Description

Safety scaffolding The present invention relates to trestle scaffolding. More specifically, the present invention relates to safety trestle scaffolding. Generally, trestle scaffolding is provided in a form where the tops of two ladders are connected by platforms, and it is primarily used for interior finishing, wallpapering, and electrical wiring work at construction sites. Meanwhile, handrails are assembled on the tops of the platforms to prevent workers from falling, but assembling handrails is a very cumbersome task. FIG. 1 is a perspective view of a safety scaffolding according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of a safety scaffolding according to an embodiment of the present invention. FIG. 3 is a drawing showing a folded first handrail assembly (second handrail assembly). FIG. 4 is a drawing showing the unfolded first handrail assembly (second handrail assembly). Figure 5 is a drawing showing a latch fastened to a projection. The technical terms used herein are for the reference of specific embodiments only and are not intended to limit the invention. The singular forms used herein include plural forms unless phrases clearly indicate otherwise. The meaning of "comprising" as used in the specification specifies a particular characteristic, area, integer, step, action, element, and/or component, and does not exclude the presence or addition of other particular characteristic, area, integer, step, action, element, component, and/or group. Unless otherwise defined, all terms used herein, including technical and scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms defined in commonly used dictionaries are further interpreted to have meanings consistent with relevant technical literature and the present disclosure, and are not interpreted in an ideal or highly formal sense unless otherwise defined. For example, the term "applied" described below is interpreted to include both the state of being appropriately used and the state prior to being appropriately used. Expressions described in the singular in this specification may be interpreted as singular or plural unless explicit expressions such as "one" or "single" are used. In this specification, terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but said components are not limited by said terms. Such terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present disclosure, the first component may be named the second component, and similarly, the second component may be named the first component. In the flowchart described with reference to the drawings in this specification, the order of operations may be changed, several operations may be merged or some operations may be divided, and certain operations may not be performed. Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement the invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. FIG. 1 is a perspective view of a safety scaffold (100) according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the safety scaffold (100). As shown in FIG. 1 and FIG. 2, the safety scaffold (100) includes a step (110), a first ladder (120), a second ladder (130), a first handrail assembly (140), a second handrail assembly (150), and a control unit (160). Additionally, the safety scaffold (100) may include a first flame-retardant fabric (171), a second flame-retardant fabric (172), a first safety rope (181), and a second safety rope (182). The step (110) has a predetermined area. The step (110) may be rectangular when viewed from above. It is preferable that the width of the step (110) be 40 cm or more. The step (110) may be made of aluminum. The first ladder (120) is provided on the lower side of one end of the footrest (110) in the longitudinal direction. The first ladder (120) is provided to be foldable toward the center of the footrest (110). For the stability of the footrest (110), when the first ladder (120) is in an unfolded state, the angle between the footrest (110) and the first ladder (120) may be obtuse. The first ladder (120) may be provided in aluminum material. The first ladder (120) may be provided to be adjustable in length. The second ladder (130) is provided on the lower side of the other end of the footrest (110) in the longitudinal direction. The second ladder (130) is provided to be foldable toward the center of the footrest (110). The second ladder (130) is provided with the same specifications as the first ladder (120) to form symmetry. For the stability of the footrest (110), when the second ladder (130) is unfolded,
