Definitions

  • the innovation relates to a belt buckle according to the preamble of claim 1.
  • a buckle according to the preamble of claim 1 is also referred to as a carabiner lock, in which the first slot is bridged by a pivotable, spring-loaded lever. To open and close the lock, it is necessary to depress this lever in the direction of the first slot so that the slot opening is released. If the belt buckle is used in a belt that is to be quickly closed and opened, this type of lock actuation is cumbersome. This applies, for example, if the buckle is used for the belt of a life jacket.
  • a belt buckle with a pocket-shaped lock part is the subject of US-A 4 712 280. This has two pocket-shaped recesses on the side.
  • the other lock part is provided with two elastic tongues, each of which has a barb.
  • the other lock part becomes one lock part inserted, then the barbs reach behind the respective edge of the bag.
  • the tongues must be pressed against each other with two fingers.
  • the disadvantage here is that wear can occur on the barbs and on the edges of the pockets interacting with the barbs when the belt buckle is used frequently, which affects the safe functioning of the belt buckle, especially if one takes into account that the belt tension at the locking points between barbs and the Edges attack. If the user of the belt buckle wears mittens, he must remove them to open the buckle.
  • the other belt buckle can be inserted into one part of the belt by two positions offset by 180 ° to one another.
  • Another belt buckle is the subject of DE-A 25 39 277.
  • a guide track is provided for a locking projection on a tongue of the other lock part.
  • This guideway is first hook-shaped and then to a turning point and back to the insertion opening.
  • To lock the one lock part is inserted into the pocket of the other lock part until the locking projection engages behind the hook-shaped part of the guideway.
  • To open the two parts of the lock are guided against each other until the locking projection slides over the turning point.
  • the disadvantage here is that the belt tension acts on the locking projection of the tongue.
  • the second lock part can be inserted so far into the pocket-shaped lock part, whereby the lock is opened.
  • This buckle is therefore unsuitable as a buckle on rescue equipment, such as life jackets.
  • the object is to design the buckle in such a way that, with a secure hold in the closed position, it can be opened in a simple manner even when the belt is under tension.
  • the first lock part 1 which consists of a flat material, has a belt feed-through slot 2 in a known manner.
  • the height of the nose 5 is designated 6.
  • the nose 5 points in the direction of the belt passage slot 2.
  • a hook-shaped lock part is formed, the hook of which is designated by 7.
  • the outer edge 8 of the hook extends obliquely so that the hook 7 tapers in the direction of the slot mouth 4.
  • the second lock part 10 is U-shaped in cross section, the free legs 11, which are connected to one another by a wall 12, also each having belt through-slots 2.
  • a spring part 13 is inserted between the two free legs 11 and at a distance from the wall 12.
  • This flat spring part 13, which is made of an elastic plastic, also has a belt feed-through slot 2 which is aligned with the belt feed-through slots 2 of the legs 11.
  • the spring part 13 is rigidly connected to the second lock part 10 via the bores 14.
  • the Spring part 13 has a tongue 16 which extends obliquely into a second slot 15 which is open on both sides and is delimited by the wall 12, the legs 11 and the spring part 13.
  • the hook 7 is inserted into the slot 15 until the nose 5 engages over the wall 12.
  • the outer edge 8 of the hook 7 slides along the tongue 16, which is deformed to the right about its hinge point 17.
  • the tip of the tongue 16 bears against the outer edge 8 of the hook 7, with which the wall 12 is held against the inner edges 18 of the hook 7. The closed position is thus properly secured.
  • the two lock parts 1, 10 are moved against each other, the tongue 16 being deformed to the right.
  • the mutual movement and thus the deformation of the tongue 16 is effected at least according to the height 6 of the nose 5, the wall 12 then no longer being engaged by the nose 5 and the hook 7 can thus be guided out of the slot 15.
  • the tongue 16 ensures a secure hold in the closed position.
  • To open the two lock parts 1, 10 must be moved against each other only by the height 6 of the nose 5, which can also be carried out with the belt tightened. Since only a small linear movement is required to unlock the buckle, the buckle is particularly suitable for belts that are to be opened quickly and safely, such as life jackets.
