Description

The invention relates to a railing for accident prevention, in particular in the area of stair flanks, floor flanks of buildings or the like, whereby in order to achieve a secure hold even in the case that at least parts of the railing are only to be provided provisionally during construction work or as a makeshift railing, according to the invention at least one fastening device for securing the position of at least one railing component is proposed.

The invention further relates to a railing with railing components, which have at least one railing post, which for its structural fastening has a fastening device designed as a tensioning device with a tensioning member that can be moved relative to the post body.

During construction work or until completion, safety measures must be installed on buildings to prevent accidents. For this purpose, it is advisable to install a temporary railing in the area of stair flanks, freely projecting floors, balcony slabs, etc. and to make it removable. This can be done as soon as the railing intended for the finished building is in place. which can be secured or no separate security

no longer required, can be removed again.

The invention is also based on the object of creating a railing of the type mentioned, which prevents the tiling of known solutions and, in particular, enables easy-to-handle positional security even when the design is removable.

To solve this problem, in a railing of the type described, means are provided according to the invention to be able to clamp the railing post or posts in their installation position using an adjusting device in such a way that the clamping moment can be determined relatively sensitively and precisely, in contrast to, for example, a clamping force driven in by hammer blows. If the adjusting device is permanently mounted as an essential whole on the railing post, all parts of the clamping device are designed to be captive. Furthermore, the use of an adjusting device makes it possible to provide the actuating element relatively far away from the actual clamping area of the railing post or at a location where it is particularly easily accessible for actuation. This location can be on the side of the railing post facing away from the clamping area and/or offset in height relative to the clamping area and takes up the same position relative to the railing post or the post body in practically every actuating position.

The design according to the invention also allows the actuating member to be designed in such a way that it can be operated by turning, so that the tightening torque of the clamping device can be precisely determined, for example with a torque wrench. If the actuating forces are to be significantly lower than the clamping forces, a reduction drive can be provided between the actuating member and the clamping member, which can be formed, for example, by a spindle drive and/or a steering drive and/or a crank reduction or the like, and can be designed in one or more stages.

The design according to the invention is suitable for external clamping, in which, for example, the railing post has a type of clamp, the clamp arms of which are brought closer together for clamping and can thus be clamped, for example, from above and below against a staircase or from both sides against the side surfaces of a wall.

However, a particularly advantageous further development also arises if the clamping device is designed for internal clamping instead or in addition to this, so that it can be clamped against the inner surfaces of an opening in the building, for example, in the manner of an at least partially expandable inner collet. The collet can form a tenon-like continuation of the lower end of the railing post or, depending on the building's requirements, protrude transversely from the railing post in the manner of an angle leg.

In order to be able to carry out work on the structure without hindrance, which extends laterally beyond a building boundary assigned to or opposite the respective railing post, it is particularly advantageous if means are provided that enable the railing post to be arranged at an appropriate distance from this building boundary. This means that this work can be carried out without prior removal.

the temporary railing. For example, when building a staircase, treads often have to be laid at the end, which extend beyond the corresponding boundary of the stair body, made of concrete for example, which was made before the railing was installed. In particular, if the fastening device for internal tensioning is designed in such a way that the temporary railing has no components that hang over the area of the treads of the steps, the respective railing post can be arranged using these means at a distance of 1 m from the corresponding side boundary of the tread of the respective stair step, which is in a vertical plane, so that no components of the railing hang over the area boundary in this plane, but there is free space for the attachment of structural parts. It is particularly advantageous if the distance is between about 40 and 100 mm, preferably at least about 70 mm.

A particularly advantageous development of the subject matter of the invention is that the clamping device and/or the adjusting device is essentially enclosed within the at least partially open side post, which thus forms a housing with its wall for the slotted accommodation of the corresponding parts. The guide of the adjustable clamping device relative to the post body can also be essentially protected within the post body, for example by providing a telescopic guide, of which the telescopic outer part is expediently formed by the tubular post body.

The object underlying the invention can be achieved in a railing of the described or another type in an advantageous manner by at least one clamping surface of at least one clamping rail in at least

a movement independent of the clamping movement, so that, for example, the inclinations of two clamping surfaces facing each other or away from each other can be mutually changed to adapt to correspondingly inclined surfaces of the structure.

