Abstract

The invention relates to an exercise device comprising a foot plate that is mounted to carry out a wobbling movement. According to the invention, the foot plate is connected to a supporting device that is designed to surround the pelvic area of a user's body, the user's body being supported in the supporting device in all transversal directions transversally to the surface normal of the contact surface on the foot plate. The upper body of the user can therefore be inclined in all directions in relation to the substantially fixed pelvic area, thus allowing a plurality of muscles to be effectively exercised using a simple sequence of movements.

Description

exerciser

The invention relates to a training device with a tread.

Among the large number of different training devices are also devices in which a tread plate has an upwardly facing tread surface and is mounted to perform a tumbling motion.

In a known from CH 448838 exercise device, a tread plate is supported by a stub axle on the ground and can roll with an edge curve on the floor performing a tumbling movement by the standing with both legs on the tread of the treadle user shifts its center of gravity. The user can grip with the hands of a centrally attached to the top of the treadle strap.

A known from DE 1917740 U1 gymnastic device also has a swash plate, which is supported centrally against a pad. The height of the support can be varied by means of washers, whereby the inclination of the tread surface is invariably adjustable against the vertical. A comparable device is described in DE 1426843 A1.

In DE 93 14 308 U1 a device for training of body parts is disclosed, in which an inclined seat over a bearing element rotatably mounted on a support member and by body movements of the user or can be driven by a motor. Instead of the seat, a lying surface, a head, foot or hand recording can be provided.

DE 19648346 C1 shows a training device with a larger tread on which a user can move and which of a is surrounded, which the user can grip with his hands to evaluate by shifting the center of gravity wobbling of the centrally mounted device. Likewise, a large bearing surface has a sports device described in WO 95/31256 A1, on which the user assumes a more lying position. A shift of emphasis is possible by means of a footrest movable on rollers on the support surface.

Swash plates are also known for play equipment. Thus, for example, DE 10040145 C2 shows a game machine in which a base plate provides a tread for two or more people, which grip a centrally from the tread surface upstanding handle assembly with hands. DE 7929240 U1 describes a disk swing, the tread surface is surrounded by a railing and provides space for several children who can hold on brackets.

It turns out that the known training devices with swashplates do not produce a satisfactory training effect and often even cause the user to unfavorable body postures.

The invention has for its object to provide a simple design and intuitive easy to understand training device with a high training effect.

The invention is described in the independent claim. The dependent claims contain advantageous refinements and developments of the invention.

Due to the transverse support of the pelvis of a user standing on the tread, the pelvic area of the user's body is largely in the advises fixed and for generating the wobbling movement by means of weight shift and / or to compensate for the forces acting variable on the body during the wobbling movement of the treadle forces a variety of muscles, in particular the trunk muscles claimed and trained without an overuse occurs. In particular, in the preferred embodiment, in which occurs without motor drive, the tumbling motion of the treadle solely by shifting the focus of the user, the training intensity is advantageously completely influenced by the user and the training effect is particularly high.

The training effect of the exercise device according to the invention with the transverse support of the pelvic region of a user body is clearly different from the training effect in devices with lying or sitting position of the user or with handles to which a user holds.

Advantageously, the user has a secure hold in the device both arms and hands free and can, for. B. by means of dumbbells further muscle specifically trained in addition. In particular, dumbbells can also be advantageously used for shifting the center of gravity. In the typical use of the device with a periodic movement, the support and the user's pelvic region substantially fixed by the device with respect to the device, move annularly about a vertical axis of rotation of the tumbling motion. The movement is in the simplest case substantially circular, can also deliberately differ from the circular shape by design of the storage or in particular the rolling track to z. For example, consider different mobilities of the human body in different directions. In the following, for the sake of simplicity, without limiting the generality, a circular movement of the holder about a vertical axis of rotation is assumed. The rolling track is then assumed to be circular. Various types of storage of a tumbling plate are known per se in the prior art.

The holding device is formed in a preferred embodiment for a circumferential enclosure of standing on the tread user body in the pelvic region, with low position deviations on the user body up or down are generally not critical. Without restricting generality, the holding device is subsequently divided into a part which is referred to as a holding ring and forms the pelvic area, and a part which is connected substantially rigidly to the tread plate and is spaced from the tread plate and carries the holding ring, generally referred to as a strut Strive to have any, even multi-part shape and can also be connected at several points with the treadle. The retaining ring of the holding device is advantageously held vertically adjustable on the strut and thereby adaptable in height to different body sizes.

