Description

Posture correction exercise equipment, base components, and treatment devices

[0001] This invention relates to a technology that can be used for posture correction, primarily targeting the spine (backbone), including the cervical vertebrae, and includes the following four inventions: [First Invention] Posture correction exercise device equipped with a main body length extension mechanism [Second Invention] Base member for posture correction exercise device [Third Invention] Posture correction exercise device equipped with an angle adjustment mechanism [Fourth Invention] Posture correction treatment device. These first, second, third, and fourth inventions can be adopted separately in a product (product invention), or any two, three, or even four of them can be combined and adopted, and the combination of each invention is not limited. Furthermore, the terms such as "treatment" used in this specification do not mean medical or therapeutic acts, but rather encompass a wide range of acts that can have some effect on the human body without limitation, and are interpreted to include personal acts that do not require qualifications, such as massage and relaxation.

[0002] The spine (the bones that make up the backbone), which supports the center of the human body, is formed by stacking multiple vertebrae like building blocks with intervertebral discs in between, and forms the vertebral column that extends from the neck to the buttocks. Inside the spine, there is a spinal canal that extends along its entire length, connecting the spaces between the vertebral bodies and vertebral arches that make up the spine, and the spinal cord passes through this canal.

[0003] The spine not only plays a vital role in supporting the trunk and moving the body, but also protects the spinal cord of the central nervous system, which passes through the spinal canal. Furthermore, nerve roots that branch off from the spinal cord extend from between each vertebra that makes up the spine, reaching various parts of the body, including the limbs, as peripheral nerves.

[0004] Therefore, if there is a distortion in the spine, it will not only greatly impede body movement, but also cause symptoms such as pain and numbness in various parts of the body due to compression on nerves and the like. Of course, there is no problem if the spine is normal, but spinal distortion occurs congenitally or acquiredly. In order to alleviate or eliminate symptoms occurring in the human body due to spinal distortion, it is necessary to improve the spinal distortion.

[0005] As one of treatment methods for improving spinal distortion, traction therapy using an apparatus as described in Patent Document 1 or the like is known. However, traction therapy requires a very large-scale apparatus and professional knowledge for control and operation. Therefore, patients with physical abnormalities themselves have to go to hospitals or the like where special traction devices are installed, which not only imposes a heavy burden, but also makes it difficult to receive frequent traction treatments, so it has been difficult to receive optimal treatments.

[0006] In view of such problems, the present inventor previously proposed a postural correction exercise apparatus with a novel structure in Japanese Patent No. 3995702 (Patent Document 2), which can obtain an improvement effect on spinal distortion and the like without using a large-scale apparatus.

[0007] The postural correction exercise apparatus described in Patent Document 2 is an epoch-making device that is very simple and easy to handle compared to conventional large-scale traction devices that are unmanageable for individuals, and by using the apparatus, it is possible to correct distortion of the spine and also expect the effect of strengthening muscles that support the spine, thereby it can also be expected to fundamentally reduce the burden on the spine. In fact, when the postural correction exercise apparatus according to the invention described in Patent Document 2 was planned and started to be sold as a product, very good responses have been obtained, to the extent that similar counterfeit products are sold in domestic and overseas markets including online sales. In addition, at the industrial exchange exhibition held at Tokyo Big Sight this fiscal year (FY2025), which was exhibited with the cooperation of the chamber of commerce and industry, such a great response was obtained that crowds gathered around the demonstrations and explanations. In particular, most of the visitors who actually experienced the device showed reactions that could not hide their surprise at the effect, and there have been so many inquiries afterwards that it is difficult to handle them. Furthermore, in consideration of the environment where stiff shoulders and the like tend to become chronic due to the nature of work, the current situation is that the invention has also developed into large-volume contract sales.

[0008] As described above, the posture-correcting exercise device developed by the inventor has already received a great response and evaluation in the market. However, dealing with similar counterfeit products is extremely difficult, and legal action is particularly challenging in the case of online sales. In light of this situation, the inventor conducted further research and development with the aim of enabling more patients to use the posture-correcting exercise device he developed appropriately and to provide an even better, improved product, which led to the completion of this invention.

[0009] JP-A-6-38996 Patent No. 3995702

[0010] Herein, the present invention has been made against the background of the circumstances described above, and its objective is to newly develop a posture correction exercise device disclosed in Patent Document 2 above, which has received a good response in the market, with the aim of further improving its performance and effectiveness. Specifically, the objective is to provide four novel devices, components, or apparatuses, as described below: the first, second, third, and fourth inventions, which offer greater potential for correcting spinal curvature. [First Invention] Posture correction exercise device equipped with a main body length extension mechanism [Second Invention] Base component for posture correction exercise device [Third Invention] Posture correction exercise device equipped with an angle adjustment mechanism [Fourth Invention] Posture correction treatment device

[0011] The present invention includes the following embodiments. The [First Invention] includes the embodiments of [Aspects A-1 to A-6] below. The [Second Invention] includes the embodiments of [Aspects B-1 to B-3] below. The [Third Invention] includes the embodiments of [Aspects C-1 to C-2] below. The [Fourth Invention] includes the embodiments of [Aspects D-1 to D-8] below. It should be noted that none of the inventions are limited in interpretation by the embodiments described below. That is, preferred embodiments for understanding the present invention are described below, but the embodiments described below (including embodiments of different inventions) are described as examples and can be combined with each other as appropriate. Furthermore, the multiple components described in each embodiment can be recognized and adopted as independently as possible, and can be combined with any component described in another embodiment as appropriate. In addition, although specific embodiments are not listed one by one, various changes, modifications, improvements, etc. can be made to each embodiment and each component of the present invention based on the knowledge of those skilled in the art, and the results obtained therefrom are also included within the scope of the present invention as long as they do not deviate from the spirit of the present invention.

[0012] [First Invention] Posture Correction Exercise Device Equipped with a Body Length Extension Mechanism [Aspect A-1] A posture correction exercise device having a chin rest portion on which the user rests their chin and a support portion that supports the user's load applied to the chin rest portion, provided at both ends, wherein the reaction force of the user's load can be applied from the chin rest portion to the user's chin and then applied to the user's spine, and the posture correction exercise device is equipped with a body length extension mechanism that can be extended and retracted while the user's chin is resting on the chin rest portion, thereby changing the distance between the support portion and the chin rest portion.

