Definitions

  • the invention relates to a setting device having the features of the preamble of claim 1 and the combination of a setting device with a fastening element having the features of the preamble of claim 7.
  • the object of the invention is therefore to improve the setting behavior of such a system of setting tool and fastener.
  • the invention proposes a setting tool for driving a fastener, wherein the fastener has a retaining plate with which a plate-shaped insulating material, in particular a plate made of hard foam, mineral fiber, wood wool or the like., On a Underground can be attached.
  • the holding plate is in particular substantially circular with an outer diameter of 40 to 120 mm, in particular from 50 to 100 mm.
  • the fastening element according to the invention also has an anchoring element for anchoring in a substrate.
  • the anchoring element may for example be a screw, in particular if the substrate is made of wood, or a nail or a screw nail.
  • the anchoring element is preferably a dowel with a screw, a nail or a screw nail.
  • the setting device and the fastening element are in particular designed such that the setting device allows setting of the fastening element such that the retaining plate in the set state has a defined depth relative to an outer surface of the plate-shaped insulating material.
  • This setting is referred to below as sunk set the holding plate.
  • the countersunk setting requires that the setting device and / or the fastening element has a stop and / or a visually perceptible marking, so that the holding plate can either not be sunk deeper or the achievement of the predetermined depth is determined by the operator due to the visual impression.
  • the setting tool allows a sunk set the holding plate, so for example, has no interference geometries.
  • a depth is meant which goes beyond what can be achieved by mere compression of the insulating material, in particular a depth of more than 10 mm, measured from an insulating material facing bottom of the retaining plate.
  • the setting device has a contact element for engaging the retaining plate.
  • the retaining plate is supported by the setting tool when sinking into the insulating material, which means that the retaining plate does not deform when sinking, or at least not significantly. This in turn ensures that a uniform, improved setting behavior is achieved even with repeated setting operations with the setting tool with different substrates and insulation materials.
  • the abutment element bears in a radially outer region with a contact surface on the retaining plate.
  • the setting device rests with a the holding plate facing end side of the holding plate and that the contact surface is arranged in particular on the radially outer edge of this end face to the holding plate above all to support the outer edge.
  • the contact surface does not have to be closed, but may consist of several partial surfaces.
  • the contact surface is concavely curved, since it has been proven for the stability and production of holding plates that they are convex on their side facing the setting device. In this way, the setting tool can optimally cling to the retaining plate.
  • the concave shape is not necessarily continuous, but may for example also contain stages.
  • the outer diameter of the setting device in the region of the contact surface substantially corresponds to the retaining plate, in particular, the outer diameter is not greater than the diameter of the retaining plate. This causes on the one hand, that it does not interfere, which would cause additional forces when sinking into the insulating material, and on the other hand, that the retaining plate is supported outside the edge, so that the retaining plate is effectively relieved of the forces occurring when sinking.
  • the setting device has a rotational drive means for transmitting a torque to the fastening element.
  • a rotary drive can be used on the setting tool for driving. The driving is facilitated by the rotation, be it on the retaining plate or on the anchoring element.
  • a rotational drive means in particular acts positively with respect to the torque to be transmitted.
  • the geometries known from tools can be used, but also non-standardized geometries with pins, teeth, webs, grooves and the like. Also possible is a friction-engaging rotational drive means.
  • the setting tool has a first rotational drive means, which engages with pins or the like. In corresponding recesses in the retaining plate.
  • the setting tool has at least two rotational drive means, wherein a first rotary driving means directly on the holding plate and a second Rotational drive means can act directly on a screw of the fastener.
  • the second rotational drive means cooperates in particular with tool engagement means of the screw.
  • the two rotary drive means both the holding plate and the screw is rotated, which facilitates the sinking of the holding plate, without a torque between the holding plate and screw must act. The forces to initiate the required torques are thereby better distributed than in a mere initiation on the retaining plate or on the screw.
  • the setting device is preferably used flexibly such that it can be used either for the described sinking of the holding plate or for a surface-flush setting.
  • the invention proposes that the setting tool has a shaft element with a rotary driving means, which can act directly on a screw of the fastening element.
