Description

[Detailed explanation of the invention] This invention was developed for various aluminum sashes, entrance doors,
When equipping fittings such as partitions with insect screens, this article relates to a completely new installation structure for the mesh frame that uses original creativity at the joint between the sash frame and the screen frame. The screen frame is constructed so that it can be attached extremely quickly and easily with a one-touch operation, and it is also devised to prevent the screen frame from wobbling inside the sash frame after being attached.

Hereinafter, the present invention will be specifically explained with reference to drawings of embodiments. The drawings show an example of an implementation structure when this invention is applied to a mesh frame attachment part of a back door with a movable louver.

In the drawing, 1 is a sash frame attached to the main part of a door (not shown), 2 is a mesh frame attached to the indoor side of the sash frame 1, and a movable louver part 3 is provided inside the sash frame 1. A net body 4 is mounted inside the net frame 2, and the peripheral edge 4a of the net body 4 is pushed into each frame rib 2a of the net frame 2 from the back side with a net presser rope 5 and fixed.

This point is basically the same as the conventional sash of the same type, but in the case of the present invention, the indoor side surface of the sash frame 1 is formed with a tome-shaped cross section so as to surround the opening 1a in the frame. A recessed groove 6 for attaching the screen frame is provided, and mounting legs 7 projecting into the recessed groove 6 of the sash frame 1 are provided on the back side of the screen frame 2.

The groove edge of the concave groove 6 of the sash frame 1 and the tip of the mounting leg 7 of the screen frame 2 have projecting edges 6a that engage with each other when the screen frame is attached. a is provided, and the distance between the protruding edges 6a, 6a facing vertically and horizontally on the sash frame 1 side, and the distance between the mesh frame 2
The ridges that face each other vertically and horizontally? a,? The distance d between the mesh frame 1 and the mesh frame 1 is set so that the distance d between the mesh frame 1 and the mesh frame 2 is larger than the distance d between the mesh frame 2 and the protruding edges 7a, ? The end faces of a are each inclined wedge-shaped from the inside to the outside.

Since the present invention has the above-mentioned structure, when attaching the net frame 2 to the sash frame 1, the net frame 2 is supported so as to be parallel to the sash frame 1 as shown in FIG. Push forward as shown by the arrow, align the mounting legs 7 provided on each frame frame 2a of the screen frame 2 with the grooves 6 of the sash frame 1, and press the entire screen frame 2 strongly from the indoor side. The protruding edge 7a at the tip of the mounting leg 7 on the frame 2 side is connected to the concave groove 6 on the sash frame 1 side.
The projecting edges 6a and ? a is elastically engaged as shown in FIG. 1, and the mesh frame 2 is connected and fixed to prevent it from coming off from the sash frame 1.

Note that the mesh frame 2 can be attached from the outdoor side by providing a groove 6 on the outdoor side surface of the sash frame 1.

As described above, if the mesh frame mounting structure of the present invention is applied to various aluminum sash frames and fittings, the mesh frame can be mounted to these sash frames extremely quickly and easily with a one-touch operation. In the case of the mesh frame, each frame bone that supports the mesh body is expanded in the outer circumferential direction when the mesh frame is installed, so the mesh body is always maintained in a tensioned state, and of course, wrinkles and walnuts do not occur. This prevents the mesh frame from wobbling inside the sash frame and can be firmly fixed in an immovable state.
