Description

The invention relates to a clamping device for tool-free mounting of a solar module. STATE OF THE ART Solar panels are usually installed on roofs or other large surfaces. Especially on flat or pitched roofs, a substructure is used that is connected to the roof surface. The solar panels, as well as the substructure, must be secured against wind suction. This often proves difficult, as additional mounting tools must be carried along. Furthermore, handling mounting tools on the roof surface is often very challenging. Damage to the solar panels is not uncommon in the process. The DE 10 2012 206 166 A1 This describes a clamping device for securing a solar module. The solar modules are clamped by tightening screws. Improper tightening or incorrect torque setting can damage the solar module. In the DE 10 2025 202 596 B3 Another clamping device for mounting a solar module is described. By screwing it onto the supporting substrate, the clamping device's edge-gripping sections are closed, thus securing the solar module. The DE 20 2009 003 667 U1 This describes a generic clamping device for clamping and fixing a solar module. The solar module is gripped at its edge by a fastening element and secured against lifting by the counterforce of a threaded plate that can be attached to the substructure and tightened with a screw. Here too, the use of a tool is required to tighten the screw. TASK STATEMENT The present invention is based on the objective of creating a clamping device that can be handled without aids or tools. This problem is solved by a clamping device according to the proposed claim 1. Further advantageous details and embodiments of the invention, as well as further developments and variants, can be seen from the dependent claims and the drawing explained below. ADVANTAGES OF THE INVENTION According to the invention, a clamping device for tool-free mounting of a solar module on a mounting profile of a substructure is proposed, which has a fastener that engages the solar module at its edge and an anchoring element that is movable up and down relative to the fastener, engages in the mounting profile and clamps itself therein. The invention is characterized in that the anchoring element is penetrated by a pull pin which has a driver at its free end which, by its lifting movement, lifts and at least partially spreads the anchoring element, wherein the lifting movement of the pull pin is derived from the position of a tiltable clamping lever which has an axle body in which the pull pin is received with its other end and wherein the axle body of the clamping lever is surrounded by an eccentric which is rotatable around the axle body, wherein it exerts pressure on the fastener with its circumferential surface and thereby presses it onto the edge of the solar module. The invention allows for assembly without tools or other aids. Windproof fixing is achieved via a clamping mechanism that is manually activated by tilting a clamping lever from an inactive position to a clamping position, thereby securing the respective solar element. Preferably, the anchoring element is a hollow profile with a bottom open by a gap extending along the profile length. This bottom has two opposing, flexible fingers pointing away from the bottom, each with a hook at its free end. On the one hand, the anchoring element can be easily pressed into a mounting profile open at its apex by pushing the flexible fingers back and moving them towards each other. Once the hooks engage the mounting profile, they snap back into their initial position and engage behind it. The lifting motion of the driver pushes the fingers and their hooks outwards beyond their initial position, thus imposing vertical and transverse counterforces on the fingers, which they transmit to the mounting profile. For this purpose, the anchoring element has at least one chamber in which the driver is received. The inner walls of the anchoring element narrow the cross-section of the chamber by forming steps and conical surfaces. upon which the driver strikes during a lifting movement. This is supported by the fact that the driver is at least partially designed as a cone with shoulders arranged at the edges, which interact with the heels and conical surfaces in the anchoring element. Tool-free assembly is further facilitated by the fact that the eccentric is formed by tabs molded onto the clamping lever and separated from each other by a slot. These tabs are intersected by bearing bores for receiving the axle body, the axis of which forms the pivot point of the clamping lever, offset from the center axis of the tabs. During the tilting movement of the clamping lever, the circumferential surface of the tabs passes through the eccentric track, and the bearing bores in the tabs rotate around the axle body. This triggers a lifting motion for the axle body and the pull pin screwed into it, with its end-mounted drive pin, which in turn produces the clamping effects described above. Metall
