Description

[Technical Field]

[0001] The present invention relates to a component for a fixture and a fixture. [Background technology]

[0002] When a crescent and crescent holder are provided on the vertical frame that joins the shoji screen, in order to improve the appearance quality, some designs accommodate the screw member for attaching the crescent holder to the vertical frame in the hollow portion of the vertical frame. That is, the mounting plate of the crescent holder is inserted into the hollow portion of the vertical frame through a side opening, and the screw member is screwed into the vertical frame via the mounting plate through a window hole provided on the visible surface of the hollow portion facing the room, thereby attaching the crescent holder to the vertical frame. The screw member can be concealed by attaching a cap to the window hole in the hollow portion, for example (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-229827 A (Figs. 2 and 6) Summary of the Invention [Problem to be solved by the invention]

[0004] However, when threading a screw through a window hole, it can be difficult to maintain the position of the screw, potentially complicating the work. For example, if the screw insertion hole falls out before the screw is threaded, the screw may fall into the hollow portion of the vertical frame, making it difficult to remove the screw from the hollow portion. Furthermore, if the worker focuses on threading the screw and lets go of the crescent holder, the crescent holder may fall. In particular, when replacing the crescent holder, the above-mentioned work must be performed while the fixture is attached to the frame, so facilitating the work is an important issue.

[0005] In view of the above circumstances, the present invention aims to provide a fitting component and fitting that can be easily attached to the hollow portion of a shaped member without complicating the work. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the building fixture component of the present invention is a building fixture component in which an attachment plate portion is provided so as to protrude sideways from the component body, and the protruding end portion of the attachment plate portion is inserted into a hollow portion from a side opening of the extruded member, and a screw member is screwed into the extruded member through a window hole in the hollow portion and through a screw insertion hole in the attachment plate portion, thereby attaching the building fixture component to the extruded member in a state in which the component body is exposed to the outside, and the protruding end portion of the attachment plate portion is provided with an engagement portion that extends along the length of the extruded member and can be inserted into the hollow portion from the side opening of the extruded member, and a protrusion is provided in a portion of the attachment plate portion below the screw insertion hole so as to reduce the gap in the hollow portion. [Effects of the Invention]

[0007] According to the present invention, when the mounting plate is placed in the hollow portion of the extrusion, the protrusion reduces the gap in the hollow portion. Therefore, even if the screw falls off, it is possible to prevent the screw from falling below the protrusion. Furthermore, even if the mounting plate is placed in the hollow portion of the extrusion and the user releases the fixture component, the engaging portion inserted into the hollow portion abuts against the inner wall of the hollow portion, preventing the fixture component from falling off the extrusion. As a result, it is possible to install fixture components in the hollow portion without complicating the installation process. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Preferred embodiments of fittings and fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "invisible direction" and "visible direction" may be used below. The "invisible direction" is the direction along the depth of the fitting, as indicated by arrow A in the drawings. A surface along the invisible direction may be referred to as a "visible face." The "visible direction" is the direction perpendicular to the invisible direction in the case of an object that extends horizontally, such as a sill. In the case of an object that extends vertically, such as a vertical frame, the "visible direction" is the horizontal direction perpendicular to the invisible direction. A surface along the invisible direction may be referred to as a "visible face."

[0010] 1 to 4 show a fitting equipped with fitting components according to an embodiment of the present invention. The fitting illustrated here is a sliding window in which an outer shoji screen 20 on the outside and an inner shoji screen 30 on the inside are arranged on a frame 10 so that they can slide left and right along the left-right direction. The frame 10 is constructed by assembling left and right vertical frames 11, 12, an upper frame 13, and a lower frame 14 around all four sides. The outer shoji screen 20 is constructed by providing left and right vertical frames 22, 23, an upper frame 24, and a lower frame 25 around the four sides of a rectangular face material 21, while the inner shoji screen 30 is constructed by providing left and right vertical frames 32, 33, an upper frame 34, and a lower frame 35 around the four sides of a rectangular face material 31. These outer shoji screens 20 and inner shoji screens 30 are configured in such a way that when the opening of the frame body 10 is closed, the vertical frame located on the right side of the outer shoji screen 20 (hereinafter referred to as the outer joining frame 23 (shaped member)) and the vertical frame located on the left side of the inner shoji screen 30 (hereinafter referred to as the inner joining frame 33) are arranged side by side in the forward direction when viewed from inside the room.

