Description:
BACKGROUND 
     1. Technical Field 
     Aspects of this document relate generally to apparatuses for lifting, moving, or otherwise transporting bales of hay. 
     2. Background Art 
     Various types of vehicles are frequently used to transport bales of hay. Vehicles used in the transport of hay typically include flatbeds or hay retrievers. As the name implies, flatbed vehicles usually include a truck with a flatbed that requires a forklift or other device to stack bales of hay on the flat bed before the bales of hay are transported. Hay retrievers typically include a bed that pivots from the truck frame to secure a fixed amount of hay bales in a stack before pivoting back to the truck frame. Hay retrievers, however, are limited to a specific number of hay bales present in a stack. Moreover, the structure of the bed in previous hay retrievers limits the pivoting movement of the bed, thus confining the functionality of the hay retriever to relatively few uses.

     DESCRIPTION 
     This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended hay retriever and/or assembly procedures for a hay retriever will become apparent for use with implementations of a hay retriever from this disclosure. Accordingly, for example, although particular hay retrievers are disclosed, such hay retrievers and implementing components may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such hay retrievers and implementing components, consistent with the intended operation of hay retrievers. 
     Various aspects of embodiments disclosed herein assist in the retrieval, loading, and/or unloading of baled hay. As such, embodiments of disclosures presented herein are, in one aspect, associated with a vehicle  50  capable of holding and transporting bales of hay. As shown in  FIGS. 1-8 , the vehicle  50  may comprise any vehicle configured to couple to various embodiments of the base frame  100 , carriage assembly  300 , and/or the fork assembly  200  presented herein. In a particular embodiment, the vehicle  50  comprises at least two vehicle beams  45  extending from a rear of the vehicle to at least the vehicle cab  55 . Vehicle beams  45  typically comprise metal beams known in the art. 
     In one aspect, vehicle  50  comprises a rear axle  40  coupled to the vehicle beams  45  opposite the vehicle cab  55 . Rear axle  40  is typically located near the rear of the vehicle  50 , but may, in various embodiments, be located anywhere along the vehicle beams  45 . Rear axle  40  is coupled to a plurality of wheels that may, in some embodiments, be in mechanical communication with a vehicle engine. Similarly, vehicle  50  further comprises a front axle proximate the vehicle cab  50 . Front axle  40  is likewise coupled to a plurality of wheels that may, in some embodiments, be in mechanical communication with the vehicle engine. The vehicle engine and/or battery may power the vehicle and any associated hydraulic or mechanical lifts through a variety of mechanisms known in the art. 
     In an embodiment, the hay retriever  10  comprises a base frame  100  coupled to the at least two vehicle beams  45 . According to one aspect, base frame  100  comprises a pivot elements  115  coupled to vehicle beams  45  proximate the rear of the vehicle  50 . In such an aspect, the base frame  100  further comprises two opposing side members  105  that are coupled to or otherwise extend from pivot elements  115  to a rear member  110 . 
     In another embodiment, hay retriever  10  comprises a base frame  100  with two base beams that align with the vehicle beams  45  when the base frame  100  is in a horizontal first frame position  150 . Although reference is made to a base frame  100  comprising two base beams, embodiments comprising one, two, three, four, or more base beams  150  are also contemplated. In one aspect, the base beams are coupled to the rear member  110  and the pivot elements  115  between the rear member  110  and the pivot elements  115 . 
     An embodiment comprising base beams may further comprise two opposing side members  105  similarly coupled to the rear member  110  and the pivot elements  115  between the rear member  110  and the pivot elements  115 . While base beams are typically more centrally located relative the pivot elements  115 , side members  105  are typically located on opposing ends of pivot elements  115 . In other embodiments, however, base beams may be situated or otherwise located anywhere between opposing ends of the pivot elements  115  and/or rear member  110 . Although included in most embodiments of base frame  100 , rear member  110  is not required in some embodiments. 
     According to various aspects, rear member  110  comprises one continuous rear member  110  that extends between side members  105 , or alternatively two separate rear members  110 . In an embodiment comprising two separate rear members  110 , each rear member  110  is typically coupled to a side member  105  and either a vehicle beam  45  or a base beam. Furthermore, any of the embodiments disclosed throughout this document may further comprise additional cross beams, support members, and the like on base frame  100  that provide structural support necessary in use of the base frame  100  in retrieving and hauling bales of hay. 
