Description

  The present invention relates to a moving partition device that partitions a space by moving a panel along a rail fixed to a ceiling.

  Large spaces such as offices, hotels, wedding halls, stores, schools, public facilities, gymnasiums, etc. are used as they are depending on the number of people and purpose of use, etc. Or used as a space. As described above, the moving partition device is used as one that can change the size and shape of the room according to the situation. The moving partition device is configured such that a panel is suspended and supported by a runner that moves in a rail fixed to a ceiling. The panel is moved by a person holding the panel, pushing and pulling it, and applying a driving force in the moving direction to the panel. By applying a driving force to the panel, the runner moves along the rail, so that the panel can be moved to a desired position along the rail.

  When such a panel moving operation is performed, the runner may come into contact with the rail and an impact sound may be generated. In order to prevent this, an elastic roller is fitted on a suspension bolt that suspends and supports the panel on the runner, and the outer dimension of this elastic roller is sized so as to leave a slight clearance between the rail guide portion. It is known (see Patent Document 1). With such a configuration, the runner does not hit the rail in a state where the elastic roller hits the corner of the guide portion at the crossing portion of the rail, thereby suppressing the generation of impact sound.

  Further, there is also known a structure in which a spacer that is prevented from coming off from the rail by functioning as a cushioning material by expanding in the rail and closely contacting the inner wall surface of the rail is known (see Patent Document 2). This spacer has compression deformability, resilience, and indolence, and when the runner collides, the rebound force of the runner collides with the insufficiency of the resilience against the impact, thereby buffering.

JP 2007-262858 A Japanese Patent Laid-Open No. 10-82245

  By the way, in the thing of patent document 1, there is only a slight clearance between an elastic roller and the guide part of a rail. On the other hand, when the panel moves along the rail, in most cases, the panel moves while slightly swinging from side to side, so that the elastic roller moves while occasionally contacting the guide portion. Due to the friction generated by this contact, there is a problem that the operation load when moving the panel tends to be heavy.

  Moreover, in the thing of patent document 2, since the spacer expand | swells within a rail and is closely_contact | adhered to the inner wall of a rail and is prevented from detaching, the spacer has blocked the inside of a rail. As a result, the runner cannot pass through the portion of the rail where the spacer is attached, and there is a problem that the spacer can only be attached to the end of the rail.

  Therefore, the present invention has been made in view of such a problem, and the object of the present invention is to move the panel so that the operation load is light and the cushioning material can be easily attached to a desired position. The object is to provide a partition device.

  In order to solve the above-described problems, according to the present invention, in a moving partition device in which a runner that moves along a rail supported by a ceiling suspends and supports a panel, an inner wall surface of the rail has a moving direction of the runner. A buffer partition that penetrates the wall portion of the rail is provided at a position that intersects with the extension line, and a moving partition device that constitutes a contact surface with which the runner contacts is provided.

  According to this invention, since the cushioning material penetrates the wall portion of the rail, the thickness dimension of the cushioning material becomes a size obtained by adding the protruding amount from the inner wall surface to the thickness dimension of the rail wall portion. For this reason, the shock-absorbing material has a thickness dimension sufficient to alleviate the impact at the time of contact with the runner, but the amount of protrusion inside the rail is suppressed.

  Moreover, since the buffer material penetrates the wall portion of the rail, the position of the buffer material can be defined. Thereby, positioning of a shock absorbing material can be made accurate.

  Furthermore, if the clearance between the inner wall surface of the rail and the runner is large, the runner will roll and cause the panel to swing greatly. In particular, a panel having a large height is dangerous because the swing width increases. Therefore, the clearance between the inner wall surface of the rail and the runner is set to be small, but the amount of protrusion of the cushioning material inside the rail is suppressed, so that it is arranged at a position that intersects with the extended line in the movement direction of the runner. The runner abuts against the cushioning material that is present, but does not intersect the extension line of the movement direction of the runner, that is, the runner abuts against the cushioning material that is disposed substantially in parallel, that is, it does not easily interfere. Yes. For this reason, it is difficult for the cushioning material to obstruct the moving runner, and the occurrence of troubles such as a heavy operation load on the panel is prevented.

