Description

The The invention relates to an arrangement for attaching a baseboard on a wall with the features in the preamble of claim 1 and a Drilling template with the features in the preamble of claim 13.

baseboards form a clean finish in the transition area between floor and wall, because here usually collide different materials, the usually visually unsightly Forming a column. It is known skirting boards made of wood, wooden materials or nail plastic, but the nail head visible remains. Also hidden holder for attaching the baseboard are known. In general, these holders are e.g. through nails at the Wall to attach. It is also known to screw such holders. Both the nailing of the holder and the screwing is not unproblematic, since the installation is done with special care got to. Otherwise it can not be guaranteed that the baseboard evenly worn by all owners will and that the baseboard exactly the desired Course has.

From the DE 1 509 675 A1 is an arrangement for fixing a skirting board or the like on a wall with an inserted into a borehole in the wall expansible plug known, in which a pin-like spreading member is driven. The expansion anchor is formed integrally with the connecting element. The assembly of the connecting element on the wall is due to the relatively small-sized spreading member as cumbersome as the hammering of a nail. In addition, drill holes must be set. The material of the wall must have sufficient strength so that the spreading forces can be absorbed.

From the DE 299 14 856 U1 a skirting board system for covering heating pipes or the like is known, consisting of profile elements which are mounted at a distance and aligned with each other on a wall and record heating pipes and / or the like supply strands in their insertion channels. On the mounting profile elements a cover strip can be placed. The mounting profile elements consist of a thermoplastic material. An integrally formed plug-in pin is peripherally provided with anchor plates which hold the mounting profile elements in the borehole.

The DE 19 30 182 U discloses a plastic baseboard. The baseboard is connectable with anchored in the wall fasteners by tongue and groove snap engagement, so that the baseboard can also be subsequently removed from the wall while the fastener remains in the wall. The fastener is screws, dowels or the like, whose head is provided with a profile for a snap connection.

A foot or rubbing strip is the subject of DE 18 59 378 U , wherein the baseboard is plugged from above onto a fastener. In the fastener, a cable channel is formed according to the JP 2005 139 739 AA may be provided in the mouth area with resilient tongues, so that the introduced into the cable duct cables or lines can not automatically slip out of the cable channel.

With the DE 19 88 773 U a device for attaching holders for skirting has become known. It is envisaged that first a nail is inserted into a head of a firing pin device such that the nail extends with its tip through an opening in the holder and that subsequently with the firing pin of the nail is driven with the holder in the wall, so that only one blow is required to secure the bracket to the wall with the nail.

Finally, that is still DE 19 50 364 U to the prior art, which relates to a protective, ornamental or support strip for the interior of rooms with detachable fastening device, wherein the strip is preferably made of impact-resistant plastic and on the back by means of spacer webs a cavity is formed, wherein in the region of the back a clip web is formed with a substantially C-shaped groove which can be plugged onto a crowned head of a wall-mounted anchor.

Of these, Based on the object of the invention, an arrangement for attaching a baseboard on a wall with one inserted into a borehole in the wall Holder made of plastic and a foot strip attachable to the holder show, with the holder very easy and quick to install is. Furthermore, an improved drilling template specifically for this Holder can be shown.

The The first object is in the arrangement with the features of the claim 1 solved. The drilling template is the subject of claim 13.

It is essential that the holder has a fastening foot engaging in the borehole, which has a plurality of disk-shaped, spaced apart in the longitudinal direction of the mounting foot in spaced armature lamellae whose diameter is dimensioned such that the anchor blades dig into the wall of the borehole automatically. Through the anchor blades, the holder can be inserted as far as possible by hand into the hole. Then the holder can be driven with a few hammer blows. Other tools and in particular other components are not required for insertion of the holder. The mounting foot does not spread within the wall, but is configured so that it can not easily be removed from the wellbore. For this purpose, a plurality of anchor plates are provided, which are dimensioned so thin in their wall thickness that they are limited flexibility. When driving the mounting foot, the anchor plates are thus circumferentially on the wall of the borehole and digs there automatically. The diameter of the lamellae is exactly matched to the diameter of the borehole, with the lamellae deforming slightly against the direction of insertion when driven into the borehole. If the holder is now to be removed from the wall again, the deformation of the anchor plates must first be overcome. That is, the anchor plates must be deformed in the opposite direction, which requires a considerable amount of force. Consequently, the holder is very safe and firmly fixed in the wellbore.

