Definitions

  • the present invention relates to a shoe or boot which is provided in its inside portion with tank chambers which are filled with air, supporting and protecting a human foot from shocks imposed thereto.
  • Shoes have been proposed which are provided with a sensor for counting the number of steps taken by a user during walking or jogging to accumulate and indicate the number of steps taken within a certain time interval. Such shoes are disclosed, for example, in U.S. Pat. Nos. 4,651,446, 4,649,552, 4,578,769 and 4,571,680.
  • pump shoes In sports, athlete's weight abruptly imposed to his foot could often be a cause of an injured foot.

  • air pressure within the air chambers is adjustable, it will be convenient for the user to obtain preferable cushion and fitness for his feet.
  • the user is required to determined the air pressure within the air chambers with his sense. Therefore, the user sometimes fills the air chambers with air excessively and has to release air from the air chambers to obtain proper air pressure, and on the contrary he releases air excessively from the air chambers and has to supply air into the air chambers again. In this manner, a time consuming and troublesome work is required to adjust air pressure within the air chambers to a level that is appropriate for the user.
  • the present invention has been made in the light of the above mentioned situations and has an object of providing shoes or boots provided with tank chambers, within p62 which air pressure can be easily adjusted to a proper level.
  • Another object of the invention is to provide shoes or boots provided with tank chambers for measuring an amount and hardness of exercise having been conducted by the user and for protecting his feet as well.
  • a footwear comprises a tank member disposed to be in contact with the foot of a user, for applying pressure thereto; air pumping means for filling said tank member with air; pressure measuring means for measuring air pressure within said tank member to generate a pressure signal, said tank member being filled with air supplied from said air pumping means; and pressure data indicating means for indicating pressure data on the basis of the pressure signal generated by said pressure measuring means.
  • the above foot wear such as shoe or boot according to the invention allows the user to easily adjust air pressure within the tank chamber to obtain cushion and fitness comfortable for him. Once he has adjusted air pressure to a certain level such that comfortable cushion and appropriate fitness for him are provided, and memories the level of such air pressure, then he can easily obtain proper cushion and fitness thereafter by supplying air into the tank chamber until the indicating means indicates such level of air pressure.
  • Fig. 1 is a view showing the external appearance of the first embodiment of the invention, i.e., the external appearance of the shoe provided with tank chambers according to the invention
  • Fig. 2 is a perspective side-view of the shoe shown in Fig. 1
  • Fig. 3 is a cross sectional view of the shoe taken along the line A - A of Fig. 2.

