As shown in FIGS. 7 and 9, the lower guide mechanism 60 includes a sliding member 61 attached to the exterior facing piece 421 of the lower frame 42 and a lower rail 221 attached to the projection piece 222 of the lower frame 22. and a drawing member 64 applied to the outdoor surface of the. The sliding member 61 and the attracting member 64 are each made of a resin material.
The sliding member 61 has a protruding portion that protrudes into the room. The sliding member 61 is fitted in a notch portion formed in the central portion in the longitudinal direction of the exterior appearance piece 421 of the lower rail 42, and the projecting portion thereof projects from the exterior appearance piece 421 toward the interior side. It is
The pulling member 64 is arranged at a position where the outdoor-side vertex thereof faces the indoor-side vertex of the protrusion of the sliding member 61 when the opening 20 is fully closed.
In this lower guide mechanism 60 , the sliding member 61 moves in the X-axis direction with respect to the pulling member 64 as the shoji 4 slides. When the shoji 4 moves from the fully closed position to the door bottom side at a predetermined distance, the projecting portion of the sliding member 61 is in a non-contact state with the drawing member 64, so that the lower guide The mechanism 60 does not draw and guide the shoji 4 to the outdoor side. Further, when the shoji 4 moves to a position closer to the door than the remote position, the protruding portion of the sliding member 61 is in contact with the drawing member 64. Therefore, the lower guide mechanism 60 draws and guides the shoji 4 to the outdoor side.

As shown in FIGS. 8 and 10, the upper guide mechanism 50 includes left and right sliding members 52 attached as cap members to the upper ends of the vertical frames 43 and 44, and left and right recessed members 55 attached to the upper rail 211. It has Each recessed member 55 is attached to a cutout portion of the upper rail 211 . The sliding member 52 and the recessed member 55 are each made of a resin material.
As shown in FIG. 10, each of the left and right sliding members 52 has a pair of side piece portions 521 and 522 and a bottom piece portion 523 to form a groove portion 524. connected in the axial direction. The side piece portion 522 located on the indoor side with respect to the side piece portion 521 is formed with a protruding portion 525 that protrudes to the outdoor side.
The left and right recessed members 55 are formed with recessed portions 551 recessed toward the exterior side of the vehicle. ing.
In the upper guide mechanism 50, the left and right sliding members 52 move in the X-axis direction with respect to the left and right recessed members 55 as the shoji 4 slides. When the shoji 4 moves from the fully closed position toward the door bottom side at a predetermined distance, the projections 525 of the left and right sliding members 52 slide on the upper rails 211 to guide the shoji 4 in the X-axis direction. . Further, when the shoji 4 moves to a position closer to the door than the remote position, the projecting portions 525 of the left and right sliding members 52 enter the recessed portions 551 of the left and right recessed members 55 . As a result, the shoji 4 can be drawn toward the outdoor side by the drawing mechanism described above.

The airtight material 10 described above is made of resin, and as shown in FIGS. and an annular airtight material contact portion 12 . FIG. 11(A) shows the airtight material 10 in a state not crushed by the shoji 4, and FIG. 11(B) shows a state crushed by the shoji 4. As shown in FIG. The airtight material base portion 11 includes a flat plate-like body base portion 111 having the airtight material contact portion 12 attached to the surface thereof, an engaging claw portion 112 extending from the back surface of the body base portion 111 , and one side of the surface of the body base portion 111 . and a protrusion 113 protruding from the edge side. A gap 114 is provided between the projecting portion 113 and the airtight material contact portion 12 to allow crushing deformation of the airtight material contact portion 12 within a predetermined range. The projecting portion 113 has a receiving surface 113</b>A that faces the side portion of the airtight material contact portion 12 . The receiving surface 113A is inclined with respect to the direction A in which the projecting portion 113 protrudes so that the tip of the receiving surface 113A is positioned farther from the airtight material contact portion 12 than the base end. If sand or water gets over the airtight material contact portion 12 and enters, these can be guided to the drainage path. The projecting dimension 115 of the projecting portion 113 in the A direction is smaller than the dimension 116 of the airtight material contacting portion 12 in the A direction, and the airtight material contacting portion 12 is attached to the shoji 4 as shown in FIG. 11(B). The size is large enough not to interfere with the shoji 4 when it is pushed and crushed by a predetermined amount (in this embodiment, when it is crushed by about 4 mm). If, for example, there is a construction error or a warpage occurs in the member to which the airtight material 10 is attached, the projection 113 may come into contact with the shoji 4, but this contact causes the airtight material contact part 12 to become excessively large. It is possible to suppress the occurrence of permanent compression strain due to being crushed.
The airtight member 10 thus formed is attached to the attaching piece portion 253 with the engaging claw portion 112 engaged with the engaging concave groove 254 of the central rib 25 . At this time, the projecting portion 113 is arranged on the smoke return piece portion 252 side with respect to the airtight material contact portion 12 .
Further, another airtight member 10 formed in the same manner as described above is attached to the upper frame 21, the lower frame 22 and the vertical frame 23 (attachment tab portion 201). The ends of each airtight member 10 are butted against each other, thereby surrounding the opening 20 . Further, the protrusion 113 of the airtight material base portion 11 is arranged on the outer peripheral side with respect to the airtight material contact portion 12 . Therefore, the formation of pinholes between the ends of the airtight members 10 due to elastic deformation of the airtight member abutting portions 12 toward the outer peripheral side is suppressed.