[0013] The posture correction exercise device according to this embodiment employs a mechanism for extending and retracting the length of the main body, which makes it easy to diversify the treatment methods for patients. Specifically, the posture correction exercise device according to this embodiment is set up so that it stands upright when the end face on the support part is placed on a mounting surface (support surface) such as a table, and the user applies a load using their own body weight to the chin placed on the chin rest. The reaction force of the user's load on the mounting surface is exerted as a tensile force from the user's chin to the spine, such as the cervical vertebrae, thereby exerting a traction effect. At that time, the relative height position of the chin rest to the height position of the user's chin affects the user's posture during use, and consequently the curvature and inclination of the spine, as well as the direction of the load applied to the spine and the magnitude of the load applied to the spine.

[0014] In this embodiment, the posture correction exercise device does not require the user to change or adjust the height of the chair they sit on, the floor they stand on, or the height of the table or other surface on which the posture correction exercise device is placed. Instead, the distance between the support part and the chin rest part can be appropriately adjusted using the telescopic mechanism, making it easy to change or adjust the user's posture, the curvature and inclination of the spine during treatment. Furthermore, it becomes possible to vary and adjust the direction and magnitude of the load applied to the spine. Therefore, even if the patient's physique or the treatment content differs, it becomes possible to easily adapt and achieve an appropriate treatment state by using the telescopic mechanism without having to expend the effort of adjusting the height of the chair or table.

[0015] [Aspect A-2] The posture correction exercise device according to [Aspect A-1], further having an integral support column portion extending from the chin rest portion toward the support portion, wherein the main body length extension mechanism is provided on the support column portion.

[0016] In the posture correction exercise device according to this embodiment, since an extendable mechanism is incorporated into the support column, it becomes possible to handle the posture correction exercise device, including the extendable mechanism, as a single unit, and its compact size makes it easy to move and carry.

[0017] [Aspect A-3] The posture correction exercise device according to [Aspect A-1] or [Aspect A-2], wherein the support portion is tiltably supported in contact with the support portion, and a non-slip surface is provided on the surface that is supported in contact with the support portion.

[0018] In the posture correction exercise device according to this embodiment, when the support is placed on a flat mounting surface and the direction and location of the traction force applied to the spine, including the cervical vertebrae, is adjusted by tilting it, for example as shown in the usage example in Patent Document 2, it is possible to prevent the support from slipping due to the action of the load component force applied in the direction of inclination relative to the horizontal mounting surface. As a result, it becomes possible to apply a large load in an inclined state, and since accidental slippage during use is prevented, more stable treatment can be performed with a large load.

[0019] [Aspect A-4] The base end where the support portion is located has a semicircular cross-section, with a straight section on the side near the user and an arc section on the side far from the user, and both ends of the straight section are connected to both ends of the arc section by connecting portions with a smaller radius of curvature than the arc section, resulting in an overall outer circumference shape that is smooth and without corners, and the end face on the support portion side has a central portion and an outer circumference portion, the outer circumference portion is positioned to surround the entire circumference of the flat central portion, and the outer circumference portion curves upward from the outer circumference end of the central portion without corners and rises smoothly to connect to the outer circumference surface on the base end, as described in any of [Aspect A-1], [Aspect A-2], or [Aspect A-3].

[0020] The posture-correcting exercise device according to this embodiment is formed with a smooth, roughly semi-circular shape overall, with the side facing the user being flat and the side far from the user being rounded in the circumferential direction. Therefore, for example, as shown in the usage example in Figure 4-10 of Patent Document 2, when the device is set upright with the end face on the support part placed on a support surface such as a table, and the user rests their chin on the chin rest and tilts it while applying load, unlike the roughly flat shape similar to a kickboard described in Patent Document 2, it becomes easier for the user to hold the posture-correcting exercise device with both hands, enabling stable exercise.

[0021] Furthermore, the flattened front side ensures stability of the posture correction exercise device when tucking the chin and applying a large load, while the arc shape of the far side makes it easy to tilt the posture correction exercise device forward (away from the user) while adding appropriate inclines to the left and right. This allows for the application of traction forces in various directions to the spine, including the cervical vertebrae, while smoothly changing direction.

[0022] In particular, the central part of the base has a nearly flat surface perpendicular to the central axis, making it easy to perceive the upright position of the reference posture correction exercise device and allowing it to be stably maintained in this upright position. On the other hand, the outer circumference has a smoothly curving shape that rises all the way around, allowing it to smoothly tilt and transition from the upright position to various tilting directions. This makes it possible to change the traction force applied to the user in various directions without abrupt changes, enabling efficient and continuous treatment using traction force in various directions.

[0023] [Aspect A-5] A posture correction exercise device according to any of [Aspect A-1], [Aspect A-2], [Aspect A-3], or [Aspect A-4], wherein the device has a divided structure divided into a chin rest side having the chin rest portion and a support side having the support portion, and is provided with a connecting portion that connects the chin rest side and the support side to each other, and a drive source that drives the main body length extension mechanism is provided on the support side.

[0024] In the posture correction exercise device according to this embodiment, by providing the drive source for the main body length extension mechanism on the support side, the structure of the divided body on the chin rest side can be simplified, and the weight of the pump or motor used as the drive source can be used to lower the center of gravity of the posture correction exercise device. As a result, the stability of the device can be improved during treatments that include tilting of the posture correction exercise device, making treatments easier and more efficient. Furthermore, by providing the drive source, which tends to have a complex structure and many moving parts, on the divided body on the support side, it can be separated from the chin rest side, which is less prone to breakage, and there is a practical advantage in that it is easier to replace or repair only the support side.

[0025] [Aspect A-6] A posture correction exercise device according to any of [Aspect A-1], [Aspect A-2], [Aspect A-3], [Aspect A-4], or [Aspect A-5], wherein the device has a divided structure divided into a chin rest side having the chin rest portion and a support side having the support portion, and is provided with a connecting portion that connects the chin rest side and the support side, and the main body length extension mechanism is provided on the support side.

