppressed from being transmitted to the building ceiling via the hanging tool. At this time, as shown in FIG. 16, the tip cap 99a is in contact with the bottomed groove 33x provided in the center of the outer wall 33 of the vertical frame 21 afterwards. 14, 15 and 16 show the abutting portion between the standard panels 4, FIG. 14 corresponds to FIG. 11, FIG. 15 corresponds to FIG. 12, and FIG. 16 corresponds to FIG. There is.

The same applies to the collision between the next standard panel 4 and the last standard panel 4.

As described above, the movable partition wall W according to the present embodiment absorbs the impact at the time of collision with each of the standard panels 4 movably suspended and supported by the ceiling rail, in other words, the standard panel. 4 Since an absorber 9 is provided to soften the impact sound at the time of installation, the impact is transmitted from the panel body 6 to the building ceiling through the ceiling rails 1a to 1c, and the impact due to the collision is transmitted to the wall parting material 2, It is possible to effectively suppress the transmission to the building wall through 3.

Further, the standard panel 4 presses the skirting board 7 provided so as to be recessable at the upper and lower ends and the skirting board 7 against the ceiling rail 1a and the floor F by utilizing the butt force at the time of abutting. Since the one-touch sealing mechanism 8 is provided, the standard panel 4 can be installed by a simple operation. Further, as described above, from the state where the thought point is reached to the latter half operating region, the urging force of the torsion coil spring acts in the direction of the standard panel 4 toward the wall parting material 2 or another standard panel 4, but this region. By the function of the absorber 9, it is possible to effectively suppress the generation of an impact due to a collision between the standard panel 4 and the wall parting material 2 or a collision between the standard panels 4.

Further, in the present embodiment, the absorber 9 and the one-touch seal mechanism 8 are attached to the horizontal frame main body 41, and the suspension support portion 13 is further attached to the upper horizontal frame main body 41, so that the frame body 15 The horizontal frame main body 41 receives all the load applied to the horizontal frame body 41. That is, since the member to which the absorber 9 is attached and the member that receives the load applied to the frame body 15 are the same, the effect of providing the absorber 9 can be obtained without changing the configuration of the other members.

The absorber 9 is held in the absorber main body 98 supported by the horizontal frame main body 41 of the standard panel 4 and in the absorber main body 98 so as to be sunk and held against the pressing force at the time of abutting. Since the actuator 99 is provided with an immersive operation, the actuator 99 has priority when the standard panel 4 collides with the wall parting material 2 or another standard panel 4 when the standard panel 4 is installed. It is possible to realize a configuration in which the absorber 9 functions by hitting the wall parting material 2 or another standard panel 4.

The upper and lower vertical frames 19 and 21 in which the panel main body 6 is arranged on the front end side and the rear end side in the moving direction and the upper and lower ends of the vertical frames 19 and 21 are connected to each other. The absorber 9 is provided with a frame 11, and the absorber 9 holds the absorber body 98 on an absorber base 97 provided on the horizontal frame 11, and the tip of the actuator 99 is moved from the front vertical frame 19. The above-mentioned effect can be easily obtained by a simple configuration by attaching the panel body 6 to the panel body 6 so as to project outward.

Since the absorber 9 is configured to be removable from the outside of the panel body 6 with respect to the absorber base 97, an assembly procedure for attaching the absorber 9 after assembling the panel body 6 can be adopted. ..

The present invention is not limited to the embodiment described in detail above.

For example, it is not provided with a skirting board provided at the upper and lower ends so as to be recessable, and a one-touch sealing mechanism for pressing the skirting board against the ceiling rail and the floor by utilizing the butt force at the time of abutting. Even if it is a movable partition wall using a panel, the panel is suspended and supported by a ceiling rail, and at least one of the panels is provided with an absorber for absorbing the impact at the time of collision. If there is, at least it is possible to suppress a problem that the impact at the time of the panel-to-panel or the panel-wall parting material is transmitted to the upper, lower floors, other rooms, etc. via the ceiling rail.

Further, in the above-described embodiment, as described above, all the load-bearing members such as the absorber, the one-touch seal mechanism, and the suspension support portion are attached to the horizontal frame main body, and the above-mentioned effects are obtained without changing the design other than the horizontal frame main body. However, it is of course possible to adopt a configuration in which the absorber is attached to a member other than the horizontal frame. In this case, it is preferable to firmly connect the member provided with the one-touch seal mechanism or the suspension support portion and the member provided with the absorber.

The absorber of the above-described embodiment includes an absorber main body supported by a panel and an actuator that is held in the absorber main body so as to be sunk and immerses itself in the absorber main body while resisting a pressing force at the time of abutting. Of course, an absorber having an arbitrary configuration other than this may be adopted.

Then, in the above-mentioned absorber having the absorber main body and the actuator, the absorber main body is held by the absorber base provided on the horizontal frame, and the tip of the actuator is projected outward from the previous vertical frame. Of course, other mounting modes other than mounting on the panel body in the state may be adopted.

In addition, the specific configuration of each unit is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
