4 Claims. (01. 312-270) This invention relates to waste receptacles,
and more particularly to a combined receptacle adapted to receive not only waste food or the like, normally at least potentially I odoriferous, and therefore preferably placed in a sealed container, but also combustible, or similar Waste materiaL such as paper and other articles or materials commonly placed in a waste basket. 7
Among the objects of this invention are togprovide a combinedwaste receptacle which provides ready access to either one, or both, of two Waste containers; to provide a receptacle in which access to a waste container'may be obtained by foot pressure; to providea receptacle in which a waste'container .is: moved from a. position". of storage or rest to an access or waste-receiving position; to provide such a container which may be locked in access position, but readily returned to storage position; to provide-a waste container for waste food products and. the like, which is adequately sealedduring storage; to provide such a Waste container which is automatically sealed upon being returned to storage position;'to provide a Waste receptacle which will contain a maximum volume of waste, with respect to the area of floor space occupied by the receptacle; and to provide a Waste receptacle which is sturdy, yet
relatively light in weight and simple in construction. .Additional. objects and. the novel' features of this invention will become apparent'from the description which follows, takeninconnection withthe accompanying drawings, in which:
.F'ig; 1 is -a front elevational view of a waste receptacle constructed in accordance with the present invention, with the parts in closed position;
Fig. 2 is a right side elevational view of thereceptacle of Fig. 1, showing the lower compar't ment and container in open position; 1
Fig. 3 is a vertical sectional-view taken substantiallyalong the line 3-'-3 of Figfl, lookingin the direction of the arrows; 1 Fig. 4 is a vertical sectional view, partly in elevation of the left side ofthe receptacle as shown inFig.2;
Fig. 5 is a left side elevational view'of the waste receptacle of the preceding views, showing the lower compartment and its removable container in partially open position; 1 r Fig. 6' is a horizontal sectional view'taken substantially along the line 66 of Fig. 4, looking in the direction of the arrows;- 7 f Fig. 7 is a -bottom plan view of the waste receptacle in open position and g Fig. 8 is avi'ew similar to Fig. '7, showing the 2 outwardly projected parts in their laterally shifted position to maintain said parts in open position. As shown in Figs. 1 and 2, a waste receptacle constructed in accordance with this invention for 'paper and similar combustible or substantially non-odoriferous and other waste bulky objects. The housing H is preferably formed of sheet metal or the like, and is square or rectangular in cross section but provided with rounded corners It for a purpose hereinafter setv forth. The upper and lower compartments are separated by a partition 15 on which upper waste container l3 rests, and '-which may be attached to the housing H. by spot welding or the like. The housing H is also provided at its upper, endwith .a hinged'lid it which, when in open position, permits access to upper Waste container l3.
The housin H is adapted to rest upon a floor or'similar supporting surface, and an outstanding feature, of this invention lies in-the fact that drawer D; instead of being pivoted or otherwise movable on or supported by housing H, moves inwardly and outwardly in a linear path through an opening l8 formed in housing H, as shown more clearly in Fig. 1, and is supported by front rollers I9 and rear rollers 26, substantially independently of the housing H; The possibility of tipping the .housingI-I is considerably minimized, and also' the possibility of the drawer D tipping or-falling out'of the housing is negligible. The drawer D includes a sheet metalfrohtll and bottom 22, suitably reinforced, asby a frame work 23 formed of channel or bar stock, and to which the roller brackets :24 are attached. In eifect, drawer-like -was'te food container D has its own carriage. I
The drawer D is moved outwardly by downward pressure on a foot pedal 25, which is pivoted on a pin 26 (Figs. 1 and 6) at one side of the housing H, while the drawer is returned to storageposition within the housing by a spring 21 which, as in Fig. 6, is attached at its rear end to the rear; wall of housingH andat its front end to a link 28.
Link 2B,.in turn, is pivoted at its forward e'nd on a pin 29 connecting link 28 with foot pedal 25, pin 29 moving in an arcuate slot 30 in housing H.
As will 'be evident, forward and rearward movement of link causes a corresponding'movement of drawer D, but the total movement of link 28 is less than the total movement of the drawer, and a lever 3| provides a considerably greater total movement of the drawer than of link 28. Link 28 is pivotally attached to lever 3| adjacent the lower end of the latter, which is pivoted on housing H, while lever 3| is provided with an inwardly offset upper end 32 adapted to clear housing H in movement into opening [8, as in Fig. 8. The upper end 32 of lever 3| carries a rod 33, provided at its opposite end with a roller 34 adapted to move upwardly and downwardly within a vertical yoke 35, preferably formed of channel or other flanged shape. Yoke 35 is welded or otherwise suitably attached at its lower end to bottom .22of
the drawer, and attached adjacent its upper end to a bracket 36, which in turn is attached at its forward end to front 2| of the drawer. Bracket 36 defines the space for reception of lower waste container l2, which is provided with a handle 31 for removal of the waste container from the drawer, as for emptying.