In an advantageous embodiment, the retaining ring of the holding device contains a rigid half-shell and / or a preferably length-adjustable belt. The

Width of the half-shell can advantageously be variable adjustable. To adapt to different body shapes additional, replaceable fitting elements can be provided detachably in the back and side region of the half-shell. In the front region of the retaining ring, a pressure compensation liner can be provided for the areal distribution of centrifugal forces.

The retaining ring may advantageously be held tiltably on the strut and so facilitate the relative movements of the body, which occur in the typical use of the device. In a development, the retaining ring can be connected to a ner limited transverse mobility against restoring, centering spring forces in a relative to the strut and the tread plate rigid ring segment or the like to be held. The retaining ring may be partially padded and / or circumferentially on the user body side facing advantageously upholstered.

The device can contain a sensor device in an advantageous development, which detects at least one movement parameter when using the device. Movement characteristics may, for example, be rotational speeds of the tumbling motion about a vertical center axis, total number of revolutions about said vertical axis in both opposite directions of rotation, centrifugal forces occurring, inclination of the tread surface, accelerations of the rotation of the tumbling motion and the like. Advantageously, a display device for displaying one or more such motion characteristics or one or more derived therefrom in a preferably electronic evaluation device parameters may be provided, wherein in the evaluation device also measured values on the user body, such as heart rate, respiratory rate or the like can be considered.

The tread surface advantageously has a diameter of less than 80 cm, in particular less than 60 cm, so that the size of the tread plate can advantageously be kept low for a person sufficiently large tread.

The rolling path surrounding the central region or a vertical axis about which the tread plate rotates during the tumbling movement can advantageously have a smaller diameter than the tread plate and under the tread surface against its outer circumference in the direction of the central region be arranged offset radially inward, so that the risk of trapping objects or body parts is reduced in the region of the rolling track. The outer periphery of the tread plate may be surrounded by a cuff of soft material and / or connected by a flexible bellows, such as a bellows with the pad to reduce any risk of injury to people standing next to the device.

Since, in the use of the device by the holding device a large radial distance of the weight center of gravity is forced by the vertical axis of rotation of the tumbling motion compared to known swash plate devices, occur at low rotational speeds considerable centrifugal forces on the holding device, which cause tilting moments on the treadle. For this purpose, the tread plate is advantageously secured in its central region against a lifting off the base beyond the selected inclination of the tread surface. In a first embodiment, the optionally variable distance of the tread from the base is fixed and held the tread plate in the vertical direction up and down in the selected position, so that the tread always occupies the selected inclination to the vertical, said inclination in the general case as mentioned may vary depending on the angular position of the tread about the vertical axis of rotation of the tumbling motion. In another advantageous embodiment can be provided that the tread plate occupies a central position, in particular with a substantially flat tread surface in a rest position, in which the vertical distance of the central region of the tread plate to the base is smaller than in the operating position with inclined tread. The user can then enter the tread surface in an upright position and close the holding device and then further tilt the central area of the tread plate from the base by tilting it sideways and establish the operating position of the appliance. If necessary adjustable stop for the lifting movement of the central area can be limited.

Depending on the type of mounting, the tumbling motion of the tread plate can be coupled to a rotation of the tread plate about a center axis of the tread plate, so that the user's horizontal viewing direction slowly rotates about the axis of rotation of the tumbling motion with multiple rotations of the tumbling motion. The rotational speed of such a rotation is typically substantially less than the rotational speed of the tumbling motion. If such superimposed rotation is to be omitted entirely, this can be done by suitable means, in particular in the bearing arrangement, via which the tread plate is connected to the base, which block such self-rotation of the tread plate. In particular, the storage can take place via a universal joint, which is connected in a rotationally fixed manner with its two connecting shaft sections to the base or the tread plate. In another embodiment, a running between tread plate and pad axle body can be positively secured against rotation.

The base on which the tread plate is supported in its and on the rolling track and held in the central region can be formed by a bottom surface. Preferably, a support holding the tread plate in the central region and supporting it in the region of the rolling track is an integral part of the device as a base plate and / or as a base. Such an integrated pad can for high stability of the device on a substrate, eg. B. a Bodenflä- anchored surface or by a sufficient diameter, which can be secured against tipping over by several individual struts, which may be telescopically or pivotally. The holding device designed to surround the pelvic region of a person standing on the tread can be detachable from the tread plate and / or interchangeable with another device, also known per se in connection with swash plates, so that the tread plate itself, in addition to the new type of training enabled by the invention can also be used in a known manner.

