System for sports training

BACKGROUND OF THE INVENTION

1. Field of the invention

The invention relates to a sports training system for athletes, comprising at least: a fender device with fender, electronic fender sensor means cooperating with the fender device and electronic fender force evaluation means electrically connected to the fender sensor means provided with an electronic display screen.

Such systems are used in sports training of various kinds, in particular in boxing training, but also for training in the field of physical therapy, martial arts, football, police training for the use of a baton, etc.

2. Description of the related art

A system of this kind is known, for example, under the trade name PowR-Pad® * and is marketed by Adepta Sport Technologies Ine., A company with an office in Kendall Park, New Jersey, USA. The known system comprises so-called "impact pads" which can be held by a trainer and against which, for example, a boxer can bump. In the PowR-Pad Pro ™, battery-powered impact sensor means and impact evaluation means connected to the fender are provided, and there is a display screen on the back, which is thus facing the trainer, on which the digital display of a value in a "Force" mode in lbs. can be shown from a focused forward shot. In a "Response" mode, the reaction time of the athlete can be displayed after a random auditory indication.

In the aforementioned system according to the known I

There are a number of disadvantages: I

The impact force is only measured in a single I

direction so that the total impact force, which almost always exists I

5 from multiple impact force components in multiple directions, I

cannot be accurately determined. Only the impact I

measured perpendicular to the front face. I

The magnitude of the measured impact force value is dependent

depending on the person holding the PowR-Pad cushion, I

The results of a training session cannot be I

stored so that it is difficult to monitor I

3 • Ft is the value of the vectorial sum of the three impact components and • x, y and z are respectively the said components in the X, Y and Z directions.

A first embodiment of the invention is defined in claim 2. This embodiment is particularly suitable, because of the special shape of the fender unit, to be able to absorb impact forces exerted from different directions. In boxing, for example, it is important to be able to practice 10 punches in the directions from front to back, from left to right, from right to left and from bottom to top. The elastomeric coupling elements used are advantageous because they have a certain internal damping, which benefits the dynamic behavior of the fender device. The structure is such that the buffer carrier is supported by the elastomeric coupling elements so that it is slightly movable relative to the base. With the at least one acceleration sensor unit, the components of the acceleration are measured from the fender support according to the three coordinate axes relative to the substantially stationary base. Due to dual integration, the displacements can be calculated and the impact forces exerted on this basis.

The system is preferably designed according to claim 3. This embodiment provides favorable ergonomic properties coupled with a logical and simple arrangement of the elastomeric coupling elements. The diabolo-shaped spring elements used for this purpose are generally known and are easily available on the market at a favorable price. This type of spring element is in fact generally used with sailboards for coupling the mast to the plank.

It has been found that an embodiment of the invention according to claim 4 is favorable. Acceleration sensors that are sensitive to only a single direction are relatively inexpensive and this certainly also applies to the required signal amplifiers. Furthermore, the achievable resolution and the necessary measuring range are sufficient. A major advantage of an acceleration sensor is also that the sensor only needs to be mechanically connected to the moving part of the system, that is to say the cushion carrier, in order to nevertheless transfer the displacement.

of these that are decisive for the impact I

to be able to measure forces relative to the base. Because I

the sensor units need only be mechanically connected

With the fender unit, the assembly of the pad is I

5 very facilitated. I

A further embodiment is characterized by I

claim 5. In this embodiment, the cushioning pad I

as a wall, in placement height adapted to the posture I

10 from the athlete, so that you can train without the help of I

a trainer or other employee for holding the I

pad assembly. I

The embodiment according to claim 1 is also advantageous

6. Because of this embodiment, there is more freedom with regard to I

15 to the place where the pad assembly is stationary I

is prepared. I

Preferably, an embodiment of the invention is used

the evaluation means can easily be at some distance from I

20, the fender assembly can be arranged and the coupling I

between the electrical / electronic part and the mechanical I

part of the system can be created as desired I

or be detached. I

The versatility of the system is also preferably used

25 is increased by using an embodiment I

according to claim 8. In this embodiment, cushioning I

units with different pad properties are I

used that can be adapted to the requirements of ver

different sports, but also within a certain sport on the I

30 requirements of different groups of athletes, for example af

depending on age, sex, training, physical strength, I

etc. I

5, a description thereof will follow later in the context of the figure description.

