Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a door handle device in which a main lever can be operated by forming an insertion opening into which a finger can be inserted by operating a sub-member. It is about improvement.

(Prior Art) As shown in FIG. 1, a sub-member 2 biased counterclockwise by a spring 1 is pushed against the biasing force of a spring l to a position indicated by a dashed line. There is one in which the main lever 3 is pulled up to unlock the door.

(Problem to be Solved by the Invention) However, in such a device, when the main lever 3 is pulled up with one's fingers and then returned, the sub member 2 is already under the biasing force of the spring 1. Since the lever returns to its original position, the finger gets caught between the main lever 3 and the sub member 2, which is very troublesome and also dangerous.

The present invention has been made in view of the above problems, and when the main lever is returned to the insertion opening formed by the operation of the sub-lever, a blocking means is provided to prevent the main lever from returning in the middle of the return operation. A door handle device is provided in which the main lever closes by returning to its original position after a predetermined period of time has elapsed, thereby preventing fingers from being caught between the main lever and a sub member or the main lever and a base, etc. is intended to provide.

(Means for Solving the Problems) In order to solve the above problems, in the present invention, by operating the sub-member, an insertion opening into which a finger can be inserted is formed, and the main lever can be operated. In the door handle device, a blocking means for preventing the main lever from returning during the return operation of the main lever, a release member for releasing the blocking means to enable the main lever to return, and a release member that responds to the return operation of the main lever. The basic feature is that the device further includes a delay means for driving the release member after a predetermined time delay.

(Function) According to the present invention, when the main lever is returned to its original position, the main lever is held with the finger insertion hole formed in the middle position, and after a predetermined period of time, the main lever returns to its original position. Because of this, when you return the main lever to its original position, your fingers won't get caught and the operation feels good.

The other ends of the first contact 9a and the second contact 9b are both connected to the power source B+.

Next, the operation of this embodiment will be explained.

First, when the sub member 16 is pushed in, the sub member 16 rotates clockwise about the support 7 as the center of rotation against the biasing force of the spring I8. By doing so, an insertion opening into which a finger can be inserted is formed. Then, when you insert your finger and pull the main lever 5, the main lever 5 rotates clockwise about the shaft 6 in FIG.
The i-th contact 9a is turned on. First contact 9
When a turns on, current flows from the power supply B+ to the ground through the first contact 9a, low resistors R1, R2, and R3, and the negative comparator 51CI becomes "high", but the other comparator IC becomes "high".
Therefore, the connection point PI between the negative comparator ICI and the other comparator 102 outputs a low signal. That is, at this time, the first contact 9a, the second contact 9b, and the capacitor CI.

- Comparator ICI, other comparator IC2, connection point between - comparator ICI and other comparator IC2! The voltage of the transistor 'I' n I (hereinafter referred to as 'Tanibe') is as shown in FIG. 5(a).

Furthermore, by pulling the main lever 5, the door can be unlocked and opened, although not specifically shown. At this time, the movable part 10 is further pushed in by the stepped part 11b of the protrusion II, and the second contact 9b of the main lever switch 9 is turned on, and the current flows from the power source [(, second contact 9b, resistor IN 4 ).

The flow to capacitor CI and ground quickly charges capacitor Ct, and the potential of the negative input terminal of the negative comparator [C1 becomes higher than the positive input terminal potential of the negative comparator [C1], and the output terminal of one comparator ICI becomes Inverts the "high" signal to "low" signal, and also the other comparator IC
The potential of the positive four-horn terminal becomes higher than the potential of the negative input terminal of IC2, and the output terminal of the other comparator IC2 is inverted from a "low" signal to a "high" signal. In addition, although it is -g, the other comparator IC2 is
Ic s inverts faster than each comparator ICI,
The connection point PI of the output terminal of 1C2 becomes "high", but since the time is very short, the charging of the capacitor C2 is 7'! f
Since f1 is small and the potential increases only slightly, the transistor 'rRI does not turn on and remains off. The potential of each part at this time is shown in Figure 5 (b) and (c).
- Since the transistor TR1 maintains the off state as shown in (d), the solenoid 15 is not driven.

Then, when the main lever 5 is returned and operated, the engaging claw 12 of the main lever 5 becomes a plunger! 3, the main lever 5 is prevented from returning any further, and the main lever 5 and the sub-member 16 can be released without being caught between the fingers. At this time, the second contact 9 of the main lever switch 9
b is turned off, the potential of each part is as shown in FIG. 5 (po), and the main lever 5 is maintained in this position. When the second contact 9b of the main lever switch 9 is turned off, the capacitor CI is gradually discharged and its potential becomes low, and after a predetermined period of time, the potential of the negative input terminal of the negative comparator ICI changes to the positive input. The potential of the comparator ICI becomes lower than that of the terminal, and the output terminal of one comparator ICI outputs a "high" signal. At this time, the other comparator IC
Although the potential is lower than that of the positive input terminal of No. 2, the potential manually applied to the negative input terminal is set sufficiently low, so the output terminal continues to output a "high" signal. Therefore, the potential at the connection point P■ between the output terminal of the negative comparison 'DICI and the output terminal of the other comparator IC2 becomes "high". The potential of each part at this time is as shown in FIG. When the potential of the connection point PI becomes "high", the capacitor C2 is charged, the potential becomes high, and the transistor 'l' RI is turned on. transistor T
When It I is turned on, the solenoid I5 is driven and the plunger 13 is pulled in against the biasing force of the spring 14. When the plunger 13 is pulled in, the main lever 5 is disengaged from the engagement pawl 12 and the main lever 5 is pushed back to its original position by the biasing force of the spring 8.

When the main lever 5 is pushed back to its original position, the first contact 9a of the main lever switch 9 is turned off and the solenoid 1 is turned off.
5 and the delay circuit 19 are cut off, and the plant gear 13 returns to its original position by the biasing force of the spring 4. At this time, the potentials of each part are as shown in FIGS. 5(g) and 5(d). That is, since the main lever 5 is held at an intermediate position until a predetermined period of time has elapsed after the main lever 5 is returned, when the main lever 5 is returned, the finger does not touch the main lever 5 and the sub member 6. It does not get caught in the middle, provides a good feeling of operation, and has excellent safety.
