     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates to trailer hitch ball mounts. More particularly, the present invention relates to the ball mount, the hitch ball, and accessory receiver tubes having a mount for mounting on (1) the shank of trailer hitch ball mounts, (2) the shank of hitch accessories, including but not limited to the accessories described herein below, or (3) the shank or body of receiver/ball mount extensions. 
         [0004]    2. Description of the Related Art 
         [0005]    In recent years, the number and variety of automotive and truck accessories and attachments that are secured to a vehicle via a hitch receiver has increased. However, use of these accessories has been limited since a conventional receiver-type hitch historically consisted of only a single receiver tube. As such, utilizing an accessory precluded the ability to tow since use of an accessory necessitated removing the ball mount to insert a different accessory, such as a bicycle carrier, canoe rack, step, carry all, etc. It would be desirable to provide for the attachment of multiple accessories or at least one accessory to a trailer hitch ball mount or the like, allowing the trailer tongue to remain hitched to the hitch ball while maintaining the accessory supported for use. 
         [0006]    Additionally, although some all-terrain-vehicle (ATV) manufacturers have begun installing hitch receivers, as opposed to hitch bars, on their ATVs, due to a hitch&#39;s mutually exclusive use design, most ATV accessories continue to be designed to attach to the ATV&#39;s rack system, leaving the single receiver hitch cavity available for its primary intended purpose, i.e., housing a ball mount for towing. 
         [0007]    Although accessory attachment via the rack can be effective, with few exceptions, the accessories are generally not quickly attached or detached. They are generally bolted to the rack system and require the use of tools for installation and removal. 
         [0008]    As can easily be recognized by one skilled in the art, hitch assemblies, attachments, accessories and implements for ATVs and lawn and garden tractors need not necessarily be of the same strength and/or rating s those designed for automotive use. Hitch assemblies and attachments for these off-road tow vehicles may be designed from less-expensive, lighter-duty materials and still function properly and serve their intended purpose. However, some hitch manufacturers are reluctant to produce less-expensive hitch assemblies and attachments made exclusively for ATV and/or lawn and garden tractor use, considering consumers unskilled in the art could inadvertently and inappropriately use a lighter-duty assembly not designed for automotive use on a car, truck, sport utility vehicle, etc., creating an unsafe condition. The misuse of a less-expensive hitch assembly designed exclusively for off-road use can be avoided, however, by modifying a standard feature on most conventional receiver-type hitches and corresponding ball mounts, draw bars, etc. 
         [0009]    Thus, a multi-task trailer hitch assembly solving at least some of the aforementioned problems is desired. 
       SUMMARY OF THE INVENTION 
       [0010]    An attachable and/or removable multi-task trailer hitch extension accessory assembly is configured to attach to a tow ball shank of a ball mount assembly. The extension accessory assembly comprises a ball mount extension platform comprising (A) a midsection comprising a first throughbore for attaching the extension platform to a tow ball shank of a ball mount assembly; (B) a forward end; (C) a rearward end comprising a second throughbore, wherein the rearward end and second throughbore are positioned rearward of a rearward end of a ball mount assembly when the extension assembly is attached to a ball mount assembly, wherein said second throughbore is configured to engage a clevis pin for the connection of accessories; (D) at least one support member attached to the extension platform positioned between the first throughbore and forward end and configured to contact, attach to, or is part of a ball mount assembly such that when the extension assembly is attached to a ball mount assembly, said support member assists in retaining the extension platform in position; and (E) at least one additional accessory attachment device attached to the extension platform. The additional attachment allows the attachment of tow chains, straps, bungee cords, tow hooks and the like. 
         [0011]    A multi-function, anti-rotational, power-sports utility hitch assembly comprises a four-sided hollow receiver tube comprising a forward end configured to attach to a tow vehicle, a rearward end configured to engage a shank, at least one set of aligned apertures in opposing sidewalls between the forward end and the rearward end for securing a hitch accessory shank within the receiver tube by inserting a hitch-pin through apertures, an adjustable tightening bar attachable to an underside of the hitch receiver tube for maintaining the receiver tube in a stationary position when the receiver tube is installed on a tow vehicle, and a tow loop for attaching tow chains, straps, bungee cords, tow hooks and the like to the receiver.

A flat bar platform is attached to the second rearward end of the shank, the platform extending rearward of and parallel with the shank and having a throughbore, e.g., for engaging a clevis pin for the connection of accessories. A tow ball is attached to the second rearward end of the shank and is positioned forward of and above the platform throughbore. A third attachment device is attached to the second rearward end of the shank, e.g., for attaching tow chains, straps, bungee cords, tow hooks and the like. 
         [0012]    A multi-function, anti-rotational, power-sports utility hitch receiver assembly comprises a four-sided hollow receiver tube having a forward end configured to attach to a tow vehicle and a rearward end configured to house an attachment of an accessory shank. Aligned apertures are present in the opposing sidewalls between the forward end and the rearward end for securing a hitch accessory shank within the receiver tube by inserting a hitch-pin through apertures. A removable, adjustable tightening bar is attachable to an underside of the hitch receiver tube for maintaining the receiver tube in a stationary position when the receiver tube is installed on a tow vehicle by abutting a surface on the tow vehicle. The assembly further comprises a tow loop, e.g., for attaching tow chains, straps, bungee cords, tow hooks and the like to the receiver. 