  • the shoe is provided with air tank chambers 5A, 5B and 5C in its instep 1, shoe bottom and in a part surrounding a human ankle respectively, as shown by broken lines.
  • These air tank chambers 5A, 5B and 5C are connected with each other, forming a single air tank 5.
  • the air tank 5 serves to lighten shocks imposed to the foot of a user and serves to support his instep and ankle as well.
  • These air tank chambers 5A, 5B and 5C are made of gum, airtight flexible synthetic resin or airtight sheet.
  • the shoe is provided in its tongue 2 with an air pump 6 for supplying air to the air tank 5 and a pressure meter device 7 for measuring air pressure within the air tank 5.
  • the air pump 6 and pressure meter device 7 are connected with air tank 5 through air pipes 8A and 8B. Air is led from the air pump 6 to the air tank 5 through the air pipe 8A and further air is led from the air tank 5 to the pressure meter device 7 for measurement through the air pipe 8B.
  • Fig. 4 is a view showing the external appearance of the pressure meter device 7 and its circuit diagram is shown in Fig. 5.
  • a liquid crystal display unit 11 on the side of the pressure meter device 7.
  • the liquid crystal display unit 11 has a pressure indicating section 12 including ten bar-indicating members.
  • the liquid crystal display unit 11 indicates air pressure in a ten-level fashion with its turned on bar-indicating members.
  • a time indicating section 13 At the lower side to the pressure indicating section 12, there is provided a time indicating section 13, which indicates a present time counted by CPU 14, as will be described below.
  • the pressure meter device 7 is provided with three switches S1, S2 and S3.
  • the switch S1 is operated for measuring air pressure, and the switches S2 and S3 are operated for correcting time data.
  • CPU 14 stands for a central processing unit, which controls operation for time counting, measurement of air pressure within the air tank 5, and indication of time and air pressure.
  • CPU 14 supplies an open signal SA for opening an air valve 16 to an open/close driving section 15 and at the same time supplies a driving signal SB to a pressure sensor 17 including a semi-conductor pressure sensor and to A/D converter 18.
  • the air valve 16 is connected with the above air pipe 8B and the pressure sensor 17. When the air valve 16 is made open air in the air tank 5 is led to the pressure sensor unit 17, allowing the pressure sensor unit 17 to measure air pressure within the air tank 5.
  • CPU 14 is supplied with a clock signal and a timing signal each having a certain period from an oscillation circuit (OSC) 19.
  • OSC oscillation circuit
  • CPU 14 performs various processes in synchronism with the clock signal supplied thereto. More specifically, CPU 14 performs such processes as a process for supplying signals SA and SB in response to operation of the switch S1, a process for causing the pressure indicating section 12 to indicate measured air pressure and a process for counting a present time at a certain time interval.
  • CPU 14, the pressure sensor unit 17 and A/D converter 18 are supplied with a driving voltage from a battery 20.
  • the user puts his foot into the shoe and pulls up the tongue 2 to operate the switch S1, allowing the measurement of air pressure to start. Then, the user depresses the air pump 6 to fill the air tank 5 with air through the air pipe 8A. Since the air tank chambers 5A, 5B and 5C supporting the foot of the user are connected with each other through pipes, tubes and the like, all of these air tank chambers expand as the air pump 6 works.
  • Air in the air tank 5 is led to the air valve 16 of the pressure meter device 7 through the air pipe 8B. Since, at this time, the air valve 16 is made open by the open/close driving section 15, air in the air tank 5 is further led to the pressure sensor unit 17 through the air valve 16, allowing the pressure sensor unit 17 to measure air pressure. An analog value of air pressure detected by the pressure sensor unit 17 is converted into a digital value by A/D converter 18, and the value of air pressure is indicated in a ten-level fashion on the pressure indicating section 12.
  • the user of the shoes gradually pumps air into the air tank 5, watching the indication on the pressure indicating section 12 until desired cushion and fitness are obtained. If he should have pumped air too much into the air tank 5, he can adjust the air pressure within the air tank 5 by opening a release valve (not shown) so as to gradually release air from the air tank 5.
  • the indication on the pressure indicating section 12 allows the user to adjust in a short time the air pressure within the air tank at a proper level since he neither pumps nor releases air from the air tank excessively or deficiently as he does while he pumps air by feeling air pressure imposed on his foot.
  • Figs. 6 and 7 are views showing an external appearance of a pressure meter device 21 used in the second embodiment and its circuit diagram, respectively.

  • the pressure meter device 21 is further provided with a dot-matrix display section 22 for indicating a measured pressure data, a stored pressure data and a present time.
  • CPU 23 is a central processing unit, which stores a micro program, and performs a time counting process, a measurement process of air pressure within the air tank 5, an indication process of indicating a time and air pressure, and a process of storing a present time and measured pressure data in RAM 24 in accordance with the micro program.
  • a mode register M serves to indicate an operation mode. More specifically, when a time indication mode has been set, a value "0" is set to the mode register M, and when a pressure measurement mode has been set, a value "1" is set to the mode register M.
  • a time counting register T serves to store a present time counted by CPU 23.
  • a register C is a timer register that counts time intervals for measuring pressure.
  • Registers D0 and D1 serve to store a presently measured pressure data and previously measured pressure data, respectively.

