Abstract

The support described comprises at least one horizontal plate (5) on which is depicted in miniature a traditional rectangular sports field (50) divided into several fixed main zones (51, 57) by lines (53, 54, 61) parallel to the shorter sides of the rectangle (50). A set of additional lines (58, 59) parallel to the shorter sides of the rectangular field (50) constitutes sampling means for determining the incremental displacements of markers representing a ball (62) or players (63, 64) on the plate (5) in the secondary zones. The position of said sampling means (58, 59) can be adjusted in order to change the arrangement of the lines which divide the main zones (51, 52) into secondary zones so as to vary the number of secondary zones in each principal zone (51, 52) while maintaining the total number of secondary zones constant. This makes it possible to simulate the actual movements of a ball and players corresponding to a given type of field, in respect of the damping parameters of the bouncing of a ball and speed of play.

Description

Board game support played with dice, for simulating a ball game, such as a tennis game.

 The present invention relates to a board game support played with dice, for the simulation of a ball game, such as a tennis game, in which a ball must progress by successive rebounds on both sides. other of a median line of a conventional rectangular terrain divided by lines parallel to the short sides of the rectangle into several immutable main zones for the practice of said ball game comprising at least one horizontal plate on which is represented on a reduced scale the representation of said conventional rectangular playing field, pawns representing players, a ball or accessories intended to be placed on said horizontal plate and one or more dice to be played, the horizontal plate on which the representation of the conventional rectangular playing field is materialized sampling means making it possible to define incremental displacements of the pawns representing the ball or the players on the plate horizontal; and said sampling means comprising a set of traces parallel to the short sides of the conventional rectangular terrain to divide each of the main immutable zones such as defense and volley zones, into at least two secondary zones, each half of the rectangular terrain being subdivided in a predetermined number of secondary zones of between 6 and 8, and preferably equal to 7.

We already know, for example, by the patent document
FR-A-922 097, a board game support of this type, in which a game board reproduces a tennis court and also shows divisions of the court in equal squares in the manner of a checkerboard. Each main area of the tennis court is thus immutably divided both in the width direction and in the length direction in a predetermined number of boxes each corresponding to the advancement of the pawns by an amount corresponding to a no dice.

 With such a type of support comprising the representation of a playing field subdivided into a regular course in two directions perpendicular to each other, it is not possible to produce a game which can simulate in a sufficiently realistic manner a real part of a playing game. tennis with a given nature of the field, or to perform a game in which the strategy chosen by the players is of decisive importance, despite the use of elements of determination by chance, such as dice.

 The present invention aims to remedy the aforementioned drawbacks and to provide a game support making it possible both to authorize a significant initiative on the part of the players and to simulate realistically a game corresponding to particular predetermined playing conditions.

 These goals are achieved by means of a game support of the type defined at the head of the description, characterized in that the position of said sampling means is adjustable to modify the distribution of the tracks dividing the main zones into secondary zones so as to change, with the same total number of secondary zones, the number of secondary zones of each of the main zones in order to allow the simulation of real movements of a ball and of players corresponding to a given type of terrain as regards the parameters for damping rebounds d 'a ball and speed of play.

 Preferably, the game support comprises a base plate secured to a rectangular frame with a triangular section having four external vertical faces and four internal faces attached to the external vertical faces and inclined downwards towards the central part of the plate. based.

 According to a first possible embodiment, the base plate and the rectangular frame define a housing for receiving a removable horizontal plate on which is represented on a reduced scale the representation of said rectangular terrain, and in that a set of several plates is provided removable provided with representations of said rectangular terrain on which the distributions of traces dividing the main areas into secondary areas are different.

 The inclined upper faces of the triangular section frame bear, near their end facing the center of the base plate, a strip of low height forming a stop for dice and which can also serve as an information medium.