The free end of the anchor foot is with an enlarged diameter in diameter relative to the core end portion Mistake. The diameter of the end section is smaller as the diameter of the anchor blades. The end section slides possibly existing cuttings into the well, so that the anchor blades not on the cuttings, but directly to supported the wall of the borehole are. Furthermore, the enlarged end section the advantage that it is used as an injection point for injection-molded Holder can serve. The thin-walled Slats are suitable in this regard not because they do not have the required thickness. Furthermore protects the enlarged diameter end portion from injuries of the rest pointed core.

advantageous Embodiments of the inventive concept are the subject of the dependent claims.

In a first embodiment it is envisaged that the mounting foot a bearing the anchor plates Has core that tapers towards the free end of the mounting foot. At the same remaining diameter of the anchor blades means that the the free end adjacent anchor plates are easier to deform as the anchoring lamellae farther away from the free end. By varying the diameter of the core and varying the wall thickness The lamellae, the pull-out safety of the holder within wide limits to be influenced. Of course plays Also, the material from which the holder is made, a crucial Role. Important is an easy and fast mountability at the same time high pull-out safety.

Of the The core itself, like the anchor blades, can be configured circular in cross-section be. It is regarded as advantageous, however, if the core in Cross-section star-shaped or configured in a cross shape is. This can increase cuttings and abrasion from the walls of the borehole between the slats are received. At the same time Material saved and the component is lighter overall.

The Anchor plates can basically about the whole length of the mounting foot extend. However, it is considered advantageous if the mounting foot a Ankerlamellenfreien center section has. The middle section represents in principle, an extension of the core, which is no longer in the middle section tapered, but has a constant cross-section. The star- or cross-shaped cross-sectional configuration can continue in the middle section be. In addition, at least a radial at this central portion be arranged above fixing lug, which inter alia as anti-rotation of the mounting foot within the borehole. The fixing nose is preferably on the Arranged top of the center section. That has the advantage, that the middle section over the fixing nose primary supported at the top of the borehole. This will be the middle section pushed down in the installation position, so that the holder too at a slight angle introduced boreholes pressed down a bit is and in the optimal case is vertical.

In a further embodiment closes at the mounting foot a support portion which is an extension of the middle section. The support section connects one upwardly directed support bar with a parallel distance extending to the support bar stop leg of a support section. The support strip engages during assembly in a Einstecknut the baseboard. For this purpose, the holders are at a distance of 40 cm to 50 cm mounted on the wall. Subsequently can the baseboard be put on the support bar from above. The distance of the support bar across from the wall is defined by the stop leg, which when driving the Holder in the wall serves as a stop.

The stop leg is part of a support section. The bearing section is U-för mig configured and includes a relative to the stop leg angled Auflagsteg for resting on the floor and a subsequent to the Auflagersteg front leg. The stop leg and the front leg preferably run parallel to each other, while the support web extends horizontally and thus rests flat on the ground. The U-shaped support section serves as a cable channel. For this purpose, the support bar at its lower end portion have at least one directed towards the upper end of the front leg spring tongue or the upper end of the front leg has at least one directed towards the lower end portion of the support bar spring tongue. Preferably, the spring tongues towards each other. The spring tongues are designed so flexible that a cable can be clipped by the mouth formed by the spring tongues in the U-shaped configured support section. The spring tongues prevent the cable from slipping out of the support section during assembly.

Basically it considered sufficient, if the holder only one by Spring tongues has limited bottleneck. Therefore, the lower End portion of the support bar in the form of a standing on top Triangle configured, where at the top of the triangle Spring tongue can be arranged. As a result, the holder is also total lighter because less material is required.

