Abstract

Worktop connector for lightweight panels with a core layer of monodirectionally extending web structures, characterized in that the connecting element (11) can be inserted into the channels (5) of the lightweight board.

Description

In a connecting fitting for connecting a plurality of components, in particular of two butt-joined worktops in lightweight construction with monodirectionally extending web structures, a connecting element is inserted into at least one worktop, by means of which a connection of the plates with each other, other furniture elements or the building is made.

The invention relates to a worktop connector for lightweight panels or connecting fitting for connecting a plurality of components, in particular two blunt abutting worktops, preferably those according to the EP 2525010 B1 are made, with at least two connecting elements which are inserted at least one plate end face in the cavities.

Worktop connectors are made DE 20 2008 012 005 U1 . DE 29717630 U1 and GM 8023 825 known. They serve to firmly attach two adjacent worktops to each other so that a working surface that is continuous for the user is produced without an abutting edge. The connection fitting is usually milled from the bottom of the worktops ago and stretched from there via tie rods. For flush positioning, grooves for straightening blades are additionally milled in each case on the end faces or side surfaces, or holes for dowels are set for positioning.

In a known design, the connectors have the disadvantage that for the attachment of the positioning groove, as well as for making the receptacle for the mounting hardware special tool is required and a very accurate operation is required. In addition, worktop connectors with clamps when used for lightweight panels often transfer their traction only to the topcoats, thereby allowing either greater deckle thicknesses or only lower traction forces.

The specified in the protection claim 1 invention is based on the problem to provide a flush worktop connection for lightweight panels, which can be performed with simple tools and at the same time ensures high strength.

This problem is solved with the features listed in protection claim 1.

With the invention it is achieved that the connection of the worktops can be done with the simplest tool. Tailored worktops can be connected to each other without special drilling and fitting milled using a commercial cordless screwdriver, the new connection fitting and possibly a hexagon socket wrench or screwdriver, straightening, dowels o. The like. Are not required because even through the connecting element flush alignment of the plates to each other. By a particularly large force distribution higher tensile forces can be realized.

Mainly the assembly takes place from the underside. In exceptional cases, the assembly of the top plate can be made. After inserting and securing the connecting elements in the channels of a front side, the second worktop can be easily pushed. An attachment of the connecting elements can be achieved by form, force or material connection.

As a preferred connection, a screw-through from the bottom of the cover layer into the inserted connection fitting can be made. It is both possible to screw through directly without pre-drilling or make a pre-drilling before. The position can be marked by means of a template, where no high accuracy is required. Additionally or exclusively, the connecting element can also be glued in by means of adhesive. Another alternative is an oversized fastener, which is taken.

By the predetermined channels of the lightweight board, the plates are aligned with each other by means of the inserted connection fitting. In the case of a blunt connection, correspondingly shaped connecting elements can preferably be inserted in an E-shape. For miter joints, the fasteners can be used in a corresponding bend. As a further variant, a connecting element consisting of two blocks - joined together like a hinge - is provided for flexible angles. This is equipped in a special design with tension elements. Another alternative is the connecting element in a narrower variant, so that it can be slid obliquely into the channels of the lightweight board.

As materials for the fasteners are solid wood, preferably softwood, three-layer solid wood, milled solid wood, plywood in a flat orientation, plywood in a vertical orientation, plywood with wood-based material layer or with Holzwerkstoffabdeckungsicht, chipboard or fiberboard also multi-bonded, sandwich structures with middle layers of lightweight material, Sheet metal planked materials or sandwich panels with a dense Middle layer, planked profiles, hollow elements made of wood materials or solid wood, pipes, preferably made of light metal, plastic profiles in a variety of cavities and solid plastic blocks and WPC materials provided.

To connect the worktops with each other, two connecting elements can be inserted into one of the outer hollow chambers. In a particularly preferred variant, three connecting elements can be inserted. It is also possible to use a higher number of fasteners. The second work surface is pushed onto the protruding connecting elements of the first plate. The connection can be made here as a plate extension, edge termination, in miter angles, dull, on cabinet carcasses or on the building. For worktops with a round longitudinal edge, a small miter can be added. In another version can be connected to a continuous worktop another worktop in the T-direction dull or sharpened. The connection can be made detachable by screwing or permanently by gluing.

To achieve a tension connection, a diagonal screwing of the second worktop can be made to the connector. A particularly preferred connection is the connection through a connection fitting with tensioning device. The connection fitting consists of two solid basic bodies, which are kept at a distance by means of a soft spacer layer. The tension can be done here by means of eccentrics, Zugbeschlägen, cable ties or strapping. When using the tensioning device, first the operating hole for the tensioning mechanism is drilled according to a template. Subsequently, the base body, which contains the clamping device inserted into a worktop and fastened, so that the second tethered base still protrudes about half of the plate and takes over the leadership of the second worktop. The second worktop is then screwed to the second body, the plates fit tightly. Subsequently, a tension can be performed by the operation of the pulling mechanism.
