| 20120054998 | BALL ACTUATED LOCK PIN - A lock pin assembly used for clamping two plates together, that have aligning bores for receiving the lock pin assembly. The lock pin assembly includes radially extending pins that can be forced outwardly from the center of a lock pin housing forming a part of the lock pin assembly. The actuator pins are forced outwardly and cooperate with a tapered surface on a bottom plate to create a clamping force relative to an end of the lock pin housing supportable on a top plate. The lock pin housing has cam tracks on an outer side thereof, and an actuator ring surrounds and supports the pin and carries cam followers sliding in the cam tracks. The cam tracks are made such that relative rotation of the lock pin housing and the actuator ring changes the axial location of the actuator ring along the housing. The actuator ring rests on the top plate and when the actuator pins are released so they can retract and the lock pin housing and the actuator ring are relatively rotated, the lock pin housing is raised relative to the two plates to aid in removing the lock pin assembly. | 03-08-2012 |
| 20120043711 | FIVE AXIS MACHINE VISE - A five axis vise includes two separated vise body portions that are supported on a machine tool table or other support that fixes the vise body portions in position. The vise body portions have jaws spaced up from the machine tool table sufficiently to permit machining five surfaces of a work piece held in the jaws. A vise screw is rotatably mounted in one of the vise body portions, and extends to the other vise body portion to actuate a movable jaw on the other vise body portion. The vise screw is threaded into a jaw nut that has a drive surface that engages and drives a driven surface on the movable jaw, with the drive and driven surfaces being inclined relative to the axis of force application to provide a downward force component on the movable jaw as it is tightened. The vise screw is an assembly of a threaded shank or shaft and a hub that is rotatably mounted in one of the body portions, with the threaded shank or shaft being locked in position in the hub. | 02-23-2012 |
| 20090075785 | BICYCLE TRAINER - A bicycle trainer is adapted for use with a bicycle. The trainer includes a base and a frame having spaced apart ends adapted to engage and support the bicycle. A pivoting assembly is joined to the frame of a central portion of the frame and to the base. The pivoting assembly allows movement between the frame and the base and includes a biasing mechanism that resists tilting of the frame relative to the base. The frame is supported only by the pivoting assembly. | 03-19-2009 |
