This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/496,095 filed on Aug. 18, 2003.
TECHNICAL FIELDThe present invention relates generally to the towing field and, more particularly, to a towing assembly including a hitch ball that is locked in position on a hitch ball receiver such as a hitch bar, draw bar and ball mount head so as to prevent relative rotation of the hitch ball during installation and connection with a hitch ball fastener.
BACKGROUND OF THE INVENTIONTrailer hitches including a hitch ball for connecting a towing vehicle to a trailer have long been known in the art. Examples of such are disclosed in a number of patents including, for example, U.S. Pat. No. 3,482,856 to Reese, U.S. Pat. No. 3,694,006 to Goode et al., U.S. Pat. No. 3,768,837 to Reese, U.S. Pat. No. 4,033,601 to Lindahl et al. and U.S. Pat. No. 5,375,867 to Kass et al.
Most hitch balls are either directly mounted to (1) a draw bar or (2) a ball mount head carried on a hitch bar by means of a threaded mounting shank and cooperating locking-nut or nut and lock washer. More specifically, the threaded mounting shank extends through an aperture in the draw bar/ball mount head and the locking nut or nut and locking washer combination are snugly tightened against the draw bar/ball mount head to secure the trailer hitch ball in position. While this provides a very adequate connection, many individuals are frustrated when the hitch ball rotates in the hitch ball receiver when attempting to tighten the securing nut. When this occurs, it is not possible to complete the tightening operation unless tools are employed to hold the hitch ball and prevent its rotation.
A need is therefore identified for an improved structural arrangement whereby a hitch ball may be secured against rotation relative to the hitch ball receiver during installation and connection of the fastener to the stem of the hitch ball.
SUMMARY OF THE INVENTIONIn accordance with the purposes of the present invention as described herein, a new and improved towing assembly is provided. That towing assembly includes (a) a hitch ball receiver including a hitch ball mounting aperture and a recess around that aperture; (b) a hitch ball including a base and a mounting shank wherein the base is sized and shaped to be received in the recess; and (c) a fastener engaging the shank and securing the hitch ball to the hitch ball receiver. The hitch ball receiver may take a number of forms including but not limited to a ball mount head such as utilized on a weight distributing trailer hitch assembly and a hitch bar, draw bar or the like which may or may not include a tongue.
More specifically describing the invention, the recess is acircular in shape. Thus, for example, the recess may assume an oval, polygonal, square, rectangular, hexagonal or star shape. If desired, the recess may take the form of a channel. The recess also includes a sidewall engaging the base of the hitch ball. More specifically describing the invention, the hitch ball receiver includes a first face and a second face with the recess being provided in the first face. Still further, the towing assembly includes a second recess. This second recess is provided in the second face. Still further, a spacer is provided. The spacer is sized and shaped to be received in either of the first or second recesses.
In accordance with yet another aspect of the present invention, a method is provided for securing a hitch ball to a hitch ball receiver. The method includes the steps of (a) engaging a base of the hitch ball in an acircular recess in the hitch ball receiver and (b) securing a fastener for the hitch ball while engagement between the base and a sidewall of the recess prevents the hitch ball from rotating.
Advantageously, the engagement of the base of the hitch ball with the sidewall of the acircular recess prevents the hitch ball from rotating relative to the hitch ball receiver as the fastener is connected to the mounting shank of the hitch ball. Where the mounting shank is threaded and the fastener is a nut, this means that only a single wrench is required to secure the hitch ball to the hitch ball receiver. This allows far more convenient connection of the hitch ball to the hitch ball receiver as the user is only required to manipulate one tool to complete the connection process.
Additionally, it must be appreciated that the spacer allows the hitch ball receiver to be adapted to accept and receive a standard hitch ball: that is, one not incorporating a base specifically sized and shaped to be received in the recess. Thus, the hitch ball receiver is sufficiently versatile to receive and hold virtually any size and shape of hitch ball one might be expected to find in the marketplace.
In the following description there is shown and described several embodiments of the invention, simply by way of illustration of some of the modes best suited to carry out the invention. As it will be realized, the invention is capable of other different embodiments and its several details are capable of modification in various, obvious aspects all without departing from the invention. Accordingly, the drawings and descriptions will be regarded as illustrative in nature and not as restrictive.

Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.
DETAILED DESCRIPTION OF THE INVENTIONReference is now made to
A hitch ball mounting aperture 20 is provided in the tongue 16 of the hitch ball receiver 12. A recess 22 is provided around the aperture 20 in a first face 24 of the tongue 16. A second recess 26 is provided around the mounting aperture 20 in a second face 28 of the tongue 16 (see also
The towing assembly 10 also includes a hitch ball 30 including a base 32 and threaded mounting shank 34. In accordance with an important aspect of the present invention, the base 32 is correspondingly sized and shaped to be received and held in either of the recesses 22, 26. Thus, the base 32 just fits in and completely fills the recess. As illustrated in
The towing assembly 10 also includes a fastener 36 for engaging the shank 34 and securing the hitch ball 30 to the hitch ball receiver 12. As illustrated, the fastener 36 assumes the form of a nut 38 and a lock washer 40. Alternatively, a self-locking nut could be utilized.
The hitch ball 30 may be easily and conveniently connected to the hitch ball receiver 12. As illustrated in
As should be appreciated, the hitch ball receiver 12 may be utilized with the tongue directed downward as illustrated in
As best illustrated in
When not in use in connecting a standard hitch ball 46, the spacer 44 may be stored in the recess 22 or 26 on the underside of the tongue 16 opposite the hitch ball 30 (see
