Description

  Since the present invention relates to a technical field that has not attracted attention in the past, first, the needs of the technical field will be described.

In addition, there are no academic terms that match in this technical field, so avoid redundant redundant modifier clauses by defining and using terms.
In addition, to be able to search the definition, the definition is written with the exception of “define as” and “define as” and so on, with some inevitable exceptions. If you search with, you can refer to the definition of ankle joint blur.
In addition, for example, {{Description of ankle joint blurring}} or the like that indicates the content so that it can be searched for the convenience of referring to a complicated technical concept is searched. Then you can call up the headings sequentially.
Also, when it is difficult to understand which phrase is longer and which phrase is equivalent or where a modified clause is applied, the breakpoints in one sentence are ordered in the order of smaller semantic units. If necessary, use “,”, “;”, “:”, “::”, “.” In this order to make it easier to explain the logic.
In addition, since “and / or” is frequently used in a sentence, it is difficult to read, so “·” is defined and used as the meaning of “and / or”.

Here, a practitioner of the weight transfer operation is simply defined as a practitioner.
In addition, footwear, an insole for replacement footwear, or footwear (such as socks) is defined as footwear.
{{Explanation of joint blur of upper and lower limb joints}}
An ankle joint, a knee joint, a hip joint, a sacroiliac joint, a scapulothoracic joint, a scapulohumeral joint, an elbow joint, and a wrist joint are collectively defined as upper and lower limb joints. The joint behavior of the upper and lower limb joints (defined as movement) was intended to be the disturbing left and right joint behavior of the upper and lower limb joints that occurred during weight transfer (this is defined as joint blur). There is joint behavior.
A frequent problem among joint shakes in weight transfer movements is joint shake due to weight shifts in the upper and lower limb joints. Representative joint blurs include, for example, foot blur (joint blur at the ankle joint), knee blur (knee joint blur), hip joint blur, body axis blur (combination of upper and lower limb joint blur), eye line, etc. There is what is expressed by a common name such as blur (combination of blur of upper and lower limb joints). The cause of joint blur in weight movement is ankle joint blur.

Here, in particular, the behavior of ankle joint joint blur (ankle joint blur), which is the cause of the joint blur, will be described in detail.
{{Description of ankle joint}}
The whole foot, including the main ones in the anatomy of the thigh and subtalar joints, is called the ankle joint, the wedge boat joint, the talin boat joint, the cuboid joint, the tarsal metatarsal joint, There are many joint groups scattered throughout the foot, such as toe joints and interphalangeal joints, and it is difficult for practitioners to understand foot functions. This incomprehensible foot function is the root of all evils that make it difficult to cope with ankle joint blurring.
Therefore, assuming one virtual joint that integrates the functions of the joint group of the entire foot, a virtual ball joint whose position is the center of the thigh joint is assumed, and the virtual ball joint is defined as an ankle joint.
The “ankle joint” and related concepts are based on the foot behavior mechanism theory called the L model developed by the inventors, but the complicated behavior of the joint group of the foot can be easily explained, and will be explained using the L model.

{{Description of driver, rolling, ankle joint blurring}}
In the L model,
A three-dimensional joint behavior in which the three-axis joint behavior components of dorsiflexion or plantar flexion, pronation or diversion, adduction or abduction are combined is defined as a ball joint behavior.
In the L model, the ball joint behavior of the ankle joint is:
The main driving source that moves the body weight in the frontal direction is the ball joint behavior originating from the internal force that moves the body weight without changing the direction of the dorsiflexion flexion axis of the ankle joint to the ground. Voluntary ball joint behavior along the body mechanism (this ankle joint behavior is defined as a driver);
As an auxiliary driving source that moves the weight in the front direction of the body, the intentional plantar rolling is different from the plantar rolling by the driver without changing the direction of the ankle joint dorsiflexion buckling axis to the ground. Voluntary joint behavior of dorsiflexion and plantar flexion originating from internal force (this ankle joint behavior related to the rolling of the foot is defined as rolling);
It is a ball joint behavior that originates from an external force that occurs unintentionally when moving weight, and is a disturbance mainly in the left-right direction that blurs the direction of the ankle joint's dorsiflexion flexion axis in the ground, Involuntary ball joint behavior that generates irregular behavior of the foot (this ankle joint behavior called foot shake is defined as ankle joint shake):
Suppose there is a possibility. “Possible” means that the ankle joint shake / rolling may be zero. For example, if the ankle joint shake is zero, the foot shake does not occur, and further, depending on the rolling value, the sole does not roll and may remain flat during the ground contact.
For the L model:
The driver is a varus valgus originating from internal forces, with voluntary joint behavior that is a regular combination of dorsiflexion or plantar flexion, pronation or proversion, adduction or abduction;
Rolling is voluntary joint behavior of dorsiflexion or plantar flexion;
Ankle joint blur is mainly composed of varus and valgus originating from external force, and is an involuntary joint behavior in which dorsiflexion or plantar flexion, pronation or supination, adduction or abduction are irregularly mixed. is there:
Assuming that
Also, in the straight line that is the most basic movement of weight, the direction of the ankle joint's dorsiflexion flexion axis to the ground does not change if only the driver is rolling. The joint stability of the lower limb joint does not occur, so the body stability is maintained.

{{Description of the need to be able to distinguish ankle joint blur from driver rolling}}
However, depending on how to support the weight on the soles of the person who moves the weight, the ankle joint blur may be mixed in the driver's rolling, and the ankle joint dorsiflexion flexion axis against the ground Shaking may occur in the direction, and joint shaking may occur in the upper and lower limb joints.
Since the upper and lower limb joints are connected by muscles, tendons, and ligaments, the ankle joint blur affects each of the upper and lower upper and lower limb joints upward from the foot, causing each joint blur.
Therefore, the essential point for adapting joint blur according to the characteristics, purpose, and symptoms of the practitioner is that the resulting ankle joint blur can be controlled separately from ankle joint driver rolling.
Since driver rolling is a voluntary behavior originating from internal forces, the practitioner can easily control it intentionally.
However, with regard to the control of ankle joint blur, it is difficult to control mixing into the driver rolling because the ankle joint blur originates from external forces and is a disturbance behavior due to involuntary autonomous reflexes. Therefore, it is practically impossible to “control the ankle joint blur caused by weight shift separately from driver rolling” (hereinafter referred to as “discrimination control”).

  Accordingly, the key to distinguishing and controlling ankle joint blur is to make the ankle joint blur distinguishable from driver rolling.

  Conventionally, in the footwear industry / sports world, the ball joint behavior of a three-dimensional ankle joint is too complicated, so it is simply regarded as a torsion of the foot, and a single axis parallel to the ground, which is the inflection of the ankle joint. It was normal to pay attention to the twist around the motion axis. Further, the pronation of the ankle joint has been grasped in total without distinguishing between the components corresponding to the pronation of the ankle joint and the pronation of the driver.

  In related industries and related societies, although it has been empirically recognized that controlling foot shake caused by weight shift (ankle joint shake) leads to controlling each joint shake of upper and lower limb joints. In order to control ankle joint blur, the method of distinguishing between ankle joint blur and driver rolling has not been stepped on. Therefore, practitioners have no efficient technique to distinguish between ankle joint driver rolling and ankle joint blur, and therefore there was no efficient technique to flexibly control each joint blur of the upper and lower limb joints. is there.

{{Prevention of injury caused by ankle joint blurring}}
Ankle joint blur caused by weight shift induces each joint blur in each of the upper and lower limb joints, and even if it is a joint blur that does not cause acute damage to the joint, it continues habitually If this happens, the lateral contact with the meshing surface of the joint and the load load are the main causes of damage and deformation such as a reduction in the joint. The hallux valgus is typical for an ankle joint, and knee osteoarthritis is typical for a knee joint.
Therefore, from the aspect of preventing or correcting the damage, depending on the characteristics of various practitioners and the purpose / symptom of each practitioner who wants to prevent or correct the joint shake of which joint It is important to be able to adapt the blur flexibly.

{{Reduction and utilization of ankle joint blur}}
On the other hand, in weight movement movements of healthy individuals with strong muscles and tendons related to upper and lower limb joints in situations such as running and walking or sports, knees are flexible and powerful according to the characteristics, purposes, and symptoms of various practitioners. It is required to control each joint blur and ankle joint blur of the upper and lower limb joints expressed in the form of blur, hip joint blur, body axis blur, eye-gaze blur, or the like so as to reduce or increase.
That is, in the aspect aiming at directional stability and / or fatigue reduction and / or high output with high reproducibility in performance such as running, walking or sports:
In order to reduce directional blurring such as eye movement blurring, knee blurring, hip joint blurring, body axis blurring, and energy consumption, the joint blurring of the upper and lower limb joints, that is, the ankle joint blurring caused by it, is reduced or reduced to zero. Distinguishing and controlling;
Or, conversely, to improve the acceleration and power for braking, quick driving, and turning in the front and rear, left and right in the performance, the ankle joint is the cause to reversely use the joint blur of the upper and lower limb joints. Differentiating and controlling ankle joint blurring to increase blurring:
It is required to distinguish and control ankle joint blur with various flexibility.

As described above, in order to adapt the joint blur of the upper and lower limb joints according to the characteristics, purpose, and symptoms of the practitioner, the ankle joint blur is reduced or reduced in a manner that suits these various characteristics, purposes, and symptoms. It is important to be able to distinguish and control flexibly so as to increase.
The essential point for the practitioner to distinguish and control the ankle joint shake was to make the ankle joint shake distinguishable from the driver rolling.
However, there has been no behavior theory related to ankle joint blur caused by weight shift, which has been explained in detail to the theory of foot behavior mechanism, which is easy to understand for practitioners. Also, of course, there was no technical idea such as footwear to make ankle joint blur distinguishable from driver rolling.

{{Technical field to which the present invention belongs}}
The present invention relates to footwear and the like, and more particularly, to footwear and the like characterized by a configuration that makes ankle joint blur distinguishable from driver rolling.

There is no conventional footwear or the like according to the present invention (hereinafter referred to as the present footwear or the like).
Therefore, the prior art will be described below with respect to an example of conventional footwear (hereinafter referred to as conventional footwear) that seems to be closest to the footwear of the present invention.

2. Description of the Related Art Conventional footwear and the like include a configuration for guiding the behavior of a user such as footwear by uniquely matching the configuration of the footwear to a specific purpose and partially restraining the behavior of the foot. For example, footwear with the primary purpose of avoiding foot fatigue, ankle joint damage such as hallux valgus and / or running instability in sports, etc. due to torsion (pronation and gyration) There are many.
As a typical example, there is “Shoes with a shank portion” of the invention of Japanese Patent Application Laid-Open No. 2002-262903 (P2002-262903A) of Patent Document 1.
Another typical example is
JP, 2005-95388 (P2005-95388A) Title of invention "Shoes" is available.

