Abstract

A device for easily and quickly connecting an end part (4) of a band (3) to a further part (1), in particular a wristband (3) to a further part (1) such as a watchband (3) to a watch casing (1), wherein a pin (2) arranged at the end part (4) of the band (3) and extending, with its longitudinal axis, transversely to the longitudinal direction of the band (3) can be engaged with at least one recess (6) of the rigid part (1), is characterized in that the end part (4) is detachably connectable to the band (3) by means of a form-fitting connection (10, 22) to be operated by hand.

Claims

1. A device for connecting an end part (4) of a band (3) to a further part (1), in particular a wristband (3) to a further part (1) such as a watchband (3) to a watch casing (1), wherein a pin (2) arranged at the end part (4) of the band (3) and extending, with its. longitudinal axis, transversely to the longitudinal direction of the band can be engaged with at least one recess (6) of the rigid part (1), characterized in that the end part (4) is detachably connectable to the band (3) by means of a form-fitting connection. (10, 22), preferably a snap connection, to be operated by hand.

2. A device according to claim 1, characterized in that the form-fitting connection (10, 22) comprises two lugs (10), preferably key heads, which are movable against one another and whose moving direction is provided in parallel to the pin (2), and which lugs (10) are engageable, in each case, with a lug notch (22) of the counterpiece, in particular of the band (3).

3. A device according to claim 1, characterized in that, for mounting the end part (4) with the band (3), guide surfaces (15) and opposite guide surfaces (24) corresponding to each other and preferably designed with dovetail cross-sections are provided both at the end part (4) and on the band (3).

4. A device according to claim 3, characterized in that the guide surfaces (15) and the opposite guide surfaces (24) are oriented roughly vertically to the band plane.

5. A device according to claim 2 characterized in that the lugs (10) are provided in the end part (4).

6. A device according to claim 5, characterized in that the lugs (10) are in a moved-apart state if the end part (4) is connected to the band (3).

7. A device according to claim 6, characterized in that a spring (9), in particular a helical spring (9), pressing the lugs apart is provided in the end part (4).

8. A device according to claim 6, characterized in that the end part (4) comprises a retaining part (18) receiving the lugs (10) as well as optionally the guide surfaces (15), which retaining part is narrower than the width (20) of the band (3) and is insertable into a recess (17) of the band (3) exhibiting the lug notches (22) as well as optionally the opposite guide surfaces (24) and encompassing the retaining part (18) in a U-shaped manner.

9. A device according to claim 1, characterized in that the guide surfaces (15) of the band (3) as well as the lug notch (22) and optionally the lugs (10), respectively, are housed in a casing (16) which is cast integral with the band (3) or glued or welded to the same or which is cast or moulded integral with the same, respectively.

10. A device according to claim 1, characterized in that the lugs (10) are provided with actuating extensions (13) oriented toward the bottom side of the end part (4) or of the band (3), respectively, and preferably projecting beyond the same for detaching the lugs (10) from the lug notches (22).

11. A device according to claim 1, characterized in that the band (3) and/or the casing (16) is/are provided with a cover (21) overlapping the end part (4).
