The description relates to hinged devices, such as hinged computing devices. One example can include first and second portions that rotate around a hinge shaft that is fixedly secured to the first portion and rotationally secured to the second portion. The second portion defining a first contact surface spaced apart from a second contact surface. Multiple friction clips friction fit around the hinge shaft and rotating with the hinge shaft between the first contact surface and the second contact surface.

A ride vehicle for an attraction of an amusement park includes a ride seat, a pivot adapter configured to rotate relative to the ride seat, a gear of the pivot adapter comprising a first set of teeth, a passenger restraint piece coupled to the pivot adapter and configured to rotate with the pivot adapter between a closed and an open position, and a cap having a second set of teeth. The cap is configured to be positioned to engage the gear of the pivot adapter such that the second set of teeth of the cap engages with the first set of teeth of the gear, and engagement between the second set of teeth and the first set of teeth substantially blocks movement of the pivot adapter relative to the ride seat in a rotational direction.

A rotatable connection for a stand apparatus to be arranged in an operating room and including an adaptable stop mechanism which can be arranged between a first connection component and a second connection component mounted rotatably around a rotational axis relative to the first connection component and is configured to define at least two different relative rotational angles of the connection components or at least two different rotational ranges is provided. A carrier system or a stand apparatus having such a rotatable connection is also provided.

A button lock that selectively retains the angle of an object relative to a handle. The button lock is rotatable between an engaged position, where the angle is retained, and a disengaged position, where the object is disengaged from the handle and can pivotally move about the handle to change the angle. In the engaged position, button teeth on the button engage with handle teeth on the handle. In the disengaged position, the button teeth disengage the handle teeth to space the button from the handle and therefore allow free movement of the handle about the button. The button therefore quickly and easily retains the angle between the object and the handle.

A fastening apparatus includes: a base having a first sliding groove; a rotation member pivotally connected to the base and having at least two locking states, the rotation member has a second sliding groove; a locking member having a locked state and an unlocked state, in the locked state, the rotation member is located in both the first sliding groove and the second sliding groove; in the unlocked state, the locking member is withdrawn from the first sliding groove or the second sliding groove to allow the rotation member to rotate relative to the base; an elastic element configured to maintain the locking member in the locked state; and a releasing member configured to drive the locking member to move against an elastic force of the elastic element, such that the locking member is switched from the locked state to the unlocked state.
