Description

Stabilization of pressure dispersion structure Reinforcing material for toe cap {omitted}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a reinforcement for attaching to a toe cap built in a safety net to secure workability and safety of an operator.

Typical stabilizers have a built-in toe cap to protect the operator's feet from hazards in harsh environments such as industrial sites.

In particular, when a heavy object falls on a wearer's foot, a built-in toe cap for protecting the foot of a worker is generally formed as a dome structure having a space surrounded by a metal material and capable of receiving a toe portion.

Such a toe cap is effective in protecting the toe of an operator when a heavy object falls on a foot of a worker or when a toe is struck against a solid object. However, due to the structure of the toe cap, it is impossible to respond appropriately according to the posture of the user, ≪ / RTI >

That is, as shown in Fig. 7, in the workplace where the knee-bending operation frequently occurs, the foot of the worker frequently contacts with the top of the toe cap, and the toes and the toe side portions of the toe- It causes a pain of a worker, and the work efficiency is very low.

The present invention addresses this problem and proposes a safety reinforcement that functions to prevent pain from occurring to the operator by protecting the foot or the toe of the foot and the side surface of the foot by being coupled to a toe cap built in the safety shoes used in the past.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the scope of the present invention should be understood from the description of the claims. Further, the description of known technology which obscures the gist of the present invention is omitted.

In the description of the present invention, "direction", "lower", "rearward", and the like are defined based on the foot of a person, and the direction of the toe is referred to the front, the heel toward the rear, It was caught.

The present invention relates to a safety cap for a safety cap (200), which is attached to a toe cap (100) formed inside a safety cap and protects the foot by wrapping around the toe and the foot.

FIG. 1 is a perspective view of a reinforcing member for a safety toe cap according to an embodiment of the present invention, FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a bottom view of FIG.

As shown in FIG. 1, the toe cap 100 to which the reinforcing member of the present invention is attached is formed as a dome-like shape having a rear opening as shown in FIG. At this time, the cut surface on the side of the instep 130 which is the upper side of the cut surface 130 is referred to as the upper cut surface 131, and the cut surface contacting the side of the thumb or the toe of the cut surface 130 is referred to as a side cut surface 132.

2 and 3, the stiffener 200 is composed of a step joining material 210 and a pressure dispersing material 220.

9 is a view showing a process of joining a toe cap and a step joint.

As shown in FIG. 9, the stepped joint 210 is coupled to the toe-cap inner surface 120 along the cut surface 130 of the toe cap, and a part of the stepped joint 210 is exposed to the rear of the toe cap. When the step of the hard toe cap contacts the foot of the wearer, It is a role to play. That is, the stepped portion of the portion extending from the inner surface 120 to the cut surface 130 of the toe cap is sharp and rigid, causing skin damage and pain, due to physical friction at a portion directly contacting the foot as shown in Figs. 5 and 8 . At this time, if the step joint material 210 is partially attached to the inner surface 120 near the cut surface 130 and a part of the step joint material 210 is exposed to the rear of the toe cut surface, The step of the portion leading to the foot portion 130 does not directly touch the foot, thereby relieving the pain. In order for such an effect to be exhibited properly, the damper 210 should have a predetermined thickness and be made of an elastic material which is flexible and not folded.

The stepped joint 210 may be divided into an upper support surface 211 exposed rearward from the upper cut surface 131 of the toe cap and a side sidewall 212 exposed rearward from the side cut surface 132 of the toe cap. have.

Fig. 4 is a side elevational view of Fig. 1 and a cross-sectional enlarged view of the toe cap and the stiffener coupling portion. Fig.

As shown in FIG. 4, it is preferable that the length s1 that the upper support surface 211 is exposed rearward is equal to or greater than the toe cap thickness t1. However, since the flexibility by the pressure-dispersing material 220 can be sufficiently secured when the foot is bent so as to be shorter than the lateral width f1 of the pressure-dispersing material 220, the relationship t1? S1 < Accordingly, the upper support surface 211 is joined with and supports a part of the upper surface of the pressure dispersing member 220. The toe cap 100 and the pressure dispersing member 220 can be separated from each other by a gap between the cut surface 130 of the toe cap 100 and the pressure dispersing member 220, It is a role to combine. It is more preferable to combine the air tube 221a described below with a relationship of t1 = s1 in terms of cost reduction and flexibility of the pressure dispersion material 220. [

The side sidewall 212 is formed by continuing the exposed surface from the upper support surface 211 to the side cut surface 132 of the toe cap and is also preferably greater than or equal to the toe cap thickness t1. At this time, when the length s2 extending to the rear of the toe cap is formed to be longer than the width f1 of the pressure dispersing member 220 (s2> f1), the side fringe scene 212 is divided into the large toe and the small toe side Since the plurality of air tubes 221 constituting the pressure dispersing member 220 are joined at the side surfaces thereof, the stiffener 200 can maintain a stable structure and thus the durability can be improved.

