    BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a training mechanism in which a person mimics movements similar to crawling up a ladder, a plurality of ladder steps being distributed on a circular conveyor device having a front and a rear side, wherein the ladder steps at the front are arranged to move downward in grooves along each side of the conveyor device and whereby the ladder steps are attached to propellants all of which are in non-sliding engagement with at least one common transverse shaft.
    From US Patent No. 4,848,737, a training mechanism of this kind is known in which an electric motor moves the ladder steps by operating conveyor device. This makes the mechanism both expensive and safety it is best that exercise equipment of this kind does not contain parts that require the supply of electrical power.
    According to the invention there is provided a training machine which does not need power supply and where the speed at which the ladder steps move during a person's work in the machine is essentially independent of the person's weight.
    This is accomplished by the motion of the propellants not being transposed to rotate a brake wheel comprising brake pads which are movable in the radial direction under the influence of the centrifugal force of the applied rotation, whereby the brake pads upon radial motion come into friction against the inside of a brake wheel fixed mount. In this way, it becomes possible to make the deceleration dependent on the speed of the ladder steps and not on the weight with which they are loaded.
    As stated in claim 2, the non-skid transfer of the motion of the propellants to the brake wheel during exchange is effected so that the speed of movement of the propellants is translated into a speed of rotation of the brake pads on the brake wheel which is greater than the speed of movement of the propellants. The reaction to a greater speed of the brake pads on the brake wheel helps to ensure that a greater centrifugal force is applied to each brake pad, so that the prevention of further speed increase occurs at a well-defined speed of the ladder steps movement.
    As stated in claim 3, it is preferred that the brake surface fixedly mounted around the brake wheel comprises a bell having an inner radial brake surface for receiving the radially outward pressure from the brake pads and a disc part thereof not rotatably mounted on the same axis of the brake wheel. pivot. This design of the brake helps to ensure that the heat generated by the brake contact with the inside of the clock can be easily dissipated away from its outside.
    It is further preferred that during the rotation of the brake wheel, the centripetal force of the brake pads is absorbed by a combination of spring force and abutment force between the brake pads brake surface and the clock radial inner brake surface. The centripetal force is directed towards the center of rotation, holding the brake pads in their lane. Part of the force is supplied by a spring, and by choosing the spring end points appropriately it can be ensured that the force from the spring as a function of the movement of the brake pad outwards is appropriately regulated. Thus, it may be desirable for the spring force to decrease as the brake pad reaches beyond a given radial position, so that a greater portion of the centripetal force thereafter comes from the brake pad's abutment toward the clock radial brake surface.
    As set forth in claim 5, the propellants in the conveyor device must be moved downward along with the ladder steps of a front plane under the influence of a person's weight when the device is used. At the same time, the rear propulsion means will move upwardly, the gear mechanism being provided at the rear and comprising a first larger drive wheel coupled to the common drive shaft, the first larger drive wheel being in driving communication with a smaller drive wheel, which smaller drive wheel sits on the same shaft as the brake wheel. By this arrangement, it can be ensured that the brake and gear are kept away from the working area which the front is constituting.
    As stated in claim 6, the drive means at the rear are in drive relationship with drive wheels on the common shaft, which common shaft is arranged in a plane displaced from the front plane. This displacement of the common axis relative to the front ensures that all ladder steps not located at the front are kept at a good distance from it. After that, a guard plate is not needed behind the steps on the front, which in turn gives the user better room to put both his feet on the lower steps and with his hands to get a good grip on the upper steps.
    As stated in claim 7, it is preferred that the common shaft is provided between an upper and a lower turning wheel for each of the propellants in the face plane. This design method keeps the device simple and only a minimum of bearing parts are used.
    As stated in claim 8, there is in the front plane a front machine frame part whereby the tracks the ladder steps are controlled in are embedded in the machine frame part. This provides great stability and creates space at the rear of the rear machine frame to the front machine frame, so that the exchanges and braking arrangement can be easily established without conflicting with the front where the user must be able to work freely.
    The invention will now be explained in more detail with reference to the drawings, in which:
    FIG. 1 is a schematic 3d representation of an example of a training mechanism according to the invention,
    FIG. 2 shows an enlarged section of the training mechanism of FIG. 1 and viewed from a different angle,
    FIG. 3 shows a brake wheel,
    FIG. 4 shows a bell for mounting externally to the brake wheel,
    FIG. 5 shows a section through a portion of a front machine frame with a ladder step and,
    FIG. 6 shows a schematic 3d representation of an alternative to the example of FIG. 1 In FIG. 1 shows a training mechanism 1 and in schematic form a person who is ready to start a training session. The training consists of the person stepping up on the lower ladder stage 11, and from there moving upwards on the successive ladder stages 12, and here imitating movements corresponding to crawling up a ladder, which imitation occurs while the ladder steps downwards in the at the same rate as the person ascending on steps 11, 12. The person similarly holds hands with the upper ladder steps 15, 16. During operation, all ladder steps are moved round the conveyor device, so that a new top step is constantly gripped and a new bottom step from which the person must step up to maintain his position on the front of the training mechanism.
