REFUSE CONTAINER AND DOLLY HAVING FOOT ACTIVATED RELEASE MECHANISM

Abstract: A container (10) and dolly (14) assembly is disclosed comprising a container having a planar rearward side (18) and a lid (12) that is pivotally coupled to one of the container handles (34) and pivots thereabout into a vertical orientation against the container (10). Retention flanges (45, 80) of the container (10) and the lid (12), respectively, overlap to lock the lid in the open position. A dolly (14) is provided having upwardly directed tine members (118, 122) that engage container flanges (58, 60) as the container is lowered upon the dolly to latch the container and dolly together. A pivotal foot pedal (38) is disclosed, operable to laterally move one dolly tine member (122) and thereby facilitate disengagement of both container flanges (58, 60) from the dolly tine members (118, 120).

Description: REFUSE CONTAINER AND DOLLY HAVING FOOT ACTIVATED RELEASE MECHANISM Background of the Invention Field of the Invention he subject invention relates generally to refuse container and dolly assemblies and, more specifically, to such assemblies providing for the attachment and release of a refuse container from the upper support surface of a wheeled mobile dolly. The Prior Art Conventional refuse containers typically are cylindrical and of plastic construction, and may be sold with or without a lid and with or without a wheeled carriage, or dolly. Most commonly, lids are completely detachable from the container. Typically, such lids are attached and detached by employing two diametrically opposed catches. While the aforementioned lid and container combinations work well, several deficiencies make their use less than satisfactory. First, normally two free hands are needed to engage or disengage the lid conveniently. This can prove cumbersome. Secondly, lids arc often lost, especially in commercial environments. This and the general inconvenience associated with their use often results in the separation of containers from their lids, even where necessitated by sanitary reasons or required by local law. I linged lids may be used to overcome these deficiencies, but the cost of available hinged lid assemblies is generally prohibitive. Moreover, conventional hinged lid assemblies are cumbersome in use and such non-removable lids, swinging uncontrollably, can impede efforts to conveniently and thoroughly clean the containers. Also, such lids, swinging freely and uncontrollably, can hinder a user in the dumping of the container contents . Similarly, conventional dollies are deficient in meeting the needs of the user in that they are attached and detached in a manner which is inconvenient. Moreover, such dollies arc unsanitary and are not particularly ergonomic in operation. Available refuse container dollies use variants of a "bayonet " or screw attachment design. Accordingly, the container is placed onto the dolly, or the container is inverted and the dolly placed thereon, and the mating bayonet flights or threads between the container and dolly are engaged. The dolly and container arc then rotated with respect to one another until the dolly and container have been draw n up snugly against one another. The inconvenience of the aforementioned assembly will be readily appreciated. In order to accomplish such a physical act, a user must place the container upright on the dolly, grasp the dolly between the user's feel, and tighten the container dow n. Often a user cannot be certain that the engagement has been successfully accomplished or sufficiently tight to avoid a disastrous unexpected separation of the dolly from the container. Alternatively, a user must bend down to hold the dolly w ith one hand w hile rotating the container with the other. This exposes the user to the accumulated dirt and other contaminants on the dolly and again, cannot be accomplished with absolute certainly that the engagement was successful. For those workers who have physical limitations, such a procedure can be impossible. Still, alternatively, the container can be positioned inverted upon the floor, secured between a user's feet, and the doily manually rotated to the bottom. Thisalso subjects the user to the accumulated dirt on the dolly, and to the uncertainly thai engagement has not been successfully achieved. In addition to the difficulties attendant the above assembly and disassembly operation, there are an additional number of disadvantages to (he present method of dolly attachment relative to the use of the assembly. A first drawback is the dolly'slendcncy to be rotated unintentionally as the assembly is pulled across thresholds thai impede the dolly's wheels. If such inadvertent rotation further tightens the dolly, it can be rendered difficult to remove. If such rotation loosens the dolly, it can disengage and cause serious injury if the user subsequently trips over the disattached dolly. In short, substantial safety issues result in conventional dolly assemblies where the user cannot ascertain whether the dolly is secured to the container. Summary of the Present Invention The present invention