DEVICE FOR POSITIONING AN OBJECT AT A USER-ADJUSTED POSTION

摘要

A device is provided for positioning an object with respect to another object. The device includes a linkage having an extended condition and a collapsed condition, the linkage including at least one pair of links coupled to one another about a pivot rotation axis. The device also includes a friction element positioned at the pivot rotation axis of the at least one pair of links of the linkage, A spring of the device is positioned to apply bias to the links of the at least one pair of links of the linkage. The device is configured to resist unintended movement of the object from the user-adjusted position along the path and to facilitate intended movement of the object proximally toward or distally away from the other object.

1. A device for positioning an object at a user-adjusted position along a path with respect to another object, the device comprising:
a linkage having an extended condition in which the object can be positioned distally away from the other object and a collapsed condition in which the object can be positioned proximally toward the other object, a distal end of the linkage being configured to be coupled to the object and a proximal end of the linkage being configured to be coupled to the other object; a friction element coupled to the linkage and configured to generate friction that resists movement of the linkage from the extended condition to the collapsed condition; and a spring coupled to the linkage and configured to bias the linkage toward the extended condition.
