Abstract
Abstract The apparatus comprises a leverage including at least two parallel arms pivotally mounted at their central portions, having one pair of the ends threof spread by the end piece of a driving rod and actuated, for instance, by a solenoid. The opposite pair of ends of the arms is operatively connected with a driven rod by means of wedge type engagement. Rollers are interposed between the contact surfaces of the arms and the respective rods. The mechanism cuts down the amount of energy required for transmitting a command, offers fast action and reliability.

Claim 1
Independent Claim
353 words
In an apparatus for transmitting a command signal from a linearly displaceable driving member to a driven member which is displaceable in response to the command signal, a command signal transmission assembly comprising two arms having pivotally mounted central portions and opposite end portions, one pair of the end portions of said arms straddling the driving member to be retained in a normal position, either spread apart or brought together, by said driving member, the opposite pair of the end portions of said arms being in operative engagement with said driven member to hold the same in position, said driven member having a wedge-shaped end piece, said arms engaging said wedge-shaped end piece in a wedged relation therewith, said driving member and said driven member being axially aligned and comprising axially displaceable rods with respective end pieces facing each other, said arm having pivot axes extending transversely of the axes of the rods, and resilient means acting on the driven member to urge the arms apart by said wedge-shaped end piece, said end piece of said driving member normally urging said opposite end portions of the arms apart, the driving member being displaceable by a command signal to produce pivoting of said arms and displacement of said driven member, intermediate rolling bodies interposed between the wedge-shaped surface of the end piece of the driven rod and the end portions of the arms adjacent thereto and further rolling bodies interposed between the engagement surfaces of the opposite end portions of the arms and the end piece of the driving rod, said rolling bodies cooperating with planar engagement surfaces of the arms of the end pieces of the rods, said rolling bodies being in the form of rollers extending transversely of the common axis of the rods and parallel to the pivot axes of the arms, and wherein in the area of the engagement between the driving rod and the adjacent end portions of the arms a single one of said rollers is located on one side of the end piece of said rod and two said rollers are located on the opposite side thereof.

In an apparatus for transmitting a command signal from a linearly displaceable driving member to a driven member which is displaceable in response to the command signal, a command signal transmission assembly comprising two arms having pivotally mounted central portions and opposite end portions, one pair of the end portions of said arms straddling the driving member to be retained in a normal position, either spread apart or brought together, by said driving member, the opposite pair of the end portions of said arms being in operative engagement with said driven member to hold the same in position, said driven member having a wedge-shaped end piece, said arms engaging said wedge-shaped end piece in a wedged relation therewith, said driving member and said driven member being axially aligned and comprising axially displaceable rods with respective end pieces facing each other, said arm having pivot axes extending transversely of the axes of the rods, and resilient means acting on the driven member to urge the arms apart by said wedge-shaped end piece, said end piece of said driving member normally urging said opposite end portions of the arms apart, the driving member being displaceable by a command signal to produce pivoting of said arms and displacement of said driven member, intermediate rolling bodies interposed between the wedge-shaped surface of the end piece of the driven rod and the end portions of the arms adjacent thereto and further rolling bodies interposed between the engagement surfaces of the opposite end portions of the arms and the end piece of the driving rod, said rolling bodies cooperating with planar engagement surfaces of the arms of the end pieces of the rods, said rolling bodies being in the form of rollers extending transversely of the common axis of the rods and parallel to the pivot axes of the arms, and wherein in the area of the engagement between the driving rod and the adjacent end portions of the arms a single one of said rollers is located on one side of the end piece of said rod and two said rollers are located on the opposite side thereof.
Claim 3
Dependent Claim
54 words
An apparatus according to claim 1, wherein the end piece of the driven member is shaped as an inverted wedge tapering in a direction opposite to that toward the pivot axes of the arms, the latter having their engagement end portions, adjacent to the end piece of the driven member, shaped as clamping jaws.
