  The air vent 100 shown in FIGS. 7 and 8 is installed in a blowout duct (box) 103 facing an opening 102 provided in the ceiling board 101, and is housed in the blowout duct 103. And a louver face (hereinafter referred to as a face) 105 disposed at the lower end of the main body. Reference numeral 106 denotes a louver. A device such as a shutter that opens and closes manually or electrically is provided on the upper portion of the main body 104, and the face 105 is detachably screwed to the main body 104 for maintenance or cleaning.

  Brackets 107 having female screws are attached to the inner surfaces of the upper four corners of the main body 104, and screws 109 are inserted from below into a bracket 108 provided with a screw insertion hole (a hole or long hole) provided in the face 105. The face 105 is attached to the main body 104 by being screwed into the female screw. A flange 110 (gasket receptacle) that extends outward is provided at the lower end of the face 105, and a gasket 111 is interposed between the flange 110 and the ceiling board 101. In order to make the pressing pressure of the gasket appropriate, there is a gap between the brackets 107 and 108. The gasket 111 also serves as a seal between the main body 104 and the ceiling board 101 and extends to the outside of the flange 112 at the lower end of the main body.

Seikiguchi 100 as described above, attached to generally ceiling and wall regardless, if attached to the ceiling after laying the ceiling board 101, and an opening 102 is provided on the top warts over de The air vent 100 is attached, and then the final finish painting of the ceiling board 101 is performed. Therefore face 105 Remove before painting, can not be painted until the four corners to be mounted again after the coating operation end. That is, as described above, since the face suspension is fastened by the four screws 109, the portion where the inner surface of the face is in contact with the ceiling board 101 cannot be painted unless the face 105 is once removed before painting. Further, it is necessary to temporarily attach the face 105 once removed at the preliminary inspection stage, which is troublesome twice. In addition, there is a problem that the ceiling is high to leave a great deal of work loss is risky operation industry.

  Patent Document 1 discloses a shutter unit in which a shutter and a filter are integrated and a face is attached to the front surface. This is convenient for cleaning ducts and chambers because the filter unit can be attached to and detached from the frame with the face attached. The problem of attachment / detachment is not solved. Further, Patent Document 2 discloses a wall-embedded air control opening in which a face can be easily attached to and detached from a main body using a so-called roller catch. However, this is also uneasy to use as a ceiling-embedded air vent, and handling of the removed face is troublesome.

  On the other hand, Patent Document 3 discloses a unit mounting structure in which an elongated ceiling outlet is suspended by two springs. This has the advantage that the face can be attached regardless of the shape of the chamber and the mounting bracket, but it is not intended to facilitate attachment / detachment. Patent Document 4 discloses an air outlet of a type in which a blowing guide is engaged and fixed to the back side of a ceiling board by a biasing force of a pair of leaf springs. This thing cannot be attached stably, and it is difficult to place the removed blowing guide.

  The present invention provides a ceiling-embedded air control opening that can easily attach and detach the face to the main body at the time of the above-mentioned finish painting or temporary inspection, and does not trouble the place of the removed face. It is said.

Control air port of the present invention (claim 1) comprises a body mounted so as to close the opening formed in the ceiling board, and a face to be attached to the lower surface side of the body, the face is out of the lower end An air vent having a flange that expands in a direction and contacts the lower surface of the main body and the lower surface of the ceiling board via a gasket , wherein the face is in contact with the lower surface of the main body and is spaced downward from the lower surface of the main body It is attached to the main body via a support member that suspends and supports the face in a state where it can move between and away from the bottom, and the face is held in contact with the lower surface of the main body. comprises holding means for said support member, extending vertically from one of the body or face, the hanging member composed of a plurality of elongated bolts or rods having a locking portion on the end portion The bracket is provided on the other side, is inserted through the hanging tool so as to be movable up and down, and has a hole that engages with the locking portion, and the hanging tool is at least diagonal among the four corners of the main body or the face. provided at two positions, the holding means, and a magnet provided on one of the body or face, provided on the other, characterized Rukoto such from the magnetic member is attracted to the magnet.

