Description

  The present invention relates to a synthetic resin sash, and more particularly, to an improvement of a summon bowl for internal and external shoji.

  An internal and external shoji made by combining a synthetic resin upper and lower frame and a left and right vertical frame in a square shape in a frame made of a vertical frame and a left and right vertical frame framed in a square shape. In the synthetic resin sash, for the purpose of reducing the manufacturing cost of the internal and external shoji, the saddle material having the same cross-sectional shape is commonly used for all the upper, lower, left and right ridges (for example, Patent Documents 1, 2, and 4). 3).

  In that case, at least the lower arm must be provided with a recessed portion that opens downward for mounting the door carriage and for fitting the rail of the lower frame, and the holding form for the upper frame of the upper arm is the rail of the upper frame. If it is a form which fits, it is necessary to provide the upper collar also with the recessed part opened upwards.

  For this reason, the commonly used brazing material generally has a recess on one end side in the finding direction. Accordingly, all of the assembled internal and external shojis have a recess that opens to the outer peripheral surface. The upper and lower vertical recesses are used for the installation of doors and / or rails and are not exposed to the outside when they are housed in the frame. The recess of the mating rod is exposed to the outside even when the shoji is closed. Usually, in the case of a plastic shoji, the upper and lower, left and right ridges are joined at right angles by cutting both ends in the longitudinal direction by 45 degrees, butting the cut surfaces and welding them. In addition, in order to reinforce the mechanical strength of each ridge, a metal reinforcement member may be inserted into the ridge, and a screw may be screwed into the reinforcement member from the bottom of the recess to fix the ridge to the reinforcement member. Therefore, if the recess of the summon bowl remains open to the outside, not only the recess itself but also screws and the like will affect the appearance of the shoji, so a cover member covering the recess is fitted (patent) Literature 1, 2, 3).

Moreover, since it is necessary to ensure watertightness and airtightness in the summoning section in the closed state of the shoji, the summoning bowl is provided with smoke return on the faces (summing face) where the summoning bowl faces each other. However, since this smoke return is not necessary for the vertical fence on the door end side, smoke return is not provided for the commonly used firewood. Therefore, a smoke return member formed separately is fixed to a conventional plastic resin shoji summon with screws or the like (Patent Documents 1, 2, and 3).

  As described above, a cover member that covers the concave portion of the end face is fitted to the summing bowl in the conventional resin sash, and the smoke return member is fixed to the summing face. Therefore, since it is necessary to form and attach the two members, there is a problem in terms of the manufacturing cost of the members and the number of attachment steps.

  Furthermore, in the shoji closed state, the summoning jar is subjected to a force in a direction away from and approaching each other due to a difference in atmospheric pressure between the inside and outside of the room, and the smoke return that is alternately present is also separated and approached. Such a summoning unit is required to have high watertightness and airtightness when the shoji is closed. However, the conventional smoke return member is not provided with a watertight material or airtight material, or even if it is provided, its mounting position and shape are not good, so it is high due to deformation or dropping due to aging deterioration. There was a problem that watertightness and airtightness were not obtained, and that the watertight material or the airtight material gave resistance just before the shoji was completely closed, making it difficult to lock the crescent lock.

  The present invention has been made in view of the above points, and the problem to be solved is to reduce the manufacturing cost of the cover member that covers the concave portion of the end face of the summoning bowl and the smoke return member that is attached to the summing face. Another object of the present invention is to provide a synthetic resin sash capable of reducing the number of mounting steps and providing high water tightness and air tightness in a closed state without giving resistance immediately before the shoji is completely closed.

  In order to solve the above-described problems, the present invention provides a frame made of a rectangular frame made of an upper and lower frame and left and right vertical frames. And a synthetic resin sash in which the inner and outer shojis formed in a square shape are used in common with the left and right vertical saddles, and (a) a cover portion that covers the recess, A cover smoke return member integrally having a smoke return portion bent and extended from the cover portion to the summing surface side, and having an elastic fin integrally in the vicinity of a tip portion of the smoke return portion; It fits into the recess of the summoning bowl, and the smoke return part is fixedly attached to the summing surface of the summoning bowl with a screw (claim 1).

  The smoke-returning part of the cover smoke-reducing member is formed between the L-shaped linkage part formed on the front end side of the cover smoke-removing member and the linkage part and the cover part, and is fixed to the summoning tub with screws. The elastic fin includes a fixed portion, and the elastic fin extends obliquely in a direction away from the fixed portion toward the summing surface at an intermediate position of the side parallel to the summing surface of the summoning bowl. An elastic fin, and a second elastic fin provided in the fixing portion and projecting in the direction of the other summoning hook, and the first elastic fin is attached to the tip of the linkage portion of another cover smoke return member when the shoji is closed It is desirable that the second elastic fins are in contact with the summing surface of another summing bowl (claim 2).

