[0012] The present invention relates to a two-stage footrest that is placed in front of a chair under a desk or various tables to allow a user to work or rest in a comfortable position by placing the feet or calves on it. The embodiment of the present invention will be described below with reference to the accompanying drawings.

[0013] -Note- A two-stage footrest including a lower foothold support means on which a lower foothold provided at a lower part is installed, and an upper foothold support means on which an upper foothold provided at an upper part of the lower foothold support means is installed, so that the footrest can be placed on an indoor floor in front of a chair under a desk or table and the feet or calves can be selectively placed on the footrest to work or rest in a comfortable position, The lower scaffolding support means 10 is formed in an "L" shape when viewed from the side, and supports 31 are rotatably installed on both sides of the lower part of the "L"-shaped lower scaffolding support means. The lower scaffolding 30 is installed on the supports so as to have a slope that slopes downward from the rear to the front, making it possible to place the feet comfortably on it and to use it. The lower scaffolding can be folded and unfolded for use, and the lower scaffolding is formed so that the lower scaffolding is inclined downward from the top to the bottom so that it cannot be unfolded arbitrarily after being folded upward. The lower scaffolding is composed of a lower scaffolding fixing part 11 formed so as to slope downward from the top to the bottom, and a lower connecting part 12 formed upward on both sides of the rear end part of the lower scaffolding fixing part, The upper scaffolding support means 20 has a "U"-shaped upper portion and is formed in an inverted "L"-shaped portion when viewed from the side. The upper scaffolding 40 is rotatably installed at the upper portion of the "U"-shaped portion, and the upper scaffolding can be folded and unfolded for use. The upper scaffolding includes an upper scaffolding fixing portion 21 formed so that the upper scaffolding is inclined downward from top to bottom so that the upper scaffolding cannot be unfolded arbitrarily after being folded upward, and an upper connecting portion 22 formed downward on both sides of the rear end portion of the upper scaffolding fixing portion.

[0014] The two-stage footrest of the present invention having the above-mentioned configuration is used by being placed on an indoor floor in front of a chair under a desk or table. As shown in Figs. 3 and 4, the upper and lower footrests 30 and 40 are installed at a certain distance from each other, so that a user can work or rest in a comfortable position by placing his / her feet on the lower footrest 30 and his / her feet or calves on the upper footrest 40 while sitting on a chair.

[0015] The upper and lower scaffolding support means 10, 20 on which the upper and lower scaffoldings 30, 40 are installed are either integrally connected to each other as shown in FIG. 5a, or are formed so as to be separable and connectable as shown in FIG. 5b, so that the distance between the upper and lower scaffoldings 30, 40 can be adjusted by adjusting the height of the upper scaffolding support means 20 on which the upper scaffolding 40 is installed from the lower scaffolding support means 10 on which the lower scaffolding 30 is installed.

[0016] The reason for adjusting the distance between the upper and lower footholds 30, 40 as described above is to vary the distance between the upper and lower footholds 30, 40 according to the user's physical condition, i.e., leg size, so that the upper and lower footholds 30, 40 can be positioned at the most comfortable position for the user.

[0017] The upper and lower scaffolding support means 10, 20 on which the above-mentioned upper and lower scaffolding 30, 40 are installed are preferably formed of a hollow circular or square pipe-shaped frame, but any other upper and lower scaffolding support means 10, 20 that can install the upper and lower scaffolding 30, 40 and adjust the height of the installed upper and lower scaffolding 30, 40 may be used.

[0018] The reason why the upper and lower scaffolding support means 10, 20 are made into hollow circular or square pipe-shaped frames is to make it easier to bend and deform the boundary portions between the upper and lower scaffolding fixing parts 11, 21 and the upper and lower connecting parts 12, 22 provided on the upper and lower scaffolding support means 10, 20 when the upper and lower scaffolding support means 10, 20 are connected to each other and formed as a single unit, and to make it easier to adjust the height of the upper and lower scaffolding fixing parts 11, 21 when the upper and lower scaffolding support means 10, 20 are formed so that they can be separated and connected.

[0019] As shown in Figure 5b, the lower scaffolding support means 10 positions the lower scaffolding fixing parts 11 on which the lower scaffolding 30 is attached so that they are maintained at a fixed distance on both sides of the lower part, and upwardly facing lower connecting parts 12 are formed at the rear ends of the lower scaffolding fixing parts 11 on both sides. The lower scaffolding 30 is positioned on the lower scaffolding fixing parts 11, and the lower connecting parts 12 are made to be able to fit into the upper connecting parts 22 described later.

