At least one screw channel (14) is molded on one or both inner surfaces of the profiles and is formed by one bar (15) and a wall of one of the profiles or by two parallel bars. Preferred Features: The bars run parallel to the longitudinal axis (13) of the U-shaped profile.

Description

The invention relates to a kit for the manufacture of gates, fences, Railings or similar components made up of a variety of U-shaped Profiles which can be locked together in pairs, the Profiles in the assembled state form a closed box profile and with at least one molded on one or on both inner lateral surfaces Screw channels are provided, each consisting of a web and a wall one of the profiles or two mutually spaced parallel ones Webs are formed.

Such a kit is known from DE 26 11 822, which consists of two together latched U-shaped profiles, which acts as a horizontal Box profile work. Take two box profiles arranged parallel to each other vertically into these inserted rods so that by means of this construction a gate, a fence, a railing or the like can be built.

It has been shown to be disadvantageous in this door structure that the bars are in Circumferential notches are to be provided in order for this Insert the holes provided in the two box profiles and close them lock. However, this fixation of the bars does not guarantee reliable Force absorption, in particular of vertically directed forces, since the locking of the Rods are not secured and therefore a change in the locking position is possible.

DE 44 34 486 C2 is a fastening element for the production of fence panels can be seen in the inside of which screw channels are formed, in the Fastening screws for the bracket to be locked together Fasteners are screwed in.

A disadvantage of this gate or fence structure is that with a corresponding Effect of force on the individual profiles, especially in the cantilever or other components supporting profiles, a twisting or deformation of these Profiles are created. To create the necessary profile rigidity, the Walls of the profiles are wide. However, this leads to the additional Material requirements at higher manufacturing costs. In addition, the gate much heavier and therefore difficult to transport and assemble.

It is therefore an object of the invention to provide a kit for producing a gate, To create railings or fences of the type mentioned at the beginning, which the absorbs acting forces reliably, without the connection of the profiles thereby being solved. Furthermore, the fixation of the individual box profiles with each other in such a way that the type of attachment is visually appealing is designed so that the fasteners are not visible from the outside. Furthermore, the U-profiles are to be assembled and disassembled in a simple manner his.

This object is achieved in that in the screw channels or more stiffening members are used and that the or Stiffening members over the entire length or in some areas in the U-profile are arranged.

The mutual attachment of two or more neighboring and aligned mutually extending U-profiles are made by means of the stiffening members For example, half are inserted in a profile and thus in two adjacent profiles are arranged.

To the U-profiles locked together, for example on a base plate or to be able to attach to the adjacent box section, the webs of the Screw channel parallel or perpendicular to the longitudinal axis of the box section run.

The fact that the webs on the legs of the inner profile and parallel that can run to the connecting web of the internal profile internal profile attached to the base plate or another profile become; the outer profile thus visually covers the inner profile appealing way, so that the type of attachment is not visible from the outside is.

To fix two box profiles running perpendicular to each other are in the internal and / or external profile one or more through holes for Inclusion and mounting of a fastener incorporated and by the Fastening means an adjacent box section is fixed.

The attachment of two or more neighboring in alignment with each other arranged profiles is achieved in that a stiffening member in these profiles is inserted so that the stiffening member at least at the interface of two Profiles, preferably half each in this, is arranged.

Further advantageous developments of the invention result from the Dependent claims.

By means of the kit according to the invention, two profiles are locked together locked to other similarly shaped profiles so that a gate, railing or Fence is created, the box profiles of which are reliably and releasably connected are. The internal screw channels are used to hold the Fasteners or the stiffening members. After snapping on the outside Profile is covered on the inside of the profiles, so that a visually appealing Fence, railing or gate is created.

The construction of the gates, fences or railings according to the proposed type is easy and therefore quick to accomplish because of the through holes predetermined positions are incorporated so that the fasteners are in shape of screws can be screwed into the screw channels. The screws cut a thread in the inside of the screw channels so that Adjacent box profiles reliably and firmly to absorb forces are fixed together.

The fact that in the profiles over their entire length or in some areas several stiffening elements are used, which are fixed in the screw channels are arranged, it is ensured that the stiffening members bending and Record torsional moments and thus the fence to be erected, the gate or the like. can be made of a light material, such as aluminum, and nevertheless has a similar or the same stiffness and load capacity as this given a steel gate.

Due to the modular design, the gate or the fence can be connected to any local The situation can be adjusted in a simple manner. The stiffeners are used in some areas at the position in the profile to which the highest Act on forces or moments, so that material is also saved in this way, to keep the weight of the gate or fence as low as possible.

In Figure 1 is a kit 1 for producing a gate 2 consisting of a Revolving leaf 3 and a stationary gate fence 4 shown. Gate 2 is attached to the base 5 via a base plate 6. By means of the base plate 6 penetrating screws 7 a post 8 of the gate 2 is locked on this. To the Posts 8, two pivots 21 are attached, which support the rotary wing 3, so that it can be pivoted. The rotary wing 3 has an identical one Construction on like the fixed gate fence 4, namely two on the respective post 8, as explained in more detail below, attached horizontally extending cross members 9, between which vertically aligned rods 10 are fixed.