The inclination of the tread plate against the pad can be advantageously adjustable.

1 shows a first advantageous embodiment of a training device according to the invention, in which a tread plate TP is held on a base plate GP via a joint TG. The tread plate TP and the base plate GP are assumed to be flat plates for the sake of simplicity, without this being mandatory. The surface normal of the tread plate TP is inclined against the surface normal of the base plate GP. The tread plate TP is mounted in the joint TG in a conventional manner so that the tread TP unrolls along its running track LB on the base plate GP while performing a tumbling movement with its outer edge. Various joint arrangements and variations of the support of the tread plate with respect to a pad to allow a wobbling movement of the tread plate are per se from the aforementioned The prior art is known and are included without limitation in the illustrated embodiment below as modifications.

A strut ST, which projects upwards from the tread surface TF of the tread plate TP, is rigidly connected to the tread plate. On the strut ST upwardly spaced from the tread plate TP a half-shell HS is attached via a headband HB, which is closed by a belt GU on the side facing away from the headband HB to a retaining ring HR. A user turns to use the device on the tread plate TP and leans with the belt GU open with the body back in the pelvic area in the half shell HS. By closing the belt GU in front of the front side of the user's body, half shell HS and GU form a pelvic area of the user completely and preferably free of play or with little play comprising retaining ring HR. To adapt to different body dimensions, the width of the retaining ring by means of the belt GU is adjustable and / or the height of the retaining ring HR on the tread TF is adjustable by moving the retaining clip HB along the strut ST to different body sizes. The unit consisting of tread plate TP, strut ST, headband HB and retaining ring HR formed by half shell HS and strap GU is also referred to below as the moving part of the device and thus distinguished from the stationary base plate or another stationary base.

The user held in the described manner in the moving part in the pelvic area and standing with his feet on the tread surface TF user can shift in particular by movement of the upper body relative to the pelvic area, the overall center of gravity of user body and moving part and so set a wobbling motion of the treadle in motion. The required for the continued wobbling permanent displacement of the center of gravity a variety of muscles of the body are claimed, wherein also by the varying weight distribution, the leg muscles are subject to change and trained. The user advantageously has the arms free and can contribute with these in addition to the center of gravity, in particular, given the possibility that the user performs by hand-held dumbbells and their varying orientation intensive training of the arm, shoulder and chest muscles. The user can largely determine and vary the training intensity himself.

During the tumbling motion, centrifugal forces (centrifugal forces) occur already at a low rotational frequency of a few revolutions per minute of the tread plate TP along the track LB on the base plate GP, which cause a tipping moment on the tread plate TP about its edge support on the track LB in the sense in that these tilting moments are directed at the tread plate TP in the center ZP of the base plate GP. The tread plate TP is therefore held in its center ZP against lifting from the base GP. For example, for this purpose, the joint TG can be fixed both with the base plate GP and with the tread plate TP against lifting relative movements in the direction of the respective surface normal.

The half-shell is illustrated in FIG. 1 as comprising the body approximately 180 °. The extent of the enclosure by the half-shell is variable. Also, the half shell HS is not considered to be rigid in the sense of completely undeformable. The half-shell can also be elastically deformable and expandable or contractible under the action of the tension on the belt GU. It is essential that the body is supported in all directions transversely to the surface normal NT of the tread plate TP. In this case, the surface normal is defined as the surface normal to the curve that rolls off the track LB on the track LB, which in the case of a flat pedal plate is equal to the surface normal of the plate surface or the tread is. For non-flat tread plate or tread surface, the above definition of the surface normal is meant.

Fig. 2 shows a moving part in side view, in which the moving part is aligned with in the drawing upright surface normal NT of the tread TF of the tread plate TP. FIG. 3 shows a representation of the moving part according to FIG. 2 with a view from the strut ST located on the rear side of the user's body, and FIG. 4 shows a view from above with a viewing direction in the direction of the surface normal NT. In the center of the tread plate TP designated ZP, the plate is held in the operating position shown in FIG. 1 relative to the stationary base.

