Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a floor shift type shift lever used mainly for shift and select control of a gear transmission for a vehicle.

(Prior Art) Conventionally, this type of shift lever has been configured to be extendable and retractable in its axial direction as necessary. For example, in Japanese Utility Model Application Publication No. 52-84128, a shift lever is divided into a cylindrical first lever having a knob and a rod-shaped second lever partially inserted into the first lever. A shift lever is extended and contracted by sliding one lever relative to a second lever in the axial direction, and the first and second levers are fixed when the shift lever is extended. ing.

Further, other configurations of the telescoping shift lever include those shown in FIGS. 4 and 5. In the shift lever shown in FIG. 4, the shift lever is divided into a rod-shaped first lever 21 having a knob 2 and a cylindrical second lever into which the first lever 21 is slidably inserted. Then, by loosening the lock nut 20 provided on the outer periphery of the second lever 22, the first lever 21 is slid with respect to the second lever 22, and by tightening the lock nut 20 again at a predetermined adjustment position, the second lever is tightened. The first lever 21 is fixed to the lever 22. The shift lever shown in FIG. 5 has a rod-shaped lever body 23 similarly equipped with a knob 2, which is slidably attached to a cylindrical support 24.
The lock ball 25 is configured to regulate the position of the shift lever when the shift lever is in its most extended state as shown by a solid line or in its most retracted state as shown in a phantom line.

(Problems to be Solved by the Invention) In the telescoping shift lever shown in FIG. Since it is necessary to perform the same operation as tightening the lock nut 20 again, the operation becomes complicated and takes time. Also,
If the tightening force of the lock nut 20 is insufficient, the first lever 21 may be pushed downward against the driver's will during the shift and select operation of the shift lever main body.

On the other hand, although the telescoping shift lever shown in Fig. 5 is easier to extend and retract than the structure shown in Fig. 4, due to the axial operating force of the shift lever during shift and select operation,
There remains a possibility that the lever body 23 will overcome the position regulating force of the lock ball 25 and be pushed downward as in the case of the shift lever shown in FIG. In both of the telescoping shift levers shown in FIGS. 4 and 5, the first lever 21 or the lever body 3 can freely rotate around the respective axes with respect to the second lever 22 or the support body 24. Therefore, after the above-mentioned telescoping operation, the knob 2
For example, the shift pattern displayed on the top surface of the knob 2 may be reversed when viewed from the driver.

(Means for solving the problems) In order to solve the above problems, the present invention is configured as follows. As shown in FIG. 1, the shift lever of the present invention includes a lever body 1 equipped with a knob 2 at the upper end, and a cylindrical shape with an open top and bottom. It is divided into a support body 4 which is slidably inserted into the body. Inside this support body 4, there is an annular fixed body 7 fixed thereto, and a predetermined spring 16 is provided on the upper surface side of this fixed body 7, and a biasing force is always applied to the fixed body 7 side. The annular movable body 12 that received the received information is respectively incorporated. The movable body 12 is attached to the lever main body 1 such that it can rotate around the axis of the lever body 1 and be slidable in the vertical direction, and is movable with the fixed body 7. body 1
Concave and convex portions 14 and 10 that engage with each other and determine the rotational positions of the lever body 1 and the movable body 12 with respect to the support body 4 are formed on the surface facing the lever body 2 . Moreover, the lever body 1 has these uneven parts 1.
4 and 10 are held between the fixed body 7 and the movable body 12, and these uneven parts 14 and 10
A locking member 3 is provided that can pass through a groove 11 provided in the center hole 8 of the fixed body 7 when the movable body 12 is rotated by operating the lever body 1 so that the movable body 12 is in a disengaged state. .

(Function) In the above configuration, in order to shorten the length of the shift lever, the lever body 1 is pulled upward with respect to the support body 4, and the above movable lever body 1 is moved through the locking member 3 of the lever body 1. The body 12 is also pulled up against the elasticity of the spring 16. In this state, by rotating the lever body 1 together with the movable body 12 about its axis, the concave and convex portions 14 and 10 of the movable body 12 and the fixed body 7 are brought out of engagement. In this state, move the lever body 1 to the support 4.
By pushing the lever body 1 downward, the locking member 3 of the lever body 1 passes through the groove 11 provided in the center hole 8 of the fixed body 7, and the shift lever is brought into a shortened state.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

First, in Fig. 1, which shows an exploded perspective view of the components of the shift lever, and Fig. 2, which shows their assembled state, the shift lever has a knob 2 at its upper end.
The lever body is divided into a rod-shaped lever body with a cylindrical shape and a cylindrical support body 4 that is open on both the upper and lower surfaces. As is clear from FIG. 2, the support body 4 is fixed to a bracket 6, and this bracket 6 supports the shift lever so that it can be operated to shift and select, and also transmits the shift and select operation to a gear transmission (not shown). It is configured so that it can be done.

