Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention indicates the gear position on a display in a vehicle meter, for example, in conjunction with the reciprocating movement of a lever for gear operation. This invention relates to a gear position display device.

(Prior art) Conventionally, this type of display device was developed in U.S. Pat.
As shown in Figures 6 and 7, the structure consists of a character string 1 that indicates the gear position and a sliding groove that is placed parallel to this character string 1, as shown in Figures 6 and 7. 2, a pointer 4 for indicating one character in the character string 1 is movably provided in the sliding groove 2, and is fixed to the display section 3 at one end of the pointer 4. An elastic device 5 such as a spring is connected, one end of a flexible cable 6 is connected to the other end, and a fixture 7 fixed to the other end of the cable 6 is moved back and forth by a lever 8 for gear operation. The cable 6 is connected to a drum 9 that rotates in conjunction with the drum 9, and by switching and moving the position of the lever 8, the drum 9 rotates and the cable 6 is pushed and pulled, and the pointer 4 is moved into the sliding groove. 2, and the pointer 4 indicates one character in a character string 1 representing the gear position, thereby displaying the gear position at that time. Such a display device is
This is effective for vehicles that use a column shift, for example, where it is difficult for the driver to confirm the position of the lever 8.

(Problem to be solved by the invention) In this type of display device, the cable 6 is pushed or pulled in conjunction with the reciprocating movement of the lever 8, and the pointer 4 is moved into the sliding groove 2 by the amount of this pushing or pulling movement. In order to move along the drum 9, the cable 6 itself must be stretched between the drum 9 and the pointer 4. However, in such assembly work, the pointer 4 is visually aligned with the arbitrary position of the character string 1 by the worker, and then the cable 6 is fixed to the drum 9, so that variations may occur depending on each worker. Not only does this occur, but it is also difficult to tension the cable so that there is no slack.If the cable 6 is tensioned uniformly, for example, the pointer 4 may read "P" even though the gear position is "P (parking)". Since the pointer 4 may not accurately indicate one character in the character string 1, such as pointing between "R (reverse)", repeat it many times until the indicated position of the pointer 4 is correct. There is a problem in that adjustment work must be performed, and workability is extremely low.

The present invention was developed based on the above-mentioned problem, and aims to provide a gear position display device that can easily adjust the connection of connection members such as cables and accurately display the gear position. be.

[Structure of the idea]

(Means for Solving the Problems) The present invention includes a display section having a character string indicating the gear position, an indicating section having a pointer indicating one character in the character string, and a gear operation. a connecting member that moves along the character string by a push/pull operation in conjunction with a switching operation of a lever, the connecting member is connected to an indicator, and the pointer is moved in accordance with the amount of movement of the connecting member. In a gear position display device that is moved to indicate a gear position, the display section is provided with a locking section that limits the movement range of the indicating section corresponding to both ends of the character string, and the base side of the pointer is provided with a locking section that limits the movement range of the indicating section. A mounting portion for connecting the connecting member is provided, and the connecting member is allowed to slide between the mounting portion and the connecting member when the locking portion and the indicating portion are engaged, and the locking portion and the indicating portion are engaged with each other. A friction member is provided that prevents the connecting member from sliding except when the connection member is in contact.

(Function) During adjustment, set the lever to the position where the connecting member moves to the maximum or minimum, position the indicator part in the middle of the character string, and then put the lever to the position where the connecting member moves to the minimum or maximum. As a result, the connecting member is pushed or pulled by the maximum amount, and the indicating part is locked with the engaging part at the end of the character string, and a force exceeding a predetermined level is applied, so that the indicating part can move relative to the connecting member, and the gear The pointer indicates one character in the string corresponding to the position.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings. In FIGS. 1 to 3, reference numeral 11 denotes a column shift type lever, for example, for operating gears. 12 is arranged in a place where the driver can easily see it, such as inside a meter (not shown) in the vehicle, and the lever 11
This is a display section that displays the gear position in conjunction with the gear position. This display section 12 is formed of a box with an open top surface,
For example, the letters "P", "R", "N (neutral)", "D (drive)", and "L (low)" to indicate the gear position of an automatic car are displayed in a horizontal line. A dial plate 14 having a character string 13 is disposed on its upper surface, and sliding grooves 15 are formed in parallel with the dial plate 14. 16 shows the inside of the display section 12 as the dial 14
It is an indicating part that is movably received along the dial, and has a pointer 17 on the upper part that is led out from the sliding groove 15 to the upper surface of the dial 14 to indicate one character in the character string 13 on the dial 14; It consists of a holder 18 and a receiving plate 19, which are formed on the base side of the pointer 17 and serve as a mounting part for sandwiching and connecting a connecting member, which will be described later. Further, this instruction section 16 is connected to the display section 12.
The movement range is restricted by the left and right side walls 20 and 21 inside the guide 12 of the display section 12.
It moves while being supported by A. Reference numeral 22 denotes a connecting member that is pushed and pulled in conjunction with the reciprocating movement of the lever 11, and is composed of a cylindrical outer cable 23 made of hard rubber and a linear inner cable 24 made of hard steel. And this connecting member 22
The outer cable 23 is fixed to a fixing member (not shown) on the lever 11 side and the display section 12, and the inner cable 24 of the connecting member 22 has one end connected to the lever 11, which rotates in conjunction with the reciprocating movement of the lever 11 side. The other end is inserted into the display section 12 so as to be movable along the dial 14, and its tip is slightly pulled out from the right side wall 21 of the display section 12 to form a free end. It is configured so that Reference numeral 25 denotes an insertion hole for the inner cable 24 formed in the receiving plate 19 along the dial 14. A rubber member 26, which is a friction member with a large coefficient of friction, is pasted on the inner surface of the insertion hole 25, and is connected to the holder 18. A rubber member 26 is placed between the receiving plate 19
By clamping the inner cable 24 with the
When a force greater than a predetermined force is applied between the rubber member 2
The inner cable 24 can slide inside the insertion hole 25 of the indicator 16 against the frictional force of the rubber member 26, and when this force is not applied, the inner cable 24 and the indicator 16 are gripped by the frictional force of the rubber member 26. It becomes fixed and becomes movable as a unit. That is, when the instruction section 16 is within the movement range within the display section 12, the instruction section 16 moves as the inner cable 24 is pushed and pulled, and the instruction section 16 becomes a locking section on the left side wall 20 or the right side wall. 21 and when the inner cable 24 is pushed or pulled further in that direction, a force greater than a predetermined force is applied between the inner cable 24 and the indicator 16, and the fixed state between the two is released and the inner cable The indicator 16 is attached to the inner cable 24 so as to slide inside the insertion hole 25 .

