Description
Detailed Description of the Invention
Technical Field
[0001] The present invention relates to a functional health chair for stimulating the acupoints of traditional Chinese medicine finger pressure to provide health promotion.
Background Art
[0002] The basic function of a chair is to support the upper body of the seated person during rest and work. A chair generally consists of an assembly that supports the buttocks and lumbar spine, and includes springs, cushions, or pads placed on springs. When using a chair, the seated person generally takes two characteristic postures, which include a posture of leaning back to rest and a posture of bending forward to work.
[0003] The chair must appropriately deform to these two specific postures taken by the seated person and support the seated person's body. Many chairs that can keep the upper body of the seated person in a relaxed and good posture during rest have been introduced. Although the chair has a backrest, most of the structures cannot adjust such a backrest, so when the seated person sits on the chair for a long time, they are likely to get tired, and there are problems such as nerve compression phenomenon in the lumbar spine and spinal deformation. Therefore, research on functional chairs to solve such problems is required.
[0004] A conventional chair seat body (1) has a seat (3) and a backrest (4), and the leg member (2) has a front leg (12) that follows the seat (3) of the chair seat body (1) and a floor frame (13) that follows the backrest (4) in a continuous line. The front leg (12) of this leg member (2) is pivotally attached to the seat (3) by a pivot (15). As a result, the leg member (2) can rotate between a folded position that follows the chair seat body (1) and an unfolded position where the front leg (12) stands upright below the seat (3) and the floor frame (13) follows the floor surface. In the unfolded position, a rear leg (9) is pivotally attached (19) to the floor frame (13) so that it is in an upright position. The tip of the rear leg (9) engages with an engagement part (20) of the seat body (1) in the unfolded position. When the above-mentioned leg members are in the extended position, it becomes a chair with legs, and when they are in the folded position, it becomes a floor chair. This is disclosed in the following patent document. [Patent Document 1] Japanese Patent Publication No. 11-113680 [Patent Document 2] Design Registration Gazette, Design Registration No. 1684500
[0005] An embodiment of Patent Document 1 is shown in the explanatory diagram of Figure 4. Specifically, one end of the rear leg (9) is pivotally attached (28) to the seat portion (3) of the chair seat body (1), and a guide shaft (29) provided at the other end of the rear leg is designed to engage with an engaging portion (30), such as an engaging groove, provided in the floor frame (13) of the leg member (2). Furthermore, a guide groove (31) is provided in the floor frame (13) of the leg member (2) to guide the guide shaft (29) provided at the other end of the rear leg (9), thereby guiding the movement of the rear leg when the leg member (2) moves between the folded and unfolded positions. This is because the material of the chair seat is not plastically deformable. [Disclosure of the Invention] [Problems that the invention aims to solve]
[0006] In contrast to the shortcomings and drawbacks of conventional technology, the objective of the present invention is to maximize the effect of acupressure on the lumbar spine of a person sitting in a functional health chair while efficiently supporting their back. 1) This involves applying acupressure using protrusions that correspond to acupuncture points in the buttocks and lower back of the human body. 2) Since the person sitting in the functional health chair will also be performing stretching exercises, the mechanical strength of the chair must be commensurate with this. 3) It must be a structure that contributes to the prevention of spinal stenosis and performs its function accordingly. 4) It must have a structure and function that contributes to "Yin Yoga stretching." [Means for solving the problem]
[0007] To solve these problems, the inventors have come up with the present invention described below. 1) In a functional health chair, the locations of acupressure points in Oriental medicine have been clearly defined, and protrusions corresponding to those points have been provided. 2) In the functional health chair, in order to ensure its mechanical strength, the materials used were nylon synthetic resin and polyester fabric, and the mechanical compressive strength was increased to 380 kg or more through injection molding. 3) In order to contribute to the prevention of spinal stenosis in a functional health chair, the structure was designed with an S-shape that corresponds to the anatomical and ergonomic aspects of the spine in order to achieve this function. 4) In the functional health chair, the structure and shape were designed to contribute to "yin yoga stretching" and to enable it to perform. 5) In the functional health chair, the individual components of its structure were as follows: In one aspect of the present invention, the functional health chair of the present invention includes a first plate portion that accommodates the buttocks and thighs when a person sits on the chair, a second plate portion that accommodates the waist and back when a person sits on the chair, and a connecting portion that connects the first plate portion and the second plate portion, wherein the second plate portion may have a pressure point portion that comes into close contact with the waist when a person sits on the chair.
[0008] In other words, the lower end of the acupressure portion is connected to the connecting portion, the upper and side ends of the acupressure portion are separated from the second plate portion, and the acupressure portion is formed in a region at the central position of the second plate portion, and can provide the function of applying pressure and supporting the lumbar region.
