Industrial application
[0001] Usable space at home is a critical element, regardless of the size of the house.
[0002] Even the people living in big mansions, eventually end up having problems to store
everything that accumulates in a life time which is difficult to get rid-off for different
reasons.
[0003] Even so more often, furniture producers design ingenious modular solutions to enable
further storage of clothing or else, which will not be used immediately. There is
a clear trend in the market pushing towards the improved use of the space in height,
which implies that it is not always easy to access belongings and therefore, we have
to make use of external tools, such as chair, stools or ladders.
[0004] The installation of wardrobes of great height to make good use of higher ceilings
is something more and more frequent in the current design of furniture for households,
as well as for offices.
[0005] In addition, the height of some people, as well as children, makes it more difficult
to reach certain high places at home or in the office.
[0006] Despite there are alternatives such as stools, steps, fixed or movable ladders, etc.
all of them present the inconvenience of space consumption as well limits in their
reach. Most of them cannot be over dimensioned and present the clear problem of where
to be stored when not in use. On top of that, most of them can carry additional burden
in terms of safety of use, due to the fact that they have not been design for such
use, potentially being a hazardous source for accidents.
Prior technique status
[0007] The invention is directed towards its use as an integrated step stool at home and
office spaces. Specifically, it is geared towards its use as an integrated autonomous
stool. In such design way, the use of unnecessary storage space or not-fit-for-purpose
devices is avoided.
[0008] There are several patents, such as
FR2972621,
GB2462462 or
US2015001005 that describe objects type stool or steps to access spaces in height. However, all
of them summarize in a couple of steps, attached to the floor through some legs and
that end up occupying more space that its own. Our invention is simpler and has visible
advantages in its use and manufacturing.
Explanation of the invention
[0009] The invention is directed towards its use as an integrated step stool at home and
office spaces. This is an autonomous model, without visible legs when unfolded. It
is developed to hold up all efforts when stepping in as well as all efforts coming
from its parts. It is integrated and can be installed without consuming current usable
space, so unnecessary use of extra space by external devices is avoided. Step up exceeds
the mark of 50 centimeters and can reach even higher.
[0010] It consists of a rigid structure that supports 2 steps which overlap, slide and fold
through some bearings until the end of the structure, decreasing the space occupied
by the invention. The invention is fixed where the user cannot see, thus giving the
impression the steps hold off in the air.

Detailed explanation
[0012] This model is divided in two parts: Steps and support structure. Steps act as support
for the user, meanwhile the structure secures the combined weight of steps and user.
The invention is embedded inside a furniture made out of one or multiple drawers.
[0013] Firstly, the invention is positioned at the height of use, so its use is more ergonomic,
providing a better user experience avoiding excessive flex.
[0014] Due to its positioning, it provides a high lift, thus enabling the user to properly
access greater heights. Installation is recommended to not exceed excessive heights
for comfort of use and safety.
[0015] Secondly, the support structure presents a dual role, enabling the support of the
steps as well as the user plus cargo up to 180 kg (limited to 180 kg for safety reasons)
[0016] In figure 1 the invention components are detailed. The smoldered and screwed support
structure, 1, is the guide as sustains 2 steps and the movement system. The step has
a bearing, 2, that serve for an easy movement through the structure thus guiding the
steps, integrated in the design. Underneath, we can find the smoldering assembly,
3, which function is to hold both the upper step, 4, as well as the bearings, 2. A
strip, 5, connects the upper step, 4, with the lower step, 6. This union assures a
fluid movement versus the structure as it allows for a turn of the lower step, 6,
so it may remain at the same height of the upper step, 4. The turn is possible due
to a screwed hinge, 7, which allows for the strip to move. The strip is also connected
to the base of the upper step, 8. In summary, the system allows that strip and lower
step rotate, to reach maximum extension so the lower step gets over the upper step.
Once folded, and both steps in the same plane, the bearings, 2, allow the steps to
move towards the metallic structure, 1. Once all is together, it becomes a stable
and solid structure, and it can be hidden as a drawer. Visually integrated in the
furniture as if it did not exists.
[0017] When the invention is unfolded, the user and cargo weight is push by design to the
metallic structure and to the wall that it is anchored. This enables the invention
to be very stable, due to the different force pairs which neutralize among them.
1. The invention is formed by a rigid metallic structure and steps, characterized because
the complete structure and the two steps are embedded 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 one of its steps folds
over the other through a strip and a hinge, and both can run along into the structure
through the use of bearings, which allows the guide to be integrated as part of the
furniture.
3. A characteristic of the invention, according to point 1., is that the support of the
invention are not visible to the user.
4. The invention has the guides integrated, according to point 1., so it could work with
the furniture or independently of it.
