Description

Equipment for a new sport related to golf.

  The subject of the present invention is equipment for a

a new sport related to golf.

  The technical field of the invention is that of the construction

truction of sports equipment.

  A sport according to the invention is akin to golf.

  only on a surface equipped with holes of diameter and

  foundry with standard golf balls and canes or "clubs" with which players must send the ball through successive holes The golf course has natural obstacles

  or artificial ones that increase the difficulty.

  The usual clubs and golf balls can send the ball up to a distance of 250 'from the starting area and the golf courses have holes that can be 500 meters apart, which leads to very extended and limit

the practice of this sport.

  It is an object of the present invention to provide novel

  new golf equipment, including new fishing rods and equipment.

  land, which makes it possible to practice a sport similar to golf, in economic conditions, particularly on land that is less extensive than traditional

  canes such as the length of the ball jets is limited.

  Another object of the present invention is to provide field equipment adapted to the conditions of this new sport, including synthetic surfaces starting the ball and arrival and easy holes to set up on land whose costs

  planning and maintenance are considerably reduced.

  The invention relates to equipment that makes it possible to practice a new sport related to golf and that requires, such as golf, holes spread over landscaped terrain, golf balls and canes to hit the balls and to send them in. the holes.

  According to one characteristic of the invention, the canes comprising

  tent a pivotally mounted head about an axis integral with the cane and this head has a prismatic shape having several faces and

  it includes means to block it in several

  each of which makes it possible to use one of the faces to strike the ball. The locking means make it possible to block the head in positions such that the balls can not be projected more than

  According to preferred embodiments, the pivoting head

  aunt has a triangular or trapezoidal cross section.

  According to another characteristic of the invention, the zones of departure and arrival of the balls are constituted by synchronous bands.

  flexible theories that are laid out on level ground and that

  have water outlets and vertical strands of such a density and rigidity that a standard golf ball rolls

  on them in a determined way.

  Advantageously, the synthetic strips used comprise perforated plastic plates provided with vertical strands.

  of the type used to constitute carpet brush.

  According to a preferred embodiment, the synonymous bands

  theories have a perforated flexible sole on which are

  fixed a central rolling band and two side braking bands.

  According to another characteristic of the invention, the holes are displaceable holes which consist of a sole and a flexible wall which has a frustoconical shape convergent upwards, the height of which is greater than the radius of a standard golf ball. and the

  sole is perforated in the part located inside the wall.

  The invention results in new equipment for practicing a golf-like sport on surface terrain

  smaller and whose development and maintenance costs are also

reduced.

  The equipment according to the invention also makes it possible to move the holes and the arrival and departure areas of the balls. They thus make it possible to modify the courses between holes and even to temporarily allocate a terrain to the practice of the new sport. equipment according to the invention make it possible to create

  seasonal sports in holiday resorts, in particular they allow

  In the summer, they are trying to create grounds to practice this new sport in winter sports resorts and to retreat the equipment.

at the end of the summer.

  All these results are achieved by using, in cooperation, new equipment that allows to practice a new sport

  which, while being a neighbor of golf, obeys different rules.

  The new rods according to the invention, with a rotating head, are designed in such a way that the orientation of the face used to hit the ball is determined so that the maximum range is limited and of the order of half of the maximum reach that can be achieved with traditional clubs which shortens the distance

  between the holes and therefore the area of the ground.

  The synthetic surfaces used to make the

  the starting and finishing areas of the ball and

  rolling faces and braking surfaces, allow to draw in the field various configurations that complicate the path

  balls to go to the holes.

  Synthetic surfaces and displaceable holes make it possible to modify courses and to create temporary playgrounds

or seasonal.

  The following description refers to the accompanying drawings which

  represent, without any limiting character, examples of

  equipment according to the invention intended for practicing a sport

related to golf.

  FIG. 1 is an exploded perspective view of the head

  pivoting of a golf rod according to the invention.

  Figure 2 is an axial section of said head.

  FIG. 3 is a cross-section along III-III of FIG.

Figure 2.

  FIG. 4 is a front view of another embodiment of

sation of a cane head.

  Figures 5 and 6 show two striking positions

of the ball.

  Figure 7 is a perspective view of a coating

of synthetic soil.

  FIG. 8 is a section of the cover according to FIG. 7.

  Figure 9 is a perspective view of a hole.

  Figure 10 is an axial vertical section of Figure 9.

