Title: Snow ski-bike

Description:
BRIEF DESCRIPTION OF DRAWINGS  
     A preferred embodiment of the present invention will now be described with reference to the accompanying drawings in which: 
       FIG. 1  is a perspective view of The Snow Ski-Bike constructed in accordance with the present invention. It should be noted at this time, that the front fork suspension is interchangeable with any of the current manufacturer&#39;s designs already in use. In this perspective view, all components and mounting hardware are connected giving the observer a seemingly mental picture of how all the parts function together. 
       FIG. 2  is a perspective view of the typical ski bottom equipped with dual traction fins. The braking system cannot be seen in this drawing, but is featured in the previous figure. The front and rear brakes are positioned on the top-side rear-most section of the ski. 
       FIG. 3  is a segmented view showing the embodiment of the construction of both the swing arm and rear shock assembly and its connection to the ski pivot shock assembly which eventually mounts to the rear ski.

     DESCRIPTION  
       FIG. 1  shows The Snow Ski-Bike ( 10 ), according to the possible embodiment of the present invention. The Snow Ski-Bike ( 10 ) comprises a mainframe ( 12 ), which may be as illustrated, substantially similar to a conventional bicycle frame. The mainframe ( 12 ), has a down tube ( 14 ), a top tube ( 13 ), a seat tube ( 16 ), for supporting a seat ( 20 ), a front head tube ( 30 ), a bottom bracket ( 21 ), with foot holders ( 22 ), and foam rubber safety pad ( 24 ). Mounted on the top tube ( 13 ), the seat ( 20 ), has an alternate seat tube ( 18 ), and is adjustable which will add virtual length to the top tube ( 13 ). 
     The Snow Ski-Bike ( 10 ) is called as such because it is primarily designed for the winter season. It should be noted at this time that this particular embodiment of The Snow Ski-Bike does not contain a form of propulsion as it is designed to be carried to the top of the mountain by the ski lift. 
     The front of the main frame ( 12 ) is supported by a steer able assembly that is operatively connected to the head tube ( 30 ). This assembly is actuated by the user through the handle bars ( 34 ). It consists of a front suspension fork ( 32 ), and detachable ski pivot assembly ( 46 ), with ski ( 56 ). The ski ( 56 ), will return to the true horizontal position when hitting an obstacle on the terrain at the moment the horizontal leveler shock ( 50 ), is engaged and cycles through its rebound phase. 
       FIG. 2  The ski assemblies ( 46  &amp;  56 ), are removable/connected to both the front and rear suspensions of the main frame ( 12 ), easing the storage or the transportation or The Snow Ski-Bike ( 10 ). 
     Each of the ski assemblies as shown in  FIGS. 1 and 2  comprises a set of traction fins and a brake assembly. 
       FIG. 3  The rear suspension shock assembly ( 42 ), comprises of a pivoted double swing arm ( 38 ), which is operatively connected to the main frame ( 12 ). The shock is mounted between the swing arm assembly ( 38 ), and the rear most portion of the main frame ( 12 ). 
     A ski ( 56 ), and ski pivot assembly ( 46 ), which is nearly identical to assembly used in conjunction with the front suspension are also removable/connected for ease of storage and transportation. 
     Although a preferred embodiment of The Snow Ski-Bike, has been described in basic detail herein and illustrated in the accompanying drawings, it should be understood that The Snow Ski-Bike, is not limited to this precise embodiment and that various changes and modifications may be effected therein without departing from the scope or spirit of the present invention.
