Description

The invention relates to a device for performing a rowing exercise according to the preamble of claim 1. Such a device is made US2006 / 0264128 known.

Facilities for performing a rowing exercise, or also called rowing machines for short, are used for training of rowing on land, for example in winter or for targeted performance increase and are widely known. On the one hand, there are rudder devices which are intended for the training of competitive athletes and which are intended to enable a largely identical imitation of the kinematic conditions present in a real rowing boat and the load courses during real rowing, and which have complex movement and control devices for this purpose. The rudder loads caused by the interaction of the rudders with the water are in this case mimicked predominantly on the basis of elaborate resistance devices such as flywheels, fluidic drive elements, eddy current devices, etc., and can thus be easily influenced for optimum adaptation of the training conditions. An example of such a professional rowing machine is about in the US Pat. No. 8,235,874 B2 specified.

For the not so performance-oriented fitness area, there are a number of fitness equipment whose kinematics are partially aligned with the real rowing motion or at least mimic sections of the rudder movement. For example, from the DE 297 05 990 U1 a rowing machine is known in which the exerciser sits on a fixed seat and is supported with the breast against a counter-holder. The arms perform a rudder-like movement via a kind of lever system, wherein the weight stack frequently used in the fitness area for reasons of simple construction and the associated robustness are used as the resistance element, which are connected to the lever system via cable pull devices and deflection rollers. Such fitness devices have the disadvantage that the movement to be performed is only very remotely similar to the real rowing movement due to the largely predetermined posture of the exerciser and the design of the lever system. On the other hand, the use of the weight stack as a resistance element is problematic in that with faster or with higher clock running oar-like movements of the weight stack due to its inertia and the lack of direct coupling with the lever system can perform uncontrollable or aufzuschkelnde movements. If the exerciser executes rudder-like movements with a high frequency, the weight stack moves slightly, since the cables which are normally used only transmit the movement of the lever system to the weight stack by train, but the inverse movement of the weight stack is thus delayed and possibly delayed or unsynchronized to the movement of the lever system takes place. At the end of the lifting movement, the weight may overshoot slightly beyond the upper reversal point due to its inertia and unguided movement, thereby disturbing the synchronization of the rudder movement and lifting movement. After reaching the thus extended top dead center then the weight falls unguided back down and generates unwanted force peaks on the rudder bars. This can lead to the fact that the weight stack can virtually lead to a kind of own life, which no longer correlates with the movement of the lever system and makes it difficult or impossible to carry out a reproducible oar-like movement.

Object of the present invention is therefore to propose a means for performing a rowing exercise, with the also for the fitness area and Inexpensive, a close approximation to the real rowing motion and its controlled implementation in each state of motion is possible.

The solution of the object of the invention results from the characterizing features of claim 1 in conjunction with the features of the preamble. Further advantageous embodiments of the invention will become apparent from the dependent claims.

The invention relates to a device for performing a rowing exercise, comprising an arrangement of a on the base frame relative to the rotatable mounting of the rudder bars slidably disposed seat for a rowing and two rotatably mounted and independently movable rudder bars of the rowing in the implementation the rudder movement must be moved around a resistance around their pivot bearing around. Such a device is further developed by the fact that the seat is slidably mounted on the base frame relative to the rotatable mounting of the rudder bars and the rudder bars are connected by means of a continuously extending between the rudder rods traction means with a resistance means of an arrangement of raisable and lowerable weights, wherein the traction means is guided so that the lifting movement of the weights in the implementation of the rudder movement is slower and / or smaller than the displacement of the traction means in the region of the rudder bars. On the one hand, the displaceable arrangement of the seat for the rowers also ensures that the rower's not so performance-oriented field of application in gyms or the like ensures that the rowing and leg movement of the rowers largely corresponds to those of the real rowing. Here, the legs are supported on a footprint during the rowing motion and the pulling part of the rowing motion of the rowing moves forward with the seat, thereby bending the knees, whereas he stretches the legs when repelling the rudder bars again and the seat based on the footprint again pushes backwards. This is much more harmonic and less stressful than the largely stationary posture of the body in known devices of rudder-like devices in gyms. The resistance device of an arrangement of raisable and lowerable weights further avoids the uncontrolled swinging and unsynchronized Own life of the weights relative to the movement of the rudder bars in that the lifting movement of the weights in the implementation of the rudder movement is slower and / or less than the displacement of the traction means in the region of the rudder bars. By this translation of the movement of the rudder bars in the slow or in a smaller stroke in conventional so-called. Rudergeräten easily occurring problems are minimized or completely avoided by the movement of the weight of the resistance device is carried out slower and with less amplitude, resulting in an overall dynamic this movement of the weight dampens and thus ensures a largely synchronous movement of the rudder bars by the rowing and the movement of the weight of the resistance device. Thus, even with dynamic and powerful rowing a very reliable and thus pleasant for the rowing movement behavior of the weight can be achieved. This further avoids having to use maintenance-prone or expensive resistance devices for the field of application of the rowing machine in fitness studios which, for example, function fluidly or electrically and which can easily be overstressed due to the frequent use in fitness studios. Thus, the rudder device according to the invention offers in many areas of the actual rowing corresponding or approaching training option, which can nevertheless be implemented with simple means and therefore is inexpensive and robust and thus suitable for gyms.

