Hereinafter, a detailed description of the twist step movement exercise device of the present invention will be disclosed along with examples of the attached drawings. In addition to the configuration described, there are additions such as elastic force adding devices that maintain the level and apply resistance to movement, rotational connection devices such as hinge joints/pivot joints, devices that count and monitor the number of movements, devices that limit the range of rolling motion, etc. Regarding the actual components, etc., the specific method may be cited as a known method.

In addition to the dictionary meaning, the terms used can be converted if they make sense. For example, terms such as forming, extending, connecting, combining, binding, fixing, assembling, providing, installing, and arranging, which refer to forming a composition, are interchangeable. Extension or connection refers to connecting by protruding from one component, or by taking separate components and joining them by known methods such as welding, riveting, or bracketing. Spaced arrangement refers to the position where a plurality of components are placed at a distance from each other. '/' used in the description is intended to indicate optional meaning, list, or indicate the same category.

Length members refer to members such as circular or square rods (pipes), rectangular plates, etc. made of strong metal, synthetic resin, wood, etc.

Functional expressions such as movement, movement, and operation, which represent actions, can also be used interchangeably as long as the meaning remains the same. Expressions of direction such as front, back, left, right, etc. are relative to each other and can be used interchangeably. For example, front can be converted to rear, and rear can be converted to front.

Terms such as front-to-back, left-right, up-down, vertical, and horizontal do not require mathematical precision, and include tilted, tilted, or crooked states depending on the needs of product manufacturing ease or market demand. The horizontal plane (xy) refers to a horizontal space consisting of planes in the front-to-back direction (y) and the left-right direction (x). The vertical plane (xz)/(yz) refers to a vertical space consisting of planes in the left/right direction (x)/forward/backward direction (y) and up/down direction (z).

The up/down direction (z) does not necessarily have to be up or down on an exact vertical line and therefore may have different positions on the horizontal plane (xy). This is the same concept for the front-to-back direction (y) or left-right direction (x).

The horizontal axis rotation (p20rotate) rotates forward and backward repeatedly around the horizontal axis part (p20) arranged in the forward and backward directions (y), so that the cloud part 200 rotates clockwise/counterclockwise on the vertical plane (xz) (xz). says that That is, the cloud part 200 rotates using the horizontal axis part p20 as the rotation axis.

Vertical axis rotation (p10rotate) occurs when the cloud part 200 rolls back and forth on the floor left and right according to the horizontal axis rotation (p20rotate), and the cloud part 200/cloud member 210 moves in the left and right direction (x). It refers to repeating reciprocating movements in the left and right directions (x) along an imaginary arc (on the arc) on the horizontal plane (xy) centered on the vertical axis portion (p10). In other words, the horizontal axis rotation (p20rotate) is converted to the vertical axis rotation (p10rotate), and the rolling part 200 moves left and right using the vertical axis part (p10) as the rotation axis, which causes a twisting motion by left and right arc motion. .

A rotational connection (rotational connection) refers to a connection between two components that can be rotated, twisted, or bent. For the rotation connection, a pivot joint about a center point that rotates as shown in FIG. 7 (a), a hinge joint whose angle changes like the hinge in the example of FIG. 7 (b), etc. are used. The distinction between pivot joint and hinge joint can be used interchangeably depending on the perspective or arrangement status of the two connected comparison objects and components. The rotational connection can be achieved through a pin-shaped shaft member (pn), or by directly fitting or installing the two components.

The present invention is an exercise device having a vertical axis portion (p10) that guides vertical axis rotation (p10rotate) and a horizontal shaft portion (p20) that guides horizontal axis rotation (p20rotate), and is spaced apart in the forward/backward direction (y) and placed on the floor. A fixed part 100 and a rolling part 200, a pair of stepping parts 300 arranged to place the left and right feet spaced apart in the left and right direction (x) between the fixed part 100 and the rolling part 200, It includes a fixing part 100, a binding part 400 arranged to couple the rolling part 200 and the tread part 300 to each other.

The combined fixing part 100 and the binding part 400 respond by adding to or subtracting from the height of the cloud part 200. Accordingly, when the vertical height (length) of the binding portion 400 in the vertical direction (z) is formed to be small/large, on the contrary, the vertical height (length) of the fixing portion 100 in the vertical direction (z) is formed to be large/small.

