Abstract
Abstract This invention provides an enclosure which can be releasably affixed to others of its kind through handle means on one enclosure and a handle-receiving base structure on the other enclosure. The handle means projects upwardly from the top of one enclosure and includes a bar element which. overhangs the structure which supports the bar element. The base structure of the other enclosure defines a track into which the bar element can slide.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
An enclosure adapted to be releasably affixed to others of its kind, the enclosure comprising: a top, a bottom, handle means projecting upwardly from the top and including a bar element of substantially uniform cross-section along a given axis, and support structure for the bar element, the support structure having a maximum dimension less than that of the bar element in the direction normal both to the axis and to the general plane of the support structure, and base structure projecting downwardly from the bottom and including a track into which a bar element similar to the said bar element may slide in the direction of said axis, but from which such bar element may not be withdrawn in any direction normal to said axis.
Claim 2
Dependent Claim
125 words
An enclosure adapted to be releasably affixed to others of its kind, the enclosure comprising: a top, a bottom, handle means projecting upwardly from the top and including a bar element of substantially uniform cross-section along a given axis, and support structure for the bar element, the support structure having a maximum dimension less than that of the bar element in the direction normal both to the axis and to the general plane of the support structure, and base structure projecting downwardly from the bottom and including a track into which a bar element similar to the said bar element may slide in the direction of said axis, but from which such bar element may not be withdrawn in any direction normal to said axis.
Claim 3
Dependent Claim
67 words
An enclosure adapted to be releasably Affixed to others of its kind, the enclosure comprising: a top, a bottom, a handle projecting upwardly from the top and including support structure and a bar element overhanging said support structure laterally, and base structure projecting downwardly from the bottom and defining a recess adapted to receive in one direction only a bar element similar to the said bar element.
Claim 4
Dependent Claim
67 words
An enclosure adapted to be releasably Affixed to others of its kind, the enclosure comprising: a top, a bottom, a handle projecting upwardly from the top and including support structure and a bar element overhanging said support structure laterally, and base structure projecting downwardly from the bottom and defining a recess adapted to receive in one direction only a bar element similar to the said bar element.
Claim 5
Dependent Claim
26 words
The invention claimed in claim 2, in which the bar element is substantially flat, elongated and of substantially uniform cross-section normal to the direction of elongation.
Claim 6
Dependent Claim
17 words
The invention claimed in claim 3, in which the bar element is slightly tapered at either end.
Claim 7
Dependent Claim
50 words
The invention claimed in claim 3, in which the recess is of substantially uniform C-shaped cross-section, the base structure including first means elongated in one direction and defining said recess, as well as second means extending perpendicularly to said one direction, thereby to define a stable support for said enclosure.
Claim 8
Dependent Claim
32 words
The invention claimed in claim 2, in which the enclosure is substantially cylindrical, and in which both the bar element and the recess are diametrally disposed with respect to the cylindrical enclosure.
Claim 9
Dependent Claim
29 words
The invention claimed in claim 6, in which the enclosure is substantially bi-laterally symmetrical along a diametral plane, both the bar element and recess being cut by said plane.
Claim 10
Dependent Claim
24 words
The invention claimed in claim 7, in which the enclosure is constituted by two separable, semi-cylindrical, substantially identical halves meeting along said diametral plane.
Claim 11
Dependent Claim
42 words
The invention claimed in claim 8, in which the top and bottom are substantially normal to the cylindrical axis, and in which the bar element is substantially flat, elongated, and of substantially uniform cross-section except for a slight taper at either end.
Claim 12
Dependent Claim
64 words
The invention claimed in claim 9, in which the recess is of substantially uniform C-shaped cross-section, the base structure including a first element elongated in the direction of said diametral plane and defining said recess, as well as a second element extending perpendicularly from either side of said first element along another diametral plane, thereby to define a cross-shaped stable support for said enclosure.
