Description

  The present invention relates to a locking device for a glove box.

8 to 12 show a conventional glove box locking device.
As shown in FIGS. 8 and 9, the conventional glove box locking device includes a housing 2, a stay 3 that includes a slope portion 3 a and can reciprocate in the horizontal direction with respect to the housing 2, and can rotate to the housing 2. The knob 4 is attached to the knob 4, the key cylinder 5 is attached to the knob 4, and the rod 6 is attached to the stay 3. The housing 2, stay 3 and knob 4 are made of resin, and the key cylinder 5 is made of metal.
The key cylinder 5 includes an outer cylinder 5a that is fixedly attached to the knob 4 and an inner cylinder 5b that is rotatable with respect to the outer cylinder 5a. As shown in FIG. 12, the inner cylinder 5b is provided with a protrusion 5c. The protrusion 5c is movable to a key lock release position and a key lock position rotated 90 degrees from the key lock release position with respect to the knob 4 by inserting a key (not shown) into the key cylinder 5 and turning the key. It is.
As shown in FIG. 10, the protrusion 5 c is located above the slope 3 a of the stay 3 when in the key unlock position, and deviates from the position above the slope 3 a of the stay 3 when in the key lock position. In the position.
When the protrusion 5c is in the key lock release position (when the key lock is released), when the knob 4 is pulled, as shown in FIG. 11, the key cylinder 5 rotates with the knob 4 in the knob pulling direction, and the protrusion 5c is inclined. It hits part 3a. When the knob 4 is further pulled, the protrusion 5c slides down the slope 3a, and the stay 3 moves in the horizontal direction. As a result, the rod 6 moves, the rod 6 comes out of the hole provided in the instrument panel, and the glove box can be opened.
When the protrusion 5c is in the key lock position (when the key is locked), even if the knob 4 is pulled, the protrusion 5c does not hit the inclined portion 3a (is swung). As a result, even if the knob 4 is pulled (the knob 4 is turned), the stay 3 cannot be moved and the glove box cannot be opened.

However, the conventional glove box locking device has the following problems.
(A) Since the knob 4 can be rotated even when the glove box cannot be opened at the time of key lock, the user may feel uneasy about whether it is really locked.
(B) (b-1) Since the projection 5c of the key cylinder 5 slides on the slope 3a of the stay 3, the key cylinder 5 is not only locked / unlocked of the glove box, but also the slope 3a of the stay 3. It must be arranged in consideration of sliding. For this reason, there are many restrictions on the arrangement position of the key cylinder 5. Therefore, it is difficult to increase the amount of lap in the vehicle front-rear direction between the protrusion 5c and the slope 3a when releasing the key lock. Further, (b-2) the key cylinder 5 has a play (gap between the inner and outer cylinders 5a and 5b) necessary for the function.
As a result, as shown in FIG. 12, when the knob 4 is pulled, the protruding portion 5c gets over the inclined surface portion 3a (disengaged from the inclined surface portion 3a) even though the protruding portion 5c is in the key lock release position. There is a risk. If the protrusion 5c gets over the slope 3a, the stay 3 cannot be moved and the glove box cannot be opened.

A first object of the present invention is to provide a glove box locking device capable of fixing a knob at the time of key lock.
The second object of the present invention is to provide a glove box locking device that can reliably open the glove box when the key lock is released.

The present invention for achieving the above object is as follows.
(1) a housing;
A stay having a slope portion and a contact portion and movable relative to the housing;
A knob movable relative to the housing;
A knob protrusion that is provided integrally with the knob and that slides on the slope portion of the stay when the knob is operated to move the stay relative to the housing;
The knob is attached to the knob, and includes a protrusion, the protrusion being in contact with the abutting portion of the stay and disabling operation of the knob, and coming off from the abutting portion of the stay. A key cylinder movable to a key unlocking position enabling operation of the knob; and
A glove box locking device.
(2) The glove box locking device according to (1), wherein the slope portion of the stay and the knob protrusion are made of resin.

