DE102008045788A1 - Fastening element for connecting official goods, has embedding sleeve inserted in ground, and two-part connection piece contains insertion part projecting in opening of object - Google Patents

Abstract

The fastening element (1) has an embedding sleeve inserted in a ground. Two-part connection piece (1a) contains an insertion part (5) projecting in an opening of an object such as bollard, street furniture, street sign and playground equipment. A holding piece (6) is locked in an embedding sleeve and is fixed between a flexible buffer (7) that is made from polyurethane and the insertion part.

Description

The The invention relates to a fastener for connection of public objects such as bollards with and without lighting, street furniture, street signs, Playground equipment u. Like. With a used in the soil Embedding casing.

In order to be able to remove such public objects for specific purposes, these are preferably inserted into embedded in the bottom Einbetthülsen and preferably detachably connected thereto by means of a special tool. Such an object is, for example, in the DE 100 10 449 C1 described bollards.

adversely in this bollard, as in many other public Items, however, is the rigid connection between Ground socket and bollard. For example, if the bollard of a motor vehicle is approached, the bollard can very easily the ground sleeve are torn from the ground, the Bollards then mostly crooked. It may well become one Tear off the bollard come. In both cases but then replacement must be procured, which is mostly must be financed by taxes or the like, since the respective polluter does not indicate the damage and he very often can not be determined is.

From the EP 0 077 313 A1 For example, an article is known which has a flexible connection of the type which allows the article to bend in a desired direction and, after kinking, to return to the original position. The article of this invention is intended primarily for use as a slalom pole. The construction of the flexible connection is hardly suitable, for example, in bollards o. The like. Objects to be used, since on the one hand, the pressure load and the resistance of the steel springs is too low. On the other hand, the entire construction is too complicated and appears very costly.

Of the Invention is the object of a fastener of specified genus, with which a flexibility even with public objects, such as bollards with and without lighting, street furniture, street signs, Playground equipment u. Like. Is achieved by the greater damage at the objects and thus also costs for the replacement of the objects largely avoided become.

These The object is achieved by a fastener solved with the characterizing features of claim 1.

expedient Further developments of the invention are in the subclaims characterized.

By the use of an elastic buffer on the fastener becomes a flexible storage of public goods, like bollards with and without lighting, street furniture, street signs, Playground equipment u. Like. Achieved so that larger Damage to the objects, for example as far as possible avoided by unintentional start become. This also reduces new or replacement purchases of Objects, which leads to enormous cost savings.

The Fastener can be used on many different in the ground Einbetthülsen used fastenable objects become. In addition to the items already mentioned Can these garbage containers, flagpoles, bollards with and without lighting, tree guard, parking lot limits, Street lights, etc. Even with guardrails that can Fastening element can be used, whereby by the elasticity energy is absorbed in an accident.

Further The fastener can also be used to secure buildings be used against shocks.

Further Advantages of the invention will become apparent from the following description based on a reproducing the invention and shown in the drawing Embodiment. It shows

1 a longitudinal section through a fastener according to the invention,

2 a plan view of the fastener after 1 .

3 in longitudinal section, the fastener in cooperation with a bollard and the Einbetthülse after tightening the clamping cone,

4a the embedded insert sleeve with fastening element and bollard in exploded view,

4b the paving sleeve inserted in the ground with a composite fastener and bollard before insertion into the potting sleeve,

4c the paving sleeve inserted in the ground with the fastening element inserted into it and twisted against it before the bollard is set up,

4d the inserted in the ground Einbetthülse with the attached and attached bollards and

4e the bollard with the fastener mounted in the Einbetthülse in tilted position.

That in the 1 to 3 illustrated fastener 1 is for connecting public objects, such as bollards with and without lighting, street furniture, street signs, playground equipment u. Like. With one in the ground 2 inserted Einbetthülse 3 intended. Below is an example of the fastener 1 the example of a bollard to be attached 4 further explained.

The fastener 1 has a two-piece connector 1a on, from one into an opening 4a of the bollard 4 protruding insert 5 and one in the Einbetthülse 3 lockable holding piece 6 consists. The holding piece 6 is between an elastic buffer 7 and the plug-in part 5 over a the buffer 7 and the holding piece 6 penetrating and in the plug 5 held screw 8th o. Like. Fastened clamped. There is the elastic buffer 7 preferably made of polyurethane. That to the holding piece 6 directed end 9 of the plug-in part 5 is preferably formed spherical segment and in a spherical segment-shaped depression 10 of the holding piece 6 stored.

So that the elastic buffer 7 can be optimally biased, is between the same and the head 11 the screw 8th a disk 12 provided, whose outer diameter is approximately the diameter of the buffer 7 equivalent.

After anchoring the Einbetthülse 3 , advantageous in concrete is the fastener 1 with the holding piece 6 over longitudinal grooves 13 (please refer 3 ) in the Einbetthülse 3 plugged in and coupled by a rotation of 90 ° bayonet-like. This cams engage 14 (see in particular 2 ) of the retaining piece 6 in a corresponding inner circumferential groove 15 the embedment sleeve 3 one.

After that, the bollard 4 with the opening 4a on the plug 5 of the fastening element 1 set up so that conical cross bores 16 of the bollard 4 (please refer 3 ) with a transverse bore 17 of the plug-in part 5 are aligned, which at both ends in each case a conical enlargement 18 having.

Then there are two clamping cone 19 and 20 from both sides of the bollard 4 in the conical transverse bores 16 the same so used that the clamping cone 19 . 20 already a piece in the conical extensions 16 the transverse bore 17 of the plug-in part 5 intervention.

The screw-side clamping cone 19 has a through hole 21 for a screw 22 on, while the nut-side clamping cone 20 in the described embodiment a slightly conical hexagon socket 23 for non-positive clamping of the screw 22 matching nut (not shown). The nut gets so deep in the hexagon socket 23 of the clamping cone 20 added that a hex key of conventional type (not shown) is still above the nut in the hexagon socket 23 can be plugged to hold against when the screw 22 , a polygonal head, z. B. triangular or square, has, with a corresponding special key (not shown) is tightened.

When tightening the screw 22 become the clamping cones 19 . 20 , first with play in the respective conical cross bore 16 of the bollard 4 and in the conical extensions 18 the transverse bore 17 of the plug-in part 5 sit (see 3 ), drawn inwards, by a kind of wedge effect the entire fastener 1 to pull up and at the same time the bollard 4 down to the Einbetthülse 3 to press. This process is limited by the stop of the cam 14 of the holding piece 6 on the upper wall 24 the inner circumferential groove 15 the embedment sleeve 3 , In the 3 are the clamping cones 19 . 20 through the screw 22 and mother (not shown here) tightened, the bollard 4 against the Einbetthülse 3 clamped and the elastic buffer 7 further biased.

The plug-in part 5 can u. U. when using for bollards 4 a circumferential groove 25 have as predetermined breaking point.

In the 4a to 4e are the individual steps of assembling a bollard 4 shown, in 4e the bollard 4 is shown in tilted position. With a movement of about 4-5 mm on the buffer 4 creates a tilt angle α of 5 ° to 15 ° on the bollard.

In a less preferred embodiment, which is not shown here, the insertion part can be integrally formed integrally with the respective object, such as a bollard, etc. Of course, this eliminates the previously described mechanism of the clamping cone 19 . 20 , The tightening of the object happens here, for example, on the cams 14 of the holding piece 6 acting, downward sloping part of the upper wall 24 the inner circumferential groove 15 when turning the object.
