Description

The present invention is used to hold a heated pot, frying pan, kettle, oven tray, home bakery pan case, pan-baking mold, and other cooking utensils made of metal, pottery, heat-resistant glass, ceramic, etc. by hand. Regarding insulation holders to protect against heat.

Japanese Unexamined Patent Publication No. 07-275139 Utility Model Registration No. 3109352 Gazette

Patent Document 1 discloses a technique for insulating a portion in contact with a cooking utensil or the like by using a heat insulating material such as a thick contact cloth 11. By using the material of the abutting cloth 11 itself or a material containing a large amount of air such as cotton inside, heat conduction and heat radiation from cooking utensils and the like are alleviated.
Further, Patent Document 2 discloses a technique for improving heat insulating properties by using a heat insulating material such as a finger-insertion heat-resistant sheet sewn on the front surface fabric and a back surface heat-resistant sheet sewn on the back surface fabric.

However, with these conventional techniques, when the whole cooking utensil including the contents is heavy, such as when the amount of cooked food, the amount of hot water or oil is large, or when the cooking utensil itself is heavy, it is heated. When grasping the handle or handle of the cooking utensil, the weight of the entire cooking utensil and the pressure generated by the gripping force when grasping the cooking utensil causes the heat insulating material of the heat insulating holder, such as the inner cotton and the outer contact cloth (patented). In many cases, the heat-resistant sheet (see Patent Document 2) or the heat-resistant sheet provided with great care (see Patent Document 2) is crushed by being pressed to reduce its thickness.

For example, vessels and trays cooked in heater-type or steam-type ovens, bread cases for home bakeries, bread pans, grills, etc. may have a high temperature of 200 ° C to 300 ° C or higher.

In this case, first, from the viewpoint of heat conduction through the substance, the heat insulating material of the heat insulating holder is crushed, and the air having low thermal conductivity contained in the heat insulating material deviates, and the fiber volume of the heat insulating material is increased. As the rate increases and the thermal conductivity increases, the inner cotton, which is the heat insulating material of the heat insulating holder, the outer contact cloth, or the heat-resistant sheet itself becomes a medium for conducting heat, and transfers heat to the fingers. It ends up.

Furthermore, considering the point of heat radiation, the energy of heat radiation is inversely proportional to the square of the distance. Due to the propagation of heat energy by the infrared radiation of, there was also an adverse effect that a considerably large amount of heat was transferred to the hand.
In this way, in the heat insulating holder of the prior art, heat conduction exceeding the heat insulating effect of the heat insulating material of the heat insulating holder is transmitted to the hand by heat conduction through the substance and heat energy propagation by heat radiation, resulting in burns. There was an inconvenience such as doing.

On the other hand, if the thickness of the heat insulating material such as cotton is increased or the surface fabric is thickened, the entire heat insulating holder becomes thick and the finger can be flexibly bent. However, a new problem arises in which it becomes difficult to firmly grasp the cooking utensils.

Alternatively, as in Patent Document 2, if heat-resistant sheets and the like are sewn uniformly over a wide area, the whole body does not deform flexibly even if a finger is bent, and the shape remains flat. There was also the problem of dropping the cooking utensils because they could not grasp the cooking utensils firmly.

Also, even if you apply a heat-resistant sheet uniformly over a wide area, increase the thickness of a heat-insulating material such as cotton, or thicken the surface fabric, after all, if you have a heavy cooking utensil, that part In the vicinity of, there was the inconvenience that the heat insulating material such as cotton and the cloth on the surface were crushed and the thickness was reduced.
In this case, even if the heat-resistant sheets are sewn on top of each other as in Patent Document 2, the distance between the cooking utensil and the fingers becomes short, and the heat-resistant sheet is affected by heat radiation that is inversely proportional to the square of the distance. The effect of reflecting heat radiation can hardly be expected, and although the heat insulating effect is not improved so much, there is also the inconvenience that the material cost is high and the cost is increased.
Further, if the cloth on the surface is made thick, there is a manufacturing problem that the sewing work becomes difficult at the time of sewing.

As described above, in the conventional technique, since sufficient measures have not been taken in consideration of both heat conduction and heat radiation, it is inexpensive, the finger can be flexibly bent, it is easy to grasp an object, and it is effective. It was not possible to provide a heat insulating holder that has a typical heat insulating effect.

Therefore, in the present invention, the above-mentioned inconvenience is avoided while considering the influence on both heat conduction and heat radiation due to the decrease in the thickness of the heat insulating material due to the weight and pressure when the cooking utensil is grasped. Therefore, as in the conventional technique, a thick heat insulating material may be uniformly attached or sewn to the entire outside or inside of the heat insulating holder, or the thickness of the heat insulating material such as cotton or urethane may be applied. To provide a heat insulating retainer that has a high heat insulating effect while allowing flexible operation by making the joints bend and stretch without affecting the bending and stretching, rather than increasing or thickening the surface fabric. With the goal.

In addition, if a thick heat insulating material is uniformly attached or sewn over a large area, not only will the fingers become difficult to bend, but the area and weight of the heat insulating material used will increase, resulting in an increase in cost. It is an object of the present invention to provide a heat insulating holder having a high heat insulating effect at a low cost while suppressing an increase in manufacturing cost.

In order to achieve the above object, the first invention comprises a first finger insertion means for inserting four fingers from the index finger to the little finger and a second finger insertion means for inserting the thumb. A high-density heat insulating material having a predetermined thickness is divided into a plurality of parts at least on the palm side of the first finger insertion means at a position corresponding to the outer edge of the finger or the joint of the finger. Therefore, it is desirable that the heat insulating holder is pasted or sewn.

