Abstract
A fixing clamp for an aligning device, and an aligning device that includes the fixing clamp, for clamping to a bodily extremity. The clamp includes a first clamp arm, a second clamp arm and a frame device having an attaching section for attaching to an adjustment rod. The first clamp arm is rotatably attached to a first rotary joint about a first axis of rotation, and the second clamp arm is rotatably connected to a second rotary joint about a second axis of rotation. A locking mechanism locks the first clamp arm and/or the second clamp arm relative to the frame device in at least one position, and blocks movement of the first or second clamp arm about the respective rotary joint in an open rotational direction.
Claims20
A fixing clamp for an aligning device for fixingly clamping a body extremity, the fixing clamp comprising:
- a first clamp arm and a second clamp arm;
- a frame device forming a bearing trough or bearing fork for the body extremity, the frame device having a central mounting or attaching portion for mounting or attaching to an adjustment rod of the aligning device and having a first rotary joint and a second rotary joint at two bearing fork ends of the frame device, to which the first clamp arm is articulated rotatably about a first axis of rotation and the second clamp arm is articulated rotatably about a second axis of rotation;
- and
- a self-locking mechanism comprising two latching mechanisms that frictionally and/or form-fittingly hold or latch the first clamp arm and the second clamp arm relative to the frame device in at least one position independent from each other and thereby block a movement of the first and second clamp arm about the first rotary joint and second rotary joint, respectively, in an opening rotation direction.
A fixing clamp for an aligning device for fixingly clamping a body extremity, the fixing clamp comprising:
- a first clamp arm and a second clamp arm;
- a frame device forming a bearing trough or bearing fork for the body extremity, the frame device having a central mounting or attaching portion for mounting or attachment to an adjustment rod of the aligning device and having a first rotary joint and a second rotary joint at two bearing fork ends of the frame device, to which the first clamp arm is articulated rotatably about a first axis of rotation and the second clamp arm is articulated rotatably about a second axis of rotation;
- and
- a self-locking mechanism comprising a latching mechanism that frictionally and/or form-fittingly holds or latches the first clamp arm and/or the second clamp arm relative to the frame device in at least one position and blocks a movement of the first and/or second clamp arm about the first rotary joint and/or second rotary joint, respectively, in an opening rotation direction.
A fixing clamp for an aligning device for fixingly clamping a body extremity, the fixing clamp comprising:
- a first clamp arm and a second clamp arm;
- a frame device forming a bearing trough or bearing fork for the body extremity, the frame device having a central mounting or attaching portion for mounting or attachment to an adjustment rod of the aligning device and having a first rotary joint and a second rotary joint at two bearing fork ends of the frame device, to which in each case the corresponding first clamp arm is articulated rotatably about a first axis of rotation and the second clamp arm is articulated rotatably about a second axis of rotation;
- and
- a self-locking mechanism comprising a latching mechanism that frictionally and/or form-fittingly holds or latches the first clamp arm and/or the second clamp arm relative to the frame device in at least one position and blocks a movement of the first and/or second clamp arm about the first and/or second rotary joint, respectively, in an opening rotation direction, wherein the first clamp arm and/or the second clamp arm is pretensioned in the opening rotation direction opposite to a closing rotation direction.
