The present invention relates to an air vent assembly structure that is unlikely to cause troubles.

  Among the air inlets used for air conditioning applications, the grill-type inlet provided as a part of the so-called system ceiling is the space in the ceiling relative to the open-frame grill facing the indoor space. In general, it is common to provide a shielding plate that does not allow the interior space of the ceiling to be seen from the indoor side at a predetermined height position above the grill.

  When installing the grille and the shield plate, long screw bolts (dimension bolts) that are passed through the holes in the shield plate and fixed to the shield plate by tightening the nuts are fixed to the holes in the fixing bracket that is integrated with the grille in advance. It was also fixed to the grill side by tightening the nut through the nut, and the grill and the shielding plate were connected. Among the members that make up the suction port, the grill is delivered to the site separately from the shielding plate and bolt, and is combined with the shielding plate and bolt at the site, and is fixed and integrated while adjusting the distance from the shielding plate. It was. In the grill, the fixing bracket is fixed so as to protrude above the grill, and the fixing bracket is transported to the site in a state of protruding and used. An example of such a conventional grill-type suction port is shown in FIG. FIG. 4 is a longitudinal sectional view and a partially omitted bottom view of a conventional suction port.

  The conventional suction port 100 shown in FIG. 4 is configured to include a rectangular frame-shaped grill 101, a plurality of bolts and nuts 102, and a shield plate 103 that is a substantially rectangular plate. On the side portion of the grill 101, there are disposed a total of four fixing brackets 104 extending upward and projecting upward from the grill 101.

  The conventional suction port is configured as described above, and the grill 101 is transported to the site in a state where the fixing bracket 104 protrudes upward, so that it protrudes when a load is applied from the outside during transport. There is a problem that a large force is intensively applied to the fixing bracket 104 and the side surface of the grill 101 to which the fixing bracket 104 is attached is likely to be deformed and distorted.

  In addition, since the grill 101 and the shield plate 103 are fixed by the bolts and nuts 102, the number of parts is increased, and the shield plate 103 can be accurately connected while keeping the distance from the grill 101 constant in each part. It was difficult and had the subject that work man-hours increased and took time.

  The present invention has been made to solve the above-mentioned problems. In the transport stage before assembly, the main parts are compact and high in strength without protruding parts, so that troubles during transportation can be avoided, while they are connected during assembly. It is an object of the present invention to provide an air inlet assembly structure in which parts can be easily integrated in an easy form and an assembly operation can be performed efficiently.

In addition, by providing a notch portion and avoiding interference with the side portion of the opening frame body while the column portion is a three-dimensional shape having a substantially L-shaped cross section, the state along the side portion of the opening frame body is set in a sideways state. It can be maintained, and the support is not lifted up and the compactness is not impaired. In addition, the contact part with the opening frame body will increase, such as coming into contact with the two frame sides of the opening frame body in the upright state, increasing the strength and improving the stability in the upright state. There is no need to support it by hand, and the work can be done smoothly.

  Further, in the air inlet assembly structure according to the present invention, if necessary, at least three side end portions in the upright state of the column portion are cut in a longitudinal direction from the end portion to the column portion width direction in the column portion longitudinal direction. One or more parts are divided into end pieces, and among each of the end pieces, the intermediate end piece in the longitudinal direction of the support column is protruded in a substantially step shape in the thickness direction with respect to the other end pieces. A side end engaging portion that can be bent and sandwiched between the intermediate end piece portion and the other end piece portion to form a substantially plate-like body end portion having a predetermined thickness is formed. A substantially plate-like body is disposed between the two strut portions standing in a state where the end portion engages with the side end engaging portion, and at least the strut portion, the upper closing member, the opening frame body, and the substantially plate.

The support plate and the substantially plate-like body are engaged with each other by sandwiching the plurality of end piece portions of the side end engaging portion, and the substantially plate-like body is attached to the opening portion surrounded by the support column portion, the opening frame, and the upper closing member. By attaching and integrating the opening frame body, the column part, the upper closing member, and the substantially plate-like body into a substantially box-like body, the structure is not limited to the structure in which the opening frame body and the upper closing member are connected to stand. Depending on the shape of the substantially plate-like body disposed between the support columns, it can be used as various air vents and chambers, and is excellent in versatility.

  Hereinafter, an air vent assembly structure according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. In this embodiment, an example applied to a suction port is shown. FIG. 1 is a side view and a partially omitted bottom view of a suction port to which an air intake opening assembly structure according to the present embodiment is applied, and FIG. 2 is an explanatory view of a column part standing state in the air intake opening assembly structure according to the present embodiment. It is.

  As shown in each of the drawings, the air vent opening assembly structure according to the present embodiment includes a grill 10 as the square opening frame body, and a substantially rectangular plate-like body having a bent end portion. And the shielding plate 20 as an upper closing member formed by the above structure, the suction port 1 is configured, and a collapsible column portion 30 is provided by being pivotally attached to a side surface in the vicinity of each corner portion of the grill 10. The support 30 has a configuration in which the tip portion is engaged with a bent portion around the shielding plate 20 and integrated in a standing state.

  The grill 10 is a rectangular frame-like body that is a room-side portion of the air inlet as a part of the system ceiling, and has a known configuration including lattice-shaped rectifying blades 11 at the opening. Is omitted. A support column 30 is attached to the upright side surface of the grill 10.

  The shielding plate 20 is a substantially flat plate-like body in which each end side portion is bent at a right angle by a predetermined width and is erected, and is formed at an engagement position of the bent portion 21 with the column portion 30 in each corner portion. Is a structure in which two holes 22 are formed.

