Description

[Technical field]

[0001] The present invention relates to a filter member for a room louver and a room louver provided with the same. [Background technology]

[0002] Conventionally, floor louvers (hereinafter sometimes referred to as "louvers" or "room louvers") have been placed in openings provided in the floor surface to circulate ventilation air and air conditioning air between the space above and below the floor within a building.

[0003] In Patent Document 1, the present applicant has proposed a grille having a molded resin lid that is rectangular in plan view and has multiple openings formed therein, and a molded resin receiving frame that is rectangular in plan view and has openings that penetrate in the vertical direction, and to which the molded resin lid is attached at its upper opening, with a filter positioned within the molded resin receiving frame to prevent the passage of insects and to remove debris.

[0004] In recent years, openable louvers that can open and close the ventilation holes have become popular. For example, Patent Document 2 proposes an openable louver having a structure in which the positions of multiple openings provided in the shutter plate 5 are moved laterally relative to the positions of multiple ventilation holes S in the louver body 3 by the sliding movement of the shutter plate 5 in response to the operation of the shutter operating member 6, thereby opening and closing the louver 1. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 5385621 [Patent Document 2] Utility model registration No. 3198535 Summary of the Invention [Problem to be solved by the invention]

[0006] The louver in Patent Document 2 employs a complex method in which the shutter plate 5 is suspended from three shutter operating members 6, 6, 6 that are supported on the inside of the louver body 3 so that they can slide laterally freely, using screws 7, 7..., and it is also necessary to stretch a separate insect screen 15 below the shutter plate 5, making it impractical.

[0007] An object of the present invention is to provide a filter member for a room louver, which can adjust the dust prevention and ventilation opening area simply by placing it within a receiving frame, and a room louver equipped with the same. [Means for solving the problem]

[0008] The filter member of the present invention has a lid having a plurality of openings and a receiving frame having an opening penetrating in the vertical direction and the lid is attached to an upper opening, and is used by being placed in the receiving frame of a room louver that is installed in an air vent provided on a floor surface, and the filter member includes a frame portion having a plurality of openings and the The frame portion The camera includes a filter frame having a filter stretched across an opening, a shutter in which a plurality of openings are formed, and a shutter cover which has a plurality of openings formed therein and slidably houses the shutter between the filter frame and the shutter cover. The filter member of the present invention has a lid having a plurality of openings and a receiving frame having an opening penetrating in the vertical direction and the lid is attached to an upper opening, and is used by being placed in a receiving frame of a room louver that is installed in an air vent provided on a floor surface, and the filter member is used by being placed in the receiving frame of a room louver that is installed in an air vent provided on a floor surface, The frame portion A filter frame having a filter stretched across an opening, a plurality of openings formed therein, stacked and relatively slidable. Open with The camera includes a pair of shutters whose aperture area is adjustable, and a shutter cover that has a plurality of openings and slidably houses the pair of shutters between the filter frame and the shutter cover.

[0009] According to the above configuration, the filter member comprises a filter frame having a filter capable of keeping out dust and insects, and a shutter with an adjustable opening area. Simply by arranging this filter member in the receiving frame of the room louver, dust and insects can be kept out and the ventilation opening area of ​​the room louver can be adjusted (air volume adjustment). In the present invention, the shutter may be one piece or two or more pieces. When one piece is used, the air volume can be adjusted in relation to the opening position of the room louver lid and / or the shutter lid. When two or more pieces are used, more fine adjustment of the air volume can be performed.