Very interesting is an embodiment according to claim 11. This embodiment makes it possible to measure both the reaction time and the force per type of impact and to analyze it afterwards. It is also possible to conduct a training session again at a later time and to compare it with a previous training session. This way you can follow the development of the athlete's training condition over time. The time that elapses between the indication and the athlete's reaction in the form of a bump against the pad can be accurately measured and recorded.

Use is preferably made of the embodiment of claim 12. The indication means indicate, under control of the computer, optionally with the aid of a random function, in a visual or auditory manner when a response is expected from the athlete. This makes it possible not only to indicate to the athlete that a reaction is expected, but also that a certain type of punch is expected as a reaction, which is of importance in particular for boxing training.

An interesting extension of the functionality of the system according to the invention is provided by claim 13. In the system according to this embodiment, a complete pre-programmed boxing round can be performed by a boxer, the results of which can be analyzed afterwards.

A system according to claim 14 has been found to be very favorable, wherein the boxer is indicated in an easily understandable visual manner what type of punch is expected.

In the figures, the same parts are indicated with the same reference numbers. The figures are drawn on a random scale and not always on the same scale.

FIG. 1 shows a system according to the invention which is primarily intended for the boxing training of boxers. The system comprises a fender device 1 provided with a fender 3. The electronic fender sensor means cooperating with the fender device consist of sensor units, one of which is shown with the general reference number 5 in FIG. 7.

The impact sensor means, which, as stated, comprises three sensor units of the ones shown in FIG. 7 are adapted to detect three impact force acceleration components according to three mutually perpendicular coordinate axes X, Y, Z (see Figs. 4 and 6). The impact force evaluation means 7 is adapted to evaluate each of the three mentioned impact acceleration components and the display means 9 are arranged to display the value of at least the vectorial sum of the three impact force components or, in other words, of the total applied force . If desired, the three components could also be displayed separately.

In the present embodiment of the invention, the impact force evaluation means comprise computer means in the form of a PC (Personal Computer) 11 and the display means 9 consist of a display tube monitor coupled to the computer 11 and provided with a display screen 13.

The various parts of the pad device 1 will first be discussed below.

The fender unit comprises a fender assembly consisting of a fender unit 17, a base 21, a number of coupling elements 23 (see Fig. 2) and the sensor means 5.1 to 5.3. In the embodiment of the invention, the fender assembly is mounted on a displaceable support structure 25, to be described later, on which it can be adjusted in height. The fender 3 of the fender unit 17 is made of conventional foamed material and provided with a coating in the form of a suitable rigid foil, for example from a textile reinforced with textile. Such types of pads are, as previously stated, 1024523

FIG. 3 shows the general structure of the base 21. This consists essentially of a base plate 49, four side walls of equal length and height 51, four identical support brackets 53 placed in the corners and a number of fixing eyes 55, namely three on each side, three of which are shown in Figs. 3 are visible. The base 21 thus forms a square container which is preferably made from a sturdy metal such as steel or aluminum. Near each corner of the base 21 there are mounting holes for mounting spring elements 23, namely a hole 57 in the support brackets 53 and holes 59 in each of the side walls 5i connecting to the support bracket 53. Bolts are inserted through these holes, such as bolts 61, two of which are designated by reference numerals 61 in FIG. 5 and 15 are screwed into a threaded hole 47 of the end plate 43 of a spring element 23. The axes of the various spring elements thus connected to the base 21 are always oriented in accordance with the coordinate axes X, Y and Z, with each set of three spring elements present at an angle of the base 21, in each case one of the center lines is oriented along the x-axis, another according to the y-axis and the remaining other according to the z-axis. The entire arrangement is, as in FIG. 5 can be clearly seen, symmetrical with respect to the center of the base 21. Thus, three sets of four spring elements 23 are formed which are distributed over the four corners of the cushion support 19 and the base 21 with near each of the corners of the base buffer carrier 19 and base 21, respectively, three spring elements are arranged, one of each of the three sets mentioned. The center lines 39 of the spring elements 23 which belong to the same set run parallel to each other, i.e. parallel to the x-axis, the y-axis or the z-axis. The center lines 39 of the three sets are therefore mutually perpendicular to each other and perpendicular to the cushion support 19 and the base 21, parallel to side walls of the cushion support 19 and the base 21 and parallel to the front and rear walls of the cushion support, respectively the base.

