Abstract
Abstract A handle (10) is provided for blades, and particularly surgical blades, which allows simple insertion sequentially of a plurality of blades, and closure to a locked position of the blade, upon insertion. The two parts of the handle (10) pivot relative to one another (12,14) in the same longitudinal plane around a pivot (24,29) positioned adjacent the blad position. This allows a relatively long handle portion for gripping the device for ejecting the blade, using the thumb or finger of the same hand for opening the handle (10) for ejection single handedly. The gripping portion (32,34) of the handle (10) has adjacent to the blade portion thereof a boss (20) which conforms to the opening in the blade tang. Closure causes the movable portion of the handle (10) to cover the boss (20) and the blade tang in a wedging action preventing movement of the blade relative to the handle (10) in closed position. When opening, the user pushes the movable portion (14) of the handle (10) open while holding the blade and boss (20) of the fixed handle portion (12) facing downward so that the blade falls out of the device, without any touching or movement of any kind, into a sharps collector. <IMAGE>

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
226 words
A blade holder, comprising: (a) an elongated flat fixed body portion; (b) a blade receiving area at one end of said elongated fixed body portion; (c) a handle gripping area at the other end of said fixed body portion opposite said blade receiving area; (d) a pivot pin on said flat fixed body intermediate the ends thereof adjacent said blade receiving area; (e) the axis of said pivot pin being perpendicular to said flat fixed body portion; (f) an integral elongated boss on the surface of said blade receiving area for receiving the tang of a blade, said boss being the same shape as the opening in the tang of a blade to be received thereover; (g) an abutment extending from each end of said integral elongated boss; (h) an elongated flat rotatable body portion having a pivot axis intermediate the ends thereof (i) said rotatable body portion rotatable around said pivot axis on said pivot pin from an open position for receiving a blade in said blade receiving area to a closed position locking a blade tank in said blade receiving area; (j) said abutments for engaging the cooperating opposed surfaces of said elongated rotatable body portion; and (k) cooperating locking means on said flat fixed body portion and said rotatable body portion for locking the tang of a blade in said blade receiving area.
Claim 2
Dependent Claim
226 words
A blade holder, comprising: (a) an elongated flat fixed body portion; (b) a blade receiving area at one end of said elongated fixed body portion; (c) a handle gripping area at the other end of said fixed body portion opposite said blade receiving area; (d) a pivot pin on said flat fixed body intermediate the ends thereof adjacent said blade receiving area; (e) the axis of said pivot pin being perpendicular to said flat fixed body portion; (f) an integral elongated boss on the surface of said blade receiving area for receiving the tang of a blade, said boss being the same shape as the opening in the tang of a blade to be received thereover; (g) an abutment extending from each end of said integral elongated boss; (h) an elongated flat rotatable body portion having a pivot axis intermediate the ends thereof (i) said rotatable body portion rotatable around said pivot axis on said pivot pin from an open position for receiving a blade in said blade receiving area to a closed position locking a blade tank in said blade receiving area; (j) said abutments for engaging the cooperating opposed surfaces of said elongated rotatable body portion; and (k) cooperating locking means on said flat fixed body portion and said rotatable body portion for locking the tang of a blade in said blade receiving area.
Claim 3
Dependent Claim
29 words
The blade holder of claim 1, further comprising (a) frictional gripping surfaces on each side of said fixed and rotatable body portions for holding said blade holder during use.
Claim 4
Dependent Claim
59 words
The blade holder of claim 1, wherein (a) the opposed surfaces of said elongated flat fixed portion and said elongated flat rotatable portion are bowed toward each other in said blade receiving area; (b) whereby in said locked position the said opposed bowed surfaces serve to hold a blade therein fixed against any movement relative to said blade holder.
Claim 5
Dependent Claim
268 words
A blade holder, comprising (a) an elongated flat fixed body portion; (b) a blade receiving area at one end of said elongated flat fixed body portion; (c) a handle gripping area at the other end of said flat fixed body portion opposite said blade receiving area; (d) a pivot pin on said flat fixed body portion intermediate the ends thereof adjacent said blade receiving area; (e) the axis of said pivot pin being perpendicular to said flat fixed body portion; (f) a boss on the surface of said blade receiving area for receiving the tang of a blade, said boss being the same shape as the opening in the tang of a blade to be received thereover; (g) an elongated flat rotatable body portion having a pivot axis intermediate the ends thereof; (h) said rotatable body portion rotatable around said pivot axis on said pivot pin from an open position for receiving a blade in said blade receiving area to a closed position locking a blade tang in said blade receiving area; and (i) cooperating locking means on said flat fixed body portion and said rotatable body portion for locking the tang of a blade in said blade receiving area, said cooperating locking means including (1) a curved slot on said elongated fixed body portion; (2) an indentation at the end of said curved slot; (3) a curved extension on said rotatable body portion at the other end thereof opposite said blade receiving area; and (4) a locking abutment on the end of said curved extension for extending into said indentation at this end of said curved slot.
Claim 6
Dependent Claim
268 words
A blade holder, comprising (a) an elongated flat fixed body portion; (b) a blade receiving area at one end of said elongated flat fixed body portion; (c) a handle gripping area at the other end of said flat fixed body portion opposite said blade receiving area; (d) a pivot pin on said flat fixed body portion intermediate the ends thereof adjacent said blade receiving area; (e) the axis of said pivot pin being perpendicular to said flat fixed body portion; (f) a boss on the surface of said blade receiving area for receiving the tang of a blade, said boss being the same shape as the opening in the tang of a blade to be received thereover; (g) an elongated flat rotatable body portion having a pivot axis intermediate the ends thereof; (h) said rotatable body portion rotatable around said pivot axis on said pivot pin from an open position for receiving a blade in said blade receiving area to a closed position locking a blade tang in said blade receiving area; and (i) cooperating locking means on said flat fixed body portion and said rotatable body portion for locking the tang of a blade in said blade receiving area, said cooperating locking means including (1) a curved slot on said elongated fixed body portion; (2) an indentation at the end of said curved slot; (3) a curved extension on said rotatable body portion at the other end thereof opposite said blade receiving area; and (4) a locking abutment on the end of said curved extension for extending into said indentation at this end of said curved slot.
