DETAILED DESCRIPTION OF THE INVENTION

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a fastener and an attachment device including the same according to the present invention will be described with reference to the accompanying drawings.

[0011] In the following explanation, "up," "down," "right," "left," "indoor," and "outdoor" follow the definitions in Figures 1 to 13. The vertical direction refers to the up-down direction. The horizontal direction includes the left-right direction and the indoor-outdoor direction (the direction connecting the indoor and outdoor areas).

[0012] 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.

[0013] FIG. 2 is a perspective view of the appearance of the mounting device 1 attached to the frame 4. As shown in FIG.

[0014] FIG. 3 is a perspective view showing the appearance of the mounting device 1 with the air conditioner 5 mounted thereon.

[0015] FIG. 4 is an explanatory diagram of the window 2 and frame 4 to which the air conditioner 5 is attached.

[0016] 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 air conditioner 5) to a frame 4, which is used with the window 2 partially open. The frame 4 is a frame material that surrounds the window 2 and is arranged to separate (separate) the window 2 from the interior wall. The frame 4 is arranged on the indoor side of the window 2 and the sash 3 of the window 2, 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 fixed width in the indoor / outdoor direction.

[0017] 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 cover member 90.

[0018] 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).

[0019] The upper frame 11 is disposed above the frame member 10 in the left-right direction parallel to 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. The upper frame 11 has a pair of rising portions 11b on the upper surface 11a that face each other in the indoor / outdoor direction. The rising portion 11b on the outdoor side has positioning holes 11c at positions corresponding to protrusions 51f of the lower case 51, which will be described later, for positioning the upper fixing device 50 when disposing it on the upper surface 11a (FIGS. 8 and 9).

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] The lower fixing device 40 has an adjustment portion 41 , a non-slip portion 42 , and a packing 43 .

[0026] 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.

[0027] 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.

[0028] 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 3a of the sash 3 closest to the room, hanging down into the groove formed between the rising edges 3a.

[0029] 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 3a, 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 3a, allowing the gasket 43 to be positioned to cover the rise 3a, preventing rainwater from entering the interior of the room. On the other hand, if the sash 3 does not have a rise 3a, there is no need to raise the position of the sill 12, so only the upper block 41a can be used.

[0030] The upper fixing members 50 are detachably arranged at two locations on the left and right ends of the upper surface 11a of the upper frame 11. The upper fixing members 50 generate a tension force on the frame member 10 to attach the frame member 10 (second member) to the pair of upper and lower frame members 4a, 4b (first members) with a tension force in the up-down direction (first direction, vertical direction). In this way, the mounting device 1 fixes the frame member 10, which holds the air conditioner 5, to the frame 4. Specifically, the upper fixing members 50 further extend vertically when the pair of vertical frames 13 extend vertically and the upper end of the mounting device 1, i.e., the upper surface (contact surface 65) of the upper fixing member 50 arranged at the top of the mounting device 1, contacts the upper frame member 4a (the upper upper and lower frame members of the frame), thereby tensioning the frame member 10 in the vertical direction.

[0031] Here, Fig. 6 is a perspective view of the upper fixing device 50 as seen from the indoor side. Fig. 7 is a perspective view of the upper fixing device 50 as seen from the outdoor side with the upper case 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 no tension force is applied. 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 a tension force is applied. Fig. 10 is a vertical cross-section for particularly explaining the fitting structure of Fig. 6, where (a) is a view showing a state in which the input screw 74 is in the rotation region 82, and (b) is a view showing a state in which the input screw 74 is in the lock region 83.

[0032] The upper fixing device 50 includes cases 51 and 67 , a lower slide member 55 , an upper slide member 58 , a protruding member 63 , an input screw 74 , and a locking member 78 .