FIG. 4 shows a bottom view of the buffer carrier 19. The buffer carrier comprises a base plate 63, left 40 and right side walls 65L and 65R and a front wall 65V and a 1024523

10 I

rear wall 65A. Fastening elements I are provided on the base plate 63

67 fixed, for example welded, each provided with two I

upright parts 69 perpendicular to each other and provided with I

a hole 71. These fixing elements 67 are positioned in this way and I

5 arranged that they can cooperate with the end plates 43 of I

associated spring elements 45, wherein the holes 71 serve for I

piercing bolts 61 which engage in the screw I

threaded holes 47 of the associated end plates 43 of the respective I

spring elements 45. It should be noted that in I

spring elements 23 are mounted in reverse position over the base 21

and the bolts 61 pass through the respective side walls I

51L, 5IR and the front and rear walls 51V and I respectively

IA is arranged in the screw thread holes 47 of the previously I

spring elements 23 mounted on the base plate 19. In the base I

there are holes 73 on the plate 63 of the cushion support that I

projecting above the vertically positioned spring elements 23 I

and through which the bolts can be inserted for cooperation I

25 with the respective threaded holes 47. Thus, a fast I

once again shows the mounted condition, with the base plate I

19 with broken lines if transparent is shown around I

30 also to show the parts that are present between the bump I

cushion carrier 19 and the base 21.

The impact sensor means, see in particular Figs. 4, includes I

three separate capacitive acceleration sensor units 5.1, I

5.2 and 5.3, one for each of the three perpendicular to each other I

35 coordinate axes x, y and z. Each of these acceleration I

sensing sensor units is of the general type of the shock I

sorm means 5 shown in FIG. 7. This is a capacitance

selective acceleration sensor with a high overload resistance I

with integrated electronics for the dynamic measurement of

40 speeds in the frequency range from 1 Hz to several I

1 024523-1

11 kHz. The shock sensor means used are, for example, of the BDK100 type, available from SEIKA Mikrosystemtechnik GmbH in Kempten in Germany. This kind of capacitive shock sensor means has a measuring range of up to about 100 g with a resolution smaller than 5 x 10 12 g in a frequency range of 1 to 1500 Hz. The sensitivity is approximately 15 mV / g. The acceleration sensor units include, as shown in FIG. 7, a housing 75 with a diameter of 21.5 mm, a hexagonal base 77 with a key width of 22 and a threaded piece 79 provided with thread M6. At the top comes from the housing 75 a connecting wire 81 for the electrical connection to the evaluation means.

In the center of the base plate 63 of the cushion support 19, see FIG. 4, a hole (not visible) is provided in the base plate for mounting the acceleration sensor unit 5.3. The hole in the base plate could be threaded and the relevant acceleration sensor unit could be screwed into the base plate 63. It is also possible to arrange a nut on the other side of the base plate 63 on the thread piece 79 of the relevant acceleration sensor unit. The two other acceleration sensor units 5.1 and 5.2 are mounted on a support element 83 which, like the support elements 67, is mounted on the base plate 63, for example by welding or soldering. The supporting element 83 comprises two upright parts 85 oriented perpendicular to each other and perpendicular to the base plate 63, to which the acceleration sensor units 5.1 and 5.2 are mounted in a manner similar to the manner in which the acceleration sensor element 5.3 is mounted on the base plate 63. The connecting wires of the various acceleration sensor elements are connected in an appropriate manner to other elements that may or may not be present within the fender assembly 15.

