Abstract
Abstract The dividing wall is assembled from a plurality of inherently rigid wall elements (10). A wall element of the wall was a frame composed of vertical frame sides (11, 12) and horizontal frame sides (13, 14), an inner plate (22) suitable for anchoring nails or screws and cover plates (20, 21) which can have a thin construction, a stiffening honeycomb filling (23) being provided between the cover plates (20, 21). The vertical frame sides (11, 12) are provided with a conical external groove (15) or an external spring pin (16) which fits into the latter, so that adjoining wall elements can be put together so as to be self-centering, wherein the reciprocal connection is effected by inserting coupling pegs of one wall element in catch openings of the other wall element. The dividing wall thus is made of lightweight individual wall elements which can be assembled quickly.

Total Claims: 10
Claim 1
Independent Claim
249 words
Dividing wall, especially for an exposition hall, comprising a plurality of rectangular, inherently rigid, detachably connectable wall elements (10, 10'), each of said wall elements comprising: a plurality of coupling members (31-33) for connecting said wall elements, a frame including a plurality of vertical frame sides (11, 12) and horizontal frame sides (13, 14) connected to each other by separate corner pieces (28), said fame sides being section rails and said vertical frame sides having outer front sides, at least the outer front sides of the vertical frame sides of the frame being provided with one of an external groove (15) and an external spring pin (16), said external spring pin (16) fitting another of said external grooves of another of said wall elements, said spring pin having a conical cross section, a cover plate (20, 21) attached to each side of said frame, said vertical frame sides having outer lateral contact faces (18) for an edge region of both of said cover plates (20, 21), an inner plate (22) located in said frame between said cover plate (20, 21) so as to form an intermediate space between each of said cover plates and said inner plate, said vertical frame sides having at least one interior shoulder surface (19, 19a) on which said inner plate (22) rests, said inner plate being made of a material suitable for anchoring holding elements, and a stiffening, honeycomb filling (23) located in said intermediate spaces between said cover plates and said inner plate.
Claim 2
Dependent Claim
249 words
Dividing wall, especially for an exposition hall, comprising a plurality of rectangular, inherently rigid, detachably connectable wall elements (10, 10'), each of said wall elements comprising: a plurality of coupling members (31-33) for connecting said wall elements, a frame including a plurality of vertical frame sides (11, 12) and horizontal frame sides (13, 14) connected to each other by separate corner pieces (28), said fame sides being section rails and said vertical frame sides having outer front sides, at least the outer front sides of the vertical frame sides of the frame being provided with one of an external groove (15) and an external spring pin (16), said external spring pin (16) fitting another of said external grooves of another of said wall elements, said spring pin having a conical cross section, a cover plate (20, 21) attached to each side of said frame, said vertical frame sides having outer lateral contact faces (18) for an edge region of both of said cover plates (20, 21), an inner plate (22) located in said frame between said cover plate (20, 21) so as to form an intermediate space between each of said cover plates and said inner plate, said vertical frame sides having at least one interior shoulder surface (19, 19a) on which said inner plate (22) rests, said inner plate being made of a material suitable for anchoring holding elements, and a stiffening, honeycomb filling (23) located in said intermediate spaces between said cover plates and said inner plate.
Claim 3
Dependent Claim
31 words
Dividing wall according to claim 1, the outer front sides of the two vertical frame sides (11, 12) having edge stops (30) for the frame sides of adjacent wall elements (10').
Claim 4
Dependent Claim
20 words
Dividing wall according to claim 1, wherein the external spring pin (16') of the vertical frame said (12') is hollow.
Claim 5
Dependent Claim
47 words
Dividing wall according to claim 1, wherein at least the vertical frame sides (11', 12') are provided interiorly with a plurality of longitudinal grooves (17') having a substantially circular cross section and a groove opening (17a) which is reduced in diameter for the purpose of anchoring screws.
Claim 6
Dependent Claim
118 words
Dividing wall according to claim 1, wherein each of the horizontal frame sides (13, 14) of the frame have a gutter-shaped cross section with a gutter opening (26) which is situated on the outer front side of the horizontal frame side and said gutter opening has opposing horizontal lips (27), and wherein the wall elements (10, 10') are provided with at least one side wall shoulder strip (34), said side wall shoulder strip resting against one of the cover plates (20, 21) and having detachable end plates (35), each of said detachable end plates having a part which projects laterally over the shoulder strip (34) and engages in the gutter opening (26) with an angled edge portion (40).
Claim 7
Dependent Claim
