Description

  The present invention relates to a garment for acquiring biometric data.

  An elastic garment that can be used when collecting data such as an electrocardiogram or electromyogram, or performing electrical therapy or electromagnetic wave therapy has been proposed (see Patent Document 1). In this elastic garment, the conductive fiber is knitted into an elastic fabric by float knitting, so that the exposed amount of the conductive fiber on the back side (the side in contact with the wearer's skin surface) is larger than the exposed amount on the front side. It is a configuration. That is, the electrode which contacts a wearer is formed by the conductive fiber exposed on the back side of the elastic fabric.

  In addition, it has been proposed that positive and negative electrodes that can come into contact with the skin surface of the wearer are attached to the clothing in an arrangement separated from each other (see Patent Document 2). These electrodes have a structure that can be mechanically engaged and disengaged with a connector part (a terminal for detection) of a terminal device used for collecting data such as an electrocardiogram. The detection device can be attached and detached.

Japanese Patent No. 4609923 JP2015-77270A

  If an electrode is to be formed on a cloth such as an elastic cloth as in the elastic garment disclosed in Patent Document 1, conductive fibers that are harder than synthetic fibers or natural fibers must be used. For this reason, there has been a difficulty that it is difficult to bring this electrode into surface contact with a three-dimensional and complicated curved surface, unevenness, flexible part, etc. existing on the skin surface of the wearer. That is, part or all of the electrodes may be out of contact with the skin surface (raised). Naturally, when the wearer performs an action such as exercise, not only surface contact but also reliable and continuous contact is difficult to obtain.

  In addition, in the elastic clothing of Patent Document 1, the strength of “elasticity”, which is an essential requirement, is “elastic stockings (unlike general-purpose stockings, which intentionally compresses the skin surface” as a representative embodiment. It is a considerably strong urging force so that it can be easily inferred from the fact that “the medical one having a strong urging force” is listed. In other words, the requirement for such a limited requirement can be said to be proof that the lifting of the electrode exists as a potential problem when it is assumed to be applied to general-purpose clothing.

  On the other hand, in the proposed technique shown in Patent Document 2, since the wearing state of the detection device with respect to the clothing is all left to the positive and negative electrodes provided directly on the clothing, the fixing force of the detection device with respect to the wearer of the clothing is almost constant. It goes without saying that you cannot get it. For this reason, if the wearer moves, the detection device easily shifts in position with respect to the wearer, resulting in a fundamental problem that correct measurement cannot be performed when collecting data such as an electrocardiogram.

The technology disclosed in Patent Literature 1 and the technology disclosed in Patent Literature 2 are fundamentally different in technical idea, and cannot be solved by any of the disclosed technologies (for example, fixing of a detection device). There are a lot of things to improve.
The present invention has been made in view of the above circumstances, and even when implemented as a general-purpose garment, the conductive surface can be brought into surface contact with the skin surface, and the skin surface is static or moving. The surface contact state can be maintained without being affected by the target, and the detection device can be easily attached / detached and securely fixed to the wearer at the time of wearing (the detection device even if the wearer moves) It is an object of the present invention to provide a garment for obtaining biometric data that can be reliably measured by the above.

In order to achieve the above object, the present invention has taken the following measures.
That is, the garment for acquiring biometric data according to the present invention has a body fabric body that is elastic enough to stretch and recover following the movement of the wearer, and the skin surface of the wearer with respect to the body fabric body. A conductive portion provided in an arrangement facing the conductive surface, and a device mounting portion that holds the detection device for acquiring biometric data from the wearer in the body main body in a state of being electrically connected to the conductive portion, The body cloth main body is provided with a pressing biasing portion that presses the conductive portion and the detection device held by the device mounting portion in a mutual contact direction, and the pressing biasing portion is It is characterized by having an urging force that enables the conductive portion and the detection device to be pressed even at the maximum extension caused by the movement of the wearer within the schedule.

When the direction surrounding the torso, leg, arm, or neck of the wearer is set as the horizontal direction, the conductive surface of the conductive portion is a size obtained by expanding the contact area of the detection contact included in the detection device at least in the horizontal direction. It is preferable to have a thickness.
The conductive portion may be disposed inside the device mounting portion in the middle, and the pressing biasing portion may be disposed outside the device mounting portion.

  Alternatively, the conductive portion is disposed inside the device mounting portion in the middle, and the body cloth main body is disposed outside the device mounting portion. The conductive portion may also serve as the pressing biasing portion by providing a biasing force that enables the conductive portion to be pressed against the detection device even at the maximum extension caused by the movement of the.

