DESCRIPTION

Posts for a fall protection railing TECHNICAL AREA

The present invention relates to a post for a fall protection railing for construction sites and a fall protection railing designed as a system. 10

STATE OF THE ART

It is common practice to use rectangular tubes for posts on construction site railings. The post is placed on a screw anchor base attached to the substructure. Board elements are used as railing rods and are screwed or nailed to the post using screw units.

DESCRIPTION OF THE INVENTION

The present invention is based on the technical problem or task of specifying a post for a fall protection railing and a system for a fall protection railing that can be easily and quickly assembled or disassembled, that can be produced economically, that enables the use of series scaffolding parts, that is adjustable in inclination and that allows pipe coupling connections known from scaffolding construction.

The post according to the invention is given by the features of independent claim 1. The fall protection railing for construction sites according to the invention is given by the

Features of independent claim 6 are given. Advantageous embodiments and further developments are the subject of the dependent claims.

The post according to the invention for a fall protection railing for construction sites has the following features in combination:

- the post is designed as a round tube,

- the post has at least two longitudinal

spaced apart L-profile-shaped first connection units with an upwardly pointing leg each for the possible connection of a toe board and

- on the side of the post opposite the first connection units, at least two second connection units are connected, which are arranged at a distance from one another in the longitudinal direction and are designed as projection units for a possible connection of railing rods which can be pushed onto the projection units via recesses.

Since scaffolding is usually required on construction sites, the fall protection railing can be made of scaffolding elements thanks to the two connection units, depending on which elements are available on the construction site. These can be toe boards or telescopic railing rods, which are familiar from scaffolding construction. The telescopic nature of the railing rods ensures that the railing can be easily adapted to different inclinations and distances.

A preferred embodiment of the post according to the invention is characterized in that at the second connection

-A-

Because the railing rods are simply attached to the second connection unit, in conjunction with their telescopic nature and their ability to rotate around the second connection unit, almost any inclination can be easily achieved. The use of standard scaffolding components known from scaffolding construction as railing rods increases the economic use of such fall protection railings.

Because the posts are made of a round tube profile, base tube railing bars can also be connected using normal pipe couplings if no telescopic railing bars or toe boards are available on site.

The post according to the invention provides a component for forming a fall protection railing, on which three standard scaffolding components can optionally be used as railing bars.

Further embodiments and advantages of the invention result from the features further listed in the claims and from the exemplary embodiment given below. The features of the claims can be combined with one another in any way, provided they do not obviously exclude one another.

.WAYS OF CARRYING OUT THE INVENTION

Fig. 1 shows a section of a fall protection railing 50 of a staircase construction 52. The fall protection railing 50 has vertically arranged posts 10, which are shown in more detail in Fig. 2. The post 10 is formed by a round tube profile, which has a step-like cross-sectional taper in its foot area 26. This foot area 26 is inserted into a bearing sleeve 28 (Fig. 4). The bearing sleeve 28 is welded at the front end at right angles to a console unit 32, to the front edge of which, arranged on the left in Fig. 4, a square flange 30 is welded. The flange 30 has a

Screw recess 36 and a central bore 34. Depending on the circumstances, the flange 3 0 and thus also the bearing sleeve 28 can be connected to the staircase construction 52 via screw connections.

Pointing to the right in Fig. 2, two first connection units 12 are provided on the post 10, spaced apart from one another in the vertical direction. These are formed from an L-shaped profile, the first leg 40 of which is welded perpendicular to the axis 42 of the post 10 and which merges into a vertical leg 14 with two spaced recesses 24. Toe boards 38 can be nailed to these connection units 12 as railing rods. A toe board 38 is shown in dashed lines in Fig. 2.

In the outer side of the post 10 opposite the first connection units 12, there are two second connection units 16 which have a projection unit 18 welded vertically to the axis 42 and at the end region of which a rotatable tilting pin 22 is arranged.

The railing rod 20 shown in Fig. 3 is a series scaffolding component. It is formed by two telescopically inserted tubes. The end region 44 of the tubes is flattened and has a round recess 46, the diameter of which is slightly larger than the diameter of the projection unit 18. The railing rod 20 is connected to the post 10 in a simple manner in such a way that first the tilting pin 22 is brought into a horizontal position, then the railing rod 20 is pushed onto the projection unit 18 via the recess 46 and then the tilting pin 22 returns to the vertical position according to Fig. 2 due to its own weight, whereby the railing rod 20 is secured against being pulled off.

If no toe boards 3 8 or railing bars 20 are available on the construction site, round tubes can be connected as railing bars via pipe couplings due to the round tube cross-section of the post 10, whereby the latter structural elements also represent series scaffolding parts.

Overall, the post 10 of the fall protection railing 50 thus allows three connection options for railing bars, thus enabling a variability that significantly improves the economic use of such a fall protection railing.
