    • A manually movable trolley (1) which is nestable with like trolleys, including a frame (3), a loading platform (7) and two upwardly extending uprights (13) located at the rear (4) of the wheel frame (3) and carrying a pushing arrangement (14), wherein a brake device (16) is provided which is controllable by the pushing arrangement (14) and effective when the trolley (1) is not in use. A brake release device (20) is provided underneath the frame (3) close to each rear wheel (9), guided in a wheel housing (10), and release parts (25) each provided with an active surface (26) are arranged on the frame (3) and are adapted to deflect the two brake release devices (20) of the preceding trolley (1′) by means of their active surface (26) when two trolleys are nested.

    • A brake mechanism for a shopping cart able to brake an unattended cart while enabling manual release of the brakes for user control and automatic release of the brakes in response to telescoping joinder of the carts. Comprising the braking mechanism is a brake pad at the underside of a pair of vertically disposed brake rods displaceable for the pads to engage and disengage the caster wheels of the cart. A compressed coil spring on each brake rod biases the pad thereat toward engagement with the wheels. A transverse actuator bar adjacent the cart handle, when squeezed toward the cart handle, causes the brake rod to incur an upward camming and effect release of the brakes. At the same time, a second actuator bar resting on the swing seat of the cart and displaceable upwardly with the swing seat in response to telescoping of the carts is pivotally displaced upwardly in response to telescoping to raise the brake rods and release the brakes.
    • 一种用于购物车的制动机构,其能够制动无人值守的手推车,同时能够手动释放用于用户控制的制动器,并响应于推车的伸缩联接而自动释放制动器。 包括制动机构的是在一对垂直设置的制动杆的下侧处的制动衬块,其可移动以使垫接合和分离推车的脚轮。 每个制动杆上的压缩螺旋弹簧将其垫片偏压以与车轮接合。 与推车手柄相邻的横向致动器杆当朝向推车手柄挤压时,使制动杆产生向上的凸轮并且释放制动器。 同时,响应于推车的伸缩,搁置在推车的摆动座上并与摆动座一起向上移动的第二致动器杆响应于伸缩而向上枢转地移动以升高制动杆并释放制动器。

    • A braking system designed to be an integral part of a shopping cart. The braking system consists of a hand-operated brake that is normally engaged. The user disengages the braking system to move the shopping cart. The braking system is also disengaged when the shopping cart is nested with other shopping carts to allow multiple carts to be moved without the brakes being engaged. The mechanical link from the handle to the brake is enclosed within the frame to reduce potential damage to the mechanism. The mechanical link consists of a hand-activated handle that is pushed down to disengage the brake, and when the handle is not depressed, the handle raises by gravity and applies the brake.
    • 制动系统设计为购物车的组成部分。 制动系统由通常接合的手动制动器组成。 用户解除制动系统以移动购物车。 当购物车与其他购物车嵌套时,制动系统也被分离,以允许在没有制动器被接合的情况下移动多个推车。 从手柄到制动器的机械连接被封闭在框架内,以减少对机构的潜在损坏。 机械连杆由手动启动的手柄组成,其被推下以使制动器脱离,并且当手柄未被压下时,手柄通过重力升高并施加制动。
