Description
The present invention relates to a system for counting scores in ε racket sports match, such as a badminton, table tennis or tennis game, comprising at least one counting device including a transmitter, activation means and a shell in which the transmitter is accommodated, and at least one display unit including a receiver and a screen, the transmitter of the counting device being configured to transmit a signal indicating a point, following activation of the activation means, to the receiver of the display unit to display ε score based on the received signal.
In sports matches on a sub-elite level a majority of the matches are governed by the players themselves, and the players continuously need tc keep track on the score. To that end, displays are known in which numbers are flipped to indicate the score. It is, however, inconvenient to the players tc flip the numbers on a centrally positioned display at each point, and hence the score is normally committed to memory.
From badminton it is known to attach score indicators to the shaf which score indicators are scratched like a lottery ticket during the game. One disadvantage is that only the player himself or herself can see his or her owr score. Another disadvantage is that the score indicator is for single use only. DE 4006503 A1 describes an arrangement for counting and displaying the scores in a tennis match played on a court comprising two play areas separated by a net. An electronic counter and display are arranged in the fielc of vision of both players. A pulse generator placed on or in the racket of a least one player sends information on the score of each player to the countei and display via radio, ultrasound or laser. US 2007/105666 A1 describes an electronic device to be used ir rackets or paddles, comprising of an acoustic or vibration sensor, a microcontroller, a microtransmitterreceiver, a microspeaker and a display. The device is adapted to count, calculate and show in the display the game time, game speed, the score and the quantity of hits that the player gave to the ball. GB 2355203 A describes a playeroperated scorekeeping apparatus worn or carried by one player and connected by a radiocommunications lint with a remote display. For example, a wrist band supports unit provided witf pushbuttons for inputting points as they are won by either side and associatec with respective signal encoders containing stored address data for modulating the radio transmission to the display unit which incorporates data decodinc within the radio receiver to allow address storage matching before displaying the appropriate alteration to the previously displayed score. If an erroneous entry signal is received, e.g. by operating both buttons simultaneously, the display reverts to the previous score. DE 195 46 410 A1 describes a display consisting of flap or LED elements controlled by microcomputer and varying to suit the sport and othei parameters indicating the results and receiving information by radio, infrarec or ultrasonic signals. The elements are operated by transmitters clipped or the sportswear or a wrist watch of the participants. They may also operatec by a compact hand transmitter on a judge or referee outside the playing area.
With this background it is an object of the invention to provide an al ternative which is simple, practical and less costly for players to keep track or the score in a game.
This and further objects are met by a system of the kind mentioned ir the introduction which is furthermore characterized in that the shell of each a least one counting device is adapted to be releasably mounted on a racke and that a single activation means is provided.
In this manner, the counting device is easily mounted on an existing racket such that the counting device may be used and reused in games, ir which the players come with their own equipment, or borrows it. Another advantage is that such a system incorporating such a counting device is simple in its configuration and hence cost-effective to manufacture and non expensive for instance sports clubs to purchase.
In a preferred embodiment, the shell of the counting device is substantially tube-shaped and extends between a first end and a second end anc has an exterior surface and an interior surface presenting an internal diametei dimensioned to allow mounting of the counting device on a shaft of a racket The tube-shape may be formed by two or more parts which are assemblec around a shaft, or one or more parts comprising a snaplock arrangement. Ir this manner, a counting device which is simple and fast to mount or aftermount on a racket is provided, just as the balance of the racket is not affected to any noticeable extent.
In an embodiment, the shell of the counting device comprises an open section extending from the first end of the shell to the second end of the shell such that the shell may be snapped onto a shaft of a racket. This is particularly advantageous in that a particularly fast after-mounting of the counting device on a racket not provided with such device is achieved. Preferably, the distance from a first edge of the open section to a second edge of the open section is smaller than the internal diameter of the shell, which provides for a safe retention of the counting device on the racket, even under vigorous movements such as smashing with the racket. Furthermore, the flexural properties of the racket are not changed as the shell is held in a relatively loose fit on the racket.
In a preferred embodiment, the single activation means is provided in the form of a pushbutton. By pushing the pushbutton when a point is won, a signal is sent from the transmitter in the counting device to the receiver of the display unit, thereby incrementing the score. This is particularly advantageous as the counting device is fast and simple to apply as the player does not need to identify the correct activation means prior to activation. This embodiment is particularly well-suited for racket sports such as badminton, in which the score is incremental in each set, and not dependent on serving, advantages and other special rules.
