Definitions

  • the present invention relates to a fastener-feeding device for a power driven tacker referred to in the preamble of claim 1.
  • Such a device is from the US 2001 005 0465 A known.
  • Such fastener feeders for powered tackers such.
  • B. screwdrivers for example, are designed as pure fastener magazines or as extension devices.
  • a ringenzukgworm adopted for a driving or bobrace which can be arranged with a main body via a clamping ring on a flange of a screwdriver.
  • a run of the screw feed device is arranged with a tubular part displaceable on the first unit.
  • a lever element is arranged with an eccentric over which a two ends of the clamping ring passing through screw to reduce the diameter of the clamping ring can be stretched.
  • the screwdriver has a holding projection, on whose outer circumference a circumferential recess is arranged.
  • a fastening sleeve of the fastener feeding device can be held, which is fixedly arranged in a housing of the fastener feeding device.
  • the fastening sleeve has two opposing openings in which clamping blocks are guided radially displaceable. Outside of the mounting sleeve around a locking sleeve is pivotable mounted, which has internal circumferential grooves for the clamping blocks.
  • the clamping blocks By pivoting the locking collar, the clamping blocks can be reversibly converted into a blocking position in which the clamping blocks are connected via clamping surfaces both with the recesses on the holding projection and with the circumferential grooves.
  • a detent sleeve with spring fingers is used only for holding the locking sleeve on the mounting sleeve.
  • a disadvantage of this solution is the large number of components required for the connection device.
  • the object of the present invention is to provide a fastener supply device which avoids the mentioned disadvantages and which is easy to handle.
  • the at least one blocking element is acted upon elastically by a spring element in the direction of its locking position and has an externally accessible actuating section for the manual transfer of the blocking element from its locking position into its release position.
  • the blocking element can be automatically transferred via the spring element in its locking position and only needs to be manually transferred to the release position.
  • the arrangement of the actuating portion directly to the blocking element can also reduce the number of components of the locking device and thus the assembly effort.
  • two locking elements are present, which lead each other and are mutually displaceable.
  • an unintentional release is prevented because both locking elements must be actuated to release the fastener feeding device of the tacker.
  • the locking elements are U-shaped, wherein in each case a first U-leg as a guide bush and a second U-leg is designed as a guide pin and the guide pin of a respective locking element in the guide bushing of the other locking element slidably is guided.
  • the locking elements lead each other and at the same time embrace the receiving space, creating a simple easy-to-install locking device is created.
  • the locking portions of the locking elements are each arranged on the guide pins receiving ends of the guide bushes, wherein the locking portions protrude arcuately from the guide bushes and embracing the receiving space for the counter-coupling portion partially.
  • a good kinematics is achieved because the locking portions are under tensile load of the spring elements.
  • FIGS. 1 to 4 show a designated generally with 10 fastener supply means according to the invention which is releasably fixed with a coupling portion 14 on a counter-coupling portion 41 formed as a retaining projection of a shown in the figures only with its tool-side end, power driven Eintreib mars 40.
  • the partially reproduced power driven tacker 40 is designed as an electrically operated screwdriver.
  • the coupling portion 14 has for this purpose a receiving space 17 into which the counter-coupling portion 41 of the tacker 40 can be inserted.
  • the fastener supply device 10 is not a screw magazine with integrated transport mechanism 16 for the transport of a in the figures formed screw magazine strip formed.
  • the fastener-feeding device 10 designed as a screwing Eintreibtechnik Weg 13 is guided, which can be rotatably actuated via the power driven tacker 40 and this is coupled with a tool holder 42 of the tacker 40.
  • the driving tool 13 defines a tool axis A.
  • the fastener supply device 10 has a guide unit 11 which includes the coupling portion 14 and which is formed here as a guide housing, and a carriage unit 12 which is held displaceably on the guide unit 11 in the direction of the tool axis A.
  • the guide unit 11 carries the transport mechanism 16 and guides the screw magazine strip. Furthermore, the guide unit 11 has a stop 15 with which the fastener-feeding device 10 can be attached to a substrate for carrying out a driving operation.
  • a generally designated 20 locking mechanism is arranged on the coupling portion 14, which is formed as a coupling sleeve which can receive the counter-coupling portion 41.
  • This locking mechanism 20 has a first locking element 21 and a second locking element 22, which together enclose the tool axis A.
  • Each of the locking elements 21, 22 is approximately U-shaped, wherein in each case a U-leg of the locking elements 21, 22 has a cylindrical guide bushing 26 and a protruding at the end of the guide bush 26 arcuate locking portion 23.
  • the locking portions 23 are bent away from the guide bush 26 in the circumferential direction about the tool axis A in each case a bit far.
  • a spring element 25 is arranged in each case and a guide pin 27 of the respective other blocking element 21, 22 guided axially movable.
  • the guide pins 27 are acted upon in the direction of the guide bush 26 out elastically.
  • both locking elements 21, 22 are pressed apart, wherein the movement path is limited by the guide unit 11, the area serves as a stop for the locking elements 21, 22.
  • actuating portions 24 are formed, the wall of the guide unit 11 and the housing enforce and manually operated from the outside.
  • the actuating portions 24 and the respective locking elements 21, 22 are rigidly connected or integrally formed.
  • the actuating portions 24 of the locking elements 21, 22 are pressed manually in the direction of the tool axis A in the guide unit 11 and in the guide housing.
  • the guide pins 27 move into the guide bushes 26 against the force of the spring elements 25, wherein the locking portions 23 are each moved out of the recess 43 on the mating coupling portion 41 until the mating coupling portion 41 of the tacker 40 are moved out of the coupling portion 14 of the fastener supply device 10 can.
  • the locking portions 23 are then outside the receiving space 17th
