Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hinge device for a lid that opens and closes an accessory storage opening provided on an instrument panel side in an automobile interior.
[0002]
[Prior art]
With regard to the lid for opening and closing the accessory storage opening provided on the instrument panel side, it is necessary to maintain the closed state as it is without accidentally opening it, particularly in the event of a car collision. . This is because an occupant is injured by the lid that is accidentally opened, and the stored items are scattered outside.
[0003]
For this reason, for example, countermeasures shown in Japanese Utility Model Laid-Open No. 1-138071 and Japanese Patent Laid-Open No. 7-179162 have been proposed.
[0004]
The former measure is based on the assumption of a push-open type lid, and separately from the normal locking means, a weight member urged in a predetermined direction by spring pressure on the accessory storage side of the instrument panel, and the weight member In the event of an automobile collision, an inertial force acts on the push-open type lid so that the lid rotates in the unlocking direction. However, the action of the weight member and the stopper member prevents the lid from being accidentally opened by preventing the lid from rotating in the unlocking direction.
[0005]
Also, the latter measure is based on the assumption that the glove box is equipped with a thin, stress-concentrated portion that can be broken on both sides of the glove box. In the case of a collision, the stress concentration portion is broken to alleviate the impact on the occupant's knee, and at the same time, the glove box is prevented from being accidentally opened.
[0006]
[Problems to be solved by the invention]
However, with such conventional measures, it is possible to keep the lid and glove box closed in the event of a car collision, but the former is a dedicated device, apart from the locking means. Since the restriction means must be newly provided, the cost is naturally increased, and the presence of the restriction means may limit the space on the accessory storage port side. In the latter case, the stress concentration part provided on both side walls of the glove box is broken in the event of a car crash. Depending on the degree of breakage, the contents in the glove box may be scattered outside. I had a fear of it.
[0007]
For this reason, there is a great demand in the field for the emergence of a new device that can reliably keep the lid closed in a very simple manner even if the normal locking means cannot function. .
[0008]
[Means for Solving the Problems]
The present invention has been developed to meet such a demand, and the invention according to claim 1 is a hinge device for a lid for opening and closing an accessory storage port in an automobile interior, and is a hinge base fixed to the vehicle body side. And a hinge arm fixed to the hinge base and fixed to the hinge base so that the hinge base is positioned at the front of the vehicle body, the hinge arm extends to the rear of the vehicle body, and the lid is opened. When the hinge arm is separated from the hinge base and the lid is closed, the hinge arm approaches the hinge base, and an opening is provided in either the hinge base or the hinge arm, and the width of the opening is determined on the other side. In addition, a configuration is adopted in which a tapered side edge extending from a narrow width to a wide width is provided so that when an external force in front of the vehicle body is applied to the lid, the tapered edge enters the opening .
[0010]
Therefore, in the invention described in claim 1, for example, in the event of a car collision, a large external force is applied to the front of the vehicle body such that the head of the occupant hits the lid and the locking means is damaged. Even if the taper side edge provided on the other side enters into the opening provided on either the hinge base or the hinge arm using a narrow width, the wedge effect is applied to the edge of the opening. Since it bites with it, it is possible to guarantee a reliable and strong restraint state of the hinge arm on the hinge base side. In addition, the hinge mechanism itself is modified to prevent the lid from being opened, which is economically inexpensive.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on a preferred embodiment shown in the drawings. A hinge device according to the embodiment includes a small article storage port provided on the upper side of an instrument panel P as shown in FIG. It was developed for a lid L that opens and closes H, and includes a hinge base 1 made of a metal plate that is fixed to the vehicle body panel side, and a hinge arm 2 made of a metal plate that fixes the lid L.
[0013]
As shown in FIG. 2, the hinge base 1 is composed of a bent upper portion 1A, an intermediate portion 1B, and a lower portion 1C. The hinge base 1 has a substantially rectangular shape that extends laterally at the center of the upper portion 1A and the intermediate portion 1B. Opening 3 is provided , two cylindrical shaft support portions 4 and two horizontal L-shaped stopper pieces 5 are provided on the upper edge of the upper portion 1A, and a plurality of attachments are provided on the entire outer periphery. The hole 6 is formed.
[0014]
As shown in the figure, the hinge arm 2 comprises a bent vertical portion 2A, a horizontal portion 2B, and an extended portion 2C. Three cylindrical shaft support portions 7 and the stopper piece 5 are attached to the upper end edge of the vertical portion 2A. In addition to this, the two receiving grooves 8 to be engaged are provided, but in addition to this, the total width W2 of the vertical portion 2A is larger than the width W1 of the opening 3 of the hinge base 1. The horizontal width W3 excluding the base end near the vertical portion 2A is set equal to or slightly larger than the horizontal width W1 of the opening 3 of the hinge base 1 for the horizontal portion 2B. In addition, a pair of tapered side edges 9 connected to the narrow lateral width W2 of the vertical portion 2A and the wide lateral width W3 of the horizontal portion 2B are positively provided on the base end portion near the vertical portion 2A. . The extended portion 2C extends in a narrow state from the center of the free end of the horizontal portion 2B, and is provided with a configuration that can fix the front end of the lid L from the back side.
