Description

The invention relates to a device for the vertical attachment of a parasol underground and an associated method. Such devices are suitable, for example, for anchoring a mast of a parasol in the ground. They can be used for the reversible assembly and disassembly of parasols.

There are known ground mounts for parasols in the form of a sleeve anchored in the ground. The mast of the parasol can be inserted into the sleeve to attach the parasol. However, such ground attachments have the disadvantage that over time the ground can subside, which leads to an oblique orientation of the sleeve. In addition, an exactly vertical arrangement of the sleeve in the ground during assembly is necessary, which is associated with increased technical complexity.

Ground attachments known from the prior art often have flexible cover elements, for example made of elastomeric plastic, for covering the sleeve fastened in the ground. These can be designed to be foldable in order to easily expose the opening of the sleeve in order to insert the mast of the parasol. However, the flexible cover elements are often not able to absorb sufficient forces. This is the case in particular in the area of streets, sidewalks, pedestrian zones and the like. In addition, the flexible cover elements regularly detach from the sleeve, resulting in an unsecured opening in the floor. The use of comparable metal cover elements is not permitted in a wide range of applications due to safety problems

It is possible to firmly close the opening of such ground sockets, for example with firmly screwed metal cover plates. This provides a durable and secure cover but involves a significant amount of effort each time the parasol is set up and taken down. This is e.g. B. for gastronomic establishments in which parasols must be assembled and dismantled daily, not practical.

It is the object of the invention to provide a further developed device and an associated method for attaching a parasol.

The object is achieved by the device according to claim 1 and the method according to the independent claim. Refinements are specified in the dependent claims.

A device for the vertical attachment of a parasol is used to solve the problem. The device includes an outer mount for anchoring on or in a substrate and an inner mount for holding the sunshade with an opening for inserting the sunshade. The inner bracket is positionable inside the outer bracket and can be held by the outer bracket.

The device according to the invention decouples the part anchored in the ground from the sunshade to be fastened by the two holders arranged one inside the other. This makes it possible, for example, to influence the angle of the inner bracket to the outer bracket. In this way, an oblique orientation of a parasol can be corrected, for example as a result of subsidence. Any inaccuracies in the arrangement of the external bracket in the ground can also be compensated for. Greater tolerances are thus possible here, which entails a reduction in the technical complexity during assembly.

The device is suitable for vertical attachment of the parasol to the ground. Of course, the device can also be suitable for non-vertical, for example oblique, attachment of the parasol to the ground and/or for attachment to a wall. The device is used in particular for reversible attachment of the parasol so that, for example, regular assembly and disassembly is possible.

The device is suitable for attaching a parasol. In particular, the device is also suitable for fastening other objects. Other objects that can be attached with the device are, for example, an umbrella, a lamp post, a flagpole, a pole for an awning, a post for a traffic sign or any other pole or post. Basically, the device is used to attach a lower part of a mast of the sunshade or other object. Of course that is too Attachment of a transition pipe possible. Transition tubes are used to connect certain umbrellas to ground sockets at a desired height.

The external bracket is typically used for fixed anchoring in the ground with a substantially vertical orientation. Additionally or alternatively, anchoring to a substrate is possible. The orientation relates to a central longitudinal axis of the outer bracket, which defines the direction of longitudinal extent of the outer bracket. The fixed anchoring can be done for example by concreting. The outdoor bracket can be anchored in the ground, in or on a floor covering and/or in or on a building. The outside mount is designed to contact the ground with its outside and bottom and to be firmly anchored in it. The bottom of the outdoor mount can be open or closed. In this way, a fixed and permanent arrangement of the device and/or the external mount in the underground is achieved.

The inner mount is used to hold the sunshade, for example its mast or a transition tube that can be connected to the sunshade. Basically, the inner bracket is used to hold an elongated object that is to be fixed vertically in the ground. The inner bracket has an opening for inserting the mast. A large part of the parasol thus protrudes from the opening.

The inner bracket is a separate component from the outer bracket. The inner holder can be arranged at least partially and in particular completely inside the outer holder. In other words, it cannot be ruled out that a section of the inner mount, for example an upper section, protrudes from the outer mount when used as intended. In one embodiment, the inner holder does not protrude or does not significantly protrude from the outer holder when it is arranged in the outer holder.

When used as intended, the inner bracket is firmly attached to the outer bracket and/or the opening is approximately level with the surrounding ground. In other words, the device is below ground level. Its top can be flush with the ground surface. Thus, the sunshade or mast can be inserted from above into or through the opening in the inner holder, so that it is held by the inner holder.

