Abstract

PURPOSE:To easily move a seat with no protrusion of a fallen lever part and a shift knob by folding a shift lever toward an assistant driver's seat only at a prescribed position after operation of a parking brake. CONSTITUTION:A shift lever 10 is divided into an upper lever part 20 at the side of a shift knob 21 and a lower lever part 30 at the side of a gearbox and can be folded at the joint between both parts. The cover members 70 and 90 have guide grooves 76 and 96 that allow the part 20 to be folded toward the assistant driver's seat only at a prescribed position. Furthermore, a stopper means 120 functions to prevent the part 20 from its folding state and is released when a parking brake is operated. Therefore, the part 20 is never coincident with both grooves 76 and 96 of members 70 and 90 at shift positions excepting for a prescribed position. Thus, the lever 10 is not folded. Then the part 20 is not folded either unless the parking brake is operated.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a foldable shift lever device for a vehicle transmission, and more particularly, the present invention relates to a foldable shift lever device for a vehicle transmission, and more particularly, the present invention relates to a foldable shift lever device for a vehicle transmission. This relates to a folding shift lever device.

[Conventional technology]

2. Description of the Related Art In recent years, in vehicles such as automobiles, so-called floor shift shift levers have become popular, in which the shift lever of the transmission is disposed on the vehicle floor between the driver's seat and the passenger's seat. A shift lever that stands upright from the vehicle floor inside the vehicle is used to switch gears of the transmission via a remote control link system (control cable, etc.). In automobiles equipped with this floor shift type shift lever, the driver often gets in and out of the vehicle from the passenger seat in places where parking spaces are narrow or where traffic is heavy. In this case, when moving from the driver's seat to the passenger's seat, or from the passenger's seat to the driver's seat, the shift lever, which stands upright from the vehicle floor, becomes a protrusion that gets in the way, making it difficult to shift easily. Therefore, the shift lever conventionally installed on the vehicle floor is divided into upper and lower halves, and the two are connected with a bin to make the shift lever bendable, thereby making it easier to change seats. (For example, Japanese Utility Model Publication No. 56-32887 and Japanese Utility Model Publication No. 56-42729) have been proposed.

[Problems to be solved by the invention]

However, in the conventionally proposed foldable shift lever device described above, when moving the seat, the shift lever is bent and folded in the longitudinal direction of the vehicle (in the direction of gear change operation for automatic transmissions and in the shift direction for manual transmissions). The structure is as follows. Moreover, regarding the bending operation position of the shift lever,
No measures have been taken to regulate it. Therefore, when the shift lever is bent toward the front of the vehicle and laid down, the tilted shift lever tends to get in the way, especially in cab-over type vehicles. Furthermore, when the shift lever is bent toward the rear of the vehicle and laid down, it interferes with the console box, parking brake lever, etc., making it impossible to lower the shift lever to a sufficiently low position, and the shift lever tends to get in the way. Furthermore, when the shift lever is bent, the bent portion is exposed and forms a protrusion, and clothing may be caught on the bent portion when moving the seat in the vehicle interior. Furthermore, even if a caution plate is attached that explains precautions for bending the shift lever, it is impossible to move the shift lever in the neutral position with the engine running while the vehicle is stopped.
It is conceivable that the vehicle could be folded and laid down, leaving the driver's seat in this state. It is also conceivable that a part of the user's body may accidentally touch the shift lever when moving the seat. Therefore, it is desirable to take safer measures even in such unlikely cases. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a foldable shift lever device for a vehicle transmission so that the shift lever that is folded and folded down does not get in the way when the seat is moved, and to further improve safety.

