[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle device used for locking and opening a door panel in a switchboard storage box or the like. When the handle device is not used, the handle is housed so as to be buried in the case. The present invention relates to a flat handle device which has substantially the same plane.

[0002]

2. Description of the Related Art A flat handle device of a type in which a handle is housed so as to be buried in a case when not in use, and the handle is rotated and erected from the case when used, and the door panel is opened by gripping and rotating the handle. For example, the one disclosed in Japanese Utility Model Publication No. 4-36164 is known. In this flat type lever handle device, the handle is divided into two members, one member is pivotally attached to both side walls of the case by a transverse pivot, and the other member is rotatably engaged with the one member, In addition, by connecting to the locking shaft extending in the front-rear direction, both the upright rotation operation of the handle and the rotation operation of the locking shaft by the rotation of the handle are possible.

[0003]

In the above-mentioned conventional flat handle device, in particular, the handle is composed of two members,
Since each of them is configured to operate separately, there is a problem that the mechanism is complicated, large and expensive.

Therefore, it is an object of the present invention to provide a flat handle device which allows a handle to be rotated easily and accurately, has a relatively simple structure, can be miniaturized, and can be obtained at low cost. I am trying.

FIG. 7 is a side view in which a part of the flat handle device is raised, and FIG. 7 is a front view in which the handle of the flat handle device is rotated. FIG. 9 is a flat handle device. FIG. 1 is an exploded perspective view of essential parts.
Reference numeral 0 is a perspective view of the flat handle device in a mounted state.

As shown in FIG. 10, for example, the flat handle device 31 is mounted on the door B of the storage box A of the switchboard by attaching the mounting bracket 3 to the door B.
It is fixed with a bolt 33 using 2.

As well shown in FIG. 1, a locking shaft rod 3 is rotatably pierced through a cylindrical portion 2 at an upper portion of the case 1 so as to extend in the front-rear direction. Collar 1 in the middle of the locking shaft 3
A packing 14 is fitted in the ring 3 and is in contact with the inner circumference of the cylindrical portion 2. Square shaft portion 4 at the rear of this locking shaft rod 3
Is projected to the rear side of the cylindrical portion 2, a stopper cam 5 and a stopper plate 6 are fitted therein, and fixed by bolts 7. The stopper plate 6 engages with or disengages from an engaging portion (not shown) of the storage box A depending on its rotational position.

As shown in FIG. 5, the stopper cam 5 is provided with cam surfaces 8 and 9 at positions separated from each other by 180 ° in the rotational direction. A stopper projection 10 is provided on the rear surface of the cylindrical portion 2, and stopper surfaces 11 and 12 are formed on both sides of the stopper projection 10 so as to form an angle of 90 ° with each other in the rotation direction. By contacting the cam surfaces 8 and 9 of the stopper cam 5 with the stopper surfaces 11 and 12 of the stopper protrusion 10, the rotation range of the locking shaft 3 is regulated to 90 °. Therefore, by shifting the mounting angle of the stopper cam 5 with respect to the square shaft portion 4 by 90 ° in the rotation direction, the locking shaft 3
The rotatable direction of can be changed to right or left.

The handle 16 accommodated in the accommodating space 15 of the case 1 is pivotally attached to the front end of the locking shaft rod 3 by a pivot 17 penetrating the handle 16 in the orthogonal direction at the base end. . A push-in projection 18 is provided on the front surface side of the base end portion of the handle 16 for rotating the handle 16 about a pivot 17 so as to stand up. The pushing projection 18 projects toward the front side of the case 1 in the state shown in FIGS. 1, 4, and 6 in which the handle 16 is laid down in the housing space 15. On the rear surface side of the base end portion of the handle 16, a first plane 1 parallel to the front surface of the handle 16 is provided.
9 and a second plane 20 which forms an angle of approximately 135 degrees to it.

A spring 21 and a spring bearing member 22 are provided between the handle 16 and the collar 13 of the locking shaft 3. The spring receiving member 22 is prevented from rotating with respect to the case 1 by a rotation preventing protrusion 23. As shown in FIGS. 6 and 7, the front surface of the spring receiving member 22 is always in contact with the first flat surface 19 or the second flat surface 20 of the handle 16 by the spring force. That is, in a state where the handle 16 is laid down in the accommodation space 15, the front surface of the spring receiving member 22 abuts on the first flat surface of the handle 16 and the handle 16 is erected from the case 1. In the state of 7, the front surface of the spring bearing member 22 is in contact with the second flat surface of the handle 16. On the front surface of the spring bearing member 22, horizontal and vertical pin receiving grooves 24 and 25 are formed which are orthogonal to each other. Then, the pin 26 penetrating the locking shaft rod 3 in the direction orthogonal to the pivot 17 falls into one of the pin receiving grooves 24 and 25 depending on its rotational position, and the handle 1
6 is held in a horizontal or vertical position.

A cylinder lock, which is located near the tip of the handle 16 and serves as a lock mechanism 27 for locking the handle 16 to the case 1, is attached to the lower portion of the case 1. With the cam 28 of the cylinder lock 27 pushing up the latch member 29, the latch member 29 engages with the engaging portion 30 of the handle 16 and the handle 16 is locked to the case 1.

In the flat handle device 31 of this embodiment, the handle 16 is released from the case 1 by inserting a key (not shown) into the lock mechanism 27 of the case from the locking position shown in FIG. To do. In this state, the front surface of the spring receiving member 22 is in contact with the first flat surface 19 of the base end portion of the handle 16 to maintain the handle 16 in the lying state. In this state, when the pushing protrusion 18 of the handle 16 is pushed in with a finger, the handle 16 pushes the spring receiving member 22 backward and compresses the spring 21, while rotating around the transverse pivot shaft 17. When the handle 16 rotates by a predetermined angle, the spring 21 recovers beyond its compression dead point, and the handle 16 automatically stands up. Then, this time, the second plane 20 comes into contact with the front surface of the spring bearing member 22, and the handle 16
Acts to maintain the standing state of. When the upright handle 16 is gripped and rotated by 90 ° as shown in FIG. 8, the locking shaft 3 rotates together with the stopper plate 6, and the cam surface 9 of the stopper cam 5 becomes the stopper surface 12 of the stopper protrusion 10. Abut and stop, and the pin 26 receives the pin receiving groove 2
4 to maintain the sideways state of the handle 16. In this state, the lock on the box A can be released and the door B can be opened.

When the door B is closed and locked, the handle 16 is grasped and oriented in the vertical direction so that the stopper plate 6 is oriented in the locking direction. At this time, the cam surface 8 of the stopper cam 5 comes into contact with the stopper surface 11 of the stopper projection 10 and stops, and the pin 26 falls into the pin receiving groove 25 to maintain the handle 16 in the vertically oriented state. In this state, the handle 16 is made to fall into the space 15 of the case 1. Then, the key is inserted into the lock mechanism 27 of the case to perform the locking operation. The latch member 29 of the locking mechanism 27 engages with the engaging portion 30 of the handle 16 to lock the handle 16 in the case 1.
