Abstract
Abstract The enclosure assembly, being particularly but not exclusively conceived for use over electric cable splices, comprises a sleeve of an elastomer material, a support whereover the sleeve is fitted in a condition of elastic expansion, said sleeve being adapted to shrink around the elongate cylindrical objects upon removal of the support. The support comprises two substantially cylindrical, tubular bodies having ends abutted coaxially with each other in mutual continuation relationship; the abutted ends are disposed at substantially inward locations of the sleeve longitudinal extension. Thus, the support removal can begin from a predetermined internal region of the sleeve; the sleeve starts shrinking over the splice within said internal region, and any axial deformations in the sleeve would leave the sleeve positioning relatively to said predetermined internal region unaffected.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
260 words
An assembly of an elastic sleeve with a supporting body in the bore of said sleeve for the application of said sleeve to a cylindrical body, said assembly comprising: a radially stretched sleeve of elastic material, the bore of said sleeve having an inner wall of a predetermined radius in its unstretched state and said sleeve having opposite ends; a support comprising two tubular bodies disposed within the bore of said sleeve, each of said bodies having a longitudinal axis, having an external surface around said axis of a radius greater than said predetermined radius and engaging said inner wall of said sleeve to cause radial stretching of said sleeve and having an internal surface around said axis of a radius smaller than the radius of said external surface, said bodies having opposite ends and being mounted co-axially with one end of a first one of said bodies abutting the end of the other second one of said bodies intermediate said ends of said sleeve and in mutual continuation; and a pair of pulling means, one of said pulling means being connected to said one end of first one of said bodies and extending within the internal surface of said first one of said bodies toward the opposite end of said first one of said bodies and the other of said pulling means being connected to said one end of said second one of said bodies and extending within the internal surface of said second one of said bodies toward the opposite end of said second one of said bodies.
Claim 2
Dependent Claim
260 words
An assembly of an elastic sleeve with a supporting body in the bore of said sleeve for the application of said sleeve to a cylindrical body, said assembly comprising: a radially stretched sleeve of elastic material, the bore of said sleeve having an inner wall of a predetermined radius in its unstretched state and said sleeve having opposite ends; a support comprising two tubular bodies disposed within the bore of said sleeve, each of said bodies having a longitudinal axis, having an external surface around said axis of a radius greater than said predetermined radius and engaging said inner wall of said sleeve to cause radial stretching of said sleeve and having an internal surface around said axis of a radius smaller than the radius of said external surface, said bodies having opposite ends and being mounted co-axially with one end of a first one of said bodies abutting the end of the other second one of said bodies intermediate said ends of said sleeve and in mutual continuation; and a pair of pulling means, one of said pulling means being connected to said one end of first one of said bodies and extending within the internal surface of said first one of said bodies toward the opposite end of said first one of said bodies and the other of said pulling means being connected to said one end of said second one of said bodies and extending within the internal surface of said second one of said bodies toward the opposite end of said second one of said bodies.
Claim 3
Dependent Claim
39 words
An assembly as set forth in claim 1 wherein said one end of said first one of said bodies abuts said one end of said second one of said bodies substantially mid-way between said opposite ends of said sleeve.
Claim 4
Dependent Claim
117 words
An assembly as set forth in claim 1 wherein each of said bodies is formed by a plurality of helically wound, contiguous turns of a strip, severable means securing each turn to an adjacent turn and said turns of said body being made of a material of dimensions which provides a radial resistance to the pressure applied thereto by the stretched sleeve sufficient to maintain said sleeve in its stretched state and each of said pulling means is a pull strip extending from a turn at one end of said body within said internal surface for pulling said turns apart and pulling the turns of one said body away from the turns of the other said body.
Claim 5
Dependent Claim
40 words
An assembly as set forth in claim 3 wherein each of said pulling means comprises a strip terminating means secured to an end turn of the supporting body at the end of the supporting body which abuts the other body.
Claim 6
Dependent Claim
46 words
An assembly as set forth in claim 4 wherein said strip terminating means comprises a flexible band extending from said end turn within said internal surface and at least to the end of said supporting body opposite from the end thereof which abuts the other body.
Claim 7
Dependent Claim
21 words
An assembly as set forth in claim 3 wherein the strips of each body are wound in the same helical direction.
Claim 8
Dependent Claim
28 words
An assembly as set forth in claim 3 wherein the abutting ends of the bodies contact each other over at least major portions of the abutting end surfaces.
Claim 9
Dependent Claim
18 words
An assembly as set forth in claim 2 wherein said sleeve has an innermost layer of semi-conductive material.