Due to the small amount of friction produced by rollers I9 and of drawer D, during movement of the drawer over the floor or other supporting surface, the force necessary to move the drawer to open position is relatively small, as is also the force necessary to return the drawer, so that spring 21 need not be unduly strong. The distance of traverse of the drawer D requires that the upper end of lever 3| move through a' relatively large arc, and link 28 is therefore pivoted on lever 3| much closer to the lower end of the latter than to the upper end thereof. The pressure on foot pedal 25, of course, not only moves the drawer out of the housing H, but also overcomes the force of spring 21, but again due to the small amount of friction required for movement of the drawer D, the force required to depress foot pedal is relatively small.
A further important feature of this invention is a floating sealing plate 40 for lower waste container I2, which automatically seals the container |2 when it is moved rearwardly into storage position, as in Fig. 3. Sealing plate 4|! rests upon the top of the container in storage position, and to insure the desired engagement of the plate. 40 with the top of waste container 12, plate 40 is pivotally supported from above, butin offset position. Thus, as in Fig. 4, the plate 40 will ordinarily be tipped rearwardly, so that when the drawer D is moved inwardly, the rear edge of the lower waste container |2 will first engage the plate 40 and tend to push it upwardly. As soon as the rear edge of the container passes the center of gravity of the plate during such movement, the plate 40 will tend to tip forwardly onto. the container, and the container slides underneath the plate, the plate'being supported by the container, so that an adequate seal is assured, as when the drawer and container reach the position of Fig. 3. The plate 40 is preferably relatively light so that very little friction (which would add to the force necessary to move the drawer) is produced by such sliding movement. When the drawer is pulled to open position, the container |2 slides out from underneath the plate 40, and the plate merely hangs in the position of Fig. 4 until the drawer is again closed.
Suitable means for supporting plate 4|] in a floating, ofiset position, may include brackets 4| attached to and extending upwardly from plate 4|] on each side thereof but slightly forwardly of the center of gravity thereof. Each bracket 4| is provided with a vertical slot 42 adapted to receive a pin 43, the latter being mounted on a supporting bracket 44 depending from partition |5. As will be evident, slots 42 not only permit pivotal movement of plate 40, but also vertical movement, thereby providing in effect, a lost motion connection. The length of slots 42 and position of pins 43 are readily made so the plate 40 floats, as it were.
The housing H is preferably made of relatively light metal, which construction is made stronger by partition: 15; Housing H may be further strengthened by a rolled. upper edge 45, which may be rolled about a reinforcing rod or wire. Similarly, the lower end of the housing may be provided with a rolled edge 46, which is preferably rolled around a rod 41, since due to the opening |8 for drawer D, there will normally be greater need for reinforcement at the lower end of the T housing than at the upper end. To permit the rollers 5|.
drawer D to be moved inwardly and outwardly a maximum distance, so as to provide a maximum dimension for waste container I2, in comparison with the floor space required by thehousing'H, the rear rollers 20 of the drawer D are preferably adapted to move as close to the outer periphery of reinforcing rod 41, the front rollers l9 are spaced inwardly with respect 'to the rear rollers 20, and rod 41 is provided with a rearwardly displaced, offset section 48. As will be evident from Fig. '7, offset section 48 accommodates the front rollers l9 when the drawer is moved to closed position.
In further accordance with this invention, the rear end of the drawer D is provided with side rollers 50, adapted to move along the interior of the side walls of the housing, to guide the drawer D toward and from open position. The rollers 50 also engage the rear, rounded corners M of housing H, to place the drawer D in more exact alignment, so that the drawer is substantially selfcentering as it moves back to closed position. Thus, there will be no tendency for the drawer to become twisted or misaligned, and only the minimum amount of pressure on foot pedal 25 will be required the next time the drawer is opened. Housing H, at each edge of opening l8, may also be provided with rollers 5| which are adapted to engage the sides of the drawer at the bottom, such as the sides of framework 23. The normal clearance between, the rollers 50 and 5| and the parts engaged thereby is preferably relatively liberal, not only to reduce construction costs, but also to provide an additional valuable feature of this invention, i. e., the locking of the drawer D when in open position, as shown'in Fig. 8. a
When the drawer D is moved outwardly to open position, as in Fig. 7, in the event that pressure on foot pedal 25 is released, .spring 21 win-1m mediately return the drawer to closed position. However, it often happens that the user will desire that the drawer shall remain-;open for a period of time, and this may be accomplished quite readily, merely by shifting or twisting the drawer to one side or the other; as by the foot, so that the front of the drawer will be shifted laterally, as to the position of Fig. 8. In this position, one of the rollers 5|! tends to wedge against the inside of the housing, and the drawer is wedged against roller 5| on the opposite side, or the drawer is wedged between housing side The drawer D can be'maintained in open position for'any desired len th .Q time,
merely by leaving it in the position of Fig. 8. When the drawer is to be closed, it is only necessary for the user to shift the drawer a short distance laterally in the opposite direction, as again with the foot, until the drawer is again in alignment, whereupon spring 2 1 will return the drawer to closed position.
