Description

  The present invention relates to a sash provided with a screen door.

  Patent Document 1 discloses a sash that has no screen door wrinkles. An attachment groove that opens toward the outdoor side or the indoor side is formed in the sash frame, and an attachment that locks the end of the net is attached from the outdoor side or the indoor side. The one fitted in the groove is described. This sash has a problem in design because the attachment can be seen in front view of the outdoor side or the indoor side.

  Patent Document 2 describes a sash frame in which an attachment groove is formed by opening on an inner periphery side, and an attachment that engages an end of a mesh is fitted into the attachment groove from the inner periphery side. The surface of the attachment is flush with the inner peripheral surface of the sash frame. In this sash, in order to remove the attachment for the maintenance of the net, it is necessary to forcefully pry a thin tool such as a flat-blade screwdriver into the mounting groove along the inside of the net, In some cases, the net or sash frame was damaged, or the net was torn. Also, the mounting groove may be deformed in an attempt to forcibly widen the mounting groove with a tool. Moreover, in order to remove the attachment, it is necessary to apply a force in the in-plane direction, but the force applied by the tool is perpendicular to the direction in which the groove is expanded (out-of-plane direction), and the groove is actually deformed. Otherwise, the force cannot be transmitted in the in-plane direction to the attachment, so the attachment is very difficult to remove, and the work of removing the attachment has become a troublesome work that accumulates stress for the operator.

As described above, this sash has a neat and open design because the sash frame 1, the shoji 2 and the screen door 3 are not visible when viewed from the front in the room.

  Next, the structure of each part will be described in more detail. As shown in FIGS. 1 and 4, the lower frame 4 has standing pieces 19 a and 19 b that protrude inward from the intermediate portion and the indoor side end in the indoor / outdoor direction. A concave groove 21 opened to the inner peripheral side with the prospective piece 20 is formed, and the concave groove 21 is closed by a resin cover material 22a. The indoor side end of the cover member 22 a is locked to the inner periphery of the frame 10. A tight material mounting groove 23 is formed in the upper part of the upright piece 19a in the middle of the indoor / outdoor direction toward the outdoor side, and the tight material 24 attached to the tight material mounting groove 23 closes the gap with the lower arm 12. It is out. A screen door engaging groove 18a opened to the inner peripheral side is formed on the upper chamber side of the upright piece 19a, and a screen door attachment 17a is engaged and attached to the screen door engaging groove 18a from the inner peripheral side. . Cover material locking grooves 25 are formed on the indoor side of the screen door engaging groove 18a and the upper end of the upright piece 19b at the indoor side end. As shown in FIGS. 4, 6, and 7, the cover member 22 a is formed of a hard resin and includes a plate-like portion 26 and locking claws 27 and 27 that protrude from the back surface (outer peripheral surface) of the plate-like portion 26. The claws 27 and 27 are fixedly attached to the cover material engaging grooves 25 and 25 of the lower frame 4, and the exposed portion on the indoor side from the screen door engaging groove 18 a of the lower frame 4 is covered by the plate-like portion 26.

A soft portion 28 is provided at the outdoor end of the plate-like portion 26, and as shown in FIGS. 6 and 7, the soft portion 28 closes the gap between the cover material 22a, the lower frame 4 and the attachment 17a.

  As shown in FIGS. 1 and 2, the upper frame 7 and the eaves frames 8 a and 8 b are also formed with a concave groove 21 that is open on the inner peripheral side, as in the case of the lower frame 4. Engagement grooves 18b, 18c and 18d are formed, and the screen door attachments 17b, 17c and 17d and the cover members 22b, 22c and 22d are adjacent to the indoor / outdoor direction to the upper frame 7 and the collar frames 8a and 8b, respectively. Engage and attach. Attachments 17b, 17c, and 17d and cover members 22b, 22c, and 22d have the same cross-sectional shape as those attached to the lower frame 4 (17a, 22a).

The operator device 5 includes a base member 29 and a lever handle 30 as shown in FIGS. The base member 29 is disposed through the cover member 22a and is fixed to the lower frame 4 with screws 31 from the inner peripheral side. The lever handle 30 is housed and disposed in a groove 32 formed on the upper surface of the base member 29, and when opening and closing, the lever handle 30 is raised obliquely as indicated by a virtual line in FIG. When the lever handle 30 is rotated, a drive pin (not shown) moves in the base member 29, and the movement of the lever handle 30 is transmitted to the opening / closing interlock device 6.
The opening / closing interlocking device 6 is disposed by being inserted through a notch 48 (see FIGS. 3 and 4) formed in the lower part of the upright piece 19a at the intermediate portion in the indoor / outdoor direction of the lower frame 4 and is erected by a screw 33 from the outdoor side. It is fixed to the piece 19a. Since the structure of the opening / closing interlock device 6 itself is not a feature of the present invention, a detailed description thereof is omitted. However, when the lever handle 30 of the operator device 5 is operated and the drive pin is operated, the movement is interlocked with the movement. The arm 34 connected to the lower arm 12 of the shoji 2 operates to open and close the shoji 2. The operator device 5 and the opening / closing interlocking device 6 have a structure that can be separated vertically.

