Abstract:
A vehicle external device attachment system that allows users to attach devices such as heaters or fans to their uncovered vehicles. An example of such a vehicle is a golf cart. The height of the attached device is adjustable via an adaptor ring. The vehicle external device attachment system provides stability to the external devices unprecedented in existing systems.

Description:
BACKGROUND OF THE INVENTION 
     Harsh weather conditions make driving a golf cart unenjoyable. Although propane heaters and electric fans tailored for golf carts do exist, they typically only fit in the golf cart cup holders. Inevitably, this takes away from the number of cup holders available for beverages. This also prevents users from easily adjusting the propane heaters and electric fans to a desired height. Furthermore, when such cup holders are installed at the ends of the golf cart dash, the propane heaters and electric fans hinder users from entering and exiting the golf cart. 
     Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     The present invention is a vehicle external device attachment system ( 100 ) onto which an external device ( 600 ) can be attached. The vehicle external device attachment system ( 100 ) is easily adjustable to the desired height and saves any existing space within a vehicle ( 500 ) (for example, space of cup holders and space to enter and exit the vehicle ( 500 )) from being used. In some embodiments, the vehicle ( 500 ) is a golf cart. 
     Referring now to  FIG. 1 , the vehicle external device attachment system ( 100 ) comprising a hollow base cylinder ( 200 ) is shown. The base cylinder ( 200 ) has a base cylinder first end ( 210 ) and a base cylinder second end ( 220 ). In some embodiments, a base cylinder plate ( 230 ) is disposed on the base cylinder first end ( 210 ). In some embodiments, a plurality of base cylinder plate attachment holes ( 235 ) are disposed on the base cylinder plate ( 230 ). In some embodiments, a base cylinder insert ( 240 ) is partially disposed closer to the base cylinder second end ( 220 ) and through the surface of the base cylinder ( 200 ) in the diametric direction. In some embodiments, the base cylinder insert ( 240 ) is a screw. 
     Referring again to  FIG. 1 , the vehicle external device attachment system ( 100 ) comprising a hollow main cylinder ( 300 ) is shown. The main cylinder ( 300 ) has a main cylinder first end ( 310 ) and a main cylinder second end ( 320 ). In some embodiments, the main cylinder first end ( 310 ) diameter is smaller than the main cylinder second end ( 320 ) diameter and the base cylinder ( 200 ) diameter. This allows the main cylinder first end ( 310 ) to insert through the base cylinder second end ( 220 ). In some embodiments, the main cylinder second end ( 320 ) diameter is bigger than the base cylinder ( 200 ) diameter. This prevents the entire main cylinder ( 300 ) from sliding through the base cylinder ( 200 ). 
     In some embodiments, a main cylinder insert ( 330 ) is partially disposed closer to the main cylinder second end ( 310 ) and through the surface of the main cylinder ( 300 ) in the diametric direction. In some embodiments, the main cylinder insert ( 330 ) is a screw. In some embodiments, a main cylinder bracket ( 340 ) is disposed closer to the main cylinder second end ( 320 ) and on the surface of the main cylinder ( 300 ). In some embodiments, a plurality of main cylinder bracket attachment holes ( 345 ) are disposed on the main cylinder bracket ( 340 ). 
     In a non-limiting example, the assembly of the vehicle external device attachment system ( 100 ) is as follows: the base cylinder plate ( 230 ) attaches to a vehicle floor ( 510 ) via the plurality of base cylinder plate attachment holes ( 235 ) with fasteners including but not limited to screws, bolts, or rivets. In some embodiments, the base cylinder plate ( 230 ) is attached to the center of the vehicle floor ( 510 ). The plurality of base cylinder plate attachment holes ( 235 ) allow installation flexibility, as fasteners can be disposed wherever most appropriate to adequately secure the base cylinder plate ( 230 ). 
     Continuing with the non-limiting example, the main cylinder first end ( 310 ) then inserts through the base cylinder second end ( 220 ). The main cylinder first end ( 310 ) is secured to the base cylinder second end ( 220 ) by tightening the base cylinder insert ( 240 ) against the surface of the main cylinder ( 300 ). The main cylinder ( 300 ) is secured to a vehicle front ( 520 ) via the plurality of main cylinder bracket attachment holes ( 345 ) with fasteners including but not limited to screws, bolts, or rivets. In some embodiments, the vehicle front ( 520 ) is the vehicle dash. The plurality of main cylinder bracket attachment holes ( 345 ) allow installation flexibility, as fasteners can be disposed wherever most appropriate to adequately secure the main cylinder ( 300 ). 
     In some embodiments, as an option, an elbow cylinder ( 700 ) having an elbow cylinder first end ( 710 ) and an elbow second end ( 720 ) is used to connect the main cylinder ( 300 ) and the base cylinder ( 200 ). Referring to  FIG. 7 , the elbow cylinder ( 700 ) connected to the base cylinder ( 200 ) is shown. That is to say, the base cylinder plate ( 230 ) attaches to the vehicle front ( 520 ) via the plurality of base cylinder plate attachment holes ( 235 ). The base cylinder second end ( 220 ) inserts through the elbow cylinder first end ( 710 ) and the main cylinder first end ( 310 ) inserts through the elbow cylinder second end ( 720 ). The main cylinder first end ( 310 ) is secured to the elbow cylinder second end ( 720 ) via compression fit and the base cylinder second end ( 220 ) is secured to the elbow cylinder first end ( 710 ) also via compression fit. The main cylinder ( 300 ) is then secured to the vehicle front ( 520 ) via the plurality of main cylinder bracket attachment holes ( 345 ). Referring to  FIG. 8 , the base cylinder ( 200 ) and the main cylinder ( 300 ) both attached to the vehicle front ( 520 ) is shown. 
     Referring to  FIG. 2 , the assembly of just the base cylinder ( 200 ) and the main cylinder ( 300 ) is shown. Referring to  FIG. 3 , the assembly of just the base cylinder ( 200 ) and the main cylinder ( 300 ) with the main cylinder bracket ( 400 ) in view is shown. Referring to  FIG. 5 , the assembly of the vehicle external device attachment system ( 100 ) is shown. Without wishing to limit the present invention to any theory or mechanism, it is believed that mounting the vehicle external device attachment system ( 100 ) at two locations (the vehicle floor ( 510 ) and the vehicle front ( 520 ) or, if using the elbow cylinder ( 700 ) option, the vehicle front ( 520 ) twice) provides stability to the vehicle external device attachment system ( 100 ) unprecedented in existing systems. 
     Referring to  FIG. 4 , examples of an adaptor ring ( 400 ) having a bigger diameter than the main cylinder first end ( 310 ) is shown. The adaptor ring ( 400 ) inserts through the main cylinder second end ( 320 ), followed by an external device ( 600 ) inserting through the main cylinder second end ( 320 ). The external device includes but is not limited to a propane heater or an electrical fan. The external device ( 600 ) thus rests on the adaptor ring ( 400 ). The height of the external device ( 600 ) is adjusted by the adaptor ring ( 400 ) by adjusting the size of the adaptor ring ( 400 ). Finally, the external device ( 600 ) is secured to the main cylinder ( 300 ) by tightening the main cylinder insert ( 330 ) against the surface of the external device ( 600 ). Referring to  FIG. 6 , an example of an external device ( 600 ) attached to the vehicle external device attachment system ( 100 ) is shown.
