Definitions

  • the invention relates to an exercise device comprising a handle portion having a first handle and a second handle and between them a compression space in which an elongated resistance element made of a com- pressible elastic material is arranged, whereby the handles, which turn in relation to a pivot element, are so arranged that when they turn, they affect the volume of the compression space, whereby the resistance element is arranged to press together in proportion to the volume change in the compression space.
  • Various aids for more effective exercising are known.
  • various portable exercise devices have been developed for home, office, and travel use. Depending on their structure, such devices can be used in stretching, increasing muscular strength and in endurance training.
  • Known exercise devices include different bendable springs, stretch- able elastic bands, and various devices with handles to be compressed.
  • the drawback of known devices is that they are generally suitable only for one type of exercise, and difficult to use.
  • the strength cannot usually be adjusted, and if it can, adjustment is difficult.
  • an adjustable resistance is essential in view of the versatility, efficiency and sense of use of a device.
  • US 5,222,926 teaches a hand exercise device having an adjustable compressive resistance.
  • the device disclosed in the publication comprises arms, between which is arranged an arcuate spring made of a flexible material.
  • the spring comprises a space into which a separate strengthening device that yields under the effect of the pressing force achieved by the arms can be inserted for adjusting the pressing force.
  • the cross-section of the strengthening device varies in the longitudinal direction of the strengthening device, and thus its position in relation to the space in the spring can vary and thus affect the magnitude of the pressing force.
  • the drawback in the solution is that adjustment is difficult and the strengthening device complicates the use of the device.
  • the device has a very limited use since it is only suitable for exercising the hands.
  • US 5,833,580 and 5,529,551 disclose solutions in which the pressing force can be adjusted by arranging strengthening devices having different cross-sections into a compression space between the handles. The drawback in such devices is that the user has to carry along various strengthening devices in order to be able to adjust the pressing rigidity. These devices also have a very limited use since they are only suitable for exercising the fingers.
  • the exercise device of the invention is characterized in that at least one open longitudinal groove is formed in the resistance element on its outer surface, and that a strengthening piece made of an elastic material is place- able in said space for adjusting the volume change in the resistance element and the compressive resistance caused thereby.
  • the exercise device com- prises a resistance element arranged in a space in which a volume change takes place via a movement of the handles, and the resistance element resists said volume change by pressing together and thus receiving the pressing force generated in the exercise device.
  • the resistance element is a longitudinal piece, made of an elastic compressi- ble material, such as plastic, rubber or a mixture thereof.
  • the outer surface of the resistance element is provided with at least one open space, preferably a groove extending along the entire length of the element, in which space a strengthening piece can be arranged to adjust the compressive resistance of the element.
  • the strengthening piece to be arranged in the groove or the like can be used to affect the volume change directed to the element during compression, since the resistance element itself has to press together more when at least part of the capacity of the groove is filled by said strengthening piece.
  • Providing the element with a plurality of grooves and arranging the desired strengthening pieces in the desired grooves allows the compressive resis- tance of the resistance element to be adjusted. It is an essential idea of a preferred embodiment of the invention that the strengthening piece to be arranged in a groove or the like is made of an elastic material, which receives part of the volume change in the compression space.
  • a band is ar- ranged between the ends of the resistance element, the band together with the resistance element forming a closed loop.
  • the resistance element is made of two parts arranged at the ends of the band, and that the element parts can be connected to each other to form a closed loop.
  • the band is made of an extensible elastic material, such as rubber.
  • the resistance element of the invention can be applied to functionally and structurally very different training devices, in which an element is required to receive the pressing force achieved in an exercise as such or by means of a lever or other mechanisms in the device. Furthermore, the exercise device of the invention takes up little space and is light, and can thus easily be taken along on trips.
  • the exercise device of the invention can be made of plastic or corresponding materials, which makes its manufacturing costs very low. In addition, such a versatile and compact device is well suitable for fitness enthusiasts, for therapeutic rehabilitation, and in exercises carried out during breaks on the job and when travelling.
