Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a handle fixing device, and more particularly to a handle fixing device for a bicycle or a kick board.

[0002]

[Prior art]

 FIG. 1 shows a three-dimensional view of a conventional handle fixing device for a kick board or a bicycle, in which a joint pipe 11 is mainly welded to the upper end of a pre-expandable / contractible pipe 10 of a kick board, and is located on both outer walls of both ends of the joint pipe 11. The holes 12 are made to penetrate, and the two handle bars 20 are also provided with localization holes 22 in the inner insertion step 21. The handle bars 22 are each provided with an elastic bow 24 having a localization convex body 23. The protrusion 23 is projected from the positioning hole 22 of the handle bar.

[0003] Then, the localization convex body 23 of the insertion step 21 of the two handles 20 is pushed flat, and is inserted laterally from both ends of the joint pipe 11, and the localization convex body 23 is inserted into the localization hole 12 of the joint pipe 11. Adjustment is made so as to correspond, and the elastic convex body 23 projects from the localization hole 12 to localize. The two handles are supported by this fixing force, and the kick board is grasped and operated. Further, after the stereotaxic body 23 is made to protrude, the two handle bars 20 are pulled out, and the stoppers 26 at the ends of the two handles are stopped by the elastic ropes 25 connected to the two handle bars 20, and the two handle bars are stopped. Handle rod 20 is hung down on both sides of the insertion tube 11.

[0004] In the above handle fixing device, the connection between the handle bar and the insertion tube is based solely on the protruding positioning member projecting from the fitting positioning. The kickboard operation is unstable because of the rattling gap. In addition, when the two handle bars are removed, they should still be connected to the insertion tube, and should be further provided with a stopper 26 on the outside of the handle to provide a connection of the elastic rope. Not a simple design.

[0005]

[Problems to be solved by the invention]

 The present invention has been made to solve such a problem, and is applied to a bicycle or a kick board, and a handle fixing device which can be stably gripped safely by sandwiching the handle, and which can be easily folded and unfolded. The purpose is to provide.

[0006]

[Means for Solving the Problems]

 The handle fixing device of the present invention is mainly a T-shaped joint integrally formed, and an insertion neck extending in the vertical direction from the middle of the T-shaped joint downward is provided with a recessed inner groove. The front and rear fronts of the T-shaped joint, which can be inserted into the upper end of the front pipe of the kick board before and after expansion and contraction, and are compounded so as to be screwed and pressed, are each a long piece. There is a long sliding hole with a fisheye hole and an enlarged round hole at the handle insertion end. A bolt with an enlarged neck has a fisheye hole of a long piece and the length of the handle. After penetrating the sliding hole and the other piece on the other side, penetrate a spring and a washer in advance at the end, further tighten with a nut, and pass the tightening piece between the two pieces with a screw rod with a fast-disassembling pattern. Tighten in the longitudinal neck at the center , Characterized in that to complete the combination.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. An embodiment in which the present invention is applied to a kick board will be described with reference to the drawings to explain the structure of the present invention and the effects and advantages that can be achieved. However, the present invention can also be applied to a bicycle handle.

FIG. 2 shows a three-dimensional exploded view of this embodiment, and FIG. 3 shows a combination diagram of this embodiment. It is mainly combined by the joint 30, the prematurely disassembled handle 40, the tension piece 50, the nut set 60 and the like.

The joint 30 is an integrally formed T-shaped joint, and an insertion neck 31 extending vertically from the middle of the T-shaped joint has a stereotactic guide groove 32 formed in a recess. After being inserted into the upper end of the pre-expansion tube 10 of the board, it is guided and compressed by screws 11. The upper part of the T-shaped joint is formed into a long piece 33 at the front and rear sides, and a suitable space is formed between the two opposite pieces so that the handle bar 70 can be inserted. The fisheye hole of one piece 33 is a fisheye hole 34 ′ having an enlarged inner hole, and a tightening piece 50 is provided between the two pieces by a screw rod 41 of a fast-disassembling handle 40. After passing through, insert in the central longitudinal direction and tighten it into the screw hole in the neck 31 to complete the combination.

A long sliding hole 72 having a round hole 73 expanded outward is provided at the insertion end 71 of each of the handle bars 70, a screw pattern 61 is provided at the last stage, and a fitting having an increased outer diameter other than the head is provided. First, the bolt 60 having the neck portion 62 penetrates the fisheye hole 34 ′ in which the inner hole of the piece 33 is enlarged, and then the long slip hole 72 of the handle 70, and the fisheye of the piece 33 on the other side. After penetrating the hole 34, a spring 63 and a washer 64 are preliminarily penetrated at the ends thereof, and further tightened with a nut 65, and the fitting neck 62 of the bolt is fitted into the enlarged inner hole of the fisheye hole 34 'and combined. To complete.

FIGS. 4 and 5 are front and top views of the combined cross section of the present embodiment. The handle bar 70 is rotated laterally around the bolt 60 as a fulcrum, When the enlarged round hole 73 corresponds to the bolt 60, the spring 63 is pushed from the end of the bolt 60, and the enlarged neck 62 is fitted into the enlarged round hole 73. When depressed, the inserts 71 of both handlebars 70 are firmly secured by the tensioning pieces 50 to provide a secure grip.

Conversely, as shown by the arrow in FIG. 5, when the quick disassembling handle 40 is pulled up, the tightening piece 50 is loosened, and the thumb 60 pushes the bolt 60 from the nut at the end of the bolt, the enlarged neck 62 of the bolt 60 is moved. The handle bar 70 can be pushed out of the enlarged round hole 73 and folded under the drawer.

[0013] As in the structure of the above-described embodiment, the handle fixing device of the present invention is such that the tightening piece is firmly clamped to the handle bar by the quick disassembly handle, and the enlarged neck portion of the bolt penetrating the handle bar is handled by the handle. Fitted into the enlarged round hole opposite the bar, the interaction of these two fixing forces ensures a sturdy connection of the handlebars, which can be used for kickboard or bicycle handles, securely gripping the handle securely Provide an operational kickboard or bicycle.