[0026] In the posture correction exercise device according to this embodiment, the structure of the divided part on the chin rest side can be made extremely simple, and for example, it becomes possible to easily replace only the divided part on the chin rest side. That is, in the posture correction exercise device according to this embodiment, for example, the connecting part can be made separable, and by making it possible to divide it into multiple small parts, handling, storage, movement and carrying can be made easier. In addition, in this embodiment, since the main body length extension mechanism is provided on the support part side, the chin rest side can be made to be easily attached to and detached from the support part side, so that the chin rest side can be used as the main body side and only the main body side can be used independently (i.e., without the support part side). In short, the connecting part on the main body side to the support part side may also be provided with a support surface structure that can be supported by a mounting surface such as a table and load can be applied, similar to the support part side, thereby providing an option to perform the desired posture correction exercise using only the main body side without using the main body length extension mechanism.

[0027] Furthermore, in the posture correction exercise device according to this embodiment, the chin rest side and the support side can be repeatedly connected and separated from each other, making it possible to replace only one of them as needed, and allowing for low-cost solutions if only one side is damaged. Specifically, for example, the chin rest side is more prone to soiling because it comes into contact with the human chin compared to the support side where the drive source for the telescopic mechanism is located, so early replacement may be desired, or the support side may be desired to be replaced only when the drive source fails. Alternatively, when one posture correction exercise device is shared by multiple people, it is possible to prepare only the chin rest side, which comes into contact with each person's body (skin), and share the support side.

[0028] Furthermore, when multiple people share a posture correction exercise device, it is possible to prepare multiple devices with different sizes (lengths) for the chin rest side, or conversely, with different amounts of elasticity for the support side, depending on each individual's physique and the type of treatment they are receiving. This allows for a wide range of treatment options to be offered with greater flexibility, enabling the provision of appropriate treatment for each individual, while minimizing the overall equipment burden and ensuring efficiency.

[0029] Furthermore, even if a user already owns a posture correction exercise device that does not have a length-extending mechanism, the support part may be provided in a manner that allows it to be connected to the said device, thereby enabling the efficient use of conventional posture correction exercise devices.

[0030] Furthermore, in this embodiment, it is preferable that the divided structure between the chin rest side and the support side can be repeatedly separated and connected as needed, and in that case, various divided / connected structures can be adopted, and the specific structure is not limited. However, it is also possible to connect the chin rest side and the support side in a way that makes separation impossible by adhesive or the like, depending on the requirements. In addition, in such a divided structure, for example, a structure can be adopted that allows the chin rest side and the support side to be preferably connected integrally while suppressing mutual bending and expansion / contraction (the expansion / contraction function itself is provided by the support side), and specifically, they can be connected by various structures such as fitting, screw fastening, pin connection, and interlocking. Note that since there is almost no tensile force acting between the chin rest side and the support side during the procedure, the connection between them may be in a state where they can be pulled out (by fitting, etc.). Also, since bending force may act during tilting, it is preferable that the connection is in a state where bending and curvature are restricted or prevented.

[0031] In each of the above-described embodiments, the length extension mechanism of the main body is preferably configured to include at least one of a pneumatic actuator and an electric actuator.

[0032] In such posture-correcting exercise equipment, the telescopic mechanism can be implemented relatively easily and inexpensively. For example, commercially available pneumatic or electric actuators that constitute the telescopic mechanism can be used and incorporated. Furthermore, since there is no need to manually operate the telescopic mechanism (for example, by rotating a handle to activate the screw feed mechanism), excellent operability is achieved, and maintenance is easier compared to other actuators such as hydraulic types. It is desirable that the pneumatic actuator be equipped with a pneumatic pump and supply / discharge valves, and electric pumps can be used as the pneumatic pump. It is also preferable that the electric actuator utilizes an electric motor. Moreover, the electric actuator may be structured to drive a known telescopic mechanism, such as a pantograph mechanism or a rack and pinion mechanism, with an electric motor. The main body length telescopic mechanism itself is equipped with a guide mechanism that linearly defines the direction of movement, and it is also possible to use known guide mechanisms such as telescopic rods or guide rods that allow linear reciprocating movement and stably set the direction of telescopic movement in combination with the above-mentioned driving means.

[0033] [Second Invention] Base Member for Posture Correction Exercise Equipment [Aspect B-1] A base member for posture correction exercise equipment, which is used in combination with a posture correction exercise equipment that has a chin rest portion on which the user rests their chin and a support portion on which the user's load is supported applied to the chin rest portion, and which is used in combination with a posture correction exercise equipment that can apply the reaction force of the user's load from the chin rest portion to the user's chin and then to the user's spine, and which has a mounting surface on which the posture correction exercise equipment is placed so as to tiltably contact and support the support portion, and the base member is equipped with a base height extension mechanism that changes the height dimension when the posture correction exercise equipment is placed on it.

[0034] In the base member for the posture correction exercise device according to this embodiment, the base member is equipped with a height adjustment mechanism, which makes it possible to change the distance from the mounting surface, such as a table, to the chin rest, regardless of the size or shape of the posture correction exercise device, thereby accommodating a variety of posture correction exercise devices. As a result, various effects, such as diversification of treatment methods for patients, can be achieved, similar to the posture correction exercise device according to the [First Invention].

[0035] Furthermore, with the base member according to the present invention, for example, by purchasing only the base member anew, it is possible to use the posture correction exercise device that the patient already owns (posture correction exercise device) as the main body of the exercise device. The amount of expansion and contraction and size of the base member can be varied according to the patient, and for example, the base member can be shared by multiple users. In that case, by preparing the posture correction exercise device main body separately according to the physique and exercise style of each user, appropriate exercise can be efficiently achieved for each user.

[0036] [Aspect B-2] The base member for a posture-correcting exercise device according to [Aspect B-1], wherein the base member is provided with a non-slip surface on at least one of the mounting surface on which the posture-correcting exercise device is placed and the bottom surface that contacts the mounting surface such as a table.

[0037] In the base member according to this embodiment, the same effects and benefits as those of the posture-correcting exercise device according to [Embodiment A-3] can be effectively achieved.

[0038] [Aspect B-3] A base member for a posture-correcting exercise device according to [Aspect B-1] or [Aspect B-2], wherein the base height extension mechanism comprises at least one of a pneumatic actuator and an electric actuator.

[0039] In the base member according to this embodiment, the same effects and benefits as those of the posture-correcting exercise device according to [Embodiment A-6] can be effectively achieved.

