Description

SLIDING WINDOW SYSTEM WITH SHEET PERPENDICULAR SHEET

The present invention is framed within the technical field of window closure systems and more specifically within sliding closure systems.

STATE OF THE PREVIOUS TECHNIQUE

Sliding window systems are known from the state of the art. These systems base their tightness on a set of brush-type weatherstrips that are placed between the frame and the leaves and that impede the passage of air. The problem is that the tightness achieved with these systems is quite limited, especially when compared with the tightness offered by swing window systems that close by means of a rubber that is placed between the frame and the sheet and that is compressed in the closing time

The reason for the low tightness offered by sliding closure systems is that some clearance must be maintained between the leaf profiles and the frame so that an effective displacement of said sheets can be made avoiding high friction. The placement of the brushes mentioned above allows the passing air to suffer a loss of load so that the flow of air passing through the clearances is reduced but the effect remains much less efficient than that of the swing window systems where the rubber is compressed and thus guarantees tightness.

Among the sliding window systems that are known in the state of the art, the one described in the patent ES2241456 in which the leaf displacement system is made perpendicular to the plane of the gap is worth mentioning. The leaves of this system maintain a considerable clearance with respect to the frame during most of its movement so that said movement is smooth and easy to perform. The system comprises special pieces placed in the frame and the leaves that make the leaves approach the frame just before closing. In addition, this system includes rubbers instead of brushes, so at the time of closing the rubbers compress against the frame, producing a seal similar to the one in the casement window systems. The problem with this system is that it is very expensive and difficult to manufacture. These problems lie above all in the difficulty of performing the necessary machining.

EXPLANATION OF THE INVENTION

The present invention has as its object a sliding window system with leaf displacement perpendicular to the plane that guarantees the sealing and is simple and economical to manufacture. In this way, the system that is proposed allows to have a tightness like that of the folding systems and with a standard mechanization of the same complexity as the mechanization of the profiles known so far for sliding systems.

Each blade of the present system comprises three profiles that are a side blade profile, a center blade profile and a roulette blade profile. In addition, the system comprises two frame profiles, which are a side frame and a lower upper guide. Likewise, the sliding window system comprises an adjustable wheel system with free displacement in the longitudinal direction of its axis of rotation, a system of diverter parts that is inserted into channels of the lower upper guides and that force the leaves to approach the frame at the time of closing, a system of skates that guide the leaves and serve as a meeting with the diverter pieces and a cremone-like closure system with inclined planes that drag the leaves in the final part of the movement of the closure.

Throughout the description and the claims the word "comprises" and its variants are not intended to exclude other technical characteristics, additives, components or steps. For those skilled in the art, other objects, advantages and features of the invention will be derived partly from the description and partly from the practice of the invention. The following examples and drawings are provided by way of illustration, and are not intended to be limiting of the present invention. In addition, the present invention covers all possible combinations of particular and preferred embodiments indicated herein.

DETAILED EXHIBITION OF MODES OF EMBODIMENT

The sliding window system with leaf displacement perpendicular to the plane described by the present invention comprises, in addition to three leaf profiles and two frame profiles, an adjustable wheel system, a diverter system, a skid system and a system of closing by means of which the hermetic closing of the window is guaranteed. The complete system can be seen in figure 1.

The wheel system (6) allows the displacement of a bearing (10) in the direction of its axis, within a housing (11) that has a clearance for this purpose as seen in Figure 2. This displacement of the bearing ( 10) is the key that allows the sheet (15) to stick to the side frame (4) while still resting on the guide (5). That is, the plane of the set moves in the direction of its perpendicular. The bearing (10) does not move in this direction and this is how the movement of the blade (15) is made compatible to approach the frame with the support of the blade on the rail.