As is clear from FIG. 3A, which is a partially enlarged view of FIG. The rotation of the support body 4 is prevented by fitting the positioning protrusion 9 into the non-circular positioning hole 5 which is an open portion on the lower surface of the support body 4 . A movable body 12 similarly formed in an annular shape is incorporated into the upper surface side of this fixed body 7, and a movable body 1
A spring 16 and an annular spring seat are respectively incorporated into the upper surface of the spring 2 . Then, the spring seat is formed upwardly from the support 4 by bending (crimping) the periphery of the upper open part of the support 4 from the state shown in FIG. 1 to the state shown in FIGS. 2 and 3A. It is fixed so that it does not fly out. With the spring seat 17 positioned in this manner, the movable body 12 is always subjected to an urging force in the direction of being pressed toward the fixed body 7 due to the elasticity of the spring 16.

Further, an engagement protrusion 10 is formed on the upper surface of the fixed body 7, while a first engagement recess 1 that can engage with the engagement protrusion 10 of the fixed body 7 is formed on the lower surface of the movable body 12.
4 and a second engaging recess 15 are formed, respectively. The first engagement recess 14 and the second engagement recess 15 are formed on the lower surface of the movable body 12 at positions displaced by a predetermined angle in the circumferential direction thereof.
Further, both the recesses 14 and 15 communicate with each other through a guide groove 20 formed shallower than these. Note that the first engagement recess 14 is formed deeper than the protrusion of the engagement protrusion 10 of the fixed body 7, and the free space between the bottom surface of the recess 14 and the top surface of the protrusion 10 is used for locking, which will be described later. This is where the member 3 is located.

The lever main body 1 is inserted from a center hole 18 of the spring seat 17 incorporated into the support body 4 to a center hole 13 of the movable body 12.
The lever body 1 has a non-circular (for example, oval) cross-sectional shape, and the spring seat 17
The center hole 18 of the movable body 12 and the center hole 13 of the movable body 12 are both formed in a non-circular shape corresponding to the cross-sectional shape of the lever body. Therefore, this lever body 1
are inserted into the movable body 12 and the spring seat 17, which are incorporated inside the support body 4, so that they can both rotate around their axes and can be slid relative to each other in the vertical direction. be. When looking at this in terms of the relationship between the lever body 1 and the support body 4, the lever body 1 can rotate together with the movable body 12 and the spring seat 17 with respect to the support body 4 about its axis, and in the vertical direction. This means that only the lever body 1 can be slid.

A locking member 3 using a pin, for example, is fixed to a location near the lower end of the lever body 4, and this locking member 3 is located within the first engagement recess 14 of the movable body 12. There is. Therefore, when the lever body 1 is slid upward with respect to the support 4, the movable body 12 is also pulled upward through the locking member 3 against the elasticity of the spring 16. Furthermore, the locking member 3 is connected to the movable body 12.
the first engagement recess 14 and the fixed body 7 that engages therewith.
The above-mentioned spring 1
Since the lever body 1 is held in place based on the elasticity of the lever body 6, the lever body 1 is in a state where vibration is suppressed relative to the support body 4, and its position is restricted so that it cannot slide downward.

On the other hand, the inner diameter of the center hole 8 in the fixed body 7 is set to a size that allows the lever body 1 to be inserted therethrough, but is dimensioned so that the locking member 3 of the lever body 1 cannot pass therethrough. However, this center hole 8
A groove 11 sufficient to allow the locking member 3 to pass through is formed in a part of the lever body 1, and when the lever body 1 is rotated and the locking member 3 is aligned with the groove 11, The length of the shift lever can be shortened by sliding (pushing) the lever body 1 downward relative to the support 4. The groove 11 of this fixed body 7 rotates the movable body 12 together with the lever body 1, and the second groove of this movable body 12
When the engagement recess 15 is engaged with the engagement protrusion 10 of the fixed body 7, it is set so as to coincide with the locking member 3 described above.

Note that when assembling the lever body 1 to the support body 4, the spring seat 17, the spring 16 and the movable body 12 are attached to the lever body 1 in advance.
After respectively assembling and fixing the locking member 3 to the lever body 1, these are assembled into the support body 4 as a collective component, and the periphery of the upper open part of the support body 4 is fixed as described above. It is formed by bending.

