Exercise tool

Description

[0001] The present invention relates to an exercise tool according to the preamble of appended claim 1.

[0002] That the at least three pillars are rigidly interconnected only means that they have to keep a fixed distance to each other, which could be obtained for example by being separately fixed on the same plate or on another carrier or even in a said ground, such as a floor.

[0003] The invention relates to exercise tools of the type mentioned above for all types of exercise, and/or physical activity, everything from exercise of physically healthy people in the form of exercisers or competitive athletes to rehabilitation training of people with reduced physical ability or fear of movement, for example due to an accident, injury or the like. Also play-related exercise is included, especially for kids in preschool or school.

[0004] An exercise tool of such a type is already known through the documents US 7 309 303 and FR 2 947 595 A1. In document US 7 309 303 an exercise device having pillars and bars is disclosed. Furthermore the exercise tool or exercise station disclosed in FR 2 947 595 A1 is intended to have different exercise tools, such as expanders, secured to the bars and beams thereof, but it is nowhere in that document mentioned that the bars and the pillars may be so arranged that exercise is to be carried out by entering and exiting an inner room defined by the pillars and the bars. However, the construction of this exercise station makes it possible to obtain offering of such an exercising possibility which is the reason for placing this feature in the preamble of appended claim 1.

[0005] Thus, the invention is directed to an exercise tool of the type defined in the preamble of claim 1, i.e. which allows forming of a said inner room and enables movement of the bars between different positions, so that the exercise possible in that tool may be made efficient and by simple means be adapted to the size, ability and other desires, such as degree of difficulty and effort, of the person to use the tool for training.

SUMMARY OF THE INVENTION

[0006] The object of the present invention is to provide an exercise tool of this type which offers improved possibilities to carry out efficient exercise therein with respect to such exercise tools already known.

[0007] This object is according to the invention obtained by providing such an exercise tool with the features listed in the characterising part of appended claim 1.

[0008] Thus, by the new approach to arrange a centre pillar in said inner room and the offering of the possibility to arrange bars between this centre pillar and the pillars defining said inner room, the range of training activities possible to carry out in the exercise tool will be considerably increased. This relates especially to possibilities to climb around in and to hang in the tool. Thus, an exercise tool with the features defined in claim 1 will be quite different than any other exercise tool known and provide a possibility to carry out other type of training than known exercise tools.

[0009] According to an embodiment of the invention said bars have a strength allowing a person exercising in the tool to stand on or to hang in the bars. The possibilities for variations of the exercise in the tool increases by that.

[0010] According to another embodiment of the invention the exercise tool comprises four said pillars configured to form a respective corner of said inner room. Four pillars are suitable for obtaining a space-efficient exercise tool with a said inner room of suitable size and possibility for varying exercise in the tool. The four pillars are then advantageously positioned in the stand in such a way that they form rectangular corners of the inner room, and each of the four pillars may then be positioned at the same distance to the both adjacent pillars so as to provide said inner room with a square bottom surface, which then also enables use of equal bars regarding the length between the different pillars.

[0011] According to a further embodiment of the invention the third engagement members of the centre pillar comprises bottom holes facing a respective pillar defining said inner room for receiving an end of a said bar, the latter pillars have through-holes aligned with said bottom holes for bringing a bar through these and to and into the bottom holes of the centre pillar, and the through-hole has an inner stop configured to require a lifting of the bar end in the through-hole for withdrawal of a bar from the position between the respective pillar and centre pillar in said exercise mode of the tool. This means that the bars very easily and fastly can be moved between different positions at various heights between the centre pillar and the other pillars and still be held safely in place in the respective positions. The or those persons exercising in the tool will thereby not experience it as hard work to change the appearance of the tool for changing the degree of difficulty of an exercise motion or prepare the tool for a different exercise motion.