In particular, the inner holder delimits a cavity for accommodating an area of the sunshade or the mast. For example, it can be designed in such a way that a lower part of the mast of the sunshade can be inserted with a precise fit into the cavity delimited by the inner holder, so that the sunshade is held by the inner holder in this way. The cavity may have a circular cross-section so that it can accommodate round parasol poles. Inside the cavity defined by it, the inner holder can have a support element, on which a lower edge of the sunshade can be supported when the sunshade is in the held state. The support element can be arranged in the lower area of the inner holder, for example at the lower end. The inner mount can have fastening means for fastening the sunshade, in particular for form-fitting fastening. For example, the inner holder can have a transverse bolt with which the mast of the sunshade can be connected by a bayonet catch and in this way secured against being pulled out.

The outer bracket can hold the inner bracket inside. The outer bracket and the inner bracket can therefore be rigidly connected to one another. The inner bracket is positioned inside the outer bracket and fixed there in this position. In one embodiment, the device is set up in such a way that the outer holder and the inner holder can be connected to one another in a non-positive and/or positive manner.

In principle, the inner holder and the outer holder can be moved relative to one another when they are not connected to one another. When held or connected, mobility is prevented. Holding or connecting fixes a relative position of the inner holder and the outer holder to one another. The connection is in particular a reversible connection. It can be designed as a screw connection. In one embodiment, the device comprises at least one fastener such as. B. a first screw for non-positive and / or positive connection of the outer bracket with the inner bracket. "Screw" within the meaning of the invention also includes threaded pins, also referred to as grub screws, and threaded bolts. In particular, however, the first screw has a head.

The inner mount and the outer mount are typically hollow bodies of different sizes. In particular, the inner holder and the outer holder each have an elongated shape. The inner bracket is typically dimensioned in such a way that it can be inserted into the outer bracket along its longitudinal direction. The inner bracket can then be connected to the outer bracket.

In one embodiment, the inner holder and/or the outer holder has a circular-cylindrical basic shape.

“Circular-cylindrical basic shape” means that there can be certain deviations from the circular-cylindrical shape, for example in the form of recesses, openings, add-on parts or the like. When used as intended, the basic shape is in particular aligned essentially vertically. In one embodiment, an outer wall and/or an inner wall of the inner bracket has a circular cross-section. In one embodiment, an outer wall and/or an inner wall of the outer bracket has a circular cross-section. In particular, the inner bracket is made from a tube. Alternatively or in addition, the outer bracket can be made from a tube. In this way, a very stable and durable device can be provided with little technical effort.

In one embodiment, the following applies to an inner diameter D _I,A of the outer holder and an outer diameter D _A,I of the inner holder: D _I,A =F * D _A,I . The following applies here: F≧1.3, in particular F≧1.5.

The inside diameter of the outer bracket is the diameter of the cavity enclosed by the outer bracket. This does not conflict with the fact that smaller diameters can be present in areas of the outer mount, for example in the area of a support element or a connecting area of the outer mount that protrudes radially inwards. In particular, the inner holder can be rotated about a vertical axis and/or pivoted about a horizontal axis in the cavity.

In one embodiment: F≧1.8 or F≈2. In other words, there is a clearance between the inner bracket and the outer bracket. This embodiment makes it possible to compensate for deviations in the angle between the inner bracket and the outer bracket, since the inner bracket can rotate inside the outer bracket over a wide range. This is also possible when the inner bracket and the outer bracket are long. This is advantageous in order to ensure particularly firm anchoring in the ground and/or a particularly firm hold of the sunshade to be fastened. In particular, the factor F is less than 10.

The outer diameter of the outer mount can be between 50 mm and 250 mm, in particular between 75 mm and 180 mm and for example approximately 80 mm or approximately 160 mm. The inner diameter of the outer mount can be between 50 mm and 250 mm, in particular between 80 mm and 180 mm. The inner diameter of the inner mount can be between 20 mm and 125 mm, in particular between 35 mm and 70 mm. Thus masts with the same or a slightly smaller outer diameter can be held. The outer diameter of the inner mount can be between 25 mm and 125 mm, in particular between 40 mm and 90 mm. The wall thickness of the inner holder and/or the outer holder can be between 3 mm and 10 mm, in particular between 4 mm and 8 mm.

In one embodiment, the device is set up in such a way that a non-positive and/or positive connection of the inner holder to the outer holder takes place using a plurality of first screws.

The inner bracket is therefore held by the outer bracket in a non-positive and/or positive manner. In particular, the inner bracket is firmly screwed to the outer bracket. At least three, in particular five, first screws are preferably provided. These can be distributed evenly over the circumference of the inner mount and/or the outer mount. The device may include the first screws. This ensures a smooth and solid connection between the outer bracket and the inner bracket. This design allows the device to be manufactured, assembled and adjusted with little technical effort.

