DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ladder constructed by connecting both side girders and a plurality of horizontal rails between them.

[0002]

2. Description of the Related Art In a conventional ladder, a ladder is simply constructed by connecting both side girders and a space therebetween by a plurality of foot rails.

[0003]

However, when the ladder is used underground or in a dark place at night, its contour is difficult to determine, and therefore, there is a danger in ascending and descending using the ladder. There is a risk of causing an accident such as falling off the ladder. In addition, when moving near the ladder, there is a possibility that the ladder may collide with the ladder because the existence of the ladder is unclear.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to arrange a reflector on each of the horizontal rails of a ladder to ascend and descend. The aim is to provide a safe and low risk ladder.

[0005]

In order to achieve the above object, a ladder provided with a reflector according to the present invention is provided with a ring-shaped footrest at least at one end of each crosspiece and inside a joint with a side beam.
And the inner circumference of the ring
A reflector having a reflecting portion is arranged.

[0006]

[Function] Since the ladder is constructed as described above, when using this ladder underground or in a dark place at night,
Since even a small amount of light is reflected by the reflectors arranged on each side rail of the ladder, the outline of the entire ladder can be clearly confirmed, and there is no danger of climbing up and down using this ladder, Not only is there no danger of an accident such as a fall, but also when moving near the ladder, the presence of the ladder can be confirmed and the ladder is hardly hit. Also reflection
Put the body in a ring shape and fit it around
An uneven reflector is formed on the inner circumference of the ring, so the reflector
Is extremely easy to mount and secure
it can.

FIG. 1 is a partially cutaway perspective view of a ladder according to an embodiment of the present invention, FIG. 2 is a front view of the ladder according to the present invention, and FIG. 3 is a sectional view taken along line AA of FIG.

In the drawing, reference numeral 1 denotes a side beam, which is located on both sides of a foot rail 2, and a plurality of the horizontal bars 2 are arranged between the both side beams 1. Reference numeral 3 denotes an insertion hole for the cross beam 2 formed from the inside of each side beam 1. A ring-shaped reflector 4 is fitted and arranged at the end of each of the cross rails 2 on the inner side of the joint with the side beam 1. This ring-shaped reflector 4 may be arranged inside each of the side girders 1 and 1 as shown in FIG. 2, or may be arranged only inside one of the side girders 1. Alternatively, the end of the horizontal rail 2 may have a small diameter, and the ring-shaped reflector 4 may be fitted and arranged in the small diameter part, so that the outer periphery of the reflector 4 and the outer circumference of the horizontal rail 2 may be flush.

With the reflector 4 fitted in the outer periphery of each of the cross rails 2, the end of each of the cross rails 2 is inserted into the insertion hole 3 provided in the side beam 1 and locked by the pin 5. . The end of the cross beam 2 may penetrate the side beam 1 and may be fixed to the side beam 1 on the outer surface of the side beam 1 by a nut or a pin.

As described above, the reflector 4 is ring-shaped and fitted on the outer periphery of the horizontal rail 2.
Is formed of polycarbonate, acrylic resin, or other transparent polymer material having an uneven reflecting portion 6 formed on the inner periphery thereof.

Although the cross bar 2 is shown in the drawing as having a circular cross section, its cross section may be square, and in the case of a ring-shaped reflector 4, its cross sectional shape is the cross sectional shape of the cross bar 2. It is good to match.

Since the ladder is constructed as described above, when the ladder is used underground or in a dark place at night, even a small amount of light is reflected on each of the cross beams 2 of the ladder. Because the light is reflected by the ladder, the outline of the entire ladder can be clearly confirmed, and there is no danger of ascending or descending using the ladder, and there is no danger of causing an accident such as falling off the ladder. When moving near the ladder, the presence of the ladder can be confirmed, and the ladder rarely hits the ladder.
In addition, the reflector has a ring shape and
And formed an uneven reflector on the inner circumference of the ring.
The reflector is extremely easy to install and maintain
Can be reliably held.

[0013]

According to the present invention, in a ladder constructed by connecting both side girders and a space between them by a plurality of horizontal rails, a reflector is arranged at least at one end of each horizontal rail inside the joint with the horizontal girders. Therefore, when using this ladder underground or in dark places at night, you can clearly see the outline of the entire ladder,
There is no danger of climbing up and down using this ladder, and there is no danger of an accident such as falling off the ladder, and even when moving near the ladder, the presence of the ladder can be confirmed and it will hit the ladder It becomes a safe ladder with few things.

Further, fitting the outer circumference of the leg rest for rungs of the reflector as a ring-shaped, so to form an uneven reflective portion inner periphery of the ring, the holding attachment of the reflector together with a very easy It becomes a ladder that can be surely done.
