Description
Adhesive anchor for insertion into a lightweight building panel The present invention relates to an adhesive anchor having a screw-in channel for a fastening screw for insertion into a lightweight building panel which comprises a first and second cover panel made of wood or wood-like material, and an interposed center layer in a honeycomb structure, wherein the adhesive anchor can be fixed in the lightweight building panel in the mounted state by means of an adhesive and penetrates a bore in a cover panel and rests on the cover panel opposite the drilled-through cover panel with a front end thereof, and is positioned flush inside the bore with the other end thereof.
Adhesive anchors of the kind mentioned above are known and are used to enable the fixing of fitting parts or the like also to a lightweight building panel, with the loads in the connection area usually being static and relatively low.
The present invention is based on the object of providing an adhesive anchor of the kind mentioned above which also enables the secure connection of components in lightweight building panels which are exposed and highly loaded both dynamically as well as statically, especially the secure connection of a table-leg of a lightweight building panel used as a table top.
This object is achieved in accordance with the invention in such a way that the front end resting on a cover panel has a support edge protruding in the direction of the longitudinal axis of the adhesive anchor, and the adhesive anchor is provided with flow channels which rise from said front side and open into radially extending discharge openings in the region which rests flush within the bore.
As a result of the fact that the adhesive anchor is provided with a support edge in its front region resting on the cover panel and a front area which is set back in relation to said support edge, virtually the entire diametrical area of the adhesive anchor can be used for tightly gluing on the non-drilled cover panel. As a result of the possibility to provide an adhesive starting from here up to the upper section on the circumferential side of the adhesive anchor, this upper region which is disposed in the bore in the mounted state can be glued additionally in the bore, thus achieving extremely high stability of the adhesive anchor in the mounted state.
Since the screw-in bore is only used in the adhesive anchor in accordance with the invention to screw in a fastening screw, this screw-in bore can be dimensioned under consideration of the material employed for producing the adhesive anchor in such a way that the secure automatic cutting in of the fastening screw within the adhesive anchor is ensured. This measure too considerably increases high strength and stability of a desired connection.
Further features are the subject matter of sub-claims.
Embodiments of the invention are shown in the enclosed drawings and will be explained below in closer detail, wherein:

The drawings show a total of four different embodiments of adhesive anchors in accordance with the invention, with these adhesive anchors being provided consistently with reference numeral 1.
Figs. 1 to 7, 8 to 12 and 13 to 16 each show a two-part adhesive anchor 1, whereas the embodiment according to Figs. 17 to 30 shows a one-piece adhesive anchor 1.
Such an adhesive anchor I is generally determined for being inserted into a lightweight building panel which is designated in its entirety with reference numeral 2.
The lightweight building panel 2 consists in the known manner of a first and second cover panel 3, 4 and an interposed center layer 5 which has a honeycomb structure in the known manner. For reasons of clarity, the more detailed view of this honeycomb structure in the region of the center layer 5 has been omitted.
The two cover panels 3 and 4 are preferably made of wood or a wood-like material.
Every adhesive anchor 1 is provided with a screw-in channel 6 which is used for accommodating a fastening screw 7, by means of which a table-leg 8 shall be fastened for example to a lightweight building panel 2 which is used as a table top.
In order to ensure secure fixing of the table-leg 8 which can be subjected both to high static and dynamic loads, it is very important that an adhesive anchor 1 can be fixed in a very secure manner within the lightweight building panel 2.
In order to achieve this goal, it is provided in all adhesive anchors 1 which are inserted through a bore 9 in one of the cover panels 4 into the lightweight building panel 2 and rest on the inside of the other cover panel 3 opposite of the bore 9 that the front end resting on the cover panel 3 comprises a support edge 10 protruding in the direction of the longitudinal axis of the adhesive anchor 1, so that a chamber 12 is formed between the cover panel 3 and the front end of the adhesive anchor 1 which is set back by the protruding support edge 10, with the area of the chamber corresponding to virtually the entire area of the adhesive anchor 1.
Said chamber 12 can now be filled completely with an adhesive, glue or the like, so that every adhesive anchor 1 is glued together with the cover panel 3 over its entire surface area.
