[0001] The present invention relates to fittings equipped with an operating part such as a lock device. [Background technology]

[0002] Conventionally, a hinged window (fitting) is known that is equipped with a locking device (operating unit) that engages and disengages the locking device main body of the locking device attached to the vertical frame (frame material) of the shoji screen with the vertical frame of the window frame (frame body) (see Patent Document 1). In this hinged window, the locking device main body is provided with an operating handle for operating the locking and unlocking of the shoji screen, an intermediate operating unit that is operated by operating the operating handle, and a base through which the operating handle passes. In addition, the vertical frame has a frame material main body and a batten material (batten) divided into upper and lower parts that engage with the frame material main body, and the intermediate operating unit and base are disposed between the upper and lower batten materials. The upper and lower batten materials and base work together to hold the panel material. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2009-84785 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in a casement window such as that described in Patent Document 1, the batten material is usually designed to have a visible dimension that can accommodate the intermediate operating part, and the base is also configured to match the visible dimension of the batten material.However, when configured in this manner, if the visible dimension of the intermediate operating part is large, for example, the base and batten will also become large in accordance with the visible dimension, making it difficult to reduce the visible dimension of the frame material and improve the design.

[0005] An object of the present invention is to provide a building fixture which can reduce the projection dimension of a frame. [Means for solving the problem]

[0006] The fixture of the present invention is a fixture having a shoji screen that is placed within a frame body and an operating part to which an operating handle is connected, wherein the shoji screen comprises a panel material and a frame material that forms a retaining groove that holds the panel material, and the operating part is attached to the frame material so as to protrude inward from the position of the retaining groove in the viewing direction of the frame material, and at least its protruding end part is covered by a cover material. Effect of the Invention

[0007] According to the present invention, a fitting can be provided that can reduce the projection dimension of the frame material. [Brief description of the drawings]

The X, Y, and Z axis directions are perpendicular to each other.

[0010] The frame 2 is composed of an upper frame 21, a lower frame 22, and left and right vertical frames 23, and the shoji screen 3 is composed of a panel material 35 such as a glass panel arranged inside a frame body composed of an upper frame 31, a lower frame 32, and left and right vertical frames 33 (frame materials) formed of aluminum extrusions. The locking device 5 is composed of a cremone lock in this embodiment, and includes a locking device main body 51 attached to one of the left and right vertical frames 33 as shown in Figure 2, and a lock receiving part (not shown) attached to one of the left and right vertical frames 23 arranged opposite the vertical frame 33, and the locking device main body 51 includes an operating part 52 and an operating handle 53 for operating the operating part 52.

[0011] As shown in FIGS. 2 to 5, the vertical frame 33 includes a frame body 36 formed from an aluminum extrusion material, and a pressing edge 41 that engages with the frame body 36. The frame body 36 has a frame-finishing surface portion 37 along the X-axis direction that receives the exterior surface 35A of the panel material 35, and a frame-in-place surface portion 38 along the Z-axis direction that is continuous with the frame-finishing surface portion 37, and the frame-in-place surface portion 38 on the interior side is configured with an engaged portion 381 with which a pressing edge, which will be described later, engages. Also, as shown in Fig. 4, the frame-in-place surface portion 38 on the interior side has a hollow rectangular frame portion 382 along the Y-axis direction, and a portion of the rectangular frame portion 382 is cut out so that the locking device body 51 and a liner 61, which will be described later, can be provided. The flange 41 has a metal flange portion 42 made of an aluminum extrusion, and a resin flange portion 43 made of a resin extrusion that fits into and combines with the metal flange portion 42. The metal flange portion 42 has an engagement piece portion 421 that engages with the engaged portion 381, and a fitting piece portion 422 that is continuous with the engagement piece portion 421 and into which the resin flange portion 43 fits, and the fitting piece portion 422 is disposed opposite the indoor surface 35B of the panel material 35 when the engagement piece portion 421 and the engaged portion 381 are engaged. The resin pressing edge portion 43 has a hollow rectangular hollow frame portion 430 formed by a pair of pressing edge sighting surfaces 431, 432 and a pair of pressing edge prospecting surfaces 433, 434 extending in the Y-axis direction in a hollow rectangular shape, an engagement portion 435 extending from the continuous portion of the pressing edge sighting surface portion 431 and the pressing edge prospecting surface portion 434 to the outside (vertical frame 23 side) in the X-axis direction, and a fitting portion 436 extending from the continuous portion of the pressing edge sighting surface portion 432 and the pair of pressing edge prospecting surfaces 433, 434 to the room side (panel material 35 side) in the Z-axis direction, and the engagement portion 435 engages with the engaged portion 381 of the frame body 36, and the fitting portion 436 fits into the fitting piece portion 422. In addition, a partition piece portion 438 that partitions the hollow portion is formed inside the hollow frame portion 430. In this flange 41, a notch 439 in which the operating section 52 is arranged is formed in the flange sighting surface portion 431, the flange projection surface portions 433, 434 and a part of the partition piece portion 438, and the flange sighting surface portion 432 extends continuously in the Y-axis direction from the upper end to the lower end of the frame. This vertical frame 33 forms an approximately U-shaped retaining groove 49 that holds the panel material 35 by the frame facing surface portion 37 of the frame main body 36, the frame recessed surface portion 38, and the fitting piece portion 422 and fitting portion 436 of the push edge 41.