 Advantageously, the base plate and the rectangular frame are divided in their median part parallel to the short sides or to the long sides of the conventional rectangular terrain, and are provided with elements forming ~ hinge to constitute a folding game support when the removable plates are removed from their housing defined by the base plate and the frame.

 According to a second embodiment, the game support comprises a rigid fixed transparent horizontal plate, at least one strip of flexible material disposed in a housing under the fixed rigid transparent horizontal plate and comprising several representations of said rectangular terrain on which the distributions of the traces dividing the main zones into secondary zones are different, and adjustment means for superimposing one of the representations of said rectangular terrain with the fixed transparent horizontal plate.

 In this case, the strip of flexible material may consist of a continuous strip cooperating with return wheels actuated by at least one control button.

 According to yet another embodiment, the game support comprises a fixed rigid transparent horizontal plate, a set of rods arranged in a housing under the fixed transparent horizontal plate to materialize lines of subdivision of the main zones into secondary zones, said rods being movable in the lengthwise direction of the rectangular terrain.

 In the various possible embodiments, preferably the immutable main zones of the conventional rectangular terrain are subdivided into secondary zones exclusively by lines parallel to the short sides of the rectangular terrain.

Other characteristics and advantages of the invention will emerge from the following description of particular embodiments, given by way of examples, with reference to the appended drawings, in which

FIG. 10 is a view in longitudinal section along line XX of FIG. 9, and
- Figure 11 is an elevational view of the game support according to Figure 9 showing a longitudinal face of the support frame provided with means for adjusting the subdivisions of the main areas of the tennis court into secondary areas.

 Figures 1 to 3 show a first example of board game equipment played with dice and allowing the simulation of a ball game which, in the example considered, is a tennis game.

 The playing equipment comprises a base plate 1 secured to a rectangular frame 2 with a triangular section having four external vertical faces 22 and four internal faces 21 attached to the external vertical faces and inclined downwards towards the central part of the plate. basic 1.

 The base plate 1 and the rectangular frame 2 define a housing for receiving a removable horizontal plate 5 on which is shown on a reduced scale the representation of a conventional rectangular court 50, which in this case is a tennis court.

 The inclined upper faces 21 of the frame 2 of triangular section carry, near their end facing the center of the base plate 1, a strip 3 of low height which forms a stop for the dice and. can also serve as an information medium.

 An element 61 representing a miniature net can come to rest or snap onto the plate 5 at the median separation of the representation 50 of the tennis court.

 The base plate 1 and the rectangular frame 2 are divided in their middle part parallel to the short side 53 of the conventional rectangular terrain 50 and are attached by a strip of fabric 4 forming a hinge. When the plate 5 is removed from its housing defined by the base plate 1 and the frame 2, the game support can be folded up at the hinge 4.

 The game equipment includes, for example, two classic dice 65, 66 with six faces, a die 67 which can have 12 faces, one or more pairs of pawns 63, 64 constituted by figurines representing the players, and a pawn 62 representing a ball.

 In the storage position, when the play equipment is not used, the support comprising the base plate 1 and the rectangular frame 2 is folded at the hinge 4 and, as shown in dotted lines in FIG. 3, all of the two halves of game support can be integrated in a housing 7. The various game accessories such as the net 61, the pawns 62, 63, 64, the dice 65, 66 and the 12-sided die 67 can be placed, as well as additional elements such as a marking table, in a box 6 whose dimensions correspond to half of the housing receiving the plates 5. The removable plates 5 preferably have dimensions less than or equal to half of the rectangular support constituted by the base plate 1 and the rectangular frame 2, so that they can be incorporated in a box 7 corresponding to the dimensions of the support 1, 2 in the folded position at the hinge 4. The whole set can thus be relatively compact. and in the storage position, while in the playing position when the base plate 1 and the frame 2 are unfolded, the playing surface for moving the pawns on the representation 50 of the tennis court, and the space for throwing the from 65, 66, 67 can be relatively large. In the playing position, as shown in solid lines in FIGS. 1 to 3, a removable plate 5 placed in the housing defined by the base plate 1 and the frame 2 contributes to prevent the support defined by this base plate 1 and the frame 2 from being folded involuntarily by one of the players.

