Description

The invention relates to a fixing dowel for fixing plate-like thin-walled components, such as plate elements, for example, to build a wall, floor and / or ceiling panel, wherein the fixing dowel can be inserted and fixed in a direction of insertion into a mounting recess of the component, a fastening anchor with a in the insertion direction extending central through-opening and with spreadable from a central longitudinal axis of the fixing dowel spreading elements for fixing the fixing dowel in the mounting recess and a strike pin and is designed for a turning of the turning bolt in the insertion direction into the through hole into an insertion position, in which the fixing anchor a certain target depth of Fastening recess has reached and from the positive and / or non-positive fixing of the fastening anchor in the mounting recess under the action of the egg stop bolt a radial spreading of the spreading takes place on the inside against the wall of the mounting recess in a mounting position inside.

Such a fixing dowel is for example from the WO 94/19613 known. The fastening anchor is formed here as an undercut anchor, including its spreading radially outwardly protruding projections have at the end, with which the fastening anchor engages under spreading of the spreading in the undercut. In particular, under normal working conditions on site, it often happens that this spread does not occur only when the proper insertion position is reached, but prematurely and thus without proper intervention in the undercut, so that the undercut anchor back cumbersome and time-consuming from the mounting recess must be removed.

The same applies to a in DE 20 2012 001 544 U revealed undercut anchors, in each case a predetermined bending point is provided here for easier spreading of the spreading elements of the same in the insertion direction, on which the spreading elements for engagement in the undercut are radially bendable.

In EP0336183A2 An undercut anchor is described in which the bolt is designed as a screw-in bolt with external thread, which is screwed into the mounting recess. Although a proper spreading of the spreading is possible by screwing, but screwing in the assembly is cumbersome and time consuming.

Furthermore, the WO2013 / 120746 a fixing dowel removed, in which the spreading elements each have a radially outwardly extending cutting projection to the insertion direction with a radially outwardly disposed cutting edge, so that the cutting projection in the mounting position radially intersects positively in the inner wall of the mounting recess. Although this cutting and setting of the fixing dowel could theoretically also be done before the proper insertion position with the disadvantage that these fixing dowels then protrude different distances from the mounting recess and not properly against the component to be fastened.

An object of the invention is, therefore, to provide a generic fixing dowel, which effectively counteracts premature spreading of the expansion elements during insertion of the fixing dowel in the mounting recess.

The stated object is achieved by the features of claim 1. Advantageous developments are described in the subclaims. The stated object is already achieved in the simplest embodiment in that the fixing dowel has a retarding device with one or more delay elements which is or are each, the insertion of a relative movement between at least two for driving the fixing dowel into the insertion position necessary relative to each other movable parts of the fixing dowel, such as the impact pin relative to the fastening anchor and / or the expandable expansion elements relative to each other, and / or to delay this relative movement per se.

This delay may, for example, relate to the axial relative sliding movement with respect to the direction of insertion and / or the insertion of the same between the fastening anchor and the impact bolt. It can be retarded during insertion of the impact pin insertion of Aufspreizens the spreading and / or the spreading of the same radially outwards. By means of the deceleration device, the beginning of an axial relative sliding movement between the fastening anchor and the impact bolt is delayed when the impact bolt is driven into the passage opening of the fastening bolt and / or the axial relative sliding movement between the same is decelerated or slowed down. This deceleration refers to the relative sliding movement of a conventional fixing dowel without a retarding device.

In each case, these retardation measures cause the fastening anchor to be accelerated to its insertion position and to take it up before the impact pin acts on the spreading elements in an expelling manner. This effect can already be achieved by one of the delay measures. The acceleration of the mounting anchor may also be so great as a result of the deceleration of the braking that the relative sliding movement between the fastening anchor and the impact bolt can be minimized or zero. The extent to which the two deceleration mechanisms, deceleration of the beginning of the relative movement and deceleration of the relative movement, act on the relative movement between the respective components, can be adjusted by the design of the deceleration device, ie in particular the design, the number and the arrangement of the delay elements ,

The specific insertion position may be predetermined in that the fastening recess is a blind bore with a bottom on which the fastening anchor is seated in the front side in the insertion position. Alternatively, the attachment recess can have a shoulder serving as a stop, as is possible, for example, in the case of a stepped bore, against which the attachment anchor abuts in the insertion position, for example resting on the end side. The bottom of the blind bore or the step of the stepped bore mark the prescribed nominal depth for the fixing dowel.