The device mounting portion may include a spacer member that restricts movement of the detection device by abutting against a facing side surface of the detection device.
The body cloth main body may be provided with a loading / unloading port that allows the detection device to be attached to and detached from the device mounting portion from the opposite side to the side facing the skin surface of the wearer.

  The biometric data acquisition clothing according to the present invention can bring the conductive surface into surface contact with the skin surface even when implemented as a general-purpose clothing, and whether the skin surface is static or dynamic. The surface contact state can be maintained without being affected, and the detection device can be easily attached / detached and securely fixed to the wearer at the time of wearing (the detection device can perform reliable measurement even if the wearer moves). )

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show a first embodiment of a garment for acquiring biometric data 1 according to the present invention (hereinafter referred to as “the garment 1 of the present invention”). The garment 1 of the present invention has a basic configuration in which a conductive part 3 for ensuring electrical continuity with the skin surface of the wearer is provided on a part of the body cloth body 2. The body cloth main body 2 is formed of a non-conductive fiber material in principle (at least the insulating region centered on the arrangement portion of the conductive portion 3). On the other hand, the conductive portion 3 is formed by exposing the conductive yarn at least on a surface directed to the skin surface of the wearer (hereinafter referred to as “conductive surface”).

In the garment 1 of the present invention, the body cloth body 2 is provided with a device mounting portion 4 that allows the detection device 5 to be detachable. When the detection device 5 is mounted on the device mounting portion 4, The detection device 5 and the conductive part 3 can be electrically connected.
Further, the body cloth main body 2 is provided with a pressing biasing portion 6. The pressing urging unit 6 is arranged so as to overlap the detection device 5 held by the device mounting unit 4 and presses the conductive unit 3 and the detection device 5 in the mutual contact direction.

  The detection device 5 is an electronic device for acquiring biological data such as heartbeat, body surface temperature, and pulse wave from the wearer. The detection device 5 applied in the first embodiment is a square type. However, the outer shape and size of the detection device 5, the arrangement and shape of a plurality of detection contacts 10 and 11 (generally two for positive electrodes and one for negative electrodes as shown in FIG. 3), etc. There is no particular limitation.

In many cases, the detection device 5 brings the detection contacts 10 and 11 into direct contact with the skin surface of the wearer or indirectly through a conductive pad with a jelly-like (gel-like) adhesive. The biometric data acquired in (1) is transmitted to an information processing device such as a computer installed in the vicinity by wireless or wired communication to create an electrocardiogram or electromyogram.
In the first embodiment, a case is shown in which the body cloth body 2 is a T-shirt type upper garment (including training wear and underwear). That is, the body fabric body 2 forms left and right sleeves with respect to a seamless tubular fabric in the circumferential direction, and opens a collar on one side in the tube axis direction ([Ariaki]: a hole through which the head of the wearer passes. ). And with respect to such an upper-cloth-type body cloth body 2, the conductive portion 3 and the device mounting portion 4 are arranged so as to correspond to the chest of the wearer.

  Moreover, in this 1st Embodiment, the spacer member 12 is provided with respect to the inner surface side (side which faces a wearer's skin surface) of the body fabric main body 2, and the apparatus mounting part 4 is formed in this spacer member 12. As shown in FIG. The conductive member 3 is arranged on the inner side (the wearer's skin side) so as to sandwich the spacer member 12 (the device mounting portion 4) in the middle, and pressed against the outer side (the clothing outer side) of the device mounting portion 4. It is assumed that the force unit 6 is arranged.

Note that a wiring portion for the conductive portion 3 may be formed on the body cloth body 2 or the spacer member 12.
Hereinafter, the body body 2 will be described in detail first. The body fabric body 2 can be knitted using a non-conductive fiber material as described above. Specific examples of the fiber material include synthetic fiber (for example, polyester fiber and nylon fiber), natural fiber, and a material obtained by mixing synthetic fiber and elastic yarn.

Moreover, the knitting structure employ | adopted for the body fabric main body 2 is not limited at all. For example, a flat knitting, a rubber knitting, a smooth knitting, a pearl knitting, or a changed structure thereof (for example, a Milan rib or a cardboard knit) can be employed. Naturally, for knitting, not only a circular knitting machine but also a flat knitting machine can be used. In addition, the organization knitted by the weft knitting as listed above may be a knitting organization (tricot knitting, Raschel knitting, Miranese knitting, etc.) knitting by warp knitting.

