Description

The present invention relates to a fitness apparatus wherein a user's body weight is used to generate a counterforce against a user's muscular strength, comprising: a base frame; a support member for supporting at least part of the body weight, the support member being hingedly connected to the base frame at a first end of the support member and having a bench for sitting and lying at a second end of the support member, the second end being formed as a free end is; and an operating part for introducing the muscular force into the fitness device, wherein the operating part is hinged to the base frame.

Fitness devices that use the body weight of the user to generate the counterforce, in contrast to conventional fitness equipment do not require heavy and thus accident-prone weights, which are otherwise to equip conventional fitness equipment to generate the counterforce. Such a fitness device is for example from the DE 199 28 505 A1 known. The fitness device disclosed therein comprises two flexible tension members in the form of chains or ropes for transmitting the movement of the operating member relative to the base frame on the support member. A disadvantage of the flexible tension elements is that they only transmit forces in one direction, namely the direction of pull, and require guidance. The necessary guide means complicate the construction of the fitness equipment significantly and limit its uses clearly.

The present invention is therefore based on the object to provide a fitness device of the type mentioned, which is simple and universally applicable.

To achieve this object, the invention proposes a fitness device of the type mentioned, which has a transmission rod, wherein the transmission rod is connected on the one hand to the support member and on the other hand with the actuating member and formed for transmitting a movement of the actuating member relative to the base frame on the support member. A transmission rod according to the present invention is inherently rigid or consists exclusively of rigid elements, which may optionally be hinged together. The transmission rod may be formed inside full or hollow. This means that the transmission rod can be designed as a rod or a pipe. The rigid transmission rod advantageously limits a number of degrees of freedom for transmitting the movement of the operating member relative to the base frame to the support member at three, two, or at best one. Thus, guide means are only required in small numbers or at best not at all, which simplifies the structure of the fitness device according to the invention. Due to a few deterministic paths on which the rigid transmission rod can only move, remains a relatively large space for adjusting the fitness equipment and oral by the user. Consequently, the fitness device according to the invention is universally applicable. In addition, it is generally known that exercising on fitness equipment is a monotonous process, which places high demands on the willpower of the user, especially in the case of highly stressful or long-lasting exercises. When using the fitness device according to the invention, each time the operating part is actuated, the user noticeably lifts his own body, which triggers a feeling of physical strength in the user which is conducive to a user's motivation. In this respect, the fitness device according to the invention promotes the motivation of the user.

According to an advantageous embodiment of the present invention, the fitness device has a translation device for adjusting the counterforce. For example, if the support member is loaded with the entire body weight of the user, the translating device is configured to set the counterforce to a value in a range of 10% to 300% of the body weight, in particular to a value of 50%, 100%, 150%. , 200% or 250% of body weight. A preferred translation device allows a modification of lever lengths of the support member and the actuating member.

According to a particularly advantageous embodiment of the present invention, the translation device comprises a threaded spindle and a positively driven nut on the threaded spindle, wherein the threaded spindle is rotatably mounted on the actuating part and wherein the nut is connected to the transmission rod. By means of this combination of threaded spindle and nut, the counterforce is stepless and adjustable. Depending on a pitch of a thread of the threaded spindle, the counterforce is very accurately adjustable. The lower the pitch of the thread, the more accurate the counterforce is adjustable. Furthermore, a small pitch allows a relatively small force to be set to adjust the counterforce. In a preferred variant, the thread is designed as a self-locking trapezoidal thread, so that locking means for locking the threaded spindle are obsolete. The threaded spindle has a length in a range of 50 cm to 150 cm, for example, a length of 70 cm, 90 cm, 110 cm or 130 cm. The threaded spindle has a diameter in a range of 2 cm to 8 cm, for example a diameter of 3 cm, 4 cm, 5 cm, 6 cm or 7 cm, preferably a diameter of 5 cm.

According to another embodiment of the present invention, the translation device comprises an electric motor for driving the threaded spindle. The electric motor allows an electrical adjustment of the counterforce, for example via a toggle switch or joystick, which is easy for the user to understand and easy to use. In addition, the electric motor allows automated adjustment of the counterforce without the user having to change the counterforce between two consecutive exercises. Thus, a stored in a control unit for controlling the electric motor training program can be performed. The training program may include uniform, interval-like, and / or pyramidal loads to induce the user in the best possible training stimulus. In the case of a threaded spindle with a low pitch, the electric motor can be dimensioned small and also a gear between the electric motor and the threaded spindle can be omitted. The electric motor is preferably a DC motor with an operating voltage in a range of 6 V to 48 V, in particular with an operating voltage of 12 V or 24 V, preferably with an operating voltage of 24 V. With great advantage, such a DC motor of a battery or a Accumulator be fed, so that fitness device according to the invention, despite the electric motor is highly mobile and suitable for use in changing locations. In a simpler embodiment of the fitness device or in the event of a failure of the electric motor, the threaded spindle can be manually driven by means of a lever.