The above-mentioned “shoe having a shank portion” assumes that the rotation axis of the prosthetic movement of the forefoot is in the arch (the middle foot in anatomy), and the front foot (the phalanx in the anatomy) around the rotation axis. Part) is based on the premise of foot behavior mechanism that pronation movement occurs.
On the other hand, the above-mentioned “shoes” are a straight line that runs planarly on the bottom surface of the foot where the rotation axis of the pronation movement of the forefoot part (the phalanx part in anatomy) exists in the middle foot part. As described in number 0099, this is based on the premise of a foot behavior mechanism in which a prosthetic supination motion of the forefoot occurs with the shoe center line (anatomically, the long axis of the foot) as the rotation axis.
In other words, any of the above-mentioned conventional footwear is characterized by the premise of the foot behavior mechanism that the pronation of the phalanx is caused by the pronation that rotates around the rotation axis behind the middle foot. It is the structure which took the means which functions based on.

Thus, all conventional footwear etc .;
It is not footwear intended to distinguish and control ankle joint blur from driver rolling in a variety of flexible ways;
It was constructed based on the technical idea of guiding the torsion of a user such as footwear in a unique direction.

Japanese Patent Application Laid-Open No. 2002-262903 (P2002-262903A) Name of Invention “Shoes with Shank” Applicant Dynagate Corporation and 1 other company Japanese Patent Application Laid-Open No. 2005-95388 (P2005-95388A) Name of Invention “Shoes” Applicant Mitsuno Corporation

  Hereinafter, problems to be solved by the present invention will be described.

{{Problems of the prior art}}
In the technical idea of the conventional footwear described above;
Focusing only on the pronation of the midfoot, out of the pronation of the foot, metatarsal (arch), and forefoot (phalangeal), the instability is the forefoot Because it is considered to be caused by improper torsion (pronation or pronation) around the metatarsal pronation / extraction movement axis;
Unable to control ankle joint blurring that occurs throughout the foot;
The deficiency that happens.
In addition, the ball joint behavior of the ankle joint is, for example, the total behavior of the behavior of ankle joint driver rolling and ankle joint blur when walking;
The driver rolling also changes depending on the size of the dorsiflexion buckling caused by the walking stride size;
If the pronation and gyration of the driver is not constrained from the pronation and gyration of the ankle joint blur, the pronation and gyration of the driver is necessary for stable weight movement. There is a risk of being restrained.
As described above, there is a problem that none of conventional footwear and the like can be an auxiliary tool that can control ankle joint blur from driver rolling.

  In addition, twisting of the ankle joint (pronation / pronation) is univocally restrained in total forefoot pronation / extraction (for example, JP 2005-95388 (P2005-95388A)) 6) or 7) of “Shoes”), the ankle joint blur cannot be flexibly controlled from the driver / rolling according to the characteristics, purposes, and symptoms of each wearer. It was not possible to adapt to the characteristics, purpose, and symptoms of joint blurring of the upper and lower limb joints.

  In addition to the examples of the conventional footwear described above, there is no conventional footwear or the like that is an auxiliary tool that can distinguish ankle joint blur from driver rolling.

{{Necessity of the present invention}}
In order to make it possible to adapt the joint blur of the upper and lower limb joints according to the characteristics, purpose, and symptoms of the practitioner, the ankle joint blur of the ankle joint is distinguished from the driver rolling and the characteristics, purpose, It is necessary to control flexibly according to the symptoms. Therefore, it is essential that the practitioner has an auxiliary tool that can distinguish ankle joint blur from driver rolling.

{{What the present invention aims at}}
If there is an auxiliary tool that can distinguish ankle joint blur from driver / rolling, the auxiliary tool controls the ankle joint blur separately from driver / rolling, and adjusts the upper and lower limb joints according to its own characteristics, purpose, and symptoms. Give practitioners a way to adapt joint blurring.
Therefore, an object of the present invention is to provide an auxiliary tool for distinguishing an ankle joint shake that can distinguish an ankle joint shake from driver rolling.

{{Explanation of the rationale of the L model}}
Before explaining the configuration of the footwear of the present invention which is the auxiliary tool, first, the foot of the Lanznos model (this is defined as the L model) on which the footwear of the present invention (means for solving the problems) is based. It is essential to explain the behavior mechanism theory. This is because the present footwear or the like is based on the L model, and therefore the present footwear or the like cannot be explained unless terms and logic unique to the L model are used.
The L model is an unprecedented unique foot behavior mechanism theory developed by the inventors, which makes it possible to distinguish ankle joint blur in ball joint behavior of an ankle joint during weight movement from driver rolling. It is.
Here, regarding the L model, the rationale part and the L model type zero blurring reference line specifying method will be described. In other words, the footwear of the present invention can be implemented by the L model zero blur reference line specifying method described later, but it cannot be said that the reason for the L model is within the common sense, public knowledge, and public use of those skilled in the art. The reasoning part of the L model is also written to fill the gap.
Hereinafter, the rationale part of the L model will be described while defining L model terms.

{{Explanation of axes, lines, line lines}}
In the description of the present invention based on the L model, many similar lines appear and are confusing. Therefore, in order to distinguish between the lines belonging to the body and the other lines, the lines belonging to the body will be specially expressed by the word “axis”, and the other lines will be grouped as “lines” and “lines”. Is represented by the term “line”.

  The L model is theoretically developed on the assumption that the ground means the earth surface of a horizontal smooth plane or a floor surface equivalent thereto. If the ground is not a horizontal smooth plane, it can be used simply by finely correcting the theory obtained by this assumption.

The basic skill of the joint blur control skill of the upper and lower limb joints in weight movement is the control skill of the joint blur of the upper and lower limb joints in the straight running motion;
The control skill for joint blurring of the upper and lower limb joints in weight movement movements other than straight advancement movements is also an application and application of the joint blurring control skill for upper and lower limb joints in straight forward movements;
It has been thought of in the past. The L model follows that idea.
The cause of joint blur in the upper and lower limb joints is ankle joint blur.
Therefore, in the L model, the basic skill of controlling ankle joint blurring in weight movement movement is the control skill of ankle joint blurring in straight forward movement movement;
It is assumed that the ankle joint blur control skill in the weight movement operation other than the straight advance motion is an application / application of the ankle joint blur control skill in the straight advance motion.

  In other words, the practitioner can apply and apply the muscle movement chain acquired by discriminating control of the ankle joint movement in the straight-ahead movement, and flexibly move in the straight-line movement according to the characteristics, purpose, and symptoms of the practitioner. Assume that it becomes possible to control ankle joint blurring in weight movement operations other than the above.

  In the L model, the ankle joint motion is zero, that is, the joint behavior of the ankle joint with only driver rolling produces a natural weight movement motion by performing a motion chain with each joint behavior of the other upper and lower limb joints. Such a weight movement operation is defined as an L model type weight movement operation.

{{Description of the bottom virtual ground}}
In addition, the ground contact part such as footwear that is in contact with the ground rolls the ground (assumed to be a horizontal plane) or keeps flat with the ground as the body weight moves, but the ground contact part is subject to rolling and ankle joint behavior. And deform. Accordingly, when a certain three-dimensional shape belonging to footwear or the like or a foot is viewed in plan, it is complicated to obtain a shape in plan view by projecting onto the surface of the ground contact portion.
Therefore, in the L model, a concept of a virtual ground attached to footwear or the like called a bottom virtual ground is introduced.
Now, a certain virtual horizontal plane (D) in the worn footwear is:
A virtual horizontal plane (D) belonging to footwear, etc .;
A virtual horizontal plane (D) that is assimilated with the ground plane and does not move relative to the ground plane only while the footwear is in contact with the ground;
A virtual horizontal plane (D) in which a point obtained by projecting the center of the ankle joint from the upper side in the vertical direction into its own surface is a point of attachment to a ground contact surface such as footwear;
A virtual horizontal plane (D) in which the attachment point moves in its own plane according to the movement of the center of the ankle joint due to weight movement:
In this case, the virtual horizontal plane (D) is defined as the bottom virtual ground.
The bottom virtual ground is used as a reference plane for footwear when the ground contact surface of the worn footwear is not a flat surface, or even if the ground contact surface is complicatedly displaced or deformed with respect to the ground even if it is a flat surface. Convenient. In other words, if the bottom virtual ground is introduced, for example, if the trajectory of the three-dimensional motion at the center of the ankle joint is projected onto the virtual bottom virtual ground instead of projecting onto the ground contact surface such as footwear that undergoes complex displacement / deformation. , It is a movement trajectory in a horizontal plane where there is no movement / deformation and repeats grounding / leaving with footwear etc., which is close to the image perceived by the practitioner and easy to understand.

{{Description of scanning projection view}}
Furthermore, the L model introduces the concept of scanning projection vision and will be described.
In the L model, a shape that moves three-dimensionally moves in a complex manner (movement / movement) with respect to the ground during weight movement, and the weight moves while the bottom surface of the footwear or the like keeps rolling or flat. Handle. For example, considering the shape belonging to the foot, which is a three-dimensional trajectory of the center of the ankle joint, the center of the ankle joint moves in a complex manner during the weight movement operation. Too complex to image.
In addition, the shape of the sole contact part of footwear, the bottom part of footwear, the upper covering part, etc. moves with the foot and has a complicated three-dimensional structure. The movement is too complicated to understand. Usually, when a three-dimensional still life is projected onto a horizontal plane, a two-dimensional shape in a plan view can be obtained, and thus a plan view method is convenient. However, the present invention deals with a three-dimensional complex shape that is displaced and deformed, and thus a plan view method. Then there is a contradiction.
In view of this, the L model introduces the concept of “scanning projection view” that can be handled in a manner similar to planar view.
That is, a cross-section of the foot, footwear, etc. cut perpendicularly to the front of the body including the center of the ankle joint at a certain moment when the body moves according to weight shift (that is, at the attachment point of the ground contact surface and the bottom virtual ground). A virtual operation of scanning (scanning) a cross section of the image in each moment and projecting and recording an arbitrary three-dimensional shape (A) located in the cross section from above in the vertical direction onto the bottom virtual ground. If the shape (B) is obtained in the bottom virtual ground when the cross-section has moved from the rear end to the front end of the worn footwear or the like, the shape (B) disappears in height and the bottom portion It becomes a two-dimensional shape in the virtual ground. In this way, the scanning of the three-dimensional shape (A) into the two-dimensional shape (B) in the bottom virtual ground obtained by projecting and recording on the bottom virtual ground from above in the vertical direction while scanning (scanning) is performed. Defined as projected. When the shape (A) is not displaced / deformed, “scan projection view” has the same meaning as “plan view”.
In the L model, the relationship between the shape (A) and the shape (B) is expressed, and the shape (B) is simply referred to as “in scanning projection view (or in scanning projection view or scanning). The meaning of “scan projection view” is used so that it can be expressed as “the shape (A)” projected or viewed). Therefore, except for the case of particularly emphasizing, the expression “scanning projection view” alone is sufficient even if it is not expressed as “scanning projection view onto the bottom virtual ground”.
For example, when a three-dimensional shape, for example, a three-dimensional valgus-valgus motion axis of an ankle joint is actually scanned and projected on the bottom virtual ground, the varus-valgus motion axis scanned and projected is It becomes a two-dimensional shape called a straight line. These two-dimensional shapes are close to the actual senses for the practitioner and are easy to understand. Therefore, the L model adopts a two-dimensional method called scanning projection vision.
When scanning and viewing the shape of feet, footwear, etc .;
Even if there are complex displacements and deformations of the ground contact parts such as footwear;
When the wearer, such as the footwear, wants to sense the behavior of the shape (A) belonging to the foot, the footwear, etc. during the weight transfer operation in two dimensions;
The bottom virtual ground belongs to the footwear, etc., regardless of the direction of the footwear, etc., feet, east, west, south, north, and south, so that the three-dimensional shape ( This is convenient because the relationship between A) and the two-dimensional shape (B) can be expressed in footwear or the like.