[0011] The outer and inner stiles 23 and 33 are extruded shapes made of metal such as aluminum alloy or resin, each with a uniform cross-sectional shape along its entire length. In the illustrated example, the outer and inner stiles 23 and 33 are each configured with a stile base 23a, 33a that has a rectangular hollow cross-section. Furthermore, the outer stile 23 has a hollow section 23b with a rectangular cross-section located on the interior side of the stile base 23a. The outer and inner stiles 23 and 33 are also provided with smoke deflectors 23c, 33c that engage with each other when they are installed side by side in the forward direction.

[0012] As is clear from Figure 2, this fitting has a crescent lock 40 and a slide limiting device 50 provided between the inner fitting frame 33 and the outer fitting frame 23. When the crescent lock 40 is locked with the outer fitting frame 20 and the inner fitting frame 30 in the closed position, it prevents the outer fitting frame 20 and the inner fitting frame 30 from sliding relative to each other, thereby maintaining the opening of the frame body 10 in a closed state. The slide limiting device 50 is used to limit the relative sliding distance of the outer fitting frame 20 and the inner fitting frame 30 when the crescent lock 40 is unlocked. The crescent lock 40 is constructed by providing a crescent 41 on the inner fitting frame 33 and a crescent receiver (fitting part) 42 on the outer fitting frame 23. Similarly, the slide limiting device 50 is constructed by providing a pin member 51 on the inner mating frame 33 and an arm member 52 on the outer mating frame 23.

[0013] The crescent 41 has a platter member 44 rotatably disposed relative to a base 43. The platter member 44 is attached to the inner peripheral surface of the inner fitting stile 33 via the base 43, with the rotation axis of the platter member 44 approximately horizontal along the front direction. The platter member 44 is provided with an operating handle 45 for rotating it. The pin member 51 is disposed at the lower portion of the base 43 of the crescent 41 and is supported on the base 43 so that it can move along the front direction. Although not shown in the figure, the tip of the pin member 51, located on the exterior side of the room, has a head with a larger diameter than the shaft at the base end. The pin member 51 can be moved between a state where it protrudes from the base 43 toward the exterior and a state where it is retracted into the base 43 by inserting and operating a key member (not shown) into a key hole 53 provided in the portion of the base 43 facing the interior of the room.

[0014] As shown in Figures 5 to 8, the crescent receiver 42 is configured by providing a hook member 47 at one end of a bracket 46. The bracket 46 is formed by integrally molding a bracket base (component main body) 46a extending in the up-down direction and a flat mounting plate 46b extending laterally from one side edge of the bracket base 46a. The vertical dimension of the mounting plate 46b is smaller than that of the bracket base 46a. The hook member 47 has a hook portion 47b provided at one end of a flat receiving hook base plate 47a, and is fixed to the other side edge of the bracket base 46a via the hook base plate 47a.

[0015] Arm member 52 is a plate-like member whose length is long compared to its width, and is rotatably attached to the lower end of bracket base 46a via a bearing shaft 54 ​​that extends along the projection direction. Arm member 52 is provided with a guide hole 55. Guide hole 55 is a groove-like notch that extends along the longitudinal direction of arm member 52 and is closed at both ends, and is formed with a width that allows the shaft of pin member 51 to be inserted therethrough but does not allow the head of pin member 51 to be inserted therethrough. A wide insertion portion 55a is provided at the end of guide hole 55 closest to bearing shaft 54, allowing the head of pin member 51 to be inserted therethrough. When no external force is applied, arm member 52 hangs down from bracket base 46a due to its own weight, extending vertically downward from bearing shaft 54.

[0016] The mounting plate portion 46b of the bracket 46 is provided with an engagement portion 46c, a protrusion 46d, and a screw insertion hole 46e. The engagement portion 46c protrudes upward from the upper portion of the extended edge of the mounting plate portion 46b. This engagement portion 46c is configured to have a width slightly shorter than the internal dimension of the hollow portion 23b in the outer fitting frame 23 along the projection direction, so that it can be inserted into the hollow portion 23b. A notch 46f is formed at the corner between the engagement portion 46c and the mounting plate portion 46b to reduce the width of the mounting plate portion 46b. More specifically, as shown in FIG. 8(b), the notch 46f is formed so that the maximum dimension d1 from the notch 46f to the extended edge of the mounting plate portion 46b is approximately the same as the width d2 of the mounting plate portion 46b.

[0017] The protrusion 46d is formed by bending a lower portion of the extending edge of the mounting plate 46b. Like the engaging portion 46c, the protrusion 46d is configured to have a width slightly shorter than the internal dimension of the hollow portion 23b along the projection direction. The protrusion 46d's protrusion dimension from the mounting plate 46b is configured to be shorter than the internal dimension of the hollow portion 23b along the projection direction. More specifically, the protrusion 46d is configured so that when the mounting plate 46b is abutted against the front surface of the hollow portion 23b, the gap between the mounting plate 46b and the other front surface is smaller than the outer diameter of the head S1 of a screw member S, which will be described later. When the protrusion 46d is disposed in the hollow portion 23b, the gap between the protrusion 46d and the front surface of the hollow portion 23b is also smaller than the outer diameter of the head S1 of a screw member S, which will be described later.

