Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to an improvement of the accessory storage lock structure provided in the instrument panel of an automobile.

(Prior art) Automobiles are equipped with accessory compartments in the instrument panel and other parts of the vehicle interior, and the accessory compartment is formed by forming a recess in a vehicle body member such as the instrument panel, and closing the opening with a lid. In some cases, the lid itself is formed into a box shape and is embedded in a vehicle body member so as to be openable and closable, but in either case, a locking device for locking the lid to the vehicle body member is provided. (For example, Japanese Utility Model Application Publication No. 54-74699) The above-mentioned conventional accessory case is designed to protect against external forces received by the instrument panel, such as when a person's forehead hits the instrument panel in a car collision. When this happens to the accessory case, the surrounding parts of the locking device consisting of the engagement of the hook and the striker push the hook down and remove it from the striker, or the striker springs up due to the reaction of the collision, and the lock is released and the lid is opened. A problem arose.

(Purpose of the invention) This invention was made to solve the above-mentioned conventional problems.When an external force is applied from outside the accessory case due to a collision, etc., the lock is released and the lid opens. The object of the present invention is to provide a lock structure for an automobile accessory case, which prevents the above-mentioned problems.

(Structure of the device) The present invention to achieve the above object is to provide an accessory case formed in either a vehicle body member such as an instrument panel or a lid provided in an opening of the vehicle body member. A striker protruding from the lid is attached, and a hook having an upwardly bent engagement portion that engages and disengages the striker is attached to a base member made of a rigid body attached to the lid, and is rotatable in the vertical direction. The hook is pivotally supported in an upwardly biased state, and when the hook is engaged with the striker by force, the hook covers the upper part of the engaging part, and the tip of the engaging part is brought into contact with the back surface. This is an automobile accessory case lock structure in which a cover part is integrally formed with the base member.

(Example) Hereinafter, the present invention will be explained in detail based on the drawings illustrating the embodiment.

FIRST EMBODIMENT In FIGS. 1 to 4, reference numeral 1 denotes an instrument panel (vehicle body member), and an accessory compartment 2 is provided on the left side of the lower front part of the vehicle interior.

Reference numeral 3 denotes a lid which closes the accessory case 2.A lid inner 3a and a lid outer 3b are combined to form a space therebetween, and a hinge (not shown) is provided near the lower end. It can be opened as shown, and when closed, the top center part is locked.

4 is a striker, which is made by bending a wire into a shape, and its upper end is attached to a horizontally long striker frame 4.
a and attach the striker frame 4 to the upper side of the opening of the accessory compartment 2 of the instrument panel 1.
When the lid 3 is closed, the striker 4 protrudes diagonally downward toward the lid 3. When the lid 3 is closed, the striker 4 is inserted into the striker window 5 opened at the top of the lid inner 3a, and is inserted into the upper part of the lid outer 3b. It is configured to protrude into a concave portion 6 formed in the center.

Reference numeral 7 denotes a base member, which is a frame-shaped member made of a rigid body made of die-cast alloy, and has a cover part 1 on the top.
1 is integrally extended and installed in a recess 6 of the lid 3.

Reference numeral 8 denotes a hook, which has an upwardly bent engaging portion 8a at its tip, and whose rear end is pivotally supported 9 on a base member 7, and a torsion coil spring 10 is attached to this pivot support. Pushing the engaging portion 8a upward,
The upper end of the engaging portion 8a abuts the back surface of the cover portion 11, and the cover portion 11 covers the upper portion of the hook 8.

The back part 8b of this engaging part 8a is formed in a curved shape, and when the lid 3 is closed, the back part 8b comes into contact with the tip of the striker 4 entering from the striker window 5 in an inclined state, so that the hook 8 is attached to the pivot support 9. When the hook 8 is pressed down against the torsion coil spring 10 and the upper end of the engaging portion 8a passes the striker 4, the hook 8 is pushed down against the torsion coil spring 10 again.
The repulsive force causes the inner side of the engaging portion 8a to engage with the striker 4, as shown in FIG. 2, thereby locking the lid 3 in the closed state.