{{Description of bottom fulcrum and bottom fulcrum trajectory}}
In the L model, the concept of a bottom fulcrum and a bottom fulcrum locus is introduced.
At the moment of the ground contact foot at a certain moment, the load is supported by the area of a certain area on the bottom surface of the foot of the ground contact foot. A point is defined as a bottom fulcrum, and a trajectory representing a time-series change in bottom fulcrum position drawn by the bottom fulcrum in the plane of the bottom virtual ground during the weight movement operation is defined as a bottom fulcrum locus. The bottom fulcrum is the center point in the bottom virtual ground where the resultant force works, and the force is actually concentrated on only the bottom fulcrum, meaning that no sole pressure is applied to the sole area on both sides of the bottom fulcrum locus. It should be noted that this is not always the case.
Also, the base fulcrum trajectory fluctuates from step to step depending on the foot landing movement, weight shift, body posture balance, running stride and movement rhythm, etc. May not necessarily extend from the rear end of the rear part of the foot to the entire front part of the front part of the foot, but may be drawn only partially.
The human foot has a tactile (somatosensory) nerve that senses the bottom fulcrum and can easily sense the position of the bottom fulcrum. If considered as a microcosm of the weight movement behavior in the movement movement, the abstract and ambiguous weight movement behavior is made clear to general practitioners with a concrete figure pattern called a bottom fulcrum locus.

{{Description of relationship between ankle joint center and bottom fulcrum}}
For the L model:
The body weight (gravity) acts on the center of gravity of the body according to the body weight movement at each moment of the body weight movement movement, and goes directly below the vertical position;
Through the lower leg of the stance leg to the center of the ankle joint;
Then, after passing through the center of the ankle joint, it is applied to the bottom virtual ground such as footwear via the foot;
In addition, the point in the scanning projection view of the center of the ankle joint is a bottom fulcrum in the bottom virtual ground;
Also, the trajectory in scanning projection drawn by the ankle joint center becomes the bottom fulcrum trajectory in the bottom virtual ground:
Assume that This assumption seems to be a reasonable assumption because the ankle joint center trajectory and the bottom fulcrum trajectory in scanning projection view in an actual walking experiment almost coincide.

{{Explanation of knowledge by walking experiment}}
The inventors discovered several facts related to the foot behavior mechanism through walking experiments.
The knowledge obtained from the discovery forms the theoretical basis of the L model.
The discovery is described below.
First, if the base fulcrum is placed on a certain fulcrum trajectory in the bottom virtual ground and the body is moved at a constant speed, the ankle joint blur does not occur at zero, and conversely, the bottom fulcrum Is controlled so as to move away from the bottom fulcrum locus, and an ankle joint shake can be generated reproducibly and reliably. That is, there is a discovery that there is a bottom fulcrum locus drawn in the plane of the bottom virtual ground such that the ankle joint blur becomes zero when the bottom fulcrum traces in the plane of the bottom virtual ground. In the L model, the bottom fulcrum locus is defined as a zero blur locus.
The second is that the zero blur locus draws a curve such as 2 in FIG. 2, and if the curve is simplified, a fold line such as 1 in FIG. 2 is drawn on the bottom virtual ground.
Third, with the zero blur trajectory drawn on the bottom virtual ground as the boundary line, if the bottom fulcrum is applied to the inner side of the zero blur trajectory, blurring such as varus will occur, and if the bottom fulcrum is applied on the zero blur trajectory, the ankle The joint blur is zero, and when the bottom fulcrum is applied to the outer side of the zero blur reference line, blurring such as valgus occurs.

Therefore, when the bottom fulcrum locus overlaps with the zero blur locus, the ankle joint blur is zero. The fact that the ankle joint blur is zero means that the behavior of the ankle joint caused by the weight shift operation is only driver rolling.
Further, when the weight shift operation is performed by moving the bottom fulcrum locus away from the zero blur locus, the behavior of the ankle joint that occurs is the driver rolling and the ankle joint blur.
Therefore, if the difference between the two is recognized, ankle joint blur can be distinguished from driver rolling.
Therefore, when the ankle joint blur is distinguished from the driver rolling by the difference, the zero blur trajectory becomes a reference line for measuring the movement of the bottom fulcrum in the bottom virtual ground. Therefore, the zero blur trajectory is redefined as the zero blur reference line. .
In the L model, in order to control the ankle joint blur, the bottom fulcrum locus may be controlled with respect to the zero blur reference line.

{{L model representation of findings from walking experiments}}
If the knowledge obtained from the walking experiment is reviewed as a viewpoint based on the zero blur baseline;
The first is that when the bottom fulcrum is on the zero-blur reference line, the ankle joint blur does not occur at zero feet during the weight shift operation, and conversely, the bottom fulcrum is zero-blur based. If it is away from the line, it will reproducibly produce ankle joint blurring;
Second, the zero-blur reference line is drawn on the bottom virtual ground as a curve such as 2 in FIG. 2 (zero-blur reference curve described later), and in a simplified manner, a fold line as illustrated in FIG.
Third, with the zero-blur reference line drawn on the bottom virtual ground as the boundary line, if the bottom fulcrum is applied to the inner side of the zero-blur reference line, a blur such as varus occurs and the bottom fulcrum is placed on the zero-blur reference line And ankle joint blur is zero, and if a bottom fulcrum is applied to the outer side of the zero blur reference line, blurring such as valgus occurs;
It becomes.

{{Theoretical verification of zero blur reference line and zero blur reference broken line}}
The L-model is the foot behavior mechanism theory related to the zero-blur baseline developed from the meaning of the knowledge.
The theoretical verification of the foot behavior mechanism theory will be described below.
As shown in FIG. 4, from an anatomical point of view, in a scanning projection view, an action that is autonomously reflected by a load applied to the bottom fulcrum and mainly has a varus of the foot (hereinafter referred to as a varus equality action). Distribution of the force action point of the muscle group that causes the action point (hereinafter referred to as valgus action) and the action point of the valgus (hereinafter referred to as the valgus action);
The inner valgus side boundary line 20 is divided into the inner instep side 31 and the outer instep side 30 using the boundary line 20 of the varus valgus region (this is defined as the varus / valgus equality boundary line) 20 as a watershed. It is distributed separately from the inner valgus side 31 to the varus equal area, and from the varus / valgus equal area boundary line 20 to the outer flank 31 to the valgus equal area.
In the varus equality region, as the force action points of the muscle group having varus equality, the anterior tibial muscle 21, the posterior tibial muscle 22, the long finger flexor muscle 23, the long finger flexor muscle 24, and the soleus / hyfuku muscle 32 They are distributed;
In the region of valgus iso-action, as the force action point of the muscle group having valgus iso-action, the long extensor extensor muscle 25, the long extensor muscle 26, the third peroneal muscle 27, the long peroneal muscle 28, and the short peroneal muscle 29 They are distributed. In the L model, it is considered that the force action points of these muscle groups act on the joints between the tarsal joints including the subtalar joint to cause varus or valgus in the rear part of the foot.
In addition, there is a valgus etc. in terms of the continuity of the natural world between the area of valgus and valgus action caused by reflection against the stimulation by the ground reaction force (external force) of the load applied to the bottom fulcrum. The L model considers that there should be a boundary line where the varus and the varus are just balanced. The balanced boundary line is considered to be the varus / valgus equilateral boundary line 20 in the rear part. That is, when a load applied to the bottom fulcrum is applied to the valgus-equilateral boundary line 20, it is considered that the valgus etc. of the valgus due to the load (external force) becomes zero. That is, the valgus due to the external force is caused by the external force and the direction of the dorsiflexion buckling axis is shaken.
In other words, if the bottom fulcrum rides on the varus / valgus equality boundary line 20, the ankle joint blur (the valgus / valgus etc. originating from the external force) becomes zero, and if the bottom fulcrum moves away from the varus / valgus equality boundary line 20. From the viewpoint of the occurrence of ankle joint blurring (valvular / valgus etc. originating from external force) and the continuity of the natural world, the valgus-equality region boundary line 20 and the zero blurring trajectory (zero blurring reference line) are the same in the rear part of the foot. It seems reasonable to think that.
The existence of the varus / valgus equilateral boundary 20 at the rear of the foot is well known anatomically, and the valgus / equilateral boundary 20 is the foot of the zero blur locus (same as the line 1 in FIG. 2) obtained by the walking experiment. It almost coincides with the position of the rear part.
On the other hand, the presence of the varus / valgus equilateral boundary 20-A in the front part is not anatomically established;
The action of the long finger flexor landing point 24-A is a pure varus, and the long finger flexor landing point 23-A acts valgus;
In the L model, the inner valgus region is separated into the inner valgus side 31 from the inner valgus boundary region 20-A, and the outer valgus region is separated from the valgus outer region boundary line 20 toward the outer side 31. Suppose.
Also, like the rear part of the foot, the front part should be considered to have a boundary line that balances the valgus and the varus, etc., between the valgus region and the valgus region, The balanced boundary line is considered to be the varus / valgus equality boundary line 20-A.
As a phenomenon discovered by the walking experiment, there is a zero blur reference line not only in the rear part of the foot but also in the front part, and the line 1 or 2 in FIG. 2 is the zero blur reference line (zero blur locus).
Regarding the phenomenon of the anterior part of the zero-blur reference line obtained in this walking experiment, in the L model, when the bottom fulcrum moves to the anterior part of the foot, the tarsal metatarsal joint, metatarsal joint, and interphalangeal joint Moreover, the above experimental results are in good agreement when the muscle group having the varus and valgus action and the muscle group having the valgus action and the like described above are interpreted as an equilibrium phenomenon caused by the same action in the rear part of the foot.
Therefore, in the base model of the L model, the fold line 1 in FIG. 2 consisting of the varus / valgus equilateral boundary line 20 of the rear foot and the varus / valgus equilateral boundary line 20-A of the forefoot is represented by the entire foot. In the base model of the L model, the entire fold-shaped valgus-inversion valgus boundary line (1 fold line in FIG. 2) drawn on the virtual bottom of the foot is zero-blurred. It is defined as the standard broken line.

