Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a locking device for a vehicle glove box.

As a conventional locking device for a vehicle glove box, for example, there is one as shown in FIGS.

That is, in these drawings, 1 is an instrument panel, 2 is a glove box provided on one side of the instrument panel 1, and 3 is a glove box 2 whose lower end is pivotally supported by the instrument panel 1 so as to be openable and closable. The lid 4 is a lock device incorporated in the upper side end of the lid 3.

The locking device 4 includes a base member 5 fixed to the lid 3, an operation knob 6 whose upper end is rotatably supported by the base member 5, and a base end fixed to the back surface of the operation knob 6. A swing arm 7 that swings integrally with the operation knob 6, a key cylinder housing 8 fixed to the base member 5 and the lid 3, and a key (not shown) pivotally supported by the key cylinder housing 8. ) And a linkage lever 11 whose base end is supported by the rear end of the key cylinder 10 and which rotates together with the key cylinder 10 and whose front end faces the swing arm 7. Similarly, the base end is supported on the rear end of the key cylinder 10 and the linkage lever 11
A driven lever 12 which rotates integrally with the sliding lever 5 and a bent engaging portion 15a facing the driven lever 12 at one end, and the base of the engaging portion 15a is formed in the base member 5 by a sliding groove 5a. An operating rod 15 which is swingably engaged with the slider 14 by means of a slider 14; and the glove box which is connected to the other end of the operating rod 15 and pivots about a pivot shaft 16 by reciprocal movement of the operating rod 15. It is constituted by a fork member 17 which is engaged with and disengaged from a striker (not shown) provided on the inner wall of 2, and is constantly urged by a spring (not shown) in a direction to engage with the striker.

In addition, 3a is an escutcheon portion that is recessed in the lid 3 and that accommodates the operation knob 6, 3b is a mounting hole of the key cylinder housing 8 that is also opened in the lid 3, and 5b
Is a through groove of the swing arm 7 formed in the base member 5.

When the lid 3 is normally closed and the key lock is off, pulling the lower end of the operation knob 6 forward with a finger causes the operation knob 6 to be closed.
Rotates, and the swing arm 7 integrated with this also rotates. As a result, the linkage lever 11 facing the tip of the swing arm 7 rotates (in the direction of the arrow in FIG. 7), and the driven lever 12 is integrated with this.
Also in the same direction, the bending engagement portion 15a of the operating rod 15 facing this slides in the sliding groove 5a, the operating rod 15 moves forward, and the fork member 17 rotates. The engagement with the striker is released and the lock is released. Therefore, the lid 3 can be opened in this state.

On the other hand, when the lid 3 is key-locked in the closed state, the key cylinder 10 is placed at a specific rotational position, and the linkage lever 11 and the driven lever 12 which are integral with the key cylinder 10 are shown by a chain double-dashed line in FIG. 7 or 8. In this state, that is, when the swing arm 7 swings, the swing lever 7 is fixed in a position where it does not come into contact with the linkage lever 11, and the fork member 17
Remains in engagement with the striker. in this case,
Even if the operation knob 6 is rotated, the swing arm 7 that swings integrally with the operation knob 6 does not come into contact with the linkage lever 11 as shown in FIG. 8, that is, the operation knob 6 swings so-called. The lid 3 remains closed. An escape space S is set between the swing arm 7 and the link lever 11 so that the link lever 11 does not come into contact with the swing arm 7 when the key is rotated.

A technique similar to the above configuration is disclosed in, for example, Japanese Utility Model Laid-Open No. 62-193067.

[Problems to be solved by the device]

However, in such a conventional structure, since the escape space S is set between the swing arm 7 and the linkage lever 11, when the lid 3 is opened in the key lock-off state, the operation knob 6 is rotated. When the swing arm 7 swings with the movement, it does not come into contact with the linkage lever 11 in the section of the stroke a in FIG. 7 corresponding to the escape space S at the beginning. In the section of the stroke b until the arm 7 comes into contact with the linkage lever 11 and the fork member 17 comes out of the striker, the operation force of the operation knob 6 needs to be as large as necessary to remove the fork member 17 from the striker. .

That is, the operating force of the operating knob 6 changes on the way. Therefore, there is a problem that the operation feeling of the operation knob 6 is bad.

The present invention has been made in view of such conventional problems, and an object thereof is to provide a locking device for a vehicle glove box in which the operation feeling of the operation knob is improved.

