Elastic exercise machine

Description

The invention relates to an elastic exercise device according to the preamble of claim 1, as used in particular for sports or sports medicine purposes.

It is known to fasten elastic cords between two fixed handles of an exercise device (extender) and to pull the cords axially when practicing via the handles. By hanging a corresponding number of cords on the inside of the handles, the tensile force can be changed, but not the length of the cords and thus the entire exercise device. This would be necessary depending on the exercise or the person practicing.

For flat, elastic exercise bands that are increasingly used for training or exercise purposes, however, no handles are known, between which the e.g. would be less than 0.15 mm thick and up to 200 mm wide tapes. If such a band is gripped by a practicing person, e.g. to carry out an extension at chest height, then the person practicing must grip the band material properly so that it does not slip when the band is stretched. In addition, it is practically impossible to stretch the tape without distortion, so that a pattern present on the tape surface (see DE 200 13 074 U1) can change evenly over the entire bandwidth and can be observed in a visually concentrated manner.

For example, the physioband from Tilia GmbH, 87484 Nesselwang, is known, from whose exercise poster it can be seen that it is not readily possible to hold the band in a flat-open, distortion-free position. The practicing person is therefore more focused on clawing into the band than on the exercise performed with it. This exercise brochure or poster also shows that the loose physioband can be held together to form an endless loop using a clip, which is also included in the packaging for example, to be able to carry out appropriate arm or leg exercises in the suspended state of the loop-clipped band.

Such clips, such as those used to hold exercise bands together in a loop, are already known in different embodiments, but are always used for closing bags, bags, sacks, etc., e.g. in US Pat. No. 2,818,871, US Pat. No. 3,571,861, DE 2547 875 A1, US Pat. No. 4,296,529, US Pat. No. 4,523,353, EP 0 156779 B1 and WO 93/16930 A1. One-piece closure devices such as clips or clips for bags or hoses are thus known, which consist of two arms connected by a film hinge, which have interlocking clamping profiles on the surfaces facing one another in the closed state and, via a detent on the free arm ends in the closed Condition can be determined. When open, the arms are at an angle of max. 90 ° to each other. The end of the bag to be closed or the two ends of an exercise band to be connected are placed one on top of the other, transversely on one, usually lower arm, after which the second, mostly upper arm is pivoted onto the lower arm and pressed so that its interlocking longitudinal profiles Clamp any bag or tape material between them. The clip is held together in the closed state by a catch on the arm ends. This clip is therefore only used for closing or coupling, but not as a handle over which a train is exerted.

Also known from US Pat. No. 3,036,506 is a closure clip for the insulation bag of an underwater camera, with a channel-shaped forearm and a flat rod-shaped upper arm, the arms being connected in an articulated manner via an axle pin which transversely penetrates the two interlocking parts. The upper arm is held in place by means of a notch provided on the lower arm, and thus also the bag, by means of an eyelet which is pivotably attached to the opposite end of the lower arm. It is not known to use this clip as a handle. It is therefore an object of the invention to provide an elastic exercise device which enables safe, comfortable, versatile and concentrated handling and practice.

This object is achieved by an elastic exercise device with the features of claim 1. Advantageous embodiments of the invention are characterized in the subclaims.

Accordingly, the elastic exercise device has two clamping brackets as handles, in which at least one elastic element is fixed or releasably clamped to a predetermined length. It is thus in the course of a. B. exercise band (or a rubber rope or rubber hose) two clamps at the required distance of z. B.40 cm long perpendicular to each other, i.e. fastened transversely to the longitudinal or tensile direction of the tape. This allows the practitioner to grip the band on the two clamps and safely perform the appropriate stretching exercises. The known clips previously described, but also known buckles with clamping bolts can be used as clamping brackets, which on z. B. 40 cm apart from each other on the band clipped or clamped. The practitioner then grips the band via the two clip holders and pulls on them so that they are moved apart in parallel, whereby the band part clamped in between is stretched evenly in length.

It is advantageous if a gripping or holding element pointing in the band pulling direction is provided on the brackets. Two brackets are then attached to a band in such a way that the respective holding elements point outwards, making it easier to grip and in particular to hold the band under tension.

