Description

The proposed pedometer is made in the form of a bracelet, worn on the leg a little higher than the ankle joint. Under the influence of the tensions of the tendons that bind the foot to the muscles of the leg, a spring-loaded plate rotates, is located on the back side of the bracelet and controls the movement of the system of counting discs fixed to the outside of the bracelet through the ratchet mechanism.

In the drawing, FIG. 1 shows a side view of the pedometer; FIG. 2 is the same above; FIG. 3 is the same in front; FIG. 4 and 5 is the same position with the corresponding walls removed; FIG. b - vertical section along ab of fig 5; FIG. 7 is the same in cd of FIG. five.

The leg 7 is covered by a bracelet formed by two steel ribbons 6, 7 enclosed by a soft material, connected by a hinge 8 at the front and a lock 9. at the rear. Tape 6 in front of a little goes on the tape 7 and can be advanced along it when adjusting the leg. After adjustment, it is fixed with a simple clip. The swings of the plate 3 under the influence of the tension of the tendons 2 when walking are transmitted by the axis 4 to the tooth 10, which at each

the deviation of the plate 3 turns the ratchet 7 / on one tooth in the direction indicated by the solid arrow in FIG. 6. The spring 5 each time returns the plate 3 to its original position. The second ratchet 12 is fastened to the ratchet 77. The tooth 13, which can be pulled back by the spring J4, prevents the ratchets from rotating backward, which are mounted on the sleeve 75 common to the gear 75, on the axis 4. The small gear 75 transfers the rotation to the large gear 16 mounted on the axis 32. 32, the small gear 17 is fastened, transmitting rotation to the large gear 18 mounted on the axis 33.

On the latter, the small gear 19 is fixed, transmitting the rotation of the large gear 20 mounted on the hub on the axis 32. On the same sleeve there is a small gear 21 transmitting the rotation of the large gear 22 mounted on the hub on axis 33.

The counting disc system, which is counted, is mounted on the outside of the bracelet and is associated with the corresponding gears. The disk 23 is mounted on the 16 axis 32 common with the gear 16. The numbers 0, 5, 10, etc., are marked on it up to 100. These figures are visible on the device in the window 24; An approximate count of 25 steps is indicated. The counting disk 25 is mounted on a common axis 19 with the gear 19. The numbers from O to 9 inclusive are marked on it.

denoting hundreds of steps. They are visible through the window 26 (an approximate count of 3 hundreds). The disk 27 is mounted on a common sleeve with serrations 20-21; it contains numbers from O to 9, denoting thousands of steps (approximate count of 7 thousand hours). The numbers are visible through the window 28. The disk 29 is mounted on a common hub with the gear 22; it contains numbers from 0 to 9 ten thousand steps (approximately 50 thousand hours). The numbers are visible through the window 30.

FIG. 1 shows an approximate count of 57325 steps.

Windows 24, 26, 28, 30 are covered with glass or another transparent plate to protect the counting device from water and dust.

The point of entry into this device of axis 4 is hermetically sealed with a rubber ring 5 / (Fig. 7).

The subject matter of the invention.

A pedometer in the form of a bracelet covering the leg above the ankle joint, characterized by the use of a spring-loaded plate 3, reinforced from the back side of the bracelet, swinging on the axis 4 under the influence of the tension of the tendons during walking and controlling by means of the ratchet mechanism 10, 11, 12, 13 movement of the counting discs 25, 25, 27, 29, reinforced on the outside of the bracelet.
