Description

[Technical Field]

[0001] The present invention relates to a structure and a method for closing a fitting groove in a partition that separates an indoor space. [Background technology]

[0002] Today, partitions incorporating panels are used to separate interior spaces into front and rear sections. Some such partitions are configured so that a panel frame is attached to a rail material provided on a structural member such as a ceiling, and the edge of the panel body is fitted into a U-shaped fitting groove formed in the panel frame. When using such a partition to separate an office (workroom) such as a meeting room, improved soundproofing and thermal insulation performance are required, and for this reason, the panel body may be made multi-layered (two panels) rather than single-layered (one panel). When configuring such a multi-layer partition, the panel frame may be formed with a pair of front and rear fitting grooves for attaching two panel bodies. When forming a partition using a panel frame having mating grooves formed at the front and back, the panel frame can be used not only as a multi-layer type in which two panel bodies are incorporated, but also as a single-layer type in which a single panel body is incorporated, in order to accommodate this, there are designs in which the mating groove portion on the side where the panel body is not incorporated is blocked (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a partition (partition panel). The partition 1 of this embodiment is erected to separate an indoor space into a work room (work space) such as a meeting room or office, and a non-work room (non-work space) such as a corridor. In particular, to prevent sounds generated in the work room (for example, voices during a meeting) from leaking into the non-work room, as shown in Fig. 2, a multi-layer (two-layer) panel body 2 (which may be an opaque plate, but may also be made of a transparent or semi-transparent plate such as an acrylic plate or a glass plate) is incorporated to provide excellent soundproofing (sound insulation). By adopting such a multi-layer structure, the partition 1 is configured to have excellent properties not only in soundproofing but also in heat insulation (heat insulation), etc.

[0009] Furthermore, the partition 1 of this embodiment will be described as a planar partition that divides an indoor space into a work room and a non-work room in the front and rear, but it goes without saying that it can also be implemented as an L-shaped or square-shaped partition, in which case the partition 1 will divide the indoor space not only in the front-to-back direction but also, for example, in the left-to-right direction. In light of this, the definition of "front and back" in dividing an indoor space in the front and rear in this invention is defined as "front and back" when the visible surface of the partition panel body 2 is viewed from the front, regardless of the direction in which the indoor space is divided. In this invention, the "front-to-rear" direction is defined as described above, and further, with regard to the orientation of "outside the front-to-rear direction" and "inside the front-to-rear direction," the direction moving away from (away from) the center of the thickness of the front-to-rear thickness of the partition 1 is defined as "outside the front-to-rear direction," and the direction toward the center of the thickness is defined as "inside the front-to-rear direction."

[0010] The present invention is implemented when the multi-layer partition 1 is used as a single-layer partition with only one panel body 2 attached, as described below, but we will first explain the multi-layer partition (multi-layer type) with a pair of panel bodies 2 attached at the front and back. In this structure, upper and lower panel frames 5 and 6 are attached to upper and lower rail members 3 and 4, which are main body members provided on the ceiling surface H and floor surface F, respectively, and a vertical panel frame 7 (upright) is attached to a vertical rail member 7a, which is a main body member provided on the wall surface W.The panel body 2 is inserted and assembled into the rectangular space surrounded by these upper and lower panel frames 5 and 6 and the left and right vertical panel frames 7, thereby forming a flat partition 1 in the left and right directions.

[0011] The upper and lower rail members 3, 4 are U-shaped with an opening on the inside in the vertical direction, with straddling pieces 3a, 4a fixed to the ceiling surface H and floor surface F with screws 3c, 4c, and both leg pieces 3b, 4b standing upright in the vertical direction from the ceiling surface H and floor surface F. Upper and lower panel frames 5, 6 are fitted onto the front and rear leg pieces 3b, 4b, which form the visible surfaces of the upper and lower rail members 3, 4, and the upper and lower positions can be adjusted by adjusting upper and lower adjusters 8, 9 provided between the upper and lower panel frames 5, 6 and the upper and lower rail members 3, 4.

