    The terminal device connectable to an air flow opening (14) has a frame portion (10) and gripping means which are slidable into the flow opening to be attached to the wall of the flow opening. The wall of the flow opening may be the wall of a ventilation duct or the wall of a duct collar defining the opening. The gripping means includes a first locking tongue (22) and a second locking tongue (22) with a mounting surface (34) adjustable to the inner surface of the flow opening. The locking tongues can be placed in a first formation where they are at a first distance from one another and in a second formation where they are at a second distance from each other. The second distance is greater than the first distance. Since the locking tongues are placed in the first formation, they can be fitted into the flow opening simultaneously. When the locking tabs are in the flow opening, they can be placed in the second formation where their mounting surfaces are positioned against the inner surface of the flow opening and attach the terminal device to the flow opening. The gripping means may also be more than two in number.

    A terminal to be connected to the air flow port and a method for connecting the terminal to the air flow port
    The invention relates to a terminal device to be connected to an air flow opening, which has a wall and which has a body part and gripping means extending into the flow opening 5 for attaching to the wall of the flow opening. The invention further relates to a method for connecting a terminal to an air flow port.
    In mechanical ventilation, air is led into and out of the rooms via ventilation ducts. A terminal device, such as a valve or diffuser, is provided at the ends of the ventilation ducts which open into the rooms, controlling the amount and / or direction of the airflow to and from the room. A duct collar may be mounted at the end of the ventilation duct to which the terminal is attached. The ends of the ventilation ducts usually open to the ceiling of the room or to the top of the wall. For high-mounted terminals, it is important that the terminal is securely held in place at the end of the vent pipe. The importance of reliable attachment 15 is particularly emphasized in ceiling mounted terminals.
    There are several different options for attaching terminals. The terminal may have a short tube extending inside the duct collar and having threads on its outer surface. Such a terminal can be reliably secured to a duct collar having threads compatible with the terminal threads. However, many of the collars of the channel20 are smooth on the inside, so that threaded terminals cannot be attached to them. The outer surface of the tube extending into the duct collar of the terminal may also have an annular seal which is pressed firmly against the inner surface of the duct collar when installed in the terminal. The mere fitting of the terminal device based on the friction of the compressed seal is unreliable, especially in ceiling mounted terminals. The terminal may also have sharp-pointed projections arranged to press against the inner surface of the duct collar or vent pipe. However, the adhesion of such projections is uncertain. Further, it is possible to attach the terminal device to the ceiling or wall surface surrounding the vent pipe orifice by screw mounting. Screw mounting is particularly difficult when the wall or ceiling surrounding the vent pipe is made of concrete or gypsum board cladding, which is not backed by a sturdy base on which to fasten the screws.
    It is an object of the invention to provide a ventilation terminal and a method for connecting a terminal to an air flow port which can significantly reduce the problems associated with the mounting of known terminals.

    The objects of the invention are achieved by means of a terminal device and method for connection to an air flow port, which are characterized in the independent claims. Certain preferred embodiments of the invention are set forth in the dependent claims.
    The invention relates to a terminal device to be connected to an air flow opening, the terminal having a wall and having a body part and engaging means extending into the flow opening for attachment to the wall of the flow opening. The air flow opening may be an open end of the ventilation duct, an open end of a pipe or duct branching from the ventilation duct, or a hole in a wall or ceiling through which air is designed to flow. The wall of the flow opening may be the wall of the ventilation duct, the wall of the duct collar defining the opening, or the surface of the material layer of the roof or wall structure. The engaging means comprise a first locking tongue and a second locking tongue, the locking tongues having an attachment surface to be placed against the inner surface of the air flow opening. The first and second locking tongues are adjustable in an en15 first configuration, wherein the first and second locking tongues are at a first distance from each other and a second configuration wherein the first and second locking tongues are at a second distance from each other. The second distance is greater than the first distance.
    When the locking tongues are in the first configuration, they can be fitted simultaneously through the open end of the flow opening into the flow opening. Once the locking tongues are inside the flow port, they can be moved to another formation, whereby their mounting surfaces are positioned against the inner surface of the air flow port, securing the terminal to the flow port. When there are only two gripping members, their mounting surfaces are positioned against the inner surfaces 25 on opposite sides of the flow opening. In the terminal device, which is connected to the end of a circular ventilation duct, the diameter of the ventilation duct passes through both mounting surfaces.
    The terminal may be a supply air valve, an exhaust air valve or a diffuser. If the valves or diffusers consist of interconnected, easily removable and reattachable parts, the terminal may be part of one of the aforementioned valves or diffusers.
    Further, the terminal device may be a separate attachment piece to be connected to the airflow orifice, with attachment means for attaching the valve or diffuser.
