  ROCKER LOCK, ESPECIALLY FOR LUGGAGE.

  The invention relates to a lock comprising a rocker pivoting on a base, in which the rocker carries a key-operated rotary barrel for locking in the closed position, the rocker further carrying a bolt cooperating with a strike of

  the mobile part to be locked, elastic means being

  seen to keep the rocker in open and closed positions.

  Such a toggle lock is known from French Patent No. 82.00341 published under No. 2519527. In this prior patent,

  locking of the rocker is obtained by rotating a half

  turn of the barrel of which an eccentric abuts on a part

  of the base, in the locking position.

  This known lock, which is very simple and

  high robustness, however, has the disadvantage of

  rotate 180 for locking and unlocking;

  in addition, the state of the lock is not visible.

  The present invention aims to provide a new lock of the above type in which the locking and unlocking is

  by simple rotations of a predetermined angle, and in which

  the state of the lock is visible by the position of the barrel.

  For this purpose, the lock according to the invention is characterized by the

  that the barrel is finished, at its opposite end to the

  key, by a flattened extension, the said extension

  low clearance in a fixed coaxial cylindrical jacket

  a diametrical slit wider than the thickness of the

says extension.

  When the narrowing is not aligned with the diametral slot, the rocker is locked by the fact that the extension can not tilt relative to the shirt. When the narrowing is

  aligned with the diametrical slot, on the contrary, the rocker is

Berea.

  Preferably, the angle between the unlocking position of the

  rillet and lock position is 90 ', each of these

  positions allowing, in known manner, the extraction of the key.

  The invention will be well understood on reading the following description.

  FIG. 1 is a side elevational view of a lock according to an exemplary embodiment of the invention, in a closed position, FIG. 2 is a view from above of FIG. lock of Figure 1, in the locked position; - Figure 3 is a sectional view along the line III-III of Figure 1, for the locking position;

  FIG. 4 is similar to FIG. 3 for the position of

  locking; FIG. 5 is a side elevational view, partially cut away, of the lock in the open position, and FIG. 6 is a sectional view along the line VI-VI of FIG.

figure 1.

  The lock comprises a rocker 1 pivoting on a base 2 around

  an axis 3 of the base. The latch 1 carries a bolt 4 which, in

  lock, is housed in the keeper 5 secured to the cou-

circle of luggage to be closed.

  The rocker 1 carries a barrel 6 with a key channel 7 and finished

  by a flattened extension 8 in the form of a screwdriver. The extension

  8, in the closed position, can rotate about its axis, when the cylinder 6 rotates in a coaxial cylindrical liner 9 of the base 2, with a reduced clearance. The liner 9 has a diametrical slot 10 of width greater than that of the extension 8. In the locking position (FIG. 3), the latch 2 can not pivot about the axis 3 because of the coaxiality of the narrow portion of the liner. The latch 5 is kept trapped by the latch 4. In the unlocked position (FIGS. 4 and 5), the screwdriver 8, aligned with the slot 10, allows the latch 2 to be tilted according to FIG. the arrow F and the release of the

strike 5.

  To maintain the rocker 1 stably in its two posi-

  tions, a transverse slide 11, biased by a spring 12, is housed in the base 2 and its conical free end 13 cooperates,

  in the closed position, with a transverse hole 14 of the bottom

  1. In the open position of the rocker, the conical end 13 of the slide 11 bears on the edge 15 of the rocker 1

(Figure 5).

Claims (3)

CLAIMS.   1.- Lock comprising a rocker pivoting on a base, wherein the rocker carries a rotary cylinder key-controlled for locking in the closed position, the rocker carrying in   in addition to a bolt cooperating with a plug of the movable part with   rusting, elastic means being provided for holding the rocker in the open and closed positions, characterized in that the barrel (6) is terminated, at its end opposite the key inlet (7), by a flattened extension (8), said extension (8) pivoting with a small clearance in a fixed coaxial cylindrical jacket (9) having a diametrical slot (10) of width greater than   the thickness of said extension (8).   2. Lock according to claim 1, characterized in that the angle between the unlocking position of the barrel (6) and the locking position is 90, each of its positions.   allowing, in known manner, the extraction of the key.   3. Lock according to one of claims 1 and 2, characterized   in that a transverse slide (11), recalled by a res-   fate (12) and housed in the base (2) cooperates by its end co-   nique (13) with a transverse hole (14) of the rocker (1) in the closed position of the rocker (1), and with the ridge (15) of   said latch (1) in the open position thereof.