It is particularly advantageous if the rudder bars are rotatably mounted at laterally and transversely to the direction of displacement of the seat of the base frame bracket-like protruding supports and continue to largely correspond to the lengths and the arrangement of the rotatable mounting of the rudder rods the kinematic conditions of the real rowing boat. This can be achieved that the rowing perceives little or no difference to the real rowing movement and therefore he has no habituation effects, if he trained in a real rowing boat. In addition, the very close to the real rowing movement rowing movement of the device according to the invention is designed very body friendly and charged the body of the rowing not with inharmonious movements, which otherwise often have to be performed in conventional rudder-like facilities for the gym. Thus, the invention is suitable Rowing machine especially for inexperienced exercisers or exercisers with physical limitations.

In a further embodiment, the axes of storage of the rudder bars can be arranged inclined to the vertical, to allow an anatomically favorable and the kinematic conditions of the real rowing boat largely corresponding movement of the rudder bars. This inclined arrangement of the bearing of the rudder bars leads to a further approximation of the movement of the rudder bars of the device according to the invention to the movements of the real rowing boat, in addition, the rudder bars can perform an overlapping movement of the handle ends of the rudder rods as usual in the real rowing boat.

It is particularly advantageous if the resistance device is arranged centrally in extension of the sliding movement of the seat in front of the rowing on the base frame. As a result, the leadership of the traction means is particularly simple designable and the arrangement of the resistance device leads to a symmetrical structure of the rudder device.

In a further embodiment, it is conceivable that the traction means have bands or chains or the like., Which are articulated to the rudder bars. Bands or chains are particularly easy to influence because of their compliance and easy deflectability and thus allow a little power-consuming deflection of the force of the rudder movement on the weights of the resistance device. It is advantageous in this case in particular that the traction means can be deflected by the rudder bars via pulleys to the resistance device. Such pulleys can be easily arranged on a base frame of the rudder and allow a spatially more complex management of traction means, which can be safely prevented by appropriate design of the pulleys with guides for the traction means jumping off the traction means of the pulleys. As a result, in particular for the rough operation of the rudder device for the fitness area with partially inexperienced users additional security during operation and avoidance of defects or damage is achieved.

It is particularly advantageous if a continuous band or the like is provided as the traction means, which runs from a rudder rod over the deflection rollers and the resistance device to the other rudder rod. This continuous traction means, together with the pulleys and the articulation of the resistance device allows a largely optimal movement characteristics of the weights of the resistance device depending on the movement of the rudder bars. It does not matter whether the rowing only one rudder bar or both rudder bars unevenly or both rudder bars pressed evenly, since the movement of each rudder bar is transmitted due to the continuous traction means always safe and independent of the movement of the other rudder bar to the weight of the resistance device.

Furthermore, it is for the operation of the rudder device advantageous if the seat via a sliding bearing or a roller bearing, preferably roller bearings on guide rods, relative to the base frame is arranged to be easily movable. This allows the rower with little effort perform the associated leg movements while performing the rowing, similar to the case in a real rowing boat.

