DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable foldable platform, and more particularly, to a portable foldable platform, which is made of a soft synthetic resin so as to cover an upper end portion of a leg portion which is closed at an acute angle with respect to a heaven. The present invention relates to a foldable step ladder having a protective sheet stretched to prevent a finger pinching accident.

[0002]

2. Description of the Related Art A portable foldable step ladder is usually provided as shown in FIG.
As shown in the figure, the upper ends of the legs 12, 14 are pivotally mounted on both sides of the heaven section 10, and a support member 16 is inserted between the intermediate portions of both the legs 12, 14, so that the whole is a pantograph type. It has a deformable structure.

When stored or transported, it is folded as shown in FIG. 5A, and when it is used, both legs are opened and assembled as shown in FIG. 5B.

[0004]

When such a folding step is used, when the two legs are opened from a state where both legs are closed for storage and transportation, it is enlarged in FIG. 5B. As shown in FIG. 6, the finger is often caught between the foot 10 and the ceiling 10 because the operation is often performed with the thumb placed on the leg top 12a. Indications such as "Pay attention to your fingers!" Are given on the relevant part because it is easy to be sandwiched structurally. However, it is not a drastic measure such as improving the structure, so safety such as caution at hand is ensured. It is the current situation that the task is left to the worker's consciousness.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a foldable step ladder having a structure capable of preventing a finger pinching accident when assembling with the legs opened.

[0006]

According to the present invention, the upper ends of the legs are pivotally mounted on both sides of the ceiling, and a support member is inserted between the intermediate portions of the legs, so that the whole is deformed in a pantograph manner. This is a portable foldable platform that has a possible structure, whereby both legs can be freely opened and closed. Here, in the present invention,
To prevent finger pinching made of soft synthetic resin between the upper side of the ceiling and the lower surface of the ceiling so as to cover the upper end of the leg that closes at an acute angle to the ceiling The protective sheet is stretched, which is characteristic.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic view of one embodiment of a folding stepping board according to the present invention. FIG. 2 shows a folded state (at the time of storage or transportation), and FIG.
Shows a front view, and (b) shows a side sectional view.

[0008] The portable folding platform itself may be basically the same as the conventional one as shown in FIG. Therefore, in order to simplify the explanation, corresponding members are denoted by the same reference numerals. The upper ends of the legs 12, 14 are pivotally mounted on both sides of the heaven section 10, and the supporting member 16 is inserted between the intermediate portions of the legs, so that the entire structure has a pantograph-type deformable structure. Thereby, both leg parts 12 and 14 can be opened and closed freely.

According to the present invention, the ceiling section 1 is so covered as to cover the upper end portion of the leg section 12 on the side closed at an acute angle to the ceiling section 10.
A protective sheet 20 made of a soft synthetic resin for preventing pinching of a finger is stretched between the upper surface side of the "0" and the lower surface of the ceiling portion. The protective sheet is made of a soft synthetic resin, and is preferably made of, for example, a PET (polyethylene terephthalate) -based material so as to be slippery. Fixing plates 22 and 24 are attached to two opposite sides of the protection sheet 20, respectively.
4 is fixed to the step body. Each of the fixing plates 22 and 24 has a bent shape at a substantially central portion. A protection sheet 20 is attached to one side of the fixing plate, and is fixed to the stepping body at the opposite side. The fixing plates 22 and 24 may be made of a hard synthetic resin or a metal such as aluminum. Attach with double-sided adhesive tape or adhesive.

In this embodiment, as shown in FIG. 2A, the protective sheet 20 has a substantially U-shape having a rectangular cutout 26 formed on one side. . A side opposite to the notch 26 of the protection sheet 20;
The fixing plate 22 and the fixing plate 22,
Attach 24.

One fixing plate 22 is provided on the top 10 of the platform.
To the side edge of the upper surface. Here, the fixing plate 22 is fixed so as to extend from the upper side edge to the side surface of the ceiling section 10.
The other fixing plate 24 (notch portion side) is fixed to a central rib 28 provided on the lower surface of the ceiling portion of the step platform. The fixing plates 22 and 24 are attached to the step platform main body with an adhesive or a double-sided adhesive tape from the viewpoint of strength. Of course, bolting or the like is also possible.

As described above, the protection sheet 20 is provided with the notch 26 on one side because the protection sheet 20 is transported and moved by using the bar-shaped portion on the upper part of the leg 12 as a handle when storing the platform. This is to prevent this function from being impaired.

FIG. 3 shows how the protective sheet 20 can prevent fingers from being caught when the leg is opened to use the step. (A) As shown in FIG.
Even if the leg is opened with the finger on a, the protection sheet 20 fixed to the heaven section 10 is pulled as shown in (b), so that the protection sheet 20 is pulled as shown in (c). The fingers are pushed out, so they are not pinched.

[0014]

As described above, according to the present invention, the upper side of the ceiling section and the lower surface of the ceiling section are formed so as to cover the upper ends of the legs on the side that closes at an acute angle to the ceiling section. Since the protective sheet made of a soft synthetic resin is stretched between the fingers, it is possible to prevent a finger pinching accident. Even when the step is opened while the finger is inadvertently placed on the leg top, the finger is pushed out of the gap between the leg top and the ceiling by the protection sheet, so that the finger is not caught. In addition, a protective sheet is pre-installed in a place where you can easily place your fingers, and the protective sheet moves when you open the platform, so you can feel uncomfortable and be alerted naturally and prevent your fingers from being pinched. it can. The mechanism for preventing the finger from being pinched by the protection sheet can be easily attached to an existing folding stepping board.

Claims (1)

(57) [Claims] 1. An upper end of a leg is pivotally mounted on both sides of a heavenly portion, and a support member is provided between both middle portions of the leg to form a pantograph-type deformable structure as a whole.
