BY C arL {0 ATTORNEY 1 GARBAGE RECEPTACLE This invention relates to a garbage receptacle, in particular for use in hospitals, doctors surgeries, bathrooms, shops, etc., in the form of a chest-like container with closable opening for throwing in garbage, the interior of the receptacle being accessible through a tilting or swinging side door and accommodatinga flexible garbage sack which is suspended in a holding frame arranged on the inside of the door so that it can be taken out and changed; the holding frame incorporates a device allowing the neck of the sack to be tied mechanically.

The garbage receptacle according to the invention has the advantage that where the garbage is to be removed in sacks, as is very often the case atthe present time, it does not have to be transferred or emptied into such sacks from a pail. Another advantage of the invention is that the subsequent tying of the sacks is facilitated by constricting the neck of the sack mechanically.

The above and other features of my invention will now be described in detail with reference to the accompanying drawing which shows by way of example some preferred embodiments incorporating the invention, and wherein:

FIG. 1 is a vertical section of a closed garbage receptbroken lines in FIG. 4. Numeral l2 denotes a garter coil springwhich, as best shown by FIG. 2, runs along the inner periphery of the rectangular sack-holding frame 11. At the four comers of the tensioned garter spring 12, flexible but practically inelastic pulling elements l3 engage, such as nylon cords, for example. These are led at the comers of the holding frame 11 over a pulley 14 to a slide 16 which is held by a catch spring 17 in the position shown in FIGS. 1 and 3. The door'9 has jointed thereto a retaining rod 39 which is led through a hole in the front wall of the receptacle and bent over to form a hook at the end. As shown in FIG. 4, rod 39 arrests the swing of the door in its outermost position. Instead of this retaining rod a flexible element, such as a small chain or a nylon cord, might of course be used.

The holding frame 11 serves to take a flexible garbage sack 18 whose mouth is wrapped over the sides of the holding frame 1 1, as shown in FIGS. 1 and 3. To immobilize the edge of the sack opening, frame 11 may be provided with spikes 11a onto which the mouth of the sack wrapped over the frame 11 can be pushed. To

able according to a first embodiment, taken along the line I I of FIG. 2;

FIG. 2 is a horizontal section taken along the line II II of FIG. 1;

FIG. 3 is a further vertical section of the closed garbage receptable taken along the line III III of FIG.

FIG. 4 is a vertical section of the openedv garbage receptable, similar to FIG. 1; I

FIG. 5 is a sectional view taken along the line V V of FIG. 4; i

FIG. 6 is a sectional view taken along the line VI-VI of FIG. 4;

FIG. 7 shows a top plan view of an ancillary for fixing the neck of the sack on a holding frame;

FIG. 8 is a detail view of a modification of the device of FIG. 1;

FIG. 9 is a perspective representation of a further modification of the sack-holding frame;

FIG. 10 shows a top plan view of the sack-holding frame shown in FIG. 9;

FIG. 11 is a diagrammatic representation of a cable control with pedal for operating the hinged lid of the receptacle by foot to expose the garbage opening; and

FIG. 12 is another embodiment of a garbage receptacle according to my invention.

hingedly mounted to pivot on a horizontal axis 8 in the embodiment illustrated. On the inside of the door a rigid rectangular sack-holding frame 11 is secured to a bracket 10 so as to pivot on the top edge of the door. The holding frame is shown in its swung-out position in support the bottom of the sack and carry its weight, door 9 has fixed thereto a vertically adjustable base board 19.

Arranged on the side walls of the receptacle are carrying grips 20, a knob 21 being disposed on the outside of the door 9.

With hinged lid 6 dropping inwardly oncoming garbage passes straight into the opened sack 18. Upon releasing the lid 6 it jumps straight back into the closed position of FIG. 1, owing to its spring or weight loading, so that dust particles and unpleasant smells given off by the garbage in the receptacle are not allowed to escape.

When the garbage sack is full and has to be taken out of the receptacle and replaced by a new sack, the tilting door 9 is swung out into the position of FIG. 4 and the mouth 18a of the sack is released from the holding frame 11. Upon releasing the catch spring 17, the slide 16 is pushed up from the position shown in FIG. 1 to that of FIG. 4. This allows the tensioned garter spring 12 to contract, thereby constricting the neck of the sack, as visible from FIGS. 4 to 6. The neck of the sack can thereupon be tied by the usual means, such as twine, wire or a clip. To ensure that such tying material is always at hand, a box containing twine, wire or clips may be mounted, say, on the inside of the door. On swinging the holding frame 11 out into the position shown chain dotted in FIG. 4, the full sack can be readily taken out therefrom.

Instead of the spikes 11a in FIG. 8, resilient clamps or spring-loaded holding flaps 54 (FIG. 12) might be used to secure the crimped over rim of the sack mouth 18a to the holdingframe 11. FIG. 7 shows another gripping device, which is a frame 22 pushed from above onto frame 11. One of its sides has a gap 22a which is closed by a tension coil spring 23 enabling frame 22 to be expanded elastically so as to be easily pushed over the holding frame 11.

