Description

The invention relates to a frame consisting of individual profiles which at least partially span a free cross section which is at least partially spanned by a network structure.

• - Bereitstellen fertig hergestellter Seilverbinder, die als Stanz- oder Tiefziehteil konzipiert, mit ihren auf eine Längsnaht zugestellten Endrändern zwei nebeneinanderliegende Seilaufnahmen begrenzen;
• - Auffädeln der einzelnen Seilverbinder auf parallel zueinander verlaufenden Seilen derart, dass zumindest eine Seilaufnahme eines Seilverbinders mit einer Seilaufnahme eines entlang des Seilverlaufs nachfolgenden und quer versetzten Seilverbinders in Deckung kommt;
• - Positionieren der in Seilquerrichtung verlaufenden Reihen der Seilverbinder auf den parallel zueinander verlaufenden Seilen an den in Seillängsrichtung einen Abstand zueinander aufweisenden Verbindungsstellen;
• - Verpressen der Seilverbinder zur Fixierung derselben auf den aufgenommenen Seilen an den Verbindungsstellen; und
• - Beabstanden der Verbindungsstellen der Seile voneinander unter Bildung der Netzstruktur.

Such a framework is in the patent publication EP 3 521 657 A1 shown, which relates to a method for connecting non-crossing ropes of a flatly expandable flexible network structure with ropes connected to one another at predeterminable connection points, characterized by the following steps:

• - Providing ready-made rope connectors, designed as stamped or deep-drawn parts, with their end edges aligned to a longitudinal seam that delimit two adjacent rope receptacles;
• - Threading the individual rope connectors onto ropes running parallel to one another in such a way that at least one rope receptacle of a rope connector coincides with a rope receptacle of a laterally offset rope connector that follows along the course of the rope;
• - Positioning the rows of rope connectors running in the transverse direction of the rope on the ropes running parallel to one another at the connection points which are at a distance from one another in the longitudinal direction of the rope;
• - Pressing the rope connectors to fix them on the picked up ropes at the connection points; and
• - Spacing the connection points of the ropes from each other to form the network structure.

In order to fix the net structure, it is wrapped around a frame, which can be part of a piece of furniture or a building. The frame is made of metal tubular profiles, which form a rectangular free cross section that is spanned by the network structure. Such frames, made up of individual profiles with an overarching network structure, can regularly be used as railing fillings, as fall protection in buildings, as protective nets for zoo and trade fair architecture or for special network constructions in the technical sector.

Furthermore, the property rights holder offers freely available, ready-to-assemble frame solutions on the market under the brand name “X-TEND”, which are made from slotted stainless steel edging profiles, which have slots on the inside to accommodate stainless steel cable nets, the mesh of which extends towards their free ends Combined in pairs in rope connectors, they are guided in a longitudinally displaceable manner in the slots mentioned.

Based on this prior art, the invention is based on the task of further improving the known frame solutions while maintaining their advantages, such as inherent stability and maintaining secure anchoring of the network structure within the frame profiles, in such a way that, in addition to the known steel and stainless steel materials for the Profiles of the frame other frame materials can be included. This task is solved by a frame with the features of patent claim 1 in its entirety.

The fact that, according to the characterizing part of patent claim 1, at least one of the profiles has at least one first recess, which serves to accommodate a part of the network structure, that the respective first recess is at least partially penetrated by a second recess, which serves to accommodate a fixing means, that holds the part of the network structure in position in the respective first recess, and that both recesses emerge from the profile in the direction of the free cross section, it is now achieved that parts of the network structure, regularly in the form of rope pieces, even in the respective profile of the frame are recorded and are held there in their receiving position in a defined manner by means of the fixing means, which positions the network structure on the frame via the second recess. By guiding a part of the network structure in the respective profile, any forces that may occur on the network structure are safely introduced into the respective profile of the frame and thus a force introduction for the network structure is achieved over a large area via the respective frame profile. In this way, even when high load forces occur on the network structure, the network structure is securely anchored in the profiles of the frame.

With regard to this new design concept for a network structure with a frame, materials can also be used for this, such as soft wood and plastic materials, which were previously considered unsuitable for use as frame or profile material due to their low stability. In this respect, as explained, preference had previously been given exclusively to steel and stainless steel materials; the latter because of their weather resistance.

Particularly due to the environmental or ecology movement, which focuses on nature conservation and green politics, natural materials, such as wood, are increasingly becoming the focus again for all possible applications and to meet the corresponding demands In order to be able to do this and to be able to provide the respective user with a frame system that is visually and haptically pleasing, the solution according to the invention has fulfilled this wish.