  When the maintenance of the opening / closing interlocking device 6 is performed, as shown in FIG. 4, it is possible to remove the screw 31 and pull the operator device 5 upward, and remove the cover member 22 a of the lower frame 4. Since the attachment 17a of the screen door 3 is separated from the cover material 22a and engaged with the screen door engaging groove 18a of the lower frame 4, it is not necessary to remove the screen 16 or the attachment 17a to remove the cover material 22a. The maintenance of the opening / closing interlocking device 6 can be performed simply by removing only the cover material 22a.

The net 16 is provided with thick portions 35 over its entire length at the upper and lower ends of the longer length. The thick portion 35 uses one of fasteners used for clothing, bedding, etc., and the tape portion of the fastener is sewn or welded to the end of the net 16.
As shown in FIG. 5, the attachments 17 a, 17 b, 17 c, and 17 d include a horizontal plate portion 36, vertical plate portions 37 a, 37 b formed so as to protrude from the horizontal plate portion 36 to the outer peripheral side with a space in the indoor / outdoor direction. Thus, a groove 38 having a substantially U-shaped cross-section opening on the outer peripheral side is formed, the horizontal plate portion 36 is extended to the indoor side, and an extended piece 39 is formed. It has the protrusion 40 for the outer periphery which protrudes in this. On the outdoor side surface of the outdoor vertical plate portion 37a, a locking piece 42 that locks to the outdoor projection 41a in the screen door engaging grooves 18a, 18b, 18c, 18d protrudes in an inclined manner toward the inner peripheral side. A locking projection 43 is provided on the indoor side surface of the indoor vertical plate portion 37b to be engaged with the indoor projection 41b in the screen door engaging grooves 18a, 18b, 18c, 18d. . In the groove 38, locking portions 44 a and 44 b for locking the thick portions 35 provided at the upper and lower end portions of the mesh 16 are provided at two locations on the tip side and the back side of the groove 38. Each of the locking portions 44a and 44b is configured by protrusions 45a and 45b that protrude into the groove 38 from the outdoor and indoor vertical plate portions 37a and 37b, respectively. A space wider than the thick part 35 of the net 16 is formed in the groove 38. In the attachments 17a, 17b, 17c, and 17d, only the locking pieces 42 on the outdoor side are formed of a soft resin (in FIG. 5, the hatched portion indicates a portion formed of the soft resin), and the other portions are hard. It is made of resin. When the attachments 17a, 17b, 17c and 17d are attached to the screen door engaging grooves 18a, 18b, 18c and 18d of the sash frame 1, as shown in FIGS. Of the screen door engaging grooves 18a, 18b, 18c, 18d abuts against the tip of the indoor wall of the screen door engaging grooves 18a, 18b, 18c, 18d. The screen door engaging grooves 18a, 18b, 18c, and 18d are covered in a state of protruding to the side.

  As shown in FIGS. 3, 9, and 10, the attachment 17 d that is attached to the right frame 8 b as viewed from the indoor side is provided with a notch 47 in the outer circumferential protrusion 40 at the lower end.

  The procedure when the net 16 is stretched will be described. As shown in FIG. 5B, the thick portions 35 formed at the upper and lower ends of the net 16 are passed through the grooves 38 from the small openings of the attachments 17a and 17b. Then, the thick portion 35 is locked to the locking portion 44a on the distal end side in the groove 38. Then, when the upper and lower attachments 17a and 17b are attached to the mesh 16, as shown in FIG. 6A, the ends of the mesh 16 are folded back 180 ° so that the openings of the attachments 17a and 17b are engaged with the mesh door of the sash frame 1. The attachments 17a and 17b are pushed into the screen door engaging grooves 18a and 18b from the inner peripheral side so as to face the openings of the grooves 18a and 18b. As shown in FIG. 8A, the side edges of the mesh 16 are inserted into the mesh door engaging grooves 18c and 18d of the eaves frames 8a and 8b, and then the attachments 17c and 17d are attached to the eaves frame 8a and 8d from the inner peripheral side. The screen door engagement grooves 18c and 18d of 8b are pushed in and attached, and the screen door engagement grooves 18c and 18d and the attachments 17c and 17d hold the side edges of the screen 16 therebetween.

