Abstract
A device is provided for attaching a first part in the form of an instrument or tool to a second part in the form of a beam or such on a working machine having, on each of the parts, one engagement member fixed thereto, which are designed to be driven into engagement with each other so that the force of gravity on the first part holds the parts attached to one another. A first (17) of the engagement members is of the male-type having external surfaces converging towards each other and a second of the engagement members is of the female-type having internal surfaces converging towards each other in a corresponding way to said surfaces of the first engagement means for receiving and holding the first engagement means in the second engagement means under the influence of the force of gravity on the first part.

Device for attaching a first instrument or tool part (3-5) to a second part (2) in the form of a beam or on a working machine, comprising
- first (17) and second (7) engagement means respectively fixed to one of the first (3-5) and second (2) parts,
- said first (17) and second (7) engagement means structured and arranged on the respective parts (2-5) to be driven into engagement with each other such that the parts (2-5) are thereby held attached to each other under the force of gravity of the first part (3-5) upon the second part (2),
- said first (17) engagement means include a male engagement member having external surfaces (14, 15) converging towards each other,
- said second (7) engagement means include a female member having internal surfaces (8, 11) converging towards each other in a corresponding way to said external surfaces (14, 15) of said first engagement means (17), to receive and hold said first engagement means (17) in said second engagement means (7) under the influence of the gravitational force of the first part (3-5) upon the second part (2) to push said external converging surfaces (14, 15) substantially in the direction of convergence against said internal converging surfaces (8, 11) and into a fixed position in which said respective externally (14, 15) and internally (8, 11) converging surfaces fit tightly together, and
- an arrangement to fixedly lock the second part (2) to the first part (3-5) and with a recess (19) in a surface (8) of one (3-5) of the parts (2-5), and comprising
- a wedge element (20) movably arranged on the other (2) of the parts (2-5),
- means (25) for inserting said wedge element (20) in the recess (19) such that surfaces of said wedge element (20) are pressed against walls of the recess (19) and locking said wedge element (20) non-movably in the recess (19),
- resilient means (24) arranged to be compressed, store potential energy and only act on said wedge element (20) to press said wedge element (20) into the recess (19) during biasing of said resilient means (24) by said inserting means (25) in said locked position, and not act upon said wedge element (20) in absence of such biasing by said inserting means (25), such that said wedge element (20) remains retracted, and
- said inserting means (25) are positioned between said wedge element (20) and said resilient means (24).
