Definitions

  • This invention relates to a sofa with a device for regulating the hardness of a seat in such a way that it can easily be adapted to the user's preferences.
  • a device that allows the hardness of the seat to be modified by the user him/herself and, therefore, avoids deformation of the seats due to their use is therefore required.
  • This problem is solved by the sofa with a device for regulating the hardness of a seat which is the object of this invention.
  • the resiliency of the slat support elements will remain essentially unaffected as long as said adjustable support members are positioned in close proximity to the sides of the frame so that the bed frame assembly and, consequently, the bed as such provide a soft support to the body, whereas the resiliency of the slat support elements will be progressively reduced, resulting in a progressively firmer support of the frame assembly and the bed as the distance between the adjustable support members and the sides of the frame is increased so that the slat support elements have their deflection characteristics varied.
  • Document GB1263377A discloses a mattress support comprising a rectangular frame having resilient support elements extending between two parallel limbs of the frame, and two stiff bearer bars arranged on the frame transversely beneath the support elements and being mounted for movement either (a) to and from a position in which they engage the support elements or (b) to various positions of engagement with the support elements, to vary the yield of the support elements under load.
  • an object of this invention is the sofa with the device for regulating the hardness of the seat module. More specifically, an object of the invention is to enable each user to achieve an adapted degree of hardness quickly and easily. These objects are achieved with the sofa according to claim 1.
  • the flexible elements can be configured -in two practical, non-limiting embodiments- in elastic straps and/or flexible plastic suspension slats.
  • plastic parts exist for joining the slats of settees and mattress bases which, by joining them together, can slightly increase or reduce the hardness of the suspension, but the difference in hardness achieved is minimal, whereas, thanks to this invention, it is possible to achieve extreme differences in hardness.
  • the rigid element is configured as a bar that exerts pressure on the lower part of the flexible elements (either straps or slats) such that, as it moves or changes position, it causes a change to the hardness of the seat.
  • This rigid element can be motorised, or it can be an element that can be moved manually between predefined positions, which, in the tests performed, makes it possible to go from 100% flexibility of the flexible elements -in other words, without the rigid element exerting any action or force on the flexible elements- to 30% or 40% of the original flexibility of said elements, for example, by placing the rigid element in a centred position with respect to the flexible elements that constitute the support of the seat cushion.
  • each user can regulate the hardness of his/her seat, and different types of hardness, harder or softer, can coexist in the same sofa.
  • This choice of hardness is totally reversible.
  • the sofa comprises two seat modules (10, 20) where the seat cushions themselves will be located.
  • both seats (10,20) it can be seen how they are configured by a plurality of flexible elements (11,21), which, in this practical embodiment are flexible plastic slats, they could also be flexible straps.
  • These flexible elements (11,21) are arranged transversally with respect to the seat, in other words, they have the same maximum length as the seat and are configured as the lower support for the cushions that makes up said seat, as indicated above.
  • a motorised rigid element (12) is arranged perpendicularly to the flexible elements (11) configured in an embodiment that is in contact with the lower surface of the flexible elements (11) and configured to exert pressure on said flexible elements during their displacement.
  • the rigid element (12) is movable from a first working position, wherein the rigid element (12) is fully retracted into the internal part of the seat (i.e., the part closest to the backrest) and wherein it exerts no pressure on the flexible elements (11) to a second working position, wherein the rigid element (12) is in a closed centred position with respect to the length of the flexible elements (11), such that it exerts a maximum pressure on said flexible elements (11) and consequently increasing the sensation of seat hardness.
  • the rigid element (12) moves on an axis (13) arranged in the middle of the seat which is operated manually by means of a motor (14) and which, due to its backwards to forwards movement, and vice versa, manages to regulate the flexibility of the flexible elements (11) and, therefore, their hardness.
  • a second practical embodiment can be seen, more specifically, in the second seat (20).
  • the flexible elements (21) are located identically to those of the first embodiment, but there is no motorised axis, but two guides (22 and 23) are simply positioned on both sides of the seat, facing each other and in parallel.
  • Each of the aforementioned guides (22,23) has a plurality of housings (24) suitable for manually receiving a rigid element or crosspiece (12) in the housings (24), depending on the hardness required, by manually positioning the bar between a first working position, wherein the rigid element will be more to one side, or in any other more centred working position and defined by each pair of housings (24) facing each other.

Claims (1)

  1. Sofa mit einer Vorrichtung zum Regulieren der Härte eines Sitzmoduls (10, 20), wobei das Sofa Folgendes umfasst:
    eine Rückenlehne;
    zwei Sitzmodule (10, 20), in denen die Sitzkissen selbst platziert werden; und
    wobei das Sofa eine Vielzahl von ersten flexiblen Elementen (11, 21), die sich als unterer Träger für die Sitzkissen befinden, und ein starres Element oder einen Querträger (12) umfasst, das bzw. der zwischen einer Vielzahl von Arbeitspositionen in dem Teil unmittelbar unterhalb der Vielzahl von flexiblen Elementen (11, 21) beweglich ist und mit diesen senkrecht in Kontakt steht, sodass in jeder Arbeitsposition ein anderer Druck von dem starren Element (12) auf die flexiblen Trägerelemente (11, 21) ausgeübt wird;
    wobei das starre Element oder der Querträger (12) Folgendes ist:
    ein motorisiertes starres Element (12), das auf einer Achse (13) beweglich ist, die im mittleren Bereich des Sitzmoduls (10) angeordnet ist und mechanisch mittels eines Motors (14) betrieben wird, der dazu konfiguriert ist, das motorisierte starre Element (12) zwischen der Vielzahl von Arbeitspositionen zu bewegen, von
    (a) einer ersten Arbeitsposition, wobei das starre Element (12) vollständig in den inneren Teil des Sitzes in dem Teil, der der Rückenlehne am nächsten ist, zurückgezogen ist und wobei es keinen Druck auf die flexiblen Elemente (11) ausübt,
    zu
    (b) einer zweiten Arbeitsposition, wobei sich das starre Element (12) in einer geschlossenen, zentrierten Position in Bezug auf die Länge der flexiblen Elemente (11) befindet, sodass es einen maximalen Druck auf die flexiblen Elemente (11) ausübt und folglich das Gefühl der Sitzhärte erhöht;
    und/oder
    wobei das starre Element oder der Querträger (12) manuell zwischen verschiedenen Positionen bewegbar ist, die durch zwei Führungen (22, 23) auf beiden Seiten des Sitzmoduls (20) definiert sind, die einander zugewandt und parallel liegen, wobei jede der Führungen (22, 23) eine Vielzahl von Gehäusen (24) aufweist, die geeignet sind, das starre Element oder den Querträger (12) aufzunehmen, und wobei jedes Paar von gegenüberliegenden Gehäusen (24) eine Arbeitsposition definiert, um einen unterschiedlichen Druck von dem starren Element (12) auf die flexiblen Trägerelemente (21) auszuüben.
