Coupling device

Coupling device for a conveyor device which in particular is used for suspended transport of clothing, whereby the conveyor device comprises a support rail that is suspended and on which are suspended support straps that are equipped with rollers and whereby the rollers brace themselves on a support rail and the support straps hang, and whereby the support straps carry stay pipes having a longitudinal axis (5) and are arranged between adjacent stay pipe ends which may engage each other, comprising:

• coupling elements (1,2) each of which comprising a strip-shaped thin material and provided with a forward extending support web (4) and an arched web (6) which is located adjacent the support web (4), whereby the arched web (6) has an arc that is directed inward towards the axis (5) and a curve (10) whose maximum is positioned between the axis (5) and the support web (4);
• blocking devices (20,21,40,41,50,51) for selectively blocking a coupling connection between the coupling elements adapted for mounting on adjacent stay pipes (7), each said blocking device including a blocking block (22,42,53) which is adapted for mounting on one of said adjacent stay pipes and assigned to block one of said coupling elements (1,2) adapted for mounting on the other one of said adjacent stay pipes (7), whereby each said blocking block (22,42,53) includes a blocking position in which when the adjacent stay pipes (7) approaches each other for engagement, said blocking block would impact against said one of said coupling elements (1,2) before any coupling engagement would occur between the coupling elements, and a release position in which the blocking block (22,42,53) does not engage any one of said coupling elements (1,2) when the adjacent stay pipes approach each other for engagement;
• and
• the blocking blocks (22,42,53) are constructed to snap into their blocking and release positions.
