Description

The invention relates to an abdominal exerciser with a movable arm unit, with a movable leg unit and with a longitudinally force-variable coupling member which is arranged between the arm unit and the leg unit.

From the EP 2 111 268 B1 For example, a abdominal exerciser including a frame having a front arm unit and a rear leg unit is known. The leg unit is designed as a carriage that can slide on a rail. The rail extends arcuately to the front arm unit, which is arranged stationary. The operator of the training device is arranged substantially upright, wherein only part of the abdominal muscles can be trained by movement of the leg unit.

From the US 2010/0216615 A1 For example, an abdominal exerciser is known which consists of a movable arm unit, a movable leg unit and a length-variable coupling member connecting the arm unit to the leg unit. By exerting a stretching force on the coupling member, the body of the operator can be brought into a stretched position. In a direction opposite to the stretching force, only a relaxing movement takes place, which raises the upper body of the operator.

Object of the present invention is to develop an abdominal training device such that in a simple and compact way many abdominal muscle areas can be trained, in particular, a continuous whole body movement of the operator is caused.

To achieve this object, the invention in conjunction with the preamble of claim 1, characterized in that the arm unit and / or the leg unit is connected via a longitudinally force-variable coupling member with a stationary holder.

According to the invention, not only the arm unit is coupled to the leg unit but also the arm unit and / or the leg unit with a stationary holder. As a result, not only a body-exercising force in a direction of movement, but in two opposite directions of movement, by reciprocation. When the operator steps on the arm and leg unit in a quadruped position, a force is applied both when the arm and leg unit contracts and when the arm and leg unit are pushed apart. It is not only the abdominal muscles, especially under stress of the abdominal muscles (straight abdominal muscles, transverse abdominal muscles, inner abdominals, outer oblique abdominal muscles), but also the secondary muscles which claim the total musculature of the body. The invention thus enables a whole-body movement or training of the whole body. The exercising operator works both over the leg lever and over the upper body lever in the abdominal musculature. In addition, the training operator works due to the horizontal position against the gravity of the body weight. The invention advantageously allows for a "multi-dimensional" stress on the body musculature with only a single form of exercise. The force-variable in the longitudinal direction or in the direction of movement coupling members allow, for example, a change in length of the same a continuous stress on the body of the operator in terms of tensile and compressive forces.

According to a development of the invention, the arm unit, the leg unit and the holder form a rectilinear row, so that in this way a straight direction of movement during contraction and stretching of the arm and leg unit is given. The rectilinear arrangement results essentially as a result of the coupling elements arranged between the said assemblies.

According to a development of the invention, the arm unit and the leg unit form a slide unit, wherein between the arm unit and the leg unit a force-variable in the longitudinal direction inner coupling member and between the carriage unit on the one hand and a first holder or second holder on the other hand in each case a longitudinally force-variable outer coupling member is arranged , Due to the preferred length variability of the inner coupling member, the carriage unit is contractible and stretchable. Due to the variable length outer coupling member can be generated with change in the relative position between the arm and leg unit, a counter force acting on the carriage unit. If the outer coupling links are not equally variable in force per path, ie if the outer coupling links, for example, do not have the same modulus of elasticity, this causes the movement of a center axis of the carriage unit in a direction of movement. If the outer coupling links have the same force variation per path, there is a periodic stretching and compressing movement about a zero line located midway between the arm and leg unit, with the carriage unit not moving since the center axis of the carriage unit is at the zero line coincides.

According to the invention, the carriage unit has a starting position in which the arm and Leg unit are arranged without force. The home position can be used to take the operator's exercise position or remove it from its exercise position. In addition, the carriage unit has a plurality of expansion positions and compression positions, wherein these positions are dependent on the expander or compression force applied by the operator.

According to a development of the invention, the outer coupling member and / or the inner coupling member are formed as a flexible band. Preferably, the outer coupling members have the same modulus of elasticity, so that a symmetrical and periodic training movement can take place about a zero line. If the emphasis is to be placed on the training of the upper body, coupled to the arm unit outer coupling member may have a greater modulus of elasticity than coupled to the leg unit further outer coupling member.

According to a development of the invention, the inner and / or the outer coupling member may be formed as a rope or as a chain. The outer coupling member may have a direction change via pulleys, where at the end acting on the carriage unit counter force of the outer coupling member is adjustable by changing a weight. The weight may for example be designed as a plug-in weight, which is commonly used in exercise equipment.

According to a development of the invention, the arm unit and the leg unit are arranged movably in the direction of movement via a longitudinal guide. Advantageously, a targeted longitudinal movement of the carriage unit is thereby predetermined, so that the exercising operator is not exposed to disturbing transverse forces.

According to a development of the invention, the longitudinal guide may be formed by running in a rail rollers, which allows the exercise device a relatively simple structure.

