Embodiments for Carrying Out the Invention

[0009] Embodiments of the mounting device according to the present invention will be described with reference to the accompanying drawings.

[0010] In the following description, "upper", "lower", "right", "left", "indoor" and "outdoor" follow the definitions in FIGS. 1 to 15. The vertical direction means the up and down direction. The direction including the left and right direction and the indoor-outdoor direction (the direction connecting the indoor and the outdoor) is defined as the horizontal direction.

[0011] FIG. 1 is an external perspective view of a mounting device 1 which is an embodiment of the mounting device according to the present invention.

[0012] FIG. 2 is an external perspective view of the mounting device 1 in a state of being attached to the frame 4.

[0013] FIG. 3 is an external perspective view of the mounting device 1 in a state where the air conditioner 5 is attached.

[0014] FIG. 4 is an explanatory diagram of the window 2 and the frame 4 to which the air conditioner 5 is attached.

[0015] The mounting device 1 is a device used to mount equipment on the window 2. As shown in FIG. 4, for example, the mounting device 1 is used to mount the window air conditioner 5 (hereinafter simply referred to as the air conditioner 5) used with the window 2 partially opened on the frame 4. The frame 4 is a frame member that surrounds the window 2 and separates (divides) the window 2 from the inner wall. The frame 4 is disposed on the indoor side with respect to the window 2 and the sash 3 of the window 2, and has a pair of upper and lower frame members 4a, 4b of the frame and a pair of vertical frame members 4c of the frame. The frame 4 has a constant width in the indoor-outdoor direction.

[0016] The mounting device 1 mainly includes a frame member 10, a panel member 30, a lower fixture 40, an upper fixture 50, and a covering member 90.

[0017] The frame member 10 has an upper frame 11 (a pair of upper and lower frames), a lower frame 12 (a pair of upper and lower frames), a pair of vertical frames 13, and a middle frame 14. The frame member 10 is made of a material having a required strength (such as a metal such as a zinc-plated steel plate).

[0018] The upper frame 11 is disposed above the frame member 10 along the left-right direction in parallel with the pair of upper and lower frame members 4a, 4b of the frame. The upper frame 11 has an upper surface 11a on which the upper fixture 50 is disposed.

[0019] The lower frame 12 is disposed below the frame member 10 along the left-right direction in parallel with the pair of upper and lower frame members 4a, 4b of the frame. The lower frame 12 serves as a pedestal for the air conditioner 5 supported by the mounting device 1.

[0020] The pair of vertical frames 13 are disposed along the vertical direction in parallel with the pair of vertical frame members 4c of the frame. The pair of vertical frames 13 have an inner vertical frame 16, an outer vertical frame 17, and a tightening screw 18. The outer vertical frame 17 has a space for accommodating the inner vertical frame 16 movably in the vertical direction inside. The inner vertical frame 16 is accommodated movably in the vertical direction inside the outer vertical frame 17 such that the upper end 16a protrudes from the upper end 17a of the outer vertical frame 17. The tightening screw 18 fixes the inner vertical frame 16 at a required position by fastening the outer vertical frame 17 and the inner vertical frame 16 from the indoor side. Thereby, the pair of vertical frames 13 are stretchable in the vertical direction.

[0021] The middle frame 14 is arranged along the left - right direction parallel to the upper frame 11 and the lower frame 12. The middle frame 14 is fixed by being spanned over the upper ends 17a of the pair of outer vertical frames 17.

[0022] The panel member 30 is arranged to block the space between the upper frame 11 and the middle frame 14 in the indoor - outdoor direction where the air conditioner 5 in the frame member 10 is not arranged. Since the upper end of the panel member 30 is fixed to the upper frame 11 and the lower end is fixed to the middle frame 14 and has an accordion shape, the vertical length can be made variable according to the length of the vertical frame 13.

[0023] The lower fixture 40 is arranged below the frame member 10 and along the left - right direction between the frame member 10 and the picture - frame lower frame 4b. Here, FIG. 5 is a view particularly explaining the lower fixture 40 seen from the left side.

[0024] The lower fixture 40 has an adjustment part 41, an anti - slip part 42, and a packing 43.