In one embodiment, the first screws are aligned essentially parallel to a direction of longitudinal extent of the outer bracket. Essentially in parallel means, for example, that an angle between the first screws and the direction of longitudinal extension is not greater, ie 15° and/or 8°. In particular, the first screws are aligned vertically. This enables good accessibility even when assembled with a firm hold at the same time, so that the attachment can be guaranteed even with typical wind loads that act on the sunshade.

In one embodiment, the inner holder has a radially outwardly projecting flange for a non-positive and/or positive connection with the outer holder. In particular, a plurality of holes for locating first screws are arranged in the flange.

The flange is used for the non-positive and/or positive connection with the external bracket. It can therefore be connected in a non-positive and/or positive manner to a part of the outer bracket, in particular to a connection area of the outer bracket. The flange is preferably the only part of the inner bracket that serves to connect to the outer bracket and/or that contacts the outer bracket. The first screws are used for the non-positive and/or positive connection. In particular, the flange is arranged at an upper end of the inner bracket. Accordingly, an outer surface of the flange forms an axial boundary of the inner bracket. In particular, the flange extends perpendicular to the direction of longitudinal extent of the inner bracket.

The flange can have a basic shape in the form of a circular ring, in particular if the inner holder has a basic shape in the form of a circular cylinder. “Annular basic shape” means that there can be certain deviations from the annular shape, for example in the form of recesses, openings or the like. The flange can have recesses, for example, through which water can drain downwards. The flange protrudes radially outwards, starting from the wall of the inner holder that is aligned along the longitudinal extension of the inner holder. The flange does not necessarily have to be configured circumferentially, but can only be arranged in sections on the circumference of the inner holder. It can rest against an outer wall of the inner bracket.

In particular, the holes are configured as through holes. The holes are in particular essentially parallel to the longitudinal direction of the Inner mount aligned. Typically, the holes serve to push through the first screws, which are fastened in the threaded holes below in the external bracket. The holes can be designed as countersunk holes, so that a substantially flat surface can be ensured when the first screws are arranged in the holes. The holes can be designed in such a way, in particular by means of suitable diameters and suitable countersinks, that the first screws can be inserted through the holes at different angles. In this way, the flange and the connecting area can also be fastened in non-parallel relative angular positions to one another by means of the first screws. The angular positions each relate to the longitudinal extension directions of the inner and outer bracket.

In one embodiment, the outer bracket has a connection area that protrudes radially inward for the non-positive and/or positive connection with the inner bracket. In particular, a plurality of holes for arranging first screws are arranged in the connection area.

The connection area is used for the non-positive and/or positive connection with the inner bracket. It can therefore be connected in a non-positive and/or positive manner to a part of the inner holder, in particular to a flange of the inner holder. The connection area is preferably the only part of the outer bracket that serves to connect to the inner bracket and/or that contacts the inner bracket. The first screws are used for the non-positive and/or positive connection. In particular, the connection area is arranged in the area of an upper end of the outer bracket. A slight distance, for example between 3 mm and 30 mm, in particular between 5 mm and 15 mm, can be arranged between the upper end of the outer holder and the connection area. This enables the inner holder positioned inside the outer holder to be flush with the wall of the outer holder on the upper side.

In particular, the connection area extends perpendicularly to the direction of longitudinal extent of the outer bracket. The connection area can have a circular ring-shaped basic shape, in particular if the outer holder has a circular-cylindrical basic shape. The connection area protrudes from the area that is aligned in particular along the longitudinal extension of the outer bracket Wall of the outer bracket radially inwards. The connection area does not necessarily have to be configured circumferentially, but can only be arranged in sections on the circumference of the outer bracket. It can rest against an inner wall of the outer bracket.

The connection area is typically open radially inwards. In this way it allows the insertion of the inner bracket. In one embodiment, an inner diameter of the connection area is larger than an outer diameter of the inner bracket by a factor of between 1.005 and 1.15, in particular between 1.01 and 1.1 and in one embodiment between 1.03 and 1.08.

In particular, the holes are designed as threaded holes with an internal thread for fastening the first screws. Typically they are through holes. The holes are in particular aligned parallel to the direction of longitudinal extension of the outer bracket. Typically, they are used to attach the first set of screws that have been inserted through holes in the inner bracket, thus attaching the inner bracket to the outer bracket.

In one embodiment, the device has at least one adjustment means. The at least one adjustment means is set up to adjust a relative angle between the inner holder and the outer holder.

In particular, the adjustment means is arranged to be adjustable in the unconnected state, thereby defining an angle between the inner bracket and the outer bracket. This defined angle is then fixed by holding the inner bracket in the outer bracket. In other words, the relative position of the inner bracket to the outer bracket is fixed by the connection. For example, a wedge washer or one or more spacers can be used as the adjustment means. However, the adjustment means preferably comprise second screws, as explained below.

