Description

[Technical Field]

[0001] The present disclosure relates to a crescent receiving member. [Background technology]

[0002] A technique has been known in the past in which a crescent lock is attached to the joint (external joint frame and internal joint frame) of a sliding window consisting of an inner and outer shoji screen (see, for example, Patent Document 1). The crescent lock includes a crescent and a crescent receiving fitting (crescent receiving member) that can engage with the crescent.

[0003] The crescent holder described in Patent Document 1 is constructed in two parts, and one part is guided by a drawn groove formed in one part and a drawn groove formed in the other part, allowing the other part to move laterally relative to the other part, and the lateral position can be adjusted and fixed with screws. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-173490 Summary of the Invention [Problem to be solved by the invention]

[0005] When the one and other grooves of one and the other member of a two-piece crescent bracket are formed by drawing, the edges of the one and other grooves have gently sloping surfaces, which can cause the guided portion to come off. Also, because the one and other grooves are formed by drawing, the area around the screw hole can be deformed, which can reduce the accuracy of the screw fixing position.

[0006] It is difficult to form one and the other grooves by drawing so that the guided portion can be positioned accurately and without coming off in one and the other members of a two-piece crescent holder. Therefore, a demand exists for a two-piece crescent holder member that can be easily processed and that can accurately position the guided portion so that it is difficult to come off when the two members are combined.

[0007] The present disclosure aims to provide a crescent holder that is easy to process and that can be accurately positioned so that the guided portion is less likely to come off when the two parts of the crescent holder are combined and are configured in two separate pieces. [Means for solving the problem]

[0008] The present disclosure relates to a crescent support member that is provided at the joint of an inner shoji screen and an outer shoji screen and is capable of engaging with a crescent, comprising: a base that is fixed to the vertical frame of the outer shoji screen at the joint; and a support portion that is fixed to the base with its position relative to the base adjusted and engages with the crescent to receive the crescent, and a pair of guide portions are formed at the upper and lower ends of either the base or the support portion to regulate the vertical position of the other of the base or the support portion.

[0010] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. A sliding window 1 constituting a fixture according to one embodiment will be described. In this specification, the "visible direction" refers to the surface direction of the face panels 35, 45 of the sliding window 1 placed in an opening formed in the wall of a building, and the "visible direction" refers to the thickness direction (i.e., the depth direction) of the face panels 35, 45. The "visible direction" also refers to the indoor / outdoor direction. The "visible surface" refers to the surface of the sliding window 1 facing the outside and the inside, respectively, and the "visible surface" refers to the surface of the sliding window 1 extending in the indoor / outdoor direction. In the drawings, the outdoor side of the sliding window 1 is designated as the outdoor side X1, and the indoor side of the sliding window 1 is designated as the indoor side X2.

[0011] As shown in Figure 1, a sliding window 1 is made up of a frame 2 attached to an opening in a building frame (not shown), and two shoji screens, an outer shoji screen 3 placed on the outside X1 (see Figure 2) and an inner shoji screen 4 placed on the inside X2 (see Figure 2), fitted inside the frame 2. The outer shoji screen 3 and inner shoji screen 4 can slide left and right (horizontally) within the frame 2 in the facing direction.

[0012] The frame body 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24 in a rectangular shape. The upper frame 21 is disposed above the frame body 2. The lower frame 22 is disposed below the frame body 2.

[0013] As shown in Figure 1, the outer shoji screen 3 is constructed by fitting a panel 35 made of three pieces of glass inside a rectangular frame body 30 consisting of an upper frame 31, a lower frame 32, a vertical frame 33 located at the front of the door, and an outer joint frame 34, which is a vertical frame located at the rear of the door.

[0021] The inner joint frame cover member 442 is formed in a generally L-shaped cross section and is arranged to cover the visible surface on the opposite side of the face material 45 in the visible direction of the inner joint frame body 441 and the visible surface on the indoor side X2. A crescent 7 is attached to the visible surface 442a of the inner joint frame cover member 442 on the opposite side of the face material 45 in the left-right direction.

[0022] The outer joint frame 34 of the outer shoji screen 3 is positioned on the outdoor side X1 of the joint section 5. The outer joint frame 34 has an outer joint frame body 341 which is a hollow structure with a hollow section 341a. On the surface material 35 side of the outer joint frame body 341, a surface material placement recess 341b is formed which opens out towards the side of the surface material 35 side.

[0023] An indoor side facing direction extending wall portion 343 extending in the facing direction is formed on the indoor side X2 portion of the outer joint frame body 341. A crescent receiving member 8 is fixed to the indoor side facing direction extending wall portion 343.

[0024] The crescent lock 6 will now be described. As shown in Figures 2 and 3, the crescent lock 6 includes a crescent 7 and a crescent receiving member 8 that can be engaged with the crescent 7.

