Sport counting and timing device

Abstract: An athletic performance measuring device is provided which can be conveniently worn on the user's finger is disclosed. The device can provide a variety of functions such as lap counting and timing. An actuator is provided in the form of a thumb switch, to allow the counter/timer to be held and operated by one hand, without disrupting the athlete's performance.

Description: The invention relates to a device for measuring athletic performance with the features of the pre-characterizing part of claim 1. Timing devices are well known for use by athletes or observers of athletes, for measuring athletic performance in various sports, including running, skiing, bicycling and swimming. Often the timing device is in the form of a stopwatch which is started concurrently with the starting of an event or practice, and which is stopped upon completion of the event, such that the total elapsed time is measured. Conventional stopwatch devices are often hand held and bulky, making it cumbersome for an athlete to carry the device during an event or training. In addition, hand held stopwatches may be dropped as the athlete is performing or training resulting in damage or loss of the timing device. DE - A - 30 36 056 as the starting point of the present invention discloses a sport timing device which includes a timer being fixed to a paddle which preferably may be used by a swimmer. For measuring the elapsed time the swimming needs for a certain distance the swimmer is able to press the actuator to start and stop the timer. The paddle of rectangular shape is disclosed to be of elastic material and two elastic rings of different size are connected to the paddle on both sides of the timer. The swimmer is able to wear this timing device in a way that the larger ring is positioned around the wrist and the smaller ring around one finger of the same hand. Thus the timer is lying against the flat of the hand and the swimmer is able to start and stop the counter with his thumb. The sport timing device from this prior art has the main disadvantage that the user, i.e., if he is wearing this timing device, the swimmer is hindered very much, because he cannot move his hand freely. Moreover, the area of the hand is enlarged, so that the swimmer is able to swim more effective with this hand and thus becomes faster than he would be in a real competition. US - A - 4,117,662 further discloses a ring mounted watch having a display face and an actuation mechanism to illuminate the display face. This actuation mechanism comprises at least one knob on the side of the watch case of the ring whereby it can be actuated by an adjacent finger. By actuation of one of the knobs not only the illumination of the display face can be actuated but also a change between displaying the time in hours and minutes and the actual date alternatively. Additionally it is disclosed that by actuating this knob the time can be displayed also in seconds. Thus, there is a need for a counting and/or timing device which can be comfortably worn by the athlete or an observer, and which can perform a variety of functions desired to measure athletic performance in a wide variety of sporting events and can be operated by only slight movement by the user. Thus it is the primary object of the present invention to provide a device for measuring athletic performance which can be conveniently and comfortably worn by a participant or observer of various sporting activities. The aforementioned object is achieved according to the present invention by a device for measuring athletic performance with the features of the characterizing part of claim 1. The major advantage of the present invention over the prior art is that the athlete wearing such a device for measuring athletic performance is not disturbed or hindered by this device due to the smallness of the overall shape of this device. Due to the fact that it can be worn on even one finger of the right or left hand by an athlete the hand and even all fingers can be moved freely without being hindered in any movement. Additionally the device shows only a small and thus neglectable drag which especially is necessary for a swimmer who wants to measure the elapsed time he needs to swim a certain distance under conditions of a real competition. But the use of the device according to the present invention is not limited to swimming, it also may be used by a participant in measuring his own performance without substantial hindering the performance in activities such as running and cycling, too. It is another advantage of the invention that the counting and timing functions are actuated by a single switch or actuator, a variety of information is requested and the user is provided with various indicia of athletic performance. A further advantage of the invention is that the user is provided with a distance indication in the form of a counter for counting known distance increments (for example, laps of a track or a swimming pool) and with an indication of time in the form of total elapsed time and/or elapsed time for each lap or distance increment. Other characteristics and advantages of the present invention will become apparent from the following detailed description, when read in conjunction with the drawings. Fig. 1(a) is a perspective view of the counting/timing device of the present invention mounted on the index finger of a user's hand. Fig. 1(b) shows an enlarged perspective view of the counting/timing device of Fig. 1(a). Fig. 1(c) shows a top plan view of a counting/timing device of the present invention. Fig. 1(d) is a side view of the counter/timer of the counter/timer of Fig. 1(b). Fig. 2(a)-(c) show block schematics of various circuits which may be utilized in accordance with the present invention. As shown in Figure 1(a), the present invention relates to a counter/timer 10 which may be mounted upon one or more of the user's fingers, and preferably upon the user's index finger, between the first and second joints. As shown in Figures 1(a) and 1(b), the device 10 includes a ring-like structure 12 for mounting upon a finger. The mounting