In the glove box locking device of the above (1), the following actions and effects can be obtained.
(A) Since the key cylinder is attached to the knob, and the protrusion of the key cylinder comes into contact with the abutting portion of the stay and is movable to the key lock position that disables the knob operation, the knob is locked when the key is locked. The knob cannot be moved relative to the housing by pulling. Therefore, the knob can be fixed when the key is locked.
(B) (b-1) A knob projection sliding with the slope portion of the stay is provided, and the projection of the key cylinder is movable between a key lock position and a key lock release position. For this reason, the knob protrusions need only be arranged in consideration of sliding on the slope of the stay (it is not necessary to arrange them in consideration of the lock / unlock of the glove box), and the key cylinder is the glove box. It is only necessary to be arranged in consideration of the lock / unlock of this (it is not necessary to be arranged in consideration of sliding on the slope of the stay). Therefore, there are few restrictions on the position of the knob projection and the key cylinder. Therefore, the amount of wrap between the knob protrusion and the slope portion can be increased. Further, (b-2) since the knob protrusion is provided integrally with the knob, the knob protrusion does not have a play (gap between the inner and outer cylinders) necessary for the function unlike the key cylinder. Therefore, when the knob is operated when the key lock is released, it is possible to prevent the knob protrusion from getting over the slope (disengaged from the slope), and the glove box can be opened reliably by operating the knob when the key is released. be able to.
In the glove box locking device of (2) above, the slope of the stay and the knob projection are made of resin, so even if the knob projection slides on the slope of the stay, the knob projection may damage the slope of the stay. It is possible to prevent cutting.

1 to 7 show a glove box locking device according to an embodiment of the present invention.
A glove box locking device (hereinafter simply referred to as a locking device) 10 according to an embodiment of the present invention is a vehicle glove box locking device.
The locking device 10 is attached to a vehicle glove box 80 shown in FIG. The glove box 80 rotates by its own weight around the rotational axis at the lower end of the glove box 80 and opens, and when it is closed, the glove box 80 is lifted by hand around the rotational axis at the lower end of the glove box 80.
The locking device 10 is disposed in a recess 81 provided in the glove box 80. As shown in FIG. 1, the locking device 10 includes a housing 20, a stay 30 movable with respect to the housing 20, a knob 40 movable with respect to the housing 20, a knob protrusion 50 provided on the knob 40, and a knob 40. And a rod 70 (see FIG. 7) that moves together with the stay 30.

  The housing 20 is made of resin. The housing 20 is fixed with respect to the glove box 80. The housing 20 may be formed integrally with the glove box 80 or may be formed separately from the glove box 80 and fixedly attached to the glove box 80.

The stay 30 is made of resin. The stay 30 is supported by the housing 20 so as to be slidable in the left-right direction. The stay 30 includes a first stay 31, a second stay 32, and a gear 35 that is attached to the housing 20 and moves the first and second stays 31, 32 synchronously in opposite directions in the left-right direction. Prepare.
As shown in FIG. 2, one of the first and second stays 31 and 32 includes a slope portion 33 and a contact portion 34. Hereinafter, the case where the slope part 33 and the contact part 34 are provided in the 2nd stay 32 is demonstrated.
The slope portion 33 and the contact portion 34 are provided on the side surface of the knob 40 of the second stay 32.
The slope portion 33 is inclined linearly upward and to the right of the vehicle as viewed from the rear of the vehicle (as viewed from the knob 40 side).
The contact portion 34 is provided at a position different from the slope portion 33 in the vehicle left-right direction. The abutting part 34 is a flat part extending in a horizontal direction (substantially including the horizontal direction) orthogonal to the vertical direction. The length of the abutting portion 34 in the left-right direction of the vehicle may be the same as the plate thickness of a later-described protrusion 63 of the key cylinder 60, but is preferably larger than the plate thickness.

  The knob 40 is made of resin. As shown in FIG. 3, the knob 40 is movably attached to the housing 20. The movement of the knob 40 relative to the housing 20 is rotation (may be swinging). The knob 40 rotates with respect to the housing 20 by pulling the lower end of the knob 40 rearward and upward. When the knob 40 is operated, the knob 40 rotates around an axis provided at or near the upper end of the knob 40. As shown in FIG. 1, the knob 40 includes a knob biasing spring 41. The knob biasing spring 41 constantly biases the knob 40 with respect to the housing 20 in a direction to return to a state before the lower end of the knob is pulled up.

