DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 4 show a first embodiment of the building material for openings of the present invention. This building material for openings is applied to a sliding window for a house, and as shown in Figures 1 and 2, it includes a frame 1 attached to an opening in a building frame, an outer screen 2 and an inner screen 3 provided in the frame 1 in a sliding manner so as to be freely opened and closed, and a screen door 30 provided on the outside of the outer screen 2 so as to be slidable along upper and lower frames 4 and 5.

[0008] As shown in Figures 1 and 2, the frame 1 is composed of an upper frame 4, a lower frame 5, and left and right vertical frames 6, 6 which are framed all around. The outer screen 2 is constructed by assembling an upper frame 9, a lower frame 10, a door end frame 11, and a joint frame 12 on all four sides, with double-glazed glass 13 fitted inside. The inner screen 3 is also constructed by assembling an upper frame 9, a lower frame 10, a door end frame 11, and a joint frame (vertical material) 14 on all four sides, with double-glazed glass 13 fitted inside. The frames of the inner and outer screens 2 and 3 are made of aluminum shaped material on the outside and plastic shaped material on the inside. When the inner and outer screens 2 and 3 are closed, the outer screen 2 is located on the left side as seen from inside the room, and the inner screen 3 is located on the right side as seen from inside the room. The outer screen 2 and the inner screen 3 are locked with a crescent 27 (see Figure 3) provided on the door frame 14.

[0009] As shown in Figure 2, the upper frame 4 and the lower frame 5 are made of an aluminum alloy extruded profile, and are connected by a resin insulating bridge material 16 to the outdoor exterior profile 28 and the indoor interior profile 29. The rails guiding the outer and inner screens 2 and 3 and the inner periphery of the indoor interior profile 29 are covered with a resin cover 17 to block heat transfer from the indoors to the outdoors and prevent condensation on the indoor side.

[0010] As shown in Figure 1, the left-hand vertical frame 6, seen from the inside of the room and located on the outer screen 2 side, is made of an extruded aluminum alloy material, and the part exposed to the interior side of the room beyond the door frame 11 of the outer screen 2 is covered with a plastic cover 18. This improves the insulation performance and prevents condensation on the interior side. By attaching the plastic cover 18 in this way, the door frame 11 of the outer screen 2 is hidden by the plastic cover 18. The vertical frame 6 on the right side when viewed from inside the room, located on the inner shoji screen 3 side, also has the part exposed to the inside of the room covered with a resin cover 18.

[0011] As described above, this opening construction material has a resin cover 18 attached to the vertical frame 6 on the left side when viewed from inside the room, and the door end frame 11 of the outer door screen 2 is hidden by the resin cover 18, so it is not possible to open the outer door screen 2 by placing a hand on the door end frame 11. Therefore, this opening construction material is provided with a handle 19 with a finger pinch prevention function on the door end end of the bottom frame 10 of the outer door screen 2 on the indoor side, as shown in Figures 1, 3, and 4. 4, the pull handle 19 includes a case 20 that is attached to the interior side of the bottom frame 10, and a stopper 8. The case 20 has a recessed handle 7 formed on the door end side. Stopper 8 is provided at a position adjacent to the trailing edge of handle 7. Stopper 8 is a block-shaped part made of resin, with the trailing edge side supported by a vertical shaft 21 and the trailing edge portion protruding from case 20. The protruding portion has a contact surface 22 provided on the trailing edge side parallel to the indoor / outdoor direction and a taper 23 provided so as to slope toward the outdoor side as it approaches the trailing edge. Stopper 8 is biased by a spring 24 in the direction in which the trailing edge portion protrudes from case 20.

[0012] The following describes the procedure for opening the outer door 2. As shown in FIG. 5-1(a), a finger is placed on the handle 7 of the pull tab 19 with a finger-pinch prevention function, and the outer door 2 is moved to the opening side. Then, as shown in Figure 5-1 (b), the abutment surface 22 of the stopper 8 abuts against the outer peripheral side surface of the joint frame 14 of the inner screen 3, and the outer screen 2 stops just before the fully open position. Then, as shown in FIG. 5-2(c), while pressing the protruding portion of the stopper 8 with one finger, use the other hand to push the door frame 11 from the door end side to move the outer door screen 2 to the opening side. Thereafter, as shown in FIG. 5-2(d), the joint frame 12 of the outer screen 2 abuts against the stopper 25 provided on the bottom frame 5, and the outer screen 2 stops (fully open position).

[0013] When closing the outer screen 2 in the fully open position, the door end frame 11 is grasped with the hands from both the outside and inside of the room, the outer screen 2 is pulled out slightly towards the door end, and then the outer screen 2 is closed by placing a hand on the inner circumference of the door end frame 11 or by placing a hand on the handle 7 of the finger-pinching prevention handle 19. When the outer screen 2 is closed, the stopper 8 of the finger-pinching prevention handle 19 retracts into the case 20 as the taper 23 abuts against the joint frame 14 of the inner screen 3, so that the movement of the outer screen 2 is not impeded.

