Abstract

The connector system which is positioned between spacers supporting the barriers and C-section posts (12) includes claws (9) and plate-type slide elements (22) made of weatherproof UV-resistant plastics and engaging by grooved studs (23) in bores (19) in the arms (20) of the posts . Conical transitions (26) are formed between the ring grooves (25) of the studs and the facing surfaces (27) of the slide elements so as to minimise the play between a claw and a post. The heads of the studs adjoining the ring grooves are conical.

Description

Connection arrangement between a spacer or distance piece carrying a protection fence and a pillar.

The invention relates to an arrangement of connection between a spacer or spacer piece, which it has on the front side a protection fence of a section of protective fences and a C-shaped or sigma pillar in the cross section according to the characteristics of the preamble of claim 1.

A connection arrangement of this type belongs to the state of the art in the extension of the DE document 36 40 821 C1. This document publishes all the characteristics of the preamble of claim 1. It comprises between the arms of a C-shaped jaw in cross section, connected in a way removable with a spacer piece, and the arms of the pillar in Sigma shape in the cross section surrounded by the jaw and coupled with it by means of theoretical break screws sliding elements of the type of fence of a plastic weather and UV resistant. To the elements of sliding are associated with pivots provided with grooves annular, that fit with the effect of retention in holes in the Pillar arms

In case of impact of a car on a protection fence section, the impact energy causes a comparatively soft pillar flexion. This way it force the protection fence section around its axis longitudinal and occurs at the fixation points between jaws and pillars a force directed upwards. This The theoretical breakage screws are destroyed. Through the  division of the sliding elements between the arms of the jaws and the arms of the pillars prevents friction of steel on steel, so that now the jaws can move without considerable resistance to friction in relation to pillars and can slide under the pillars. In this case, the two sections of protective fences connected by means of the distance pieces remain joined together. Do not However, the section of protection fences away from the road it is pressed down on the ground and thus supports the protection fence section directed towards the roadway through of the spacer pieces. All the provision of fences Protection can be folded as necessary. The energy of impact is eliminated as desired without recovery effect elastic and the impacting car is driven along the protection fence section on the side of the road. Market Stall that the section of protection fences directed towards the roadway, in virtue of the torsion of the provision of protection fences around its longitudinal axis, it extends now arranged more high than originally, it is excluded that a vehicle that impacts You can go through this section of protection fences.

Although the known connection arrangement has given good results in practice, there is a behavior of not always satisfactory slippage of the jaws in the case of a vehicle crash due to the necessarily present game between a gag and a pillar.

The invention - based on the state of the technique- has the problem of creating a connection layout between a spacer or spacer piece that you carry on the front side a protection fence of a fence section of protection and a C-shaped or sigma abutment in the section transverse, in which the slip behavior is improved of the jaws in case of impact between a vehicle and a section of protection fences.

The solution to this problem is the invention according to the features of the claim one.

The central idea of the invention is the configuration of conical transitions between annular grooves in the pivots and the surfaces directed towards them of the elements Sliding. Under this configuration it can be reduced at least the game between a gag and a pillar. Behavior of slipping of the jaw in the case of impact of a car over a section of protection fences is improved clearly this way.

In this context, it is advantageous that the height of the conical transitions correspond approximately to half of the width of the annular grooves (claim 2).

In addition, it is considered advantageous under the invention according to the features of the claim 3, that the ratio of the maximum diameter of the transitions with with respect to the diameter of the annular grooves it is sized approximately between 1.5 and 1.75: 1, preferably approximately with 1.65: 1.

Since according to claim 4, the pivot heads that follow the annular grooves are conically configured, it is easy to assemble the sliding elements in the arms of the pillars. The annular grooves ensure a perfect mooring of the elements of sliding on the pillars.

Also the characteristics of the claim 5, according to which the pivots are provided with notches arranged in a cross shape, they facilitate the assembly of the elements sliding on the pillars, so that the pivots are they can better insert into the holes in the arms of the pillars

With the features of claim 6 not only a reduction of the material is achieved, but that it also facilitates the insertion of the configured pivots of this flexible way in the holes of the pillar arms.