  In addition, for example, in the case where the rail is branched or bent, the runner may come into contact with the branch portion or the bent portion when the runner moves from one rail to the other branched or bent rail. Many. For this reason, by providing a buffer material in the branch part or bending part of a rail, when a runner changes a moving direction in a branch part or a bending part, it will collide with a buffer material. Thereby, the impact at the time of a runner colliding with a rail is relieved.

  In addition, one end side of the buffer material is fixed to the plate, and the plate is fixed to the outer wall surface of the rail, so that the other end of the buffer material protrudes from the inner wall surface of the rail so as to constitute a contact surface. Also good. Thus, the cushioning material is not attached from the inside of the rail in a limited space within the rail, but is attached from the outside of the rail, so that the cushioning material can be easily attached to the rail.

  Further, according to the present invention, in the moving partition device in which the runner moving along the rail supported by the ceiling suspends and supports the panel, at the position where the runner crosses the extension line in the moving direction of the runner on the inner wall surface of the rail, One end of a cushioning material provided in a recess formed in the wall portion of the rail is projected from the recess to provide a moving partition device that constitutes a contact surface with which the runner contacts.

  According to this invention, since the cushioning material is inserted into the recess of the rail, the thickness dimension of the cushioning material becomes a size obtained by adding the protrusion amount from the inner wall surface to the depth dimension of the recess of the rail. For this reason, the shock-absorbing material has a thickness dimension sufficient to alleviate the impact at the time of contact with the runner, but the amount of protrusion inside the rail is suppressed.

  Further, since the position of the cushioning material can be defined by the recess formed in the rail, the positioning of the cushioning material can be made accurate.

  Furthermore, if the clearance between the inner wall surface of the rail and the runner is large, the runner will roll and cause the panel to swing greatly. In particular, a panel having a large height is dangerous because the swing width increases. Therefore, the clearance between the inner wall surface of the rail and the runner is set to be small, but the amount of protrusion of the cushioning material inside the rail is suppressed, so that it is arranged at a position that intersects with the extended line in the movement direction of the runner. The runner abuts against the cushioning material that is present, but does not intersect the extension line of the movement direction of the runner, that is, the runner abuts against the cushioning material that is disposed substantially in parallel, that is, it does not easily interfere. Yes. For this reason, it is difficult for the cushioning material to obstruct the moving runner, and the occurrence of troubles such as a heavy operation load on the panel is prevented.

  In addition, for example, in the case where the rail is branched or bent, the runner may come into contact with the branch portion or the bent portion when the runner moves from one rail to the other branched or bent rail. Many. For this reason, by providing a buffer material in the branch part or bending part of a rail, when a runner changes a moving direction in a branch part or a bending part, it will collide with a buffer material. Thereby, the impact at the time of a runner colliding with a rail is relieved.

According to the present invention, since the cushioning material is provided in the concave portion formed through or through the wall portion of the rail, the thickness dimension of the cushioning material is equal to the thickness dimension of the rail wall portion or the depth dimension of the concave portion. It becomes the size which added the amount of protrusion from the wall surface. For this reason, the shock-absorbing material has a thickness dimension sufficient to alleviate the impact at the time of contact with the runner, but the amount of protrusion inside the rail is suppressed. For this reason, when the runner abuts against the shock absorbing material, the shock absorbing material can alleviate the impact caused by the abutting. In addition, since the amount of protrusion of the cushioning material is small, the cushioning material in a position substantially parallel to the direction of movement of the runner is less likely to interfere with the runner, preventing occurrence of obstacles such as heavy operation load on the panel. The
The other effects of the present invention will be described in the section for carrying out the invention below.

  The configuration of the moving partition device according to the first embodiment of the present invention will be described with reference to FIG. The moving partition device 100 according to the present embodiment includes a rail 110 fixed to a ceiling (not shown), a runner 120 that moves in the rail 110, a panel 130 that is suspended and supported by the runner 120, The front end 141 protrudes from the wall surface 112a into the internal space 111 of the rail 110, and when the runner 120 comes into contact, the shock absorber 140 that cushions the shock and the other end of the shock absorber 140 are supported and the outer wall surface 112b of the rail 110 is supported. And a fixed plate 150 to be fixed. Hereinafter, each structure of the movement partition apparatus 100 is demonstrated in detail.