[0010] In the above configuration, the filter frame has a periphery that is rectangular in plan view by a pair of vertical bars and a pair of horizontal bars, Filter frame The pair of vertical bars is connected by a plurality of inner horizontal bars. The frame portion A plurality of openings are formed, and the shutter has a rectangular periphery in a plan view formed by a pair of vertical bars and a pair of horizontal bars. Shutter The pair of vertical bars is connected by a plurality of inner horizontal bars. Shutter A plurality of openings are formed, Shutter An inner vertical bar is formed inside the opening, and the shutter cover has a rectangular periphery in a plan view formed by a pair of vertical bars and a pair of horizontal bars. Shutter cover The pair of vertical bars is connected by a plurality of inner horizontal bars. Shutter cover A plurality of openings are formed, Shutter cover It is preferable that locking pieces are formed so as to protrude from the pair of vertical bars and be capable of being locked to the vertical bars of the filter frame.

[0011] According to the above configuration, since the inner vertical bars are formed in the opening of the shutter or pair of shutters, even if the ventilation opening area is changed by sliding the shutter or pair of shutters, the horizontal bars and / or inner vertical bars of the shutter or pair of shutters overlap with the inner horizontal bars of the shutter cover below. As a result, the horizontal bars and / or inner vertical bars of the shutter are always supported by the inner horizontal bars of the shutter cover. Therefore, downward bending of the shutter or pair of shutters can be restricted. In addition, even if the shutter is a thin sheet, the change over time in the ventilation opening area due to downward bending of the shutter can be restricted. As a result, the filter member can be made thinner and lighter.

[0012] It is also possible to provide a filter member having a simple configuration in which a shutter or a pair of shutters is slidably disposed between the filter frame and the shutter lid, and the locking piece of the shutter lid is locked to the filter frame.

[0013] The room louver of the present invention is a room louver that is installed in a ventilation opening provided in a floor surface, and includes a lid having a plurality of openings formed therein, a receiving frame having an opening penetrating in the vertical direction and in which the lid is attached to an upper opening, and a filter member that is installed within the receiving frame, and the filter member is a frame portion having a plurality of openings formed therein and the The frame portion The camera includes a filter frame having a filter stretched across an opening, a shutter in which a plurality of openings are formed, and a shutter cover which has a plurality of openings formed therein and slidably houses the shutter between the filter frame and the shutter cover. The present invention also provides a room louver that is installed in a ventilation opening provided in a floor surface, and includes a lid having a plurality of openings formed therein, a receiving frame having an opening penetrating therethrough in the vertical direction and in which the lid is attached to an upper opening, and a filter member that is installed within the receiving frame, and the filter member is a frame having a plurality of openings formed therein and a receiving frame having an opening penetrating therethrough in the vertical direction. The frame portion A filter frame having a filter stretched across an opening, a plurality of openings formed therein, stacked and relatively slidable. Open withThe camera includes a pair of shutters whose aperture area is adjustable, and a shutter cover in which a plurality of openings are formed and which slidably houses the pair of shutters between the filter frame and the shutter cover.

[0014] According to the above configuration, the filter member comprises a filter frame having a filter capable of keeping out dust and insects, and a shutter with an adjustable opening area. Simply by arranging this filter member inside the receiving frame of the room louver, dust and insects can be kept out and the ventilation opening area of ​​the room louver can be adjusted. In the present invention, the shutter may be one piece or two or more pieces. When one piece is used, the air volume can be adjusted in relation to the opening position of the room louver lid and / or the shutter lid. When two or more pieces are used, more fine adjustment of the air volume can be performed. Furthermore, in the present invention, the shutter and shutter cover are preferably in the form of a thin plate or sheet. For example, the thickness is preferably 1.0 to 0.1 mm, more preferably 0.6 to 0.2 mm. By forming the shutter and / or shutter cover from a thin resin sheet, the shutter and / or shutter cover is lifted by the airflow when the wind blows out from under the floor into the room, and the air volume can be adjusted by increasing the adhesion between the shutters and / or shutter covers (sheets). In other words, by utilizing the lifting of the sheet due to the airflow when the wind blows out, the area can be narrowed by sliding in two dimensions, and the lifting can increase the adhesion between the sheets in three dimensions, thereby improving the effect of adjusting the air volume.

