Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a resin lock stay used for restraining a resin fuel lid, which is attached to a vehicle body to be openable and closable, in a closed state.

[Prior Art] Generally, a fuel lid of an automobile is provided with an openable fuel lid. The fuel lid includes a so-called key type in which a key cylinder is attached to the fuel lid and a so-called keyless type.

In the latter type without a key, a lock stay is provided on the back surface of the fuel lid, and the lock stay is engaged with a lock member provided on the vehicle body side to hold the fuel lid closed. The locking member is remotely operated from the inside of the vehicle to release the engagement and release the restraint of the fuel lid.

By the way, the fuel lid is generally made of a steel plate as in the case of the vehicle body, but it is considered that the fuel lid is made of resin for the purpose of reducing the weight and omitting the rust prevention treatment. Therefore, the present applicants have already filed Japanese Utility Model Application No. 61-22348.
No. 1 has applied for the invention of a keyless resin fuel lid. This is the sixth in the resin fuel lid of this earlier application.
As shown in the figure, the structure is such that the lock stay 12 is directly connected to the back surface of the fuel lid 10 without interposing a bracket.

FIG. 7 and FIG. 8 show a fuel lid 10 which the present applicants have devised when the invention of the earlier application is commercialized.
This fuel lid 10 is integrally molded into the lock stay 1
2 is formed. The lock stay 12 has a substantially U-shaped cross section except for a part around the tip end portion, and three side walls 18, 20, 22 are connected to the back surface of the fuel lid 10.

However, in the lock stay 12 having the above-described structure, the fuel lid 10 is heated during the baking of the paint and is distorted in the subsequent cooling process, and as shown in FIG. 9, a remarkable protrusion 23 protruding toward the surface side of the fuel lid 10 is formed. Was formed, and there was a problem that the appearance was significantly impaired.

Further, even if the lock stay 12 is manufactured separately and fixed to the fuel lid 10, it is preferably made of resin for the purpose of resinizing the fuel lid 10. In this case as well, painting is performed after fixing to the fuel lid 10. Therefore, the same problem as described above occurs.

[Problems to be Solved by the Invention] In view of the above, it is an object of the present invention to provide a rock stay for a fuel lid that does not form a ridge that significantly impairs the appearance of the fuel lid.

[Means for Solving the Problems] The present invention is a resin lock stay used for restraining a resin fuel lid that is attached to a vehicle body to be openable and closable in a closed state, and the lock stay is installed upright from the rear surface of the fuel lid. Has a side wall, and the side wall is connected to the back surface of the fuel lid by forming a cutout portion penetrating in the thickness direction of the side wall to divide the connection portion to provide a plurality of leg portions. It is characterized in that the lock stay is connected to the rear surface of the fuel lid by the section.

[Operation] The cooling rate is different between the fuel lid and the rock stay,
Therefore, due to the difference in contraction speed, the internal stress concentrates around the connection between the two. However, in the present invention, since the notch portion penetrating in the thickness direction of the side wall is formed at the connecting portion of the side wall of the lock stay to the rear surface of the fuel lid, and the connecting portion is divided by this, the rigidity of the connecting portion becomes low.
Therefore, as the internal stress is generated, the plurality of legs are bent in the direction perpendicular to the side wall thickness, and the internal stress generated on the back surface of the fuel lid is significantly reduced. Therefore, the rear surface of the fuel lid is not formed with ridges that impair the appearance.

[Embodiment] FIGS. 1 to 4 show a first embodiment of a rock stay for a fuel lid according to the present invention. A rock stay 30 of this embodiment is integrally molded with a fuel lid 32 by a synthetic resin.

The lock stay 30 has a generally U-shaped cross section from the back surface of the fuel lid 32, and has three side walls 34, 36, and 3.
8 stands up and the tips of these side walls 34, 36, 38 are connected to the tip wall 40. On the tip end side of the lock stay 30, a first constraining wall 42 that is coupled to the distal end wall 40, a second constraining wall 44 that is coupled to the side wall 36, and a connection that couples the first constraining wall 42 and the second constraining wall 44. A wall 46 is formed,
Both of these are also connected to the side walls 34, 38. These first restraint wall 42, second restraint wall 44, and connecting wall 46
And a space surrounded by the side walls 34 and 38 is a locking member 48.
Constitutes an entrance recess of the lock bar 50 disposed at the position.

Rectangular side cutouts 52, 54, 56 are formed in the side walls 34, 36, 38 at the connection points with the fuel lid 32, respectively. As a result, the connecting portions of the side walls 34, 36, 38 are divided into a pair of leg portions 34, respectively.
A, 34B, 36A, 36B, 38A, 38B are formed (see FIG. 2). The notches 52 and 56 formed on the side walls 34 and 38 have relatively small vertical and horizontal dimensions, but the notch 54 formed on the side wall 36 has relatively large vertical and horizontal dimensions. Is cut out to the portion of the second restraint wall 44. A pair of triangular reinforcing ribs 58, one side of which is connected to the fuel lid 32, are formed on the side wall 36 so as to oppose each other.

