Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a chimney safety guard that is attached to a stove chimney to prevent burns.

[Conventional technology]

Conventional safety guards have semicircular mesh guards that can be opened and closed, and these two semicircular guards are used to tighten and secure both sides of the chimney. Although it is installed, if the size of the chimney is slightly different or the outer circumferential surface of the chimney is deformed, it may not be securely tightened and may fall off during use.

[The problem that the idea attempts to solve]

The technical problem of the present invention is to provide a simple structure that solves these drawbacks and securely fastens the safety guard to the chimney.

[Means to solve the problem]

A cylindrical guard body in which 12 elongated semicircular gutter-shaped guards made of lath, perforated plate, expanded metal, etc. are butted against each other, one edge of the butts is hinged, and the other edge can be opened and closed. A cross-sectional rim 2 is provided on the upper and lower edges of the left and right semicircular gutter-like guards 1, respectively, and the left and right semicircular gutter-like guards 1 are fastened to the rims 2 to form a predetermined cylindrical shape. A clamping fitting 3 is provided to attach and fix the left and right opposing edges 2.
A bolt 8 is provided protruding inside the center of the lower piece, a coil spring 7 is fitted onto the bolt 8, the middle part of the arc-shaped spring plate 6 is fitted onto the tip of the bolt 8, and a nut 9 is screwed. A safety guard for a chimney, characterized in that a pressure member 5 is provided to press against the outer peripheral surface of a chimney 4.

[Effect]

With the semicircular gutter guard 1 open to the left and right, open the chimney 4.
When the semicircular gutter-shaped guard 1 is closed to its original state after the semicircular gutter-shaped guard 1 is fitted, the outer circumferential surface of the chimney 4 is pressed into contact with the pressing member 5, and when the semicircular gutter-shaped guard 1 is tightened with the clamping fitting 3, 2 The guard main body a formed by the semicircular gutter-shaped guards 1 is fixed to the outer peripheral surface of the chimney 4.

Therefore, the chimney 4 is safely guarded by the attached guard body a.

〔Example〕

The semicircular gutter-shaped guard 1 shown in the drawings is shown as a lath, with a molded rim 2 spot-welded to the upper and lower edges, and a pressure member 5 provided inside the center of the lower part of the rim 2.

In the elastic member 5 shown in FIG. 1, an arc-shaped spring plate 6 is provided inside the center of the lower part of the rim 2 with a gap therebetween, and a bolt 8 is inserted between the spring plate 6 and the rim 2 via a coil spring 7. , and FIG. 5 shows a case in which one end of the arc-shaped spring plate 6 is fixed to the inner side of the lower piece of the rim 2.

The fastening fitting 3 shown in the drawings is composed of a hook 10 on one side and a hook ring 11 on the other side.

12 in the figure is a hinge.

[Effect of idea]

Since the present invention uses a cross-sectional edge metal, both the fastening metal fitting 3 and the elastic member 5 can be easily attached to the lower piece of the edge metal.

Also, close the left and right semicircular gutter-shaped guards 1 and close the chimney 4.
Due to the spring action of both the spring plate 6 and the coil spring 7 of the elastic member 5 which has been tightened, the outer circumferential surface of the chimney 4 is strongly pressed against the outer peripheral surface of the chimney 4. The guard body a can be easily and reliably attached to the chimney 4 by tightening the guard body a through the chimney 4.

Therefore, to provide a safety guard for a chimney that can be reliably attached even if there is some gap between the chimney 4 and the rim 2, even if the chimney 4 is deformed, or even if the chimney size is a little small. It turns out.
