CHAIR DECOMPOSABLE INTO TWO CHAIRS INDIVIDUALLY USABLE AND CONSEQUENTLY ASSEMBLABLE IN A BENCH OR A ROW OF CHAIRS

Abstract

 Chair decomposable into two chairs individually usable and consequently assemblable in a bench or row of chair. The two chairs are separable from each other with simple movements and are usable individually and interchangeable. The two separate chairs can be hooked so as to form a two-seat bench with backrest. More chairs allow to develop benches or longer rows of chairs depending on the number of originating chairs.
The two separate chairs can be hooked together by turning one of the two of a 180° angle with respect to the vertical axis so as to form opposing seats. The same invention is applicable to a chair without backrest or to a table with different shapes and dimensions.

Description

[0001] The present invention relates to a chair that can be separated into two chairs individually usable and subsequently assemblable in a bench or a row of chairs; the invention is applicable to different forms of seats and furnitures that can be manufactured in different materials such as wood, plastic, aluminium, steel.

[0002] Currently are known or available on the market, besides the classic chair, the following types of chair: the folding chair, stackable chair, chair linkable in a row, double or single chair separable into two chairs individually accessible which did not have market penetration due to the varied technical and functional limitations. For example, the patent - application n° ITPD-2008-A-114 - grant n° 1390598 - merely an extension of the chair by turning it into a double seat without possibility of separation; the same solution was proposed earlier in the patent - ITBO1993A000496 - at fig. 10 and 11. Or in a utility model - ITUD2007U000006 - the two overlapping chairs have, separating them, different heights of the seats. The utility model - ITMI1994U000600 - the chair that consists of two overlapping chairs is the seat higher than the seats of the two separate chairs. In utility model - DE202004002567U1 - which incorporates a patent - GB190606884A - we merely transform the chair into a bench.

[0003] The today known solutions do not consider the following possibilities.

to transform the single seat into two sittings usable separately and hookable together to form a row of chairs or a bench with backrest, developable also with opposable sittings and with the same level and depth of sitting, easily, without the usage of disassembly tools and/or mechanisms, without holes, without complex maneuvers and/or overexertion;

to apply the invention to different materials such as wood, wood and upholstery padding, plastics, steel and aluminum, and padding, etc. with infinite variations and combinations with one another;

to apply the invention to different forms of seating and furnishings based on specific uses, for example, dining chair, relax, study, chair or armchair, stool of varying height with or without backs and/or armrests, benches of varying depth and height, tables and consoles of various sizes, for furnishing indoor and/or outdoor places.

[0004] The purpose of this invention is to solve the problem as mentioned above.

[0005] The invention although adaptable to various forms and functions, is applied to the chair as follows:

The chair of origin consists of two single chairs wedged between them so they look a single chair and usable as such. The two chairs are separated from each other with simple movements of one of the two named chair (1), with respect to the other that we will call chair (2); both the chairs are available separately and are interchangeable with the same level and depth of the seat and also the same backrest angle.

[0006] The two separated chairs, chair (1) and chair (2), can be fitted one to the other to form a two seat bench with backrest with the sequence (1) (2) or (2) (1). More chairs of origin allow you to develop longer rows of chairs or benches. For example, two chairs of origin generate four chairs, two chairs (1) and two chairs (2), that can be hooked together using the sequence (1) (2) (1) (2) or (2) (1) (2) (1) and so on endlessly on the base of the number of chairs of origin available. In addition, two separate chairs, chair (1) and chair (2), can be joined one to each other by turning one of two 180° angle from the vertical to form opposing sittings.

[0007] The chair (1) is composed of an even number of flat and variously shaped and spaced parallel elements that form two inverted "U" as legs, shown in drawings with elements (1.3) and that form the seat/backrest as "L" shape, as shown in drawings with elements (1.4); these elements are connected and appropriately spaced by two elements arranged at right angles to them called cross elements of chair (1) shown in drawings with elements (1.1-1.2). The profiles of the chair (1) have a section and a position as to allow the overlap of the chair (1) with respect to the chair (2).

[0008] The chair (2) consists of an odd number of flat and variously shaped and spaced parallel elements to form two inverted "U" as legs, shown in drawings with (2.3) and to form the seat/backrest as specified in drawings with elements (1.4); these elements are connected and appropriately spaced by two elements arranged at right angles to them called cross elements of chair (2)- The profiles of the chair (2) have a sectional and a position as to allow the overlap of the chair (2) with respect to the chair (1).

[0009] In chair (1) and in chair (2), the distance between the elements (1.3), (1.4), (2.3), (2.4), and the thickness of the same elements is such as to allow a comfortable sitting of individual chairs, chair (1) and chair (2), and their combinations.

[0010] You can accomplish the same thing by replacing the cross element (1.1), (2.1), (1.2), (2.2), with spacer elements placed between the elements (1.3), (1.4), (2.3), (2.4) so as not to interfere the overlap of the chairs, chair (1) and chair (2), and their combinations. The elements making up the seat/backrest (1.4) and (2.4) can be splitted into two individual elements, the backrest and the correspondent seat elements, and can be connected to their respective cross elements (1.2) and (2.2) in such a way as to ensure structural continuity of the chairs (1) and (2).

[0011] Please note that to use the chair decomposable into two chairs, individually usable and subsequently assembled in a bench or a row of chairs, no further disassembly tools and/or mechanisms, fixing, complex maneuvers and/or excessive strain are needed.

[0012] In the initial situation the two chairs (1) and (2) are combined to set up a single chair in appearance and function.

[0013] The separation of the two chairs

First phase: the chair (1) is moved forward on the front side up to allow the front cross element of chair (1), indicated with (1.1), to overcome the edge of the seat and the front legs of chair (2) such as shown in drawings with elements (2.3).

Second phase: rotation of the chair (1) with axis of rotation on the back cross element of chair (1), indicated with (1.2), to the point that (1.1) exceed the edge of the seat of the chair (2); follows the horizontal movement back of the chair, chair (1), keeping it tilted up to overcome with the back cross element (1.2) the rear edge of the seat/backrest of the chair (2); vertical movement of the chair (1) up to the top of the backrest of chair (2); at this point the two chairs are separated. The recomposition of the two chairs in a single chair is done by running the sequence of separation backwards.

[0014] Hooking of separate chairs (1) and (2) to form a bench or row of chairs
The hooking takes place by simple joint of the chair (2) with the chair (1) by lifting it just enough to slide from above the shaped element constituting the legs, right or left side, of the chair (1) such (1.3), among the element of these (2.3), left or right side, of the chair (2) and the first element of these (2.4), left or right side, of the chair (2). The hooking can also take place in opposite sittings as described in the drawings.

[0015] The sitting was designed to solve the problem encountered in all those situations where it is necessary to increase the seats in self-sustaining manner and instantaneous in the same room or compartment. For example, in case of guests, after having stretched the dining table, the invention allows to find the missing chairs without recover from other rooms; similarly resolve the problem of the second chair in the room, the study room or in the hotel room, in meetings and / or dining rooms, meeting the need for flexibility and adaptation of the seating allowing you to create benches or seats linear file a further increase in seats in both private and public environments.

[0016] The invention may be made variants to the size of the elements that make it up and the number of parallel variously shaped elements according to the type of use required.

[0017] For example, in the case of application of the invention to the stool, the same one will have dimensions and number of elements appropriate to the specific function, so for the bench, the table, the tea table, the relaxation sittings, etc. with the obvious care to avoid distorting the functioning system described above which claims the invention novelty.
