A VIBRATION SPORTING GOODS

Technical Field

[1] The present invention relates to a vibration sporting goods, the step plate of which vibrates in an up-and-down motion, and more particularly, to a vibration sporting goods having the step plate, with which a user places his/her feet, hands, buttocks, etc thereupon, the user can execute stretching or muscular reinforcement exercises and neuroaugmentation exercises by high-speed vibration in various postures without requiring separate movements. Background Art

[2] In general, a vibration sporting goods comprises a base mounted upon a horizontal surface, a step plate movably mounted upon the base, a driving device arranged on the base to make the step plate elevated up and down, and a control panel installed upon a post standing in rear side of the base. In such case, rotational forces of the driving device are transferred to a driven pulley via a belt connecting the driving pulley with the driven pulley, the rotational forces transferred to the driven pulley are converted to up-down-reciprocating movements through the step plate, such that a user can execute stretching or muscular reinforcement exercises and neuroaugmentation exercises by locating his/her body part upon the step plate vibrating up and down at high-speed according to its axial reciprocating movements.

[3] However, the conventional vibration sporting goods have been suffered from the defects in its endurability, because of its repeatedly laboring step plate without stopping during a short time, and partial loads of the step plate caused by different weights and postures different for each users, thereby it results in making a lot of noises and unstable goods, and therefore the user can not use it easily and effectively.

[4] Additionally, the vibration of the step plate is largely generated only when the user locates his/her both feet widely from the center of the rotational axis, whereas when the user locates his/her both feet narrowly from the center of the rotational axis, the vibration thereof decreases, such that the user can not use it easily, and lots of limitations are also existed in exercise postures.

Technical Problem

[5] An object of the present invention is to provide a structure, which can decrease partial abrasions or operation noises of the goods caused by the each user's partial weighing in use, and improve its endurability, to thereby enable the user to execute exercises more safely. [6] That is, the present invention provides a vibration sporting goods, which comprises a driving motor in which a driving pulley is axially arranged at the center of top surface of a base, which is safely arranged in a horizontal surface; a rotation axle in which a driven pulley connected with the driving pulley via a belt is axially arranged, the rotation axle being arranged in a rotation axle bearing each secured at both sides of the base; a pair of step plate is arranged in a bracket juxtaposed at both sides of the base to thereby pivotally rotate in a step-by-step manner; an elevating means of elevating the step plate up and down by the rotational forces of the rotation axle at the bottom of the step plate and the both ends of the rotation axle is arranged; a casing arranged upon the base and formed of a pair of through-holes thereupon to expose the step plate upward; a horizontal frame in which an operating switch and a grip are installed, the operating switch and the grip being arranged at top end of a standing vertical frame, which is arranged at rear side of the base; and an auxiliary table arranged separately as high as the step plate. Technical Solution

[7] A vibration sporting goods 100 in accordance with preferred embodiments of the present invention, as depicted in Figs. 1 to 6, comprises: a driving motor 3 in which a driving pulley 2 is axially arranged at the center of a base 1 safely arranged in a horizontal surface; a rotation axle 6 in which a driven pulley 5 connected with the driving pulley 2 via a belt 4 is axially arranged to thereby pivotally rotate by a rotation axle bearing 7 each secured at both sides of the base 1 ; an eccentric bearing 8 with phase angle difference of 180 degree is separately set at both ends of the rotation axle 6; each of two separated step plates 11 is secured to a bracket 34 juxtaposed upon both sides of the base 1 to pivotally and independentely rotate in a step-by-step manner; a supporting bearing 10 contacted with the peripheral part of the eccentric bearing 8 at the bottom of the step plate 11 is set apiece; a casing arranged upon the base 1 and formed of a pair of through-holes thereupon to expose the step plate 11 upward; a horizontal frame 17 set on the upper end of a standing-up vertical frame 14 at rear side of the base 1, and on which an operating switch 15 and a grip 16 is set; and an auxiliary table 19 separately arranged as high as the step plate 11.

[8] An elevating means 40 comprises the supporting bearing 10 installed at the lower part from the step plate 11, and the eccentric bearing 8 installed by means of an acephalia bolt 9 at both ends of the rotation axle 6. Thus, when the eccentric bearing 8 is pivotally rotated by the rotation axle 6, the peripheral part thereof orthogonally contacts the peripheral part of the supporting bearing 10, the up-and-down elevation of the supporting bearing 10 by the stroke being as large as the extent of the eccen- trication thereof makes the step plate 11 moving up and down independently. [9] One step plate 11 is separately juxtaposed with the other step plate 11 at regular interval, the rear ends of both the step plates 11 being rotational pivot axes, to thereby form one pair, the each step plates 11 is alternately and pivotally rotated by the eccentric bearing 8 with phase angle difference of 180 degree, the each step plates 11 has a plurality of holes 42 punched at regular interval, and the upper surface of which a rubber pad 35 having raised dots is attached.