         [0013]    A multi-function, anti-rotational, power-sports utility hitch assembly comprises a first forward end configured to attach to a tow vehicle and a second rearward end. A flat bar platform is attached to the second rearward end having a throughbore, e.g., for engaging a clevis pin for the connection of accessories. The platform extends rearward of and substantially parallel to the forward and rearward ends. A second attachment device is attached to second rearward end, e.g., for attaching tow chains, straps, bungee cords, tow hooks and the like. A tow ball mounting surface area is on the second rearward end, and positioned above and forward of the platform throughbore. A removable, adjustable tightening bar is attachable to the hitch assembly for maintaining the hitch assembly in a stationary position when the hitch assembly is installed on a tow vehicle. 
         [0014]    A hitch assembly of the present invention comprises a shank that is configured to engage a hitch receiver. At least one support is connected to the shank. At least one receiver tube is connected to the support and is spaced from the shank. 
         [0015]    A hitch attachment assembly of the present invention comprises a shank collar and is configured to engage a shank. A receiver tube support member extends from the shank collar. At least one first receiver tube is connected to the support. 
         [0016]    Another hitch assembly of the present invention comprises a tongue extender bar having a rear portion and a forward portion. The forward portion has a connecting element configured to engage a hitch bar of a vehicle. A receiver tube support is connected to the rear portion of the tongue extender bar. At least one receiver tube is connected to the receiver tube support. 
         [0017]    A further hitch assembly of the present invention comprises a platform having a ball mount. A shank is connected to the ball mount platform and is configured to engage a hitch receiver. The shank has an upper flange, a lower flange, and a web located between the upper and lower flanges. 
         [0018]    A still further hitch assembly of the present invention comprises a shank collar configured to engage a hitch shank. A receiver tube support member extends from the shank sleeve. At least one first receiver tube is connected to the support. At least one second receiver tube is connected to the support at a spaced distance from the first receiver tube. 
         [0019]    A multi-task trailer hitch assembly of the present invention provides receiving tubes for the attachment of one or more trailer hitch-mounted receiver-type accessories while retaining a trailer hitch for pulling a trailer in the single hitch receiver provided on many trucks and ATVs, as well as a heavier-duty, more versatile ball mount and more secure ball connection. This permits the simultaneous use of multiple accessories while retaining the concurrent ability to tow. The inventive multi-task trailer hitch assembly is easily transferable from truck to ATV to sport utility vehicle (SUV), etc., regardless of vehicle make or model. 
         [0020]    The sizes of square hitch receivers are commonly1¼ inch (3.2 cm) square (Class II), and 2 inches (5 cm) square (Class III). The present invention includes a combination of both 1¼ inch-(3.2 cm) and 2-inch (5 cm) receiver tubes to permit attaching accessories made to fit Class II and Class III hitch receivers. However, it is to be understood that other size receiver tubes could be utilized in the practice of the invention. The present invention can provide multiple receiver tubes both horizontally and vertically and oriented not only toward the rear but also at angles, e.g., right angles, from the ball mount. This permits fastening one or more attachments from not only the rear but also from the top and inwardly from both sides toward the ball mount. Articles, such as extra hitch ball mounts and other towing accessories, may also be conveniently stored in the receiver tubes of the present invention while towing with a particular Class II or Class III hitch ball mount in the appropriate vehicle-mounted hitch receiver. This allows the easy change of ball mounts for use based on the nature, size, and weight of the trailer or item to be towed since a heavy travel trailer requires a larger ball than a light boat or utility trailer. 
         [0021]    The present invention also allows the convenient stowage of unused receiver attachments, such as receiver tow hooks, shackles, adapters, and other ball mounts. 
         [0022]    In various embodiments, one component of the present invention fits over the exposed shank of a ball mount between the ball mount platform and the hitch receiver when the ball mount shank is engaged by the hitch receiver of a vehicle for towing a trailer. This exposed shank is common in the design of many commercial hitch systems. In another embodiment, the same component of the present invention fits over a receiver/ball extension when the use of a receiver/ball mount extension is desirable. In yet another embodiment, as a product improvement, the same component of the present invention fits over or on a hitch accessory other than a ball mount or extension when the use of a different accessory is desirable. 
         [0023]    Owing to the additional weight of the accessories to be supported and to provide a more versatile hitch assembly, in various embodiments, the multi-task trailer hitch assembly also includes a heavier-duty ball mount and more secure ball connection. 
         [0024]    In one embodiment of the invention, a lower 2 inch (5 cm) collar fits over the exposed ball mount shank, and two parallel receiver tubes are supported by side walls extending upwardly from the lower collar, the central receiver tube being of a1¼ inch (3.2 cm) size and an upper receiver tube being of a 2 inch (5 cm) size. The upper receiver tube may also be of a1¼ inch (3.2 cm) size, allowing the inventive assembly to be inverted and the assembly mounted on a 1¼ inch (3.2 cm) shank, the upper tube serving as a shank collar. A tongue-type hitch may be mounted below the shank and ball mount platform, which also serves to keep the inventive assembly from shifting forward or to the rear along the ball mount shank. 
         [0025]    In another embodiment, a hollow cross bar is attached to the lower side of the collar of the first embodiment, the cross bar acting as perpendicular receiver tubes. Additional receiver tubes can be mounted below the respective end portions of the hollow cross bar and open rearwardly. Also, vertical receiver tubes can be mounted on the upper walls at respective end portions of the cross bar and open upwardly. A vertical receiver tube can be provided, which opens upwardly and attaches to the forward portion of the first embodiment described above. 
