  • the actuating element as seen in the fastening direction, formed oval.
  • the actuating element is elliptical.
  • the object is achieved in a transport device for transporting fasteners in a transport direction into a receptacle, with a free space for a drive-in element of the drive-in device, wherein the free space extends in a fastening direction and comprises the receptacle, in that the transport device comprises a release element which can be brought into engagement with an actuating element of the driving through the free space driving element to trigger a transport of a fastener into the receptacle by the transport device.
  • the transport device comprises a release element which can be brought into engagement with an actuating element of the driving through the free space driving element to trigger a transport of a fastener into the receptacle by the transport device.
  • the transport device comprises an energy store, which pre-loads the trigger element against actuation by the actuating element.
  • the energy store comprises a spring element, which is particularly preferably designed as a helical spring.
  • the transport device has a transport element which can be brought into engagement with the fastening element or a strip comprising the fastening element in order to transport the fastening element in the transport direction into the receptacle.
  • the transport element is deflected upon actuation of the transport device by the actuating element.
  • a force of the energy storage counteracts this deflection.
  • the transport element after the end of the actuation by the actuating element, the transport element performs an advancing movement counter to the deflection in order to transport the fastening element into the receptacle.
  • the feed movement is accomplished or supported by the power of the energy storage.
  • the transport element has a driver for transporting the fastening element.
  • the driver is spring-loaded by a driver spring against the fastener or a strip comprising the fastener.
  • the transport element is designed as a transport slide.
  • the transport slider is linearly movable.
  • the transport element has one or more transport teeth for engagement in corresponding recesses on a strip comprising the fastening element.
  • the driving element or the transport device is integrated in a device for driving fasteners into a substrate.
  • the device preferably comprises a rotary drive for the driving element.
  • the actuating element is adapted to actuate the transport device during a driving operation.
  • the actuating element is suitable to actuate the transport device at the end of the driving operation.
  • the actuating element is in an initial position of the Drive element arranged offset against the mounting direction relative to the trigger element. During the driving operation, the driving member is moved in the driving direction, so that the operating member engages with the conveying means at a desired timing to operate them.
  • Fig. 1 shows an electric screwdriver 10 as an exemplary driving device in a side view.
  • the electric screwdriver 10 has an angled housing 11, in which a motor 12 is coupled by a drive train 13 with a rotary drive 14.
  • the drive train 13 includes, for example, at least one spindle, a transmission, an overload clutch and / or a Tangentialschlagtechnik.
  • a power supply of the electric screwdriver 10, in particular of the motor 12, is effected by an accumulator 15, which is detachably fastened to a foot 16 of the housing 11.
  • the rotary drive 14 defines a driving direction 17 of the electric screwdriver 10 by aligning a driving element 18 along the driving direction 17.
  • a user of the electric screwdriver 10 exerts a contact pressure in the drive-in direction 17 in order to drive a fastener into a workpiece in a rotating manner.
  • the user can create a remote from the rotary drive 14 back 21 of the housing 11.
  • Thumb and forefinger are on the side of the housing 11 on both sides of the plane of symmetry 20 in a support area 22 at.
  • the support area 22 begins at the rear 21 of the housing 11 and has two legs 23 which extend in the direction of the rotary drive 14 and U-shaped enclosure 11 between them.
  • the angled housing 11 has a shaft 25.
  • the shaft 25 forms together with the support portion 22 a handle 28.
  • the leading hand can grip the shaft with the remaining fingers.
  • An operating button 30, which is for activating the electric screwdriver 10, in particular the motor 12, is provided on a front side 29 of the shaft 25 facing the rotary drive 14.
  • a recessed grip 34 and a contact surface 31 are provided for a second hand.
  • the contact surface 31 is arranged on the side opposite the shaft 25 of the guide plane 24 and approximately in extension of the shaft 25th
  • the drive-in element 18 includes a rotary drive 45, which can be brought into engagement with the rotary drive 14 of the drive-in device 1 for torque transmission, and a screw drive 46.
  • the drive element 18 comprises a drive mechanism 18 for transporting fastening elements 41 in a transport direction 42 in front of the driving element 18 for rotationally driving the fastening elements 41.
  • the driving-in element 18 has an actuating element 43, which serves to actuate the transport device 40, in order in each case to transport one of the fastening elements 41 into a receptacle 44 of the transport device 40.
  • the actuating element 43 is designed as a circumferential elliptical projection on a circumference of the driving element 18 and thus has two ramps 47 relative to the circumference of the driving element 18.
  • the actuating element 43 protrudes perpendicular to the fastening direction 17 from the driving-in element 18.
  • the transport device has a preferably channel-shaped clearance 48 for the drive-in element 18 of the drive-in device 1, the clearance 48 extending in the attachment direction 17 and comprising the receptacle 44.
  • the transport device 40 comprises a triggering element 49, which is brought into engagement with the actuating element 43 of the driving element 18 when the driving element 18 is moved in the driving direction 17 through the clearance 48 in order to transport a fastening element 41 into the receptacle 44 by the transporting device 40 trigger.
  • An educated as linear along the transport direction 42 movable transport slide Transport element 53 is fastened by means of a screw 54 to the trigger element 49 and comprises a driver 51 which can be brought into engagement with recesses 56 of the strip 55, and a driver spring 52 which pre-loads the driver on the strip 55 with the fastening elements 41.
  • the trigger element 49 in Fig. 2 to 4 When actuated by the actuator 43, the trigger element 49 in Fig. 2 to 4 deflected to the left against the force of a spring element 50, which pre-loads the trigger element 49 against the actuation by the actuating element 43 and thus acts against the deflection.
  • the force required for this is applied via the driving element 18 through the driving-in device 1, so that a user of the driving-in device 1 is relieved of load.
  • the driver is thereby moved to the next recess 56 of the strip 55 and engages there by means of the driver spring 52 a.
  • the triggering element 49 executes an opposing movement for deflection feed movement to transport the fastener into the receptacle by the spring element 50, the trigger element 49, the transport element 53 and the strip 55 with the fasteners 41 in the Fig. 2 to 4 moved to the right.
  • the transport element has one or more transport teeth for engagement in the recesses 56.
  • the actuating element 43 is arranged offset against the fastening direction 17 relative to the triggering element 49.
  • the driving element 18 in the driving direction 17 and thus the actuator 43 is moved to the trigger element 49, so that the actuator 43 engages towards the end of the driving operation by rotation via one of the ramps 47 with the trigger member 49 of the conveyor 40 to the Transport device 40 to operate.