  In this way, the upper and lower ends of the mesh 16 are folded back 180 °, and the attachments 17a and 17b are directed toward the outer peripheral side so that the openings of the grooves 38 face the openings of the mesh door engaging grooves 18a and 18b of the sash frame 1. Since the 17a and 17b are engaged and attached to the screen door engaging grooves 18a and 18b from the inner peripheral side, no force acts in the direction of expanding the grooves 38 of the attachments 17a and 17b due to the tension of the net 16, so The portion 35 does not come off from the locking portions 44a of the attachments 17a and 17b, and the net 16 can be sufficiently tensioned. Moreover, since the screen door engaging grooves 18a and 18b are formed in the metal sash frame 1, the attachments 17a and 17b can be reliably engaged without being detached from the screen door engaging grooves 18a and 18b. Since most of the attachments 17a, 17b, 17c, and 17d are accommodated in the screen door engaging grooves 18a, 18b, 18c, and 18d, the design of the sash is impeded by the attachments 17a, 17b, 17c, and 17d and the view is limited. It can be prevented from being damaged. Furthermore, since the engagement pieces 42 on the outdoor side of the attachments 17a, 17b, 17c, 17d are formed in a fin shape with a soft resin, the attachments 17a, 17b, 17c, 17d are formed in the screen door engaging grooves 18a, 18b, 18c, 18d. It is possible to prevent the net 16 from being rubbed and damaged when pushed.

When the tension of the net 16 becomes weak due to aging, the four attachments 17a, 17b, 17c, and 17d can be removed once and the net 16 can be re-stretched so that the tension becomes strong. The procedure at this time will be described below.
First, a pointed tool such as a flat-blade screwdriver is inserted into a notch 47 formed in the lower part of the outer peripheral protruding piece 40 of the right attachment 17d that does not lock the end of the mesh 16, and the tip of the tool is inserted. The attachment 17d can be easily removed from the screen door engaging groove 18d by moving it to the inner peripheral side. When the right attachment 17d is removed, the right end surfaces of the upper and lower attachments 17a and 17b are exposed. By applying a force to the inner periphery by hooking a finger or a tool there, the upper and lower attachments 17a and 17b can be easily attached. Can be removed. Further, since the upper and lower attachments 17a and 17b lock the ends of the net 16, the net 16 can be removed by pulling. The left attachment 17c can be easily removed by hooking a finger or a tool on one of the upper and lower end faces and applying a force to the inner peripheral side.
When all the attachments 17a, 17b, 17c, 17d are removed, either one of the upper and lower attachments 17a, 17b is once pulled out to the side, and the thick wall at the end of the mesh 16 is shown in FIG. 5 (c). The portion 35 is inserted into the groove 38 from the attachment mouth, and the thick portion 35 of the net 16 is locked to the locking portion 44 b on the back side of the groove 38. Thereafter, in the same manner as when the net is first stretched, the upper and lower attachments 17a and 17b are engaged with the screen door engaging grooves 18a and 18b of the upper and lower frames so that the upper and lower ends of the net 16 are folded back as shown in FIG. After that, as shown in FIG. 8, the left and right attachments 17c and 17d are engaged and attached to the screen door engaging grooves 18c and 18d of the frame frame to hold the side edges of the screen 16.
Further, when the tension of the net 16 becomes weaker as time passes, the attachment 17a, 17b, 17c, 17d is removed from the sash frame 1 again, and the attachment of the upper and lower attachments 17a, 17b that has been left as it is last is side by side. As shown in FIG. 5 (c), the thick portion 35 of the mesh 16 is locked to the locking portion 44b on the deep side of the groove, and each attachment 17a, 17b, 17c, 17d is locked to the screen door of the sash frame 1. The engaging grooves 18a, 18b, 18c and 18d are engaged and attached. That is, the sash can adjust the tension of the net 16 in three stages.

