Exercise machine with device for handling on wheels

Abstract

The present industrial invention refers to an exercise machine provided with a device for handling on wheels mounted under the machine platform and comprising a wheel supported at the end of an arm that oscillates freely on the vertical plane, which spontaneously tends to descend and remain in lowered position by means of a retention mechanism actuated by a spring and deactivated by a pedal.

1 . Exercise machine with device for handling on wheels, of the type comprising at least a ground platform ( 2 ) provided with front and back feet ( 3 ) and wheels ( 4 ) with fixed axis located next to the front edge of the platform ( 2 ) before the feet ( 3 ), having a suitable height to prevent the wheels ( 4 ) from touching the ground, machine ( 1 ) characterised by the fact that it is equipped with at least one device ( 6 ) mounted under the platform ( 2 ) in opposite position with respect to the wheels ( 4 ), which comprises a wheel ( 7 ) supported at the end of an arm ( 8 ) that oscillates freely on a vertical plane, spontaneously tends to descend and is blocked in lowered position by means of a retention mechanism ( 10 ,  10   a ) actuated by a return spring ( 11 ) and deactivated by means of a pedal ( 12 ) pivoted onto the platform ( 2 ); it being provided that when the retention mechanism is activated, the machine ( 1 ) is raised from the ground and tilted forward so that the feet ( 3 ) lose contact with the ground and the wheels ( 4  and  7 ) touch the ground.  
   
   
       2 . Machine as defined in  claim 1 , characterised by the fact that the arm ( 8 ) has a shelf-like configuration with a central lowered housing ( 8   a ) and a lateral transversal ramp ( 8   b ) immediately before the housing ( 8   a ); with the ramp ( 8   b ) and the housing ( 8   a ) acting as slide and stop for a bearing ( 10   a ) supported at the end of a rod ( 10 ) which is provided at the other end with a collar ( 10   b ) for pivoting at a bearing pin with vertical axis fixed to the platform ( 2 ), in such a way that the rod ( 10 ) freely oscillates on the horizontal plane under the platform ( 2 ); it being provided that the rod ( 10 ) is constantly subject to the action of the return spring ( 11 ), which tends to raise the bearing ( 10   a ) onto the ramp ( 8   b ) until it engages inside the housing ( 8   a ).  
   
   
       3 . Machine as defined in  claim 2 , characterised by the fact that the device ( 6 ) also comprises a pedal ( 12 ) pivoted onto the platform ( 2 ) and connected by means of a connecting rod ( 13 ) to a cylindrical support ( 14 ) in contrast with the rod ( 10 ), which slides inside a support and guide bush ( 15 ) fixed under the platform ( 2 ) with longitudinal axis in horizontal position perpendicular the axis of the arm ( 8 ).  
   
   
       4 . Machine as defined in  claim 1 , characterised by the fact that the wheel ( 7 ) is a pivot wheel.
