DESCRIPTION

Railing device for structures to be secured against falls and railing post device therefor 05

TECHNICAL AREA

The present invention relates to a railing device for stairs, balconies, parapets or similar structures to be secured against falls, comprising a handrail with handrail sections, a connecting device for adjacent handrail sections, railing post devices which are connected to the handrail sections on the top side and to the structure on the bottom side, and railing elements running between the railing post devices.

The present invention further relates to a railing post device for a railing device with a railing post which is fastened to the structure, in particular a stair step or stringer, and which is connected on the upper side in an articulated manner to a handrail section, namely via a railing post element which can be connected to the railing post, and a railing handrail element which can be connected to the handrail section, wherein both elements are connected via a common joint.

Such structures require handrails for safety when walking or supporting. Since, for example, stairs are designed with different gradients and different turns, the handrails must be designed accordingly in order to adapt to the respective requirements. There are many attempts to create easy-to-install handrails that can be adapted to the different inclinations and

Handrails that can be adjusted to bends and angles. In order to enable the economical use of railings, handrails for stairs with different inclines, for example, must be assembled from individual straight pieces. If the angles of the various sections of the handrail that are to be joined together are known, they can be prefabricated at the factory, at least in part, using computer-aided calculation, design and manufacturing units. However, practice shows that, especially for stairs that have to be adjusted to the unavoidable tolerances on site, the handrails must also be assembled accordingly on site.

STATE OF THE ART

If a bend has to be made within a straight running part due to a different inclination, this can be done relatively easily by making a clean cut on the bisector, which is best done in the factory. However, any bend with a sharp corner inevitably leads to imperfections in cuts made during construction. Even the solutions known for load-bearing stringers and/or handrails, for example according to GB-A-2 147 022, DE-GM 71 37 304 and DE-GM 75 39 028 = DE-OS 25 55 041, have complex, precisely coordinated joints and joints that have to be machined very cleanly.

0 The handrail supports that rise vertically in the stairwell and at the lower and upper ends of each flight are familiar from conventional staircase construction. These were combined with handrail sections that were connected to suit the profile in order to achieve a smooth, continuous railing.

which require correspondingly clean craftsmanship, which is no longer available today for assembly railings at an economically justifiable cost.

The attachment of a continuous handrail made of wood or wood-based materials to differently inclined sections of the run with quick-assembly struts also requires individual adjustment to the building. It is important that subsequent corrections can be made without leaving any visible traces.

EP 0 264 085 Bl describes a stair handrail in which corner pieces are provided as connecting means in the joint area, which have two connecting side surfaces at an angle to each other in a recessed arrangement. The connection is made using fastening means such as screws, dowel anchors, clamping elements or the like. It is assumed here that in the case of rapid adjustment and assembly work, even by average craftsmen or fitters, small angular inaccuracies always occur when the handrail sections are cut off at the front due to dimensional adjustments and that the cut edge sometimes has smaller or larger breakages. By connecting the handrail sections in the recessed surfaces, these

DE-OS 29 24 999 discloses a staircase with a railing in which the upright railing parts are made of extension rods that protrude from the step surface and form a load-bearing connection with a stiffened rope handrail using a clamping system. In this design, the lower pipe section is directly screwed on with a relatively large thread. The connection between the lower pipe section and the extension rod is made using a metal clamping connection, either with an expansion screw whose shaft section tapers or with the help of a union nut on the slotted end of the lower pipe section. The connection between the extension rod and the rope handrail is made using a clamp that is directly screwed on. All of these metal parts require a very high manufacturing effort. In the course of the necessary reduction in construction costs, mechanically processed metal parts are no longer justifiable for so many railing rods.

DE 33 42 668 C2 shows a railing rod of the type mentioned above, which has proven to be very effective in practice.

A plastic clamping sleeve is used to lock the rod element, which can be produced economically and ensures a permanently reliable clamping function in conjunction with the union nut used.

DE 39 20 260 A1 shows a railing with a railing rod that also has a lower tube part and an extendable rod element. A specially designed clamping screw device is used to lock the position of the rod element on the lower tube part.

It is also known to use ropes between the railing post devices as railing elements, which run essentially parallel to the respective handrail and can be tensioned to the railing post devices.