         [0026]    In another embodiment, hollow cross bars are attached above and below the collar of the first embodiment, the cross bars acting as four perpendicular receiver tubes. Rearward-opening receiver tubes are mounted between upper and lower cross bars near the ends thereof. Upward-opening receiver tubes are mounted to the upper cross bars above the rearward-opening receiver tubes. The side walls of the first embodiment are attached to the center portion of the upper cross bar and extend upward therefrom. 
         [0027]    In other embodiments, the invention as described in the previous three embodiments fits over a receiver/ball mount extension, reducer or adapter, or other hitch accessories, rather than on a ball mount shank when the use of one of these accessories is desirable. 
         [0028]    Another embodiment of the present invention provides receiver tubes mounted on a tongue-type hitch extension for use with ATVs, lawn and garden tractors, and other vehicles having a tongue-type hitch ball mount rather than a hitch receiver. 
         [0029]    It is widely recognized that to permit ease of sliding ball mounts and other accessories into a hitch receiver, the outside dimension of ball mount and accessory shanks are slightly smaller than the inside dimension of receiver tubes in which they are inserted. While this space is desirable for ease of attachment insertion and withdrawal, it is undesirable for achieving snug connections. Too much space between a receiver tube and an accessory shank can cause the accessory to wobble beyond a tolerable amount, and the condition worsens with each subsequent connection. Since the multi-task trailer hitch assembly&#39;s primary purpose is to attach additional accessories, at least some of the embodiments of the multi-task trailer hitch assembly include inventive and conjunctive “shank expander strips” to ensure optimal connections. 
         [0030]    It is an aspect of the invention to provide improved elements and arrangements thereof for the purposes described which is inexpensive, dependable, and fully effective in accomplishing its intended purposes. 
         [0031]    These and other aspects of the present invention will become readily apparent upon further review of the following specification and drawings.

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0055]    As used herein, spatial or directional terms, such as “top”, “bottom”, “left”, “right”, “over” “ ” “, under, front”, “rear” relate to the, and the like, invention as it is shown in the drawing figures. However, it is to be understood that the invention can assume various alternative orientations and, accordingly, such terms are not to be considered as limiting. Further, all numbers expressing dimensions, physical characteristics, and so forth, used in the specification, figures, and claims are to be understood as being modified in all instances by the term “about”. Accordingly, unless indicated to the contrary, the numerical values set forth in the following specification, figures, and claims can vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. The dimensions set forth on the accompanying drawing figures are for one exemplary embodiment of the invention and it is to be understood that the invention is not limited to the specifically disclosed dimensions. 
         [0056]    The multi-task trailer hitch assembly of the present invention allows the attachment of one or more trailer hitch-mounted receiver-type accessories while retaining a trailer hitch for pulling a trailer in the single hitch receiver provided on many trucks and ATVs. The inventive assembly may also be employed for storage of extra hitches of differing types. 
         [0057]    Referring to  FIG. 1 , there is shown an environmental perspective view of a first embodiment of the inventive multi-task trailer hitch assembly system referred to by the reference number  10 . Hitch attachment assembly  10  is shown mounted on standard tube-type hitch mount shank  14  by means of shank collar or sleeve  32  between hitch ball mount platform  12  and hitch receiver R in which the forward end portion of shank  14  is secured by hitch pin P. Ball mount platform  12  is shown having a trailer tongue ball receiver T mounted on ball  16  (see  FIG. 2A ) and mounted by ball shank  18  and ball mounting nuts  20  and  20   a . Hitch receiver R is mounted on vehicle V (shown as an ATV). 
         [0058]    Shank collar  32  has upright receiver tube support members  40  extending upwardly and rearwardly therefrom. An upper 2 inch (5 cm) receiver tube  34  is mounted at the upper ends of support members  40  and is shown as holding shank S of basket attachment B. A hitch pin may be inserted to provide secure attachment of receiver tube  34  over shank S as desired. A 1¼ inch (3.2 cm) central receiver tube  38  is mounted parallel to and between shank collar  32  and upper attachment receiver tube  34  and attached between receiver tube support members  40 , such as by welding. 
         [0059]    Referring to  FIGS. 2A and 3A , there is shown aside elevational view and a perspective view, respectively, of the embodiment of  FIG. 1 , wherein attachment assembly  30  has a lower receiver tube acting as lower collar  32  mounted on inventive hitch mount shank S, an upper receiver tube  34  and a central receiver tube  38  connected by receiver tube support members  40 . Upper receiver tube  34 , central receiver tube  38 , and lower collar  32  are shown having pin bores  44 ,  46 , and  42 , respectively, for receiving hitch pins as desired. Inventive shank S is shown removed from the hitch receiver R and having hitch pin bore  48 . Owing to the additional weight of the accessories to be supported, inventive shank S can be a heavier-duty shank than the standard tube shank but lighter than a solid steel shank. Shank S can be constructed of a heavy-duty 2 inch (5 cm) H-beam and includes upper flange  1 , lower flange  2 , and web  3 . 
         [0060]    As best seen in  FIG. 2A , to provide a more secure ball connection and prevent potential ball spin resulting from ball nut  20  under torque, ball mount platform  12  has broached surfaces  4 , e.g., on both the top and bottom surfaces where the hitch ball mounting surface makes contact with the ball mount platform. Inventive hitch ball  16  also has a corresponding broached surface  5  to interlock with broached surface  4  on ball mount platform  12 . A broached surface on the trailer ball and ball mount extension may be provided in all of the embodiments of the multi-task trailer hitch assembly of the present invention described herein. 
