Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is designed to release the lock on the shift position by operating the shift lever in a direction perpendicular to the shift direction against the urging force of the urging means. This invention relates to a shift lever device for an automatic transmission.

[Prior Art] Conventionally, for example, a shift lever device for an automatic transmission in an automobile has a structure shown in FIG. 4. That is, 1 is a shift pattern formed by a through hole in the locking member 2, and on the right side of this in the figure, a plurality of, in this case six, shift patterns are formed by concave locking portions each having an open left side. Positions: parking position 3, reverse position 4, neutral position 5, drive position 6, second position 7 and low position 8
are formed in a line in the vertical direction in the figure. Reference numeral 9 denotes a shift lever provided through the shift pattern 1, which is supported at its lower end so as to be rotatable in the shift direction, that is, in the vertical direction in the figure, and to be swingable in the horizontal direction in the figure, which is perpendicular to the shift direction. has been
The automatic transmission is switched in response to the movement operation in the shift direction. Further, this shift lever 9 is always biased rightward in the figure by a biasing means such as a spring, and this biasing force causes it to move to one of the shift positions of the shift pattern 1 (in the figure). It is adapted to be locked in the neutral position 5). In this shift lever device, when moving the shift lever 9 from one shift position to another, first move the shift lever 9 in the direction indicated by the arrow in the figure against the biasing force of the biasing means. Tilt it in direction A (to the left) to release the lock for one shift position,
Then, it is moved in the shift direction (vertical direction) and locked at another shift position.

However, in the above-mentioned one, the shift lever 9
When moving from one shift position to another, the direction in which the shift lever 9 is released from the shift position is the same in all shift positions (direction of arrow A).
Therefore, for example, when it is desired to operate the shift lever 9 located at the drive position 6 to the neutral position 5, there is a problem that the shift lever 9 may be moved to the reverse position 4 unnecessarily.

[Purpose of the invention] The present invention has been made in view of the above circumstances, and its purpose is to provide a shift lever device for an automatic transmission that prevents unnecessary operation of the shift lever.

[Summary of the invention] The present invention divides a plurality of shift positions of a shift pattern into a plurality of position sections, and also sets the opening direction of a locking portion that locks a shift lever of a shift position to one position that is adjacent to the other. The shift position in one area and the shift position in the other position area are in a relationship that is opposite to each other,
The unlocking direction of the shift lever for the shift position is configured to be opposite between adjacent position sections, thereby preventing the shift lever from moving from one position section to the other unexpected position section unnecessarily. It is characterized by the fact that it cannot be manipulated by others.

[Example] Below, Figures 1 and 2 are shown for the first example of the present invention.
This will be explained with reference to the figures. First, in Figure 2, 1
Reference numeral 1 denotes a support member fixed to the floor of an automobile, for example, and rotatably supports a support shaft 12. Reference numeral 13 denotes a shift lever, which is connected to the support shaft 12 by a pin 14 at its lower end, and is rotatable in the up and down direction in FIG. An automatic transmission (not shown) is switched in response to a movement operation in the shift direction. Reference numerals 15 and 16 denote first and second spring members serving as biasing means, which are wound around the support shaft 12 and positioned on the left and right sides of the shift lever 13, respectively. Spring member 15
has one end fixed to the support member 11 and the other end fixed to the left side of the shift lever 13, and constantly biases the shift lever 13 in the right direction perpendicular to the shift direction. The member 16 has one end locked to the support member 11 and the other end locked to the right side of the shift lever 13 .
is always biased in the left direction perpendicular to the shift direction, and therefore, in this case, the shift lever 13 is constantly biased in the direction shown in FIG. As shown by the dotted chain line, it is biased to be located at the intermediate position C between the left and right sides. Reference numeral 17 denotes a locking member fixed to the upper part of the support member 11, and the locking member 17 has a substantially square-shaped through hole so that the shift lever 13 passes through the locking member.
8 is formed. This shift pattern 18 has a plurality of concave locking portions, in this case six.
The first shift position is parking position 19, reverse position 20, neutral position 21, drive position 22, second position 23 and low position 24.
They are formed side by side in the vertical direction in the figure. and,
In this case, these six shift positions 19 to 24 are the parking position 19 located on the upper right side and the first position section 25 of the reverse position 20, and the neutral position 21 located on the lower left side. , drive position 2
2. It is divided into a second position section 26 of a second position 23 and a low position 24, and the locking portions of the shift positions 19 and 20 in the first position section 25 are opened on the left side, respectively.
Further, the locking portions of the shift positions 21 to 24 in the second position section 26 are open on the right side, so that the shift positions in the first position section 25 and the second shift position section are open. The opening directions of the locking portions and the shift position in 26 are opposite to each other. In this case, the right side of the locking portion at each shift position in the first position section 25 and the left side of the locking portion at each shift position in the second position section 26 are connected to the shift lever 13. It is located on the center line at an intermediate position (the position indicated by the two-dot chain line in FIG. 2). Thus, the shift lever 13 is locked to the shift position in the first position section 25 in a state where it is pressed to the right by the biasing force of the first spring member 15, and The second spring member 16 for the shift position in the second position zone 26
The shift lever 13 is locked in a state where it is biased to the left by the biasing force of the shift lever 13.
The unlocking direction for the shift position is as follows:
The shift position in the first position area 25 is to the left, while the shift position in the second position area 26 is to the right.

