Abstract
Abstract Lamp apparatus consisting of assembled polyhedric modules, each module comprising a shaped, hollow polyhedron and a light mounted in the polyhedron. Each polyhedron has sides with circular ribs extending therefrom. The assembly of two consecutive modules is achieved by nesting the circular complementary ribs provided on the sides to be assembled of those two modules. The complementary parts are coaxial and thereby permit each module to rotate independently about the axis.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
72 words
Lamp means consisting of assembled polyhedric modules, each module comprising a shaped, hollow polyhedron and light means mounted in said polyhedron, each polyhedron having sides with circular ribs extending therefrom whereby the assembly of two consecutive modules is achieved by nesting said circular complementary ribs provided on the sides to be assembled of these two modules, the complementary ribs being coaxial and thereby permitting each module to rotate independently about said axis.
Claim 2
Dependent Claim
72 words
Lamp means consisting of assembled polyhedric modules, each module comprising a shaped, hollow polyhedron and light means mounted in said polyhedron, each polyhedron having sides with circular ribs extending therefrom whereby the assembly of two consecutive modules is achieved by nesting said circular complementary ribs provided on the sides to be assembled of these two modules, the complementary ribs being coaxial and thereby permitting each module to rotate independently about said axis.
Claim 3
Dependent Claim
38 words
Lamp means per claim 1, wherein each module is parallelipipedic and that each lateral side comprises sets of concentric circular ribs so arranged that, as regards two opposite sides, the centers of the circles so defined are coaxial.
Claim 4
Dependent Claim
45 words
Lamp means per claim 2, wherein the circular ribs of the two opposite sides of a module have different diameters, with the corresponding ribs differing in diameters approximately by the thickness of one rib, one of the opposite sides being termed complementary to the other.
Claim 5
Dependent Claim
51 words
Lamp means per any one of claims 1-3, wherein a supplementary circular rib is provided at the center of nesting circular ribs, the height of said supplementary rib being half the height of the nexting ribs and being of the same diameter on all sides and concentrical with the other ribs.
Claim 6
Dependent Claim
32 words
Lamp means per claim 4, further comprising a bail having arms which are each provided with a pivot embedded into the central rib of an end side of a strip of modules.
Claim 7
Dependent Claim
44 words
Lamp means per claim 4, wherein one or several modules of a strip being provided at the upper and lower lateral sides with supplementary modules, the modules of a horizontal strip being vertically orientable while the modules nesting along vertical strips are horizontally orientable.
