       BACKGROUND  
         [0002]    1. Field of Invention  
           [0003]    This invention relates to tiltable wheeled containers used for refuse and recycling storage, hitching and movement.  
           [0004]    2. Description of Prior Art  
           [0005]    Recycling bins have been used to store and move materials for over 40 years. The methods used are different for commercial and residential. Recycling was introduced long after refuse collection had be in place and has been treated as an independent operation. At first recyclable materials were piled separately, then bundled, then placed in a container, then more sophisticated containers were developed having multiple or divided containment areas. The problem with multiple bin units was that the contents had to be emptied into different larger containers making this a difficult task that required lifting all the contents and blocking the contents that were not to be dumped into the larger container . Residential recycle bin designs have been constrained by cost and lifting weight. The higher demand for separation of different recyclables has resulted in the need for two or more bins. Simple bins have been made stackable to reduce space and carts have been made to move the bins to the curb.  
           [0006]    Recycle bins are presently a simple rectangular box with an edge for lifting and drain holes in the bottom since there is no cover from rain or snow. The size is determined by the lifting weight for the worst case scenario of wet newspaper. This bin requires bending to lift and must be held away from legs due to filth on the bin or rainwater that drips out of tilted cans and jars. This is very difficult especially for seniors or people with back problems. Recycle bins with wheels have not been commercially successful due to the maximum lifting weight does not allow the height of the container to reach an ergonomically suitable height to wheel the container. If the maximum size container was stretched to that height of about 34 inches free standing, then the base would be too small to be stable. The conventional 32 gallon wheeled refuse containers are already disliked by the collection workers for their instability and their narrow wheel base of the cylindrical shaped containers makes them difficult to roll. This has lead to square based containers to increase the wheel base and to prevent rolling in the wind when empty, even though the cylindrical shape provides greater structural integrity and simplicity of manufacture. The larger 60 gallon containers will not be emptied by the collection workers due to their excessive weight. Refuse and recycle containers that have dividers vertically such as in U.S. Pat. No. 4,834,253 to Crine are to difficult to dump because the entire weight must be lifted while only one portion is dumped and the remainder portions blocked.  
           [0007]    The recycling cart of U.S. Pat. No. 5,192,092 to DIBENEDETTO (1991) is an expensive item by itself that would have to be unloaded and taken away from the curb or risk theft. The cart would then be brought back to the curb to pick up the empty bins. The cart still requires bins of which the owner may already have. The owner&#39;s bins may not fit the cart since recycle bins vary in dimension thus making universal cart manufacture difficult. The bins must also be secured and unsecured to the cart for rolling. The cart and bin of U.S. Pat. No. 4,821,903 to Hayes (1988) has the same problems of expense and theft but bins do not require securing. The bins are however custom made and are expensive to make and unsuitable for newspaper that would require “sliding in” instead of being “tossed on a pile”.  
           [0008]    The stackable refuse system of U.S. Pat. No. 5,445,397 to EVANS (1994) offers a more economically viable solution for a multiple bin unit. It also has the advantage of nesting which allows for efficient distribution. It also has the advantage of forming a rigid entity from several bins by means of a flexible strap with a clasp, thus providing the required ergonomic height for tilt and rolling and reducing the effective lifting weight upon detachment. However the method of securing to form a rigid entity is not a system that secures individual bins to each other (adjoining bins) but rather a strap that compresses a number of bins and wheel assembly to form a single rigid entity that can be tilted. The wheels must be added by a separate wheel assembly because there is no individual means of securing wheels to of bottom bin or added by the alternate embodiment, of a cart, to overcome this problem. The wheels are not integral with the bottom bin resulting in additional user labor. The preferred embodiment has lids because if stacked without them it would result in the unit sloping over the wheels. The alternative embodiment uses an expensive metal tubing cart which would require the lids as well to avoid the sloping problem but then allows for the elimination of the flexible strap and having to bend over to pick it up. This design cannot be blow moulded. The wheel base of the preferred embodiment will not nest within itself thus adding to the distribution cost, and the metal frame cart is even more cumbersome to ship. The lids add expense and require the additional labor of securing or removal upon dumping and then re-assembly.  
