Abstract

PLASTIC SUPPORT AND TRIPLE PULLEY, WITH ARRANGEMENT FOR SLIDING WINDOW GLASS PLATE ARTICULATION AND POSITIONING, where a plastic support (1) to be fixed inside the rail (T) receives a movable pin (9), to initially guide the shoulder (14) of the triple pulley (2) of the upper rod (H) for structuring the glass plate (V) of sliding windows. The shoulder (14) has means, in combination with the pin (9), so that when the glass plate (V) is articulated, the initial lock characteristic of this type of sliding window is eliminated. The shoulder (14) of the triple pulley (2), together with the juxtaposed semicircular walls (5) of the channel (4) of the support (1), have means for the glass plate (V), after being opened, to be positioned in varied angles, as the user wishes.

Description

“PLASTIC AND ROLDANA TRIPLA HOLDER WITH ARRANGEMENT FOR PLACEMENT AND PLACEMENT OF SLIDING WINDOW PLATE” This descriptive report refers to a patent application for an assembly formed from the plastic holder which is normally affixed to the interior of the metal rail where the sliding glass panes are mounted and hinged. According to the design, the plastic bracket receives a swivel pin for the coupling of the coincident cut-out of an oval cut-out shoulder, fixed to the triple pulley shaft of the glass upper metal plate.

The moment the glass plate is pivoted, the plastic support pin rotates along with the triple-axle shaft. By misalignment of the pin during rotation a stop is created which prevents any dislocation of the upper metal rod of the glass plate along the longitudinal direction of its rail. Simultaneously, the reciprocating resilience of the triple sheave is kept under strong interference against the curved walls of the plastic support in the inside of the rail, helping to keep the sliding window joint “fair”.

Thus, by preventing the displacement of the glass plate metal rod (usually of heavy weight), its undesirable “locking” inside the upper rail is prevented when the sliding window joint starts, allowing the smooth opening of the sliding window. of user. The oval shoulder of the triple-axle shaft also has vertical strips that coincide with threaded recesses of the curved wall of the plastic interior of the rail, so that, in a ratchet system, each sliding window glass plate, after opening, can be kept locked at various angles.

TECHNICAL STATE

As is well known, glass sliding windows are increasingly used for both practicality and beauty, as they provide the environment, promoting the closure of various masonry spans, such as the balcony opening, integrating them with others. home environments. For example, document MU8300246-4 deposited on 20/02/2003 under the heading "Sliding window arrangements" which calls for a type of sliding glass window using rectangular nylon guides for lower sliding through a rectangular, longitudinal opening into an upper profile. These guideways are compartments with small steel balls where the lower end of the window glass fits in, sliding it centrally and longitudinally through the lower profile of the window frame. window.

In any case, in this case, the sliding window is made up of several glass plates which open and close the masonry gap, being slidable and articulated by their triple pulleys along aluminum rails previously fixed to the wall.

Each glass plate is locked between aluminum rods, one upper rod and one lower rod, which are fitted with a triple sliding pulley and, at a suitable distance, a double opening and closing guide pulley. .

For installation, briefly, each glass plate is inserted by its triple pulley that slides in longitudinal direction of the rail, said glass plates abutting against each other in the open position, delimited under an internal plastic base, previously fixed in a from the ends of the rail. The rail also receives, close to its end point, a cutout of the double guide pulley of each of the glass plates.

For articulation, at the opening and closing steps of each of the glass plates, its triple pulley rotates over the inner plastic base and the guide pulley extends beyond the rail cutout. Therefore, it occurs to the articulation (triple pulley) by the internal plastic base followed by overtaking (by the double guide pulley) by the cutout, which will determine the exit or retraction of the rail glass plate rod, for the opening and closing of the window. sliding glass.

Of course the installation sequence of each glass plate determines the positioning of its double guide pulley so that each one is at the right distance for overtaking by the rail cutout during the opening and closing steps.

It happens that, when articulated by the upper rail, it flattens the glass, by its weight it moves the triple pulley of its pivoting axis on the inner plastic support and, when the double guide pulley overtakes the cut, undesirably runs , briefly running along the longitudinal direction of the rail, causing a "lock" immediately at the beginning of the opening. Throughout the rest of the joint, the glass plate, by its weight, enables the triple pulley to return to its pivoting axis on the plastic support, completing the opening normally.

