Description

[Technical field]

[0001] The present invention relates to a fixture, such as an outward-tilting window, in which a screen is supported on a frame so that it can rotate around a predetermined axis, and a biasing member is provided between the frame and the screen to bias the screen in an opening direction relative to the frame. [Background technology]

[0002] Some fixtures, such as outward-tilting windows that are installed at a relatively high position, have a biasing member between the frame and the screen. The biasing member biases the screen in the direction of opening it relative to the frame. In this type of fixture, for example, when a wire interposed between the upper frame and the upper stile is loosened by operating an operator device, the biasing member biases the screen against the frame, allowing the screen to be opened (see, for example, Patent Document 1).

[0003] [Patent Document 1] JP 2022-133149 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the above-mentioned fittings, even when the shoji screen is placed in the closed position, it is always biased by the biasing member, and the continuous load can quickly impair the functionality of the hinge members and tension materials installed between the frame and the shoji screen, which is not necessarily desirable in terms of durability.

[0005] In view of the above-mentioned circumstances, an object of the present invention is to provide a fitting capable of improving durability. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the fittings of the present invention are fittings in which a shoji screen is supported on a frame body so that it can rotate around a predetermined axis, and a biasing member is provided between the frame body and the shoji screen which biases the shoji screen in an opening direction relative to the frame body, and the frame body and the shoji screen are provided with stopper members which engage with each other when the shoji screen is placed in the closed position to resist the biasing force of the biasing member. Effect of the Invention

[0007] According to the present invention, the stopper member eliminates the risk of the biasing force of the biasing member being applied to the opening / closing mechanism or the tension material, thereby making it possible to prevent the functions of the opening / closing mechanism and the tension material from being prematurely impaired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A preferred embodiment of the fittings according to the present invention will be described in detail below with reference to the attached drawings. For convenience, the terms "visible direction" and "visible direction" may be used below. The "visible direction" is the direction along the depth of the fittings, as shown by arrow A in the figure. A surface along the visible direction may be called a "visible surface." The "visible direction" is the direction along the top and bottom perpendicular to the visible direction in the case of a bottom frame or the like that extends along the horizontal direction. In the case of a vertical frame or the like that extends along the vertical direction, the horizontal direction perpendicular to the visible direction is called the "visible direction." A surface along the visible direction may be called a "visible surface."

[0010] 1 to 3 show a fitting according to an embodiment of the present invention. The fitting exemplified here is called an outward tilt window, and includes a frame body 10 and a screen 20. The frame body 10 is constructed by assembling a lower frame 11, an upper frame 12, and left and right vertical frames 13 around the four sides. The screen 20 is constructed by attaching a panel 24 such as a double-glazed glass to the inside of a frame body constructed by assembling a lower frame 21, an upper frame 22, and left and right vertical frames 23 around the four sides. The screen 20 is supported by the frame body 10 in a state in which it can rotate around a hinge shaft 25a extending horizontally along the left-right direction by a hinge member 25 provided between the lower frame 21 and the lower frame 11. Although not shown in the figure, a wire is provided on the upper frame 22 of the screen 20 to link it with an operator device. When the wire is paid out via the operator device, the screen 20 can be opened relative to the frame body 10. On the other hand, when the wire is wound up via the operator device, the screen 20 is placed in the closed position relative to the frame body 10. When the screen 20 is opened relative to the frame body 10, the upper frame 22 is rotated in a direction protruding to the outside of the room. When the screen 20 is placed in the closed position, the upper frame 22 faces the projected surface that is the inner periphery of the upper frame 12.