From Figures 1 and 2 is the type of attachment and thus the construction of the gate 2 can be seen, because both the posts 8, the cross member 9 and the Bars 10 are each made of two interlocking U-profiles 11 and 12 educated. In the direction of the respective longitudinal axes 13 of these components are on the Inner lateral surface of the inner U-profile 11 four screw channels 14 formed.

It can be seen in particular from FIG. 3 that the screw channels 14 are each made two spaced apart and parallel webs 15 are formed, which run perpendicular to the wall of the profiles 11. The screw channel 14 can but also by means of one of the webs 15 and a parallel one Inner wall of the profile 11 may be formed.

There are four notches 17 in the outer lateral surface of the inner U-profile 11 incorporated in the assembled state in the inner surface of the outside lying U-profile 12 engage molded lugs 18 so that the two U-profiles 11 and 12 are releasably locked together. The outer U-profile 12 covers thereby the open side of the inner U-profile 11, so that on this molded screw channels 14 are not visible from the outside.

In Figure 4, the screw channel 14 is perpendicular to the longitudinal axis 13 of the two U profiles 11, 12 arranged. The screw channel 14 is here by a Inner circumferential surface of a U-profile 11 glued base plate 25 parallel extending webs 26 formed. Between the webs 26, the screw 16 for holding an outside screwed-in light barrier or the like.

It can be seen from FIG. 5, such as the post 8 on the base plate 6 is attached. The through the base plate 6 screws 16 are in each screwed one of the existing screw channels 14 and cut it Internal thread in the webs 15 so that the inner U-profile 11 of the post 8 is fixed to the base plate 6.

In the two legs 20 and in the connecting web 19 of the inside and external U-profiles 11 and 12 are machined through holes are penetrated by screws 16. The screws 16 are in the screw channels 14 screwed in by adjacent U-profiles 11 so that they are in a vertical position Direction related to the post 8 are held.

According to Figure 6, the gate 2 is made of a variety of composite U-profiles 11 'and 12' formed by means of, preferably half inserted Stiffening members 31 are locked together. The stiffening members 31 can also in the ridges 8 in the area of, for example, the upper swivel joint 21 are inserted if the rotary wing 3 generates an increased torque that is to be supported. The rigidity of the U-profiles 11 'and 12' and the post 8 is thereby stiffened against torsion and bending without additional material or the material density must be increased. Rather, the gate 2 in Lightweight construction can be made so that the rotary wing 3 with reduced force is accelerated or decelerated.

Figures 7a to 10d are different cross-sectional shapes of the To see stiffening members 31. The stiffening members 31 are fixed in the Screw channels 14, which are aligned opposite, inserted. The outer U-profile 12 'is snapped onto the inner U-profile 11' in some areas. 7a and 7b, the stiffening member 31 'is a rod-shaped pin trained, the simple or in pairs in two opposite screw channels 14 is inserted.

From Figure 8 it can be seen that the stiffening member 31 "between one to the Inner wall of the inner U-profile 11 'adjacent to the web 15 and the inner wall is clamped. It is also in the stiffener 31 "incorporated a through hole 32 through one Fastening screw 33 is feasible. Thus, the inner wall of the U-profile 11 'stiffened over the length of the stiffening member 31 ".

9a and 9b, the stiffening member 31 "'or 31 ^{IV is} Z-shaped or X-shaped and is firmly anchored with the free ends in each of the screw channels 14. These cross-sectional shapes have different bending and torsion properties and become dependent used by the occurring forces and moments.

10a to 10d, the stiffening member 31 ^V or 31 ^{VI is} T-shaped or H-shaped. One leg of the T-shaped stiffening member 31 ^VI lies on the inner surface of the outer U-profile 12 ', so that a fastening screw can be screwed into this leg from the outside.

It can be seen from FIG. 10c that the stiffening member 31 ^V rests on two opposite inner surfaces of the U-profile 11 'and 12' and the stiffening member 31 ^V both snaps into two screw channels 14 and with the two U-profiles 11 'and 12 'is screwed.

The H-shaped stiffening member 31 ^VI can also be additionally fixed in this way according to FIG. 10d. For improved fixation of the stiffening member 31, residual cams 34 are formed on the opposite leg of the webs 15, which reliably hold the stiffening members 31.

From FIG. 11, a stiffening member 31 ^VII , which is designed to be resilient perpendicular to the wall of the U-profile 11 ′, is clipped into the screw channels 14. The stiffening member 31 ^VII is thus compressed for assembly in the direction of the arrow and inserted into the screw channels 14.
Accordingly, in the assembled state, the stiffening member 31VII pushes the two free ends of the U-profile 11 'apart, so that the latched-on U-profile 12' is firmly connected to the U-profile 11 '. This creates a closed box profile that can accommodate very high torsion and bending elements.