In this case, the high-density heat insulating material having a predetermined thickness may be the inside of the finger insertion means of the heat insulating holder and the portion that comes into contact with the finger, or the inside of the contact cloth, or the inside of the contact cloth, as long as it is on the palm side. It may be attached or sewn to the outside of the heat insulating holder that comes into contact with the cooking utensil.
Further, the purpose is not limited to the palm side, but at least it is sufficient if it is provided on the palm side, and it may be separately provided on the back side. In this case, depending on the shape of the tray of the oven, the back side of the hand may be exposed to heat, which is useful for protecting the back side of the hand from heat.

In the second invention, the high-density heat insulating material has a substantially rectangular shape, and at least at a position on the palm side of the first finger insertion means, corresponding to the outer edge of the finger or the joint of the finger. It is desirable that the heat insulating holder is divided into a plurality of parts and pasted or sewn.
In the third invention, in the first or second invention, the high-density heat insulating material is divided into a plurality of parts so that the joint portion of the finger becomes the boundary line of each high-density woven material. It is desirable that the insulation holder is attached or sewn.
In the fourth invention, the high-density heat insulating material is divided into a plurality of parts and attached or attached so that the position of the second joint from the index finger to the little finger is the boundary line of each high-density woven material. It is desirable that the insulation holder is sewn.

As a result, in addition to the certain flexibility of the high-density woven material itself, the boundary of each high-density woven material is arranged so as to be located at the joint portion, which hinders the bending and stretching of the knuckles. It is possible to effectively suppress heat from cooking utensils and the like.
For example, from the index finger to the little finger, a total of two pieces, one on the fingertip side and one toward the base of the finger, with the vicinity of the second joint as the center line, are pasted or sewn substantially parallel to each other. It is possible to effectively suppress heat from cooking utensils and the like without hindering the bending and stretching of joints.
Alternatively, from the index finger to the little finger, a total of eight rectangular materials such as two rectangular materials may be attached or sewn to each finger with the vicinity of each joint of each finger as the center line.

In this case, since it is only necessary to attach or sew at least two belts or a tape-shaped high-density woven material having a vertically long substantially rectangular shape, the manufacturing cost can be suppressed.

A fifth invention prevents the high-density heat insulating material from changing in thickness due to pressure or the like when a cooking utensil or the like is gripped by weaving a spun yarn composed of a natural material or a chemical fiber as a material. It is desirable that it is a high-density woven material configured as described above.
According to the sixth aspect of the present invention, the width of the high-density woven fabric material is, for example, 25 to 60 mm in a portion where the tip of the index finger or the middle finger abuts on the second joint of the finger, according to the length of the portion. Is desirable.
The thickness of the high-density woven material can be appropriately adjusted according to the heat-resistant temperature to be set, and the width can be adjusted according to the size of the hand.

According to the present invention, the finger can be flexibly bent, and the thickness (and distance) of the portion where the heat insulating holder comes into contact with the cooking utensil does not easily change due to the weight of the cooking utensil or the pressure when grasping. Thereby, it is possible to provide a heat insulating holder that can effectively protect the fingers from the hot cooking utensil.

Further, according to the configuration of the present invention, it is possible to exhibit a high heat insulating effect with an inexpensive material.
Further, by utilizing the technique of the present invention, it is possible to provide a heat insulating holder that is flexible and has high heat insulating properties not only when handling cooking utensils but also when handling high temperature objects at various manufacturing sites. Various uses are possible.

<Explanation of terms>
◇ Cooking utensils refer to all cooking utensils such as pots, kettles, heater-type or steam-type oven-cooked vessels and trays, home bakery bread cases, bread pans, and grills.
◇ Pot-holder is a general term for heat-insulating holders that have heat insulating properties so that you can safely hold hot cooking utensils such as pots by hand. The tool of.
◇ The shape of the pot holder is a shape with two finger openings, one for the thumb and one for the remaining four (hereinafter referred to as "mittens type"), and a shape that imitates the mouth of an animal such as a frog (hereinafter referred to as "pakupaku type"). ) There is a five-finger type in which five fingers are divided into separate finger slots.

◇ A heat insulating material is a material that suppresses heat conduction and heat radiation and has heat insulating properties. In addition to the low-density heat insulating material and high-density heat insulating material described later, it is a general term for materials having heat insulating properties, including heat-resistant sheets and heat-reflecting sheets.
◇ Low-density heat insulating material means a heat insulating material that is composed of a relatively low-density material such as cotton and is configured to contain a large amount of air.
-The high-density heat insulating material is a material having heat insulating properties used in the present invention, and the material is crushed by the weight and pressure when holding a cooking utensil, etc., and the distance from the high temperature cooking utensil becomes short. Any material having a predetermined density and having a strength to prevent it from being stowed may be used.
As an example of a high-density heat insulating material, a spun yarn composed of a natural material or a chemical fiber is woven as a material so as to prevent the thickness from changing due to pressure when gripping a cooking utensil or the like. A high-density woven material having the thickness of can be used. The fiber volume fraction, which indicates the fiber content per unit volume in the high-density woven material, can be in the range of about 20 to 90%, but can be freely adjusted depending on the weaving method and the material, and is not limited to this value.
Alternatively, as an example of the high-density heat insulating material, a resin material such as plastic, urethane, epoxy resin, polyphenylene sulfide resin, a rubber material such as natural rubber or urethane rubber can be used.

◇ In addition to convection, heat conduction and heat radiation are other mechanisms for heat transfer. Heat conduction is the transfer of heat through a substance such as the material of a heat insulating holder, and heat radiation is the propagation of heat energy by emitting heat energy as electromagnetic waves from a high-temperature object. .. In the heat insulating holder, a thick material such as a quilt is used as the skin material in order to suppress heat conduction by containing air and to suppress heat radiation by taking a distance.