When Another feature of the arrangement according to the invention, the upper End section of the support bar have chamfers in its corner regions, which are configured as flats of the upper end section. The upper end portion of the support bar preferably has a central area, which is about over one third of the total length of the End section extends while the respective peripheral third are executed flattened. That way you can Canting of the holder can be compensated so that the corner areas no over projecting the central area upwards, even if the upper edge of the support section is not completely horizontal.

Should the holder e.g. not due to different wall materials can be pinned so optionally provide screw holes in the stop leg the possibility of the Holder on conventional Way screw technology to fix. Preferably, the screw holes as an end, U-shaped Configured notches configured in the stop leg. to Attachment can for example, commercial dowels, e.g. the size 6, and appropriate screws are used. To insert the screws To simplify, the upstream front leg can at its upper End in the corner area chamfers, which correspond to the position of screw holes are adjusted.

When it is considered particularly advantageous if the assembly means a drilling template according to the features of claim 13 takes place. The drilling template comprises a vertical leg, which has bores corresponding to the drilling pattern of the holder and a horizontal leg connected to the vertical leg to rest on the ground. Important here is that the horizontal leg designed to protect the soil so long and wide that a drill head a hand drill is not in contact with the ground when drilling arrives. Since the holders must be mounted extremely close to the ground, there is a special risk, a freshly laid flooring by the Inserting the drill holes to damage. The drilling template according to the invention is a crucial help in the assembly, because through their Use the mounting of the baseboard further simplify. With the drilling template can the holes Naturally even be marked without being bored by the holes in the Drilling template is drilled.

The Surgical template is preferably made of plastic, in particular Made of a highly elastic plastic, which also with impact load does not splinter or break with a hammer. A wall thickness of 2 mm to 3 mm is considered sufficient to protect the soil to serve. A wall thickness thickening is in the field of holes in the vertical leg appropriate because the drilling template at a large Number of holes may be worn and the holes inaccurate could become. A wall thickness thickening may be provided in particular in the peripheral region of the holes. It is preferably sharp-edged and assigned to the wall Page arranged. In this configuration, the wall thickness thickening by hammer blows on the vertical leg like a grain an impression in the wall leave a mark indicating the position of the borehole. Even if the drill pattern should be worn after multiple use, The drilling template can still be used as soil protection when setting the holes serve.

For an exact alignment of the horizontal leg relative to the vertical leg is provided that they are connected to each other via at least one angle brace. The angle struts are preferably arranged in the corner region. In addition, the horizontal leg can be provided with at least one side grip tab for ease of handling. So that the grip tab does not interfere with drilling, this can lie in the horizontal plane of the horizontal leg. He There is an overall substantially L-shaped configuration with a shorter vertical leg and a much longer horizontal leg. The horizontal leg can have a length of about 8 cm to 15 cm and a width between 6 cm and 10 cm. Depending on the drilling pattern, a height of the horizontal leg of 2 cm to 4 cm is considered sufficient.

1 shows a baseboard 1 pointing in the direction of the arrow P to a holder 2 is plugged. The holder 2 is a plastic component that is to be inserted in a manner not shown in a borehole in a wall. The holder 2 is through a mounting foot 3 anchored in the borehole, not shown. This is the mounting foot 3 first driven by hand and finally with light hammer blows in the hole. Here are the mutually spaced anchor plates 4 on the wall of the borehole. The anchor blades 4 are configured disk-shaped and are on a core 5 attached. The core 5 of the mounting foot 3 tapers towards the free end 6 of the mounting foot. The free-carrying length of the anchor plates 4 in return takes the free end 6 of the mounting foot 3 towards, while the diameter of the anchor plate is constant. The free end 6 of the mounting foot 3 has a diameter opposite the core 5 enlarged end section 7 on, whose diameter D1 is smaller than the diameter D2 of the armature blades 4 , All anchor blades 4 have the same diameter D2. The anchor blades 4 are on their end section 7 facing side circumferentially with a chamfer 8th provided so that is on the free end 6 opposite side a sharp circumferential edge 9 shows, through which the anchor blades 4 self-locking in the wall of the borehole.

