US3592345A — Erectible metal shelving

Claim 1

Independent Claim 261 words

An erectible shelving comprising: a. a pair of spaced upright metal posts, each of said posts having a pair of parallel flanges projecting therefrom with the flanges on each of said posts extending toward the other post, each of said pair of flanges having aligned keyhole-shaped openings therethrough, each of said openings having an upper portion and an elongated portion extending downwardly from the upper portion and being narrower than the width of the upper portion; b. a flat sheet metal brace extending between said posts with each end of the brace fitting betwEen the flanges of a separate one of the posts, said brace having an opening through each end thereof of the same size and shape as the upper portion of the keyhole-shaped openings in the flanges; and c. a separate pin extending through each of the aligned openings in the flanges and the opening in the brace to secure the brace to the posts, each of said pins having a central portion fitting in the opening in the brace and end portions projecting from the central portion and fitting in the lower portions of the keyhole-shaped openings in the flanges, the central portion of each pin having a transverse shape and size corresponding to the shape and size of the openings in the brace and an axial dimension equal to the thickness of the brace, and the end portions have a transverse area smaller than the transverse area of the central portion and one transverse dimension equal to the width of the lower portion of the keyhole-shaped openings.

Claim 2

Dependent Claim 261 words

An erectible shelving comprising: a. a pair of spaced upright metal posts, each of said posts having a pair of parallel flanges projecting therefrom with the flanges on each of said posts extending toward the other post, each of said pair of flanges having aligned keyhole-shaped openings therethrough, each of said openings having an upper portion and an elongated portion extending downwardly from the upper portion and being narrower than the width of the upper portion; b. a flat sheet metal brace extending between said posts with each end of the brace fitting betwEen the flanges of a separate one of the posts, said brace having an opening through each end thereof of the same size and shape as the upper portion of the keyhole-shaped openings in the flanges; and c. a separate pin extending through each of the aligned openings in the flanges and the opening in the brace to secure the brace to the posts, each of said pins having a central portion fitting in the opening in the brace and end portions projecting from the central portion and fitting in the lower portions of the keyhole-shaped openings in the flanges, the central portion of each pin having a transverse shape and size corresponding to the shape and size of the openings in the brace and an axial dimension equal to the thickness of the brace, and the end portions have a transverse area smaller than the transverse area of the central portion and one transverse dimension equal to the width of the lower portion of the keyhole-shaped openings.

Claim 3

Dependent Claim 72 words

An erectible shelving in accordance with claim 1 in which the flanges of each of said posts have a plurality of the keyhole-shaped openings longitudinally spaced along the flanges, the brace has a pair of openings therethrough at each end thereof with each of the openings in the brace being in alignment with a separate set of the keyhole-shaped openings and a separate pin extends through each of the sets of openings.

Claim 4

Dependent Claim 266 words

An erectible shelving comprising: a pair of spaced upright posts, each of said posts having vertical walls and an opening through one of the vertical walls; a rectangular sheet metal brace extending horizontally between said posts; a separate hook integral with each end of said brace, each of said hooks including a first portion extending from its respective end of the metal sheet in the same plane as the metal sheet, a second portion extending from the end of the first portion and perpendicular to the plane of the metal sheet, and a third portion extending downwardly from the end of the second portion, the second portion of each hook extending through an opening in the wall of a post and resting on the bottom edge of the opening, and the third portion extending downwardly along the wall of the post; and a separate camming member slidably supported on the brace at each end thereof and extending along the entire height of the end, each of said camming members having an edge which is juxtaposed to and parallel with an end edge of the metal sheet and an elongated opening therethrough which extends at an angle to said edge of the camming member, and a separate headed pin extending through the opening in each of the camming members and secured to said metal sheet so as to secure the camming members to the metal sheet but allow relative movement between the camming members and the metal sheet, each of said camming members engaging a wall of its respective post to lock the brace to the posts.

Claim 5

Dependent Claim 266 words

An erectible shelving comprising: a pair of spaced upright posts, each of said posts having vertical walls and an opening through one of the vertical walls; a rectangular sheet metal brace extending horizontally between said posts; a separate hook integral with each end of said brace, each of said hooks including a first portion extending from its respective end of the metal sheet in the same plane as the metal sheet, a second portion extending from the end of the first portion and perpendicular to the plane of the metal sheet, and a third portion extending downwardly from the end of the second portion, the second portion of each hook extending through an opening in the wall of a post and resting on the bottom edge of the opening, and the third portion extending downwardly along the wall of the post; and a separate camming member slidably supported on the brace at each end thereof and extending along the entire height of the end, each of said camming members having an edge which is juxtaposed to and parallel with an end edge of the metal sheet and an elongated opening therethrough which extends at an angle to said edge of the camming member, and a separate headed pin extending through the opening in each of the camming members and secured to said metal sheet so as to secure the camming members to the metal sheet but allow relative movement between the camming members and the metal sheet, each of said camming members engaging a wall of its respective post to lock the brace to the posts.

Claim 6

Dependent Claim 67 words

An erectible shelving in accordance with claim 3 in which the brace has parallel flanges extending perpendicularly from the top and bottom edges of the metal sheet, each of said flanges has a separate slot therein extending longitudinally from each end thereof, and each of the camming members extends across the metal sheet and through the slots in the flanges at its respective end of the brace.
