Description

Self-locking locking connection of the supporting profile and the plate element

Field of technology

The invention relates to a self-locking connection of a support profile and a plate element forming an interconnection system, where the individual elements of the system enable the realization of a detachable connection serving primarily to attach a plate element of any shape to a support profile, e.g. a post. This connection is formed by two counterparts of the lock - the matrix and the belonging. Their interaction forms a locking connection regardless of their shape. The composition of the elements ensures wide application variability.

The plate element can be fixed in tangential and tangential arrangement with respect to the supporting part. In both types of arrangement, rotation and locking around the axis of the support profile is ensured. The stackability of the individual floors transfers the locking to the surrounding floors without the need for firm connections between the board element and the supporting profile. The assembly of the connection does not require any additional connecting elements or special tools. The self-locking locking joint according to the invention is designed in particular for fastening board elements as information carriers, e.g. orientation signs, advertising banners, etc. Thanks to the extraordinary variability, the system is also predestined for use in construction and interior design, ie. eg fences, screens, partitions, stairs, information pylons, enclosures and wherever a tangential or tangential attachment of the board element and the supporting profile is required. Reductions, form couplings and system adapters make it possible to create joints of load-bearing profiles and plate elements of any strength and shape. The board element can be made of any material, typically wood, plastic, metal, composite, etc.

Prior art

The standards of the current state of the art most often include the fastening of the plate element to the supporting profile by means of

- 1 CZ 2019 - 67 A3 strapping machines, special tools and various types of fasteners, such as screws, nuts, rivets, welds, adhesives, etc. These machines and tools are divided according to degrees into semi-automatic strapping machines, or hand strappers, which are in addition, a feed frame and automatic strapping machines are required, with a feed frame.

The common feature of these applications is, from our point of view, insufficient emphasis on design requirements, simple and directionally accurate assembly. It is almost always a mounting at heights of 3 meters above the ground and above. The use of additional elements and special tools makes them uncomfortable at these heights and increases the risk of injury. It is almost always a complex assembly that cannot be handled by a single person.

The manual strapping method consists in fastening by threading the tape through the buckle and around both connecting objects, further tightening with the help of tensioners and connecting the tape with a self-locking or deformation buckle, or by welding the tape. Without the described tools, the strapping method cannot be used at all.

Tools or mechanical tools, such as clamping pliers and tape, are always required for mounting on arbitrarily large diameters and profiles. The tape must also be tightened to the required tension. The fastening procedure consists in turning the pliers over the clip and cutting the binding tapes, then closing the clip by deformation with a hammer or with pliers that are adapted to deformation. Modification, repair, or any other manipulation is very difficult to implement.

The essence of the invention

The essence of the invention is a self-locking connection of the support profile and the plate element, forming a mutually modular connection system, where the individual elements of the system enable the realization of a repeatedly disassemblable connection serving primarily to attach a plate element of any shape to the support profile, e.g.

-2EN 2019 - 67 A3

The present invention is in no way limited by the shape of the profile, the exemplary embodiment presented here using a circular profile for illustration, where the supporting profile is a log post.

However, the person skilled in the art will easily understand the applicability of this solution to other profile shapes, such as square, rectangular, hexagonal, etc., as well as the way in which the individual elements of the invention are to be adapted to achieve the desired technical effects. of the invention.

To create at least one self-locking connection, a pair of locking elements is necessary, which delimits the space for seating other elements of the modular system. The locking element comprises a main opening through which the support profile passes, to which it is attached by at least one fixing member which passes through an opening formed in the side wall of the locking element and extends into the support profile. The locking element comprises at least two connecting openings for interconnecting the locking element with other elements of the locking connection according to the invention by means of connecting members, e.g. pins.

Preferably, the number of these connecting holes is increased so that they are formed along the entire length of the circumference of the locking element and further so that there is a minimum distance between the individual connecting holes, e.g. corresponding to their diameter, which ensures stepwise rotation of the adjacent locking element and its subsequent connection. with locking element. This adjacent element is the base of the locking joint. The angle of rotation of the base is determined by the distance of the centers of the individual connecting holes.

In a preferred embodiment according to FIG. 1, the fixing member passes through two side openings formed on opposite parts in the locking element and at the same time this member intersects the support profile. The fixing member according to this preferred embodiment is further preferably secured in the locking element by means of at least one pin embedded perpendicularly into the fixing member through the connecting hole of the locking element.

-3GB 2019 - 67 A3

The base of the locking joint comprises a main opening through which the support profile passes, the base comprising connecting openings for connection to a locking element or another base. Optionally, the base has the same configuration of connecting holes as the locking element, but from the point of view of the strength of the base, it may not always be advantageous for it to have a high number of connecting holes as a locking element. In case the locking element is used as an intermediate element between two bases, a high number of connecting holes is advantageous due to the possibility of choosing a small angle of mutual rotation of connected elements, i.e. locking element and base placed above it, which leads to very precise rotation of plate elements. seated in the supporting elements connected to the base.

The base comprises at least one recess for embedding other elements of the locking joint, in particular the supporting element of the plate element. In the embodiment shown in the accompanying figures, which are not limiting in relation to the invention, the base comprises at regular intervals exactly four recesses for inserting support elements, the angle of rotation between adjacent support elements being 90 degrees.