For the further description, a fictitious center plane MH in the direction of the surface normal NT at the level of the belt GU is assumed for the retaining ring formed by half shell HS and belt GU. The area surrounded by the retaining ring in this fictitious plane MH has a centroid whose position is indicated by the broken line ZH and which is offset from the surface normal NT via the center ZP of the tread plate TP to the strut ST, ie in the direction of the rear side of the user body , As a result, the different mobility of the body for forward and backward forward bends are advantageously taken into account. The headband HB is about a fastener, such as a locking screw SS at different heights on the tread TF, in predetermined levels or preferably continuously, variably fixed, so that the height of the retaining ring over the tread plate is adjustable and adaptable to different body sizes. The strut ST is advantageously aligned inclined at least in the adjustment of the retaining bracket against the surface normal NT in such a way that increases with increasing height above the tread surface TF, the distance of the strut ST of the surface normal NT. The moving part is advantageously constructed mirror-symmetrically with respect to a symmetry plane SE containing the surface normal through the center ZP of the tread plate.

In the plan view of the arrangement according to FIG. 4, the retaining ring formed by half shell HS and belt GU is represented schematically by an oval line in the region of the center plane MH. From the illustration according to FIG. 4, the offset of the area center of gravity of the area surrounded by the retaining ring HR relative to the surface normal NT through the center ZP of the tread plate TP towards the rear, that is d. H. in the direction of the half-shell or the retaining clip.

In Fig. 5, a training device in the operating position is shown in side view. The as just assumed tread plate TP includes with the also just assumed base plate GP an angle KW. This angle also occurs between the surface normal of the base plate GP passing through the joint KG and the surface normal NT of the tread plate TP. The surface normal NT of the tread plate TP runs in the tumbling motion of the moving part on the coat of an upwardly widening cone whose tip lies in the joint KG. Such a revolution of the surface normal NT is indicated by the curve TK in FIG. The construction of the device can preferably take place in such a way that the viewing direction of the user relative to the stationary base plate GP does not change during the tumbling movement of the moving part. With a broken line, a position of the retaining ring is shown in FIG. 5, in which the moving part has carried out a 180 ° further movement of the tumbling motion relative to the position indicated by the solid line. Maintaining the viewing direction of the user can be achieved, in particular, by designing the joint KG as a universal joint. sen both articulated arms each rotatably connected to the base GP or the tread plate TP are connected.

In FIG. 5, the strut is shown as a telescopic strut with a telescopic inner part T1 fastened to the step plate TP and with a telescopic outer part TA carrying the retaining clip HB, the two telescopic parts being displaceable relative to one another and in different directions in the direction of their common longitudinal axis Longitudinal positions are fixed to each other, for which again a locking screw SS is shown as an example.

6 shows an advantageous embodiment of the connection of the half shell HS with the strut ST via a joint inserted in the retaining clip HB, for example an elastomer joint GL, which to a limited extent tilting of the retaining ring about a tilt axis RA extending transversely to said symmetry plane SE and / or or allows a further tilting axis NA transversely to the surface normal NT in the plane of symmetry SE, which favors the movement of the user held in the pelvic area in the retaining ring during the training phase.

Fig. 7 shows an embodiment in which the moving part can take a drawn with a solid line rest position in which the tread plate TP is parallel to the base plate GP. The moving part can be brought from this rest position by lateral tilting in any direction in the drawn with a broken line operating position in which the tread plate is inclined at an angle to the base plate. The tread plate has a central recess PA, by means of which the base plate slides during tilting along a support pin ZB connected to the base plate GP and abuts the extended head BK of the bolt ZB and against further Lifting off the base plate is secured. The underside of the bolt head BK can be designed rounded this favorably.

Fig. 8 shows a variation of the transverse support of the pelvic region of a user body embracing retaining ring HF, which is connected to several sides via springs FE elastic with fixed relative to the tread plate fixed points FP. The multi-sided support via springs results in a floating mounting of the retaining ring, which in particular allows tilting movement in all directions and thus favors movements of the user held in the retaining ring HR, the springs are set so that they only a small

Allow transverse movement and in particular a stop of the retaining ring to the fixed points FP or the ring segment is avoided. The fixed points FP can be parts of a ring segment that is fixed in itself, which is fastened to the retaining bracket HB.

In Fig. 9, an embodiment is outlined, in which the wobbling motion of the moving part is operated by a motor, for which the moving part in a joint MG, for example, in the inner ring of a gimbal mounted, and a protruding from the tread plate TP through the joint rigid nozzle GS below the joint MG motor to a circular motion, for example via a drive arm AG on a drive shaft AW, which is driven by a motor AM excited. The drive assembly is advantageously housed in a housing GM, the cover plate DP can also form a track LM for rolling the tread plate TP. The base plate GP forms a broad support base.