         [0061]    Also shown in  FIG. 2A  is a ball mount platform extension tab  6  (fastened to ball mount platform  12  with the trailer ball shank  18  passing through a bore hole in the forward section of the extension tab and secured with a ball nut  20 ) for attaching a shackle  9  when an unobstructed tow strap connection between tow vehicle and towed vehicle is desirable. Since the ball mount platform extension tab  6  has a throughbore at its rear end section, it can also be used when desirable to tow products containing a bifurcated trailer tongue by removing the shackle and inserting a clevis pin through the holes in the bifurcated trailer tongue and the hole in the ball mount platform extension tab. Ball mount platform extension tab  6  may also have a corresponding broached surface  5 ′ to interlock with the broached surface  4  on the underneath side of ball mount platform  12 . 
         [0062]    In lieu of broached surface  5 ′ on ball mount platform extension tab  6 , the extension tab alternatively may include an adjustable tightening bar  7  secured in place by tightening bolts  8  inserted into threaded bore holes in extension tab  6 , as best seen in  FIG. 3A . Alternate tightening bar  7  has a square end on one end and a concave end on the other end. By removing bolts  8 , the tightening bar can be rotated 180 degrees and either the square end or concave end used to abut the ball mount platform  12  or the like of corresponding shape. Once the ball mount platform extension tab  6  is attached to the ball mount platform  12  and hand tightened, tightening bar  7  is slid forward to make contact with the ball mount platform or the like; bolts  8  are then securely tightened to keep the extension tab  6  tightened securely against the ball mount platform  12  and the ball and nut tightened to proper torque. The tightening bar  7  prevents the ball mount platform extension tab  6  from potentially moving when torque is applied to the rear end portion of the ball mount platform extension tab  6 . 
         [0063]    Ball mount extension tab  6  may be completely flat as illustrated in  FIGS. 2A and 3A  or may alternatively include two symmetrical bends B′, resulting in an offset or drop between the forward section attached to ball mount platform  12  and the rearward section containing shackle mount bore  23  as also shown in  FIG. 3A . 
         [0064]    Attachment assembly  30  may be permanently welded on shank S or mounted by sliding lower collar  32  over shank S as desired. 
         [0065]    As shown in  FIG. 3E , when attachment assembly  30  is permanently welded on shank S, shank collar  32  and central receiver tube  38  may be eliminated from the assembly and one square, or other appropriate shape, receiver tube support member  40  used in lieu of two receiver tube support members  40 . Receiver tube support member  40  and shank S may be made of hollow tubing or solid steel. 
         [0066]    In the embodiment illustrated in  FIG. 3A , receiver tube support members  40  are attached to a lower wall  68  of upper receiver tube  34  by attachment thereto at receiver tube support member upper end portions  50  and to an upper wall  60  of lower collar  32  at receiver tube support member lower end portions  52 . The central receiver tube  38  is attached to inner walls  54  of receiver tube support members  40 , such as by welding. Lower collar  32  is square in cross section, having upper wall  60 , lower wall  62 , and side walls  64 . Upper receiver tube  34  is square in cross section, having upper wall  66 , lower wall  68 , and side walls  70 . Central receiver tube  38  is square in cross section, having side walls  72  connected to the inner sides  54  of receiver tube support members  40 . As shown, the receiver tube assembly  30  is symmetrical and upper receiver tube  34  may be employed as the lower collar by inverting the receiver tube assembly  30 . In addition, inventive hitch attachment assembly  30  can be rotated 180 degrees, resulting in support members  40  extending upwardly and forwardly from shank collar  32  or upwardly and rearwardly from shank collar  32  when also inverted. 
         [0067]    Referring to  FIGS. 2B and 3B , there is shown a side elevational view and a perspective view, respectively, of the embodiment of  FIG. 1  having a tongue-type hitch  120  mounted thereto. Tongue-type hitch  120  has a rear portion  122  having a vertical hitch pin receiving bore  124  therethrough. Tongue rear portion  122  has a rounded rear end  126 . Hitch  120  has a forward portion  128  supported by tongue front support  130   a  attached to shank collar  32  of assembly  30  at its underside as by welding. Front support  130   a  is an inverted U-shaped member opening downward for access for installing the forward portion  128  of tongue-type hitch  120 . 
         [0068]    Tongue-type hitch  120  is attached at its rear by ball shank  18 , ball mounting nut  20 , and pin  21  (see  FIG. 2B ), or more solidly attached with ball mounting nuts  20  (see  FIG. 3B ) and at its forward portion to hitch pin receiver tube  132  receiving the shank of a hitch pin  90  extending through mounting bores in tongue front support  130   a . Hitch pin receiver tube  132  is laterally mounted, e.g., such as by welding along its length, to the upper side of tongue forward portion  128  so as to align with throughbores in receiver tube attachment  134 . 
         [0069]    Forward portion  128  of tongue-type hitch  120  is removably secured to front support  130   a  by inserting the shank of hitch pin  90  through hitch pin receiver tube  132  (see  FIG. 3B  with front support  130   a  partially cut away). Tongue-type hitch  120 , as installed, not only provides for the use of a hitch pin secured trailer tongue or the like but also prevents movement of shank collar  32  along shank S, providing additional stabilization of attachment support assembly  30 . 
         [0070]    Vertical guide bars  140  extend upwardly from each side of tongue forward portion  128  at a point rearward of front support  130   a  and are fastened at the upper end to hitch ball shank S by means of guide bar fastening bolt  142  extending through a throughbore (not shown) in hitch ball shank S and fastened by a nut (not shown).

