Abstract

CONSTRUCTIVE ARRANGEMENT INTRODUCED IN A SUPPORT FOR SLIDING-WINDOW GLASS PLATE ARTICULATION AND POSITIONING where the plastic support (1a) used inside the metal rail (T) where the glass plates (V) of windows of run, it incorporates a step (4a) in its central channel (4), to make the passage of the shoulder (14) of the triple roller (2) better directed, when it slides along the rail (T) and when it is inserted in said support (1a) to be coupled to the hinge pins (9a). These pins (9a) are now incorporated into the central channel (4) and are cylindrical, thus eliminating drilling and additional elements and simplifying the assembly and also the support mold (1a), providing greater security and efficiency in the system of rotation for the shoulder of the triple pulley

Description

“CONSTRUCTIVE ARRANGEMENT IN SUPPORT FOR SLIDING WINDOW GLASS BOARD JOINTING AND POSITIONING” This descriptive report refers to a utility model patent application for a plastic holder for the interior use of the metal rail where they are mounted and the sliding glass panes are hinged.

Along its central channel of its laminar body, the plastic support incorporates a step that will facilitate and guide the insertion and passage of the triple pulley upper shoulder when mounting onto the rail holding the glass plate.

This support, still in its central channel, incorporates circular articulation pins, which will facilitate and safer the movement of the glass plate for opening and closing the sliding window.

STATE OF THE ART The applicant in this case is the holder of an application for a patent entitled “PLASTIC SUPPORT AND ROLDANA TRIPLA, WITH ARRANGEMENT AND POSITIONING OF SLIDING GLASS PLATE”, in which a laminar plastic holder has constructivity such that it can be screwed into the stop end of the sliding window rail with glass plates. The support has constructive means (pins in its central channel) so that the triple sheave that supports the glass plate and that runs through the rail, is coupled and hinged for opening or closing, without occurring the "locks" hitherto normally occurred in such windows. to run.

It turns out that the center channel of the bracket by itself may not effectively guide the gutter pulley shoulder when it slides down the rail toward the coupled pivot pins.

The pivot pins coupled in the central channel (for the triple-pulley shoulder turning), of course, besides being additional elements in the support, have the rectangular shape with rounded edges, requiring greater complexity of the mold. Furthermore, said hinge pins, by being coupled, rotate together with the triple pulley shoulder, which may compromise the hinge for opening and closing of the sliding window glass plates.

PATENT OBJECT The plastic carrier in question, which is the subject of this utility patent application, is now incorporating a step in its central channel to make the triple-pulley shoulder passage more direct as it slides down the rail and is inserted into said bracket to be coupled to the pivot pins.

The pivot pins are now incorporated into the center channel and are cylindrical, thus eliminating drilling and elements. simplifying assembly as well as the mold, giving greater safety and effectiveness in the turning system for the triple pulley cam. Figure 1, below, shows the state of the art cited above. The images were extracted from this request already deposited by the author of the request in question: Figure 1 - shows, on the left side, the plastic support (1) and its constructivity. As noted, the pivot pins (9) are additional elements and have rectangular shape with rounded corners (11). The figure below shows the end of the rail (T), where the support (1) will be fixed by the pivot pins (9). The rail (T) also has a cutout (R) through which the double guide pulley (20) works. Below the plastic support (1) is aligned the triple pulley (2). In its “head” the triple pulley (2) has superior oval shoulder (14), basically composed of two parallel lateral columns (18), distanced from each other by forming an internal passage (19). In the right-hand side figure, in the enlarged detail is shown the plastic support (1) already fixed to the rail (T) and, by its constructivity, the articulation of the glass plate (P) by the triple pulley (2).

The figures below refer to the constructive arrangement introduced in the plastic holder, reason for this utility model patent application: Figure 2 - perspective view, from the central channel of the holder. As noted, the central channel incorporates a step to better direct the incoming shoulder of the triple pulley. The pivot pins (receivers of the triple pulley shoulder passageway) are cylindrical and already incorporated from the inner surface of the central channel of said support;

In accordance with the accompanying drawings, the “CONSTRUCTIVE ARRANGEMENT INTRODUCED IN SUPPORT FOR SLIDING GLASS PLATE JOINTING AND POSITIONING”, the subject of this utility model patent application, deals with an improvement in plastic support (1) applied inside the metal rail (T) where the sliding window glass plates (V) are mounted and hinged, as shown in the prior art views of figure 1.

As a novelty, the plastic support (1a) receives in its central channel (4) along the side walls (3) an embedded step (4a) between the juxtaposed semicircular sections (5) with its vertical teeth (6) . In the central channel (4), from its inner surface, cylindrical pins (9a) are incorporated, as shown in figures 2 and 3.

With such conformation for the support (1a), the step (4a) of the central channel (4) aligns the oval shoulder (14) of the end of the pulley shaft (13) in the triple (2), as shown in Figure 6. The step (4a) will facilitate steering when sliding said shoulder (14) inside the rail (T), as shown 7A.

After sliding and steering facilitated by the inner passage (19) of its shoulder (14), the triple pulley (2) engages the cylindrical pins (9a), as shown 7B.

After coupling, the triple pulley (2) can be rotated by its passage (19) through the cylindrical pivot pin (9a), as shown 7C and 7D, when opening and closing the sliding glass pane.

Due to the proposed constructivity, the step (4a) gives more precision to the direction of the cam (14) of the triple pulley (2) inside the central channel (4) of the support (la).

By being incorporated, the cylindrical pins (9a) are no longer additional parts, making the support design (la) less expensive, avoiding holes in the central channel (4) of its laminar body and simplifying the mold design.

In addition, the incorporated cylindrical pin (9a) provides a better turning with the opening (19) of the triple pulley (2), giving more security, also without "locks" when opening the glass plate (V) of the window. run.