As usual, the fastening anchor and the impact pin can each have at least one sliding surface parallel to the insertion direction, at which they are arranged axially displaceable relative to each other. The sliding surfaces may each extend parallel to the insertion direction. As usual, the opening cross-section of the passage opening of the outer contour of the turning pin can be at least largely adapted.

In particular, the delay element can be formed as a survey, such as projection, protrusion or thickening. The retarding member may also include as one or more friction increasing portions of the sliding surface. Structurally simple, the survey can be arranged at least on one of the sliding surfaces. The survey may protrude over this sliding surface to the associated sliding surface of the respective Gleitpartners. The elevation element may project beyond this sliding surface with respect to a plane perpendicular to the insertion direction. The bump element may extend away from this sliding surface.

The elevation itself can form an insurmountable barrier. Overcoming the barrier can be done by elastic deformation of the sliding partner in the survey or the projection. By these deformation forces the beginning of a relative movement between the two sliding partners can be delayed and / or the relative movement is hampered due to increased friction, the mechanism can cause the fastening anchor leading to the impact bolt reaches the prescribed insertion position.

The elevation element with respect to the associated sliding surface can be formed as a convex protrusion, in particular as a knob, as a projection extending radially to the associated sliding surface or as a thickening. Alternatively, to inhibit the sliding movement of the sliding partners, at least one axial portion of the sliding surfaces or an axial portion extending preferably over the entire sliding path of the sliding partners, fastening anchors and impact bolts, with a greater sliding resistance, for example by larger sliding surfaces and / or adjustment a certain roughness of the sliding surface or the sliding surfaces, be provided.

The survey of a sliding partner may extend in the installed position in each case to the sliding surface of the other sliding partner. It may also be provided on both mutually associated sliding surfaces of the sliding partners surveys. It can be arranged on a sliding surface of the fastening anchor and / or on a sliding surface of the turning pin in each case at least one elevation element. Arranged on the sliding surface of the fastening anchor, the projection may extend radially inwards. Arranged on the sliding surface of the turning pin, the projection may extend radially outward. The projection of the survey on the sliding surface associated therewith can be, for example, in the order of ≥1 / 24 to ≤1 / 6 of the diameter of the turning pin in the section with which it is arranged in the mounting position in the mounting recess. However, these figures are purely exemplary, since the optimal geometric dimensions for use of the elevation element and their relationships to the geometric dimensions of the attachment anchor and / or the impact pin can vary.

As usual, the impact pin may have a shaft to its guide in the mounting recess and a rear end portion in the insertion direction for spreading the spreading elements. Preferably, at least one elevation in the insertion direction is arranged behind and / or in front of the shaft in each case.

For assembling fastening anchors and impact bolts, the fastening recess may have a conical constriction arranged at the front in the insertion direction and / or, in the case of an arrangement of the elevation element radially inward in the attachment recess of the attachment anchor, the impact pin in the insertion direction arranged at the front conical constriction. The narrowing serves as Aufgleitrampe. The elevation element can slide on the ramp and preferably clamp in the insertion direction end of the ramp between mounting anchor and impact pin. Thus, the fastening anchor can be performed without or due to delayed relative movement relative to the impact bolt in its insertion position and then follow the impact bolt under radial pushing away the expansion elements against the wall in the mounting position. The disadvantage could possibly vary the exact location of the clamping in the mounting recess to a small extent.

Advantageously, the survey or the surveys in the insertion of the impact pin strike against a designated stop and / or lock on the same. The stop or latching is advantageously designed to delay the onset of the relative sliding movement between it and the fastening anchor when the strike pin is turned. The stop can be formed, for example, by guiding the elevation in an axial bag-like guide trough which ends in the insertion direction as a stop, forming an end-side side wall pointing in the axial direction.

Alternatively, the mounting recess, for example, designed as a stepped bore, by forming a reduction in the diameter in the insertion direction as a stop effective paragraph, wherein the survey is conducted against the stop. The firing pin can advantageously have a cross-sectional taper arranged in the insertion direction to form a retardation element. This can be an annular shoulder ( 48 ) train. The outer diameter of the annular shoulder may be slightly larger than that of the through hole of the fastening anchor.

The occurring during the relative movement between the elevation elements and the inner wall of the mounting recess friction and thus delay the relative movement can be adjusted for example on the number, arrangement and / or shape of the elevation elements and material pairing of the sliding.

