Description

Bicycle frame

The present invention relates to a bicycle stationary frame, which is used for technical improvement of the bicycle stationary frame.

When a bicycle is parked, the stationary frame (center column or side column) is usually lowered to support the ground so that the bicycle can remain parked stably. However, the stationary frame is often hit by external forces or pushed by others against the bicycle body, causing the stationary frame to swing upward and unable to support the bicycle, which can easily cause the bicycle to fall to the ground and be damaged.

Therefore, it is necessary to provide a novel and advanced bicycle frame to solve the above-mentioned problems.

The main purpose of the present invention is to provide a bicycle frame which can be locked after being placed under the bicycle frame to provide a stable fixed position.

To achieve the above-mentioned object, the present invention provides a bicycle frame, which comprises: a fixing seat, which is mounted on a bicycle frame, the fixing seat is provided with a locking portion, and the locking portion is provided with a locking hole; a leg, which is provided on the fixing seat and can swing relative to the fixing seat; and a locking mechanism, which comprises a control member, a linkage member and a locking member, the control member and the locking member are respectively provided on the leg, The linkage is connected between the control member and the locking member, and the control member can drive the linkage to link the locking member between a first position and a second position; wherein, when the locking member is located at the first position, the locking member is inserted into the locking hole so that the tripod cannot swing relative to the fixing seat; when the locking member is located at the second position, the locking member is disengaged from the locking hole so that the tripod can swing relative to the fixing seat.

The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The "one" or "at least one" preceding the terms mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of protection, which should be explained in advance.

Please refer to Figures 1 to 7, which show a first preferred embodiment of the present invention. The bicycle frame 1 of the present invention includes a fixing seat 10, a leg frame 20 and a locking mechanism 30.

The fixing seat 10 is mounted on a frame of a bicycle 2 and is provided with a locking portion 11, and the locking portion 11 is provided with a locking hole 12. The tripod 20 is provided on the fixing seat 10 and can swing relative to the fixing seat 10. The locking mechanism 30 includes a control member 31, a linking member 32 and a locking member 33. The control member 31 and the locking member 33 are respectively provided on the tripod 20, and the linking member 32 is connected between the control member 31 and the locking member 33. The control member 31 can drive the linking member 32 to link the locking member 33 between a first position and a second position. When the locking member 33 is located at the first position (as shown in FIGS. 1 and 3 ), the locking member 33 is inserted into the locking hole 12 so that the tripod 20 cannot swing relative to the fixing base 10 ; when the locking member 33 is located at the second position (as shown in FIG. 4 ), the locking member 33 is disengaged from the locking hole 12 so that the tripod 20 can swing relative to the fixing base 10 .

Thereby, the tripod 20 can be locked and positioned after being swung down, and will not be arbitrarily swung upward by external force, and the control member 31 can be controlled to be automatically unlocked.

The fixing base 10 is provided with at least one guide hole 351 for the locking member 33 to pass through, so that the locking member 33 can move relatively smoothly.

The linking member 32 is a deformable linking wire, and in other embodiments, it may also be a linking rod or other linking elements. The linking wire can be bent and deformed by its deformable characteristics, such as bending and extending along the structure of the tripod 20, so as to facilitate installation and operation. The tripod 20 is tubular and has a wire channel 21 formed therein. The linking member 32 at least partially passes into the wire channel 21. The linking member 32 includes a first coupling end 321 and a second coupling end 322. The first coupling end 321 is located on the outside of the tripod 20 to connect to the locking member 33, and the second coupling end 322 is connected to the control member 31. The linking wire can be hidden and stored in the tripod 20 to protect the linking wire from external force damage and provide an aesthetic effect.

The control member 31 can move between a third position (as shown in FIG. 1 and FIG. 3 ) and a fourth position (as shown in FIG. 4 ) relative to the tripod 20; wherein, when the control member 31 is located at the third position, the locking member 33 is located at the first position; and when the control member 31 is located at the fourth position, the locking member 33 is located at the second position. Specifically, the tripod 20 is provided with a long hole 22, and the long hole 22 is connected to the wire channel 21. The locking mechanism 30 further includes a coupling member 34, and the coupling member 34 can be movably provided in the long hole 22 relative to the long hole 22. A first end 341 of the coupling member 34 is coupled to an end of the linking member 32, and a second end 342 of the coupling member 34 is coupled to the control member 31. To further explain, the coupling member 34 is detachably mounted on the control member 31. During installation, the linking member 32 can be firstly connected to the connecting member 34, and then the connecting member 34 is passed through the long hole 22 and one end thereof is protruded and installed on the control member 31, so as to facilitate installation. The moving direction of the control member 31 can be guided by the long hole 22.