[Means for Solving the Problems]

In order to achieve such an object, the present invention comprises a swing arm that swings integrally with an operation knob, and a linkage lever having a tip of the swing arm facing the tip and supported by a key cylinder. In a lock device in which a lid of a glove box is unlocked by rotating a knob, a spacer having a base pivotally supported by the swing arm and a tip end engaged with a tip end of the linkage lever is provided. It is provided.

[Action]

When the operation knob is rotated with the key lock off, the swing arm that is integral with this swings, and the spacer pivotally supported at the tip of this swing arm also swings and moves downwards, As a result, the linkage lever engaged with the tip of the spacer rotates, and the lid of the glove box is unlocked. In this case, the operating force of the operating knob is always constant because the spacer is interposed between the tip of the swing arm and the tip of the linkage lever.

On the other hand, if the operation knob is rotated with the key locked,
The linkage lever remains stationary at a specific position, but as a result of the swing lever swinging, the spacer rotates in the direction opposite to the above while slidingly contacting the tip of the linkage lever, so that the operating lever is in the idle state. Become.

〔Example〕

Hereinafter, the same parts as those in the related art will be described with the same reference numerals with reference to the drawings.

Since the basic structure of the present invention is the same as that of the conventional example, the description will be omitted.

In the present invention, as shown in FIG.
A base portion of a spacer 20 having a substantially rectangular shape and a curved lower end is pivotally supported by a pivot shaft 21 at the tip of an oscillating arm 7 integrated with the pivot arm 21.

On the other hand, an engaging groove 22 extending in the width direction of the linking lever 11 is formed at the tip of the linking lever 11 facing the swing arm 7, and the curved tip of the spacer 20 is formed in the engaging groove 22. It is engaged so that it can rotate and slide.

The pivot shaft 21 is arranged substantially in the longitudinal direction of the swing arm 7. That is, the spacer 20 is rotatable in a direction coinciding with the rotating direction of the link lever 11.

The length of the spacer 20 is set so that the tip of the spacer 20 abuts the tip of the linkage lever 11 when the key is locked at the maximum swing position of the swing arm 7.

With such a configuration, the operation knob 6 with the key locked off
As shown in FIG. 2, when the swinging operation is performed, the swinging arm 7 integrated with it swings as shown by the arrow a, and the spacer 20 pivotally supported at the tip of the swinging arm 7 also moves by the arrow b. While rotating in the counterclockwise direction indicated by, it moves down integrally. As a result, the linkage lever 11 engaged with the tip of the spacer 20 also moves into the spacer 20.
The fork member 17 is separated from the striker at the maximum swing position of the swing arm 7 indicated by the chain line to release the lock, and the lid 3 can be opened. During the turning operation of the operation knob 6, since the spacer 20 is always interposed between the tip ends of the swing arm 6 and the link lever 11, the operation knob 6
The operating force of is constant and does not change from the beginning to the end of rotation, and therefore the operating feeling is good.

On the other hand, in the key-locked state, the spacer 20 whose tip is engaged with the engagement groove 22 of the linkage lever 11 is
3 together with the linkage lever 11 which rotates together with the rotation, rotates in the clockwise direction shown by the arrow c in FIG. 3 so that its tip is separated from the engagement groove 22 and the side surface 20a slides on the tip of the linkage lever 11. Come into contact. When the operation knob 6 is rotated, the linkage lever 11 remains fixed at a specific position as shown in FIG. 3, but the swing arm 7 swings in the direction of the arrow a as described above. As a result, the side surface 20a of the spacer 20 is brought into sliding contact with the tip of the linkage lever 11, and reaches the position shown by the chain line at the maximum swing position of the swing arm 7. Therefore, when the key is locked, the spacer
Since 20 rotates and does not transmit the movement of the swing arm 7 to the linkage lever 11, the operation lever 6 is in a so-called idle state.

FIG. 4 shows another embodiment of the present invention.

In this embodiment, when the oscillating arm 7 reaches the maximum oscillating position indicated by the chain line, a stopper 24 for preventing the oscillating arm 7 from rotating is prevented from rotating further so that the spacer 20 does not rotate further. It is formed on the part.

〔effect〕

As described above, according to the present invention, the swing arm integrally swings with the operation knob, and the linkage lever having the tip of the swing arm facing the tip and supported by the key cylinder. In a lock device configured to unlock a lid of a glove box by rotating the operation knob, a base portion is rotatably supported by the swing arm and a tip end thereof is engaged with a tip end of the linkage lever. Since the spacers are provided, the operation feeling of the operation knob is improved.