[0040] [Third Invention] Posture Correction Exercise Device with Angle Adjustment Mechanism [Aspect C-1] A posture correction exercise device having a chin rest on which the user rests their chin and a support part that supports the user's load applied to the chin rest, provided at both ends, wherein the reaction force of the user's load can be applied from the chin rest to the user's chin and then to the user's spine, wherein an angle adjustment mechanism that can be bent at an intermediate position between the support part and the chin rest is provided, and the direction of the chin rest relative to the support part can be changed by bending at the intermediate position.

[0041] According to the posture correction exercise device of this embodiment, the angle adjustment mechanism allows for more appropriate adjustment of, for example, the position and direction of the chin rest, according to the patient's condition, physique, and usage. By adjusting the direction and angle of the chin rest, it becomes possible to diversify the treatment methods applied to the patient. Furthermore, by adjusting the direction and angle of the chin rest, it becomes easier to efficiently apply, adjust, or increase the force acting on the patient.

[0042] Furthermore, in the posture correction exercise device according to this embodiment, the allowable bending angle of the angle adjustment mechanism provided at the intermediate position may be set to be permissible in one direction around a single pivot axis, or it may be set to allow swinging around axes extending in multiple directions that are different from each other, such as two directions around two pivot axes that are orthogonal to each other, or it may be set to allow swinging in multiple directions, like a flexible joint. In addition, it is possible to use the device in a state where bending is freely permitted at the angle adjustment mechanism provided at the intermediate position, and in that case, with the support part fixed to a base such as a mounting table so as to be unable to tilt, it is possible to perform treatments such as traction by allowing changes in the direction and angle of the chin rest through the bending operation of the angle adjustment mechanism.

[0043] [Aspect C-2] An exercise device for correcting posture, comprising the angle adjustment mechanism described in [Aspect C-1], wherein the angle adjustment mechanism is further provided with an angle setting mechanism that fixes the bending angle at an intermediate position between the support portion and the chin rest portion.

[0044] In the posture correction exercise device according to this aspect, by adjusting and setting the bending angle at an intermediate position in the height direction, when performing treatment or the like by tilting at the lower end of the support part, the direction of the chin rest can be appropriately adjusted according to the user, posture, etc., so that it is possible to reduce the user's pain and set the angle such that traction force and the like are exerted more efficiently.

[0045] [Fourth Invention] A treatment device for posture correction [Aspect D-1] A posture correction treatment device used for treatments such as traction and massage that apply an external force to a patient's spine, wherein a support seat is provided at a position facing the patient's jaw, the support seat protrudes toward the patient's jaw, a chin rest on which the patient's jaw is placed is provided at the protruding distal end portion, and the posture correction treatment device comprises an auxiliary posture correction mechanism capable of causing a reaction force of a load applied from the patient's jaw to act on the patient's jaw from the chin rest and thereby acting on the patient's spine.

[0046] According to the posture correction treatment device according to this aspect, in various posture correction treatment devices such as various conventionally known traction devices and treatment beds, by applying a load reaction force to the jaw of the patient during treatment, it becomes possible to apply a corrective external force in a direction that was difficult to achieve with conventional treatment devices, for example. Furthermore, compared to using only the conventional posture correction exercise device as described in Patent Document 2 alone on a placement surface such as a desk, applying the device to a posture correction treatment device according to the present aspect makes it possible to combine the treatment force applied to the user during treatment using the treatment device and the posture to exert a combined effect, so that acting forces in various directions, simultaneous acting forces on a plurality of locations, or greater acting forces that were difficult to achieve when used alone can be applied to the user in various modes as needed, enabling more efficient treatment.

[0047] [Aspect D-2] The posture correction treatment device according to [Aspect D-1], wherein the auxiliary posture correction mechanism is tiltable at a proximal end portion protruding toward the patient's jaw.

[0048] In the posture correction treatment device according to this embodiment, the direction and magnitude of the treatment force exerted on the patient's jaw by the posture correction auxiliary mechanism can be adjusted and set by tilting the posture correction auxiliary mechanism, thereby allowing an external treatment force to act on the patient (user) more efficiently, and improving the exercise effect (including effects such as stretching and muscle strength enhancement) exerted on the patient.

[0049] Note that, similar to the present embodiment, any of the aspects described below relating to D-3, D-4, and D-5 can also allow the posture correction auxiliary mechanism to more efficiently exert an external treatment force on the patient's jaw and improve the exercise effect, so that an improvement in treatment effect can be expected.

[0050] [Aspect D-3] The posture correction treatment device according to [Aspect D-1] or [Aspect D-2], wherein the posture correction auxiliary mechanism includes a protruding height extension / retraction mechanism that changes a distance in a protruding direction from the support seat to the jaw rest portion.

[0051] Note that, in the posture correction treatment device according to this embodiment, the various functional effects as described above in [Aspect A-1], [Aspect B-1], and the like can also be obtained equally.

[0052] [Aspect D-4] The posture correction treatment device according to [Aspect D-3], wherein the protruding height extension / retraction mechanism is configured to include at least one of a pneumatic actuator and an electric actuator.

[0053] Note that, in the posture correction treatment device according to this embodiment, the various functional effects as described above in [Aspect A-6], [Aspect B-3], and the like can also be obtained equally.

[0054] [Aspect D-5] The posture correction treatment device according to any one of [Aspect D-1] to [Aspect D-4], wherein a direction of the jaw rest portion in the posture correction auxiliary mechanism is adjustable.

[0055] Furthermore, in the posture correction device according to this embodiment, the various effects and benefits described above in [Embodiment C-1], etc., can also be obtained in an equivalent manner. In addition, depending on the configuration of the adjustment mechanism for the direction of the chin rest, the various effects and benefits described above in [Embodiment C-2], etc., can also be obtained in an equivalent manner.

[0056] [Aspect D-6] A posture correction treatment device according to any one of [Aspect D-1] to [Aspect D-5], comprising a seat on which a patient sits, a traction mechanism that applies an upward traction force to the head of a seated patient, a support seat positioned diagonally forward and inclined downward with respect to the head of the seated patient, and the posture correction auxiliary mechanism provided so as to protrude from the support seat toward the chin of the patient.