According to the invention, a rigid bracket, a flexible strap or loop such as a rope or cord, a central T-handle or ring or the like can be provided as the holding element. It is important - and only possible according to the invention - that when the tape is stretched and in particular when it is stretched, it is held over the holding elements. elements on the brackets, the band remains visible in its full width without distortion during exercises at chest height, so that the practitioner can change the stretching of a geometric pattern on the band surface according to DE 200 13 074 U1.

E.g. a rope holding element is provided, which is advantageously attached via an eyelet at the two ends of one side of the bracket, then the practicing person can hang the thumb of one hand in the respective loop formed and press the handles apart at chest height with arms almost extended , whereby the intermediate band is stretched accordingly. By simply gripping and pulling apart the full width non-slip band, which is hung over the thumbs, the band and holder are freely leveled around the two thumb pivot points. As a result, an extension can be practiced in which a largely distortion-free, i.e. vector-free longitudinal stretching of the band can be achieved. This effect is of course also achieved when using retaining rings.

According to the invention, a ball or a tube made of rigid or flexible material such as e.g. made of wood or plastic, slidably mounted over the central hole. If the holder is gripped and extended via the ball or the tube, the handles can also swing in without distortion.

A thumb gripping ring can also be integrated in the middle of the rope or cord of the holding loop, which can also be made of wood or plastic, for example. Due to the fact that the thumb gripping rings are much thicker than the rope or cord and have a solid, rounded gripping inner surface, swinging in on the thumb over the ring can also be easier and more pleasant than with the thumb directly attached to the rope loop. It can easily be seen that with a relatively thin design of the loop rope under load on the thumb, a relatively uncomfortable squeezing and cutting takes place, which is not the case with relatively thick thumb rings, the thickness of which can correspond to the height of the closed clamp holder. Accordingly, at least one geometric figure, such as an ellipse, rectangle or rhombus is provided on the band in the direction of stretching of the exercise band, which when stretched with a predetermined force, such as. B. with 1, 5 kg or 2 kg, form or result another predetermined geometric figure such as a circle or square. In this case, in or next to at least one of the geometrical figures, the corresponding elongation force specification, such as 1.5 kg or 2 kg, is applied in such a way that, for example, when training under elongation. B. a circle from an ellipse, the corresponding indication of z. B. 1.5 kg is very legible. Finally, two handles are attached to the tape at a predetermined distance and parallel to one another and at the same time perpendicular to the longitudinal extent of the tape, which hold the tape securely over its entire width. As a result, the exercising person does not grasp the band directly, but the handles attached to it, so that allergic reactions are optimally avoided and at the same time they can safely and comfortably stretch the band over the handles without distortion, without having to hold their hands directly on the bands in the Exercise concentration to be disturbed.

It is advantageous if a transverse rhombus pattern, a rectangle pattern or an ellipse pattern is provided on the exercise band, each of which consists of at least one rhombus, rectangle or ellipse pointing along its short axis in the direction of stretching, which is in a predetermined stretching situation are each deformed into a transverse square, normal square or circle. In this case, only one geometrical figure can be arranged in the middle of the band, or two or more identical figures can be applied symmetrically to the center of the band or along the entire band at a uniform spacing from one another.

However, it can also be particularly advantageous to provide at least two identical geometric figures of different dimensions adjacent to one another, to which different force specifications are assigned and which form the predetermined other geometric figure when the respective corresponding tensile force is reached, B. from an ellipse to a circle. You can in the middle of the band z. B. a pair of figures with z. B. two differently sized ellipses can be provided, or a plurality of pairs of figures can be provided or arranged in a center-symmetrical manner next to one another or over the entire length of the band with a uniform spacing of the pairs of figures. Of course, more than two figures of different dimensions and thus different load assignment can also be provided next to each other, with corresponding information on forces, such as. B. four differently wide or differently wide and high ellipses, designed for and labeled with 0.5 kg, 1 kg, 1, 5 kg and 2 kg or a fifth ellipse with 2.5 kg. So the exercise device can be used by different strong people for different exercises, e.g. B. for exercises while keeping a certain force constant or between different stretching loads constantly changing, i.e. intermittent exercises.

According to the invention, the handles can be directly molded or glued to the ends of the strap, or the strap can be permanently clamped or glued into the handles. Such an inseparable, firm connection of the band to the handles is advantageous if the band is always used by the same person or by persons of substantially the same size or strength for approximately the same exercises. So z. B. for a medium-sized exercise person to strengthen the shoulder and chest muscles a band length of about 30 cm optimal, in which the band is held at arm's length with arms outstretched and with z. B. 1.5 kg of stretching force is kept constant for one minute, for example, fully concentrated on the corresponding stretching figure.

