Definitions

  • the present invention relates to a hanging device for a harness.
  • this fastening device comprising a support plate and a fastening element intended to retain a connecting element, integral with the rigging, constituted by a rope, the two ends of which are moored to an element of the rigging, such as the "wishbone", so as to form a loop which can be engaged in the hooking element.
  • the latter is generally open downwards and forms an angle allowing good maintenance of the connecting element.
  • the connecting element makes an angle of about 80 ° relative to the axis of the user's body and, when the latter is drawn into a fall, the direction of the 'connecting element varies, approaching the axis of the body of the user.
  • French patent 2,513,333 describes a device for automatic opening of the hooking element, but this device allows the opening of the hooking element only when the tension of the connecting element on the element d the snap is released.
  • US Patent 4,378,614 describes a fastening element which opens automatically, an elastic retaining force allowing this opening when the tension exerted by the connecting element exceeds a certain threshold. This device requires an increase in the force exerted on the fastening element to cause it to open, this opening not occurring by a change of direction of the connecting element.
  • the present invention aims to remedy these drawbacks by providing a device for retaining and releasing the connecting element not only as a function of a threshold of the tension force exerted on the fastening element, but also by function of a torque threshold exerted on the fastening element, this device taking into account the variation of the lever arm according to which the tension force, possibly constant or decreasing, is exerted on the fastening element, variation which results from the change in orientation of the connecting element in the latching element, and by providing an automatic return device in the latching position of the latching element.
  • the attachment device which is of the aforementioned type comprising a support plate integral with a harness linked to the trunk of the user and on which a coupling element is articulated, is characterized in that it comprises, on the one hand, a fastening element having a configuration such that the tension force exerted by the connecting element on the fastening element uses lever arms which increase when the angle made by the direction of the tension force with the axis of the user's body decreases and, on the other hand, a retaining means and a means of automatic return acting on the rotation of the fastening element, the retaining means acting so that the release of the connecting element takes place as soon as the moment of the tension force exerted by the element of connection becomes greater at the moment of the force exerted essentially by the retaining means and this, without there necessarily being an increase in the tensile force thanks to the increase in the lever arm due to the configuration of the element d 'latching, the automatic return means acting so that the latching element returns to the latching position after the connecting
  • the triggering of the retaining means therefore not only results from exceeding a tension threshold exerted by the connecting element, but also from an increase in the lever arm exerted by the connecting element, as a function of its displacement. on the fastening element during a fall or during a voluntary opening. This avoids the drawbacks linked to the fact that the release takes place only by an increase in the force which exceeds the threshold, implying, moreover, a delicate adjustment.
  • the fastening element comprises a central part or hub of circular shape, the center of which has a bore for the passage of a hinge pin, this central part extending by a latching lug which successively comprises on its internal face, starting from the hub, a so-called connection zone, a so-called trigger zone, a so-called latching zone and a so-called evacuation zone.
  • connection area is an area in which the connecting element is never intended to bear. This zone is used to connect the trigger zone to the central part.
  • the attachment zone is the zone on which the connecting element is supported during the current use of the device. This area has a configuration such that, when the connecting element moves over this area, the lever arms vary only slightly, so as not to cause untimely stalling. The attachment element therefore remains in the closed position. When the connecting element moves and passes over the triggering zone or the evacuation zone, the lever arms increase so that the opening of the hooking element occurs.
  • the retaining means according to a torque threshold is constituted by a contact guided by a guide member and constantly subjected to the action of an elastic means associated with it, the contact member, being in the closed position, partially engaged in a recess formed in a part of a part linked in rotation to the hooking element.
  • the contact member and the elastic means consist respectively of a cylinder with an axis parallel to the axis of rotation of the fastening element and a spring, the cylinder, located at the end of the spring being guided by a guide piece and the cylinder-spring assembly being housed in a well drilled in the support plate and emerging, at one of its ends, in line with a part linked in rotation to the attachment element and in which the recess is formed in which the cylinder is partially engaged when the attachment element is in the closed position, the well comprising, in addition, at its other end, an axially movable member such as a screw cap on which the spring rests.
  • the spring exerts a pressure tending to apply the cylinder against the part linked in rotation to the hooking element, so that, in the closed position of the latter, the cylinder partially engages in the recess formed in this piece.
