Definitions
- the present invention relates to a ventilation duct or tube, which is mainly used in buildings for the transfer of hot or cold air (or for heating or cooling, respectively), and for other applications where there is a need for circulation of air or liquids.
- a traditional canal or pipe system is usually assembled before being delivered to the installation site so that they can be quickly installed without any additional collection step. Nevertheless, this means that such a system of channels is bulky and voluminous and, therefore, difficulties arise with its transportation. This leads to an increase in prices for such a system of channels.
- the aim of the present invention is to eliminate or substantially reduce the disadvantages of the above mentioned duct systems and provide a ventilation duct or pipeline that has the desired aspects, namely, which is easy to receive, store, transport and prepare for installation and which at the same time has high performance characteristics.
- the channel is usually not limited to the amount of flat folding / unfolding, i.e. upon receipt, it would have sufficient strength without breaking the tightness at the bending / extension points.
- a seamless ventilation duct that comprises a plurality of elongated panels and a fully formed hinge joint between said panels, wherein the duct is coextruded and comprises forming regions for joining the panels from another, more flexible material, compared to the material of said extruded panels, allowing relative movement between the panels around the indicated areas of the swivel so that the channel could It is difficult to transport and / or store.
- SUBSTITUTE SHEET (RULE 26) Each panel, preferably located essentially at right angles to two adjacent panels, when the channel is laid out.
- each panel is rigid or semi-rigid and forms one side channel wall.
- each side wall is essentially in contact with another side wall.
- the channel is mainly made of filled or unfilled plastic, which is known from the prior art and is commercially available, which may additionally contain a plasticizer, flame retardant, a color agent, a UV protector, an antibacterial agent, and other additional useful or necessary additives to the plastic, which are known from the prior art.
- the plastic may be a homopolymer or copolymer or a ternary copolymer, in particular such as, for example: polymer: polystyrene, polypropylene; copolymer: butadiene styrene, polyvinyl chloride (PVC); ternary copolymer: acrylonitrile butadiene styrene (ABS).
- thermoplastic used can be used to form an effective joint; or thermoplastic elastomer with the corresponding physical properties, such as elasticity.
- the channel is predominantly coextruded.
- other methods of preparation such as parallel injection molding or blow molding, which are known to those skilled in the art.
- the present invention also provides a method for producing a seamless extruded ventilation duct, which comprises a plurality of elongated panels and a fully formed hinge joint between said panels, wherein the duct is formed by coextrusion and comprises forming regions for joining the panels from
- SUBSTITUTE SHEET (RULE 26) another more flexible material compared to the material of said extruded panels, which includes the stages of coextrusion or parallel injection molding or blow molding, cooling the channel and bending the channel in the corresponding articulated joints for folding it, intended for its transportation or storage, or folding it for installation.
- the channel may be coextruded or formed in an unfolded or partially unfolded state. However, the channel may alternatively be coextruded in a flat state and then expanded for installation.
- Figure 1 illustrates a side view of a ventilation duct shown in a fully unfolded state in accordance with the present invention
- Figure 2 illustrates an enlarged partial projection of a portion of the ventilation duct shown in Figure 1;
- Figure 3 illustrates a side view of the ventilation duct shown in Figure 1, but in a folded state
- Figure 4 illustrates an enlarged partial projection of a portion of the ventilation duct shown in Figure 3;
- Figure 5 illustrates a photograph of a ventilation duct, in accordance with the present invention, in the folded state and the unfolded state.
- FIG. 1 shows a side projection of a rectangular ventilation duct or pipe 1 in accordance with the present invention, which comprises parallel first and second main walls 2, 3, separated from one of the first and second minor walls 4, 5, where walls 2, 3, 4, 5 together form
- each of the swivel joints 6 is made of a material that differs mainly in the physical characteristics of the material, such as the elasticity and flexibility of the material, from the material that is selected to form the walls of channel 1, which makes the channel more flexible in this area / In other words, when channel 1 is formed by coextrusion, the surface of the joint 8 and the surface of the connection 9 to the surface of the walls are formed.
- planar planar surfaces of walls 2, 3, 4, 5 themselves have less flexibility, thus they are rigid or semi-rigid, i.e. . Don't bend so easily.
- channel 1 is shown in the illustrated embodiment, is generally rectangular in cross section, it may also be square in cross section, in which case each of walls 2, 3, 4, 5 has the same height.
- Channel 1 formed by walls 2, 3, 4, 5 and swivel 6, coextruded as a pipe, which consists of a discrete element and, mainly, in the form in which it is shown in Figure 1, namely, in its fully unfolded state, in which the main walls 2, 3 and minor walls 4, 5 are located at right angles with respect to one to one.
- it can also be coextruded in a partially folded state.
- channel 1 is illustrated in a fully folded or folded-flat state in which the main wall 2
- SUBSTITUTE SHEET (RULE 26) and the non-main wall 4 overlap the main wall 3 and the non-main wall 5.
- Folding of the channel 1 is achieved by applying a shear force to the channel in the direction of the arrow “X” or the opposite direction of the arrow “X”, sufficient for folding by bending the channel around the hinges 6.
- FIG. 4 an enlarged projection of the articulated joint region 6 between the main wall 2 and the non-main wall 4 and between the non-main wall 4 and the main wall 3 is illustrated.
- the angle between these two walls 3 and 4 was essentially reduced to zero so that the front surfaces of these walls 3 and 4 are now in effect in contact.
- the swivel 6 now takes the form of a generally hemispherical protrusion due to the inverse elastic deformation of the material when the channel 1 is in the folded state.
- the channel contains a working wall 8 of the swivel joint 6 and two walls of the joint 9.
- the working wall 8 can change the surface conformations, and the side walls can extend from the working wall 8 at an angle of 90 degrees or any other angle.
- channel 1 when channel 1 is coextruded, it can be folded from the unfolded state shown in FIG. 1, in the folded state shown in FIG. 3, due to the flexibility in the field of swivel 6 of channel 1, for, in fact, reducing the size and, in fact, simplifying storage and transportation.
- channel 1 is made of plastics that can be easily coextruded.
- the predominant materials are polypropylene, PVC or ABS, as any thermoplastic or thermoplastic elastomer with
- SUBSTITUTE SHEET (RULE 26) appropriate physical properties to produce an effective swivel.
- the material of the channel 1 and, in particular, the flexible section of the channel 1 in the swivel joint 6 of the channel is capable of bending / unbending many times, without breaks, in order to fold and unfold the channel 1 for storage, transportation and installation.
- the material of the swivel joint 6 will maintain a degree of rigidity, despite the fact that it has been bent / unbent many times, and thus, the channel 1 will be in its unfolded state without folding under the action of its own mass.
- this invention provides a ventilation duct that can be easily obtained, easily folded, and easily decomposed. Since the channel is completely formed as a discrete element, there are no additional components for its installation, and no additional special tools are needed. Therefore, the obtained channel is cheaper, and the installation is easier, maintaining tightness in the area of the swivel 6. In addition, since the channel is seamless, there is no need to connect two walls when the channel is laid out. This is an important aspect of the channel according to the present invention, since there is no need for connection methods, such as welding, riveting or gluing and others that are used for installation on site.
