Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a round flat handle which is used by being attached to a door of a box for storing electric equipment such as a control panel and a distribution board.

[0002]

2. Description of the Related Art A conventional round plane handle is usually a circular concave body to which a handle having a shaft at its center is rotatably attached. Therefore, in order to lock the handle in order to prevent it from being operated by an outsider, a lock for locking the handle must be incorporated in the round flat handle itself.

[0003]

However, in such a conventional device, when it is used in a place where locking is unnecessary, the lock for locking is excessive and the manufacturing cost is increased accordingly. However, if a lock is not provided, the two types of round flat handles will be manufactured and stored, which will also increase the cost. Therefore, there has been a long-awaited demand for a round flat handle that does not have a lock on the round flat handle itself and can be locked with a padlock or a code lock only when locking is required.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a shaft hole portion is provided at the center of the rear plate portion of a handle body having a round concave shape. When a substantially central portion of the handle portion is tiltably supported on the front end surface of the shaft that is pivotally supported in the hole portion, and when the tip of the handle portion tilts toward the rear plate portion of the inner peripheral surface of the handle body. A stopper is provided facing the front end side surface of the handle portion, a locking hole is provided in a vertical plate portion stretched at the base end of the handle portion, and a lock rod inserted into the lock hole is provided on the front end surface of the shaft. It is characterized in that a lowering stop portion that comes into contact therewith is provided.

[0005]

The round flat handle of the present invention is used by mounting the round concave handle body in the mounting hole formed in the door, and the handle portion pivotally supported on the front end face of the shaft is not tilted. Then, the handle can be freely rotated without being obstructed by the stopper. Therefore, the locking plate attached to the base end of the shaft can be unlocked and locked by rotating the handle.

Further, in the round flat handle of the present invention, when the handle portion is tilted and a lock rod such as a padlock is inserted into the lock hole to lock the lock rod, the lock rod is pushed down to the rear plate side. Movement will be restricted. For this reason, the handle portion keeps the tilted state, and the tip side surface of the handle portion comes into contact with the stopper, so that the rotation of the shaft is prevented and the handle can be locked accurately.

[0007]

Embodiments of the present invention will now be described in detail with reference to the illustrated embodiments. Reference numeral 1 denotes a circular shallow concave handle body, and the handle body 1 is provided on the outside of the front end in a mounting hole of a door 30 of a box for storing electrical equipment such as a control panel and a distribution board as shown in FIGS. 3 and 6. It is screwed using a stretched ring-shaped collar plate. 2 is a rear plate portion 3 of the handle body 1
The short cylindrical shaft holes 4 provided in the shaft shaft 4 are rotatably supported by the shaft hole 2. An angular projection 5 is provided on the rear end surface of the shaft 4, and a locking plate 31 that engages with a locking portion of a box for storing electrical equipment is attached to the angular projection 5.

The shaft 4 of the embodiment is formed with a small diameter on the rear end side to prevent the shaft 4 from coming off from the rear plate portion 3 side. Further, the shaft 4 is provided with a notch 6 on the base end peripheral surface of the large-diameter shaft portion on the front end side over approximately 270 °, and the notch 6 is provided on the inner peripheral surface of the shaft hole portion 2 at approximately 180 °. It is fitted to the convex portion 7 and is regulated so that it can be rotated only about 90 °. The door 30 of this embodiment is a right-opening door, and is a collar portion 2 of the handle body 1.
The marking 23 of 2 is printed at a position of 90 ° to the right from above, but for use in a left-opening door, the mounting direction of the handle body 1 is changed by 90 ° so that the marking 23 of the collar portion 22 of the handle body 1 is up. It is only necessary to change the mounting direction of the lock plate 31 by 180 ° so that the lock plate 31 is at a position of 90 ° to the left, and it can be used for both the right and left doors.

Reference numeral 8 is a handle portion. The central portion of the handle portion 8 is tiltably supported by a bearing plate portion 9 stretched on the front end surface of the shaft 4. In this embodiment, as shown in FIGS. 1 and 5, the upper portions of the facing surfaces of the two bearing plate portions 9, 9 are formed into thick portions 9a, 9a, and the thick end portions 9a, 9a are provided on the base end side. The semicircular concave bearing portions 9b, 9b are provided on the
b, 9b are fitted with supporting shaft portions 11, 11 projecting on both surfaces of a shaft plate portion 10 projecting on the rear surface side of the central portion of the handle portion 8, and between the shaft plate portion 10 and the shaft 4. The coil-shaped push spring 12 is interposed between the shaft and the shaft.

Reference numeral 16 is a stopper provided on the rear plate portion of the inner peripheral surface of the handle body 1, and does not hinder the rotation of the handle portion 8 when it is in a normal state. However, this stopper 16
Is a locking plate attached to the base end of the shaft 4 when the tip of the handle portion 8 is tilted toward the rear plate portion, and is located on the side surface of the tip of the handle portion 8 to prevent the handle portion 8 from rotating. 31 is fixed to the locking position.

Reference numeral 17 is a locking hole provided in a vertical plate portion 18 stretched at the base end of the handle portion 8, and 19 is a lowering stop portion provided on the front end surface of the shaft 4. As shown in FIG. 6, the stopper 19 prevents the lock bar 21 from moving toward the rear plate when the lock bar 21 such as a padlock or a code lock 20 is inserted into the lock hole 17 and locked. It is for. As a result, the handle portion 8 is held in a tilted state, and the tip end side surface of the handle portion 8 abuts the side surface of the stopper 16 to prevent rotation. The stopper of this embodiment can be used for both the right-opening door and the left-opening door.
Also, a right-opening door stopper 16a and a left-opening door stopper 16b are provided at two positions on the rear plate of the inner peripheral surface of the handle main body 1 at 90 ° intervals so as to correspond to the right-opening door and the left-opening door. If the handle is locked in the state shown in FIG. 2, the locking plate 31 can be kept in the unlocked position.

The round flat handle having the above-described structure is provided in a state where the handle portion 8 is not tilted as shown in FIG.
The handle portion 8 can be freely rotated without being obstructed by the stopper 16. However, after tilting the handle portion 8 as shown in FIG. 6, a lock rod 21 such as a padlock is inserted into the locking hole 17
If the lock rod 21 is inserted into the lock and locked,
The movement to the rear plate portion side is regulated by 9 and the tilted state is maintained, and the tip end side surface abuts on the stopper 16 and the shaft 4
Is prevented from rotating. Therefore, the door 30 is locked.

[0013]

As is apparent from the above description, the present invention allows the handle to be locked with a padlock, a code lock, etc., and a padlock, code lock, etc. are prepared only for those requiring locking. Therefore, the manufacturing cost can be reduced. Therefore, the present invention is a great solution to the industry as a solution to the problem of the conventional round flat handle.
