A fastening structure of a rangefinder wheel includes a first unit and a second unit. The first unit includes a first base which has a first passage defined axially therethrough for receiving a first tube therein. A lever is pivotably connected to the first base and has an engaging hole. A first spring and a second spring are biased between the first base and the lever. The second unit is pivotably connected to the first base and has a second base which has a second passage defined axially therethrough for receiving a second tube therein. An engaging member is connected to the second base and has a protrusion which is engaged with the engaging hole of the lever. The lever compresses the first spring to move a distance transversely. The lever compresses the second spring to move a distance axially so as to separate the lever and the engaging member.

A hinge assembly for use in an orthopedic or prosthetic system includes first and second connection members arranged to rotate relative to one another about at least one pivot point. At least one shaft member is rotatably attached to the first connection member. A translating member is attached to the at least one shaft member and is operatively connected to or meshes with the second connection member. Rotation of the at least one shaft member drives translation of the translating member along a length of the at least one shaft member. Translation of the translating member along the shaft member drives rotation of the second connection member relative to the first connection member.

A device including a ball, cage housing the ball and a centering lug, wherein the centering lug has a generally annular form with a radially outer annular periphery and a radially inner annular periphery, the outer annular periphery is integral with the cage and the inner annular periphery is inserted in a groove in the outer periphery of the ball, and the centering lug is elastic and arranged to hold the ball along a predefined axis in a rest position.

A pivoting fitting (1) comprises a first tab (2) and a second tab (3) which are mounted so as to be rotatable relative to each other about an axis (6), and a locking mechanism having at least one pawl (5) and toothing (4), wherein the pawl (5) can be engaged in the toothing in a plurality of positions and permits a pivoting movement of the first tab (2) with respect to the second tab (3) in a first direction and blocks movement in an opposing direction, and wherein at least one control element (14) is provided to disengage the at least one pawl (5) from the toothing (4) and then to pivot the first tab (2) with respect to the second tab (3) in the second direction through an angle, wherein the at least one pawl (5) is retained by a spring element (9) in a position engaged in the toothing (4), wherein the spring element (9) is at least partially made from an elastomer material. In this way, the pivoting fitting (1) can be pivoted with little noise.

A securing element for securing a spindle in a bushing, in particular for a medical stand device, includes a supporting portion configured to arrange the securing element in a predefined axial position on a supporting apparatus of the stand device, and an engagement portion configured to interact with a spindle rotatably supportable about an axis of rotation in the supporting apparatus, or a pin of the stand device, to secure the spindle or pin in a predefined axial position relative to the supporting apparatus rotatably within the supporting apparatus. The securing element can be supported in at least one radial position on the supporting apparatus, in particular in a mounting preparation position and/or a securing position, wherein the engagement portion is configured to interact with the spindle or the pin by engagement in the radial direction, in particular in the securing position. The securing element may also be secured in several radial positions and comprise coupling portions that are formed correspondingly. Also disclosed are components correspondingly formed to the securing element, in particular a supporting apparatus, a cover for the supporting apparatus, and a coupling element; and a securing system, or a securing mechanism, or a mounting set each comprising at least one securing element according to the invention.

Embodiments generally relate to hinge mechanisms. The central cylinder has a rotate channel transverse to the hinge axis. A collar may couple with the central cylinder and may include a pin that protrudes inwardly into the rotate channel. In some embodiments, the central cylinder may include a second rotate channel and the pin may extend through the first and second rotate channels of the central cylinder. In some embodiments, the central cylinder may include a tapered locking channel that extends and tapers in an axial direction from the rotate channel. Optionally, the collar may include an aperture for receiving the pin therethrough. The pin may be repositionable to a plurality of positions relative to the collar about an insertion axis. The pin repositioning may vary an axial position of the collar relative to the central cylinder, a rotational range of motion of the collar about the central cylinder, or both.
