Description

The present invention relates to the technical field of tight-fitting structures in panel bodies that constitute panels such as partition panels for dividing indoor spaces.

Generally, panels such as partition panels are installed to separate the interior spaces of buildings, etc., and some of the panel bodies that make up such panels are configured as sliding doors that move left and right to open and close, and are opened and closed by having a running roller (door roller) attached to the lower edge of the panel body guided by a lower guide rail attached to the floor, while a guide body attached to the upper edge is guided by an upper guide rail attached to the ceiling.
However, when such a panel body is in the closed position, a gap is formed between the panel body and the body-side member, which impairs airtightness and sound insulation. Therefore, it has been proposed to provide a sealing material (sealing material, airtight material, sound-insulating material) on the body-side member to prevent this gap. However, when doing so, the panel body slides against the sealing material during the opening and closing movement of the panel body, generating sliding resistance. This not only impairs the smooth opening and closing movement of the panel body, making the opening and closing operation of the panel body difficult, but also accelerates deterioration (wear and tear) of the sealing material due to sliding contact with the panel body, resulting in problems such as the need for earlier replacement.
Therefore, a conventional device that solves the above problem is known in which the panel body moves in an inclined position away from the sealing material when opening and closing, and the panel body is transformed into an upright position in time with the movement to the closed position (see Patent Document 1).

Patent No. 5358279

However, in the above-mentioned conventional system, a guide body attached to the upper edge of the panel body is configured to swing freely in the front-to-rear direction, and guide rollers extending outward from the panel body in the front-to-rear direction are configured to roll relative to roller receivers protruding from the main body member in time with the panel body moving to the closed position, thereby causing the panel body to change position from the inclined position to an upright position and come into close contact with the sealing material. As a result, this system requires separate guide rollers, roller receivers, etc., which not only increases the number of parts but also impairs visibility as they are visible from the outside. Furthermore, the guide body needs to have a special structure that swings back and forth, making it less versatile. These are the issues that this invention aims to solve.

The present invention has been made in view of the above-mentioned circumstances and with the aim of solving these problems, and the invention of claim 1 is a panel body arranged in an opening, which is guided left and right by a lower guide rail on the floor surface side and an upper guide rail on the ceiling side to open and close the opening, wherein at least one of the front and rear surfaces of the panel body is in close contact with a ceiling side frame member provided on the ceiling side via a sealant, and the panel body is provided with a guide body that is guided by the upper guide rail, and the upper guide rail is provided with a release guide section that guides the guide body to a release position in which the close contact via the sealant of the panel body is released during the process of opening and closing the panel body, and a release guide section that guides the guide body when the panel body moves to a closed position. and a contact guide portion that guides the guide body so that the panel body is in a contact position in which it is in contact with the ceiling-side body member via the sealing material in time with the movement of the panel body.The panel body is formed with an extended surface portion that extends upward from one of the surfaces in the front-to-rear direction, and the extended surface portion is in contact with the ceiling-side body member via the first sealing material, while the upper guide rail is configured with a first guide piece portion on the extended surface portion side and a second guide piece portion on the opposite side, which serve as guide surfaces that guide the guide body provided on the panel body as it is inserted from below, and the contact guide portion is formed by bending the portions of the first and second guide pieces that correspond to the contact guide portions on the opposite side to the extended surface portion with respect to the portion that corresponds to the release guide portion.This is a contact structure for a panel body.
The invention of claim 2 is a tightly sealed structure for the panel body according to claim 1 , characterized in that the other surface portion in the front-to-rear direction of the panel body is tightly sealed to the ceiling side body member via a second sealing material.
The invention of claim 3 is a close-contact structure in a panel body described in claim 1, characterized in that a first guide plate is stacked on the inside of the portion of the first guide piece corresponding to the close-contact guide portion to draw and guide the guide body toward the ceiling side body member, thereby forming a guide surface on the extended surface side of the close - contact guide portion.
The invention of claim 4 is a close-contact structure in a panel body described in claim 1 or 3, characterized in that a portion of the second guide piece corresponding to the close-contact guide portion is cut out, and a second guide plate is provided in the cutout portion so as to bend toward the opposite side from the extended surface portion, thereby forming a guide surface on the opposite side from the extended surface portion of the close-contact guide portion.
The invention of claim 5 is a close-fitting structure in a panel body described in claim 4 , which cites claim 3 , characterized in that the first guide plate is set to be narrower than the cutout width of the cutout portion formed in the second guide piece portion.

