Description

Height-adjustable slippers with double footrest bands with perforations

The present invention relates to slippers, and more particularly, to slippers with adjustable heights, which have a double footrest band with a cut line that allows the footrest band to be cut, thereby resolving the inconvenience of having to choose between existing slippers according to the user's various instep heights, i.e., foot thickness, and further resolving the inconvenience of opening and closing a bathroom door with a low threshold by the footrest band of the slippers when opening and closing the door.

Generally, bathroom slippers are made of injection-molded soft synthetic resin or foam resin, and the footrest and instep cover are either injected as one piece or injected separately and then assembled.

Most of the instep covers here are of an arc shape and protrude from the footrest.

The instep cover protrudes in an arc shape to allow the instep to easily fit when putting on slippers.

Previously, Utility Model Registration No. 459800 was for bathroom slippers, and a design was proposed to tilt the slippers to the side so that moisture from the footrest can easily drain.

This is done by forming a weight on the side of the slipper so that when the slipper is laid on its side, it remains in that state, allowing moisture from the footrest to flow to the side and be discharged.

However, since these conventional slippers tilt to the side, the slippers protrude high above the bathroom floor, which causes the slippers to get caught on the door when closing in bathrooms with low thresholds.

Also, even if it is not tilted to the side, the instep cover is designed in an arc shape and protrudes from the step, so it can get caught on the door if the threshold is low.

The threshold is the same height as the bathroom floor to the bottom of the bathroom door, but most thresholds are constructed to a height of 45 mm to 70 mm, and bathroom slippers are manufactured to a height of 80 mm to 100 mm, so the slippers tend to get caught on the door. Therefore, users have the inconvenience of having to move the slippers to the side of the door to prevent them from getting caught on the door and then close the door.

In addition, due to these inconveniences, there were cases where residents filed lawsuits against the construction company demanding that the threshold be raised and that repairs be made to the defects.

In addition, since bathroom slippers generally have a flat upper surface or a very gentle slope, there is a problem that when wearing slippers while wearing socks, the socks become wet because moisture remains on the upper surface of the lower sole of the slippers after use in the bathroom.

In addition, to prevent this, a separate drainage hole was made in the lower part of the slipper, but this had the problem that when used in a wet bathroom, moisture would rise to the upper surface of the lower part of the slipper through the drainage hole, causing the feet to get wet.

The technology that serves as the background for the present invention is Utility Model Registration No. 0308106, “Bathroom Slippers.”

The above background art proposes a 'bathroom slipper, characterized in that it includes an actuator that is installed on the heel of the slipper and is inserted into the interior of the heel of the slipper by being compressed by the body weight when the slipper is worn, and has multi-stage hollow tubes having different diameters that are slidably fitted together; and an elastic body that is installed inside the actuator and, when the slipper is taken off, causes the compressed hollow tubes to be restored after a predetermined period of time, thereby lifting the heel of the slipper and causing the slipper to stand up at an angle.'

However, the above background technology had problems such as the incline being used to remove moisture only when the bathroom slippers are taken off, making it impossible to remove moisture while in use, and the elastic body rusting or becoming damaged.

Korean Utility Model Registration No. 20-459800 Korean Utility Model Registration No. 20-0308106 Korean Patent Publication No. 10-2023-0045436 Korean Utility Model Registration No. 20-0494639

Hereinafter, a detailed description of the height-adjustable slippers having a double footrest band with a cutting line according to the present invention will be described with reference to drawings.

FIG. 1 is a perspective view of a height-adjustable slipper having a double footrest band with a cut line according to the present invention, FIG. 2 is a side cross-sectional view of a height-adjustable slipper having a double footrest band with a cut line according to the present invention, FIG. 3 is a perspective view of a height-adjustable slipper having a double footrest band with a cut line according to the present invention with the footrest band cut off, FIG. 4 is a side cross-sectional view of a height-adjustable slipper having a double footrest band with a cut line according to the present invention with the footrest band cut off, FIG. 5 is a use view of a height-adjustable slipper having a double footrest band with a cut line according to the present invention with a plurality of footrest bands provided, and FIG. 6 is a use view of a height-adjustable slipper having a double footrest band with a cut line according to the present invention with one of a plurality of footrest bands cut off.