When knitting the body 2, the elastic yarn is further mixed so that abundant expansion and contraction can be obtained in the direction of expanding and contracting the cylinder diameter (peripheral length) and the cylinder shaft length. This is suitable for fixing the mounting position and facilitating removal.
Here, the “elastic yarn” maintains a contracted state when no tensile force is applied (non-extension = normal state), and freely expands according to the tensile force when a tensile force is applied, and When the tensile force is released and the load is restored when no load is applied, the material is restored (contracted) from the stretched state to the original contracted state.

  As a method for mixing elastic yarns, a form selected from at least one of inlay, drawing, plating, knit, or composite yarn may be adopted. For elastic yarn, polyurethane or rubber-based elastomer material may be used alone, or covering yarn using polyurethane or rubber-based elastomer material for “core” and nylon or polyester for “cover” can do. By employing such covering yarn, functions such as hydrophilicity, water repellency, corrosion resistance / corrosion resistance, and coloring can be imparted to the garment 1 of the present invention. It is also useful for improving the feel (feel) and controlling elongation.

  The body fabric body 2 knitted and knitted in this manner sufficiently follows the movement of the wearer, and has elasticity to such an extent that it can be stretched and recovered. The stretchability of the body fabric body 2 is such that when the longitudinal stretch along the height direction of the wearer and the lateral stretch along the waistline direction of the wearer are caused, the vertical stretch may hinder the movement of the wearer. It has a weak elastic resistance to the extent that the body body 2 is perfectly fitted to the wearer in the horizontal expansion and contraction, and the strong elastic resistance to prevent the slippage has developed a strong tightening force and increased the pressure on the skin surface. Those are preferred.

That is, when the wearer wears, the Y direction (height direction) has a small elastic resistance and easily expands and contracts following the movement of the body, while the elastic resistance is large and hardly stretched in the X direction (trunk direction). It is preferable that the cloth main body 2 is pressed in the Z direction (body) as a result.
In this way, a specific knitting method for knitting a cylindrical fabric that has a strong tightening force because it is relatively easy to stretch in the Y direction and difficult to stretch in the X direction, and presses the body fabric body 2 in the Z direction. For example, a method of performing milling with a covering yarn using polyurethane equivalent to 22 dtex and inlaying about 110 dtex of polyurethane as an insertion yarn can be cited as a method employing a knitting structure of a milling knitting inlay.

  Next, the conductive part 3 will be described in detail. The conductive portions 3 are provided in a state where the same number (conductive portions 3a, 3b) as the detection contacts 10, 11 are separated and insulated from each other in order to make contact with the detection contacts 10, 11 of the detection device 5 separately. The size of each conductive portion 3a, 3b (especially the surface used as the conductive surface) should be larger than the detection contacts 10, 11 of the detection device 5 (contact area when contacting the skin surface of the wearer). Is preferred. Specifically, when the direction surrounding the torso, neck, legs, arms, or fingers of the wearer is set as the horizontal direction (see arrow W in FIG. 3), at least the horizontal direction (W) Is the enlarged size.

Thus, by enlarging the conductive portions 3a and 3b, there is an advantage that reliable conduction with the skin surface of the wearer can be obtained, and that the conduction can be reliably maintained even when the wearer moves. The extent of enlargement can be appropriately changed depending on the type of biometric data to be obtained, the arrangement of the conductive surface (contact location with the wearer), and the like.
The planar shape of each of the conductive portions 3a and 3b was such that it was laid down so that the convex protrusions face each other as shown in FIG. However, it is also possible to use a bowl shape (L-shape) as shown in FIG. 4, and the planar shape of the conductive portions 3a and 3b is the size and shape of the detection device 5, the shape and structure of the detection contacts 10 and 11. These can be changed as appropriate according to the arrangement.

The conductive yarn forming the conductive portions 3a and 3b is formed of a metal strand, a metal-coated wire, carbon fiber, or the like.
Convex shapes and saddle-shaped (L-shaped) may be formed integrally with the same conductive material, or a plurality of conductive materials with different materials may be sewn, bonded, locking tools (snap buttons, etc.) ), Engaging structures (such as hook-and-loop fasteners), etc., may be combined to form a composite structure.

