20130111967 | PUNCH AND DIE SET - A punch and die set includes a die including two arms. The two arms and a bottom of the die define a die channel. A punch is sized to be received in the die channel. A rocker element is movably secured to the die. A reduced frictional element is movably secured to the rocker element. The rocker element is movably secured to the die so that the rocker element pivots relative to the die around a pivot point between a centerline of the die channel and at or inside a first of the arms. | 05-09-2013 |
20120233779 | LATCHING MOTION TRANSFER MECHANISM - Latching motion transfer arrangements may be used to raise an object up and out of the engagement with the ground or other support surface and to lower the object back onto the ground or other support surface. In one exemplary embodiment, the mechanism is caused to lift and latch by applying force in a first direction, a first time, and is caused to release and lower by applying force in the first direction, a second time. | 09-20-2012 |
20120223514 | WHEELCHAIR - A conveyance such as a wheelchair that includes a seat assembly and a chassis. The chassis comprises a central frame member disposed substantially along the centerline of the wheelchair. The central frame member includes portions for connecting to or supporting one or more front casters, a seat assembly, one or more drive wheel assemblies, an energy source (e.g., one or more batteries), rear anti-tip wheels, and/or at least one footplate. The central frame member is disposed substantially along the centerline of the wheelchair and structurally distributes of the weight of the seat assembly (and optionally the weight of the energy source) to the supporting drive wheels and casters. In this manner, a clean-looking, simple, and lightweight chassis structure is provided for a conveyance. | 09-06-2012 |
20120217713 | WHEELCHAIR SUSPENSION - A wheelchair includes a frame, a rear caster coupled to the frame, a drive wheel coupled to the frame, a front caster, and a pivoting assembly. The pivoting assembly couples the front caster to the frame such that upward movement of the front caster relative to the frame causes the front caster to move toward the drive wheel. | 08-30-2012 |
20120217070 | OBSTACLE TRAVERSING WHEELCHAIR - A wheelchair suspension is provided. The wheelchair suspension includes a frame, a front caster pivot arm, a drive assembly, and a rear caster. The front caster pivot arm is pivotally connected to the frame. The front caster is coupled to a front end of the front caster pivot arm. The drive assembly is pivotally connected to the front caster pivot arm. The drive assembly comprises a drive wheel and a motor that drives the drive wheel. Torquing of the drive wheel by the motor in a forward direction causes the drive assembly to pivot with respect to the front caster pivot arm such that the drive wheel moves forward toward the front caster and a distance between a support surface and the connection between of the drive assembly and the front caster pivot arm increases. | 08-30-2012 |
20120005828 | POWER AND CONTROL SYSTEM FOR BED - Embodiments of a power and signal distribution assembly for a bed having at least one power input port, at least one controller port, and at least one output port are described. The power input port receives a first DC voltage from a power supply and the power supply receiving an AC voltage and converting it to the first DC voltage. The controller port receives the first DC voltage and outputs at least one power control signal having the first DC voltage. The output port receives signals having the first DC voltage. The power and signal distribution assembly has a first location and the power supply has a second location different from the first location. In other embodiments, the power and signal distribution assembly is located on a frame of a bed and the power supply remote therefrom. Still further, one or more additional controller ports may also be provided. | 01-12-2012 |