  • an elastic compressible structure refers to a structure that presses together via a predetermined pressing force and is substantially restored to its prior state once the force stops.
  • Figure 1 is a schematic side view of an exercise device of the invention
  • Figure 2 is a schematic partial cross-sectional view of an exercise device of the invention seen in the longitudinal direction of the resistance ele- ment,
  • FIG. 3 schematically shows the principle of an exercise device of the invention
  • Figures 4a and 4b are cross-sections of a part of a resistance element of the invention
  • Figure 5 is a partial sectional side view of the structure of a resistance element.
  • FIG. 1 is a simplified view of an exercise device of the invention.
  • the exercise device comprises a handle portion 1 , a resistance element 2, and a band 3.
  • the handle portion 1 comprises a first handle 4a and a second handle 4b, which can be pressed with fingers or, depending on the dimensions and design, for example between the hands or feet against each other.
  • the device can also be used in such a way that the first handle is placed against a suitable support surface, and only the second handle is moved.
  • the ends of the handles are preferably bent from their outer ends towards each other in the manner shown in the figure, so that the handle por- tion can also be used as a drawing handle.
  • the resistance element 2 is made of an elastic material, whereby it presses together when the handles are moved towards each other and the volume of the compression space consequently decreases.
  • the resistance element can be made of rubber, expanded plastic material, a combination thereof or some other suitable elastic material.
  • ends of the band 3 which, together with the resistance element, forms a closed loop.
  • the band is preferably of rubber or some other suitable material, whereby the unity formed by the elastic band and the resistance element can be used for exercising also without the handle portion.
  • the resistance created by the elastic band being stretched is utilized.
  • the resistance element can serve as a handle.
  • the band connected to the resistance element can also be used as a hanging or fastening member.
  • the exercise device of the invention can also be made for example by injection moulding from plastic and rubber materials, whereby it is light and safe and does not cause an alarm in security checks at airports.
  • Figure 2 shows a simplified view of an exercise device of the inven- tion.
  • the first and second handles 4a and 4b can be moved in the direction of arrows A against each other in relation to a pivot member 6.
  • the pivot member 6 can be a joint between the handles or for example a flexible portion created during manufacture, allowing the handles to move but not substantially resisting the movement of the handles. It is advantageous to use a pivot member comprising a pivot pin or the like, around which the handles are arranged to turn.
  • the handle portion 1 further comprises a compression space 5 in which the resistance element 2 is arranged.
  • the cross-sections of the compression space and the resistance element can vary, but preferably correspond.
  • the cross-sections of the compression space and the resistance element are pref- erably circular or oval.
  • the volume of the compression space decreases, whereby the resistance element in the space presses together to a degree corresponding to the volume change.
  • the figure also shows that the lower part of the compression space, the portion between the handles, is provided with an opening 7, allowing the movement of the handles 4a and 4b towards each other.
  • the dimensioning of the opening can be used to restrict the movement of the handles in the pressing direction A so as to eliminate the risk of pressing between the handles.
  • the size of the opening 7 is preferably at least such that the band connected to the resistance element can pass through it, if required.
  • the parts forming the portion between the handles of the com- pression space can be arranged to overlap.
  • the edge of the opening 7 comprises projections 8a and 8b, which point to the middle of the compression space and settle in a groove arranged in the longitudinal direction of the resistance element on its outer surface.
  • said groove restricts the movement of the handles away from each other and keeps the handle portion and the element in place in relation to each other.
  • the projections and the groove can be arranged at some other point than is shown in the figure, if need be.
  • the periphery of the resistance element is provided with grooves, in which strengthening pieces 9 are arranged.
  • the com- pressive resistance of the resistance element can be adjusted by arranging the desired number of strengthening pieces in the grooves or by leaving some grooves free.
  • the compressive resistance is further affected by the way the grooves and strengthening pieces are placed at the periphery of the resistance element, since the pressing force is not evenly distributed in the com- pression space.
  • the compressive resistance of the invention can also be applied to exercise devices, which, instead of pressing, are subjected to drawing B.
