Description

  The present invention provides a footwear having a switch capable of detecting an increase / decrease in foot pressure as an ON / OFF electric signal at a center point of the measurement point at a foot pressure sensing measurement point provided on the footwear base in a spot manner with an increase / decrease in load accompanying movement. Regarding the pedestal.

An insole sheet capable of recognizing an action while stimulating the sole by increasing or decreasing the foot pressure is disclosed in a gazette (Patent Document 1). Patent Document 1 discloses that the dome-shaped flexible member is a change in foot pressure, which gives the user a certain stimulus by the action of being deformed up and down, and the switch function is incorporated into the dome-shaped flexible member to change the foot pressure. It was an insole sheet to which the function of converting to an electrical signal was given.
Japanese Patent No. 4829257

When the dome spring is reversed and restored by foot pressure that changes according to the user's movement in the foot pressure measurement parts provided in spots on the footwear pedestal including the insole seat, the position of the center of gravity and electrical signal sensed by vibration sound What is needed is a way for the ON / OFF output signals to be tactile, auditory, and visual.
According to the experiment, it was found through the subjects that the actual feeling of depression and the feedback of the output electric signal were uncomfortable just by shifting by 0.1 seconds.

  The present invention has been made in consideration of the above points, and in order to detect a foot pressure that changes according to a user's movement, the flexible portion of the dome-type switch mechanism has a two-layer structure, and changes according to the increase or decrease of the foot pressure. By condensing and releasing the body fluid of skin cells into the vertical center line of the first layer, the top of the vertical center line of the second layer is accurately pushed in, and the electrical contact is accurately connected / cut off.

  The footwear pedestal according to the present invention has a built-in two-layer flexural acoustic switch mechanism, outputs the increase and decrease of foot pressure with ON and OFF electrical signals, and when the first layer of the double-layer flexural acoustic switch falls downward, As the dome spring of the second layer is pushed in and reversely restored, the flexure diaphragm is impacted and the vibration sound is amplified in the resonance space, giving a pleasant stimulus to the sole and simultaneously changing the load on the sole. The point can be detected acoustically.

  The footwear pedestal according to the present invention can take out a slight pressure change as an ON / OFF signal even with a switch mechanism that emphasizes the comfort in ordinary footwear.

  The foot pressure measuring unit according to the present invention catches a weak change in the initial foot pressure, which increases due to the user's movement, with a two-layer flexural acoustic switch and converts it into an ON / OFF electrical signal. Can be detected in real time by visualizing the position of the load change on the sole.

  The footwear pedestal according to the present invention has a dynamic feeling of foot pressure that changes with a change in motion and an electrical signal that is output ON / OFF on the dome spring center line of the two-layer flexural acoustic switch, The output timings of the ON / OFF signals match, and visual, auditory, and tactile stimuli can be perfectly matched. As a result, feedback to humans can be made immediately based on accurate sole position information. In other words, the information necessary for humans is sufficient (locations where pressure is applied) and their timing information, and the positional information generated when the dome spring reverses and restores resets the stimulus and sensory displacement as a result of movement. It becomes a body reset tool that can be greatly improved in the field of lifestyle or sports.

  Hereinafter, the best mode of the present invention will be described with reference to the drawings. However, such examples do not limit the technical scope of the present invention.

  FIG. 1 is a top view of a footwear base according to an embodiment of the present invention. The upper surface of the footwear base 1 may be covered with a footwear member such as a cloth, and FIG. 1 shows a right footwear base for a right foot. As shown in FIG. 1, the footwear base 1 includes a plurality of two-layer flexible acoustic switch units 2. The footwear pedestal 1 is a pedestal on which a sole of a footwear such as shoes, sandals, slippers, or socks is placed, is a component of footwear, and may be an independent article such as an insole sheet. A plurality of two-layer flexural acoustic switch units 2 provided on the footwear pedestal are arranged at a plurality of positions arranged at equal intervals from the heel to the toes at the passing point of the center of gravity movement in normal walking in order to sense foot pressure in a spot manner. The

  FIG. 2 is a cross-sectional view showing the configuration of the two-layer flexural acoustic switch unit 2. The two-layer flexural acoustic switch unit 2 is disposed in a recess provided in the footwear pedestal 1 and includes a flexure diaphragm 10, a dome spring 15, a conductive spacer 16, and an electrical contact 17. The opening of each recess is covered with a flexible diaphragm 15 on the same surface as the surface facing the sole, and an electrical wiring (not shown) is connected to the electrical contact 17 so that a signal generated by the switch ON can be taken out to the outside. Further, the space 20 inside the dome spring 15 serves as a resonance space for impact sound when the dome spring 15 is restored, as will be described later.