  It is desirable that the fixing portion of the smoke return portion has a recess, and is fixed to the summoning tub by a screw screwed into the indoor extension portion or the outdoor extension portion that forms the recess of the summon candy from the recess. (Claim 3).

  According to the first aspect of the present invention, the cover smoke return member is formed by integrating the cover portion that covers the concave portion of the summoning bowl with one member and the smoke return portion that is bent and extended from the cover portion to the summing surface side. Therefore, the manufacturing cost is reduced as compared with the case of using separate cover members and smoke return members, and the number of man-hours for attaching to the summon bowl is also halved. Then, the fixing part is fitted into the recess, and the smoke return part is fixed to the summing surface of the summon bowl with screws, so that the attachment is easy and the anchor is firmly fixed to the summon bowl.

  According to the invention of claim 2, the smoke return part of the cover smoke return member is formed between the L-shaped linkage part formed on the front end side of the cover smoke return member, the linkage part and the cover part, The elastic fin extends obliquely in a direction away from the fixing portion toward the summing surface at an intermediate position of the side parallel to the summing surface of the linkage portion. Since the first elastic fin is provided, immediately before the shoji is completely closed, the tips of the linkage portions of the smoke return portions of the cover smoke return members of both summoning rods come into contact with the first elastic fins of the other summing rods. When fully closed, the tip of the linkage portion elastically contacts the first elastic fin. Therefore, the first fin does not give resistance to movement when the shoji is completely closed, and does not make it difficult to lock the crescent lock. In addition, very high water tightness is ensured when fully closed. In addition, the second elastic fins abut against the other summing rods on both sides of the summing unit, that is, inside and outside the watertight position by the first elastic fins, so that high airtightness is ensured.

  Furthermore, according to the invention of claim 3, since the fixing portion of the smoke return portion is fixed to the summoning tub by screws screwed toward the wall forming the recess of the summoning ridge in the concave portion, The bonding strength to the summoning bowl can be increased, and the screw is screwed into a position that avoids the metal reinforcing member inserted into the hollow part of the summoning bowl, compared with the case where the screw is screwed into the reinforcing member. Can be screwed in easily.

Next, embodiments of the present invention will be described with reference to the drawings. 1 is a longitudinal sectional view of a synthetic resin sash according to the present embodiment, FIG. 2 is a transverse sectional view thereof, FIG. 3 is a transverse sectional view of a summing portion immediately before the shoji is completely closed, and FIG. 4 is a summoning in a closed state. FIG.
1 and 2, the synthetic resin sashes shown in FIGS. 1 and 2 are formed in a rectangular shape by using a known technique with the synthetic resin upper frame 1, lower frame 2, and left and right vertical frames 3, 4 having the same cross-sectional shape. In the frame F attached to the opening of the building, which is joined and framed, the upper cage 5, the lower cage 6 and the left and right vertical rods 7 and 8 made of synthetic resin cage materials having the same cross-sectional shape. Are joined together in a square shape using a known technique, and the inner and outer shojis D1 and D2 formed by sandwiching the glass plate 9 are accommodated in a sliding manner, and are known outside the shoji D2 on the outdoor side. The screen door D3 is accommodated.

  The frame material commonly used for the upper frame 1, the lower frame 2 and the left and right vertical frames 3 and 4 of the frame F has the protrusions 9 and 10 at two positions separated in the prospective direction in the middle of the inner peripheral surface. The protrusions 11 are respectively provided at the indoor side end portions of the peripheral surface. In the upper frame 1, the protrusions 9 and 10 are used as upper rails that fit the upper arm of the shojis D1 and D2, in the lower frame 2, as lower rails that fit the lower arm of the shoji, and the left vertical frame. 3, as a steady rest fitted to the door-side downside of the external obstacle D <b> 2 when closed, and in the right vertical frame 4, as a steady rest fitted to the door-side side downside of the internal obstacle D <b> 1 when closed. Used.

  The saddle material commonly used for the upper and lower saddles 6 and 6 and the left and right vertical saddles 7 and 8 of the shoji D1 and D2 has a hollow portion 12 at the center in the direction of finding, and is expected on the outer peripheral side of the hollow portion. A recessed portion 15 is provided between the indoor-side extension portion 13 and the outdoor-side extension portion 14 formed on both sides in the direction, and is opened to the outer peripheral end surface. The formed outdoor side extension part 16 and the groove | channel 17 for fitting the pressing edge 18 in the prospective direction indoor side are provided. A pressing edge 18 is fitted into the groove 17 of each ridge, and a multilayer glass or other glass plate G is fixed between the pressing edge 18 and the outdoor extending portion 16.