Furthermore, every adhesive anchor 1 is provided at its end opposite of the support edge 10 with a circumferential collar 13 which rests at least partly flush within the bore 9. An adhesive, glue or the like is also used in the region of this mutual contact in order to securely fix the adhesive anchor 1 within the bore 9.
The features as described above are provided in all illustrated embodiments, so that only the special design features of the different embodiments will be explained below in closer detail.
Notice must be taken with respect to Figs. 1 to 7 that the adhesive anchor 1 illustrated there can also be fixed to the trimming strips 14 of a lightweight building panel 2 which is used as a table top. For this purpose, the adhesive anchor 1 is equipped with grooves 15 which are preferably arranged to be offset at an angle of 90 with respect to one another according to the mentioned Figs. 1 to 7, which grooves offer the possibility in the support region of the adhesive anchor 1 in relation to the trimming strips 14 to anchor the adhesive anchor 1 in addition in relation to the trimming strips 14 by adhesive or glue or the like introduced into these grooves 15. This is shown especially in the illustration according to Fig. 1.
Moreover, the adhesive anchor 1 according to the Figs. I to 7 consists of a sleeve-like component 16 and a plug-in peg 17 that can be introduced into said component 16. As is shown especially in the perspective illustration according to Fig. 4, the plug-in peg 17 is equipped at one end with a cover 18 whose area corresponds to the area of the sleeve-like component 16. After the introduction of the plug-in peg 17 into component 16, the cover forms the upper end of the two-part adhesive anchor 1.
The plug-in peg 17 comprises the mentioned screw-in channel 6 for a fastening screw 7.
The plug-in peg 17 is provided on the outside with longitudinal grooves 19 which extend in the direction of the longitudinal axis of the plug-in peg 17, of which several longitudinal grooves 19, but at least two thereof, are distributed over the circumference of the plug-in peg 17. The elevated sections of the plug-in peg 17 which delimit the longitudinal grooves 19 rest in a virtually sealing manner on the walls of an insertion opening 20 of the sleeve-like component 16. The longitudinal grooves 19 extend in the axial direction up to the region of the bottom face 11 of the sleeve-like component 16 and extend on the other hand up to the upper side of the component 16 and converge there into radially extending outlet openings which are disposed in the region of the collar 13.
The screw-in channel 6 of the plug-in peg 17 is sealed in the axial direction in its bottom end disposed away from the cover 18. In this bottom region, there are two lateral, radially extending filling openings 21 which each open into a longitudinal groove 19 of the plug-in peg 17.
As a result of the described construction, the transport of a fluid adhesive or glue to all relevant and desired points is not easily possible. A suitable tool is immersed to such an extent into the screw-in channel 6 that this tool lies with its bottom end in the region of the filling openings 21 of the plug-in peg 17. This tool is used to convey fluid adhesive, glue or the like via the filling openings into the region of the longitudinal grooves 19. These longitudinal grooves 19 form flow channels with the respectively opposite wall regions of the insertion opening 20, which flow channels open at the bottom side into the region of the chamber 12 disposed there and at the upper side into radially extending outlet openings, so that the fluid adhesive, glue or the like can be introduced into the region of the chamber 12 as reliably as into the opposite upper region of collar 13 which is disposed within the bore 9.
Since the grooves 15 further extend up to the region of the chamber 12 in the jacket region of the sleeve-like component, these grooves 15 are also filled in a rising manner with adhesive or glue, so that a reliable gluing of the adhesive anchor 1 can be made within the non-drilled cover panel 3, the trimming strips 14 and the bore 9 of the upper cover panel 4.
This ensures optimal fixing of the adhesive anchor in relation to the lightweight building panel 2. The upper region of the screw-in channel 6 which is used for twisting in the fastening screw 7 is completely free of glue and is dimensioned in its entirety in such a way that a fastening screw 7 will tightly anchor in this screw-in channel 6 in the manner of a self-cutting screw.
The adhesive anchor 1 is made in its entirety of plastic, which means both the sleeve-like component 16 and the plug-in peg 17 with its cover 18 are made of a suitable plastic.
As a result of this construction and fixing of the adhesive anchor 1, a table-leg 8 can be connected in a fixed and compensating manner to the lightweight building panel despite the use of an inexpensive lightweight building panel 2.
