A multi-directional coupling (10) consists of a tubular slipper (14) between a tubular member (12) and a race (16), there being engageable tubular friction surfaces (20, 36) on the slipper (14) and the race (16), and facing bearing surfaces (18, 22) on the tubular member (12) and the slipper (14) de

A multi-directional coupling (10) consists of a tubular slipper (14) between a tubular member (12) and a race (16), there being engageable tubular friction surfaces (20, 36) on the slipper (14) and the race (16), and facing bearing surfaces (18, 22) on the tubular member (12) and the slipper (14) defining therebetween a channel (28) with pockets (28a) receiving roller members (30), there being an actuator (e.g. a tooth (30)) on the tubular member (12) engaging a recess (40) in the slipper (14), or a spigot or a pin(s) or a cam engageable with the slipper (14) to provide two, three or four different modes of operation (e.g. lock-up, freewheel in both directions, freewheel in one direction and/or the other).

1. A coupling comprising:a first coupling member including a first friction surface; a second coupling member including a first bearing surface, and a first recess provided within the first bearing surface; a tubular slipper disposed between the first and second coupling members, the slipper including a second friction surface for engaging with the first friction surface, and a second bearing surface coaxial to the first bearing surface, the first and second bearing surfaces defining a channel therebetween for receiving a plurality of roller elements therein, the second bearing surface including a second recess, the first and second recesses together defining a pocket opening into the channel for retaining one of the roller elements therein, the pocket being configured for coupling the first coupling member to the second coupling member as the slipper and the second coupling member rotate relative to one another, and the first recess comprises a first arched recess and the second recess comprises a second arched recess complementary in shape to the first arched recess and disposed substantially opposite to the first arched recess.
