Embodiment for Carrying Out the Invention

[0009] (Embodiment) In the present embodiment, a supporter capable of changing the state of the contact surface between a robot and a person as needed will be described. Note that each of the embodiments described below shows a specific example of the present invention. Therefore, numerical values, shapes, materials, components, arrangements and connection forms of the components shown in the following embodiments are examples and are not intended to limit the present invention. Therefore, among the components in the following embodiments, the components not described in the independent claims are described as optional components.

[0010] Also, each figure is a schematic diagram and is not necessarily drawn precisely. Therefore, for example, the scales in each figure do not necessarily match. Also, in each figure, substantially the same configuration is denoted by the same reference numeral, and overlapping descriptions are omitted or simplified.

[0011] Also, in this specification, terms indicating the relationship between elements such as parallel or perpendicular, terms indicating the shape of elements such as rectangular or straight line, and numerical ranges are not expressions representing only a strict meaning, but are expressions meaning substantially equivalent ranges, for example, including a difference of about several percent.

[0012] Also, in this specification, the terms "above" and "below" do not refer to the upward direction (vertically upward) and the downward direction (vertically downward) in an absolute spatial recognition, but are used as terms defined by a relative positional relationship based on the stacking order in a stacked configuration.

[0013] [Configuration] First, the components of the supporter in the embodiment will be described. FIG. 1 is a schematic diagram showing the structure of the supporter 1 in the embodiment. The supporter 1 is a supporter 1 that is worn on an object or a person and used, and includes a friction temperature and humidity variable mechanism 2 that adjusts friction, temperature, and humidity on the surface of the supporter 1. The friction temperature and humidity variable mechanism 2 includes a bag-shaped fabric 3, a particle pack 40, a conductive wire body 10, an air ejection tube 30, and a spray mechanism 20.

[0014] The fabric 3 is made of cotton such as gauze, silk, or synthetic fiber. The fabric 3 is bag-shaped. The fabric 3 encloses the particle pack 40, the conductive wire body 10, the air ejection tube 30, and the spray mechanism 20. For example, the fabric 3 realizes a bag-shaped form of 110 mm × 80 mm × 10 mm.

[0015] The particle pack 40 is provided inside the bag-shaped fabric 3. The particle pack 40 contains a plurality of particles. The particle pack is filled with particles. The particles may be, for example, grains of cereals such as brown rice or beads. The particle pack may have a size that covers about half of the surface area of the bag-shaped fabric 3. The particles filled in the particle pack 40 prevent the cross-section of the air ejection tube 30 from being crushed and the air blowing from being stopped when a load is applied to the bag-shaped fabric 3. Also, the particles serve to thinly spread the air over the entire portion of the bag-shaped fabric 3 where the particle pack 40 is provided.

[0016] The conductive wire body 10 is provided between a plurality of particles in the particle pack 40. The conductive wire body 10 is connected to a power source existing outside the supporter 1 and generates heat when energized. The conductive wire body 10 is a specific example of a heating device. For example, the heating device is a conductive wire body having an electric resistance that converts electric power from a power source into heat.

[0017] The air ejection tube 30 is a tube for ejecting air supplied from outside the supporter 1. The air ejection tube 30 is provided outside or inside the particle pack and inside the bag-shaped fabric 3. The air ejection tube 30 is made of resin, rubber, silicone, or the like. The air ejection tube 30 may be made of metal. The air ejection tube 30 introduces air from outside the bag-shaped fabric 3 into the inside of the bag-shaped fabric 3 and ejects it. The air ejection tube 30 is flexible and can be installed in a free shape within the fabric 3. The air ejection tube 30 has a plurality of holes on the tube and ejects air from the plurality of holes.