As is shown especially clearly in Figs. 6 and 7, the outlet openings 22 which have already been mentioned above and extend radially to the outside are disposed between the upper side of the sleeve-like component 16 and the bottom side of the cover 18 of the plug-in peg 17, so that any adhesive, glue or the like that reaches there can not only reach the region of the collar 13 disposed within the bore 9 but can also glue and connect the cover 18 with the sleeve-like component 16.
The adhesive anchor 1 according to Figs. 8 to 12 differs from the adhesive anchor 1 according to the aforementioned embodiment according to Figs. I to 7 by a smaller diameter on the one hand, and by the fact on the other hand that no grooves 15 are provided in the circumferential region of the sleeve-like component 16 and especially by the fact that the screw-in channel 6 extends offset from the center in relation to the longitudinal axis of the adhesive anchor 1.
In all other respects, the configuration of the adhesive anchor 1 according to the Figs. 8 to 12 functionally corresponds to the aforementioned embodiment, i.e. in this case too flow channels are formed by the arrangement of the plug-in peg 17 with its longitudinal grooves 19, by means of which adhesive, glue or the like can be introduced securely into the bottom region of the adhesive anchor 1 which rests on a cover panel and into an upper region of the adhesive anchor 1 which rests in the region of the bore 6 of the other cover panel 4, so that an optimal connection is ensured between the adhesive anchor 1 and the respective contact regions of said adhesive anchor 1 in relation to a lightweight building panel 2.
As is shown especially clearly in Figs. 11b and 1 ld, the sleeve-like component 16 is provided on the bottom side again with an axially protruding support edge 10, so that the respective front end 11 of this component 16 is set back in relation to the contact plane of the support edge 10. A chamber is thus formed again by the front end 11, the support edge 10 and the area of the cover plate 3 on which the support edge 10 rests, to which adhesive or glue can be supplied for gluing the adhesive anchor 1 over the entire surface area in the contact region to the non-drilled cover panel 3. As a result of the analogously formed flow channels, the upper region of the adhesive anchor 1 which forms a collar 13 is securely glued in the bore 9.
Furthermore, the cover 18 of the plug-in peg 17 is tightly connected with the sleeve-like component 16 by gluing, sizing or the like.
An adhesive anchor 1 is also realized in the embodiment according to the Figs.
13 to 16, which anchor is formed in two parts and made of a sleeve-like component 16 and a plug-in peg 17. The insertion opening 20 for the plug-in peg 17 is arranged centrally again and flow channels are formed again by the longitudinal grooves 19 of the plug-in peg 17 in the above described manner in conjunction with the walls of the insertion opening 20, which flow channels extend from the bottom side of the adhesive anchor 1 to the upper region and open there into radial outlet openings 22.
An adhesive anchor which is arranged in a comparatively simple way according to Figs. 13 to 16 and also has a relatively small diameter will preferably be used when components are to be connected to a lightweight building panel which is not subjected to extremely high loads.
Figs. 17 to 30 show an adhesive anchor 1 in a single-piece configuration. It can be seen that this single-piece configuration comprises a separate filling bore 23 for an adhesive or glue in addition to the screw-in channel 6 for accommodating a fastening screw 7. Said filling bore 23 extends through the entire adhesive anchor I and opens on the bottom side into the chamber 12 which is delimited by the axially protruding support edge 10, the non-drilled cover panel 3 and the front end 11 of the adhesive anchor 1 which is not set back in relation to the support edge 10. Glue can be introduced into said chamber 12 from the upper side of the adhesive anchor 1. Starting from this chamber 12, rising bores 24 which form flow channels extend to the upper side of the adhesive anchor 1 up to the region of the radial outlet openings 22 which are disposed in the region of an upper circumferential collar 13 which is disposed in the bore 9 of the drilled-through cover panel 4 in the mounted state of the adhesive anchor 1.
In this construction, the guidance for the adhesive or glue occurs in the manner that the adhesive or glue pressed at first through the filling opening 23 into the region of the bottom front end 11 of the adhesive anchor, is pressed upwardly from there via the risers 24 and into the region of the collar 13 via the radially extending outlet openings 22 and thus into the perforated wall region of bore 9 of the drilled-through cover panel 4.
