RETRACTABLE STEP FOR USE AT HOME AND OFFICE

Abstract

It is intended to be used as a false drawer integrated in a drawer chest, screwed to the wall, which needs to have sufficient strength to hold the weight of the structure.

Can be implemented without consuming actual current usable space, so unnecessary use of extra space by external devices is avoided. Exceeds the mark of 50 centimeters and can reach even higher. The design mirrors the CE requirements.

It consists of a rigid structure that supports 3 steps which can fold and is integrated in a chest of drawers.

Claims

1. The invention is formed by a rigid metallic structure and steps, characterized because the complete structure and the three steps are embedded in regular guides within the interior of a furniture with multiple drawers, being one of these drawers the one that masks the invention.

2. This invention, according to point 1, is characterized because when unfolded and placed in the position of use, its is ready and secured blocking the structure and other drawers through the interaction of the structure and the chest of drawers.

3. A characteristic of the invention, according to point 1, is that it rotates, folding and unfolding, through some strips and a cross-piece, and the system can run along through the guides into the chest of drawers, which allows the invention be integrated as part of the furniture.

DETAILED EXPLANATION

[0014] This retractable model is formed by a movable structure as well as 3 steps meeting with the CE normative for stools. The invention is embedded, within regular guides of a regular drawer, inside a chest of multiple drawers, being one them the invention, which when pulled out, will unfold and will be positioned ready to be used. Once out of its folded position, the structure is secured due to its interaction in between the invention and the chest of drawers, avoiding unexpected movements from the invention. The invention is installed at its height of use, and attached to the furniture by the drawer guides, thus, enabling voluntary folding and or unfolding to the user wishes.

[0015] The support structure presents a dual role, supporting the weight of the user plus cargo up to 180 kg (limited to 180 kg for safety reasons), as well as the drawers.

[0016] Refer to FIG. 1 for the detailed components of the invention.

[0017] The vertical leg, 1, serves as support for the structure, holding up the steps, all performed through the components, 4. There is a long strip, 3, uniting it to the third step, 5, which enables to reach highest extension. The vertical leg, 1, has a metallic reinforcement, 13, which helps the support of the structure weight, as well as a reinforcement for the rail, 15, and the cross-piece, 16, which adds better stability to the support structure.

[0018] There are 2 cylindrical supports, upper, 2, and lower, 9, which enables the turn respective to the strips, log, 3, and small, 10. The long strip, 3, is joint to the steps support, 4, which enables extension of steps, third, 5, and middle, 7, reaching maximum longitude. The latter joint allows for the relative displacement in between them, so the invention masked as a drawer can open comfortably.

[0019] The third step, 5, is united to the support of steps, 4, and the strip of the second step, 6, through the connection of the L plates, 14, of the step, which they are simultaneously connected to the small strip, 10, and the guide, 11, enabling the movement between them, and its maximum extension, activating a small stop to avoid backward movements.

[0020] In the lower part, we have a horizontal leg, 8, connected to the strip of the second step, 6, the cylindrical lower support, 9, the small strip, 10 and the metallic reinforcement, 12.

[0021] Once in its final position, pieces are fixed through screws, creating a rectangular structure with all its components, granting the invention high level of solidity, stability and resistance. The weight of the user and eventual cargo in second and third step is of great stability thanks to the pair of forces neutralized.
