There are joint connectors (4) extending between the strips to hold them in place and carry mounting brackets for the panels supported on the posts. Each joint has clamp plates (9) with an opening for a retaining screw (23) extending through the plate and the gap between the strips. The clamp screws are removable and vertically adjustable with respect tot he posts. The barrier upper rail (7) is supported on brackets which fit into the upper ends of the posts.

Description

The invention relates to a railing according to the preamble of claim 1.

Railings of this type are used in particular for stairwells, galleries, balconies or the like. applied and have posts that consist of two parallel and spaced, post parts made of round or flat bars or the like are assembled. Such railings are known in two main variants.

In the first variant according to the type described at the outset, the node elements exist for the production of load-bearing, stable posts from two clamping plates, one Clamping bolt and a receiving part in the form of a threaded sleeve (US 3 804 374). The Clamping plates also serve to assemble the node elements and as spacers for the two post parts and are attached to the post parts from both sides created to which a gap between them borders. The attachment of the Node elements on the posts are made in that the clamping bolts from one side passed through the clamping plates and the gap and into the outside of one of the Clamping plates are screwed in. The latter also serves the Purpose of attaching a component in the form of a handrail to the post. This takes place in that further threaded bolts in the free ends of the threaded sleeves be screwed in, protrude through the mounting parts attached to the handrails and these fix by clamping on the threaded sleeve. The arrangement is construction-related such that the gaps are substantially perpendicular to the handrail, i.e. the them forming post parts in a direction parallel to the handrail or parallel to the stairs or the like. are spaced. Because of the gap formed between the post parts, it is also possible to move the knot elements along the posts, thereby the Adjust the height of the handrail. The advantage of the height adjustment of the node elements However, there is the disadvantage that not between adjacent posts easily also components in the form of filling elements such. B. filling rods, plates or the like. can be attached, which serve as safeguards against unwanted fall through, especially desired by children. For attaching such filling elements Rather, additional components would be required, resulting in a complex construction and assembly of the railing result.

The second variant of railings with two parallel post parts Post allows the attachment of between adjacent posts arranged filling elements, but not enough height adjustability of the individual Node elements (DE 37 05 394 C2, DE 295 09 791 U1, US 3 379 413). The node elements contain receiving parts in the form of those stored between the post parts Sleeves, with the pivot parts protruding completely or partially, screws od. Like., Are attached to this and have receiving openings into which Components such as filler elements can be inserted. The arrangement is by design such that the column essentially are arranged parallel to the handrail, i.e. the post parts forming them in one Direction perpendicular to the handrail or to the stairs. The advantage of the simple assembly of filler elements has the disadvantage of these railings, that their position between the post parts by the provided on these, for inclusion the pivot, screws or the like. Certain holes are fixed so that the node elements are not continuous, but only in a predetermined grid dimension the height are adjustable. Therefore, either the filling elements required in individual cases must be used be designed so that their assembly elements to the grid dimension in the Posts are adjusted, or there are some depending on the type of filler used Holes free. Both are not always desirable and could only be achieved through additional measures be avoided.

In contrast, the invention is based on a railing of the aforementioned Genre (first variant), the task of forming the node elements in such a way that they are also easy to assemble filling and other components are suitable.

The characteristic features of claim 1 serve to solve this problem.

Further advantageous features of the invention emerge from the subclaims.

1, a railing according to the invention has a plurality of spaced, in usually vertically mounted post 1, either with not shown Feet on the horizontal floor or, as shown, mounted parallel to them Anchor plates 2 on a vertical wall, e.g. a conventional stair string, be attached. The attachment of the anchor plates 2 to the post 1 can be done with Means not shown and for the purposes of the invention insignificant means respectively.

Between adjacent posts 1 are at a short distance from them and the ground first components arranged in the form of filling elements 3, which consist of rectangular plates exist, are arranged substantially perpendicular to the floor in the assembled state and serve as protection against falling through and / or aesthetic purposes. The Filling elements 3 are fastened to the post 1 with the aid of node elements 4 the node elements 4 in the longitudinal direction of the posts 1, i.e. 1 vertically displaceable are stored on these so that their altitude can be set as desired. The Node elements 4 have receiving parts 5, in which are attached to the filling elements 3, in the installed state essentially horizontally arranged mounting parts 6a Coming to lie. In addition, the same or similar node elements are preferably used 4, which are attached to the upper ends of the posts 1, for mounting a second Component in the form of a handrail 7, which preferably corresponds to the mounting parts 6a or similar assembly points 6b is provided.

As shown in FIGS. 2 to 5 in particular, the posts 1 are made of two parallel ones, here as Flat sections shown post sections 1a, 1b assembled, all over the Pass through the post height and are expediently identical. The post sections are aligned 1a, 1b with a constant distance in such a way that they are between them include a gap 8 running through the height of the post 1 and one in Cross-section form a square or rectangular hollow body, the two opposite Outside sides open and on the two remaining outside sides through the post sections 1a, 1b is limited.

