Description

Field of the Invention

[0001] The present invention relates to ventilation systems of louver systems used for providing natural ventilation at all kinds of openings and doors, wherein vents can be slid into the frame by means of special sliding members without requiring a connection member such as a screw or the like, and wherein finished frames can be mounted to the application opening from outside or inside.

Background of the Invention

[0002] In the state of the art, a louver comprised of fixed vents is formed with the purpose of providing ventilation by arranging vent profiles into a frame comprised of frame profiles on the protrusions externally mounted to the inner surface of the vertical frame profile (e.g.: US3217631), or by arranging the vents into grooves that are formed after the continuous protrusions located in the inner surface of vertical frame profile are milled in conformity with the vent geometry (e.g. US3442744, US3649195), or by arranging the vent profiles into grooves which are milled on the vertical frame profiles in conformity with the vent geometry (e.g. US5255486, US3991533), or by fixing the vents to the vertical frame profile by a screw or rivet coupling (e.g. US3782050).

[0003] When the state of the art is examined, there is a disadvantage of requirement of performing an external operation on the vertical frame profile. For example in the document no. US3217631, which is the state of the art, in order to fix the vent profiles on the frame profile, another part on which the vent profiles can fit should be obtained on the inner surface of the frame profile by either adhering, welding, fixing by screw or rivets another part, or by forming protuberances on the surface of the frame profile by a machine like a press.

[0004] The disadvantage of another state of the art (e.g. US3442744) is that it requires provision of channels, wherein the permanent protrusions on the frame profile to be milled in conformity with the section geometry of the vent profile can be placed, and which will prevent movement of the vent profile; or that it requires, as in the examples of documents no. US5255486 and US3991533, provision of channels conforming with the vent profile geometry on the frame profiles in which channels the vents will be placed.

[0005] The disadvantage of another state of the art (e.g. US3782050) is that it requires all vent profiles used in the louver to be fixed by means of coupling means such as screws or rivets applied from the outer surface of the vertical frame profiles.

Summary of the Invention

[0006] The objective of the present invention is to provide an easy-to-mount louver system, which enables natural ventilation at all openings and doors; can be mounted, differing from the general applications, by sliding the vent profiles into the special geometry frame profiles together with the interconnection parts during the module production; and does not require any auxiliary member or connection member during the said process.

[0007] Another objective of the invention is to allow light passage to a certain extent by means of its special geometry vents and to obstruct visibility of the inner environment from outside.

[0008] A further objective of the invention is to allow use of an insect screen or a bird screen to obstruct entrance of unwanted and harmful organisms to the inner environment.

[0009] Another objective of the invention is to ensure that the connection points at the insect screen or bird screen applications do not deform the aesthetics in the architectural appearance when looked from inside or outside.

Detailed Description of the Invention

[0012] The profiles (1) (2) (3) with a special geometric section in the louver system, which is used for enabling natural ventilation through all openings and doors, are produced in extrusion presses such that they have all required grooves for accessories such as a gasket (5), (8) etc. and connection part (4) and connection profile (3).

[0013] The connection profile (3) or the connection part (4) is used upon preference as the part that is able to perform the same task as the members that carry out connection during mounting of the frame profiles (1) and the vent profiles (2) to each other in production of louver module.

[0014] The connection profile (3) is produced from extrusion profiles of suitable size which will be able to easily move by sliding within the connection part channel (1.2) located on the frame profile (1).

[0015] The connection part (4) is produced by plastic injection or aluminum, steel, zamak etc. production methods in a size that will allow it to easily move by sliding within the connection part channel (1.2) located on the frame profile (1).

[0016] Frame profiles are used as full frame or half frame according to the application type and louver modules are formed (Figure 10, Figure 14).

[0017] The connection part (4), being slid from both sides of the vent profile (3) as seen in Figure 7, is pushed until the connection part stoppers (4.5) (4.9) abut the vent profile (2) and is mounted, such that the upper support (2.1) and the lower support (2.2) located on the vent profile (2) remain within the louver channel (4.10) located between the upper grip (4.1) and the lower grip (4.4) provided on the connection part (4). By means of the stoppers (4.5) and (4.9), the connection part (4) is prevented from being slid on the vent profile (2) more than necessary, and it is automatically positioned at a position ready for being mounted to the frame profile (1).

[0018] When the vent profile (2) is disposed into the connection part vent mounting channel (4.10), the vent pressure protrusion (4.7) located on the connection part (4) pushes the vent profile (2) forward and enables it to fit tightly into the channel. This way, a rigid connection is provided between the connection part (4) and the vent profile (2).

[0019] The vent profiles (2), together with the connection parts (4) provided thereon, are placed into the connection part channel (1.2) provided on the frame profile (1) as seen in Figure 9, and they are positioned upon being slid within this channel.

[0020] When the connection part (4) is mounted to the vent profile (2), the connection part pressure arm (4.2) exerts a pretensioning to the vent profile (2) from its lower surface and thereby enables it to remain in the correct position and prevents it from unnecessary oscillations when it is mounted to the frame profile (1) (Figure 10).

[0021] The vent profile (2) which is positioned on the frame profile (1) is fixed, as seen in Figure 10, by a cylinder head sheet metal screw (6) such that the end of the screw passes through the point where the connection part groove for screw (4.6) and the vent profile lower support (2.2) are connected.

[0022] The other vent profiles are also mounted with the same method, as shown in Figure 10, by being slid together with the connection parts (4) thereon in the groove (1.2) provided on the frame profile such that the connection part lower support (4.4) fits onto the connection part upper support (4.3) of the vent which is previously mounted.

[0023] Since the vent profiles (2), together with the connection parts (4) thereon, are mounted to the frame profiles (1), and the connection parts (4) are successively arranged one after the other in the mounting channel (1.2) provided on the frame profile, mounting position of the vent profiles (2) is automatically determined and an equal and fixed opening is formed between each vent profile as seen in Figure 10. After all the vents are mounted, the louver is completed.

[0024] If a module is to be formed from a full frame using the frame profile (1), the frame profile (1) is cut by a 45° angle, and by means of a corner part (10) as seen in Figure 19, three separate frame profiles (1) are screwed to each other and thereby a "U"-shaped frame is formed.

[0025] The vent profiles (2), together with the connection parts (4) provided thereon, are placed into the connection part channel (1.2) provided on the frame profile (1) as seen in Figure 12, and they are positioned upon being slid within this channel.

[0026] The other vent profiles are also mounted with the same method as shown in Figure 13, by being slid such that the connection part lower support (4.4) fits onto the connection part upper support (4.3) of the vent which is previously mounted. After all the vents are mounted, the last frame profile (1), which is cut by 45° as shown in Figure 13, is screwed by means of the corner part (10) to the U-shaped frame prepared previously and thus production of the louver module is completed (Figure 14).

[0027] The assembled louver module is placed in the opening that it will be used at doors or wall passages as in Figure 15, and the frame profile (1) is fixed to the sub-frame or door profile (12) from the screw mounting surface (1.3) thereon using a cylinder head cross recessed sheet metal screw (7).

[0028] The louver system allows insect screen or bird screen application. The insect screen or bird screen (9) is arranged as in Figure 16 on the frame profile of the louver whose module assembly is completed. The insect screen gasket (8) is placed into the insect screen gasket groove (1.5) provided on the frame profile as in Figure 17, such that the insect screen (9) is fixed between the frame profile (1) and the insect screen gasket (8). The sealing gasket (5) is placed into the sealing gasket groove (1.4) on the frame profile and thereby the joint gap between the insect screen (9) and the frame profile (1) is closed and assembly is completed.