[0018] The supporter 1 may include a plurality of air ejection tubes 30. At this time, a first air ejection tube provided outside the particle pack and inside the bag-shaped fabric, which introduces air from outside the bag-shaped fabric into the inside of the bag-shaped fabric and ejects it, an air drying device that makes the air from outside the bag-shaped fabric into dry air, and a second air ejection tube that introduces the dry air into the inside of the bag-shaped fabric 3 and ejects it, and a third air ejection tube provided outside the particle pack and inside the bag-shaped fabric, which introduces air injected from outside the bag-shaped fabric into the inside of the bag-shaped fabric and ejects it, may be provided.

[0019] Further, the first, second, and third air ejection tubes are tubes branched at a branch portion provided in the air supply tube from an air supply tube provided outside the bag-shaped fabric, and may include at least one or more valves capable of controlling the air flowing into the first, second, and third air ejection tubes.

[0020] Further, the second air ejection tube is a tube that merges with the first air ejection tube at a merging portion provided in the first air ejection tube, and the second air ejection tube has a structure provided such that the air drying device is located between the branch portion and the merging portion.

[0021] The spray mechanism 20 includes a liquid ejection tube 22. The liquid ejection tube 22 is made of resin, rubber, silicone, or the like. The liquid ejection tube 22 may be made of metal. Inside the spray mechanism 20, a region for holding liquid is provided. The liquid can be inserted from the outside with a syringe, a tube, or the like.

[0022] The liquid ejection tube 22 is provided outside the particle pack 40 and inside the bag-shaped fabric 3, and ejects the liquid held inside by the compressed air supplied from outside the bag-shaped fabric 3. Due to the adhesion of the liquid ejected onto the bag-shaped fabric 3, the friction between the bag-shaped fabric 3 and the object increases. Also, due to the liquid ejected onto the bag-shaped fabric 3, the humidity between the bag-shaped fabric 3 and the object increases.

[0023] The liquid ejection tube 22 is flexible and can be installed in a thin and flexible shape inside the fabric 3. The liquid ejection tube 22 has a plurality of holes on the tube and ejects the liquid from the plurality of holes. Here, the liquid is, for example, pure water, lotion, or emulsion.

[0024] It includes an air injection port 81 for injecting air from a third air ejection tube, a flow path following the air injection port 81, and an ejection port 83 provided at the end of the flow path where the injected air is ejected. In the flow path, a constriction 82 is provided that is narrower than other parts of the flow path. It has a branch flow path 85 that branches from a part of the section from the constriction 82 to the ejection port 83 in the flow path, and a liquid holding space connected to the branch flow path 85. Here, a liquid injection port 80 for injecting liquid from the outside may be provided in the liquid holding space. Here, the air injection port 81 is a specific example of the injection port.

[0025] [Structure] Next, the structure of the supporter 1 will be described. FIG. 2 is a cross-sectional view showing the outline of the supporter 1 in the embodiment. As described above, the supporter 1 includes the spray mechanism 20, the conductive strip 10, the particle pack 40, and the air ejection tube 30.

[0026] First, a particle pack 40 is installed inside the surface of the bag-shaped fabric 3 that is close to the surface where the supporter 1 contacts the object 100. Then, a conductive wire body 10 is installed in the particle pack 40. The conductive wire body 10 may be installed so as to crawl evenly among the particles filled in the particle pack 40.

[0027] Next, a spray mechanism 20 is installed along the surface of the particle pack 40 on the side opposite to the surface where the supporter 1 contacts the object 100. The spray mechanism 20 has a liquid ejection tube 22, and the liquid ejection tube 22 may be installed so as to extend from the surface of the particle pack 40 where the spray mechanism 20 is installed toward the surface where the particle pack 40 contacts the object 100.

[0028] Then, an air ejection tube 30 is installed on the surface of the spray mechanism 20 on the side where the spray mechanism 20 contacts the particle pack 40. Air is blown into the spray mechanism 20 through a tube 31 from the air ejection tube 30. Then, the liquid held in the spray mechanism 20 is ejected onto the surface where the bag-shaped fabric 3 contacts the object through the liquid ejection tube 22 by the compressed air sent from the tube 31.