[0025] The adjustment part 41 is fixed to the lower surface of the lower frame 12 and adjusts the height of the mounting device 1 from the picture - frame lower frame 4b. The adjustment part 41 has an upper block 41a and a lower block 41b. The upper block 41a is fixed to the lower surface of the lower frame 12, for example, by screws. The lower block 41b is fixed to the lower surface of the upper block 41a by a fitting structure with, for example, left - right sliding.

[0026] The anti - slip part 42 is arranged below the adjustment part 41 and is used as an anti - slip between the adjustment part 41 and the picture - frame lower frame 4b.

[0027] The packing 43 is made of, for example, soft vinyl chloride, etc., and prevents rainwater hitting the back of the air conditioner 5 exposed to the outdoor side from entering the indoor side through the gap between the sash 3 and the mounting device 1. One end of the packing 43 is fixed to the upper block 41a, for example, and the other end extends beyond the innermost indoor - side rising 3a of the sash 3 and hangs down into the groove formed between the risings 3a.

[0028] The lower fixture 40 can adjust the height of the lower frame 12 with the adjustment part 41 from the viewpoint of preventing rainwater from entering the indoor side. That is, when the sash 3 of the window 2 has a rise 3a, the position of the lower frame 12 is raised by using the upper block 41a and the lower block 41b so that the lower frame 12 is located above the sash 3 of the window 2. Thereby, one end of the packing 43 becomes higher than the rise 3a, and the packing 43 can be arranged so as to cover the rise 3a, preventing rainwater from entering the indoor side. On the other hand, in the case of the sash 3 without the rise 3a, since it is not necessary to raise the position of the lower frame 12, only the upper block 41a can be used.

[0029] The upper fixture 50 is detachably arranged at two positions on the left and right end sides of the upper surface 11a of the upper frame 11. The upper fixture 50 has a tensioning mechanism that tensions the frame member 10 in the vertical direction (longitudinal direction) with respect to the pair of picture frame upper and lower frames 4a, 4b, and fixes the frame member 10 that holds the air conditioner 5 to the picture frame 4 by the tensioning force generated by this tensioning mechanism. Specifically, with the tensioning mechanism, the pair of vertical frames 13 extend in the vertical direction, and the upper surface (contact surface 65) of the upper fixture 50 arranged at the upper end of the mounting device 1, that is, the uppermost part of the mounting device 1, contacts the picture frame upper frame 4a (the upper picture frame upper and lower frame), and further extends in the vertical direction to tension the frame member 10 in the vertical direction.

[0030] Here, FIG. 6 is a perspective view showing the upper fixture 50 from the indoor side. FIG. 7 is a perspective view showing the upper fixture 50 with the cover 67 removed from the outdoor side. FIG. 8 is a longitudinal sectional view of the mounting device 1 in FIG. 1 including the input screw 74, showing a state where the tensioning mechanism is not acting. FIG. 9 is a longitudinal sectional view of the mounting device 1 in FIG. 1 including the input screw 74, showing a state where the tensioning mechanism is acting.

[0031] The upper fixture 50 includes a case 51, a lower slide member 55, an upper slide member 58, a protruding member 63, a cover 67, an input screw 74, and a lock member 78.

[0032] Case 51 appears in a sectional L-shape in FIGS. 8 and 9 and is a member made of, for example, resin that has openings on the upper side and the outdoor side as shown in FIG. 7. Case 51 houses the lower slide member 55 and the upper slide member 58 in its internal space. Case 51 has claw portions 52 on its left and right side surfaces that fit with the cover 67. Further, Case 51 has an input screw hole 53 and a fixing screw hole 54 on the indoor side surface 51b. The input screw hole 53 allows the input screw 74 inserted from the indoor side to penetrate into the internal space. The fixing screw hole 54 is a hole that receives the fixing screw 66 for fixing the upper fixture 50 to the upper frame 11.

[0033] The lower slide member 55 has a triangular prism shape that appears in a sectional trapezoid shape in FIGS. 8 and 9 and is made of, for example, resin. The lower slide member 55 is disposed on the bottom surface 51c of the case 51. The lower slide member 55 has a length in the indoor-outdoor direction that is smaller than the length in the indoor-outdoor direction of the internal space of the case 51 and is movable in the indoor-outdoor direction. The lower slide member 55 has a lower slide surface 56 and a screw receiving portion 57. The lower slide surface 56 faces upward and is a surface inclined such that the outdoor side is positioned downward with respect to the horizontal direction. The screw receiving portion 57 is disposed on the indoor side surface 55a and receives the tip 74a of the input screw 74.

