Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a skate that is an improved version of the conventional roller skate.

[Conventional technology]

Conventionally, this type of roller skate has a roller made of plastic, the shaft of which is supported by a frame that extends downward from the bottom of the skate, and the roller is rotated to move straight on the bottom of the skate. Ta.

[Problem that the invention attempts to solve]

In the conventional roller skating technology mentioned above,
By the rotation of the roller provided on the bottom of the skate,
The vehicle is driven only in the front and back direction, and when making a curve, one leg is lifted off the floor, the center of gravity is placed on the other leg, and the curve is made in a large circle. But it's not an easy method, and you can't get extreme curves with this method.

In addition, the contact surface of the roller uses a hard plastic material, so it does not cause vibrations or noise when rotating.
There were problems such as slips and wear.

However, the rotation of the rollers lacked nimbleness.

The present invention aims to improve these problems.

[Means for solving problems]

In order to solve the problems of the conventional technology mentioned above,
As shown in FIGS. 1 to 6, (a) The ground-contacting part of the wheel 1, that is, the tread 2, is made of an elastic material such as rubber, and a protrusion is provided on the ground-contact surface to reduce vibrations generated during running. This prevents noise and slips from occurring.

(b) In order to make the rotation of the wheel 1 easier, a bearing 5 is provided around the shaft of the center shaft 3 at the center of the axis of the wheel 1, thereby achieving easy rotation and increasing speed.

(c) By moving the predetermined positions of the wing shafts 4 in opposite directions, the axle is displaced from the position of the solid line shown in FIG. 4 as shown by the dotted line, so the direction of the wheel 1 fixed to this axle is , a device that changes from the orthogonal direction X to the oblique direction Y is provided on the wing shaft.

Note that the axle direction can also be manipulated and displaced by providing a device (not shown) that can displace the axle direction in conjunction with the axle.

[Effect]

According to the present invention configured as described above, the wheel 1
During the rotation of the wheel 1, the rotation of the wheel 1 acts on the center shaft 3 very lightly since it is in contact with the center shaft 3 via the bearing 5 provided at the axial center of the wheel 1.

In addition, as shown in FIG.
are provided at the lower part of both wing shafts 4 in each row in the longitudinal direction at predetermined intervals, and between the two wing shaft balls 6, the wing shafts 4
support. The wing shaft 4 is fixed and locked in a predetermined position by the two wing shaft balls 6 and the upper horizontal portion of the window 9 provided in the frame 8. This wing shaft 4
When displacing the position on the wing shaft ball 6 from the solid line position to the dotted line position in FIG. , the direction can be changed.

The stop device 13 also serves to start, stop and change direction of the skate.

〔Example〕

An embodiment of the present invention will be described based on drawings 1 to 6. In FIG. 1, which is a front view showing the wheel of the wheel skate of the invention, and FIG. 2, which is a side view thereof, wheel 1
A tread 2 is provided around the ground surface of the tread 2, and a protrusion is provided on the surface of the tread 2. The tread 2 is made of an elastic body such as rubber and is made of a wear-resistant material. With the center shaft 3 having the same center axis as the virtual center axis of the wheel 1, rotation about the axis of the wheel 1 is transmitted to the center shaft 3 via the bearing 5 provided at the center of the shaft.

This bearing 5 allows the wheel to rotate easily. Note that a wing shaft 4 having the same axis as the virtual central axis of the center shaft is connected to both wings of the center shaft 3. A blade bearing 10 is provided which horizontally positions the blade shaft 4 and has a plurality of recesses arranged in parallel at predetermined intervals. In the illustrated embodiment, two balls are used to form a predetermined interval, but it may be a box-shaped wing bearing stand 12 having a recess for locking the wing shaft 4 as shown in FIG. .

A wheel 1 having a center shaft 3 and a wing shaft 4 as described above
is supported by the horizontal upper edge of a window 9 provided in a frame 8 hanging from the skate sole 11. Wing axis 4
is supported by the horizontal upper edge of the window 9 and a recess at the lower end.

When the wing shaft 4 is positioned, for example, in the concave portion at position c on each of the left and right sides in FIG. indicates the straight direction . The frame 8 having the wheels 1 constructed as described above is disposed on the skate sole 11, with one wheel at the front and two wheels at the rear, as shown in FIG. In addition, each of the left and right skate soles 11 is provided with a locking device 13 having a rectangular frame body.
will be established.

This stopping device 13 has one piece attached to the toe part of the skate sole 11, and its long side in a direction perpendicular to the direction of travel.
The other one is provided parallel to the direction of travel and on the inside of each foot.

This locking device 13 is provided with protrusions such as rubber elastic bodies on the outer surface, but may be provided with only a metal frame. This stopping device 13 starts and stops the skate, and changes direction by applying weight to one foot and kicking the ground surface outward by the stopping device 13 of the other foot.

[Effect of idea]

According to the structure and operation of the present invention as described above, first, (1) by using a rubber-like elastic member with protrusions on the tread of the wheel, vibrations, noise, slips, wear, etc. that occur during running are reduced; To prevent.

(2) By using a bearing in the contact area between the wheel and its shaft, the shaft and wheel rotate smoothly and easily, increasing speed.

(3) By changing the direction of the axle, the wheels change direction from straight to diagonal travel, and even beginners can change the direction from diagonal to straight travel.

(4) The stopping device starts and stops the skates.
This can be done by applying force to the ground surface. In addition, by putting your weight on one foot and using the stopping device on the other foot, you can easily change direction.

It has many effects such as
