Abstract
A vehicle door latching striker 10 has a pressed sheet metal mounting base 12 and a unitary loop formation 16 formed from metal rod with a pair of limbs 18 and 20 and a median latch bolt engaging portion 22 of substantially smaller cross-sectional area than that of the limbs.
Description
2336178 1 VEHICLE DOOR LATCHING STRIKER This invention relates to vehicle
door latching strikers. The term Z "door" is used herein to comprise not only the driver's or passenger doors 0 of the vehicle but also other body closures such as bonnets or hoods, and/or boot or trunk lids.
Latch mechanism, commonly mounted in or on the door. includes a bolt, commonly a rotating claw which coacts with and engages a striker, usually on the door post or other fixed structure surrounding the door, to selfenaaae and keep the door closed until the mechanism is released for openina. In some applications, such as a bonnet or hood, the latch mechanism is located on the fixed structure to coact with a striker carried on the door or other closure.
The object of the invention is to provide an improved stronger and more durable striker.
Accordin. to the invention there is provided a vehicle door latch' 1 ing C striker including a mounting base and a loop formation formed of a single piece of metal rod bent to shape to provide a pair of limbs whose ends are secured to the base and a median latch bolt engaging portion located clear of the base by the limbs, characterised in that at least a major part of each s'd limb includin. its said end is of substantially greater cross sectional al t 0 area than that of the bolt engaging portion.
Typically the rod is of circular cross section throughout its length 1 z although it is contemplated that other forms of section, for example oval, 1 1) might be used. and, possibly, that the section shape may vary throughout the length. for example the limb major parts might be oval to provide the extra cross section and the bolt engaging portipri might be of circular section.
The limbs may be parallel to each other or may have some other anszular relationship to each other and to the base and they may be straight or curved or otherwise angled in the longitudinal direction.
An example of the invention is now more particularly described with reference to the accompanying drawings in which:- Figure 1 is an end elevation of a latching striker and It c Figure 2 is a perspective view thereof.
The striker 10 has a pressed sheet metal mounting base 12 provided with fixing holes 14 to secure it in its position of use and a loop formation 16 formed from metal rod. in this example of circular cross section throuzhout.
Loop formation 16 comprises a pair of limbs 18, 20 whose ends are riveted into spaced locations of base 12. The unitary loop formation also includes a median latch bolt en-aging portion 22 in the form of a straight b c cross-bar Iving in a plane parallel to but spaced from plate 12 and merging at each end with a respective limb by a generally right angled bend.
The major part of each limb 18, 20 extending from its riveted connection to base 12 almost to said right angled bend is of substantially greater diameter than-that of portion 22 including, in this example. the 3 connecting bends merging with said major parts.
In the example shown the ratio of the diameters of the thicker limb parts to that of portion 22 is approximately 7A.
In the example shown said major parts of limbs 18 and 20 are bent to different respective angles so that the longitudinal axis of portion 22 1 1 1 is twisted with respect to the long ,itucUnal median axis of base 12.
The diameter of the bolt engaging portion 22 is sized to coact with a rotating claw type bolt (not shown) of coactina latching mechanism, the size of portion 22 and the bolt being sufficient for reliable and secure latch operation. The use of the increased thickness limb parts gives substantial added stren-th and durability to the striker for burst resistance in the case of accidental impact to the vehicle, and resistance to flexing and distortion during normal operation, in particular to withstand the quite high forces aenerated durina slam closin of the door.
c 9 The use of the invention enables strikers to be provided of more complex shapes, for example as shown in the accompanying drawings, to suit particular applications without loss of strength. In the example shown, if the loop formation 16 had limbs of uniform diameter throughout their lenath as in conventional striker formation, the overall diameter of the loop would be dictated by the sizing needed to match the claw or other latching bolt and this might not provide sufficient rigidity and strength, particularly where the limbs are bent as in the present example, flexure is likely to take place at the bends, indeed it could cause metal fatigue and eventual failure due to the off centre stressing of the limbs arising from the twisted formation referred to above.
1 4 The invention enables the provision of a much stronger striker without dictatina that the latch mechanism includina, the bolt must also be increased in size and, hence, cost, material usage, and need to accommodate the lar-er mechanism in the door or other associated structure.
0 The invention enables the use of special purpose strikers with otherwise standard latch mechanisms for special applications such as in vehicle bodies not having traditional B-pillar construction.