[Means to solve the problem]

Therefore, the present invention adopts the following configuration as a means for solving the above-mentioned problems. That is, the present invention provides a folding shift lever device for a vehicle transmission as described above, in which a cover member that is attached to a fixed member and covers a bent portion of the shift lever is configured to bend an upper lever portion toward a passenger seat only at a predetermined position. The present invention is characterized in that a guide groove is formed to allow the bending of the upper lever portion, and a stopper means for preventing bending of the upper lever portion is provided, and the stopper means is configured to be released when the parking brake is operated. Specifically, referring to FIGS. 1 to 4 and FIG. 16 as examples, a foldable shift lever device for a vehicle transmission includes a shift lever (
10) is the upper lever part (20) on the shift knob (21) side
and a lower lever part (30) on the transmission side, and these two lever parts (20, 30) are foldably connected by a joint means (40). A predetermined value of 1 (
A guide groove (76, 96) is formed that allows the upper lever portion (20) to be bent toward the passenger seat only in the P range. Furthermore, stopper means (120) are provided to prevent bending of the upper lever part (20). This stopper means (120) is configured to be released when the parking brake is operated.

[For use]

According to the above-mentioned means, at a shift position other than the predetermined position (P range), the upper lever part (20
) and the guide grooves (76, 96) formed in the cover member do not match, making it impossible to bend the shift lever (10). When the shift lever (10) is shifted to a predetermined position (P range), the upper lever part (20) and the guide grooves (76, 96) formed in the cover member are separated, and the shift lever (10)
) is the bendable position. However, if the parking brake is not operated, the stopper means (120) prevents the upper lever part (20) from bending. Therefore, when the parking brake is operated, the stopper means (120) is released. As a result, the upper lever part (
20) can be folded down to the passenger seat side along the guide grooves (76, 96). In other words, the shift lever (10) cannot be bent and pushed down unless the parking brake is operated. Then, with the shift lever in the tilted state, the driver's seat is moved, that is, from the driver's seat to the passenger's seat, or from the passenger's seat to the driver's seat.

That is, a pipe-shaped rotating shaft 22 is welded to the lower end of the upper lever portion 20, as shown in FIG. On the other hand, the lower lever portion 30, as shown in FIGS. 1 and 3, consists of a fork-shaped shift lever support 31 and a pipe-shaped rotating shaft 32, both of which are welded together. A bolt 41 is passed through a hole formed in the sabot 31 and fastened with a nut 42 via a spring washer. The pipe-shaped rotating shaft 22 of the upper lever portion is concentrically arranged on the outer periphery of the bolt 41 via a collar 43 and a pair of flanged bushes 44 made of resin. As a result, the upper lever portion 20 is rotatably coupled in the left-right direction (vehicle width direction) in the plane of FIG. 3 about the axis Z-Z of the pole 1-41. A torsion spring 50 is wound around the outer periphery of the pipe-shaped rotating shaft 22, and its protruding intermediate portion 51 is attached to the upper lever portion 20, and both bent end portions 50 are attached to the upper lever portion 20.
2 are respectively locked to the supports 31 of the lower lever part. The torsion spring 50 biases the upper lever portion 20 in the right direction (shift lever bending direction) in the paper of FIG. Note that a tension spring may be used instead of the torsion spring 50. Reference numeral 60 denotes a lower bracket, which is integrally fixed with a plurality of bolts and nuts to a chassis-frame cross member on the vehicle frame side (not shown) together with a cable bracket 61 fastened to the lower surface thereof with a plurality of bolts and nuts. There is. The lower bracket 60 supports the shift lever 1O rotatably in the longitudinal direction of the vehicle. That is, as shown in FIG. 3, a seat lever retainer 62 having a pair of left and right upright portions 62a is welded to the upper surface of the lower bracket 60. A shift lever is provided on the outside of the pair of upright portions 62a.
A detent plate 70 is arranged to regulate the shift position of 1O, and one bolt 6 passes through these holes.
3 is fastened with a nut 64 via a spring washer. Further, the pipe-shaped rotating shaft 32 of the lower lever part is arranged concentrically on the outer periphery of the bolt 63 located inside the pair of upright parts 62a via a collar 65 and a pair of resin flanged bushes 66. . As a result, the shift lever 10 is rotatably supported about the shaft 11x-x of the bolt 63 in the left-right direction on the paper of FIG. 1 (vehicle longitudinal direction). The shifting positions of the shift lever 10 are parking range (P range), reverse range (R range), neutral range (N range), drive range (D range), and third range (3 ranges) from the front of the vehicle.