Fig. 1(a) shows a partial plan view of the room louver 1, Fig. 1(b) shows a front view of the room louver 1, Fig. 1(c) shows a bottom view of the room louver 1, Fig. 1(d) shows a cross-sectional view of the room louver 1 (a view taken along line Id-Id in Fig. 1), and Fig. 1(e) shows a side view of the room louver 1 (a view seen from the Ie direction in Fig. 1). Figs. 1(b) and 1(d) show the room louver 1 installed in a ventilation opening 10A provided in a floor surface 10.

[0019] As shown in Fig. 1(a) and Fig. 1(b), the room louver 1 has a lid 2, a receiving frame 3, and a filter member 4 installed in the receiving frame 3. At X on the left side of Fig. 1(a), the lid 2 is shown without in order to show the configuration inside the receiving frame 3. The filter member 4 is visible at X. The dimensions of the room louver 1 are not particularly limited. For example, the longitudinal length of the room louver 1 is 25 to 180 cm, the width is 5 to 20 cm, and the height is 2 to 5 cm.

[0020] As shown in FIG. 1(a), the lid 2 has a plurality of vertical bars 2a and a plurality of horizontal bars 2b. The multiple vertical bars 2a are arranged along the longitudinal direction of the room louver 1. The multiple vertical bars 2a are lined up at approximately equal intervals in a direction perpendicular to the longitudinal direction. The multiple horizontal bars 2b are arranged along a direction perpendicular to the longitudinal direction of the room louver 1. The multiple horizontal bars 2b are lined up at approximately equal intervals in the longitudinal direction of the room louver 1. A plurality of openings 2A are formed in the lid 2 by the multiple vertical bars 2a and the multiple horizontal bars 2b. The lid 2 is attached to an upper opening 3a (see FIG. 1(b)) of the receiving frame 3.

[0021] As shown in Fig. 1(b) to Fig. 1(e), the receiving frame 3 is a rectangular, bottomed, square cylinder in plan view. As shown in Fig. 1(c), a plurality of bottom openings 3b are formed in the bottom 3U of the receiving frame 3. As shown in Fig. 1(b) and Fig. 1(c), the receiving frame 3 is formed with an opening 3A that penetrates the upper opening 3a and the bottom opening 3b. The receiving frame 3 may be a cylinder without the bottom 3U.

[0022] 1(d), the frame 3 is fixed to a floor 12 by nails 13 or the like. In order to increase the strength of the frame 3, a metal member such as a steel plate may be attached to the frame 3.

[0023] The lid 2 and the receiving frame 3 are made of resin, such as polypropylene, polyethylene, and polystyrene.

[0024] 1(b) and 1(d), a filter member 4 is disposed within the receiving frame 3. The filter member 4 is disposed below the lid 2 at a position slightly spaced therefrom.

[0025] 2 to 5 show the filter member 4.

[0026] 2, the filter member 4 has a filter frame 20, a pair of shutters 30, and a shutter lid 40. The pair of shutters 30 has two shutters, a first shutter 31 and a second shutter 32. The pair of shutters 30 and the shutter lid 40 are slightly shorter than the filter frame 20 in the longitudinal direction.

[0027] 3A, the filter frame 20 has a frame portion 21 and a filter 22, such as a mesh filter. The frame portion 21 has a pair of vertical bars 23, a pair of horizontal bars 24, and a plurality of inner horizontal bars 25.

[0028] The pair of vertical bars 23 has two vertical bars 123 and two vertical bars 223 arranged along the longitudinal direction of the filter frame 20. The pair of horizontal bars 24 has two horizontal bars 124 and two horizontal bars 224 arranged along a direction perpendicular to the longitudinal direction of the filter frame 20. The pair of vertical bars 23 and the pair of horizontal bars 24 give the periphery of the filter frame 20 a rectangular shape in plan view.