 The support frame 2 which in particular makes it possible to reserve an additional space for throwing the dice can symbolize a rectangular stadium in relief, each side of the stadium consists of an inclined plane 21 representing the stands on which the public stands. The raised strip 3 situated at the bottom of the inclined planes symbolizing the steps constitutes a slightly raised part which can receive, for example, advertising but can also serve as a stop strip for the dice thrown possibly at the level of the frame 2.

 The presence of a removable plate 5 on which is represented the drawing of a tennis court is important, because it is thus possible to choose a representation of tennis court corresponding to a specific type of surface conferring a particular playing atmosphere, without that the rules of the game are themselves changed.

 By way of example, the play equipment may comprise a set of three removable plates 5 each comprising the representation of a tennis court 50 but each provided with a set of specific subdivisions 58, 59 which allow the tennis court 50 to simulate a particular surface of ground such as for example, clay, turf, or cement (nature of ground qualified as "quick").

 The playing equipment can thus include a set of three surfaces constituted by the most representative surfaces of the international tennis circuit, namely the surface of the internationals of France at Roland Garros, the surface of the internationals of Great Britain at Wimbledon and the surface internationals from the United States at Flushing Meadows.

 Each representation 50 of a tennis court on a removable plate 5 comprises subdivisions into fourteen boxes numbered from 1 to 7 in each half of the field, the boxes being delimited by lines 58, 59 parallel to the short side 53 of the field.

As can be seen by considering Figures 4 to 6, the division of each field 50 located on a removable plate 5 is specific to this field and gives it a playing atmosphere similar to that found on a surface d '' a given type in tennis and different from each of the other two surfaces
As can be seen in FIGS. 4 to 6, the representation 50 of a tennis court appearing on a removable plate 5 comprises the traditional lines of a classic tennis court, namely bottom lines 53, lines of side 57 for the game of doubles, side lines for singles 56, a center line 55 and service lines 54. it is thus defined classic main areas inside the tennis court, namely defense areas 51 located between the baseline 53 and the service lines 54, and volley zones 52 located near the net 61. The main zones 51, 52 are immutable, whatever the type of terrain chosen. On the other hand, lines 58, 59 whose location depends on the type of terrain chosen, constitute sampling means making it possible to define incremental displacements of the pawn 62 representing the ball or pawns 63, 64 representing the players on the plate horizontal removable 5. The lines 58 are parallel to the short side 53 of the tennis court 50 and are located in the defense zones 51 while the lines 59, which are also parallel to the short side 53 of the tennis court 50 are located in the flight zones 52. Each of the immutable main zones 51, 52 is thus divided into at least two secondary zones.

 The use of removable plates 5 having different distributions of the lines 58, 59 constituting the sampling means making it possible to define displacements by increments for the pins 62, 63, 64, makes it possible to carry out a game which, with the same rule The game simulates the actual movements of a ball and of players corresponding to a given type of terrain in terms of the parameters for damping the rebounds of a ball and the speed of play.

 This is made possible by the fact that the distribution of the tracks dividing the main zones into secondary zones is modified according to the plate 5 chosen, that is to say according to the type of terrain 50, so as to adapt the number of secondary zones of each of the main zones to a given terrain, while retaining an identical total number of secondary zones defined by traces 58, 59.

 By way of example, we see in FIG. 4 a representation of terrain 50 which aims to symbolize a clay court and includes, for each half of the court, a defense zone divided into four secondary zones by three lines 58 and a zone of flight 52 divided into three secondary zones by two lines 59.

With this distribution of lines 58, 59 constituting the means of sampling the terrain, the game will tend to develop in the defense zones, as in a real competition on clay.

 FIG. 5 represents a tennis court 50 intended to simulate a cemented surface, such as the surface called "quick".