Furthermore, in the L model, there is a ground that can be interpreted from the anatomical and mechanical viewpoints that the zero-blur reference fold line overlaps the zero-blur trajectory or the varus / valgus equilateral boundary of the entire foot.
That is, in anatomy;
The ball joint that combines only the two joints, the thigh joint and the sock joint, is called the “ankle joint”;
The three-axis ball joint behavior of the ankle joint is the valgus valgus which is the rotation about the valgus valgus motion axis of the ankle joint and the dorsiflexion buckle which is the rotation about the ankle dorsiflexion flexion motion axis. It can be integrated into the axial behavior.
The virtual “ankle joint” is a concept unique to the L model and is different from the “ankle joint” in anatomy;
In the base model of the L model, it is assumed that the ankle joint and the ankle joint coincide with each other in the rear part of the foot.
Then, mechanically, as long as the bottom fulcrum (center of the ankle joint in the scanning projection view) moves on the valgus-valgus motion axis in the scanning projection view, the weight from the bottom virtual ground applied to the bottom fulcrum is dynamic. The vertical reaction force (i.e., external force) does not generate a rotational moment (i.e., ankle joint shake originating from the external force) around the valgus-valgus motion axis. At this time, a rotational moment around the dorsiflexion buckling motion axis is generated, but this component does not blur the direction of the dorsiflexion buckling motion axis toward the ground, so it is a component of ankle joint blurring. Must not. That is, at least in the rear part of the foot, as long as the bottom fulcrum moves on the valgus-valgus motion axis in the scanning projection view, the ankle joint blur is zero, so the varus-valgus motion axis in the scanning projection view is It is reasonable to assume that it coincides with the zero-blur reference fold line and coincides with the varus / valgus boundary line 20.
Therefore, in the L model, it is considered that the varus / valgus motion axis in the scanning projection view coincides with the zero-blur reference fold line in the rear part of the foot.
Anatomically, according to Inman's “The joints of the ankle, P26-P43, The Williams & Wilkins Co. publication”, the valgus-valgus motion axis is the foot of a scan projection view in the case of Westerners. There is a data example in which the angle with respect to the major axis 3 is distributed within a range of 12 to 34 degrees in scanning projection view. On the other hand, in the data example for Japanese, the angle with respect to the long axis 3 of the foot is a projection view and the median of the distribution is 16 degrees (3 to 29 degrees if the distribution size is plus or minus 13 degrees) (for example, , Tsutomu Yamazaki, “Theory and Technology of Orthopedic Physiotherapy”, Medical View, Tokyo, pages 36-61).
In the L model, in consideration of these findings, the valgus-valgus motion axis in the world is within the range of 3 to 45 degrees in the scanning projection view with respect to the major axis 3 of the scanning projection view with the grounded foot. It is assumed that it is distributed.

{{Theoretical verification of zero blurring standard curve}}
On the other hand, the case where the zero blur reference line is a curve as shown in FIG.
In weight movement movement of correct constant-velocity straight walking, the planar locus drawn by the center of gravity of the body with respect to the ground is almost a sine curve or cosine curve (hereinafter referred to as a sine curve because the shape is the same). This is well known from the past.
In the L model, it is assumed that the body center of gravity moves circularly with a small radius including zero around the body axis, so if the body is moving at a constant speed, the body center of gravity moves circularly with a small radius. The direction component is small compared to the amount of ground position change due to walking speed, so it can be ignored, the left-right direction component of the body center of gravity change should draw a sine curve, and the ground plane trajectory of the left and right body center of gravity is a sine curve Assuming that That is, in the L model, it is assumed that the correct weight-changing motion of the straight walking at constant speed is a weight-shifting motion in which the center of gravity of the body performs a circular motion with a small radius including zero around a body axis that does not move from side to side. To do.
In addition, there is a stance phase that supports the weight with only one foot in walking where the weight-bearing feet are switched alternately left and right;
This can be grounds for the assumption of the L model that the bottom fulcrum trajectory forms a sine curve parallel to or overlapping with the sine curve of the plan view trajectory of the body center of gravity on the ground on the weight support foot.
In addition, in the weight movement operation of correct walking at a constant speed, the plan view locus of the body center of gravity on the ground is a clean sinusoidal curve because the body center of gravity moves while following the rotation around the body axis. Because it is considered that there is no blurring of the body;
A correct constant-velocity straight-walking weight movement corresponds to a weight movement with zero ankle joint blurring;
The weight movement movement with zero ankle joint motion corresponds to the case where the plan view locus of the body center of gravity on the ground is a sine curve;
And the L model are assumed to be reasonable.
On the other hand, in the weight shift movement with zero ankle joint blur, the bottom fulcrum locus overlaps the zero blur reference line (zero blur locus);
Since the weight is a heel on the bottom fulcrum, the plan view locus of the body center of gravity (weight action point) and the bottom fulcrum locus are parallel or overlapping heels, so if the plan view locus of the body center of gravity forms a sine curve, the bottom fulcrum locus Is a sinusoidal curve;
If the ankle joint shake is zero, the bottom fulcrum locus forming the sine curve is a zero shake locus (zero shake reference line), which means that the zero shake reference line also forms a sine curve.
From these facts, in the L model foot structure model of the L model, the sine curve 2 in FIG. 2 drawn on the bottom virtual ground is defined as a zero blur reference curve.

From the above, in the L model foot structure model of the L model, as explained in the example of FIG. 5 (a), the zero blurring reference curve 2 is the left and right directions of the front of the body in the correct constant-speed straight walking. It is assumed that it corresponds to a portion 2-A obtained by cutting off a part of a sinusoidal locus 14 (or a sinusoidal locus parallel to the center of gravity) in the plan view drawn around the center line 18.
At this time, it is desirable to specify the left and right zero blurring reference curves 2 so that the left and right are mirror-symmetric with each other and are on the same sine curve 14.
These are the symmetrical circulation of walking motion and smoothness that does not cause body blurring during the weight-supporting foot switching period of the left and right feet (smoothness that does not cause secondary ankle joint blurring due to body shaking) It is a necessary condition to satisfy.
The requirements for circulation and smoothness are satisfied if the left and right zero blurring reference curves are on the sine curve 14 and are mirror-symmetric to each other.
because;
In a constant-velocity straight-line walk that is cyclically symmetrical, repeating left and right feet alternately, the left and right feet are alternately left and right mirror-symmetric at the timing shifted by one step (equivalent to a half cycle of a sine curve). Walking with the left and right feet in harmony with each other;
The sine curve of one foot at a certain moment and the sine curve of the other foot at that moment are shifted by a half cycle (180 degrees). If the sine curve of the other foot is shifted by a half cycle, the left and right sine curves are mirror-symmetrical. Because
First, the circulation is satisfied if the left and right zero blurring reference curves are mirror-symmetric with respect to each other.
The remaining smoothness is:
The fact that the planar locus of the movement of the body center of gravity draws the sine curve 14 neatly means that there is no movement of the body center of gravity during the weight-supporting foot switching period, that is, the ankle joint movement is zero;
In a state where the ankle joint blur is zero, the bottom fulcrum locus is a zero blur locus and coincides with the zero blur reference curve;
Assuming that the plane view trajectory of the body centroid movement (ie, the sine curve 14) overlaps or is parallel to the bottom fulcrum trajectory as previously described:
From the bottom fulcrum trajectory, i.e., when the ankle joint blur is zero, the zero blur reference curve will overlap or be parallel to the sine curve 14:
This is because the left and right zero blurring reference curves are satisfied if they are alternately placed on the sine curve 14.
As described above, even if the bottom fulcrum is moved along the left and right zero blurring reference curve 2 cut out from the same single sine curve 14 so as to be mirror-symmetrical to the left and right, even if the body weight support foot is switched, In other words, ankle joint blur should not occur.
What is related to the zero blur reference curve 2 described above also applies to the zero blur reference folding line 1 in the base model of the L model in which the zero blur reference curve 2 is simplified. In the example of FIG. 5B, the left and right zero-blur reference fold line 1 corresponds to a portion 1-A obtained by cutting out a part of a fold line connection 15 (or a connection of parallel fold lines) obtained by simplifying the sine curve 14. Assume that. That is, it is desirable that the left and right zero blurring reference folding lines 1 are specified so that the left and right sides are mirror-symmetric with each other and are on the same tangential connection 15.

{{Description of the concept of switching harmony}}
Thus, in a state where the body front direction lines (19 in FIG. 3) of the left and right feet are set so as to overlap or be parallel to the body front direction center line 18;
The left and right zero shake reference curves or the zero shake reference folding lines are left and right mirror-symmetrical so that the left and right zero shake reference curves are on the same sine curve 14, or the zero shake reference fold line is on the same fold line connection 15. The meaning of “switching harmony” is defined so that it can be expressed by specifying that the left and right zero blurring reference curves or zero blurring standard broken lines are “switching harmony”.
In a walking experiment, if you walk with the bottom fulcrum trajectory aligned with the left and right zero shake reference curve or zero shake reference fold line specified to harmonize switching, ankle joint shake will not occur, and the driver or driver and rolling stable and smooth weight It was confirmed that the movement was reproducible.

As will be described in detail later, in the L model foot structure model of the L model, the zero shake reference curve 2 is used as the zero shake reference line, and in the base model of the L model, the zero shake reference folding line 1 is used as the zero shake reference line.
In the L model, it is assumed that the relationship between the zero blur reference curve 2 and the zero blur reference broken line 1 is actually a relationship in which the zero blur reference curved line 2 is simplified as the zero blur reference broken line 1.
However, when both are specifically specified, as an expedient method in the L model, on the contrary, a zero blurring standard folding line 1 that is easy to identify is first identified and transformed into a sine curve based on the zero blurring standard folding line 1 as a base. Is used as the zero blurring reference curve 2.

{{The person skilled in the art can confirm the L model rationale by a simple walking experiment}}
The above explains the rationale part of the L model.
Although the L model is a hypothesis, the behavior of the ankle joint blur according to the L model described above is in good agreement with the actual walking experiment behavior of the ankle joint blur, so the L model is a theoretical model that is close to the actual state of the joint behavior of the ankle joint. it is conceivable that.
Moreover, the above-described walking experiment behavior result can be easily confirmed by a person skilled in the art by performing a follow-up experiment with a very simple walking experiment using his / her feet. In other words, since ankle joint blur affects the upper joints, by observing the motion of the knee joint blur or line-of-sight blur that is the closest to the ankle joint and the left and right blurs are easy to detect, It can be confirmed that they are distinguishable. For example, if there is no ankle joint shake at the knee joint and only a driver / rolling gait, it should be touched by hand and there should be no left / right blur of the knee joint. There is a trap. If you describe the follow-up experiment method, measure the bottom fulcrum locus when showing knee joint blur using a foot pressure measuring instrument and / or pressure sensitive paper, and when the knee joint blur is zero, the ankle joint blur is zero Since it is time, the relationship between the zero blur reference line, the bottom fulcrum locus, and the ankle joint blur can be easily confirmed as the joint blur of the knee joint.

{{Explanation of L model type zero blurring reference line identification method}}
Hereinafter, a method for identifying the zero blur reference line will be described specifically in order to apply the L model to the auxiliary tool according to the present invention.
A specific method for specifying a zero blur reference line based on the L model described below is defined as an L model zero blur reference line specifying method.

In the L model, a simple model called “base model” is considered as a base for deriving the “L model foot structure model”, and the L model foot structure model is derived from the base model. However, although the base model is slightly less accurate than the L model foot structure model, it is simple and easy for practitioners to understand and sufficiently practical.
In the L model, the base model can be applied to the auxiliary tool according to the present invention in the same manner as the L model foot structure model.

For the L model, as the base model:
Treat the middle foot part and the foot part as an integral elastic body block, and define the elastic body block as the rear part of the foot;
Treat the rest of the midfoot and phalanx as a single elastic block, defining the elastic block as the forefoot;
The foot is composed of two elastic blocks, the rear part of the foot and the front part of the foot:
Think about the model.
In the base model, regarding the dorsiflexion buckling of the ankle joint, a model is considered in which the dorsiflexion buckling is performed sequentially in accordance with the weight shift steplessly on the entire foot without distinction between the rear part of the foot and the front part.
In the L model, since the center of the ankle joint in the scanning projection view is the bottom fulcrum, the dorsiflexion buckling axis of the ankle joint seems to stick to the bottom fulcrum and move on the bottom virtual ground in the scanning projection view. This is similar to the refraction axis of a tank's caterpillar moving across the ground. For this reason, it is assumed that the bottom surface of the foot can be kept flat during the weight movement operation, and can behave like a round rolling surface.

