Description

The invention relates to a device for transmitting extensional forces on a body of a person, with a couch for at least the upper body of the person, wherein the couch between a reclined position and a stretched position is displaceable and with a vibration generating drive train a Fußhalterung to initiate the Stretching forces is assigned to the body, wherein the bed is arranged to the Kopfüberaufnahme of the body in the extended position below the foot bracket.

Such a device, namely a stretching device for therapeutic gymnastics with a holder for the feet of a patient and a lifting device with which the height of the holder is variable such that a connected to the holder patient from a sitting or lying position in a head-hanging position can be transferred is, is out of DE 10 2005 020 667 A1 known. With the use of this device, the spine and the circulation can be relieved, whereby the outflow of venous blood from the legs, pelvis, pelvic, especially the liver and spleen is facilitated. Furthermore, the arteries are distended in the neck. It comes to an improved blood supply to the brain through the improved oxygenation of the blood. In addition, the brain is supplied with both quantitatively and qualitatively upgraded blood. Although it is thus also achieved a relief of the spine, but a stronger therapeutic effect for this body area would be desirable.

An office chair with similar features shows the WO 2011/044602 A1 , This also has the disadvantage that the treatment is carried out in unstretched body, which prevents a desired for the entire spine treatment success. The same applies to one from the DE 9310897 U1 known device in which the legs are facing during treatment hunched over the trunk, or a treatment in a stretched body only lying is possible.

Diverse stretched beds are still from the US 3 441 014 A , of the JP 2009 050 567 A1 and the US 2005/0010145 A1 known.

The invention is thus based on the object to provide a device of the type described, with which a stretched body can be stretched so advantageous that an improved therapeutic effect for the body, in particular for the spine, can be achieved. It should be able to gently release tension in the area of the spine.

The invention solves the problem set by the fact that the foot holder comprises two foot receptacles, each foot receptacle is stored for itself in a separate, extending in the direction of extension guide, and wherein each foot with a traction means in the stretching direction is displaced and that the couch at least in a lying plane is mounted vibratory.

With such a device, a stretched body can advantageously be stretched and an improved therapeutic effect for the body, in particular for the spine, can be achieved. This is particularly because stretching forces can be introduced separately into each leg of the body which is stretched on the device with its own foot receptacle. In both legs, simultaneous or out of phase stretching forces can be initiated. In order for the desired therapeutic effect to be established for the body, the couch on which the body rests during the treatment is capable of oscillating. Thus, not only stretching forces are introduced into the spine, but also exposed to these desired transverse forces, which can help to release tension. The couch is at least capable of oscillating in a lying plane, but it can also be oscillatable in certain areas perpendicular to the lying surface.

To be able to shift the couch safely between the lying position and a stretched position, the couch can be mounted to oscillate on a support, in turn, for displacement between the lying position and the stretched position, optionally with a pivot drive, to a transverse axis pivotally mounted on a frame. With this example, electric swivel drive can be approached from the lying position any desired stretched position, including the carrier with the lounger and the foot bracket to the transverse axis by the required level, for example, by 0 to 90 °, is pivoted. In the extended position, the body lies or hangs upside down in the device.

In order to be able to adapt the device quickly with a simple construction to different body sizes, it is advantageous if the foot holder is attached to the carrier and is guided longitudinally adjustable for length adjustment in a stretching direction parallel direction preferably along a guide means. The upper body is therefore always centered on the lounger and the position of the foot shots is adjusted by adjusting the Verschublage the foot bracket with respect to the wearer.

In order to accomplish the desired oscillatory storage of the lounger constructively simple, it is recommended that the couch is fixed to the support with stop means which attack on the one hand on the couch and on the other hand on the carrier, the slings are preferably chains, ropes or rubber-elastic profiles. These slings guide the resting on the couch body weight safely in the carrier and make sure in a simple manner that the couch is at least in a lying plane, here on a spherical cap, mounted vibratory. Thus, the couch can oscillate freely or muted in all possible directions on a spherical segment.

Preferably, the stretch drive comprises two rotationally driven, an engine mount associated cranks, each of which is connected to a respective foot holder via first traction means, each at one end of a crank pin and the other on a foot bracket, for the same or opposite directions lifting the Foot mount against gravity, attack. The two cranks can be rigidly connected to each other drive. It is also possible to provide a gear between them to adjust the angle of rotation or to equip each crank with its own drive. The engine mount is a profile assigned to the foot mount, on which, in particular, the drive of the cranks, in particular an electric motor with flanged gear, is arranged.

In order to reduce the required drive power can act on the crank pin, a second traction means, with opposite to the first traction means pulling direction attack, the second traction means is fixed at the other end of the engine mount under spring tension. Ideally, the applied over a crank revolution mean spring preload would correspond to the applied yield force, the crank drive force would thus be in a center position of the crank pin, the average crank drive force, equal to zero.

The drive of the cranks is preferably fastened to a motor mount arranged on the foot mount. If the drive, an electric motor with optionally flanged gear attached to the foot mount, it is possible to easily adjust the length of the device to a height of a person to be treated, without having to make a length compensation in the traction means. The foot mount thus forms, among other things, drive, cranks, Zugmitten and associated deflections, guides and foot mounts an independent on the carrier in different positions adjustably mounted assembly.

The crank pin may be juxtaposed with a circular disk-shaped crank arm around which a brake belt is wound, which can be acted upon in the pulling direction with a braking force and in particular is under spring tension. This is used in particular to a play release and protection of the transmission, helps to avoid noise during a load change and ensures a corresponding braking force with the drive off.

To support the therapeutic effect, the couch can be equipped with a heating device. This can be an electric heater integrated into the lounger, as well as any air outlets for hot air in the appropriate places.

It is advantageous if each foot receptacle opposite to the stretching direction with a restoring force, in particular with a return spring, can be acted upon. So that the foot receptacles with a restoring force, in particular with a spring or a weight, can be acted upon, a treatment of a horizontally lying body is possible. The body fixed in the foot receptacles can thus also be exposed in a lying position, as a result of the tensile and compressive forces acting on it via the foot receptacles, and by means of the oscillatory mounting of the stretcher, an upsetting and stretching movement. This represents the least stressful form of treatment for the body, such as those that can be used to start a treatment or for old or infirm people. Each additional degree of skew increases the intensity of the treatment. If, from a certain angle of inclination, the force of gravity against the pulling direction is high enough, the restoring force can optionally be reset to zero via a suitable mechanism.

In order to avoid that the position of the couch due to its own weight with increasing inclination shifted away from the foot shots away, whereby the vibrational ability of the bed is limited, it is proposed that the couch and the carrier weight compensation is assigned in the form of a two-armed lever whose first end hingedly engages the couch, the fulcrum of which is rotatably supported between the two arms on the support and the second end of which at least one balancing weight belongs. The weight balance compensates the weight of the body support depending on the respective angle position of the couch (horizontal to vertical) and leads them back to a neutral position, from which equally large vibration amplitudes of the lounger are possible.

Preferably, on both sides of the couch on the support or on the motor carrier attacking, the lying surface of the bed superior handles provided, preferably at least one handle at least one control device is assigned to control the device. The handles have the function of providing a sense of security especially for frail people or newcomers to this type of therapy. This special arrangement of handles and the control unit also allows the device to operate without external assistance, since the controls are immediately within reach.