[0012] The upper panel frame 5, the lower panel frame 6, and the left and right vertical panel frames 7 are formed with upper fitting grooves 10, lower fitting grooves 11, and vertical fitting grooves 12 on both the front-to-rear outer sides, into which the upper edge, lower edge, and both left and right end edges of the panel body 2 are respectively fitted, and when forming a multi-layer partition 1, the panel body 2 is fitted and assembled into these fitting grooves 10, 11, and 12. When a partition 1 having such multi-layer panel frames 5, 6, 7 is made into a single-layer specification, the panel body 2 is fitted into the fitting groove portions 10, 11, 12 on one side in the front-to-rear direction, while the panel body 2 is not fitted into the fitting groove portions 10, 11, 12 on the other side.In this case, it is required to seal the fitting groove portions 10, 11, 12 on the other side, and therefore two types of sealing materials 13, 14 are used in this embodiment. In this case, the sealing structure using one sealing material 13 embodies the present invention, while the sealing structure using the other sealing material 14 does not embody the present invention. Therefore, hereinafter, the sealing structure using sealing material 13 that embodies the present invention will be described in detail. In this embodiment, one of the sealing members 13 seals the lower fitting groove 11, and the other sealing member 14 seals the upper fitting groove 10 and the vertical fitting groove 12. However, if necessary, one of the sealing members 13 may be used to seal at least one of the upper fitting groove 10 and the vertical fitting groove 12.

[0013] Next, the structure of the lower panel frame 6 into which the blocking member (one of the blocking members) 13 is incorporated will be described in detail. The lower panel frame 6 is a split type having an U-shaped main frame portion 6a that fits onto the lower rail material 4, and a pair of pressed edge frame portions 6b that are attached to the front-to-rear outer side of the main frame portion 6a. The main frame portion 6a is U-shaped having a spanning piece portion 6aa and front and rear leg piece portions 6ab that hang down from both front and rear end edges of the spanning piece portion 6aa, and the front and rear leg piece portions 6ab form second groove side piece portions 11c on the front-to-rear inner side of the lower fitting groove portion 11, and the front and rear second groove side piece portions 11c are connected front to back by the spanning piece portion 6aa of the main frame portion 6a acting as a connecting piece. Furthermore, bent pieces 6ac are formed from the lower end edges of the front and rear leg pieces 6ab, bending outward in the front-rear direction. These bent pieces 6ac form the groove bottom piece 11a of the lower fitting groove 11. In addition, a main body mounting portion 6ad is formed hanging down from the base end portion of the bent piece portion 6ac, and the main body mounting portion 6ad is attached and fixed to the leg piece portion 4b, which serves as the visible surface portion of the lower rail material 4, via a screw 15, thereby attaching the main body frame portion 6a to the lower rail material 4.

[0014] Furthermore, upper and lower engagement pieces 6ae, 6af are bent outward in the front-to-rear direction on the main body mounting portion 6ad, with the screw 15 sandwiched between them from above and below. An upper engagement protrusion 6ag is formed at the tip edge of the upper engagement piece 6ae so as to protrude upward with a gap remaining between it and the groove bottom piece 11a, and first and second lower engagement protrusions 6ah, 6ai are formed at the tip edge of the lower engagement piece 6af so as to protrude upward both inside and outside in the front-to-rear direction.

[0015] On the other hand, the pushing edge frame portion 6b is configured with an outer piece portion 6ba that constitutes the first groove side piece portion 11b on the outer side in the front-rear direction of the lower fitting groove portion 11. An upper engagement receiving piece portion 6bb is formed at the lower end edge portion of the outer piece portion 6ba by being bent inward in the front-rear direction, and an upper engagement receiving protrusion portion 6bc is formed at the tip edge portion of the upper engagement receiving piece portion 6bb and protrudes downward. Furthermore, a hanging piece 6bd is formed to hang downward from the middle portion of the upper engagement receiving piece 6bb in the fore-and-aft direction, and a lower engagement receiving piece 6be is formed to protrude inward in the fore-and-aft direction from the lower middle portion of the hanging piece 6bd, and a lower engagement receiving protrusion 6bf is formed to protrude downward from the tip edge of the lower engagement receiving piece 6be, and the lower engagement receiving protrusion 6bf is configured to extend parallel to the lower end edge 6bg of the hanging piece 6bd.

