Abstract

PURPOSE:To increase safety by a method wherein a transparent body drop preventing member, controlling the movement of the transparent body along the extending surface thereof, is provided. CONSTITUTION:The transparent body drop preventing member 6, whose one end is retained and supported at the inner end of an end wall 1A at the upper opening of a box-type main frame 1 and the other end thereof is extending along the inner surface of a back retainer 4 along the end wall 1A, is provided. According to this method, the transparent body 2 is controlled by the surface of the member 6, which is facing to the outer peripheral surface of the transparent body 2, even when the retainer 4 is brought into an opened condition by the deformation thereof due to snow or the like, and the transparent body 2 will never be dropped by slipping.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solar heat collector, and more particularly to a structure for preventing a transparent body from falling, which is stretched over an open upper surface of a box-shaped body.

As this solar heat collector, as shown in Fig. 1, a transparent body 2 such as a transparent glass plate is stretched over the upper WJ opening of a box-shaped body 1, and the outer peripheral end of the transparent body is connected to the box-shaped body 1. It is clamped and fixed between the end wall 1A of the upper surface open part and a presser 4 which is fixed to the side wall of the main body 1 by fixing screws 3 and has a U-shaped cross section with one end wall, and a transparent material is mounted on the clamping and fixed surface. There is a structure in which a backing 5 fitted to the outer circumferential end of 2 is interposed.

This solar heat collector is installed at an angle on the roof of a building, etc., but when snow accumulates on the top surface of the box-shaped body 1, that is, on the surface of the transparent body 20, the weight of the snow causes the transparent body to 2 is bent, the contact surface between the presser 4 and the backing 5 opens, creating a gap, into which snow can enter.

When the snow melts, it slides down along the surface of the transparent body 20 in the direction in which the transparent body 2 is inclined, but if the snow that has penetrated into the gap freezes at night, it causes a wedge effect. As a result, the presser 4 may be raised and turned over as shown by the dotted line in the figure. As a result, the holding of the transparent body 2 becomes incomplete, and the transparent body 2 moves in the direction along the extending surface of the box-shaped main body 1.
In the end, it falls, which is extremely dangerous.

The present invention has been made in view of the above points, and includes movement in the direction along the stretched surface of the transparent body. The present invention aims to provide a solar heat collector that eliminates the conventional drawbacks and improves safety by providing a member to prevent the fall of the transparent body.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the present invention, a transparent body falling prevention member that faces the outer circumferential surface of the transparent body inside the presser of the transparent body and restricts the movement of the transparent body in the direction along the stretched surface is attached to the upper surface of the box-shaped body. It is characterized in that it is supported on the end wall of the open portion.

That is, in FIG. 1, reference numeral 6 denotes the above-mentioned transparent body falling prevention member, and in this embodiment, one end is latched and supported at the inner end of the end 111A of the open top portion of the box-shaped main body 1, and the other end is supported. It is formed in a shape that extends along the inner end surface of the rear presser 4 that extends along the end wall IA. Such a transparent body falling prevention member 6
#i They are especially provided at multiple positions on the inclined end side of the heat collector. If such a member 6 for preventing the transparent body from falling is provided, even if the presser 4 is deformed and opened as shown in FIG. Movement in the direction along the transparent body is regulated by the portion of the transparent body falling prevention member 6 facing the outer circumferential surface of the transparent body 2, eliminating the possibility that the transparent body 2 will shift and fall.

As described above, in the present invention, it is necessary to install a member that restricts the movement of the transparent body in the direction along the stretched surface, and to prevent the holding device of the transparent body from opening due to the influence of snow, etc. too,
There is an advantage that safety is ensured since there is no fear that the transparent body will shift and fall.

Claims (1)

[Claims] 111 A transparent body is stretched over the open top of the box-shaped body, and the outer peripheral end tube of the transparent body is fixed to the end wall of the open top of the box-shaped body and the box-shaped body. In a solar heat collector which is clamped and fixed to the end wall by a holding device having a square cross-section, a portion of the transparent body is placed on the extending surface of the transparent body opposite to the outer circumferential surface of the transparent body on the inside of the holding device. A solar heat collector characterized in that a transparent body fall prevention member for regulating movement in the direction along the box is supported on an end wall of an open top portion of the box-shaped main body. (2) The transparent body falling prevention member has one end locked and supported by the inner end of the end wall of the open upper surface of the box-shaped main body, and the other end supported along the inner end surface of the rear holding tool that extends along the end wall. The solar heat collector according to claim 1, which is formed in a shape that extends.
