The toggle-joint is an old, well-known, and extensively-used mechanical device for exerting pressure; and it consists, essentially, of two links hinged together end to end and connected at their opposite ends to the mechanism tobe operated. These joints as ordinarily made are expensive and difficult of construction; and the object of my ...

The toggle press is anchored in the head. The upper joint pivots in this anchor while the lower joint follows an curved path. This means that the ram path changes. This path (Figure 25.4) can be modified by changing the arrangement of the joints. Figure 25.4 Time-displacement diagram for a toggle press Crank angle D c (degrees); time until ...

A toggle joint is a common mechanism that can be used to generate a large force P by a much smaller applied force Q . Given the toggle joint shown below, use FBDs and equilibrium to derive an equation that gives the value of the force P for an applied Q for any joint angle α . Friction can be ignored.

5-46. A toggle joint is a mechanism by which a comparatively small force P produces or balances a force F that increases rapidly as the angle θ approaches 18 0 ∘. For a given angle of θ, the toggle joint becomes equivalent to a simple truss. Force P = 10 lb, a = 2 ft, b = 5 ft, and c = 1 ft, as shown.
