Detailed description

In the illustrated exemplary embodiment, the individual features illustrated in connection with a particular implementation can in fact be substituted for other different features present in other exemplary embodiments.

Furthermore, it should be noted that what has turned out to be known during the patent process is understood not to be claimed and is the subject of a disclaimer.

With reference to the drawings, the reference 1 generally designates a multifunctional sheet unit, which comprises a frame 2, which is constituted by a pair of supports 3a, 3b, these supports 3a, 3b, 3b intersect in an X-like configuration.

A pair of supports 3a, 3b define a pair of first legs 4a, 4b and second legs 5a, 5b, which legs 4a, 4b, 5a, 5b are pivoted in an X-like configuration, the upper part Associated with the first plate 6 and the second plate 7 at one end in the region, the first plate 6 and the second plate 7 are arranged opposite to each other and have a substantially trapezoidal shape when viewed from the front.

Such first and second plates 6 and 7 have long parallel sides 8a, 8b and short parallel planes 9a 9b, the long parallel sides 8a, 8b being directed towards the floor and the short parallel planes 9a 9b being pointed It is parallel to one of the (long parallel sides 8a, 8b) and is directed in the opposite direction.

The long parallel sides 8a, 8b are mixed together by the short parallel sides 9a, 9b and the first inclined sides 10a, 10b, the first inclined sides 10a, 10b being the first legs 4a, 4b and the second legs 5a, 5b. Intersect at the pivot point 11 of, and by their second side 12a, 12b they are inclined and directed towards the outside of the seat unit 1 and have a low inclination with respect to the inclination of the first side 10a, 10b .

In the situation in which the seat unit 1 illustrated in FIGS. 1 to 4 is lowered and enlarged to define the armchair 13, the first side 10a, 10b is such that a first V-shaped split 14 is formed between them Position.

The first ends of the first arm rest 16 and the second arm rest 17 are rotatably associated by means of the first sliding or guiding bars 15a, 15b, the first sliding or guiding bars 15a, 15b being associated with the second side At the intersection between 12a, 12b and the long parallel sides 8a, 8b, the seat unit 1 is arranged longitudinally.

In the illustrated embodiment, by means of a non-limiting example, to fix the first ends 20a, 20b of the adaptation straps 21a, 21b which are subsequently floor-directed on the first bars 15a, 15b, the second The bars 19a, 19b are longitudinally and stably positioned relative to the seat unit 1 at the free second ends 18a, 18b of the first arm rest 16 and the second arm rest 17.

For sliding or guiding the straps 21a, 21b disposed above the third bars 22a, 22b, the third bars 22a, 22b are longitudinally with respect to the seat unit 1, the second side faces 12a, 12b and the short sides. It is located at the intersection between parallel sides 9a, 9b.

The third bars 22a, 22b are located in a plane located above the plane where the first bars 15a, 15b are located or in the same plane at most in the movement of the seat unit 1 in any state.

The second ends 23a, 23b of the straps 21a, 21b are longitudinal with respect to the seat unit 1 and are associated with the fourth sliding or guiding bars 24a, 24b, the fourth sliding or guiding bars 24a, 24b being X In a region adjacent to the pivot point 11 of the cross-over supports 3a, 3b, it is connected between the sheet uni and the first legs 4a, 4b and the second legs 5a, 5b of the one.

The fourth bars 24a and 24b are located below the plane in which the first bars 15a and 15b are located in a region near the pivot point with respect to the third bars 22a and 22b in all states of movement of the seat unit 1 Located on a plane.

The seat unit 1 comprises a rear part 25 which is constituted by a first case 26a and a second case 26b, which are transversely foldable on a fixed central support 27.

Each of the first case 26a and the second case 26b includes lower end surfaces 28a and 28b, third outer side surfaces 29a and 29b, fourth inner side surfaces 30a and 30b, and upper end surfaces 31a and 31b, and the lower end surface 28a. , 28b are located above the first leg 4b and the second leg 5b, and the first leg 4b and the second leg 5b are disposed on the back of the seat unit 1, and the third outer side 29a, 29b. Are connected to the first armrest 16 and the second armrest 17, respectively.

The fourth side surface 30a, 30b is shown in FIGS. 1 to 4 as is shown in FIGS. 1 to 4 so as to define the armchair 13, and the fourth side 30a, 30b is a second V-shaped split 32 hidden by the central support 27. Is positioned such that it is formed between the fourth side 30a, 30b.

The fixed central support 27 is stably connected to the first case 26a and the second case 26b by elastic means.

The multifunctional seat unit 1 comprises the seat unit 1 illustrated in FIGS. 5-8 so as to define a limiting and blocking means, such as a first V-shaped split 14, at least one spring-like assisting means, and a chair 33. In the state of being raised and contracted, means for rotating the first armrest 16 and the second armrest 17 are provided.

In order to complete the seat unit 1, the fitted cushion 34 can be arranged on the seat portion 35 laterally at the rear on the armrest.

In a state where the seat unit 1 is lowered and enlarged so as to define the armchair 13, the first plate 6 and the second plate 7 are located on the same horizontal plane, and the first plate 6 and the second plate 7 There is a first V-shaped split 14 between them, the first armrest 16 and the second armrest 17 are inclined outward, and there is a second V-shaped split 32 between the first case 26a and the second case 26b of the rear portion 25. , The second V-shaped split 32 exposes the central support 27 acting as the back 25.

The transition from the state in which the seat unit 1 is lowered and expanded to the state in which the seat unit 1 is raised and contracted so as to define the chair 33 is produced by the rotation of the first arm rest 16 and the second arm rest 17 The straps 21a, 21b are tensioned and the force of the adapted guides on the first bars 15a, 15b and the third bars 22a, 22b, the pair of first legs 4a, 4b and second legs 5a, 5b The rotation and the rotation of the first plate 6 and the second plate 7 are forced, which constitute the supports 3a, 3b crossed in an X-like arrangement.

In a state in which the seat unit 1 illustrated in FIGS. 5 to 8 is lifted and contracted to define the chair 33, the first plate 6 and the second plate 7 are inclined to form a pair of first legs and a second leg. The legs have a structure formed like X when viewed from the front, and the first side faces 10a and 10b of the first plates 6 and 7 contact each other to close the first V-shaped splits 14 Placed, and thus, the first V-shaped split 14 limits the transmittable rotation to the supports 3a, 3b crossed in an X-like configuration.

The first arm rest 16 and the second arm rest 17 are disposed substantially parallel to each other, and the fourth side surfaces 30a, 30b of the rear first case 26a and the second case 26b are placed in contact with each other.

So that the invention achieves the intended purpose and purpose completely, while saving space, different types of applications, in particular the situation where the seat unit 1 is lowered and expanded to define the armchair 13, the chair It can be seen that a seat unit 1 has been obtained which makes it possible to take advantage of the situation in which the seat unit 1 is raised and reduced to define 33, quickly and easily.

From this, it was found that the seat unit 1 optimizes the space in the internal environment of the residential facility.

Since the seat unit 1 maintains the ergonomic characteristics of the armchair and maintains the ergonomic characteristics of the chair without changing it, there is no need to add parts to perform switching, and the assembly operation It turned out that it is structurally simple and it is simple to move from the fact that a simple mechanism works with a simple motion without having a.

Finally, it has been found that the invention makes it possible to achieve satisfactory aesthetic results, is low cost and that a customary conventional system is provided.

The present invention is subject to numerous variations and modifications, all of which are within the scope of the appended claims.

Of course, the individual components of the invention as well as the materials used may be more appropriate according to the specific requirements.

Features described above as advantageous and convenient may also be missing or replaced with equivalent features.