[0057] This embodiment [Embodiment D-6] and the following embodiments (Embodiments D-7, D-8) are exemplary embodiments illustrating preferred applications of the posture correction auxiliary mechanism according to the present invention in a specific posture correction treatment device. In this embodiment, when applying an upward traction force to the head of a seated patient (user), for example, by tilting it diagonally forward, the forward component of such traction force is utilized, making it possible to obtain a more efficient force acting on the vertebrae, etc., by the posture correction auxiliary mechanism, by utilizing not only the patient's weight but also the traction force. It should be noted that the posture correction treatment device according to the present invention is not limited to these embodiments D-6, D-7, and D-8, but these embodiments can be suitably adopted as a treatment device equipped with the posture correction auxiliary mechanism according to the present invention.

[0058] [Aspect D-7] A posture correction treatment device according to any one of [Aspect D-1] to [Aspect D-5], comprising a massage bed for performing treatment on a prone patient lying face down, and the posture correction auxiliary mechanism provided to protrude from below toward the chin of the prone patient.

[0059] In this embodiment, by utilizing the weight of the upper body, including the head, of the prone patient (user), it becomes possible to more efficiently obtain the force acting on the vertebrae, etc., by the posture correction assisting mechanism. Furthermore, when applying a treatment force by pressing from the back to the prone patient, it becomes possible to more efficiently obtain the force acting on the vertebrae, etc., by the posture correction assisting mechanism by utilizing this treatment force as well.

[0060] [Aspect D-8] A posture correction treatment device according to any one of [Aspect D-1] to [Aspect D-5], comprising a chest support portion that supports the forward-leaning chest of a seated patient, and a head support portion located above the chest support portion that supports the area around the patient's face, wherein the posture correction auxiliary mechanism is provided so as to protrude toward the chin of the patient located below the head support portion.

[0061] In this embodiment, the patient's (user's) body weight can be utilized more efficiently to obtain a more efficient force acting on the vertebrae, etc., by the posture correction assist mechanism. For example, in a seated position, the weight of the patient's head is also supported by the spine, but by tilting the patient forward sufficiently, the burden of spinal support on the head's weight can be reduced, making it possible to utilize this more efficiently as a force acting on the vertebrae, etc., by the posture correction assist mechanism.

[0062] According to each of the first to fourth inventions, the following effects can be expected.

[0063] The "posture-correcting exercise device equipped with a main body length extension mechanism" according to the [First Invention], compared to the posture-correcting exercise device according to the previous invention described in Patent Document 2, is newly equipped with a main body length extension mechanism, which allows the user to change the distance between the support part and the chin rest while the user's chin is resting on the chin rest. This makes it easier to easily achieve more effective treatments (including exercises) that were difficult to achieve with the posture-correcting exercise device alone.

[0064] The "base member for posture correction exercise equipment" according to the [second invention] can be used in combination with, for example, the posture correction exercise equipment according to the previous invention described in Patent Document 2, to realize an expandable and contractible function. This allows the user to change the distance between the support part and the chin rest while the user rests their chin on the chin rest. As a result, it becomes easy to achieve more effective treatments (including exercises) and appropriate treatments according to the user's physique, which were difficult to achieve with the posture correction exercise equipment alone.

[0065] The "posture-correcting exercise device equipped with an angle adjustment mechanism" according to the [Third Invention], compared to the posture-correcting exercise device according to the previous invention described in Patent Document 2, newly employs an angle adjustment mechanism, making it possible to more appropriately adjust and set, for example, the position and direction of the chin rest, according to the patient's condition, physique, usage, etc. This is expected to lead to diversification of treatment methods for patients and increased efficiency.

[0066] In the "posture correction treatment device" related to the [fourth invention], by adopting a new posture correction auxiliary mechanism in the posture correction treatment device, it becomes possible to perform treatments that were difficult to achieve with conventional posture correction treatment devices.

[0068] Embodiments of the present invention are described in Figures 1 to 12. Considering the prior art described in Patent Document 2, etc., the first, second, third, and fourth inventions described in each of the above embodiments can all be sufficiently understood by a person skilled in the art to the extent that they can implement the invention, even from the disclosures shown in Figures 1 to 12 alone. Furthermore, considering the above description in this specification, the effects and advantages of the present invention will also be understood by a person skilled in the art, but for the sake of clarity, an explanation is provided below.

[0069] Figures 1 and 2 show a posture-correcting exercise device 10 as a first embodiment of the present invention.

[0070] The posture-correcting exercise device 10 has a longitudinal shape that extends for a predetermined length in the central axis direction, which is the vertical direction in Figure 1. It has a chin rest portion 14, which is the upper surface on which the user rests their chin, and a support portion 18, which is the lower surface that supports the user's load on the chin rest portion 14 when the posture-correcting exercise device 10 is placed on a surface such as a table during use. These support portions are provided at both ends in the longitudinal direction (vertical direction in Figure 1).

[0071] The chin rest portion 14 has a flat surface shape that extends perpendicular to the central axis as a whole. A chin rest recess 20 is formed approximately in the center of the chin rest portion 14 so that the user can easily recognize the position where to rest their chin and so that the chin can be held stably.

[0072] The posture correction exercise device 10 of this embodiment is a posture correction exercise device that utilizes the user's own weight to apply a load input from the chin rest recess 20, and the reaction force applied from the mounting surface such as a table to the support part 18 is applied from the chin rest part 14 (chin rest recess 20) to the user's chin and applied to the user's spine. The device is equipped with a telescopic mechanism 22 that is extendable and retractable while the user's chin is resting on the chin rest part 14, and changes the distance between the support part 18 and the chin rest part 14.

[0073] The posture correction exercise device 10 of this embodiment has an integrated support column portion 21 that extends from the chin rest portion 14 toward the support portion 18 (in short, it is not easily separated or divided unintentionally and is not damaged by input). In this embodiment, the entire length between the chin rest portion 14 and the support portion 18 is made up of a support column portion 21, which extends linearly in the vertical direction with a substantially constant outer peripheral surface shape (cross-sectional outer peripheral surface shape) along its entire length, and a main body length extension mechanism 22 is provided at the middle of the height direction (vertical length direction) of this support column portion 21.

[0074] Furthermore, the support portion 18 is tiltably supported in contact with a mounting surface such as a table, and a non-slip surface is provided on the surface of the support portion 18 that is supported in contact with the mounting surface. In this embodiment, as such a non-slip surface, a high-friction material layer 24, such as rubber or elastomer, is formed by coating or the like so as to cover substantially the entire surface of the support portion 18, as shown in the enlarged vertical cross section in Figure 2(a). However, the non-slip surface is not limited to this embodiment, and can be appropriately formed by, for example, forming the surface of the support portion 18 itself with a high-friction material, partially fixing a high-friction material to the surface of the support portion 18, or forming a large number of minute protrusions.