  The knob protrusion 50 is made of resin. The knob protrusion 50 is provided integrally with the knob 40. The knob protrusion 50 may be formed separately from the knob 40 and fixedly attached to the knob 40. However, it is desirable that the knob protrusion 50 be formed integrally with the knob 40 in order to reduce the number of parts. The knob protrusion 50 protrudes from the rear surface (vehicle front side surface) 40a of the knob 40 to the front of the vehicle (to the housing 20 side). The knob protrusion 50 is inserted through the housing 20 and protrudes to the same position as the vehicle longitudinal direction position of the slope portion 33. The front end of the knob projection 50 in the protruding direction and the lower surface in the vicinity thereof can slide on the inclined surface 33 when the knob 40 is operated. As shown in FIG. 3, the amount of lap in the vehicle longitudinal direction between the knob protrusion 50 and the slope portion 33 is such that the knob projection 50 does not get over the slope portion 33 when the knob 40 is rotated. To the extent that it is not set). The lower surface of the knob protrusion 50 is preferably a curved surface so as to come into surface contact with the inclined surface portion 33.

The key cylinder 60 is made of metal. As shown in FIG. 1, the key cylinder 60 includes an outer cylinder 61, an inner cylinder 62, and a protrusion 63.
The outer cylinder 61 is fixedly attached to the key cylinder attachment portion 42 of the knob 40.
The inner cylinder 62 is disposed inside the outer cylinder 61 in the radial direction. The inner cylinder 62 is supported so as to be rotatable in the circumferential direction with respect to the outer cylinder 61. Since the inner cylinder 62 is rotatable with respect to the outer cylinder 61, the key cylinder 60 has a play necessary for the function (a gap between the inner and outer cylinders 61, 62).

The protrusion 63 is provided on the inner cylinder 62. The protruding portion 63 protrudes forward of the inner cylinder 62 from the vehicle front side end. The protrusion 63 passes through the housing 20 and protrudes to the same position as the position of the contact portion 34 in the vehicle front-rear direction. As shown in FIG. 4, the amount of lap in the vehicle front-rear direction between the protrusion 63 and the abutment 34 is such that the protrusion 63 does not get over the abutment 34 with a normal knob operating force. To the extent that it is not set).
The protrusion 63 is provided at a position deviated from the axis of the inner cylinder 62. Therefore, when a key (not shown) is inserted into the key cylinder 60 and rotated, the vertical position of the projection 63 and the vehicle horizontal position change. As shown in FIG. 2, the protrusion 63 comes into contact with the abutment portion 34 to make the knob 40 inoperable, and the key lock position 63 a disengages from the abutment portion 34 to enable the operation of the knob 40. It is movable to the release position 63b.
When the protrusion 63 is in the key lock position 63a, the key 40 is locked and the knob 40 cannot be operated. When the protrusion 63 is in the key lock release position 63b, the key lock is released and the knob 40 is operated. can do.

The rod 70 is made of resin, for example. As shown in FIG. 7, the rod 70 moves together with the first stay 31 and moves together with the first rod 71 entering and exiting the hole 91 provided in the instrument panel 90 and the second stay 32 and moves the instrument panel 90. And a second rod 72 that goes in and out of a hole 92 provided in the.
When the first and second rods 71 and 72 enter the holes 91 and 92, the glove box 80 maintains the closed state. The first and second rods 71 and 72 are inserted into the holes 91 and 92 with respect to the glove box 80 by a return spring (not shown) disposed between the first rod 71 and the glove box 80. Always energized.
The first rod 71 extends in the left-right direction of the vehicle. The first rod 71 may be formed separately from the first stay 31 and connected to the first stay 31 and the connecting portion 31a of the first stay 31 (see FIG. 1). It may be formed integrally with the stay 31.
The second rod 72 extends in the vehicle left-right direction. The second rod 72 may be formed separately from the second stay 32 and connected to the second stay 32 by a connecting portion 32a (see FIG. 1) of the second stay 32. It may be formed integrally with the stay 32. In the illustrated example, the first and second rods 71 and 72 are formed separately from the first and second stays 31 and 32.

