Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a pedometer, and more particularly to a pedometer having features in its mounting structure.

(Background Art) Conventionally, as shown in Utility Model Application No. 56-153812, for example, a pedometer main body having a display section is fixed to a shoe with a string, and a sensor such as a piezoelectric element is arranged inside the shoe. A pedometer that is electrically connected to the pedometer body has been proposed.

However, according to this, in order to remove the pedometer body when replacing the pedometer when it is damaged and replacing it, or when cleaning the pedometer, it is necessary to disconnect the piezoelectric element and untie the string. It was extremely troublesome because it required complicated labor.

(Object of the invention) The present invention has been proposed in view of the above-mentioned drawbacks.
The purpose of this is to make it possible to easily attach and detach only the pedometer body with the display part from the shoe, and to create a structure that allows reliable electrical connection between the sensor and the pedometer body at the same time as installation. To provide a pedometer which is convenient during inspection and cleaning of shoes and whose main body can be held securely.

FIG. 1 shows an embodiment of the present invention, and the present invention comprises a sensor 1, a mounting base 4 to which a lead wire 3 as a lead wire drawn out from the sensor 1 is directly connected, and a mounting base 4 that is connected to the mounting base 4. It consists of a pedometer body 2, and a sensor 1 is built into the Irusole Sa, which is installed inside the Shoes S.
The main body 2 is attached to shoelaces Sb of Shoes S through the mounting base 4.
It is said that it can be attached and detached from the part (see Fig. 5).

Here, the sensor 1 is composed of a pair of contact electrodes 5 in the form of thin flakes having elasticity such as phosphor bronze.
One of the electrodes is flat and the other is curved.Although they are always separated, when a load is applied, the curved contact electrode 5 bends and makes contact with the other contact electrode 5, which changes the load due to weight shift. It is arranged on the lower surface of the part of the insole Sa that corresponds to the area from the ball of the foot to the base of the index finger so that it can be easily detected. Note that 6 is a protective cover that covers the sensor 1 to make it waterproof.
Further, the lead wires 3 led out from each contact electrode 5 of the sensor 1 are wired along the inner surface of the shoe S and drawn out to the outside of the shoe S.

Next, the mounting base 4 includes a substantially box-shaped accommodating part 7, a frame-shaped cover 8 connected to one end of the accommodating part 7 and having an opening 8a, and a frame-shaped cover 8 connected to the other end of the accommodating part 7. The main element is the provided lid stopper piece 9. A pair of terminal electrodes 7b connected to the conductor of the lead wire 3 inside the housing part 7 are exposed at one edge of the inner surface of the housing space 7a recessed in the housing part 7. Attachment frames 10 for attaching the mount 4 to the shoe S are attached to both sides, respectively. Further, recesses 7c are formed on the top surface of both ends of the housing portion 7, and are adapted to engage with engagement protrusions 14a of the main body 2, as will be described later.

Here, the mounting base 4 is made of a material with high bending rigidity, such as polypropylene, and has a housing portion 7.
The cover 8 and the lid stopper piece 9 are connected by thin hinge parts 11, respectively, so that the cover 8 and the lid stopper piece 9 can be opened and closed easily.

An engaging portion 9a is provided on the lower edge of the lid stopper piece 9, and when the cover 8 is overlapped near the free end of the cover 8 by rotation, this engaging portion 9a fits into the engaging groove 8b on the surface of the cover 8. It's starting to engage.