  • the shaft element can be exchangeably fixed relative to the contact surface in such a way that the rotary drive means points axially either in the direction of the contact surface or in the opposite direction. If it points in the direction of the contact surface, the setting tool can be used to countersink the retaining plate. If, on the other hand, it points in the opposite direction, then the setting device can be designed on the side opposite the contact surface in such a way that countersinking is not possible. The holding plate is then set flush with the surface.
  • the setting tool on a stop member to predetermine the depth when sinking.
  • the stop element is axially offset relative to the contact element, in a direction away from the contact surface.
  • the stop member also projects radially beyond the contact element.
  • the stop element projects radially beyond the retaining plate.
  • the stop element comes to rest on an outer surface of the plate-shaped insulating material outside the recessed area of the holding plate as soon as the predetermined depth is reached. The operator thus receives a clear signal that the setting process has been completed.
  • the setting device has a base body and a contact body.
  • the abutment body has the abutment element and the abutment element and can be fixed exchangeably in the axial direction relative to the main body.
  • the base body comprises the one described above Shaft element, so that the setting device can be used either for recessed or flush mounting of the holding plate.
  • the setting tool 1 shown in the figures is used to set a fastener 2 with a retaining plate 3, to attach a plate-shaped insulating material 4, here made of polystyrene, to a substrate 5, here made of wood.
  • the fastener 2 is a conventional insulation holder with a screw 6 made of metal as anchoring element 38 and a holding part 7 made of plastic.
  • the screw 6 has a wood thread 8 and a thread-free shank portion 9, to which a conical screw head 10 with a star-shaped tool holder 11 connects.
  • the tool holder 11 forms tool engagement surfaces 12.
  • the holding member 7 has on the one hand the retaining plate 3 and on the other hand, a sleeve 13.
  • the sleeve 13 connects centrally to the retaining plate 3 and points in the direction of insertion E of the fastener 2.
  • the sleeve 13 has a through hole 14 which tapers in the direction of insertion E at a contact shoulder 15. At the contact shoulder 15 of the screw head 10 is located.
  • the screw head 10 is thus arranged axially offset from the holding plate 3 sunk in the through hole 14.
  • the screw 6 extends with the unthreaded shank portion 9 through the narrower part of the through hole 14 and beyond the sleeve 13 with the wood thread 8.
  • the retaining plate 3 is circular, points a facing in the direction of insertion E flat bottom 16 and a slightly convex top 17 on. In radially outer third of the holding plate 3 has this distributed over the circumference a plurality of arcuate extending, elongated recesses 18 which penetrate the retaining plate 3 axially.
  • the setting tool 1 is largely rotationally symmetrical.
  • the main body 19 has a shaft element 21 with a star-shaped tool tip 22, which corresponds to the tool holder 11 of the screw 6. Regardless of the configuration, the tool tip 22 always points in the insertion direction when setting a fastening element 2.
  • the shaft element 21 is adjoined by a significantly larger outer thread section 23 and, in turn, by a radially protruding collar 24. With a significantly smaller diameter, the base body 19 terminates with a hexagonal shaft 25. Both the hexagonal shaft 25 and the shaft element 21 may be separate, replaceable components of the base body 19.
  • the main body 19 is shown here but as a single component.
  • On the male threaded portion 23 of the contact body 20 is screwed with a corresponding internal threaded portion 26.
  • the inner diameter portion 26 is part of an annular base portion 27.
  • the outer diameter of the base 27 substantially corresponds to the outer diameter of the retaining plate 3. From the base 27 extends in the direction of insertion E pointing annular support ring 28.
  • the support ring 28 has the same outer diameter as the base 27th serves as a contact element 29 for the retaining plate 3.
  • the support ring 28 has on its the holding plate 3 facing, in the insertion direction E front side a concave contact surface 30 which corresponds to the top 17 of the retaining plate 3, so that the retaining plate 3 at Setting flat against the contact surface 30.
  • the holding plate 3 is located radially further inside also on a flat end face 31 of the male threaded portion 23, which points in the direction of the retaining plate 3 (see FIG. 2 ). Also, this end face 31 thus serves as a contact element 29 for the retaining plate 3, wherein only in the radially outer region a concave contact surface 30 is arranged.
  • Between the end face 31 of the externally threaded portion 23 and the support ring 28 are from the base 27 of the contact body 20 distributed over the circumference several cylindrical pin 32 in the insertion direction E.
  • the pins 32 engage in the recesses 18 of the retaining plate 3.
