Japanese Patent Laid-Open No. 2000-102553
In sports and the like, many support devices for protecting various joints including feet and ankles are widely used. The support device is attached for the purpose of reinforcing and protecting the weak point of the body. In recent years when sports medicine has developed, supporters who assist weak points when playing sports have become indispensable.
Supporters are often attached to joints with a large amount of exercise, such as elbows and knees, and are recognized as auxiliary devices for protecting yourself from sprains and broken bones. Further, even when an injury such as a sprain has occurred, it is used as an auxiliary device for fixing a joint or the like for the purpose of assisting the movement of the damaged part during treatment.
[0004]
In recent years, there are an increasing number of people who go on a diet or jogging to build strength, but most often run on asphalt paved roads. Exercise such as jogging itself is good for the health, but the road that runs is paved with asphalt, which increases the burden on the ankle, causing problems. It is conceivable to exercise only on soil or turf where asphalt is not paved, but because there are few such places, it is currently necessary to exercise on asphalt. In particular, sprains, contusions, and injuries of ankle joints are known as the most frequently damaged parts of human joints. Therefore, supporters are widely used in general to protect joints such as ankles from injury.
In addition to sports, support equipment may be used to prevent joint pain in the elderly.
[0005]
As a conventional technique, for example, an invention of “ankle joint orthosis” (Japanese Patent Laid-Open No. 2000-102553) is disclosed. The invention disclosed in this application is hinged to the lower body of the elastic main body, the side strut plate made of a hard material, the front shell portion made of a hard material, and the left and right side strut plates. It is composed of a lower side strut member and a sole belt configured to connect across the sole from one lower side strut to the other lower side strut, but the sole belt made of a hard material is The presence on the sole of the foot has a bad feeling of wearing, and there is a disadvantage that the sole of the foot becomes uncomfortable during exercise.
In addition, a device that has been provided with a fixed part on the side and a plate-like or belt-like member that acts as a trender on the sole has been developed, but it is a comfortable and efficient support device that does not feel uncomfortable on the sole. Etc. was a problem to develop.
[0006]
The applicant of the present invention has developed the support device disclosed in Japanese Patent Application No. 2002-103022, “Support Device”. This support device includes a fixing part that protects the ankle, a trunk that is attached to the leg and separated to the left and right and connected at the center with a stretchable fiber, and a hinge that pivotally connects the fixing part and the trunk. The exterior simple artificial joint consisting of the above is equipped on the supporter body, and the ankle is firmly fixed to protect it from sprains of external rotation and internal rotation. However, since the support device having this configuration has a configuration in which the trunk made of a hard material extends to the sole, there is a drawback that pain occurs in the trunk on the sole when walking or performing various exercises. Moreover, since there are many component parts, there also existed a problem of taking time and effort for mounting | wearing. In addition, there is a problem in that the stretchable fiber serving as a flexible trender to which the left and right trenders are bonded may break due to friction, has poor durability, and cannot obtain a sufficient fixing effect.
Therefore, the applicant has developed a support device for solving the above-mentioned problems and has led to the creation of the present invention.

DETAILED DESCRIPTION OF THE INVENTION
In the following, the support device according to the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view of the support device of the present invention, FIG. 2 is a central sectional view of the embodiment of FIG. 1, and FIG. 3 is a central sectional view of another embodiment. 4A and 4B are side views of the trunk, and FIG. 4C is a bottom view of the storage protection unit. FIG. 5 is a central sectional view of still another embodiment of the present invention.
As shown in FIG. 1, the support device 10 according to the present invention includes a supporter body 20, a pair of fixing parts 30 and 31, trenders 40 and 41, hinge parts 50 and 51, a bag-like storage protection part 60, and the like. , And a band unit 70.
[0012]
The supporter main body 20 is formed of a sock-shaped cylindrical body without a toe and a toe made of a flexible material that covers the entire ankle. As shown in FIG. 1, the supporter body 20 is formed of a cylindrical body with corresponding portions cut out so that the toes and heels are exposed when worn, and extends and contracts to cover the entire foot and ankles except for the heels and toes. It is a cylindrical body made of a material with excellent properties. The supporter body 20 covers the entire joint part of the foot and ankle that are easily injured when worn, thereby reliably holding the foot and ankle and reducing the burden on the joint.