According to the invention of claim 1, the panel body in the release position, in which the seal is released during the opening and closing movement process, can be easily transformed into the seal position via the seal by providing an upper guide rail for guiding a guide body on the panel body with a seal guide portion for changing the panel body into the seal position relative to the release guide portion that guides the panel body in the release position, thereby achieving excellent airtightness and sound insulation. Furthermore, there is no need to provide a guide member that is visible from the outside, as in the conventional case, thereby suppressing an increase in the number of parts and simplifying the structure by eliminating the need for a special guide body that swings back and forth. Furthermore, the extension surface portion on the panel body is in close contact with the ceiling-side frame member via the first seal material, thereby achieving a sealing structure using the extension surface portion. Furthermore, the upper guide rail has first and second guide pieces, and the portions of the first and second guide pieces corresponding to the seal guide portions are formed by bending them on the opposite side of the extension surface portion relative to the portions corresponding to the release guide portion, thereby simplifying the seal guide portion structure.
By adopting the invention of claim 2 , the other surface portion of the panel body itself in the front-to-rear direction is closely attached to the ceiling side body member via the second sealing material, thereby achieving a sealing structure using the panel body itself.
By adopting the invention of claim 3 , a first guide plate for pulling the guide body toward the ceiling side body member and guiding it is laminated on the inside of the portion corresponding to the close-contact guide portion of the first guide piece, thereby easily creating a guide surface on the extended surface side of the close-contact guide portion.
By adopting the invention of claim 4 , a cutout portion is formed in the portion of the second guide piece corresponding to the close-contact guide portion, and a second guide plate is provided here that bends toward the opposite side from the extended surface portion, making it possible to easily create a guide surface on the opposite side from the extended surface portion of the close-contact guide portion.
By adopting the invention of claim 5 , the first guide plate is narrower than the width of the cutout portion formed in the second guide piece portion, so that the first guide plate can be assembled through the cutout portion, thereby improving workability.

The present invention will be described below with reference to the drawings, in which reference numeral 1 denotes a partition panel for dividing an interior space of a building into front and rear sections, and the partition panel 1 is provided to separate a narrow storage room (machine room, inspection room) R from the interior space S into front and rear sections for storing (storing) various components such as machinery and equipment, devices, and indoor units of air conditioners.
The partition panel 1 of this embodiment is made up of a total of four panel bodies 2, 3 arranged in a series in the left-right direction, of which the two panel bodies 2 on the left and right ends form swing doors that are hinged via hinges 4b to vertical posts 4a attached to vertical frame members (wall-side rails) 4 provided on the wall W so as to open and close toward the interior space R, while the two panel bodies 3 on the left and right center sides form sliding doors that open and close in the left-right direction as will be described later, and correspond to the "panel body" of the present invention. However, as shown in Figure 2, the panel body 3 that forms the sliding door is configured to be able to open and close in the left-right direction while the panel body 2 that forms the swing door is open to the outside of the storage room S (towards the interior space R).
In the following explanation, for convenience, the explanation will be based on the storage room R, and therefore the inside of the storage room R will be referred to as the "inside" or "inside side", and the indoor space S side outside the storage room R will be referred to as the "outside" or "outside side", but it goes without saying that the present invention is not limited to this explanation.

The partition panel 1 is attached to its four peripheral edges by the left and right vertical frame members 4 (vertical supports 4a), as well as an upper frame member (ceiling rail) 5 that hangs down from the ceiling surface H and a lower frame member (floor rail) 6 that stands upright from the floor surface F, forming a four-sided frame. The partition panel 1 is arranged so that its outer periphery is surrounded by the frame members 4 (4a), 5, and 6 that make up the four peripheral frames.

On the other hand, the panel bodies 2, 3 have outer side surfaces 2a, 3a on the outside and inner side surfaces 2b, 3b on the inside as the front and back surfaces, and filler materials 2c, 3c are interposed between these two side surfaces 2a, 2b, 3a, 3b, and the panel main body portions 2e, 3e are formed by being surrounded on all four sides by frame materials 2d, 3d.
The outer surface portions 2a, 3a of the panel bodies 2, 3 are formed with extended surface portions 2f, 3f that extend outward in the vertical direction from the upper and lower end edges of the panel main body portions 2e, 3e, and these extended surface portions 2f, 3f are configured to closely face the outer side surfaces 5a, 6a of the upper and lower frame members 5, 6.By being configured in this manner, the gap between the upper and lower end edges of the panel main body portion 2e and the end edges of the upper and lower frame members 5, 6 is covered from the outside.
Furthermore, in this embodiment, the extended surface portions 2f, 3f have a two-plate structure, inner and outer, of which the outer plates 2g, 3g are flat, while the inner plates 2h, 3h have protrusions 2i, 3i formed in a convex shape facing inward.

