    [0002] Adjustable firmness device and rest furniture comprising said device
    [0004] The present invention relates to an adjustable firmness device that can adjust its firmness, for example, by means of an external actuator control, and to a rest furniture comprising said device.
    [0006] Rest furniture are those elements of furniture that have among their functions that of rest. Rest furniture are, for example, mattresses, couches, chairs, armchairs, sofas, pillows, cushions, etc. The present invention is of special application to mattresses, chairs, armchairs and sofas, although the present invention is not necessarily limited to such applications.
    [0008] Adjustable firmness devices are known that allow the user to condition the firmness of the rest element by means of a mechanism, in order to be able to adapt the firmness to each user and each moment.
    [0010] The adjustable firmness devices that currently exist on the market work through various systems, such as: the use of air chambers as an intermediate layer of the mattress or as an insert in one of the foam layers; the use of ropes in the upper part of the spring block; or the use of systems that vary the working height of the elastic elements from the bottom of the same in order to change the initial length of the elastic elements.
    [0012] More specifically, European patent document ES2414656 discloses a furniture device that comprises a firmness adjustment by separating two plates adjacent to a group of elastic elements. A deformation element is provided that displaces one of the plates vertically to increase or decrease the deformation of the elastic elements from below them. A problem that the invention ES2414656 presents resides in the area of action since the plate acts on the elastic group completely, another problem of ES2414656 is found in the impossibility of being able to maintain the height of the elastic element throughout the entire path of the plate.
    [0014] PCT patent document WO2014117995 discloses a firmness and height adjustable mattress. The regulation of the firmness is done by increasing or loosening the tension created on non-elastic cords located in the upper part of the spring block, parallel to the resting surface while the height is regulated by means of cams that push the elastic element from the lower part. A problem that this invention presents is the low comfort it presents since the firmness is regulated by the tension of some strings transverse to the mattress and therefore the body of the sleeper does not rest on the springs but on strings.
    [0016] PCT Patent Document WO2005053466 discloses an adjustable firmness spring mattress that uses one or more air chambers arranged under the springs. By inflating or deflating these watertight chambers, the initial length of the spring can be modified by compressing it from its underside. A main problem with said invention is the difficulty of keeping the height of the upper layer of the springs constant when the air chamber is inflated or deflated.
    [0018] It is an object of the present invention to provide an adjustable firmness device for rest furniture that does not have the aforementioned disadvantages.
    [0020] To this end, the present invention discloses an adjustable firmness device in which by using heads that compress one or more elastic elements from the upper part that absorb just the energy of each element so that the area of action of said device has the desired thrust.
    [0022] More particularly, the present invention discloses a device capable of regulating firmness by varying or absorbing the elastic force exerted by one or more of the elastic members in one or more layers of the rest furniture. In accordance with the present invention, the modification of firmness is achieved by decreasing / increasing the density per resting surface area of the active elastic elements, thus reducing / increasing the pressure exerted by the elastic members against the user. Reducing the density of elastic elements per unit area - or the work area in the case of a single elastic element-, reduces the total elastic constant of the set of elastic elements and, therefore, that of the furniture. break. This is achieved through the use of, in each elastic element to be activated / deactivated, a head placed on top of each elastic element and a means that transmits a traction force to the head for compression of the elastic element, thus absorbing part of the elastic energy by reducing the sum of the elastic constant of the set.
    [0023] The present invention discloses both variable firmness devices and lounging furniture comprising such devices.
    [0025] More specifically, the present invention discloses an adjustable firmness device comprising a resting surface, a plurality of elastic elements located under the resting surface, at least one rigid base element on which the elastic elements rest, in such a way so that the elastic elements are intended to receive pressure from the resting surface, being compressed, and regain their original shape when said pressure disappears, in which at least some of the elastic elements comprise:
    [0027] - a head in the upper part of the elastic element;
    [0028] - a tension transmission means applied to the head,
    [0030] the tension transmission means (s) being connected or connected to an actuating device of the tension transmission means, in such a way that the action of the actuating device causes a compression of the element or of the elastic elements connected through the respective means of transmission of tension.
    [0032] The compression of the elastic element (s) is carried out by means of a head in the upper part and a rigid element in the base, in such a way that, preferably, a rope is passed through the rigid element, the end of which is attached to the head in order to perform a tension force on the rope and thus compress the elastic element (s). Being elastic, the elements, once the compression force exerted on them has ended, return to their original shape.
