Description

1. Technical field

[0001] The invention relates to a roller skate with separate front and rear wheel holders with improved properties. 2. State of the art

[0002] Conventional roller skates can be divided into two types: roller skates with side-by-side wheels and inline skates. However, the wheel holder of a roller skate with side-by-side wheels cannot be mounted on the wheel holder of an inline skate, and vice versa. This requires further improvement. Object of the invention

[0003] An object of the invention is to provide a roller skate comprising a shoe body having a sole, a grooved rail arranged on the underside of the sole, and two through holes extending through the sides of the grooved rail; a front wheel assembly comprising a rear hole and two first wheels; a rear wheel assembly comprising a front hole and two second wheels; and a combination assembly comprising an axle rod with a thread, a clamping lever pivotably connected to the axle rod, and a nut fastened in one of the through holes; wherein the axle rod passes through the other through hole, the front hole, and the rear hole, and the thread is screwed into the nut; wherein the first wheels are arranged side by side or one behind the other, and the second wheels are arranged side by side or one behind the other.

[0004] The above-mentioned objectives, features and advantages of the invention are described in more detail below with reference to the accompanying drawings. Brief description of the drawings Fig. Figure 1 shows a perspective view of the roller skate according to a first embodiment of the present invention; Fig. Figure 2 shows an exploded view of the roller skate; Fig. Figure 3 shows a longitudinal section of the roller skate; Fig. Figure 4 shows a perspective view of the roller skate according to a second embodiment of the present invention; Fig. Figure 5 shows a perspective view of the roller skate according to a third embodiment of the present invention; and Fig. Figure 6 shows a perspective view of the roller skate according to a fourth embodiment of the present invention. Ways to implement the invention

[0005] With reference to the Fig. 1, Fig. 2 to Fig. 3. According to the first embodiment of the present invention, the roller skate 1 comprises the following: a shoe body 10, which has a shoe sole 11, a groove 12 arranged on the underside of the shoe sole 11 and through holes 13 extending through two sides of the groove 12; a front wheel assembly 20, which comprises a front wheel holder 21, a rear hole 22 arranged at the rear end of the front wheel holder 21 and two wheels 23 arranged side by side; a rear wheel assembly 30, which comprises a rear wheel holder 31, a front hole 32 arranged at the front end of the rear wheel holder 31 and two wheels 33 arranged one behind the other;and a combination assembly 40 comprising: a clamping lever 41 having two holes 410 on its cam side, an axle rod 42 having a hole 420 at one end and a thread 421 at the other end, a pivot axis 43 passing through the holes 410, 420, so that the clamping lever 41 and the axle rod 42 can be rotated together or the clamping lever 41 can be rotated about the axle rod 42, a washer 44 arranged on the axle rod 42 near the hole 420 and a nut 45 fastened in the through hole 13 away from the clamping lever 41.

[0006] During assembly, the axle rod 42 is passed through the through hole 13 located near the clamping lever 41, the front hole 32, the rear hole 22, and the through hole 13 furthest from the clamping lever 41. The axle rod 42 is then rotated clockwise, thereby tightening the threaded section 421 with the nut 45. The washer 44 is clamped between the outer surface of the hole 420 and the through hole 13 located near the clamping lever 41, thus assembling the front roller assembly 20 and the rear roller assembly 30. Finally, the clamping lever 41 is rotated until it makes contact with the groove 12.

[0007] To disassemble, the clamping lever 41 is turned in one direction so that it releases from the groove 12. The axle rod 42 is then turned counterclockwise to loosen the thread 421 from the nut 45. The axle rod 42 is then pulled out, removing it from the rear hole 22, the front hole 32, and the through hole 13 located near the clamping lever 41. This separates the front roller assembly 20 and the rear roller assembly 30.

[0008] The clamping lever 41 and the axle rod 42 are the main components of a quick-release fastener.

[0009] It will be on Fig. 4 Reference is made to the roller skate 1 according to the second embodiment of the present invention, which is characterized in that the two front wheels are arranged one behind the other as wheels 33 and the two rear wheels are arranged side by side as wheels 23.

[0010] It will be on Fig. Reference is made to Section 5. The roller skate 1 according to the third embodiment of the present invention is characterized in that all four wheels are wheels 23 arranged next to each other.

[0011] It will be on Fig. Reference is made to Section 6. The roller skate 1 according to the fourth embodiment of the present invention is characterized in that all four wheels are arranged one behind the other.

[0012] The present invention is suitable for roller skates, including ice skates and figure skates, provided that these have separate front and rear wheel holders.

[0013] Despite the description of the invention by reference to preferred embodiments, it will be obvious to those skilled in the art that modifications within the spirit and scope of the following attached claims can be made to the invention.
