Device for arranging, clamping or contracting a ring shaped securing mechanism

Method of mounting, clamping or contracting an annular retaining element, such as a press ring, a clamping ring or contract ring, by means of a device comprising

• an open clamping ring (3) prestressed in a closing direction, with a retaining section (5, 7) at each end,
• at least two annularly curved clamp jaws (11) largely laterally abutting, mounted inside the clamping ring, resting with their outer, annular contour (12) against the clamping ring, and together forming at least an almost circular ring opening with an inner, annular surface (19),
• at least one spring-like element (15) between laterally abutting clamp jaws to push them away from each other and to open up the clamping ring in unclamped status in the direction enlarging the ring opening diameter and holding the clamp jaws firmly in the inwardly prestressed clamping ring, wherein all the clamping jaws are independently retained within the clamping ring by the inward prestressing of the clamping ring and outward pushing of the spring-like element on the clamp laws, and
• a clamping element (30) provided with at least two gripping sections (31, 33) in order to grip the retaining sections and clamp the open clamping ring in the diameter-reducing direction, comprising the steps of:
• arranging the retaining element within at least two clamp laws;
• forming a largely circular ring opening with inner surfaces of the clamp laws and providing spacing between two clamp laws by a spring-like element that laterally pushes the two clamp laws away from each other;
• clasping the outside of the clamp laws and holding them by an open clamping ring,
• clamping the open clamping ring by means of a clamping element, and
• moving the clamp laws in the diameter reducing direction by pushing the clamp jaws largely radially and vertically inward to clamp and/or contract the retaining element on an object.