In a particularly advantageous manner, the above-mentioned clamping clips, known as closure elements, can in principle be used as clamping brackets or handles, although these, according to the invention, have undergone essential, very advantageous configurations or shapes. Thus, on the one hand, the holding arms on the inside can have similar clamping profiles as the known bag clips. In contrast to these, however, they are no longer connected by a film hinge, which does not allow the two arms to be opened and left lying open in a 180 ° resting position, but usually holds the two arms at an angle of less than 90 °, which hinders the view of the clamping surfaces and thus an optimal insertion of the band. By connecting the two independent clamping arms via the bearing eyes and the bearing pin, the two holding arms can lie flat and tilt-free on a support in the fully opened, i.e. opened, state. Then the exercise band can be placed more easily and more precisely on one arm at right angles to the longitudinal extension of the arms. The second arm is then folded over the lower arm with the band resting thereon and pressed firmly onto the band, so that the closure on the arm ends, which can preferably be designed as a swivel bracket, is held.

It is advantageous if a spherical abutment is provided on the bottom of the clamping groove of the lower arm, on which, in the closed state of the clamping arms, the at least one web of the upper arm rests with the band in between. There are then also two upper clamping webs which are spaced apart from one another in such a way that they partially encompass the spherical abutment, as a result of which the band clamped in between is additionally deflected. As a result, the band is not only deflected in a V-shaped, but W-shaped manner, as a result of which a more secure clamping takes place and thus higher tensile forces can be exerted on the band via the handles without the band sliding out of the clamp holders of the handles.

The spherical abutment can be a soft elastic cord, which in the bottom of the groove e.g. is attached by gluing, the webs then being shorter and inelastic. The soft, elastic abutment ensures optimal non-slip clamping without the risk of damaging the belt by crushing.

Secure clamping is also obtained if the abutment is a semi-circular, rigid elevation at the bottom of the groove, while the two clamping webs are given a somewhat longer, elastic design, so that they are pressed on can be easily spread apart on the abutment so that the belt in between cannot be squeezed.

It is also particularly advantageous if the two arms of the clamp holder have relatively wide support bases in relation to their height and length, which e.g. 1, 5 to 5 times wider than the active inside of the arms. This gives a particularly wide contact surface of the arms, which is then in the open, opened state, for. B. lie on the table or floor without tilting, so that the tape can be placed on it in a correspondingly aligned manner. Even when swiveling and folding the upper arm onto the lower arm and pressing it there is no danger of the holder tipping over, which could cause the band to slip out of its aligned position. In addition, this support base can be curved and wider in the middle than at the ends. At the same time, an attractive shape with good handling is achieved.

Of particular advantage is also; if on the inside of the base edge of the lower arm, on which the tape is to be clamped, several markings such as grooves, lines, knobs or beads are provided at a uniform distance from the center, transverse to its longitudinal extent. This is possible in a simple manner, since the support bases protrude relatively far to the side from the central profile strips, so that essentially a T-shape of the arm is obtained. Thus, there is a relatively wide base edge on both sides, so that the markings are clearly visible the inside can be attached. The tape can thus be inserted and clamped exactly vertically and at the same time in a central orientation in the handle holder.

According to the invention, however, other clamping closure elements can also serve as the clamping bracket, such as the sliding buckle known for belts or belts. In this case, the material is held in a housing with a flat bottom, onto which the part to be clamped is inserted or pushed in, with a clamping roller which can be moved in the longitudinal direction and which acts against the pulling direction via lateral conical clamping guides of the housing. Of course, with this roller clamp it is also possible to attach the same holding elements as for the clip holder, i.e. of stirrups, rope or cord straps, with grip rings or grip balls.

With this buckle embodiment there is also the possibility of using elastic exercise devices of different embodiments, of course with corresponding shape adjustments.

When using non-exercise bands, the inside of the housing and the pinch roller are designed so that they both have a smooth surface. But you can also have a longitudinal or transverse profile for more secure clamping, z. B. in the axial direction of the roll grooves, corrugations or an anti-slip coating.

