20080217115 | Brake Device for Pushcart - A brake device for a pushcart includes a main movable member disposed movably within a main seat, an auxiliary movable member disposed movably within an auxiliary seat, and a connecting member interconnecting the main and auxiliary movable members. The main movable member is biased to an upper limit position, and is movable to a lower limit position so as to engage a main brake pin with a groove in a main pin-engaging member that is connected fixedly to one wheel. Hence, the connecting member moves the auxiliary movable member from a first position to a second position so as to engage an auxiliary brake pin with a groove in an auxiliary pin-engaging member that is connected fixedly to another wheel. As a result, the wheels are locked. | 09-11-2008 |

20090078511 | Brake Mechanism for a Caster Wheel on a Offset Rotary Mower - A brake mechanism for a caster wheel(s) on an offset rotary mower apparatus wherein a hydraulic line or electric cable is connected at one end to the brake mechanism and at the other end to the tractor for remote control operation of the brake mechanism. The brake mechanism which is attached about the vertical caster axis of the caster wheel allows the caster wheel(s) to temporarily become a fixed wheel(s) when needed, assisting in reducing side draft load on the towing vehicle when the offset rotary mower apparatus is on steep slopes and enabling the offset rotary mower apparatus to be backed-up on the side slope of a ditch. | 03-26-2009 |
20090139804 | Cart Braking Device - A cart braking device includes a swivel unit, a shaft unit and a braking unit which has a central shaft, an orientation member, a braking member and a base. The central shaft is coupled with the orientation member and has an elastic piece for moving the central shaft upward. A bottom of the orientation member has an orientation gear and a top of the braking member has a fixation gear corresponding to the orientation gear. The braking member is disposed in the base and includes two braking pads. An elastic member is disposed between the base and the braking member, and can move the braking member away from the base. When the braking pads are pressed against the wheel, the cart braking device stops the rotation of the wheel. When the orientation gear is engaged with the fixation gear, the cart braking device prevents the wheel from changing direction. | 06-04-2009 |
20100044164 | Braking System for a Stroller - A braking system for a stroller includes: a brake pedal positioned near a first rear wheel of the stroller; a braking cam operationally coupled to the brake pedal and rotatable around a pivot point from a first position to a second position; and a brake lever having a first end configured to contact the braking cam when the braking cam is in the second position, and a second end having a plurality of teeth configured to engage at least one gear driven by the first rear wheel of the stroller when the braking cam is in the second position. A depression of the brake pedal causes the braking cam to rotate around the pivot point from the first position to the second position, thereby causing the teeth of the brake lever to engage the at least one gear to prevent rotation of the first rear wheel. | 02-25-2010 |
20100122875 | Braking system for front caster wheels of a self-propelled vehicle - A ride-on, self-propelled vehicle having front caster wheels, such as a zero-turn mower, includes a front brake system. The actuating power for the front brake pass through a spindle supporting the front caster wheel. In a preferred embodiment, a center shaft of each spindle or a concentric outer ring of a sleeve of each spindle passes a force from a brake actuator to a brake for the respective caster wheel. Actuation of the brake actuator moves a member into frictional contact with a portion of the front wheel or an object attached to the front wheel to applying a braking force. | 05-20-2010 |
20100252371 | BRAKING ARRANGEMENTS AND METHODS - A braking arrangement for a wheel of a shopping cart or the like includes a braking arm moveable about an axis from a free running position to a braking position when the wheel is lifted from the ground.

20110120815 | Braking System for Patient Support - An assembly controls brakes on beds for use in healthcare facilities. The bed comprises at least one caster device supporting a base frame in relation to a supporting surface. The caster device has a caster brake. A brake control assembly is operatively engageable with the caster brake to engage the caster brake. The brake control assembly comprises a sensor for sensing a status condition of the caster brake. A controller is connected to the sensor. The controller causes engagement of the caster brake when the sensor senses the status condition for a predetermined period of time. | 05-26-2011 |
20120085595 | CENTRAL CONTROL BRAKING SYSTEM - A central control braking system includes: a pedestal; at least one caster mounted at a bottom portion of the pedestal; a brake transmission shaft for controlling the caster; a plate girder movably connected to the pedestal; a pedal fixed to the plate girder; and a reversing rotary assembly connecting the plate girder and the brake transmission shaft, wherein the reversing rotary assembly enables the brake transmission shaft to rotate in reverse under the control of the pedal. | 04-12-2012 |
20120160617 | BAGGAGE CASTER LOCK DEVICE - A baggage lock device to halt rotation of caster wheels as the handle is retracted, and allow the wheels to move as the handle is pulled out. The device has a receptacle with a handle extendable to be pulled put. A wheel halting mechanism has a traction cord inhibiting wheel rotation by a force pressed against the wheel as operation of an operation mechanism is transmitted via a pulling force transmission mechanism having a pulled wire, a brake pad, a linking member, and means for restoring the position of the operated elements.”. | 06-28-2012 |
20120199423 | BRAKE PEDAL MECHANISM FOR HOSPITAL BED - A brake system for a patient support apparatus having a base frame includes pedals positioned to be moved by a user to move a brake and a mechanism positioned to coordinate movement of the pedals so that downward movement of one pedal positioned adjacent the head end of the base causes movement of the mechanism in a first direction and downward movement of another of the pedals causes movement of the mechanism in a second direction, opposite the first direction. | 08-09-2012 |
20140083803 | CENTRAL CONTROL BRAKING SYSTEM - A central control braking system includes: a pedestal; at least one caster mounted at a bottom portion of the pedestal; a brake transmission shaft for controlling the caster; a plate girder movably connected to the pedestal; a pedal fixed to the plate girder; and a reversing rotary assembly connecting the plate girder and the brake transmission shaft, wherein the reversing rotary assembly enables the brake transmission shaft to rotate in reverse under the control of the pedal. | 03-27-2014 |
20140102834 | Braking Mechanism - A braking mechanism operably engaging at least one wheel where the mechanism is capable of transitioning the at least one wheel between unlocked and locked states is provided. The braking mechanism includes a flipper and a cam. The flipper is adapted to move in X, Y and Z-directions and includes a discontinuous track having an open slot portion and a surface path portion. The open slot portion includes a home position and an engaged position. The cam includes a pin which cooperatively moves along the discontinuous track.

20160136997 | Brake Mechanism for Mobile Currency Vaults - A brake mechanism for mobile currency vaults includes a braking gear coupled to a vault wheel to govern rotational movement of the wheel. An interference tab is biased to an interference fit between the gear's teeth to stop rotation of the wheel. Disengaging the gear is controlled near the handles of the vault, which also provide steering control, so that users must actively disengage the interference tab to allow the wheel to rotate. The brake mechanism also has a brake release for locking in a disengaged or engaged position. The brake release spans the mobile currency vault from a front wheel to a rear handle. The brake release also has a control, preferably at a rear end of the vault, requiring activation by a key and an indicator pusher. | 05-19-2016 |