As specific examples of the metal component in the metal strand or the metal-coated wire, gold, platinum, silver, copper, nickel, chromium, iron, copper, zinc, aluminum, tungsten, stainless steel and the like are suitable. In addition, pure metals such as titanium, magnesium, tin, vanadium, cobalt, molybdenum, tantalum, and alloys thereof (brass, nichrome, etc.) can be used.
As the metal strand, not only a continuous long wire but also a twisted single wire can be used. On the other hand, when the core material is a resin fiber, wire or animal or plant fiber in a metal-coated wire, a wet coating method or a powder adhesion method can be used, including plating treatment employed in resin plating methods, etc. Good. Further, when the core material is a metal wire, a thermal spraying method, a sputtering method, a CVD method, or the like can be employed. Monofilaments, multifilaments, and spun (spun) yarns may be used as the core material, or wooly processed yarns, covering yarns such as SCY and DCY, and bulky processed yarns such as fluffed yarns may be used.

In addition, these metal wires, metal-coated wires, and carbon fibers may be mixed with non-conductive fibers. For example, a spun (spun) yarn can be used for blended yarn, covering yarn, or assortment. It is also possible to mix with a fiber having a melting point and a softening point higher than the heat setting temperature.
As the knitting structure used for the conductive surface, for example, a flat knitting, a rubber knitting, a smooth knitting, a pearl knitting, or a changed structure thereof (for example, Milan rib, corrugated cardboard knit, Kanoko, pile, etc.) can be adopted.

  Depending on the case, it is also possible to adopt a structure in which the base yarn portion serving as the foundation of the conductive portions 3a and 3b is knitted as a full knit of the above-mentioned various knitting structures and knitted by float knitting on the conductive surface side of the same region. . In this case, the float yarn of the float knitting rises beyond the height in the thickness direction due to the knitting structure of the ground yarn. Therefore, the contact of the conductive surface is further ensured with respect to a three-dimensional and complicated curved surface, unevenness, flexible part, etc. existing on the skin surface of the wearer. In addition, it will follow even more precise movements of the skin surface. Therefore, reliable conductivity can be obtained.

  When the entire conductive portions 3a and 3b (the entire fabric thickness) are knitted using the above-described various knitting structures using the above-described conductive yarn, not only the conductive surface but also the surface opposite to the conductive surface. This also has a conductive structure, and conduction between the front and back surfaces is also obtained. In such a case, the surface opposite to the conductive surface can be used as an electrode surface for electrically connecting to the detection contacts 10 and 11 of the detection device 5.

As shown in FIG. 2, in the first embodiment, the detection contact 10 of the detection device 5 is exactly the one surface of the conductive portions 3a and 3b as the conductive surface and the other surface opposite to the conductive surface as the electrode surface. , 11 is used.
Next, the device mounting part 4 will be described in detail. The device mounting portion 4 is a place for holding the detection device 5 with respect to the body cloth main body 2. In a state where the detection device 5 is held by the device mounting portion 4, the detection device 5 is in a state in which the relative positional relationship with the body cloth body 2 is not displaced even when the wearer operates. Is preferred. Therefore, in the first embodiment, as described above, the spacer member 12 is provided on the inner surface side of the body cloth body 2, and the device mounting portion 4 is provided on the spacer member 12.

  Specifically, the spacer member 12 is formed in a board shape having a thickness equal to or less than the thickness of the detection device 5, and the detection device 5 is fitted by opening or recessing the board surface. It has a structure. That is, the outer peripheral side surface of the detection device 5 comes into contact with the opening (or the recess) provided in the spacer member 12, the detection device 5 is held, and the movement of the detection device 5 with respect to the body cloth body 2 is substantially omitted. In this case, the device mounting portion 4 is formed at a portion that contacts the detection device 5.

The material for forming the spacer member 12 includes a variety of materials such as cloth such as towels, cotton, three-dimensional knitted fabric, shredder waste, foamed polystyrene, sponge, rubber, silicone, urethane, air pack (air bag), and gel encapsulated bag. It can be adopted.
Note that the device mounting portion 4 provided on the spacer member 12 may be any device as long as it is in contact with at least two locations facing each other (for example, a pair of diagonal positions of the detection device 5) on the side surface of the detection device 5. It is not necessary to contact the entire circumference of the device 5. In some cases, small spacer members 12 that are separated from each other are arranged so as to abut only on two opposing side surfaces or diagonal portions of the detection device 5, and the device mounting portion 4 is disposed between the two spacer members 12. May be formed.

In the first embodiment, the spacer member 12 is provided so as to correspond only to about half a circumference of the body cloth body 2, but it may be a range less than a half circumference or provided on the entire inner surface of the body cloth body 2. Also good.
Examples of the joining method when attaching the spacer member 12 to the body cloth body 2 or attaching the conductive portion 3 to the spacer member 12 include adhesion with an adhesive, thermal fusion with a thermoplastic resin, Appropriate methods such as sewing with a sewing machine or hooking with a hook-and-loop fastener can be adopted.