In order to minimize this effect, it is usually welded, next to the double guide pulley overtaking cutout, a metal “L” plate, whose perpendicular flap is positioned so that the double guide pulley runs through it when overtaking the cutout, in an attempt to prevent undesirable “locking” of the course of the glass rod metal rod by the rail.

Of course, these “L” tabs differ in aesthetics from the design of this type of sliding window, and require welding step and adjustments to guide the double pulley.

PATENT OBJECTIVE

To solve such a problem, the inventor designed the adaptations on the plastic support and also on the top of the triple sheave, through which an innovative technical effect is produced, eliminating the initial pivoting “lock” of the sliding glass pane of glass. . In addition, the glass plate, once opened, can be kept at the desired angle by the user.

In accordance with the accompanying drawings, the “SUPPLY PLASTIC AND ROLDANA TRIPLA WITH ARRANGEMENT ARRANGEMENT AND PLACEMENT OF SLIDING WINDOW PLATE” object of this patent application consists of adaptations made to the plastic support (1 ) and the plastic triple pulley (2) used in the metal rail (T) receiving the upper and lower metal rods (H) which structure sliding glass plates (V). Said plastic support (1) is formed by a laminar plane with side walls (3) delimiting a central channel (4) and juxtaposed semicircular sections (5) incorporating a dentevertical (6). Between these juxtaposed semicircular sections (5) the central channel (4) of the support (1) is hollow through a hole (7) through which the head (8) of a square profile pin (9) with edges (10) is coupled. according to each other by means of rounded corners (11), as shown in figure 1.

When passing the hole (7), the pin (9) is positioned with its edges (10) parallel to the two juxtaposed semicircular sections (5), following the longitudinal direction of the central channel (4) of said plastic support (1). The triple pulley (2), as shown in Figure 2, receives the attachment, at the end of its axis (13), over the top, of an oval shoulder (14) with straight sides (15) and rounded extreme edges (16). ) with vertical, threaded outer recesses (17) extending from its upper wall two parallel side columns (18), spaced apart by forming an internal passageway (19), as shown in Figure 2.

Thus composed the assembly, as shown in figure 3, the plastic support (1) will be screwed to one end of the rail (T), while the triple sheave (2) will be screwed to the end of the upper metal rod (H). structuring of the glass plate (V), also receiving the screwing of the double guide pulley (20), passing through the cutout (R) of the rail (T).

At the time of assembly, as shown in Figure 3, the triple pulley (2) of the upper rod (H) runs through the interior of the rail (T) and through the internal passage (19) of the parallel side columns (18) of its oval shoulder. (14), tightly mates between the edges (10) of the pin (9) of the channel (4) of the support (1), as shown in Figure 4A. In this condition, the oval shoulder (14) is aligned with its sides. (15) to the juxtaposed semicircular sections (5) of the support channel walls (1), completing the coupling of the upper metal rod (H) of the glass plate (V) within the rail (T). Figure 5 shows the sliding window closed when, when hinging one of the glass plates, as shown in figure 6, the double guide pulley (20) overcomes the rail cutout (R) for turning the shoulder. the triple pulley (2) by the pin (8) of the support (1), as shown in figure 7 and its detail C.

At the moment of articulation, as shown in Fig. 8A, opino (7), being coupled to the passage (19) between the parallel side columns (18) of the oval shoulder (14) rotates together, as shown in Fig. 8B and is misaligned. forming a stop in the channel (4) of the support (1). Thus, the metal rod (H) is prevented from moving along the longitudinal direction of the rail (T) when the opening of the glass plate (V) begins, thus avoiding “locking”.

With the articulation, the rounded edges (16) of the oval shoulder (14) are tangent to the walls of the juxtaposed semicircular sections (5) of the channel (4) of the support (1), obtaining a locking at various angles, according to the coincidence of the threaded vertical recesses (17) to the vertical tooth (6), as shown in Figure 8C. This allows the glass plate (V) to be locked in the opening position desired by the user, as shown in figure 9.