[10] Hereinabove, the rear end of the step plate 11 becomes the rotational pivot axis, that is, bolts 37 and 37 coupling with the step plate 11 at rear side thereof, as depicted in Fig. 5, become the rotational pivot axes.

[11] The eccentric bearing 8 is securely installed to the rotation axle 6 by two acephalia bolts 9.

[12] The acephalia bolts 9 are coupled with a welterweight 36 via nuts 21 or coupled with a plurality of nuts 21 to maintain weight balance during the pivotal rotation of the eccentric bearing 8.

[13] The supporting bearing 10 is secured to the bracket 39 set orthogonally with the lower surface of the step plate 11.

[14] A spring hanger 41 for placing a spring 20 between the base 1 and the step plate 11 is united with the step plate 11 to thereby improve the grip of the eccentric bearing 8 and the supporting bearing 10 at both sides of the step plates 11.

[15] The spring 20 caused trace smearing between the peripheral parts of the eccentric bearing 8 and the supporting bearing 10, thereby which makes the supporting bearing 10 rotated by the trace angle during the vibration of the step plate 11 and therefore it diminishes its partial abrasion. In this case, the adequate force for the spring is approximately in the range of 15 kg to 40 kg. That is, when the vibration is made repeatedly because of the orthogonal contact between the eccentric bearing 8 and the supporting bearing 10, the supporting bearing 10 is rotated as little as the trace extent. Such trace rotations arise during the rotation of the eccentric bearing 8, with the peripheral part of the eccentric bearing 8 being chockablock with the peripheral part of the supporting bearing 10 vertically contacted thereto, which is resulted from the deviation of verticality, horizontality, etc. in assembling the goods, and the peculiarity of the structure of the step plate 11 on which the vibration occurs even for ideally assembled goods. And the trace smearing has relation to an elastic force of the spring 20 drawing the step plate 11, the eccentric bearing 8 and the supporting bearing 10 reciprocate within the chockablock parts therebetween, when the elastic force of the spring 20 is large, and the eccentric bearing 8 and the supporting bearing 10 skid, when the elastic force of the spring 20 is small. Therefore, the adequate elastic force is preferred, but whether the elastic force of the spring 20 is large or small, regular doses of smearing might occur, and thereby the objects of the present invention can be ac- complished.

[16] Without the spring 20, the trace smearing is occurred at the contact surface of the eccentric bearing 8 and the supporting bearing 10, the supporting bearing 10 is rotated by the trace extents, the supporting bearing 10 is evenly contacted with the eccentric bearing 8 along the overall side wheels of the supporting bearing 10, thereby preventing the partial abrasions.

[17] However, the spring 20 is installed such that it makes the eccentric bearing 8 and the supporting bearing 10 maintain strong contact condition, thereby preventing the step plate 11 from being bounded excessively, such that it prevents noise, torsion, etc., and prevents the eccentric bearing 8 or the supporting bearing 10 from being run idle so as to be further precisely rotated by little, and therefore improving the decreasing of the partial abrasions.

[18] Of course, the eccentric bearing 8 is also rotated by trace extent of regular angle, by which the abrasions thereof is prevented as that of the supporting bearing 10.

[19] Particularly, preventing the partial abrasions of the eccentric bearing 8 or the supporting bearing 10 by rotating by the trace extent of regular angle caused by the trace smearing is accomplished by the orthogonal contact structure of the eccentric bearing 8 and the supporting bearing 10. That is, the peripheral part of the eccentric bearing 8 or the supporting bearing 10 is a circular arc, when such circular arcs are vertically contacted each other, the contact portions become dots, and such contact portions caused the smearing by the vibrations to make them rotated by the trace angles.

[20] The auxiliary step plate 22 is located upon the upper part of the front casing 13 of the through-holes 12.

[21] A rope 25 and a rope hanger 26 are set upon the front side of the horizontal frame

17 to execute exercises in various postures.

[22] The auxiliary table 19 has a cushion plate 18 covering the upper part of the step plate 11 and detachably mounted thereupon to enable the user to execute exercises in various postures.