[0029] The multiple inner horizontal bars 25 are arranged between a pair of horizontal bars 24 (between horizontal bar 124 and horizontal bar 224) along a direction perpendicular to the longitudinal direction. The multiple inner horizontal bars 25 are arranged at approximately equal intervals in the longitudinal direction of the filter frame 20. The multiple inner horizontal bars 25 connect a pair of vertical bars 23 (vertical bar 123 and vertical bar 223), thereby forming multiple openings 20a (six openings 20a in this embodiment) in the filter frame 20. A filter 22 is stretched over each opening 20a.

[0030] FIG. 3B shows the filter frame 20 shown in FIG. 3A viewed from the opposite direction.

[0031] 3B, four small grooves 123t are formed in the vertical beam 123 and are recessed inward. The four small grooves 123t are spaced apart in the longitudinal direction of the filter frame 20. Near the center of the vertical beam 123, an elongated groove 123S is formed that is recessed inward.

[0032] Further, a handle portion 123P that protrudes upward in the drawing is formed near the center of the vertical bar 123. The entire filter member 4 including the filter frame 20 can be lifted by grasping the handle portion 123P. When removing the filter member 4 from the receiving frame 3 shown in FIG. 1(b) etc., the filter member 4 can be easily removed by using the handle portion 123P.

[0033] 3A, four small grooves 223t recessed inward are also formed in the vertical beam 223. The four small grooves 223t are spaced apart in the longitudinal direction of the filter frame 20. Near the center of the vertical beam 223, an elongated groove 223S recessed inward is formed. In this embodiment, no handle portion is formed on the vertical crosspiece 223, but the vertical crosspiece 223 may have a handle portion formed thereon.

[0034] The frame portion 21 of the filter frame 20 is made of resin. The resin is not particularly limited, and examples thereof include polypropylene, polyethylene, and polystyrene.

[0035] Next, a pair of shutters 30 (first shutter 31 and second shutter 32) shown in Fig. 2 will be described. In this embodiment, since the first shutter 31 and the second shutter 32 have the same configuration, the following describes the second shutter 32 and omits a description of the first shutter 31.

[0036] As shown in FIG. 4, the second shutter 32 has a pair of vertical bars 33, a pair of horizontal bars 34, an inner horizontal bar 35, and an inner vertical bar 36.

[0037] The pair of vertical bars 33 has two vertical bars 133 and two vertical bars 233 arranged along the longitudinal direction of the second shutter 32. The pair of horizontal bars 34 has two horizontal bars 134 and two horizontal bars 234 arranged along a direction perpendicular to the longitudinal direction of the second shutter 32. The pair of vertical bars 33 and the pair of horizontal bars 34 give the periphery of the first shutter 31 a rectangular shape in plan view.

[0038] The multiple inner horizontal bars 35 are arranged between a pair of horizontal bars 34 (between the horizontal bar 134 and the horizontal bar 234) along a direction perpendicular to the longitudinal direction. The multiple inner horizontal bars 35 are arranged at approximately equal intervals in the longitudinal direction of the second shutter 32. The multiple inner horizontal bars 35 connect a pair of vertical bars 33 (the vertical bar 133 and the vertical bar 233), thereby forming multiple openings 30a (four openings 30a in this embodiment) in the second shutter 32.

[0039] An opening 30a of the second shutter 32 is slightly smaller than the opening 20a of the filter frame 20 shown in Figure 3A. An inner horizontal rail 35 of the second shutter 32 is wider than the inner horizontal rail 25 of the filter frame 20 shown in Figure 3A.

[0040] Two inner vertical bars 36 are formed in each opening 30a. The two inner vertical bars 36 are arranged along the longitudinal direction of the second shutter 32. The two inner vertical bars 36 are spaced apart in a direction perpendicular to the longitudinal direction of the first shutter 31. The two inner vertical bars 36 divide the opening 30a into three sections.

[0041] Vertical beam 133 has an outwardly convex protrusion 133S formed slightly toward one end near the center in the longitudinal direction. Vertical beam 233 also has an outwardly convex protrusion 233S formed slightly toward one end near the center in the longitudinal direction.

