Description

  The present invention relates to a boot shape holder for holding a boot in a certain shape.

  When the long boot or the like is removed and placed at the entrance or the like, the barrel portion of the boot is easily bent. If left in such a state for a long time, there is a possibility that wrinkles will occur at the bent portion in the barrel portion and that the shape may be lost. For this reason, when the boot is not used for a long time, it is necessary to store it so that the barrel portion is not bent.

  Conventionally, a boot keeper has been proposed in order to prevent such bending of the boot barrel (see, for example, Patent Document 1). This boot keeper is inserted into the trunk cylinder portion of the boot to maintain the shape of the trunk cylinder portion, and has a heel stretching member for pushing and stretching the heel attached to the vicinity of the ankle joint of the trunk cylinder portion. Yes. Further, in the disclosed technique in Patent Document 2, a shape holder constituted by a transparent plastic bag body having an outer shape capable of bulging in a trunk cylinder portion of a boot by injecting air from a compressed air injection / discharge valve. Has also been proposed. In the disclosed technique of Patent Document 2, since the bag body can be bulged by filling with compressed air, the boot does not break and does not fall on its own by inserting it into the boot barrel. Therefore, it can greatly contribute to the shape maintenance.

  By the way, the bottom part in the boot from the heel where the foot is inserted to the toe absorbs sweat from the sole. If you keep walking while wearing such boots, friction will be applied, the temperature inside the boots will rise, and it will cause an environment that is easy to breed by germs due to sweat. In order to prevent such germs from propagating, moisture at the inner bottom must be released.

  However, the boot keeper disclosed in Patent Document 1 is configured as a column shape in which a cloth bag longer than the trunk portion is enclosed. When the boot keeper having such a configuration is fitted into the trunk cylinder portion of the boot, the above-described inner bottom portion is sealed from the outside air. Since the technology disclosed in Patent Document 2 is also configured to swell the bag body in the boot barrel, the boot inner bottom is similarly sealed from the outside air.

As a result, moisture at the bottom of the boot could not be released, causing germs to propagate and causing odors.
JP 2005-6915 A Japanese Patent Application Laid-Open No. 2002-223813

  Therefore, the present invention has been devised in view of the above-described problems, and the object of the present invention is to hold the boot in a certain shape and to allow the inside of the boot and the outside air to be opened in the meantime. Thus, an object of the present invention is to provide a boot-shaped holding body capable of removing malodor from the inner bottom.

  The boot-shaped holding body according to claim 1 of the present invention is a boot-shaped holding body that holds the shape of the trunk cylinder portion by being inserted into the trunk cylinder portion of the boot. And a groove formed in the lower end of the side wall of the main body, and the main body is shaped by the enclosed gas. It is characterized by presenting.

  A boot-shaped holding body according to claim 2 of the present invention is a boot-shaped holding body that holds the shape of the trunk cylinder portion by being fitted into the trunk cylinder portion of the boot. It has a through-hole provided in the side wall surface lower part of the main-body part, or a groove part formed in the side wall lower end of the above-mentioned main-body part, and the above-mentioned main-body part exhibits regularity.

  The boot-shaped holding body according to claim 3 of the present invention is characterized in that, in the invention according to claim 1 or 2, at least one through small hole is further formed on a side surface of the main body.

  In the present invention having the above-described configuration, since the formability is exhibited, the trunk portion does not break and does not fall down on its own, so that the shape can be held in an upright state. Moreover, it is possible to remove malodor from the inner bottom by making it open to the boot inner bottom and the outside air due to the presence of the groove and the through hole.

  Hereinafter, as a best mode for carrying out the present invention, a boot shape holding body for holding a boot in a certain shape will be described in detail with reference to the drawings.

First embodiment

  FIG. 1: has shown the perspective view of the boot shape holding body 1 as 1st Embodiment to which this invention is applied. This boot-shaped holding body 1 is mainly configured by rounding and connecting plastic sheets 10 into a cylindrical shape.

  The plastic sheet 10 is a thermoplastic resin sheet such as polyethylene having no air permeability. Incidentally, this thermoplastic resin may be appropriately selected from polypropylene, polyethylene terephthalate, nylon, vinyl chloride, polycarbonate and the like in addition to polyethylene.