Next, the pressing urging unit 6 will be described in detail. The pressing and urging unit 6 has an urging force that enables the conductive portions 3a and 3b and the detection device 5 to be pressed even at the time of the maximum extension caused by the movement of the wearer within the schedule.
The pressing and urging unit 6 is, for example, by performing knitting by performing elastic thread insertion, thread switching, knitting structure change, loop length change, or a combination of these operations during knitting of the body 2. It can be formed integrally with the cloth body 2.

  Specifically, the fiber material and the knitting structure forming the pressing and urging portion 6 are basically the same as those employed for the body fabric body 2 except for the strength of the urging force. As with the body body 2, the pressing and urging portion 6 also causes vertical expansion and contraction along the height direction of the wearer and horizontal expansion and contraction along the waist direction of the wearer. The same applies to the point that the horizontal expansion and contraction is strengthened so that the wearer's waistline can be firmly fitted.

In the first embodiment, the pressing biasing portion 6 is illustrated as being formed in a cylindrical shape as in the case of the body cloth body 2, but the pressing biasing portion 6 corresponds to the detection device 5. You may provide so that only a part may exist.
In some cases, the pressing and biasing portion 6 can also be formed by joining a fabric having a strong biasing force knitted separately from the body fabric body 2 to the body fabric body 2 by sewing or the like.

  As is clear from the above description, in the garment 1 of the present invention, when the detection device 5 is mounted on the device mounting portion 4 and then the wearer wears the garment 1 of the present invention, the pressing biasing portion 6 is The detection device 5 is pressed against the conductive portions 3a and 3b by a strong biasing force, and the conductive portions 3a and 3b are pressed against the skin surface of the wearer. As a result, the detection contacts 10 and 11 of the detection device 5 and the conductive portions 3a and 3b are surely brought into surface contact with each other and become conductive, and the conductive portions 3a and 3b and the skin surface of the wearer are reliably in surface contact. It becomes a conductive state. These conduction states are maintained even when the wearer moves, and thus the detection device 5 can reliably acquire biological data.

As described above, the garment 1 of the present invention can be implemented as a general-purpose garment (other than a medical garment having a strong biasing force enough to intentionally press the skin surface). Of course, it is needless to say that medical implementation is possible.
By the way, as shown in FIG. 5, the body cloth body 2 is provided with a loading / unloading port 16 in an arrangement that matches the device mounting portion 4 from the opposite side (outside the clothing) to the side facing the skin surface of the wearer. be able to. The access port 16 is for making the detection device 5 detachable from the device mounting portion 4. In the illustrated example, an opening / closing tool 20 such as a line fastener (generally referred to as “zipper” or “chuck”) that can be opened and closed in the height direction of the wearer is attached to the loading / unloading port 16.

  In this manner, if the entrance / exit 16 is provided in the body cloth body 2, the detection device 5 can be attached to and detached from the device mounting portion 4 while wearing the garment 1 of the present invention, which is extremely convenient. Further, by providing the opening / closing tool 20 at the entrance / exit 16, it is possible to obtain a holding and stabilizing action, a drop-off preventing action, a visual blocking action (improving appearance), and the like of the detection device 5 attached to the device attachment portion 4. It becomes.

Note that when opening / closing the opening / closing tool 20, the opening / closing tool is prevented in order to prevent the detection apparatus 5 from being caught due to being caught by the detection apparatus 5, or from being damaged. It is preferable to attach the backing fabric 21 in an arrangement that partitions the space 20 and the device mounting portion 4.
Further, when a non-conductive lining 22 is attached to the inside of the conductive portions 3a and 3b that matches the device mounting portion 4, both the conductive portions 3a and 3b are connected, and the detection contact of the detection device 5 is detected. There is an advantage that it is possible to prevent the occurrence of creases or misalignment at the contact portions with 10 and 11.

6 to 9 show a second embodiment of the garment 1 of the present invention. The second embodiment is a case where the detection device 5 is applied to an elliptical type instead of the square type described in the first embodiment, and the detailed configuration is different due to this.
In the detection device 5 applied in the second embodiment, the detection contacts 10 and 11 are distributed and arranged near both ends in the longitudinal direction of the elliptical shape. Therefore, as shown in FIGS. 8 and 9, the conductive portions 3 a and 3 b are also arranged so as to be distributed near both ends of the detection device 5 in the longitudinal direction.

