Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a luggage door lock device, and more particularly to a luggage door lock device with a built-in cancel mechanism.

Conventional luggage door lock devices (e.g.
56-149766), a base is attached to the inside of the trunk lid, and on this base,
A hook that can be engaged with a striker provided in the trunk and a pole that locks the hook are pivotally supported, and a lock lever connected to an opener cable is engaged with the pole.

Therefore, by pulling the opener cable, the pole is rotated via the lock lever, the pole and the hook are separated, and the locked state between the hook and the striker is released. Alternatively, the pole is rotated by the master key, and the lock between the hook and the striker is released.

However, in order to perform a cancel operation, that is, an operation that prevents the hook and striker from being unlocked even by the unlocking action of the opener cable, the lock lever must be directly operated to release the engagement with the pole. First, there is a problem in that the cancel operation cannot be performed when the trunk compartment is closed.

In addition, in conventional luggage door lock devices (for example, the device published in Japanese Utility Model Application Publication No. 55-35144), a hook and a pole connected to an opener cable are pivotally supported on a base, and can be rotated by operating a master key. However, a cancel lever is provided which engages with the hook to ensure the cancel state.

However, when the opener cable is activated in the cancel state, the pole rotates in the unlocking direction and the hook and pole separate.
A problem arises in that the lock strength under the cancel state is reduced.

This invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a luggage door lock device that can perform a cancel operation with the trunk closed and can improve the locking strength even in the cancel state. With the goal.

In order to achieve the above object, the luggage door lock device according to the invention includes a base provided on one of the vehicle body or the movable part, and a striker that is pivotally supported by the base and provided on the other of the vehicle body or the movable part. A hook that engages with the striker, a pole that is biased by a small spring provided between the hook and whose lower end is pivoted on a base to maintain engagement between the hook and the striker, and a pole that is activated by operating a master key when the lock is released. A drive piece that comes into contact with the open lever and a contact member that comes into contact with the opener cable when operated are provided at the upper end of the open lever, and a contact member that comes into contact with the open lever is provided between the open lever and the base and normally urges the open lever to engage with the pole. a small ellipse whose respective ends are pivotally supported by the lower end of the open lever and the base; and a hanging portion that contacts the open lever when the lock is released; The transfer lever has a small ellipse and a large ellipse facing each other via the link of the master key.The transfer lever is configured to move the drive piece above the pole by operating the master key in the opposite direction when canceling. It is configured so that it is formed in a shape that is located at.

Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the luggage door lock device according to the invention in a neutral state.

A substantially U-shaped base 1 is fixed to the lid of the trunk. A notch 3 is formed in the lower part of the base 1 along the central axis of the base 1.
A striker 5 fixed to the trunk can be inserted into the interior of the vehicle.

Further, a hook 7 is rotatably supported by a pin 9 on the right side in the figure after passing through the notch 3 at the lower part of the base 1. This hook 7 has an engagement groove 11 that can be engaged with the striker 5, and a locking protrusion 13 that can be locked with a pawl 15, which will be described later.

On the left side of the base 1 through the notch 3 in the figure is a pole 1 extending vertically in the figure.
5 is provided, and the lower part of the pole 15 is supported by a pin 17 so as to be rotatable.
A small spring 19 is interposed between the approximately central portion of the pole 15 in the longitudinal direction and the upper end of the hook 7.
As the pawl 15 rotates counterclockwise, the hook 7 is rotated in the same direction by the biasing force thereof, and the engagement between the engagement groove 11 and the striker 5 can be released.

Further, a locking portion 21 is formed above the pin 17 at the bottom of the pawl 15, and locks the aforementioned locking protrusion 13 to prevent the hook 7 from rotating counterclockwise. Furthermore, a stopper 23 is formed on the upper part of the pole 15 on the right side in the drawing, and is bent toward the front in a direction perpendicular to the plane of the paper in the drawing.

Further, a transfer lever 25 is disposed at the upper part of the base 1 along its central axis.
This transfer lever 25 has a large and small oval 25
A and 25B are in a parallel state and are integrated by a connecting portion 25C, forming a U-shaped side surface. Moreover, this transfer lever 25 is
It is rotatably supported by the base 1 by a pin 27 provided at the end of the small ellipse 25B on the side of the hanging portion 25C.

Furthermore, the tip of a link 29 is pivotally supported at the end of the large ellipse 25A on the opposite side to the hanging portion 25C, and the other end of this link 29 is connected to the key cylinder 3.
Key cylinder lever 33 that rotates around 1
is supported by Therefore, the transfer lever 25 can be rotated synchronously with the key cylinder lever 33 via the link 29 by operating the master key.