[0075] Furthermore, at least the lower end portion of the support column 21 that reaches the support portion 18 has a semicircular cross-section, as shown in Figure 2(b), with a straight section 26 on the side closer to the user and an arc section 28 on the side further away from the user. Both ends of the straight section 26 are connected to both ends of the arc section 28 by connecting portions 30 having a smaller radius of curvature than the arc section 28, resulting in an overall outer circumference shape that is smooth and without corners, resembling a kamaboko (fish cake).

[0076] In this embodiment, the support column portion 21 has a surface shape that resembles a kamaboko (fish cake) along its entire length.

[0077] Furthermore, the support portion 18, which is the lower end face of the support column portion 21, has an outer circumference shape in an axial view that is approximately equal to the cross-sectional shape of the support column portion 21, and has a central portion 34 and an outer circumference portion 36. The outer circumference portion 36 is provided so as to surround the entire circumference of the flat central portion 34, which extends perpendicular to the central axis of the support column portion 21. The outer circumference portion 36 curves upward smoothly from the outer circumference end of the central portion 34 without any corners and connects to the outer circumference surface 38 of the support column portion 21. In particular, in this embodiment, in all longitudinal sections around the central axis, the outer circumference portion has a curved shape that is convex outward, and the entire structure, including the connection points with the central portion 34 and the outer circumference surface 38, is continuous and smoothly connected by a common tangent. Note that such a curved shape does not need to have a constant radius of curvature, but in this embodiment, it has an arc-shaped cross-section with a substantially constant radius of curvature over the entire length connecting the central portion 34 and the outer circumference surface 38.

[0078] The outer edge of the support portion 18, which connects to the outer surface of the support column portion 21, has such a smooth curved cross-sectional shape. This allows the support column portion 21, and thus the posture correction exercise device 10, to be set in a vertical position with a sense of control when the support portion 18 is placed on a flat surface with the support column portion 21 standing almost vertically. Furthermore, it is possible to tilt (incline) it smoothly and easily from that position, and to change the angle of inclination smoothly.

[0079] Furthermore, in the posture correction exercise device 10 of this embodiment, the support column portion 21 is divided lengthwise in the middle portion in the height direction into a chin rest portion 14 side having a chin rest recess 20 and a support portion 18 side. The upper divided support column portion 40 having the chin rest portion 14 and the lower divided support column portion 42 having the support portion 18 are connected to each other at a connecting portion 46.

[0080] The upper and lower divided support sections 40 and 42 only need to have sufficient strength to maintain a certain shape when subjected to input, and are not limited by material. For example, they can be made of synthetic resin, wood, or light metal, and may have a hollow structure, or be made of foam material for weight reduction, or have a surface to improve the feel and texture of the surface. The connecting section 44 may connect the upper and lower divided support sections 40 and 42 in an inseparable manner (cannot be separated), but may also be connected in a separable or detachable manner.

[0081] In particular, in this embodiment, the connecting portion 44 is provided with a main body length extension mechanism 50 that allows the length dimension of the support column portion 21 to be adjusted, thereby changing the distance between the chin rest portion 14 (upper end surface) and the support portion 18 (lower end surface). In short, the main body length extension mechanism 50 is provided in the middle portion of the support column portion 21 in the longitudinal direction and has an extension function.

[0082] The main body length extension mechanism 50 is not limited to a specific structure, and can be configured, for example, by employing a guide mechanism (such as a guide rod) that guides the upper divided support section 40 and the lower divided support section 42 linearly in the approaching / separating direction while preventing them from tilting relative to each other, and by employing a driving means that drives the upper divided support section 40 and the lower divided support section 42 relatively in the approaching / separating direction.

[0083] More specifically, structures like those shown in the lower (A) and (B) of Figure 1 can be adopted. First, in both (A) and (B), the guide mechanism is configured by inserting a guide rod 54, which is fixed to the other, into a guide hole 52 formed in one of the upper divided support column 40 and the lower divided support column 42 so as to be slidable in the in-and-out direction.

[0084] In (A), a pneumatic actuator 56 is positioned across the space between the upper divided support column 40 and the lower divided support column 42. By controlling the supply and discharge of air pressure from a pneumatic pump 58, which is housed internally in the lower divided support column 42, to the pneumatic actuator 56 using a control switch 62 or the like to operate a pneumatic control valve 60, the driving force from the pneumatic actuator 56 is applied to the space between the upper divided support column 40 and the lower divided support column 42 in an approaching / separating direction, causing the upper divided support column 40 and the lower divided support column 42 to move relative to each other in an approaching / separating direction, making it possible to adjust, set, and maintain the distance between them as appropriate.

[0085] Furthermore, in (B), a male threaded rod 64 protruding downward from the upper split support column 40 is fixed at its upper end and mounted so as not to rotate, while a spur gear-shaped nut member 66, which has a female thread screwed onto the male threaded rod 64 on its inner surface and a gear formed on its outer surface, is mounted on the lower split support column 42 so as not to move in the vertical direction (axial direction of the male threaded rod 64) but so as to be rotatable around the central axis of the male threaded rod 64. In addition, a drive pinion 68 that meshes with a gear formed on the outer surface of the nut member 66 is provided, and an electric motor 70, which acts as an electric actuator to rotate the drive pinion 68, is housed and mounted in the lower split support column 42. Then, by controlling the operation of the electric motor 70 with the control switch 72, the rotation of the nut member 66 drives the male screw rod 64 to screw, thereby moving the upper divided support column 40 and the lower divided support column 42 in the direction of relative approach / separation, making it possible to adjust, set, and maintain the distance between them as appropriate.

[0086] In addition, in the mechanisms illustrated in (A) and (B) above, a locking mechanism for fixing the distance between the upper split support column 40 and the lower split support column 42 may be added separately. For example, in (A), the position can be fixed in an airlock state by blocking the supply and discharge of air to the pneumatic actuator 56, or in (B), the position can be fixed by stopping the power supply to the electric motor and using detent torque.