  • An indication register A serves to store data to be indicated on the dot matrix display section 22, i.e., it stores data transferred from the time counting register T and the pressure data memory S.
  • a buzzer 25 gives the audible alarms in two ways during adjustment of air pressure, one when the air pressure is increasing and other when the air pressure is decreasing.
  • CPU 23 usually remains in a halt state at step S1 of Fig. 9. Every receipt of a time counting signal of one second generated by the oscillator 19, CPU 23 goes to step S2, where it judges if the mode register M has been set to a value "1".
  • step S3 a present time in the time counting register T is updated.
  • the present time processed in the indication process is indicated at step S4.
  • FIG. 12A An example of the indication in the time indication mode is shown in Fig. 12A, and date/present time data "3:56:45 September 23" is indicated on the dot matrix display section 22.
  • step S5 When operation of any one of switches 11 to 13 is detected while CPU 23 is in the halt state at step S1 of Fig. 9, the operation goes to step S5, where it is judged if the operated switch is S11.

  • step S22 presently measured pressure data is stored in the register D0.
  • Pressure data of the register D0 is compared with pressure data of the register D1 at step S23.
  • D0 ⁇ D1 is true, i.e., when pressure is decreasing, the operation goes to step 24, where an alarm-1 process is performed, causing the buzzer 25 to generate a predetermined alarm sound.
  • step S13 when it is judged that the switch other than the switch S11 has been operated, the operation goes to step S13, where it is judged if the switch S12 has been operated.
  • Fig. 12B is a view showing an example of the indication on the dot matrix display section 22.
  • the pressure data "1.76 Kg" stored in the pressure data memory S is indicated and on the lower half portion measured pressure data "1.34Kg" of the register D0 is indicated.
  • the user can easily adjust air pressure to his desired pressure level, watching the indication on the display section 22 because presently measured air pressure data, for example, "1.34 Kg" and the most suitable air pressure as well, for example, "1.76 Kg" stored in the pressure data memory S are indicated on the display section 22 at the same time. Therefore, the user is not required to feel pressure within the air tank 5 with his foot to make a fine adjustment of air pressure therein each time air escapes from the air tank 5. Once adjustment of air pressure has been made, the user can easily adjust thereafter the air pressure for his desired cushion and fitness.
  • step S5 of Fig. 9 When the switch S11 is operated again after air pressure was adjusted as described above and the adjusted air pressure was stored in the pressure data memory S, it is judged at step S5 of Fig. 9 that the switch S11 has been operated, i.e., the result of the judgment at step S5 is "YES”, and it is judged at step S6 that the mode register M has not been set to a value "0", i.e., the result of the judgment at step S6 is "NO”. Then, the operation goes to step S16, where CPU 23 instructs the open/close driving section 15 to make the air valve 16 close.
  • step S17 the power supply to the sensor unit 17 and A/D converter 18 is made off and the measurement of air pressure is finished. Thereafter, the registers D0 and D1 are cleared, and a value "0" is set to the mode register M and thereby the time indication mode is set.

Then, the operation goes to step S19, where a selection process for selecting a digit of the time data to be corrected is performed.