Reference numeral 7 denotes a resin-made flanged bushing interposed between the pin shaft 67 and the lower bevel gear 34. Further, a pin 38 is fixed to the tip of the control lever 36, and the end of the control cable is fitted into the pin 38 via a rubber bush (not shown). As a result, the rotational motion of the shift lever 10 around the axis XX is converted into the rotational motion of the control lever 36 around the axis Y-Y by the pair of bevel gears 33 and 34, and the control cable is further reciprocated in the longitudinal direction of the vehicle. The automatic transmission is configured to be operated to switch the automatic transmission to a predetermined gear position. Note that the dashed dotted line C in FIGS. 1, 2, and 5 indicates the central axis of the control cable. Furthermore, as shown in FIGS. 1 and 4, the shift lever retainer 62 is integrally formed with a solenoid mounting plate 62d that is continuous with the passenger side upright portion 62a. Note that the solenoid mounting plate 62d may be formed separately in advance and fixed to a fixing member such as the lower bracket 60 or the detent plate 70. The detent plate 70 has a shape as shown in FIGS. 6 to 8, and has bolts 63 passing through holes 71 formed in a pair of side walls 70a in the vehicle width direction, and holes 70 formed in a wall 70c in front of the vehicle. The shift lever is inserted through the hole 72.
It is attached by a bolt 69 (FIG. 1) fastened to a nut 68 welded to the front upright portion 62C of the retainer. The earth wall 70b of the detent plate has a curved shape centered on the central axis (axis XX) of the pair of holes 71. As shown in FIG. 6, the upper wall 70b is formed with a step-shaped detent groove 73 extending in the direction of shift lever operation (vehicle longitudinal direction) for regulating the shift position of the shift lever 10. The upper lever portion 20 described above is pressed against the end surface 73a of the detent groove 73 on the passenger seat side by the spring force of the torsion spring 50. At the R range, N range, D range, 3 range, 2 range, and L range positions on this detent groove end surface 73a, upper lever portions 20 An arcuate groove 73 corresponding to the outer circumferential surface of the groove 73. l ・73

In this way, the N range, D range and 3 range are obtained on the same plane, and the R range and 2 range are at the position where the shift lever 10 is operated around the axis Z-Z toward the driver's seat (upper part of Fig. 2). Furthermore, P range and L
The range can be obtained by moving the shift lever 10 further toward the driver's seat. Further, the detent groove 73 in the upper lever portion 20
Each step 74F of the detent groove is in contact with the