◇ Thermal conductivity is an index showing the ease of heat transfer, and is displayed in units of W / m · K. The thermal conductivity varies depending on the substance, and is generally high for metal, 83.5 for iron, 0.15 to 0.25 for wood, and the fiber material is 2.88 for unwoven fiber alone. It is known that wool (hair) is 0.48, polyester is 1.26, acrylic is 1.02, and in the case of air, the thermal conductivity is 0.024, which is very small (The Textile Machinery Society of Japan). Journal 39, T-184).
Insulation materials are often composed of some fibrous material. The thermal conductivity of the fiber material differs depending on the type of fiber, and in the case of wool (hair), it varies slightly depending on the weaving method, but according to one example, when the fiber volume ratio is 11%, the thermal conductivity is high. While it is 0.06, when the fiber volume ratio is 29%, the thermal conductivity is 0.09. In the case of cotton, the thermal conductivity is 0.11 when the fiber volume ratio is 12%, whereas the thermal conductivity is 0.16 when the fiber volume ratio is 23%. ..
In the case of polyester, according to one example, when the fiber volume ratio is 21%, the thermal conductivity is 0.08, whereas when the fiber volume ratio is 40%, the thermal conductivity is 0.14. ing.

In this way, the thermal conductivity tends to increase as the fiber volume ratio of any fiber increases. Therefore, as a heat insulating material, the fiber volume ratio is slightly suppressed so as to contain air in between. Density insulation materials are often used.
On the other hand, if the fiber volume ratio is reduced, the heat insulating material is crushed by the pressure applied to the heat insulating material when the cooking utensil or the like is gripped, and the influence of heat conduction and heat radiation due to the decrease in thickness is rather increased. Occurs.
Therefore, paying attention to the fact that the thermal conductivity is only about 0.1 to 0.2 even if the fiber volume ratio is increased, in the present invention, the heat insulating material made of a general heat insulating material or a low density heat insulating material is maintained. Effectively combine high-density heat insulating materials with the ingredients to improve heat insulating properties.

◇ As a typical example of thermal radiation, there is infrared radiation, which is an electromagnetic wave having a wavelength of about 780 nm to 1 mm.
◇ Infrared radiation is divided into "near infrared", "middle infrared" and "far infrared" according to the wavelength.
◇ Radiation rate is the ratio when the energy of light emitted by an object by thermal radiation (radiation brightness) is set to 1 when the energy of light emitted by a blackbody at the same temperature (blackbody radiation) is 1.
It is known that the emissivity of a substance depends on the wavelength range of infrared rays emitted as thermal energy.
Cooking utensils made of metals such as iron or cast iron, pottery, heat-resistant glass, ceramics, etc. become more active in infrared radiation as the temperature rises, and the emissivity changes depending on the material.
Here, iron, cast iron, iron alloy, pottery, heat-resistant glass, ceramic, etc. have high emissivity. For example, aluminum has an emissivity of about 0.1, whereas cast iron, pottery, heat-resistant glass, etc. have high emissivity. It is known that the emissivity is relatively high at 0.9 in one example, although it depends on the temperature. In particular, ceramic has a high emissivity of 0.94 and is therefore used as a heater material.

◇ Regarding the relationship between infrared radiation and distance, the energy density decreases in inverse proportion to the square of the distance. "Distance" is one of the important parameters for reducing infrared radiation.

Hereinafter, examples of the heat insulating holder of the present invention will be described.
The shape of the heat insulating holder in the description is merely an example, and can be applied to various shapes of the heat insulating holder such as a crisp type, a mittens type, and a five-finger type.

1. 1. Outline of the conventional heat insulating holder First, the configuration of the conventional general heat insulating holder will be described with reference to FIG. 1.
As shown in FIG. 1, the conventional general heat insulating holder has a structure in which a low-density heat insulating material 3 such as cotton is sealed between the contact cloth 1 on the front surface and the contact cloth 2 on the back surface. ..
As the abutting cloth, a cloth having a heat insulating material enclosed therein, such as a quilted cloth, may be used.
In the case of the conventional technique, in order to improve the heat insulating effect, there is no choice but to increase the overall thickness of the contact cloth and the heat insulating material inside, and if the thickness exceeds a certain level, flexible operation becomes impossible. There was a limit to the increase.
For this reason, there is a disadvantage that the contact cloths 1 and 2 and the low-density heat insulating material 3 inside are crushed by the pressure applied when holding a heavy cooking utensil, and a sufficient heat insulating effect cannot be maintained.

2. 2. Insulation holder of the present invention 2-1. Example 1
Next, the heat insulating holder of the present invention will be described with reference to FIG. 2 (1).
FIG. 2 (1) is a diagram showing an embodiment of the heat insulating holder 100 of the present invention, and is a diagram showing a configuration of a portion that comes into contact with a finger. When actually used, the abutting cloth (not shown) covering the back of the hand configured on the back side of the heat insulating holder 100 of FIG. 2 is folded back and used in the manner shown in FIG.

According to FIG. 2 (1), in the heat insulating holder 100 of the present invention, the first finger insertion means 110 for inserting four fingers from the index finger to the little finger and the second finger insertion means 120 for inserting the thumb. It is equipped with. Further, the high-density heat insulating materials 10A and 10B are attached or sewn to the portion of the first finger insertion means 110 that abuts on the palm side.
Here, "pasting" includes not only pasting with an adhesive or the like, but also heating and fusing, and "sewn" includes directly sewing a high-density heat insulating material. It also includes a case where a storage area knitted with a thread or the like is provided inside the abutting cloth and the high-density heat insulating material is held so as to be confined in the storage area.

