This device is designed to prevent unauthorized pressing by a wire or the like inserted through a gap in the door in order to illegally release the locked state of the door.

(Example) Next, a first example of the present invention will be described with reference to FIGS. 1 to 4.

In the door locking knob N, which is assembled to lock and unlock the door of an automobile and is disposed inside the window glass G and in front of the center pillar P, the door panel 7
The bezel 4 fixed to has a rectangular bottom plate 4a,
A rectangular outer plate 4b erected at the outer end of the bottom plate 4a
and both side plates 4 arranged in parallel on both side ends of the bottom plate 4a.
c, 4c, and a flange 4 provided in an overhanging manner along each edge of the bottom plate 4a, outer plate 4b, and both side plates 4c.
A through hole 4e having a pair of arcuate edges and a pair of linear edges is opened in the bottom plate 4a, and the back side of both ends of the lower end of the flange 4d. In order to lock the bezel 4 to the door panel 7 so that the outer panel 4b is disposed on the outside of the vehicle, a pair of left and right locking pieces 4f are formed to be elastically deformable and project toward the outside of the vehicle.

The knob case 1 is attached to the door panel 7 through the bezel 4 so as to be able to move up and down.The knob case 1 has a top piece 1a having a recessed part 8 in the upper part thereof, and is tightly fitted into the through hole 4e of the bezel 4. and the lower piece 1b slidably inserted through the lower piece 1b are formed in a step-like manner,
An insertion hole 9 having a similar shape to the through hole 4e of the bezel 4 extends vertically through the upper piece 1a and the lower piece 1b.
A supporting piece 10 having a substantially inverted L-shaped cross section and having a long hole 10a penetrating through the upper part is horizontally suspended at the upper end of the recessed part 8 of the upper piece 1a, while an insertion hole 9 is provided at the bottom of the recessed part 8. A stopper 11 inserted into the upper end of the knob case 1 is formed, and a pair of inner and outer flexible pieces 12, 12, which are elastically deformable and formed parallel to each other near the lower end of the knob case 1, are each provided with a spring receiver at the lower end thereof. Claws 12a, 12a are provided in a protruding manner.

The return spring 5 is fitted onto the lower piece 1b of the knob case 1 so as to always urge the knob case 1 downward and elastically press it against the bezel 4.
the bottom plate 4a of the knob case 1, and the spring receiving claw 12a of the knob case 1.
It is interposed between.

The inner knob 2 is inserted into the insertion hole 9 of the knob case 1 so as to be movable up and down while being prevented from rotating.
The upper end of a link 6 connected to a door lock device (not shown) is screwed to the lower part of the link 6, while the upper end of the link 6 moves upward and downward into and out of the opening 9a at the upper end of the insertion hole 9 by the vertical movement of the inner knob 2. Projection piece 2
A is formed in a protruding manner, and a claw portion 13 that protrudes toward the inside of the vehicle is formed at the upper end of this protruding piece 2a.

The knob button 3, which is attached to the upper end of the knob case 1 in order to connect the knob case 1 and the inner knob 2 so that they can move upward together or to dissociate them so that they cannot move upward together, has a cross section that is attached to the support piece 10 of the knob case 1. A mounting portion 3a having a substantially inverted L-shape, and an upper piece 1a of the knob case 1 that hangs from the inner side end of the mounting portion 3a so that it can be elastically tilted in a direction horizontally across the vehicle body and can be elastically restored. The operating section 3b aligned with the inner side end surface of the operating section 3b is connected to the operating section 3b via a slightly thin flexible section 3c so as to be able to be elastically deformed. The pressing portion 3d is formed in a concave shape, and
At the lower end of the operating part 3b, a latch claw 14, which is always spaced apart and opposed to the claw part 13 of the inner knob 2, protrudes toward the outside of the vehicle, and is engaged when the knob button 3 is deformed by pressing the operating part 3b. The claw 14 engages with the claw portion 13 of the inner knob 2 to link the knob case 1 and the inner knob 2, and when the operating portion 3b is released to restore the knob button 3, the latch claw 14 engages with the claw portion 13. After disengaging from the engaged state, the knob case 1
The connection with Innanobu 2 is canceled. and,
When the inner knob 2 moves downward and the door is locked, when the operating part 3b is pressed to operate the knob case 1 upward, the latch claw 14 engages with the claw part 13 and the inner knob 2 is pulled up together with the knob case 1. On the other hand, when the operating part 3b is released and held in the restored state and the knob case 1 is operated upward, the latch claw 14 moves upward in a missed state and the knob case 1 moves upward leaving the inner knob 2 behind, causing the door to open. Unlocking becomes impossible.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, a knob button 3 attached to the upper end of the knob case 1 is formed on the upper end of the inner knob 2 in order to connect the knob case 1 and the inner knob 2 so that they can move upwardly or to dissociate them so that they cannot move upwardly. The operating portion 3b is provided with a protruding latch pawl 14 for engaging and disengaging from the pawl portion 13, which is formed so that it can be elastically tilted in a direction horizontally across the vehicle body.

Therefore, even if a wire or the like is inserted into the gap K between the center pillar P and the window glass G, the direction in which the wire or the like is inserted intersects at right angles with the direction in which the knob button 3 is pressed against the operating part 3b, so that the operating part 3b
The unauthorized act of forcibly connecting the inner knob 2 and the knob button 3 by pressing the button toward the outside of the vehicle becomes impossible, and unauthorized release operations on the locked door can be reliably prevented.

Next, a second embodiment of the present invention will be described with reference to FIGS. 5 and 6. In this embodiment, the recessed portion 8A provided in the upper end of the knob case 1A has an upper edge that is connected to the inner wall 15a and the outer wall 15b. Both side walls 1 tilted downward towards the inside of the car
5c and 15c, and a locking wall 15d whose lower part is notched is formed slightly inward of the outer wall 15b, while a claw portion 13A extending laterally in the vehicle width direction is formed at the upper end of the inner knob 2A. Projection piece 2aA on the top end
is formed. Furthermore, a mounting portion 3 is formed at the outer end of the knob button 3A to be inserted between the outer wall 15b of the knob case 1A and the locking wall 15d to lock the knob button 3A to the locking wall 15d.
While the aA is hanging down, the upper end of the mounting part 3aA is formed so that it can be elastically tilted in a direction vertically across the vehicle body, and when it is tilted downward, it is inserted into the concave part 8A of the knob case 1A. The operating section 3bA is extended sideways to the inside of the vehicle so that the operating section 3bA is connected to the flexible section 3cA via the flexible section 3cA. In order to engage the claw portion 13A of the inner knob 2A when pressed, a latching claw 14A is formed which is opposed to the claw portion 13A while always being spaced apart from the claw portion 13A.

The functions and effects of the second embodiment are explained in the first embodiment.
Since it is almost the same as the embodiment, its explanation will be omitted.

(Effect of the invention) That is, in the present invention, an inner knob connected to a door lock device is fitted in a knob case that is attached to a door panel so as to be able to move up and down, and the inner knob is attached to the knob case. The knob button that is engaged to connect or dissociate the inner knob has an operating section that is equipped with a latch claw that engages and disengages the claw formed at the upper end of the inner knob, and can be elastically tilted in a direction across the vehicle body.
