Abstract

A golf course simulator comprises a track running between a driving area and a target. The track incorporates a plurality of selectively openable and closable holes. The target marks the boundary between the virtual space in which an objective hole is situated in a first phase of the game, when the strokes played are swings, and a real space in which the objective hole is materialized by opening one hole, once the player has come close enough to the objective hole. The simulator is controlled by an appropriately programmed computer. For swings the driving area incorporates a ball sensor and the target incorporates an impact detector matrix. Measuring the time between the departure of the ball and the impact on the target, at a known distance, and location of the point of impact on the target supply initial speed, lift and drift information to determine the point of arrival of the ball in the virtual space and to deduce therefrom objective parameters. If the objective hole is in the real space one hole is opened and the length of the putt as determined by sensors arranged along the track results in the opening of another hole corresponding to the distance for the remaining putt or putts.

Claims

1. A golfcource simulator device comprising a series of holes into which a player must direct a ball in corresponding successive stages in each of which one hole constitutes a stage of objective to which the ball advances from a start area, the player playing all his strokes from the same point and the progress of the ball along the course being simulated by displacement of the objective hole according to parameters of the preceding stroke, said device comprising a driving area, a first ball sensor in said driving area, an elongated track extending from said driving area, a plurality of selectively openable and closable holes on said track, a plurality of second ball sensors each associated with a respective hole, a plurality of third ball sensors disposed along the length of said track to determine the farthest position reached by a ball on said track after a stroke, a target closing said track sat the end opposite said driving area and separating a real space between it and said driving area and a virtual space on the side of said target opposite said driving area, a plurality of impact sensors on said target and control means including a programmed computer comprising means;

defining the series of stages each corresponding to a field extending from a start area to an objective hole and subdivided into an ordered plurality of contiguous cells memorized in said computer in the form of a file comprising plurality of blocks of information each associated with a respective one of said cells of said field and each containing data for identifying the associated cell relative to the start area and the objective hole for the stage in question;

determining stroke parameters either from conditions of impact on said target or from the position of the ball on said track after the stroke according to whether the objective hole for the cell in which the origin of the stroke is simulated is in said virtual space or in said real space, respectively;

determining the cell of said field in which the ball is located after a stroke from the stroke parameters and the cell reached after the preceding stroke;

retrieving from said file objective parameters associated with the cell reached after the preceding stroke, which parameters condition the opening of a particular hole on said track if said cell is in said real space; and

registering the end of a stage in response to activation of one of said second ball sensors corresponding to entry of the ball into the opened hole.

2. The device according to claim 1 comprising an image synthesizer connected to said computer and defining means to produce a synthesized image on said target, each information block in said file which is associated with a cell of the stage field for which the objective hole is in said virtual space comprising data on the basis of which said synthesizer synthesizes a schematic panoramic view of the stage field as seen from the associated cell looking towards the objective hole.

3. The device according to claim 2 wherein said information blocks further comprise objective information displayable in alphanumeric form on said target.

4. The device according to claim 1 wherein said driving area comprises a plurality of stroke start areas each simulating a respective type of terrain and exposable individually in response to specific data in the information block associated with the stage field in which the ball is located after the previous stroke.

5. The device according to claim 4 wherein said first ball sensor comprises at each stroke start area a respective photo-electric device disposed below an orifice defining a ball support whereby placing a ball on said support cuts off illumination of said photo-electric device.

6. The device according to claim 1 wherein said driving area comprises at least one tiltable ground panel on which the player stands to play a stroke and means for controlling the inclination of said at least one tiltable ground panel according to specific data in the information block associated with the stage field in which the ball is situated after the preceding stroke.

7. The device according to claim 6 wherein said driving area comprises two tiltable ground panels in conjugate positions to either side of a longitudinal axis passing through the stroke start areas.

8. The device according to claim 1 wherein said track is tiltable according to commands received from said control means.

9. The device according to claim 8 wherein said track is tiltable longitudinally.

10. The device according to claim 8 wherein said track is tiltable transversely.

11. The device according to claim 10 wherein said track is tiltably mounted transversely to a degree sufficient to cause a ball to roll down the resulting transverse slope and further comprising a longitudinal gully running alongside said track to receive a ball after it has rolled down said transverse slope, returning a received ball to said driving area and equipped with third ball sensors which are disposed along the length of said gully.

12. The device according to claim 1 comprising a control device connected to said plurality of selectively openable and closable holes openable only one at a time according to commands received from said control means.

13. The device according to claim 12 wherein each hole comprises a tubular wall in the shape of a sector of torus with a centerline in a plane perpendicular to the surface of said track and a closure member movable along said line between a lowered open position and a raised closed position.