The support element of the plate element comprises a recess complementary in shape to the shape of the part of the base adjacent to the support element, as is apparent, for example, from FIG. 1. This connection is thus essentially formed by two counterparts of the lock, i.e. the matrix and the belonging. Their interaction forms a locking connection regardless of their shape. The composition of the elements ensures wide application variability.

The inner wall of the main opening of the base preferably comprises, at the location of the recess, a groove for countersinking of the latch of the support element securing the connection of the support element to the base. In a variant embodiment, which is not shown in the figures, the base further comprises at least one connecting opening at the location of the recess, into which the connecting member of the support element formed on the surface adjacent to the base recess fits, or the support element also comprises

-4GB 2019 - 67 A3 connecting hole instead of connecting member and both elements connected by an additional connecting member.

In a preferred embodiment, the wall of the support element adjacent to the support profile copies the shape of the support profile.

The support element further comprises a groove for embedding the plate element. The groove can be made in the cross-sectional axis of the support profile, or in an axis perpendicular to the cross-sectional axis of the support profile, i.e. in the tangent axis of the support profile. These two embodiments of the support element allow a tangential or tangential grip of the plate element and the support profile. Against the displacement of the plate element in the groove, the groove of the support element may comprise at least one protrusion and / or recess which is complementary in shape to the protrusion and / or recess in the plate element and forms a locking connection with each other, as can be seen e.g. 1 or FIG. 6. In a variant embodiment, the recess may completely replace the groove, see Figs. 4c and 4d, or it may penetrate the entire support element so as to form an opening in the support element, see Figs. 4a to 4d.

If the free position in the base is not used by connecting the support element, the recess is preferably filled with a blanking plug. The shape of the blanking plug complements the recess of the base and can be secured against falling out with a latch, as well as the supporting element. The base preferably comprises at least four recesses for engaging the support element, as can be seen, for example, from FIG. 1 and FIG. 2a.

To hold the plate element, two bases and two support elements are required, which are mirror-image of each other so as to abut the lower and upper edges of the plate element, as can be seen in FIG. 1 or FIG. 6.

As already mentioned, the plate element can be fastened in tangential and tangential arrangements with respect to the support part, i.e. the support profile. In both types of arrangement, rotation and locking around the axis of the support profile is ensured.

-5 CZ 2019 - 67 A3

A significant advantage of the present invention is the fact that the stackability of the individual floors transmits the locking to the adjacent floors without the need for fixed connections between the plate element and the support profile. The assembly of the connection does not require any additional connecting elements or special tools.

At least two locking elements are required to secure one or more self-locking joints of the support profile and the plate element. The seating of each plate element requires a bearing between two support elements. The number of support elements on one base is given by the number of free positions, ie the number of recesses created in the base. To close the pair of support elements gripping the plate element, two bases are required, which are mounted relative to each other in a mirror configuration and in fact form a pincer grip of the plate element.

In case two floors of self-joining connections are formed, an inter-storey splitter connecting intermediate bases by means of connecting members can be inserted between the individual floors. The hub includes at least two connecting holes and differs from the locking element in that it does not include a hole for inserting a fixing member. It is not necessary for the hub to be firmly connected to the support profile, since this function is ensured in particular by the extreme locking elements.

In a simple embodiment, the bases can be connected directly without the presence of a hub. However, this limits the possibility of fine rotation consisting in the absence of a higher number of connecting holes, since due to the strength of the structure it is advantageous for the connecting holes to be made at the base, which have retained the original height, which is not reduced by recesses. The hub serves in particular for the required directional rotation of one base relative to an adjacent base or other bases depending on the position of the adjacent base, unless another hub is inserted between them to further correct the directional rotation.

In a preferred embodiment, the inner wall of the base and / or the locking element and / or the hub adjacent to the support profile can

-6GB 2019 - 67 A3 contain at least one protrusion serving for a firmer clamping of the support profile.

The arrangement proposed here consists in the use of specifically designed modular parts, ensuring a simple, directionally accurate connection without the use of any tools. Such assembly can be handled without difficulty by one person with minimal installation skills. In addition, the system allows stackability and unambiguous directional and height configuration.

This can be defined outside the installation site thanks to the code marking on all modules. This fact is essential and indisputably innovative for building large-scale orientation systems. Configuration using code marking eliminates incorrect installation. In addition to the functional aspect, i.e. the unequivocally positive technical effects of the solution according to the invention, the aesthetic value of all the parts used to create a self-locking connection of the support profile and the plate element is also significant.

It is therefore advantageous if at least the base, the locking element and the support element contain a code designation corresponding to the configuration to be achieved by their interconnection.

In a further preferred embodiment, the individual parts, i.e. the base and / or the locking element and / or the support element and / or the plug and / or the hub, may comprise further recesses to reduce their weight. These recesses are usually on surfaces that are not visible after installation. This can be seen in Figures 2b, 3b, 4b, 4d and 5b.

Preferably, the material used to manufacture the individual parts is designed to be fully recyclable, resistant to weathering and UV radiation, which ensures its extremely long life and functionality of the entire system. This solution is not specifically limited to any suitable material providing a self-locking device

-7 GB 2019 - 67 A3 connection of support profile and plate element. Preferably, the material for the product of the individual parts is a thermoplastic, more preferably a polyamide, most preferably a polyamide with an admixture of glass fibers in an amount of 35% by volume, known for example under the name PA6-GF35.

Another advantage of the system is the unambiguous and precise rotation and locking of the individual parts, i.e. the base and the locking element, around the support profile.
