    The invention relates to a removable mooring device intended to be fixed in a hole or borehole, and which can be easily dismountable and recoverable, said device comprising: a first part fixed to expansion head, a second movable control part having jamming means cooperating with the end head to lock or unlock inside the borehole, and a gripping button connected to the jamming means by rods or maneuvering cables, and a spring biasing the jamming means in the blocking direction.
    State of the art
    From the prior art, removable mooring devices can be inserted and extracted without tools in a drilling of a wall of rock or concrete. The extraction is generally performed by pulling on an unlocking control, which causes the escape of the jamming means of the expansion head. EP 2909488 relates to a removable expansion anchor having a rigid stud structure, and US 6729821 relates to a flexible cable anchor. These two types of known mooring devices each have a gripping button, whose recoil against a spring ensures the release for the establishment in the borehole, and its extraction. In the absence of actuation of the gripping button, the blocking is automatically restored following the thrust of the spring. The resulting expansion effect provides effective blocking, which is enhanced by the weight of the load or suspended user. It is otherwise empty, that is without suspension weight on the mooring. It is then sufficient to pull on the grip button with a moderate effort to overcome the force of the spring, and extract the device from its drilling without further deliberate action.
    US 4506924 and 2002/0098054 disclose docking devices having wedge-shaped wedging means cooperating with the expandable end head.
    OBJECT OF THE INVENTION The object of the invention is to provide a removable docking device having an additional function confirming the blocking in the state implanted in the borehole. The apparatus according to the invention is characterized in that the button gripper is associated with a stopper arranged on the first fixed part), said button and stop being movable relative to each other by a relative translational movement to inhibit in a predetermined position any release control.
    Preferably, the gripping button is adapted to occupy a first axial position of offset adjustment of the stop stop to indicate the unlocked state allowing the release control, and is movable to a second axial adjustment position in engagement against the stopping stop to indicate the locked state and inhibiting said unlocking command.
    The light is invisible in the second axial position, indicating the locked state in which the two half-rings can no longer back on the expansion head, and lose contact with the inner wall of the borehole. To return to the unlocked state, it is imperative to manually move the grip knob back to the first setting position in the opposite direction. A specific manual action is therefore necessary on the part of the user to lock and unlock the device.
    According to a first preferred embodiment, the wedging means comprise at least two half-rings driven by the operating rods integral with a drive sleeve, on which is mounted the handle button. The stopper is arranged at the end of an extension of the first fixed part and facing the grip button. The gripper includes a tapped axial bore which cooperates with a conjugate thread provided on the drive bushing to move said gripper button between the first and second adjustment positions.
    Advantageously, the stopper is provided with an axial collar having a colored cylindrical lateral surface to constitute a light indicating when it is visible, that the docking device is in an unlocked implanted state.
    Preferentially, the translation displacement of the gripping button between the two axial adjustment positions occurs by rotating said knob in the direction of screwing or unscrewing according to the type of screw thread adopted for the threading.
    According to a second embodiment, a removable mooring device has a flexible structure in which the first fixed part comprises a cable terminated by the expansion head. The gripping button of the second movable part is axially adjustable to cooperate in the locked state with the fixed stop of the cable.
    The removable docking device according to the present invention is advantageously applicable to climbing, caving and work at heights.

    Description of two particular embodiments
    With reference to FIGS. 1A, 1B and 2-5, the removable safety anchoring device 10 according to the present invention is configured to be fixed in a borehole 11 or cylindrical hole previously drilled in a wall of rock or concrete so as to to safely support a person or a load in suspension. After use, the docking device 10 must be easily dismountable and recoverable by extraction from the borehole 11.
    The docking device 10 is composed of a first rigid bolt-shaped fixed portion 12A with frustoconical expansion head 13 insertable in the borehole 11, and a second movable control part 12B, which is equipped with These half-rings are intended to cooperate in translation with the frustoconical lateral surface of the end head 13 to cause the locking or unlocking of the device in a zone expansion inside the borehole 11.