overcomes the aforementioned deficiencies by providing a dolly and container assembly having enhanced operator convenience and safet\ . The refuse container body is configured having a D-shaped cross-sectional configuration, with handles extending from radiussed sidewalls proximate to the planar rearward container side. Accordingly, a user can comfortably lift the container by the handles while positioned against the container planar side and thereby easily carry the container. The lid member is pivotally mounted to one of the handles and swings open to the side of the container. In the vertical, open orientation, the lid latches to the container side, thereby remaining stationary and out of the way of the user. A dolly is provided having an upper circular support surface for supporting the bottom of the container. The dolly further comprises upwardly projecting divergent tines, each having one end integrally formed with the dolly top surface and a free remote end extending above the dolly. The free ends of the tines are downwardh' beveled and engaged horizontal flanges in the underside of the container as the container is lowered upon the dolly support surface. Resultingly, the tine members laterally move inward until the container flange edges clear the tine remote ends. As the container moves downward, the line members resilicntly move laterally outward and resume their original orientation, and the remote tine ends latch over the container flange edges with an audible sound to secure the container and the dolly together. The dolly is further provided with a downward cavity at one end and a foot pedal member pivotally mounted within the cavity. The foot pedal comprises a forward actuator end that engages an outside surface of one of the line members and a rearward foot plate. Downward depression of the fool plate rotates the foot pedal and causes the actuator end to press the one line member inward, whereby releasing the container from its locking engagement with Ihe dolly. Thus, assembly of llie container to the dolly requires no user contact with the dolly and is positively assured by the audible latching of the tine members over the container flanges. Likewise disattachment of the container is positively assured by operation of the fool pedal to disengage the one locking tine. In addition, the lid. Pivoting and locking to one side of the container, does not interfere with movement of the dolly and container by the user or with attaching and detaching the container and dolly. Accordingly, it is an objective f the present invention lo provide a container and dolly assembly having a container lid that assembles to the container without hardware and tools, and locks into an open condition in a manner thai does not interfere with operation of the dolly or container. A further objective is to provide a container and dolly assembly having an improved mechanism for attaching the container to the dolly. Yet another objective is to provide a container and dolly assembly having a positive locking mechanism between the container and dolly. Still a further objective is to provide a container and dolly assembly having an improved crgonomic shape for enhanced convenience and utility. Another objective is to provide a container and dolly that can be attached and detached by the user without grasping the dolly or bending. A further objective is to provide a container and dolly attachment mechanism that provides tactile and audible feedback to the user of the attachment status. It is also an objective to provide a container and dolly having a foot actuated attachment/detachment mechanism. Yet another objective is to provide a container and dolly having a secure attachment mechanism that is easy and convenient to use. and that is not degraded through use. An additional objective is to provide a container and dolly that are economically and readily produced, readily assembled, and convenient in operation. These and other objectives, which will be apparent to those skilled in the art, are achieved by a preferred embodiment that is described in detail below and which is illustrated by the accompanying drawings.

Description of the Preferred Embodiment Referring first to Fig's. 1 , 2. and 10. the subject assembly comprises three primary plastic, injection molded components; a refuse container 10. a lid 12. and a dolly I 4. Suitable commercial grade polyethylene can be utilized in the formation of such components by conventional plastic molding techniques. The container 10 is generally cylindrical, comprising forward radiussed sidewalls 16. A rearward sidewall 18 of the container is substantially planar, having vertical edges which intersect the radiussed sidewalls 16. making the container generally D-shapcd in cross- section. The sidewalls 1 . 1 8 extend from a lowei container end 20 to an upper peripheral rim 22. Disposed on diametrically opposite sides of the radiussed sidewalls 1 . proximate the upper rim 22 and proximate opposite edges of the planar sidew all ai c outwardly projecting handles 24, 34. The handle 24 comprises spaced apart side- plates 26. 