  Thus, the plate-like body 11 can be composed of a plurality of parts such as the frame body 21 and the base plate 22. Here, if the plate-like body 11 is composed of the frame body 21 and the base plate 22 as in the present embodiment, the sliding recess 24 can be formed simply by inserting the base plate 22 into the through hole 23 of the frame body 21.

If the lower plate 15 is not used, the upper plate 12 may be externally fitted to the plate-like body 11 so as to be movable up and down.

  The heat insulating sheet 16 is formed in a circular shape. The plate-like body 11 is provided on the bottom plate portion 42 of the lower plate 15 via the heat insulating sheet 16. Examples of the material of the heat insulating sheet 16 include foams such as urethane foam.

  In this way, if a plurality of protrusions 52 are provided on the lower surface 11b of the plate-like body 11, it is possible to reliably prevent the plate-like body 11 from sinking into the heat-insulating sheet 16, so that the frictional heat described later can be generated more efficiently. There is an advantage that can be made.

Next, the heat generating operation of the heat generating member 3 will be described.
As shown in FIGS. 8 and 9, when the shoe insole 1 is inserted into the shoe as shown in FIG. 3 and the shoe 4 placed on the shoe sole 5 is worn, as shown in FIGS. On the other hand, when the compressive load F is applied in the thickness direction, the rubber-like elastic body 14 causes the sliding plate 13 to slide obliquely downward on the front side along the inclination direction of the bottom surface 24a of the sliding recess 24. This causes elastic compression deformation.

As shown in FIG. 8, the sliding plate 13 also moves downward in the vertical direction while horizontally moving to the front side due to the load of the compressive load F. Therefore, the sliding plate 13 is moved forward along the inclination direction of the bottom surface 24 a of the sliding recess 24. It will slide diagonally downward. Here, if the horizontal relative displacement of the sliding plate 13 with respect to the plate-like body 11 is H, the vertical relative displacement is V, and the relative displacement in the inclination direction of the bottom surface 24a of the sliding recess 24 is S, these H, V, S The relationship
S = (H ² + V ² ) ^1/2
It is represented by

  In addition, what is necessary is just to comprise elastic bodies, such as the rubber-like elastic body 14, so that it may not be plastically deformed exceeding an elastic limit at the time of compressive deformation. Here, when the compression load F is applied, the top plate portion 32 of the upper plate 12 abuts on the plate-like body 11 and / or the inner cylinder portion 41 of the lower plate 15 before the elastic body to be compressed and deformed reaches the elastic limit. If the elastic body is configured so as not to be further compressed and deformed, there is an advantage that plastic deformation of the elastic body can be surely prevented.

  On the other hand, when the compressive load F is unloaded, the rubber-like elastic body 14 has the sliding plate 13 on the rear side along the inclination direction of the bottom surface 24a of the sliding recess 24 as shown in FIGS. Restoring to slide diagonally upward.

  The frictional heat is generated when the sliding plate 13 slides with respect to the bottom surface 24 a of the sliding recess 24 and the top plate portion 32 of the upper plate 12. Since the above-described series of operations is repeated by repeated loading and unloading of the compression load F, the temperature of the heat generating member 3 rises due to frictional heat generated continuously. As a result, the foot in contact with the shoe insole 1 is warmed, but the load and unloading of the compression load F are not related to the amount of bending of the shoe 4 during walking or stepping, and the heating member 3 is disposable. is not. Thus, the shoe insole 1 has the advantage that the heating member 3 does not need to be replaced and the foot can be warmed regardless of the amount of bending of the shoe 4.

  Further, if the heat generating member 3 is covered with the waterproof film 6, moisture such as sweat or rainwater can be prevented from entering the heat generating member 3, so that the heat generating performance of the heat generating member 3 can be prevented from being lowered and heat generated. There is an advantage that the member 3 can be kept clean. Furthermore, if the heat insulating sheet 16 is provided on the lower surface 11b side of the plate-like body 11, there is an advantage that heat can be prevented from escaping from the lower surface 11b side of the plate-like body 11. In any case, in order to prevent low-temperature burn (so-called low-temperature burn) of the foot due to long-time contact, the combination of the material of each component described above is in contact with the foot on the upper surface 3a side of the heat generating member 3. It is desirable that the temperature of the portion does not rise to 39 ° C. or more (maintains less than 39 ° C.).