[0018] The screw insertion holes 46e are through holes with an inner diameter that allows the shaft portion S2 of the screw member S described later to be inserted but not the head portion S1, and two of them are arranged side by side, one above the other, in the part of the mounting plate portion 46b located between the engagement portion 46c and the protrusion portion 46d.

[0019] The crescent receiver 42 having the above-described configuration is attached to the outer joining frame 23 by inserting the mounting plate portion 46b into the hollow portion 23b of the outer joining frame 23, with the hook member 47 and the arm member 52 exposed to the outside of the hollow portion 23b. That is, the outer joining frame 23 has a side opening 23d in the inner peripheral portion of the hollow portion 23b, and a window hole 23e in the portion facing the interior of the room.

[0020] The side opening 23d is located at a height corresponding to the crescent 41 attached to the inner fitting frame 33. Its vertical dimension allows insertion of the mounting plate 46b of the bracket 46 and is smaller than the width from the engagement portion 46c to the protrusion 46d. The width of the side opening 23d is larger than the dimension from the mounting plate 46b to the protrusion 46d. As shown in FIG. 8(b), the engagement portion 46c can be inserted first into this side opening 23d by tilting the crescent receiver 42. Then, with the upper edge of the side opening 23d inserted into the notch 46f, the crescent receiver 42 can be rotated counterclockwise around the upper edge of the side opening 23d to insert the protrusion 46d into the hollow portion 23b.

[0021] The window hole 23e has a vertically elongated hole shape. In this embodiment, the window hole 23e is formed so that when the mounting plate portion 46b of the bracket 46 inserted into the hollow portion 23b through the side opening 23d is positioned at a desired position, the two screw insertion holes 46e provided in the mounting plate portion 46b can be simultaneously exposed to the outside. Therefore, when the mounting plate portion 46b is inserted into the hollow portion 23b through the side opening 23d, the screw member S can be screwed into the outer joining frame 23 through the window hole 23e and the screw insertion holes 46e of the mounting plate portion 46b. This makes it possible to attach the crescent receiver 42 to the outer joining frame 23 with the hook member 47 and the arm member 52 exposed to the outside of the hollow portion 23b.

[0022] In the crescent receiver 42 described above, the vertical dimension of the side opening 23d is smaller than the dimension from the engagement portion 46c to the protrusion 46d on the mounting plate 46b. Therefore, when the mounting plate 46b is inserted into the hollow portion 23b, the engagement portion 46c is inserted above the side opening 23d. Therefore, even if the crescent receiver 42 is released, as shown in FIG. 8(c), the engagement portion 46c abuts against the inner peripheral surface of the hollow portion 23b while the mounting plate 46b abuts against the lower edge of the side opening 23d. Therefore, the crescent receiver 42 can be maintained engaged with the outer frame 23 without falling off. Furthermore, when the protrusion 46d is inserted into the hollow portion 23b, the gap between the hollow portion 23b and the protrusion 46d is smaller than the outer diameter of the head S1 of the screw S. Therefore, even if the screw member S falls out when being screwed through the window hole 23e, the screw member S is received by the protrusion 46d and does not fall to the bottom end of the hollow portion 23b. This makes it possible to remove the screw member S and immediately resume the screwing operation, facilitating the installation of the crescent receiver 42.

[0023] Furthermore, when replacing the crescent lock of an existing sliding window with the crescent lock 40 equipped with the slide limiting device 50 described above, there is a risk that the screw member S will fall into the hollow portion 23b when removing the existing crescent lock. Therefore, when loosening the screw member S of the existing crescent lock, if the engagement portion 46c of the new crescent receiver 42 described above is inserted into the hollow portion 23b through the window hole 23e, it is possible to prevent the screw member S from falling into the hollow portion 23b.

[0024] When the crescent receiver 42 installed as described above is operated with the shoji screens 20 and 30 closed, the plate member 44 engages with the hook portion 47b of the hook member 47, and the crescent lock 40 enters a locked state. This prevents the outer shoji screen 20 and the inner shoji screen 30 from sliding relative to each other, thereby keeping the opening of the frame body 10 closed.