In order to ensure that the clamping surfaces of the fastening device of a railing post are positioned with as little play as possible even in the presence of relatively large unevenness, means are advantageously provided which ensure that the clamping surfaces are adapted to such unevenness or similar without play by means of smaller clamping surfaces in the respective entire clamping field and/or by means of slightly elastic flexibility of these clamping surfaces. For example, each clamping surface can be formed by two clamping surface areas lying parallel to one another and at approximately right angles to the railing post. Individual clamping surface areas can also be resiliently changed in position relative to one another and/or relative to the railing post within narrow limits and under very high spring force. In a preferred embodiment, the clamping surface areas of the respective clamping arm are pre-formed on the edges of a profile that deviates from the flat shape by ¹ m in cross-section or are formed by this, with the profile being expediently approximately rectangular to obtuse-angled V-shaped with profile legs of equal length. If clamping surface areas are provided on both opposing clamping arms at a distance of 1 m from each other, these can have different or equal distances from each other on both clamping arms and in particular can be arranged so that two clamping surface areas are directly opposite each other in the direction of the clamping force. The slightly resilient V-profile ensures a very steadily increasing spring characteristic.

Another useful embodiment of the subject matter of the invention consists in the fact that the respective clamping arm with its inner end facing away from the free end is fastened to an end surface of a rod-shaped component of the railing post, e.g. the telescopic outer tube or the telescopic inner tube, in such a way that its inner end surface is essentially flush with the outside of this component facing away from its free end and is, in a closed view, continuously straight over its length. The end surface of the rod-shaped component ^is advantageously profiled in accordance with the engagement surface of the profile, e.g. V-shaped, so that a full-surface system is obtained, which, however, does not have to extend over the entire profile height of the profile arm, in particular if its clamping surface areas |, have a lateral distance from one another that is greater than

the corresponding external width of the rod-shaped component of the :■ railing post 1st. In the case of fastening the profile

If the arm is to be fixed to the railing post, means are provided to ensure that the recessed corner between this arm and the railing post is completely free of components, such as stiffening struts, at least on the top of the arm or over its entire circumference. In the case of external tensioning, such struts on the upper tensioning arm can lead to accident hazards due to people tripping, while in the case of internal tensioning, they should protrude beyond the corresponding outside of the railing post by a maximum of nsr that corresponds to the distance dimension described so that the tensioning pin can penetrate unhindered deep enough into the structure.

A 25 404 : :: : ·: · &igr; 7·.-.·

can be sunk. In order to avoid the need for such stiffening elements, the clamping arm is designed, for example, as a profile arm, to be so rigid that it does not give way, or only gives way insignificantly, under the loads that occur during clamping.

Furthermore, the object underlying the invention can be achieved in an advantageous manner in the case of a railing of the type described or of another type in that at least one counter-member, separate from the railing or the railing post, is provided for receiving the fastening device, which can be fixed, for example, by setting it in concrete at the corresponding point on the structure before the railing is attached. This counter-member can be designed in such a way that it is suitable both for receiving the temporary railing and, after its removal, for attaching the railing or the like that is to be permanently attached to the structure.

The counter-member is, particularly in the case of internal clamping, suitably designed as a receiving sleeve made of steel, plastic or a similarly suitable material. This sleeve has connection surfaces, such as welding surfaces, on the inside and/or on its outer end, e.g. on a flange plate connected to it and protruding beyond its outer circumference, for a rigid connection to a railing post. At least some of these connection surfaces, which are suitably formed by inner surfaces of the sleeve casing, are optionally also designed for a detachable connection to the railing post , preferably as essentially flat or essentially straight clamping surfaces that are uninterrupted in the longitudinal section through the sleeve.

In order for the railing feet to be precisely adjusted, particularly laterally in relation to the structure, and then secured in any adjustment position without play, it is advantageous if the connection between the

A25 494

The connection between the auxiliary railing post and the receiving sleeve is exclusively force-fit. The sleeve casing of the receiving sleeve is advantageously free of openings essentially over its length or over its circumference, so that continuous clamping surfaces are created almost over the entire length of the sleeve casing. Instead of this or in addition to this, a sealing cover made of another suitable material, e.g. plastic, can be attached to the inner end of the sleeve casing, which is formed, for example, by a pipe section, so that the penetration of concrete into the sleeve casing can be completely excluded. This cover can be attached and secured in position in a particularly simple manner using a plug connection parallel to the sleeve casing, whereby the cover can be plugged onto the outer circumference of the sleeve casing or inserted into it in such a way that the cover does not protrude beyond the outer circumference of the sleeve casing.