More specifically, since the pressure data of 1.5 times the most suitable pressure data or higher is not always the highest pressure data at step taken by the athlete, the pressure data obtained within the time interval of 0.5 sec. are compared with each other to detect the highest pressure data among them.
  • step B8 it is judged what time within the time interval of 0.5 sec. the detected highest pressure data has been detected, and time data representative of time lapses between steps stored in the register C is corrected. Now, the highest pressure data and time data stored in the register C are written as "data for the first step" into an exercise data memory 47a of RAM 47.
  • step B9 a value "0" is written into the registers C, S and L and thereby these registers are cleared, and the operation goes to step B13. Similarly, address is updated at step B13, and when it is judged at step B14 that the trailing address is not reached, the operation returns to step B2.
  • step B2 pressure data is read out from RAM 48 in accordance with the designation of the pointer P, and the register C is incremented by "+1" at step B3.
  • pressure data (for the second step) of 1.5 times the most suitable pressure data or higher is read out from RAM 48, it is judged as "YES” at step B10 and the operation goes to steps B11 and B12. Similarly, pressure data obtained in the time interval of 0.5 sec. are temporarily stored in the work area until it is judged as "YES” at step B6. At step B7, the highest pressure data for the second step of the athlete is detected. At step B8, time data of the register C is corrected, and the highest pressure data and the corrected time data are written into the exercise data memory 47a of RAM 47 as "data for the second step".
  • the address pointer P of RAM 47 is updated every operation of the switch S4, and the pressure data "3.45 Kg" for the first step is read out from the exercise data memory 47a and is indicated as shown at F of Fig. 22.
  • the pressure data "3.56 Kg" for the second step and time data "0.63 sec.” representative of a time lapse between the first and second step are shown at A of Fig. 23.
  • Another operation of the switch S4 allows the pressure data "2.97 (Kg)" and time data "0 (sec.)" for the first step of the second trial stored in the exercise data memory 47a of RAM 47 to be indicated.
  • the most suitable pressure data can be easily set, but also exercise data and time data can be measured with reference to the previously set most suitable pressure data.
  • time data representative of a time lapse between steps taken by the athlete and pressure data at each step taken by the athlete are measured, but the third embodiment may be used as a pedometer, as shown in Figs. 24 and 25, for measuring amount of exercise conducted by the user such as the number of steps taken by him and the approximate distance he walks.
  • Fig. 24 is a view showing the construction of RAM 60 which is used in place of RAM 47 of Fig. 18.
  • RAM 60 comprises an indication register, a register D0 for storing measured pressure data, a register D1 for storing a set most suitable pressure data and a register R for storing step-number data.
  • the indication register, register D0 and register D1 are the same as those of RAM 47.
  • the number of steps taken by the user is measured in the process shown in Fig. 25. More specifically, the process of Fig. 25 is performed every one 16th seconds to measure the number of steps.
  • the process at step G1 is for measuring pressure within the tank chambers, and measured pressure data is stored in the register D0.
  • step G2 it is judged if the pressure data stored in the register D0 is equivalent to 1.5 times the most suitable pressure data or higher.
  • the operation goes to step G3, where a value "2" is added to the step-number data stored in the register R.
  • step G4 a process is performed for suspending measurement of pressure for a certain period, for instance, for a period of 0.5 sec. More specifically, once it has been judged that the pressure data stored in the register D0 is equivalent to 1.5 times the most suitable pressure data or higher, the pressure data which is detected within a certain period thereafter and which is 1.5 times the most suitable pressure data or higher is deemed and processed as pressure data for the same step taken by the user.
  • step G5 the step-number data stored in the register R is indicated as data representative of amount of exercise.
  • the embodiments of the invention may be provided with an operation circuit, and data such as the user's weight, age and sex in addition to the step-number data are entered into the operation circuit by key operation.
  • the operation circuit may calculate consumed calorie using these entered data.
  • the calculated consumed calorie may be indicated as data representative of amount of exercise.
  • a pace and step-number data may be entered to the operation circuit for calculating a distance he walked.
  • the calculated distance may be indicated as data representative of amount of exercise.
  • a walking velocity may be indicated as data representative of amount of exercise conducted by the user.
  • various data representative of amount of exercise conducted by the user may be obtained by measurement of pressure imposed on the user's foot.
  • these data may be data representative of hardness of exercise or aerobics points.
  • the invention shall not be limited to the particular details of the construction of the above embodiments.
  • gas filled into the tank chambers of the footwear is not always air but other gas such as carbon dioxide gas may be used.
  • the construction of the tank chambers and tubes connecting the tank chambers shall not be limited to that of the embodiments. Further, the disposition of the air pump and pressure meter device within the footwear shall not be limited to that in the embodiments.
  • Modification may be made such that the air pump is not mounted inside the footwear but only the inlet valve member is mounted to permit air to be pumped thereto from an external air pump. Further, the inlet valve member is mounted on the footwear but the pressure meter device may be detachably mounted on it only while the user conducts an exercise or air is pumped thereto.
  • the measured pressure data and the stored most suitable pressure data may be indicated in a digital fashion or in an analog fashion as well.
