Definitions
- This invention relates to latch assemblies for securing doors and other closures, particularly but not exclusively on passenger and other vehicles.
- the latch assemblies may be used for passenger doors, or for such closures as boot or trunk lids, tailgates, bonnets and the like.
- the latch assembly is usually mounted on the door or other closure to coact with and engage a striker element on the door post or other frame.
- the latch assembly may be mounted on the fixed post or other frame to coact with a striker carried on the door or other closure, one common example being a vehicle bonnet latch.
- any play between the striker and the latch assembly in the closed condition may result in unacceptable rattles and squeaks and will also cause additional wear on locating surfaces and other parts of the mechanism which will rapidly worsen the condition.
- the object of the present invention is to provide a latch assembly of simple and economical construction which is particularly effective, safe and secure in use, has good durability and resistance to wear, and which provides particularly effective and accurate positioning and retention of the striker at the closed condition in a simple manner.
- a latch assembly for operative mounting on a door or other closure or on a frame thereof for releasable engagement with a striker element of the other of the frame or closure to secure the closure in its closed condition, said assembly including a latch body having a mouth in which the striker element is received, and releasable catch mechanism automatically retaining said element at an inward closed position thereof in the mouth; characterised in that said assembly further includes a pair of spaced jaws constituting opposing side walls of the mouth, at least one said jaw being displaceable and resiliently urged to an outward position in the mouth at which the striker can enter between it and the other said jaw, inward relative movement of the striker to the closed position carrying said at least one jaw inward to be acted on by a wedging formation of the body which urge that jaw towards said other jaw for laterally gripping engagement of the striker.
- both jaws are displaceable, resiliently urged to an outward position, and carried inward to be acted on by opposing wedging formations of the body on said inward movement of the striker for said gripping engagement therewith.
- the pair of displaceable jaws are linked by a yoke at the innermost end of the mouth, said inward movement of the striker being applied through said yoke to carry both jaws inward in unison.
- the displaceable jaws and yoke may be formed as a unitary component, typically a U-section resilient plastics moulding or extrusion.
- the assembly further includes a resilient buffer within the mouth which is abutted by the striker at the closed position, the engagement of the latter with the buffer serving to carry the jaw or jaws inwards as aforesaid.
- Said buffer is preferably a body of elastomeric material but a springloaded buffer formation could be used.
- each displaceable jaw is conveniently wedge shaped with faces converging inwardly of the mouth, the laterally outer face of the respective jaw coacting with an opposing outwardly diverging face of the body, but other shapes or arrangements of jaw and opposing wedging formations may be employed.
- Latch assembly 10 has a composite latch body comprising a pressed metal outer shell 12 which includes mounting lugs 14 for securing the assembly to a closure such as' a boot lid (not shown) in conventional manner.
- the body further includes a moulded plastics body core 16 which locates and encloses catch mechanism of the assembly.
- the body defines a mouth 18 opening to its lower face as viewed in the drawing and having inwardly convergent side walls.
- the assembly coacts with a striker 20 formed of cylindrical metal bar shown only in cross section in the drawing which is mounted in conventional manner at a fixed location on the frame of the lid or tailgate opening .
- striker 20 In the fully closed condition shown in the drawing striker 20 has entered mouth 18, the outer tapered walls of the latter guiding and centering it if there should be any initial misalignment. As it approaches the closed position it will have engaged and rotated a pivoted claw 22 of the mechanism anti-clockwise as viewed in the drawing about its claw shaft 24 until a resiliently loaded latching pawl 26 pivoted within core 16 releasably engages a radial face of the claw in known manner, securing striker 20 captive in mouth 18.
- a jaw sub-assembly 28 fits into this chamber and consists of a jaw unit 30 and a buffer 32 within said unit.
- unit 30 is a unitary moulding or extrusion of durable wear resistant plastics of generally U-shaped cross section, the limbs of the U being a pair of spaced opposing jaws 34 linked by a yoke 36.
- yoke 36 defines the innermost end of mouth 18 and is spaced inwardly from the closed position of striker 20.
- Jaws 34 lie to each side of striker 20 and each jaw 34 is wedge shaped, their laterally inner faces being substantially parallel in an undeflected condition while their laterally outer faces are angled to converge inwardly of mouth 18 in the direction of yoke 36.
- the laterally outer walls defining said chamber in core 16 also converge inwardly at the same angle and sub- assembly 28 fits snugly therein.
- Buffer 32 is formed from durable elastomeric material and is shaped to fill the space between the inner parts of jaws 34 and between yoke 36 and striker 20 so that it is somewhat compressed by the latter.
- a pair of ears 40 integral with the main part of buffer 32 extend through short slots in jaws 34 and into clearance openings in core 16 to prevent displacement of buffer 32 from mouth 18.
- striker 20 In use as striker 20 becomes fully engaged in mouth 18 to be secured by the catch mechanism of the assembly 10, it compresses buffer 32 so carrying the whole jaw sub-assembly 28 inwardly engaging it more deeply in mouth 18.
- striker 20 is positively located and centred in accurate alignment with the acting parts of latch assembly 10 and without being subjected to any unbalanced forces. At the same time it is located longitudinally of mouth 18 by buffer 32 supplementing the locating effect of claw 22 and cushioning it against rattling or vibration.
- Jaw sub-assembly 28 itself has a degree of resilience which will accommodate any slight misalignments and also take up any wear which may occur.
- jaw unit 30 The components of jaw unit 30 are economical to produce and simple to assemble, no fastenings being required for their location. They are expected to be long-lasting and subjected to little wear in service though they can readily be replaced if need arises.
- latch assemblies having other forms of catch and/or locking mechanism than that described above; and/or to latch assemblies coacting with other types or forms of striker than that referred to above, e.g. strikers of wedge shape or other non-circular section.
- the jaw sub-assembly may also take different forms, for example the pair of jaws and the yoke might be separate components operatively linked together and/or the jaws themselves need not be wedge shaped, jaws having parallel inner and outer faces could be wedged towards each other to grip a striker by various forms of camming or other formations of the latch body as they are displaced inwardly of the mouth.
- the resilient buffer within the jaws might be dispensed with, e.g. the striker 20 could engage yoke 36 or its equivalent directly with resiliently outward loading, e.g. by a compression spring, applied outside the yoke, or possibly the inherent resilience of the jaw sub-assembly itself might be arranged to provide sufficient springloading for some purposes.
- jaw unit 30 may comprise a single jaw 34 coacting with a conveying wall 38 and a hook shaped yoke, and locating a buffer similar to buffer 32. This single jaw unit may be advantageous where there are limitations of space though it will not provide the self-centering action of the double jaw form.