portion 12 can include two arcuate members 12a, 12b separated at a slit 12c, with the arcuate members 12a, 12b resilient such that they may be mounted upon fingers of various sizes. Due to the resiliency of the plastic or other material utilized in forming the arcuate members, they will be biased toward one another to hold the counter/timer about a finger, but will yield sufficiently to allow mounting upon a finger. It is to be understood that a number of other mounting means may be utilized. For example, a neoprene or other elastic band may be utilized to firmly hold the counter/timer about the finger. The above split-ring and elastic band are advantageous in that they can easily accommodate a large range of finger sizes, and thus individual sizing is not necessary. A band which is adjustably attached about the finger, for example, by VELCRO (registered trademark), may also be utilized. It is also to be understood that, while mounting upon a single finger is illustrated, the timer/counter of the present invention may also be mounted about two or more fingers if desired. A resilient rubber-like member 14 is also preferably provided at the top of the mounting device 12, to further ensure a snug fit upon the user's finger. The member 14 may include, for example, a neoprene pad which is resilient to allow mounting and removal of the timing/counting device, while ensuring a snug fit of the counter/timer during use. This is particularly important in sporting activities such as swimming in which a large force may be imparted to the device as it is moved through the water during a swimming stroke. The top portion 19 of the device can include a two piece housing in the form of a top housing portion 20 and a bottom housing portion 22. The top and bottom housing portions are removably attached, for example by screws, such that the top portion may be removed to allow for recharging or replacing of batteries. If desired however, particularly in inexpensive versions, the housing can be substantially one piece, with the counter/timer discarded after the batteries expire. Alternatively, connectors for a charging unit may also be provided, such that batteries may be recharged without opening the housing. The housing should be formed of a water impervious, shock-resistant material, for example injection molded plastic. The top portion of the housing includes a display 24 which can display counting and/or timing information. The display is preferably in the form of an LCD, however other known display means may be utilized. Since the display is mounted on the finger, it is easily read while an athlete is training, as the athletes need only rotate their hand slightly to view the display. In contrast, in prior art devices such as wrist or glove mounted timers, movement of the user's arm was necessary to view the display. An actuator, or switch 28 is provided such that the counting and timing functions may easily be actuated by the user's thumb by either rotating the thumb toward the index finger, or by rotating the index finger toward the thumb. The switch 28 preferably includes a switch which will provide a click that can be felt by the user to provide tactile feedback so that the user is assured that the lap count has been entered or the timing function has been actuated. As shown in the drawings, the actuator is large and preferably a different color than the housing so that it can be easily located by the user. The device is shown in Figure 1(a) mounted on the right hand of the user, however, it may also be mounted on the left hand, with the switch 28 facing the thumb. Alternatively, if more comfortable to the user, the device may be mounted with the display facing underneath the hand, so long as the counter/timer is mounted with the actuator facing toward the thumb. While the device shown in Figures 1(a) and 1(b) are generally disk shaped, where drag is extremely important, for example in swimming, a more streamlined shape is preferred. As shown in Figures 1(c) and 1(d), preferably the top portion 19' is shaped to more nearly conform to the finger. The top should be somewhat oblong as shown in Figure 1(c), and concave as shown in Figure 1(d). The degree of curvature should not be too great so that the counter/timer can be utilized for a wide range of finger sizes. As shown in Figure 1(c), the counter/timer can optionally include additional switches 50,60 for controlling various functions of the device (discussed further hereinafter). The switches may be two or three position switches depending upon the number of functions, and actuation of the switches is not generally necessary during counting and timing of an event. The switches may include, for example, an operation mode switch and/or a display mode switch. An alarm in the form of a light 61 and/or buzzer 63 may optionally be provided to indicate that a predetermined distance or time has elapsed. Referring now to Figures 2(a)-2(c), various circuits for carrying out the functions of the device will now be described. The device can be constructed to perform a variety of functions. The following embodiments include both relatively simple, as well as more complicated embodiments. The more simplified versions can be produced for a lower priced market, or where the user does not desire the functions of the more complicated devices. Figure 2(a) depicts a more basic form of the present invention, in which a single function is provided. In particular, upon each actuation of the thumb switch shown schematically at 30, the counter 32 increases the status of the count by one, and the updated count is displayed by the read-out device or display 34. A single function timing device can also be provided in lieu of a counting device, with the counter 32 replaced by a timer, and switch 30 actuating the start and stop of the timer the display 34 displays the total elapsed time. The schematic representation of Figure 2(b) provides for a two function timer and counter. In the two function embodiment, the switch 130 actuates the timing and counting functions of counter 132 and timer 133, which are then displayed by read-out device 