Description

The The invention relates to a collapsible scaffold, in particular facade scaffolding, with arranged in several floors, walkable coverings, with two from each other spaced areas rest on pad bars, which is each extending between two consecutively arranged vertical supports, wherein at least two juxtaposed vertical supports each at least partially extending substantially parallel to the vertical supports railing posts attachable, which from the associated lining bolt both upwards at least up to railing height as well extends down where it can be supported on the associated vertical support and a railing post, which in such a framework to Application can get.

at known dismountable scaffolding this type are two consecutive tubular vertical support sections at its lower end or in its lower end region by a Safety catch and at its upper end or in its upper end region connected by a lining bolt, so that a rectangular, frame-shaped Structure exists. The vertical column sections are top and bottom with mutually complementary plug-in projections or Provided plug-in openings, so each frame is based on an appropriately designed frame can be attached from above or above a trained accordingly Frame can be picked up by plugging. In this way, many can Vertical frame on top of each other are arranged, wherein each vertical frame substantially over the Height of a floor extends, which is preferably about 2 m high. The shocks between two stacked vertical frame are at least substantially between the pad latch of the lower frame and the locking bar of the upper frame.

in the in general, at least the vertical support section lying on the outside of the scaffold has suitable heights Railing attachment fittings on, at which from the associated decking railing rods are attached can, to protect people working on the pavement against falling off the scaffolding.

From the DE 202 02 658 U1 A device for mounting a temporary railing of a scaffold is already known, in which by a railing rail connected railing posts can be attached to two adjacent vertical supports, so that the railing is already mounted when the associated coating is placed and entered. In this way, a railing can be mounted in advance, as the principle of the DE 196 33 092 A1 is known to secure the scaffolding erectors from falling.

The EP 0 995 860 A1 shows a generic scaffolding, in which a railing can be mounted with non-rotating post before the covering is placed in the appropriate level. The posts have hook elements and are attached by hooking the hook elements in corresponding, arranged on the scaffolding frames eyelets on this.

Problematic in the installation of such railing posts is their attachment to the vertical frame. The attachment should on the one hand simple and easy to be possible, while on the other hand the attachment of the railing posts on the vertical frame so sure must be a solution at Loading of the railing elements not afraid must become. In addition, the attachment is preferably constructed so be that a single railing post at different commercial scaffolding can be mounted.

The The object of the present invention is to provide a framework or a railing post the aforementioned genus with the following, compared to conventional embodiments to create improved properties. In the case of the invention to be provided scaffolding, which in usual Make a first scaffolding level having a second framework level, should be the second scaffolding level assigned railing posts starting from the first scaffolding level can be quickly and easily assembled and disassembled, and also the first scaffolding level assigned railing posts should start from this first scaffolding level quickly and without problems can be mounted and dismantled, without the risk of being unwanted solution the railing post under load of the railing elements consists. In particular, an attachment of the railing posts according to the invention should also on different commercial scaffolding possible be. Furthermore, elements for attachment of the railing posts additional Take over functions of the scaffolding.

to solution This object is achieved by the features according to claim 1 or claim 34 provided.

The mechanical coupling between vertical support and railing post is about a bearing element on a support element, an anti-rotation and a support in hori realized zontal direction, which advantageously leads to the fact that the assembly and disassembly is very simple, especially because it can be done without any tools, couplings, bars or wedges.

Come in addition, that by a corresponding design of the inventively provided elements for transmission of translational and rotational forces from the railing post on the vertical support can be achieved that the railing post at different commercially available scaffolding systems can be fastened, being here from scaffold system to scaffold system at the railing post at most low, in some cases at all no changes must be made.

Farther is due to the inventive design of the guardrail post and in particular by the fact that the railing post is supported below the support member on the vertical support, that reaches the railing post over the associated with him scaffolding level It also extends downwards so that it also starts from the under the scaffolding level assigned to it lying scaffold plane can be grasped or mounted or disassembled. An assembly and disassembly of its associated scaffolding level is possible anyway, since the railing post in this scaffold plane must extend so far that the attachment of railing elements or railing spars in reasonable height possible is. In this respect, therefore, the inventive railing post, if necessary together with the railing members or elements attached thereto, both from its associated scaffolding level and from the underlying scaffolding level can be easily gripped or mounted or dismounted.

