Description

{FULL BODY HARNESS WITH PROTECTIVE MEMBER}

The present invention (Disclosure) relates to a swing-type safety harness, which is a protective device worn by workers to prevent the risk of falling during high-altitude work.

This section provides background information related to the present disclosure which is not necessarily prior art.

In general, during the construction and maintenance of semiconductor production lines, most equipment or mobile lines are installed at high locations, so high-altitude work (over 2 m) frequently occurs.

For example, to prevent the risk of falling during high-altitude work, workers wear safety harnesses and perform high-altitude work while connecting the harnesses to safety ropes installed on the support using lanyards.

Meanwhile, the safety harnesses mentioned above include belt-type safety harnesses, upper body-type safety harnesses, and swing-type safety harnesses, and recently, swing-type safety harnesses that evenly distribute the load in the event of a fall are widely used.

However, the existing swing-type safety belt had the problem of exposing the worker's torso.

And because of the aforementioned problems, workers often get injured by hitting structures within their work area or by hitting tools used by neighboring workers.

The present invention (Disclosure) aims to provide a swing-type safety belt having a protective member that can protect a worker from collisions, etc. that occur during high-altitude work.

This section provides a general summary of the disclosure and is not a comprehensive disclosure of its full scope or all of its features.

In order to solve the above problem, a swing-type safety belt having a protective member according to one aspect among several aspects describing the present invention comprises: a safety belt having a waist band worn on a worker's waist, first and second shoulder bands worn on both shoulders of the worker, first and second leg bands worn on both thighs of the worker, and a safety loop to which a lanyard is connected; at least one first protective member mounted on an outer surface along the longitudinal direction and the width direction of the waist band, the first and second shoulder bands, and the first and second leg bands; and a second protective member mounted between the first and second shoulder bands so as to shield a portion of the worker's torso exposed between the first and second shoulder bands so as not to interfere with the movement of the worker's neck and both arms when the safety belt is worn, wherein the first protective members and the second protective members can protect the worker by blocking the colliding object by hardening when a physical collision occurs.

In a swing safety belt having a protective member according to one aspect of the present invention, the first protective member includes a strip formed in a tube shape of a soft material with a hollow interior and closed at both ends; and a first protective filler filled in the hollow interior of the strip; wherein the first protective filler may be provided as a viscoelastic material that hardens when pressure is instantaneously applied from the outside and softens when the pressure is removed.

In a swing-type safety belt having a protective member according to one aspect of the present invention, a fastener is installed on the outer surface of a waist band, first and second shoulder bands, and first and second leg bands so that the first protective member can be removably and elastically installed, and the fastener may be installed to have an “Ω” shape when viewed in a plan view and to be spaced apart from each other along the length direction of the waist band, the first and second shoulder bands, and the first and second leg bands.

In a swing safety belt having a protective member according to one aspect of the present invention, the first protective filler may be formed by mixing water and starch in a ratio of 1:2 to 3.

In a swing safety belt having a protective member according to one aspect of the present invention, the second protective member includes a screen having a grid-like mesh shape formed by warp and weft sections formed in a tube shape of a soft material having a hollow interior and closed at both ends; a second protective filler filled in the hollow interior of the warp and weft sections; and a border section closing the perimeter of the screen; wherein the second protective filler may be provided as a viscoelastic material that hardens when pressure is applied instantaneously from the outside and softens when the pressure is removed.

In a swing safety belt having a protective member according to one aspect of the present invention, the frame portion can be detachably attached to the first and second shoulder bands via a belt tape so that the screen shields between the first and second shoulder bands.

In a swing safety belt having a protective member according to one aspect of the present invention, the second protective filler may be formed by mixing water and starch in a ratio of 1:2 to 3.

According to the present invention, when a collision occurs between a protruding structure within a work area and a tool used by a neighboring worker during high-altitude work, the first and second protective fillers of the first and second protective members mounted on the safety belt instantly harden to block the structure and the tool, thereby preventing the worker's torso from being directly hit or stabbed, thereby providing a remarkable effect of preventing injury to the worker in advance due to collision between a protruding structure and a tool during high-altitude work.

