Measuring device

Abstract

A measuring device is provided for a training device that includes a weight, a wire that is connected to a first end of the weight, and a load generating unit configured to move the weight upward by moving a second end of the wire. The measuring device comprises a position detecting unit configured to detect the position of the weight, a load detecting unit configured to detect the load that is applied to the wire, and a display unit configured to display report data based on the detected data obtained by the position detecting unit and the load detecting unit. Each of the position detecting unit, the load detecting unit, and the display unit comprises an attachment portion, which is attachable to and detachable from the training device.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of PCT Patent Application No. PCT / JP2005 / 000361 filed on Jan. 14, 2005, which claims priority to Japan Patent Application No. 2004-008947 filed on Jan. 16, 2004. The entire disclosures of PCT Patent Application No. PCT / JP2005 / 000361 and Japan Patent Application No. 2004-008947 are hereby incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a measuring device for a training device. [0004] 2. Background Information [0005] Some training devices comprise a measuring device for measuring the exercise state of a trainee. For example, a conventional training device is known which comprises a measuring unit for counting the number of weights a trainee lifts and the number of times that he / she lifts them. The number of weights and the number of times the weights are lifted are counted with the measuring unit that is arranged in the...

AI Technical Summary

Benefits of technology

[0020] As described above, the measuring device according to the present invention can calculate the mass of the stopped weight and display the above-mentioned data on the display unit as well as detect the load which is applied to the elongated member. When the weight is moving, the load being lifted by the trainee is displayed. For example, the more the weight is moved vigorously, the larger the displayed value of the load will become. Consequently, this gives a trainee incentive to work out. In addition, when the weight is stopped, the mass of the weight is displayed. Therefore, the measuring device provides excellent operability in that a trainee does not have to look at the weight itself as he / she does with a conventional weight training machine, and a trainee can easily check the mass of the weight which is being used at present, the number of times he / she performed a movement in a work out, and the like by just looking at the display while maintaining his / her training position.

[0029] A training load for a training device such as a weight training machine is changed by changing the number of weights which have the same weight. Therefore, it is possible to apply the measuring device to this type of training device by including data on the mass of a single weight, and data on a mass which is calculated by multiplying the mass of the single weight by an integer corresponding to the number of the weights. Furthermore, the mass of a single weight may be changed depending on the training device, and the data includes the mass of a plurality of single weights which are prospectively assumed to be used, and the mass calculated by multiplying the mass of one weight by an integer. As mentioned above, the storage capacity of the mass storing unit can be kept low with no waste by limiting the mass data to the necessary and minimum data.

[0030] A measuring device according to the present invention provides a cost advantage to a fitness center and the like, because the device can be easily attached afterwards to an existing training device that does not have a measuring portion for measuring the number of times that a trainee has performed a movement in a work out and the like. In addition, because the mass of the weight is calculated based on the load applied to the wire or the like which pulls the weight, a trainee does not have to look at the weight itself in order to check the mass of the weight. A trainee can check the number of the times he / she has performed a movement in a work out and the like as well as the mass of the weight by just looking at the display. Therefore, the measuring device provides excellent operability for a trainee, because he / she does not have to move unnecessarily.

Problems solved by technology

Consequently, many more detecting units and detected units will be required to apply the above-described measuring unit to a variety of training devices, which makes their structures more complicated.

Therefore, if a fitness center and the like would like to introduce a training device that has a measuring unit, they will have to purchase a new training device, which will impose a heavy cost burden on them.