Next, Figure 2 shows the pedometer main body, which has a built-in button-type battery 12 as a power source and a liquid crystal 13 as a low power consumption display section, and is made of molded material such as ABS resin. A housing 14 and a bottom plate 15 formed as a single product and equipped with engaging protrusions 14a on both sides, a transparent display surface cover 16,
Liquid crystal fixing plate 17 for positioning the liquid crystal 13, liquid crystal 1
3, a viewing plate 18, a printed circuit board 19 on which a one-chip microcomputer is mounted, a printed circuit board module fixing plate (electrode plate) 20, which holds the battery 12 and connects the battery 12 and the printed circuit board 19. It consists of a battery holder 21 for fixing the battery 12, a waterproof rubber sheet 22, etc., a pair of terminal electrodes 23 are provided on the bottom plate 15, and a side surface of the housing 14 is used for inputting constants such as stride length and preset values. constant setting button 24, time unit feed button 25 for setting the time unit of the preset value, and clear button 26 for resetting the display.
However, on the top surface there are a mode switching button 27 for switching between step count display mode and stopwatch mode, a step count/distance switch button 28 and a stopwatch button for switching the display to step count and distance, which is the value obtained by multiplying the step count by the stride length. A start/stop button 29 is provided. In the figure, 30 is a conductive rubber that makes an electrical connection between the liquid crystal and the printed circuit board 19, and 31 is a tammy rubber that holds the end surface of the liquid crystal on the opposite side of the conductive rubber 30.
Reference numeral 32 denotes an O-ring for waterproofing each button part, which is made waterproof by the waterproof rubber sheet 22 and O-ring 32 for waterproofing the joint surface between the housing 14 and the bottom plate 15 and the terminal electrode 23 part. . Note that 33 in the figure indicates a nameplate.

The main body 2 is accommodated in the housing portion 7a while the engaging protrusion 14a of the housing 14 is engaged with the recess 7c of the mounting base 4 shown in FIG. Thereby, the terminal electrode 23 of the main body 2 and the exposed terminal electrode 7b of the mounting base 4 come into contact with each other, and the main body 2 and the sensor 1 are connected. FIG. 3 shows the connection state of both terminal electrodes 23 and 7b.

FIG. 4 shows a state in which the main body 2 is housed in the mounting base 4, the cover 8 is closed, and the lid stopper piece 9 is overlapped and fixed on the free end side, and A in FIG.
- Corresponds to A enlarged sectional view.

That is, since the engaging portion 9a of the lid piece 9 reliably engages with the undercut-shaped engaging groove 8b of the cover 8, the main body 2 is pressed against the housing portion 7 with appropriate pressure, and the terminal electrodes 23, 7b are to be reliably connected by appropriate contact pressure. Also,
When removing only the main body 2 when cleaning the Shuse S, open the lid stopper 9 and the cover 8 and remove the main body 2.
All you have to do is take it out.

As shown in FIG. 5, the insole Sa on which the sensor 1 is installed is placed inside the shoe shoe S, and the main body 2 is attached to the mounting base 4, which is attached by passing the shoelace Sb portion of the shoe shoe S through the mounting frame 10. If you walk or run while wearing it, sensor 1 will be activated every time the Shuse S receives the weight of the human body when it lands on the ground.
This conduction is counted by a microcomputer in the main body 2. When this count value is displayed, the number of steps is shown, and when the value obtained by multiplying the number of steps by the stride length is displayed, the distance is shown. Of course, this pedometer is attached to one of the Shoes S,
Since the number of steps indicates the number of times one foot touches the ground, the actual number of steps is twice the value. Also, the stride length is input in addition to the length of two steps. Of course, there is no problem if the actual number of steps is displayed through electrical processing, or the value of one step is input as the length of the step. These displays are switched through the opening 8a of the cover 8 by operating various buttons.

In addition, in this example, sensor 1 is used as an insole.
Although the case where the sensor is provided inside the S is shown, it is of course possible to adopt a configuration in which the sensor is detected outside the S using a contact spring or a piezoelectric element. Further, although the mounting base 4 is detachably attached to the Sb portion of the shoelace, the mounting position is not limited and may be selected as appropriate.

(Effects of the Invention) As described above, according to the present invention, a sensor for detecting the number of steps is attached to the shoe, and a terminal electrode connected to the sensor is exposed on the mounting base, and the sensor is attached to the shoe. a removable pedometer main body, which is provided with a display section for displaying the number of steps, etc. on the top surface, and a terminal electrode that is connected to the terminal electrode by being pressed into contact with the terminal electrode when accommodated in the accommodating section of the mount; The main body can be attached and detached easily and quickly, and the main body and sensor can be electrically connected or separated at the same time as this attachment/detachment operation, making it extremely convenient for frequent attachment and detachment without the need for complicated labor. It has the effect of being.

Further, when the main body is housed, the main body can be held securely and has the advantage of being resistant to vibrations and shocks.