Preferably, the railing posts and railing spars or elements may be mounted and dismounted as shown in the DE 196 33 092 A1 is described.

This is according to the invention from the vertical support protruding and cooperating with the support element of the railing post Bearing element designed as a covering latch. The in conventional scaffolding systems Any existing lining bars can in this case any Have shape, in particular, is a training as a hollow or U-profile possible. The support element can then in the simplest case only one horizontal surface exist, which rests on the lining bolt, so that the concrete training of the coating is not relevant. In this way it is achieved that the railing post according to the invention with different commercial scaffolding, which have mutually different lining latches, cooperate can.

The according to the invention between railing posts and vertical support acting anti-rotation can be by any force or friction Be formed connection.

Prefers It is, however, when at the railing post in the region of the support element one or two support surfaces are formed, the in the horizontal direction on at least one of the vertical support projecting Supporting abutment are. The anvil can in this case, for example, as a decking, support tab or gusset plate be formed. It is accordingly possible to Lining bar to give a double function to that effect, that on the one hand, the bearing element for the support element of the railing post and on the other hand, the support surfaces for the rotation forms.

In the case, that the padlock consists of an upwardly open U-profile, can the railing post by means of the support element also by hanging from above the lining bolt be attached. The rotation can in this case by a hooked, in the longitudinal direction realized the lining bolt extending training of the support element be. The hook-shaped, in the U-profile protruding part of the support element, which in longitudinal direction of the lining bar must be designed sufficiently long forms in this case, the anti-rotation, since by the both sides of the hook-shaped part existing U-profile leg twisting of the support member to a vertical axis impossible is done.

Especially in the embodiment described last, it is advantageous when on the outside of the scaffolding of the lining bolt one of parts of the pavement attached thereto free End region is provided and the hook-shaped support member of the railing post hung there can be. This ensures that the with the lining latch co-operating elements of decking and railing posts are not mutually exclusive hinder.

Further preferred embodiments of a U-shaped Padlock hinged Support element are the claims To take 8 to 11.

In order to the railing posts according to the invention can not be accidentally released from the vertical supports, a lift-off provided become. This lift-off is preferably on the support element and is adjustable between a secured and an unsecured position. A preferred embodiment the lift-out is described in claim 13.

alternative for hanging of the support element on the lining latch can at the railing post at least in the area the support element may be formed a forceps element which between one the vertical support at least partially enclosing Position and a vertical support releasing position movable is. A part of this pliers element can then form the support element, which on the vertical support side Bearing element can be placed, wherein the forceps element itself naturally for transmission of horizontal forces is trained.

The Pliers element can for example consist of two pliers legs, wherein the first pliers leg rigidly connected to the railing post and the second pliers legs pivotally mounted on the first pliers legs is. The pivoting movement can in particular be a parallel to the railing post extending axis take place.

Around an unintentional release of the guardrail post from the vertical support to avoid the pliers legs in a vertical support at least partially enclosing position be lockable. The corresponding locking mechanism can open be formed in any way.

Of the rigid with the railing post connected pliers legs may preferably be particularly integral molded support element for transmission from vertical loads on the projecting from the vertical support Have bearing element. In this way it is achieved that the Pliers element not only horizontally extending forces the vertical support transmits but also the biggest part the vertical forces.

Especially it is preferred if a support surface on each pliers leg Claim 3 is formed. In this case, then forms the pliers element additionally even the anti-rotation, whereby it is particularly preferred when the forceps element side support surfaces are supported on the lining bolt. In this case then takes the Padlock both the vertical forces through the support element supported thereon as well as rotational forces in the area of rotation.

According to the invention Railing post for transmission of horizontal loads below the support element in several horizontal directions on the vertical support can be supported. In this context it is preferred if below the support member and vertically spaced from this at the railing post at least one, but preferably a plurality of supporting elements are provided, the the railing post with respect to the railing spar or -element acting horizontal forces secure. This support element or these support elements can be designed in different ways.