It is therefore also ensured in this single-piece embodiment that the adhesive anchor 1 is glued together over its entire area with a non-drilled cover panel 3 and additionally in the perforated wall region of the bore 9 of the drilled-through cover panel 4.
Notice shall be taken by reference to Fig. 25 that guide ribs 25 are provided in the region of the bottom end of adhesive anchor 1 which is covered by the support edge 10, which guide ribs ensure an even distribution of the glue or an adhesive over the area of the adhesive anchor 1.
Comparable guide ribs 25 in other geometrical arrangements can also be provided in the adhesive anchors 1 according to the embodiments as described above.
There is the possibility in the two-piece arrangements to provide the cover 18 of the plug-in peg 17 at least in sections with such a thin configuration that a certain transparency is achieved, so that it is clearly recognizable to the fitter when the filled-in adhesive or glue has reached up to the region of the radial outlet openings 22. The further supply with adhesive or glue can then be stopped immediately and the undesirable leakage of adhesive or glue can be prevented.

The drawings show a total of four different embodiments of adhesive anchors in accordance with the invention, with these adhesive anchors being provided consistently with reference numeral 1.
Figs. 1 to 7, 8 to 12 and 13 to 16 each show a two-part adhesive anchor 1, whereas the embodiment according to Figs. 17 to 30 shows a one-piece adhesive anchor 1.
Such an adhesive anchor I is generally determined for being inserted into a lightweight building panel which is designated in its entirety with reference numeral 2.
The lightweight building panel 2 consists in the known manner of a first and second cover panel 3, 4 and an interposed center layer 5 which has a honeycomb structure in the known manner. For reasons of clarity, the more detailed view of this honeycomb structure in the region of the center layer 5 has been omitted.
The two cover panels 3 and 4 are preferably made of wood or a wood-like material.
Every adhesive anchor 1 is provided with a screw-in channel 6 which is used for accommodating a fastening screw 7, by means of which a table-leg 8 shall be fastened for example to a lightweight building panel 2 which is used as a table top.
In order to ensure secure fixing of the table-leg 8 which can be subjected both to high static and dynamic loads, it is very important that an adhesive anchor 1 can be fixed in a very secure manner within the lightweight building panel 2.
In order to achieve this goal, it is provided in all adhesive anchors 1 which are inserted through a bore 9 in one of the cover panels 4 into the lightweight building panel 2 and rest on the inside of the other cover panel 3 opposite of the bore 9 that the front end resting on the cover panel 3 comprises a support edge 10 protruding in the direction of the longitudinal axis of the adhesive anchor 1, so that a chamber 12 is formed between the cover panel 3 and the front end of the adhesive anchor 1 which is set back by the protruding support edge 10, with the area of the chamber corresponding to virtually the entire area of the adhesive anchor 1.
Said chamber 12 can now be filled completely with an adhesive, glue or the like, so that every adhesive anchor 1 is glued together with the cover panel 3 over its entire surface area.
Furthermore, every adhesive anchor 1 is provided at its end opposite of the support edge 10 with a circumferential collar 13 which rests at least partly flush within the bore 9. An adhesive, glue or the like is also used in the region of this mutual contact in order to securely fix the adhesive anchor 1 within the bore 9.
The features as described above are provided in all illustrated embodiments, so that only the special design features of the different embodiments will be explained below in closer detail.
Notice must be taken with respect to Figs. 1 to 7 that the adhesive anchor 1 illustrated there can also be fixed to the trimming strips 14 of a lightweight building panel 2 which is used as a table top. For this purpose, the adhesive anchor 1 is equipped with grooves 15 which are preferably arranged to be offset at an angle of 90 with respect to one another according to the mentioned Figs. 1 to 7, which grooves offer the possibility in the support region of the adhesive anchor 1 in relation to the trimming strips 14 to anchor the adhesive anchor 1 in addition in relation to the trimming strips 14 by adhesive or glue or the like introduced into these grooves 15. This is shown especially in the illustration according to Fig. 1.
