Abstract
Abstract A supporting column to which supporting members are attachable which in turn support shelves, brackets, partitions and the like. The column comprises at least one longitudinal member composed of a sleeve provided therein with a lengthwise extending core having radial ribs, the outer edges of which engage tightly the inner wall of the sleeve. The sleeve is provided with at least one circumferential groove of a radial depth which is equal to the wall thickness of the sleeve so that the ribs on the core are exposed and support members may be inserted into the spaces formed between the radial ribs. The longitudinal member preferably is made of at least two axially aligned and telescopically connected sleeves, each having a core with radial ribs therein. One sleeve has its core projecting from one of its ends to extend into the adjacent end of other sleeve which at this end has a portion of its core removed an axial distance which is shorter than the portion of the core extending from the first mentioned sleeve, thereby forming a groove between the two telescopically connected sleeves which permits the attachment of supporting members to the exposed core portion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
106 words
Supporting column to which supporting members may be attached, comprising at least one longitudinal member composed of a sleeve having disposed therein a lengthwise extending core having four lengthwise extending radial ribs arranged at right angles to each other, the outer longitudinal edges of which are fixedly secured the inner wall of said sleeve, said sleeve being interrupted at least at one place along said supporting column over its entire circumference to expose said core for inserting into the spaces formed between each two ribs of said core a supporting member which, when inserted in said spaces, engages said ribs and extends outwardly from said column.
Claim 2
Dependent Claim
106 words
Supporting column to which supporting members may be attached, comprising at least one longitudinal member composed of a sleeve having disposed therein a lengthwise extending core having four lengthwise extending radial ribs arranged at right angles to each other, the outer longitudinal edges of which are fixedly secured the inner wall of said sleeve, said sleeve being interrupted at least at one place along said supporting column over its entire circumference to expose said core for inserting into the spaces formed between each two ribs of said core a supporting member which, when inserted in said spaces, engages said ribs and extends outwardly from said column.
Claim 3
Dependent Claim
101 words
Supporting column according to claim 1, in which said longitudinal member comprises at least two axially connected sleeves each of which has a core fixedly secured therein, and one of said sleeves having one of its ends telescopically and removably inserted therein a portion of the core projecting from one end of the other sleeve, said first mentioned sleeve projecting with its other end axially beyond the end its core therein, the axial length of the projecting part of the core on the other sleeve is greater than the length of the portion of the sleeve which telescopically engages said core.
Claim 4
Dependent Claim
54 words
Supporting column according to claim 1, in which said sleeve at least at one place is provided with a slot extending around the entire periphery of said sleeve, and including a plate-shaped supporting member inserted into said slot and into a space formed between two of said ribs and in communication with said slot.
Claim 5
Dependent Claim
68 words
Supporting column according to claim 1, in which said core projects with one end axially beyond the end of the sleeve and a cap on said projecting end of said core, the height of said cap being smaller than the length of the projecting part of said core, so that a space is formed between the lower edge of said cap and the adjacent end of said sleeve.
Claim 6
Dependent Claim
76 words
Supporting column according to claim 1, in which said core projects with one end axially beyond the end of the sleeve, a cap on said projecting end of said core, the height of said cap being smaller than the length of the projecting part of said core, so that a space is formed between the lower edge of said cap and the adjacent end of said sleeve, and means for locking said cap on said core.
Claim 7
Dependent Claim
14 words

Claim 8
Dependent Claim
14 words
Supporting column, according to claim 1, in which said sleeve has a square cross-section.
Claim 9
Dependent Claim
37 words
Supporting column, according to claim 1, in which said longitudinal member is made by a material molded by extrusion, said material being selected from the group consisting of a light-weight metal, a nonferrous metal and a plastic.
Claim 10
Dependent Claim
16 words
Supporting column, according to claim 1, in which said sleeve and core constitute an integral part.
Claim 11
Dependent Claim
16 words
Supporting column, according to claim 1, in which said core is press fitted into saId sleeve.
