Description

DETAILED DESCRIPTION OF THE INVENTION In particular, the present invention relates to a piano lever device for an automobile, which is capable of bringing a door into a fully latched state by operating a door when the door is in a fully latched state.

As for the conventional piano steering device, Automotive Engineering Complete Book 13
It is described in the volume ``Passenger car bodies'' (Sankaido edition),
When a door is lightly closed, it often does not close completely, leaving the door ajar. In such cases, the current approach is to completely close the door by opening the door and then closing it again, or by strongly pushing the door panel in the door closing direction.

However, it is troublesome to close the door again, and when pushing the door panel, when the door is ajar, the reaction force of the weather strip and other large forces trying to open the door are acting on the door. Therefore, the door panel must be pushed firmly into place, which may cause the door panel to become deformed.

The present invention has been made in view of these conventional problems, and involves forcibly rotating a latch member in a door lock device from a fully latched position to a fully latched position by operating a screwdriver. By making it possible to open the door when the door is ajar, just operate the handle.

Note that the other end of the cable (20) is connected to a release lever (49) in the door lock device (to), as described later.

Next, with reference to FIGS. 5 to 8, the structure of the door lock device (2) linked to the above-mentioned door lock device will be described.

Since most of the configuration of this door lock device (to) is publicly known, only the functions of the main components will be briefly explained, and only the parts directly related to the present invention will be explained in detail. I decided to.

The door lock device (to) is attached to the inner surface of the free end of the door on which the above-mentioned non-dle device is installed, at a lower part than the above-mentioned non-dle device, and includes a base plate 0υ and a hard synthetic resin fixed to the rear surface. It has a box-shaped main body and 0 sides.

As shown in FIGS. 7 and 8, in the middle part of the main body 0, there is a guide groove 6.1 into which a pin-shaped or flat U-shaped striker (331) is fixed to the vehicle body. Above the guide groove 04), a bifurcated latch member is pivotally mounted with an axis extending in the front-rear direction.

As shown by the imaginary line in FIG. 7, this latch member (1) has one leg (36a) that comes into contact with a stopper 0D formed at an appropriate position on the main body 02, and is completely separated from the striker (T). As shown in FIG.
6a) (half-latch position mark that barely engages between
(36a)■b) The striker 0-yong is completely engaged between them,
The striker can be rotated around the axis Q=''J between the full latch position (q) where the striker is held deep in the guide groove 04).

In addition, this latch member (T) is constantly biased in the counterclockwise direction in FIGS. .

At the bottom of the guide groove 0 in the main body 02, a shaft 0 extending in the front-rear direction is rotatably supported. A semicircular pawl member (40) is integrally formed in the middle of I.

This pawl member (40) is biased clockwise in FIGS. 7 and 8 by the old force of the screw spring (4I) shown in FIGS. 5 and 6, and the latch member (40) is normally It stops at the stop position shown by the solid line in FIGS. 7 and 8, where the tips of both legs (36a) (a6b) enter the rotation locus, and the latch member (G) is in the half-latch position (B). When the latch member (to) is in the fully latched position (Q, the latch member (to) is engaged with the leg piece (a6b) and the leg piece (36a) is engaged with the leg piece (36a) when the latch member (g) is in the fully latched position (Q). and prevent rotation in the counterclockwise direction in FIG.

However, by resisting the biasing force of the torsion spring (4υ) and rotating the pawl member (41 in the counterclockwise release direction in FIG. 7), the latch member G
3G), the restraint of the latch member (to) is released and the door can be opened freely.

As shown in FIG. 8, when the latch member (G) is in the half-latched position (131), its leg (36b)
The state in which the door is locked by the claw member (40) is the so-called half-door state.

The axis I39 of the latch member (G) passes through the main body C32 and the base plate l-C31) and
), and in front of it, 1 has an arm (43
The base of is fixed.

This arm (4) is integrally connected to the latch member (to) via the axis I3ω, and the latch member is in the open position (A).
, the latch member (7) is located in the open position facing downward and left from the axis 09, as shown by the imaginary line in Fig. 5.
When becomes the half-latch position, as shown in Figure 6,
When the latch member (2) is at the half-latched position (B) pointing downward and to the right along the axis C3ω, and the latch member (2) reaches the full-latching position (q), it points toward the right along the axis 0ω, as shown by the solid line in FIG. Full latch position (located in q).

The lower end of the above-mentioned rod θ0 is connected to the tip of the arm (4) with a shaft.

