Definitions

  • the invention relates to a universal screwdriver support for a plate lifting tool, a tool provided with such a support, and a method of implementation.
  • the invention relates to lifting and handling tools, generally called “lifts”, winch or gears used during work, for the manipulation and positioning of heavy objects, such as sheets of materials (plasterboard, wood panels, etc.) to make false ceilings or development under crawling or partitions.
  • lifts winch or gears used during work
  • heavy objects such as sheets of materials (plasterboard, wood panels, etc.) to make false ceilings or development under crawling or partitions.
  • a telescopic mast controllable by a hoist mechanism or gear
  • a plate holder is pivotally mounted to the end of the mat by means of a pivot mechanism.
  • the telescopic mast comprises a first fixed element, and at least one mobile element telescopic with respect to the fixed element.
  • the mast comprises two telescopic movable elements.
  • This type of plate lifter does not allow activation of the winch by a screwdriver. It is therefore exclusively manual and slow.
  • the screwdriver is itself attached to the mast of the lifter.
  • Such lifter comprising a control shaft engaged with a screwdriver is for example disclosed by the document EP2314422 A .
  • the screwdriver acts as a simple motorized mechanism, the use of a screwdriver only to limit the design costs of a battery engine. It is therefore not possible to use a screwdriver. In addition to the very high cost of such a lifter, the constant presence of the screwdriver can clutter the tool and makes it heavy handling.
  • the Applicant has developed a lifter equipped with a gear lifting mechanism. This type of device is particularly interesting because it is quiet and requires less effort to lift plates.
  • Such a lifter is illustrated in figure 1 .
  • control shaft has an end provided with a fixing end for a portable electric screwdriver. It is thus possible to actuate the lifting mechanism by a screwdriver, which limits the efforts to provide.
  • the screwdrivers are very common on construction sites and it is very easy to recharge them.
  • the present invention therefore aims to provide a universal screwdriver support, that is to say, to use different models of screwdrivers currently on the market, allowing safe actuation of the lifting mechanism without risk of injury to the user .
  • the screwdrivers are generally pistol-shaped and include a handle with a motor activation trigger and a motor driven screw / unscrewing shaft.
  • the latter is supplied with energy by a rechargeable battery slid reversibly into the handle. In the use position, the battery is generally in the lower position relative to the hand and constitutes the base of the screwdriver.
  • the figure 1 illustrates a lifter in the position of use, provided with a geared lifting mechanism.
  • the plate lifter 1 comprises a lifting mechanism 100 to which is attached a wheel base 200 and a plate support 300.
  • the lifting mechanism 100 comprises a telescopic mast 10 comprising a fixed segment 11 and a first telescopic segment 12 slidably mounted inside the fixed segment 11.
  • a rack 13 is fixed to the first telescopic segment 11.
  • the rack 13 is engaged with a gear system illustrated in greater detail in FIG. figure 6 .
  • control wheel 23 may be equipped with a crank 231, preferably pivotally mounted on the control wheel.
  • the control shaft passes through the flywheel and has an end provided with a fixing endpiece 232 to a complementary endpiece carried by a portable electric screwdriver. It is thus possible to actuate the lifting mechanism by a screwdriver, which limits the efforts to provide.
  • This embodiment is particularly advantageous because it allows a great transmission power so that neither a user in manual mode, nor the screwdriver do not tire, while ensuring a mast climb speed higher than the speeds generally seen with the throwing plates. the state of the art.
  • control shaft 22 is fixed to the control wheel 23 by means of a unidirectional bearing.
  • this type of bearing if the control shaft 22 is engrained with a portable electric screwdriver, the control shaft 22 can rotate at high speed in the direction of raising the mast without previously driving the steering wheel in rotation.
  • the invention provides a screwdriver support 400 adaptable to the lifter, so as to block the rotation of the screwdriver, and that the motor of the latter transmits all the torque to the control shaft of the lifting mechanism and not to the wrist of the user.
  • the user positions and secures the screwdriver on the control shaft of the lifting mechanism.
  • the fixing member 410 comprises a longitudinal profile 411 provided at one end with a fastening means 412 to the mast 10 and at a second end of two lateral oblong slots 413.
  • the fixing means 412 of the fixing member on the mast advantageously comprises two parallel fixing plates 414 fixed to the fixing member and distant from each other by a distance at least equal to a width of the mast. L M.