[0012] The locking device main body 51 is equipped with an operating part 52 that moves a slide bar 55 arranged along the frame projection surface portion 38 in the Y-axis direction, and an operating handle 53 whose shaft portion 531 is connected to the operating part 52 and is positioned on the indoor side relative to the position of the push edge 41. The operating part 52 incorporates a transmission mechanism (not shown) composed of gears, cams, etc., which transmits the rotation operation of the operating handle 53 about the shaft part 531 as the up and down movement of the slide bar 55, and is inserted into an arrangement hole 380 (see FIG. 4) formed on the interior side of the frame projection part 38 and is disposed so as to protrude in the X-axis direction from the notch 439 (see FIG. 5). This operating part 52 protrudes inward in the X-axis direction from the position of the holding groove 49. The operating handle 53 includes a handle 532 having a shaft portion 531, and a base 533 on which the handle 532 is seated. In addition, the slide bar 55 is connected to a linkage bar (not shown), and by moving up and down in the Y-axis direction it engages and disengages with the lock receiving portion provided on the vertical frame 23, thereby locking and unlocking the shoji screen 3 by the locking device 5.

[0013] Here, a liner 61 is disposed as a reinforcing member between side surface portion 52A on the indoor side along the X-axis direction of operating portion 52 and a visible portion 73 of cover material 71 described later (see Figs. 2 and 4). Liner 61 is made of aluminum die-cast (ADC12 JIS standard), and has plate-shaped main body portion 62 along the X-axis direction arranged along side surface portion 52A of operating portion 52, upper fixing portion 63 and lower fixing portion 64 extending vertically from main body portion 62, and upper piece portion 65 and lower piece portion 66 bent in the Z-axis direction from the upper and lower edges of main body portion 62. The upper fixing part 63 and the lower fixing part 64 are fixed to the interior part of the frame recessed surface part 38 of the vertical frame 33 by screws 69, the upper piece part 65 and the lower piece part 66 are arranged in a position to sandwich the operating part 52 from above and below, the main part 62 is arranged in contact with the side part 52A of the operating part 52, and the main part 62 is formed with a hole 621 through which the screw 54 for fixing the shaft part 531 and the base 533 of the operating handle 53 is inserted (see FIG. 5). This liner 61 reinforces the periphery of the operating handle 53 at the cutout part 439 of the vertical frame 33 so as to resist the load applied when the locking device main body 51 is operated.

[0014] A cover material 71 is disposed in the cutout portion 439 of the vertical frame 33 (see FIGS. 2 and 5). The cover material 71 is made of zinc die-cast (ZDC2 JIS standard) and has a recessed portion 72 and a visible portion 73 that cover the operating portion 52. The projection portion 72 has a projection main body portion 721, an upper portion 722 and a lower portion 723 continuous with the upper and lower edges of the projection main body portion, and a facing portion 724 disposed at a position on the inner periphery side of the retaining groove 49 in the X-axis direction and facing the indoor surface 35B of the panel material 35, and covers the protruding end portion 521 of the operating portion 52 protruding in the X-axis direction from the pressing edge 41. As shown in FIG. 2, the outer surface of the projection main body portion 721 is inclined with respect to the Z-axis direction so that the edge on the handle 532 side is disposed at a position on the outer periphery side of the edge on the panel material 35 side. The facing portion 724 is inclined with respect to the X-axis direction (in-plane direction of the panel material 35) so that the position on the inner periphery side is separated from the panel material 35 in the Z-axis direction from the position on the outer periphery side, and is disposed at a position on the indoor side of the fitting portion 436. The sighting portion 73 is formed in a generally rectangular plate shape that is continuous with the room side portion (the portion on the operating handle 53 side) of the projection portion 72 and extends outward in the X-axis direction. The sighting portion 73 is also formed with holes 731 through which screws 54 for fixing the shaft portion 531 and the base 533 are inserted. The sighting portion 73 is disposed between the main body portion 62 of the liner 61 and the base 533 of the operating handle 53. Therefore, the sighting portion 73 is also disposed between the actuation portion 52 and the operating handle 53. The cover material 71 is disposed in the cutout portion 439 to cover the entire cutout portion 439 from the outside.