Note that FIG. 2 (1) shows an embodiment in which the high-density heat insulating material 10 is provided on the portion of the finger that comes into contact with the palm side, but the inside of the contact cloths 1 and 2 of the heat insulating holder 100 is shown. Alternatively, it may be attached or sewn to a portion of the contact cloth 1 or 2 in contact with the cooking utensil (outside of the heat insulating holder 100).
When it is provided on the outside, it is preferable to knit a spun yarn of a heat-resistant natural fiber such as cotton or linen. On the other hand, when it is provided on the inside, it is possible to use a cloth in which the outer contact cloth is made of natural fibers such as cotton and linen and the spun yarn of chemical fibers is woven inside.

Here, in FIG. 2 (1), the high-density heat insulating materials 10A and 10B have a belt-like or tape-like shape, and both are attached or sewn substantially in parallel with each other.
The boundary between the high-density heat insulating material 10A and 10B is generally pasted or sewn at a position corresponding to the second joint portion of the four fingers from the index finger to the little finger.
As a result, in order to sufficiently improve the heat insulating property, even if the high-density heat insulating materials 10A and 10B are made of thick, hard and hard-to-deform materials, the movement of bending the fingers to grasp the object is flexible. Can be done.
Although the position of the second joint differs for each finger, there is no big difference when the position of the second joint when the finger is bent is viewed from the side. Therefore, for example, the position of the second joint from the index finger to the little finger is used. If you set it to an average position, you can flexibly bend and stretch your fingers.

Further, the second finger-insertion means 120 for inserting the thumb also has the same configuration as that of the high-density heat insulating materials 10C and 10D, but this is the first finger-insertion means 110 and the second. By making the configuration of the finger insertion means 120 the same, such symmetry is merely ensured so that any finger can be inserted.
For example, the second finger-insertion means 120 for inserting the thumb is made smaller than the first finger-insertion means 110 so as to correspond to the shape of the thumb, and the high-density heat insulating materials 10C and 10D are made accordingly. The shape of the can be adjusted as appropriate. Alternatively, the high-density heat insulating material 10 having a vertically long substantially rectangular shape like a belt or a tape may be used with only one piece according to the thumb without using two pieces of 10C and 10D.

As an example, the high-density heat insulating material 10 is configured by weaving a spun yarn composed of a natural material or a chemical fiber as a material to prevent the thickness from changing due to pressure or the like when gripping a cooking utensil or the like. , A high-density woven material having a predetermined thickness can be used.
As a high-density woven material having a predetermined thickness, inexpensive tape materials for handicrafts and materials for belts sold at handicraft stores and 100-yen uniform shops can be used, and the cost can be suppressed. Will be.

The high-density woven material may be one in which fibers of natural materials such as cotton, linen, and pulp are woven at high density, or one in which chemical fibers such as acrylic, nylon, polyester, and polypropylene are woven.
In addition, if a fiber made by twisting a large number of fine threads is used as the fiber used as a material, a higher density woven fabric can be created, and it is difficult to be deformed by the weight of the cooking utensil or the pressure when the cooking utensil is gripped. Become.
It is desirable that the thickness has a certain thickness in order to secure heat insulation, but it also changes depending on the material and how much flexibility is secured, and considering flexibility, it is desirable to be about 1 to 7 mm. Not limited to this.
The fiber volume fraction, which indicates the fiber content per unit volume, can be in the range of about 20 to 90%, but can be freely adjusted depending on the weaving method and material, and is not limited to this value.

The three original textures of woven fabrics include plain weave, twill weave, and satin weave. Twill weave has excellent elasticity, and satin weave tends to be thick and flexible.
Twill weave or satin weave is suitable for easy bending and stretching of fingers and ensuring flexibility, but plain weave can also be used by appropriately adjusting the fibers used.
As a weaving method to give thickness, a multi-layer structure may be used. For example, by using a binding weave or a traditional Chinese bookbinding weaving, weaving in two layers, three layers, four layers, and so on, 1 to 7 mm. It is possible to secure a certain thickness.

Further, if the material of the high-density heat insulating material 10 is a material that prevents the material from being crushed by the weight and pressure when holding the cooking utensil and the like, and the distance between the high-temperature cooking utensil and the fingers becomes short. Anything may be used, and in addition to the high-density woven material, a resin material may be attached, or a storage area knitted with a thread or the like may be provided inside the abutting cloth to wrap the resin material. ..
In this case, the shape of the high-density heat insulating material 10 may be a rectangular shape or the like as shown in FIGS. 2 (2) and 3 (2) described later so that the finger can be flexibly bent and stretched. desirable.

As described above, since the high-density heat insulating material 10 having a predetermined thickness of the present invention is densely composed of the material, the weight of the entire cooking utensil including the cooked dish and the pressure generated by the grip strength when grasping the food are used. Since it is not crushed by, the heat insulating effect can be surely exhibited.

2-2. Example 2
Next, a modified example of FIG. 2 (1) will be described with reference to FIG. 2 (2).
As shown in FIG. 2 (2), the high-density heat insulating material 10 made of a high-density woven material may be configured to have a rectangular shape divided for each finger. The rectangular shape is an example, and various shapes such as a square, a rectangle, a parallelogram, and an ellipse can be adopted (hereinafter referred to as "substantially rectangular shape").
As a result, even if the angle at which the joint is bent differs for each finger, it is possible to respond more flexibly. Further, although the boundary between the high-density heat insulating materials 10A and 10B is configured to draw the same line with each finger in the figure, the position may be adjusted according to the position of the joint of each finger.

