Description

The invention relates to a treadmill, in particular a therapeutic treadmill

Short running band, with a running surface and an endless belt guided around two deflection rollers or rollers, preferably driven by a motor.

Treadmills of the type mentioned are well known from the prior art, these usually have only one from the front to be taken handrail. They usually lack a mature backup of the trainees in case of dangerous falls during training. However, there are already treadmills that hold the trainers from above in the shoulder area or in the hip area. For this purpose, elaborate attachment means on the ceiling over the treadmill or a suspension rack are necessary to secure the trainees. In addition, the known fuses from above can hinder the trainee in training mode or even injure in the event of a fall.

It is therefore an object of the present invention to provide a treadmill of the type mentioned, which offers the trainee better security. In a treadmill of the type mentioned above, this object is achieved in that means are provided with the ability to derive the force exerted by the exerciser weight to secure in the event of a fall down, that the means securing elements for securing the hip and / or pelvis of the Have exercising within a predetermined securing area, and that the hip and / or the pelvis is free and / or muted movable within the security area.

The peculiarity of the invention over known from the prior art treadmills is securing the trainees from below, whereby its freedom of movement is increased. In addition, in the treadmill according to the invention on elaborate frame or

Wall constructions are omitted for user protection. Another advantage arises from the possibility of free and / or damped

Movement within the security area, because only in the actual case of a fall is the exercising person through the

Secured security elements. In addition, the size of the

The security area can be changed and thus adapted to the individual needs of the trainees; he is thus predeterminable. For a trainee in the early stages of his training is the

Fuse area chosen smaller to protect it from falling. For the persons who have reached a higher degree of training progress, the safety area can be increased. A damped movement gives the advantage that strong shocks on the edges of the

Secured area, whereby the exerciser is protected from a strong impact. This is particularly useful for the elderly who suffer from osteoporosis or for people who have suffered injuries in several parts of the body in an accident. In a particular embodiment of the treadmill according to the invention The attenuation increases the closer the trainee approaches the edges of the safety area. That is, the closer the trainee gets to an edge area, the stronger the damping of the movement becomes. At the edge of the security area, the movement is completely blocked so that the hip and / or pelvis can not leave the security area.

In the context of the invention, it is particularly advantageous if the means for securing against falls in the hip area or in the pelvic area of the

Immediately attack exercisers. This gives the trainee a particularly safe feeling while running or walking. In addition, this ensures a high degree of freedom of movement of the extremities of the user.

In particular, the arms, but also the legs can due to the

Support of the exerciser or user during exercise are moved freely. It is also preferable if the securing area is a linear securing area or a surface securing area or a volume securing area. This allows defined movements of the hip or pelvis. On the other hand, given movements of the hip or the pelvis can be blocked if they have a negative effect on the healing process in certain types of injuries.

In order to provide in particular a compensating movement for the hip or for the pelvis, it has proven to be preferred if the area securing area by a paraboloid or a

Kugelkalottenoberfläche or a polygon, preferably formed by a circle. This ensures that sufficient freedom of movement is provided for the trainee in the hip and pelvic area.

It is also useful if the volume securing area is formed by a polyhedron, preferably by a cuboid or a cube. By this a very large area is provided, in which the pelvis and / or the hip of the exerciser can move freely and / or muted. To face a polyhedron as

Volume control range to reduce the number of edges at which a trainee or a patient could encounter, it has proven to be useful if the volume securing area is formed by an ellipsoid, preferably by a ball.

In a particular, advantageous embodiment is by the

Securing elements of the means ensures a floating storage of the hip and / or pelvis of the trainees, so that it has sufficient freedom of movement to when walking or when

Relearning the Going, Not To Be Restricted.

It is also favorable if the securing elements of the means have at least one spring element for the elastic and / or damped mounting of the hip and / or the pelvis of the exerciser. These spring elements are particularly suited to a damped movement within the

To provide security area for the trainee, which ensures a complete blockage of the movement when reaching the edges of the security area.