That is, the auxiliary horizontal maintenance part 320'/auxiliary horizontal maintenance upper and lower extension member 321' is disposed spaced apart from the horizontal maintenance unit 320/horizontal maintenance upper and lower extension member 321 on the horizontal plane (xy). The auxiliary horizontal maintenance upper and lower extension members 321' extend in the vertical direction (z) of the stepping member 310 and are connected to the body/rolling part 200 through the auxiliary horizontal maintenance shaft part (p30').

The horizontal maintaining link member 322 is provided with a horizontal maintaining shaft member (p51) at each left and right end of the body, and a horizontal maintaining shaft for forming a horizontal maintaining shaft portion (p40) at the center between the left and right horizontal maintaining shaft members (p51). It has a member (p42).

In the example of Figure 7 (c), the horizontal maintaining link member 322 may be cut in the middle, that is, placed one on the left and right (322'L, 322'R), and in this case, conceptually, the whole is formed as one. It is viewed as a horizontal maintenance link member (322).

The horizontal maintaining upper and lower extension member 321 has a horizontal maintaining shaft member (p52) at its end/body, and the horizontal maintaining shaft member (p52) and the horizontal maintaining shaft member (p51) of the horizontal maintaining link member 322 are rotationally connected. Together, they form a horizontal maintaining shaft portion (p50).

As shown in the example of FIG. 2, the horizontal maintenance upper and lower extension members 321 connected to the front and bottom of the stepping member 310 are rotationally connected to the left and right ends of the extension member 220/left and right extension members 222, respectively, through the horizontal maintenance shaft portion (p30). Or, as in the example of FIG. 11, the horizontal maintaining shaft portion (p30) directly formed (attached and coupled) to the front bottom of the stepping member 310 is connected to the front and rear extension members 221 and side front and rear extension members 221b on the left and right.

All of these rotational connections are linked together and perform the function of four-bar links (operating in the form of a parallelogram).

Accordingly, as shown in the example of FIG. 9, even if the rolling part 200 is tilted to the left and right due to the horizontal axis rotation (p20rotate), the fixing part 100 and the binding part 400 coupled thereto do not tilt sideways but always stand upright, Since the horizontal shaft portion (p20) and the horizontal maintaining shaft portion (p40) are always placed on a vertical line, the horizontal maintaining upper and lower extension members 321 are also always placed on a vertical line, so that the stepping member 310 can always remain horizontal.

In the case where the side front/rear extension member 221b is provided as shown in the examples of Figures 4, 5, 10, and 11, the side front/rear extension member 221b is provided as the horizontal maintenance shaft member (p31) of the rolling part 200. , Here, the horizontal maintaining shaft member (p32) of the stepping portion (300)/stepping member (310) is rotatably connected to form the horizontal maintaining shaft portion (p30).

Here, a horizontal maintenance shaft member (p32) can be provided that is coupled along the length of the festival member (32b) to form a more stable rotational connection. At least one axial extension member 32c is provided to support (support) the stepping member 310. At this time, the axial upper extension member 32c is similar to the auxiliary horizontal maintenance upper and lower extension member 321'.

A horizontal maintaining shaft member (p52) is provided at the lower end of the shaft extension member (32a), and a hinge joint is formed with the horizontal maintaining shaft member (p51) at the end of the horizontal maintaining link member 322 to form a horizontal maintaining shaft portion ( p50).

As shown in the example of Figure 5 (b), the configuration of the extension member 220 does not include the left and right extension members 222 and consists only of the front and rear extension members 221, 221a and 221b, so that the side front and rear extension members 221b are positioned along the horizontal maintaining axis. It can be provided directly as a member (p31). In this case, the front end of the side front/back extension member (221b) and the rear end of the extension member (32b) may be rotationally connected through a pivot joint, see Figure 4 (b). The horizontal maintenance upper and lower extension member 321 illustrated in FIG. 5 (b) is of the form illustrated in FIG. 2.

The binding portion 400 is,

It has a length or gap in the vertical direction (z), and the lower part/body of the binding part 400 is provided with a vertical axis member (p12), and the vertical axis member (p12) of the binding part 400 is the vertical axis of the fixing part 100. It is rotationally connected to the member p11 to form a vertical axis portion p10, and the rotational connection here may be a pivot joint.