    The first fixed part 12A comprises an axially elongated barrel 16 of cylindrical section. The rigid barrel 16 is extended towards the frustoconical end-end 13 by a narrowing 17 in which the expandable half-rings 14, 15 extend coaxially. The barrel 14 is provided with an annular support abutment 18 and a stop member 19 on which is mounted a mooring plate 20 serving as a means of suspension. The plate 20 is supported on the apparent face of the wall outside the bore 11, but the entire portion of the barrel 16 between the plate 20 and the end head 13 is pressed inside the bore 11.
    The barrel body 16 is additionally provided with two diametrically opposite longitudinal grooves 21, 22 in which sliding rods 23, 24 are slidably engaged to actuate the two half-rings 14, 15 of the second control portion 12B between a wedge position during expansion and unlocking position. From the abutment abutment 18, and opposite the end head 13, the barrel 16 is extended by a cylindrical intermediate section 25 of diameter smaller than that of the barrel 16, and on which is threaded a spring of compression 26 with helical turns.
    The translational movement of the operating rods 23, 24 with the expansion half-rings 14, 15 is effected manually by means of a gripping button 27 extended by a tubular end 28. The diameter of the gripping button 27 is greater than that of the end piece 28, which coaxially surrounds a bushing 29 for driving the operating rods 23, 24. At the opposite end of the half-rings 14, 15, the operating rods 23, 24 have fasteners 30, 31 fixed in an annular groove 32 of the drive sleeve 29.
    The compression spring 26 extends inside the tubular sleeve 29 so as to urge it in axial translation towards the right against the abutment stop 18 of the barrel 16 (FIG. 2), and in the direction of engagement. half-rings 14, 15 on the frustoconical end-piece 13. The gripping button 27 and the nozzle 28 are traversed by a tapped axial bore 33, which cooperates with a threaded thread 34 provided on the outer lateral surface of the drive sleeve 29.
    A stopper 35 is fixed on an axial extension 36 end of the intermediate portion 25 of the first fixed portion 12A to limit the travel in translation of the gripping button 27 mobile. The diameter of the axial extension 36 is smaller than that of the section 27. The stopper 35 is provided with an axial flange 37 having a cylindrical lateral surface colored red to form a sighting indicator 38 when it is visible, that the mooring device 10 is not locked in the borehole 11.
    The operation of the removable docking device 10 according to the invention is as follows:
    In FIG. 2, the docking device 10 is in the initial state, that is to say not sunk in the borehole 11. The gripping button 27 is inactive and axially offset from the fixed stopper 35 by an axial distance d. The tip 28 for driving the operating rods 23, 24 is held against the bearing abutment 18 by the action of the spring 26 compression. The two half-rings 14, 15 are engaged on the frustoconical end-piece 13 of the barrel 16. In this initial state, any depression of the anchoring device 10 in the borehole 11 is made impossible following the presence of the half-rings. 14, 15 on the end of the cone.
    In Figure 3, the docking device 10 is ready to be inserted in the borehole 11 following the retreat of the gripping button 27 against the fixed stopper 35. The sleeve 29 moves back with the handle 27, and drives the operating rods 23, 24 in the same direction (arrow F1), as well as the half-rings 14, 15 which leave the frustoconical end-piece 13 while positioning itself. in the narrowing 17 of the barrel 16. The large end base of the frustoconical head 13 has a diameter slightly smaller than the diameter of the bore 11, which allows the axial insertion of the barrel 16. The compression spring 16 is compressed during the movement of the barrel. back of button and socket 29.
    Figure 4 shows the docking device 10 in the unlocked implanted state. The plate 20 bears on the outer wall with a maximum depression of the barrel 16 in the borehole 11. After release of the gripping button 27, the spring 16 expands and pushes the two half-rings 14, 15 towards the cone of the head end 13 to the point of contact with the inner wall of the borehole 11. The resulting expansion effect provides effective blocking, which is reinforced by the weight of the load or user suspended from the plate 20. But in the absence of weight on the wafer 20, a possible traction exerted on the gripping button 27 allows an immediate release and makes possible the extraction of the docking device 10. The red indicator 38 is visible, which indicates that the docking device 10 is not locked in the implanted state. In this unlocked state, the gripping button 27 occupies a first setting position on the section 25, with a predetermined axial offset with respect to the stopper 35.
