Description

Technical Field

[0001] The present invention relates to an air outlet adjustment unit and a mounting method thereof.

Background Art

[0002] For example, in each facility such as a general house, an office, a store, a hospital, a factory, etc., an air intake is provided on the ceiling for the circulation and adjustment of indoor air. Examples of the air intake include an air outlet and a suction port (exhaust port). The air outlet is for blowing air from an air conditioner or the like into the room through a duct, and the suction port is for sucking indoor air and sending it to an air conditioner or the like through a duct or discharging it to the outside (Patent Document 1).

[0003] Among such air intakes, the air outlet is mainly composed of an air outlet duct hole provided on the ceiling and an outer frame attached to the ceiling with screws along its outer edge. In some cases, a grid is attached inside this outer frame. If there is a person working or the like directly below such an air outlet, the blown air for air conditioning (outlet air) will continuously hit directly, which may affect the person's physical condition or cause discomfort.

[0004] Therefore, conventionally, for example, an air outlet adjustment unit 101 as shown in FIG. 6 is attached to the air outlet. This air outlet adjustment unit 101 has a rectangular parallelepiped shape as a whole. It has a rectangular upper frame portion 102 of a standard size, a bottom plate portion 103, and columnar frame portions 104 connecting the four corners of the upper frame portion 102 and the four corners of the bottom plate portion 103, and these are fixed to each other by screws, welding, etc. and integrated. Thus, except for the bottom plate portion, it is composed of frames along each side of the rectangular parallelepiped. By attaching the upper frame portion 102 to the outer frame of the air outlet, the air outlet adjustment unit 101 is mounted to prevent the outlet air from the air outlet by the bottom plate portion 103 and prevent it from directly blowing directly on a person directly below the air outlet.

[0005] Patent Document 1 Japanese Patent Application Laid-Open No. 2001-208412 Summary of the Invention Problems to be Solved by the Invention

[0006] However, the conventional air outlet adjustment unit 101 as described above has a fixed overall shape. In particular, the shape of the rectangular upper frame portion 102 attached to the air outlet is fixed, and it can only be attached to an air outlet corresponding to the frame shape and frame size. The shapes and sizes of the air outlets in each facility vary, and each time, a dedicated upper frame portion 102 for that air outlet must be prepared. In addition, since the upper frame portion 102 is formed to surround the entire outer frame of the air outlet, the larger the size of the air outlet, the larger the size of the upper frame portion 102 must be, and its weight also increases. If the size and weight increase, naturally, the burden on the operator who installs the air outlet adjustment unit 101 increases, and placing such a heavy object near the ceiling is not preferable in terms of safety.

[0007] The present invention has been made to solve the above problems, and an object thereof is to provide an air outlet adjustment unit and a mounting method thereof that are more adaptable to air outlets of various sizes and shapes than conventional products, are lightweight, and are inexpensive. Means for Solving the Problems

[0008] In order to achieve the above object, the present invention is an air outlet adjustment unit for adjusting the blown air of air-conditioning air from an air outlet, comprising a plurality of brackets that are each separable and attachable to the air outlet, and a buffer member supported by the plurality of brackets, wherein the plurality of brackets each have, an attachment portion attached to the air outlet, a placement portion on which the bottom surface of the buffer member is placed and supported, and an extension portion connecting the attachment portion and the placement portion. The buffer member is detachably placed on the placement portions of the plurality of brackets attached to the air outlet, and is suspended so as to face the air outlet with a space therebetween. Provided is a blown air adjustment unit characterized by this.

[0009] Thus, in the blown air adjustment unit of the present invention, since the buffer member is suspended so as to face the air outlet with a space therebetween, adjustment of the blown air (for example, reduction of the air volume and air speed) can be performed, and direct blowing onto a person directly below the air outlet (or in the vicinity thereof) can be prevented.

