[0026] Hereinafter, embodiments will be described with reference to the drawings. Features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. Because the drawings are provided for illustrative purposes only, the scope of the present invention is not limited to the examples in the drawings.

[0027] <1. Room> FIG. 1 shows a living room in a house. This room is a living room, dining room, and kitchen area surrounded by a first wall 11, a second wall 12, a third wall 13, and a fourth wall. The first wall 11 faces the second wall 12, and the third wall 13 faces the fourth wall. A system kitchen counter 15 is installed away from the walls 11 and 12 and adjacent to the third wall 13. A cupboard 16 with a top is installed on the first wall 11 and the floor, close to the first wall 11, and a hanging shelf 18 is installed on the first wall 11 above and spaced apart from the cupboard 16. An indoor unit 19 and a screen 30 for an air conditioner are installed on the first wall 11 next to the hanging shelf 18. The hanging shelf 18 and the screen 30 are side-by-side at the same height, and the indoor unit 19 is hidden behind the screen 30. Instead of the indoor unit 19, a circulator, an electric fan, an air purifier, a humidifier, or a dehumidifier may be installed on the first wall 11. The indoor unit 19, the circulator, the electric fan, the air purifier, the humidifier, and the dehumidifier are all types of air conditioning equipment. The object that is concealed by the concealing body 30 may be something other than an air conditioning equipment, as long as it is attached to a wall.

[0028] <2. Blindfolded Body> Figure 2 is a perspective view of the cover body 30, Figure 3 is an exploded perspective view of the cover body 30, Figure 4 is a left side view of the cover body 30, Figure 5 is a right side view of the cover body 30, Figure 6 is a top view of the cover body 30, Figure 7 is a back view of the cover body 30, and Figure 8 is a perspective view of the main frame 40 of the cover body 30.

[0029] The privacy screen 30 comprises a main frame 40, side louvers 50, a front louver 60 and a plurality of hooks 70.

[0030] The main body frame 40 is fixed to the first wall 11 on the left and right sides of the indoor unit 19. The front louvers 60 are attached to the front of the main body frame 40 and conceal the front of the indoor unit 19. The front louvers 60 are detachable from the main body frame 40. The side louvers 50 are attached to the left side of the main body frame 40 and conceal the left side of the indoor unit 19.

[0031] The main body frame 40 has a pair of side frames 41 and a front beam 48 .

[0032] A pair of side frames 41 are fixed to the first wall 11, side by side with a gap between them. The side frames 41 are shaped like a square or rectangular frame, and have a rectangular or square opening in the center. The side frames 41 are made of metal such as stainless steel or aluminum alloy. The side frames 41 may be magnetic, particularly paramagnetic.

[0033] The side frame 41 has a base member 42, upper arms 43, lower arms 44, and vertical members 45. The base member 42, upper arms 43, lower arms 44, and vertical members 45 are made of square bars, more specifically, hollow square pipes. The base member 42 extends vertically in the up-down direction on the side of the indoor unit 19 and is fixed to the first wall 11 with screws or the like. The upper end of the base member 42 is joined to the rear end of the upper arms 43, and the upper arms 43 extend from the upper end of the base member 42 in a direction perpendicular to the first wall 11. The lower end of the base member 42 is joined to the rear end of the lower arms 44, and extends from the lower ends of the lower arms 44 perpendicular to the first wall 11. The upper end of the vertical members 45 is joined to the front ends of the upper arms 43, and the lower end of the vertical members 45 is joined to the front ends of the lower arms 44, and the vertical members 45 extend vertically in the up-down direction. The base material 42 and the vertical member 45 are parallel to each other, and the upper arm 43 and the lower arm 44 are parallel to each other.

[0034] The front crosspiece 48 is made of a square bar, more specifically, a hollow square pipe. The front crosspiece 48 spans between the front and upper ends of the two side frames 41. Both ends of the front crosspiece 48 are connected to the two side frames 41, respectively. Specifically, as shown in FIG. 9 , an L-shaped joint 46 protrudes from the upper front corner of the left side of the right side frame 41 toward the opposite side frame 41, and the joint 46 is fitted into an opening at the right end of the front crosspiece 48. The joint 46 may be fastened to the front crosspiece 48 with a screw or a nail. Similarly, the joint of the left side frame 41 is fitted into an opening at the left end of the front crosspiece 48.