The system of the present invention also comprises parts called skates (8) that are located on the roulette blade profiles (3). When the window is closed, the skates (8) placed in the leaf profiles come into contact with parts called diverters (7) that are located in the side frame (4). When the diverter parts (7) come into contact with the skates (8), they can, due to their geometry, force the sheet (15) to move in the direction perpendicular to its plane. Thus the sheet approaches the lateral frame (4) and the watertight effect is produced with the contact of rubber bands (14) located on the sheet and the frame (4).

The window closure system is cremone type. To end the window closing process, the closing cremone (10) that drags the leaf into its final part of the path must be activated. At that time, the closing blade (12) of the cremone, which consists of an inclined plane, as seen in Figure 5, meets the strike (13) that is located on the side frame (4) and that It also has an inclined plane. As the cremone (9) performs its upward movement to allow the window to close, the sheet (15) approaches the side frame (4) and thanks to the action of the diverter parts (7) and the skates ( 8), the sheet also sticks to the frame (4) perpendicular to its plane, producing the seal.

In summary, the sliding window system with leaf displacement perpendicular to the plane of the invention comprises at least one window leaf (15), with a lateral leaf profile (1), a central leaf profile (2) and a Roulette blade profile (3) and comprises a side frame (4) and an upper-lower guide (5). This invention aims to ensure a tight closure of the window comprising it. It has a wheel system (6) located on the guide (5) with a housing (11) inside of which there are bearings (10) placed loosely so that the bearing (10) can be moved in the direction of its axis. The system also includes skates (8) on the roulette blade profiles (3) and diverter parts (7) located on the guide (5) at the ends that are close to the closure. The contact of the skates (8) with the diverter parts (7) causes the sheet (15) to move in a direction perpendicular to its plane, approaching the side frame (4) in that direction. The system of the invention also comprises a closing cremone (9) with at least one closing blade (12) with an inclined plane, and a strike (13) that also has an inclined plane and is located in the side frame (4 ). The contact of the closing blade (12) with the strike (13) brings the blade closer

(15) to the side frame (4) producing a tight seal.

The most important advantage of this system is that it allows the sealing to be carried out without the need for special machining. Thus, all the elements can be manufactured using the same machining that are normally used in traditional sliding series.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulation of execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The present application is included in the field of sliding windows with airtight seal. The object of the invention, set forth in the first and only claim, relates to a sliding window system with leaf displacement perpendicular to the plane, comprising at least one window leaf, with a side leaf profile, a profile of central blade and a roulette blade profile; It also includes a side frame and an upper-lower guide. The invention is characterized by comprising an adjustable wheel system for the movement of the leaves, and a system of diverting parts with which the approach of the leaves to the frame is forced at the time of closing the window, through a system of skates that allows the guidance of the leaves, complemented with a Cremona type closure. Of the documents found in the search, document D01 can be considered the state of the art closest to the technical object of the first claim. This document also discloses a sliding window system with leaf displacement perpendicular to the plane, with its corresponding side blade profile, center blade profile and roulette blade profile; It also includes side frame and upper-lower guide. Like the application, the invention of document D01 comprises a wheel system located in the guide with a housing, inside which there are bearings that can move laterally in the direction of its axis. The contact of the skates located in the window profile with guides that act as diverter parts, causes the sheet to move in a direction perpendicular to its plane, the window assembly with its profiles approaching the side frame to achieve a closure airtight. The main difference between this document D01 and the application document refers to the existence of a Cremona type closure, with a closing blade and a striker both with inclined planes, cooperating to produce a tight seal. However, in the sector of window closures it is widely known to use this type of closures to promote sealing (for example document D02). Document D02 discloses a Cremona type closure for sliding windows, which includes two elements that act as a closing blade and strike, both with inclined planes, in this case with an inclination of 30 °. It would be obvious to a person skilled in the art, especially when the same result is to be obtained, to apply this characteristic of document D02 with its corresponding effect, to the closing of the sliding window of document D01, so that the same characteristics are obtained as those collected in the first claim. Therefore, according to all the above, it is concluded that the first and only claim of the application would lack inventive activity (Article 8.1 of Law 11/86 of Patents).