[0034] The upper slide member 58 is disposed above the lower slide member 55 and is made of, for example, resin. The upper slide member 58 has an upper slide surface 59, a screw fastening portion 60, and a connecting portion 61. The upper slide surface 59 faces downward and is a surface inclined such that the outdoor side is positioned downward with respect to the horizontal direction and is a surface parallel to the inclination of the lower slide surface 56. The screw fastening portion 60 is disposed on the outdoor side of the upper slide member 58. The screw fastening portion 60 has a screw hole 62 for fastening the screw 92 that fixes the covering member 90. The connecting portion 61 connects and holds the protruding member 63 in a fitting structure.

[0035] The protruding member 63 is disposed above the upper slide member 58 and has a rectangular parallelepiped shape. The protruding member 63 has a concave portion 64 and a contact surface 65. The concave portion 64 is a portion formed to be concave upward and fitting into the connecting portion 61 of the upper slide member 58. The contact surface 65 is a surface facing upward and substantially parallel to the frame upper frame 4a. As the upper slide member 58 ascends, it moves upward, comes into close contact with the frame upper frame 4a, and is a surface that applies a tension force. The contact surface 65 generates a horizontal frictional force with respect to the frame 4 for holding the air conditioner 5 and the mounting device 1 so that the mounting device 1 holding the air conditioner 5 does not fall from the frame 4. For this reason, the contact surface 65 is made of a material having a required frictional force with respect to the frame 4 and having a buffering property such that it does not damage the frame upper frame 4a when contacting the frame upper frame 4a. The contact surface 65 can be formed from various materials such as rubber, felt, silicone, sponge, urethane, etc. Also, only the contact surface 65 may be formed from these materials, or the entire protruding member 63 may be formed from these materials.

[0036] The cover 67 is open downward so as to cover the case 51 housing the lower slide member 55, the upper slide member 58, and the protruding member 63 from above. The cover 67 is fixed to the case 51 by engaging with the claw portion 52 of the case 51. The cover 67 has a protruding portion opening 68, a screwing portion opening 69, a screw cutting hole 70 for an input screw, a screw cutting hole 71 for a fixing screw, and a lock member restricting portion 72.

[0037] The protruding portion opening 68 is formed in the upper surface 67a and is an opening for protruding the protruding member 63 upward from the case 51. The screwing portion opening 69 is formed in the outdoor side surface 67c and is an opening for protruding the screwing portion 60 of the upper slide member 58 to the outdoor side from the case 51.

[0038] The screw cutting hole 70 for an input screw is a hole with a female screw processed for fastening with the input screw 74 inserted from the indoor side. The screw cutting hole 71 for a fixing screw is a hole with a female screw processed for fastening with the fixing screw 66 inserted from the indoor side.

[0039] The lock member restricting portion 72 is a sheet-like portion bent downward at a substantially right angle from the upper surface 67a, and by being inserted into the restricting hole 81 of the corresponding lock member 78, it restricts the range of movement of the lock member 78 in the left-right direction on the case 51.

[0040] The input screw 74 acts as an input portion that receives force from the user. Specifically, the input screw 74 receives a rotational force around an axis along the inside-outside direction from the indoor side to the outdoor side from the user, and moves in the inside-outside direction to transmit force to the lower slide member 55 as a conversion portion. The input screw 74 has a flat portion 75 on the tip 74a side opposite to the screw head. The flat portion 75 is a portion symmetrically notched with respect to the screw axis so as to form a flat surface having a predetermined length in the screw axis direction. By being notched, the flat portion 75 periodically generates a region that does not mesh with the screw-cutting hole 70 for the input screw during rotation at the time of fastening.

[0041] The lock member 78 can lock the rotation of the input screw 74 by sliding in the left-right direction on the case 51. The lock member 78 is made of, for example, a metal having a required strength. The lock member 78 has a lock hole 79, a knob 80, and a restricting hole 81.