In this case, the second finger-insertion means 120 for inserting the thumb is manufactured to be smaller than the first finger-insertion means 110 so as to correspond to the shape of the thumb, and accordingly, the high-density heat insulating material 10C is used. The shape of the 10D can also be adjusted as appropriate. Alternatively, one (or one rectangular or the like) high-density heat insulating material 10 having a vertically long substantially rectangular shape like a belt or tape can be fitted to the thumb without using two of 10C and 10D. ) May be completed.

2-3. Example 3
Alternatively, as shown in FIG. 2 (3), a high-density heat insulating material 10 having a vertically long substantially rectangular shape like a belt or a tape in the direction from the base of the finger toward the fingertip is used according to the position of the finger. Is also good. In this case, the boundary corresponding to the position of the joint is not formed, but since the high-density heat insulating material 10 is divided and attached to each finger, it is necessary to flexibly respond to the bending condition of each finger to grasp an object. Can be done.

Further, the place where the high-density heat insulating material 10 is arranged is not limited to the palm side, but at least it is sufficient if it is provided on the palm side, and is separately provided at a position corresponding to the finger on the back side. It doesn't matter if you do. Depending on the shape of the tray of the oven, the back side of the hand may be exposed to heat, which is useful for protecting the back side of the hand from heat.

As described above, at least on the palm side of the first finger insertion means, the high-density woven material is divided into a plurality of parts and pasted or sewn at the positions corresponding to the fingers or the joints of the fingers. It is possible to provide a heat insulating holder that can flexibly grasp an object while ensuring heat insulating properties.
Regarding the width of the high-density woven material, when used in such a manner that the boundary comes to the position of the joint as shown in FIGS. 2 (1) and 2 (2), the width from the tip of the index finger or the middle finger to the second joint of the finger. For example, a knuckle having a width of about 25 mm to 60 mm can be used according to the length, and a knuckle having a width of about 10 to 20 mm can be used to match the width of the finger as shown in FIG. 2 (3). Can be used.

2-4. Example 4
Next, a further modification will be described with reference to FIG.
FIG. 3 is a diagram showing an example of a mittens-type heat insulating holder.
According to FIG. 3 (1), in the heat insulating holder 100 of the present invention, the first finger insertion means 110 for inserting four fingers from the index finger to the little finger and the second finger insertion means 120 for inserting the thumb. It is equipped with.
Further, the high-density heat insulating materials 10A and 10B are attached or sewn to the portion of the first finger insertion means 110 that abuts on the palm side.

Here, in FIG. 3 (1), the high-density heat insulating materials 10A and 10B have a vertically long substantially rectangular shape like a belt or a tape, and both are pasted or sewn substantially in parallel with each other. Has been done.
The boundary between the high-density heat insulating material 10A and 10B is generally pasted or sewn at a position corresponding to the second joint portion of the four fingers from the index finger to the little finger.
As a result, in order to sufficiently improve the heat insulating property, even if the high-density heat insulating materials 10A and 10B are made of thick, hard and hard-to-deform materials, the operation of bending the finger and grasping the object is flexible. Can be done.

In this case, the high-density heat insulating materials 10C and 10D in the second finger insertion means 120 for inserting the thumb may be made of one rectangular or the like part according to the thumb, instead of using two parts. not.

Next, a modified example of FIG. 3 (1) will be described with reference to FIGS. 3 (2) and 3 (3).
As shown in FIG. 3 (2), the high-density heat insulating material 10 may be configured to have a rectangular shape or the like divided for each finger. As a result, even if the angle at which the joint is bent differs for each finger, it is possible to respond more flexibly. Further, although the boundary between the high-density heat insulating materials 10A and 10B is configured to draw the same line with each finger in the figure, the position may be adjusted according to the position of the joint of each finger.

In this case, the second finger-insertion means 120 for inserting the thumb is manufactured to be smaller than the first finger-insertion means 110 so as to correspond to the shape of the thumb, and accordingly, the high-density heat insulating material 10C is used. The shape of the 10D can also be adjusted as appropriate. Alternatively, instead of using the two parts of 10C and 10D, the high-density heat insulating material 10 having a vertically long substantially rectangular shape like a belt or tape can be used with one rectangular part or the like according to the thumb. It doesn't matter.

Alternatively, as shown in FIG. 3 (3), a high-density heat insulating material 10 having a vertically long substantially rectangular shape like a belt or a tape in the direction from the base of the finger toward the fingertip is used according to the position of the finger. Is also good. In this case, the boundary corresponding to the position of the joint is not formed, but since the high-density heat insulating material 10 is divided and pasted or sewn for each finger, the object can be flexibly adapted to the bending and stretching of each finger to some extent. You can grab it.

Further, also in the mittens-type heat insulating holder of FIG. 3, the high-density heat insulating material 10 may be attached or sewn at a position corresponding to the finger on the back side of the hand or a position in contact with the back of the hand.

<Usage state of the present invention in Examples 1 to 3>
Next, the usage states in Examples 1 to 3 of the present invention will be described with reference to FIGS. 4 and 5.
FIG. 4 is a diagram showing an example of the appearance after completion in the configuration example of FIG. 2, and is a diagram showing an embodiment of an embodiment when the heat insulating holder 100 of FIG. 2 is used. This is an example of a case where it is configured as a so-called crisp type heat insulating holder.
When the portion (not shown) that covers the portion of the back of the hand configured on the back side of the heat insulating holder 100 of FIG. 2 is folded back, the mode as shown in FIG. 4 is obtained.

