Definitions

  • the invention relates to a device for attaching fasteners with a profile part arranged below the fastener head, which has a part projecting in the direction of the fastener head.
  • a device of this type known from DE-33 31 885 C2 is used for attaching and detaching screw hooks and has a hook receiving part with a receiving member for the hook shaft.
  • the hook receiving part is designed as an approximately U-shaped arm which is connected to a handpiece 4.
  • Edge cutouts for engaging hook-shaped parts of the screw hook are incorporated on the outside of the legs of the receiving fork. These hook-shaped parts of the screw hook are bends of an arm which is firmly connected to the screw of the hook. When turning the handpiece to screw in the screw hook, it is grasped at the bends and rotated together with the bends.
  • bends are therefore only carriers which, after screwing in, will be aligned in the same way as the hook, which is used to hang up objects, so they are more likely to have a random alignment, which results when the arm on which the bends are formed is on the Underground comes into contact.
  • the object of the invention is to design a device of the type mentioned at the outset in such a way that an aligned fastening of the profile parts with respect to the parts projecting therefrom can be ensured.
  • This object is achieved according to the invention in that at a distance apart from a receiving part which carries out a rotary and / or impact movement during attachment, which receives the fastener head and which can be connected to a drive unit, an intake which is oriented parallel to the axis of rotation or impact and is open in the direction of insertion or insertion for receiving the part projecting from the profile part is provided as a stop.
  • the profile part to be fastened is always aligned in the same position as it is when it is inserted into the device, since it cannot twist itself when the fastener is screwed in or driven in relative to the device. The operator therefore only has to pay attention to the device itself, so that successive profile parts always have the same orientation.
  • the profile part to be fastened is therefore held securely on the device against twisting, so that no additional tools are required and therefore it cannot be held by hand.
  • the device according to the invention can be adapted in a simple manner to parts projecting from the profile parts to be fastened in the form of webs, brackets, pins or the like, since the receptacle can be designed as a groove, bore, depression or the like on a front part of the drive unit carrying the receiving part . It is therefore also possible to quickly adapt to changing profile parts or changed webs, brackets, pins or the like in a simple manner.
  • the receptacle is formed by a side limitation of the front part and a spring-loaded retaining tab fastened thereon.
  • This positive effect also contributes if the width of the receptacle is slightly smaller than the thickness of the part of the profile part to be accommodated in it and the free edge region of the spring-acting retaining tab is bent away from the receptacle at an acute angle to form an insertion extension. This also makes it easy and simple to insert the projecting part of the profile part into the receptacle.
  • the attachment device i.e. for screwing in and / or driving in fasteners 1 with a profile part 3 arranged below the fastener head 2 consists essentially of a receiving part 4, which is designed with means for holding a part arranged on the profile part 3 in the form of a web 5 and to a drive unit 6 can be connected.
  • the fastener head 2 is inserted into the drive-in or screw-in nut 9 provided at the foremost end of the receiving part 4 and at the same time the web 5 protruding from the profile part 3 in the direction of the fastener head 2 is inserted into the groove 8.
  • the screwing-in or driving-in process for the fastener 1 can therefore now be carried out without the profile part 3 being able to twist. Therefore, a constant alignment of the webs 5 of successively assembled profile parts 3 is ensured without additional mounting measures, such as holding by hand or holding with pliers, being necessary.
  • the groove 8 for receiving the web 5 is formed on a front part 10 carrying the receiving part 4, which can be exchanged as required or depending on the design of the webs or the like.
  • This front part 10 can for example consist of a flat steel construction or can also be designed as a cast part.
  • the attachment part 10 is fastened, for example, to the drive unit 6 in a simple manner by means of a locking screw 11.
  • This attachment part 10 is advantageously formed from two separate sections 12 and 13, which can be telescopically pushed into one another, in order thereby to create a possibility of compensation during the backward movement of the impact or screw-in nut.
  • the groove 8 is formed by a side boundary 14 of the front part 10 and a spring-loaded retaining tab 15 fastened to it.
  • the width of the groove 8 is made slightly smaller than the thickness of the web 5 to be inserted in the profile part 3, the free edge region 16 of the spring-acting retaining tab 15 being bent away from the groove 8 at an acute angle to form an insertion extension. This makes it easy to insert the web 5 into the groove 8.
  • the projecting web 5 of the profile part 3 can be provided with different types of recesses 17 in order then to be able to fasten or hang up corresponding parts on this web 5.
  • a fastener 1 which can be driven into a predrilled opening is shown here as the fastener, instead of which other fasteners, that is to say screws, shooting bolts, self-drilling screws or the like, can be used on the device in the same way.
  • a roughening or toothing 18 is provided on the shaft of the fastener 1, so that the profile part 3 can be pre-assembled on the fastener 1 with a positive fit. An captive mounting of the profile part 3 on the fastener 1 is thus ensured until the final fastening and thus the fastening head 2 come to rest on the surface of the profile part 3.