    [0034] The means by which the tension is transmitted from the actuator to the elastic element can preferably be any flexible element that only transmits tensile force and never compression. Most preferably, the tension transmitting means is a rope, a wire or a cable.
    [0036] The means of actuation to pull the ropes may be by means of an electric or rotary linear actuator, or manually by means of a crank system. Preferably, the actuator device has means for adjusting its action in order to be able to produce compressions of different magnitudes. Even more preferably, the device actuator is an electric, mechanical or hydraulic linear actuator, an electric, mechanical or hydraulic rotary actuator. In the present invention, a hydraulic actuator is considered to be an actuator that, through the use of a fluid or gas under pressure, transmits a force or a couple of forces, a definition commonly used in the field of the art in which it is framed the invention.
    [0038] The actuator device can be actuated, preferably, with a command connected by cable, by a radio frequency device, by an RFID device, by means of a bluetooth receiver and a computer application; a WiFi device or mobile network; by an electronic or computerized artificial intelligence system or manually by means of a system of cranks and / or cams that are actuated by the force of a person.
    [0040] Preferably, the actuator device is anchored to the rigid base element. It can be located, for example, on the rigid base, at the bottom or even inside the rigid base element.
    [0042] Preferably, said elastic elements are springs, or a set of springs, or a foam block or a set of foam blocks.
    [0044] The rigid base element may preferably consist of a plate or a joint of them, a support structure or a joint of them. Preferably, it may be composed of one or more materials such as, for example, wood, metal, polymers or fibers bonded by resin.
    [0046] The adjustable firmness device object of the present invention is intended to be inserted into any piece of furniture intended for rest / comfort, and one or more devices can be included in the same piece of furniture. The device is especially applicable to mattresses, chairs, armchairs, sofas or armchairs, although the invention is not necessarily limited to said application. The device of adjustable firmness object of the present invention can be inserted in one of the layers of the rest furniture.
    [0048] In short, the furniture object of the present invention has an adjustable firmness device that, by means of a flexible tension transmitting channel attached to a head, can absorb part of the elastic potential energy of the elastic element or elements on which it is applied. wants to act by exerting a force to compress said elements, in order to regulate the pressure exerted by the element or elastic elements on the consumer of the product.
    [0050] More specifically, the present invention discloses a rest furniture that comprises an adjustable force device to compress elastic elements, in such a way that a pressure force is received from the rest surface, compressing it and recovering its original shape when said pressure disappears.
    [0052] For better understanding, attached, by way of explanatory, but not limiting example, drawings of various embodiments of the adjustable firmness device, object of the present invention.
    [0054] Figure 1 shows, schematically, a front elevation view of the first embodiment of an adjustable firmness device in the rest position, in the maximum firmness configuration of the mattress.
    [0056] Figure 2 shows a front elevation view of the adjustable firmness device of the previous figure in a contracted position, the minimum firmness configuration of the mattress.
    [0058] Figure 3 shows a section of a second embodiment of an adjustable firmness device controlled by a linear actuator, its internal elements being visible.
    [0060] Figure 4 shows a section of a third embodiment of an adjustable firmness device controlled by a rotary actuator.
    [0062] Figure 5 shows a perspective view of the adjustable firmness device of the previous figure, in a state of rest
    [0064] Figure 6 shows a perspective view of the adjustable firmness device of the previous figure, in a contracted state.
    [0066] Figure 7 is a perspective view of a fifth embodiment of an adjustable firmness device with a foam block as an elastic element.
    [0068] Figure 8 is a perspective view of a sixth embodiment of an adjustable firmness device with a profiled foam block as an elastic element.
    [0069] Figure 9 is a perspective view of a seventh embodiment of an adjustable firmness device with a set of foam blocks as elastic elements.
    [0071] Figure 1 shows a set of elastic elements 1, 11 arranged on a rigid plate 4. A linear actuator 3 is arranged on the plate 4. Some elastic elements 11 have heads 2. As can be seen in the figure, the forces F are transmitted from the actuator passing through the rigid base 4. The force transmission means F (for example, wires or ropes 6) is connected to a connecting piece 8 of the transmission means to the actuator to pull said means. As it passes through the rigid plate 4, the force vector F changes direction according to a component perpendicular to the elastic elements. The force F ends up being applied on the heads that are on the upper face of the affected elastic elements 11 to exert a pressure that causes a compression of said elastic elements 11. Although the action of figures F has been represented, the Figure 1 shows an example of the state of rest of the elastic elements, in which no forces are produced F. In the state of rest, the device presents its maximum firmness, which is transmitted to the rest surface of the rest furniture in the the device is installed (neither the resting surface nor the furniture have been represented in the figures).
