Abstract
Abstract @ A double walled panel (1) comprising on its small longitudinal sides (2a, 2b) a profiling formed in cross-section by a curved nose (7) which faces wide side surface (10), the base of which being situated at a distance from the same wide side surface (10) and a free-standing thickening (6) - as seen in cross-section - being disposed at the other small side (2a) and supported near the same wide side surface (10) fitting into an adjacent panel recess (5) enclosed by its curved nose (7).

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
172 words
A double-walled panel having a first pair of longitudinally extending opposed sides and a second pair of longitudinally extending relatively narrow opposed sides, each of the narrow longitudinal sides comprising a profiling formed from recesses and frames, the profiling on a first of the narrow longitudinal sides being formed so as functionally to complement the profiling on the second of the narrow longitudinal sides whereby two adjacent panels can be inter-engaged, characterised in that the panel has on one narrow side a frame which, in cross-section, forms a curved nose facing towards one of the wider side surfaces, the base of the nose being spaced from said one wider side surface, and the free end of the nose enclosing a recess situated at said one wider side surtace, and the panel further having a free-standing thickening disposed at the other narrow side and supported near said one wider side surface of the panel, the thickening being adapted to fit into the recess enclosed by the curved nose defined in an adjacent panel.
Claim 2
Dependent Claim
172 words
A double-walled panel having a first pair of longitudinally extending opposed sides and a second pair of longitudinally extending relatively narrow opposed sides, each of the narrow longitudinal sides comprising a profiling formed from recesses and frames, the profiling on a first of the narrow longitudinal sides being formed so as functionally to complement the profiling on the second of the narrow longitudinal sides whereby two adjacent panels can be inter-engaged, characterised in that the panel has on one narrow side a frame which, in cross-section, forms a curved nose facing towards one of the wider side surfaces, the base of the nose being spaced from said one wider side surface, and the free end of the nose enclosing a recess situated at said one wider side surtace, and the panel further having a free-standing thickening disposed at the other narrow side and supported near said one wider side surface of the panel, the thickening being adapted to fit into the recess enclosed by the curved nose defined in an adjacent panel.
Claim 3
Dependent Claim
24 words
A double-walled panel according to claim 1 , characterised in that the curved nose is of hollow construction and internally provided with reinforcing partitions.
Claim 4
Dependent Claim
53 words
A double-walled panel according to claim 1 or 2, characterised in that the free-standing thickening is supported on a frame which is parallel to but spaced from said one wider side surface and which has a support frame which extends from said one wider side surface to the parallel frame at the thickening.
Claim 5
Dependent Claim
66 words
A double-walled panel according to any of claims 1 to 3, characterised in that additional frames are provided at the two narrow sides spaces respectively from the curved nose and from the free-standing thickening, the additonal frames, in cross-section, having the shape of a hollow nose, enclosing a recess between the latter and the back of the curved nose, and the frame with the thickening respectively.
Claim 6
Dependent Claim
44 words
A double-walled panel according to claim 4, characterised in that the hollow nose has a widened and curved end fase spaced from but facing the thickening, the curvature of the end face being adapted to the curvature of the back of the curved nose.
Claim 7
Dependent Claim
25 words
A double-walled panel according to claim 4 or 5, characterised in that the hollow nose associated with the-thickening is internally provided with a renforcing partition.
Claim 8
Dependent Claim
65 words
A double-walled panel according to any of claims 4 to 6, characterised in that the hollow nose associated with the thickening has, at the side remote from the thickening, a portion which is set back with respect to the other of the wider sides of the panel, against which set-back part can bear the ollow nose at said one narrow side of an adjacent panel.
Claim 9
Dependent Claim
36 words
A double-walled panel according to claim 3 or any of claims 4 to 7, when dependent on claim 3, characterised in that the thickening has a round cross-section with a flattened portion near the support frame.
Claim 10
Dependent Claim
24 words
A double-walled panel according to claim 8, characterised in that the flattened portion and the support frame extend at right angles to one another.
Claim 11
Dependent Claim
57 words
A double-walled panel according to any of claims 4 to 7 or claims 7 or 8 when dependent on claim 4, characterised in that an insert is arranged to lit into the recess between the hollow nose and the thickening, with which insert can co-operate the hollow nose on said one narrow side of an adjacent panel.
Claim 12
Dependent Claim
17 words
A double-walled panel according to claim 10, characterised in that the insert is made from elastic material.
Claim 13
Dependent Claim
52 words
A double-walled panel according to claim 10, characterised in that the insert is made of metal and is provided, at least on the side remote from the thickening, with a curved side surface co-operating with a curved side surface of the hollow nose on said one nallow side of an adjacent panel.
Claim 14
Dependent Claim
35 words
A double-walled panel according to any of the pie- ceding claims, characterised in that partitions extent between the wider side walls of the panel in the longitudinal direction thereof, the panel being made of plastics.
Claim 15
Dependent Claim
35 words
A double-walled panel according to claim 13, characterised in that additional reinforcing partitions are provided at the narrow sides between the wider side walls and extend at an angle with respect to the longitudinal partitions.
Claim 16
Dependent Claim
83 words
A cover strip for use with a double-walled panel according to any of the preceding claims, characterised in that the strip comprises a cap which is adapted to fit the narrow sides of the panel and can engage around the wider side walls thereof, the cap at one end comprising a pin which is arranged to fit into the free-standing thickening, and at the other side a recess whereby to engage with clearance around the pin on a strip of an adjacent panel.
Claim 17
Dependent Claim
38 words
A cover strip according to claim 15, characterised in that at the locations engaging around the wider side walls of the panel are provided lugs which fit into apertures formed in the wider sides walls of the panel.