First, the present invention is a limited-purpose invention developed with a focus on enabling the user to maintain or cut the footrest band so as to be suitable for various instep thicknesses of each user, and furthermore, resolving inconvenience in opening and closing a door depending on the height of the threshold depending on the presence or absence of the footrest band.

The present invention is largely composed of a main body (10) and a footrest band (20), similar to general slippers.

Most slippers are made of simple structures, and developing inventions for such slippers is very difficult and involves very detailed issues, so this point must be carefully and closely examined.

First, as shown in FIGS. 1 and 2, although it appears to be composed of a general slipper, the main body (10), which is a component of the present invention, is a component composed of a foot plate that the sole of the user's foot comes into contact with, and in the foot plate that the sole of the foot of the main body (10) comes into contact with, water discharge holes (100) are formed diagonally at a predetermined interval and a connecting plate (110) is provided between the water discharge holes (100) on both sides adjacent to each other, and in a state where the foot plate located at the lower end of the foot plate band (20) located at the front end of the entrance where the toes fit among the foot plate bands (20) is relatively lower than the foot plates at other positions and has a concave portion (120) formed therein, and the foot plate is provided with a relatively high foot plate at both ends of the foot plate, i.e., the toe end and the heel end, so that the concave portion (120) can be formed.

Looking at the structural features related to the combination of the main body (10) and the footrest band (20) as shown in the following Figures 1 and 2,

The invention includes a footrest band (20) having a partition slit hole (200) formed at a predetermined position on the upper side of each of the two footrest bands (20) so that the footrest bands (20) can maintain an independent form while being fixedly connected to both ends of the main body (10) at a predetermined position near the tip of the main body (10) so as to be inserted into the toes, and a slit (210) provided horizontally at a predetermined position at both ends of one or more of the footrest bands (20), and a cutting line (220) provided on both sides of the slit (210) so that the slit (210) and the partition slit hole (200) can be cut by being connected.

The cases of the above drawings 1 and 2 are slippers of the present invention that are applicable to users with a low instep, that is, users with a low foot thickness, and each component has its own functional role or effect, but there is no need for modification if the user is an average person.

In the cases of the above-mentioned FIGS. 1, 2, and 5, the threshold of the bathroom is relatively high, so that the slippers of the present invention do not get caught in the door gap or cause inconvenience in opening and closing the door, regardless of whether the bathroom door is opened or closed.

The function and role or effect of the present invention, along with its structural features, is to solve the problem of users who have relatively high insteps or thick feet and thus have difficulty accommodating their feet in the footrest bands of slippers worn by ordinary people, and people who have relatively low bathroom thresholds and thus have difficulty accommodating their feet in the door frame when opening and closing the bathroom door.

In conclusion, the purpose is to derive the final results of FIGS. 3 and 6 through the process of FIG. 4. To explain in detail, in order to solve the problem that it is difficult or inconvenient to accommodate between the footrest band (20) and the foot plate when the instep is thick, as shown in FIG. 4, the portions connected to the main body (10) on both sides of the footrest band (20) are cut along the cutting line (220), so that the cutting line (220) is connected to both ends of the partition slit hole (200), thereby making it possible to easily remove the footrest band (20).

In this way, when the footrest band (20) is removed, the footrest band (20) remaining in the front has a relatively narrower gap between the footrest surfaces than the removed footrest band (20), but since it is a part where the user's toes are received, it is not interfered with by the thickness of the instep, so that a user with a relatively thicker instep than the average person can easily use it, thereby solving the above problem, and in order to further improve this, a concave part (120) is provided in the part of the footrest where the toes are received, and a relatively high footrest is provided at both ends of the footrest, that is, the tip of the toes and the tip of the heel.

