Abstract

The present invention discloses a manual control elevating saddle of a bicycle, which is provided with a saddle pillar 7 whose one side is provided with rack bars 12, wherein the rack bars 12 are engaged with a gear 11 installed in a supporting member 3, a closed brake is arranged on an end shaft of the gear 11, and the brake torque of the brake is adjusted by a manual control mechanism to cause the saddle to be smoothly elevated; the elevating heigh and the elevating speed can be continuously adjusted, and the structure is firm. In addition, a rubber spring 10 is installed between a circular bead 6 of a sleeve barrel, and a spring base 8 to cause the elevating saddle to have good buffering and vibration damping effect.

Description

Hand elevating saddle of bicycle

The present invention relates to a kind of hand elevating saddle of bicycle.

The manual elevating bracket saddle of a kind of bicycle that in Chinese patent CN862099710, distributed.This manual control elevating bracket saddle is the pawl type pin that has shell fragment at original one of the binding bolt position setting-in locking saddle admittedly of bicycle, saddle pillar can slide up and down in sleeve, saddle pillar is made polyhedron or spline body, and the pin-and-hole that equidistant brill one row cooperates with pin on its one side towards pin.The start-up control handgrip can be handled locking pin and insert in any one required pin-and-hole of seat saddle, realizes the purpose of seat saddle lifting.But should manual control elevating bracket saddle start, stop suddenly, rising or falling speed can not be regulated, and adjustable height is discontinuous, and pin, pin-and-hole, binding bolt and be subjected to stress greatly with Kong Jun on the vehicle frame that this bolt matches are fragile and loosening, influence result of use.

The objective of the invention is provides a kind of hand elevating saddle of bicycle at above-mentioned shortcoming, and not only lifting is steady for it, and adjustable height and rising or falling speed are adjustable continuously, and structure is firm, and arranged enough service life.

The scheme that the present invention takes is: have the saddle pillar 7 that can slide up and down in sleeve 5, sleeve 5 is fixed on seat tube 4 upper ends, on saddle pillar 7, also be set with a pull back spring 9, its difference is that a side of saddle pillar 7 has tooth bar 12, connect firmly a supporting member 3 in the upper end of seat tube 4, be equipped with in the supporting member 3 and tooth bar 12 mating gear 11, gear 11 1 ends connect firmly mutually with a normally closed brake.

Gear of the present invention, rack mechanism are compared with aforementioned pin-and-hole structure of the prior art, following advantage is arranged: owing to gear, tooth bar always are in engagement, thereby handle reliably, adjustable height has continuity, also makes the mechanical strength of part significantly improve and for ease of maintenaince; Again owing to dispose drg in the device, thereby available manual mechanism changes the friction braking moment of this drg, to reach the purpose of regulating rising or falling speed.

In sum, the present invention can make the rider at any time with saddle by required speed, drop to enough low reposefully in addition can be reduced to both feet can step on the position on ground, saddle can be adjusted to the labour-saving height the most of enough height-by bike with suitable speed again, and unlikely worrying met emergency situation and had little time to get off.

Fig. 1 is the cutaway view of jacking system;

Fig. 2 is the A-A cutaway view among Fig. 1;

Fig. 3 is the transverse sectional view of another embodiment of saddle pillar;

Below in conjunction with accompanying drawing, embodiments of the invention are further described.

In saddle lifting device shown in Figure 1, saddle pillar 7 its tooth bars 12 that one side has a tooth bar 12 towards the car rear to, this saddle pillar 7 and sleeve 5 free-running fits, sleeve 5 and standpipe 4 upper end pore flush fits, the top of saddle pillar 7 connects firmly a spring perch 8, at spring perch 8 and 6 of sleeve shoulders spring 9 and rubber spring 10 are housed, supporting member 3 connects firmly mutually with standpipe 4 upper ends, and gear 11 is packed in the horizontal direction hole of supporting member 3 and is meshed with tooth bar 12.In conjunction with Fig. 1, Fig. 2, the left end shaft of gear 11 is installed on the supporting member 3, cooperate for radially reaching endplay between the two, other end axle and nest 16 free-running fits, make gear 11 to rotate and end float misalignment does not take place, the other end axle of gear is equipped with a normally closed brake, and its brake wheel is by holding screw 12, key 15 location.The hole of shift fork 2 is a free-running fit with the mandrel that is fixed on the saddle pillar.One end of spool 1 is connected with shift fork 2, and the other end is connected with control handgrip on being installed in bicycle handle bar.When the rider needs saddle to descend, with hand with suitable strength start-up control handgrip, when driving spool 1 and shift fork 2, the fork of shift fork 2 moves adjusting bolt 13, thereby make drg have suitable friction braking moment, descending speed with the control saddle, when the needs saddle rises, rider's hand motion also as described above and accompany by double-legged Pedalling, buttocks is risen, when saddle reaches required height, unclamp handgrip, drg still returns to closure state, and saddle promptly stops on the required height and position.

The present invention is not subjected to the restriction of embodiment, can change in many places.Drg can change shoe type or other form into.The saddle pillar 7 and the higher plastics of gear 11 usable intensity that have tooth bar adopt mould molding to make, and also can adopt different process, structure to make with metal.Pull back spring 9 can also change into and being installed in the bicycle profile tube 4.

Claims

1, a kind of hand elevating saddle of bicycle, has the saddle pillar 7 that can in sleeve 5, slide up and down, dispose the spring 9 that saddle pillar is resetted, sleeve 5 is fixed on seat tube 4 upper ends, a side that it is characterized in that saddle pillar 7 has tooth bar 12, connect firmly a supporting member 3 in the upper end of seat tube 4, be equipped with in the supporting member 3 and tooth bar 12 mating gear 11, gear 11 1 ends connect firmly mutually with a normally closed brake.

2, by the described manual lifting saddle of claim 1, it is characterized in that the top of saddle pillar 7 connects firmly a spring perch 8, rubber spring 10 is housed at spring perch 8 and 5 in sleeve.