[0014] In this way, this opening building material is equipped with a handle 19 with a finger pinch prevention function on the bottom frame 10 of the outer screen 2, so even if the door end frame 11 is hidden by the resin cover 18, the outer screen 2 can be opened by placing a hand on the handle 7 of the handle 19 with a finger pinch prevention function. At that time, the stopper 8 abuts against the door frame 14 of the inner screen 3, stopping the outer screen 2 just before it is fully open, so that fingers placed on the handle 7 can be prevented from being pinched between the door frame 10 and the door frame 14 of the inner screen 3. The inner shoji screen 3 can be opened and closed by placing one's hand on the frame 14.

[0015] 6 and 7 show a second embodiment of the construction material for openings of the present invention, which differs from the first embodiment in the structure of the pull tab 19 with finger pinch prevention function. As shown in Fig. 7, in the pull handle 19 of this embodiment, the stopper 8 and the handle 7 are integrally formed into one stopper / handle part 26. The stopper / handle part 26 is formed in a block shape from resin and is held in the case 20 so as to be movable in the indoor / outdoor direction, and is biased by a spring 24 in the direction in which it protrudes from the case 20. The stopper / handle part 26 has a contact surface 22 provided parallel to the indoor / outdoor direction on the door trailing edge side, and has a taper 23 and a concave-shaped handle 7 on the door leading edge side.

[0016] The following describes the procedure for opening the outer door 2. As shown in FIG. 8-1(a), place your finger on the handle 7 formed on the door end side of the stopper / handle part 26 and move the outer door 2 to the opening side. Then, as shown in Figure 8-1 (b), the abutment surface 22 formed on the end of the stopper / handle part 26 abuts against the outer peripheral side of the joint frame 14 of the inner screen 3, causing the outer screen 2 to stop just before the fully open position. Then, as shown in FIG. 8-2(c), while pressing the stopper / handle part 26 with one finger, use the other hand to push the door frame 11 from the door end side, thereby moving the outer door screen 2 to the opening side. Thereafter, as shown in Figure 8-2 (d), the joint frame 12 of the outer screen 2 abuts against the stopper 25 provided on the bottom frame 5, and the outer screen 2 stops (fully open position). When the outer screen 2 is closed, the taper 23 of the stopper / handle part 26 abuts against the joint frame 14 of the inner screen 3, causing the stopper / handle part 26 to retract, so that the closing operation of the outer screen 2 is not hindered.

[0017] Although the above explanation is for sliding windows, the present invention can also be applied to single-sliding sashes with a single shoji screen and a door pocket. In that case, when the shoji screen 2 is opened, the stopper 8 comes into contact with the mullion (vertical member) that is provided opposite the interior side of the joint frame 12 when the shoji screen 2 is closed, and the shoji screen 2 stops just before it reaches the fully open position.

[0018] As described above, the first and second embodiments of the opening construction material include a frame 1 and a shoji (outer shoji) 2. The shoji 2 slides along the upper and lower frames 4 and 5. It has a handle 7 and a stopper 8 on the door end side on the indoor side. When the handle 7 is put on and the shoji 2 is moved to the opening side, the stopper 8 comes into contact with the vertical member (the inner shoji 3's joint frame 14, the mullion) that faces the indoor side of the joint frame 12 of the shoji 2, and the shoji 2 stops just before it is fully open. The shoji 2 can be fully opened by releasing the stopper 8 (see Figures 1 and 6). This makes it easy to open the shoji 2 and also prevents fingers from getting pinched between the vertical member 14 and the stopper 8. In this construction material for openings (first embodiment), the stopper 8 is provided at a position adjacent to the end of the door handle 7 (see Figure 4), which reliably prevents fingers from getting pinched and also makes it easy to release the stopper 8. In this opening building material (second embodiment), the handle 7 and stopper 8 are integrally constructed as a single part (stopper / handle part) 26 (see Figure 7), which simplifies the structure, resulting in a neater appearance and improved design and operability. In this opening building material (first and second embodiments), the stopper 8 is provided so as to be able to protrude and retract from the interior side of the shoji screen 2 and is biased in the protruding direction (see Figures 4 and 7), so that the shoji screen 2 can be securely stopped by the stopper 8 when it is opened, and the stopper 8 can also be easily released. In this opening building material (first and second embodiments), the stopper 8 is provided with a taper 23 so that it abuts against the upright 14 and retracts when the screen 2 is moved from the fully open position to the closed side, so that the stopper 8 does not interfere with the closing operation of the screen 2, making it easy to operate.

[0019] The present invention is not limited to the above-described embodiment. The shape and material of the handle and stopper can be changed as appropriate. The structure of the frame and the shoji is not important. The present invention can be applied to sliding sashes and single sliding sashes, as well as sashes with three or four shoji panels.