[0042] A handle portion 134Q that protrudes downward in the figure is formed on the horizontal beam 134. The handle portion 134Q is formed, for example, by bending a portion that extends in the planar direction of the horizontal beam 134. The first shutter 31 can be slid by gripping the handle portion 134Q.

[0043] As shown in Fig. 2, the first shutter 31 and the second shutter 32 are arranged so that their handles 134Q are located on opposite sides in the longitudinal direction. In Fig. 2, the handle 134Q of the first shutter 31 is located on the right side in the figure, and the handle 134Q of the second shutter 32 is located on the left side in the figure.

[0044] Next, the shutter cover 40 shown in FIG. 2 will be described.

[0045] As shown in FIG. 5, the shutter cover 40 has a pair of vertical bars 43, a pair of horizontal bars 44, an inner horizontal bar 45, and an inner vertical bar 46.

[0046] The pair of vertical bars 43 has two vertical bars 143 and two vertical bars 243 arranged along the longitudinal direction of the shutter cover 40. The pair of horizontal bars 44 has two horizontal bars 144 and two horizontal bars 244 arranged along a direction perpendicular to the longitudinal direction of the shutter cover 40. The pair of vertical bars 43 and the pair of horizontal bars 44 give the shutter cover 40 a rectangular periphery in a plan view.

[0047] The multiple inner horizontal bars 45 are arranged between a pair of horizontal bars 44 (between the horizontal bar 144 and the horizontal bar 244) along a direction perpendicular to the longitudinal direction. The multiple inner horizontal bars 45 connect the pair of vertical bars 43 to form multiple openings 40a (four openings 40a in this embodiment) in the shutter lid 40.

[0048] The opening 40a of the shutter cover 40 is approximately the same size as the opening 30a of the second shutter 32 shown in Fig. 4. The inner horizontal rail 45 of the shutter cover 40 has approximately the same width as the inner horizontal rail 35 of the second shutter 32. The opening 40a of the shutter cover 40 is slightly smaller than the opening 20a of the filter frame 20 shown in Figure 3A. The inner horizontal rail 45 of the shutter cover 40 is wider than the inner horizontal rail 25 of the filter frame 20 shown in Figure 3A.

[0049] Two inner vertical bars 46 are formed in each opening 40a. The two inner vertical bars 46 are arranged along the longitudinal direction of the shutter cover 40. The two inner vertical bars 46 are spaced apart in a direction perpendicular to the longitudinal direction of the shutter cover 40.

[0050] The vertical bar 143 has four locking pieces 143t formed thereon that protrude upward in the drawing. The four locking pieces 143t are spaced apart in the longitudinal direction of the shutter cover 40. The vertical bar 243 has four locking pieces 243t formed thereon that protrude upward in the drawing. The four locking pieces 243t are spaced apart in the longitudinal direction of the shutter cover 40. The locking pieces 143t are formed, for example, by bending a portion of the vertical bar 143 that protrudes in the surface direction. The locking pieces 243t are formed, for example, by bending a portion of the vertical bar 243 that protrudes in the surface direction.

[0051] The pair of shutters 30 and the shutter lid 40 shown in Fig. 2 are made of resin. The resin is not particularly limited, and examples thereof include polypropylene, polyethylene, and polystyrene. The pair of shutters 30 and the shutter lid 40 are formed, for example, by using a sheet-like or plate-like member that has been punched. The thickness of the shutter 30 and the shutter lid 40 is preferably 1.0 to 0.1 mm, and more preferably a thin sheet-like member having a thickness of 0.6 to 0.2 mm.

[0052] Next, an example of a method for assembling the filter member 4 will be described.

[0053] The pair of shutters 30 (first shutter 31 and second shutter 32) shown in FIG. 2 are overlapped, and the handle portion 134Q of the first shutter 31 and the handle portion 134Q of the second shutter 32 are folded as shown in FIG.

