Abstract

The present invention relates to a foot rest for a step for a structure ladder, and the fixing parts are bent on both sides of the supporting part, and the supporting part provides a step for the ladder coated with a light emitting body, so that a separate reflector does not have to be configured. The number of parts and the working process are shortened, and in particular, since the entire supporting part emits light, the position of the step can be easily known even at a long distance, so it can be effectively evacuated in an emergency.

Description

Steps for Structure Ladders {STEP FOR LADDER OF STRUCTURES}

The present invention relates to a step for a structure ladder.

Normally, lifting means are provided to access various structures such as floors, culverts, and engines. In recent years, ladders for entering and evacuating workers have been installed in underground facilities such as storage facilities, subways, and tunnels. Such a ladder is constructed by arranging a plurality of steps that serve as handles and scaffolding in a row so that an operator can enter and exit.

These steps are mainly composed of '??' shapes and are arranged at equal intervals in the vertical direction.

3 shows a configuration of a conventional ladder step. Looking at this, fixing parts 12 that are bent approximately 90 degrees in the same direction are integrally formed at both ends of the supporting part 10. In addition, a covering portion 20 is provided that surrounds the support portion 10 and extends to a portion with the fixing portion 12. The supporting part 10 and the fixing part 12 are made of a rod-shaped metal material to sufficiently withstand the load when the operator moves up and down. On the other hand, the coating part 20 is used as a foot support part when the operator moves up and down, and also serves as a gripping part. Therefore, since the slip is required to be small, mainly composed of synthetic resins. As it is composed of synthetic resin, it is possible to provide a soft touch when gripping.

On the other hand, the support portion 10 is provided with a reflector 22 to facilitate the location of the pedestal. This is provided at both ends of the supporting portion 10 to be able to know the range of the supporting portion 10, is provided to reduce the risk of the operator's foot.

However, the conventional step for ladders having such a configuration is not easy to identify the position, and furthermore, there is a problem that a limitation is involved in accurately recognizing the range of the supporting portion.

That is, in the related art, although the reflectors 22 are provided on both sides of the supporting part 10, the reflector 22 is inserted into the cover part 20 as shown in FIG. It is difficult for the operator to check the position of the pedestal from a distance. Therefore, there is a fear of increasing the damage to people in an emergency, and in particular, because of the nature of the reflector, it is impossible to identify the location without light, so when used in underground facilities, etc., it is more difficult to identify the location.

In addition, the workability was inferior due to an increase in the number of parts and an increase in the process due to the installation of four separate reflectors.

Therefore, the present invention was devised in view of the above problems, and it is easy to identify in the dark, so it is easy to identify the location (step) of the doorway at a distance, and further, for the structure ladder to induce rapid evacuation in case of emergency. In providing a step.

The purpose of the present invention can be achieved by the step of the structure ladder is bent formed on both sides of the support portion, the support portion is coated with a light emitting body.

It is preferable that the above-mentioned light-emitting body comprises an appropriate ratio mixture of a synthetic resin and a fluorescent agent or a photoluminescent agent.

Hereinafter, a preferred embodiment of the step for a structure ladder according to the present invention with reference to the accompanying drawings in more detail.

1 and 2 are a perspective view of a step for a structure ladder according to the present invention. The present invention is described with the same reference numerals as in the prior art. The fixing part 12 bent by approximately 90 degrees in the same direction at both ends of the support part 10 is comprised integrally. In addition, the light emitting unit 30 is provided to surround the base 10 and extend to a part of the fixing unit 12. The light-emitting body 30 is made by mixing a light-emitting pigment with a synthetic resin at an appropriate ratio. As the light emitting pigment, a fluorescent agent or a photoluminescent agent is used. Preferably, it is effective to use a photoluminescent agent. That is, the photoluminescent agent has the same basic properties as the phosphor, but unlike the phosphor, it has a property of being emitted as light energy again for a predetermined time by light energy previously received even when the light is blocked.

Phosphorescent pigments are energy sources that can absorb light, such as natural light, incandescent lamp, and artificial light used in daily life. In terms of efficiency, sunlight, mercury lamp, fluorescent lamp, etc. .

The present invention having such a configuration is provided with a light-emitting body 30 is a mixture of synthetic resin and light-emitting pigments at the periphery of the support portion, it is possible to easily grasp the position of the step in the emergency in underground facilities such as dark storage and subway without light Will be. Particularly, the light emitting body holds light energy by natural light at the position where light is emitted and emits light at night, and electricity is supplied smoothly in underground facilities such as underground storage and subway where no light is emitted. It receives enough light energy to emit light and emits light when an outage occurs in an emergency, so that people can be effectively evacuated. This can be used more effectively in the dark where no light is emitted.

As described above, the step for the structure ladder according to the present invention is formed by covering the light emitting material of the fluorescent material or the phosphorescent material on the periphery of the supporting part so that a separate reflector does not have to be configured, so that the number of parts and the working process are shortened. Since the whole emits light, it is possible to easily know the location of the entrance and exit of the structure even at a long distance, so it has the advantage of effectively evacuating in an emergency.