Safety chain attachment bar  144  has downwardly-angled end portions  146  extending from a center flat portion  148  attached to tongue forward portion  128 . Angled end portions  146  define safety chain attachment bores  150  for attachment of trailer safety chains or the like. The lower ends of vertical guide bars  140  are attached to flat portion  148  of lateral safety chain attachment bar  144  and to the sides of tongue forward portion  128 , as by welding. Vertical guide bars  140  add support for resisting any torque applied to tongue-type hitch  120  around ball shank  18 . 
         [0072]    Referring to  FIG. 3C , there is shown a perspective view of an embodiment similar to that depicted in  FIG. 3A  with a modified inventive ball mount. Ball mount shank S is also constructed of a heavy-duty 2 inch (5 cm) H-beam and includes an upper flange  1 , lower flange  2 , and web  3 . However, in this embodiment, the top flange  1  and lower flange  2  extend rearward of the web  3  and also serve as the ball mount platform  12 . Ball shank  18  is inserted through bore hole in upper flange  1 , through a steel spacer  21 ′, through aligned borehole in lower flange  2 , and tightened with ball nut  20 . As illustrated, lower flange  2  extends rearward of upper flange  1  and, as shown in  FIG. 3C , has an attachment element, such as a bore hole  23  for attaching a shackle  9  (see  FIG. 2A ) when an unobstructed tow strap connection between tow vehicle and towed vehicle is desirable or to tow products containing a bifurcated trailer tongue when desirable. Lower flange  2  also contains two symmetrical bore holes  22  rearward of the rear end of the web for attaching an additional receiver tube assembly as shown in  FIG. 3D . 
         [0073]    Referring to  FIG. 3D , there is shown a perspective view of an embodiment also similar to that depicted in  FIG. 3A  but with an additional dual-receiver tube assembly  24  to provide an even more versatile multi-task trailer hitch assembly.

A 2 inch (5 cm) receiver extender  260  is mounted in upper receiver tube  34 . 
         [0078]    Referring to  FIG. 8 , there is shown a rear perspective view of another embodiment of the multi-task trailer hitch assembly of the present invention referred to by reference number  300 . Attachment assembly  300  includes elements of the embodiments of the attachment assembly  200  as described above having additional structure attached thereto, such as by welding. Attachment assembly  300  includes shank collar  32 , upper attachment receiver tube  34 , central receiver tube  38 , and receiver tube support members  40  having upper cross bar  310  located between shank collar  32  and receiver tube support members  40 . 
         [0079]    In the illustrated embodiment, upper cross bar and attachment receiver tube  310  is tubular, having a square cross section, and co-extends with cross bar and attachment receiver tube  210 . Receiver tube  310  has a central portion  312  and end portions  314  forming end portion attachment receiving mouths  316 . The central portion  312  of cross bar  310  is attached to the upper side of collar  32 , such as by welding. Upward opening attachment receiver tubes  226  are attached to the respective end portions of upper cross bar  310  in a manner similar to their attachment to cross bar and attachment receiver tube  210  in the embodiment  200  described above. 
         [0080]    Rearward opening receiver tubes  240  are attached between upper cross bar  310  and lower cross bar  210  (see description of the embodiment  200  described above and shown in  FIG. 7 ). Spaced hitch safety chain attachments  322  are attached, such as by welding, along the lower wall of cross bar  210 , chain attachment  322  also being useful for attaching tow ropes. A shackle mounting plate  318  is attached, such as by welding, to a location along the rear side wall of upper cross bar  310  so as to support shackle  320  for use in towing by rope or the like. The spaced hitch safety chain attachments  322  and shackle  320  may be similarly attached to cross bar  210  of the embodiment of  FIG. 7 , as desired. Upward opening receiver tube  100  is shown attached to the upper wall of receiver tube  38  at the forward end thereof at connection  102 . Upward opening receiver tube  100  is shown having hitch pin bores  106  in opposed side walls. Carrying handle  324  is attached to upper attachment receiver tube  34  by a hitch pin or the like to carry hitch receiver tube assembly  300  when not in use. Handle  324  may also be rotated forward to receive a shackle or tow hook for towing. A carrying handle  324  may be similarly attached to any of the embodiments of the present invention described herein. 
         [0081]    Tongue-type hitch  120  is shown attached to the shank  14  in a similar manner to that shown in  FIG. 3B , with the exception that tongue front support  130   b  is attached to the front side wall of cross member  210 , tongue front support  130   b  supporting tongue forward portion  128  by means of hitch pin receiver tube  132  (see description above regarding the embodiment of  FIG. 3B ). The feature of the upward opening attachment receiver tube  100  may also be included in the embodiments of  FIGS. 1-4 , above. 
         [0082]    Referring to  FIG. 9A , there is shown a perspective view of another embodiment of  FIG. 1 , similar to that of  FIG. 3A . By modifying the size of lower collar  32 , attachment assembly  30  is mounted on a receiver/ball mount extension/adapter/reducer  260 ′. The use of these accessories, however, reduces the load rating of the hitch up to as much as 50% and, thus, is particularly useful for light duty applications. 
         [0083]    Carrying handle  324  is attached to upper attachment receiver tube  34  by a hitch pin or the like to carry hitch receiver tube assembly  300  when not in use. Handle  324  may also be rotated forward to receive a shackle or tow hook for towing. A carrying handle  324  may be similarly attached to any of the embodiments of the present invention described herein. 
