Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention provides a door handle device in which an insertion opening is formed by pushing in a sub-lever so that a main lever can be operated. Regarding the improvement of

(Prior Art) As shown in FIG. 1, a sub-lever 2 biased counterclockwise by a spring 1 is pushed against the biasing force of a spring l until it reaches the position indicated by the dashed line. There is one in which the door is rotated to form an insertion slot and the main lever 3 is pulled up to release the door lock.

(Problem to be Solved by the Invention) However, in such a device, when the main lever 3 is pulled up toward the user with a finger and then returned, the sub-lever 2 is already moved by the biasing force of the spring 1.
Since the lever returns to its original position, the finger may be caught between the main lever 3 and the sub-lever 2, which is very troublesome and dangerous.

The present invention has been made in view of the above problems, and the insertion opening formed by operating the sub-lever is closed by returning to the position with the sub-lever after a predetermined period of time has elapsed since the main lever was returned. It is an object of the present invention to provide a door handle device that prevents fingers from being caught between the main lever and the lever.

(Means for Solving the Problems) In order to solve the problem No. 100, the present invention provides a door handle X-handle device in which an insertion opening is formed and a main lever can be operated by pushing in a sub-lever. The basic features include a holding member that holds the sub-lever in the pushed-in position, a release member that releases the holding of the sub-lever, and a delay means that drives the release member after a predetermined time delay in response to the return operation of the main lever. It is said that

(Function) According to the present invention, after returning the main lever, the sub-lever also returns to its original position after a predetermined period of time has elapsed, so when the main lever is returned, the sub-lever remains in the pushed position. It is easy to operate without getting your fingers pinched.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

In Figures 2 to 4, 5 is the main lever and shaft 6

．． It is connected to the base of the transistor TRI via R9. A capacitor C2 is connected between the connection point between the resistor R8 and the resistor R9 and the ground, and a resistor RI is connected between the connection point between the resistor R9 and the base of the transistor TRI and the ground.

Next, the operation of this embodiment will be explained.

First, when the sub-lever 10 is pushed in, the sub-lever 10 rotates clockwise about the shaft 11 against the biasing force of the spring 12. Then, the engagement claw 15a slides on the inclined surface 13a of the plunger 13, moves the plunger 13 against the biasing force of the spring 14, engages with the tip of the plunger I3, and pushes the sub-lever 10. An insertion opening (indicated by a dashed line in FIG. 3) into which a finger can be inserted is formed. At the same time, the sub-lever switch 16 is turned on in response.

When the sub-lever switch 16 is turned on, current flows from the power source B to the sub-lever switch 16. It flows through resistors R1, R2, and R3 to ground, and one comparator ICI becomes "high", but the other comparator IC2 becomes "low", so one comparator ICI and the other comparator IC2 The connection point pt outputs a "low" signal. That is, at this time, the sub lever switch 16° and the main lever switch 9. Capacitor C1, one comparator IC1, the other comparator IC2, and the connection point Pl between one comparator I and the other comparator IC2.

Capacitor C2, transistor 1' RI (hereinafter,
It's called each part. ) is as shown in FIG. 5(a).

Next, when you insert your finger into the insertion slot and pull and operate the main lever 5, the main lever 5 rotates clockwise around the shaft 6 and unlocks the door, although it is not specifically shown. can open the door. By pulling and operating the main lever 5, the main lever switch 9 is turned on, and the current flows from the power source B to the main lever switch 9. Resistance 4
．． Capacitor CI, flows to ground, capacitor c1

The potential of the positive input terminal of C2 becomes higher than the potential of the negative input terminal of C2, and the output terminal of the other comparison D I C2 is inverted from a "low" signal to a "high" signal. Furthermore, -
Although it is instantaneous, the other comparator IC2 is better than the one comparator I.
Reverses faster than CI, and each comparator IC1, IC
The connection point of output terminal 2 becomes "high". However, since the time is very short, the capacitor c2 is not charged much and the potential rises only slightly, so the transistor TRI does not turn on and remains off. At this time, the potential of each part is as shown in Figures 5 (C), (C), and (D), and since the transistor TRI maintains the off state, the solenoid 15 is not driven and the sublever IO is turned off. The engaging claw 10a is engaged with the plunger 13, and the sub-lever 10 remains pushed in.

Then, when the main lever 5 is returned, the main lever switch 9 is turned off. At this time, the potential of each part is the fifth
As shown in Figure (E), the sub-lever 0 remains pushed in.

When main lever switch 9 is turned off, capacitor CI
is gradually discharged and its potential becomes lower, and after a predetermined period of time has elapsed, the potential of the negative input terminal of one comparator ICI becomes lower than the potential of the positive input terminal, and the output terminal of one comparator IC+ becomes " Outputs a "high" signal. At this time, the potential of the positive input terminal of the other comparator ■C2 also becomes low, but since the potential manually applied to the negative input terminal is set low enough, the output terminal does not output a "high" signal. It continues to output. Therefore, one comparator IC

When the potential of the capacitor C2 becomes "high", the capacitor C2 is charged, the potential becomes high, and the transistor TRI is turned on. When the transistor TRI is turned on, the solenoid 15 is driven and the plunger 13 is pulled in against the biasing force of the spring 14. When the plunger 13 is retracted, the sub-lever 10 is disengaged from the engaging pawl 10a, and the sub-lever IO is pushed back to its original position by the biasing force of the spring 12. When the sub-lever IO is pushed back to its original position, the sub-lever switch I6 is turned off, the energization circuit of the solenoid 15 and the delay circuit 175 is cut off, and the plunger 13 is returned to its original position by the biasing force of the spring 14. At this time, the potentials of each part are as shown in FIGS. 5(g) and 5(d).

That is, since the sub-lever 10 is pushed in until a predetermined period of time has elapsed after the main lever 5 is returned, it is possible for a finger to be caught between the main lever 5 and the sub-lever 10 when the main lever 5 is returned. It has no rt, provides a good operating feel, and is highly safe.

In this embodiment, an electronic circuit is used as the delay means, but a mechanical delay means may be provided.

(Effects of the Invention) As is clear from the above description, according to the present invention, the sub-lever is pushed in to form a finger insertion opening, the main lever is operated to release the door, and then the main lever is returned to its original position. When it is returned to its position, the sub-lever remains pushed in, so your fingers will not get caught between the main lever and the sub-lever, providing a good operating feel and excellent safety. have.