    In a preferred embodiment of the terminal device according to the invention, the engaging means further comprises a third locking tongue such that the first, second 35 and third locking tongues can be inserted into a first configuration where
    20185549 prh 19 -06-2018 the first, second and third locking triangle circuits have a first length, and a second embodiment wherein the first, second, and third locking triangle circuits have a second length, the second length being greater than the first length. In the second embodiment, the distance between the first, second and third locking tongues may be substantially equal. In this case, the locking surfaces of the locking tongues inserted into the circular airflow aperture rest on the third points of the circuit of the inner surface of the airflow aperture wall.
    In another preferred embodiment of the terminal device of the invention, the engaging means further comprises a fourth locking tongue such that the first, second, third, and fourth locking tongues are insertable in a first configuration having a first length in a polygon circumscribed by first, second, third, and fourth locking tongues , the circuit of the polygon 15 delimited by the second, third and fourth locking tongues has a second length, which second length is greater than the first length.
    In the second embodiment, the mutual distance between the first, second, third and fourth locking tongues may be substantially equal. In this case, the locking surfaces of the locking tongues inserted into the circular airflow aperture rest on the quarter points of the inner surface of the airflow aperture wall.
    In a third preferred embodiment of the terminal device according to the invention, the at least one locking tongue is immobile with respect to the body part of the terminal device. The stationary locking tongue may be an integral part of the terminal body. Preferably, at least one second locking tongue is movable relative to the body of the terminal.
    In yet another preferred embodiment of the terminal device according to the invention, said locking tongue is arranged in a fastening element which is fixed to the body part of the terminal device. Thus, in this embodiment, the fastening member is a separate part which is fixed to the body part of the terminal. Preferably, at least one fastening member is fixedly fixed to the body of the terminal.
    In yet another preferred embodiment of the terminal device according to the invention, the at least one fastening member is hinged to the body portion of the terminal device so that the fastening member is pivotable to a first position and locking tongues to a first configuration. Preferably, the fastening member is lockable in another 35 position.
    20185549 prh 19 -06- 2018
    In another preferred embodiment of the terminal device of the invention, the attachment surface has a design substantially corresponding to the shape of the inner surface of the flow opening wall and / or a friction enhancing surface such as a roughening or a saw blade pattern. Alternatively or additionally, the mating surface of the locking tongue may have a resilient matex layer. The elastic matte layer may contain rubber, neoprene, plastic, polyurethane or silicone.
    In yet another preferred embodiment of the terminal device according to the invention, there is an adhesive layer on the fixing surface of the locking tongue or on the surface of the flexible material layer. Alternatively or additionally, the locking tongue may be magnetic or the locking tongue 10 may be at least partially magnetic.
    In yet another preferred embodiment of the terminal device of the invention, the locking tongue has a support part for supporting and / or supporting the device to be inserted into the ventilation duct.
    The invention further relates to a method for connecting the terminal device to an airflow 15 in an opening having a wall having a body part and engaging means extending into the flow opening for attachment to the wall of the flow opening. The method comprises placing the engaging means in a first formation where the engaging means are at a first distance from each other, fitting the engaging means within the flow opening, and engaging the engaging means within a second formation having the engaging means at a second distance greater than the first distance. In another embodiment, the engaging means are positioned against the inner surface of the flow opening wall, securing the terminal to the flow opening. Preferably, the method incorporates a terminal as described above or a preferred embodiment thereof into an air flow port.
    An advantage of the invention is that it allows the terminal devices to be fixed to the flow openings of different surface finishes on the wall. The invention thus increases the suitability of the terminal devices for different applications.
    A further advantage of the invention is that it allows easy and reliable attachment of the terminal to objects where the screw attachment of the terminal is difficult due to the hardness or softness of the wall surrounding the flow port.
    The invention will now be described in detail. Reference is made to the accompanying drawings, in which:
    20185549 prh 19 -06- 2018 Figures 1a and 1b illustrate a top view of a portion of a terminal device according to the invention, Figure 2 illustrating an advantageous straightening embodiment of a terminal device according to the invention, Figures 3a, 3b and 3c illustrate 4a and 4b are cross-sectional views illustrating the connection of a terminal to a flow port according to the method of the invention.
    Figures 1a and 1b show, by way of example, a top plan view of a terminal device 10 according to the invention. In the following, both pictures are explained simultaneously. The terminal device has a circular plate-shaped body 10 with a circular flow hole 12 in the center. The body shown in the figures only forms part of the actual terminal device, which may be an inlet valve, an exhaust valve or a so-called. a diffuser for controlling the amount of air flowing through the terminal 15 and / or directing the air flow in the desired direction. The body comprises three elongated mounting holes 30 to which parts not shown in the terminal are attached. The terminal is intended to be installed in the air flow opening 14 so that the flow opening 12 of the body part 10 and the air flow opening are aligned (the flow opening is not part of the invention). The flow port may be an open end of a ventilation duct or pipe 20 or a hole through a wall or ceiling of a building through which air is arranged to flow. The flow port has a tubular wall 16 which defines the cross-sectional shape and cross-sectional area of the flow port. 1a and 1b, the flow opening is surrounded by a channel collar whose wall forms the wall of the flow opening.