  Further, in the base model of the L model, the break point (5 in FIG. 2) of the zero-blur reference folding line in the scanning projection view is defined as the refraction point. The inflection point 5 may protrude from the foot or may protrude from the profile of the foot viewed by scanning projection.

On the other hand, as an L model foot structure model:
The foot is a model in which the rear part of the foot and the front part of the foot (anatomically, the foot, middle foot, and phalanx) are integrated elastic blocks.
That is, in the L model foot structure model, the bottom fulcrum trajectory is a model in which the above-described zero shake reference folding line 1 is deformed and distorted, and a sinusoidal zero shake reference curve is drawn in the bottom virtual ground.
In the L model foot structure model, the same kind of ankle joint dorsiflexion buckling as in the base model is considered.
In the L model foot structure model, the zero-blur reference fold line (1 in FIG. 2) drawn in the bottom virtual ground is smoothly deformed and the sine curve (2 in FIG. 2) drawn in the bottom virtual ground is the zero-blur reference curve. is there. Normally, the zero blur reference curve 2 does not pass through the refraction point 5 of the zero blur reference folding line 1.

In the L model, the driver is a behavior used to walk while keeping the dorsiflexion and flexion axis of the ankle joint constant with respect to the frontal direction of the ankle joint. It happens, and if it is just driver rolling, it will be assumed that there is no blurring of the foot.
Rolling also causes dorsiflexion buckling around the axis of dorsiflexion buckling motion perpendicular to the front of the body at the position of the center of the ankle joint, that is, the position of the bottom fulcrum, as seen in scanning projection view;
Depending on the size of the rolling and the direction of rolling, the plantar may not roll and the plantar may remain flat, and conversely, the plant may roll more than the plantar rolls. .

  Here, the shape X is smoothly deformed into an approximate shape Y, or only an excess portion of the shape X is cut off to form the shape Y, or the shape X is scanned and projected to form the shape Y, etc. The meaning of “base” is expressed so that “shape Y based on shape X” or “shape X that is the base of shape Y” can be expressed when shape Y is derived by applying a certain operation to shape X. It is defined as the meaning of “corresponding Omoto”.

  Referring to FIGS. 2 and 3, in the L model, the refraction point 5 and the zero blur reference fold line 1 are specified in the bottom virtual ground, and the zero blur reference fold line 1 is smoothly deformed to specify the zero blur reference curve 2. In this way, the zero blur reference curve 2 is derived based on the zero blur reference fold line 1 in the bottom virtual ground.

A specific method of specifying the zero blur reference line will be described with reference to FIG.
In the L model, the zero blur reference line is based on the zero blur reference curve or the zero blur reference folding line, and the zero blur reference curve is derived based on the zero blur reference folding line. Therefore, finally, the zero blur reference line is based on the zero blur reference broken line.
In the L model, the left and right zero shake reference fold lines are specified so as to “harmonize switching”. Therefore, if the zero shake reference fold line can identify the rear part of the foot, the fold line connection 15 can also specify the front part.
In the L model, the valgus-valgus motion axis in the scanning projection view of the ankle joint is used as the foot rear part of the zero-blur reference folding line. The position and orientation of the varus / valgus movement axis has a large difference such as individual differences due to race, gender, age, lifestyle, etc., and the distribution range seems to be large, but in the design of footwear etc. of one model number Assuming the average user image of the model number, the individual differences that vary considerably are divided to a certain extent. To identify.
As the zero blur reference line, a zero blur reference curve or a zero blur reference line may be used, or a zero blur trajectory actually measured using a foot pressure measuring device or the like may be used.

{{Description of the concept of standing at the average major axis angle α degrees}}
Further, the angle of the left and right feet is defined as an angle α degrees formed by the long axis 3 of the left and right scanning projections with respect to the body front direction line 19 in the scanning projection viewing in the constant speed straight walking motion. Is assumed to be mirror-symmetric. Since the angle α degree has a large individual difference as a walking habit, it is assumed that the L model is distributed in a range of plus 33 degrees (outer crotch walking) to minus 33 degrees (inner crotch walking) with one foot.
At the design stage of footwear and the like, this individual difference must be divisible and the angle in the average image must be assumed.
For the L model, think about the assumed average image of the footwear wearer;
The angle α degrees formed by the foot body front direction line 19 and the long axis 3 of one foot in scanning projection view is defined as an average long axis angle;
Standing with the long axis 3 of the foot in the scanning projection view facing the long axis 3 of the scanning projection view at the average long axis angle α degree with respect to the body front direction line 19 parallel to the body front direction center line 18 in the scanning projection view. “Stand at α degrees”.

In addition, in the L model type zero blur reference line specifying method, when specifying the zero blur reference curve or the zero blur reference broken line that is the base of the zero blur reference line for each of the left and right footwear, etc .;
In a state in which a wearer such as footwear stands at an average major axis angle α degree, it is specified to switch and harmonize the zero blur reference curve or the zero blur reference folding line of the left and right footwear.

{{Specific procedure for specifying the L model zero blurring reference line}}
FIG. 3 shows a specific method for identifying the zero blur reference folding line, which is the base of the zero blur reference line for each of the left and right footwear in the L model when the zero blur reference line is specified by the L model zero blur reference line specifying method. This will be explained based on.
In the L model, when the zero blur reference folding line is adopted as the zero blur reference line, the zero blur reference folding line specified by the method described here is applied. When the zero blur reference curve is adopted as the zero blur reference line, the zero blur reference curve specified based on the zero blur reference folding line specified by the method described here is used.
In the L model, the rear end of the long axis 3 of the foot in the left and right scanning projections when the average user wears footwear of a certain model number and stands at an average major axis angle α degrees A straight line segment having a length of 17 in the scanning projection view from the center to the head of the second phalanx is defined as a long-axis segment of each of the left and right footwear and the like as belonging to the footwear and the like side.
And in the L model, in the bottom virtual ground of each of the left and right footwear:
The midpoint 6 in the scanning projection view of the center of the two seed bones in the first metatarsal head of the foot is set as a reference point 6.
A straight line in the bottom virtual ground parallel to the long axis segment at a distance of 36% of the long axis segment length from the reference point 6 toward the inner side of the footwear etc. in the scanning projection view,
And a straight line in the bottom virtual ground parallel to the long axis segment at a distance of 14% of the long axis segment length from the reference point 6 toward the outer side of the footwear or the like in the scanning projection view,
And a straight line in the bottom virtual ground perpendicular to the long axis segment at a distance of 7% of the long axis segment length from the reference point 6 to the front side (toe side) of the foot in scanning projection view,
And a straight line in the bottom virtual ground perpendicular to the long axis segment at a distance of 41% of the length of the long axis segment from the reference point 6 to the rear side (heel side) of the foot in scanning projection view,
Starting from one of the refraction points 5 selected from the range surrounded by the four virtual straight lines in the bottom virtual ground;
In a state where a wearer such as footwear stands at an average major axis angle α degree with respect to a body front direction line 19 of the foot which coincides with or is parallel to the body front direction center line 18 in a scanning projection view;
An imaginary bottom portion that runs obliquely from the refraction point 5 toward the outer rear side at an angle of intersection β of any one selected from the range of 3 to 45 degrees in scanning projection view with respect to the long axis line segment A straight line in the ground;
A straight line in the bottom virtual ground that runs from the refraction point 5 toward the front outer side with an intersecting angle γ of (β-2α) degrees in scanning projection with respect to the long axis line;
Each of the left and right footwear that is left and right mirror-symmetrical with the footwear's long axis oriented at an average major axis angle α degrees (one leg) with respect to the body front direction line 19 Virtual line 1 of:
It is specified as the zero blurring standard broken line 1 for each of the left and right footwear.
In this way, in view of scanning projection, the zero blur reference fold line of the left and right footwear should be specified so as to switch and harmonize.
In the L model, the average major axis angle α degree is minus 33 degrees with respect to the market that walks on the outer crotch (plus) or the inner crotch (minus) on average depending on race and walking culture. Choose any one angle between ~ plus 33 degrees.

In the L model, the zero blurring reference curve 2 for each of the left and right footwear is specified as follows.
That is, for the zero blur reference curve 2, a sinusoidal arc along the zero blur reference folding line 1 in the scanning projection view is usually used. The zero-blur reference curve for left and right footwear etc. is deformed so that it becomes an arc of a sine curve in scanning projection view based on the zero-blur reference fold line specified in the above manner, and in harmony with switching, wearing footwear etc. It is preferable to specify the left and right footwear and the like so as to be curved in the scanning projection view such that the person becomes left-right mirror-symmetric when the person stands at the average major axis angle α degrees.
In addition, the zero-blur reference curve is a curved arc in which the zero-blur reference fold line is smoothly deformed along the zero-blur reference fold line in the scanning projection view. , Etc., may be approximated by substituting arcs of other similar curves.

The above is the L model type zero blurring reference line specifying method.
In designing the footwear or the like of the present invention, the zero blur reference folding line, the zero blur reference curve or the zero blur reference line should be specified by the specifying method.

{{Description of configuration of problem solving means}}
The configuration of the problem solving means will be described below.

{{Description of the operation of the footwear of the present invention, common part}}
Hereinafter, the operation of the above-described configuration of the present footwear will be described.
The present invention is an auxiliary tool for distinguishing ankle joint blur based on the L model. In other words, the present invention always includes a nuclear production line element that can distinguish the zero blur reference line as a reference line for controlling the locus of the bottom fulcrum from the peripheral part in the footwear or the like. Footwear.
It was an object of the present invention to make ankle joint blur distinctively controllable.
Because humans can sense the bottom fulcrum and bottom fulcrum trajectory, grasping the behavior of the foot based on the relative relationship between the bottom fulcrum and the zero-blur reference line distinguishes the ankle joint blur from the driver rolling of the ankle joint. I have already explained that.

If there is an auxiliary tool capable of distinguishing the zero-blur reference line, it becomes an auxiliary tool capable of distinguishing between driver rolling and ankle joint blur by comparing the bottom fulcrum and the zero-blur reference line. If it does so, it will become an auxiliary tool which can distinguish and control ankle joint blur.
In weight transfer movements, ankle joint blur affects the upper and lower limb joints from the foot to the upper;
As long as the auxiliary tool can distinguish the zero-blur reference line, the practitioner performs the weight transfer operation by trial and error in various patterns with respect to the base fulcrum locus with respect to the zero-blur reference line. It is assumed that the tool can easily learn control skills of ankle joint blur and upper / lower limb joint blur.
If so, in order to adapt the joint blur of the upper and lower limb joints according to the characteristics, purpose, and symptoms of the practitioner, the ankle joint blur can be flexibly distinguished and controlled to suit the characteristics, purpose, and symptoms. Become.