According to the invention, in a railing of the described or another type, at least one railing rod, such as a handrail, is further proposed, which is formed by at least one, in particular length-adjustable, profile made of metal or the like and can be adapted in length to the respective installation conditions, e.g. in the manner of a telescopic rod.

For this railing rod, a fastening device is advantageously provided which is suitable as a tensioning device, for example, for securing the railing rod in position relative to the railing post or posts without play, but detachably. The individual components of this tensioning device are also advantageously arranged in a captive manner on at least one of the parts to be connected to one another, with a movable tensioning member being provided on the railing post in particular.

A 25 404 &Ggr;&ngr;.&udigr;":- ·: ·": ·::·:":

For many applications it is advantageous if at least one bracket is provided on the respective railing post instead of or in addition to the described fastening device for the railing rod, which bracket forms at least one bow-shaped support handle, a longitudinal plug-in receptacle for a strip profile free of perforations or the like. The railing post expediently has at least one bracket on its outer side, which faces away from its tension arm or its tensioning brackets, which is fastened to this outer side by welding or the like with the ends of its superimposed bracket legs. If a bracket is provided immediately adjacent to the upper end and a bracket is provided immediately adjacent to the top of the fastening device for the structural fastening, barriers can be held both at a relatively high height and close to the ground or floor level simply by pushing them into adjacent railing posts. The fastening device for fastening the structure and the fastening device for the railing bars are conveniently located on the same, inner outside of the railing post.

According to the invention, a detachable connection is also proposed between the ends of railing rods facing each other, which are connected to one another in the longitudinal direction either in alignment with one another or, for example, offset from one another at an angle. This connection is expediently designed in such a way that the adjoining railing rods can be connected to one another both in alignment and in at least one angular position, whereby the connection expediently enables a continuous angle adjustment in the manner of a hinge connection. This makes it possible, for example, to create railings with railing rods that have railing rods that run at an angle in accordance with the course of staircase sections and intermediate landings.

The railing 1 according to Figure 1 can be assembled, for example, from a multi-part kit that has a plurality of approximately identical railing posts 2 and railing rods 3, which can be detachably attached to the railing posts 2 after they have been installed on the building. For attachment to the building, each railing post 2 has, for example, a fastening device 4 that is preferably vertically tensioned in the area of its lower end, while a fastening device 5 is provided for attaching the railing rod 3 to the respective railing post 2.

The respective railing post 2 has a hollow post body 6 which extends over most of its length or height and essentially up to its upper end and is expediently formed by a section of a profile tube, such as a square tube. In the area of the lower end, a telescopic guide 7 is provided on the post body 6 which is parallel to it, the outer tube of which is formed by the lower end section of the post body 6 and the telescopic inner rod 8 of which protrudes from the lower end of the post body 6. The inner rod 8 is expediently also formed by a profile tube whose cross sections have the same basic shape as the outer tube.

The fastening device 4 is essentially designed as a clamp 9, which can be closed or opened over its entire travel with the help of a single actuating element 11 using an adjusting device 10 located essentially inside the post body 6 or the telescopic guide 7. The adjusting device 10 has a threaded spindle 12 that projects essentially freely downwards from the upper end of the post body 6 and is located on the axis of the post body 6, which engages a spindle nut 13 attached to the upper end of the inner rod 8 in such a way that part of its length lies inside the inner rod 8. The upper end of the spindle 12 is connected to a spindle nut 13 located inside the upper

The axial bearing 14 located at the end of the post body 6 is mounted so that the spindle 12 including the actuating member 11 is secured axially in both opposite directions relative to the post body 6. For this purpose, a bearing bush 15 is inserted into an upper end plate of the post body 6, which rests with an upper annular collar on the top of the end plate and whose lower end face is opposite a bearing ring 16 or a similar axial securing member attached to the outer circumference of the spindle 12. The upper end of the spindle 12 passes into the actuating member 11 with an enlarged cross section, which rests with its associated end face axially secured on the collar of the bearing bush 15. The actuating member 11 is formed in the embodiment shown by an external hexagon located on the axis of the spindle 12.