[0025] 2 and 3, the crescent 7 is provided on the inner joint frame 44 of the inner shoji screen 4 at the joint portion 5. The crescent 7 is fixed to the visible surface 442a of the inner joint frame cover member 442.

[0026] The crescent 7 includes a base 71 fixed to the visible surface 442a of the inner joint stile cover member 442, a rotating part 72 having a hook member 73, and a lever member 74 that rotates the rotating part 72. The crescent 7 can be operated by rotating the lever member 74 to rotate the rotating part 72, and to switch between a locked state in which the hook member 73 engages with a crescent engaging portion 824 (described below) of the crescent receiving member 8 to lock it, and an unlocked state in which the hook member 73 disengages from the crescent engaging portion 824 of the crescent receiving member 8.

[0027] The crescent support member 8 is configured with a width in the vertical direction and extends in the visible direction (horizontal direction) from the outer joint frame 34 on the door base side of the outer shoji 3 to the vertical frame 33 on the door tip side.

[0028] In the description of this embodiment, the direction in which the crescent support member 8 extends is referred to as the horizontal direction D. In this embodiment, the horizontal direction D of the crescent support member 8 coincides with the left-right direction (horizontal direction) of the outer shoji screen 3 and the inner shoji screen 4. The base end of the crescent support member 8 in the horizontal direction D that is fixed to the outer joint frame 34 is referred to as one side D1, and the tip end of the crescent support member 8 in the horizontal direction D is referred to as the other side D2.

[0029] The base end of the crescent support member 8 on one side D1 in the horizontal direction D is fixed to the wall portion 343 extending in the indoor direction of the outer joining frame 34 of the outer shoji screen 3.

[0035] The first inclined step portion 812a is configured as a step between the stile-side fixing plate 811 and the first left-right extending portion 812b, and is inclined from the indoor side X2 toward the outdoor side X1 as it moves from one side D1 to the other side D2 in the horizontal direction D. The first left-right extending portion 812b is formed in a flat plate shape extending from the end of the other side D2 in the horizontal direction D of the first inclined step portion 812a to the other side D2.

[0036] The second inclined stepped portion 812c is configured as a step between the first left-right extending portion 812b and the second left-right extending portion 812d, and is inclined from the outside side X1 to the inside side X2 as it moves from one side D1 to the other side D2 in the horizontal direction D. The second left-right extending portion 812d is formed in a flat plate shape extending from an end of the other side D2 in the horizontal direction D of the second left-right extending portion 812d to the other side D2.

[0037] The third step inclined portion 812e is configured as a step between the second left-right extending portion 812d and the receiving portion side connecting plate 813, and inclines from the outside side X1 to the inside side X2 as it moves from one side D1 to the other side D2 in the horizontal direction D.

[0038] The receiving portion side connecting plate 813 is connected to an end portion of the other side D2 in the horizontal direction D of the stepped extending plate 812. The receiving portion side connecting plate 813 extends from an end portion of the other side D2 in the horizontal direction D of the third stepped inclined portion 812e to the other side D2. The receiving portion side connecting plate 813 is formed in a flat plate shape extending in the up-down direction and the horizontal direction D (left-right direction).

[0039] As shown in Figures 5 to 7, screw holes 813a are formed in the receiving part side connecting plate 813, penetrating in the indoor / outdoor direction (projection direction). With the receiving part fitting 82 attached to the base fitting 81 and the relative position in the lateral direction D (left-right direction) adjusted, two screws 802 inserted into the elongated holes 821a of the receiving part connecting plate 821 of the receiving part fitting 82 are tightened into the screw holes 813a. In this way, the two screws 802 fix the base fitting 81 and the receiving part fitting 82 with the relative position in the lateral direction D (left-right direction) adjusted.

[0040] 2, receiving fitting 82 is fixed to receiving portion-side connecting plate 813 of base fitting 81 with screws 802 after its left-right position relative to base fitting 81 has been adjusted.

[0041] As shown in Figures 2, 4 to 7, the receiving part fitting 82 has a receiving part connecting plate 821 (vertical extending portion, base side fixed portion) formed on one side D1 in the horizontal direction D of the receiving part fitting 82, a pair of protruding plates 822, 822 (protruding portion, guide portion) formed on the upper and lower ends of the receiving part connecting plate 821, an inclined connecting portion 823 (step connecting portion) connected to the other side D2 in the horizontal direction D of the receiving part connecting plate 821, and a crescent engaging portion 824 connected to the end of the other side D2 in the horizontal direction D of the inclined connecting portion 823.

[0042] The receiving portion connecting plate 821 is formed on one side D1 in the lateral direction D of the receiving portion fitting 82, and is fixed to the base fitting 81 with screws 802. The receiving portion connecting plate 821 is arranged along the indoor side X2 surface of the receiving portion side connecting plate 813 of the base fitting 81. The receiving portion connecting plate 821 is formed in the shape of a flat plate that extends in the vertical direction and the lateral direction D (left and right direction). The receiving portion connecting plate 821 is arranged in a position where at least a portion overlaps the receiving portion side connecting plate 813 of the base fitting 81 in a front view.

