  2. Pantograph - Wikipedia

    en.wikipedia.org/wiki/Pantograph

    Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...

  3. Five-bar linkage - Wikipedia

    en.wikipedia.org/wiki/Five-bar_linkage

    One of the links is the ground or base. [1] This configuration is also called a pantograph, [2] [3] however, it is not to be confused with the parallelogram-copying linkage pantograph. The linkage can be a one-degree-of-freedom mechanism if two gears are attached to two links and are meshed together, forming a geared five-bar mechanism. [1]

    en.wikipedia.org/wiki/Leg_mechanism

    A lambda mechanism combined with a parallelogram linkage to form a translating leg that follows the coupler curve. U.S. Patent No. 6,260,862, Walking Device, J. C. Klann (2001) . The coupler curve of a four-bar linkage guides the lower link of an RR serial chain to form a leg mechanism, known as the Klann linkage .

  5. Straight-line mechanism - Wikipedia

    en.wikipedia.org/wiki/Straight-line_mechanism

    The Scott Russell linkage (1803) translates linear motion through a right angle, but is not a straight line mechanism in itself. The Grasshopper beam/Evans linkage, an approximate straight line linkage, and the Bricard linkage, an exact straight line linkage, share similarities with the Scott Russell linkage and the Trammel of Archimedes.

    Linkage mobility Locking pliers exemplify a four-bar, one degree of freedom mechanical linkage. The adjustable base pivot makes this a two degree-of-freedom five-bar linkage. It is common practice to design the linkage system so that the movement of all of the bodies are constrained to lie on parallel planes, to form what is known as a planar ...

  8. Four-bar linkage - Wikipedia

    en.wikipedia.org/wiki/Four-bar_linkage

    If the linkage has four hinged joints with axes angled to intersect in a single point, then the links move on concentric spheres and the assembly is called a spherical four-bar linkage. The input-output equations of a spherical four-bar linkage can be applied to spatial four-bar linkages when the variables are replaced by dual numbers. [8]
