The following describes an embodiment of the present invention with reference to the drawings. Figures 1 to 5 show one embodiment of the 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 to surround the periphery of the 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. This fitting connects the horizontal frame 1 and the vertical frame 2 with 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 ends of the upper and lower ends of the vertical frame 2.

As shown in Figure 1 (c), the horizontal frame 1 is constructed by combining an aluminum profile 8 arranged on the exterior side with a plastic profile 9 arranged on the interior side, and the two profiles 8, 9 form a glass holding groove 10 that is open on the inner circumference side. The aluminum profile 8 and the plastic profile 9 each have hollows 11, 12. The plastic profile 9 has a step 14 on the interior wall 13 on the inner circumference side of the hollow 12. As shown in Figure 3, the longitudinal end face 15 of the horizontal frame 1 is cut straight and perpendicular. The inner wall of the aluminum profile 8 has a square hole 17 into which the claw 16 of the one-side connecting part 3 engages.

The one-side connecting part 3 is made of hard resin and is formed in a block shape that fits into the hollow part 11 of the aluminum profile 8 of the cross frame 1, as shown in Figures 1 to 3 and 7. As shown in Figure 4, the underside (upper surface if attached to the lower cross frame 1) of the one-side connecting part 3 has a right-angled triangular claw 16 that protrudes downward (upper surface if attached to the lower cross frame 1), and when the one-side connecting part 3 is fitted into the hollow part 11 of the cross frame 1 from the small end, the claw 16 engages with a square hole 17 of the cross frame 1, restricting the movement of the one-side connecting part 3 in the longitudinal direction of the cross frame 1. The one-side connecting part 3 also has an engagement part 5 that protrudes from the end surface 15 of the cross frame 1, as shown in Figures 2 and 3. The engagement portion 5 consists of a pair of claw pieces 18, 18 spaced apart in the projection direction, and each claw piece 18 is bent outward at the middle in the left-right direction, then bent diagonally inward, with the tip 18a bent inward at a right angle.

As shown in Figures 2 and 3, the vertical frame 2 is constructed by combining an aluminum profile 19 arranged on the outside of the room and a plastic profile 20 arranged on the inside of the room, similar to the horizontal frame 1, and the two profiles 19, 20 form a glass holding groove 10 with an opening on the inner periphery side. The aluminum profile 19 and the plastic profile 20 each have hollows 21, 22. As shown in Figure 3, the indoor side wall 23 of the plastic profile 20 has a notch 24 so as to abut against the step 14 of the indoor side wall 13 of the horizontal frame 1. Furthermore, as shown in Figures 1 and 4, the vertical frame 2 has notches 27a, 27b in the inward protrusion 26a formed on the inner periphery side end of the outdoor side wall 25 of the aluminum profile 19 and the inward protrusion 26b formed on the inner periphery side end of the indoor side wall 23 of the plastic profile 20. In addition, the inner peripheral side wall of the vertical frame 2 on the aluminum section 19 side is formed with a notch 28 that receives the engagement portion 5 of the connecting part 3 on one side, and a square hole 30 into which the claw 29 of the connecting part 4 on the other side is engaged.

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 exterior wall 25 and the interior wall 23 of the vertical frame 2, and the step portion 14 and the inner peripheral edge of the horizontal frame 1 engage with the notches 24, 27a, and 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.