The options described above relate essentially to the arrangement of the survey radially outward on the impact pin. Of course, the positioning of the elevation elements on the inside of the mounting recess is also possible in the reverse arrangement. The elevation elements can also be arranged on the inside of the fastening recess and radially on the outside of the striking pin. The stop may be formed by an annular or preferably a plurality of partially annular shoulders. The elevation or barrier may protrude radially to the shoulder. The stopper may limit an insertion path of the attachment anchor into the attachment recess.

Advantageously, the survey or the surveys can be arranged on the impact pin. To stabilize the shape and stable fixing of the fastening anchor in the fastening recess, at least some of the, preferably all elevations in the fastening position can in each case latch into a latching opening provided on the respective sliding partner. The Verrastungsöffnung can be adapted to each associated survey. For easier entry of the survey into its associated Verrastungsöffnung or loosening from the same, the survey may have a sliding against the insertion direction Abgleitschräge. Of course, the reverse arrangement of the survey or the surveys are radially inward in the through hole of the mounting anchor and the arrangement of the surveys on the mounting anchor and the impact bolt also possible here.

Advantageously, the survey can be formed by a projection which is preferably formed as an annular projection with a ring plane or cross-sectional plane perpendicular to the insertion direction. The survey may also include a plurality of projections, which are preferably arranged axially at the same height and circumferentially equally spaced. The projection or at least some of the projections may each be formed with rounded edges. For easier initiation of the relative movement of the projection or the projections may each have an effective in the insertion direction Aufgleitebene.

As advantageous is a knob-like shape of the projection with a Kalottenform, in particular Kugelkalottenform, or viewed a cylindrical shape with kreissegmentartigem cross-section, wherein the cylinder axis is advantageously arranged perpendicular to the insertion direction, so that the rounding point in or against insertion direction. Advantageously, the survey in both cases with respect to the direction of insertion comprises a Aufgleitschräge and a Abgleitschräge. With regard to the insertion direction, the slide-on slope in the insertion direction leads radially inwards and the slide-off slope in the insertion direction radially outward.

Advantageously, the survey can serve as a stop in itself in the ready position by the impact pin in this position in Insertion direction engages with a direction of insertion rear portion in the opening of the fastening anchor and abuts with the survey at the opening edge of the through hole of the fastening anchor.

In an advantageously simple embodiment of the fixing plug, at least one of the delay elements, in particular a plurality of delay elements may each be designed as a predetermined breaking point. About this or this may be necessary for the insertion of the fixing dowel relative to each other movable parts of the fixing dowel, such as turning pins relative to the fastening anchor and / or the expandable expansion elements relative to each other, connected to each other.

Delay elements may thus, at least in part, each as a survey that protrudes from a sliding surface of a sliding partner to this sliding surface associated sliding surface of the other sliding partner out, and / or each as a predetermined breaking point, the two or more when driving the fixing dowel necessary relative to each other movable parts firmly together.

Advantageously, at least one predetermined breaking point can be characterized by a reduced cross section, at which a break occurs at a certain mechanical load, while in the environment to the predetermined breaking point no breakage failure occurs. The predetermined breaking point can be realized, for example, at a point of contact or via a connecting web or bridge between the corresponding components of the fastening plug which are necessarily movable relative to one another. For this purpose, the connecting web or the bridge can have at least one section with a reduced cross section as a predetermined breaking point in which at least two of these components touch each other. On the size of the cross-sectional area, a force can be set, under the action of the respective predetermined breaking point functionally fails, i. breaks.

Thus, a firm and thus position stabilizing connection between the relevant components of the fixing plug can be created on the predetermined breaking points. It can thus be kept in the supply position in a correct position to each other arranged the relevant components of the fixing dowel. The connection can be cohesive.

With the predetermined breaking points as joints of the entire fixing dowel may be formed as a one-piece injection molded part, in particular made of plastic. Thus, the fixing dowel production side already created and stored with the correct supply position. The predetermined breaking point can also serve as a seal whose break or integrity indicates whether the respective fixing dowel has already or not been used. Impact bolts and fastening anchors can each be designed as a one-piece injection molded part, in particular made of plastic.

The predetermined breaking points can be designed so that they fail to function at the latest when striking the turning pin in the fastening anchor when the fastening anchor has reached its insertion position almost or completely. An earlier breaking of the predetermined breaking points, for example, be useful if, as described above, for example, by means of increased friction between the sliding still further acting in the insertion direction forces are to be introduced into the fastening anchor to bring him to the insertion position before the spreading of the expansion elements done by the impact pin.

