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

[0010] In the following explanation, "up," "down," "right," "left," "indoor," and "outdoor" follow the definitions in Figures 1 to 20. The vertical direction refers to the up-down direction. The indoor direction refers to the direction facing the room relative to the window, and the outdoor direction refers to the direction facing the outside relative to the window. The direction that includes the left-right direction and the indoor-outdoor direction (the direction connecting the indoors and outdoors) is defined as the horizontal direction.

[0011] FIG. 1 is a perspective view showing the appearance of an attachment device 1 which is one embodiment of an attachment device according to the present invention.

[0012] FIG. 2 is a perspective view of the appearance of the mounting device 1 attached to the frame 4. As shown in FIG.

[0013] FIG. 3 is a perspective view showing the appearance of the mounting device 1 with the air conditioner 5 mounted thereon.

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

[0015] The mounting device 1 is a device used to mount equipment on a window 2. For example, as shown in FIG. 4, the mounting device 1 is used to mount a window air conditioner 5 (hereinafter simply referred to as the air conditioner 5) to a frame 4, which is used with the window 2 partially open. The frame 4 is a frame material arranged to surround the window 2 and separate (separate) the window 2 from the interior wall. The frame 4 is arranged on the indoor side of the window 2 and its sash 3, and has a pair of upper and lower frame frames 4a, 4b and a pair of vertical frame frames 4c. The frame 4 has a certain width in the indoor-outdoor direction. The sash 3 has a rail 6 for the window 2 and a riser 7. The riser 7 is arranged on the indoor side of the rail 6 and extends vertically from the sash 3. The riser 7 has a vertical length of, for example, 20 to 40 mm, but may be shorter than 20 mm.

[0016] The mounting device 1 mainly includes a frame member 10, a panel member 30, a lower fixing member 40, an upper fixing member 50, and a collapse prevention 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 (for example, a metal such as a galvanized steel sheet).

[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 sections 4a, 4b. The upper frame 11 has an upper surface 11a on which the upper fixing device 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 sections 4a, 4b. The lower frame 12 serves as a base for the air conditioner 5 supported by the mounting device 1.

[0020] The pair of vertical frames 13 are arranged vertically in parallel with the pair of vertical frame frames 4c. The pair of vertical frames 13 includes an inner vertical frame 16, an outer vertical frame 17, and a tightening screw 18. The outer vertical frame 17 has a space inside that accommodates the inner vertical frame 16 so that it can move up and down. The inner vertical frame 16 is accommodated inside the outer vertical frame 17 so that its upper end 16a protrudes from the upper end 17a of the outer vertical frame 17 and can move up and down. The tightening screw 18 fastens the outer vertical frame 17 and inner vertical frame 16 from the inside of the room, thereby fixing the inner vertical frame 16 in the required position. This allows the pair of vertical frames 13 to freely expand and contract vertically.

[0021] The middle frame 14 is disposed along the left-right direction in parallel with the upper frame 11 and the lower frame 12. The middle frame 14 is fixed to and spans the upper ends 17a of a pair of outer vertical frames 17.

[0022] The panel member 30 is arranged to close the space between the upper frame 11 and the middle frame 14 in the indoor / outdoor direction, where the air conditioner 5 is not arranged within the frame member 10. The panel member 30 has an accordion shape with its upper end fixed to the upper frame 11 and its lower end fixed to the middle frame 14, so that its vertical length can be adjusted according to the length of the vertical frame 13.

[0023] The lower fixture 40 is disposed below the frame member 10, between the frame member 10 and the lower frame 4b of the picture frame, along the left-right direction. Here, Fig. 5 is a diagram particularly illustrating the lower fixture 40 as seen from the left.

[0024] The lower fixing device 40 has an adjustment portion 41 , a non-slip portion 42 , and a packing 43 .

[0025] The adjustment unit 41 is fixed to the lower surface of the lower frame 12 and adjusts the height of the mounting device 1 from the lower frame 4b of the picture frame. The adjustment unit 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 by, for example, screws. The lower block 41b is fixed to the lower surface of the upper block 41a by a fitting structure that allows it to slide in the left-right direction, for example.

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

[0027] The packing 43 is made of, for example, soft polyvinyl chloride, and prevents rainwater hitting the rear surface of the air conditioner 5 exposed to the outside from entering the room through the gap between the sash 3 and the mounting device 1. The packing 43 is arranged so that one end is fixed to, for example, the upper block 41a, and the other end exceeds the rising edge 7 of the sash 3 closest to the room and hangs down into the groove formed between the rising edges 7.

