Abstract
Abstract A knife handle employs a blade carrier having a planar blade support, a pair of parallel projecting flanges, and a laterally projecting lug for securing a blade in position to the carrier. A lateral retention tab extends from said carrier to capture an upper portion of a mounted blade for laterally securing said blade between said planar blade support and a bearing edge of the tab.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
136 words
A knife handle comprising: an elongated case having a forward blade opening and interiorly forming a pair of spaced guide means, and a blade carrier adapted for mounting a blade and slidably received in said guide means for selective longitudinal movement therealong between a retracted sheathed position and an extended unsheathed position wherein a blade mounted to said carrier extends through said blade opening to present a cutting edge, said blade carrier including a planar blade supporting portion, retainer means projecting laterally away from said blade supporting portion to removably transversely retain a mounted blade by engaging opposing peripheral edges of said blade and tab means to capture a mounted blade for lateral retention thereof in cooperation with said blade supporting portion by engagement of a portion of said blade adjacent one said opposing blade edge.
Claim 2
Dependent Claim
136 words
A knife handle comprising: an elongated case having a forward blade opening and interiorly forming a pair of spaced guide means, and a blade carrier adapted for mounting a blade and slidably received in said guide means for selective longitudinal movement therealong between a retracted sheathed position and an extended unsheathed position wherein a blade mounted to said carrier extends through said blade opening to present a cutting edge, said blade carrier including a planar blade supporting portion, retainer means projecting laterally away from said blade supporting portion to removably transversely retain a mounted blade by engaging opposing peripheral edges of said blade and tab means to capture a mounted blade for lateral retention thereof in cooperation with said blade supporting portion by engagement of a portion of said blade adjacent one said opposing blade edge.
Claim 3
Dependent Claim
37 words
The knife handle of claim 1 wherein said blade carrier further includes a lug means adapted for engagement with a notch at the top of a mounted blade for restraining the blade longitudinally relative to the carrier.
Claim 4
Dependent Claim
35 words
The knife handle of claim 1 wherein said tab means comprises a tab having a bearing edge which is laterally generally equidistantly spaced from said planar blade supporting portion for capturing a mounted blade therebetween.
Claim 5
Dependent Claim
29 words
The knife handle of claim 2 wherein said tab means extends generally forwardly and downwardly from an upper portion of said carrier and is disposed adjacent said lug means.
Claim 6
Dependent Claim
59 words
The knife handle of claim 1 further comprising a platform laterally projecting from said blade carrier at an upper portion thereof and a resilient finger extending rearwardly from said platform, said finger being adapted for manual actuation to selectively secure said carrier in a plurality of longitudinal positions within said case, said tab means integrally extending from said platform.
Claim 7
Dependent Claim
29 words
The knife handle of claim 3 wherein said bearing edge is spaced from said planar blade supporting portion a distance approximately commensurate with the thickness of a mounted blade.
Claim 8
Dependent Claim
195 words
A knife handle comprising: an elongated case having a forward blade opening and interiorly forming a pair of spaced guide means and a blade carrier adapted for mounting a blade and slidably received in said guide means for selective longitudinal movement therealong between a retracted sheathed position and an extended unsheathed position wherein a blade mounted to said carrier extends through said blade opening to present a cutting edge, said blade carrier being an integral structure comprising a planar blade support, a pair of generally laterally projecting parallel flanges for transversely retaining said blade, a generally laterally projecting lug for engagement with a notch at the top of a mounted blade to restrain the blade longitudinally relative to the carrier, a platform laterally projecting from an upper rear portion of said blade support, a resilient finger extending rearwardly from said platform and adapted for latching said carrier at a plurality of longitudinal positions within said case, and a tab extending at an acute angle from a forward portion of said platform, said tab being disposed rearwardly from said lug and having a bearing edge which is generally parallel to said planar support and spaced therefrom.
Claim 9
Dependent Claim
195 words
A knife handle comprising: an elongated case having a forward blade opening and interiorly forming a pair of spaced guide means and a blade carrier adapted for mounting a blade and slidably received in said guide means for selective longitudinal movement therealong between a retracted sheathed position and an extended unsheathed position wherein a blade mounted to said carrier extends through said blade opening to present a cutting edge, said blade carrier being an integral structure comprising a planar blade support, a pair of generally laterally projecting parallel flanges for transversely retaining said blade, a generally laterally projecting lug for engagement with a notch at the top of a mounted blade to restrain the blade longitudinally relative to the carrier, a platform laterally projecting from an upper rear portion of said blade support, a resilient finger extending rearwardly from said platform and adapted for latching said carrier at a plurality of longitudinal positions within said case, and a tab extending at an acute angle from a forward portion of said platform, said tab being disposed rearwardly from said lug and having a bearing edge which is generally parallel to said planar support and spaced therefrom.
Claim 10
Dependent Claim
35 words
The retractable knife handle of claim 7 wherein said blade carrier is adapted for seating a blade so that an upper portion of the blade is laterally captured between said tab and said planar support.
Claim 11
Dependent Claim
120 words
A knife handle comprising: an elongated case having a forward blade opening and a blade carrier adjacent said opening and adapted for mounting a blade so that said mounted blade extends through said blade opening to present a cutting edge, said blade carrier including a planar blade supporting portion, retainer means projecting laterally away from said blade supporting portion to removably transversely retain a mounted blade by engaging opposing peripheral edges of said blade, lug means to restrain a mounted blade longitudinally relative to the carrier and tab means adapted to capture a mounted blade for lateral retention thereof in cooperation with said blade supporting portion by engagement of a portion of said blade adjacent one said opposing blade edge.
Claim 12
Dependent Claim
120 words
A knife handle comprising: an elongated case having a forward blade opening and a blade carrier adjacent said opening and adapted for mounting a blade so that said mounted blade extends through said blade opening to present a cutting edge, said blade carrier including a planar blade supporting portion, retainer means projecting laterally away from said blade supporting portion to removably transversely retain a mounted blade by engaging opposing peripheral edges of said blade, lug means to restrain a mounted blade longitudinally relative to the carrier and tab means adapted to capture a mounted blade for lateral retention thereof in cooperation with said blade supporting portion by engagement of a portion of said blade adjacent one said opposing blade edge.
Claim 13
Dependent Claim
35 words
The knife handle of claim 9 wherein said tab means comprises a tab having a bearing edge which is laterally generally equidistantly spaced from said planar blade supporting portion for capturing a mounted blade therebetween.
Claim 14
Dependent Claim
32 words
The knife handle of claim 10 wherein said retainer means comprises a pair of parallel upper and lower flanges and said tab means extends generally forwardly and downwardly toward a lower flange.