When designing the pinch roller holder for rubber cords, a groove profile must be provided in at least one of the two clamping elements of the holder, namely the housing base and the pinch roller, which allows several cords to be inserted next to each other so that a cord is positioned in each groove. It is advantageous if the groove or groove-shaped grooves are designed with a radius that is larger than the radius of the cords. However, it can also have only one of the two clamping elements, grooves or grooves, that is, either the housing base or the clamping roller. However, both clamping elements can also be equipped with grooves or grooves designed as mirror images of one another, these alignment or guide grooves or grooves being provided in a manner symmetrical to the longitudinal axis of the housing. This means that there is always a center symmetry and thus a force symmetry through the inserted elastic cords.

Finally, a flat comb with at least two, preferably three or more tines, into which the band is clamped, can be used as the clamping bracket. Of course, the tines should be designed at least as long as the bands are wide. In addition, a holding arm parallel to the tines is provided on the holding bar which carries the tines, on the turn A tether, bracket or ring, as described in the two previous basic embodiments, can be attached via tabs / eyelets or the like. Of course, here too it is important to ensure that the tape is to be attached in a manner that is center-symmetrical to the holder, for which purpose at least on the tines but also on the holding arm corresponding markings in the form of lines, beads or grooves pointing in the longitudinal direction of the train, are to be provided. Of course, not only tapes, but also cords can be held in place with this comb holder, whereby for the cords that cannot be traced flat on top of one another, cord grooves are to be provided on the narrow side of the first prong directly adjacent to the holding arm, into which the cords are hung can to maintain the center or force symmetry and at the same time prevent the cords from slipping in the transverse direction. Corresponding band guides can of course be provided on the tines of a comb holder which is always used with an exercise band of the same width. For example, on the first tines located directly behind the holding arm, there can be guide beads provided on the side surfaces, that is to say at the front and rear, and also an internal guide in the form of a bead or a knob. Guide grooves of the width of the band can also be provided in the tines on both sides.

In Fig. 1, an elastic exercise device 1 is shown, which consists of a known exercise band 2, on which two clamping brackets 3 are attached at the optimal distance for the corresponding exercise. It can be seen that this is an Elanet ^® tape, on the surface of which at least one row of a geometric pattern is applied. It can also be seen that the untensioned band motif 4 is here an ellipse that is stretched into a circle as a tensioned band motif 5 under predetermined tensile force. In the case of extension exercises, the exercise person can now evenly stretch the exercise band 2 clamped between the clamp holders 3 and visually and mentally follow the stretching process until the intended motif change occurs. This indicates that the tensile force or tension has been reached under which the band is to be kept constant during the exercise. This happens without cramped, direct cramping hands in the band, which prevents distortion in the band and premature signs of fatigue in the hands.

FIG. 2 shows an exercise device similar to FIG. 1, except that here the exercise band 2 as a geometric motif 4 has diamonds in the untensioned state of the band, which in the correspondingly tensioned state as motifs 5 become squares. In addition, a holding element 6 is provided on each of the clamp holders 3, which can be seen here as a stiff bracket which is attached to one long side of the holder. The exercise person can now easily grab the brackets on the brackets with their full fists and pull on the two brackets and thus on the belt. However, the exercise person can also hook in only the thumb 8 of their hand in a very effective manner, as can be seen more clearly from FIG. 3. As a result, the thumb acts as an axis of rotation, over which a free swinging takes place during the exercise, so that the two clamping brackets always align themselves parallel to one another, with even tension of the band 2 clamped in without slipping.

From Fig. 3 it can be seen that the brackets 3, between which the band 2 is clamped, wear flexible holding straps 7 as holding elements, in which thumbs 8 of the hands 9 of the exercise person are suspended. It can be seen how a leveling, correct alignment of the exercise device takes place through the suspension between the thumbs and thus allows a uniform, distortion-free stretching of the band.

4 to 12, the clamp holder is shown in its special design as a clip holder 10, in which the band 2 is securely clamped between two clamp arms which can be pivoted relative to one another, as will be described in more detail below.

4 shows how a holding loop 7 is fastened to the clip holder 10 by means of eyelets 11 attached on the longitudinal ends. The rope, cord or cord from which the holding loop 7 is formed is passed through the two eyelets 11 and ends in a thumb grip ring 12 in which the loop ends are securely attached. The practicing person now hangs his thumb 8 in the eccentric opening 3 of the gripping ring. It can be seen how the handles are leveled out, in which case the loop cord can also be shifted in the eyelets for the symmetrical alignment of the ring 12 to the holder and thus to the band.