[0035] As shown in Figures 2 to 7, the side louver 50 is attached to the left side surface of the main body frame 40, i.e., the left side surface of the left side frame 41. The side louver 50 is a horizontal louver. The side louver 50 has two vertical bars 51 and a plurality of blades 52.

[0036] The vertical bars 51 are made of square bars, more specifically hollow square pipes. The vertical bars 51 are made of metal such as stainless steel or aluminum alloy. The vertical bars 51 may be magnetic, particularly paramagnetic. The vertical bars 51 are arranged parallel to one another with gaps between them. The vertical length of the vertical bars 51 is set to match the vertical size of the hanging shelf 18. In other words, the larger the vertical size of the hanging shelf 18, the longer the vertical length of the vertical bars 51.

[0037] The slats 52 are made of wooden strips such as solid wood, plywood, laminated wood, or particle board. A decorative sheet may be attached to the surface of the slats 52, or the slats 52 may be painted. If the slats 52 are made of solid wood, the wood grain of the solid wood may be visible on the surface of the slats 52, or the slats 52 may be painted so that the wood grain remains. The slats 52 may also be molded resin products with a wood grain pattern. The number of slats 52 is set according to the vertical size of the hanging shelf 18. In other words, the larger the vertical size of the hanging shelf 18, the more slats 52 are required.

[0038] Because the side louvers 50 are horizontal louvers, the multiple blades 52 extend horizontally parallel to one another and are aligned vertically at equal intervals along the vertical bars 51. The blades 52 are fixed to the vertical bars 51 with screws in a horizontally facing position. The blades 52 have a thickness in the direction in which the vertical bars 51 extend. The screws are fastened to the blades 52 from the side of the vertical bars 51. The heads of the screws may fit inside the vertical bars 51. The blades 52 may also be fixed to the vertical bars 51 with fasteners other than screws.

[0039] At the intersection of the vane 52 and the vertical crosspiece 51, a notch may be formed in both the vane 52 and the vertical crosspiece 51, and the notch in the vane 52 and the notch in the vertical crosspiece 51 may fit into the notch in the other vane 52 like a half-notch joint. At the intersection of the vane 52 and the vertical crosspiece 51, a notch may be formed in either the vane 52 or the vertical crosspiece 51, and the other may fit into the notch like a half-notch joint.

[0040] The position of the upper end of the vertical crosspiece 51 is aligned with or lower than the position of the upper surface of the uppermost blade 52. Therefore, the vertical crosspiece 51 does not protrude above the upper surface of the blade 52. The position of the lower end of the vertical crosspiece 51 is aligned with or higher than the position of the lower surface of the lowermost blade 52.

[0041] The side louver 50 is attached to the left side surface of the main body frame 40 as follows. One of the vertical beams 51 is placed against the left side surface of the base material 42 of the left side frame 41, and the vertical beam 51 is fixed to the base material 42 with a screw. The screw is fastened into the vertical beam 51 from the side of the base material 42. The head of the screw may fit inside the vertical beam 51. The other vertical beam 51 is placed against the left side surface of the vertical member 45 of the left side frame 41, and the vertical beam 51 is fixed to the vertical member 45 with a screw. The screw is fastened into the vertical beam 51 from the side of the vertical member 45. The head of the screw may fit inside the vertical beam 51.

[0042] When viewed from the left of the privacy screen 30, the vertical bars 51 are disposed behind the slats 52. Therefore, the vertical bars 51 are not noticeable when viewed from the left of the privacy screen 30. If the vertical bars 51 are a dark color, particularly black, the vertical bars 51 are even less noticeable.

[0043] In addition, a second side louver provided in the same manner as the side louver 50 may be attached to the right side surface of the main body frame 40. If the second side louver is attached to the right side surface of the main body frame 40, the privacy screen 30 will be symmetrical.

