Abstract
Abstract A wall system comprises a plurality of supporting frames and a plurality of wall panels associated in pairs with each respective frame. The two panels of each pair are interconnected in the regions of their upright marginal portions so as to extend in mutual parallelism and to define a space in which the upright supports of the associated frame are accommodated with clearance from each of the panels. An insulating member is accommodated between one upright support and one of the panels, and another insulating member is accommodated between the other upright support and the other panel. The upright marginal portions of any two adjacent pairs of panels are interconnected in mutual alignment in such a manner that the insulating member associated with the upright support of one pair of panels is situated at the opposite side of the upright support from the side of the upright support of the other pair of panels at which the other insulating member is located so that mediate contact between the two panels of each pair is avoided without sacrificing the stability of the system. The upright supports of each frame are interconnected by transverse beams on which the pair of panels is supported with clearance. Additional rails and rollers may be provided when the wall system is to be used as a sliding partition.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
224 words
In a wall system, a composite wall element comprising two substantially parallel transversely spaced panels; a frame including two upright supports disposed with clearances between said panels, and connecting bars interconnecting said upright supports, each panel being separated by a gap from the respective one of said connecting bars; means for supporting one of said panels only on one of said upright supports and the other panel only on the other upright support; means for attaching a respective panel to said frame, including a first mounting section attached to said frame in region of one of said connecting bars; a second mounting section attached to said respective panel and supported on said first mounting section, a third mounting section attached to said respective panel, and a fourth mounting section mounted on said frame in the region of the other connecting bar for movement between an extended position in which it is disengaged from said third mounting section and a retracted position in which it engages said third mounting section; and means for mechanically connecting said panels to one another, said connecting means having thermally and acoustically insulating properties, whereby said connecting means, together with said clearances between said one panel and said other upright support and between said other panel and said one upright support, thermally and acoustically insulate said panels from one another.
Claim 2
Dependent Claim
224 words
In a wall system, a composite wall element comprising two substantially parallel transversely spaced panels; a frame including two upright supports disposed with clearances between said panels, and connecting bars interconnecting said upright supports, each panel being separated by a gap from the respective one of said connecting bars; means for supporting one of said panels only on one of said upright supports and the other panel only on the other upright support; means for attaching a respective panel to said frame, including a first mounting section attached to said frame in region of one of said connecting bars; a second mounting section attached to said respective panel and supported on said first mounting section, a third mounting section attached to said respective panel, and a fourth mounting section mounted on said frame in the region of the other connecting bar for movement between an extended position in which it is disengaged from said third mounting section and a retracted position in which it engages said third mounting section; and means for mechanically connecting said panels to one another, said connecting means having thermally and acoustically insulating properties, whereby said connecting means, together with said clearances between said one panel and said other upright support and between said other panel and said one upright support, thermally and acoustically insulate said panels from one another.
Claim 3
Dependent Claim
20 words
A wall system as defined in claim 1, wherein each of said panels comprises at least two mutually interconnected plates.
Claim 4
Dependent Claim
29 words
A wall system as defined in claim 1, wherein said connecting means includes a connecting element of sound-absorbing material connecting said panels and spacing the same from one another.
Claim 5
Dependent Claim
20 words
A wall system as defined in claim 3, wherein said connecting element is formed with at least one internal hollow.
Claim 6
Dependent Claim
44 words
A wall system as defined in claim 3, wherein said connecting means further comprises a plurality of connecting members, each rigidly connected to one of said panels; and wherein said connecting element includes at least two projections, each engaging one of said connecting members.
Claim 7
Dependent Claim
25 words
A wall system as defined in claim 5, wherein each of said connecting members at least partially surrounds an upright marginal portion of said panel.
Claim 8
Dependent Claim
58 words
A wall system as defined in claim 5, wherein each of said connecting members is provided with at least one groove formed with a retaining projection therein; and wherein said projections of said connecting element are of a hook-shaped configuration and include a tip engaging the respective retaining projection when said hook-shaped projection is accommodated in said groove.
Claim 9
Dependent Claim
73 words
A wall system as defined in claim 1, wherein said connecting means further comprises a plurality of connecting members, each rigidly connected to one of said panels and each having an abutment surface; and further comprising at least one L-shaped section attached to each of said panels, said supporting means being accommodated between said abutment surface and said L-shaped section so that relative movement of said panels and said upright supports is prevented.
Claim 10
Dependent Claim
37 words
A wall system as defined in claim 1, and further comprising at least one additional second means accommodated in the other of said clearances between said one of said upright supports and the other of said panels.
Claim 11
Dependent Claim
94 words
A wall system as defined in claim 1, comprising an additional composite wall element similar to said composite wall element and located adjacent thereto in substantially the same general plane, said one upright support of one of said composite wall elements and said other upright support of the other composite wall element being close to one another; and wherein said connecting means also connects said composite wall elements to one another and cooperates with the supporting means associated with said close upright supports to prevent displacement of said panels relative to said upright supports.
Claim 12
Dependent Claim
55 words
A wall system as defined in claim 10, wherein said connecting means further comprises a plurality of elongated connecting members, each connected to one of said panels and provided with a longitudinally extending recess; and an elongated aligning member accepted into said recesses of two adjacent connecting members for aligning said panels with one another.
Claim 13
Dependent Claim
22 words
A wall system as defined in claim 1, and further comprising insulating material at least partially filling the space between said panels.
Claim 14
Dependent Claim

A wall system as defined in claim 12, wherein said insulating material is in form of an insulating layer attached to an inner side of at least one of said panels which faces the other panel and wherein the thickness of said layer is less than the distance between said panels.
Claim 15
Dependent Claim
46 words
A wall system as defined in claim 12, wherein said insulating material is in form of an insulating layer attached to a respective inner side of each of said panels; and wherein the combined thickness of said layers is less than the distance between said panels.