The core 5 is cross-shaped in cross section. This is done by four circumferential and longitudinally of the mounting foot 3 extending notches 10 guaranteed. The diameter of the core 5 is in any case smaller than the diameter D2 of the anchor plates 4 ,

At the anchor blades 4 carrying length section of the mounting foot 3 closes a anchor lamella-free middle section 11 which is about half as long as the anchor blades 4 carrying length section. At this middle section 11 there is a fixing nose 12 which is configured wedge-shaped and towards the free end 6 of the mounting foot 3 rejuvenated. The fixing nose 12 extends on the top of the middle section 11 radially outward over the diameter D2 of the anchor plates 4 out.

To the middle section 11 closes a support section 13 at. The supporting section 13 is cylindrical and corresponds in its outer diameter to the diameter of the central portion 11 , The supporting section 13 , the middle section 11 as well as the core 5 with the end section 7 lie on a common central longitudinal axis, so that one can speak of a pen-shaped configuration as a whole. The supporting section 13 connects one from the support section 13 starting upwards support bar 14 that fit into an insertion groove 15 the baseboard 1 intervenes. From the cylindrical support section 13 downwards extends in parallel distance to the support bar 14 a stop leg 16 a support section 17 , The support section 17 is configured U-shaped and further includes a horizontally extending Auflagersteg 18 to rest on the floor and one to the Auflagersteg 18 at right angles adjoining front leg 19 , In this support section 17 is a cable 20 recorded, like out 1 is recognizable. The front leg 19 serves to support the lower end 21 the baseboard 1 , How out 2 it recognizes the footer 1 on the high slide by three in the longitudinal direction of the support bar 4 extending locking strips 22 prevented. Through these locking strips 22 is the baseboard 1 on the support bar 14 clamp mounted.

Based on 2 to 5 Below is the detailed structure of the holder 2 described in more detail. The support bar 14 has a lower end portion 23 on, which is configured in the form of a triangle standing on the top. The tip of this triangle is a pliable spring tongue 24 provided on another spring tongue 25 at the top 26 of the front leg 29 is directed. Out 1 it can be seen that the spring tongues 24 . 25 facing each other and forming a mouth through which the cable 20 in the support section 17 can be clipped. By the spring tongues 24 . 25 is the cable 20 in the support section 17 kept captive.

Above the spring tongue 24 is in extension of the support section 13 of the mounting foot 3 a frustoconical pedestal 27 as a marker for knocking in the holder 2 into the borehole. The height of the pedestal 27 is sized so that he has the locking bars 22 protruding so that they can not be damaged during assembly.

The support bar 14 has at its upper end portion 28 each in the corner chamfers 29 totaling about two-thirds of the total width B of the support bar 14 extend. Such chamfers 30 can also be found at the top 26 of the front leg 19 , Out 5 it becomes clear that the chamfers 30 in the front leg 19 to the position of screw holes 31 are adapted to the end U-shaped configured notches in the stop leg 16 are formed. 3 lets recognize that the fixing nose 12 Overall wedge-shaped is configured and moving towards the free end 6 not only in height, but also in width tapers.

Furthermore, it can be seen that all notches 10 are equally configured, so that - apart from the fixing nose 12 - Overall, a rotationally symmetrical cross section results.

The 6 to 9 show a drilling template 32 which is part of the arrangement according to the invention. The drilling template 32 is a plastic component and has a vertical leg 33 and a right angle thereto arranged horizontal leg 34 on. The vertical leg 33 has three holes 35 . 36 on, the drill pattern of the holder 2 of the 1 correspond. The horizontal leg 34 is designed to be much larger in length as well as in width than the vertical leg 33 , It serves to protect the soil in front of the rotating drill head of a hand drill when drilling through the holes 35 . 36 , For improved handling of the vertical leg 33 over angle struts 37 opposite the horizontal leg 34 stiffened. In addition, the horizontal leg has 34 alongside each side handle grips 38 on, located in the horizontal plane of the horizontal leg 34 are located. The grip bottles are profiled. The wall thickness of the vertical leg 33 is in the area of the hole 35 elevated.

This is based on the cone-shaped extension 39 in the 7 and 9 to recognize.
