Description

The invention relates to a device for fastening posts on a hard surface, containing an anchor element with fasteners for Fixation to the surface and one detachable with the anchor element connectable post support for receiving a post end.

Fastening devices of the type mentioned are, for example needed when the post of an umbrella, a clothesline, one Information sign, a fence or the like on a concrete, tarred, paved or tiled surface to be erected. For this purpose Known devices have a tubular post support Insert the post end, which is permanently with the underground is screwed. The disadvantage of this, however, is that the post support as disturbing obstacle e.g. remains on a terrace if no post is used.

Furthermore, DE 34 01 015 A1 is a two-part fastening device known in which an anchor element designed as a bolt in the underground is concreted in and a post support with upward-facing tabs on the the thread of the anchor element protruding from the base is screwed on can be. The post carrier could be relatively easy if necessary Anchor element to be unscrewed again, but then that would be up standing threads of the anchor element form a dangerous trip hazard.

Furthermore, DE 199 08 265 A1 is a two-part fastening device known for the gable wall support of a tent or a hall. Here is a plate-shaped anchor element anchored to the ground with pegs. Up Bolts protruding from the anchor element can have holes in the plate-shaped base protrude through an attached gable wall support, this connector can be secured by spring elements or the like. This one too Fastening device would therefore be in the disassembled state Fixing bolts remain as tripping hazards.

From JP 6-57900 A an assembly device for railings is known from which is first screwed an anchor element onto the surface which can then be attached to a post support by screws. The Anchor elements have a cylindrically curved top, which in Is provided with ribs in the direction of the cylinder axis. The complementary to this Shaped bottom of the post bracket can therefore be gradual in different Angular positions, each by mutual engagement of the ribs are specified to be put on.

US 1 552 569 relates to a fastening mechanism for the posts of a Banister on a staircase. Here are anchor elements in the cement Stairs embedded, on which then further device parts can be screwed tight. Devices with those to be embedded in the underground Anchor elements are further shown in US 3,328,057 and US 1,725,507.

From JP 2001-349031 A is a fastening device for railing posts known on a straw mat (tatami). In a special embodiment (Figure 4) is an anchor element with a bead-shaped edge and an in the middle of the raised collar to hold a post on the straw mat nailed. To hide the nail heads, the anchor element is covered by a plate-shaped hood covered.

Against this background, it was an object of the present invention, a Device for attaching posts to a hard surface such as to provide a terrace, which on the one hand is simple and can also be added later is to be attached and on the other hand a conversion into a non-use state should allow in which it disturbs as little as possible.

This object is achieved by a device with the features of claim 1 solved. Advantageous refinements are contained in the subclaims.

• Ein Ankerelement mit Befestigungsmitteln, vermöge der es an bzw. auf dem Untergrund fixiert werden kann. Der Untergrund muss dabei nicht unbedingt eine horizontale Bodenfläche sein, sondern kann ebenso eine vertikale, schräge oder überhängende Wand- oder Deckenfläche sein.
• Einen Pfostenträger zur Aufnahme eines Pfostenendes, welcher mit dem Ankerelement so verbindbar ist, dass er verhältnismäßig leicht und vorzugsweise ohne Werkzeug wieder hiervon gelöst werden kann. Der Pfostenträger kann ansonsten in jeder geeigneten Weise zur Aufnahme des Pfostenendes ausgebildet sein. Insbesondere kann er eine Hülse aufweisen, in welche das Pfostenende eingesteckt werden kann.

The device according to the invention for fastening posts on a hard surface, such as a terrace floor, has two main components, namely:

• An anchor element with fasteners, by which it can be fixed on or on the ground. The surface does not necessarily have to be a horizontal floor surface, but can also be a vertical, sloping or overhanging wall or ceiling surface.
• A post support for receiving a post end, which can be connected to the anchor element in such a way that it can be detached from it relatively easily and preferably without tools. The post carrier can otherwise be designed in any suitable manner for receiving the post end. In particular, it can have a sleeve into which the post end can be inserted.

The device is characterized in that the anchor element on its the upper side facing the post carrier is essentially flat and preferably without projections projecting in the direction of the post support is formed, and that it has recesses into which the Outgoing fasteners can intervene.

