Description

  The present invention relates to an elastic floor mat having a recognition and identification function for movement of a visually impaired person (for example, a blind person, a low vision person, etc.).

Conventionally, braille blocks and tiles as shown in FIG. 4 of Patent Document 1 have been laid in a station building or a passage of a public building as means for guiding a visually impaired person to walk. Some of these braille blocks and tiles embed or adhere to the floor surface of a square or rectangular block provided with irregularities that help guide pedestrians on the surface. Further, a mat disclosed in Patent Document 2 is known as a mat that protects feet, waists, and the like of workers such as workplaces and kitchens that mainly perform standing work from fatigue and obstacles.
Japanese Patent Laid-Open No. 2002-250016 (second page, FIG. 4) JP 2000-70108 A (FIG. 2)

  However, braille blocks installed as described above have surface irregularities and steps, etc., so that visually impaired people and physically handicapped people can fall by walking while walking, wet in the rainy or snowy season, etc. There is a risk of falling due to icing.

  Also, in hospitals and facilities for the physically handicapped, when driving a wheelchair, moving bed, etc., straight running is hindered by unevenness and steps on the surface of the block, giving a large vibration and causing a heavy burden and danger to the patient etc. The use of braille blocks is currently prohibited in hospitals.

  In addition, when a braille block is newly installed on an existing floor, the existing flooring is cut out with the width of the braille block and embedded by embedding the braille block into the cut portion because it has a thick structure. There is a need. As described above, time and labor are required for the excision work of the floor surface and the embedding work of the braille block, and the cost is high.

In addition, Patent Document 2 for protecting the feet and waists of standing work is effective in preventing fatigue and obstacles of the feet and legs, but the structure is complicated and the cost is high and the weight is large. There was the fault that handling was also inconvenient.
The present invention is intended to solve or improve these problems.

An elastic floor mat of the present invention for solving the above-mentioned problem is firstly a mat 1 made of a sheet-like or plate-like elastic member having a certain thickness and laid on the floor surface. The upper surface on both side ends is an edge portion 3 formed of a gently descending inclined surface, the central portion is formed thicker than the edge portion 3 and is an elastic portion 2 rich in elasticity. Each mat 1 includes a gap portion 4 formed of an upward concave portion having a predetermined depth and a plurality of projection portions 6 that protrude downward into the gap portion 4 and whose lower end surface is elastically in contact with the floor surface side. An end wall portion 9 having the same height as the thickness of the mat 1 is formed on one or both of the front and rear ends of the elastic portion 2, and the front and rear ends of the mat 1 laid with the end wall portions 9 adjacent to each other. Formed as concave and convex joint portions 11 that are fitted and locked to each other, and end wall portions of the respective joint portions 11 The protrusion 6 is characterized in that it is projected within.

Second , the circumferential surface of the protrusion 6 is formed in a tapered surface or a curved surface so as to taper toward the ground contact surface.

Third , the contact surface of the protrusion 6 is a concave suction surface 7 curved upward.

Fourth , the upper surface of at least one end of the front and rear ends of the mat 1 is characterized by an end edge portion 8 having a gently descending inclined surface.

Fifth , the mat 1 is exposed to a non-slip surface having a fine uneven surface on the exposed surface.

  According to the buffer floor mat of the present invention configured as described above, the following effects can be obtained.

(1) By making the upper surface of the edges on both sides of the mat a gentle downward sloping surface, the level difference between the floor surface and the mat is eliminated, and in addition to preventing falling by rolling, wheelchairs and mobile beds Vibration can also be suppressed. In addition, since the elastic portion is composed of a gap formed by an upward concave portion having a predetermined depth on the ground surface side, and a large number of elastic protrusions projecting downward in the gap, it is an edge for pedestrians and the like. The tactile sensation between the portion and the elastic portion, or the existing floor surface and the mat or the elastic portion is different. As a result, the visually handicapped person has an advantage that the visually handicapped person can be surely guided by sensing a feeling of landing at the time of walking, a touch feeling of a white cane, and a change in sound.

(2) By forming the peripheral surface of the protrusion into a tapered surface or a curved surface so as to taper toward the ground contact surface, the tapered ground contact surface side of the elastic protrusion has a pressure from the upper surface of the elastic portion. It is possible to efficiently absorb the surface and improve the elasticity of the elastic portion.

(3) By making the ground contact surface of the protrusion a concave suction surface curved upward, the function as a sucker works on a smooth floor surface, and the mat can be fixed to the floor surface. It is possible to prevent the deviation.

(4) The end wall portions are formed at the front and rear ends of the elastic portion of the mat, and the mat mat has the same thickness as the mat because the end portions of the adjacent mats engage and fit with each other. Since it becomes the joint part of height, while the fixation of the connection of mats increases, the walk surface of a mat can be walked without stress by joining of a joint part.

(5) The upper surface of at least one end of the front and rear ends of the mat is an edge that consists of a gently descending slope, which prevents the mat from tipping over at the start and end of the mat, as well as when running a wheelchair or moving bed. The vibration of can also be suppressed.