[0013]
The material of the supporter body 20 can be replaced with a non-stretchable material, but it is inconvenient at the time of wearing, and since it has an emphasis on exerting the supporter function by closely contacting after wearing, it has elasticity. It is desirable to select the material.
The surface of the material of the supporter main body 20 can also be composed entirely of a male or female surface fastener material (for example, a loop surface or a hook surface material) that can be joined to a surface fastener provided on a trainer described later. .
[0014]
The fixing portions 30 and 31 are a pair of left and right members made of a hard material curved in an arc shape that covers the ankle of the leg from both sides from above the supporter body. As shown in FIG. 1, it is a substantially rectangular member that is slightly curved in an arc shape that covers the ankle of the leg from both sides, and is formed in an arc shape so as to match the shape of the ankle. The fixing portion and the supporter main body are attached to the leg by a band portion 70 described later above the ankle. Since the shape of the ankle is different (or symmetric) depending on the left and right of the leg, the pair of fixing portions has a substantially symmetric shape depending on the left and right of the leg. Further, the fixing portions 30 and 31 are configured to be swingably engaged with a later-described trainer 40 via a bearing, and are provided with a recess having the same shape as the washer and the bearing so as to engage with the bearing. In addition, a long hole that engages with the bearing is formed in the recess. The long hole is larger than the bearing so that the hinge portions 50 and 51 can swing, and has a structure that is laterally long. In order to securely fix the ankle, in this embodiment, a plastic material is used for the fixing portions 30 and 31. However, any material other than a plastic material can be used as long as it has a hardness that can fix the ankle.
[0015]
As shown in FIG. 1, the trunks 40 and 41 are a pair of left and right members 40 and 41 having tips in the storage protection part from the vicinity of the ankles of the legs along the shape of the foot, and the upper part of the trunk is swingable by the hinge part. It is the structure engaged with the fixing | fixed part. An adhering portion 42 is provided on the side surface of the lower part of the trunk, and the adhering portion is configured to be joined to an adhering adhering portion 62 inside a bag-shaped storage protection portion 60 described later. In the embodiment shown in FIG. 1, the fixing portion 42 is provided on the outer side surface, but in the embodiment shown in FIG. 2 and other embodiments, the fixing portion can be provided on both side surfaces of the trunk.
[0016]
In the embodiment shown in FIGS. 1 and 2, a fixing portion 42 (male or female surface fastener) is provided on the outer side surface of the trunk, while the fixing portion 62 is provided on the inner side surface of the bag of the protective member 60 described later. Bonding with (surface fastener corresponding to male or female mold), the trenker is fixed in the protective member. The trender does not extend to the sole of the foot and is not a structure in which the left and right trenders are connected by connecting members, but the foot and ankle are sufficiently protected because they are firmly fixed to the support body.
[0017]
The material of the trenders 40 and 41 is made of a plastic material that is the same material as the fixed portion. However, it is possible to form a material other than a plastic material as long as the material has a hardness that can be fixed similarly to the fixing portion.
The configuration shown in FIG. 5 is a configuration in which the hook-and-loop fastener 46 is joined to the fixing portion 42 of the trunker 40 or 41 and joined to the other trunker through the inside of the storage protection unit 60. It is also possible to do.
[0018]
The hinge portions 50 and 51 include a washer (not shown), a bearing (not shown) that engages with the trainer and the fixing portion, and a cap that engages with the bearing, and a long hole that is perforated in the fixing portions 30 and 31. The trainers 40 and 41 are configured to be slidably engaged with the fixed portions 30 and 31 through holes drilled in the trainers 40 and 41. In addition, the hinge part is swingable back and forth by a long hole drilled in the fixed part and a washer fitted between the bearing and the recessed part of the fixed part. However, it is possible to prevent the engagement from being disengaged and to hold it securely.
[0019]
The bag-shaped storage protection unit 60 is a bag body that is attached to the surface of the supporter main body 20, and is a double structure unit that has a function of storing and fixing the trunk card in the bag and protecting the sole from excessive impact. . A shock-absorbing material is arranged to cover and protect the sole from the side of the foot. As shown in FIG. 1, the supporter 20 is sewn directly to the supporter body 20, and there is no fear that it will be displaced or removed even if intense exercise is performed.
