Detailed Description of the Invention [0019] The examples shown here are intended only to exemplify one of the countless ways of carrying out the invention, however without limiting the scope of it.

Constructive sealing system comprising Bidirectional Displacement Guide System [0020] The present invention comprises a constructive sealing system comprising: fixed frame (1); movable frame (2); rails (3) with bidirectional displacement guide system; glass (4) with sealing system; pivoting caster (5) and uprights (6).

[0021] In particular, the glass (4) with sealing system is fixed on the pillar (s) (6), providing perfect sound tightness.

[0022] In particular, the glass sealing system (4) comprises an elastomer strip.

[0023] In particular, the pivoting caster (5) provides a movement of the movable frame with folding at the end of the stroke at closing.

[0024] In particular, the constructive sealing system of the present invention can be used on windows and / or doors and / or other building elements.

Example 1. Preferential realization [0025] New bidirectional displacement guide system for the sliding window frame. This system allows the manufacture of soundproof sliding windows for use in buildings.

[0026] This system is very simple, economical and efficient. It consists of guide rails fixed at the bottom and top which guide the pivoting casters, which are fixed to the movable frame.

[0027] The fine adjustment in the closing of the frame is made by means of rubber sealing elastomeric cords that are fixed in all the outline of the frame where it is folded and pressed the mobile frame in the closing. This one

Petition 870190066243, of 7/15/2019, p. 13/24

6/11 procedure guarantees perfect sound tightness.

[0028] This bi-directional displacement guide system composed of guide rails and pivoting castors provides easy movement of the movable frame with folding at the end of the course at closing. This hitting at the end of the stroke at the closing adjusts and presses the frame against the sealing elastomer fixed on the frame (upstream) providing a sound seal.

[0029] In the closing process at the end of the course, the guide rails have curvatures that gently fold the movable frame against the marcomontante.

[0030] The pressure and adjustment of the movable frame on the elastomeric rubber seal that is fixed on the riser provides perfect sound tightness.

[0031] There is a line of research developed at the Acoustics Laboratory of this institution that measures the sound insulation performance of construction components. During several researches it was evident the lack of technology in our frames, mainly in the sliding windows, which are the most used in Civil Construction.

[0032] All sliding windows until the present tested date, presented low sound tightness. Never achieving the performance of the glazing used in them.

[0033] This clearly demonstrates the presence of cracks that are responsible for the low performance in sound insulation to aerial noises. The average performance of the sound reduction index Rw of the tested sliding windows is in the order of Rw «20dB (A) well beyond the performance of the glazing.

[0034] Below we show the performance of some traditional sliding windows. It is evident in all results the low rate of sound tightness and consequent mediocre performances.

[0036] In the sliding window prototype developed with this new bidirectional guide system, two types of glazing were used. Initially 4mm glasses and after 8mm glasses.

[0037] Sound insulation tests were performed to aerial noise according to ISO 140-3 and ISO 717-1 in the prototype with 4mm and 8mm glazing, and the results obtained are presented in the graphs below.

[0038] The results of the isolation tests of the prototype prove the perfect sound tightness to aerial noises offered by the new closing system of this sliding window. In the two situations with different glazing, 4mm and 8mm, the sound insulation performance of the glass itself was achieved, which proves the sound seal of the frames and the efficiency of the closing system.

[0039] This new bidirectional displacement guide system bounces the movable frame against the fixed frame at the end of the course at closing. Thus, this frame is pressed against the upright frame creating, with the help of rubber sealing cords, a condition of perfect sound tightness of this window, as demonstrated in the sound insulation tests.

11/11 [0040] With this system, sliding windows become efficient in sound insulation, reaching the performance of the glazing used in them.

[0041] In places with a lot of pollution, we have the possibility to use more insulating glazing, increasing the thickness of the glass or even double glazing, as the frame system remains watertight when closed.

[0042] In addition to the excellent sound performance, we observed the simplicity of this system, which makes it from an economic point of view, extremely competitive in the market.

[0043] It should be noted that any company will be able to implement it, as it does not require any special or sophisticated equipment to execute this type of bi-directional guide system.

[0044] This new system has not undergone durability and fatigue tests to better understand its toughness in real situations, although due to the simplicity of the system, it is believed in its efficiency.

[0045] As it is very simple and cheap, this system can be used in buildings for any social class.

[0046] Those skilled in the art will value the knowledge presented here and will be able to reproduce the invention in the modalities presented and in other variants, covered by the scope of the attached claims.