[0010] Also, there are a plurality of brackets that are separated from each other. Therefore, compared to conventional products in which the shape of the upper frame portion is fixed and can be attached only to air outlets of specific sizes and shapes, the product of the present invention can be adapted to air outlets of various sizes and shapes. In conventional products, only one pattern of air outlet can be accommodated by one shape of the upper frame portion, but the product of the present invention can accommodate various patterns of air outlets with one shape of bracket (in other words, with the same bracket), and has high versatility. Therefore, also in terms of its production, the number of patterns can be suppressed to be less than before, which is useful in terms of productivity and manufacturing cost. Also, since they are separated from each other, they can be miniaturized and weight-reduced, which facilitates transportation work and the work of attaching them to the air outlet. Also, there is little risk of falling after being attached to an air outlet at a high place provided on the ceiling or the like, and even if it accidentally falls, it is relatively safe. Also, it can be stored in a warehouse or the like with less space.

[0011] Also, since the buffer member is detachable, after attaching the separated lightweight brackets to the air outlet, the buffer member can be separately placed on the placement portion. That is, there is no need to attach the bracket to the air outlet with the buffer member (that is, in a state where the weight is increased), and the unit mounting work is simple. Furthermore, even when replacing the buffer member, only the buffer member can be replaced, and there is no need to remove the entire unit including the bracket, which is simple.

[0012] In this case, in at least a part of the plurality of brackets, a slit is provided in the extending portion, and the buffer member can be inserted into and removed from the placing portion through the slit. Also, in at least a part of the plurality of brackets, a hinge portion enabling rotation of either the placing portion or the extending portion is provided, and the buffer member can be inserted into and removed from the placing portion by rotation of the placing portion or the extending portion via the hinge portion.

[0013] With such a configuration, the insertion and removal of the buffer member onto the placing portion becomes simpler.

[0014] Further, the buffer member can be a filter or a wind shield plate.

[0015] If it is a filter, the air volume and wind speed of the blown air directly below the air outlet can be appropriately reduced. If it is a wind shield plate, it can prevent being blown directly below the air outlet.

[0016] Also, each of the plurality of brackets can be U-shaped in a cross-sectional view, with the mounting portion and the placing portion protruding from the extending portion.

[0017] With such a configuration, it has a relatively simple shape, and manufacturing and transportation are convenient.

[0018] Further, the present invention is a method of mounting a blown air adjustment unit for adjusting the blown air of air-conditioning air from an air outlet disposed on a ceiling, at the air outlet including a blow duct hole provided in the ceiling and an outer frame attached to the ceiling via screws along the outer edge of the blow duct hole, loosening the screws to form a gap between the ceiling and the outer frame, the blown air adjustment unit of the present invention as described above, A method for mounting a blown air adjustment unit is provided, which involves sandwiching the mounting portions of the plurality of brackets in the gap between the formed ceiling and the outer frame, and mounting the buffer member on the placement portion.

[0019] In this way, the blown air adjustment unit can be mounted extremely simply.

Advantages of the Invention

[0020] The blown air adjustment unit of the present invention is applicable not only to the adjustment of the blown air directly below the air outlet, but also to air outlets of various sizes and shapes, and has high versatility. It is also possible to improve the productivity of the blown air adjustment unit (especially with respect to the brackets) and reduce the manufacturing cost. In addition, it can be made smaller and lighter than conventional products, is easy to handle, and has high safety during use. Also, due to the detachable buffer member, it is excellent in terms of ease of replacement. Also, with the mounting method of the blown air adjustment unit of the present invention, it can be mounted extremely simply on the air outlet of the ceiling.

Best Mode for Carrying Out the Invention

[0022] As described above, in the conventional air outlet adjustment unit, there were concerns regarding the low (nonexistent) versatility for air outlets of various sizes and shapes and its weight. Therefore, the inventors of the present invention conducted intensive research on the air outlet adjustment unit. As a result, an air outlet adjustment unit, which includes a plurality of separate brackets (each having an attachment portion attachable to the air outlet, a placement portion on which the bottom surface of the buffer member is placed and supported, and an extension portion connecting these members) that can be attached to the air outlet, and a buffer member. The buffer member is detachably placed on the placement portions of the plurality of brackets attached to the air outlet, and if it is suspended and arranged so as to face the air outlet with a space therebetween, it has high versatility, can correspond to air outlets of various sizes and shapes, and can be made lighter, resulting in excellent workability and safety. Based on these findings, the present invention was completed.