An increase in the load of the rowing with respect to the leg movements can be achieved if the seat is arranged so that it can move easily on the base frame, that the displacement axis of the seat is adjustable horizontally inclined to the base frame. In particular, when the displacement axis of the seat is arranged relative to the base frame so that the seat is located higher in its from the axis of rotation of the rudder rods farthest end position than in its closer to the axis of rotation of the rudder rods end position, the rowers must overcome this additional height difference when he moves due to the leg movements the seat along the longitudinal axis of the rudder device. This leads to additional training effects especially for the legs of the rowers. For the practical implementation of this additional burden, it is possible, for example, that the base frame is designed to be height-adjustable at one end, wherein the end-side height adjustment of the base frame pivots the displacement axis of the seat. Of course, but only the movement of the Seat separately from the base frame have this advantageous inclination or occupy.

A further or alternative increase in the load of the rowing with respect to the leg movements can be achieved that between the seat and base frame a loading device is arranged such that the to be performed by the rowing relative movement between the seat and base frame is executable only against an additional resistance. As a result, a further targeted increase in the load of the leg movements of the rowing can be achieved, whereby additional training effects of these body parts can be achieved and the training can be characterized additionally effective and uniform in terms of the burden of upper body and lower body. In this case, the loading device may preferably have an arrangement of elastically extensible bands or the like and / or mechanical spring elements and / or pneumatic cylinder and / or hydraulic cylinder, through which the additional resistance in the relative movement between the seat and base frame, preferably adjustable, is caused. Thus, e.g. a respective elastically stretchable band on the left and right of sliding seat so arranged and biased between the frame and seat, that during the backward movement of the seat in the rowing movement, these bands must be stretched and thus by the rowing an increased force must be applied to the Move the seat backward during the rudder movement. Instead of such bands and mechanical spring elements and / or pneumatic and / or hydraulic cylinders between the frame and seat can be arranged so that in the backward movement of the seat during the rowing movement must be worked against this respective spring force and thereby the above-mentioned additional training effect is achieved.

In a further embodiment, it is conceivable that along the displacement axis of the seat displaceably adjustable footrest is arranged fixed to the base frame on which the rowing rests in the implementation of the rudder movement. Such a footrest, which in particular can also be arranged angle-adjustable on the base frame, thus offering the opportunity to be adjusted appropriately for each rowing can. This allows the rowers before the rowing the rudder device to his very individual circumstances in terms of leg lengths, most comfortable inclination of the foot support, etc., whereby the training process can be improved overall and less burdening the body can be performed.

In a first conceivable embodiment, the resistance device may have at least three deflection rollers, wherein two of the deflection rollers are fixed symmetrically to the lifting axis of the weights on the liftable support means of the weights and the third deflection roller centrally above the two deflection rollers fixed, preferably stationary rotatable on the frame of the device, is arranged. The pulleys on the liftable support means of the weights act quasi as loose roles. Through this guidance of the traction means in the region of the resistance device, it is ensured that the pulling movement transmitted by the rudder rods to the traction means is transmitted with reduced stroke to the weight of the resistance device. A transmitted from the rudder bars on the traction means pulling movement only leads to half the lifting movement of the weight, whereby dynamic effects such as the lifting speed or the acceleration of the weight are reduced accordingly at the upper and lower deflection points. Thus, even at a high speed of movement of the rudder bars, it can be ensured that the movement of the weight of the resistance device fails immediately in synchronism with the rudder movement and that there is no overshoot or other uncontrollable movement of the weight of the resistance device. It is also conceivable to arrange more than two loose rollers on the support means of the weights so that a stronger translation of the movement of the rudder bars is achieved on the movement of the support means.

It is particularly advantageous if the arrangement of the deflection rollers is formed symmetrically to the displacement axis of the seat. As a result, the deflection of the traction means is achieved with a simple construction that has the same characteristics for the right rudder rod as for the left rudder rod.

In a further embodiment, the traction means of the one rudder rod via a disposed adjacent to the pivot point of this rudder rod lower pulley up to a second deflection roller arranged above, from there to a, closer to the resistance means arranged third deflection roller and from this third deflection roller run down to one of the two pulleys on the liftable support means of the weights. By such an arrangement, it is possible to remove the movement of the traction means relatively close to the articulation point of the rudder bars of the respective rudder rod and to transmit over the arrangement of the pulleys on the pulleys on the weights without too long lengths of the traction means are required. At the same time, it can be ensured, for example, by the deflection rollers arranged adjacent to the fulcrum points of the rudder bars, if these deflection rollers are pivotable about a vertical axis, so that these deflection rollers always align themselves with the position and the circular movement of the articulation point of the traction means on the rudder rod. Thus, optimal transmission ratios of the movement of the rudder bars to the traction means and the pulleys secure transmission to the weights of the resistance device allows.

