Abstract

The utility model discloses a bicycle saddle with a fast elevating mechanism. The saddle is installed on the saddle tube which is provided with two symmetry elongated slots and a row of vertical side holes which are vertical to the elongated slots; a spring is arranged in the saddle tube; both ends of the spring is respectively fixed to the end of the saddle tube and a fixing bolt; a hook head pin which is fixed to a support is connected with a rocking rod by a draw rod; a short draw rod penetrates through the annular slot of the rocking rod. Hands grasp a brake handle; the joint of the short draw rod elevates the rocking rod which drives the draw rod to have the hook head pin departed from the side holes on the saddle tube, and the saddle elevates at the reactive force of rider or the spring. Compared with the existing saddle, the utility model has the advantages convenient adjustment, safety in running, etc.

Description

Bicycle saddle with fast rise and fall adjusting machinery

The utility model relates to a kind of bicycle saddle with fast lifting mechanism.

Existing bicycle saddle if will regulate its height, must be unscrewed nut with spanner or other instruments, and apply external force and saddle is risen or decline, and then fastening nut.When running into the unforeseen circumstances emergency brake, because effect of inertia, the car band the people and also will be continued to slide forward, perhaps lack of equilibrium and toppling over, and this moment, the height of saddle can not descend, and cyclist's both feet can not in time land, thereby may have an accident.

The purpose of this utility model is to eliminate the dangerous hidden danger of existing saddle, and a kind of saddle rapid, driving safety---bicycle saddle of band fast lifting mechanism of regulating is provided.Regulate the height of saddle, if hold bicycle brake, when running into unforeseen circumstances, saddle is in cyclist's decline voluntarily under the effect of gravity, thus both feet land the generation that can avoid accident.

The utility model is achieved in that installs a cover saddle fast lifting mechanism on ordinary bicycle, saddle is contained on the saddle pipe, there is the elongated slot and of two symmetries to arrange the vertical side opening of spending at an angle of 90 on the saddle pipe with elongated slot, spring is housed in the saddle pipe, one end of the spring end of dowel fixes at saddle pipe, the other end is fixed on the bolt of rear end plate, bolt of rear end plate is contained in the line of centers intersection of pipe and standpipe, the gib head pin of control saddle pipe lifting is fixed on the bearing, bearing links to each other with clamping ring, and clamping ring is bolted on the standpipe, the gib head pin links to each other with pull bar, pull bar links to each other with rocking bar by set screw, and short rod passes the circular groove of rocking bar, and rocking bar is bolted on the pipe.Mention short rod as long as hold brake lever, the short rod joint lifts rocking bar, and the elastic force that rocking bar affects pull bar to make the gib head pin overcome plate spring leaves the side opening on the saddle pipe, just saddle can lifting under the application force of cyclist or spring.

Fig. 1 is the front view of the bicycle saddle of band fast lifting mechanism.

In conjunction with Fig. 1 the bicycle saddle of band fast lifting mechanism is further described.The lifting mechanism of saddle is made up of saddle pipe (2), standpipe (8), bolt of rear end plate (3), spring (4), pin (7), clamping ring (5), bearing (11), gib head pin (10), plate spring (9), pull bar (12), set screw (13), bolt (16), rocking bar (15), short rod joint (17), short rod (14).Saddle (1) is fixed on the saddle pipe (2), and saddle pipe (2) both sides process the elongated slot F with two symmetries, becomes 90 ° side to be drilled with the vertical side opening E of a row with elongated slot F.Spring (4) is installed in saddle pipe (2) lining, and an end is fixed on the bolt of rear end plate (3), and the other end is fixed on the end of saddle pipe (2) by pin (7).Bolt of rear end plate (3) is contained in the line of centers intersection of standpipe (8) and last pipe (18), and the elongated slot width of saddle pipe (2) is slightly larger than the external diameter of bolt of rear end plate (3), so saddle pipe (2) can slide up and down, but can not rotate.Short rod (14) links to each other with right brake lever (not drawing among the figure), short rod (14) passes the circular groove of rocking bar (15), rocking bar (15) is fixed on the pipe (18) by bolt (16), one end of pull bar (12) links to each other with rocking bar (15) by set screw (13), the other end links to each other with gib head pin (10), gib head pin (10) is fixed on the bearing (11), bearing (11) links to each other with clamping ring (5), bolt (6) is fixed on clamping ring (5) on the seat tube (8), the plate spring clamped circles of (9) one ends (5) are fixing, and the other end forces in gib head pin (10).When the saddle lifting mechanism is in the solid line position of Fig. 1, though promptly do not hold right brake lever or hold right brake lever but short rod joint (17) when not lifting rocking bar, gib head pin (10) inserts a certain side opening E of saddle pipe (2) under the application force of plate spring (9), saddle (1) promptly is fixed on a certain position, drive short rod joint (17) and lift rocking bar (15) to figure during the two-dot chain line position when holding right brake lever short rod (14), rocking bar (15) just affects pull bar (12) to make gib head pin (10) overcome the elastic force of plate spring (9) and leaves the side opening E of saddle pipe (2), if there is not external force or external force elastic force on saddle this moment (1) less than spring (4), under the elastic force effect of spring (4), then saddle (1) rises, the extreme higher position of rising is that saddle pipe (2) upward contacts with bolt (3) lower end of elongated slot F, if saddle this moment (1) has downward external force greater than spring (4) (comprise cyclist from gravity), then saddle (1) descends, the extreme lower position that descends is that saddle pipe (2) upward contacts with bolt (3) upper end of elongated slot F, and the ultimate range that rises or descend is the length that saddle pipe (2) is gone up elongated slot F.

Advantage with the bicycle saddle of fast lifting mechanism is easy to adjust, driving safety, the height of regulating saddle does not need instrument, at any time all can regulate brake lever and saddle is motionless slightly in travelling as long as hold right brake lever, in emergency circumstances, hold brake lever, the gib head pin leaves saddle pipe side opening E, and saddle is automatic descending under cyclist's self-gravity action, cyclist's both feet land, thereby have avoided the generation of accident.
