Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a striker for a locking device.

[Prior Art] Conventionally, a striker of a locking device that engages with a latch in a detachable manner has a U-shaped striker body whose base end is attached to a base plate, as described in Japanese Patent Publication No. 59-46693, for example. It is fixed by heat caulking. This fixed state is the 8th
As shown in the figure, the mounting hole 10 of the base plate 101
Base end portion 1 of striker body 105 fitted in 3
Upper and lower caulking parts 109, 109 are formed on 07,
The structure is such that the base plate 101 is sandwiched between the caulked portions 109, 109, and the striker body 105 is fixed to the base plate 101.

[Problems to be solved by the invention] As described above, the base end portion 1 of the striker body 105
07 is fixed to the base plate 101 by the upper and lower caulking parts 109, 109, but when a large load F is applied to the striker body 105 due to a collision or the like, the mounting hole 103 of the base plate 101 curls upward as shown by the chain line. If the fixed part is deformed and the striker body 105 is tilted significantly,
In some cases, there was a risk that it would come off and become disengaged from the latch.

Therefore, as a means to solve the inclination of the striker body 105 and the problem of preventing it from coming off, it is possible to consider, for example, increasing the thickness of the base plate 101 to strengthen the fixed part, but this would go against the weight reduction and increase the cost. It is also undesirable in terms of appearance.

Therefore, the object of this invention is to provide a striker for a locking device in which the fixed portion can be strengthened without increasing the thickness of the base plate.

[Means for Solving the Problem] In order to achieve the above-mentioned object, this invention has an engaging part that can face the striker body in a horizontal direction and engage with the locking device, and an engaging part that can be engaged with the locking device from both ends of the engaging part. The striker body is attached to the base plate by inserting the proximal ends of the two raised parts into the pair of left and right mounting holes of the base plate and caulking them. In the striker of the locking device that is fixed, both mounting holes are formed in the base plate in an embossed area higher than the general surface that contacts the vehicle body, and a ring is formed in the mounting hole and protrudes from the periphery of the mounting hole toward the lower surface side of the base plate. A shaped protrusion and an enlarged diameter part having a larger diameter than the hole diameter of the protrusion are formed on the upper surface side of the base plate, and further, an enlarged diameter part is formed on both the upright parts of the striker body, and an upper part that covers around the mounting hole on the upper surface of the base plate is formed. At the same time as forming a caulking part, a lower caulking part is formed at the end of the base end facing the vehicle body side, protruding from the lower surface of the base plate and covering the inner and outer peripheries of the protrusion and covering the lower surface. A bulging part is formed at the proximal end to be fitted into the enlarged diameter part and continuous with the upper crimped part and has a larger shaft diameter than the upright part, and the upper and lower peripheries of the mounting hole of the base plate are sandwiched between the upper and lower crimped parts. A striker with a locking device, characterized in that the striker body is fixed to a base plate.

[Function] In the striker of such a locking device, when a load is applied above the striker body, that is, in the direction in which it is pulled out, the protrusion sandwiched between the upper and lower caulking portions acts to bite into the lower caulking portion. do. As a result, the load becomes a compressive load in the direction along the plate surface, and the upward action is minimized. As a result, the mounting hole does not curl up upwards, and the striker body does not tilt or fall out.

[Embodiment] Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 7.

In the figure, numeral 1 indicates a striker that is attached to a vehicle body 3 of an automobile. The striker 1 consists of a base plate 5 fixed to the vehicle body 3 and a striker main body 9 whose proximal end 7 is fixed to the base plate 5.The attachment part of the base plate 5 to which the striker main body 9 is fixed is as shown in FIG. It is quantitatively embossed 11. This embossing 11 has the function of ensuring both rigidity of the base plate 5, and the striker body 9 protruding from the lower surface 11b of the base plate 5.
It has a function of preventing the base end portion 7 of the vehicle body 3 from coming into contact with the vehicle body 3, and has two mounting holes 13, 13 that penetrate through the vehicle body 3.
is provided.

