This technical solution relates to the field of ventilation systems equipment, specifically to ceiling linear diffusers made of plasterboard (PBD) and a metal frame.
Linear diffusers are used in suspended ceilings to hide the frame of the ventilation grate and ensure the required distribution of air flows.
Various types of linear diffusers for PBD ceilings are known from prior art. Examples of such solutions are known from ES 1064231 U, U.S. Pat. No. 4,537,347 A, and KR 20130108792 A.
A diffuser manufactured by Redvent (https://redvent.ru/upload/iblock/0e8/0e811da1f8af846eb7aaf32f4f243d76.pdf) can be considered as analogous. The diffuser contains blades that block the air flow passage. A design of two blades fixed to the inner walls of the diffuser is used for each passage. Such a design is unreliable and inefficient, since it does not allow to maximally direct the air flow along the ceiling (approximately 90 degrees), and also such a design does not ensure proper fixation of the blades, which can lead to their displacement under the force of air flows.
The claimed device is aimed at solving a technical problem: creating a new efficient design of a line diffuser, which provides a more efficient and reliable way to fix blades, which in turn allows for more efficient air flow direction.
The technical result is an increase in the efficiency of air flow distribution passing through the diffuser due to the fixation of the blades using brackets on the blades fixation unit.
According to the first preferred embodiment of the claimed solution, a ventilation line diffuser is presented, which is made in the form of two metal profiles connected by a fixing member with a blades fixation unit made in the form of a profile with recesses for blades, wherein blades fixed with brackets, ensuring that the blades are pressed against the profile with the possibility of rotation.
In one particular implementation of the diffuser, the recesses are C-shaped.
In another particular implementation, the blades contain a C-shaped groove for its placement in the recess of the blades fixation unit.
In another particular implementation, the brackets contain a clamp to fix the blade in a C-shaped recess.
In another particular implementation, the profile of the blades fixation unit contains slots for fixing brackets.
In another particular implementation, the brackets are fixed with fasteners to the profile of the blades fixation unit.
In another particular implementation, the profile of the blades fixation unit contains at least one cavity.
In another particular implementation, the brackets are interconnected.
According to the second preferred embodiment of the claimed solution, a ventilation line diffuser is presented, which is made in the form of two metal profiles connected by a fixing member with a blade fixation unit made in the form of a profile with recesses for blades, wherein the blades are fixed with a bracket, ensuring that the blades are pressed against the profile with the possibility of rotation.
In one particular implementation, the recesses for blades are C-shaped.
In another particular implementation, the blades contain a part with a C-shaped recess for its placement in the recesses of the blades fixation unit.
In another particular implementation, the bracket contains a clamp that fixes the blades in a C-shaped recess.
In another particular implementation, the profile of the blades fixation unit contains at least one cavity.
Profiles (10, 11) can be made of various shapes and designs. The profiles (10, 11) are interconnected by a fixing member (12), which is, for example, a rectangular element (hollow or monolithic) made of metal and fixed with fasteners (e. g. self-tapping screws) to the surface of the diffuser profiles (10, 11). Additionally, the profiles (10, 11) may contain a specially made ledge (102, 112) that provides alignment of the fixing member (12), which further increases the rigidity of the diffuser (100). It should be noted that the fixing member (12) can be of any shape (oval, cylindrical, etc.), while maintaining its main functionality in terms of forming the design of the diffuser (100).
The central part of the diffuser (100) contains a blades fixation unit (14), which is attached to the fixing member (12) via fasteners or welding. The unit (14) is a profiled element that can be of various shapes (trapezoidal, pyramidal, etc.). The profile of the unit (14) can be a single integral structure or contain one or more recesses. The blades fixation unit (14) is designed to ensure reliable fastening and rotation of the blades (141, 142), regulating the air flows passing through the diffuser (100).
Blades (141, 142) are articles with two main parts: a part for fixation on the unit (14) with a C-shaped recess; and an elongated, predominantly rectangular part, allowing to direct air flows. The blades (141, 142) are made as a single part and fixed with brackets (144, 145) that press a part of the blades with a C-shaped recess into special made recesses (143) of the unit (14). The recesses (143) are preferably made in a shape that repeats the surface profile of the C-shaped part of the blades (141, 142), ensuring a tight fit of the blades to the unit (14).
The blades (141, 142) are fixed in the recesses (143) using brackets (144, 145), which have a clamping element partially repeating the C-shaped profile of the blades, which allows them to be placed in a C-shaped recess, providing both reliable downforce and variability in the range of movement of the blades (141142), allowing them to be fixed at any point in their movement range (angle α). The extreme movement points of the blades (141, 142) are the surface of the unit (14) and the inner surface of the profiles (10, 11), allowing two main positions (open/closed) of the blades, and also allowing to adjust the speed and volume of the passing air masses through the diffuser (100). Each lamella (141, 142) can be independently and securely fixed at any of the possible points in its range of movement.
As shown in
In one potential embodiment, brackets (144, 145) can be connected to each other via a plate or some other type of rigid connection, which additionally ensures their and blades (141, 142) stable position. Possible brackets embodiments depend on their design features and those of the blades fixation unit.
In one particular embodiment, profiles (10, 11) can be made of a frame structure that consists of three segments, where each segment is a frame with a void inside. The inner area of the void is larger than the area of the outer frame. The segments shape and number may vary.
Thus, when implementing the claimed design of the ventilation diffuser, a more efficient distribution of air flows is ensured due to the reliable fixation of the blades (141, 142) held by brackets (144, 145, 147), which significantly expands the range of their location at various points and increases the fixation reliability. The claimed design of the diffuser (100) is more reliable compared to existing analogs. The claimed design also implements a new solution that has not previously been used in analogous products, which is an innovation in the field of ventilation diffusers.