Each of the conductive portions 3a and 3b has a dome shape that covers the detection device 5 across its short side. In addition, a bag-like dead end structure is provided at a position covering the longitudinal end portion of the detection device 5, and the detection device 5 is contained so as to prevent its longitudinal movement and escape.
Moreover, in this 2nd Embodiment, as shown in FIG. 7, the electroconductive parts 3a and 3b are arrange | positioned inside on both sides of the apparatus mounting part 4, and the body cloth main body 2 is outside the apparatus mounting part 4. As shown in FIG. As arranged. Each conductive part 3a, 3b has an urging force that enables pressing against the detection device 5 even at the maximum extension caused by the movement of the wearer within the schedule, and by having this urging force, Each of the conductive portions 3a and 3b also serves as the pressing and urging portion 6.

Here, “scheduled movement of the wearer” means a movement that is necessary for the acquisition of biometric data but excludes other extreme movements and special movements that are not performed in daily life. Shall.
Accordingly, in the second embodiment, the pressing and biasing unit 6 (conductive portions 3a and 3b) presses itself (the conductive portions 3a and 3b) against the detection device 5 with a strong biasing force. In addition, the conductive portions 3a and 3b are pressed against the skin surface of the wearer due to the elasticity of the body cloth body 2 with the tightening force. As a result, the detection contacts 10 and 11 of the detection device 5 and the conductive portions 3a and 3b are surely brought into surface contact with each other and become conductive, and the conductive portions 3a and 3b and the skin surface of the wearer are reliably in surface contact. It becomes conductive.

Even if such a configuration is adopted, the cylindrical pressing and biasing portion 6 integrated with the body cloth body 2 as described in the first embodiment can be used in the second embodiment as well. It is.
As a specific method for imparting an urging force to each of the conductive portions 3a and 3b, the conductive yarns are aligned in the region where the conductive portions 3a and 3b are formed on the basis of a stretchable fabric, and plating and inlay are performed. A method may be employed in which the yarns are mixed with the same yarn or the like, or conductive yarns (including covering yarns and twisted yarns having conductivity) are knitted by yarn feeding switching.

  In the second embodiment, since the conductive portions 3a and 3b are arranged apart from each other in accordance with the elliptical shape of the detection device 5, an opening is formed between the conductive portions 3a and 3b. It is configured to be used as the entrance / exit 25 of the detection device 5. The entrance / exit 25 is accompanied by a contracting force in the direction of reducing the opening due to the conductive portions 3a, 3b and the base fabric having elasticity and tightening force. Therefore, at the time of the insertion / extraction operation of the detection device 5 as shown in FIGS. 8 (b) to 8 (d), the opening edge of the insertion / exit opening 25 surrounds (tightens) the detection device 5 and exhibits a locking force. There is an advantage that there is no failure in taking in and out the detection device 5 as a non-slip effect (a drop-off preventing effect). Further, as shown in FIG. 8D, when the insertion is completed, the outlet / entry port 25 automatically reduces in diameter, which leads to an action of increasing the holding force of the detection device 5.

In this type of elliptical type detection device 5, a sensor unit 27 for detecting body surface temperature, pulse wave, etc. is provided at an intermediate position in the longitudinal direction (between the detection terminals 10 and 11). There may be. The entrance / exit 25 can be used effectively for exposing the sensor unit 27 and bringing it into contact with the skin surface of the wearer.
Other configurations and operational effects are substantially the same as those of the first embodiment, and detailed description thereof is omitted here.

In addition, in the conductive parts 3a and 3b, the position covering the longitudinal direction end of the detection device 5 is not limited to the bag-shaped dead end structure. For example, as shown in FIG. 10, it is possible to prevent the detection device 5 from moving or escaping in the longitudinal direction by providing a narrowing guide portion 30 by sewing or bonding to form an opening 31 narrower than the detection device 5. Can get.
In addition, the elliptical type detection device 5 is not limited to adopting a configuration that also serves as the pressing and urging portion 6 against the conductive portions 3a and 3b. For example, as shown in FIGS. 11 and 12, it is possible to employ conductive portions 3a and 3b that are substantially the same as those described in the first embodiment.

FIG. 13 shows a third embodiment of the garment 1 of the present invention. In the third embodiment, the pressing urging unit 6 is arranged in a hooked manner with respect to the body cloth body 2 so that the operating range of the urging force can be distributed to the whole body body body 2 in a well-balanced manner. . Other configurations and operational effects are substantially the same as those of the first embodiment, and detailed description thereof is omitted here.