A parallel width across flats 23 is formed for abutting against and accurately setting the shift operation position. The width W2 of the P range groove 75 in the detent groove is set to be smaller than the outer diameter D1 of the upper lever portion shown in FIG. 1, and slightly larger than the width WI between the widths across flats 23. Further, the detent plate 70 is formed with a guide groove 76 that allows the upper lever portion 20 to be bent toward the passenger seat only in the P range. That is, this guide groove 76 is formed to extend toward the passenger seat side continuously from the P range groove 75, and is substantially orthogonal to the direction of shift lever gear change operation, and its axis extending from its center line A is the axis X. It extends in the direction passing through -X. The front surface of the vehicle is made flush with the stepped portion 74F of the P range groove, and the rear surface of the vehicle is shaved so that the width W of the intermediate portion thereof is the outer diameter of the upper lever portion shown in FIG. The width W of the lower end thereof is set to be approximately the same as the width W of the P range groove. Furthermore, the side wall 70a of the detent plate on the passenger side
A locking hole 70d is formed in which a plunger of an electromagnetic solenoid, which will be described later, can fit therein. A pin 77 forming a rotating shaft of a slide stopper (described later) and a pin 78 to which one end of a return spring of the slide stopper (described later) is engaged are welded to the inner circumferential edge near the axis XX. Further, an arcuate groove 79 is formed on the outer peripheral edge thereof, into which a release knob of a slide stopper, which will be described later, is attached. The center of this arcuate groove 79 is the axis O-o of the bottle 77. Note that the axis O-0 of the bin 77, which constitutes the rotation axis of the slide stopper, is located on the axis connecting the axis XX and the center line A of the guide groove 76. As shown in FIGS. 9 to 11, the slide stopper 80 has a broken-circuit shape with an upper wall 80b bent at right angles to the outer peripheral edge of a side wall 80a. This upper wall 80b blocks the guide groove 76 and comes into contact with the upper lever portion 20. A pipe-shaped rotating shaft 81 that fits into the bin 77 is welded to its lower end. The outer peripheral surface of the upper wall 80b has a curved shape centered on the central axis (axis vAo-o) of the pipe-shaped rotating shaft 81, and is configured to slide along the inner peripheral surface of the soil wall of the detent plate 70. It has become. Further, on the side wall 80a of the slide stopper, a knob mounting shaft 8 that fits into the circular arc groove 79 of the detent plate is provided on the outer peripheral edge thereof.
A pin 83, to which one end of a return spring to be described later is locked, is press-fitted and welded parallel to the axis O-0. The front end surface (left end surface in FIG. 1O) of the slide stopper 80C is formed as an inclined surface forming an angle θ with respect to a plane B connecting the axis O-◯ and the front end surface of the upper wall 80b. Furthermore, the rear end surface 80d of the slide stopper is a locking surface (flat surface) that comes into contact with a stopper means that is interlocked with a parking brake, which will be described later. As shown in FIG. 3, this slide stopper 80 is constructed by fitting a pipe-shaped rotating shaft 81 to a bin 77 fixed to a detent plate via a pair of resin flanged bushes 84. It is rotatably supported around the axis 0-0 of 77. Furthermore, it is held in the axial direction by a snap ring 86 fitted into an annular groove of the bottle 77 via a spacer 85. Slide stopper 80
The rotation angle is regulated within a certain range of angles by the contact relationship between the knob mounting shaft 82 and the arcuate groove 79 of the detent plate. 87 is a return spring (
A torsion spring), the middle part of which is wound around a vibrator-like rotating shaft 81, and both ends of which are locked to a pin 78 of a detent plate and a pin 83 of a slide stopper, respectively. This return spring 87 is designed so that the slide stopper 80 is connected to the guide groove 76 so that the shift lever 10 does not fall down even when it is in the P range.
is biased in the direction of blocking it. That is, the slide stopper 80 is biased to the left in the paper of FIG.
1 in the position shown in FIG. In this way, the slide stopper 80 that blocks the guide groove 76 functions as a part of the detent plate 70 by preventing the shift lever 10 from bending during normal operation, and also closes the guide groove 76 to ensure sealing performance. . A plate washer 88 is fitted onto the knob mounting shaft 82 and interposed between the detent plate 70 and the slide stopper 80. Note that a tension spring can also be used as the return spring 87. In addition, FIG. 3 is partially cut away at a plane including the knob attachment shaft 82 so that the attachment relationship of the slide stopper 80 and the stopper release knob can be easily understood. The resin cover 90 has a box shape that covers the detent mechanism described above, and has a similar shape corresponding to the detent groove 73, guide groove 76, and arcuate groove 79 of the detent plate, as shown in FIGS. 12 to 14. Groove 93.
