Description

[Detailed explanation of the idea] The present invention relates to a locking mechanism for a grab door.

As a locking mechanism for a grab door that is pivotally attached to an instrument panel inside the driver's seat of a car, it has a lock bar that slides up and down within the main body attached to the grab door by rotating a manual handle. There is something. This lock mechanism engages and locks a striker fixed to the frame of the automobile in a space formed by the lock bar and a hook protruding from the main body, and the lock bar is pulled down by the manual handle. to release the lock.

Therefore, the locking mechanism is effective as long as the sole purpose is to prevent the glove door from dislodging from the opening of the glove box while the vehicle is in motion. However, when storing small items such as valuables in a grab box, a separate locking mechanism is required, which can be locked with a key. However, it is preferable that this separate locking mechanism is formed so that the entire structure including the locking mechanism is made smaller and lighter.

Therefore, an object of the present invention is to provide a grab door locking mechanism devised from this viewpoint.

According to the grab door lock mechanism of the present invention, a long hole extending vertically and penetrating horizontally is provided in the lock bar and the main body slidably supporting the lock bar. This through hole has one end that is
A locking plate is passed through which engages a crank formed in the rotor of the cylinder lock. The other end of the locking plate is engaged with a pawl of the manual handle when the cylinder lock is in the unlocked state, and is disengaged when the cylinder lock is in the locked state.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the locking mechanism of the present invention includes a main body 12 attached to a glove door 10.
A striker 18 is installed in the space formed by the lock bar 14 and the hook 16, which are supported by the lock bar 14 and move up and down.
It is engaged and locked.

The glove door 10 is pivotally connected to an instrument panel (not shown) at its lower end. Main body 1 attached to this grab door 10 and moving together with this grab door 10
2 is a bottomed rectangular tube with a substantially square horizontal cross section, and a hook 16 is integrally provided on one wall 20 of the tube.

The lock bar 14 has a support portion 15 whose horizontal cross section is substantially square and whose swings in the front and rear and left and right directions are restricted by the four walls of the main body 12 and which is movable in the vertical direction. This support portion 15 is provided with a long hole 22 . This elongated hole 22 extends in the vertical direction, that is, the long axis of the elongated hole 22 is arranged vertically, and is penetrated in the horizontal direction. The upper end of the lock bar 14 has a rear side surface 25 extending from the side surface 24 of the lock bar 14 facing the wall 20 to the rear side surface 25.
5, a curved surface 26 is formed such that the distance from the lower end of the support portion 15 becomes smaller as it approaches 5, and the side surface 24
A groove 27 extending over the lower end of the support portion 15 is formed in the center of the support portion 15 . The curved surface 26
0 into the opening of the glove box, if you push it hard, it will come into contact with the striker 18,
This striker 18 serves to push down the lock bar 14 into the body 12. A coil spring 28 is disposed between the groove 27 and the bottom wall 21 of the main body 12, biasing the lock bar 14 upward. Thus, upward movement of the lock bar 14 is inhibited by a locking plate and a manual handle, which will be described later.

As shown in FIG. 3, the hook 16 has a substantially C-shaped vertical section, and a groove 3 extending over the entire width W of the hook 16 is formed on the side surface 17 facing the lock bar 14.
0 is set. As a result of providing the groove 30 in the hook 16 in this way, when the lock bar 14 protrudes upward, the side surface 24 of the lock bar 14 and the side surface 17 of the hook 16 come into contact, and the groove 30 forms a space with open ends in the width direction. becomes. In the locked state, the striker 18 is located within this space. This striker 18 is supported on both sides and fixed to a suitable member such as the frame 32 of the automobile.

The cylinder lock 34 consists of a casing 36 fixed to the main body 12 and a rotor 38 rotating within the casing 36. The rotor 38 is formed with depressions and depressions 40 corresponding to the depressions and depressions of the key inserted into the rotor, and when the two match, the rotor 38 is rotated. A crank 42 is provided at one end of the rotor.

A locking plate 44 is engaged with the cylinder lock. An end 45 of the locking plate 44 is substantially circular as shown in Fig. 2, and a long hole 46 is provided in the radial direction from the center of the circle.
The long hole 46 is formed in the rotor 38 of the cylinder lock 34.
A crank 42 provided on the shaft is loosely inserted into the shaft.

Two side walls 5 perpendicular to the wall 20 of the main body 12
0,51 is provided with a long hole 52, and the other end 47 of the locking plate 44, which passes through this long hole 52 and the long hole 22 of the lock bar 14, is located on the side opposite to the cylinder lock 34 from the main body 12. It is projected to. The locking plate 44 is rotated from a substantially horizontal position to a position diagonally downward and close to the bottom wall 21, as shown by solid lines and imaginary lines in FIG.
Therefore, the elongated holes 52 in the side walls 50, 51 have a length over this range. On the other hand, the elongated hole 22 provided in the locking bar 14 has an inclined surface 23 so that it can fit well into the elongated hole 22 of the locking bar 14 when the locking plate 44 reaches the lower limit position, as shown in phantom in FIG. It is formed as having the following.

A manual handle 54 is used to raise and lower the lock bar 14. A bracket 56 provided on the manual handle 54 is fixed to a shaft 60 rotatably supported by two bearings 58 integrally projecting from the main body 12, as shown in FIG. A spring 62 is wound around this shaft 60, one end of the spring 62 is locked to the ceiling of the manual handle 54, and a central part 63 of the spring 62 is attached to the hook 1.
6, the other end of the spring rests against the hook of the lock bar 14. The spring 62 biases the manual handle 54 counterclockwise in FIG. 3, and the pawl 55 protruding from the handle 54 comes into contact with the wall at the upper end of the lock bar, thereby preventing further rotation. The central portion 63 of the spring 62, which is disposed in the groove 64 of the hook, clamps the striker 18 in cooperation with the side surface 24 of the locking bar 14.

The pawl 55 of the manual handle 54 engages the end 47 of the locking plate 44 when the cylinder lock 34 is unlocked, as shown in FIG. Therefore, when the manual handle 54 is rotated, the pawl 55 pushes down the locking plate 44, so that the lock bar 14 slides inside the main body 12 and is pushed down. This opens the grab door. Next, when the cylinder lock 34 is placed in the locked state, the locking plate 44 is moved to the left as shown by the imaginary line in FIG. The dimensions of the locking plate 44 and crank 42 are determined in advance. As a result, even if the manual handle 54 is rotated, the pawl 55 does not engage with the locking plate 44, so the locking bar 1
4 is maintained in an upwardly protruding state.

According to the present invention, the cylinder lock is supported by the main body, one end of the locking plate is engaged with a crank provided on the rotor of the cylinder lock, and the other end of the locking plate is made to protrude from the main body and the lock bar. Since it is engaged with the pawl of a manual handle, the overall size and weight are reduced. Therefore, cost reduction is possible.