    The ladder steps are distributed on a conveyor device 2 having a front face 3 and a back side 4, so that the ladder steps 11-16 at the front side 3 are arranged to move downwardly in groove 5 (not shown in Fig. 1 and Fig. 2) along each side. of the conveyor device 2. of the ladder steps are attached to drive means 6, all of which are in non-sliding engagement with at least one common transverse shaft 7. In the example shown in FIG. 1 and 2, the driving means comprise a right chain 9 and a left chain 10 in which are respectively located on one and the other side of the ladder steps and attached to each ladder stage. The chain may be a plain chain similar to a motorcycle chain or it may be a toothed belt or other element capable of transferring the pull from the person moving up the ladder steps to the machine frame 17. The machine frame comprises vertical and horizontally joined profiles of durable material so like iron. The movement of the chains 9,10 or the propellants is transferred non-skid to rotation of a brake wheel 8 as seen in FIG. 2. The brake wheel 8 itself is shown in FIG. 3, and is particular in that it comprises brake pads 13 which are movable in the radial direction under the influence of the centrifugal force of the applied rotation. When the bricks 13 are pulled outwardly by the radial movement, they reach frictional engagement against the inside of a brake surface 14 mounted firmly around the brake wheel 8. Braking mechanisms of this type are known as centrifugal couplings, and are used today, for example, in smaller two-wheel motor vehicles, so that the output of the engine is connected to a brake wheel and the vehicle's axle is connected to the brake surface. When the engine reaches a certain speed, the brake pads will move outward and engage the brake surface, and the brake wheel and the movements of the brake surface are thus synchronized by further increase in the speed of the motor output shaft.
    As shown in FIG. 2, the non-skid transfer of the movement of the drive means 6 to the brake wheel 8 will occur during exchange, so that the speed of movement of the drive means 6 is translated into a speed of movement of the brake pads 13 on the brake wheel 8 which is greater than the speed of movement of the drive means 6. This turnover must, of course, be adapted to the geometry of the selected brake wheel and a spring 18 coupled to each globe. The spring 18 holds the brake pads in place at low speeds, but provides resilient at higher revolving speeds. In FIG. 2, it is seen that the brake surface fixed around the brake wheel comprises a bell 19. This is also shown in FIG. 4. The bell 19 has an inner radial brake surface 20 which can receive the radial outward pressure from the brake pads 13 and the brake surface 20 is further connected to a disc part 21 which is not rotatably mounted on an axis coinciding with the axis of rotation of the brake wheel 22. The bell is is also firmly connected to the machine frame and is thus not rotated when the brake pads of the brake wheel engage it.
    The design causes the centripetal force of the brake pads 8 during rotation of the brake wheel to be absorbed by a combination of spring force and abutment force between the brake pads brake surface and the clock radial inner brake surface 20. This ensures that even a slight increase in the number of revolutions creates a further increase in the increase in braking force.
    As the training mechanism is shown in Figs. 1 and 2, the drive means 9,10 in the conveyor device 2 will be moved downwardly along the ladder steps 11,12,15,16 at the front 3 under the influence of a person's weight 23 when the device is used. At the same time, the propellants 9,10 or the chains shown in FIG. 1 and 2 at the rear 4 are moved upwardly, the exchange mechanism being provided at the rear 4 and comprising a first larger drive wheel 24 coupled to the common shaft 7 of the propellants 9,10. The larger drive wheel 24 is in driving engagement with a smaller drive wheel, which smaller drive wheel 25 sits on the same shaft 22 as the brake wheel 8. The brake wheel 8 is not visible in FIG. 1 and 2, being inside under 19 o'clock. The connection between the larger and smaller drive wheels can be directly by tooth engagement, by chain pull, by belt pull by cardant pull, or by other rotation transmitting element.
    As further seen in FIG. 1, 2 and 6, the drive means are in the form of right chain 9 and left chain 10 in the rear in driving relationship with drive wheels on the common shaft 7, and as can be seen, shaft 7 is arranged in a plane at the rear 4 which is offset from a plan forming the front face 3. It is thereby ensured that the upward steps at the back do not get too close to the downward steps at the front when a person uses the exercise mechanism. In the illustrated example of the invention, the front together with two oblique courses of the conveyor mechanism forms a triangle, but a space-shaped or square course (shown in Fig. 6) is of course possible using several turning wheels.
    The common shaft 7 is provided between an upper and a lower turning wheel 32 for each of the propellants 9,10 in the face plane so that the ladder steps on the back side both above and below are kept away from the front side. In the embodiment shown in FIG. 6, however, the common axis 7 is positioned at the level of the upper turning wheels 32, so that the ladder steps here provide a horizontal run between the shaft 7 and the upper turning wheels 32, this construction also ensuring distance from the upward rising steps from the front. In front 3, a flat machine frame member is provided and herein the ladder steps are guided in embedded tracks 5. In FIG. 5, a plan section is shown perpendicular to a groove 5 embedded in a machine frame portion at the front face 3. Here, it is seen that the ladder stage 12 is formed as a% inch pipe 27 and that a machined machine part 28 is inserted into the pipe. Outside of the tube 27, the machine part 28 extends into a U-profile 29, and here the machine part 28 is guided by guide rails 30 inserted at the mouth of the U-profile 26. At the bottom of the U-profile, there is space for the machine part 28 to be attached to the chain. 9 so that the chain is inside the U-profile 29 as the ladder steps are pulled downward along the front of the machine frame. A square tube 31 further stabilizes the machine frame as seen in FIG. 5. The U-profile may conveniently be a 70x50x70mm profile, and the square profile may conveniently be a 60x40 profile with a thickness of 2 mm. The guide rails may conveniently be formed in polyamide. The construction ensures that the ladder steps are kept well and safely in the groove while the person moves on them, and since the choice of polyamide for guide rails at the same time has a low friction against the machine part, this provides a smooth running mechanism, where the braking force is determined by the brake wheel and not by variations in the frictional force between the machine part 28 and the rails 30.
    The square course of the conveyor device shown in FIG. 6 gives the advantage that the user has a clear and unambiguous picture of the steps of the ladder steps during use, as they are all moved either horizontally or vertically.