         [0084]    The tube receiver assemblies as described above may be mounted directly to the ball mount shank S or receiver/ball mount extension  260 ′ by welding, negating the need of a shank collar  32 . 
         [0085]    Referring to  FIG. 10 , there is shown a perspective view of another embodiment of the accessory receiver system of the present invention useful with pulling vehicles having tongue-type hitches. Hitch tongue extender system  400  includes a hitch tongue extender bar  410  having a rear end portion  412  and a forward end portion  414 , forward end portion  414  having a hitch tongue connecting bore  430  for connection to hitch tongue H-T by a bolt, star washer, split lock washer and nut, or the like. A section of hitch receiver tube  418  is mounted on hitch tongue extender bar  410 , which, in turn, supports an assembly of receiver tubes, such as that of  FIG. 4 , as shown, or that of  FIGS. 1-3A  as described above. Hitch receiver tube  418  has a vertically-cut rear end portion  420  and a downward-sloping forward end portion  420 ′. Hitch receiver tube  418  has an upper wall  424  supporting the receiver tube assembly, a lower wall  426 , and side walls  428 . Rear end portion of hitch tongue extender bar  410  has a rounded rear end  412  and a hitch ball or pin receiver bore  416  extends through extender bar rear end portion  412  at a point spaced rearward of the respective rear ends of hitch receiver tube  418  and hitch tongue extender bar  410  for mounting a hitch ball or receiving a hitch pin. The receiver tube assembly is mounted an as to angle rearward rather than to the front, however, this is merely a matter of choice depending on available space in the vicinity of the hitch tongue H-T. Alternatively, in lieu of mounting a hitch ball in bore  416 , a separate ball mount may be inserted in receiver tube  418 . 
         [0086]    Referring to  FIGS. 11 and 12 , there is shown a side elevational view and partially exploded perspective view, respectively, of another embodiment similar to the embodiment shown in  FIG. 10  and useful with pulling vehicles having tongue-type hitches. 
         [0087]    Like the embodiment shown in  FIG. 10 , the embodiment shown in  FIGS. 11 and 12  has a hitch tongue extender bar  410  having a rear end portion  412  and a forward end portion  414 , forward end portion  414  having a hitch tongue connecting bore  430  for connection to a vehicle&#39;s hitch bar with a bolt, split lock washer and nut, or the like. Upright receiver tube support members  40  are attached to the rear end portion  412  of hitch tongue extender bar  410  and supports an assembly of receiver tubes, such as that of  FIG. 4  or that of  FIGS. 1-3A , as shown, and as described above. On its underneath side, hitch extender bar  410  contains an adjustable tightening bar  7  secured in place by tightening bolts  8  inserted into threaded bore holes in hitch tongue extender bar  410 . Tightening bar  7  has a square end on one end and a concave end on the other end. By removing bolts  8 , the tightening bar  7  can be rotated 180 degrees and either the square end or concave end used to abut the vehicle&#39;s hitch bar of corresponding shape. Once the hitch assembly is attached to the vehicle&#39;s hitch bar and hand tightened, tightening bar  7  is slid forward to make contact with the vehicle&#39;s hitch bar; bolts  8  are then securely tightened to keep the hitch assembly tightened securely against the vehicle&#39;s hitch bar and the mounting bolt and nut tightened to proper torque. The tightening bar  7  prevents the hitch assembly from potentially moving when torque is applied to the rear end portion of the ball mount. As seen in  FIG. 12 , opposing hitch safety chain loops  415  are attached, such as by welding, to the bottom of tongue extender bar  410 , safety chain loops  415  also being useful for attaching tow ropes, tie-downs, and bungee cords. Except being of shorter length, the ball mount illustrated in this embodiment is identical to the ball mount shown in  FIG. 3C , including corresponding broached surfaces  4  and  5  on both the ball and ball mount platform (upper flange  1 ). When fully inserted into its receiver cavity, lower flange  2  on ball mount abuts the head of the hitch assembly mounting bolt. 
         [0088]    A much more desirable and convenient method of attaching accessories to a vehicle, such as an ATV, is achieved via a trailer hitch mount without sacrificing towing capability with the inventive multi-task trailer hitch assembly described herein. Unlike many ATV accessories whose use is limited to a specific ATV make and model, this multi-task trailer hitch assembly invention can be used on any ATV make or model that has a hitch receiver or hitch bar. 
         [0089]    Referring to  FIG. 13 , there is shown a side elevational view of inventive and conjunctive shank expander strips applicable to all embodiments of this multi-task trailer hitch assembly. Shank expander strips  500  are thin strips of steel approximately 5 inches in length  1  with a width W slightly smaller than shank size (e.g., 15/16 inch (2.4 cm) for use on a standard 1 inch (2.54 cm) shank, 1 3/16 inches (3 cm) for use on a standard 1¼ inches (3.2 cm) shank, and 1 15/16 inches (4.9 cm) for use on a standard 2 inch (5 cm) shank. Shank expander strips vary in thickness T′ beginning with a strip 0.005 inch (0.01 cm) and increasing by multiples of 0.005 inch (0.01 cm) up to a strip 0.050 inch (0.13 cm) thick. The shank expander strips can have a self-adhesive backing covered with backing paper P′ for attaching expander strips to top, bottom, and sides of ball mount or accessory shank when outside shank dimension expansion is necessary to achieve a firm connection in receiver tube. Each shank expander strip has a center bore for aligning with throughbore in ball mount shank, enabling hitch pin to pass through receiver tube, shank expander strips, and ball mount shank without obstruction when fastening ball mount to receiver. 
