Description

[Detailed description of the invention] The present invention has a shoji stile and a sash with a structure that enables a so-called mime joint, in which the end faces of members cut at 45 degrees are joined to each other and assembled at right angles. Regarding Satsushi.

In conventional sashes, the frame and stile are fastened and joined by cutting at 45 degrees, but due to the locking structure of the sash, this cannot be done, so a so-called butt structure of cutting at 90 degrees was used. Therefore, the design features of the fastening type could not be fully demonstrated, and there were problems in that the aesthetics could not be satisfied.

The object of the present invention is to provide a fastening and joining sash that can fully exhibit the design features of the fastening and joining type by making the locking structure of the ribbed edge capable of fastening and joining.

Next, description will be given with reference to the drawings. The illustrated example relates to a rotating sash, but in the conventional sash, as shown in FIGS. 1 and 2, the frame 1 and the stile 10 of the shoji are fastened together, but the latch 20 has a locking structure. , since it was locked to the stile 10 from the inner circumferential side as shown by arrow A in Figure 2, if the end face is cut at a 45 degree angle, the two upper and lower or left and right ribs can be locked to the stile, but the remaining The two had the above-mentioned drawbacks because the ridges collided with each other at the end faces, making it difficult to lock them together. In the figure, 2 is glass and 3 is a backup material.

The structure of the sash according to the present invention, as shown in FIG. 3, makes it possible to fasten and connect the sill 20 as well, and therefore, as shown in FIG. A protruding piece 12 is provided, and a protruding piece 21 having the same cross-section and engaging with the protruding piece 12 is provided on the ridge. The protruding piece 12 on the stile side is open toward the outer circumference, that is, toward the frame, and the protruding piece 21 on the rim is therefore open toward the inner circumference. In order to prevent the ridge 20 from falling off, a single protruding piece 13 is provided on the stile or the ledge at the outer peripheral edge of the stile 10 in the embodiment shown in FIG. Protrusions 22, 23 are provided on the rim 20.

Preferably, a single protruding piece 24 is further provided approximately midway between the protruding piece 21 and the protrusion 22 of the rim, and the tip of the protruding piece 24 is adapted to abut against the outer wall surface 11 of the stile. In this case, the part between the protruding piece 21 and the protruding piece 24 of the ridge 20 has a thickness necessary for strength, but the part from the protruding piece 24 to the protrusion 22 has the friction property (plate spring property) necessary for the locking operation. ), the board thickness is made smaller than other parts. In addition,
This intermediate projecting piece 24 is provided on the frame 10 instead of being provided on the lug.
may be provided.

As shown in FIG. 4, when the edge 20 is attached to the frame 10, the protrusions 12 and 21 are engaged against wind pressure in the positive pressure direction (arrow B) or the negative pressure direction (arrow C). The protruding piece 24 plays a role of absorbing the moment about the engaging part as a fulcrum during negative pressure and when inserting the glass backup material 3 by coming into contact with the outer wall surface 11 of the stile. . The protruding piece 13 prevents the rim from falling off by engaging with the protrusions 22 and 23.

In the example shown in FIG. 4, a protrusion 24 is provided as a measure to improve strength performance and prevent rotation due to moment, but the anti-rotation effect is caused by the protrusion 13 and the protrusions 22, 2.
3, the protruding piece 24 can be omitted as shown in FIG. 8 if strength performance is considered.

Next, to explain how to attach the rim, first, as shown in FIG.
The ridge 20 is placed against the outer wall surface 11 of the stile so as to be located slightly on the outer periphery side, and then the ridge 20 is moved toward the inner periphery along the outer wall surface 11 as shown by arrow D in FIG. When the projection 21 begins to engage the projection 12, the projection 22 contacts the tip of the projection 13 and that portion of the ridge is bent outward, ie in the direction of arrow E. When the ridge 20 is further moved in the direction of arrow D, as shown in FIG. Then, the ridge 20 is locked to the stile 10.

In addition, in the above embodiment, the protrusion 13 for preventing falling off is
are provided on the stile 10, but as shown in FIG. 8, a similar protrusion 25 may be provided on the ledge 20, and protrusions 14, 15 for receiving the tips thereof may be provided on the stile.
Moreover, instead of providing the protrusion 24 for preventing rotation, as shown in FIG. 16, and the rib 20 may also be provided with a cross-sectional protrusion 26 that engages with the protrusion 16, and the engagement of these intermediate protrusions 16 and 26 makes the locking of the rib even stronger. It will be done. Furthermore, if desired, as shown in FIG. 10, the ridge 10 may be provided with a portion 27 serving as an outer covering on the outside of the protruding pieces 21 and 24, and a pair of protrusions 22 and 23 may be provided on the outer periphery of the rim 10. It becomes possible to create a design that takes full advantage of the features of fastening and joining.

Therefore, according to the present invention, the lug is locked to the stile by being moved from the outer circumferential side to the inner circumferential side of the stile, so even if both ends of each lug are cut at 45 degrees, All of the ridges can be easily attached and will not hit the ends of other ridges and become unlatched. Therefore, the crimped edge can also be fastened and joined, resulting in a fastening and joining sash that is desirable in terms of design.