[0009] In one embodiment of the present invention, when the seated person sits on the chair and leans their back against the second plate, the second plate and the acupressure part are deformed elastically, and the second plate and the acupressure part can have different restoring forces.
[0010] The acupressure portion has elasticity and deforms to conform to the sitter's waist when the sitter sits on the chair, and includes a plurality of protrusions to further enhance the acupressure effect on the waist.
[0011] When the person sitting on the chair leans their body against the back, the front of the first plate is lowered by the weight (body weight) of the person sitting, and the acupressure portion can provide an acupressure effect to the lower back with a stronger restoring force than the other parts of the second plate. [Effects of the Invention]
[0012] According to the present invention, when a person sits in a functional health chair, the effect of acupressure on the sitter's lumbar spine can be maximized while efficiently supporting the back. 1) In a functional health chair, the location of acupressure points in Oriental medicine is clearly defined, and protrusions corresponding to those points are provided, thereby enabling the acquisition of acupressure effects. 2) In the functional health seat, in order to ensure its mechanical strength, the materials are nylon synthetic resin and polyester fabric, and through processing by injection molding, the mechanical compressive strength is made 380 kg or more, enabling the seated person to safely perform stretching exercises of arching and arching back on the functional health seat. 3) In order to give play to its function in a structure that "prevents spinal stenosis in the functional health seat", from the anatomical and ergonomic perspectives of the spine, it is made into an S-shaped structure corresponding to this, so that the spine can be corrected into an S-shaped structure. 4) In the functional health seat, in order to give play to the structure and its function that contribute to "yin yoga stretch", by making it into a corresponding shape, it can respond to stretching exercises. 5) In the functional health seat, by making it into a seat structure, it can be used on a sofa, on a bed, outdoors, on a bench without a backrest, on the driver's seat of a car, etc.

Modes for Carrying Out the Invention
[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the overall shape of the functional health seat 100 according to an embodiment before use 710 (left) and during use 720 (right). FIG. 2 shows the positions of the acupuncture points of the buttocks and waist of the human body in traditional Chinese medicine. FIG. 3 shows a bird's-eye view of the functional seat 100. FIG. 4 shows the implementation status of a chair seat made of a non-flexible material described in Patent Document 1 (left figure), and the implementation status diagram of a chair described in Patent Document 2 in which the seat can slide forward by the user and the inclination angle of the backrest becomes loose when sliding forward (right figure). FIG. 5 shows the test state of the strength of the functional health seat of the present invention. FIG. 6 is an explanatory diagram contributing to the "prevention of spinal stenosis" of the functional health seat of the present invention. FIG. 7 is an explanatory diagram contributing to the "yin yoga stretch" of the functional health seat of the present invention. FIG. 8 is an explanatory diagram contributing to the "stretching exercise" of the functional health seat of the present invention.
[0015] Referring to FIG. 1, the reference number (710) represents the state where the seated person is not sitting on the functional health seat (100), and (720) indicates the state where the seated person is sitting on the functional health seat (100). Similar to the case of the reference number (710), before the seated person sits on the functional health seat (100), the acupressure part (140) including the protrusion part (145) protrudes forward from the peripheral surface of the second plate part (130). Similar to reference number (720), when a person sits on the functional health chair (100) and presses their body against the backrest, the connecting part (120) and the second plate part (130) will deform elastically. When a person sits on the functional health chair (100), the front of the first plate part (110) moves downward due to the weight of the person sitting, and the connecting part (120) and the second plate part (130), which are integrally formed with the first plate part (110), come into close contact with the user's waist and back, providing a specific elastic force. The second plate part (130) can have a shape that is curved forward in the longitudinal direction, and with such a shape, the second plate part (130) has a form that can support the waist and back when the person sits on the functional health chair (100), so that the person's waist and other parts are closely supported by the second plate part (130). As shown in Figure 1A, the second plate portion 130 is configured to protrude forward from the connecting portion 120. As shown in Figure 1B, the second plate portion 130 is configured to be curved so that when a person is seated, it is pushed forward and fits snugly against the lower back and back of the person being seated, providing support. Referring to the diagram in Figure 2, it can be clearly seen that the acupoints in the buttocks and lower back of the human body in Oriental medicine are distributed symmetrically on both sides, centered around the spine. Referring to the drawing in Figure 3, the functional health chair 100 specifically shows a functional health chair equipped with a shiatsu massage section 140. The functional health chair 100 has a first plate section 110, a second plate section 130, and a connecting section 120 that connects the first plate section 110 and the second plate section 130. The first plate portion 110 accommodates the buttocks and thighs when a person sits on the functional health chair 100, and the second plate portion 130 accommodates the waist and back when a person sits on the functional health chair 100. The first plate portion 110, the second plate portion 130, and the connecting portion 120 are formed as a single unit.