  In addition, you may provide the heat insulation sheet 16 in the lower surface 3b side of the heat generating member 3, as shown in FIG.10 and FIG.11. In this case, the heat generating member 3 and the heat insulating sheet 16 may be covered with the waterproof film 6 as shown in FIG. 10, or the heat generating member 3 may be covered with the waterproof film 6 as shown in FIG. A heat insulating sheet 16 may be provided on the lower surface 3 b of the heat generating member 3.

  Further, when the heat generating member 3 is detachably fitted into the recess 8 of the insole body 2 and the water absorbing sheet 7 is provided on each of the upper surface 3a side and the lower surface 3b side of the heat generating member 3, the heat generating member 3 is reversed as shown in FIG. The heat generating member 3 can be used by being inserted into the recess 8, and sweat can be absorbed also by the water absorbing sheet 7 on the lower surface 3 b side (the upper side in the inverted state) of the heat generating member 3, so that deodorization in the shoe 4 can be achieved. There is an advantage. In this case, as shown in FIG. 13, when it is not necessary to warm the foot, the heat generating member 3 is removed from the concave portion 8, and the insole material 61 formed in accordance with the shape of the concave portion 8 is replaced with the concave portion 8 instead of the heat generating member 3. Can also be inserted.

  As shown in FIG. 12, when the compressive load F is applied in the thickness direction to the heat generating member 3 turned upside down, the rubber-like elastic body 14 has the sliding plate 13 for sliding. By sliding forward along the inclination direction of the bottom surface 24a of the recess 24, the elastic member is elastically compressed and deformed.

  The sliding plate 13 horizontally moves forward due to the load of the compression load F. At this time, the plate-like body 11 descends vertically downward. Therefore, when viewed as relative displacement with respect to the plate-like body 11, the sliding plate 13 is slid obliquely upward on the front side along the inclination direction of the bottom surface 24a of the sliding recess 24 as shown in FIG.

  On the other hand, when the compressive load F is unloaded, the rubber-like elastic body 14 is restored so that the sliding plate 13 slides rearward along the inclination direction of the bottom surface 24a of the sliding recess 24.

  Also in this case, the frictional heat is generated when the sliding plate 13 slides with respect to the bottom surface 24 a of the sliding recess 24 and the top plate portion 32 of the upper plate 12 in the heat generating member 3 in an inverted state. Since the above-described series of operations is repeated by repeated loading and unloading of the compression load F, the temperature of the heat generating member 3 rises due to frictional heat generated continuously. Accordingly, the foot in contact with the insole 1 for shoes is warmed regardless of the amount of bending of the shoe 4, but the amount of heat conducted to the foot due to the presence of the heat insulating sheet 16 provided on the lower surface 11b side of the plate-like body 11 is increased. There is an advantage that it can be reduced. The water absorbent sheet 7 provided on the lower surface 3b side of the heat generating member 3 may have heat insulation properties.

  As shown in FIGS. 14 and 15, the shoe 74 according to the second embodiment includes, for example, three (at least one) heat generating members 3 configured in the same manner as the first embodiment as main components. ing.

  As shoes 74, long boots, half-length boots, waist boots, sneakers, boots, high heels, pumps, chucker boots, athletic shoes, basketball shoes, skate boots, volleyball shoes, dance shoes, safety shoes, leather shoes, loafers, outerwear, Examples include front rubber shoes, wooden shoes, driving shoes, riding boots, motocross boots, trekking shoes, and climbing shoes. When the shoe 74 is configured for the right foot as shown in FIG. 15, the shoe 74 for the left foot may be configured symmetrically with the shoe 74 for the right foot.

  The heat generating member 3 is fitted into, for example, three (at least one) concave portions 78 provided on the upper surface 75 a of the shoe sole 75. As shown in FIG. 15, the recess 78 includes a portion of the upper surface 75 a of the shoe sole 75 that is in contact with the vicinity of the foot's main ball, a portion of the foot that is in contact with the small heel, and a portion of the foot that is in contact with the heel. There are three locations.

  Here, if only the lower surface 3 b side of the heat generating member 3 is fixed to the bottom surface 78 a of the concave portion 78 by bonding with an adhesive through the waterproof film 6, the heat generating member 3 is prevented from dropping from the concave portion 78. In addition to being prevented, there is an advantage that the heat generating member 3 can be deformed without hindrance by being not fixed to the wall surface 78c of the recess 78. Moreover, each other technique described in the first embodiment can also be applied to the present embodiment.

  Note that the number and setting positions of the heat generating members 3 can be changed as appropriate, and one or more heat generating members 3 can be provided at appropriate positions on the shoe sole 75. The recessed part 78 should just be provided according to the shape of the heat generating member 3 to be used, a number, and a set position.