In one embodiment, the inner mount has a radially outwardly projecting flange and the outer mount has a radially inwardly projecting connection area. The flange and the connection area are used for the non-positive and/or positive connection of the inner holder with the outer holder. The at least one adjustment means is set up in different areas of the Flange and the connection area set different distances between the flange and the connection area.

In particular, the flange and the connection area are shaped in a substantially complementary manner. They can be in direct contact with one another, at least in certain areas, and/or their distance from one another can be set at least in certain areas by the at least one adjustment means. When used as intended, the flange and the connection area are preferably aligned parallel or at an angle of <15°, in particular <10° and typically <7° to one another. The angle is measured between the longitudinal direction of the flange and the longitudinal direction of the connection area, both of which are aligned approximately horizontally.

In a further embodiment, at least three adjustment means are provided. Each adjustment means includes a second screw and a threaded hole. The threaded hole is located in the flange of the inner bracket or in the connection area of the outer bracket. The second screw can be positioned in the threaded hole in such a way that it adjusts a distance from the respective other part depending on its longitudinal position.

A second screw can, for example, be in the form of a threaded pin, also referred to as a grub screw or worm screw. The second screws can be arranged in holes provided for this purpose in the flange or in the connection area and can be adjusted in their longitudinal position by turning. The free ends of the second screw are then supported on the surface of the other part and thus influence the distance. Due to the better accessibility at the top when the inner bracket is inserted, it is preferable to provide the holes for the second screws in the flange of the inner bracket so that the second screws are supported on the connection area of the outer bracket and in this way define the distance between the inner bracket and the outer bracket. Threaded pins have the advantage that they can be screwed all the way into the hole, allowing for a particularly wide adjustment range and a flush finish with the surface. At least three and, for example, five second screws are preferably provided, which are distributed evenly over the circumference of the flange or the connection area. In this way, a particularly easy adjustment of the angle in all Directions and any forces that may arise, for example as a result of wind loads, distributed to several second screws.

In one embodiment, the second screws are aligned essentially parallel to a direction of longitudinal extension of the outer bracket and/or essentially vertically. Due to the good accessibility, this enables a particularly simple adjustment of the angle.

In a further embodiment, the device has a closure part. The closure part has a cover element for at least partially closing the opening of the inner holder. The closure part also has a foot element, which is firmly connected to the cover element, for arrangement inside the inner holder.

The cover element serves to close the opening of the inner holder. In this way, for example after a sunshade has been taken down in the evening, the opening remaining in the ground can be closed securely and firmly. In particular, the cover element is made of metal, for example hot-dip galvanized steel, in order to meet the requirements with regard to its mechanical stability. In particular, the closure part and inner holder are designed in such a way that when the closure part is inserted into the inner holder, the cover element is flush with an outer surface of the inner holder. In particular, the outer surface is an upper surface of the flange of the inner bracket.

The cover element is typically set up in such a way that it largely closes the opening of the inner holder. However, it can itself have an opening, for example an access opening for removing the closure part.

The foot element is firmly connected to the cover element. It is placed inside the inner bracket and in this way holds the closure part. This prevents accidental removal of the closure part, for example due to negative pressure caused by vehicles driving over it. Devices designed in this way can be approved for public spaces and can therefore be used in a variety of ways.

This configuration brings with it the advantage that there is a secure closure of the opening, which can be inserted and removed manually in a simple manner and without tools. This makes handling much easier, particularly when it is inserted and removed regularly or daily. Even with an inclined orientation of the outer and/or inner mount, the cover element described can be securely flush with the ground surface and does not protrude beyond it.

In one embodiment, the foot element has a length L and the cover element has a maximum extent E _max . The following applies: L ≥ E _max .

The length of the foot element is measured along the longitudinal extension direction of the foot element between the two axial ends of the foot element. The maximum extent of the cover element is the length of the cover element measured in the plane of the cover element at the point of greatest extent. In particular, the diameter of the cover element is meant.

In other words, the vertical extent of the base element is greater than the horizontal extent of the cover element. This prevents accidental removal of the locking part due to tilting. The locking part is particularly firmly anchored. A particularly secure closure of the opening results.

In one embodiment, L≧1.2*E _max , in particular L≧1.5*E _max . In one embodiment, the length L extends at least 50% of the length of the inner bracket. In one embodiment, the foot element is dimensioned in such a way that it rests on a bottom part of the outer bracket or the inner bracket or on a support element of the inner bracket located in the lower area of the inner bracket.

In one embodiment, the foot element consists of a tube, in particular with a circular cross-section, or of four plate-shaped elements which are distributed essentially evenly in the circumferential direction and are firmly fixed to one another.

