Description

Multi-purpose combined foldable cycle

The invention relates to Folding Bicycle, particularly collapsible many inventions with the combination bicycle.

Transport in order to solve the short-distance luggage of travelling, and the needs that arrive whilst on tour moderate distance self communications and transportation of nonlocal town and country.So far the portable self-service vehicle that still need a kind of special construction, several known Folding Bicycles are arranged, they are function singleness mostly, and be not convenient for the long-distance vehicle such as getting on-off automobile, train, a kind of collapsible baggage car that pulls is arranged, its effect is only limited to the baggage handling of limited distance in the scopes such as station, harbour, and mode of operation is original.

The purpose of this invention is to provide a kind of Folding Bicycle, it can be folded up, and carries the long-distance vehicle such as getting on-off automobile, train easily; Its speed and transport capacity reach the level of portable bicycle; It can have multiple function by simple assembling conversion.

Another object of the present invention is to solve in the residential housing of middle level, city, and weight is difficult up and down, and bicycle is difficult upstairs, bicycle parking difficulty, and the few problem in the elderly physical training place, city.

The present invention also becomes the important tool of a kind of infant's child care and children's physical training.

The scheme of its solution is two parts compound type before and after bicycle is divided into, the front part is adopted and is pulled the foldable luggage trolley style, with two small-sized front-wheels, the driving rear wheel part of similar common folding bicycle is adopted at the rear portion of car, make driving device with sprocket wheel or bevel gear shaft, adopt an articulation piece connection between the two parts of front and back.Two parts can separate or make up easily, and car load is the type of falling the three-wheel, and its brake system and safety facilities can adopt the public accessory of bicycle.

It is the standard form accessory of parts used on the car being made integral type that the present invention further improves.Be designed to two concentric sleeves as the axle sleeve with front-wheel, bearing installation only makes inner layer sleeve match with front axle between two-layer sleeve, makes bearing assembly and front-wheel become one conveniently assemble and disassemble.

The present invention is designed to pedal collapsible to shorten width over sides of car body when folding.

Feature of the present invention also is to change assembling mode and makes car body have various function.

Fig. 1 has described collapsible combination bicycle, and it is regulated fixer (4) front axle (5) front-wheel (6) by grip frame (1) front baffle (2) baggage rack (3) baggage rack and forms the car body first half, and front-wheel (6) is equipped with double-deck axle sleeve (14).The latter half of car body is made up of link span (9) spider (12) saddle (17) trailing wheel (13) and chain guard (15) pedal (16) etc.Link span (9) is connected by tie bolt (10) with spider (12).Link span (9) can serve as the axle rotary folding with tie bolt (10), link span (9) cooperates with spider (12) with spacing colluding (33), fixing by saddle bolt (11), saddle bolt (11) is controlled the effect of saddle (17) lifting in addition, two parts are connected by articulation piece (7) before and after the car body, articulation piece (7) can be an axle with the axle center A-A of link span (9) front end, relative to rotating flexibly, articulation piece (7) and front baffle (2) relative fixed, and realize combination easily or separately by preceding terminal bolt of articulation piece (7) (18) and fly nut (8).Trailing wheel (13) uses foot-operated brake (28) braking, (or brake with the wheeled pedal of solo flight).Pedal (16) is locked by positioning groove (31) locating dowel pin (32).

This basic vehicle is travelled steadily because three-wheel lands except that being used for travelling, also can be used for local delivery or as mother and sons' car of picking the child, below the description of each figure all based on this basic vehicle.

Fig. 2, collapsible combination bicycle folding lateral plan: after unclamping fly nut (8) link span (9) slightly upwards being carried, articulation piece (7) just can separate with front baffle (2).Car body just front and back separates, unclamp saddle bolt (11), spacing colluding (33) thrown off from saddle bolt (11), link span (9) can be the axle center with tie bolt (10) just, and rotary folding, saddle (17) also can descend and can rotate for middle mind-set any direction with the axle of supporting saddle, can dwindle the space that car body occupies, the folding back of front vehicle body shape is seen Fig. 3, and this figure does not draw, and this figure only shows the staggered relatively position of front-wheel (6) dismounting back when car body is folding.

Fig. 3, collapsible combination bicycle folding front view: grip frame (1) front baffle (2) baggage rack (3) is folded in car body one side, lie against the car body opposite side after two front-wheels (6) dismounting, opening locating dowel pin (32) pedal (16) is axle with crank (29) outer end pin (30), and turnover is affixed on crank (29).

Fig. 4, the oblique drawing when this car is made juvenile's bicycle: grip frame (1) is turned down to the front lower place, and the appropriate position of the serration angle demodulator (27) of frame below baggage rack (3), unclamping saddle bolt (11), to fall saddle (17) fixing then to appropriate location, just become juvenile's bicycle, baggage rack also can be sat child on (3), and this vehicle is the vehicle that children play and take exercise.

Lateral plan when Fig. 5, this car are made electronic (bottle) car: baggage rack (3) is transferred to the lower end of front baffle (2), and placing storage battery (19) and electrical motor (20) just becomes electronic (bottle) three-wheel vehicle, and this vehicle adapts to the elderly and disabled person especially.

Fig. 6, this car are made the indoor car of doing exercises, lateral plan during the low pressure generator car: Mount support (21) plays stature behind the car body, this car just becomes the indoor car of doing exercises, the anxiety that exhausted nothing is toppled over: join low voltage generator (22) storage battery (23) as refilling on support (21), just the available generating electricity from manpower of this car.(adorn the current/voltage control in addition and transfer device), this kind vehicle is specially adapted to outlying areas without electricity, and the standby low potential source of area as household electrical appliances such as vision receivers that often have a power failure.

Fig. 7, the oblique drawing when this car front portion makes a tour folding chair: described the anterior several parts compositions of this car and taken steamer train camp chair during the journey.

Fig. 8, the oblique drawing when the baggage car purposes is made in this car front portion: this car front portion can separate with the rear portion, uses as baggage car separately, and for light, front-wheel can be used standby steamboat (24) in this car annex, dotted line steamboat among the figure instead.

Fig. 9, the oblique drawing when perambulator is made in this car front portion: baggage car installs the little wheel carrier of annex H type (25) steamboat (24) additional, and connecting element iron bar (26), reaching software nylon hanging basket (34) just becomes perambulator, and two groups of wheels make perambulator have stability before and after this car; Two groups of big trundles are used alternatingly before and after this vehicle utilization, also have a kind of performance of stair climbing.

Figure 10, this car portable folding front view: this figure describe and the latter half of folding back of car body is rested the front portion as luggage pull situation on the baggage car, and usage can be carried the getting on-off automobile train easily as shown.

It is all convenient that the present invention makes up dismounting, just can be assembled into bicycle by luggage less than 1 minute, and volume is little, and is in light weight, partable, and a car is multiplex, at home travelling, all-ages, this kind combined type car adapts to China's reality especially.

Parts of the present invention can be used the conventional method manufacturing, and the parts such as its link (9) tripod (12) trailing wheel (13) (comprising bike spoke) pedal (16) also can be produced with the injection molded method.
