Abstract
Abstract A rack system for receiving and supporting items such as trays, pans, shelves, and the like comprising at least two pairs of vertically extending standards and a plurality of guide members extending between and connected to each pair of standards. Each end of each guide member is formed to provide upper and lower hook portions which engage, respectively, vertically spaced apart notches in a flange of the standard to which the end is connected. Each standard is preferably provided with a base plate so that it can be rigidly fastened to a floor. The upper end of each standard is preferably connected to a ceiling by means of a connector plate. Each standard is preferably a channel member, both flanges of which are provided with notches arranged to engage the said hook portions of a guide member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
366 words
A rack system for receiving and supporting items such as pans, shelves, and the like comprising at least two pairs of vertically extending standards, each standard including at least one vertically extending flange having a plurality of vertically spaced apart, horizontally extending notches provided therein, the flanges of each pair of standards lying generally in a common plane with the notches extending into the facing edges of the flanges and with corresponding notches in said flanges positioned at substantially the same elevation, a plurality of elongated guide members, each guide member extending between and connected to the flanges of one of said pairs of standards, each guide member providing an upwardly and longitudinally extending first flange portion and a forwardly and longitudinally extending second flange portion, each first flange portion providing, at each of its ends, an upper hook portion including a rearwardly and longitudinally extending third flange portion and, at the rear edge of said third flange portion, an upwardly and longitudinally extending fourth flange portion, and a lower hook portion including a rearwardly and longitudinally extending fifth flange portion and, at the rear edge of said fifth flange portion, a downwardly and longitudinally extending sixth flange portion, the upper and lower hook portions at each end of each guide member being engaged respectively in two of said notches in the flange of said standard to which the end of said guide member is connected, the upper and lower hook portion at each end of each guide member and the notches in which said hook portions are engaged being spaced apart and proportioned and designed so that said hook portions are disengaged from said notches by lifting the end of said guide member to elevate the lower edge of the sixth flange portion of said lower hook portion at that end above the lower edge of the notch in which said lower hook portion is engaged and then rocking said guide member about a longitudinally extending axis until the rearward edge of said third flange portion and the lower edge of said fourth flange portion of said upper hook portion can be moved forwardly through the notch in which the upper hook portion is engaged.
Claim 2
Dependent Claim
366 words
A rack system for receiving and supporting items such as pans, shelves, and the like comprising at least two pairs of vertically extending standards, each standard including at least one vertically extending flange having a plurality of vertically spaced apart, horizontally extending notches provided therein, the flanges of each pair of standards lying generally in a common plane with the notches extending into the facing edges of the flanges and with corresponding notches in said flanges positioned at substantially the same elevation, a plurality of elongated guide members, each guide member extending between and connected to the flanges of one of said pairs of standards, each guide member providing an upwardly and longitudinally extending first flange portion and a forwardly and longitudinally extending second flange portion, each first flange portion providing, at each of its ends, an upper hook portion including a rearwardly and longitudinally extending third flange portion and, at the rear edge of said third flange portion, an upwardly and longitudinally extending fourth flange portion, and a lower hook portion including a rearwardly and longitudinally extending fifth flange portion and, at the rear edge of said fifth flange portion, a downwardly and longitudinally extending sixth flange portion, the upper and lower hook portions at each end of each guide member being engaged respectively in two of said notches in the flange of said standard to which the end of said guide member is connected, the upper and lower hook portion at each end of each guide member and the notches in which said hook portions are engaged being spaced apart and proportioned and designed so that said hook portions are disengaged from said notches by lifting the end of said guide member to elevate the lower edge of the sixth flange portion of said lower hook portion at that end above the lower edge of the notch in which said lower hook portion is engaged and then rocking said guide member about a longitudinally extending axis until the rearward edge of said third flange portion and the lower edge of said fourth flange portion of said upper hook portion can be moved forwardly through the notch in which the upper hook portion is engaged.
Claim 3
Dependent Claim
35 words
The system of claim 1 in which each standard is adapted, at its lower end, to be supported by and connected to a floor and, at its upper end, to be connected to a ceiling.
Claim 4
Dependent Claim
122 words
The system of claim 2 in which each standard includes a vertically extending channel member, at least one flange of which is provided with said notches, each channel member having a perforation in its upper end, and including a horizontally extending perforated base plate rigidly fastened to the lower end of each standard to provide means for connecting the standard to a floor, and a connector plate for fastening the upper end of each standard to a ceiling, each connector plate providing a downwardly extending tongue having a perforation arranged to register with the perforation in the standard to which the plate is fastened, and a fastener element extending through the registering perforations of each connector plate and the standard connected thereto.
Claim 5
Dependent Claim
78 words
The system of claim 1 in which said two pairs of vertically extending standards are arranged side by side so that each guide member extending between one pair of standards will be parallel with and at the same elevation as a corresponding guide member extending between the other pair of standards, such corresponding guide members being allochirally arranged so that their second flange portions provide parallel runners on which a tray, shelf, or the like can be mounted.
Claim 6
Dependent Claim
89 words
The system of claim 4 including a plurality of shelf members, each shelf member being mounted on and supported by the second flange portions of corresponding guide members, each shelf member being generally rectangular and provided with down-turned flanges extending along its edges which extend perpendicularly to the second flange portions on which the shelf member is mounted, said down-turned flanges of each shelf member engaging the opposite ends of the second flange portions on which the shelf member is mounted to prevent sliding movement of the shelf member.
Claim 7
Dependent Claim
43 words
The system of claim 5 in which said shelf members are formed from a sheet of resin bonded fiber glass and each shelf member is formed to provide spaced apart ridges extending across said shelf member and parallel to its said down-turned edges.
Claim 8
Dependent Claim
47 words
The system of claim 4 in which the second flange portion of each of said allochirally arranged corresponding guide members is provided with a turned up, longitudinally extending outer edge portion, said edge portions providing runners for engaging the sides of shelves, trays, pans and the like.
Claim 9
Dependent Claim
74 words
The system of claim 1 in which each of said standards includes a vertically extending channel member, the vertically extending flanges of which are provided with said notches, whereby said guide members can be connected to either flange of each standard so that each standard can be used to support guide members having second flange portions extending outWardly to one side and guide members having second flange portions extending outwardly to the opposite side.
Claim 10
Dependent Claim
32 words
The system of claim 1 in which each of said guide members is a section of an aluminum extrusion formed to provide said first, second, third, fourth, fifth and sixth flange portions.
