FITNESS STRUCTURE
A fitness structure includes a first standing member including a plurality of first guiding grooves located at different heights, a second standing member facing the first standing member and including a plurality of second guiding grooves respectively facing the plurality of first guiding grooves, and a catcher bar including a barbell support part extending in a first direction and an inserting and withdrawing part protruding from both end portions of the barbell support part, and supported by the first standing member and the second standing member as the inserting and withdrawing part is inserted into one of the plurality of first guiding grooves and one of the plurality of second guiding grooves facing each other, in which each of the plurality of first guiding grooves and the second guiding groove includes a horizontal groove guiding the inserting and withdrawing part in a second direction perpendicular to the first direction from an opening that is an entrance into which the inserting and withdrawing part is inserted, and a vertical groove connected from the horizontal groove and guiding the inserting and withdrawing part toward an accommodation part, and the inserting and withdrawing part has a vertical cross-section at least partially extending in a lengthwise direction of the vertical groove.
The present invention relates to a fitness structure, and more particularly, to a fitness structure for weight training.
BACKGROUND ARTRecently, as social interest about beauty and health has increased, the number of people that keeps weight training to improve muscle strength and build a balanced body has increased. Weight training improves physical strength by training muscle strength using an object having a weight such as a barbell or a dumbbell. Exercises for weight training include bench press, squats, deadlifts, etc. A fitness club has various types of exercise equipment to do such exercises.
To do a squat motion, which is a weight training exercise, basically, a barbell including a metal bar and disc weights provided at both ends of the metal bar is needed. Unlike this, according to technologies disclosed in Korean Patent Publication No. 10-2011-0122618 laid open on Nov. 10, 2011 and Korean Patent No. 10-0657716 published on Dec. 14, 2006, the squat motion may be done using fitness equipment including a combination of weights and pulleys instead of a barbell. However, using the fitness equipment having complex functions is inconvenient and muscles may not be uniformly trained because balance muscles and accessory muscles cannot be trained together unlike free weights.
Alternatively, when a barbell is used to perform a squat motion, a person working out repeats motions of standing with the barbell on one's shoulder, lowering one's torso into a squat, and then, raising the torso back to the upright position. In doing so, since the person working out who performs the squat motion needs to lift the barbell that weighs equally or greater than the person working out, control of the barbell in the repetition of the motion may be lost, which may lead to a safety accident. To prevent the safety accident, some fitness structures are provided with a catcher bar for catching a barbell at an appropriate height so that a person working out may not be hurt due to the weight of the barbell that is not controlled. However, when persons having different figures use the same fitness structure, the position of a catcher bar needs to be changed according to the figure of each person. For a conventional catcher bar, a person working out may be inconvenienced because changing the position of the catcher bar is not easy.
Alternatively, when a barbell is used to perform the squat motion, the motions of standing with the barbell on one's shoulder, lowering one's torso down into a squat, and then, raising the torso back to the upright position are repeated. In doing so, since the person working out, who performs the squat motion, needs to lift the barbell, which weighs equally or greater than the person working out, a support frame to place the barbell thereon is needed in order to facilitate the squat motion. In this connection, Korean Patent No. 10-0657716, published on Dec. 14, 2006, discloses a weight removing apparatus which enables a barbell that is appropriately placed for a bench press motion, not a squat motion.
However, according to a prior art, no fitness equipment has been proposed which facilitates placing a barbell on a support according to one's height when persons having different heights perform a squat motion by using a single barbell support frame. Also, when a barbell is placed on a support, a finger of a person working out may be hurt if it is squeezed between the barbell and fitness equipment.
DETAILED DESCRIPTION OF THE INVENTION Technical ProblemThe present inventive concept provides a fitness structure having a catcher bar that may be easily set to an appropriate height according to a figure of a user who performs a weight training motion such as a squat.
Also, the present inventive concept provides a fitness structure which may facilitate placing a barbell on a catcher bar regardless of the height of a user who performs a squat motion.
