Description

Technology Field

[0001] The present invention relates to a simple safety belt, and more specifically, to a simple safety belt that is mounted on a cut portion of a handrail to prevent safety accidents. Background Technology

[0003] While performing maintenance work on-site, workers often face situations where they must cut existing handrails or safety railings.

[0004] Such cutting operations inevitably occur under various working conditions, such as pipe replacement, maintenance, and structural changes.

[0005] However, after the handrail is severed, the work environment temporarily becomes an open space, significantly increasing the risk of safety accidents such as falls.

[0006] These risks become more severe when workers work at high places or must use equipment in confined spaces.

[0007] Under current work methods, it is often difficult to immediately weld or install replacement structures after cutting handrails, which frequently leads to problems where it is difficult to ensure safety during work.

[0008] Existing safety devices have disadvantages such as requiring a significant amount of time for installation and dismantling, or being heavy, which reduces worker mobility and work efficiency.

[0009] In addition, some devices can only be used under specific operating conditions, resulting in poor versatility and often being unsuitable for various work environments.

[0010] These limitations increase the safety burden on not only workers but also supervisors, and hinder the overall efficiency of on-site operations.

[0011] Therefore, there is an increasing need for lightweight safety devices that effectively reduce potential risks in the work environment and are easy to install. Prior art literature

FIG. 5 is a cross-sectional view showing the state in which an embodiment of the present invention is mounted on the cut portion of the handrail.

[0027] As illustrated in these drawings, according to one embodiment of the present invention, a simple safety device (100) mounted on a cut portion of a handrail comprises: a central body portion (101); a first variable length arm portion (103) which is coupled to a length that is drawn out from one side of the central body portion (101) and is inserted into a first handrail pipe portion (401) which is one side of the remaining handrail after the cut; and a second variable length arm portion (105) which is coupled to a length that is drawn out from the other side of the central body portion (101) and is inserted into a second handrail pipe portion (403) which is the other side of the remaining handrail after the cut.

[0028] Below, each component is described in detail.

[0029] central body part (101)

[0030] The central body (101) may be provided in a cylindrical shape with both sides open, for example.

[0031] The central body portion (101) may include a catch (501, 107) protruding inwardly in the radial direction at both ends.

[0032] The function of the stopper (501,107) will be described later.

[0033] The central body part (101) may have a structure in which an anti-slip part (not shown) is further provided on the outer surface.

[0034] The anti-slip portion may be provided, for example, in a structure formed of rubber material that wraps around the outer surface of the central body portion (101).

[0035] Additionally, the anti-slip portion may be provided by knurling the outer surface of the central body portion (101).

[0047] A stopper (303) formed at one end of the first-second arm (103b) serves to limit the pull-out length of the first-second arm (103b) by allowing the first-second arm (103b) to be pulled out only until it comes into contact with the stopper (503) of the first-second arm (103a) when the first-second arm (103b) is pulled out from the first-first arm (103a).

[0049] Second variable length arm (105)

[0050] The second variable length arm (105) is coupled such that the length drawn out from the other side of the central body (107) varies.

[0051] The second variable length arm (105) is inserted into the second handrail pipe section (403), which is the other side of the remaining handrail after the end is cut.

[0052] The second variable length arm (105) can be configured such that, for example, a plurality of pipes are combined in a telescopic manner to allow for variable length.

[0053] For example, the second variable length arm (105) may include a second-1 arm (105a) with one side inserted into the other side of the central body (107); and a second-2 arm (105b) with one side inserted into the other side of the second-1 arm (105a).

[0054] The second-1 arm (105a) may include a catch (305) protruding outwardly in the radial direction at one end.

[0055] A stopper (305) formed at one end of the second-1 arm (105a) serves to limit the pull-out length of the second-1 arm (105a) by allowing the second-1 arm (105a) to be pulled out only until it comes into contact with the stopper (107) of the central body part (101) when the second-1 arm (105a) is pulled out from the central body part (101).

[0056] The second-1 arm (105a) may include a catch (307) protruding inwardly in the radial direction at the other end.

[0057] One side of the 2-2 arm (105b) is inserted into the other side of the 2-1 arm (105a).

[0058] The second-2 arm (105b) may include a catch (309) protruding outwardly in the radial direction at one end.

[0059] A stopper (309) formed at one end of the second-2 arm (105b) serves to limit the pull-out length of the second-2 arm (105b) by allowing the second-2 arm (105b) to be pulled out only until it comes into contact with the stopper (307) of the second-1 arm (105a) when the second-2 arm (105b) is pulled out from the second-1 arm (105a).

[0061] Meanwhile, a simple safety belt (100) according to one embodiment of the present invention may further include a first anti-detachment member (109) that is detachably coupled to the end of the first variable length arm (103) exposed to the outside of the first handrail pipe section (401) so as to prevent the first variable length arm (103) inserted into the first handrail pipe section (401) from detaching.

[0062] For example, the first anti-detachment member (109) may have screw threads formed on its inner surface, and the screw threads formed on the inner surface of the first anti-detachment member (109) may be screw-coupled with the screw threads formed on the outer surface of the end of the first variable length arm (103) (more specifically, the first-2 arm (103b)).