[0043] As shown in Figures 6 and 7, the receiving portion connecting plate 821 is formed with a pair of elongated holes 821a that penetrate in the indoor / outdoor direction (projection direction). The pair of elongated holes 821a are formed spaced apart in the up-down direction, and each elongated hole extends in the lateral direction D (left-right direction). Screws 802 are inserted into the pair of elongated holes 821a. By extending in the left-right direction (lateral direction), the elongated holes 821a can move in the lateral direction D (left-right direction) along the screws 802.

[0044] 4 and 5, screws 802 are inserted into the pair of elongated holes 821a from the indoor side X2, and the shanks 802b of the screws 802 are threaded into the screw holes 813a of the receiving-side connecting plate 813 of the base fitting 81 to fasten the base fitting 81. The screws 802 pass through the base fitting 81 and the receiving fitting 82 in the indoor-outdoor direction to fasten the base fitting 81. In this way, the screws 802 that pass through the two elongated holes 821a, 821a are fastened into the screw holes 822a, so that the receiving fitting 82 is fastened to the base fitting 81 with its position in the lateral direction D (left-right direction) adjusted relative to the base fitting 81.

[0045] 2, the screw 802 has a head 802a, a shaft 802b, and a tip 802c. The head 802a of the screw 802 is arranged on the surface of the receiving part connecting plate 821 on the indoor side X2. The shaft 802b of the screw 802 extends in the indoor-outdoor direction and is arranged to pass through the receiving part side connecting plate 813 and the receiving part connecting plate 821, and is fastened to a screw hole 813a in the receiving part side connecting plate 813 of the base metal fitting 81. The tip 802c of the screw 802 is arranged to protrude from the receiving part side connecting plate 813 towards the outdoor side X1.

[0046] The pair of protruding plates 822, 822 protrude from the upper and lower ends of the receiving portion connecting plate 821 toward the outside side X1 and extend in the lateral direction D (left and right direction). The receiving portion connecting plate 821 and the pair of protruding plates 822, 822 are integrally formed. The pair of protruding plates 822, 822 regulate the position of the base metal fitting 81 in the up and down direction.

[0047] The pair of protruding plates 822, 822 are arranged above and below the receiving part side connecting plate 813 when the receiving part side connecting plate 813 of the base metal fitting 81 is arranged on the outdoor side X1 surface of the receiving part connecting plate 821. In this way, the pair of protruding plates 822, 822 regulate the positions of the upper and lower ends of the receiving part side connecting plate 813, thereby regulating the vertical position of the receiving part side connecting plate 813.

[0048] The crescent engaging portion 824 is formed on one side D1 in the lateral direction D of the receiving metal fitting 82. The crescent engaging portion 824 is engageable with the crescent 7. The crescent engaging portion 824 engages with the crescent 7 to receive the crescent 7.

[0049] The crescent engagement portion 824 is connected to the receiving portion connecting plate 821 via the inclined connection portion 823. The crescent engagement portion 824 is connected to the end portion of the inclined connection portion 823 on the other side D2 in the lateral direction D. The crescent engagement portion 824 has a U-shaped portion 824a that is open on the base fitting 81 side, and a claw-shaped engagement portion 824b that protrudes toward the base fitting 81 at the tip of the U-shaped portion 824a.

[0050] The end of the U-shaped portion 824a on the outdoor side X1 of the U-shape is connected to the end of the inclined connecting portion 823 on the other side D2 in the lateral direction D. The claw-shaped engaging portion 824b is connected to the end of the U-shaped portion 824a on the indoor side X2 of the U-shape, and protrudes toward the base metal fitting 81. The hook member 73 of the crescent 7 can engage with the claw-shaped engaging portion 824b.

[0051] The inclined connection portion 823 connects the receiving portion connecting plate 821 and the crescent engagement portion 824. The inclined connection portion 823 constitutes a stepped connection portion that connects the receiving portion connecting plate 821 and the crescent engagement portion 824 with a step that is offset in the indoor / outdoor direction. The inclined connection portion 823 inclines from the indoor side X2 toward the outdoor side X1 as it moves from the receiving portion connecting plate 821 side toward the crescent engagement portion 824 side.

[0052] In the crescent receiver member 8 configured as described above, the receiver fitting 82 and base fitting 81 are temporarily fixed by inserting screws 802 into the elongated holes 821a of the receiver connecting plate 821 of the receiver fitting 82 and the screw holes 813a of the base fitting 81. In this state, by loosening the screws 802 inserted into the elongated holes 821a of the receiver connecting plate 821 of the receiver fitting 82 and the screw holes 813a of the base fitting 81, the receiver fitting 82, with the receiver-side connecting plate 813 guided by the pair of protruding plates 822, can move in the lateral direction D (left-right direction) relative to the base fitting 81 along the elongated holes 814a.

