Description

Ladder for preventing fall {LADDER PREVENTING FROM FALL DOWN}

The present invention relates to an anti-fall ladder that prevents the ladder from falling during the ladder operation.

As everyone knows, ladders are designed to help you climb up and down high and low, and are divided into straight ladders and fold-out ladders with roughly “A” shapes.

In an environment where work is required at a relatively high position, heavy equipment such as a crane is used instead of a ladder, but a ladder is mainly used in a place where the height is not relatively high even in a building or an outdoor workshop.

When performing work using a ladder, it is common for other workers to grab the ladder from the ground in addition to the worker who climbs the ladder to increase the stability of the work, but it is difficult for two people to work in pairs due to the nature of the work site. There was this.

In order to solve this problem, a safety ladder equipped with an outrigger having various structures for preventing the ladder from falling, that is, falling over, has been developed and marketed in recent years.

However, since the outrigger of the conventional ladder described above has a folding structure and is mounted on the ladder, there is a hassle of having to manually unfold the outrigger every time the ladder is used. Due to this hassle, the ladder is inverted while the work is performed without using the outriggers.

In addition, when using the ladder for a long time there was a problem that the outrigger is not smoothly folded due to problems such as the hinge portion to break the outrigger folded.

The present invention is devised to solve the conventional problems as described above, the object of the present invention, and fixedly mounted so as to extend across the lower end of the leg frame of a pair of ladders fixed horizontally extending to the outside of each leg frame By providing an outrigger, it is possible to provide an easy-to-maintain and preventable ladder for the outrigger that can solve the trouble of having to unfold the outrigger every time a ladder is used.

In order to achieve the object of the present invention as described above, the present invention,

In the fall prevention ladder having a pair of leg frames, a ladder body consisting of a plurality of footrests provided between the pair of leg frames, and a fixed outrigger fixedly mounted to the ladder body,

Fixed outriggers,

A pedestal arranged horizontally at the bottom of the pair of leg frames; And

It provides a fall prevention ladder having a; bracket for fixing the pedestal to the leg frame.

The pedestal horizontally connects one leg frame to another neighboring leg frame, and one end and the other end of the pedestal extend horizontally to the outside of the adjacent leg frame.

The bracket is composed of a first fixing piece that is in close contact with the outer surface of the leg frame, a second fixing piece and a third fixing piece which is bent vertically on one side and the other side of the first fixing piece and extends to one side and the other side of the pedestal. The first fixing piece is fixedly mounted to the leg frame by screws, and one side and the other side of the pedestal are attached to the second fixing piece and the third fixing piece by screws under a state disposed between the second fixing piece and the third fixing piece. It is fixedly mounted.

Preferably, the non-slip block is fitted to one end and the other end of the pedestal, the non-slip block is a non-slip body fitted to the end of the leg frame, a fan-shaped integrally formed in the lower portion of the non-slip body and the bottom is in close contact with the ground It is made of a close contact of the shape, the knurled groove is formed on the lower surface of the close contact to prevent the sliding in contact with the ground.

As described above, the fall prevention ladder according to the present invention is provided with a fixed outrigger fixedly mounted on the bottom of the pair of leg frames constituting the ladder body, each time the operator must use the ladder to unfold the outrigger There is an advantage to solve the hassle.

1 is a perspective view showing a ladder for preventing falling according to the present invention, and
FIG. 2 is an enlarged perspective view of the fixed outrigger shown in FIG. 1.

Hereinafter, with reference to the accompanying drawings will be described for the fall prevention ladder according to an embodiment of the present invention.

1 is a perspective view showing a ladder for preventing falling in accordance with the present invention.

1, the fall prevention ladder 10 according to the present invention includes a ladder body 12 and a fixed outrigger 100 fixedly mounted to the ladder body 12.

As anyone can see, the ladder body 10 consists of a pair of leg frames 14 and a plurality of scaffolds 16 installed between the pair of leg frames 14 (straight ladders), or two It consists of the ladder main body 10 and the hinge part 18 which connects the upper part of two ladder main bodies 10 so that folding is possible (foldable ladder which has "A" shape). Figure 1 is a folding ladder is shown, it will be described based on the folding ladder.

FIG. 2 is an enlarged perspective view of the fixed outrigger shown in FIG. 1.

1 and 2, the fixed outrigger 100 includes a pedestal 110 disposed horizontally at the lower end of the pair of leg frames 14, and the pedestal 110 is fixed to the leg frame 14. And a bracket 120 to be mounted.

First, the pedestal 110 has a horizontal bar shape. The pedestal 110 horizontally connects one leg frame 14 and another leg frame 14 adjacent to each other, and one end and the other end of the pedestal 110 to the outside of the adjacent leg frame 14. Extend horizontally.

In FIG. 1 and FIG. 2, a pedestal 110 having a rectangular bar shape is illustrated, but it will be appreciated by anyone who is not limited to the rectangular bar shape of the shape.

Meanwhile, the bracket 120 is disposed between each leg frame 14 and the pedestal 110 to connect the pedestal 110 and the leg frame 14. The bracket 120 is bent vertically on one side and the other side of the first fixing piece 122 and the first fixing piece 122 that is in close contact with the outer surface of the leg frame 14 and one side of the pedestal 110 And a second fixing piece 124 and a third fixing piece 126 extending to the other side. As shown, the first fixing piece 122 is fixedly mounted to the leg frame 14 by screws, and one side and the other side of the pedestal 110 is the second fixing piece 124 and the third fixing piece 126. It is fixedly mounted to the 2nd fixing piece 124 and the 3rd fixing piece 126 by a screw as shown in the state arrange | positioned in between.

As described above, the non-slip block 130 is fitted to one end and the other end of the pedestal 110 disposed below the leg frame 14 by the bracket 120. The non-slip block 130 is a non-slip body 132 that is fitted to the end of the leg frame 14, and a non-slip body (132) formed integrally with the lower portion of the non-slip body 132 and the lower portion is in close contact with the ground ( 134). A knurled groove 136 is formed on the lower surface of the curved close leg 134 to prevent sliding when in contact with the ground. And the non-slim body 132 fitted to the leg frame 14 is fixedly coupled to the leg frame 14 for the screw as shown.

The fixed outrigger 100 according to the present invention formed as described above can solve the hassle that the operator must unfold the outrigger 100 directly when the ladder 10 is working.

In addition, by coupling the non-slip block 130 to the end of the pedestal 110, it is possible to prevent the ladder 10 from slipping during the operation of the ladder 10 as well as the non-slip block 130 in close contact with the ground. Since the lower portion has a curved shape, even if the ladder 10 is unfolded at various angles, the close contact leg 134 is always in close contact with the ground.

Meanwhile, an auxiliary pedestal (not shown) may be further provided inside the pedestal 110 having both ends closed by the non-slip block 130, and the auxiliary pedestal may have a non-slip block 130 of the pedestal 110. It is arranged to be accessible from the inside to the outside, or from the outside to the inside of the removed state to extend the length of the outrigger 100 to give the worker a psychological safety when working the ladder 10.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be able to variously modify and change the present invention without departing from the spirit and scope of the present invention described in the utility model registration claims. It will be appreciated.