96 and 99 (FIG. 5). The upper wall 90b of the resin cover has a curved shape centered on the axis XX, similar to the detent plate 70,
A pair of parallel protrusions 91 along the curved shape are provided on the inner surface.
is formed. Both protrusions 91 are connected to the outer peripheral surface of the earthen wall of the detent plate 70 and the resin cover 9, both of which have a curved shape.
This serves as a guide for the slide cover 100 that is inserted in the gap between the slide cover 100 and the inner circumferential surface of the earthen wall. And this resin cover 90
is attached to the detent plate 70 with four screws 94 tightened into holes 92 formed in the left and right side walls 90a. Further, a stopper release knob 89 made of resin is screwed to the tip of the knob attachment shaft 82 that protrudes through the arcuate grooves 79 and 99. A plate washer 98 is fitted onto the knob mounting shaft 82 and interposed between the detent plate 70 and the resin cover 90. Note that the lower inner circumferential surface 90C of the resin cover 90 is formed as an inclined surface (draft angle during injection molding) from the viewpoint of sealability and assemblability with a rubber boot 110, which will be described later. The slide cover 100 slides integrally with the shift lever 10 along the outer circumferential surface of the earthen wall of the detent plate 70 and the inner circumferential surface of the earthen wall of the resin cover 90, and displays the gear shift position, and also displays the gear shift position in other than the P range. Cover and seal. This slide cover 100 has the shape of a flexible, ultra-thin plate made of a resin material. A cutout groove 101 is opened in the end surface on the passenger seat side (lower in the figure) shown in FIG. 15 to fit with the width across flats 23 of the upper lever part and to allow bending of the upper lever part 20. is formed. As shown in FIG. 1, the rubber boot 110 includes a base 112 in which a reinforcing metal plate 111 having an angular cross-section is embedded, and a weather strip type seal that is fitted and attached to an outer circumferential groove 113 formed in the base 112. 114. The base 112 is attached to the lower bracket 60 in advance by fastening three screws 115 shown in FIG. 2 to a nut 116 (FIG. 5) welded to the lower bracket 60. Then, the upper outer circumferential surface of the base 112 is tightly fitted into the inner circumferential surface 90c of the resin cover to seal the two. In addition, in FIGS. 1 and 5, the rubber boots 11
0 is shown in a free state, but when it is actually mounted on a vehicle, the seal portion 114 is pushed down by the vehicle floor F shown by the imaginary line in FIG. It seals the space between them. In this way, the resin cover 110 is installed between the lower bracket 60, the resin cover 90, and the vehicle floor F, and prevents water, mud, dust, etc. from entering the vehicle interior, and also blocks noise from outside the vehicle interior. Now, an electromagnetic solenoid 120 serving as a stopper means interlocked with parking brake operation is attached to the solenoid mounting plate 62d of the lower bracket with two screws, as shown in FIGS. 1 and 4. The electromagnetic solenoid 120 includes a plunger 121 and a compression coil spring 122. The plunger 121 is connected to the locking surface 8 of the slide stopper.
0d and can be fitted into the locking hole 70d of the detent plate. Further, the compression coil spring 122 is connected to the plunger 12.
1 to slide stopper 80 and detent plate 7
0 (right side in Figure 4). Thus, when the electromagnetic solenoid 120 is in the ON state, the plunger 121 is fitted into the locking hole 70d of the detent plate against the compression coil spring 122, thereby preventing the slide stopper 80 from rotating. Furthermore, the electromagnetic solenoid 120 is wired based on the electrical circuit shown in FIG. That is, the negative terminal is connected to the pantry 123 as an ignition switch (hereinafter referred to as IGSW).
) 124 and a parking brake interlocking switch (hereinafter referred to as PKB interlocking SW) 125,
The other terminal is grounded. PKB linked 5W125 is
In conjunction with the parking brake operation, the parking brake indicator lamp (hereinafter referred to as PKB) is activated when the parking brake is operated.
(referred to as an indicator lamp) is switched to the 126 side. Therefore, when the IGSW 124 is ON, the electromagnetic solenoid 120
and when the parking brake is not operated (PKB interlocking SWI