[0028] The lower fixing device 40 can adjust the height of the sill 12 using the adjustment part 41 to prevent rainwater from entering the interior of the room. That is, if the sash 3 of the window 2 has a rise 7, the position of the sill 12 is raised by using the upper block 41a and the lower block 41b so that the sill 12 is positioned higher than the sash 3 of the window 2. This makes one end of the gasket 43 higher than the rise 7, allowing the gasket 43 to be positioned to cover the rise 7, preventing rainwater from entering the interior of the room. On the other hand, if the sash 3 does not have a rise 7, there is no need to raise the position of the sill 12, so only the upper block 41a can be used.

[0029] The upper fixing device 50 is detachably arranged at two locations on the left and right ends of the upper surface 11a of the upper frame 11. The upper fixing device 50 has a tensioning mechanism that tensions the frame member 10 in the up-down direction (vertical direction) relative to the pair of upper and lower frame frames 4a, 4b, and the tensioning force generated by this tensioning mechanism fixes the frame member 10 that holds the air conditioner 5 to the frame 4. Specifically, the tensioning mechanism of the upper fixing device 50 causes the pair of vertical frames 13 to extend vertically, and the upper end of the mounting device 1, i.e., the upper surface (contact surface 65) of the upper fixing device 50 arranged at the top of the mounting device 1, contacts the upper frame frame 4a (the upper pair of upper and lower frame frames), and the upper fixing device 50 further extends vertically to tension the frame member 10 vertically.

[0030] Here, Fig. 6 is a perspective view of the upper fixing device 50 from the indoor side. Fig. 7 is a perspective view of the upper fixing device 50 from the outdoor side with the cover 67 removed. Fig. 8 is a vertical cross-section of the mounting device 1 of Fig. 1 including the input screw 74, showing a state in which the tensioning mechanism is not operating. Fig. 9 is a vertical cross-section of the mounting device 1 of Fig. 1 including the input screw 74, showing a state in which the tensioning mechanism is operating.

[0031] The upper fixing device 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 locking member 78 .

[0032] The case 51 is an L-shaped cross section in FIGS. 8 and 9 and is a member made of, for example, resin, with openings on the upper and outdoor sides as shown in FIG. 7. The case 51 houses a lower slide member 55 and an upper slide member 58 in its internal space. The case 51 has claws 52 on its left and right sides that mate with a cover 67. The case 51 also has an input screw hole 53 and a fixing screw hole 54 on its indoor side surface 51b. The input screw hole 53 allows an input screw 74 inserted from the indoor side to pass through into the internal space. The fixing screw hole 54 is a hole that receives a fixing screw 66 for fixing the upper fixing device 50 to the upper frame 11.

[0033] The lower sliding member 55 has a triangular prism shape that appears as a trapezoidal cross section in Figures 8 and 9, and is made of, for example, resin. The lower sliding member 55 is placed on the bottom surface 51c of the case 51. The lower sliding member 55 has an indoor / outdoor length that is shorter than the indoor / outdoor length of the interior space of the case 51, and is movable indoors and outdoors. The lower sliding member 55 has a lower sliding surface 56 and a screw receiving portion 57. The lower sliding surface 56 faces upward and is inclined relative to the horizontal direction so that the outdoor side is positioned downward. The screw receiving portion 57 is placed 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 inclined relative to the horizontal direction so that the outdoor side is positioned downward, 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 a screw 92 that secures the tip-prevention member 90. The connecting portion 61 connects and holds the protruding member 63 by 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 recess 64 and a contact surface 65. The recess 64 is a portion formed to be concave upward and fit into the connecting portion 61 of the upper slide member 58. The contact surface 65 is disposed above the protruding member 63 so as to face upward, and is a surface approximately parallel to the upper frame 4a of the frame. The contact surface 65 moves upward as the upper slide member 58 rises, protrudes from the cover 67, and comes into close contact with the upper frame 4a of the frame, generating a tension force between the upper frame 4a and the frame member 10. The contact surface 65 generates a horizontal friction force against the frame 4 that holds the air conditioner 5 and the mounting device 1 to prevent the mounting device 1 that holds the air conditioner 5 from falling off the frame 4. For this reason, the contact surface 65 is made of a material that has a required frictional force with the frame 4 and cushions the upper frame 4a so as not to damage it when it comes into contact with the upper frame 4a. The contact surface 65 can be made of various materials, such as rubber, felt, silicone, sponge, or urethane. Only the contact surface 65 may be made of these materials, or the entire protruding member 63 may be made of these materials. The upper slide member 58 and the protruding member 63 function as protruding parts that protrude upward due to the force received from the input screw 74 (input part).

