Abstract

PURPOSE: To increase the number of parked bicycle by releasing the wedge of a handle fixing part, releasing meshing of a connecting rod with a fixing tool, making a handle turnable by 90deg. in parallel to the ground and by fixing the handle by a lift of the fixing tool by means of a spring inside of the handle fixing part. CONSTITUTION: Meshing of the top part 7a of a connecting rod 7 with a handle 6 is released and the handle makes horizontal turn clockwise or counterclockwise by being slightly pushed by releasing the fixing pin 5 of a handle fixing part A, demounting a wedge 4 and slightly pushing a handle fixing tool 6 slightly downward. Thereby, the handle becomes turnable by 90deg. in parallel to the ground. Furthermore, the handle is so constituted as becoming fixable as it is by a lift of the handle fixing tool 6 by means of a spring 8 mounted inside of the handle fixing part A. Namely, since the top part 7a of the connecting rod 7 and the handle part are placed in mutual rectangular fitting, mutual meshing may be achieved again by turning thereof by 90deg. Therefore, a bicycle parking place area can be reduced by making the handle capable of turning by 90deg. in parallel to the ground.

Description

Detailed Description of the Invention

[0001]

[Industrial field of application] This relates to effective utilization of bicycle parking lots (increasing the number of bicycles parked) by reducing the bicycle parking capacity.

[0002]

2. Description of the Related Art Illegal bicycle parking in front of a station is out of the question, and in parking by a manager, the steering wheel and the front wheel are tilted 45 degrees to the right or left and aligned.

[0003]

It is sufficient if a bicycle parking lot can be newly provided or widened, but there are cases in which the bicycle cannot be used frequently because it is far from the destination. It is desirable to further increase the number of bicycles in the current bicycle parking space, and for that purpose space-saving bicycles are required. The following structures are obstacles to space saving in current bicycles. 1) About the steering wheel Since the steering wheel extends in the width direction of the vehicle body, it cannot hit the steering wheel of the adjacent bicycle or the front cage and reduce the bicycle parking space. 2) About the front basket Since it extends in the width direction, the handle of the adjacent bicycle hits and the bicycle parking space cannot be reduced. 3) Pedal Since the pedal faces the outside, it may collide with the pedal of the adjacent bicycle or the leg of the person trying to park the bicycle, disturbing the parking line and reducing the parking space. Can not. 4) Tilt of the front wheel When parking the bicycle, the front wheel usually leans to the right or left. Therefore, when carrying in and out, hold the handle and the vicinity of the saddle. When putting in and out at a place where the bicycles are densely packed, it is attempted to put the person in a narrow space with an adjacent bicycle and perform the above method, but it is difficult because the handle, the pedal, and the front basket collide with each other. Inevitably, the bicycle parking space cannot be reduced to provide an appropriate distance between bicycles.

Means for Solving the Problems The present invention has been achieved as a result of intensive research to solve the above problems, that is, the present invention provides a bicycle parking space without changing the basic structure and basic performance of a conventional bicycle. For bicycles that can be made smaller: 1) Remove the wedge of the handle fixing part A (the part that combines the wedge, fixing device, spring and fixing pin) and remove the meshing between the top of the connecting rod and the fixing device The handle can be rotated 90 degrees in the direction parallel to the ground, and the handle can be fixed as it is by lifting the fixture by the spring provided inside the handle fixing part. 2) At the connecting part B between the bicycle underframe and the handle support rod. It has a structure that rotates 90 degrees in the vertical direction to the ground by pulling out the attached fixing pin. 3) Two cranks connected to the pedal are overlapped and connected, and the hinge rotates 180 degrees. Ability structure and 4) articulation space available bicycle has a structure which can fix the front wheels in the insertion of the fixing pin aperture tube C which is provided adjacent to the B.

To explain the background of the present invention, bicycles are simple and space-saving simple vehicles, but in the current situation in front of stations or in supermarkets, the number of bicycles far exceeds the capacity of bicycle parking spaces. It is flooded. There are places where bicycle parking lots are built and organized by managers, but the number of bicycles is increasing and bicycles that can not fit in the bicycle parking lot are left on the road, which obstructs passage. see. In addition, it is difficult for bicycles to be put in and taken out at a crowded bicycle parking lot because it is difficult to collide with an adjacent bicycle. Therefore, the person who uses the bicycle parking lot has a wider space between the bicycle and the adjacent bicycle from the beginning in consideration of the time of putting out the bicycle.

