DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 5 show one embodiment of a fitting of the present invention. This fitting is a shoji screen for a sash window, and as shown in Figure 5, is constructed by assembling upper and lower horizontal frames 1,1 and left and right vertical frames 2,2 in a rectangular shape so as to surround the periphery of glass (double glazing) 7. One-side connecting parts 3 are attached to both longitudinal ends of the horizontal frames 1,1, and other-side connecting parts 4 are attached to both longitudinal ends of the vertical frames 2,2. In this fitting, the horizontal frame 1 and the vertical frame 2 are connected by the one-side connecting part 3 and the other-side connecting part 4. The other-side connecting part 4 also serves as an end cap that covers the end of the upper and lower ends of the vertical frame 2.

[0010] As shown in Figure 1(c), the stile 1 is constructed by combining an aluminum extrusion 8 placed on the exterior side of the room with a plastic extrusion 9 placed on the interior side, and both extrusions 8, 9 form a glass holding groove 10 that is open on the inner periphery. The aluminum extrusion 8 and plastic extrusion 9 each have hollow sections 11, 12. The plastic extrusion 9 has a step 14 on the interior wall 13 on the inner periphery side of the hollow section 12. As shown in Figure 3, the stile 1 has a longitudinal end face 15 cut straight and perpendicular. The inner wall of the aluminum extrusion 8 has a square hole 17 into which the claw 16 of the one-side connecting part 3 engages.

[0011] The first connecting part 3 is made of hard resin and is formed in a block shape to fit into the hollow portion 11 of the aluminum extrusion 8 of the stile 1, as shown in Figures 1 to 3 and 7. As shown in Figure 4, the underside of the first connecting part 3 (or the upper surface if it is attached to the lower stile 1) has a right-angled triangular claw 16 that protrudes downward (or upward if it is attached to the lower stile 1), and when the first connecting part 3 is fitted into the hollow portion 11 of the stile 1 from the small end, the claw 16 engages with a square hole 17 in the stile 1, restricting the movement of the first connecting part 3 in the longitudinal direction of the stile 1. Furthermore, the first connecting part 3 has an engagement part 5 that protrudes from the end face 15 of the stile 1, as shown in Figures 2 and 3. The engaging portion 5 consists of a pair of claws 18, 18 spaced apart in the projection direction, and each claw 18 is bent outward at the middle in the left-right direction and then bent diagonally inward, with the tip 18a bent inward at a right angle.

[0012] As shown in Figures 2 and 3, the vertical frame 2, like the horizontal frame 1, is constructed by combining an aluminum profile 19 arranged on the exterior side and a plastic profile 20 arranged on the interior side, and both profiles 19, 20 form a glass retaining groove 10 that is open on the inner periphery. The aluminum profile 19 and the plastic profile 20 each have hollow sections 21, 22. As shown in Figure 3, the interior wall 23 of the plastic profile 20 has a notch 24 so as to abut against the step 14 of the interior wall 13 of the horizontal frame 1. Furthermore, as shown in Figures 1 and 4, the vertical frame 2 has notches 27a, 27b in an inward protrusion 26a formed on the inner periphery end of the exterior wall 25 of the aluminum profile 19 and in an inward protrusion 26b formed on the inner periphery end of the interior wall 23 of the plastic profile 20. In addition, the inner peripheral side wall of the vertical frame 2 on the aluminum profile 19 side is formed with a notch 28 to receive the engaging portion 5 of the one side connecting part 3 and a square hole 30 to which the claw 29 of the other side connecting part 4 engages.

[0013] As shown in Figures 1 to 3, the longitudinal end of the horizontal frame 1 is inserted into the glass retaining groove 10 of the vertical frame 2, and the end face 15 abuts against the inner peripheral side surface 31 of the vertical frame 2. As shown in Figure 1, the longitudinal end of the horizontal frame 1 fits between the outdoor wall 25 and the indoor wall 23 of the vertical frame 2, and the step portion 14 and the inner peripheral side edge of the horizontal frame 1 engage with the notches 24, 27a, 27b formed in the vertical frame 2, so that the longitudinal end of the horizontal frame 1 and the longitudinal end of the vertical frame 2 are engaged in a state in which movement in the projection direction and in the inner and outer peripheral directions is restricted.

[0014] The other connecting part 4 is made of hard resin and, as shown in Figures 1, 3, 4, and 7, has an end closing portion 32 that closes the end of the vertical stile 2, an exterior fitting portion 33 that fits into the hollow portion 21 on the aluminum section 19 side of the vertical stile 2, an interior fitting portion 34 that fits into the hollow portion 22 on the plastic section 20 side of the vertical stile 2, and an engaged portion 6 that is located inside the exterior fitting portion 33 and engages with the engaging portion 5 of the one connecting part 3. As shown in Figure 4, the exterior fitting portion 33 has a notch 35 in its inner wall and a right-angled triangular claw 29 that protrudes inward from the exterior of the notch 35. The engaged portion 6 has a columnar insertion portion 36 with a substantially T-shaped cross section, and a tapered portion 37 at the lower end of the insertion portion 36. As shown in Figure 2, the other connecting part 4 is attached by fitting the outdoor fitting part 33 and the indoor fitting part 34 into the hollow parts 21, 22 of the stile 2. When fitted, the claws 29 engage with square holes 30 formed in the stile 2 to prevent them from coming out, and the engaged part 6 (insertion part 36) is inserted into the engaging part 5 (between the inwardly curved parts at the tips of the pair of claw pieces 18, 18) of the one connecting part 3, thereby fixing the end face 15 of the horizontal stile 1 in a state where it is pulled against the inner peripheral side surface 31 of the stile 2. The outer peripheral side surface 38 of the outdoor fitting part 33 abuts against the outer peripheral side wall 39 of the stile 2, thereby restricting the tilt of the stile 2.

