JPH01265382A - Counter terminal for jumping rope - Google Patents

Abstract

PURPOSE:To simplify the structure of a counter terminal for a jumping rope without using expensive parts such as a magnetic reed switch by counting the number of the times of the turning of the jumping rope by turning on/off the rotations of a rotary member and a detecting member by a signal generated from a circuit part according to whether a conductive plate and a spring member are contacted or non-contacted. CONSTITUTION:When a rope jumping is started, a rotary member 2 rotates according to the turning of a rope 1, and a detecting member 3 also rotates. The signal generated from a counting function part 10 is detected by conducting when a spring member 11 and a conductive plate 4 are contacted with pressure, and a counting is executed. A count displayed on a liquid crystal display device 7 is increased for one by this counting, and the display device 7 executes a display with a voice by a piezoelectric element 6. When the spring member 11 cuts off the contact with the conductive plate 4 by the turning of the rope 1, the signal generated from the counting function part 10 is stopped, and the counting function part 10 executes the counting according to the existence of the conduction of the spring member. Thus, the structure of the counter terminal can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a skipping rope counter device that counts the number of jumps made with a skipping rope.

[Conventional technology]

The conventional counter device for rope skipping has rope 10 as shown in Fig. 2.
The rotation is transmitted to the fixed member 2, and the drum display body 22 is rotated by the rotation of the gear of the gear 21 to display the number of times.

Therefore, the shape of the grip portion 25 is limited by the diameter of the drum display 22, and since the rotation of the gear 21 and the display on the drum display 22 are mechanically matched, the grip portion 25
If you hold 3 in the opposite direction to the setting side or jump rope in the opposite direction,
When I measured backwards, the displayed value had decreased.

[Problem to be solved by the invention]

SUMMARY OF THE INVENTION The present invention is intended to solve these problems.The purpose of the present invention is to combine the rotating structure into a funbakuto, provide a rotating display section without being mechanically restricted, and provide an easy-to-use system for users of jump ropes. To provide a jump rope counter device that measures jump rope without imposing any restrictions.

[Means to solve the problem]

The skipping rope counter device of the present invention includes: α) A rotating member that fixes a skipping rope and rotates together with the rope.

b) a detection member provided with a conduction plate that engages and rotates with the rotating member; C) a spring member that presses against the conduction plate and turns on and off an electric signal by contact with the same; d) a detection member that transmits an electric signal to the spring member. ε) A liquid crystal display for displaying the count based on the output of the circuit.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded view of an embodiment of a skipping rope counter device according to the present invention, and FIGS. 3 and 4 are cross-sectional views showing the detection member in this embodiment when it is conducting and when it is not conducting.

In FIG. 1, a rope 1 is fixed to a rotating member 2. In FIG. A conductive plate 4 is fixed to the detection member 5 by a ring 14, and is engaged with the rotating member 2 with three projections and depressions.

A piezoelectric element 12 for audio notification is fixed to the upper case 5, and a liquid crystal display 7 and a connector 8 for signal transmission are fixed to the lower case 6 by a circuit board 9 having a counting function.

Two spring members 11 are fixed on the circuit board 9 by screws 13, and are pressed against the conduction plate 4 and energize the count function section 10.

The piezoelectric element 12 is also electrically connected to the circuit board 9. When jumping rope starts, the rotating member 2 rotates together with the rotation of the rope 1. The detection member 3 also rotates.

The signal emitted from the counting function section 10 is detected by conduction when the spring member 11 and the conduction plate 4 are in pressure contact with each other as shown in FIG. 3, and is counted.

As a result of this counting, the count displayed on the liquid crystal display 7 is incremented by 1, and the piezoelectric element 6 provides an audio display.

As shown in FIG. 4, when the spring member 11 comes into contact with the conductive plate 4 due to the rotation of the rope 1, the signal emitted from the count function section 10 is interrupted. As described above, the counting function section 10 performs counting depending on the presence or absence of conduction of the spring member.

It is desirable that the conductive plate 4 is coaxially wrapped around the detection member 3 by about 180°. Further, if a groove is provided at the place where the conductive plate 4 comes into pressure contact with the spring member 11, the contact will be more reliable.

In this embodiment, the rotating member 2 and the detection member 3 are constructed as separate parts, but they may be constructed as a single part.

Further, as in this embodiment, if the count is displayed on the liquid crystal display 7 and also audibly displayed by the piezoelectric element 12, the counting function can be confirmed, which is very useful.

[Efficacy of the invention]

As described above, the present invention relates to a rotating member and a detection member.

The number of rotations of the rope can be counted by the signal emitted from the circuit being turned on and off by contact and non-contact between the conductive plate and the spring member, and expensive parts such as magnetic reed switches can be counted. It is possible to provide a jump rope counter device with a simple configuration and high practical value without using any.

By using a liquid crystal display, there are no restrictions on where the display can be installed compared to conventional drum displays.

Also, since the count is based on the on/off signals emitted from the circuit, there is no need to count backwards even if you specify which side to hold the grip on or jump rope in the opposite direction.