The present invention will be described with reference to the drawings. As shown in the structure of FIGS. 1 and 2 (the stand is omitted from the figure for convenience), a general bicycle has a handlebar, a front cage, and a pedal that extend in the width direction of the vehicle body. Further, when the bicycle is parked, the front wheels are inclined to the left or right as shown in FIG. INDUSTRIAL APPLICABILITY The present invention does not impair the basic performance (running, stopping, bending, carrying) and safety and durability required for a bicycle, and handles, pedals,
The front cage and the fixed parts of the front wheels have been improved so that the owner can operate them easily and reliably when parked or riding.

The handle is described as follows: 1) The handle can be rotated 90 degrees in parallel with the ground to reduce the number of parking spaces. (Refer to FIGS. 6 to 17) FIG. 6 is a side view in which the handle of the bicycle of the present invention is improved so as to be able to rotate 90 degrees in parallel with the ground, and FIG. 7 is a plan view. The mechanism for horizontally rotating the handle part on the ground will be described with reference to a schematic diagram (the handle is omitted for the sake of simplicity), FIG. 10 shows a normal use state, and FIG. Remove the (shaded part) 4. FIG.
2 is the top 7 of the connecting rod 7 when the handle fixture is pushed down lightly.
The handle a is disengaged from the handle a, and the handle that is lightly pressed rotates horizontally to the right or left. FIG.
In the above, since the top portion of the connecting rod and the handle portion 1b are fitted in a quadrangular shape, when they are rotated by 90 degrees, the meshing will be made again. In FIG. 14, when the hand is released, the handle fixing tool is lifted up and fixed as it is.

2) The number of parking places is reduced by constructing the handle so that it can rotate 90 degrees perpendicular to the ground. (See FIGS. 8 and 9) FIG. 8 is a side view and FIG. 9 is a plan view.

FIG. 15 is a schematic view of the mechanism in which the handle can be moved up and down (the handle is removed for the sake of simplicity).

By removing the fixing pin 5a attached to the connecting portion B to the bicycle body frame and the handle support rod, it is rotated 90 degrees in the direction perpendicular to the ground. In FIG. 18, the fixing pin 5a is removed from the normal use state. In FIG. 19, the handle fixture 6 rotates.

3) Regarding the pedal P, in the arm (crank) connected to the pedal that rotates the gear, two cranks 9a and 9b are overlapped and connected by a hinge, and the structure is such that the hinge can be rotated by 180 degrees about a fulcrum. Reduce wheel space. (See FIGS. 20 to 27) When used as a bicycle, two arms (cranks) are overlapped and connected by a hinge. Fig. 20 Normal use condition (plan view) Fig. 21 〃 (front view) Fig. 22 〃 (left side view) Fig. 23 〃 (right side view) Next, at the time of parking with a hinge that can be rotated 180 degrees. Although the petal P faces outward, it enters the inside (180 degrees) when the bicycle is parked, and the bicycle parking capacity is reduced. (See FIGS. 21 and 25, and FIG. 23 and FIG. 27) FIG. 24 A state in which the hinge is rotated by 180 degrees (plan view) FIG. 25 〃 (front view) FIG. 26 〃 (left side view) FIG. 27 〃 (right side view) (Figure)

4) The fixing of the front wheels will be described. In the present invention, a part for fixing the front wheels in parallel with the vehicle body is attached. (Refer to FIGS. 28 and 29) When the fixing pin 5 of the opening pipe C provided adjacent to the connecting portion B between the bicycle frame 11 and the handle support rod 12 is inserted, the front wheel is fixed in parallel with the vehicle body. .

5) The front basket and the rear luggage carrier are narrow in the width direction of the bicycle and long in the length direction.

[0014]

[Operation] When the bicycle is parked, the handlebars, front cage and pedals have been improved so that they do not extend in the width direction of the vehicle body, and the front wheels can be fixed while facing in the straight ahead direction. Further space saving can be achieved when parking the bicycle by adding a device that makes the handle, pedal, and front cage that collide with each other closer to the saddle width or the bed width. By combining the above measures with fixing the front wheels, it is no longer necessary to enter and remove the bicycle in a narrow space between the bicycles. Inevitably, the space will be further saved, and the number of bicycles in the bicycle parking lot can be increased. Each device can be mechanically maintained while maintaining the required strength, so it does not impair the basic performance of the bicycle and is safe and durable.
