Description

1 2545523

  The present invention relates to a lock for the

  compartment cover of a car

  bile, this lock can be actuated in opening via a metal cable while being adapted to be able to open automatically in the event of non-function-

the latter.

  The hoods that close the engine compartment and the luggage compartment of motor cars are fitted with

  locks that can be operated remotely, via

  diary of metallic cables, using levers or

  levers arranged in the passenger compartment.

  However, with locks of this type it is necessary

  may need to provide additional opening devices

  or devices which, in the event of an action cable break-

  be able to automatically open these locks

  to prevent them from being blocked during closing.

  The object of the invention is to provide a lock which can be actuated by means of a cable and which is of a very simple construction and of safe operation, both in closing and in opening even in the event

  rupture of said actuation cable.

  The lock according to the invention comprises a lever articulated on a support frame fixed to a wall of the compartment of a car and a rod secured to the cover for closing said compartment, one arm of said lever being subjected to the return action of a spring fixed to said chassis and to the opposing action of an actuating cable which can be actuated by means of a control located inside

  of the passenger compartment of the car, said lock being characterized

  laughed at by the fact that said lever has another hook-shaped arm having one end folded substantially in an "L" shape in a development normal to the plane of the hook, said rod being provided with a substantially horizontal end which, when the the lock is

  hooked by the L-shaped end of said hook.

  To open the lock, the said cable is pulled using a control arranged in the passenger compartment, which turns the lever against the spring return action, thereby releasing the rod from the end shaped as " L "of the hook

  corresponding. In the event of a break in the cable, the lever, which is subjected to the spring return action, turns in the opposite direction to the previous one and manages, even in this case, to release the rod from the end shaped as' IL "said

  hook, so that the lock remains open.

  The following description, next to the drawings

  appended by way of nonlimiting example, will make it possible to understand how the present invention can be implemented.

  Referring to the drawings, the reference 10 designates as a whole a lock for the closing cover, not shown, of the engine compartment or of the boot.

  luggage, also not shown, of a motor car.

  The frame or trunk of the lock consists of two walls designated by 11 and 12 and assembled at their lateral tabs 13, 14 and 15, 16 The references 17 and 18 designate holes made on these same tabs for the passage of bolts , not shown, which allow

  to fix the lock 10 to a vertical wall of a compar-

  wall of a motor car, the wall 11 l has two upper legs 41 and 42 folded towards the wall 12, while the latter wall 12 in turn has a central frustoconical boss 19, and an opening

vertical 20.

  Between the walls 11 and 12 is mounted a pivot axis 21 on which is rotatably mounted a lever 22 interposed between the wall 11 and the boss 19 On the arm 23 of the lever 22 is pivotally mounted a stud 24 pierced with a through hole in which is introduced, and blocked with a locking screw 25, a metal traction cable 26 This cable 26

3 2545523

  is guided through a hole 27 made on a flat 28 which

  protrudes from tab 16 and is held taut by a cap

  chon 29 fitted on the covering sheath 30 of said cable and coming into abutment against said flat 28, The cable 26 is moreover connected to a lever or to

  a control handle, not shown, located in the

car tackle.

  The reference 31 designates a tension spring attached by one end to the arm 23 of the lever 22 and by

  the other end to the flat 32 which projects at the end

half of the leg 15.

  The other arm 33 of the lever 22 is shaped in the form of

  hook The upper end of the hook is folded up

  as in "L" following a normal development in the plane of the hook, the wings of said "L", practically orthogonal to each other and designated by 34 and 35, being clearly visible in FIG. 2 In more detail, the wing 34 has a notch 36, while the wing 35 has an edge

upper chamfers 37.

  Reference 38 designates the closure rod which is

  secured to the cover, not shown, of a trunk or the like

  timent of a motor car The rod 38 has a substantially horizontal end 39, which ends in a projection 40 of a height less than the depth of

  the notch 36 provided on the wing 34.

  When the lock 10 is closed, the lever 22 and the hook 33 are in the position shown in lines

  full in Figure 1, in balance under the anta-

  gonists of the spring 31 and of the cable 26 In this condition the end 39 of the rod 38 is hooked by the "L" end of the hook 33, and more precisely retained by the wing of said "L" end Thanks to the chamfered edge 37 of the wing 35, when the closure cover is pushed down, the end 39 of the rod 38 succeeds in engaging

below hook 33.

  To open the lock 10, simply pull the cable 26 using a lever or a joystick arranged in the passenger compartment of the car. In doing so, the lever 22 and the hook 33 rotate in direction anti-clockwise and are placed in the position indicated A and shown in broken lines in Figure 1, The end 39 of the rod 38 is thus released from the hook 33, which allows it to be lifted with the cover under the action of springs which generally push this

last to open.

  In the event that the cable 26 breaks, the spring 31 would act on the lever 22 by exerting a traction which would cause it to rotate clockwise, bringing it to the position indicated by B and shown in lines.

interrupt on figure 1.

  In this case, the "L" end of the hook 33 emerges from the end 39 of the rod 38 passing over it, also thanks to the notch 36 of the wing 34 which makes it possible to easily cross the projection 40 of this same end 39

of the stem.

  As can be seen, even in this situation the rod 38 is free to lift at the same time as the cover, thus preventing the lock from becoming blocked in

closing condition.
