Definitions

  • a trash compactor formed of a cabinet having a raised support floor upon which an open top trash bag is rested in upright position beneath a compacting ram, and a movable dolly formed of a roller supported frame arranged beneath the support floor and locked thereto by a releasable locking means.
  • a cabinet door is hingedly connected to the frame and has a bag support means upon which the bag is mounted. The door is arranged to tilt forwardly of the cabinet for raising the bag above the floor, for thereby removing the bag, door and frame as a unit, from the cabinet.
  • the door hinge includes a locking means which releasably locks the door in tilted position and simultaneously causes the frame locking member to unlock.
  • a manual control unlocks the door for swinging upright, thereby permitting the frame locking member to re-engage the cabinet door.
  • the invention herein relates to a trash compactor of the type shown, for example, in my earlier US. Pat. No. 3,438,32l issued Apr. 15, 1969.
  • a trash bag is arranged within a cabinet, beneath a compacting ram or piston, and is periodically lowered into the bag to compact trash thrown therein. When the bag is filled, it is removed and replaced.
  • the purpose of such devices are to compress together into a compact form, large quantities of loose trash such as may be found in cafeterias, restaurants, schools and the like.
  • the invention herein is concerned with a compactor construction wherein the bags are mounted upon removable dollys that can be easily engaged within the compactor cabinet and easily removed, and still permit a simple, strong construction to absorb the compacting loads.
  • the invention herein contemplates forming a compactor cabinet with a reinforced, load absorbing floor elevated above the floor upon which the cabinet is rested.
  • a bag supporting dolly in the form of a horizontal, roller mounted frame is arranged beneath the floor and the compactor door is hingedly connected to the frame and has support means for supporting a bag upright, beneath the compactor ram, with the bottom of the bag supported by the cabinet floor.
  • the door is tiltable forwardly about a horizontal axis, thus raising the bag off the floor, after it is filled, and easily permitting the dolly to be rolled out and away from the cabinet.
  • a locking means is provided which locks the frame to the floor structure and which automatically releases when the cabinet door is tilted and which again actuateswhen the door is raised into an upright position.
  • the locking means which is of simple construction, is formed of concealed, positively locking elements, to avoid possible accidental releases.
  • the resulting structure makes it possible to quickly and easily load a bag into the compactor and to remove the loaded bag with little physical effort, and roll the bag, upon the dolly to a disposal point where it may be easily removed.
  • FIG. 1 is a perspective view of the trash compactor herein, with the bag supporting door in upright or vertical position.
  • FIG. 6 is a fragmentary perspective view of a portion I of the locking mechanism.

  • FIG. 9 is a cross-sectional, side view, of the lower portion of the compactor with the bag holder upright.
  • FIG. 10 is a view similar to FIG. 9, but with the door and bag holder tilted for removal of the dolly from the cabinet.
  • FIG. 11 is a similar view to FIG. 10, showing the dolly removed from the cabinet and the door oppositely tilted for dumping the loaded bag.
  • FIG. 12 is a schematic view of the linkage system for operating the locking means.
  • FIG. 13 is an enlarged, cross-sectional view taken in the direction of arrows 1313 of the manual foot pedal operating means.
  • the compactor includes a large, open front, compactor cabinet 10, having a reinforced support floor 11 which is elevated above the floor upon which the cabinet rests by either suitable support legs or preferably by means of rollers or casters 12 mounted upon the cabinet.
  • the unit illustrated is a two-bag model, however, one bag may be omitted and the unit narrowed to contain only one bag.
  • An upright or vertical tiltable door 16 is provided with U-shaped, sheet metal, bag support frames or holders 17 having floors or base platforms 18, upon which the lower portion of the bag 15 rests.
  • the U-shaped bag supports are secured by brackets 19 to the door so that they are spaced from the door a short distance whereby the upper edges 20 of each of the bags may be turned over the tops of the U-shaped support frames for holding the bags to the frames.
  • the dolly consists of a horizontal frame 22 supported upon rollers or casters 23 and having an elongated, enlarged, front rail 24. At each end of the rail, an end or pivot plate 25 is secured in the vertical plane. Such plates are overlapped by door hinge plates 26 pivotally connected to the pivot plates by means of pins or axles 27 extending through openings 27a (see FIG. 6) in the pivot plates.
