To buffer.

Conventional shock-absorbing lanyards are designed to prevent workers from falling accidents that may occur during work by hung one end of a rope made of twisted materials such as natural fiber and synthetic fiber on the worker and the other end to a fixed support to prevent a worker's fall accident. . However, since the conventional impact-absorbing lanyard is used in a long and loose state, there is a problem in that the worker is injured by not only interfering with the work activity of the worker, but also by directly applying a strong load generated during a fall to the worker.

In order to solve this problem, Korean Patent Registration No. 10-1510537 discloses a safety rope fabric consisting of an elastic part of a double fabric used for a seat belt for high place work and a woven part woven with synthetic fiber yarn. Weaving but having a tube fabric in the shape of a tube, a poisa band that is embedded in the tube fabric to give elasticity, and a woven portion having a hook ring that folds and binds the hook to the upper part containing the poisa band, and the bottom of the hook ring A seat belt fabric with a cover or loop that folds in order to complete the elastic part formed by the corrugated part and then folds the lower part to bind the coverrina is disclosed.

Thus, the tube fabric is individually woven in the shape of a tube, the fabric has a width that is smaller than the width of the tube fabric and gives elasticity, and the fabric is condensed by the heat heated by the fabric. It includes an elastic part formed with a wrinkle part together, and the tube fabric consists of a woven part with a wider area with respect to an area on the upper, lower, or one side of the elastic part formed on the basis of the fabric, and the woven part sequentially folds the upper and lower parts to bind the carabiner. It forms a hook ring that binds the hook with the carabiner ring, and is made by weaving the cloth yarn with weft and warp, and the upper and lower ends are sewn inside the tube fabric, so that the expansion and contraction can be adjusted together with the tube fabric. Belt fabric is disclosed.

However, in the prior art, although the length of the seat belt fabric is shortened by accommodating a poisa band or pois yarn woven with a pois yarn that increases when force is applied to the inside of the tube fabric, the length is still long enough to interfere with the work activities of workers. There is a problem that hinders the operator's work convenience.

Accordingly, in order to improve the operator's work convenience, there is a need for a shock absorbing lanyard for an industrial safety swing capable of shortening the length of the shock absorbing lanyard and better absorbing the shock applied to the operator in case of a fall.

1 and 2, the shock absorbing lanyard 100 for an industrial safety swing according to the first embodiment of the present invention extends when an impact load is transmitted, and a poisa band 130 and an impact absorbing shock When the poisa band 130 is broken by the safety band 120 to prevent the operator from falling, the combination 110 is coupled to each other to be stacked, and one carabiner 150 to which one end of the assembly 110 is bound. ), and one hook 160 to which the other end of the assembly 110 is bound.

The industrial safety swing is worn on the worker's body and includes shoulder belts, chest belts, waist belts, and leg belts. And when the weight of the worker is applied in the event of a fall accident, the poisa band 130 constituting the assembly 110 is elongated to absorb the shock, and the safety band 120 is of the work material when the poisa band 130 is broken. Prevent falls.

On the other hand, one end of the assembly 110 is bound to the carabiner 150, and the carabiner 150 is fastened to a waist belt of an industrial safety swing or a swing hanger 170 disposed on the back of a worker. In addition, the other end of the assembly 110 is bound to the hook 160, and the hook 160 is fastened to a fixed support to prevent a fall accident of a worker that may occur during work. That is, in the event of a fall accident, the weight of the worker and the load increased by the acceleration thereof are transmitted to the assembly 110 through the hook 160, and when the impact load is transmitted to the assembly 110 due to a fall accident, the assembly 110 ) Mitigates the impact on the worker and prevents the worker from falling.

The combination body 110 according to the present embodiment includes a poisa band 130 woven into a tube fabric by a warp yarn 131 and a weft yarn first synthetic fiber 133, and a warp yarn second yarn 121 and It includes a safety band 120 that is woven into a tube fabric by a third synthetic fiber yarn 123 that is a weft and a rubber yarn 125 that is a warp yarn and is laminated to the fabric yarn band 130 and combined.

And the center of the poisa band 130 and the center of the safety band 120 are coupled to be laminated to each other by the rubber thread 125 constituting the safety band 120 to form a first corrugated part (C1) corrugated in the longitudinal direction. do.

The poisa band 130 is woven into a tube fabric using the warp yarn 131 and the first synthetic fiber yarn 133, which is a weft yarn, and is formed flat. POY (Partially Oriented Yarn, 131) can be elongated in the longitudinal direction when a large force is applied, and a strong impact applied to the worker as the tube fabric woven with the poi yarn 131 is stretched by the impact applied during a fall. Can alleviate and absorb.