[0033] The cases 51 and 67 are composed of a lower case 51 and an upper case 67, which house the lower slide member 55, the upper slide member 58, and the protruding member 63 (conversion unit). The lower case 51 has 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 exterior sides as shown in FIG. 7. The lower case 51 houses the lower slide member 55 and the upper slide member 58 in its internal space. The lower case 51 has claws 52 on its left and right side surfaces 51d that mate with the upper case 67. The lower case 51 also has input screw holes 53 and fixing screw holes 54 on its interior side surface 51b. The input screw holes 53 allow input screws 74 inserted from the interior side to pass through into the internal space. The fixing screw holes 54 are holes that receive fixing screws 66 for fixing the upper fixing device 50 to the upper frame 11. The lower case 51 has a protrusion 51f on its exterior side surface 51e (FIG. 7) that fits into a positioning hole 11c in the rising portion 11b of the upper frame 11. When placing the upper fixing device 50 on the upper frame 11, the protrusion 51f is positioned so that it fits into the positioning hole 11c, which makes positioning easier and also serves as a temporary fixation before the upper fixing device 50 is screwed to the upper frame 11. In addition, as shown in FIG. 10, the lower case 51 has a support surface 51g on its upper surface 51a that supports the sliding locking member 78 while making surface contact with the upper surface 78b of the locking member 78.

[0034] The upper case 67 is open downward so as to cover from above the lower case 51, which houses the lower slide member 55, the upper slide member 58, and the protruding member 63. In particular, the upper case 67 covers the lower case 51 so as to cover the upper surface 78b of the locking member 78 that is disposed on the support surface 51g. The upper case 67 is fixed to the lower case 51 by engaging with the claw portions 52 of the lower case 51. The upper case 67 has a protruding portion opening 68, a screw fastening portion opening 69, an input screw threaded hole 70, a fixing screw threaded hole 71, a locking member restricting portion 72, and a lock hole 73.

[0035] 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 lower 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 lower case 51 to the exterior side.

[0036] 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.

[0037] The locking member restricting portion 72 is a piece-like portion cut out from the upper surface 67a and bent downward at a substantially right angle. The locking member restricting portion 72 is inserted into the restricting hole 81 of the corresponding locking member 78, thereby restricting the left-right movement range of the sliding locking member 78 on the lower case 51. The locking holes 73 are recessed holes located in two places to the right of the locking member restricting portion 72. The locking holes 73 are located at positions that engage with the locking protrusions 85 when the input screw 74 is in the rotation region 82 and when the input screw 74 is in the locking region 83.

[0038] The lower slide member 55 has a triangular prism shape that appears trapezoidal in cross section in Figures 8 and 9 and is made of, for example, resin. The lower slide member 55 is disposed on the bottom surface 51c of the lower case 51. The lower slide member 55 has an indoor / outdoor length that is shorter than the indoor / outdoor length of the interior space of the lower case 51 and is movable indoors and outdoors. 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 inclined relative to the horizontal direction so that the outdoor side is positioned downward. The screw receiving portion 57 is disposed on the indoor side surface 55a and receives the tip 74a of the input screw 74. The screw receiving portion 57 is preferably disposed at the vertical center of the lower slide surface 56 to prevent the force received from the input screw 74 from being dispersed in directions other than the outdoor direction.

[0039] 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 that is inclined relative to the horizontal direction so that the outdoor side is located downward, and is a surface that is 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 cover member 90. The connecting portion 61 connects and holds the protruding member 63 by a fitting structure.

[0040] 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 a surface facing upward and approximately parallel to the upper frame 4a. It moves upward as the upper slide member 58 rises, comes into close contact with the upper frame 4a, and generates a tension force between the contact surface 65 and the upper frame 4a. The contact surface 65 generates a horizontal frictional 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 the required frictional force against the frame 4 and has cushioning properties that prevent it from damaging the upper frame 4a when it comes into contact with the upper frame 4a. The contact surface 65 may be made of various materials, such as rubber, felt, silicone, sponge, urethane, etc. Only the contact surface 65 may be made of these materials, or the entire protruding member 63 may be made of these materials.

