The present invention relates generally to a refuse collection vehicle and, more particularly, to a refuse collection vehicle having a stock body which enables a dealer or other user to customize the rear end portion of the refuse collection vehicle with a rear loader attachment for lifting and dumping various types of commercial containers. The present design allows a dealer or other user to customize the vehicle after the fact more easily for local market needs.
Various types of refuse collection vehicles are well known in the industry. These vehicles include, among other things, a storage compartment and a mechanism for emptying the refuse material collected within the storage compartment. Some of these vehicles include a receiving hopper typically located forward of the storage compartment, the receiving hopper being designed to receive the refuse material when loaded within the vehicle body. Depending upon the local market needs, many of these vehicles are customized so as to receive and dump commercial containers or dumpsters located at various business sites. Typically, the rear loader attachment for capturing and dumping commercial containers is welded to the rear portion of the refuse collection vehicle thereby restricting that particular vehicle to a particular rear loader attachment and further restricting that vehicle to receiving and dumping only commercial containers.
It is therefore desirable to have a bolt-on rear loader attachment for receiving and dumping commercial containers which is not permanently attached to the rear end portion of a refuse collection vehicle and which can be easily attached to and detached from a stock rear end portion of a refuse collection vehicle so that the dealer or other user can easily change the performance of the vehicle to meet the needs of their changing route dynamics.
The present invention therefore seeks to overcome the shortcomings and disadvantages associated with permanently attaching rear loader attachments to a refuse collection vehicle by providing a bolt-on rear loader attachment as well as a bolt-on winch assembly which are typically used for receiving and dumping commercial containers.
According to one aspect of the present invention, there is provide a refuse collection vehicle having a standard stock rear end body which will allow for a rear loader attachment to be removably attached to the standard stock rear end vehicle body so that the vehicle can be transformed into receiving and dumping commercial containers. The present bolt-on rear loader attachment includes a curb side latch assembly and a street side latch assembly which can be easily bolted to a standard stock rear end portion of a refuse collection vehicle. The present design likewise includes a hopper extension member which can likewise be easily attached to and removed from the rear end portion of the refuse collection vehicle and further includes a bolt-on roll bar assembly for facilitating the lifting and dumping of a commercial container. These assemblies can be easily attached to and removed from a standard stock rear end portion of a refuse collection vehicle.
In addition, in some instances, a winch mechanism may likewise be utilized to dump certain types of commercial containers. The present invention further includes a bolt-on winch assembly which attaches to the upper portion of a standard stock refuse collection body, the bolt-on winch assembly including a winch mounting cross frame member, a winch mounting frame member, and a winch attached to the winch mounting frame member for attaching to the upper end portion of a standard stock vehicle body.
Additional features of the present invention will be described in the course of the following detailed description.
For a better understanding of the present invention, reference may be made to the following accompanying drawings.
While the present disclosure is susceptible to various modifications and alternative forms, a specific embodiment of the present invention is shown by way of example in the present drawings and will herein be described in detail. It should be understood, however, that the present drawings and detailed description presented herein are not intended to limit the disclosure to the particular embodiment disclosed, but to the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure as defined by the appended claims.
