Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an artificial skating rink floor formed by interconnecting plate-like block members made of synthetic resin.

Olefin resins such as polyethylene with large molecular weight are
It has low frictional resistance and is suitable for use as an artificial skating rink floor.

However, it is extremely difficult to manufacture a large floor area like a skating rink floor with a single synthetic resin board, and
A single plate cannot absorb the expansion and contraction caused by temperature changes.

Therefore, the skating rink floor is usually divided into a number of blocks and connected with connectors.

In this case, since the man-hours involved in joining a large number of blocks constitute a large part of the installation of the skating rink floor, it is desired to develop a connecting device that does not require much effort.

It is also necessary to connect the blocks so that the sliding surface is as flat as possible and the edges of the skates do not get caught in the steps or gaps between the joint surfaces of the blocks, and the connector must also meet these requirements.

The present invention has been made with the object of providing a skating rink floor that can fully meet the various demands mentioned above.

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

Plate-shaped block member 1 making up the skating rink floor
is made of an olefin resin such as polyethylene having a large molecular weight, and its front and back surfaces are roughened with irregularities 2.

The block member 1 is rectangular as shown, and has a thickness sufficient to withstand the weight of the skater and other forces.

A large number of such block members 1 are joined to each other at their side surfaces and connected by a connector 5, which will be described later, to form the scale 1 to the link floor.

The connector 5 is an elongated channel-shaped member consisting of a bottom side 6 and vertical sides 7 rising from both ends of the bottom side 6 at a substantially right angle.

The connector 5 can be made of any suitable material, but is preferably made of the same olefin resin as the block member 1.

On the lower surface of each block member 1, a groove 3 is provided near the edge of the block member 1 along the edge, and a groove 3 is cut along the lower surface near the edge so that the connector 5 can be fitted into the lower surface of the block member 1. A notch 4 is formed.

The adjacent block members 1, 1 are connected to the vertical sides 7, 1 of the connector 5,
7 into the grooves 3, 3 of the block members 1, 1, and the bottom portion 6 of the connector 5 into the notch 4 of the block members 1, 1, thereby connecting them to each other.

At that time, the surfaces of the adjacent block members 1, 1 are made substantially horizontal so that no steps or gaps occur at the joint surface S.
The thickness of the vertical side 7 of the connector 5 and the width of the groove 3 of the block member 1, and the thickness of the bottom side 6 of the connector 5 and the depth of the cutout 4 of the block member 1 are substantially equal, and Adjacent block members 1, 1 are connected by a connector 5 over the entire length of their edges.

In order to form a skating rink floor with the block member 1 and connector 5, the connector 5 is placed on the floor of the building, the block member 1 is placed thereon, and the block member 1 is connected in the manner described above. They can be connected using tool 5.

Since the skating rink floor according to the present invention is as described above, its assembly is quite simple, and the skating rink floor can be laid in a short time by a small number of people.

In particular, in the present invention, since the adjacent block members 1, 1 are connected over the entire length of their edges by the connector 5 consisting of the bottom part 6 and the vertical parts 7, 7, the horizontal direction of the block members 1, 1 is The movement is carried out over its entire length by the vertical sides 7, 7 of the connector 5.
The joint surface S of the block member 5 is completely prevented from moving downward by contacting the bottom part 6 of the connector 5 over its entire length, so that the joint surface S of the block members 1, 1 The occurrence of gaps or differences in level is completely prevented.

Therefore, there is no fear that the edge of the skate will get caught on the joint surface S of the block members 1, 1, and the user can enjoy skating cheerfully and with peace of mind.

The uneven rough surface 2 formed on the surface of the block member 1 functions to reduce frictional resistance by retaining lubricants such as water-soluble oil and finely powdered tiles sprinkled on the skating rink floor. On the contrary, the formed uneven rough surface 2 acts as a frictional resistance and prevents the skating rink floor from shifting.

In addition, upward movement of the block member 1 is unlikely to occur due to its own weight and the weight of the skater, but just in case, a horizontal groove of a predetermined width is installed at the intermediate position of the joint surface S of the adjacent block members 1, 1. are provided in each of the block members 1.1, and by inserting one plate member into the groove, upward movement of the block member 1 is completely prevented.

Claims (1)

[Scope of utility model registration request] In a skating rink floor formed by joining the side surfaces of plate-shaped block members made of olefin resin and connecting them with a connecting device, the connecting device consists of a bottom portion and a vertical portion rising approximately at right angles from the bottom portion. The lower surfaces of adjacent block members have a groove having a width approximately equal to the thickness of the vertical side of the connector near the edge of the block member and along the edge. A notch is formed by cutting out the lower surface near the part along the edge, and the notch has a depth approximately equal to the thickness of the bottom of the connector, and the vertical part of the connector can be inserted into the groove of the block member. A skating rink floor characterized in that the bottom part of the connector is fitted into a notch in the block member, and the block member is connected to the block member over the entire length of its edge by the connector.