  As shown in FIG. 2, the plastic sheet 10 has strip-shaped air chambers 11 elongated in the vertical direction y, in which gas is previously sealed, arranged in a row in the width direction x. The air chamber 11 is configured by forming the plastic sheet 10 by two rectangular sheets and superimposing them on each other and performing thermocompression bonding in the vertical direction, but is not limited thereto. It may be embodied by any other known method. In the example of FIG. 2, the air chamber 11 is formed on the surface 10 b of the plastic sheet 10. That is, the air chamber 11 is configured to protrude in a convex shape on the surface when viewed from the cross section.

  After producing such a plastic sheet 10, it is rolled 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 in the width direction x so as to be located on the inner wall side. And the edge part of this width direction x is connected mutually, and it is comprised by the cylinder shape and the through-hole 13 penetrated to an up-down direction is formed.

  At this time, the air chamber 11 is not formed on the back surface 10 a of the plastic sheet 10, and is configured with a smooth surface. For this reason, when the plastic sheet 10 is rolled, it is possible to easily form a cylindrical shape so that the back surface 10a is on the outside and the front surface 10b on which the air chamber 11 is provided is on the inside.

  When the boot-shaped holding body 1 configured in this tubular shape is actually used, for example, as shown in FIG. As a result, the air chambers 11 constituting the boot-shaped holding body 1 are pressed against each other between the adjacent air chambers 11 as shown in the horizontal sectional view shown in FIG. Due to the compression between the air chambers 11, an expansion force f that acts to push the air chambers 11 toward the outside acts. The outer side of the boot-shaped holding body 1 is circumscribed with the inner wall surface of the inserted barrel portion 21, but an expansion force f based on the compression between the air chambers 11 is loaded on the barrel portion 21. . As a result, the barrel cylinder portion 21 is always subjected to a force to expand the diameter outward, so the barrel cylinder portion 21 in the boot 2 does not break and does not fall down on its own. It will be possible to contribute greatly. In particular, in the present invention, it is possible to insert the boot-shaped holding body 1 without protruding from the barrel portion 21, and in particular, when displaying as a display item, a self-supporting image is presented to the consumer. It is also possible to give.

  Note that the volume, size, position, interval, number of arrangements, shape, and the like of the air chambers 11 are adjusted in advance so that a desired expansion force f acts by the compression between the air chambers 11. It is desirable that the dimensions such as the size and the volume of each air chamber 11 are adjusted to be uniform in order to exert a stable expansion force f. Moreover, the air chamber 11 may be comprised as a space mutually independent, and may be comprised as a mutually continuous space. When the air chambers 11 are made continuous with each other, a bypass or the like for connecting the air chambers 11 to each other may be provided.

  Incidentally, as shown in FIG. 3 (b), the barrel portion 21 of the boot 2 may have a streamlined shape. When the boot-shaped holding body 1 is inserted into the barrel portion 21 having such a shape, the gas in the air chamber 11 is swollen from the dent portion in the barrel portion 21 as shown in FIG. Will be dispersed. In particular, since the air chamber 11 is configured to have a strip shape in the vertical direction, the gas sealed in the air chamber 11 easily moves in the vertical direction and can be dispersed. By providing such an air chamber 11, gas can be dispersed along the streamlined shape of the barrel portion 21 to exert an expansion force. As a result, since an extra expansion force is not locally applied to the leather that constitutes the barrel portion 21, it is possible to realize shape retention that is easy for the leather that constitutes the barrel portion 21. Become.

  Incidentally, the boot-shaped holding body 1 is formed in a cylindrical shape by rounding in the width direction x, so that a through hole 13 is formed. For this reason, as shown in FIG. 3, the inner bottom portion 23 as a space including the inner bottom in the boot 2 is opened to the outside air through the through hole 13. At this time, when the boot-shaped holding body 1 is inserted into the barrel portion 21, it is desirable to raise it to a height that does not reach the heel portion 24. Thereby, it becomes possible to improve the openness of the inner bottom portion 23 to the outside air.

