Definitions
- the present invention relates to a device for gripping and tensioning adjustment of an elongated element of cable, rope or similar type.
- the present invention relates to a device for gripping and adjusting the tension of an elongated element, for which, with the same device as for its gripping, a tensile force exerted on the elongated element makes it possible to perform its tensioning, the tension imposed on the elongated element being also to some extent adjustable while maintaining gripping this element.
- This gripping is achieved conventionally using jaws or a jaw that close on the elongated object. It is also known to use at least one means for actuating the jaws or jaws, in particular at least one jack, to carry out this gripping operation.
- a gripping device is traversed longitudinally in its median part by the elongate element and has, in general, in the direction of its length a rear body extended by a transverse front clamping assembly to the device on said elongate member intermediate jaws at least partially surrounding said element.
- These jaws are disposed inside said assembly before being movable longitudinally in said front assembly under the action of at least one actuating means.
- the front assembly has at least one jaw guide system for approximating the jaws for gripping said member within said assembly, the distance between jaws decreasing with advancing forwardly in said set.
- the document GB-A-190928294 discloses a cable or rope locking system using at least one jack, and an inclined plane for making the approximation or removal of two gripping portions, each being secured to a jack.
- the object of the present invention is to simplify the existing gripping devices of an elongated element while also enabling them to tension the elongated element with the possibility of adjusting it.

- the technical effect obtained by the present invention is to make it possible to achieve, in particular by using the same jack or by using more than one jack in operation. simultaneous and synchronized, two successive phases namely a gripping followed by an adjustable tensioning of the elongated element.
- the device according to the present invention has the advantage of being considerably less complex than the combination of devices of the state of the art providing gripping with a voltage control device of the element, in particular by being able to involve the participation a reduced number of cylinders.
- the device according to the present invention thus has the advantage of allowing, by a single device, a voltage adjustment of the elongate object while keeping it gripped, this without necessarily resulting in particular control means for the implementation of these two phases.

- the stop represents in fact a simple embodiment of the securing means.
- the stop is in the form of a stop plate removably disposed at the front portion of the assembly before tightening.
- the shape and the removable nature of this stop plate are advantageous because they allow easy replacement of the plate to possibly adapt to the different forms of jaws used or to remedy its wear.
- the assembly before tightening comprises two bases disposed symmetrically with respect to its longitudinal axis, each of the bases being associated with a jaw and at least one base having an internal wall forming a ramp for sliding a jaw on it while being inclined towards the longitudinal axis of the front assembly in the forward direction of said assembly, said inner wall forming part of the guiding system of a jaw.

- This figure shows an embodiment of the sliding between, on the one hand, the jaws 3 relative to the associated sliding bases 1 and 5 and, on the other hand, the lower sliding base 5 relative to the mounting base 7 to the supporting structure.
- These various sliding movements are made possible by the presence of a sliding means and / or specific lateral retention for each sliding, said means being illustrated by a dovetail connection 19 between the aforementioned elements.
- the movable front clamp assembly 101 formed mainly of the bases 1 and 5 may have on each of its lateral sides a lateral closure plate 2 at least partially covering said sides.
- Each of the closure plates 2 is detachably secured to one of the sliding bases 1 and 5 by removable fixing means 6a, for example a screw penetrating into a threaded blind hole 1 1 common to a sliding base 1 or 5 and to an associated lateral closing plate 2.
- a safety device To prevent a bad maneuver from releasing the elongated element by mistake at the moment when the assembly before 101 clamping is in contact with the front face of the cylinder, it can be provided a safety device. Similarly, it can also be provided a safety to prevent the assembly before 101 movable tightening leaves the front face of the cylinder before the jaws 3 are in abutment against the front stop plate 9.
- the present invention can apply to all areas, where it is necessary to grip an elongated element, both metallic and other, this element can be of greater or lesser section and proceed to its tensioning . It can for example find an application in combination with a winch, for example a hydraulic winch.
- a particularly interesting but not exclusive application of the device for gripping and adjusting the tension of an elongated element is its association with a boat as a supporting structure, for example a sailboat.
- a device is then mainly used as attachment equipment, fixing and adjustment of the current rigging as that of the standing rigging and maneuvers.
