The present invention relates to a ladder-shaped simple work bench.

The present invention has been developed a technology that reinforces the function of the safe workbench while utilizing the advantages of the ladder ladder is difficult to use because of the high risk of falling the conventional ladder.

 In the present invention, the conventional work bench for assembling has a vertical member, a horizontal member, a brace member, and a scaffold as a main member, and has an advantage of great expandability, and is used regardless of a high place, a high place or a high place. However, it is difficult to install the conventional workbench in a place where the space is small, such as between a machine and a building wall, between a machine and a machine, or inside a machine. Ladders are often used in such narrow spaces, where the ladder itself may slide or the worker may fall on the ladder. Therefore, in the present invention, the working range is not so large, and it was intended to develop a ladder-type simple workbench that does not slip or fall while occupying the same volume as the ladder, but does not slip or fall.

  In the present invention, the footing and the railings are integrated in the conventional ladder and the two ladders face each other, and the footing and the railing are horizontally connected to each other to make a workbench, and easy to assemble, vertical, horizontal, brace and footings. The members constituting the two parts are integrated without being divided into each other, so that they are easy to move and structurally strong.

As a result of the present invention, it is possible to use a safe and easy work place where the conventional ladder was used, thereby further preventing industrial accidents and worker safety.

Before the present invention, terms related to the present invention will be described. The present invention has been invented with the basic concept of building a work platform that prevents the fall, and the ladder is prevented from falling, and the worker is working in the middle of the two ladders by connecting two ladders to the scaffold and the scaffolding on the ladder Attached is called "ladder assembly", and the ladder assembly is paired to connect the scaffold, railing, and brace, and the ladder assembly section on the bottom layer is called "single work bench", and the upper part is "single work" Name the number of floors corresponding to the number of floors, such as the "three-stage work body", and the work piece is integrated together, such as the one-stage work, the two-stage work, and the three-stage work. ”

  The present invention is to use the ladder 11, the handle 12, the scaffolding 13, the handrail 14, the inclined column 15 and the brace 16 as a main component to make a safe workbench Technology. Conventional ladders use two H-shaped ladders leaning against each other in A-shape, and one ladder is used against the wall, but there is a high risk of an accident that the ladder slips or a person falls on the ladder.

Therefore, the present invention is a technology that can be used by assembling a safe workbench as soon as a pair of ladders, handrails, braces are integrated into the ladder.

  The ladder used in the present invention is not different from the conventional ladder form. However, since the footrest, railing, and braces are assembled to the handle 12 of the ladder, the structure must be stronger than before.

The term "ladder assembly" is only used to facilitate the practice of the present invention. "Ladder assembly" means that the brace, the balustrade, the scaffolding, the inclined column is integrated with the ladder according to the present invention is easy to move, easy to assemble. Therefore, in order to build a work platform according to the present invention, a pair (two) ladder assemblies are required.

  Easy assembly means adopting wedge bolt type fastening means

A ladder assembly construction step comprising the pillars 11, the handles 12, the scaffolds 13, the handrails 14, the inclination supports 15, and the braces 16 as main components;

Steps to face the two ladder assemblies in a pair, the scaffolding, the railing is positioned horizontally, inclined the brace, inclined the inclined holding out the first stage work platform (10) building step

It is the same as the construction method of the ladder workbench of the first workbench, but the two-stage ladder assembly slides out of the first workbench assembly and stops at the upper stator of the first workbench.

It is the same as the ladder workbench construction method of the two-stage workbench, but the three-stage ladder assembly slides out of the two-stage ladder assembly and stops at the upper stator of the two-stage workbench, and the three-stage workbench 20 is connected to the three-stage workbench;

Ladder characterized in that the step of constructing an extension scaffold 40 installed out of the work platform, the expansion support 50 for supporting the extension scaffold at any height of the first or second stage work platform or the three-stage work bench It relates to a method of assembling a type easy bench and a ladder type simple platform.

When described in detail so that the invention can be carried out as follows.

Easy assembling means adopting the wedge bolt type fastening means is a wedge type fastening means that can be simply fastened with a hammer and the wedge type alone is a fastening mechanism that adds a bolt fastening method for complete and solid assembly when there is doubt about the fastening force of the assembly. Apply a commercially available fastening mechanism, but the application of the clamp (CP) is shown in Figure 1 the temporary date. The simplest wedge bolt type fastening means is a fastening mechanism registered with a block scaffolding trademark, and the clamp (CP) illustrated in FIG. 6 is placed on the handle and hit with a hammer to the end of the clamp (CP) in a V shape. The V-shaped inner surface presses the handle while being engaged. However, in order to fix it more securely, the bolt nut shown in the drawing may be tightened like a steel pipe clamp. This clamp CP is a combination of a steel pipe clamp and a wedge-shaped fastening mechanism.