Hereinafter, an embodiment of a swing-type safety belt having a protective member according to the present invention will be described in detail with reference to the drawings.

Figures 1 to 4 are schematic drawings showing a swing-type safety belt having a protective member according to the present invention.

Referring to FIGS. 1 to 4, a swing-type safety belt (100) having a protective member according to the present invention includes a safety belt (110), and first protective members (120) and second protective members (130) that are detachably installed on the safety belt (110).

First, the safety belt (110) is provided as a conventional swing-type safety belt with a structural configuration stipulated in the Industrial Safety and Health Act and the standard safety work guidelines for fall accident prevention.

The safety belt (110) includes a waist band (112) worn on the worker's waist, first and second shoulder bands (114a, 114b) worn on both shoulders of the worker, and first and second leg bands (116a, 116b) worn on both thighs of the worker.

Additionally, the safety belt (110) further includes a safety ring (118) having a roughly “D” shape to which a lanyard (not shown) is connected.

Here, the connection relationship between the waist band (112), the first and second shoulder bands (114a, 114b), the first and second leg bands (116a, 116b), and the safety ring (118) is a known technology, so a detailed description thereof is omitted.

In addition, the structure that allows the waist band (112), the first and second shoulder bands (114a, 114b), and the first and second leg bands (116a, 116b) to be worn or removed is a known technology, so a detailed description thereof is omitted.

The first protective member (120) and the second protective member (130) can protect workers from unexpected accidents that occur during high-altitude work, such as physical collisions.

Here, physical collision means collision with objects such as protruding structures within the work area and tools used by neighboring workers.

The first protective member (120) is mounted on the outer surface of the waist band (112), the first and second shoulder bands (114a, 114b), and the first and second leg bands (116a, 116b) in the longitudinal and width directions at least once.

Preferably, the first protective member (120) can be mounted in segments so as not to interfere with the length adjustment of the waist band (112), the first and second shoulder bands (114a, 114b), and the first and second leg bands (116a, 116b).

The first protective member (120) includes a strip (122) formed in a conventional tube shape with a hollow interior and closed ends as shown, and a first protective filler (124) filled in the hollow interior of the strip (122).

The strip (122) is provided by being made of a soft material, such as a common rubber or silicone resin, so as to prevent leakage of the first protective filler (124) filled inside while preventing interference when putting on and taking off the safety belt (110).

Although FIGS. 1 to 4 illustrate a strip (122) having a circular cross-section, the strip (122) may be formed to have a polygonal cross-section.

The first protective filler (124) is provided as a normal viscoelastic material that hardens when pressure is applied momentarily from the outside and softens when the pressure is removed.

In the present invention, the viscoelastic material provided as the first protective filler (124) is not particularly limited, but the first protective filler (124) may be formed by mixing ordinary water and starch that are harmless to the human body.

For example, the first protective filler (124) may be a mixture of water and starch in a ratio of 1:2 to 3, and the starch may be corn starch.

In addition, filling the first protective filler (124) into the strip (122) is a known technique, so a detailed description thereof is omitted.

For example, as a method of filling the first protective filler (124) into the strip (122), filling can be done using a conventional syringe or syringe, and after filling, the first protective filler (124) can be filled into the strip (122) by closing the penetration hole through which the tip of the syringe or syringe penetrates.

Meanwhile, the first protective member (120) is resiliently and detachably installed on the outer surface of the waist band (112), the first and second shoulder bands (114a, 114b), and the first and second leg bands (116a, 116b).

To this end, fasteners (126) having a shape roughly in the shape of the letter "Ω" when viewed in a plane are installed at predetermined intervals along the length direction of the waist band (112), the first and second shoulder bands (114a, 114b), and the first and second leg bands (116a, 116b).

The second protective member (130) is installed between the first and second shoulder bands (114a, 114b) so as to shield the exposed torso of the worker between the first and second shoulder bands (114a, 114b) when the safety belt (110) is worn, for example, the worker's chest and abdomen, both sides of the worker, and the worker's back.