[0042] The lock hole 79 is formed in the indoor side surface 78a arranged along the indoor side surface 67b of the cover 67, and consists of a rotation region 82 and a lock region 83 arranged continuously in the left-right direction. The rotation region 82 has dimensions that allow the input screw 74 to be rotated. The lock region 83 has dimensions that fit with the flat portion 75 of the input screw 74 and restrict the rotation of the input screw 74. That is, the flat portion 75 of the input screw 74 is designed so that the flat portion 75 is arranged in the lock region 83 when the upper fixture 50 is applying a tension force at the timing when the rotation of the input screw 74 is to be restricted.

[0043] The knob 80 is used when the user moves the lock member 78 in the left-right direction on the case 51.

[0044] The restriction hole 81 is a hole formed in the upper surface 78b (FIG. 7) arranged along the upper surface 51a of the case 51, and has a lateral length substantially the same as the lateral length of the lock hole 79. The lock member restricting portion 72 of the cover 67 is inserted into the restriction hole 81. Thereby, the movement range of the lock member 78 in the lateral direction is restricted by the lock member restricting portion 72.

[0045] The covering member 90 is a member made of, for example, metal, which is arranged to cover the gap between the upper frame 11 and the frame upper frame 4a. The covering member 90 is arranged across the lateral direction of the upper frame 11, and is held by being screwed at two screwing portions 60 of the upper fixture 50. When the sash 3 has the rising portion 3a, the covering member 90 may have a gripping portion 91 for gripping the rising portion 3a. The gripping portion 91 has a form corresponding to the shape and dimensions of the rising portion 3a, and in addition to fixing the mounting device 1 and the air conditioner 5 by the tension force of the upper fixture 50, it can also function as a fall prevention for the mounting device 1 and the air conditioner 5.

[0046] Next, the procedure for attaching the mounting device 1 in the present embodiment to the frame 4 (window 2) will be described.

[0047] The mounting device 1 is arranged on the lower frame 4b of the frame while abutting against the rising portion 3a of the sash 3 after adjusting the height of the lower fixture 40 according to the dimensions of the rising portion 3a of the sash 3 to be mounted. Thereafter, according to the height of the frame 4, the inner vertical frame 16 is extended until the contact surface 65 of the upper fixture 50 contacts the frame upper frame 4a, and the height of the vertical frame 13 is adjusted. When the position of the inner vertical frame 16 is determined, the inner vertical frame 16 is fixed to the outer vertical frame 17 by the tightening screw 18.

[0048] Next, the input screws 74 of the two upper fixtures 50 are rotated in the tightening direction. At this time, the lock member 78 is slid so that the input screw 74 is positioned in the rotation region 82. When the input screw 74 is tightened, the lower slide member 55 as a conversion unit is pushed into the input screw 74 and moves to the outdoor side so as to transition from the state of FIG. 8 to the state of FIG. 9. Then, the upper slide surface 59 that contacts the lower slide surface 56 slides up relative to the lower slide surface 56, and as a result, the upper slide member 58 rises. Also, the protruding member 63 also rises in conjunction, so that the contact surface 65 comes into close contact with the frame upper frame 4a, and a tensile force is generated between the frame upper and lower frames 4a, 4b and the mounting device 1. That is, the lower slide member 55, the upper slide member 58, and the protruding member 63 function as a conversion unit that converts the force received from the input screw 74 as an input unit into a force that the mounting device 1 vertically stretches against the frame 4.

[0049] Thereafter, the lock member 78 is slid to the left, the flat portion 75 fits into the lock region 83, and the rotation of the input screw 74 in the loosening direction is restricted. Thereby, it is possible to suppress a decrease in the tensile force due to loosening of the input screw 74.

[0050] Such a mounting device 1 in the present embodiment has a higher degree of freedom regarding the mounting destination compared to a conventional mounting device that is fixed to the frame 4 via the rising 3a of the sash 3 by the fastening force of screws in the indoor-outdoor direction, or a mounting device that is directly fixed to the frame 4 using screws or the like.

[0051] Here, FIG. 10 is an example of a conventional mounting device 101 and shows the vicinity of the upper frame 111. FIG. 11 is a diagram for explaining the mounting device 101 of FIG. 10 in a state where it is arranged on the frame 4.