The node elements 4 have a particularly preferred embodiment two clamping plates 9 and 10, one of a receiving body 11 and a clamping body 12 existing receiving part and a clamping bolt 14. The two are lying there Clamping plates 9 and 10 on those opposite, open outer sides of the Post 1 to which the gap 8 borders. Both clamping plates 9 and 10 are identical formed and each have a center hole 15 (see also Fig. 6). The in the assembled Condition facing sides of the clamping plates 9, 10 and the post parts 1a, 1b are provided with interacting guides. These exist in the exemplary embodiment each consisting of two parallel plates arranged in the clamping plates 9, 10, linear guide grooves 16 and correspondingly shaped, with little play in the guide grooves 16 usable longitudinal edges 17 of the post parts made of flat iron or the like 1a, 1b. As a result, the clamping plates 9, 10 are in the assembled state in Longitudinal direction of the post 1 slidably mounted on the post parts 1a, 1b, while on the other hand, the post parts 1a, 1b are kept at a distance by the clamping plates, since intermediate webs 18 between the guide grooves 16 serve as spacers.

The receiving body 11, which can be seen in particular from FIGS. 2 and 7 to 9, is a sleeve-like, a continuous receiving opening 20 having a hollow body, which also is provided with a passage 21 opening into the receiving opening 20, the The axis runs essentially perpendicular to that of the receiving opening 20. Against it the clamping body 12, which can be seen in particular from FIGS. 2 and 10, essentially massive, elongated body which can be inserted into the receiving opening 20 and which is here referred to as Internal thread formed threaded portion 22 which is perpendicular to it Has longitudinal axis.

To assemble the node element 4, the two clamping plates 9, 10 at facing guide grooves 16 aligned to each other to initially Clamping bolt 14 from the outside of the clamping plate 9 through the two central holes 15 (Fig. 6). Then the clamping body 12 in the receiving opening 20 of the Receiving body 11 pushed and arranged in this that the threaded portion 22 (Fig. 10) is aligned with the passage 21 (Fig. 9). In conclusion, that will two-part receiving part consisting of receiving body 11 and clamping body 12 placed the outside of the clamping plate 10 and the clamping bolt 14 with his External thread section is screwed into the threaded section 22 of the clamping body 12 to connect all parts of the node element 4 together. One on the opposite end of the clamping body 12 located head 23 can in the e.g. as a counterbore trained center hole 15 of the clamping plate 9 enter or different from outside to the edge of the central hole 15 of the clamping plate 9 acting as an abutment invest.

By appropriate spacing of the clamping plates 9, 10, it is now possible to in this 2 and 5 apparent manner to the two post parts 1a, 1b and to determine at the desired height on the post 1 that the clamping bolt 14th is tightened. Various embodiments are possible here.

In the embodiment of FIGS. 2 to 5 are before tightening the clamping bolt 14 from both ends of the receiving opening 20 forth two mounting parts 24 in the receiving body 11 inserted. The mounting parts 24 preferably consist of tubes or have cutouts 25 facing the clamping body 12. You also own Outer cross sections that are essentially the inner cross section of the receiving opening 20 correspond, and inner cross sections, which are essentially the outer cross section of the Correspond to the clamping body 12, which has a smaller outer diameter than that Corresponds to the inner diameter of the receiving opening 20. The tubular assembly parts 5 to the clamping bolt 14 into the receiving opening 20 introduced and in part on the effective as clamping portions 26 ends of the Clamping body 12 are pushed so that their peripheral portions between them and the wall sections of the receiving body 11 delimiting the receiving opening 20 come to rest. If the clamping bolt 14 is now tightened, on the one hand each Mounting part 24 between the associated clamping section 26 and the receiving body 11 and on the other hand the receiving body 11 between the mounting parts 24 and the adjacent clamping plate 10 clamped while simultaneously the two clamping plates 9, 10 are braced and fixed on the post parts 1a, 1b.

The embodiments shown in FIGS. 2 to 5 have the essential advantage themselves that for fastening and bracing all parts and for securing the axial Location of the mounting parts 24 only a single clamping bolt 14 is required. At the same time it is possible by using at least two node elements 4, one to obtain structural load-bearing posts 1 even if the two post parts 1a, 1b from two completely separate and only through the node elements 4 connected parts exist.

In a modification of the embodiment of FIGS. 2 to 5, it would be possible Clamping body 12 merely as a nut that can be inserted into the receiving opening 20 and the Assembly parts 24 as tubes or rods with the inner cross section of the receiving opening Form 20 corresponding outer cross sections. In this case, as a means of axially fixing the mounting parts 24 in the receiving opening 20 z. B. fastening screws are used, which are screwed into suitable threaded holes, the are formed in the receiving body 11 and open into the receiving opening 20.