  FIG. 3 is a diagram showing a bending state of the two-layer bending acoustic switch unit 2. When the foot pressure increases, the vibration resonance plate 10 bends in a conical shape vertically downward, pushes the center of the dome spring 15 downward, connects the conductive spacer 16 and the electrical contact 17 and turns ON. That is, the flexure diaphragm 10 is deflected in the recess by the load from the sole, and the top of the dome spring 15 (Z region in FIG. 3) disposed in the recess is pushed down by the flexure of the flexure diaphragm 10. Due to the deformation of the dome spring 15, the inner surface of the top of the dome spring 15 comes into contact with the electrical contact 17 disposed inside the dome spring 15 and is switched on.

  When the foot pressure increases, the vibration resonance plate 10 moves up and down in the X region by increasing and decreasing the foot pressure. However, since the bending and restoration are repeated in a conical shape by increasing and decreasing the foot pressure, the vibration resonance plate 10 moves up and down in the peripheral regions Y1 and Y2 of the dome spring. The vertical movement is transmitted only to the Z region at the center (top) of the dome spring.

  In order to flex the diaphragm 10 with the foot pressure in a conical shape, the shape of the recess opening is preferably circular, and the vertical movement is repeated at the center of the vibration resonance space 20 by increasing or decreasing the foot pressure.

  Further, when the flexure diaphragm is released from the load from the sole, the dome spring impacts the flexure diaphragm with the restoring operation of the flexure diaphragm and the dome spring, and generates a vibration sound in the recess. The vibration sound resonates in the resonance space, so that the user can perceive the impact as a timbre and can give a comfortable inner stimulus to the user's sole.

  The conductive spacer 16 and the electrical contact 17 may be made of a conductive material such as metal or carbon, and the conductive spacer 16 may be integrated with the dome spring. The material of the dome spring is preferably a highly conductive metal such as stainless steel.

  FIG. 4 is a reference diagram showing an example of electrical wiring of each channel of the two-layer flexible acoustic switch unit 2 according to the embodiment of the present invention.

  FIG. 5 shows the foot pressure curve P showing the peak of foot pressure increase and decrease according to the embodiment of the present invention and the action of the double-layer flexural acoustic switch 2 that reverses and restores before and after the pressure K that reverses by pushing the center of the dome spring 15. FIG.

  When the foot pressure increases, the flexure diaphragm 10 moves up and down in the X region as shown in FIG. 3 as the foot pressure increases and decreases, but moves up and down in the Y1 and Y2 regions because it repeatedly deflects and restores in a conical shape as the foot pressure increases and decreases. The vertical movement is transmitted to the Z region at the center of the dome spring.

  In the foot pressure curve P that changes according to the movement of the user, the pressure K that reverses by pressing the center (the top of the head) of the dome spring 15 increases with P1 to P2, the electrical signal turns ON, decreases with P3 to P4, and turns OFF. The length of the connection time T is detected.

  By changing the foot pressure reflected on the area into an up and down motion, the flexure diaphragm 10 is repeatedly reversed and restored without distortion, and the electrical connection can be turned on and off at a constant pressure.

The resonance space 20 is preferably a sealed type, and prevents the conductivity from being deteriorated due to adhesion of dust. Also,
If the conductive spacer is made of a material with moderate air permeability such as non-woven fabric, it will not prevent the dome spring from reversing due to decompression.

  The method of pushing and disconnecting at the center of the two-layer flexural acoustic switch unit 2 is not limited to the dome spring.

  FIG. 6A is a cross-sectional view of a main part of a footwear base according to a second embodiment of the present invention. A deflection restoring member 100 is provided on the first layer, and a center pushing projection 101 is attached to the center of the lower surface thereof. In the recessed space 103 below the flexure restoring member 100, the pressure switch 102 that does not generate a vibration sound that can be simply pushed and released to cut off the connection is provided in the second layer, instead of the dome spring, which makes the user difficult to stimulate. The specifications can be used for a long time without any problems.

  FIG. 6b shows the movement of the footwear base according to the second embodiment, wherein the center pushing protrusion 101 is condensed by the body fluid of the skin at the center by the first bending restoring member 100 and bent in a conical shape. The center top of the pressure switch 102 can be pushed in accurately by the vertical movement of X.

  The ON / OFF method of the pressure switch 102 is not limited to the coil type or the contact type. Simply attach an electrical contact at the center of the first layer and connect it with the electrical connection directly provided in the center of the recess space when bent downward. You may block it.

  FIG. 7a is a cross-sectional view of a main part of a footwear base according to a third embodiment of the present invention. Mainly compresses skin cell pressure directly with a fluid with good skin feel, and presses and releases pressure switch 102 to output ON / OFF signal, mainly to achieve both comfort and function. To do.

  It is desirable that the first hard member 114 is hard and bendable, and only the fluid containing portion is compressed. The fluid storage unit 110 is surrounded by a fluid partition wall 111 and stores a fluid such as silicon gel therein. Due to the foot pressure, the fluid in the fluid accommodating portion 110 bites into the recessed space 103, and the center pushing protrusion 112 attached to the lower portion of the fluid accommodating portion 110 contacts the pressure switch 102 and outputs an ON signal.