Moreover, the adhesive anchor 1 according to the Figs. I to 7 consists of a sleeve-like component 16 and a plug-in peg 17 that can be introduced into said component 16. As is shown especially in the perspective illustration according to Fig. 4, the plug-in peg 17 is equipped at one end with a cover 18 whose area corresponds to the area of the sleeve-like component 16. After the introduction of the plug-in peg 17 into component 16, the cover forms the upper end of the two-part adhesive anchor 1.
The plug-in peg 17 comprises the mentioned screw-in channel 6 for a fastening screw 7.
The plug-in peg 17 is provided on the outside with longitudinal grooves 19 which extend in the direction of the longitudinal axis of the plug-in peg 17, of which several longitudinal grooves 19, but at least two thereof, are distributed over the circumference of the plug-in peg 17. The elevated sections of the plug-in peg 17 which delimit the longitudinal grooves 19 rest in a virtually sealing manner on the walls of an insertion opening 20 of the sleeve-like component 16. The longitudinal grooves 19 extend in the axial direction up to the region of the bottom face 11 of the sleeve-like component 16 and extend on the other hand up to the upper side of the component 16 and converge there into radially extending outlet openings which are disposed in the region of the collar 13.
The screw-in channel 6 of the plug-in peg 17 is sealed in the axial direction in its bottom end disposed away from the cover 18. In this bottom region, there are two lateral, radially extending filling openings 21 which each open into a longitudinal groove 19 of the plug-in peg 17.
As a result of the described construction, the transport of a fluid adhesive or glue to all relevant and desired points is not easily possible. A suitable tool is immersed to such an extent into the screw-in channel 6 that this tool lies with its bottom end in the region of the filling openings 21 of the plug-in peg 17. This tool is used to convey fluid adhesive, glue or the like via the filling openings into the region of the longitudinal grooves 19. These longitudinal grooves 19 form flow channels with the respectively opposite wall regions of the insertion opening 20, which flow channels open at the bottom side into the region of the chamber 12 disposed there and at the upper side into radially extending outlet openings, so that the fluid adhesive, glue or the like can be introduced into the region of the chamber 12 as reliably as into the opposite upper region of collar 13 which is disposed within the bore 9.
Since the grooves 15 further extend up to the region of the chamber 12 in the jacket region of the sleeve-like component, these grooves 15 are also filled in a rising manner with adhesive or glue, so that a reliable gluing of the adhesive anchor 1 can be made within the non-drilled cover panel 3, the trimming strips 14 and the bore 9 of the upper cover panel 4.
This ensures optimal fixing of the adhesive anchor in relation to the lightweight building panel 2. The upper region of the screw-in channel 6 which is used for twisting in the fastening screw 7 is completely free of glue and is dimensioned in its entirety in such a way that a fastening screw 7 will tightly anchor in this screw-in channel 6 in the manner of a self-cutting screw.
The adhesive anchor 1 is made in its entirety of plastic, which means both the sleeve-like component 16 and the plug-in peg 17 with its cover 18 are made of a suitable plastic.
As a result of this construction and fixing of the adhesive anchor 1, a table-leg 8 can be connected in a fixed and compensating manner to the lightweight building panel despite the use of an inexpensive lightweight building panel 2.
As is shown especially clearly in Figs. 6 and 7, the outlet openings 22 which have already been mentioned above and extend radially to the outside are disposed between the upper side of the sleeve-like component 16 and the bottom side of the cover 18 of the plug-in peg 17, so that any adhesive, glue or the like that reaches there can not only reach the region of the collar 13 disposed within the bore 9 but can also glue and connect the cover 18 with the sleeve-like component 16.
The adhesive anchor 1 according to Figs. 8 to 12 differs from the adhesive anchor 1 according to the aforementioned embodiment according to Figs. I to 7 by a smaller diameter on the one hand, and by the fact on the other hand that no grooves 15 are provided in the circumferential region of the sleeve-like component 16 and especially by the fact that the screw-in channel 6 extends offset from the center in relation to the longitudinal axis of the adhesive anchor 1.
