Description

[Technical Field]

[0001] The present invention relates to the technical field of locking devices for partition panels that are provided to separate indoor spaces. [Background technology]

[0002] Generally, partition panels are installed to divide the interior space of a building, etc. In this case, the panel body that makes up the partition panel is configured as a hinged door, with the rear end of the door pivoted so that it can be opened forward. In a partition panel having such a hinged door-type panel body, a locking device has been provided to lock the panel body in the closed state when the panel body is closed, and an airtight material has been provided between the door edge of the panel body and an opposing member facing the door edge of the panel body (for example, a support pillar or an adjacent panel body on the left and right) to improve airtightness and soundproofing (see, for example, Patent Document 1). In this way, when a locking device and an airtight material are provided on a partition panel having a hinged panel body, the components of the locking device and the airtight material mounting member are both provided on the door-edge side of the panel body and on the panel-facing side of the opposing member. In this case, the conventional system is configured so that a locking plate for the locking device is provided on the door-edge side of the panel body and a locking receiving portion is provided on the panel-facing side of the opposing member, so that the locking plate, when locked, can be releasably engaged with the locking receiving portion. In addition, an airtight material mounting groove, into which the airtight material is attached, is provided on the panel-facing side of the opposing member so as to protrude toward the panel body, while an airtight material abutment portion, against which the airtight material abuts when the panel body is closed, is formed on the door-edge side vertical stile of the panel body, recessed from the rear side of the stile.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-97947 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional system, although both the locking device components and the airtight material mounting components are provided on the door-end side of the panel body and on the opposing side of the panel body of the opposing member, they are composed of separate components, which creates the problem of hindering the reduction of the number of components and installation labor. Furthermore, in the conventional system, the airtight material abutment portion provided on the vertical frame on the door end side of the panel body is formed in a recessed state from the rear side of the vertical frame, which means that the recessed airtight material abutment portion needs to be machined into the vertical frame, which creates the problem of complicated processing steps, and these are the issues that the present invention aims to solve. [Means for solving the problem]

[0005] 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 partition panel in which a panel body for dividing an interior space into front and rear sections is configured as a hinged door type in which the end of the door tail is supported so that it can be opened forward, and the locking plate for the locking device provided on the door front side is configured to be able to be locked by freely engaging and detaching with an engaging receiving portion provided on an opposing member facing the door front side of the panel body in the closed state, and the opposing member is provided with an airtight material mounting groove portion for mounting an airtight material that abuts against the rear side of the panel body in the closed state to provide airtightness, and the groove bottom portion of the airtight material mounting groove is configured as an engaging receiving portion with which the engaging plate in the locked position engages. The invention of claim 2 is a locking device for a partition panel according to claim 1, characterized in that the airtight material has a main body portion incorporated into the airtight material mounting groove portion so that its position in the front-to-rear direction can be freely adjusted. [Effects of the Invention]

[0006] By adopting the invention of claim 1, the mounting groove portion for the airtight material provided on the opposing member functions not only as a mounting member for mounting the airtight material, but also as a locking receiving portion for the locking plate for the locking device provided on the panel body side, allowing the member to be used for multiple purposes, contributing to a reduction in the number of members and installation labor. By adopting the invention of claim 2, even if the front-to-back position of the mounting groove portion for the airtight material relative to the rear side of the panel body is adjusted to match the locking plate on the panel body side, the front-to-back position of the airtight material can also be adjusted accordingly, thereby ensuring sealing with the airtight material.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a first embodiment of the present invention will be described with reference to Figures 1 to 4. In these figures, reference numeral 1 denotes a partition panel for dividing the interior space of a building into front and rear sections. The partition panel 1 is provided to separate a narrow storage room (machine room, inspection room) R, which is partitioned into front and rear sections from the interior space S, for storing (storing) various components such as stored machinery and equipment, devices, and the indoor unit body of an air conditioner. In the following explanation, for convenience, the indoor space S side will be referred to as the "front" or "front side" and the storage room R side will be referred to as the "rear" or "rear side" based on the partition panel 1, but it goes without saying that the present invention is not limited to this explanation.

