Abstract
Abstract A knock-down-type storage rack, which includes apertured, upright posts and horizontal cross-beam members in which aligned cross members on opposite sides of the post may be connected to the post through portions of a single aperture. End plates of special shape, attached to the beam portion of the cross member, provide proper abutting cooperation with the post and carry a non-load-bearing safety-lock pin which secures the cross member to one side of the upright post. The safety-pin is spaced from the beam portion so that the pin may be viewed from multiple aisle positions.

Claim 1
Independent Claim
356 words
In a knock-down storage rack which includes apertured, upright posts of generally rectangular cross-section and beam members having ends constructed and adapted for selective connection and disconnection to the posts to provide the storage rack construction, the improvement comprising, in combination, the post providing a front face and a side face transverse to each other, and each provided with a series of spaced apertures, the apertures in the front face each being vertically elongated and having a lower support edge, each end construction of the beam being in the form of a unitary plate shaped to provide a side-engaging portion adapted for attachment to the cross-beam on one surface thereof and substantial surface abutment against a side face of the post by the other surface thereof, and a hooking flange spaced from but substantially parallel to the sideengaging portion, the side-engaging portion being of greater dimension than the end of a beam and providing an exposed section located outwardly of the beam, safety pin means carried on the exposed section of the side-engaging portion and having a locking head adapted for entry into one of the series of apertures in the post''s side when the beam is properly positioned on the post, the hooking flange having an elongated edge for bracing abutment with the face of the post and a plurality of hooks extending outwardly of said bracing edge adapted for entry into a plurality of apertures in the post''s front face for simultaneous supporting engagement with the support edges of the apertures, the connector hooks and said pin being positioned on said plate such that when said hooks are seated in the hook-receiving apertures and said pin is positioned in said pin-receiving aperture, said pin is in spaced non-load-bearing relation with the edges of said pinreceiving aperture, said pin-receiving aperture being elongated and having a widened portion through which said locking head of the pin is extendable and said aperture having narrower upper and lower portions behind which the head of said pin is positionable, and the side-engaging portion of said plate being recessed so as to receive the locking head of said pin therein.

Claim 3
Dependent Claim
50 words
A rack as in claim 1 wherein each of said apertures in said front face includes an upstanding rib positioned substantially centrally along said support edge for dividing said aperture into two hook-receiving portions so that said aperture can simultaneously receive hooks from cross-members on opposite sides of said post.
Claim 4
Dependent Claim
341 words
In a knock-down storage rack which includes apertured, front and back upright posts of generally rectangular cross-section and beam members having ends constructed and adapted for selective connection and disconnection to the posts to provide the storage rack construction, the improvement comprising, in combination, each post providing a front face and a side face transverse to each other, and each provided with a series of spaced apertures, the apertures in the front face each being vertically elongated and having a lower support edge, the end construction of each beam secured to front and back posts being in the form of a unitary plate shaped to provide a side-engaging portion adapted for attachment to the cross-beam on one surface thereof and substantial surface abutment against a side face of the post by the other surface thereof, a hooking flange with a plurality of hooks thereon for entry into a plurality of apertures in the post''s front face spaced from but substantially parallel to the side-engaging portion, the side-engaging portion being of greater dimension than the end of a beam and providing an exposed section located below the beam, and safety pin means carried on the exposed section of the side-engaging portion below said beam and adapted for entry into one of the series of apertures in the post''s side when the beam is properly positioned on the post, the arrangement of safety pin means below the beam permitting visual inspection of all safety pin means for both front and back post-supported beams from a single aisle position, the safety pin means including a locking head for entry into the series of apertures in the post''s side, said series of apertures being elongated and having a widened portion through which the locking head of the pin is extendable, said apertures each having narrower upper and lower portions behind which the head of the pin is positionable, and the side-engaging portion of the plate being recessed so as to receive the locking head of the pin therein when the safety pin means are withdrawn.