Fig. 10 shows a variant in which in a conventional manner, the tread plate does not roll with its outer edge on the base GP, but a track LI from the outer edge of the tread TF in the direction of the joint TG arranged inwardly staggered and formed, for example, by the upper edge of a mounted on the base GP mounting pipe socket. This avoids that body parts of the user or other persons between the edge of the tread plate and the base plate are clamped. As a further measure against risk of injury is indicated in Fig. 10 that between the outer boundary of the tread plate TP on the one hand and the base GP on the other hand, a circumferential flexible sheath, for example, a bellows BA is provided.

Fig. 11 shows a moving part, in which the retaining ring HR is held above the tread plate TP not by means of a single rigid strut but by means of an adjustable multi-part support means. The multi-part support device includes in the example shown two on laterally opposite edges of the tread plate TP in joints, such as ball joints, Gabelköp- fen GK or the like pivotally supported columns GS, which lead to a headband HB at the retaining ring HR. A third support TS is arranged substantially in the already described symmetry plane SE behind the retaining ring and in the example sketched length variable, in particular telescopic. The third support TS is also at least to a limited extent pivotally mounted on a fork head GK on the tread plate TP. By changing the length of the third support TS of the retaining ring is displaced substantially horizontally and the centroid of the area enclosed by the retaining ring surface can be displaced relative to the surface normal of the tread plate TP to the rear or front. In a further development, the three supports GS and TS can not lead directly to the retaining ring HR or the headband HB, but to a strut, along which in turn the retaining ring can be adjusted in height. Fig. 12 shows a plan view of a moving part of Fig. 11 with additionally indicated base plate GP. The supports GS advantageously extend in the vertical projection shown in FIG. 12 outside the half shell HS of the retaining ring. The joints GK are advantageously arranged entirely on the edge of the tread plate TP. The remaining reference numerals correspond to the similar components of the preceding embodiments.

In Fig. 13, a variant of a half-shell of the retaining ring is drawn, which is adjustable in width. For this purpose, the half-shell is divided into a left part HSL and a right part HSR, which are both adjustable relative to a holding plate HP, which is tiltably mounted on the headband HB, laterally adjustable and lockable by means of locking screws SH or the like in different positions. For a uniform adjustment of the width of the half-shell to both sides, the two halves HSL and HSR can be forcibly guided in the region of the holding plate HP for a symmetrical movement, for example by means of two gear rails coupled via a gear. An adjustment of the width of the half-shell can then z. B. also be done by rotation of such a gear.

Fig. 14 shows schematically a person standing on the treadplate TP in the use of the apparatus and illustrates the fixation of the user's body in the pelvic region and the mobility of the upper body and the arms.

15 shows an example of an embodiment of a training device with adjustable tilt angle KW of the tread plate TP relative to the base plate GP. For this purpose, in the example sketched in FIG. 15, a universal joint KG is mounted on the base plate GP, whose articulated arm ZS pivotable relative to the base plate about two orthogonal axes as a rod with several fixing holes, rack, threaded rod or as a similar linear member with position. is formed nierstruktur. A counter structure fastened on the tread plate TP, which can be displaced along the rack ZS, is designed, for example, as a sliding sleeve SH. By means not explicitly marked with locking elements and / or rotatable threaded elements, the position of the sliding sleeve SH can be set along the articulated arm in different longitudinal positions and thereby the tilt angle KW can be set variably. If the articulated arm has a tooth structure or threaded structure in its adjustment range, the counterstructure is advantageously designed to be rotatable about the articulated arm. For the rotation and a servomotor can be provided.

FIG. 16 shows an embodiment with a tilting angle KW adjustable according to the type of FIG. 45, which is drivable by a drive motor AM in the manner of FIG. The rack ZS, which is continued on the side facing the joint GL by a rod-shaped element GS, is held relative to the cover plate DP for performing the tumbling motion in a pivot bearing GL, which is held on the cover plate DP by means of a flange FL , In the example sketched, the drive motor AM, which is advantageously speed-controlled by a transmission, drives a drive pulley AS with which the rod-shaped element GS is coupled. Depending on the tilt angle KW varies the orientation of the rod-shaped element GS relative to the axis of rotation of the drive pulley AS and the distance of the coupling point between the element GS and the drive pulley AS, which may be considered for example by a slot-shaped guide in the disc AS.

The features indicated above and in the claims, as well as the features which can be seen in the figures, can be implemented advantageously both individually and in various combinations. The invention is not limited to the described embodiments limited, but within the skill of the art in many ways changeable.