Rod 0G) and arm (mate and connecting member 04)
This means that when the connecting member Oa is in the position shown by the solid line in Fig. 2, the arm (4 is at the full latch position (q, and the connecting member θ4) is in the position shown by the imaginary line in Fig. 2. At this time, the arms (4) are connected to each other in such a manner that they can rotate between the half-latched position (i) and the open position (q).

This relationship is such that the rotation locus of the tip of arm +42 is along the axial direction of rod α0 from full latch position <cA to -flat position (6) and half latch position (B ) to the open position CAI is set to be substantially orthogonal to the axial direction of the rod (let).

In this way, the handle and the latch member (G) are connected to the connecting member (141), the rod (161), the arm (4 and the shaft C).
351 etc., the latch member (to) is moved to the full latch position (
When moving from C1 to the half-latch position or the open position (5), the handle can be forcibly pushed out from the closed position to the open position, and the latch member (g) is in the half-latch position fB). the latch member 0 by pushing the handle from the open position to the closed position.
6) can be forcibly rotated to the full latch position (Q), and the latch member (to) can be rotated to the full latch position (q
In this state, they are linked to each other in such a manner that the handle α can freely rotate independently between the closed position and the open position against the biasing force of the torsion spring 09.

Note that even if you try to move the handle α from the open position to the closed position while the latch member (to) is in the open position CAI, the arm (the tip of the 4 is connected to the rod 06)
Since the handle 02 is located at the bottom dead center with respect to the pulling direction, the handle 02 is restrained in the open position and cannot be moved to the closed position with a force of 4.

The shaft 01 of the pawl member (4Q) passes through the body 0 side and the base plate Oυ and projects forward of the base plate 1-Cl11, and an open lever (44) is fixed to the front end of the shaft 01. By rotating the lever in the releasing direction, which is the time-opening direction in FIG. 5, against the biasing force of the screw spring (11), the pawl member Gll is rotated in the releasing direction, can open the door.

In addition, on the front surface of the base plate 01), there are a known release lever (4ω, sub-lever (46) and a key lever (
47) etc. are provided.

Rotate the release lever (4) clockwise in FIG.
46a) pushes the arm part (44a) of the open lever 0(a) downward, and rotates the sublet/''-Gl[i) in the release direction to open the door.

The other end of the above-mentioned cable 01 is fixed to the right end of this release lever (49).
It hangs downward from the fastening part of 51, and is attached with an appropriate stopper (48).
With this, enter the other end of the cable conduit Q81 fixed upward to the base play 1・C (1) and enter the cable conduit (
After curving into a U-shape for 12 seconds, the handle device described above is reached.

In this way, push in the button knob a7) and press the lever G.
By rotating 2fil counterclockwise in FIG. 3 and pulling the cable, the release lever (451) can be rotated clockwise in FIG. 5 to open the door.

The key lever (47) is in the locked position shown in Figs. 5 and 6, and in the unlocked position slightly rotated counterclockwise in Fig. 5 about its pivot (=s7a) from this locked position. (not shown) When the sub-lever (4G) is in the unlocked position in the 5J state, the sub-lever (4G) is moved to a position where the protruding piece (46, a) can collide with the arm (44a) of the open lever. (Keep the release lever (] 5) as described above.
1, the open lever 04 is rotated in the release direction to maintain the state in which the door can be opened. As shown in Figure 6, the protrusion (46a) of the lever +461 is connected to the arm (44a) of the open lever (A4).
Move the sub-lever (40) away from the right side, rotate the release lever (45) clockwise in Fig. 5, and rotate the open lever (44) in the release direction even if you press down the sub-lever (463). It has the function of making it impossible to move the lever, thereby disabling the release action using the release lever.

The lower ends of the above-mentioned rondos (24) are connected to the right end of the four key levers (4 in FIGS. 5 and 6), and the key lever (4η) on the door locking device (7) side is and the key lever Q on the handle device side mentioned above.
υ are connected so that they interlock with each other.

By inserting a key (not shown) into the key cylinder aυ and rotating the key lever C2D in the desired direction together with the rotor therein, the key lever (4η) can be moved to the locked or unlocked position. By switching, the door lock device (to) can be placed in a locked state or an unlocked state.

Next, the operation and handling of the above embodiment will be explained.

When the door is completely closed, the latch member (To) is engaged with the striker (T) and is in the full latch position (C).
), and at this time the handle (l is in the closed position).