The other side connecting part 4 is made of hard resin, and as shown in Figs. 1, 3, 4 and 7, has a small end closing part 32 that closes the small end of the vertical frame 2, an outdoor fitting part 33 that fits into the hollow part 21 on the aluminum shaped material 19 side of the vertical frame 2, an indoor fitting part 34 that fits into the hollow part 22 on the plastic shaped material 20 side of the vertical frame 2, and an engaged part 6 that is disposed inside the outdoor fitting part 33 and engages with the engaging part 5 of the one side connecting part 3. As shown in Fig. 4, the outdoor fitting part 33 has a notch 35 on the inner peripheral wall, and a right-angled triangular claw 29 is formed protruding to the inner peripheral side at the outdoor side position of the notch 35. The engaged part 6 has a columnar insertion part 36 with a substantially T-shaped cross section, and a tapered part 37 is provided at the lower end of the insertion part 36.
As shown in Figure 2, the other-side 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, and when fitted, the claws 29 engage with square holes 30 formed in the vertical frame 2 to prevent it from coming out, and the engaged portion 6 (insertion portion 36) is inserted into the engaging portion 5 (between the inwardly curved portions at the tips of the pair of claw pieces 18, 18) of the one-side connecting part 3, thereby fixing the end face 15 of the horizontal frame 1 in a state where it is attracted to the inner peripheral side surface 31 of the vertical frame 2. The outer peripheral side surface 38 of the outdoor fitting portion 33 abuts against the outer peripheral side wall 39 of the vertical frame 2, thereby regulating the inclination of the vertical frame 2.

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

Next, a method of assembling this fitting will be described. First, as shown in Fig. 6(a), one-side connecting parts 3 are fitted into hollow parts 11 on the aluminum profile 8 side at both ends of the horizontal frame 1 in the longitudinal direction.
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 are engaged in a state in which 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 peripheral 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, so that the two connecting parts 3, 4 become one body, and the longitudinal end portion of the horizontal frame 1 and the longitudinal end portion of the vertical frame 2 are connected and fixed.
In this way, the peripheral portion 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, while the four joints between the ends of the horizontal frames 1, 1 and the vertical frames 2, 2 are sequentially connected and fixed using connecting parts 3 on one side and connecting parts 4 on the other side, thereby enabling the fitting to be assembled without using screws.

As described above, this fitting comprises a one-side member (horizontal frame) 1 and an other-side member (vertical frame) 2 which are connected in a cross-shaped manner, a one-side connecting part 3 attached to the longitudinal end part of the one-side member 1, and a other-side connecting part 4 attached to the longitudinal end part of the other-side member 2, with the end face 15 of the one-side member 1 abutting the inner peripheral side surface 31 of the other-side member 2, the one-side connecting part 3 being attached by fitting into the hollow portion 11 of the one-side member 1 and having an engaging part 5 protruding from the end face 15 of the one-side member 1, and the other-side connecting part 4 being attached by fitting into the hollow portions 21, 22 of the other-side member 2 and having an engaged part 6 which engages with the engaging part 5 of the one-side connecting part 3, therefore it can be easily assembled without using screws.
In addition, since 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 projected direction and in the inner and outer circumferential directions is restricted, the connection strength between the one side member 1 and the other side member 2 can be improved and the workability when connecting them is also improved.
Furthermore, in this fixture, the other-side connecting part 4 has a contact portion (the outer peripheral side surface 38 of the exterior fitting portion 33) that abuts against the inner peripheral side wall or the 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 fixture.
In addition, by engaging the engaging portion 5 of the connecting part 3 on one side with the notch 28 of the member 2 on the other side, this fitting prevents the end face 15 of the member 1 on one side from moving away from the member 2 on the other side, making assembly even easier and improving strength.
The engaging portion 5 of the connecting part 3 on one side consists of a pair of claw pieces 18, 18 with inwardly bent tip ends, and the engaged portion 6 of the connecting part 4 on the other side has an insertion portion 36 that is inserted between the pair of claw pieces 18, 18, so that the connecting part 3 on one side and the connecting part 4 on the other side can be firmly engaged with each other without any difficulty and integrated.
Since the one-side connecting part 3 is attached to the one-side member 1 in advance in a state in which the longitudinal movement of the one-side member 1 is restricted, the ease of assembly of the fixture is further improved.
The other side connecting part 4 also serves as an end cap for covering the end of the other side member 2, eliminating the need to provide a separate end cap, reducing costs, and the fitting can be easily assembled by simply attaching the other side connecting part 4 to the end of the other side member 2 by fitting the end cap.

The present invention is not limited to the above-described embodiment. The cross-sectional shape and material 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 anything that crosses and connects, and are not limited to frames, but can also be frames or bars. The shape and material 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.
