Three-Dimensional Residential Architectural Structure

The present application is a Continuation of International Application No. PCT/KR2023/001258 filed on Jan. 27, 2023, which claims priority to Korean patent application number 10-2023-0008541, filed on Jan. 20, 2023, which is incorporated herein by reference in its entirety.

The present invention relates to a three-dimensional residential architectural structure, and more particularly, to a structure capable of efficiently organizing residential space by dividing it into multiple three-dimensional spaces based on height, while minimizing the use of railings and stair structures to reduce the risk of falling accidents.

Recently, due to the increase in single-household dwellings, there has been a growing demand for compact residential units such as apartments, officetels, and studio-type housing, resulting in a trend toward smaller residential spaces.

Because such residential units typically have limited floor area, they often face constraints in efficient space utilization.

To address this, urban residential buildings such as officetels, studio apartments, and compact apartments have increasingly adopted duplex-type structures, where the floor-to-ceiling height of a single story is increased and the interior is divided into an upper and lower space, thereby enhancing the usability of the space.

Generally, in such duplex structures, a middle floor is installed within the interior space to divide it into an upper and a lower level.

In this case, the lower level is formed beneath the middle floor and is typically used as an active space, such as for working or daily living.

Accordingly, the middle floor is built with sufficient height to allow users to stand and move comfortably, and stairs or ladders are installed to provide access between levels.

However, when such duplex structures are applied, the height difference between the middle floor and the base floor can be quite large, which has frequently resulted in falling accidents—especially involving children—with many cases leading to serious injuries or fatalities.

Additionally, in small-sized duplex units, the staircases are often made steeper or replaced with ladders to reduce the space they occupy, which further increases the risk of falling accidents.

Accordingly, there is a need for a three-dimensional residential architectural structure that divides space vertically to enhance spatial efficiency while minimizing the risk of falling accidents.

An object of the present invention is to provide a three-dimensional residential architectural structure that enables efficient spatial organization by dividing a residential space into multiple three-dimensional spaces according to height, while minimizing railing and stair structures to reduce the risk of falling accidents and improve space utilization.

The technical problems to be solved by the present invention are not limited to those mentioned above, and other technical problems not explicitly stated herein will be clearly understood by those of ordinary skill in the art from the following description.

To solve the above-described problems, the present invention provides a three-dimensional residential architectural structure in which space can be separated based on the height of a residential space, the structure comprising: a first level disposed between a floor and a ceiling in a portion of the residential space and connected to the floor via stairs; a second level disposed between the floor and the ceiling at a position higher than the first level and configured to be movable with respect to the first level; and an extension member provided on a side portion connecting the first level and the second level, wherein at least a portion of the extension member is configured to be extendable and retractable in a horizontal direction. The second level is arranged such that it is accessible from the floor via the first level.

In addition, a first space having a first height is formed between the floor and the ceiling; a second space having a second height is formed beneath the second level; a third space having a third height is formed beneath the first level; a fourth space having a fourth height is formed above the first level; and a fifth space having a fifth height is formed above the second level.

The first space is disposed adjacent to each of the second through fifth spaces and is connected so as to allow access to the second space.

The second space is arranged to allow movement to the fourth space via the stairs.

Fall prevention facilities are provided on the first level and the second level adjacent to the first space.

The fall prevention facilities are operatively driven in conjunction with the operation of the extension member.

The structure further comprises a lifting member provided on the first level, wherein the height of the lifting member is adjustable between the first level and the ceiling, and the upper surface of the lifting member is usable as a work surface. Further, a plurality of the second levels may be provided within the residential space, each movably disposed with respect to a single first level.

A portion of the second level adjacent to the first level may be used as a desk surface.

Railings may be provided on the first and second levels adjacent to the first space to ensure visual openness.

The third space may be used for installing home appliances such as a washing machine, dryer, or freezer, or as a storage space; and the fifth space may be used as a sleeping area or for storage.

The fifth space may also be used as a multipurpose desk such as a table or vanity.

