Apparatus for motorcycle polo game
BACKGROUND OF THE INVENTION 
     1. Field of the Invention. 
     This is a continuation-in-part of my original application for patent, Ser. No. 577,305 filed June 9, 1975 now co-pending and which is to be abandoned upon the filing of this specification. 
    
    
     The invention relates generally to the game of polo, and more particularly to apparatus for motorcycle polo game. 
     2. Description of the Prior Art. 
     Polo does not seem to have been played on motorcycles heretofore, but has been played on bicycles with no modification of the bicycle or field. 
     SUMMARY OF THE INVENTION 
     It is an object of the invention to provide steering apparatus that will not interfere with hitting a ball with a mallet from a motorcycle. 
     Another object of the invention is to provide foot control for all motor controls and braking. 
     Another object of the invention is to increase traction and decrease wear and tear on a playing field. 
     A further object of the invention is to provide apparatus for stabilizing a rider on a moving motorcycle as he rises from his seat and tries to hit a ball on the ground. 
     A last object of the invention is to provide side boards and goals on the field that are compatible with the use of motorcycles.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIG. 1, the invention comprises a motorcycle 10 of any convenient make and size which is modified by installing wide anti-skid tires 12 on disc wheels 14 and removing the conventional handlebars (not shown) and replacing them with steering control 16 that is rigidly connected to a central steering post 18. Resilient knee rolls 20 are adjustably mounted to a circumferential strap 22 for securing around a top mounted gas tank 24, the rolls being adjusted adjacent the knees of a rider or player to permit him to lean forward and backward without fear of loosing his knee grip on motorcycle 10. A hand strap 26 secured to center steering post 18 at one of said strap ends and to strap 22 at the other of said ends defines a hand loop 30 at the strap 22 end for engaging with a steering hand gripping operably steering control 16 for preventing inadvertently changing direction of motorcycle 10 when leaning outward to strike a ball. See FIG. 4. 
     Conventional foot controls are modified by adding foot-cups 32 to pedal controls 34 and 36 of motorcycle 10. A foot-cup 32 is fixed to pedal control 34 to which brake cables 38 and 40 are operably connected for brake application when pedal control 34 is depressed, and throttle cable 42 is connected for increasing speed when pedal control 34 is raised. A second foot-cup 32 is slidably mounted on pedal control 36 and biased by spring 44 rearward. Second foot-cup 32 is connected with clutch cable 46 for disengaging the clutch when slid forward and engaging said clutch (not shown) when biased rearward. Raising and depressing pedal control 36 shifts gears. See FIGS. 9-12. 
     A polo playing field is modified by covering with a neoprene covered netting 48 that is secured to the field on three foot centers by staples 50. Side boards 52 running along the sides of the field are pivoted to anchoring extensions 54 and biased upright for deflecting a ball back in the field but allowing a motorcycle 10 to flatten it in either direction of pivoting when running into it. Goal posts 56 are made of an elastic material for yielding to impact with a motorcycle 10. The field modifications thus permit fast stops, starts and turns without destroying the turf and with increased traction between wide non-skid tires and the field, allows collisions with side boards without damage to motorcycle and rider, and the same with respect to goal posts. See FIGS. 5-8. 
     Referring to FIGS. 2 and 3, steering control 16 comprises clamps 58 rigidly clamping it to center steering post 18. Miniature handlebars 60 with hand knobs 62 are connected by transverse rod 64 serving as a pivot support for a rearwardly extending steering lever 68 on the end of which handgrip 70 is fixed. Handlebars 60 are provided to meet the minimum requirements for road use to get motorcycle 10 to and from a playing field under its own power. 
     Steering lever 68 comprises a deformable middle sleeve 72 pivoted at one end to transverse rod 64 equi-distant from said hand knobs 62. Interior &#34;I&#34; channel 74 is defined in the top of middle sleeve 72 with the parallel end channel parts 76 defining semi-circles adjacent the oppositely disposed ends of middle sleeve 72. An inner member 78 having an upwardly projecting lug or cam 80 adapted to engage in &#34;I&#34; channel 74 is forced into middle sleeve 72 by deforming it sufficiently to admit lug or cam 80 past the free end of middle sleeve 72 and slidably engage said inner member 78 in said middle sleeve 72 with lug 80 engaged in &#34;I&#34; channel 74. A non-deformable outer sleeve 82 is fixed around deformable middle sleeve 72 to prevent any deformation that would allow the disengagement of lug 80 from channel 74. Handgrip 70 is mounted normal to inner member 78 and on its free end to extend upwardly.