For example Is it possible, two support elements at the railing post to be provided on the associated vertical support from opposite sides issue. It can the support elements the associated vertical support from opposite sides with at least substantially part-circular, in particular semicircular Recesses include. The open side of the part-circular recesses in this case preferably points in a direction parallel to the longitudinal direction of the railing spars or elements runs.

The provided according to the invention supporting but can also be one piece be formed. It is particularly advantageous if a helical Training the support element is selected.

The supporting can in this case the associated vertical support over a peripheral region of more than 180 ° and less than 360 °, especially about wrap around a circumference of about 270 °. The pitch of the helix should be such that the railing post in its attachment to the vertical support in a parallel to this Position is pivotable, wherein a vertical support portion during this pivotal movement in one of the helical supporting reaches entwined position. The helical configuration of the support element simplifies both assembly and disassembly, in particular but the assembly, since only the shape of the helical support element the fitter clearly no doubt how the support element for Mounting around the vertical support moved around or must be threaded around the vertical support. Come in addition, that the helical one Training of the support element be achieved by a simple deformation of the railing post can, without additional here Parts attached, in particular, must be welded, so that the economic Effort for reduce the production.

Another alternative for the support of the railing post on the vertical support below the support element is that the support element is designed as a pliers element according to one of claims 14 to 16. In this case, it is particularly preferred who is provided in the region of the support element, a forceps element according to one of claims 14 to 18. Both pliers elements can be made similar or identical in this case. The moving parts or pliers legs of both pliers elements can be operatively connected via a suitable device, so that both clamp elements can be closed and / or opened via a single actuator.

If on the outside of the scaffolding mounted in a certain section an outwardly facing console is to be, is the embodiment according to the second Alternative to claim 33 expedient.

To 1 is located on a pedestrian passage provided, cuboid base 34 with vertical supports 12 , Cross members 35 , Railing elements 13 and diagonal supports 31 a four-storey A, B, C, D exhibiting, conventional facade scaffolding. This facade scaffold points in 2 to 4 shown enlarged, telescopically stacked vertical frame 33 on, each consisting of two consecutive vertical support sections 12 ' , an upper transverse tread bar 15 and a lower, also transversely extending locking latch 29 consist.

In the trained as upwardly open U-profile pad latches 15 laterally adjacent vertical frame 33 are after 1 at the ends with in 2 and 3 indicated, hook-like projections 16 provided walkable coverings 11 hung from the top through the safety latch 29 secured against lifting. The vertically aligned, stacked and nested vertical support sections 12 ' the successive vertical frame 33 form together from bottom to top continuous vertical supports 12 ( 1 to 4 ). The joints of the individual vertical support sections 12 ' are with 46 designated.

To the vertical outriggers 12 are after 1 at a suitable height above the pads 11 by means of railing attachment fittings 30 ( 2 . 4 ) inside in a conventional manner each superposed rod-like railing spars or elements 13 ( 1 ) attached. Several diagonal supports 31 between laterally adjacent vertical supports 12 stiffen the framework. On two vertical supports 12 is after 1 each one outwardly extending console 23 attached, which is an outwardly extending surface 11 ' and a protective grid 36 wear. The consoles 23 or the covering 11 ' are by diagonal supports 37 supported.

To 2 the covering extends 11 to the outside not quite up to the vertical support there 12 There is still room for the attachment of a board 24 allow. The toe board 24 has eyelets at its ends 26 on, in the outer end of the safety bolt 29 provided retaining pins 38 are set up.

Below the padlock 15 connects a gusset plate 27 in which there is an opening 28 for connecting a diagonal support 31 ( 1 ), the padlock 15 with the associated vertical support section 12 ' ,

How very clear from the 5 to 7 shows, the padlock 15 an upwardly open U-shaped cross-section, whereby on one side a leg 15 ' is present, to which a particularly in 7 recognizable support element 19 hanged, which is perpendicular to a railing post according to the invention 14 which stretches after the 2 . 4 and 5 both below and above the padlock 15 extends. The extension goes up as far as the highest railing element is to be arranged. For attachment of railing elements 13 ' ( 2 . 3 ) has the railing post 14 to 2 to 5 Railing attachment members 39 on, for example, can be designed as that in the DE 196 33 092 A1 described and shown. The railing elements 13 ' are parallel to the lining bars 15 extending axes pivotally mounted on the railing attachment elements 39 attached so that the railing elements 13 ' not only in the use position below 90 °, but also at much smaller and larger angles relative to the railing posts 14 can be arranged as required for the preceding assembly described below.

