DETAILED DESCRIPTION

[0023] The following discussion of the embodiments of the disclosure directed to an umbrella connection assembly for securing an umbrella to a vehicle hitch is merely exemplary in nature, and is in no way intended to limit the disclosure or its applications or uses. The following description provides examples of the assemblies, devices, methods of making, and methods of using one or more inventions, and is not intended to limit the scope, application, or uses of any specific invention claimed in this application.

[0024] Relative terms such as lower or bottom; upper or top; upward, outward, or downward; forward or backward; and vertical or horizontal may be used herein to describe one element's relationship to another element illustrated in the figures. It will be understood that relative terms are intended to encompass different orientations in addition to the orientation depicted in the drawings. By way of example, if a component in the drawings is turned over, elements described as being on the bottom of the other elements would then be oriented on top of the other elements. Relative terminology, such as substantially or about, describe the specified materials, steps, parameters, or ranges as well as those that do not materially affect the basic and novel characteristics of the claimed inventions as whole (as would be appreciated by one of ordinary skill in the art).

[0025] FIG. 1 is an illustration of a vehicle 10 that includes a towing hitch 12 secured to the vehicle. The towing hitch 12 includes a square hitch tube 14 that is designed to accept a square tube associated with a ball mount (not shown) having a ball to which, for example, a trailer towing tongue can be coupled to by a hitch pin 16. The hitch 12 is intended to represent any hitch operable to be connect to a towing tongue of a towed object (not shown). An umbrella connection assembly 18 is coupled to the hitch 12. An umbrella 20 having a support post 22 and a canopy 24 is coupled to the assembly 18 opposite to the hitch 12. The assembly 18 can be rotated to change the orientation of the umbrella 20 relative to the vehicle 10 to provide protection from the sun and rain from multiple directions relative to the vehicle 10.

[0026] FIGS. 2-4 show various isometric views of the umbrella connection assembly 18. The assembly 18 includes a single-piece, square tubular hitch arm 30 that is inserted into the hitch tube 14 at one end in the same manner as the ball mount and includes a hitch pin aperture (not shown) that accepts the hitch pin 16. An opposite end of the hitch arm 30 includes a forked knuckle 32 having opposing tabs 34 and 36. The assembly 18 also includes a single piece square tubular support arm 40 having a protrusion 42 at one end, where the arms 30 and 40 are generally oriented parallel to the ground.

[0027] FIG. 5 is a top view of the end of the arm 40 having the protrusion 42. A hitch pin aperture 44 is provided in the arm 40 for holding the hitch pin 16 when the assembly 18 is not coupled to the hitch 12. Some embodiments can include a plurality of hitch pin apertures 44 formed in the sidewalls of the tubular support arm 40 to allow various accessories to be secured to the support arm 40, including, but not limited to, grills, coolers, or toolboxes.

[0028] The assembly 18 also includes a circular tubular umbrella holder arm 46 rigidly coupled to an end of the support arm 40 opposite to the protrusion 42 so that the arm 46 is generally perpendicular to the support arm 40. The umbrella holder arm 46 includes an umbrella post stop 48. The umbrella post stop 48 can be a pin or threaded fastener that extends through the interior of the umbrella holder arm 46 to prevent vertical translation of the umbrella post 22 through the bottom of the arm 46. In other embodiments, the post stop 48 can be a plate or cover that is secured to the bottom end of the umbrella holder arm 46 or that extends through the interior of the umbrella holder arm 46 to prevent vertical translation of the umbrella post 22. The umbrella post 22 is inserted into the umbrella holder arm 46 so that it rests on the post stop 48. The umbrella post 22 can be secured within the umbrella holder arm 46 by screws 50 and 52 threaded through the arm 46 that frictionally engage the umbrella post 22 to apply pressure that holds the umbrella post 22 securely within the arm 46.

[0029] The protrusion 42 is inserted between the tabs 34 and 36 so that an axle pin aperture 54 in the protrusion 42 aligns with axle pin apertures (not shown) in the tabs 34 and 36. An axle pin 60 is inserted through the pin apertures to secure the arms 30 and 40 together in a manner that allows the arm 40 to rotate relative to the arm 30. The tabs 34 and 36 include an axial locking pin aperture 62. The protrusion 42 includes a series of locking pin apertures 64. The example embodiments shown in the attached figures include five rotational locking pin apertures 64 arranged in a semicircle about the protrusion 42. Those of skill in the art will appreciate that the number, orientation, and spacing of the rotational locking pin apertures 64 can be varied to provide various degrees movement of the support arm 40 relative to the hitch arm 30e.g., more or less than 180 degrees of movement and movement through various increments or rotation.

[0030] The axial locking pin aperture 62 and one of the rotational locking pin apertures 64 are aligned and a rotational locking pin 66 is inserted therethrough to fix the orientation of the arm 40, and thus the umbrella 20, relative to the arm 30 so that the umbrella 20 can be positioned at different orientations. The rotational locking pin 66 and the axel pin 60 can be cotter pins that utilize a separate clip that extends through the pin to hold the pin within the axle pin aperture 54 or the rotational locking pin apertures 64. In other embodiments, the rotational locking pin 66 and the axel pin 60 can be spring-loaded pins that include a spring-loaded ball bearing disposed within the pin that extends outward from the pin to lock the pin in place when the pin is disposed within an aperture.

[0031] FIGS. 6-7 illustrate dimensions for an example embodiment of the knuckle 32, which is formed from the protrusion 42 and the tabs 34 and 36. The outer dimensions of the knuckle components 32 are the same or smaller than the outer dimensions of the tubular hitch arm 30 and the support arm 40 so that both arms 30 and 40 and can fit within the hitch tube 14. This allows either component to be stowed in the hitch tube 14 when not in use, and it allows the hitch arm 30 to be removed and the support arm 40 to be directly inserted into the hitch tube 14 to shorten the length of the assembly 18 such that the umbrella is closer to the vehicle 10. In such a configuration, the hitch pin 16 can be inserted through the hitch pin apertures 44 to secure the support arm 40 to the vehicle hitch 12.

[0032] In one non-limiting embodiment, the arms 30 and 40 and the support arm 46 are made of aluminum. The components of the assembly 18 can be coated with a corrosion resistant coating to enhanced durability.

[0033] The foregoing discussion discloses and describes merely exemplary embodiments of the present disclosure. One skilled in the art will readily recognize from such discussion and from the accompanying drawings and claims that various changes, modifications and variations can be made therein without departing from the spirit and scope of the disclosure as defined in the following claims.
