Description

Transport aid device for reducing arm joint overload

The present invention relates to a transport aid for reducing arm joint overload, and more particularly, to reduce overload of arm overload due to repetitive tasks such as lifting or unloading an item or moving in a lifted state. A transport aid that also serves as an arm guard.

In general, a worker's transport of goods by human resources takes about 60-80% of the time in the process of producing a product. Especially, the main task of the courier service or quick service workers is transportation. can do.

While lifting, lowering, or transporting items, heavy items are transported using equipment such as hoists or forklifts, but light items are being performed by repetitive work by workers.

This repetitive transport operation not only increases the fatigue of workers, but also may cause safety accidents, and also causes the musculoskeletal disorders, causing frequent industrial accidents.

As an example of the prior art for solving this problem, Korean Patent No. 10-1486588 (Patent Document 1) proposed a stress relief device worn on the shoulder of the user to support the load, the configuration is in use A yoke for transmitting the load to both sides of the shoulder region to avoid stress in the shoulder region, the yoke comprising: a base bridging the shoulder region of the user; A front end comprising a pad extending from the base and proximate the front side of the user's body; And a rear end extending from the base and including a pad adjacent to the rear side of the user's body.

However, in the case of Patent Literature 1, the method of relieving stress through the method of distributing the load of the heavy object to the entire shoulder is useful only in the state of holding the object, and there is no suggestion of reducing the manpower in the process of lifting the object. However, there is a disadvantage in that the utilization is extremely limited.

Republic of Korea Patent Registration No. 10-1486588 (2015.1.26 notification)
