Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to room shoes made of a knitted fabric, and more particularly to room shoes (indoor shoes) that are excellent in shape stability and comfortable to wear.

Slippers are representative foot coverings for indoor shoes. This slipper consists of an insole member that directly contacts the sole of the foot when the foot is placed thereon, an instep member formed in a shape that wraps around the toes and the instep, and a lower side of the slipper that directly contacts the floor surface. It is composed of a bottom member that is in contact with, and a support member that positions and connects the insole member, the instep member and the bottom member.
In such slippers, since the rear part (heel part) of the foot is exposed without being covered, there is a problem that it is easy to come off unless some force is applied to the tip of the foot when walking. Especially when housewives move frequently for housework such as cooking and cleaning at home, the slippers often tend to come off and become unstable, and slip on the kitchen floor. There is a danger of falling over.

In order to solve the problem that slippers tend to slip off, indoor slippers (room shoes) have been used that are similar in shape to shoes that are difficult to slip off from the feet by increasing the portion that covers the feet.
For example, Japanese Patent Application Laid-Open No. 2016-049337 (Patent Document 1) filed by the applicant of the present application discloses room shoes that are comfortable to wear, less slippery, and less stuffy. The room shoes disclosed in Patent Document 1 are foot coverings for indoor use, covering the instep, the heel, and the sole, and exposing the ankle. a heel part covering the heel and a sole part covering the sole, an opening for putting in and taking out the foot is provided on the opposite side of the sole part, and the instep part includes a mesh fabric. and/or wherein the sole is formed from a quilted fabric.

JP 2016-049337 A

The room shoes disclosed in the above-mentioned Patent Literature 1 have been well received because they are comfortable to wear, less slippery, and less stuffy. However, since the fabric is sewn and formed, the waist of the fabric may weaken over time and it may be difficult to maintain the overall shape when not attached to the foot (for example, the sole and instep of the foot). When the space for inserting the toe tip between is closed). For this reason, the shape of the room shoes collapses when you put them on, so you may have to adjust the shape of the room shoes by hand and widen the opening to wear them. could have been difficult. The applicant of the present application diligently developed a room shoe disclosed in Patent Document 1, which has excellent shape stability and can maintain its overall shape even when it is not worn on the foot even over time.

The present invention has been developed in view of the above-mentioned problems, and the purpose thereof is to maintain the overall shape of the shoe even when it is not attached to the foot (for example, like indoor shoes) even after aging. To provide room shoes excellent in possible shape stability.

In order to achieve the above object, the room shoes according to the present invention take the following technical measures.
That is, the room shoes according to the present invention are room shoes that are foot coverings for indoor use, and include an instep part covering the instep, a foot side part covering the left and right sides of the foot, a heel part covering the heel, and a foot. It is formed by a sole that covers the sole, and is provided with openings for putting in and taking out the foot on the opposite side of the sole, and the instep, the side of the foot, the heel and the sole are heat-fused. It is characterized in that it is knitted using knitting yarn containing adhesive fibers, and can maintain its overall shape in a state in which it is not attached to the foot.

ADVANTAGE OF THE INVENTION According to the room shoes of the present invention, it is possible to provide room shoes with excellent shape stability that can maintain the overall shape even when they are not worn on the foot (for example, like indoor shoes) even with aging. .

Room shoes 100 according to embodiments of the present invention will be described in detail below with reference to the drawings. There are various structures of room shoes, and the present invention is not limited to a specific structure. For example, it does not matter what kind of structure the room shoes have, and what kind of pattern paper and sewing of the fabrics that make up the room shoes can be used. Therefore, the structure itself of this room shoe 100 shown below is merely an example.

1 is an overall perspective view of room shoes 100 according to the present embodiment, FIG. 2(A) is a side view seen from arrow 2A (see FIG. 1, hereinafter omitted), and FIG. 2(B) is an arrow 2B. 2(C) is a front view as seen from arrow 2C, and FIG. 2(D) is a rear view as seen from arrow 2D. These FIGS. 1 and 2(A) to 2(D9) all show the state in which the room shoes 100 are not worn.

As shown in these figures, this room shoe 100 is generally a foot covering for indoor use, and includes an instep part 110 that covers the instep, a foot side part 120 that covers the left and right sides of the foot, and a heel. It is formed by a heel portion 130 to be covered and a sole portion 140 to cover the sole, and an opening 150 for putting the foot in and out is provided on the opposite side of the sole portion 140 . Characteristically, the instep portion 110, the side portion 120, the heel portion 130, and the sole portion 140 are knitted using knitting yarn containing heat-fusible fibers (first characteristic), and the overall shape can be maintained even when the foot is not attached (second characteristic). Here, the sole portion 140 is a surface that comes into contact with the sole skin, and when the sole rubber G that comes into contact with the floor surface is provided, the sole portion 140 does not come into contact with the floor surface. If the sole rubber G that contacts the surface is not provided, the sole portion 140 will contact the floor surface. When the sole rubber G is not provided, it is necessary to reinforce the sole 140 by constructing it with multiple knitted fabrics. It is also preferable to configure it with a knitted fabric.

