Description

[Technical field]

[0001] The present invention relates to a screen holder unit that holds a screen to a frame. [Background technology]

[0002] Conventionally, as a shoji holding unit that holds a shoji to a frame, for example, an opening restriction part that is used when constructing an outward-tilting window and is attached across a vertical member bracket to which one end of a damper provided on the outward-tilting window is attached and a shoji bracket to which the other end is attached is known (see, for example, Patent Document 1). This opening restriction part has locking rings formed on both ends of a wire part that forms a string-like member of a predetermined length, and each locking ring is locked to the support shaft of the vertical member bracket and the support shaft of the shoji bracket before the damper is attached. The opening restriction part is attached, for example, by passing each locking ring through the support shaft of the vertical member bracket or the support shaft of the shoji bracket, and then screwing a nut for attaching the damper onto each support shaft. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2022-175139 A Summary of the Invention [Problem to be solved by the invention]

[0004] The opening restriction part is a part that is installed in advance after the outward-tilting window is installed at the construction site, when the damper is installed across the vertical member that forms the frame and the shoji screen, in order to prevent the shoji screen from opening too far, and is removed when the damper is installed. Therefore, if the locking ring parts at both ends of the opening restriction part are both installed with nuts screwed in, there is a problem that when installing and removing the opening restriction part, two nuts must be turned in the narrow space between the vertical member and the shoji screen, making the work complicated. The present invention has been made in consideration of such problems, and its object is to provide a screen retaining unit that is easy to install and remove. [Means for solving the problem]

[0005] The main invention for achieving this objective is a shoji holding unit that holds a shoji screen on a frame body of a building fixture, the shoji holding unit having an axis portion that protrudes between the frame body and the shoji screen, and an enlarged portion that is provided at the tip of the axis portion and has an outer diameter larger than that of the axis portion, a protruding member that is attached to at least one of the frame body and the shoji screen, a wire that has locking portions at both ends that lock to the frame body or the shoji screen, at least one of which is inserted into the protruding member and locked, and a retaining member that is attached to the protruding member through which the locking portions are inserted, the retaining member being annular in shape with an inner diameter smaller than the outer diameter of the enlarged portion, and the inner diameter is larger than the enlarged portion and is elastically deformable. Other features of the present invention will become apparent from the following detailed description of the present invention and the accompanying drawings. Effect of the Invention

[0006] According to the present invention, it is possible to provide a screen retaining unit that is easy to install and remove. [Brief description of the drawings]

[0008] Hereinafter, one embodiment of a screen retaining unit according to the present invention will be described with reference to the drawings. In this embodiment, as an example of a fixture comprising a frame and a shoji screen, a fixture for an outward-tilting window in which the shoji screen is rotatably attached to the frame is taken as an example, and an example of using a shoji screen holding unit when installing and constructing the fixture for an outward-tilting window is described.

[0009] As shown in Figures 1 to 4, the door retaining unit 1 is attached between a door 4 and a frame 5 of a fitting 3 for an outward-tilting window (hereinafter referred to as the fitting) to which a damper 2 is not attached, and is configured so that the opening amount of the door 4 is restricted at a position where it is opened a predetermined amount toward the outside of the room. After the fitting 3 is attached to a building, the door retaining unit 1 is removed by opening the door 4, and the damper 2 is attached.

[0010] The frame 5 of the fitting 3 is framed in a rectangular shape with an upper frame 5a, a lower frame 5b, and left and right vertical frames 5c. The shoji screen 4 has a frame 40 with an upper frame 40a, a lower frame 40b, and left and right vertical frames 40c, and the lower frame 40b is configured to rotate around an axis along the longitudinal direction of the lower frame 5b to open and close.

[0011] The damper 2 is a so-called shock absorber, and is arranged between the vertical frame 5c and the vertical frame 40c on the left and right sides of the frame 40, and is configured to bias the damper 2 in the extension direction when compressed in the longitudinal direction.