The rear end region of the fastening anchor which is in the insertion direction can, as usual, be longitudinally segmented into individual at least two, preferably four, spreading elements. The spreading elements can be designed to be spreadable or spreadable at least essentially radially relative to the insertion direction. You can limit the passage opening and at least in the mounting position are circumferentially spaced from each other via a slot. As usual, the spreading of the spreading elements can take place in that the impact pin urges in the passage opening between the spreading elements and thereby spreads radially outwardly. Preferably, the spreading elements are at least equal to the basic shape.

Advantageously, it can be provided that with respect to the insertion direction in the circumferential direction adjacent expansion elements for delaying the onset of spreading the spreading elements, each at least over a predetermined breaking point or alternatively a plurality of circumferentially and / or axially spaced predetermined breaking points are interconnected. The relative movement between the fastening anchor and impact bolt is inhibited. The kinetic energy of the turning pin in the insertion direction is correspondingly transmitted to the fastening anchor. This can be prevented that the spreading elements are prematurely spread and thus fix the fixing dowel in a position on the way between the ready position and mounting position.

Advantageously, the adjacent expansion elements can alternatively or additionally be connected to one another in the insertion direction in front and / or in the center via predetermined breaking points. In terms of injection molding less advantageous, the respect Center longitudinal axis diametrically opposite spreading elements, for example, via a connecting web and / or all spreading radially inward, for example via a preferably thin disc or star be connected to each other, wherein the connecting web and disc each serve as a predetermined breaking point.

In an advantageous development of the fastening plug, the impact bolt can be arranged axially aligned in the supply position with respect to the insertion direction to the fastening anchor and by a certain amount in the through hole. In particular, the impact bolt can be arranged connected to the fastening anchor via a predetermined breaking point or via a plurality of predetermined breaking points circumferentially and / or axially spaced from one another. In this correct position for striking the impact bolt can be firmly connected in particular exclusively via the predetermined breaking points with the fastening anchor. The impact pin can thus be held captive to the fastening anchor on the same. As a result of the connection via the predetermined breaking points, the fastening anchor is accelerated over the impact bolt in the direction of its correct insertion position. A relative movement between the anchor and anchor bolts can only be done with failure of the predetermined breaking points. This can occur, for example, only when the fastening anchor has reached its insertion position.

To stabilize the position of the predetermined breaking point firmly connected to each other two components, impact pin and fastening anchor, it can be provided that the aforementioned specific amount a height up to 80%, up to 40% or up to 20% of the actual axial length of the fixing dowel in the Has attachment position.

Advantageously, the fastening anchor can be axially reduced to the end region having the spreading elements. This end region can be firmly connected via the predetermined breaking points in the direction of insertion to the end region of the fastening anchor. Greater stability can be achieved by arranging the impact bolt in the deployment position at most over the length of its shaft in the direction of insertion into the passage opening. To improve the stability of the impact bolt can be connected in the direction of insertion behind and in the direction of insertion front over predetermined breaking points with the fastening anchor.

In a particularly advantageous alternative solution of the problem set in the introduction, the fastening anchor can be designed to be longitudinally segmented over preferably the axial length with which it is projecting into the fastening recess in the fastening position. The axial length refers to the central longitudinal axis. The fastening anchor can be split into segments extending in the direction of insertion. The segmentation may be continuous, i. continuously and without interruption in the axial direction, done. This segmentation may also include the segmentation of the rear end region to the spreading elements. Simplifying the production, the fastening anchor can be formed longitudinally segmented over its at least almost almost entire axial length. The longitudinal segmentation may extend over the entire attachment anchor. The segmentation may be formed so that the predetermined breaking points between the firing pin and segments equal to a seam extend over at most the axial length of the fastening anchor, is arranged protruding with the fastening anchor in the mounting position in the mounting recess.

The passage opening may be limited by the segments. The segments may be circumferentially spaced by a slot, so that the passage opening is formed by the slots radiating radially outwardly widening. The opening side surfaces delimiting the passage opening and in particular the opening side surfaces delimiting the slots can form the sliding surfaces for discharging on the impact bolt. The segments can each preferably preferentially be firmly connected to the impact bolt via predetermined breaking points.

