Abstract

PROBLEM TO BE SOLVED: To easily install a cover on a sprinkler head, and to protect the sprinkler head from dust, dirt and soot/smoke by forming a collar having the adhesive parts on the upper surface on the upper edge of the bottomed cylindrical vessel-shaped cover, and forming plural notches in the bottom part and a side wall of the cover. SOLUTION: The adhesive parts 4 are arranged in plural places of the upper surface or the whole upper surface of this collar 2 by integrally forming the collar 2 along the edge of the upper opening part of a cover A by respectively forming plural notches 5 at proper intervals in a side wall 1 and the bottom part 3 of the bottomed cylindrical vessel-shaped cover A. Therefore, the cover A can be installed on the ceiling in a state of covering a sprinkler head only by allowing the cover A to abut in the adhesive parts 4 to the indoor ceiling surface. When water is blown out after a sprinkler is actuated when a fire breaks out, the cover A does not hinder blowout of water since the cover A tears from these notches 5 by water pressure.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sprinkler cover for preventing foreign matter, such as dust and soot, from adhering to a fire extinguishing sprinkler provided on an indoor ceiling of a building.

[0002]

2. Description of the Related Art Conventionally, as a dustproof cover of a sprinkler, a large number of cylindrical protective covers and decorative covers provided with a large number of holes around them are provided.

[0003]

However, these sprinkler covers have the following disadvantages. a. Only light dust and dust could be removed. b. It took a lot of trouble to remove the adhering substances that were vaporized (oil etc.). c. It took time to handle. An object of the present invention is to provide a sprinkler cover that can prevent dust, dust, soot and the like from adhering to the sprinkler by providing a cover so as to wrap the sprinkler, and that can easily be attached and detached and replaced. I do.

[0004]

According to the present invention, a flange 2 is provided on the upper edge of a cylindrical cover A having a bottom.
An adhesive portion 4 is provided on the upper surface of the flange, and a plurality of cuts 5 are provided on the bottom 3 and the side wall 1 of the cover A.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The actual use of the present invention constructed as described above is as follows. As shown in FIG. 3, the bonding portion 4 of the flange 2 is
To the ceiling 7. When the cover A is adhered in this way, intrusion of dust and dirt is completely prevented, and the sprinkler 6
There is no dust on the surface.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the present invention, and FIG.
FIG. 3 is a view showing an example of an attached state of the present invention, and reference numeral A in the figure indicates a cover. Reference numeral 1 denotes a side wall of a cover A in the form of a cylindrical container having a bottom. The side wall 1 is provided with cuts 5 at appropriate intervals. Reference numeral 2 denotes a flange provided along the edge of the upper opening of the cover A, and an adhesive portion 4 is provided at a plurality of locations on the upper surface of the flange 2 or on the entire upper surface. Adhesive part 4
The cover A is attached to the ceiling 7 only by contacting
Reference numeral 3 denotes a bottom of the cover A, and a plurality of necessary cuts 5 similar to the cuts 5 provided on the side wall 1 of the cover A are provided. Reference numeral 4 denotes an adhesive portion provided on the surface of the flange 2 of the cover A, which has an excellent adhesive property such as an adhesive or an adhesive tape. Reference numeral 5 denotes cuts provided in the side wall 1 and the bottom 3 of the cover A. When the sprinkler 6 connected to the water pipe h operates and water spouts out, the cover A is torn from the cuts 5 by water pressure, and the spout of water is hindered. It does not become. Notch A is not only made of a material which is easily broken or unraveled by heat such as a fire, but notch 5 is usually in a sealed state.
Dust and soot are prevented from entering. Also, various types of sprinklers 6 are provided, such as a flash type, a dry downward type, a fusible link type, a multi-type, and a glass bubble type. The cover A may be made according to each type.

[0007]

As described above, the present invention has the following advantages. a. Since the sprinkler is covered in a sealed manner, dust and soot do not enter at all. b. Since the handling is simple, the sprinkler can be replaced as needed. c. Applying colors and patterns to the cover increases the design value of the room.