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto. FIG. 1 is a schematic view showing an example of the air outlet adjustment unit of the present invention. Here, the case where the air outlet to be attached is quadrilateral (here, square, but it may also be rectangular) will be described as an example, but the present invention is not limited thereto, and the air outlet adjustment unit of the present invention can also correspond to circular, triangular, or polygonal air outlets with five or more sides.

[0024] The air outlet adjustment unit (hereinafter, also simply referred to as the unit) 1 includes a plurality of brackets 2 (here, 2a to 2d) and a buffer member 3. The brackets 2 can be attached to the air outlet and support the buffer member 3. The buffer member 3 is for adjusting the blown air of the air-conditioning air from the air outlet. FIG. 1 is a perspective view seen from the side of the brackets 2 attached to the air outlet (the side of the attachment portion to be described later), showing a state where the buffer member 3 is placed on the placement portion to be described later and supported by the brackets 2.

[0025] As described above, there are a plurality of brackets 2, which are separated from each other. The number thereof is not limited and can be appropriately determined according to the size and shape of the air outlet as the mounting destination, the weight of the buffer member 3 to be supported, and the like. In the example shown in FIG. 1, the number is four, which is the number for mounting at the four corners of the square air outlet. However, it is not limited to this. For example, it may be a type mounted on the four sides of the square air outlet, or a number corresponding to both the corners and the sides may be prepared.

[0026] For such a plurality of brackets 2 in a separated form, for example, regardless of whether the size of the square air outlet is large or small, they can be mounted on the four corners thereof, which is very useful. Such a mounting correspondence is impossible with conventional products having a fixed size as shown in FIG. 6.

[0027] Similarly, the present invention can also cope with various sizes in air outlets of other shapes. In addition, the inner angles of a polygonal air outlet differ depending on the number of its corners, and therefore the shape suitable for the corner part may also differ. However, if it is a type mounted on the side part without being limited to the corner part, the product of the present invention can be mounted without being limited to the number of corners of the polygon. One type of bracket can be applied to air outlets of various patterns of one shape, making it highly versatile. The number of shape patterns to be manufactured can be reduced, and the manufacturing cost can be reduced. In addition, since the brackets have the same shape, an improvement in productivity can also be expected.

[0028] Furthermore, the bracket 2 is lightened (miniaturized), making it easier to handle, and also facilitating the mounting work, replacement, transportation, etc. to the air outlet. In the case of conventional products, multiple people were required to mount them to the air outlet, but in the case of the bracket 2 of the product of the present invention, it can be mounted by one person. Also, because it is lightweight, it is difficult to fall after mounting, and even if it does fall, it is relatively light and small compared to conventional products, so it is also good in terms of safety.

[0029] The material of the bracket 2 is not particularly limited, but it is preferably a lighter material. For example, if it is aluminum, it is generally lightweight and easy to process. It can be appropriately determined according to costs, the required toughness, the air volume, air velocity, air pressure, etc. of the blown air from the air outlet.

[0030] Next, FIG. 2 is a schematic view (perspective view) showing an example of the bracket 2. Further, FIG. 3 is a cross-sectional view taken along the line A-A' of FIG. 2. For reference of the positional relationship, FIG. 3 also shows the buffer member 3 supported by the bracket 2 and the air outlet provided in the ceiling. That is, the state where the unit 1 is attached to the air outlet is also shown. Note that the air outlet 20 is composed of a blow duct hole 22 provided in the ceiling 21 and an outer frame 24 attached via screws 23 along its outer edge.

[0031] Each bracket 2 has an attachment portion 4, a placement portion 5, and an extension portion 6. The attachment portion 4 is a part attached to the air outlet 20. The placement portion 5 is a part that places and supports the bottom surface of the buffer member 3. The extension portion 6 is a part that is located between the attachment portion 4 and the placement portion 5 and connects them.