As described above, this sash is provided with the extension piece 39 and the outer peripheral protruding piece 40 extending to the indoor side on the attachments 17a, 17b, 17c, and 17d of the screen door 3, and these portions are engaged with the screen door of the sash frame 1. Since the notch 47 is provided in the outer circumferential protruding piece 40 at the longitudinal end of the attachment 17d that is protruded from the grooves 18a, 18b, 18c, and 18d and is first removed, the tool is slightly inserted into the notch 47. The attachment 17d can be easily removed by force, and the other attachments 17a, 17b, and 17c can be easily removed by hooking a finger or the like on the end surface, so that the net 16 can be easily maintained. Thus, by providing the notch 47 for tool insertion in the outer peripheral protrusion 40, there is no fear that the sash frame 1 or the net 16 will be damaged by the tool. The notch 47 is not visible from the inner peripheral side of the sash, and is hardly conspicuous in a front view from the indoor side (see FIG. 3). The design is not impaired, and by providing the notch 47, the attachment 17d is attached to the mesh 16. It is not easy to come off with tension.
Further, even when the attachments 17a, 17b, 17c, and 17d are removed for the maintenance of the mesh 16, as shown in FIGS. 6 (a) and 7 (a), the mesh door engaging grooves 18a and 18b of the sash frame 1 are used. , 18c, 18d, the indoor side is covered with the cover materials 22a, 22b, 22c, 22d, so that wind and rain can enter the room through the notch 48 formed in the lower frame 4 in order to install the opening / closing interlocking device 6. Since there is no blowing, maintenance of the net 16 can be performed at any time without being influenced by the weather.
Further, since the attachments 17a, 17b, 17c, and 17d are provided with a plurality of engaging portions 44a and 44b at the end of the mesh 16 in the depth direction of the groove 38, when the tension of the mesh 16 is weakened over time, the mesh 16 can be re-stretched so that the tension is increased, and the net 16 can be used for a long time in an appropriate state. When changing the locking position of the net 16 end, the attachments 17a and 17b are once pulled out, and the thick part 35 at the net 16 end is sequentially locked to the locking part 44b from the small edge of the attachment 17a and 17b. Thus, the locking position can be easily changed by anyone without using a tool. In the attachments 17a and 17b, the tension of the mesh 16 does not work in the direction of expanding the groove 38 of the attachment, and the tension of the mesh 16 does not increase the width of the groove 38. The locking strength at the end of the mesh 16 does not change between when locked and when locked to the locking portion 44b on the back side.
By using a fastener as the thick portion 35 for locking the net 16, the thick portion 35 can be formed easily and at low cost, and the locking portions 44a and 44b of the attachment are formed by the rigid elements of the fastener. Can be securely locked.

  In addition, the sash covers the screen door engaging grooves 18a, 18b, 18c, 18d of the sash frame 1 with resin attachments 17a, 17b, 17c, 17d, and the screen door engaging grooves 18a, 18b of the sash frame 1. , 18c and 18d, the exposed portion on the indoor side is covered with resin cover materials 22a, 22b, 22c and 22d, so that the occurrence of condensation can be prevented. Also, the attachments 17a, 17b, 17c, and 17d are made of the same color black as the shoji tight material 24, for example, and the interior color can be changed simply by changing the resin cover materials 22a, 22b, 22c, and 22d. Can be changed. By changing the color tone of the attachments 17a, 17b, 17c, and 17d and the cover materials 22a, 22b, 22c, and 22d, the interior can be made a colorful two-tone design.

  11 and 12 show another embodiment of the sash of the present invention. In this sash, the cover members 22a, 22b, 22c, and 22d to be attached to the sash frame 1 are made of aluminum. Other parts are the same as those of the above-described embodiment.

  The present invention is not limited to the embodiments described above. The opening method of the shoji 2 is arbitrary. For example, the sliding door 2 may be opened in an overturning manner, may be rotated around the vertical axis, may be opened in a swinging manner, or may be opened in parallel. In the embodiment, the notch portion 47 for tool insertion is formed only at the lower end portion of the right attachment 17d when viewed from the indoor side, but the notch portion 47 is provided at the longitudinal end portions of the upper and lower attachments 17a and 17b. The notches 47 may be provided at the longitudinal ends of all the attachments 17a, 17b, 17c, 17d. In the embodiment, all four attachments have the same cross-sectional shape, but the attachments 17c and 17d that do not lock the end of the mesh 16 do not have the locking portions 44a and 44b of the mesh end. You can also. Further, the attachments 17c and 17d that are not locked by the ends of the mesh 16 and the screen door engaging grooves 18c and 18d for attaching the attachments 17c and 17d can be omitted. Also, the top, bottom, left, and right ends of the net 16 can be locked to the locking portions 44a or 44b of the attachments 17a, 17b, 17c, and 17d. The net 16 can also be provided with thick portions 35 for locking at the left and right edges. The extension piece 39 of the attachment is not necessarily horizontally extended to the indoor side, and may be inclined. The shape and size of the notch 47 can be changed as appropriate.
