Description

Technical area

[0001] The invention relates to a sports device, in particular a roller skate. State of the art

[0002] Roller skating is a popular and widespread sport and leisure activity. Roller skating requires wearing roller skates. In conventional roller skates, the cuffs are usually freely rotatable and connected to the shoe body, and laces are used to tighten and fix the cuffs. However, when wearing roller skates, the laces must first be loosened so that the cuffs can be rotated outward to form a larger entrance for the foot. After that, the laces must be tightened again to ensure the roller skates fit snugly on the foot. However, if the laces are not tightened, the cuffs cannot be positioned and will swing uncontrollably. For this reason, conventional roller skates are not smooth, lightweight, practical, or convenient to put on and take off, and the structure is relatively complicated.

[0003] Therefore, it is necessary to provide a novel and advanced roller skate to solve the above problems. Object of the invention

[0004] The object of the invention is to provide a roller skate whose protective cuff can be adjusted and positioned by turning, whereby the structure is simple and no additional laces are required.

[0005] This object is achieved by the roller skate of the invention, which comprises: a shoe comprising a shoe body and a protective cuff, wherein the shoe body has two first connecting portions, wherein the two first connecting portions are located on two opposite sides of the shoe body, wherein at least one of the first connecting portions is provided with a first non-circular structure, wherein the protective cuff has two second connecting portions, and wherein at least one of the second connecting portions is provided with a second non-circular structure; a walking part arranged on the underside of the shoe body; and two joint mechanisms, each including a joint element, wherein the joint element is inserted into one of the first connecting portions and one of the second connecting portions, wherein the joint element of at least one of the joint mechanisms is provided with a non-circular locking structure,and wherein the non-circular locking structure can be moved between a locking position and an unlocking position, wherein, when the non-circular locking structure is in the locking position, the non-circular locking structure is simultaneously connected to the first non-circular structure and the second non-circular structure without relative rotation, so that the protective sleeve is positioned and cannot rotate relative to the shoe body, and when the non-circular locking structure is in the unlocking position, the non-circular locking structure disengages from at least one of the first non-circular structure and the second non-circular structure, so that the protective sleeve is released and can rotate relative to the shoe body.

Ways to implement the invention

[0006] The following embodiments are merely illustrative of possible implementations of the invention and are not intended to limit the scope of the invention.

[0007] Fig. Figures 1 to 6 show an embodiment of the invention. The roller skate 1 of the invention comprises a shoe 10, a running part 20, and two joint mechanisms 30.

[0008] The shoe 10 comprises a shoe body 11 and a protective sleeve 12. The shoe body 11 has two first connecting sections 111. The two first connecting sections 111 are located on two opposite sides of the shoe body 11. At least one of the first connecting sections 111 is provided with a first non-circular structure 112. The protective sleeve 12 has two second connecting sections 121. At least one of the second connecting sections 121 is provided with a second non-circular structure 122. The running part 20 is arranged on the underside of the shoe body 10. The running part 20 is, for example, a row of rollers, two rows of rollers, or a runner. Each joint mechanism 30 includes a joint element 31. The joint element 31 is inserted into one of the first connecting sections 111 and one of the second connecting sections 121.The joint element 31 of at least one of the joint mechanisms 30 is provided with a non-circular locking structure 311. The non-circular locking structure 311 can be moved between a locking position (. Fig. 3) and an unlocking position ( Fig.4). When the non-circular locking structure 311 is in the locking position, the non-circular locking structure 311 is simultaneously connected to the first non-circular structure 112 and the second non-circular structure 122 without relative rotation, so that the protective sleeve 12 is positioned and cannot rotate relative to the shoe body 11. When the non-circular locking structure 311 is in the unlocking position, the non-circular locking structure 311 detaches from at least one of the first non-circular structure 112 and the second non-circular structure 122, so that the protective sleeve 12 is released and can rotate relative to the shoe body 11. As a result, the protective sleeve 12 can be easily removed by actuating it (e.g.pressing) of the joint mechanism 30, whereby putting on and taking off the roller skate 1 is extremely smooth, easy, convenient and comfortable (especially for children), and the structure is simple and no additional shoelace is required.