According to a development of the invention, the arm unit and the foot unit on support means, so that hands or forearms and feet or lower legs can be supported. In this way, the exercising operator can assume the training position without the need for additional holding means or fastening straps.

According to a development of the invention, the arm unit and / or the foot unit on vertical support means, so that the exercising operator can hold in the direction of movement and does not lose the training position.

According to a development of the invention, the carriage unit is made of a wood material or of a metal material, for example of a stainless steel material. The arm and leg unit of the carriage unit are arranged so compact and box-shaped that a comfortable support of the operator is ensured on the same.

An abdominal exerciser consists essentially of a carriage unit 1 that have a rail arrangement 2 in a direction of movement 3 between an opposite first holder 4 and a second holder 5 is movably arranged. The carriage unit 1 has an arm unit 6 for receiving an arm 7 and one hand 8th an operator 9 as well as a leg unit 10 for receiving a leg 11 or foot 12 same operator 9 on. The arm unit 6 and the control unit 10 are each box-shaped and have as support means on a top preferably a flat surface 13 respectively. 14 on, to have a forearm 7 ' of the arm 7 or a lower leg 11 ' of the leg 11 longitudinally on the surface 13 respectively. 14 can support. The surface 13 the arm unit 6 as well as the surface 14 the leg unit 10 has a width such that two poor 7 or two legs 11 the exercising operator 9 can be supported. For example, the surfaces 13 . 14 also have formations, so that ergonomically favorable forearm 7 ' or the lower leg 11 ' of the leg 11 Are safely supported positionally, without the risk of slipping in the lateral direction, ie transverse to the direction of movement 3 consists.

A length l _{1 of} the arm unit 6 is so big that the forearm 7 ' over its entire length on the surface 13 the arm unit 6 can support. The leg unit 10 has such a length l ₂ that the operator 9 with the lower leg 11 ' over the entire length of the lower leg 11 ' on the surface 14 the leg unit 10 can support.

In addition, the arm unit points 7 at a front end a still protruding handle 15 (vertical support) on which the operator with the hand 8th can hold on. The handle 15 For example, it may be formed as a U-shaped bracket extending from the surface 13 the arm unit 6 rises. The lower leg 1' of the leg 11 is so on the surface 14 the leg unit 10 positioned so that the foot 12 over a back of the surface 14 protrudes and during a movement of the leg unit 10 towards the front V against a back 16 the leg unit 10 suppressed.

Both the arm unit 6 as well as the leg unit 10 each have at least two offset from one another to the front arranged rollers 17 on that in a U-shaped rail 18 rolling are stored to form the rail assembly 2 , The rail 18 preferably extends continuously from the front first holder 4 to the rear second holder 5 , To the stability of the slide unit 1 to improve, the rail arrangement has 2 preferably two parallel mutually offset rails 18 on, in each case to the front V offset from each other arranged roles 17 the arm or leg unit 6 . 10 are stored leading. For this purpose are the roles 17 each on transverse to the direction of movement 3 extending axes of the arm unit 6 or the leg unit 10 stored. The arm unit 6 and the leg unit 10 thus each form carriages in the direction of movement 3 are reciprocable.

According to an alternative embodiment of the invention according to 5 can the rail arrangement 2 also by one between the first holder 4 and the second holder 5 extending round spar 19 be formed, on the rollers 20 the arm unit 6 or the leg unit 10 leading are stored, with the rollers 20 each having concave running surfaces.

The rail arrangement 2 thus forms a longitudinal guide of the carriage unit 1 in the direction of movement 3 , The arm unit 6 , the leg unit 10 as well as the first holder 4 and the second holder 5 are thus arranged in a straight row, wherein the arm unit 6 and the leg unit 10 in each case only to the front V or in the opposite direction to the rear are movable.

The training unit forming units "arm unit 6 "," Leg unit 10 "As well as" first holder 4 "And" second holder 5 "Are in the direction of movement 3 adjacent units connected to each other via a force-variable coupling member. The force-variable coupling member preferably extends in the direction of movement 3 , In the first embodiment according to 1 the coupling member is formed by an elastic or flexible band. A first inner coupling member K _i is at a first end to the arm unit 6 and with a second end on the leg unit 10 firmly connected. A first outer coupling member K _a1 is connected to a first end on the first holder 4 and with a second end on the arm unit 6 attached. A second outer coupling member K _a2 is at a first end to the foot unit 10 and a second end on the second holder 5 attached. The inner coupling member K _i can have the same elongation properties as the outer coupling members K _a1 , K _a2 . On the other hand, the inner coupling member K _i also have different elongation properties than the outer coupling member Kai and / or as the second outer coupling member K _a2 .