According to a further particularly advantageous embodiment of the present invention, the transmission rod is displaceably connected on the one hand to the support member and on the other hand with the actuating member and the translation device comprises a first threaded spindle and a first nut positively guided on the first threaded spindle, wherein the first threaded spindle is rotatably mounted on the actuating member and wherein the first nut is connected to the transmission rod at a one-side end of the transmission rod, and the translating device comprises a second threaded spindle and a second nut forcibly guided on the second threaded spindle, wherein the second threaded spindle is rotatably mounted on the support member and wherein the second nut an other end of the transmission rod is connected to the transmission rod. In this embodiment, the transmission rod is positionable relative to the actuating part and to the support member, which gives the fitness device according to the invention a further degree of freedom to make it even more universally usable. The first threaded spindle and the second threaded spindle independently have a length in a range of 50 cm to 200 cm, for example, a length of 70 cm, 90 cm, 110 cm, 130 cm or 150 cm. The first threaded spindle and the second threaded spindle independently have a diameter in a range of 1 cm to 8 cm, for example a diameter of 2 cm, 3 cm, 4 cm, 5 cm, 6 cm or 7 cm, preferably a diameter of 3 cm.

According to a further embodiment of the present invention, provision is made here for the translation device to comprise rollers or carriages, wherein the rollers or carriages are fastened to the one-sided end and the other-side end of the transmission rod and are designed to be displaceable along the actuating part or along the carrier part. The rollers or carriages take over the power transmission between the actuating part and the transmission rod and between the support member and the transmission rod, wherein the rollers or slides are displaceable even under load along the actuating member or along the support member with only a small resistance. Furthermore, the rollers or carriages make the first threaded spindle and the second threaded spindle almost load-free.

According to an extremely advantageous embodiment of the present invention, the actuating part on both sides of an articulated connection point of the actuating part with the base frame on the base frame protruding, wherein the first threaded spindle is arranged on both sides of the connection point. This arrangement allows with great advantage pressure exercises and train exercises with the fitness device according to the invention. When the transmission rod is disposed with its one-sided end between the articulated connection point and the user, the fitness device is in an operating state for pressure exercises. When the transmission rod is disposed with its one-sided end relative to the user beyond the articulated connection point, the fitness device is in an operating state for train exercises.

According to a further embodiment of the present invention, it is provided that the transmission device comprises a first electric motor for driving the first threaded spindle and a second electric motor for driving the second threaded spindle. The advantages described above for the electric motor also apply here.

According to another embodiment of the present invention, the actuating part comprises a releasably secured to the actuating part Contact unit for contacting the fitness device by the user, wherein the contact unit is selected from a rod-shaped handle, a U-shaped handle and a running board. Depending on the exercise to be performed, the user must contact the exercise machine with either hands or feet. The contact units provided according to the invention are designed to be as gentle and fatigue-free as possible to the respective exercise, in order to make the contact, by means of which considerable muscular forces are transmitted. The contact unit optionally has additional handles.

According to a very advantageous embodiment of the present invention, the fitness device comprises a pulley, which is designed to act between the base frame and the actuating part. The pulley is arranged between the base frame and the actuating part, that the actuating part is indirectly actuated in a train on the pulley. For this purpose, the invention provides that on the base frame a lever is pivotally mounted, at its free end a roller is rotatably mounted, which rests with its running surface on the actuating part. A pivoting angle of the lever is a maximum of 85 °, to prevent blocking or turning over of the lever. In a pull on the pulley, an orientation of the lever changes relative to the base frame, so that the roller runs along the actuating part and thereby moves due to a fixed length of the lever, the actuating part relative to the base frame. A rope of the pulley is preferably designed as a highly tear-resistant static rope to avoid a rope elongation and to ensure a direct transmission of muscle power. By repeatedly pulling on the pulley a rowing can be simulated.

According to a further embodiment of the present invention, the transmission rod is adjustable in an existing between the support unit and the actuating unit effective length of the transmission rod. By adjusting the effective length of the transmission rod is a great advantage of a position of the actuating member relative to the position of the support member changeable. This is very advantageous because the user occupies different positions on the bench depending on the exercise to be performed and actuates the operating member with different limbs. For example, the user is sitting, kneeling or standing on the bench while operating the operating part with his or her hands or feet. The transmission rod is constructed, for example, telescopically.

Here, a rod or a tube of the transmission rod is arranged with an outer diameter in a further tube of the transmission rod with an inner diameter at least partially submerged, wherein the outer diameter is slightly smaller than the inner diameter to allow sliding of the rod or tube in the other tube , The length of the transmission rod is fixed by means of a spring-loaded bolt which engages in a hole of a plurality of holes, which is arranged along the transmission rod. Alternatively, the transmission rod may be formed as a rack or a threaded spindle or have a rack or a threaded spindle.

According to an alternative embodiment of the present invention, the effective length of the transmission rod is adjustable by means of a further electric motor. The advantages described above for the electric motor also apply here.

