Definitions

  • the invention relates to a rope gripper.
  • rope grippers are used on sailing boats for attaching sheets of sails or the like.
  • the known rope grippers often have one or several disadvantages.
  • the rope gripper is characterised by a flexible sleeve-like clamping element arranged in a stationary housing, through which clam ⁇ ping element the rope to be gripped can extend, said clamping element being deformable between a gripping position in which its both ends are distanced such, that the internal surface of the clamping element due to a transversal contraction thereof grippingly engages the outer surface of the rope to be grip ⁇ ped, and a release position in which both ends are positioned closer such that the internal surface of the clamping element releases the rope for a longitudinal displacement.
  • the clamping element comprises a sleeve of spirally braided threads.
  • the threads are made of steel.
  • the threads of the sleeve extend left-hand spirally as well as right-hand spirally. Due to this spiral shape the rope gripper according to the inven ⁇ tion obtains a high gripping force. As a result of moving apart both ends of the clamping element a transversal contrac ⁇ tion is caused, which in its turn leads to a frictional force exerted onto the sleeve by the rope. Because each thread of the sleeve is wound around the rope to be gripped several times an extremely high force amplification is provided which has as a result that the threads contract the rope even more and that the gripping force is further increased. This means that it is sufficient to provide an initial friction for obtaining an effective operation of the rope gripper according to the invention.
  • one end of the clamping element is positioned stationary in the housing whereas the other end is movable with respect to the housing by means of an actuator element. Moving the clamping element from the release position towards the gripping position and reversed can be realised now in a simple way by moving the movable end of the clamping element relative to the housing using the
  • the actuator element comprises an actuator arm movable with respect to the housing, which actuates the movable end of the clamping element.
  • the housing that is attached to the underground, for example the deck of a sailing boat, then functions as support for the actuator arm.
  • the actuator element engages the movable end of the clamping element via a spring means.
  • the spring means comprises a compression spring which at least partially sur ⁇ rounds the clamping element and which is prestressed between the actuator element and the movable end of the clamping element.
  • the actuator element and the movable end of the clamping element are interconnected through an element which can take up a tensile force.
  • the rope gripper can be moved to its release position by operating the actuating element.
  • the element comprises a bush engaging around the actuator element or a sleeve attached thereto and further engaging around the movable end of the clamping element or a clamping sleeve attached thereto.
  • this bush has no influence whatsoever.
  • a settable abutment for limiting the distance between both ends of the ⁇ lamping element in the gripping position.
  • the abutment cooperates with the mova ⁇ ble, end of the clamping element.
  • the ends of the clamping element each are sandwiched between two tape- ring concentric clamping sleeves.
  • the clamping element can be provided in the stationary housing in a simple way.
  • Figure 1 shows an embodiment of the rope gripper according to the invention, partially in section and in a gripping position
  • Figure 2 shows the rope gripper from figure 1 in its release position
  • Figure 3 shows the principle of sandwiching both ends of the clamping element, as applied in the rope gripper accor ⁇ ding to figure 1 and 2
  • Figure 4 shows a second embodiment of the rope grip ⁇ per in a gripping position
  • Figure 5 shows the rope gripper of figure 4 in its release position.
  • the rope gripper illustrated in figure 1 comprises a housing 1 which> by means of mounting lips 2, 3, is attachable to an underground, for example the deck of a sailing boat.
  • the housing 1 comprises two housing halves 4 and 5 connected to each other at a, mounting partition. Through the house 1 a continuous bore 6 extends in which a flexible sleeve-like clamping element 7 is provided.
  • the clamping element 7 mainly comprises a sleeve 9 of left-hand and right-hand spirally braided threads. In a pre ⁇ ferred embodiment the threads are made of steel.
  • the left-handed end of the clamping element 7 is, via the outer clamping sleeve 10, received in an enlarged section 12 of bore 6 in housing 1.
  • the outer clamping sleeve 10 comprises a corresponding collar 13. Due to the cooperation between the collar 13 and the enlarged section 12 the left- handed end of the clamping element 7 is axially stationary mounted in the housing 1.
  • the opposite movable end 10' of the clamping element is positioned near to an abutment 14 which lets the rope 8 pass and which is positioned in the bore 6 of the housing 1, such that the clamping sleeve 10' is, relative to the housing 1, in axial direction movable to and fro in a limited way.
  • An actuator arm 15 is pivotable around a pivot axis 16 attached to the housing 1. By means of a slot 17 the actua ⁇ tor arm 15 engages with its inner end a pin 18 provided on a sleeve 19. It will be directly understood that pivoting the actuator arm 15 around the pivot axis 16 leads to an axial displacement of the respective sleeve 19 relative to the housing 1.
  • FIG. 4 A different embodiment of the rope gripper is shown in figures 4 and 5.
  • This rope gripper entirely corresponds with the rope gripper described before. The only difference comprises a bush 21 engaging around sleeve 19 and clamping sleeve 10' .
  • this bush operates in the same way as described in respect to the compression spring 20 operating as tensile spring too.
  • displacing the sleeve 19 to the left by means of the actuator arm 15 it carries along bush 21, which on its turn carries along clamping sleeve 10' to the left, which results in the sleeve 9 releasing rope 8.
  • the compression spring 20 does not have to operate as tensile spring and can maintain a certain prestressing. Moreover it is not required then that this spring 20 is atta ⁇ ched to the * sleeve 19 and/or clamping sleeve 10• .
  • the bush 21 in no way whatsoever hinders the gripping operation and has no influence when moving the sleeve 19 and the clamping Sleeve 10' to the right. When moving to the left however it takes care for maintaining the prestressing in the spring 20. * * '*
  • the invention is not limited to the embodiment des- cribed before, r which can be varied widely within the scope of the invention.

Abstract

La présente invention décrit un dispositif pour serrer les cordages composé d'un élément de serrage flexible en forme de gaine (7) par lequel passe le cordage (8). Cet élément peut être étiré jusqu'à se contracter transversalement de sorte que le cordage (8) soit serré par la surface interne dudit élément (7). On étire ce dernier en séparant les deux extrémités. A cette fin, il est préférable qu'une de ces extrémités reste immobile, tandis que l'autre peut être déplacée au moyen d'un élément de commande. L'élément de serrage comprendra de préférence une gaine tressée en spirale (9).
