Description

[0001]
[Technical field to which the invention belongs]
This invention relates to an inclined plate for eliminating a step in barrier-free operation.
[0002]
[Prior art]
With the aging of society, barrier-free is often required, and the following patent documents are available as means for eliminating steps such as doorways, thresholds, and frames.
[0003]
[Patent Document 1]
Japanese Patent No. 3058872 (paragraph 0008, 0009, FIG. 1)
[Patent Document 2]
JP-A-2000-179119 (abstract, FIG. 1)
[0004]
[Problems to be solved by the invention]
The prior art of Patent Document 1 has a complicated structure and is expensive, and the one of Patent Document 2 is a solid type which has not been reduced in weight and is inclined by the reaction force of the wheel when the inclined plate is raised in a wheelchair. There is a risk that the plate will shift backward.
[0005]
Further, when a non-slip tape is attached to the surface of the inclined plate, the tape may come off.
[0006]
In view of the above-mentioned problems of the prior art, the present invention aims at a simple structure, light weight and low cost, and prevents the inclined plate from being displaced rearward due to the reaction force of the wheels when the inclined plate is lifted up in a wheelchair. It is an object to provide an inclined plate in which a tape is hardly peeled.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the inclined plate of the present invention has a plurality of right-angled triangular bars, a bottom surface of the right-angled triangle having a hem portion, and a slope-forming plate having a top portion having an apex angle. The surface is provided with a plurality of grooves perpendicular to the inclination direction, and a non-slip tape of a shape adapted to the inner circumference of the groove is attached to the groove, and if necessary, the groove is formed. A groove is formed from both ends to the end of the slope forming plate, laminated wood is used as a material of the slope plate, and a rearward prevention means for the slope plate is provided on the back side of the slope plate. According to the present invention configured as described above, the structure is simplified by adopting the laminated wood and attaching the slope forming plate to the right-angled triangular crosspiece, so that the weight and cost can be reduced.
[0008]
In addition, by attaching a non-slip tape having the same shape to the groove, an effect of preventing the tape from peeling off can be obtained. By providing grooves at both ends of the groove, dust collected in the groove can be easily removed. Therefore, when the inclined plate is lifted up by the wheelchair by the rearward displacement preventing means, the inclined plate does not shift due to the reaction force of the wheels.
[0009]
[Embodiment of the invention]
Next, an embodiment of the present invention will be described with reference to the drawings. Four right-angled triangular bars 11 made of laminated wood are produced, and one end of a 2 cm-thick plate made of laminated wood is aligned with the base angle α of the right-angled triangular bars 11 and the other end is formed of the right-angled triangle. The groove 11 was cut in accordance with the apex angle β of the crosspiece 11, and a concave groove 12 having a width of 3 cm, semicircular ends at both ends, and a depth of 2 mm was formed on the surface thereof so as to be orthogonal to the inclination, and cut to fit the concave groove 12. A non-slip tape 13 is attached to the bottom surface of the concave groove 12, and a sweeping groove 14 (sweeping out dust) from both ends of the concave groove 12 to both ends of the laminated wood plate is provided to form a slope forming plate 15.
[0010]
The non-slip tape 13 is attached to the concave groove 12 by using an adhesive layer formed on the back surface of the tape itself, but other known attaching methods can be adopted.
[0011]
By attaching the non-slip tape 13 to the bottom surface of the concave groove 12 in this way, it is possible to prevent the wheel of the wheelchair or the sole of the pedestrian (not shown) from directly coming into contact with the edge of the non-slip tape 13 so as to prevent peeling. it can.
[0012]
The slope forming plate 15 is attached to the right-angled triangular bar 11 by a known adhesive method such as a wood adhesive, but may be attached with a nail or a wood screw. Is also good.
[0013]
A rubber plate 16 having fins inclined in the same direction as the inclination is attached to both or one of the back surfaces of the slope forming plate 15 and the right-angled triangle bar 11. When a load is applied to the inclined plate 10, the fin of the rubber plate 16 exerts a vector component force in the vertex direction of the inclined plate 10. Therefore, the inclined plate 10 does not shift rearward due to the reaction force of the wheels generated when the wheelchair goes up the inclined plate 10 or the reaction force of walking.
[0014]
In the above-described embodiment, the rubber plate 16 having the fins is attached. However, when the floor is not prevented from being damaged, a short nail may be implanted.
[0015]
[Effect of the invention]
As described above, according to the present invention, since the structure is simplified by adopting the laminated wood and attaching the slope forming plate to the right-angled triangular bar, the weight and cost can be reduced. By applying a non-slip tape having the same shape, an effect of preventing the tape from peeling off is obtained, and by providing sweeping grooves at both ends of the concave groove, dust accumulated in the concave groove can be easily removed. When the inclined plate is lifted up in a wheelchair by the displacement preventing means, the inclined plate does not shift due to the reaction force of the wheels.
