When a filter cartridge, replaced in a water purification system, or various objects (elevated bodies) needed to be elevated (an opposite concept of ascent and descent) are elevated by repeatedly pushing the same, the elevated body can be elevated in the right direction by only pushing the elevated body repeatedly as a stop function in a state that the elevated body has been elevated and a descending function by release in a state that the elevated body is stopped are repeatedly performed. A user can audibly recognize a decent completion state. The locking-unlocking structure can be implemented by only changing a structure without using an additional component. When an elevated plate having a stop protrusion, which is mounted on an stop groove of an operation guiding unit formed in the shape of a plate or moves between an elevation line and a descent line, and is elevated; an elastic piece is arranged on the descent line and a guide protrusion, which is gradually elevated to a front end portion of the elastic piece, is arranged to make the stop protrusion elevated along the elevation line during the elevation and to make the stop protrusion elastically operate during the decent to the decent line to make the decent easy. The locking-unlocking structure enables the user to audibly check completion of the descent by generating pleasant sound as the stop protrusion, sliding and descending along a guide protrusion of the elastic piece, escapes from the guide protrusion and then collides with the elevation plate to be attached to the stop protrusion.

Deployable compliant mechanism

A mechanism is hereby disclosed that, when activated in the linear direction of its axis, will expand and contract radially. The novel nature of the device is that of compliant methods and materials used in its design. Compliant members, referred to as dyads, translate the motion and imply resistance in a single structure. Thus eliminating the need for separate members, hinges, pins, springs and the associated assembly. When these compliant dyads are combined in the novel configurations hereby disclosed, a device is created that expands (or contracts) in multiple directions from its primary axis of actuation. Furthermore, one or more actuation dyad sets could be arranged at various angles relative to the global vertical axis. The radial expansion/contraction can be 2D or 3D by adding more primary activation dyad sets. Such a device can be applied to many applications and industries. One such application is for gripping the inside of a tube or object for moving manually or in automation. The compliant nature of this device can be optimized to auto-adapt to the objects size and shape allowing for greater part variation and reduce manufacturing line change-over times. Other applications would include snap fit connections, spherical articulating joints, spinning cutting tools, speed limiting using friction and centrifugal force, braking rotational forces or transmitting it, automatic centering, expanding elastic bands in an assembly process, and stretching an opening for fitment. The design of this device is material friendly and can be made of plastic, composite and metals. It may be of a single monoform construction (created by molding, machining, or additive manufacturing) or made of multiple parts including pivots and different materials to achieve the desired articulation.