[0029] Note that the installation methods of the spray mechanism 20, the conductive wire body 10, the particle pack 40, and the air ejection tube 30 are not limited to the above methods.

[0030] Next, another example of the structure of the supporter 1 will be described. FIG. 3 is a cross-sectional view showing details of the supporter 1 in the embodiment. The friction temperature and humidity variable mechanism 2 has a spray mechanism 20 for discharging a liquid. Cotton 24 is installed in the spray mechanism 20. A liquid such as pure water is supplied to the spray mechanism 20 from the outside of the supporter 1, and the cotton 24 is wetted with the liquid such as pure water.

[0031] The liquid ejection tube 22 sucks up a liquid such as pure water from an insertion portion 23 where the liquid ejection tube 22 is connected to the spray mechanism 20. The liquid ejection tube 22 extends to the ejection port 70, and at the ejection port 70, the liquid such as pure water is ejected onto the fabric 50. A wick 60 may be provided at the ejection port 70.

[0032] A particle pack 40 is installed between the spray mechanism 20 and the fabric 50. The particle pack is filled with, for example, brown rice 41. Then, an air ejection tube 30 and a conductive strip 10 are installed between the brown rice 41 filled in the particle pack 40. The air ejection tube 30 extends to the ejection port 70, and at the ejection port 70, air is ejected.

[0033] [Adjustment of Temperature, Humidity, and Friction] Next, the adjustment of the temperature, humidity, and friction of the supporter 1 will be described.

[0034] When increasing the friction of the surface of the supporter 1 that contacts the object 100, the spray mechanism 20 discharges pure water from the liquid ejection tube 22. As described with reference to FIG. 3, since the spray mechanism 20 discharges pure water onto the fabric 50 from the ejection port 70, the fabric 50 becomes wet with pure water. That is, when increasing the friction of the surface of the bag-shaped fabric 3, the spray mechanism 20 ejects a liquid by the air injected from the third air ejection tube. At this time, since the cohesive force of pure water is large, the contact surface with the object 100 gets wet, and the friction of the surface of the supporter 1 that contacts the object 100 increases.

[0035] When decreasing the friction of the surface of the supporter 1 that contacts the object 100, the air ejection tube 30 discharges dry air. Here, the air ejection tube 30 may be the first air ejection tube. As described with reference to FIG. 3, since the air ejection tube 30 discharges dry air onto the fabric 50 from the ejection port 70, the fabric 50 becomes dry. At this time, as the surface of the supporter 1 that contacts the object 100 dries, the cohesive force due to water decreases, and an air lubricated state is created in the contact area by the discharged air, so the friction of the surface of the supporter 1 that contacts the object 100 decreases.

[0036] When the temperature of the surface of the supporter 1 in contact with the object 100 rises, the conductive strip 10 generates heat by an external power source. The conductive strip 10 generates heat by being energized by the power from an external power source of the supporter 1. That is, when the temperature of the surface of the bag-shaped fabric 3 is lowered, the spray mechanism sprays the liquid by the air injected from the third air ejection tube, and the second air ejection tube ejects dry air. At this time, due to the heat generation of the conductive strip 10, the temperature of the surface of the supporter 1 in contact with the object 100 rises.

[0037] When the temperature of the surface of the supporter 1 in contact with the object 100 is lowered, the spray mechanism 20 sprays the liquid from the liquid ejection tube 22, and the air ejection tube 30 ejects air. As described with reference to FIG. 3, the spray mechanism 20 discharges pure water mist from the ejection port 70 to the fabric 50.

[0038] And, since the air ejection tube 30 discharges dry air from the ejection port 70 to the fabric 50, the discharged pure water mist is in a vaporized state. At this time, the surface of the supporter 1 in contact with the object 100 is cooled by the latent heat of vaporization, so that the temperature of the surface of the supporter 1 in contact with the object 100 is lowered. In addition, the fabric 50 is wetted by the discharged pure water mist, and the temperature of the surface of the supporter 1 in contact with the object 100 may be lowered by the cooling due to the latent heat of vaporization when it dries with the discharged dry air.

