Description

Boot shape holder {BOOT SHAPE MAINTAINING BODY}

The present invention relates to a boot shape retainer for maintaining the boots in a constant shape.

Take off the long boots and put them on the porch, the body of the boots easily bent. If left in such a state for a long time, wrinkles may occur at the bent portion on the trunk, and furthermore, shape collapse may occur. For this reason, when a boot is not used for a long time, it is necessary to store it so that a torso may not be bent.

Conventionally, in order to prevent the bending in the trunk | drum of such a boot, a boot keeper is proposed (for example, refer patent document 1). The boot keeper is inserted into the torso of the boot to maintain the shape of the torso. The boot keeper has a wrinkle-unfolding member for pushing out wrinkles formed near the ankle joint of the torso. In addition, in the technique disclosed in Patent Literature 2, a shape retainer constituted by a transparent plastic bag having an external shape that can be expanded in a trunk portion of a boot by injecting air from a compressed air injection / exhaust valve is also proposed. . In the disclosed technique of Patent Document 2, since the bag can be expanded by filling with compressed air, by inserting this into the boot body, the boot is not bent and it does not stand on its own. Can contribute.

By the way, the boot inner bottom part from the heel to which a foot is inserted to a tiptoe absorbs the sweat from a sole. If you keep wearing these boots, friction is applied to them, which increases the temperature in the boots, and causes a variety of sweat bacteria to create an environment that is easy to breed. In order not to propagate these germs, the moisture of the inner bottom must be released.

However, the boot keeper of the technique disclosed in Patent Document 1 is configured to have a pillar shape in which a bag longer than the trunk portion is sealed. When the boot keeper having such a configuration is inserted into the body of the boot, the inner bottom is sealed from the outside air. Since the opening technique of patent document 2 also has a structure which expands a bag body in a boot trunk part, the boot inner bottom part is similarly sealed from the outside air.

As a result, moisture in the boot inner bottom could not be released, and it was a cause of propagation of various germs, which also caused a bad smell.

EMBODIMENT OF THE INVENTION Hereinafter, as a best form for implementing this invention, the boot shape holder for holding a boot in a fixed shape is demonstrated in detail, referring drawings.

1st Embodiment

1 is a perspective view of a boot-shaped holder 1 as a first embodiment to which the present invention is applied. This boot-shaped holder 1 is mainly comprised by connecting the plastic sheet 10 roundly in a cylindrical shape.

The plastic sheet 10 is a thermoplastic resin sheet such as polyethylene having no air permeability. In addition, as this thermoplastic resin, you may select suitably from polypropylene, polyethylene terephthalate, nylon, vinyl chloride, polycarbonate, etc. other than polyethylene.

As shown in FIG. 2, this plastic sheet 10 arrange | positions the air chamber 11 of strip shape long and thin in the up-down direction y in which gas is previously sealed in the form of a line in the width direction x. The air chamber 11 is constituted by forming the plastic sheet 10 by two rectangular sheets, and superimposing them on each other and performing thermal compression in the vertical direction. You may actualize this by a method. In addition, in this example of FIG. 2, the air chamber 11 is formed in the surface 10b of the plastic sheet 10. As shown in FIG. That is, the air chamber 11 is comprised so that it may protrude in convex shape on the surface when it sees in cross section.

After producing such a plastic sheet 10, it is rounded in the width direction x. At this time, as shown in FIG. 1, the surface 10b of the plastic sheet 10 in which the air chamber 11 is formed is rounded together in the width direction x so that it may be located in the inner wall side. And the edge part of the width direction x is mutually connected, and is comprised in the cylindrical shape, and the through-hole 13 penetrating in an up-down direction is formed.

At this time, the air chamber 11 is not formed in the back surface 10a of the plastic sheet 10, and is comprised by the smooth surface. For this reason, when the plastic sheet 10 is rounded, this back surface 10a can be made into the outer side, and the surface 10b in which the air chamber 11 was provided can become inside, and it can be comprised easily in a cylindrical shape. .

