Abstract
Abstract A knock-down construction of an understructure for supporting the top of a table, desk or the like made up of a pair of side panels and a back panel adapted to be interconnected and held together by corner posts or legs which are secured to and support the table top. The side and back panels are formed of sheet metal stampings and have their ends flanged to provide, when in their assembled relation, corner joints having vertically extending angular seats or recesses in which the supporting posts are respectively non-rotatably received. The posts are each provided with self-contained horizontally projecting threaded studs which extend through openings provided in the flanged extremities of the panels for rigidly connecting the panels to one another simultaneously as the assembled panels are connected to the posts. The rear corner posts are provided with two vertically spaced pairs of angularly related threaded studs which respectively project through openings provided therefore in the angularly related flanged extremities of adjoining interconnected panels, while the front corner posts are provided with only two of such studs for securement of said posts to the front ends of the side panels. An open topped accessory tray extends transversely between the front ends of the side panels for pivotal movement about a horizontal axis, with stops provided to limit the tilting of the tray between closed and open positions. The assembled understructure for the table is further rigidified against relative angular displacement of the interconnected back and side panels upon securement of the table top to the top ends of the corner posts.

Total Claims: 11
Claim 1
Independent Claim
297 words
A knock-down construction of a supporting understructure for the top of a table or the like comprising in combination, a. a pair of vertically extending side panels disposed in laterally spaced, parallel relation, each side panel having at its rear end a vertically extending inturned flange and at its front end a vertically extending flange bent upon itself to provide a frontally projecting box-like section inwardly offset from the panel to provide a right angular space or seat extending along the full vertical length of the panel for accommodating therein a vertically extending front leg for the table, b. a vertically disposed back panel extending transversely between the rear ends of said side panels, said back panel being provided at each of its opposite ends with a vertically extending right-angular flange having a terminal branch of which extends freely beyond the end of and is disposed in inwardly spaced parallel relation to said back panel to provide at each said end of said panel a right angular vertically extending space or seat in oppositely facing relation to the space or seat provided at the front end of the adjoining side panel for accommodating therein a vertically extending rear leg for the table, c. a plurality of vertically extending post members or legs of square cross section respectively nested in the vertically extending right-angular spaces or seats provided in the opposite ends of said back panel and the front ends of said side panels, and d. means for rigidly securing said side panels and said back panel to said posts or legs with said rear end flanges of said side panels respectively overlapping said freely extending terminal branches of the end flanges of said back panel and with said posts held secured against rotation about their vertical axes.

A knock-down construction of a supporting understructure for the top of a table or the like comprising in combination, a. a pair of vertically extending side panels disposed in laterally spaced, parallel relation, each side panel having at its rear end a vertically extending inturned flange and at its front end a vertically extending flange bent upon itself to provide a frontally projecting box-like section inwardly offset from the panel to provide a right angular space or seat extending along the full vertical length of the panel for accommodating therein a vertically extending front leg for the table, b. a vertically disposed back panel extending transversely between the rear ends of said side panels, said back panel being provided at each of its opposite ends with a vertically extending right-angular flange having a terminal branch of which extends freely beyond the end of and is disposed in inwardly spaced parallel relation to said back panel to provide at each said end of said panel a right angular vertically extending space or seat in oppositely facing relation to the space or seat provided at the front end of the adjoining side panel for accommodating therein a vertically extending rear leg for the table, c. a plurality of vertically extending post members or legs of square cross section respectively nested in the vertically extending right-angular spaces or seats provided in the opposite ends of said back panel and the front ends of said side panels, and d. means for rigidly securing said side panels and said back panel to said posts or legs with said rear end flanges of said side panels respectively overlapping said freely extending terminal branches of the end flanges of said back panel and with said posts held secured against rotation about their vertical axes.
Claim 3
Dependent Claim
22 words
A construction as defined in claim 1 wherein said overlapping flanges of said panels are commonly secured to said posts or legs.
Claim 4
Dependent Claim
67 words
A construction as defined in claim 2 wherein said posts or lugs to which said back and side panels are commonly connected are respectively provided with at least one pair of vertically spaced nuT-engageable threaded studs projecting from one face thereof along lines paralleling the planes of said side panels for projection through correspondingly spaced openings provided in said overlapping flanges of said back and side panels.
Claim 5
Dependent Claim
71 words
A construction as defined in claim 3 wherein said posts or legs to which said back and side panels are commonly connected are respectively provided with at least a second pair of vertically spaced nut-engageable threaded studs projecting at right angles to said first-mentioned pair of studs and along lines parallel to the plane of said back panel for projection through openings provided in the opposite end flanges of said back.
Claim 6
Dependent Claim
65 words
A construction as defined in claim 1 wherein the posts or legs disposed in said spaces or seats provided at the front ends of said side panels are respectively provided with vertically spaced nut-engageable threaded studs which extend along lines paralleling the planes of said side panels for projection through correspondingly spaced openings provided in said vertically extending front end flanges of said side panels.
Claim 7
Dependent Claim
35 words
A construction as defined in claim 1 wherein said posts or legs are respectively provided at their top ends with flat anchoring plates for securing a table top in overlying relation to said supporting understructure.
Claim 8
Dependent Claim
47 words
A construction as defined in claim 6 wherein said anchoring plates are disposed in recesses provided in opposite end portions of the top edges of said back and side panels whereby the upper surfaces of said plates are flush with the upper edges of the interconnected panels.
Claim 9
Dependent Claim
31 words
A construction as defined in claim 1 wherein the opposed faces of said box-like sections at the front ends of said side panels pivotally receive therebetween an open-topped tiltable accessory tray.
Claim 10
Dependent Claim
33 words
A construction as defined in claim 8 wherein said accessory tray is provided with opposite projecting end pins which are respectively journalled for tilting movement of the tray about a horizontally extending axis.
Claim 11
Dependent Claim
48 words
A construction as defined in claim 8 including stop means for limiting tilting of said tray beyond its fully opened and closed positions accordingly as its center of gravity shifts from a point to the rear of its said axis to a point in front of said axis.
