Description

[Detailed description of the invention] The present invention aims to solve the following problems.

(Industrial Application Field) The present invention relates to a trunk lock device used to keep a trunk lid closed across the width of a vehicle such as an automobile.

(Prior Art) A conventional trunk lock device has a latch member and a ball that can be freely engaged and detached from the latch member pivotably attached to the base plate.

The ball is equipped with a release lever for operating the ball using the locking member of the trunk. This kind of thing has the trouble of having to go near it to open the trunk.

(Problems to be Solved by the Invention) Jin's invention attempts to provide a trunk lock device that eliminates the above-mentioned conventional problems.

That is, one object of the present invention is to prevent the latch member from returning with a pawl when the latch member of the trunk body engages with the latch member due to closing the trunk lid.
To provide a trunk lock device capable of maintaining a closed state of a trunk lid.

Another object of the present invention is that when it is desired to open the trunk lid, the latch member is released from the pawl by operating the locking member, and the latch is allowed to rotate back, thereby making it possible to open the trunk lid. It is an object of the present invention to provide a trunk locking device that has the following features.

Yet another object of the present invention is to provide a trunk lock that allows the latch member to be unlatched by the pole by operating a remote control lever when the trunk lid is to be opened from a location away from the trunk. The purpose is to provide equipment.

Another object of the present invention is that when it is desired to prevent the trunk lid from being opened even if the remote control lever is operated, the purpose can be achieved by a simple operation that requires only a slight movement of the connecting piece. An object of the present invention is to provide a trunk locking device that has the following features.

Still another object of the present invention is to provide a trunk lock device having a structure in which the size of the lower portion of the lock device is small even though the remote control can be canceled as described above.

That is, in the trunk locking device of the present invention, both the first release lever for operating the pole by operating the lock member as described above and the second release lever for operating the pole by operating the remote control lever are both They extend upwards, and each has a connecting part at the top. Further, the connecting piece is also provided at an intermediate position of the first release lever. Therefore, the lower part of the locking device has a small shape that only includes the latch member and the pawl on the base plate. If the size of this part is small, the opening formed in the trunk body of the automobile, ie, the opening into which the lower part (3) is inserted to engage the striker attached to the trunk body, can be small.

As a result, the appearance of the trunk body can be improved.

The configuration of the present invention is as follows.

(Means for Solving the Problems) The present invention takes the measures as described in the claims above, and its effects are as follows.

(Operation) When the striker hits the latch member, the latch member rotates and the striker engages with the recessed portion of the latch member. In this engaged state, the pawl locks the latch member from returning nine rotations.

When the first release lever is tilted, the latch member is released from the pawl.

When the second release lever is tilted, the first
The release lever is tilted. When the linking piece is in the cancel position, movement of the second release lever is not transmitted to the first release lever.

(Example) In FIGS. 1 and 2, a concave trunk body formed in the body 11 of an automobile 10 is covered with a trunk lid that can be opened and closed. A striker 14 is attached to the trunk body, and the striker (4) of the striker 14 is covered by a trim member having an opening 16. A well-known rubber water separator 17 is attached to the main body ν. On the other hand, the locking member 19 is used for the outer panel of the trunk lid.
is attached, and a locking device 21 is attached to the inner plate. The keyhole ρ of the lock member 19 is connected to a rotation shaft n to which the operating arm U is attached, and when the key inserted into the keyhole η is rotated, the rotation shaft Z is rotated.

Next, the lock device 4 will be explained in detail based on FIGS. 3 to 1/FIG. The base plate of the locking device 21 is bent into a dogleg shape on the plain means, and the mounting plate 26a
and a support plate 26b. The mounting plate 26a uses the through hole n formed therein to attach the plate 28a and the plate 28b.
It is attached to the inner plate by. On the other hand, support plate 26b
hangs downwards and has an introduction section 4 for introducing the striker. A latch member is rotatably attached to the support plate 26b using a shaft body 31. A bottle is used as the shaft body 31, and its tip is connected to the support plate 26.
It is caulking to b. The latch member has a retaining recess for engaging the striker, and a sound deadening member is attached to the side wall of the recess wing.The sound deadening member is made of an elastic material such as rubber. A stopper formed by bending and raising a part of the support plate 26b faces the latch member.A sound deadening member is attached to the portion of the latch member that comes into contact with the stopper.

A pole is also rotatably attached to the support plate 26b using a shaft a. This port/L'36 is formed to have the same thickness as the latch member. A bottle sb is used as the shaft a, the tip of which is caulked to the support plate 26b. The first release lever (is formed integrally with the rear of the pole and extends long upward from the pole staft).

A connecting portion provided at the tip faces the operating arm of the locking member 19. A second release lever ω is provided along the port/L' 36 and the first release lever. The lower end of this lever cutter is pivotally connected to the shaft body a, and the upper end is provided with a connecting portion 41. A wire holder of a flexible wire core is connected to this connecting portion 41 using a connector 47.