Such a device has the advantage that the anchor element is permanently on Can be fixed in place while the post support can only be fixed with the Anchor element is coupled. In the disassembled (i.e. from the post bracket separated) state, the anchor element remaining on the surface affects not annoying or tripping hazard as it is essentially flat is formed and has no upwardly projecting fasteners.

Preferably, the anchor element is slightly curved, so that in assembled state between its underside and the subsurface a cavity arises. This cavity offers space for penetrating through the anchor element Post bracket fasteners. Furthermore, the cavity ensures more stable, peripheral support of the anchor element as well as corrosion protection by the distance from the ground.

The post support of the device is preferably designed so that it in the assembled (i.e. connected to the anchor element) the Fasteners of the anchor element covered. In particular, the Post supports have a base plate that essentially covers the entire Anchor element covered. In this way, the fasteners fall visually not disturbing and are also protected against unauthorized access.

For the design of the detachable connection between post support and There are various options available for the anchor element. Preferably becomes a bayonet lock between the post bracket and the anchor element trained in the protruding from the post carrier in the recesses of the anchor element are inserted and these can reach behind. The dimensions and positioning of the protrusions and the recesses are in a suitable manner on each other vote. Furthermore, the projections and the recesses preferably arranged rotationally symmetrically with respect to the post axis, so that the bayonet lock is made by rotating it about this axis or can be solved.

According to a special embodiment of the bayonet lock, the Projections on the post support the shape of mushrooms and the recesses on Anchor element in the form of slots with a widened head area. The Mushroom projections can then pass through the head area of the slots with their heads passed through and then with the mushroom stem in the narrower slot be inserted.

In an alternative embodiment of a bayonet lock, the Post carrier L-shaped projections, which in the assembled state for Have anchoring element parallel legs. This leg can go through the slots of the anchor element are passed through and the anchor element reach behind for attachment with the post support.

As already mentioned, the bayonet catches are preferably like this designed that by a relative rotation between post support and Anchor element can be attached or detached. Advantageously, in In this case, an additional anti-twist device between the post support and formed the anchor element, which an unintentional release of the bayonet catch prevented from the attached state. The anti-rotation device can e.g. as a plug element (screw, plug pin, spring element or the like), which is formed by two in the assembled state aligned openings on the post support and anchor element can be performed.

In an alternative embodiment of the detachable connection between Post bracket and anchor element, the anchor element has at least one thread and the post support a corresponding and in the assembled state aligned hole, a screw bolt inserted through this hole and can be screwed into the thread. This kind of detachable Fastening has the advantage that there is not necessarily a (hollow) space for the Reaching behind the anchor element must be provided.

So that the anchor element is as inconspicuous as possible when disassembled and does not protrude as a trip hazard over the level of the rest of the subsurface the edge area of the anchor element preferably with one towards the ground sloping bevel. With a circular in plan view Anchoring element thus creates a frustoconical edge area. The The bevel can extend to the outermost edge line of the anchor element run. However, the outermost edge of the anchor element can also be used be formed by a flat edge strip.

There are various ways of attaching the anchor element to the subsurface Possibilities. The anchor element preferably has through bores, through which to be anchored or already anchored in the underground Fixing screws can be guided.

Alternatively, projections can be made on the underside of the anchor element Example in the form of bolts - be provided, which is anchored in the ground can be.

Figure 1 shows the preferred embodiment of the invention Fixing device 101 for a post (not shown) in one Exploded view. The fastening device 101, which is preferably made of forged, rolled or cast metal (steel, aluminum, Gray cast iron etc.) is essentially made up of two elements, namely the post support 102 and a flat anchor element 103.

The separately in Figure 4 in a view from above (left) or below (right) shown arched anchor element 103 has the shape of a geometrically on its underside open truncated cone with a very low height. The Tapered surface 107 forms a radial direction to the edge of the Sloping bevel towards the anchor element. This ensures that under the middle area of the anchor element relative to the flat surface (not shown) creates a cavity and the anchor element to the underground hugs without forming a trip hazard.

