Abstract
Abstract A partition system formed of a plurality of partition panel units held in erect position by an upper securing member and a lower securing member. The lower securing member is fixed to the floor and has a mounting surface in face-to-face relationship with the panel units. The system permits easy erecting of panel units from one side of the wall by slipping the top of each unit into the upper securing member, pivoting the unit into each face-to-face relationship with the mounting surface, adjusting the unit vertically and anchoring the unit in position. An open passage is formed beneath the panel units in the partition structure. This passage easily accommodates various services, such as wiring, and after such services are inserted, it is closed by means of a supporting plate which supports the side of the panel units remote from the mounting surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
A partition structure comprising an upper panel securing member and a substantially L-shaped lower panel securing member, one arm of said L-shaped lower panel securing member forming a securing section adapted to be fixed to the floor and the other arm of said L-shaped lower securing member forming a mounting section having a mounting surface spaced above the securing section, a partition panel unit, said lower securing member permitting unobstructed movement of said partition panel unit from the side of said lower securing member remote from said mounting surface into position in face to face relationship with said mounting surface, said partition panel unit being positioned at its upper end by said upper securing member, screws penetrating said panel unit adjacent its bottom edge and securing said panel unit in face to face relationship with said mounting surface and holding the bottom edge of said partition panel unit spaced from said securing section to provide a longitudinally extending open passage between the bottom of said partition panel unit and said securing section.
Claim 2
Dependent Claim
172 words
A partition structure comprising an upper panel securing member and a substantially L-shaped lower panel securing member, one arm of said L-shaped lower panel securing member forming a securing section adapted to be fixed to the floor and the other arm of said L-shaped lower securing member forming a mounting section having a mounting surface spaced above the securing section, a partition panel unit, said lower securing member permitting unobstructed movement of said partition panel unit from the side of said lower securing member remote from said mounting surface into position in face to face relationship with said mounting surface, said partition panel unit being positioned at its upper end by said upper securing member, screws penetrating said panel unit adjacent its bottom edge and securing said panel unit in face to face relationship with said mounting surface and holding the bottom edge of said partition panel unit spaced from said securing section to provide a longitudinally extending open passage between the bottom of said partition panel unit and said securing section.
Claim 3
Dependent Claim
32 words
A partition structure as defined in claim 1 further comprising a shoe at the bottom of said panel units and wherein said screws extend through at least a portion of said shoe.
Claim 4
Dependent Claim
59 words
A partition structure as defined in claim 1 further comprising a substantially channel shaped shoe on the bottom of said panel unit, said shoe having a pair of spaced flanges embracing opposite faces of the panel adjacent the bottom of said panel and wherein said screws extend through said mounting section and one of said flanges on said shoe.
Claim 5
Dependent Claim
34 words
A partition structure as defined in claim 3 further comprising structural plate means extending from adjacent said securing section to the bottom of said unit, said plate means obstructing the opening into said passage.
Claim 6
Dependent Claim
34 words
A partition structure as defined in claim 2 further comprising structural plate means extending from adjacent said securing section to the bottom of said unit, said plate means obstructing the opening into said passage.
Claim 7
Dependent Claim
30 words
A partition structure as defined in claim 4 wherein said plate means is secured to said panel unit by screws extending through the other of said flanges on said shoe.
Claim 8
Dependent Claim
28 words
A partition structure as defined in claim 5 wherein said plate means is secured to said panel unit by screws extending through a further portion of said shoe.
Claim 9
Dependent Claim
25 words
A partition structure as defined in claim 1 wherein said upper securing member is U-shaped and snugly receives the top end of said panel unit.
Claim 10
Dependent Claim
25 words
A partition structure as defined in claim 3 wherein said upper securing member is U-shaped and snugly receives the top end of said panel unit.
Claim 11
Dependent Claim
25 words
A partition structure as defined in claim 4 wherein said upper securing member is U-shaped and snugly receives the top end of said panel unit.
