Definitions

  • the invention relates to a device of the type specified in the preamble of claim 1.
  • screws of the same length can always be used to bridge different thicknesses of insulating material when fastening covering sheets or plates, but then the length of the tubular extension changes on the plastic holder accordingly.
  • the screw heads are arranged more or less deeply recessed in the tubular extensions, so that a drive shaft with a mandrel engaging in the tubular extension must be lowered to different degrees over the lower end of a movable base frame in order to drive it in completely to be able to effect the screw.
  • a setting device known from EP 0 535 547 B1 no fastening elements can be screwed in that have a large-area washer with a tubular extension made of plastic.
  • the fastening elements for which the known setting device is provided have a washer or a load distribution plate made of metal.
  • This setting device also has no holding arrangement for the fastening element, which consists of a mandrel which engages in a tubular extension of a plastic holder and is arranged at the free end of the drive shaft. Rather, a fitting projection is provided in this setting device, which at a contact point on the load distribution plate next to one Ramp attacks to fix the load distribution plate.
  • the holding arrangement also serves here as an anti-rotation device.
  • the present invention has for its object to provide a structurally simple and easy-to-use adjustment device for adapting tubular extensions of different lengths to the plastic holders and an optimal holding arrangement and anti-rotation for the plastic holder.
  • the measures according to the invention can be achieved in a very simple manner that the mandrel to be inserted into the tubular extension, which is also connected to the screwdriver via a corresponding drive shaft, can engage correspondingly deeply in the tubular extension. It is thus achieved solely by the mutual adjustment of the coaxially guided pipe parts into one another in relation to tubular extensions of different lengths on the plastic holders.
  • a spring-loaded adjustable bolt is arranged on the outer tube part, which engages in a radial bore formed by the inner tube part. This means that not only is simple adjustment possible, but also secure locking and, above all, self-locking locking, which remains securely in this locking position until it is released manually.
  • the radial bores on the inner tube part follow one another with an axial grid spacing. This enables a gradual adjustment with an order of magnitude matched to the grid dimensions of the tubular extensions of plastic holders.
  • a depth stop that is effective when used in cooperation with a base frame is assigned to the external pipe part. This measure ensures that the feed movement for the Plastic holder itself is always coordinated in such a way that the large-area washer of the plastic holder comes to rest in a corresponding manner on the surface of a web to be fastened. The possibility has therefore been created that, despite a simple adjustment option for adapting to tubular extensions of different lengths, an adjustment of a depth stop is not also necessary at the same time. The depth stop is therefore always dependent on the final setting of the plastic holder, whereas the simple mutual adjustment of the two coaxially aligned pipe parts can bridge the amount by which the screw head is sunk more or less deeply into a more or less long tubular extension ,
  • the depth stop is designed as a collar encompassing the outer tube part, which receives the spring-loaded adjustable bolt on one side and has a stop lug on the opposite side.
  • a solution that is both functionally and structurally very simple can be created, so that the adjustment can be carried out optimally and a correspondingly stable stop lug can also be created.
  • An optimal protection against rotation is achieved in that the bolt forming the protection against rotation for the plastic holder is provided in a freely projecting manner on a stop surface at the free end of the screwing device and is effective as a stop preventing rotation at the edge area of the large-area washer of the plastic holder.
  • the guide shafts or guide rails previously required in such arrangements can be omitted along the entire displacement path of the screwing device. It is also in no way necessary to hold the large-area washer of the plastic holder until it is finally seated by means of jaws that can be swung away or spring-loaded that can be pushed back, since this also resulted in a complex and space-intensive construction.
  • the arrangement of one or more cantilevered bolts alone provides a sufficient possibility of providing stops to prevent the plastic holder from rotating.
  • This design is effective in the same way whether the device is used as a handheld device or is used in a movable base frame. Even when used as a handheld device, the plastic holder is aligned with and around the mandrel and secured against twisting by the bolts acting as stops. This results in the same advantageous results when used in a hand-held device as when used in a movable base frame.
  • the device according to the invention creates a device which is significantly improved in terms of design, which is easier to handle and which, above all, allows good access to all important areas. Even if there should ever be any malfunctions in the supply of the fastening elements and in particular the plastic holder, manual intervention is possible without any problems, since no disruptive guides, shafts or cladding are required.
  • the bolt or bolts is (are) arranged at an edge of the stop surface, the bolt (s) being attached to a plastic holder is only effective at a longitudinal limit of the plastic holder to prevent rotation. It is therefore only necessary to provide an anti-rotation device so that there is no need to provide appropriate stops or stop areas on opposite longitudinal boundaries of the plastic holders or even circumferentially closed.
  • Such a bolt would in itself be sufficient, but the arrangement of at least two bolts ensures that the plastic holder cannot rotate in either direction about the screw-in axis.
  • the length of the freely projecting bolts is approximately equal to the thickness of the large-area washer on the plastic holders in the corresponding stop area. Since the plastic holder is supported on the stop surface formed at the free end of the screwing device, a short length of the bolts is sufficient to provide an effective anti-rotation device for the plastic holder. It is therefore only necessary for these bolts to have a small length in order to provide support at the corresponding point, that is to say in the corresponding stop area on the longitudinal delimitation of the washer.
  • the device according to the invention is therefore advantageously advantageous both when used as a hand-held device and when used in a movable base frame.
  • the mandrel has a body with a threaded bolt for attachment to the free end of a drive shaft and on the body and the threaded bolt a tubular member for attachment to the body at the free end of the drive shaft is attached, which has retaining means in the form of at least one projecting nose which, in cooperation with at least one annularly projecting bead formed in the interior of the tubular extension of a plastic holder, is axially secured provides bracket.
  • the plastic holder By simply inserting the dome when pressing down the screwing device or when attaching a plastic holder to the screwing device, the plastic holder can be axially secured against the screwing device, this being able to be carried out without any special effort. Even if the bulge formed in the plastic holder and projecting inwards in a ring, which can also be in a multiple arrangement, runs circumferentially closed, an easy insertion is necessary, since only partial areas on the circumference of the dome have to jump over these bulges or bulges.
  • EP 0 783 063 AI shows a cylindrical part of a screwdriver.
  • a screwdriver tip is inserted into the cylindrical part.
  • annular ribs are provided which come into clamping engagement with the cylindrical part of the screwdriver.
  • the cylindrical part of the screwdriver is also used for axial mounting, but it is assumed that the cylindrical part of the screwdriver and the plastic holder rotate together. Otherwise undesirable frictional heat would arise between the two.
  • This known device is unsuitable for screwing in fasteners in which the plastic holder should not rotate when screwing in, because the washer is to maintain a certain orientation around the screw-in axis until the fastener is finally set.
  • Frictional heat cannot arise when the device according to the invention is used, because here there is no friction-locked holder between the plastic holder and the dome, but rather a form-fitting holder that allows mutual relative rotation without further ado.
  • dome can be attached to any screwing device in order to enable it to be able to place fastening elements of the type in question here.
  • two projecting lugs are formed diametrically opposite one another on the dome.
  • the insertion and proper mounting are further improved in that the projecting lugs have an entry ramp running at an acute angle to the screw-in axis and a stop falling steeply behind.
  • the insertion process is thus made considerably easier even when the plastic holder is inserted by hand, and nevertheless a sufficient safeguard against axial displacement of the plastic holder is ensured.
