Abstract

Starting from an elongated working platform assembled on a scissor-type foldable structure, said platform has the particularity of being fragmented into three sectors (1), (2) and (3) hinge-connected to one another through a pair of links (5) and with the collaboration of two pairs of transverse shafts (7) connecting each link (5) with the two platform sectors between which it is located, such that when the ironing board is in an inoperative state, the end sectors (2) and (3) of its platform can be folded over the upper face of its intermediate sector (1), with a drastic dimensional shortening of the board. In parallel, the scissor-type lower structure also has the legs thereof fragmented into two foldable spans also allowing a drastic shortening thereof in an inoperative state, such that they do not project with regard to the intermediate sector (1) of the platform when folded over the lower face of the latter.

Description

OBJECT OF THE INVENTION

The present invention refers to an ironing board, i.e. to a support for clothing during ironing operations thereof, having a special application in the domestic scope.
The object of the invention is to achieve an optimal degree of foldability, determining a minimum space occupation for it in an inoperative state.
The invention is therefore within the scope of domestic use mechanical devices, and more specifically within the scope of ironing accessories.

BACKGROUND OF THE INVENTION

As is known, ironing boards receive this name since they were originally materialized in an elongated wooden platform that was basically rectangular, but having one of its ends narrowed with a triangular configuration, a platform supported by a generally metal structure suitably lifting it with regard to floor level so that the ironing is comfortable.
Currently, and even though the name "board" is maintained, the working platform has evolved into a metal structure, specifically a sheet metal structure, its contour being duly edged for strengthening its structure, the platform thus becoming lighter in weight and the useful life thereof being prolonged.
Since the use of ironing boards is sporadic within the aforementioned domestic scope, the working platform support is materialized in a scissor-type structure based on two double legs, such that one of them is hinge-connected to the lower face of the platform, whereas the other one is connected to the cooperation of slides, provided with locking means, so that said scissor can adopt a working position in which it suitably lifts the platform with regard to the floor, or so that it can be adapted to the lower face of the platform, converting the ironing board as a whole into an essentially flat element, which obviously facilitates storage thereof.
However, the dimensions of the ironing board in said inoperative state are determined by the working platform dimensions, from which platform the legs or support structure noticeably project at its ends.
This implies that even though the ironing board tends to have the flat configuration in said inoperative state, its length substantially limits its storage possibilities, since it requires a space for that purpose, for example, a closet, the height of which at least coincides with the length of the platform, and in most cases even exceeding said length.

DESCRIPTION OF THE INVENTION

The foldable ironing board proposed by the invention solves the drawbacks set forth above, since not only does it allow drastically reducing its dimensions with regard to the conventional art, but rather it also allows substantially reducing said dimensions with regard to length, such that the longitudinal height of the ironing board in an inoperative state approaches a value which is half of the longitudinal height of the working platform in an operative state, therefore the dimensions of the storage space used for that purpose can be considerably smaller, practically half of those required for conventional boards.
Therefore, and more specifically, the working platform is fragmented into three hinged sectors, an intermediate and majority sector, and two end sectors folding over the upper face of said intermediate sector through hinging means limiting the degree of swing between this limit position of folding over the central sector and another stable limit position in which the other three sectors of the platform are coplanar.
Complementarily and according to another feature of the invention, the support structure, materialized in a "scissor"-type structure, as is conventional, connected to the lower face of the platform, as is also conventional, but specifically to the intermediate sector thereof, presents the particularity that each one of its legs is fragmented into two hinged spans, which are also susceptible to maintaining two limit positions with a stable character, one position in which each end span is laterally and parallelly coupled to the nearest span, corresponding to the folded position, and another position in which it is placed in a position opposite thereto, as an extension of it, in correspondence with the operative state of the ironing board.
Thus, not only is the length of the working platform in the folded position reduced to half, but the length of the support structure folded over the lower face of said platform is also reduced to half.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures described, it can be seen how the ironing board proposed by the invention is constituted of a reliable working platform dimensionally similar to that of a conventional ironing board, but with the special particularity that three hinged sectors are defined therein, an intermediate, majority sector (1) and two end sectors (2) and (3).
In correspondence with the hinged connection edges of said sectors (1), (2) and (3), these incorporate respective centered rectangular notches (4) having a considerable length and limited depth, between which a link (5) is housed, between each sector pair, said link materialized in a "U"-shaped part, especially visible in the detail shown in figure 4, provided on its side branches with a pair of holes (6) intended for allowing the through passage of respective pivot shafts (7), each one of them materialized in an annular rod, especially visible in figure 5, with an orthogonal bending (8) on its ends allowing adaptation of its branch (7) to the lower face of the corresponding sector (1), (2) and (3) to which it is fixed by means of welding, at the same time allowing the ends of said shaft (7) to go through the edge (9) of the metal plates constituting the platform (1), (2) and (3) at a mid-height level of said edge.
Furthermore, each rod incorporates an outwardly projected broad intermediate span (10), opposite to the shaft (7), intended for acting as a stop on the adjacent rod corresponding to the same hinge in the unfolded limit position of the working platform, and as is shown in figure 3, such that said rods (7) not only constitute pivot shafts of each link (5) with regard to sectors (1), (2) and (3) of the working platform, allowing folding of end sectors (2) and (3) over the intermediate sector (1), but rather they also act as unfolding limiting means ensuring that, in the working position shown in figure 1, the three sectors (1), (2) and (3) of the repeatedly mentioned platform are perfectly coplanar with one another and with the upper face of the links (5) occupying the spaces defined by the notches (4).
The conventional scissor-type structure based on two double legs (11-11'), connected to one another at their mid-area by means of a transverse pivot shaft (12), are hinge-connected to the lower face of the intermediate sector (1) of the working platform, one pair of legs (11) being hinge-connected to the lower face of the platform, whereas the other double leg (11') is connected through a sliding runner with locking means, which are not shown in the drawings as they are entirely conventional, the features of the invention, with regard to the support structure, being focused on the fact that both pairs of legs (11-11') are fragmented into two spans hinge-connected to one another, such that the pair of legs (11) extends into an end span (13), whereas the pair of legs (11') extends into another end span (13'), all of them connected by means of a transverse connecting rod (14) near their free end and suitably welded to said elements.
For the hinged connection between the first span (11-11') and the second span (13-13') of each leg, a hinging part (15), shown in detail in figures 10 and 11, has been provided, adopting a grooved configuration, having a "U"-shaped section, one side branch (16) of which is provided with an internal inflection (17) at the level of its entrance opening, determining a restriction of said entrance opening, keeping the spans (11) and (13) of the corresponding leg stable, in the unfolded position for said spans shown in figure 6, as well as in the folded position shown in figure 7. This hinging part (15) is logically provided with a hole (18) centered on each one of its side branches for passage of the corresponding pivot shaft.
According to this structure and from a position of the ironing board such as that shown in figure 12, which provides the user with a working platform having conventional dimensions and an also conventional working height, the board is susceptible to drastically reducing the length of its working platform, as shown in figure 13, and, after folding its scissor-type support structure, as shown in turn in figure 14, also drastically shortening the length of its legs so that the latter do not project from the already folded working platform, as shown in figure 15, achieving a drastic reduction of the general volume of the ironing board in said folded position.
