A latch mechanism for a cabinet having a drawer slideably disposed therein and moveable between opened and closed positions. The drawer has an elongated drawer pull having an elongated latch member that is slideably disposed under the drawer pull for longitudinal sliding between latching and unlatching positions. A latch is integrally disposed on one end of the latch member and has a latch surface. A protrusion having a protrusion surface is coupled to the cabinet and disposed in a position to be in abutting relationship with the latch when the drawer is in the closed position and the latch member is in the latching position and being in non-abutting relationship when the latch member is in the unlatching position. A spring is integrally provided on the latch member and is connectable to the drawer for biasing the latch member to the latching position.

A multiple-use battery pack system includes a battery pack housing enclosing a lead-acid battery and a post portion projecting from the housing and adapted to be plugged into a cavity in an associated cordless power hand tool. First terminals on the post portion connect the battery to the tool circuitry when the post portion is plugged into the tool. When used for powering other loads, the post portion is plugged into a receptacle in an adapter housing, in which position either the first terminals or, alternatively, second terminals on the battery pack housing connect the battery to jumper cables on the adapter housing. Latch mechanisms on the battery pack housing cooperate with keepers on the associated hand tool for latching the battery pack in place thereon.

A hand tool has an elongated shank with a handle at one end and a bit holder at the other end, the bit holder including a cylindrical body having a distal end surface and an axis, the body having an axial bore formed in the end surface of non-circular transverse cross section and terminating at an inner end surface. A neodymium permanent magnet is freely received in the bore and retained against the inner end surface by a thin circular retainer, formed of metal or plastic, which is interference-fitted in the bore. Both flat, disk-like and concave, bowl-shaped retainers are disclosed. A shock-absorbing cushion may be disposed between the magnet and the inner end surface of the bore. A bit formed of magnetizable material is mateably received in a socket portion of the bore and retained in place by the magnet. The portion of the bore receiving the magnet may have a different cross section from the socket portion. The magnet may be disposed in an encapsulation which interference fits in the bore.

A socket tool has an elongated body with driving and driven inserts, respectively, embedded in the opposite ends thereof, the inserts being flush with or recessed inwardly from the ends of the body. The inserts may be knurled around all or a portion of the outer surfaces thereof. Metal or non-metallic annular reinforcing members encircle at least one of the inserts. In one embodiment the reinforcement is a non-metallic sleeve which encircles the body along its entire length, and which may have end flanges overlapping the ends of the body. In other embodiments the reinforcement is entirely embedded in the body and in contact with the inner end surface and/or the peripheral side surface of at least one insert. In one embodiment the reinforcement extends from the insert to the outer surface of the body.

An adjustable tool extender includes a sleeve defining a receptacle and an extension member having a first end and a second end, wherein the second end defines a cavity and is slidable within the receptacle of the sleeve. The extender also includes a bias member seated in the receptacle and an end disposed in the cavity for biasing the extension member outwardly from the sleeve to a fully extended position.

A tool for moving two members relative to each other, such as narrow and wide tangs of an elastic clamp, includes first and second bodies formed substantially identically and operably coupled to each other in spaced, opposing relation, each of the bodies have a substantially lateral channel defining inner back, bottom and front walls therein. Each back wall includes a recess sized and shaped to cooperatively engage the narrow tang of the elastic clamp, when the narrow tang is received in the channel, to substantially retain the lateral position of the narrow tang relative to the body. Each front wall includes an opening for engaging the outward projection of the wide tang when the wide tang is received in the channel, thereby substantially retaining the lateral position of the wide tang relative to the body.

A ratchet wrench is provided having a flexible ring forming the head where the flexible ring may have serrations on its inner surface and forms a free end having a pawl thereon. The flexible ring is formed as one piece with the handle of the wrench. Upon tightening, the flexible ring will tighten down on a fastener and upon a non-tightening rotation, the pawl will ratchet against the corners of the fastener according to the self energizing geometry of the wrench where an arc is provided on a shoe of the handle which is eccentric to the arc of the flexible ring. In an embodiment, a gear insert is provided within the flexible ring for engagement with the fastener, torquing and ratcheting of the flexible ring being relative to the gear insert. In an embodiment, the a insert may be provided that has a substantially smooth outer surface including circumferential engagement features for engaging a substantially smooth facing surface of the flexible ring.

A composite box end wrench has a non-metallic body including a handle portion and at least one head portion which defines a fastener-receiving opening therethrough. The wrench includes strengthening and/or retaining structure which strengthens the head portion and can change the failure mode to confine wrench parts in the event of failure. In one embodiment each head portion has a fastener-engaging member insert molded therein along with a reinforcing plate which encircles the member and preferably extends slightly into the handle portion. The reinforcing structure could alternatively be a band extending the length of the wrench and encircling the fastener-engaging member (or members in a double-ended wrench). In a ratcheting version of the wrench the non-metallic body may be split lengthwise into two parts, each of which has reinforcing structure embedded therein, the fastener-engaging member being a ratchet gear which, along with an associated pawl, is disposed between the body parts. The parts may either confine or expose a peripheral portion of the gear, and the reinforcing structure encircles hub portions of the pawl and gear to the hold them together. The body parts may be secured together by various means, including pinning, ultrasonic welding and snap-fitting. The wrench body may be provided with an outer non-metallic sheath, in addition to or in lieu of the reinforcing structure, which sheath covers at least the handle portion of the body.