In this 4th Embodiment, the site | part in which the electroconductive parts 3a and 3b are arrange | positioned with respect to the body cloth main body 2 and the site | part in which the apparatus mounting part 4 of the detection apparatus 5 is arrange | positioned are separated, and a conductive line is between these. 35 is wired. As described above, in the conductive portions 3a and 3b, the use of the surface opposite to the conductive surface as the electrode surface is not limited.

Other configurations and operational effects are substantially the same as those of the first embodiment, and detailed description thereof is omitted here.
FIG. 15 shows a fifth embodiment of the garment 1 of the present invention. The fifth embodiment shows an example in which a ventilating portion 37 is provided in the body fabric body 2 so as to penetrate between a surface facing the skin surface of the wearer and an outer surface by a porous structure or a mesh structure. Providing such a ventilation part 37 facilitates sweating of the wearer when collecting data from the conductive part 3 while performing an exercise or the like while wearing the garment 1 of the present invention. It is possible to prevent overload from acting on. Therefore, it is useful to obtain accurate data that is not affected by disturbance such as the constitution and physical strength of the wearer or the data collection environment.

Such a ventilation part 37 is realizable by adopting a transfer or a lace knitting, etc. when knitting the body fabric body 2. In some cases, such as separate fabrics knitted by transfer or lace stitching, porous fabrics (including non-woven fabrics) and mesh materials are attached to the body fabric body 2 by bonding or sewing. Also good.
Needless to say, the arrangement and number of the ventilation portions 37 can be changed as appropriate according to the arrangement of the clothing shape and the conductive portion 3.

FIG. 16 shows a sixth embodiment of the garment 1 of the present invention. The sixth embodiment shows another example of the body cloth body 2. In the example shown, it is a half-pants type undergarment. In such a case, the conductive portion 3 and the pressing biasing portion 6 can be arranged in correspondence with the thigh, waist, buttocks, etc. of the wearer.
FIG. 17 is an embodiment obtained by further developing the fourth embodiment (FIG. 14). Basically, the present embodiment is the same as the fourth embodiment in that the conductive portions 3a and 3b and the device mounting portion 4 of the detection device 5 are separated from each other and the conductive lines 35 are wired between them. The embodiment is characterized in that the conductive line 35 is detachable between the conductive portion 3 a and the device mounting portion 4 and between the conductive portion 3 b and the device mounting portion 4.

  By adopting such a configuration, the conductive portions 3a and 3b can be freely exchanged for a plurality of types having different shapes and areas, and the conductive portions 3a and 3b and devices for the body cloth body 2 (not shown). An advantage that the arrangement of the mounting portion 4 can be freely set is obtained. In particular, it is useful when the conductive portions 3a and 3b are desired to increase the contact area with the skin surface of the wearer.

  As the conductive line 35, it is preferable to use a conductive line having elasticity in the longitudinal direction and flexibility for bending. By doing in this way, between the electroconductive part 3a and the apparatus mounting part 4, and between the electroconductive part 3b and the apparatus mounting part 4 becomes freely movable within a predetermined range, The electroconductive part 3a, 3b In addition, the device mounting unit 4 can follow up independently of the movement of the wearer, and there is an advantage that stable data acquisition is possible.

  Button-shaped metal hooks are used for the joint portions 42a and 42b used for connecting the device mounting portion 4 and the conductive line 35 and the joint portions 43a and 43b used for connecting the conductive line 35 and the respective conductive portions 3a and 3b. It is recommended to use a combination. In addition, about the hook engaging tool, if the male and female types are reversed at both ends of the conductive line 35, the device mounting portion 4 and the conductive portions 3a and 3b are directly coupled without using the conductive line 35. Options can also be provided, which is convenient.

  Needless to say, the pressing biasing portion 6 is made conductive, and the pressing biasing portion 6 and the joint portions 42a and 42b are electrically connected. Therefore, by making the pressing biasing portion 6 contact the skin surface of the wearer, the pressing biasing portion 6 can also act as a conductive portion (the conductive portion 3a connected via the conductive line 35). , 3b will cause an enlargement of the conductive surface).

  In addition, while preparing the combination body of these apparatus mounting parts 4 and electroconductive part 3a, 3b as a separate body from the body fabric main body 2, the area | region where the tension | tensile_strength is strong in all or one part in the body fabric body 2 The combination of the device mounting portion 4 and the conductive portions 3a and 3b is provided at a required location (location where biometric data is to be obtained) each time in the strong tension region. It is good also as a structure which enables attachment with sewing, adhesion | attachment, a hook-and-loop fastener, etc.

