Description

Technical field

[0001] The invention relates to a magnetic quick-release device for fishing accessories, in particular for the detachable attachment of bite alarms, rod holders, or similar fishing equipment to banksticks, rod pods, or comparable mounts. The device enables quick connection and separation of two coupling parts by means of magnetic holding force while simultaneously providing a twist-proof connection. State of the art

[0002] Magnetic quick-release devices for fishing tackle are known. These typically comprise two coupling parts held axially together by magnetic forces. Mechanical anti-rotation devices are known to prevent rotation between the coupling parts. Known devices usually have a central magnetic connection, with anti-rotation elements arranged radially inside or outside the magnetic area. The anti-rotation elements can be formed, for example, by polygonal projections, fits, or other geometric structures that interact with corresponding structures on the other coupling part. Backlash-free designs are also known. However, in known devices, the anti-rotation element is typically located outside the central magnetic area or requires additional radial space.This often leads to situations where only limited magnet diameters are achievable with a compact design, or where the overall size of the device has to be increased. Further development compared to previous designs

[0003] A magnetic quick-release device by the same inventor is known from earlier patent application EP33043EP. This device also comprises a magnetic connection between two coupling parts with a mechanical anti-rotation device. In the known device, the anti-rotation device is achieved by a polygonal or angular projection of a guide pin that engages in a corresponding receptacle.

[0004] The present invention differs from this in particular in that • The anti-rotation mechanism is achieved by several projections arranged around a central guide pin, • the projections have sloping flanks, • the guide pin essentially serves for centering, • The anti-rotation device is provided by a structure arranged around the guide pin. The present invention represents an independent technical solution for the anti-rotation locking of magnetic quick-release devices. Object of the invention

[0005] The invention is based on the objective of providing a magnetic quick-release device, • which enables reliable rotational locking, • which allows for a compact design, • which enables a high magnetic holding force, • which ensures reliable centering of the coupling parts. Solution to the task

[0006] The problem is solved by a magnetic quick-release device having the features of claim 1.

[0007] The device comprises two coupling parts held axially together by magnets. A first coupling part has a centrally located guide pin that engages in a corresponding recess of the second coupling part. Several positive-locking projections are arranged around the guide pin, interacting with corresponding recesses in the other coupling part. The projections have angled flanks that, when engaged, inhibit or prevent rotation between the coupling parts. The magnets generate an axial clamping force that holds the projections in engagement. The anti-rotation elements are located within the central magnet area. This allows for a comparatively large magnet diameter in a compact design. This enables a high magnetic holding force while maintaining the small size of the quick-release device.At the same time, a coaxial arrangement of magnet and anti-rotation device is achieved, ensuring uniform power transmission. Preferred embodiment

[0008] Preferably, at least one of the coupling parts has a magnet with a central through-hole. The guide pin and the projections are arranged within this through-hole. This results in a coaxial arrangement of the magnet and the anti-rotation contour. The guide pin preferably serves primarily to center the coupling parts, while the projections provide anti-rotation protection. The projections are preferably arranged concentrically to the guide pin. The flanks of the projections are preferably inclined. The flanks can have any angle and, in particular, can be designed such that: • a twisting is completely prevented or • a twisting is only possible with a predetermined torque.

[0009] The projections can have any geometric shape.

[0010] In particular, the projections can: • straight contours, • polygonal contours, • curved contours, • exhibit arc-shaped contours. Brief description of the drawings