[0012] Mounting parts 2a having annular through holes (not shown) are provided on both ends of the damper 2. Each mounting part 2a is inserted into a frame-side support shaft 6a of a frame-side damper support part 6 provided on the vertical frame 5c or a stile-side support shaft 7a of a stile-side damper support part 7 provided on the vertical stile 40c, and is supported rotatably.

[0013] The frame-side damper support part 6 and the stile-side damper support part 7 are provided at opposing positions on the vertical frame 5c or the vertical stile 40c, with the frame-side damper support part 6 provided on the lower side of the vertical frame 5c and the stile-side damper support part 7 provided on the upper side of the vertical stile 40c. The frame-side support shaft 6a and the stile-side support shaft 7a protrude in directions opposing each other and are provided at their tip ends with threaded parts onto which a nut 8 can be screwed.

[0014] The screen retaining unit 1 has a wire 10, a shoulder screw 11, and a washer 12 made of synthetic resin.

[0015] As shown in FIG. 5, the shoulder screw 11 has a thread 11a provided at one end, a shaft 11b connected to the thread 11a and having an outer diameter D1 substantially equal to that of the shaft 11b, and a head 11c provided at the other end and having an outer diameter D2 larger than that of the shaft 11b and connected to the shaft 11b. In this embodiment, the thread 11a is screwed in the vicinity of the frame-side support shaft 6a of the frame-side damper support portion 6 provided on each of the left and right vertical frames 5c. Therefore, the shoulder screw 11 is provided protruding from the vertical frame 5c toward the vertical frame 40c. In this embodiment, the shoulder screw 11 corresponds to the protruding member, and the head 11c corresponds to the enlarged diameter portion.

[0016] 6, the wire 10 has an annular portion 10a as a locking portion in which both ends are bent into a ring shape and crimped. The annular portion 10a is formed to a size that allows the frame side support shaft 6a, the frame side support shaft 7a, and the head 11c of the shoulder screw 11 to be inserted therethrough.

[0017] 7, the washer 12 is annular with a through hole 12a in the center, and when no external force is applied, the inner diameter D3 of the through hole 12a is smaller than the outer diameter D2 of the head 11c of the shoulder screw 11, and is formed so that the shaft portion 11b can be inserted therethrough. When an external force is applied to the washer 12 and the washer 12 is elastically deformed, the through hole 12a can be deformed to a size that allows the head 11c to be inserted therethrough. Here, the washer 12 corresponds to a retaining member attached to the protruding member.

[0018] The shoji retaining unit 1 is attached in advance, for example, between the left and right vertical frames 5c and vertical stiles 40c of the fitting 3 when the fitting 3 is manufactured, without the damper 2 being attached. At this time, the shoulder screw 11 is screwed into each vertical frame 5c with the metal washer 9 sandwiched between the left or right vertical frame 5c and the shaft 11b.

[0019] With the screen 4 open, the screen retaining unit 1 is constructed by inserting one of the annular portions 10a at both ends of the wire 10 into the head 11c of the shoulder screw 11 provided on the lower side of the vertical frame 5c and placing it on the shaft portion 11b. Then, the head 11c of the shoulder screw 11 is inserted into the through hole 12a of the washer 12 and attached to the shaft portion 11b. At this time, the wire 10 is locked by placing the washer 12 between the annular portion 10a and the head 11c of the wire 10.

[0020] The other annular portion 10a of the wire 10 is inserted through the stile side support shaft 7a of the stile side damper support part 7 provided on the upper side of the vertical stile 40c and is secured by screwing a nut 8 onto the stile side support shaft 7a.

[0021] The fitting 3 with the shoji retaining unit 1 attached is transported to the construction site with the shoji 4 in a closed state temporarily fixed to the frame 5. The transported fitting 3 is installed at the construction site, where the temporary fixing is removed and the frame 5 is fixed to the building frame.

