In one of the loops the hard plastic material defines only a part of the loop, terminating in spaced ends which are fixed to a flexible and resilient portion which completes the loop. The other loop has projecting forwardly therefrom a hard plastic finger rest which extends along the handle portion and defines a channel receiving the handle portion of the one loop. Both loops have hard plastic buttons projecting therefrom which abut when the scissors are closed. The flexible and resilient portion of the one loop is formed of a soft, frictional material which also covers outer surfaces of the hard plastic portions of both loops and the finger rest.

Abstract: A hand-actuated scissors useable by an individual whose hands and fingers are weak or impaired and therefore experience difficulty in operating a conventional scissors. The scissors include a pair of blades whose cutting edges face each other, the blades being joined by a swivel pin whereby in an open state of the scissors the blades are angled with respect to each other. When the scissors are put into a closed state, the blades are then brought together to effect a cutting action. The handle sections of the blades which extend beyond the swivel pin are so shaped that in the open state the ends of these sections are widely spaced apart. Bridging the ends of the handle sections is a yoke defined by a saddle-shaped plate of resilient material forming a spring-loaded grip which normally maintain the scissors in an open state.

The handles each includes a peripheral rib for engaging with the peripheral grooves of the rings and for securing the rings to the handles.

Abstract: A pair of self-opening scissors or shears, or an attachment which can be used with conventionally designed scissors or shears, particularly of the kind used by barbers or the like. The invention uses a pair of inserts for the finger holes of the scissors, connected by a band of an elastic material which serves to provide a self-opening force. The inserts fit into the finger holes, simultaneously holding the elastic band and reducing the size of the finger holes for smaller hands. The self-opening finger inserts of the invention can be used with existing scissors, or built into new scissors at time of manufacture without requiring major redesign or changes in manufacture. The scissors with the invention will reduce repetitive motion injury while remaining conventional in shape and feel.

Abstract: Disclosed is a grip-enhancing device for a shaft handle which includes a grip portion generally coaxial with the shaft and sized to be grasped generally around its longitudinal axis by the palm and fingers of a user's hand. The grip-enhancing improvement comprises a rigid first portion extending substantially radially outwardly from the grip portion and presenting a surface positioned to bear against an edge of the user's hand. The surface has a cross-section which is spaced radially from and extends obliquely with respect to the longitudinal axis of the grip portion. A rigid second portion extends from the first portion in a direction oblique to the longitudinal axis of the grip portion and toward the user's wrist. The grip portion, the first portion and the second portion define a gap in which the user's hand is partially captured, thereby preventing axial and lateral slipping of the hand from the handle and reducing fatigue to the user.