5 shows the same view and the same embodiment as in FIG. 4, only that here a gripping ball 14 is provided as a gripping element on the unclamped holding loop, which is lined up on the loop cord 7 via its central bore 15. The exercise person now grips the holding loop 7 not directly, but rather via the gripping ball 14. The movement of the ball on the cord also causes the training device to swing in freely. Of course, instead of one gripping ball, several gripping balls of the same or different diameter can be lined up on the holding loop, or a gripping coil 16, as shown in FIG. 11, can be used.

From Fig. 6, which shows a cross section through a clip holder 10 in the closed tension state, it can be seen that the holder consists of a lower arm 20 and an upper arm 21 which interlock with one another through their correspondingly configured inner profiles and the interposed band 2 hold on tightly. In this case, a V-groove 18 is provided in the longitudinal section 19 of the lower arm 20, on the bottom of which a spherical abutment 17 is formed. The upper arm 21 has on its profile strip 22 two elastic webs 24 separated by a central groove 23. It can be seen that in the tensioned-closed state of the clip holder 10, the webs 24 stand up on the spherical abutment 17 in such a way that they are light are pressed apart and resiliently slide laterally on its circumference without queuing vertically or radially. As a result, the interposed band 2 is not pressed off as in a pair of pliers, but is only held elastically pressed between the webs and the abutment. The five deflection points along the belt ensure that the belt is held securely and without slippage over its entire length. This secure hold can also be done with tapes of different thicknesses because of the elastic webs if necessary, just spread apart more or less. Furthermore, it can be seen how the eyelets 11 are provided on the profile bar 19 of the lower arm 20, wherein it should be noted that the eyelet is pulled up so far to the upper edge of the profile bar 19 that the strap is as close as possible to the band 2 on the eyelet is attachable. Finally, marking beads 28 are provided on the inner base edge, as can be seen more precisely from FIGS. 8 to 11.

In the embodiment of the clip holder 10 shown in FIG. 7, a U-groove is provided on the profile strip 19 of the lower arm 20, in the base of which an elastic cord of circular cross section is inserted and z. B. is attached by gluing. In addition, the profile strip 22 of the upper arm 21 has two rigid webs 34 which are separated from one another by a groove 33. The webs 34 stand with their rounded end faces with vertical pressure on the soft elastic cord 30, slightly pushing it in. It goes without saying that the interposed band 2, which here experiences five deflections in a W-shape, is held extremely securely, but at the same time is elastically clamped without damage. The profiles and the elastic cord are dimensionally matched to one another in such a way that even the thinnest tape is held securely by gently pushing in the elastic cord. But even the thickest band, to which the strongest tensile forces are applied, is also held in place so as to be slip-proof or slip-resistant by pressing the elastic cord in a correspondingly stronger manner, determined by the thickness of the band.

As can be seen from FIG. 8, the lower arm 20 with the upper arm 21 can be pivoted via a hinge 35 with axis 36 or to min. Can be opened and closed by 180 °. At the other end of the lower arm 20, a pivot bracket 37, preferably made of spring steel wire, is provided, on which in turn a guide roller 38 or ball is rotatably mounted. In addition, the outer end of the upper arm 21 has a nose 39, via which in the closed state of the clip holder, that is to say in the pressed-on state of the upper arm on the lower arm, when the swivel bracket 37 is pivoted up, the guide roller 38 rolls in and holds the two arms. Finally, it can be seen how the marking beads 29 in on the inside of the base edge 27 uniform spacing from each other and at the same time to the middle of the arm, and like the two eyelets 11 are provided, in which the cord of the strap 7 is suspended.