In all other respects, the configuration of the adhesive anchor 1 according to the Figs. 8 to 12 functionally corresponds to the aforementioned embodiment, i.e. in this case too flow channels are formed by the arrangement of the plug-in peg 17 with its longitudinal grooves 19, by means of which adhesive, glue or the like can be introduced securely into the bottom region of the adhesive anchor 1 which rests on a cover panel and into an upper region of the adhesive anchor 1 which rests in the region of the bore 6 of the other cover panel 4, so that an optimal connection is ensured between the adhesive anchor 1 and the respective contact regions of said adhesive anchor 1 in relation to a lightweight building panel 2.
As is shown especially clearly in Figs. 11b and 1 ld, the sleeve-like component 16 is provided on the bottom side again with an axially protruding support edge 10, so that the respective front end 11 of this component 16 is set back in relation to the contact plane of the support edge 10. A chamber is thus formed again by the front end 11, the support edge 10 and the area of the cover plate 3 on which the support edge 10 rests, to which adhesive or glue can be supplied for gluing the adhesive anchor 1 over the entire surface area in the contact region to the non-drilled cover panel 3. As a result of the analogously formed flow channels, the upper region of the adhesive anchor 1 which forms a collar 13 is securely glued in the bore 9.
Furthermore, the cover 18 of the plug-in peg 17 is tightly connected with the sleeve-like component 16 by gluing, sizing or the like.
An adhesive anchor 1 is also realized in the embodiment according to the Figs.
13 to 16, which anchor is formed in two parts and made of a sleeve-like component 16 and a plug-in peg 17. The insertion opening 20 for the plug-in peg 17 is arranged centrally again and flow channels are formed again by the longitudinal grooves 19 of the plug-in peg 17 in the above described manner in conjunction with the walls of the insertion opening 20, which flow channels extend from the bottom side of the adhesive anchor 1 to the upper region and open there into radial outlet openings 22.
An adhesive anchor which is arranged in a comparatively simple way according to Figs. 13 to 16 and also has a relatively small diameter will preferably be used when components are to be connected to a lightweight building panel which is not subjected to extremely high loads.
Figs. 17 to 30 show an adhesive anchor 1 in a single-piece configuration. It can be seen that this single-piece configuration comprises a separate filling bore 23 for an adhesive or glue in addition to the screw-in channel 6 for accommodating a fastening screw 7. Said filling bore 23 extends through the entire adhesive anchor I and opens on the bottom side into the chamber 12 which is delimited by the axially protruding support edge 10, the non-drilled cover panel 3 and the front end 11 of the adhesive anchor 1 which is not set back in relation to the support edge 10. Glue can be introduced into said chamber 12 from the upper side of the adhesive anchor 1. Starting from this chamber 12, rising bores 24 which form flow channels extend to the upper side of the adhesive anchor 1 up to the region of the radial outlet openings 22 which are disposed in the region of an upper circumferential collar 13 which is disposed in the bore 9 of the drilled-through cover panel 4 in the mounted state of the adhesive anchor 1.
In this construction, the guidance for the adhesive or glue occurs in the manner that the adhesive or glue pressed at first through the filling opening 23 into the region of the bottom front end 11 of the adhesive anchor, is pressed upwardly from there via the risers 24 and into the region of the collar 13 via the radially extending outlet openings 22 and thus into the perforated wall region of bore 9 of the drilled-through cover panel 4.
It is therefore also ensured in this single-piece embodiment that the adhesive anchor 1 is glued together over its entire area with a non-drilled cover panel 3 and additionally in the perforated wall region of the bore 9 of the drilled-through cover panel 4.
Notice shall be taken by reference to Fig. 25 that guide ribs 25 are provided in the region of the bottom end of adhesive anchor 1 which is covered by the support edge 10, which guide ribs ensure an even distribution of the glue or an adhesive over the area of the adhesive anchor 1.
Comparable guide ribs 25 in other geometrical arrangements can also be provided in the adhesive anchors 1 according to the embodiments as described above.
There is the possibility in the two-piece arrangements to provide the cover 18 of the plug-in peg 17 at least in sections with such a thin configuration that a certain transparency is achieved, so that it is clearly recognizable to the fitter when the filled-in adhesive or glue has reached up to the region of the radial outlet openings 22. The further supply with adhesive or glue can then be stopped immediately and the undesirable leakage of adhesive or glue can be prevented.