  Figures I to 4 show the head of a golf club or "club" according to the invention It comprises a handle which is not shown and a head I intended to hit the balls The head I has a fixed part 2 shaped butt, which featured a

  3 axis integral with a bent sleeve 4, which is connected to the handle.

  The shaft 3 forms, with the arm of the sleeve which is fixed to the handle, an obtuse angle. The cross section of the axis 3 is smaller than the cross section of the lower end of the sleeve 4 and a spigot 5, parallel. to the axis 3, is attached to the lower end of the sleeve 4 o The head I comprises a portion 6 which serves to strike

  bullets and which is pivotally mounted on the axis 3.

  Part 6 has several faces and has the shape of a prism or a truncated pyramid. FIG. 4 is a front view of an embodiment

  of a head having a cross-section in the form of a rectangular triangle

  rule. FIG. 3 represents a cross section of another embodiment of a trapezoidal shaped head having two orthogonal faces 6a and 6b and two other faces 6c and 6d making

between them an obtuse angle.

  -The faces 6a, 6b and 6c can be used to hit the ball while normally the face 6d is a truncation intended

  to reduce the height of the head and it is not used for

  per. FIG. 3 shows that the mobile part 6 comprises, at the end situated on the side of the handle, recessed recesses 7a, 7b and 7c, in which the lug 5 is housed to block the head

  rotating in a specific angular position.

  FIG. 3 represents an example in which only the faces 6a, 6b and 6c are used and the pivoting head comprises three housings 7a, 7b, 7c corresponding to the striking positions of these

three faces.

  In the case where the face 6 d is also used, the head

  pivoting comprises a fourth recessed housing.

  The relative position of the housings 7a, 7b, 7c relative to the position of the lug 5 and the faces 6a, 6b, 6c is such that when the lug is engaged in the housing corresponding to one of the faces, this one is inclined with respect to the horizontal plane of an angle such that, when one hits the ball, this one, which leaves with, a

  velocity perpendicular to the face that hit it, follows a path

  such that the maximum distance at which a standard golf ball can be projected remains in all cases, less than 130 -35 meters, which makes it possible to bring the holes closer together and to use

less extensive terrain.

  The values of the angles are the following: the angle a between which the faces 6c and 6b are between 25 and 35 and the angle A, which is complementary thereto, therefore has a value

between 55 and 65.

  FIG. 4 represents the position of the head when the face 6c is used to strike. In this position, the face 6b forces the player to strike while holding the face 6b parallel to the ground, which precisely determines the direction initial speed

  of the ball following a curved path.

  FIGS. 5 and 6 show the two other angular positions of the movable head which make it possible to strike the ball either horizontally or with a face inclined at an angle O with respect to the ground. The angles thus defined are calculated for it is not possible to throw a standard golf ball at more than

meters.

  FIG. 2 shows that the pivoting head 6 is traversed 6 e from one end to the other by a bore 8 which is parallel to the edges of the prism and which makes it possible to engage the head 6 on the axis 3. The head 6

  has, in addition, the outer side, a counterbore 9 in the-

  which is housed a spring 10 The end of the shaft 3 has a thread 3a on which is screwed a nut 11 which engages in the counterbore 9 and which blocks the pivoting head 6 in one of the positions where the pin 5 is engaged in one of the hollow recesses 7 FIG. 1 shows the spring 10 and the nut 11 in an exploded position. A golf course has ball departure zones and arrival zones located around each hole and having an area of the order of 400 to 800 mb. On traditional courts, these departure and arrival zones. have a uniform surface on which grows turf which needs to be maintained very carefully The creation and maintenance of these areas entails high costs and, in addition, these areas can no longer

to be moved.

  Synthetic surfaces resembling an artificial turf are known which consist of relatively flexible plastic plates in which holes have been perforated whose edges are straightened to mimic grass strands. These synthetic surfaces have been used on training grounds for beginners to constitute the starting areas of the ball which are exposed to degradations daxs the case where the cane claws the turf But these synthetic turfs have tufts of strands relatively sparse and flexible, so that a golf ball that rolls on these surfaces gets into the strands and is found very quickly

  These synthetic turf can not constitute zones of ar-

  -5 riveted balls around the holes.

  Brush mats or floor mats are also known

  plastic material which are manufactured in a similar way but which

  wear denser and stiffer bristles and bullets

  golf can ride on these surfaces as on a natural grass.