FIG. 5 is a diagram showing an embodiment of a usage state, and is a diagram showing a state in which the heat insulating holder 100 after completion in the configuration example of FIG. 2 is attached to the hand.
The first finger-insertion means 110 is shown to insert four fingers from the index finger to the little finger, and the second finger-insertion means 120 is shown to insert the thumb.
In this case, between each finger and the hot cooking utensil, a high-density heat insulating material such as a contact cloth, cotton integrated with the contact cloth, or a high-density woven material is used. There is a density heat insulating material 10, etc., and the heat insulating effect can be exhibited.

FIG. 6 is a diagram showing a state in which the heat insulating holder 100 after completion in the configuration example of FIG. 2 is attached to the hand, and is a diagram showing the positional relationship of the high-density heat insulating material 10 that comes into contact with the finger.
According to FIG. 6, in the first finger insertion means 110 for inserting four fingers from the index finger to the little finger, the boundary between the high-density heat insulating materials 10A and 10B is exactly the average position of the second joint such as the index finger. It can be seen that it is configured to come to the surface and can flexibly respond to the bending and stretching of the fingers from the index finger to the little finger.
Further, in the second finger insertion means 120 for inserting the thumb, the boundary between the high-density heat insulating material 10C and 10D is configured to be at the position of the first joint or the second joint of the thumb, and the thumb is bent and stretched. It can be seen that it can respond flexibly to.

Although FIG. 6 shows an example in which a high-density heat insulating material having a predetermined thickness is provided on the inside of the finger insertion means of the heat insulating holder and in the portion in contact with the finger, the inside of the contact cloth or the inside of the contact cloth is shown. It may be attached or sewn to the outside of the heat insulating holder that comes into contact with the cookware.

2-5. Example 5
Next, further modifications will be described with reference to FIGS. 8 to 10.
In Example 5, at least, the palm side of the first finger insertion means was divided into a plurality of parts and pasted or sewn at positions corresponding to the outer edges of the fingers or the joints of the fingers. Is the same as in Examples 1 to 4.
FIG. 8 is a diagram showing an embodiment of the heat insulating holder 100 of the present invention when three high-density heat insulating materials are used, and is a diagram showing a configuration of a portion that comes into contact with a finger.
FIG. 8 is one of the modifications of FIG. 2 (1) of the first embodiment, and has a configuration in which 10B and 10C of FIG. 2 (1) are combined into one. Therefore, for convenience of explanation, the reference numeral of the central high-density heat insulating material is described as "10B, 10C".

Here, in FIG. 8, the high-density heat insulating material 10A has a slightly vertically long substantially rectangular shape like a belt or tape, and the high-density heat insulating materials 10B and 10C have a substantially rectangular shape. Various substantially rectangular shapes such as a parallelogram and an ellipse can be adopted. For example, the four corners of a substantially rectangular shape do not have to be 90 degrees, and may be curved.

According to FIG. 8, the boundary (arrow a) between the high-density heat insulating material 10A and the high-density heat insulating materials 10B and 10C is located at a position generally corresponding to the second joint portion of the four fingers from the index finger to the little finger. It can be seen that they are pasted or sewn so as to be.
Further, the boundary (arrow b) between the high-density heat insulating material 10D and the high-density heat insulating materials 10B and 10C is pasted or sewn so as to be at a position corresponding to the second joint portion of the thumb. You can see that.
With these configurations, it is possible to flexibly perform the operation of bending a finger and grasping an object.

Unlike the first embodiment of FIG. 2 (1), the high-density heat insulating materials 10B and 10C in the center are made of one material, and therefore, at first glance, they are difficult to bend when inserting a hand and grasping an object. It seems like that. However, since the knuckles are not bent but are bent at the substantially central portion of the palm (CT in FIG. 10), there is no particular problem even if the boundary portion of the high-density heat insulating material is not provided in this portion. In short, it is sufficient to provide the boundary portion of the high-density heat insulating material corresponding to the joint portion of the finger.

FIG. 9 is one of the modifications of FIG. 8, and is a diagram showing an example of a mode in which the portions of the high-density heat insulating materials 10B and 10C in the center of FIG. 8 are divided into two on the left and right. By dividing the high-density heat insulating material 10B and 10C into two parts on the left and right, the rigidity or strength of this part against bending is reduced, and it is easy to bend when bending at the substantially central part of the palm (CT in FIG. 10). There is an effect. Similarly, it is also possible to adopt a configuration in which this part is disassembled into three, four, and so on.

In FIG. 9, if the width W1 seen from the longitudinal direction of the high-density heat insulating material 10A and the width W3 seen from the longitudinal direction of the high-density heat insulating materials 10B and 10C are the same, the same material can be used. can. For example, a tape-shaped high-density heat insulating material having a predetermined width is cut into an appropriate length and used.

FIG. 10 is a diagram showing a state in which the heat insulating holder 100 after completion in the configuration examples of FIGS. 8 and 9 is attached to the hand, and is a diagram showing the positional relationship of the high-density heat insulating material 10 that comes into contact with the finger. ..
According to FIG. 10, in the first finger insertion means 110 for inserting four fingers from the index finger to the little finger, the boundary between the high-density heat insulating material 10A and the high-density heat insulating materials 10B and 10C is exactly the index finger or the like. It is configured so that it comes to the average position of the second joint, and it can be seen that it can flexibly respond to the bending and stretching of the fingers from the index finger to the little finger.

Further, in the second finger insertion means 120 for inserting the thumb, the boundary between the high-density heat insulating material 10B and 10C and the high-density heat insulating material 10D is configured to be at the position of the first joint or the second joint of the thumb. It can be seen that it can flexibly respond to the bending and stretching of the thumb.
Although FIG. 10 shows an example in which a high-density heat insulating material having a predetermined thickness is provided on the inside of the finger insertion means of the heat insulating holder and in contact with the finger, the inside of the contact cloth or the inside of the contact cloth is shown. It may be attached or sewn to the outside of the heat insulating holder that comes into contact with the cookware.