When the impact load is transmitted by the fall accident, the poisa band 130 is primarily extended in the longitudinal direction of the rubber yarns 125 coupled with the safety band 120 to alleviate and absorb the impact applied to the worker, and 2 The rubber yarns 125 are cut off by the car and the fois yarns 131 are elongated in the longitudinal direction to alleviate and absorb the impact applied to the worker. Therefore, since the rubber yarns 125 and the poisers 131 firstly alleviate and absorb the strong impact applied to the worker during a fall accident, it is possible to prevent a strong impact from being directly applied to the worker.

In addition, the safety band 120 is woven into a tube fabric by the second chemical fiber yarn 121 that is warp, the third chemical fiber yarn 123 that is weft, and the rubber yarn 125 that is warp and tester.

The safety band 120 is stacked and coupled to the poisa band 130 and is formed longer than the total elongation of the poisa band 130, so that the worker falls when the poisa band 130 is broken by a strong impact. Prevent.

On the other hand, when the worker works in a state in which the shock absorbing lanyard 100 is connected to the industrial safety swing, if the length of the shock absorbing lanyard 100 is long, there is a problem that the workability of the worker is hindered and workability is deteriorated.

Accordingly, in this embodiment, the center of the safety band 120 and the center of the poisa band 130 are wrinkled in order to shorten the length of the assembly 110 before the impact load is applied in order to improve the operator's work convenience. To form. To this end, as described above, the center of the poisa band 130 and the center of the safety band 120 are combined to be laminated to each other using the rubber thread 125 forming the safety band 120, and the first wrinkle corrugated in the longitudinal direction. Form part (C1). That is, the center of the foisa band 130 and the center of the safety band 120 together form a first corrugated portion (C1).

The weaving state of the first corrugated portion C1 according to the present embodiment will be described with reference to FIGS. 3 and 4 as follows.

As shown in FIG. 3, the second chemical fiber yarn 121 is used as a warp, and a third chemical fiber 123 is used as the weft as the tube fabric forming the middle portion of the safety band 120. In addition, the rubber yarn 125 is disposed to be spaced apart between the inclined second chemical fiber yarns 121.

In the case of using 4 to 8 second chemical fiber yarns 121 arranged side by side as one first unit (S1) in this embodiment, the two rubber yarns 125 are repeated between the first unit bodies (S1). So they are arranged side by side. Preferably, the eight second chemical fiber yarns 121 are used as one first unit (S1), and the two rubber yarns 125 are repeatedly arranged side by side between the first units (S1). This is a first corrugation part when less than four second chemical fiber yarns 121 are used as one first unit (S1) and two rubber yarns 125 are repeatedly disposed between the first unit bodies (S1). The wrinkles of C1) are excessive, and two rubber yarns 125 are repeatedly disposed between the first unit bodies (S1) by using more than eight second chemical fiber yarns 121 as one first unit (S1). In this case, it is difficult to form the wrinkles of the first wrinkle part C1.

In addition, as described above, the center of the safety band 120 and the center of the poisa band 130 are coupled by the rubber thread 125 constituting the safety band 120 to form a first corrugated portion (C1).

As shown in FIG. 4, the two rubber yarns 125 are placed on the upper fabric U1 of the tube fabric forming the safety band 120 as warp and a plurality of third chemical fiber yarns 123 which are weft yarns continuously disposed. ), and then placed between the upper fabric (U1) and the lower fabric (D1) of the tube fabric forming the safety band 120 at a predetermined distance as an examination, and forming the poisa band 130 as a warp. After being woven into the lower side of the plurality of first chemical fiber yarns 133, which are weft yarns positioned in the lower fabric D2 of the tube fabric and continuously arranged, the upper fabric of the tube fabric forming the safety band 120 at a predetermined distance as an examination ( It is arranged between U1) and the lower fabric (D1).

The two rubber yarns 125 repeat the above-described operation so that the center of the safety band 120 and the center of the poisa band 130 are laminated to form a first corrugated part C1. That is, when the two rubber yarns 125 are woven with a plurality of third synthetic yarns 123 and a plurality of first synthetic yarns 133, they function as warp yarns, and a plurality of third synthetic yarns 123 and a plurality of first synthetic yarns (133) and if it is not woven, it functions as an examination.