Furthermore, it is advantageous if a frame is provided, which

preferably between the upper run and the lower run of the Endlosbandes is performed and which are preferably associated with the means for securing the trainees in the event of a fall. This is a particularly compact way to attach the means on the treadmill, without this having unnecessarily large dimensions. In addition, the treadmill can be formed very short because of a complex handrail or lifting construction, for example on the

Front of the treadmill can be dispensed with. It is thus possible that the length of the treadmill of the step size of

training person corresponds. It is also advantageous if the means are formed as a support rod securing the trainee. The rigid version of

Safety means as a support rod increases besides the stability of the

Securing means also subjective sense of security of the exerciser.

It is also preferred if the support rod is provided several times, preferably exactly twice. By several points of attack on the trainer this is additionally secured. In addition, the weight is distributed to more than one support rod, so that each support rod carries only a portion of the total down to be derived weight force.

In order to provide a greater freedom of movement for the trainee, it has proven to be useful if each one of the support rods are arranged on the left and right sides of the tread, preferably at least in the vicinity of the central transverse axis of the tread.

Another advantage is when the support rods a

Support device is provided for supporting the hip and / or pelvis of the trainees located between the support bars. These Support device catches the trainee in the event of a fall, without this incurs greater injuries or injuries during the collection process.

In addition, it is preferred if the support device is connected to the support rods in each case via at least one joint having a degree of freedom. This increases the freedom of movement of the

Support device secured trainees.

It is advantageous if the support device is a lowered

Seat system and / or belt system has. This also creates an increased security function for the trainee.

It is also useful if the support rods are preferably connected to the frame by an elastic lower part as part of the securing elements. As a result, the up and down movement, which a trainee while running or walking in the hips performs by the support rods is not affected. This elastic base can also cushion the pelvis.

It has proven to be preferred when the elastic lower part is formed as a upright position of the user captive biasing device. So patients can also use the treadmill, which still have difficulty with their balance, as they through the

Pretensioner be pressed in an upright position.

In order not to restrict the freedom of movement of the exerciser, it has proven to be preferred if the support rods are formed tiltable, and preferably have two degrees of translational freedom. It is advantageous if a limiter restricting the inclination is provided. This limiter preferably allows an angular position of up to 15 degrees, so that in case of a fall, the exerciser is intercepted by the support rods. Finally, it is also particularly advantageous if the support rod a the

Supporting rod length regulating Einsteilvorrichtung has. As a result, people of different sizes can work out with the treadmill since the length of the support bars can be varied.

In the following the invention will be explained in more detail in an embodiment shown in the drawing; it shows:

1 is a side view of the treadmill according to the invention,

2 is a schematic diagram of the linear fuse area,

Fig. 3 is a schematic diagram of the area securing area, and

4 is a schematic diagram of the volume securing area. Figures 2 to 4 each show schematic diagrams for the

Movement possibilities of the simplified illustrated as a ball hip or the pelvis 21 of a treadmill 1 according to the invention. The treadmill 1 has a tread 2 and a run around two pulleys 3

Endless band 4 on. Left and right side of the tread means 5 are provided, with the suitability exercised by the trainee

Weight for immediate securing in the event of a fall down derive. The means 5 have securing elements for securing the hip or the pelvis 21 of the exerciser within a predefinable

Backup area 22 on. The securing elements hold the hip or the pelvis 21 within the respective securing region 22. Within the securing region 22, the hip or the pelvis 21 can move freely, or, as illustrated in the example of the schematic diagrams, damped by the spring force of spring elements 26. These spring elements 26 may be coil springs, disc springs, gas springs or other known from the prior art suspensions. In FIG. 2, the securing region 22 is formed as a linear securing region 23. The hip or the pelvis 21 can perform a predetermined rectilinear motion while the movement in another direction is inhibited. In this form, so a floating storage of the hip or the pelvis 21 is possible. In FIG. 3, the securing region 22 is formed as a surface securing region 24, in the example of the schematic diagram as a polygon, in particular as a square. In the area of the square, the hip or the pelvis 21 can be moved freely by the exerciser or, as shown in the example, by being damped by spring elements 26. In FIG. 4, the securing region 22 is formed as a volume securing region 25, within which the hip or the pelvis 21 of FIG

Exercisers free, or as shown in the schematic diagram, can be moved muted.