[0036] The cover 67 opens downward so as to cover from above the case 51, which houses the lower slide member 55, the upper slide member 58, and the protruding member 63. The cover 67 is fixed to the case 51 by engaging with the claws 52 of the case 51. The cover 67 has an opening 68 for the protruding portion, an opening 69 for the screw fastening portion, a threaded hole 70 for the input screw, a threaded hole 71 for the fixing screw, and a locking member restricting portion 72.

[0037] The protruding portion opening 68 is formed in the upper surface 67a and is an opening that allows the protruding member 63 to protrude upward from the case 51. The screw-fastening portion opening 69 is formed in the exterior side surface 67c and is an opening that allows the screw-fastening portion 60 of the upper slide member 58 to protrude from the case 51 to the exterior.

[0038] The input screw threaded hole 70 is a hole with an internal thread for fastening with an input screw 74 inserted from the inside of the room. The fixing screw threaded hole 71 is a hole with an internal thread for fastening with a fixing screw 66 inserted from the inside of the room.

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

[0040] The input screw 74 acts as an input part that receives force from the user. Specifically, the input screw 74 receives a rotational force from the user about an axis that runs in the inward / outward direction from the indoor side to the outdoor side, and moves inward / outward to transmit the force (axial force) to the lower slide member 55, which serves as a conversion part. The input screw 74 has a flat part 75 on the tip 74a side opposite the screw head. The flat part 75 is a part that is cut out symmetrically with respect to the screw axis so as to form a flat surface of a predetermined length in the screw axis direction. By being cut out, the flat part 75 periodically generates areas that do not mesh with the input screw threaded hole 70 during rotation when fastening.

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

[0042] The locking hole 79 is formed on the indoor side surface 78a that is disposed along the indoor side surface 67b of the cover 67, and is composed of a rotation area 82 and a locking area 83 that are disposed continuously in the left-right direction. The rotation area 82 has a dimension that allows the input screw 74 to rotate. The locking area 83 has a dimension that fits with the flat portion 75 of the input screw 74 and restricts the rotation of the input screw 74. In other words, the flat portion 75 of the input screw 74 is designed so that the flat portion 75 is positioned in the locking area 83 when the upper fixing device 50 is applying a tensioning force, which is the timing when it is desired to restrict the rotation of the input screw 74.

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

[0044] The restriction hole 81 is a hole formed in the upper surface 78b (FIG. 7) that is disposed along the upper surface 51a of the case 51, and has a length in the left-right direction that is approximately the same as the length in the left-right direction of the lock hole 79. The lock member restriction portion 72 of the cover 67 is inserted into the restriction hole 81. As a result, the left-right movement range of the lock member 78 is restricted by the lock member restriction portion 72.

[0045] The fall prevention member 90 is used to prevent the frame member 10 from falling toward the room relative to the window 2. Here, Fig. 10 is a perspective view of the fall prevention member 90. Fig. 11 is a diagram showing the mounting device 1 attached to the window 2 using the fall prevention member 90 of Fig. 10, viewed from the left. Fig. 12 is a diagram showing the mounting device 1 attached to the window 2, viewed from the room side.

[0046] The anti-tip member 90 is formed, for example, by bending a single flat metal plate. The anti-tip member 90 has a length approximately equal to the length of the upper frame 11 in the left-right direction, and is disposed so as to straddle the left and right upper fixing devices 50. The anti-tip member 90 has a fixing portion 93 and a gripping portion 94.

[0047] The fixing portion 93 is a flat surface facing in the vertical direction, and has a screw hole 95 for being fastened together with the screw 92 in the screw fastening portion 60. The tipping prevention member 90 is fixed to the frame member 10 via the upper slide member 58 by being screwed at the fixing portion 93, and is integrated therewith.

[0048] The gripping portion 94 is a portion formed by bending downward from the outdoor-side edge of the fixing portion 93, and is a roughly U-shaped portion that opens upward and is made up of a pair of surfaces that face each other in the indoor-outdoor direction along the vertical direction and a surface that connects these surfaces along the indoor-outdoor direction. The gripping portion 94 has a length in the indoor-outdoor direction that is greater than the length of the riser 7 of the sash 3 in the indoor-outdoor direction, and grips the riser 7 from below.

