Definitions

  • This invention relates to a take-down metal shelf structure comprising two lateral frames or panels each comprising U-sectioned registering vertical channels formed by bending twice at right angles the edges of the frame 01 panels, a pair of upper and lower cross members consisting of U-sectioned or channel elments secured at their ends by means of lugs on rack-forming channels extending at right angles to said cross members and so shaped and dimensioned as to permit their force fitting in said panel channels, shelves consisting of trays or plates, having their edges bent at right angles and forming a channel receiving at the corners locking devices adapted to permit their proper positioning on the frame structure by engaging locking devices into the racks of the vertical uprights.
  • the assembly operation particularly simple and requiring no fixation member, consists in fitting the racks into the upright channels; the rigidity of the assembly and the fastening of the shelves are obtained by means of collapsible locking devices.
  • the horizontal cross members and bracing members of the structure are secured at either end by channelsectioned lugs with only one rack length, the complementary rack length being secured permanently in the central portion of the upright channels, suitable lugs constituting the extension of each rack solid with a cross member to joint this rack element end to end with the element rigid with the upright.
  • Each shelf locking means housed in the channel portions of the shelf consists of a blade bent on itself with a gripping finger having one side adapted resiliently to engage catches formed in the lower side of the marginal portion of the shelf; these catches correspond to the retracted, preset and operative position of the locking device respectively.
  • FIGURE 1 is a perspective view showing the relative position of the component elements of the shelf during the assembly thereof.
  • FIGURES 2 and 3 are detail views showing the locking device of the shelf trays.
  • the shelf structure according to this invention comprises two registering identical rectangular lateral frames each consisting of a pair of vertical registering channeled uprights 61, 62 assembled by means of cross pieces 63 and provided at their ends with lugs 9.
  • Each shelf structure is completed by horizontal cross members 11.
  • Each of the cross members 11 comprises a transverse element 4-0 of channel cross-section and rack elements 17 rigidly fixed at opposite ends of the element 40 and perpendicular thereto.
  • the cross members 11 are assembled with the channeled uprights 61, 62 by pressing Patented Sept. 14, 1965 the rack elements 17 into end portions of the upright channels in which they are a press fit.
  • the rack elements 17 are cut to a predetermined length so as to butt end-to-end with rack elements which are secured in central portions of the channeled uprights 61 and 62.
  • Lugs 64 welded on the end portions of the channelshaped rack elements 17 are received in the opposite ends of the intermediate rack elements 65 to provide an interlocking of the rack elements.
  • the locking device 28 for supporting the shelf trays 21 while preserving the necessary rigidity of the assembly consists essentially of a V-shaped bent blade 66 of resilient material which is slidably retained in the channel resulting from the double bending of the marginal portion 22 of the shelf.
  • the blade 66 is a width to fit in the channel between the shelf and marginal portion 22.
  • One leg 66a of the blade slidably engages the bottom 67 of the channel while a second leg 66b resiliently engages one or more catches 70, 71 and 72 formed by small protuberance struck from the marginal portion 22 of the shelf.
  • a nose portion 66c of the locking device is adapted to project out through an opening in the channel and is preferably offset from the leg portion 66a as seen in FIG. 3.
  • a tab portion 68 is bent outwardly at approximately right angles to provide a finger grip for sliding the blade 66 in the channel.
  • the tab 68 is of reduced width and forms a shoulder 69 adapted to engage between the catches 70, 71, 72 to hold the blade in a retracted position or in a locking position in which the nose portion 66c projects outwardly as shown in FIGS. 2 and 3 to engage in a selected opening in one of the rack elements 17, 65 to hold the shelf in selected position.
  • the shoulder 69 is releasable from the catches 70, 71, 72 by pushing inwardly on the finger tab 68 whereupon the blade can be slid from one position to another, or completely released by sliding the blade to the left as viewed in FIGS. 2 and 3.
  • each locking device comprising a flexible elastic blade having a width slightly less than the distance between said horizontal walls of said channel and bent back on itself in the form of a V with a nose portion formed by the point of said V, a first leg portion slidably engaging said vertical wall of said channel and a second leg portion having at its end an outwardly bent tab portion projecting away from said vertical wall of the channel and of less Width than the said branches and a plurality of catches formed by stamped out portions in at least one of said horizontal walls of said channel, said catches being spaced from said vertical wall of said channel and slidably retaining said locking device between said catches and said vertical wall of said channel for sliding movement between a locking
  • each of said locking devices comprising a flexible elastic blade having a width slightly less than the depth of said channel and bent back on itself in the form of a V with a nose portion formed by the point of said V, a first leg portion slidably engaging said vertical wall of said channel adjacent a corner of said shelf with said nose portion toward said corner and a second leg portion having at its end an outwardly bent tab portion projecting away from said vertical wall of the channel and having an outer portion of reduced width to form a shoulder, and retaining means projecting into said channel for slidably retaining said locking device between said retaining means and said vertical wall of the channel for sliding movement between a retracted position and a
  • said retaining means comprises three spaced protuberances formed by inwardly stamped portions of said inwardly bent marginal portion, said shoulder on said locking device being releasably engageable with said protuberances to hold said locking device in said retracted and locking positions and said second leg being flexible inwardly to release said locking device for sliding movement from one said position to another.