  Thereby, it becomes possible to release moisture at the inner bottom 23 of the boot 2, to prevent the propagation of various germs, and to suppress malodors.

  In the above-described embodiment, the air chamber 11 is described as an example in which the air chamber 11 is configured on the surface 10b of the plastic sheet 10. By bending the surface 10b of the air chamber 11 into a cylindrical shape so as to form an inner wall, it becomes possible to improve the degree of compression between the air chambers 11 protruding inward, thereby exerting the expansion force f. Is possible.

  However, the air chamber 11 may not be formed on the surface 10b of the plastic sheet 10. For example, the air chambers 11 may be simply configured in a continuous manner regardless of whether or not they are formed on the surface 10b.

Second embodiment

  FIG. 5 (a) shows a perspective view of a boot-shaped holding body 3 as a second embodiment to which the present invention is applied. The boot-shaped holding body 3 includes a main body 30 in which a plastic sheet into which gas has been previously sealed is cylindrical, and at least one protrusion 32 that protrudes further downward from the lower end of the main body 30. ing. A through hole 31 is provided in the cylindrical main body 30. Moreover, in the following description, although the case where the protrusion part 32 is formed over two is demonstrated to an example, it is not limited to this, It is made to comprise by what number, volume, and shape. Also good.

  This plastic sheet is a thermoplastic resin sheet such as polyethylene having no air permeability. Incidentally, this thermoplastic resin may be appropriately selected from polypropylene, polyethylene terephthalate, nylon, vinyl chloride, polycarbonate and the like in addition to polyethylene.

  The main body 30 can maintain a fixed shape by being sealed with air. The projecting portion 32 is configured so that gas is enclosed in advance and at least gas can be sent and received between the main body portion 30 and the projecting portion 32. That is, the internal space of the protrusion 32 and the internal space of the main body 30 are connected to each other.

  The protrusion 32 is elastically contractible up and down. Since the internal space of the protrusion 32 and the main body 30 are connected to each other, when the protrusion 32 is pressed from the bottom, the protrusion 32 itself is elastically contracted as shown in FIG. As a result, the height of the boot shape holder 3 can be reduced. In the meantime, the gas in the protrusion part 32 is sent into the main-body part 30. FIG. By adjusting the amount of gas sealed in the main body 30 and the protrusion 32, the protrusion 32 is pushed and contracted, and the expansion force f is generated by the gas fed into the main body 30. You may make it act.

  In particular, in the present invention, by providing the protruding portion 32 having a volume smaller than that of the main body portion 30, the protruding portion 32 can be easily stretchable.

  In addition, the main-body part 30 and the protrusion part 32 may be comprised from the elastic material which has regularity, such as urethane. By constructing the projecting portion 32 with a smaller cross-sectional area than the main body portion 30, it can be easily elastically contracted when pressed.

  When the boot-shaped holding body 3 configured in this tubular shape is actually used, for example, as shown in FIG. Since the main body portion 30 is sealed with air and has a fixed shape, the body tube portion 21 is not folded and does not fall on its own, so that its shape is held upright. It becomes possible to do. If the boot 2 has a short barrel portion 21 such as a half boot as shown in FIG. 6 (b), the boot-shaped holding body 3 is inserted into the barrel portion 21 and is then inserted. The protrusion 32 is contracted by pressing from above. Thereby, it becomes possible to push down the height of the boot shape holding body 3, and it becomes possible to match | combine with the length of the trunk | drum cylinder part 21. FIG.

  For this reason, when the boot 2 is displayed as an exhibit, the boot shape holder 3 is made invisible from the view of the consumer, so that it is possible to give a self-supporting image. Further, even if the boot 2 is a long boot with a long barrel portion 21 or a short boot with a short barrel portion 21, that is, the length of the barrel portion of the boot is configured to any length. However, by adjusting the height with the boot-shaped holding body 3 that is configured so that the protruding portion 32 can be extended and contracted, it is possible to configure the protrusion 32 so that it is not visible from the consumer's field of view.

