CHILDREN'S ORTHOSIS SUPPORT DEVICE WITH TELESCOPIC HEIGHT ADJUSTMENT, GRADUAL ANGULAR POSITIONING, MECHANICAL LOCKING AND MODULAR CONNECTION MECHANISM.

Abstract

The invention relates to a modular pediatric orthotic support device (1) in which the carrier geometry can be mechanically changed and the specified linear and angular positions can be mechanically maintained. The modular pediatric orthotic support device (1) includes a main carrier body (2), upper carrier module (3), lower carrier module (4), telescopic height adjustment mechanism (5), stepped angular positioning and locking mechanism (20), modular connection mechanism with geometric positioning (28) and a repositionable anatomical support element (32).In the telescopic height adjustment mechanism (5), the relative linear movement of the outer telescopic carrier profile (6) and the inner telescopic carrier profile (7) is guided by the matching linear movement guide channel (8) and linear movement guide projection (9), limiting unintentional relative rotation and lateral displacement; the selected height position is maintained by one of the stepped height position locking slots (10) and the positive mechanical engagement of the spring-loaded height position locking pin (11).In the stepped angular positioning and locking arrangement (20), the first joint connecting piece (17) and the second joint connecting piece (18), which move relative to each other around the joint rotating shaft (19), can be brought to different angular positions by the mechanical matching of the stepped angular positioning teeth (21) and the angular positioning tooth counterpart (22); the selected position is mechanically protected by the angle locking latch (23) and the angle lock is limited against unintentional release by the secondary safety element (27). In the geometrically positioned modular connection arrangement (28), the mutual geometric matching of the module geometric positioning slot (29) and the module geometric positioning projection (30) defines the relative connection position of the modules and the module fixing element (31) mechanically fixes this position.The anatomical support element (32) can be repositioned along the anatomical support linear positioning channel (33) and mechanically fixed in the selected position with the anatomical support connection element (34). Thus, linear length adjustment, stepped angular positioning and locking, geometrically defined modular connection and anatomical support positioning functions are realized within a common carrier architecture as complementary mechanisms controlling separate mechanical variables.