[23] A power switch 23 and a vibration control switch 24, which control the power and the intensity of the vibrations, are separately installed at one side of the vertical frame 13 to readily control the goods in exercising in various postures using the auxiliary table 19.

[24] The base 1, the rotational axis bearing 7, the step plate 11, and the bracket 34 are coupled with bolts 37, 37 and nuts 38, 38 to be assembled and deassembled with ease.

[25] The rotation axle 6, as depicted in Fig. 7, is comprised of two pieces, the ends thereof are axially coupled with a coupling 27 connected to both axes of a driving motor 3, such that it is possible to transfer the rotational force of the driving motor 3 directly to the rotation axle 6.

[26] Installation holes 31, as depicted in Fig. 10 and Fig. 11, for installing acupressure pieces 28 able to acupress soles or thenars are formed on one side of the step plate 11.

[27] The acupressure piece 28 is compulsorily fitted to the top end of a detachable part

33 attached to a fixing device 29 by a magnet 32 embedded into the detachable part 33, and which can be configured in various shapes, as depicted in Fig. 12.

[28] Additionally, the vibration sporting goods 100 of this invention, as depicted in Fig.

8 (a), comprises a pair of step plates 11 being situated at both sides of the bracket 34 arranged at the center of the base 1 to independently and pivotally rotate, and the step plates 11 being independently elevated up and down by an elevating means 40 mounted upon the rotation axle 6 and the step plate 11 to which the rotational force of the driving motor 3, being installed at one side of the base 1, is transferred, wherein the elevating means 40 comprises the supporting bearing 10 being installed at the bottom of the step plate 11, and the eccentric bearing 8 being installed at both ends of the rotation axle 6, while the peripheral part of the eccentric bearing 8 contacts orthogonally the peripheral part of the supporting bearing 10 when the eccentric bearing 8 is pivotally rotated by the rotation axle 6, it makes the supporting bearing 10 elevating up and down with the stroke as the extent of eccentricity, such that the step plate 11 elevates up and down.

[29] That is, the above exemplary step plate 11 with two independent pieces are juxtaposed apart at regular interval to become a pair of step plates, the rotation pivot axes of the each step plates 11 are at vis- -vis sides thereof, and the each step plates 11 are alternately and pivotally rotated by the eccentric bearing 8 with the phase angle difference of 180 degree.

[30] Further, the vibration sporting goods 100 of this invention, as depicted in Fig. 8(b), comprises one piece of step plate 11 being secured at the upper side of the bracket 34 mounted on the center of the base 1 to pivotally rotate in a see saw-like manner, the step plate 11 being elevated up and down in a see saw-like manner by the rotation axle 6 to which the rotational force of the driving motor 3 installed at one side of the base 1, and the elevating means 40 installed at the step plate 11, wherein the elevating means 40 comprises the supporting bearing 10 being installed at the bottom of the step plate 11, and the eccentric bearing 8 being installed at both ends of the rotation axle 6, while the peripheral part of the eccentric bearing 8 contacts orthogonally the peripheral part of the supporting bearing 10 when the eccentric bearing 8 is pivotally rotated by the rotation axle 6, it makes the supporting bearing 10 elevating up and down with the stroke as the extent of eccentricity, such that the step plate 11 elevates up and down in a see saw-like manner.

[31] That is, the above exemplary step plate 11 has a rotation pivot axis about the forward and backward direction of the middle part thereof, and the right-and-left step plate 11 is rotated right and left alternately and pivotally in a see saw-like manner by the eccentric bearing 8 with the phase angle difference of 180 degree.

[32] As configured hereinabove, in the vibration sporting goods 100 of this invention, the rotational force generated from the driving motor installed at the middle of the base 1 is transferred to the rotation axle 6 via the belt 4 or the coupling 27, the rotational force transferred to the rotation axle 6, as depicted in Fig. 3, is transferred to the elevation motion of the eccentric bearing 8 with the stroke as the extent of eccentricity, while the peripheral part of the eccentric bearing 8 axially installed to the rotation axle 6 contacts orthogonally the peripheral part of the supporting bearing 10 installed at the bottom of the step plate 11, thereby the supporting bearing 10 forces the two independent step plates 11 to vibrate up and down in a step-by-step manner, and therefore it enables the user to execute vibration exercises.

[33] Most components including the base 1, the rotation axle bearing 7, the step plate

11, and the bracket 34 are coupled and assembled with bolts 37, 37 and nuts 38, 38 , thereby it can be readily assembled by the person unskilled, and therefore if only the bolts 37, 37 and nuts 38, 38 are to be deassembled when any defects exists in the goods, checkup and maintenance can be carried out easily as well as the production efficiency can be largely improved.