[0015]
Further, in the present embodiment, three beads 10 are formed across the vertical portion 2A and the horizontal portion 2B to increase the rigidity of the portions 2A and 2B, and at both side edges of the vertical portion 2A. A pair of notches 11 that promote deformation of the vertical portion 2A are formed, but at least the beads 10 on both sides are set so that the ends thereof are positioned at the same level as the notches 11. .
[0016]
Therefore, if the hinge shaft 12 is inserted into the cylindrical shaft support portions 4 and 7 provided alternately, as shown in FIG. 3, the hinge base 1 and the hinge arm 2 are perpendicular to the upper portion 1A. In the present embodiment, a torsion coil spring 13 is attached to the hinge shaft 12 and the torsion coil spring 13 spring is connected. A configuration is also employed in which the hinge arm 2 is constantly urged in a direction away from the hinge base 1 by pressure.
[0017]
Therefore, as shown in FIG. 4, a state in which the lid L is fixed to the horizontal part 2B and the extension part 2C of the hinge arm 2 is obtained, and the corresponding parts of the vehicle body panel 14 in which the hinge base 1 is located inside the instrument panel P are obtained. If it is fixed to the boss 15 via the mounting hole 6 and the screw 16, the hinge base 1 is positioned in the front of the vehicle body and the hinge arm 2 extends in the rear of the vehicle body, and the lid L is on the accessory storage port H side. Can be opened and closed. In this state, a space S that allows the tapered side edge 9 of the horizontal portion 2B to enter is positively defined between the back surface of the opening 3 of the hinge base 1 and the surface of the vehicle body panel 14. The Rukoto.
[0018]
Therefore, as shown in the figure, when the lid L is rotated in the closing direction against the spring pressure of the torsion coil spring 13, the closing of the lid L by the action of the lock claw 17 and the striker 18 constituting the locking means. The state is maintained, but when the lid L is closed, the vertical portion 2A of the hinge arm 2 is close to the upper portion 1A of the hinge base 1 and the opening 3. On the contrary, as shown in FIG. 5, when the lock by the locking means is released, the lid L is a spring of the torsion coil spring 13 until the receiving groove 8 of the hinge arm 2 is engaged with the stopper piece 5 of the hinge base 1. It is automatically rotated in the opening direction by pressure so that small items can be taken in and out of the small item storage opening H. When the lid L is opened, the vertical portion 2A of the hinge arm 2 is the upper portion of the hinge base 1. 1A and the opening 3 are separated.
[0019]
In the closed state of the lid L, when a passenger's head hits the lid L due to, for example, a collision of the vehicle, and a large external force is applied to the lid L so that the locking means is damaged. 6 and 7, this time, the tapered side edge 9 of the horizontal portion 2B of the hinge arm 2 enters the opening 3 of the hinge base 1 using the narrow width W2 of the vertical portion 2A. Thus, since the both side edges 3a of the opening 3 bite in with a wedge effect, the hinge arm 2 is securely and firmly restrained on the hinge base 1 side.
[0020]
When the taper side edge 9 of the horizontal portion 2B enters the opening 3, the deformation of the vertical portion 2A is urged by the action of the notch 11 of the vertical portion 2A described above. Even if the upper portion 1A of the base 1 is present, there is no obstacle, and the presence of the space S never prevents the tapered side edge 9 from entering.
[0021]
Therefore, even if the lid L is urged in the opening direction via the hinge arm 2, the lid L can be reliably prevented from being opened accidentally, so there is a concern that the occupant may be injured or the stored items will be scattered outside. Disappear. Moreover, under the present embodiment, unlike the conventional one, it is intended to achieve the intended purpose with a very simple method of modifying the hinge mechanism itself. It will be economically cheap.
[0022]
In the above-described embodiment, the opening 3 is provided on the hinge base 1 side, and the tapered side edge 9 is provided on the hinge arm 2 side so as to enter and bite into the opening 3. However, the present invention is not limited to this, and the same result can be obtained even if the tapered side edge 9 is provided on the hinge base 1 side and the opening 3 is provided on the hinge arm 2 side under the same principle. Needless to say.
[0023]
【The invention's effect】
As described above, according to the present invention, by adopting the above-described configuration, under the first aspect, for example, in the case of an automobile collision, the head of the occupant hits the lid and the locking means is damaged to the lid. Even if a large external force is applied to the opening, the taper side edge provided on the other side enters the opening provided on either the hinge base or the hinge arm using a narrow width, and the opening Since the edge bites into the edge with a wedge effect, it is possible to guarantee a reliable and strong restrained state of the hinge arm on the hinge base side. In addition, the hinge mechanism itself is modified to prevent the lid from being opened, which is economically inexpensive.
