However, in the case of the carrying handle 1 having the above-mentioned conventional structure, the following problems occur. That is, the position where the carrying handle 1 is set and fixed is closer to the bottom plate portion 3 side (left end portion in the figure) than the central portion of the word processor 2 on the main body side as shown in FIG. Therefore, the arm 4 of the carrying handle 1 is not set on the extension line of the center of gravity (point P in the figure) of the main body of the word processor 2.

Therefore, when the carrying handle 1 is used to lift and move the word processor 2 in the direction of arrow a at this set position, the set position of the carrying handle 1 is not on the extension line of the center of gravity, so that the word processor 2 It tilts in the direction of the arrow b, and a load is applied to the supporting portion of the carrying handle 1 and the word processor 2.

As a result, the sense of stability is lost and it becomes difficult to hold, and the protrusion 6 and the engaging portion 8 which are engaged with each other due to the extra load due to the inclination are worn out to shorten the life. There was a problem.

In view of the above, the present invention has solved the above-mentioned problems, and the carrying handle can be easily moved to the extension line of the position of the center of gravity at the time of setting and a stable feeling for eliminating an extra load applied to the supporting portion. This is a proposal for a carrying handle mechanism with certainty.

[0012]

In order to solve the above-mentioned problems, in the present invention, a carrying handle which can be stored in an article is attached so as to be rotatable by a predetermined angle and movable by a predetermined length, and a rotating shaft is attached to the carrying handle. An engaging groove in which the rotating shaft and the engaging means are slidable is formed in a storage groove provided in the article, the engaging portion provided in the engaging groove, and the engaging means. Is provided with a fixing means that can be locked.

When the carrying handle is rotated by a predetermined angle with respect to the article, the carrying handle moves on an extension line of the position of the center of gravity of the article.