[0039] When the humidity of the surface of the supporter 1 in contact with the object 100 is increased, the spray mechanism 20 sprays the liquid from the liquid ejection tube 22. That is, when the humidity of the surface of the bag-shaped fabric is increased, the spray mechanism sprays the liquid by the air injected from the third air ejection tube. As described with reference to FIG. 3, the spray mechanism 20 discharges pure water mist from the ejection port 70 to the fabric 50, so that the fabric 50 is in a state of being wet with pure water. At this time, since the pure water mist stays on the surface of the supporter 1 in contact with the object 100, the humidity of the surface of the supporter 1 in contact with the object 100 is increased.

[0040] When the humidity of the surface of the supporter 1 in contact with the object 100 is to be reduced, the air ejection tube 30 ejects air. That is, when reducing the humidity of the surface of the bag-shaped fabric 3, the second air ejection tube ejects dry air. As described with reference to FIG. 3, since the air ejection tube 30 discharges dry air from the ejection port 70 to the fabric 50, the fabric 50 becomes dry. At this time, as the surface of the supporter 1 in contact with the object 100 dries, the humidity of the surface of the supporter 1 in contact with the object 100 decreases.

[0041] [Usage] Next, the usage method of the supporter 1 will be described. FIG. 4A is a diagram showing an example of using the supporter 1 wound around the arm of the supporter 1 in the embodiment. As shown in FIG. 4A, the supporter 1 may be used, for example, by being wound around a person's arm. The supporter 1 may be wound around the upper arm or the lower arm. The supporter 1 may be wound by bending the long side of the fabric 3 having a rectangular shape when spread. At this time, the supporter 1 may be wound such that the conductive wire body 10, the air ejection tube 30, and the liquid ejection tube 22 are parallel to the direction in which the fabric 3 is wound.

[0042] FIG. 4B is a diagram showing an example of using the supporter 1 wound around the waist of the supporter 1 in the embodiment. As shown in FIG. 4B, the supporter 1 may be used, for example, by being wound around a person's waist. The supporter 1 may be wound by bending the long side of the fabric 3 having a rectangular shape when spread. At this time, the supporter 1 may be wound such that the conductive wire body 10, the air ejection tube 30, and the liquid ejection tube 22 are parallel to the direction in which the fabric 3 is wound.

[0043] [Venturi device] Next, the spray mechanism 20 provided in the supporter 1 will be described. FIG. 5 is a diagram showing the spray mechanism 20 of the supporter 1 in the embodiment. The spray mechanism 20 has a rectangular plate shape and may have a shape of 50 mm × 50 mm × 5 mm. The spray mechanism 20 has a liquid inlet 80, an air inlet 81, a constriction 82, an ejection port 83, and a recess 84.

The constriction 82 is located between the air inlet 81 and the jet outlet 83. The constriction 82 is narrower than the air inlet 81, and the air inlet 81 is narrower than the jet outlet 83. The air inlet 81 is a specific example of an inlet.

[0046] The jet outlet 83 may be a groove with a width of 4 mm. A silicone tube with an outer diameter of 4 mm may be installed at the jet outlet 83.

[0047] The recess 84 is a recess having a rectangular shape in plan view of 30 mm × 25 mm. The recess 84 is connected to the liquid inlet 80 and the jet outlet 83. Cotton containing water may be installed in the recess 84. Further, the recess 84 is a specific example of a liquid holding space.

[0048] The branch flow path 85 branches from a part of the section from the constriction 82 to the jet outlet 83 in the flow path. Further, the branch flow path 85 is connected to the recess 84. The branch flow path 85 supplies the liquid from the recess 84 to the constriction 82 and the jet outlet 83.

[0049] The liquid ejection tube 22 sucks up the liquid injected from the liquid inlet 80 from the constriction 82 by the Venturi effect and ejects the sucked-up liquid from the jet outlet 83.
