Description

The invention relates to an adapter element for fastening a functional post, in particular a measuring post or traffic sign support post, to a base and a functional post system with such an adapter element, a functional post and a post close to the ground or anchored in the ground.

Danger levels are defined from the guidelines for passive protection on roads by vehicle restraint systems, FGSV, 2009 edition, as well as criteria for the classification of sign posts in the respective risk levels. For example, signposts for small or medium-sized traffic signs (tubular posts and fork stands made of steel tubes with an outside diameter >76.1mm and wall thicknesses >2.9mm, or made of aluminum tubes >76.0mm and wall thicknesses >3.0mm) are defined as deformable but not circumventable and are assigned to risk level 4.

The pamphlet AU2007229414A1 discloses an adapter for mounting posts of variable diameter in a ground socket, for example for selectively placing a rotary clothes dryer or a parasol in the same ground socket.

From the DE 20 2004 004 347 U1 construction site signage is known, consisting of a support foot and a shaft tube for a traffic warning sign, which is connected to the support, an adapter being arranged between the support foot and the shaft tube, the support foot being designed as a post guide foot which is screwed into the ground, and wherein the lower part of the adapter can be inserted into the open end of the carrier foot and is adapted to the inner shape of the carrier foot and that the adapter has an at least partially continuous recess, the shape of which is adapted to the shape of the shaft tube of a signage.

DE 94 19 365 U1 discloses a tube post construction with a joint bearing with which a deflection of the tube post is avoided when forces act radially on the tube.

DE 82 19 817 U1 describes traffic sign carriers with a carrier tube for the traffic sign, with a receptacle firmly anchored in the ground and with an intermediate sleeve which is plugged together and connected at one end to the receptacle and at the other end to the carrier tube. In this way, a predetermined breaking point is created in the area of the greatest bending moment between the lower edge of the support tube and the upper edge of the floor receptacle.

The object of the invention is to create an advantageous possibility for fastening a functional post.

Embodiments and objects according to the invention which are suitable for solving this problem are specified in particular in the claims.

The object is achieved according to the invention by an adapter element for attaching a functional post, in particular a measuring post or traffic sign support post, to a post anchored in the ground or near the ground, which is rigid and has a first tubular area for attaching the functional post to the adapter element and a second tubular area for attachment of the adapter element on the base, wherein the first area has a first cross section and wherein the second area has a second cross section and wherein the first cross section has a greater extent than the second cross section, at least in one spatial direction.

In this way, an adapter element is created with which a base can be connected to a functional post, with the cross sections of the base and the functional post being able to differ in size at least in one spatial direction. As a result, for example, a cross section of the base that is smaller in one spatial direction and a cross section of the functional post that is larger in the same spatial direction can be provided and connected to one another by the adapter element. In particular, the larger cross section of the first cross section in this spatial direction can result in the area moment of inertia of the first cross section being greater in this spatial direction than the area moment of inertia of the second cross section. In addition, when a motor vehicle drives onto a base with a cross section that is reduced in this way compared to the functional post, the base offers less resistance to the motor vehicle than a continuous post anchored in the ground with the larger cross section of the functional post. This can reduce the risk to traffic compared to a continuous post. At the same time, the stability of the functional post in relation to weather influences is not or only slightly impaired. Rigidly designed is to be understood as meaning that the first and the second area are firmly connected to one another and are essentially not flexible in relation to one another or individually. Posts close to the ground are to be understood in particular as meaning posts that are not themselves anchored in the ground, but rather, for example, with a wide one ren in the ground or can be connected to a post attached to a wall.

In an advantageous embodiment of the invention, the first cross section has a larger cross-sectional area than the second cross section.

In this way, a post anchored in the ground or arranged close to the ground with a smaller cross-sectional area and a functional post with a larger cross-sectional area can be connected to one another. The resistance of the post system that can be produced in this way to a motor vehicle crashing into the post system can be reduced as a result.

Furthermore, it is advantageous if the first cross section and/or the second cross section is a circular or oval or polygonal cross section,
and or
wherein the first cross-section and the second cross-section are substantially identical in cross-sectional shape.