[0020] In addition, the upper scaffolding support means 20 has an upper scaffolding fixing part 21 formed at the upper part, on which the upper scaffolding 40 is provided, and upper connecting parts 22 which are connected to the lower connecting parts 12 are formed facing downward at the rear ends on both sides of the upper scaffolding fixing part 21, and the upper scaffolding 40 is positioned on the upper scaffolding fixing part 21, and the upper connecting parts 22 are fitted into the lower connecting parts 12 mentioned above.

[0021] The lower scaffolding support means 10 having the above-mentioned lower scaffolding fixing part 11 and lower connecting part 12 is preferably formed in an inverted "L" shape, and the upper scaffolding support means 20 having the upper scaffolding fixing part 21 and upper connecting part 22 is formed in an inverted "L" shape when viewed from the side, and the upper tip of the inverted "L" shape can be formed into a "I" shape or a "U" shape for use.

[0022] When the upper scaffolding fixing part 21 is U-shaped, the upper scaffolding 40 can be folded upward as shown in Figure 9 and the feet can be placed on the U-shaped upper scaffolding fixing part 21.

[0023] In addition, the upper and lower scaffolding support means 10, 20 are formed to be adjustable in height, and the height is adjusted by slidably engaging the lower connecting part 12 formed on the lower scaffolding support means 10 with the upper connecting part 22 formed on the upper scaffolding support means 20, and after the height is adjusted in this engaged state, the height is fixed using a fixing means 50 that fixes the adjusted height so that it does not change.

[0024] As shown in FIG. 5b, the fixing means 50 is configured such that a stopper 51 is provided on one of the upper and lower connecting parts 12, 22, and holes 52 are formed at regular intervals along the longitudinal direction on the other connecting part. When the stopper 51 and the hole 52 are aligned with each other, the stopper 51 is connected to the hole 52.

[0025] The fixing means 50 described above is one embodiment of the present invention, and any other configuration is possible as long as it fixes the upper and lower scaffolding support means 10 and 20 so that the adjusted height does not change after the height is adjusted.

[0026] In addition, as shown in Figures 5a and 5b, the lower scaffolding support means 10 of the present invention has an upper part connected to a lower scaffolding fixing part 11 and a protective member P supported on the indoor floor installed at the lower part, and the lower scaffolding fixing part 11 does not directly contact the indoor floor but contacts the protective member P, thereby preventing the generation of friction noise between the lower scaffolding fixing part 11 and the indoor floor and protecting the lower scaffolding support means 10.

[0027] In addition, as shown in FIG. 6a, the lower scaffolding 30 of the present invention is preferably formed by installing a support 31 fixed to the lower scaffolding support means 10 and a plurality of horizontal bars 32 on the support so as to be spaced at regular intervals, but any other structure that can be used by placing feet on it is also acceptable.

[0028] In addition, when not in use, the lower scaffolding 30 can be rotated upward and folded upward as shown in Figure 9, and when in use, the folded lower scaffolding 30 can be returned to its original position and used as shown in Figures 3 and 4.

[0029] As shown in FIG. 6a, the lower foothold 30 having the above-mentioned function is formed such that the thickness T of the support 31 forming the lower foothold 30 gradually decreases from the rear where the lower joint 12 is located to the front toward the chair, and the surface of the lower foothold 30 has a slope that slopes downward from the rear to the front, allowing the user to comfortably place their feet on the lower foothold 30.

[0030] In addition, the rotation of the lower scaffold 30 of the present invention is performed by a lower scaffold rotating means 60 installed by connecting between the lower scaffold fixing part 11 of the lower scaffold supporting means 10 and the lower scaffold 30, as shown in Figures 6a to 6c.

[0031] One embodiment of the lower scaffolding rotation means 60 is configured with a central pin 61 that is installed through the lower scaffolding 30 and the lower scaffolding fixing part 11, and when the lower scaffolding 30 rotates, it is rotated around the central pin 61 as an axis and folded upward as shown in Figure 9.

[0032] In addition, a lower scaffold angle conversion means 70 is installed at the bottom of the lower scaffold 30 of the present invention to enable the angle of the lower scaffold 30 to be changed from the lower scaffold fixing part 11. The reason for this is to maintain the optimal angle according to the user's physical condition so that the user can place their feet on it in the most comfortable position while seated on the chair.

