Description

{A SAFETY HOOK DEVICE}

The present invention relates to a safety hook hanging device, and more specifically, to a safety hook hanging device that is fastened to a horizontal member or a vertical member constituting a system scaffolding installed at a work site, and allows a worker to pass through an area where the horizontal member and the vertical member intersect while fastening a safety harness and proceeding in the direction of work, without unfastening the safety harness each time, thereby increasing the worker's work efficiency and preventing safety accidents such as falls in advance.

It is known that about half of the fatal accidents that occur at construction sites are due to falls, and the sites where falls can occur are diverse, including construction, civil engineering, large-scale facilities, shipyards, utility poles, and building cleaning. High-altitude work that carries the risk of falls is often temporary work, and the level of risk is constantly changing. Depending on the work location or nature of the work, it is often difficult to install separate railings, etc., or safety measures are often inadequate for other reasons. In addition, carelessness on the part of workers is one of the factors that causes falls.

In relation to this, in accordance with the rules on industrial safety and health standards based on Article 35 of the Industrial Safety and Health Act, in cases where there is a risk of falling due to difficulties in using work platforms or other fall protection measures during high-altitude work, workers must wear safety harnesses, and safety harness hook attachment equipment must be installed so that workers wearing safety harnesses can safely hang the harness hook.

In addition, the regulations require workers to be provided with, wear, and use safety harnesses in places where the working height or depth is 2 meters or more, and to wear and use safety harnesses in places such as aerial work platforms, scaffolding, hanging scaffolding, steel structure construction passageways, elevators, lifts, cranes, gondolas, rail vehicles, bridges, and confined spaces.

These regulations impose certain obligations not only on workers but also on employers. For example, employers must instruct work supervisors to monitor the wearing of safety belts and other protective equipment during work, and take necessary measures to prevent hazards, such as checking whether workers have attached the safety belt hook to the safety belt hook attachment device installed on the work surface.

Meanwhile, existing safety belts are largely divided into belt type and safety harness type. A belt type safety belt is a safety belt that has a belt-shaped part worn around the waist to support the body, while a safety harness type safety belt is a safety belt that has a belt-shaped part worn in an X shape around the arms, legs, and torso to support the body.

Both belt-type safety harnesses and harness-type safety harnesses have a rope-shaped part called a roop, which is used to connect the harness hook to a lifeline, structure, or other attachment device. The end of the lanyard has a metal hook-shaped part, and the hook is a part that opens and closes from the outside to the inside so that the lanyard can be attached to and removed from attachment devices.

A single-hook safety harness has a lanyard that is fixedly connected to a D-ring attached to the harness. A U-shaped safety harness has hooks on each end of the lanyard, so that when the worker is working, he or she connects one hook of the lanyard to the D-ring attached to the harness and the other hook of the lanyard to the harness attachment device, and when moving before and after work, he or she moves with both hooks of the lanyard connected to the D-ring attached to the harness.

However, a grid-shaped system scaffolding (steel structure) is installed on the outer surface of the work object, and this system scaffolding is installed so that the horizontal and vertical members intersect each other at intervals of approximately 2 meters. The worker moves while working by fastening a safety hook to the horizontal members of this system scaffolding, but there is an inconvenience in that the worker has to unfasten the safety hook one by one at the intersection area that exists every 2 meters, pass the intersection area, and fasten the safety hook again. As a result, there is a problem that workers frequently fall while working without fastening the safety hook due to this inconvenience.

The present invention has been made to solve the above problems, and the purpose of the present invention is to provide a safety hook hanging device that allows a worker to perform work by fastening a safety harness to a horizontal member or a vertical member constituting a system scaffolding installed at a work site, and to pass through an area where the horizontal member and the vertical member intersect when moving in the direction of work, thereby increasing the work efficiency of the worker by allowing the worker to pass without having to unfasten the safety harness each time.

In addition, the purpose of the present invention is to provide a safety hook hanging device that can prevent safety accidents, such as falls, from occurring while working without fastening the safety belt due to the inconvenience of fastening and releasing the safety belt every time a worker passes an intersection of horizontal and vertical members of a system scaffold, as has been the case in the past.

The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

According to one embodiment of the present invention for solving the above technical problem, a safety hook hanging device may include a sliding member that can be fastened to a horizontal member or a vertical member constituting a system scaffolding, and has a plurality of receiving grooves formed to receive the horizontal member or the vertical member; and a fastening member that is fastened to an outer end of the sliding member and has a ring formed on at least a portion of an outer surface to which a safety hook is fastened.