  By the way, this boot-shaped holding body 3 is formed in a cylindrical shape so that a through hole 31 is formed. For this reason, as shown in FIG. 6, the inner bottom 23 as a space including the inner bottom of the boot 2 is opened to the outside air through the through hole 13. Thereby, it becomes possible to release moisture at the inner bottom 23 of the boot 2, to prevent the propagation of various germs, and to suppress malodors.

  FIGS. 7A and 7B show a boot-shaped holding body 7 incorporating the technical ideas of both the first embodiment and the second embodiment.

  The boot-shaped holding body 7 has a plurality of rows of strip-shaped air chambers 11 that are elongated in the vertical direction y, in which gas is previously sealed, in the width direction x. The air chamber 11 is configured by forming the plastic sheet 10 by two rectangular sheets, and superimposing these sheets on each other and performing thermocompression bonding in the vertical direction. Further, some of the air chambers 11 are extended by a length corresponding to the protruding portion 32. Further, these air chambers 11 are continuous with each other via a bypass (not shown), and are capable of sending air over at least one air inlet.

  By forming the plastic sheet 10 having such a planar shape into a cylindrical shape by rounding in the width direction x, a boot-shaped holding body 7 having a form as shown in FIG. 7B can be obtained.

  In this boot-shaped holding body 7, it is possible to apply an outward expansion force by pressing the adjacent air chamber 11. Further, since the protrusion 32 is provided at the same time, the height can be adjusted by making it elastically contractible. Further, the projecting portion 32 may be pushed and contracted, and the expansion force f may be applied by the gas fed into the main body portion 30.

Third embodiment

  FIGS. 8A and 8B are perspective views of a boot-shaped holding body 4 as a third embodiment to which the present invention is applied. This boot-shaped holding body 4 is formed in a main body portion 40 in which a plastic sheet into which a gas has been previously sealed is formed in a cylindrical shape, a through hole 42a provided in a lower portion of the side wall surface of the main body portion 40, or a lower end of the side wall of the main body portion Grooved portion 42b. Incidentally, the groove 42a and the through hole 42b may be formed in any shape, and may be formed in any number. The through hole 42 a is connected to the through hole 41 in the cylindrical main body 40. The location where the through hole 42a is provided is adjusted in advance in relation to at least the position of the inner bottom 23 in the boot 2, but is preferably formed at least in any position of the lower half. The main body 40 can maintain a fixed shape by being sealed with air.

  When the boot-shaped holding body 3 configured in this cylindrical shape is actually used, for example, as shown in FIGS. 9A and 9B, the boot-shaped holding body 3 is inserted into the trunk cylinder portion 21 of the boot 2. Since the main body portion 40 is sealed with air and has a fixed formability, the trunk portion 21 does not break and does not fall down on its own, which greatly contributes to the shape maintenance. It becomes possible.

  9A, the inner bottom 23 as a space including the inner bottom in the boot 2 is opened to the outside air through the groove 42a and the through hole 41. FIG. Thereby, it becomes possible to release moisture at the inner bottom 23 of the boot 2, to prevent the propagation of various germs, and to suppress malodors. In addition, as a shape of this groove part 42a, it is desirable to be comprised from the viewpoint of manufacturability at the rectangular shape or the shape which rounded the corner | angular of the said rectangle.

  In FIG. 9B, the inner bottom 23 as a space including the inner bottom in the boot 2 is opened to the outside air through the through hole 42 b and the through hole 41. Thereby, it becomes possible to release moisture at the inner bottom 23 of the boot 2, to prevent the propagation of various germs, and to suppress malodors.

  Of course, by configuring at least two groove portions 42a, the same function as that of the protruding portion 32 in the second embodiment may be exhibited.

  Furthermore, in the present embodiment, at least one through small hole may be further formed on the side surface of the main body 40. The side surface of the main body portion 40 here faces the inner wall of the barrel portion 21. By forming a large number of small through holes on the side surface, the air permeability and ventilation of the barrel portion 21 are improved. It becomes possible to make it.

  In the third embodiment, the main body 30 may of course be made of an elastic material having a regularity such as urethane instead of a plastic sheet.