As shown in FIG. 12, the pull tab 8 described above has two finger hooking grooves 81 and 82 having different top and bottom shapes. 13A is a cross-sectional view of the finger hooking groove portion 81, and FIG. 13B is a cross-sectional view of the finger hooking groove portion 82. FIG.
The finger hooking grooves 81, 82 are formed by bottom surfaces 83A, 83B, side surfaces 84A, 84B (finger hooking surfaces), and inclined side surfaces 85A, 85B (finger guide surfaces). The inclined side surfaces 85A and 85B are inclined with respect to the direction B (left and right direction of the handle 8) so that the finger hooking grooves 81 and 82 become shallower as they move away from the bottom surfaces 83A and 83B. there is
The finger hooking grooves 81 and 82 are formed in opposite directions. In the finger hooking groove portion 81, the side surface 84A is positioned on the front side of the door and the inclined side surface 85A is positioned on the bottom side of the door when the handle 8 is installed on the vertical frame 43. As shown in FIG. For this reason, the finger hooking groove portion 81 is configured as a finger hooking groove portion for the closing movement operation, and becomes shallower from the door tip side toward the door bottom side. Further, finger hooking groove portion 82 located below finger hooking groove portion 81 has side surface 84B located on the door bottom side and inclined side surface 85B located on the door tip side when pull tab 8 is installed on vertical frame 43 . For this reason, the finger hooking groove portion 81 is configured as a finger hooking groove portion for the opening movement operation, and becomes shallower from the door bottom side toward the door tip side.

In the single sliding window 1 described above, when the opening 20 is fully closed, the vertical frame 44 on the side of the door bottom is arranged to face the central frame 25 in the Z-axis direction. The dimension L1 of the estimated interval 28 between the mounting piece 253 of the central rib 25 and the facing surface 443 of the vertical frame 44 facing the mounting piece 253 in this state is the operator's finger 15 ( 3 and 4), and is set to 9 mm in this embodiment.
In addition, when the opening 20 is fully opened (see FIG. 5), the vertical frame 43 on the front end side of the door is arranged to face the central frame 25 in the Z-axis direction. The dimension L2 of the estimated space 29 between the attachment piece 253 of the central rib 25 and the exterior appearance piece 431 of the vertical frame 43 in this state is set to be larger than the finger width dimension described above. Here, the finger width dimension is set based on the ASTM standard (ASTM: American Society for Testing and Materials (American Society for Testing and Materials)), and the dimension L2 is set to 13 mm or more, and 13 mm in this embodiment (ASTM F 963-03 "Do not pinch fingers of children under 8"). In the above-mentioned ASTM standard, the finger width dimension of the fingers 15 of children under 8 years old is assumed, but not limited to this, the finger width dimension of the fingers 15 of 8 years old or older is the finger width dimension in this embodiment. may be Also in this case, the dimension L2 is set to be larger than the finger width dimension.