[0054] Next, the pair of overlapping shutters 30 are placed on the filter frame 20. At this time, the protrusion 233S of the first shutter 31 and the protrusion 133S of the second shutter 32 are positioned in the long groove 123S (see FIG. 3B) of the filter frame 20. In addition, the protrusion 133S of the first shutter 31 and the protrusion 233S of the second shutter 32 shown in FIG. 2 are positioned in the long groove 223S of the filter frame 20.

[0055] Next, the shutter lid 40 is placed on the pair of shutters 30. Then, the four locking pieces 143t of the shutter lid 40 are fitted into the four small grooves 123t (see FIG. 3B) of the filter frame 20, respectively. Also, the four locking pieces 243t of the shutter lid 40 shown in FIG. 2 are fitted into the four small grooves 223t of the filter frame 20, respectively. This causes the shutter lid 40 to be locked to the filter frame 20.

[0056] Next, an example in which the opening area of ​​the pair of shutters 30 is changed by sliding the pair of shutters 30 will be described with reference to Figs. 6 to 8. In Figs. 6 to 8, the mesh filter 22 is omitted so that the opening of the pair of shutters 30 can be easily seen. Also, the first shutter 31 and the second shutter 32 are each given a different color. Also, the shutter cover 40 is hatched.

[0057] 6 shows the state where the opening 30a of the first shutter 31, the opening 30a of the second shutter 32, and the opening 40a of the shutter cover 40 overlap in the vertical direction in the figure. The opening 30a of the first shutter 31, the opening 30a of the second shutter 32, and the opening 40a of the shutter cover 40 are fully open (fully open state). At this time, the opening area of ​​the pair of shutters 30 is the largest. When the filter member 4 is placed in the receiving frame 3 of the room louver 1 shown in FIG. 1(b) in the state shown in FIG. 6, the amount of ventilation of the room louver 1 is large.

[0058] 7 shows a state in which the opening 30a of the first shutter 31, the opening 30a of the second shutter 32, and the opening 40a of the shutter cover 40 are almost closed (almost completely closed state). At this time, the opening area of ​​the pair of shutters 30 is the smallest. Since the filter member 4 is in the state shown in FIG. 7, when it is placed in the receiving frame 3 of the room louver 1 shown in FIG. 1(b), the amount of ventilation of the room louver 1 is small.

[0059] Fig. 8 shows the opening 30a of the first shutter 31, the opening 30a of the second shutter 32, and the opening 40a of the shutter lid 40 in a slightly open state. The opening 30a of the first shutter 31, the opening 30a of the second shutter 32, and the opening 40a of the shutter lid 40 are neither in the fully open state shown in Fig. 6 nor in the almost fully closed state shown in Fig. 7. The opening area of ​​the pair of shutters 30 shown in Fig. 8 is smaller than the opening area in the state shown in Fig. 6, and is larger than the opening area in the state shown in Fig. 7.

[0060] The state in which the opening 30a of the first shutter 31, the opening 30a of the second shutter 32, and the opening 40a of the shutter lid 40 are neither fully open nor nearly fully closed is not limited to the state shown in FIG.

[0061] According to the filter member 4 and the room louver 1 according to the above-described embodiment, the following effects can be obtained.

[0062] Conventional room louvers have a complex structure in which a shutter operating member is provided on the lid or the like and a shutter is suspended from the shutter operating member. However, in this embodiment, as shown in Fig. 2, the filter member 4 includes a filter frame 20 and a pair of shutters 30. The filter frame 20 has a filter 22 that can keep out dust and insects. As shown in Figs. 6 to 8, the pair of shutters 30 can adjust the opening area by sliding. The room louver 1 having the filter member 4 is assembled, for example, by the following method. As shown in FIG. 1(d), the frame 3 of the room louver 1 is fixed to a floor 12 by nails 13 or the like. The filter member 4 is placed inside the frame 3. Thereafter, the lid 2 is attached to the frame 3. In this way, simply by arranging the filter member 4 inside the receiving frame 3 of the room louver 1 shown in the figure, it is possible to keep out dust and insects, and also to adjust the ventilation opening area of ​​the room louver 1.