           [0009]    Wheeled objects that are tilted for rolling have never been secured together from their free standing position to form a single entity wheeled cart whether hitched or castor wheeled. Two wheel tilt and roll containers or any similar tilt and roll device, such as a luggage container, has never been hitched at the top end nor has there been a way to tilt the devices after being hitched. Trains of containers have be made for commercial application using hitched or linked dollies. These systems have the following disadvantages: requires independent dolly, the dolly has 4 wheels for stability, some or all of the wheels must have the ability to swivel to allow the train to go around corners, the castor wheels are small to keep reduce cost as well as reduce over all height to minimize vertical instability. The small wheels and instability limited the terrain to smooth indoor surfaces due to the inability for small wheels and swivel castors to roll over large bumps. The operator must be in a bent over position including the work and hardware to connect the containers to dollies. This work must the be undone and redone if there are any steps or stairs because the container dolly units cannot move independently in the vertical direction and the upper lateral movement is aggravated due to the height of the container since they are free to move independently at the top. Unless all 4 of the castors on the dollies are swivel type, the direction of train movement cannot be reversed and containers must be locked to the dollies thus limiting versatility.  
         SUMMARY  
         [0010]    In accordance with the present invention a tiltable modular recycle container system comprising a new use for handles to form a rigid entity from independent adjoining containers, and a means to bring combinations of refuse and recycle containers to the curb in a single trip by hitching them at the top for transport in a tited position.  
         OBJECTS AND ADVANTAGES  
         [0011]    Accordingly, besides the objects and advantages of the tiltable modular recycle container system described in my above patent, several objects and advantages of the present invention are:  
           [0012]    (a) to provide a means to bring the refuse containers with the recycle bins to, as well as from the curb in a single trip.  
           [0013]    (b) to provide a low cost multiple bin container that has a large overall weight capacity but can be tilted and rolled to the curb and then easily detached to reduce the effective lifting weight and direct sorted contents to separate destinations.  
           [0014]    (c) to provide a recycle container that is secured to, or rests on, future or presently existing wheeled refuse containers in order to eliminate one of two trips as well as having to carry the recycle container in situations where only one recycle container is required.  
           [0015]    (d) provide improved resting and rolling stability due to the larger bottom and wider wheel base by overcoming the codependent lifting weight/ergonomic rolling height constraint that determines the bottom size and wheel base width by means of dividing the container to reduce the effective lifting weight.  
           [0016]    (e) to provide a new use for handles, which are presently used to lock the lid on refuse containers, for use in securing recycle bins on new and existing refuse containers, securing independent refuse and/or recycle bins into a rigid entity that can be tilted and rolled, and as well as part of a hitch that allows the containers to be tilted from the rest position while remaining hitched.  
           [0017]    (f) to eliminate the need and expense of an independent cart for holding and moving recycle bins by securing independent recycle containers together to form a single rigid container that fulfills the function of the cart which can be tilted and rolled.  
           [0018]    (g) wheeled objects that are tilted for rolling, secured together from their free standing position, to form a single entity wheeled cart using hitch or castor wheels for turning means, eliminates wheels and allows one to increase the capacity but still reduce effective lifting weight by unsecuring.  
           [0019]    (h) to reduce the number of parts such as lids, flexible straps with clasps, independent dollies with small wheels and casters, carts and the means for securing all of the mentioned parts.  
           [0020]    (i) to reduce and simplify operations and the number of operations for securing and unsecuring parts such as lids, flexible straps with clasps, independent dollies with small wheels and casters, and carts.  
           [0021]    (j) to provide a system that can be added to existing refuse containers and modified to meet changing weekly needs such as alternating type of recycle pick up, and long term changing capacity needs.  
