  • Hafer l 5 7 1 ABSTRACT A material handling cart 0f the foldablc type having a rear wall supported on a pair of casters, a pair of foldable side walls each supported on one individual caster, and middle and lower shelves each hinged to the rear wall so that each can be folded up against the rear wall before the side walls are folded around them.
  • Each extension panel is slidable underneath its associated shelf into a fully stored position, or it may be pulled partially forward to act as a shelf extension, or when pulled to a fully forward position it may be pivoted upward to provide a front wall enclosing the space above the shelf.
  • Material handling apparatus must meet many and diverse requirements which vary in numerous details depending upon the particular application. Some of the important factors involved are manufacturing cost, the ease and convenience of transporting and storing the apparatus when it is not in use, and the effectiveness of the apparatus when it is being used for its intended purpose.
  • the prior art is replete with numerous examples of storage shelf structures, and is also replete with numerous examples of wheeled vehicles such as carts and the like which are used for material handling purposes.
  • the preferred embodiment of the present invention relates to a wheeled cart which incorporates a shelf structure.
  • One principal object of the invention is to provide an improvement in the collapsible or foldable type of material handling cart.
  • Another separate and distinct object of the invention is to provide an improvement in a shelf structure, which improvement will be of value irrespective of whether or not the shelf structure is associated with a wheeled vehieled.
  • an improved shelf structure is provided by incorporating guideway means beneath the respective ends of a normally horizontally disposed rectangular shelf.
  • a movable panel is also provided which is adapted to be supported from the guideway means, beneath the shelf. In one position the panel may be entirely stored underneath the shelf; in another position it may be moved partially forward so as to provide a horizontal shelf extension; in yet another position the panel is moved to an extreme forward position and is pivoted upward so as to enclose the space about the shelf.
  • a collapsible or foldable material handling cart which has two vertically spaced shelves, and a movable panel associated with each of the shelves.
  • the movable panel may be stored beneath its respective shelf, may be moved to a partially forward position in which it acts as a shelf extension, or may be moved to an entirely forward position and pivoted upward so as to enclose the space above the shelf.

  • FIG. 13 is a perspective view of the material handling cart showing still a third position of the shelves and movable panels.
  • FIG. 14 is a cross-sectional view taken on the line 14-14 of FIG. 13.
  • FIGS. 1 to 14, inclusive illustrating the presently preferred form of the invention.
  • the novelty of the present invention resides in a movable panel associated with a shelf, which could be used in other material storage or material handling applications but is presently illustrated in conjunction with a collapsible material handling cart.
  • the general arrangement of the collapsible cart is well-known in the art and will be described briefly and in rather general terms, since a more specific description would serve no useful purpose.
  • the collapsible cart 10 includes a rear wall 12 and a pair of foldable side walls 20, 30.
  • the rear wall 12 has bent-over edges I3, 14 which give the rear wall a shallow U-shaped configuration.
  • Side wall 20 is attached to the edge 13 by means of a vertically spaced set of hinges l5, and in similar fashion the side wall 30 is attached to the rear wall edge 14 by means of a vertically spaced set of hinges I6.
  • a pair of casters 17, 18 are mounted by means of respective swivels from corresponding lower corners of the rear wall 12.
  • Casters 21, 31 are attached to the lowermost outer edges of the side walls 20 and 30, respectively.
  • the side walls When the side walls are expanded to their operative position, as shown in FIGS. 1, 6, and 13, the side walls together with the rear wall form a frame structure comprised ofa plurality of vertical tubes and which has a U-shaped cross-sectional configuration in the horizontal plane.
  • the side walls 20, 30 may be folded in toward the rear wall 12, and
  • the folding cart 10 also includes a bottom shelf or deck 40, and a center shelf 60.
  • Bottom shelf 40 is attached to the lowermost frame member of rear wall 12 by means of a pair of hinges 19, and may therefore occupy either an operative horizontal position as shown in the drawings or else may be folded vertically upward to a folding position in which it is latched against the rear wall 12.
  • the center shelf 60 is attached to rear wall 12 by means of hinges 19a, thus permitting the shelf to be either horizontally disposed in operative position or folded to a vertical position for transportation or storage purposes.
  • FIG. 1 shows the horizontal position of center shelf 60 while FIGS. 6 and 13 show its raised position.
  • movable panels are identical to each other in their construction, and hence the same reference numerals will be used throughout for identifying the corresponding parts of these panels.
  • each of the movable panels includes a rectangular frame 70 having a pair of laterally projecting posts 71a, 7117 on its rearward edge, and a pair of laterally projecting pins 72a, 7217 on its forward edge.
  • the structure and function of both the posts and the pins will now be described in some detail.
  • the frame 70 includes a plurality of laterally spaced tubular members or ribs 75 which extend in a direction perpendicular to the rear wall 12 of the cart 10.
  • Tubular members 75 are of approximately square crosssectional configuration.
  • Another square tubular member 71 forms a cross-member which extends across the rearward ends of the members 75, being welded to the upper surfaces thereof, as best seen in FIG. 5.
  • the length of tubular member 71 is greater than the lateral extent of the frame members 75, and hence the projecting ends of tubular member 71 provide the posts 71a, 7lb as previously described.
  • the posts 710 and 71b have several different functions or purposes.
  • One function or purpose is to provide vertical support for the rearward edge of the moving panel when it is in a fully stored position underneath its associated shelf (see FIG. 2).
  • a second function is to provide a cantilever support for the movable frame when in its partially extended position (see FIG. 3). In this position the upward movement of tubular member 71 is precluded by frame members 41, 42 of the corresponding shelf (see FIG. 4).
  • a third function of the posts 41a, 4 lb is to provide a pivotal support for the rearward edge of the moving panel, when in its fully forward position. so that the moving panel can be raised to a vertical position in which it encloses the space above its associated shelf.
