Description

The invention relates to a fastening device for posts on a hard ground or substructure with alternating inclination, which has as a support for a post a firmly connectable to the ground or base base plate, wherein the post is pivotally connected to the bottom plate and the joint with a the bottom plate connectable, cylindrical joint sleeve having a circumferentially extending recess.

When erecting fences or railings, the fence or grid mats are fixed in sections between posts spaced at a certain distance and at these posts. The posts themselves must be firmly connected to the ground or a substructure and must then be vertical before the fence or grid mats can be attached. In order to connect posts with a stone underground, a paved surface or a concrete or stone wall, it is known to provide the posts with a rectangular welded base plate, which is firmly connected to the ground, for example, can be pegged. However, with these rectangular welded-on floor panels, the fence or railing posts can only be offset on a horizontal surface or the horizontal surface of a substructure, for example a horizontal concrete wall. For slightly inclined ground or slightly inclined walls, the posts can still be aligned vertically by one-sided underlaying the bottom plate. In order to fix fences on clearly inclined ground, clearly inclined, sloping walls, so far posts have to be made with a correspondingly inclined bottom plate. It should be noted that the slope of the ground or the wall can change over the intended course of the fence again and again. In order to determine the required inclination of the bottom plate for several, needed for the erection of a fence or railing post, therefore, extensive measurements along the intended course of the fence or railing are necessary before with the production and the Put the post can be started. It may be that each individual post with its inclined bottom plate can be used only at a very specific point along the course of the fence or railing to be erected, so that posts have to be manufactured individually; then it must not be confused when moving. The individual posts must be kept ready in a specific order. The preparation and the posting of such posts are so cumbersome, labor-intensive and costly.

By the DE 20 2011 003 830 U1 a fastening device for post-shaped objects in the ground is known. It consists of a ground socket, which has at its upper end a covenant with oblong holes and can be sunk into the ground. A likewise provided with slots alignment plate can be bolted to the collar of the ground socket. Through a central opening in the alignment plate then projects the post, guided by a longitudinal guide, with play deep into the ground socket and can strike the wall of the ground socket. The intersecting slots on the collar of the ground socket and on the alignment plate allow to move the alignment plate on the collar of the ground socket to a certain extent, so that the post in the ground socket can assume a vertical or slightly deviated from the vertical, slightly inclined position , In the desired position, the post can then be fixed by screw on the intersecting slots of the federal government of the bottom sleeve and the alignment plate. However, this device is only suitable to anchor posts in the ground, because the ground socket must, to achieve sufficient stability, protrude deep into the ground, which is possible only in sufficiently deep soil. Also, the post can take only a position deviating from the vertical by a few degrees. The inclination is limited by the extent to which the alignment plate is slidable on the collar of the ground socket to be fixed by the screw on the slots can, and by the stop the lower end of the post can be found on the wall of the ground socket ,

By the CA 2 698 662 A1 For example, a device is known which relates to an angularly adjustable mast or post which, when mounted on a sloped post Underground is to be installed by the angular adjustment can be adjusted to the inclination so that it assumes a vertical position. The device consists of a bottom plate having downwardly directed edges or corners with which the bottom plate can engage in the ground. A post can be flexibly connected to the base plate in order to adapt it to the inclination of the ground. The joint consists of a cylindrical joint sleeve in the form of a hollow cylindrical body which can be rotated about an axis defined by a screw relative to the bottom plate and fixed in a definable rotational position. In a portion of the wall of the cylindrical body is provided a circumferentially extending recess. A cylindrical holder, which also includes a pushed onto the cylinder coil spring which receives the post, can be moved along the recess and placed in a specific angular position to the bottom plate. With the help of another clamping screw, the holder can be fixed in the selected angular position. When using the device, the bottom plate is first connected to the ground The hollow cylindrical body is rotated about the axis defined by a screw to align the recess in its wall on the inclination of the ground and fixed in this position by means of this screw. The support for the post is moved in the recess of the cylinder wall in an angular position until the support or the post-receiving coil spring is vertically aligned. With the help of a second clamping screw, the holder is secured in this position.

The operation of the device is cumbersome and error prone by the joint in the form of the hollow cylindrical body must first be rotated and aligned on the bottom plate and at least two fixing or clamping screws must be tightened. The position of the respective part can change unintentionally. With the device, a post or a mast can be placed vertically, it is made with the post receiving coil spring as a holder but no static fixation but a movable connection. The operation is similar to the tilt rods in the ski slalom, where the tilt rods tip over when touched and then bring back independently in position, so straighten up.

Accordingly, this connection can not withstand great forces, such as on fences or railings, e.g. be achieved by wind, pressure or impact especially at the frontal impact at an angle of 90 ° to the fence axis.

After DE 30 13 604 A1 The lower end of a mast is attached via a hinge device on a base or bottom plate. The hinge device allows the mast, when erected from a horizontal position, to be brought into a vertical position by being pivoted in the hinge. In addition, the mast should be able to be rotated about its longitudinal axis in order, for example, to be able to pivot a radar screen carried by it. The joint consists of a joint ball on which a U-shaped holder with joint shell rests and is held by a screw. The screw extends through a guide slot in the joint shell into the base plate. Between the U-legs of the holder extends the mast base and is pivotally mounted on a U-leg piercing hinge pin. By pivoting the mast around the hinge pin, the mast can be vertically aligned.