Referring to the drawings more particularly by reference numbers wherein like numerals refer to like parts, the number 10 in
The present invention includes a curb side latch assembly 22 and a street side latch assembly 24 which likewise includes a plurality of corresponding openings or apertures 26 which enable the curb side and street side latch assemblies to be bolted directly to the flange members 12 and 14. The latch assemblies 22 and 24 are bolted to members 12 and 14 through a plurality of latch bolts 28. The latch assemblies 22 and 24 each include a rotating arm member 30 which can be manually manipulated by the vehicle driver to capture a corresponding roll bar (not shown) associated with a typical commercial container. The rotating arm members 30 each likewise include a plurality of scoops or cutouts 32 for receiving the roll bar associated with a typical commercial container. Each arm member 30 is movable between an open position as illustrated in
Depending upon the type of commercial containers being captured and dumped by the refuse collection vehicle, a wide variety of different types of hopper extension members 36 can likewise be attached to the rear end portion of the refuse vehicle 10. As illustrated in
Once the curb side latch assembly 22 and the street side latch assembly 24 are removably attached to flanges 12 and 14, and once the hopper extension member 36 is attached to cross member 16, the bolt-on roll bar assembly 40 can be attached directly to the latch assemblies 22 and 24 as illustrated in
In one aspect of capturing and dumping a particular style of commercial container, the vehicle operator will rotate and open the respective latch arm members 30 associated with each latch assembly 22 and 24 as best illustrated in
In another aspect of the present invention, some commercial containers require the use of a winch mechanism in order to lift and rotate the commercial container into a position for dumping any refuse material contained therein into the storage compartment 18 of a typical refuse collection vehicle. The present invention also includes a removably attachable winch mechanism 52 which again can be removably attached to a standard stock refuse collection vehicle body without the need for permanently attaching the winch mechanism to the vehicle. This again gives a dealer and/or user more flexibility in customizing the rear end portion of the refuse collection vehicle depending upon the type of commercial containers to be captured and dumped and depending upon local market needs.
As best illustrated in
In operation, the hook portion 66 of the winch 60 is attached to one side portion of a typical commercial container and the roll bar associated with its opposite end portion is attached to the latch assemblies 22 and 24 in a conventional manner as previously explained. The winch 60 is then utilized to rotate the commercial container about its roll bar captured within the latch assemblies 22 and 24, and the roll bar frame assembly 40 is then rotated such that roll bar 46 engages the back side of the commercial container and facilitates the dumping of the refuse material from the commercial container into the storage compartment of the vehicle. Here again, this dumping operation is done is a conventional manner using the winch mechanism 52.
Use of the present removably attachable rear loader attachment and the removably attachable winch mechanism enables dealers and daily users of refuse collection vehicles to customize their vehicles depending upon the particular type of commercial container needed to be collected and dumped as well as depending upon local market needs and changing route dynamics such that the same refuse collection vehicle can be used and adapted to a wide variety of different dumping applications. This greatly improves the flexibility of the dealer, user and the particular refuse collection vehicle and eliminates the need for having a particular type of rear loader attachment mechanism permanently mounted and/or welded to the refuse collection vehicle. Obviously, a permanently mounted attachment limits the use of that particular vehicle to one particular type of a dumping operation. The present invention allows a dealer and user to remove the present bolt-on rear loader attachments as well as the winch mechanism so that the refuse collection vehicle can be used for other applications.
It is also recognized and anticipated that the overall shape and dimensions of the various components associated with the present rear loader attachment including the curb side and street side latch assemblies 22 and 24, the rear hopper extension member 36, and the roll bar assembly 40 are all subject to wide variations and may be sized and shaped into a wide variety of different sizes and configurations so as to be compatible with and attachable to the rear end portion of a standard stock refuse collection vehicle body. The same is likewise true with the various components associated with the winch mechanism 52. In addition, other attachment means other than bolts may likewise be used to attach the various components of the present invention to the rear end portion of a standard stock vehicle body so long as the attachment means are removable such that the present rear loader attachment mechanism and the present winch mechanism can be attached to and easily removed from the vehicle body. In addition, the various components of the present invention can be sized and shaped so as to conform with various space limitations associated with a particular standard stock vehicle body without impairing the teachings and practice of the present invention. Other variations and modifications to the various components comprising the present invention are likewise envisioned and contemplated.
Thus, there has been shown and described a removably attachable rear loader attachment mechanism as well as a removably attachable winch mechanism for use on a standard stock refuse collection vehicle body. As is evident from the foregoing description, certain aspects of the present invention are not limited by the particular details of the examples illustrated herein, and it is therefore contemplated that other modifications and applications, or equivalents thereof, will occur to those skilled in the art. The terms “having” and “including” and similar terms as used in the foregoing specification are used in the sense of “optional” or “may include” and not “as required”.
