Abstract
The invention discloses a multifunctional castor structure, aims to overcome defects that a conventional castor only has functions of positioning, braking or steering and braking, and suitability is insufficient. The multifunctional castor structure comprises a positioning seat, a rotary seat, a latch member, a wheel, a brake swing member, a vertical rod set, a latch set, a transverse rod, an operating pedal and a relief pedal. The operating pedal is pedaled downwards or pulled up so as to allow the vertical rod set to drive the latch set to latch with or drop off the latch member fixedly arranged on the rotary seat and to drive the brake swing member to latch with or drop off the wheel pivoted on the rotary seat, accordingly the castor can execute functions of steering, positioning, braking and the like as required, and using convenience of the castor can be improved.
Description
Technical field
The present invention relates to a kind of castor, refer to that especially a kind of tool turns to, the fixed Castor structure to functions such as, Brake cars.
Background technology
Generally in order to make carrier (sick bed, precision instrument or bench board ...) conveniently moving, laborsaving, usually in the carrier below, dispose castor.And castor at the beginning is to be the non-rotatable design of a kind of fixed type, cause carrier only can keep straight on and can't turn, for this reason, develop on the market a kind of rotary castor, the function that can turn so that this carrier displacement to be provided.Subsequently, again for prevent can be because of the ground injustice when this castor is static, or be subject to the other factors automatic moving, therefore this castor is designed a kind of pedal that disposes, can allow the people control the stop of this carrier displacement Hou De Brake car, such as TaiWan, China patent announcement I338633, I343876, M424278, M422488, No. M414337 etc., all show a kind ofly there is pedal and can advance the castor of capable Brake car stop.
Yet, the castor of these common Ju Brake car functions uses situation still to have the following defect that need improve immediately in reality: when the rotary castor of this bearer configuration You Ju Brake car function, this carrier is in mobile process, because this castor can rotate arbitrarily, make this carrier in the process of craspedodrome displacement, easy of bestowing the thrust inequality on this carrier, and make the sense of displacement of advancing of this carrier be difficult for being controlled.
Therefore, when this bearer configuration has rotary castor, although this carrier can be looked demand and be carried out smoothly turning action, but have the advance defect of sense of displacement of wayward this carrier in the process of craspedodrome displacement, when this bearer configuration has the most traditional castor (the non-rotatable castor of fixed type) again, although this carrier is obtained control on the sense of displacement of keeping straight on, be difficult for carrying out the displacement of turning.

The above is structure and the configuration explanation thereof of each primary member of the embodiment of the present invention.Make flowing mode and effect makes the following instructions as for of the present invention.
When castor of the present invention carries out turning function, consult shown in Fig. 6, make the normality rank section 85 of this operating pedal 80 compress with the compression zone 72 of this cross bar 70, now, the card convex section 633 of the ratchet clamping part 621 of this first tooth part 62 and this second tooth part 63 breaks away from respectively clip tooth 22 and the clip hole 21 of this holding piece 20, simultaneously, Gai Brake car goods of furniture for display rather than for use 40 De Brake skiving sections 43 break away from the gear teeth section 31 of this wheel body 30, in order to do this rotary seat 10 is rotated relative to this positioning seat 100, this wheel body 30 rotates relative to this rotary seat 10, accordingly, be provided with the action that the carrier of castor of the present invention can be turned to.
When the Hang Brake car of castor Jin of the present invention function, consult Fig. 3, shown in 7, trample the operation of this operating pedal 80 and step on section 83 at first downwards, these operating pedal 80 De Brake car rank sections 86 are compressed with this compression zone 72, reach second of this operating pedal 80 and support the second releasing protuberance 95 that face 88 abuts against this releasing pedal 90, now, this cross bar 70 moves a distance towards these the first vertical pole 51 directions, allow this first vertical pole 51 and this second vertical pole 52 to bottom offset one distance, simultaneously this first, two vertical poles 51, 52 ratchet clamping parts 621 that drive this first tooth part 62 are fastened with the clip tooth 22 of this holding piece 20, in order to do this rotary seat 10 can't be rotated with respect to this positioning seat 100, in addition, the second end 521 of this second vertical pole 52 compresses Gai Brake car goods of furniture for display rather than for use 40 cw pivots of Gai Brake car compression zone 42 Rang and puts an angle, the Brake skiving section 43 of this Brake car goods of furniture for display rather than for use 40 of relief is equipped in the gear teeth section 31 of this wheel body 30, in order to do this wheel body 30 can't be rotated relative to this rotary seat 10, accordingly, be provided with the function that the carrier of castor of the present invention can the stop of Da Cheng Brake car.
As while wanting Xie Chu Brake car function, consult shown in Fig. 8, can trample the releasing of this releasing pedal 90 downwards and step on section 93, make second of these the second releasing protuberance 95 these operating pedals 80 of pushing and pressing support face 88, pivotable one angle between 80 up times of this operating pedal, the state that the normality rank section 85 that returns to this operating pedal 80 and the compression zone 72 of this cross bar 70 compress, its state as shown in Figure 6.
When castor of the present invention carries out orientating function, consult Fig. 3, shown in 9, at first upwards pull the operation of this operating pedal 80 and step on section 83, directed rank section 84 and this compression zone 72 of this operating pedal 80 are compressed, reach first of this operating pedal 80 and support the first releasing protuberance 94 that face 87 abuts against this releasing pedal 90, now, this cross bar 70 has the space that one day, these the first vertical pole 51 reversing senses moved, and interconnective first, two vertical poles 51, 52 Gai Brake car goods of furniture for display rather than for use 40 De Brake car compression zones 42 of Bei upwards push against a distance, simultaneously this first, two vertical poles 51, the 52 card convex sections 633 that drive this second tooth part 63 are fastened with the clip hole 21 of this holding piece 20, this rotary seat 10 can't be rotated with respect to this positioning seat 100, in addition, Gai Brake car goods of furniture for display rather than for use 40 De Brake car compression zones 42 of You Yu are no longer compressed by the second end 521 of this second vertical pole 52, therefore Gai Brake car goods of furniture for display rather than for use 40 De Brake skiving sections 43 break away from the gear teeth section 31 of this wheel body 30, this wheel body 30 is rotated relative to this rotary seat 10, now, because this rotary seat 10 can't rotate with respect to this positioning seat 100, and this wheel body 30 is able to rotate relative to this rotary seat 10, therefore, the carrier that is provided with castor of the present invention is carried out the displacement of specific direction.
While as wish, removing orientating function, consult shown in Figure 10, can trample the releasing of this releasing pedal 90 downwards and step on section 93, make first of these the first releasing protuberance 94 these operating pedals 80 of pushing and pressing support face 87, this operating pedal pivotable one angle between 80 inverse times, the state that the normality rank section 85 that returns to this operating pedal 80 and the compression zone 72 of this cross bar 70 compress.
In sum, the present invention really reached make the visual demand of this castor and carry out turn to, directed, is Ji functions such as Brake cars, to promote the ease of use of this castor, and the various embodiments described above and diagram are only preferred embodiment of the present invention, when can not with restriction scope of the invention process, the equalization of generally doing according to the present patent application the scope of the claims changes and modifies, and all should remain within the scope of the patent.