The upper/body of the binding unit 400 is provided with a horizontal axis member (p21), and the horizontal axis member (p21) of the binding unit 400 and the horizontal axis member (p22) of the rolling unit 200 are rotationally connected to form a horizontal shaft together. (p20) is configured, and the rotation connection here may be a pivot joint.

The body/upper portion of the binding unit 400 is provided with a horizontal maintaining shaft member (p41), and the horizontal maintaining shaft member (p41) of the binding unit 400 rotates on the horizontal maintaining shaft member (p42) of the stepping unit 300. They are connected together to form a horizontal maintaining shaft portion (p40). The horizontal shaft member (p21) and the horizontal maintaining shaft member (p41) are arranged to be spaced apart in the vertical direction (z).

The fixing part 100, the rolling part 200, and the treading part 300 are assembled and connected to each other through the binding part 400, and this connection is formed by the vertical axis part (p10), the horizontal axis part (p20), and the horizontal maintaining axis part (p40). ) and the left and right pair of horizontal maintaining shaft portions (p30) and the left and right pair of horizontal maintaining shaft portions (p50) are formed through rotational connection. And in the binding portion 400, which is supported by the fixing portion 100 and always maintained in an upright state, the two horizontal shaft portions (p20) and the horizontal maintaining shaft portion (p40), which are spaced apart in the vertical direction (z), are always positioned up and down. The direction (z) remains vertically arranged.

The binding portion 400 takes the form of a length member having a vertical length, and has a vertical axis member (p12) disposed below in the vertical direction (z) at the bottom, and disposed in the front-back direction (x) at the top. It is provided with a horizontal axis member (p21). The combined height of the fixing part 100 and the binding part 400 is planned to correspond to or add to or subtract from the overall height of the rolling part 200/rolling member 210. For example, as shown in the examples of Figures 6 (a) and 6 (b), if the vertical height of the fixing part 100 is small or large, the vertical height of the binding part 400 may be made large or small.

Meanwhile, as shown in the example of Figure 6 (c), even if the horizontal maintaining shaft member (p41) disposed below and the horizontal shaft member (p21) disposed spaced upward from it are provided as two separate elements, one binding portion ( 400). In this case, there is a vertical axis member (p12`) composed of the horizontal axis member (p21) disposed at the top and a vertical shaft member (p12``) composed of the horizontal maintaining shaft member (p41) disposed at the bottom, and together the vertical axis member It forms the concept of (p12). This configuration may make it convenient to assemble the necessary components one by one during manufacturing.

In response to this, the horizontal axis member (p21) and the anteroposterior extension member (221)/anterior and aft extension member (221a) are based on the anteroposterior (spacing) distance between the fixing part (100)/fixing member (110) and the rolling member (210). ) The total length of the combined composition is planned as is or by addition or subtraction. 6 (a) and 6 (b), if the length of the horizontal axis member (p21) in the front-to-back direction (y) is made small (c1)/large (c1'), on the contrary, the front-to-back extension member 221/front-to-back extension member The length of (221a) can appear large/small. When the length of the horizontal axis member (p21) is increased and a pivot joint is made with the front and rear extension members 221/front and rear extension members 221a, the middle (waist) of the joined part does not bend, and the vertical direction (z) ) can better withstand loads.

An extension member 220 is connected to each of the horizontal maintenance upper and lower extension members 321 of the left and right treads 300 in the vertical direction (z). A horizontal maintenance shaft unit (p30) is connected to the horizontal maintenance link member 322. A horizontal maintenance shaft unit (p50) is connected. are placed spaced apart from each other. The left and right horizontal maintaining shaft portions (p50) are disposed at both left and right ends of the horizontal maintaining link member 322, respectively, and are located in the middle between the left and right horizontal maintaining shaft portions (p50), that is, at the center of the horizontal length of the horizontal maintaining link member 322. , the horizontal maintaining shaft member (p42) is disposed. Since the horizontal maintaining shaft member (p42) of the tread portion 300 is rotationally connected to the horizontal maintaining shaft member (p41) of the binding portion 400 to form a link, the horizontal maintaining link member 322 is connected to the rolling portion 200. )/rolling member 210/left and right extension members 222 are tilted together according to the left and right inclinations, but the horizontal maintenance upper and lower extension members 321, which are rotatably connected to both left and right ends, do not tilt but move up and down. Through this configuration, a four-bar linkage combination that always maintains a parallelogram is provided.

