Description

The The invention relates to a massage slide for use in a Massage chair, a massage table or the like, along a frame in the massage chair is movable back and forth, with a drive unit, a movable by the drive unit first axis and a by. the drive unit movable second axis, one, preferably two each connected to the first axis and by the first Axis movable first arms, each arranged on a massage element is, and one, preferably two connected to the second axis and second arms movable by the second axis, each of which One on one of the first companies attacks, so that the massage elements in installation position in the frame by the drive unit with a parallel to the frame and a component perpendicular to the frame are movable, with the second arms at a distance in which they are each between the junction with the second axis and the attack site along extend, longitudinally variable are. The invention further relates to a massage unit with the Massage carriage.

Such massage slides can be designed to allow, for example, eccentric bearings, possible bends of the axes and the like complex movements of the massage elements in the form of kneading and / or knocking. For this purpose, one-armed massage slides with a first arm and massage elements or multi-arm massage slides with two or more first, the massage elements supporting arms may be provided. In the case of a spinal massage usually two-armed massage slides are provided which attack the longitudinal procedure along the spine on both sides of the same massaging. This becomes more detailed in the example DE 20 2004 003 067 U shown. The DE 20 2004 003 067 U discloses a generic complex constructed massage slide, in which the frame is mechanically loaded for functionally correct operation, which in turn must be designed according to stable.

In WO97 / 37627 also discloses a massage slide, the especially in the installation position horizontal direction relatively expansive is trained.

Of the The present invention is based on the object, a massage slide of the type mentioned in such a way that he, in the frame arranged, the same less mechanically loaded and that he still is compact.

The Asked object is inventively achieved in that at least one motor drive is provided, by means of which the distance between the second arms can be changed longitudinally is.

Since the drive is provided as part of the massage slide, the forces for longitudinal change of the distance can not from the outside, such as in the DE 20 2004 003 067 U provided, introduced by attached to the frame actuators under mechanical stress of the frame, but are generated in the massage slide regardless of the frame, so that the frame must be correspondingly less mechanically loaded and designed accordingly less stable and made of, for example, plastic, especially as an injection molded piece can be. Thus, those in the DE 20 2004 003 067 U vorgese hen actuators superfluous, which are localized or, for changing their positioning on the frame, for example, via an additional device displaceable or displaceable.

In the prior art, the change in length of the distance takes place with respect to the massage slide from the outside. When massage carriage according to the invention, the change in distance takes place by means of its associated drive self-propelled or self-propelled. Thus, the massage slide is thanks to the motor drive compared to for example one in the DE 20 2004 003 067 U disclosed spring arrangement self-moving or self-active. By means of corresponding control and / or regulating processes of the drive described further below, additional additional massage functions and / or types described by way of example below can be achieved, thereby permitting a targeted massage. Thus, in each phase, this movement can be controlled or regulated in terms of speed, paths or path sections, timings, such as clocked or, for example, accelerated motion, a contact force (eg, termination of over-massage). Thus, for example, an extremely slow change of the distance with a correspondingly slow movement of the massage elements to activate the vertebrae of a user or a quick, rhythmic change can take place, which can act as a knocking massage.

The drive itself can be any drive, such as an electromotive, hydraulic or pneumatic drive, by means of which a corresponding change in length of the distance is made possible. About the change in length of the distance and thus, as shown in detail in particular in the description of the figure, about a possible change in length of the second arms of each associated massage elements carrying the first arm can be pivoted, whereby the Massage elements can be moved over a positioning. The possible construction of the massage elements, their arrangement on the first arms, the attack of one of the second arms on an associated first arm, the eccentric mounting of the arms, the symmetrical construction of the massage slide and the drive unit are described in detail in US Pat DE 20 2004 003 067 U described, the disclosure of which is expressly included in the disclosure of this description.