[0087] Furthermore, as shown in Figures 1 and 2, it is desirable that the expansion and contraction space between the upper divided support section 40 and the lower divided support section 42 be covered on its outer perimeter with an expandable cylindrical cover such as a bellows. However, the specific structure of the main body length expansion and contraction mechanism 50 is not limited to the above description.

[0088] As shown in Figure 1-2, a main body length extension mechanism 50 is provided between the upper divided support section 40 and the lower divided support section 42. In addition, as shown in Figure 3-4, it is also possible to provide the main body length extension mechanism 50 in the lower divided support section 42.

[0089] According to this configuration, the structure of the upper divided support column 40 can be made extremely simple, and the entire mechanism of the main body length extension mechanism 50 can be provided only on the lower divided support column 42 side. Therefore, for example, it becomes possible to replace or share only one of the upper divided support column 40 and the lower divided support column 42.

[0090] Furthermore, as shown in Figure 3-4, a cup-shaped connecting socket 73 is formed at the upper end of the lower divided support column 42, and the lower end of the upper divided support column 40 is fitted into this socket to form a connecting part. This simplifies the structure of the connecting part and prevents tilting, making it possible to connect the upper and lower divided support columns 40 and 42. Moreover, with such a connecting structure, it is not necessary to make the lower end of the upper divided support column 40 tiltable, and a simple end face shape can be used.

[0091] Next, Figure 5 shows a base member 74 as an example of one embodiment of a base member for a posture correction exercise device.

[0092] Such base member 74 can be used in combination with a posture correction exercise device 76. The posture correction exercise device 76 is similar to the posture correction exercise device 10 described above, but does not have an extension mechanism, and it is also possible to use a conventional posture correction exercise device such as the one described in Patent Document 2. However, in this embodiment as well, the posture correction exercise device 10 as shown in the first embodiment described above may be used, which makes it possible to substantially increase the amount of extension and contraction additively.

[0093] In other words, the posture-correcting exercise device 76 is provided with a chin rest 14 on which the user rests their chin, and a support part 18 at both ends that supports the user's load applied to the chin rest 14. This posture-correcting exercise device is capable of applying the reaction force of the user's load from the chin rest 14 to the user's chin and then to the user's spine.

[0094] Furthermore, the base member 74 of this embodiment is used by being placed in a stationary state on a surface such as a table, and is equipped with legs for fixing its position on the surface (for example, multiple support legs, or a flat surface with an anti-slip coating on the entire bottom surface), and on its top surface, it is equipped with a support surface 80 that tiltably contacts and supports the support part 18 when the posture correction exercise device 76 is placed on it. The support surface 80 is, for example, a flat surface, but may also have a recess corresponding to the lower end of the posture correction exercise device 76 so that the lower end of the posture correction exercise device 76 does not move horizontally when the device is tilted. In addition, a high-friction material layer may be formed and attached to the support surface 80 as needed to prevent the lower end surface of the posture correction exercise device 76 from slipping. The high-friction material layer may be provided, for example, on the bottom surface of the base member 74 that is placed on a surface such as a table.

[0095] Furthermore, the base member 74 is equipped with a base height extension mechanism 82, which allows the height dimension to be changed and set. The base height extension mechanism 82 can be constructed with a structure similar to the main body length extension mechanism 50 in the first embodiment. It is also preferable that the base height extension mechanism 82 be designed so that the height dimension can be changed while the posture correction exercise device 76 is placed on it.

[0096] Furthermore, Figure 6-7 shows a posture correction exercise device 90 as an example of one embodiment of a posture correction exercise device equipped with an angle adjustment mechanism.

[0097] The posture correction exercise device 90 of this embodiment has a chin rest 14 on which the user rests their chin, and a support part 18 at both ends that supports the user's load applied to the chin rest 14, so that the reaction force of the user's load can be applied from the chin rest 14 to the user's chin and then to the user's spine.

[0098] Furthermore, the support column connecting the support portion 18 and the chin rest portion 14 is provided with an angle adjustment mechanism 92 that can be bent at an intermediate position in the height direction, and by bending at this intermediate position, the direction of the chin rest portion 14 relative to the support portion 18 can be changed.

[0099] In this embodiment, a jaw rest portion 14 is provided, and a plurality of connecting pieces 94a are formed to protrude downward in a comb-like manner from a member constituting the upper part of the support column portion, and a plurality of connecting pieces 94b are formed to protrude upward in a comb-like manner from a member constituting the lower part of the support column portion, and these are superimposed so as to interlock with each other. A single straight connecting shaft 96 is inserted and mounted through both of these connecting pieces 94a and 94b, and the connecting shaft 96 is bendable around its central axis, thereby forming an angle adjustment mechanism 92.

[0100] Furthermore, a tightening and fixing screw 98 is screwed onto the connecting shaft 98. By tightening the tightening and fixing screw 98, bending due to relative rotation of both connecting pieces 94a and 94b around the connecting shaft 96 is prevented, and they are fixed at a certain bending angle. This allows the direction of the jaw rest 14 relative to the support 18 to be fixedly set. Thus, in this embodiment, an angle setting mechanism is configured in which the bending angle at an intermediate position between the support 18 and the jaw rest 14 is fixedly set by a tightening structure using a tightening and fixing screw 98 that applies a tightening and fixing force to the bending portion.

[0101] In this embodiment of the posture correction exercise device 90, as described above, posture correction exercises may be performed with the angle set by the angle adjustment mechanism 92 fixed to a constant value during use. Alternatively, posture correction exercises may be performed with the angle set by the angle adjustment mechanism 92 not fixed to a constant value, allowing for free angle changes. In this case, instead of making the lower end of the member constituting the lower part of the support column (the member having the connecting piece 94b) a tiltable support, the lower end of the member can be fixed to a mounting surface such as a table in a non-tiltable state, thereby allowing the angle adjustment mechanism 92 to tilt and thus enabling the angle adjustment mechanism 92 to function as a support.

[0102] Furthermore, the angle adjustment mechanism 92 does not need to allow tilting around a single axis; it may also allow tilting around two or more horizontally extending axes. For example, by employing a ball joint or a flexible joint in the angle adjustment mechanism, it may be possible to create a structure that can tilt in any direction.

[0103] Next, Figure 8 shows one embodiment of the "posture correction treatment device equipped with a posture correction auxiliary mechanism" according to the present invention.