     In an embodiment, hay retriever  10  further comprises a lifting element  35  coupled to the vehicle  50  and configured to pivot or otherwise move base frame  100  from a substantially horizontal first frame position (shown in  FIG. 1 ) to a substantially vertical second frame position (shown in  FIG. 2 ). Typically, lifting element  35  is coupled to vehicle beams  45 . In the embodiments shown in  FIG. 1-9 , however, lifting element  35  is coupled to a lift mount  60  that extends between vehicles beams  45 . Lifting element  35  may comprise any type of lifting device or apparatus, such as but not limited to a hydraulic lift, a chain lift, and the like. In a particular embodiment, two hydraulic cylinders are coupled to the vehicle  50  proximate to the rear axle  40 . As the piston rods extend, the base frame  100  rotates or pivots to the substantially vertical second frame position shown in  FIG. 2 . As the piston rods refract, the base frame  100  returns to the substantially horizontal first frame position shown in  FIG. 1 . 
     In an embodiment, hay retriever  10  further comprises a rear wall frame  400 . One aspect of the rear wall frame  400  comprises vertical beams, diagonal beams, and horizontal beams. The rear wall frame  400  is, in some embodiments, movably coupled to the base frame  100  such that the rear wall frame  400  is moveable between a first rear wall frame position proximate to the rear member  110  to a second rear wall frame position distal to the rear member  110 . 
     In an embodiment, rear wall frame  400  couples to base frame  100  with sleeves coupled to the opposing side members  105 . For example, a sleeve on each side of the rear wall frame  400  surrounds a portion of one of the opposing side members  105  and is configured to slide along the respective side members  105 . When each of the two sleeves on the rear wall frame  400  slide or otherwise move along the respective opposing side members  105 , the rear wall frame  400  moves between a first rear wall frame position and a second rear wall frame position. The first rear wall frame position and the second rear wall frame position may be located anywhere along the opposing side members  105 . In a particular embodiment, the first rear wall frame position is proximate to the rear member  110 , and the second rear wall frame position is distal to the rear member  110  near the end of opposing side members  105  opposite the rear member  110 . 
     In one aspect, the sleeves comprise a hole or aperture shaped to allow passage of one of the side members  105  through the hole or aperture. The hole or aperture on sleeve may, in some embodiments, be shaped similar to the cross section of the opposing side members. Typically, the sliding motion of the sleeves of rear wall frame  400  is enabled by wheels coupled to the sleeves and in contact with opposing side members  105 . In other embodiments, the movement of the sleeves of rear wall frame  400  is accomplished without wheels. 
     The sliding motion that moves sleeves along opposing side members  105  is typically powered by hydraulic cylinders. As the piston rods contract, the wheels roll or the sleeves slide along opposing side members  105  causing the rear wall frame  400  to move from first rear wall frame position  450  proximate to the vehicle cab  55  to the second rear wall frame position distal to the vehicle cab  55 . As the piston rods extend, the wheels roll in the opposite direction returning the rear wall frame  400  to the first rear wall frame position. The controls for such motion are within vehicle  50 . In other embodiments, the sliding motion of the sleeves along opposing side members  105  is accomplished through other mechanical mechanisms, such as, but not limited to, gears, chains, levers, and the like. 
     In another embodiment, rear wall frame  400  couples to base beams  120  in a similar manner as rear wall frame  400  may couple to opposing side members  105 . Accordingly, sleeves may interact or otherwise slide along base beams. In yet another embodiment, base beams may comprise extendable pistons which couple to rear wall frame  400 . 
     In an embodiment, hay retriever  10  further comprises carriage assembly  300 . In one aspect, carriage assembly  300  couples to base frame  100  at the front member  115 . Carriage assembly  300  is rotatable between a substantially horizontal first carriage position (shown in  FIG. 1 ) and a substantially vertical second carriage position (shown in  FIGS. 3 and 4 ). In a preferred embodiment, carriage assembly  300  can rotate either in conjunction with base frame  100  or independently. 
