Filed:

Jul 5, 2000

Appl. No.:

09/610253

Inventors:

Raymond E. Davis - Garland TX

Assignee:

Adco Industries - Garland TX

International Classification:

B26B 108

US Classification:

30 2, 30162, 30335

Abstract:

A utility knife and various manufacturing methods for the utility knife. In one embodiment, the utility knife includes: (1) a body having a cutting face and (2) a blade-holding slide mounted for linear movement within the body and having a knife-holding head extendable through an opening in the cutting face. The opening has aparallel opposing sides that diverge toward a cutting direction of the utility knife. The knife-holding head has corresponding aparallel opposing sides that cooperate with the sides of the opening to cause a cutting force exerted on the knife-holding head to wedge the blade-holding slide within the opening and thereby stiffen the knife-holding head with respect to the body during operation of the utility knife. In one embodiment of the present invention, the blade-holding slide resiliently urges the knife-holding head to unwedge when the cutting force is removed therefrom.

Assignee:

Dallco Marketing, Inc. - Garland TX

International Classification:

B26B 2902

US Classification:

30 2, 30162, 30286, 30295, 30335

Abstract:

A deflectable safety shield extends transversely across a cutting plane in a protective guard position completely overlying the cutting edge of a utility knife. A portion of the shield extends over-center with respect to the cutting edge, thereby tending to hold the shield in the guard position in response to contact of the shield against the operator at the normal angle of engagement during follow-through that accompanies rapid slicing hand movements. The shield is resiliently biased for movement to the guard position by a torsion spring. An outwardly-turned flange portion of the shield provides an angularly offset leverage point for reacting the torsion spring when the operator desires to perform a cutting operation. The shield swings away from the cutting plane automatically in response to pressure engagement of the offset flange portion against the box surface, thus exposing the cutting edge.

International Classification:

B23P 11/00
B65C 7/00

US Classification:

2952501, 227 67

Abstract:

A protective assembly for a tag tool includes a shoe, a shoe spring coupled to the shoe, a tag spring, and a thimble. The shoe includes a shoe bore extending through a distal end of the shoe, where the shoe is adapted to attach to a tag tool having a tag tool needle extending from the tool. The tag spring is coupled to the shoe adjacent the shoe spring and distal ends of the shoe spring and tag spring define an opening to receive a product tag therebetween. The distal end of the tag spring and the shoe define a slot to receive a product material therebetween. The thimble is adapted to move through the shoe bore in response to a force applied to a distal end of the thimble and transmit at least a portion of the force to the tag spring and the shoe spring.

Assignee:

ADCO Industries—Technologies, L.P. - Dallas TX

International Classification:

B26B 1/08

US Classification:

30162, 30335

Abstract:

A utility cutter includes a housing, a blade and blade shuttle, a blade trigger, and a trigger lock. The blade and blade shuttle are enclosed within the housing in a retracted position. The blade is extended from the housing in an extended position. The blade trigger includes a cavity and is coupled to the housing. The blade shuttle is conveyed from the retracted position to the extended position when the blade trigger pivots from a rest position to an engaged position. The trigger lock includes a projection and is accessible at the exterior of the housing through the blade trigger. The trigger lock is coupled to the blade trigger and the projection is in contact with the stop pin when the blade shuttle is in the retracted position. The blade trigger is pivotable from the rest position to the engaged position when the projection is released from the stop pin.

Abstract:

A shelving system supporting consumer products includes a base structure, a plurality of vertical support members, side cross-members, and a mobile support shelf. The base structure includes two side base members and a front base member attached to each side base member to define a substantially U-shaped enclosure. Each vertical support member includes a base end and a top end and each support member is attached to the base structure at the base end. Each side cross-member is coupled between two vertical support members. The mobile support shelf includes a shelf frame adapted to fit within the U-shaped enclosure. The shelf frame includes wheels coupled to the shelf frame and a latch pin adapted to engage a slot in a proximate side base member as the shelf frame is inserted into the U-shaped enclosure. The mobile support shelf includes a shelf pivotally coupled to a topside of the shelf frame.

International Classification:

B26B 1/08

US Classification:

30162, 30335

Abstract:

A utility knife includes a handle body having sidewall portions defining a guide channel, a blade shuttle mounted for extension and retraction movement within the guide channel, and a hand-grip lever coupled to the handle body at a fulcrum for pivotal movement between an at-rest position in which the blade shuttle is in a non-use position, to an in-use position in which the blade shuttle is in an extended position. In the non-use position, a blade mounted on the blade shuttle is enclosed in the guide channel. In the extended position, a portion of the blade projects from the guide channel. The hand-grip lever is rotatably coupled to the blade shuttle through a transmission comprising a pin coupled to the lever such that a distance from the fulcrum to the pin stays substantially fixed as the lever pivots between the at-rest and in-use positions.
