In the above-described flat handle device, for example, when a packing is interposed between the door and the box body, in the closed state, the door receives a resilient force that is pushed back in the releasing direction by the packing. On the other hand, since the hook plate is rotationally biased in the direction in which the hook plate is engaged with the receiver, the hook plate and the receiver are pressed and held in a state where the hook plate is insufficiently engaged with the receiver. A so-called half-locked state may occur. If vibration is applied in the half-locked state, the door may be opened carelessly. In particular, in an in-vehicle generator, if the door is opened carelessly while the vehicle is traveling, a serious accident may occur, so it is necessary to check the locked state of the flat handle device before traveling.
However, in the above-described conventional flat handle device, since the spring for rotating and biasing the operation handle in the lying down direction is provided between the operation handle and the housing, the hook plate is not sufficiently engaged with the receiving plate. Even in the locked state, the operation handle does not get up from the front concave portion of the housing and is in a state of being laid down in the front concave portion by the biasing force of the spring. For this reason, the half-lock state cannot be confirmed from the appearance of the operation handle, and there is a problem that it is difficult to avoid the half-lock.
Accordingly, an object of the present invention is to provide a flat handle device in which the operation handle rises from the front concave portion of the housing in the half-locked state, and the half-locked state can be easily confirmed in appearance. .

  In order to solve the above-described problem, the flat handle device according to this application includes a base end portion of the operation handle 5 that is fitted in a front recessed portion 4 of the housing 3 that is fitted and fixed in a mounting hole 2 formed in the door 1 so as to be raised and lowered. Is pivotally attached to the housing 3, and the base end of the hook plate 8 that engages and disengages with the receiver 7 on the box body 6 side is pivotally attached to the housing 3, and the spring 9 that rotates and biases the operation handle 5 in the upright direction is operated. A spring 10 that is mounted between the handle 5 and the housing 3 and that is provided between the hook plate 8 and the housing 3 with a spring 10 that rotates and biases the hook plate 8 in a direction that engages with the receiver 7, and is detached from the receiver 7. A drive plate 11 for pulling the hook plate 8 is provided on the back side of the operation handle 5, and the spring 10 is set to have a spring force larger than that of the spring 9, so that the operation handle 5 is always in the lying down direction via the drive plate 11. Rotating bias, hook plate 8 When rotating in a direction to be released from the receiver 7 by being pushed by the gold 7, the rotation urging force of the spring 10 against the operation handle 5 is cut off, and the operation handle 5 is erected by the rotation urging force in the standing direction by the spring 9. The half-locked state can be visually confirmed by lifting from the front concave portion 4 of the operation handle 5.

According to the planar handle device of the invention according to this application, the spring force of the spring 10 that rotationally biases the hook plate 8 in the direction to engage the receiver 7 from the spring 9 that rotationally biases the operation handle 5 in the standing direction. Is set so that the operation handle 5 is normally rotated and biased by the force of the spring 10 via the driving plate 11 in the lying down direction so that the hook plate 8 is pushed by the receiver 7 and is released from the receiver 7. When the spring 10 is compressed by rotating in the direction, the rotation biasing force of the spring 10 against the operation handle 5 is cut off, and the operation handle 5 is rotated in the standing direction by the rotation biasing force of the spring 9 in the standing direction. When the operating handle 5 is lifted from the front concave portion 4 in the state, this can be easily visually confirmed.
If the outer surface of the operation handle 5 that is not exposed by being immersed in the front recess 4 of the housing 3 in the lying state is colored with a warning color such as a fluorescent color that can be clearly distinguished from the color of the peripheral member, Due to the exposure, the floating of the operation handle 5 from the front recess 4 can be more easily visually confirmed.

Embodiments of the present invention will be described with reference to the drawings.
In the illustrated embodiment, the operation handle 5 includes a front plate portion 5a that forms a flat surface continuous with the front surface of the housing 3 in a lying state, and a pair of side plate portions 5b that refract at right angles from both sides of the front plate portion to the back side. And have. The driving plate 11 has a bent end portion 11 a welded to the center line of the back surface of the operation handle 5. The side surface of the drive plate 11 that faces the transverse pivot 15 is formed as an arc surface 11b with the transverse pivot 15 as the center of curvature. The drive projection 11c formed at the tip of the circular arc surface 11b engages with the passive projection 8a provided on the hook plate 8 side, so that the hook plate 8 is pulled by the drive plate 11 when the operation handle 5 is pulled out. It has become so. At the tip of the hook plate 8, a cam slope 8 b that abuts on the metal receiver 7 when the door 1 is closed and rotated is formed. The hook plate 8 temporarily retracts and rotates counterclockwise when the metal receiver 7 relatively pushes the cam slope 8b. The receiver 7 is formed in a pin shape, and the hook plate 8 is formed with a receiving groove portion 8c into which the receiver 7 is inserted continuously from the end portion of the cam inclined surface 8b.

  The operation handle 5 and the hook plate 8 are pivotally attached to the housing 3 by a common transverse pivot 15, and the transverse pivot 15 is arranged parallel to the front surface of the housing 3. An enlarged head 15 a is formed at one end of the transverse pivot 15, and a retaining ring 19 is fitted in the annular groove 15 b at the other end of the transverse pivot 15.

  The stand-up biasing spring 9 of the operation handle 5 is constituted by a torsion coil spring and is housed inside one rear raised portion 14 of the housing 3. The coil portion 9 a of the spring 9 is fitted on the transverse pivot 15, one end portion 9 b is in contact with the back surface of the operation handle 5, and the other end portion 9 c is in contact with the inner bottom surface of the back raised portion 14.

