A railing system having a number of spaced apart support bases and a railing is provided. The railing includes a number of vertically extending stanchions connected to the support bases and a number of horizontally extending members extending between the vertically extending stanchions. The railing is configured to be shifted relative to the support bases between a stored position and an erected position. The railing is automatically secured in the erected position when the railing is shifted from the stored position to the erected position.

The invention relates to an implement coupling device (1) on a working machine (2), which device comprises a coupling means (11) provided with a first shaft (21); an engagement means (12) provided with a second shaft (22) arranged parallel to the first shaft (21); at least one linkage (13, 14) comprising a first portion (23, 24) connected to the first shaft (21) and second portion (25, 26) connected to the second shaft (22), which first and second portions are connected by a pivot joint (27); and a wedge (28) means arranged to be removably mounted between the first and second portions (23, 24; 25, 26), wherein the coupling means (11) and the engagement means (12) are displaceable relative to each other in a direction at right angles to the first and second shafts (21, 22) to attach or release the implement. At least one portion (23, 24; 25, 26) making up a linkage (13, 14) is detachably fixed to its respective shaft (21, 22) by a locking means (31, 32, 33, 34) in a longitudinal recess (41, 42, 43, 44) at right angles to the shaft (21, 22) and engaging with a tangential recess (51, 51′, 51″) in the outer surface of the shaft (21, 22).

A mounting fixture for positioning a workpiece in a desired relationship with an apparatus including an articulation joint for coupling first and second tubular members in a desired angular relationship. The articulation joint includes a first end portion clamped to an interior surface of the first tubular member and a second end portion clamped to an interior surface of the second tubular member. First and second clamping members of the articulation joint are clamped together to prevent pivotable movement between a first articulation member and a second articulation member of the articulation joint.

A vehicle light device comprising an element made up of a plurality of portions each having a functional surface, at least two consecutive portions being linked together by an articulation. The main feature of a light device according to the invention is that each articulation allows the displacement of the two consecutive portions until their functional surfaces come into continuity with one another.