[34] Here, when the eccentric bearing 8, which reciprocates the supporting bearing 10 set at the bottom of the step plate 11, is axially installed to the rotation axle 6, the two eccentric bearings 8 are installed to have the phase angle difference of 180 degree, thereby one step plate 11 ascends, while the other step plate 11 descends, and one step plate 11 descends, while the other step plate 11 ascends, and therefore one pair of step plates 11 elevate up and down alternately in the same direction, such that it generates high-speed vibrations.

[35] The step plate 11 is formed by bending a steel plate having a predetermined thickness and punching with a plurality of holes 42 to prevent torsion or deflection or the like resulted from the user's weight during its vibration, such that the weight thereof becomes lighter and additionally its operation noises, produced in no loads and high-speed vibrations that no users stand thereon, decreases, and resonant vibrations can be reduced.

[36] The welterweight 36 of adequate heft is coupled with the acephalia bolts 9, which secures the eccentric bearing 8 to the rotation axle 6 so that the eccentric bearing 8 can be unitarily and pivotally rotated with the rotation axle 6, via nuts 21. Thus, as the eccentric bearing 8 pivotally and unitarily rotates together with the rotation axle 6, it elevates up and down with the stroke as the extent of eccentricity thereof, such that the eccentric bearing 8 rotates smoothly by the welterweight 36 coupled with the acephalia bolts 9, the elevation motions of the supporting bearing 10 contacted orthogonally with the eccentric bearing 8 and the vibration motions of the step plate 11 caused by the supporting bearing 10 can be regularly performed.

[37] Therefore, the operation loads charged on the rotation axle 6, the eccentric bearing

8, and the supporting bearing 10 enabling the step plate 11 to elevate up and down is reduced, thus the operation noises can be remarkably decreased, and therefore the user can execute exercises with ease and safe under gemutlich circumstances.

[38] The spring 20 is installed between the base 1 and the step plate 11, and tension is applied thereto at 15 kg to 40 kg so as to improve the grip of the step plate 11 during the rotation of the eccentric bearing 8, with the peripheral part of the support bearing 10 installed at the lower surface of the step plate 11 contacted with the peripheral part of the eccentric bearing 8, thereby the peripheral part of the eccentric bearing 8 contacts the peripheral part of the supporting bearing 10 during normal operation, such that when the step plate 11 ascends and then descends, trace smearing is induced between the peripheral part of the eccentric bearing 8 and the peripheral part of the supporting bearing 10. Therefore, the supporting bearing 10 rotates by the trace angles through the smearing of the eccentric bearing 8, and thereby the partial abrasion thereof can be prevented.

[39] This is because the smearing between the eccentric bearing 8 and the supporting bearing 10 is generated by the time the inertia force decreases as the power of the spring 20 acts contrary to the direction of the inertia force of the step plate 11, when the step plate 11 ascends.

[40] In such case, because the supporting bearing 10 is orthogonal to the eccentric bearing 8, it appears that there is no relationship with the rotation of the eccentric bearing 8, but the supporting bearing 10 orthogonally contacted by the smearing of the eccentric bearing 8 rotates by the trace angles.

[41] Therefore, as the supporting bearing 10 rotates by the adequate angles at high-speed vibrations generated by the elevation of the step plate 11, the peripheral parts of the eccentric bearing 8 and the supporting bearing 10 are rubbed against each other with balance, thereby diminishing the abrasion generated in the peripheral parts of the eccentric bearing 8 and the supporting bearing 10 extends service lives in use.

[42] Of course, the abrasion of the eccentric bearing 8 rotated by the trace extents is prohibited by the smearing and the rotation of the rotation axle 6.

[43] As such, the user manipulates an operation switch 15 installed upon the top end of the horizontal frame 17 with his/her both feet placing upon the step plate 11, then adjusts the intensity of the vibrations adequate for the user, and subsequently the user grip knobs or ropes arranged in the horizontal frame 17 with his/her both hands, thereby the user can execute stretching exercises, neuroaugmentation exercises, and muscular reinforcement exercises through the high-speed vibrations generated from the step plate 11 without the user's other movements.

[44] In this case, a pair of step plates 11 elevates up and down independently with the phase angle difference of 180 degree in one direction, thereby when the user moves both the feet forward and backward, the user can regulate the vibration intensity transferred to the user's body, and therefore while the user moves both the feet forward and backward in the step plate 11, the user regulates the vibration intensity, such that the user can execute uniform vibration exercises of the user's upper and lower torso.