The provision of circular, oval or polygonal cross-sections allows the use of commercially available functional posts and a post which forms a base and is close to the ground or anchored in the ground. Circular cross-sections are particularly advantageous when the resistance of the post to impact should be the same in all directions. Identical cross-sections allow the resulting area moments of inertia of the first and second areas to be coordinated very easily with one another.

In addition, it can be advantageous if the first cross section has a first diameter, in particular an outer diameter, and that the second cross section has a second diameter, in particular an inner diameter, with the first diameter being larger than the second diameter

In this way, the second area can be plugged onto a post forming the base and a functional post can be plugged onto the first area.

In a further advantageous embodiment, the second region has an outside diameter, the outside diameter not exceeding a value of 76.1 mm, in particular 76.0 mm, at any point.

Below such an outer diameter, the adapter element is particularly advantageously equipped with reduced resistance to the impact of a motor vehicle.

A further advantageous embodiment of the invention includes that the first area is designed to be inserted or pushed into the functional post,
and or
that the second area is designed to be plugged or pushed onto a ground-level post of the base.

In this way, the assembly of the adapter is simplified and the load capacity of the ground-level post is increased by the weight of the overall construction.

It can also be advantageous to provide a support structure on the adapter element, which is designed to support the functional post against the direction of gravity, in particular with the support structure being integrally formed on the adapter element.

As a result, the function post can sit stably on the adapter element. A one-piece, molded support structure allows the adapter element to be manufactured as an injection molded part or in another suitable manufacturing process.

Furthermore, it is advantageous to connect the first area to the second area by a transition area in which an outer diameter of the adapter element widens from the second area to the first area, in particular the support structure being formed by the transition area.

In this way, the adapter element has a high level of stability and enables favorable introduction of the weight exerted by the functional post into the adapter element and into the post close to the ground.

A further advantageous embodiment defines that the first area has at least one, in particular two, three or more ribs oriented in the longitudinal direction of the first area, in particular the ribs being integrally formed on the adapter element.

Such ribs simplify the attachment of the functional post, in that the first area does not rest against an inner wall of the functional post over its entire surface, but only through the ribs. In addition, the first area is reinforced by the ribs.

Furthermore, the first area and the second area, in particular also the transition area, preferably the complete adapter element, can advantageously be formed in one piece.

A particularly stable adapter element that is suitable for exactly one application is thus provided.

In a further advantageous refinement, the adapter element comprises a plastic material which is produced in particular as a plastic injection molded part.

In this way, the adapter element can be manufactured inexpensively and in large numbers.

• - einen auf den ersten Bereich aufgesteckten oder aufgeschobenen Funktionspfosten;
• - einen bodennahen oder im Boden verankerten bildenden Pfosten, auf den der zweite Bereich aufgesteckt oder aufgeschoben ist.

The object is also achieved by a post system with an adapter element according to one of the preceding claims, further comprising:

• - a functional post plugged or pushed onto the first area;
• - a forming post that is close to the ground or anchored in the ground, onto which the second area is attached or slid.

When a motor vehicle drives into the post system in the area of the post close to the ground or anchored in the ground, such a post system has a reduced resistance to the impact and consequently bends more easily. This reduces the deformation of the motor vehicle and improves the occupant protection for the vehicle occupants. This is especially true when compared to a continuous functional post anchored to the ground. At the same time, the stability of the functional post against the effects of the weather is essentially retained.

An advantageous development results when the post that is close to the ground or anchored in the ground does not exceed a maximum outer diameter of 76.1 mm, in particular 76.0 mm, at any point, in particular is matched to the inner diameter of the second area, so that a firm fit in form a loose fit is achieved between the second area of the adapter element and the post that is close to the ground or anchored in the ground,
and or
that the post that is close to the ground or anchored in the ground does not exceed a maximum wall thickness of 3.00 mm, in particular 2.9 mm.

A post system designed in this way has an advantageously low resistance to the impact of a motor vehicle, as a result of which the risk of injury to the vehicle occupants is reduced.