[0052] In the conventional mounting device 101, the pair of upper and lower frames 111 and 112 have a fitting portion 113 and a tightening screw 114 as a fastening member. The fitting portion 113 is a groove formed between two rising portions 115 on the outdoor side of the upper and lower frames 111 and 112. The fitting portion 113 is a vertical (from bottom to top, from top to bottom) rise arranged on the outdoor side with respect to the frame 4, and for example, receives the rise 3a of the sash 3 and fits with the rise 3a. The tightening screw 114 fixes the fitting of the rise 3a and the fitting portion 113 by a fastening force. Specifically, the tightening screw 114 has a screw axis along the indoor-outdoor direction, and by tightening from the indoor side, the rise 3a of the sash 3 is sandwiched and fixed together with the rising portion 115 arranged on the outermost outdoor side of the upper and lower frames 111 and 112.

[0053] Such a mounting device 101 requires a height sufficient to sandwich and fasten the rise 3a with the tightening screw 114 and the fitting portion 113. Therefore, when the height of the rise 3a is insufficient, the mounting device 101 cannot be mounted. Further, since the mounting device 101 is mounted on the frame 4 via the rise 3a, the load of the mounting device 101 and the air conditioner 5 is applied to the rise 3a. Therefore, the mounting device 101 cannot be mounted on a rise 3a (for example, a steel or wooden sash 3) that does not have sufficient strength to withstand this.

[0054] Also, in the case of a sash 3 with insufficient height or strength of the rise 3a, by attaching a separately prepared reinforcing metal fitting to the frame 4 or the sash 3, the mounting device 101 can be mounted via the reinforcing metal fitting instead of the rise 3a. However, for example, when there are restrictions on drilling holes in facilities such as rental properties, the reinforcing metal fitting cannot be attached, and the mounting device 101 still cannot be attached.

[0055] In contrast, the mounting device 1 in the present embodiment fixes the mounting device 1 to the frame 4 (window 2) by utilizing the vertical tension force (frictional force) between the mounting device 1 and the frame 4. Therefore, regarding the mounting destination of the mounting device 1, the mounting device 1 can be mounted on any window 2 or sash 3 as long as the frame 4 has a dimension in which the mounting device 1 can be arranged.

[0056] Also, the mounting device 1 in the present embodiment can be mounted on the upper and lower frames 111 and 112 of the conventional mounting device 101 as shown in FIGS. 10 and 11 by designing the upper fixture 50 (lower fixture 40) to an appropriate dimension. Therefore, the mounting device 1 in the present embodiment can also be realized by attaching the upper fixture 50 (lower fixture 40) to the conventional mounting frame. For example, remove the tightening screw 114, arrange the upper fixture 50 in the space formed between the outdoor rising portions 115 of the upper frame 111, and fix the upper fixture 50 to the most indoor rising portion 115 with the fixing screw 66. Also, fix the lower fixture 40 to the lower frame 112. Thereby, the mounting device 1 can be formed using the mounting frame of the conventional mounting device 101.

[0057] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the claims. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and its equivalent scope.

[0058] For example, although the example in which the tension mechanism is the upper fixture 50 has been described, as shown in FIG. 12, a fixture 201 having the same configuration as the upper fixture 50 may be arranged as a tension mechanism between the lower frame 12 and the lower frame 4b of the frame, and the mounting device 1 may be fixed by the tension force.

[0059] Alternatively, as shown in FIG. 13, a tension mechanism may be realized by generating a tension force using the elastic force of an elastic body such as the spring 211. This tension mechanism includes the spring 211, the protruding member 212, the opening / closing member 214, and the case 215. One end of the spring 211 is fixed to, for example, the upper frame 11, and the other end is fixed to the lower surface of the protruding member 212. The protruding member 212 has a contact surface 213 on its upper surface that contacts the frame 4. The contact surface 213 has the same function as the contact surface 65 of the protruding member 63 described above. The opening / closing member 214 slides indoors as shown in FIG. 13(b) when using the tension force, and uses the elastic force of the spring 211 to project the protruding member 212 upward. The case 215 houses the spring 211 and is fixed to the upper frame 11. The mounting device 1 is fixed to the frame 4 by the tension force generated between the contact surface 213 of the protruding member 212 and the frame 4.