(Rail 110)
The rail 110 includes a plurality of rail parts 110a, 110b. . . Are connected in a T-shape or L-shape. These rail parts 110a, 110b. . . The arrangement position of the panel 130, that is, the size and shape of the space partitioned by the panel 130 is determined by the arrangement of. As shown in FIG. 1, the internal space 111 of the rail 110 is divided into two upper and lower stages by ribs 113, 113 protruding from both wall portions 112, 112 of the rail 110. As shown in FIG. 2, notches 114 and 114 are respectively formed on the branch portion of the rail 110 configured in a T shape and the wall 112 on the outer peripheral side in the vicinity of the bent portion of the rail 110 configured in an L shape. Is formed. When the runner 120 is disposed on the rail 110, the notches 114 and 114 are respectively provided at positions of an upper space 111a and a lower space 111b corresponding to rollers 122 and 122 of the runner 120 described later. In the case of a T-shaped branch, the notches 114 and 114 are formed in the wall 112 of the other rail part 110b facing the internal space 111 of the one rail part 110a. On the other hand, in the case of an L-shaped bent portion, it is formed on each of the outer peripheral wall portions 112 and 112 sandwiching the bent portions of the two rail parts 110a and 110b constituting the L shape. In addition, a female screw hole (not shown) is formed around the notches 114 and 114 for screwing a later-described screw 151 in order to fix the fixing plate 150 to the rail 110.

(Runner 120)
As shown in FIG. 1, the runner 120 includes a pair of rollers 122 and 122 that are rotatably provided in a vertical direction on a support shaft 121. The support shaft 121 has a screw part 121a on the lower side, and a nut 123 with a spring washer is screwed to the screw part 121a. The pair of rollers 122 and 122 are respectively disposed in the upper space 111 a and the lower space 111 b of the rail 110, and are movable along the rail 110.

(Panel 130)
The panel 130 is suspended by a pair of runners 120, and the upper end portions in the vicinity of both ends in the longitudinal direction of the panel 130 are connected to the support shaft 121 of the runner 120 by nuts 123 with spring washers. Accordingly, the panel 130 is suspended from the rail 110 so as to be movable.

(Buffer material 140)
The cushioning material 140 has a thin columnar shape and is sized to fit into the notch 114 of the rail 110. The thickness dimension of the cushioning material 140 is slightly larger than the thickness dimension of the wall portion 112 of the rail 110, so that when the cushioning material 140 is inserted into the notch 114, the tip 141 of the cushioning material 140 extends from the notch 114 to the rail. It protrudes into the internal space 111 of 110. Further, the buffer material 140 is made of an isobutylene-based material, and when the roller 122 of the runner 120 comes into contact, the shock due to the contact is buffered.

(Fixing plate 150)
The fixing plate 150 has a rectangular shape, and is arranged with respect to the rail 110 so that the longitudinal direction thereof corresponds to the vertical direction of the wall portion 112 of the rail 110. The rear ends 142 of the two cushioning members 140 and 140 are attached to and supported by the fixed plate 150 so as to be juxtaposed in the longitudinal direction thereof. The two cushioning members 140 and 140 attached to the fixing plate 150 are set at positions where they are respectively inserted into the upper and lower cutout portions 114 and 114 of the rail 110 when the fixing plate 150 is attached to the wall portion 112. . In addition, as shown in FIG. 2, the fixing plate 150 is formed with six female screw holes 152 (in FIG. 2, the three female screw holes on the back side of the drawing are hidden and cannot be seen). Yes. These female screw holes 152 are formed at positions where the positions of the female screw holes 152 coincide with the positions of the female screw holes of the rail 110 when the fixing plate 150 is attached to the rail 110.