28. each having an inward end connected to the sidewalls 16. 1 8 and a I ] - shaped in section cross bar 30 connecting outward ends of the plates 26. 28. The cross bar 30 is of elongate configuration, radiussed across the bottom and forming a channel 32 along the top. Referring to Figs. 2. 9. and 10. the handle 34 likewise comprises spaced apart side plates 36, 38. and a U-shaped in section, elongate cross bar 40. Cross bar 40 includes a dependent U-shaped channel 42 extending between end walls 44. Fxtcnding downwardly into each end wall 44 from an upper edge is a pivot pin slot 46 having a circular, relatively large lower portion and a narrow pinch point 48 at the upper mouth. A vertically extending, outwardly projecting retention flange 45 is formed to extend along opposite side plates 36. 38 of the container handle 34. With reference to Figs. 4 and 10. the container 1 has a generally fiat bottom surface 50 and a pair of diametrically opposed hand recesses 52 which extend upward into the surface 50 at a location below the handles 24, 34. The bottom surface 50 comprises a further central recess 54 of elongate, generally elliptical shape, defined by a dependent peripheral skirt 56. I.xlending along linear ends of the recess 54 arc horizontal flanges or ledges 58, 60. The flanges 58. 60 are spaced apart and are projected in opposition as best shown by Figs. 4 and 10. f igures 2 and 9 illustrate the configuration of the lid 12. The lid component 12 comprises a domed top surface 62 that merges along a peripheral edge with a dependent skirl. The skirt includes radiussed forward portion 64 and a planar rearward portion 66 such that Ihe lid 12 is of a general D-shapc to compliment the shape of the container 1 . A pair of spaced apart arms 68. 70 extend outward from radiussed skirt portion 64, each arm 68. 70 having an inwardly directed surface 72. A hinge pin 74 projects inward from each arm 68. 70 and comprises a large diameiered circular head 76 and a smaller diameiered slcm 78. Extending along each surface 72 adjacent each hinge pin 74 is an elongate retention flange 80. Referring to Figures 2, 4, 5, and 7, the dolly 14 is constructed lo have a circular, generally planar top surface 82. Two diametrically opposite registration protrusions 84. 86 extend upward from surface 82. each complementarity shaped to the hand recesses 52 in the bottom of container 10. Four integrally molded spaced apart caster sockets 88 project outward from the dolly 14. each having a do nwardly opening axial bore adapted to receive the upwardly projecting post 92 of a caster 90. The dolly 14 has radiussed side walls 94 which extend peripherally rearward from a forward end of the dolly, and a planar vertical step crosses the dolly at a rearward end, marking the rearward boundary of surface 82. A foot pedal cavily 98. as best viewed from Figs. 2, 4. 6. and 7. extends dow nwardly into the top of the dolly at the rearward end to a bottom floor. The floor comprises a concave forward surface 100. a sharply inclined intermediate surface 1 2, and a ramped rearward surface 104. In front of the forward cavity surface 100 is a through opening 106 that extends through the dolly from a top side lo a bottom side. flic cavity 98 is defined by opposed sidewalls 1 12. 1 13 into each of which an inverted -shapc pivot post socket 108 extends, positioned along cavity 98 at the concave surface 100. A detent 1 10 extends into a top edge of sidewalls 1 12. 1 1 3 above each of the sockets 108. A central region 1 14 of the dolly 14 is molded to provide a planar bridging surface 1 16. as best shown in Figs. 2. 4. and 7. A forward!}' disposed, upwardly directed, tine member I 1 8 is joined to a forward end of the bridging surface by a reversely formed bight portion 120. and a rearwardly disposed, upwardly directed, tine member 122 is joined to a rearward end of the bridging surface 1 16 by a reversely formed bight portion 124. The tine 20 members 1 18. 122 are rectangular plates in con-figuration, projecting upward from the surface 1 16 at complimentary divergent angles; member 1 18 at approximately an obtuse angle of 100 degrees inclination and member 122 at an acute angle of 80 degrees of inclination. Moreover, the tine members represent cantilcvcred spring plates for latching purposes explained below. The forward tine member 1 18 has an upper formed over end portion 128 S that presents a downwardly angled upper beveled surface 130. The rearward tine member 122 has an upper formed over end portion 132 that presents a downwardly angled upper beveled surface 134. While the upper nd portions 128. 132 of the tine members are at equal elevation, the bight connective portion 120 of forward tine member 1 18 is shorter, as will be appreciated by Figs. 4 and 5. and the bight connective portion 124 of rearward tine member 122 is longer as shown. Consequently, tine member 1 18 is shorter than tine member 122 and has less resiliency and flex. Member 122 is, to the contrary, longer and is therefore more llexible in lateral directions toward and away from the bridging surface 1 16. Below the forward line member 1 18 is a through opening 1 6 that extends from a lop side of lhe dolly lo the bottom. The tine members 1 1 and 122 are integrally formed with the dolly body through the openings 136, 106 during the molding process. Accordingly, the dolly is an integrally molded unit thai requires no consumer assembly other than the casters and incorporates, through tine membeis I 18. 