The top lid is of the receptacle may be opened by hand, or by pressure on a foot pedal 54, disposed on the opposite side of the housing H from foot pedal 25, and preferably similar in construction to the latter. Lid foot pedal 54 may be pivoted at its lower end on a pin 55 mounted on housing H, as in Fig. 2, and provided at its upper end with a pin 56 extending through and movable in an arcuate slot 51 in thehousing. Pin 56 is pivotally attached at its inner end to the front arm of a double-arm lever 58, which is pivoted at its lower end on the housing H'by means of a pin 59, as in Fig. 7. The upper end of the rear arm of lever '58 is pivotally attached to the lower end of a rod 60 which extends upwardly through a slot 6! in partition I 5 and is pivotally attached at its upper end to a bracket '62, in turn attached to lid I6, as in Fig. 2. i r
In the position shown in Fig. 6, foot pedal 5% has been pressed to the floor, thereby moving the forward arm of lever 58 downwardly and pro ducing a corresponding rise in the rear arm of lever 58. This movement of lever 58 has, in turn, moved rod 60 upwardly, to raise lid ['6 to the position shown. The proportions of foot pedal 54 and lever 58 are preferably such that, in the position shown in Fig. 6, the upper end of the rear arm of lever 58 will have travelled slightly past dead center, so that the lid L6 will remain locked in open position. When thelid l 6 is open, access to upper waste container [3 is obtained, so that the desired waste may be placed therein, or the container may be removed for emptying, as by a handle 63, and'the container l3 later replaced in the upper compartment in. At the desired time, the lid l5 maybe closed by pushing the lid'upward slightly, thereby moving lever 58*back to dead center-i. e., wherein pin 59, the rear arm of lever 58, and rod 50 are in alignment. In such position, the weight of rod 60 will tend to swing lever 58 past dead center, and a'slight downward pressure on the lid will cause the lid to close,foot pedal 54 movin back to closed position, as in Fig. 3. It will be evident, of course, that other means for opening the lid 16 may be provided, and that, if desired, such means may be dispensed with altogether.
From the foregoing, it will be evident that the waste receptacle of thisv invention fulfills to a marked degree the requirements and objects hereinbefore set forth. For example, the combination of a housing and a drawer provided with rollers moving on the same surface supporting the housing, insures stability of the drawer, and
minimizes the necessity for weight of the housing. The force required to move the drawer inwardly and outwardly is relatively small, and also permits a spring of only nominal strength to be used for closing the drawer. This again reduces the force necessary to open the drawer, which ordinarily also must overcome the force of the return spring. A floating sealing plate for the waste receptacle disposed in the drawer insures a relatively tight seal with a minimum of interference with the movement and operation of the drawer or waste container disposed therein. Thepartition which divides the housing into upper and lower compartments not only provides support for theupper waste container, out also asupportfor the sealing plate, for the lower waste container. The incorporation of two waste containers in a single housing, with quick and easy: access to either or both-conserves floor space and also provides a more ready access to each container. The alignment and guiding rollers, mounted on the drawer and on the housing, contribute to the ease and'smoothness of operation, and the curved cor-1 ners on-the. rear of the housing cooperate with the guide rollers on the drawer to insure rearward alignment of'the drawer, in turn insuring a minimum of ,force necessary to reopen the drawer. Also, the mere shifting. of the drawer to lock it in position facilitates considerably the use of the receptacle. Additional ,valuable features have been pointed out herein.
7 It willbe understood, of course, thatvarious features of the present invention may be utilized without the remaining features. For instance, the drawer carrying the lower waste container may be an individual unit, installed in a cabinet or thelike. Also, other types of opening and clos-' ing devices for the drawer may be used, or the drawer, as well as the lid for the upper compartment, may be opened by hand. It will further be understood that various other changes maybe made, and that different embodiments of this invention may exist, all without departing from the spirit and scope thereof as defined in the appended claims.