Next, a method for attaching the cushioning material 140 of this embodiment to the rail 110 will be described.
As shown in FIG. 2, the positions of the two cushioning members 140 and 140 are made to coincide with the positions of the notches 114 and 114 of the rail 110, the fixing plate 150 is disposed outside the rail 110, and the fixing plate 150 is attached to the rail 110. It is made to contact | abut to wall part 112. As a result, as shown in FIG. 3, the tips 141 and 141 of the two cushioning members 140 and 140 are inserted into the notches 114 and 114 of the rail 110 and project into the internal spaces 111 a and 111 b of the rail 110. Thereafter, the screw 151 is screwed into the female screw hole 152 of the fixing plate 150 and then screwed into the female screw hole of the rail 110, whereby the fixing plate 150 is fixed to the rail 110. Thus, the cushioning members 140 and 140 are attached in a state of slightly protruding from the inner wall surface 112a of the rail 110. Since the thickness dimension of the cushioning material 140 has a size obtained by adding the amount protruding from the inner wall surface 112a to the thickness of the wall portion 112 of the rail 110, the shock when the roller 122 of the runner 120 abuts is reduced. On the other hand, it has a sufficient thickness dimension. Thereby, the buffer material 140 can relieve an impact, suppressing the protrusion amount to the internal space 111 of the rail 110.

  The runner 120 is disposed in the internal space 111 of the rail 110 configured as described above. However, if the clearance between the inner wall surface 112a of the rail 110 and the runner 120 is large, the runner 120 rolls and the panel swings greatly. Cause. In particular, a panel having a large height is dangerous because the swing width increases. For this reason, the clearance between the inner wall surface 112a of the rail 110 and the runner 120 is configured to be small. In the buffer material 140 of this embodiment, the amount of protrusion of the rail 110 into the internal space 111 is suppressed, so that the runner 120 that moves even if the clearance between the inner wall surface 112a of the rail 110 and the runner 120 is small. Is difficult to contact.

Next, the state of the runner 120 and the buffer material 140 according to the traveling direction will be described with reference to FIGS. 4 and 5.
When the runner 120 is moving along the rail 110, as shown in FIG. Moving. Thereby, the operation load of the panel 130 does not become heavy.

  On the other hand, when the runner 120 moves from the first rail 110a to the second rail 110b branched or bent in a T shape, the first rail 110a is moved as shown by an arrow A in FIG. The runner 120 is moving toward the inner wall surface 112a of the second rail 110b. When the runner 120 completely enters the second rail 110b, the rollers 122 and 122 of the runner 120 come into contact with the cushioning members 140 and 140 of the second rail 110b, respectively. Thereby, the buffer materials 140 and 140 are deformed, and the impact caused by the contact of the rollers 122 and 122 is reduced. When the rollers 122 and 122 of the runner 120 come into contact with the shock absorbers 140 and 140, the shock absorbers 140 and 140 are pushed. When changing the direction of the runner 120, the traveling direction can be changed while the cushioning materials 140 and 140 are pushed in by the rollers 122 and 122.

Next, a procedure for storing the panel 130 in the storage unit 160 will be described with reference to FIGS.
The rail 110 extends in a substantially T-shape from a long straight first rail 110a, a second rail 110b bent in a substantially L shape with respect to the first rail 110a, and a midway in the longitudinal direction of the second rail 110b. A first storage rail 110c and a second storage rail 110d which is bent in a substantially L shape from the tip position of the second rail 110b and is parallel to the first storage rail 110c are configured. The storage rails 110 c and 110 d are disposed in the storage unit 160. Three panels 130 are already stored in the storage rails 110c and 110d.

A first buffer material 140a and a second buffer material 140b are provided on the wall portion 112 at the end of the bent portion of the first rail 110a and the second rail 110b, respectively, and the first T-shaped first T-shaped. A third cushioning material 140c is provided on the wall 112 of the second rail 110b facing the storage rail 110c. In addition, a fourth cushioning material 140d and a fifth cushioning material 140e are provided on the wall portion 112 at the end of the second rail 110b and the second storage rail 110d on the bent side.

  As shown by the phantom line in FIG. 6, the panel 130 arranged on the first rail 110a is moved in the direction of arrow A in FIG. 6, and as shown by the solid line in FIG. 6, the first rail 110a. Move to the end of Thus, the leading runner 120a in the traveling direction of the panel 130 passes without interfering with the first buffer material 140a of the first rail 110a, and comes into contact with the second buffer material 140b of the second rail 110b from the front.

  Then, the leading runner 120a is moved along the second rail 110b while pushing in the second cushioning material 140b of the second rail 110b. As a result, the panel 130 turns as shown by the phantom line in FIG. When a force is continuously applied in the direction in which the panel 130 is rotated, the leading runner 120a moves along the second rail 110b as shown by an arrow A in FIG. It moves along the rail 110a. As a result, the panel 130 turns as shown by the solid line in FIG. At this time, the leading runner 120a passes without interfering with the third buffer material 140c. Therefore, the course of the leading runner 120a is not changed.

