Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION When an automobile is stopped, a side brake works, and a key is often removed to be carried by a driver. In addition to the side brakes, in order to prevent the automobile from moving, it is known to operate the gear change lever to move it to the 1st speed or the R position and keep the gears connected in the hill parking. Further, in AT vehicles, the shift lever is normally set to the parking position. The present invention relates to a vehicle start prevention device including these mechanisms.

[0002]

2. Description of the Related Art Each car has its own key,
By inserting the key into a predetermined position, the lock of each part is released, and the engine can be started and started. At this time, the side brakes are normally working to prevent the vehicle from starting. Therefore, the knob button provided at the tip of the brake lever is pushed to tilt the brake lever and release the side brake. Further, in an AT vehicle, since the shift lever is normally in the parking position, the knob button provided on the shift lever is pushed to move the shift lever to the first speed position or the drive position.

When the vehicle is parked, all the knob buttons lock the brake lever and the shift lever, so that the stopped state is maintained, but an occupant waiting in the vehicle (or a child left in the vehicle, etc.) accidentally touches it. If these knob buttons are pressed, the lock may be released. Therefore, it has been proposed to lock the knob button by utilizing the shape of the knob button (cylindrical body with the tip closed) (see Japanese Utility Model Laid-Open No. 63-149327). That is, a button body having an open tip and a substantially disc-shaped lid are divided into a key groove formed inside the button body, and a lid provided with a key is incorporated. With this structure, the knob button is locked when the lid is removed.

Further, there is one in which a protrusion is formed on the outer peripheral surface of the base of a knob button inserted into the grip at the tip of the brake lever and a recess is formed on the inner peripheral surface of the grip (Japanese Utility Model Laid-Open No. 63-195956). reference). In this structure, normally, the protrusion of the knob button and the recess in the grip are separated, but when the knob button is rotated to engage the protrusion and the recess, the knob button is locked. This prevents the brake lever from being unlocked.

When moving a car without a key,
It is known to short the cord of the ignition motor, but it is inconvenient and time-consuming to operate the knob button. Therefore, it is possible to prevent mischief and theft.

[0006]

The knob button provided on the brake lever and the knob button provided on the shift lever have their own lock mechanism, but the key with the lid of the brake lever uses the cylinder mechanism as the button body. It is complicated and expensive. Further, in the case of rotating the knob button to lock it, there is a possibility that the lock is released while the knob button is being messed up. The method of locking these knob buttons has a problem that it is costly or that the locking method is simple and can be operated by another person.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle start preventing device in which a knob button provided on a brake lever and a knob button provided on a shift lever are locked by a simple means and cannot be operated easily.

[0008]

In order to achieve the above-mentioned object, the present invention divides a lock knob button attached to an operating lever into an outer part and an inner part in the pushing direction and separates them by an engaging means. Integrated as much as possible,
It is characterized in that the joint surface of both parts is inside the surface of the operating lever.

Further, in the above device, the outer part can be attached to the key holder, the accessory or the like through the engaging means formed on the outer part.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The operating lever in an automobile refers to a brake lever of a side brake in an MT vehicle.
In automatic transmissions, the shift lever is also an operating lever.
Both are equipped with a lock knob button. When the lock knob button is pressed, it enters the operation lever, and when the hand is released, it returns to its original position due to the biasing force of the spring, and the lock knob button projects from the surface of the operation lever.

The knob button is divided into a front part and a rear part with respect to the entering direction, and is composed of an outer part and an inner part. When the knob button is spring-biased, the boundary surface between the two parts is located inside the knob button surface when the knob button is in the projecting state, and the inner part is left inside the operating lever when the outer part is removed. Therefore, the operating lever cannot be released from the locked state without moving the knob button.

The engaging means between the outer part and the inner part is a screw, a snap (fitting a projection, a C ring, an O ring, a ball, etc. in a recess), and the knob button is made of metal or synthetic resin depending on strength. To do. Further, the outer part may be pulled out and removed as it is, or may be pulled out after the fitting portion is rotated. Further, the outer part when removed is mounted on a key holder, an accessory or the like having a similar engaging means and stored together with the key.