The supporting structure 25 of the fender device 35 1, see Figs. 1, comprises a simple frame assembled from profiles, for example by welding or soldering, comprising the upright part 33, a horizontal base frame 85 on which the upright part 33 is mounted on the underside, and two slanting braces 87 between the rear side of 40 the base frame 85 and the top of the standing part 33. The

12 I

standing part 33 comprises two vertical posts 89L and 89R that I

are connected to each other at the top by a cross piece I

91. The fender assembly 15 is in the vertical direction at I

mounted mounting frame 93, provided on either side with I

95L and 95R rails running vertically. In FIG. 8 I

a partial cross-section on an enlarged scale is made

through such a rail. The rail 95 consists of an on I

15 the tubular profile of approximately rectangular through-open through the front

section within which there is a smaller box profile 97 of also I

rectangular section that is within the profile 95 on and I

can move down. To absorb shocks and for a good I

20 up and down can be guaranteed on the tubular section 97 I

blocks 99 and 101 placed with a more or less self-lubricating I

surface, for example from Teflon. The pad assembly I

Due to the described mechanical construction, an I

pad device can be obtained with good damping requirement

properties coupled with a very simple and also economical I

favorable construction, by using the diabolo-shaped, I

35 coupling elements or spring elements made of elastomer

23. FIG. 9 shows the response of an acceleration sensor

sor according to FIG. 7 with an impact exerted on the cushion I

3. The impact force on the vertical axis is determined by an arbi

linear scale, while on the horizontal axis the time I

40 is indicated in milliseconds. The figure shows I

1024523-1

13 that the signal 103 is almost completely muted within a time frame of about 100 milliseconds. The noise on the signal comes from all kinds of environmental influences such as vibrations in the floor, etc.

After the description of the mechanical part of the shown embodiment of the system according to the invention, short attention will now be paid to the electrical part. For this, reference is made to the block diagram of FIG. 10.

Since the personal computer 11 must process the measurement data 10 from the acceleration sensor units, the signal from the acceleration sensor units must be digitized. For this purpose the circuit of FIG.

10 used.

Before the total impact force can be determined from the signals emitted by the sensors, these signals must first be conditioned. To this end, all three sensor signals, i.e. for the X, Y and Z directions respectively, are subjected to analog and subsequently digital conditioning. For a discussion of the processing steps used herein, reference is made to the block diagrams of the used processing circuits of FIG. 10A, B. FIG. 10A relates to the processing of a single sensor signal from a single acceleration sensor. A separate identical processing circuit is provided for each of the three acceleration sensors, so only a single circuit will suffice.

In a first processing step in the analog decoupling block 147, the analog sensor signal is decoupled. Hereby is achieved that the direct voltage level U2 (S of 2.5V 30 of the raw sensor data is lowered to the ground reference level U0. The following next steps concern amplification in the analog amplifier block 149 and filtering in the analog filter block 151 of the analog signal so that the amplitude of the signal rises to U a and interference is filtered out. The resulting analog signal is indicated by ü. The filter block 151 comprises a 2-pole Butterworth low-pass filter with a cut-off frequency of 50 Hz.

After the filtering operation in the filter block 151, the quality of the analog signal U £ is good enough to be digitized in a 10-40 bit analog to digital converter, the block 153, 1024523

14 I

turn into. The resulting digital signal D is applied I

to a software filter block 155 to convert any present

filtering error errors from the digital signal D and to

filtering out the interference, the resulting digital I

5 signal is Df. Again, use is made of a 2- I

pole Butterworth low-pass filter with a cut-off frequency I

of 50 Hz. The next step, in the digital peak detection block I

157, is to detect the peaks P in the signal Df. From I

these peaks are then entered in the digital calculation block I

10 159 a maximum impact I measured by the relevant sensor

force F calculated according to the formula I

Fi = m1 * a1 I

wherein: I

Ft the thrust is in Newton, I

15 mt is the mass of the fender unit consisting of the fender and the fender carrier

aA is the acceleration in m / sec3 corresponding to the I

highest peak of the measured acceleration, determined in I

block 157 and I

I consists of X, Y or ZI

From the forces calculated in this way, based on I

the three measured peak values of the accelerations in respective I

the X, Y and Z directions, thus the I respectively

FIG. 10B, the total force Ft calculated in the digital calculation

The described embodiment of the system according to the invention has yet another functionality, namely a reaction training session analysis function with one or more reaction training elements from the set: impact reaction time, maximum impact, maximum impact speed, maximum impact reaction time, minimum impact reaction time and average impact reaction time. The intention is for the system to be able to measure the reaction time of the boxer after a visible or audible indication that a reaction is required, while also indicating the type of punch expected from the boxer. The reaction time and the impact force are measured and recorded. To this end, the system is for instance provided with indication means for giving a visible and / or audible indication to the boxer 15 that a reaction of a certain type is expected.