[0015] The locking device main body 51 and its periphery in the above-described casement window 1 are assembled as follows. First, as shown in FIG. 4, the upper fixing portion 63 and the lower fixing portion 64 of the liner 61 are screwed to the indoor portion of the frame recessed surface portion 38 of the vertical frame 33 by the screw 69, and the operating portion 52 is screwed to the indoor portion of the frame recessed surface portion 38 by the screw 56 while passing through the arrangement hole 380. Then, with the panel material 35 arranged inside the frame, the engagement piece portion 421 and the engagement portion 435 of the pressing edge 41 are engaged with the engaged portion 381 of the frame recessed surface portion 38, and the pressing edge 41 is attached to the frame material main body 36. At this time, the vertical frame 33 forms the above-mentioned holding groove 49, and the panel material 35 is held in the holding groove 49. Also, a part of the operating portion 52 is arranged to protrude inward in the X-axis direction from the pressing edge 41, and the operating portion 52 and the main body portion 62 of the liner 61 are arranged to overlap in the Z-axis direction as shown in FIG. Next, the cover material 71 shown in Fig. 5 is arranged to cover the notch 439 of the pressing edge 41 as shown in Fig. 3. The projection 72 is arranged to cover the protruding end 521, which is a part of the operating part 52 that protrudes inward in the X-axis direction from the pressing edge 41, from the inner periphery side, and the sight part 73 is arranged to cover the side part 52A of the operating part 52 and the main body part 62 of the liner 61 from the room side. Next, the shaft part 531 of the handle 532 and the screw 54 that fixes the base 533 are inserted into the holes 621, 731, the shaft part 531 is fitted into the operating part 52 so as to be capable of transmitting rotational operation, and the screw 54 is screwed into the operating part 52. A caulking material 91 (sealing material) and a backup material 92 are provided between the frame mounting surface portion 37 and the ridge 41 and the panel material 35. First, the backup material 92 is installed, and then the caulking material 91 is discharged from the caulking nozzle 95 shown in FIG. 6. Here, the projection portion 72 of the cover material 71 is disposed on the inside in the Y-axis direction from the ridge 41, but since the facing portion 724 is inclined as described above, when the caulking material 91 is discharged between the ridge 41 and the panel material 35 from the caulking nozzle 95 as shown in FIG. 6, the cover material 71 is prevented from interfering with the caulking nozzle 95. The outer surface of the projection main body portion 721 is inclined as described above, which also prevents the cover material 71 from interfering with the caulking nozzle 95. In this manner, the lock device main body 51 and its periphery are assembled. The protruding end 521 of the operating portion 52 is disposed to protrude inward in the X-axis direction from the notch 439 of the vertically continuous pressing edge 41, and this notch 439 is covered with the cover material 71 together with the protruding end 521. This configuration allows the visible dimension of the pressing edge 41 to be reduced without being restricted by the visible dimension of the operating portion 52, and allows the design to be improved without exposing the operating portion 52 to the outside. Furthermore, the provision of the liner 61 allows reinforcement so as to be able to resist the force applied to the peripheral configuration of the operating handle 53 when the operating handle 53 is operated.

