Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glove box slide lock for an automobile which is unlocked by turning a key.

Conventionally, this type of glove box slide lock has had the disadvantage that it is necessary to use a key to lock the lock, making the operation cumbersome.

The present invention focuses on this drawback, and its purpose is to simply push the knob cylinder in the axial direction without using a key when locking.
Moreover, it is possible to do this simply by rotating it.

One embodiment of the present invention will be described below with reference to the drawings. On the rear end side of a cylinder case 1 provided in a glove box, a locking element 8 is provided in a manner that can be retracted from the rear end of a cylinder case 1 provided on the outer peripheral surface. It is biased in the protruding direction by a spring 7 loaded therebetween, and when protruded, it engages with a strike (not shown) of the glove box.

Knob cylinder 2 on the inner surface of cylinder case 1
is rotatably fitted into the cylinder case 1, and a spring 9 inserted into the cylinder case 1 biases the front surface of the knob cylinder 2 in the direction of protruding from the glove box slide.

A driving portion 11 that engages with the locking element 8 is provided at the rear end of the knob cylinder 2 .

There is a key insertion hole 10 on the front of the knob cylinder 2.
is provided on the outer circumferential surface of the knob cylinder 2 so that the tumbler 3 is biased in the direction of protrusion. The knob cylinder 2 becomes rotatable.

As shown in Figure 3, the tumbler 3 is in the unlocked position A.
When the tumbler 3 is in the locking position B, the driving part 11 provided at the rear end of the knob cylinder 2 retracts the locking element 8, and when the tumbler 3 is in the locking position B, the driving part 11
The disengaged locking element 8 protrudes and engages with the glove box, and at the neutral position C between the unlocked position A and the locked position B, the cut groove 5 to be described later
can be moved in the axial direction by

There is a tumbler groove 4 on the inner surface of the cylinder case 1.
The tumbler groove 4 is formed with a slope 4a that becomes shallower from the neutral position C toward the locking position B, allowing the tumbler 3 to sink into the knob cylinder 2, and is formed so that the tumbler 3 protrudes again at the locking position B. has been done. Further, as shown in FIG. 1, the cut grooves 5 provided in the cylinder case 1 include a vertical groove 5c provided at the neutral position C and a vertical groove 5c provided along the circumferential direction from the rear end of the vertical groove 5c. It is constituted by a locking guide groove 5b and an unlocking guide groove 5a provided along the circumferential direction from the front end of the vertical groove 5c.

And the pin 6 provided on the knob cylinder 2
is at the end of the unlocking guide groove 5a, the tumbler 3 is between the unlocking positions A, and the drive unit 11 causes the locking element 8 to sink into the knob cylinder 2, but the pin 6 is in the vertical groove 5c. At times, the tumbler 3 is in the neutral position C, the knob cylinder 2 is movable parallel to the longitudinal groove 5c, and the pin 6 is in the locking guide groove 5b.
When the tumbler 3 is at the end of the
, the knob cylinder 2 cannot be rotated counterclockwise in FIG.
The locking element 8 engages with the glove box.

Therefore, rotate the unlocked knob cylinder 2 to align the tumbler 3 to the neutral position C, push the knob cylinder 2 against the spring 9, and then move the tumbler 3 to the locked position B. When the glove box is rotated, the locking element 8 engages with the glove box and the glove box slide lock is locked, so that locking can be performed without using a key.

As shown in FIG. 2, the case where the cut groove 5 is provided in the knob cylinder 2 is also similar to the above.

As described above, the present invention has a tumbler groove formed in the inner wall of the cylinder case that contacts the protruding tumbler when the knob cylinder is rotated in the locking direction, so the knob cylinder can be rotated without using a key. Therefore, the locking operation can be performed easily and quickly.

Claims (1)

[Claims] 1 A cylinder case provided on the glove box slide, a locking element biased toward the rear end side of the cylinder case in a direction protruding from the outer peripheral surface of the cylinder case, and a locking element rotatably provided within the cylinder case. a knob cylinder which has a driving part that engages with the locking element at its rear end and is biased toward the distal end; and a knob cylinder that is formed on the inner surface of the cylinder case and that is removable from the outer peripheral surface of the knob cylinder. In an automobile glove box slide lock having a tumbler biased in a direction to engage a tumbler groove, either one of the cylinder case and the knob cylinder is provided to guide the knob cylinder in the neutral position to move in the axial direction. A cut groove is provided, which is composed of a vertical groove, a locking guide groove connected to the rear end of the vertical groove, and an unlocking guide groove connected to the front end of the vertical groove, and the other part is engaged with the cut groove. A glove box slide lock for an automobile, characterized in that a matching pin is provided, and the tumbler groove is provided with a slope that becomes shallower from the neutral position of the knob cylinder toward the locking position, into which the tumbler is immersed.
