CN2271140Y - Arc wheeless toy vehicle - Google Patents

Abstract

The utility model relates to a cambered vehicle without wheels, particularly a children's toy vehicle which is pushed to advance by the principle of a gravity action without being driven by any motors. The utility model uses two cambered plates to make a bracket, the inner side of each cambered plate is provided with a plurality of directional rotating strips, the directional rotating strips and the cambered plates are provided with tension springs, and the rotating direction of the vehicle without wheels is controlled by a multi-head lacing wire. The utility model has the advantage of simple structure, and is a necessary children's toy vehicle in large-scale amusement places.

Description

A kind of arc wheelless car

The utility model relates to a kind of toy for children.

At present, the kind of car is a lot of in the toy for children, but wheelless car, does not need motor-drivenly but not have, and particularly at large-scale recreation ground, for the enjoyment that excites children to play better, makes them that novel sense be arranged, and it is just very necessary not have the wheel toy car.

The purpose of this utility model is the children toy car that proposes a kind of not belt wheel, increases the enjoyment of children to playing.

The parallel symmetry of arc that it is arc with two bottoms that the purpose of this utility model is achieved in that with two connecting rods couples together, or wooden horse or other similar object be installed on two arcs, two arcs are connected and fixed, in the inboard of every arc several directed rotating bars are housed all, be fixed with fixing rotating shaft, and it can freely be rotated, spacing between the directed rotating bars equates, each directed rotating bars and arc all have an extension spring, the alignment pin that several and directed rotating bars symmetry are arranged on arc, several lacing wire guide rings are arranged on the arc, bull lacing wire line passes each lacing wire guide ring, be used for controlling wheelless car and turn, alignment pin and extension spring are used for controlling directed rotating bars and cross the fixedly angled α of arc diameter line of the AnchorPoint of rotating shaft; And when not stressing, get back to original position, and the two ends of directed rotating bars are circular-arc, its lower end will exceed arc arc limit one segment distance, determines the optimum value at α angle according to the distance between this segment distance that exceeds and each the directed rotating bars.In directed rotating bars upper end one joint pin is arranged, be used for connecting extension spring and lacing wire, make its position that can control directed rotating bars, when lacing wire is strained, the rotating bars lower end rotates to the position concordant with the arc circular arc round about, and this moment, arc lost walking function.Elaborate principle of the present utility model and structure below in conjunction with accompanying drawing: the arc 1 parallel symmetry that is arc with two bottoms with two connecting rods is connected and fixed, in the inboard of each piece arc 1 by several fixedly rotating shaft 3 fix several directed rotating bars 2, orientation is revolved.The spacing of changeing between the bar equates, there is a joint pin 6 upper end of each directed rotating bars 2, on each joint pin 6 He on the arc 1 extension spring 5 is being arranged all, right side symmetry near directed rotating bars 2 on arc 2 has alignment pin 4, there is a lacing wire guide ring 7 on each directed rotating bars 2 next door on arc 1, and bull lacing wire line 8 passes lacing wire guide ring 7.Bull lacing wire line several minutes lacing wire in 8 fen branch line links to each other with joint pin 6.Walking principle of the present utility model is: when arc is rolled to directed rotating bars and contacts with ground, contact point a just becomes fulcrum and AnchorPoint, because the effect of gravity G, directed in addition rotating bars and the angled α of vertical gravity line, so directed rotating bars must rotate to the b direction, because fulcrum a is on directed rotating bars, so being the axle center with a, moves arc to the C direction, along with arc rolls, when not stressing, gets back to directed rotating bars original position again, so alternately back and forth, the arc wheelless car just can have been walked.

The utility model is simple in structure, practical, will bring a lot of enjoyment to children when large-scale recreation ground is played, and is a kind of good toy for children.

Embodiment: 1 meter of the utility model arc length, 0.5 meter of two boards spacing, long 100 millimeters of directed rotating bars, wide 20 millimeters, 50 millimeters of mutual spacings.

Claims (1)

1, a kind of arc wheelless car, it is characterized in that: the parallel symmetry of arc [1] that is arc with two bottoms with two connecting rods is connected and fixed, in the inboard of each piece arc [1] by several fixedly rotating shaft [3] fix several directed rotating bars [2], spacing between the directed rotating bars [2] equates, there is a joint pin [6] upper end of each directed rotating bars [2], upward and on the arc [1] extension spring [5] is arranged all at each joint pin [6], the right side symmetry that goes up near directed rotating bars [2] at arc [2] has alignment pin [4], going up each directed rotating bars [2] next door at arc [1] has a lacing wire guide ring [7], and bull lacing wire line [8] passes lacing wire guide ring [7].