On the back side of the fuel lid 33, the lock stay 30
Besides, a pair of bosses 60 are integrally formed, and both ends of a hinge wire 62 bent in a U shape are locked to the bosses 60. A hinge metal fitting 64 is rotatably supported at an intermediate portion of the hinge wire rod 62.
Is locked to a quarter panel 66 which constitutes a vehicle body outer plate. As a result, the fuel rod 32 is attached to the hinge wire 6
It will be attached to the vehicle body so as to be openable and closable by using the intermediate axis of 2 as a hinge axis. Further, a leaf spring (not shown) is arranged to urge the fuel lid 32 in the opening direction.

The housing 68 of the locking member 48 has a quarter panel 66.
It is locked to the in-box box shield 70 which is coupled to. The lock bar 50, which is biased by a coil spring (not shown) and projects from the housing 68, can be pulled into the housing 68 by remote control from the inside of the vehicle.

As shown in FIG. 4, in the fuel lid 32 in which the lock stay 30 of the present embodiment is integrally formed and attached to the vehicle body, as shown in FIG. 4, the first restraint wall 42 is locked by the biasing force of the leaf spring (not shown). Abuts in a pressed state and is restrained in a closed state.

When the lock bar 50 is pulled into the housing 68 from this state, the fuel lid 32 is opened by the urging force of a leaf spring (not shown).

Further, when the fuel lid 32 is pressed in the closing direction from this state, the tip wall 40, which is an inclined surface with respect to the axis of the lock bar 50, pushes the lock bar 50 into the housing 68 against the biasing force of the coil spring (not shown). While moving. At the same time when the tip wall 40 passes through the lock bar 50, the lock bar 50 is urged by a coil spring (not shown) and enters the facing gap between the first restraint wall 42 and the second restraint wall 44,
The state shown in FIG. 4 is obtained.

The second restraint wall 44 contacts the lock bar 50 to limit the rotation angle of the fuel lid 32 in the closing direction.

By the way, the fuel lid 32 is painted in the same color as that of the vehicle body, but is heated to dry and burn the applied paint. In the cooling process after the heat treatment, the cooling rates of the fuel lid 32 and the lock stay 30 are different, and therefore the internal stress is concentrated around the connecting portion of the two because of the difference in the contraction rate. At this time, in the lock stay 12 shown in FIG. 7 described above, the rigidity around the connecting portion with the fuel lid 10 is high, so that most of the internal stress acts on the fuel lid 10 side.

On the other hand, in the lock stay 30 of this embodiment, the notch 5
Since the side walls 34, 36, 38 around the connecting portion with the fuel lid 32 have reduced rigidity due to the presence of 2, 54, 56, the side walls 34, 36, 38 in this portion are bent in the direction orthogonal to the wall thickness due to internal stress. As a result, the internal stress acting on the fuel lid 32 is greatly reduced. For this reason,
The strain generated in the fuel lid 32 is so small that it can be substantially ignored.

Particularly, in this embodiment, the side wall 36 having both ends connected to the side walls 34 and 38 and having higher rigidity than the side walls 34 and 38 is provided with the notch 54 larger than the notches 52 and 56. Therefore, the rigidity of the side walls 34, 36, 38 is made uniform, and the effect of suppressing the strain is enhanced.

Further, in the present embodiment, the notches 52, 54, 56 are formed to locally reduce the rigidity, but the reinforcing ribs 58 are formed, so that the originally required rigidity is as described above. It exceeds the lock stay 12 of FIG.

FIG. 5 shows a second embodiment of the present invention. The lock stay 30 of this embodiment is manufactured from a synthetic resin separately from the fuel lid 32, and the fuel lid 32 before painting.
It has been fixed to.

The basic shape of the lock stay 30 is the same as that of the above-mentioned embodiment, but the reinforcing rib 58 of the above-mentioned embodiment is eliminated and four leg portions 72 are integrally formed at the lower end portions of the side walls 34, 36 and 38 instead. There is. A groove 74 having both ends opened is formed in an L shape on the back surface of the leg portion 72, and the groove 74 is fitted to a protruding wall 76 formed in the fuel lid 32 so as to project in a rectangular shape with an adhesive interposed. It is getting done.

In addition, the cutouts 52 and 56 formed in the side walls 34 and 38 have arcuate bottoms, and the side walls 34 and 38 are easily elastically deformed at the portions facing each other with the cutouts 52 and 56 interposed therebetween. It is possible. As a result, the lock stay 3
0 can be engaged with the protruding wall 76 by utilizing the spring force.

[Effects of the Invention] As described above, the rock stay for a fuel lid according to the present invention has a side wall that is erected from the rear surface of the fuel lid. By forming a notch, the connecting portion is divided to provide a plurality of legs, and the lock stay is connected to the rear surface of the fuel lid by the plurality of legs, so the appearance of the fuel lid is significantly impaired. It has an excellent effect that bulges are not formed.
