Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is used for a box for storing electrical equipment such as a switchboard and a control panel, in which a handle is triggered by releasing elastic force of a spring by releasing a hook. The present invention relates to an improvement of the flat handle device.

(Prior Art) In the conventional flat handle device of this type, the handle is pushed into the main body storage portion against the elastic force of the spring, and the locking portion at the end of the handle is locked to the hook provided on the main body. Usually, the handle is stored in the main body storage portion and the hook is released by operating the push button facing the front surface of the main body (for example, Japanese Utility Model Laid-Open No. 59-168465).

(Problems to be solved by the invention) However, in such a conventional flat handle device, since the push-button for releasing the hook is located on the outer side in the longitudinal direction of the handle, the handle can be installed by the amount corresponding to the installation of the push button. Not only does it need to be short, but the front of the handle is non-resistive when the push button is pressed, so the handle is triggered by the spring force at the same time as the push button is operated, giving the operator some fear. There is also the inconvenience.

(Means for Solving the Problem) The present invention has been made to solve the above-mentioned problems, and is always caused by the elastic force of the spring in the recess for storing the handle provided on the front surface of the main body. The biased handle is housed so that it can be lifted up and down, and the shaft in the recess of the main body is provided with a hook that is stretched on the back of the handle, a hook portion that engages and disengages, and an inclined pressed surface that is located on the side thereof. The slide lever is slidably supported, and the back surface of the handle is provided with an inclined pressing surface which comes into contact with the pressed surface when the handle is further pressed.

(Example) Next, the Example of this invention is described in detail based on drawing.

(1) is a main body having a recess (2) for storing a handle on the front surface,
Reference numeral (3) is a handle that is housed in the recess (2) so that it can be raised and lowered. The base of the handle (3) is pivotally supported by the shaft (5) in the recess (2), and is constantly urged in the direction in which the handle (3) is constantly urged by the elastic force of the spring (4). Further, a hook (6) having the outer surface of the tip as a guide surface is provided on the back surface of the handle (3) so as to slidably support the hook (6) on the shaft (7) of the recess (2). By engaging the hook portion (9) above the slide lever (8), the handle (3) is housed in the recess (2) against the elastic force of the spring (4).

A compression coil spring (10) surrounding a shaft (7) is interposed between one side surface of the slide lever (8) and the inner wall surface of the recess (2), and the slide lever (8) is hooked (6). ) Side is urged to rotate. Further, a cutout (11) is formed below the other side of the slide lever (8),
By locking the notch (11) with the stopper piece (12) protruding from the other inner wall surface of the recess (2), the handle (3) slides even when the handle (3) is raised from the inside of the recess (2). The lever (8) is erected as shown in FIG.

Reference numeral (13) is an inclined pressing surface provided on the inner surface of the handle (3). Reference numeral (14) is an inclined pressed surface formed at the upper corner of the slide lever (8). Then, by further pressing the inclined pressing surface (13) of the handle (3) toward the pressed surface (14) of the slide lever (8) from the state shown in FIG. 8, the elastic force of the coil spring (10) is increased. Against slide lever (8)
Moves on the shaft (7), hook (6) and hook part (9)
Can be released.

Reference numeral (15) is a step portion continued below the hook portion (9) of the slide lever (8). When the slide lever (8) moves to disengage the hook (6) from the hook portion (9) and the handle (3) is raised, the step portion (15) has its side surface on the side surface of the hook (6). The slide lever (8) immediately returns to the hook (6) and the hook portion (9).
To prevent the re-engagement.

Reference numeral (16) is a key provided on the lower portion of the main body (1) as required, and the locking piece (17) is fitted into a groove hole (18) recessed at the lower end of the handle (3) to handle ( The purpose is to prevent the accidental occurrence of 3).

In this embodiment, the locking plate (not shown) is rotated to release the locking of the door at the same time when the handle (3) is triggered, and the locking plate is provided at the rear end of the proximal end of the handle (3). A rotating arm (19) is provided in series and extends from a long hole (21) formed through the back plate (20) of the main body (1).

(Operation) The one configured in this manner is always shown in FIGS.
As shown in the figure, the handle (3) has a hook (6) stretched on the back surface thereof, and a hook (9) of a slide lever (8) is locked to the recess (2) of the main body (1) for storing the handle. ) Is stored inside. As described above, the handle (3) housed in the recess (2) is attached to the hook (6) and the hook portion (9).
In order to release the engagement and cause it, the tip of the handle (3) is pressed to the inside of the recess (2) with fingers as shown in FIGS. 3, 4, and 5. As a result, the inclined pressing surface (13) of the handle (3) presses the pressed surface (14) of the slide lever (8) to move the slide lever (8) laterally, and the hook of the hook portion (9). Since the engagement with (6) will be released, if the pressure on the handle (3) is loosened,
As shown, the handle (3) will be triggered by the resilient force of the spring (4). When the notch (11) of the slide lever (8) separates from the stopper piece (12), the force of the compression coil spring (10) tends to tilt the slide lever (8), but the tip of the hook (9). Is locked to the inner surface of the handle (3), the slide lever (8) does not fall greatly.

When the handle (3) is thus raised, the slide lever (8) returns to the position where it is again engaged with the stopper piece (12) by the action of the compression coil spring (10).
Therefore, when it is desired to store the handle (3) in the recess (2) again, if the tip of the handle (3) is pressed, the hook (6) stretched on the back surface of the handle (3) is guided by the inclined guide surface. While being guided, it engages with the hook portion (9) of the slide lever (8) and is housed inside the recess (2) against the elastic force of the spring (4).

(Effect of the Invention) As is apparent from the above description, the present invention is provided with a slide lever for accommodating the handle in the recess of the main body against the elastic force of the spring, and the hook of the handle and the slide lever are Since the engagement with the hook portion is released by pressing the handle from the surface side into the concave portion, it is not necessary to provide the push button for releasing the hook outside the concave portion for accommodating the hand.

Therefore, according to the present invention, the handle can be lengthened without increasing the overall size and the handle operation can be facilitated, and since the surface of the handle is in contact with fingers when the handle is pulled, the handle can be easily handled. It will not be scared by being triggered all at once.

Therefore, the present invention is of great practical value as a flat handle device that solves the conventional problems.