[0033] The configuration of the first embodiment of the lower scaffolding angle conversion means 70, as shown in Figure 6b, is such that a lower screw bolt 71 is installed at the front lower part of the support 31, and the distance between the front of the lower scaffolding fixing part 11 and the indoor floor is varied depending on the direction of rotation of the screw bolt 71, thereby changing the inclination of the lower scaffolding 30 and adjusting the inclination of the upper surface of the lower scaffolding 30.

[0034] As shown in Figure 6c, the second embodiment of the lower scaffolding angle conversion means 70 is configured by freely rotatably installing a polygonal lower eccentric rotor 72 which rotates about a central axis on the front side of the support 31 which forms the lower scaffolding 30, and by changing the distance between the front of the lower scaffolding fixing part 11 and the indoor floor depending on the direction of rotation of the lower eccentric rotor 72, the inclination of the lower scaffolding 30 changes, thereby adjusting the inclination of the upper surface of the lower scaffolding 30.

[0035] The reason for forming the polygonal lower eccentric rotor 72 is that when the lower eccentric rotor 72 is rotated, the upper surface of the rotated lower eccentric rotor 72 and the lower surface of the lower scaffolding 30 come into surface contact with each other, thereby providing a safe supporting force.

[0036] In addition, as shown in Figures 7a to 7d, the upper scaffolding 40 of the present invention has an upper scaffolding rotating means 80 for rotating the upper scaffolding installed between the upper scaffolding support means 20 and the upper scaffolding 40, so that the upper scaffolding 40 can be rotated upward and folded upward as shown in Figure 9.

[0037] The upper scaffold 40 being folded upward as described above and below means that the upper scaffold 40 is bent upward.

[0038] Furthermore, as shown in FIG. 7a, the upper scaffolding rotation means 80 of the first embodiment of the present invention is composed of a connector 82 having one side fixed to the upper scaffolding 40 and the other side formed with a connecting part 82b that is rotatably installed on the upper scaffolding fixing part 21 via a fixing pin 82a.

[0039] The method of rotating the upper scaffolding 40 using the connecting device 82 of the first embodiment is that when the upper scaffolding 40 is operated upward, the connecting part 82b rotates around the fixed pin 82a as an axis, causing the upper scaffolding 40 to fold upward as shown in Figure 9.

[0040] In addition, as shown in Figure 7b, the upper scaffolding rotation means 80 of the second embodiment of the present invention is connected to the upper scaffolding fixing part 21 at the rear, and has a storage part 83b with a long hole 83a formed in the center into which a guide 83d formed on the upper scaffolding fixing part 21 is fitted, and is composed of a connecting member 83 at the end of the storage part, on which an extension part 83c fixed to the upper scaffolding 40 is formed so as to face each other.

[0041] The method of rotating the upper scaffolding 40 using the connecting member 83 of the second embodiment is such that, when the upper scaffolding 40 is operated upward, the connecting member 83 rotates about the upper scaffolding fixing part 21 as an axis, and at the same time, the long hole 83a rotates while being guided by the guide 83d, so that the upper scaffolding 40 is safely folded upward without moving.

[0042] In addition, as shown in FIG. 7c, the upper scaffolding rotating means 80 of the third embodiment of the present invention is a rotating member 84 having a fixed part 84a formed on one side to be fixed to the upper scaffolding 40, and a rotating part 84c formed on the other side to penetrate the upper scaffolding fixed part via a fixing pin 84b and rotate.

[0043] In the method of rotating the upper scaffolding 40 utilizing the pivoting member 84 of the third embodiment, when the upper scaffolding 40 is operated upward, the pivoting portion 84c, which is a component of the pivoting member 84, is pivoted about the fixed pin 84b as an axis, so that the upper scaffolding 40 is safely folded upward without moving.

[0044] In addition, the upper scaffolding rotating means 80 of the fourth embodiment of the present invention is composed of either one of a hinge or a hinge 85 that connects the upper scaffolding 40 and the upper scaffolding fixed part 21, as shown in FIG. 7d.

[0045] In the method of rotating the upper scaffolding 40 using the rotating member 84 of the fourth embodiment, when the upper scaffolding 40 is operated upward, the upper scaffolding 40 is safely folded upward by the hinge 85 without moving its position.

[0046] An operating tool H is provided on the upper scaffold 40 so that the upper scaffold 40 can be easily operated when it is moved upward.

