Description

The present invention relates to a bicycle folding device and a positioning structure thereof, and more particularly, to a bicycle folding device having a quick detaching structure and a positioning structure.

In the conventional folding bicycle, a folding device having a quick removal structure is attached to an appropriate part such as a frame, and the frame is expanded and folded by quickly assembling and separating.

Generally, since the conventional quick removal structure is provided on the side of the folding device, the volume of the folding device is very large. Although the folding device was an important part for the folding bicycle, the size was very large and the appearance was not preferable.

Furthermore, since the conventional folding bicycle is not provided with a positioning structure when it is folded and carried or unfolded, the frame may move freely. Furthermore, the folding device may suddenly open and the rider's safety may be jeopardized by the impact force received when riding a bicycle and passing through a non-planar area with the quick-release structure alone.

The present invention has been made in view of the above points. The bicycle folding device disclosed by the present inventors (for example, Patent Document 1) is combined with a positioning structure, and the frame is folded by the folding device and carried. Since the positioning can be maintained even after being deployed, there is no possibility that the frame may move or be displaced by an external force.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.

Please refer to FIG. 1 and FIG. As shown in FIGS. 1 and 2, a bicycle folding apparatus according to an embodiment of the present invention includes a first folding unit 1 and a second folding unit 2. The first folding part 1 is provided with a first pivoting part 11 on the side part, a quick removal receiving seat 12 is provided on the inner periphery, and a quick removal structure 13 is connected (shown in FIG. 3). .

The second folding part 2 is provided with a quick removal pressing hole 21 so as to correspond to the quick removal seat 12 of the first folding part 1, and the second pivoting part 22 provided on the side part is provided. The first folding part 1 of the first folding part 1 is pivotally attached to be movable.

The positioning structure 3 includes a first fold 1, a channel 14 and a second fold 2. A channel 14 is provided in the pivot part 11 of the first folding part 1. The channel 14 has a sealed end at one end, a hole 140 at the other end, and at least one through-hole 141. The positioning control rod 16 to be inserted into the channel 14 is provided with a spring 15 at one end, the other end is exposed from the hole 140 of the channel 14, and the corresponding recess is formed at a position corresponding to the through hole 141 of the channel 14. 160 is provided. Opposing slopes 161 are provided on both sides of the inner periphery of the corresponding recess 160.

The positioning body 17 is inserted into the through hole 141 of the channel 14 so that the positioning body 17 is always in contact with a portion other than the corresponding recess 160 of the positioning control rod 16.

Positioning holes 31 are provided at positions where the second folding part 2 of the second folding part 2 is subjected to predetermined folding and unfolding. The positioning body 17 provided in the first folding part 1 is fitted into the positioning hole 31 so as to correspond thereto.

Please refer to FIG. FIG. 4 is a cross-sectional view illustrating a positioning structure according to an embodiment of the present invention.

The first folding part 1 and the second folding part 2 according to an embodiment of the present invention are coupled to a place where the frame 4 is folded, and the quick removal structure 13 is loosened or tightened to expand the frame. (Shown in FIG. 5) or folded (shown in FIG. 6).

The bicycle folding apparatus and its positioning structure according to this embodiment can be positioned safely and easily when the folding apparatus is folded or unfolded using the positioning structure 3.

The positioning control rod 16 enters inside when pressed, and when the corresponding concave portion 160 moves to a position below the positioning body 17, the positioning body 17 completely sinks into the corresponding concave portion 160, and the second folding portion 2 and the positioning control rod 16 are moved. Positioning is released. In this way, the frame can be folded or unfolded by using the second folding unit 2 (shown in FIG. 7).

When the second folding portion 2 is folded to a predetermined positioning position, the force applied to the positioning control rod 16 is lost, and the positioning body 17 is pushed by the opposing inclined surface 161 of the positioning control rod 16 by being pushed by the spring 15 and returning. Then, it floats from the corresponding recess 160 of the positioning control rod 16 and is fitted into the positioning hole 31 on the second folding part 2 for positioning.

Please refer to FIG. As shown in FIG. 8, the positioning structure 3 according to another embodiment of the present invention includes a channel 14 in the first pivot part 11 of the first folding part 1. The channel 14 has a sealed end at one end and a hole 140 at the other end. The channel 14 is provided with at least one through hole 141. The positioning control rod 16 and the spring 15 are accommodated in the channel 14. The positioning control rod 16 is exposed from a hole 140 provided at the other end of the channel 14 after the spring 15 is fitted on one end. As shown in FIG. 9, when the positioning control rod 16 is pulled outward in the direction of the arrow and the corresponding recess 160 moves below the positioning body 17, the positioning body 17 completely sinks into the corresponding recess 160, and the second The positioning with the folding unit 2 is released. Thereby, the frame can be folded or unfolded as necessary.

When the second folding unit 2 is folded to a predetermined positioning position, the force applied to the positioning control rod 16 is eliminated. As a result, when the positioning control rod 16 is pushed in the opposite direction and restored, and the positioning body 17 is pushed by the opposing slope 161 and lifts up from the corresponding recess 160 of the positioning control rod 16, the positioning hole on the second folding portion 2 is placed. Positioning is performed by fitting to 31.