  The projecting height facing the sole of the fluid storage unit 110 embedded in the first elastic member 115 may be flat or projecting.

FIG. 7b is a sectional side view of the main part during operation according to the third embodiment of the present invention.
By increasing the foot pressure, the second layer of the fluid containing portion 110 is compressed in the range of W1.

  The fluid accommodating part 110 compressed by the area of W1 bites into the hole opening 120 having an area of W2 smaller than the area of W1, and the center pushing protrusion 112 contacts the pressure switch 7.

  The fluid accommodating portion 110 is accommodated by a fluid partition wall 5 such as water, gel, or air that can flow, but may be a recoverable member such as silicon. In addition, the shape of the fluid is preferably circular on the surface that contacts the sole.

  The gap between the pressure switch 102 and the center pushing projection 112 is ensured in a recess space 113 of an arbitrarily determined size, and conduction and non-conduction are caused by the vertical movement of the fluid partition wall 5 having a height H2 larger than the compression sinking height H1 due to an increase in load. A gap for repeating conduction is stably secured.

  FIG. 8 is a footwear pedestal in which the ON / OFF signal coincides with the sense of movement according to the fourth embodiment of the present invention. In order to increase the sensing range (pressure range) at the measurement point of the foot comfort and the output signal, FIG. As a means of sensing pressure (movement of the center of gravity) that can be perceived by the senses, a protrusion that fits the skin cells is provided, and the skin fluid condenses so that the weak pressure of the skin fluid is wrapped around the center of the skin pressure sensing protrusion By doing so, the pressure of the vertical motion at the center of the vertical downward direction is generated, and the ON / OFF signal is output.

  As shown in FIG. 9, the surface layer of the footwear pedestal has an elastic plate 30, a spring insertion space 31, a pressure switch pushing portion 36 made of a hard member, a bottom silicon layer 32, a coil spring 33, a pressure switch 50, a movable groove 40, and skin. The pressure sensing projection 45 is configured.

    In order to turn on / off the pressure switch 50 by increasing or decreasing a weak foot pressure, the shape of the skin pressure sensing projection 45 is spherical, and a pressure is applied to wrap the body fluid of skin cells in the center, and toward the center. It moves up and down vertically and acts on the silicon layer 54 of the pressure switch to push the center of the pressure switch 50.

    As shown in FIG. 8, when the pressure switch is turned ON / OFF by increasing / decreasing the load, when the foot pressure load increases / decreases on the elastic plate 30, P1 and P2 which are different in the supporting force for supporting the sole are provided.

  The supporting force is a mechanism that provides a region where P2 is large and P1 is small, and senses foot pressure in a spot manner in a region where the supporting pressure of P1 is small.

  The mechanism for turning ON / OFF the pressure switch 50 with a weak foot pressure is that when the pressure increases in the P1 region, the skin pressure sensing protrusion is pushed downward, and the coil spring 33 is compressed, so that the pressure switch pushing portion pushes the pressure switch. Connection is conducted.

  When the pressure in the P1 region decreases due to a decrease in foot pressure, the pressure switch is turned off by the restoring force of the coil spring 33.

  The height of the skin pressure sensing protrusion 45 is that the protrusion bites into the dermis cell layer without a sense of incongruity, the biting height is preferably about 0.5 to 0.8 mm, and the shape is circular, and about 10 to 13 mm senses the increase or decrease in skin pressure. Is desirable.

  In the case of this switch system, a subtle change in pressure can be sensed by changing the strength of the spring pressure.

  The pressure switch connection / cutoff method shown in FIG. 8 can determine the threshold (threshold value) by changing the strength of the coil spring 33 or a member having equivalent properties, and according to the purpose of analyzing the motion motion. , Sensing.

  The coil spring large 60 may be a single spring as shown in FIG. 9, and the pressure for restoring the indentation is the sum of the compression resistance of the elastic plate at the P1 region boundary, the strength of the coil spring large 60 and the pressure for connecting the pressure switch 50. It becomes a threshold value for ON / OFF.

  Further, when the foot pressure is sensed by the pressure switches 51 stacked in a multistage manner with different indentation strengths of the pressure switch 50, pressures with different threshold values can be detected at the same measurement point.

  The pressure switches stacked in multiple stages can output the analog amount of foot pressure changing in real time into small, medium, large and 01 signals, and can analyze the operation in three dimensions.

  The method of sensing pressure in a multi-stage manner does not necessarily stack pressure switches in a multi-stage manner, for example, a commercially available multi-stage switch and a load corresponding to the pressure at the fluid bite height shown in the third embodiment. Can be output by sensing ON / OFF.

  By combining the pressure sensor and the ON / OFF sensing switch, a dramatic improvement in exercise performance can be realized.