[0009] On the outer periphery of the partition panel 1, a four-sided frame is provided, which is formed by left and right vertical frame members 4 (wall-side rails) fixed to the wall W, an upper frame member (ceiling-side rail) 5 hanging down from the ceiling surface H, and a lower frame member (floor-side rail) 6 standing upright from the floor surface F. The partition panel 1 is arranged with its outer periphery surrounded by the four-sided frame.

[0010] On the other hand, reference numeral 2 denotes a hinged-door type panel body that constitutes the partition panel 1, and the trailing edge side end of the panel body 2 is hinged via a hinge 8a to a vertical support post 8 attached to the vertical frame member 4 so as to open and close toward the indoor space S side (forward). Note that the trailing edge side end of the panel body 2 is hinged to either the left or right vertical support post 8, and the leading edge side of the panel body 2 in the closed state faces the other vertical support post 8. Hereinafter, the vertical support post located on the trailing edge side (the vertical support post to which the trailing edge side end of the panel body 2 is hinged) will be referred to as the trailing edge side vertical support post 8A, and the vertical support post located on the leading edge side of the panel body 2 will be referred to as the leading edge side vertical support post 8B. These trailing edge side and leading edge side vertical supports 8A, 8B are frame side members fixed to the wall W via the vertical frame member 4.

[0011] The panel body 2 has a front side surface portion 2a as the front side and a rear side surface portion 2b as the rear side as the front and rear surface portions, and a filler material 2c is interposed between these two side surfaces 2a, 2b, and the panel main body portion 2i is configured by being surrounded on all four sides by a trailing edge vertical frame 2e, a leading edge vertical frame 2f, an upper frame 2g, and a lower frame 2h arranged inside the four peripheral edges of both side surfaces 2a, 2b. The rear side surface of the panel body of the present invention is formed by the rear side surface portion 2b. The front side surface portion 2a of the panel body 2 has an extended surface portion 2k formed thereon that extends outward in the vertical direction from the upper and lower end edges of the panel main body portion 2i. When the panel body 2 is in the closed state, the extended surface portion 2k is configured to closely face the front side surfaces 5a, 6a of the upper and lower frame members 5, 6. By being configured in this manner, when the panel body 2 is in the closed state, the gap between the upper and lower end edges of the panel main body portion 2i and the lower upper end edges of the upper and lower frame members 5, 6 is covered from the front side.

[0012] On the other hand, a trailing-door side board mounting frame 10, on which boards 9 are fitted, is provided on the rear side of the trailing-door side vertical support post 8A, extending above and below the trailing-door side vertical support post 8A. The leading-door side end of the trailing-door side board mounting frame 10 protrudes further toward the leading-door side than the leading-door side end of the trailing-door side vertical support post 8A, and is configured to closely face the trailing-door side edge of the panel main body 2i when the panel body 2 is in the closed state. With this configuration, the gap between the trailing-door side edge of the panel main body 2i and the leading-door side edge of the trailing-door side vertical support post 8A is covered from the rear when the panel body 2 is in the closed state.

[0013] Additionally, upper and lower board mounting frames 11, 12, which, like the trailing edge board mounting frame 10, accommodate boards 9, are provided on the rear sides of the upper and lower frame members 5, 6, and extend to the left and right of the upper and lower frame members 5, 6. The lower end of the upper board mounting frame 11 and the upper end of the lower board mounting frame 12 protrude downward and upward from the lower end of the upper frame member 5 and the upper end of the lower frame member 6, respectively, and are configured to closely face the upper and lower ends of the panel main body 2i when the panel body 2 is in the closed state. With this configuration, the gaps between the upper and lower edge portions of the panel main body 2i and the lower-upper edge portions of the upper and lower frame members 5, 6 are covered from the rear when the panel body 2 is in the closed state.

