Description

System for the provision of a support plane in sofas or similar.

Object of the invention

The present invention relates to a system for the provision of a support plane on sofas or similar, which provides essential novelty features and notable advantages with respect to the means known and used for them purposes in the current state of the art.

More particularly, the invention proposes the development of a system whereby it is possible to provide a  sofa or similar element, of a rigid plane, which is normally keeps hidden during normal use of the sofa, intended to provide the user with additional support that allows a increase in the possibilities of using it in others positions other than those of using a normal seat, for the sake of Improved comfort The system foresees the incorporation of elements facilitate the practicality of the rigid plane, so that once used, it can be returned to its hidden position, so that the sofa presents its normal appearance again.

The scope of the invention is obviously, within the industrial sector dedicated to the manufacture of sofas and other seating devices Similar.

Background and summary of the invention

The design is known to everyone in general usual with which different manufacturers usually provide sofas Indeed, a sofa element usually consists of a rigid structure that supports and supports a plane of seat, to a backrest plane, and in most cases, to lateral support elements or arms. As you know, the use normal of such a device consists of its use as a means of seating, for which they are manufactured normally enabled for two or three seats, depending on their dimensions. However, there is a large sector of the population that, at least at certain times, intends to take advantage of them to a more relaxed rest, in stretched or semi-detached positions along the seat plane, so that the arms of the sofa provide a support point for the back and / or head of the Username. This circumstance is often difficult to get, or at least not as comfortable as it would be desirable, since sometimes the stiffness of the arms prevents achieve the desired comfort, and in other cases, the arms of the sofa they don't provide the right height for this form of utilization.

Taking the inconveniences into consideration raised above, the present solution has been proposed  The main objective is to provide effective solutions to said problem, by incorporating in the sofa of practicable elements that, keeping hidden in their position of rest during normal use of the sofa (i.e. when only it is used as a seating means), can be shot down, removed or raised from such resting positions, and arranged on the arm of the sofa to which they are associated, as a continuation of it, and thereby provide a rigid plane that allows support against the same of some soft element, such as a pillow seat or an arm cushion, and thus allow a support of the User body part perfectly comfortable and suitable for The needs of relaxation and rest.

According to the invention, the support plane the sofa is arranged subject to it preferably folding, either with respect to a point or with respect to a edge of it, in a position close to the arm of the sofa, of such so that when the "opening" operation is performed, you can reach said overlap with respect to said arm. The different preferred embodiments that can be achieved by the system of the invention, include the use of means of hinge, pivot and / or retention, depending. decade concrete realization

Description of the preferred embodiments

As indicated above, the  detailed description of the preferred embodiments of the invention will be explained with reference to the drawings annexes, through which the same references are used numerical to designate the same or similar parts.

Thus, attending first to the representation of Figure 1, a form of provision of a rigid support plane on a sofa 1 that has been partially represented, schematically. In general, the normal presentation of the sofa is as seen in the lower representation, by means of the cushion 2 resting on the corresponding side arm, and with the seat pillow 3 on its condition of use However, when the user wishes make use of the sofa in other positions, partially laid out this length and with the back conveniently supported and supported, the mechanism provided by the mentioned plane can be extracted rigid support, and which generally consists of a flat element 4, preferably as a frame, board or similar, articulated to the structure 5 of the sofa along one of its edges, with the use of pivoting means 6 (for example, hinges, pivots with bushings, or similar), trained to allow a dejection of said plane 4 with respect to such hinges. By therefore, simply remove the lower pillow 3 located above plane 4, and raise the latter until it rests against the arm of the sofa, adopting a preferably inclined position as shows the representation that appears in the upper position of the Figure. With the support plane in that situation, it will be enough to return to place the pillow 3 in its normal position, thereby closing the seat plane, and apply a cushion 7 on the surface of the support plane 4, to provide the user with a means of comfortable and comfortable lift. Of course, the support plane 4 can be returned to its initial hidden position, under the pillow 3, repeating the operations in reverse order.

In the commented Figure 1, a detail enclosed within a circle, by means of which shows the case that the pivoting means are realized, in instead of using hinges, including a 6 'bolt at each side, linked both to the support plane 4 with the use of a bushing, like the frame 5 itself, and therefore serves as an axis of rotation during tilting operations.

The second embodiment that is represented also schematically in Figure 2 of the drawings, it is also of simple conception, and in this case the rigid plane of support is provided by a portion of the arm of the sofa 1. In In effect, said arm has a collapsible section 8, capable of stay complementary in a recess made in the arm of the sofa, and provided with a handle 10 located next to the edge away from the support plane the arm of the sofa. In correspondence with the opposite edge of this section 8, the articulation of said section with the use of means of hinged 9. For the use of the set, just do pivot section 8 with respect to the hinge means, until the section is brought to an inclined position similar to the shown in the second representation of Figure 2 considered. TO then, simply place the cushion directly on the surface plane of section 8, which provides a element that can be used by the user as a fanny pack or similar.

For the maintenance of section 8 in the fixed position desired by the user, the invention has provided that the pivoting means 9 consist of hinges 11, of the type known of those that incorporate a series of teeth that constitute fixing points in combination with an internal nail, and that allow retention release when taken to the end of your route and then returned to your position initial.