[0063] In addition, in conventional configurations, the shutter with an adjustable opening area was often arranged so as to be in contact with the underside of the room louver lid. In this case, when the room louver lid is deflected by the load of a person or the like, the shutter in contact with the underside of the lid may also deflect. If the shutter deflects, it becomes difficult to slide the shutter. In order to prevent the shutter from deflecting, it is necessary to make the shutter thicker or to use a material with high strength. However, this causes problems such as an increase in the thickness and weight of the shutter.

[0064] According to this embodiment, a pair of shutters 30 whose opening area is adjustable are stored in the filter member 4. As shown in FIG. 1(b) and FIG. 1(d), the filter member 4 is often placed in a position slightly away from the cover 2 in the receiving frame 3 of the room louver 1. In this case, the pair of shutters 30 of the filter member 4 are also placed in a position slightly away from the cover 2 of the room louver 1. Even if the cover 2 of the room louver 1 is bent due to a load of a person or the like, the pair of shutters 30 stored in the filter member 4 are not likely to bend because they are away from the cover 2. In addition, there is no risk of the pair of shutters 30 being deformed. Therefore, it is not necessary to thicken the pair of shutters 30 or to use a material with high strength for the shutters 30. The shutters 30 can be made thinner and lighter.

[0065] As shown in FIG. 4, the second shutter 32 has an inner vertical bar 36 formed in the opening 30a. The first shutter 31 shown in FIG. 2 has the same structure. Therefore, even when the pair of shutters 30 are slid, the inner horizontal bar 35 and / or the inner vertical bar 36 of the first shutter 31 overlap with the inner horizontal bar 45 of the shutter cover 40 located below (see FIGS. 6 to 8, etc.). Also, the inner horizontal bar 35 and / or the inner vertical bar 36 of the second shutter 32 overlap with the inner horizontal bar 45 of the shutter cover 40 located below. In the overlapping portion, the first shutter 31 and / or the second shutter 32 are supported by the shutter cover 40. Therefore, downward bending of the first shutter 31 and the second shutter 32 can be restricted. Also, even if the first shutter 31 and the second shutter 32 are thin sheet-like, the change over time in the ventilation opening area due to downward bending can be restricted. As a result, the filter member 4 can be made thinner and lighter.

[0066] Furthermore, as shown in FIG. 2, a filter member 4 having a simple configuration can be provided in which a pair of shutters 30 are slidably arranged between the filter frame 20 and the shutter lid 40, and the locking piece 143t of the shutter lid 40 is locked to the filter frame 20.

[0067] Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration should not be considered to be limited to these embodiments. The scope of the present invention is indicated by the claims rather than the above description, and includes all modifications within the meaning and scope of the claims.

[0068] For example, in the above-described embodiment, as shown in FIG. 4, two inner vertical bars 36 are formed in the opening 30a of the second shutter 32. Similarly, two inner vertical bars (36) are formed in the opening (30a) of the first shutter 31 shown in FIG. 2. However, when inner vertical bars are formed in the opening of a shutter constituting a pair of shutters (30), the number, position, width, shape, and the like of the inner vertical bars can be changed. In addition, inner vertical bars do not have to be formed in the opening of a shutter constituting a pair of shutters (30). In addition, the handle portion 134Q of the first shutter 31 and / or the second shutter 32 does not have to be provided.