[0032] When viewed from the side of the attachment portion 4, the plan view of the bracket 2 is L-shaped. That is, the attachment portion 4 and the placement portion 5 are both L-shaped. This is for attachment to the corner of the square air outlet as described above. The lengths LA and LB of one side of the L-shape (attachment portion 4 and placement portion 5) can be, for example, about 50 mm. The length LC of the extension portion 6 (the distance between the attachment portion 4 and the placement portion 5) can be, for example, about 50 mm. Further, as shown in FIG. 3, in the cross-sectional view taken along the line A-A', it is U-shaped with the attachment portion 4 protruding from one end of the extension portion 6 and the placement portion 5 protruding from the other end. The widths WA and WB of the protruding attachment portion 4 and placement portion 5 can be, for example, about 15 mm. The thickness of each part can be, for example, about 2 mm. Naturally, the overall shape and size of the bracket 2 are not limited to this and can be appropriately determined.

[0033] Here, the four brackets 2 as a whole have the above-described shape, but at least a part of the four brackets can be provided with the following mechanism so that the buffer member 3 can be more easily inserted and removed onto the mounting portion 5.

[0034] The first example is a slit. Fig. 4 shows a bracket having such a slit. A slit 7 is provided in the vicinity of the center of the extension portion 6 parallel to the mounting portion 5. The height width of this slit 7 is at least equal to the thickness of the buffer member 3. This height width can be appropriately determined according to the thickness of the buffer member 3 to be inserted and removed, and can be, for example, about 10 mm. The buffer member 3 can be placed on the mounting portion 5 by passing through this slit 7, or can be carried out from the mounting portion 5 to the outside of the bracket 2.

[0035] The second example is a hinge portion. Fig. 5 shows a bracket having such a hinge portion. The extension portion 6 and the mounting portion 5 are connected via a hinge portion 8, and the mounting portion 5 is rotatable with respect to the extension portion 6 (with the vicinity of the end of the extension portion 6 as the rotation axis). The rotation range of the mounting portion 5 is not particularly limited. For example, in Fig. 5, it can be rotated up and down only above the horizontal plane, and a mechanism can be provided to push up the mounting portion 5 and insert and remove the buffer member 3 through the gap generated thereby (solid arrow [thin]). Or, it can be rotated up and down only below the horizontal plane, and a mechanism can be provided to open the mounting portion 5 to the outside of the bracket 2 to provide a gap for inserting and removing the buffer member 3 (dashed arrow). Or, it may be rotatable up and down across the horizontal plane (solid arrow [thick]). In addition, a mechanism such as a stopper (not shown) can be further provided so that the mounting portion 5 is fixed horizontally so that the buffer member 3 can be firmly supported when placed on the mounting portion 5.

[0036] In addition, in the above, an example in which the mounting portion 5 is configured to be rotatable with respect to the extension portion 6 is given, but it is not limited thereto, and the extension portion 6 may be configured to be rotatable with respect to the mounting portion 5. It may rotate inside the extension portion 6 (the air outlet side), or conversely, it may rotate outside.

[0037] Regarding the rotation of the placement part 5 and the extension part 6 (especially the extension part 6) described above, only a part of them can be configured to be rotatable. In such a case, with the attachment part 4, the extension part 6, and the placement part 5 being partially connected, a part of the placement part 5 or the extension part 6 can be made rotatable.

[0038] Having such a mechanism is preferable because the insertion and removal of the buffer member 3 can be performed more simply. The brackets provided with these slits 7 and hinges 8 can be, for example, two adjacent ones among 2c and 2d, but are not limited to this, and all four can be provided. Also, either only the slits 7 or the hinges 8 can be provided, or both can be provided, and furthermore, another mechanism can be provided.

[0039] Alternatively, even if these mechanisms are not provided, if the buffer member 3 can be bent to some extent, the buffer member 2 can also be inserted and removed through the gap between the brackets 2.