In the shift lever configured as above,
As shown in FIG. 2, when the lever body 1 is fully extended with respect to the support 4 (the knob 2 is at the highest position), the locking member 3 fixed to the lever body 1 is As shown in FIGS. 2 and 3A, an action is applied to the movable body 12 between the engagement protrusion 10 of the fixed body 7 and the first engagement recess 14 of the movable body 12 that engages with it. It is strongly clamped based on the elasticity of the spring 16. Therefore, the lever body 1 is held in a state in which rotation around its axis is prevented from rotating with respect to the support body 4 through the fixed body 7 fixed thereto and the movable body 12 engaged therewith. At the same time, the locking member 3 comes into contact with the upper surface of the engagement convex portion 10 of the fixed body 7 to restrict the lever body 1 from sliding downward as described above. In this way, the locking member 3 of the lever main body 1 is strongly held between the engagement protrusion 10 of the fixed body 7 and the first engagement recess 14 of the movable body 12 due to the elasticity of the spring 16. This also prevents the lever body 1 from receiving vibrations from a power plant or the like with respect to the support body 4, thereby preventing vibrations (chatter) from occurring.

Next, a description will be given of an operation for shortening the length of the shift lever in order to effectively utilize the space around the driver's seat of the vehicle. First, by pulling the lever body 1 upward relative to the support body 4, the movable body 12 is also moved from the state shown in FIG. 3A to the third position by the locking member 3 fixed to the lever body. As shown in Figure B, it is pulled up against the elasticity of the spring 16. As a result, the engagement between the first engagement recess 14 of the movable body 12 and the engagement protrusion 10 of the fixed body 7 is released. Therefore, the lever body 1 is shown in Figure 3B.
If you rotate it around its axis from the state shown in
The movable body 12 rotates together with the lever body 1 to the state shown in FIG. 3C while the guide groove 20 remains engaged with the engagement protrusion 10 of the fixed body 7. The rotation of the movable body 12 at this time is determined by the engagement of the second engagement recess 15 with the engagement protrusion 10 of the fixed body 7, and in this state, the first engagement of the movable body 12 The locking member 3 of the lever body located in the recess 14 corresponds to the aforementioned groove 11 formed in the central hole 8 of the fixed body 7. Therefore, by pushing the lever body 1 downward into the support body 4 as shown in FIG. 3D, the lever body 1 passes through the center hole 8 of the fixed body 7 and slides downward, and the shift lever You can perform shortening operations.

In order to extend the shift lever that has been shortened as described above again to the state shown in FIG. 2, the lever body 1 is pulled up together with the movable body 12 again to the state shown in FIG. Movable body 1
2 to the original position shown in FIG. 3B.
In this state, the pulling force of the lever body 1 is released and the first engagement recess 14 of the movable body 12 is again engaged with the engagement protrusion 10 of the fixed body 7 as shown in FIG. 3A. When the shift lever is extended again from the shortened state as shown in FIG. , the lever main body 1 can be accurately returned to its original rotational position with respect to the support body 4. As a result, it is possible to avoid a situation where the direction of the knob 2 of the lever body 1 changes.

Note that when the lever body 1 is pulled up as shown in FIG. 3B or 3C with respect to the support body 4 as described above, the stopper function for regulating the lifting stroke is as shown in this embodiment. In this case, the close contact height of the spring 16 interposed between the movable body 12 and the spring seat 17 may be utilized, or alternatively, a stopper collar or the like may be installed between the movable body 12 and the spring seat 17. This may also be done by incorporating separate parts. Also,
As shown in FIG. 2 and FIG. and the first engagement recess 1 of the movable body 12
4, the locking member 3 may be held between the movable body 12 and the fixed body 7 at a location other than these. However, in this case as well, as shown in FIG.
0, it is essential that the locking member 3 of the lever body 1 be positioned so as to correspond to the groove 11 formed in the center hole 8 of the fixed body 7.

(Effects of the invention) As described above, the present invention allows the shift lever to be extended and retracted using operating force that is not used for the original shift and select operation of the shift lever, that is, by pulling up the lever body and rotating the lever body around its axis. This makes the operation extremely easy, and also prevents the lever body from sliding downward against the driver's will during normal shift and select operations, preventing the shift lever from being accidentally moved. By shortening the length, the above inconvenience can be avoided. Moreover, in the present invention, uneven parts that can be engaged with each other are formed on opposing surfaces of the fixed body fixed inside the support body and the movable body that is operated together with the lever body, and these uneven parts can be engaged with each other. Since the rotational position of the lever body around the axis relative to the support body is regulated in the extended state, for example, when the shift lever is extended from the shortened state to the original state, the shift lever is accurately returned to its original position in the rotational direction. For example, if the position of the knob fixed to the upper end of the lever body is always maintained in the normal orientation, and the shift pattern displayed on the top surface of this knob is reversed from the driver's perspective, You can prevent such inconveniences. In addition, when the shift lever is extended for normal operation, the locking member of the lever body is strongly held between the fixed body and the movable body that is receiving the pressing force of the spring, so that the power plant It is possible to prevent a situation where the shift lever vibrates due to vibration from etc.