The mounting parts 24 according to FIGS. 2 to 5 correspond to the mounting parts 6a according to FIGS. 1 and are on the floor of to be assembled between the posts 1, designed as plates Filling elements 3 attached. In contrast, Fig. 11 shows an embodiment in which serve the same node elements 4 for the assembly parts 6b according to FIG. 1 to record. All that is required for this is the receiving body 11 with respect to that in Fig. 5 position shown to rotate 90 ° about the axis of the clamping bolt 14 the axis of the receiving opening 20 is aligned parallel to the post axes. The Mounting parts 6b in turn have tubular, from above on the one clamping section 26 push-on end sections, which are fixed by tightening the clamping bolt 14 the node element 4 and the post 1 are connected. The free ends of the Assembly parts 6b can either be inserted into the associated bores in the handrail 7 or be connected according to Fig. 1 with sleeves 27, in which the ends of Handrail elements are inserted.

12 shows an embodiment without the clamping body 12 according to FIGS. 2 to 5 gets along. Otherwise, the same parts are provided with the same reference numerals.

In contrast to FIGS. 2 to 5, one of the two clamping plates 29 is one enlarged center hole 30 provided. A receiving body 31 has a continuous Receiving opening 32 and, in contrast to FIGS. 7 to 9, also instead of the passage 21 a threaded portion 33, which is useful in a rear, in the center hole 30 usable approach 34 is formed. The threaded section is used to hold the External thread portion of the clamping bolt 14, so that in this case the receiving part is in one piece and consists only of the receiving body 31. For the rest is training of the different parts analogous to Fig. 2 to 5. Because of the lack of the sprag 12 when tightening the clamping bolt 14 only the receiving body 31 against the clamping plate 29 can be pulled, the receiving body 31 additionally has two in its Receiving opening 32 projecting threaded bores 35, which in connection with it screwed fastening screws 36 as a means for axially fixing in the Receiving opening 32 can serve inserted mounting parts 37. It can be seen that, in contrast to FIGS. 2 to 5, massive assembly parts 37 are also used can. Such an arrangement is particularly useful when the plate-shaped filling elements 3 by a plurality of extending between the posts 1, parallel filler rods are to be replaced and the mounting parts 37 simply out the ends of these bars. Otherwise, the center hole 30 and the shoulder 34th preferably cylindrical, so that the receiving body 31 as the receiving body 11 of FIGS. 2 to 5 rotated as desired about the axis of the clamping bolt 14 and brought into any angular position relative to the clamping plate 29 or to the post 1 can be e.g. an adaptation to a not shown in the drawing To enable stairs.

13 finally shows a variant of the embodiment according to FIG. 12. On the post 1 here are two clamping plates 9, 10 designed according to FIGS. 2 to 5 guided, the protruding clamping bolt 14 into an internally threaded section is screwed in, which is analogous to FIG. 12 in a rear extension 39 of a receiving body 40 is formed. The approach 39 is dimensioned here so that it is conical Countersinks fits, which are formed in the clamping plates 9, 10 and for receiving of clamping bolts in the form of countersunk screws. There is also one Receiving body 40 having receiving opening 41 in a position analogous to FIG. 11, to be able to accommodate a mounting part 42 fastened to the handrail 7, which essentially is solid, but in the free end face, which in the receiving opening 41st comes to rest, has a threaded bore 43. In addition, the receiving opening 41 provided with a bottom 45 having a screw hole 44, so that in the assembled Condition a fastening screw 46 through the screw hole 44 into the threaded bore 43 can be turned. In this case, the fastening screw 46 forms a means for axially fixing the mounting part 42, so that only on one side of the receiving body 40 a mounting part 42 can be attached.

The invention is not restricted to the exemplary embodiments described, which are based on can be modified in many ways. For example, it would be possible to use the posts 1 composed of three or more post parts and, if necessary, the clamping plates to provide a corresponding number of guide grooves. Instead of flat gauges Existing post parts can also use differently shaped post parts in which case the clamping plates would have to be adjusted accordingly. Especially heat it is also possible to use one-piece posts where the gap through a longitudinal slot intended for receiving the clamping bolts or through the Space between two, at a distance from each other, but firmly together connected post parts is formed. Instead of using screws, the clamping bolts if necessary also consist of sleeves with internal thread sections, in which Case of the clamping or receiving body with a corresponding external thread section should be provided. The receiving openings for the mounting parts can also be used consist of blind bores, especially if, as in FIG. 13, only a single mounting part needs to be assembled. It is also possible, e.g. at transition points between horizontal and rising or falling railing sections, either the assembly parts 6a, 24, 37 to bend accordingly or the receiving openings 20, 32 with two to be provided at a corresponding angle to each other. It is also clear that all visible screw heads, if necessary, are not shown in detail Clamping inserts or cover caps can be covered so that none from the outside Fasteners are visible, and that the described node elements also for Installation of anchor plates or the like. (e.g. 2 in Fig. 1) can be used. Should the railing be installed e.g. the inner can only run horizontally Clamping plate (e.g. 10 in Fig. 5) is also missing, in which case the receiving body with corresponding guide grooves could be provided. The receiving body is preferably but rotatably mounted in the node element or on the post, so that Any stairs can be realized as required. Finally, it goes without saying that the individual parts of the posts and knot elements also in other than those shown and combinations described can be used.

The posts, node elements and their parts are made depending on the required stability Appropriately made of metal (steel), plastic or steel coated with plastic produced.
