FR2703914A1 - Golf mat with variable tilting - Google Patents

Abstract

The invention relates to a training mat with variable tilting, for playing golf, in order to reproduce, when practising, the conditions of an uneven and sloping course (terrain). It consists of a base (1) surmounted by a sloping surface (2) which the golfer can orient as he wishes with respect to a target. This has the effect of changing the slope of the surface (2) with respect to the target. The height (H) can vary so as to resemble the slope of the course to be played. The surface (2) is covered with at least one element (3) serving to prevent the ball from rolling despite the slope and also for striking the ball under natural conditions. The base (1) and the plate (2) can be actuated in terms of rotation and may have automatic functions.

Description

 The present invention relates to a training mat with variable inclinations for the golf course, in order to reproduce in training the conditions of uneven and sloping terrain.

 Golf training is usually done on a square mat, about 1.5m square, flat and horizontal, made of rubber, in which is encased a rectangular mat of about 0.40x0.60m.

 The player stands on the rubber part, places his ball on the mat, then hits it with his club towards the target.

 This is a training for learning the golf swing movement. The training conditions described above do not reproduce the game situations encountered on uneven or sloping terrain.

The devices according to the invention make it possible to remedy this in 4, cpnvénient .-
The variable inclination golf mat of the type described below does not involve any mechanical element in its design for reasons of reliability and cost ~
It is a cylinder about 1.5 m in diameter, truncated at a certain angle of inclination, and the truncated surface of which is covered with a pail-classon in the shape of a crown on its periphery. cylinder allows to modify the inclination compared to the target.

 the drawings fig 1 and fig 2 illustrate the invention in space. It is the same golf mat in two opposite positions. Only the covering of the surface by the mat changes. in fig 1 for the sake of simplifying the crown-shaped doormat is replaced by four small standard-shaped doormats, which still offers the player four playing positions.

 With reference to the drawings in fig 1 and fig 2 the device comprises a cylinder.

-dre truncated (1) of about 1.5m in diameter provided with handles (8) of an inclined surface (2) covered with rubber. With a doormat in the shape of a crown fig 2. Or else four doormats: One on the lowest part of the inclined surface (2), one on the highest part of the inclined surface (2), two on the middle part fig 1.

 The mat (3) is of a different design from those already existing because it must keep a golf ball stationary in an inclined position.

It consists of a rubber surface containing small alveoli. Or it is made up of a wide weft with sufficiently high and resistant fibers so that the ball does not roll
The player-wishing to train orients the carpet by tilting the cylinder (1) resting on the ground using the handles (8). From the orientation relative to the target depends the inclination of the surface (2).

 The player positions himself on the surface (2). Put his ball on the bread.

-lasson (3), then sends him with his club towards the target
By way of example, fig 1 represents a mat oriented at the target so that a right-handed player will have his ball placed on the mat higher than his feet. Conversely following a pivot of 1800 of the -tif device, Figure 2 shows a carpet oriented to the target. in such a way that a right-handed player will have his ball placed on the mat lower than his feet.

 Still by way of example, with regard to the two middle parts: In one case, the player will have to simulate the striking of a ball on a downhill court in the other case, on an uphill court.

 the carpet fig 2 with the doormat in the shape of a crown allows all the intermediate positions. In addition the cylinder (1) can only pivot mechanically.

According to particular embodiments, the height (H) simulating the slopes of a terrain can be modified and therefore adjusted
The modification of the height (H -) can title obtained by connecting the lower part of the surface (2) to the base (1) by a hinge (11)
Then the part of the surface (2) diametrically opposite to the hinge can be actuated by means of: either a hydraulic cylinder (12) or by any other mechanical system. The system can be remote controlled or not. See section fig 3
The shapes and the dimensions are given by way of example and are not limiting. In addition, the base (1) can pivot mechanically,
According to other particular embodiments, the surface (2) can have a gradual slope: see the section fig 4. Or decreasing: see the section fig 5. Which, for player1 has the effect of modifying the slope (2) when it moves on the surface of the mat. In this case the doormat covers the entire surface (2) which will be larger
According to other particular embodiments, a single mat of standard size can be moved around the periphery of the surface (2) and held in place by inks (15). As illustrated in fig 6. Here the inking of the doormat is carried out by its embedding in the surface (2) and can thus be easily moved. In the latter case the fixing of the doormat to the surface (2) is by way of example and can be obtained multiple ways
The height (R) can be modified as well as its operating mode as described: page 2 line 20
According to other particular embodiment
With reference to the section drawing fig 7 the description of the device which follows is limited to its operating principle for reasons of clarity and due to possible modifications
The device includes: - A cylindrical plate (2) in which is embedded a mat (3) - Are fixed in the center under the face of the plate (2) a gimbal (4) and an axis (5) which slides vertically in the conical base (1) - The device provided with a ring (10), an axle (6) and two wheels (7) and (7a), keeps the plate inclined relative to the base (1) - The wheels (7 and 7bis) sliding laterally on the axis (6) - using a thread or otherwise - move on the conical part (1) and thus modify the inclination of the plate (2 ) - The axis (5) slides vertically in the base (1), but is fixed by a "key-groove" system to have no rotation - on the other hand the ring (10), axis (6), wheels system (7 and 7bis) rotates around the axis (5) thus modifying the direction of the inclination of the plate (2)
This system can have functions: manual, hydraulic, electrical, mechanical, pneumatic ... Being remotely controlled or not