For example, the second protective member (130) can be formed in a shape corresponding to the shape of the chest and abdomen, both sides of the worker, and the back of the worker exposed between the first and second shoulder bands (114a, 114b).

Preferably, the second protective member (130) can be mounted so as to shield the part of the worker's torso exposed between the first and second shoulder bands (114a, 114b) without interfering with the movement of the worker's neck and both arms.

The second protective member (130) includes a screen (132) formed by warp sections (134a) and warp sections (134b) formed in a conventional tube shape with a hollow interior and closed ends as shown, and a second protective filler (138) filled in the hollow interior of the warp sections (134a) and warp sections (134b).

The screen (132) has a grid-like mesh shape formed by the warp portions (134a) and the inclined portions (134b) as shown.

The slanted portions (134a) and inclined portions (134b) of the screen (132) are made of a soft material, such as a common rubber or silicone resin, so as not to interfere with the wearing and taking off of the safety belt (110) and to prevent the second protective filling material (138) filled inside from leaking, similar to the strips (122) of the first protective member (120).

And the screen (132) further includes a border portion (136) that closes the perimeter of the grid-shaped net formed by the warp portions (134a) and the slope portions (134b).

At this time, the border portion (136) is detachably attached using a conventional Velcro tape (not shown) so that the grid-shaped net formed by the warp portions (134a) and the slope portions (134b) can shield between the first and second shoulder bands (114a, 114b).

For example, a first fastener having a conventional Velcro hook formed on one side of the edge portion (136) may be attached, and a second fastener having a conventional Velcro loop formed so as not to interfere with the fasteners (126) may be attached to the outer surfaces of the first and second shoulder bands (114a, 114b).

Although the warp sections (134a) and the warp sections (134b) having circular cross sections are shown in FIGS. 1 to 4, the warp sections (134a) and the warp sections (134b) may be formed to have polygonal cross sections.

Here, the screen (132) is formed into a grid-shaped net using the warp sections (134a) and the inclined sections (134b) to allow ventilation and shield the exposed torso of the worker.

The second protective filler (138), like the first protective filler (124), is provided as a normal viscoelastic material that hardens when pressure is applied momentarily from the outside and softens when the pressure is removed.

In the present invention, the viscoelastic material provided as the second protective filler (138) is not particularly limited, but the second protective filler (138), like the first protective filler (124), can be formed by mixing ordinary water and starch that are harmless to the human body.

For example, the second protective filler (138) may be a mixture of water and starch in a ratio of 1:2 to 3, and the starch may be corn starch.

In addition, filling the second protective filler (138) into the warp portions (134a) and the inclined portions (134b) is a known technique, so a detailed description thereof is omitted.

For example, the method of filling the second protective filler (138) into the warp portions (134a) and the inclined portions (134b) may be the same as the method of filling the first protective filler (124) into the screed (122).

Here, the first protective members (120) and the second protective members (130) may be mounted on the safety belt (110) after the safety belt (110) is worn, or may be mounted on the safety belt (110) in advance before the safety belt (110) is worn.

In the case where a swing-type safety belt (100) having a protective member according to the present invention formed in this manner collides with a protruding structure within a work area or a tool used by a neighboring worker during high-altitude work, the first and second protective fillers (124, 138) of the first and second protective members (120, 130) mounted on the safety belt (110) instantly harden to block the structure and tool, thereby preventing the worker's torso from being directly hit or stabbed.

This prevents injuries to workers caused by collisions with objects such as protruding structures and tools during high-altitude work.

The intrinsic technical idea of the present invention is not limited in its possible implementation by the embodiments described above, and encompasses a range that can be easily proposed by a person skilled in the art through a method of substitution or change.

In addition, the terms used in the description of the present invention have been selected for the convenience of explanation, and therefore, in understanding the intrinsic technical idea of the present invention, they should be appropriately interpreted in a meaning that is consistent with the technical idea of the present invention, without being limited to the dictionary meaning.
