BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an impact absorbing lanyard for an industrial safety swing, and more particularly, to an impact absorbing lanyard for an industrial safety swing capable of improving workability of an operator.

Generally, when an operator performs an operation in a structure installed at a high position from the ground such as a construction site for building a high-rise structure such as a building or a bridge, a shipyard for drying a large ship, It is obligatory to wear personal safety protective gear such as safety belts and safety helmets as safety protective gears in order to protect workers from danger such as falling accidents.

In this case, the seat belt for high work is used by fixing a hook-shaped hook connected to the shock absorbing lanyard to the safety band and the fixed support band. The shock absorbing lanyard is provided with various shock absorbing devices, .

Conventional shock absorber lanyard was designed to prevent a worker from crashing by hanging one end of a rope made of twisted material such as natural fiber or synthetic fiber to the worker and hanging the other end to a fixed support base . However, since the conventional shock-absorbing lanyard is used in a long and loose state, it interferes with work activities of a worker, and there is a problem that a heavy load generated at the time of a fall is directly applied to an operator, resulting in injury to an operator.

In order to solve such a problem, Korean Patent No. 10-1510537 discloses a safety rope fabric composed of an elastic portion of a double fabric and a weaving portion woven with synthetic fibers, which is used for a safety belt for high- A weaving part having a tubular fabric made in a weaving shape and having a tubular shape, a weaving band embedded in the tubular fabric to give elasticity, and a hook ring for folding the upper part with the foaming band embedded therein, And a folded lower portion to complete the elastic portion formed by the corrugated portion.

Korean Patent Registration No. 10-1637149 discloses a safety belt fabric composed of an elastic portion of a double fabric and a woven portion woven with a synthetic fiber yarn used in a safety belt for high work work wherein a plurality of synthetic fiber yarns, A tube fabric embedded in the tubular fabric and having a width less than the width of the tubular fabric and provided with resilience, and a foil blank having a built-in foil paper which is condensed by the heat to be heated, Wherein the tubular fabric is made up of a weaving portion having a wider area with respect to the upper, lower or one side of the elastic portion formed on the base of the foil synthetic paper, and the weaving portion sequentially folds the upper and lower portions to bind the carabiner A hook ring which binds the hook of the carabiner ring and the foil ring, A seat belt is made by weaving a warrior with a weft and a ramp, embedding it in a tube fabric, sewing the upper and lower ends, and adjusting the stretchability together with the tube fabric.

However, according to the prior art, when a force is applied to the inside of the tubular fabric, the length of the seat belt is reduced by accommodating a foaming band or foil paper woven with an elongated foil, but still has a long length There is a problem that work convenience of the operator is deteriorated.

Accordingly, there is a demand for an impact absorbing lanyard for an industrial safety swing that can shorten the length of the impact absorbing lanyard to improve the workability of the worker and absorb the impact applied to the worker at the time of falling.

Fig.

1, the shock absorbing lanyard 100 for an industrial safety swing according to the first embodiment of the present invention includes one carabiner 110 connected to an industrial safety swing, two hooks 130 A foil sealer 150 which extends to both sides of the carabiner 110 and is coupled to one end of the carabiner 110 and the other end to the hook 130 to absorb an impact, (Not shown).

2, the shock absorbing lanyard 100 for an industrial safety swing according to the second embodiment of the present invention includes one carabiner 110 connected to an industrial safety swing, one hook A foil cover 150 having one end coupled to the carabiner 110 and the other end coupled to the hook 130 to absorb the impact and a protective cover 170 housing the foil cover 150 .

The industrial safety swing is worn on the body of the worker and consists of a shoulder belt, a chest belt, a waist belt, and a leg belt. The impact absorbing lanyard (100) absorbs the impact when the weight of the worker is applied in the event of a fall, because the puller (150) is stretched.

The carabiner 110 according to the present embodiment is bound to one end of the poiella shovel 150 and fastened to the swing hanger A of the industrial safety swing or the back of the operator.

The hook 130 according to the present embodiment is coupled to the other end of the poiella shoe 150 and fastened to a fixed support or the like to prevent an operator from falling down during operation.

In the event of a fall, the weight of the worker and the load increased due to the acceleration are transmitted to the foiler shoe 150 through the hook 130. In addition, the Poilera shaver 150 is extended in the longitudinal direction to absorb shock when a load is transmitted due to a fall accident.