[45] Even the same vibration, though the user put together or apart both the feet, is transferred to the body, the intensity of the vibrations transferred to the user's upper and lower torso can be diversified according to the area of both the feet different in the structures of pelvis/coxa, and coxa/feet supporting the user's upper torso.

[46] In addition, the vibration sporting goods 100 of this invention comprises the auxiliary step plate 22 being separately set upon the upper part of the front casing 13 of the step plate 11 on which the user's both feet are situated, the auxiliary step plate 22 fasten the user's anterior calcaneus and simultaneously prevent the user's feet from sliding forward, and therefore the user can safely execute exercises.

[47] Furthermore, after placing the user's anterior or posterior calcaneus (heel) upon the auxiliary step plate 22, with the anterior or posterior calcaneus being lifted, the vibration exercises for all the regions of the upper and lower torso can be executed with balance.

[48] In this case, as the user can vary the height of lifting the anterior or posterior calcaneus, the user can simply regulate his/her adequate intensity of the vibrations within the regular range without manipulating the operation switch 15 installed in the horizontal frame 17, and therefore the user can execute exercises according to the intensity adequate for the user.

[49] Moreover, in the vibration sporting goods 100 of this invention, as depicted in Fig.

9(a), after placing the cushion plate 18, which is detachable on the auxiliary table 19, upon the step plate 11 using the auxiliary table 19 separately prepared, and placing the auxiliary table 19 and the auxiliary table at the side of the vibration sporting goods 100 side by side, the user can execute vibration exercises with all his/her body lying down thereupon.

[50] As depicted in Figs. 9(b) and 9(c), after placing the auxiliary table 19 at the front side of the vibration sporting goods 100, the user in sitting posture can extend his/her both hands aback to place them upon the cushion plate 18, thereby the user can execute vibration exercises mainly for the upper torso.

[51] After lying down upon the auxiliary table 19 and the cushion plate 18 in a lengthwise direction, placing buttocks upon the cushion plate 18, and superimposing both the feet upon the ropes 25, the user can execute vibration exercises mainly for the lower torso. Further, the user can execute vibration exercises in various postures using the auxiliary table 19, the cushion plate 18, and the rope 25, but it is not depicted in the figure.

[52] In this case, the power switch 23 and the vibration control switch 24 can be separately arranged at one side of one pair of the vertical frame 14 to control the power and the vibration intensity. Therefore, the user can control the operation of the vibration sporting goods 100 easily even in his/her lying-down posture.

[53] Additionally, in the vibration sporting goods 100 of this invention, the installation holes 31 to which the fixing device 29, for installing the acupressure piece 28 attached by the magnet 32 in the detachable part 33, being installed are formed upon the surface of the step plate 11. The fixing device 29 coupled with the installation hole 31 via bolt 30 is secured to the step plate 11. Then, after attaching the detachable part 33, upon which the acupressure piece 28 being installed, on the installation holes 31 by the magnetic force, operating the vibration sporting goods 100, and placing hands, soles, or the like on the acupressure pieces 28, thereby it enables to partially acupress the hands, the soles, or the like through the vibrations of the step plate 11.

[54] Here, the acupressure piece 28, as depicted in Figs. 12(a) to 12(c), can be formed with various shapes, can be utilized by simply inserting into the detachable part 33, and can be readily installed into the fixing device 29 because of its embedded magnet 32 in the lower part thereof.

Advantageous Effects

[55] As described above, the present invention generates high-speed vibrations as a pair of step plates 11 pivotally rotates in a step-by-step manner, the vibration is transferred to the posterior calcaneus to which the weight of the user being concentrated, such that in addition to largely increase the efficiency of the vibration exercises, the user can regulate the vibration intensity during the operation of the step plate 11 forward and backward, and the user can readily execute vibration exercises as the constant vibration takes place up and down without limitations to the width between both the feet. The elevation means 40 of the step plate 11 comprises the eccentric bearing 8 and the supporting bearing 10, in which the peripheral parts thereof being contacted orthogonally, thereby it improves the endurability of the goods, and even when the torsion and the eccentric weight are applied to the step plate 11, it can smoothly generate up-down vibrations. The auxiliary table 19 is separately arranged, thereby the vibration exercises and the massages can be performed in various exercise postures such as the user's sitting or lying posture. Most components are assembled with the bolts 37, 27' and nuts 38, 38', thereby the productivity can be magnified, and even when the assembling order between the components is reversed, it can be assembled easily, and therefore the check-up and the maintenance can be effectively performed.