[0025] On the other hand, when the crescent lock 40 is unlocked, a key member (not shown) is inserted into the key hole 53 and operated to protrude the pin member 51, and the head of the pin member 51 penetrates the insertion portion 55a of the guide hole 55 provided in the arm member 52. Therefore, when the outer shoji screen 20 and the inner shoji screen 30 are moved relative to each other from this state, the arm member 52 rotates appropriately and the pin member 51 abuts against the arm member 52 at the end of the guide hole 55. As a result, further relative sliding of the outer shoji screen 20 and the inner shoji screen 30 is restricted, making it possible to ventilate the room while preventing people from entering or exiting, for example.

[0026] In the above-described embodiment, the crescent receiver 42 is attached to the outer joining frame 23 of the outer shoji screen 20, but any other fittings component may be used as long as it is attached by inserting the mounting plate into the hollow portion of the shaped member and threading a screw member through the window hole. Also, if the screw insertion hole 46e formed in the mounting plate 46b is configured as an elongated hole along the extension direction of the mounting plate 46b, it becomes possible to adjust the attachment position of the crescent receiver 42 relative to the shaped member, and it becomes possible to share the crescent receiver 42 with shaped members having different dimensions in the viewing direction, for example.

[0027] Furthermore, in the above-described embodiment, the protrusion 46d is provided integrally with the mounting plate 46b, but the protrusion may be formed by attaching a separately constructed member to the mounting plate 46b. Also, although the engaging portion 46c is provided so as to protrude upward from the mounting plate 46b, the same effect can be achieved by having the engaging portion protrude downward from the mounting plate 46b.

[0028] As described above, the building component of the present invention is a building component in which the mounting plate portion protrudes sideways from the component body, and the protruding end of the mounting plate portion is inserted into a hollow portion through a side opening of the profile, and a screw member is screwed into the profile through a window hole in the hollow portion and through the screw insertion hole of the mounting plate portion, thereby attaching the component body to the profile in a state where it is exposed to the outside.The protruding end of the mounting plate portion is provided with an engagement portion that extends along the length of the profile and can be inserted into the hollow portion from the side opening of the profile, and a protrusion is provided in the portion below the screw insertion hole of the mounting plate portion to reduce the gap in the hollow portion. According to this invention, when the mounting plate is placed in the hollow portion of the extrusion, the gap in the hollow portion is reduced by the protrusion. Therefore, even if the screw falls off, it is possible to prevent the screw from falling below the protrusion. Furthermore, even if the mounting plate is placed in the hollow portion of the extrusion and the fitting part is released, the engaging part inserted into the hollow portion abuts against the inner wall of the hollow portion, preventing the fitting part from falling off the extrusion. As a result, it is possible to install the fitting part in the hollow portion without complicating the installation work.

[0029] Furthermore, the present invention is characterized in that in the above-mentioned fitting component, the engaging portion protrudes from the mounting plate portion toward above the profile. According to this invention, by abutting the engaging portion against a portion of the hollow portion that is above the side opening, it is possible to prevent the fitting component from falling off the profile.

[0030] The present invention is also characterized in that, in the above-mentioned building fixture component, the protrusion is formed by bending the lower edge of the part of the mounting plate that is inserted into the hollow part. According to this invention, since the mounting plate portion and the protruding portion are integral with each other, there is no need to prepare a separate protruding portion.

[0031] The fittings according to the present invention are characterized in that the fitting parts described above are attached to the hollow portions of the frames that constitute the shoji screens. According to this invention, when the mounting plate is placed in the hollow portion of the extrusion, the gap in the hollow portion is reduced by the protrusion. Therefore, even if the screw falls off, it is possible to prevent the screw from falling below the protrusion. Furthermore, even if the mounting plate is placed in the hollow portion of the extrusion and the fitting part is released, the engaging part inserted into the hollow portion abuts against the inner wall of the hollow portion, preventing the fitting part from falling off the extrusion. As a result, it is possible to install the fitting part in the hollow portion without complicating the installation work.

[0032] Furthermore, the present invention is characterized in that in the above-mentioned fittings, the protrusion is configured so that the gap of the hollow portion is smaller than the outer diameter dimension of the head of the screw member. According to this invention, the protrusion makes the gap in the hollow portion smaller than the outer diameter dimension of the head of the screw member, so that even if the screw member falls off, it is possible to reliably prevent it from falling below the protrusion.

[0033] Furthermore, the present invention is characterized in that, in the above-mentioned fittings, the fitting part is a crescent holder provided on the vertical frame that forms the joining point of the outer shoji screen, and the part body is provided with a hook member that engages with the plate member of the crescent provided on the vertical frame that forms the joining point of the inner shoji screen, and supports an arm member that engages with a pin member provided on the vertical frame that forms the joining point of the inner shoji screen. According to this invention, it is possible to attach the crescent holder to the vertical frame that joins the outer screen through a hollow portion without the screw member being exposed to the outside.