[0044] The front louvers 60 are attached to the front of the main frame 40, i.e., in front of the side frames 41 and front crosspieces 48. The front louvers 60 are arranged so that they can be raised from a state in which they are swung down along the front of the main frame 40 to a state in which they are swung up from the front of the main frame 40, and vice versa. The front louvers 60 are arranged so that they can be detached from the main frame 40. To prevent the front louvers 60 from falling even if they are accidentally detached from the main frame 40, a flexible wire 90 such as a string, webbing, rope, wire, or tape connects the main frame 40 or the front crosspieces 48 to the front louvers 60. The front louvers 60 are horizontal louvers. The front louvers 60 have multiple vertical crosspieces 61 and multiple slats 62.

[0045] The vertical bars 61 of the front louvers 60 are similar to the vertical bars 51 of the side louvers 50. These vertical bars 61 extend parallel to each other in the vertical direction and are arranged horizontally at intervals. The vertical length of the vertical bars 61 is set to match the vertical size of the hanging shelf 18. In other words, the larger the vertical size of the hanging shelf 18, the longer the vertical length of the vertical bars 61. The slats 62 of the front louvers 60 are similar to the slats 52 of the side louvers 50. These slats 62 extend parallel to each other in the horizontal direction and are arranged vertically at equal intervals along the vertical bars 61. The number of slats 62 is set to match the vertical size of the hanging shelf 18. In other words, the larger the vertical size of the hanging shelf 18, the more slats 62 there are. The spacing between the slats 62 of the front louvers 60 is equal to the spacing between the slats 52 of the side louvers 50. The spacing between the slats 62 of the front louvers 60 may be constant regardless of the vertical size of the hanging shelf 18. The slats 62 of the front louvers 60 are fixed to the vertical bars 61 in the same way that the slats 52 of the side louvers 50 are fixed to the vertical bars 51. The intersections between the slats 62 and the vertical bars 61 may be provided in the same manner as the intersections between the slats 52 and the vertical bars 51 of the side louvers 50. The slats 62 have a thickness in the direction in which the vertical bars 61 extend. The upper ends of the vertical bars 61 are aligned with the upper surface of the uppermost slat 62 or are located below that position. The lower ends of the vertical bars 61 are aligned with the lower surface of the lowermost slat 62 or are located above that position.

[0046] The front louvers 60 are attached to the front of the main body frame 40 as follows. The hook 70 is fixed to the upper part of the back surface of the vertical crosspiece 61 with a screw, and the hook 70 is hooked onto the front crosspiece 48 from above. The hook 70 is elastically deformed by the front crosspiece 48 so as to open slightly, and the hook 70 clamps the front crosspiece 48 from the front and rear due to its elastic force. The fixed position of the hook 70 may be adjustable up and down relative to the vertical crosspiece 61.

[0047] The vertical beam 61 to which the hook 70 is attached is the central vertical beam 61 among the multiple vertical beams 61 arranged in the horizontal direction. In other words, the hook 70 is attached to all of the horizontally arranged vertical beams 61 except for the leftmost and rightmost vertical beams 61. The leftmost and rightmost vertical beams 61 are arranged in front of the vertical members 45 of the left and right side frames 41. As shown in FIGS. 3 and 8 , magnets 80 are attached to the front of the left and right vertical members 45, respectively, and the leftmost and rightmost vertical beams 61 are attracted to the magnets 80. If the vertical beams 61 themselves are not magnetic, a magnetic material may be attached to the vertical beam 61 and attracted to the magnet 80. Alternatively, the magnets 80 may be attached to the back of the rightmost and leftmost vertical beams 61, respectively, and the left and right vertical members 45 or the magnetic material attached thereto may be attracted to the magnets 80.

[0048] As described above, the hooks 70 are hooked onto the front crosspieces 48, and the rightmost and leftmost vertical crosspieces 61 are attracted to the left and right vertical members 45 by the magnetic attraction of the magnets 80, thereby attaching the front louvers 60 to the front of the main body frame 40. Note that instead of the magnets 80, suckers (suction cups) may be attached to either the vertical crosspieces 61 or the vertical members 45, with the other being attracted to the sucker. Examples of the suction part include the magnets 80 and suckers, but suction parts other than the magnets 80 and suckers may also be used.

[0049] Because the hook 70 is hooked onto the front crosspiece 48 from above, the front crosspiece 48 serves as a support shaft, allowing the hook 70 to rotate around the central axis of the front crosspiece 48, as shown in Figures 10 and 12. By rotating the hook 70 around the central axis of the front crosspiece 48, the front louver 60 tilts so as to be swung down or up.