The flexible wire core tube 44 is fixed using a fastener 6 to a support piece C bent up from the mounting plate 26a. The other end (not shown) of the wire cape/L'41 is connected to a remote control lever located in the driver's seat of the automobile. A connecting piece group is pivotally attached to the intermediate portion of the first release lever holder using a pin 51 and a wave washer 51a. A connecting portion 52 protrudes from one side of the connecting piece, and a fitting piece 54 that selectively fits into a positioning hole 55° formed in the release lever holder protrudes from the other side. .

The connecting piece group comes with an integrally formed operation piece &. - A pushing part 57 is provided in the middle part of the release lever lead of the force cylinder 2. When the group of connecting pieces is positioned at the connecting position as shown in Figures 3 to S and Figure 5, that is, the position where the fitting piece bait fits between the positioning holes, the connecting portion 52 of the connecting piece (material)
is located at a position that blocks the forward and backward locus of the pushing portion 57. On the other hand, when the connecting piece W is placed in the cancel position shown in the first figure, that is, in a position where the fitting piece W fits into the hole 56, the connecting part 52 retreats from the forward and backward movement locus of the pushing part 57. A biasing spring whose one end is connected to the latch member and the other end to the first release lever holder biases the latch member in the counterclockwise direction (7), and the lever is connected to the latch member via the first release lever holder. The latch member is biased toward the opposite side. A stopper 59 for receiving the first release lever is made of an elastic material such as rubber, and is fitted into a bent piece (a) which is a part of the mounting plate 26a. A cover 62 covering the latch member (material) and the pole shaft is made of a synthetic resin material, and is made of a synthetic resin material.
37 to the support plate 26b. This cover 62 has washer sections 64. The washer part 63 is formed to have a thickness that is the sum of the thickness of the washer part 64 and the thickness of the second release lever chrysanthemum. As a result, the shaft 31 and the shaft a have the same length. The cover 62 also has an introduction part 65 which overlaps the introduction part in the support plate 26b.

The locking device 4 is assembled as follows.

First, attach the connecting piece to the first release lever.

Next, the first release lever cover and latch member (material) are placed on the board row, the second release lever cover is placed on top of the first release lever cover, and the cover 62 is placed on top of the first release lever cover. Then, the shaft bodies 31 and 37 are inserted from the side of the cover 62 (8) and their tips are caulked to the board I. In this case, a single type of shaft body 31,37 can be used. Next, the spring 58 and stopper 59 are attached.

Next, the operation of the lock device having the above configuration will be explained.

When the trunk lid 13 is open, the latch member and port/I/36 are in a state as shown in FIG. When the trunk 1i13 is closed from this state, the lower portion of the locking device 21 passes through the opening 16 of the trim b and enters inside thereof. As a result, the striker 14 enters the introduction device as shown in FIG.

The striker 14 that has entered the introduction device is caught in the latch member (
5, and rotate the latch member clockwise in the figure to engage the recess 32 as shown in FIG. In this state, the ball is tilted to a state shown in FIG. 5 due to the biasing force of the ball iris 58, thereby preventing the latch member from rotating back. the result,
The striker 14 can no longer be removed from the introduction device, and the trunk lid U remains closed. In addition, when the striker 14 comes into contact with the latch member as described above,
Since the contact area is equipped with a sound deadening member, generation of large impact noise can be prevented. Also, the ball part is a latch member (
When the release lever is locked as shown in Fig. S, the tilting movement of the release lever is received by the stopper 59 made of an elastic material, so even in this case, generation of large impact noise is prevented.

Next, the operation for opening the trunk lid L3 will be explained.

First, when opening the trunk lid by operating the lock member 19 with the key, the key is inserted into the keyhole ρ and the rotation shaft n is rotated. As a result, the connecting part ■ of the release lever field is pushed to the left in Fig. S due to the operation swelling.
The release lever blades tilt in the same direction. When the grain/l/36 is disengaged from the latch member (9) due to this tilting, the latch member (material) is rotated counterclockwise in FIG. The hold on the striker 14 is released. As a result, the striker 14 can be removed from the introduction portion, and as a result, the trunk ff113 can be brought into an open state. In addition, if the latch member (material) is rotated by the biasing force of the spring lock,
The rotation is stopped by a stopper via the sound deadening member. Therefore, no large impact noise is generated.

Next, a case will be explained in which the above-mentioned opening operation of the locking device 2 is remotely controlled using a lever on the driver's seat. In this case, the connecting pieces are positioned at the connecting position as shown in FIG. In this state, when you operate the lever on the driver's seat and pull the wire chrysanthemum, the second release lever
It tilts to the left in the figure. The movement is transmitted from the pushing part 57 to the connecting part 52 between the connecting pieces. For this reason, the first release lever blade is attached to the S position along with the second release lever chrysanthemum.
It tilts to the left in the figure. As a result, the latch member I is released from the ball holder as in the case described above.

Next, when the connecting pieces are in the cancel position as shown in Figure 1, the second release lever ω can be tilted in the same manner as above by operating the lever on the driver's seat. As shown by the imaginary line in Figure 1, the second release lever (11) merely tilts, and its movement is not transmitted to the first release lever. Therefore, the state in which the striker 14 is retained by the latch member can be maintained as it is, and the trunk lid 13 can be kept in the closed state.

(Effects of the Invention) As described above, the present invention has the effect of achieving the above object.