  Therefore, it is important to have a configuration that makes the zero blur reference line distinguishable in the auxiliary tool, and the auxiliary tool behaves in close contact with the foot during the weight transfer operation. It is preferable that

However, since the zero blur reference line is a virtual line, it is easy to forget and difficult to distinguish among the auxiliary tools.
Therefore, pay attention to the characteristics of footwear and the like that, once the practitioner wears it firmly, behaves while maintaining the spatial relative relationship with the ankle joint, where the ankle joint shake occurs, throughout the weight movement movement;
As the auxiliary tool, the present invention relates to footwear etc. that has produced a distinction line original that always includes a nuclear production line original that is a differentiator that makes the zero blur reference line distinguishable in footwear etc. It is a thing.

{{Explanation and supplementary explanation of the action of the footwear of the present invention in each aspect}}
Hereinafter, the operation of the configuration of the footwear of the present invention will be specifically described in order.

Referring to the example of FIG. 14, in the first aspect, the footwear of the present invention has the relationship between the zero blur reference line 33 specified by the L model zero blur reference line specifying method and the bottom fulcrum locus based on the L model. In order to make it easier for the wearer to grasp, the nuclear production line original body 9 devised so that the wearer can easily distinguish the zero blur reference line 33 from the peripheral portion 39 in the footwear etc. The discriminating line original body 35 included is produced on footwear or the like. In other words, the discriminant line original 35 composed of the members provided on the footwear or the like or the production line original 36 made of the drawn pattern is always set to the zero blur reference line 33 in the bottom virtual ground in the scanning projection view. A nuclear production line base 9 having a production line 34 representing the above is produced. The production line base body 36 has the production line 34 as the center line 11 and is arranged in one row intermittently as shown in FIG. 9A or one continuous member 37 as shown in FIG. 9B. A plurality of members 37 are used.
As shown in FIG. 11, the nuclear production line original body 9 has a production line 34 that is the center line 11 to which the zero shake reference folding line 1 or the zero shake reference curve 2 is applied.
The nuclear production line element 9 has a function of making the zero blur reference line 33 distinguishable in the footwear and the like for the wearer of the footwear and the like of the present invention. That is, the discriminant line source 35 makes the peripheral part 39 and the discriminant line source 35 distinguishable from each other by the difference in the attribute with the peripheral part 39 in footwear or the like, and distinguishes the zero blur reference line 33. Make it possible.
As a preparation for designing the footwear of the present invention in which the distinction line original 35 and the nuclear production line original 9 which are hardware are arranged, the zero blur reference line 33 must be selected and specified as software. Regardless of whether the zero blur reference line 33 is the type of zero blur reference broken line 1 or the type of zero blur reference curve 2, the zero blur reference line 33 is selected and specified from the range defined by the L model zero blur reference line specifying method described above. Should. Selection and specification of the type of the zero blur reference line 33 may be freely selected on the design as long as it is based on the L model.
The feature of the footwear of the present invention is that the zero blur reference line 33 selected and specified from the range defined by the L model type zero blur reference line specifying method is embodied as the nuclear production line original body 9, The distinction line element 35 that necessarily includes the line element 9 is to be produced on footwear or the like. Therefore, the discriminant line original 35 has the effect of making the zero blur reference line 33 distinguishable from the peripheral portion 39 in the footwear of the present invention.
Therefore, the footwear of the present invention functions as an auxiliary tool capable of distinguishing the zero blur reference line 33 and functions as an auxiliary tool capable of distinguishing and controlling ankle joint blur.

In the second, third, and fourth aspects, the footwear of the present invention is the first aspect,
Different places such as footwear are selected as places where the distinction line original 35 is produced.
That means
In the second aspect, the sole contact portion (insole or insole in shoes) 38 such as footwear is selected as a place where the distinction line original body 35 is produced. For example, in FIG. 8A, the production line original 36 constituting the distinction line original is provided.
In the third aspect, the production line original 36 is produced on the ground contact part (outsole part or ground contact part) 13 such as footwear as a place where the distinction line original 35 is produced. For example, in FIG.8 (c), the production line original body 36 which comprises a distinction line original body is produced.
In the fourth aspect, an intermediate layer (in the case of shoes, a midsole part) 12 sandwiched between a sole contact part of footwear and the ground contact part is selected as a place where the discriminant line original body 35 is produced. is there. For example, in FIG.8 (b), the production line original body 36 which comprises a distinction line original body is produced.
By doing so, in the footwear etc. of the present invention of any of the second to fourth aspects, the discriminant line always including the nuclear production line element 9 produced in each of the above-mentioned places of the footwear etc. The line element 35 has the effect of making the difference between the peripheral part 39 and the distinction line element 35 distinguishable from the peripheral part 39 by the sense of feeling of the sole, and the zero blur reference line 33 is set. It has the effect of making it distinguishable. Here, the nuclear production line element 9 is a kind of the production line element 36.
For example, assuming that FIG. 7 represents a bottom portion of footwear or the like, that is, a sole contact portion 38 or a ground contact portion or an intermediate layer in a scanning projection view, as shown in FIG. The body 9-C or the core production line base 9-A based on the zero blurring reference curve 2 is installed at the corresponding locations of the footwear of the present invention of the second to fourth aspects.

In the fifth aspect, the footwear of the present invention is any one of the second to fourth aspects.
The difference in attribute between the production line original 36 constituting the distinction line original 35 and the peripheral part 39 is set as the hardness difference as described above, and the production line original 36 is made of a material harder than the peripheral 39. The discriminant line original body 35 provided is selected.
That is, the distinction line source 35 that necessarily includes the nuclear production source element 9 provided in the sole contact part of the footwear or the intermediate layer or the ground contact part is an attribute difference with the peripheral part 39. Due to the hardness difference, an effect of making the peripheral portion 39 and the distinction line original 35 can be distinguished and an effect of making the zero blurring reference line 33 distinguishable are brought about.

In a sixth aspect, the footwear of the present invention is any one of the second to fourth aspects.
The difference in attributes between the production line element 36 constituting the distinction line element 35 and its peripheral part 39 is an uneven difference,
The production line base 36 is continuous from the peripheral portion 39 as shown in FIG. 9 (a) or intermittently as shown in FIG. 9 (b), and a protrusion or a figure as shown in FIG. 10 (a). As shown in FIG. 10 (b), the discriminating line element 35, which is an array of the indigenous line elements 36 that are depressed and provided, is selected.
That is, the distinction line source 35 that necessarily includes the nuclear production source element 9 provided in the sole contact part of the footwear or the intermediate layer or the ground contact part is an attribute difference with the peripheral part 39. The unevenness difference provides the effect of making the peripheral portion 39 and the distinction line source 35 distinguishable, and the effect of making the zero blur reference line 33 distinguishable.
The height of the projection-type production line base 36 need not be uniform. Since the sole rigidity is different between the part that covers the bones of the foot and the part that covers the muscles and tendons, the part where the soles are high has a low height of the production line base 36 and the part where the soles have low rigidity. The reverse is also possible.

In the seventh aspect, the footwear of the present invention, in the first aspect, has
As shown in the example of FIG. 6, a distinction line element that is provided on the upper covering portion 4-B of footwear or the like and always includes the produced nuclear production element 9-B. In FIG. 6, a member 37 (FIG. 9) in which the production line original forming the nuclear production line original 9-B alone is formed is an arbitrary shape of the production line original. (A)) or a plurality of members 37 (FIG. 9 (b)) of arbitrary shape provided in an intermittent arrangement, or one drawn pattern 37 (FIG. 9 (a)) of arbitrary shape. Or a plurality of arbitrarily shaped patterns 37 (FIG. 9B) drawn intermittently. The difference in attribute from the member or the peripheral portion 39 of the pattern is a color difference. If the color difference is clear, any color can be used as long as the color can be distinguished from the surrounding colors, as requested by the design design. When there are a plurality of lines, the colors of the production line original may be different.
Due to the color difference with the peripheral portion 39 of the core production line element 9-B among the distinction line element elements produced on the upper covering part of footwear etc., the distinction line element element is the The effect of making the zero blur reference line indistinguishable from its periphery is provided.

  In any of the first to seventh aspects, the footwear of the present invention can be distinguished from the core 39 of the nuclear production line main body 9 centering on the zero blur reference line 33 in the footwear of the present invention. Since the wearer can separately detect the bottom fulcrum / bottom fulcrum locus with his / her foot, the relationship between the bottom fulcrum / bottom fulcrum locus and the zero blur reference line 33 can be compared. And ankle joint blurring can be distinguished from driver rolling. Therefore, the footwear of the present invention acts as footwear that makes it possible to distinguish ankle joint blur from driver rolling.

In an eighth aspect, the footwear of the present invention is in any one of the fifth to sixth aspects;
The production line element constituting the distinction line element is a continuous combination structure or a flexible body composed of a woven belt;
By making the flexible body into a flexible body containing at least one kind of elastic material having a Young's modulus (rigidity) of any one value selected from the range of 0.1 to 216 GPa, the peripheral portion 39 The flexible body can be selected as a material that is difficult to stretch (difference in Young's modulus), and if the foot is rolled or kept flat by stepping on the flexible body, the sole presses and restrains the flexible body. In addition, it is possible to reinforce the ability to mitigate the landing impact of the foot by restraining the elongation of the bottom side of the inward-side longitudinal arch of the foot that protrudes upward and passes almost directly above the flexible body.
Further, at least the nuclear production line original (the flexible body) to be produced is selected so that the Young's modulus of the peripheral portion 39 is set to have the Young's modulus difference within the above range, whereby the difference in Young's modulus ( The difference in rigidity) makes it possible to distinguish between the peripheral portion 39 and the nuclear production line element, and to make the zero blur reference line distinguishable.

In a ninth aspect, the footwear of the present invention is in the eighth aspect;
Footwear or the like in which the flexible body is replaced with a shank composed of a distinction line element composed only of a nuclear production line element.
The shank is:
A shank 9-D having a center line bent downward in a side view and having a center line 11 overlapping the zero blur reference curve 2 in a scanning projection view;
Shank 9-D as shown in FIGS. 12 (a), (e), (f), and (g), a part of a round bar (not shown), or a strip-shaped shank 9- Because D:
The shank 9-D acts as a spring.
The strip-shaped shank 9-D is, for example, a twisted strip shape as shown in FIGS. 12 (a), (b), (c), and (d), or a strip twisted in the reverse direction shown in the figure. It may be a shape (not shown) or a non-twisted strip (not shown).
In addition, since the material is an elastic material, a material having shape memory and restoring properties can be selected for the shank, and it is preferable to do so.
When the bottom fulcrum is traced to the center line 11 in the scanning projection view of the shank 9-D, which is the core of the nuclear production line, the ankle joint blur becomes zero;
In addition, the shank 9-D becomes a downwardly convex bow-shaped spring, reinforces the landing impact mitigation ability of the upper side arch foot of the convex foot passing above the shank, and the spring Restoring power helps to advance the foot. By selecting a material in the range of Young's modulus described in the eighth aspect, the bending rigidity (Young's modulus) of the shank 9-D can be selected as being larger than the peripheral portion 39, and the shank is rigid. It becomes distinguishable from the peripheral part 39 by the difference.
The shank 9-D is mechanically regarded as a three-dimensional bent beam. When the bottom fulcrum is placed on the shank 9-D as a bending beam, the bending beam generates not only the vertical deflection but also the spring reaction force of the torsion of the beam. That is, the shank 9-D can be designed so as to generate a spring reaction force of twisting in the varus direction at the front part after being distorted by receiving a landing impact at a part corresponding to the rear part. When this is considered in the weight movement operation of the forward walking, the shank 9-D gives the foot a force that converts the vertical force due to the body weight into the forward force and assists the foot. Further, if the weight transfer operation is performed with the bottom fulcrum placed on the shank 9-D, the shank 9-D has high rigidity, so that the leg is guided to assist the L model type weight transfer operation with zero ankle joint blur, It works to make your feet easier.
In addition, the shank 9-D is an impact mitigating material that mitigates the impact at the time of landing by the upward and downward spring action due to the downwardly convex arch shape, and the shank 9-D has a foot located on the shank. Helps to reduce the impact of the inner longitudinal arch, so it works as a foot fatigue reduction tool.