Fig. 9, which allows a clear view of the top of the lower arm 20 through the broken away upper arm 21, illustrates in particular the width ratio according to the invention between the profile strip 19 with V or U groove 18 or 30 and the base 25. It it can be seen that the base 25 in its central greatest width is more than three times as wide as the profile strip 19. This provides optimal tilt resistance of the lower arm and also of the entire holder, in a situation lying on a flat base, such as this z. B. is the case when inserting the exercise band. In addition, the marking beads 29 provided on the inner base edge are on both sides of the profile strip 19 in the transverse direction of the clip, i.e. provided in a direction in line with each other in the direction of insertion of the tape. As a result, they allow the tape to be inserted easily and precisely and “guide” the human eye. Numbers or letters can also be associated with the marking beads 29, for example, arranged in mirror image, starting from the center outwards start counting large numbers, but simply pay attention to the left and right that the same letters or numbers or other symbols of the same type are visible on the edges of the tape, so that the tape can be quickly and precisely centered and vertical on the lower arm and thus be placed or aligned to the entire clip.

Fig. 10 shows the clip holder in the closed or about the hinge 35 in the folded state of the arms 20 and 21 and with the bracket 37 pivoted up, the guide roller 38 engaging over the nose 39 and thus firmly holding the two arm ends together.

11 and 12 show the holder 10 in the fully opened state over the hinge 35 and the swivel bracket 37 opened outwards. It can be seen that the arms 20 and 21 extend over their wide base 25 and also the swivel bracket 37 rest on a flat surface 32. In this tension-free, tilt-proof condition of the clip holder, the exercise band can simply be placed on the lower arm in the appropriate orientation, especially since the cross-marking beads 29, which are only provided on the lower arm, make it quick and easy to see where and how the tape is to be placed in the correct orientation, namely on the lower arm 20. If the tape is then properly placed on this, the upper arm 21 can be lifted from the base 32 via its outer end with the nose 39 and pivoted by 180 ° without any risk of tipping or folded over the lower arm. Then near the outer end of the upper arm is pressed towards the lower arm and the swivel bracket 37 with its guide roller 38 is clipped over the nose 39 of the upper arm. From Fig. 11 it can also be seen how a holding coil 16 is provided on the holding loop 7, which is provided in the center with a deep annular groove into which the thumb 8 can be hung.

FIG. 13 shows a handle according to the invention in the form of a clamping roller holder 40, as is known in a similar embodiment, for example as a closure element for straps or belts, ie for example as a belt buckle. As the basic element, it has a U-shaped housing 41, with a flat bottom 42 and lateral clamping guides 43, which are bent inwards again at their upper edge to form a conical guide bar 44. A pinch roller 45 is provided, the two pins 46 on the ends of which are stepped such that they are guided along the inside of the guide strips 44 when the roller is inserted between the pinch guide side walls 43, as can be seen in particular from FIG. 14. The band 2 is lying flat on the inside of the housing base 42 and on this in turn the guide roller 45 is inserted in the opposite direction of the holder, that is, on the inserted band inwards into the clamping guides 34, so that the band 2 is clamped between the housing base and the clamping roller. 13 also shows how two eyelets 11 are attached to the housing 41 in the pulling direction, through which a cord 7 is drawn, which in turn is provided with a thumb grip ring 12. 15 illustrates the initiation of the clamped state of the holder 40, the band 2 already being inserted here on the bottom 42 of the housing 41, while the clamping roller 45 already placed on the band is pushed in the direction of the clamping guides 43. In this state, for example, the housing 41 and the thumb ring 12 lie flat on a base without being pulled over the ring 12.

16 and 17 illustrate a next step of the clamp fastening by means of the holder 40, in which the roller 45 has already been moved so far into the interior of the housing that the roller 45 in the direction of the conically tapering clamping guide via the clamping pins 46 is pressed onto the housing base 41 and holds the intermediate band 2 in a clamping manner. It is known that in this state the clamping is increased with a stronger pulling action. From this figure it can also be seen that the housing 41 can be provided over its entire length with the clamping guides and instead of the holding loops on the housing a holding bracket 6 is formed.

17 to 19 show that the pinch roller holder can also be used advantageously as handles for holding elastic rubber cords, with channel-shaped flat grooves then being inserted securely on the inside of the housing base 42 in the pulling direction, that is to say the direction in which the cord is to be inserted 49 are provided, of course a central groove is provided, which is flanked in parallel by two or more further grooves 49.

18 shows essentially the same embodiment as in FIG. 17, namely the housing with a grooved housing inner bottom and a smooth roller 45 and a rubber cord 48 clamped between them.

19 also shows an embodiment in which not only the housing bottom 42 has grooves 49, but also the roller 45 has the same on its circumference Groove profile 49 has, like the groove bottom. It is not shown that the housing base 42 can also be designed to be smooth when the roller 45 is grooved.