The substantially U-shaped support element 19 extends to 2 to 7 on the side of the vertical support 12 past and then has a substantially horizontally extending support part 22 ( 7 ) and one behind the thigh 15 ' cross hook projection 20 on. One to the hook projection 20 essentially parallel leg 21 has one below the thigh 15 ' pointing bend 21 ' on the opposite side of the thigh 15 ' attacks. The leg forming the bearing element according to the invention 15 ' the coating bar 15 resting support part 22 of the support element 19 serves to transfer vertical forces between railing posts 14 and vertical support 12 , The hook projection 20 of the support element 19 ensures together with the bend 21 ' of the support element 19 in cooperation with the thigh 15 ' the coating bar 15 for the anti-rotation device according to the invention.

As the above execution takes and especially clear in 7 recognizes, is the support element 19 thus preferably designed so that it can absorb horizontal stresses in different directions in addition to the vertical loads.

On the from the support element 19 downwardly extending portion of the substantially tubular railing post 14 are in significant vertical distance vertical distance two support tabs 17 , which the associated vertical support section 12 ' with semicircular recesses 18 from opposite sides. The open side of the recesses 18 each extends in the direction of the later to be attached railing elements 13 ' , in the 2 . 3 indicated by dashed lines. In 2 and 4 are also usually on the outer vertical support sections 12 ' preferably provided inside railing attachment fittings 30 indicated, however, which are then not needed when using the railing post invention 14 is worked, unless after completion of one or more floors, the invention mounted railing elements 13 ' ( 2 . 3 ) by conventional railing elements 13 ( 1 ), which are then attached to the railing attachment fittings 30 to be mounted.

The invention arranged below the support element support tabs 17 should appropriately so strong on the vertical support section 12 ' be pressed that there in addition to the horizontal forces to be transmitted primarily also a part of the vertical loads from the railing post 14 on the vertical support section 12 ' is transmitted.

In the embodiment of the 2 to 7 lies the railing post 14 practically in the plane of the vertical frame 33 ,

The embodiment of the 8th to 16 on the other hand differs on the one hand in that the axis of the railing post 14 from the plane of the vertical frame 33 out is offset. This can be seen particularly clearly in 12 , This will make room for attaching a console 23 created as they are in 1 is shown. The transfer of the railing post 14 so it must be so large that the appropriate space is created.

Next, the embodiment according to the 8th to 16 a lifting protection 25 on, which consists of a parallel to the vertical support 12 extending, in the support element 19 pivotable and limited vertically slidably mounted pivot pin 40 with an actuating lever extending perpendicularly away from it 41 and a locking pin also extending perpendicularly away from it 42 which is in the opening 28 engages when the pivot pin 40 in the locked position. In this engages the operating lever 41 in a recess 43 ( 13 to 15 ) a backdrop 44 one, the lock pin 42 secured in the securing position. By lifting the operating lever 41 and pivoting and lowering the same in a release recess 45 the scenery 44 occurs the locking pin 42 out of the opening 41 and gives the railing post 14 free upwards, leaving it from the padlock 15 lifted and then from the vertical support section 12 ' can be solved.

Assembly and disassembly of the railing post according to the invention 14 go like this:
Before on a bottom on a surface 11 adjacent vertical frame 33 another covering is placed on top, is of the covering concerned 11 from an inventive railing post 14 first with the support tabs 17 from opposite sides to those below the upper lining bolt 15 located area of the associated vertical support 12 ' brought up until the recesses 18 the vertical support section 12 ' pick up from opposite sides, leaving the railing post 14 vertical and above clearly above the upper decking bar 15 protrudes.

Then the hook projection 20 over the thigh 15 ' led, so that the pad part 22 the upper edge of the thigh 15 ' ( 7 ) touched. Now the railing post 14 already fixed in all directions except for the top. Provided a lifting protection 25 according to the 13 to 16 is provided, is now the locking pin 42 by lifting and pivoting in the opening 27 brought into its safety position, whereupon the railing post 14 in the position after the 2 to 16 is also secured against excavation.

