Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each drawing indicate like elements.

1 is a conceptual diagram showing the appearance of a toilet paper according to the present invention.

As can be seen from FIG. 1 , the toshi of the present invention includes a main body 100, a protection part 200, and a cover 300.

As shown in FIG. 1 , the body 100 is based on a cylindrical structure extending to a certain length. At this time, both side ends of the main body 100 form a cylindrical shape similar to a tunnel by being internally opened.

The main body 100 formed in a cylindrical shape in this way can be worn as if passing through the body of the wearer through the open ends of both sides. At this time, in the present invention, the wearer's body means the wearer's arm or leg, and the part where the protection unit 200 to be described later is located may be the wearer's elbow or knee.

The diameter of the main body 100 can be made of an appropriate diameter through which the wearer's body can pass and be worn. In addition, the length of the main body 100 can be of various lengths that can sufficiently cover the wearer's body. For example, the length of the main body 100 worn on the arm can reach the upper arm from the wrist to the elbow of the wearer. can be

In addition, since the main body 100 is made of a stretchable fiber material such as stretchable polyester fiber or spandex (rubber thread), it can be widely applied to various body thicknesses depending on the wearer.

That is, the main body 100 made of an elastic fiber material can increase in diameter so as to correspond to the thickness of the wearer's body when the wearer's body passes through. referred to as 'materials'.

A band 110 is included around both open ends of the main body 100 .

As can be seen in FIG. 1, the band 110 may be included in a strip shape along the circumference of both ends, and the band 110 is made of a 'second elastic material' that is more elastic than the first elastic material described above. It is done.

That is, the second stretchable material may be made of latex, synthetic rubber, or the like having greater elasticity than the first stretchable material, which is a stretchable fiber.

Since the band 110 made of the second elastic material has a stronger tendency to return to its original circumference after stretching as the wearer's body passes through it, it can fix the main body 100 to the worn position. .

In addition, the band 110 can be included in various ways, such as overlock processing on both ends of the main body 100 or folding both ends to accommodate the band 110 and then stitching.

The protection unit 200 is attached to one side of the side of the main body 100, preferably to the outer surface of the main body 100, and consists of a plurality of elastic blocks 210.

At this time, as mentioned above, the position where the protection part 200 is attached on one side of the main body 100 is attached to a part corresponding to the wearer's elbow or knee when wearing the cuff of the present invention to protect the wearer's joints. It is possible.

As can be seen in FIG. 1, the shape of the elastic block 210 may be the same as a hexagonal column, and the protection unit 200 in which a plurality of elastic blocks 210 are combined may form a honeycomb structure.

At this time, the honeycomb structure is a stable structure capable of evenly distributing shock and load through the six side surfaces of the hexagonal column, and the elastic block 210 made of the honeycomb structure can also add an aesthetic effect.

In addition, each of the elastic blocks 210 may be combined at a certain distance so as not to come into close contact with each other. Here, the certain distance means that the elastic block 210 can be pushed aside when it is impacted, and the elastic blocks located around it ( 210) means an appropriate distance to distribute the impact by delivering the impact.

The material of the elastic block 210 is made of an elastic material capable of alleviating and absorbing external impact, that is, the elastic material is chloroprene rubber, silicon rubber, Thiocol, Hypalon rubber (Hypalon rubber) and the like. Of course, it is not limited thereto, and may be made of various elastic materials. Such elastic materials will be described in more detail below.

The elastic block 210 may be attached to the main body 100 with adhesive, stitching, or the like, or detachably attached via a detachable means such as Velcro tape.

The cover 300 covers the protection unit 200 attached to the main body 100, and is made of a shape having a thin thickness and a certain area like a sheet, and the circumferential side of the cover 300 is coupled to the main body 100. (Connection) can form a space inside the cover 300.

At this time, the space of the cover 300 has a volume corresponding to the volume of the protection unit 200, so that it is possible to tightly cover the protection unit 200.

The part of the cover 300 coupled to the main body 100 is both (the cover 300 and the main body ( 100)) can be integrally combined.

The material of the cover 300 may be made of an elastic fiber material like the main body 100. The cover 300 made of an elastic fiber material is stretched together when the wearer moves the body and the protector 200 is opened to protect the wearer. It is possible not to feel discomfort, and when the protection unit 200 receives an impact, it is possible to assist in mitigating the impact by holding it so that it is not excessively pushed to the side.

Hereinafter, the functions and actions of the toshi of the present invention will be described based on this structure.

In order to easily understand the function and operation of the toshi of the present invention, the unique function and operation of the present invention will be described in comparison with a virtual (known) toshi to which the elastic block 210 is attached.

When a known toshi has only the elastic block 210 made of a single body, the elastic block 210 may act as a factor that hinders activity when the wearer moves the body due to structural characteristics made of a single body.

In contrast, the elastic block 210 of the present invention is divided into a plurality of pieces, so that when the wearer moves the body, the gap between the elastic blocks 210 widens and flexibly bends, so that it can be deformed to suit the human body structure. provides

Next, when the known toshi is provided with a plurality of elastic blocks 210 made of a square column shape, each elastic block 210 can be bent only in four directions, so that the impact applied to the elastic block 210 to the surrounding When distributing, since the impact can be dispersed only in four directions, there may be problems in that flexibility cannot be added to the movement of the body or that the impact is concentrated only in a specific direction.

