EXAMPLE Hereinafter, an example of the present invention will be described in detail based on the drawings.

Figure 1 is a partially cutaway front view illustrating a vehicle shift lock device installed in the driver's seat of an A/T vehicle.
, FIG. 3, and FIG. 4 are diagrams showing a cross section along ■-■, a cross section along mm, and a cross section along IV-IV in FIG. 1, respectively. In these figures, the shift lever 10 is configured with a cylindrical guide 12, and the guide 2 is attached at its lower end so as to be rotatable about an axis perpendicular to the plane of the paper of FIG. It is also connected to a hydraulic control valve of the transmission via a control cable (not shown). Further, a knob 14 is fixed to the upper end of the guide 12, and a button 16 is arranged on the knob 14 so that it can be pushed in the axial direction of the guide 12. It is designed to move the day downward. The knob 14 is composed of an outer cylinder member 14a and an inner cylinder member 14b, and is integrally fixed to the upper end portion of the guide 12 by a bolt (not shown).

The rod 18 is always urged to move upward by a biasing means (not shown), and a position pin 20 is attached to the lower end of the rod 18 in parallel to the rotation axis of the shift lever 10.

The position pin 20 protrudes from an axially long elongate portion formed on the guide l2, and is inserted into an opening 24 of a detent plate 1/22 fixed to the vehicle body.

A cam surface 26 having a predetermined shape is provided at the top of the opening 24.
is formed, and the shift position of the shift lever 10 is defined by forcing the rod 18 upward and engaging the position pin 20 with its cam surface 26. Specifically, in Fig. 1, from the left side, there are the parking position, reverse position, and neutral position. A total of six shift positions are defined: drive position, second position, and low position. Figure 1 shows the shift lever 10.
is held in the parking position.

For certain shift selection operations, such as when rotating the shift lever 10 from the parking position shown in FIG. The shift lever 10 is rotated to a desired shift position on the condition that the engagement with the cam surface 26 of the plate 22 is released.

As a result, the hydraulic control valve connected to the shift lever 10 via the control cable is switched in accordance with the shift position of the shift lever 10, and the speed change state of the transmission is changed to forward, reverse, etc. The lower end position of the rod 18, which is moved downward by the button 16 so as to release the engagement between the position pin 20 and the cam surface 26, corresponds to the operating position of the rod 18.

On the other hand, a locking means 28 is provided inside the knob 14, and when a predetermined condition is not met when the shift lever 10 held at the parking position is rotated to another shift position, a locking means 28 is provided. Specifically, when the brake is not depressed, the button 16 is prevented from being depressed and the shift lever 10 cannot be rotated. The locking means 28 includes a cam member 30 screwed onto the upper end of the rod 18, a protrusion 32 provided on the inner cylinder member 14b of the knob 14, and the button 16.
It is constituted by a recess 34 and a cam groove 36 provided in the.

The cam member 30 has a disk shape, as is clear from FIGS. 5 and 6 showing a front view and a plan view thereof,
It is slidably fitted into the thin wall portion 14c of the inner cylinder member 14b that protrudes above the guide 12, and engages with the protrusion 32 provided on the inner circumferential surface of the thin wall portion 14C. A notch 38 is formed on the outer circumferential surface. As is clear from FIGS. 2 to 4, the protrusions 32 are provided in pairs at two positions symmetrical with respect to the axis of the inner circumferential surface of the thin portion 14c, parallel to the axis, Notch 3 above
8 are also formed in pairs on the outer circumferential surface of the cam member 30 at two symmetrical positions with respect to the axis and parallel to the axis. These ridges 3
2 and the notch 38, the cam member 30 is reciprocated in the axial direction together with the rod 18 while being prevented from rotating about its axis. Further, a pair of cams 40 are protruded from the upper surface of the cam member 30, and each of the cams 40 is formed with a cam surface that slopes toward the upper surface as it goes counterclockwise in FIG. ing.

