Description

[Detailed Description of the Invention] The present invention comprises a heating element which is used to compensate for a drop in human body temperature by the heat dissipation energy of the heating element in conditions of low environmental temperature such as in winter or in cold regions. The present invention relates to a cartridge, footwear for using the same, and heat-retaining footwear using the cartridge.

I. The temperature of the human body may drop during the winter or in cold regions where the environmental temperature is low, or when you are sick.

For this reason, measures are usually taken to warm the body voluntarily or forcibly to compensate for the drop in body temperature and keep the body warm. The present invention attempts to accomplish this by using a so-called disposable body warmer (hereinafter referred to as a heating element) that uses the heat of oxidation reaction of iron powder to keep warm, which has been particularly widely used recently.

Its features include a technical concept in which a cartridge that holds a heating element is configured to generate heat at an optimal temperature for a long period of time, and a technical concept in which it is configured to stimulate the heating element to promote heat generation. , a technical idea that is configured to prevent the movement of the heating element, and a technical idea that is configured to incorporate a cartridge configured in this way into footwear to keep the feet warm without causing discomfort. The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

1 to 5 show a first embodiment of the present invention.

The cartridge 1 in this embodiment is shown in FIGS. 1 and 2.
As shown in the figure, it consists of upper and lower sheet-like members 2 and 3 that face each other, and the lower sheet-like member 3 is cut off at the rear so that it is shorter than the upper sheet-like member 2. A large number of vent holes 4 are provided in at least one side of the upper and lower sheet members 2 and 3 (the drawing shows vent holes 4 in both sheet members 2 and 3). ). Further, on the mutually opposing surfaces 2a and 3a of the sheet-like members 2 and 3,
A mushroom-shaped fitting protrusion 5 is provided and constitutes a hook-and-loop fastener T. As shown in FIG. 6, the hook-and-loop fastener T is constructed by providing a mating protrusion 5 on the opposing surface 2a of the upper sheet-like member 2 and a raised fabric 6 on the opposing surface 3a of the lower sheet-like member 3. You can do it like this. The upper and lower sheet-like members 2 and 3 are partially attached to each other by means such as stitching so that they can be easily opened and closed using the hook-and-loop fastener T. FIG. 3 shows a case where a heating element (disposable body warmer) 8 is incorporated into the cartridge 1 constructed as described above.

In this state, the heating element 8 is held between the upper and lower sheet-like members 2 and 3, and the fitting protrusion 5 forming the hook-and-loop fastener T
This prevents its movement. Furthermore, since an air layer is formed between the upper and lower sheet-like members 2 and 3 and the heating element 8, ventilation into the interior of the heating element 8 is improved, and sufficient heat generation action of the heating element 8 can be obtained. . In other words, the heat generation effect can be accelerated. Note that the above-mentioned ventilation is normally performed through the nonwoven fabric since the exterior of the heating element 8 is made of nonwoven fabric. The cartridge 1 having the above structure shown in this first embodiment is used by being attached to a slipper 9 having the structure shown in FIG. 4, for example.

The slipper 9 in this case has a bulge 10 formed at the inner heel of the main body 9a, and a raised fabric 12 as a surface bonding member is formed on the surface of the bulge 10. Swelling part 10
The remaining inner bottom plane part 11 excluding the inner bottom plane part 11 serves as a storage part for the cartridge 1. As shown in FIG.
The fitting protrusion 5 on the surface 2a on the rear side of the upper sheet-like member 2 is surface-adhered to and fixed to the raised fabric 12 of the bulge 10, thereby forming heat-retaining footwear A.

In this state, the upper surface of the upper sheet-like member 2 is made flat. That is, the bulge 1
The height of 0 is defined by the thickness of the heating element 8 in use, the thickness of the upper and lower sheet members 2 and 3, and the height formed between the heating element 8 and the upper and lower sheet members 2 and 3. In consideration of the air layer factor, the upper surface of the upper sheet-like member 2 is set to be flat when stored. With the heat-retaining footwear A configured as described above, the weight of the user on the foot and the movement of the weight are transmitted to the heating element 8 via the fitting protrusion 5 and stimulate it, so that the heating element 8 is heated. The exothermic effect will be promoted.

