Abstract
This invention relates to a threaded and/or non-threaded split shank for a hitch receiver drawbar, implement, and the like, and a means of securing that split shank to the hitch receiver with the two bolts, one from each side, or with a conventional draw pin. If the split shank is fastened with two bolts, movement between the split shank and hitch receiver is eliminated. The absence of movement prevents the hitch receiver and the implement shank from wearing out, and greatly reduces the chances of the implement shank rusting solid in the hitch receiver tube. The split shank also adds overall strength and reinforcement to the hitch receiver.

THREADEDINON-THREADED SPLIT SHANK
FOR HITCHES, DRAWBARS. AND THE LIKE
Field of the Invention This invention relates to a threaded and/or non-threaded split shank for a hitch receiver drawbar, implement, and the like, and a means of securing that split shank to the hitch receiver with two bolts, one from each side, or with a conventional draw pin. If the split shank is fastened with two bolts, movement between the split shank and hitch receiver is eliminated. The absence of movement prevents the hitch receiver and the implement shank from wearing out, and greatly reduces the chances of the implement shank rusting solid in the hitch receiver tube. The split shank also adds overall strength and reinforcement to the hitch receiver.
Back rg o Two-part hitches usually comprise a detachable drawbar, equalizer hitch implement, and the like, that typically have either a hollow tube type shank or a solid type shank, which shank fits into a permanent square tube hitch receiver secured to the vehicle. The solid shank is durable and is preferred over a hollow tube type shank in heavy duty applications. In heavy duty applications, the holes in the tube type shank wear badly. The implement shank is secured to the hitch receiver by a detachable draw pin, which holds the two parts together. When not in use, the implement shank can be detached from the hitch receiver by withdrawing the draw pin.

The solid shank is durable and is preferred over a hollow tube type shank in heavy duty applications. In heavy duty applications, the holes in the tube type shank wear badly. The implement shank is secured to the hitch receiver by a detachable draw pin, which holds the two parts together. When not in use, the implement shank can be detached from the hitch receiver by withdrawing the draw pin.
Prior methods of attaching implements with either hollow tube type shanks or solid shanks to square tube hitch receivers have many disadvantages. In the case of the hollow tube type shank, when a conventional securing or draw pin is used, it is common for the holes in both the implement tube and the hitch receiver to become elongated over time due to frequent load yanking of the implement shank in the hitch receiver. This is caused by the constant starting and stopping of the towing vehicle, and the weight placed on the hitch.
This constant yanking also causes slack and undesirable movement to develop between the square shank of the implement and the surround-ing square tube of the hitch receiver. In the case of the solid shank, when a conventional securing or draw pin is used, it is common for the holes in only the hitch receiver to become elongated over time for the same reasons. This also causes slack and undesirable movement to develop between the square shank of the implement and the surround-ing square tube of the hitch receiver. In the case of the hollow tube type shank, in an effort to reduce the slack and stabilize the imple-ment, it is common practice to install a second apparatus such as a collar that may contain one or more bolts that are tightened against the outside of the square tube walls of the hitch receiver. Another alterna-tive is to use a wedge-shaped device that is inserted between the walls of the square tube of the implement and the square tube of the hitch receiver. In the case of the solid shank used in heavy duty applica-tions, stabilizing collars and wedges are seldom utilized in that they are light duty in nature.
This constant yanking also causes slack and undesirable movement to develop between the square shank of the implement and the surround-ing square tube of the hitch receiver. In the case of the solid shank, when a conventional securing or draw pin is used, it is common for the holes in only the hitch receiver to become elongated over time for the same reasons.

In the case of the solid shank used in heavy duty applica-tions, stabilizing collars and wedges are seldom utilized in that they are light duty in nature.
Apart from the problems where the hitch receiver becomes stretched and the draw pin holes elongated, there is a security problem associated with the conventional draw pin. This is because the draw pin is easily removed and therefore makes an easy theft target. Locks for draw pins have been developed, but these locks are subject to corrosion from road grit, salt and weather elements, and hence the locks become unworkable over time. Such locks are also easily broken or damaged, thereby rendering them ineffective.
Another problem with the hollow tube type shank imple-ments and solid shank implements, and square tube hitch receivers is that in the case of the hollow tube type shank, both tubes become concave on the sides if a single long bolt is used to fasten the two parts together. In the case of the solid shank, only the hitch receiver tube will become concave if fastened in the same fashion. This happens when the single bolt is passed through the sidewalls of both the implement shank and the hitch receiver. The long bolt is secured with a nut which is tightened from one side only. The tightening of the single nut on the long bolt forces the sidewalk of one, or both, tubes together. While such tightening will marginally reduce side to side slack and movement, it will not reduce up and down slack and movement. The irregular distorted concave shape of one, or both, tubes may cause some difficulty in attempting to separate the imple-ment shank from the hitch receiver.
Another common problem with hollow tube type shank implements and solid shank implements, and square tube hitch receivers, is that the two parts will rust solidly together if connected for an extended length of time, thereby making it virtually impossible to separate the two. This happens when the elements, rain, salt, road grit, etc., enter between the inner walls of the hitch receiver and the outer walls of the solid shank thereby allowing rust to form. The rust expands in the small space between the shank and the hitch receiver and solidifies, in effect making the two parts one solid piece.
Attempts to prevent rust from forming include painting or plating, and greasing the shank. All of these are worn off very quickly due to the constant movement between the implement shank and hitch receiver, and will not prevent rust from forming over the long term.
Summary of Invention A split shank is secured to a drawbar, equalizer hitch, and the like. The two sides of the shank are tapered slightly towards the back end. They are stabilized, and spaced, with an angular bracket at the front end. Each piece of the shank has threaded holes along the side for securing it to the hitch receiver with a bolt and lock washer from each side. There are also non-threaded holes for securing the shank to the hitch receiver with the conventional draw pin in the case of frequent installation and removal. With the hollow split square tube, it is installed with a hitch receiver/implement threaded fastening assembly.
To install, the split shank of the implement is placed in the square tube of the hitch receiver, and the holes in the side of the sidewalk of the hitch receiver are aligned with the threaded holes in the sidewalls of the split shank of the implement. Two bolts are then inserted, one from each side, along with lock washers, and are tightened in the threads of the sidewalls to conventional tightness.
To connect the hollow tube split shank and the hitch receiver, the square shaped split tube is placed in the square tube of the hitch receiver, the holes in the side of the sidewalls of the hitch receiver are aligned with the threaded holes in the sidewalls of the implement. The two bolts are then inserted, one from each side, along with lock washers, and are tightened in the nuts to conventional tightness .
The invention is directed to a split shank for detachably securing into a hitch receiver comprising: (a) a first elongated shank extending longitudinally from an implement; (b) a second elon-gated shank extending longitudinally from the implement, adjacent the first shank; (c) a first hole formed in the first shank; and (d) a second hole formed in the second shank in alignment with the first hole.
The first shank and the second shank can taper towards each other at the ends opposite the ends which are connected to the implement. A plurality of aligned holes can be formed in the first shank and the second shank. One of the plurality of holes can be threaded.
Another problem with the hollow tube type shank imple-ments and solid shank implements, and square tube hitch receivers is that in the case of the hollow tube type shank, both tubes become concave on the sides if a single long bolt is used to fasten the two parts together.