[0015] As shown in FIG. 5, the glass 7 is attached with its peripheral edge held in the glass holding grooves 10 of the horizontal frames 1,1 and vertical frames 2,2 via a glazing channel 40.

[0016] Next, we will explain how to assemble this fitting. First, as shown in Figure 6(a), one-side connecting parts 3 are fitted into hollow parts 11 on the aluminum extrusion 8 side at both ends of the horizontal stile 1 in the longitudinal direction. Next, as shown in Figure 6(b), the engaging portion 5 of the connecting part 3 on one side is inserted from above and below into the notch 28 formed in the vertical frame 2, and the longitudinal end of the horizontal frame 1 is inserted into the glass holding groove 10 of the vertical frame 2. Then, as described above, the longitudinal end of the horizontal frame 1 and the longitudinal end of the vertical frame 2 engage with each other in a state where movement in the projection direction and in the inner and outer circumferential directions is restricted, and the engaging portion 5 of the connecting part 3 on one side engages with the notch 28 of the vertical frame 2, so that the end face 15 of the horizontal frame 1 is restricted from moving away from the inner circumferential side surface 31 of the vertical frame 2. Then, as shown in Figure 6(c), when the other connecting part 4 is attached by fitting the outdoor fitting portion 33 and the indoor fitting portion 34 into the hollow portions 21, 22 of the vertical frame 2 from above and below, the engaging portion 5 of the one connecting part 3 and the engaged portion 6 of the other connecting part 4 engage with each other, and the two connecting parts 3, 4 become one unit, and the longitudinal end of the horizontal frame 1 and the longitudinal end of the vertical frame 2 are connected and fixed. In this way, the peripheral edge of the glass 7 is fitted into the glass retaining groove 10 of the horizontal frame 1 and vertical frame 2 via the glazing channel 40, and the four joints between the ends of the horizontal frame 1,1 and the vertical frame 2,2 are connected and fixed sequentially using the connecting parts 3 on one side and the connecting parts 4 on the other side, thereby making it possible to assemble the building fixture without using screws.

[0017] As described above, this fitting comprises one side member (horizontal stile) 1 and the other side member (vertical stile) 2 which are connected in a crosswise manner, one side connecting part 3 attached to the longitudinal end of the one side member 1, and the other side connecting part 4 attached to the longitudinal end of the other side member 2, the end face 15 of the one side member 1 abutting against the inner peripheral surface 31 of the other side member 2, the one side connecting part 3 is fitted into the hollow part 11 of the one side member 1 and attached, and has an engaging part 5 which protrudes from the end face 15 of the one side member 1, and the other side connecting part 4 is fitted into the hollow parts 21, 22 of the other side member 2 and attached, and has an engaged part 6 that engages with the engaging part 5 of the one side connecting part 3, therefore it can be easily assembled without using screws. Furthermore, in this fitting, the longitudinal end of one side member 1 and the longitudinal end of the other side member 2 are engaged in a state in which movement in the projection direction and in the inner and outer peripheral directions is restricted, thereby improving the connection strength between the one side member 1 and the other side member 2 and also improving the workability when connecting them. Furthermore, in this fitting, the other-side connecting part 4 has an abutment portion (the outer peripheral side surface 38 of the outdoor fitting portion 33) that abuts against the inner peripheral side wall or outer peripheral side wall 39 of the other-side member 2, thereby regulating the inclination of the other-side member 2 and improving the strength of the fitting. Furthermore, this fixture prevents the end face 15 of the one-side member 1 from moving away from the other-side member 2 by engaging the engagement portion 5 of the one-side connecting part 3 with the notch 28 of the other-side member 2, making assembly even easier and improving strength. The engaging portion 5 of the one-side connecting part 3 consists of a pair of claw pieces 18, 18 with inwardly bent tip ends, and the engaged portion 6 of the other-side connecting part 4 has an insertion portion 36 that is inserted between the pair of claw pieces 18, 18, so that the one-side connecting part 3 and the other-side connecting part 4 can be firmly engaged and integrated without any strain. The one-side connecting part 3 is attached to the one-side member 1 in advance in a state in which the movement of the one-side member 1 in the longitudinal direction is restricted, which further improves the ease of assembling the fitting. The other side connecting part 4 also serves as an end cap for covering the end of the other side member 2, so there is no need to provide a separate end cap, which reduces costs, and the fittings can be easily assembled by simply fitting the end cap and attaching the other side connecting part 4 to the end of the other side member 2.

[0018] The present invention is not limited to the above-described embodiments. The cross-sectional shapes and materials of the one-side member and the other-side member can be changed as appropriate. The one-side member and the other-side member can be any member that intersects and connects, and are not limited to stiles, but can also be frames, bars, etc. The shapes and materials of the one-side connecting part and the other-side connecting part can be changed as appropriate. The present invention is not limited to shoji screens, but can be applied to any type of fittings, such as sliding doors, doors, and window frames. [Explanation of symbols]
