Description

Technical area

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

[0002] Roller skates primarily utilize the wheels on the soles to allow people to glide quickly across the ground. Existing roller skates mainly include roller skates with two rows of wheels, roller skates with one row of wheels, and skates with blades. Roller skates with corresponding functions are used depending on the venue, environment, and purpose. In existing roller skates, whether they are roller skates with two rows of wheels, roller skates with one row of wheels, or skates with blades, the chassis is mostly fixed to the sole by screws and other fasteners. When the chassis needs to be replaced or maintained, additional tools are required, and the process is relatively complicated.Although some variants allow partial disassembly and assembly, their structure is too complicated or the locking mechanism is not stable enough, so that sliding safety and the advantages for replacement and maintenance cannot be taken into account at the same time.

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

[0004] The object of the invention is to provide a roller skate that can be easily and quickly assembled and disassembled without additional tools and allows exchange between different types of roller skates.

[0005] The object is achieved by the roller skate of the invention, which comprises: a shoe body having an upper and a sole, the sole defining a length direction and being provided with two pins spaced apart from each other in the length direction; a chassis having a first groove and a second groove, one end of the first groove and one end of the second groove being open to the surface of the chassis, the wall of the first groove forming a bottom wall and a blocking portion, and the blocking portion extending a distance in the length direction; a locking mechanism movably arranged on the chassis and releasably projecting into the second groove;and a sliding member arranged on the chassis, wherein the two pins are inserted into the first groove and the second groove, wherein one of the pins is limited by the blocking portion in a blocking direction, the blocking direction being the direction from the chassis to the sole, and wherein the other pin is limited by the locking mechanism in the blocking direction; Short description of the drawings Fig. 1 is a perspective view of an embodiment of the invention, Fig. 2 is an exploded view of an embodiment of the invention, Fig. 3 is a further exploded view of an embodiment of the invention, Fig. 4 is a sectional view of an embodiment of the invention, Fig. 5 is an enlarged view according to Fig. 4, Fig. 6 and Fig. 7 are illustrations of the operation of the embodiment of the invention, Fig. 8 and Fig. 9 are illustrations of the other sliding structure of the invention. Ways to implement the invention

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

[0007] Fig. Figures 1 to 7 show an embodiment of the invention. The roller skate 1 of the invention comprises a shoe body 10, a chassis 20, a locking mechanism 30, and a sliding element 40.

[0008] The shoe body 10 has an upper 11 and a sole 12. The sole 12 defines a length direction D1 and is provided with two pins 121 that are spaced apart from each other in the length direction D1. The chassis 20 has a first groove 21 and a second groove 22. One end of the first groove 21 and one end of the second groove 22 are open to the surface of the chassis 20. The wall of the first groove 21 forms a bottom wall 211 and a blocking portion 212. The blocking portion 212 extends a distance in the length direction D1. The locking mechanism 30 is movably arranged on the chassis 20 and releasably projects into the second groove 22. The sliding member 40 is arranged on the chassis 20. In the present embodiment, the sliding member 40 is one row of rollers, but the sliding member 40 may also have two rows of rollers ( Fig. 8) or a runner ( Fig.9). The two pins 121 are inserted into the first groove 21 and the second groove 22. One of the pins 121 is limited by the locking portion 212 in a locking direction D2. The locking direction D2 is the direction from the chassis 20 to the sole 12. The other pin 121 is limited by the locking mechanism 30 in the locking direction D2. Therefore, the chassis 20 can be easily and quickly assembled and disassembled without additional tools, and exchange between different types of roller skates is possible quickly and easily.

[0009] Preferably, the sole 12 further includes a blocking shoulder 122. The chassis 20 further includes a limiting shoulder 23. The blocking shoulder 122 and the limiting shoulder 23 mutually block each other in the length direction D1, thereby improving stability. The locking mechanism 30 extends between a pin 121 and the blocking shoulder 122. The blocking shoulder 122 covers part of the second groove 22 to provide reliable locking and support.

[0010] In the present embodiment, the first groove 21 is an L-shaped groove, which enhances the locking effect of the pin 121. The second groove 22 is a straight longitudinal groove 24, which is advantageous for inserting the pin 121 into the second groove 22. The sole 12 also has at least one locking projection 123 projecting toward the chassis 20. The chassis 20 also has at least one limiting projection 24 provided on the blocking portion 212. The at least one limiting projection 24 blocks the at least one blocking projection 123 in the length direction D1, thereby increasing the locking strength and effect between the chassis 20 and the sole 12. The at least one limiting projection 24 connects over the first groove 21 and can reliably limit the pin 121.

[0011] Furthermore, the shoe body 11 has a toe cap 111 and a locking disc 112. The toe cap 111 is adjustably clamped between the locking disc 112 and the sole 12. The sole 12 is further provided with a snap mechanism 125 that can be operated from outside the shoe body 10. The toe cap 111 is provided with a row of teeth 113. The snap mechanism 125 has at least one tooth 126. The at least one tooth 126 releasably engages the row of teeth 113. Specifically, the locking mechanism 30 includes an operating button 31, a rod 32, an elastic element 33, and a stopper 34. The stopper 34 and the rod 32 are connected to one another and movably arranged in the chassis 20. The elastic element 33 is located between the stopper 34 and the chassis 20, allowing the stopper 34 to be automatically reset. The stopper 34 projects into the second groove 22 and stops the pin 121 in the locking direction D2.The control knob 31 is connected to the rod 32 and is located outside the chassis 20. By operating the control knob 31, the user can freely adjust the position of the toe cap 111 to suit different foot shapes as needed.