As shown in FIG. 2, it is the structure which adheres and joins to the surface fastener of the adhering part 42 of the trenders 40 and 41 with the surface fastener of the adhering part 62 inside this storage protection part formed in the bag shape.
The material of the bag-shaped storage protection unit 60 can be a loop surface or a hook surface material. With such a configuration, the entire bag-shaped storage protection part 60 becomes a fixing part, so that it is not necessary to provide a fixing part.
[0020]
Further, a configuration in which one of the trenders is fixed is also possible, and in the embodiment shown in FIG. 3, a configuration is adopted in which surface fasteners are attached to both ends at the tip of the outer trender and are joined to the protection portion and the main body fastener. .
In this configuration, the trender has a structure that does not exist on the sole, but the storage protection unit 60 serves as a protection unit for the entire sole, and the left and right trenders 40 and 41 are substantially joined together. It is possible to hold the ankles together with the left and right trunks and the storage protection unit. A configuration in which a hook-and-loop fastener is provided on the sole as in the configuration of still another embodiment of FIG. 5 is also possible. However, since the hook-and-loop fastener is not a configuration in which the left and right trenders are joined to each other, The section need not be made of hook-and-loop fastener material. By adopting the configuration as in the embodiment of FIG. 1 or FIG. 3, a durable holding effect is high, and an effect that makes it possible to hold the ankle reliably can be obtained. Thereby, it is possible to make it difficult to cause sprains due to external rotation and internal rotation.
[0021]
In another embodiment shown in FIG. 3, since the fixing portions 42 (surface fasteners) are provided on both side surfaces of the trender, it is possible to join the trender to the inner side surface of the bag of the protection unit 60 at an appropriate location. is there.
The trender does not extend to the sole of the foot and is not a structure in which the left and right trenders are connected by connecting members, but the foot and ankle are sufficiently protected because they are firmly fixed to the support body.
[0022]
As shown in FIG. 1, the band part 70 is a rectangular elastic cloth-like member that simultaneously covers and holds the fixing parts 30 and 31 and the supporter body 20 on the ankle. In this embodiment, it is fixed by a hook-and-loop fastener at the back side (back side) of the ankle. It has a role of holding the fixing portions 30 and 31 and the supporter main body 20, and can be reliably held even after intense exercise. In a normal supporter, there is no hinge mechanism and everything is integrated, so there is a drawback that holding is incomplete when an excessive force from a trainer or the like is applied to the band portion. However, in the present invention, the support device 10 receives an excessive force by providing the hinge protection parts 50 and 51 movable in response to the movement of the human body and the storage protection part 60 sewn on the supporter body 20 so that the human body can receive the excessive force. Since it is possible to avoid hitting the joint directly, it can be held at one place of the band portion 70.
[0023]
The support device of the present invention is a structure that compensates for the conventional drawbacks and further invents from the kinematic anatomical basis, and thus reduces the burden on the ankle. In addition, since the storage protection unit 60 maintains optimum holding on the supporter body 20 and the hinges 50 and 51 can swing, it is possible to avoid injuries such as sprains due to external rotation and internal rotation. In addition, it is possible to walk with peace of mind by using it not only for sports but also for elderly people, people with weak legs, and rehabilitation medicine.
In the embodiment shown in the drawings, the embodiment for the right foot is described in detail, but the embodiment for the left foot can be implemented in substantially the same manner.
[0024]
Furthermore, the support device of the present invention can be used by being installed inside ski shoes, mountain climbing shoes, etc., which are very burdensome on the ankle. In the current intense sport that puts a heavy burden on the feet of skis etc., the material installed inside the shoes is using a simple bandage or cylindrical supporter, and the holding effect was not expected at all . However, by using the support device of the present invention, it is possible to reduce the risk of injury even when playing intense sports with the ankle securely held.
[0025]
In still another embodiment shown in FIG. 5, a fixing portion 42 (surface fastener) is provided on the outer surface of the trender, while a fixing portion 62 (surface fastener) provided on the inner surface of the bag body of the protective member 60 described later. To fix the trenker in the protective member. The trender does not extend to the sole of the foot and is not a structure in which the left and right trenders are connected by connecting members, but the foot and ankle are sufficiently protected because they are firmly fixed to the support body.
[0026]