The foot element can therefore be cross-shaped or circular when viewed along its direction of longitudinal extension. Each of the plate-shaped elements is substantially perpendicular to the two adjacent ones plate-shaped elements aligned. Each pair of plate-shaped elements encloses an angle of 90°. For example, the base element can be composed of two metal plates arranged essentially perpendicularly to one another, which penetrate each other in the middle and in this way form the four plate-shaped elements. In particular, the plates or the plate-shaped elements are connected to one another by welding.

In this way, a foot element with great strength can be produced with particularly little technical effort. Due to its three-dimensional design, the foot element produced in this way can also be anchored in the inner holder in all radial directions, so that accidental removal of the closure part is effectively prevented.

In one embodiment, the inner holder and/or the outer holder has a length of between 25 cm and 80 cm. In particular, the length of the inner bracket and/or the outer bracket is between 35 cm and 60 cm.

The length is measured along the longitudinal direction of the inner or outer bracket. This configuration has proven to be optimal in terms of the balance between the strength of the parasol on the one hand and the use of materials, costs and effort on the other.

In a further embodiment, the outer holder has a foot part that projects radially outwards at one end. The foot part is used to set up the outdoor mount on a floor area. For example, the foot part is designed as a base plate.

The foot part is arranged in particular at the end of the outer mount opposite the connection area, that is to say at the lower end. It protrudes beyond the outer wall of the outer mount on at least one side, in particular on several different sides. A base plate protrudes in particular over the entire circumference of the outer wall. The base is used to set up the external bracket, for example on a floor area in an excavation, for the purpose of anchoring in the ground. For example, the outer bracket can thus be positioned at the desired location in a simple manner and without tilting prior to concreting a foundation for the outer bracket.

In a further embodiment, the inner holder and the outer holder are made of metal. In particular, the entire device is made of metal. Metal means a metallic material, i.e. it includes alloys. In particular, steel is used. The metallic material typically has an anti-corrosion layer. Hot-dip galvanized steel is preferred.

A further aspect of the invention is the use of a device according to the invention for fastening an object, such as a parasol, to the ground. All features, embodiments and effects of the device described above also apply to the use.

Another aspect of the invention is a method of securing an object, such as a parasol, underground. The device according to the invention is used in the method. The outdoor bracket is anchored on or in the ground. The inner bracket is positioned inside the outer bracket and held by the outer bracket. The object is inserted into the inner holder.

All features, embodiments and effects of the device described above also apply to this method and to the method for changing the angle described below. In particular, the method includes the non-positive and/or positive connection of the inner bracket to the outer bracket. In particular, the object is fastened to the inner holder. For example, a portion of the article may be received within a cavity defined by the inner mount. In this case, an outer contour of the object and an inner contour of the inner holder can be shaped complementarily, so that by simply inserting the object, it can already be held by the inner holder.

Another aspect of the invention is a method of changing the angle of an inner bracket. A device according to the invention is provided. Optionally, first screws are loosened at least partially, so that a connection between the outer bracket and the inner bracket is released. The length position of at least one second screw, in particular a grub screw, is adjusted in order to be in different areas of the flange and the connection area located distances between the flange and the connection area to affect. The first screws are then optionally tightened again. The adjustment of the longitudinal position of the at least one second screw causes a change in the angle between the inner bracket and the outer bracket.

Exemplary embodiments of the invention are also explained in more detail below with reference to figures. Features of the exemplary embodiments can be combined with the claimed subject matter individually or in a plurality, unless stated otherwise. The claimed scopes of protection are not limited to the exemplary embodiments.

figure 1 shows an outer bracket 10 of an exemplary embodiment of a device according to the invention for the vertical attachment of a parasol. The outer bracket 10 has a circular-cylindrical basic shape and is made of a tube 11 made of steel. The outer bracket 10 is used for anchoring in a substrate. For this purpose, it can be anchored in the ground in the upright orientation shown, so that the upper end face of the tube 11 is approximately flush with the ground surface. The central longitudinal axis 12, which corresponds to the direction of longitudinal extension of the outer bracket 10, is aligned approximately vertically. Of course, it is not excluded that the device can also be mounted at different angles.

On the underside, the outer holder 10 has a foot part that projects radially outwards, with which it can be positioned stably on a floor area for the purpose of anchoring in the floor. For example, it can be set up on the bottom of an excavation pit before concrete is cast around it. The foot part is designed as a base plate 19 which is welded to the lower end face of the tube 11 .

The outer bracket 10 is a hollow body and is used to hold an inner bracket inside it, which in turn holds the mast of a parasol or the like. For this purpose, the outer holder 10 has a radially inwardly projecting connection area 14 with which it can be connected to the inner holder in a non-positive and/or positive manner. The connection area 14 is designed as a steel ring, which is aligned perpendicularly to the central longitudinal axis 12 and is welded to the inside of the tube 11 . The steel ring has a thickness between 5 mm and 20 mm. In the embodiment shown here, the connection area 14 is designed to be circumferential.