The joint of this device is a combination of ball joint and hinge joint with positive connections. Thus, a mast can be well aligned in all directions and twisted, but the leverage of the mast can actually be absorbed only by other guying, because a ball joint can absorb only very limited vertical impact forces. The device has only the function of a flexible foot and essentially serves the erection of a horizontal mast, which must then be stabilized by other bracing.

By the DE 20 2011 052381 U1 is a post support known with which a to be mounted on a sloping surface post vertically, in two directions can be aligned. On a bottom plate a spherical cap is fixed, on which a hollow cylindrical lower part of a support member is seated. The post to be mounted is inserted via an upper part in the support element. The spherical cap has an eccentric recess into which a Screw from the support element and through a hole in the bottom plate protrudes into the ground. The support element consists of an adjusting sleeve with an internal thread and a lower part with an external thread, so that a height adjustment is possible. Also, this ball joint only provides a frictional connection, the high force effects, such as wind, pressure or impact, especially when frontal impact at an angle of 90 ° on fences, railings and the like, can not withstand. Although the connection described allows an adjustment of the post in all directions and an axial rotation. However, the adjustment are very limited by the hole in the base plate and the screw and allow only a relatively low inclination.

The object of the invention is to provide a fastening device for posts on a hard but uneven ground or substructure with varying inclination, which allows to adjust the inclination of each post of a fence or railing to be built in such a way to the inclination of the ground, that each post finally takes a vertical position. In this case, the connection of the post with the ground must withstand the high forces that can occur due to wind, pressure or impact on a fence or railing or the like.

This is achieved with a fastening device according to claim 1.

According to the invention, the joint sleeve of the post with the bottom plate hingeably connecting joint is fixedly connected to the bottom plate, and on the cylindrical joint sleeve in the circumferential direction of a joint shell is slidably pivotable, with this joint shell a fitting is connectable, the lower edges of the shape of the joint shell are vaulted accordingly, so that the fitting piece can be placed without play on the joint shell.

With this joint, a positive and non-positive connection between the post and bottom plate is achieved, which makes it possible to the post in to bring a tilted position relative to the bottom plate, as required for a respective location, but which, by the joint sleeve is firmly connected to the bottom plate, prevents a fence or railing post undesirable rotation of the post in the axial direction and also high forces acting on the fence or the railing forces withstand, even if these forces impinge at an angle of 90 ° to the fence or railing axis. The joint sleeve does not need to be fixed in a special step on the bottom plate.

Thus, preliminary, extensive measurements on the ground or substructure along the intended course of a fence or railing as well as the individual preparation of posts for the individual locations of the posts are unnecessary. In this case, the post can be connected directly or via a fitting with the joint.

According to a preferred embodiment of the invention, the fitting has a cross section corresponding to the cross section of the post to be fastened, and the post is slidable onto the fitting. The hinge allows the fitting and thus also the post to pivot with respect to the bottom plate.

The joint sleeve is preferably pressed firmly into an opening provided in the bottom plate and thus firmly connected to it.

According to a preferred embodiment of the joint, a transverse bolt, which has a threaded bore, are inserted into the joint sleeve, wherein the threaded bore is to be brought to coincide with the recess of the joint sleeve; the joint shell has a bore and can be held in the circumferential direction of the joint sleeve by means of a screw which passes through the bore of the joint shell and the recess of the joint sleeve and can be screwed into the threaded bore of the transverse pin.

Preferably, the patch piece placed on the joint shell together with the joint shell in the circumferential direction of the joint sleeve can be swiveled steplessly by 60 ° on both sides from a position perpendicular to the base plate. Accordingly, the position of the patch on the fitting post can be adjusted by a total of 120 ° to the slope of a terrain.

The joint according to the invention can be used with the help of different fitting pieces for all common post types and post profiles, such as round tube, Quadratrohr-, rectangular profiles, T-iron, angle iron, solid material u.a., as are common in fence or railing. As a material for the joint come the purpose according to steel, aluminum, stainless steel and all other types of metal or combinations of these materials in question.

