DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a driving device for golf practice, particularly for so-called driving ranges, and the device comprises a platform having a suitable upper surface for carrying a golf ball, for example a carpet, and the platform can be inclined in any desired direction.
An essential aspect of the everyday life of a golf player is the systematic training which often takes place in connection with a practice field, so-called driving range. At such practice field there are usually at one end thereof lined up so-called driving carpets, from which the golf players make their drives. However, in play under realistic conditions on a golf course quite varying playing conditions are encountered in that the ball has to be played in upward slpe, downward slope and the like, which calls for special techniques. Today's practice fields for golf play are therefore incomplete in that at the conventional driving sites one cannot simulate the situations arising in real play out on the course.
Therefore, the present invention has for its purpose to provide a driving device wherein the play platform can be adjusted to incline in different directions. Another purpose of the invention is to provide such driving device wherein the driving support or platform can be oriented in the desired direction in a simple manner and without exertion of large forces.
SUMMARY OF THE INVENTION
Starting from a driving device having an inclined platform there is according to the invention for these and other objects provided a construction which below the platform is provided with a centrally positioned downwardly directed pillar which is vertically displaceable and rotatably arranged in a guide member or tube which is fixed part of a fixture or plate intended to rest on the ground or other support. Moreover, the device is provided with support means by which stability is imparted to the platform when in a lowered position. Finally, the device according to the invention is provided with lifting means by which the platform can be raised to an upper position and rotated thereat to the desired orientation and then again lowered to a stable lowered position. The driving device is then ready for use in golf training.
In a preferred embodiment of the driving device according to the invention the lifting means comprise an outwardly and downwardly pivotable lifting member, the outward movement of which imparts raising of the platform so that the pillar moves upwardly in the tube, a locking member being provided to hold the pillar and thus the platform in its upper position.
According to another preferred feature of the device of the invention a horizontal manoeuvring axle is arranged at the lower side of the platform which carries lifting member and the rotation of which imparts raising or lowering of the said lower side. Said lifting member is preferably arranged to be operated by means of a control stick positioned at one side of the platform.
Moreover, the driving device of the invention may comprise at least one retractable support member arranged at the lower side of the platform. The manoeuvring axle is preferably provided with members which are arranged to move the support member to its outward position when the lifting member is moved outwardly. It is furthermore preferred that the driving device of the invention comprises means for returning the support member to retracted position on returning the lifting member.