[0012] According to another embodiment of the invention said engagement members of the pillars comprise recesses configured to receive ends of said bars. Said engagement members of pillars and the engagement members of bars interacting therewith are by that advantageously configured to require lifting of a bar to remove it from the pillars, once a bar is positioned between two pillars in said exercise mode of the tool, which results in that the bar is effectively being held in place by means of the gravity. According to a further development of this embodiment of the invention the end of a said bar is also elliptically formed, which makes it possible to secure it by twisting it so that it fastens in the recesses.

[0013] According to another embodiment of the invention said first engagement members comprise recesses in the form of grooves in the respective pillar, said grooves being open so as to allow introduction of an end of a bar therein while moving the bar transversally to its longitudinal extension. The bars may by that easily be put in place between two pillars and be removed therefrom. According to a further development of this embodiment said grooves have a bottom with at least one portion sloping in the direction of introduction of a bar end therein for retention of the bar end in said use mode by means of the gravity, and in the embodiment mentioned above also by means of the ellipticity.

[0014] According to another embodiment of the invention the pillars of the stand have a height of 1.5 - 3 meters or 1.8 - 2.5 meters. This together with providing the pillars with engagement members for enabling arrangement of said bars at 5-30 or 10-25 different heights is suitable for an exercise tool with an attractively small space requirement and great opportunities for variation of the exercise therein.

[0015] According to another embodiment of the invention the bars and/or the pillars are made of wood or made mainly of wood, which is a suitable material regarding costs, strength, reliability and appearance of an exercise tool of this type.

[0016] Further advantages as well as advantageous features of the invention will appear from the following description.

DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION

[0018] The exercise tool 1 shown in Fig. 1 comprises a stand 2 with five parallel pillars 5-9 mutually rigidly interconnected via a plate 3. The pillars are via suitable securing means 10 such as mountings and screws secured on the plate 3 functioning as support means for arrangement of the stand on a ground with the pillars extending vertically. The pillars 5-8 are corner pillars, each positioned at the same distance to the two adjacent pillars so as to provide an inner room 11 defined by the pillars with a square bottom surface on the plate 3, while the pillar 9 is a centre pillar arranged in said inner room 11.

[0019] The pillars have the same height, for example 1.5-3 meters and here about 2.2 meters. The stand is stabilized at the top by beams 12, 13 connecting corner pillars diagonally arranged to each other and to the centre pillar.

[0020] The tool has a plurality of bars, of which only two 14, 15 are shown in Fig. 1 for illustration purpose but can be significantly more to the number, such as easily 10, 20 or more. The bars are configured to each extend between two of the pillars.

[0021] Each corner pillar 5-8 has a plurality of, here more exactly 20, first engagement members 16 (see also Figs. 2 and 3) arranged at different heights along the respective pillar and both ends of the bars have second engagement members configured to interact with said first engagement members in order to hold the bars removably arranged between the pillars in an exercise mode of the tool. Said first engagement members more exactly comprise recesses in the form of grooves 16 in the respective corner pillar, which grooves are open in one end 18 so as to allow introduction of an end portion 17 of a bar 14 therein while moving the bar transversely to its longitudinal extension. The groove 16 has a bottom 19 with at least one portion sloping in the direction of introduction of a bar end therein for retention of the bar end in said exercise mode by means of the gravity. The end portion 17 of the bar further has an elliptical cross-section with a length of the shortest axis of the ellipse corresponding to or being smaller than the width of the groove 16 with up to some millimetres, which means that the bar has to be "correctly twisted" for being able to be inserted in the groove. This ellipticity of the end portion 17 of the bar assists the gravity to efficiently retain the bar in the exercise position.

[0022] The centre pillar 9 (see especially Fig. 3) has third engagement members in the form of bottom holes 20 facing a respective pillar 5-8 defining said inner room 11 for receiving an end of a bar 15. The corner pillars 5-8 have through-holes 21 aligned with said bottom holes 20 for bringing a bar through these and to and into the bottom holes of the centre pillar. The through-hole 21 has an inner stop 22 configured to require a lifting of the bar end in the through-hole for withdrawal of a bar from the position between the respective pillar 5-8 and the centre pillar 9 in the exercise mode of the tool. The bars to be arranged between corner pillars and the centre pillar have for this reason no end portion with elliptical cross-section.

