Description

The invention relates to a collapsible scaffold according to the preamble of claim 1 and handrail adapter and handrail elements according to the preamble of claim 18.

From the FR-A 27 27 454 is such a collapsible scaffold or such handrail adapter and handrail elements are known, wherein a provided without special fasteners at the end horizontally disposed tube is fastened via a screw-type device to a supported by a vertical support rosette rosette.

From the WO 97/27372 is already a collapsible scaffold with attached to vertical columns rosettes known in the openings of horizontally arranged struts are hooked by means provided at their ends hook-wedge mechanisms, the hook-wedge mechanisms cause an automatic locking with the associated Lochrosette.

The EP 0 004 179 A shows a collapsible scaffold, in which hook-shaped fastening means can be connected to the end having horizontally disposed tubes with a provided on a vertical brace clamping mechanism.

The DE 196 33 092 A1 shows a collapsible facade scaffolding, are in the handrail elements from the underlying coating to a directly attached to a vertical strut railing holding member are suspended.

The object of the invention is to provide a collapsible scaffold and balustrade adapter and railing elements of the type mentioned, which also allow the attachment of the railing elements from the underlying surface, when the fasteners at the ends of the railing elements are not suitable for this purpose.

To solve this problem, the features of the characterizing parts of claims 1 and 18 are provided.

In this way, railing elements can be hung with the mounting plate for mounting in hole escutcheons from the underlying base of inappropriate fasteners at the ends of the underlying covering on the railing holding elements of the adapter, which was previously attached to the associated Lochrosette.

Furthermore, the invention makes it possible for the sole or at least the uppermost railing element to be mounted above a covering at a distance above the associated floor covering on the associated vertical support, which is not limited by the predetermined distance between the hole rosettes. The invention thus provides a railing adapter with which a railing element can be fastened at a desired distance above a hole rosette.

The handrail adapter according to the invention thus fulfills a dual function in that it can be adapted to any handrail elements and ensures a desired distance of these handrail elements above the associated eyelet rosette.

Advantageous distances of the railing holding member from the underlying rosette escaping claim 2.

The embodiments according to claims 3 to 5 are therefore preferred because there is no need for screw connections and the connection is brought about in an extremely simple manner, in particular by wedging or tensioning of the railing adapter between an outer edge of a hole of the hole rosette and the periphery of the vertical support.

The embodiments according to claims 6 and 7 have the advantage that the above-all acting outward loads of the railing elements are particularly well transferred to the vertical supports.

The further developments according to claims 8, 9 allow in a particularly advantageous manner, to ensure a suitable distance between the railing holding member and the Lochrosette.

The installation of the handrail adapter is substantially simplified by the embodiment according to claim 10 with respect to a screw mechanism. By using a hook-wedge mechanism in particular according to the EP 0 876 541 B1 is a very simple, safe and solid, but nevertheless releasable attachment of the railing adapter to a rosette guaranteed. The handrail adapter needs to be placed in this way only from the top of the hole rosette and inserted into one of the same holes, wherein the handrail adapter fixing wedge automatically falls into the associated hole of the hole Rosette and thus fixes the handrail adapter.

The railing holding member is preferably formed according to claim 11. This embodiment of the invention makes it possible in a preferred manner, the attachment of railing elements, which are not suitable for a direct connection with a rosette. The handrail adapter according to the invention thus not only ensures the attachment of handrail elements at a desired distance above the associated hole rosette, but also gives the possibility to use any handrail holding elements, which are adapted to the mounting requirements of a desired handrail element.

A further advantageous embodiment of the invention takes the claim 12th

By the measures of claim 13, the attachment of a railing element is favored.

The embodiment according to claim 14 ensures that the railing holding element does not protrude too far beyond the outer circumference of the hole rosette.

The development according to claim 15 is used to save weight and easy handling.

A particularly compact and stable embodiment is defined by claim 16. The designed as a solid body housing is supported both vertically to the hole rosette as well as horizontally on the circumference of the vertical supports. The above-mentioned hook-wedge mechanism causes the intended for a tight fit wedging.

Due to the development according to claim 17, the handrail adapter is additionally supported at the level of the attachment of the railing holding member on the vertical support.

After the FIGS. 1 and 2 has a collapsible framework of, for example, 2 m or 3 m long, individual sections 12 ', 13' existing vertical supports 12, 13, in predetermined, preferably the same vertical distances of, for example, 0.5 m around it extending hole rosettes 14th wear.

At equal lateral intervals four pairs of two consecutive vertical supports 12, 13 are arranged, between which at certain vertical distances of e.g. 2 m pad latches 15 are mounted in associated rosettes 14. The pad bars 15 are used for hanging accessible by persons elongated, rectangular coverings 11th

Above the coverings 11, the ends of rod-shaped railing elements 16, 17 are fixed to the front side of the frame to the hole rosettes 14 adjacent vertical supports 12, which on the coverings 11th to protect working people against falling. While two railing elements 16, 17 lying one above the other provide a greater degree of safety, in principle even a single railing element 16 above each covering 11 would be sufficient to secure the persons working on the coverings 11.

At superposed Lochrosetten 14 each have a covering 11 on the pad latch 15, then a first railing element 17 and a second railing element 16 are attached. The overlying rosette hole 14 is without function.

Next, the framework on the front at certain points on diagonal supports 20, which may extend from one of the hole rosettes 14 of the vertical supports 12 to further down or above arranged hole rosettes 14 of an adjacent vertical support 12.

