AGREES WITH EXIT 1 064 270 (B 47909 HI / 44a)

The present invention relates to a clip watch strap with two lugs on the watch hinged clamp legs, which are located under We ^ put a spring around your arm.

It is known in clip watch straps to fix the clip legs in the closed position Latches movable lengthways under spring action or the joint end parts of the clamp legs themselves in the To arrange lugs of the clock longitudinally movable and by means of opposing in the direction of movement Bring locking parts into engagement. In the known devices, the relevant But parts are moved lengthways by hand and against the action of a spring. Since only one hand is free for this only one leg at a time can be secured or released and therefore the connection is and taking off the clip watch straps awkward. The same also applies to other embodiments which the clamp legs are only pivotably mounted and in the same transverse to their longitudinal direction are arranged vertically or horizontally under spring action outwardly pivotable locking parts with Counter-locking parts of the clock lugs cooperate in the open and / or closed position. Through the present Invention, the deficiencies outlined are remedied.

According to the invention, the hinge parts of the clamp legs are short by means of their hinge pins The elongated holes of the watch case joints can be moved lengthways, and those on the hinge pin and guide pin at the same time mounted pivot spring of the clamp legs is supported by an arm located approximately at right angles to the guide direction on the watch case, whereby the joint part in the watch case is automatically pushed outwards and with one after outwardly directed detent from an inwardly directed detent of the watch housing abutment when swiveled in or out Position of the clamp leg is under or over grasped.

In the new construction described, it is necessary to determine the clamp legs in the closed position just wrapping the same around the arm, because it automatically stops the rest of the joint part the rest of the watch jumps. Both clamp legs can be used to release this locked position by grasping with two fingers of one hand behind their joint parts with the same against the effect their spring pushed back at the same time in the watch lugs and thereby their rest under the rest of the Watch lugs pulled away and the clip legs swung open and the clip watch strap simple be lifted off the arm. With this open position of the clamp legs and release of the finger pressure slide the joint parts of the clamp legs clamp watch arm and

under the action of its spring again to the outside, and its detent now engages over the counter-detent of the watch case lugs. This keeps the clip legs in the open position and the clip watch strap can easily be placed on the arm. When closing the clamp legs slide due to their resilient longitudinal guidance in the clock lugs the mutual notches of the one on top of the other in the other position.

In the drawing, an example embodiment of the subject matter of the invention is shown in six figures shown. It shows

Fig. 1 the clip watch strap in the closed state in a side view with a vertical longitudinal section through the connection point of the right clamp leg,

Fig. 2 the connection point in the same view with the clamp leg open,

The clip watch strap has two clip legs A which are pivotably connected to a watch case B. The clamp legs A are each formed from a U-shaped flat wire bracket 1, each of which is closed by a U-shaped joint part 2 at its open end. The joint parts 2, which

have the shape of downwardly open boxes, comprise the watch lugs 3 fixedly arranged on the watch case B. The hinge parts 2 are closed at the bottom by a bottom 4, on the top of which a box 5 is formed by two longitudinal walls 5 'and a transverse wall 5 ". The bottom 4 is inserted on the one hand with a tongue 6 in a slot 2 'in the transverse wall 2''of the joint part 2 and, on the other hand, is suspended from an axle pin 7 by means of bores in its side walls 5'. This axle pin 7 extends further through elongated holes in the longitudinal walls of the watch case 3 and through bores in the longitudinal legs of the joint part 2 and thus connects these parts to one another in a pivotable manner. Between the side walls 5 'of the box 5, a lever arm 8 is pivotably arranged on the axle pin 7 and has a U-shaped cross section. Between its side walls 8 ', a spreader spring 9 with its winding part is mounted on the axle pin 7, one arm 9' of which is supported against the bottom 8 "of the lever arm 8 and this on a protruding part 10 of the watch case wall 10 ', while the other spring arm 9 "is supported on the floor 4. Since the axle pin 7 is movably mounted in short elongated holes 11 in the longitudinal walls of the housing abutment 3, the joint piece 2 and the case 5 can also be moved lengthways with its base 4 and abut the watch case by the lever arm 8, which is supported on the projection 10 of the watch case wall under spring pressure 3 can be pushed outwards. The end wall 5 ″ of the box 5 protrudes outward at the top with a locking edge 5 '″. The watch case lugs 3 terminate in an inwardly and outwardly protruding locking strip 12, the outwardly protruding part being covered by the cover 13 of the joint piece 2.

• When the clamp legs A are in the closed position, the parts of their connecting hinge assume the position shown in Fig. 1 with respect to one another. The clamp leg is pivoted inward by the arm 9 ″ of the spring 9. The lever arm 8 is supported on the protruding part 10 of the watch case wall 10 ′ by the other arm 9 ′ of the spring 9, and the joint part 2 together with the case 5 and its base 4 with the hinge pin 7 in the slots 11 of the clock lugs 3 pushed outwards, the transverse wall 5 "of the box 5 with its outwardly projecting locking edge 5 '" grips the locking strip 12 of the clock case 3 at its inwardly directed part and thus the clip leg A in its swiveled in position blocks. in this case, at the same time 13 via summarizes the ceiling of the joint portion 2 to the outwardly projecting part of the locking bar 12 and thus also prevents further pivoting of the staple leg a to the inside. to release the clip legs a from its arm encompassing position are the same at a outwardly projecting part of their joint parts 2 grasped by two fingers of one hand and against the action of the spring 9 in the watch case lugs 3 pushed in. As a result, the boxes 5 slide with their outwardly directed locking edges 5 '"from under the inwardly directed part of the locking strip 12, whereupon the clamp legs pivot upwards under finger pressure around their axle pins 7. When the finger pressure is released, the joint pieces 2 are again outward under the action of the spring pushed, and the locking edge 5 '"grasps the inwardly directed part of the locking strip 12 from above, whereby the clamp legs A are held in the open position. To put on the clip watch strap, all that is required is to pivot the clip legs A, with the locking edges 5 '"penetrating under the inwardly projecting parts of the locking strips 12 while the joint parts 2 slide back, so that the locking position according to Fig. 1 is reached again.
