    Terminal ventilation device and method of forming an air chamber for the terminal ventilation device.
    The invention relates to a terminal ventilation device and a method of forming an air chamber for the terminal ventilation device.
    Air-supply device structures are known in the state of the art in which, in cross-section of the air supply device, a circular air supply chamber comprises a connected terminal box, wherein said body with circular cross section can be placed. The fresh supply air is led from the outside by a system of ducts into and from the air supply chamber, into an exhaust air chamber portion, and then through a surface of air discharge, in a room. The structures take up a lot of space in all processing stages of the elaboration, because the air supply chamber is quite deep (about 50 cm).
    In the present application, it has been realized how to form the air chamber of the air supply or discharge device in a structure such that the measurement of the cross section of one of its ends is smaller than that of the other extremity. Thus, in cross-section, the cone-shaped structure extends towards one of its ends and is preferably a box-like structure with the shape of a truncated cone. The structure mentioned above has the advantage that said structural components can be stored one on the other, by which they are nested and their need for total space is significantly reduced. The handling costs of the air supply terminal device are therefore lower than those of the state of the art structures, because less factory area is required.
    The invention also relates to a method of forming an air chamber, for a terminal ventilation device. It has been conceived according to the invention to make the air chamber from a single sheet blank, which is taken directly from a rolling mill. The invention proposes how to form the cutting lines of the blank, so that to prepare a conical air chamber, the terminal cutting lines are curved, whereby one of these curved cutting lines is tangential to a side edge of the blank. sheet roll. By forming the structure in this way, the amount of discarded pieces will be as small as possible. Significant savings are achieved.
    The terminal ventilation device and the method of forming an air chamber for a ventilation terminal device according to the invention are characterized by the features presented in the claims.
    In the following, the invention will be described with reference to certain advantageous embodiments of the invention, which are shown in the figures of the accompanying drawings, but there is no intention to restrict the invention only to those this.
    Fig. 1A is an axonometric view of a terminal air supply device according to the invention.
    Fig. 1B is a cross-sectional view along line I-I of Fig. 1A.
    Figure 2 shows the basic idea according to the invention of stacking the air supply chambers one on the other using the conical shape.
    Figure 3 is a developing view of a chamber blank.
    FIG. 1A shows a terminal ventilation device according to the invention, as a terminal air supply device 10. FIG. 1B is a cross-sectional view along line I-I of FIG. As shown in FIGS. 1A and 1B, the air supply terminal device 10 comprises an air supply chamber 11, having the shape of a truncated cone and in which the cross sectional area of the inlet end Ai of the air supply chamber 11 is smaller than the cross-sectional area of the discharge end A2. The inlet end Ai and the discharge end A2 are of circular cross section. The discharge end A2 also comprises a terminal box 12, which can be removably connected, to the air supply chamber 11 to the air of fastener M. The terminal box 12 is of cross-section circular. Terminal box 12 includes an air discharge surface 12a, through which air can be conducted into a room / from a room. The discharge surface 12a may be a perforated surface / fixed louvers / air permeable fabric, etc. In the embodiment shown in the figure, the removable connection assembly 13 for the flow of air Li in the air chamber 11 is connected to one face of the structure. The casing 11a of the air chamber is made of another Garlic blank and comprises a welded joint. The end plate D is connected to one end of the housing 11a.
    FIG. 1A also shows, in broken lines, an alternative way of placing a connection assembly 13 on one end of the air supply chamber 11. The connection assembly 13 can be removably connected to the air supply chamber 11.
    FIG. 2 shows how the conical air supply chamber structures 11 are stacked and interlock into one another to form together a compact stack structure 100. Said nested stack is made possible by the conical shape of the air supply chamber 11 of the body structure. The air supply chamber 11 has the shape of a truncated cone. One end of the body structure 11 has a smaller cross-sectional measurement A 1 than the other end A2, and the housing of the chamber 11 conically extends towards its mouth portion. The structure of the chamber 11 can be handled separately during transport and at the factory. The chambers 11 can be stacked to fit one into the water and the terminal box 12 and the connection assembly 13 can be separately connected by releasably securing means to the chamber structure 11, by example in place of the installation. Such an embodiment is also possible, where the terminal box 12 is in a structure integrated in the chamber structure 11. The chamber 11 has the shape of a truncated cone, which widens preferably towards its part of mouth. Such a structure is also possible when the chamber narrows slightly towards its mouth portion. A small angle of conicity is sufficient to allow the stacking of the chambers 11 for nesting into one another.
    Figure 3 shows a method of preparing an air chamber, which is circular in cross section and has the shape of a truncated cone. Figure 3 shows the cutting lines F1, F2, F3, F4. The metallic material is taken from a roll K, and the air chamber blank is cut along the line F4. Since the chamber is conical, the cutting lines Fl and F2 are curved lines, the line Fl joins the corner end B1 of the blank Ail and at its other end, it joins the other corner end B2. The line F2 is the central zone, tangential to an edge E1 of the strip of the material and joins the terminal cutting lines F3 and F4. In this way, the number of discarded pieces C1, C2 and C3 will be as small as possible. In the center of the garlic blank, a hole is made to join a pipe connection to the relevant place of the inner tube, and said cut is indicated by a line F4 in dashed lines. The cut circular plate D is used to form an end of the air chamber. Only three pieces to throw Cl, C2 and C3 remain of the blank Garlic.
    The air chamber 11 formed with the shape of a truncated cone, is composed of a Garlic blank and it comprises only a weld during the preparation of the housing of the chamber 11. An edge SI is bent on the blank Ail the along a bending line flexed Tl.
