2. Description of the Related Art Conventionally, as the above-mentioned flat handle, the ones shown in FIGS. 6 and 7 are known. In the one shown in FIG. 6, the upper end side of the handle b is located at the opening of the case a. It is pivotally attached by a shaft pin c.

Next, referring to FIG. 7, the handle b is in a usable state by pivotally attaching the upper end of the handle b with a shaft pin c in the case a with a spring d interposed therebetween. It is pivotally attached by urging the turning power, and at the lower part of the case a, a latch e is freely retractable inside the case a and a spring f
The handle b is attached so as to project into the case a via a spring.
The handle b can be held in the housed state by being latched, and the handle b can be projected to the position indicated by the two-dot chain line by the pulling operation of the latch e.

In this type of handle, however, the handle b is stored flush with the case a. Therefore, in the former case, the state shown by the solid line in the figure is changed to the two-dot broken line in the figure. In order to incline it to the used state, the upper part g of the handle b is pushed in. However, not only the location for pushing in must be selected and pushed in correctly, but also a considerable pushing force is required. In addition, since it is difficult to determine the pivotally connected portion by the shaft c from the outside in the stored state, it is difficult to know where to push in, the operation position, and the handle operability is poor. is there. On the other hand, the latter is not preferable in that the window h for sliding the latch e and the latch e are exposed to the outside, so that a simple design feeling cannot be obtained, and further, the size required for mounting the latch e is small. There is a drawback that it becomes larger and larger than the former.

Therefore, in order to eliminate the above-mentioned defects, a handle which is already biased by the handle spring and is locked at a position protruding from the front surface of the door is provided, and the handle resists the handle spring. When the handle is pushed in, a locking device for locking the handle in a state where the front end face of the handle is flush with the front surface of the door is further provided. Japanese Patent Application Laid-Open No. 56-37773 discloses a structure in which a locking device is released and a handle is returned to an original position protruding from a front side of a door by a handle spring.

[0006]

However, in the case of the above proposal, not only is the handle spring provided directly below the handle and on the same axis, but the lock is provided below the handle as well. Since a device is provided and the handle and the handle have to be associated with each other, the distance from the handle to the locking device becomes large, resulting in a handle device with a very long depth, which can be called a flat handle. There is a difficulty that you can not get things.

As a result of studies in view of the above-mentioned problems of the conventional example, the present invention provides a novel flat handle, which is projected from the bottom of the case or the rear surface of the handle in order to allow the handle to be retracted. By fitting the guide rods or guide cylinders to each other and fitting the springs to them, not only the overall thickness can be reduced, but also the handle is stopped at the protruding position. The purpose of the product is to make it possible to make the stopper mechanism thin so that the depth of the flat handle can be made thinner and its width can be made smaller, thus enabling the product to be made smaller. Is.