[0009] The non-circular locking structure 311 can be inserted into the first non-circular structure 112 and the second non-circular structure 122. For example, the non-circular locking structure 311 can be inserted into the first non-circular structure 112 and the second non-circular structure 122, or the first non-circular structure and the second non-circular structure can be inserted into the non-circular locking structure. In particular, the first non-circular structure 112 is a first non-circular hole and the second non-circular structure 122 is a second non-circular hole. The non-circular locking structure 311 is a non-circular piece 312. The first non-circular structure 112, the second non-circular structure 122, and the non-circular locking structure 311 can be polygonal structures (e.g.,triangular, square, pentagonal or other structures), whereby the protective sleeve 12 can be adjusted and positioned at multiple angles.

[0010] The articulated element 31 of at least one pivoting mechanism 30 also includes a working rod 313 and a block 314 connected to the working rod 313. The working rod 313 is inserted into the first non-circular structure 112 and the second non-circular structure 122. The block 314 forms the non-circular piece 312. The working rod 313 is provided with an outer flange 315 and a shoulder 316. The block 314 is placed onto the working rod 313 and confined between the outer flange 315 and the shoulder 316. In this way, the manufacture and assembly of the articulated element 31 can be carried out quickly and easily. By actuating the working rod 313, the non-circular locking structure 311 can be moved into the unlocking position.

[0011] Preferably, the first non-circular structure 112 further includes a non-circular recess 113. The block 314 also includes a non-circular flange 317 extending radially from the non-circular piece 312. When the non-circular locking structure 311 is in the locking position, the non-circular flange 317 engages the non-circular recess 113 without relative rotation, thereby increasing the connection strength and stability.

[0012] In this embodiment, the two first connecting portions 111 each have a first non-circular structure 112, the two second connecting portions 121 each have a second non-circular structure 122, and the joint elements 31 of the two joint mechanisms 30 each have a non-circular locking structure 311, thereby simultaneously providing the function of adjustable positioning of the protective sleeve 12 on the opposite sides of the shoe body 10 and also providing good structural strength. Preferably, an elastic element 40 is also provided between the joint element 31 and the shoe body 10. The elastic element 40 presses against the joint element 31, so that the non-circular locking structure 311 can automatically return to the locking position, enabling convenient and reliable positioning.The two first connecting portions 111 are each further provided with an annular protrusion 114, and the two second connecting portions 121 are each further provided with a groove 123. The annular protrusion 114 engages with the groove 123, so that the protective sleeve 12 does not deviate randomly and rotates stably, reducing the load on the pivot mechanism 30.

[0013] Preferably, the shoe body 11 further includes a chassis 115, a support member 116, and a threaded rod 117. The support member 116 is movably connected to the chassis 115 and has a toothed portion 118. The threaded rod 117 is rotatably inserted into the chassis 115 and engages the toothed portion 118. By rotating the threaded rod 117, the support member 116 can be moved, so that the size of the shoe body can be adjusted to fit feet of different sizes.

[0014] The invention thus relates to a roller skate comprising: a shoe (10) having a shoe body (11) and a protective sleeve (12), wherein the shoe body (11) has two first connecting portions (111), wherein the two first connecting portions (111) are located on two opposite sides of the shoe body (11), wherein at least one of the first connecting portions (111) is provided with a first non-circular structure (112), wherein the protective sleeve (12) has two second connecting portions (121), and wherein at least one of the second connecting portions (121) is provided with a second non-circular structure (122); a running part (20) arranged on the underside of the shoe body (10); and two joint mechanisms (30), each including a joint element (31), wherein the joint element (31) is inserted into one of the first connecting portions (111) and one of the second connecting portions (121).wherein the joint element (31) of at least one of the joint mechanisms (30) is provided with a non-circular locking structure (311), and wherein the non-circular locking structure (311) can be moved between a locking position and an unlocking position, wherein, when the non-circular locking structure (311) is in the locking position, the non-circular locking structure (311) is simultaneously connected to the first non-circular structure (112) and the second non-circular structure (122) without relative rotation, so that the protective sleeve (12) is positioned and cannot rotate relative to the shoe body (11), and when the non-circular locking structure (311) is in the unlocking position, the non-circular locking structure (311) is released from at least one of the first non-circular structure (112) and the second non-circular structure (122),so that the protective sleeve (12) is released and can rotate relative to the shoe body (11).