[0049] The gripping portion 94 has a vertical surface that is located on the indoor side and extends downward from the fixed portion 93, and functions as a covering portion 96. As shown in FIG. 12 , the covering portion 96 covers the space between the upper frame 4a of the frame and the upper frame 11 below the fixed portion 93 in the indoor / outdoor direction. The covering portion 96 extends downward to a length that overlaps with the upper frame 11. Furthermore, because the anti-tip member 90 is fixed to the upper slide member 58, the anti-tip member 90 also rises as the upper slide member 58 rises. Therefore, the vertical length of the covering portion 96 is determined so that it always overlaps with the upper frame 11 even after rising, in order to maintain the sealing effect achieved by overlapping with the upper frame 11. This allows the indoor / outdoor sealing to be maintained even if the anti-tip member 90 moves.

[0050] Furthermore, the surface of the gripping portion 94 that is arranged on the outdoor side and extends in the vertical direction and is parallel to the cover portion 96 functions as a support surface 97. As shown in Fig. 11, the support surface 97 comes into surface contact with a supported surface 7a of the rising portion 7 that is the surface of the rising portion 7 that extends in the vertical direction of the sash 3 and faces the outdoor side.

[0051] The gripping portion 94 need only have a shape that corresponds to the shape and dimensions of the rise 7, and is not limited to the example shown in FIG. 10. For example, FIG. 13 is a perspective view of a modified anti-tip member 90. FIG. 14 is a left-side view of the mounting device 1 attached to the window 2 using the anti-tip member 90 of FIG. 13. The anti-tip member 90 of FIG. 13 differs from the anti-tip member 90 of FIG. 10 in that the dimensions of the gripping portion 94 have been changed to match the dimensions of the rise 7.

[0052] Specifically, in Figure 14, if the rise 7 is, for example, less than 21 mm, the vertical length of the gripping portion 94 connected to the fixing portion 93 can be reduced, thereby making it possible to configure and install the anti-tip member 90 in the same manner as in Figures 10 to 12.

[0053] Next, a procedure for attaching the attachment device 1 in this embodiment to the frame 4 (window 2) will be described.

[0054] The mounting device 1 is positioned on the frame bottom frame 4b while abutting against the rising edge 7 of the sash 3, after the height of the lower fixing member 40 is adjusted according to the dimensions of the rising edge 7 of the sash 3 to which it is to be attached. The mounting device 1 is positioned using the fall prevention member 90 for positioning in the indoor / outdoor directions, with the rising edge 7 inserted into the gripping portion 94. The mounting device 1 is also positioned so that the support surface 97 contacts the supported surface 7a of the rising edge 7. Then, according to the height of the frame 4, the inner vertical frame 16 is extended until the contact surface 65 of the upper fixing member 50 contacts the frame top frame 4a, adjusting the height of the vertical frame 13. Once the position of the inner vertical frame 16 is determined, the inner vertical frame 16 is fixed to the outer vertical frame 17 with the tightening screws 18.

[0055] Next, the input screws 74 of the two upper fixing devices 50 are rotated in the tightening direction. At this time, the locking member 78 is slid so that the input screws 74 are positioned in the rotation region 82. When the input screws 74 are tightened, the lower slide member 55 is pushed into the input screws 74 and moves toward the outside of the room, transitioning from the state shown in FIG. 8 to the state shown in FIG. 9. Then, the upper slide surface 59, which contacts the lower slide surface 56, slides up the lower slide surface 56 relatively, resulting in the upper slide member 58 rising. The protruding member 63 also rises in conjunction with the input screws 74, bringing the contact surface 65 into close contact with the upper frame 4a, generating a tension force between the upper and lower frame 4a, 4b, and the mounting device 1. That is, the lower slide member 55, the upper slide member 58, and the protruding member 63 convert the force received from the input screws 74 as an input unit into a force that tensions the mounting device 1 vertically against the frame 4.

[0056] Thereafter, the locking member 78 is slid to the left, and the flat portion 75 fits into the locking region 83, restricting rotation of the input screw 74 in the loosening direction. This makes it possible to prevent the tensioning force from decreasing due to loosening of the input screw 74.

[0057] The mounting device 1 in this embodiment has a higher degree of freedom in terms of the mounting location than conventional mounting devices, such as mounting devices that are fixed to the frame 4 via the rising edge 7 of the sash 3 by the fastening force of screws in the indoor / outdoor directions, or mounting devices that are fixed directly to the frame 4 using screws or the like.

