UNITED STATES AT TS 3 Claims, 7 Drawing Figures 2,161,519 6/1939 Loftin et a1. 292/127 3,572,790 3/1971 Kapanka 292/125 LOCK WITH A STAPLE-TYPE BOLT This invention relates to a lock with a staple-type bolt, used in particular for a front bonnet or boot lid of a vehicle.

There are used currently for closing automobile bon' nets locks which lock a closure member in the form of a staple. The latter is fixed to one of the two members which may be applied one against the other to effect the closure. The staple is arranged in such a way that just before the end of the closure movement it penetrates into the lock fitted into the opposite member.

Locks of this type are comprised of a staple immobilizing a catch or hook which is mounted so as to pivot and which is held in the closed position by a spring. The upper part of this hook is of such a shape that its contact with the bar of the staple causes by reciprocal sliding the pivoting of the hook and its retraction in relation to this staple up to the end of movement of the latter, limited by the contact of the two aforementioned members. Locks of this type have the advantage of being able to be controlled by operating a pull-handle or similar member; but they generally have the disadvantage of poor longitudinal and/or transversal retention.

This invention relates to a lock of the abovementioned type which obviates the disadvantage mentioned by ensuring longitudinal retention in the event of a shock and holding in position in all directions. It is characterized in that the hook is formed by an arm of a pivoting lever arranged in a casing which provides a guide in all directions for the staple and comprises a seating in which there slides an ejector guided parallel to the staple, springs which push this ejector towards the exterior of the seating in such a way that it is in contact with the staple support before the end of the movement of the staple towards the book so as to be locked, whereas, during the unlocking of the staple by a remote control causing the hook to pivot, the ejector raises the staple support so as to remove it from the lock and to withdraw the staple from the grip of the hook.

Other features of the invention will appear in the following description of one form of embodiment of the lock, given by way of example with reference to the attached drawings, in which:

FIG. 1 is a front view of the lock and its bolt, represented separated from one another;

FIG. 2 is a side view of the two parts in FIG. 1;

FIG. 3 shows in perspective the lock and bolt in the open position;

FIG. 4 shows in perspective the lock and bolt in the closed position;

FIG. 5 shows a section through the lock along the line V--V in FIG. 1;

FIG. 6 is a section along the line VI-VI' in FIG. 2;

FIG. 7 shows a section through the lock along the line VII-VII in FIG. 1.

Referring to FIGS. 1 and 2 there may be seen on one side a bolt 1 formed by a U-shaped staple 2 which is welded on to a rectangular plate 3 fitting for example into the striking edge of a cover or lid (not shown). The latter can pivot about a hinge parallel to the striking edge.

The lock situated below the staple is comprised of a casing 4 of cast material reinforced laterally by two ribs 5 and by two flanges 6. Each flange has an oval hole 7 enabling the lock to be fixed on to the internal wall (not shown) of the boot lid closed by the lock.

The casing 4 has a right rectangular section in its upper portion. One of its front faces, visible in FIG. 1, has at its lower part a rectangular opening 8. The opposite front face has an oblong opening 9 shown in FIGS. 2 and 7 and whose axis of symmetry is located in the center plane of FIG. 7.

On the inside of the casing 4, as shown in the FIGS. 1 and 2, there is arranged a lever 11 articulated about a pivot pin 12 whose ends are accornodated in holes in the lateral faces 13, 14, of the casing 4 and which is parallel to the upper face 10 of the casing. An arm 15 of the lever 11 is in the shape of a hook and fits into the oblong opening 9 of the casing 4; the end of the other arm 16 emerges from the casing through the rectangular opening 8.

In the upper part of the casing; 4 there is formed an oblong opening 17 for guiding the staple 2, as shown in FIGS. 5 and 7. The center axis of this opening is parallel to the pivot pin 12 of the lever l l and slightly offset in relation to the front face provided with the opening 9. The opening 17 is joined with the upper flat face 10 of the casing by a chamfering 18 which enables a good penetration of the staple into the interior of the casing.

