CONNECTORS FOR JOINING PROFILES IN THE CONSTRUCTION OF WINDOWS AND/OR FRAMES SUMMARY

[0001] The present application refers to connecting pieces to join profiles, mullions and transoms or part of the height and part of the width, in the assembly of windows or frames with special characteristics, aimed at the civil construction area.

[0002] Said profiles are cut at 90º and connected to the connectors of the present invention, without the need for machining at the ends of the profiles and with the possibility of adjustments in the dimensions of the profiles in the production and in the place of installation of the frames.

BACKGROUND

[0003] Standard windows and window frames need to be produced at the factory in the exact dimensions for their use.

[0004] After being cut, the profiles need to be machined at their ends to allow their union. The need for machining demands time and special equipment, such as presses and dies, specially manufactured to carry out the machining, which are expensive and require special installations.

[0005] Once machined, profiles cannot be changed in length. Because, if cut again, they lose the machining characteristics that allow them to be joined. This makes it difficult to correct the products during production and adjust them at the time of installation on site, as they do not fit for imperfect windows or windows already built with other measures.

[0006] The use of connecting pieces for joining profiles cut at 90º is already known in the market, as it is already used for joining profiles for counterframe.

[0007] However, these connection pieces for counterframe do not have the characteristics of the object of this patent application, which incorporates in the connectors the necessary machining for the union of the profiles.

[0008] In searches performed, patent application BR2020120143874 was the most relevant representative background. Said patent application refers to a device D comprising an angle that fits under pressure inside profiles A1 D1 C1 B1 with Shape of the profiles A1 D1 C1 B1, being necessary in this model it is necessary to cut the profiles at 45°

[0009] Due to its form and application, however, the object of the patent application in question does not anticipate or suggest the object of this patent application.

DESCRIPTION OF THE INVENTION

[0010] What characterizes the connectors of this order is understood in the fact that parts (part 1 in Figures 2 and 3; and part 2 in Figures 4 and 5) are used for connection to join profiles (assemblies (A, C) and crosspieces (B, D)) in the assembly or manufacture of windows for civil construction.

• - cavidades ou furos(1) que escondem a cabeça do parafuso de ligação, permitindo melhor acabamento;
• - furos(2) para receber parafusos ou rebites para evitar que o conector se desprenda de onde ele se encaixa;
• - abas(3) que melhoram a estanqueidade e evitam que haja passagem de luz no encontro entre o conector e o perfil;
• - cavidades(4) que servem de guias laterais para as folhas quando as mesmas se movimentam sob o trilho da travessa marco;
• - cavidades(5) que permitem o encaixe de trava guia, que limita o movimento de cima para baixo da folha, evitando que a folha se solte do marco;
• - furos(6) que permite o encaixe de parafuso para limitar a movimentação da trava guia mencionado no item anterior;
• - cavidades(7) que permite o encaixe de escovas de vedação;
• - elemento (8) em formato espinha de peixe para facilitar a entrada e dificultar a saída do conector encaixado;
• - abas laterais(9) que dão melhor acabamento e firmeza após o encaixe dos conectores;
• - superfícies (10) em formato curvo que acompanham o desenho do perfil onde o conector é encaixado;
• - conector (11); e
• - montantes (A, C) e travessas (B, D)

[0011] This application comprises the elements identified below, namely:

• - cavities or holes(1) that hide the connection screw head, allowing for a better finish;
• - holes(2) to receive screws or rivets to prevent the connector from coming off where it fits;
• - flaps(3) that improve tightness and prevent the passage of light at the meeting between the connector and the profile;
• - cavities (4) that serve as lateral guides for the sheets when they move under the rail of the frame crosspiece;
• - cavities(5) that allow the fitting of the guide lock, which limits the top-down movement of the sheet, preventing the sheet from coming loose from the frame;
• - holes(6) that allow the insertion of a screw to limit the movement of the guide lock mentioned in the previous item;
• - cavities(7) that allow the fitting of sealing brushes;
• - element (8) in herringbone shape to facilitate the entry and difficult the exit of the fitted connector;
• - side flaps(9) that give better finish and firmness after fitting the connectors;
• - surfaces (10) in curved shape that follow the design of the profile where the connector is fitted;
• - connector (11); and
• - uprights (A, C) and sleepers (B, D)

DESCRIPTION OF THE FIGURES

[0012] The present application comprises a schematic Figure 1 1 with uprights (A, C) and transoms (B, D) and two pieces of connectors (11);

[0013] Figures 2 and 3 refer to one of the connector parts (11) in a top (Figure 2) and internal (Figure 3) view; and

[0014] Figures 4 and 5 refer to one of the connector pieces (11) in a top (Figure 4) and internal (Figure 5).

ADDITIONAL DESCRIPTION

[0015] The object of this application belongs to the field of accessories for mounting windows or similar frames, preferably made of rigid plastic with anti-UV for better weather resistance or semi-rigid, for greater connection and adaptability

[0016] The joining and locking of the connector of the present invention is through connection pieces (plastic), or connectors(11), which fit into the profiles under light pressure and are fixed with or without the use of screws or rivets, the profiles used can comprise profiles different in height and width.

[0017] Still, the union in the assembly process takes place after the said profiles are cut at 90º only, without the need for machining and the use of special equipment for this purpose. After being cut, the profiles can be changed in length, as the machining that was previously carried out on the profiles are in the present invention incorporated in the connecting pieces.

[0018] What the object of this application intends to solve is the possibility of adjusting the length of the product, with the use of connecting pieces. Products cut to standard measures can then be cut again, as the machining (which are at the ends of the profiles) has been transferred to the connecting pieces. Thus, the production of windows allows measurement corrections during the process or can be made with parts produced in standard measurements (simply cut at 90°) and without machining. These parts produced with standard measurements can be fitted to imperfect window openings or already built with other measurements during the installation of the products.

[0019] What characterizes the connectors of this order is understood in the fact that parts (part 1 in Figures 2 and 3; and part 2 in Figures 4 and 5) are used for connecting profiles (assemblies (A, C) and crossmembers (B, D) in the assembly or manufacture of windows for civil construction.
