[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fire wall device for protecting a hanging cabinet installed above a sink in a kitchen from an accidental fire due to overheating of a gas stove or the like.

[0002]

[Prior art]

 Conventionally, a hanging cabinet installed above the sink has a peripheral wall surrounded by a decorative plywood, and a box body provided with a door that can be opened and closed at the front opening is mounted in a hanging shape by a mounting bracket.

[0003]

[Problems to be solved by the device]

 By the way, the surrounding walls and doors of conventional hanging cabinets are made of plywood and other materials that are highly flame-retardant and self-extinguishing.The outer surface of the box body is coated with resin paint above the sink and above the gas stove. It is installed and used in. For items installed near the gas stove, the radiant heat and steam generated from the gas stove during cooking etc. significantly deteriorate the adhesive and the paint applied to the surface of the plywood, and the There is a danger of an unexpected fire. Therefore, it is intended to provide a fire wall device capable of protecting the hanging cabinet from the accidental fire.

[0004]

[Means for Solving the Problems]

 As a means for solving the above problems, a U-shaped metal fitting is inserted into a rectangular box body that is long in the front and rear, and a tightening screw is screwed into the U-shaped metal fitting from below the box body with the bottom wall of the box body interposed. The U-shaped metal fittings are vertically movable, and the fitting fixtures are installed side-by-side, and the fire wall made of non-combustible material such as metal or gypsum board is fixed with the fitting fixtures. I chose

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing only a left end portion of a fire wall A of the present invention and a holding fixture B of its mounting means, and FIG. 2 is an exploded perspective view of the holding fixture B. The fire wall A is a plate material 1 made of gypsum board that has been conventionally used in the interior of a house, and its front, rear, left and right end faces 1a are surrounded by edge members 1b for both reinforcement and end face treatment. The base body 2 of the clasping fixture B has a rectangular shape that is long in the front-rear direction. A through hole 2f is formed in the front portion of 2e. The U-shaped metal fitting 3 is formed by bending a thick steel plate so that the lower piece 3a and the upper piece 3c are parallel to each other, and a screw hole 3b is formed in the central portion of the lower piece 3a. The fastening screw 4 has a large diameter in the photograph 4a, and the fastening screw 4 is inserted from a through hole 2f formed in a front portion of the bottom wall 2e of the base body 2 and a lower piece of the U-shaped metal fitting 3 is inserted. 3a When screwed into the screw hole 3b formed in the central portion, the U-shaped metal fitting 3 is moved up and down inside the base 2 by twisting the tightening screw 4, whereby the upper piece 3c of the U-shaped metal fitting 3 and the base 2 are moved. The distance between the lip pieces 2c and 2d is adjustable.

FIG. 3 shows that the width of the right lip piece 2c of the base body 2 of the clasping fixture B shown in FIG. 1 is widened, and the parallel receiving piece 2'g is provided below the lip piece 2'c. Is installed side by side, and the left end of the fire wall A is inserted and supported on the receiving piece 2'g. The other parts are the same as those shown in FIG.

FIG. 4 shows another embodiment of the fire protection wall 5, in which the front and rear ends of a metal plate are raised to form front and rear walls 5a and 5b, and the upper end is bent in a front-back direction. Inward lip pieces 5c and 5d are formed, the left and right ends of the metal plate are raised to form left and right walls 5e and 5f, and upper end portions are formed as outward lip pieces 5g so as to face each other. It is selected whether to leave the space C surrounded by walls on the front, rear, left and right, or to insert the shielding plate D into the space C.

A fire wall is attached to the lower surface of the bottom plate E of the hanging cabinet installed above the sink with the above-described components. The mounting procedure is as follows. Loosen the tightening screw 4 provided on the lower surface of the front part of the base body 2 to widen the gap between the upper piece 3c of the U-shaped metal fitting 3 and the lip pieces 2c and 2d of the base body 2 and suspend in this space. The front end of the bottom plate E is inserted and the photograph 4a of the tightening screw 4 is twisted with fingers to attach the side end of the fire wall A together with the lip piece 2c.

FIG. 5 is a front view of a mounting portion mounted using the clasp fixing device B shown in FIG. 1, in which a fire wall A surrounded by an edge material 1b is superposed on the lower surface of the bottom plate E of the hanging cabinet. Then, the bottom plate E of the hanging cabinet and the front end surface of the fire wall A are inserted between the upper piece 3c of the U-shaped metal fitting 3 and the lip pieces 2c and 2d of the base body 2, and the screw 4a of the tightening screw 4 is twisted to twist the hanging cabinet. The bottom plate E and the fire wall A are integrally fixed to each other.

FIG. 6 is a front view of a mounting portion which is mounted by using the clasp fixing device B ′ shown in FIG. 3, and is a receiving member provided in parallel under a wide inward lip piece 2′c. The end of the fire wall A is inserted between it and the piece 2'g, and the tightening screw 4 provided on the lower surface of the clasp fixture is twisted to attach the fire wall to the lower surface of the bottom plate E of the hanging cabinet. .

FIG. 7 shows a structure in which the fireproof wall 5 shown in FIG. 4 is attached using the clasp fixing device B of FIG.

[Effect of the invention]

 When the fire wall of the present invention is attached to the lower surface of the hanging cabinet installed above the kitchen using the clasp fixing tool, it prevents the accidental flame generated by overheating of the gas stove and prevents the unexpected accident of the hanging cabinet. I can protect. In addition, the fire wall acts as a heat insulating material, and blocks radiant heat and steam generated from the stove to prevent deterioration of the bottom plate of the hanging cabinet. Furthermore, the stored items in the hanging cabinet can be protected from an abnormal environment.