[0047] The upper scaffolding 40 of the present invention as described above includes an upper scaffolding support panel 41 fixed to the upper scaffolding fixing part 21, and an upper scaffolding member 42 fixed and installed on the upper scaffolding support panel 41, and the upper scaffolding member 42 is supported by the upper scaffolding support panel 41, and it is preferable that the upper scaffolding member 42 has cushioning force.

[0048] In addition, as shown in Figures 8a to 8c, an upper scaffold angle changing means 90 is installed at the bottom of the upper scaffold 40 of the present invention, the lower end of which comes into contact with the upper scaffold fixing part 21 to change the angle of the upper scaffold 40, thereby changing the angle of the upper scaffold 40 according to the user's physical condition, so that the user can place his / her feet or calves at the most comfortable angle.

[0049] The first embodiment of the upper scaffolding angle conversion means 90 having the above-mentioned function is configured by installing an upper screw bolt 91 for adjusting the distance between the upper scaffolding fixing part 21 and the lower part of the upper scaffolding 40, as shown in FIG. 8a. Depending on the direction of rotation of the upper screw bolt 91, the distance between the upper scaffolding 40 and the upper scaffolding fixing part 21 changes, and the inclination angle of the upper scaffolding 40 changes.

[0050] In addition, the upper scaffolding angle conversion means 90 of the second embodiment is configured by installing a spacing retainer 92 that adjusts the distance between the upper scaffolding fixing part 21 and the lower part of the upper scaffolding 40, as shown in Figure 8b, and the inclination angle of the upper scaffolding 40 changes as the distance between the upper scaffolding 40 and the upper scaffolding fixing part 21 changes depending on the height of the spacing retainer 92.

[0051] In addition, the upper scaffolding angle conversion means 90 of the third embodiment is a polygonal upper eccentric rotor 93 having a coupling groove 93a that fits tightly into the upper scaffolding fixing part 21 so as to adjust the distance between the upper scaffolding fixing part 21 and the lower part of the upper scaffolding 40, as shown in FIG. 8c, and the inclination angle of the upper scaffolding 40 changes as the distance between the upper scaffolding 40 and the upper scaffolding fixing part 21 changes depending on the rotation direction of the upper eccentric rotor 93.

[0052] The upper scaffolding angle conversion means 90 is preferably installed at a position at the lower rear of the upper scaffolding 40, because the inclination angle between the front and rear of the upper scaffolding 40 can be varied by adjusting the height of the lower rear of the upper scaffolding 40.

[0053] The reason why a polygonal upper eccentric rotor 93 is used in the upper scaffolding angle conversion means 90 is that when the upper eccentric rotor 93 is rotated, the upper surface of the rotated upper eccentric rotor 93 and the upper surface of the upper scaffolding 40 come into surface contact with each other to exert a safe supporting force.

[0054] Meanwhile, a stimulating member M for acupressure or massage of the sole or calf is formed on the surface of either or both of the upper and lower scaffolds 30, 40, so that the sole or calf placed on the upper and lower scaffolds 30, 40 can be acupressure or massaged.

[0055] In addition, in order to prevent the upper and lower scaffolds 30 and 40 of the present invention from being arbitrarily unfolded as shown in Figs. 3 and 4 after being folded upward as shown in Fig. 9, the folded upper and lower scaffolds 30 and 40 are formed to be inclined downward when folded upward.

[0056] In order to prevent the upper and lower scaffolds 30, 40 from being arbitrarily opened when folded upward as described above, the distance between the rotation points of the upper and lower scaffold rotating means 60, 80 of the upper and lower scaffolds 30, 40 installed on the upper and lower scaffold fixing parts 11, 21 and the rear ends of the upper and lower scaffold fixing parts 11, 21 is formed wider than the thickness of the upper and lower scaffolds 30, 40.

[0057] As described above, the two-stage footrest of the present invention is positioned in front of a chair under a desk or various tables, so that a user can work or rest in a comfortable position by placing his / her feet or calves on it, as described in the effects above. The angle of the upper or lower scaffold can be adjusted as necessary to an angle that is easy for a user to use. When the upper scaffold is not in use, the upper scaffold can be folded upward and maintained in the folded state without being arbitrarily unfolded. The upper and lower scaffolds can be installed on the upper and lower scaffold support means, respectively, and can be selectively used. This has the advantage that a user can work or rest in a comfortable position by placing his / her feet or calves on it.
