Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift lever lock mechanism in which a key operation and a shift lever lock are linked in a steering lock device.

[0002]

2. Description of the Related Art When a shift lever is in a parking position, a key can be turned back in a lock position direction, and when the key is turned from the lock position to another position, the shift lever is moved to a position other than the parking position. A shift lever lock mechanism of a steering lock device which can be moved is well known, and FIG. 3 shows a main part thereof. In the figure, 11
Is a locking cable connected to the shift lever, 12
Is a lock member provided at the end of the cable 11, 13 is a cam that rotates together with the key, and 14 is a slider.

A slider 14 is supported inside a housing 15 of the steering lock device with a predetermined clearance so as to be movable in the vertical direction in the figure. Pushed up. The lock member 12 is brought into the position shown in the figure when the shift lever is in the parking position in conjunction with the shift lever.
Is a lock recess 12a formed in the lock member 12.
To lock the shift lever. When the shift lever is not in the parking position, the slider 14
Cannot be pushed up, the key cannot be returned to the locked position and turned. In this way, theft and inadvertent locking operation are prevented.

[0004]

In the case of the above-described structure, it is necessary to hold a certain length of the slider 14 with a certain clearance in order to smoothly move the slider 14 up and down without tilting. In this case, the outer dimension A in the vertical direction in the drawing is increased, and the steering lock device is inevitably increased in size. The present invention has been made with the aim of reducing the size of the steering lock device by focusing on such points.

[0005]

In order to achieve the above-mentioned object, according to the present invention, a rotary locking piece is provided in place of a slider which moves up and down, and a cam which rotates together with the key when the key is rotated back. When the shift lever is in the parking position, the lock piece is engaged with a locking recess formed in the lock member when the shift lever is in the parking position. The lock piece has a base end rotatably supported in the vicinity of the lock member. The tip can be engaged with the locking recess only when the shift lever is in the parking position, and the shift lever is parked in the engaged state. If you try to operate the shift lever side to move to the other position,
The movement of the shift lever is controlled by the tip of the lock piece and the lock member.
Are arranged along the lock member in such a direction as to be prevented by engagement with the lock concave portion and to apply a compressive load in the proximal direction.

[0006]

[Action] lock piece of the pivot is Rutotomoni cost reduction can reduce the vertical dimension compared to that of the slider formula
It is possible to achieve the same function as the lock mechanism.

[0007]

Next, an embodiment shown in FIGS. 1 and 2 will be described. The figure shows the state when the shift lever is in the parking position, and FIG. 1 shows the state when the key is not in the locked position.
FIG. 2 shows when the key is in the locked position, respectively. In the drawings, 1 is a locking cable connected to a shift lever (not shown), 2 is a locking member provided at the tip of the cable 1, 2a is a locking recess formed in the locking member 2, and 3 is a key together with a key. The rotating cam 4 is a lock piece.

Reference numeral 5 denotes a housing of the steering lock device. The lock member 2 slides in the housing 5 in the left and right direction in the figure in conjunction with the operation of the shift lever, and moves to the position shown in the figure when the shift lever is in the parking position. Is coming. The lock piece 4 has a base end 4b rotatably supported by the housing 5 so that when the lock member 2 is at the position shown in the figure, the distal end 4a can be fitted into the lock recess 2a.
And is disposed adjacent to and along the lock member 2.
Have been. The cam 3 rotates together with a key (not shown), and when the key is returned to the lock position and rotated, the cam edge 3a pushes the lock piece 4 to rotate in the direction of the lock member 2 .

In the embodiment described above, when the key, that is, the cam 3, is at a position other than the lock position as shown in FIG. 1, the lock piece 4 remains down and does not fit in the lock recess 2a. Therefore, the lock member 2, that is, the shift lever can be moved to a position other than that shown. If the lock member 2 is at a position other than that shown in the figure, the lock piece 4 is
The key cannot be returned to the locked position because it cannot be rotated by hitting the lower edge. However, in the state shown in FIG. 1, when the key is returned to the locked position, the cam 3 rotates and pushes up the locking piece 4 so that the locking piece as shown in FIG. The distal end 4a of the lock 4 fits into the lock recess 2a. For this reason, the shift lever cannot be moved and is fixed at the position shown in the figure. When the key is removed at this position, the steering lock device is locked and the steering is locked.

With such a structure, the vertical dimension of the lock piece 4 can be made smaller than that of the slider type shown in FIG. 3, and the external dimension of the housing 5 in the vertical direction also becomes smaller. Therefore, the steering lock device is downsized.

In the conventional example shown in FIG. 3, since the stress applied to the slider 14 in the locked state is a shearing load, the slider 14 must be made of a strong material such as a metal die-cast product. In contrast, this invention
Then, when the lock piece 4 is arranged along the lock member 2,
In both cases , the shape and the position of the fulcrum are as shown in the figure, so that the stress applied to the lock piece 4 in the state of being fitted into the locking recess 2a becomes a compressive load, and the material strength is not so required. For this reason, the lock piece 4 can be made of a synthetic resin, which makes it possible to reduce the weight and cost. In addition, if the lock piece 4 is made of synthetic resin, it is possible to eliminate the generation of abnormal noise when the lock piece 4 hits the lock member 2. .

[0012]

As is apparent from the above-described embodiment, in the present invention, a rotation type lock piece which is rotated by being pushed by a cam which rotates together with a key is arranged along a lock member, and a shift lever is provided. When the key is turned back while in the parking position, the lock piece engages with the lock recess of the lock member.
In addition, the shift lever is locked. Therefore, the size in the vertical direction can be reduced as compared with the conventional example in which the slider that moves in the vertical direction is provided, and the shift lever lock mechanism that interlocks the operation of the key and the lock of the shift lever is provided. In addition, the steering lock device that prevents accidental locking operation can be downsized. Also joins the lock piece
Even if the load becomes a compressive load and becomes synthetic resin, it can withstand the load
It is easy to obtain the strength of
It is possible to further reduce the weight and cost, and to easily eliminate the generation of abnormal noise.