  • FIG. 6 illustrates the vertical position of moving panel MP1.
  • tubular member 72 Across the front end of the tubular members 75 there is another tubular member 72, located in the same plane as the members 75 and, which is welded to their respective ends.
  • Pins 72a, 72b are attached to the re spective outer ends of the tubular member 72 (See detail views as shown in FIGS. 9 and 12).
  • the tubular member 72 is used as a convenient handle for sliding the movable frame back and forth between its fully stored position, its partially forward position in which it acts as a shelf extension, and its fully forward position in which it acts as a vertical forward wall.
  • the function of the pins 72a, 72b is to cooperate with latches 22, 32 attached to the respective side walls 20, 30, for holding the movable panel in its vertical position. (See FIGS. 7, l l, and 12).
  • Each of the shelves 40, 60 is provided with appropriate guideway means for supporting the corresponding movable panel. Since these guideway structures are identical for both of the shelves, the same reference nu merals will be used throughout for the parts.
  • a pair of outer guide members 43, 44 are of L-shaped cross-sectional configuration and have their upper edges secured to respective tubular members 41, 42 which form a part of the corresponding shelf structure and extend in a direction perpendicular to the rear wall 12 of the cart.
  • the lower portions of the guide members 43, 44 are horizontally disposed and occupy the same horizontal plane being turned inwardly toward each other.
  • the outermost ones of the tubular members or ribs of the associated movable panel are slidingly rested upon the inner and upper surfaces of the lower portions of the guide members 43, 44.
  • guideways 45, 46 which are also of L-shaped configuration.
  • the upper longitudinal edges of these members are welded to the under surfaces of the shelf frame members 41, 42, respectively.
  • the lower portions of the guideways 45, 46 occupy a common horizontal plane, and are turned inwardly towards each other so as to provide sliding support for the posts 71a, 71b of the movable panel.
  • the guide members 43, 44 do not extend the full width of the associated shelf, but are attached beneath the forward edge portion thereof. (See FIGS. 3 and 5).
  • the guideways 45, 46 do extend the full front to rear distance of the shelf. (See FIG. 3 where it is clearly shown that the closed end 45a of guideway 45 is located somewhat forwardly of the most forward edge of the shelf 60).
  • Each movable panel is also provided with stops for preventing it from being accidentally dislodged from its stored position.
  • a pair of stops 77 are welded to the undersurfaces of the outermost ones of the members 75, near the forward edge of the movable panel but yet some distance back from the front edge bar 72.
  • the position of the stops 77 is also clearly shown in FIG. 7.
  • the stops 77 are located rearwardly of the guide members 43, 44. The rearward end edges of the guides 43, 44, therefore act as coacting stops. (See FIG. 2).
  • FIG. 13 illustrates a very unique way in which the apparatus of the present invention may be used.
  • the center shelf 60 is raised to a vertical position where it is folded back against the rear wall 12.
  • Movable panel MP2 rather than simply being extended out or being rotated up relative to the shelf, is instead rotated downward relative to the shelf.
  • movable panel MP2 is able to occupy a horizontal position, with pins 72a, 72b being latched by the latches 22, 32, respectively.
  • Movable panel MP2 therefore acts as a top shelf or lid for the cart 10, with the whole interior of the cart being open and accessible from the front. This configuration of the cart is particularly useful when transporting packages of exceptional vertical height.
  • Each shelf when occupying its horizontal position is supported by studs 25, 35, attached to the inner sur faces of the side walls 20, 30, respectively.
  • a unique latch mechanism is provided forlatching each of the shelves in its vertical position. This is a selfoperating, gravity operated latch. There are only two of these latches, one for each of the shelves, and both of these latches are attached to the end portion 14 of rear wall 12.
  • Each of the gravity latches L includes an inclined plane 81, an L-shaped bolt 82, and a collar 83 for holding the bolt.
  • Latch L is also shown in FIG. 8.
  • the collar 83 is a square tubular member of relatively short length and is vertically disposed. It is attached as by welding to one vertical surface of the square tubular post 14a.
  • Post 14a is a vertically extending post which constitutes the forward-most portion of the rearwall edge 14 (See FIG. 1).
  • the collar 83 is attached to the rearward side of post 14a, away from the side wall 30.
  • the L-shaped bolt 82 has a vertical shank which extends upward through the collar 83, and also has a horizontal shank which extends horizontally from the lowermost extremity of the vertical shank.
  • the exterior corner surface of the L- shaped bolt 82 is rounded.
  • Sloping cam member 81 is welded to the same surface of post 14a, some distance below the collar 83. The cam 81 slopes so that its low ermost end is directed toward the interior of the cart, i.e., toward the opposite side edge 13 of rear wall 12.
  • FIG. 10 The operation of the gravity latch is illustrated in FIG. 10.
  • shelf 60 When shelf 60 is swung vertically upward to its folded position it engages the horizontal arm of the bolt 82, swinging it back to the dotted line position 82. Shelf 60 is moved further back toward rear wall 12, to the dotted line position 60. This permits the horizontal leg of bolt 82 to return to its solid line position as shown in FIG. 10. Shelf 60, when released by the hand of the operator. may then pivot outward where it is retained by the leg of bolt 82, as shown in solid lines in FIG. 10. In order to release the shelf it is necessary to push both the bolt 82 and the shelf 60 toward the rear wall 12, holding the bolt in the dotted line position as shown by 82 until the shelf is able to clear it upon returning towards its unfolded or horizontal position.
  • the advantage of this gravity latch is that the mere act of raising the shelf to its vertical position causes the latch to operate, thus preventing an inadvertent dropping of the shelf back to its horizontal position.