  • the pins 32 are thus used first Rotational driving means 33, while the tool tip 22 serves as a second rotary driving means 34.
  • an enlarged diameter ring stage 35 which corresponds to the collar 24 in both the axial and radial dimensions, so that the collar 24 as a stop for the on the base body 19th screwed-on contact body 20 is used.
  • an annular disc-shaped stop member 36 which projects beyond the base 27 of the contact body 20 and thus the contact element 29 radially.
  • FIG. 2 is shown in three sub-figures (a, b, c) of the setting process with sunk mounting the holding plate 3.
  • the fastener 2 is placed in each case on the setting tool 1 as in FIG. 1 shown.
  • When placing the setting tool 1 is optionally slightly rotated relative to the fastener 2 until the pins 32 engage in the recesses 18 and the tool tip 22 in the tool holder 11 of the screw 6. Since the recesses 18 are arcuate and elongated, only a small rotation is necessary and ensures easy plugging.
  • FIG. 2a the screw 6 is already pushed by the insulating material 4 and the foremost part of the wood thread 8 already screwed into the substrate 5.
  • the sleeve 13 of the holding part 7 sits straight on a surface 5 facing away from the outer surface 37 of the insulating material 4.
  • the setting tool 1 was rotated.
  • the setting tool 1 is clamped to the hex shank 25 in a cordless screwdriver, not shown.
  • the rotational movement of the setting tool 1 is transmitted to the screw 6 and the retaining plate 3.
  • the torque transmission takes place independently, since the retaining plate 3 is not rotationally coupled to the screw 6.
  • the sleeve 13 of the holding part 7 is drawn into the insulating material 4, whereby it is displaced somewhat radially until the holding plate 3 rests with the bottom 16 on the outer surface 37 of the insulating material 4, as in FIG.
  • the holding plate 3 is sunk into the insulating material 4 by turning it further.
  • the insulating material 4 is thereby compressed axially.
  • the axial forces occurring here on the retaining plate 3 are thereby partially transmitted via the sleeve 13 to the screw 6, so that the screw 6 pulls the retaining plate 3.
  • the retaining plate 3 is also supported by the abutment element 29 and, in particular, in the radially outer region of the concave abutment surface 30 supported, if the operator exerts at least a small axial thrust on the setting tool 1. This causes the retaining plate 3 hardly deformed, which favors the breaking of the insulating material 4 on the circumference of the retaining plate 3.
  • the required torque remains relatively low and it always creates a very similar setting pattern.
  • the driving is continued until, as in Figure 2c illustrated, the stop member 36 comes on the outer surface 37 of the insulating material 4 to the plant.
  • the retaining plate 3 is thereby sunk with a defined depth T relative to the outer surface 37.
  • the setting device 1 can be deducted final and the holding plate 3 (not shown) with a Dämmstoffrondelle flush with the outer surface 37 are covered.
  • the contact body 20 of the setting device 19 can be unscrewed from the base body 19 and screwed back in the reverse axial direction, the base 27 comes to the collar 24 to the stop. In this way, when setting the stop member 36 to the holding plate 3, while the support ring 28 has in the opposite direction. Thus, the shaft member 21 is changeable relative to the contact surface 30 can be fixed. If the fastening element 2 is placed on the setting tool 1, then only the tool tip 22 comes into engagement with the screw 6, while the retaining plate 3 no positive rotary connection is formed. The holding plate 3 is in a plane on the stop member 36 and the male threaded portion 23 of the body 20 at.
  • FIGS. 4a and 4b the setting process is shown, the FIG. 4a essentially the FIG. 2a equivalent.
  • the holding plate 3 due to friction between the holding part 7 and screw 6 and between holding plate 3 and setting tool 1 until the illustrated state still rotate.
  • this rotation can come to a halt, which is irrelevant to the setting process.
  • the setting tool 1 is rotated as long and driven the fastener 2 so long until the stop member 36 in turn touches on the outer surface 37 of the insulating material 4.
  • the retaining plate 3 is then only very slightly recessed to its own thickness, set in the insulating material 4 and closes with its upper side 17 with the outer surface 37 of the insulating material 4th from.
  • the retaining plate 3 is thus set flush with the surface.
  • the insulating material 4 is only slightly compressed at the bottom 16 of the retaining plate 3.