  In the present invention, the hinge (Hinge, HD) also rotates during the assembly / disassembly operation, but should be equipped with a stopper for stopping the rotation of the hinge because the assembly should have a solid fastening structure. The stopper is not illustrated in the drawings of the present invention, but can be easily implemented by using a screw threaded to the hinge and tightened as a bolt.

The ladder assembly having the pillars 11, the handles 12, the scaffolds 13, the handrails 14, the inclined column 15, and the braces 16 as main components is performed as follows.

  The members constituting the pair of ladder assemblies include a ladder such as (1) of [2] and two (11) consisting of two pillars 11 and a plurality of handles as shown in (1) of [3]. B) a main material such as an angle or a pipe as shown in Fig. 3, and a railing mainly composed of an angle or a pipe as shown in (3) of Fig. 3, and a conventional footrest as shown in Fig. 3 (4). It consists of scaffolds with different parts. It is added to the inclined column 15 to prevent the assembly from falling when the ladder is assembled in the form of a safe workbench.

The pillar 11 constituting the ladder assembly is a roller rail (RL) as shown in (1) of the conventional ladder pillar, where the roller 1 (R1) and roller 2 (R2) is the lower column Is laid on. The pillar 11 has a fastening means for fastening means to the upper and lower portions of the adjacent pillar by having a fastening means overlapping the ladder part and the ladder up and down overlapping (HT). The method of providing an overlapping fastening part is easily described by applying the principles of the fastener 1 and the fastener 2 for connecting different members at the connection point CT, and thus, the description will not be further provided. For rapid assembly, a triangular wedge can be installed on the top of the column of the first stage to support the bottom of the column of the second stage.

(CP, Clamp) is provided. (1) of FIG. 8 is a front view of the scaffold 13, (2) is a top view of the scaffold, and (3) of FIG. 8 is the handrail 14 and the brace 16 of FIG. Top view. In the case of handrails and braces, the one hinged end of the footboard according to the present invention is the same in plan but the width thereof is different only from the same as the angle width or pipe diameter.

The clamp is usually made by applying a steel pipe clamp, and thus will not be described in further detail. The footrest 13 includes a hinge HD, a footrest body BD, and a clamp CP. This scaffold 13 has a certain distance from the handle so that the worker who climbs up the ladder so that the interference does not occur in the handle and the scaffold as shown in (3) of [8] but the depth of the groove is PG of [FIG. 9] The length should be at least half of the fist.

The footrest should be higher than the centerline of the pair of handles 12 forming a pair so as to stick to the ladder during movement, so that the bottom of the footrest should be higher as shown in FIG. 9. It must be larger than the outer diameter radius.

If the scaffold is long, for convenience of movement, the center or any position is cut and separated as shown in (2) of FIG. 8, and both ends of the scaffold are hinged, and the middle is fastened with at least two bolts. A connection point CT with fastener 1 (RH) and fastener 2 (RF) is added. When both ends of the scaffold are hinged, the fastener 1 and the fastener 2 of the connection point are punctured only by a hole, and the separated scaffold is straight.

If necessary, one end of the scaffold is hinged, the other end is clamped, and one of the connection points (fastener 1, RF) is hinged, and the fastener 2 is fastened by inserting a bolt nut. The footrest is divided as shown in (1) of FIG. 7 and (2) of [7], and when these are assembled, the footrest which has a hinge which can be rotated as shown in (3) of FIG. Becomes

 If necessary, a window that can be opened and closed on a part of the scaffolding, when the worker climbs up and down through the window when the worker goes up from the bottom up or down from the top, the worker will work up and down within the protected area by the railing of the bench. Fall can be prevented.

The handrail 14 and the brace 16 according to the present invention have one hinge (HD) and the other end as a clamp (CP), as in the scaffold, but the structural member such as a pipe or an angle is used for these hinges. Place them in the proper position for the scaffolding position and the brace position. All functions and structures of the hinges and clamps are the same as those of the scaffolding, and thus will not be described further.

The inclined column 15 is hinged at a certain position of the column 11 so that the simple work table is not inverted and supports a structure such as a pipe as illustrated in FIGS. 1 and 12 so as to contact the ground at an angle. Just do it. Here, the hinge should be provided with a means not to exceed a certain angle with the pillar 11, but it will not be described in detail any more since it is an easy means that can be carried out by anyone skilled in the art.