25 is turned ON (on the electromagnetic solenoid side). Also,
When IGSW124 is ON and the parking brake is operated (PKB interlock 5W125 is ON on the PKB display SW side)
, and IGSW124 are turned off when they are 0FF (7). In the foldable shift lever device for a vehicle transmission configured as described above, the shift lever 10 is operated around the axis Z-Z along the detent groove 73 of the detent plate, and also around the axis X-X. Manipulate. As a result, the control lever 36 is rotated around the axis Y-Y via the pair of bevel gears 33 and 34, and the control cable (not shown) is reciprocated in the longitudinal direction of the vehicle, thereby controlling the automatic transmission (not shown). Operate the manual valve lever to switch to the specified gear. At shift positions other than the P range, the upper lever portion 20 and the guide groove 76 formed in the detent plate do not match, and the shift lever 10 cannot be bent. When the shift lever 10 is shifted to the P range, the upper lever part 20 tends to fall down due to the spring force of the torsion spring 50, but the guide groove 76
It comes into contact with the slide stopper 80 inside and stops at that position, preventing bending. At this time, the load applied by the torsion spring 50 in the direction of tilting the upper lever portion 20 is received by the detent plate 70 mainly through the plate washer 88 fitted to the knob mounting shaft 82. When bending and tilting the shift lever 10, the operation is as follows. First, shift lever 10 to P range. In this shift position, the upper lever portion 20 of the shift lever
and the guide groove 76 provided on the detent plate,
The shift lever is in a bendable position. However, the shift lever bending operation is prevented by a slide stopper 80. Next, move the stopper release knob 89 to the return spring 87.
along the arcuate groove 79 in the direction of arrow G in FIG. 5 (
(to the rear of the vehicle). Then, slide stopper 8
0 also rotates around the axis OO at the same time, releasing the guide groove 76. When the locking state of the slide stopper 80 is released, the upper lever part 20 is subjected to a force in the direction of tilting by the torsion spring 50, so it falls down naturally at the same time as the slide stopper 80 completes its movement, and the lower end surface of the guide groove 76 It stops when it comes into contact with it. In addition, when the shift lever is tilted, the outer diameter D+ portion of the upper lever part is the groove width W of the guide m76.
3 portion, and then the width across flats 23 of the upper lever portion engages with the groove width W1 portion of the guide groove 76. Therefore, even when the shift lever is in the tilted state, the upper lever portion 20 is held within the guide groove 76 with a slight gap. However, if the parking brake is not operated with the engine running, IGSW124 will turn O
N, PKB link 5W125 is ON on the electromagnetic solenoid 120 side, and the electromagnetic solenoid 120 is ON. As shown in FIG. 16, the plunger 121 is fitted into the locking hole 70d of the detent plate against the compression coil spring 122. As a result, rotation of the slide stopper 80 is prevented by the electromagnetic solenoid 120. In other words, bending of the upper lever portion 20 is prevented. Operate the parking brake (pull the parking brake lever or press the parking brake pedal)
Then, the PKB interlock 5W125 turns ON to the PKB display 5W126 side, and the electromagnetic solenoid 120 turns OFF. Then, the plunger 121 is compressed by the compression coil spring 1.
22, and the locking hole 70d of the detent plate
Then, the locking state of the slide stopper with the locking surface 80d is released. As a result, the slide stopper 80 can be rotated. When the upper lever part 20 falls, the slide stopper 80 rotates about the axis 0-0 by the action of the return spring 87 and returns to the original state shown in FIG. 1 in which the guide groove 76 is closed. When this shift lever 10 is tilted down, is there a guide for the detent plate? The upper lever part 20 is roughly held by the s76 and the inclined surface 80c of the slide stopper, and is further biased by the return spring 87 of the slide stopper to securely hold the upper lever part 20, resulting in high safety. Furthermore, even if the shift lever is tilted with the engine running, the gap between the upper lever portion 20 and the guide groove 76 is small and the return spring 87 biases the shift lever.
The rattling noise between the two is hardly a problem. Then, with the shift lever in the tilted state, the driver's seat is moved, that is, from the driver's seat to the passenger's seat, or from the passenger's seat to the driver's seat. Particularly, in the case of a cab-over type vehicle as shown in FIG. By folding it forward, the shift lever 1O, which is folded down when moving from the driver's seat to the passenger seat, does not get in the way.