A third alternative is shown in Figure 3 of provision of support plane, in which the constituent element of said plane is associated with the back of the sofa 1. Indeed, in the resting condition, the support plane is hidden by means of a backup pillow 12; however, when you want to make use from it, said pillow 12 must be removed, so that the plane 13 is exposed. As seen in the representation central of this Figure, the support plane 13 appears hinged in 14 to the sofa backrest frame, in one position advantageously inclined. Thus, when you want to use the element 13, it will be enough to apply a traction on it by the opposite edge to the hinge, to take it to support against the arm of the sofa that occupies the adjacent position. Due to the inclination of said support element 13, upon reaching the edge of the arm of the sofa, will also be in an inclined position, as shown by dashed line in the third representation of This same figure. Then it will be enough to position the pillow 12, previously removed, against the corresponding face of element 13, to thereby provide an inclined plane that can be used by the user for the aforementioned effects of increased relaxation and rest.

Referring now to the alternative of embodiment shown in Figure 4 of the drawings, you can observe in this case the representation of a sofa 1 in which the support plane 15 is normally enclosed in the interior space of the arm of said sofa 1 itself, as it is represented with dotted lines in the first representation. In this way, when not in use, this element is hidden, without assuming therefore any obstacle to the use of the sofa in the way habitual. When desired, however, use the support plane as a support medium for a pillow 16, it will be enough to apply a tensile force on the handle 17, to swing at said support element 15 with respect to a pivot axis 18 which links it to the sofa structure, until it is completely extracted and take it to the position shown in the second representation of the figure. Then, as stated above, a pillow 16 resting inferiorly on the seat plane of the sofa.

As will be understood, in the present embodiment of the invention it is preferred that the upper edge of the arm of the sofa 1 is at a somewhat lower height than usual, as well as the the fact that the arm of the sofa adopts a somewhat inclined position in order to help better user positioning.

It will also be understood that item 15 constituting the support plane will have means to retain it in the operating position during use. The figure shows a example of a mechanism that could be used as a retaining means, and that essentially consists of a cap 19, consisting of a piece of adequate profile, which can be displaced against the action of a spring. For its part, element 15 has a recess in its edge, so that said stop can be housed in the recess of element 15, thus preventing the latter can be lowered to its resting position. Conversely, when the user wishes to take the rigid element 15 to the non-operative position, that is, housed in the interior space of the arm of sofa 1, it will be enough to exert a manual traction on the stop 19, against the action of the spring, to extract it from the inside from the recess and thereby freeing said element 15.

Figure 5 shows graphical representations schematized from an alternative embodiment of the invention, in based on two possible variants of it. Thus, in Figure 5.1, you can see a sofa 1 on whose respective arm appears a cushion resting on it, with a top 23 half extended horizontally over the arm, and with a half 24 bottom located inside the arm, resting against your face internal One of these halves, in this case the upper 23, is attached to the arm of the sofa by means of a hinge 25 (preferably of the same type as hinge 11 of Figure 2), such that said upper half 23 can be placed in elevated position, beyond the vertical, forming a support plane obtuse angle with respect to the lower half 24, appearing as a continuation of it, as shown in the second representation of said Figure 5.1.

In an alternative version, according to Figure 5.2, the two halves 23 ', 24' correspond respectively to the of the first version, although in this case the provision of the hinge 25 '(which as said will preferably be the same type than hinge 11 of Figure 2, that is, positionable by points), is performed between the arm of the sofa and the lower half 24 ', so that the latter can be elevated, when desired  provide the support plan, and arrange it as a continuation of the arm of the sofa, until beyond the vertical, forming angle external acute with respect to the upper half 23 '.

As will be understood, in both versions of the Figure 5, being the arm cushion itself that provides the support plane, the use of an additional pillow is discretionary, at the user's discretion. In addition, at least half 23, 24 'of the cushion that rises with respect to the arm of the sofa, It will have a stiffener inside, designed to also allow the holding of the other respective part of the hinge 25, 25 '.

Finally, according to Figure 6, may. appreciate in it an alternative form of realization, much simpler than the previous ones, and in which take advantage of the cushion 20 of the arm of the sofa 1, to get the support plane that is sought. In this case said cushion 20 incorporates a pair of pivots 21, emerging from its lower base, separated and parallel to each other, which in normal position are hidden in the sofa seat plane. However, the arm of the sofa 1 incorporates two holes 22, configured and sized in addition to the aforementioned pivots 21. Thus, when it is desired to form the support plane with said cushion 20 for the user, it will be enough to lift the cushion 20 from its usual position (first representation), and take it up place it on the upper edge of the arm of the sofa 1, introducing for this purpose the pivots 21 inside the holes 22. With this, it is possible to provide the backing that is search.

In the foregoing, each constituent element of the support plane has been defined as a rigid element. In the practice, said element will consist, preferably but not exclusively, on a flat, wooden or similar board, properly sized for the function mentioned.

It is not considered necessary to make the content of this description for a subject matter expert can understand its scope and the advantages derived from the invention, as well as develop and implement the object of the same.

However, it should be understood that the invention has been described according to a preferred embodiment thereof, so which may be subject to change without implying any alteration of the basis of said invention, being able to affect such modifications, especially the shape, size and / or to the manufacturing materials of the set or its parts