FIGS. 9 and 10 represent a modification of the holding frame shown in FIGS. 1 to 6. On the actual holding frame 24, two elbow rods 27.and 28 are pivoted at 25 and 26 so as to swivel in the plane of the frame. Tension springs 29 and 30 engage the ends of the elbow rods projecting beyond the

pivots

25 and 26, thus tending to hold the

elbow rods

27 and 28 in the positions shown in FIG. 10, i.e., crossing or overlapping in the middle of the frame. The

vertices

31 and 32 of

rods

25 and 26 have fixed thereto

flexible drawing elements

33 and 34 that are through

eyelets

36 and 38 at opposite comers 35 and 35' of the frame, and through a further eyelet 37, to the slide 16 (FIG. 1). The position of the elbow rods shown in solid lines in FIG. 10 and chain dotted in FIG. 9 corresponds to the contracted state of the spring 12 with the neck of the sack drawn together as shown in FIGS. 4 to 6. For reopening this closure mechanism, the slide 16 connected to the

drawing elements

33 and 34 is moved into the position of FIG. 1, thereby swinging the elbow rods into the position shown in solid lines in FIG. 9 and chain dotted in FIG. 20.

Instead of providing the receptacle 1 with fixed feet, it can also be made mobile or else be designed for mounting on a wall.

Alternatively it is possible to support the garbage sack by at least one compression coil spring instead of the base board 19, so that the height of the sack is selfregulated by its own weight.

In the embodiment illustrated in FIGS. 1 t 8, the hinged lid 6 must be operated or moved by hand to expose the opening 4 for throwing in garbage. It is also possible to operate the lid with a pedal, however. FIG. 11 diagrammatically shows such an arrangement, the receptacle being partly omitted for clearness of illustration. As before a lid 6 is swingable about a pivot 5. At B an edge of the lid is engaged by a rod spring 39 which is mounted on the lid pivot so as to swing in a vertical plane. Rod spring 39 passes through a hole 40 in one end of a lever 41 whose opposite extremity 42 is rotatable about a horizontal axis on a fixed part of the receptacle. A further rod spring 43 tends to swing the lever 41 in the direction of the arrow A. Numeral 44 designates a tension spring having one end fixed to a lug 45 of lever 41, and having its other end joined to a cord 46 which leads via a deflecting point 47 to a lever arm 48 secured to a hollow shaft 49. This hollow shaft is mounted so as to turn in bearings, of which only one (50) is shown. A bell-crank lever 51 has one of its ends inserted in the hollow shaft 49 so as to be directly connected therewith, though disconnectable, and has a pedal 52 fixed to its other end. The connection between hollow shaft 49 and bell crank lever 51 is made releasable so that the pedal located at the right-hand side of the receptacle in this case may be inserted into the hollow shaft on the left-hand side of the receptacle, if necessary. For transporting the garbage receptacle,

pedal assembly

51, 52 may be removed, or else raised toward the receptacle as indicated by the arrow C.

On pressing the pedal in the direction of the arrow D, the lever arm 48 is swung in the direction of the arrow E and the cord 46 is moved in the sense of the arrow F. The force and motion set up in the cord are in part transmitted through the spring 44 to the lever arm 41 which is turned clockwise on its pivot 42. The pivotal motion of pedal 52 is transmitted, greatly amplified, by lever 41 to the rod spring 39, thus lowering the hinged lid 6 in the direction of the arrow G and exposing the entrance opening into the receptacle.

Without spring 44 if the garbage sack were full and the pedal were operated particularly forcefully there would be a danger that the hinged lid might be obstructed by the sack and be unable to open fully, resulting in the lid being bent or damaged. This danger is countered by providing the spring 44, because the same does not transmit the full force applied at pedal 52 to the lever arm 44, but only a part thereof as determined by its elasticity. Spring 44 is dimensioned so as to keep this fractional force within limits that preclude damage to the hinged lid.

In the embodiment illustrated in FIG. 12, numeral 53 designates a sack holding frame of, say, rigid plastic which has resilient flaps 54 hinged to its ends, only one of them being visible. At 55 I have shown a holder joined to the frame 53 or else integral therewith. Molded in holder 55 are two open bearings 56, of which again only one is visible in FIG. 12. These bearings carry a pin 57 which acts as a roll holder adapted to receive a rolled-up strip 58 of garbage sacks 59 which has transverse perforations for tearing off the individual sacks one at a time, as may be obtained from commercial sources. The detached individual garbage sacks may be suspended from and fixed to the frame 53 in the aforedescribed manner. This arrangement has the advantage that fresh garbage sacks are always available just where they are needed.

In order to make further use of the throwaway shopping bags such as retail shops give their customers, pairs of notches 60 are arranged in the top edge of the sides of frame 53. Shopping bags can be suspended from these notches and be used again as garbage bags hanging on the frame by their handgrips.

A cover 61 is hingedly mounted on the sack holding frame 53 and upwardly swingable up to expose the opening for throwing in garbage. Also in this embodiment there is provided a tray 62 to carry the weight of the sack. This device is particularly suitable for mounting on a wall or the like, say, in a workshop or other industrial premises where garbage has to be disposed of.

Altematively, it is possible to have holding frame 53 and tray 62 combined with supports 63 and casters 64 (shown chain dotted) so that a mobile frame results. A garbage-sack receptacle of this kind is not tied to one place but may be positioned wherever it is needed.