[0011] As is clear from the figure, the lower frame 11, the upper frame 12, and the left and right vertical frames 13 are provided with doorstop walls 11a, 12a, 13a on the interior side of the projected surface, and the doorstop walls 11a, 12a, 13a are provided with watertight materials 14 on the exterior side of the doorstop walls 11a, 12a, 13a. When the shoji screen 20 is placed in the closed position, the watertight materials 14 attached to the frame body 10 abut against the interior side of the projected surfaces of the corresponding frames 21, 22, 23, ensuring watertightness and airtightness in the indoor and outdoor directions. In addition, the left and right vertical frames 23 and the upper frame 22 are provided with outer peripheral walls 23a, 22a extending toward the exterior from the edge that faces the exterior. The outer peripheral wall 23a of the vertical frame 23 is provided with watertight materials 26 toward the exterior side so as to abut against the interior side of the projected surface of the vertical frame 13 when the shoji screen 20 is placed in the closed position. When the screen 20 is placed in the closed position, the outer wall 22a of the upper frame 22 abuts against the tension material 15 attached to the expected surface on the inner periphery of the upper frame 12. Between the vertical frame 13 of the frame body 10 and the vertical frame 23 of the screen 20, a biasing cylinder (biasing member) 30 is provided, and a stopper member 40 is also provided.

[0012] The urging cylinder 30 is a direct-acting type with a built-in damper function, which is not shown in the figure, and is configured so that the piston rod 32 can move forward and backward relative to the cylinder body 31 and is always urged to a protruding state. The urging cylinder 30 is provided with a body bracket 33 at the end on the cylinder body 31 side and a rod bracket 34 at the end on the piston rod 32 side. The body bracket 33 and the rod bracket 34 are rotatable around rotation axes 33a and 34a that are perpendicular to the axis of the urging cylinder 30. In this embodiment, the body bracket 33 is fixed to the projection surface on the outer periphery side of the vertical frame 23, while the rod bracket 34 is fixed to the projection surface on the inner periphery side of the vertical frame 13. When the shoji 20 is placed in the closed position relative to the frame body 10, the upper end of the urging cylinder 30 is inclined so that it is located outside the room more than the lower end. When the screen 20 is placed in a closed position relative to the frame 10 by winding the wire via the operator device, the piston rod 32 of the biasing cylinder 30 is retracted against the biasing force. When the wire is paid out via the operator device, the piston rod 32 is moved forward from the cylinder body 31 by the biasing force, and moves to a position where the screen 20 is opened relative to the frame 10.

[0013] The stopper member 40 engages with the frame body 10 when the screen 20 is placed in the closed position, thereby preventing the screen 20 from moving relative to the frame body 10 against the biasing force of the biasing cylinder 30. In this embodiment, the stopper member 40 is configured by providing an engagement plate 41 on the vertical frame 13 of the frame body 10 and providing a roller 42 on the vertical frame 23 of the screen 20. The engagement plate 41 is integrally provided on the rod bracket (mounting bracket) 34 of the biasing cylinder 30, and is a plate-like member protruding from the lower end of the rod bracket 34 toward the vertical frame 23 of the screen 20. The lower surface 41a of the engagement plate 41 is inclined so that the part located on the indoor side gradually rises upward toward the outdoor side. In the illustrated example, the inclination angle of the part located on the indoor side of the lower surface 41a of the engagement plate 41 is gentle, and the edge located on the outdoor side has a larger upward inclination angle than the part located on the indoor side. The rollers 42 are rotatably supported on the lower end of the roller bracket 43, and are attached to the lower end of the vertical frame 23 via the roller bracket 43 with the rotation axis 42a aligned along the viewing direction. The mounting height of each roller 42 is adjusted so that the upper peripheral surface can engage with the lower surface 41a of the engagement plate 41 when the screen 20 is placed in the closed position.

[0014] In the fittings constructed as described above, when the screen 20 is placed in the closed position, the piston rod 32 is placed in a retracted position relative to the cylinder body 31 of the biasing cylinder 30. However, the roller 42 abuts against the lower surface 41a of the engagement plate 41, thereby resisting the biasing force of the biasing cylinder 30 and preventing the screen 20 from moving upward relative to the frame 10. Therefore, there is no risk of continuous load being applied to the hinge member 25 and the tension materials 14, 15 provided between the frame 10 and the screen 20, and it is possible to prevent the functions of the hinge member 25 and the tension materials 14, 15 from being impaired early.

