BY Hw HTroR/VE Y United States Patent CLOSURE FASTENER Georg Retzel, Altenmittlau, Kreis Gelnhausen, Germany, assigner to the firm Drescher & Kiefer, Inh. Georg Retzel, Altenmittlau, Kreis Gelnhausen, Germany Application May 26, 1953, Serial No. 357,481

Claims priority, application Germany November 24, 1952 9 Claims. (Cl. 292-332) This invention relates to hand bags and more especially to ladies hand bags, with particular reference to the closures thereof. Its main object is to facilitate the handling and to increase the reliability of such closures and to give the bag a better protection against pick-pocketing.

Another object of the invention is the provision of a lock or closure preferably for ladies hand bags and the closing parts of which will be arrested in the position which they occupy when the bag is opened.

A furtherobject rests in the provision of means for automatically effecting such arresting while the bag is opened, and for also automatically releasing the arrested position of the parts when the bag is being closed in order to enable the closing or catch members to move into the position ready for locking the bag.

Still another object of the invention is the provision of resiliently arranged arresting means operating at preferably right angles to the direction of movement of the closing members for arresting the closing members in the open or release position as aforesaid. j

With these and other objects in view the invention broadly consists in the provision of preferably two closing or catch' members movable in relation to each other into their bag locking position by suitably arranged spring means, and in which an additional spring member is used for automatically arresting the closing members in their relative position for opening the bag.

The invention further provides that the arresting means for securing the closing members in position are automatically controlled by the closing ap of the bag, as for instance by a member such as a catch frame attached thereto, or by one of the closing case members of the bag itself, in dependence of the bag opening or closing movement respectively. The said arresting device may comprise resiliently arranged latches, pins, pawls, noses, or other projections adapted to move at preferably right angles to the direction of movement of the closing or catch members, and to cooperate with corresponding retaining means, such as openings or recesses provided in said members. Other means serving the same purpose may, of course, be used instead. Also the additional spring member may be of any suitable shape such, for example, as a leaf spring, a spiral spring, or the like.

In a modified form of the invention the closing members may be hollow and the arresting means arranged therein so as to project from within into openings, recesses, or the like suitably provided in one of the walls of the said hollow closing members.

In the accompanying drawings two embodiments of closure fasteners according to the invention are illustrated by way of example. In these drawings:

Fig. 1 is a side elevation of one embodiment of the invention.'

Fig. 2 :is a plan view thereof.

Fig. 3,represents a. longitudinal section through the device in closed condition of the bag.

Fig. 6 is a cross section therethrough on line A-B of that figure.

Fig. 7 illustrates a modified form of they closure fastener in part-sectional side elevation in its closed postion on the line C-D of Fig. 8 as particularly suited for a bag of the closing case type.

Fig. 8 is a cross section on the line E-F of Fig. 7.

Fig. 9 represents a horizontal section on the line GH of Fig. 8, and

Fig. 10 a sectional side elevation similar to Fig. 7, but in its open position.

The closure fasteners as exemplified in Figs. 1 through 6 comprises a base case 1 and a housing or cage 2 in which the closing or catch

members

3 and 4 are arranged to slide in the direction toward and away from each other. Inserted into the ap 5 of the bag is a lock frame 6 so as to it closely over the case 1. The case is fastened to the bag by means of prongs 7 or the like, which are passed through small slits in the material and then bent over. The movement of the

closing members

3 and 4 is limited by suitably placed lugs 8 which are fixed to the lower sidev of the closing members so as to move in slots 9 in the top plate of the case 1. Provided between the

members

3 and 4 is a compression spring 10 tending to move the two members apart. One endv of the spring is located in a bore 11 of the closing member- 4 while its other end is seated on a pin 12 of the other closing member 3.

The closure fastener further comprises keeper and release means shown in the Figs. l to 6 as comprising a leaf spring 13 which may be riveted or otherwise attached to the side wall of the case 1 at the inside thereof. The said leaf spring is provided with noses or pins 14 which are adapted to pass through perforations 15 in the top of casing 1. Holes or recesses 16 are providedin each of the

closing members

3 and 4 at right angles to their direction of movement, into which the pins 14 enter when in registry with holes 16 and the leaf spring 13 moves upwardly by its own resiliency. A slot 17 inV the front wall of the casing 1 is provided'through which the end of the leaf spring 13 projects into the path of the lock frame 6 on the flap 5 of the bag when the latter is being closed whereby the spring acts as a release means for pins or noses 14 as will become more fully apparent from the subsequent description.

The closure fastener just described operates in the fol` lowing manner: When the bag is closed the frame 6 is placed over the lock case 1 approximately llush with the top plate thereof as illustrated in Figs. l to 4. .In `this closed position of the bag the frame 6 depresses the protruding end of the leaf spring 13 as is shown in Fig. 4, bending the same downwardly so that the pins 14 leave their holes 16 thereby releasingthe

closing mem bers

3 and 4. `As a result, spring 10 inside the said

meinbers

3 and 4 is released and presses the twoY closing members outwardly until the'projections 8 abut against the the ap 5 of the bag in its locked position.

