Abstract
Abstract A remote control directional mechanism which enables to operate a knuckle boom-type loader along three orthogonal directions from a single operating handle. The boom of the loader will move along directions similar to the ones of the handle moved by an operator. The mechanism per se includes two interconnected angularly deformable quadrilateral arrangements of four arms, each arrangement having a hydraulic cylinder therein, the longitudinal variation of the cylinder permitting the corresponding actuation of the loader.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
300 words
A remote control mechanism for transmitting motions in at least two orthogonal directions, said mechanism comprising: a first control device having a variable length, a first elongating means for said first control device to allow a variation of the length of the first control device, the said first means defining a first deformable quadrilateral arrangement of four arms, a movable operating lever connected to the first elongating means for varying the length of the first control device, the direction of movement of the lever being parallel to the length of the first control device, a second control device having a variable length and disposed at 90* with the first control device, second elongating means for said second control device so as to allow a variation in length of the second control device, the said second means defining a second deformable quadrilateral arrangement of four arms, means for interconnecting the two elongating means so that a movement of the said operating lever in a direction parallel to the length of the second control device varies the length of the said latter device, means for operatively connecting the said control devices to an orthogonal motion actuating system so that a movement of of the same operating lever serves to produce corresponding orthogonal movements of the actuating system, wherein the first quadrilateral arrangement comprises a first arm rigidly immovable; a second arm pivotally connected to said first arm through which is mounted the first hydraulic pressure device; a third arm opposed to the first arm and pivotally connected to the second arm, the operating lever being connected about the intersection of the second and third arms for longitudinally varying the length of the first hydraulic pressure device; a fourth arm opposed to the said second arm and pivotally connected to the third arm.
Claim 2
Dependent Claim
300 words
A remote control mechanism for transmitting motions in at least two orthogonal directions, said mechanism comprising: a first control device having a variable length, a first elongating means for said first control device to allow a variation of the length of the first control device, the said first means defining a first deformable quadrilateral arrangement of four arms, a movable operating lever connected to the first elongating means for varying the length of the first control device, the direction of movement of the lever being parallel to the length of the first control device, a second control device having a variable length and disposed at 90* with the first control device, second elongating means for said second control device so as to allow a variation in length of the second control device, the said second means defining a second deformable quadrilateral arrangement of four arms, means for interconnecting the two elongating means so that a movement of the said operating lever in a direction parallel to the length of the second control device varies the length of the said latter device, means for operatively connecting the said control devices to an orthogonal motion actuating system so that a movement of of the same operating lever serves to produce corresponding orthogonal movements of the actuating system, wherein the first quadrilateral arrangement comprises a first arm rigidly immovable; a second arm pivotally connected to said first arm through which is mounted the first hydraulic pressure device; a third arm opposed to the first arm and pivotally connected to the second arm, the operating lever being connected about the intersection of the second and third arms for longitudinally varying the length of the first hydraulic pressure device; a fourth arm opposed to the said second arm and pivotally connected to the third arm.
Claim 3
Dependent Claim
32 words
A mechanism as recited in claim 1, wherein the first and second control devices are hydraulically pressure devices mounted respectively in one of the arms of the first and second quadrilateral arrangements.
Claim 4
Dependent Claim
26 words
A mechanism as recited in claim 2, wherein the operating lever is fixed to one arm of the first quadrilateral arrangement adjacent the first control device.
Claim 5
Dependent Claim
94 words
A mechanism as recited in claim 1, wherein the second quadrilateral arrangement comprises, a first arm solidly fixed to the fourth arm of the first arrangement which is rotatably mounted about its longitudinal axis; a second arm opposite the first arm of the second arrangement and invariably spaced relative to the first arm of the first arrangement; a third arm extending between the first and second arms of the second arrangement and including the second hydraulic pressure device; whereby a transverse pivoting movement of the controllable lever longitudinally varies the second hydraulic pressure device.
Claim 6
Dependent Claim
99 words
A mechanism as recited in claim 4, wherein the second arrangement is mounted so as to rotate about its fourth arm, and a third hydraulic Pressure device is mounted between a stationary member and one arm of the second arrangement so that the rotation of the latter arm longitudinally varies the length of the third hydraulic pressure device, means for hydraulically connecting the said third hydraulic pressure device to a third motion actuating system perpendicular to the said orthogonal movement actuating system, whereby a vertical movement of the controllable lever varies the length of the third hydraulic pressure device.
Claim 7
Dependent Claim
60 words
A mechanism as recited in claim 1, wherein the means for connecting the hydraulic pressure devices to the orthogonal movement actuating system comprise a valve assembly and fluid conduit means for hydraulically connecting the said assembly to the hydraulic pressure devices, and the orthogonal movement actuating system comprises power hydraulic cylinders, each power cylinder being actuated by the valve assembly.
Claim 8
Dependent Claim
35 words
A mechanism as recited in claim 6, wherein a lever-positioning hydraulic cylinder is mechanically actuated by each power cylinder and hydraulically connected to the said conduit means for controlling the position of the operating lever.
Claim 9
Dependent Claim
88 words
A mechanism as recited in claim 2, wherein each hydraulic pressure device comprises two tubular containers mounted one inside the other and having a liquid therein, a piston axially movable in the inner container for dividing the said inner container into two chambers, one chamber having a liquid inlet and the other chamber having a liquid outlet, the said inlet and outlet being hydraulically connected to the said actuating system, and each chamber has a release valve and a check valve communicating the same with the outer container.