In addition, the horizontal member or the vertical member can be received in the receiving groove by rotating the sliding member at the intersection area of the horizontal member and the vertical member.

Additionally, the sliding member may be implemented as a pair of sliding members spaced apart from each other at a certain distance.

Additionally, the safety hook hanging device may further include a central axis configured to mutually couple the pair of sliding members.

In addition, the sliding member may be formed in a disc shape, and the inner surface of the fastening member may be formed with a curvature corresponding to the upper portion of the sliding member.

In addition, both ends of the sliding member may be formed in an 'ㄱ' shape facing outward, and the fastening member may be formed in a 'ㄷ' shape to accommodate both upper ends of the sliding member.

Additionally, the fastening member can be configured to fasten at an angle of 90° to 120° to the outer end of the sliding member.

In addition, the fastening member may further include a roller configured to reduce friction occurring between the horizontal member or the vertical member and the fastening member when the safety hook hanging device slides along the horizontal member or the vertical member.

Additionally, with respect to the height of the binding member, the area where the roller is implemented may correspond to the area where the ring is implemented on the outer surface of the binding member.

According to a safety hook hanging device according to one embodiment of the present invention, the convenience of work can be improved because the worker does not have to repeatedly tie and fasten the hook of the safety belt every time he or she reaches the intersection point of the horizontal member and the vertical member of the system ladder as in the past.

In addition, as mentioned above, there are frequent cases where workers do not attach safety belts to the system ladder due to inconvenience, and thus accidents in which workers fall due to carelessness and are injured or killed can be prevented in advance.

In addition, it is easy to use because it can easily pass through the point where the horizontal and vertical members of the system ladder intersect, and this can improve the work efficiency of the worker.

In addition, since it can be manufactured with a relatively simple configuration, the manufacturing cost is low and it is economical, and as a result, it can be easily applied in work situations, which can increase usability.

These terms are only intended to distinguish the components from other components, and the nature, order, or sequence of the components is not limited by the terms.

FIG. 1 is a perspective view showing a safety hook hanging device (100) according to one embodiment of the present invention, FIG. 2 is a back perspective view of FIG. 1, FIG. 3 is an exploded perspective view of a safety hook hanging device (100) according to one embodiment of the present invention, FIG. 4 is a cross-sectional view taken along line A-A of FIG. 1, and FIG. 5 is a drawing for explaining a binding range of a binding member (120) when the binding member (120) is bound to a sliding member (110) among the components of a safety hook hanging device (100) according to one embodiment of the present invention.

Referring to FIGS. 1 to 5, a safety hook hanging device (100) according to one embodiment of the present invention is composed of a sliding member (110) and a fastening member (120) fastened to an outer end of the sliding member (110), and can be fastened to a horizontal member (210, see FIG. 6) or a vertical member (220, see FIG. 6) constituting a system ladder.

For reference, the safety hook hanging device (100) according to one embodiment of the present invention is installed on one of the horizontal members (210) and the vertical members (220) constituting the system scaffolding, and thus has the advantage of being able to be utilized both in cases where a worker moves horizontally (i.e., left and right) and in cases where a worker moves vertically (i.e., up and down). However, in the following specification, for the convenience of explanation, the safety hook hanging device (100) according to one embodiment of the present invention will be described as being used by being tied to the horizontal member (210).

A safety hook hanging device (100) according to one embodiment of the present invention may include a sliding member (110) having a plurality of receiving grooves (111) formed to receive a horizontal member (210) or a vertical member (220). As shown in the drawing, the sliding member (110) may be formed in a disc shape, may have a plurality of wings formed between the plurality of receiving grooves (111), and may be configured as a pair arranged vertically.

In addition, as illustrated in the drawing, the sliding member (110) according to one embodiment of the present invention may be formed radially by the receiving grooves (111). Here, the receiving grooves (111) may be formed in a U-shape or a V-shape and configured such that their widths gradually narrow as they progress from the outside of the sliding member (110) toward the central axis (112), and the width of each receiving groove (111) may be implemented to be larger than the average cross-sectional area of the vertical member (220) so as to stably receive the vertical member (220).

The shape of the receiving groove (111) is such that the outer width of the receiving groove (111) must be wide so that the vertical member (220) can be more smoothly introduced into the receiving groove (111) and at the same time be more easily received into the inner side of the receiving groove (111).