       \ newpage
    

Both mounting the elements of slippage as well as the slip behavior of  jaws can be further improved through the characteristics of claim 7.

The arrangement of elongated holes in the sliding elements and on the arms of the pillars in combination with the fact that in the arms of the jaws only one drill is planned, it is configured with a single sliding element, to configure the behavior of slipping optimally on the sides of a jaw or Well of a pillar.

In combination with the characteristics of al minus one of claims 1 to 8, the characteristics of the claim 9 advantageously provides that the fences of protection have an essentially shaped cross section of W, which is formed by a central bottom, by ribs that diverge from the bottom, by arc-shaped domes provided in the extreme side of the ribs and by arms that connect in the domes and that extend in a V-shaped direction towards the ribs, which end approximately in a plane, in which the bottom is also extended, so that on the extreme side of the arms are provided with appendages that move away from the bottom, in which extreme slats that extend are connected approximately in the direction of the arms.

Under the appendices and the slats extremes, such a protection fence has a moment of higher resistance and, specifically, in X-direction, in Y-direction as also in Z-direction. Torsion stability of the protection fence is clearly improved, so that with trouble-free compatibility with protection fences Conventional, the retention phase H1 (new assembly, repair) now also meets the high requirements of the phase of H2 retention with respect to the highest retention capacity. The possibilities of variation consist in this case in the configuration of the width of the appendages and / or the width of the extreme slats. In addition, through the degree of layering of the appendages with respect to the arms or the slats ends with respect to the appendages can still be adjusted from in a more variable way the required retention capacity of the protection fence

Another essential advantage is that through of the selective configuration of the protection fence with appendages and extreme slats maintains the ability to stacking as in the known protection fences of the phase H1 retention. this facilitates not only storage space economizer, but also transport from the warehouse to mounting locations on the roads of cars

The embodiment according to the features of claim 10 provided in combination with the characteristics of at least one of claims 1 to 8, that the protection fences have a cross section essentially in the form of W, which is formed by a central fund, by ribs that diverge from the bottom, by domes in the form of arch provided on the extreme side of the ribs and by arms that connect to the domes and extend in the opposite direction V-shaped towards the ribs, which are suspended in base sections and angled end sections in the direction of bottom, whose longitudinal edges end approximately in a flat, which touches the bottom tangentially. In this case, both the ratio of the width of the extreme sections to regarding the width of the base sections as well as the relationship of the distance between the planes that touch tangentially the rounded bottom, on the one hand, and the domes, on the other hand, with respect to the distance of the longitudinal planes that cut The domes in their auction zones is approximately 1: 2.

These features allow the same way to improve the resistance moment of the protection fences  in X-direction, in Y-direction and in Z-direction with respect to a capacity of high retention with a view to the H2 retention phase.

The following explains in detail the invention with the help of embodiments shown in the drawings. In this case:

To configure the most flexible pivots, these are provided with 28 notches arranged in a cross. The notches 28 are extend only through head 24 and annular groove 25. In addition, Figures 2 and 3 allow recognizing that the pivots 23 they are provided with holes 29 that cross the elements of slip 22.

The central axis of each pivot 23 in an element slide 22 extends in the longitudinal median plane vertical VML of the slide element 22. In the area of the surface of the sliding element 22, which is outside of the pivot 23, two elongated holes 30 are provided, which are they extend parallel to each other and are willing to it distance from the longitudinal median plane. Figure 2 shows that in the arms 20 of the pillar 12 is provided in each case an elongated hole 31 corresponding to the elongated holes 30 of the sliding elements 22 while in the arms 14 of the jaw 9 is provided in each case a drill 21 which corresponds to one of the elongated holes 30. In this way only one type of sliding element 22 is necessary to the two arms 14 of the jaw 9.

During mounting of jaw 9 on a pillar 12 the sliding elements 22 are first fixed through the pivots 23 and the holes 19 in the pillar 12. A the jaw 9 fixed in one piece is then moved spacer 4 on the pillar 12, so that the elements of sliding are placed between the arms 20 of the pillar 12 and the arms 14 of the jaw 9. Then the screws are tightened break theorists 18, which transitions are pressed conical 26 in the holes 19 of the arms 20 of the pillar 12.