[0014] Furthermore, grooves 10a, 11a, 12a into which airtight materials 13 made of a rubber elastic material are attached are formed at the leading edge, lower edge, and upper edge of the trailing edge, upper, and lower board material mounting frames 10, 11, 12. The airtight materials 13 attached to the grooves 10a, 11a, 12a are in close contact (tight contact, abutment) with the leading edge, upper edge, and lower edge of the rear side surface portion 2b of the panel main body 2i when the panel body 2 is in the closed state, thereby providing airtightness, and are configured to seal the trailing edge, upper side, and lower side of the panel body 2 in the closed state in the front-to-rear direction (inside and outside of the storage chamber R).

[0015] The leading edge vertical frame 2f of the panel body 2 is a hollow rectangle equipped with a front panel 2m, a rear panel 2n, a leading edge side panel 2p, and a trailing edge side panel 2q, and further equipped with a locking piece 2r that protrudes from the leading edge end of the front side 2m toward the leading edge. The front side portion 2a of the panel main body 2i in this leading edge vertical frame 2f portion is provided so as to extend from the front panel 2m of the leading edge vertical frame 2f to the leading edge tip of the locking piece 2r, and the rear side portion 2b of the panel main body 2i is provided so as to extend to the leading edge tip of the rear panel 2n of the leading edge vertical frame 2f.

[0016] On the other hand, the door-end-side vertical support 8B (corresponding to the opposing member of the present invention) that faces the door-end side of the door-end-side vertical stile 2f when the panel body 2 is closed is a hollow rectangular member with a front panel 8b, a rear panel 8c, a door-end-side side panel 8d, and a two-part door-end-side side panel 8e, and is configured so that when the panel body 2 is closed, the door-end-side joint piece 2r of the door-end-side vertical stile 2f faces closely to the front side of the front panel 8b of the door-end-side vertical support 8B, and the door-end-side side panel 8d of the door-end-side vertical support 8B faces closely to the door-end side of the door-end-side side panel 2p of the door-end-side vertical stile 2f. The gap between the front panel 8b of the door-end-side vertical support 8B and the door-end-side joint piece 2r of the door-end-side vertical stile 2f is sealed by an airtight material (cushion material) 14 attached to the joint piece 2r.

[0017] Furthermore, an airtight material mounting member 16, to which an airtight material 15 is attached, is provided on the trailing edge side panel 8d of the leading edge vertical support 8B, extending across the top and bottom of the trailing edge side panel 8d. The airtight material mounting member 16 is formed with an attachment piece 16a attached to the trailing edge side panel 8d of the leading edge vertical support 8B with a screw 17, and an airtight material mounting groove 16b bent from the rear end of the attachment piece 16a and open on the front side, and is attached to the leading edge vertical support 8B in a state in which the airtight material mounting groove 16b protrudes rearward from the rear side panel 2b of the leading edge vertical stile 2f part of the panel main body 2i when the panel body 2 is closed, and the opening side of the airtight material mounting groove 16b faces closely to the leading edge end of the rear side panel 2b. The airtight material 15 attached to the airtight material attachment groove 16b is adapted to adhere tightly to the door-edge side end of the rear side surface 2b of the panel main body 2i when the panel body 2 is in the closed state, thereby providing airtightness, thereby sealing the door-edge side of the panel body 2 in the closed state in the front-to-rear direction (inside and outside of the storage chamber R). Furthermore, the groove bottom of the airtight material attachment groove 16b also serves as a locking receiving portion 23 that constitutes the locking device 20, as will be described later.