Technical SolutionAccording to an aspect of the present inventive concept, there is provided a fitness structure which includes a first standing member including a plurality of first guiding grooves located at different heights, a second standing member facing the first standing member and including a plurality of second guiding grooves respectively facing the plurality of first guiding grooves, and a catcher bar including a barbell support part extending in a first direction and an inserting and withdrawing part protruding from both end portions of the barbell support part, and supported by the first standing member and the second standing member as the inserting and withdrawing part is inserted into one of the plurality of first guiding grooves and one of the plurality of second guiding grooves facing each other, in which each of the plurality of first guiding grooves and the second guiding groove includes a horizontal groove guiding the inserting and withdrawing part in a second direction perpendicular to the first direction from an opening that is an entrance into which the inserting and withdrawing part is inserted, and a vertical groove connected from the horizontal groove and guiding the inserting and withdrawing part toward an accommodation part, and the inserting and withdrawing part has a vertical cross-section at least partially extending in a lengthwise direction of the vertical groove.
The inserting and withdrawing part may be supported by fixed walls located at both sides of the vertical groove in the accommodation part.
One inserting and withdrawing part may be formed at each end portion of the barbell support part.
A vertical cross-section of the inserting and withdrawing part or the barbell support part may have a polygonal shape.
The barbell support part may have a flat upper surface.
In the opening of each of the plurality of first guiding grooves or each of the plurality of second guiding grooves, a vertical width of the opening at a side of the entrance may be greater than a vertical width of the opening at a side of the horizontal groove.
According to an aspect of the present inventive concept, there is provided a fitness structure for accommodating a barbell which includes a pair of standing structures comprising a front surface in which a plurality of first insertion holes, each having a first width, are formed, a rear surface located corresponding to the front surface and in which a plurality of second insertion holes, each having a second width, are respectively formed corresponding to the plurality of first insertion holes, and first and second side surfaces respectively connecting the front and rear surfaces, an insertion pin comprising a protruding part having a width that is smaller than the first width and partially passes through each of the plurality of first insertion holes and an insertion part located at a tip end of the protruding part, having a width that is smaller than the second width, and partially passing through each of the plurality of second insertion holes to protrude from the rear surface, and a support structure connecting the standing structures to have the second side surfaces of the pair of standing structures face to each other, in which the first width is greater than the second width and a width of the protruding part is greater than the second width.
Each of the standing structures may include an upper standing structure comprising the front surface, the first side surface, the second side surface, and the rear surface, and a lower standing structure connecting the support structure and each of the standing structures, in which a lengthwise direction of the upper standing structure is inclined with respect to a direction perpendicular to ground.
When being inserted into the standing structure, the insertion pin may be disposed such that a lengthwise direction of the insertion pin is substantially perpendicular to the front surface.
A shape of the first insertion hole and a shape of a cross-section of the protruding part, or a shape of the second insertion hole and a shape of a cross-section of the insertion part, may be congruous with each other, and the shape is any one of a polygon and a circle.
The fitness structure may further include a protection part located protruding from the front surface to prevent a barbell from contacting the front surface.
The protection part may be arranged in a lengthwise direction of the upper standing structure on the first side surface.
Advantageous EffectsIn the fitness structure according to the present exemplary embodiments, even when users use the same fitness structure, the position of a catcher bar may be easily set to an appropriate height according to the figure of each person. Also, since guiding grooves of a standing member include a horizontal groove and a vertical groove extending toward the horizontal groove, and an inserting and withdrawing part of the catcher bar inserted in the guiding groove is supported by a fixed wall disposed at both sides of the vertical groove, the catcher bar may be prevented from being shaken or rotated by an external force.
Furthermore, in an opening part of the guiding groove, because a vertical width of the opening at a side of an entrance is wider than a vertical width of the opening at a side facing the inside of the guiding groove, the catcher bar may be easily inserted into each guiding groove.
