Definitions

  • Hand-held device for tensioning straps The invention is based on a hand-held device for tensioning straps, which can be closed by means of a buckle or seal, with a band clamp arranged above a base plate for clamping the hand-held device onto the band to be tensioned, one in front of the Band clamp arranged, drivable
  • Tensioning roller a shearing device arranged in front of the tensioning roller for cutting off the tensioned strapping tape from the tape supply and a handle for grasping the device.
  • a shearing device arranged in front of the tensioning roller for cutting off the tensioned strapping tape from the tape supply and a handle for grasping the device.
  • Such a device is pushed with its base plate under the strapping band which is placed around a package as a loop and clamped in place by means of the band clamp pressing against the base plate. Then the piece of tape leading from the buckle to the tape supply is guided through the shearing device to the tensioning roller and fixed there.
  • the tensioning roller is now tensioned by means of a tensioning lever designed , for example, as a ratchet lever.
  • the shear device is actuated by means of a hand lever in order to cut off the tensioned loop from the band supply and the band clamp is opened by means of a second hand lever so that the hand-held device can be removed.
  • the known devices have the disadvantage that they have to be handled with two hands and the tensioning of the U-lacing band is very uncomfortable if the device does not have to be used at table height but in a lower or higher position.
  • the object of the invention is to provide a hand-held device for tensioning strapping tapes, the handling of which is considerably easier and also in sec.
  • the motor can be an air motor or an electric motor operated by Netzstrom. So that the device can be used anywhere, the motor is advantageously a battery-operated electric motor which is enclosed by a plastic housing which has a hollow handle in which at least one battery is accommodated.
  • Fig. 1 is a side view
  • FIG. 3 shows a side view corresponding to FIG. 1 of a modified embodiment of the invention
  • Fig. 4 is a side view
  • FIG. 5 shows a plan view of a hand-held device with a sealing device.
  • a hand-held device for tensioning a strap 1 is shown in side view.
  • the strapping band 1 is guided around a package and the loop thus formed is closed by a self-closing buckle 2.
  • the hand-held device has a vertical base plate 3 and a stand plate 4 which is at right angles thereto. With this stand plate 4, the hand-held device is pushed under the strap 1 leading to the buckle 2 and by means of one against the stand plate -1-
  • the band clamp 5 is opened and closed by means of a hand lever 8.
  • the strapping band 1 leading from the buckle 2 to the band supply is wound into the slot 19 of a shearing device 7 and then with one turn around the tensioning roller 6.
  • the strap 1 can now be tensioned by hand.
  • the tensioning roller 6 is connected to its drive by means of a one-way clutch or overrunning clutch, so that tensioning by hand is initially possible.
  • the tensioning roller 6 is driven by a motor 11 which is fed by a battery 12 which is accommodated in a hollow handle 10.
  • the motor 11 is switched on and off via a switching element 13 which is arranged at the upper end of the handle 10 and is designed in the manner of a trigger of a pistol.
  • the inner rotatable part of the shearing device 7 is pivoted by pivoting the hand lever 9 so that its shearing edge, in cooperation with the counter cutting edge of the fixed part, shears off the tensioned band loop from the band supply.
  • the electric motor 11 is accommodated in a plastic housing 17 which is connected in one piece to the hollow handle 10.
  • the longitudinal axis of the handle 10 is at an angle of 90 to 120 ° to the axis of the motor 11.
  • the switching element designed in the manner of a pistol trigger is arranged in the interior angle between the motor housing 17 and the handle 10.
  • the base plate 4 is connected to the free end of the handle 10 via a support bar 16 aligned with the underside of the base plate 4.
  • the plastic housing 17 is also connected via a connecting bracket 15 to a gear box 14 and the base plate 3.
  • the band clamp 5 and the shear device 7 are actuated by means of the two hand levers 8 and 9, this can also be done by motor in the device according to FIG. 3.
  • the motor 11 * can be driven in two directions of rotation.
  • the switching element 13 accordingly has three switching positions, namely: off, clockwise rotation, counterclockwise rotation. If the roller 6 is driven by clockwise rotation, then when the motor runs counterclockwise 11 via coupling parts 20 to
  • a ratchet wheel 22 is connected to the tensioning roller 6, which interacts with a clinch 21 which is articulated on a coupling 20 which is coupled to the shearing device 7 and the band clamp 5. If the trigger-like switching member 13 is "pulled through” in this hand-held device after the strapping band 1 has been tensioned, then the ratchet wheel 22 presses against the pawl 21, so that the coupling 20 is moved to the right, with the result that the Shear device 7 cuts the strapping band 1 and then the lever 8, which can also be moved by hand, is pivoted to the right, as a result of which the band clamp 5 opens.
  • the lever 8 is articulated on the coupling 2 via an elongated hole 25 which acts as a drag clutch. 4 and 5 is in front of the
  • Shear device 7 arranged a seal pressing device 30.
  • This has a rigid lower plate 31 at the level of the band 1 to be tensioned and a movable pressure plate 32 located above it.
  • the movable pressure plate 32 can be pressed by means of an eccentric cam 33 against the seal 34 placed on the lower plate 31.
  • the eccentric cam 33 is coupled to the shearing device 7 in such a way that, after the maximum pressing pressure has been applied to the seal 34, the closed band loop is cut off from the band supply.
  • the eccentric cam 33 is connected to a hand lever 35. This is arranged so that at the end of its swiveling movement in order to apply the closing pressure of the seal 34, it presses on a lever 9 'of the shearing device 7 in order to actuate it.
  • the tape clamp is on the base plate 4.
  • a pad 40 made of plastic and on the underside of the clamping plate 5 are pointed, about 0.3 to 0.6 mm high teeth.
  • the plastic pads 40 have a hardness of 100 to 150 shore and are made of polyamide or nylon.
  • the elasticity of the plastic plate 40 in conjunction with the effect of the teeth penetrating the textile band means that the band is reliably grasped and cannot slide out of the band clamp 5.