[0015] In the above embodiment, an outward-tilting window is exemplified, but the present invention can be applied to other windows as long as the shoji screen is supported rotatably relative to the frame body. In addition, the stopper member 40 is exemplified as having the roller 42 and the engagement plate 41, but the stopper member 40 is not necessarily limited to this as long as they engage with each other when the shoji screen 20 is placed in the closed position. In addition, when applying the stopper member 40 having the roller 42 and the engagement plate 41, the engagement plate 41 is provided on the frame body 10 and the roller 42 is provided on the shoji screen 20 in the above embodiment, but it is also possible to provide the roller 42 on the frame body 10 and the engagement plate 41 on the shoji screen 20. Furthermore, the engagement plate 41 is integrally formed with the rod bracket 34, but it is not necessary to provide the engagement plate 41 integrally with the rod bracket 34. Furthermore, the stopper member 40 is provided between the vertical frame 13 and the vertical stile 23, but the position where the stopper member 40 is provided is not necessarily limited to this. Furthermore, in the above-described embodiment, two sets of biasing members and two sets of stopper members are provided, but one set of each is sufficient.

[0016] As described above, the building fixture of the present invention is a building fixture in which a shoji screen is supported on a frame body so that it can rotate around a predetermined axis, and a biasing member is provided between the frame body and the shoji screen which biases the shoji screen in an opening direction relative to the frame body, and is characterized in that the frame body and the shoji screen are provided with stopper members which engage with each other when the shoji screen is placed in the closed position to resist the biasing force of the biasing member. According to this invention, the stopper member eliminates the risk of the biasing force of the biasing member being applied to the opening / closing mechanism or the tension material, making it possible to prevent the functions of the opening / closing mechanism and the tension material from being prematurely impaired.

[0017] The present invention is also characterized in that, in the above-mentioned building fixture, one end of the biasing member is attached to the frame body via a mounting bracket, and the stopper member of the frame body is integrally formed with the mounting bracket. According to this invention, there is no need to secure space for providing a separate stopper member, and there is no concern that the building fixture will become larger.

[0018] Furthermore, the present invention is characterized in that, in the above-mentioned fitting, the stopper member has a roller provided on either the frame body or the shoji screen, and an engagement plate provided on the other of the frame body or the shoji screen, and when the shoji screen is placed in the closed position, the roller engages with the engagement plate to resist the biasing force of the biasing member. According to this invention, the roller can roll on the engagement plate when opening and closing the shoji screen, and there is no risk of significantly affecting the opening and closing operation of the shoji screen.

[0019] Furthermore, the present invention is characterized in that, in the above-mentioned fittings, the frame body has a bottom frame, an top frame and left and right vertical frames, the shoji screen has a bottom stile, an top stile and left and right vertical frames and is supported rotatably around an axis along the left-right direction by a hinge member provided between the bottom stile and the bottom frame, the biasing member is provided between the vertical frame and the vertical stile, and the stopper member comprises a roller provided on the vertical frame in a state of rotating around the axis along the left-right direction, and an engaging plate provided integrally with a mounting bracket for attaching the biasing member to the vertical frame, and the roller engages with the underside of the engaging plate when the shoji screen is placed in the closed position. According to this invention, the roller engages with the underside of the engagement plate, thereby preventing the screen, which is positioned in the closed position, from moving upward due to the biasing force of the biasing member, and preventing the functionality of the opening and closing mechanism and the tension material from being prematurely impaired.

[0020] Furthermore, the present invention is characterized in that, in the above-mentioned fitting, the left and right vertical frames and the left and right vertical stiles are respectively provided with the biasing member and the stopper member. According to this invention, the two biasing members can reliably open the screen, and the two stopper members can reliably receive the biasing force when the screen is in the closed position.
