Description

-1- 2392246
Device for measuring the speed of an object The present invention relates to a device for measuring the speed of an object, for use particularly, but not exclusively, for measuring the speed of an object used in a sports game.
Many sports are based on the movement of an object, most commonly a ball. Recent technology has allowed the speed at which these balls travel to be known. This provides an added interest for both the players and the viewers, for example, the fastest serve in Tennis, or the fastest pitch in Baseball.
The technology used to record the speed of a ball is based on measurements taken as the ball passes through space, for example with a known type of infrared or laser "speed gun". This kind of technology is sophisticated and expensive, and is therefore not available to the amateur enthusiast. Further, this equipment may require a user who is not participating in the game who can aim the device at the moving ball.
The present invention is intended to provide an alternative approach.
According to the present invention a measuring device comprises pressure measuring means adapted to be fitted to a first sports implement and further adapted to record the contact pressure between the first sporting implement and a second sports implement, processing means to calculate from the pressure recorded, the speed at which the second sports implement was travelling before and/or
-2 after it impacted the pressure measuring means, and means to communicate the speed calculated.
In a first construction the first sports implement can be a striking object, for example a football boot, and I the second sports implement can be an object which is struck, for example a football ball. It will be appreciated that with this arrangement it is the speed of the ball after it was struck by the boot which is displayed.! In an alternative construction the first sports implement can be an object which is struck, for example a baseball glove, and the second sports implement can be a striking object, for example a baseball ball. It will be appreciated that with this arrangement it is the speed of the ball before is was caught by the glove which is displayed. The pressure measuring means can be a transducer sensor of a known type, which is adapted to provide an electrical signal to the processing means which corresponds to the pressure recorded when the two sports implements collide. The processing means can be an electronic circuit constructed from known materials and to a known formula.
The circuit can be progra Dable, so it can be provided with information about the physical properties of the first and/or the second sports implement in order to accurately calculate a speed from the impact pressure recorded.
The communication means can be a visual display, which is provided on the measuring device. The visual I display can be a liquid crystal display. In an alternative construction the communication means can be an audio
-3- signal, for example a recording of a voice speaking the speed recorded.
The communication means can also be provided on a second base, connected to the processing means by a remote signal. In one construction the communications means can be provided on a watch, which can either display, or audibly communicate the speed calculated once the remote signal is sent to it.
The processing means and/or the LCD can be provided on the opposite side of the device to the transducer, and therefore the opposite side of the sports implement to the side of impact.
The invention can be performed in various ways but two examples will now be described by way of example and with reference to the accompanying drawings in which: Figure 1 is a perspective view of the component parts of a measuring device according to the present invention; Figure 2 is a perspective view of the device shown in Figure 1; Figure 3 is a perspective view of the device shown in Figure 2 fitted to a football boot,; Figure 4 is a perspective view of a second measuring device according to the present invention; Figure 5 is a perspective view of the device shown in Figure 4 fitted to a baseball glove; and,
-4 Figure 6 is a further perspective view of the device shown in Figure 4 fitted to a baseball glove. In Figures 1, 2, and 3 a measuring device 1 is adapted to be fitted to a football boot 2. The device 1 comprises a transducer sensor 3 which is adapted to record the contact pressure between the football boot 2 and a football (not shown), an electronic circuit board 4 adapted to calculate from the pressure recorded by the transducer 3 the speed at which a football was travelling after it was struck by the boot 2, and an LCD display 5 to display the speed calculated.
The device 1 further comprises a base 6, a foot strap 7, a heel strap 8, a housing 9 and a resilient outer cover 10. The transducer 3 is secured to the base 6, and is provided with a cover 11. The outer cover 10 is secured on the base on top of the transducer 6. The housing 9 comprises a base 12 and an outer cover 13. The circuit board 4, the LCD display 5 and a battery 14 are contained within the housing g. The base 12 is provided with an opening 15 and a removable cover 16, though which the battery 14 can be removed and/or replaced. The housing 9 is secured to the heel strap 8, and the heel strap 8 and the foot strap 7 are secured to the base 6 by means of pivot joints 17 and 18.
The transducer 6 is disposed in an off-set position on the base 6, which corresponds to the spot where a football is traditionally struck by a football boot.
As shown in Figure 3 the device 1 is fitted to a football boot 2 by placing the base 6 on the upper 19 of the boot 2, and placing the foot strap 7 around the body 20 1 of the boot 2, and the heel strap 8 around the heel 21 of
-5 the boot 2. The device 1 can be provided with an operating switch (not shown) to turn it on.
In use the operator fits the device 1 to their football boot, and switches it on. They then strike a football in the traditional manner. As a result the transducer 3 is placed under a contact pressure and a measurement is taken. This measurement is sent to the electronic circuit board 4 via insulated wire 22 (as shown in Figure 1). The circuit board is programmed to translate the pressure recorded into a speed according to a programmed formula, and the result is then displayed on the LCD display 5. It will be appreciated that the speed recorded will only be accurate if the resilience of the ball corresponds to the information about the ball which has been programmed into the circuit 4. It will be further appreciated that the device 1 will only provide an accurate reading if the ball is struck by the portion of the boot 2 adjacent to the transducer 3.
To assist in the accurate use of the device 1 a pattern 23 is displayed on the outer cover 10 which shows where a ball should be struck by the foot.
As shown in Figure 3 the housing g is on the opposite side of the boot to the striking area 24. With this arrangement the housing 9 will not be damaged when the boot comes into contact with the ball.
It will be appreciated that the above described device 1 can be adapted to be used with any sporting implement which is used to strike another sporting implement, without departing from the invention.
-6- In Figures 4, 5 and 6 a measuring device 25 is adapted to be fitted to a baseball glove 26. The device 25 comprises a transducer sensor (not visible) which is adapted to record the contact pressure between the glove 26 and a baseball ball (not shown), an electronic circuit board (not visible) adapted to calculate from the pressure recorded by the transducer the speed at which a ball was travailing before it was caught by the glove 26, and an LCD display 27 to display the speed calculated.
The device 25 operates in substantially the same way as device 1 shown in Figures 1, 2 and 3. The device 25 comprises a base 28, upon which the transducer is mounted, and covered by an outer cover 29. A housing 30 is provided which contains the circuit board, battery and LCD display 27 required to operate the invention.
In use the device 25 is fitted to a glove 26 by means of straps 31. The housing 30 is secured to the rear of the wrist portion 32 of the straps 31. The user activates the device 25 by means of switch 33, then catches a flying ball. The contact pressure recorded by the transducer is then sent to the circuit, and a speed is calculated and displayed on the LDC display.
As shown in Figure 6 the housing 30 is on the opposite side of the glove to the ball catching area, so it will not be damaged in use.
It will be appreciated that the above described device 25 can be adapted to be used with any sporting implement which is used to stop or catch another sporting implement, without departing from the invention.
-7 Thus a device is provided which is cheap to manufacture and to purchase, and which can be used to calculate the speed of sporting implements without the need for a third party using a separate measuring device.