Fig. 1 shows in an exploded view the items of a first embodiment of the fastening device according to the invention and Fig. 2 shows this fastening device in the assembled state before attaching a post. The fastening device consists of a bottom plate 1, which in this embodiment a rectangular shape with two rounded Side surfaces has and is provided with two mounting holes 2. As will become apparent below, the bottom plate 1 may be of different shape. In its center, the bottom plate 1 has a rectangular opening 3. In this opening 3 a round, cylindrical joint sleeve 4 can be accurately used, which has in its wall a circumferentially extending recess 5, which extends approximately over half the circumference of the joint sleeve 4. In the joint sleeve 4, a cross bolt 6 fits with a lateral threaded hole 7. When inserted for mounting the cross bolt 6 in the joint sleeve 4 and its threaded hole 7 is brought to the recess 5 of the joint sleeve 4 to coincide, the joint sleeve 4 in the opening 3 of Bottom plate 1 pressed and firmly connected to her, eg welded. Thereafter, an adapted to the shape of the joint sleeve 4 joint shell 8, which has a through hole 9, mounted by means of snap ring 10 and screw 11 on the joint sleeve 4 in the circumferential direction pivotally. The screw 11 passes through the bore 9 of the joint shell 8, which extends in the circumferential direction recess 5 of the joint sleeve 4 and is screwed into the threaded hole 7 of the transverse pin 6. A fitting piece 12 with a rectangular cross-section in this embodiment, the lower edges 13 are adapted to the shape of the joint shell 8 exactly, then can fit accurately, so without or with very little play, are placed on the joint shell 8.

By moving the post 15 on the fitting piece 12, the post 15 can be adjusted in height to a selectable size and adapted to external conditions and fixed.

In the exploded view according to Fig. 4 are the items of the fastening device according to Fig. 1 again in another direction, namely from diagonally below, shown. It shows how the individual parts in shape and size are adapted to each other, especially the course of the lower edges 13 of the fitting 12 according to the shape of the joint shell. 8 is clearly visible. Fig. 5 shows that from the items according to Fig. 4 assembled fastening device.

According to Fig. 1 has the fitting piece 12 in its one side wall, and here in the one narrow side, a in the longitudinal direction of the fitting piece 12 extending, cutout 14. If necessary, a support part, for example made of plastic, can be fastened to the post 15 (not shown), which serves as a support for a fence mat to be attached to the post. When attaching the support member to the post 15, for example by riveting, inward bulges (not shown) may form on the relevant post wall. The post 15 is then pushed onto the fitting 12 so that these bulges in the cutout 14 can slide.

The recess 5 of the joint sleeve 4, the joint shell 8 and the cross section of the fitting 12 at its lower edges 13 are adapted to each other and dimensioned so that the fitting piece 12 together with the joint shell 8 on the joint sleeve 4 and with respect to the bottom plate 1 of a vertical position according to Fig. 3 can be swiveled steplessly by about 60 ° on both sides.

For the setting of a post 15 is preferably proceeded so that first the bottom plate 1 of the fastening device is firmly connected to the substrate or substructure. Thereafter, the fitting 12 is pivoted by means of a spirit level and aligned so that it is perpendicular to the ground or substructure; It can then be fixed in this position with the help of a clamping screw. Thereafter, the post 15 can be pushed onto the fitting piece 12 and secured laterally by means of a fixing screw 16 or rivet, etc.

By the fitting piece 12 and thus also the post 15 can be brought into a relative to the bottom plate 1 by a total of approximately 120 ° continuously pivoted position, the position of a number of posts 15, with the help of a railing or fence to be built , to different and changing inclinations of the ground or substructure are adapted (see also Fig. 3 ).

There is no longer the need to measure the ground or substructure on which a fence or railing is to be erected, to ascertain its different inclination at the points where posts are to be erected, and then posts suitable for the posts concerned produce and set accordingly inclined floor slab. It must be made for all fences or railing only a number of identical posts and an equal number of fastening device according to the invention; the adaptation to the slope of the ground or substructure, as described above, on site. Mistakes in the posts at different locations are excluded.

At the individual parts of the fastening device changes are possible as needed, without departing from the spirit.

FIGS. 6, 7 and 8 show a second embodiment of the fastening device, which differs from the first embodiment described above by the shape of the bottom plate 1; here it has a rectangular-square shape and has four mounting holes 2. The remaining parts correspond exactly to those of the first embodiment. These two embodiments are suitable for posts 15 with rectangular cross-section, for example, the dimensions 60 x 40 x 2, as they are very common in fence construction.

FIGS. 9, 10 and 11 show a third embodiment of the fastening device according to the invention, which can be used when moving posts with a round cross-section. The bottom plate 1 here again has a rectangular-square shape as in the second embodiment, but it could just as rectangular and not square or rectangular with rounded side surfaces as in the above-described first embodiment; still other shapes of the bottom plate 1 are possible. Joint sleeve 4 with recess 5, transverse pin 6 with threaded bore 7 and joint shell 8 with hole 9 are identical to those of the first and second embodiments. Because this fastening device is intended to be suitable for posts 15 with a round cross section, the fitting piece 12 likewise has a round cross section, so that the post 15 can be pushed onto the fitting piece 12 and fixed with the fixing screw 16 without or with little play. The lower edges 13 and this round fitting 12 are arched according to the shape of the threaded cup 8 to accordingly Fig. 10 to be placed without clearance on the threaded cup 8 (see also Fig. 11). Fig. 10 shows the fastening device with slid onto the fitting piece 12 and fixedly held by a fixing screw 16 post 15th

The invention has been described by way of example with reference to three embodiments. In order to adapt the fastening device to external conditions, but even more changes are possible especially to the shapes of the items without departing from the actual inventive idea.
