Abstract

The invention provides a novel bicycle, and particularly relates to a riding-seating dual-purpose bicycle, of which the wheel span and the wheel base of a front chain wheel group and a rear chain wheel group can be changed. The novel bicycle comprises the components of a group of axial cavities or a bicycle frame main beam, of which the outer wall is a track, a telescopic beam rear fork with a pull bar, a directional upright pipe with a pull bar, a sitting posture upright pipe with a pull bar, a multi-purpose bicycle hanging rack which can be used as a back rest, a fin-shaped chain wheel axisbracket, a front crank sprocket group and a rear crank sprocket group, a front travelling wheel group and a rear travelling wheel group and the like; due to mutual drawing and positioning of the pullbars arranged among the components, the angles of the directional upright pipe and the sitting posture upright pipe and the length of the telescopic beam rear fork are synchronously changed, a rider can flexibly and reliably adjust the postures from the common forward lean riding mode to the lying backward sitting mode, so that the novel bicycle is suitably used for traveling medium and short distances at a low-speed or medium and long distances at a high-speed in urban or suburban areas in the forward lean riding mode or lying backward sitting mode; and in addition the novel bicycle has the advantages of reasonable and superior ergonomics and aerodynamics, novel structure, high overall strength, advanced joints and linkages and wide adaptability.

Description

The riding-seating dual-purpose bicycle of variable posture and wheelbase

Technical field:

The present invention relates to a kind of new bicycle, belong to the daily traffic leisure travelling instrument of riding instead of walk, suitable usefulness lean forward striding type the city do short-distance in low speed driving, and make the travelling of middle-long distance high speed on the outskirts of a town.

Background technology:

Existing riding type bicycle, can only do some accommodation to handlebar and seat according to user's height, riding posture basic fixed personal weight distribution too concentrates compressing buttocks and both arms to cause the tired and damage of musculature easily, the kinetic energy transmission efficiency is low, and because center of gravity is higher, poor stability, wind area is big, the air resistance coefficient height, effort and out of control easily when riding relatively at a high speed, increase its danger, ride for a long time and be easy to cause fatigue, therefore many product designers both domestic and external have done a large amount of research and development, in the recent period external (www.freshcreation.nl) website discloses a changeable type dual-purpose bicycle and has more reasonably solved some problems wherein, but and domestic disclosed (ZI 200620149577.x), (ZI200720017142.4), there is complex structure equally in a plurality of patent applications such as (ZI 200420008808.6), car body is bigger than normal, wheelspan is long partially, globality is poor, the more high shortcoming of manufacturing cost.

Summary of the invention:

The objective of the invention is the shortcoming and defect that exists at above-mentioned existing bicycle and design-calculated is a kind of can be according to difference ride road conditions condition and rate request, to the position of riding carry out from common lean forward striding type to after lie fast and reliable adjustment and conversion the sitting posture, joint and link gear advanced design, it is rationally superior to have novel structure, bulk strength height, ergonomics and aerodynamics, and comformability is new bicycle more widely.

Among the figure: (1) be vehicle frame main beam, (2) for direction standpipe, (3) for direction standpipe pull bar, (4) for versatile spindle support, (5) seat standpipe, (6) seat standpipe pull bar (positioning runner), (7) for being skew girder of vehicle frame for telescopic girder back vent pull bar, (11) for telescopic girder back vent, (12) for fin-shaped crank and chain-wheel bracing strut, (10) for snap close, (9) with car bag hanger, (8).

The specific embodiment:

The accompanying drawing that cooperates one of embodiment, Fig. 1, Fig. 5, Fig. 6 elaborates to addressing its technology contents before the present invention: vehicle frame main beam (1) axial bore or outer wall for the track front end be vertically fixed with front fork axle bed upper end versatile spindle support cooresponding with it (4) arranged and be equipped with can swing direction standpipe (2), seat standpipe (5) upper end is provided with the seat that can do multistage angle initialization and with car bag hanger (7), lower end and vehicle frame main beam (1) rear end is hinged, and can swing, (1) is along being fixed with fin-shaped crank and chain-wheel bracing strut (9) under the vehicle frame main beam, and before being installed, crank and chain-wheel organizes, telescopic girder back vent (11) is installed in the axial bore track of rear end, expansion bracket back vent pull bar (10), and after being installed, sprocket wheel organizes, described direction standpipe (2), seat standpipe (5), and telescopic girder back vent (11) is respectively by set pull bar interrelation interlock separately, and wherein direction standpipe pull bar (3) rear end and seat standpipe pull bar (6) front end are coaxial is connected and is entrenched in the set positioning runner in vehicle frame main beam both sides or upper edge (6) and seat standpipe (5) connects telescopic girder back vent pull bar (10).Between them mutually traction can under the restriction of positioning runner (6), the collapsing length of the pendulum angle of direction standpipe (2) seat standpipe (5) and expansion bracket back vent (11) can make synchronous fore-and-aft adjustment and change and can locate under the locking of snap close (8).

The present invention can make multiple variant under above-mentioned main invention main idea unmodified situation, thus described four embodiment of this case wherein the part-structure details is slightly different.

Wherein:

Fig. 5,6 is that one of embodiment positioning runner (6) is set directly at vehicle frame main beam (1) both sides;

Fig. 7,8 is for two its seat standpipes (5) of embodiment are fixed on rear portion, vehicle frame main beam lower edge, direction standpipe pull bar (3) and expansion bracket back vent pull bar (10) direct coaxial be connected and be entrenched in vehicle frame main beam (1) go up in the positioning runner (6) that both sides are provided with;

Fig. 9,10 is arranged on skew girder of vehicle frame both sides (12) on the vehicle frame main beam to positioning runner (6) for the variant of one of embodiment;

Figure 11,12 two variants for embodiment directly unite two into one direction standpipe (3) pull bar and telescopic girder back vent pull bar.

Variant of the present invention position and wheelbase are achieved in that the locking of opening with car bag hanger (7), the snap close (8) that discharges on the vehicle frame main beam pulls back seat standpipe (5), seat standpipe (5) spurs direction standpipe (2) swing inclination backward synchronously simultaneously under the effect of pull bar, seat standpipe (5) promotes telescopic girder back vent (11) synchronously by telescopic girder back vent pull bar (10) and skids off backward and locate on desired location, adjust seat standpipe (5) length and angle, upwards pulling locks to top dead point with car bag hanger (7), snap close (8) on the locking vehicle frame main beam (1), adjust direction standpipe (2) length, both finished from lean forward striding type to after the lie whole adjustment process of sitting posture.

The above only can not limit the scope of the invention process with this for part embodiment of the present invention, both changed with modification all should belong to the scope that patent of the present invention contains together generally according to the present patent application claim and the described simple equivalence of invention description content.
