Abstract

Abstract The novel, knocked-down storage trunk comprising the present invention includes two rigid, molded plastic shells and pairs of side and end walls. In the assembled condition a first pair of lower, inner and outer, concentric clamp rings are used to secure the lower edge of the side and end walls to the lower shell. A second, upper pair of inner and outer concentric clamp rings are secured to the upper edges of the side and end walls. Mating inner and outer vertical corner members are secured to each other and are captured in the upper and lower pairs of concentric clamp rings. The upper shell is hingedly secured to the rear side wall and conventional locks extend between and serve to couple the upper shell and the front side wall. In the knocked-down condition the upper shell nests within the lower shell and the lower shell is seated within the lower concentric pair of clamp rings. The side and end walls may be loosely placed within either of the upper or lower shells so that the carton that is required to ship the storage trunk in the knocked-down condition is substantially smaller in volume than a carton that would be required if the trunk were of the conventional type that could not be knocked down. The clamp rings may be formed, such as by an extrusion process, with channels for receiving welts or ribs that are formed integrally with the longitudinal edge portions of the side and end walls for gripping the side and end walls in the assembled condition. The aforementioned Abstract is neither intended to define the invention of the application which, of course, is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 156 words
A trunk adapted to be erected from a knocked-down condition said trunk comprising: a. a first, lower shell; b. a second, uppershell that is at least partially nestable within said first, lower shell in the knocked-down condition of said trunk; c. a pair of side walls and a pair of end walls that are loose in the knocked-down condition and which are constructed so that they are adapted to be positioned within one of said shells in the knocked-down condition of said trunk; d. first removable clamping means for securing said side and said end walls to said first, lower shell, said first clamping means comprising inner and outer, ringshaped members to each other after said side and said end walls are positioned therebetween; e. second removable clamping means for joining said side and said end walls to each other; and f. hinge means for coupling said second, upper shell to one of said side walls.
Claim 2
Dependent Claim 156 words
A trunk adapted to be erected from a knocked-down condition said trunk comprising: a. a first, lower shell; b. a second, uppershell that is at least partially nestable within said first, lower shell in the knocked-down condition of said trunk; c. a pair of side walls and a pair of end walls that are loose in the knocked-down condition and which are constructed so that they are adapted to be positioned within one of said shells in the knocked-down condition of said trunk; d. first removable clamping means for securing said side and said end walls to said first, lower shell, said first clamping means comprising inner and outer, ringshaped members to each other after said side and said end walls are positioned therebetween; e. second removable clamping means for joining said side and said end walls to each other; and f. hinge means for coupling said second, upper shell to one of said side walls.
Claim 3
Dependent Claim 26 words
The trunk according the claim 1 wherein said side and said end walls include means for connecting said fastener means when said trunk is fully erected.
Claim 4
Dependent Claim 61 words
The trunk according the claim 1 wherein said ringshaped members include elongated channels therein and wherein said fastener means further include elongated projections on said first, lower shell and said side and said end walls whereby said projections engage said channels and prevent movement of said side and said end walls in a direction perpendicular to the axis of said channels.
Claim 5
Dependent Claim 14 words
The trunk according to claim 3 wherein said elongated projection is an offset lip.
Claim 6
Dependent Claim 14 words
The trunk according to claim 3 wherein said elongated projection is an integral rib.
Claim 7
Dependent Claim 28 words
The trunk according to claim 3 wherein said elongated projection is a welt that is rigidly attached to said member that is secured by said first clamping means.
Claim 8
Dependent Claim 39 words
The trunk according to claim 1 wherein said second clamping means comprises inner and outer ring-shaped members and removable fastener means for securing said ring-shaped members to each other after said side and said end walls are positioned therebetween.
Claim 9
Dependent Claim 26 words
The trunk according to claim 7 wherein said side and said end walls included means for connecting said fastener means when said trunk is fully erected.
Claim 10
Dependent Claim 61 words
The trunk according to claim 7 wherein said ring-shaped members include elongated channels therein and wherein said fastener means further include elongated projections on said first, lower shell and said side and said end walls whereby said projections engage said channels and prevent movement of said side and said end walls in a direction perpendicular to the axis of said channels.
Claim 11
Dependent Claim 14 words
The trunk according to claim 9 wherein said elongated projection is an offset lip.
Claim 12
Dependent Claim 14 words
The trunk according to claim 9 wherein said elongated projection is an integral rib.
Claim 13
Dependent Claim 28 words
The trunk according to claim 9 wherein said elongated projection is a welt that is rigidly attached to said member that is secured by said first clamping means.
Claim 14
Dependent Claim 25 words
The trunk according to claim 1 wherein there is further included corner brace means at the juncture of each said side and said end wall.
Claim 15
Dependent Claim 30 words
The trunk according to claim 13 wherein said corner brace means comprises inner and outer channels and fastener means for securing said inner and said outer channels to each other.
Claim 16
Dependent Claim 27 words
The trunk according to claim 13 wherein said corner brace means extend between and are secured at the end thereof by said first and second clamping means.
Claim 17
Dependent Claim 38 words
The trunk according to claim 1 wherein there is further included linkage means extending between said second shell and said side walls, said linkage means being adapted to maintain said trunk in the open condition when fully erected.
Claim 18
Dependent Claim 30 words
The trunk according to claim 1 wherein there is further included a removable tray and means for supporting said tray internally of said trunk when said trunk is fully erected.
Claim 19
Dependent Claim 29 words
The trunk according to claim 1 wherein there is further included lock means for securing said second, upper shell in the closed condition when said trunk is fully erected.
Claim 20
Dependent Claim 36 words
The trunk according to claim 1 wherein at least one of said pair of end walls is at least partially curved at the end thereof to define the corners of said trunk in the erected condition.