Accordingly, in the examples of FIGS. 8 and 9, when the left and right tread parts 300 are stepped on alternately, they rise and fall (310 moves) in the up and down direction (z) in opposition to each other, and the left and right sides of the rolling part 200 The extension member 222 is tilted alternately to the left and right. At this time, the left and right horizontal maintaining shaft parts (p30) disposed at the left and right ends of the left and right extension members 222 also rise and fall in the up and down direction (z) contrary to each other, but the fixed part ( As long as 100) is not tilted and is standing upright in the vertical direction (z), the horizontal maintenance upper and lower extension members 321 linked to it always operate to stand upright in the vertical direction (z), and because of this, the stepping part (300)/Stepping member 310 always remains horizontal.

In addition, the horizontal axis portion (p20) becomes the central axis of the horizontal axis rotation (p20rotate) of the cloud portion 200, and together with the horizontal axis rotation (p20rotate), the vertical axis portion (p10) rotates the left and right vertical axis of the cloud portion 200 (p10rotate). ) In other words, it becomes the central axis of left and right rolling movement (210move) (swing movement) moving along an imaginary arc on the horizontal plane (xy). When a stepping motion (310move) is performed by alternately stepping on the left and right stepping parts (300) in the up and down direction (z), the rolling part (200) rotates in the vertical plane (xz)-(yz) with the horizontal axis part (p20) as the rotation center. /The horizontal axis rotates (p20rotate) alternately counterclockwise, and accordingly, the cloud part 200 rolling on the floor moves left and right along an imaginary arc with the vertical axis part (p10) as the rotation center on the floor on the horizontal plane (xy). It performs a left and right vertical axis rotation (p10rotate) that alternates direction with (x) and rolls.

Following the arc trajectory on the horizontal plane (xy) caused by this vertical axis rotation (p10rotate), the user can simultaneously experience a reciprocating motion that moves left and right and a twisting motion that changes the direction of the body. During such exercise, the user moves along the trajectory of circular motion and also changes the direction of looking, so the exercise path is varied and the direction of gaze changes, thereby reducing boredom.

Here, the radius of the virtual arc varies depending on the distance between the vertical axis portion (p10) and the rolling portion 200/rolling member 210, so that the size of the left and right reciprocating motion and the size of the twisting motion are set to be opposite (opposite). Accordingly, the distance can be scheduled or adjusted according to user characteristics, market demand, and production needs.

See Figures 8 and 9. When the user alternately steps on the left and right stepping members 310 to rotate the horizontal axis (p20rotate), the rolling member 210 rolls on the floor, causing a linear motion that reciprocates left and right and a vertical axis that causes a twisting motion that repeatedly changes direction to the left and right. Rotation (p10rotate) occurs simultaneously.

Here, the configuration in which both the fixing part 100 and the coupling part 400 are combined, in particular, depending on the arrangement (c3, c2, c1, c0) in the front-back direction (y) where the vertical axis (p10) is located, the rolling part 200 /The size of the straight width in the left and right direction (x) of the reciprocating motion of the rolling member 210 and the vertical axis rotation (p10rotate) of the twisted arc are set to be opposite (opposite) to each other. For example, the configuration of the vertical axis (p10) may be arranged on the same line (c2) as the front end of the left and right treads (300)/tread members (310) in the front-back direction (y), or it may be arranged (c1) behind them. Alternatively, it may be arranged (c1, c0) between the front and rear direction (y) lengths of the front and rear ends of the left and right treads 300/treading members 310. Therefore, it can be located in the middle of the body formed by the fixed part 100 and the rolling part 200. In the drawing example, for an appropriate combination of left and right movement and twist vertical axis rotation (p10rotate), the left and right treads 300 are shown disposed (c1) at the front end position or slightly spaced backwards from there.

If only a pure twisting movement is to be performed, the vertical axis (p10) is placed on the midline between the front and rear ends of the rolling part 200/rolling member 210, that is, at the center in the forward and backward direction (y) (c0) Just do it. In this case, the vertical axis rotation (p10rotate) is performed in place around the vertical axis (p10) disposed in the center of the front-to-back direction (y) length, thereby providing a completely pure twist movement function.