The above concave portion (120) maintains the maximum distance between the footrest band (20) that has not been removed and the foot plate, thereby preventing the occurrence of various foot shapes, i.e., interdigital neuroma. The interdigital neuroma refers to a disease in which pain occurs in the bottom of the index and middle fingers or in the bottom of the middle and ring fingers, and in severe cases, it can cause knee and spinal diseases. By allowing the above concave portion (120) to gently settle the site where the interdigital neuroma occurs, it will be possible to prevent interdigital neuroma at least.

In addition, even if the bathroom door threshold is relatively low when transformed into Fig. 3, the slipper does not get caught in the door frame when opening and closing the door, so the life of the slipper is extended and the inconvenience caused by the slipper getting caught between the door frame and the door is resolved.

Furthermore, in order to prevent deformation and the emission of odors and other environmental pollutants due to exposure to various chemical products such as detergents and exposure to light and other moisture in bathroom slippers,

The outer surface of the main body (10) and the footrest band (20) contains 15 to 55 wt% of silicon dioxide, 10 to 15 wt% of toluene (C ₆ H ₅ CH ₃ ), 1 to 3 wt% of butanone, 1 to 3 wt% of methyl isobutyl ketone, 10 to 15 wt% of butyl acetate, 5 to 10 wt% of propylene glycol methyl ether acetate, 0 to 1 wt% of ethanol, 1 to 5 wt% of ethanol benzene, 10 to 15 wt% of acrylic polyol, 1 to 4 wt% of polyester polyol, Includes a coating agent applied by mixing 5 to 10 wt% of xylene and 1 to 4 wt% of other additives.

Preferably, the coating agent is

Silicon Dioxide 15 to 55 wt%, Toluene (C ₆ H ₅ CH ₃ ) 10 to 15 wt%, Butanone 1 to 3 wt%, Methyl isobutyl ketone 1 to 3 wt%, Butyl acetate 10 to 15 wt%, Propylene glycol methyl ether acetate 5 to 10 wt%, Ethanol 0 to 1 wt%, Ethanol benzene 1 to 5 wt%, Acrylic polyol 10 to 15 wt%, Polyester Polyol 1 to 4 wt%, Xylene 5 to 10 wt%, Other additives Containing a mixture of 1 to 4 wt%, or

Even more preferably, the coating agent is,

1 to 37.9 wt% of polymer resin, 2 to 5 wt% of silicon dioxide, 15 to 20 wt% of toluene (C ₆ H ₅ CH ₃ ), 2 to 5 wt% of methyl isobutyl ketone, 5 to 10 wt% of butyl acetate, 2 to 5 wt% of propylene glycol methyl ether acetate, 0.1 to 4 wt% of ethanol, 2 to 5 wt% of ethanol benzene, 25 to 30 wt% of acrylic polyol, 3 to 5 wt% of polyester polyol, 3 to 5 wt% of xylene, It contains a mixture of 3 to 5 wt% of glycidoxypropyltrimethoxysilane.

Under optimal conditions, the above coating agent is

It includes a mixture of 1 to 44 wt% of polymer resin, 10 to 15 wt% of toluene (C ₆ H ₅ CH ₃ ), 1 to 5 wt% of methyl isobutyl ketone, 10 to 15 wt% of butyl acetate, 1 to 5 wt% of propylene glycol methyl ether acetate, 1 to 5 wt% of ethanol benzene, 30 to 35 wt% of acrylic polyol, 1 to 5 wt% of polyester polyol, 1 to 5 wt% of xylene, and 1 to 9 wt% of glycidoxypropyltrimethoxysilane.

The present invention, configured as described above, resolves the inconvenience of having to choose between existing slippers according to the thickness of the foot, i.e., the height of the instep, for each user by enabling the footrest band to be cut, and further, resolves the inconvenience of opening and closing the door by the footrest band of the slipper when opening and closing the door due to the low threshold of the bathroom.

Additionally, it stimulates or maintains a specific area of the sole, that is, it stimulates and protects the area of the metatarsophalangeal nerve to improve blood circulation, and further improves knee or spinal diseases, thereby having the effect of keeping the feet healthy.

Although the present invention has been described above by means of limited embodiments and drawings, it is to be understood that the present invention is not limited to the embodiments, and that various modifications and variations may be made from the above-described contents by those skilled in the art in the art.