122. integral latching members of resilient and llexible plastic construction. The dolly further includes an actuating foot pedal 1 8. the pedal having a rearward!} disposed flat foot plate 140, five intermediately located separate and spaced apart pivot bearing portions 142 formed as integral, semi-circular dependent radiussed portions of three longitudinal flanges 143 and side portions of a dependent peripheral skirt 146 or, alternately, a single intermediately located pivot bearing portion may be formed extending the approximate width of the pedal 138. A forward actuating plate 144 extends forwar ly from Ihe pedal 138. The pedal 138 is integrally molded as one body. As shown in Figs. 4 and 6. the dependent peripheral skirt 146 extends about the periphery of the pedal 138 and spaced apart support flanges 148, 1 0 transversely span the underside of the foot plate 140. The bearing portion is formed as comprising the collective radiussed bottom surfaces 1 52 of the dependent flanges 143 and the radiussed lop surface 154. Fxlending outward from opposite ends of Ihe surface 1 54 arc wing extensions 1 56. 160 having a radiussed. downwardly concave shape. The forward end portion 160 of the pedal 138 is downwardly formed at an acute angle and represents the pedal portion which engages tine member 122 as described below. From Ihe foregoing and in reference to Figs. 1. 2, 3. 8, and 9. it w ill be appreciated thai the hinged lid 12 is operated by a one-hand procedure in a convenient manner. The lid 12 is fully and easily detached from the container 10 b} simple upwards disengagement of the lid hinge pins 74 from the container bearing slots 46 by passing Ihe pins 74 pasl the pinch points 48. lo substantial advantage. First, the upward disengagement motion is easy and fast, as ihe hinge pins are conveniently accessible. Secondly, the weight of the lid w ill always be positively supported by the container bearing slots 46 or container rim regardless of the position of the lid. The user of lhe container, by intended design and orientation of the handles, naturally will stand adjacent to the flat side 18 of the container to lifl and carry the container. The flat side 18 enables the user to carry the container closer to Ihe body. making for enhanced comfort and more efficient application of lifting force. Moreover, the orientation of lhe lid provides substantial advantage. The user can. by single handed operation, open the lid by lifting handle 162 and rotate into ihe vertical orientation shown in Fig. 8 without moving from the user's customary location against side 1 8. In the lid open condition, the user can move the container or insert matter into the container without moving. I he hinge pins 74 are of a head and stem configuration and are sized relali\ e lo Ihe slots 46. It will be appreciated that, in the configuration shown, it is not necessary to have a head on the end of the hinge pin stem 78. If one is used, its diameter must be greater than the stem diameter in order to be useful. If a head is not used on the hinge pin stem, then preferably Ihe slcm should be long enough lo sufficiently prevent the hinge pin from inadvertently dislodging from the slots 46. I he distance between Ihe pinch points 48 should be smaller than the diameter of lhe hinge pin stem 78 and large enough lo allow a "snap" removal of the hinge pin stem from Ihe slots 46. In short. Ihe sizing of lhe slots 46 and Ihe stems 78 of lhe hinge pins are complementary and interdependent. Additionally, the retaining labs or flanges 45. 80 on the lid arms 68. 70 as seen in Figs. 2. 9. and 1 1 must be sized relative to each oilier lo mutually engage in order to retain the lid in a fully open position and yet allow subsequent closure. Locking the lid open assists during loading and dumping of lhe container 10. Fig. 1 1 shows the ramped sides of the abutting flanges 45. 80 that facilitate the interference progression of the lid flange 80 over the container flange 45 as the lid assumes a lully open, vertical position. The ramped sides further facilitate subsequent reverse progression of lhe flange 80 over the flange 45 as the lid is closed. Assembly and operation of lhe dolly proceeds as follows. Referring lo Figs. 2. 4. and 6, the pedal 138 inserts downwardly into the cavity 98. whereupon wing extensions 1 56. 