Finally, FIGS. 20 and 21 show a last basic embodiment of the handles according to the invention, namely as a comb holder 50. From FIG. 20 it can be seen that the comb holder consists of a comb back 51, on which a plurality of approximately equal widths pointing vertically Prongs 52 and a wider holding arm 53 are provided with a corresponding, essentially equally spaced apart. On the outer side of the holding arm 53, two eyelets 11 are formed, into which a holding loop 7 is drawn. The length of the holding arm and tines are designed for the width of the belt 2, so they are at least slightly longer than the belt width. In order to ensure that the tape is inserted exactly in the middle and straight, markings 28 are provided on the flat sides of both the prongs and the holding arm in a symmetrical arrangement with respect to the central axis of the holding arm 53. B. numbers. In order to finally hold rubber cords securely over this comb holder, 52 grooves 49 are provided on the long sides of the first tines facing the holding arm. Naturally, a central symmetry in the arrangement is to be observed, in order, for. B. hang a cord in the middle and / or two off-center.

FIG. 21 shows how the elastic exercise band is hung around the first prong 52 adjacent to the holding arm 53 and then looped through the spaces 54 between the further prongs 52 in a double guide. It can be seen that the band 2, which is guided around several turning points under tension, is stuck between the tines.

22 also shows a holder 3, which can in principle be designed as a clip holder, clamping roller holder or comb holder and has a central eyelet 55 as a holding element, on which a gripping ring 56 is pivotably and slidably suspended. This gripping ring 56 can be designed as a normal ring or, like the gripping ring 12 from FIG. 4 or 13, as an eccentric ring. In conclusion, it should also be noted that the handles according to the invention are designed in particular for holding exercise bands and elastic cords, but can also be used successfully for making the bands and cords endless, if necessary. With appropriate exercises can also be done directly on the handle, the z. B. couples the two ends of an exercise band, pulled while the band loop is suspended.

23 shows a flat exercise band 2 in the unloaded state, on which a longitudinal center row of equally spaced rectangles 57 are applied. Within each rectangle 2, 1.5 kg, the expansion force data 58 is inscribed, under the influence of which the rectangles 57 are expanded to the squares shown in FIG. 24. The corresponding information of 1.5 kg is also very legible.

24 also shows a flat exercise band 2 in the unloaded state, on which a longitudinal center row of diamonds 60 spaced apart from one another are applied. Within each diamond 60, the stretching force 58 is also inscribed with 1.5 kg, under the influence of which the diamonds 60 are stretched to the transverse quad rates 61 shown in FIG. 26. The corresponding information of 1.5 kg is also very legible here.

27 shows a flat exercise band 2 in the unloaded state, on which a longitudinal center row of evenly spaced pairs of ellipses is arranged, each formed from a wider ellipse 62 and a narrower ellipse 63. Thereby, within each wider ellipse 62 With 1.5 kg, the expansion force specification 58 is inscribed, under the influence of which these wider ellipses 62 are stretched to the circles 65 shown in FIG. 28, while within each narrower ellipse 63 with 2 kg, the expansion force specification 64 is inscribed, under the influence of which they narrow Ellipses 63 are extended to the circles 66 shown in FIG. 29. 30 shows a short elastic exercise band 2, on the center of which only a rectangle 57 with the tensile force indication 67 is applied, while a handle 12 is firmly attached to both ends of the band.

The unstretched band 2 shown in FIG. 31 also has two fixed handles 67 at its ends, only that here three different geometric figures, each with different expansion force specifications, are applied in the middle of the band. There is a wider ellipse 68 with the specification 69 of 1 kg, a diamond 60 with the specification 58 of 1.5 kg and a narrow rectangle 57 with the specification 64 of 2 kg.

Finally, FIG. 32 shows how the band from FIG. 31 is stretched under the action of a force of 1.5 kg in such a way that the transverse ellipse 68 with the indication 1 kg is expanded to a longitudinal ellipse, the diamond 60 to a transverse square 61 and the narrow rectangle 57 is stretched to a somewhat wider rectangle. It can be seen that when stretching with 1.5 kg, the figure of a transverse square 61 corresponding to this tensile force is clearly visible with the corresponding tensile force specification, while the other two figures were not drawn into a clear elongated figure (circle or square).
