Description

[Technical Field]

[0001] This invention relates to sandal-type shoes for medical care. [Background technology]

[0002] Traditionally, medical and nursing care workers often wear regular sports shoes. However, regular shoes with laces are inconvenient because the laces can come undone or get dirty, and are not necessarily suitable for use in medical and nursing care settings. For this reason, many workers currently wear Crocs rubber sandals, which do not require lacing and can be easily put on by simply slipping your feet in (see, for example, Non-Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Non-Patent Document 1] Crocs website (URL https: / / www.crocs.co.jp / ) Summary of the Invention [Problem to be solved by the invention]

[0004] However, while the conventional sandal-type shoes described above are highly convenient in terms of ease of wearing, they have drawbacks such as being prone to slipping off, making them unsuitable for use in emergencies. Therefore, there is a demand for shoes that offer a fit as close as possible to that of regular sports shoes. However, these types of shoes are not designed to allow the dimensions of each part to be adjusted to fit the user's foot shape, etc. Therefore, an improved fit cannot be expected.

[0005] The present invention was made in consideration of the above-mentioned problems, and its purpose is to provide medical care shoes that have a fit similar to that of regular sports shoes, despite being sandal-type. [Means for solving the problem]

[0006] In order to solve the above problem, the invention described in claim 1 is a sandal-type medical care shoe comprising an upper part with a heel part located at the rear of the opening and an instep part located at the front of the opening, the outer surface of which is made of synthetic leather, and a sole part located below the upper part and on whose upper surface an insole is placed, characterized in that the upper part is provided with an instep height adjustment mechanism for adjusting the height of the instep, an instep adjustment mechanism for adjusting the size around the instep, and a heel adjustment mechanism for adjusting the size around the heel.

[0007] Therefore, according to the invention described in claim 1, three types of adjustment mechanisms are provided: an instep height adjustment mechanism, an instep circumference adjustment mechanism, and a heel circumference adjustment mechanism. This allows the instep height, instep circumference, and heel circumference to be adjusted appropriately to fit the user's foot. Therefore, although it is basically a sandal type that is easy to put on and take off and highly convenient, it is difficult to slip off and provides a fit similar to that of ordinary sports shoes.

[0008] The gist of the invention described in claim 2 is that in claim 1, the instep height adjustment mechanism is configured to include a tongue that protrudes from the rear end of the instep and can be bent forward, a first hook-and-loop fastener for fixing the tongue that is provided at the tip of the tongue, and a second hook-and-loop fastener for fixing the tongue that is provided on the surface of the instep and to which the first hook-and-loop fastener for fixing the tongue can be detachably engaged.

[0009] The invention described in claim 3 is based on claim 1, and its gist is that the instep adjustment mechanism is configured to include an instep belt that is arranged to extend in the shoe width direction on the surface of the rear end of the instep and has its base end fixed to the midfoot, a third hook-and-loop fastener for fastening the instep belt that is provided at the tip of the instep belt, and a fourth hook-and-loop fastener for fastening the instep belt that is provided on the surface of the midfoot and to which the third hook-and-loop fastener for fastening the instep belt is detachably engaged.

[0010] The invention described in claim 4 is based on claim 1, and is characterized in that the heel adjustment mechanism is a belt-shaped member made of synthetic leather, has a length adjustment metal fitting and an expandable section, and includes a back band for holding the heel, both ends of which are rotatably supported near the boundary between the midfoot and rearfoot sections, and the back band is located near the rear end of the opening and above the heel section to hold the heel.

[0011] The gist of the invention described in claim 5 is that in claim 4, the back band can be rotated to be in one of a use state where it is located near the rear end of the opening and above the heel portion to hold the heel, a forward retracted state where it overlaps with the surface side of the rear end of the instep portion to reinforce the rear end of the instep portion, and a rear retracted state where it overlaps with the outer surface side of the heel portion to reinforce the heel portion.

[0012] The gist of the invention described in claim 6 is that in any one of claims 1 to 5, the heel portion is 30 mm or more in height and is formed using a material that is harder than the midfoot portion, and the insole is a three-dimensional insole with a raised portion on the periphery, and the raised portion is positioned in contact with the inner surface of the heel portion to reinforce the heel portion. [Effects of the Invention]

[0013] As described above in detail, according to the inventions described in claims 1 to 6, medical and nursing shoes can be provided that have a fit similar to that of ordinary sports shoes, despite being sandal-type. [Brief explanation of the drawings]

[0015] Hereinafter, nurse shoes 11 according to one embodiment of the medical care shoes of the present invention will be described in detail with reference to Figs.