1 58 snap into the sockets 108. So seated, the radiussed underside 1 52 of the pedal portion 142 resides within the concave floor portion 100; pedal actuating plate 144 projects forward over the opening 106 and below line member 122: and pedal foot plate 140 is disposed above the ramped surface 104 of the cavil} 98. The wing extensions 156, 158 project into the sockets 108 to render the pedal pivotal within the cavity 98 between the depressed position shown in Fig. 4 and the released position of Fig. 5. Thus, extensions 1 56, 158 serve as pivot pins about which the pedal can pivot. Continuing, ihe position of lhe pedal in the quiescent, or released position of Fig. 5 is such that the surface 160 of the actuating plate 144 abuts against the outward surface of the line member 122. The angle of decline of surface 1 60 is complementary lo the angle of incline of tine member 122 so that the surfaces ihereol meet flush as shown. In the quiescent or released position, the foot plate 1 0 is raised above the cavity floor portion 104 and prevented from falling by the line member 122 keeping the actuating plate 144 end from rising. While the pedal 1 38 and the cavity 98 are configured pursuant to the above, other configurations for pivotally mounting the pedal 138 into one end of the dolly may be utilized if so desired. For example, a pivot rod securement of the pedal within the cavity can be used, although the subject preferred embodiment offers the advantage of a fastcncrless method of assembly with no tools required. To mount the container 10 upon the dolly 14, a user need only lift the container (preferably from a location adjacent the fiat side thereof) and, from a standing position, lower the container to its final destination upon surface 82. Guidance is provided by passage of registration protrusions 84. 86 into hand recesses 52. to facilitate engagement of lhe container 10 with tine members 1 18, 122. As the lower end of the container 10 reaches the line members 1 1 8. 122. inward ends of the container retention flanges 58. 60 engage the line surfaces 134. 1 0. respectively, and force ihe line members inward until ihe distance between tine ends 32 is sufficiently narrow to allow the container retention flanges 58, 60 to pass. As the flanges 58. 60 clear the tine ends 32. the tine members 1 18. 122 resilicntly snap outward and back into their respective quiescent orientations. The return of the tine members 1 18. 122 is accompanied by a positive audible sound and tactile feel as the underside of tine ends 32 latch over the top of the flanges 58. 60. Accordingly, a user will positively know that a secure lock has been achieved. When container and dolly are fully engaged, the registration protrusions 84 and 86 securelv engaged within container hand recesses 52 serve as holding blocks to lake lateral and rotational stress off ihe tine members 1 18 anil 122. The combined cooperative effect of the protrusions 84. 86 and the latching tine members 1 1 . 122 result in a secure, rotationlcss interface between the container bottom and the dolly. In the assembled condition of Fig. 1 , the container and dolly can be manipulated by the user from adjacent the flat container side. The dolly fits beneath the container such that the curvilinear side of the container can be maneuvered into a corner for storage Alternatively, the flat side of the conlainer can be stored against a w all if so desired to conserve space As shown, it will be appreciated that the foot plate 140 is always accessible to the user from a position adjacent the flat conlainer side, since plate 140 projects rearward and beyond the flat container side 18. To release ihe container from the dolly, the foot plate 140 is pressured downward as shown in Fig. 4. bottoming out against the surface 104. Pivolal movement of the plate downward moves actuation plale 144 upward and end portion 160 presses tine member 122 inward until tine end 132 clears container flange 58. Thereupon, the conlainer can be moved laterally and/or upwardly until the opposite tine member end 128 clears flange 60. enabling the conlainer to be lilted up and clear of the dolly. Inward movement of tine member 122 is rendered easier by the relative height of the member which makes the cantilcvercd tine more flexible and easier to move. Conversely, the relatively low height of tine member 1 1 8 makes it cly stiff; which contributes to enhancing Ihe integrity of lhe resulting lock. From the foregoing, it will be appreciated that a user need nol touch the dolly. bend, or invert the container in order to accomplish attachment of lhe conlainer lo the dolly. Such can be achieved by simple downward movement of the container to the dolly top surface Similarly, disattachment of the container docs not require ihe user to grasp ihe dolly, bend, or invert the conlainer buy hand. By rendering the attachment and disattachment of the dolly so convenient to the user, the subject invention facilitates more frequent emptying of the container by the user at shorter intervals, and thereby the container is less full. Stale of the art dolly and conlainer assemblies are so cumbersome to separate that a user is more inclined to resist emptying the container until it is entirely full or emptying the container with the dolly still attached. Likewise, the subject invention provides a latch that cannot be compromised or altered by use of the combined container and dolly. Unlike screw or bayonet threaded dolly attachments, the encountering of curbs or thresholds by the wheels of the subject dolly will