According to a preferred embodiment according to the 2a to 2c the two outer coupling members K _a1 and K _{a2 have} the same elongation properties. The outer coupling members K _a1 and K _a2 have the same elastic modulus E, which may differ from the elastic modulus E of the inner coupling member K _i . In this way it is ensured that always a symmetrical back and forth movement of the arm unit 6 and leg unit 10 is ensured when applying the training device by the exercising operator.

In an in 2a illustrated starting position of the training device, in which both the inner coupling member K _i and the outer Coupling members K _a1 , K _{a2 are} free of forces, the operator can take the training position or leave the same.

By exerting a stretching force F _D by the exercising operator 9 become the arm unit 6 and the leg unit 10 moved apart, wherein the inner coupling member K _{i is} stretched and on the arm unit 6 and the leg unit 10 an equal counterforce F _GD exercises. The outer coupling links K _a1 , K _a2 are compressed and exert no force. With increasing displacement s is the training by the operator 9 expansive force F _{D to be} increased. After reaching a turning point, the arm unit move 6 and the leg unit 10 towards each other, wherein the inner coupling member K _{i is} relaxed and the outer coupling members K _a2 , K _a2 in their initial position ( 2a ) are moved back. Due to the existing momentum of the return movement, the arm unit 6 and the leg unit 10 moved together, with the outer coupling links K _a1 and K _a2 stretch. The exercising operator 9 must now exert an upsetting force F _S , by means of which the arm unit 6 and the leg unit 10 be contracted further than in the starting position. The inner coupling member K _i is relaxed. The outer coupling links K _a1 , K _a2 are stretched and exert an equal counterforce F _GS . The carriage unit 1 is now in a compression position according to 2c ,

The carriage unit 1 is in a stretched position as soon as the arm unit 6 and the leg unit 10 from the starting position according to 2a be pulled apart. Because from this point on there is an expansion of the inner coupling member K _i . The carriage unit 1 is in a compression position as soon as the outer coupling links K _a1 , K _{a2 are} stretched, so the arm unit 6 and the leg unit 10 from the starting position according to 2a be contracted.

With the exception of the starting position is the carriage unit 1 always in a stretched or compressed position, so that the exercising operator 9 always have to exert an expansion force F _D or compression force F _S. This is a periodic reciprocation of the arm unit 6 and the leg unit 10 exercised, with increasing deflection of the arm unit 6 / Leg unit 10 from the initial position increases the force to be expended. During exercise there is a periodic movement of the arm unit 6 and the leg unit 10 around its zero position N (initial position), wherein an expansion movement alternates with an upsetting movement.

If the outer coupling members K _a1 and K _{a2 have} the same modulus of elasticity, the force required for the compression movement F _S for the arm unit 6 and the leg unit 10 equal, so a periodic movement of the arm unit 6 and the leg unit 10 around the zero line N takes place. The zero line N extends in the middle between the arm unit 6 and the leg unit 10 in the starting position of the same, wherein the same take a distance a to each other in the initial position.

For example, when the first coupling member K _a1 has a greater modulus of elasticity than the second external coupling element K _a2, the forge force expended on the arm unit 6 bigger than at the leg unit 10 so that the muscles of the arms 7 the operator 9 is trained more than that of the legs 11 the same. By adjusting the coupling links K _i K _a1 , K _a2 can thus targeted training of different muscle parts of the operator 9 be effected. For this purpose, the coupling members K _i , K _a1 , K _a2 changeable on the first holder 4 , second holder 5 and the arm unit 6 and the leg unit 10 be attached.

According to an alternative embodiment according to 5 in particular, the outer coupling members K _a1 , K _a2 also by a rope 21 be formed, whose free end with an adjustable weight 22 connected is. The rope 21 is over pulleys 23 stored so that the adjustment weight 22 in the starting position of the carriage unit 1 can be adjusted in the usual way. The weights can be designed as plug weights - as in other known training devices, the effectiveness of individual and multiple plug weights is set by inserting a rod.

According to a further embodiment of the invention, not shown, in particular the outer coupling members K _a1 , K _{a2 may} also be formed by a chain.

According to another alternative embodiment of the invention, not shown, either only the arm unit 6 or the leg unit 10 via the outer coupling member K _a1 or K _a2 with the holder 4 respectively. 5 be connected. In this embodiment, the uncoupled leg unit would 10 or arm unit 6 the carriage unit 1 free in the direction of movement 3 can move.

According to another alternative embodiment of the invention, not shown, either the arm unit 6 or the leg unit 10 via the outer coupling member K _a1 , K _a2 with the first holder 4 or second holder 5 be connected. The other unit of the sled, namely the leg unit 10 or the arm unit 6 , would be arranged stationary.

The carriage unit 1 may be made of a wood material or of a metal material, such as a stainless steel material.
