Abstract
The utility model relates to a four-wheel pedal child bicycle of a reciprocating forward type, which can be used for body-building and amusement. The utility model is suitable for each family. The utility model is composed of a chassis assembly, four wheels (2) (12) (15), a chair (16), a car-shaped housing (1), etc., wherein the chassis assembly is composed of foot pedals (8), a driving connecting rod (9), a double crank shaft (11), a guide rod (4), a cavel (6), etc. The utility model has the advantages of free stop, safe and comfortable use, simple structure, beautiful appearance, etc. The utility model can be ridden and operated by children of ordinary families to achieve the purposes of amusement and exercise.
Description
The utility model relates to the back and forth foot-operated forward four-wheel perambulator that a kind of body-building, amusement are used.
How the apparatus for entertainment of foot-operated driving constitutes stop motion mechanism with pedal, crank, ratchet, chain, brake system etc.Two-wheeled or toy tricycle turn to by handlebar, and are detected in electronic dodgem with the four-wheel perambulator that bearing circle, pilot bar, goat's horn are formed the double front wheel of steering hardware.Former structure is simple and practical, and price is lower, but the safety when bend walking and sudden stop is not ideal enough; Latter's safety of walking is good, ride comfort, and function is more, but higher because of complex structure, price, is difficult to enter ordinary family, and children use and only limit to some public places.
Task of the present utility model provides a kind of improved foot-operated four-wheel perambulator, can be suitable for entering huge numbers of families.
The utility model is finished like this: constitute the chassis assembly of perambulator by pedal, drive link, two-way back bent axle, bearing circle and steering swivel system thereof etc., be equipped with four wheels and dolly shell body.
The utlity model has stop freely, safety and comfort, advantage such as simple in structure, handsome in appearance.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof:
Fig. 1 is the utility model schematic appearance.
Fig. 2 is the utility model chassis assembly constructional drawing.
Below in conjunction with Fig. 1, Fig. 2 concrete structure and the manipulation situation that the utility model proposes is described in detail, intactly.
The material that housing (1) useable glass steel, engineering plastics, iron and steel thin sheet equal strength suit becomes the roadlice shape of novelty attractive in appearance, and seat (16) can be configured as one.Wheel (2) (12) (15) is existing solid baby carrier wheel, also can be designed to inflate baby carrier wheel.The chassis assembly is configured in chassis (10) by stop system and steering swivel system and forms.By two one ends symmetry and there is stopping-off piece to be suspended on drive link (9) on sole (17) cross bar, place, the horizontal right angle of drive link (9) respectively is with a pedal (8), other end straight-bar is connected on the hyperbolic axle (11) of 180 ° of direction differences, hyperbolic axle (11) both sides are respectively adorned a bearing (14) and are fixed on rear portion, chassis (10), at hyperbolic axle (11) one ends the adhesion wheel (12) that an inboard is fixed with latch is installed, so that with the concentric run-in synchronism of bent axle, the other end is installed a differential wheel (2) free to rotate, just constitutes stop system.And can adorn the axis of orientation (4) that bearing circle (3), bottom turn into 80 ° of-100 ° of rocking arms by an end, recognizing 30 ° of-50 ° of inclination angles is inserted in the middle fixedly U type hole of pilot bar (7), pilot bar (7) two ends are hinged with an end of two goat's horns (6) respectively, two goat's horns (6) middle part is enclosed within respectively on the bar shaped goat's horn seat (5) that is fixed in chassis (10), turn back respectively 90 ° laterally in two goat's horns (6) bottom, load onto front vehicle wheel (15), promptly constitute steering swivel system.The housing (1) that has been shaped is installed on the assembly of chassis, and pedal (8) position is positioned at seat (16) the place ahead to be located on the lower side, and seat (16) is loaded onto bearing circle (3) near chassis (10), is finished product.Also accessory devices such as light, sound equipment be can be equipped with, complete body-building, amusement children apparatus formed.Each parts of chassis assembly are with reinforcing bar, steel or other material manufacture of sufficient intensity is arranged partially.
The utility model is to handle like this, and when the person of taking advantage of successively scrunched pedal (8) with pin, drive link (9) drove hyperbolic axle (11) rotation, is installed in the also run-in synchronism of adhesion wheel (12) of hyperbolic axle (11) one ends, and perambulator just can advance or retreat; When keeping pedal (8) static, this car promptly brakes and stops.During steering wheel rotation (3), the rocking arm of axis of orientation (4) bottom is then with the swing of angle, mat U type pilot hole swing pilot bar (7), drive an end of hinged goat's horn (6), make the terminal related same in the same way angular deflection of the goat's horn (6) that front vehicle wheel (15) are housed, finish a left side or right handling maneuver, and another can be around the terminal back differential wheel (2) that freely rotates of hyperbolic axle (11), when regulating perambulator and turning to interior outside the different differential of haul distance.
The dimensions of each parts of the utility model varies in size and designs with the perambulator global shape.The parts typical sizes specification of a kind of embodiment wherein: wheel (2) (12) (15) external diameter diameter 22cm; The long 7.5cm of pedal (8), wide 5.5cm; Drive link (9) is suspended on the long 25cm of an end bar on chassis (17), connects the long 43cm of an end bar of hyperbolic axle (11); Hyperbolic axle (11) diameter 1.6cm, long 41cm, hyperbolic width between centers 28cm that contrast is 180 °; Single height 7cm, wide 2.5cm; Axis of orientation (4) diameter 1cm, long 36cm; The long 8cm of right angle, chassis rocking arm; The long 28cm of U type pilot bar (7); The high 3.5cm in U type hole, wide 1.3cm are apart from pilot bar (7) 3cm; The high 7.5cm in goat's horn (6) middle part, the long 4.5cm of hinged pilot bar (7) one ends, the other end is rolled over 90 ° of long 6cm outward; Chassis (10) length overall 93cm, width: head 27cm, neck 14cm, middle part 40cm, rear portion 32.5cm; The high 21cm of sole (17), wide 30cm; Rear wheel (2) (12) wheelspan 38.5cm, front vehicle wheel (15) wheelspan 33cm; Front and back wheel wheelbase 68cm; Bearing circle (3) external diameter diameter 19cm; The long 96cm of housing (1), wide 41cm, high 22cm; Seat (16) cup depth 12cm, long 21cm, wide 19cm; Pilot bar (4) inclination angle is 40 °.
