PATENT OFFICE.

The present invention is a lock which is primarily used for Suitcase and toolbox is intended, such an arrangement of the intended To find parts of it which have been subjected to the rough treatment to which such locks are subjected are, resists well, and which at the same time enables the locks to be very cheap Prices to sell.

In the drawing, Fig. 1 is a front view of such a lock,
■ Fig. 2 is a longitudinal section according to χ-χ ^Λ (Fig. 1), closed castle,

Fig. 3 is a longitudinal section according to xx ¹ (Fig. 1), lock open,

i Fig. 4 is a longitudinal section through the lock housing according to xx ¹ , but with the locking lever removed,

Figure 5 is a rear view of Figure 1 showing the shape and interaction the most important parts are shown,

6 shows a cross section according to yy ¹ (FIG. 1), with the view of the retaining bolt of the locking lever,

Fig. 7 is a cross-section according to ^ - ^ ¹ (Fig. 1), which shows the locking lever and locking plate in the closed state,

8, finally, a cross section according to xx ¹ , the locking lever in the open state and the locking plate withdrawn.

The lock consists of a housing A, which is provided on its edge with holes for attachment to the case or the like, and the front wall of which is removed almost over its entire length, while a large part is also missing on one of the side walls. In this opening of the closing lever C is mounted, which rests at one end on C ¹ on a rotary or base and by a leaf spring D, the free end between two fixed in the housing A pins E and E ^J passes (in the Schlufsstellung Figure . 2) is held and pressed onto its support point, so that it is effectively prevented from rattling in its support.

In this way, as shown in FIG. 3, the locking lever can make an outward swinging movement. The free end is provided with a spring lock F , which can be withdrawn by means of the keyhole F ^{1 using an ordinary key.}

The locking lever has projections G and G ¹ which engage in recesses in the locking plate attached to the case or box lid, while the nose J ^{1 of} the locking plate descends on the rear side of the housing when the lid is closed (see Figs. 5, 6 and 7). Before this part of the nose of the locking plate can enter the lock housing, the locking lever must make an outward swinging movement (Figs. 3 and 8). However, since the spring D causes the locking lever to move back into the closed position, it must be removed from the retaining bolt K, which is shown in FIGS. 3, 4, 5, 6 and 8, to

required time are held, the head of this bolt is pushed up behind the locking lever by the spring L , up to a small projection M of the locking lever, which is used to limit the stroke of this bolt.

It is clear that when the case lid is closed, the lock parts automatically assume the positions corresponding to the closed position, namely in that the nose J ¹ of the locking plate J on the rear side of the housing comes down until it hits the head of the retaining bolt K and descends below it the lower edge of the locking lever presses, so that the action of the spring D causes the locking lever to swing instantly into the housing and the projections G and G ¹ enter the recesses H and H ¹ , while the spring latch F snaps behind the inner edge of the front wall of the housing.

When Oeffhen the latch of the spring latch slides first by application of the key from its engagement behind the housing wall shown, of the closing lever is preferred in the in FIGS. 3 and 8 illustrated position, whereby the projections G and ^G] besides engagement with the Scbliefsplatte J come and allow the same free movement when lifting the case lid, with which movement simultaneously the head of the retaining bolt is released and driven by its spring, steps behind the locking lever. This prevents the latter from returning to the closing position

if the lid is not closed.

Claims (2)

Patent Claims: ι. A castle, characterized by the fact that a locking lever forming part (C) of the front wall of the lock case (A) is rotatably mounted at one end and is held in the key position at the other end with a spring-loaded latch bolt (F), which can be withdrawn by means of a key, which key position is also held by a Spring (D) is effected while the locking plate (J) penetrating perpendicular to the direction of oscillation of the locking lever is gripped and held by nose-like projections (GG ¹ ) seated on the former and engaging in recesses (H Η ^λ ) of the locking plate. 2. A castle of the under j. claimed type, in which the locking lever is prevented from snapping in when the locking plate is not in the lock case, by the fact that a spring- pushed locking pin (K) , which is mounted in the direction of movement of the lock plate in the lock case, springs forward when the lock lever is opened and counteracts it the action of the spring (D), am. prevents snapping until the striker plate inserted into the lock depresses its head and thus releases the lock lever.