When actually using the boot-shaped holder 1 constituted by the tubular shape, for example, as shown in FIG. 3, the boot-shaped holder 1 is inserted into the trunk portion 21 of the boot 2. As a result, the air chambers 11 constituting the boot-shaped holder 1 are pressed against each other with the adjacent air chambers 11, as shown in the horizontal sectional view shown in FIG. By the press of these air chambers 11, the expansion force f which tries to push the air chamber 11 toward an outer side acts. The outer side of the boot-shaped holder 1 is circumscribed with the inner wall surface of the inserted trunk portion 21, and an expansion force f based on the pressure between the air chambers 11 is applied to the trunk portion 21. . As a result, since the force which always tries to expand the diameter to the trunk | drum 21 always acts, the trunk | drum 21 in the boots 2 does not bend and does not stand on its own, and it is large in maintaining the shape. It is possible to contribute. In particular, in the present invention, it is possible to insert the boot-shaped holder 1 without protruding from the trunk portion 21, and in particular, it is also possible to give the consumer an image that is naturally self-supporting when displaying as a display. Done.

Moreover, the volume, size, position, space | interval, arrangement | positioning number, shape, etc. of the air chamber 11 are previously adjusted so that the desired expansion force f may act by the press of the air chambers 11 comrades. In order to exert stable expansion force f in all the air chambers 11, it is preferable that each dimension, such as these sizes and a volume, is adjusted so that it may become uniform. In addition, the air chamber 11 may be comprised as mutually independent space, and may be comprised as mutually continuous space. In the case where the air chambers 11 are continuously connected to each other, a bypass or the like for connecting the air chambers 11 to each other may be provided.

In addition, as shown in FIG.3 (b), the trunk | drum 21 of the boots 2 may be a streamlined shape. When the boot-shaped holder 1 is inserted into the trunk portion 21 having such a shape, as shown in FIG. 3 (b), the gas in the air chamber 11 has a dent in the trunk portion 21. It is dispersed from the part to the part with bulging. In particular, since this air chamber 11 is comprised so that it may become strip shape in the up-down direction, the gas enclosed in the air chamber 11 will move easily in a vertical direction, and will be dispersible. By providing such an air chamber 11, the gas can be dispersed along the streamline of the trunk portion 21 to exert an expansion force. As a result, unnecessary expansion force is not applied locally to the leather constituting the trunk portion 21, so that it is possible to realize a soft shape retention even for the leather constituting the trunk portion 21.

Incidentally, the boot-shaped holder 1 is rounded in the width direction x to form a cylindrical shape, whereby a through hole 13 is formed. For this reason, as shown in FIG. 3, the inner bottom part 23 as a space containing the inner bottom in the boot 2 is opened to the outside air through this through hole 13. As shown in FIG. At this time, when inserting the boot-shaped holder 1 into the trunk portion 21, it is preferable to raise it to a height not reaching the heel portion 24. Thereby, it becomes possible to improve the opening property to the outside air of the inner bottom part 23. As shown in FIG.

This makes it possible to release moisture from the inner bottom portion 23 of the boot 2, to prevent propagation of various germs, and to suppress odors.

In addition, in the above embodiment, the air chamber 11 is demonstrated to the last as an example which comprises the air chamber 11 in the surface 10b of the plastic sheet 10. As shown in FIG. By bending the tubular shape so that the surface 10b of this air chamber 11 forms an inner wall, it becomes possible to improve the degree of the press between the air chambers 11 which protrude inward, and thereby the expansion force f It becomes possible to exert.

However, the air chamber 11 may not be constituted from the surface 10b of the plastic sheet 10. For example, regardless of whether or not it is formed on the surface 10b, only the air chamber 11 may be simply formed in a continuous bead shape.

2nd Embodiment

FIG.5 (a) has shown the perspective view of the boot-shaped holder 3 as 2nd Embodiment to which this invention was applied. The boot-shaped holder 3 has a main body portion 30 having a cylindrical plastic sheet in which gas is sealed in advance, and at least one protruding portion 32 protruding further downward from the lower end of the main body portion 30. Equipped with. The through-hole 31 is provided in the main-body part 30 comprised in this cylindrical shape. In addition, in the following description, although the case where the protrusion part 32 is formed over two is demonstrated as an example, it is not limited to this, You may comprise in any number, volume, and shape.

This plastic sheet is a thermoplastic resin sheet such as polyethylene having no air permeability. In addition, as this thermoplastic resin, you may select suitably from polypropylene, polyethylene terephthalate, nylon, vinyl chloride, polycarbonate, etc. other than polyethylene.