  The support column 30 has a substantially L-shaped cross-sectional shape, is pivotally mounted on the side surface of the grill 10 and is disposed so as to be tiltable within a predetermined angle range, and is shielded by a tip portion opposite to the pivoted side. The bent portion 21 of the plate 20 is connected to and integrated with two of the side surfaces of the bent portion 21, and the state of standing vertically with respect to the grill 10 and the whole are parallel to the continuous frame sides of the grill 10. It is a mechanism that can be switched to the sideways state.

  At the tip of the support column 30, two incisions having a predetermined length are formed from the end toward the shaft-attached portion, and the end pieces 31 a, 31 b, and 31 c are divided into three in the width direction of the support column 30. Among them, the intermediate end piece portion 31b in the width direction is bent in a state of projecting in a substantially step shape in the thickness direction with respect to the other end piece portions 31a and 31c, and the intermediate end piece portion 31b and the other end piece portion The engaging portion 31 is formed so that the standing portion of the shielding plate 20 can be clamped between 31a and 31c. Further, the end piece portions 31a and 31c of the engaging portion 31 are respectively formed with convex portions 32 that can be fitted into the holes 22 of the shielding plate 20 in the engaged state.

  On the other hand, in the vicinity of the axially attached portion of the support column 30 to the grill 10, a portion that does not follow the side of the grill 10 of the support column 30 having a substantially L-shaped cross section is avoided to interfere with the corner portion of the grill 10. A notch portion 33 is provided, and is a mechanism that fits in a position along the upper side from the side of the side portion of the grill 10 without interference or the like in the lying state.

  Next, the installation process of the suction inlet which applied the air-control opening assembly structure based on the said structure is demonstrated. As a premise, it is assumed that the column 30 is attached to the side of the grill 10 in advance at the factory, packed in a state of being laid sideways on the side of the grill 10, and shipped separately from the shielding plate 20.

  The column 30 is transported to the installation site of the suction port while being laid down and is carried into the site. Since it is in a compact state in which there is no protruding portion from the grill 10 during transportation, troubles such as deformation hardly occur even if an external force is applied due to shaking during transportation.

  At the site, an operator raises the support column 30 to stand. Since the column portion 30 has a notch portion, there is no interference between the side portion of the grill 10 and the column portion 30, and a state in which the column portion 30 stands up substantially at right angles without shaking is obtained. Further, the upright support column 30 comes into contact with the two frame sides of the grill 10 to be in a reliable self-supporting state, and it is not necessary for the operator to support the support post portion 30 by hand after the upright support.

  The shield plate 20 is positioned above the upright support column 30, the bent portions 21 of the end of the shield plate 20 are sandwiched between the engagement portions 31, the shield plate 20 is pressed evenly from above, and the tip of the support column 30 is When the protrusion 32 is pushed into the hole 22 of the shielding plate 20, the engagement at the engaging portion 31 is established, and the grill 10 and the shielding plate 20 are integrally connected via the support column 30. In this connection, there is no need for any connecting members such as bolts and nuts, and the interval between the shield plate 20 and the grill 10 that are integrally connected is constant by the support column 30, and adjustment of the interval is also unnecessary. Thereafter, the operator completes the installation work by mounting and fixing the integrated grill 10 and the shielding plate 20 on the support member 70 forming the system ceiling.

  As described above, in the air restriction port assembly structure according to the present embodiment, the collapsible support column 30 that can be erected as necessary is integrally disposed near the corner portion of the grill 10 that forms part of the suction port 1. Since the grill 10 and the shielding plate 20 are connected to each other via the support column 30 that is raised with respect to the grill 10, the support member 30 is placed in a sideways state along the side of the grill 10 before the assembly. The strength at the time of delivery can be increased while making it compact, making it difficult to cause deformation of the grill 10 due to external force, and at the time of assembly, the column part 30 can be raised as it is, and the shielding plate 20 can be attached to the end part, The labor for adjusting the distance between the shielding plate 20 and the grill 10 can be saved, and the number of parts can be reduced to reduce the work man-hours, thereby shortening the work time on the site and reducing the cost.

  In the air inlet assembly structure according to the above-described embodiment, the space between the support columns 30 is open as a portion through which air sucked from the opening in the grill 10 passes. As shown in FIG. 3, at the side end portion of the support column 30 in the standing state, like the engagement portion 31, a plurality of cuts from the side end portion in the width direction of the support column portion 30 are formed and divided into at least three in the vertical direction. Among the end piece portions 34a, 34b, 34c, the end piece portion 34b at the middle position in the vertical direction is bent so as to project in a substantially step shape in the thickness direction with respect to the other end piece portions 34a, 34c. The end piece 34b and the other end pieces 34a, 34c form a side end engaging portion 34 that can sandwich the thin plate-like substantially plate-like end portion, and at each corner portion of the opening frame 40 An end portion of the substantially plate-like body 50 between the support post portions 30 is the side end engaging portion. 4 and can be configured to obtain a state in which the column 30, the upper closing member 60, the opening frame 40 and the substantially plate-like body 50 are integrated in a substantially box shape, If the entire structure is an airtight structure, it can be applied as an air-conditioning outlet or chamber for air conditioning, providing versatility while ensuring compactness during transportation and resistance to deformation. In this case, the upper closing member 60 may be provided with a neck portion or the like for connecting a duct and may be partially open.

  Further, in the air vent assembly structure according to the above-described embodiment, the engagement between the support column 30 and the shielding plate 20 is established by fitting the convex portion 32 of the support column 30 and the hole 22 of the shielding plate 20. However, the present invention is not limited to this, and in the case of increasing the connection strength associated with the engagement, a female screw hole is provided instead of the convex portion of the support column 30, and a screw passed through the hole 22 of the shielding plate 20 is screwed into the female screw hole. The shield plate 20 and the column 30 may be screwed together.