134. In the two function device, the first actuation of the switch 130 causes the counter to set to zero, and the timer to begin the timing operation. Successive actuations of the switch will then update the counter, but the elapsed time will continue, such that at the end of the event being timed, the display will read the totaled elapsed time, as well as the total laps (or distance increments) completed. To indicate that the event has completed, a quick double actuation of the switch 130 may be utilized to stop the timer, with the timer recognizing the quick double actuation as a stop signal, and the counter recognizing the quick double actuation as only a single count, such that the final double actuation serves to increase the counter by one, and also serves to stop the timer. Alternatively, an optional operational mode switch 131 (for example, as shown at 50 in Fig. 1(c)), may be utilized to stop the timing device. The operational mode switch may be turned to a read-only position upon completion of an event. Since there may be a slight time delay from the final actuation of the last count, to the time where the operational mode switch is changed to the read-only position (since the user must utilize their opposite hand for the operational mode switch), means may be provided such that movement of the mode switch to read-only causes the timer to revert back to the time of the last count. Thus, even though the timer continues to record time between the time of the last count and the time when the operational switch is in a read-only position, the timer can be reset to accurately display the elapsed time as of the last count actuation. If desired a calculating device or processing unit 135 may optionally be provided to produce calculated data, for example, the average per lap time. The user may switch from a total elapsed time display to an average time display by actuation of the thumb switch when mode switch 131 is in the read-only position. Thus, the mode switch 131 can also act to provide communication (as shown schematically at 136) between the thumb switch and display in the read-only mode, while allowing the thumb switch to control the counting and timing functions in the counting/timing mode. In yet another embodiment, a memory and computing device can be provided, such that the time for each lap, the average time per lap, as well as the total elapsed time, may be stored and read as desired. As shown in Fig. 2(c), the multiple function embodiment includes the switch actuator 230 which is actuated by the user's thumb to start the counting and timing operations. In addition, an operational mode switch 232 (which may be located as shown at 50, Fig. 1(c)) is provided for switching between data entry and data reading modes. As in the embodiment of Fig. 2b, timing and counting devices are provided as shown at 234, 236, respectively. In addition, a memory 238 is provided for storing information relating to the particular lap counts, such that when the operational mode switch is in the data entry mode, each actuation of the switch 230 causes entry of time data for the lap completed. Conversely, when the operational mode switch 232 is in the read-out mode, each actuation of the switch 230 causes a read out of the data entered for the particular lap, with information for the successive laps read out by successive actuations of the switch 230. A display mode switch 240 (which may be located as shown at 60, Fig. 1(c)) may also be optionally provided to select information displayed at 244, for example, where different time information is stored in the memory 238. In addition, a calculating device 242 may also be provided if desired to provide calculated data, such as an average time per lap. In operation, the user switches the operational mode switch to the data entry position, and the user actuates switch 230 at the beginning of the event. The first actuation starts the timer 234, and also produces an initial lap count of zero. Each successive actuation of switch 230 causes an updating of the counter 236 by one, and also causes storage of the corresponding time for the updated lap count. Upon completion of the event, a quick double actuation of the switch 230, or a switching of the operational mode switch to the read position (as discussed above with reference to Fig. 2b) stops the timing device 234, with the final entry corresponding to the total elapsed time and the total laps completed. When the operational mode switch is in the read position, the user can then successively actuate the switch 230 and the stored elapsed time for each lap can be read, allowing the user to reflect upon their performance throughout a particular event. This allows an athlete to compare their time for various segments of an event with a desired pace time. This can be important, particularly in endurance events where the athlete desires to set a particular pace or to utilize various pace strategies for better performance in the event. If desired, utilizing the optional display mode switch, the timing means 234 may take the form of two timing devices, one of which is reset upon each actuation of switch 230 (i.e., when the operational mode switch is in the data entry position), while the other maintains a total elapsed time throughout the event. The display mode switch is shiftable between a total elapsed time position, and a lap time position. In the total elapsed time position, the elapsed time for the total event will be read, while in the lap time mode, the elapsed time for each lap will be displayed. Thus, during an event, with the operational mode switch in the entry position, the user can either display the total elapsed time, or the time for a particular lap. This is particularly useful where an athlete desires to gauge their pace at a particular time during an event, so that the athlete can better estimate whether they are taking a faster than desired pace (which may result in premature fatigue) or an undesirably slow pace (which may result in an unsatisfactory overall time). Upon completion of the event, with the operational mode switch in the read-out mode, successive