In this case, the defense zones 51 are subdivided into three secondary zones by two lines 58 while the volley zones 52 are subdivided into four secondary zones by lines 59.

With this type of distribution of the secondary zones, the game will take place in a balanced way throughout the field.

 The tennis court 50 shown in FIG. 6 aims to allow the simulation of a game on a grassy surface and has defense zones 51 which are only divided into two secondary zones by a line 58 while the volley zones 52 are themselves subdivided into five secondary zones by four lines 59. Such a distribution of lines 58 and 59 leads to a concentration of play near the net 61, as is the case in reality on turf surfaces for which the bounces of the ball are more damped than on other types of surfaces.

 It is important to note that whatever the type of representation of the nature of the terrain chosen, the rules of the game remain identical, but the player must adapt his strategy according to the surface determined taking into account a different evolution of the game imposed by the specific distribution of subdivisions within the traditional areas of the tennis court.

 We will briefly indicate how the board game equipment according to the invention can be used according to a particular game rule.

 The object of the game is to earn maximum points, games and.

sets by following the rules of tennis and by combining chance and strategy. It is a matter of advancing the ball on the court 50 on either side of the net 61 with the help of dice 65, 66, 67. The game can be done by hitting all the existing tennis strokes (service, volley, passing, amortized, lob, smash ...). The players can follow the tactics of the game of tennis as well in the relaunch of the ball as in their placement on the ground, and the strategy, which is fundamental differs according to the surface on which the game is supposed to perform, thanks to the specific cutting of the different game surfaces.

 The way of counting points is identical to that of tennis and the game can be played in three or five sets at the whim of the players who decide before starting, in singles or doubles.

During the game, each player moves the pawn 62 representing the ball and a pawn 63 or 64 representing the player of his side.

 The service is played with the special 12-sided service die 67 which has various indications on its faces, namely numbers such as 1, 2, 3, 4, letters, such as a, 1, f respectively symbolizing as, let, fault. Thus, if the service die indicates a, the server immediately scores the point without the opponent throwing the dice. If the service die 67 indicates 1, the server raises the service die for a new attempt, if the service die indicates f, the server raises the service die for its second attempt and if it again makes a fault, i.e. if the dice again indicates f, there is a double fault and the point goes directly to the opponent. If the service die indicates one of the digits 1, 2, 3 or 4 for example , the server places the ball on the other side of the net on the box which bears the number indicated by the service die, the various boxes being numbered on the tennis court 50 in an ascending direction from the net 61.

 After serving, the server places his pawn representing the player he is handling on the square of his choice, or leaves him at the back of the court, to have the best possible placement before receiving the return from the opponent. Throughout the exchange, it is the position of the pawn representing a player on the court which will determine his strategy. Indeed, the position on the court gives certain forces but also certain handicaps which can be defined in advance in the rules of the game.

 Exchanges are made using one or two exchange dice 65, 66 at the player's choice. After the service, it is up to the opponent to roll the exchange dice 65, 66 to return the balla. Each player is free to throw one or both exchange dice depending on whether he wants to return the ball more or less far, depending on the position taken by the opponent. After having thrown the 65 or 66, the player advances the ball towards the opponent as many spaces as the number indicated by the dice. If this number is insufficient, the ball goes into the net. If this number is too large the ball comes out. In both cases, the point goes to the opponent.

 After placing the ball, the player on turn chooses to place the pawn representing his tennis player on one of the seven squares on his side, or chooses to leave it at the bottom of the court.

This position determines his tactics during the exchange. In the single game, the player occupies the division over the entire width of the field, but it is different in the double games.

Then, the opponent throws the dice (s) in his turn to return the ball and choose the placement of the pawn representing his tennis player on the court. The exchange continues thus, each player throwing the dice in turn.

 Any ball that falls exactly on the square where the opposing tennis player is located gives the point directly to the latter.