Preferably, the two rubber yarns 125 are woven into the upper side of the 2 to 4 third synthetic fiber yarns 123, which are wefts located on the upper fabric (U1) of the safety band 120 as warp yarns, and are woven into the upper side of the weft yarns 123 as a judge. It is arranged side by side between the upper fabric (U1) and the lower fabric (D1) of the safety band 120 by a predetermined distance corresponding to the interval of the third chemical fiber yarn 123 of the dog, and the lower fabric of the poisa band 130 as a warp The upper part of the safety band 120 is woven into the lower side of the 2 to 4 first synthetic fiber yarns 133, which are the wefts located in (D2), and as a screening, a predetermined distance corresponding to the interval between the 8 third synthetic fiber yarns 123, which are the wefts, as an examination. It is arranged side by side between the fabric (U1) and the lower fabric (D1).

This has a problem in that it is difficult to form the first corrugated portion C1 when the two rubber yarns 125 are woven into the upper side of one third synthetic fiber yarn 123 as weft yarns or the lower side of the first synthetic fiber yarn 133. In addition, when the two rubber yarns 125 are woven into the upper side of the five or more third synthetic fiber yarns 123, which are weft yarns, or the lower side of the first synthetic fiber yarn 133, the rubber yarn 125 may enter the outside of the tube fabric. In this case, there may be a problem in that the rubber thread 125 may be broken due to friction with the outside.

And in this embodiment, in the case where the two rubber yarns 125 function as screening, the upper fabric (U1) and the lower part of the safety band 120 by a predetermined distance corresponding to the interval between the eight third synthetic fiber yarns 123, which are weft yarns, Although it is shown to be arranged side by side between the fabrics (D1), it is not limited thereto, and the two rubber yarns 125 are judged according to the height of the wrinkles between the upper fabric (U1) and the lower fabric (D1) of the safety band 120 It is possible to vary the predetermined distance arranged in parallel to.

On the other hand, the rubber yarn 125 is woven in a state elongated by 70 to 90% of the total elongation length.

In addition, since the length of the safety band 120 is formed longer than the total elongation of the poisa band 130, the center of the safety band 120 and the center of the poisa band 130 are mutually coupled to each other to form a first corrugated portion ( Even in the case of forming C1), the length from both sides of the center of the safety band 120 to the ends is longer than the length from both sides of the center of the poisa band 130 to the ends.

In this case, since it may interfere with the work activities of the worker and reduce workability, in this embodiment, in order to further improve the work convenience of the worker, the safety band 120 is a central portion (specifically, the first corrugated portion (C1)) A second corrugated part (C2) that extends from one side of and is made of a tube fabric and is corrugated in the longitudinal direction, and extends from the other side of the center (specifically, the first corrugation part (C1)) and is woven into a tube fabric, which is corrugated in the longitudinal direction. It further includes 3 wrinkles (C3).

In this embodiment, the lengths of the second and third corrugated portions C2 and C3 are such that the shock absorbing lanyard 100 does not sag in consideration of the working environment of the worker.

The weaving states of the second and third corrugations C2 and C3 according to the present embodiment will be described with reference to FIGS. 5 and 6.

The second corrugated part (C2) and the third corrugated part (C3) are formed to extend from both sides of the second corrugated part (C2), and are woven into a tube fabric. And in weaving the second wrinkle portion (C2) and the third wrinkle portion (C3), the rubber yarn 125 forming the first wrinkle portion (C1) is used. Meanwhile, since the second wrinkle portion C2 and the third wrinkle portion C3 are woven identically, the weaving state of the second wrinkle portion C2 will be described, and the weaving of the third wrinkle portion C3 will be omitted.

As shown in Figure 5, the tube fabric forming the second corrugated portion (C2) of the safety band 120 is a second synthetic fiber yarn 121 is used as a warp, and a third synthetic fiber yarn 123 is used as the weft. In addition, the rubber yarn 125 is disposed to be spaced apart between the inclined second chemical fiber yarns 121.

In this embodiment, in the case of using 4 to 8 second chemical fiber yarns 121 arranged side by side as one second unit (S2), one rubber yarn 125 is repeated between the second unit bodies (S2). So they are arranged side by side. Preferably, the eight second chemical fiber yarns 121 are used as one second unit (S2), and one rubber yarn 125 is repeatedly arranged side by side between the second units (S2).

This is a second corrugation part when less than four second chemical fiber yarns 121 are used as one second unit (S2) and one rubber yarn 125 is repeatedly disposed between the second unit bodies (S2). The wrinkles of C2) are excessive, and one rubber yarn 125 is repeatedly disposed between the second unit bodies (S2) by using more than eight second chemical fiber yarns 121 as one second unit (S2). In this case, it is difficult to form the folds of the second folds C2.