    Three fastening members are attached to the body 10; a first securing member 18a, a second securing member 18b, and a third securing member 18c. The fastening members have an elongated plate-like base 20 and a locking tongue 22 which pivots substantially directly from the plane of the base, and the tip 28 of the locking tongue folds substantially straight at an angle so that the tip and the socket diverges from the locking tongue 30. The fastening members are disposed substantially equidistant around the hole 12 such that their first surface of the socket rests against the first surface of the body member and the locking tongues extend through the hole 12 into the flow opening, i.e. the space defined by the flow opening wall 16. The first and second fastening means 18a, 18b are fixedly attached to the body 10 by two rivets 24 extending
    20185549 prh 19 -06-2018 through the holes drilled at the ends of the socket and at their positions from the first side of the socket to the other side of the socket. The third securing member 18c is secured to the body member by a rivet 24 only at the first end of the socket so that the third securing member can pivot in a plane defined by the body member around the rivet.
    The base of the third mounting member has a pivoting lever 38 for changing the position of the mounting member.
    1a, the third attachment member 18c is pivoted to a first position where the other end of the socket is within the area delimited by the flow hole 12 in the body. In Fig. 1a, the locking tongues of the fastening members are in a first configuration, where the triangle delimited by the locking tongues has a first length which is smaller than the flow aperture circuit. The locking tongues in the first configuration can thus be fitted inside the flow port.
    In Fig. 1b, the third mounting member 18c is rotated to a second position where its base 15 rests substantially entirely on the first surface of the body member and the locking tongue is moved toward the flow opening wall 16. At the other end of the base 20 of the third fastening member 18c there is a first fastening hole 26a and the body part has a second fastening hole 26b which are aligned when the third locking member is rotated to the second position according to Fig. 1b. The third securing member 20 is locked in the position shown in Fig. 1b by installing a through screw or rivet in the aligning securing holes 26a, 26b. In Fig. 1b, the locking tongues are positioned in a second formation, in which the circle of the triangle delimited by the locking tongues has a second length greater than the first.
    Fig. 2 shows, by way of example, a terminal device 25 according to the invention, illustrated from below. In Fig. 2, the terminal is shown in its entirety, whereby it comprises a body part 10 and plate-like pieces arranged on the first side of the body part. The farthest plate from the body is a closed plate, but there is a hole in the middle for the air to flow through, between the furthest body and the body. Air can thus flow into the flow hole of the body portion 30 between the plate parts. The terminal may be made wholly or partly of plastic and / or metal.
    The other surface of the body member has a hexagonal support plate 32 having a hole the same size as the flow hole 12 in the center. Every other edge of the support plate is folded at an angle to point away from the plane of the body. The round edge of the body member is shaped as a border that rotates around the mouth of one face of the body member.
    20185549 prh 19 -06-2018 so that the free edge of the border and the tips of the folded edge sides of the support plate are substantially aligned.
    The locking tongues 22 extend through the flow hole 12 of the body portion 10 to one side of the body portion. The furthest surfaces of the locking tongues are fastening surfaces 34 provided with a resilient material layer 36. The resilient material layer may comprise, for example, rubber, neoprene, plastic, polyurethane or silicone. The thickness of the flexible material layer may be 1-4 mm, preferably 2-3 mm. When the terminal is secured in place to the flow opening, the resilient material layer on the mounting surface presses against the inner surface of the flow opening wall and is slightly compressed. The terminal is held in place by the frictional force applied between the surface of the material layer and the wall of the flow opening in the flow opening.
    The tongues 28 of the locking tongues are aligned substantially and pointing towards the imaginary central axis through the flow hole. The tips serve as a support member for supporting a device, such as a flow controller or silencer, to be located in the air flow opening or in an extension duct. Folding the locking tongue tips at an angle from the locking tongue level is not necessary to lock the terminal into the flow port, so locking tongues can also be implemented without angled folding tips, especially when no separate devices need to be inserted inside the flow channel.
    Figures 3a, 3b and 3c illustrate, by way of example, some preferred embodiments of a terminal device according to the invention. The pictures show the terminal device viewed from above. In the figures only the body part and the fastening elements attached to it are shown in the figures. In each image, the leftmost view shows the terminal in a situation where the locking tongues 22 in the fastening members are in a first configuration, and the rightmost one shows a situation where the locking tongues are in a second configuration.
    In the embodiment of the terminal shown in Fig. 3a, there are two fastening members, the first fastening member 18a being fixedly attached to the body part and the second fastening member 18b hingedly rotating about the fastening thread. The fastening means are located on opposite sides of the flow hole 12 of the body 10.