Regarding the width W1 of the high-density woven fabric material 10A, for example, when the high-density woven fabric material 10A in FIGS. 8 and 9 is used in such a manner that the boundary comes to the joint position (arrow a), the index finger or the index finger or the like. Depending on the length from the tip of the middle finger to the second joint of the finger, for example, one having a width of about 25 mm to 60 mm can be used.
Further, the width W2 of the high-density woven fabric materials 10B and 10C of FIGS. 8 and 9 is adjusted to the length from the second joint of the index finger or the middle finger to the second joint of the thumb when viewed in the vertical direction of the figure. For example, a material having a width of about 60 to 100 mm can be used.

Further, as for the width W3 of the high-density woven fabric materials 10B and 10C of FIG. 9, for example, those having a width of about 25 to 60 mm can be used according to about half of the length from the index finger to the little finger.
Further, as for the lateral length L in the figure of the high-density woven fabric material 10A, for example, a material having a width of about 60 to 110 mm can be used according to the length from the index finger to the little finger.

2-6. Example 6
Next, further modifications will be described with reference to FIGS. 11 to 13.
In Example 6, at least on the palm side of the first finger insertion means, the outer edge of the finger or the position corresponding to the joint of the finger was divided into a plurality of parts and pasted or sewn. Is the same as in Examples 1 to 5.

FIG. 11 is a view showing the whole of FIG. 2 (3) of the third embodiment, and is a belt-like or tape-shaped vertically long rectangular shape in the direction from the base of the finger toward the fingertip according to the position of the finger. It is a figure which shows an example of the case where the high-density heat insulating material 10 which has a substantially rectangular shape is used.
In this example, the boundary corresponding to the position of the joint is not formed between the high-density heat insulating materials 10, but the high-density heat insulating materials 10A to 10D are divided and pasted for each finger through the gaps. Therefore, the rigidity or strength against bending can be appropriately suppressed, and it is possible to grasp an object flexibly to some extent according to the bending condition of each finger.

In this case, high-density heat insulating materials 10A to 10D so that the first finger insertion means 110 for inserting four fingers from the index finger to the small finger and the second finger insertion means 120 for inserting the thumb can be handled without distinction. The lengths may be substantially the same, or the first finger-insertion means 110 for inserting four fingers from the index finger to the small finger and the second finger-insertion means 120 for inserting the thumb are specified. , Except for the part that comes into contact with the thumb (for example, 10A), the parts 10B to 10D may be kept up to half the length in the figure.

FIG. 12 is one of the modifications of FIG. 11, and is a diagram showing an example of a case where the high-density heat insulating materials 10A and 10B are made into one part and the high-density heat insulating materials 10C and 10D are made into one part. By dividing the high-density heat insulating material into two parts on the left and right, the rigidity or strength of this part against bending is lowered, and there is an effect that it becomes easier to bend when bending at the joint part of the finger or the substantially central part of the palm.
FIG. 13 is a diagram showing a state in which the heat insulating holder 100 after completion in the configuration examples of FIGS. 11 and 12 is attached to the hand, and is a diagram showing the positional relationship of the high-density heat insulating material 10 that comes into contact with the finger. ..
In FIG. 13, the boundary between the high-density heat insulating materials corresponding to the joint portion of the finger is not seen, but since the corresponding boundary is provided between the fingers, the high-density heat insulating material is not rigid against bending. The strength can be moderately suppressed, and it is possible to grasp an object flexibly to some extent according to the bending condition of each finger.

Although the examples of Examples 1 to 6 have been described above, the present invention is not limited to this, and various modified examples can be applied.
In all the examples, the gap between the high-density heat insulating materials can be adjusted as appropriate. For example, about 1 to 5 mm can be adopted, but it is sufficient if the materials are divided, and they are almost in close contact with each other. It doesn't matter.

As for the width of the high-density woven material, as shown in FIG. 11, when matching the width of the finger, for example, a material having a width of about 10 to 20 mm can be used. Further, in the case of grouping by two fingers as shown in FIG. 12, for example, one having a width of about 20 to 40 mm can be used.

3. 3. Measurement of Effect (Experimental Results) Next, the heat insulating effect of the heat insulating holder 100 of the present invention will be described with reference to FIG. 7.
FIG. 7 is an example of experimental results showing the heat insulating effect of the technique of the present invention.
As cooking utensils, an oven tray (item No. 1), an iron pan (item No. 2), and a baking dish (item No. 3) were used. The material of the oven tray and iron pan was iron, and the material of the gratin dish was ceramic, both of which had a high emissivity of 0.9 or more. This is because by using a material having a large heat radiation, the difference in heat insulating effect becomes noticeable.

In addition, the measurement results show the results when a high-density woven material in which polyester fibers having a thickness of 2 mm are woven is used as the high-density heat insulating material 10.
In addition, similar results are obtained when fibers made of natural materials such as cotton and other chemical fibers such as acrylic and nylon are used.
It has been found that the heat insulating effect increases as the thickness increases to 4 mm, 6 mm, 8 mm, and 10 mm, but a sufficient heat insulating effect is obtained if the thickness is about 1 to 4 mm. On the other hand, if it is made too thick, the flexibility will decrease, so a thickness of about 2 to 4 mm is preferable from the balance of flexibility and heat insulating effect, but it is about 1 to 7 mm depending on the setting of the heat resistant temperature. The thickness can be adjusted in the range.