[0104] The treatment device 100 of this embodiment is a posture correction treatment device used in treatments such as traction and massage that apply external force to the patient's spine, and has a support seat 102 positioned opposite the patient's jaw. Furthermore, it has a jaw rest 14 that protrudes from the support seat 102 toward the patient's jaw, and the protruding tip portion is provided on which the patient's jaw rests, and a posture correction auxiliary mechanism 104 that can apply the reaction force of the load applied from the patient's jaw to the patient's jaw via the jaw rest 14 and exert it on the patient's spine.

[0105] As such a posture correction auxiliary mechanism 104, for example, the posture correction exercise device 10 shown in the first embodiment can be used. In this embodiment, the support portion 18 of the posture correction exercise device 10 may be fixed in a way that prevents tilting by the support seat 102.

[0106] Of course, the support portion 18 of the posture correction exercise device 10 may be supported by the support seat 102 so as to be tiltable. Alternatively, the posture correction exercise device 90 according to the embodiment shown in Figure 6-7 may be used, and a tiltable angle adjustment mechanism may be provided in the middle portion in the height direction, so that the support portion side is fixed to the support seat 102 so as not to tilt, while the angle adjustment mechanism allows the chin rest side to tilt during treatment.

[0107] Furthermore, by employing the posture correction exercise device 10, a protrusion height adjustment mechanism can be realized that changes the distance in the protruding direction from the support seat 102 to the chin rest. Since a specific structural example of such a protrusion height adjustment mechanism has been described above, redundant descriptions will be omitted.

[0108] In particular, the treatment device 100 illustrated in Figure 8 includes a seat 106 on which the patient sits, a traction mechanism 108 that applies an upward traction force to the head of the seated patient, and a support seat 102 positioned diagonally forward and inclined downward from the head of the seated patient, and the posture correction auxiliary mechanism 104 is provided so as to protrude from the support seat 102 toward the chin of the patient.

[0109] Another embodiment of the treatment device of the present invention is shown in Figure 9-11. This treatment device 110 includes a massage bed 112 for treating a prone patient lying face down, and a posture correction assisting mechanism 114 is provided so as to protrude from below toward the chin of the prone patient. This posture correction assisting mechanism 114 can be configured in the same way as the posture correction assisting mechanism 104 illustrated and described in Figure 8.

[0110] By using such a massage bed 112, it becomes possible to utilize the patient's head weight more efficiently to perform treatment using the posture correction assist mechanism 114.

[0111] In the structural example of the embodiment shown in Figure 9-11, for example, a posture correction exercise device 10 with a structure similar to that shown in Figure 1 can be used as a posture correction auxiliary mechanism 114, and the lower end (support part) of the posture correction auxiliary mechanism 114 is supported so as to be elastically tiltable using an elastic member. That is, by supporting the lower end of the posture correction auxiliary mechanism 114 so as to be elastically tiltable, the lower end is positioned and supported while allowing tilting due to external forces, and the amount of tilt changes automatically according to the magnitude of the external force, and when the external force is removed, it elastically returns to the reference initial angle position before tilting (for example, the direction perpendicular to the mounting surface where the tilt angle is 0).

[0112] In this embodiment in particular, as shown in the figure, the upper region of the bed 112 that supports the upper body is structured to be able to be raised, and the area corresponding to the user's (patient's) head (face) is cut out in an elliptical shape in this upper region. A first tiltable support seat 115, made of a slightly smaller elliptical plate member, is placed in the lower semicircular region of this cut-out elliptical area, and the periphery of the first tiltable support seat 115 is elastically connected to the bed 112 body (in this illustrated embodiment, the mounting base 116 which is detachably fixed to the bed 112) by a first elastic connecting part 117 along approximately half of the inner periphery of the cut-out.

[0113] In addition, in the elliptical cutout area of ​​the bed 112, the upper semicircular area where the first tiltable support seat 115 is not located is fitted with a soft pad 118 with a perforated structure and a hole in the center, which is intended to alleviate the discomfort of patients lying face down on the bed.

[0114] Furthermore, a circular through-hole is formed in the approximate center of the first tiltable support seat 115, and a second tiltable support seat 119, which has a slightly smaller circular plate shape, is positioned within this through-hole. Its outer edge is elastically connected and supported by the first tiltable support seat 115 via the second elastic connecting portion 120. The first and second elastic connecting portions 117 and 120 may be made of connecting members made of, for example, a rubber elastic material.

[0115] The lower end (support portion) of the posture correction assist mechanism 114 is fixed in a non-tiltable manner to the approximate center of the second tiltable support seat 119, and the posture correction assist mechanism 114 is mounted so as to protrude approximately vertically from the support seat 119.

[0116] In this way, the posture correction assist mechanism 114 according to the present invention can be attached to the massage bed 112 on which the patient lies in a prone position. With this structure, it becomes possible to firmly and stably apply the weight of the patient's upper body (especially the head) to the posture correction assist mechanism 114, and by utilizing the reaction force, it becomes possible to efficiently perform treatment on the patient's spine.

[0117] It goes without saying that the first tiltable support seat 115 and the first elastic connecting part 117, and the second tiltable support seat 119 and the second elastic connecting part 120 can be used individually.

[0118] Furthermore, another embodiment of the treatment device of the present invention is shown in Figure 12. This treatment device 121 includes a chest support portion 122 that supports the forward-leaning chest of a seated patient, and a head support portion 124 located above the chest support portion 122 that supports the area around the patient's face. A posture correction auxiliary mechanism 126 is provided that protrudes toward the patient's chin, located below the head support portion 124.

[0119] The posture correction assist mechanism 126 in this embodiment can be the same as the posture correction assist mechanism 114 used in the treatment device 110 illustrated in Figure 9-11. With the posture correction assist mechanism 126 of this embodiment, it is possible to reduce the weight of the head on the spine, including the cervical vertebrae, and to apply traction and other effects to the spine, including the cervical vertebrae, more efficiently using the posture correction assist mechanism 114.

[0120] Although embodiments of the present invention have been described in detail above, the present invention is not to be interpreted in any way as being limited by the description of such embodiments or the above-mentioned preferred embodiments. It can be implemented in various forms with modifications and changes based on the knowledge of those skilled in the art, and each of these forms is included within the scope of the present invention as long as it does not depart from the spirit of the present invention.
