Abstract
Description
Technical field
[0001] The invention relates to a handy device for applying targeted pressure to the sole of the foot, in particular to muscles, fascia, and the arch of the foot. It serves to relieve tension, promote blood circulation, and improve foot mobility. Object of the invention
[0002] The goal is to create a small, ergonomic and hygienic foot trigger device that: • enables an even pressure distribution, • does not slip or roll away during use, • stabilizes itself through its shape, • manages entirely without additional parts such as brackets, knobs or plates, • and is easy to clean and durable. Solution to problem 1. Four-sided (tetrakelic) shape with central pressure zone
[0003] The body has a symmetrical, four-armed shape with soft curves. From above, it resembles a symmetrical cross. The center is gently curved upwards, so that when pressed, even pressure is applied to the sole of the foot. The curves flow seamlessly into one another – without any sharp edges or transitions. The body is identical in construction all around and can be used in any orientation.
[0004] The central pressure surface distributes the force evenly to the four outer edges. No bumps, grooves, or extra supports are needed – the surface remains smooth and uniform. 2. Stability and contact area
[0005] The underside is completely smooth and flat, or slightly convex. There are no indentations or concave surfaces. This ensures the device sits stably on the floor and doesn't roll away. The height-to-width ratio is approximately 1:2, providing a compact and secure base. 3. Material properties
[0006] The FlexTrigger is made of an elastic, preferably silicone-based material. It is soft yet dimensionally stable, easily compressible, and quickly returns to its original shape. This so-called viscoelastic resilience ensures that pressure is gently cushioned and evenly distributed. The material has a slightly adhesive surface that prevents slipping without feeling sticky. The material absorbs pressure, temporarily stores energy, and then releases it in a controlled manner. Harder or more plastic materials (e.g., TPE or EVA) do not achieve this effect to the same extent. 4. Interaction of form and material
[0007] The combination of its four-armed shape and elastic material creates natural stabilization at at least three points. The device stands firmly, does not tip over, and remains in place during use. 5. One-piece, hygienic design
[0008] The device consists of a single, seamless piece – without glue, joints, or inserts. This prevents dirt from penetrating and makes the device easy to wash or disinfect. 6. No additional parts
[0009] The FlexTrigger™ requires no additional supports, suction cups, handles, or mounting plates. Its stability comes solely from its shape and material. This makes it durable, easy to manufacture, and exceptionally hygienic. 7. Optional surface
[0010] Depending on the variant, the top surface may have a very fine, matte microstructure to improve grip on the skin. The underside always remains completely smooth. Mode of action
[0011] During use, the FlexTrigger is placed under the sole of the foot and light body weight is applied. Its shape automatically aligns itself, preventing it from tipping or rolling away. The material cushions the pressure, distributing it evenly and thus stimulating muscles and fascia. The device can be used barefoot or with thin socks. Differentiation from the state of the art
[0012] Other foot massagers often consist of rollers, balls, or parts with knobs that can easily slip during use. In contrast, the FlexTrigger is a compact, one-piece device that remains stable thanks to its special shape and material. It requires no supports or handles and achieves even pressure distribution without any moving parts. Advantages of the invention • Uniform pressure without pressure spikes • High stability and anti-roll effect • No slipping due to material adhesion • Gentle, elastic pressure transmission • Hygienic, robust and easy to clean • Easy to use in any position • No additional assembly or accessories required
