Definitions
- the present invention relates to a connecting element for mounting a side guard according to claim 1 and a side protection system according to claim 11.
- Example of a widespread protective post which is attached to the edge of a ceiling on the principle of a screw clamp.
- a disadvantage of such side protection systems is that for securing a construction site, a large number of these protective posts is needed, each protective post is a relatively large, complex and therefore expensive part.
- Particularly disadvantageous is also the lack of versatility of this side protection systems, because protective posts can be fixed with this type of attachment only to specific components, namely on projecting ceiling edges, and for areas with special geometries such as staircases or very cumbersome with auxiliary equipment can not be mounted. For this reason, construction sites sometimes do without side guards, especially stairwells.
- such side protection systems are often such that certain work such as e.g. Floor panels can only be placed when the side protection system is removed. There is a risk that after work, the side protection is not or not properly, or completely reinstalled.
- the present invention now has the task of a connecting element for mounting a side guard and to provide a side protection system which allows flexible side protection to each
- inventive side protection system should also consist of a minimum number of different elements, each element is as simple and inexpensive to manufacture. It should also be provided as simple and versatile connector for mounting the inventive side protection system.
- FIG. 2 connecting element with rod
- Basis of the invention is a side protection system consisting of one or more rods 1 and one or more connecting elements 2. Die
- Connecting elements 2 are used to connect the rods 1 together or for anchoring the rods 1 to a building.
- a rod 1 has a round profile and is hollow, like a pipe.
- a connecting element 2 has at least one receptacle 21 for a rod 1 and a connection point 221 for connecting the connecting element 2 to a further bar 1 'or to a building G.
- the profile and the size of the receptacle 21 correspond to the profile and the size of the rod 1, which is inserted therein ( Figure 2).
- a round bar 1 and / or a receptacle 21 with a round profile are advantageous because the connecting element 2 can then be fastened around the bar 1 with any orientation.
- a rod 1 and a receptacle 21 with positive polygonal profiles can be used to prevent rotation of the connecting element 2 about the longitudinal axis of the rod 1.
- connection point 221 is an opening of the connecting element 2, which serves for receiving a threaded rod GS and for this either has a female thread or can be provided with a separate nut M.
- Junction 221 can be located at various locations on the connector 2 and in different directions with respect to the longitudinal axis L of the receiver 21 ( Figures 3a-c). It is particularly advantageous if the connecting element 2 has three connection points 221: a parallel connection point 221a with a longitudinal axis LI parallel to the longitudinal axis L of the receptacle 21
- the connecting element 2 has, for example, a first lateral projection 22a with a tangential connection point 221c and a second lateral projection 22b with a radial connection point 221b and a parallel connection point 221a.
- the second lateral projection 22b in this case is longer in the radial direction than the first lateral projection 22a.
- the connecting element 2 could have two radial connecting points 221b on opposite sides of the receptacle 21 or in each lateral projection 22a, 22b, wherein both lateral projections 22a, 22b could then have the same size.
- the parallel junction 22a and tangential junction 221c are continuous and open on both sides of the connector 2, so that a threaded rod GS can be inserted from both sides.
- Connecting element 2 to a building G using a Threaded rod GS is anchored, which is attached for example with a dowel in a hole in a ceiling or a wall.
- Figures 4a-b and 4c-d show, for example, how a rod 1 can be fastened in different directions to a building G by means of a connecting element 2 with radial joint 221b ( Figures 4a-b) and parallel joint 221a ( Figures 4c-d) ,
- the connecting element 2 is preferably fastened at a distance from the building G. If necessary for the strength of the threaded rod, this is reinforced with one or more nuts. On the one hand, the nuts increase the stability of the threaded rod and can simultaneously serve as spacers for the connecting element.
- a first rod 1 is inserted into the receptacle 21, a hole is drilled through the second rod 1', and a screw S is guided through this hole, which is screwed at a connection point 221 (FIG. 5).
- the advantage of this is that the second rod 1 'about the longitudinal axis of the connection point
- the connecting element 2 described is versatile and allows to connect a rod 1 with a building G or with another rod 1 'with great flexibility.
- further possible improvements of the connecting element 2 will now be described, which make it easier and cheaper to manufacture and easier to use.
- the connecting element consists of two connecting parts 2a, which can be connected to one another (FIGS. 6a-b).
- the advantage of a two-part connecting element 2 is that it is much easier to attach to a rod 1, since it does not necessarily have to be mounted on the rod 1, which in the course of assembly of the railing in certain situations is no longer possible.
- the two connecting parts 2a are connected with screws, and when tightening is a in the receptacle 21 inserted rod 1 between the
- Connecting parts 2a firmly clamped so that the connecting element 2 is secured against sliding along the rod 1 immovably.
- each connecting part 2a has at least one recess, which lie one above the other in the assembled state of the two connecting parts 2a and form the connection point 221.
- the recesses are radial recesses 222b, which are superimposed upon joining the two connecting parts 2a and form the radial connection point 221b (FIG. 6c).
- the recesses are parallel
- Connecting parts 2a are superimposed and a form parallel junction 221a. If a connecting element 2 is simultaneously provided with a parallel connection point 221a and with a radial connection point 221b, these can intersect (FIG. 6d). If a connecting element 2 has a tangential connection point 221c, each connecting part 2a has a continuous tangential opening 222c, which are superimposed upon joining the two connecting parts 2a and form a tangential connection point 221c (FIG. 6d).
- the parallel and radial joints 221a, 221b have no nut thread, but a profile in which a separate nut M can be inserted.
- the advantage of a separate nut M is that the connecting element 2 and the nut M can be made of different materials.
- the nut could, for example, be made of brass or stainless steel, while the connecting element is made of less expensive material, in particular of a metal or plastic casting, e.g. made of aluminium.
- the nut M is preferably a commercially available nut M.
- Connecting parts 2a are adapted to the dimensions of the intended nut M, so that it can be introduced in a form-fitting manner and secured against rotation and displacement about or along the longitudinal axis of the connection point (s) 221.
- Embodiment of Figure 6e is shown a nut M with hexagonal profile and each parallel or radial recess 222a, 222b of the connecting parts 2a has a corresponding hexagonal profile.
- a rod 1 is positioned in the receptacle 21 of a connecting part 2a, a nut M inserted as needed in the parallel or radial recess 222a, 222b of the connecting part 2a and the whole is by attaching and tightening a second connecting part 2a with each other attached.
- the diameter of each mouth of the parallel and / or radial recess 222a, 222b is preferably smaller than the width of the nut ( Figure 6e).