 A pawn 63, 64 representing a tennis player in the stolen position marks the point if the ball 62 is returned to the square it occupies, but also if it is returned to the square immediately in front of him.

 If the ball is returned to the box immediately behind the opposing tennis player, it gives the latter the opportunity to smash. In this case, it must say smash. The other player must place his tennis player in the baseline position. To smash, the player must roll the two exchange dice and force his opponent to stay in the baseline position and play the next stroke with only one die. In this case, if the ball falls on square 1, it is not a cushioning and the game continues.

 In all other cases, any ball that falls immediately behind the net in box 1 is said to be amortized. It scores the point if the opponent is in defense or baseline.

 If the ball is returned two spaces behind the position occupied by the opposing tennis player, there is passing and the latter loses the point if he was in the volley position. If he was in the defense position, he must retreat to the baseline position before playing the next stroke and stay there.

 If the ball is returned three or more hexes behind the opponent's position, there is a lob and the latter loses the point.

 The game can in the same way be played in double with four pawns representing two pairs of players 63, 64. For double games, the basic rules are the same as those of single games, but some particularities must be planned at the level of the rules of the game. These particulars will not be explained in more detail in the context of the present description which essentially concerns the game support which is not itself modified according to whether the game is played in single or double with one or two pairs of pawns 63, 64.

 FIGS. 7 and 8 illustrate another embodiment of the game support according to the invention, making it possible to adjust the position of the lines 58, 59 so as to be able to modify the distribution of the traces dividing the main zones 51, 52 into secondary zones. The accessories such as dice, pawns or miniature net are identical in the case of the embodiment of Figures 1 to 3 and in that of Figures 7 and 8 and will therefore not be described again. The actual game support can itself be presented in a manner similar to that of FIGS. 1 to 3, by comprising a base plate 101 secured to a rectangular frame 102 of triangular section having four vertical exterior faces 122 and four inclined upper faces 121 attached to the external vertical faces 122. A strip 103 of low height forming a stop and if necessary an information carrier can also be superimposed on the upper inclined face 121 of each part of the frame 102, in a similar manner to strip 3 of Figures 1 to 3.

 The game support of FIGS. 7 and 8 is not foldable and does not include a housing for removable plates 5. On the other hand, a transparent rigid plate 105 is placed horizontally at a fixed post inside the frame 102 parallel to the bottom plate 101 at a location which corresponds to the housing of the support in FIGS. 1 to 3 intended to receive a plate 5. A flexible strip 108 is placed in a housing under the rigid transparent horizontal plate 105 and comprises a succession of several representations of the tennis court 50, on which the distributions of the traces 58, 59 dividing the main zones 51, 52 into secondary zones are different. Thus, the strip 108 can for example successively comprise three configurations of tennis court 50 corresponding to the configurations of FIGS. 4, 5 and 6 respectively. The flexible strip 108 can consist of a continuous strip provided with perforations 189 which cooperate with pins 186 , 187 of return wheels 181, 182 rotating around axes 183, 184 respectively.

A roller 188 can be provided to keep the flexible strip 108 under tension. One or two control buttons 185 allow one of the idler wheels 181 to rotate to adjust the position of the strip under the transparent plate 105. At the start of each part, it is thus possible to choose the type of terrain 50 having a predetermined division by lines 58, 59, which we want to appear under the plate 105. As in the case of the embodiment of Figures 1 to 3 , it is thus possible to choose a site 50 whose specific subdivisions into secondary zones correspond to a particular type of soil. The flexible strip 108 may be provided with perforations 189 cooperating with the pins 186, 187 of the idler wheels 181, 182, but other types of drive, for example of the friction type, are possible.