[0050] The hooks 70 are provided as follows so that the front louvers 60 can be easily maintained in a vertical position and so that the front louvers 60 can be easily maintained in a raised position swung up at a predetermined angle from the vertical position.

[0051] The hook 70 is made of metal such as stainless steel or aluminum alloy, etc. As shown in FIG.

[0052] The base 71 is formed in the shape of a strip. The base 71 is placed against the upper back surface of the vertical bar 61 and fixed to the vertical bar 61 with screws 78. The screws 78 reach the slats 62, which are fixed to the vertical bar 61 with the screws 78. The screws 78 are passed through holes 75 formed in the base 71, and the vertical size of the holes 75 may be larger than the horizontal size of the holes 75. In this way, when the screws 78 are loosened, the fixed position of the hooks 70 relative to the vertical bar 61 can be adjusted. By adjusting the fixed position of the hooks 70, the height of the slats 62 of the front louvers 60 can be adjusted to the height of the slats 52 of the side louvers 50.

[0053] The bent piece 72 is bent rearward from the upper end of the base 71, perpendicular to the base 71. The first leaf spring 73 is bent upward from the rear edge of the bent piece 72, diagonally relative to the bent piece 72. The second leaf spring 74 is bent downward from the rear edge of the first leaf spring 73, diagonally relative to the bent piece 72 and perpendicular to the first leaf spring 73.

[0054] When the front louver 60 is in a vertical position, the bent piece 72 is in surface contact with the upper surface of the front crosspiece 48, the upper part of the base 71 is in surface contact with the front surface of the front crosspiece 48, and the corner between the upper surface and the front surface of the front crosspiece 48 fits into the recessed corner between the bent piece 72 and the base 71. The first leaf spring 73 is oblique to the upper surface of the front crosspiece 48, raised above the upper surface of the front crosspiece 48, and inclined upward toward the rear. The second leaf spring 74 wraps around from the rear edge of the first leaf spring 73 behind the front crosspiece 48 and is pressed against the corner between the upper surface and the back surface of the front crosspiece 48 from diagonally above and behind by the elastic forces of the first leaf spring 73 and second leaf spring 74. The corner between the top surface and front face of the front crosspiece 48 fits into the recessed corner between the bent piece 72 and the base 71, and the second leaf spring 74 and the base 71 sandwich the front crosspiece 48 between them by their elastic force, so that the front louver 60 is likely to maintain a vertical posture.

[0055] When the front louvers 60 are swung up, the bent pieces 72 lift off the top surfaces of the front crosspieces 48, the upper portions of the bases 71 move away from the front surfaces of the front crosspieces 48, and the corners between the top and front surfaces of the front crosspieces 48 move out of the recessed corner between the bent pieces 72 and the bases 71. The first leaf springs 73 lie face-down against the top surfaces of the front crosspieces 48, and the second leaf springs 74 come into surface contact with the rear surfaces of the front crosspieces 48, so that the corners between the top and rear surfaces of the front crosspieces 48 fit into the recessed corner between the first leaf springs 73 and the second leaf springs 74. At this time, the restoring forces of the first leaf springs 73 and the second leaf springs 74 give a clicking sensation to the person lifting the front louvers 60. By having the corners between the top and rear surfaces of the front crosspieces 48 fit into the recessed corner between the first leaf springs 73 and the second leaf springs 74, the front louvers 60 are more likely to maintain their swung-up position, and the force supporting the front louvers 60 is reduced.

[0056] 12 , the first leaf spring 73 may not be bent from the rear edge of the bent piece 72, but the bent piece 72 may extend from the front edge to the rear edge of the upper surface of the front crosspiece 48, so that the bent piece 72 is in surface contact with the upper surface of the front crosspiece 48, and the leaf spring 74A may be bent vertically downward from the rear edge of the bent piece 72, so that the leaf spring 74A is in contact with the back surface of the front crosspiece 48. To make it easier to insert the front crosspiece 48 between the leaf spring 74A and the base 71, the distance from the leaf spring 74A to the base 71 may be slightly larger than the front-to-rear width of the front crosspiece 48. When the hook 70, which is composed of the base 71, bent piece 72, and leaf spring 74A, is hooked onto the front crosspiece 48, the bent piece 72 and leaf spring 74A elastically deform when the front louvers 60 are swung up, widening the distance between the leaf spring 74A and the base 71. This increases the load required to swing up the front louvers 60. When the front louvers 60 are swung up almost horizontally, the front crosspieces 48 are sandwiched between the leaf springs 74A and the bases 71, and the bases 71 come into surface contact with the upper surfaces of the front crosspieces 48. This surface contact contributes to reducing the force supporting the front louvers 60 in the swung-up position.