The clamp 9 has a lower clamping member 17 that can be moved in the clamping direction relative to the post body 6, as well as a clamping jaw 18 located above it, which is arranged in a fixed position relative to the post body 6. The clamp 9 is used for clamping against the lower and upper sides of a structural part 19 indicated by a dot-dash line, which can be formed by a staircase, a floor slab or the like, for example. The spindle drive forms a reduction drive 20 when clamping and releasing, so that high clamping forces can be applied effortlessly.

To form the tensioning member 17, a cross arm 21 is attached to an outside of the inner rod 8 in the area of the lower end in such a way that it is essentially symmetrical to the center plane of this outside and at right angles to the post body 6. The cross arm 21 is expediently formed by a pipe section with rectangular cross sections, the larger edge length of which is approximately parallel to the post body 6 and the side surfaces of which are approximately aligned with the corresponding side surfaces of the inner rod 8. To form the tensioning member 17,

jaw 18, a plate-shaped cross leg 22 is attached to the same outside, but to the post body 6, at a small distance above its lower end, the width of which is expediently much larger than that of the cross arm 21 or the outside width of the post body 6, so that the cross leg 22 protrudes laterally on both sides beyond the post body 6. The cross leg 22 can be formed by an angle leg of an angle plate, which is attached with its other, upwardly projecting angle leg to the

and whose legs are braced against each other. The surface of the cross leg 22 facing the tendon 17 forms the associated, essentially flat tensioning surface 24, which can also protrude over the tendon 17 in the longitudinal direction of the cross leg 22, so that it forms a type of standing surface that ensures that the railing post 2 stands securely on the structural part 19, e.g. for the purpose of alignment, even when the tension clamp 9 is not closed.

The clamping surface 23 of the clamping member 17 has a significantly smaller total area than the clamping surface 24 and 1st

The bearing axes of the pressure pieces 25 are expediently parallel or aligned with each other and at right angles to the post body 6 or parallel to the cross arm 21 in an axial plane of the post body 6 or the cross arm. The fork-shaped bearings 26 are attached to the top of the cross arm 21 and each have two bearing cheeks on either side of the associated pressure piece 25, with one bearing cheek of a bearing 26 simultaneously forming an outer

* ^# In the embodiment according to Fig. 2, the fastening device 4a is designed in the manner of a mandrel 9a for internal clamping in such a way that the clamping surfaces 23a, 24a are moved away from each other during clamping. For this purpose, a single, housing-like hollow cross arm 21a is fastened in the area of the lower end of the post body 6a, which

serves as a plug-in pin for insertion into a hollow counter-member 18a adapted to it. This counter-member 18a is to be fastened to the structural part 19a, e.g. by embedding, and consists essentially of a pipe section 22a of larger but approximately the same cross-section as the mandrel 9a, as well as a flange plate 28 fastened to the outer end and a closure cover 29 made of plastic or the like fastened to the inner end, e.g. by plugging. The counter-member 18a is expediently embedded in the structural part 19a in such a way that the flange plate 28 is flush with an upright edge surface of the structural part 19a. Through-holes for nails or the like are expediently provided in the flange plate 28, with which the counter-member 18a can be fastened to the inside of the formwork £ used to produce the structural part 19a. I

The tensioning member 17a, which is essentially suspended within the cross arm 21a, is expediently designed in the manner of a two-armed lever, the arm of which, closer to the free end of the cross arm 21a, projects slightly upwards over the outer or upper side of the cross arm ^21a with a region formed by a lever's longitudinal side, and with this region forms the convexly curved tensioning surface 23a. This region of the tensioning member 17a, which extends approximately over the entire corresponding inner width of the cross arm 21a, projects through a window opening 31, which is provided in the upper wall of the cross arm 21a and closely adjacent to its free end, which is closed with an end plate.