As the main body 30 is sealed with air, it is possible to maintain the shaping. Moreover, the protrusion part 32 is made to be filled with gas previously, and it is the structure which can supply and discharge gas between the main body part 30 and the protrusion part 32 at least. That is, the inner space of the protrusion part 32 and the inner space of the main body part 30 are in a state of being connected to each other.

The protrusion part 32 is free to elastically contract up and down. Since the protrusion part 32 and the main body part 30 are connected to each other, when the protrusion part 32 is pressed from the bottom, as shown in FIG. 5 (b), the protrusion part 32 itself contracts elastically. As a result, the height of the boot-shaped holder 3 can be made low. In the meantime, the gas in the protrusion part 32 is supplied to the main-body part 30. FIG. In addition, by adjusting the amount of the gas enclosed in the main body 30 and the protruding portion 32, the protruding portion 32 is pushed in and contracted, and the expansion force f is caused by the gas fed into the main body 30. ) May be applied.

In particular, in the present invention, the protrusion 32 having a smaller volume than that of the main body 30 can be provided so that the protrusion 32 can be freely stretched.

In addition, the main body part 30 and the protrusion part 32 may be comprised from the elastic material which has the shaping | molding property, such as urethane. By constructing the projecting portion 32 in a cross-sectional area smaller than that of the main body portion 30, it is possible to elastically contract easily when pressed.

When actually using the boot-shaped holder 3 constituted by the tubular shape, for example, as shown in FIG. 6 (a), the boot-shaped holder 3 is inserted into the trunk portion 21 of the boot 2. Since the main body portion 30 is sealed with air and maintains a good shape, the trunk portion 21 is not bent and does not stand on its own, and thus the shape can be maintained in an upright state. For example, as shown in FIG. 6 (b), when the body portion 21 such as the half boots is short, the boot shape holder 3 is inserted into the body portion 21, and By pressing this from top to bottom, the protrusion 32 is retracted. As a result, the height of the boot-shaped holder 3 can be pushed down, and the length of the trunk portion 21 can be adjusted.

For this reason, when displaying the boot 2 as an exhibit, it becomes possible to give an image which is naturally self-supporting by making this boot-shaped holding body 3 invisible from the consumer's field of view. Further, even if the boots 2 are long boots with a long body portion 21 or a half boots with a short body portion 21, that is, even if the length of the body portion of the boots is configured to any length, the extension of the protrusions 32 The height adjustment is performed by the freely configured boot-shaped holder 3 so that the configuration can be made invisible from the consumer's field of view.

Incidentally, the boot-shaped holder 3 is formed in a tubular shape, whereby a through hole 31 is formed. For this reason, as shown in FIG. 6, the inner bottom part 23 as a space containing the inner bottom in the boot 2 is opened to the outside air through this through hole 13. As shown in FIG. This makes it possible to release moisture from the inner bottom portion 23 of the boot 2, to prevent propagation of various germs, and to suppress odors.

FIG.7 (a), (b) has shown the boot-shaped holder 7 which receives the technical idea of both 1st Embodiment and 2nd Embodiment.

The boot-shaped holding body 7 arrange | positions the elongate strip-shaped air chamber 11 in the width direction x over several rows in the up-down direction y which gas is enclosed previously. The air chamber 11 is constituted by forming the plastic sheet 10 by two rectangular sheets, stacking them together and performing thermocompression bonding in the vertical direction. Moreover, about some air chamber 11, it extends by the quantity of length corresponding to the protrusion part 32. As shown in FIG. Moreover, each of these air chambers 11 is continuous through the bypass which is not shown in figure, and it is possible to supply air through the at least one air inlet port.

By forming the plastic sheet 10 having such a planar shape in a cylindrical shape by rounding it in the width direction x, it is possible to obtain a boot-shaped holder 7 having a form as shown in Fig. 7B. do.

In this boot-shaped holding body 7, it becomes possible to apply the expansion force to the outside by the press of the adjacent air chamber 11. Moreover, since the protrusion part 32 is provided at the same time, height adjustment is also possible by making it elastically shrink free. In addition, the protruding portion 32 may be pushed in and contracted, and the expansion force f may be applied by the gas fed into the main body portion 30.