Furthermore, left, right and top and bottom frame panel materials 7, 8, 9 are provided on the inner sides of the left and right vertical supports 4a and the top and bottom frame materials 5, 6. In this embodiment, the "body member" is basically composed of the vertical frame material 4 including the vertical support 4a and the top and bottom frame materials 5, 6, but the frame panel materials 7, 8, 9 attached to these frame materials 4, 5, 6 also function as constituent members that make up the "body member".
In this way, the upper and lower frame panel materials 8, 9 are provided on the inner side surfaces of the upper and lower frame materials 5, 6, so that the gap between the upper and lower edge portions of the panel body main body portion 2e and the edge portions of the upper and lower frame materials 5, 6 is covered from the inside.
In addition, the left and right frame panel materials 7 are fastened to the L-shaped mounting brackets 7a attached to the visible surfaces of the left and right vertical posts 4a and to the inner visible surfaces of the vertical posts 4a from the inside, via screws 7b inserted from the outside of the mounting brackets 7a.

In contrast, the upper and lower frame panel materials 8, 9 are attached to the inner sides 5b, 6b of the upper and lower frame materials 5, 6 and are fastened via screws 8a, 9a inserted from the outer sides 5a, 6a of the upper and lower frame materials 5, 6. In this case, however, the screws 8a, 9a penetrate the upper and lower frame materials 5, 6 and are therefore longer than the screws 7b used to fasten the left and right frame panel materials 7.
Furthermore, the screws 8a, 9a are configured so that their heads 8b, 9b fit into the grooves 5c, 6c formed in the outer side surfaces 5a, 6a to fit in the bases 10a, 11a of the upper and lower sealing materials 10, 11 attached to the outer side surfaces 5a, 6a of the upper and lower frame members 5, 6, and abut against the bottom surfaces of the grooves 5c, 6c.The fitted screw heads 8b, 9b are then covered by the bases 10a, 11a of the upper and lower sealing materials 10, 11 fitted into the grooves 5c, 6c.
When the panel bodies 2, 3 are in the closed position, the extended surface portions 2f, 3f (specifically, the protruding portions 2i, 3i) are configured to adhere closely (contact, abut) to the sealing materials 10, 11 to seal the inside and outside.
On the other hand, the left and right frame panel materials 7 are provided with sealants 12 that fit tightly against the inner side surface portions 2b of the panel body 2 in the closed position to seal the inside and outside, and the upper and lower frame panel materials 8 and 9 are provided with second upper and lower sealants 13 and 13a that fit tightly against the inner side surface portions 2b and 3b of the panel bodies 2 and 3 in the closed position to seal the inside and outside. With these definitions, the upper and lower sealants 10 and 11 are defined as first upper and lower sealants 10 and 11.
The detailed assembly structure of the upper and lower frame members 5, 6 will be described later.

The panel body 3 that becomes the sliding door is provided with a guide body (guide roller) 14 at its upper edge that rotates around a vertical axis as a support shaft, and a travel roller 15 at its lower edge that rotates around a horizontal axis as a support shaft. The upper guide body 14 is fitted from below into an upper guide rail 16 shaped like a square that is provided on the lower end surface of the upper frame member 5. The upper guide rail 16 is composed of a first guide piece 16a on the outer side (the extension surface portion 3f side) and a second guide piece 16b on the opposite inner side, so that the guide body 14 fitted from below can be moved and guided in the left-right direction while being sandwiched between the front and rear, and an upper movement mechanism equipped with the guide body 14 and the upper guide rail 16 is arranged in the gap L1 between the upper edge of the panel main body portion 3e and the upper frame member 5.
In contrast, the lower running rollers 15 are placed from above on lower guide rails 17 provided on the upper end surface of the lower frame material 6 and are guided to move left and right, and the lower moving mechanism comprising these running rollers 15 and lower guide rails 17 is arranged in the gap L2 between the lower end edge of the panel main body portion 3e and the lower frame material 6.
The panel body 3 is configured to move left and right to open and close as the guide body 14 is moved and guided by the upper guide rail 16 and the traveling roller 15 is moved and guided by the lower guide rail 17.

