Definitions

  • the bent end portions of the wire form vertically disposed protruding loop portions which extend UNITED STATES PATENTS into grooves in the corner posts and are positioned 1,829,009 10/1931 iviadsen 108/109 X and suppgrted vertically by pins inserted in horizontal holes intersecting the grooves in the corner posts.
  • the present invention relates to shelving and more particularly to shelving structures in which the ends of the shelves are adjustably connected with vertical corner posts.
  • Adjustable shelving structures are known in which the shelves are supported at selected vertical positions by means of hooks or fittings which fit into the grooves or recessesin the corner posts and support the shelves at the corners.
  • one type of fitting comprises a small angle bracket having a pin portion fitting into a hole in the corner post.
  • the shelf When the shelf is supported only at the corners, the shelf itself must have sufficient structural strength in a widthwise direction to support the load of material placed on the shelf. This requires the shelves to be made of a strong and relatively heavy material which increases the weight and cost of the shelving structure.
  • the hooks, brackets and other fittings heretofore used in adjustable shelving structures are relatively expensive and are frequently inconvenient to use.
  • a very simple and easy to assemble shelving structure is achieved by supporting the end of the shelf by a piece of rigid wire which extends beneath and across the shelf and has end portions which are bent upwardly and inwardly and enter holes in the front and back edges of the shelf.
  • the bends of the wire form vertically disposed protruding loop portions whichenter vertical grooves in the corner posts and are supported by pins inserted in holes intersecting the grooves.
  • the wire liesin a groove formed in the bottomof the shelf.
  • FIG. 1 is a vertical section through one end of a shelf and two corner posts.
  • FIG. 2 is a horizontal section of one of the-corner posts taken approximately on the line Il-II of FIG. 1 with a corner portion of a shelf shown in plane view and;
  • FIG. 3 is a horizontal section and partial plan view similar to FIG. 2 but showing a modification.
  • FIG. 1 shows one end of a shelf 1 fitted between two corner posts 2,3 and supported by means of a rigid wire 4.
  • the two corner posts are held in fixed spaced relation to one another, for example by a panel or by cross rails.
  • the rigid wire 4 extends the full width of the shelf 1 and fits in a groove 6 on the under-side of the shelf so that the wire is approximately flush with the bottom surface of the shelf. End portions of the wire 4 are bent upwardly and inwardly with the two inturned ends 7 and 8' of the wire received in holes 9 and 10 in the front and back edges respectively of the shelf 1.
  • the bent portions of the wire form loop portions 11 and 12 which protrude at opposite edges of the shelf and are received in vertical grooves 13 and 14 formed in the corner posts 2 and 3. It will be seen that the loop portions 11 and 12 are of U-shaped configuration with approximately parallel horizontal portions connected by an approximately vertical portion.
  • the protruding loop portions 11 and 12 of the rigid wire 4 rests on and are vertically positioned by pins 15 and 16 which are fitted into horizontal holes 17 and 18 which are provided in the corner posts 2 and 3 in such position as to intersect the grooves 13 and 14.
  • a number of holes 17 and 18 are provided at spaced intervals along the corner posts 2 and 3.
  • the supporting wire 4 while being somewhat resilient is sufficiently rigid to provide support for the shelf 1 throughout its width.
  • the shelf can be made of relatively inexpensive material such as chipboard.
  • at least one of the holes 7,8 provided in the edges of the shelf has a depth at least equal to the distance between the respective end 7 or 8 of the wire 4 and the vertical portion of the respective protruding loop portion of the wire 11 or 12.
  • the distance between the vertical portion of the protruding loop 11 or 12 to the opposite end 8 or 7 of the wire 4 is approximately equal to the width of the shelf. In the construction shown in FIG. 1, both holes are of the same depth.
  • the wire 4 is assembled on the shelf by inserting one end portion 7 or 8 as far as it will go in the respective hole 9 or 10 so as to permit insertion of the opposite end of the wire in the opposite hole, whereupon the wire is brought to an approximately centered position.
  • the wire 4 is held in approximately centered position by engagement with the bottoms of the grooves 13 and 14.
  • the distance between the bottoms of the opposite grooves should be only slightly more than the overall length between opposite bent-up portions of the wire 4.
  • the wire 4 ' is thereby held against longitudinal movement sufficient to release wither of the inturned end portions 7 and 8 from the respective holes 9 and 10.
  • Each of the corner posts 2,3 is preferably provided with a second groove 24 which is parallel to and spaced from the groove 14. This permits adjustability by positioning the shelf support in either of the grooves. Alternatively, a panel can be fitted into the outer grooves 24. To allow this, the cross rails between the corner posts 2 and 3 are not thicker than the distance between the adjacent sides of the grooves 14 and 24 in the corner posts.
  • the construction illustrated in FlG. 3 is like that of FIGS. 1 and 2 except that the shelf 1 is provided at each corner with a right angle recess having a surface 19 which faces the grooved face of the corner post and a second face which is parallel to the support wire 4 and faces a surface 21 of the corner post.
  • the distance between the surface 20 and the adjacent side of the protruding loop portion of the support wire 4 is slightly less than the distance between the surface 21 and the adjacent side of the groove 14 of the corner post.
  • the surface 20 is thereby held resiliently against the surface 21 of the corner post by the inherent resilience of the support wire 4.
  • a shelving structure comprising vertical corner posts, a shelf having an end portion disposed between two of said corner posts, said corner posts having longitudinally extending grooves in faces facing said shelf, and means for supporting said shelf comprising a piece of rigid wire extending across under said end portion of the shelf and having end portions bent upwardly and entering holes in front and back edges of the shelf, said upwardly bent end portions of said wire having vertically disposed protruding loop portions which are received in said grooves in said corner posts, and means in said grooves for positioning and vertically supporting said loop portions.
  • a shelving structure according to claim 1 in which said wire fits in a groove on the under-side of said shelf.
  • a shelving structure in which at least one of said holes in the shelf edges extends inwardly of the respective end of said wire, and in which the distance between the other end of said wire and the opposite upwardly bent end portion of the wire is approximately equal to the width of said shelf whereby said wire is assembled with said shelf by inserting an end of said wire into said one hole, moving said wire laterally of said shelf until the opposite end portion of said wire clears the opposite edge of the shelf and inserting said opposite end portion in the hole in said opposite edge of the shelf.
  • any gap between the upwardly bent end portion of said wire and the bottom of the groove in which it is received is less than the distance the respective end portion enters the respective hole in the shelf when said wire is in symmetrical position relative to said shelf.
  • each of said corner posts is provided with holes intersecting said grooves and in which said positioning said supporting means comprises pins inserted in selected ones of said holes in said corner posts and engaged by said protruding loop portions of said wire.
  • a shelving structure in which a corner of said shelf is notched to receive said corner post, said notch having a face that is parallel to said wire and is resiliently pressed against a corresponding face of said corner post by engagement of said protruding loop portion in said groove in the corner post.
