Abstract
Abstract A holder for knives or the like implements, serving to maintain them with their cutting edges in a protected enclosed position, and permitting ready selective insertion and removal of the knife, or the like from the holder. The holder is formed by a block member having an interior vertically extending channel therein defined by a vertically extending surface spaced from an inclined surface, with the lower end of the inclined surface closer to the vertically extending surface. A locking member is loosely positioned in said channel for sliding between said surfaces, and a stop member at the lower end of said channel limits the downward movement of said locking member to prevent its being wedged into a jammed position between said surfaces, whereby a knife or the like inserted into said channel will be engaged by said locking member against said vertical surface. The locking member is formed with a chamfered leading edge serving the twofold function of implementing insertion of the knife blade and permitting honing of the blade.

Total Claims: 7
Claim 1
Independent Claim
215 words
A holder for knives or the like articles, said holder comprising: a block member having an interior vertically extending channel therein, a vertically extending surface defining one wall of said channel, and an inclined surface spaced from said vertically extending surface defining the other wall of said channel, said inclined surface spaced apart further from said vertical surface at the top of said channel than at the bottom of said channel, said channel having a slot adjacent said vertical surface extending from top to bottom of said block, permitting insertion of a knife or the like into said channel; a locking member movably mounted in said channel between said inclined and vertical surfaces downwardly movable under the action of gravity in said channel towards said vertical surface, said locking member in the form of a right circular cylinder arranged with its axis perpendicular to the axis of said channel and formed with a chamfer at the end of said cylinder adjacent the slot in said channel; and a stop member at the lower end of said channel limiting the downward movement of said locking member at a lower limiting position providing clearance between the locking member and at least one of said surfaces of the channel whereby said locking member cannot jam in said channel.
Claim 2
Dependent Claim
215 words
A holder for knives or the like articles, said holder comprising: a block member having an interior vertically extending channel therein, a vertically extending surface defining one wall of said channel, and an inclined surface spaced from said vertically extending surface defining the other wall of said channel, said inclined surface spaced apart further from said vertical surface at the top of said channel than at the bottom of said channel, said channel having a slot adjacent said vertical surface extending from top to bottom of said block, permitting insertion of a knife or the like into said channel; a locking member movably mounted in said channel between said inclined and vertical surfaces downwardly movable under the action of gravity in said channel towards said vertical surface, said locking member in the form of a right circular cylinder arranged with its axis perpendicular to the axis of said channel and formed with a chamfer at the end of said cylinder adjacent the slot in said channel; and a stop member at the lower end of said channel limiting the downward movement of said locking member at a lower limiting position providing clearance between the locking member and at least one of said surfaces of the channel whereby said locking member cannot jam in said channel.
Claim 3
Dependent Claim
18 words
A holder as in claim 1 in which said stop member comprises a pin extending into said channel.
Claim 4
Dependent Claim
32 words
A holder as in claim 1 in which at least a portion of said holder is formed of a magnetized magnetizable material, the magnetic field of which is effective within said channel.
Claim 5
Dependent Claim
22 words
A holder as in claim 1 in which means are provided limiting the upward movement of said locking member in said channel.
Claim 6
Dependent Claim
52 words
A holder as in claim 1 in which said locking member comprises a cylinder having a chamfer at the end thereof adjacent the slot in said channel; said chamfer having an angle with respect to the cylindrical surface at least as great as the blade angle of a knife to be held.
Claim 7
Dependent Claim
26 words
A holder as in claim 1 in which a cushioninG member is arranged in said channel at the rear thereof opposite the slot in said channel.
