Definitions
- Cable control mechanism comprising an elastically deformable member for assisting in the operation of the cable.
- the present invention is in the field of cable control devices of a remote member. It relates to a mechanism of the kind for the operation of a remote hydraulic member, in particular for such a member participating in a hydraulic system at relatively high pressure. It will be recalled that, in general, it is known to remotely control the operation of a hydraulic member, such as a distributor or the like, from a cable control mechanism. Such common mechanisms are known, which implement a control lever articulated on a housing and manipulated by a user, to actuate the cable. Different variants are usually proposed according to the conditions of use of the remote member to be operated, and more particularly according to the hydraulic power against which it is necessary to act to operate the remote member.
- the cable In the context of a relatively low hydraulic power, the cable is directly related to the remote member to be operated. In the context of a relatively high hydraulic power, the cable is in relation to an intermediate member for maneuvering the remote member, this intermediate member making use of an additional power source. More particularly this intermediate member, such as a servomechanism, is interposed between the cable control mechanism, which operates it, and the remote member that the intermediate member operates in turn. It is therefore essential for the user wishing to control a hydraulic member remotely, the choice of the type of control mechanism to be implemented as a function of the hydraulic power at meeting of which the distant organ must be operated. This choice naturally takes into account the costs involved, the implementation of a control mechanism comprising an organ and an additional power source to operate the remote organ, implying a higher installation cost.
- the housing houses the control member, the proximal end of which forms the handle and emerging from the housing in order to be graspable by the user, comprises a grip handle for its operation in mobility between a rest position and at least one working position, in which working position the cable is active against a resistance force exerted by the remote member to be operated.
- the lever is also connected to a cable operating member which is housed inside the housing and on which the cable is anchored, so that in the working position, the cable exerts effective traction on the remote member. .
- the object of the present invention is to provide a mechanism of the aforementioned type described by EP0458313 and FR2678082 for cable control of a remote hydraulic member to be maneuvered, for a civil engineering machine or the like, which makes it possible to maneuver directly from the cable a such a remote member meets a relatively high power, while offering a limited space and a simple structure of the mechanism intended to be housed in a housing, and an ergonomics providing the user with satisfactory ease and comfort of maneuver. It is more particularly targeted by the present invention to provide such a cable control mechanism applicable to a joystick, in which the lever is articulated omnidirectionally for an action of the cable, either for traction or for compression.
- the inventive step of the present invention consisted in breaking with the habits adopted in the field by proposing a cable control mechanism of the aforementioned kind, in which the mobility of the control member housed inside the housing between its passage from its rest position towards a working position, in order to exert on the cable any one at least of a tensile force than of compression, is accompanied by an elastically deformable assistance member constituting with the handle of the member control.
- the lever and the elastic member are abutted to be placed in extension of one another, the lever bearing at its base against the elastically deformable member to keep it under stress in the rest position and to release it in position working against resistance exerted by the distant organ to be operated.
- the control member is composed of at least two butted sections articulated to one another.
- a first proximal section constitutes said lever while a distal section is formed of an elastically deformable member, which takes an articulated support against the housing to constitute a member for assisting in the operation of the lever.
- the assistance member is any one of the members of the group of members comprising the compression springs and the gas cylinders, or the like.
- the assistance member is a gas spring which is articulated at its corresponding bottom and head ends respectively on any one of the housing and of the lever.
- FIG. 1 is a view in longitudinal section along a first transverse plane, of a cable control mechanism according to a preferred embodiment of the invention.
- Fig.2 and Fig.3 are views in longitudinal section along a second transverse plane, orthogonal to the previous, of the cable control mechanism shown in fig.1.
- a cable control mechanism mainly comprises a handle 1 provided at its distal end with a grip handle 2, not visible in fig.2 and fig.3.
- This lever is articulated on a housing 3 and is connected to a cable 4 for the operation of the latter.
- This gas cylinder 5 is articulated in a ball joint 6 and 7 on the lever 1 and on the housing 3, respectively through its bottom end 8 and its head end 9. It will be noted that this arrangement of the gas spring 5 is preferred for limit the risks of bending the rod, but similarly the arrangement of the gas spring is likely to be reversed from one to the other of its ends without departing from the rules of the invention which have been set out.
- the control mechanism is preferably equipped with means for adjusting the stroke of the assistance member 5, which advantageously consist of an arrangement of a support member 10 against the housing 3 of the assistance member 5, in a member for adjusting the distance separating one from the other the ends 8 and 9 of the latter 5.
- this arrangement is constituted by a thread connection, or the like, between the housing 3 and the support member 10.
- the support member 10 emerges from the housing to allow the desired adjustment to be made from outside the housing 3. It will be noted however that in a similar manner but not preferred because of the difficulty of implementing the desired adjustment, equivalent arrangements can be made in the support zone of the assistance member 5 on the lever 1.
- the handle 1 On Fig.3, the handle 1 is in the rest position, that is to say that it exerts no action on the cable 4, both in traction and in particular thrust. It will be noted that in the usual manner in the field, the lever 1 is spontaneously maintained in the rest position by means of immobilization or blocking, not shown in the figures. In this rest position, the lever 1 and the gas spring 5 are arranged in the extension of one another, so that the gas spring 5 is placed under stress in the rod position at least partially retracted. On f ⁇ g.1 and f ⁇ g.2, the handle 1 is in the working position, that is to say that it exerts on the cable 4 a force, pushing or pulling, to directly operate a power member distant, not shown in the figures.
- the handle 1 is moved by the user until it inclines along an axis A2 contributing to the general axis A1 of orientation of the handle in the rest position, in the usual manner in the field.
- This movement of the joystick by the user breaks the alignment between the lever 1 and the assistance member 5, to cause the release of the latter.
- the power then developed by the assistance member 5 is used to exert on the lever 1 a force capable of causing the cable 4 to maneuver against the resistance offered by the remote member, the effort of the user being only then limited to the guiding in position of the lever 1.