  • the rotation of the fastening element will therefore only be possible if there is sufficient torque on it so that the spring can no longer oppose the ejection of the cylinder from the recess.
  • This torque constitutes the threshold from which the release of the fastening element takes place.
  • the screw cap allows this threshold to be adjusted to the desired value, by modifying the compression of the spring.
  • the automatic return means may consist of a contact member guided by a guide member and constantly subjected to the action of an elastic means associated with it, the contact member being in abutment against a cam profile surface formed in a part of a part linked in rotation to the hooking element.
  • This return means can be similar to the retaining means of the hooking element, that is to say that its contact member is constituted by a cylinder whose axis is parallel to the axis of rotation, this cylinder, guided by a guide piece, surmounting a spring, the assembly being located in a well drilled in the support plate and emerging, at one of its ends, in line with a part linked in rotation to the attachment element, part in which a groove is formed against the bottom of which the aforementioned cylinder is applied, this bottom having a cam profile such that the distance between the cylinder and the axis of rotation of the fastening element is minimum when the fastening element is in the closed position and increases when a rotation of this element takes place.
  • the spring which constantly pushes against the cylinder, tends to bring it closer to the axis of rotation.
  • the force thus created therefore tends to return the fastening element to its initial position when the tension exerted on it by the connecting element ceases.
  • this device is provided with stops limiting the pivoting of the hooking element between a closed position in which the contact member is engaged in the recess intended to receive it and a maximum open position in which the contact member is still in abutment against the bottom of the groove in cam profile.
  • the retaining means and the means for returning the hooking element consist of a single cylinder-spring assembly, possibly provided with an adjustment means, the recess and the groove having a bottom in cam profile. being located on the same diametral plane of the part of the part linked in rotation to the fastening element so that, in the closed position of the fastening element, the recess is opposite of the cylinder and that, during the rotation of the fastening element, the latter is in abutment against the bottom of the groove.
  • the spring no longer resists the thrust of the cylinder which leaves the recess and comes into contact with the bottom of the groove in cam profile. which tends to move it away from the axis of the part linked in rotation to the latching element, thereby increasing the compression of the spring which tends to return the latching element to its initial position.
  • the recess and the groove are formed in the thickness of the hub of the hooking element.
  • the latter is no longer necessarily linked in rotation to its articulation axis, which simplifies the production of the device, avoiding the use of a blocking piece such as a pin or the like intended to make them integral, as is necessary when the recess and the groove in cam profile are formed on this axis.
  • FIG. 1 shows the device according to the invention in use by a windsurfer.
  • This device consists of a support plate 1 on which a hooking element 2 is articulated.
  • the support plate 1 is linked to the user's trunk by a harness and is positioned approximately between his pelvis and his sternum.
  • a connecting element 3 constituted by a rope whose two ends are moored to an element of the rigging such as the "wishbone", so as to form a loop .
  • the user can thus hang under the sail, counterbalancing, by its weight, the force exerted in it by the wind, the harness making it possible to distribute this force over the whole of the trunk and to relieve, thus, the muscular efforts provided.
  • FIG. 2 represents the support plate 1 provided with the hooking element 2.
  • the support plate 1 of curved shape, comprises, at its ends, openings 4 and a central part, the thickness of which is increased, which has two legs 5 provided with bores 6 to form a yoke 7 in which the hooking element 2 is articulated by means of an axis 8 carried by the yoke 7.
  • the articulation of the fastening element 2 is intended to allow the release of the connecting element 3.
  • the openings 4 allow the support plate 1 to be fixed to the harness.
  • the support plate 1 has a length and a curvature close to the width and the curvature of the abdomen of the user in order to make this device comfortable.
  • Figure 3 is a view of the hooking element 2 articulated in its yoke 7 formed in the support plate 1, element having, on the one hand, a central part or hub 9 of rounded shape, comprising a bore in which is engaged the hinge pin 8 and, on the other hand, a lug 10 secured to the hub 9: and bent so as to hold the connecting element 3 against its internal face.
  • the internal face of the latching tab 10 comprises several zones which are, successively and from the hub 9 a connection zone 10a, a triggering zone 10b, a latching zone 10c and a discharge zone 10d.
  • the connection area 10a is an area in which the connecting element 3 is never intended to bear.
  • This zone 10a makes it possible to connect the triggering zone 10b to the central part 9.