  • the hinge plates which are generally rounded in shape have extensions fastened by suitable rivets or screws 28 to the edges 29 of the door 16 near the bottom of the door so that the door may be tilted upon a horizontal axis.
  • the pivot plates 25 are each provided with openings 30 through which locking pins or bolts 31 extend.
  • These locking pins are each arranged within a cylindrically shaped housing 32 fastened to the respective pivot plates and containing spring 33 which provides a spring force upon the pin 31 to urge it outwardly of the hole or opening 30 in the pivot plate.
  • each of the pins are narrowed and attached to a tab 34 bent from and extending outwardly of U-shaped links 35 which are pivotally connected by pivot pins 36 to the rail 24.
  • Each of the U-shaped links are connected by an elongated rod 37 to a turn plate 38 located centrally of the rail and suitable connected thereto by means of a pivot pin 39.
  • the turn plate is rotated, as indicated by the arrows in FIG. 5, by means of an actuating pedal lever 40 pivotally connected by a pin 41 (see FIG. 13) to a bracket 42, secured to the rail 24 and having one end connected to a foot pedal 43 and the opposite end 44 extending through a slot 45 in the rail 24 and into a hole 46 in the turn plate.
  • actuating pedal lever 40 pivotally connected by a pin 41 (see FIG. 13) to a bracket 42, secured to the rail 24 and having one end connected to a foot pedal 43 and the opposite end 44 extending through a slot 45 in the rail 24 and into a hole 46 in the turn plate.
  • stepping upon the foot pedal 43 pivots the pedal lever 40 to rotate the turn plate 39 and thereby exert a pull upon each of the rods 37.
  • This in turn causes the U-shaped links to rotate about their pivot pins 36.
  • This retracts the locking pins 31 inwardly of the opening 30 in the pivot plates, as illustrated in FIG. 6.
  • FIG. 8 illustrates the
  • the normal position of the locking pins is the retracted position with the ends of the pins frictionally forced against or engaging the adjacent faces of the hinge plates connected to the door.
  • the door In this position, the door is upright or vertical.
  • notches or openings 47 formed in the hinge plate align with the locking pins 31 so that the pins are spring thrust outwardly into their extended position and into such notches or openings. This positively locks the hinge plates and thus, the door, in tilted position.
  • the locking pins remain in this position until such time as the pedal 43 is depressed by foot pressure to rotate the turn plate and thus rotate the U-shaped links 35 to retract the pins 31 out of the notches or openings in the hinge plates so that the door may be manually moved to its upright position again.
  • the horizontal frame 22 is normally located beneath the support foor of the cabinet and locked thereto by a locking mechanism which comprises a pair of elongated hook members 50 connected by pivot pins 51 to the side rails 'of the frame.
  • the hook members have a forward hook end 52 which engage with the lower portion of the support floor 11, namely, at the flanged or enlarged forward edge thereof.
  • the hooks are held in this locking engagement by spring pressure provided by an integral tab 53, depending from each hook member and connected by a suitable coil spring 54 to a bracket 55 mounted upon the frame. This is illustrated in FIGS. 6 and 7.
  • each of the hooks 50 are provided with bent flanges 56 which are engaged by forwardly bent flanges 57 formed on the lower ends of the nonpivoted leg of each of the U-shaped links 35.
  • the flanges 57 exert an upward force upon the rear ends of the hooks 50, causing them to pivot so that their hooked ends 52 move downwardly and disengage from the support floor.
  • the locking pins 31 are covered by the overlapping hinge plates 26 and the hooks 50 are upwardly extended to engage the bottom of the cabinet support floor for locking the dolly in place.
  • the locking pins immediately upon pulling the door forwardly so that it tilts, the locking pins extend outwardly through the notches or holes in the hinge plates, thus rotating the U-shaped links 35 to in turn lift up the rear ends of the hooks and pivot them for disengagement from the support floor for pulling the dolly away from the cabinet.
  • the user pushes the dolly back under the support floor, stepping on the foot pedal 43, then causes the locking pins to retract and permit the user of the equipment to swing the door in its vertical position where the hooks, due to the spring pressure, automatically engage the support floor and lock the dolly in place again.
  • the foot pedal may be pressed for retracting the locking pins and the door swung in the opposite direction so as to tilt the bag holders downwardly, as shown in FIG. 11. In. this position, the bags may be easily pulled out and removed.