The connecting area 14 defines an opening 18 in its radial interior, through which the inner bracket can be inserted from above. The connection area 14 is arranged in the area of the upper end of the outer bracket 10 . However, there is a distance of about 10 mm between the upper edge of the outer bracket and the connecting area 14 , which is measured parallel to the central longitudinal axis 12 . In this way, there is a free space 15 inside the outer holder 10 in the area in which the wall of the outer holder 10 protrudes axially beyond the connection area 14 . A flange of an inner bracket can be placed in this area so that the top surfaces of the outer bracket 10 and the inner bracket are flush with each other.

In the connection area 14 five holes 16 are arranged, which are evenly distributed over the circumference. These are designed as through holes and each have an internal thread so that the flange of the inner bracket can be attached to the connection area 14 with suitable first screws. Recesses 17 are also arranged in the connection area, through which water penetrating in the installed state can flow off.

An exemplary embodiment of a corresponding inner bracket 20 is in figure 2 shown. The inner holder 20 also has a circular-cylindrical basic shape and is made of a tube 21 made of steel. This has a significantly smaller diameter than the tube 11 of the outer bracket. The central longitudinal axis 22, which corresponds to the direction of longitudinal extent of the inner holder 20, is aligned vertically when used as intended. The inner holder 20 is a hollow body and has a central opening 28 at its upper end, through which the parasol pole or a comparable object can be inserted in order to be held by the inner holder 20 .

The inner bracket 20 is designed to be mounted inside an outer bracket, such as in figure 1 shown, arranged and held there. For this purpose, the inner bracket 20 has an outwardly protruding flange 24 which can be connected in a non-positive and/or positive manner to the connection area of the outer bracket. The flange 24 is designed as a steel ring, which is aligned perpendicularly to the central longitudinal axis 42 and is welded to the upper end face and/or to the outer wall of the pipe 21 . The steel ring has a thickness between 5 mm and 20 mm. The thickness corresponds in particular to the thickness of the connection area of the outer bracket. In the embodiment shown here, the flange 24 is configured circumferentially.

In the flange 24 five holes 26 are arranged, which are distributed evenly over the circumference. The positions of the holes 26 correspond to the positions of the holes in the connection area of the outer bracket, so that the holes of both elements are superimposed when used as intended. The holes 26 are countersunk so that on the one hand the heads of the first screws can be countersunk and can be flush with the top of the flange 24 . On the other hand, the countersinking also allows the first screws to be arranged in orientations that deviate from the completely parallel orientation to the central longitudinal axis 22, without parts of the screw head protruding beyond the upper side of the flange. In this way, the outer bracket can hold the inner bracket 10 at different angles, as shown in FIGS Figures 5 and 6 shown. The holes 26 are designed as through holes and in particular without an internal thread, so that first screws, which are screwed into the underlying holes in the outer bracket, can be inserted through the holes 26 .

In the area of the connection between the flange 24 and the tube 21 a free space 25 is formed, in which a cover element of a closure part can be positioned in order to at least partially close the opening 28 . The free space 25 is formed in that the diameter of an inner opening of the flange 24 is larger than the inner diameter of the pipe 21 and the flange 24 is welded to the pipe 21 in such a way that it protrudes beyond this by a certain length. This length is between 3 mm and 30 mm, in particular between 5 mm and 15 mm and in the example shown here approximately 10 mm. In one embodiment, the length corresponds to the thickness of the flange . A flush termination of the cover element with the top of the flange 24 is possible. At the same time, a lid member can be placed on the upper end of the tube 21 and held by the tube 21 . Forces occurring when the cover element is loaded are introduced into the tube 21 and via this into the outer bracket, which is firmly anchored in the ground.

In addition to the holes 26 in the flange 94 five threaded holes 44 are arranged. These are also distributed evenly over the circumference and are each arranged centrally between two holes 26 . The threaded holes 44 are used to accommodate second screws, here grub screws, with which an angle between the connection area of the outer bracket and the flange 24 can be adjusted. This is in the Figures 5 and 6 illustrated and detailed below.

the Figures 3 and 4 show a closure part 30 for closing the opening of the inner holder. figure 3 shows the closure part 30 obliquely from above, while figure 4 the closure part 30 shows obliquely from below.

The closure part 30 comprises a cover element 32 with which the opening of the inner holder can be closed at least partially. This is advantageous and usually prescribed in publicly accessible areas if no parasol or the like is held by the device. This is the case, for example, when parasols in gastronomic establishments are taken down overnight. In this case, for safety reasons, the opening in the floor needs to be sealed, which on the one hand can withstand mechanical loads and on the other hand is protected against unintentional removal. However, the opening in the inner holder is not completely closed, since also in the radial interior of the cover element 32 in turn, an engagement opening 38 is arranged. This is used for the uncomplicated removal of the closure part 30, for example when a parasol is to be set up. The access opening 38 has a diameter of a few centimeters, which can also be used without restriction in public traffic areas.

