DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window frame of a bathroom unit or the like constituting an indoor space.

[0002] As a window frame of a conventional bathroom unit, for example, in Japanese Utility Model Laid-Open Publication No. 61-201480, the position of the ridge is provided on a frame member made of a synthetic resin having a plurality of ridges formed on an outer surface thereof in a longitudinal direction. A tapping hole is provided over the entire length, and a through hole penetrating through the inner and outer surfaces of the frame material at one end of the frame material at the position of the ridge is formed. Assemble in a square frame shape in a swastika shape, contact the end of the frame material on the side with the through hole with the end surface of the other frame material, and tap the screw inserted through the through hole into the frame material to tap the other frame material A window frame of a bathroom unit screwed into the hole is described.

Since the tapping holes of the above frame material are small circular holes, it has been difficult to produce a long frame material with high dimensional accuracy by extrusion molding. In addition, the weight was heavy.

In Japanese Utility Model Laid-Open Publication No. 1-171888, a protruding ridge extending in the longitudinal direction is formed on the surface of a plate-shaped frame member. Formed along the pilot hole on the end face of the ridge,
Further, there is described a window frame of a bathroom unit in which a slit having a depth reaching a prepared hole is provided, and four plate-shaped frame members are combined to form four upper, lower, left and right frames.

In this case, the above-mentioned Japanese Utility Model Application Laid-Open No.
The problems of the window frame in Japanese Patent Publication No. 0, such as dimensional accuracy at the time of manufacturing and weight, can be solved. However, conversely, as shown in FIG. 8, the combination of the four frame members (33 to 36) constituting the window frame is performed in a vertical manner, so that the flange portion 38 having a substantially C-shaped cross section of the frame member. In order to cut both end faces at 45 degrees and apply a decorative fastening process, the following special cutting process must be performed.

That is, as shown in FIGS. 9 and 10,
For example, the end of one of the frame members 34 on the side of the frame member 35 is cut such that the main body end surface 51 is located forward of the flange end surface 53 inclined with respect to the end surface 51 in the longitudinal direction. Must be cut such that the main body end face 55 is located rearward in the longitudinal direction from the flange end face 57 inclined with respect to this end face 55. For this reason, the window frame 31
If it is necessary to change the size of the frame member, the end portion of the frame member has to be subjected to the same special cutting process again as described above, which is problematic.

In view of the above problems, the present inventor has studied a long frame material having a cross-sectional shape in which, for example, rectangular large and small hollow portions are formed in a line in a plate material. did. Specifically, the front and back surfaces are made almost flat, and the hollow portion in the plate body is partitioned by linear reinforcing ribs so that large and small hollow portions of a horizontally long rectangle and a square are formed. A ridge having a vertically long rectangular cross section protrudes inward. The small hollow portion is a screw hole.

[0008]

As described above, weight reduction can be achieved by making the frame member have a hollow structure.
And, by combining four plate-shaped frame members in a swastika shape,
Even if it is necessary to change the size of the window frame, it is not necessary to perform a special cutting process on the end of the frame member, but it is assembled in a square frame shape in a swastika shape with the above hollow type frame material. In the case of a window frame that has been fixed, when fixing it to the aluminum window sash with screws,
The presence of the large hollow portion inside the frame material that contacts the window sash may cause the following problems.

That is, even if the screws are screwed in and fixed to each other, the screw portion of the screw is screwed into the frame material only on the front and back surfaces of the plate material, and the pull-out strength (load) of the screw is low. It was weak at about 40kg. For this reason, as shown in FIG. 11, for example, when there is a gap between the window frame 1 and the window sill 8 in which the window sash 7 is fitted and fixed, for example, put a hand on the window frame 1 for cleaning. If you hang it, screw 2a
There was a problem that came off.

An object of the present invention is to provide a window frame which can be firmly fixed to a window sash without removing a screw even when there is a gap between the window frame and the window frame.

Another object of the present invention is to easily change the size of a window frame at a construction site without using a special cutting process at the end of the frame member, since the frame material is lightweight. It is possible to provide a window picture frame.

[0012]

According to the first aspect of the present invention, a window frame of the present invention is formed by combining four synthetic resin plate-like frame members having a plurality of hollow portions in a swastika shape to form four upper, lower, left and right surfaces. In the window frame whose front end is fixed to the window sash, a hollow portion does not exist in a portion of the plate-shaped frame member that comes into contact with the window sash.

According to a second aspect of the present invention, there is provided a window frame formed by combining four synthetic resin plate-like frame members having a plurality of hollow portions in a swastika shape to form four upper, lower, left, and right surfaces. In the window frame fixed to the window sash, a spacer member is inserted into a hollow portion of the plate-shaped frame member in contact with the window sash.

According to a third aspect of the present invention, there is provided the window frame according to the second aspect, wherein the spacer member is made of a synthetic resin.

(Operation) In the first aspect of the present invention, since there is no hollow portion in the portion of the plate-shaped frame member that comes into contact with the window sash, it is the same as the conventional solid-shaped plate-shaped frame member. A level of pull-out strength can be obtained.

Further, since the plate-shaped frame member has a hollow structure having a plurality of hollow portions, the window frame becomes light. Further, since the four plate-shaped frame members are combined in a swastika shape, the size of the window frame can be changed by simply cutting one end of the plate-shaped frame member.

According to the second aspect of the present invention, since the spacer member is inserted into the hollow portion of the plate-shaped frame member in contact with the window sash, the same level as that of the conventional solid-structured plate-shaped frame member is used. Pulling strength can be obtained.

According to the third aspect of the present invention, since the spacer member is made of synthetic resin, a plate-shaped frame member having a partially solid structure can be formed, for example, through an adhesive.
