Description
本發明係有關於一種腳輪,尤指一種具有避震功能之腳輪結構。The invention relates to a caster, especially a caster structure with shock-absorbing function.
按,近代隨著工業革命的興起,越來越多的設備需要移動,腳輪的應用越來越廣泛,各行各業幾乎離不開腳輪,該腳輪使用時係裝設於設備(如推車、運送台車等)底部,藉由該腳輪與地面接觸,據以使該設備形成可移動,而可方便省力進行推移。By the way, with the rise of the industrial revolution in modern times, more and more equipment needs to be moved, and the application of casters has become more and more extensive. All walks of life are almost inseparable from casters. The casters are installed in equipment (such as carts, The bottom of the transport trolley, etc., by the casters contacting the ground, the equipment can be moved so that it can be moved easily and effortlessly.
一般腳輪通常未裝設有避震元件,因而移動設備若遇到顛簸地面時,不僅會讓承載的物品受到震動,甚至會造成承載的物品掉落,而很容易致使物品毁損。Generally, casters are usually not equipped with shock-absorbing components. Therefore, if the mobile device encounters a bumpy ground, it will not only cause the carried objects to be shaken, but also cause the carried objects to fall, which can easily cause damage to the objects.
於是有業者開發出習知具有避震功能的腳輪,其係於一組接座下端設置一輪座,該輪座樞設一輪體,該組接座中心部位設置一彈簧槽以供裝設一彈簧,藉由該彈簧達到避震效果。然而,因受到空間的限制,使得所裝設的彈簧尺寸與規格有限,以致彈簧的外徑與線徑皆必需相對縮小,方能順利安裝於彈簧槽中,故往往因彈簧的彈力不足,大幅降低所能提供的避震效果,甚至因彈簧過度壓縮而無法適時提供避震的功效,此外,該腳輪為可360度旋轉之活動腳輪時,常因重力超過組接座及輪座的負荷而造成變形,導致腳輪轉動不順暢,無法順利轉換方向,再者,其剎車結構複雜,組成構件多,對於製造者而言,其過多之構件將導致製造成本提高,且組裝上亦相對耗時耗力,對於消費者而言,其過多之構件不僅導致構件易損壞,使用壽命短,更會使得後續維修與更換費用增加。Therefore, some industry has developed a conventional caster with shock-absorbing function. A wheel seat is arranged at the lower end of a set of sockets, the wheel seat is pivoted with a wheel body, and the center of the set of sockets is provided with a spring groove for installing a spring. , The shock-absorbing effect is achieved by the spring. However, due to space constraints, the size and specifications of the installed spring are limited, so that the outer diameter and wire diameter of the spring must be relatively reduced in order to be installed in the spring groove smoothly. Therefore, the spring force is often insufficient. Reduce the shock-absorbing effect that can be provided, and even the effect of shock-absorbing cannot be provided in a timely manner due to the excessive compression of the spring. In addition, when the caster is a movable caster that can rotate 360 degrees, it is often caused by gravity exceeding the load of the assembly seat and the wheel seat. It causes deformation, causing the casters to not rotate smoothly and cannot change directions smoothly. Furthermore, the brake structure is complicated and there are many components. For the manufacturer, too many components will increase the manufacturing cost and the assembly will be relatively time-consuming. For consumers, too many components will not only cause components to be easily damaged and have a short service life, but also increase subsequent maintenance and replacement costs.
本發明人有鑑於習知具有避震功能的腳輪具有上述缺點,是以乃思及創作的意念,經多方探討與試作樣品試驗,及多次修正改良後,遂推出本發明。In view of the above-mentioned shortcomings of the conventional casters with shock-absorbing function, the inventor of the present invention is based on the idea of thinking and creation.
