Leisure equipment with wheeled vehicle

Abstract

Leisure equipment is disclosed which permits an experience of fully controlled loop-the-loop rotary motion with a wheeled vehicle. The leisure equipment comprises a frame structure with a trough-shaped wheel track, an axis of rotation and at least one rotating arm with one wheeled vehicle each. The trough-shaped wheel track is curved so as to form a closed contour. The axis of rotation is contained within this contour. At least one rotating arm is rotatably supported on this axis of rotation. At the rotating arm a wheeled vehicle is fastened which is adapted to be guided in the wheel track. The wheeled vehicle is pressed into the wheel track by a pressing device acting on the rotating arm. In this way a contact of wheel track and wheeled vehicle exists in every point of the wheel track. With the wheeled vehicle of the leisure equipment, a rider can perform loop-the-loop rotary motions or revolutions during which he retains full command of the motion at all times.

What is claimed is:

 a trough-shaped wheel track ( 110 ,  120 ) curved so as to form a closed contour,    an axis of rotation ( 210 ) supported within the contour of the wheel track,    at least one rotating arm ( 200 ) supported rotatably on the axis of rotation ( 210 ), and    at least one wheeled vehicle ( 300 ) fastened at one end of the rotating arm ( 200 ) and adapted to be guided in the wheel track,    wherein a pressing device ( 320 ,  330 ) acting on the wheeled vehicle ( 300 ) is provided which presses the wheeled vehicle ( 300 ) into the wheel track ( 110 ,  120 ).    
     
     
         2 . Leisure equipment according to    claim 1    where the pressing device has a pneumatic spring ( 320 ,  330 ).  
     
     
         3 . Leisure equipment according to    claim 1    where the pressing device has a helical spring.  
     
     
         4 . Leisure equipment according to    claim 1    where the pressing device has a leaf spring.  
     
     
         5 . Leisure equipment according to one of the preceding claims where the contour of the wheel track ( 110 ,  120 ) is circular and the axis of rotation ( 210 ) is situated in the center of the circle.  
     
     
         6 . Leisure equipment according to one of the preceding claims where the wheeled vehicle ( 300 ) is detachably connected with the rotating arm ( 200 ).  
     
     
         7 . Leisure equpiment according to one of the preceding claims where the wheeled vehicle ( 300 ) is solidly connected with the rotating arm ( 200 ).  
     
     
         8 . Leisure equipment according to one of the preceding claims where at the free end of the rotating arm ( 200 ) opposite to the wheeled vehicle ( 300 ) at least one weight can be fastened (at  270 ), and the position of the weight along the rotating arm ( 200 ) is adjustable.  
     
     
         9 . Leisure equipment according to one of the preceding claims where the wheeled vehicle ( 300 ) has a bicycle.  
     
     
         10 . Leisure equipment according to    claim 9    where a free wheel is provided both forward and backward when the pedals are not treaded.  
     
     
         11 . Leisure equipment according to    claim 9    where the bicycle has a saddle ( 340 ) adjustable in its height.  
     
     
         12 . Leisure equipment according to one of the preceding claims where the rotating arm ( 200 ) can be decelerated by a braking system operable from outside.  
     
     
         13 . Leisure equipment according to    claim 12    where a disk break is used as the braking system in the axis of rotation ( 210 ).  
     
     
         14 . Leisure equipment according to    claim 12    where a drum brake is used as the braking system in the axis of rotation ( 210 ).  
     
     
         15 . Leisure equipment according to one of the preceding claims where appropriate harness to secure the rider is attached to the rotating arm ( 200 ).