Also, in the fitness structure according to the present exemplary embodiments, for a standing structure including a plurality of insertion holes, by inserting an insertion pin into the insertion hole located at an appropriate height, even when users use the same fitness structure, each user may easily place a barbell suitable for one's height.
Also, as a protection part protruding from a front surface of the standing structure, the standing structure may be protected from a shock applied when the barbell is placed on a catcher bar and simultaneously a finger of a user who places the barbell on a catcher bar may be prevented from being hurt
In detail, when placing a barbell on a catcher bar after finishing an exercise such as a squat, a user may have the barbell closely contact a portion of the standing structure at a higher position than a portion where the insertion pin is located and then slide the barbell down along the standing structure to a portion where the insertion pin is located. In doing so, as the barbell is guided toward the insertion pin without having to directly contact the front surface of the standing structure by the protection part, the barbell may be easily placed on the fitness structure and simultaneously the standing structure may be protected.
Exemplary embodiments of the present inventive concept are described in detail with reference to the accompanying drawings. However, the present inventive concept is not limited thereto and it will be understood that various changes in form and details may be made therein without departing from the spirit and scope of the following claims. That is, descriptions on particular structures or functions may be presented merely for explaining exemplary embodiments of the present inventive concept.
Terms such as “first” and “second” are used herein merely to describe a variety of constituent elements, but the constituent elements are not limited by the terms. Such terms are used only for the purpose of distinguishing one constituent element from another constituent element. For example, without departing from the right scope of the present inventive concept, a first constituent element may be referred to as a second constituent element, and vice versa.

The catcher bar 310 may include a barbell support part 315 extending in a first direction D1 and a pair of inserting and withdrawing parts 317a and 317b formed respectively at both end portions of the barbell support part 315. The upper surface 315_1 of the barbell support part 315 may be formed to be substantially flat to increase a friction area to the barbell. Although not illustrated, a rubber pad, for example, may be attached on the upper surface 315_1 of the barbell support part 315. The catcher bar 310 is installed as the inserting and withdrawing parts 317a and 317b are respectively inserted into the first and second guiding grooves. In particular, the catcher bar 310 is installed such that the first direction D1 in which the catcher bar 310 extends is perpendicular to a third direction D3 in which the first and second standing members 210 and 280 extend. The barbell support part 315 and the inserting and withdrawing parts 317a and 317b are described below in detail with reference to
Referring back to
The leg parts 410 may support a load applied to the support structure 400 by distributing the load. For example, when the support structure 400 has a shape of a rectangle with one open side, the four leg parts 410 including angled portions of the shape of a rectangle with one open side may support the support structure 400.
Referring to
The horizontal groove HG extends in a second direction D2, which is perpendicular to the first direction D1 that is a direction in which the barbell support part 315 extends. One end of the horizontal groove HG is connected to the opening OP. The vertical groove VG is connected to the accommodation part AP from the other end of the horizontal groove HG. Fixed walls W1 and W2 extending in the third direction D3, in which the first standing members 210 extend, are located at both sides of the vertical groove VG. In the present exemplary embodiment, the guiding groove GG may have an L-shape including the horizontal groove HG and the vertical groove VG.