On the other hand, the elastic block 210 of the present invention has a honeycomb structure that can face relatively many sides in a state in which the elastic block 210 is formed in a hexagonal column shape, and the impact applied to the elastic block 210 can be dispersed in six directions It not only disperses and relieves the impact applied to the wearer in multiple directions, but also provides characteristics that can be flexibly changed according to the movement of the body.

Then, when the known toshi is provided with a plurality of elastic blocks 210 made of a hexagonal column shape, but each elastic block 210 is in close contact without being spaced apart, it is easily sideways when an impact is applied to the elastic block 210 Since it is not pushed, there is a problem that the impact cannot be dispersed and alleviated to the surroundings.

In contrast, the torso of the present invention has a plurality of elastic blocks 210 spaced apart from each other by a predetermined distance, and when an impact is applied to the elastic blocks 210, the elastic blocks 210 mediate the space between the respective elastic blocks 210 It can be sufficiently bent to mitigate impact, and the space itself between each elastic block 210 not only serves as a shock absorber, but also performs an action of smoothly distributing impact to the surrounding elastic blocks 210.

In summary, the toe of the present invention has a honeycomb structure in which a plurality of elastic blocks 210 are spaced apart from each other to disperse and relieve the impact applied to the elastic block 210 in various directions, so that the impact is not easily transmitted to the wearer Characteristics can be provided, and when the wearer moves the body, it is possible to flexibly bend while widening the space between the elastic blocks 210, thereby providing ease of activity.

Figure 2 is a perspective view showing an example provided with an opening and closing portion in the cover of the present invention.

As can be seen from FIG. 2 , an opening/closing unit 310 is provided on one side of the cover 300 to open and close the space inside the cover 300 .

The opening and closing portion 310 may be provided along a portion where the body 100 and the cover 300 are connected. In FIG. 2, the opening and closing portion 310 made of a zipper is formed along the connection portion between the body 100 and the cover 300. An example that can open and close the space is shown.

Of course, the structure and configuration of the opening/closing unit 310 is not limited to that of FIG. 2 , and various opening/closing means such as snap buttons, Velcro, and magnets capable of opening and closing the space may be applied over part or the entirety of the cover 300. do.

Cover 300 including the opening and closing portion 310, when the elastic block 210 is damaged or to attach the elastic block 210 made of another elastic material, by opening a space through the opening and closing portion 310, the elastic block 210 ) to provide a property that can be replaced.

Figure 3 is a cross-sectional view showing that the upper surface of the elastic block and the inner surface of the cover are bonded.

As can be seen in Figure 3, the upper surface (hexagonal surface) of the elastic block 210 and the inner surface of the cover 300 may be bonded and fixed to each other.

At this time, as a method of bonding the upper surface of the elastic block 210 and the inner surface of the cover 300, various methods such as inserting and heating an adhesive sheet between the upper surface and the inner surface or applying an adhesive between the upper surface and the inner surface It is possible that this applies.

The upper surface of the elastic block 210 and the inner surface of the cover 300 bonded by this bonding method prevent the probability that the elastic block 210 can be deformed or damaged by being excessively pushed to the side or torn when an impact is received As well as blocking the occurrence of unnecessary space between the elastic block 210 and the cover 300, it provides a function so that the external force is directly transferred to the elastic block 210.

4 is a cross-sectional view showing an elastic block stacked on an elastic pad.

As can be seen in FIG. 4 , an elastic pad 220 may be attached to the surface of the main body 100, and an elastic block 210 may be provided as if it is stacked on the elastic pad 220.

The elastic pad 220 is attached to the surface of the main body 100 in a position corresponding to the protection unit 200 at a position where the protection unit 200 is provided, and can sufficiently absorb the impact applied to the elastic block 210 It is possible to have a certain thickness.

The material of the elastic pad 220 may be an elastic material having a higher modulus of elasticity than the elastic material of the elastic block 210, for example, a material such as methacrylic resin or vinylidene chloride resin.

When an impact is applied to the elastic block 210 in the vertical direction (pressing direction from top to bottom), the elastic pad 220 made of such a material preferentially compresses the elastic block 210 and relieves the impact, and the compressed elastic block ( 210), the elastic pad 220 offsets the force to return to its original shape, so that the shock to be applied to the wearer's body can be absorbed and the shock can be further alleviated.

That is, by attaching the elastic pad 220 to the surface of the body 100, the toshi according to the present invention provides a characteristic of adding the shock absorbing function of the elastic pad 220 in addition to the shock dispersing function of the elastic block 210.

Furthermore, the elastic material constituting the elastic block 210 of the present invention includes a material having a property of being stretched and bent, so that the impact applied to the elastic block 210 can be easily alleviated and dispersed.

At this time, the elastic block 210 may be made of any one of chloroprene rubber, silicon rubber, and Thiocol having physical properties as described above.

Here, chloroprene rubber is a synthetic rubber having an elongation rate of 200 to 600%, and is a material having a higher elongation rate than silicone rubber (200 to 500%) and thiocol (100 to 300%).

In addition, chloroprene rubber has a tensile strength of 300 to 700 kg/cm ² , and the tensile strength of chloroprene rubber is higher than that of silicone rubber (40 to 80 kg/cm ² ) and thiocol (70 to 130 kg/cm ² ). .

In other words, chloroprene rubber is a material suitable for realizing the shock mitigation function of the elastic block 210 through its excellent elongation and tensile strength. Hereinafter, a method of manufacturing the elastic block 210 including such chloroprene rubber will be described. do.