In addition, as illustrated in the drawing, the sliding member (110) according to one embodiment of the present invention may be configured to have three receiving grooves (111). It is of course possible to have four or more receiving grooves (111), but when the fastening member (120) described later is coupled to the sliding member (110), the center of gravity may not be aligned, causing the member to lean to one side, or the fastening range of the fastening member (120) to the sliding member (110) may become narrow, thereby hindering the stability of the coupling. Accordingly, the inventors of the present invention have confirmed through various experiments and tests that the coupling stability is the best when the sliding member (110) is provided with three receiving grooves (111), that is, when it is configured with three wings.

In addition, a central axis (112) is coupled to the inner side of a pair of sliding members (110) spaced apart from each other at a predetermined distance, so that the pair of sliding members (110) can be arranged parallel to each other at a predetermined interval by the central axis (112). That is, the central axis (112) can be configured to couple the pair of sliding members (110) to each other.

In addition, the distance between the outer side of the sliding member (110) and the central axis (112) can be formed to be larger or slightly larger than the average diameter of the transverse member (210), so that the outer surface of the transverse member (210) can smoothly slide along the receiving groove (111).

Additionally, a safety hook hanging device (100) according to one embodiment of the present invention may include a fastening member (120) that is coupled to an outer end of a sliding member (110) and has a ring (121) formed on at least a portion of the outer surface to which a safety hook is fastened.

Here, the ring (121) may not be provided in the center of the fastening member (120), but may be provided offset to one side of the fastening member (120). Generally, in construction sites, etc., the horizontal member (210) is installed at a position lower than the worker's waist, and therefore, when the safety belt is fastened to the ring (121) of the safety hook hanging device (100) according to the present invention, a force is applied to pull the safety hook hanging device (100) in an upwardly inclined direction. Considering this point, the ring (121) of the safety hook hanging device (100) according to one embodiment of the present invention may be implemented on the upper side of the outer surface of the fastening member (120), and a predetermined direction indicator (not shown) may be displayed so that the safety hook hanging device (100) can be mounted on the horizontal member (210) in a direction in which the ring (121) is placed on the upper side.

In addition, the inner surface of the binding member (120) can be formed with a curvature substantially corresponding to the upper end of the sliding member (110), whereby the binding member (120) can continuously slide along the outer (i.e., edge) end of the sliding member (110). In other words, the sliding member (110) acts as a kind of guide, and the binding member (120) can move in a bound state by being guided by the outer end of the sliding member (110).

In order to maintain a continuous bonding state of the sliding member (110) and the bonding member (120), as illustrated in FIG. 4, both ends of the sliding member (110) may be formed in an 'ㄱ' shape facing outward, and the bonding member (120) may be formed in a 'ㄷ' shape to accommodate both upper ends of the sliding member (110). For reference, the drawing illustrates that both ends of the sliding member (110) are formed in an 'ㄱ' shape facing outward, and the bonding member (120) is formed in a 'ㄷ' shape to accommodate both upper ends of the sliding member (110); however, according to another embodiment of the present invention, the shapes of the sliding member (110) and the bonding member (120) may be formed in opposite directions and bonded.

In addition, in addition to the shape shown in the drawing, various fastening means may be additionally or alternatively applied so that the fastening member (120) can be moved on the outer end of the sliding member (110) while the sliding member (110) and the fastening member (120) are fastened.

In addition, when the safety hook hanging device (100) is moved by being fastened to the horizontal member (210), friction occurs between the horizontal member (210) and the fastening member (120), and this friction can be a major cause of hindering the movement of the worker. To solve this problem, the safety hook hanging device (100) according to one embodiment of the present invention can additionally be fastened with a roller (122) to the fastening member (120) so as to realize smoother movement when sliding along the outer surface of the horizontal member (210).

In addition, when the fastening member (110) is rotated at the intersection area of the horizontal member (210) and the vertical member (220), a roller (122) may be applied to ensure smooth passage when the horizontal member or the vertical member is accommodated in the adjacent receiving groove (111). The roller (122) may be provided alone on one side of the fastening member (120) or as a pair on both sides of the fastening member (120), and when the safety hook hanging device (100) slides along the outer surface of the horizontal member (210) through the roller (122), smooth movement may be improved. The roller (122) may be implemented for the substantially entire height of the fastening member (120), or may be implemented for only a portion of the height of the fastening member (120) as illustrated in the drawing. In the latter case, the area where the roller (122) is implemented with respect to the height of the binding member (120) may substantially correspond to the area where the ring (121) is implemented with respect to the height of the binding member (120).

