Definitions

  • This invention relates to a frame adapted to be axially collapsed by means of a turning movement, suitable in particular for display racks comprising a plurality of shelves arranged above each other.
  • the frame comprises uprights interconnecting the circumferential edges of shelves arranged above each other, which uprights are each composed of elements which are hingedly interconnected between successive shelves and are each connected to a shelf edge by means of a pivot which permits limited rotation of the upright element in a plane substantially tangential to the shelf edge.
  • the shelves are disposed above each other and the uprights are vertical columns whose constituent elements are in alignment.
  • the shelves are disposed substantially on top of each other and the uprights, viewed in a vertical projection, extend around the shelves as a polygon, each upright following an angular helix extending from a circumferential point of the bottommost shelf to a circumferential point of the topmost shelf.
  • the upright elements may be formed from sections having a good bending stiffness but a slight torsional stiffness.
  • the hinges interconnecting two upright elements can be so constructed that they exclusively permit changes of the angle between these elements in their common longitudinal median plane, so that the stability of a rack in erect position is not adversely affected by clearance in these hinges, and the flexibility required to enable each upright to extend along the angular helical path in the collapsed position of the rack can be provided by slight torsional resistance in the upright elements themselves.
  • a section having the desired bending stiffness and little torsional resistance is for instance a steel U-section having external dimensions of the order of 10x10 mm and a thickness of the material of the order of 0.5 mm.
  • the flanges of the section at the end of the first element may be recessed inwardly by the thickness of the material, so that when the hinge is in extended position, these flanges can accurately fit between the flanges of the second section. Further, the web of this second section may be extended so that it rests against the exterior of the first section when the hinge is in the extended position.
  • a constructively simple embodiment of the pivoted joint through which each upright element is connected to the edge of a shelf and which permits limited rotation of the upright element in a plane that is substantially tangential to the edge of the shelf is an embodiment in which two plastics members, one to be secured to a shelf edge and the other to an upright element, are capable of relative rotation while in surface-to-surface contact, limited by stops formed thereon.
  • the member to be secured to an upright element of U-shaped section may be formed as a substantially disc-shaped member with parallel recesses terminating in one side thereof, which recesses can receive with a proper fit the flanges of the U-section of the upright element, while on the opposite side there is formed a sliding surface which, in the assembled condition, is in abutment with the sliding surface of the other member, to be secured to the shelf edge.
  • the sliding surfaces of the pivot members are provided on a projecting and a countersunk portion, respectively, the countersunk sliding surface being surrounded by an annular rim for receiving said projecting portion with a sliding fit and the stop means being formed by at least one radial projection which is formed on the inside of the annular rim.
  • a display rack comprises shelves 1 having their edges 2 supported by uprights 3.
  • the uprights 3 are each composed of elements 4 which are interconnected between the shelves 1 by hinges 5.
  • the upright elements 4 are connected to the edges 2 of the different shelves by means of a pivot 6 of which one embodiment is shown in perspective in Fig. 7.
  • the upright elements 4 pivot relative to the shelf edges 2 in the pivots 6 and they hinge relative to each other in the hinges 5.
  • the uprights 3 must be capable of bending from the straight form of Fig. 1 into a helical shape as shown in Figs 2 and 3.
  • the upright elements 4 being formed as sections having a great bending stiffness and a comparatively slight torsional stiffness.
  • a section is shown in Figs. 4, 4a, and 5.
  • the section which is substantially U-shaped, comprises a web 7 and flanges 8. At both ends, holes 9, 10 are provided in the flanges for hinge pins (not shown).
  • the web 7 is formed with an extension 7a and the legs 8 are locally enlarged with an arcuate portion 8a.
  • the flanges 8 From the bottom view of Fig. 5 it appears that at the other, right-hand end the flanges 8 have been recessed inwards (8b), namely by the thickness of the material, so that at the hinges 5 (see Fig.
  • the recessed portions 8b accurately fit between the flanges 8 (in particular the enlarged portions 8a) of the adjacent upright element 4.
  • the extended web 7a gives additional stiffness to the hinge 5 by its abutment of web 7 of the adjacent element 4.
  • the enlarged portion 8a of the legs 8 of each section 3 gives additional resistance to twist in the hinge 5.
  • Figs 5 and 6 show a hole 11 provided centrally in each upright element 4, which hole serves to receive a screw bolt 12 which is part of the pivot 6 through which the upright elements 4 are secured to circumferential rings 2 of a shelf 1.
  • Fig. 7 One embodiment of the pivot joint is shown in Fig. 7.
  • FIG.6 which shows three upright elements 4 with angled hinges 5, for the three elements 4 shown to bend out of the flat plane and assume the helical shape of the uprights 4 shown in Figs 2 and 3, each element 4 twists in the manner indicated by the arrows P, while the portions of the upright elements 4 adjacent the hinges 5 in principle remain oriented in the median plane of each hinge 5.
  • each pivot 6 through which an upright element 4 is connected to the circumferential edge 2 of a shelf 1 is composed of two members 6A and 6B.
  • member 6A is to be secured to an upright element 4 and member 6B to a circumferential edge 2.
  • Member 6A is generally disc-shaped and has two recesses 13 provided on one side thereof for accurately fitting therein the legs 8 of the U-section of an upright element 4.
  • a sliding surface 14 is formed on a projecting portion 15.
  • the projecting portion 15 can be accurately fitted into an annular rim 16 of member 6B, which faces the member 6A in assembled position of the pivot 6, the annular rim 16 surrounding the sliding surface 17 of the member 6B.
  • Projecting inwards from the annular rim 16 are two stop lugs 18 having substantially radially directed stop surfaces 18a adapted for cooperation with the lateral faces 15a of member 6A to limit the angle of pivot permitted in each pivot 6 to a desired value.
  • member 6A further comprises two ribs 19 having end faces 19a disposed in the same plane as faces 20 on opposite sides of the projecting portion 15.
  • the projecting portion 15 of the pivot member 6A extends within the annular rim 16 of the member 6B, whereby the respective sliding surfaces 14 and 17 are in contact with each other while the surfaces 19a and 20 of the member 6A are disposed at a slight distance from the annular rim 16.
  • any tilting forces exerted on the pivot 6 are oppposed by the surfaces 19a and 20 of the member 6A and the oppositely disposed side of the annular rim 16 of the part 6B, which in that event will butt against each other.
  • the frame for a rack with shelves arranged above each other comprises uprights which are composed of elements which are connected to each other and to shelf edges and which are each formed from material having good bending stiffness and slight torsional stiffness, so that the rack is stable in the erect operative position and the uprights are permitted to extend substantially along helical lines around the shelves in axially collapsed position.
  • the shelves need not to be round as shown. They may in principle have any desired circumferential shape.