The button I6 has a seventh button showing a front view and a bottom view thereof.
As is clear from FIG. 8 and FIG. 8, an outward flange 44 is provided at the intermediate portion, and
c, and is slidably fitted into the outer cylinder member 1.
The outward flange 44 is engaged with the upper end of the knob 4a, thereby preventing it from being pulled out from the knob 14. Notches 46 are formed on the outer circumferential surface of the outward flange 44 at two positions symmetrical with respect to the axis, parallel to the axis, and are engaged with the pair of protrusions 32, respectively. , the button 16 is pressed into the knob 14 while being prevented from rotating about its axis.

The recess 34 is formed on the lower surface of the outward flange 44 in a counterclockwise direction in FIG. It is located at a portion lowered from the upper end of the thin wall portion 14c by a dimension slightly larger than the dimension obtained by subtracting the depth dimension of the recess 34 from the wall thickness in the axial direction.

Therefore, in the button 16, the outward flange 44 is engaged with the upper end of the outer cylinder member 14a, and the outward flange 44 is engaged with the upper end of the outer cylinder member 14a.
The notch 46 and the recess 34 are held in a protruding position where the upper surface of the thin wall portion 14c is approximately flush with the upper end of the thin wall portion 14c.
Rotation around the axis is allowed within a certain angular range of about 15 degrees, for example.

A circular hole 48 is formed in the center of the lower end surface of the button 16, and a torsion coil spring 50 is disposed therein. Both ends of the torsion coil spring 50 are latched into a latching hole 52 provided at the bottom of the circular hole 48 and a latching hole 54 formed at the upper end surface of the cam 30, and the button 16 is In the figure, it is urged to rotate counterclockwise. As a result, the button 16 is always held in a pushed-in position where the wall surface of the notch 46 on the side opposite to the side where the recess 34 is provided engages with the protrusion 32, and is guided by the protrusion 32 and pivots. movement in the direction is allowed.

The lower end surface of the button 16 is also formed with the cam grooves 36 at two symmetrical positions with respect to the axis, corresponding to the cams 40 of the cam member 30, and the cam grooves 36 are shown in FIG. The wall surface on the clockwise side is a cam surface that slopes clockwise in FIG. 8 toward the lower end surface.

The cam groove 36 is formed at a position offset from the cam 40 by about 15 degrees clockwise in FIG. The button 16 is moved upward according to the biasing force, and the button 16 is pushed out to the protruding position while being guided by the protrusion 32, and at the same time the button 16 is pushed out to the protruding position.
As the cam 40 is pushed into the cam groove 36 as shown in the figure, the button 16 is moved in the counterclockwise direction in FIG. 4 (in FIG. (clockwise direction) about 15 degrees. As a result, the upper end of the protrusion 32 is positioned within the recess 34, and the button 16 is engaged with the upper end of the protrusion 32.
Pushing is prevented. The rotational position of the button 16 at this time is the engagement position, and FIG. 1 is a diagram showing this state. Further, the position of the rod 18 at this time is the lock position, and the cam surface 26 of the detent plate 22 is formed to allow the rod 18 to move to the lock position only in the parking position. At the shift position, the rod 18 does not move to the lock position.

In this embodiment, the cam groove 36 and the cam 4o constitute a cam mechanism of the locking means 28, and their cam surfaces are formed over an angular range of at least 15 degrees around the axis. Further, the protrusion 32 is provided on the knob 14 so as to be immovable in the direction in which the button 16 (7) is pressed, but movable relative to the button 16, and to be positioned at a predetermined engagement position with the button 16. This corresponds to an engaging member that is engaged with the button 16 by being relatively rotated to prevent the button 16 from being pressed.

On the other hand, in the vicinity of the detent plate 22, a lock release means 56 is disposed for releasing the state in which the lock means 28 prevents the button 16 from being pressed. This lock release means 56 is provided at the upper end of the detent plate 22 so as to be rotatable about an axis parallel to the rotation axis of the shift lever 1o, and the release lever 56 is engaged with the position pin 20 from above. and a connecting rod 62 connected to an elongated hole formed at the tip of the release lever 58.