As shown in FIGS. 5 to 7, a second part of the casing 4 constitutes the seating for at least one ejector 22. This seating is bounded by the two lateral faces l3, 14 of the casing, by a partition 19, by the front part 20 of the easing and by a bottom 21. The ejector 22 is of similar form, for example, to that of a dead bolt of a lock and has two parallel cavities 23, 24 in which there are ac comodated the upper parts of the thrust springs 25, 26, whose lower parts rest on the bottom 21 of the ejector seating. The springs 25, 26 try to push the ejector outwards.

The ejector seating has likewise two slots 27, 28 provided in the lateral faces 13, M of the casing 4 substantially in the central section of the ejector represented in FIG. 6. The ejector 22 in turn has at the lower ends of its lateral faces 29, 30, two lugs 31, 32 which slide in the two slots 27, 2h. The purpose of these lugs is to limit the travel towards the exterior of the ejector 22 and to keep it in the lock when the latter is situated in the open position in FIGS. 2 and. 3.

The hooked lever 11 is constantly subjected to the action of a spring 33 represented in FIGS. 1 and 2. This spring, of the piano wire type is wound in its central portion about the hub 11a of the lever 11', one of its ends is applied against the bottom 21 of the seating of the ejector 22, and the other end against a lug 34 of the arm 16 of the lever l 1. The spring 33 constantly pushes the arm 15 of the lever ll towards the ejector 22. The end of the arm 16 of the lever 11 has an opening 35 which allows the passage of a flexible steel cable 36 which, under the action of a control arranged at a distance acting in the direction of the arrow F,, can cause the lever 11 to rotate about its pivot pin 12 in spite of the opposing torque applied to this lever by the spring 22 The mode of operation of the lock according to the present invention is as follows:

During the closure of the boot lid represented in FIG. 2, when the striking member approaches the lock, the staple 2, shown in chain lines, engages in the guide opening 17 provided in the casing l and the lower bar of this staple slides over the back of the hook 15. This movement causes a rotation of the lever 11, the hook moving towards the left in FIG. 2, and the staple passes beneath the hook which then regains its initial position and immobilises the staple 2. During the movement of the staple the plate 3 forces the ejector 22 into its seating. The ejector then occupies the position shown in chain lines in FIG. 2 and that in FIG. 4 and its springs 25 and 26 are strongly compressed.

During the opening of the boot lid by means of a remote control exerting in the direction of the arrow F in FIG. 2; an action on the end of the arm 16 of the lever 11, the latter pivots on the pivot pin 12 and allows the unlocking of the bolt 1 by retraction of the hook 15. The ejector 22 under the pressure of the springs 25, 26 then raises the plate 3 of the staple 2 which is released and allows the free movement of the lid in the opening direction.

We claim:

1. A lock with a staple bolt, in particular for a car bonnet or boot lid, comprising in a casing a pivoting hook enabled to engage in a staple mounted on a support, said hook being formed by an arm of a lever pivoting on a pin and maintained in the locking position by a spring and enabled to be remotely controlled, an ejector sliding in a seating and guided parallel to the staple by an opening on the upper part of the casing, resilient means pushing the ejector towards ejector exterior and located in cavities of the EJECTOR and in the seating, wherein said ejector seating has lateral walls formed by the lateral walls of said casing, each of said walls of the seating having a slot substantially in its central position, and wherein said ejector has at the lower part of its lateral faces lugs which are enabled to slide in said slot and limit the travel of said ejector towards the exterior.

2. A lock with a staple bolt, according to claim 1, wherein said casing has an oblong opening in one of its faces, in which opening engages said hook-shaped lever arm when it pivots, and an opening in the face opposite the preceding one, through which emerges another arm of said lever opposite the hook-shaped one, said other arm being connected to a remote controlled transmission means.