[0016] The first plate portion 110 is a seat plate on which the thighs and buttocks of a seated person are placed or arranged, and is shaped so that the front is slightly raised upwards. Depending on the embodiment, the first plate portion 110 may also be equipped with a removable plate-shaped cushion 115. The first plate portion 110 is preferably a dish shape with an arc angle of 6 to 8 degrees.
[0017] The second plate portion 130 is formed as a backrest that extends behind the connecting portion 120 and supports the lumbar and back portions of the seated person. The second plate portion 130 has an appropriate curve to ensure close contact with the lumbar and back portions and may be connected to the first plate portion 110 via the connecting portion 120. The second plate portion 130 can be formed, for example, to curve forward in the longitudinal direction.
[0018] The connecting portion 120 is the area where the seated person's buttocks are located when the seated person sits on the functional health chair 100, and may be formed in a curved shape as shown in the figure. The connecting portion 120 and the second plate portion 130 may include a flexible material that provides elastic force. Depending on the embodiment, not only the connecting portion 120 and the second plate portion 130, but also the first plate portion 110 may have a flexible material.
[0019] The second plate portion 130 has a pressure point portion 140 that comes into close contact with the lower back of the person sitting in the functional health chair 100. For example, the pressure point portion 140 is formed in a central area of the second plate portion 130 and provides the function of applying pressure and support to the lower back of the person sitting. The pressure point portion 140 can be formed integrally with the second plate portion 130.
[0020] In one embodiment of the present invention, the lower end of the acupressure portion 140 is connected to the connecting portion 120, and the upper and side ends of the acupressure portion 140 are separated from the second plate portion 130. Furthermore, the acupressure portion 140 protrudes relative to the surface of the second plate portion 130. Due to these structural features, when a person sits on the functional health chair 100 and leans their back against the second plate portion 130, the second plate portion 130 and the acupressure portion 140 deform elastically, although the second plate portion 130 and the acupressure portion 140 may have different restoring forces. Because the acupressure portion 140 protrudes forward of the second plate portion 130, when a person leans their back against the second plate portion 130, a stronger force acts on the lower back, which is the part of the body in close contact with the acupressure portion 140, than on the remaining parts of the body in close contact with the second plate portion 130. The acupressure portion 140 provides strong pressure and force, maximizing the acupressure effect on the sitter's lumbar spine. In one embodiment, when a sitter sits on the functional health chair 100 and leans their body against the rear, the front of the first plate portion 110 moves downward due to the sitter's weight, and the acupressure portion 140 can provide an acupressure effect to the sitter's lower back with a stronger restoring force than other parts of the second plate portion 130.
[0021] The acupressure section 140 includes a number of protrusions 145 for stimulating the lower back area of the sitter when the sitter is seated in the functional health chair 100. The material of these protrusions 145 may vary. The protrusions 145 may be arranged at predetermined intervals along the longitudinal direction of the second plate portion 130, or they may be arranged symmetrically. Such protrusions 145 play a role in further enhancing the acupressure effect on the lumbar region of the functional health chair 100.
[0022] The protrusions 145 in Figure 1 shall be positioned according to Figure 2, which shows the locations of acupuncture points on the buttocks and lower back of the human body according to traditional Chinese medicine. This is the most important requirement of the present invention. When a person sits in the functional health chair (100) and presses their body against the backrest, the acupressure area (140) also has elasticity and can deform to conform to the waist area of the functional health chair. In one embodiment, the acupressure portion (140) can provide an acupressure effect to the sitter's lower back with a stronger restorative force than other parts of the second plate portion (130). The protrusion (145) formed on the acupressure portion (140) can maximize the acupressure effect. The functional health chair (100), in which the first plate portion (110), the second plate portion (130), the connecting portion (120), and the acupressure portion (140) are integrally formed, can provide an acupressure effect to the sitter based on the elastic force of the acupressure portion (140), enabling the functional health chair to allow the sitter to sit in the correct posture. Furthermore, when a sitter sits on the functional health chair (100), an effect can occur in which the second plate portion (130) is separated into left and right sides with respect to the acupressure portion (140), thereby enabling the second plate portion (130) to effectively support the sitter's back. Potential for industrial use
[0023] The functional health chair 100 described above can efficiently provide acupressure effects to the lumbar region through the acupressure section 140, which is integrally formed with the first plate section 110 and the second plate section 130, without the need for complex structures or hinge mechanisms. By integrally forming the acupressure section 140 with other components, the manufacturing process for the functional health chair 100 is simplified, and the costs incurred in manufacturing the functional health chair 100 can be reduced. Furthermore, the functional health chair 100 equipped with the acupressure section 140 can provide the effect of preventing lumbar spine deformation, fatigue, and lower back pain when the user sits in the chair. The user can sit comfortably in the functional health chair 100 for long periods of time without lumbar pain, feeling at ease and maintaining correct posture. [Explanation of Symbols]