           [0022]    (k) the wheeled containers will nest in each other and the recycle containers will nest in each other and the wheeled containers will also nest in the recycle containers and the lower size of recycle containers can partially nest in the upper size of recycle container, thus being able to form a single pile of any number of sizes of recycle containers with the wheeled containers reducing shipping costs and distributor shelf space even for small quantities.  
           [0023]    (l) provide the ability to deposit recyclable materials without having to remove lid, lift door, or dismantle while still providing covering from rain and snow.  
           [0024]    (m) provide low cost, easy to engage handles, that have a positive lock and are not subject to orientation of container placed on top of them, and have an ergonomic advantage of for lifting as well as all the advantages listed in the U.S. Pat. No. 4,691,840 FERBRACHE patent.  
           [0025]    (n) provide a container system that could also function as a yard cart or general use cart.  
           [0026]    (o) to provide a design of recycle bin that can be blow moulded.  
           [0027]    Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.

     DESCRIPTION  
       [0040]    [0040]FIG. 1—Preferred Embodiment  
         [0041]    A preferred embodiment of the present invention of the tiltable modular recycle container system is illustrated hitched to an existing 32 gallon Rubbermaid refuse container with a single recycle bin secured on top of it. This system allows for a single trip to the curb regardless of how many recycle bins or refuse containers are required without any carrying. The wheeled recycle bin  1  is preferably blow moulded or may be injection moulded, from the appropriate plastic for the type of manufacturing process used. The wheels  8  are located on the pulling side providing stability in the vertical rest position and a means for rolling near the center of gravity while tilted or moving. Refuse container lid  9  rests on the refuse container recycle bin  3 . The flanged opening  7  has the flange protruding outward and allows items to be place in without having to lift the upper recycle bin  2 . For indoor storage the upper recycle bin  2  would have no opening in order to control odors. The handles  4  are used to secure the wheeled recycle bin  1  to the upper recycle bin  2 , upper recycle bin  2  to the upper recycle bin lid  5 , and the refuse container  10  to the refuse container recycle bin  3 . The handle  4  of the refuse container  10  is in the unsecured position and is hitched to the handle of the upper recycle bin  2  by the hitch  6 .  
         [0042]    [0042]FIG. 2 
         [0043]    [0043]FIG. 2 shows the cross section of the preferred embodiment of the interface of the wheeled recycle bin  1  and the upper recycle bin  2  secured by the handle  4 . Details of the handle can be found in U.S. Pat. No. 4,691,840 FERBRACHE patent. The upper recycle bin  2  resting position is determined horizontally by alignment edge  15  and vertically by support face  14 . The tooth projections  16  prevent the upper recycle bin from separating from the wheeled recycle bin by extending into indent  11  and restricting the movement, in the vertical direction, of base of indent  12 . The grip  21  of the handle  4  allows lifting and releasing by rotating about stud projection  18  which pivots in mounting boss  20  to overcome resistance fit between lobe projections  17  and receptacle base recesses  19 .

         [0045]    [0045]FIG. 2A shows the cross section of the preferred embodiment of the interface of the upper recycle bin  2  and the upper recycle bin lid  5  secured by the handle  4 . Details of the handle can be found in U.S. Pat. No. 4,691,840 FERBRACHE patent. The upper recycle bin  2  resting position is determined horizontally by alignment edge  15  and vertically by support face  14 . The tooth projections  16  prevent the upper recycle bin lid  5  from separating from the wheeled recycle bin by extending into lid indent  11 A and restricting the movement, in the vertical direction, of lid base of indent  12 A. The grip  21  of the handle  4  allows lifting and releasing by rotating about stud projection  18  which pivots in mounting boss  20  to overcome resistance fit between lobe projections  17  and receptacle base recesses  19 .  