As mentioned above, the upper guide rail 16 is configured with the first guide piece 16a on the outer side and the second guide piece 16b on the inner side as front and rear guide surfaces. As the panel body 3 opens and closes, the upper edge of the panel body 3 is guided so that it tilts (biases) outward. This causes the extended surface portion 3f of the panel body 3 to separate from the first upper sealant 10, and the inner surface portion 3b of the panel body 3 to separate from the second upper sealant 13 provided on the upper frame panel material 8. This configuration forms a release guide portion X on the upper guide rail 16 that releases the panel body 3 from tight contact with the first and second upper sealants 10, 13 when it is in the closed position.

In response to this, the inclined panel body 3 must be pulled toward the upright side (inner side) in time with the movement of the panel body 3, which has been moving to open and close the release guide portion X, to the closed position so that the extended surface portion 3f adheres to the first upper sealing material 10 and the inner surface portion 3b of the panel body 3 adheres to the second upper sealing material 13, sealing the inside and outside and providing excellent airtightness and sound insulation, and for this reason the adhesion guide portion Y is formed on the upper guide rail 16.
More specifically, the portion of the upper guide rail 16 corresponding to the close contact guide portion Y is bent so as to bulge inward (protrude inward) relative to the release guide portion X in order to move the guide body 14 and draw the panel body 3 inward relative to the release guide portion X. Therefore, in this embodiment, both the first and second guide pieces 16a, 16b are linear in the left-right direction in the release guide portion X, and at the portion corresponding to the close contact guide portion Y, the first guide plate 18 is attached to the inner side surface of the first guide piece 16a in a stacked state (overlapping state) so as to protrude (protrude inward) with a gap therebetween, and is attached via a screw 18a screwed in from the outside.
On the other hand, the second guide piece 16b has a cutout portion 16c cut out at a position corresponding to the close guide portion Y, and a second guide plate 19 that bulges into the cutout portion 16c (protrudes toward the inside) is attached to the second guide piece 16b from the inside via a screw 19a that is screwed in. In this case, the left-right width of the cutout portion 16c is set wider than the left-right width of the first guide plate 18, so that the first guide plate 18 can be inserted into the cutout portion 16c from the inside and placed against the inner side surface of the first guide piece 16a.

As mentioned above, when the guide body 14 is pulled inward by the first guide plate 18 and moves through the close guide section Y, a cutout portion 16c is formed in the second guide piece portion 16b to allow the guide body 14 to move smoothly through the close guide section Y, but since the cutout portion 16c is covered by the second guide plate 19, it is possible to prevent the guide body 14 from falling off the cutout portion 16c.
Moreover, in this case, the gap between the first guide plate 18 and the second guide plate 19 is set to be approximately the same as the gap between the first and second guide pieces 16a, 16b, so there is no interference with the movement of the guide body 14 between the release guide portion X and the close guide portion Y, or with the movement within the close guide portion Y.
In this way, when the guide body 14 moves from the release guide section X to the close contact guide section Y, the guide body 14 can be easily pulled inward by the upper guide rail 16 by providing the first and second guide plates 18, 19.
In this embodiment, the close-contact guide portion Y is formed by providing first and second guide plates 18 and 19, but the present invention is not limited to this, and it can also be formed, for example, by bending the first and second guide pieces 16a and 16b into corresponding shapes.

12, the upper frame member 5 is assembled by fitting the open-topped, square-shaped lower frame member 5f onto both leg pieces 5e of the open-bottomed, square-shaped upper frame member upper piece 5d, which is attached to the ceiling H, and fastening them from the outside with screws 5g. The groove 5c is formed in the lower end of the outer leg piece 5k of the lower frame member 5f, and the groove 5i, into which the upper edge of the upper frame panel 8 fits, is formed in the upper end of the inner leg piece 5h. The upper guide rail 16 is provided on the straddling piece 5j of the lower frame member 5f.
By forming the upper frame material 5 in this manner, the aforementioned outer side surface 5a of the upper frame material 5 is formed by the outer leg piece 5e of the upper frame material upper piece 5d and the outer leg piece 5k of the upper frame material lower piece 5f, and the inner side surface 5b is formed by the inner leg piece 5e of the upper frame material upper piece 5d and the outer leg piece 5h of the upper frame material lower piece 5f.

