Mechanism and structure of the counting machine

Abstract

To provide a mechanical counting machine that can be easily operated without hindering a movement, has excellent visibility, and is water-resistant when counting numbers while performing a specific exercise or action such as swimming. [Solution] The tallying machine is made up of exterior rings 2 and 3 that encase the numbers 0 to 9 evenly on the outer surface of a cylindrical number ring 1, which are inserted into the fingers and contain the ring, and a lever 4 that rotates and advances the numbers one by one. In addition, when rotating and advancing the number ring 1 one by one with the operating lever 4, a click feeling is felt to ensure a reliable lever stroke, and in order to ensure that the number ring is held in place with a certain resistance after being rotated, the feeding receiver, band-shaped protrusion, detent, and pusher are appropriately designed and configured without using metal springs or the like.

Description

[Technical Field]

[0001] This invention relates to the mechanism and structure of a small counting machine that can be worn on the fingers and allows you to count numbers less than 10 without interfering with specific activities. [Background technology]

[0002] There are cases where you want to count numbers such as laps or frequency while exercising, mainly swimming or running, or while engaging in some other activity.

[0003] In such situations, various types of counting machines are sometimes used to prevent counting errors caused by relying solely on memory.

[0004] Furthermore, the counting machine is required to be portable, easy to operate, and visible so as not to interfere with the exercise or activity being performed using it.

[0005] Although counters with various structures and mechanisms, such as mechanical and electrical types, have been commercially available or have been devised, there has not been a mechanical counter that is easy to operate without interfering with swimming movements, has excellent visibility, and is resistant to water intrusion.

[0006] [Patent Document 1] Actual Publication No. 07-001969 [Patent Document 2] Jitsuzen Showa 51-001061 Summary of the Invention [Problem to be solved by the invention]

[0007] To provide a mechanical counting machine that can be easily operated without hindering a movement, has excellent visibility, and is water-resistant when counting numbers while performing a specific exercise or action such as swimming. [Means for solving the problem]

[0008] The tallying machine is made up of a cylindrical number ring (1) with numbers from 0 to 9 evenly arranged on the outer surface, exterior rings (2) and (3) that enclose the ring and are inserted into the fingers, and a lever (4) that turns the numbers one by one.

[0009] When the number ring (1) is turned one character at a time with the operating lever (4), a clicking sensation is felt to ensure a reliable lever stroke, and after the turning, the number ring (1) is held in place with a certain resistance. In order to achieve this, the number ring (1) is configured to have a receiving part (5), a strip-shaped projection (7), a stopper (8), and a pusher (10) that are appropriately designed and shaped, without using metal springs or the like. [Effects of the Invention]

[0010] By wearing the counting machine of this invention on the fingers, it can be counted by simply operating the lever without interfering with activities such as swimming, and has the advantage that each number is relatively large and therefore highly visible.

[0011] By using a mechanical resin system that does not use metal springs, etc., there are advantages to not losing functionality due to water intrusion and the system can be manufactured inexpensively. [Brief explanation of the drawings]

[0013] To implement this invention, the number ring (1) is provided with a receiving portion (5) for each number, as shown in Figure 2, and two rows of band-shaped protrusions (6) on the inner surface to facilitate smooth movement of the ring. In addition, the exterior ring (2) and (3) are divided into two parts for ease of assembly and are provided with a number viewing window (7), a rotation stopper (8), and an operating lever receiving groove (9). The operating lever (4) is provided with a pusher (10) having a curvature that fits along the number surface of the number ring (1). [Example]

[0014] As shown in Figure 4, the device is attached to the fingers by holding it near the second joint of the index finger, and in this state, the user is engaged in an activity such as swimming. At this time, the operating lever should be in the (11) position in Figure 2, and when counting, use your thumb to move the lever to the (12) position until you feel a click, then return it to the original (11) position until you feel a click, and the number in the viewing window (7) will advance by one. By properly arranging the shape, thickness and length of the detent (8) and the plunger (10), the number ring can be held in place and a clicking sensation can be achieved. [Explanation of symbols]

Claims

1. The mechanism and structure of a mechanical counting machine consists of a cylindrical number ring (1) with numbers from 0 to 9 evenly distributed on the outer surface, outer rings (2) and (3) that encase it and are inserted into the fingers, and a lever (4) that turns and advances the numbers one by one.

2. The mechanism and structure of the mechanical numbering machine is such that when the number ring (1) is turned one character at a time with the operating lever (4), a click feeling is felt to ensure a reliable lever stroke, and the number ring is held in place with a certain resistance after being turned. This mechanism and structure of the mechanical numbering machine is such that the receiving part (5), the strip-shaped protrusion (7), the stopper (8), and the pusher (10) are provided in an appropriately designed shape, without using metal springs or the like.
