Description

Clip fastening clamp and a flat construct equipped with it

The present invention relates to a new clip clamp for a stable, nail-free and screw-free fastening of elongate board elements, preferably boards, planks or the like, which have longitudinal grooves on their lateral flanks on both sides, to beams of a sub- or supporting structure which have longitudinal grooves on both sides the formation of flat overall structures, such as in particular terraces, wall cladding, plank fences, billboards and the like on the basis of an angular C-profile with a rectangular central panel, of whose two opposite, mutually parallel side edges at right angles two mutually parallel leg panels, each with Mutually facing support beam groove engagement elements protrude at their free end edges in a first direction and from their central area in the opposite direction diametrically opposed to the first direction board clamps with clamp plates each facing away from one another and projecting board element groove engagement elements ment.

It also relates to a similar clip clamp for the construction of a flat structure, i.e. a terrace or the like, in which the board elements, i.e. floorboards, are arranged parallel to one another at an acute angle of no more than 45°, i.e. diagonally to the course of the parallel supporting beams with the center panel of the clip clip having the shape of an oblique parallelogram.

Furthermore, the invention relates to the planar construct itself, which can be created using the clip clamp according to the invention, and the method for setting up this planar construct.

A wide variety of suggestions for fastening boards, in particular decking boards, to substructure beams without the use of screws or nails have already become known, with reference to the following documents in particular:

KR 101683268 B1, EP 3090850 A1, US 2013025228 A1, WO 2006011173 A1 and WO 2015170205 A1.

These documents show one-piece fasteners for decking, which fix the boards to a substructure without screwing. This is done with the first four documents by spring-loaded clipping from below upstanding tabs of the fastener onto a substructure and snapping extensions on upstanding tabs into grooves or indentations in the floorboards.

According to WO-A1, the fastening elements are not clipped onto the beams of the substructure, but pushed onto them.

The terrace clips according to KR-B1 and EP-A1 come closest to the clip clamp according to the present invention in terms of their basic structure.

KR-B1 shows that the planks are fastened to the substructure without a gap between them and that the metal terrace clip completely encompasses the substructure beams.

As a result, individual planks cannot be easily detached from the decking clip, since it is not possible to intervene between the planks, the wood of the planks cannot work, and there is an additional distance to the floor for the flimme of the substructure or soil must be provided, which makes it difficult or difficult to attach the terrace clip anywhere on the beam.

According to EP-A1, the terrace clip engages with springs in a groove of the supporting beam of the substructure, but the fastening springs for the floorboards are designed in such a way that the floorboards are fixed with practically no gap to one another, so that the necessary distance for the Working the wood of the planks and for an intervention between the planks for easy detaching of a single plank from the composite is missing.

WO-A1 shows a decking clip which provides not just two but four tongues for engagement in the floorboards, the tongues having a barbed structure and engaging in a number of different grooves in the floorboards. According to this document, the terrace clip also encompasses the spar of the substructure. Again, the planks are laid without spacing between one another (see Fig. 10) and the engagement of the barbed tongues in several different grooves of the planks makes it difficult to detach a single plank from the bond in case of necessary repairs below the terrace.

The subject matter of the present invention is a novel clip clamp of the type mentioned at the outset, which is characterized in that that it is made in one piece from an elastically resilient material, in particular from a polymer material, preferably polyethylene terephthalate, that the support beam groove engagement elements of the leg plates and the board element groove engagement elements of the plates of the board clamps are each designed as groove engagement strips with a substantially rectangular cross-section , whereby the groove engagement strips of the leg plates and the groove engagement strips of the board clamps are aligned at right angles to one another, so that during the assembly of each of the board elements on the supporting beams extending at a right angle to their longitudinal extent, the clip clamps open with their two leg plates being resiliently bent apart the supporting beam can be slid until the groove engagement strips essentially click into the two longitudinal grooves in a form-fitting manner, and then each of the board elements with one of its Longitudinal grooves with spring-back bending of the board clamp can be slid onto their engagement strips, while with spring-back bending of the board clamps arranged adjacent to the respective support beam, the board element can be laid down with essentially form-fitting latching of the groove engagement strip in the other side longitudinal groove of the same.

In a slight modification of the structure of the new clip clip just described is one according to claim 2, which has a parallelogram instead of a rectangular center plate. Such a clip clamp is suitable for laying board elements at non-right angles, ie at an angle to the course of the supporting beams of the supporting structure of a terrace or the like.

The new clip is intended for attaching board elements to a sub or supporting structure. The clip essentially consists of a lower part, which is to be attached to the supporting structure, and an upper part, which holds the board elements.

The lower part is designed essentially as a C-profile, with the legs protruding downwards in the installed position being equipped at the lower end with inwardly protruding spring elements or groove engagement strips which engage in grooves on the beams of the supporting structure. On the lower part, two board clamps or board clamp plates protruding upwards are provided as the upper part on its lying base surface, which are rotated by 90° or by an acute angle of a maximum of 45° to the legs of the lower part, are arranged at a distance from one another that determines a joint size between the board elements. The board clamps also have spring elements which are provided pointing outwards for engagement in grooves on the side surfaces of adjacent board elements.

