| 20120084983 | DRIVE SYSTEM FOR ROTARY DRIVEN HAIR CLIPPERS - A hair cutting device has a stationary blade, a reciprocating blade and a rotary motor. The reciprocating blade has a cam follower in contact with the top surface of the reciprocating blade, and a slot for receiving a cam. The cam is secured to the motor shaft on one end, and has an offset pin on the other end. The offset pin fits in the cam follower slot so that when the motor rotates the cam through rotational cycles, the offset pin oscillates the reciprocating blade back and forth. The offset pin extends at least to or through the plane of the reciprocating blade for the entire rotational cycle of the offset pin, which reduces torque and twisting of the reciprocating blade. | 04-12-2012 |
| 20120030950 | VIBRATOR MOTOR - A vibrator motor in a hair clipper has a stationary piece and a moving piece. The stationary piece has a primary leg and at least one secondary leg. The primary leg fits through an opening in a coil. A flange is then press fit onto the leg so that the coil is captured on the primary leg. The flange provides a magnetic pole face that is larger than the opening in the coil, which increases the efficiency of the motor. The flange is press fit in a single operation by pressing a primary prong into a primary socket, and pressing two secondary prongs into secondary sockets. The secondary prongs are guided inwardly as they enter the secondary sockets, which closes the primary socket around the primary prong. A drive arm is secured to an arm of the moving piece. The arm is angled in relation to the drive arm to put even pressure on the moving blade in the hair clipper. | 02-09-2012 |
| 20110146084 | ATTACHMENT COMB FOR A HAIR CLIPPER - An attachment comb for a hair clipper includes a base portion constructed and arranged for releasably engaging the hair clipper, and a plurality of teeth extending from the base portion, each of the teeth including a body portion defined between an upper peripheral edge and a lower peripheral edge, a proximal end adjacent the base portion and a distal end opposite thereof, wherein the body portion includes at least one formation for retaining hair. | 06-23-2011 |
| 20100017998 | MULTI-USE MOBILE VACUUM CART - A mobile vacuum cart includes a housing, a vacuum source in the housing, a dust box releasably engaged in the housing and in fluid communication with the vacuum source, an intake conduit in fluid communication with the dust box, wherein the housing accommodates reciprocal sliding action of the conduit between an engaged position in which the conduit locks the dust box in position and a release position in which disengagement of the conduit from the dust box enables removal of the dust box from the housing. | 01-28-2010 |