The mounting hole 13 includes a ring-shaped protrusion 15 that protrudes from the periphery of the mounting hole 13 toward the lower surface of the base plate 5, and an enlarged diameter portion on the upper surface of the base plate 5 that is larger in diameter than the hole diameter of the protrusion 15. D is formed continuously in a stepped cross-sectional shape.

On the other hand, the striker body 9 has a horizontal engaging portion 9a.
It is formed into a tall U-shape having a pair of upright portions 9a and 9b extending downward from both ends of the engaging portion 9a, and is configured to removably engage with a latch provided on a back door (not shown). It's getting old. The base end 7 of the striker body 9 is fixed to the protrusion 15 of the base plate 5 by caulking.

That is, as shown in FIG. 3, the base end 7 of the striker body 9 fitted into the mounting hole 13 is heated by means such as hot staking and caulked from above and below with a jig. is formed with an upper caulking part 17 that covers around the mounting hole 13 on the upper surface of the base plate 5, and a lower caulking part 17 that protrudes from the lower surface of the base plate 5 and covers the inner and outer peripheries of the protrusion 15 and covers the lower surface. There is. Further, a bulging portion B having a large shaft diameter is formed by the upright portions 9b, 9b, corresponding to the enlarged diameter portion D of the mounting hole 13 and continuous with the upper caulking portion 17.

In the striker of the locking device configured in this way, the striker 9 may be damaged by collision, etc.
That is, when the load F is applied in the direction of pulling out, the lower caulking part 17 hooks and engages with the protrusion 15, so that the peripheral edge of the attachment hole 17 does not curl upward and become deformed. Therefore, it can withstand high loads. That is, when a tensile load acts on the base end portion 7 of the striker body 19, a load acts on the base plate 5 so that the protrusion 15 is lifted upward by the lower caulking portion 17. At that time,
Since the protrusion 15 is covered by the lower caulking part 17, before the protrusion 15 is deformed to roll upward, it is compressed against the base plate 5 in the radial direction from the mounting hole 13 via the protrusion 15. Load is applied. Therefore, the mounting hole 13 is not easily rolled up and can withstand high loads.

In addition, by forming a bulging part B that fits into the enlarged diameter part D and has a larger shaft diameter than the upright part 9b on the base end part 7 that is inserted into the mounting hole 13, the upright part can be inserted through the engaging part 9a. When a lateral deflection load is applied to the base end 7 of the 9b, the base end 7 where the load is most concentrated is thicker than the other shaft parts, so it may easily break or the mounting hole 13 may be deformed. There's nothing to do. In addition, since the shaft diameter is increased only in the necessary portions, a large amount of material is not required unnecessarily, making it possible to reduce costs and weight.

Furthermore, since both base ends 7, 7 of the striker body 9 are fixed to the base plate 5, when a compressive load is applied to the base plate 5, the compressive load applied from one mounting hole 13 is transferred from the other mounting hole 13. Since the mounting hole 13 can be supported by the applied compressive load, the mounting hole 13 is effectively prevented from expanding outwardly, and the surroundings of the mounting hole 13 are reinforced by embossing, so that it cannot be deformed in other directions. Deformation can also be suppressed.

Further, since the protrusion is formed on the lower surface of the embossment, deformation of the mounting hole 13 (deformation in which the mounting hole 13 widens) is prevented, and the lower caulked portion 17 does not interfere with the vehicle body 3.

[Effects of the invention] As explained above, the striker of the locking device of this invention provides the following effects.

(1) The mounting holes do not roll up easily, so
Can withstand high loads.

(2) The proximal end, where the load is most concentrated, will not break due to the bulge.

(3) Since the compressive load acting from one mounting hole can be received by the compressive load received from the other mounting hole, deformation of the mounting hole from expanding toward the outer diameter can be prevented.

(4) Since the area around the mounting hole is reinforced with embossing, deformation can be effectively suppressed in other directions as well.
