Golf platform with adjustable inclination

Abstract

The present invention provides a golf practicing device having a platform with adjustable tilt on two independent axial creating a variety of inclination thus allowing a player to simulate variety of lies of the golf course in a driving range. In its first embodiment, the device comprising of a hitting surface 20 covered with artificial turf 21, mounted on a base 10 with a double-cross joint 30. On the hitting surfaces 20 are switches 70 a 70 b 70 c 70 d wired to a pair of linear actuators 50 51 affixed to a cable 80 running through a conjugated pulley cable guide 40 41 42 43 so that pressing the switches 70 a 70 b 70 c 70 d will cause one side of the hitting surface 20 to lower and the opposite side to lift up, causing the golf platform to tilt toward the direction of activated switch.

       21 . golf practicing device, more specifically a golf practicing platform, comprising of:
 a) a base structure,   b) a hitting surface,   c) a universal pivot with its lower set of support connectors connected to the base structure, and the top set of the support connectors connected to the hitting surface, such that the center of the base structure and the center of the hitting surface align, and hitting surface can pitch and roll relative the base structure,   d) four pulley assemblies, mounted in a square array and equidistance from the center of the base structure, each set of the pulley assemblies comprising of
 i. a lower pulley mounted on base structure so the axis of the said pulley is aligned pointing to the center of the device, 
 ii. a left upper pulley mounted under the hitting surface so one of its grooves is directly above of and aligns with the left groove of the lower pulley in the assembly, such that the axis of the said left upper pulleyis 45 degrees clockwise from the said lower pulley, 
 iii. a left upper pulley mounted under the hitting surface so one of its grooves is directly above of and aligns with the left groove of the lower pulley in the assembly, such that the axis of the said left upper pulley is 45 degrees counter-clockwise from the said lower pulley, 
   e) a loop of wire, first guided through the first pulley assembly; then guided through a second pulley assembly to the right of the first pulley assembly; then a third pulley assembly to the right of the second pulley assembly; and finally a fourth pulley assembly which is to the right of the third pulley assembly and the left of the first pulley assembly, the wire is guided through each of the pulley assemblies by first being guided through the left upper pulley of that assembly, then the lower pulley of that assembly, finally the right upper pulley of that assembly, the wire is also fasted to the underside of the hitting surface at a point betwccn two pulley assemblies,   f) a pair of linear actuators mounted under the hitting surface parallel to the direction of the wire, with the clevis of each of the said actuators fastened to the wire,   g) a set of switches connected electrically to the actuators so the switches control the extension and retraction of the actuators   
   
   
       22 . golf practicing device as claimed in  claim 21 , where the set of switches comprising of four switches mounted in a rectangular array on the upper surface of the hitting surface and connected to the actuators so that activating each switch will cause the actuator to actuate the wire and cause the hitting surface to pitch toward the direction of the activated switch. 
   
   
       23 . A golf practicing device as claimed in  claim 21 , where the set of switches comprising of four switches mounted in a rectangular array on the upper surface of the hitting surface and connected to the actuators so that activating each switch will cause the actuator to actuate the wire and force the hitting surface to pitch to the direction opposite of the activated switch.