[0053] When adjusting the position of receiving fitting 82 in the lateral direction D (left-right direction), screw 802 is loosened and, with receiving part side connecting plate 813 guided by the pair of protruding plates 822, it is moved in the lateral direction D (left-right direction) along long hole 814a, thereby moving receiving fitting 82 in the lateral direction D (left-right direction) relative to base fitting 81. In this way, with the position of crescent engagement portion 824 of receiving fitting 82 adjusted in the lateral direction D (left-right direction), receiving fitting 82 can be fixed to base fitting 81 by tightening screw 802.

[0054] According to this embodiment, the following effects are achieved: The crescent receiving member 8 of this embodiment is provided at the joining portion 5 of the inner shoji screen 4 and the outer shoji screen 3, and is capable of engaging with the crescent 7, and comprises a base metal fitting 81 fixed to the vertical stile 34 of the outer shoji screen 3 at the joining portion 5, and a receiving part metal fitting 82 fixed to the base metal fitting 81 with its position relative to the base metal fitting 81 adjusted, and which engages with the crescent 7 to receive the crescent 7, and a pair of protruding plates 822 are formed on the upper and lower ends of the receiving part metal fitting 82 to regulate the position of the base metal fitting 81 in the up-down direction.

[0055] As a result, in this embodiment, the vertical position of the receiving metal fitting 82 is regulated by the pair of protruding plates 822, so that the vertical position is less likely to shift, and the part guided by the pair of protruding plates 822 can be positioned accurately without coming off.

[0056] Furthermore, since the pair of protruding plates 822 are not formed by drawing, they are easy to process. Therefore, in the crescent receiver member 8, which is composed of two pieces, the guided portion can be positioned with high precision without coming off easily, and processing is also easy. Furthermore, while a conventional structure in which guide walls are provided on the inside of the receiving metal fitting 82 is difficult to process, the present disclosure provides a pair of protruding plates 822 at the upper and lower ends of the receiving metal fitting 82, making processing easy.

[0057] Furthermore, in this embodiment, the receiving metal fitting 82 has a receiving part connecting plate 821 that extends in the vertical direction, and a pair of protruding plates 822 that protrude in the indoor / outdoor directions and are formed on the upper and lower ends of the receiving part connecting plate 821. This makes it possible to regulate the vertical position of the base metal fitting 81 with a simple configuration that only requires the provision of a pair of protruding plates 822.

[0058] In addition, in this embodiment, a screw 802 is provided that penetrates and fastens the base fitting 81 and the receiving fitting 82 in the indoor / outdoor direction, and the receiving fitting 82 has a receiving connecting plate 821 formed on one side D1 of the receiving fitting 82 in the horizontal direction D and connected to the base fitting 81, a crescent engaging portion 824 formed on the other side D2 of the receiving fitting 82 in the horizontal direction D and capable of engaging with the crescent 7, and an inclined connecting portion 823 that connects the receiving connecting plate 821 and the crescent engaging portion 824 with a step that is offset in the indoor / outdoor direction.

[0059] Therefore, when the base metal fitting 83 and the receiving metal fitting 82 are fixed with the screw 802, the receiving metal fitting 82 has an inclined connecting portion 823, so that it is possible to secure a gap (clearance) in which the screw 802 can be positioned so that its axial direction is along the indoor / outdoor direction while keeping the indoor / outdoor size of the crescent receiving member 8 compact. This makes it possible to form the indoor / outdoor size of the crescent receiving member 8 compact, and also prevents the tip 802c of the screw 802 from contacting the face material 35 of the outer shoji screen 3.

[0060] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

[0061] In the above embodiment, the pair of guide portions 822 (protrusions, protruding plates) are provided on the receiving portion 82 (receiving metal fitting), but this is not limiting. The pair of guide portions 822 (protrusions, protruding plates) may also be provided on the base portion 81 (base metal fitting).

[0062] In the above embodiment, the relative lateral positions of the receiving portion 82 (receiving metal fitting) and the base 81 (base metal fitting) are adjusted by providing the elongated hole 821a in the receiving portion 82 (receiving metal fitting), but this is not limiting. The relative lateral positions of the receiving portion 82 (receiving metal fitting) and the base 81 (base metal fitting) may also be adjusted by providing an elongated hole in the base 81 (base metal fitting).

[0063] Furthermore, in the above embodiment, the receiving metal fitting 82 is configured to have the inclined connecting portion 823, but this is not limitative, and the receiving metal fitting 82 may be configured without the inclined connecting portion 823. [Explanation of symbols]