Now, the one end of the railing elements to be mounted 13 ' ( 2 . 3 ) so on the already mounted railing post 14 from the floor below, like that in the DE 196 33 092 A1 is described. The other end of the railing elements 13 ' is then also according to the DE 196 33 092 A1 with the other, not yet mounted railing post 14 connected by means of which then the railing element 13 ' or the railing elements 13 ' be swung into their desired position, whereupon then the second railing post 14 by means of the support tabs 17 and the support element 19 on the vertical frame 33 is attached in a similar manner, as is the case from the 5 to 7 results. Then then here can also secure the railing post 14 done as the basis of the 14 to 16 has been described.

Once the railing element 13 ' or the railing elements 13 ' have been mounted, is the associated coating 11 from the underlying surface 11 out on the appropriate pad latches 15 hung up. Now an operator can remove the coating 11 - secured by the railing elements 13 ' - climb and then the next vertical frame 33 on the top surface 11 carrying vertical frame 33 Attach.

The disassembly is in the opposite direction, ie that first the two vertical frame 33 one floor removed, then removed from the underlying floor of the overlying pavement and only then the railing posts 14 with the railing elements 13 ' be removed.

For scaffolds with a short service life, preference is given to working so that all floors of the scaffold are equipped with the railing posts according to the invention. For longer life, the material costs for the scaffolding can be reduced if the railing posts according to the invention are used only temporarily for assembly or disassembly to ensure safe assembly and disassembly of the scaffold. Here are the structure behind the leading-mounted railing elements 13 ' ( 2 . 3 ) the normal railing elements 13 at the vertical support sections 12 ' by means of the railing attachment fittings 30 ( 2 . 4 ), whereupon the railing posts 14 with the pre-assembled railing elements 13 ' one floor higher.

The degradation takes place in reverse order. In this approach, it is important that the baluster according to the invention can be installed and removed from both the lower and the upper floor. The same applies to the operation of the lift-out 25 ,

The 17 to 21 show two stacked vertical frame 33 or sections thereof, wherein the vertical frame 33 each a decking bar 15 and a safety catch 29 exhibit. The safety catch 29 used in the manner already described to a unintentional lifted lifting a lining, not shown from the lining bolt 15 to prevent.

On the vertical frame 33 or on a vertical support 12 the same is in accordance with the invention a railing post 14 ' attached. The railing post 14 ' extends substantially parallel to the vertical support 12 , In its upper end region, the railing post 14 ' two spaced railing attachment elements 39 on, over which railing spars or elements in the manner already explained with the railing post 14 ' can be coupled.

At the height of the railing post 14 ' associated lining bolt 15 is the railing post 14 ' with a as a forceps element 48 trained support member provided, which on the one hand, vertical forces from the railing post 14 ' on the vertical support 12 transmits and on the other hand by its interaction with the lining bolt 15 forms the anti-rotation device according to the invention, which pivoting the railing post 14 ' around the longitudinal axis of the vertical support 12 prevented. The exact configuration of the tong element will be described below with reference to the 22 to 30 described.

Continue according to 17 - 21 the railing post 14 ' in its lower part in a helical support element 49 above. In this case, the helical support element 49 merely by bending the lower portion of the railing post 14 ' produced.

The helical support element 49 wraps in his on the vertical support 12 coupled position the vertical support over a circumferential range of about 270 °. By this wrap on the one hand ensures that the support element 49 in his in the 17 to 21 shown position horizontal forces in all horizontal directions on the vertical support 12 can transfer without the support element 40 from the vertical support 12 can solve. On the other hand, however, this also ensures that one does not yet with the vertical support 12 coupled ge national post 14 ' in the way opposite the vertical support 12 can be pivoted, that a vertical support portion in one of the support element 49 reaches entwined position. The support element 49 So it can be the vertical support 12 be "threaded around".

22 shows that at the railing post 14 ' firmly attached pliers element 48 in cooperation with the railing post 12 and a padlock attached to it 15 , For the sake of completeness it should be noted that below the lining bolt 15 a gusset plate 27 with the padlock 15 and the vertical support 12 is connected, which serves for example for attachment of a diagonal support, not shown.