As shown in Fig. 6, one rubber yarn 125 is a plurality of third chemical fiber yarns 123 that are weft yarns that are positioned on the upper fabric (U1) of the tube fabric forming the safety band 120 as a warp and are continuously arranged. ), and then placed between the upper fabric (U1) and the lower fabric (D1) of the tube fabric forming the safety band 120 at a predetermined distance as an examination, and forming the safety band 120 as a warp After being woven into the lower side of a plurality of third synthetic fiber yarns 123, which are weft yarns positioned in the lower fabric D1 of the fabric and continuously arranged, the upper fabric of the tube fabric forming the safety band 120 at a predetermined distance as an examination (U1) ) And the lower fabric (D1).

One rubber thread 125 repeats the above-described operation to continuously form a second corrugated part C2 on one side of the first corrugated part C1. That is, when one rubber yarn 125 is woven with a plurality of third synthetic fiber yarns 123, it functions as a warp, and when it is not woven with a plurality of third synthetic fiber yarns 123, it functions as an examination.

Preferably, one rubber yarn 125 is woven into the upper side of the 2 to 4 third synthetic fiber yarns 123, which are two to four weft yarns located on the upper fabric U1 of the safety band 120 as a warp, and the weft yarn 19 It is arranged side by side between the upper fabric (U1) and the lower fabric (D1) of the safety band 120 by a predetermined distance corresponding to the interval of the third synthetic fiber (123), and as a warp, the lower fabric ( The upper fabric of the safety band 120 is woven into the lower side of the 2 to 4 third synthetic fiber yarns 123, which are wefts located in D1), and as a screening, a predetermined distance corresponding to the interval between the 19 third synthetic fiber yarns 123, which are wefts, It is arranged side by side between (U1) and the lower fabric (D1).

This has a problem in that it is difficult to form the second corrugated portion C2 when one rubber yarn 125 is woven into the upper side of one third synthetic fiber 123, which is a weft, or the lower side of the third synthetic fiber 123. In addition, when one rubber yarn 125 is woven into the upper side of five or more third synthetic fiber yarns 123, which are weft yarns, or the lower side of the third synthetic fiber yarn 123, the rubber yarn 125 may enter the outside of the tube fabric. In this case, there may be a problem in that the rubber thread 125 may be broken due to friction with the outside.

And in this embodiment, in the case where one rubber yarn 125 functions as an examination, the upper fabric (U1) and the lower part of the safety band 120 by a predetermined distance corresponding to the interval between the 19 third synthetic fiber yarns 123, which are weft yarns, It is shown to be arranged side by side between the fabrics (D1), but is not limited thereto, and one rubber yarn 125 is used as an examination according to the height of the wrinkles between the upper fabric (U1) and the lower fabric (D1) of the safety band 120 It is possible to vary the predetermined distance arranged in parallel to.

On the other hand, the rubber yarn 125 is woven in a state elongated by 70 to 90% of the total elongation length.

In addition, the safety band 120 according to the present embodiment extends from the second corrugated portion (C2) in order to be bound to the carabiner 150 and the other end to the hook 160 of the assembly 110 It further includes a first flat portion (F1) woven into a fabric and flat in the longitudinal direction, and a second flat portion (F2) extending from the third corrugated portion (C3) and woven into a tube fabric and flat in the longitudinal direction.

A carabiner ring H1 that is folded and sewn in a state in which the end of the first flat part F1 forming one end of the safety band 120 and the end of the one end of the poisa band 130 coincide with each other and bound to the carabiner 150 ), and the end of the second flat portion (F2) forming the other end of the safety band 120 and the other end of the poisa band 130 are folded and sewn in a state in which they coincide with each other. It forms a hook ring (H2) to be bound.

The weaving states of the first flat portion F1 and the second flat portion F2 according to the present embodiment will be described with reference to FIGS. 7 and 8.

The first flat portion F1 is formed to extend from the second corrugated portion C2 and is woven into a tube fabric. In addition, the second flat portion F2 is formed to extend from the third corrugated portion C3 and is woven into a tube fabric. Meanwhile, since the first flat portion F1 and the second flat portion F2 are woven in the same manner, the weaving state of the first flat portion F1 will be described, and the weaving of the second flat portion F2 will be omitted.

As shown in Figure 7, the tube fabric forming the first flat portion (F1) of the safety band 120 uses the second synthetic fiber yarn 121 as the warp, and the third synthetic fiber yarn 123 is used as the weft. As a rubber thread 125 is used.