FIG. 1 shows an embodiment of the treadmill 1 according to the invention. Here, in particular, a therapeutic short-circuit tape is shown, with the tread 2 and guided around the two pulleys 3, preferably driven by a motor endless belt 4. The treadmill 1 can also be driven by the leg movement of the trainees become. Means 5 are provided, with the ability to derive the force exerted by the exerciser weight to secure in the event of a fall down. The means 5 have securing elements for securing the hip or the pelvis 21 of the exercising person within a predefinable securing area 22. Within the fuse area 22 is the

Hip and / or the pelvis 21 free and / or muted movable. The means 5 for protection against falls attack in the embodiment directly in the pelvic region of the trainees.

On the treadmill 1, a frame 6 is provided, which is carried out between the upper run 7 and the lower run 8 of the endless belt 4 and to which the means 5 are assigned for securing in the event of a fall. The frame 6 can be connected to the frame construction of the treadmill 1 on which the deflection rollers 3 are provided. In the illustrated embodiment, the frame 6, however, shown separated from the frame structure of the guide rollers 3, since it can now be brought by moving between the upper run 7 and the lower run 8 to the desired position of the trainee. For example, it may be preferable to place the frame 6 farther back on the tread 2, i. distanced from the central transverse axis of the treadmill 1, to position. The means 5 shown here are as one of the trainees securing

Support rod 9 formed, which here several times, in the shown

Embodiment is provided exactly twice. In each case one of the support rods 9 is arranged on the left and right sides of the tread 2, in the vicinity of the central transverse axis of the tread 2. On the support rods 9 is a supporting device 10 as part of

Securing elements for carrying the pelvis of the between the Support bars 9 are provided trainees. These

Supporting device 10 is connected to the support rods 9 via a respective one

Degree of freedom exhibiting joint 14 connected and the support device 10 has a belt system. Also, this belt system is part of the security elements in the embodiment shown.

The support rods 9 each have at their upper end a coupling, which is designed in the illustrated embodiment as a lap belt coupling 35. At the trainee a lap belt 34 is secured with leg loops 36 for protection against vertical slipping. The lap belt 34 has one or more coupling pieces (not shown) for releasably securing the lap belt 34 to the lap belt coupling 35. All straps can be designed as detachable or tensionable Zuggurte and / or seat belts.

In the exemplary embodiment shown, the support device 10 connects the two support rods 9. It is also possible in an alternative embodiment that the respective one degree of freedom having joints 14 is not provided between the support rods 9 and the support device 10, but between the support device 10 and the belt system itself are, so that essentially a rotation about an axis perpendicular to the treadmill longitudinal axis is possible.

In addition, it is possible that the belt system or at the

Supporting device 10, a support is provided, which supports the abdominal area of the trainee. This may be in the form of support struts or a support plate or in any other known from the prior art manner. It can be arranged both at the front and at the sides in the areas of the upper abdomen and / or the middle abdomen of the exerciser. In some cases, the support can also support the lower abdominal area, provided that the pelvis or hip movement is not impaired by the support.

The support rods 9 are connected to the frame 6 by an elastic lower part 1 1 as part of the securing elements, which is formed as a upright position of the user captive biasing device.

The support rods 9 are formed tiltable and have shown in the

Embodiment two translational degrees of freedom. At the lower end of a tilt limiting limiter 12 is also provided, which also constitutes a part of the securing elements. Above the limiter 12 is a support rod length regulating

Adjustment device 13 is arranged.

The trainee wears the belt system with the leg loops 36 and the lap belt 34. This is by means of the coupling pieces with the respectively arranged on the support rods 9 lap belt couplings 35th connected. The support rods 9 can each tilt under stress their

elastic lower part 1 1 (here a spring, which can press the trainee in an upright position). The inclination is possible in two spatial directions up to a predetermined by the limiter 12 angle of 15 degrees. Nevertheless, a rotation of the person in the harness system trainees around the axis of the joint 14 is possible. Thus, in the exemplary embodiment shown in FIG. 1, a substantially formed by a spherical surface, more precisely by a spherical cap surface Area security area 21 within which the exerciser can move his hip or his pelvis 21 muffled.

The securing elements are thus formed in the embodiment by the combination of the belt 14 rotatable about the joints belt system, the elastic lower parts 1 1 of the tiltable support rods 9 and the inclination of the support rods 9 limiting limiter 12.