not alter the security of the attachment lo render disengagement o lhe dolly more di fficult since the attachment of the present invention is not achieved by rotary movement. Thus, the user need not be concerned that the attachment has loosened into an unsafe condition through use or tightened beyond the user's capacity to free it. Lastly, it will be noted that the subject invention, comprising four molded parts is economical to manufacture and. because no assembly hardware is required, the cost of lhe assembly is further minimized. In addition, there are no parts that will require frequent replacement from repeated use Thus. Ihe assembly is durable and economical and represents a substantial improvement over more cosily and less durable conventional container and dolly assemblies. It will be noted that the subject invention comprises a dolly and container that assemble by linear movement between the container and ihe dolly, preferably but not necessarily linear movement of the container toward Ihe stationary dolly. Thus, rotation of the dolly or container is not necessary and a touching of lhe dolly to initiate such rotation is not necessary. Rather, the container is simply lowered downward and establishes latching engagement without contact between the user and the dolly. Moreover, the dolly and the container have interfitting protrusions and recesses, respectively, that interfit to register the container upon the doll}' support surface and further to prevent any rotational movement Iherebelwecn. In the preferred embodiment, the recesses of the container into which the protrusions of lhe dolly fit are hand recesses in the container bottom. The hand recesses are located below the container handles and serve to receive Ihe user's hand and facilitate a lifting of lhe container by the bottom when the container is separated from the doll} . Thus, each of lhe container recesses serve two functions: one as a hand recess for lifting ihe container and secondarily as a registration recess. It is also apparent that the latching tines engage the lower portion of the container and as they snap over the container flanges, emit an audible "click" to communicate to the user thai a successful attachment has been achieved, ' fhe audible sound thus acts to reassure the user and the absence of the sound indicates a lack of success. And. since the only direction by which the container can become disallached is vertically (i.e.. lifting the container after its release), it is not likely to become inadvertently unattached from the dolly during use Finally, it will be appreciated that the pedal member is foot actuated which makes it possible to disassemble the container from the dolly without the user touching the dolly. For sanitary reasons, this is important. Preferably, the foot actuated pedal is pivotally attached to the dolly but other modes of operation will be apparent. l or example, without any limitation intended, a slide mechanism can be devised lhal. subject lo foot pressure, moves linearly to press Ihe tine 122 out of engagement with the container. It will be readily apparent that Ihe container travels in a linear vertical direction relative to the dolly during the attachment procedure: i.e. il is lowered lo the dolly by the handles by an creel user. The reverse linear direction is necessary for separation. Il is the linear, non-rotary nature of the separation and attachment movements that makes Ihe assembly resistant to the inadvertent separation attendant rotationally attached containers and dollies. While preferably in the vertical linear direction, the subject invention contemplates that a horizontal linear attachment of lhe container to the dolly may also be constructed pursuant to the teachings herein. By horizontally orienting the dolly tines and providing a vertical flange in the bottom of the container, the container can slide horizontally across the top surface of lhe doll} until the lines snap over the vertical container flange ' fhe foot pedal can be configured lo depress one or both o lhe tines to free the container from the doll}'. While not as convenient to assemble as the preferred embodiment which contemplates rclali \ e movement in the vertical direction, the horizontal linear allachmcnt of the container to the dolly would provide some of lhe advantages, such as resistance to inadvertent separation, over ihe rotationaliy attached state of the art assemblies. While the above describes the preferred embodiment of lhe subject invention, the invention is not intended to be so restricted. Olher embodiments, which w ill be apparent to those skilled in the art, and which utilize the teachings herein set forth. are intended to be within the scope and spirit of lhe subject invention. By way of example, without an intention to limit, the number and location of lhe dolly tine members may be varied. In addition, the dolly need not necessarily be used in conjunction with containers having the subject flat side, but may be used on conventional cylindrical containers. Other variations, obvious to those skilled in the art, will also be readily apparent.
