Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a foldable gear shift operation lever for a vehicle.

[Prior Art] In a cab-over type truck, etc., a hood that covers the engine located under the floor protrudes between the driver's seat and the passenger seat, but the gear shift control lever is located near the side of the hood. is the most convenient for driving operation.

By the way, due to road traffic conditions or parking space, it may be dangerous or impossible for the driver to exit from the right door.
You may have to exit through the door on the left.
In such cases, the gear shift control lever may get in the way.
It is very difficult for the driver to move from the driver's seat across the hood to the passenger seat.

[Problems to be solved by the invention] Conventionally, there is a foldable gear shift operation lever disclosed in Japanese Utility Model Application Publication No. 52-49438, but this lever has a fixed lower half or base. Due to the action of the spring between the movable upper half, a stable folded state cannot be obtained unless the movable upper half is completely tilted 90 degrees, and the folding direction is determined by the fixed position of the base.

[Problems to be solved by the invention] Therefore, the purpose of the invention is to make it possible to tilt the lower half to an appropriate inclination depending on the surrounding situation of the gear change operation lever mounting part, and to adjust the direction in which it is tilted if necessary. The purpose of the present invention is to provide a gear shift operation lever that can be used.

[Means for solving the problem] For this reason, the configuration of the present invention is to divide the gear shift operating lever into a lower lever 3 and an upper lever 2, provide a cylindrical portion at the upper end of the lower lever 3, and separate the upper lever 2 from the lower lever 3. A bendable sliding member 13 is coupled to the lower end of the upper lever with a connecting pin 14, and a spring 9 is attached to the lower end of the lower lever to force the sliding member and the lower end of the upper lever to fit into the cylindrical portion of the lower lever. A detent mechanism is provided between the sliding member and the lower lever, and maintains a state in which the lower end of the upper lever comes out of the cylindrical portion between an inner wall of the cylindrical portion and a peripheral wall of the sliding member. It was established.

[Operation] When the upper lever 2 is pulled up against the force of the spring 9, when the lower end of the upper lever 2 comes out of the cylindrical portion of the lower lever 3, the detent mechanism between the sliding member 13 and the cylindrical portion The upper lever 2 is prevented from coming off excessively, and the upper lever 2 can be tilted to a desired inclination with the connection 14 as the center.

Since the sliding member is rotatable relative to the cylindrical part,
The direction in which the upper lever 2 is tilted can be selected depending on the surrounding situation.

[Embodiment of the invention] To explain the invention based on an embodiment, as shown in FIG.
, an upper lever 2 having a knob 23, and a sliding member 13 connected to the upper lever 2 with a connecting pin 14, the sliding member 13 fitting into a preferably cylindrical portion of the lower lever 3. It is becoming more and more common.

The lower lever 3 has a hemispherical portion 1 formed at its lower end.
8 is supported on the vehicle body by known means so as to be tiltable back and forth and left and right, and is connected to a control rod of a known transmission (not shown) to achieve a predetermined meshing of the gears. . As shown in FIG. 2, a groove 5 extending in the axial direction is cut into the inner peripheral surface of the cylindrical portion 7 formed at the upper end of the lower lever 3, and a detent mechanism 17, which will be described later, is engaged with the upper end of the groove 5. Preferably an annular depression 5a regulating the alignment position
is provided. A stopper 10 is projected from the bottom of the cylindrical portion 7, and a horizontal pin 8 for locking a spring 9 is fixed.

The lower end of the upper lever 2 preferably has a circular cross section and is adapted to be fitted into the aforementioned cylindrical portion 7, and a flat portion 15 is formed by removing both sides from the stepped portion 2a.

The sliding member 13 also has a circular cross section so as to fit into the cylindrical portion 7, and has the upper lever 2 at its upper end.
A split groove 4 is provided which engages the flat portion 15 of. The connecting pin 14 crosses the split groove 4 at this engaging portion.
The flat portion 15 and the sliding member 13 are rotatably connected to each other. A radially extending cylindrical portion 16 is formed on the lower end side peripheral wall of the sliding member 13, and the engaging piece 6 is housed inside the cylindrical portion 16, and is urged into engagement with the groove 5 by a spring 12.

A tension spring 9 is stretched between the lower end of the sliding member 13 and the aforementioned pin 8, and this spring 9 normally causes the sliding member 13 and the lower end of the upper lever 2 to fit into the cylindrical portion 7. are combined.

Since the present invention is configured as described above, in the case of normal driving operation, the upper lever 2 is moved to the sliding member 13.
At the same time, it is fitted into the cylindrical part 7 of the lower lever 3,
In addition, the engagement between the engagement piece 6 and the groove 5 prevents relative rotation between the two, so the lower lever 3 is free from play.
It moves in unison with the gear, and does not interfere with gear shifting operations.

When crossing the driver's seat to get out of the left door, pull up the upper lever 2 against the spring 9, as shown in FIG. It will become depressed and you will no longer be able to pull up the upper lever 2. At this point, the upper lever 2 has just come off the cylindrical portion 7, so the upper lever 2 can be tilted in a predetermined direction about the connecting pin 14. Such an operation can be easily performed with one hand, thereby creating a passage space between the driver's seat and the front passenger's seat, allowing the driver to easily move to the left-hand door.

To return the upper lever 2 to its original state, simply raise the upper lever 2 using the connecting pin 14 as a fulcrum, and the upper lever 2 will be pulled downward by the spring 9, and the lower end of the sliding member 13 will be moved to the stopper 10. The slide member 13 and the lower end of the upper lever 2 are fitted into the cylindrical portion 7, as shown in FIG. In this case, the engagement piece 6 comes off the recess 5a and moves along the groove 4.

The engagement piece 6 which is forcefully engaged with the groove 5 by the spring 12 constitutes a detent mechanism 17, and the lower lever 3
This serves to prevent the upper lever 2 from rotating relative to the upper lever 2, and to regulate the amount by which the upper lever 2 is pulled up.

The cross sections of the cylindrical portion 7, the sliding member 13, and the upper lever 2 may be rectangular or other shapes that fit together without play, instead of being circular.

[Effects of the invention] Since the invention is constructed as described above, the upper lever can be easily pushed down by pulling it up with one hand, and when it is pulled up, it is automatically fitted into the cylindrical part of the lower lever by the spring. As a result, the folding operation is very easy, and as a result, there is nothing protruding above the seat surface between the driver's seat and the passenger's seat in the driver's cab, and when the driver exits from the left door. This has the advantage of making it easier to move between seats and improving safety when getting on and off the vehicle.

In particular, the detent mechanism maintains the upper lever in a pulled-up state, and at this time no spring force acts on the upper lever, so the upper lever can be folded in a desired direction and inclination depending on the surrounding situation.
