DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a flat handle device used for a door of a switchboard or the like.

[Conventional technology]

Switchboards, etc. are dimly lit away from lighting equipment,
It is often installed in a cluttered power room or the like, and if a large door opening / closing handle sticks out on the surface of a switchboard door or the like, a passerby may hit the handle and get injured.

Therefore, like a switchboard, inspection door or emergency door,
Doors that can be opened and closed only by a specific person or small doors that are not frequently opened and do not require force to open and close are manufactured so that protrusions such as door opening and closing handles do not protrude from the door surface. .

The flat handle device is provided on such a door. When the door is not opened and closed, the handle can be put into the door, and when the door is opened and closed, the handle can be projected to a usable state by a simple operation.

As a conventional technique of the flat handle device, there is an actual exploitation of Shokai 58-3572.
There is a technique described in Japanese Laid-Open Publication No. Sho-37-37864.

FIG. 12 and FIG. 13 are longitudinal sectional views showing a flat handle device disclosed in Japanese Utility Model Laid-Open No. 64-37864, in which a handle main body 3 is pivotally attached to an orthogonal pivot 2 provided in a case 1 and is orthogonal. One end of the spring 4 wound around the pivot 2 has a handle body 3
The other end of the handle body 3 is pressed against the case 1 to urge the handle body 3 in a direction projecting from the case 1, and the receiving portion 5 is provided at the end of the handle body 3 in a protruding manner.

Below the receiving portion 5, a spring 7 is elastically mounted between the case 1 and a push button 6 provided to be retractable in the case 1, and the push button 6 is biased in a direction projecting from the case 1.

The latch body 8 provided in the case 1 so as to be movable up and down has a locking protrusion 9 that can be engaged with and disengaged from the receiving portion 5, and an inclined surface 11 that comes into contact with the ball 10 accommodated in the push button 6. A spring 12 elastically mounted between the latch body 8 and the case 1 urges the spring upward, and when the handle body 3 is housed in the case 1, the receiving portion 5 is locked by the locking protrusion 9, The operating protrusion 13 extended to the main body 3 pushes the upper edge of the hole 15 of the stopper plate 14 pivotally attached to the case 1, the stopper plate 14 engages with the fixed frame side, and the door is locked. (See Figure 12).

When the push button 6 is pushed to the fingertip in such a door locked state, the inclined surface 11 is pushed downward via the ball 10 and the latch body 8 is lowered to disengage the locking protrusion 9 from the receiving portion 5, The handle main body 3 whose engagement with the portion 5 is released protrudes from the case 1, and the operating protrusion 13 abuts on the lower end edge of the hole 15.

When a fingertip is put on the protruding handle main body 3 and further rotated in the protruding direction, the stopper plate 14 pushed by the operating protrusion 13 rotates to separate from the fixed frame side to unlock the door. The door is opened as it is by the force of the fingertip applied to the handle body 3 (see FIG. 13).

[Problems to be solved by the device]

As described above, when the push button 6 is pushed with the fingertip, the handle body 3 that has been immersed in the case 1 suddenly pops out due to the elastic force of the spring 7.

Since the position of the fingertip that presses the push button 6 and the tip of the handle body 3 are extremely close to each other, there is a risk of being injured by being hit by the protruding handle.

In order to prevent this danger, the push button 6 and the latch body 8
Is provided on the upper end of the handle body 3 above the orthogonal pivot 2, the fingertip for operating the push button 6 moves away from the protruding side end of the handle body 3, so there is no risk of tapping the hand, but the rotation of the handle body 3 Orthogonal pivot 2 which is the center to latch body 8
The distance to the door becomes shorter, and due to a manufacturing dimensional error of the latch body 8 and parts near the latch body 8, the door surface and the surface of the depressed handle body 3 are not aligned with each other, and a step is likely to occur, and the appearance of the door is impaired. Occurs.

The present invention is intended to solve such a problem, and the handle body that pops out when the handle body housed in the case is operated to protrude without damaging the appearance of the door. (EN) Provided is a flat handle device which has no risk of colliding with the handlebar and which does not cause a step on the surface of the handle without lengthening the upper end of the handle.

[Means for Solving the Problems]

In order to achieve the above object, the flat handle device of the present invention comprises a case having an opening at the substantially central portion of the surface, and an eccentric protrusion fitted on one side of the case and provided at the end by manual operation. A rotating member that moves, a support shaft that is fixed to one side of the case in the opening, one end is pivotally attached to the support shaft, and an operating protrusion is bent from the one end and the other end is provided. A handle to open and close the opening, a spring for biasing the other end of the handle in a direction projecting from the opening, and one end slidably provided in the case. A lock plate that abuts on the eccentric projection, and a locking portion provided on the other end engages and disengages with the locked portion, and one end of the lock plate abuts on the eccentric projection, and the locking portion covers the locked portion. A spring for urging the engaging portion in a direction to engage the locking portion, and the spring pivotally attached to the case. A dead plate that engages with the moving projection and has a tip portion fitted into and removed from a receiving bracket of the door frame, and the lock plate whose one end is pushed by the eccentric projection has the locking portion and the locked portion. Of the eccentric projection, instead of the rotating member having the eccentric projection, is inserted into a hole provided in the case and protrudes from the surface of the case. The inclined surface is provided at the end of the pushing member biased in the direction,
It is also possible to urge one end of the lock plate slidably provided in the case in the direction of abutting against the inclined surface.

[Action]

The operation of the flat handle configured as described above is as follows.

(Locked state) The handle that is recessed in the opening of the case is in a state in which the locked part is locked by the locking part of the lock plate and is prevented from protruding from the case, and engages with the operating protrusion. The dead plate is fitted in the frame side.

(Unlocking operation) When the rotating member is rotated, the eccentric protrusion of the rotating member pushes the lock plate, and the locked portion of the pushed lock plate is disengaged from the locked portion of the handle, and the lock plate is released. The handle released from the block is rotated in the urging direction to project from the opening of the case so that it can be operated, and the rotated operation protrusion moves in the hole of the dead plate.

Since the handle protrudes on the opposite side of the rotating member, the hand for operating the rotating member is not hit by the handle.

When the handle is further turned by hand after unlocking, the operating projection pushes the dead plate, and the dead plate is released from the frame side and unlocked.

In a flat handle device using a pushing member having an inclined surface instead of a rotating member having an eccentric projection, when the pushing member is pushed, the inclined surface pushes the lock plate, and the locking portion of the pushed lock plate is pushed. Is released from the locked portion of the handle, and the same operation is performed.

Also at this time, since the handle protrudes on the opposite side of the pushing member, the hand for operating the pushing member is not hit by the handle.

The other items are the same as those in the above-described embodiments.

[Effect of device]

Since the present invention is configured as described above, since the handle immersed in the case is locked on the side opposite to the rotation fulcrum, the position error of the surface of the locked handle is small and the handle surface is almost completely removed from the case surface. It is possible to eliminate the conventional drawback of hitting a hand with a protruding handle while maintaining the conventional advantage of being able to match.

That is, when the rotating member or the pushing member is operated, the handle end portion on the opposite side of the rotating member or the pushing member is projected, so that there is no danger of the operating hand being hit by the protruding handle end portion, which is extremely safe. It became a flat handle device with high flexibility.

One end of the handle is pivotally attached to the support shaft fixed to one side of the case, and the locked part provided on the other end of the handle is engaged with and disengaged from the locking part of the lock plate. Becomes extremely short.

Therefore, there is an advantage that the case can have a compact structure with a short overall length.
