Description

Finger strength measuring device {Finger strength measuring device}

The present invention relates to a device for measuring finger muscle strength, and more particularly, to a device for testing that can be used to confirm or predict a climbing grade and ability evaluation, and training performance in the field of climbing.

Sports climbing (sports climbing, 人工岩壁登攀) is a leisure sport that climbs toward a target point using hands and feet along a hold installed on an artificial rock wall structure, and is also called 'artificial rock climbing'. Since it began in the 1940s as an educational training for professional mountaineers in France, it was adopted as an official event of the 32nd Olympic Games (Tokyo Olympics).

The only way to evaluate climbers' grades and individual abilities is to obtain a course grade by climbing the actual climbing course, and the course grade is converted and applied with a 'grade conversion table'.

In order for club members and other athletes to check the performance of climbing training, they have to climb the actual climbing course, but there are many difficulties such as the time to travel to the nationally scattered climbing courses, the time to prepare climbing equipment, and the cost involved.

In order to solve these difficulties, it is necessary to develop a finger strength device that can easily identify individual training performance and ability in the field.

The currently developed finger muscle strength measurement device has a problem in that the specificity of climbing is not considered.

The third driving unit may include a driving device.

5 to 8, the second hold 920 is a component for pulling the second load cell 900 with a thumb.

Since the second hold 920 is coupled to the second load cell 900, pulling the second hold 920 can pull the second load cell 900.

Since the second hold 920 is coupled to the second load cell 900, when the second load cell 900 is moved, the second hold 920 can also be moved.

Since the second hold 920 can be moved, the position of the grip holding the second hold 920 can be adjusted as needed.

The second hold 920 may be formed of a metal plate or a wooden plate.

The second hold 920 can be detached from the second load cell 900 .