         [0090]    Referring to  FIG. 14 , there is shown a side elevational view of shank expander strip  500  installed on one side of standard 2 inch (5 cm) ball mount shank S. To determine the thickness of shank expansion strips to be used, ball mount shank S should be inserted into receiver tube and a measurement taken (using expander strips or feeler gauge) of the space between the top of the ball mount shank and top inside wall of receiver tube, noting the results of the measurement. To ensure proper bore hole alignment for inserting hitch pin when fastening ball mount to hitch, shank expander strips equal to or slightly small than half the size of the measurement noted can be installed on the top and bottom of ball mount shank by removing backing paper P′ ( FIG. 13 ) from expander strip and applying shank expander strips to ball mount shank. 
         [0091]    Similarly, to determine the thickness of shank expansion strips to be used on the side(s) of ball mount shank S, the ball mount can be inserted into receiver tube and moved to one side with a measurement taken (using expander strips or feeler gauge) of the space between the side of the ball mount shank and side inside wall of receiver tube, noting the results of the measurement. A shank expander strip equal to or slightly smaller than the size of the measurement noted can be installed on one side of the ball mount shank by removing backing paper P′ ( FIG. 13 ) from expander strip and applying strip to side of ball mount shank. Alternatively, two shank expander strips equal to or slightly smaller than half the size of the measurement noted could be installed by attaching one expander strip to each side of the ball mount shank by removing backing paper P′ ( FIG. 13 ) from expander strip and applying strips to ball mount shank. 
         [0092]    Referring to  FIG. 15 , as a matter of standardization, a hitch pin bore  49  on a conventional 2 inch (5 cm) receiver tube R is customarily located 2½ inches (6.35 cm) forward of the face of the receiver tube to the center of the hitch pin bore. Based upon this standard feature, to permit coupling a ball mount or other accessory shank to the hitch receiver tube with a hitch pin and clip, the hitch pin bore  48  in standard 2 inch (5 cm) ball mounts, drawbars and other accessory shanks is positioned forward on the implement&#39;s shank a minimum distance of 2½ inches (6.35 cm) from any surface (weld, stop block, ball mount platform, etc.) that contacts the face of the receiver tube (shank contact surface) to enable the shank to be inserted far enough into the receiver to align the holes of both the receiver and accessory shank for inserting the pin. 
         [0093]    By placing the hitch pin bore on the receiver of select tow vehicles at the inventive distance of less than 2½ inches (6.35 cm) from the center of the bore to the face of the receiver (e.g., 1½ inch (3.8 cm) to 2¼ inch (5.7 cm)) inventive ball mounts, drawbars and other lighter-duty, less-expensive accessories can be made exclusively for lighter-duty use, and, consequently, be incompatible for unintended, heavier-duty, automotive use. 
         [0094]    With the corresponding hitch pin bore  48  in the shank of the ball mount, or other light-duty accessories, at the inventive distance also less than 2½ inches (6.35 cm) from the center of the bore to the insertion stopping point on the shank, the hitch pin bore hole  48  in the shank of the light-duty accessory will align with the inventive hitch pin hole  49  in the light-duty receiver R, but not align with the hitch pin bore hole in a conventional, heavier-duty, automotive hitch receiver since it will not protrude into the automotive receiver far enough to align the bore holes for connection. The result is that a standard ball mount or other accessory designed for automotive use will be compatible with both an automotive receiver and inventive light-duty receiver, but the inventive lighter-duty ball mount or other accessory will only be compatible with the inventive light-duty receiver and be incompatible for use in a standard, heavier-duty, automotive hitch receiver. 
         [0095]    Therefore, referring to  FIG. 16 , it is an aspect of this invention that at least some of the embodiments of the multi-task trailer hitch assembly include the hitch pin bore hole  48  at the inventive distance of less than 2½ inches (6.35 cm) from the center of the bore  48  to the insertion stopping point on the ball mount or accessory shank and at the inventive distance of less than 2½ inches (6.35 cm) from the center of the bore  49  to the face on the corresponding receiver tube R. 
         [0096]    Although described using a 2-inch (5 cm) hitch assembly, this aspect of the invention is equally applicable to other size receivers and accessories by moving the standard hitch pin bore hole locations on them to a distance less than the industry standard hole location for the respective receiver and ball mount size. 
         [0097]    Alternatively, in lieu of modifying the inventive hitch pin bore hole location, the same inventive result could be achieved by utilizing in both the receiver tube and accessory shank an inventive bore shape and hitch pin of matched shape (see  48  in  FIG. 14 ) differing from a standard round bore hole such as but not limited to D shaped, star shaped, square shaped, pentagon shaped, hexagon shaped, octagon shaped, etc. With this practice of the invention, the inventive ball mount or other accessory would be incompatible for standard automotive use and only be compatible with the inventive off-road receiver. Therefore, at least one of the embodiments of the multi-task trailer hitch assembly may include a non-round hitch pin bore and matching hitch pin (see  48  in  FIG. 14 ) of the aforementioned alternative shapes. 
         [0098]    Also referring to  FIG. 16 , while there is a use or need for utilizing the multi-task ball mount assembly on lawn and garden tractors (e.g., towing a log splitter, lawn and garden cart, roller, aerator, etc., while attaching another accessory such as a hitch mounted basket to simultaneously transport chain saws, gas cans or other hand tools) in the current art, lawn and garden tractors are not equipped with a receiver-type hitch. Lawn and garden tractors generally have a drawbar for connecting an accessory with a bifurcated trailer tongue or for attaching a tow ball. Depending upon the gauge of steel used on the tractor&#39;s rear shroud or draw bar, the tractor may or may not be capable of adequately supporting the embodiment with a single bolt, washer, and nut as shown in  FIGS. 10 and 11 , as the tractor&#39;s draw bar may be susceptible to bending. 