The anchor element is thus “essentially flat”, which is is particularly conditioned or defined by the fact that the anchor element is none Trip hazard on the floor and none when a foot appears unpleasant, sharp impressions in the sole of the foot. Furthermore, one "essentially flat" anchor element, preferably the upper side predominantly (e.g. over 80% of the area) even, with no projections or the like stick up. At the edge, the anchor element is preferred steplessly tapered on all sides (e.g. at an angle). The relationship of maximum height to the diameter of such an anchor element preferably between 1: 5 and 1: 100, particularly preferably between 1:10 and 1:50. The maximum height of the anchor element is typically less than 15 mm, particularly preferably less than 10 mm.

At the edge of the anchor element 103, three through holes are evenly distributed 105 provided by which the anchor element on a Underground such as the floor of a terrace can. Both head screws can be drilled from above with dowels screwed in as well as threaded bolts already fixed in the ground through the Through holes 105 are inserted and secured by nuts. The Area 126 around the through holes 105 is from the curvature of the Anchor element 103 excluded, so that the latter in these areas flat and is stable on the surface.

A central opening 108 (FIG. 1) of the anchor element 103 serves as Water drain.

Furthermore, the anchor element 103 has a uniform center point distributes three recesses in the form of arcuate slots 104 an enlarged, circular head portion 106. These keyhole-shaped Recesses form part of a bayonet lock between the post support 102 and anchor element 103.

The post support 102 consists essentially of a circular one Base plate 114, above which a sleeve 115 rises. In the Base plate 114 are various holes 110 made during the Production of the post support serve as a zinc drain. At the bottom of the Base plate 114 are also three mushroom-shaped projections 113 evenly distributed consisting of a mushroom stem 112 and a mushroom head 111 arranged. This represent the second part of the bayonet lock already mentioned. The Protrusions 113 may be integrally formed with the base plate 114, they but can also be screwed, riveted, welded or on otherwise be attached. The mushroom heads 111 can by the Head areas 106 are guided in the anchor element 103. Then the Post support 102 rotated relative to anchor element 103 about the post axis whereby the mushroom stalks 112 penetrate into the slots 104 while the Mushroom heads 111 engage behind the anchor element 103 from its underside. The Post support 102 can be done in this manner without tools by a simple Rotation a few degrees securely and stably connected to the anchor element 103 become. If the post carrier is not needed, it can be easily carried through a rotation in the opposite direction can be separated from the anchor element again, so that no disturbing object remains as a trip hazard on the ground.

So that the bayonet lock is not inadvertently, for example by Wind forces on a parasol that can be solved is one mounted Effective anti-rotation lock provided. This consists of one Through hole 124 (Figure 3) in the base plate 114 through which a Plug element guided into an aligned hole 109 of the anchor element 103 can be. Various examples of suitable plug elements are shown in FIG. 1 shown, namely a ball pin 120a, a hexagon screw 120b, a Eyebolt 120c, eyebolt 120d and wing screw 120e. Plug elements with a thread are in a corresponding Thread screwed into the anchor element, the latter e.g. in hole 109 can be cut or otherwise formed. Just like in Figure 4 shown the thread through a welded under hole 109 Mother 125 are formed. Figure 2 shows the preferred used Wing screw 120e in the assembled state of the fastening device in which it is screwed into the aforementioned nut 125.

The upstanding one is used to hold a post to be held Sleeve 115 of the post element 102. The sleeve has a known per se Way at its upper edge a radially inward ring or Eyebolt 116 on the thread of a welded nut 122 (Figure 3) and is used to insert objects into the sleeve 115 clamp. Furthermore, a sleeve 115 can be inserted into the upper opening Adapter 117 made of plastic for centering and various Reduction sleeves 118 (with a slot for the passage of the eyebolt 116) Plastic are used to make a post of a certain diameter to store safely. To protect against rain, the sleeve can be used when not in use closed at the top by a cover cap 119 made of plastic be, which with two hooks in the side holes 123 (Figure 3) of the sleeve is snapped into place.

As can be seen in particular from FIG. 2, the base plate of the Post carrier in the assembled state, the fastening screws of the Anchor element, so that they are protected and not visually disturbing emerge.

FIG. 5 shows one in a view from above (left) and below (right) alternative embodiment of an anchor element 103 ', in which the Bevel 107 at its outermost edge through a flat ring 126 is continued. The resulting additional ring surface serves the better support of the anchor element 103 'on a surface.