actuations of the thumb switch 230 will allow the user to read out either the total elapsed time for each successive lap, or the per lap time for each successive lap, with the selection of either the elapsed time or per lap time chosen by the position of the display mode switch. In lieu of the use of two timers in the timing means 234, a calculating device 242 may be provided, such that either the total elapsed time or the per lap time is calculated. Thus, the total elapsed time may be calculated by summing the previous stored values for the per lap time of the preceding laps. Alternatively, the per lap time may be calculated by subtracting the total elapsed time at the completion of each lap from the total elapsed time at the preceding lap. Each of the elapsed time and the per lap time is stored in the memory for each corresponding lap, with the time value read out according to the position of the display mode switch 242. If desired, the display mode switch may include a third position for average time, with the calculating means 242 dividing the total elapsed time by the total number of laps, such that the average per lap time at each lap is stored in the memory, and may be displayed when the display mode switch is in the average elapsed time position. Thus, the user can display the average time for the first five laps, for example, or for the entire event by actuating switch 230 until the lap display displays the desired number of laps for which averaged information is desired. Alternately, if it is not desired to have a per lap average at various intervals throughout the event, the calculating means 242 may perform a single average after completion of the event, such that only a single time per lap average is calculated for the entire event. In this variation, a separate position for the display mode is not necessary, and the average per lap time can simply be displayed as an additional read-out after the information for the successive laps has been displayed. For example, during read-out of an event which included five laps, after actuation of the switch 230 to display information relating to the fifth lap, a further actuation of the switch 230 can display the average time per lap data for the entire event. If desired, the operational mode switch may also be utilized as a reset switch, with the return of the operational mode switch from the read-out position to the data entry position clearing the memory, such that the counter begins at zero. However, the operational mode switch may also be provided with a separate reset position, such that the operational mode switch can be switched from the read out position to the data entry position, without erasing previously stored data. This is particularly advantageous where a successive number of athletes are to be timed, or where an athlete is running successive timed heats. Thus, successive heats for an athlete or successive athletes may be timed and compared. If desired, means may also be provided to allow the user to avoid successive actuation of the switch through each lap during the data reading mode, such that the user may skip the information relating to successive laps and may go directly to the information relating to the total event (either in the form of a total elapsed time, or the average time for all laps). This can be accomplished either utilizing a quick double actuation of the switch 230 when the operational mode switch is in the read-out mode, or utilizing a separate position of the display mode switch which can provide information totals. As a further optional feature, an alarm function may be provided as shown at 243. The alarm (for example, light 61 and/or buzzer 63 as shown in Figure 1(c)) can provide the user with an indication that a predetermined distance (number of laps) or a predetermined time has elapsed. This can be advantageously utilized to indicate the end of an event or to indicate when a predetermined portion of the event remains. For example, if a swimmer is training or competing in an event of 60 laps, the alarm can be actuated at 58 laps to allow the user to make a final sprint to the finish. The alarm can be actuated by the processing device 242, which will perform a test upon each actuation of the thumb switch to determine whether the current count or time equals a preset alarm count or time stored in the memory 238. The preset alarm count can be stored in the memory by positioning the operation mode switch in an "alarm set" position, at which time the thumb switch, or a separate alarm set switch is utilized to set a desired alarm count or time. The stored alarm data can be read at the display when the operation mode switch is in the alarm set position. The alarm thus provides an indication that a predetermined portion of the event remains, or that the event is completed. After actuation of the alarm, the alarm may continue to sound or stay lit until either the next actuation of the thumb switch, or until the event has been completed (which may be indicated by shifting of the operation mode switch to a read only position, for example). The present invention provides a convenient counting and/or timing device which can be easily actuated by an athlete without disturbing performance. The counter/timer can be worn on either hand and on a wide range of finger sizes without requiring special sizings, or individual modification. In addition the device is readily usable for a wide variety of sports, and adaptations for various sports are not necessary. While various forms of the present invention have been described, the present invention should not be limited to the disclosed embodiments as other modifications are within the scope of the invention. For example, if desired, a sensing device may also be provided to sense the pulse count of the athlete. This may take the form of a sensor located on the counter/timer, or a remote sensor which communicates with the timer/counter, for example by radio waves. Sensing of the athlete's temperature or the ambient temperature may also be provided. Thus, the present invention should only be construed as limited by the following claims.
