Claim 0:
1. A holding device for portable equipment, comprising:
a housing in which a roller element and a return element are arranged, wherein the roller element is arranged on the housing and is rotatably mounted in relation to the housing,
a tie for fastening equipment items, wherein the tie is completely rolled up on the roller element in an initial state and only one end of the tie protrudes from the housing, and
a bistable locking mechanism having a locked position and an unlocked position;
wherein:
the return element is arranged between the housing (1) and the roller element (2) in such a way that the return element exerts a tensile force on the roller element so that the tie can be rolled upon the roller element,
the tie can be unrolled and can be pulled out of the housing when a tensile force facing away from the housing is exerted on the tie, a force which is greater than the force exerted by the return element on the roller element, up to an end position in which the tie is completely unrolled from the roller element,
the tie can be rolled up to the initial state into the housing when a tensile force facing away from the housing is exerted on the tie, a force which is smaller than the force exerted by the return element on the roller element,
in the locked position of the locking mechanism, the rotation of the roller element in relation to the housing is blocked and the tie is rolled off by at least 80%,
in the unlocked position of the locking mechanism, the roller element is rotatable in relation to the housing, and
the locking mechanism can be changed between the locked position and the unlocked position by placing the tie in the end position, wherein:
the locking mechanism includes a cylinder, a piston and a spring element,
the cylinder, the piston and the spring element are arranged in the center of the roller element,
longitudinal axes of the cylinder, the piston and the spring element are coaxial and form a common longitudinal axis,
the cylinder is mounted in the roller element in a non-displaceable manner along the common longitudinal axis,
a first front end of the cylinder faces the roller element, and a second front end faces the piston,
the piston is mounted in the roller element in a non-displaceable manner along the common longitudinal axis and exhibits an extension section and a spring section, the extension section and the spring section being separated one from another by a shoulder,
the spring element is mounted on the shoulder, and at least partially surrounds the spring section, and
one end of the tie is fixed on the piston and the other end of the tie is guided through an opening in the roller element and through a recess in the housing.