In a particularly advantageous alternative solution to the problem set out above, the impact bolt can have a star-like or beam-like cross-section, preferably perpendicular to one another, at least in a rear region in the insertion direction, which is provided for engagement in the passage opening in the fastening position. The ends may be rib-like or wing-like in their three-dimensional form. (In the following, ribs always mean wings.) The ribs may be plate-like. Whose rib side surfaces pointing in the circumferential direction can be formed, at least predominantly, as sliding surfaces for slipping on the respective associated sliding surfaces of the fastening anchor. The sliding surfaces can thus be radial-axial side surfaces. Furthermore, the ribs may be formed at least substantially the same and circumferentially equally spaced from each other with respect to the central longitudinal axis. The fastening anchor may have a cross-shaped cross-section with four preferably equal lengths as ribs. This embodiment makes it possible to form a larger overall sliding surface compared to a cylindrical basic shape the fastening anchor and thus the passage opening. Depending on requirements, for example, by providing a recess in the respective sliding surface, only one or more sections of the rib side surface and / or the opening side surface can be used as a sliding surface.

The ribs can pass axially through the slots. The ribs can each be connected to the circumferentially adjacent segments via the delay elements formed as predetermined breaking points. This can preferably be done in the areas in which two ribs converge radially inward.

In another embodiment of the fixing dowel this may have a cylindrical, in particular circular cylindrical basic shape. The passage opening can be limited by a cylindrical inner wall. The impact pin may have a cylindrical outer surface at least in an insertion direction in the rear portion which is provided for engagement in the through hole. Inner wall and lateral surface can rest in the ready position slidable together. Instead of the cylindrical shape, a shape with the geometries of a preferably straight prism, this preferably with the same Prismaseitenflächen, or with a polygonal cross section are preferably used with the same sides.

Mechanically favorable, the delay elements of at least one category, i. that the elevations or the predetermined breaking points, and / or groups of delay elements in each case at least one category with respect to the direction of insertion in each case radially and / or axially spaced from each other. The delay elements may be arranged axially symmetrically with respect to the central longitudinal axis.

Usual, but not absolutely necessary for the invention, the fixing plug can have a resilient abutment. By means of the abutment, the fixing plug can be supported in the fastening position in the insertion direction at the front on a component to be fastened and / or on a preferably fixed between abutment and component to be fastened Agraffe or similar component for connection of a further construction, preferably spring preloaded.

This abutment may have struts. These can each extend approximately radially or exactly radially, preferably in an opening in the direction of arch form away from the fastening anchor and supported in the insertion position with your free ends on the Agraffe or a similar component under spring preload. In increasing the rigidity, the arcuate shape can be formed by at least two linear sections at an angle to each other. The struts can act equal to a clamped leaf spring or flat spring. By using individual struts with respect to the insertion direction relative unevenness of the surface can be compensated, at which the struts are supported with their respective free end. For easier sliding of the free ends of the struts in the spring-elastic bracing of the fixing dowel in the same insertion position, the free ends may have an open against insertion arch form. The leaf springs may be formed as a rectangular leaf spring or trapezoidal leaf springs. It can be provided at least three struts, preferably four struts. The struts can, with respect to the insertion direction, circumferentially equally spaced and / or arranged at the same height. This structure allows a displacement for position correction of Agraffe after installation of the fixing dowel with respect to a plane perpendicular to the insertion direction.

In particular, the struts can be resiliently biased in the mounting position of the fixing dowel against the component to be fastened. The struts may each have a radial length, the amount of which may be, for example, one to two times, four times or more of the diameter of the mounting recess. They may extend over a radial length that is at least equal to or about equal to half the axial length, preferably at least equal to or about equal to the axial length of the fastening bolt. For ease of releasability during injection molding, the struts can be designed to be perpendicular to a single longitudinal plane extending and resiliently deflectable. The struts may extend from the radial outside of the expansible anchor.

For fixed fixing of the fastening plug in the fastening recess, at least most of the expansion elements can each have a radially outwardly pointing undercut projection. This can be designed for positive engagement in an introduced in the wall of the mounting recess undercut in the mounting position inside. The undercut projection may be formed adapted to the undercut. Such an undercut is in WO 94/19613 and DE 20 2012 001 544 U described, to which expressly referred. According to W02013 / 120746 can the projection as to the insertion direction radially outwardly extending cutting edge projection with a radially outwardly facing cutting edge for the positive cutting of the cutting edge projection in the Have wall of the mounting recess. However, the invention is by no means limited to this Befestigungsdübelart. It also includes other types of fixing dowels with fixing anchors, impact bolts and over the impact pin spreadable spreading elements.

