The invention relates to a device for transmitting stretching forces to a body of a person, with a bed for at least the upper body of the person, the bed being displaceable between a lying position and a stretching position and with a vibration-generating stretching drive which a foot holder for initiating the Stretching forces are assigned to the body, the bed being arranged below the foot holder in the stretched position for receiving the head of the body.

Such a device, namely a stretching device for medical gymnastics with a holder for the feet of a patient and a lifting device with which the height of the holder can be changed such that a patient connected to the holder can be transferred from a sitting or lying position to an upside-down position is known from DE 10 2005 020 667 A1. With the use of this device, the spine and the circulation can be relieved, the outflow of venous blood from the legs, the pelvis, the pelvic abdomen, in particular the liver and the spleen, being facilitated. Furthermore, the arteries in the neck are expanded. This leads 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. This also relieves the spine, but a stronger therapeutic effect for this area of the body would be desirable.

An office armchair with similar features is shown in WO 2011/044602 A1. This also has the disadvantage that the treatment is carried out with the body not stretched, which prevents the desired treatment success for the entire spine.

2.19

The same applies to a device known from DE 9310897 U1, in which the legs are bent relative to the trunk during the treatment, or treatment is only possible when the body is stretched.

Various stretch beds are also known from US 3,441,014 A, JP 2009 050 567 A1 and US 2005/0010145 A1.

The invention is therefore based on the object of providing a device of the type described at the outset, with which a stretched body can advantageously be stretched in such a way that an improved therapeutic effect for the body, in particular for the spine, can be achieved. Tensions in the spine should be released gently.

The invention solves this problem in that the foot holder comprises two foot mounts, each foot mounts separately in a guide that extends in the direction of extension, and each foot mounts can be displaced in the direction of extension with a traction device and that the bed is at least in one bed level is mounted to vibrate.

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 lying stretched on the device with its own foot holder. Stretching forces can be applied to both legs simultaneously or out of phase. So that the desired therapeutic effect for the body is achieved, the bed on which the body lies during the treatment is mounted so that it can vibrate. This not only introduces stretching forces into the spine, but also exposes them to desired transverse forces, which can help to relieve tension. The bed is supported so that it can vibrate at least in one bed level, but can also be able to vibrate perpendicularly to the bed surface in certain areas.

3.19

In order to be able to safely move the bed between the lying position and a stretching position, the bed can be mounted so that it can vibrate, which in turn is fastened to a frame so as to be pivotable about a transverse axis for displacement between the lying position and the stretching position. With this electric swivel drive, for example, any desired stretching position can be reached from the lying position, for which purpose the carrier with the bed and the foot holder is pivoted about the transverse axis by the required amount, for example by 0 to 90 °. In the stretched position, the body lies or hangs upside down in the device.

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

In order to be able to carry out the desired vibration-capable storage of the bed in a structurally simple manner, it is recommended if the bed is fastened to the carrier with attachment means which engage on the one hand on the bed and on the other side on the support, the attachment means preferably being chains, ropes or rubber-elastic profiles. These slinging devices guide the body weight resting on the bed securely into the carrier and ensure in a simple manner that the bed is mounted so that it can vibrate at least in one bed level, here on a spherical cap. This allows the bed to swing freely or damped in all possible directions on a spherical segment.

Preferably, the stretching drive comprises two rotatably driven cranks assigned to a motor mount, each of which is connected to a foot bracket via first traction means, one at one end on a crank pin and at the other end on a foot bracket, for lifting the foot bracket against the same or in opposite directions

4.19

Gravity, attack. The two cranks can be rigidly connected to one another with the drive. It is also possible to provide a gearbox between them for adjusting the angle of rotation or to equip each crank with its own drive. The motor mount is a profile assigned to the foot holder, on which in particular the drive of the cranks, in particular an electric motor with a flanged gear, is arranged.

In order to reduce the required drive power, a second traction means, with the traction direction opposite to the first traction means, can act on the crank pin, the second traction means being fastened to the motor mount elsewhere under spring pretension. Ideally, the mean spring preload to be applied via a crank revolution would correspond to the stretching force to be applied, ie if the crank drive force were in a central position of the crank pin, the average crank drive force would be zero.

The drive of the cranks is preferably fastened to a motor mount arranged on the foot holder. If the drive, an electric motor with a possibly flanged gearbox, is attached to the foot holder, then the length of the device can be easily adapted to a body size of a person to be treated, without having to make a length adjustment in the traction means. The foot bracket thus forms, among other things, the drive, cranks, traction centers and associated deflections, guides and foot mounts, an independent assembly that is fastened to the support in various positions.

The crank pin can be arranged next to a circular disk-shaped crank web, around which a brake belt is wound, which can be acted upon by a braking force in the pulling direction and in particular is under spring tension. This serves in particular to relieve play and protect the transmission, helps to avoid noise during a load change and ensures a corresponding braking force when the drive is switched off.

To support the therapeutic effect, the bed can be equipped with a heating device. This can be an electrical heater integrated into the bed

5/19 as well as any air outlets for warm air at the appropriate points.

It is advantageous if each foot receptacle can be acted upon with a restoring force, in particular with a restoring spring, opposite to the direction of extension. A treatment of a horizontally lying body is also possible so that a restoring force, in particular a spring or a weight, can be applied to the foot receptacles. The body fixed in the foot mounts can thus also be subjected to a compressive and stretching movement in a lying position, as a result of the tensile and compressive forces acting on it via the foot mounts and by means of the oscillating mounting of the bed. This represents the form of treatment with the least strain on the body, as can be used, for example, to start a treatment or for old or frail people. Every additional degree of inclination increases the intensity of the treatment. If, from a certain angle of inclination, the force of gravity against the direction of pull is large enough, the restoring force can optionally be set to zero using a suitable mechanism.

