Abstract
Abstract An implement rack having upper and lower slotted members mounted on a support. The slots are so shaped and disposed as to receive, from the front of the rack, knife blades at off-vertical angles, the knives then resting on the upper member at the bases of their handles and swinging toward vertical positions. Tongues between the members prevent the blades from being withdrawn forwardly from the rack in their vertical or more nearly vertical positions. Such operation of the rack is predicated upon the utilization of knives having their centers of gravity in the blades. The rack also can be used for culinary utensils. The invention further encompasses a unique method of inserting such knives and implements into the rack, of retaining the knives within the rack in a manner which reduces the likelihood of accidental release, and of permitting convenient removal of the knives from the rack. This invention is intended for use as a fixture to be affixed to a vertical surface.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
336 words
A rack for supporting an implement constituting an elongated work member having a handle at one end and having its weight so distributed that the center of gravity of the implement is below the handle, said rack comprising a. a support, b. an upper member having a front edge, c. a lower member beneath the upper member and having a front edge, d. means providing a slot in the upper member running rearwardly from an opening in the front edge of said upper member, e. means providing a slot in the lower member running rearwardly from an opening in the front edge of said lower member, f. said slots being substantially parallel in a vertical plane with one edge of the slot of (e) laterally spaced from said vertical plane, so that said one edge of the lower slot is vertically disaligned from the corresponding edge of the upper slot, g. said top slot being narrower than the corresponding dimension of said handle when the implement is in said support, h. means permitting moving of the work member rearwardly from the front of the rack and into the slots and toward said support to a retained position, said means permitting moving of the work member rearwardly being vertically disaligned with a vertical plane, i. the opposite edge of the lower slot being less vertically disaligned from the corresponding edge of the upper slot whereby when an implement is introduced into said slots from the front of the rack by the means of (h) and released, the implement will pivot about the junction between the handle and the work member, so that the implement will swing to a retained position toward the opposite edge of the lower slot, and j. means blocking moving of the work member forwardly out of the slots when the implement is in its retained position whereby the implement cannot be moved forwardly from the support without previously aligning the work member with the first named set of edges of the two slots.
Claim 2
Dependent Claim
336 words
A rack for supporting an implement constituting an elongated work member having a handle at one end and having its weight so distributed that the center of gravity of the implement is below the handle, said rack comprising a. a support, b. an upper member having a front edge, c. a lower member beneath the upper member and having a front edge, d. means providing a slot in the upper member running rearwardly from an opening in the front edge of said upper member, e. means providing a slot in the lower member running rearwardly from an opening in the front edge of said lower member, f. said slots being substantially parallel in a vertical plane with one edge of the slot of (e) laterally spaced from said vertical plane, so that said one edge of the lower slot is vertically disaligned from the corresponding edge of the upper slot, g. said top slot being narrower than the corresponding dimension of said handle when the implement is in said support, h. means permitting moving of the work member rearwardly from the front of the rack and into the slots and toward said support to a retained position, said means permitting moving of the work member rearwardly being vertically disaligned with a vertical plane, i. the opposite edge of the lower slot being less vertically disaligned from the corresponding edge of the upper slot whereby when an implement is introduced into said slots from the front of the rack by the means of (h) and released, the implement will pivot about the junction between the handle and the work member, so that the implement will swing to a retained position toward the opposite edge of the lower slot, and j. means blocking moving of the work member forwardly out of the slots when the implement is in its retained position whereby the implement cannot be moved forwardly from the support without previously aligning the work member with the first named set of edges of the two slots.
Claim 3
Dependent Claim
73 words
The implement rack of claim 1 in which a front member connects the upper member and the lower member, said front member having means providing a slot, said slot being inclined from the vertical and extending between the upper slot and the one edge of the lower slot, so that a tongue is defined in said front member by said slot in said front member and the front edge of the lower slot.
Claim 4
Dependent Claim
13 words
The implement rack of claim 1 in which the implement is a knife.
Claim 5
Dependent Claim
36 words
The implement rack of claim 1 in which the base and the frame are composed of a plastic selected from the group consisting of an acrylic resin, cellulose acetate, cellulose acetate butyrate, nylon, polyethylene and polypropylene.
Claim 6
Dependent Claim
17 words
The implement rack of claim 1 in which the upper member and the lower member are transparent.
Claim 7
Dependent Claim
27 words
The implement rack of claim 1 in which the slots in the upper and lower members run rearwardly at an acute angle from perpendicular to the support.
Claim 8
Dependent Claim
22 words
The implement rack of claim 1 in which the slots in the upper and lower members run rearwardly perpendicular to the support.
Claim 9
Dependent Claim
21 words
The implement rack of claim 1 in which the support includes a lower panel to limit front-to-back tilting of the implement.
Claim 10
Dependent Claim
25 words
The implement rack of claim 8 in which a panel depends from the lower panel, said dependent panel being substantially perpendicular to the lower panel.
Claim 11
Dependent Claim
362 words
A rack for supporting an implement constituting an elongated work member having a handle at one end and having its weight so distributed that the center of gravity of the implement is below the handle, said rack comprising a. a support, b. an upper member having a front edge, c. a lower member beneath the upper member and having a front edge, d. means providing a slot in the upper member running rearwardly from an opening in the front edge of said upper member, e. means providing a slot in the lower member running rearwardly from an opening in the front edge of said lower member, f. said slots being substantially parallel in a vertical plane with one edge of the slot of (e) laterally spaced from said vertical plane, so that said one edge of the lower slot is vertically disaligned from the corresponding edge of the upper slot, g. said top slot being narrower than the corresponding dimension of said handle when the implement is in said support, h. the opposite edge of the lower slot being less vertically disaligned from the corresponding edge of the upper slot whereby when an implement is introduced into said slots from the front of the rack and released, the implement will pivot about the junction between the handle and the work member, so that the implement will swing to a retained position toward the opposite edge of the lower slot, and i. a front member, said front member connecting said upper member and said lower member, said front member having means providing a slot, said slot being inclined from the vertical and extending between said upper slot and the one edge of said lower slot, so that a tongue is defined in said front member by said slot in said front member and the front edge of said lower slot, said tongue blocking moving of the work member forwardly out of said upper and lower slots when the implement is in its retained position whereby the implement cannot be moved forwardly from the support without previously aligning the work member with the first named set of edges of the upper and lower slots.
