BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ladder installed on a floor surface and an intermediate floor between the ceiling and the floor surface, and more specifically, to enable a ladder to be safely climbed from any place on the intermediate floor. It is related to the technology to be tried.

[0002]

2. Description of the Related Art Conventionally, a ladder installed on a floor surface and an intermediate floor between the ceiling and the floor surface is a ladder that is hung on a specific portion of the intermediate floor and climbs to the intermediate floor from the specific position. is there.

[0003]

[Problems to be Solved by the Invention] However, in such a structure, the ladder is hung at a specific position on the intermediate floor, and cannot be climbed from other parts of the intermediate floor. Since it is put on, there is a problem that this is an obstacle and it is inconvenient to use. The present invention is intended to solve such a problem, and the purpose thereof is to allow a ladder to be safely climbed from any place on the intermediate floor and to prevent the ladder from being obstructed when not in use. It is to provide a safe and easy-to-use ladder that can be moved to a place where it does not become a problem.

SUMMARY OF THE INVENTION The ladder of the present invention is a ladder installed on a floor surface and an intermediate floor 1 between the ceiling and the floor surface, and a rail 2 is provided at the front edge of the intermediate floor 1. Of the ladder A
The upper end A ₁ extends above the rail 2 and
It is characterized in that at a position below the upper end of the child A, an engaging tool 3 slidably engaged with the rail 2 is connected to the back of the child A.

[0005]

[Operation] In this way, the ladder erected on the floor surface and the intermediate floor 1
By extending the upper end of the child A above the rail 2,
Above the rail 2 of ladder A when getting on and off the floor 1.
You can hold the part A ₁ extended to the
Installed at the front edge of the intermediate floor 1 behind the upper end of the child A
Engagement tool 3 that slidably engages the rail 2 is connected
By doing so, it extends above the rail 2 of ladder A.
It is engaging member 3 and the rail 2 when having been partial A ₁ by hand
It will not get in the way and you can safely get on and off the intermediate floor 1
It can be done smoothly .

[0006]

1 to 3 show a first embodiment, in which a ladder A has a tread plate 5 installed between left and right handrail frames 4. A rail 2 is formed over the entire length of the front edge on the front surface of the intermediate floor 1 of the storage part such as the ceiling. This rail 2 is formed of a channel material with a lip as shown in FIG. 3 (a), and a pair of runners 6, 6 are slidably inserted into the rail 2, and the rail is extended over the pair of runners 6, 6. A rod-shaped hanging tool 7 as an engaging tool 3 is provided outside the housing 2, and large-diameter caps 8 are fitted on both ends of the hanging tool 7. And ladder A
A pair of hooks 9 and 9 are attached to the side. here
Then, the upper end of the ladder A is
It is extended also upwardly, hand the extended portion A ₁
I can hold it at. Also as the engagement tool 3
The rod-shaped hook 7 is located below the upper end of the ladder A.
It is placed behind it. Therefore, a pair of hooks 9 and 9 are hung on the hanging tool 7 so that the ladder A can be installed between the floor surface and the intermediate floor 1.

In this way, the rail 2 is provided on the intermediate floor 1, and the hook 7 slidably engaged with the rail 2 is hooked on the hook 7 to be connected to the ladder A side.
Can be easily moved to any position, and the intermediate floor 1
You can climb from anywhere. In this case, the hooks 7 on the ladder A side are engaged with the hooks 7 that are engaged with the rails 2 on the intermediate floor 1 side, and the ladder A will not be disengaged even if it is moved to any position, which is safe. is there. When it is not used, the ladder A is moved to the end of the rail 2, that is, the end of the room so as not to get in the way. A hook 16 for hanging and storing is attached to the ladder A.

FIGS. 4 and 5 show a second embodiment, in which the ladder A is divided into upper and lower halves 10 and 11, both are slidably connected, and a stay 12 is attached to the upper half 10. The runner 6 is attached via the runner 6, and the runner 6 is suspended and fitted on the rail 2 as the engaging tool 3 so that the upper and lower half bodies 10,
In a state where 11 is slid and folded, the hook 13 of the lower half body 11 is hooked on the pin 14 of the upper half body 10, and the ladder A
It can be stored in a short state. The design of folding the ladder A short can be changed in various ways.

6 (a) to 6 (c) show a third embodiment, in which a handrail 15 is erected on the intermediate floor 1, and the handrail 1
The ladders A are stopped at a plurality of places where no stands, so that the intermediate floor 1 can be climbed. Specifically, a rail 2 is formed on the front edge of the intermediate floor 1, and a runner 6 on the ladder A side is suspended and inserted on the rail 2 as an engaging tool 3 so that the rail 2 can run freely.

[0010]

As described above, the present invention has a floor surface, a ceiling, and
A ladder to be installed on an intermediate floor between the floor and the intermediate floor
A rail is provided on the front edge of the ladder, and the upper end of the ladder is
Since it is extended upwards, when getting on and off the intermediate floor
Hold by hand the part that extends above the ladder rail.
And at a position below the top of the ladder
An engaging tool that slidably engages the rail is connected to the back.
Part of the ladder that extends above the ladder rail.
The engagement tool and rail do not get in the way when holding the minute by hand.
As a result, it is safe and smooth to get on and off the intermediate floor.
Can be done. Moreover, the ladder can be easily moved to any position, and the intermediate floor can be climbed from any position.In such a case, the engaging tool that runs on the rail on the intermediate floor side is engaged with the ladder side. , It is safe to move it to any position, and it is safe, and when not in use, it can move the ladder to the end of the room without getting in the way and improving its usability.