Reference numeral 12 denotes an operation member, which is attached to the base member 7 so as to be supported on the outside of a hook 8 coaxially with the shaft support 9 so as to close the upper half of the opening of the recessed part 6. An operating part 12a is provided which protrudes above the hook 8 and whose lower surface abuts the upper surface of the hook 8. When the lower end is pulled in the direction of the arrow P in FIG.
As shown in the figure, the action part 12a rotates the hook 8 downward about the shaft support 9, so that the engaging part 8
A is lowered and removed from the striker 4, the lock is released, the lid 3 is opened, and the accessory case 2 is opened.

The feature of the present invention described above is that the cover part 11 covers the top of the engaging part 8a of the hook, and the tip of the engaging part 8a is in contact with the back surface of the cover part 11. According to the structure, the engagement state between the lid 3 and the engaging part 8a is such that it cannot be disengaged as long as the tip of the engaging part 8a is in contact with the back surface of the cover part 11.

The state of contact between the tip of the engaging portion 8a and the back surface of the cover portion 11 is such that even if the cover portion 11 is subjected to a pressing force or vibration within a range not exceeding the limit due to a collision, etc., the base member integrated with the cover portion 11 Since the hook 8 is pivotally supported 9 on the lid 3 and combined together, the cover part 11 and the engaging part 8a are pushed down and vibrated as one, and the engaged state is maintained. It is possible to prevent the opening of the door.

In this regard, in the conventional one shown in FIG. 7, the cover part 11' does not cover the engaging part 8a', and the upper end of the engaging part 8a' abuts the end surface of the cover part 11'. Therefore, the instrument panel 1 is pushed down due to a collision, etc., and the lid inner 3a' is pushed in the direction of the F1 arrow, pushing the upper end of the engaging portion 8a' down in the direction of the F2 arrow, and the engagement with the striker 4' is disabled. Striker 4' due to dislodgement or reaction from collision.
In some cases, the lid 3 would open due to the lid 3 jumping up and coming off the engaging portion 8a'.

Second Embodiment FIG. 5 is a sectional view of a main part showing another embodiment, in which a protrusion 11a is provided on the back surface of the cover part 11,
The tip of the engaging portion 8a of the hook 8 is brought into contact with this protrusion 11a. According to this configuration, the striker 4 is pulled in the direction of the arrow F3 by the shock when the instrument panel 1 is pushed down during a collision. There may be cases, but in this case, striker 4
is engaged between the tip of the engaging portion 8a and the protrusion 11a,
The tensile force of the striker 4 is transferred to the hook 8 and the cover part 11.
This prevents the striker 4 from escaping, thereby preventing it from becoming unlocked.

Third Embodiment FIG. 6 is a sectional view of a main part showing still another embodiment, in which a stepped portion 11 is attached to the front end of the back surface of the cover portion 11.
b is provided, and the tip of the engaging portion 8a is connected to this stepped portion 11b.
As in the case of the second embodiment described above, the striker 4 is brought into contact with the F4 at the time of a collision.
When the striker 4 is pulled in the direction of the arrow, the tip of the engaging portion 8a is pressed against the stepped portion 11b, and the hook 8 and cover portion 11 bear the tensile force of the striker 4. This prevents the lock from escaping and prevents the lock from coming off as in the second embodiment.

In both the second and third embodiments, the striker 4 has its hook 8 pushed down by an external force at the time of a collision.
As in the case of the first embodiment, the cover part 11 prevents the cover part 11 from jumping up due to an impact.

(Effects of the invention) According to the automobile accessory compartment lock structure of the invention described above, the top of the hook in which the striker and the hook are engaged is covered with a cover part that is integrated with the base member made of a rigid body to which the hook is attached. By having a structure in which the tip of the engaging part of the hook is in contact with the back surface of this cover part, the cover part absorbs a certain range of external force that is mainly applied from above and is pushed down in the event of a collision, and directly applies it to the hook. In addition, even if the striker jumps up due to an impact, the cover part will catch it, and the cover part and the end of the hook will be in contact with each other and closed, so the lock will not come off. It is possible to prevent the opening of the opening.