The adjustment by the device of the present invention configured as described above will be described in detail below. The inner cable 24 of the connecting member 22 has a maximum length when it is pulled to the left in FIG. Its length is the minimum, and when the lever 11 is moved from "P" to "L", the inner cable 24
The length of insertion is "P" and "L" of character string 13
The length between

First, the operator fixes the outer cable 23 of the connecting member 22 to a fixing member (not shown) on the lever 11 side and the display section 12, and then moves the lever 11 to the "L" position.
position, and connect one end of the inner cable 24 of the connecting member 22 to a drum (not shown) on the lever 11 side. At this time, since the inner cable 24 is a hard wire, it is stretched, and the indicator 16 attached to the other end of the inner cable 24 is
The pointer 17 is set so as to correspond to an arbitrary position on the "P" side of the character string 13, such as "N". In this state, the lever 11 side and the display section 12 side are connected by the connecting member 22, but the actual gear position and the letters indicated by the pointer 17 do not yet correspond, and adjustment is necessary. becomes. Then, when the operator puts the lever 11 into the "P" position, the inner cable 24 of the connecting member 22 is pulled to the left, and the indicator 16 that is clamping this inner cable 24 also moves inside the display section 12. move to the left. Here, the length by which the inner cable 24 is pulled to the left when the lever 11 is moved from "L" to "P" is the length between "N" and "P" of the character string 13 set in advance by the pointer 17. longer than the length between. Therefore, while the inner cable 24 is being pulled to the left, the indicator 16 is stopped against the left side wall 20 within the display section 12 and is prevented from moving further to the left. At this time, the pointer 17 indicates "P". Then, when the inner cable 24 is further pulled to the left, the inner cable 24
Since a force equal to or greater than a predetermined force is applied between the inner cable 24 and the indicator 16, the frictional force of the rubber material 26 is overcome and the fixed state between the inner cable 24 and the indicator 16 is released.
The inner cable 24 slides inside the indicator 16,
It is pulled to a designated place and stops. By this,
The adjustment is completed when the position of the lever 11 matches the character of the character string 13 pointed to by the pointer 17. After the adjustment is made in this way, by placing the lever 11 in an arbitrary position, the inner cable 24 is pushed or pulled, and the pointer 17 indicates the character of the character string 13 corresponding to that position. Note that when the lever 11 is moved from "P", where the inner cable 24 is pulled to the maximum, to another position, the inner cable 24 is pushed back to the right side.

In this way, by keeping the inner cable 24 and the indicating part 16 in a semi-fixed state so that they can be moved when a force exceeding a predetermined force is applied, connection adjustment work can be easily performed and gears can be adjusted accurately. The location can be displayed. In addition, although the adjustment shown above involves moving the lever 11 from "L" to "P", since the inner cable 24 is always stretched with a hard wire, it is necessary to move the lever 11 from "P" to "P".
Even if it is set from "L" to "L", the instruction section 16 hits the right side wall 21 of the display section 12 and is locked, so the adjustment work can be done in the same way. Therefore, even if the position of the indicator 16 shifts during use, the lever 1
1 to "P" or "L", the indicator 16 is locked to the left and right side walls 20, 21, and readjustment is automatically performed each time.

4 and 5 show a second embodiment of the present invention, in which a flexible connecting member 27 such as a string, wire, or cable is used.
One end of the connecting member 27 is connected to the lever 11 side, and the other end is connected to an elastic device 28 such as a spring fixed to the left side wall 20 of the display section 12, and is stretched by its elastic force. In addition, the connecting member 27 is inserted into an insertion hole 29 that serves as a mounting portion provided in the indicating section 16, and is fitted by a rubber material 30 that is a friction member, so that the indicating section 16 can be attached as long as a predetermined force or more is not applied.
is fixed to. In this case as well, the same adjustment work as in the previous embodiment is performed, making the adjustment simple. Further, the connecting member 27 is pulled back while being stretched by the ammunition 28.