     As shown in  FIG. 9 , an embodiment of hay retriever  10  comprises two locking mechanisms  160 . According to one aspect, each locking mechanism  160  extends between a side member  105  and a carriage frame member  310  of the carriage assembly  300 . When the locking mechanism  160  is in a locked position, the base frame  100  and the carriage assembly  300  rotate simultaneously at the same rate as the lifting element  35  lifts the carriage assembly. When the locking mechanism  160  is in an unlocked position, the only the carriage assembly  300  rotates or pivots, while the base frame  100  remains effectively motionless. When in an unlocked position, the locking mechanism  160  is disengaged from the carriage assembly. In various embodiments, the locking mechanisms  160  may comprise an air brake assembly, an electric locking mechanism, or a hydraulic powered locking mechanism. In a specific embodiment, the locking mechanisms  160  comprise air brake assemblies that utilize the vehicles brake compressor. The base frame  100  and/or the carriage assembly  300  may further comprise holes or other attaching components configured to couple with a pin of the locking mechanisms  160 . 
     As further shown in  FIG. 9 , in an embodiment, carriage assembly  300  comprises a base plate  305 , at least two carriage frame members  310 , at least two extension frame members  315 , at least one carriage hydraulic cylinder  320 , a fork body  330 , and at least one cross brace  335 . The base plate  305  is typically coupled to the carriage frame members  310 , which extend perpendicularly from the same inward side of the base plate  305 . Although two carriage frame members  310  are typically utilized, carriage assemblies  300  utilizing more than two carriage frame members  310  are also contemplated. Carriage frame members  310  are, in one aspect, also coupled to the lifting element  35  previously described. 
     In a particular embodiment, carriage assembly  300  further comprises extension frame members  315  configured to extend the length of carriage assembly  300 . In a particular aspect of such an embodiment, carriage frame members  310  are coupled to extension frame members  315  such that the extension frame members  315  slide along carriage assembly wheels  360  to extend from and retract into the carriage frame members  310 . In other aspects, carriage assembly wheels  360  are not necessary for extension frame members  315  to slide along carriage frame members  315 . 
     At least one cross brace  335  may also be included in carriage assembly  300  to support the carriage frame members  310 . Fork body  330  couples to the extension frame members  315  such that fork body  330  may slide along the extension frame members  315 . As shown in  FIGS. 5 and 9 , one embodiment utilizes at least one hydraulic element  340  mounted to the carriage assembly  300  to extend and retract the extension frame members  315 , as well as move the fork body  330  along the extension frame member  315  or the carriage frame members  310 . In some embodiments, carriage frame members  310  and extension frame members  315  comprise C-channels that, in combination with rollers, allow extension frame member  315  to extend from carriage frame members  310  as hydraulic element  340  extends. 
     Fork body  330  is typically slidably coupled to extension frame members  315  and moves in mechanical cooperation with extension or retraction of extension frame members  315 . For example, movement of hydraulic element  340  may, in some embodiments, actuate a chain and pulley system that moves the fork body  330  and the extension frame members  315 . In other embodiments, hydraulic element  340  may directly move extension frame members  315 , and the chain and pulley system may responsively move the fork body  330  along extension frame members  315 . In still other embodiments, movement of extension frame members  315  and fork body  330  is accomplished through any other movement mechanisms apparent to one having skill in the art. 
     Hydraulic element  340  typically includes a hydraulic housing and a hydraulic piston that, upon actuation, extends out from the hydraulic housing. In a preferred embodiment carriage hydraulic extension  340  is a 48 inch stroke hydraulic cylinder, though other modes of power may also be used. In other embodiments, a chain lift or a series of gears may be utilized to move extend and retract the extension frame members  315  and/or move the fork body  330 . 
     In an embodiment, carriage assembly  300  also couples to fork assembly  200 . In a preferred embodiment fork assembly  200  is coupled to carriage assembly  300  via fork body  330 . Fork assembly  200  comprises two fork hydraulic cylinders  210  which extend horizontally from the fork body  330  in opposite directions and two arms  205  which extend from the fork hydraulic cylinders  210  at a 90 degree angle, the two arms  205  and the fork hydraulic cylinders  210  forming a plane perpendicular with the plane of the carriage assembly  300 . 