When the brake of the vehicle is depressed, the solenoid 60 is supplied with an excitation current to draw in the connecting rod 62 and rotate the release lever 58 to the release position shown in FIG. 10. As a result, the position pin 20 is pressed downward, and the rod 18 is moved from the locked position to the unlocked position against the urging force of the urging means.

In the unlocked position, the cam 40 of the cam member 30 screwed onto the upper end of the rod 18 is engaged with the protrusion 32 and completely comes out of the cam groove 36 of the button 16 held in the protruding position. set in position. When the engagement between the cam 40 and the cam groove 36 is released in this way, the button 16 is rotated from the engagement position to the push-in position according to the biasing force of the torsion coil spring 50, and the button 16 is pushed in. operation becomes permissible. Further, the button 16 comes into contact with the cam member 30 at a position where it is slightly pushed in from the protruding position, in other words, at a position where the upper end of the protrusion 32 is located above the recess 34 and rotation of the button 16 is prevented. Button 16
When the cam 4 is pushed into the cam groove 36, the cam 4 is inserted into the cam groove 36.
The rod 18 is moved to the operating position without entering the zero. As a result, the position bin 20 is lowered to the position shown by the dashed line in FIG. The shift position can now be moved eight times.

Note that when the solenoid 60 is de-energized, the connecting rod 62 moves to the original position shown in FIG. 1, that is, to the locking position of the rod 18, according to the urging force of an unillustrated urging means. is returned to a position that allows for

As described above, in the vehicle shift lock device of this embodiment, if the brake is not depressed while the shift lever 10 is held at the parking position, the rod 18 will move as shown in FIG. The shift lever 10 is moved to the lock position according to the biasing force of the biasing means, and the push-in of the button 16 is mechanically prevented by the locking means 28 disposed within the knob 14, and the shift lever 10 is rotated from the parking position to another shift position. This makes it impossible to operate the device. Further, when the brake is depressed in this state, the lock release means 56 moves the rod 18 to the unlocked position as shown in FIG. 10, and the lock means 28 prevents the button 16 from being pressed. is released, and by pressing the button 16, the shift lever 10 can be moved from the parking position to another shift position.

In this embodiment, the locking means 28 disposed inside the knob 14 prevents the button 16 from being pressed, so that the shift lever 10 cannot be moved from the parking position to any other shift position. Therefore, compared to the conventional shift lock device in which a locking member for preventing movement of the position pin 20 is arranged around the detent plate 22,
The surrounding structure becomes simpler and the installation space for the vehicle becomes smaller.

In this embodiment, the protruding strip 32 as an engaging member is integrally provided in a fixed position on the thin wall portion 14'c of the knob 14, but the button 16 is disposed so that it cannot rotate around the axis. , an engaging member is disposed so as to be immovable in the axial direction of the button 16 but rotatable around the axial center, and the engaging member is rotated around the axial center of the button 16 by the cam member 30. It can also be configured to engage with the button 16 to prevent the button 16 from being pressed.

Further, although the cam mechanism only rotates the button 16 in one direction, a cylindrical cam etc. that reversibly rotates the button 16 by reciprocating the cam member 30 in the axial direction with respect to the button 16 is used. If this is adopted, the torsion coil spring 50 can be omitted. This also applies to the case where the engaging member is arranged rotatably around the axis of the button 16 as described above.

Further, in the cam mechanism, a cam groove 36 is formed in the button 16 and a cam 40 is provided in the cam member 30, but the cam groove is formed in the cam member 30 and a cam is provided in the button 16 or the engagement member. There is no harm in doing so.

Next, another embodiment of the present invention will be described. In the following embodiments, parts substantially common to those in the first embodiment are designated by the same reference numerals, and explanations thereof will be omitted.