WAYS TO CARRY OUT THE INVENTION

Fig. 1 shows a development of a two-quarter-turn support bolt staircase 80 that leads to a landing 64. A railing device 70 is arranged on the staircase 80 in the stairwell area, which is also present in the area of the staircase landing 64. The railing device 70 has a round profile handrail 54 that consists of straight handrail sections 54.1, 54.2, 54.3 and 54.4.

Between adjacent handrail sections, there is a spatial bend corresponding to the geometry of the staircase 80. In this area, a connecting device for connecting adjacent handrail sections 54 ... is arranged. The connecting device 72 has two hemispherical elements that can be arranged at any spatial angle to one another and to which the respective handrail sections 54 ... are connected. Such a connection technology has proven very successful in practice and is described in detail in EP 0 688 920 B1.

By using the spherical connecting device 72 in conjunction with the round profile handrail 54, a handrail is provided that has a pleasant grip and can be easily adapted to any spatial geometry. Individual components are used that can be manufactured economically in large-scale production.

In the immediate area before and after a connecting device 72 there is a railing post device 60 which is connected on the underside to the respective handrail sections 54... The railing post devices 60 are mounted on the steps 50 of the staircase 80. The connection of the railing post devices 60 to the steps 50 will be described in more detail below using the illustration in Fig. 3. The railing post devices 60 are height-adjustable and connected in an articulated manner to the handrail sections 54..., which will also be described below.

20

Railing elements designed as cables 74 are stretched between the railing post devices 60 arranged in the end region of a handrail section 54.1... The cables 74 run parallel to one another and parallel to the respective handrail section 54.1... .In Fig. 1, a total of five cables are arranged per handrail section.

The ropes with their tensioning elements are also designed as mass-produced components that can be manufactured economically and ensure easy assembly.

The fact that a railing post 10 is arranged at each bend point of the handrail to the right and left of the connecting device ensures a high level of rigidity. All components used, such as handrail sections,

Spherical connecting devices, railing post devices and ropes are designed as mass components that can be produced economically. The railing device according to the invention therefore guarantees extremely economical production, simple assembly and permanently reliable function. The fact that there are no recesses in the handrail in the area of the spherical connecting devices means that a pleasant grip is achieved. The railing device according to the invention can be easily adapted to almost any geometry.

The connection of the railing post device 60 to a stair step 50.1 in the support bolt staircase 80 is shown schematically in Fig. 3. The railing post device 60 has a railing post 10 designed as a T-profile. The lower end face of the railing post 10 is welded to a circular disk-shaped flange 22, to which in turn a web sleeve 24 with an internal thread 26 is welded centrally on the underside.

The flange 22 has a slight camber, which is shown in Fig. 3 in a greatly exaggerated manner as a dashed line 29. The camber ensures that the underside of the flange 22 rests fully on the top side of the stair step 50.1.

The first step 50.1 has a continuous recess 52, within which the web sleeve 0 24 is inserted in the upper area when the railing post 10 is mounted. The second step 50.2 arranged in the overlap area below the first step 50.1 also has a continuous recess 56, which is arranged in line with the recess 52 of the first step 50.1.

Between the two steps 50.1, 50.2, in alignment with the recesses 52, 56, there is a support bolt 34 with a continuous recess 44, which in a known manner has an upper sleeve part 66 with a circular ring flange 67 and a lower sleeve part 68 with a circular ring flange 69. The height of the support bolt 34 can be adjusted by screwing the two sleeves 66 and 68 together.

A further circular ring flange 76 is arranged on the underside of the second step 50.2. The railing post 10 is now connected by inserting a threaded rod 58 from below through the recesses 56, 44 and 52, which is screwed into the internal thread 26 of the web sleeve 24 by means of a sleeve nut 46 attached on the underside, whereby the connecting structure is braced overall and a stable mounting of the railing post 10 is ensured.

The T-shaped railing post 10 is arranged such that its flanges 42 are parallel to the handrail section 54 ... and its web 40 is arranged perpendicular to it, pointing towards the stairwell.

The connecting elements of the railing post 10 to the respective handrail section 54.1 are shown in more detail in Figures 4 to 7.

Railing post element 12 is mounted so that it can be adjusted in height within the sleeve 18. In order to secure the final height position in its position, the railing post element 12 has a profile 20 in its lower end region (see Fig. 7) into which a screw element 48, in particular a grub screw, can be inserted in a form-fitting manner through a recess 38 in the wall of the sleeve 18.