Further, the upper and lower sheet-like members 2 and 3 are provided with a large number of ventilation holes 4, which are formed between the upper and lower sheet-like members 2 and 3 and the heating element 8. Fresh air can be supplied to the heating element 8 via the air layer, and the reaction atmosphere after the oxidation reaction can be exhausted. This is actually done by the above-mentioned stimulation by the locking projection 5. That is, since the insert protrusion 5 compresses the air layer in the area where the weight is applied, the reaction atmosphere is discharged from the vent hole 4. In addition, at a portion where the weight is moved and the compressed air layer returns to its original state due to the restoring force of the insert protrusion 5 itself, fresh air is sucked into the air layer. For this reason, the heating element 8 is supplied with a large amount of fresh air into its interior, and moreover, due to the stimulating effect of the insert protrusion 5, the fresh air supplied is uniformly distributed throughout the interior of the heating element 8. , the oxidation reaction becomes active and the exothermic temperature rises. In this case, by changing the size and distribution of the vent holes 4, the amount of air passing through the vent holes 4 (the amount of fresh air and the circulating amount of the reaction atmosphere after the oxidation reaction) is limited, so the above-mentioned It is possible to control the exothermic temperature to an appropriate temperature that the body feels. Therefore, it is possible to prevent the dissipation of excess heat, to make the heat generating element 8 generate heat efficiently, and to maintain the heat generation time for a long time. still,
In this embodiment, the fitting protrusion 5 has been described as having a mushroom shape, but it is not limited to this, and other shapes such as a hook shape or a needle shape can be considered. If it is needle-shaped, the needle-shaped fitting protrusion pierces the exterior of the heat generating element 8 to actively ventilate the heat generating element 8, thereby making it possible to further improve the heat generation performance. Furthermore, it is needless to say that the footwear is not limited to slippers 9, and can be applied to all types of footwear. Next, Figures 7 to 9
A second embodiment of the present invention will be described with reference to the drawings.

In this embodiment, the lengths of the upper and lower sheet-like members 2 and 3 are approximately the same, and a bulge 1 corresponding to the bulge 10 in the first embodiment is provided on the rear upper surface of the lower sheet-like member 3.
3, and furthermore, a fitting protrusion 14 as a surface coupling member is provided on the rear lower surface of the lower sheet-like member 3.
5. Other cartridges 1
The configuration of 5 is the same as that of the first embodiment. This well-structured cartridge 15 is used by being attached to slippers 16 as footwear shown in FIG. 8, for example, by providing a raised fabric IT on the rear upper surface of the inner sole. For attachment, it is sufficient to attach the fitting protrusion 14 provided on the rear lower surface of the lower sheet-like member 3 to the raised fabric IT of the slipper 16. This results in
Heat-retaining footwear B can be constructed (see FIG. 9).
The functions and effects of the heat-retaining footwear B are the same as those of the first embodiment, so a description thereof will be omitted here. In short, in this second embodiment, the cartridge 15 is added to the existing slipper 16.
The heat-retaining footwear B can be constructed by simply providing a means for fixing the heat-retaining footwear B, which is excellent in versatility.

Furthermore, in the case of closed footwear that wraps around the instep of the foot, such as boots or short boots, the movement of the cartridge 15 is restricted to some extent by members forming the side surfaces of the footwear itself. 15 can be used without special provision of means for fixing it. Furthermore, the cartridge 15 holding the heating element 8 can be used alone other than for footwear. For example, if it is placed on a seat where the body's weight is applied, the cartridge 15 can be used in a similar manner to the first embodiment. A similar effect can be obtained. FIG. 10 is a longitudinal sectional view showing another example of the structure of the cartridge.

In this case, the cartridge 18 includes upper and lower sheet-like members 2
and 3 are set to a length sufficient to hold the heating element 8, respectively, and the upper and lower sheet-like members 2 and 3 are provided with ventilation holes 4 and fitting protrusions 5 in the same manner as in each of the above embodiments. ing. Similar to the cartridge 15 of the second embodiment, the cartridge 18 is used for closed footwear that wraps around the top of the foot, and is placed under the waist of a person while lying on their back. and used. The heat generation action and its effects are the same as in each of the above embodiments. In addition to the above-described aspects, the present invention provides a large number of ventilation holes distributed at least in the upper sheet-like member of the upper and lower sheet-like members facing each other, and A large number of p-fitting protrusions are provided on the opposing surfaces of the lower sheet, and a large number of plucking protrusions or raised fabrics are provided on the opposing surface of the lower sheet side to form a surface joint member, and a heating element is placed between the upper and lower sheet-like members. Since the cartridge is constructed in which an air layer formed by the fitting projection is provided between the heating element and the upper sheet-like member, the movement of the heating element can be prevented by the fitting projection, It is also possible to stimulate the heating element to promote the exothermic action. Furthermore,
By appropriately changing the size and distribution of the ventilation holes, it is possible to control the amount of ventilation to the heating element, and to easily set the heat generation temperature of the heating element to around the optimum temperature. Therefore, the heating element can be used efficiently and has excellent durability. Furthermore, when the above cartridge is incorporated into footwear and used, the heat generation effect can be promoted using the body weight and the movement of body weight, and stimulation can be applied separately by taking out the heating element and massaging it with your hands. There is no need to give anything.

In short, the heat-retaining footwear of the present invention has excellent heat-retaining effects and durability, and is convenient because it does not require any operation.