    In the embodiment of the terminal shown in Fig. 3b, there are three fastening members, two of which are fixedly attached to the body and one is pivotable about the fastener. The distance between the permanently secured fastening members 18a, 18b is less than the distance between the fixedly fastened and hingedly fastened fastening member 18c
    20185549 prh 19 -06- 2018 distance. This arrangement of the mounting means provides additional working space for the installation of the terminal.
    In the embodiment of the terminal shown in Fig. 3c, there are four fastening members, two of which are fixedly attached to the body and two are pivotally rotated about the fastener. The distance between the fixedly secured fastening members 18a, 18b and the hingedly fastened fastening members 18c, 18d is less than the distance between the fixedly fastened and hingedly fastened fastening member. The use of four mounting means can increase the frictional force holding the terminal.
    Figures 4a and 4b are cross-sectional views showing the connection of the terminal to the air flow port 14 by the method of the invention. The terminal shown in the figures comprises two fastening members, the first fastening member 18a being fixedly fixed to the terminal body part 10 and the second fastening member 18b hinged as described above. For the sake of clarity, only the body portion 10 and the fastening means 18a, 18b of the terminal device 15 are shown. In the following, both pictures are explained simultaneously.
    In Figures 4a and 4b, the flow opening consists of a metal duct collar molded onto a concrete ceiling or wall. The threaded tubular wall portion of the duct collar forms the flow port wall 16. When the terminal is fastened 20, the second fastening member 18b is rotated to a first position where the position of the locking tabs 22 of the fastening members is substantially smaller than the diameter of the flow port. The terminal body 10 is then positioned over the flow opening such that the housing engages with a wall or ceiling surface surrounding the flow opening, both locking tongues engaging the flow opening, and a layer of material in the locking tongue of the first closure member is pressed against the inner surface of the flow opening wall. The second fastening member is then rotated to a second position where the material layer 36 on the fastening surface of its locking tongue is pressed against the inner surface of the flow opening wall. Finally, the second fastening member is locked in this position by the fastening screw as described above. This ensures that the body is securely positioned in front of the flow port. Finally, the other parts not shown in the terminal image are mounted in place on the body, after which the installation is completed.
    Terminals with three, four, or more than four locking tongues are connected to the flow port in the same manner as described above.
    20185549 prh 19 -06- 2018
    In the preferred embodiments of the invention described above, the flow opening comprises a metal duct collar molded into a concrete ceiling or wall. The flow opening need not necessarily have a duct collar, but the flow opening may be a hole in a wall or ceiling cladding plate or an opening in a brick wall 5. The flow orifice need not be circular in shape, but may be, for example, oval or polygonal. In a rectangular flow port, the terminal can be secured with two locking tongues, whose mounting surfaces press against the opposite surfaces of the flow port wall.
    In the foregoing description, the locking tongues are hingedly attached to the terminal body in a planar shape. The terminal portion of the terminal may also comprise a tubular portion which extends into the flow passage when the terminal is installed in the flow port. In such terminals, the locking tongues may be hingedly attached to the inner surface of the tubular portion of the terminal.
    In the preferred embodiments of the invention described above, the engaging surfaces of the locking tongues have a resilient material layer which is pressed against the inner surface of the flow opening wall when the terminal is fixed in place in the flow opening. The terminal is then held in place by the frictional force acting between the surface of the mateural layer and the wall of the flow port in the flow port. The surface of the flow channel of the flexible material layer facing the wall may have a design or profiling substantially corresponding to the shape of the inner surface of the flow channel wall.
    It is further possible that, instead of or in addition to the elastic layer, the fastening surfaces of the locking tongues have a design or profiling substantially corresponding to the shape of the inner surface of the wall of the flow channel to be fastened. The locking tongue mounting surface 25 may also have a surface shape, such as a roughening or a saw edge pattern, which increases friction between the mounting surface and the flow opening wall. This prevents the need for a friction-enhancing elastic layer on the fixing surface of the locking tongue.
    The locking tongues may also be attached to the wall of the flow opening at least partially by an adhesive layer. The adhesive layer may be provided either directly on the mounting surface 30 of the locking tongue or on the surface of the flexible layer in the locking tongue. The adhesive layer may be in place in the locking tongue, covered with a film preventing the adhesive from drying, whereby the film is removed from the adhesive surface when the terminal is attached.
    Further, it is possible that the locking tongue, and in particular its fixing surface, has a magnet or the locking tongue itself is at least partly magnetic. The magnetic locking tongue adheres well to the steel duct collar or open vent in the ventilation duct.
    Some of the preferred embodiments of the terminal device and method according to the invention have been described above. The invention is not limited to the solutions described above, but the inventive idea may be applied in various ways within the scope of the claims.
