Abstract

A casing shell (10) for a belt buckle is described including at least one sidewall (12, 14, 16) which has an outwardly facing lateral face (22, 24, 26). A groove (23) extending perpendicularly to the longitudinal orientation (L) of the casing shell (10) completely over the lateral face (22, 24, 26) is provided on the lateral face (22, 24, 26). Furthermore a casing for a belt buckle is described.

Claims

1. A casing shell made of injection-molded plastic material for a belt buckle, comprising at least one sidewall extending in a longitudinal orientation of the casing shell between an upper side and a lower side, the at least one sidewall having an outwardly facing lateral face on which a groove is provided, the lateral face having a first lateral edge and an opposed second lateral edge, the groove extending partially through the at least one sidewall and perpendicularly to the longitudinal orientation of the casing shell from the first lateral edge to the second lateral edge, the at least one sidewall including a tapering portion within a transition area from the lateral face to the upper side on which at least part of a receiving aperture is formed for a plug-in tongue of the belt buckle.

2. The casing shell according to claim 1, wherein the tapering portion is formed on the at least one sidewall between the groove and the upper side.

3. The casing shell according to claim 1, wherein the at least one sidewall includes a curved outer contour.

4. The casing shell according to claim 1, wherein the groove is formed in an area of the at least one sidewall having a largest width of the lateral face.

5. A casing comprising the casing shell according to claim 1.

6. The casing according to claim 5, wherein the casing shell interacts with a further shell element, the shell element having a groove formed in a transition area.

7. The casing according to claim 5, wherein the casing includes four sides around which the groove continuously extends.