The inserting and withdrawing parts 317a and 317b of the catcher bar 310 may be a first inserting and withdrawing part 317a formed on end of the barbell support part 315 to be inserted into one of the first standing members 210, and a second inserting and withdrawing part 317b formed at the other end of the barbell support part 315 to be inserted in one of the second standing members 280. As described later, in the first and second inserting and withdrawing parts 317a and 317b accommodated in the accommodation part AP, side surfaces 317a_1 and 317a_2 contact the fixed walls W1 and W2 disposed at both sides of the vertical groove VG and are fixed thereon. Accordingly, rotation or shaking of the catcher bar 310 in the guiding groove GG while the catcher bar 310 is installed in the guiding groove GG may be reduced. For example, vertical cross-sections of the first and second inserting and withdrawing parts 317a and 317b, in other words, cross-sections cut in the third direction D3 may have a shape that at least partially extends in the third direction D3 that is a length direction of the vertical groove VG. In the present exemplary embodiment, the first inserting and withdrawing part 317a may have the two side surfaces 317a_1 and 317a_2 contacting the fixed walls W1 and W2 in the third direction D3, and a vertical cross-section having a rectangular shape. Also, a vertical cross-section of the barbell support part 315 may have a rectangular shape having an area larger than that of each of the first and second inserting and withdrawing parts 317a and 317b.

Although
As such, the first standing members 210 of the fitness structure 100 according to the present exemplary embodiment may include the guiding groove GG having an L-shape including the flat accommodation part AP, and the catcher bar 310 inserted into the guiding groove GG may include the inserting and withdrawing parts 317a and 317b each having a vertical cross-section having a rectangular shape. However, the shapes are exemplary, and the catcher bar 310 is fixed in the guiding groove GG by the inserting and withdrawing parts 317a and 317b each having a shape at least partially extending in a direction along the length of the vertical groove VG and the fixed walls W1 and W2 arranged at both sides of the vertical groove VG to support the inserting and withdrawing parts 317a and 317b, thereby stably supporting the barbell.
Also, since the first and second standing members 210 and 280 include a plurality of guiding grooves GG having different heights, even when users use the same fitness structure, the catcher bar 310 may be easily installed at a height suitable for a figure of each user.

Also, the catcher bars 320, 330, and 340 may include barbell support parts 325, 335, and 345 having substantially flat upper surfaces 325_1, 335_1, and 345_1. Unlike the flat upper surfaces 325_1, 335_1, and 345_1 of the barbell support parts 325, 335, and 345, the lower surface or side surface of a barbell support part may not be flat. For example, the lower surface of the barbell support part 345 may have a round shape. However, this is exemplary and the side surface or lower surface of the barbell support part may have various shapes.
Referring to
As described above, in the fitness structure according to the present exemplary embodiments, since each standing member includes a plurality of guiding grooves having different heights, even when users use the same fitness structure, the position of the catcher bar may be easily set to a height appropriate to a figure of each user. Also, each of the guiding grooves of the standing member includes a horizontal groove having an opening and a vertical groove connected to the horizontal groove. Since the inserting and withdrawing part of the catcher bar inserted into the guiding groove is supported by the fixed walls located at both sides of the vertical groove, the catcher bar may be prevented from being shaken or rotated by an external force.
Furthermore, since the opening of the guiding groove is formed such that a vertical width of the opening at a side of an entrance is wider than a vertical width of the opening at a side close to the inside of the guiding groove, the catcher bar may be easily inserted into the guiding groove.
MODE OF THE INVENTIONReferring to
In the present exemplary embodiment, the standing structure 1200 and the support structure 1500 may be formed of a solid metal material, for example, iron (Fe) or an iron alloy.
The upper standing structure 1210 may include a front surface 1211a, a first side surface 1211b, a second side surface 1211c, and a rear surface 1211d. For example, the upper standing structure 1210 may be formed of a hollow steel frame that is formed as four steel panels extending long in one direction are coupled.
A plurality of first insertion holes 1215 are formed in the front surface 1211a.
A protection part 1213 is attached on the first side surface 1211b. In some embodiments, the protection part 1213 may contain the same material as that of the upper standing structure 1210. Alternatively, the protection part 1213 may contain a different material from that of the upper standing structure 1210. For example, the protection part 1213 may contain aluminum or an aluminum alloy.