         [0099]    Thus, in lieu of receiver tube assembly being attached to hitch tongue extender bar  410  and secured to a tractor with a single bolt, washer, and not and shown in  FIG. 11 , an assembly of receiver tubes, such as that of  FIG. 1-3A ,  4 ,  11  or  12 , as shown and described above, may be attached to tractor mounting plate  500 ′. The assembly of this embodiment may then be attached to the rear of a tractor T″ with nuts, bolts, and washers  502 . 
         [0100]    Depending upon the configuration of the tractor&#39;s rear shroud or draw bar, tractor mounting plate  500 ′ may be anywhere between a 45° and 90° angle to the receiver tube. 
         [0101]    Alternatively, in lieu of a standard ball mount shank S as shown in  FIGS. 15 and 16  for illustrative purposes, this embodiment may employ the H-beam type ball mount shank S as shown in  FIGS. 2A ,  3 A,  3 C,  11  and  12 . 
         [0102]    The tube receivers and ball mount shanks of the present invention are preferably made of steel or other appropriate materials and may be square, round, or other shape to permit connecting accessories of matched shape. The length of all receiver tubes, support members, hitch bars, cross members, shanks, and shank expander strips may be shortened or lengthened and the distance between all receiver tubes may be increased or decreased as desired. In addition, although all ball mounts illustrated in the drawings are shown as 2 inches (5 cm) square, each embodiment may also be 1¼ inches (3.1 cm) or other appropriate size. Taillights or reflectors may be installed in the rearward opening receiver tubes of the various embodiments of the invention as described above. Gussets and other reinforcement elements (not shown) may be added as desired to the above-described embodiments of the invention and are not considered to be part of the invention. 
         [0103]    In conjunction with the inventive multi-task trailer hitch assembly, the following list (intended to be illustrative and not exhaustive) of accessories can be attached to the trailer hitch without loss of towing capability: additional ball mounts, receiver extension/adapter/reducer, tow ring, shackle, tow hook, bicycle carrier, ski rack, canoe rack, ladder rack, luggage rack, truck extension, spare tire carrier, gas can carrier, steps, carry all, ATV carrier, grill carrier, cargo basket, ATV tie-down system, motorcycle carrier, wheel chair carrier, pet carrier, pet step, light bar, winch mount, generator stand, tree stand holder, bow holder, gun rack, fishing rod carrier, ice auger carrier, bucket carrier, crate carrier, tool carrier, tool box, cargo box, work bench, chain saw carrier, extension cord reel, garden hose reel, and seed and salt spreader. 
         [0104]    In another aspect of the invention as shown in  FIG. 3B , decorative, ornamental, or source indicating indicia  301  can be mounted, either permanently or removably, on the upper surface  302  of the ball mount assembly, such as on the ball mount platform  12 . Other indicia  304 , such as the ball mount assembly manufacturer or the like, can also be mounted, either permanently or removably, on the ball mount assembly, such as on a rear face  306  of the ball mount platform  12 . In one exemplary embodiment, the first indicia  301  can be, for example, a vehicle logo or name that matches the vehicle to which the ball mount assembly is attached. The indicia  301  can be in the form of a conventional decal having an adhesive back that can be attached to the upper surface  302 . Alternatively, the indicia  301  can be a piece having a magnetic back that can be removably attached to the upper surface  302  of the ball mount platform  12 . Thus, in one aspect of the invention, the first indicia  301  can be related to or can identify with the make or model vehicle. For example, if the vehicle to which the towing assembly is attached is a Dodge Ram truck, the indicia  301  can be the word “Dodge” or the conventional ram symbol associated with Dodge Ram trucks. As will be appreciated by one skilled in the art, the ball mount assemblies for other vehicles could have other conventional identifying indicia associated with those vehicles. The other indicia  304  on the rear face  306  of the ball mount platform  12  can identify the manufacturer or seller of the ball mount assembly. The indicia  304  could be on a sticker or plate attached to the ball mount platform  12 . Alternatively, the indicia  304  could be etched, forged, or formed into the metal of the ball mount platform  12  itself. As will be appreciated by one skilled in the art, a piece having a magnetic back as described above could not only be mounted on the ball mount platform  12  but also on any metallic portion of the vehicle itself, such as on the side panels or doors of the vehicle. 
         [0105]    In some conventional ball mount assemblies, the ball mount includes large letters or other symbols identifying the ball mount manufacturer. To the vehicle owner, it may be unattractive or undesirable to have this ball mount advertising indicia prominently displayed on the rear of the vehicle. Thus, it is not uncommon for vehicle owners to remove the ball mount assembly from the collar to which it is attached and replace the ball mount with a hitch plug having, for example, emblems or symbols more aesthetically desirable. Such symbols can include, for example, the vehicle manufacturer symbol or name. However, this requires that the ball mount be removed and either stored at another location or inside the vehicle until the ball mount is needed for use. With the above-described aspect of the invention, the ball mount can be left in place for immediate use if need be without the undesirable aesthetic problems associated with conventional ball mount assemblies. 
         [0106]    It is to be understood that the present invention is not limited to the embodiments described above but encompasses any and all embodiments within the scope of the following claims.
