Technical Field

The invention relates to a double-foot support and a bicycle, and belongs to the field of bicycles.

Background

Most of the existing bicycles are supported by single feet, but the supporting force of the single-foot support is not enough, so that the problem that the bicycle falls down is often caused.

Some bicycles can adopt both feet to support, but the fixed part that current both feet supported can produce with the bicycle chain and interfere, especially have the bicycle of variable speed function, and when the variable speed, the chain that is located the below can be raised to touch both feet and support, light then take place the abnormal sound, heavy then damage the bicycle.

Accordingly, there is a need for an improved dual foot support and bicycle to solve the above problems.

In order to achieve the above object, the present invention provides a biped support, which is arranged on a bicycle to support the bicycle, the biped support includes a fixed block, a pivot block, and two support legs fixed on two sides of the pivot block, the upper end of the pivot block is pivotally connected to the lower end of the fixed block, the biped support has a first state where the support legs support the ground and a second state where the support legs are raised, and the height of the pivot block when the biped support is in the second state is higher than the height of the pivot block when the biped support is in the first state.

As a further improvement of the invention, the fixed block is n-shaped, the opening of the fixed block faces the pivoting block, the pivoting block is u-shaped, and the opening of the pivoting block faces the fixed block.

As a further improvement of the invention, the double-foot support further comprises a connecting spring, and two ends of the connecting spring are respectively connected with the fixed block and the pivoting block.

As a further improvement of the invention, a first beam is arranged in the fixed block, a second beam is arranged in the pivoting block, and two ends of the connecting spring are respectively connected with the first beam and the second beam.

As a further improvement of the invention, the bottom parts of the two supporting feet are provided with cushion blocks for supporting on the ground.

As a further improvement of the present invention, the bipedal support further comprises at least one foot plate connected to the support foot, the foot plate supporting the ground when the bipedal support is in the first state.

As a further improvement of the present invention, a first limiting portion is disposed on the fixing block, a protruding portion is disposed at a top end of the pivoting block, and when the two-leg support is in the first state, the first limiting portion abuts against the protruding portion to limit rotation of the supporting leg.

As a further improvement of the present invention, the fixed block is further provided with a second limiting portion, and when the two-leg support is in the second state, the pivot block abuts against the second limiting portion to limit the rotation of the supporting leg.

The invention also provides a bicycle which comprises a frame, an annular chain and the double-foot support, wherein the double-foot support is fixed on the frame, the fixed block and the pivoting block are positioned between the chains in the height direction, and the two supporting feet are arranged on two sides of the chain.

The invention has the beneficial effects that: according to the double-foot support, the pivoting block is in pivoting connection with the fixing block, so that when the double-foot support is in the second state, the pivoting block is lifted, the chain can be prevented from contacting the double-foot support, and interference is avoided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 3, the bicycle of the present invention includes a frame 1, a chain in a ring shape, and a both-feet support 2. The two-foot support 2 is supported on the ground to ensure that the bicycle does not fall down.

The double-foot support 2 comprises a fixed block 21, a pivoting block 22, two supporting feet 23 fixed on two sides of the pivoting block 22, a connecting spring 24 and at least one pedal plate 25 connected with the supporting feet 23.

The double-foot support 2 is fixed on the frame 1, the fixed block 21 and the pivoting block 22 are positioned between the chains in the height direction, and the two supporting feet 23 are arranged on two sides of the chains. In this embodiment, the fixing block 21 is fixed to the frame 1.

The biped support 2 has a first state in which the support leg 23 supports the ground and a second state in which the support leg 23 is raised. When the double-foot support 2 is in the first state, the bicycle can stand on the ground, and when the double-foot support 2 is in the second state, the bicycle can run normally.

The height of the fixed block 21 when the double-foot support 2 is in the second state is higher than the height of the fixed block 21 when the double-foot support 2 is in the first state. Specifically, in this embodiment, the lower end of the fixed block 21 is connected with the upper end of the pivot block 22, when the bipedal support 2 is in the first state, the pivot block 22 is arranged up and down, and when the bipedal support 2 is in the second state, the pivot block 22 is inclined by a certain angle, so that the bottom of the pivot block 22 is raised, and then the pivot block 22 can be prevented from contacting the chain, and the bicycle is prevented from shifting so that the lower chain is raised and contacts the pivot block 22 of the bipedal support 2.

The fixed block 21 is n-shaped and opens toward the pivot block 22. The fixing block 21 is internally provided with a first cross beam 213, the outer side surface of the fixing block 21 is provided with a first limiting part 211 and a second limiting part 212, and the first limiting part 211 and the second limiting part 212 are arranged at intervals along the front-back direction.

The pivot block 22 is u-shaped and opens toward the fixed block 21. The second beam 222 is disposed in the pivot block 22, the top end of the pivot block 22 is disposed with a protruding portion 221, the protruding portion 221 is formed to protrude forward, and when the two-leg support 2 is in the first state, the first limiting portion 211 and the protruding portion 221 abut against each other up and down to limit the rotation of the support leg 23.

In this embodiment, the pivot block 22 and the fixed block 21 are both made of iron material, so that the strength is high.

When the two-leg support 2 is in the second state, the side edge of the pivot block 22 abuts against the second limiting portion 212 to limit the rotation of the support leg 23.

Two ends of the connecting spring 24 are respectively connected with the fixed block 21 and the pivoting block 22. In this embodiment, the two ends of the connecting spring 24 are respectively connected to the first beam 213 and the second beam 222. The connecting spring 24 is used for switching the double-foot support 2 between the first state and the second state, so that tension is provided, and the folding and the unfolding are easier.

The bottom of the two supporting feet 23 is provided with a cushion block 231 for supporting on the ground. When the bipedal support 2 is in the first state, the footboard 25 is supported. The arrangement of the cushion block 231 can increase the contact area between the supporting leg 23 and the ground, and improve the stability of the support. The pedal 25 and the two supporting legs 23 form a triangular structure, so that the stability of the support can be further improved.

According to the double-foot support 2, the pivoting block 22 is pivotally connected with the fixed block 21, so that when the double-foot support 2 is in the second state, the pivoting block 22 is lifted, the chain can be prevented from contacting the double-foot support 2, and interference is avoided.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
