Claims:
What is claimed is:

1. A roller skates with an adjustable horizontal dimension, comprising: a truck having a groove and sliding slot, a heel cap connecting the truck, and having a anchor section, an adjusting block connecting the spring into the groove; and a buckle plank connecting the spring in to the groove, and having a across bolt; when adjusting the size of the shoes, The adjusting block is connected a spring having a resilience function to adjust horizontal dimension size.

2. A roller skate with an adjustable horizontal dimension as claimed in claim 1, wherein the anchor section is bevel tooth.

3. A roller skate with an adjustable horizontal dimension as claimed in claim 2, wherein the bevel tooth angle is 0°˜90°.

4. A roller skate with an adjustable horizontal dimension as claimed in claim 1, wherein the anchor section and a hell cap is integrated.

Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to a roller skate, and more particularly, to one that provides a mechanism for adjusting the horizontal dimension of the shoe.

2. Description of the Related Art

Whereas U.S. Pat. No. 6,918,602 describes that a roller skate with an adjustable longitudinal dimension for adjusting the dimension of the shoe cap of the roller skate includes an anchor section. The anchor section to enable the cap to move forwards or rearwards when the elastic element is depressed, the two coupling section latched together to anchor shoe cap.

But in actual use, while adjusting the shoe size to fit us, the two-piece shoe cap needs spending more time for adjusting the shoe size, and while skating, sometime we do some big action, for instance, jump or stop urgently, the big action have a stress concentration phenomenon, if the stress is to large too two coupling section match loose, then endanger the security of the user.

The present invention intends to provide a roller skate with an adjustable horizontal dimension which is used to adjust horizontal dimension more than move quickly and easy to adjust, and the spring have a reacting force which is used to enhance the structure intensity for combine the heel cap with truck by to mitigate and overcome the above problem.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a roller skate with an adjustable horizontal dimension which includes an adjusting block, a buckle plank and an anchor section. The adjusting block is connected a horizontal spring to having a resilience function for adjusting horizontal dimension.

The secondary objective of the present invention is to provide a roller skate with an adjustable horizontal dimension which includes an adjusting block, a buckle plank and an anchor section. The buckle plank is anchor an anchor section with the vertical spring which has a reacting force which is used to enhance structure intensity for combine the heel cap with truck.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description and the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring initially to FIGS. 1, 2 and 3, a roller skate 1 includes a truck 10, a groove 11, a sliding slot 12, a housing trough 13, a heel cap 20, an anchor section 21 a tooling section 22, an adjusting block 30, a horizontal spring 31, a spring pillar 32, a buckle plank 40, an across bolt 41, and a vertical spring 42.

Referring to FIGS. 1, 2 and 3, the pattern in accordance with the embodiment of the present invention includes an adjusting block 30, a buckle plank 40, an anchor section 21 and a horizontal spring 31, the truck 10 has a groove 11 and a spring pillar 12. The horizontal spring 31 is connected with the adjusting block 30 in the groove 11, and the horizontal spring 31 has a resilience is used for adjusting horizontal distance, the truck 10 has a sliding slot 12, the adjusting block 30 and the horizontal spring 31 are used to adjust the position between the heel cap 20 and the truck 10 on the sliding slot 32.

Referring to FIG. 4 and 5, the heel cap 20 has a anchor section 21 on the undersurface, one end of the buckle plank 40 is fixed on the truck 10, the buckle plank 40 is connected with the vertical spring 42 on the spring pillar 32′, and the vertical spring 42 has a reacting force to anchor between the tooling section 22 and the across bolt 41. When pressing the buckle plank 40, the tooling section 22 and across bolt 41 are separated to adjust the horizontal dimension between the heel cap 20 and the truck 10, and when adjusting the best horizontal dimension, the vertical spring 42 has a reacting force which is used to enhance structure intensity for combine the heel cap 20 with truck 10.

Although the invention has been described in detail with reference to its presently preferred embodiment, it will be understood by one of ordinary skill in the art that various modifications can be made without departing from the spirit and the scope of the invention, as set forth in the appended claims.