The tension member 17a is connected to the spindle drive located inside the post body 6a via a link drive 30, which is located essentially inside the cross arm 21a. The spindle nut 13a carries a bearing fork 32 at a distance below the spindle 12a, with which one end of a two-armed rod, which extends approximately in the longitudinal direction of the cross arm 21a, is connected.

extending guide bar 33. The articulated connection is made by a hinge pin 34 engaging in at least one slot. Approximately halfway between its ends, the guide bar 33 is pivotally mounted within the cross arm 21a with a bearing 35 on the cross arm 21a. The arm of the guide bar facing away from the post body 6a is articulated to the arm of the clamping member 17a facing away from the clamping surface 23a, whereby this joint is also formed by hinge pins 36 engaging in at least one slot. This arm of the clamping member 17a is expediently designed as a joint fork, between the fork cheeks of which the guide bar 33 engages. The tendon 17a is mounted on the cross arm 21a with a bearing bolt 7a passing through it. All bearing and joint axes are essentially parallel to one another and at right angles to the common center plane of the post body 6a and the cross arm 21a.

If the actuating member 11a is rotated so that the spindle nut 13a moves downwards, the clamping surface 23a is retracted into the cross arm 21a. When the spindle nut 13a moves upwards, the clamping surface 23a rests against the upper inner surface of the counter member 18a, while the lower outer side of the cross arm 21a facing away from it forms the second clamping surface 24a, which clamps against the lower inner surface of the counter member 18a. The link drive 30 can be designed in such a way that it also forms a reduction drive, so that a two-stage reduction drive is provided between the actuating member 11a and the clamping member 17a.

The fastening device 4a is designed in such a way that between the inner outer surface 27a of the railing post 2a and the opposite surface of the structural part 19a or the outer end of the counter member 18a or the flange plate 28 within relatively large limits

a distance can be set continuously, which is appropriately in the order of 70 mm. This means that even when the railing post 2a is mounted in a fixed position, work in the area of the tread of the structural plate 19a that extends laterally beyond this structural part 19a is not hindered. The recessed angle between the inner outer surface of the railing post 2a and the upper longitudinal surface of the clamping mandrel 9a is free of struts or the like, so that a gap that extends to the open side of the structural part 19a remains free between the tread surface of the structural part 19a and the outer surface 27s.

After loosening and removing the railing post 2a, the counter-member 1bd remains on the structure so that it is suitable for attaching the railing post of a final railing to it, e.g. by casting or also detachably. Otherwise, in Figs. 1 to 4 and 7, 8, the same reference numbers are used for corresponding parts, but with different letter indices, which is why the corresponding description points apply to all figures.

The fastening device 4b according to Fig. 3 is also designed for internal clamping essentially as a mandrel in the manner of an internal collet 9b. For this purpose, the cross arm 21b is slotted lengthwise on both opposite sides, so that two U-shaped collet arms 25b are formed, which project freely over most of its length and are each U-shaped in cross section, which lie one above the other and form clamping surfaces 23b with the outer sides of their U-shaped cross legs facing away from one another. A wedge piece is fastened in each of these clamping arms 25b in such a way that the clamping surfaces facing one another diverge in the direction of the free end of the cross arm 21b. An internally positioned clamping wedge 8b with corresponding clamping surfaces is guided on the clamping surfaces 7b. The clamping beam 8b has a 1m essential 1n of the

The spindle 12b has an internal thread 13b located on the central axis of the cross arm 21b, into which the spindle 12b is screwed. The spindle 12b, which is parallel or coaxial to the cross arm 21b, lies with most of its length inside the cross arm 21b and passes transversely through the lower end of the post body 6b in such a way that it is guided to the outside facing away from the cross arm 21b and carries the actuating element 11b on this outside. The cross arm 21b can be spread out and then narrowed again by springing back, with the cross arm 21b being suitably assigned to a hinge similar to that shown in Fig. 2.

In the embodiment according to Fig. 4, the clamping direction of the fastening device 4c or the clamping clamp is horizontal or at right angles to the post body 6c, the lower end of which directly forms a clamping jaw 18c in such a way that the outer surface of the post body 5c facing the other clamping member 17c is provided as the clamping surface 24c. Above the clamping surface 24c, a telescopic guide 7c protrudes over the corresponding outer side of the post body 6c, the outer tube of which is fixedly attached to the post body 6c. The telescopic inner rod 8c carries the corresponding clamping member 17c lying at an angle to it, which is provided in the area of its free end with a clamping surface 23c protruding over its inner side. The adjusting device 10c is similar to the adjusting device 10b according to Fig. 3 at right angles to the post body 6c, and the actuating element 11c is provided on the outside of the post body 6c facing away from the movable tensioning element 17c. This railing gate 2c is used in particular for fastening to the top of upright walls, such as retaining walls or the like, which can occur in road construction, for example.