It is also assumed that the key lever CD is in the locked position in this state.

To open the door from outside the vehicle from this state, insert the key into the key cylinder θ (toward) provided on the bushing knob 07), and by operating this key, move the key lever (47) to the unlocked position. Move the door lock device (to) to the unlocked state.

Next, with the key removed or with the key still inserted into the key cylinder outlet, push the bushing knob Uη to the push-in position.

Then, the protrusion Yoshi and the lever (A) are rotated counterclockwise in FIG. 3, the cable is pulled, and the release lever 0ω is rotated clockwise in FIG. ,
The open lever 04 and the pawl member' (4 (j) are rotated in the release direction, and the restraint of the latch member C is released.
The door opens.

When the door is opened, the latch member (1) rotates from the full latch position (q) through the half latch position (131) to the open position (A)t, and leaves the striker 03.

Along with this rotation of the latch member (to), the arm (4) also moves from the full latch position (Q) to the half latch position (
Bl, the rod 06) is rotated to the open position (5), and the rod 06) is pulled downward, and the connecting member Oa is moved to the second
Rotate to the position shown by the imaginary line in the figure, push the handle arm (8) forward with the bent piece (14c), and then
move it to the open position.

Therefore, when the door is open, the handle θ2 always protrudes to the open position, making it easy to grasp the handle Ql+ and convenient for moving the door.

To close the door from the open state, as before, press the handle 0.
Just grab 1) and close the door.

In this case, when the door is immediately completely closed, the latch member (G) and the arm (1) are both in the full latch position (q (C)), and the rod θe is pushed up and the connecting member I is returned to the position shown by the solid line in FIG. 2, and by the force of the screw spring Q51, one of the nondles (one of them) is returned to the closed position.

Therefore, you can confirm that the door is completely closed simply by seeing the handle return to the closed position.

Also, when the door stops in the ajar state, the latch member (to) and the arm (of course) - the flutter position (Bl
(g); and υ, at this time, the connecting member Q41 remains in the position shown by the imaginary line in FIG. 2, and the nondle 0'IJ becomes the knuckle in the open position.

Therefore, even when the door is closed, by confirming that the door bolt (121) remains in the open position, it is possible to immediately know that the door is in the ajar state.

If it is desired to completely close the door from this state, the handle aυ may be pushed into the recess (3) to bring the nondle 02 to the closed position.

This toki is attached to the handle arm (8), and the bent piece (14
c) is pushed clockwise in FIG. 2, and the connecting member 0
4) is rotated in the same direction, the rod (10) is pulled upward, and the arm (2) is rotated toward the fully latched position (q).

As a result, the latch member (1) is also forcibly rotated toward the full latch position (q) while being engaged with the striker 0th floor, and when the latch member (1) reaches the full latch position (q), the pawl member (
The door is completely closed by being locked by 4Q.

Therefore, you cannot close the door again as before.
without having to forcefully press the door panel (1).
You can easily completely close the door in an ajar state.

Thereafter, if necessary, insert the key into the key cylinder aQ and perform the locking operation to restore everything to its original state.

In addition, even if the door is completely closed while the hand is placed between the handle 0υ and the case (2) during the door closing operation described above, in this embodiment, the connection will not be completed. The handle 02 is connected to the member θ4) so as to be relatively movable in the direction toward the open position, and the space between them is pulled together by the screw 9 and the spring Q51.
The load placed on the grasped hand is only the biasing force of the screw spring θω, and there is almost no risk of injury.

As is clear from the above, according to the present invention, when the door is in the ajar state, simply by pushing the handle toward the closed position, the latch member of the door lock device is forcibly rotated to the fully latched position. You can easily close the door completely.

Therefore, there is no need to perform the troublesome operation of opening the door and then closing it again as in the past, and there is no risk of deforming the door panel by pressing too hard, which is useful for handling the door.

In addition, in the present invention, when the door is closed, simply checking whether the handle protrudes to the open position or not,
This is convenient because it can be easily distinguished whether the door is ajar or completely closed.

Note that, as in the above-described embodiment, when the nondle is in the closed position, the handle closes the opening of the recess formed on the outer surface of the door, and the handle is located approximately on the same plane as the outer surface of the door. By arranging them in this way, there will be no wind noise generated when the car is running, there will be no risk of damaging pedestrians or other objects outside the car, and a beautiful appearance can be achieved.