[0040] The buffer member 3 can be suspended and arranged by the above-mentioned bracket 2 so as to face the air outlet 20 with a space therebetween. By this buffer member 3, as shown in FIG. 3, the air volume and air velocity of the blown air can be sufficiently reduced. Therefore, even if there is a person working directly below the air outlet, the blown air can be alleviated to reduce the impact on that person.

[0041] Note that although the blown air also depends on the material of the buffer member 3, a part of it can flow directly downward through the buffer member 3, and the rest can flow horizontally (laterally) along the surface of the buffer member 3 in the space between the air outlet 20 and the buffer member 3, and flow out laterally through the space between the separated brackets 2.

[0042] The buffer member 3 only needs to be able to adjust the blown air and is not particularly limited. For example, it can be a filter. Examples of the filter include saran net (a synthetic fiber made by adding vinyl chloride to polyvinylidene chloride and formed into a net shape) and non-woven fabric. Examples of the material of the non-woven fabric include polypropylene (PP), polyethylene (PE), polyester (PET), PLA (polylactic acid), and the like. With these, by adjusting the mesh density and the like, the blown air can be easily and moderately relaxed as desired.

[0043] In addition, the above filter can be composed only of the filter part made of the above material, but it may also be provided with a holding frame along the outer edge of the filter part. When placed on the placement part 5 of the bracket 2, this holding frame will be placed on the placement part 5. In FIG. 1, an example of the buffer member 3 is the filter 9, the reference numeral 10 is the filter part, and the reference numeral 11 is the holding frame. Also, in the filter part 10, a drug can be impregnated, adhered, or incorporated. For example, an antibacterial agent, an anti-odor agent, a fragrance agent, and the like can be mentioned.

[0044] In addition, it can also be a simple wind shield. It can be made of wood, a metal plate, etc., but considering the weight, it is preferably a plastic such as an acrylic plate, which is relatively lightweight. In the case of this wind shield, it can extremely effectively prevent the blown air from blowing directly below the air outlet.

[0045] Also, the shape of the buffer member 3 is not particularly limited. For example, it can have a shape similar to or the same as the shape of the air outlet 20 (the air outlet duct hole 22). Alternatively, for example, for a circular air outlet 20, it can have a rectangular shape that covers the entire surface. Thus, it may have a shape different from the air outlet 20. According to the desired adjustment degree of the blown air, the arrangement of the air outlet 20, etc., the shape of the buffer member 3 and the shape of the bracket 2 corresponding thereto can be determined.

[0046] Next, an example of the method for attaching the unit 1 of the present invention described above to the air outlet will be described. Here, as an example, a method of attaching to the air outlet 20 arranged on the ceiling 21 as shown in FIG. 3 will be described. As described above, the air outlet 20 is composed of the air outlet duct hole 22 and the outer frame 24 fastened with screws 23. First, loosen the screws 23. Thereby, the outer frame 24 can be lifted from the ceiling 21 to form a gap (for example, about several millimeters). Insert the attachment portion 4 of each bracket 2 into this gap and tighten the screw 23, thereby sandwiching and fixing the attachment portion 4 between the ceiling 21 and the outer frame 24. Then, by using the slit 7 and the hinge portion 8 described above, the buffer member 3 is inserted into the space surrounded by the four brackets 2 and placed and supported on the placement portion 5. By such a procedure, the unit 1 can be easily attached to the air outlet 20.

[0047] In addition, when the air outlet duct protrudes below the ceiling, the unit 1 can be attached by sandwiching the attachment portion 4 of the bracket 2 in the gap between the air outlet duct main body and the outer frame attached to the tip thereof in the same manner as above.

[0048] Also, here, an example of sandwiching and fixing the attachment portion 4 in the gap between the members is given, but it is not limited thereto, and it may be adhesively fixed to the ceiling 21, the outer frame 24, etc., or fixed using screws or the like, and a stronger fixing method can also be adopted. The shape of the attachment portion 4 of the bracket 2 can also be prepared in a more suitable shape according to the fixing method. However, considering the ease of replacement work of the bracket 2, etc., fixing by sandwiching is relatively simple.