In a preferred embodiment, the interior surface of the shell is substantially conical to allow mounting of the shell at the transition between a handle and a shaft of a badminton racket. The structure of a badminton racket is very well known and has dimensions, shape and weight regulated by internationally acknowledged rules. Hence, the body or frame of a badminton racket comprises a head with a stringed area, a shaft and a handle. A throat forms the transition between the head and the shaft, and at the opposite end of the shaft, another transitional area to the handle is formed. Traditionally, badminton frames have been made out of wood, but wood rackets have largely been abandoned due to the availability of lighter, more durable synthetic materials such as carbon fiber, lightweight metal alloys and ceramics. For instance, the length of the frame should be no longer than 680 millimeters or wider than 230 millimeters. The weight of a fully strung frame should be within 80 and 100 grams. Frames can come in different shapes, with larger or smaller sweet spots, and can be more or less flexible, depending on the materials used and their construction. The handle connects to the shaft and is used to hold the racket. The handle is covered with a material forming the grip. There are two types of grips: towel grips are good for absorbing moisture, but may need to be changed frequently; synthetic grips are less absorbent but more durable. Within the grip there is a core most often made of wood. One end of the handle is closed by an end cap, most often made of plastic, and at the transition to the shaft; a front cap is connected to the shaft and to the handle. The shaft is inserted into the core of the handle and fastened to the core for instance by means of a screw. The front cap also most often comprises reception means for the grip and is typically conical, but also asymmetrical and hexagonal shapes are known.
In order to enhance the retention of the counting device on the racket, the interior surface of the shell at the first end may be provided with at least one barb adapted to engage a soft material of the handle of a badminton racket, and the interior surface of the shell at the second end is preferably provided with a contact surface adapted to embrace the shaft of a badminton racket.
Particular ease of handling and operation of the system is provided in a presently preferred embodiment of the system in which the shell of the counting device comprises a space for accommodating the transmitter, a battery and further electronic equipment and delimited by a bottom facing the interior surface of the shell and an openable lid covering in a closed position the space, the lid being preferably connected to the shell by means of a first snaplock part and a second snaplock part engaging with a first abutment face and a second abutment face, respectively. Alternatively, all elements may be included in a one-piece moulded unit including the transmitter, battery and other electronic equipment. This means that the battery may not be exchanged, and is thus less preferred from an environmental point of view.
In a further development of this preferred embodiment, the space is provided in a slightly raised portion of the exterior surface of the shell, the lid being preferably flush with the exterior surface in the closed position. Thereby, optimum conditions for accommodating the transmitter, battery and other electronic equipment is achieved, without compromising the balance and comfort of the racket in use of the system.
In a further embodiment each at least one display unit comprises a first on/off button and a second reset/link button adapted to enable pairing with one of said at least one counting device.
In a yet another embodiment, said at least one display unit is mounted on a fitting adapted to be connected to a post of a net. This fitting is advantageously formed to fit standardized posts and may furthermore be shaped in a manner so that it may be adapted to various kinds of posts.
The system according to the invention may advantageously be provided as a set including two display units and two counting devices to allow each of two players to activate a respective display unit. Alternatively, three or four or more counting devices may be provided as spare counting devices.
Further embodiments and advantages are set forth in the dependent claims, and will be apparent from the accompanying description of preferred embodiments.

In a first embodiment shown in Figs 1 and 2, a counting device 1 comprising a shell 2 is shown. The shell 2 has an exterior surface 3 and an interior surface 4, of which the exterior surface 3 is mainly conical to provide an aerodynamic shape.
The counting device 1 of the embodiment shown is adapted to fit a badminton racket. Alternatively, the counting device according to the invention could be made to fit a sport equipment of a similar kind, such as a tennis racket, a squash racket or the like.
The interior surface 4 has a substantially conical shape to fit a transition from the shaft to the handle of a badminton racket, i.e. in the position in which the front cap is located. The shell 2 has a first end 5 at which a number of barbs 18 are provided. The barbs 18 may dig into a soft material and hence reduce or even eliminate the risk that the counting device 1 falls off after mounting. The shell 2 furthermore has a second end 6, at which a contact surface 19 is provided. The contact surface 19 is provided on the interior surface 4 and is adapted to embrace the shaft of a badminton racket. The contact surface 19 may furthermore comprise a ductile material such that a range of shaft diameters may be embraced. Furthermore, it is possible optionally to provide the contact surface 19 and/or other parts of the interior surface 4 of the shell 2 with a friction-increasing means, such as an adhesive, to increase the retention of the counting device 1 to a racket. In case the contact surface 19 is provided by a ductile material, this area also has a sound-dampening effect.
In the embodiment shown, the shell 2 furthermore comprises an open section 7 extending from the first end 5 to the second end 6. The open section 7 comprises a first edge 8 and a second edge 9 of the shell 2, of which the first edge 8 and the second edge 9 are located at a distance from each other that is smaller than the internal diameter of the interior surface 4 of the shell 2.