According to a particularly preferred embodiment of the present invention, the fitness device comprises a safety device for releasing and locking the fitness device, comprising: a rod having a plurality of holes, which is hingedly connected to the base frame, the holes covering at least part of a length of the rod are arranged distributed; a displaceable relative to the rod and forcibly guided by the rod sleeve which is connected to the actuating part; a spring biased by a spring disposed on the sleeve and formed for automatically engaging in the holes of the bolt; and a release linkage for disengaging the bolt from the holes and for holding the bolt in a disengaged state against the spring force. Upon actuation of the operating member by the user, the operating member is moved relative to the base frame. This means that their arrangement changes to each other. Since, on the one hand, the rod is rigid and articulated to the base frame and, on the other hand, the sleeve is connected to the actuating member, movement of the actuator relative to the base frame results in displacement of the sleeve along the rod, with displacement limited or complete by the bolt can be prevented by this engages in one of the holes of the rod and thus determines the sleeve on the rod. Since the bolt is spring-driven, it automatically engages with a displacement of the sleeve along the rod in the first hole, which hits the sleeve during the displacement. A distance between two adjacent holes of the rod is predetermined and chosen to be relatively small in order to provide a locking possibility in as many positions of the operating part. The distance is in a range of 2 cm to 8 cm, in particular 3 cm, 4 cm, 5 cm, 6 cm or 7 cm. Such small distances automatically prevent one unwanted large movement of the operating part, for example, if the user is no longer able due to advanced fatigue able to apply sufficient muscle power to compensate for the counterforce at least. The Ausrückgestänge is used in addition to the disengagement of the bolt from the holes also for holding the bolt in a disengaged state. Holding the bolt is very convenient because otherwise the user would need to hold the bolt permanently disengaged against the spring force while performing exercises. In this respect, the Ausrückgestänge improves the ease of use of the fitness device according to the invention considerably. The safety device for releasing and locking the fitness device therefore serves both to change the operating state and to prevent accidents and to improve the ease of use.

According to a further embodiment of the present invention, the security device comprises a status indicator, which is designed to display an operating state of the fitness device, wherein the operating state is selected from released and locked, and wherein the status indicator optical signal means or acoustic signaling means or optical and acoustic signaling means for displaying the Operating state has. The status indicator provides the user with safety-relevant information about the current operating state of the fitness device without the user having to have the safety device in view. This is very advantageous since, depending on the exercise to be performed, the user may occupy a position on the fitness device, from which he can not see the safety device and thus can not recognize the operating state of the fitness device. For example, the optical signal means are formed as a red LED panel and a green LED panel, which together constitute a traffic light-like arrangement. For example, the acoustic signal means are designed as a loudspeaker, which generates a sound or a sequence of tones in a transition from one operating state to another operating state, or which produces a continuous tone or a permanently repeating sound or a music stored in the fitness device in a specific operating state reproduces.

According to another further embodiment of the present invention, the release linkage is designed to disengage the bolt by means of manual or foot control or hand operation and foot operation by the user. As already described above, different exercises require that the user may occupy different positions on the fitness device. By inventively provided variability in terms of the manner of operation of Ausrückgestänges it is possible for the user in any imaginable position to operate the Ausrückgestänge adequately and thus to control the operating state of the fitness device.

According to yet another further development of the present invention, the Ausrückgestänge comprises at least three handles or steps for operating the Ausrückgestänges, wherein at least one handle or step above the support member and at least one handle or step is arranged below the support member. The thus distributed handles or steps allow operating the Ausrückgestänges and thus controlling the operating state of the fitness device in sitting, lying and standing positions of the user, which must be taken depending on the exercise to be performed by the user. In a preferred embodiment, the Ausrückgestänge comprises a handle and three steps, with a step above the support member and the handle and two steps are arranged below the support member.

According to a very advantageous further embodiment of the present invention, the fitness device is redundantly secured by means of the securing device and further securing means, which are selected from bolts and stops for limiting relative movements of parts of the fitness device to each other. Alternatively or in addition to the safety device described above, the fitness device may include further securing means to provide a redundant safety chain. Due to the considerable forces, namely the muscle power, the counterforce and the forces derived from these, the fitness device according to the invention is subject to a certain aging process, which can ultimately lead to a malfunction of the fitness equipment. In order for the malfunction, which can also affect the safety device, under no circumstances a risk of injury to the user, the fitness device has a redundant backup. This means that in the event of a malfunction, the fitness equipment can no longer be used and must be repaired, but at no time is there any danger to the life and limb of the user. The further securing means may be formed as: a bolt, which is also designed to automatically engage in the holes of the rod; a bolt which is designed to automatically engage in other abutments to possible Limit or completely prevent movements of the operating part, the supporting part or the transmission rod relative to the base frame; a stopper configured to limit possible movements of the operating member, the support member or the transmission rod relative to the base frame; or a stop pair, which is designed to limit or completely prevent possible movements of the operating part, the support member or the transmission rod relative to the base frame. The fitness device according to the invention preferably has one, two, three or four further securing means, each of which can be independently formed as a bolt with abutment, a stop or a pair of stops.

According to another embodiment of the present invention, the fitness apparatus is configured to perform at least the following exercises: bench press while lying, squeeze while sitting, shoulder slung while sitting, shoulder lift while standing, leg press while lying, calf raises while lying, calf raises while sitting, abdominal contraction while lying down , Sitting contraction of the muscular muscles, standing biceps contraction, lying triceps, sitting triceps, standing squats and rowing.