In such Seiki port, the louver comprising a plurality of wind direction plates therein are provided in the face, the hanger is extended to the body or we vertically downward, the lower end of the sling, the When the face is attached to the main body, the position is such that it does not interfere with the louver, and the lower end of the suspender has a shape that can be rotated from the gap of the louver so that the upper end of the suspender is screwed to the main body. shall locking portion is provided is preferable (claim 2). Further, a louver made up of a number of wind direction plates is provided inside the face, and an engaging portion that engages a hole in the bracket is fixed to the upper end of the suspension, and a magnetic nut is screwed to the lower end of the suspension. The lower end of the suspension tool is a position where the engaging portion is engaged with the bracket and suspended so as not to interfere with the louver, and the position where the magnetic nut can be screwed from the gap of the louver. near Ru it is preferable (claim 3).
The method of attaching the air vent of the present invention to the ceiling board is a method of attaching the air vent to the ceiling board using any one of the air vents, and in the opening formed in the ceiling board, Attaching the main body so as to close the opening, adsorbing the flange of the face to the main body via the magnet and the magnetic member, and inserting the lifting tool into the bracket so as to be movable up and down. The face is peeled off against the attracting force of the magnet and the magnetic member, the bracket is engaged with the engaging portion and suspended, and the lower surface of the ceiling board and the flange Finish painting from the gap opened between the ceiling board and the vicinity of the opening of the ceiling board, and when the drying and curing of the painting is completed, the face is lifted and the flange is moved forward. And a step of adsorbing to the main body through the magnet and the magnetic member (claim 4).

  The air vent of the present invention (Claim 1) can be in a state in which the face is separated from the main body, and in this state, it is suspended by a support member. Therefore, if the air vent manufacturer installs the air vent on the ceiling board and holds the face with the support member, it will not interfere with the finish painting when the painter enters, and the paint will be applied to the four corners. it can. Then, after painting, the painter only needs to lift the face and hold the face on the holding means. Therefore, unlike the case where the four corners of the face are fastened to the main body with screws, there is no need for the installation operator to make another business trip after painting.

  Moreover, even if it becomes the schedule of temporary inspection in the suspended state, it can be inspected only by holding it with the holding means. If curing is required after painting, the face can be hung without raising it. In that case, the face is raised later, but since no screw work is required, even an unskilled person such as a sales representative can easily hold the face with the holding means.

Further, the supporting member is provided on the other side, the hanging tool comprising a plurality of long bolts or rods extending in the vertical direction from one of the main body or the face and having a locking portion at the end, vertically movably inserted, and, since a bracket having a hole for engaging with the locking portion, the locking portion of the end portion of the plurality of hangers release the face from the ceiling is engaged to the bracket . Therefore, the face can be stably suspended in a substantially horizontal state by a plurality of suspension tools. When the face is raised, it can be lifted as it is and held by the holding means at the lower part of the main body.
Further, since the holding means is composed of a magnet provided on one of the main body or the face and a magnetic member provided on the other and attracted to the magnet, the face can be firmly held by the attractive force of the magnet. Can be easily installed and removed without tools.

Further, since the hanger is provided at two positions at least the diagonal of the four corners of the body or face, the hanging member of the two portions of the diagonal, it is possible to have hanging well balanced face. When the hanging tool is provided on the diagonal and the screw fastener is provided on the other diagonal, it can be firmly fastened at the two screw fastening portions after finishing the painting of the ceiling board as necessary. Such a screw fastening portion improves safety against earthquakes, particularly when used for a large air vent.

  Next, an embodiment of the air vent of the present invention will be described with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an embodiment of the air control port of the present invention, FIG. 2 is a longitudinal sectional view of the air control port, FIG. 3a is an enlarged view of portion A in FIG. 2, and FIG. FIG. 4A is a cross-sectional view showing a main part of another embodiment of the air-control opening of the present invention, and FIG. 4B is a state in which the face of the air-control opening is suspended. FIG. 5 is a longitudinal sectional view showing another embodiment of the air control port of the present invention, and FIG. 6 is a plan view of the face of the air control port.

  The air vent 10 shown in FIG. 1 includes a main body 11 attached to a ceiling board, a face 12 detachably attached to the main body, a hanger 13 for hanging the face 12 on the main body 11, and a face 12 And a holding member 14 for holding the main body 11. The main body 11 is substantially the same as a conventionally known one, and includes a cylindrical portion 16 that has a rectangular tube shape and a flange 17 that extends outward from the lower end thereof. An L-shaped bracket 18 is fixed to an upper part or an intermediate part of the inner surface of the cylindrical part 16 facing each other by welding or the like. A female screw 19 is formed on the horizontal surface of the bracket 18.

  Normally, a shutter, an opening / closing mechanism, and the like are provided on the upper portion of the main body 11, but are omitted here. The main body 11 can be constituted by, for example, sandwiching a shutter or the like between two metal plates 11a constituting two opposing wall surfaces and spot welding the metal plates 11b constituting the other two wall surfaces. it can. The lower end of each metal plate is bent outward in advance to form a flange 17. If the bracket 18 is spot-welded in advance to the above-described opposing metal plate 11a, the manufacture is easy. As the metal plate, a steel plate attracted by a magnet piece is used. In the case of a non-magnetic material such as a synthetic resin, non-magnetic stainless steel, or aluminum, a magnetic material adsorption portion is provided on the lower surface of the flange 17. Usually, metal is preferable because fire resistance is required.