An example of visible means that could be used is shown schematically in FIG. 13. FIG. 13 shows a schematic top view of the cushion 3 with the top surface 27, the rear surface 31A, the left side surface 29L, the right side surface 29R and the front surface 31V. A number of indicator lights, preferably consisting of LEDs, 121, 123, 125, 127, 129 and 131 are arranged around the cushion 3. Furthermore, a vertical center line 133 and a horizontal center line 135 are indicated in the figure. If the LED 121 lights up, a left-hand direct is expected from the boxer on the front surface 27 of the cushion. Similarly, the other LEDs indicate: 123 (right-hand direct), 125 (right-hand corner), 127 (right-hand ramp), 129 (left-hand ramp), 131 (left-hand angle), respectively. The different LEDs are arranged in a logical manner, that is, the LEDs 125 and 131 are located on the center line 135, while the LEDs 121 and 129 are to the left of the center line 133 and the LEDs 123 and 127 to the right thereof. The top surface 31A is not used in boxer training sessions. By switching on more than one LED at a time, or possibly all LEDs at the same time, an indication can be given to the boxer that a random punch is expected.

Another possibility would be, for example, to place an image on the top of the cushion assembly in front view 40 of the cushion and in this image with LE.1024523-

18 I

D's or something similar to indicate against which part of the I

pad the next punch is expected. I

To analyze the reaction training session, I

made use of the screen 145 displayed on the I

5 display screen 13 of the impact force evaluation means 7. With I

using this screen, both the response time and the I

force per impact type are analyzed after a reaction run

training session. At the top of the screen is a graphic

present of current reaction training elements. This I

10 can be adjusted with every shot so that the boker and / or the I

trainer can watch the session progress. In the part I

at the bottom left of the screen becomes a virtual pad 137 I

shown with an upper surface divided into a left-hand partial upper surface I

139L and a right-hand side upper surface 139R, a left-hand side surface 141L I

15 and a right side face 141R as well as a front face 143 which if desired

If desired, it can also be divided into a left-hand sub-plane and an I

right part plane. Is the display screen 13 in the I

field of view of the boxer engaged in the reaction training

session, the previously described indications for I

20 expected shocks are also indicated on the display screen I

for example, by color change of the relevant part I

of the virtual fender 137. The straight line in the screen 141 is I

a number of buttons not indicated by reference numbers

with which the session can be controlled. With the "se-I

Read session "a preprogrammed session can be set

selected. This can be started by pressing the "start session" button

". The boxer can then pre-program the box

session will be completed. I can complete a boxing round

be defined that includes a selected sequence of

30 punches from the aforementioned punch collection as well as an I

round start, a round end, a rest break start and an I

rest break end. Indicators may be present (not I

shown in the drawing), for example consisting of hearing I

possible indications for indicating the start of I

35 a round, the end of a round, a break and the end

from a rest break. I

The invention as explained with reference to the invention

The described embodiment provides a number of important I

advantages: I

The magnitude of the measured impact force value is independent of the placement and attachment of the impact sensor assembly, as long as the requirement is met that it is mounted on a sufficiently rigid substrate such as a brick wall or a suitable supporting structure.

The magnitude of the measured total impact force is independent of the direction in which the impact force is exerted on the fender because the force is measured in three mutually perpendicular directions.

The system according to the invention offers the possibility of displaying the impact force and / or reaction time of an almost unlimited number of shocks, possibly in a graphical representation as a function of time or, for example, in the form of a table. A causal relationship can thus be established between the elapsed time and the impact force and / or. reaction time at any time in time and the frequency of shocks over the aforementioned time interval can be recorded and displayed.

Measurements made in the past can be reconsidered at any later time, so that by comparison with recent training results the progress in the training results of the user can be evaluated.

Although by way of explanation only a preferred embodiment of the present invention has been described, it will be apparent to those skilled in the art that the present invention should not be considered in any way limited to the described preferred embodiment only. Various changes and modifications can be made within the spirit and scope of the present invention as defined in the following claims.
