Abstract

The utility model relates to a small-size third-wheel multifunctional wriggling vehicle which moves driven under the resultant force of hands, feet, a body weight, etc. by a shrinking and wriggling mode. The rear vehicle frame of a cross vehicle body is connected with the hinge of a front vehicle frame. The utility model uses a short shaft on the hinge as a shaft center and uses the sleeve pips of the vehicle frame as a supporting point by a top rod and a connecting rod which are hinged, and causes that the front vehicle frame is connected with a foot pedal. The upper part and the lower part of the front vehicle frame are respectively buckled with a tension spring. Two wheels are arranged on the vehicle shaft of the front vehicle frame, and a guide wheel is arranged on the vehicle shaft of the rear vehicle frame. Stopping-retreating gear wheels are arranged on the vehicle shafts. The utility model is a multifunctional fun vehicle which collects a body-building function, an entertainment function, climbing function, a ridging-up function and a transportation function.

Description

Multi-functional wriggling vehicle

The utility model---multi-functional wriggling vehicle belong to make a concerted effort to drive down with hand, pin and body weight etc., with the multifunctional small-size tricycle that mechanical-stretching wriggling mode is moved, be suitable for the elderly and children and do body-building, amusement, climbing, go up the ladder shopping, send use such as child.

According to the knowledge of the applicant: existing pedicab, toy tricycle are chain drive, can only do means of transport or toy use, and stairs-mover complex structure function singleness.

The purpose of this utility model is the shortcoming that is to overcome above-mentioned prior art, the utilization opposition thinking, design a kind of two-wheeled preceding single-wheel after the multi-functional wriggling vehicle that gathers multi-function in integral whole.

The purpose of this utility model is such realization: the back vehicle frame of cross vehicle body is connected with the front frame hinge, with the minor axis on the hinge is the heart, forward and backward vehicle frame is connected as a single entity, be fulcrum, make front frame and step tread plate become lever to link to each other by the push rod of hinge and the sleeve pipe of lever, former axletree, forward and backward vehicle frame is snapped with tension spring up and down respectively, two wheels are installed on the axletree of front frame, a directive wheel is installed on the axletree of back vehicle frame, all the retaining gear can be installed on the axletree, the retaining gear place on rear wheel is provided with the ejector pin device that can draw back.

Be cast with the pin cave massager that the protruding stake of the many rows of circular arc constitutes on the extension board face of step tread plate both sides, rear wheel is provided with wheel guard.

The retaining gear is a bicycle freewheel.

Adopt vehicle frame middle section, back to establish sleeve pipe at front and back vehicle frame infall, the front frame stage casing intersects with the back vehicle frame by the cotter axle on outside this sleeve pipe and links to each other.

Being provided with two at the push rod lower end can be how and the hand lever that rotates, and the hand lever lower end is arranged on many spring snappings of vehicle frame below and fixes.

When going upstairs ladder, adopt big wheel (28 inch), and planetary trundle (during 2-3), the time spent overhangs as umbrella.

Owing to adopt abovementioned technology, make to the utlity model has simple in structurely, compact, light, easy to manufacture, have in body-building, amusement, the climbing bank and send thing advantage such as make a gift to someone, and have stronger interest, can make multinomial exercise usefulness.

Describe in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the sketch of Fig. 1.

With reference to Fig. 1, Fig. 2, the cross vehicle body is that the back vehicle frame 4 of a rigidity is connected (pin connection) with front frame 11 by hinge 7, is the axle center with the minor axis on the hinge 23, and forward and backward vehicle frame (11,4) is connected as a single entity.Connecting rod 16 by the push rod 17 that is hinged and its hinge, 15 to be fulcrum on the pipe spreader of the axletree of front vehicle wheel 12, to make front frame 11 be connected (welding or the bolt connection) with step tread plate 14.Before and after vehicle frames (11,4) go up snappings (or socket) respectively and have the telescopic tension spring of changeable radical (10,19,19 can adopt hold chest expander).Two wheels 12 (can adopt spoke or disc shape wheel) are installed on the axletree of front frame 11, a guiding wheel 6 is installed on the axletree of back vehicle frame 4, retaining gear 7 all is installed on the axletree, back vehicle frame 4 can be in the fork of front frame 11 about twisting, 13 of the extension boards of step tread plate 14 both sides are gone up casting (metallic plate face or plastic running surface all can) has the protruding stake of the many rows of circular arc to constitute pin caves massage vessel, and the vehicle frame 4 of rear wheel is provided with wheel guard 5.Also connecting (socket) on the back vehicle frame 4 has telescopic pull bar 18 and is integral part with handle 20, or fixed integral piece.It all is prior art that connection is installed.Can also adopt vehicle frame 4 stage casings, back to be through in the sleeve pipe (not shown) at front and back vehicle frame infall, during vehicle frame can rotate after making, front frame 11 stage casings intersect with back vehicle frame 4 by the outer cotter axle (or bearing) that is provided with of this sleeve pipe and link to each other.Push rod 17 lower ends be provided with two can multidirectional rotation the hand lever (not shown), the many tension springs 10 below the lower end of hand lever is arranged on vehicle frame 11 draw button fixing, can make bent rowing and take exercise.When staff handle 20 is seated on the vehicle seat 1 (circular arc lateral seat stool), the seat descends because body weight makes, vehicle body increases and wheel on stopping gear 7 make rear wheel 6 motionless, promoting preceding two wheels 12 and rotating a segment distance forward.Simultaneously, step tread plate 14 rises, pull bar 18 turns forward, and with upper pulling force spring 19 and the 10 elongation energy storage of lower pulling force spring.Then both feet are placed on the step tread plate 14 firmly to the front lower place and pedal (also pin can be put on the massage vessel 13 of both sides, massage pin cave), both hands are firmly toward post-tensioning.At this moment and under the screen resilience of tension spring (10,19), can take turns and easily lift ground way up is held up, the preceding two-wheeled 12 motionless rear wheels that make are pushed ahead a segment distance, and vehicle body shortens.Promote front-wheel 12 then again under the gravity effect of health, beginning is the wriggling process for the second time.Come so repeatedly under the back operations, make dolly wave ground crawling forward, firmly frequency is high more, and the speed that dolly moves ahead is also just faster.Owing to retaining gear 7 (also the flywheel of available existing bicycle replaces) all will be arranged on three wheels, therefore can climb to go up bank and can stop and not fall back.When going upstairs the building, rank, need to adopt cart 28 inch, or planetary trundle (2-3 inch) (as umbrella, overhanging expression among the figure).Also the ejector pin 8 of 7 li reeves of zigzag retaining gear on the rear wheel 6 can be drawn back, second joint of small end is linked up with 9 draw on the crossbeam that hangs over back vehicle frame 4.So just can earlier block be shelved in the front lower place of preceding two wheels 12, only allow rear wheel 6 roll back and forth, can make multinomial health exercising onboard, not be subjected to the restriction in weather and place in the original place indoor.Also can sentence the accuser to the punishment facing the person he falsely accused and not lie leaning against on the spring of many arrangements of chest expander 19, both feet are placed on above the plate 5 of wheel 6 tops, the multinomial entertainment body-buildings such as sit-ups of bending over backward to draw the abdomen, and this all has certain effect to physique of strengthening the people, fat-reducing etc.
