It plays a role. That is, the stepped portion of the portion extending from the inner surface 120 of the tocap to the cutting surface 130 is sharp and hard, causing skin damage and pain due to physical friction on the portion directly touching the foot as shown in FIGS. 5 and 8. . At this time, the stepped joint member 210 is partially attached to the inner surface 120 near the cutting surface 130, and the part is coupled to be exposed to the rear of the tocap cutting surface, and the cut surface at the inner surface 120 by the stepped joint 210. The stepped portion of 130 does not directly touch the foot to relieve pain. In order to achieve this effect properly, the stepped joint material 210 may be formed of a predetermined thickness and have a flexible and non-folding elastic material.

- FIG. 4 is a side view of FIG. 1 and an enlarged cross-sectional view of the tocap and the reinforcing material coupling portion.
- the length s1 at which the upper support surface 211 is exposed to the rear side preferably corresponds to or exceeds the tocap thickness t1.
- the flexibility of the pressure dispersing material 220 may be sufficiently secured when the foot is bent when the width of the pressure dispersing material 220 is shorter than the width f1 of the pressure dispersing material 220.
- the upper support surface 211 is coupled to and supports a portion of the upper bottom surface of the pressure dispersing material 220. That is, while preventing the pressure dispersing material 220 from being separated downward, the toecap 100 and the pressure dispersing material 220 without a separate adhesive between the cutting surface 130 and the pressure dispersing material 220 of the to cap 100 It is a role to combine.
- it is more preferable to be combined with one of the air tubes 221a to be described later in relation to t1 s1.
- the side extension surface 212 is formed by connecting the exposed surface from the upper support surface 211 to the side cutting surface 132 of the to cap, and is preferably more than the tocap thickness t1. At this time, when the length (s2) extending to the rear of the tocap is formed longer than the width (f1) of the pressure dispersing material (220) (s2> f1), the side extension surface 212 is the side of the big toe and the little toe As well as more effective protection, and serves to couple the plurality of air tubes 221 constituting the pressure dispersing material 220 from the side, the reinforcement 200 can improve the durability by maintaining a stable structure.
- the pressure applied by the cutting surface 130 of the tocap to the instep of the foot of the safety shoe wearer is first dispersed in the stepped joint material 210. This is to spread the pressure on the foot by widening the area of the portion where the edge of the cutting surface 130 directly touches the foot (since the pressure is inversely proportional to the area).
- the pressure dispersing material 220 is coupled along the cut surface 130 of the to cap at the top of the stepped joint 210 exposed to the rear of the to cap as a thickness corresponding to the to cap thickness t1.
- the stepped joint 210, the pressure dispersing member 220, and the tocap 100 are integrally coupled to the cut surface 130 by being attached to the stepped joint 210. This is due to the lower surface of the pressure disperser 220 and the inner surface of the to cap 100 attached to the stepped joint material 210, but if necessary, the pressure disperser 220 may be directly attached to the cut surface 130 of the to cap.
- FIG. 10 is a view illustrating one embodiment of a pressure spreader
- FIG. 11 is a view illustrating another embodiment of a pressure spreader.
- the pressure dispersing material 220 may be composed of a plurality of air tubes 221 as shown in FIG.

That is, after combining a plurality of elastic straw-shaped air tubes 221, preferably 4 to 5, and corresponding to the bending shape of the cutting surface 130, at the same time the top of the stepped joint material 210 exposed to the rear of the tocap Bend to wrap it to attach to the stepped fitting material (210). At this time, the outer diameter f2 of each air tube 221 is designed to correspond to or larger than the tocap thickness t1 (f2 ⁇ t1).
- the to cap when the to cap is attached to the shoe upper, it serves to improve the fit by filling the space between the shoe upper and the upper support ground (211). Specifically, when the upper support surface 211 to mitigate the impact due to the stepped portion of the to cap 100, it may have a synergistic effect due to the pressure dispersing material 220. In addition, when the foot is bent to lift the heel as shown in FIG. 7, the upper of the foot may be folded to stimulate the foot. As shown in FIG. 6, the pressure dispersing member 220 may cushion the foot, thereby making the fit much better.
- the pressure dispersing material 220 may be combined with a plurality of independent air tubes 221 as described above to form a pressure dispersing material 220, a plurality of air pipes 223 therein as shown in FIG.
- the air band 222 of an elastic material such as silicon may be formed to have a thickness greater than or equal to the tocap thickness t1.
- the thickness of the end portion of the air band 222 which is in contact with the to cap cut surface 130 may be designed to be the same as the tocap thickness t1, it is preferable that the thickness of the air cap 222 be slightly thicker than the tocap thickness t1 in consideration of the compression of the silicon material. Do.
- the built-in air pipe 223 is an essential component is that it is cost-effective, has a good cushioning effect, and can flexibly cope with various thicknesses of the tocap.
- it is necessary to pad several sheets, so workability is inferior, and the one-piece thick rubber band does not have a good air cushion, which is not good.
- the air band 222 of the elastic material in which the air pipe 223 is built is formed to a thickness greater than or equal to the tocap thickness t1, and the air pipe 223 Is formed thinner (smaller diameter) toward the rear.
- the thickness (diameter of the air tube) of the air tubes is as follows.
- the thicker portion of the first air pipe 223a close to the to cap cutting surface 130 is intended to prevent the foot from directly touching the cutting surface 130 by filling between the cutting surface 130 and the foot, while becoming thinner toward the third air pipe 223c.
- the purpose of losing is to secure more space where the foot can be seated and to be more flexibly deformed by the movement of the foot as shown in FIG. 6.
- the air band is gradually thinner as the air pipe toward the rear is a structure that gradually disperses the pressure acting on the instep from the toecap cutting surface 130 when the instep is flipped.
- the side pipe surface (flat) is flat on both sides of the air band 222 without extending the air pipe 223 to the side end of the air band 222 ( 224 may be formed.
- both ends of the air pipe 223 to be curved to the side filling surface 224 in terms of wearing comfort. More preferably, as shown in FIGS. 12 and 13, the thickness of the air pipe becomes smaller toward the end of the air pipe 223. As a result, the air pipe 223 may be more naturally connected to the side filling surface 224 to maximize the fit.
- the thickness of the side fill surface 224 is designed to be equal to or greater than the thickness t1 of the tocap cutting surface 130. Preferably it is designed to be slightly thicker than the tocap cut surface thickness t1 so that the side fill surface 224 corresponds to the cut surface thickness t1 of the tocap when compressed. Further, the thickness of the side filling surface 224 in contact with the cutting surface 130 is more than t1, if the thinner toward the rear to secure more space for the foot can also be seated to feel the best fit.
