Shaft assembly, covering or protective device, and mounting kit

A mounting kit for flexibly mounting a shaft assembly for a furling unit of a covering or protection device, the mounting kit comprising:

• at least one of a first connecting sleeve and a second connecting sleeve, the first connecting sleeve being arranged for a first support bearing and a first end of a hollow section body, and the second connecting sleeve being arranged for a drive unit and a second end of the hollow section body,
• at least one pressure piece that is arranged to be disposed both between the first connecting sleeve and the hollow section body, and between the second connecting sleeve and the hollow section body, the pressure piece enabling rotation entrainment between the hollow section body and the connecting sleeves, and
• at least one biasing element that is arranged to be interposed both between a collar of the first connecting sleeve and the respective pressure piece, and between a collar of the second connecting sleeve and the respective pressure piece,
• wherein the at least one connecting sleeve is arranged to be inserted into the hollow section body against the force of the biasing element for mounting purposes.

A covering or protective device, comprising:

• a first support bearing,
• a second support bearing, and
• a shaft assembly that is interposed between the first support bearing and the second support bearing, the shaft assembly comprising a hollow section body that is mounted between the first support bearing and the second support bearing, and a drive unit that is at least partially arranged in the hollow section body,
• wherein the hollow section body is rotatable about its longitudinal axis and arranged to accommodate a curtain or a panel of the covering or protective device,
• wherein the drive unit comprises an output for rotatably driving the hollow section body,
• wherein the hollow section body comprises a first end facing the first support bearing and a second end facing the second support bearing,
• wherein a connecting sleeve is provided at least at one of the first end and the second end of the hollow section body,
• wherein a biasing element is arranged between the hollow section body and the connecting sleeve, and
• wherein the connecting sleeve is axially displaceable relative to the hollow section body against a preloading force that is applied by the biasing element, such that the shaft assembly is for mounting purposes axially telescopic against the preloading force.
