Definitions

• the subject of the invention is a hand-held motor-driven massage device.
• the object of the invention is to provide a massage device that is advantageous over known massage devices.
• the massage device according to the invention has the advantage that it also enables the treatment of superficial fascia (superfascial) through lateral displacements. It can be used, in particular, to treat fascial tissue, more precisely: pathological crosslinks in superfascial structures (protein deposits in fascia), in order to prevent restricted movement.
• the massage device according to the invention can, through the movement of its feet, cause a displacement of the skin and the underlying fascia on and against the muscle. When the user presses the massage device against the body to be massaged, it can work slightly deeper and more strongly to the side. By applying appropriate pressure through the user's own strength, an impulse can also be transmitted into the depth of the tissue.
• the opposing sliding movements occurring side by side take place exclusively in one plane.
• the sliding movements of one foot take place along a first straight line
• the sliding movements of the other foot take place along a second straight line, wherein the first and second straight lines are parallel to each other.
• the speed of the foot movement can preferably be adjusted by the user.
• the massage device has at least three different speed levels.
• the feet are plate-like.
• the feet are preferably interchangeable with feet made of a different material and/or a different shape and/or size. If a foot is connected to another component of the massage device, in particular to a leg, via a pivot axis, the foot can preferably be detached from the other component in the area of the pivot axis and replaced with a different foot. Depending on the implementation of the axis, a screwdriver may be required for this. In a preferred embodiment, knurled screws are used so that the user can carry out the replacement without tools.
• a foot can be connected to another component of the massage device by means of a plug-in mechanism, wherein the plug-in mechanism can preferably be used by the user without tools. Such a plug-in mechanism is preferably located on a leg below a pivot axis. This way, the swivel joint is retained when the foot is replaced.
• the massager preferably includes attachments that can be attached to the feet so that the attachments can touch the body being massaged.
• the attachments can vary in size, shape, material, and/or surface structure.
• Advantageous attachment methods for the attachments include, in particular, a Velcro mechanism, clipping on, or slipping over the feet.
• Advantageous surface structures The feet or attachments have knobs, ridges, or grip.
• Advantageous materials for the feet or attachments are plastic, especially silicone.
• the feet are each attached to a leg by means of an axle pin, which forms a pivot about which the foot can tilt.
• the feet can also be tilted.
• the massage device has a crankshaft which has a centrally rotating gear via which the crankshaft can be driven by a motor.
• the massager can be held by only one hand of the user during operation. In a preferred embodiment, the massager can also be held by both hands of a user simultaneously during operation.
• the handle or handles by which the user guides the massager are designed so that the user can compensate for the counterforces resulting from the force exerted by the feet of the massager on the body to be massaged.
• the motor is preferably an electric motor, the energy source of which is preferably a battery included in the massage device.
• Figure 1 shows two feet of a massage device according to the invention and mechanical components that cause the movement of the feet according to the invention.
• the massage device comprises two feet 1a, 1b that can simultaneously touch a body to be massaged, i.e. a patient.
• the feet 1a, 1b are plate-like.
• the feet 1a, 1b are attached to legs 2a, 2b by means of pivot pins.
• the pivot pins each form a rotation axis around which the feet 1a, 1b can tilt to compensate for unevenness of the body.
• the legs 2a, 2b have and on the upper edge, each has a lateral pin that can move in a grooved guide 3a of a guide element 4a connected to the housing. Both the pin and the grooved guide 3a are designed to ensure the lowest possible wear by using low-friction materials or lubricants.
• a crankshaft 5 with a drive gear achieves an oscillating linear movement of the legs 2a, 2b, allowing the feet 1a, 1b to perform opposing sliding movements alongside one another in a plane parallel to the contacted surface of the body to be massaged.
• Two connecting rods 6a, 6b are mounted offset by 180°.
• the connecting rods 6a, 6b are aligned in grooved recesses within the legs 2a, 2b.
• the connecting rods 6a, 6b are rotatably attached to the legs and the crankshaft 5 via axle pins.
• a rotation of the crankshaft now ensures a linear movement of the legs 2a, 2b, since these are limited to linear movement by the grooved guides 3a, and the connecting rods 6a, 6b therefore convert the rotary movement of the crankshaft 5 into a corresponding linear movement.
• the opposing sliding movements of the feet 1a, 1b which occur side by side, take place exclusively in one plane.
• the sliding movements of one foot 1a take place along a first straight line
• the sliding movements of the other foot 1b take place along a second straight line, with the first and second straight lines being parallel to each other.
• crankshaft 5 In order for the crankshaft 5 to be driven by an electric motor, it has a rotating gear in the middle which can be driven via a worm gear 7.
• crankshaft mechanism offers several degrees of design freedom that allow for adaptation of the mechanism.
• Amplitude i.e., the maximum range of motion of the plates, can be controlled via the diameter of the crankshaft.
• a larger crankshaft diameter enables a larger amplitude, as the connecting rods follow this diameter within a radius of one rotation.
• all components of the illustrated mechanism are scalable in any dimension, ensuring a balance between compact installation space and mechanical stability. This is reflected, for example, in adjustable connecting rod thicknesses, foot size, or leg length.
• the lower groove guide of the guide element is preferably positioned as close to the feet as possible to minimize leverage forces on the mechanism caused by mechanical resistance from the patient's body.
• the mechanism presented is robust and also meets the requirements of cost efficiency and ease of manufacture.
