Description

[Background technology]

[0001] The present invention relates to a posture correction device for correcting posture when standing or sitting, and a method for using the posture correction device.

[0002] Since ancient times, there have been many tasks performed while sitting at a desk. Stretching both arms forward to work on a desk top that is horizontal to the ground causes the center of gravity to deviate forward when sitting. This causes the spine to act like a wall when a heavy object is placed on a cantilevered shelf. If the spine cannot withstand this force, it will lean forward, often resulting in a hunched posture. This is promoted by the backward rotation of the pelvis. By tilting the pelvis backward, the sitting posture is maintained not by the support of the spine but by the tension limit of the soft tissues on the back. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2002-238930 A [Patent Document 2] JP2015-142716A [Patent Document 3] Special publication 2013-528425 Summary of the Invention [Problem to be solved by the invention]

[0004] A posture correction supporter (see, for example, Patent Document 1), which is a type of health and medical device, has the function of maintaining the body in a predetermined posture by being attached to a predetermined position on the body. The posture correction supporter can change the body from a bad posture such as a hunched back to a good posture such as an upright back and maintain this posture, but when the posture correction supporter is removed, the body tends to return to the original bad posture over time. Also, the posture correction supporter cannot always be worn.

[0005] Therefore, Patent Document 2 achieves posture correction using a device equipped with an EMS (Electrical Muscle Stimulation) electrode pair, while Patent Document 3 achieves posture correction using a device equipped with a posture detection sensor, etc. However, both inventions have complicated structures and methods of use, which not only increase production costs but also pose high barriers to casual implementation. [Means for solving the problem]

[0006] In order to solve the above problems, the invention of claim 1 is a device for correcting posture when standing or sitting, characterized in that it comprises a palm contact part with a height of 10mm to 20mm, a depth of 50mm to 70mm, and a width of 20mm to 40mm, the palm contact part having a semi-oval upper surface and a flat lower surface, and a lower installation part attached to the flat lower surface of the palm contact part.

[0007] The invention of claim 4 is a method of using a corrective device to correct a standing or sitting posture, characterized by including the steps of preparing a corrective device that is fixed to a desk, workbench, or operating table and has a height of 10 mm to 20 mm, a depth of 50 mm to 70 mm, and a width of 20 mm to 40 mm, placing the palm of the hand on the corrective device, applying the weight of the body to the corrective device, and receiving a reaction force from the corrective device to the body. Effect of the Invention

[0008] According to this device, posture correction, which is difficult to achieve through awareness alone, can be achieved simply by determining the position of the shoulder joints and palms, and posture can be maintained simply by placing the posture correction device in the designated position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, the embodiment of the present invention will be described with reference to the attached drawings. The following embodiment is an example for explaining the present invention, and is not intended to limit the present invention to the embodiment. Furthermore, the present invention can be modified in various ways without departing from the gist of the invention. Furthermore, the same components in each drawing are assigned the same reference numerals as much as possible, and duplicated explanations are omitted.

[0011] <Principle of action and effect> The weight balance of the body will be explained using Figures 1 and 2. Figure 1 is a diagram explaining the weight distribution of the upper limbs of the body, and Figure 2 is a diagram explaining the sagittal plane weight distribution when the elbow joint is flexed.

[0012] As shown in FIG. 1, the weight balance of the upper limbs is the upper arm U between the shoulder joint 10 and the elbow 20, the forearm M between the elbow 20 and the wrist 30, and the palm L, and the weight balance is U:M:L=3:2:1.

[0013] As shown in Figure 2, when the elbow 20 is pulled backward to achieve a 2:1 arrangement along a line SL extending vertically from the shoulder joint 10, the weight balance of the upper limbs and the body along the line SL becomes 1:1, and does not become a factor in losing posture when standing or sitting. However, when the position of the upper limbs moves forward of the line SL extending vertically from the shoulder joint 10 beyond 2:1, the center of gravity of the body also becomes more heavily weighted forward, and the body tends to lean forward. Based on this characteristic, the following embodiment of the present invention will be described.

[0014] <Embodiment> Next, the posture correction device 100 according to the embodiment of the present invention will be described with reference to Fig. 3 to Fig. 8. Fig. 3 is a perspective view of the posture correction device 100 according to the embodiment of the invention, Fig. 4 is a front view of the posture correction device 100 according to the embodiment of the invention, Fig. 5 is a top view of the posture correction device 100 according to the embodiment of the invention, Fig. 6 is a bottom view of the posture correction device 100 according to the embodiment of the invention, Fig. 7 is a right side view of the posture correction device 100 according to the embodiment of the invention, and Fig. 8 is a right side view of the posture correction device 100 according to the embodiment of the invention. The back view is omitted because it is the same as the front view of Fig. 5.