[0023] From the above description and Figs. 1-3 it is made abundantly clear that bars can easily be moved to extend between two adjacent corner pillars or a corner pillar and the centre pillar at different heights and safely be held in place in the selected positions without requiring any further securing members. The bars are arranged in different ways depending on what a person wishes to exercise in the tool. At such exercise the person can use the bars as barriers to pass under or over or to climb on or hang in.

[0024] With the exercise tool according to the invention a person can exercise by performing motions in every motion plane, (median plane, dorsal plane, transversal plane) wherein it is especially preferable to combine exercise in several different motion planes, such as motion planes in the form of bending forwards (flexion), bending backwards (extension), bending sideways (lateral flexion) and rotation (to the right or to the left, or outwards and inwards rotation), bringing a body part/extremity outwards or inwards (abduction or adduction) of the body of the person exercising. A few of a large amount of possible training exercises are now to be described with reference to Figs. 4-6, in which a few details of the tool shown in Figs. 1-3 are not shown.

[0025] It is shown in Fig. 4 how a bar 23 can be arranged at a suitable height between two corner pillars 5, 6 to step over, and another bar 24 to bend under. It is shown here how a person exercising moves sideways into said inner room by stepping over the bar 23 and simultaneously bending forwards under the bar 24. By this motion pattern are in addition to hip flexor muscles, such as m.iliopsoas, among others the muscle on the front side of the thigh (m.quadriceps femoris) and also abs and back muscles and other muscles of the torso exercised, since the upper part of the body has to be tensioned during the bending forwards under the bar 24. A bending sideways (lateral flexion) and also a bending forwards (flexion) of the body occur by the motion. The height of the bar 23 is adjusted according to the ability of the person to lift his legs and can be increased as for example a person in rehabilitation training have regained part of his former strength.

[0026] It is shown in Fig. 5 how bars 25, 26 are arranged between the centre pillar 9 and a corner pillar 5 and how a person located in said inner room steps over the lower bar 25 and simultaneously bends the upper part of the body backwards (extension) to pass under the higher bar 26. Partly other muscles are by that exercised than by the motion shown in Fig. 4. By combining motions of types shown and varying these by different positions of bars a very all-round exercise loading the most diverse of muscle groups in the body can be achieved safely and easily controlled.

[0027] Another possible type of exercise in the exercise tool is shown in Fig. 6, in the form of climbing on bars 27-32 arranged at different heights between the centre pillar 9 and corner pillars. By arrangement of a large amount of bars between the different pillars in the exercise tool it is also possible to step and climb around in the exercise tool in the most shifting manner and thereby also move completely or partly hanging in bars. It is also possible to perform training exercises in the form of e.g. chin-ups (pull-ups) by hanging in a bar or with simultaneous partly support from the feet on the ground.

[0028] It is realized that the exercise tool according to the invention advantageously could for example be placed in e.g. a preschool for motion exercise of children, in a gym, in a home for exercise in a home environment, at a physiotherapist for rehabilitation training etc.

[0029] The invention is of course not in any way restricted to the embodiment thereof described above, but many possibilities to modifications thereof will be apparent to a person with ordinary skill in the art without departing from the scope of the invention as defined in the appended claims.

[0030] The number of corner pillars could for example be different than four, such as five or more. Likewise could more than one pillar be arranged in said room, and "centre pillar" is to be interpreted broadly and also includes the case in which the pillar in question is not placed exactly at the center of the inner room, but that it is placed in the inner room at all. Except for the movable bars the tool could have one or more bars fixedly arranged between the pillars.

[0031] The grooves of the first engagement members could be open at the end opposite to what is shown in the figures, i.e. so that the bars instead are introduced in the grooves from inside the inner room and outwards and the bottom of the grooves has at least one portion sloping in the direction of introduction of a bar end therein away from the center of the inner room.
