Definitions

  • the present disclosure relates to a portable tool configured to ensure the expansion of a dowel (of a screw and dowel assembly).
  • HWA Hollow Wall Anchor
  • Molly anchor typically metallic
  • the expansion of the anchor is not allowed by screwing the screw, but requires a specific tool, namely an expansion control pliers well known in the state of the art.
  • the clamp mechanism thus has two parts, movable relative to each other, namely a fixed part and a slide pressing respectively against a shoulder of the ankle and the head of the screw, and allowing the spacing of the screw head relative to the shoulder of the dowel when moving the slide, to cause expansion of the dowel.
  • the pliers conventionally comprise a handle, with a fixed branch and a movable branch, which when driven towards the fixed branch, makes it possible to cause the movement of the slide by a given pitch, and thus to separate the head of the screw from the ankle shoulder.
  • the stroke required for expansion of the ankle is not a fixed value and depends on the model of the ankle: with such a clamp, optimal expansion of the ankle may require several presses on the handle to cause several consecutive movements of the ankle. slide (from the given pitch) to the desired stroke.
  • Some expansion control pliers include an adjustment system that allows you to control the stroke, by controlling the number of presses on the handle and therefore the number of steps.
  • this type of pliers however has the disadvantage of requiring a large number of presses on the handle to install the dowels, which can lead to musculoskeletal disorders for the operators.
  • the expansion control pliers on the market have insufficient slide travel to ensure optimal expansion of the dowel, even with several successive presses on the handle.
  • expansion of the ankle may require a two-stage installation procedure, i.e., first using the pliers to move the screw head away from the shoulder of the ankle while performing an initial expansion , but only partial of the ankle.
  • the operator disengages the clamp from the dowel, to proceed to screwing the screw, and thus bringing the head of the screw closer to the shoulder of the dowel, before re-engaging the expansion control pliers to ensure the desired expansion during a second use of the pliers.
  • This disclosure improves the situation.
  • the user interface is a rotary adjustment wheel.
  • the adjustment wheel can be integral with the rotary axis of a potentiometer, the control module comprising the motor card connected to the terminals of the potentiometer and associating different values of the variable resistor at the terminals of the potentiometer with different values of the stroke determined.
  • the value of the stroke is adjustable over a range which extends to at least 44 mm for the value of the determined stroke.
  • said user interface ensures the adjustment of the value of the stroke determined according to an adjustment increment less than or equal to 3 mm, preferably less than or equal to 2 mm, or even less than or equal to 1 mm.
  • the transmission between the rotor of the electric motor comprises a screw/nut system, configured to transform the rotational movement of the motor rotor into a translational movement of the slide.
  • the tip comprises a barrel terminated at its distal end by the first support, and connected at its proximal end to a body of the tool, said body carrying the motor, or even a reduction gear as well as the module of control, and in which the tubular barrel comprises a housing forming a slide for the slide, with blocking the rotation of the slide relative to the barrel around a longitudinal axis of the barrel.
  • the screw of the screw-nut system extends internally to the barrel, guided in rotation by a bearing such as a bearing, connecting the screw and the wall internal of the barrel, and said nut is mounted movable in translation inside the housing, without the possibility of rotation of the nut relative to the barrel around a longitudinal axis of the barrel.
  • the tip and the body of the tool comprise removable fixing means between the proximal end of the barrel and the body of the tool, comprising for example a retaining ring and in which the end of the screw at the proximal end of the barrel, on the one hand, and the output of the reducer from the body of the tool, on the other hand, comprise complementary coupling parts by interlocking, removable ensuring torque transmission .
  • the user interface is located on the rear part of the body of the tool, diametrically opposite to the tip connected to the front part of the body of the tool.
  • the tool comprises a handle, and in which said control member is a trigger configured to be pressed by a finger such as the index finger of the hand gripping the handle.
  • the energy source of the motor and the control module is a battery, possibly provided removable relative to the body of the tool.
  • the present disclosure relates to a portable tool 1 configured to ensure the expansion of an expansion dowel Ch of a screw Vs and dowel Ch assembly, such as a Molly dowel.
  • This shoulder Ep is intended to come to bear on a first face of a wall through which the pin is inserted and as illustrated in Figure 6 . Claws can be provided on the shoulder to bite the wall.
  • the ankle further comprises a plurality of branches Bv each connecting the nut Ec to the shoulder Ep.