  Similarly, in any of the shojis D1 and D2, the concave portion 15 of each saddle member is used for fitting the lower end portions of the rails 9 and 10 of the upper frame 1 in the upper collar 5, and the door roller in the lower collar 6. 19 is used for fitting and fitting the upper ends of the rails 9 and 10 of the lower frame 2. Of the vertical fences, the door-side vertical fence 7 has the vertical frame 7 closed when the shoji is closed. It is used to fit the steady rest 9 or 10 projecting from the opposing surface. On the other hand, in the summoning bowls 8 and 8E that are the vertical fences facing when both shoji screens are closed, the recess 15 has no use. If no measures are taken on the recess 15, the recess 15 not only opens over the entire length of the summoning rods 8, 8 </ b> E at the end faces of the summoning rods 8, 8 </ b> E, , 6 to the end of the recess 15.

  In the present invention, the summoning rods 8 and 8E cover the respective recesses 15 and are fitted with cover smoke return members 20 and 20E for ensuring high watertightness and airtightness at the summoning portion when the shoji is closed. It is. Both the cover smoke-removing members 20 and 20E are made of synthetic resin, are formed in a substantially L-shaped cross section, and have the same or substantially the same cross-sectional shape. A cover portion 21 provided at a portion corresponding to one side of the L shape and a smoke return portion 22 provided at a portion corresponding to the other side of the L shape are integrally provided.

  The cover portion 21 is for covering the concave portion 15 of the summon bowls 8 and 8E, and is fitted into a groove 15a formed on the inner side of the opening portion of the concave portion 15 of the saddle material at a spaced position on the back surface. A locking piece 21a is provided. Moreover, the smoke return part 22 is bent and extended from the cover part 21 to the summing surface side, and extends in both the indoor direction and the outdoor direction on both sides in the direction of finding, both of which are first made of soft synthetic resin. The elastic fins 23a and the second elastic fins 23b are provided by integral molding.

  More preferably, the smoke return portion 22 includes an L-shaped linkage portion 22a provided on the front end side of the cover smoke return members 20 and 20E, and a fixing portion 22b provided on the cover portion 21 side. Further, the fixed portion 22b is formed in an L shape whose cross-sectional shape is opposite to that of the linkage portion 22a, and has a recess 22c between the linkage portion 22a. And the cover smoke-returning member 20 of the inner impoverished child D1 abuts the locking piece 21a of the cover part 21 in the recess 15 and abuts the fixed part 22b of the smoke-returning part on the outdoor surface of the summoning bowl 8, The screw 24 is attached by screwing the screw 24 from the recess 22c into the outdoor extending portion 14 of the summon bowl 8. Further, the cover smoke return member 20E of the external shoji D2 engages the locking piece 21a of the cover portion 21 with the concave portion 15, and abuts the fixing portion 22b of the smoke return portion with the indoor surface of the summoning bowl 8E, It is attached by screwing the screw 24 from the recess 22c into the indoor extension portion 13 of the summoning bowl 8E.

  The first elastic fins 23a are inclined at the intermediate positions of the mutually opposing surfaces of the linking portions 22a of the cover smoke return members 20 and 20E of the summoning rods 8 and 8E, in the direction toward the tip of the other linking portions. It is provided. For this reason, when the shoji is closed, the linking portions 22a start to cooperate with each other immediately before the complete closing, and first, the tips of the linking portions abut against the other first elastic fins 23a. The fin 23a is moved to the fully closed position while being deformed, and in the fully closed state, as shown in FIG. 4, the tips of the linking parts abut against the first elastic fins. For this reason, high water-tightness is ensured by the double first elastic fins 23a in the linkage portions 22a that are linked in a staggered manner from the outdoor to the indoor direction or vice versa. At the same time, since the second elastic fins 23b of each summoning bowl come into contact with the other summoning bowls, high airtightness is secured between the two summoning bowls.

  When an airtight material such as an elastic round edge is fitted inside the linkage portion 22a instead of the elastic fin 23a, a relatively large resistance acts when the linkage portion collides with the airtight material when the shoji is completely closed. For this reason, the closing of the shoji is hindered, and it may be difficult to lock the crescent lock CR. However, in the present embodiment, the elastic fins 23a have flexibility, so that there is no such difficulty and smooth completeness. It can be closed to ensure watertightness and airtightness. Further, since the elastic fins 23a are formed integrally with the cover smoke return member, the elastic fins 23a will not fall off the cover smoke return member even if the shoji is repeatedly opened and closed.

  In each figure, 25 is a metal reinforcing material inserted in the hollow part of each cage. And in the summon baskets 8 and 8E, the cover smoke-removing materials 20 and 20E are fixed by screwing screws 24 into the indoor-side extension part 13 or the outdoor-side extension part 14 that form the recesses 15 of each bottle. As compared with the case where the screw 24 is screwed into the metal reinforcing member 25, the screw can be screwed easily. Moreover, since the cover part 21 is fitted in the recessed part 15 and the smoke return part 22 is fixed with screws, the cover smoke return materials 20 and 20E are easy to attach to the summon bowl and have a large mounting strength. If there is a large pressure difference between the inside and outside of the room at the time of closing, it is easy to apply force to the linked parts that are linked to each other, but they are firmly fixed by screws at positions close to the linked parts. Can withstand enough.