In a tenth aspect, in the footwear of the present invention, in any one of the fifth to ninth aspects except for the seventh aspect;
Front and rear by a distinction line element 35 composed of a continuous type of production line element (36 in FIG. 9A) and a reinforcing belt 10 provided on the upper covering portion 4-B. A frame surrounding the entire shoe such as footwear is formed in the vertical direction.
The frame (10 and 35) includes an end in the toe direction (front end of footwear, etc.) 16-A, an end in the heel direction (back end of footwear, etc.) 16-C, and At the three points of the boundary 16-B of the front part of the foot and the rear part, they are joined together vertically or facing each other (if the distinction line element is produced on the sole contact part 38, it is joined with the reinforcing belt 10). The distances in the scanning projection view of the front part and the rear part of the distinction line original 35 are constrained by the movement of the upper and lower sides of the frames (10 and 35) being different and may be merely facing each other. Since it is restrained from stretching, the sag deformation of the inner vertical arch of the foot passing over the nuclear production line element in the distinction line element 35 is suppressed, and the weight movement movement for a long time is suppressed. It works to reduce foot fatigue caused by.

Regarding the characteristics of the footwear of the present invention, such that the original discriminating line has the effect of making the zero-blur reference line distinguishable from its periphery in the footwear of the present invention;
The footwear of the present invention in the eighth aspect has such characteristics due to the difference in Young's modulus between the discriminating line element and the peripheral part 39 that always include the nuclear elemental line element that has been erected;
The footwear of the present invention in the ninth aspect has the characteristics inherited from the footwear of the present invention in the eighth aspect;
The footwear of the present invention in the tenth aspect has the characteristics inherited from the footwear of the present invention in the fifth or sixth aspect;
Each has its characteristics.

Therefore, since the footwear of the present invention of any of the first to tenth aspects is provided with the discriminant line original 35 having the attribute difference from the peripheral portion 39, the zero blur reference line 33 is set by the difference. It can be distinguished. Therefore, by comparing the positional relationship between the bottom fulcrum / bottom fulcrum locus and the zero blur reference line 33, ankle joint blur can be distinguished from driver rolling.
Accordingly, the footwear of the present invention functions as an “auxiliary tool for distinguishing ankle joint blur that can distinguish ankle joint blur from driver rolling” as a problem to be solved.

{{Explanation of effects of footwear of the present invention}}
Since humans have a low ability to recognize three-dimensional space, they have a weak point that it is extremely difficult to recognize a zero-blur reference line that moves in accordance with the complicated three-dimensional movement of the foot during weight movement. The footwear of the present invention has an effect of filling in the weak point because the zero-blur reference line as a reference line for controlling the locus of the bottom fulcrum can be distinguished from the peripheral portion in the footwear that behaves together with the foot.

That is, the footwear of the present invention of the first to tenth aspects are all;
Ingenuity to produce a three-dimensional shape such as footwear or the like, or a distinction line source that always contains a nuclear production line source at the bottom, such as footwear, by scanning projection into the bottom virtual ground. By doing so, you can understand the zero blur reference line as if it were close to the line drawn on the ground;
In addition, the zero blur reference line can be grasped in real time even during weight transfer movements;
In addition, it is possible to distinguish ankle joint blur from driver rolling by comparing the base fulcrum / bottom fulcrum trajectory that can be originally detected and the zero blur reference line;
It has the effect of making ankle joint blur controllable in real time during weight movement.

  As a result, it can be said that any of the footwear of the present invention has a particularly suitable function as an auxiliary tool for distinguishing ankle joint blur.

  Further, as a result, the footwear of the present invention can flexibly control the joint blur of the upper and lower limb joints according to the practitioner's own characteristics, purpose, and symptoms. As a result, it is possible to adapt joint blurring of the upper and lower limb joints according to the characteristics, purpose, and symptoms.

  In other words, all of the footwear of the present invention has the effect of making it easier to acquire ankle joint shake control skills than before, and as a result, adapts various joint shakes of the upper and lower limb joints according to characteristics, purposes, and symptoms To make it easier than conventional footwear. For example, by adapting the joint blurring of the upper and lower limb joints, there is an effect of enabling prevention / correction of hallux valgus / knee pain, control of body orientation, and the like.

  In addition, the nuclear production line original body produced in the footwear of the present invention has zero ankle joint blur, increases the running stability of the footwear during weight movement, and reduces deformation of the footwear. Has the ability to provide guidelines, reduce foot fatigue.

Further, as a conventional walking method, there is a walking method that does not pay attention to ankle joint blur and knee joint blur.
As another conventional gait style, the ankle joint joint and knee joint brace of the base fulcrum goes from the center of the buttocks to the outer side of the middle foot and then through the thumb ball to the toe. A dynamic walking method that utilizes the gait is also widely used.
Walking as an L model type body weight movement operation is different from the conventional manner of walking because there is no ankle joint blur and the resulting knee joint blur.
However, the footwear of the present invention, which is an auxiliary tool capable of distinguishing and controlling ankle joint blur and driver rolling, can flexibly control ankle joint blur and knee joint blur. It has the effect of making it easy to learn various ways of walking.

Furthermore, in an eighth aspect, the footwear of the present invention is;
A normal rubber is selected by selecting the elastic material having the Young's modulus of any one of the numerical values selected from the range of 0.1 to 216 GPa as the flexible body that is the discriminant line element, and including at least one kind. You can choose one that has higher bending and tensile stiffness than the material, that is, higher Young's modulus;
Since the distinction line element becomes difficult to be pulled and deformed, the arch curvature of the inner side vertical arch of the foot passing over the nuclear production line element is reduced, and the reduction of the impact relaxation ability of the foot is reduced, Has the effect of reducing foot fatigue.

Further, in the footwear of the present invention in the ninth aspect, the weight is easily moved by putting the weight on the stiff shank. Therefore, the footwear of the present invention is applied to the L model type weight shifting operation in which the shank has zero ankle joint blurring. This has the effect of guiding the wearer.
The footwear of the present invention in the ninth aspect also has a vertical curvature that is easy to roll in three dimensions, and the shank rolls on the sole because it acts as a spring. Easy to walk.
Furthermore, the footwear of the present invention according to the ninth aspect reinforces the impact mitigation ability of the inner longitudinal arch of the foot passing over the shank so that there is less fatigue on the foot and less impact on the upper and lower limb joints. Etc. can be provided.

  Furthermore, in the tenth aspect, the footwear of the present invention has a frame structure that surrounds the entire shoe such as footwear restrained at three points in the vertical direction by the reinforcing belt provided on the distinction line original and the upper covering portion of the footwear. Therefore, when attached to the foot, the distance between both ends in plan view of the discriminant line source body is restrained by the frame and it is difficult to stretch, so the inner side of the foot passing over the discriminant line source body It has the effect of reducing the arch curvature of the vertical arch and reducing the fatigue of the foot and the reduction of impact relaxation ability.

  Control of the movement of the bottom fulcrum / bottom fulcrum trajectory in the bottom virtual ground is nothing but control of weight shift (that is, body centroid shift). Therefore, the footwear of the present invention makes it possible for the practitioner to grasp the relationship between the weight shift and the zero blurring reference line, and is extremely vague and difficult to understand. It has the effect of making the weight transfer control method specific and easy to understand.

Inappropriate ankle joint blur caused by weight shift causes joint blur in each of the upper and lower limb joints, and the lateral contact / overload burden on the joint surface is weak, not the original joint surface Causes damage and deformation, such as unilateral reduction, in the joints of the part, leading to hallux valgus, knee and hip osteoarthritis. From the aspect of preventing and correcting the damage / deformation, flexibly adjust the joint blurring of the upper and lower limb joints according to the characteristics of various practitioners and the purpose of which joint you want to prevent or correct. In order to adapt, all of the footwear of the present invention has the effect of making it possible to flexibly control ankle joint blur according to the characteristics, purpose, and symptoms of the practitioner.
Also, in sporting situations, the footwear of the present invention is all expressed in the form of knee shake, hip joint shake, body shake, eye shake, etc. flexibly and powerfully according to the characteristics and purposes of various practitioners. This has the effect of making controllable to reduce or increase each joint blur (including ankle joint blur) of the upper and lower limb joints.

In particular, in the footwear of the present invention in the sixth aspect, footwear and the like produced by projecting the production line original constituting the distinction line original continuously or intermittently from its peripheral portion 39 Then;
In reflexology (a kind of manipulative technique), if you apply high pressure, the reflex zone (acupuncture point) that is said to work for high blood pressure, stiff shoulders, rheumatism, diabetes, constipation, and strokes happens to coincide with the zero blur baseline. Exists. Therefore, the footwear and the like of the present invention in which the production line original body having a protruding shape compared to the peripheral portion 39 has a secondary effect that a strong pressure effect on the reflection zone (acupuncture point) can be obtained. .

The footwear of the present invention is obtained by applying the technology of the present invention based on the L model to them.

The footwear of the present invention includes an instep covering portion including a part covering the entire instep side of the wearer's foot, a sole contact portion (such as an insole or an insole) in contact with the sole / sock and / or a bottom portion of the footwear, etc. An intermediate layer (midsole) of the bottom part of footwear or the like that is disposed below the sole contact part and / or bonded to the upper surface of the ground contact part (a ground contact part such as an outsole or a sock) that is in direct contact with the ground have. Insole, midsole and outsole are commonly used in the shoe industry.
Also, the sole contact portion (insole or insole) may be built into shoes, replaceable as a genuine part of the shoe, or the sole contact portion may be separately manufactured and sold separately.
Further, the footwear of the present invention is;
As in the type of wear such as socks, there is no structure corresponding to the middle layer of the bottom such as footwear and / or the ground contact portion of the bottom of the foot contact and the bottom of the footwear and the middle layer of the bottom of the footwear merged. Some are composed;
Moreover, the opening part may be large and the way of covering may be incomplete, such as sandals, clogs, and high heels.

  The distinction line source 35 that includes the core production line element 9 and includes the production line element 36 is a sole contact part 38 (insole or insole) of footwear or the like, or a bottom part (intermediate layer 12, Or it is preferable to produce in the ground contact part 13) or the instep covering part 4-B.