The second side surface 1211c is opposite to the first side surface 1211b, and the rear surface 1211d is opposite to the front surface 1211a. The coupling relation between the upper standing structure 1210 and the insertion pin 1300 is described below in detail with reference to
One end of the lower standing structure 1250 is connected to the upper standing structure 1210 and the other end thereof is connected to the support structure 1500. The lower standing structure 1250 may be connected to the support structure 1500 such that a lengthwise direction of the lower standing structure 1250 is substantially perpendicular to the ground. For example, the lower standing structure 1250 may be connected to the support structure 1500 to stand up to a predetermined height with respect to the support structure 1500. In some embodiments, the lower standing structure 1250 and the support structure 1500 may be integrally formed. The lower standing structure 1250 is connected to the upper standing structure 1210 forming a predetermined angle ANG2 therebetween. For example, the upper standing structure 1210 may be connected to the lower standing structure 1250 to be inclined at an angle with respect to a direction in which the lower standing structure 1250 stands up. Accordingly, the upper standing structure 1210 may be arranged such that the lengthwise direction of the upper standing structure 1210 is inclined with respect to a direction perpendicular to the ground. Also, in some embodiments, the upper standing structure 1210 and the lower standing structure 1250 may be integrally formed. In the present exemplary embodiment, although the lower standing structure 1250 is illustrated as having four surfaces similar to the upper standing structure 1210, this is exemplary and the shape of the lower standing structure 1250 is not limited thereto. For example, the lower standing structure 1250 may have a cylindrical shape or a polygonal column shape.
The insertion pin 1300 is inserted into any one of the first insertion holes 1215 in each upper standing structure 1210. In some embodiments, a plurality of the insertion pins 1300 may be inserted in the upper standing structure 1210. In general, the insertion pin 1300 may be located at the same height at each of a pair of the upper standing structures 1210. The insertion pin 1300 may contain the same material as that of the standing structure 1200, or a light metal material, for example, aluminum A1 or an aluminum alloy.
The standing support structure 1520 may be connected to one end of the upper standing structure 1210. For example, the standing support structure 1520 may be connected to the rear surface 1211d of one end of the upper standing structure 1210. The standing support structure 1520 supports the upper standing structure 1210, and thus an external shock applied to the front surface 1211a of the upper standing structure 1210 may be absorbed. Also, the standing support structure 1520 is connected to the upholding structure 1510. In some embodiments, the standing support structure 1520 and the upholding structure 1510 may be integrally formed.
The upholding structure 1510 has a bent shape when viewed from above, and supports the standing structures 1200. For example, the upholding structure 1510, when viewed from above, may have a shape of a rectangle with one open side. In this case, the upholding structure 1510 has an open side through which a user of the fitness structure 1100 passes. The upholding structure 1510 may support two standing structures 1200 such that, when the user is located inside the shape of a rectangle with one open side, each of the standing structure 1200 is located at either side surface. In the present exemplary embodiment, the two upper standing structures 1210 are arranged such that the second side surfaces 1211c face each other. Also, in the present exemplary embodiment, the protection part 1213 included in each upper standing structure 1210 is arranged to face the outside of the shape of a rectangle with one open side. In the following description, the inside of the shape of a rectangle with one open side that the second side surfaces 1211c face is referred to as an interior, and the outside of the shape of a rectangle with one open side that the first side surfaces 1211b or the protection parts 1213 face is referred to as an exterior. Also, an open direction of the shape of a rectangle with one open side is referred to as a front side, and a closed direction of the shape of a rectangle with one open side is referred to as a rear side. However, this is merely for convenience of explanation and the interior and the exterior, or the front side and the rear side, may be differently defined according to the shape of the upholding structure 1510.
The upholding structure 1510 may include the leg parts 1515 that separate the standing structure 1200 from the ground by a predetermined height. In this case, the leg part 1515 may support a weight applied to the upholding structure 1510 by distributing the load. For example, when the upholding structure 1510 has the shape of a rectangle with one open side, the four leg parts 1515 including angled portions of the shape of a rectangle with one open side may support the upholding structure 1510.