It is conceivable in a further embodiment that the adjacent to the pivot points of the rudder bars arranged pulleys are rotatably mounted on lateral arms of the base frame. As a result, these pulleys can be arranged with little construction effort within the rudder device, that the traction means is always relatively close to its articulation to the respective rudder rod with the first guide roller corresponding in Verbding.

It is also conceivable that the overhead arranged deflection rollers are arranged rotatably on V-shaped aligned with each other arms of the base frame. The overhead deflection rollers can thereby be arranged above the adjacent to the pivot points of the rudder bars deflection rollers, preferably directly above these pulleys.

Furthermore, it is advantageous if the carrier device of the weights has a guide device, preferably one or more rods, which guides the lifting and lowering movement of the weights. As a result, an unintended inherent life of the weights of the resistance device due to dynamic effects due to the rudder movement is further reduced.

For constructive implementation of the weights of the resistance device, it is conceivable that as weights on the liftable support means for the weights Slices can be attached. This is according to the weight weights for the fitness area widely used and the users of the rowing equipment in the gym immediately familiar. However, it is of course also conceivable that as weights on the liftable support means for the weights plates are provided which can be coupled by means of plug-in elements individually or in stacks with the support means. Again, this is familiar to users of the rowing equipment directly from other fitness equipment

A particularly preferred embodiment of the rudder device according to the invention is shown in the drawing.

FIG. 2

- A view of the rudder device according to the invention approximately from the perspective of the rowing in the direction of the resistance device with representation of the course of the traction device via pulleys.

In the FIG. 1 is a schematic plan view of the inventive rowing device 1 with the sliding seat 3 and the course of the traction means 6 between the rudder bars 4 and the weights 7 of the resistance device 8 shown and explained. The rowing device 1 is based on an example rectangular base frame 2 made of steel profiles, which rests with a front support 18 and a rear support 16 on the ground. Laterally, the base frame 2 and the supports 16, 18 stabilized by Fußstangen 17 which protrude laterally from the supports 16, 18 and laterally transmit forces to the ground.

Within the base frame 2, the longitudinally displaceable along the direction of displacement 21 seat 3 via two parallel guide rods 15 is slidably supported on the base frame 2, wherein the seat 3 not shown guide elements such as ball slides smoothly slide on the guide rods 15. hereby Only little power of the rowing is needed for this adjustment of the seat 3.

On the side of the base frame 2 are each a console-like projecting support 14 obliquely downwards and forwards arranged at its freely projecting from the base frame 2 end only schematically indicated pivot bearing 5 for each rowing rod 4 is indicated, in which the rudder bar 4 rotatably mounted Rotary movement along the direction of rotation 23 can perform as a real rowing boat. The rudder bars 4 are designed so long and protrude from the pivot bearing 5 away so in the interior of the base frame 2 that the rowing, sitting on the seat 3, the rudder bars 4 can operate in front of his chest almost like a real rowing boat.

Thus, the rowers sitting on the seat 3 and show his legs in the direction of the front support 18, can be supported on the rudder device 1 with the legs, in the direction of displacement 21 in front of the range of movement of the seat 3 along the direction of displacement 21 adjustable and customizable diagonally flip-up footrest 19 is provided, on which the rowers as in rowing in a rowboat supported his feet when performing the rudder movement and so can move the seat 3 along the direction of displacement 21 by stretching and tightening the legs.

Arranged at the front end of the base frame 2 on the support 18 is a resistance device 8, which is described below, which ensures that the rowing person experiences a resistance during the actuation of the rudder bars 4, which largely corresponds to the resistance of the oars of a real rowing boat gliding through the water , This purpose is served by a stack of, for example, plate-shaped or disc-shaped weights 7, which can perform a lifting movement in the lifting direction 24 in a guide frame 11. Due to gravity, a lifting force is required to lift these weights 7 against gravity, which applies the rowing by tightening the rudder bars 4 towards his body. This corresponds to the resistance of the water, which the rower must muster in real rowing while pulling the rudder against the water. During the return movement of the rudder rod 4 back to the front of this weight stack 7 is lowered again under the influence of gravity, with this return movement of the weight stack 7 takes place in the lowering 24 without much effort for the rowers.