In the experiment, the surface temperature of the handle of the cooking utensil, the surface temperature of the high-density heat insulating material 10 or the finger after 5 seconds of gripping, and the surface temperature of the finger after 10 seconds of gripping, respectively. It was measured.
Since there are not many scenes where it is necessary to hold the cooking utensil for 15 seconds or more, the temperature does not continue to rise until a certain time elapses, such as 15 seconds and 30 seconds after gripping, although not shown. It has been found that the temperature rises until 1 to 2 minutes after the heat is dissipated from the cooking utensils.

FIG. 7 (1) is data showing the measurement results of the conventional heat insulating holder (hereinafter abbreviated as “conventional product”), and the numerical values of the temperature rise after 5 seconds and 10 seconds after gripping were also calculated.
FIG. 7 (2) is data showing the measurement results of the heat insulating holder 100 (hereinafter abbreviated as “invention product”) of the present invention, and the numerical values of the temperature rise after 5 seconds and 10 seconds after gripping were also calculated. ..

According to the measurement result of the conventional product of FIG. 7 (1), for example, in the case of the tray of the oven of No. 1 (surface temperature 222 ° C.), the measured value of the surface temperature of the finger is 56 after 10 seconds of gripping. It can be seen that the temperature rises to ℃. In this case, although there are some differences depending on how each subject feels, the general situation is that they are too hot to hold.
This is because the low-density heat insulating material such as the contact cloth and the cotton inside is crushed by the pressure when gripping the cooking utensil and loses its thickness, and the distance from the cooking utensil becomes short, so that it is from a high temperature cooking utensil. This is due to the strong influence of heat conduction and heat radiation.

On the other hand, according to the measurement result of the invention of FIG. 7 (2), in the case of the tray of the oven of No. 1 (surface temperature 222 ° C.), the measured value of the surface temperature of the finger is very small even after 10 seconds of gripping. The temperature was as low as 32 ° C, and the result was that all the subjects "did not feel much heat".
This is because even if the low-density heat insulating material such as the contact cloth and the cotton inside is crushed to some extent by the pressure when the cooking utensil is gripped, the high-density heat insulating material 10 is not crushed and the high-temperature cooking utensil or the like is used. This is because the temperature rise due to heat conduction and heat radiation is effectively suppressed by securing the distance.

Further, comparing the numerical values of the temperature rise, which is the difference between the temperature after 5 seconds of gripping and the temperature after 10 seconds of gripping in FIGS. 7 (1) and 7 (2), the temperature rises by 10 to 13 ° C. in the conventional product. On the other hand, in the case of the invention, the temperature rises only 3 to 5 ° C., and in particular, in the case of a cooking utensil that needs to be kept for a long time, it can benefit from a large heat insulating effect.
For example, when removing the bread immediately after baking from the bread case of a home bakery, the bread does not easily come off from the screw part that kneads the bread at the bottom of the bread case, so shake the bread case many times and take time to pour the bread. Since it is necessary to remove it, the effect of the present invention can be further realized.

FIG. 7 (3) is a table comparing the performance of the conventional product and the invention product based on the results of temperature measurement as absolute values.
According to FIG. 7 (3), in the tray of the oven of No. 1, while the surface temperature is 222 ° C., the surface temperature of the finger after 5 seconds of gripping is 43 ° C. in the conventional product. On the other hand, it can be seen that the temperature of the invention product is 29 ° C, which is lower than that of human skin. Further, from this, the performance difference between the conventional product and the invention product is 14 ° C.
In addition, the surface temperature of the finger 10 seconds after gripping is 56 ° C, which is a high temperature that is difficult to hold in the conventional product, whereas it is 32 ° C in the invention product, which is still lower than that of human skin. You can see that it has been done. Further, from this, the performance difference between the conventional product and the invention product is 16 ° C.

In addition, according to the measurement results of the iron pan and gratin dish of No. 2, the performance difference between the conventional product and the invention product is 10 to 14 ° C after 5 seconds of gripping and 15 to 17 ° C after 10 seconds of gripping. It can be seen that the difference increases as time goes by.

In the conventional product, in an attempt to generate a heat insulating effect by including a large amount of air in the heat insulating material, the fiber volume ratio of the heat insulating material is suppressed, so that the pressure applied to the heat insulating material when gripping a cooking utensil or the like causes The heat insulating material was crushed and the thickness was reduced, so that the effects of heat conduction and heat radiation were rather large.
On the other hand, in the present invention, emphasis is placed on the state when gripped, and cooking is performed by effectively combining a high-density heat insulating material with a heat insulating holder made of a general heat insulating material or a low-density heat insulating material. By ensuring a certain thickness even when pressure is applied when gripping an instrument, it is possible to suppress the effects of heat conduction and heat radiation.

In addition, while using a thick high-density heat insulating material, the high-density heat insulating material is divided into multiple parts and placed at positions corresponding to the outer edges of the fingers and the joints of the fingers to ensure flexibility. Was done.
In addition, by using a high-density heat insulating material that is thick and has a predetermined area, it prevents heat from being transferred at points, exerts the effect of dispersing heat over the area, and effectively suppresses heat conduction. We were able to.

4. Summary As described above, when a cooking utensil made of a material with high radiation coefficient is used, the temperature rise due to heat conduction and heat radiation is remarkable in the conventional product, but according to the present invention, the temperature can be increased. It was found that the longer the time for holding the cooking utensils, the more the heat insulating effect was exhibited, and the temperature rise due to heat conduction and heat radiation was effectively suppressed.

The heat insulating holder of the present invention can be used not only for holding cooking utensils and the like, but also for holding things that become hot in the manufacturing process of various things.