To open the bag it is only necessary to press the

closing members

3 and 4 toward each other in the directionl of thearrows in Fig. 5. The

members

3 and 4 are of a length such, in the close positionV of the members the combin'edlength thereof, is' equal -to or'less than the outside lengthof the case 1, or the inside lengt-h of thelock frame 6 respectively. -T his position 'of the parts is-illusfff trated in Fig. 5, from which figure it can also 'be seen;

that the lock frame 6 can now easily be lifted over the closing members. As the lek frame 6 is moved past

members

3 and 4 it releases the leaf spring 13, which bends upwardly and causes the pins 14 to snap into the holes 16 of the

catch members

3 and 4 which, in their pushed-in position, have their holes exactly over the pins 14. As aresult', the

closing members

3 and 4 are auto! matically arrested, by control of the bag ap or the lock frame respectively, in exactly the same position into which they were brought by hand-pressure during the opening of the closure fastener.

When it is desired to close the bag, the flap 5 is moved against the'bag and the frame 6 thereby moved past the

closing members

3 and 4 over the case 1. As a result, the frame 6 engages and thus presses the end of the leaf spring 13 downwardly as already described and thereby causes the pins 14 to leave the holes 16. This, in turn, releases the closing members which now can move outwardly under the action of the compression 'spring 10 into their locking position, in which they overlie the frame 6 as` illustrated in Fig. 3. The bag is now securely closed.

The

closing members

3 and 4 are preferably made in the shape of solid blocks of rectangular cross section and rounded ends, although any other shape may be employed too if found more convenient'. All externally visible parts of the lock may be ornamented, colored, or Votherwise decorated to suit taste or convenience.

While the abovedescribed embodiment of the closure fastener is particularly suited for use on bags having closing flaps, the modification illustrated in Figs. 7 to 1G is more adapted for use with bags of the type having hinged closing frames. In this case the

closing members

18 and 19 preferably consist of elongated, box-like hollow structures of sheet material, which may be sheet metal or any composition material desired. The

members

18 and 19 are mounted on a base plate 20, which is fixed to the cross member 21 of the closing frame 22, and on which they are adapted to slide to and fro in their bag closing and opening movement respectively. The base plate is suiciently wide to overhang with one half 'of its

closing members

18, 19 the cross member 23 of the other closing frame 24. l

Attached to the under sides of the

members

18 and 19 are depending

lugs

25 and 26, which are movable in a slot 27 of the cross member 21 of the closing frame 22; The ends of slot 27 limit the movement of the

members

18, 19 by the lugs 25,v 26 coming into contact therewith. To the lug 25 is fastened a pin 28 and to the lug 26 a similar pin 29, both extending in the direction of move ment'of the closing

members

18 and 19. Arranged between the

lugs

25 and 26 and so as to be supported n the

pins

28, 29 is a compression spring 30 which tends to press the

lugs

25 and 26 and, therewith, the closing 'mem'-

bers

18 and 19 in a direction away from each other.

Fixed to the cross member 23 of the other closing frame 24, approximately opposite the

lugs

25, 26 are small brackets 31, 32 4having perforatioris 33 and 34 proyided therethrough.` Thelperforations Varedisposed to Vregister with the pins 28,- 29 on the

lugs

25 and 26. When closing the bag the external ends ofthe pins 28, 29 enter into the perforations 33 and 34 under the action of the spring and thus secure the bag in its closed position as shown vin Fig. 7.

The keeper means which, as in the example shown-in Figs. 41 to 6, serves to arrest the closure fastener .in the position which its parts occupy when the bag is Vbeing opened, consists of a substantially U-shaped plate 37 displaceable in guides 38 atriglit angles to the direction of movement of the closing

members

18 and 19. The legs 39 of the U engage, when Vthe lock is closed, the slots 40` which are provided in the side walls of the

members

18, 19. `-'Ihe U-.shaped plate 37 is under the action of a compression spring 41, the other end of which .issupported on afpin in theV opposite wall of aV fixed sleeve meliberl 42 over which the

closing membersv

18, 19 fare adapted to slide. Fastened to the U-shaped plate vr37"is further a release means in form of a vertical platef43 so as to extend with its lower portion between the

cross members

21 and 23 of the bag closing frames.

This modified form of the invention operates as follows: When the bag is closed the closing frames 22, 23 rest one against the other as shown in Fig. 8 with the closing

members

18, 19 pushed apart by the spring 30 and the

pins

28, 29 projecting with their ends into the perforations 33, 34 of the brackets 31, 32, all as illustrated inig.7.` Vthen opening the bag the closing

members

18 and 19 are pressed together by hand in the direction 'indicated by the arrows in Fig. l0. The ends of the

pins

28, 29 leave the perforations in the brackets 31, 32 and the closing frames '22, 24 springslightly open. At the Asarrie time the legs of the U-shaped plate 37 enter the slots 4), thereby arresting the closing

members

18, 19 in their mutually adjoining position as shown in Fig. l0. The bag' nowbe fgllydpellsdin "th'eopen position of the bag the vertical plate 43, or an equivalent part, occupiesa position a slight distance away from the Crossmember 21 of the closing frame 22. if, now, thebag is to be closed, the other closing frame 24 is pressed toward the frame 2v2, where' by lthe plate 43 lis'displaced inwardly so as to canse the legs 3 9 of the U-plate 37` to be withdrawn from the slo'ts 40. As a result,

members

18, 19 are' no longer arrested and are able to spring apart under the action of the suddenly released spring 30. Duringtliis movement of the

parts

18, 1,9 the

pins

2,8, 29 reenter theperforations 33, 34 of the brackets 31, 32 thereby securing the lock in its closed position.

In this' modification also the catch or closing members 1 3, 19 may Ybe given a shape to suit taste' or convenience. Atrapezoidal cross section, however, such as shown 1n the drawings, has been found very attractive and is, therefore, given preference. The ends of the closing members may be slanted, as shown, or of any other shape asdef sired.