[0016] [Variations] In the above embodiment, the notch 439 of the edge 41 is formed from a part of the edge projection surface 433 to the edge sighting surface 431, but this is not limited thereto, and as long as the protruding end 521 of the operating part 52 can be arranged in a state where it protrudes from the edge 41, the notch may be formed only in a part of the edge projection surface 433. In this case, the edge sighting surface 431 is formed with holes for passing the shaft 531 and the screw 54, and the cover material 71 is arranged to cover the notch together with the operating part 52 on only a part of the edge projection surface 433. In the embodiment, the liner 61 is made of aluminum die-casting, but it is not limited to this and may be made of other materials as long as it can sufficiently reinforce the peripheral configuration of the actuation portion 52 and the operating handle 53. In addition, the cover material 71 is made of zinc die-casting, but it is not limited to this and may be made of other materials as long as it is configured to cover the cutout portion 439 and the actuation portion 52. In the above embodiment, a liner 61 is provided as a reinforcing member in which the main body 62 is disposed between the operating part 52 and the cover material 71 in the Z-axis direction, but this is not limited to the above, and if the surrounding structure of the operating handle 53 is sufficiently strong even without providing the liner 61, the structure of the liner 61 may be omitted. In the above embodiment, the press edge 41 is formed by combining the resin press edge portion 43 and the metal press edge portion 42, but the press edge 41 is not limited to this and may be made of metal or resin. In the above embodiment, the facing portion 724 of the cover material 71 and the outer surface of the projecting main body portion 721 are inclined as described above, but this is not limited thereto and they may be arranged along the X-axis direction or Z-axis direction without being inclined.

[0017] [Summary of the invention] (1) The fixture of the present invention is a fixture having a screen that is placed within a frame body and an operating part to which an operating handle is connected, the screen comprising a panel material and a frame material that forms a retaining groove that holds the panel material, and the operating part is attached to the frame material so as to protrude inward from the position of the retaining groove in the viewing direction of the frame material, and at least its protruding end part is covered by a cover material. According to the building fixture of the present invention, the operating part to which the operating handle is connected is positioned protruding inward from the position of the retaining groove of the frame material, so that the visible dimensions of the frame material can be reduced except for the part where the operating part and the operating handle are provided, and since at least the protruding end part of the operating part is covered by the cover material, the visible dimensions can be reduced and the external design of the slimmed-down frame material can be improved. (2) In the building fixture of the present invention, the frame has a frame body and a push edge that engages with the frame body and continues in the vertical direction to form part of the retaining groove, and the operating part may be positioned protruding from the push edge in the viewing direction of the frame. With this configuration, even in the case of a frame to which an operating part is attached, the projection dimension of the frame can be reduced without having to divide the edge into upper and lower parts, and the effort required to engage the edge with the frame body can be reduced. (3) In the building fixture of the present invention, the edge has a edge projection surface portion and an edge visible surface portion, and a cutout portion is formed from a part of the edge projection surface portion to the edge visible surface portion, and the cutout portion may be covered with the covering material. With this configuration, the aforementioned cutout portion can be formed while keeping the pressing edge continuous from top to bottom, and the operating part can be positioned to protrude from this cutout portion.Furthermore, the cutout portion together with the operating part can be covered with a cover material, thereby improving the design. (4) In the building fixture of the present invention, the flange has a metal flange portion that holds the panel material and a resin flange portion that is combined with the metal flange portion, and the cutout portion may be formed in the resin flange portion. With this configuration, the panel material is held by the metal edge portion, thereby improving the retention of the panel material in the holding groove described above, while the aforementioned cutout portion is formed in the resin edge portion, making it easy to process the cutout portion. (5) In the building fixture of the present invention, the cover material has a recessed portion covering the protruding end of the operating part and a visible portion continuous with the recessed portion, and the visible portion may be positioned between the operating part and the operating handle. With this configuration, not only is the protruding end of the operating part covered by the recessed portion of the cover material, but the visible portion is also positioned between the operating part and the operating handle, so that the side portion of the operating part can also be covered by the visible portion. (6) In the fitting of the present invention, a reinforcing member fixed to the frame material may be disposed between the side portion of the operating portion and the visible portion. With this configuration, the reinforcing member fixed to the frame material is positioned between the side portion of the operating part and the visible portion, thereby improving the strength of the operating part and the area around the operating handle, and enabling the operating handle to be supported suitably even when being operated. (7) In the building fixture of the present invention, the cover material has a facing portion that is positioned at a position more inward than the retaining groove in the viewing direction of the frame material and faces the panel material, and the facing portion may be inclined with respect to the in-plane direction of the panel material so that its inner position is farther away from the panel material than its outer position. With this configuration, the facing portion of the cover material is inclined as described above, so that the space between the panel material and the cover material expands from the outer periphery to the inner periphery. This reduces the risk of the caulking nozzle interfering with the cover material, for example, when applying caulking material between the panel material and the retaining groove.