[0022] When a door 3 attached to a building is opened, the opening amount of the door 4 is limited by door retaining units 1 attached to the left and right sides. Left and right dampers 2 are attached to the door 3 one by one. That is, one of the left and right door retaining units 1 is removed and the damper 2 is attached, and then the other door retaining unit 1 is removed and the damper 2 is attached.

[0023] The damper 2 is attached, for example, by opening the sliding screen 4, removing the nut 8 screwed onto the stile-side support shaft 7a of the stile-side damper support part 7 provided on the vertical frame 40c, removing the annular part 10a of the wire 10 from the stile-side support shaft 7a, inserting the stile-side support shaft 7a into the through-hole of one of the mounting parts 2a of the damper 2, and screwing the nut 8 onto the stile-side support shaft 7a. This allows the damper 2 to be rotatably attached to the stile-side support shaft 7a.

[0024] Next, the frame side support shaft 6a is inserted into the through hole of the other mounting portion 2a of the damper 2, and the nut 8 is screwed onto the frame side support shaft 6a. As a result, the damper 2 is attached between the vertical frame 5c and the vertical railing 40c.

[0025] Then, the washer 12 inserted into the shoulder screw 11 provided in the vertical frame 5c is pulled in the radially expanding direction while being moved toward the head 11c, thereby elastically deforming the washer 12 and removing it from the shoulder screw 11. Then, the annular portion 10a of the wire 10 is pulled out of the shoulder screw 11, thereby removing the screen retaining unit 1 from the fitting 3.

[0026] According to the shoji retaining unit 1 of this embodiment, the wire 10 having annular portions 10a at both ends is inserted into and engaged with the stepped screw 11 attached to the vertical frame 5c, and the washer 12 attached to the stepped screw 11 is annular with an inner diameter D3 smaller than the head 11c, and the inner diameter D3 is larger than the outer diameter D2 of the head 11c and can be elastically deformed. Therefore, when the washer 12 is inserted into the stepped screw 11, the washer 12 is elastically deformed to insert the head 11c, and the wire 10 can be positioned on the head 11c side of the shaft portion 11b.

[0027] Since the inner diameter D3 of washer 12 in a non-elastically deformed state is smaller than the outer diameter D2 of head 11c, washer 12 arranged on shaft 11b is unlikely to come off shoulder screw 11, making it possible to maintain the locked state of wire 10. Also, when removing washer 12 from shoulder screw 11, it is possible to easily remove wire 10 by simply removing washer 12 and inserting head 11c by elastically deforming washer 12.

[0028] In this way, at least one of the annular portions 10a of the wire 10 can be easily attached and detached by simply elastically deforming the washer 12 without using tools, etc. Therefore, it is possible to provide a screen retaining unit 1 with excellent workability.

[0029] In addition, since one of the two annular portions 10a is engaged with the frame-side damper support portion 7 that supports the mounting portion 2a of the damper 2 in the shoji screen, it is only necessary to attach the shoulder screw 11 to the frame body 5. This makes it possible to reduce the number of parts.

[0030] In addition, because the protruding member to which the annular portion 10a of the wire 10 is locked is the stepped screw 11, when the stepped screw 11 is tightened, a gap is created in the axial direction between the vertical frame 5c and the head 11c. This makes it easier to install because there is no need to adjust the amount of tightening of the screw to leave an axial portion to lock the wire 10, as is the case when the end screw is used as the protruding member.

[0031] In the above embodiment, an example was described in which only one annular portion 10a of the wire 10 is engaged with the shoulder screw 11, but this is not limited to the above. The vertical frame 5c and the vertical frame 40c may each be provided with a shoulder screw 11, and both annular portions 10a at both ends of the wire 10 may be engaged with the shoulder screw 11.

[0032] In addition, in the above embodiment, an example was described in which the wire 10 is engaged with the shoulder screw 11, but the protruding member to which the wire 10 is engaged may be any member that has an enlarged diameter portion whose outer diameter is larger than that of the shaft portion and that can be attached so that the shaft portion protrudes between the frame body and the shoji screen.