In designing the size model of the footwear of the present invention;
From the numerical range specified in the above-mentioned L model type zero blurring reference line specifying method, selecting an average model of individual differences among user groups of a certain model number according to race, gender, age, and body shape, the L model According to the zero blur reference line identification method, the zero blur reference folding line should be identified, or the zero blur reference curve should be identified based on the identified zero blur reference folding line, and the zero blur reference line should be identified therefrom. However, this is not the case when the zero blur reference line is specified from the actual measurement value.
In other words, the zero blur reference line that is the base of the distinction line original body / nuclear production line original body to be produced in the footwear of the present invention in any one of the first to tenth aspects is the L model type zero blur reference line. It should be identified based on the line identification method. The zero blur reference line may be specified from the actually measured zero blur locus.

For each of the left and right footwear, etc., the discriminating line source should always be composed of at least one, and at most five production line bases including the nuclear production line base.
The production line original is distinguishable from the peripheral part 39 in the scanning projection view as a production line overlapping with the zero blur reference line due to a difference in attributes between the production line original and the peripheral part 39 in footwear or the like. As described above, it is one continuous member or a plurality of members or patterns intermittently arranged in a row. The center line in the scanning projection view of the nuclear production line element should be designed to overlap the identified zero blur reference line.
The member and the pattern described in the footwear of the present invention in each aspect may be in any shape as long as they can be distinguished from the peripheral portion as the production line original in the footwear.
As the member, usually, a strip shape, a rod shape, an elongated plate shape, a plurality of shapes arranged intermittently in a row can be distinguished in footwear, etc., so the cross section of the member is arbitrary. However, usually, a member having a rectangular cross section, a circular / elliptical tube, a partial cross section of a circle / ellipsoidal cylinder, or a single or combined cross section obtained by breaking them is usually used.

Since the pattern is drawn, the type of color of the pattern may be arbitrary, but it is preferable that at least the nuclear production line element (pattern) has a clear color difference from the surrounding colors. Different colors may be used for each production line element (pattern), but each color has a color difference with the surrounding color, and it is particularly preferable to highlight the color of the nuclear production line element (pattern). .
In particular, in the footwear of the present invention in the seventh aspect, the discriminant line original is produced on the upper covering part of the footwear etc., but the discriminant line original is constituted from the design design requirements of the footwear etc. There may be multiple production line bases, including nuclear production line bases.

  The width and length of each production line base, such as the left and right footwear, and the dimensions of the height or depth except for the case of drawing are selected within the range described in the footwear of the present invention in the first aspect. It should be specified and produced in footwear.

In any of the footwear of the present invention, as a method of producing the discriminating line original body / nuclear production line original body in footwear, etc., the original body of the continuous or intermittent member type is left and right for the purpose of industrial use. There are a method of providing each of the footwear and / or a method of drawing the original of the continuous or intermittent pattern type on each of the left and right footwear for industrial use. For these methods, it is sufficient to use a well-known, publicly known or publicly known manufacturing method such as footwear.
For example;
Representative examples of the manufacturing method for providing the base material of the member type include sewing, sticking, fusion molding, adhesion, injection molding, heat vulcanization, hot melt adhesion, etc. Well-known, publicly known and publicly used manufacturing methods are used;
Representative methods of drawing the original of the pattern type include well-known, publicly known, and publicly known manufacturing methods such as weaving, dyeing, fusing, spraying, printing, handwriting, etc. Is used.

For example, materials (including iron, steel, various alloys), plastic strips, plates, rods, rubber, urethane foam, urethane, EVA, nylon, foam rubber, Contains at least one of natural fiber / artificial fiber fabric, natural leather, high-strength fiber such as carbon fiber, Kevlar fiber, aramid fiber, polyester fiber, glass fiber and metal wire, or their woven fabric / combination structure The material is preferably a material selected in consideration of differences in attributes such as differences in hardness and Young's modulus from the surrounding material.
The color pigments used in the pattern type production line element may be freely selected as long as they have durability and weather resistance and can distinguish the color from the peripheral color.

  As the peripheral part of the production line original material, materials and configurations known, publicly known, and publicly known in the art may be used in the same manner as ordinary footwear and the like.

  In the footwear of the present invention in the eighth or ninth aspect, an elastic material having a Young's modulus of any one value selected from the range of 0.1 to 216 GPa is used. For example, as the elastic material, It is a material containing at least one of shape memory alloys or metals such as steel, resins with high Young's modulus such as polyurethane resin, polyamide resin, polycarbonate resin, cork, rubber, etc., and hardness with peripheral material -It is preferable that the material is selected in consideration of attribute differences such as Young's modulus differences.

  In particular, in the footwear of the present invention according to the ninth aspect, since the shank material is preferably a material with no shank, a shape memory alloy or a metal having a strong shape memory property or elastic resilience such as steel, Or in the case of a resin material, the material with shape memory property, or those combination is preferable.

In the footwear of the present invention in the tenth aspect;

For example, referring to FIG. 13, the frames (10 and 35) include the toe-direction end 16-A, the heel-direction end 16-C, and the forefoot foot of the distinguishing line original. At the three points of the rear boundary 16-B, they are joined vertically or face each other.
Further, in the footwear of the present invention in the tenth aspect, the continuous footing provided in the upper covering portion of the footwear of the present invention in the seventh aspect is also used as the footwear in the seventh aspect. The production line element constituting the distinction line element of one member type can be used as a belt type member, and can also serve as a reinforcing belt provided on the upper covering portion of the footwear of the present invention in the tenth aspect. In this case, two distinction line originals are provided at the bottom of the footwear or the like and the upper covering.
The material of the reinforcing belt 10 may be a known or publicly used reinforcing belt material that is usually used for shoes.

{{Individual description of each embodiment of the invention}}
Hereinafter, typical examples will be described.

The embodiment shown in FIG. 1 is a combination of the shank 9-D described in the ninth aspect of the present invention footwear and the reinforcing belt 10 described in the tenth aspect of the present invention footwear, etc. 1 is an embodiment of the present invention footwear or the like in which a frame surrounding footwear and the like is formed in the up and down and front and rear directions by a reinforcing belt 10. In the frame, the shank 9-D and the reinforcement belt 10 are joined at three points, that is, a footwear tip 16-A, a foot front-foot rear boundary 16-B, and a footwear rear end 16-C.
As an example of the reinforcing belt 10, there is the reinforcing belt 10 illustrated in the side view from the outer side in FIG. The shank may be provided on any of the sole contact portion such as footwear, the intermediate layer, and the ground contact portion.
In this embodiment:
The difference in Young's modulus (rigidity difference) between the shank and the surrounding area makes the zero blur reference line distinguishable, and the ankle joint blur distinguishable from the driver rolling. Not only becomes controllable;
The frame preferably works in terms of reducing landing impact and reducing foot fatigue.
That is, the shank;
Since it is an elastic body having a center line that is bent downward in a side view, it acts as a downward bow-shaped spring and passes through the shank above the shank. The ability to relieve the landing impact of the foot of the arch is reinforced, and the restoring force of the spring has an effect of assisting the advancement of the foot, so that it works preferably in terms of reducing the fatigue of the foot.
In addition, it is preferable to select a material having a shape memory property and a restoring property as the shank material.

The embodiment illustrated in FIG. 13 is an example of the footwear of the present invention of the tenth aspect.
In this example:
A distinction line element 35 consisting of a continuous type of production line element (for example, 36 in FIG. 9 (a)), a footwear-like tip 16-A, a boundary 16-B between the front part and the foot part, A reinforcing belt 10 provided on the upper covering portion 4-B joined at three points of the rear end 16-C of footwear or the like;
The distinction line original 35 is provided on the intermediate layer 12 (midsole) of the shoe sole.
The reinforcement belt 10 has an opening through which the ankle passes through the upper covering portion 4-B of footwear or the like, so that the ankle portion is bypassed. In this way, the frame (35 and 10) is formed which is joined to the distinction line original body 35 and surrounds the entire shoe such as footwear in the front-rear and vertical directions.
The reinforcing belt 10 restrains the length of the front part and the rear part of the distinction line element 35 from extending in the scanning projection view, so that it passes over the distinction line element 35 by chance. Sag deformation of the inner vertical arch of the foot is suppressed, reducing fatigue of the foot due to prolonged weight movement.
In addition, the difference between the attributes of the production line element 36 constituting the distinction line element 35 and the peripheral part 39 makes the zero blur reference line distinguishable, and ankle joint blur can be distinguished from driver rolling. Finally, it becomes possible to control joint blurring of the upper and lower limb joints.

In the embodiment shown in FIG. 7, the nuclear production line element 9 -C based on the zero blurring standard folding line 1 or the nuclear production line element 9 -A based on the zero blurring reference curve 2 is the footwear as the nuclear production line element 9. Etc.
FIG. 7 shows a scanning projection view of FIG. 8 (a), (b) or (c).
As illustrated in FIG. 8A, FIG. 8B, or FIG. 8C, the nuclear production line original 9-C or the nuclear production line original 9-A as the production line original 36 is the sole of the foot. The contact portion 38 or the intermediate layer 12 or the ground contact portion 13 can be provided.
Further, for example, when viewing FIG. 7 as a diagram showing the inner sole of the sole contact portion 38 in the scanning projection view, the inner sole 4 which is the illustrated footwear of the present invention is the footwear of the present invention in the sixth aspect. If it sees that the example of this will be represented, the projection of the nuclear production line original 9-C or the nuclear production line original 9-A as a projection type production original (36 in FIG. 10A) The height may not be uniform. The part of the sole that covers the foot bones and the part of the muscles / tendons has a different rigidity, so that the soles have a high rigidity so that they can be easily detected. May be reversed if the sole stiffness is low. The protrusion-type nuclear production line element may be a plurality of intermittent protrusion-type production line elements 36 as shown in FIG. 9B.
Also, the zero blur reference line can be distinguished by the difference in protrusion between the nuclear production line source constituting the distinction line source body and its peripheral portion 39, and ankle joint blur can be distinguished from driver rolling. Finally, it becomes possible to control joint blurring of the upper and lower limb joints.
In addition, in foot reflexology (a kind of manipulative technique), if you apply high pressure, the reflex zone (point) of the sole that is said to work for high blood pressure, stiff shoulders, rheumatism, diabetes, constipation, and strokes happens to be along the zero blur baseline. In order to increase the effect of strong pressure, it is preferable that the nuclear production line element is provided on the sole contact portion 38. In this case, cork or the like may be used as the material for the sole contact portion.

The footwear of the present invention illustrated in FIG. 6 is an example of the footwear of the present invention in the seventh aspect.
As shown in the example of FIG. 6, a member is provided or a pattern is drawn on the upper covering portion 4-B of footwear or the like as a distinction line original consisting only of the nuclear production line original 9-B. Footwear, etc.
The difference in attribute from the member or the peripheral portion 39 of the pattern is a color difference, and it is preferable that the color difference is clear in order to distinguish the zero blur reference line. FIG. 6 shows an embodiment in which a nuclear production line original 9-B is produced as the distinction line original 35.
Any color can be used as long as it is a color that can be distinguished from surrounding colors as requested by the design design. In addition to the nuclear production line element 9-B, there are a plurality of production line elements. If it is necessary to provide or draw a book, it can be arbitrarily produced within 5 ranges. Further, the colors of the plurality of production line bases may be different from each other.
The zero blur reference line in the footwear etc. of the present invention is determined by the color difference with the peripheral portion 39 of the core production line element 9-B in the distinction line element element provided on the upper covering part of footwear etc. It is distinguishable from the peripheral part.

The embodiment and the example of the present invention have been described above.