Here, the operation of the embodiment of the present invention will be described.
(I) When the protrusion 63 of the key cylinder 60 is in contact with the upper surface of the contact portion 34 (at the key lock position 63a), the knob protrusion 50 is not in contact with the inclined surface 33. , Above the slope portion 33. In this state, even if it is attempted to pull up the knob 40 with a normal operation force, the knob 40 cannot be pulled up (the knob 40 is fixed) because the protrusion 63 is in contact with the contact portion 34.

  When the knob 40 is forcibly pulled up with a large force exceeding the normal operating force, the abutment portion 34 (second stay 32) is deformed, and the projection 63 is not in contact with the key lock state. There is a risk that the knob 40 may be lifted off the contact portion 34. However, even when the protrusion 63 is detached from the contact portion 34, the knob protrusion 50 slides on the slope portion 33, and the stay 30 moves in the horizontal direction as shown in FIG. The rod 70 can be removed from 91 and 92 and the glove box 80 can be opened. Therefore, even if the knob 40 is forcibly pulled up with great force, the contents in the glove box 80 can be taken out from the glove box 80. Further, when the contact portion 34 (second stay 32) is not broken, a key (not shown) is inserted into the key cylinder 60, and the key cylinder 60 is rotated 90 degrees in the key lock releasing direction, whereby the protrusion 63 is formed. It is possible to return to the normal key lock release position 63b.

(Ii) When the projection 63 of the key cylinder 60 is disengaged from the abutment 34 (at the key lock release position 63b enabling the operation of the knob 40), and in the key lock release state, the knob projection 50 It is not in contact with 33 and is above the slope 33. When the knob 40 is pulled up in this state, the knob projection 50 slides on the slope portion 34 and moves the stay 33 in the horizontal direction. As a result, the rod 70 can be removed from the holes 91 and 92 of the instrument panel 90 and the glove box 80 can be opened.

Next, the operation and effect of the embodiment of the present invention will be described.
(A) The key cylinder 60 is attached to the knob 40, and the protrusion 63 of the key cylinder 60 is movable to a key lock position 63 a that makes contact with the contact portion 34 of the stay 30 and disables operation of the knob 40. Therefore, even if the knob 40 is pulled when the key is locked, the knob 40 cannot be moved relative to the housing 20. Therefore, the knob 40 can be fixed when the key is locked. Since the knob 40 is fixed, it is superior in theft compared to the conventional product and can give the user a sense of security.

(B) (b-1) A knob projection 50 that slides on the slope portion 33 of the stay 30 is provided, and the projection 63 of the key cylinder 60 is movable between a key lock position 63a and a key lock release position 63b. Therefore, the knob protrusion 50 only needs to be arranged in consideration of sliding on the slope portion 33 (it is not necessary to be arranged in consideration of locking / unlocking of the glove box 80). 60 should just be arrange | positioned only considering the lock / unlock of the glove box 80 (it is not necessary to arrange | position considering that it slides on the slope part 33). Therefore, there are few restrictions on the arrangement positions of the knob protrusion 50 and the key cylinder 60. Therefore, the amount of lap in the vehicle front-rear direction between the knob protrusion 50 and the slope portion 33 can be increased. (B-2) Since the knob protrusion 50 is provided integrally with the knob 40, unlike the key cylinder 60, the knob protrusion 50 does not have a play necessary for the function (a gap between the inner and outer cylinders).
As a result, it is possible to prevent the knob protrusion 50 from getting over the slope portion 33 (disengaged from the slope portion 33) when the knob 40 is operated when the key lock is released. The glove box 80 can be opened.

Since the slope portion 33 and the knob projection 50 are made of resin, even if the knob projection 50 slides on the slope portion 33, the knob projection 50 can be prevented from being damaged or scraped.
Even when the knob 40 is forcibly pulled up with a large force and the projection 63 gets over the contact portion 34 (the projection 63 is detached from the contact portion 34), the knob projection 50 slides on the slope portion 33. Since the glove box 80 can be opened, the contents accommodated in the glove box 80 can be taken out.
