Description

The invention relates to a portable massage device. Portable massage device with a cover, having a shape-changing contact segment for resting on a body area to be massaged, a rotating massage head and a tapping massage head, wherein the rotating massage head and the tapping massage head are arranged within the cover and are designed to cause a change in shape of the contact segment during operation.

Portable massage devices are used, for example, to massage the neck, shoulders, shoulder blades, back, hips, legs, stomach or feet and are used to relax and increase well-being.

Unlike stationary massage devices, such as permanently installed massage benches or massage chairs, portable massage devices can be used in different locations or even on the go.

The portable massage devices described in the prior art can generally only perform swinging or hammering movements. However, they cannot imitate human finger movements, in particular the kneading and pressing or tapping movements.

In the DE 20 201 101 281 U1 describes a portable massager that imitates a kneading motion. The massager described includes massage heads that rotate. Other similar massagers are described in the following documents: CN106619029 A , WO2013/181851 A1 , US2017/156975 A1 .

The aim of the present invention is to provide a portable massage device that further improves massage comfort. The massage effect should replicate the massage by a massaging person as closely as possible.

Our own research has shown that this can produce a particularly relaxing massage compared to massage devices where the rotating massage head also performs a tapping movement. In this case, the tapping movement interrupts the contact of the massage head during the rotating movement of the massage head, so the massage is not as pleasant as with a device that has two different massage heads.

According to the invention, the motor is preferably driven electrically. In this case, it is particularly preferred according to the invention if the motor is supplied with electrical energy by a battery and the battery is preferably arranged within the casing (11).

According to the invention, the portable massage device has a weight of less than 10 kg, preferably a weight of less than 5 kg, particularly preferably less than 3 kg. Our own research has shown that portable massage devices are preferred if they are light and can be easily carried by the user. Particularly when the massage device is placed on the area of the body to be massaged, it is advantageous if the massage device weighs less than 5 kg, preferably less than 3 kg, as this means that the pressure on the body is not unpleasant.