The alternative embodiments shown in Figures 6 to 23 are in Essentially the same as the first embodiment described so far. In the three-digit reference numbers therefore stands for the first digit for the respective Embodiment, while the remaining two digits represent comparable parts of the Embodiments are identical. In the following, only the respective

Differences in the embodiments explained.

In the second embodiment 201 shown in FIGS. 6 to 10 the post bracket 202 and the anchor element 203 also by a Bayonet lock connectable. The bayonet lock, however, will by circular arc-shaped slots 204 in the anchor element 203, which are evenly a circular line are distributed, and by L-shaped projections 213 on the Bottom of the base plate of the post bracket 202 realized. The Protrusions 213 consist of a connecting leg 212 and a Leg 211, which in the assembled state is parallel to the anchor element 203 extends and after passing through the slots 204 and a relative rotation between post bracket 202 and anchor element 203 the anchor element from below engages behind. The projections 213 can be shown at the edge of the Base plate of the post support. However, you can also in Be arranged inside the base plate, which has the advantage that it in the assembled state are covered.

Figures 11 to 14 show a third embodiment 301, in which similar as in the first embodiment, a bayonet locking by mushroom-shaped Projections 313 on the post support 302 and keyhole-shaped recesses 304, 306 is formed on the anchor element 303. As can be seen from FIG. 12, In this embodiment, however, the base plate 314 of the post support is also included a smaller diameter than the anchor element 303, so that it in particular, the through holes 305 in the anchor element are not covered.

FIGS. 15 to 19 show a fourth embodiment 401. In this In one embodiment, the base plate 414 of the post support 402 has three evenly distributed through holes 412, which in the assembled state aligned with holes 404 in the anchor element 403. As from Figures 18 and 19 can be seen, nuts 425 are welded to the underside of the holes 404. If the post support 402 is placed on the anchor element 403, can therefore screw elements 413a-413d inserted through the through hole 412 and screwed into the thread of nut 425. Preferably done this screw connection with wing screws 413d. Of course you could instead of the nuts 425, thread 404 directly in the holes be provided.

A fifth embodiment 501 is shown in FIGS. 20 to 23. Similar as in the fourth embodiment, the connection between Post support 502 and anchor element 503 using screw elements 513a-513d, which passed through through holes 512 in the post support and in one Threaded hole 504 of the anchor element 503 are screwed tight.

The peculiarity of the fifth embodiment is that the The underside of the anchor element 503 extends from three floor anchors 528, which in the The substructure must be fastened, for example, by concreting in. The floor anchors 528 have a thread on their upper side, with which they are screwed in Nuts 505, which are welded to the underside of the anchor element 503 (Figure 23), or in any other way formed on the anchor element 503 Thread can be screwed. The advantage of this embodiment is in that the anchor element 503 can be attached in a concealed manner.

Instead of the sleeve-shaped post support 102-502 shown in the figures could in principle also other known forms of post support can be realized, for example square or polygonal tubes or upwards protruding individual tabs.

Furthermore, in addition or as an alternative to the illustrated inputs and Attachments 117-119 (Figure 1) other accessories can be used. In particular, the clamping attachment 618a-618f shown separately in FIG a post bracket 615 can be used. This consists of one cylindrical base part 618e with an upward external thread 618d and a cap sleeve 618b, which has a sleeve formed thereon Internal thread can be screwed onto the external thread 618d. from The upper edge of the union sleeve 618b has several downward-running Clamping webs 618a, which at their lower end conically towards the center bend. When screwing the union sleeve 618b onto the base part 618e place the clamping webs 618a on a conical section 618c of the Base part 618e and are thereby pushed radially inwards so that they a rod inserted into the post support 615 (not shown) Clamp. The advantage of the clamping attachment, which is preferably made of plastic 618a-618f thus consists in the fact that it is fixing rods different diameters and, within limits, even different cross sections allows.

As can also be seen from FIG. 24, the base part 618e has on its lower end a sleeve-shaped section 618f of larger diameter, with which it overlaps the post bracket 615. Inward projections of the Sections 618f snap into holes 623 of the post support 615. alternative or in addition, section 618f can also be on post support 615 formed thread (e.g. a welded nut 622) overlap (not shown), so that a screw element (see number 116 in Figure 1) through a hole in section 618f can be inserted into the thread. The clamp attachment will hereby fixed particularly securely.
