Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ladder,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fixing ladder with enhanced safety, and more particularly, to a ladder capable of supporting a ladder when it is fixed and a ladder capable of rotating according to an angle.

A ladder is a tool widely used in a construction site. When the ladder is used for construction work, the floor may not be fixed. If the stability of the ladder is deteriorated, there is a risk of a safety accident.

In order to solve such a problem, there is a ladder which can be stably fixed, such as a ladder for a sign work with an enhanced safety, in the patent document 10-2010-0133068. However, even if the ladder is added with a fixing device, there is a limit to fixing it on the floor. Further, in some cases (for example, when the floor is slippery or when the floor is sloped due to rain, etc.), the general ladder is fixed and used at risk.

However, if the ladder is fixed at risk, it may be unstable if it crashes at high altitudes, or when it is working on a ladder.

Patent Literature 10-2010-0133068 (title of invention: ladder for signboard work with enhanced safety)

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a fixing ladder capable of fixing a ladder more stably and increasing the degree of precision regardless of an angle.

According to an aspect of the present invention, there is provided a ladder having a footrest on which a person can stand and a support member contacting the floor, the lid comprising: a fixing cap installed at both ends of the ladder; A dragged portion located on the ladder and made of rubber or urethane material; A pair of connecting rods having a cylindrical structure rotatable by 180 degrees and a through hole into which the connecting rods are inserted, the connecting rods being fixed by the fixing plugs; And a connecting part fixing the fixing device to the ladder to match the height of the fixing device with the ground according to the angle.

As described above, according to the fixing ladder having improved stability according to the present invention, the ladder can be more stably fixed at the floor where it is difficult to fix, and further, the risk of the work can be reduced with the angle being less affected.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains.

FIG. 1 is a front view of a fixing ladder according to an embodiment of the present invention. FIG. 2 is a plan view of a fixing ladder having improved safety according to an embodiment of the present invention. And Fig.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a fixing ladder with enhanced safety according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

Referring to FIG. 1, the ladder for fixing according to the present embodiment with improved safety comprises a fixing device 5 having a foot 1, a support 6, a fixing stopper 13, (11).

The fixing device 5 according to the present embodiment includes a support base 6, a fixing cap 13, and a connection portion 11.

As shown in FIG. 1, the fixing device 5 is formed to be fixed horizontally with respect to the lower end of the ladder. 1, a fixing stopper 13 is formed on both ends of the ladder 2 so that the user can hold the fixing stopper 13 by a finger (thumb and index finger) and fix the fixing stopper 13 . At this time, the stopper 13 may be made of rubber or the like so that the hand does not slip smoothly.

The support 6 is a part that comes into contact when it is fixed to the floor, and is used to prevent slippage with the ground. The support base 6 can be made of rubber or urethane material capable of increasing frictional force. The pull-tab 9 located at the upper portion is a portion of the wall such as a wall, which is also made of rubber or urethane material.

2 is a plan view of a fixing ladder with improved safety according to an embodiment of the present invention.

As described above, there is a drag (170), which is located at the upper and lower ends. Referring to FIG. 1, a ladder 2 can be identified, wherein the footrest 115 shown in FIG. 2 is connected to the ladder 2 of FIG. The stopper 210 is configured to be connected to the securing device 118. At this time, the fixing stopper 210 is configured to be included with the fixing device 118.