[0069] In the above-described embodiment, as shown in Fig. 4, a plurality of inner horizontal bars 35 are formed within the opening 30a of the second shutter 32. Similarly, a plurality of inner horizontal bars 35 are formed within the opening 30a of the first shutter 31 shown in Fig. 2. However, when inner horizontal bars are formed within the opening of a shutter constituting a pair of shutters (30), the number, position, width, shape, etc. of the inner horizontal bars can be changed. Also, inner horizontal bars do not have to be formed on a shutter constituting a pair of shutters (30).

[0070] In the above-described embodiment, as shown in Fig. 2, a plurality of locking pieces 143t are formed on the shutter lid 40. The locking pieces 143t are locked to the filter frame 20. However, the number, position, size, shape, etc. of the locking pieces formed on the shutter lid can be changed. Also, the locking pieces do not have to be formed on the shutter lid.

[0071] In the above-described embodiment, as shown in Fig. 5, the shutter cover 40 is formed with a plurality of inner horizontal bars 45. However, when the shutter cover has inner horizontal bars formed thereon, the number, position, width, shape, etc. of the inner horizontal bars can be changed. Also, the shutter cover does not necessarily have to have inner horizontal bars formed thereon.

[0072] In the above-described embodiment, as shown in Fig. 5, a plurality of inner vertical bars 46 are formed within the opening 40a of the shutter lid 40. However, when the shutter lid has inner vertical bars formed therein, the number, position, width, shape, etc. of the inner vertical bars can be changed. Also, the shutter lid does not necessarily have to have inner vertical bars formed therein.

[0073] In addition, the number, positions, sizes, shapes, etc. of the openings 20a in the filter frame 20, the openings 30a in the first shutter 31, the openings 30a in the second shutter 32, and the openings 40a in the shutter lid 40 can be changed. In addition, the openings 30a in the first shutter 31, the openings 30a in the second shutter 32, and the openings 40a in the shutter lid 40 do not have to be the same size.

[0074] In the above embodiment, as shown in FIG. 2, the pair of shutters 30 is composed of two shutters, the first shutter 31 and the second shutter 32. However, the number of shutters constituting the pair of shutters may be one or three or more. When there is one shutter, the air volume can be adjusted by the opening position of the room louver cover 2 and / or the shutter cover 40, that is, the relationship with the vertical bars 2a and horizontal bars 2b of the cover 2 and / or the inner vertical bars 46 and horizontal bars 44, 45 of the shutter cover 40. When there are two or more shutters, more detailed air volume adjustment can be performed. In addition, when there are two or more shutters in the present invention, the shutter cover 40 may be omitted. In other words, the shutter cover 40 only needs to have a role of supporting the shutter and also needs to support the filter frame 20 above it. For example, when two shutters, the first shutter 31 and the second shutter 32, are used, the second shutter 32 can be substituted for the shutter cover 40.

[0075] In the above embodiment, the two shutters (first shutter 31, second shutter 32) constituting the pair of shutters 30 shown in Fig. 2 have the same configuration. However, all of the shutters constituting the pair of shutters may have different configurations, or at least one shutter may have a different configuration from the other shutters.

[0076] In the above embodiment, the two shutters (first shutter 31, second shutter 230) constituting the pair of shutters 30 shown in Fig. 2 have substantially the same configuration as the shutter cover 40. However, the shutters and the shutter cover constituting the pair of shutters may have different configurations.

[0077] In the above-described embodiment, as shown in Fig. 2, long grooves 123S and 223S are formed in filter frame 20. Protrusions 133S and 233S of a pair of shutters 30 are arranged in long grooves 123S and 223S. The number, positions, shapes, etc. of the long grooves in which the protrusions of the pair of shutters are arranged can be changed. The number, positions, shapes, etc. of the protrusions arranged in the long grooves of the filter frame can be changed.

[0078] In the above embodiment, the room louver 1 shown in Fig. 1(a) has two receiving frames 3 which are connected to each other. However, the number of receiving frames of the room louver of the present invention may be one, or three or more.

[0079] Furthermore, the shapes of the cover and the receiving frame of the room louver of the present invention can be changed. [Explanation of symbols]
