Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for testing whether a rug such as a sponge mat laid on the floor of a bath or the like is slippery when a person's weight is applied.

[0002]

2. Description of the Related Art Conventionally, a sponge mat is often laid on the floor of a bath, but when a person puts his or her weight on the floor, it often slips and there is a risk of injury.
Since the sliding condition differs depending on the shape and material of the bottom surface of the sponge mat, it was necessary to develop a non-slip material. Therefore, it is necessary to prototype materials of various shapes and materials and to test the sliding condition of the materials, but since there was no means for such testing in the past, put a full-scale prototype on the floor. Therefore, there are times when a person's weight is multiplied and a sliding condition is tested.

[0003]

However, in the conventional test method as described above, it is difficult to objectively measure the sliding condition, and it is not always possible to apply a load under the same condition when applying a person's weight. It was difficult. Therefore, there is a problem that a highly reliable test cannot be performed. To develop a non-slip and easy-to-use mat, it is necessary to obtain objective test data with reliable numerical values, and the test data must be obtained with a reproducible test device. There is. However, the conventional test methods as described above have a problem that a reproducible, objective and highly reliable test cannot be performed, and a material that is hard to slip cannot be efficiently developed.

Therefore, the present invention has been made for the purpose of providing a device for objectively testing the sliding condition of a mat or the like by reproducing conditions close to actual usage conditions.

[0005]

A slip tester according to the invention of claim 1 applies a force to a plate-shaped material laid on a floor surface to
A testing machine for testing a sliding condition between a floor surface, a contact member having a contact surface parallel to the plate-shaped material, a slide member attached to a lower end, and the contact member, a floor surface. And a guide mechanism for sliding the slide member at a predetermined angle with respect to the floor surface from a state of being located at a predetermined height to a state of being in contact with the floor surface. A slip tester according to a second aspect of the present invention is a slip tester that tests the degree of sliding of a plate-shaped material with respect to the floor surface, wherein the guide mechanism is oblique to the support member erected from the floor surface. A slide member that is fixed and is slidable along this guide mechanism is provided. At the lower end of this slide member,
A contact member having a contact surface parallel to the floor surface is attached, and a slide angle setting mechanism for setting a sliding angle of the slide member with respect to the floor surface is provided.

[0006]

In the sliding tester according to the invention of claim 1, which takes the above means, a contact member having a contact surface parallel to the plate-like material laid on the floor is attached to the lower end of the slide member. The slide member slides at a predetermined angle with respect to the floor surface by the guide mechanism. Therefore,
When the slide member is pulled up, the contact member is positioned at a predetermined height from the floor surface, and then opened, the slide member slides and falls at the predetermined angle, and the contact member at the tip is the floor surface. It comes into contact with the plate-shaped material laid on the.
Due to the kinetic energy at this time, an oblique force acts on the plate-shaped material. The oblique force acting in this way simulates the force that acts on the plate-shaped material laid on the floor with a load applied to one leg. Therefore, at this time, the distance that the plate-shaped material slides on the floor becomes the data indicating the sliding condition in the test. If the height of pulling up the slide member is constant, it can be said that the force that falls and acts on the plate-like material is the same. Therefore, an objective test can be done. It is also possible to perform the test by changing the height at which the slide member is pulled up. Further, in the sliding tester according to the invention of claim 2, since the slide member is slidably provided along the guide mechanism obliquely fixed to the support member erected from the floor surface, the slide member is slidable. By pulling up and opening the member, the contact member attached to the lower end of the slide member applies an oblique force to the plate-shaped material on the floor.
The distance that the plate-shaped material slips at this time becomes the data indicating the sliding condition in the above test. The sliding angle of the slide member with respect to the floor surface can be set to an arbitrary angle by the slide angle setting mechanism, so that the angle of the force applied to the plate-shaped material can be variously changed and tested.