[0018] The airtight material 15 attached to the airtight material mounting groove 16b is made of a rubber-like elastic material and includes a main body 15a fitted into the groove of the airtight material mounting groove 16b, a hollow abutment 15b integrally formed with the tip of the main body 15a with its tip protruding forward from the opening of the airtight material mounting groove 16b, and a laminated adjustment part 15c releasably attached to the base end of the main body 15a. The front-to-rear position of the main body 15a can be adjusted by adjusting the number of layers (including "0") of the adjustment part 15c. This allows the door-edge side of the closed panel 2 to be reliably sealed by adjusting the front-to-rear position of the airtight material 15, even if there is a slight difference in the front-to-rear position of the airtight material mounting groove 16b relative to the rear side surface 2b of the panel body.

[0019] On the other hand, 20 is a locking device for locking and unlocking the closed panel body 2 from the interior space S side, and in this embodiment a key lock is used, but the locking device 20 is composed of components such as a lock main body 21, a locking plate 22, and a locking receiving portion 23, which will be described later. The lock main body 21 is attached to the front panel 2m of the door-end vertical stile 2f of the panel body 2, with the tip of the pivot 21a provided in the center of the lock main body 21 penetrating the front panel 2m of the door-end vertical stile 2f and positioned inside the door-end vertical stile 2f. Furthermore, the lock main body 21 is provided with a key hole 21b (shown in Figure 1) into which a key (not shown) is inserted from the indoor space S side, and the pivot 21a can be rotated by turning the key inserted in the key hole 21b, and a locking plate 22 is attached to the tip of the pivot 21a in a state where it rotates integrally with the pivot 21a.

[0020] The locking plate 22 is composed of an attachment piece 22a located inside the door-end vertical frame 2f and attached to the pivot shaft 21a of the lock main body 21, a connecting piece 22b bent at a right angle from the attachment piece 22a toward the rear panel 2n of the door-end vertical frame 2f and protruding rearward through the rear panel 2n and rear side surface portion 2b, and an attachment piece 22c bent at a right angle from the connecting piece 22b. In the unlocked state where the door is not locked with a key, the tip of the locking piece 22c faces upward and is positioned closer to the end of the door than the front side panel 2p of the front vertical frame 2f (see Figure 4(A)). However, by turning the key inserted into the key hole 21b to lock the door, the locking plate 22 rotates integrally with the pivot shaft 21a, and the tip of the locking piece 22c protrudes further towards the door front than the front side panel 2p of the front vertical frame 2f (see Figure 4(B)). The tip of the locking piece 22c in the locked position engages with the locking receiving portion 23 provided on the front vertical support 8B, thereby locking the panel body 2. Here, the locking receiving portion 23 with which the locking plate 22 is releasably engaged is the groove bottom portion of the airtight material mounting groove 16b provided in the leading-edge vertical support 8B. That is, as described above, the airtight material mounting groove 16b protrudes rearward from the rear side surface 2b of the leading-edge vertical stile 2f of the panel main body 2i when the panel body 2 is closed, and the opening side of the airtight material mounting groove 16b is provided in close proximity to the leading-edge end of the rear side surface 2b. This makes it easy to align the tip side of the locking plate 22, which protrudes toward the leading edge in the locked position, with the locking receiving portion 23, which is the groove bottom portion of the airtight material mounting groove 16b. Therefore, there is no need to provide a separate dedicated part for the locking receiving portion 23, and the part can be used for both purposes.

[0021] In the first embodiment configured as described above, the panel 2 constituting the partition panel 1 for dividing the interior space S into front and rear sections is of a hinged door type in which the rear end is pivotally supported so that it can be opened forward, and the panel body 2 is locked by a locking plate 22 of a locking device 20 provided on the door front side of the panel body 2 engaging in a freely engaging manner with a locking receiving portion 23 provided on a door front vertical support 8B (opposing member) facing the door front side of the panel body 2 in the closed state. In this configuration, the door front vertical support 8B is provided with an airtight material mounting groove 16b protruding rearward from the rear side surface 2b of the panel body 2 for mounting an airtight material 15 that abuts against the rear side surface 2b of the panel body 2 in the closed state to provide airtightness, and the groove bottom portion of the airtight material mounting groove 16b is configured as the locking receiving portion 23 with which the locking plate 22 in the locked position engages.

