JPS5817910Y2 - Window airtightness and glass retention devices - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a window airtightness and glass holding device whose purpose is to maintain airtightness between a window frame and a stile and to hold the glass.

Conventionally, the airtight material and the glass retaining material are each used separately to achieve their original purpose.

Therefore, there were problems such as high materials and material costs and troublesome construction.

This invention was made with the intention of solving the above problem, and by providing a device in which the airtight material and the glass holding material are integrally formed, it aims to reduce the materials and material costs, and The purpose is to significantly reduce the effort required during assembly.

Next, an embodiment of this invention will be described with reference to the drawings.

FIG. 1 is a schematic front view of the case where the bead 1 is installed on an inward-folding window, where 2 is a window frame, 3 is a shoji stile, and 4 is a
is a glass body held in the shoji stile 3, and 5, 5 is a hinge installed between the lower stile 2a of the window frame 2 and the lower stile 3a of the shoji stile 3; The shoji can be opened and closed.

A flange portion 2' protrudes from the outside surface of the window frame 2 in the thickness direction, with which the stile contacts and has a length that covers the stile 3. The side surface is provided with a step groove 3' for attaching the glass, and a channel-shaped groove 3'' extending from the step groove 3' toward the edge of the stile 3.

The bead 1 includes a three-pronged window frame contacting part 1a that is abutted against the flange part 2' of the window frame 2, and a two-pronged glass holding part 1b provided on the side opposite to this window frame contacting part 1a. , extending from one end of this glass holding part 1b,
The stile insertion part 1C is inserted into the channel-shaped groove 3'', and its installation is carried out by fitting the glass body 4 into the step groove 3'. The stile insertion part 1C is inserted into the channel-shaped groove 3'', and the glass holding part 1b is placed against the outer surface of the glass body 4.

The bead 1, which is attached to the outer surface of the shoji stile 3 as described above, works with the shoji stile 3 to securely hold the glass body 4 and prevent rainwater from entering. In addition, when the shoji is closed, the window frame contacting part 1a abuts against the flange part 2' of the window frame 2 in an air-water tight manner, preventing air from entering and exiting and preventing rainwater from entering. be able to.

The reason is that when the shoji is opened, the glass holding part 1b
Due to the forked shape of the glass body 4,
However, when the shoji is closed, the positive pressure applied to the shoji surface is received by the stile 3, and the negative pressure is received by the glass holding part 1b. This is because it is possible to completely prevent rainwater and the like from entering due to positive and negative pressure.

Thus, according to the window airtightness and glass holding device of this invention, one bead can serve both to maintain the airtightness between the window frame and the stile and to hold the glass, thereby reducing materials and material costs. In addition to this, it is possible to significantly reduce the amount of effort required during assembly.

In addition, in the above embodiment, a case where a bead is equipped on a window that folds inward is explained, but the bead can be used not only on a window that folds inward but also on a window that opens and closes like a revolving window or a casement window. In these cases, the contact area between the inwardly projecting flange of the window frame and the shoji stile is on the side, or on both the top and bottom sides, and the effects are as described above. Since it is the same as that for an inverted window, illustration and explanation will be omitted.