The product according to the invention is a one-piece clip based on the tongue and groove principle. It is essential that the tongues are used on the groove edges under tension. The new product only requires substructures with supporting beams and board elements, such as decking boards, grooved on both sides. In terms of material, the product is designed to be so flexible that it stretches when it is laid, i.e. when it is pushed onto the beams of the substructure and then springs back and engages in the grooves of the same. As soon as the springs are pulled, they can only be loosened with a certain amount of force.

This ensures that e.g. a terrace floor also holds firmly without further effort. This enables easy and quick access to the substructure or to the ground below the terrace itself, even after the floorboards of a terrace have been laid and used.

Boards that have already been laid can simply be opened up again at any point on a terrace to allow access to any sub-floor installations, such as LED under-lighting, etc., or to fish out lost objects. The difference to screwed or nailed terraces is that they have to be completely opened. The opening of terraces laid with the new clip clamps is made much easier by the distance between the two board retaining clamp spring plates on the structure that protrude upwards.

It is advantageous, especially for removing individual board elements, e.g. from a terrace, if the board clamps or their board clamp plates are arranged at a distance from one another, in particular of at least 3 mm.

This ensures a gap of at least 4 or 5 mm between the planks.

Furthermore, it can be advantageous to ensure that the lower area between the two board clamps or board clamp plates arranged at a distance from one another is rectangular or has an acute-angled V-shape. It is also preferred, especially with regard to the assembly of the board elements on the supporting structure, that the edges of the two groove engagement strips of the two leg plates that face the center plate are designed as rounded edges.

However, it can also be advantageous if the edges of the groove engagement strips facing the center plate and possibly also the outer end edges of the groove engagement strips of the board clamps are designed as rounded edges.

Finally, for the attachment of the board elements laterally delimiting the overall planar structure on both sides, it is advantageously provided according to the invention that the clip clamp is designed as a “half-clip clamp” which is formed by a smooth separating cut of a clip clamp according to claims 1 to 6 from which the plane of symmetry aligned in the direction of the plates of the two board clamps protruding from the middle plate is available.

As briefly mentioned at the outset, a further object of the present invention consists in a flat overall construct that can be created using the new clip clamp according to one of claims 7 to 15.

According to a slight modification of the flat structure just described, it can be provided that the middle plate of the clip clamps does not correspond to a rectangular area, but is designed as an “oblique” parallelogram, which allows the board elements to be laid at an angle of, for example, 45 to less than 90°, i.e "obliquely" to the course of the mutually parallel bars of the sub-construction is made possible.

The main advantages of the invention are in particular the following:

Due to the design of the clip according to the invention, e.g. the planks of a terrace are fixed to the substructure with a defined distance from each other of e.g. 5 mm. This allows the wood to "work" without restrictions, especially outdoors and as a result of the influence of the weather.

According to the invention, the latching of the engagement elements of the clip clamps is provided in or to the easily accessible narrow lateral flanks of the board elements and not in the longitudinal grooves the undersides of the board elements, which are absolutely incomprehensible during assembly from above and thus significantly impede and delay snapping in.

The material of the clip is chosen so that it is elastic enough not to be damaged when loosening individual planks and that the tensile forces necessary for a firm hold of the planks can be applied.

It can be released in a simple manner by first pressing the plank to be detached against the resilient board clamp plate on the opposite side of the plank by applying horizontal force on one side and then pulling the plank up and snapping the tongue out of the groove on the Side surface of the application of force can be detached.

Detaching an individual plank from the composite cannot be implemented in this particularly simple manner with the terrace clips of the prior art.

It is important to emphasize that the difference between the clip according to the invention and that of the prior art is that none of the clips that have become known allow you to exchange any plank, i.e. not specifically a single damaged plank for one exchange new ones while the others can remain in their place. It is only a matter of releasing the individual board elements, which according to KR-B1 are held in place by the clips on the underside, which in practice can only be done with "use of force", in which at least the clips below the board element are in danger.

The use of the fastening clip clamp according to the invention also allows a very free design of a terrace, because the three components supporting structure, clip clamp and board are uncomplicated and can be individually matched to one another.

According to one embodiment of the new fastening clip clamp, which particularly facilitates the placement of the board elements on the supporting structure, it is provided that at least the edges of the two groove engagement strips of the two leg plates facing the center plate are designed as rounded edges.

In terms of a labor- and thus also time-saving construction, it is advantageous if the edges of the groove engagement strips and possibly also the outer end edges of the engagement strips of the board clamps are designed as rounded edges.

According to the invention, a special embodiment of the new fastening clip clamp is also provided for the board elements that laterally close the new surface board element-support beam construct at its side edges, whereby it is designed as a half-clip clamp for fastening the board elements that laterally delimit the flat overall construct on both sides which is obtainable by a smooth “halving” separating cut of a clip clamp according to the invention along its plane of symmetry aligned in the direction of the plates of the two board-retaining clamps projecting from the central plate.

According to the invention, a flat overall structure using the new clip clamps according to the features of claim 8 is also provided. The flat overall structure is advantageously designed according to the features of claims 9 to 14.

Finally, according to the invention, a method for producing a planar overall structure according to claim 15 is also provided.

The invention is explained in more detail by way of example on the basis of the drawings:
