Abstract

  The present invention relates to exercise equipment for training upper body muscles by mimicking the exercises performed in connection with paddling. The exercise device of the present invention has a movable movable handle connected to at least one energy storage unit (5). The energy storage unit is preferably constituted by an elongated elastic element made of an elongated extensible material. When using exercise equipment, the handle moves in the axial direction of the equipment, thereby storing energy in the energy storage unit. With continuous movement, the stored energy is released from the elongated elastic element and returned to the moving person. The use of the exercise apparatus of the present invention is more effective for training the upper body muscles compared to the use of conventional walking poles. Furthermore, a favorable side effect that tension on the leg muscles is reduced is also obtained.

Description

TECHNICAL FIELD The present invention relates to certain types of exercise equipment primarily intended for supplemental training in conjunction with walking. More specifically, the present invention relates to an exercise device with a movable handle attached to at least one energy storage unit. When using the instrument, the handle is moved in the axial direction of the instrument, thereby storing energy in the energy storage unit. Through continuous exercise, the stored energy is released from the energy storage unit and returned to the man in motion.

Technical background When the lower body muscles are mainly trained, for example, walking, it is more efficient to train the upper body muscles from the viewpoint of training. Previously, pedestrians were limited to the use of different forms of gymnastics or regular ski poles, canes, weights and similar tools when trying to increase upper body muscle movement.

  Starting with Finland, the use of specially developed walking poles with walking has become increasingly common since the late 1990s. As a result of the use of walking poles, exercise proved positive in giving improved training results and studies showed an efficient improvement of between 10-30%. It has the disadvantage that pedestrians still do not perform effective dynamic exercise of upper body muscles with walking.

  The disadvantage of existing walking poles is an efficient energy storage device that uses the energy generated by the upper body muscles, and then returns the energy after storage to improve the kinetics for more efficient upper body muscles. They are not equipped with energy storage devices to achieve the desired movement.

  Paddling as a training method has proven to be an excellent way to train upper body muscles. It is therefore an object of the present invention to provide an exercise apparatus that trains upper body muscles to a greater extent than conventional walking poles.

Prior art Devices such as poles and similar devices containing elastic elements are already known. A shock absorber for a pole comprising at least one externally arranged spring applied to the lower part of the walker is described in patent application GB 2359498. When the walker is pushed against the ground, the spring is compressed, creating a cushioning effect. The elastic force of the elastic element can be selectively changed. This device includes an adjustment mechanism for adjusting the length of the pole. This pole is significantly different from the present invention.

  An accessory to different types of walker, which consists mainly of a presser spring placed outside the lower part of the pole, is described in patent application GB 2340402A. The structure consists of a presser spring fitted between the inner and outer tubes. During use, the spring is compressed, thereby creating a cushioning effect. This invention is greatly different from the present invention.

  US Patent Application No. 5484361 A discloses a spring loaded ski pole associated with skiing for improved training effects. This design includes a presser spring placed in the cap at the top of the pole. The design is held together by a rod that is centered in the spring and connected to the top of the cap and attached to the bearing at the top end of the pole. The cap is disposed proximate to the handle. Paul is primarily intended for upper body muscle training. The structure differs significantly from the present invention in that it does not include a handle that can be moved to any greater degree along the length of the pole.

  In international patent application WO 03034859 Al, shock absorbers are disclosed for example for canes, ski poles, trekking poles and the like. This shock absorber consists of a spring package arranged between two slidable members inside the pole. The spring package consists of a helically shaped presser spring along a cylindrical member of elastomeric material. This design constitutes a shock absorber, which is significantly different from the present invention.

  Swedish patent SE 522840 describes poles used on soil, snow and ice surfaces. This design consists of an outer tube and an inner tube, is telescopically movable and can be locked to a length suitable for the pole. In addition, this design includes a handle at the top of the pole and also includes a wrist hold adapted to the handle. The telescopic inner tube lock is housed in a spring system that provides some elastic energy to the inner tube inside the outer tube when the pole is struck by the ground / snow / ice. The invention is characterized by an inner tube and an outer tube of approximately the same length, which have a specific shape that allows the pole to have a reduced relative weight in the downward direction. Furthermore, the invention is characterized by an upper pole piping shaped to have a reduced diameter that fits a suitable relatively thin handle. The design described in SE 522840 is significantly different from the present invention.

  Even though each of the above designs functions for those purposes, none of them are intended as exercise equipment associated with walking and mimicking the movements that occur during paddling, as in the present invention. In addition, any of the above designs are movable with respect to the length of the exercise equipment, allowing it to store energy, release it, and return it to the exercising person, thus providing more efficient training Does not include a handle connected to at least one of the energy storage units.

  Please refer to FIG. The basic concept of the exercise device 1 is shown by the present invention. The exercise device is comprised of an elongated member 2 of a suitable material such as plastic, composite material, metal material, or similar material. Preferably, the elongate member is a round cylinder or the elongate member has an oval, half-circle, triangular, square, polygonal or similar cross section. The elongated member is most suitably made from a solid or hollow material. A handle 3 is attached to the elongated member 2. This is movable in the axial direction of the elongated member.

  A stopper 4 is attached to one end of the elongate member in any suitable manner that couples, for example, an adhesive, push-in, bolt, screw wing plate or other member. The stopper 4 further serves to stop the upward movement of the handle shaft and prevent it from detaching from the elongated member. The shape of the stopper further allows a pole-shaped exercise device to be used as a fixed pole. The stopper can be made in many different variations and shapes. For example, the figure shows a stopper in the shape of a knob.

  The handle 3 is connected to at least one energy storage unit 5. The energy storage unit is connected to the elongated member 2 by, for example, an attachment 6. Alternatively, the attachment 6 can be arranged at a different location inside the elongated member in the case of being hollow in addition to the one shown in the figure. The energy storage unit 5 is not limited to the schematic embodiment and arrangement shown in FIG. The energy storage unit 5 can consist, for example, of an elongated elastic element, an air unit, a spring or another energy storage unit. The energy storage unit can quickly store energy and return the energy to the handle 3 quickly.

  By applying a force to the handle 3, the handle slides along the elongated member 2, thereby storing energy in the energy storage unit 5. When the force on the handle 3 is reduced, the energy stored in the energy storage unit is released, thereby returning the handle 3 to its original state.

  In FIG. 1, the handle is in its upper end position. In FIG. 2, the handle has been moved partially along the elongated member. In FIG. 3, the handle has been moved to the bottom.

  Reference is made to FIGS. A first embodiment of the exercise device is shown. Like the previously described variations, the exercise device includes an elongated member 2 and a stopper 4 disposed on top of the exercise device 7. In the figure, the stopper consists of a knob. The energy storage unit is made of at least one elastic element 5 in this variant. The elastic element is most preferably made of an elastic rope, spring or similar rubber product, or other suitable elastic material. The elastic element preferably has a circular, square or rectangular cross section. The elastic element 5 is fitted on the handle 3. In its simplest form, it can be constituted by a tube of an appropriate length attached to the elongated member 2. The shape of the inner side of the handle 3 is chosen to be in a form that essentially corresponds to the outer shape of the surrounding elongate member. A space for an elastic element should be provided between the elongated member and the handle. A bearing can be used to attach the handle to the elongate member so that the handle can be easily moved axially along the length of the elongate member. The bearing can comprise a known gliding bearing. It is configured inside the handle in the simplest form. The bearing can consist of a bearing in the form of an inset (not shown) that fits inside the tube. Furthermore, the bearing can comprise other known types of bearings for axial bearings. The handle is preferably made from a suitable material, such as some plastic, composite material, metal material or other suitable material. By applying a force to the handle 3, the handle slides along the elongate member, thereby storing energy in the elastic element 5 during the simultaneous extension of the elastic element. When the force is reduced, the stored energy of the elastic element is released, returning the handle 3 to its original state.

  A wrist strap 8, or the like, can be attached to the handle. The wrist strap 8 is intended to facilitate handling of the exercise equipment and improve handling of the exercise equipment. In addition, the wrist strap 8 provides improved movement of force from the exercising person to the device and vice versa. The size of the wrist strap 8 is fixed or can be appropriately adjusted by the user's hand.

  A tip 9 can be attached to the lower end of the pole in order to provide a good grip on hard surfaces such as tarmac, concrete or rock. It is made from hard materials such as Wolfram, some form of carbide or hard metal. For use in snow, the pole can easily be fitted with a snow disk or snow ring (not shown in the figure).

  FIG. 6 shows another design in which the elongated member consists of two members and is hollow. The elongate member consists of an inner 10 and an outer 11 profile material that can be plugged into each other. The locking mechanism 14 has a known mechanism, and can connect the inner profile material 10 and the outer profile material 11 in a nesting manner so that they can be firmly connected to each other. Alternatively, the length of the exercise device can be adjusted in other ways. For example, the tube has continuous holes (not shown) that fit together and the pole-like device is brought to the desired length. After length adjustment, the outer and inner tubes are locked together by a locking pin or the like.

  At least one elastic element is attached to the tip 13 at the lower end 14 of the tube, from which the elastic element extends along the tube from the tip to the upper end 7 of the tube and further out of the tube through the opening 15 to the handle 3 extend. The handle is attached to the elastic element using a knot or some kind of attachment element. It is shown in the figure how the elastic elements are arranged along at least one pulley 16. The pulley is attached to the upper end of the elongated member and connected to the opening 15. The distance between the axis of the elongated member axis and the center of rotation of the pulley can vary significantly. The arrangement of the pulleys relative to the axial direction of the elongated member can vary significantly. Furthermore, the diameter of the pulley can be freely selected according to the specific design of the exercise equipment.

  FIG. 7 shows a variant of the invention. This includes an elongate member 2 and at least one elongate elastic element 5 extending therethrough, one end of which is connected to the tip 13. The other end of the elongated member is fixed to the rope 17. The rope exits from the opening in the elongated member 2 and extends to the handle along at least one pulley 16. The rope is attached to the handle in an appropriate manner, for example by a knot or some known attachment element. Alternatively, the rope can consist of wire or the like.

  A fourth embodiment of the present invention is shown in FIGS. The figure shows that the handle 3 extends along the length of the elongated member 2 from the stopper 4 at the upper end (in this embodiment, the stopper 4 comprises a pulley 6) to or above the tip 13 at the lower end of the elongated member. Indicates whether it will grow. Four elastic elements 5 are attached to the handle and these extend from the tip to the pulley and handle 3 inside the tube. The elastic element is preferably constituted by a rubber rope or the like.

  In FIG. 10, a fourth embodiment of the present invention is shown. In this design, one end 18 of the handle 3 has an extended attachment 19. This attachment is intended for connecting the elastic element 5 with the help of the mounting element 20. The attachment 19 can also be attached to the upper end (not shown) of the handle 3. Alternatively, it can be attached at different locations (not shown) along the handle. The extended attachment 21 is attached to the pole at the upper end of the elongate member by a suitable attachment method, such as a mounting element 22 comprising a lock pin, screw wing plate or other equivalent method. Preferably, the attachment comprises a bent tube. The elastic element can be attached by a lock pin, a screw wing plate or other similar method. Alternatively, the elastic element can run through the attachment in and out of the elongated member.

  A different embodiment of the arrangement of the elastic elements 5 is shown in FIG. In this embodiment, the attachment 23 is connected to an appropriate portion of the profile material 11 outside the two-part elongated member. At least one elastic element 5 is attached to the attachment. The other end of the elastic element 5 is attached to the handle 3. The elastic element extends from the attachment 23 to the handle 3 via a pulley 16 attached to the upper end of the exercise apparatus in the axial direction of the elongated member and having a radial bearing.

  Figures 12 and 13 show how a locking device 46 is provided to the exercise apparatus. Thereby, the handle 3 is attached at the upper end 7 of the elongated member 2. The locking device consists of a locking arm with a bearing 24. The bearing is attached to the handle in any suitable manner, such as a mandrel 25, or a split pin, a screw wing plate, or the like. FIG. 12 shows the locking device in the released state. FIG. 13 shows how the locking arm 24 is directed to a position above the upper end 7 of the elongate member 2. This lock allows the exercise apparatus to be used as a conventional cane. In addition, a wrist strap (not shown) can be attached to the handle.

  FIG. 14 shows a seventh aspect of the design of the present invention. Here, the handle is configured in the form of a globe 26. The glove is attached to at least one energy storage unit in the form of a rubber rope or thread or similar elastic material in a suitable manner such as sewing. When training with an exercise device equipped with a handle in the shape of a glove, the elongate member is grasped with the aid of the glove 26 and the glove slides up and down the elongate member when training with the instrument. When returning upward, the glove hits the stopper 4.

  FIG. 15 shows a variation of the arrangement of the pulleys. Preferably, the deformation consists of a hollow elongated member 2 on which the handle moves. A resilient elastic element is attached to the handle. From the handle, a resilient elastic element extends onto the pulley 16. The pulley is attached to the attachment 27 by a mandrel having a bearing 28. The elastic element then enters the elongated member 2 and falls down to an attachment or other attachment device (not shown) in the form of a chip. The elastic element is for example attached to a chip (eg 13 in FIGS. 6 and 7).

  FIG. 16 shows how the chip is made from a combined design 29. The combined design 29 consists of a bowl-shaped member 30 that moves within a ball-shaped member 31. The ball-shaped member can be provided in the form of a dipping shoe 32 that provides a larger contact surface in a flat, circular or similar shape. This design has the advantage that it provides a quieter walk and can be used with reduced adverse effects on the underlying surface. FIG. 16B shows a variation of the tip consisting of the aspirator 33. The aspirator 33 is particularly suitable for indoor use. The bowl-shaped part 31 can be provided with a fitting (not shown in the figure) for the attachment of at least one elastic element.

  Refer to FIG. This shows how the sensor unit 34 can be connected to the exercise equipment. The sensor unit 34 connected to the movable handle 3 senses the pulling force of the elastic element 5. The sensor unit 34 based on known technology can include devices for storing, processing and transmitting information to a PC or the like.

  FIG. 18 shows a cross-sectional deformation of the elongated member 2. In a variant, the elongated member 2 is shaped such that at least one track 35 extends over part or all of the length of the pole (four tracks are shown in the figure). The handle 3 is also shown in the figure.

  FIG. 19 shows a pre-tightening device 36 to allow normalization of the force required to stretch the elastic element. The pre-tensioning device is adjusted so that the elastic element is tightened to an appropriate level according to the requirements of the trainer. The design consists of an elongated member 2 to which a movable handle 3 is attached. A preliminary tightening device 36 is attached to the movable handle. On top of this, at least one elastic element is mounted. The elastic element runs in the elongate member 2 through the opening 15. The other end of the elastic element is attached inside the long member to the tip (not shown in the figure) at the lower end of the pole. In addition, the pole is provided with an upper fixed handle 37. The pre-tightening device consists of a coil 38 attached to a mandrel with a bearing 39. A catch wheel 40 is attached to the mandrel 39 and is locked by a catch 41. By turning the handle 42 located on the mandrel with the bearing 39, the elastic element can be pre-tightened to a level suitable for the trainer.

  FIG. 20 shows an eighth aspect of the design of the present invention. Here, the elastic unit comprises a pneumatic energy storage unit 43. The pneumatic energy storage unit 43 is constituted by some kind of pressure cylinder 44 inside the pole which, for example, takes advantage of compression of air or a similar medium to obtain an elastic effect. In connection with the downward movement of the handle 3, an overpressure is created in the pressure cylinder. Excess pressure accumulates in the pressure vessel. It is connected to the pressure cylinder.

  Figures 21-22 show an exercise device having two upper handles. One fixed handle 37 further functions as the stopper 4. Furthermore, it has a movable handle 3 which is movable along the outer profile material 11. As described above, the design provides a movable handle connected to at least one energy storage unit (not shown in the figure) according to some of the previously described designs. This design has the advantage that if an upper handle is used, it can be used as a “normal” cane.

  The exercise apparatus is nested, and the inner (lower) profile material 10 is extensible with respect to the outer (upper) profile material 11. The outer profile material is locked to the inner profile material by the locking device 12. A fixed handle 45 is provided at the lower end of the upper profile material. In its simplest form, it can be constructed by wrapping tape or the like. A handle 45 is provided in the lower part (inner profile material) 10 of the exercise apparatus. In its simplest form, it can be constructed by winding a tape. In addition, the exercise equipment can be provided with a foot grip 46 which allows the foot to be placed and secured to the ground.

  FIG. 23 shows an exercise device provided with a weight 47 at its upper end. It also functions as a stopper. The weight can be placed so that its center of gravity substantially coincides with the center of the pole axis. Alternatively, the center of gravity of the weight can be outside the axial center of the pole. The weight can be configured so that it is fixed with respect to the center of the pole axis or can be adjusted so that the center of gravity of the weight is at the center of the pole. In the figure, a hand is drawn holding a movable handle 3 which is connected to an elongated elastic element 5. An elongated elastic element is also connected to the upper end of the elongated member 2.

A description of the use of elongated members in connection with movement.
When training with an exercise device according to the present invention, a unit of equipment is held in each hand. While walking, the devices are moved so that they move forward in order. Training with an elongated member can be described as the sequence described in FIG. When exercising with exercise equipment, the handle will show a movement corresponding mainly to the bold line in the representation of the figure. The sequence describes the movement of the elongated member during the motion cycle. The exercise apparatus is lifted forward and moved (vibrated). The equipment is fixed to the ground at an appropriate angle depending on the length of the exercise equipment and the height of the person being trained. When the pole approaches vertical, the movable handle is pushed downward by the pedestrian, thereby storing energy in the energy storage unit.

  When the pole passes a line perpendicular to the pedestrian, the pole's tilt will increase accordingly. In this connection, the handle is adapted to move upward along the elongated member in the direction of the stopper at the top end of the pole while releasing energy from the energy storage unit. The force from the energy storage unit will cause the body to push forward when the pulling hand is held in a straight line. Depending on the length of the exercise equipment relative to the height of the person being trained, at some angle the pole will not be able to contact the ground.

  In summary, FIG. 24 shows a large dynamic variation, resulting in a rested and extended position, acting on the extended hand to force the device back to the user. Through this procedure, the device helps to relieve leg muscle stress and at the same time push the body forward. Through this procedure, a movement pattern similar to that used for paddling is achieved.

  Figures 25-43 show how exercise equipment can be used for different types of training. When training according to the figures, the exercise equipment is preferably used as described with respect to FIG. When using exercise equipment, the outer profile material 11 and the inner profile material 10 are not locked together by the locking device 12 and can be moved independently of each other.

  Figures 25-26 show how the pole can be used for upper body muscle training. The exercise device is held by an upper fixed handle and a movable handle. The handles are pushed apart separately. Figures 27-28 illustrate how the lower part of the pole can be gripped and moved in a similar manner. Figures 29-30 illustrate how to grasp the movable handle with one hand. FIGS. 31-36 illustrate different training operations using exercise equipment.

  Figures 37-40 illustrate how a trainer can use exercise equipment to sit and train in a chair. The figure shows long movements when non-shortening exercise equipment is used.

  Figures 41-42 illustrate how exercise equipment can be used when a trainee trains on the knee. The trainer depresses the handle and moves axially along the elongated member. Alternatively, several other handles can be used to achieve a result equivalent to the previously described figures.

  While several preferred designs have been described in detail, variations and modifications within the scope of the invention will be apparent to those skilled in the art. Moreover, it is recognized that all such matters are included in the technical scope of the present invention. For example, elastic elements, elongate members, etc. can be designed according to many different variations that will be apparent to the average expert in the field. Further, the particular design of the present invention can be combined and varied with many different variations not described in this patent application, all of which are included in the present invention.