It is extremely easy to move seats. In addition, F is the vehicle floor,
H indicates a steering wheel. Furthermore, since the shift lever 10 can only be folded when the shift lever is shifted to the P range, it is possible to fold the shift lever 10 until the engine is started while stopped and leave the driver's seat. Even if part of the body touches -10, the shift lever -10 is reliably held in the P range, so there is no risk of the automatic transmission inadvertently operating. Moreover, since the shift lever 10 cannot be tilted down unless the parking brake is operated, it is possible to prevent forgetting to operate the parking brake, which is safe. In addition, from the appearance, the shift lever 10 is a foldable type,
and its bending direction can be intuitively recognized. Also,
With the simple operation of moving the stopper release knob 89 toward the rear of the vehicle, the upper lever section 20 is automatically collapsed by the spring force of the torsion spring 50, so that the shift lever can be folded very easily. According to this embodiment, the upper lever portion 2 is moved by using the spring force of the detent torsion spring 50.
Since the upper lever part 20 is tilted down, a new spring for tilting the upper lever part 20 is not required, and the upper lever part 20 can be manufactured at a low cost. Further, since the bent portion of the shift lever is covered by the detent plate 70 and the resin cover 90, there is no risk of clothes getting caught on the bent portion when the shift lever is tilted, or of getting dirty with grease applied for lubrication. Next, to return the shift lever 10 to its original state (regular P range), operate as follows. The fallen upper lever part 20 is moved against the torsion spring 50 along the guide groove 76 of the detent plate around the axis Z-Z without operating the stopper release knob 89. Then, as the upper lever portion 20 moves, the slide stopper 80 also rotates around the axis 0-0 by the inclined surface 80c, thereby releasing the guide groove 76. And the upper lever part 20
At the same time as the first
It automatically returns to the original position of blocking the guide groove 76 shown in FIGS. Therefore, the return operation of the shift lever 10 is also extremely easy. [Second Embodiment] FIGS. 17 to 20 show a second embodiment of the present invention, which is an example in which the present invention is applied to a foldable shift lever device for a manual transmission. Fig. 17 is a plan view, Fig. 18 is a sectional view taken along the line X-X in Fig. 17, and Fig. 19 is a section taken from
A cross-sectional view along the line, FIG. 20 is xx-xxv of FIG. 18.
FIG. The shift lever 210 is divided into two parts: an upper lever part 220 including a shift knob and a lower lever part 230 on the transmission side. The lower lever portion 230 includes a fork-like member 231 connected to a control shaft, and a fork-like member 231 connected to the control shaft.
It consists of a pipe-like member 232 welded to the pipe-like member and a sliding member 233 slidably inserted into the pipe-like member. Then, the notched groove formed at the lower end of the upper lever part 220 and the protrusion with the width across flats formed at the upper end of the sliding member 233 are fitted, and the pin 2
0. Connect so that it can be bent. A flange 234 having a substantially rectangular outer shape as shown in FIG. 20 is formed at the lower end of the sliding member 233. As shown in FIG. The pipe-shaped member 232 also has a substantially rectangular cross section, and the two cannot rotate relative to each other. Further, the upper end of the pipe-like member 232 has a circularly enlarged cross section, and a holder 235 is screwed to a female thread formed on the inner peripheral surface thereof. This holder 235 is connected to the upper lever portion 220 and the sliding member 2.
33 has an inner circumferential surface that fits with a slight gap, and constitutes a fixing means for preventing bending of the upper lever portion 220. Furthermore, a compression coil spring 236 is interposed between the flange 234 of the sliding member and the holder 235.
The sliding member 233 is always urged downward. thus,
The joint portion of both lever portions, that is, the bending portion of the shift lever is held in an unbendable position where it fits into the inner peripheral surface of the holder 235. Furthermore, the shift lever bending part has four bolts 25.
It is covered with a bowl-shaped metal cover 270 fixed to a bracket 260 on the vehicle frame side with nuts 251 and 251. This cover 270 is formed with an operation groove 273 that follows the speed change operation pattern of the shift lever. As shown in FIG. 17, the width W1 of the operating groove 273 is set to be slightly larger than the outer diameter of the upper lever portion 220, and the upper lever portion 220 is moved to the first forward speed (