In the above configuration, when moving the shift lever 13 from a state where it is locked at the shift position in the first position section 25 to another shift position, first, the shift lever 13 is moved from the first shift position to the first shift position.
This is done by pushing the shift lever 13 to the left against the biasing force of the spring member 15 to release the lock on the shift position and moving it in the shift direction.
When moving the shift lever 13 from a locked state to another shift position, first push the shift lever 13 to the right against the biasing force of the second spring member 16, and then move the shift lever 13 to the right shift position. This is done by releasing the lock from the holder and moving it in the shifting direction.

In this way, according to this embodiment, the shift lever 1
Since the unlocking direction for the third shift position is opposite between the first position section 25 and the second position section 26, for example, the shift lever 13 is moved to the second position section 26.
To operate the shift lever 13 from the second position to the first position section 25, move the shift lever 13 to the right against the urging force of the second spring member 16, move it in the shift direction, and then move the shift lever 13 to the first position 25. The shift lever 13 cannot be moved to the shift position in the first position section 25 unless it is pushed to the left against the urging force of the shift lever 15 and then moved in the shift direction. Unlike when the unlocking direction is the same in all shift positions, for example, when operating from the drive position 22 in the second position section 26 to the neutral position 21,
It is possible to prevent an operational error such as unnecessarily operating the reverse position 20 or the like within the second position section 25. Furthermore, in this case, the direction in which the shift lever 1 is unlocked from the shift position is in the left direction away from the center line in the shift direction in the first position section 25;
In the second position section 26, it is in the right direction away from the center line in the shift direction, and both are in the outer direction away from the center line in the shift direction.
It is possible to more reliably prevent continuous operation between the first position section 25 and the second position section 26.

FIG. 3 shows a second embodiment of the present invention.
This embodiment differs from the first embodiment described above in the following points. That is, taking into consideration the fact that it is generally not dangerous to change from the state held in the neutral position to the parking position, reverse position, drive position, second position, or low position, the neutral position 21
, the first position section 25 and the second position section 26 of the shift pattern 18 having a substantially square shape.
It is located at the intermediate portion 18a connecting the two.

In each of the above embodiments, the direction in which the shift lever 13 is released from the shift position is set to the reverse position 20 and the neutral position 2.
1 (or drive position 22), but the present invention is not limited to this, and for example, the direction may be reversed between the second position 23 and the low position 24 as well.

[Effects of the invention] As is clear from the above description, the present invention divides a plurality of shift positions in a shift pattern into a plurality of position sections, and also divides a plurality of shift positions in a shift pattern into a plurality of position sections, and also opens a locking part that locks a shift lever at a shift position. The directions are set so that the shift positions in one position section and the shift positions in the other position section which are adjacent to each other are opposite to each other, and the directions in which the shift levers are released from locking with respect to the shift positions are set to be mutually opposite. Since the adjacent position sections are arranged in opposite directions, it is possible to prevent the shift lever from being unnecessarily operated from one position section to another position section. Furthermore, in this case, the biasing means biases the shift lever to a neutral position that is perpendicular to the shift direction and on the center line of the shift direction, and the direction of release of the shift lever from the shift position is mutually controlled. Since the direction is opposite between adjacent position sections and the direction is away from the center line of the shift direction in each position section, it is more reliable that the shift lever is operated continuously between adjacent position sections. It has the excellent effect of preventing