According to Figures 1, 2 and 5 to 6, the respective railing bar 3 is suitably composed of two or three telescopically sliding metal profiles 37, 38, 39, which are approximately rectangular C-shaped in cross section. Each metal profile has a row of long, round plug holes 41 on the profile crossbar, which is symmetrical to its associated center plane and extends essentially over its entire length, the longitudinal extension of which is at right angles to the metal profile and which have approximately the same distances from one another and from all metal profiles 37, 38, 39, so that the plug holes of metal profiles which are inserted into one another can essentially be congruent. It is also conceivable to choose slightly different hole spacings in the individual metal profiles, in order to enable a finer adjustment than the hole spacing in the sense that the plug holes are congruent with each other in each adjustment stage.

The plug holes 41 are adapted to the corner pins 40 of the railing posts 2. Each railing post 2 or its post body 6 has two or more such plug pins 40 on the side on which the fastening device protrudes, one above the other at a distance, each at the height at which a railing rod is to be attached. The respective plug pin 40, which is elongatedly rectangular in cross section and which can also be pivoted about an axis approximately at a right angle to the railing post 2 in order to adapt to any inclined positions of the railing rod, is part of the associated fastening device 5. It serves to accommodate a flat clamping wedge 42 which passes through it at its flat side and passes through a wedge opening 43 of the plug pin 40. This clamping wedge 42, which is approximately parallel to the railing rod in the assembly position, is supported by a slanted wedge surface formed by a narrow edge on the edge of the wedge opening 43 facing away from the railing post 2 and has a

of the profile cross-piece of the associated metal profile has a keel surface formed by an edge surface, which lies essentially entirely on the inside of the cross-piece.

At its tapered end, the clamping bracket 42 is provided with a securing member 44 which is wider than the bracket opening 43 and is formed, for example, by a ball head, and which secures the clamping bracket 42 against being completely removed from the plug pin 40. When the securing member 44 is in place on the corresponding surface of the plug pin 40, the clamping bracket 42 can be aligned approximately parallel to the plug pin 40 by pivoting. The dimensions are designed so that the clamping bracket with the plug pin 40 can then be inserted into or pulled out of a plug opening 41. The plug pin 40 and the clamping bracket 42 and thus the entire fastening device 5 are essentially completely contained within the railing rod 3 or the corresponding metal profile in the clamped state.

If two or more metal profiles are inserted into one another in the area of the respective railing post 2, the plug pin 40 passes through plug holes 41 of all metal profiles, whereby these are secured or locked against one another in the longitudinal direction of the railing rod 3. In this respect, the fastening device 5 simultaneously forms a locking mechanism for the metal profiles 37, 38, 39 against one another. It is also conceivable to secure the metal profiles against one another using separate securing elements, such as bolts, which are located at a distance from the respective railing post 2 and which then pass through congruent plug holes 41. The fastening device 5 clamps the outside of the crossbar of the largest metal profile 37 directly against the corresponding, flat outside of the railing post 2.

To connect sections of the railing rod 3 which are to be connected to one another at an angle in the side view according to Fig. 5 and/or in the top view according to Fig. 6, an angle connection 45 is expediently provided, which can be designed as an adjustable joint connection. In the example shown, the angle connection 45 is provided to connect the sections of the railing rod 3 in such a way that they are either aligned in the side view or at an angle to one another within predetermined limits, whereby the sections can be angle-adjusted from the aligned position in both opposite directions.

For this purpose, at least one connecting plate 46 is attached to the end of the smallest or innermost metal profile 39 of a section of the railing bar 3, whereby a connecting plate 46 is expediently attached in a rigid position to the inside and outside of the profile crossbar in such a way that the two connecting plates 46, which are essentially congruent and parallel to one another at a small distance, protrude freely over the end of this metal profile 39. The connecting plates 46 engage the end of a corresponding metal profile 39 of the other railing bar section and are connected to it via a joint 47, the joint axis of which is essentially at right angles to the longitudinal direction of the railing bar 3 and approximately horizontal in the longitudinal center plane of the associated railing bar section.