To close the opening in the inner bracket, the closing part 30 is inserted into the opening from above. A radially outer area of the cover element 32 comes to rest in the above-described free space 25 of the inner holder and is thus supported on the tube of the inner holder. At the same time, the upper side of the cover element 32 is flush with the upper end face of the tube of the inner holder.

The cover element 32 is designed as a circular disk. The closure part 30 also has a foot element 34 which is welded to the cover element 32 and protrudes downwards from the cover element 32 along its longitudinal extension direction defined by its central longitudinal axis 33 . Like the cover element 32, the foot element 34 is made of steel.

The foot element 34 consists of four plate-shaped elements 36 distributed substantially evenly in the circumferential direction, namely steel plates which are firmly fixed to one another by welding. In the viewing direction along the central longitudinal axis 33, it is thus designed in the shape of a cross. It is irrelevant whether, to produce the base element 34, two centrally penetrating steel plates are positioned perpendicular to one another and welded to one another, or whether the base element 34 is composed of four individual plates. As also in figure 4 As can be seen, the plate-shaped elements 36 have respective recesses in the area at the top center, so that reaching into the engagement opening 38 is facilitated. In addition, the width of the plate-shaped elements 36 decreases downwards, so that the base element 34 has a conical shape overall, which facilitates insertion into the inner holder. Deviating from the embodiment shown here, however, the foot element 34 can also be made of a tube, for example, which extends along the central longitudinal axis 33 .

The cover element 32 has a maximum extent E _max , which here corresponds to the outer diameter of the circular disc measured perpendicularly to the central longitudinal axis 33 . The foot member 34 has a length L between the connection area with the Cover element 32 and the lower axial end of foot element 34 is measured, as in FIG figure 4 shown. The length L of the foot element 34 is a multiple of the maximum extension E _max of the cover element 32. In this way, the closure part 30 is prevented from being removed from the interior holder unintentionally if the closure part 30 tilts inside the interior holder.

the Figures 5 and 6 show the use of the device 1 according to the invention in a simplified schematic representation. A sectional drawing of the device 1 is shown in each case, in which the inner holder 20 is arranged inside the outer holder 10 . In this case, the flange 24 of the inner holder 20 is supported radially circumferentially on the connection area 14 of the outer holder 10 . The opening 28 of the inner holder 20 is free, so that a parasol can be inserted from above. The device 1 is anchored in the ground and the upper edge of the flange 24 is at the level of the ground surface 50. For the sake of simplicity, the illustration of the free space in the region of the connection between the flange and the pipe, as shown in FIG figure 2 is shown omitted.

In figure 5 the outer bracket 10 and the inner bracket 20 are aligned coaxially so that their respective central longitudinal axes 12, 22 are superimposed. This state is present, for example, immediately after installation of the device 1 in the ground. Over time, subsidence can occur, so that the entire device 1 tilts. This results in tilted parasols, which is undesirable. Such an oblique position can be as in figure 6 shown can be corrected.

For this purpose, the device 1 has adjustment means 40 with which the angle between the outer holder 10 and the inner holder 20 can be adjusted. The adjustment means 40 each include a threaded hole 44 and a matching second screw 42, here in the form of a grub screw. The threaded holes 44 are, as in figure 2 , shown located in the inner bracket flange 94 so that the grub screws are accessible from above. In the Figures 5 and 6 the sectional plane runs through an adjustment means 40 that is shown on the left-hand side.

In figure 5 are all grub screws in the same length positions (axial positions), so that the flange 24 is aligned parallel to the connection portion 14. In figure 6 on the other hand, the outer bracket 10 has tilted by a few degrees. Out of For this reason, the length positions of the individual grub screws have been adjusted so that the inner bracket is still horizontal. It can be seen that a first distance A1 shown on the left side between the flange 24 and the connection area 14 is less than a second distance A2 shown on the right side between the flange 24 and the connection area 14. The central longitudinal axes are also 12, 22 clearly arranged at an angle to each other. In figure 5 on the other hand, the distances A1 and A2 are equal.

The cutting plane of Figures 5 and 6 also passes through a first screw 46 for attaching inner bracket 20 to outer bracket 10, shown on the right-hand side of each. The first screws 46 each pass through the in figure 2 shown hole 26 of the inner bracket 20 and threads into the threaded hole 16 of the outer bracket shown in figure 1 is shown. It can be seen that a fixed connection of the inner bracket 20 to the outer bracket 10 is possible in both relative angular positions.