  • Each plate comprises at least one hole 415 facing the hole 415 of the other plate, intended to receive a through bolt 416 when the support is positioned on the mast (see Figures 4 and 6 ).
  • the user places the screwdriver support 400 on the mast so that the two fixing plates 414 of the support are arranged on both sides. of the mast.
  • the mast 10 advantageously comprises a rolling base 200.
  • the fixing means of the screwdriver support can be adapted to be fixed to the rolling base of the mast.
  • it can be designed to attach to the winch support when the hoist mechanism is a winch.
  • the fastener may have multiple shapes and the fastener itself may be of different types depending on the shape of the lifter.
  • the fastener allows the maintenance of the screw driver support so that the lateral stop prevents the rotation of the screwdriver during use. In other words, what matters is the lateral locking of the screwdriver.
  • the attachment to the mast may be rigid in a direction perpendicular to the axis of rotation of the control shaft of the hoist mechanism, and free in a direction parallel to the axis of rotation of the hoist shaft. control of the lifting mechanism.
  • the adjusting member 430 is constituted by a jumper placed astride the fastener 410 (the figure 2 is an exploded view for understanding and the jumper is shown above the fastener).
  • the rider has a core 431 on which is fixed the lateral abutment 420, and two wings 432 each comprising a round hole 433 and an elongate slot 434 secant with respect to the oblong slots 413 of the fastener.
  • the jumper 430 is adjustably secured to the fastener 410 by a first through bolt 435 placed through the round holes 434 of the jumper and oblong slots 413 of the longitudinal section 411, and a second through bolt 436 placed through the holes.
  • a first through bolt 435 placed through the round holes 434 of the jumper and oblong slots 413 of the longitudinal section 411
  • a second through bolt 436 placed through the holes.
  • the adjustment of the angle ⁇ of the jumper is useful because most screwdrivers have an angle between the surface of their base and the axis of rotation of their screwing / unscrewing shaft. Thanks to this arrangement, the screwdriver support according to the invention has a degree of freedom and angle adjustment.
  • This function is also advantageous when the rider includes a support surface 431 sufficient to receive the screwdriver, in particular the base of its handle (usually the base of the battery).
  • this support surface is constituted by a plate 450 of surface greater than the core 431 of the rider to allow the support, in use, of most of the surface of the base of the screwdriver (see Figures 4 and 5 ).
  • This plate is fixed on the jumper perpendicularly to the lateral stop 420 and the transverse stop 440 so as to form a particularly effective trihedron to lock the screwdriver in the use position.
  • the lateral stop 420 is adjustably fixed to the adjustment member 430.
  • it is adjustable to apply the lateral stop against the screwdriver in position use.
  • the trihedron formed by the lateral abutment 420, the plate 450 and the transverse stop 440 is adjustably mounted on the rider to allow lateral translation of the trihedron and allow to apply the lateral abutment 420 against the screwdriver.
  • the lateral stop is fixed in a non-adjustable manner on the adjustment member, for example by welding.
  • the arrangement of the lateral stop 420 with respect to the screwdriver support must be designed to allow the use of different screwdrivers.
  • it must be taken into account the lateral dimensions of the screwdrivers, especially at the base of the handle, at the battery. These dimensions define the inter-axis E which is the distance separating the lateral stop 420 and a parallel plane P passing through the axis of rotation XX of the control shaft 22 of the lifting mechanism (see FIG. figure 5 ).
  • the inter-axis E depends on the lateral wheelbase of the screwdriver used.
  • the inter-axis E is substantially equal to half of the lateral wheelbase of the screwdriver at the bottom of the handle (usually it is the location of the battery).
  • the lateral stop 220 When the lateral stop 220 is adjustably mounted on the screwdriver support (embodiment not shown), it is sufficient to adjust the inter-axis position of the lateral stop when the screwdriver is in engagement with the control shaft. of the gear, so that the lateral stop is in contact with the handle of the screwdriver.
  • the lateral stop 420 When the lateral stop 420 is fixedly mounted on the screwdriver support, it should be ascertained during manufacture of the support according to the invention that most of the screwdrivers can be locked laterally in rotation during use. , even if in the locked position, the screwdriver is not completely vertical.
  • the height h2 of the stop (see figure 3 ) should be at least 3 cm, preferably between 5 and 10 cm.