According to the above-described configuration, the pressure applied by the cut surface 130 of the toe cap to the foot is firstly dispersed by the step jointing material 210 in accordance with the foot movement of the safety foot wearer. This is to disperse the pressure on the foot by widening the area of the portion of the cut surface 130 that directly touches the foot (pressure is inversely proportional to the area).

In addition, the pressure dispersion material 220 is secondarily dispersed by buffering action, which is caused by the following structure of the pressure dispersion material 220.

The pressure dispersing member 220 is coupled along the cut surface 130 of the toe cap at an upper portion of the stepped joint 210 exposed rearward of the toe cap as a thickness corresponding to the toe cap thickness t1. The pressure dividing member 220 and the toe cap 100 are integrally joined to each other in a state of being in contact with the cut surface 130 by being attached to the step joining member 210 without being directly coupled to the cut surface 130. [ This is because the lower surface of the pressure dispersing member 220 and the inner surface of the toe cap 100 are attached to the stepped joint 210 but may be directly attached to the cut surface 130 of the toe cap.

Figure 10 is an embodiment of a pressure distributor and Figure 11 is a view of another embodiment of a pressure distributor.

The pressure distributor 220 may include a plurality of air tubes 221 as shown in FIG. The air tube 221 is made of a material having flexibility and elasticity, and is formed as a tube through which the center passes and air can flow. That is, after a plurality of, preferably four to five, elastic straw-like air tubes 221 are joined, the air pipes 221 corresponding to the bent shape of the cut surface 130 and the upper So as to be adhered to the step joining member 210. At this time, the outer diameter f2 of each air tube 221 is designed to correspond to or more than the toe cap thickness t1 (f2? T1). Therefore, when the toe cap is attached to the shoe upper, the space between the shoe upper and the upper support surface 211 is changed to improve the comfort. Concretely, when the upper support surface 211 relaxes the impact caused by the step of the toe cap 100, a synergy effect due to the pressure dispersing member 220 can be obtained. In addition, as shown in FIG. 7, when the user lifts the heel and bends the foot, the top of the foot may be folded to stimulate the user's feet. The pressure dispersing member 220 functions to buffer the foot as shown in FIG.

As described above, the pressure dispersing member 220 may be formed by combining a plurality of independent air tubes 221 as described above. However, as shown in FIG. 11, a plurality of air pipes 223 may be embedded therein And an air band 222 made of an elastic material such as silicone may be formed to have a thickness equal to or greater than the toe cap thickness t1. The thickness of the end portion of the airbag 222 contacting the toe cut surface 130 may be designed to be the same as the toe cap thickness t1 but is preferably designed to be slightly larger than the toe cap thickness t1, Do. The built-in air pipe 223 is an indispensable component because it can reduce the cost, provide a buffering effect, and flexibly cope with various thicknesses of the toe cap. If you want to use a regular rubber band, you need to put several sheets, so the workability is poor. The thick rubber band with a single body does not have a good cushion feeling because there is no air layer.

12, an airbag 222 of an elastic material having an air pipe 223 therein is formed to have a thickness equal to or greater than the toe cap thickness t1, and the air pipe 223, Is formed to be thinner (smaller in diameter) toward the rear. In other words, when the three air pipes 223a, 223b, and 223c are formed, the thickness of the air pipe (diameter of the air pipe) is as follows.

The first air pipe 223a> the second air pipe 223b> the third air pipe 223c,

The first air pipe 223a near the toe-cut surface 130 is thick to fill the gap between the cut surface 130 and the foot so that the foot does not directly touch the cut surface 130. On the other hand, the third air pipe 223c is thin Is intended to provide more space for the feet to be seated and to allow more flexibility in the movement of the feet as shown in Fig.

In other words, the air band gradually becomes thinner toward the rear than the air bag, and the pressure applied from the toe-cut surface 130 to the foot is gradually dispersed when the foot is turned over.

11 and 12, the air pipe 223 does not extend to the side end portions of the air bands 222 but has flat side fills 224 on both sides of the air bands 222 ) May be formed.

At this time, both end portions of the air pipe 223 are connected to the side filler surface 224 in a curved shape, which is preferable in terms of wear comfort. In a more preferred form, as shown in FIGS. 12 and 13, the thickness of the air pipe is designed to be smaller toward the end of the air pipe 223. As a result, the air pipe 223 is more naturally connected to the side filler surface 224, thereby maximizing the feeling of fit.

The thickness of the side fill surface 224 is designed to be equal to or greater than the thickness t1 of the toe cut surface 130. Preferably, it is designed to be slightly thicker than the toccom cut surface thickness t1 to correspond to the cut surface thickness t1 of the toe cap when the side fill surface 224 is compressed. Further, the thickness of the side filling surface 224 contacting the cut surface 130 is equal to or greater than t1. When the thickness of the side filling surface 224 decreases toward the rear side, a space for the feet to be seated is further secured.

The present invention has the following effects.

In other words, it is formed of a flexible material at a portion contacting with the foot so as to protect the toe part and the toe part of the worker by being joined to the toe cap built in a commonly used safety foot, It is possible to improve the work stability and work efficiency of the worker by effectively protecting the feet by combining the structures.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be clear to those who have knowledge.