In addition to hardwoods, which are characterized by a large proportion of fibers and a narrow vascular structure, which result in a solid and heavy wood, such as beech, oak and ash or so-called ironwood, mechanically weak softwoods can also be used as profiles, especially for interior spaces for the frames process. In addition to the wood mentioned, standard plastic profiles can also be used for the frame structure with its individual profiles.

It goes without saying that the free cross section to be spanned for the network structure does not need to be constructed entirely from individual profiles of the frame, but rather the network can also be fixed to a third component, such as a wall or other fastening option, to which the frame can then be attached adjacent to its individual profiles.

In a preferred embodiment of the frame according to the invention it is provided that the first recess consists of a longitudinal groove in the solid material of the respective profile and the second recess consists of a bore which passes through the center of the longitudinal groove and opens on the bottom side at the same height as the groove base or opposite it Groove base is recessed. In this way, the respective recess can be obtained using simple tools, such as an end mill and a standard drill.

In a particularly preferred embodiment of the frame according to the invention, it is provided that the longitudinal groove, starting from its groove base in the form of a flat bottom surface, rises equally towards both sides at an oblique angle, which is preferably approximately 30° to 60° compared to the longitudinal orientation of the profile the free cross section passes over the entire length of the longitudinal groove at this point. Due to the respective oblique angle, a force is introduced from the network structure into the profile in a weakened form compared to a force introduction perpendicular to the longitudinal axis of the respective profile, so that a relief for the respective fixing means is created. In particular, a secure, force-relieved anchoring of the respective net mesh of the net structure in the profile base is achieved in this way.

It is preferably further provided that the fixing means is constructed in several parts, at least consisting of a clamping sleeve and an actuating part, which, when inserted into the clamping sleeve, expands it at least at one end and the clamping sleeve is thus in the second recess in the profile, preferably in a releasable manner. anchored. The actuating part is preferably formed from a conventional screw, which engages with an external thread in the associated internal thread of the clamping sleeve during the fixing process. Overall, an easy-to-assemble anchoring mechanism for the network structure in the frame with its profiles is achieved.

In a particularly preferred embodiment of the frame according to the invention it is provided that the net structure consists of individual ropes which are connected to one another via rope connectors to form net meshes at predeterminable connection points and that as part of the net structure, which is held in the first recess by means of the fixing means, a piece of rope serves as a net mesh. The respective cable connector can have a base body part which has a locking recess at one end as a connecting means, into which an assignable locking part at the opposite end can be inserted as a further connecting means of the base body part with such a precise fit that a self-contained fixing sleeve or press clamp is formed as soon as the clamp-like cable connector is closed to the sleeve. In this way, two adjacent rope sections of the net structure can be placed together in a defined manner to form a connection point, whereby the adjacent rope sections of the net structure do not cross each other. By using a large number of such rope connectors with the same structure, individual net meshes that are as identical as possible can then be achieved for the net structure.

In a preferred embodiment of the frame according to the invention it is provided that when the fixing means is fixed in the second recess of the profile, the free end protruding from the clamping sleeve holds the piece of rope guided in the longitudinal groove in position in the direction of the groove bottom, preferably presses it against the groove bottom. As a result, a secure positioning of the associated network structure in the groove base of the associated frame profile is achieved by means of the fixing means, with the clamping sleeve ensuring secure anchoring of the fixing means in the profile material. For a flush finish, it is preferably provided that in the fixed state of the fixing means, the head of the fixing screw rests on a profile side that faces the free cross section. In this way, good accessibility for the respective fixing means is also achieved, even if the frame is part of a third-party component as a railing filling.

In a further preferred embodiment of the frame according to the invention it is provided that the two recesses with the respective fixing means are made along the respective profile at predeterminable distances from one another and that the respective distance is based on the size of a net mesh of the net structure. In this way, the network structure with its individual, regularly distributed network meshes can be accommodated in the frame in a visually appealing manner.

In a further preferred embodiment of the frame according to the invention, it can be provided that the piece of rope guided in the longitudinal seam of the profile consists of two ropes of a net mesh, which are combined at their free ends via a rope clamp and that the rope clamp is in the second recess by means of the fixing means on the bottom side is recorded. In this way, the piece of rope with the two ropes of a net mesh is firmly anchored via the rope clamp in the profile base of the respective recess by means of the fixing means.