If a reference for example to 3 done, so are the associated 3a-3d meant. In some figures, directional arrows 4b; 5c; 5c; 6c; 6d or 7b drawn, the view direction to the respectively associated 4b ; 5c ; 5c ; 6c ; 6d ; 7b specify. In the 1 to 7 are each in different views and detailed view different embodiments of a fixing dowel 1 for fixing plate-like thin-walled components B one of which is shown schematically and dashed in FIG 1 is shown. In the embodiment of the fixing dowel 1 according to the 1-3 and 7 are each the impact pin 3 and the fastening anchor 2 each and in which according to 4-6 is the entire fixing dowel 1 formed as a one-piece plastic injection molded part.

The fixing dowel 1 is in an insertion direction e in an in 1 exemplified dashed mounting hole A of the component B can be used and fixed. The fixing dowel 1 has a fastening anchor 2 with one in the insertion direction e extending central passage opening 21 and with four here from a central longitudinal axis l of the fixing dowel 1 away spreadable spreading elements 22 for fixing the fixing plug 1 in the mounting recess A of the component to be fastened B on. The spreading elements associated with an embodiment 22 of the fixing dowel 1 are circumferentially equally spaced apart from each other in all embodiments shown in the figures. The fixing anchor 2 is in 2 shown in a detail view, wherein the fastening anchor 2 as in 1 , furthermore in the 3 to 6 four spreading elements 22 having. In the embodiment of the fixing dowel 1 according to 7 are in a constructively minimized embodiment only 2 spreading elements 22 intended. The number of spreading elements 22 however, is not limited to two or four, but may be three or more than four. The spreading elements 22 Each embodiment shown in the figures of the fixing dowel 1 are at least substantially the same. Further, a knock-in bolt 3 provided, which can be taken in a known manner in a relative movement to the fastening anchor under sliding at the passage opening in the same.

The fixing anchor 2 is by the impact pin 3 in the insertion direction e in the passage opening 21 in an in 4e placed by way of example and dashed insertion position, in which the fastening anchor 2 in a prescribed nominal depth t the mounting recess A touches down. The target depth t will be used according to the 1 shown example through the floor G the mounting recess A Are defined. The insertion position of the turning pin 3 is according to 4e is (but not necessarily) somewhat fictitious in that, as will be made clear below, the wrapping operation is via a retarder according to the invention 4 is significantly influenced. In the insertion position of the fixing anchor 2 should the spreading elements 22 still in their ready position, so be arranged undocked.

In further progress, the impact bolt 3 along the central longitudinal axis l in the insertion direction from the insertion position into its fastening position in between the spreading elements 22 crowded. The spreading elements 22 are spread radially outwardly relative to each other in a relative movement and here in each case engage with an undercut projection which is arranged at the end and extends radially outwards 23 in one in the mounting recess A provided undercut H engage in a form-fitting manner. In this respect, the fastening dowels shown in the figures are 1 each formed as an undercut anchor, which is not necessary for the invention. While in the 1-2 illustrated fastening anchor 2 with already radially outwardly pivoted expansion elements 22 are shown in the rest 4-6 the spreading elements 22 shown in the ready position in which this, so that they are in the mounting recess A can be used under cross-sectional tapering of the fixing plug 1 bent in a known manner end radially inward. The fixing anchor 2 braced in the attachment position via an elastic abutment 5 in the insertion direction e in front here over an agraffe C on the component to be fastened B from.

According to the invention, the fixing dowel 1 , for delaying the use of the axial relative sliding movement between fixing anchors 2 and impact bolts 3 when driving in the impact bolt 3 in the passage opening 21 and / or for delaying this relative movement per se, the delay device 4 with a delay element 41 or, as provided herein, with multiple delay elements 41 on. As shown below, they may have the task of delaying onset of the spreading of the spreading elements.

The fixing anchor 2 and the impact pin 3 each have at least one parallel to the direction of insertion for slidable abutment e extending sliding surface 24 ; 31 on. Easy to manufacture, here are only on the sliding surface 31 of the knock-in bolt 3 several delay elements 41 each in the form of a survey 42 intended. The assessment 42 protrudes over this sliding surface 31 of the knock-in bolt 3 to its associated sliding surface 24 of the fixing anchor 2 out in front. It is designed to be an insurmountable barrier.