  • the expansion of the ankle is obtained by deformation of the branches, in particular folding of the branches, ensuring the rimpedement of the shoulder Ep with the nut Ec, which is itself obtained by separating the screw head Tv from the shoulder Ep, and as illustrated by way of example in Figure 6 .
  • the tool also comprises a drive mechanism configured to move the slide 24 from a first initial position P1, for which the second support 25 is juxtaposed to the first support 21.
  • This first initial position authorizes the insertion of the screw through the first and second notches 22,26 then facing each other and juxtaposed, with the first support 21 coming into contact against the shoulder Ep of the expansion anchor Ch inside which the screw Vs is screwed.
  • the threaded part of the screw then passes through the first notch 22 and the second notch 26 juxtaposed.
  • the screw head Tv of dimension greater than the second notch 26, is then positioned opposite the second support 25, and capable of being pulled by the second support 25 when the slide 24 separates the second support 25 from the first support 21. In this position, the second support 25 is positioned intermediate between the first support 21 and the screw head Tv.
  • the drive mechanism is configured to move the slide 24 from said first position P1 to a second position P2x; P2y for which the second support 25 then in contact against the screw head is moved away from the first support 21 in contact with the shoulder Ep of the ankle, by sliding of the slide 24 along the slide 23.
  • This movement causes the spacing of the screw head Tv of the shoulder Ep of the dowel, and thus the expansion of the dowel Ch by deformation of the branches Br under the approximation of the nut Ec and the shoulder Ep.
  • the drive mechanism comprises an electric motor M comprising a rotor 27 and a stator, as well as a transmission ensuring the movement of the slide 24 along the slide 23 during rotation of the rotor, as well as a control module 30 comprising a control member 28.
  • This control module is configured, when the operator presses said control member 28, to actuate the motor in order to drive the slide 24 from the first position P1 towards the second position P2x, P2y.
  • Such a tool ensures the expansion of the ankle in a motorized manner, advantageously reducing the efforts for the user compared to a tool with a (manual) clamp mechanism.
  • control member 28 is an electric button with a normally open switch, pressing on said control member 28 ensuring actuation of the electric motor M, and the release of the control member 28 l stopping the engine.
  • the control member 28 and the switch can be with all or nothing operation, or alternatively advantageously with progressive operation, with control of the variation of the speed of rotation of the motor, in particular as a function of the support stroke on the control body 28.
  • the tool may comprise a handle 40: said control member 28 may be a trigger configured to be pressed by a finger such as the index finger of the hand gripping the handle 40.

  • the motor card CM can be a card with control of the position of the motor, the card ensuring automatic stopping of the motor when the slide reaches the second position P2x, P2y and in particular even when the operator continues to press on the control member 28.
  • the determined stroke is chosen here as a function of the characteristics of the expanding anchor Ch, or even of the support for placing the anchor, in particular the thickness of the wall inside which the anchor is inserted.
  • the determined stroke is chosen in order to obtain the deformation of the branches ensuring optimal support of the ankle.
  • control module 30 comprises a user interface 31 configured to ensure the adjustment of the value x, y of the determined stroke.
  • the user interface 31 can be a rotary adjustment wheel. This adjustment wheel 31 can be integral with the rotary axis of a potentiometer Pt.
  • the control module 30 then includes the motor card CM connected to the terminals of the potentiometer and associating different values x, y of the determined stroke with different values of the variable resistor at the terminals Bn of the potentiometer Pt.
  • the user interface 31 can take other forms such as a digital display with one or more buttons allowing the adjustment of the stroke determined.
  • a digital display with one or more buttons allowing the adjustment of the stroke determined.
  • Such an interface makes it possible to adjust the value of the stroke determined according to the characteristics of the dowel and the support, and according to different dowel dimensions. It becomes possible to ensure optimal deformation of the branches during expansion of the ankle, in a repetitive and reliable manner, and advantageously whatever the ankle model.
  • the adjustment of the determined stroke is preferably a fine adjustment: said user interface 31 ensures an adjustment of the value of the determined stroke preferably according to an adjustment increment less than or equal to 3 mm, preferably less than or equal to 2 mm, or even less than or equal to 1 mm, or even an adjustment of the value of the stroke determined continuously.
  • the stroke of the slide can be at least equal to 44 mm.
  • a stroke of the slide from the first position P1 to the second position P2x, P2y allows the installation and expansion of the dowels available on the market, even the longest.
