Description

The present invention relates to the technical field of panel assembly structures attached to panels such as partition panels used to divide interior spaces.

In general, partition panels are provided to separate the interior spaces of buildings, etc., and some of the panel bodies constituting such partition panels are door bodies that move open and close, and in this case, for example, the upper edge of the panel body is attached to face the inner edge of an upper frame member that constitutes a structural member provided on the ceiling side, with a gap therebetween. In such a structure, when the panel body is a door body that moves open and close, if a component device such as a guide rail or a guide body that runs along the guide rail is provided in the gap between the upper edge of the panel body and the edge of the upper frame member, the component device will be visible from both the front and rear (inside and outside) directions, which will not only spoil the appearance but will also impair the sealing ability, resulting in problems such as poor sound insulation and airtightness.
Therefore, a fitting structure has been proposed in which one side of the gap is covered by an extended surface portion extending outward in the vertical direction from one side of the panel body in the front-to-rear direction, while on the other side, a frame panel material attached to a frame material that constitutes the main body side member is used to cover the other side of the gap (see Patent Document 1).

Patent No. 5358279

However, when the interior side of the frame panel material is a narrow storage room, such as one that houses maintenance tools, the storage room may be shallow (narrow). In such cases, with a structure in which screws are inserted from the frame panel body side, as in the conventional example described above, the screws must be inserted from the narrow interior side, making the work difficult and reducing workability, and these are the issues that the present invention aims to solve.

The present invention was created in consideration of the above-mentioned actual situation and with the aim of solving these problems. The invention of claim 1 is a fitting structure for a panel body, in which a panel body is configured to open and close an opening, the panel body having front and rear panel surface portions, one of the front and rear panel surface portions having an extending surface portion extending outward in the vertical direction from the one panel surface portion and facing one front-to-back side of a main body side member, while the other panel surface portion is configured to face a frame panel material extending inward in the vertical direction from the other side of the main body side member , and the frame panel material is attached to the main body side member via screws inserted from one front-to-back side of the main body side member to the other front-to-back side .
The invention of claim 2 is a panel body fitting structure according to claim 1, characterized in that the screws are inserted through from one side surface of the body side member to the other side surface .
The invention of claim 3 is a panel body fitting structure described in claim 1 or 2, characterized in that a sealing material is attached to the body side member in close contact with the extended surface portion of the panel body in the closed position, and the screws are arranged in a state where the screw heads are covered with the sealing material.
The invention of claim 4 is a fitting structure of the panel body described in claim 3, characterized in that the sealing material is attached by fitting it into a groove formed in the body side member, and the screw head abuts against the bottom of the groove.

By adopting the invention of claim 1, it is possible to avoid impairing the appearance by covering the gap between the main body side member and the panel body with the extended surface portion provided on the panel body and the frame panel material provided on the main body side member, while the screws are attached to the main body side member by inserting the screws from one side in the front-to-rear direction, which is the extended surface portion side of the main body side member, so that attachment can be carried out without any problems even if the depth of the space on the frame panel material side is shallow, and workability is not impaired.
By adopting the invention of claim 2, the screws for attaching the frame panel material penetrate from one side of the main body side member in the front-to-rear direction to the other side, making it easy to securely attach the frame panel material.
By adopting the invention of claim 3, the sealing material attached to the main body side member to ensure airtightness between the extended surface portion and the main body side member is prevented from covering the screw heads used to attach the frame panel material, thereby preventing the appearance from being impaired.
By adopting the invention of claim 4, the screw head is assembled in a state where it abuts against the bottom of the groove formed in the body side member, which is provided for inserting and attaching the sealing material, allowing for easy attachment of the sealing material while also covering the screw head.

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 closed panel body 2 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 closed panel bodies 2 and 3 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 in a square-shaped configuration, and the open-topped, open-bottom upper frame member 6f is fitted onto both leg pieces 6e of the open-topped, square-shaped lower frame member lower piece 6d. The upper and lower frame members are then fastened together with screws 6g from the outside. The groove 6c is formed at the upper end of the outer leg piece 6k of the upper frame member 6f, and the inner leg piece 6h has a groove 6i at the lower end into which the lower edge of the lower frame panel 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, the gaps formed between the upper and lower edges of the panels 2, 3 and the upper and lower frame members 5, 6 for both hinged and sliding doors are covered on the exterior by the extended surfaces 2f, 3f extending from the panels 2, 3, and on the interior by the upper and lower frame panels 8, 9 attached to the upper and lower frame members 5, 6. In this case, the sealing effect of the sealing materials 10, 11, 12, 13, 13a also contributes to excellent sealing performance, providing high airtightness and soundproofing capabilities. Furthermore, taking the upper frame panel member 8 as an example, the upper frame panel member 8 is attached to the upper frame member 5 via screws 8a inserted from the exterior toward the interior, rather than from the interior. As a result, the screws 8a can be inserted from the wider exterior rather than the narrow interior, improving workability. Furthermore, the screws 8a are inserted through the upper frame material 5 from the outside to the inside, making the insertion process easier.

In this case, the screw heads 8b of the screws 8a inserted into the upper frame material 5 are covered by the upper sealing material 10 which seals between the extended surface portions 2f, 3f and the upper frame material 5. In this case, the screw heads 8b fit into the groove 5c provided for fitting and attaching the base 10a of the upper sealing material 10 so that they abut against the bottom of the groove 5c, and are covered by the base 10a of the upper sealing material 10 fitted into the groove 5c, so that they are not visible from the outside. As a result, the screw heads 8b are not visible, resulting in an excellent appearance, and the base 10a of the upper sealing material 10 also serves as a covering member, allowing for effective use.
It goes without saying that the lower panel frame 9 provided on the lower frame member 6 has the same structure as the upper panel frame 8.

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