Disposition introduced in a brake and parking assembly of system panels for closing openings

Description

5 A new arrangement introduced in a brake and parking assembly for panel systems to close gaps. TECHNICAL FIELD

[001] This utility model relates to an arrangement introduced in a braking and parking assembly for panel systems for closing openings such as boxes, windows, partitions and the like. Said braking and parking assembly includes communicating stabilizing elements for glass panels with simplified and effective construction characteristics that promote controlled sliding and safe parking of the glass panels of closing systems for exposing the opening. HISTORY OF THE TECHNIQUE

[002] It is known that conventional window closing systems include a set of brakes and parking mechanisms for the glass panels, and that this set is made up of communicating parts that allow the panels to be parked, especially when articulated to open the windows.

[003] The parking element of the assembly generally consists of a U-shaped plastic piece whose side walls develop a perpendicular laminar projection that forms a central channel for the passage of the structure coupled to the glass panel, and which may include a set of semicircular recesses distributed along the length of the laminar projection, designed to accommodate the brake body. These parking elements are generally mounted at one end of upper and lower intermediate profiles, which in turn are mounted on base profiles belonging to the span closure systems.

[004] The aforementioned brake, in turn, is comprised of a piece of oblong, circular or other similar shape in whose central portion is mounted a support shaft for the pulleys which also integrates, at one end, a plate for fixing to the profiles of the glass panels.

[005] It happens that during the sliding of the panels to open the gap, the engagement between the brake and parking brake can cause the panels to tilt, an effect known as 'panel drop', mainly because they do not provide stabilizing means of Petition 870210112041, dated 02 / 12 / 2021, page 7 / 25 / 5 opening and closing, a fact that can generate vibrations in the panels, as well as, during use, causing damage to the system parts and generating misalignments of the panels, in addition to the need for periodic maintenance, a fact that implies costs for the purchaser of the system. State of the Art Analysis

[006] Research conducted in specialized databases revealed documents relating to brake and parking assemblies for window and door closure systems, such as that presented in document no. BR 20.2014.0153743, which deals with a parking profile for balcony glazing, consisting of a rectangular body provided on its upper face with two small cylindrical elevations and two small holes for fixing screws, one of its ends has a circular pointed protrusion, while its other end has an opening with the same shape as the protrusion to allow connection of the profiles, the inner wall of the profile has curved inlets from which the flange extends.

[007] Document no. BR 10.2019.021286-1 presents a glazing system for closing balconies, verandas, and other openings in residences, commercial establishments, and, mainly, buildings; said glazing system comprises U-shaped cross-section rail profiles with inverted 'L' shaped upper ends where longitudinal slots are provided for mounting brush profiles, while on the inner faces of each side wall of the same profile, orthogonal walls are projected to compose rails for the sliding of the pulley and rails for mounting the stops and parking profiles that receive the pivot brake; juxtaposed to the rail profiles are installed the bed profiles with a central recess for mounting the edges of the glass panels.

[008] Thus, it is a fact that the documents cited in the paragraphs above, despite belonging to the same field of application, do not present any of the characteristics of the object now improved, thus guaranteeing that it meets the legal requirements for patentability. FUNCTIONAL IMPROVEMENTS Petition 870210112041, dated 02 / 12 / 2021, page 8 / 25 / 5 One of the functional improvements of the present utility model consists in the fact that the brake and parking assembly includes communicating stabilizing elements that enable the stable and vibration-free sliding of the glass panels, as well as effective parking, eliminating the risk of the 'falling' effect of the panels and, consequently, avoiding constant maintenance to the other parts of the system. Advantages Obtained

[009] One of the advantages is that the brake stabilizer element that makes up the assembly consists of end tabs shaped to match the receiving channels provided in the parking lot, thus enabling the safe installation of the glass panels.

[010] Another advantage relates to the fact that the parking lot integrated into the complex features a new construction that enables savings in raw materials for manufacturing the part, a fact that brings financial advantages to the manufacturer.

[011] Another advantage of the brake and parking assembly is that the new configuration of both eliminates the need to include additional parts such as retainers, guide plates or panel guides for stabilization, which, in addition to saving money on sales, facilitates the assembly of the glazing system for openings.