[0058] Furthermore, because the fall prevention member 90 is supported by the rising portion 7 of the sash 3, the mounting device 1 and the air conditioner 5 can be prevented from falling indoors even if the tensioning force is unintentionally reduced. That is, the mounting device 1 is firmly fixed to the frame 4 by the upper fixing member 50, but by using the fall prevention member 90 as an auxiliary, it is possible to further prevent the device from falling and increase safety.

[0059] 15 is an example of a conventional mounting device 101, and is a diagram showing the vicinity of an upper frame 111. FIG. 16 is a diagram illustrating the mounting device 101 of FIG. 15 when it is placed in a frame 4.

[0060] In the conventional mounting device 101, a pair of upper and lower frames 111, 112 have mating portions 113 and clamping screws 114 as fastening members. The mating portions 113 are grooves formed between two rising portions 115 on the exterior sides of the upper and lower frames 111, 112. The mating portions 113 receive and fit with rising portions 7 of the sash 3, for example, rising portions that are vertically (from bottom to top, from top to bottom) arranged on the exterior side of the frame 4. The clamping screws 114 secure the fit between the rising portions 7 and the mating portions 113 with a fastening force. Specifically, the clamping screws 114 have a threaded shaft that extends in the indoor-outdoor direction, and when tightened from the interior side, they clamp and fix the rising portions 7 of the sash 3 together with the rising portions 115 that are arranged on the exterior sides of the upper and lower frames 111, 112.

[0061] Such a mounting device 101 needs to be high enough to be clamped and fastened between the clamping screw 114 and the fitting portion 113 relative to the rising portion 7, so if the rising portion 7 is not high enough, the mounting device 101 could not be mounted. Also, since the mounting device 101 is mounted to the frame 4 via the rising portion 7, the rising portion 7 is subjected to the weight of the mounting device 101 and the air conditioner 5, so the mounting device 101 could not be mounted to a rising portion 7 that does not have enough strength to withstand this load (for example, a sash 3 made of steel or wood).

[0062] Furthermore, if the sash 3 does not have sufficient height or strength for the rise 7, it is possible to attach separately prepared reinforcing metal fittings to the frame 4 or sash 3, and to attach the mounting device 101 via the reinforcing metal fittings instead of the rise 7. However, in cases where there are restrictions on drilling holes in the equipment, such as in rental properties, it is not possible to attach the reinforcing metal fittings, and it is also not possible to install the mounting device 101.

[0063] In contrast, the mounting device 1 in this embodiment is fixed to the frame 4 (window 2) by utilizing the tension (friction) in the vertical direction between the mounting device 1 and the frame 4. Therefore, the mounting device 1 can be attached to any window 2 or sash 3 as long as the frame 4 has dimensions that allow the mounting device 1 to be placed thereon.

[0064] Furthermore, by designing the upper fixing device 50 (lower fixing device 40) to appropriate dimensions, the mounting device 1 of this embodiment can also be mounted on the upper and lower frames 111, 112 of a conventional mounting device 101 as shown in FIGS. 15 and 16 . Therefore, the mounting device 1 of this embodiment can also be realized by attaching the upper fixing device 50 (lower fixing device 40) to a conventional mounting frame. For example, the tightening screws 114 are removed, and the upper fixing device 50 is placed in the space formed between the rising portions 115 on the outdoor side of the upper frame 111, and the upper fixing device 50 is fixed to the rising portion 115 closest to the indoor side with the fixing screws 66. The lower fixing device 40 is also fixed to the lower frame 112. In this way, the mounting frame of the conventional mounting device 101 can be used to form the mounting device 1.

[0065] Although several 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 embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the inventions described in the claims and their equivalents.

[0066] Although the example in which the fall prevention member 90 is attached to the sash 3 having the rising portion 7 has been described, the fall prevention member 90 may also be applied to a sash 3 without the rising portion 7.

[0067] Fig. 17 is a perspective view of a fall prevention member 90 that is applied to a sash 3 that does not have a rising portion 7. Fig. 18 is a view from the left of the mounting device 1 that applies the fall prevention member 90 of Fig. 17 and is attached to a window 2. Fig. 19 is a view from the inside of the room of the mounting device 1 that is attached to the window 2. Fig. 20 is a view from the inside of the room of the mounting device 1 that is attached to the window 2 excluding the fall prevention member 90.

