Description

Multipurpose jumping cycle

The utility model mainly is also can make infant cradle doss and transportation means at ordinary times for entertainment for children and the device that has sports.

Current, large-scale public place of entertainment is provided with the spring trampoline mostly, children jump in the online jumping that becomes with knot, by its elastic force, with children's body, constantly upspringing falls, and tempers this kind to carry out amusement, facility, structure is big, and children can not only upwards jump, also can jump forward simultaneously, this is the formed large-area advantage of macrostructure, is difficult for moving but also bring thus, and needs the shortcoming in big place.Fill out the rural area in the city that does not have this kind facility, though or to have the city of this kind facility, distance to want to carry out entertainer's residence far away, then to reach the hope of this kind amusement, just difficult, particularly think whenever and wherever possible, carry out this kind amusement, just more impossible.

The utility model is just at the shortcoming of above-mentioned large-scale fixed bed and the design-calculated motor-tricycle.This bassinet structure is little, and area is also little naturally, wants constantly to make progress the place ahead to jumping on limited area, not may, in order to remedy this defective, on structure design, utilized the contractility of spring, make it to act on a series of members, driving trolley is constantly intermittently advanced, and to form a kind of bed surface of continuous extension, accepts the children's body that constantly upwards takeoffs forward and fall, thereby reach the place ahead that makes progress continuously to jumping, to carry out the purpose of amusement exercise.

The purpose of the utility model is achieved like this, and at first on the chassis 1 made from angle bar, upright last four endowels 2 are fixed by nut 3, and overlapped compression spring 4 thereon.The framework that angle bar is made and with knot trampoline 5 into the net again, from four jiaos circular hole, pack into tubing string 2, be pressed on the stage clip 4, afterwards, with chassis 1 and trampoline 5 same sizes take over a business 6, be enclosed within the upper end of tubing string 2, and be fixed with nut 7, to strengthen the stability of tubing string 2, more than constitute car body.

The movement structure that bed surface constantly extends is achieved like this, promptly on the little axle 10 directly over the little axle 9 of fixing vehicle wheel 8, running-fit one cylinder 11 at its end, is fixed a gear 12 simultaneously one and gear 12 ingear tooth bars 13, be fixed on the appropriate location of trampoline 5, so as trampoline 5, by gravity, move down, and the gravity disappearance, trampoline 5 is held up by stage clip 4, when moving up, driven gear 12 back and forth, do the both forward and reverse directions rotation.At the other end of cylinder 11, load onto a ratchet 14, it connect with big gear wheel 15, on the ratchet 16 that is fixed together, when ratchet 14 was clockwise with cylinder, ratchet slipped over by the inclination direction of tooth on ratchet, do not drive ratchet 16, when tooth bar 13, along with trampoline 5 rises, during driven gear 12 counter-rotatings, ratchet inserts in the teeth groove of ratchet, promote its rotation, the gear 15 that is fixed together with it, also rotation thereupon, and gear 15, be be fixed on axletree on miniature gears 17 be meshed, when gear 17 is driven by gear 15, when turning over the as much number of teeth, wheel 8 also turns over same angle, the vehicle body one section needed distance (being decided by ratio of number of teeth) of advancing.Limiting pin 18, it is on ratchet 14, bores a hole big than cotter diameter, penetrates pin, and ratchet 14 is being done when clockwise, the reason angle is excessive and tilt, so that when reversing, can not reset, and does not have the effect that promotes ratchet.In when counter-rotating, because axle is big in the hole, ratchet is having after rising and falling up and down ground on the ratchet, does not hinder it to slip over the flank of tooth and falls into teeth groove.

Doing the cradle time spent, the screw that connects click can be turned on respectively and be unloaded, in addition bolt being penetrated the axis hole of the ratchet on big gear wheel 15 and the cylinder 11 and another gives and boxing out in 19, the two directly is associated in together, again stretcher 20 is hung on the trampoline 5, when pin on pedal, depress when lifting, stage clip is made fore and aft motion, tooth bar makes the positive and negative rotation of the gear that is engaged with in process up and down, pass through cylinder, the also positive and negative thereupon rotation of big gear wheel 15, to drive the positive and negative rotation of miniature gears, car promptly rolls back and forth, the existing up-down vibration of cradle this moment, crank motion is arranged again, and the baby is very easily sleeping.

When making transportation means, the extraction spring lifts ratchet and gets final product.

When idle, unload screw 3 and screw 7, remove thing such as column and can place the corner.

Claims (2)

1, a kind of high-mobility, multipurpose, wheeled vehicle motor-tricycle is being connected by two rectangular upper rminal disc low bottom-discs and four endowels, and on the car body of forming, useful angle bar is made framework and with knot trampoline into the net, cylinder, tooth bar, stage clip, big miniature gears, ratchet, ratchet, wheel, pedal is characterized in that: compression spring sleeve is on tubing string, and trampoline is by its circular hole of four jiaos, be enclosed within on the stage clip, cylinder one end is fixed a gear, the other end, fix a ratchet, tooth bar is fixed on four jiaos of trampolines.It cogs with cylinder and is meshed, and ratchet and another gear are conjuncted, and this conjuncted and cylinder all is actively tied on the little axle directly over the axletree, wheel and above-mentioned beyond miniature gears, all be fixed on the axletree.

2, motor-tricycle according to claim 1 is characterized in that: ratchet is relative with ratchet, and ratchet connects on ratchet.