[0057] <3. How to set up the blindfold> The side frames 41, side louvers 50, and front louvers 60 are assembled at a factory or installation site. At the factory or installation site, hooks 70 are attached to the vertical bars 61 of the front louvers 60. At the factory or installation site, magnets 80 or suction parts such as suckers are attached to the front of the vertical members 45 of the side frames 41 or the back of the vertical bars 61 of the front louvers 60.

[0058] The side louver 50 is attached to the left side surface of the left side frame 41. If necessary, the second side louver is attached to the right side surface of the right side frame 41. Note that the left side louver 50 may not be attached to the left side frame 41, and the second right side louver may be attached to the right side surface of the right side frame 41. Also, it is not necessary to attach both side louvers.

[0059] The base material 42 of the right side frame 41 is placed against the first wall 11 on the right side of the indoor unit 19, and the base material 42 and the vertical member 45 are adjusted to a vertical position, and the upper arm 43 and the lower arm 44 are adjusted to a horizontal position. Then, the base material 42 is fixed to the first wall 11 with screws or the like. Note that before assembling the right side frame 41, the base material 42 may be fixed to the first wall 11 on the right side of the indoor unit 19. After that, the upper arm 43 and the lower arm 44 may be assembled to the upper end and lower end of the base material 42, respectively, and then the upper end and lower end of the vertical member 45 may be assembled to the upper arm 43 and the lower arm 44, and then the second side louver may be attached to the right side frame 41.

[0060] Next, lift the front crosspiece 48 in front of the indoor unit 19, and insert the joint of the right side frame 41 into the opening at the right end of the front crosspiece 48. Next, lift the left side frame 41 to the left side of the indoor unit 19, and insert the joint of the left side frame 41 into the opening at the left end of the front crosspiece 48.

[0061] Next, the base material 42 of the left side frame 41 is placed against the first wall 11 on the left side of the indoor unit 19, and the base material 42 and the vertical member 45 are adjusted to a vertical position, and the upper arm 43 and the lower arm 44 are adjusted to a horizontal position. After that, the base material 42 is fixed to the first wall 11 with screws or the like.

[0062] Next, the front louvers 60 are lifted up, and the hooks 70 are hooked onto the front crosspieces 48 from above. The front louvers 60 are hung down from the front crosspieces 48, and the vertical members 45 of the side frames 41 or the vertical crosspieces 61 of the front louvers 60 are sucked onto the suction portions.

[0063] If necessary, the relative fixing position of the hook 70 to the vertical bar 61 is adjusted in the vertical direction to align the height of the blades 62 of the front louvers 60 with the height of the blades 52 of the side louvers 50. Finally, one end of the flexible wire 90 is connected to the side frame 41 or the front crosspiece 48 , and the other end of the flexible wire 90 is connected to the front louver 60 .

[0064] <4. Summary> (1) If a pair of side frames 41 are attached to the first wall 11 on both sides of the indoor unit 19, a front crosspiece 48 is placed between the pair of side frames 41, and a front louver 60 is attached to the front of the pair of side frames 41 and the front crosspiece 48, the indoor unit 19 will be concealed by the concealing body 30. Such a concealing body 30 is easy to install. Such a concealing body 30 is suitable for concealing various types of objects attached to a wall in addition to the indoor unit 19, and the concealing body 30 is highly versatile.

[0065] (2) The top, bottom and left side of the concealing body 30 are open, the front of the concealing body 30 is formed by the front louver 60, and the left side of the concealing body 30 is formed by the side louver 50, so the concealing body 30 does not obstruct the intake and exhaust of air from the indoor unit 19.

[0066] (3) The concealing body 30 covers the indoor unit 19. Such a concealing body 30 contributes to improving the aesthetic appearance of the living room, dining room, and kitchen.

