Description

SWINGING SLIDING DEVICE DEVICE

OBJECT OF THE INVENTION

The present invention has as an object a sliding leaf device that has a counter-closure that allows the correct folding of the sheets in the position where they fold to free the surface of the enclosure previously occupied.

Due to its special configuration, the counter-closing of the swinging leaf device prevents the pitching of the leaves when the folding starts because it has at least one horizontal surface that retains a coupling means that travels in solidarity with each leaf.

This coupling means is coupled to both upper hinges and lower hinges and travels through the present counter-lock which is arranged in means for guiding the leaves.

BACKGROUND OF THE INVENTION

Swing sliding leaf devices that are guided and supported by an upper guide and a lower guide are known in the state of the art, and where the leaves can rotate about an axis defined by a hinge attached to each leaf.

Swing sliding blades have groups of front and rear bearings that allow the blades to be guided by the upper and lower guides, considering the front bearings those that are closest to the folding end.

Once the leaves reach one of the ends of the vertical enclosure, they can be folded down, being essentially perpendicular to the surface they previously closed, thus occupying a minimum space and leaving almost all the enclosure open and without intermediate profiles that worsen the aesthetic .

In the previous systems there are a set of elements that perform the hinge function of each of the sheets. Among the above is the European patent with publication number EP0610263 that refers to glazing systems that make use of two or more glass cloths capable of sliding down lower and upper guides, where the hinge has a first coupling element and a second coupling element cooperating with each other to allow rotation of each of the sheets of the enclosure when said elements are coupled and prevents said rotation when said elements are uncoupled.

The first coupling element is an essentially rectangular piece that allows said first coupling element to slide inside the second coupling element that is circular in shape with a rectangular central guide which makes when the first coupling element is inside the second coupling element can be carried out the folding of the sheet.

Leaf abatement is possible due to

that rear bearings of the same exit through windows present in the upper and lower guides.

The bearings are guided by grooved guide grooves present in the upper or lower guides. These grooved guide grooves must have tolerances to allow sliding of the bearings without blocking.

When the folding of the blade is carried out, there is a pitch of the same in the area of the front bearings due to the cantilever weight of the blade during the transition at the exit of the rear bearings from the guides to the window, due to There are no grooved guide grooves in that area that support the weight of the blade.

Similarly, the European patent EP10855160 is known where the first coupling element is a circular piece with a cutout that defines a straight section and the second coupling element is a guide with circular recesses so that the first coupling element slides by the second coupling element when the straight section is parallel to the longitudinal direction of the guide of the second coupling element.

When the center of the first coupling element coincides with the center of the circular recesses of the second element, the folding of the sheet can be carried out preventing rotation in the rest of the situations.

However, in this device the

same disadvantages as those cited for the patent EP0610263 due to the fact that a leaf pitch occurs during folding, since the weight is only supported by the friction produced on the curved contact surface defined by the first and second curved sections coupling elements.

All these inconveniences are overcome by the invention, which now proceeds to describe where the pitching of the sheet is avoided during its folding, ensuring a correct exit thereof through the window.

DESCRIPTION OF THE INVENTION

The present invention has as an object a sliding leaf device that has a counter-closure that allows the correct folding of the sheets in the position where they fold to free the surface of the enclosure previously occupied.

The device has a set of sheets that make up the enclosure, where each of the sheets has bearings that allow the displacement of the sheets in the longitudinal direction of the plane of the enclosure.

These bearings are displaced by guiding means present in a profile of the enclosure, each blade having front bearings, which are those closest to the area of abatement and rear bearings.

Also, each of the sheets has a bi

sagra associated with the front bearings that allows the blade to be folded down when it reaches the area of dejection. These hinges can rotate with respect to the bearings in a certain situation.

For this purpose, a coupling means, arranged in a prismatic manner with a cross section that includes at least one circumference segment and at least one straight section, which slides along a countertop arranged in the guiding means when the straight section of said coupling means is parallel to the longitudinal direction of the counter lock.

This counter lock has circular recesses to house each coupling means of each of the enclosure sheets.

When the coupling means is located in the space defined by a circular recess, the folding of the sheet can be carried out preventing rotation in the rest of the situations.

In this situation of despondency, the rear bearings of each blade leave through windows arranged in the upper and lower guides.

The counter closure has at least one upper or lower section whose projection in the direction defined by the hinge intersects the surface of the coupling means in the areas of the counter closure where the folding of the sheets is possible, so that the pitching of the hinge is avoided. sheet due to the contact of said upper or lower section with the coupling means,

since the torque is restricted due to the weight of the blade in

this zone.

In essence, the invention relates to a swinging leaf device according to claim 1.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The object of the request is a swinging leaf device. The document considered closest in the state of the art is D01. Said document D01 describes a device of sliding sliding leaves, where each of the sheets has hinges that carry out the movement of the sheets in the longitudinal direction of an enclosure when said hinges are linked to guiding means and where the hinges they act as an axis to lower the blades with respect to the longitudinal direction of the enclosure (see figure 1), also presenting a coupling means (8), prismatic in shape with a cross section that includes at least one circumference segment (12) and at least one straight section (figures 2, 3), integral with the hinge (4). the coupling means (8) slides along a counter-closure (9) arranged in the guiding means (7) when the straight section of the coupling means (8) is parallel to the longitudinal direction of the counter-closure (9), wherein said counter-closure (9) has circular recesses that allow the folding to be carried out when each of the coupling means (8) is arranged in said circular recesses with at least one straight section of each of the sheets (1) of the enclosure (see figures 2 and 3). In said document D01, the counter-lock (9) has at least one upper section or one lower section whose projection in the direction that defines the axis of rotation of the hinge (4) intersects with the surface of the coupling means (8) when said coupling means (8) is arranged in the circular recesses of the counter-closure (9), thus avoiding the pitching of the sheet (1) due to the contact of said upper or lower section with the coupling means (8). Claim 2: the counter-closure (9) has an upper section and a lower section whose vertical projections fall within the surface of the coupling means (8) in the areas of the counter-closure (9) where the folding of the sheets (1) is possible . Claim 3: The variant contained in claim 3, with two parallel straight sections, is a design alternative with respect to that described in the first claim. It is not justified in the description which is the technical advantage derived from said form with respect to that general in which there is only one straight side. Therefore, it is considered that claim 3 is not inventive since it would be easily deductible for a person skilled in the art from the first form. Claim 4: the counter-closure (9) has two-to-two circular entrances that allow the passage of the coupling means with a quasi-rectangular shape when said coupling means (8) presents its straight sections parallel to the plane of the enclosure and allows the rotation of the means of coupling (8), and consequently, the folding of the leaf (1) when the center of the coupling means (8) with two parallel straight sections coincides with the center of the circular recesses of the counter-closure (9). These characteristics are deduced from D01 without making any inventive effort. Claims 5 to 11: are design variants and joining means known in the state of the art. State of the Art Report Page 4/5  WRITTEN OPINION Application number: 201130616 Claim 12: in D01, in its figure 2, we observe how the sheet that is arranged at the end of the enclosure has a different coupling system, since it only rotates and does not slide along the guide. Claim 13: joining by joining means is trivial. Claim 14: The use of bearings is widely known in the mechanical field. Claim 15: Obviously, if the hinges must drag the leaves, there must be an anchoring means that interconnect For all the foregoing, it is considered that the content of claims 1 to 15 is not inventive in view of the state of the art represented by document D01. All this in accordance with the definition of inventive activity of article 8 of patent law 11/1986. The rest of the documents cited (D02 to D07) are considered a reflection of the state of the art.