The pliers element 48 consists essentially of a first pliers leg 50 which is rigid with the railing post 14 ' is connected, and a second pliers leg 51 , which at the first pliers leg to a parallel to the railing post 12 extending axis is pivotally mounted. Along this pivot axis extends in 22 for clarity, not shown, but in the

23 to 30 shown bearing pin 52 which is parallel to the railing post 14 ' runs.

The exact structure of the pliers element 48 is the 22 to 30 to be taken, the 23 to 26 a closed and the 27 to 30 an open position of the tong element 48 represent. For the sake of clarity is - in contrast to 22 - in the

23 to 30 only the pliers element 48 with the railing post 14 ' , but not the vertical support 12 , the gusset plate 27 and the padlock 15 shown.

In particular the 22 . 24 and 28 can be seen that both the first and the second pliers legs 50 . 51 in each case a part-circular recess 53 whose radius corresponds to the radius of the vertical support 12 is adjusted so that the vertical support 12 in the closed state of the tong element 48 in these recesses 53 can be included. The pliers legs 50 . 51 thus enclose the vertical support 12 in the closed state of the forceps element 48 practically complete. Accordingly, the closed tong element 48 capable of any forces in a horizontal plane from the railing post 14 ' on the vertical support 12 transferred to.

The first, rigid with the railing post 14 ' connected pliers legs 50 points in one of the railing post 14 ' facing away from an integrally formed horizontal surface 54 on which the support element according to the invention for the transmission of vertical loads on the lining bolt 15 forms. This horizontal surface 54 is according to 22 on top of the padlock 15 on. The representation of the 22 can be seen that it is for the possibility of transfer of vertical loads by means of the horizontal surface 54 irrelevant is whether the lining bar 15 , as in 22 , is formed from a U-shaped profile or consists of any other, in particular closed profile. Due to the formation of the horizontal surface 54 Which, in contrast to the above-described embodiments of the invention has no hook elements, is thus achieved that the pliers element 48 with any lining bars 15 or other of a vertical support 12 protruding bearing elements can be coupled.

24 and 26 show that on the pliers legs 50 . 51 one support surface each 50a . 51a is formed, which in the closed position of the pliers element on the two outer, vertically extending surfaces of the lining bolt 15 ( 22 ). The support surfaces 50a . 51a form in this way an anti-rotation, which is a twisting of the railing post 14 ' around the axis of the vertical support 12 prevented.

26 shows that the pliers element 48 by means of a locking bolt 55 can be locked in its closed position. The locking pin 55 is vertically movable in a recess of the second, movable pliers limb 51 stored. Upon complete closure of the tong element 48 moves the locking pin 55 due to its gravity down and engages in a complementarily shaped recess of the first, rigid pliers leg 50 one, leaving the second pliers thigh 51 can not be pivoted into its open position. Such pivoting is only possible again when the locking pin 55 is lifted so far that he is in the first pliers leg 50 existing recess no longer touched.

31 and 32 show a further embodiment of a baluster according to the invention 14 '' with a first pliers element 48 , which in the 20 to 30 corresponds to described pliers element. In addition, however, in this embodiment, instead of the helical support element 49 a second forceps element 48 ' at the bottom of the railing post 14 ' provided, which serves horizontal loads below the as a forceps element 48 formed Support element in any horizontal directions from the railing post 14 ' on the vertical support (not shown) to transfer. The two movable pliers legs 51 . 51 ' the pliers elements 48 . 48 ' are each with one between the pliers elements 48 . 48 ' extending shaft 56 connected, with the shaft 56 rotatable in recesses of the rigid, first pliers legs 50 . 50 ' the pliers elements 48 . 48 ' is stored. Through this connection of the two movable legs 51 . 51 ' is achieved that they basically always move together, so that the railing post 14 '' for mounting on a vertical support can be easily moved up to this, whereupon a movable pliers legs 51 respectively. 51 ' closed by hand. By this closing movement is automatically the other pliers legs 51 ' respectively. 51 closed, leaving the attachment of the railing post 14 '' ultimately by means of a single closing movement of one of the two movable pliers legs 51 . 51 ' can be accomplished.