         [0046]    [0046]FIG. 3 
         [0047]    [0047]FIG. 3 shows the cross section of an existing 32 gallon Rubbermaid refuse container  10  with the preferred embodiment a refuse container recycle bin  3  on top of it to be used when a single recycle bin is to be transported to the road without carrying it. The refuse container recycle bin  3  is secured by the handle  4 . Details of the handle can be found in U.S. Pat. No. 4,691,840 FERBRACHE patent. The refuse container recycle bin  3  resting position is determined horizontally by indent flange  24  and vertically by indent resting face  25  and resting shoulder  26 . The tooth projections  16  prevent the refuse container recycle bin  3  from separating from the refuse container  10  by extending into indent flange  24  and restricting movement in the vertical direction of indent locking face  23 . The grip  21  of the handle  4  allows lifting and releasing by rotating about stud projection  18  which pivots in mounting boss  20  to overcome resistance fit between lobe projections  17  and receptacle base recesses  19 .  
         [0048]    [0048]FIG. 4 
         [0049]    [0049]FIG. 4 shows the preferred embodiment of the hitch  6  that would be used when connecting handles  4  of existing refuse containers  10  to each other or to upper recycle bin  2  that are secured to wheeled recycle bin  1  or any combination there of The hitch  6  consists of two identical clasps  37  that can rotate relative to each other about rivet with washer  31  in the plane of the pivot face  34 . The rivet with washer  31  hold the clasps  37  together through the countersink holes  36  which allow grip  21  of handle  4  to rotate freely in the clasp groove  33 . The grip  21  is secured in the clasp groove  33  between the inner clasp projection  35  and the outer clasp projection  38  by the spring action of flexible groove body  39 . The release grip  32  allows pressure to be applied for unhitching of each clasp  37 .

       ADVANTAGES  
       [0117]    From the description above, a number of advantages of my tilted modular recycle container system become evident:  
         [0118]    a) securing individual containers directly to each other to form a single rigid entity, rather than a strap that compresses a number of bins and wheel assembly together, is much simpler to use.  
         [0119]    b) a low cost simple, versatile system for home and commercial use  
         [0120]    c) easily adapted to owner&#39;s existing refuse container and future changing needs  
         [0121]    d) hitch is easily secured to the handles  
         [0122]    e) hitch(s) can remain secured during; the trip from the curb, park and loading, and back to the curb, without having to be unsecured  
         [0123]    f) the refuse container recycle bin allows for situations when only one recycle bin is required or alternating collection is practiced  
         [0124]    g) the rivet with washer  31  of the hitch allows for turns greater than  90  degrees  
         [0125]    h) the design of the clasp  37  transfers the load through the hitch while minimizing the force required for securing and unsecuring handles.  
         [0126]    i) the multiple hitched containers can be tilted one at a time and left free standing tilted while be filled and parked  
         [0127]    j) recycle bins can be blow moulded allowing for superior performance, lower cost plastics with lower tooling cost, and will also nest in each other.  
         [0128]    k) the new use for a proven reliable, and practical handle wins the confidence of the consumer.  
         [0129]    l) the improved stability due to the wider wheel base that can be obtained by forming a single rigid entity from smaller units.  
         [0130]    m) light weight contents are secured from blowing away and kept dry by coverings.  
       OPERATION FIG.  1 - 11   
       [0131]    The manner of operation of a handle  4  for securing containers on top of each other is similar to the present use for securing lids  9  to the Rubbermaid 32 gallon refuse container  10  and is described in detail in the Ferbrache U.S. Pat. No. 4,691,840 patent. In the secured position, the handle  4  is rotated about stud projection  18  in an upward and inward direction towards the center vertical axis of the wheeled recycle bin  1  until the tooth projection  16  is touching the indent  11 . In the unsecured position the handle  4  is rotated about stud projection  18  in an outward and downward direction towards the center vertical axis of the wheeled recycle bin  1  until the handle rests on the container wall, or hangs freely.  