To lift the weight stack 7, the rudder bars 4 are connected by means of a pulling means 6 extending continuously between the rudder bars 4, such as a band or a chain or the like. This traction means 6 is articulated in the area of the rudder bars 4 and extends over different deflection rollers 9, 9 'into the region of the resistance device 8 and actuates there the stack of the weights 7.

Approximately at the height of the rudder bars 4 are seen left and right from the rowing from two lower front pulleys 9 at a lower cross member 13 ends, the two lower front guide rollers 9 about an approximately vertical axis in Anstellrichtung 22 rotatably on the lower crossbar 13th are attached. Due to the rotational movement of the articulation point of the traction means 6 on the rudder bars 4, the lower front guide rollers 9 can adapt to the circular movement of this articulation point of the traction means 6 to the rudder bars 4 to 6 safely lead the traction means can.

Of the lower front guide rollers 9, the traction means 6 extends on both sides approximately vertically upwards to an outer upper guide roller 9 ', which is fastened on the end side to an upper cross member 10, which in turn protrudes laterally on both sides of a further front support 12 is approximately V-shaped, that the free ends of the upper cross member 10 are located approximately above the lower front guide rollers 9. As a result, the traction means 6 can be guided approximately vertically upwards from the lower front deflection roller 9 to the outer upper deflection roller 9 'and from there horizontally guided to an inner upper deflection roller 9' fastened to the same upper traverse 10. This inner upper deflection roller 9 ', in turn, is located close to the support 18, approximately above the guide frame 11 for the stack of weights 7.

The stack of weights 7 now has on both sides in each case a lower loose deflection roller 9 ", which are rotatably mounted on a carrier plate 25 for the stack of weights 7. The traction means 6 coming from above from the inner upper deflection roller 9 'is moved over the respective Lower loose pulley 9 "and back up to an upper middle deflection roller 9 '', which is fixed but rotatably attached to the support 18. The two lower loose deflection rollers 9 "and the upper middle deflection roller 9 '" ensure the lifting movement of the stack of weights 7, when the Pulling means 6 is pulled by unilateral or bilateral actuation of the rudder bars 4. In this case takes place due to the guidance of the traction means 6 on the pulleys 9 "and 9 '" the lifting movement of the stack of weights 7 at half the speed of movement of the traction means 6 due to the rotational movement of 4. This ensures that even with rapid movements of the rudder bars 4, for example, in a powerful rowing the stroke of the stack of weights 7 substantially shorter and therefore, for example, an uncontrolled rocking of the lifting movement of the stack of weights 7 due to the rudder dynamics can not be done ,

Another burden of the rowing to improve the training can be applied, that the sliding movement of the seat 3 relative to the horizontal can be tilted. Thus, e.g. be ensured by an adjustment of the rear end of the base frame 2 in the adjustment 20 via a height adjustment of the support 16 that the rowing the seat 3 must move to the rear and a little way up, creating an additional training effect for the legs of the rowing.

A further or alternative increase in the load of the rowing with respect to the leg movements can be achieved that between seat 3 and 2 base frame in the FIG. 1 only schematically indicated loading device 26 is arranged such that the to be carried out by the rowing relative movement between the seat 3 and the base frame 2 can be executed only against an additional resistance. For this purpose, the loading device as in the FIG. 1 indicated an arrangement of elastically stretchable bands or the like. Or alternatively or additionally also of mechanical spring elements or pneumatic or hydraulic cylinders, through which the additional resistance in the relative movement between the seat and the base frame is caused. So can like in the FIG. 1 indicated as an elastically stretchable band 26 each left and right of the sliding seat 3 are arranged and biased between frame 2 and seat 3, that in the backward movement 21 of the seat 3 in the rowing motion 23 these bands must be stretched 26 and thereby an increased force must be applied by the rowing to move the seat 3 in the rowing movement 23 to the rear.