The same applies, of course, also for disassembly, in which case, if appropriate, a securing element, for example a locking bolt, may be present 55 according to 26 , must be solved.

The 33 to 35 show a further possible embodiment of the invention, which in its basic principle of the embodiment according to 6 equivalent.

In contrast to the embodiment according to 6 points the railing post 14 but not firmly attached to him support tabs 17 on. Rather, these support tabs 17 ' according to the 33 to 35 on a separate, elongated support part 57 vertically spaced from each other. The carrier part 57 is itself in the area of the supporting element 19 ' pivotally mounted, wherein the pivot axis in a horizontal plane parallel to the lining bolt 15 extends. The said pivoting movement of the carrier part 57 with the attached support tabs 17 ' is by means of an actuating element 58 triggered, which from the support element 19 ' protrudes.

For attaching the railing post 14 on a vertical support 12 becomes the support element 19 ' at the lining bar 15 hung, with the support part 57 in his in 35 is shown position. In this position are the support tabs 17 ' not on the vertical support 12 at. After this attachment process is via the actuator 58 a pivoting of the carrier part 57 causes, so that the support tabs 17 ' from two opposite sides to the vertical support 12 be moved until they rest against her. In this position, the carrier part 57 then locked by a mechanism, not shown. This locked state is in 34 shown. In the in 34 shown position, the power transmission between railing posts 14 and vertical support 12 consequently as well as with respect to the embodiment according to FIG 6 already described.

The 36 to 38 show a further embodiment of the invention, wherein in 36 an inventive railing post 14 ''' with a complete vertical frame 33 is shown. In the 37 and 38 is for reasons of clarity only the railing post 14 ''' shown.

The railing post 14 ''' has as a supporting element a horizontally extending support surface 59 on which is on a padlock 15 can be placed any shape for the transmission of vertical forces. This support surface 59 owns at her the railing post 14 ''' opposite end of a semicircular recess, in which a vertical support 12 is receivable.

At the bottom of the railing post 14 ''' is a support strap 60 attached, the shape of the support surface 59 corresponds and accordingly also for receiving a portion of the vertical support 12 suitable is.

Because the semicircular recesses of the support surface 59 and the support strap 60 point in the same direction, it must be ensured that a vertical support located in these recesses not from the support surface 59 and support strap 60 can solve. This is done by two interactively connected pivot bolt 61 . 62 achieved, with a pivot bolt 61 just below the support surface 59 and a pivot bolt 62 just above the support strap 60 is arranged. Both pivot bolt 61 . 62 are one perpendicular to the railing post 14 ''' and perpendicular to the lining bolt 15 pivoting axis pivoting.

Furthermore, both pivot bars 61 . 62 via an actuating rod 63 connected to each other over the entire length of the railing post 14 ''' extends and angled at 90 ° at the top and bottom of the railing post 14 ''' protrudes. About a vertical displacement of the actuating rod 63 Thus, a simultaneous pivotal movement of the two pivot bolt 61 . 62 to be triggered.

In the 37 shown position are the pivot bolt 61 . 62 pivoted downwards by about 45 °, so that the semicircular recesses of the support surface 59 and the support strap 60 freely accessible, which is an insertion of a vertical support 12 allows in these recesses.

In the in 38 are shown position the pivot bolt 61 . 62 pivoted upward so that they extend in a substantially horizontal position in which they move out of a vertical support 12 from the semicircular recesses of support surface 59 and support strap 60 prevent.

Particularly advantageous in the embodiment according to the 36 to 38 is the fact that the pivot bolt 61 . 62 solely due to the gravity of the actuator rod 63 always automatically move to a closed position, which means that the pivot bolt 61 . 62 only by an active lifting of the operating rod 63 can be opened against gravity. This requires the highest possible degree of security, since the automatically adjusting ground state of the pivot bolt 61 . 62 therefore always the locked position.

In principle, the railing spars or elements used in the various embodiments of the invention can be used as shown in FIG DE 202 02 658 U1 be telescopic. However, according to the invention, non-telescopic railing elements are preferably used.