The foiler shoe 150 according to the present embodiment is woven with the foam 151, the synthetic fiber 153 and the rubber yarn 155 to absorb the impact and has a corrugated shape in the longitudinal direction by the rubber yarn 155 .

In addition, the Poilera shaver 150 according to the present embodiment alleviates and absorbs the impact applied to the operator while the rubber warp yarn 155 is primarily elongated in the longitudinal direction with respect to the transmitted impact load, Is elongated in the longitudinal direction to mitigate and absorb the impact on the operator. Therefore, a strong impact applied to the operator at the time of a fall accident can be firstly absorbed and absorbed by the rubber yarn 155 in a second manner, and strong impact can be prevented from directly being applied to the operator.

3, one end coupled to the carabiner 110 of the foil shell 150 and the other end bound to the hook 130 are doubly woven, and the middle portion of the foil shell 150 Woven with a tube fabric.

The width W1 of one end and the other end of the foil stripper 150 is less than the width W2 of the middle portion of the foil stripper 150.

The middle portion of the foil shell 150 is woven with a tube fabric but the lower fabric D of the tubular fabric and the upper fabric U are in close contact with each other. W1 is smaller than the width W2 of the middle portion of the foil roller. This is because one end of the foil shell 150 forms a carabiner ring bound to the carabiner 110 and the other end of the foil shell 150 is connected to the foil shell 150 ) The width W1 of the one end portion and the other end portion is formed to be smaller than the width W2 of the middle portion of the foil sealer 150. For example, the width W1 of one end of the foil shell 150 and the width W2 of the foil shell 150 may be in the range of 24 to 26 mm and 38 to 40 mm, respectively.

To this end, the density of the weft yarn 153 at one end and the other end of the weirer shoe 150 is less than the density of the weft yarn 153 at the midpoint of the weirer shawl 150. Specifically, the density of the weft yarn 153 at one end and the other end of the weiler roll 150 is 8 / inch, the density of the weft yarn 153 at the middle portion of the weiler roll 150 is 10 / Inch. ≪ / RTI >

On the other hand, when the worker operates the worker while the impact absorbing lanyard 100 is connected to the industrial safety swing, if the length of the impact absorbing lanyard 100 is long, the work activity of the worker is hindered and the workability is lowered.

In order to shorten the length of the foil sealer 150 connecting the hook 130 with the carabiner 110 before the impact load is applied in order to improve the workability of the operator, Is formed to be corrugated. To this end, as described above, the foiler shoe 150 according to the present embodiment wraps the foam yarn 151 and the synthetic fiber yarn 153 together at the intermediate portion to wrinkle.

Referring to FIGS. 4 and 5, the weaving state of the tube fabric in the middle portion of the foiler shoe 150 according to the present embodiment will be described below.

As shown in FIG. 4, the tube fabric constituting the middle part of the poilla shawl 150 is a warp yarn 151 and the synthetic yarn 153 is used as a weft yarn.

Also, the rubber yarn 155 is disposed between the warp yarns 151 so as to be spaced apart from each other.

The rubber yarn 155 is arranged in parallel between the deformable unit members S in the case where four to eight deformable members 151 arranged in parallel in this embodiment are used as one deformable unit S do. The rubber warp yarns 155 are arranged repeatedly and side by side between the deformable unit pieces S, preferably with eight deformable members 151 as one deformable unit S, This results in excessive wrinkles in the tubular fabric when repeatedly placing the rubber yarn (155) between the foam units (S) with less than four foragers (151) as one foam unit It is difficult to form the wrinkles of the tube fabric when the rubber yarn 155 is repeatedly disposed between the deformable unit S by using the deformer 151 as a single deformer unit S as shown in Fig.

The tube fabric constituting the middle part of the foiler shoe 150 according to the present embodiment is formed by weaving a rubber yarn 155 together with a warp yarn 151 and a weft yarn 153. At this time, the rubber yarn 155 is repeatedly woven or not woven with the synthetic fiber 153 as the weft. That is, when the rubber yarn 155 is woven with the synthetic fiber 153, which is a weft, it functions as a warp, and when it is not woven with the synthetic fiber 153, it functions as an examination.