At this time, a restoration unit (restoration element) may be included in order to apply a load (resistance) to the movement (movement) and provide elastic restoration force (force to restore elasticity) back to the original position. The restoration unit hangs an elastic member (s10) between the vertical axis member (p11) of the fixing part (100) and the vertical axis member (p12) of the binding part (400), which is responsible for rotating the vertical axis (p10rotate) of the vertical axis part (p10). It can be configured by connecting the two to each other with an elastic member (s10). Alternatively, the restoration unit is between the horizontal axis member (p21) of the binding unit 400 and the horizontal axis member (p22)/rolling member 210 of the rolling unit 200, which is responsible for the horizontal axis rotation (p20rotate) of the horizontal axis unit (p20). It can be constructed by hanging an elastic member (s10). The elastic member s10 may be a lump provided as an elastic member such as metal, rubber, or synthetic resin, a spring (leaf spring, coil spring, etc.), a member using air pressure or hydraulic pressure, or a magnet member.

10 and 11, the elastic member s10 of the restoration part is a leaf spring member arranged to have a length in the front-back direction (y), and the front end of the elastic member s10 is connected to the horizontal axis member p21 of the binding portion 400. ) or fixed (connected so as not to rotate) to the body (or top) of the binding unit 400, and the rear end of the elastic member (s10) is fixedly connected to the body (or top) of the string part 212 of the rolling member 210. It is done. At this time, to facilitate fixation of the elastic member (s10), the horizontal axis member (p21), the string portion (212) of the rolling member (210), and both front and rear ends of the elastic member (s10) are provided with brackets (br: br1, br2) ( s10br) can be provided. In this way, the elastic member s10, whose ends are fixed and bound, exerts elastic force while twisting along the horizontal axis rotation (p20rotate), thereby applying resistance to movement or functioning to restore elasticity when the external force load weakens. .

In the examples of Figures 11 and 12,

The binding portion 400 is a long member taking the shape of a hollow pipe that is erected and arranged in the vertical direction (z), and the horizontal axis member (p21) of the binding portion 400 is perforated in the front/rear direction (y) at the front/rear thereof. (Formed by hollow grooves). That is, the horizontal axis member p21 is provided as a perforated groove. A shaft member (pn) is interposed in the horizontal shaft member (p21) in the form of a perforated groove to form a rotation axis.

And, the horizontal maintaining shaft member (p41) of the binding unit 400 is spaced downward in the vertical direction (z) from the horizontal axis member (p21) of the binding unit 400 and is perforated in the front-back direction (y). That is, the horizontal maintaining shaft member (p41) is provided as a perforated groove. And, a shaft member (pn) is interposed in the horizontal maintaining shaft member (p41) in the form of a perforated groove to form a rotation axis.

A cut groove (cut and perforated groove) is formed in the vertical direction (z) at the rear/front of the binding unit 400 and is provided as a bracket (br1) of the binding unit 400. And here, the front end of the elastic member s10 is interposed and fixed (fitted, fixed, coupled). For this purpose, the shape of the cutting groove is planned to correspond to the shear shape of the elastic member (s10). Here, even if the front end of the elastic member (s10) is simply inserted into the bracket (br1) provided as a cut groove, the front end is blocked without being cut inside the hollow interior of the pipe-shaped long member, so the front end of the elastic member (s10) is blocked. It gets stuck in the incision groove and is blocked from the top, bottom, left, and right as well as the front.

Through the above configuration of the binding portion 400, the components added with just one pipe-shaped length member can be simply and easily provided, which is advantageous in manufacturing.

The string portion 212 has a cut groove formed in the vertical direction (z) corresponding to the rear end of the elastic member s10 at the center portion of the left and right lengths. Here, the rear end of the elastic member s10 is interposed and fixed to serve as the bracket br2 of the string portion 212. At this time, a fixing groove may be drilled at the rear end of the elastic member s10 so that it can be fixed with a fixing member (screw, bolt, etc.) to serve as a bracket s10br for the elastic member s10. On the other hand, when the rolling part 200 makes a rolling motion and is tilted to the left and right, a suspension is installed at the bottom (lower part) of the rolling member 210/housing part 211 to avoid contact and interference with the stepping member 310. (212) can be placed. At this time, as in the example, the string portion 212 takes a '⊥' shape with the middle portion of the left and right lengths protruding upward, so that the height of the middle portion can be adjusted to correspond to the installation of other components.