Figure 1 illustrates a perspective view of the novel split shank implement.
Figure 2 illustrates a section view of a split shank in a square tube hitch receiver, the two parts being secured together by a pair of bolts .
Figure 3 illustrates a perspective view of a second design of a split shank. The split shank is in the form of a split square tube.
Description The invention is directed to a threaded and/or non-threaded split shank for a hitch receiver drawbar, implement, and the like, and a means of securing that split shank to the hitch receiver with two bolts, one from each side, or with a conventional draw pin. The invention eliminates the need to use a conventional securing or draw pin to secure the implement shank in the hitch receiver. The disadvan-tages inherent in connecting a conventional implement with a conven-tional hitch receiver using a conventional draw pin are eliminated by using the dual bolt securing system provided within the split shank.
The hitch receiver/implement threaded fastening assembly and split hollow square tube has similar advantages.
Figure 1 illustrates a perspective view of the novel split shank implement. As seen in Figure 1, the split shank 2 is constructed of an implement 4 with a pair of near parallel shanks 6 and 8 extend-ing longitudinally from one side thereof. The pair of shanks 6 and 8 have three holes 10, 12 and 14 drilled therethrough. Holes 12 are threaded. The implement 4 also can have one or more vertically arranged holes drilled therethrough, if required. The implement 4 can be a towbar, a bike rack, or the like.
Figure 2 illustrates a section view of a split shank in a square tube hitch receiver, the two parts being secured together by a pair of bolts. As seen in Figure 2, the split shank 6,8 is secured to the square tube 16 of the hitch receiver by utilizing two bolts 18,20, one bolt being inserted in each side of the sidewalls of the hitch receiver 16 and tightened in the threads of the middle holes 12 in the split shank 6,8. By using the threaded securing system within the split shank 6,8, the walls of the split shank implement 6,8 and the hitch receiver 16 are tightly cinched together and movement or slack is eliminated. This prevents movement and attendant wear on the split shank implement 6, 8 and the hitch receiver 16 because the split shank implement 6,8 is held steady in position in the hitch receiver 16.
Theft is deterred because a wrench is required to remove the two securing bolts 18,20 and this is time consuming.
The sidewalls of the hitch receiver do not become dis-toned or concave in shape because the split shank implement 6, 8 and the hitch receiver 16 are secured together by utilizing two bolts 18,20, one from each side, rather than a single bolt which threads from one side of the hitch receiver to the other and is secured with a single nut.
Figure 3 illustrates a perspective view of a second design of a split shank. The split shank is in the form of a split square tube 22 which has a pair of slots 24 in the top and bottom thereof. To have the same advantages and to function in the same way as the split shank 6, 8 shown in Figure 1, the split hollow tube type shank shown in Figure 3 must be bolted in with a hitch receiver/implement threaded fastening assembly (not shown) because the walls of the square tube are not thick enough to have a threaded hole.
The split shank according to the invention has a number of advantages, as follows:
(1) The split shank 6, 8 is tapered and is thus easier to insert into the hitch receiver. The split shank 6, 8 has a "spr-ing" action. When the bolts are tightened, it "opens up"
to fit the inside of the hitch receiver tubing 16. When the bolts are loosened, it moves away from the sidewalk of the hitch receiver 16 and is easier to remove. The tapered split shank 6, 8 also facilitates removal if it is rusted in the hitch receiver 16.
(2) The split shank 6, 8 can be plated or painted, and greased prior to insertion in the hitch receiver 16, and with no movement, rust is virtually eliminated.
(3) The outer edges of the split shank 6, 8 are square and when they are fastened tight with the two bolts 18,20, these edges tighten into the rounded corners of the hitch receiver 16 and prevent any up and down and side to side movement of the shank 6, 8.
(4) The split shank, when bolted into the hitch receiver 16, serves as a reinforcement to the tube of the hitch receiver 16, thereby adding strength to the hitch receiver 16.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