[0015] As shown in Fig. 3 to Fig. 8, the posture correction device 100 is composed of a palm contact part 101, the upper surface of which is semi-oval and the lower surface of which is flat, and a lower grounding part 102 attached to the lower surface of the palm contact part 101. When used with one hand, one posture correction device 100 functions as one device, and when used with both hands, a pair of posture correction devices 100 functions as one device. When performing tasks such as keyboard input, the posture correction device 100 is placed under the palm part L. Keyboard operation is usually performed with the wrist joint in contact with the desk surface, and not only left and right movements are performed by radial flexion and ulnar flexion of the wrist joint, and distance and near operations are performed by slight dorsiflexion and palmar flexion, but also spiral movements are present, and when moving toward the center, in addition to radial flexion of the wrist joint, pronation of the forearm is also present. In order not to interfere with the pronation movement, an egg-shaped shape that fits the palm is desirable.

[0016] Palm contact portion 101 and lower installation portion 102 are adhered together with an adhesive or the like so that they do not come apart. The material of palm contact portion 101 is not important, but in consideration of weight, ease of processing, and cost, it is preferably made of wood or a polymeric material, and more preferably made of cypress. The material of the lower installation portion is also not important, but in consideration of the need for anti-slip functionality, rubber, polypropylene, polyethylene, urethane, or acrylic foam is preferred. Palm contact portion 101 and lower installation portion 102 may be made of the same material, in which case adhesive or the like need not be used.

[0017] The posture correction device 100 has a height H of 5 mm to 30 mm, preferably 10 mm to 20 mm, and more preferably 16 mm to 18 mm, a depth D of 30 mm to 100 mm, preferably 50 mm to 70 mm, and more preferably 60 mm to 70 mm, and a width W of 10 mm to 50 mm, preferably 20 mm to 40 mm, and more preferably 25 mm to 35 mm, taking into consideration the height that generates resistance from near the wrist joint, support up to the height of the pisiform and trapezoid bones that come into contact with the desk, ease of rotation and gliding of the palm, and minimizing restrictions on palmar dorsiflexion.

[0018] <Method 1> A posture correction method according to an embodiment of the present invention will be described with reference to Figures 9 to 11. Figures 9 to 11 are diagrams showing steps of the posture correction method according to the embodiment of the present invention.

[0019] (Step S1) First, as shown in FIG. 9, the corrective device 40 is installed at two places on a desk 50 or a computer 60. As shown in FIG. 10, the corrective device 40 may be installed at only one place, and the grounding position may be the right or left. The corrective device 40 may be a posture corrective device 100 or a simple convex part. The type of desk 50 is a table such as a normal office desk, study desk, washstand, work table, or operation table, and may be used while standing or sitting. The corrective device 40 has a height of 5 mm to 30 mm, preferably 10 mm to 20 mm, and more preferably 16 mm to 18 mm, a depth of 30 mm to 100 mm, preferably 50 mm to 70 mm, and more preferably 60 mm to 70 mm, and a width of 10 mm to 50 mm, preferably 20 mm to 40 mm, and more preferably 25 mm to 35 mm. The distance 40H between the two points of the corrective device 40 is desirably the width of both wrists when typing on a keyboard such as a computer, and is 50 to 600 mm, preferably 100 to 400 mm, and more preferably 120 to 200 mm.

[0020] (Step S2) Next, the person 1 stands or sits as shown in FIG.

[0021] (Step S3) As the work progresses, Person 1's weight begins to shift forward.

[0022] (Step S4) The load applied in step S3 receives a reaction force from the corrective device 40, and a force is applied in the opposite direction to the load. This reaction force corrects the posture, and the back muscles of the person 1 become parallel to the line SL that is extended vertically from the shoulder joint 10.

[0023] <Embodiment 2> Next, a method for correcting posture using the posture correction device 100 according to the embodiment of the present invention will be described with reference to Fig. 12. Fig. 12 is a diagram showing steps of a method for correcting posture by placing a palm portion L represented by bones on the posture correction device 100 according to the embodiment of the present invention.

[0024] (Step S11) First, as shown in FIG. 12, similarly to step S3, the posture correcting device 100 is placed in a state in which the weight of the person 1 is applied, and a force is applied to the wrist 30 of the palm portion L.

[0025] (Step S12) The anti-slip effect of the lower installation part 102 of the posture correction device 100 works, and a force opposite to that in step S11 is applied to the wrist 30 of the palm part L, and a pushing back reaction force acts on the person 1. The posture of the person 1 is corrected by using this reaction force. [Explanation of symbols]