By the way, in the present invention, the contact between the conductive portions 3a and 3b and the detection contacts 10 and 11 of the detection device 5 is forcibly pressed by the urging force of the pressing urging portion 6, so that even surface contact is sufficient. Reliable conductivity can be obtained.
However, although illustration is omitted, the structure in which the conductive portions 3a and 3b and the detection contacts 10 and 11 of the detection device 5 are mechanically engaged with each other by the female hook and the male hook is further ensured. Conductivity can be obtained.

Even when surface contact is adopted, anti-slip treatment is applied to the conductive surfaces (skin surface side of the wearer) and electrode surfaces (detection contact points 10 and 11 side of the detection device 5) of the conductive portions 3a and 3b. By setting, it is possible to prevent positional displacement due to the sliding of the conductive portions 3a and 3b, and as a result, it is possible to increase the conductivity.
This anti-slip treatment is performed by mixing at least one of a heat-seal material or a heat-seal material with the conductive yarn used for forming the conductive parts 3a and 3b, and then knitting the conductive part 3 and then heat setting after knitting. This is a process in which a portion where the conductive yarn intersects in the knitted structure is fused or bonded with a resin. Therefore, heat fusion materials and heat fusion materials are excellent in elasticity (elasticity), heat fusion by heating, and high degree of elasticity without loss of elasticity (elasticity) at the heat fusion site. It is good to use what possesses property (elasticity).

The difference between thermal fusion and thermal fusion is in the strength of the bonding force generated by cooling from the semi-molten state (the strong bonding force is thermal fusion, and the weaker is the thermal fusion. is there).
Specifically, a low melting point polyurethane can be given as a representative example of the heat-sealing material or the heat-sealing material. Low melting point polyurethane is an optimal example. In addition, condensation polymers such as polyethylene, nylon (6 and 66), polypropylene, polyvinyl chloride, vinyl polymers, polyamides, and the like can be used.

  In the method of mixing the heat-bonding material or the heat-bonding material with the conductive yarn, the conductive yarn is used as a “core (or cover)”, and the yarn made of the heat-bonding material or the heat-bonding material is used as “ A method using a covering yarn (which may be SCY or DCY) used as a “cover (or core)”, or a conductive yarn or a yarn made of a heat-fusion material or a yarn made of a heat-bonding material are arranged together (as a plating knitting) There is a method).

The conductive yarn after heat setting is required to have a conductive component exposed on a part or all of the yarn surface. Therefore, the exposed portion of the conductive yarn is generated by appropriately adjusting the thickness and amount (number) of yarns made of heat-fusion material or yarns made of heat-fusion material, and the heating temperature when performing heat setting. Like that.
The present invention is not limited to the above-described embodiments, and can be further appropriately changed according to the embodiments.

  For example, the body cloth main body 2 may have a cylindrical shape, a tapered cylindrical shape, a gourd cylindrical shape, or the like. Further, in these cases, it is not always required to be seamless in the circumferential direction, and the body fabric body 2 can be formed in a band shape and wound around the target site of the wearer. In order to maintain the winding state, it is possible to employ various fastening methods such as strap fastening, button fastening, hook fastening, hook-and-loop fastening, etc. in addition to belt fastening around the circumferential direction. If necessary, an adjustment function for making the circumference (cylinder diameter) at the time of fastening variable may be provided.

The conductive portions 3a and 3b can also be formed by a method of sewing (embroidery) conductive yarn on a base fabric or printing using conductive ink, conductive silicon, or the like.
As shown in FIG. 5, in the body cloth body 2, the opening / closing tool 20 is provided in the loading / unloading port 16 when the loading / unloading port 16 is provided on the opposite side (clothing outer side) from the side facing the skin surface of the wearer. Is not limited. In the case where the opening / closing tool 20 is provided, as the opening / closing tool 20, it is possible to employ a belt stopper, a string stopper, a button stopper, a hook stopper, a hook-and-loop fastener stopper, etc. wound in the circumferential direction in addition to the wire fastener. .

  The outer shape and size of the detection device 5, the number and arrangement of the detection contacts 11, the shape, the connection structure with the counterpart contact, and the like are not limited at all. Therefore, it goes without saying that in the garment 1 of the present invention, the number and arrangement of the conductive portions 3, the shape, the connection structure with the mating contact, and the like can be appropriately changed in accordance with the detection device 5 to be mounted. The same applies to the device mounting portion 4 and the pressing biasing portion 6 as the conductive portion 3.
