Definitions

  • This invention relates to folding display frames, and more particularly, is concerned with a hub design for interconnecting pivotally joined rods into a frame.
  • Three-dimensional frameworks are well known in which a plurality of rod members are pivotally connected together to permit folding the framework into a compact closed form in which the rod members lie substantially parallel to each other.
  • Such folding frameworks have been used for racks to support covers, panels, and the like, some in dome-­shaped enclosures, in flat or curved display units, and in other types of rigid structures.
  • the rod members are pivotally joined at their ends to some type of hub so that the rods can be rotated relative to each other as the framework is adjusted between its open extended configuration and its closed compact storage configuration. Examples of such prior art folding frameworks are found in U.S. patents 4,471,548, 4,479,340, 4,512,097, 4,580,375 and 4,276,726.
  • One of the objectives of designing such frameworks is to make the structure light and compact in its folded condition to enhance the transportation and storage when the framework is not in use.
  • the framework when fully extended into its useful configuration, must be strong and fairly rigid.
  • the framework must not only be strong enough to give adequate support, but must withstand abuse, particularly when being folded and erected.
  • the present invention is directed to an improved framework design incorporating a unique hub that permits larger diameter thin-walled tubes to be pivotally connected in a strong, rigid joint. At the same time, the hub is very compact and light weight.
  • An added advantage of the present hub design is that it allows rod members of unequal length to be incorporated into the framework's array so that the height of the array may be, for example, less than the width while still permitting the structure to be folded effectively.
  • the framework incorporating the features of the present invention in its expanded or open state, consists of a grid of horizontal and vertical rod members forming an array of cubicles, each cubicle having a top, bottom and two-side frame sections, each frame section consisting of two rods or tubes pivotally joined to each other midway between their ends.
  • the rods terminate at each end in pivotally attached hubs. Adjacent cubicles in the array share common rods and hubs.
  • the rods of each frame section are rotated with respect to each other approximately 180° so that the opposite ends are brought into proximity.
  • the hubs are then closely packed in two groups at opposite ends of the substantially parallel rods.
  • Each hub is uniquely formed with a base and integrally formed flanges projecting from the base, the flanges being mutually perpendicular to each other.
  • a tubular rod is pivotally attached at each end to a hub flange, the pivot axes of tubes secured to one pair of diametrically opposite flanges being parallel and lying in a first common plane and the pivot axes of the tubes secured to the other pair of diametrically opposite flanges also being parallel but lying in a second common plane that is parallel to but offset from the first plane.
  • the numeral 10 indicates generally a folding framework shown in its open or expanded position.
  • the framework is constructed of a plurality of pairs of rods, in the form of thin-walled metal tubes, such as indicated at 12 and 14, the rods of each pair being pivotally joined together by a hinge pin 16.
  • the hinge pins 16 are located between the ends of the rods, allowing the rods to swivel with respect to each other in scissors-like fashion.
  • These rod pairs are joined to form a grid-like framework, with the multiple pairs of rods being arranged in vertical columns and horizontal rows.
  • the ends of the rods are joined by a plurality of identical hubs 18. As best shown in FIGS.
  • the framework in the expanded or open condition comprises a plurality of vertical columns, five of which are indicated respectively at 20, 22, 24, 26 and 28. These are joined by a plurality of horizontal rows, four of which are indicated at 30, 32, 34 and 36.
  • Each of the rows is made up of pairs of rods 12 and 14 in which the pivot connection 16 is located slightly off the center or mid position between the ends of its respective rods. Since all horizontal rods are of equal length, this causes the four pairs of rods joined in each row to assume a slightly arcuate shape. This shape gives more stability to the frame when it is resting on the floor or some other supporting surface.
  • the framework is locked in the expanded position shown in FIGS. 1 and 2 by a suitable latch mechanism which anchors one or more pairs of adjacent hubs 18 ⁇ and 18 ⁇ together.
  • a preferred latch for this purpose is shown in detail in FIG. 6.
  • One hub of the pair, such as indicated at 18, has a latch rod 40 which projects toward the adjacent hub 18 ⁇ of the pair.
  • the latch rod 40 engages a latch receptacle 42 which is rigidly secured to the hub 18 ⁇ .
  • the latch rod 40 enters a hole or bore 44 in the end of the latch receptacle 42 where the tapered end 46 of the rod 40 engages a spring-loaded latch pawl 48.
  • the latch pawl engages a notch 50 in the rod, securely locking the rod 40 in position in the latch receptacle 42.
  • the pawl which is pivotally supported to the receptacle by a pin 52 can be disengaged from the notch 50 to release the latch by pushing down on the opposite end 54 of the latch pawl 48.
  • the pawl is urged into engagement with the notch 50 by a suitable spring 51.
  • the latch mechanism shown in FIG. 6 need only be provided for one pair of hubs, preferably near the center of the framework grid. If greater rigidity is required, additional pairs of hubs can be provided with such a latch mechanism.
  • the entire framework can be collapsed or folded into the storage condition, as shown in FIG. 9.
  • the two rods 12 and 14 in each pair of such rods are rotated relative to each other about the connecting pivot 16, allowing each respective pair of hubs 18 ⁇ and 18 ⁇ to be moved apart until the rods 12 rotate almost 180 degrees relative to the other rods 14 of each pair.
  • all the hubs 18 ⁇ move into side-by-side engagement with each other, and all the hubs 18 ⁇ also move into engagement with each other.