[0041] The input screw 74 functions as an input unit that receives force from the user. Specifically, the input screw 74 moves in the indoor / outdoor direction by receiving a rotational force from the user about an axis along the indoor / outdoor direction, which is the direction connecting the indoor and outdoor sides. In particular, the input screw 74 receives force in the outdoor direction (second direction) and transmits the force to the lower slide member 55, which serves as a conversion unit. The input screw 74 has a flat portion 75 on the tip 74a side opposite the screw head. The flat portion 75 is formed by cutting out a predetermined length in the threaded outer surface in the threaded axial direction to form a flat surface. The flat portion 75 is formed, for example, by cutting out symmetrically with respect to the thread axis. By cutting out the flat portion 75, periodic regions that do not engage with the input screw threaded hole 70 during rotation during fastening are periodically generated. Note that the flat portion 75 may be at least one flat surface formed in the circumferential direction as long as it engages with the locking region 83 of the locking member 78 and restricts rotation of the input screw 74.

[0042] The locking member 78 can lock the rotation of the input screw 74 by sliding (moving) in the left-right direction on the lower case 51. The locking member 78 is a substantially L-shaped member when viewed in the left-right direction, and is made of, for example, a metal having the required strength, and is composed of an indoor side surface 78a (first surface) and an upper surface 78b (second surface) perpendicular to the indoor side surface 78a. The locking member 78 has a through-hole 79, a knob 80, a restricting hole 81, a leaf spring portion 84, and a locking protrusion 85.

[0043] The through-hole 79 is a hole through which the input screw 74 passes. The through-hole 79 is formed in the interior side surface 78a, which is disposed along the interior side surface 67b of the upper case 67, and is composed of a rotation area 82 and a locking area 83, which 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 when rotation of the input screw 74 is to be restricted. In addition, the locking member 78 can slide left-right relative to the input screw 74 to switch the position of the input screw 74 between the rotation area 82 and the locking area 83.

[0044] The knob 80 is used when the user moves the lock member 78 left and right on the lower case 51.

[0045] 7, the restriction hole 81 is a hole formed in the upper surface 78b that is disposed along the upper surface 51a of the lower case 51, and has a length in the left-right direction that is approximately the same as the length of the through-hole 79. The locking member restriction portion 72 of the upper case 67 is inserted into the restriction hole 81. As a result, the left-right movement range of the locking member 78 is restricted by the locking member restriction portion 72.

[0046] As shown in FIG. 10 , the leaf spring 84 is disposed on the upper surface 78b and has a base located on the left and a tip located on the right in the left-right direction (sliding direction). The leaf spring 84 changes its arm length as a leaf spring depending on the amount of contact with the support surface 51g of the lower case 51. That is, the leaf spring 84 is disposed on the left so that its base is closer to the support surface 51g, so that the arm length is shorter when the input screw 74 is in the locking region 83 than when it is in the rotation region 82. The locking protrusion 85 is a hemispherical protrusion located on the upper surface of the leaf spring 84, closer to the tip than the base. The locking protrusion 85 and the locking hole 73 of the upper case 67 function as an engagement structure that engages with each other when the input screw 74 slides into the locking region 83 and disengages when the input screw 74 slides toward the rotation region 82.

[0047] The covering member 90 is a member made of, for example, metal, and 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 left and right direction of the upper frame 11 and is held in place by being screwed into two screw fastening portions 60 of the upper fixing device 50. If the sash 3 has a raised portion 3a, the covering member 90 may have a gripping portion 91 that grips the raised portion 3a. The gripping portion 91 has a shape corresponding to the shape and dimensions of the raised portion 3a, and in addition to fixing the mounting device 1 and the air conditioner 5 by the tensioning force of the upper fixing device 50, it can also function to prevent the mounting device 1 and the air conditioner 5 from tipping over.