Accordingly, it is preferably provided for a frame that at least the profile with the two types of recesses consists of such a soft material that the clamping sleeve of the fixing means can be hooked to the profile material, which preferably consists of a wood material. The clamping sleeve can have a crown wheel or a ring gear at its one free end, which in the fixed state in the profile faces the environment, so that when the clamping sleeve is then hammered in, it is in the soft profile material, in particular during the screwing-in process with the associated fixing screw. the clamping sleeve cannot twist. An axial anchoring against the tensile forces occurring on the network structure is then ensured via individual locking parts which are arranged on the widening cross section of the clamping sleeve, provided that these engage in the wood cross section released via the second recess under the influence of the fastening screw.

Furthermore, the subject of the invention is a profile, in particular for building a frame as presented above, the profile having a first recess which serves to accommodate a part of a network structure, the first recess being at least partially penetrated by a second recess which is the To accommodate a fixing means that holds the part of the network structure in the first recess, and wherein both recesses emerge from the profile towards the environment. In this way, a tradable profile, preferably made of wood material, can be used with other suitable profiles to build a frame on site and the profiles and the network structure with the associated fixing means can also be sold as part of a sales set, for example through hardware stores.

The frame according to the invention is explained in more detail below using exemplary embodiments according to the drawing. The following are shown in principle and not to scale

• 1 to 3 a first embodiment of a net fastening solution on a profile of a frame;
• 4 to 6 a second exemplary embodiment, comparable to the illustration 1 to 3 ;
• 7 a frame made of wood material as a whole with a fixed network structure and with a plurality of network meshes which are connected to one another via rope connectors;

• 9 a side view of a clamping sleeve, which is taken in a profile shown in section, once with and once without a fixing screw, but without a net.

Starting with the 7 This shows a frame according to the invention consisting of four assembled profiles 10, which span a free, rectangular cross section 12 which is spanned by a network structure 14. Such a frame can be used in practice, for example, for a so-called railing filling. Furthermore, such a frame, which is not shown in more detail, can, for example, consist of only two individual profiles, which then spans a comparable cross-section with other third-party components, such as building walls, and the network is then stretched between the wall parts and the frame consisting of two frame profiles and to that extent kept in shape and position.

The net structure 14 consists in the usual way of individual ropes 16, which are firmly connected to one another to form diamond-shaped net meshes 18 at predeterminable connection points 20 via individual rope connectors 22 or rope clamps, so that a stretched net with net openings 24, formed by the net meshes 18, is created . Such net arrangements and their rope connections are state of the art and are exemplified in EP 1 536 157 B1 of the property rights holder. Parts of the relevant network structure 14 are created using individual Fixing means 26 held in the respective profile 10, which will be explained in more detail below.

That's how they show 1 to 3 a first embodiment of the frame solution according to the invention. The respective profile 10, which is in the 1 to 3 only in parts and in 1 is shown in half in the longitudinal section, a first recess 28, which serves to accommodate a part of the network structure 14 in the form of a rope piece 30 of an assignable net mesh 18, the rope piece 30 being part of a rope 16 with a further rope piece 32 as part of another Rope 16 are held together in pairs and to form a net mesh 18 at each end by a rope connector 22.

Like furthermore the 1 shows, the double-wedge-shaped, first recess 28 is penetrated transversely by a second recess 34, the second recess 34 being designed in the manner of a usual bore. For better presentation and understanding, profile 10 is in the 1 reproduced in the manner of a longitudinal section along the middle of the profile and only in connection with another corresponding profile half does the profile result as a whole, as exemplified in the 3 is reproduced in excerpts. Furthermore, the respective profile 10 is made in one piece and solid, as in the 3 , 6 , 7 and 8th shown. As the 2 further shows, the second recess 34 is penetrated by a fixing means 36, which holds the part of the network structure 14 in the form of the bottommost piece of rope 30 in position in the respective first recess 28, the relevant piece of rope 30 being fixed in the receptacle in the wedge-shaped diagonal course the first recess 28 follows. As can also be seen from the 1 to 3 results, the respective recess 28, 34 emerges upwards from the respectively assigned profile 10 in the direction of the surroundings or in the direction of the free cross section 12 of the frame.

Like the profile section after the 1 and 3 shows, the first recess 28 consists of a longitudinal groove 38 in the solid material of the respective profile 10 and the second recess 34, as already explained, consists of a longitudinal bore which passes through the center of the longitudinal groove 38 from top to bottom and opens out on the bottom side at the same height as the Groove base 40 of the longitudinal groove 38.

What happens next? 1 and 2 results, the longitudinal groove 38 rises from its groove base 40 in the form of a flat, circular bottom surface to both sides equally at an oblique angle a, which is preferably approximately 45 ° compared to the longitudinal orientation of the profile 10. With this angle a, the respective longitudinal groove 38 merges over its entire length into the free cross section 12, which is spanned by the network structure 14, at the edge. In the exemplary embodiment according to the 2 The relevant oblique angle a is approximately 45°, but can also have angle ranges between 30° and 60°.

