Description
本發明是有關於一種腳輪,特別是指一種具有止動煞車功能的腳輪。 The present invention relates to a caster, in particular to a caster with the function of stopping and braking.
一般為了移動方便,通常會在乘載物品的載台下方安裝數個腳輪。而為了防止該載台在地面不平整的地方自行移動,會在該腳輪上設置煞車機構。台灣專利I451984揭露的煞車輪組,該煞車輪組由一控制組、一煞車組,及一車輪所組成,該車輪上具有數個煞車卡槽;該煞車組主要是具有一樞軸、一與該樞軸相連之煞車塊,及一設置於該煞車塊上的卡掣塊;該控制組主要具有一固定塊,及一設置於該固定塊內的控制塊,及一與該樞軸相連之滑塊。利用該控制塊的導滑面帶動該滑塊上下移動,進而帶動該樞軸去連動該煞車塊,使該卡掣塊嵌入煞車卡槽中達到煞車的效果。 Generally, in order to facilitate the movement, several casters are usually installed under the carrier. In order to prevent the carrier from moving on its own on uneven ground, a brake mechanism is provided on the caster. The brake wheel set disclosed in Taiwan Patent I451984 is composed of a control group, a brake group, and a wheel. The wheel has several brake grooves; the brake group mainly has a pivot, a and The brake block connected with the pivot and a catch block arranged on the brake block; the control group mainly has a fixed block, a control block arranged in the fixed block, and a control block connected with the pivot Slider. The sliding guide surface of the control block is used to drive the sliding block to move up and down, thereby driving the pivot to link the braking block, so that the catch block is embedded in the braking slot to achieve a braking effect.
雖然該腳輪解決了煞車的問題,但該滑塊與該導滑面之間僅利用靠抵的方式帶動,在釋放該控制塊時,因釋放時的瞬間彈力易造成滑塊偏卡於該導滑面或是該固定塊上,導致無法順利將該 滑塊復歸回非煞車的位置,要再次驅動該控制塊煞車時便無法正常操作。 Although the caster solves the problem of braking, the slider and the sliding guide surface are only driven by abutment. When the control block is released, the slider is easily stuck in the guide due to the instantaneous elastic force at the time of release. Slippery surface or the fixed block, resulting in failure to smoothly remove The slider returns to the non-brake position, and it cannot operate normally when the control block is driven to brake again.
本發明之目的,是在提供一種能夠克服先前技術的至少一個缺點的腳輪。 The purpose of the present invention is to provide a caster that can overcome at least one of the disadvantages of the prior art.