In the example shown, the two connecting plates 46 are attached in the area of the joint 47 to the inside and outside of the profile crossbar of the associated metal profile in the manner of clamping claws. Both connecting plates 46 and the associated profile crossbar are penetrated by two bolts 49, which are spaced apart from one another transversely to the longitudinal center plane of the associated metal profile 39. These bolts 49 penetrate the connecting plates

46 or in the profile crossbar, elongated holes 48 which extend essentially around the joint axis mentioned or, approximating such a position, are at an acute angle to one another, whereby the bolts 49 engage in the elongated holes 48 with the appropriate transverse play. By tightening the bolts 49, which can be formed, for example, by screw bolts with nuts, the joint 47 is fixed in the set position. By loosening the bolts 49, the angle connection 45 can also be released. Furthermore, it is conceivable to provide joints 47 in the area of both adjoining metal profiles 39. Due to the design described, the angle connection 45 can be located essentially completely within the adjoining metal profiles 39.

At least the two larger metal profiles 37, 38 can %■
'■ ^: each have a length of about 2 m, while the smallest

Metal profile 39, on the other hand, is preferably shorter. The metal profiles 37, 38, 39 are preferably made of aluminum.

Plastic profiles are also conceivable.

In the embodiment according to Fig. 7 and 8, each clamping arm 17d, 18d is formed by a V-profile 21d or 22d, \ which is conveniently achieved by bending a sheet metal

Both sheet metal profiles can be

be designed and are each attached to the post body 2d in the manner of a free arm that extends over its entire length. The upper clamping arm 18d is attached to the lower end surface of the post body 6d or the telescopic outer tube by welding so that it reaches to its outer surface. The lower clamping arm 17d is similarly attached to the lower end surface of the telescopic inner rod 8d. The upper clamping arm 18d is free of additional stiffening struts, as shown in Fig. 1, for example, in this case, so that it has a slightly greater bending elasticity than the lower clamping arm 17d. This lower clamping arm 17d is provided with an additional

chen, angular stiffener, which is fastened by welding with a shorter leg to the outer surface of the telescopic inner rod 8d and with a longer angle leg ¹ to the underside of the clamping arm 17d facing away from the associated clamping surface 23d and is web-shaped and narrower than both the inner rod 8d and the clamping arm 17d.

The lower end surface of the post body 6d is provided with a V-shaped groove adapted to the profile of the clamping arm 18d, so that the respective profile leg of the clamping arm 18d in cross-section connects to the corresponding outer surface of the post body 6d at an obtuse angle and protrudes laterally beyond this outer surface. The corresponding end of the clamping arm 18d is provided with a through-opening adapted to the inner cross-section of the post body 6d, through which the inner rod 8d passes. The lower end of this inner rod 8d is adapted by a V-shaped tapering to the inner cross-section of the clamping arm 17d, which extends to the outer surface of the inner rod 8d or to the corresponding leg of the stiffening angle 52 and whose profile legs also protrude laterally on both sides beyond the inner rod 8d.

The profile legs of the two clamping arms 17d, 18d are directed towards each other and form clamping surface areas 23d, 24d with one edge of each edge surface. The clamping surface areas 23d, 24d of each clamping arm 17d and 18d lie parallel to each other at a distance from each other that is greater than the thickness of the railing post 2d, whereby, however, two clamping surface areas 23d, 24d are congruently opposite each other in a direction parallel to the longitudinal direction of the railing post 2s. This results in a very precisely defined position of the clamping arms 17d, 18d on the corresponding surfaces of the structural part 19d.

As Fig. 7 and 8 further show, a holder 50 is provided on the outer side of the post body 6d of the railing post 2d, which holder is formed, for example, by three identical brackets 51 lying one above the other at equal distances, which are narrower than the corresponding outer side of the post body 6d. Each bracket 51 is fastened by welding with the end faces of its bracket legs to the aforementioned outer side of the post body 6d, with the upper bracket leg of the uppermost bracket 51 expediently adjoining directly to the upper end of the post body 6d and the lower bracket leg of the lowest bracket 51 lying closely adjacent to the lower end face of this post body 6d. Each bracket Sl delimits in the side view according to Fig. 7 with the post body 6d a flat rectangular bracket or passage opening, the larger cross-sectional extent of which lies in the vertical direction of the railing post 2d and the cross-sectional extent of which transverse to the longitudinal direction of the post is selected to be approximately 1n the order of magnitude of the post thickness.