         [0132]    The placement of the upper recycle bin  2  on the wheeled recycle bin  1  is different from refuse container lid  9  placement in that it may also be forced down while handles  4  are in the secured position. The sides of the upper recycle bin  2  must also be aligned with the sides of the wheeled recycle bin  1  and the grips  21  of handles must be parallel to the axis of the wheels  8  when hitching. The upper recycle bin  2  is lowered so that it&#39;s lower portion nests inside the alignment edge  15  of the wheeled recycle bin  1  and the rest face  13  rests on the support face  14 . The handles  4  that were initially in the secured position will have been displaced outwardly and then sprung back to the secured position by the elastic force of the stressed receptacle base recesses  19  on the lobe projections  17 . Handles  4  that were initially in the unsecured position may now be moved to the secured position prior to tilting to form the rigid entity.  
         [0133]    The placement of the upper recycle bin lid  5  on the upper recycle bin  2  is different from cylindrical refuse container lid  9  placement in that it the sides of the upper recycle bin lid  5  must also be aligned with the sides of the upper recycle bin  2 . The upper recycle bin lid  5  is lowered so that it&#39;s lower portion nests inside the alignment edge  15  of the upper recycle bin  2  and the lid rest face  13 A rests on the support face  14 . Handles  4  that were initially in the unsecured position may now be moved to the secured position.  
         [0134]    The placement of the refuse container recycle bin  3  on the refuse container  10  is the same as refuse container lid  9  placement. Handles  4  that were initially in the unsecured position may now be moved to the secured position prior to tilting.  
         [0135]    The hitching of refuse containers  10  and tiltable modular recycle containers, and multiple combinations there of, requires the same operation. The containers are easier to hitch when in the free standing vertical rest position but may also be hitched while one or both are tilted and when handles  4  are secured or not secured. The hitch  6  is placed preferably on the lower radius of the grip  21  so that the axial center of one of the clasps  37  is aligned with the axial center of the grip  21  and the outer clasp projection  38  and the inner clasp projection  35  rest on radius of the grip  21 . The other clasp  37  is preferably located furthest from tooth projections  16 . The clasp  37  and grip  21  are squeezed together, between fingers and palm, causing the flexible groove body  39  to straighten, increasing the distance between the inner clasp projection  35  and the outer clasp projection  38 , until they pass the maximum outer diameter of the grip  21  after which clasp groove  39  will seat itself along the grip  21  as flexible groove body  39  returns to it natural unstressed shape. The clasp  37  is now free to rotate about the grip  21 . The other unsecured clasp is similarly secured on the grip  21  of the container to be hitched. The unhitching of containers requires a force applied, preferably with the thumb, to release grip  32  in a direction tangential to the circumference of the grip  21  while supporting the handle  4  with fingers of hand or other hand.  
         [0136]    The tilting of independent containers is preferably achieved by placing one&#39;s foot in front of the base of the wheeled side of the container and pulling the container lid toward one&#39;s body with one hand holding the grip  21  of the handle  4  with the other hand. Hitched containers are tilted the same manner but preferably the rear container  10 R is first tilted by placing one&#39;s foot in front of the wheeled side of it and pushing with foot while unsecuring handle  4  of the center container  10 C adjacent to the wheels  8 , and rolling the rear container  10 R away from the center container  10 C until the unsecured handle  4  is at handle tilted rest point  64 . The center container  10 C is tilted second, after tilting rear container  10 R, in the same manner, and then the lead container  10 L is tilted.  
       CONCLUSIONS, RAMIFICATIONS AND SCOPE  
       [0137]    Accordingly, the reader will see that the tiltable modular recycle bin system of this invention fulfills a long felt need for a low cost container system to bring refuse and a number of recyclables to the curb in a single trip without carrying. The invention of forming a single rigid entity from adjoining independent units allows tilted transport while overcoming the lifting constraints and eliminating the cart. This coincides with new use for the Ferbrache style of handles as a means for securing containers to form a single rigid entity, single recycle bins on the top of refuse containers, and hitching tiltable containers at the top. This would also include such things as tiltable luggage or suit cases that are wheeled and general purpose utility carts for indoor and outdoor use. Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
