Abstract
An orthotic caliper having at least two lockable steels for attachment to the respective limb members of the human body and having a locking pivotal connection between the steels, characterized by a releasable locking member which can be loaded in compression by the steels and which acts directly on at least one of the steels, and preferably on both of them, to lock them in a desired position when so loaded.
Claims8
An orthotic caliper having at least two steels for attachment to two respective limb members of the human body, pivotal connection means connecting the two steels together so as to form a pivotal joint between the steels, the pivotal connection means thereby allowing the steels to rotate with respect to each other so as to permit the steels to take up a variety of angular positions with respect to each other, a releasable locking member arranged to abut and thereby act directly on at least one of the steels to lock the steels in a predetermined desired position against rotational movement in both directions relative to each other, said desired position being selected from the variety of relative positions which the steels are able to take up, and means on the steels which act on the locking member to apply compressive forces to said member when the steels are locked in said desired position, said compressive forces serving to hold the locking member in its locking position, and the releasable locking member being free to move, as the steels are brought into said desired position, in order to abut the said surface on said one steel.