Further, at the end of the small oval 25B opposite to the pin 27, the lower end of an open lever 35 extending in the longitudinal direction of the pole 15 is rotatably supported by the pin 37. The length of the open lever 35 in the longitudinal direction is such that when the transfer lever 25 is rotated clockwise and the open lever 35 is lifted to the uppermost position.
5 is located above the tip of the pole 15, and in other cases, the open lever 3
The tip of the pole 5 is positioned below the tip of the pole 15.

The tip of this open lever 35 is a large ellipse 2
The driving piece 38 is bent toward the side 5A and extends across the pawl 15, and can come into contact with the pawl 15 when the open lever 35 rotates counterclockwise except when canceling. There is.

Further, a protrusion 39 is formed at the center position in the longitudinal direction of the open lever 35 , and a spring 41 is interposed between the protrusion 39 and the tip of the right side of the base 1 in the figure, and the spring 41 rotates the open lever 35 clockwise. is energized. Therefore, under normal conditions, the biasing force of the spring 41 causes the open lever 3 to
5 is capable of abutting and locking against the stopper portion 23 of the pawl 15.

Further, a ring-shaped contact member 43 is fixed to the upper part of the open lever 35, and the axis of this contact member 43 is perpendicular to the extending direction of the open lever 35 within the rotation plane of the open lever 35. There is.
An opener cable 47 is inserted into the interior of the abutting member 43 and has a spherical portion 45 having an outer diameter larger than the inner diameter of the abutting member 43 fixed to its tip end.

This opener cable 47 is covered by a tube 49 fixed to the left end of the base 1 in the figure, and is connected to a lever in the vehicle interior. Therefore, by pulling the opener cable 47, the contact member 43 and the ball portion 45 come into contact with each other, and the open lever 35 can be rotated counterclockwise around the pin 37.

Next, the action will be explained.

FIG. 3 is a front view showing the unlocked state using the master key in the same embodiment of the luggage door lock device according to the invention. When the master key is operated to rotate the key cylinder lever 33 counterclockwise from the neutral state shown in FIG. 1, the transfer lever 25 also rotates counterclockwise. By rotating this transfer lever 25, the connecting portion 2
5C and the open lever 35 come into contact with each other, and the open lever 35 rotates counterclockwise against the urging force of the spring 41.

Due to this rotation, the drive piece 38 and the pawl 15 come into contact with each other, and they rotate together in the same direction. By this counterclockwise rotation of the pawl 15, the locking protrusion 13 and the locking portion 21 are disengaged, the hook 7 is rotated counterclockwise, and the engagement groove 11 and the striker 5 are engaged with each other. In other words, the lock is released.

The fourth is a front view showing the unlocked state by the opener cable in the same embodiment of the luggage door lock device according to the invention. When the opener cable 47 is pulled from the neutral state, the ball portion 45 and the contact member 43 come into contact with each other. This allows Paul 15
rotates counterclockwise, the hook 7 and the pawl 15 are separated, and the lock is released.

FIG. 5 is a front view showing the canceled state of the same embodiment of the luggage door lock device according to the invention. Operate the master key from a neutral state,
Rotate the key cylinder lever 33 approximately 60 degrees clockwise. As a result, the transfer lever 25 rotates in the same direction around the pin 27, and the open lever 35 is lifted while contacting the stopper portion 23 by the biasing force of the spring 41, and the drive piece 3
8 is positioned above the pole 15.

If you pull the opener cable 47 in this state,
Although the ball portion 45 and the contact member 43 contact each other, the open lever 35 rotates counterclockwise around the pin 37 without the driving piece 38 contacting the pawl 15. Therefore, the locking protrusion 13 of the hook and the pawl 15
The locking state between the engagement groove 11 and the striker 5 is maintained in a state where the engagement with the engagement portion 21 is maintained. Therefore, the locking strength under the cancel state is improved, and the plate thicknesses of the base 1, hook 7, etc. can be reduced.

Furthermore, since the cancellation operation is performed from outside the vehicle using the master key, the cancellation operation can be performed regardless of whether the trunk is opened or closed.

Furthermore, since the lock release operation and the cancel operation are alternatively determined depending on the rotation direction of the master key, the cancel state can be canceled extremely easily by rotating the master key counterclockwise. .

Furthermore, since the open lever 35 moves in the extending direction of the pole 15 rather than in the width direction of the base 1, the width direction of the base 1 can be made smaller.
The luggage door lock device can be made smaller and lighter.

Furthermore, in the canceled state, the rotation angle of the master key is large and the keyhole is in a horizontal state, so
It is possible to easily determine from the outside whether or not the state is cancelled.

As described above, the luggage door lock device according to the present invention has the effect that a cancel operation can be performed even when the trunk is closed, and that the lock strength can be improved in this cancel state.
