Abstract
Abstract A device for enclosing elongate objects comprises a dimensionally-recoverable cover (1) which can be wrapped- around the object and closed by means of closure elements (8, 9) located on the cover. The closure elements (8, 9) are preferably in the form of a row of protuberances spaced apart along the edge portions (2, 3) of the cover, the protuberances of one edge portion being nestable within the protuberances of the other edge portion. The protuberances are preferably provided with retaining elements which lock the nested protuberances together and will accommodate relative movement between adjacent pairs of nested protuberances to allow the device to be recovered onto objects of varying dimensions.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
118 words
A device for enclosing at least part of an elongate object, which comprises a dimensionally-recoverable cover (1), preferably a dimensionally heat-recoverable cover, adapted to be positioned about the object and recovered thereon, the cover having corresponding closure portions (2, 3) which are non-perforate and which can be retained together in a lap configuration by means of a mechanical closure arrangement which comprises a plurality' of closure elements (8, 9) spaced apart along each closure portion, the closure elements. of each closure portion being interlockable with the- closure elements of the corresponding. closure portion so that the closure portions can be retained together and adjacent pairs of engaged closure elements (8, 9) can move with respect to each other..
Claim 2
Independent Claim
118 words
A device for enclosing at least part of an elongate object, which comprises a dimensionally-recoverable cover (1), preferably a dimensionally heat-recoverable cover, adapted to be positioned about the object and recovered thereon, the cover having corresponding closure portions (2, 3) which are non-perforate and which can be retained together in a lap configuration by means of a mechanical closure arrangement which comprises a plurality' of closure elements (8, 9) spaced apart along each closure portion, the closure elements. of each closure portion being interlockable with the- closure elements of the corresponding. closure portion so that the closure portions can be retained together and adjacent pairs of engaged closure elements (8, 9) can move with respect to each other..
Claim 3
Dependent Claim
20 words
A device as claimed in claim 1, wherein the closure portions. extend along or adjacent to edges of the cover.
Claim 4
Dependent Claim
37 words
A device as claimed in claim 1 or claim 2, wherein the adjacent pairs of engaged closure elements can move with respect to each.other during recovery of the cover by change in their separation or relative orientation.
Claim 5
Independent Claim
43 words
A device as claimed in any one of claims 1 to 3, wherein the closure arrangement includes means for retaining the closure elements in engagement during recovery of the cover, which means will accommodate relative movement between adjacent pairs of engaged closure elements.
Claim 6
Dependent Claim
37 words
A device as claimed in claim 4, wherein the closure elements are in the form of protuberances arranged so that a protuberance on one closure portion can be nested within a protuberance on the other closure portion.
Claim 7
Dependent Claim
42 words
A device as claimed in claim 5, wherein the retaining means comprises a plurality of retaining elements each of which can be located about a pair of engaged closure elements and has a recess for receiving the pair of engaged closure elments.
Claim 8
Dependent Claim
45 words
A device as claimed in claim 6, wherein each retaining element for each pair of closure elements is in the form of a cap which can be positioned about the engaged closure elements and then twisted or crimped to grip the pair of closure elements..
Claim 9
Dependent Claim
58 words
A device as claimed in claim 6, wherein the retaining element for each pair of closure elements is in the form of a cap located on each protuberance of the said other closure portion, which caps will allow the protuberances to be nested and can then be twisted or crimped to grip the nested pair of protuberances. -
Claim 10
Independent Claim
45 words
A device as claimed in any one of claims 6 to 8, wherein the protuberance that is nested within the other protuberance of each pair of engaged protuberances has an internal hold-out member to retain the shape of the protuberance during recovery of the cover.
Claim 11
Dependent Claim
63 words
A device as claimed in claim 9 wherein the internal hold-out member and the recess in the retaining means have corresponding non-circular profiles when viewed from above so that the retaining means can accommodate over the pair of engaged protuberances and can be twisted to a position in which the retaining element and internal hold-out member cooperate to lock the protuberances in engagement.
Claim 12
Dependent Claim
93 words
A dimensionally-recoverable device for enclosing at least part of an elongate object, the device having closure portions that can be retained together by means of a closure arrangement which comprises a closure element located on each closure portion, the closure element on each closure portion being engageable with the closure element on the other closure portion, and a retaining element for retaining the closure elements in engagement, the closure elements and retaining element being arranged so that the retaining element can be twisted about the closure elements to lock the closure elements together.
Claim 13
Dependent Claim
93 words
A dimensionally-recoverable device for enclosing at least part of an elongate object, the device having closure portions that can be retained together by means of a closure arrangement which comprises a closure element located on each closure portion, the closure element on each closure portion being engageable with the closure element on the other closure portion, and a retaining element for retaining the closure elements in engagement, the closure elements and retaining element being arranged so that the retaining element can be twisted about the closure elements to lock the closure elements together.
Claim 14
Dependent Claim
38 words
. A device as claimed in claim 11, wherein the closure elements are in the form of protuberances arranged so that the protuberance on one closure portion can be nested within . the protuberance-on the other closure portion..
Claim 15
Dependent Claim
64 words
- A process for producing a device as claimed in claim 1, which comprises forming a cover from a polymeric material, the cover having non perforate closure portions, expanding the cover to render it dimensionally-recoverable, and forming a plurality of closure elements in each closure portion, the closure elements in each closure portions being engageable with. the closure elements in the other closure portion.
Claim 16
Dependent Claim
73 words
A process for enclosing at least part of an elongate object by means of a device as claimed in any one of claims 1 to 10, which comprises positioning the cover about the elongate object so that one closure portion overlies the other closure portion, engaging the closure elements of each closure portions with the closure enelments of the other closure portion, and heating the device to recover the cover about the object.
