Description

[Detailed Description of the Invention] This invention relates to a window frame that is attached to the indoor side of a window frame.

Examples of conventional picture frames of this type include those shown in FIGS. 1 and 2. This picture frame 1 is made of wood and is attached to a window frame 2, that is, an aluminum sash 2 frame with screws. Note that 3 is a concrete body and 4 is a glass door.

However, since all of the conventional picture frames 1 have corners 1a in cross section, there is a risk of unexpected injury if the frame 1 is bumped into. Particularly, in buildings such as school buildings where a large number of schoolchildren and students gather, there have been many accidents where students hit their heads on the corner 1a and sustain injuries.

This invention was made to solve these conventional problems, and its purpose is to fix the vertical and horizontal edges of a U-shaped cross section that is attached to the window frame, and the abutment area between these edges. To provide a window frame comprising a corner edge having a U-shaped cross section with rounded corners and attached over the window.

This invention will be explained below based on the embodiments shown in FIGS. 3 to 5.

First, to explain the structure, the picture frame F of this invention is
A vertical edge 6 made of resin and having a U-shaped cross section and attached to a vertical support frame 5a fixed to the indoor side of the window frame S with screws b.
and the horizontal support frame 5b fixed to the upper and lower parts of the window frame S on the indoor side.
U-shaped cross-section lateral edge 7.7 attached with screw b to
and the vertical edge 6 and the horizontal edge 7 at the corner of the window frame.
Corner 8a that is attached from above to the butt part of
and a corner edge 8 having a round U-shaped cross section, and the vertical edge 6 is attached to the corner edge 8 when the corner edge 8 is attached.
and a hook portion 9 that is hooked to the edge portions 6a, 7a of the side edge 7.
It is distinctive in that it is formed.

The vertical support frame 6 and the horizontal support frame 7 are a kind of adapter for attaching the picture frame F of this invention to the window frame S, and are attached to the window frame S with screws b. Therefore, both receiving frames 5a and 5b are formed to match the size of the picture frame F, and in the above embodiment,
It has a groove m into which the inner edges 6b and 7b of the vertical edge 6 and the horizontal edge 7 are inserted, and an edge e into which the outer bifurcated edges 6c and 7c are inserted.

In addition, 7 is an uneven surface for anti-slip formed on the side edge 7, 10 is a concrete body, 11 is a glass door,
12 is a sealing material. Moreover, the picture frame F may be made of aluminum casting.

Next, the action will be explained.

First, the vertical edge 6 and the horizontal edge 7 are attached to the vertical support frame 5a and the horizontal support frame 5b, which have been attached in advance to the indoor side of the window frame S, respectively. At that time, the inner edges 6b, 7b of both 6, 7 are inserted into the grooves m of the vertical support frame 5a and the horizontal support frame 5b, and the outer bifurcated edges 6c, 7c are similarly inserted into the ends of the above-mentioned both support frames 5a, 5b. Insert into edge e and screw b
Fix each.

Next, the corner edge 8 is placed over the abutted portion of the fixed vertical edge 6 and the horizontal edge 7, and the hook portion 9 is hooked onto the edge portions 6a, 7a of the vertical edge 6 and the horizontal edge 7.

After that, a sealing material 12 is filled into the joint between the concrete body 10 and the concrete body 10.

As explained above, in the picture frame of this invention, the vertical edge, the horizontal edge, and the corner edge that covers the abutting portion of both edges are formed into a U-shape in cross section, and the corners of the corner edge are formed into rounded shapes. Now that you have configured this, when you attach it to the window frame, the sharp corners will not appear on the indoor side.
In other words, a picture frame with rounded corners can be formed.

Therefore, according to the present invention, it is possible to effectively prevent injuries that are often caused by hitting conventional picture frames.