[0022] In this way, in the first embodiment, the door-end vertical support 8B, which is a body-side member provided on the door-end side of the panel body 2, is made to be the opposing member that faces the door-end side of the panel body 2 in the closed state, and the door-end vertical support 8B is fitted with an airtight material mounting groove 16b. The airtight material mounting groove 16b not only functions as a mounting member for mounting the airtight material 15, but also as a locking receiving portion 23 for the locking plate 22 of the locking device 20 provided on the panel body 2 side to be freely engaged and detached, eliminating the need to provide a separate dedicated locking receiving portion and allowing the member to be used for multiple purposes, contributing to a reduction in the number of members and installation labor. Furthermore, the airtight material mounting groove 16b is arranged in a state where it protrudes rearward from the rear side surface 2b of the panel body 2 in the closed state, and the airtight material 15 attached to the airtight material mounting groove 16b abuts against the rear side surface 2b of the panel body 2, so there is no need to process an airtight material abutment portion on the rear side surface 2b of the panel body 2, which simplifies the processing process.

[0023] Furthermore, in this structure, the main body 15a of the airtight material 15 is incorporated into the airtight material mounting groove 16b so that its position in the front-to-rear direction can be adjusted freely. As a result, even if the front-to-rear position of the airtight material mounting groove 16b relative to the rear side surface 2b of the panel body is adjusted to match the locking plate 22 on the panel body 2 side, the front-to-rear position of the airtight material 15 can also be adjusted accordingly, ensuring reliable sealing of the door edge side of the panel body 2 in the closed state.

[0024] Next, a second embodiment of the present invention will be described with reference to Figures 5 and 6. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and the description thereof will be omitted. In Figures 5 and 6, 25 is a partition panel of the second embodiment, and this partition panel 25 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 hinged via hinges 8a to vertical supports 8 attached to vertical frame members 4 so as to open and close toward the interior space S (front), 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, and as shown in Figure 5, the panel body 2 that forms the swing door can be opened and closed in the left-right direction while being open to the front side (the interior space S side) of the storage room R. Furthermore, the partition panel 25, like the partition panel 1 of the first embodiment, is provided to separate the storage room R into front and rear sections relative to the interior space S, and is arranged such that its outer periphery is surrounded by a four-sided frame consisting of left and right vertical frame members 4 and upper and lower frame members 5 and 6. In addition, in the following description of the second embodiment, in order to distinguish between the hinged door panel body 2 and the sliding door panel body 3, the hinged door panel body 2 will be referred to as the hinged door panel body 2 or simply as the panel body 2, and the sliding door panel body 3 will be referred to as the sliding door panel body 3. Note that the sliding door panel body 3 does not correspond to the panel body of the present invention.

[0025] Of the two hinged-door panel bodies 2 on both the left and right ends, one is symmetrical but is similar to the panel body 2 of the first embodiment, and furthermore, like the first embodiment, a locking device 20 for locking the panel body 2 in the closed state is provided on the door-end vertical frame 2f of the panel body 2. As in the first embodiment, the locking device 20 is configured so that by turning the key to place the locking plate 22 in the locking position, the locking piece 22c of the locking plate 22 engages with the locking receiving portion 23, thereby locking the panel body 2; however, as will be described later, the locking receiving portion 23 in the second embodiment is formed by the groove bottom portion of the airtight material mounting groove portion 16b provided on the adjacent sliding-door panel body 3 on the left and right.

[0026] On the other hand, like the hinged door panel body 2, the sliding door panel body 3 has a front side surface portion 3a on the front side and a rear side surface portion 3b on the rear side as the front and back surfaces, and a filler material 3c is interposed between these two side surfaces 3a, 3b, and the panel main body portion 3i is configured to be surrounded on all four sides by left and right vertical frames 3e, 3f, an upper frame (not shown), and a lower frame (not shown).The upper and lower frames of the sliding door panel body 3 are provided with guide rollers and running rollers (neither of which are shown), and the guide rollers and running rollers are guided freely in the left and right direction by upper and lower guide rails (neither of which are shown) provided on the upper frame member 5 and the lower frame member 6, so that the panel can be opened and closed left and right.