[0067] (4) By hooking the hook 70 onto the front crosspiece 48 from above, the front louvers 60 can be easily attached to the front of the front crosspiece 48 and the side frame 41.

[0068] (5) Even if the hook 70 comes off the front crosspiece 48, the front louver 60 is suspended from the main body frame 40 by the flexible wire 90. This prevents the front louver 60 from falling to the floor.

[0069] (6) The front louvers 60 are supported on the main body frame 40 not only by the hooks 70 but also by an adhesive portion such as the magnets 80. Therefore, the front louvers 60 are stable and are prevented from falling off.

[0070] (7) Because the hook 70 is hooked onto the front crosspiece 48 so as to be rotatable around the central axis of the front crosspiece 48, the front louvers 60 can be swung up and down. When the front louvers 60 are swung up, the front of the indoor unit 19 is opened, making it easy to handle the indoor unit 19, such as for cleaning or maintenance.

[0071] (8) When the front louvers 60 are swung down, the bases 71 are in surface contact with the front surfaces of the front crosspieces 48, the bent pieces 72 are in surface contact with the upper surfaces of the front crosspieces 48, and the second leaf springs 74 are placed against the rear of the front crosspieces 48, so that the hooks 70 are hooked onto the front crosspieces 48 and the front louvers 60 are supported by the front crosspieces 48. The first leaf springs 73 and second leaf springs 74 are used, and the first leaf springs 73 are floating above the upper surfaces of the front crosspieces 48, so that the front louvers 60 can be easily swung up from the down state.

[0072] (9) When the front louvers 60 are swung up, with the second leaf springs 74 abutting against the rear of the front crosspieces 48, the bent pieces 72 move away from the top surfaces of the front crosspieces 48, the bases 71 move away from the front surfaces of the front crosspieces 48, the first leaf springs 73 abut against the top surfaces of the front crosspieces 48, and the corners between the top and rear surfaces of the front crosspieces 48 fit into the recessed corners between the first leaf springs 73 and the second leaf springs 74. At this time, the restoring forces of the first leaf springs 73 and the second leaf springs 74 give a clicking sensation to the person lifting the front louvers 60.

[0073] (10) When the front louvers 60 are in the raised position, the bent pieces 72 are spaced apart from the upper surfaces of the front rails 48, so that the front louvers 60 can be easily lowered from the raised position.

[0074] (11) When the front louvers 60 are swung down, with the second leaf springs 74 abutting the rear of the front crosspieces 48, the base 71 abuts the front of the front crosspieces 48, the bent pieces 72 abut the top surfaces of the front crosspieces 48, and the first leaf springs 73 move away from the top surfaces of the front crosspieces 48. The corner between the front and top surfaces of the front crosspieces 48 fits into the recess between the base 71 and the bent pieces 72, which gives a clicking sensation to the person swinging the front louvers 60 down.

[0075] (12) The screws 78 are used to fasten the hooks 70 to the vertical bars 61 and the slats 62 to the vertical bars 61. This reduces the number of parts of the privacy screen 30.

[0076] (13) By loosening the screws 78, the relative fixed position of the hooks 70 with respect to the vertical bars 61 can be adjusted to align the height of the slats 62 of the front louvers 60 with the height of the slats 52 of the side louvers 50.

[0077] (14) Because the front crosspiece 48 is bridged between the upper ends of the pair of side frames 41 in front of the indoor unit 19, the front crosspiece 48 does not interfere with ducts or the like that are piped to the indoor unit 19. In addition, the air blown out by the indoor unit 19 does not directly hit the front crosspiece 48, and condensation is less likely to occur on the surface of the front crosspiece 48, so corrosion of the front crosspiece 48 is less likely to occur.

[0078] (15) The slats 52, 62 of the louvers 50, 60 are made of wood. The energy used from production to disposal and discarding of wood is less than the energy used from production to disposal and discarding of metal or concrete materials. Therefore, the privacy screen 30 made of wood contributes to the realization of a decarbonized society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and to the achievement of the Sustainable Development Goals (SDGs).

[0079] (16) The above-disclosed embodiments have been made for the purpose of illustration and example only, and are not intended to limit the scope of the present invention, which is defined by the claims. [Explanation of symbols]