  When the panel 130 is continuously rotated, the leading runner 120a further moves the second rail 110b as shown by the arrow A in FIG. 8, and the rear runner 120b moves the first rail 110a, so that the arrow B in FIG. As shown in FIG. 2, after passing without contacting the first cushioning material 140a, it contacts the second cushioning material 140b. As a result, the panel 130 is completely moved to the second rail 110b. In this way, the rear runner 120b does not interfere with the first cushioning material 140a, so the course of the rear runner 120b is not changed. Therefore, the roller 122 does not collide with the corner formed by the first rail 110a and the second rail 110b. Further, since the second cushioning material 140b is deformed when the roller 122 abuts, the impact caused by the abutment can be reduced.

  Further, as indicated by an arrow A in FIG. 9, the panel 130 is moved to the tip of the second rail 110b until the leading runner 120a contacts the fifth cushioning material 140e. As a result, the position of the leading runner 120a has moved to a position corresponding to the first storage rail 110c, and the position of the subsequent runner 120b has moved to a position corresponding to the second storage rail 110d. During this movement, the leading runner 120a does not interfere with the fourth buffer material 140d, and the subsequent runner 120b does not interfere with the third buffer material 140c. For this reason, since the course of the runner 120 is not changed, the roller 122 does not collide with the corner formed by the second rail 110b and the first storage rails 110c and 110d.

  Finally, when the panel 130 is stored in the storage unit 160, as shown by arrows A and A in FIG. 10, the head runner 120a and the rear runner 120b are translated along the storage rails 110c and 110d. As a result, the panel 130 is stored in the storage unit 160.

  When the panel 130 is pulled out from the storage unit 160, as shown by arrows A and A in FIG. 11, the leading runner 120a and the rear runner 120b are translated along the storage rails 110c and 110d in the direction opposite to that during storage. Let When the first runner 120a and the rear runner 120b come into contact with the third cushioning material 140c and the fourth cushioning material 140d, the panel 130 is completely moved to the second rail 110b and completely pulled out from the storage portion 160. It will be in the state. Thereafter, by moving the panel 130 along the rail 110 and disposing it at a desired position, the space can be partitioned into a desired size and shape.

  As described above, according to the present embodiment, the cushioning material 140 is inserted into the notch 114 of the rail 110, so the thickness dimension of the cushioning material 140 is equal to the thickness dimension of the wall 112 of the rail 110. It becomes the magnitude | size which added the protrusion amount from 112a. For this reason, the cushioning material 140 has a thickness dimension sufficient to alleviate the impact with which the runner 120 abuts, and the amount of protrusion of the rail 110 in the internal space 111 is suppressed.

  Further, the cushioning material 140 is less likely to interfere with the runner 120 moving along the rail 110 because the protruding amount of the rail 110 in the internal space 111 is small. Accordingly, the buffer material 140 does not interfere with the moving runner 120, and the occurrence of trouble such as an increase in the operation load on the panel 130 is prevented.

  Further, by providing the buffer material 140 at the branching portion and the bent portion of the rail 110, the roller 122 does not directly contact the rail 110 when the runner 120 changes the course at the branching portion and the bent portion, but the buffer material. 140 abuts. Thereby, the impact when the runner 120 contacts the rail 110 is reduced.

  Further, the cushioning material 140 is attached not from the inside of the rail 110 but from the outside of the rail 110 in the limited internal space 111 in the rail 110. Furthermore, the buffer material 140 can be attached to the rail 110 by fixing the fixing plate 150 that supports the other end of the buffer material 140 to the outer wall surface 112 b of the rail 110. For this reason, the attachment work to the rail 110 of the shock absorbing material 140 is easy.

  Furthermore, since the position of the buffer material 140 can be defined by the notch 114 formed in the rail 110, the positioning of the buffer material 140 can be made accurate.

