Definitions

  • the application relates to a device for driving a fastener into a substrate.
  • Such devices usually have a piston for transmitting energy to the fastener.
  • the energy required for this must be provided in a very short time, which is why, for example, so-called Federnaglind initially a spring is tensioned, which releases the clamping energy abruptly to the piston during the driving operation and accelerates it to the fastener.
  • the recoil When a center of gravity of the device is not on the trajectory of the piston or its extension, the recoil includes a torque which causes the entire device to tilt as the fastener is driven into the ground
  • the object of the invention is to improve the fastening quality of the aforementioned device.
  • the object is achieved in a device for driving a fastener into a substrate, having a center of gravity, a movable between a starting position and a setting energy transfer element for transmitting driving energy to the fastener, the driving energy providing piston drive, a housing and a fastener during the Driving leading bolt guide, wherein the bolt guide is rotatably mounted on the housing with respect to a rotation about the center of gravity. Due to the rotationally movable bearing, the bolt guide remains in its position due to its inertia even if the rest of the device already tilted due to the recoil. This applies to the period in which the fastener is driven into the ground.
  • An advantageous embodiment is characterized in that the device has a damping element which dampens a rotational movement of the pin guide around the center of gravity.
  • the bolt guide has a holder which is rotatably mounted on the housing with respect to a rotation about the center of gravity.
  • the holder comprises a delay element for braking the energy transmission element.
  • An advantageous embodiment is characterized in that the bolt guide is rotatably mounted on the housing along an angular range of at least 2 °.
  • the angular range extends over at least 3 °, more preferably over at least 5 °.
  • Fig. 1 shows a driving-in device 10 for driving a fastener, such as a nail or bolt, into a ground in a side view.
  • the driving-in device 10 has an energy transmission element (not shown) for transmitting energy to the fastening element and a housing 20, in which the energy transmission element and a likewise not shown drive device for conveying the energy transmission element are accommodated.
  • the driving-in device 10 furthermore has a handle 30, a magazine 40 and a bridge 50 connecting the handle 30 to the magazine 40.
  • the magazine is not removable. Attached to the bridge 50 are a scaffold hook 60 for suspending the driving-in device 10 on a scaffold or the like, and an electrical energy store designed as a battery 590.
  • a trigger 34 and designed as a hand switch 35 Grifflagler are arranged.
  • the driving-in device 10 has a guide channel 700 for guiding the fastening element and a pressing device 750 for detecting a distance of the driving-in device 10 from a substrate, not shown. Aligning the driving device perpendicular to a substrate is supported by an alignment aid 45.
  • Fig. 2 shows the driving device 10 with the housing 20 open.
  • a drive device 70 for carrying a hidden in the drawing energy transfer element is added.
  • the drive device 70 comprises an electric motor, not shown, for converting electrical energy from the battery 590 into rotational energy, a transmission 400 comprising a torque transfer device for transmitting a torque of the electric motor to a trained as a spindle drive motion converter 300, a roller train 260 comprehensive power transmission device for transmitting a force from the motion converter to a mechanical energy accumulator designed as a spring 200 and for transmitting a force from the spring to the energy transmission element.
  • Fig. 3 shows the driving device 10 in an oblique view with the housing 20 open.
  • the front roller holder 281 can be seen.
  • the delay element 600 is held in position by the retaining ring 26.
  • the nose 690 has, among other things, the Anpress catalyst 760 and the unlocking 720.
  • the pressing device 750 has the guide channel 700, which preferably comprises the Anpressterminler 760, and the Connecting rod 770 on.
  • the magazine 40 has the feed element 740 and the feed spring 735.
  • the driving-in device 10 has an unlocking switch 730 for unlocking the guide channel 700, so that the guide channel 700 can be removed, for example in order to be able to remove jammed fastening elements more easily.
  • Fig. 4 shows a nose 690 of a device for driving a fastener into a substrate in an oblique view.
  • the nose 690 comprises a guide channel 700 for guiding the fastener with a rear end 701 and a relative to the guide channel 700 in the direction of the set axis slidably disposed holder 650 for holding a delay element, not shown.
  • the holder 650 has a bolt receptacle 680 with a feed recess 704, through which a nail strip 705 with a plurality of fastening elements 706 can be fed to a firing section 702 of the guide channel 700.
  • the guide channel 700 also serves as Anpressdoner a pressing device, which has a connecting rod 770, which is also displaced upon a displacement of the guide channel 700 and thus indicates a pressing of the device to a substrate.
  • Fig. 5 1 shows a drive-in device 100 with a center of gravity 110, a power transmission element 120 movable between a starting position and a setting position for transmitting driving energy to a fastening element not shown, a piston drive 130 providing the driving force, a housing 140 and a bolt guide 150 guiding the fastening element during driving.
  • the bolt guide 150 has a holder 160 and is mounted on the housing 140 only via the holder 160.
  • the holder 160 is rotatably connected to the rest of the bolt guide 150. With respect to a rotation about the center of gravity 110, the holder 160 and thus the bolt guide 150 are rotatably mounted on the housing 140.
  • the bolt guide Due to its rotational inertia during the period in which the fastening element is driven into the ground, due to its rotational inertia, the bolt guide remains on the ground and ensures guidance of the fastening element until the fastening element is driven into the ground.
  • a rotational movement 170 of the driving-in device 100, in particular the housing 140, caused by a recoil is compensated and the fastening quality is improved.
  • the drive-in device 100 has a damping element 180, which is arranged on the side facing away from the center of gravity 110 of the holder 160 in front of the holder 160 and behind a support member 145 of the housing 140 and therefore during a recoil rotational movement of the bolt guide 150 relative to the housing 140 around the Center of gravity 110 dampens.
  • the driving-in device 100 has a further damping element 185 which is arranged on the side of the holder 160 facing the center of gravity 110 and therefore has no appreciable contribution to the damping of a rotational movement of the bolt guide 150 during a recoil.
  • An angular range along which the bolt guide is rotatably mounted on the housing depends on a distance between the holder 160 and the support member 145 and is presently 5 °.
  • the holder 160 includes a delay element 190 for decelerating the power transmission element 120.
