DE1894458U - SLIDING, SECURED BY A WEDGE, RAILING POST FOR JIB RACK. - Google Patents

Description

The innovation relates to a slide-out, through a wedge securable railing post for cantilever scaffolding, the foot part of which is used to guide the wedge having.

Railing posts of this type are known. In some of the known railing posts, the wedge is over a chain fixed on the railing post, so it cannot be lost.

The innovation is based on the task of providing a guardrail post that can be secured with a wedge, whose wedge is not only fixed captive on him, but is also guided so that the railing post on a boom can be pushed open without the wedge hindering the pushing on.

A railing post that fulfills this task is characterized by a shoulder and an inclined surface

existing, additional management resources that work together with the weight of the wedge strive to hold the wedge with .. ·. at least one of the upper edges or surfaces of the guide slots to be brought into contact. It is useful as a Approach to provide a dowel pin. «And fix this on the wedge, i.e. the inclined surface is at the foot of the railing post set. The approach or dowel pin remains, regardless of the position of the wedge, within of the foot part of the railing post and limits the sliding movement of the wedge. Will the wedge in the sense Firmly knocked into the foot of the handrail post, then the clear space between the inner surface of the lower part of the railing post foot and the surface of the wedge that is closest to this area low, in the other position of the wedge this clear space is much larger, so that a railing post on a boom can be pushed open without difficulty when the wedge is in the last-mentioned end position is located.

Features of the innovation that are essential to the invention are explained schematically below using an exemplary embodiment.

Pig. j5 a section along the line III .-. III of Fig. 1, different positions of the wedge are shown in dashed or dash-dotted lines.

The railing post consists of the actual Bf-os-th 1, -an the hook-shaped parts 2, j5 and 4 - as shown in Fig 1 seen -. Are set, the hook 2 is by means of a 'sleeve' 2 * relative to the flange I ¹ of the post 1 having a T-profile cross section in the exemplary embodiment.

The foot part 5 of the railing post consists essentially of two metal sheets 6 and ¹ J, one ends of which 6 ^f and 7 * are welded to the flange 1 'and to the web 1 ″ of the post 1, the distance between these two ends of the metal sheets 6 and 7 thus essentially corresponds to the thickness of the web 1 ". The distance between the other free ends 6 ″ and 7 ″ is chosen so that it is slightly greater than the thickness of the web of a double-T profile onto which the foot part 5 of the railing post is to be pushed.

As can be seen from FIGS. 1 and 2,. ends the post 1 at a distance from the ends 6 "and 7", in such a way that this The end face of the T-profile rests against a surface 8 of a transverse plate 9. T-profile and plate 9 are welded together tied together. The distance of the surface 10 of the transverse plate 9 from the inner side surfaces of the free ends 6 "and 7" is dimensioned so that the foot part of the handrail post can be pushed onto one end of a bracket with sufficient play is.

In addition to the transverse plate 9, a swash-plate 11 is fixed between the two sheets 6 and 7 are separated from each other are _Jt distance which is slightly greater than the width of a wedge 12 which is slidably guided in slots Ij5 and 14 of the plates 6 and 7. FIG. The upper surfaces or edges of the slots IJ> and 14 are denoted by 13 or l4 ^{T f.}

A dowel pin 15 is provided as the approach associated with the wedge 12. This dowel pin is when the wedge 12 has fixed the railing post opposite a double-T bracket 16, in the vicinity of the metal sheet 6 (Pig. Jj) * it is then at a distance from the top surface 11 'of the inclined plate 11, the upper one Wedge surface 12 ^T is supported on the edges or surfaces 13 'and 14', the lower surface 12 ″ sits on the upper side surface of the flange 16 ^{f of} the boom 16. If the wedge 12 is now moved in the direction?, Of the arrow 17, So influenced by the foot of the railing post in the sense of loosening, then the dowel pin 15 comes into contact with the surface 11 'and lifts the wedge 12 from the flange 16'. If the wedge 12 is in its dot-dash position, then it is over the sheet metal 7 protruding part of the wedge 12 is heavier than the other part and the surface 12 'rests on the surface or edge 14' of the slot 14. The distance between the wedge surface 12 'and the free ends 6 "and 7" of the Sheets 6 and 7 increased so that the railing post is now oh ne difficulties from the flange l6 ^{f of} the boom can be solved.

As can be seen from the drawings, after the invention trained railing post was assembled, the securing means against losing the wedge 12, namely the approach or dowel pin I5, not directly from the outside accessible, although it can still be driven into a hole provided in the wedge when the post is assembled is. However, in order to be able to loosen the dowel pin, you have to use a tool so that the wedge is practically secured against loosening, because of course the diameter of the bore provided in the wedge 12 is so dimensioned so that the dowel pin 15 can only be driven in.
