Description

[Detailed Description of the Invention] This invention relates to a synthetic resin type sash member in which screw receiving portions are embedded so that the frame can be constructed with high strength.

As is well known, when sash members such as horizontal frames and vertical frames are molded from hard synthetic resin and screws are used to connect the horizontal and vertical frames, the fastening strength of the screws is significantly lower with hard synthetic resin than with metal. Therefore, the shoji frame does not have the strength.

Therefore, during use, the sash gradually becomes distorted and the connection between the horizontal frame and the vertical frame becomes disconnected, which is one reason why hard synthetic resin sashes are not put into practical use.

Therefore, the present invention constructs a frame with extremely high assembly strength by embedding metal screw receivers and driving the screws into the screw receivers when assembling the frame.

The present invention will be described below with reference to the illustrated embodiment. The synthetic resin type sash member a of the present invention is applied to the upper and lower horizontal frames 1, 1' of a sliding sliding door.

As is well known, a shoji screen is made of a square frame with upper and lower horizontal frames 1 and 1' and left and right vertical frames 2 and 2, and inside the frame there are glass plates,
It is made by fitting panels C made of synthetic resin or the like, and since the shoji screen shown in the drawings is vertical, the sash member a of the present invention is used for the upper and lower horizontal frames 1 and 1'.

Therefore, if the shoji is horizontal, the sash member of the present invention can be used for the left and right vertical frames, and the sash member of the present invention may be used for the window frame for fitting.

The upper and lower horizontal frames 1 and 1' are hollow frame-like long members with one or more intermediate pieces 4 provided between two opposing surface materials 3 and 3, and are arranged in the longitudinal direction. A pocket portion 5 is formed that is open along one side.

In the embodiment shown in the drawings, the upper horizontal frame 1 has one intermediate piece 4, the lower horizontal frame 1' has two intermediate pieces 4 vertically, and each intermediate piece 4 has a cylindrical protrusion 6. A metal screw receiving portion 7 is embedded in the protruding portion 6.

The screw receiving portion 7 shown in FIG. 3 has a cylindrical shape and has wing pieces 8, 8 on its outer surface, and the wing pieces 8, 8 serve to prevent rotation within the protrusion 6.

However, as shown in FIG. 4 or FIG. 5, the protrusion 6 is made into a rectangular tube shape, and the screw receiving portion 7 buried within the protrusion portion 6 is made into a rectangular tube shape, or a part thereof is lengthened. It may also have a rectangular tube shape with a notch 9 along the direction.

In any of the embodiments described above, it is preferable that the metal screw receiving portion 7 is provided along the entire length of the cross members 1, 1'.

By providing the screw receiving portion 7 over the entire length, the strength in the longitudinal direction of the member can be increased, and bending and warping are less likely to occur.

However, it may be provided only at both ends of each horizontal frame.

Further, the screw receiving portions 7 may be provided by being extruded integrally during the joint resin extrusion molding of the horizontal frame, but they may also be embedded by being driven into the end portions after the horizontal frame is molded.

To assemble a shoji screen using the upper and lower horizontal frames and left and right vertical frames 2, 2 made of synthetic resin as described above, wrap beads d around the four sides of panel C, and insert them into the ends of vertical frame 2. Fit the end of the horizontal frame so that the tip collides with the intermediate piece 2' of the vertical frame 2, and insert the screw 10 driven from the outside of the intermediate piece 2' into the screw receiver 7.
Tighten while cutting screws inside the panel C.
Fit it into the pocket part of the frame body, and firmly tighten all the connecting parts between the vertical frame and the horizontal frame with screws.

Therefore, all of the screws 10 driven from the outside of the vertical frame are fastened to the metal screw receivers 7, so that it is possible to provide a synthetic resin shoji that is as strong as a metal shoji.

The above explanation is for the case where screw receivers are provided on the upper and lower horizontal frames because the shoji runs vertically, but as mentioned above, if the shoji runs horizontally, the screw receivers can be provided on the vertical frames. .

Moreover, it can be applied not only to shoji screens but also to window frames for fitting and other frames.

In summary, according to the present invention, a cylindrical metal screw receiving part is buried in a cylindrical protrusion provided in an intermediate piece between opposing surface materials, and a screw driven from the outside of the connecting member is tightened. Therefore, the strength of the connected member is as strong as that of a metal member, and the assembled shoji frame or the like will not be distorted, or the connected portion will not come off or loosen.

Therefore, like metal sashes, they can withstand long-term use, and synthetic resin sashes can be put to practical use.

In addition, when manufacturing, it is possible to extrude synthetic resin together with a cylindrical screw receiving part, or to extrude synthetic resin in advance and then hammer in the screw receiving part, which greatly simplifies manufacturing and allows for products with high practical value. can be provided.