  • the hubs are nested in two groups, each group, occupying an area which is limited by the size of the hubs.
  • a unique hub is provided which allows the hub to be substantially reduced in size without sacrificing rigidity and strength of the framework.
  • the hub design of the present invention provides for ease of assembly in pivotally attaching the rods to the hubs. Details of the hub design are shown more clearly in FIGS. 3-5.
  • the hub 18 is preferably molded of a suitable plastic material, but can be die-cast or otherwise formed of light weight metal.
  • the hub is formed with a base plate 60 which is generally square in outline with the corners rounded as shown in FIG. 5, and has a flat outer surface 62 from which projects a knob or flanged pin 64.
  • the knob 64 is used to mount various auxiliary devices to the framework.
  • the top surface 65 of the hub base plate 60 has four flanges or hinge plates 66, 68, 70 and 72 projecting perpendicularly therefrom. These flanges are offset from each other, as viewed in FIG. 5, so that each flange provides a flat surface, indicated respectively at 74, 76, 78 and 80. These surfaces lie in two mutually perpendicular planes. Thus, the surfaces 76 and 80 lie in a first common plane passing through the central axis 82 of the hub, while the surfaces 74 and 78 lie in a second common plane, also passing through the central axis 82 of the hub.
  • the flanges 68 and 72 project away from the base plate 60 a distance substantially twice that of the flanges 66 and 70.
  • High flanges 68 and 72 which are hereinafter referred to as "high" flanges, intersect in an enlarged central portion 84 having an opening or hole 86 into which the latch rod 40 or latch receptacle 42 may be press-­fitted or otherwise secured.
  • High flanges 68 and 72 are provided with holes 88 and 90 adapted to receive a pivot pin or rivet 91 which pivotally secures the end of a tubular rod to the hub flange.
  • the axes of the holes 88 and 90 are parallel to each other and lie in a common plane.
  • the flanges 66 and 70 are provided with holes 92 and 94 that are adapted to receive the hinge pins or rivets 91 associated with additional tubular rods.
  • the axes of the holes 92 and 94 are parallel to each other and lie in a common plane.
  • the plane of the holes 92 and 94 is offset from the plane of the holes 88 and 90 by a distance "A”.
  • the backsides of the high flanges 68 and 72 are undercut, as indicated at 96 and 98, respectively, to provide clearance for the ends of the rods pivotally attached to the low flanges as the rods are rotated about the axes of the holes 92 and 94.
  • each hub allows for the ends of four relatively large tubular rods to be pivotally attached to each hub by rivets 91.
  • the offset "A" allows ready access to all the rivets 91 of each hub by suitable riveting equipment.
  • the flange configuration allows the outer perimeter of the base plate 60 to be made approximately equal to twice the diameter of the tubular rods, thus permitting the hubs to be made extremely compact and to nest against each other in two groups in the folded condition of the framework, as illustrated in FIG. 9.
  • FIG. 7 shows a portion of the framework in a substantially folded position.
  • the spacing between the hubs in the horizontal rows is determined by the length of the rods 12 ⁇ and 14 ⁇ while the distance between the hubs in the vertical columns is determined by the length of the rods 12 ⁇ and 14 ⁇ .
  • the rods 12 ⁇ and 14 ⁇ are shorter, by an amount equal to 2A, than the horizontal rods 12 ⁇ and 14 ⁇ .
  • the openings or cubicles are not square but are rectangular, with the vertical dimension of each cubicle being smaller than the horizontal dimension by an amount substantially equal to 2A.
  • the high, low flange arrangement of the hubs allows the designer to modify the width-to-height ratio of the erected or expanded framework. It should be noted that if it is desired to construct the framework with all of the rods being of identical length, this can be accomplished merely by rotating the hubs 18 ⁇ 90° relative to the hubs 18 ⁇ .
  • the one feature of the present invention is an improved channel bar in which the sections are hinged together so that the channel bar can be attached as a unit or folded for storage.
  • the channel bar is shown in FIGS. 10 and 11 and includes three sections 80, 82 and 84. The sections 80 and 82 of the channel bar are joined by a link 86 pivotally attached to a hinged member 88 secured to the bar section 80 and a hinged member 90 secured to one end of the bar section 82.
  • the channel bar section 82 is connected to the channel bar section 84 by a hinge including a link 92 pivotally attached to a hinged plate 94 secured to the channel bar section 82 and a hinged plate 96 secured to the channel bar section 84.
  • the link 86 is longer than the link 92, allowing the channel bar section 82 to be folded between the channel bar sections 82 and 80 in the manner shown in FIG. 11.
  • the three sections of the channel bar are attached to the front of the framework by four key slots indicated at 100, 102, 104 and 106.
  • the key slots 102 and 104 are formed in the hinged members 90 and 96 respectively while the key slots 100 and 106 are formed in blocks 108 and 110 secured to the respective ends of the channel bar.
  • the key slots are open at one end and are arranged to engage knobs 64 on the front of the hubs of the framework.
  • the key slots are made progressively shorter from the top to the bottom of the channel bar as the key slot 100 is longer than the slot 102, the key slot 102 is longer than the slot 104, and the key slot 104 is longer than the slot 106.
  • the channel bar assembly can be lifted sufficiently to engage the key slot 102 at the next lower knob without disengaging the longer key slot 100.
  • the key slot 104 can be engaged with a knob without disengaging the slot 102.
  • the channel bars form a continuous vertical strip to which panels can be attached for covering the framework with a smooth, continuous display surface.