[0013]

Embodiments of the present invention will be described below with reference to the accompanying drawings. Since the shift lever of the AT vehicle is also targeted here, the description of the MT vehicle will be omitted. In an AT vehicle, as shown in FIG. 7, an instrument panel 2 and a steering wheel 3 are arranged in front of a driver's seat 1, and a shift lever 4 and a brake lever 5 are arranged laterally.

As shown in FIG. 1, the shift lever 4 comprises a pipe 7 inserted into a select groove 6 and a select knob 8 attached to the tip thereof, and a hole 9 is formed in the side surface of the select knob 8.
The knob button 12 including the inner part 10 and the outer part 11 is inserted so that the knob button 12 is inserted. As shown in FIGS. 2 and 3, the inner part 10 has an inclined surface 10a at the rear end,
A protrusion 13 for retaining is formed on the outer periphery of the side surface, and a screw 10b is formed in an inner hole facing the outside. A screw 11a is formed on the outer peripheral surface of the insertion part of the outer part 11, and the outer part 11 is screwed by this. With the knob button 12 protruding, the joint surface 10c of the inner part 10 with the outer part 11 is located deeper than the surface of the select knob 8.

The inclined surface 10a of the inner part 10 of the knob button 12 is in sliding contact with the tip of the select rod 14 in the pipe 7, and by pressing the knob button 12, the select rod 14 moves to unlock the shift lever 4.

The knob button 12 described above makes the shift lever 4 inoperable by removing the outer part 11 when the shift lever 4 is locked. Also,
As shown in FIG. 4, the removed outer part 11 has good functionality and can be prevented from being lost by carrying it together with the key 16 in a dedicated key holder 15. Further, instead of the key chain 15, it may be attached to an accessory or the like.

Further, when the vehicle is parked and parked and the driver leaves the car, the shift lever 4 is moved to the "P" position to remove the outer part 11 of the knob button 12, and the driver takes out the outer part 11 together with the key 16. Even if a child kept waiting in the vehicle mischiefs the peripheral device, the brake of the vehicle is not easily released and the vehicle is prevented from moving because the outer part 11 is removed. Also, whether or not the knob button 12 is worn can be determined from the outside, and if it is not worn, it is expected that it will take time to start, or it will be mistaken for a broken car, so it will be stolen by an external person. Less often. Even when stolen, the outer part 11 of the knob button 12 is not attached to the shift lever 4 in many cases, or is not aligned with each other, so that the shift button is easily found.

In the knob button 12 shown in FIG. 5, a groove 10d is formed on the inner peripheral surface of the hole of the inner part 10 and an annular groove 11b is formed on the outer peripheral surface of the insertion part of the outer part 11, thereby forming a C ring (snap ring).
It is equipped with 17. As a result, the outer part 11 can be detached with one touch, and the troublesomeness of the detaching operation is eliminated.

Next, the brake lever 5 will be described. As shown in FIG. 6, a rod 18 is inserted into the inside of the brake lever 5, the inner part 10 of the knob button 12 is fixed to the tip of the rod 18, and the positioning is made by a spring 19. The joint surface 10c of the inner part 10 with the outer part 11 has a brake lever 5
Is located deeper than the tip of the screw, and the screw 10b is
Are formed. The outer part 11 has a screw 11 on the outer peripheral surface of the insertion part.
a is formed and is attached to the inner part 10 by screws 10b, 11a. When the outer part 11 is removed, the knob button 12 does not move and the brake lever 5 cannot be operated. Therefore, like the shift lever 4 described above, the brake lever 5 cannot be tampered with, which also serves to prevent theft. In particular, in a car with a hood or the like, the side brake is locked by a key cylinder or the like, but even if the knob button 12 is removed, the brake cannot be released and theft is prevented.

[0020]

Since the present invention is constructed as described above, it is possible to prevent mischief and theft by simply manufacturing the knob button by dividing it into an inner part and an outer part. It can be equipped and the cost can be reduced. In addition, the outer part can be matched to the user's taste by arranging various colors and shapes as a single item, and when the removed outer part is attached to the car key chain, accessories, etc., when only the key is attached Compared with, you can immediately determine which car it belongs to and you do not have to worry about losing it.