  • the triggering zone 10b is the zone on which the connecting element 3 is intended to bear when the connecting element 3 approaches the axis of the user's body, when the latter is driven forward by the rigging or when it voluntarily causes the connection element 3 to drop out by providing a force such as a rotation of the pelvis.
  • the lever arms used by the tension force which evolves from the attachment zone 10c towards the connection zone 10a are larger and larger in order to cause a quick and effective detachment of the element link 3.
  • the attachment zone 10c is the zone on which the connection element 3 is supported during the current use of the attachment device, that is to say when the direction taken by the element link 3 is about 80 ° from the axis of the user's trunk.
  • the lever arms used by the tension force are substantially the same length so that the connecting element 3 can change direction slightly without causing a significant increase in the lever arms which could cause the opening of the attachment element 2.
  • the evacuation zone 10d follows on from the attachment zone 10c; its role is to extend the latch 10 in order to properly hold the connecting element 3 inside the latch element 2. In this evacuation zone 10d, the lever arms which are used by the tension force are increasing in order not to hinder the evacuation of the connecting element 3 when the fastening element 2 opens.
  • the shape of the fastening element 2 is such that, in the open position, the ejection of the connecting element 3 is possible. Furthermore, the yoke 7 comprises a stopper 18 in the position of maximum attachment of the latching element 2.
  • Figures 4, 5 and 6 show the retaining means A and automatic return B which is provided with the device.
  • these means may be identical and consist of a ball or, preferably, a cylinder 11 surmounting a spring 12, separated by a guide means 13 of the cylinder 11, the axis of the cylinder 11 being parallel to the articulation axis 8, that is to say transverse to its direction of movement under the action of the spring 12.
  • Each cylinder 11-spring 12 assembly is placed in a well 14 dug in the thickness of the support plate 1 and of the legs 5 of the yoke 7 emerging, by one of its ends, in line with the axis 8. The other end of the well is closed by a screw cap 15 against which the spring 12 rests.
  • a recess 16 which is opposite the cylinder 11 of the retaining means A when the fastening element 2, in which the connecting element 3 is held, is in position closing.
  • a groove is provided, the bottom of which has a cam profile 17 against which the cylinder 11 of the return means B bears.
  • a pin 19 rotatably secures the axis 8 and the latching element 2.
  • the restoring force of the fastening element 2 is low and can only act after the release of the connecting element 3.
  • the ejection of the cylinder 11 from the retaining means A outside the recess 16 exerts no restoring force on the latching element 2, the release of the connecting element 3 takes place suddenly, as soon as the torque threshold is exceeded.
  • Figure 7 shows an alternative embodiment of the device according to the invention.
  • the axis 8 comprises, in the same diametral plane, the recess 16 and the groove 17 whose bottom is in cam profile. Therefore, a single cylinder 11-spring assembly 12 is necessary to successively carry out the retaining and return functions.
  • the cylinder 11 is partially engaged in the recess 16 from which it is expelled during the rotation of the fastening element 2, to come into contact with the groove 17 in cam profile.
  • a pin 19 rotatably secures the axis 8 and the attachment element 2.
  • FIG. 8 represents a preferred embodiment of the attachment device according to the invention.
  • the recess 16 and the groove 17 in cam profile are formed in the outer peripheral edge of the hub 9 of the hooking element 2.
  • the hub 9 is further provided with a tab 22 intended to come into the position for closing the attachment element 2, in abutment against the wall 20 of the support plate 1.
  • the yoke 7 of the attachment element comprises a wall 18 against which the base of the external face of the latching lug 10, when the latching element 2 is in the maximum open position.
  • the contact member 21 has a hemispherical or semi-cylindrical upper part in contact with the recess 16, this member comprising at its base a bore in which the end of the spring 12.
  • the contact member 21-spring 12 assembly is located in the same vertical plane as the fastening element 2 and the contact member 21 is in line with the recess 16 and the groove 17 according to the angular position of the hooking element 2, in the same manner as previously described.
  • This variant has the advantage of not requiring a fastening in rotation of the fastening element 2 and the axis 8, which simplifies the manufacture of the device.
  • the axis 8 can be of smaller diameter and the tabs 5 no longer having to contain the well or wells 14, can be of smaller dimensions, the well 14 being located in the same vertical plane as the fastening element 2 , that is to say between the two legs 5. This arrangement makes it possible to significantly reduce the size of the device.