After the FIGS. 1 and 2 the lowest vertical support sections 12 ', 13' are formed substantially shorter than the overlying sections; they represent the basis of the scaffold and are connected by lining bars 15, which, however, do not have to bear any coating. Height-adjustable spindles 52 are provided between the bottom hole rosettes 14 and the support on the floor for the purpose of leveling unevenness in the floor. The spindles 52 are provided for the sake of clarity FIG. 1 are not shown. To stabilize the framework in the area of the lower lining bars 15 are after FIG. 1 attached above the bottom plates 51 and spindles 52 between the hole rosettes 14 adjacent vertical supports 12, 13 horizontal bar 18.

That in the FIG. 1 For example, shown facade scaffold has a non-accessible substructure F and above three due to the pads 11 walkable floors A, B and C. The floors A, B and C are closed on the right side by front side railing 19.

How one FIG. 2 can be seen, seen from below second front vertical support section 12 'is formed around two hole rosettes 14 longer than the second rear vertical support section 13', while the remaining, above it vertical support sections 12 ', 13' are all formed of equal length and respectively wear four hole rosettes 14. This training is for the inventive attachment of the railing elements 16, 17 of importance because it is thereby possible to bring from an already created covering 11 from a front vertical support 12 'by attaching to the already completed part of the vertical support 12 in such an altitude that at one of the top hole rosette 14 according to the FIGS. 3 to 6 provided handrail adapter 21 from below a railing element 16 can be mounted.

Since no handrail elements are required in the rear vertical supports 13 in the application shown or can also be introduced later, the rear vertical support sections 13 'each end immediately above a lining bolt 15, while the front vertical support sections 12' in each case by two rosette intervals above extend each pad latch 15.

After the FIGS. 3 to 6 have the hole rosettes 14 relative to the vertical support axis 27 at an angular distance of 90 ° four relatively large profiled holes 23 and between relatively small circular holes 28 on.

The large holes 23 are used to secure the lining bars 15 and the guardrails 16, 17 by means of a handrail adapter 21 according to the invention, while the small holes 28 are e.g. can be used for holding the ends of the diagonal supports 20.

While after that in the FIGS. 1 and 2 the prior art, the ends of the railing elements 16, 17 are hooked by means of suitably trained hooks directly into the holes 23 of the associated Lochrosetten 14 is according to the FIGS. 3 to 6 According to the invention in a hole 23 on the inside of the outer vertical supports 12 in the FIGS. 7 to 10 in detail shown handrail adapter 21 mounted, which from a bottom to top obliquely to the vertical support 12 extending flat profile 25, a hook wedge mechanism 26 arranged thereon with a trained as a solid body 37 and a top substantially vertically from the flat profile 25 inside consists of extending railing holding member 22, on which according to the DE 196 33 092 A1 a railing element 16 having a suspension opening 30 is attached to each end, as shown in FIG FIG. 5 and 6 indicated by dashed lines.

The flat profile 25 has at the top a vertical support 12 directed towards the bend 29, which has on the vertical support 12 side facing one of the outer contour of the vertical support 12 corresponding support surface 24 which rests in the assembled state on the periphery of the vertical support 12. Below is the flat profile 25 with an inwardly facing Abstützabwinklung 31 provided which rests in the assembled state on the top of the hole rosette 14.

The wedge mechanism 26 consists of a hinged in the associated hole 23 wedge hook 32 and a displaceable in a groove 33 of the same wedge 34, which according to the EP 0 876 541 B1 are trained and work. On the wedge 34, an inwardly facing projection 35 is provided, which prevents the unmounted state of the handrail adapter 35 from falling out of the wedge 34 and allows mounting of the handrail adapter 21, a subsequent hard beating of the wedge 34. By said beating the wedge 34 can ultimately be taken so far that it rests on the top of Abstützabwinklung 31.

The housing 37 of the hook wedge mechanism 26 is supported on both sides via support projections 36 on top of the hole rosette 14 and rear over upper and lower support surfaces 39 on the vertical support 12.

The function of the handrail adapter 21 according to the invention is as follows:

The railing adapter 21 is placed at the desired location from above on the hole rosette 14, wherein the wedge hook 32 penetrates into the opening 23, the wedge 34 but is supported with its lower end on the top of the hole rosette 14 outside of the hole 23 and thereby in the Groove 33 is moved relative to the wedge hook 32 upwards.

Once the wedge hook 32 has been inserted so far into the hole 23 that the Abstützabwinklung 31 and the Abstützvorsprünge 36 on the Top of the hole rosette 14 rest. Shortly before, the lower end of the wedge 34 reaches into the region of the hole 23, so that the wedge 34 by hard impact and / or by gravity in the in the FIGS. 3 to 6 shown mounting position can be moved down, where it is keyed with the hole rosette 14, wherein the projection 35 can rest on the Abstützabwinklung 31. The railing adapter 21 is now according to the EP 876 541 B1 attached to the vertical support 12, and it may be a railing element 16 according to the method of the DE 196 33 092 A1 be attached to the railing support member 22 until it the in FIG. 5 . 6 indicated by dashed lines position. The handrail adapter 21 according to the invention is thus first attached to the hole rosette 14 and the associated vertical support 12 (or 13) and thus to an integral part of the vertical support. Only then, as in a vertical support equipped directly with the railing holding element 22, is the railing element 16 attached to the railing holding element 22. The handrail adapter 21 according to the invention is therefore attached to the hole rosette 14 independently of the handrail element 16.