[0016] The lower panel frame 6 is then formed by attaching the pressed edge frame portion 6b to the main body frame portion 6a, and in this case, the pressed edge frame portion 6b is in a state in which the upper engaging receiving piece portion 6bb including the upper engaging receiving protrusion 6bc is fitted between the folded piece portion 6ac of the upper main body frame portion 6a and the upper engaging piece portion 6ae including the lower upper engaging protrusion 6ag so as to be freely movable in the front-to-back and up-down directions, and the lower engaging receiving piece portion 6be including the lower engaging receiving protrusion 6bf is fitted between the upper engaging piece portion 6ae including the upper upper engaging protrusion 6ag and the lower engaging piece portion 6af including the lower first and second lower engaging protrusions 6ah, 6ai so as to be freely movable in the front-to-back and up-down directions. Then, by moving the pressed edge frame portion 6b in this fitted state downward so that the lower engagement receiving protrusion 6bf fits between the first lower engagement protrusion 6ah and the second lower engagement protrusion 6ai, the upper engagement receiving protrusion 6bc comes into contact with the upper engagement protrusion 6ag, and the lower engagement receiving protrusion 6bf comes into contact with the second lower engagement protrusion 6ai from the inside in the front-to-back direction, thereby assembling the pressed edge frame portion 6b in a provisionally assembled state with its movement restricted outward in the front-to-back direction.

[0017] In other words, the upper engagement piece portion 6ae including the upper upper engagement protrusion 6ag and the lower engagement piece portion 6af including the lower second lower engagement protrusion 6ai are engagement portions formed on the main frame portion 6a, and the upper engagement receiving piece portion 6bb including the upper engagement receiving protrusion 6bc and the lower engagement receiving piece portion 6be including the lower engagement receiving protrusion 6bf are engagement receiving portions formed on the pushing edge frame portion 6b, and the pushing edge frame portion 6b is configured to be assembled so as to be freely movable in the front-to-back and up-to-down directions while its movement outward in the front-to-back direction and downward in the up-to-down direction is restricted relative to the main frame portion 6a.

[0018] With the pressed edge frame portion 6b temporarily assembled in this manner, the panel body 2 is fitted into one of the lower fitting groove portions 11. In this case, the bead material 16 is fitted between the second groove side piece portion 11c of the lower fitting groove portion 11 and the panel body 2, and the retainer material 17 is force-fitted between the first groove side piece portion 11b and the panel body 2. In this case, the bead material 16 is temporarily fitted into the second groove side piece 11c at a stage before the panel body 2 is fitted into the fitting. The pressed edge frame portion 6b is then temporarily fitted in this state, and in this temporarily fitted state, the panel body 2 is fitted between the bead material 16 and the first groove side piece 11b, and then the retainer material 17 is force-fitted between the panel body 2 and the first groove side piece 11b, thereby attaching the panel body 2 via the pressed edge frame portion 6b at the lower edge. It goes without saying that the procedures for these installation operations can be modified as needed. In this case, the clamping member 17 is made of a hard material that is elastically deformable, such as a hard resin material, and when the clamping member 17 is forcibly fitted between the first groove side piece portion 11b and the panel body 2, the engaging protrusion 17a formed on the clamping member 17 engages with the engaging recess 11ba formed on the inner groove surface of the first groove side piece portion 11b in a non-slip manner, thereby achieving a forcible fitting into the lower fitting groove portion 11 of the panel body 2.

[0019] On the other hand, a blockage member 13 embodying the present invention is fitted into the other lower fitting groove 11 of the panel body 2 that is not fitted in. The blockage member 13 has a U-shape with a spanning piece 13a that closes the open end of the lower fitting groove 11 and first and second leg pieces 13b, 13c that fit into the lower fitting groove 11 while fitting along the first and second groove side pieces 11b, 11c. When the first and second leg pieces 13b, 13c are fitted into the first and second groove side pieces 11b, 11c of the lower fitting groove 11 in a state in which the pressed edge frame portion 6b is temporarily fitted into the main body frame portion 6a, the first and second leg pieces 13b, 13c are fitted in deeply while applying stress in a direction that widens the first and second groove side pieces 11b, 11c. As a result, the locking protrusion 13ca formed on the outer surface of the inner second leg piece 13c locks into the locking recess 11ca formed in the second groove side piece 11c in a non-slip manner, and the locking protrusion 13ba formed on the outer surface of the outer first leg piece 13b locks into the locking recess 11ba formed in the first groove side piece 11b in a non-slip manner so that the locking protrusion 17a of the clamping member 17 engages with it, thereby ensuring that the pressed edge frame portion 6b in the provisionally assembled state is assembled in a non-slip manner.