5, the rubber yarn 155 is a warp yarn, which is located on the upper fabric U of the tubular fabric and is continuously arranged in two to four weft yarns 153, (U) and the lower fabric (D) of the tube fabric at a predetermined distance. And the rubber yarn 155 is woven into the underside of the two to four weft yarns 153 located in the lower fabric D of the tubular fabric as a warp yarn, And the lower fabric D, as shown in Fig. The rubber yarn 155 repeats the above-described operation and is held together with the foam 151 and the synthetic fiber 153 to form the foil sealer 150 to be wrinkled.

Preferably, the rubber yarn 155 is woven into the upper side of the synthetic fiber 153, which is the three weft yarns located in the upper fabric U, and the upper yarn 155 is woven by a predetermined distance corresponding to the interval between the synthetic fibers 153, (U) and the lower fabric (D) and is woven into the lower side of the synthetic fiber (153), which is three wefts located in the lower fabric (D).

This is because it is difficult to wrinkle the foiler shoe 150 when the rubber yarn 155 is woven to the upper side or the lower side of the single fiber weave 153 and the upper side or the lower side of the synthetic fiber 153, A problem may occur that the rubber yarn 155 is pulled out of the tubular fabric in the case of lacquering and the rubber yarn 155 may be broken due to friction with the inner surface of the protective cover 170. [

On the other hand, the rubber yarn 155 is woven in an elongated state at 70 to 90% of the total elongation length.

As described above, the woven state of the double knit fabric at both ends of the poilla shawl 150 continuous to the middle portion of the poilla shawl 150 will be described below.

Referring to FIG. 6, both ends of the foil roller 150 are woven in a double-woven form as described above. In this embodiment, the rubber yarn 155 is omitted and the warp yarn 151 and the synthetic yarn 157, which is a weft yarn and a pharmacist yarn, are wound around the weft yarns 151, Is used.

As described above, both ends of the foil shell 150 are woven so that the width of the foil shell 150 is wider than that of the middle portion of the foil shell 150. In other words, The density is 8 pieces / inch, and the density of the synthetic fiber 153 as the weft in the middle portion of the foil roller 150 is 10 pieces / inch.

In addition, the protective cover 170 according to the present embodiment is received in the foil shell 150 and is woven into a tube fabric using warp and weft yarns.

The protective cover 170 has a length corresponding to the length at which the foil sealer 150 is stretched by impact. Therefore, as shown in FIG. 7 (a), the foil shell 150 has a corrugated shape before it is stretched by the impact, so that the protective cover 170 also has a corrugated shape by the foil shell 150.

As shown in FIG. 7 (b), when the pulley 150 absorbs the impact due to the impact load due to the fall, the pulley 150 is stretched so that the length of the pulley 150 and the length The protective cover 170 surrounding the foil sealer 150 continuously absorbs the impact applied to the operator.

On the other hand, in this embodiment, the carabiner 110 coupled to the swing hanger A is prevented from being unlocked, and safety of the operator can be improved.

Referring to FIG. 8, the carabiner 110 according to the present embodiment includes a body 111 having an opening 112 formed thereon, a hinge member 112 which is rotatably coupled to one side of the opening 112 and is engaged with the other side of the opening 112 A main locker 113 that closes the opening 112 and a main locker 113 that is screwed to the main locker 113 and is advanced or retracted along the main locker 113 to be extrapolated or extrapolated to the other side of the opening 112, A broker 115 which is provided so as to protrude from the main locker 113 and which is adapted to advance in the other direction of the opening 112 and to open and close the opening 112, And a stopper 116 protruding when the main locker 113 is locked to the body 111 and hooked to the rear of the broker 115. The stopper 116 includes a protrusion 117 which is inserted into the groove 114 formed in the main locker 113 and projects to the outside of the main locker 113, And a spring member 118 that resiliently supports.

As shown in Fig. 8 (a), before the carabiner 110 is coupled to the swing hanger A, the protrusion 117 is depressed by the broker 115 into the groove portion 114 formed in the main locker 113 , The body 111 is hooked on the swing hook A to advance the broker 115 to connect the carabiner 110 to the swing hook A as shown in Figure 8 (b) The projection 117 protrudes outward from the main locker 113 and is engaged with the rear of the broker 115 to prevent the broker 115 from moving backward.
