Claims priority, application Germany April 6, 1956 7 Claims. (Cl. 292;-335) This invention is concerned with a closure fastener particularly for ladies hand bags and the like and is an vimprovement of the closure fastener which forms the While thevclosure fastener vof my Aaforesaid patent i necessitates the provision of two spring controlled closing or catch members vover the lock case or frame, the present invention is an improvement thereon in that only one closing member is required, which catches into the lock frame itself. This makes it possible, when opening the bag or similar article, to withdraw the closing member from its locking position bydepressing the catch member into the interior of the lock case, in which position it becomes and remains arrested until released again by the closing of the bag, to be sprung directly into engagement with the lock frame which forms the other part of the closure.

Fig. S a perspective view of a brief case provided with a closure fastener in accordance with Figs. 5 to 7.

Referring to the embodimentI shown in Figs. 1 to 4, the closure fastener consists of two units or mainparts, namely the closing frame 1 and the lock case or housing 2, within which the closing member and its lockingand releasing means are accommodated. The closing frame 1 may be connected in any known or convenient manner to the material'3 for instance of a ladies hand bag, a purse, a brief case, or the like.

Fixed tothe outside of the wall 4 of the lock case, which forms the lower unit in the drawing, is an angular ledge 5 which serves as a rest for the bottom plate 6 of the closing frame 1. Fitted to the inside vof the wall 4 is a leaf spring 7, as by riveting for instance, which is provided with an upstanding nose or projection 8 and,

The aforesaid and other objects of the invention are obtained in one embodiment thereofv by the closure fastener being provided with only one single closing member, for instance a latch, and a plate spring with a nose' or projection attached to it forA engagement with said at its underside, with a plate spring 9 preferably set olf at its end. The parts may be connected to one another by riveting or in any other manner. The closing member in the shape of a latch 10 is slideably arranged in the other part of the lock case 2 where it is acted upon by a compression spring 11. It is provided with two openings 12 and 13 into the rst of which, inthe closing position of the device (Fig. 2), the nose 8 of the spring plate 7 is adapted to project, while the second opening 13 serves for the passage therethrough of a bolt or latch. To free the latter from its closed position it can be retracted as by the depression of a bolt or plunger and then locked again in its retracted open position by the said nose or projection on the plate spring coming into engagement therewith. It is released again by a pressure plunger 14. This bolt or plunger 14Yis adapted to slide in a vertical guide in the centre of the upper part of the lock case 2 and is provided at its lower end with a bevel 15 by means of which it cooperates with a slanted on the plate spring when the bag is being closed. They v plate spring and the closing member are preferably ar- Y ranged in parallel relation to each other.

In another form of the Vinvention the closure fastener is provided with a spring-loaded catch in the shape of a lever which is positioned in the lock case preferably below a locking member which holds the said catch lever Vin its position of rest when the bag is closed. Whenthe bag is open and the closing member, which may be a cross pin on the movable ap, is out of engagement with parts of the closure fastener in their mutually closed posii tion.

In the accompanying drawings two embodiments of the v` invention are illustrated by way of example. In these drawings surface 16 of the opening 13 in the latch 10. Plunger 14 is headed by a cap 17; both the plunger and the cap are placed under the action of a compression spring `18 urging Fig. 1. A catch of any known or convenient type (not shown) may be provided to prevent the plunger 14 beinglung out of its guide in the lock case. Cap 17 is a sliding tit within the closing frame 1.

The aforedescribed closure fastener operates as vfollows:r In the closed position of the device (Fig. l1) the bevel 15 of plunger 14 affords suilicient freedom for the closing member or latch 1i? to allow of its entrance under v the'action of spring 11 into a cavity 19 at the inside of the closing frame 1, after the bottom plate 6 of the closing frame has, by contact with the tongue 9 of spring'7, withdrawn the nose 8 from the opening 12 of the latch 10. To open the closure fastener one has to depress the cap 17 against the action of its compression spring 18. This causes the bolt or plunger 14 to` move down into the lock case and its bevel 15 to press against the slanted edge surface 16 in the slot 13 of the latch 10, which is thereby retracted into the lock case 2 (Fig. 2).

When now the ap 3 of the` bagis lifted, the closin frame 1 moves upwards. This releases the Contact between the'parts 6 and 9 and thereby causes Ythe plate spring to lift, and its nose S to enter the opening 12 and to arrest the latch in its retracted position. The closing member or latch lil 4remains in this arrested position until, during the closing of the bag, the closing frame ll is passed over the cap 17 and the upper part of the lock case, whereby the bottom plate 6 engages the tongue 9 of spring 7 and presses it down into the position of Fig. 1, and thus withdraws the nose 8 from the opening 32 in the latch since the plunger le, after the cap i7 has been released, has been pushed up by its spring i8, whereby the latch it? has become free to be pushed by its spring ll into the cavity 19 of the closing frame il. The bag is now closed.

In the modified form of the closure fastener as shown in Figs. to 8 the closure fastener consists of two units or main parts, of which the first part 5i, forming the closing frame, may be connected to the material 3 of a bag in any known or convenient manner.

The second part consists of the lock case 61 which may be secured to the work piece as by means of the prongs 62, or in any other manner.

Slidingly provided in the lock lcase 61Y is the locking member 63. It is acted upon by a compression spring 65 which bears against a screw or post extending from the lock case and presses on a nose 64 of the locking member 63, which is thus urged into its closing position according to 1Eig. 5. i

Also provided in the lock case, below the locking member 63, is a catch lever 66 which is acted upon by a compression spring 67 tending to push the lever into the posishown in Fig. 6. This catch lever is of stepped formation and rests in yan inversely stepped cavity of the lock case 61. The first step at its operating end serves as a stop to prevent the locking member 63 from exceeding its closed position, while the second step holds it in its open position. The third step, which is the tail end of the lever, is beveled od to afford a rest on the lbottom of the lock case when the catch 66 is in its tilted position under the action of spring 67 (Fig. 6).

Part 51 of the closure fastener is recessed or cut out to the width of the locking member 63, and the recess is bridged over by the pin or stud 52 forming the closing member as shown in Fig. 7. In the closed position of the device pin 52 takes its position in the front part of the case where it is received in recesses of the side walls which are shown in broken lines in Fig. 6, and inv which it is locked by the locking member 63. Moving the said locking against the action of its spring 65 out of the closed position of Figs. 5 and 8 into the position of Figs. 6 and 7, pin 52 becomes free and the closure can be opened.

In order to close the fastener, pin 52 is moved in the direction of the lock case 61 together with the flap of the bag, whereby it presses the free end of the catch lever 66 inwardly. As soon as the catch lever liberates the nose 64 of the slide member 63, the latter is pushed by its spring 65 into the position of Fig. 5 and the closure fastener is locked again.