To correct the angle between the inner bracket and the outer bracket, the first screws 46 are at least partially loosened, the length position of at least one second screw 42 is adjusted and the first screws 46 are then tightened again.

figure 5 also shows two further features of the invention. On the one hand, an inner diameter D _I,A of the outer holder 10 and an outer diameter D _A,I of the inner holder 20 are shown. It can be seen that D _I,A is significantly larger than D _A,I . For example, the inner diameter D _I,A of the outer bracket is 80 mm and the outer diameter D _A,I of the inner bracket is 160 mm. Thus the factor F=2. The wall thickness of the inner holder and the outer holder is, for example, 5 mm each.

In addition, a transverse bolt 27 is shown, which is arranged in the lower area of the tube of the inner bracket 20 and is firmly connected to the inner bracket 20 . It is not excluded that the transverse bolt 27 is rotatable about its longitudinal axis. Corresponding recesses are arranged in the lower area of a mast of an associated parasol. By rotating the mast axially, the recesses on the transverse bolt 27 can be hooked in the manner of a bayonet catch, so that a form-fitting connection is produced. To this A parasol can be connected particularly firmly to the device 1 in this way.

figure 7 shows another embodiment of the device. In order to avoid duplication, the differences to the examples shown above are discussed in particular. Here, too, the closure part 30 of the device comprises a cover element 32 with an access opening 38 and a foot element 34. However, the foot element 34 is also designed here as a steel tube with a circular cross section. At its lower end facing away from the cover element 32, it comprises two recesses 39 lying opposite one another, which can be latched to the transverse bolt of the inner holder 20 in the manner of a bayonet catch. However, the recesses are designed obliquely in such a way that insertion and fastening can be carried out without tools if necessary, since the inclination of the recesses relative to the vertical is small and thus the rotation of the closure part about its central longitudinal axis is promoted by the downward weight force. On the other hand, it can only be pulled out with a rotary movement and with an appropriate auxiliary device (key). The closure part 30 shown can thus be attached particularly securely.

In addition, the outer bracket 10 includes a floor bracket 40 attached to the floor plate 19. This includes four threaded rods and a cross-shaped support structure made of two connected steel beams, which can be placed on a floor. The threaded rods each connect a corner of the floor slab at a variable height to one of the steel girders. In this way, the position of the outer bracket 10 can be set particularly precisely and variably during assembly, for example before concreting.

the Figures 8A and 8B show an inner holder 20 with inserted closure part 30, in particular according to the embodiment figure 7 . In Figure 8B the inner bracket 20 is not shown in order to show the arrangement of the cross bolt 27 in the closed position of the recess 39. In Figure 8A the cover element 32 of the closure part 30, which is arranged and fastened in the inner holder 20, is visible from below.

The engagement opening 38 is slot-shaped so that a flat, T-shaped tool can be inserted from above to remove the locking part 30 from the inner holder 20 . The auxiliary device can, for example, consist of a curved and/or welded steel rod, the diameter of which is less than the slot width of the engagement opening 38. During insertion, the crossbar of the "T" points downwards. When the auxiliary device is rotated 90° counterclockwise, the two legs of the cross brace abut respective extended stops 56 of the contact structure 52 provided for this purpose and are thereby aligned in their angular position. By subsequently lifting the auxiliary device, the legs of the transverse strut come to rest in respective bearing bays 54 of the bearing structure 52, so that the closure part 30 is connected to the auxiliary device in a rotationally fixed manner. The closure part 30 can be removed from the inner holder 20 by further lifting and then simultaneously rotating and lifting the auxiliary device with the closure part 30 according to the shape of the recess 39 .

To fasten the closure part 30, the auxiliary device is also positioned in the contact bays 54 as described. The closure part 30 is then inserted into the inner holder and rotated in the reverse order to that for removal. Here, the shape of the recess 39, as described above, contributes to easy insertion. If necessary, in addition to the weight, a compressive force can be exerted directly on the cover element 32 from above, e.g. B. with the foot. <b>Reference List</b> contraption 1 outdoor mount 10 Pipe 11 central longitudinal axis 12 inner diameter D _I,A connection area 14 free space 15 Hole 16 recess 17 opening 18 bottom plate 19 interior mount 20 Pipe 21 central longitudinal axis 22 outer diameter D _A,I flange 24 free space 25 Hole 26 cross bolt 27 opening 28 locking part 30 cover element 32 central longitudinal axis 33 foot element 34 length L Maximum Extension max plate-shaped element 36 access opening 38 recess 39 adjustment means 40 Second screw 42 threaded hole 44 First screw 46 floor mount 48 Distance A1 Distance A2 terrain surface 50 investment structure 52 investment bay 54 attack 56
