Abstract

Abstract A card index drawer comprising bottom (2) and wall panels (3, 4, 5, 6) manufactured as individual parts, having panel connections formed by pairwise interengaging marginal portions (9, 11, 12, 15, 17, 18) of adjacent panels, effected by mutual telescoping, wherein stop members (27, 28) or stop members (25, 26) can be provided which determine the assembly end position of the telescoping of marginal portions of adjacent panels in the sense of sliding into one another, and prevent marginal portions of adjacent panels from telescoping in the sense of sliding out of the assembly end position.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 433 words
A drawer comprising: a. an individual bottom panel and first and second pairs of oppositely situated individual wall panels, said second pair of wall panels extending along the length of the drawer, and means for connecting adjacent wall panels together including mutually telescoping portions, in a vertical direction, on adjacent panels, including each telescopic connection comprising a marginal zone on each side of each of said first pair of wall panels bent from the panel through 90° in the direction of the other panel to be connected thereto, and further bent through 180° with a marginal strip being located in a plane substantially parallel to that of said portion bent through 90°, and on each side of each of said second pair of panels a marginal zone bent through 180° outwardly with respect to the panel to be connected thereto, with two bends through 180° being such that the marginal zones are telescoping one into the other with a sliding fit; b. means for connecting the bottom panel and said second pair of oppositely situated wall panels together including mutually telescoping portions in a longitudinal direction on the marginal adjacent portions of the bottom panel and the second pair of oppositely situated wall panels, each telescopic connection comprising a marginal zone bent from each of said second pair of wall panels through 90° in the direction of the bottom panel, and further bent through 180° with a marginal strip being located in a plane substantially parallel to that of said portion bent through 90°, and on the bottom panel a marginal zone bent through 180° from the bottom panel outwardly with respect to wall panel to be connected thereto, which two bends through 180° being such that the marginal zones are telescoping one into the other with a sliding fit; c. stops formed on the panels to determine the assembly end position of telescoping of the marginal portions of adjacent panels in the direction of sliding into one another; d. stop members stopping the telescopic movement of marginal zones of adjacent panels in the sense of sliding out of the assembly end position, said stop members being formed by one or more recessed portions in a marginal zone of a panel mating with one or more projections in a corresponding marginal zone of the adjacent panel; and e. one of said first pair of wall panels forming the front of the drawer and being contiguous to the bottom panel with a lip bent through 90° towards the bottom panel, and said bent lip being contiguous to the bottom panel through a self-adhesive strip.
Claim 2
Dependent Claim 433 words
A drawer comprising: a. an individual bottom panel and first and second pairs of oppositely situated individual wall panels, said second pair of wall panels extending along the length of the drawer, and means for connecting adjacent wall panels together including mutually telescoping portions, in a vertical direction, on adjacent panels, including each telescopic connection comprising a marginal zone on each side of each of said first pair of wall panels bent from the panel through 90° in the direction of the other panel to be connected thereto, and further bent through 180° with a marginal strip being located in a plane substantially parallel to that of said portion bent through 90°, and on each side of each of said second pair of panels a marginal zone bent through 180° outwardly with respect to the panel to be connected thereto, with two bends through 180° being such that the marginal zones are telescoping one into the other with a sliding fit; b. means for connecting the bottom panel and said second pair of oppositely situated wall panels together including mutually telescoping portions in a longitudinal direction on the marginal adjacent portions of the bottom panel and the second pair of oppositely situated wall panels, each telescopic connection comprising a marginal zone bent from each of said second pair of wall panels through 90° in the direction of the bottom panel, and further bent through 180° with a marginal strip being located in a plane substantially parallel to that of said portion bent through 90°, and on the bottom panel a marginal zone bent through 180° from the bottom panel outwardly with respect to wall panel to be connected thereto, which two bends through 180° being such that the marginal zones are telescoping one into the other with a sliding fit; c. stops formed on the panels to determine the assembly end position of telescoping of the marginal portions of adjacent panels in the direction of sliding into one another; d. stop members stopping the telescopic movement of marginal zones of adjacent panels in the sense of sliding out of the assembly end position, said stop members being formed by one or more recessed portions in a marginal zone of a panel mating with one or more projections in a corresponding marginal zone of the adjacent panel; and e. one of said first pair of wall panels forming the front of the drawer and being contiguous to the bottom panel with a lip bent through 90° towards the bottom panel, and said bent lip being contiguous to the bottom panel through a self-adhesive strip.