    [0073] Figure 2 shows in a side view the same device as the firm 1 with the elastic elements 11 compressed thus offering the minimum firmness of the device.
    [0075] In the case of Figures 1 and 2, the elastic elements are bags made of material with elastic properties.
    [0077] Figure 3 shows a second embodiment of an adjustable firmness device which has a rigid base in the form of a structure 5, with a linear actuator 3 within said structure 5 and the threads 6 in charge of compressing the elastic elements 11 through the heads 2 located in the upper part of the elastic elements 11. In the case shown the elastic elements 11 consist of springs 12 pocketed.
    [0079] Figure 4 shows a third embodiment of an adjustable firmness device that is similar to that of the previous figure, with a difference in the actuation method, since the tensioning of the wires 6 is carried out by means of a rotary actuator 7, which transforms their torque in a traction force on the wire (s). The rest of the elements are similar to the previous embodiments and have been identified with identical numerals.
    [0080] Figures 5 and 6 show a fourth embodiment of an adjustable firmness device, similar to the previous ones, with a rigid base in the form of a structure 5 and with elastic elements 1, 11 in the form of pocket springs. In this embodiment, some elastic elements 11 can be compressed at will, while other elastic elements 1 cannot. Figure 5 shows the state of rest where all the elastic elements 1, 11 are at the same height since there is no tension in the cords or threads. This situation corresponds to the maximum firmness of the device. Figure 6 shows the state of maximum tension of the cords or threads, in which the selected elastic elements 11 are contracted due to the force exerted by the actuating device. This situation causes that the density of elastic elements per surface has been reduced. This situation therefore corresponds to the minimum firmness of the device. Between the state of rest (figure 5) and that of maximum tension (figure 6) there are infinite points of compression of the elastic elements, which translates into an infinite range of different strengths. For this, the force exerted by the actuating device must be adjustable.
    [0082] Figures 7, 8 and 9 show, respectively, three devices with adjustable firmness with a rigid base in the form of a structure 5 and elastic elements 1, 11 made of foam. Figure 7 shows a unitary foam block 11. However, the unitary foam block has a plurality of heads 2 operable through an actuator device (not shown in the figure). Figure 8 shows various elongated blocks of profiled foam, in which some blocks are non-operable elastic elements 1 and other elastic elements 11 are operable foam block elements. The operable foam blocks have a plurality of compression force receiving heads 2. Finally, in Figure 9 shows a set of individual foam blocks, each foam block constituting an elastic element. Likewise, the device has elastic elements 11 that can be actuated and cannot be actuated.
    [0084] The devices shown in Figures 1 to 9 may be located within a resting piece of furniture (not shown) as part of the device that provides firmness to a resting surface. For example, the devices shown can be arranged immediately under the resting surface (with the upper part of the elastic elements in contact with the resting surface), or they can constitute one of different layers of furniture comfort. In general, the elastic elements of the device object of the present invention can be arranged as elastic elements of the rest furniture of known type.
    [0085] The features shown in each of the different embodiments can be applied to other embodiments, and combined with each other. Thus, for example, the base of the embodiment of Figures 1 and 2 can be applied to the rest of the embodiments, for example, by fixing the actuation devices to the lower part of the plate 4. In general, the base will be fixed, for example For example, by fixing to the rest of the rest furniture. Likewise, the type of elastic elements can be interchanged. As an example, different size foam blocks, single foam blocks, springs, pocket springs, hollow elements made of elastic material, chambers, profiles made of synthetic material, and so on can be used as elastic elements.
    [0087] Although the invention has been presented and described with reference to embodiments of the same, it will be understood that these are not limiting of the invention, so that multiple construction details or other details could be variable that may become evident to the technicians of the sector after interpret the subject matter disclosed in the present description, claims and drawings. Thus, all variants and equivalents will be included within the scope of the present invention if they can be considered to be within the broader scope of the following claims.
