Abstract
Description
Technical field
[0001] The invention relates to a kick scooter, in particular a kick scooter whose handlebar can be removed without tools. State of the art
[0002] Conventional kick scooters are steered by turning the handlebars. The handlebars are typically clamped in place by a clamping block attached to them. This clamping block is usually secured to the handlebars with several screws and nuts. As a result, tools (such as Allen wrenches or screwdrivers) are required for assembly, disassembly, replacement, and maintenance, making these tasks extremely cumbersome and time-consuming. Furthermore, the need for tools makes assembly and disassembly awkward for the user. Storage is also complicated, and the packaging volume is large.
[0003] Therefore, it is necessary to provide a novel and advanced kick scooter to solve the aforementioned problems. Object of the invention
[0004] The object of the invention is to provide a kick scooter whose handlebar can be disassembled without tools. Operation is simple, quick and convenient, storage is simplified and packaging volume is reduced.
[0005] This objective is achieved by the kick scooter of the invention, which comprises: a main body having a footboard and at least two wheels, one of which is mounted on the footboard; a steering tube rotatably mounted on the main body and connected to the other of the at least two wheels, the steering tube having a mounting end facing away from the footboard; a handlebar; and a connecting assembly comprising a fastening part and a fastening element, the fastening part clamping the handlebar, the fastening element having a manual drive section and a connecting section connected to the manual drive section, the connecting section being passed through the fastening part and connected to the mounting end, and the connecting section being attached to or detached from the mounting end by actuating the manual drive section. Brief description of the drawings Fig. 1 a perspective view of the embodiment of the invention, Fig. 2 a partial exploded view of the embodiment of the invention, Fig. 3 a partial sectional view of the embodiment of the invention, Fig. 4 and Fig. 5. Illustrations of the movement of the embodiment of the invention, Fig. 6 an enlarged representation according to Fig. 5. Ways to implement the invention
[0006] The following embodiments serve only to illustrate possible implementations of the present invention and are not intended to limit the scope of protection of the present invention.
[0007] Figures 1 to 6 show an embodiment of the invention. The kick scooter 1 of the invention comprises a main body 10, a steering tube 13, a handlebar 14 and a connecting assembly 20.
[0008] The main body 10 has a footboard 11 and at least two wheels 12, one of which is mounted on the footboard 11. The steering tube 13 is rotatably mounted on the main body 10 and connected to the other of the at least two wheels 12. The steering tube 13 has a mounting end 131 facing away from the footboard 11. The connecting assembly 20 includes a fastening part 21 and a fastening element 22. The fastening part 21 clamps the steering rod 14. The fastening element 22 has a manual drive section 221 and a connecting section 222 connected to the manual drive section 221. The connecting section 222 passes through the fastening part 21 and connects to the mounting end 131. By actuating the manual drive section 221, the connecting section 222 is attached to or detached from the mounting end 131. In this way, the steering rod can be assembled and disassembled without disassembly tools.Operation is simple, quick and convenient, storage is made easier and packaging volume is reduced.
[0009] The mounting end 131 has a threaded element 23, and the connecting section 222 has a threaded section 24. The threaded element 23 or the threaded section 24 forms an internal thread, and the other forms an external thread, with the internal and external threads being screwed together. More precisely, the threaded element 23 is a fastening nut with the internal thread, and the threaded section 24 is a threaded rod with the external thread. In this embodiment, the manual drive section 221 has a rotary knob 223. The user can tighten or loosen the connecting section 222 by simply turning the rotary knob 223, without the need for disassembly tools.
[0010] Preferably, the fastening part 21 has a recess 211, and the rotary knob 223 has a base 224 and a handle 225 extending from the base 224. When the connecting section 222 is attached to the mounting end 131, the base 224 is received in the recess 211, thereby reducing or preventing excessive protrusion of the rotary knob 223 and preventing damage and / or loosening by external forces. The fastening part 21 also has a retaining nut 212 to which the threaded section 24 is screwed, so that the fastening element 22 remains in a confined position during operation or during incomplete disassembly and is prevented from falling off or being lost, thus improving ease of use.
[0011] The fastening part 21 also has an upper fastening block 213 and a lower fastening block 214. The steering rod 14 is clamped between the upper fastening block 213 and the lower fastening block 214. The connecting section 222 runs through the upper fastening block 213 and the lower fastening block 214. The retaining nut 212 is located in the lower fastening block 214.
[0012] More precisely, the mounting end 131 has a first mounting structure 132, and the fastening part 21 has a second connecting structure 215. The first and second connecting structures 132 and 215 are non-circular and are inserted into one another in a rotationally fixed manner, thus preventing relative rotation during operation. In this embodiment, the first connecting structure 132 is a non-circular section, and the second connecting structure 215 is a non-circular hole. Both can have polygonal, elliptical, or other non-circular shapes to ensure the alignment and controllability of the steering rod.
[0013] The connecting assembly 20 further includes at least one screw 30 and at least one lock nut 31. The at least one screw 30 passes through the steering rod 14 and the fastening part 21. The at least one lock nut 31 is screwed onto the at least one screw 30 to fasten the steering rod 14 to the fastening part 21. This ensures that the steering rod 14 does not rotate freely relative to the fastening part.
