LOUIS JANOIR, OF ST.-OUEN, FRANCE.
LATCH.
Application filed August 22, 1927, Serial No. 214,767, and in France August 27, 195% The present invention has :tor its object the provision ot' a latch more particularly applicable tor fastening' the doors ot motor car bodies.
'lhe latch is ot such construction that its bolt Ais constituted by a rod or lstem at right angles to the door, capable ot rotation and provided with side projections, which, upon closing ot the door, encountering abutnients carried by the keeper, pass over these abutinents, by causing the bolt to turn, and tall. back behind these abutments under the action ot a spring.
Preferably, the side projections of the bolt have the ,general shape o'l wedges, the points olf which are set in the returning direction ot the bolt and the abutinents ot the staple are constituted by wedges reversely set.
@wing to these arrai'igements, the latch in accordance with the invention ensures a closure without play, whatever 'may be the degree of wear of the meinliers in contact, the fastening ol,E "he door against Athe `fixed corresponding part being always realized by the action oi' the spring on the bolt.
Another'fiature ot the latch in accori'lanee with the .invention consists in the ari-alarenient oit the door and the fixed corresponding part, of tapered niale and len'iale ineinbers, respectively, concentric with the bol t, which lit into each other upon closing, ensuring` at the saine time the centering.
'lhe areoiniiianying drawing` illustrates, by way ot example, one of the forms oit` execu tion ot' the latch in accordance with the invention.
Fig. l is a front View of the keeper.
Fig. 2 is a longitudinal section of the latch througli an axial plane; it shows the latch before engagement.
Fig. 3 is a section similar to the preceding one, but it shows the latch after engagement.
litiga 4; .is a diagrammatic end "View ot the bolt.
The door 'l carries a casing 2 wherein is iournalled, at right angles to the door, cylindrical rod 3 constituting` the bolt. The rod 3 can rotate about its axis, but is preveiited 'from having any longitudinal movement by a suitable abutment, such as a lever t rigidly mounted on the said rod and held between the door and the casing 2. The rod 3 is brought back, in the direction ot the arrow (Fig. 3), by a spiral spring 5 (Fig.
4), or any the lever a.
Opposite the bolt, the door irainereceives the keeper (i, perforated with a circular opening on the walls' of which are distributed abutments 7, oit wedge shape having side] ,faces constitii'ted by helical inclines it, i).
The corresponding end ol the bolt 3 earries side pioiections S (Fig. et) having; a shape similar to that oit the abutinents L However, the wedges which are formed by the projections 8 are set in reverse direction to those constituting the abutnients 7, Vthat is to say their points are turned, towards the direction in which the bolt is turned by the spring- 5. The other end oli the bolt is provided with an operating. handle (not shown).
Concentrieally with its central opening, the staple is provided with a temale frusta conical bearingl portion 9 to which corresponds, on the easingl 2, a male truste-conical bearing,- portion l0. Near the end ol' this male bearingi portion, the casing transversely ont away :for giving passage to the abutments ot the keeper, upon closing oi the door.
AWhen thc door is pushed, the side projections ol the bolt come in contact with the abutinents oit the keeper. The inclines, forming the side-:faces oi" the said side projeetious and abutlnents, determine the rotin tion ot the bolt in the direction ot the arrow o (Fie: 2), during` the time the door continues its movement. At the saine time, the spring 5 is put under tension and as soon as the infojr-ictions ot the bolt have passed beyond the points ot' the abutnieiits ot the keeper, they tall back behind these abut nients and the sprinpr 5 brings hack the bolt in the direction oit the arrow Y). By pressing a gainst each other the respi-xctive bearing portions ot the casing and ot the staple. prevent rattling, owingto their tapered torni and the sung engagementellectcd by the projections 8 and the abutn'ients 7.
The returning inovenieiit ol the bolt by the springl Ii is not lin'iited in a positive manner; therefore, it stops only when the bearing portions oit the casing and olA the keeper are lirnily pressed against each other, Thus doingv away with play.
Opening ol the door is otlfeeted by turning' the handle in the direction ot the arrow a, and by pulling` the door open.
other resilient means, acting on l (l fi lll) It is obvious that the directions of rotation can be reversed according to the shape or the arrangement of the handle. Moreover, the invention is not, of course, limited to the exact details of construction described and illustrated. Thus, the male and female bearing portions of the casing and of the keeper can have another shape than that of a irustuni and can be of cylindrical, cylindro-conical, spherical or like Shapes, provided the two corresponding parte are capable of snug interfitting with each other.
I claim:
A latch 'for motor car body and other doors, 4comprising a rotating bolt subjected to the .reaction of a spring and a lixed keeper forv receiving-the said bolt, a member for anchorage on the door and provided with a conical nipple drilled in order toserve as a bearing for the front part of the bolt, a keeper for anchorage on a part fixed with respect to the door and provided with a circular recess enlarged at its front part for providing a conical surface upon which the conical nipple takes a bearing when the door is closed, radial protrudingr parts on the bolt having two faces converging in the direction .of the rotation of `the holt when the saine is acted upon by the spring, radial corresponding protruding parts provided on rhikeeper internally to the circulnr receas of the lultter, and having faces converging in :in opposite direction to the corresponding faces of the protruding parte of the bolt.
In testimony whereof I have Signed my. name to this specification.
LOUIS JANOIR.