  The return urging spring 10 of the hook plate 8 is formed of a torsion coil spring and is housed in the back recess 13 of the housing 3. The coil portion 10 a of the spring 10 is fitted to the transverse pivot 15, the linear end portion 10 b is in contact with the outer bottom surface of the back recess 13, and the intermediate U-shaped bent portion 10 c is opposite to the cam slope 8 b of the hook plate 8. Is in contact with the side surface 8d. The spring force of the spring 10 is set to be larger than the spring force of the urging / biasing spring 9 of the operation handle 5, and the urging force of the operation handle 5 is always canceled out and the operation handle 5 is laid down via the drive plate 11. Rotating bias in the direction.

  When the operation handle 5 is in a lying state, a fluorescent color tape 5c is attached to the outer side surfaces of the pair of side plate portions 5b of the operation handle 5 which are not exposed by being immersed in the front recess 4 of the housing 3, The alarm color is clearly distinguishable from the color. Due to the exposure of the alarm color, the lifting of the operation handle 5 from the front recess 4 can be easily visually confirmed. A lock unit 20 such as a cylinder lock is attached to the tip of the operation handle 5. A metal plate 21 is welded to the inner bottom surface of the front recess 4 of the housing 3.

  A stopper plate 23 is connected to the tip of the rotor 22 of the lock unit 20. When a predetermined key (not shown) is inserted into the key hole 25 of the rotor 22 and the rotor 22 is rotated by a predetermined angle, the stopper plate 23 is engaged with the bent tip 21 b of the receiving plate 21, and the operation handle 5 is attached to the housing 3. It is locked at a position immersed in the front recess 4. Since the base end portion 21 a of the clasp plate 23 is welded to the inner bottom surface of the back recess 13, an opening 21 c having the same shape as the opening 12 is formed to allow the operation handle 5 to penetrate the drive plate 11. It is.

  The packing member 17 is fixed to the back surface of the front plate portion 5a of the operation handle 5. When the operation handle 5 is in the lying position, the packing member 17 is brought into close contact with the peripheral portion of the opening 21c of the clasp plate 21, thereby The opening 12 is indirectly closed. When the clasp plate 21 is not welded, the packing member 17 closes to the inner bottom surface of the back recess 13 that is the peripheral portion of the opening 12c when the operation handle 5 is in the lying position. 12 is directly occluded.

  As shown in FIG. 3, when the door 1 is closed and locked, the hook plate 8 is engaged with the metal receiver 7, and this engaged state is held by the rotation bias of the spring 10. The operation handle 5 is urged to rotate in the erection direction by an urging spring 9, and the driving urging force of the spring 10 having a stronger spring force engages with the passive protrusion 8 a of the hook plate 8. 11 is transmitted to the operation handle 5 via 11, and the operation handle 5 is held down in the front recess 4 of the housing 3. To unlock the door 1 by unlocking the box 6 of the door 1, the operator inserts his hand into the front recess 4 of the housing 3, puts his finger on the tip of the operation handle 5, and crosses the operation handle 5. With the pivot axis 15 as the center, it is erected and rotated counterclockwise in FIG. The drive plate 11 of the operation handle 5 pulls the hook plate 8 against the urging force of the spring 10 through the passive protrusion 8a and rotates it counterclockwise about the transverse pivot 15. By this rotation, the hook plate 8 is detached from the receiver 7 as shown in FIG. 5, so that the lock of the door 1 to the box body 6 is released, and the door 1 is opened by pulling the operation handle 5 forward. .

  When the finger is released from the operating handle 5 after the door 1 is opened, the operating handle 5 rotates clockwise around the transverse pivot 15 integrally with the hook plate 8 in FIG. It returns to the state where it is immersed in the front recess 4. The hook plate 8 returns to a position where the tip is perpendicular to the back surface of the housing 3.

  When the door 1 is closed and rotated about the hinge shaft at one end (not shown) after refueling or checking the diesel generator in the box, the tip of the hook plate 8 is moved near the end of the closing operation. Abuts on the receiver 7. When the door 1 is further closed, the hook plate 8 is pushed relative to the receiver 7 and rotates around the transverse pivot 15 by a predetermined angle in the counterclockwise direction. At the moment when the door 1 is completely closed and the engaging portion of the hook plate 8 with the receiver 7 faces the receiver 7, the hook plate 8 is rotated clockwise by the bias of the spring 10, Engage. Thus, when the door 1 is closed and locked with respect to the box main body 6, the opening part 12 of the housing 3 is obstruct | occluded by a part of the operation handle 5, and a waterproof function and a sound insulation function will express.

Now, for example, as shown in FIGS. 6 and 7, the door 1 receives a resilient force that is pushed back in the releasing direction by a packing (not shown), and the hook plate 8 is not sufficiently engaged with the receiver 7. The so-called half-locked state that is maintained in this state occurs, for example, when the rotational biasing force of the hook plate 8 and the elastic force of the packing are balanced. In the closing operation process so far, the hook plate 8 compresses the spring 10 and rotates counterclockwise by a predetermined angle from a position perpendicular to the back surface of the housing 3. However, since the passive protrusion 8a cannot push the driving plate 11 counterclockwise, the counterclockwise rotation of the hook plate 8 is transmitted to the driving plate 11 and the operation handle 5 via the passive protrusion 8a. There is nothing. For this reason, in the conventional flat handle apparatus described in Patent Document 1, the passive protrusion 8a and the drive plate 11 are separated from each other, and the operation handle 5 is in a lying state.
However, in this embodiment, the operation handle 5 is independently urged to rotate in the standing direction by the spring 9, so that the drive plate 11 is rotated upright by a predetermined angle while being engaged with the passive protrusion 8a. A part of the surface rises from the front recess 4. At this time, since the colored portion by the fluorescent color tape 5c on the outer surface of the operation handle 5 is exposed, the operator can easily visually check the half-locked state and correct it.
