Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller skate base.

[0002]

2. Description of the Related Art In some roller skates, a base made of synthetic rubber or the like has a stopper attached to the tip thereof.

However, this stopper is completely fixed and does not have any effective function for rotation during figure skating, unlike the case of ice skating.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to add a device to a skate base so as to enable a rotating performance.

[0005]

In order to solve the above-mentioned problems, in the present invention, a cylindrical body, which is rotatable in the circumferential direction and axially positionally adjustable, is located at a position higher than the roller ground contact surface at the tip of the roller skate base body. Was attached so as to project in the length direction of the base body.

[0006]

Since the cylindrical body is rotatable in a direction substantially orthogonal to the rollers of the roller skates, when the tip of the skating base stands, the skate base can swivel around the cylindrical body.

Further, when the roller is moving straight, the cylinder can be stopped by pressing the cylinder against the ground.

[0008]

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

As shown in FIGS. 1 and 2, the skate base of the present invention has a base body 1, a pair of front and rear rollers 2, 2a attached to the lower surface thereof, and a tip portion of the base body 1. It consists of a cylindrical body 3.

The base body 1 is usually made of plastic, iron plate, or aluminum die cast, and a shoe fastener is provided on the upper surface of the base body 1, or the shoe is directly fixed.

The cylindrical body 3 is made of rubber, synthetic resin or the like, has a taper shape that expands slightly outward, and is supported by a bolt 4 so as to be rotatable in the circumferential direction and positionally adjustable in the axial direction. There is.

The mounting structure of the cylindrical body 3 can be selected in various ways. For example, as shown in FIG. 1, a through hole 5 in an obliquely forward direction is provided at the tip of the base body 1, and a lower end of the through hole 5 is provided. A large-diameter portion 6 is formed, a female screw is cut upward from the large-diameter portion 6, and a bearing 7 and a disc spring 8 are attached to the large-diameter portion 6.

The bolt 4 is provided with a central hole 9 in which a reverse female screw is cut, and a small screw 10 having a reverse screw can be screwed into the central hole 9. Further, a cap nut 11 having a reverse female thread cut is embedded in the through hole 5,
It is fixed.

Now, an appropriate cylindrical body 3 is selected and rotatably attached by a bolt 4. At this time, the protrusion amount in the axial direction is appropriately adjusted by the washer 12 and the like. Then, the small-diameter screw 10 is screwed into the central hole 9 of the bolt 4. By doing so, the bolt 4 and the small-diameter screw 10 are reverse-threaded, so that the bolt 4 does not loosen.

The cylindrical body 3 must be located higher than the ground contact surfaces of the rollers 2 and 2a. However, the central axis does not have to coincide with the longitudinal centerline of the base 1, and may have a predetermined angle. The vertical angle can also be selected appropriately.

[0016]

As described above, according to the present invention, since the rotatable cylindrical body is attached to the tip of the base body of the roller skate as described above, it functions as a stopper in the forward direction and at the same time, the cylindrical body is centered on the cylindrical body. Since the skates can be rotated by using the skates, it is possible to easily perform an action such as a turn.