The opening operation of the single sliding window 1 according to this embodiment is as follows.
First, as shown in FIG. 3, the finger 15 is put on the side surface 84B of the finger hooking groove 82 of the handle 8 of the shoji 4 in the closed position, and then the shoji 4 is opened toward the door bottom. Due to this opening movement, the sliding member 61 of the lower guide mechanism 60 is disengaged from the drawing member 64 in the X-axis direction and comes into slidable contact with the lower rail 221 . deviates from the recessed portion 551 of the recessed member 55 in the X-axis direction and slidably contacts the upper rail 211 , and the engaging member 442 is detached from the smoke return piece portion 252 . At this time, the tilting door roller 46 returns from the tilted state to the upright state by the weight of the shoji 4 itself. By moving to open in this manner, the drawing to the outdoor side by the drawing mechanism is released, and the shoji 4 moves about 4 mm to the indoor side in the Z-axis direction and is separated from the airtight material 10 .
When the shoji 4 is continuously moved to open, the vertical frame 43 on the front side of the door begins to overlap the central frame 25 in the projection direction as shown in FIG. At this time, the estimated distance 29 between the attachment piece 253 of the middle rib 25 and the exterior appearance piece 431 of the vertical frame 43 is L2 of 13 mm or more in the Z-axis direction as described above. and the vertical frame 43, a finger relief space is formed. Here, even if the finger 15 enters between the middle rib 25 and the vertical frame 43, the airtight material 10 attached to the attachment piece 253 functions as a cushioning material and the finger 15 escapes into the finger escape space. is pinched and crushed between the central rib 25 and the vertical frame 43, thereby reducing the risk of pinching a finger. Also, even if the timing of pulling out the finger 15 from the handle 8 is delayed, the finger 15 is pulled out to the outdoor side while being guided by the inclined side surface 85B of the finger hooking groove 82.例文帳に追加
Finally, by inertial movement of the shoji 4 or pushing the vertical frame 43 toward the door bottom side, the shoji 4 is placed at the fully open position shown in FIG. 5, and the opening 20 is fully opened. At the fully open position, the shoji 4 is housed on the indoor side of the fixed window 3 without leaving any gaps, and the edge of the door edge of the exterior paneling piece 431 and the interior paneling piece 434 of the vertical frame 43 is aligned with the central frame 25. Since it is positioned on an imaginary straight line along the prospective surface 255 that defines the opening 20 , the vertical frame 43 is arranged so as not to protrude toward the opening 20 from the central rib 25 . Thus, the shoji 4 is placed in the fully open position shown in FIG. 5 and the opening 20 is opened to the maximum.

The closing operation of the single sliding window 1 according to this embodiment is as follows.
First, as shown in FIG. 5, the operation handle 9 of the shoji 4 in the fully open position, the exterior facing piece 431 of the vertical frame 43, the interior facing piece 434, etc. are grasped by hand, and the shoji 4 is pulled out toward the door. 8 appears in the opening 20, the finger 15 is hooked on the side surface 84A of the finger hooking groove 81, and the shoji 4 is moved toward the door leading edge.
When the shoji 4 is continuously moved to close, the guide mechanism 5 draws the shoji 4 toward the outdoor side. Specifically, the projection 525 of the sliding member 52 of the upper guide mechanism 50 enters the recessed portion 551 of the recessed member 55 so that the shoji 4 can move to the outside of the room, while the slide of the lower guide mechanism 60 The moving member 61 abuts the pulling member 64, the pulling surface 91 of the front side pulling mechanism 90 formed at the tip of the lock member 71 abuts the tip of the lock receiving 72, and the engaging member A attracting surface 96 of a door tail side attracting mechanism 95 formed at the tip of 442 contacts the tip of the smoke return piece 252 . When the shoji 4 is moved to close in this state, the shoji 4 is moved about 4 mm toward the outdoor side by the lower guide mechanism 60 , the leading edge side pulling mechanism 90 and the trailing side pulling mechanism 95 . At this time, the tilting door roller 46 changes from the upright state to the tilted state, and the upper frame 41, the lower frame 42, and the left and right vertical frames 43, 44 are pressed against the airtight material 10 and closely attached. Thus, the shoji 4 is placed in the fully closed position shown in FIG. 3 and the opening 20 is closed.

[Summary of the present invention]
A fitting of the present invention is a fitting comprising a frame and a shoji slidably arranged in the frame in the horizontal direction, wherein the frame comprises an upper frame, a lower frame, and one side vertical frame. and the other side vertical frame, a vertical member is arranged between the one side vertical frame and the other side vertical frame, and an opening is formed by the upper frame, the lower frame, the one side vertical frame and the vertical member A part is formed, and the vertical member has a smoke return piece facing the shoji in the direction of projection of the fitting and a mounting piece to which an airtight material is mounted, and the mounting piece is arranged in the left-right direction The shoji is arranged closer to the opening than the smoke return piece, and the shoji includes a frame body composed of an upper frame, a lower frame, a vertical door frame, and a vertical frame at the door end, and a surface arranged in the frame. In the vertical member, at least in a state in which the vertical door frame faces the vertical member, the mounting piece part is separated from the vertical door frame by an expected interval larger than the finger width dimension. It is characterized by being configured to be located.
According to the fitting of the present invention, in a state in which the vertical door frame faces the vertical member, the attachment piece of the vertical member is positioned with an estimated gap larger than the finger width dimension with respect to the vertical door frame. A finger escape space is formed between the attachment piece and the vertical door frame. Therefore, for example, even if a finger for opening the door top stile is inserted between the mounting piece of the vertical member and the door top stile, the finger can be escaped into the finger escape space described above. It is possible to reduce the risk of fingers being caught between the vertical member and the door frame. In addition, the presence of the above-described smoke return piece can prevent fingers from being deeply inserted between the vertical member and the door frame. Furthermore, the airtight material attached to the attachment piece can exert a function as a cushioning material against fingers. In addition, it is only necessary to configure the vertical member so that the estimated interval between the mounting piece portion and the door top vertical stile is larger than the finger width dimension. There is no need to increase the expected dimensions of the frame.