Referring to
The front surface 1211a may include the first insertion holes 1215 arranged at different heights. Each of the first insertion holes 1215 may be a circular through-hole having a first width D1. The first widths D1 of the first insertion holes 1215 may be substantially the same in each upper standing structure 1210.
The first side surface 1211b may connect the front surface 1211a and the rear surface 1211d. The protection part 1213 that extends long in the lengthwise direction of the upper standing structure 1210 is arranged on the first side surface 1211b. The protection part 1213 may have a thin panel shape having a predetermined width. However, since the thickness of the protection part 1213 is smaller than the width of a surface of each upper standing structure 1210, for convenience of explanation, the thickness of the protection part 1213 is not separately illustrated in the accompanying drawings.
The protection part 1213 is arranged on the first side surface 1211b to protrude from the front surface 1211a by a predetermined width H. Accordingly, when viewed from the inside of the fitness structure 1100, a part of the protection part 1213 may be exposed above the front surface 1211a. As such, as the protection part 1213 protrudes from the front surface 1211a, the front surface 1211a may be protected from a bar of the barbell approaching the front surface 1211a so that the bar of the barbell may not directly contact the front surface 1211a. Also, the protection part 1213 may prevent a finger of the user gripping the barbell, for example, a little finger part, from being hurt by being caught between the bar and the front surface 1211a.
In some embodiments, as the protection part 1213 is arranged to extend in the lengthwise direction of the upper standing structure 1210, the protection part 1213 may constantly maintain the width H protruding from the front surface 1211a in the lengthwise direction of the upper standing structure 1210. Accordingly, when the barbell approaches the front surface 1211a from a position higher than the insertion pin 1300, the protection part 1213 may guide the barbell to the height of the insertion pin 1300 that is inserted at a height lower than that of the barbell. Accordingly, when the insertion pin 1300 is inserted at an appropriate height, the barbell may be easily placed regardless of the height of the user.
However, the protection part according to the present exemplary embodiment is not limited to the shape of the protection part 1213 that is attached on first side surface 1211b according to the above-described exemplary embodiment, and may have various shapes which protrude from the front surface and prevents the barbell from directly contacting the front surface.
The second side surface 1211c connects the front surface 1211a and the rear surface 1211d, and is opposite to the first side surface 1211b.
The rear surface 1211d may include a plurality of second insertion holes 1217 arranged at different heights. Each of the second insertion holes 1217 may be a circular through-hole having a second width D2. The second width D2 of each of the second insertion holes 1217 is smaller than the first width D1 of each of the first insertion holes 1215. Also, the second insertion holes 1217 respectively correspond to the first insertion holes 1215 arranged in the front surface 1211a.
Referring to
The first diameter W1 of the protruding part 1320 and the second diameter W2 of the insertion part 1310 are smaller than the first width D1 and the second width D2, respectively. Also, a boundary part 1315 of the protruding part 1320 and the insertion part 1310 may include a surface that is substantially perpendicular to the lengthwise direction of the insertion pin 1300. The protruding part 1320 of the insertion pin 1300 may extend longer than the insertion part 1310.

Although
As described above, in the fitness structure according to the above-described exemplary embodiments, as the insertion pin is inserted in the insertion hole located at an appropriate height with respect to the standing structure including the insertion holes, even when users use the same fitness structure, the barbell may be easily placed suitable for the height of each user.
Also, since the protection part that protrudes above the front surface is included in the side surface of the standing structure, the protection part may protect the standing structure from the shock applied when the barbell is placed and simultaneously prevent injury to a finger of the user who places the barbell.
Furthermore, when the insertion pin is inserted at a position lower than the height of the user, as the barbell is guided along the side surface of the protection part to a portion where the insertion pin and the standing structure are coupled, the barbell may be easily placed on the fitness structure.
INDUSTRIAL APPLICABILITYThe present inventive concept may be applied to all fitness structures used for weight training.