  • drawing B By means of a joint or other mechanisms in the device, the drawing is converted into pressing force C, which is received by the resistance element 2 of the invention.
  • Figure 4a is a cross-section of a part of a resistance element seen from its end.
  • the periphery of the element 2 is provided with grooves 10, in which strengthening pieces 9a, 9b can be arranged.
  • the dimensions of the grooves and the strengthening pieces may vary.
  • the posi- tions of the strengthening pieces at the periphery of the element can also be freely chosen. This allows the user to form different combinations and thus achieve a suitable resistance strength for each particular exercise.
  • the cross- sections of the strengthening piece and the groove may also vary according to the need, as Figure 4b shows.
  • the cross-section of the strengthening piece can be round, oval, rectangular, square or some other suitable profile.
  • the depth of the groove 10 can be so dimensioned that the strengthening piece partly extends outside the outer surface of the resistance element. In this case, inserting the element into the compression space creates a pre-resistance.
  • the strengthening piece can be a compressible or substantially non-compressible member. Different bars are placeable in the grooves 10, or, as is shown by a dashed line in Figure 1 , a band 3' connected to the resistance element can be inserted into one or more grooves. When a band connected to the resistance element is used as the strengthening piece, the strengthening piece is a fixed part of the device and cannot be mislaid, as is the case when separate strengthening pieces are used.
  • Figure 5 shows an alternative resistance element composed of two inter-connectable parts.
  • a first element 2a is connected to a first end of the band 3, and a second element 2b to a second end of the band. Consequently, during exercise, the band can be used either with the elements 2a and 2b interconnected as a device in the shape of a closed loop, or as a band in which the elements act as separate handles at the ends of the band. In the latter case, the band can be used for example as a skipping rope. With the elements 2a and 2b disconnected, the flexible band is longer and the resistance smaller. It is thus better suitable for certain exercises than an endless loop. Furthermore, it easier to fasten the band to for example the leg of a table or some other support point when no loop has to be threaded.
  • the first sleeve 11 a comprises a space into which a projecting connector piece 13 in the second sleeve 11 b can be inserted in direction D.
  • the counter surfaces of the sleeves are provided with connector elements, such as a groove 14a and a projection 14b.
  • a threaded or bayonet connection and other feasible suitable connector structures can also be used for connecting the element halves.
  • the figure shows no grooves arranged for adjusting the pressing force.
  • the pressing force can also be adjusted by placing the element halves in the compression space, shown in the figure by dashed line 5, at a suitable distance E from one another, whereby only the desired portions of the halves receive compression in the space.
  • the strengthening pieces can be used to place the halves at a given distance from one another in advance, and then arrange the compressive resistance in the compression space.
  • the compressive rigidity of the resistance element can be so adjusted that the resistance element is provided with at least one cavity substantially in its longitudinal direction, or a hole extending through the resistance element, whereby a strengthening piece 9d is placeable in said cavity or hole in the manner shown in Figure 4a to adjust the volume change in the resistance element and the compressive resistance caused thereby.
  • the exercise device can be used for preventing rheumatic diseases or diseases in motor muscles, for rehabilita- tion, interval exercises and, naturally, for training. It is practical in exercises during breaks at work and during travelling. It can be used for example on trains or long flights for quite versatile exercises to elevate blood circulation and to relax static muscular tension. It can also be used for massaging. Holding the rubber bands by the hands and rolling the grooved resistance element for example between the legs and the floor, stimulates tired legs.
  • the handle portion is suitable for use as a drawing bar for example when the elastic band is used for rowing movements.
  • the structure of the handle portion may vary to a great degree from what is shown in the figures, and does not have to be intended only for movements by the hands, but the handles can also be so designed that it is suitable for versatile exercises of the legs.
  • the grooves on the outer surface of the compressive resistance can be used for adjusting the length of the band connected to the element.
  • the band is place- able in the grooves, which allows its length to be adjusted so as to be suitable for each particular exercise, and, with the band inserted in the grooves, it does not press the user's palm.
