BRIEF SUMMARY
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a national phase of PCT/EP92/01029 filed 11 May 1992 and based upon German national applications P41 16 460.0 of 21 May 1991, P 41 21 416.1 of 28 Jun. 1991, P41 32 464.1 of 30 Sep. 1991 and P42 04 547.7 of 15 Feb. 1992 under the International Convention.
FIELD OF THE INVENTION
The present invention relates to a massage appliance which has a massage container and a suction pump and is provided with a handle.
BACKGROUND OF THE INVENTION
In most known massage applications which are provided with a handle, the handle is rigidly connected to the massage appliance. These massage appliances require an especially careful handling, in order to insure that the massage container stays in touch at all times and over its entire contact surface with the body of the patent. A suitable use of these massage appliances during self-treatment by the patient is therefore fraught with difficulties.
A massage appliance wherein the massage container is swingably connected to the handle is also known (FR-A-638 309). In this case only a very limited adjustment of the contact surface of the massage container to the body of the patient is possible, since the massage container performs motions only about a single axis.
There are also known massage appliances wherein the massage container is designed as a hollow body rotatably mounted on the handle, which during the massage rolls off the patient's body (DE-C-523 208 and DE-C-427 822). However, the rotatability of the massage container does not allow an adjustment of the contact surface of the massage appliance to the body of the patient.
OBJECT OF THE INVENTION
It is the object of the invention to provide an improved massage appliance which can ensure a perfect adjustment of the contact surface of the massage container to the body of the patient so that even during self-treatment by the patient no difficulties arise.
SUMMARY OF THE INVENTION
The object is achieved in an appliance wherein the massage container is rotatably and swingably connected with the handle. The massage appliance of the invention allows the massage container to move about several axes, so that independently of the hand guiding the massage appliance, the massage container remains at all times in contact with the body of the patient as long as a slight pressure is exerted on the body with the massage container.
In a development of the invention a rod is fastened to the massage container, which is rotatably supported in the handle and has a fork-like projection at its end facing the massage container, whereby the two ends of the fork-like projection engage in the swing bearing provided on the massage container, so that the massage container can swing with respect to the rod. The inner space of the massage container is in contact with the suction pump via a hose. The suction pump can consist of a manually actuatable rubber balloon. But the suction pump can also be a piston pump, an electro-vacuum pump or the like. Since the hose forms an elastic connection between the suction pump and the massage container, the movements of the massage container with respect to the handle are not impeded by the hose. The hose can constitute the only connection between the suction pump and the massage container.
In order to avoid generation of torque during the rotation and swinging motions of the massage container, according to a further feature of the invention the rotation axis of the rod and the swing axis of the massage container are both located within the same plane.
In a preferred embodiment of the invention, the rod is connected with the handle with a torsion spring, so that the rod is always returned to its basic position. The function of the torsion spring can also be taken over by the hose.
In another embodiment of the invention the upper part of the massage container is spherical and the handle is provided at is end facing the massage container with a ring or a hood with a capshaped inner wall which encloses the spherical part of the massage container.