The locking mechanism 30 further includes a base 35 and an elastic member 36. The base 35 is disposed on the tripod 20. The locking member 33 can be movably disposed on the base 35 relative to the base 35. The outer periphery of the locking member 33 is provided with a radially protruding abutting portion 331. The elastic member 36 elastically abuts between the abutting portion 331 and the base 35. In this embodiment, the abutting portion 331 is a C buckle, and in other embodiments it can also be integrally formed on the locking member. In this embodiment, the leg 20 has a pivoting portion 23 and a bottom end portion 24 at two opposite sides. The leg 20 is pivoted to the fixing base 10 by the pivoting portion 23. The control member 31 is disposed at the bottom end portion 24. The control member 31 has a step portion 311. The elastic member 36 elastically abuts against the abutting portion 331 to keep the locking member 33 normally in the first position. In addition, the user can press the pedal 311 to drive the control member 31 to move from the third position to the fourth position (downward), and drive the locking member 33 to move from the first position to the second position, so as to achieve the purpose of unlocking, so that the tripod 20 can swing down relative to the fixing base 10, and after the foot releases the downward pressure on the pedal 311, the elastic member 36 can rebound against the locking member 33 to return to its original position. Therefore, unlocking is convenient.

The hinge 23 includes at least one ear 231. A locking piece 50 passes through the hinge 23 and the fixing base 10. The locking piece 50 defines an axis 3. The bracket 20 rotates relative to the fixing base 10 with the axis 3 as a rotation center. The structure is simple and easy to install.

The locking mechanism 30 further includes a seat body 37, which is disposed on the leg frame 20 (can be locked or welded), and the seat body 37 is provided with at least one through hole 371. The control member 31 can movably penetrate the at least one through hole 371, so that it can move smoothly and stably relative to the seat body 37.

The locking member 33 can move between the first position and the second position along an axis A. The locking portion 11 and the locking member 33 are arranged along the axis A. The locking portion 11 is a tilting plate transverse to the axis A. The locking member 33 can bounce against the locking portion 11. Therefore, during the process of swinging the tripod 20 up and down, the locking member 33 can reliably abut against the tilting plate. Specifically, when the tripod 20 is lowered (as shown in FIG. 5 ), the locking member 33 can be pressed against the tilting plate and gradually pressed downward toward the locking hole 12, so that when the locking member 33 is aligned with the locking hole 12, it can be pushed by the elastic member 36 and inserted into the locking hole 12 for positioning. Therefore, during the process of lowering the tripod 20, the locking member 33 can be automatically and smoothly inserted into the locking hole 12 for positioning without the need for the control member 31.

Please refer to Figures 8 to 9, which show a second preferred embodiment of the present invention. The locking member 33 can move between the first position and the second position along the axis A. The locking portion 11' and the locking member 33 are arranged along the axis A. The locking portion 11' is an arc-bent plate. The locking member 33 can spring against the locking portion 11'. Accordingly, the arc-bent plate provides a large area for the locking member 33 to abut against, so that the tripod 20 can remain against the locking portion 11' after being swung up, and during the process of the tripod 20 being swung down, the locking member 33 can be pressed down along the locking portion 11' until it is elastically reset and inserted into the locking hole 12.

Please refer to Figures 10 to 11, which show a third preferred embodiment of the present invention. The bicycle frame 1a is provided with two fixing seats 10a, and the leg 20a is provided with two pivoting parts 23a arranged at intervals. The two pivoting parts 23a are pivoted on the fixing seats 10a so that the leg 20a can swing relative to the two fixing seats 10a. The control member 31 and the locking member 33a are provided on the leg 20a. The locking member 33a can be selectively inserted into the locking hole 12 of one of the fixing seats 10a so that the leg 20a cannot swing relative to the two fixing seats 10a; the control member 31 can disengage the locking member 33a from the locking hole 12 through the linkage member 32.