    In Figure 5, the docking device 10 is in the locked implanted state. The transition from the unlocked implanted state to the locked implanted state is effected by bringing the gripping button 27 closer to the stop stop 35. The gripping button 27 then occupies a second adjustment position set back from the first position, so as to come into engagement with the stopper 35, thereby to inhibit any unlocking movement of the second control portion 12B. The red light 38 becomes invisible in this second axial position, indicating the locked state in which the two half-rings 14, 15 can no longer move back on the cone of the end head 13, and lose contact with the inner wall of the drilling 11. For the return to the unlocked state of FIG. 4, it is imperative to manually shift the gripping button 27 in the opposite direction to the first adjustment position, with the formation of a certain axial offset with respect to the fixed stopper 35, allowing unlocking and extraction of the docking device 10.
    The translational movement of the gripping button 27 between the two axial adjustment positions is effected by rotating the knob 27 with the end piece 28 in the direction of screwing or unscrewing according to the type of thread chosen for the thread 34. case of the previously described figures, the pitch of the thread 34 is on the left, which makes it possible to screw the gripping button 27 to ensure the locked state of FIG. 5.
    If the pitch of the thread 34 is on the right, it will be necessary to unscrew the gripping button 27 to bring it into the locked state towards the second adjustment position in contact with the stopper 35.
    Such a screw adjustment system is particularly advantageous because it makes it possible to obtain the locked state, independently of the diameter of the borehole 11, since the second control part 12B can stop at different places.
    It is of course possible to ensure the relative displacement in translation of the gripping button 27 and the stopper 35 by any other equivalent mechanical system to prohibit unlocking in the locked implanted state of the docking device 10. just have two stops, one on the first fixed portion 12A, and the other on the second control portion 12B, and move the two stops relative to each other to inhibit the control deblocking dabs the lock state.
    In the case of rigid operating rods 23, 24, the inhibited displacement of the second control portion 12B in the locked state also causes a compression effect of the operating rods on the half-rings 14, 15 for a reinforcement of anchoring.
    The variant embodiment of FIGS. 6 and 7 shows a flexible detachable mooring device 100 in place of the rigid mooring device 10 of FIGS. 1A, 1B and 2-5. The same reference numbers will be used to designate similar parts, but assigned to the hundred.
    The first fixed part 112A is constituted by a cable 116 of high resistance instead of the metal drum 16, one end of the cable 116 being shaped loop attachment 120, and the other end being equipped with a head expansion, in particular frustoconical 113.
    The second movable part 112B comprises a gripping button 127 intended to move two half-rings 114, 115 cooperating in translation with the frustoconical head 113. In place of the rigid operating rods, control cables 123, 124 are used to connect the half-rings 114, 115 to the gripping button 127. A compression spring 126 is arranged around the cable 116 between the gripping plunger 127 and a stopper 135 fixed on the cable 116.
    Unblocking occurs in a conventional manner by pulling on the gripping button from a first axial adjustment position in the direction of the arrow F2 (Figure 6) until it comes into engagement against the stopper 135 The half-rings 114, 115 move away from the frustoconical end-end 113 and allow insertion into the borehole.
    To lock the docking device 100 once implanted in the borehole, the gripping button 127 is positioned, for example by screwing or unscrewing along a sleeve 129, towards a second adjustment position against the stopper 135 (Figure 7). Any unblocking movement becomes impossible, and the docking device 100 is maintained in the locked implanted state. To unlock, it will be necessary to return the grip button 127 to the first adjustment position of FIG. 6, which is offset axially from the stopper 135.
    According to another variant, the wedging elements may be formed by cams or wedges. The expansion head may have any shape depending on the type of jamming means. The invention applies to any other type of removable mooring requiring to be locked after installation.
