Abstract

现有上支撑点与滚轮轴不在一垂线上的用于家具或推车等的脚轮,虽可以有制动作用,但存在一些缺点而易发生故障。本实用新型为用一个与地面接触的滚动圆球、固定在家具等上的支座,并在二者间装有几个滚珠的、有制动机构的脚轮装置。圆球可用金属、低弹性塑料或夹有玻璃纤维的“玻璃钢”制成。由于有S型的导向槽使制动轫块上升然后定位,而使圆球制动。

Description

本实用新型为一种用于家具或推车等的脚轮。
现有的上支撑点与滚轮轴不在一垂直线上的有轴脚轮,是靠几个脚轮分别处于不同所运动方向而起制动作用。其缺点是与家具连接点受弯力、水平轴受力大而易出现故障。由滚球、固定在家具上的支座及二者之间的不少于三个滚珠组成的无轴脚轮,如专利CNZL87202299等,则无制动功能。
本实用新型的目的,是使滚动球式脚轮能在家具等需定位时制动。
图1是实用新型的实施例。
图2是制动型脚轮的支座(4)上的S型导向槽(9)的详图。
如图1所示:滚动球式脚轮,由与地面(2)接触的园球(1)、滚珠(3)及支座(4)组成,其特征是:有一个由橡胶制成的轫块(6)及使用其压紧或离开园球(1)的制动机构。
如图2所示:柄(7)上的销(8)可在槽(9)中运动,当下降到定位位置(10)时为制动状态,上升到位置(11)时脚轮可滚动。
与现有技术相比,本实用新型能在必要时使脚轮制动。
