Abstract
A combined skateboard and ski which includes a body board having two bottom riser pads, a ski, and cushions. Lock nuts and two mounting frames are provided on a top side of the ski for securing the ski to the riser pads of the body board. Each of the mounting frames has a support arm and a pivot hole formed in the support arm. Two wheel assemblies are fastened to the riser pads of the body board by cushions and lock nuts to form a skateboard after removal of the mounting frames from the riser pads.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a skateboard and ski arrangement, which enables a skateboard to be detachably fastened to a ski for sliding over snow.




2. Description of the Related Art




A regular ski, as shown in

FIGS. 6 and 7

, comprises a skiing board


3


, a footplate


4


, and two mounting structures


5


that connect the footplate


4


to the skiing board


3


. Each mounting structure


5


comprises a first mounting frame


51


fixedly provided at the bottom side of the footplate


4


, a second mounting frame


52


fixedly provided at the top side of the skiing board


3


, and a pivot bolt


53


adapted to secure the first mounting frame


51

52


. The ski can simply be used for sliding over snow. For skating over a hard smooth surface, a skateboard may be used. It is expensive to prepare a skateboard and a ski for different purposes. Further, it requires much storage space to keep a skateboard and a ski when not in use.




SUMMARY OF THE INVENTION




The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a skateboard and ski arrangement, which enables the user to use the skateboard for skating over a hard smooth surface, or to fasten the skateboard to a ski for sliding over snow. According to the present invention, the skateboard and ski arrangement comprises a board body having two bottom riser pads, a ski, cushions and lock nuts two mounting frames fixedly provided at a top side of the ski and adapted for securing the ski to the riser pads of the board body by the cushions and the lock nuts, said mounting frames each comprising a support arm, a pivot hole disposed in said support arm and adapted for receiving the threaded pivot of one riser pad of said board body, and two wheel assemblies adapted for fastening to the riser pads of the board body by the cushions and the lock nuts to form with the board body a skateboard after removal of the mounting frames from the riser pads.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to FIGS. from


1


through


5


, a ski


1


is showing having two mounting frames


11


(only one pivot holder is shown in the drawings). Each mounting frame


11


comprises an angled support arm


111


vertically extended upwards and then turned sideways in horizontal direction, a pivot hole


112


in the horizontal upper part of the support arm


111


, and a locating rod


114


extended from the horizontal upper part of the support arm


111


. The skateboard, referenced by


2


, comprises a board body


23


, two riser pads


21


fixedly provided at the bottom side of the board body


23


(only one riser pad is shown in the drawings). Each riser pad


21


comprises a locating hole


211


and a threaded pivot


213


for the mounting of one mounting frame


11


of the ski


1


or a wheel assembly


22


selectively. The wheel assembly


22


comprises a wheel holder


221


holding two wheels


224


at two sides, a pivot hole


222


in the wheel holder


221


between the wheels


224


, and a locating rod


223


extended from a middle part of the wheel holder


221


.




The mounting frame


11


can be fastened to the corresponding riser pad


21


of the board body


23


by: inserting the threaded pivot


213


of the riser pad


21


through the pivot hole


112


and the locating rod


114


into the locating hole


211


, and then threading a lock nut


215


onto the threaded pivot


213


to fix the threaded pivot


213


to the mounting frame


11


. Further, cushions


214


are respectively mounted on the threaded pivot


213


and secured between the riser


21


and the lock nut


215


at two sides of the support arm


111


of the mounting frame


11


. Because the horizontal upper part of the support arm


111


is suspended above the base of the mounting frame


11


by a gap


113


, the user can conveniently insert a wrench into the gap


113


to fasten up or loose the lock nut


215


. The connection of the wheel assembly


22


to the riser pad


21


is also easy. By inserting the threaded pivot


213


through the cushions


214


and the pivot hole


222


and the locating rod


223


into the locating hole


211


and then fastening the lock nut


215


to the threaded pivot


213


, the wheel assembly


22


is fastened to the riser pad


21


.




The user can selectively fasten two wheel assemblies


22


or the mounting frames


11


of the ski


1


to the riser pads


21


of the board body


23


. When two wheel assemblies


22


fastened to the riser pads


21


of the board body


23


, the board body


23


and the wheel assemblies


22


form a skateboard for skating. When the mounting frames


11


of the ski


1


fastened to the riser pads


21


of the board body


23


, the user can stand on the board body


23


to slide over snow.




Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