  According to one characteristic of the invention,

  of the second category to constitute at least part of the starting and finishing areas of a golf course

  invention, which has the advantage of reducing the cost of pre-

  paration and maintenance and to allow to move these starting areas

  and finish to modify the courses.

  There are several types of synthetic surfaces that are used to date as a carpet brush and that can be applied

  as artificial turf for equipping a golf course.

  The characteristics of composition, height of the strands and density of these can vary in large proportions according to

  the manufacturing techniques used.

  In order to define the synthetic surfaces that can be used as artificial turf, the applicant has developed two tests which make it possible to define the synthetic surfaces capable of forming running surfaces independently of the material and the structure

who compose them.

  A first test is a restraint test A standard golf ball is placed on the synthetic surface to be tested.

  horizontal position This surface is progressively tilted

  horizontally and note the value of the angle of inclination from which the ball begins to roll If the angle of inclination is between 3 and 15, the synthetic surface is suitable as a running surface If the angle is greater than 15, the surface is braking Subject to this test, artificial turf used to date

  give an angle of friction greater than 15 will be explained below.

  how the braking surfaces are used.

  A second test is a rolling test that leads to

  select the same synthetic surfaces -The surface to be tested is

laid horizontally.

  A smooth PVC tube, 0.50 meters long and an inner diameter of 44 mm, is placed over the latter.

  inclined so that its upper end is 0.10 m above

  above the surface, the lower end of the tube touching it. A standard golf ball is rolled in the tube and is placed at the top end without a swing. If the ball runs at least 35

  cm and stops at a distance less than 70 cm, the synthetic surface

  It is suitable as a running surface.

  between 10 cm and 35 cm, the surface is a

  nante. It is specified that the synthetic plates used have perforations which are necessary for the flow of water The surfaces classified as rolling surfaces by one or the other of the two tests above, are arranged on a level ground to constitute the

  departure or arrival areas of the balls.

  Figures 7 and 8 show a new product that is manufactured and sold in the form of rolled

  spread on a flattened ground Each band has a

  12, on which are bonded for example a central strip 13 bordered on each side by two lateral strips 14a and 14b The central strip 13 is a rolling surface which has a high density of strands 15, so that a golf ball normalized 16 rolls on the hairs and penetrating only very slightly in those-cio

  The side strips 14a and 14b are braking surfaces

  The density of the tufts of strands 15 is smaller, the strands are more flexible and a golf ball 16 flattens the strands and penetrates them so that it is rapidly braked. The sole 12 and the surfaces 13,

  14a, 14b are perforated strips of natural or synthetic rubber

  tick or flexible plastic material.

  The strips according to FIGS. 7 and 8 may be laid on a level ground to form starting or arrival zones for bales, according to multiple combinations of rolling and braking surfaces, for example straight or curved juxtaposed strips or drawing any -other geometric figure in the form of checkerboard, mosaic, etc. Golf balls rolling on these surfaces, are subject to different friction forces and one of the difficulties

25419; 03

  of the new game is to avoid the braking surfaces to get into the holes The synthetic rolling surfaces fill the same

  function that well maintained natural turf, while

  braking faces fulfill the function of grassy areas of golf courses.

  Figures 9 and 10 show the holes equipping a ter-

  According to the invention, instead of being dug in the ground, these holes are placed on the artificial turf described above. Each hole has a sole 17 surmounted by a frustoconical wall 18 converging towards the top which delimits a hole. 17 is

  perforated inside the hole to allow the flow of water.

  The wall 18 has a height greater than the radius of a standard golf ball to retain it captive inside the hole It consists of an elastomer flexible enough to allow a ball to flatten it to enter the hole When placing a golf ball on the outer face of the wall 18, it must flatten completely so that its inner face comes into contact with the sole 17 Each hole has in its center a stake 19 which has a pointed end 20 which passes through the soleplate and which allows the stake to be placed in the ground and to maintain the hole in

  The post 19 allows to easily move the holes for

  difier course Each stake 19 carries a pennant 21 which

the position of the hole.

  The diameter of the holes delimited by the walls 18 are such that a standardized golf ball is housed between the stake 19 and the

wall 18.

  The equipment according to the invention makes it possible to arrange an outdoor playground at reduced costs on a ground having a

  considerably less than that of a traditional golf course.

  and to practice a new golf-like sport. They also allow for a reduced-size play area in a garden corner or indoors and, in this case, the swiveling head of the canes according to the invention is stuck in a position

  allowing only to roll the ball.
