DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skater protection buffer which is arranged on the outside of a course of an ice skating rink.

[0002]

2. Description of the Related Art Conventionally, in an ice skating rink for sports, for example, when a skater running on a course falls over, a shock absorbing cushion is provided outside the course to prevent the skater from hitting a fence or the like and being injured. As such a buffer, for example, a cushion in which a cushion core material having cushioning properties such as urethane foam is covered with a covering material such as a rubberized cloth to form a mat is known. In addition, utility model registration No. 25331
No. 01 proposes a skater protection device in which such a buffer is supported by a support member.

[0003]

However, if such a buffer is installed near the course of a skating rink, only a specific portion is concentrated and damaged even though it is within its useful life, and the repair is performed. Etc. must be performed frequently. And as a result of investigating this damage situation,
It was found that the damage was concentrated from the lower part on the front side to the bottom side of the coating material.

[0004] Therefore, an object of the present invention is to reduce the labor and cost involved in repairing and maintaining a buffer used in a skating rink.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a buffer for a skating rink arranged near a course of an ice skating rink, wherein a cushion core is covered with a covering material. A reinforcing sheet was attached to at least a lower portion of the outer surface of the body main body on the front side facing the course.

As described above, by attaching the reinforcing sheet to the lower part of the buffer where the damaged part is concentrated, the trouble of repair and maintenance can be saved.

Here, as a result of the present inventors investigating the damage state of the cushion, as shown in the cross-sectional view of FIG. In the case of the front facing toward the side, if the vertical side is the rear side, the damaged portion is from the lower end a of the front surface of the coating material 53 to the point b 20 to 30 cm above and the front end a of the bottom surface about 20 cm. It was concentrated in the range up to the point c where it entered, and although the degree of damage varied considerably, most of the tears were about 2 to 20 cm, and this range was in a state of tearing.

[0008] From these damage modes, the cause of the tear is rarely the case where a skater or the like falls down and is damaged by the blade of a skating shoe. However, it was found that most of them were hit by the skate blade when trying to grab the buffer instead of the handrail.

[0009] In view of the above, particularly, such a place where damage is frequently caused is covered with a reinforcing sheet and protected. At this time, a mounting portion is in a range from a lower end portion a on the front side facing the course to a point b. Is preferably covered, and in addition to this, it is more preferable that the bottom surface is also covered in a range from the tip a to the point c.

[0010] Here, the reinforcing sheet is excellent in cold resistance and water resistance, and has tear strength and tensile strength so as not to be easily torn when hit by a skate shoe blade. A small and flexible sheet material is preferable, and for example, a tarpaulin, a laminate of a tarpaulin and a resin film, a Kevlar, or the like can be used. In addition, the mounting of the reinforcing sheet may be configured integrally with the cushioning member, but if it is detachable, replacement work in case of damage becomes easy, and repair work can be removed and treated. preferable.

According to a second aspect, the tear strength of the reinforcing sheet is 30 to 70 kgf, and in a third aspect, the tensile strength of the reinforcing sheet is 400 to 700 kgf / 3 cm.
And

By setting the tear strength and the tensile strength in such ranges, it is possible to make it hard to be damaged even when a cutter knife or the like is applied thereto, and to become hard to spread even if the hole is pulled and then pulled. Therefore, it is suitable as a material for preventing damage.

Embodiments of the present invention will be described with reference to the accompanying drawings. Here, FIG. 1 is a plan view of an ice skating rink, FIG. 2 is a perspective view showing a configuration example of a buffer for a skating rink, FIG. 3 is a sectional view taken along line AA of FIG.
FIG. 5 is a front view of a state in which the second reinforcing sheet is removed, and FIG.
It is a bottom view in the state where the sheet for reinforcement was removed.

The location S of the skating rink buffer 1 according to the present invention is such that, for example, in a lap course 3 of an ice skating rink 2 as shown in FIG. In order not to be injured, especially the outside of the course 3 such as a corner portion is mainly used. For example, the buffer 1 as a unit has a trapezoidal block shape as shown in FIG. Is set to about 2 to 3 m, and can be connected in the length direction.

That is, as shown in FIGS. 2 and 3, the shock absorber 1 according to the present invention has a shock absorber main body 4 having a trapezoidal cross section.
And a first reinforcing sheet 5 and a second reinforcing sheet 6 mounted on the front side of the buffer body 4. The buffer body 4 has substantially the same structure as the conventional structure, and is made of urethane foam or the like. Is covered with a covering material 8 such as a rubberized cloth.

At this time, the covering material 8 is selected from materials which have an appropriate flexibility, a good shape retention when urethane foam is put in, a good workability, and a reasonable cost. In the embodiment, a rubberized cloth topped with a nylon cloth of 420 denier with a high-pallon rubber on the surface and a chloroprene rubber on the back, having a thickness of 0.80 mm, a weight of 1130 g, a tensile strength of 140 kgf / 3 cm, and a tear strength of 12 kgf. It is a material of a degree.