(Second Embodiment)
Next, the movement partition device 100 according to the second embodiment will be described with reference to FIG. The present embodiment is characterized by the cushioning material 140 in the moving partition device 100 according to the first embodiment. Here, only the configuration of the cushioning material 140 will be described, and the other parts are the same as those in the first embodiment, and therefore, redundant description is omitted. The configurations of the cushioning material 140 and the notch 114 are the same for both the upper space 111a and the lower space 111b, and therefore will be described without particular distinction.

  As shown in FIG. 12, the cushioning material 140 according to the present embodiment is configured to have a slightly larger diameter than the notch 114 of the rail 110, and the tip 141 passes through the notch 114 from the outer wall 112 b side of the rail 110. The inner space 111 is press-fitted. The tip 141 of the cushioning material 140 slightly protrudes into the internal space 111, and the peripheral edge is in surface contact with the inner wall surface 112a. On the other hand, the rear end 142 protrudes slightly outward from the outer wall surface 112b, and the peripheral edge is in surface contact with the outer wall surface 112b. The portion of the cushioning material 140 that fits into the notch 114 is compressed so as to correspond to the size of the notch 114. Thereby, the buffer material 140 is in a state of being attached to the rail 110 without being detached from the notch 114.

  As described above, according to the present embodiment, since the front end of the cushioning material 140 is only press-fitted into the internal space 111 from the outer wall surface 112b side of the rail 110 via the notch 114, the mounting work is easy. In addition, since the fixing plate 150 is not used and the buffer 110 is fixed to the rail 110 only, the number of parts and the number of manufacturing processes can be reduced.

(Third embodiment)
Next, a movement partition device 100 according to a third embodiment will be described with reference to FIG. The present embodiment is characterized only in the buffer partition 140 and the rail 110 portion to which the buffer material 140 is attached in the moving partition device 100 according to the first embodiment. Here, only the configuration of the cushioning material 140 and the part of the rail 110 to which the cushioning material 140 is attached will be described, and the other parts are the same as those in the first embodiment, and thus the duplicated description is omitted.

  As shown in FIG. 13, the rail 110 according to the present embodiment has a recess 115 formed on the inner wall surface 112 a instead of the notch 114 according to the first embodiment. The recess 115 is formed such that a step portion is formed in the thickness direction of the wall portion 112 of the rail 110 so that the opening on the inner wall surface 112a side is reduced.

  Further, as shown in FIG. 13, the cushioning material 140 of the present embodiment has a hollow rectangular shape, a fitting portion 143 that fits into the recess 115, and a tip that protrudes into the internal space 111. 141. The tip 141 protruding into the internal space 111 is in surface contact with the inner wall surface 112a.

Next, a method for attaching the cushioning material 140 of this embodiment to the rail 110 will be described.
The fitting portion 143 of the cushioning material 140 is fitted and inserted into the concave portion 115 from the end portion of the rail 110, and is slid to the branch portion or the bent portion of the rail 110 with the fitted state. In the bent portion, positioning is performed by bringing the cushioning members 140 inserted from the ends of the different rails 110 into contact with each other.

  Thus, according to the present embodiment, since a part of the cushioning material 140 is inserted into the recess 115 of the rail 110, the thickness dimension of the cushioning material 140 is equal to the thickness dimension of the recess 115 from the inner wall surface 112a. It becomes the size which added the amount of protrusion. For this reason, the cushioning material 140 has a thickness dimension sufficient to alleviate the impact caused by the contact of the runner 120, but the amount of protrusion of the rail 110 in the internal space 111 is suppressed.

  Further, since the amount of protrusion of the buffer material 140 in the internal space 111 of the rail 110 is small, the buffer material 140 does not interfere with the runner 120 moving along the rail 110. Thereby, the buffer material 140 does not interfere with the moving runner 120, and there is no obstacle such as a heavy operation load on the panel 130.

  Further, by providing the buffer material 140 at the branching portion and the bending portion of the rail 110, the roller 122 does not directly contact the rail 110 when the runner 120 changes the moving direction at the branching portion and the bending portion. 140 abuts. Thereby, the impact when the runner 120 contacts the rail 110 is reduced.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. is there.

  In addition, you may provide the buffer material 140 made into the L-shape along the shape of a bending part in the bending part of the rail 110, for example.

  Further, the position where the cushioning material 140 is provided is not limited to the position of the above embodiment as long as the movement of the runner 120 is not restricted.