13, the lower frame member 6 is attached to the floor F. The upper frame member 6f, which is open on the bottom, is fitted onto both leg pieces 6e of the lower frame member lower piece 6d, which is open on the top, and is assembled by fastening them from the outside with screws 6g. The groove 6c is formed in the upper end of the outer leg piece 6k of the upper frame member 6f, and the lower end of the inner leg piece 6h is formed with a groove 6i into which the lower edge of the lower frame panel material 9 fits. The lower guide rail 17 is also provided on the straddling piece 6j of the lower frame member lower piece 6f.
By forming the lower frame material 6 in this manner, the aforementioned external side surface 6a of the lower frame material 6 is formed by the external leg piece 6e of the lower frame material lower piece 6d and the external leg piece 6k of the lower frame material upper piece 6f, and the internal side surface 6b is formed by the internal leg piece 6e of the lower frame material lower piece 6d and the external leg piece 6h of the lower frame material upper piece 6f.
Furthermore, the lower frame material 6 is provided with an auxiliary fitting 21 fitted into the lower piece 6d of the lower frame material and equipped with an adjuster device 20 for adjusting the up and down position of the lower guide rail 17 at a stage prior to fastening with the screw 6g.

In this embodiment configured as described above, when the sliding door panel 3 moves to open or close, the guide body 14 is guided along the release guide portion X of the upper guide rail 16. As a result, the panel 3 moves in an inclined position with its upper end tilted outward relative to its vertically upright position. As a result, the outward extending surface portion 3f of the inclined panel 3 moves away from the first upper sealant 10 attached to the upper frame member 5, and the inner surface portion 3b moves away from the second upper sealant 13 attached to the upper frame panel member 8, resulting in smooth opening and closing movement without sliding resistance.

As the panel body 3 moves from the opening/closing movement process to the closed position, the portion along which the guide body 14 of the upper guide rail 16 is guided changes from the release guide portion X to the close guide portion Y. As a result, the extended surface portion 3f of the panel body 3 comes into close contact with the first upper seal material 10 provided on the upper frame material 5, and the inner surface portion 3b comes into close contact with the second upper seal material 13 provided on the upper frame panel material 8, thereby achieving a high level of sealing performance and preventing problems such as sound leakage caused by impaired sealing performance.

During the opening and closing movement of the panel body 3, the seals 10, 13 are released, and when the panel body 3 is moved to the closed position, the panel body 3 is tilted forward and backward to allow the seals 10, 13 to seal. This is possible because the upper guide rail 16 is provided with a release guide portion X and a seal guide portion Y. This eliminates the need to provide a seal-release mechanism in a location separate from the upper guide rail 16, reducing the number of parts, simplifying the structure, and preventing it from being visible from the outside, as would be the case if it were provided in a separate location.

Moreover, in this device, the close contact guide portion Y draws and guides the panel body 3, which is moving in an inclined position on the release guide portion X, to the upper frame material 5. This drawing structure is as follows:
Since the release guide portion X is provided by bending the close contact guide portion Y so as to be biased toward the ceiling side frame member, the structure can be simplified.
In this structure, the extending surface portion 3f extending upward from the outer surface portion 3a of the panel body 3 adheres tightly to the upper frame material 5 via the first upper sealing material 10, and the inner surface portion 3b adheres tightly to the upper frame panel material 8 via the second upper sealing material 13.As a result, despite the simple structure, a double adhesion function is achieved both inside and outside, ensuring high sealing performance.
It should be noted that the present invention is not limited to the double inner and outer contact as in this embodiment, and it goes without saying that either the inner or outer contact may be used.

The upper guide rail 16, on which the release guide portion X and the close contact guide portion Y are provided, is configured with a first guide piece portion 16a on the extending surface portion 3f side and a second guide piece portion 16b on the opposite side, and the portion of the first and second guide piece portions 16a, 16b corresponding to the close contact guide portion Y is formed by bending the portion corresponding to the release guide portion X on the opposite side to the extending surface portion 3f. Specifically, at the portion corresponding to the close contact guide portion Y of the first guide piece portion 16a, a first guide plate 18 for drawing and guiding the guide body 14 toward the upper frame panel material 8 is provided in a stacked state with a protruding shape facing inward, so that the configuration for exerting the drawing function can be simplified.
On the other hand, with respect to the second guide piece portion 16b, a cutout portion 16c is formed in the portion corresponding to the close-contact guide portion Y, and a second guide plate 19 is provided in the cutout portion 16c so as to bend in the opposite direction from the extending surface portion 3f, thereby forming a guide surface on the opposite side of the extending surface portion 3f of the close-contact guide portion Y, thereby simplifying the structure here as well.
In this case, the first guide plate 18 is set to be narrower than the width of the cutout portion 16c formed in the second guide piece portion 16b, so that the first guide plate 18 can be placed against the inner surface of the first guide piece portion 16a while passing through the cutout portion 16c, and can be attached from the outside via screws 18a, thereby improving workability.

The present invention can be used as a tight-fitting structure for panel bodies used to separate interior spaces.