Referring to Fig. 3, the shell 2 of the counting device 1 furthermore comprises a space 10 for accommodating the transmitter, a battery and further electronic equipment. The space 10 is delimited by a bottom 12 facing the interior surface 4 of the shell 2 and an openable lid 11 covering in a closed position the space 10. The lid 11 is, in the embodiment shown, connected to the shell 2 by means of a first snaplock part 14 and a second snaplock part 15 engaging with a first abutment face 16 and a second abutment face 17, respectively. In an alternative embodiment, not shown, the lid 11 may be mounted to the shell 2 with only one snaplock part engaging an abutment face of the shell. Moreover, other ways of connecting or mounting the lid on the shell are conceivable, for instance a friction lock mechanism, a click lock mechanism or fastening means such as a screw or the like.
In the embodiment shown, the pushbutton 13 is provided on the lid 11, the pushbutton 13 acting as the activation means to activate the transmitter to transmit a signal to a receiver. The space 10 is provided in a slightly raised portion of the exterior surface 3 of the shell, the lid 11 being flush with the exterior surface 3 in the closed position. In order to provide a smooth transition between the space 10 and the first end 5, the exterior surface 3 of the shell 3 is provided with an inclined portion 20 having a steeper inclination than the remaining parts of the exterior surface 3. It is conceivable that the space is made of a more flat configuration such that the exterior surface of the shell is substantially completely conical, all parts being flush.
In the shown embodiment, the counting device 1 comprises only one activation means, viz. the pushbutton 13. In other embodiments, not shown, it is possible to provide two or more buttons to allow for more functionalities of the counting device.
In the embodiment of Fig. 4, two display units 100 are shown, mounted on a fitting 200 which in turn is mounted on the top of a post 400 holding a net 300 of a badminton court. Hereby it is possible for two players to control the two display units 100 to keep track of the scores of the respective half of the court.
The display unit 100 comprises, referring now to Fig. 5, a screen 101, a housing 102, a first on/off button 104 and a second reset/link button 103. The first on/off button 104 is used for switching the display unit on and off. The second reset/link button 103 resets the displayed score by pushing for a short time period (for instance 0.5 s), and by pushing the button 103 longer (for instance 2 s) a scan or search for a transmitter to pair with is carried out. In order to allow the pairing, the pushbutton 13 of a counting device 1 is held down, while at the same time the display unit 100 scans for a transmitter. In other embodiments, the display unit may comprise another number of buttons than two. The screen 101 is able to display numbers from 00 to 99 and the display unit 100 may be set to battery-saving or automatic switching off mode if not active for predetermined periods of time. It is conceivable to incorporate a magnet in the lower side of each display unit 100 which holds the display unit 100 in place temporarily and thus allows the display unit to be moved from one half of the court to the other when switching sides in a game.
The display unit 100 furthermore has a number of mounting elements 105 assembling the screen 101 with the housing 102. These mounting elements 105 may be in the form of screw holes and threading in which a screw is introduced or other configurations. The mounting of the display unit or units 100 is carried out substantially as described in the above. Alternatively, it is possible to mount the display unit or units with the fitting at another position in the surroundings of the court or the place where the game takes place.
Figs 7 and 9 to 13 show further design aspects of the system according to the invention.
Fig. 8a shows the parts of a badminton racket for information purposes, and Fig. 8b shows a detail of the badminton racket of Fig. 8a intended for cooperation with the counting device 1.
The dimensions and weight of the counting device are chosen to fit the requirements of being releasably mounted and retained on a racket without compromising the feel and handling of the racket. Flence, the shell 2 of the counting device 1 is for instance moulded by a lightweight durable material, such as ABS or PC. The length of the shell 2 from the first end 5 to the second end 6 lies in the range 35-70 mm, the outer diameter at the first end 5 is typically 25-35 mm and the outer diameter at the second end 6 is typically 12-20 mm. The internal diameter of the of the interior surface 4 is as mentioned dimensioned to allow mounting of the counting device 1 on a shaft on a racket and typically ranges from 10-25 mm for a badminton racket. This gives an approximate material thickness of 1-4 mm and an overall weight of the counting device 1 of approximately 4-7 g without the transmitter, battery and other electronic equipment and approximately 7-11 g including these elements. The dimensions of the open section 7 are also chosen to allow that the counting device 1 is able to be inserted over the shaft of a racket, and as mentioned the distance from the first edge 8 to the second edge 9 of the open section 7 is smaller than the internal diameter of the shell 2. For a badminton racket, this distance is approximately 8 mm thus being substantially the same as the diameter of the racket shaft. The configuration and material of the counting device are chosen such that it is possible to squeeze the shaft through the open section 7 during mounting and dismounting of the counting device without damage in order to allow for the releasable mounting provided for.
The invention should not be regarded as being limited to the embodiments shown in the drawings and described in the above. Several modifications and combinations may be carried out within the scope of the appended claims.
The different features of the embodiments may be combined.