[0033] In the above embodiment, the fittings for outward-tilting windows are described as an example, but the present invention is not limited to this. For example, any fittings that have a frame and a paper screen, such as fittings for sliding windows or fittings for vertical sliding windows, may be used. In the above embodiment, the paper screen holder unit is used when installing the fittings, but it may be used not only for installation but also to prevent the fittings from falling during removal work or to prevent them from falling off due to strong winds during normal use.

[0034] The above-mentioned embodiment is for the purpose of facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof. The present embodiment includes at least the following inventions.

[0035] Aspect 1: A shoji holding unit that holds a shoji screen on a frame body of a building fixture, the shoji holding unit having an axle portion that protrudes between the frame body and the shoji screen, and an enlarged portion at the tip of the axle portion and having an outer diameter larger than that of the axle portion, a protruding member attached to at least one of the frame body and the shoji screen, a wire at both ends which is engaged with the frame body or the shoji screen, at least one of which is inserted into the protruding member and engaged, and a retaining member attached to the protruding member through which the engaging portion is inserted, the retaining member being annular with an inner diameter smaller than the outer diameter of the enlarged portion, and the inner diameter being larger than the enlarged portion and capable of elastically deforming.

[0036] According to the shoji holding unit of embodiment 1, a wire having locking portions at both ends is inserted into and locked into a protruding member attached to at least one of the frame body and the shoji, and the holding member attached to the protruding member is annular with an inner diameter smaller than the enlarged diameter portion, and the inner diameter is larger than the enlarged diameter portion and can be elastically deformed. Therefore, when the holding member is inserted into the protruding member, the holding member can be elastically deformed to insert the enlarged diameter portion and be positioned on the enlarged diameter side of the wire in the shaft portion.

[0037] Since the inner diameter of the retaining member in a non-elastically deformed state is smaller than that of the enlarged diameter portion, the retaining member disposed on the shaft portion is unlikely to come off the protruding member, and the wire can be maintained in a locked state. Also, when removing the retaining member from the protruding member, it is possible to remove the retaining member and easily remove the wire by simply elastically deforming the retaining member and inserting it through the enlarged diameter portion.

[0038] In this way, at least one of the engaging portions of the wire can be easily attached and detached simply by elastically deforming the retaining member without using tools, etc. Therefore, it is possible to provide a shoji retaining unit that is easy to attach and detach.

[0039] The screen retaining unit according to aspect 1 is characterized in that the locking portion is annular.

[0040] According to the screen retaining unit of aspect 2, the annular locking portion is easily inserted into the protruding member and difficult to come off, making it easier to install and remove.

[0041] Aspect 3: A screen retaining unit as described in Aspect 1 or Aspect 2, characterized in that the protruding member is a shoulder screw.

[0042] According to the screen retaining unit of the third aspect, the protruding member is a stepped screw, and when the stepped screw is tightened, a gap is created in the axial direction between the frame or screen and the enlarged diameter part. Therefore, unlike when the end screw is used as the protruding member, there is no need to adjust the amount of tightening of the screw to leave the shaft, making installation easier.

[0043] Aspect 4: A screen holding unit as described in any one of Aspects 1 to 3, characterized in that the screen is supported on the frame body so as to be freely rotatable, and one of the two locking portions is locked to one of the support portions that supports an end of a damper that is attached between the screen and the frame body.

[0044] According to the shoji retaining unit of the fourth aspect, one of the two locking parts is locked to one of the support parts that supports the end of the damper, so it is only necessary to attach the protruding member to either the frame or the shoji. This makes it possible to reduce the number of parts.

[0045] Aspect 5: A shoji retaining unit according to any one of Aspects 1 to 4, characterized in that the fixture is for an outward-opening window.

[0046] According to the shoji retaining unit of aspect 5, it is possible to easily regulate the amount of opening of the shoji that opens outward in a fitting for an outward-tilting window. This makes it easier to install the fitting for an outward-tilting window. [Explanation of symbols]
