Fastener

Abstract

What is presented and described is a fastener, preferably for an orthosis, having a belt arrangement, comprising a first fastener part (1) and a second fastener part (21), which can be detachably connected to one another, wherein the first and the second fastener part (1, 21) comprise connection devices for belts of the belt arrangement, wherein the first fastener part (1) comprises a pin (3), wherein the second fastener part (21) has a connection end (23) and a coupling end (25), and a guide track (37) extending in a fastener plane is provided between the connection end (23) and the coupling end (25), said guide track extending from an entrance opening (41) to a guide track end (43), wherein the pin (3) comprises a first section (7) and a second section (9), wherein the dimension of the first section (7) perpendicular to the direction of extent of the pin (3) corresponds to the dimension of the guide track (37) in the fastener plane at the guide track end (43) and wherein the dimensions of the second section (9) perpendicular to the direction of extent of the pin (3) are greater than the dimension of the guide track (37) at the guide track end (43) such that the second section (9) restricts a movement of the pin (3) relative to the second fastener part (21) in a direction perpendicular to the fastener plane.

Description

technical field [0001] The invention relates to a buckle, preferably for an orthosis with a strap mechanism. Background technique [0002] Orthoses for stabilizing or immobilizing joints or for supporting body parts usually have a strap mechanism which rests in a suitable manner on the patient's body in order to fix the joint in question, for example in a prescribed position. At this time, it is usually necessary to apply force to the body through the strap mechanism, so that the strap mechanism must be under a certain pretension in the closed state of the orthosis. [0003] On the other hand, however, it is often the case that the patient's freedom of movement is restricted when the orthosis is already partly worn, so that he finds it difficult to properly connect the orthosis straps to one another. [0004] Thus, for example, in the orthosis for fixing the shoulder joint described in DE 19745705 C1, the patient is required to fix a plurality of strap ends with Velcro fast...

AI Technical Summary

Problems solved by technology

This is extremely difficult for patients whose freedom of movement is limited by orthotics on the one hand and, on the other hand, is often limited by injuries

[0005] In addition, the problem arises that the strap mechanism of this orthosis must be under a certain pretension in order to securely fix the problematic shoulder joint in the orthosis wearing position
