In this rotary handle device, it is premised that the support frame is attached to the opened / closed body such that the side portion comes to a lower position of the handle main body, and the bias load of the arc-shaped handle portion is defined as a rotational moment. Since the locking projection is pressed against the back side of the side portion, the handle body is held in a state in which the handle body is entirely housed in the receiving opening.
[0004]
On the other hand, when the support frame is mounted on the opened / closed body such that the side portion comes to the upper position of the handle main body, there is no means for resisting the rotational moment due to the bias load, so that the handle main body has its own weight. In some cases, the arc-shaped handle portion may protrude toward the front side of the support frame body and cause obstacles such as traffic. For this reason, the arrangement of the conventional rotary handle device is limited to one.
[0005]
In order to avoid the limitation of the arrangement form, a spring-biased push button is provided on the support frame body in opposition to the end outer surface of the front plate portion opposite to the end portion provided with the locking projection. When the front panel is housed flush with the support frame, the front end of the push button abuts on the outer surface of the end of the front panel. , Patent Document 2).
[0006]
However, in this rotary handle device, the handle body is constantly urged to rotate in the projecting direction by a spring, and the push button is mounted on the support frame by a transverse pivot parallel to the front surface of the member to be opened and closed. Therefore, when a part of the body of a passerby or another object being transported accidentally presses the push button, the handle main body may unintentionally protrude.

When the handle body is housed in one, the locking projection abuts against the back side of the side portion, and the locking arm portion of the locking plate is elastically engaged with the locking projection. Is held in the storage position.
[0011]
Since this holding is temporary locking using elastic force, when it is desired to perform full-scale locking more strongly, a rotation operating tool is inserted into the rotation operating portion of the lock shaft, and the lock shaft is attached to the support frame. The locking plate is rotated in a predetermined direction, and the tip of the locking plate is engaged with the back side of the locking projection. As a result, the movement of the locking projection is prevented, so that the handle main body is accurately restrained and held by the storage position.
[0012]
When the handle body is used for the opening operation of the opened / closed body, if the locking by the locking plate is performed, first, the lock shaft is turned in the opposite direction to the direction by the rotary operating tool. And the locking plate is retracted out of the rotation locus of the locking projection. After that, the elastic engagement between the locking projection and the locking arm is released by pressing the front surface of the end of the front plate on the side where the locking projection is provided with a finger.
[0013]
After the elastic engagement is released, when the front face of the end portion is slightly pressed, the handle body turns around the transverse pivot in the protruding direction, and the arc-shaped handle portion protrudes from the receiving opening. By putting a finger on the arc-shaped handle and pulling it forward, the opened / closed body is opened around a hinge shaft (not shown).
[0014]
After closing the body to be opened and closed, the handle body is pushed into the receiving opening about the transverse pivot and rotated, so that the locking projection and the locking arm section elastically engage at the end of this rotation. Thereafter, full-scale locking by the locking plate is performed as necessary.