  The face 12 includes a rectangular tubular portion 21 that is somewhat smaller than the tubular portion of the main body 11 and a flange 22 that extends outward from its lower end. A continuous rising wall 23 is provided on the outer periphery of the flange 22. Similarly to the main body 11, the face 12 can also be manufactured by combining and welding four metal plates. However, since the flange 22 and the rising wall 23 are airtight, it is preferable to join them by welding or the like so that there are no cuts or gaps. The four metal plates are integrally press-formed so as to form part of the cylindrical portion 21, flange 22 and rising wall 23, and these four metal plates are integrated by butt welding or fillet welding. By doing so, the face 12 having high airtightness can be obtained. However, it can also be configured by other manufacturing methods.

  As shown in FIGS. 2 and 3, a louver 24 having a large number of wind direction plates 24 a provided in parallel is provided inside the face 12. The wind direction plate 24a constituting the louver 24 is attached to the cylindrical portion 21 by a shaft 24b so that the angle can be adjusted. Before assembling the face 12, the shaft 24b is inserted with a friction ring for maintaining the angle of the wind direction plate 24a and then passed through a hole formed in the opposing metal plate. 2 and 3, the louver 24 that can adjust the wind direction in one direction is described. However, a louver 24 that has two directions of louvers 24 that are orthogonal to each other and that can adjust the wind direction in the left, right, and front and rear directions is also used. sell.

  As shown in FIG. 1, four L-shaped brackets 25 are fixed to the upper end of the face 12 at positions facing the bracket 18 of the main body 11. A long hole 26 is formed in the horizontal surface of the bracket 25. Out of the four brackets 25, two diagonal brackets 25 are passed through long bolts 27 and their tips are screwed into the female screws 19 of the bracket 18 of the main body. The head 27 a of the long bolt 27 is engaged with the long hole 26 of the bracket 25 of the face 12, whereby the face 12 is suspended from the main body 11. The length of the long bolt 27 is set such that the head 27 a does not interfere with the louver 24.

  A square annular gasket 28 is accommodated in the flange 22 of the face 12. The gasket 28 can be made of, for example, a sponge-like foamed resin. Further, a magnet piece 29 is fixed to the center of the upper surface of each side of the flange 22. The magnet piece 29 is disposed at a position facing the flange 17 of the main body 11. The magnet piece 29 can be fixed to the flange 22 with an adhesive or a double-sided tape (see reference numeral 30 in FIG. 3a). When the material of the face 12 is a magnetic material, an attractive force acts between the face 12 and the flange 22. Therefore, the adhesive or double-sided tape may be such that the magnet piece 29 is not displaced.

The attracting force or number of the magnet pieces 29 is set to such an extent that it can be peeled off by hand when the flange 17 of the main body 11 is attracted and the weight of the face 12 can be sufficiently retained, for example, about 1 to 2 kgf. The magnet piece 29 can be provided at the corner portion of the flange 22, but the magnet piece 29 is more easily peeled off by the action of the lever. The number of the magnet pieces 29 is not particularly limited , but is about 4 in the case of the air vent 10 having a substantially square plan view as shown in FIG. 1, and 4 to 6 in the case of a rectangle as shown in FIGS. To the extent.

  Next, with reference to FIGS. 3a and 3b, the method and operation of attaching the air vent 10 to the ceiling will be described. At the factory shipment stage or at the site of installation work, the main body 11 and the face 12 are initially separated. And the opening part 33 is formed in the site | part corresponding to the duct (refer code | symbol 32 of FIG. 2) of the ceiling board 31, and only the main body 11 is attached to the ceiling board 31 like normal construction. Although the flange 17 of the main body 11 is brought into close contact with the lower surface of the ceiling board 31, airtightness is not necessary. Next, the face 12 is brought into contact with the lower surface of the main body 11. At that time, since the magnet piece 29 is attracted to the flange 17 of the main body 11, the face 12 does not fall even if the hand is released. In this state, the long bolt 27 is passed from below the face 12 through the gap of the louver 24, the tip is passed through the long hole 26 of the face bracket 25, and the tip is screwed into the female screw 18 a of the bracket 18 of the main body 11. This results in the state of FIG. Since the long bolt 27 is long, it can be screwed relatively easily even from the gap of the louver 25.

  Subsequently, when the face 12 is pulled downward, the magnet piece 29 is peeled off from the flange 17 of the main body 11. When the face 12 is further lowered, the head 27a of the long bolt 27 is engaged with the bracket 25 of the face 12 and suspended as shown in FIG. In this state, there is a gap 35 between the lower surface of the ceiling board 31 and the flange 22 of the face 12. Therefore, finish painting can be performed up to the vicinity of the opening 33 of the ceiling board 31 during the painting operation. After the painting operation, when the drying and curing of the coating is completed, the face 12 is lifted again to attract the magnet piece 29 to the flange 17 of the main body 11. As a result, the construction is completed again as shown in FIG.