[0060] Furthermore, the tension mechanism may be disposed inside the vertical frame 13 in addition to between the upper and lower frames 11, 12 and the upper and lower frame edges 4a, 4b. FIG. 14 is a longitudinal sectional view of the vertical frame 13 including the tightening screw 18 of FIG. 1. The tension mechanism in FIG. 14 has a serrated uneven surface 221 and a pushing-up member 224 on the inner surface of the inner vertical frame 16.

[0061] The uneven surface 221 has a plurality of upper slide surfaces 222 that are inclined downward on the indoor side with respect to the horizontal direction. The pushing-up member 224 is disposed inside the inner vertical frame 16 in a state of being disposed on the end 18a side opposite to the screw head of the tightening screw 18.

[0062] The pushing-up member 224 is provided with a female screw process for fastening to the fastening screw 18 that fixes the outer vertical frame 17 and the inner vertical frame 16. The pushing-up member 224 has a lower slide surface 225 whose indoor side is inclined downward with respect to the horizontal direction. The lower slide surface 225 is a surface parallel to the upper slide surface 222 of the uneven surface 221. When the inner vertical frame 16 moves up and down with respect to the outer vertical frame 17, the pushing-up member 224 may be caught by the tip 224a side on the indoor side on the uneven surface 221. For this reason, it is preferable that the pushing-up member 224 has a mechanism (for example, a ratchet mechanism) such that, when it comes into contact with the inner vertical frame 16, for example, the tip 224a portion retracts in the outdoor direction.

[0063] When the position of the inner vertical frame 16 with respect to the outer vertical frame 17 is determined and the fastening screw 18 is tightened, the pushing-up member 224 moves to the indoor side. Then, the lower slide surface 225 of the pushing-up member 224 comes into contact with the upper slide surface 222 of the contacting uneven surface 221, and further pushes up the inner vertical frame 16 via the upper slide surface 222. As a result, the contact portion (not shown) with the frame 4 disposed on the upper frame 11 comes into close contact with the frame upper frame 4a, and a tensile force is generated between the frame upper frame 4a and the mounting device 1.

[0064] The tensioning mechanism described in FIG. 14 in this way can also use the fastening force of the fastening screw 18 that fixes the outer vertical frame 17 and the inner vertical frame 16 for generating the tensile force.

[0065] Further, the tensioning mechanism may be disposed inside the outer vertical frame 17 and near the lower end 16b of the inner vertical frame 16. FIG. 15 is a longitudinal sectional view including the vicinity of the lower end 16b of the inner vertical frame 16. The tensioning mechanism in FIG. 15 generates a tensile force at the lower end 16b of the inner vertical frame 16 by the same action as the tensile force generated by the input screw 74, the lower slide member 55, and the upper slide member 58 described above.

[0066] Specifically, the tensioning mechanism includes a case 231, an input screw 232, a lower slide member 233, and an upper slide member 234. The case 231 houses the lower slide member 233 and the upper slide member 234. The case 231 is supported in advance by the lower end 16b of the inner vertical frame 16. When the position of the case 231 relative to the outer vertical frame 17 of the inner vertical frame 16 is determined, the case 231 is fastened to an input screw 232 inserted into an appropriate screw hole among a plurality of screw holes provided on the indoor side surface 17b of the outer vertical frame 17, and is fixedly attached to the lower end 16b of the inner vertical frame 16.

[0067] The input screw 232, the lower slide member 233, and the upper slide member 234 have substantially the same functions as the above-described upper fixture 50, and thus detailed descriptions thereof are omitted here.

[0068] Such a tensioning mechanism in FIG. 15 can also convert the upward force generated by the fastening force of the input screw 74 into a tensioning force between the upper and lower frame members 4a and 4b of the frame and the mounting device 1, and the mounting device 1 can be attached to the frame 4 by this tensioning force.

[0069] Note that, although the mounting device according to the present invention has been described by using an example in which the device to be mounted on the mounting device is the air conditioner 5, it can be applied to mount any device or structure installed on a window. For example, even when the mounting device and the device or structure to be mounted are integrated in advance, it can be included in the concept of the mounting device according to the present invention. Further, the mounting device may be a panel-shaped member having, for example, an inner panel and an outer panel that support the device instead of a frame-shaped member. For example, when the device is an exhaust heat duct that is connected to an air conditioner used by being placed on the floor and extends outdoors, a panel-shaped mounting device may be used to penetrate this exhaust heat duct through the panel and attach it to the window.