[0020] The method for closing the lower fitting groove 11 by fitting the sealing material 13 into the lower fitting groove 11 formed by attaching the pressed edge frame portion 6b to the main body frame portion 6a in this manner so as to prevent it from slipping out is as follows: a process of attaching the main body frame portion 6a to the frame side by fixing the main body attachment portion 6ad formed on the main body frame portion 6a to the leg piece portion 4b, which serves as the visible surface portion of the lower rail material 4, via a screw 15; a step of incorporating an engagement receiving portion formed on the pressed edge frame portion 6b into an engagement portion formed on the main body mounting portion 6ad so as to be movable in the front-rear and up-down directions; A process of moving the pushing edge frame portion 6b to a position where movement in the front-rear direction and the up-down direction is restricted to form a provisionally assembled lower fitting groove portion 11; A step of fitting and assembling a sealing material 13 into the provisionally assembled lower fitting groove portion 11; a step of attaching the sealing member 13 to the main frame portion 6a in a state where both the sealing member 13 and the edge frame portion 6b are prevented from coming off by deeply inserting and fitting the sealing member 13 in a non-detachable manner; Each of the steps will be executed in sequence.

[0021] In the embodiment of the present invention configured as described above, the lower panel frame 6 of the multi-layer partition 1 has a pair of front and rear lower fitting grooves 11 into which the lower edge of the panel body 2 is fitted. When the partition is used as a single-layer specification in which one of the lower fitting grooves 11 is fitted with the panel body 2 and the other is filled with a filling material 13, the filling material 13 for filling the other lower fitting groove 11 is provided with a spanning piece 13a that fills the open end of the lower fitting groove 11, a second leg piece 13c that fits into the inner second groove side piece 11c, and a first leg piece 13b that fits into the outer first groove side piece 11b, and the filling material 13 is configured to be fitted into the lower fitting groove 11 in a manner that prevents it from slipping out. Therefore, since the single-layer specification requires that the panel body 2 is not fitted in, it is easy to fill the lower fitting groove 11 on the other side, which is groove-shaped.

[0022] Furthermore, in this case, the blocking material 13 blocking the lower fitting groove portion 11 on the other side has first and second locking protrusions 13ba, 13ca formed on the first and second leg pieces 13b, 13c which are locked in the first and second engaging recesses 11ba, 11ca formed on the first and second groove side pieces 11b, 11c in a non-slip manner, thereby ensuring a secure fitting and assembly of the blocking material 13 in a non-slip manner. It goes without saying that the blocking material 13 for implementing the present invention can also be configured so that at least one of the first and second leg portions 13b, 13c is engaged in a non-slip manner.

[0023] Furthermore, the panel body 2, whose lower edge portion is fitted into one of the lower fitting groove portions 11, is attached in a non-slip manner by a retaining member 17 which is fitted and fitted between the panel body 2 and the first groove side piece portion 11b in a non-slip manner, and the retaining protrusion 17a of the retaining member 17 is configured to engage in a non-slip manner with an engaging recess 11ba formed in the first groove side piece portion 11b, and the engaging protrusion 13ba formed on the blocking material 13 is configured to engage in a non-slip manner, allowing the engaging recess 11ba to be used for both purposes and contributing to simplifying the structure.

[0024] Furthermore, in this device, the lower panel frame 6 is configured as a split type including a main body frame portion 6a having a groove bottom piece 11a of the lower fitting groove 11, a second groove side piece 11c, and a spanning piece portion 6aa which is a connecting piece portion connecting the front and rear second groove side pieces 11c, and front and rear push-edge frame portions 6b which have a first groove side piece 11b and are attached to the main body frame portion 6a. The main body frame portion 6a is attached and fixed to the leg piece portion 4b which is the visible surface portion of the lower rail member 4 with screws 15, and the push-edge frame portion 6b is provisionally assembled to the main body frame portion 6a in a state in which its movement outward in the front-to-back direction and in the up-to-down direction is restricted relative to the main body frame portion 6a. The lower fitting groove 11 formed by this provisional assembly can be easily closed by deeply fitting a closing member 13 into the lower fitting groove 11, thereby simplifying the structure and improving workability.
