Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a striker mounting structure for a vehicle door lock device.

[Prior art]

As a conventional striker mounting structure for a vehicle door lock device, there is one as shown in FIGS. 6 and 7, for example.

That is, in these drawings, the retainer plate 2 is provided on the rear surface of the striker mounting portion of the vehicle body panel material (pillar) 1.
Are joined and reinforced, and penetrate through the body panel material 1 and the retainer plate 2 to form a pair of upper and lower bolt insertion holes 1a, 2
a is formed. Claw pieces 4 and 4 are extended on the upper and lower flanges of the retainer plate 2, and the tap plate 5 in which a pair of upper and lower screw holes 6 is tapped is held by the claw pieces 4 and 4 so as to adjust the position. It is arranged. The bolt insertion holes 1a, 2a and the screw hole 6 are all formed so as to match the center-to-center dimension of a pair of upper and lower bolt insertion holes 9 formed in the base portion 8 of the striker 7, and the bolt insertion hole 1
The a and 2a are formed to have a diameter larger than the shaft diameter of the bolt 10 so that the striker 7 can be adjusted in the vertical and horizontal directions. This similar structure is shown, for example, in Japanese Utility Model Publication No. 58-20051.

[Problems to be solved by the device]

However, in such a conventional structure, there are problems that the tap plate 5 is relatively large and heavy, and that the claw pieces 4, 4 that hold the tap plate 5 in a positionally adjustable manner are required. It was

The present invention has been made in view of such a conventional problem, and an object thereof is to reduce the weight and to eliminate the claw piece that holds the tap plate.

[Means for solving the problem]

In order to achieve such an object, the present invention is a vehicle door lock device in which a retainer plate is joined to the rear surface of a striker mounting portion of a vehicle body panel, and a striker for engaging and disengaging a door lock mechanism is movably attached to the retainer plate. In the striker mounting structure, the nut that is screwed to the fixing bolt of the striker is a crimping nut that can be crimped to the retainer plate, and the spacer is inserted between the locking edge of the crimping nut and the retainer plate. Is mounted so that movement can be adjusted against the frictional force of the spacer.

[Action]

When adjusting the mounting position of the striker, strike the striker in the adjustment direction without tightening the fixing bolt to the caulking nut and tighten the striking nut to the retainer plate by the appropriate frictional force of the spacer. It is possible to secure the proper mounting position by moving in the direction of adjustment together with.

In this case, since the conventional tap plate is replaced with a crimp nut, the weight is reduced. Also, since the crimping nut is held on the retainer plate by itself,
Conventional claw pieces can be eliminated.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings by attaching the same reference numerals to the same parts as those of the related art.

1 to 3, a reinforcing retainer plate 2 is joined to the rear surface of the striker mounting portion of a vehicle body panel material (pillar) 1 and penetrates through the vehicle body panel material 1 and the retainer plate 2 to form a pair of upper and lower bolts. An insertion hole 1a and a mounting hole 2b are formed.

On the other hand, a pair of upper and lower screw holes 11, 11 into which the bolt 10 for fastening and fixing the striker 7 that engages and disengages with the door lock mechanism are tapped, and caulking nuts 12 and 12 are integrally formed via the connecting piece 13. (See Fig. 4).

Each of the bolt insertion holes 1a, the mounting hole 2b, and the screw hole 11 is formed so as to match the center-to-center dimension of a pair of upper and lower bolt insertion holes 9 formed in the base portion 8 of the striker 7.

The caulking nuts 12, 12 are arranged on the rear surface side of the retainer plate 2, and a cylindrical portion 12b attached to the main body 12a inserts the mounting hole 2b into the end of the eyelet shape and locks on the surface of the retainer plate 2. Is formed with a locking edge 12c.

As shown in FIG. 5, the locking edge 12c is swaged nut 1
It is formed by inserting the second cylindrical portion 12b into the mounting hole 2b of the retainer plate 2 and then crushing the end portion with a press die 14.

In order to avoid the interference of the locking edge 12c with the vehicle body panel material 1, a recess 2c is embossed in the mounting portion of the caulking nut 12, 12 on the surface side of the retainer plate 2.

The bolt insertion hole 1a is tightened and fixed together so that the striker 7 can be vertically or horizontally adjusted in position.
The diameter of the insertion hole 2b is larger than the diameter of the cylindrical portion 12b of the caulking nut 12.

Between the locking edge 12c of the crimp nut 12 and the surface of the retainer plate 2, an annular rubber or resin spacer 15 that fits into the tubular portion 12b of the crimp nut 12 is inserted.
The caulking nuts 12 and 12 are movable and adjustable against the retainer plate 2 against an appropriate frictional force.

The door lock device having such a structure fixes the striker 7 to the body panel material 1 with the fixing bolts 10 on the vehicle body panel material 1 after the painting of the vehicle body, but at this time, the bolts 10 are fixed to the screw holes 11 of the caulking nut 12. Check the consistency between the striker 7 and the door lock mechanism (not shown) without tightening, and if it is properly aligned with the door lock mechanism, tighten the bolt 10 fully to secure the base portion 8 of the striker 7 and the tap plate 5 to each other. Can be tightened together, but if the striker 7 is not properly aligned with the door lock mechanism, tap the striker 7 lightly in the adjustment direction with the bolt 10 temporarily tightened,
The caulking nut 12 held by the retainer plate 2 by an appropriate frictional force of the spacer 15 moves in the adjusting direction together with the striker 7, and an appropriate mounting position can be secured.

As described above, according to this embodiment, the caulking nut 12 is used instead of the conventional tap plate, so that the weight can be reduced. Further, since the caulking nut 12 is held by the retainer plate 2 by itself, the conventional claw piece is eliminated.

〔effect〕

As described above, according to the present invention, the retainer plate is joined to the rear surface of the striker mounting portion of the vehicle body panel, and the striker for engaging and disengaging the door lock mechanism is movably attached to the retainer plate. In the striker mounting structure of the lock device, a nut screwed to a fixing bolt of the striker is a caulking nut that can be caulked to a retainer plate, and a spacer is inserted between the locking edge of the caulking nut and the retainer plate. Since the caulking nut is attached so that it can be moved and adjusted against the frictional force of the spacer, it is possible to reduce the weight and to eliminate the claw piece that holds the tap plate.
