CN2433162Y - Stick-up bicycle frame - Google Patents

Abstract

The utility model provides a stick-up bicycle frame for a double-driving bicycle, which has the functions of entertainment and body-building, and can produce a second driving force. The bicycle frame comprises a front vertical pipe welded on the front end of a bicycle beam and a boosting rod pinned on the bicycle beam. The utility model is characterized in that the back end of the bicycle beam and the back end of a stick-up arm are assembled together by a shaft; assembly holes arranged on an actuator are respectively arranged on the bicycle beam and the stick-up arm; the front end of the stick-up arm is provided with a connecting socket; the middle of the stick-up arm is provided with an assembly hole of a back wheel. When used, the stick-up bicycle which is made of the bicycle frame has the advantages of long force arms, large acting bicycles, simple structure, artful structure, novel and peculiar shape, labor saving, and high speed.

Description

Bicycle frame

The utility model relates to a kind of cycle frame, but particularly a kind of amusement, body-building produce second propulsive effort and realize two drive lift up bicycle used lift up vehicle frame.

The history of human existing centuries of the simplest walking-replacing tool bicycle, develop into today, the bicycle of countries in the world height class is a lot, but all be fixed mode on structure and performance, never have new breakthrough, traditional cycle frame is to be made of two triangular forms, the good advantage of steadiness is arranged, but also this advantage just makes people ignore the improvement and the innovation of vehicle frame, makes the performance of bicycle be confined to single state that drives always.

The purpose of this utility model provides a kind of bicycle frame, and it makes by the gravity of the pulling force of the power of pedaling of leg, arm and health and lifts up the arm two ends and replace up-and-down movement, but entertainment body-building and produce the vehicle frame of lifting up of second propulsive effort.

The purpose of this utility model is achieved in that this vehicle frame comprises that the preceding standpipe that welds mutually with vehicle frame and pin are contained in the boosting-rod on the beam, the rear end that it is characterized in that the car beam fits together with axle with the rear end of lifting up arm, the car beam is respectively equipped with the assembly hole that driving device is installed with lifting up on the arm, lift up the arm front end and clamped Connection Block, lift up the middle assembly hole that is provided with trailing wheel of arm.

Because the preceding standpipe of this vehicle frame is assembled mutually with traditional preceding steering hardware, Connection Block is assembled mutually with traditional middle shaft drive, trailing wheel is assembled on the trailing wheel assembly hole of lifting up arm, at the car beam with lift up the corresponding driving rack of configuration on the driving device assembly hole of arm, just can constitute two the driving and lift up bicycle.As long as successively the rear end by pedal and car beam makes and lifts up the arm two ends and alternately move up and down with the power of pedaling (comprising that pedal centers on the power-assisted rotation of the axis) health of leg and gravity, just can be simultaneously or asynchronously make driving rack and traditional actuator drives trailing wheel rotation, can realize that double driving bicycle lifts up the purpose of vehicle frame.Double driving bicycle simple and ingenious structure with this chassis mount one-tenth, the modern design uniqueness, it has overcome the deficiency of standard bicycle on structure and performance, change bicycle and had only single state that drives, but and lift up arm make rippling in entertainment body-building, health can obtain again having a rest, and has significantly laborsaving fireballing advantage.

The car beam of this vehicle frame can be made into single armed curved beam type and both arms inclined beam type, and other are constant.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the concrete structure scheme drawing of this butterfly.

Fig. 2 is the front view of the both arms inclined beam type vehicle frame among Fig. 1.

Fig. 3 is the birds-eye view of Fig. 2.

Fig. 4 is the front view of the single armed curved beam type vehicle frame among Fig. 1.

Fig. 5 is the birds-eye view of Fig. 4.

Describe concrete structure of the present utility model in detail according to Fig. 1-5.

1 preceding standpipe is welded on the front end of car beam 2 among the figure, boosting-rod 3 pin is contained on the car beam 2, the 4,5,8, the 10th, the dress hole that second driving device is installed, the rear end of car beam 2 with spools 6 with lift up arm 7 rear ends and assemble mutually, the 9th, the assembly hole of trailing wheel, Connection Block 11 clampings are at the front end of lifting up arm 7.

Claims (3)

1, a kind of bicycle frame, this vehicle frame comprises that the preceding standpipe that is welded on car beam front end and pin are contained in the boosting-rod on the car beam, it is characterized in that the rear end of car beam and lift up the arm rear end fitting together with axle, the car beam is respectively equipped with the assembly hole that driving device is installed with lifting up on the arm, lift up the arm front end and clamped Connection Block, lift up the middle assembly hole that is provided with trailing wheel of arm.

2, bicycle frame according to claim 1, the car beam can be made the both arms inclined beam type.

3, bicycle frame according to claim 1, the car beam can be made the single armed curved beam type.