[0016] The nurse shoes 11 of this embodiment are shoes primarily used by nurses in medical settings. As shown in Fig. 1, the nurse shoes 11 include an upper part 12 and a sole part 13. The upper part 12 is a part that entirely covers the instep of the foot. The sole part 13 is located below the upper part 12, and an insole 14 is placed on the upper surface.

[0017] 1 and 2, the upper part 12 includes an upper part main body 27. The upper part main body 27 is the main part of the upper part 12, and is composed of a forefoot part 21, a midfoot part 22, and a rearfoot part 23, with the outer surface formed of synthetic leather. Synthetic fiber is provided on the inner surface side of this synthetic leather.

[0018] The color of the upper body 27 is not particularly limited and any color can be selected, but in this embodiment it is white, taking into consideration that it will be used in medical settings where cleanliness is required.

[0019] An opening 24, which is the part where the foot is inserted when putting on the shoes, is formed above the rear foot part 23 of the upper body 27. A heel part 25 is located behind the opening 24. The heel part 25 belongs to the rear foot part 23. An instep part 26 is located in front of the opening 24. The instep part 26 belongs to the forefoot part 21 and midfoot part 22.

[0020] As shown in FIG. 1 etc., the upper part 12 is provided with an instep height adjustment mechanism 31 for adjusting the height of the instep, an instep adjustment mechanism 41 for adjusting the size around the instep, and a heel adjustment mechanism 51 for adjusting the size around the heel.

[0021] As shown in FIGS. 1 and 2, the instep height adjustment mechanism 31 includes a tongue 32, a first hook-and-loop fastener 33 for fastening the tongue, and a second hook-and-loop fastener 34 for fastening the tongue. The tongue 32 is a tongue-like structure protruding from the upper rear end of the instep 26 and is foldable forward. Slits 28 are formed on both sides of the tongue 32 in the instep 26. The first hook-and-loop fastener 33 for fastening the tongue is fixed to the tip of one side of the tongue 32 by adhesive or sewing. The second hook-and-loop fastener 34 for fastening the tongue is fixed to the upper surface of the instep 26 by adhesive or sewing. The first hook-and-loop fastener 33 is removably fastened to the second hook-and-loop fastener 34. For example, if the tongue 32 is folded with the tip of the tongue positioned relatively far back and the fasteners 33, 34 are fastened together, the instep height is adjusted to a lower position. Conversely, when the tongue 32 is folded with the tip of the tongue positioned relatively forward and the fasteners 33, 34 are fastened together, the height of the instep is adjusted to be higher.

[0022] As shown in FIGS. 1 and 2, the instep adjustment mechanism 41 includes an instep belt 42, a third hook-and-loop fastener 43 for fastening the instep belt, and a fourth hook-and-loop fastener 44 for fastening the instep belt. The instep belt 42 is a belt-shaped member having a tip 42b and a base 42a. The instep belt 42 is positioned on the surface of the upper rear end of the instep 26, posterior to the second hook-and-loop fastener 34, and extends in the shoe width direction. The instep belt 42 is positioned in a sandwiched state inside the folded tongue 32. The base 42a of the instep belt 42 is fixed to one side surface of the midfoot portion 22 by adhesive or sewing. The third hook-and-loop fastener 43 is fixed to the underside of the tip 42b of the instep belt 42 by adhesive or sewing. The fourth hook-and-loop fastener 44 is attached to the other side surface of the midfoot portion 22 by adhesive. The fourth hook-and-loop fastener 44 is removably fastened to the third hook-and-loop fastener 43. For example, when the fasteners 33, 34 of the instep belt 42 are fastened together with the tip 42b positioned relatively high, the size around the instep is adjusted to be larger (i.e., looser around the instep). Conversely, when the fasteners 33, 34 of the instep belt 42 are fastened together with the tip 42b positioned relatively low, the size around the instep is adjusted to be smaller (i.e., tighter around the instep).

[0023] As shown in FIGS. 1 to 3, the heel adjustment mechanism 51 includes a back band 52 for holding the heel. The back band 52 is a strip-shaped member made of synthetic leather and has a length adjustment fitting 53 and an expandable portion 54. In this embodiment, a fastening rubber sole material is used for the expandable portion 54. The width of the back band 52 is not particularly limited, but in this embodiment, it is set to a dimension slightly smaller than the height of the heel portion 25. Specifically, the height of the heel portion 25 is set to approximately 30 mm to 40 mm, and the width of the back band 52 is set to approximately 20 mm to 30 mm. Both ends of the back band 52 are attached to the boundary between the midfoot portion 22 and the rearfoot portion 23 using eyelets 55. As a result, the back band 52 is pivotally supported.