Meanwhile, as illustrated in FIG. 5, the fastening member (120) may be fastened within a range of 90° to 120° to the outer end of the sliding member (110). If the fastening member (120) is fastened at an angle greater than 120° to the outer end of the sliding member (110), the sliding member (110) may not rotate easily when the worker passes over the vertical member (220) while moving, which may cause inconvenience in the work. In addition, if the fastening member (120) is fastened at an angle less than 90° to the outer end of the sliding member (110), the sliding member (110) may rotate when the worker passes over the vertical member (220) while moving, and the fastening may be released by the receiving groove (111), which may cause danger to the worker. Therefore, this problem can be prevented by preferably implementing the fastening member (120) to be fastened in a range greater than 90° and less than 120° with respect to the outer end of the sliding member (110).

Hereinafter, the usage state of the safety hook hanging device (10) according to one embodiment of the present invention configured as described above will be described in more detail.

FIGS. 6 to 10 are drawings showing the state of use of a safety hook hanging device (100) according to one embodiment of the present invention, sequentially showing the process in which the safety hook hanging device (100) is fastened to a scaffolding system and passes through an area where a horizontal member (210) and a vertical member (220) intersect, and FIG. 11 is a drawing showing an example of a worker fastening a safety hook hanging device (100) according to one embodiment of the present invention to a system scaffolding, for example, to a horizontal member (210).

First, the worker can insert the inner side of the sliding member (110) into the horizontal member (210) and then fasten the fastening member (120) to the outer end of the sliding member (110). Then, the hook of the safety harness that is pulled out and fastened to the belt or safety harness worn on the worker's body can be fastened to the ring (121) of the fastening member (120). That is, as exemplarily illustrated in FIG. 11, the safety harness can be stably fastened to the system scaffolding through the safety hook hanging device (100) according to one embodiment of the present invention.

As shown in FIGS. 6 and 7, as a worker moves in the direction of work progress, for example, as he moves horizontally left and right at a construction site, the safety hook hanging device (100) can also move along the horizontal member (210).

When vertical members (220) are joined at regular intervals, for example, approximately every 2 meters, and the sliding member (110) passes through the vertical member (220), as shown in FIG. 8, the sliding member (110) can rotate in one direction along the groove formed in the fastening member (120), and at this time, the vertical member (220) can be received into the inner side of the receiving groove (111).

Thereafter, the safety hook hanging device (100) that has passed through the vertical member (220) can slide along the horizontal member (210) to the next working location along the direction of the worker's work progress, as shown in FIGS. 9 and 10, and at this time, as described above, the mobility is further improved by the roller (122) provided in the fastening member (120).

In addition, although not explicitly shown in the drawing, according to an additional embodiment of the present invention, a special paint (fluorescent treatment, etc.) may be applied to the outer surface of the sliding member (110) or the surface of the fastening member (120), thereby allowing the worker to check from a distance whether the safety hook hanging device (100) is fastened to the system scaffolding and working. For example, if the safety hook hanging device (100) according to one embodiment of the present invention is not fastened to the system scaffolding, the worker's movement and working are not possible, thereby further enhancing worker safety at construction sites, etc.

As described above, according to the safety hook hanging device according to one embodiment of the present invention, the convenience of work can be improved because the worker does not have to repeatedly tie and fasten the safety belt hook every time he or she reaches the intersection point of the horizontal member and the vertical member of the system ladder as in the past.

In addition, as mentioned above, there are frequent cases where workers do not attach safety belts to the system ladder due to inconvenience, and thus accidents in which workers fall due to carelessness and are injured or killed can be prevented in advance.

In addition, it is easy to use because it can easily pass through the point where the horizontal and vertical members of the system ladder intersect, and this can improve the work efficiency of the worker.

In addition, since it can be manufactured with a relatively simple configuration, the manufacturing cost is low and it is economical, and as a result, it can be easily applied in work situations, which can increase usability.

As described above, the best embodiment has been disclosed in the drawings and the specification. Although specific terms have been used herein, they have been used only for the purpose of describing the present invention and have not been used to limit the meaning or the scope of the present invention described in the claims. Therefore, those skilled in the art will understand that various modifications and equivalent other embodiments are possible from this. Therefore, the true technical protection scope of the present invention should be determined by the technical idea of the appended claims.