In addition, the heat-fusible fibers in the present invention are fused to each other at the contact portion of the heat-fusible fibers by heat setting described later, so that the fibers are not easily separated from each other, and the state of not being attached to the foot, which is the second feature. It is not limited as long as it can maintain the overall shape. For example, it may be what is called heat-fusible fiber or heat-fusible fiber. In the following description, these fibers are represented by heat-fusible fibers.

Room shoes 100 will be described in further detail.
More specifically, the instep part 110 forming the room shoes 100 is composed of an instep covering knitted fabric 110A covering the instep and a toe covering knitted fabric 110B covering the toe part. (the instep covering knitted fabric 110A and the toe covering knitted fabric 110B) are doubled because they are folded back at the opening 150. As shown in FIG.

More specifically, the foot side portion 120 forming the room shoes 100 is composed of an outer covering knitted fabric 120A on the outer side (opposite side to the skin contacting side) and an inner covering knitted fabric 120B on the inner side (skin contacting side). The leg side portion 120 is composed of a double knitted fabric.
More specifically, the heel portion 130 forming the room shoes 100 includes an outer covering heel knitted fabric 130A on the outer side (opposite side to the skin contacting side) and an inner covering heel knitted fabric 130B on the inner side (skin contacting side).
, and the heel portion 130 is composed of a double knitted fabric. In addition, a reinforcing knitted fabric is provided on the opening 150 side of the heel portion 130 . That is, the outer covering heel knitted fabric 130A is provided with a reinforcing knitted fabric 130AC, and the inner covering heel knitted fabric 130B is provided with a reinforcing knitted fabric 130BC.

More specifically, the sole portion 140 forming the room shoes 100 is composed of the inner (skin contacting side) sole knitted fabric (which may be double as described above). A sole rubber G made of hard rubber or the like is adhered to the opposite side of the knitted sole fabric to the skin-contacting side.
The room shoes 100 having such a configuration have a first feature that the instep portion 110, the side portion 120, the heel portion 130, and the sole portion 140 are knitted using knitting yarn containing heat-fusible fibers. It is mentioned that it is done. Therefore, in the instep part 110, the instep-covering knitted fabric 110A and the toe-covering knitted fabric 110B are knitted using knitting yarns containing heat-fusible fibers, and the foot side part 120 is knitted with the heat-fusible fibers. The outer covering knitted fabric 120A and the inner covering knitted fabric 120B are knitted using the knitting yarn containing the heat-fusible fiber, and the heel portion 130 is knitted using the knitting yarn containing the heat-fusible fiber. 130B is knitted, and the sole part 140 is knitted with knitting yarn containing heat-fusible fibers.

These knitted fabrics are sewn at the boundaries of the respective knitted fabrics along the sewing lines S so that the overall shape of the room shoes 100 shown in FIG. 1 is obtained. Then, before or after the heat setting described below, a sole rubber G made of hard synthetic rubber or the like is adhered.
This heat setting uses the thermal properties of the heat-fusible fibers contained in the knitting yarn to set the fibers in such a way that the fibers are fused together at the contact portion of the heat-fusible fibers and are difficult to separate. The purpose is to maintain the shape of the shoe 100 . This heat setting is performed under desired conditions (temperature, time, etc.) corresponding to the heat-fusible fiber. In this heat setting, the instep part 110, the side part 120, the heel part 130, and the sole part 140 (whether or not the sole rubber G is adhered) sewn along the sewing line S are made of metal. and heat-set according to desired conditions (temperature, time, etc.).

In addition, heat fusion means a state in which the heat-fusible fibers are fused and adhered to each other at the contact portion of the heat-fusible fibers due to heat or heat and pressure from the outside. It refers to a state in which at least some of the fibers are fused and adhered, or a state in which the fibers are adhered to each other even if they are not fused.
And, because it is thermally set in this way (first feature), the overall shape can be maintained even when it is not attached to the foot as shown in FIG. 1 (second feature). Here, this room shoe 100 can maintain its overall shape even if it is not worn on the foot even if it changes with time. It is characterized by having shape stability that conventional room shoes do not have.

Room shoes 100 having the first and second characteristics as described above are manufactured as follows.
