AI Technical Summary
Existing facade construction methods require two people to precisely align and fasten boards, and commonly used tools are inflexible or insecure during nailing, leading to errors and operator fatigue.
A device with a mechanical remote transmission system, ergonomic handle, and adjustable clamping mechanism that allows one-person precise alignment and fixation of facade boards, using a bicycle brake lever to activate a wire rope for secure clamping and adjustable stops for varying dimensions.
Enables precise, ergonomic, and efficient one-person assembly of facade boards with reduced errors and fatigue, ensuring secure fixation during nailing or screwing.

Abstract
Description
[0001] Technical field: The invention relates to a hand-held assembly aid for facade construction, in particular for the construction of vertical timber board-and-batten cladding. The device serves to hold, align, and precisely position boards on a substructure by a single operator.
[0002] State of the art: The assembly of decking boards is typically carried out by manually marking out the dimensions of the boards. Precisely aligning a board during fastening usually requires two people. Commonly used tools are often inflexible or do not allow for secure vertical fixation during the nailing process.
[0003] Problem statement: The invention is based on the objective of creating a device that enables precise one-man assembly, eliminates errors caused by direct measurement transfer from the neighboring board, and allows fatigue-free operation through ergonomic components. Solution to the problem
[0004] The task is solved by a device that combines mechanical remote transmission of the clamping force and variable distance setting in a compact unit.
[0005] The base body (10) serves as a central guide rail. At its rear end, an ergonomically designed handle (25) with a bicycle grip (26) is arranged. The special feature lies in the integration of a hand lever (20) on the handle, which is preferably designed as a standard bicycle brake lever. Actuation of this lever activates a traction element (50) guided inside the base body – a wire rope within a brass tube (51).
[0006] The casing (50) is supported at a fixed point on the base body, while the tensioning element (51) transmits the tensile force directly to a movable clamping jaw (21). This clamping jaw is moved axially towards the fixed clamping jaw (22) against the force of a return element (52) (compression spring). This securely fixes a facade board located between the jaws, while the operating hand remains on the handle.
[0007] Additionally, the device has a right-angled projecting crossbar (30). A distance stop (22) is mounted on this crossbar and can be continuously adjusted to the desired flange dimension together with the distance stop (31) via a locking screw, as can (32). An integrated width adjustment (40) on the front part of the mount also allows adaptation to different material thicknesses of the boards to be mounted.
[0008] This design allows the operator to grip the board with one hand, align it using the stop on the reference board, fix it by pulling a lever, and immediately use the free hand to fasten it (e.g., by nailing or screwing). Brief description of the drawings: • Fig. Figure 1 shows a perspective overall view of the device with all its main components. • Fig. Figure 2 shows a top view to illustrate the axial alignment and the distance stop. • Fig. Figure 3 shows a side view to illustrate the arrangement of the lever and clamping mechanism. • Fig. Figure 4 shows a detailed view of the mechanical transmission unit without the base body. • Fig. Figure 5 shows the device in practical use on a facade construction in a top view.