     In a preferred embodiment the two fork hydraulic cylinders  210  in hydraulic housings  215  are 30 inch stroke hydraulic cylinders, though other modes of power may also be used. As shown in  FIGS. 7 and 8 , operation of the fork hydraulic cylinders  210  moves the arms  205  laterally such that the distance between the arms  205  may be increased or decreased. The arms  205  also move parallel with the plane of the carriage assembly  300  in conjunction with the movement of the fork body  330  and the extension frame members  315 .  FIG. 8  illustrates arms  205  in a first or narrowed fork assembly position, with the arms  205  closer to the base plate  305 .  FIG. 7  illustrates arms  205  have moved to a second or wider fork assembly position, with the arms  205  further from each other and base plate  305 . In a preferred embodiment the two arms  205  have an L-shaped cross section. 
     In an embodiment, the rear wall frame  400  further comprises two cords coupled to the rear wall frame which are attachable to the ends of arms  205 . Cords are adjustable to different lengths and may comprise any type of cord, such as, but not limited to, ropes, chains, cables, straps, or like cords known in the art. 
     In a preferred embodiment the hay retriever  10  may be used for retrieving a hay stack of various heights, transporting a hay stack of various heights, and splitting a hay stack to a desired height. Loading haystacks comprised of large bales of hay onto a truck can be difficult and time-consuming. Hay retriever  10  allows an entire haystack to be loaded in a single motion. The base frame  100  and carriage assembly  300  are rotated from the substantially horizontal first position to the substantially vertical second position. The vehicle  50  then backs up until the arms  205  of the fork assembly  200  are on opposite sides of the haystack. The arms  205  are moved laterally inward such that each of the L-shaped arms  205  is on an opposite bottom corner of the haystack. The base frame  100  and carriage assembly  300  are rotated back slightly. In an embodiment with a moveable rear wall frame  400 , the rear wall frame  400  moves from a first rear wall frame position toward the second rear wall frame position until the rear wall frame  400  abuts the top of the haystack. In addition, or alternatively, the arms  205  are moved away from the first fork assembly position  250  lifting the haystack toward the rear wall frame  400 . The cords are then attached to the ends of the arms  205  and adjusted to the appropriate length of approximately the height of the haystack. The base frame  100  and carriage assembly  300  are then returned to the substantially horizontal first position,  150  and  350  respectively. The haystack may be transported to its new destination. 
     To unload the haystack, the base frame  100  and carriage assembly are rotated to the substantially vertical second position, and the arms  205  return to the first fork assembly position such that the haystack is on the ground. The arms  205  then move laterally outward and the rear wall frame  400  returns to the first rear wall frame position such that the haystack is standing without support of the hay retriever  10 . 
     The hay retriever  10  may also split haystacks into smaller haystacks. The carriage assembly  300  rotates to the substantially vertical second carriage position while the base frame  100  remains in the substantially horizontal first frame position. The arms  205  are lifted toward the second fork assembly position  255  away from the base plate  305  until the arms  205  are even with the desired splitting location of the haystack. The vehicle  50  then backs up such that the arms  205  are on opposite sides of the haystack. The arms  205  move laterally inward until the arms  205  have wedged into the haystack. The arms  205  are lifted higher to split the haystack. This smaller haystack may be moved to a new desired location. 
     At the new desired location the arms  205  are lowered until the haystack is on the ground and the arms  205  are then moved laterally outward such that the haystack is standing without support of the hay retriever  10 . The carriage assembly  300  is returned to the substantially horizontal first carriage position. 
     It will be understood that implementations are not limited to the specific components disclosed herein, as virtually any components consistent with the intended operation of a method and/or system implementation for hay retrievers may be utilized. Accordingly, for example, although particular hydraulic systems, frames, pivot elements, and arms may be disclosed, such components may comprise any shape, size, style, type, model, version, class, grade, measurement, concentration, material, weight, quantity, and/or the like consistent with the intended operation of a method and/or system implementation for a hay retriever may be used. 
     In places where the description above refers to particular implementations of a hay retriever, it should be readily apparent that a number of modifications may be made without departing from the spirit thereof and that these implementations may be applied to other hay retrievers. The accompanying claims are intended to cover such modifications as would fall within the true spirit and scope of the disclosure set forth in this document. The presently disclosed implementations are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the disclosure being indicated by the appended claims rather than the foregoing description. All changes that come within the meaning of and range of equivalency of the claims are intended to be embraced therein.
