Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a flat handle that is attached to the door of an outdoor electrical equipment storage box or the like.

(Prior art) A flat handle with a handle that is always housed in the same plane as the door surface is often attached to the door of the box type mentioned above, but conventional flat handles of this type are Usually, when the button was pressed, the handle was raised by a spring, and at the same time the locking plate was rotated to unlock the door. For this reason, a passerby may accidentally press the push button to unlock the door, and since the spring for lifting the handle is installed between the handle and the main body, it is troublesome to assemble, and Since the upper spring is exposed to the outside of the main body, it also has the disadvantage of being susceptible to rust when used in outdoor boxes.

(Problems that the invention attempts to solve) This invention solves these conventional problems,
The purpose is to create a flat handle that will not be unlocked even if the push button is pressed by mistake, is easy to assemble, and will not cause the handle spring to rust due to rainwater when used outdoors. It was completed as.

(Means for solving the problem) The present invention has a cylindrical bearing part protruding from the upper back surface of a vertically long main body that is fixed to the door of a box, etc., and a lock plate is installed at the rear end of the bearing part. A shaft with a pin for attaching a handle is housed at the front end of the shaft, and the pin at the front end of the shaft has a flat plate-like mounting part that covers the front surface of this pin and the handle jump spring wound around it. The handle is pivotally mounted, and a hook lever is provided at the lower part to engage with the tip of the handle and hold the handle in a state housed inside the main body.

(Embodiment) Next, the present invention will be described in detail with reference to the illustrated embodiment. Reference numeral 1 is a vertically long main body fixed to the door of a box, and this main body 1 has a shallow recess 2 for storing a handle on the front. Also, a cylindrical bearing portion 3 is provided protruding from the upper back surface. A shaft 5 having a locking plate 4 at its rear end for engaging with the main body of a box or the like and a rotation angle regulating plate 6 are housed inside the bearing portion 3. The shaft 5 is equipped with a protrusion 7 having a central angle of approximately 90° as shown in FIG. 8. Therefore, the shaft 5 can only rotate within the range of about 90° allowed by the notch 8 of the rotation angle regulating plate 6. In addition, by changing the mounting angle of the rotation angle regulating plate 6 with respect to the bearing part 3, the fourth
It has a structure that can be used for both the right-hand swinging door shown in the figure and the left-hand swinging door shown in FIG.

On the other hand, a bifurcated protrusion is formed at the front end of the shaft 5, and a handle attachment pin 9 is supported between these protrusions. A handle spring 10 and a handle 11 are attached to this pin 9. This handle 11 is connected to a recess 2 on the front surface of the main body 1.
The mounting part 12 at the upper end covers the front surface of the pin 9 and the spring 10 for jumping up the handle, and is structured to prevent rainwater from entering these parts. Note that 13 is an O-ring for preventing rainwater from entering. Further, in this embodiment, a key 14 is attached to the lower part of the main body 1 at a position covered by the handle 11. The key 14 is provided with a lock bar 15 at its rear portion, and the upper end of the lock bar 15 is configured to pass through a through hole in the bearing portion 3 and engage with a recess 16 in the shaft 5.
The shaft 5 becomes rotatable only when the lock bar 15 is pulled down by the key 14, and the shaft 5 is normally locked by the lock bar 15.

Reference numeral 17 denotes a hook lever pivotally mounted on the front surface of the lower end of the main body 1, and is normally urged by a spring 18 to engage with the lower end of the handle 11, so that the handle 11 is attached to the lower end of the main body 1.
It is held in the recess 2 of. This spring 18
is housed inside the hook lever 17 to prevent rainwater from splashing on it.

(Function) The device configured in this way always has handle 11.
is housed in the recess 2 of the main body 1, and its lower end is locked by the hook lever 17, and at this time, the locking plate 4 at the rear end of the shaft 5 engages with the main body of the box to close the door. It's locked. At this time, shaft 5
Since the handle attachment pin 9 and handle jump spring 10 provided on the handle are covered in front by the attachment part 12 of the handle 11, these parts are protected from rainwater even when used outdoors. Never rusts. Also, if you want to open the door, press the hook lever 17 with your fingertip to release the engagement with the handle 11, and the handle 1
1 jumps forward due to the action of the handle jump spring 10, so operate the exposed key 14 to lower the lock bar 15, and then rotate the handle 11 about 90 degrees around the shaft 5 to release the lock plate. You can now open the door by rotating 4. In this way, with the flat handle of the present invention, the door cannot be opened simply by pressing the catch lever 17 and flipping up the handle 11; however, in the case of the flat handle provided with the key 14 as in the embodiment, the door must be opened after operating the key 14. Rotate the handle 11 with the button, and also rotate the handle 11 by hand even if the key 14 is not available.
The door cannot be opened unless it is rotated 90 degrees, which prevents the door from being opened accidentally like in the past.

In addition, the flat handle of the present invention can be assembled into the bearing part 3 of the main body 1 after the spring 10 for lifting the handle and the handle 11 are assembled into the pin 9 of the shaft 5, which facilitates the assembly process. There are also advantages.

(Effects of the invention) As is clear from the above explanation, the present invention prevents the door from becoming unlocked even if the hooking lever is pressed by mistake, is easy to assemble, and has a spring for lifting the handle. Since the part is covered by the handle attachment part, the spring will not rust due to rainwater even when attached to an outdoor box. Therefore, the present invention has extremely great practical value as a flat handle that solves the problems of the conventional handle.