In the upper end area of the railing post element 12 there is a joint 16, the joint axis of which is perpendicular to the plane of the sheet. A rivet is used as the joint bolt, which is mounted in corresponding recesses in the railing post element 12. At the same time, an articulated handrail element 14 is rotatably connected to the joint 16, which has a bearing shell 15 that is adapted to the round contour of the handrail section 54.1 and is connected to the handrail section 54.1 via two screw elements guided through recesses 17.

In Fig. 8, the positioning of the recess 36 in the web 40 of the railing post 10 is shown schematically by a dark circle 41. The web 40 is milled out with this circle diameter to produce the recess 36.

Fig. 9 shows a schematic view of the connection of a cable 74 to the flange 40 of the railing post 10. The railing post 10 has a recess 82 in its flange 40 corresponding to the inclination of the cable 74.

A connecting element having an external thread 86 is clamped onto the end region of the cable 74.

On the side of the flange 40 opposite the cable 74, a screw sleeve element 88 with an internal thread

90 is present, which is inserted into a recess 92 of a wedge element 94, the wedge element 94 having an inclined surface 96 which comes into contact with the outer surface of the web. The shaft of the screw sleeve element 88 is guided through the recess 82 of the web 40 of the railing post 10 and the connecting element 84 of the cable 74 is screwed via the external thread 86 to the internal thread 90 of the screw sleeve element 88. For this purpose, the screw sleeve element 88 has a hexagonal contour 98 formed in its outer end face for the attachment of a tool.

15

Below the handrail section 54.2, in the middle thereof, another railing post device 60 is arranged. This has inclined recesses in its flange through which the respective cable 74 is guided. The edges of the recesses have an additional wear layer or a wear element.

Figures 12 to 15 show a schematic representation of a second embodiment of the connection of a cable 74 to a railing post 10. For this purpose, the web 40 of the railing post 10 has a slotted hole recess 106 of width B and length L. As can be seen from Figure 12, a relatively thin, frame-like, circumferential elastic element is clipped into the bearing recess 106 on the wall of the bearing recess 106. A bearing element 116 is mounted on a stop in the bearing recess 106 itself, which is designed as a circular disk element with a diameter D that is larger than the length L of the bearing recess 16, and a width Bl that is slightly smaller than the width B of the bearing recess 106. By selecting these dimensions, the bearing element 16 can be mounted on a stop within the bearing recess 106. At the same time, the bearing element 116 has a radial

Blind hole 118 with an internal thread into which a connecting element 110 can be screwed via a bolt 13 6 with an external thread in order to connect the cable 74. The connecting element 110 is designed in the present embodiment as a turnbuckle element known per se.

Figures 16 to 18 show an embodiment of the connection area of a plate-shaped disc element 101 to the railing post 10. The bearing element 120 has a U-shaped cross-section when viewed from above, the clear inner width of which essentially corresponds to the web of the profile 10. This allows the bearing element 120 to be pushed onto the web of the railing post 10 and screwed to it, which is not shown in more detail in the figures.

The connecting element 122 for the disk element 101 consists of an upper and lower jaw part 124.1, 124.2. The two jaw parts 124.1 and 124.2 are clamped together and the disk element 101 is clamped using two grub screws 126 perpendicular to the clamping plane. When screwed together, the geometry of the jaw parts creates a slot-shaped recess 128 that is open at the front, top and bottom and in which the disk element 101 is clamped. The wall of the recess 128 is covered with a layer of elastic material.

The connection of the connection element 122 to the bearing element 120 itself is made via the upper jaw part 124.1, in the base of which there is a recess through which a screw element 130 can be screwed into a corresponding blind hole recess 132 with an internal thread on the bearing element.

Figure 19 shows a variant of the connection of the handrail 54 to the railing post 60. On the underside of the handrail 54 there are blind hole-shaped recesses 104. The actual connection between the handrail 54 and the railing post 10 is made via a connection profile 100, which has a first leg 102 pointing upwards and a second leg 103 that is inclined. The connection profile 100 is designed as a curved round bar profile. The second leg 103 is connected to the railing post parallel to the inclined upper incline of the post by means of a weld seam 105.

The first leg 102 pointing upwards is inserted into the recess 104 on the handrail 54 during assembly. Any length adjustment that may be required is easily possible. This means that height adjustment within specified limits is also fundamentally possible with this design variant.

0 In order to ensure a secure connection of the first leg 102 with the handrail 54, silicone or polyurethane glue is introduced into the area between the first leg 102 and the recess 104.