According to an embodiment of the present invention, a residential space can be efficiently organized by dividing it into multiple three-dimensional spaces based on living height, while minimizing railing and stair structures to reduce the risk of falling accidents and improve spatial utilization.

In addition, by reducing the height difference between the intermediate level and the floor compared to conventional duplex structures, the invention significantly improves safety by minimizing the likelihood of serious or fatal injuries in the event of a fall, resulting only in minor injuries at most.

The effects of the present invention are not limited to those described above, and additional advantages not explicitly mentioned will be apparent to those skilled in the art from the detailed description below.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The detailed description set forth below, together with the accompanying drawings, is intended to illustrate exemplary embodiments of the invention and is not intended to represent the only forms in which the invention may be implemented.

In the drawings, elements unrelated to the description may be omitted for clarity, and the same or similar reference numerals may be used throughout the specification to denote identical or similar components.

In the embodiments of the present invention, expressions such as “or” and “at least one of” are to be interpreted to mean any one or a combination of the listed items, unless explicitly stated otherwise.

In the following embodiments, the size, thickness, and shape of each component may be exaggerated for clarity and explanation, and may differ from those of the actual three-dimensional residential architectural structure.

Furthermore, references to upper, lower, lateral, etc., are made for convenience of description based on certain components, and may differ depending on the orientation or arrangement of the structure.

The three-dimensional residential architectural structure of the present invention may be applied to various buildings such as single-family houses, multi-family houses, apartments, row houses, multiplex houses, and dormitories, and is particularly suitable for residential spaces having a floor-to-floor height of approximately 4,500 mm or less and a ceiling height of approximately 4,300 mm or less.

Here, the “floor-to-floor height” refers to the vertical distance between the floor slabs of two adjacent stories based on a concrete structural frame, and the “ceiling height” refers to the distance between the floor and the ceiling within a single story, also based on the concrete frame.

A detailed description of a three-dimensional residential architectural structure according to an embodiment of the present invention will now be provided.

is a plan view of a three-dimensional residential architectural structure according to an embodiment of the present invention;is a view illustrating a first level according to the embodiment;is a view illustrating a second level according to the embodiment;is a cross-sectional view taken along line A-A′ of;is a cross-sectional view taken along line B-B′ of; andis a cross-sectional view taken along line C-C′ of.

Referring to, a three-dimensional residential architectural structureaccording to the present invention includes a floor, a ceiling, and first and second levelsand, which are installed at different heights between the floor and the ceiling.

The floor may be formed as a flat surface, allowing a user to safely walk and occupy the first story of the space.

As shown in, one or more pieces of furniture or facilities may be arranged on the floor.

For example, the floor may be furnished with items such as a sofa, rug, side table, storage cabinet, sink, and faucet.

The first levelis installed between the floor and the ceiling in a portion of the residential space and is connected to the floor via stairs. The second levelis installed at a height above the first levelbetween the floor and the ceiling and is disposed to be movable with respect to the first level.

For example, the first levelmay include a series of step-shaped platforms that function as stairs, allowing the user to step up from the floor through the first level to reach the second level.

The second levelis positioned higher than the first leveland is arranged to be accessible from the floor via the first level.

In one embodiment, at least a portion of the first levelmay be formed as a flat surface of sufficient area to allow for practical use by a resident.

A user may stand and engage in daily activities or install furniture on the first level, and in conjunction with the furniture placed on the second level, efficient spatial utilization may be achieved.

In conventional duplex residential structures, the space equivalent to the second levelis directly connected to the floor by stairs, which creates a large vertical drop and increases the risk of severe injury in the event of a fall.

Furthermore, in small-sized duplex units, staircases are often made steep or replaced with ladders to save space, which has also contributed to frequent fall-related accidents.

However, in the three-dimensional residential architectural structureof the present invention, the second level, which corresponds to the elevated space in a conventional duplex, is not directly connected to the floor. Instead, a first levelis additionally formed between the second leveland the floor.
