DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to lay mud and dust adhering to shoe soles and the like from the outside by laying it at entrances of various buildings and rooms, such as cafeterias and hospitals, which dislike bringing mud and dust. The present invention relates to a dust removal mat that can be collected by suction.

[0002]

2. Description of the Related Art Conventional dust removing mats include, for example, a "mat" described in Japanese Utility Model Publication No. 4-31023 and a "shoe wipe mat" described in Japanese Patent Application Laid-Open No. 58-157431. Etc., all of which exert suction of a dust collector or a vacuum cleaner in the internal gap chamber of the mat body,
It is designed to suck mud and dust accumulated in the gap chamber to the outside.

[0003]

However, in each of the above-mentioned conventional dust removing mats, the upper mat body and the lower mat body are integrally mounted with a vertical space therebetween, and a suction force is exerted on the intermediate chamber provided at this space. Due to the structure that collects dust, the structure is complicated and the number of parts is large, so the production cost is high.If there is mud or dust in the intermediate room that can not be sucked by a dust collector or vacuum cleaner, cleaning is extremely difficult. In addition, there is a problem that the overall thickness is increased due to the combination of the upper and lower mat bodies, and a large step is formed between the mat and the surrounding floor.

[0004] Therefore, the technical problem of the present invention is to simplify the overall structure of the dust removing mat and reduce the manufacturing cost, while simplifying the cleaning by adopting a structure that does not accumulate mud, dust, etc. inside, and at the same time. The purpose is to make the thickness as thin as possible so that the step with the periphery is made as small as possible.

[0005]

Means taken by the present invention to solve the above-mentioned technical problems are as follows.

[0006] By applying a suction force of a dust collector or a vacuum cleaner to an inner gap portion of the mat body having the upper mat surface as a wiping surface, dirt or dust dropped on the wiping surface is collected. In the dust mat constructed in

(1) The entirety of the mat body is formed in a substantially suction cup shape with a bottom surface opened and a peripheral portion sealed. The inside of the mat body is suctioned by the dust collector or the vacuum cleaner. While forming a plurality of suction slits that are opened by the treading pressure on the upper layer mat surface at intervals while forming an inner gap portion covered by the upper layer mat surface, a plurality of suction slits are formed on the bottom surface of the upper layer mat surface to maintain the interval between the inner gap portions. With the support column facing down.

(2) The upper layer mat surface is a wiping surface on which a number of brush-like protrusions are protruded, and a large number of treading protrusions, which are stiffer than the brush-like protrusions, protrude upward from the wiping surface.

(3) The entire mat body, and the stepping projections and the support pillars projecting from the upper and lower surfaces of the upper mat surface are integrally formed using a flexible material.

(4) Between the suction slits formed at intervals on the upper mat surface, a support column for maintaining the space of the inner gap portion is provided on each bottom surface at a position close to one of the suction slits. On each upper surface of the bent plate that projects downward and is bent downward by the tread pressure to open the suction slit,
Each of the tread protrusions is projected upward.

(5) At the bottom of each bent plate which is bent downward by the treading pressure to open the suction slit, the bent slit plate is pushed back to the original position when the treading pressure is released, and the suction slit is closed. An elastic support that is supported in a state is suspended.

(6) The upper surface of the upper mat surface is a wiping surface made of a porous material.

[0013]

The respective means described in the above (1) to (6) operate as follows.

According to the means described in the above (1), when a user rides on a mat and weighs, the weight (stepping pressure) is applied.
Since the suction slit formed on the upper mat surface opens, the air is intensively sucked from here, and at the same time the mud and dust adhering to the sole of the shoe are also suctioned. It is possible to collect dust on the dust collector or the vacuum cleaner side through the section.

Further, according to the means described in the above (1),
Even if the user rides on the mat, the large number of support columns maintain the gap between the inner gaps, so that the suction power of the dust collector or the vacuum cleaner can be intensively applied to the opened suction slit without any trouble. In addition, since the mat body has a structure with an open bottom surface, the whole body can be easily and thinly formed, and when mud or dirt remains in the inner gap, the mat body is placed on the floor. Lifting from the surface allows them to be easily cleaned or cleaned.

According to the means described in the above (2), when the shoe rides on the mat, a gap is formed between the sole of the shoe and the brush-like protrusion protruding from the mat surface of the upper layer. Since the suction force of the dust collector or the vacuum cleaner reaches the gaps between the brush-like protrusions through the suction slit, the suction or suction opening of the mud or dust dropped between the brush-like protrusions from the shoe soles. In addition to being able to be sucked to the slit side, when the sole of the user steps on the stepping projection, the stepping pressure enables the suction slot to be reliably and effectively opened.

According to the means described in the above (3), since the entire mat body including the stepping projections and the support columns is integrally formed using a flexible material such as rubber or plastic, the dust removing mat is extremely simple. In addition to being able to manufacture at low cost, a suction slit that is open even with repeated treading pressure, or a treading projection and a support column sufficiently exhibit restoring force to release treading pressure. As a result, it is possible to quickly return to the original state, that is, the suction slit is closed, and the treading protrusion and the support column are respectively protruded up and down.

According to the means described in the above (4), when the user receives the stepping pressure, the support column receives the stepping pressure and presses and bends the bent plate largely downward. The suction force of the dust collector or the vacuum cleaner can be made to work effectively, but furthermore, since the stepping projection is provided on the upper surface of the bent plate so as to project upward, the shoe sole steps on the stepping projection, Opening the suction slits to a greater extent makes it possible to concentrate the suction force.

According to the means described in the above (5), the bent plate which is bent downward by receiving the stepping pressure of the user, when the stepping pressure is released, the elastic support returns the bent plate to the original position by the restoring force. Since it is pushed up, the suction slit can be reliably returned to the closed state.

According to the means described in the above (6), the wiping surface made of the porous material provided on the upper surface of the upper layer mat is
By exerting the same wiping effect as the brush-shaped protrusion described above, it is possible to cleanly remove mud or dust adhering to the sole of the shoe, and to suction and collect the dust or the vacuum cleaner.

As described above, the technical problems described above can be solved by the above-described means, and the problems of the conventional technology can be solved.