[0024] As shown in Figure 5, the back band 52 is rotatable so as to be in an in-use state, a forward retracted state, or a rear retracted state. Specifically, when the back band 52 is positioned near the rear end of the opening 24 and above the heel portion 25 (i.e., in use position P1), the heel is supported (see Figure 5(a)). When the back band 52 is positioned overlapping the surface side of the rear end of the upper portion 26 (i.e., in forward retracted position P2), the thickness of the rear end of the upper portion 26 is increased for reinforcement (see Figure 5(b)). When the back band 52 is positioned overlapping the outer surface side of the heel portion 25 (i.e., in rear retracted position P3), the thickness of the heel portion 25 is increased for reinforcement (see Figure 5(c)).

[0025] In this embodiment, the heel portion 25 is formed using a harder material than the midfoot portion 22 so that it is less likely to deform when stepped on. Specifically, the hardness is increased by providing a hard, flat core material in the inner layer of the midfoot portion 22.

[0026] 3 and 4, the insole 14 used in this embodiment is a three-dimensional insole having a raised portion 14a at its periphery. The raised portion 14a is disposed in contact with the inner surface of the heel portion 25, thereby reinforcing the heel portion 25. In this embodiment, the insole 14 used is, for example, that disclosed in Utility Model Registration No. 3221483, but is not limited to this.

[0027] Therefore, according to this embodiment, the following effects can be obtained.

[0028] (1) As described above, the nurse shoes 11 of this embodiment include an upper portion 12 and a sole portion 13. The outer surface of the upper portion 12 is made of synthetic leather, with a heel portion 25 located at the rear of the opening 24 and an instep portion 26 located at the front of the opening 24. The sole portion 13 is located below the upper portion 12 and has an insole 14 installed on its upper surface. The upper portion 12 is provided with an instep height adjustment mechanism 31 for adjusting the height of the instep, an instep adjustment mechanism 41 for adjusting the size around the instep, and a heel adjustment mechanism 51 for adjusting the size around the heel.

[0029] Therefore, the above-mentioned configuration provides three types of adjustment mechanisms: instep height adjustment mechanism 31, instep adjustment mechanism 41, and heel adjustment mechanism 51. This allows the instep height, instep size, and heel size to be adjusted appropriately to fit the user's foot. Therefore, although the nurse shoes 11 are basically sandal-type shoes that are easy to put on and take off and highly convenient, they are difficult to slip off and provide a fit similar to that of regular sports shoes.

[0030] (2) In the nurse shoes 11 of this embodiment, the instep height adjustment mechanism 31 includes a tongue 32 that can be bent forward, and a first hook-and-loop fastener 33 and a second hook-and-loop fastener 34 for securing the tongue. Therefore, with this configuration, the instep height can be adjusted relatively easily to the appropriate state by adjusting the relative fastening positions of the fasteners 33 and 34. Furthermore, the instep adjustment mechanism 41 includes an instep belt 42 that extends in the width direction of the shoe, and a third hook-and-loop fastener 43 and a fourth hook-and-loop fastener 44 for securing the instep belt. Therefore, with this configuration, the instep size can be adjusted relatively easily to the appropriate state by adjusting the relative fastening positions of the fasteners 43 and 44. Furthermore, the heel adjustment mechanism 51 includes a heel-supporting back band 52 that has a length adjustment metal fitting 53 and an expandable portion 54 and is pivotally supported at both ends. Therefore, with this configuration, the heel size can be adjusted relatively easily to the appropriate state.

[0031] (3) In the nurse shoes 11 of this embodiment, the back band 52 having the above-described structure can be rotated to any of the use position P1, the forward retracted position P2, and the rearward retracted position P3. Therefore, when the back band 52 is moved to the use position P1, for example, the heel can be securely held over a relatively wide area. This allows for a fit similar to that of regular sports shoes, making the nurse shoes 11 easy to walk in. Furthermore, when the back band 52 is moved to the forward retracted position P2 or the rearward retracted position P3, the back band 52 retracts from the opening 24 and does not get in the way, providing a fit similar to that of sandals. This provides an advantageous position for desk work, etc., and also allows the rear end of the instep 26 or the heel portion 25 to be reinforced.

[0032] (4) The nurse shoes 11 of this embodiment are made entirely of white material, which allows for a sophisticated and clean design that is well-received in the medical field.

[0033] It should be noted that the above-described embodiment is merely an example, and the present invention may be embodied in any manner that is not deviated from the spirit and scope of the present invention.

[0034] In the above embodiment, the color of each part of the nurse shoes 11 was white, but this is not limited to this, and it is of course possible to use a light color other than white (such as light blue, light green, light yellow, light pink, etc.).

[0035] In the above embodiment, the present invention is embodied in nurse shoes 11, but it may also be embodied in medical shoes worn by people other than nurses in medical settings (e.g., doctors, pharmacists, etc.), or in nursing shoes used for non-medical purposes (e.g., nursing care settings, etc.).
