Definitions

  • the invention relates to a retractable, self-locking belt attachment with two loops looped through by the belt.
  • Such a belt attachment has become known from DE-GM 1 767 683.
  • the known belt fasteners are used as carrying devices, for example of breathing apparatus and rescue equipment.
  • the risers are tightened by simply pulling on the free, retractable belt part. This takes place in that the retractable belt part is first passed through two loops lying approximately one above the other and then between the two loops.
  • a self-locking closure is formed in one direction, since under the tensile force of the load, the retractable retractable belt part is pressed against one another, thus preventing unwanted loosening due to the high frictional force.
  • the two eyelets In order to eliminate this frictional force, the two eyelets must be slightly removed from each other. The distance between the two eyelets must then be maintained during retensioning. This requires laborious, two-handed manipulation.
  • the present invention is therefore based on the object to improve a belt attachment of the type mentioned so that the self-locking effect is canceled during re-tensioning and automatically re-occurs in the re-tensioned state.
  • a retaining eyelet is loosely encompassed by a sliding eyelet and the retractable belt part, S-shaped around the sliding eyelet, enters and exits within the retaining eyelet.
  • the advantages achieved by the invention are essentially that, in the tensioned idle state, the looped-through retractable belt part is held against one another both at the inlet end and at the outlet end between the holding eye and the sliding eye, so that a highly effective frictional force, even when dirty or oily, is less Rough surface of the belt, automatic loosening of the tight belt attachment prevented.
  • To re-tighten the belt fastening only the retractable belt part has to be gripped and pulled in the tensioning direction, whereby the sliding eyelet is released from the retaining eyelet and releases the friction surfaces of the belt lying on top of each other, whereupon a low-force re-tensioning is made possible.
  • the position of the belt fastening along the belt can be corrected and moved by lifting the sliding eyelet.
  • a carrying strap can expediently be provided on the holding eyelet.
  • lateral grip elements are provided on it for the purpose of loosening the belt attachment.
  • this stop can be designed as a grip ring.
  • FIG. 1 a holding eye (1) and a sliding eye (2) encompassing this are shown in section.
  • the sliding eye (2) Under the pulling action A in the direction of the arrow shown, as it becomes effective in the case of re-tightening of the belt (4), the sliding eye (2) is released from the holding eye (1), so that the belt (4) can be re-tensioned freely .
  • the eyelets (1, 2) are rectangular, so that a carrying strap (5) is attached to one side of the retaining eyelet (1).
  • the end of the retractable belt part (3) is formed into a loop (6) which carries a retaining ring (7) as a stop.
