Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for a window opening / closing gas spring, and more particularly to a mounting device for a window opening / closing gas spring used in a window opening / closing device.

[0002]

2. Description of the Related Art In a window opening / closing device, a window normally installed above a wall surface and a handle box installed below the wall surface are connected by a wire through a pulley, and the wire is wound by a winding operation of the handle box. Or it is released and the window is opened and closed. FIG. 13 shows an example of construction of such a window opening / closing device. In such a window opening / closing device 60, a gas spring 66 in which a piston rod is extendably attached to a cylinder is usually used as a biasing means for opening / closing the window.

Conventionally, this type of gas spring has its both ends connected to a window frame 61 and a window body 62 via brackets 67. FIG. 14 shows a structure of a gas spring mounting device used in a conventional window opening / closing device. As shown in FIG. 14, in the conventional mounting device, the bracket 67 has a mounting seat 6 fixed to a window frame or a window body.
8 and a male connector 69 such as a bolt is fixed to the mounting seat by caulking or the like. Then, the gas spring 66 and the bracket 67 are tightened with a female connecting tool 70 such as a nut after the male connecting portion 69 of the bracket is passed through the mounting hole 72 formed in the mounting piece 71 at the end of the gas spring. Connected.

[0004]

However, when a bracket for attaching the end portion of the gas spring by tightening the male type connector such as a bolt and the female type connector such as a nut is used, it is troublesome and time-consuming to perform the mounting work at a construction site. It takes. Especially when constructing a continuous window opening / closing device in which multiple windows are connected to each other, the continuous window opening / closing device is usually installed above the wall surface.Therefore, it must be carried while supporting a heavy iron window frame containing glass. However, the installation work required more time and labor, and there was a problem in terms of construction safety. In addition, since a large force of several tens of kilograms acts on the mounting portion of the gas spring for opening and closing the window, there is a serious drawback in that the screws are loosened during use when the screws are fixed by the bolts and nuts. In addition, in the conventional mounting device, since a male connector such as a bolt is integrally formed on the mounting seat by caulking or the like, there is a problem that the manufacturing cost is high and mass productivity is difficult.

The object of the present invention has been made in view of the above circumstances, and the mounting work of a gas spring used for opening and closing a window can be carried out simply and quickly, and the mounting portion does not become loose during use, and it can be used for a long period of time. (EN) Provided is a mounting device which can obtain a stable operation over a period of time, has a low manufacturing cost, and is suitable for mass production.