A further advantageous embodiment is formed in that the adapter element is releasably connected to the post near the ground or anchored in the ground, in particular by means of a screw connection, and the adapter element can be adjusted in height relative to the post near the ground or anchored in the ground by means of the releasable connection.

In this way, for example, traffic signs or information carriers that are attached to the functional post can be precisely adjusted in height.

A further advantage is achieved if an upper edge of the post that is close to the ground or anchored in the ground is arranged vertically below a lower edge of the functional post.

In this way it is ensured that the enlarged cross section of the functional post only begins at a defined height and does not unintentionally contribute to an impact resistance of the post close to the ground.

Furthermore, an advantageous post system is distinguished by the fact that it can no longer be assigned to risk level 4 according to the guidelines for passive protection on roads using vehicle restraint systems, FGSV, 2009 edition.

This reduces the risk to occupants of vehicles that may collide with the post system.

the 1 shows a post system 10 with an adapter element 20, which is used to connect a functional post 16 to a ground-level post 12, which can also be anchored in the ground or in a foundation. The adapter element 14 has a first region 20 and a second region 36, each of which has a tubular cross-section. The second area 36 is dimensioned such that an inner diameter D ₂ of the cross section of the second area 36 is adapted to an outer diameter of the ground-level post 12, so that the adapter element 14 can be plugged onto an upper end area of the ground-level post 12 and, in the plugged-on state, firmly on the ground-level post 12 sits.

The second area 36 has openings through which fastening elements 24 can extend. By means of the fastening elements 24, for example, a clamping fastening between the second region 36 and the post 12 close to the ground can be implemented. For example, with the help of clamping shoes, not shown, which are slidably mounted in a suitable longitudinal groove of the post 12 near the ground and which can establish a clamping connection between the second region 36 and the post 12 near the ground with the fastening elements 24 . As a result, the adapter element 14 can be adjustable in its vertical position relative to the post 12 close to the ground.

The first area 20 of the adapter element 14 has an outer diameter D ₁ which is adapted to an inner diameter of the functional post 16 so that the functional post 16 can be pushed onto the adapter element 14 and is firmly seated on the adapter element 14 in the pushed-on state.

The first area 20 has ribs 28 oriented in the longitudinal direction of the adapter element 14 , which make it easier to attach the functional post 16 and form a stiffening of the first area 20 .

A transition area 38 of the adapter element 14 connects the first area 20 to the second area 36. The transition area 38 has a conical shape, which forms a circumferential support structure 18 in the form of a shoulder at the lower end of the first area 20.

In the plugged-on position, the functional post 16 sits on the support structure 18 , which thus forms a delimitation for the functional post 16 in the vertical direction. The functional post 16 can also have a through-opening 26 . Fastening element 22, for example a screw with a pressure distribution sleeve, can be provided in order to fix the functional post to the first region 20. The screw of the fastening elements 22 extends through the through hole 26 and engages in the fastening opening 32 in which a thread for a corresponding thread of the screw can be provided. The fastening opening 32 is arranged in the area of a rib 28 so that the functional post 16 can be prevented from being pressed in or bent.

2 shows a side view of the adapter element 14. The tubular second area 36 defines an outside diameter D _outside and an inside diameter D ₂ , the outside diameter D _outside not exceeding a diameter of 76.1 mm or 76.0 mm and the wall thicknesses of the second area 36, possibly in total with a wall thickness of the ground-level post 12, does not exceed a value of 3.0 mm or 2.9 mm.

In the transition region 38 of the adapter element 14 there is also a recess (material protrusion) 30 .

3 shows a view of the adapter element 14 from below. It can be seen here that the inner wall of the tubular, second region 36 has a number of grooves 42 extending in the longitudinal direction of the adapter element 14 . In 1 it can be seen that the post 12 close to the ground has ribs 44 corresponding thereto in the longitudinal direction. When the second region 36 is pushed onto the post 12 near the ground, the ribs 44 engage in the grooves 42 and are guided by the grooves 42 in the longitudinal direction of the post 12 near the ground. The grooves 42 and ribs 44 form an anti-twist device, so that the adapter element 14 cannot rotate around the post 12 near the ground that is anchored in the ground.