[0027] Furthermore, when the vertical frame 3e, 3f on the left and right sides of the sliding door panel body 3 is the vertical frame 3e located on the side of the hinged door panel body 2 when both the hinged door and sliding door panel bodies 2, 3 are closed, a mating member 26 (corresponding to the opposing member of the present invention) is attached to the side of the hinged door of the vertical frame 3e on the side of the hinged door that faces the door leading side of the vertical frame 2f on the door leading side of the hinged door panel body 2. The locking member 26 is a hollow rectangular member having a front panel 26a, a rear panel 26b, a tail side panel 26c, and a leading side panel 26d, and is configured so that when both the hinged door and sliding door panel bodies 2, 3 are closed, the locking piece 2r of the leading vertical frame 2f of the hinged door panel body 2 closely faces the front side of the front panel 26a of the locking member 26, and the trailing side panel 26c of the locking member 26 closely faces the leading side of the leading side panel 2p of the leading vertical frame 2f of the hinged door panel body 2. The gap between the front panel 26a of the locking member 26 and the locking piece 2r of the leading vertical frame 2f is sealed by an airtight material (cushion material) 14 attached to the locking piece 2r.

[0028] Furthermore, an airtight material mounting member 16 similar to that of the first embodiment is attached to the door trailing edge side panel 26c of the joint member 26 via a screw 27. As in the first embodiment, the airtight material mounting groove 16b of the airtight material mounting member 16 protrudes rearward from the rear side surface 2b of the door leading edge vertical stile 2f portion of the hinged door panel body 2 when both the hinged door type and sliding door type panel bodies 2, 3 are closed, and the opening side of the airtight material mounting groove 16b is provided in close proximity to the door leading edge end of the rear side surface 2b of the hinged door panel body 2. The airtight material 15 attached to the airtight material mounting groove 16b is in close contact with the door leading edge end of the rear side surface 2b of the hinged door panel body 2 when both the panel bodies 2, 3 are closed, thereby providing airtightness, thereby providing a seal in the front-to-rear direction between both the panel bodies 2, 3 when closed. Furthermore, as in the first embodiment, the bottom surface of the groove of the airtight material mounting groove portion 16b also serves as the locking receiving portion 23 that receives the locking plate 22 in the locked position of the locking device 20 provided on the hinged door panel body 2, thereby enabling the component to be used for multiple purposes.

[0029] In this way, in the second embodiment, the joint member 26 provided on the sliding door panel body 3 adjacent to the hinged door panel body 2 is made to be an opposing member facing the door tip side of the hinged door panel body 2 in the closed state, and an airtight material mounting groove portion 16b is attached to the joint member 26. Even though the airtight material mounting groove portion 16b is attached to the member on the adjacent panel body side in this way, the airtight material mounting groove portion 16b functions not only as an attachment member for attaching the airtight material 15, but also as a locking receiving portion 23 for detachably engaging the locking plate 22 for the locking device 20 on the hinged door panel body 2 side, thereby achieving the same effect as in the first embodiment and contributing to a reduction in the number of parts and installation labor.

[0030] Of course, the present invention is not limited to the first and second embodiments. In the first embodiment, the door-front vertical support 8B is the opposing member facing the door-front side of the panel body, and in the second embodiment, the mating member 26 provided on the door-tail side vertical frame 3e of the sliding door panel body 3 is the opposing member. However, various body side members facing the door-front side of the hinged door panel body in the closed state, various constituent members of the adjacent panel body, etc. can be appropriately used as the opposing member. [Industrial Applicability]

[0031] The present invention can be used in a locking device for a partition panel that is provided to separate an interior space. [Explanation of symbols]