The buffer body 4 is installed in such a manner that the inclined surface of the trapezoidal cross section is the front surface facing the course 3 and the vertical surface is the rear surface. A fastener 9 is provided from both sides except the front side to the rear side, and the covering material 8 can be closed or opened in a bag shape through the fastener 9. By opening the fastener 9, the cushion core 7 can be taken in and out. Incidentally, the material of the covering material 8 may be any material as long as it is a flexible sheet having excellent cold resistance and water resistance and has the required tensile strength and tear strength, for example, urethane tarpaulin or the like.

The first reinforcing sheet 5 is provided from the front surface to a part of the bottom surface of the buffer body 4 which is frequently damaged. In the embodiment, the first reinforcing sheet 5 is sewn to the covering material 8 by sewing or the like to be integrated. ing. A second reinforcing sheet 6 is detachably provided on a lower portion of the front surface of the buffer body 4 where the damaged portion is further concentrated.
By making the second reinforcing sheets 5 and 6 have a double structure, damages are particularly unlikely to occur.

The first reinforcing sheet 5 and the second reinforcing sheet 6 are made of a rubberized cloth which is high in tear strength and tensile strength, is hardly damaged, and is flexible. A double-layer, five-layer rubberized cloth is provided in which two layers of Hypalon rubber are topped on the surface of a double base cloth of nylon 840 denier, and two layers of chloroprene rubber are topped on the back side.

The rubberized cloth of the first reinforcing sheet 5 and the second reinforcing sheet 6 has a thickness of 1.39 mm, a weight of 1790 g, and a tensile strength of 500 to 550 kgf / 3c.
m, the tear strength is 45 to 50 kgf, and it is suitable because it is hardly damaged even when a cutter knife or the like is applied, and the wound does not expand even if a tensile force acts when a hole is made.

At one end of the front surface of the first reinforcing sheet 5, a male and female one-sided surface fastener 11b for connecting to the adjacent buffer 1 is attached. The hook-and-loop fastener 11b is also attached to the end surface of the hook-and-loop fastener 8;
1a is provided so as to protrude, and the hook-and-loop fasteners 11a and 11b adjacent to each other are engaged to enable connection in the longitudinal direction.

As shown in FIGS. 4 and 5, on the lower front edge and the bottom edge of the first reinforcing sheet 5, one of male and female sides for making the second reinforcing sheet 6 detachable is provided. The hook-and-loop fastener 12b is attached, and the hook-and-loop fastener 12a of the other sex is attached to the peripheral part of the back side of the 2nd sheet 6 for reinforcement.

Incidentally, the second reinforcing sheet 6 is formed in a rectangular shape having the same length as the length of the buffer 1 and a width of about 40 cm. When the second reinforcing sheet 6 is folded in a substantially L shape as shown in FIG. , A region from the lower end of the front surface of the buffer 1 to an upper portion of 30 cm, and a region about 10 cm deeper from the front end of the bottom surface can be covered.

If a tarpaulin using aramid fiber such as Kevlar is used as a material for the first and second reinforcing sheets 5 and 6 as described above, the cost is high but the damage is prevented. From the viewpoint, it is more preferable. Further, as the second reinforcing sheet 6, a laminated sheet in which a polyethylene film or the like is laminated on the surface of a tarpaulin may be used. By laminating a material having excellent smoothness on the surface of the tarpaulin in this way, abrasion resistance is improved, and small scratches are less likely to occur, thereby improving durability.

In the buffer 1 configured as described above,
In particular, the first reinforcement sheet 5 covers the uppermost part of the front surface and a part of the bottom surface, and the second reinforcement sheet 6 covers the lower part of the front surface and a part of the bottom surface. The portion from the front lower portion to a part of the bottom surface can be double protected. As a result, the durability is improved and the frequency of repair can be reduced.

Further, since the second reinforcing sheet 6 is detachable, it can be easily replaced when it is damaged, for example, and it is expected that the frequency of damage will be higher than that of other parts depending on the arrangement location and the like. In such a case, it is possible to replace the second reinforcing sheet 6 with a material having a higher rigidity, and the like, and the operation can be performed more flexibly.

The present invention is not limited to the above embodiment. Those having substantially the same configuration as those described in the claims of the present invention and exhibiting the same operation and effect belong to the technical scope of the present invention. For example, the second
The reinforcing sheet 6 may be a fixed type instead of a detachable type,
In addition, in the case of a detachable type, a braided type, a fastener type, etc. can be adopted other than the hook-and-loop fastener. The configuration in which the entire area on the front side is covered by the first reinforcing sheet 5 is not necessarily an essential requirement.

[0028]

As described above, the cushioning body for a skating rink according to the present invention has at least a lower portion on the front side facing the course, of the outer surface of the cushioning body formed by covering the cushion core with the covering material. The reinforcing sheet is attached to the area, which increases the protection function where damage tends to concentrate,
Repair and maintenance work can be saved. Further, the tear strength of the reinforcing sheet is set to 30 to 7 as in claims 2 and 3.
0 kgf, and the tensile strength is 400-700 kgf / 3
If it is set to cm, it will be difficult to be damaged and the wound will not be easily expanded, which is preferable.