 We have considered the case where the rigid transparent plate 105 has no inscription, while the representation of a tennis court 50 provided with its traditional lines 53 to 57 as well as the sampling means constituted by the additional lines 58, 59 appear on the flexible strip 108. It would however be possible to show on the transparent plate 105 the various immutable lines 53 to 57 which define a classic tennis court 50 and which are not modified according to the nature of the ground, while the various additional lines 58, 59 with variable spacing intended to divide in a specific manner the main zones 51, 52 of the playing field 50 into secondary zones, as well as the identification numbers 150 of these secondary zones would only be carried on the flexible strip 108 to be superimposed on the design of the traditional tennis court 50 represented on the fixed plate 105.

 FIGS. 9 to 11 represent yet another embodiment of the invention and relate to a game support in which the elements 201, 202, 203 and 205 correspond respectively to the elements 101, 102, 103 and 105 of the embodiment of the figures 7 and 8. However, in the case of the embodiment of FIGS. 9 to 11, no flexible strip is used which can be slid under the fixed transparent plate 205. In the case of the embodiment of FIGS. 9 to 11, the representation 50 of the traditional tennis court, with its lines 53 to 57 is carried out on the fixed transparent plate 205, while a set of sliding rods 281 is disposed in a housing defined by the plate 205 and a plate 284 parallel to the plate 205, to materialize the lines 58, 59 dividing the volley 52 and defense 51 zones of the tennis court 50 into secondary zones.

 The rods 281 forming cursors can be extended by extensions 283 under the frame 202 to emerge at least on a vertical face 222 of the frame 202 in order to allow manipulation of the latter by the players. For this, each rod 281 extended by an extension 283 advantageously ends in a swollen or enlarged part in the form of a control button 285. Each rod 281 carries a small label 282 on which. there is a number 150 for identifying a secondary zone defined by the line 58 materialized by the rod 281 concerned.

 By adjusting the position of the different rods 281, it is possible to reconstitute for example the three terrain configurations subdivided into secondary zones shown in FIGS. 4, 5 and 6. The vertical face 222 of the frame 202 on which the control buttons 285 emerge sliding rods 281 can bear locating indications 290 making it possible to locate the position of rods 281 for various terrain configurations corresponding to particular types of soil. Thus, for example, in FIG. 11, the triangular marks correspond to the configuration of the terrain represented in FIG. 5, the square marks correspond to the configuration of the terrain represented in FIG. 6 and the marks in the form of circles correspond to the configuration of the terrain represented in FIG. 4, the rods 281 being themselves arranged to match the configuration in Figure 5.

 The rods 281 have been shown as moving in translation in the longitudinal direction of the terrain 50, in the free space forming a slide delimited by the plates 205 and 284. Guiding the rods 281 may naturally be possible, for example by means of small toothed wheels integral with the rods 281 and meshing in a rack disposed parallel to the long sides 57 of the ground 50, the labels 282 then being themselves mounted so that the rods 281 are free to rotate relative to the latter.

 As in the case of the embodiment of Figures 1 to 3, the game support of Figures 7 and 8 with its frame 102 can be incorporated in a housing 107, while the accessories will be arranged in a housing 106 placed inside of the housing 107, and the frame 202 of the embodiment of the figures 9 to 11, can be placed in a housing 2Q7 while the accessories are arranged in a housing 206 itself integrated inside the housing 207 in the storage position .

 The pins 62, 63, 64 representing the ball and the players can be temporarily fixed on the upper surface of the horizontal plate 5, 105 or 205. The means for temporarily fixing the pins can be in particular of the mechanical type, for example by snap-fastening , magnetic or adhesive and can be formed according to the embodiments on the basis of the pins and / or on the horizontal plate 5, 105, 205.

 Of course, various modifications and additions can be made to the embodiments which have just been described. Thus, in the case of the embodiment of FIGS. 9 to 11 for example, the extensions 283 of the rods 281 can be curved and emerge vertically so that the control buttons 285 are located on the upper faces 221 of the frame 202 and not on the vertical faces 222.

 Furthermore, the subdivisions formed by lines 58, 59 may be different from those indicated in Figures 4 to 6, to simulate for example another type of land such as wood or chipboard.
