Clamp hand protector

In a clamp hand protector for use on a toggle-type pivotally interconnected three-linkage-elements clamp, wherein a first clamp linkage element is provided with an outwardly extending spatulate operating handle member having a second linkage element pivotally connected thereto adjacent to a junction between a lower end of said operating handle member and an upper end of said first clamp linkage element, the provision of:

• a pusher-type, toggle-form, positively locking and unlocking by an overcenter movement and the reverse thereof, pivotally interconnected three-linkage-elements clamp, including a longitudinal first clamp linkage element provided at an inner bottom end thereof with, and being transversely pivotally attached to a fixedly mounted base member, which in turn is provided with first pivotal mounting means comprising first pivot pin means pivotally interconnecting said inner bottom end of said first linkage element with said fixedly attached base member for rotation around a first pivot pin axis transverse to the longitudinal direction of said first linkage element, with said longitudinal first linkage element having an outer junction portion at the outer uper end thereof provided with and rigidly joined to a longitudinally aligned, outwardly extending, spatulate operating handle member, and further including a longitudinal second clamp linkage element having a rear and upper-when-locked end provided with second pivotal mounting means comprising second pivot pin means pivotally interconnecting said rear and upper-when-locked end of said second linkage element with said outer and upper junction portion at the outer upper end of said longitudinal first clamp linkage element at a location higher than and spaced above said first pivot pin means when said first and second linkage elements are forcibly manually moved forwardly into clamp-locked relationship by correspondingly forcibly manually moving said operating handle forwardly, and further including a longitudinal third clamp linkage element having a rear-when-locked end provided with third pivotal mounting means comprising third pivot pin means pivotally interconnecting said rear-when-locked end of said third clamp linkage element with said fixedly mounted base member at a location upwardly, outwardly and rearwardly displaced from the location of said first pivot pin means, with said longitudinal second linkage element having a forward and lower-when-locked opposite end provided with a fourth pivotal mounting means comprising a fourth pivot pin means pivotally interconnecting said forward and lower-when-locked opposite end of said second linkage element with said third linkage element at an intermediate location spaced directly forwardly of said third pivot pin means when said first, second and third clamp linkage elements are in clamp-locked relationship;
• an edge-of-hand protective shield provided with mounting means cooperable with the composite effectively joined first clamp linkage element and operating handle member coupled thereto adjacent to an intermediate junction or coupling region therebetween at a location adjacent to said junction portion and effectively separating shielding and isolating said handle member from a second linkage element pivotally connected to said first linkage element adjacent to the inner end of said handle member for effectively preventing the movement of an operating human hand grasping the handle member into an arcuately-variable-angle junction region between the first and second pivotally interconnected linkage elements.