1) to fifth gear (5) and reverse gear (R). Now, a flange-like protrusion 221 having a width W2 larger than the width W of the operating groove 273 formed in the cover is welded to the outer periphery of the upper lever part 220. This flange-like projection 221 is located between the holder 235 and the cover 270. Furthermore, approximately half of the flange-like projection 22i is cut out on the passenger seat side in the selection operation direction. this is,
When the upper lever portion 220 is bent toward the passenger seat side in the select operation direction, the flange-like protrusion 221 closes to the cover 27.
This is to prevent them from interfering with each other when folded toward the driver's seat and when folded in the shift operation direction. Further, at the neutral position of the cover 270, a notch (recess) 271 is provided on the driver's seat side in the selection operation direction, through which the flange-like protrusion 221 can pass. In addition, an upper lever portion 22 is provided on the passenger seat side in the direction of the select operation.
A guide groove 276 is formed that allows 0 bending. Further, an electromagnetic solenoid 280 is attached to the cover 270 to operate the parking brake. The electromagnetic solenoid 280 is in the plunge mode 281 and the compression coil spring? It is equipped with 282. When the electromagnetic solenoid 280 is ON, the plunger 281 is arranged to protrude into the notch 271 against the compression coil spring 281. The electromagnetic solenoid 280 is wired in the same manner as in the previous embodiment (FIG. 16). thus,
When the parking brake is not operated, the upper lever part 22
0, the flange-shaped protrusion 221 of the upper lever part interferes with the plunger 281, and the upper lever part 22
It is designed to prevent the 0 raising operation. Foldable shift lever v of a vehicle transmission having the above configuration
In the apparatus, the bending and returning operations of the shift lever 210 are performed as follows. First, shift lever 210 is operated to the neutral position. Then, the flange-like projection 22 provided on the upper lever part
1 and a notch (recess) 271 formed in the cover are aligned, and the upper lever part 220 can be pulled up. Next, in this state, the upper lever portion 220 is pulled upward against the compression coil spring 236. Then, the joint portion between the upper lever portion 220 and the sliding member 233 by the pin 240, that is, the bending portion of the shift lever moves above the holder 235, and the shift lever 210 becomes a bendable position. However, if the parking brake is not operated with the engine running, the electromagnetic solenoid 280 turns OFF.
The plunger 281 protrudes against the compression coil spring 282. As a result, the flange-like protrusion 221 of the upper lever interferes with the plunger 281 of the electromagnetic solenoid, causing the upper lever 220 to interfere with the plunger 281 of the electromagnetic solenoid. A pulling-up operation is not possible, that is, bending of the upper lever portion 220 is prevented. On the other hand, when the parking brake is operated, the electromagnetic solenoid 280 is turned off, the plunger 281 is returned by the compression coil spring 282, and the upper lever portion 22
0 raising operation becomes possible. Subsequently, in this state, the upper lever portion 220 is bent toward the axis in the selection operation direction as shown by the imaginary lines in FIGS. 17 and 18. In addition, when returning the shift lever 210 to its original state, by placing the upper lever part 220 in an upright state, the restoring force of the compression coil spring 236 automatically returns it to the position where it cannot be bent by the holder 235 shown in FIG. do. and,
During normal gear shifting operations, the holder 235 prevents the upper lever portion 220 from bending, and the flange 220 is prevented from bending.
34 and the inner circumferential surface of the pipe-like protrusion 232, the shift lever receives an operating force and is operated in the same manner as a conventional shift lever. This embodiment also provides the same effects as the first embodiment described above. The present invention has been described in detail with respect to specific embodiments, but
The present invention is not limited to the above embodiments, but includes various embodiments within the scope of the claims. It is also possible to arrange it so that.

【Effect of the invention】

As explained above, according to the present invention, since the shift lever is bent and tilted toward the passenger seat only at a predetermined position, the folded upper lever portion and shift knob do not protrude. Therefore, the seat does not get in the way when moving the seat, making it extremely easy to move the seat inside the vehicle. Furthermore, if the parking brake is not operated, the shift lever will
Since it is made so that it cannot be tilted, it is possible to prevent forgetting to operate the parking brake, making it extremely safe.