  Hereinafter, a case where an embodiment of the present invention is applied to a guiding mat will be described with reference to the drawings. 1 and 2 are perspective views showing the front and back surfaces of the mat of the present invention, and FIGS. 3 and 4 are AA and BB sectional views, respectively, of FIG.

  The mat 1 is provided with a central elastic portion 2 and edge portions 3 on both side ends, and is made of rubber or synthetic resin material or foamed material having a certain elasticity, and the edge portion 3 has a step with the floor surface. In order to eliminate this, an inclined surface is formed such that the upper surface is inclined downward toward the outer end. For example, although it depends on the thickness of the mat 1, the inclination angle of the edge 3 is formed to be about 2 ° to 15 ° so as not to feel an impact on the traveling of the wheelchair. Further, the inclined surface is not necessarily a flat surface, and may be a rounded arc-shaped cross-sectional surface. The material of the mat 1 may be a transparent material, and in that case, a marker such as a transparent arrow can be inserted between a portion between the mat 1 and the floor surface.

  In addition, a concave gap portion 4 having a predetermined depth upward is provided on the grounding surface side of the elastic portion 2, and a large number of protrusions 6 protrude downwardly at equal intervals in the gap portion 4. It is configured to give elasticity to the elastic portion 2 by elastically contacting the floor surface side. In this example, the protrusion 6 has a substantially cylindrical shape, and its peripheral surface is tapered toward the ground contact surface in a tapered shape or a quadratic curve shape, and the edge of the lower end surface of the protrusion 6 is curved. It is chamfered into a shape. Then, as shown in the cross-sectional views of FIGS. 3 and 4, a concave suction surface 7 is formed on the ground contact surface at the tip of the protrusion 6.

  Further, as shown in FIG. 1, an end mat 1 ′ is provided at the start or end of the mat 1, and an end edge 8 is formed at the start or end of the end mat 1 ′. Similar to the edge 3 described above, an inclined surface that is gently inclined in an oblique direction toward the terminal end or the starting end is formed. The exposed surfaces of the mats 1 and 1 ′ are subjected to anti-slip processing by a method such as forming a fine concavo-convex pattern consisting of a striped pattern, a dot pattern or any other pattern, or attaching a sandy object. (See FIG. 1).

  Explaining the joining of the mats 1, the end wall 9 having the same height as the thickness of the mat is formed on both the front and rear ends of the elastic part 2 of the mat 1, and the end wall 9 is adjacently laid. The concave-convex joint 11 is provided so that the ends of the first and second ends engage with each other. In this example, the joint portion 11 is a joint that is fitted and locked to each other. In the end mat 1 ′, an end edge 8 is formed at one end in the front-rear direction, and an end wall 9 and a joint 11 are formed at the other end in the same manner as the mat 1. The parts 11 are engaged with each other and engaged and locked.

  At the time of construction, the mat 1 formed in a relatively short unit length is bonded and fixed to a predetermined position such as a floor, and the joint portions 11 are fitted and locked to each other. Therefore, even in the case of laying on an existing floor surface, unlike conventional Braille blocks, it has become possible to lay without digging the floor. In addition, because it can be laid by bonding and fixing to the existing floor using double-sided tape, it can be easily repaired and replaced, and if it is temporarily installed at a conference or event venue, it can be placed without bonding to the floor. But it can be used.

  FIG. 5 shows the mat 1 and the end mat at the intersection of the taxiway using the mat 1 and the end mat 1 ′ without manufacturing cross members such as a cross road, T-shaped road, L-shaped road, and Y-shaped road in advance. The example which comprised the intersection using only 1 'is shown. However, FIG. 5 shows only when a cross road is formed. In this example, the part where the guideway intersects is a flat space where the floor surface is exposed as it is, so that, for example, when a visually handicapped person is walking normally, a white cane (foot) or a foot is in contact with the floor surface. The difference in the sensation makes it sense that the vehicle is at an intersection, thus enabling clearer identification.

  The mat configured as described above can be used not only as a guide mat for pedestrians and the like, but also as a buffer mat for laying in a standing work position for a worker who performs a standing work in various work places, for example. The shape in plan view is not limited to a rectangular shape, and may be a square, a circle, or other polygons. Further, the end mat 1 'has a structure in which end corners are processed into corners, but the end portions or both corners can be formed in a round shape.

  The elastic floor mat of the present invention can be used not only as a walking guideway for visually handicapped persons, but also as a guidance for exits of buses and trains, as a destination guidance display such as a display of a boarding position at a bus stop or platform, etc. It can also be widely used as a slipper in baths, airports, and stations. In addition, when used in combination with a conventionally known voice guidance device, accurate walking guidance for visually impaired persons can be achieved.

  In the above embodiment, the elastic portion 2 is shown at the center of the mat 1, but the elastic portion 2 is not provided in terms of durability, cost, etc. when used as an outdoor induction mat or the like. Can also be used. The function in this case is to make a pedestrian or the like sense the difference between the floor surface of concrete, asphalt, tile or the like and the texture of the mat, and the other functions are the same as those in the above embodiment.