The fixing means 36 is constructed in several parts and consists of a slotted clamping sleeve 42 and an actuating part 44 in the form of a conventional hexagon socket screw. According to the exploded view 1 the actuating part 44 in the form of the engagement screw is screwed into the clamping sleeve 42 from above, its free diameter expands towards its lower end and the clamping sleeve 42 is clamped in the solid material of the profile 10. For this purpose, the clamping sleeve 42, which can be seen in more detail from the 9 results in a continuous longitudinal slot 46 on both sides, which in turn is followed by semicircular toothing ribs on both sides, projecting in a wedge shape, which are intended for hooking engagement in the profile material. On its upper side, the clamping sleeve 42 points as shown in the illustration 9 further a toothed ring 47, which allows the clamping sleeve 42 to be driven in by hand, preferably using a hammer, along the second recess 34 in order to secure it in the profile 10 against radial rotation in the solid profile material, in particular when screwing in the fixing screw.

The actuating part 44 consisting of the screw has, which is not shown in more detail in the figures, a usual external thread which engages in the assigned internal thread, not shown, of the clamping sleeve 42 during the fixing process. The screw assumes its fully engaged position as shown after 3 a, the head 50 of the screw then rests over the entire surface on the top of the profile 10 and to this extent engages over the edge of the slot-like longitudinal groove 38. In the state of the fixing means 26 in the second recess 34 of the profile 10, as shown, protrudes towards the 2 the lower free end 52 of the screw emerges from the clamping sleeve 42, so that the lower cable piece 30 guided in the longitudinal groove 38 is held in position in the direction of the groove bottom or the groove base 40, preferably in this way the lower cable piece 30 is pressed against the relevant groove bottom 40 and Incidentally, the lower rope piece 30 runs as part of a diamond-shaped net mesh 18 along the solid material in an obliquely increasing manner with the angle a, which is just left free by the profile 10.

The 4 to 6 show opposite the solution according to the 1 to 3 a modified version Form, whereby the changed solution is only explained insofar as it differs significantly from the previous embodiment and accordingly the same components as described above are also shown with the same reference numerals and the statements made in this regard then also apply to the changed embodiment according to 4 to 6 .

In the modified embodiment, the lower rope piece 30 guided in the longitudinal groove 38 of the profile 10 is formed from two adjacent ropes 16 of a net mesh 14, which now has a substantially vertical extension direction, contrary to the horizontal orientation of the first embodiment. The two ropes 16 are in the direction of view 4 and 5 Seen at their free lower ends, they are combined as a rope connector via an associated rope clamp 26, which is accommodated on the bottom side in the second recess 34 by means of the fixing means 26. For this purpose, the second recess 34 in the form of the bore passes through the groove bottom or groove bottom 40 to form a blind hole 56, which in this respect only forms a circumferential contact ring 54, from which in an oblique course, now at an angle a of approximately 60 °, on both sides first recess 28 merges in the direction of the free cross section 12.

Like this in particular 5 shows, the bottom cable clamp 26 with its approximately oval cross section is accommodated precisely in the associated blind hole 56. The lower free end 52 of the engagement screw can again press equally on the lower now divided cable piece 30, 32 or as in 5 shown, the lower outer edge of the clamping sleeve 42, which is hooked in the solid profile material, now takes over the fixing along the V-shaped edge cross section of the longitudinal groove 38. Otherwise, the alternative solution according to the 4 to 6 Create comparable network coverage, as in 7 for the horizontal network mesh according to the embodiment according to 1 to 3 shown.

8th shows an enlarged image detail of a frame part as it appears in the direction of the 7 seen at the bottom right. It shows up according to the 8th that the distance of a pair, formed from a first recess 28 and a second recess 34, in sequence to the next arranged pair together with the associated fixing means 36, approximately corresponds to the distance between the adjacent rope sections of a net mesh 18.

With the solution according to the invention, it is for the first time reliably possible to create a network structure cover for a frame composed of individual profiles 10, which consists of a wood material and is accordingly soft, offering less resistance to the network structure definition than when using metallic solid or hollow profiles. In addition to wooden profiles 10 with a rectangular cross section, it is also possible to use such profiles in the type of round timber (not shown). In any case, the network structure 14 with its individual network meshes 18 is accommodated in the frame at the edge via the fixing device according to the invention and is securely anchored to the floor in such a way that even when high forces occur on the network structure 14, a secure frame construction with network structure cover is achieved. This has no equivalent in the prior art.