This is especially easy in the 1-3 illustrated embodiment of the fixing dowel 1 removable. Here are the delay elements 41 axially at a height and, up to 3c , circumferentially equally spaced from each other. According to 1 are the delay elements 41 each as a lead 43 formed, wherein, as indicated by a dotted line drawn, the outer diameter d1 of the fixing anchor 2 in the place of the projections 43 slightly larger than the inside diameter d2 the passage opening 21 is. The impact bolt 3 is what is not shown here, in the ready position as far as in the through hole 21 introduced that he with the protrusions 43 in the insertion direction at the front at the opening edge of the passage opening 21 rests. As a result, when turning the felling bolt 3 to the insertion position, first, the onset of relative movement between the strike pin 3 and fixing anchors 2 delayed and also the fastening anchor 2 accelerated towards the deployment position. The relative position between impact bolts 3 and fixing anchors 2 stays unchanged. In further progress, the passage opening 21 extended radially, so that the fastening anchor 2 in the passage opening 21 slips into it, but due to the protruding projections 43 the sliding friction between the sliding partners is increased so far that the fastening anchor 2 at least more towards the insertion position than the impact pin 3 is accelerated. Overall, this can be the anchor fastening 2 far in front of the impact bolt 3 reach the insertion, so that the spreading of the spreading 22 only in the insertion position of the fastening anchor 2 can be done. For gentler introduction of the impact energy, as indicated by dashed lines, the passage opening 21 under formation of a Aufgleitschräge 431 against insertion direction e be formed conically widened.

The influence on the relative movement depends on the number and design of the delay elements 41 from. Therefore are purely exemplary and without wishing to be limited to, in the 3a to 3d further possible embodiments of the delay elements 41 shown. Here are the in the 3a-3b projections 43 each partially circular ring or part-ring-shaped, wherein the projections 43 according to 3a circumferentially smaller than the according to 3b are. According to 3c is an annular projection 43 intended. The larger the delay elements 41 are, the higher the corresponding delay. According to 3d have the delay elements 41 a knob-like training here in the form of a hemispherical calotte, which, similar to the above-described conical extension of the passage opening 21 , a Aufgleitschräge 431 forms. The passage opening 21 is executed here as a stepped bore. It has a paragraph 25 on, against which the projections 43 strike on the underside when the impact pin 3 his attachment position in which he the spreading elements 22 as has spread spread radially outwards, has reached.

The abutment 5 here four is from the central longitudinal axis l of the fixing dowel 1 away struts 51 on. The struts 51 are formed like a leaf spring. They extend from the attachment anchor 2 tongue-like radially outward. The struts 51 each go from the radial outside of the attachment anchor 2 from and have one to the passage opening 21 open wide sweeping approximately arcuate course. For tighter connection to the fastening anchor 2 and increase their Spring stiffness are the struts 51 each in their approach to the radial outside of the mounting anchor 2 through a stiffening 52 strengthened. It connects the struts associated with it 51 namely at its approach with the fastening anchor 2 .Constructively simple is this stiffening 52 formed rib-like. It is perpendicular to the respective associated struts 51 arranged. The in the 1-3 illustrated fixing dowel has a circular cylindrical basic shape. The passage opening 21 is bounded by a cylindrical inner wall, which is the sliding surface 24 forms. The impact bolt 3 has a shaft 32 with a substantially cylindrical surface on which the sliding surface 31 of the knock-in bolt 3 forms. To initiate the impact energy in the impact bolt 3 has the impact pin 3 in the insertion direction e an impact head in front 33 on. For easier removal of the knock-in bolt 3 by levering the impact head 33 a much larger diameter than the shaft 32 of the knock-in bolt 3 on.

In the in the 1 to 8th shown embodiments of the fixing dowel 1 has the fixing anchor 2 one in Einsetzrichtung e rear end area 26 with the spreading elements 22 on. Furthermore, the fastening anchor comprises 2 one in Einsetzrichtung e front end area 27 with cylindrical surface for guiding the fixing dowel 1 in the mounting recess A ,

The in the 4-6 illustrated embodiment of the fixing dowel 1 differ from the according to 1-3 in particular in that the shank 32 of the knock-in bolt 3 completely different. Furthermore, the delay device 4 here additionally completely differently formed delay elements 41 namely in the form of predetermined breaking points 44 having. The predetermined breaking points 44 are here characterized by a relation to an environment reduced cross-section, at which the predetermined breaking occurs under mechanical stress. It should be noted that such predetermined breaking point 44 in the same function also in the training form of the fixing dowel 1 according to the 1-3 can be used.

The predetermined breaking points 44 connect to the installation and fixing of the fixing plug 1 in the mounting recess A necessary relative to each other movable parts, such as the impact pin 3 relative to the fastening anchor 2 and here also the spreading elements 22 relative to each other, whereby the entry of the relative movement of these parts is delayed by the predetermined breaking points. Similar to the survey 42 trained delay elements 41 according to the 1-3 is also here causes the fastening anchor 2 safely reached the insertion position before the impact pin 3 between the spreading elements 22 to spread the same urges.