[0068] The tip-prevention member 90 differs from the tip-prevention member 90 in FIG. 10 in that the shape of the support surface 97 is different, but the rest of the structure is almost the same, so the same reference numerals will be used for overlapping components and explanations will be omitted.

[0069] The fall prevention member 90 is formed by bending and cutting a single flat plate material. The fall prevention member 90 has a fixing portion 93, a cover portion 96, and a support surface 97. The support surface 97 is formed in a different shape from the fall prevention member 90 in FIG. 10 to accommodate a sash 3 that does not have a riser 7.

[0070] Here, as shown in Fig. 18, a sash 3 without a rising edge 7 has a connecting member 8 that connects the exterior surface of the frame upper edge 4a to the interior surface of the rail 6 of the sash 3. The connecting member 8 is located on the interior side of the rail 6, and has a surface that faces the exterior along the vertical direction (lengthwise), and is located above the fixing part 93. This surface corresponds to the supported surface 7a of the rising edge 7 of the sash 3 in Fig. 11 that faces the exterior, and functions as the supported surface 8a.

[0071] The support surface 97 is a portion formed by cutting and raising (rising upward by 90 degrees) a certain width near the center in the left-right direction of the flat plate-shaped surface that forms the fixing portion 93. The support surface 97 is approximately on the same plane as the covering portion 96, and the covering portion 96 is bent downward by 90 degrees from the fixing portion 93, while the support surface 97 is bent upward by 90 degrees from the fixing portion 93. The support surface 97 comes into surface contact with the supported surface 8a of the sash 3, as shown in FIG.

[0072] Even in a sash 3 without a raised portion 7, if the sash 3 has a surface facing the exterior, the support surface 97 engages with this surface, effectively preventing the mounting device 1 and air conditioner 5 from tipping over. Furthermore, as shown in FIG. 20 , when the raised portion 7 is absent, the upper fixing device 50 creates a gap S between the upper frame 4a and the upper frame 11, allowing communication between the interior and exterior of the room, resulting in inconvenient use. However, by providing the raised portion 7, the cover portion 96 can cover the gap S below the fixing portion 93, as shown in FIG. 19 . Furthermore, as shown in FIGS. 18 and 19 , a sealing member 98 is provided to seal the gap between the fixing portion 93 and the upper frame 4a (connecting member 8) above the fixing portion 93. The sealing members 98 are disposed on the fixing portion 93, one on each side of the support surface 97. As a result, in the case where there is no rising portion 7, the fall prevention member 90 can have both the function of preventing the sash 3 from falling by engaging with it and the function of covering the unnecessary gap S.

[0073] Furthermore, if the fall prevention member 90 is fixed to the upper frame 11 instead of the upper slide member 58, the tensioning action of the upper fixing device 50 will increase the distance between the upper frame 4a and the upper frame 11. In this case, there is a risk that the sealing performance in the gap S will be reduced. However, by fixing the fall prevention member 90 to the upper slide member 58, the fall prevention member 90 rises together with the upper slide member 58, which improves the adhesion of, for example, the sealing member 98 to the upper frame 4a, and the sealing performance can be maintained.

[0074] Furthermore, while the above description uses an example in which the upper fasteners 50 are disposed at two locations, on the left and right ends of the upper frame 11, one upper fastener 50 may be disposed at the center in the left-right direction, or three upper fasteners 50 may be disposed at the left and right ends and the center. Furthermore, the left-right length of the upper fastener 50 may be set to a length that extends across the entire left-right direction of the upper frame 11. In this case, since the left-right lengths of the lower slide member 55 and the upper slide member 58 are also increased, the input screw 74 and the lock member 78 may be disposed at two locations, such as on the left and right ends. Even in these cases, the anti-tip member 90 is configured in such a way that the fixing portion 93, the covering portion 96, and the support surface 97 function appropriately depending on the presence or absence of the rise 7, the gap S, and the screw fastening portion 60.

[0075] Although the mounting device according to the present invention has been described using an example in which the equipment to be mounted is an air conditioner 5, it can be applied to mounting any equipment or structure to be installed on a window. For example, even if the mounting device and the equipment or structure to be mounted are pre-integrated, this can still be included in the concept of the mounting device according to the present invention. Furthermore, the mounting device may not be a frame-shaped member, but may be a panel-shaped member having an inner panel and an outer panel that supports the equipment. For example, the equipment may be a heat exhaust duct that is connected to an air conditioner placed on the floor and extends to the outside, and the panel-shaped mounting device may be used to attach this heat exhaust duct to a window by passing it through the panel.