  In the air vent 10 described above, even if the attracting force of the magnet piece 29 decreases due to an earthquake or over time, and the face 12 may fall, the length of the long bolt 27 is dropped. It's safe because you only do it. However, according to the customer's request, etc., it is also possible to perform fastening with the same screws 34 as before using two sets of brackets 18 and 25 not provided with long bolts as shown in FIG.

  When a preliminary inspection schedule is entered before the painting operation, the face 12 may be lifted and adsorbed to the main body 11 as described above. After the preliminary inspection, the face 12 is lowered again in preparation for the painting work. When the face 12 is raised and lowered, the long bolt 27 moves up and down in the long hole 26, thereby providing a guide action and being easy to operate because it does not shift greatly from side to side. Also, it does not require skilled work such as screwing into the female screw through the screw at the tip of the driver from the gap of the louver 24, and even a painter or sales person who is not skilled in such work can easily work. can do. Further, since the face 12 removed from the main body 11 is hung on the lower side of the corresponding main body 11, no place is required, and management is easy even when there are a large number of air vents 10.

  4a and 4b, the air vent 36 is formed with a long hole or a screw insertion hole (so-called fool hole) 37 in both brackets 18 and 25, and the long bolt 27 is passed through the screw insertion hole 37 from above. It is substantially the same as the air control port 36 of FIG. 3A except that the lower end thereof is screwed into the magnetic nut 38 and the magnetic nut is attracted to the lower surface of the bracket 25 of the face.

  In this air vent 36, the lower end of the long bolt 27 is lowered to the vicinity of the louver before the face 12 is attached, so that the tip of the long bolt 27 is inserted into the bracket 25 of the face, or the magnetic nut 38. The work of screwing is easy. After the face 12 is attracted and held on the main body 11 as shown in FIG. 4a, the long bolt 27 is held in the attracted state on the bracket 25 of the face 12 via the magnetic nut 38, so that the long bolt 27 faces upward. There is no possibility that its lower end interferes with the louver of the face 12. Therefore, the long bolt 27 can be lengthened, and the gap (reference numeral 35 in FIG. 4b) between the lower surface of the ceiling board 31 and the flange 22 of the face 12 when the face 12 is suspended can be increased. Therefore, it is easy to perform painting work.

  Instead of the magnetic nut 38, a weld nut welded to the bracket 25 can be used, and a female screw can be directly formed on the bracket 25. However, in that case, the long bolt 27 is screwed into the welding nut or the bracket 25 from the upper side of the main body 11. The bracket 25 can be clamped between two nuts from above and below, but the work becomes complicated.

In the above embodiment, the face 12 is suspended by the two long bolts 27. However, when fastening with the screw 34 in FIG. 2 is not required, the face 12 is suspended by the four long bolts 27. Also good. In FIG. 3a, FIG. 4a, etc., a long bolt 27 having a hexagonal head 27a is used, but a so-called hole bolt (socket bolt) having a hexagonal hole may be used. Instead of the long bolt, rod de provided with engagement members for holes and engage the bracket is good, upper and lower ends with a rod and nut screwed on their male screw having a male thread at each end Do etc., it can also be hung in another suspension member. Also in that case, the upper end of the suspension member may be fixed to the bracket on the main body side, and the lower end may be fixed to the bracket on the face side. Furthermore, it is not necessary to fix both sides. When neither side is fixed, the suspension member is suspended by the upper bracket.

  In the above-described embodiment, the magnet piece 29 that holds the face 12 on the main body 11 is attached to the flange 22 on the face side, but conversely, it can be attached to the flange 17 on the main body side. Further, a magnet piece 29 can be fixed to a part other than the flanges 17 and 22, for example, one of the upper and lower brackets 18 and 25, and the opposite bracket can be adsorbed by the magnet piece. In that case, both the main body 11 and the face 12 can be made of stainless steel that cannot be attracted by the magnet pieces, and only the bracket can be made of a steel plate.

  Moreover, the magnet piece 29 can be attached to other parts such as the upper part of the main body 11 and the face 12 and the side wall part, and a magnetic body to which the magnet piece is attracted can be provided on the other side. Further, the gasket 28 in FIG. 1 may be a packing having a magnet function such as packing of a refrigerator door, and the sealing material may be used as a magnet piece. Furthermore, if the gasket sealability can be maintained, instead of the magnet piece, a holding means such as a so-called roller catch that holds a roller between two curved leaf springs, or a spring action. For example, a combination of an engaging claw snap-coupled with a stepped portion engaged with the engaging claw can be engaged with and held by the receiving member simply by pressing it from one side with a predetermined force, and with a predetermined tensile force. Various holding means capable of releasing the alignment can be employed.