According to the 4-6 the impact pin protrudes 3 in the staging position by a certain amount b in the passage opening 21 into it and is at her alone about breaking points 44 connected and fixed. The higher the amount b is, the more stable this arrangement proves during the wrapping process of the fixing dowel 1 ,

Like all embodiments shown here by way of example, the fastening anchor is 2 in a direction of insertion e rear end area 26 under formation of the spreading elements 22 longitudinally segmented through slots 28 are separated from each other. According to the 4-6 are the circumferentially adjacent spreading elements 22 However, to delay the onset of their Aufspreizens at the level of their undercut projections 23 each as a predetermined breaking point 44 trained connecting bridge 441 connected with each other. The connecting bridge 441 bridges the respective slot 28 here almost completely.

Due to the longitudinal segmentation in four spreading elements 22 becomes the passage opening 31 through the slots 28 opened laterally and thus, because of the segmentation here in four spreading elements 22 , a cross-shaped opening cross section. In adaptation to this opening cross section is the impact pin 3 here about the axial length of its shaft 32 rib-like with here four ribs 34 educated. These ribs 34 pointing in the circumferential direction u pointing here a total of eight rib side surfaces 35 on. These serve at least partially as a sliding surface 31 to the sliding of the turning pin 3 at the passage opening 21 ,

According to the 4-6 However, this longitudinal segmentation extends, inter alia, because of easier demoulding during injection molding, here over the entire axial length of the fastening anchor 2 , ie also a front end region in the insertion direction 27 with cylindrical lateral surface for guiding the fixing dowel 1 in the mounting recess A , As a result, the fastening anchor breaks down 2 in here four segments 29 , However, these are in each case in two axially spaced-apart circumferential regions over predetermined breaking points 44 with the rib side surfaces 35 of the knock-in bolt 3 connected. As in particular the detail view according to 4c Removable, this connection is made with the predetermined breaking points 44 in the corner area, in which the rib side surfaces 35 circumferentially adjacent ribs 34 converge.

To further stabilize the relative position of fixing anchors 2 and impact bolts 3 are, in the amount of insertion direction e pointing end of the front end portion 27 , the embodiment according to 5a-5d the circumferentially adjacent segments 29 via a simple connecting bridge 441 as a predetermined breaking point 44 connected with each other.

According to the 6a-6d are the segments 29 at the same height and here over it in the direction of the struts 51 extending connecting webs 441 as predetermined breaking points 44 with rear end section 36 of the impact bolt 3 firmly connected. The better mold release during injection molding are the segments 29 in pairs and only on one side with the impact bolt 3 connected. The impact bolt 3 engages in its ready position stabilizing position as far into the passage opening 21 of the fixing anchor 2 one that he has with his rear end section 36 at about height in the direction of insertion e to or before the start of the spreading 22 ends. He is thus placed in the insertion position practically in a waiting position, from which he after a successful break of it in its relative movement to the fastening anchor 2 inhibiting predetermined breaking points 44 on a shorter way and thus much faster than according to 4 and 5 for engagement between the spreading elements 22 comes. For easier spreading, this indicates in the insertion direction e end provided free end of the mounting anchor 2 a cruciform thickening on.

In the embodiments according to the 4-6 has the impact pin 3 on each of its rib sides 35 as a delay element 41 a survey 42 on. This is as a lead 43 with slanted slope 431 and sliding slope 433 educated. The lead 43 go over these slopes 431 ; 433 in the insertion direction e seamless, ie without the formation of a body edge, in the respective rib side surface 35 above. In 4a are dashed lines to the fictional boundary of the projections 43 located. The projections 43 each extend with respect to the associated sliding surface 31 in approximately radial direction r and have a circular segment-like cross-section. Such as the 4a-4b removable, points each rib 34 on both sides of the ribs 35 one survey each 42 in the form of the projection 43 on. These then two projections 43 are arranged axially at a height. These two projections 43 can form a group. They each form a thickening 45 the respective rib 34 with, up to 6 , approximately circular cross section. The thickening 45 a rib 34 as well as an associated detent opening 291 for locking the thickening 45 , is in an alternating sequence to those of the two circumferentially adjacent ribs 34 arranged offset axially. This aligns the projections 43 two radially aligned ribs also radial.
