A gear drive mechanism for downsizing office products, which can be easily disassembled, by thinning the gear drive mechanism. The gear drive mechanism drives a plurality of shafts cantilevered from a base plate attached within a label writer, wherein gears are fit on the shafts, and are engaged with each other, with specific shafts used as drive shafts. The gear drive mechanism comprises a groove formed around an end of at least one of the driven shafts other than the specific shafts, a ring-shaped washer having a slit in a direction of a diameter fit in the groove as a gear removal preventive and a recessed portion provided to a side surface of the gear throughout the washer.

A generally C shaped power tool handle has two ends for releasably engaging the power tool housing, with a gripping portion between the ends. One of the handle ends has a release lever, while the other of the ends has an attachment arm. The release lever has an actuating end operable to detach the handle from the tool housing. Additional power tool handle embodiments are directed to a tool handle that has a gripping layer and a storage compartment in the handle, with a pliable lip in the handle for resisting movement of stored tools.

An anti-theft device secures a removable body part, such as a viewing unit, to a microscope stand. The device is intended to replace a common thumbscrew used to fix the location of a removable body part in a corresponding guide of the microscope stand, and comprises a housing threaded into a tapped hole in the stand for carrying a plunger and a driver both movable within an axial passageway in the housing. The driver is threadably adjustable by hand between driving and non-driving positions with respect to the plunger, and the plunger has a limited range of motion so that it may retract enough to allow the removable body part to be adjusted within the guide but not enough to allow the body part to be removed from the guide when the driver is in a non-driving position. The housing is tightened onto the microscope body by a tool such as a wrench, and the driver is held captive by a snap ring fitting within an internal groove near a trailing end of the housing.

An anchoring biscuit device for joining three boards. It includes, (a) a first substantially flat horizontal top element having a generally biscuit-shaped configuration, (b) at least one substantially vertical support member attached to the underside of the top element and extending downwardly therefrom for a predetermined length for joinder of two adjacent boards which have been pre-cut with biscuit receiving slots, and, (c) an attachment orifice located at least on the top element for attachment of the anchoring biscuit device to a support board for anchoring and support of the two adjacent boards. In one preferred embodiment, a top bevel is included at the orifice to permit angled screwing at positions other than vertical positions. In other embodiments, the screw orifice will have an oval or elongated shape to likewise enable screwing at angles other than vertical. In yet another preferred embodiment, the orifice will both be beveled and elongated.

Self aligning, blind mating connector bodies are provided for connecting to mating connector bodies. One embodiment of the connector body has an annular housing with two slots disposed 180 degrees apart. An inner body has two dowel pins disposed at locations corresponding to the slots in the annular housing. A compliant O-ring is disposed between and is resiliently coupled to the inner body and the annular housing. The inner body is free to rotate relative to the annular housing about an axis defined by the dowel pins to provide single axis gimbal motion. Another embodiment of the connector body has an annular housing with two holes disposed 180 degrees apart. An inner body has two dowel pins disposed at locations corresponding to the holes in the annular housing. An external housing ring is connected to the annular housing using a second pair of dowel pins located 180 degrees apart that are disposed at 90 degrees with respect to the first set of dowel pins. In this embodiment, the inner body is free to rotate relative to the annular housing about an axis defined by the first pair of dowel pins, and the annular housing is free to rotate relative to the external housing ring about an axis defined by the second pair of dowel pins, thus providing two axis, dual gimbal motion that allows nutation. In both instances, a pair of openings is provided in the inner body to engage a mating pair of guide pins on the mating connector body.

There is shown a reformable handle (10) having an air pump (12), partially surrounded by a covering (13) so as to define a chamber (17) which contains a mass of filler material (18). The handle may be reformed into another configuration by a person firmly grasping the handle (10) so as to deform the covering (13) to conform with the person's grip and evacuating the air from within the chamber (17). The removal of air from within the chamber causes the covering to constrict about the filler material thereby locking the filler material in place. The handle may later be reconfigured by actuating a pressure release valve (44) which allows the return of air into the chamber. Once air is returned the filler material may be reconfigured and the pump actuated again to re-evacuate the chamber and once again reform the handle.

A tooless electrical connector includes a housing having a bore with a groove disposed on an inside surface of the bore with the groove establishing a shoulder between a groove bottom and a bore inside surface. A flat spring is provided and disposed in the groove for defining a spring cavity between the flat spring and the shoulder and a circular canted coil spring is disposed in the spring cavity. A pin having a circumferential groove is provided for receiving the coil spring upon insertion of the pin into the bore and a plurality of primary radial fingers formed in the flat spring retain the coil spring in the cavity before insertion of the pin. A plurality of secondary radial fingers formed in the flat spring prevent axial movement between the housing and the pin with the coil spring within the pin groove.

A quick disconnect tool apparatus for permitting a user to utilize a single pole member in conjunction with a variety of yard tools. The quick disconnect tool apparatus includes an elongate pole member having a uniquely shaped aperture. Inside the aperture are bearing members surrounded by a sliding sleeve member designed to position the bearing members inwardly and outwardly with respect to the longitudinal axis of the pole. Tool members having a tool coupler with a groove are insertable into the aperture and are releasably secured when the bearing members engage the groove.
