摘要： A brake-equipped swivel caster comprises a movable pin allowed to move up and down and normally retained in its uppermost position by an elastic member, and a bifurcated brake member including two downward-extending brake pieces, arranged with its top adjacent to the lower end of the movable pin and rotatably suspended by a horizontal shaft fitted to a tired-wheel support leg at a position off the axis of the movable pin. The brake member is subjected to the force of an elastic member tending to cause the brake member to turn in a direction away from the opposite lateral rim edges of a tired wheel, and is thereby retained in a non-braking condition. When the movable pin pushed down a specified distance pushes on the top of the brake member, the brake member turns so that the two brake pieces are pressed against the opposite lateral rim edges.

摘要翻译： 一种制动装置的旋转脚轮包括允许上下移动并通常由弹性构件保持在其最高位置的可动销，以及包括两个向下延伸的制动片的分叉制动构件，其布置成其顶部邻近下端 的可动销，并且在与可动销的轴线相离的位置处由安装在疲劳轮支撑腿上的水平轴可旋转地悬挂。 制动构件承受弹性构件的力，倾向于使制动构件沿远离轮胎的相对侧边缘的方向转动，并因此保持在非制动状态。 当可动销按压指定距离推动制动构件的顶部时，制动构件转动，使得两个制动片压靠在相对的侧边缘上。

摘要： A brake system for a wheelbarrow includes a plurality of elongate mounting brackets having opposed end portions connected to the frame of the wheelbarrow and an axle passing through the wheel, respectively, so that the plurality of mounting brackets become disposed on opposite sides of the wheel. The brake system further includes a plurality of levers including first end portions pivotally connected to the plurality of mounting brackets, respectively. The plurality of levers further include second end portions disposed rearwardly from the first end portions, respectively. A plurality of brake pads are connected to the plurality of levers and extend inwardly towards opposed sides of the wheel, respectively. A brake handle is connected to the frame and a cable mechanism cooperates with the brake handle for causing the plurality of brake pads to engage and disengage the wheel as the plurality of brake levers are pivoted outwardly and inwardly, respectively.

摘要： A wheelchair is disclosed that includes a seat, a pair of wheels, a detection part indicating the presence or absence of a user on the seat, electric brake units switching between applying braking forces to and releasing braking forces from the wheels based on control signals, and a control part connected to the detection part and the electric brake units and outputting the control signals to the electric brake units. The control signals include a first control signal causing the braking forces by the electric brake units to be applied to the wheels and a second control signal causing the braking forces by the electric brake units to be released therefrom. The first control signal is output when the detection part indicates the absence of the user on the seat, and the second control signal is output when the detection part indicates the presence of the user on the seat.

摘要： Fold flat walking or jogging strollers, as well as various fold flat cargo carrier devices are disclosed, which include at least three wheels which may have pivoting wheel support units and alternative foldable support frame embodiments are disclosed. The wheel support units include, in various embodiments, simple manually manipulable methods to latch each wheel in the operative or stowed flat positions, which effectively allows the device to fold to a flat profile without any part or wheel being detached. Associated innovations include a unique forward wheel folding system, a pivoting or floating transverse axle replicating unit (nullfalse axlenull), which pivots and latches to replicate a typical fixed wheel axle, but conveniently pivots to a fold flat stowed position. The innovations may also be applied to miscellaneous other types of wheeled carrier devices besides strollers, such as gurneys, golf bag carriers, and hunting game carriers as several examples, and also parking brake and alternative latch release methods are disclosed.

摘要： An auxiliary wheelchair braking apparatus includes a bracket adapted to be affixed to the frame of the wheelchair proximate each primary wheel thereof and utilizes caliper type braking device disposed on the bracket, one arm of the calipers being disposed on either side of the primary wheel. Activating levers are disposed proximate the backrest of the wheelchair for easy access by the elbows of the person making use thereof. Each of the activating levers are operatively coupled to the braking device for activation thereof. Pressure exerted on the activating levers forces the braking device to come into contact with the primary wheels responsive to the amount of pressure exerted on the activating lever.