In order to prevent the position of the bed from shifting away from the foot supports due to its own weight with increasing inclination, which limits the ability of the bed to oscillate, it is proposed that the bed and the carrier be assigned a weight compensation in the form of a two-armed lever , whose first end hinges on the bed, the pivot between the two arms is rotatably mounted on the carrier and the second end at least one balance weight listens. The weight compensation balances the weight of the body support depending on the respective angular position of the bed (horizontal to vertical) and leads it back to a neutral position, from which vibration amplitudes of the same size are possible.

Preferably, handles are provided on both sides of the bed on the support or on the motor mount, projecting beyond the bed surface of the bed, preferably at least one handle for controlling at least one control device for the device

6/19 device is assigned. The function of the handles is to provide a feeling of security, especially for frail people or newcomers to this form of therapy. This special arrangement of handles and the control unit also enables the device to be operated without outside help, since the control elements are close to the handle.

The device for transmitting stretching forces Fs to a body 1 of a person includes, among other things, a bed 2 for at least the upper body of the person. The bed 2 can be moved between a lying position (FIG. 1) and a stretching position (FIG. 2). The person lies down on the couch 2 for treatment in the lying position and straps the legs with suitable cuffs or straps on a foot holder 3. In order to be able to stretch the body in a targeted and dosed manner after the couch has been moved into the stretching position, a vibration-generating stretching drive 4 is assigned to the foot bracket 3, the stretching forces (Fs) being introduced into the body 1 via the foot bracket 3, the couch 2 to take up the head of the body 1 in the stretched position below a foot holder of the foot holder 3.

According to the invention, the foot holder 3 comprises two foot receptacles 5, 6, which are mounted in separate guides 7, 8 running in the direction of extension, each foot receptacle 5, 6 being displaceable in the direction of extension with a traction means 9, 10 and that the bed 2 is at least in one lying plane 11 vibrationally mounted

Is 7/19. 4 it is indicated that the bed 2 can oscillate freely or damped about an axis perpendicular to the bed plane, depending on the mounting. Each foot receptacle 5, 6 can be acted upon in the opposite direction to the stretching direction with a restoring force, in particular with a restoring spring 27.

For this purpose, the bed 2 is mounted such that it can vibrate on a support 12, which in turn is attached to a frame 14 so as to be pivotable about a transverse axis 13 for displacement between the lying position and the extended position, optionally with a swivel drive (not shown). The transverse axis 13 extends laterally through a vertical axis of the person 1.

The foot holder 3 is attached to the support 12 so that it can be adapted to different body sizes. For this purpose, the foot holder 3 is guided with a profile 15 in a direction parallel to the direction of stretching, in particular along a guide means, namely a guide profile 16, and can be fixed in different insertion lengths by means of a bolt.

The couch 2 is attached to the carrier 12 with stop means 17 which on the one hand engage via an L-shaped stop on the couch 2 and on the other hand via an opposite L-shaped stop on the carrier 12, the stop means 17 in the exemplary embodiment being rubber-elastic profiles or in rubber-elastic hoses guided traction means, such as chains or ropes. Rubber-elastic hoses serve in particular as spacers. Said abutment means 17 absorb tensile forces but allow free or appropriately damped oscillation in the direction of any transverse forces acting on them, which in a simple manner enables oscillating support of the couch 2 about an axis perpendicular to the couch plane.

The stretching drive 4 also comprises two rotatably driven cranks 18, each of which is connected to a foot support 5, 6 via first traction means 9, 10, one at one end on a crank pin 19 and the other at a foot support 5, 6, for lifting in the same or opposite direction of the foot mounts 5, 6 against gravity.

8.19

In addition, a second pulling means 20 engages on the crank pin 19, with the pulling direction being opposite to the first pulling means 9, 10, the second pulling means 20 being pretensioned by a spring 21 attached to the carrier 12 at another end.

The drive 22 of the cranks, an electric motor with a flanged gear, is arranged on the foot bracket 3, in the exemplary embodiment on a second profile parallel to the profile 15, the motor mount 25, with which the entire extension drive is fastened to the foot bracket 3 and can be easily adapted the length of the device to a body size of a person to be treated.

A crank disk 23 in the form of a circular disk is arranged next to the crank pin 18, around which a brake belt 24 is wound, which can be acted upon by a braking force in the pulling direction Fz and in particular is under spring tension. In order to enable a simple change between lifting the foot mounts (5, 6) in the same or opposite direction, the two cranks can be pivoted relative to one another about the crank axis with a suitable drive or gear. In the exemplary embodiment, the crank pin 19 can be repositioned on the crank arm 23 by means of a screw connection, as is indicated, for example, in FIG. 1, where a screw hole in the crank arm 23 is indicated at the point diametrically opposite the crank pin 19. In this way, various strokes of the crank pins can also be set by inserting them into a screw hole which is arranged on a desired radius to the crank axis.

On both sides of the bed 2, handles 26 engaging on the bed 2 itself, on the support 12 or on the motor mount 25 and projecting beyond the lying surface of the bed can be provided, with at least one handle 26 possibly being assigned at least one control device for controlling the device.

FIG. 6 shows a weight balance for the bed in order to avoid the position of the bed shifting away from the foot mounts due to its own weight with increasing inclination. Therefore, it is provided that the bed 2 and the support 12 receive a weight compensation in the form of a two-armed lever 28

9/19 is arranged, the first end 29 articulatedly engages on the bed 2, the pivot point 30 is rotatably mounted on the support 12 between the two arms and the second end 31 belongs to at least one counterweight 32.