In the fitting of the present invention, when the opening is fully open, the vertical door frame may not protrude further toward the opening than the vertical member.
According to such a configuration, by arranging the shoji to the fully open position by the opening movement, the effective opening area of the opening can be increased compared to, for example, the case where the vertical door frame protrudes toward the opening than the vertical member. can take

In the fitting of the present invention, a pulling mechanism may be configured between the frame and the shoji for moving the shoji toward the longitudinal member when the shoji is closed.
According to such a configuration, when the opening is opened and the vertical member and the door top vertical stile are opposed to each other, the finger width dimension between the mounting piece of the vertical member and the door top vertical stile is as described above. While it is possible to reduce the risk of finger pinching by forming an expected gap larger than that, when the opening is closed and the vertical member and the door bottom vertical frame face each other, the shoji is approached to the vertical member side by the pulling mechanism. Therefore, the door end vertical frame can be brought into close contact with the airtight material attached to the attachment piece, and airtightness can be maintained.

In the joinery of the present invention, an engagement groove is formed in the attachment piece of the vertical member, and the airtight material attached to the attachment piece includes an airtight material base that engages with the engagement groove. and an elastically deformable airtight material contact portion that contacts the shoji, and the part of the airtight material base that is located on the smoke return piece side with respect to the airtight material contact portion includes the fitting A projecting portion projecting to the shoji side in the direction of projection may be formed.
According to such a configuration, even if the shoji abuts against the airtight material contact portion and is elastically deformed, the airtight material contact portion can be received by the protrusion of the airtight material base portion. Excessive deformation of the material contact portion can be suppressed. As a result, the shoji can be brought into close contact with the airtight material abutting portion, and the airtightness can be maintained.

In the fitting of the present invention, a pull tab is provided on the opening piece of the vertical door stile facing the vertical member, and the pull tab is for opening and moving operation that becomes shallower from the door bottom side toward the door top side. may have finger hooking grooves.
According to such a configuration, the shoji can be easily opened and moved by putting a finger on the finger-hanging groove of the handle, and when the door frame overlaps with the vertical member in the opening movement of the shoji, the finger can be pulled from the finger-hanging groove. Even if the pull-out timing is delayed, as described above, since the finger-hanging groove becomes shallower from the door bottom side to the door tip side, it can be pulled out from the finger-hanging groove and guided. It is possible to reduce the risk of pinching a finger between the handle and the vertical member.

In the fitting of the present invention, the pull tab may further have a finger hooking groove for closing movement operation that becomes shallower from the door tip side toward the door bottom side.
According to such a structure, the shoji can be easily closed and moved by putting a finger in the finger-holding groove for the closing movement operation, and the finger-holding groove becomes shallower from the door tip side toward the door bottom side. Since it is configured such that it is difficult for the operator to move the shoji to the open position, it is difficult for the operator to misplace his/her fingers when operating the shoji to open it. For this reason, it is possible to reduce the risk of fingers being caught between the finger hooking groove for closing movement operation and the vertical member when opening the shoji.

In the fittings of the present invention, a pull is provided on the side edge portion of the vertical door frame facing the vertical member, and the pull is rotatable around the groove of the pull and an axis extending in the vertical direction. It may be configured by a rotating plate installed in the handle groove. According to such a configuration, when the sliding door is moved to open, a finger is inserted into the door trailing edge side portion of the handle groove to rotate the rotating plate. It is possible to form a shallow finger hooking groove for opening movement operation. In addition, when the shoji is closed and moved, inserting a finger into the door tip side of the handle groove to rotate the rotating plate causes the closing movement operation to become shallower from the door tip side to the door bottom side. finger hooking groove can be configured.
