Abstract

PURPOSE:To perform the durability evaluating test in the actually using state by implanting the spikes of various kinds of spike shoes into the rim of a roller, which is reciprocated under the state of a constant load for the test piece of artificial turf that is tightly laid on a test stage. CONSTITUTION:Many screw holes are formed in a ring-shaped rim 11 constituting a roller 10 so that spikes S can be implanted. The spikes S are attached as the same arrangement and number as the spikes, which are provided at the bottoms of the spike shoes that are actually used. The weight of the roller is set so that the value is equal to the tread wheel of a Risson tester. The test piece of artificial turf is laid on a test stage in the tightened state. The spikes S corresponding to the spike shoes, which are used in various kinds of sports played on the artificial turf, are implanted into the rim 11 of the roller 10. The roller 10 is reciprocated on the test piece of the artificial turf under the constant load. Thus, the durability of the artificial turf can be evaluated in the actually using state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tester for evaluating the durability of flooring materials, especially artificial turf, and a test method therefor.

[0002]

2. Description of the Related Art The Lisson tester has been known as a tester for evaluating the durability of carpets. This Lisson test machine 1 has four legs 2a as shown in FIG.
And a frame 5 having a drive motor 3 and a suction hood 4 for rotationally driving the treadle 2,
It is composed of a guide 6 for guiding the reciprocating movement of the frame 5 and a test stand 7. And each leg 2a of the treadmill 2
On the other hand, a rubber bottom (not shown) is attached to the test stand 7, while the tip end 7a of the test stand 7 is formed in a semicircular shape and is assumed to be a corner portion of a staircase. Further, a clamp 8 is provided at the tip end 7a. (See DIN 54322).

Here, a sample carpet T is placed on the test stand 7.
After one end is fixed via a clamp 8, a weight 9 is connected to the other end to hang it down to make it tense, and the tread wheel 2 is reciprocally moved a predetermined number of times along the guide 6 while rotating the tread wheel 2 on the sample carpet T. It is what makes me. At this time, stepper 2
Applies a constant load to the sample carpet T, and further causes the peripheral speed of the legs 2a of the treadle 2 to be set slightly higher than the moving speed of the frame 5 to cause slip.

By the rotation and reciprocating movement of the treadmill 2 as described above, the durability of the sample carpet T is evaluated based on the mass reduction amount per unit area of the sample carpet T, the mass reduction rate per unit area and the appearance change. I am trying.

[0005]

By the way, the Lisson tester 1 is intended to evaluate the durability of a carpet or the like used indoors against walking. Therefore, it is assumed that a general sole is used as a treadmill. The second leg 2a is attached with a rubber sole. Therefore, when the durability of artificial turf which has rapidly spread in recent years is evaluated by the Lisson tester 1, a large amount of time is required until the appearance change due to abrasion is observed because the artificial turf has a high strength. Another problem is that the durability cannot be evaluated according to actual use.

The present invention has been made in view of the above problems, and provides a tester and a test method thereof capable of evaluating the durability of artificial turf according to actual use. .

[0007]

The artificial turf durability tester of the present invention comprises a test piece of artificial turf tensioned on a test stand, and a constant load applied to the test piece of artificial turf. It is characterized in that it is composed of a roller that reciprocates while rotating in the state of being set, and that spikes of various sports spike shoes can be directly planted on the rim of this roller.

Further, the artificial turf durability tester of the present invention is
It consists of a test piece of artificial turf laid on the test bench with tension, and a roller that reciprocates while rotating while applying a constant load to this test piece of artificial turf. It is characterized in that a band in which spikes of a spike shoe for a car are planted can be fixed.

Further, in the method for testing the durability of the artificial turf of the present invention, the test piece of the artificial turf is laid on the test stand in a tension state, and the arrangement and the number of spikes in the spike shoes actually used in this artificial turf. It is characterized in that the roller provided with spikes is reciprocally moved while being rotated with a constant load being applied to the test piece of the artificial turf.

[0010]

[Operation] An artificial turf test piece is laid on the test stand in a tensioned state, and a roller provided with spikes corresponding to the spikes of the spike shoe is rotated with a constant load being applied to the artificial turf test piece. Let it move back and forth.

As a result, the durability of the artificial turf can be evaluated in a short time according to the actual use of spike shoes.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a roller 10 used in place of the treadmill 2 of the Lisson tester 1, and spikes s can be planted on an annular rim 11 which constitutes the roller 10. A large number of screw holes (not shown) are formed. In this case, the spikes s are attached in the same manner as the arrangement and the number of spikes provided on the sole of the spike shoe that is actually used.

The weight of the roller 10 is set equal to the weight of the tread wheel 2 described above.

The artificial grass test piece is laid on the test stand 7 in a tensioned state, and spikes in spike shoes used in various sports performed on the artificial grass, such as golf, baseball, soccer, and hockey. After the spikes s are planted on the rim 11 of the roller 10 in accordance with the arrangement and the number of the rollers, the roller 10 is reciprocated while being rotated while a constant load is applied to the artificial grass test piece. As a result, the spike s penetrates into the pile of the artificial turf as the test piece, and the durability of the artificial turf used in the competition can be evaluated according to the actual use. Further, the strength of the base cloth of the artificial grass against the spike s can be tested together.

In this embodiment, a large number of screw holes are formed in the rim 11 of the roller 10, and spikes s are planted in the screw holes according to the arrangement and the number of spikes of the spike shoe. However, as shown in FIG. 2, a steel band 12 in which spikes s are planted according to the arrangement and number of spikes of spike shoes for various competitions is prepared in advance, and this band 12 is used for the rim 1 of the roller 10.
The durability test may be performed by wrapping around 1 and fixing with screws 13. In this case, it is only necessary to replace the band 12 corresponding to the spike shoe to be used, and therefore the preparation work can be greatly reduced.

[0017]

As described above, according to the present invention, it is possible to test the durability of the artificial turf by attaching the spike to the rim of the roller corresponding to the spike of the spike shoe that is actually used. The durability of can be tested in a short time according to actual use.