[0048] Next, a procedure for attaching the attachment device 1 in this embodiment to the frame 4 (window 2) will be described.

[0049] The mounting device 1 is positioned on the lower frame 4b of the frame, with the height of the lower fixing member 40 adjusted according to the dimensions of the rising edge 3a of the sash 3 to which it is to be attached, and the lower fixing member 40 abuts against the rising edge 3a of the sash 3. 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 upper frame 4a of the frame, and the height of the vertical frame 13 is adjusted. Once the position of the inner vertical frame 16 has been determined, the inner vertical frame 16 is fixed to the outer vertical frame 17 with the tightening screws 18.

[0050] 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. In addition, the locking protrusion 85 is engaged with the right locking hole 73. When the input screws 74 are tightened, the lower sliding member 55 serving as a conversion member 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. At this time, the lower sliding member 55 receives force from the input screws 74 at the center of the lower sliding surface 56 in the vertical direction, thereby preventing the lower sliding member 55 from tilting and moving in a direction other than the outside of the room.

[0051] As a result, the upper slide surface 59, which contacts the lower slide surface 56, slides up the lower slide surface 56 relatively, causing the upper slide member 58 to rise. Furthermore, the protruding member 63 also protrudes upward in conjunction with the lower slide surface 59, causing the contact surface 65 to come into close contact with the upper frame 4a of the frame, and a tension force is generated between the upper and lower frame 4a, 4b of the frame and the mounting device 1. In other words, the lower slide member 55, the upper slide member 58, and the protruding member 63 function as a conversion unit that converts the axial force of the input screw 74, which serves as an input unit, into a force that tensions the mounting device 1 vertically against the frame 4.

[0052] When the lower slide member 55 is pushed outward, the outdoor side surface 67c of the upper case 67 receives a force in a direction that opens it toward the outside of the room. The indoor side surface 67b also receives a force from the input screw 74 in a direction that opens it toward the room. However, the outdoor side surface 67c and the indoor side surface 67b of the upper case 67 are arranged to overlap the two rising portions 11b of the upper frame 11 in the vertical direction, and the upper fixing device 50 is positioned on the upper surface 11a so that the outdoor side surface 67c and the indoor side surface 67b are sandwiched between the two rising portions 11b. This prevents deformation of the outdoor side surface 67c and the indoor side surface 67b of the upper case 67, efficiently transmitting the axial force of the input screw 74 in the outdoor direction to the lower slide member 55, and further raising the upper slide member 58.

[0053] After the tension force acts on the frame 4, the input screw 74 is rotated until the flat portion 75 faces up or down to lock the rotation of the input screw 74. The locking member 78 is slid leftward relative to the input screw 74. At this time, the locking protrusion 85 of the locking member 78 is engaged with the right locking hole 73 of the upper case 87. However, as the locking member 78 is slid leftward, the leaf spring portion 84 bends downward, releasing the engagement between the locking protrusion 85 and the locking hole 73. The user can recognize that the sliding operation is effective by the clicking sensation. As the locking member 78 slides, the flat portion 75 of the input screw 74 engages with the locking region 83, restricting the rotation of the input screw 74 in the loosening direction. When the locking member 78 is slid leftward to the designed sliding completion position, the locking protrusion 85 engages with the left locking hole 73. The user can recognize that the locking member 78 has been slid to the locking region 83 by the clicking sensation that occurs when the locking protrusion 85 and the locking hole 73 fit together. This prevents the tensioning force from decreasing due to loosening of the input screw 74. Furthermore, because the amount of contact between the leaf spring 84 and the support surface 51g increases, the arm length of the leaf spring 84 becomes shorter than when the input screw 74 is located in the rotation region 82, making the leaf spring 84 less likely to bend. This prevents the locking protrusion 85 and the locking hole 73 from unintentionally coming loose, causing the locking member 78 to slide.

[0054] 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 3a of the sash 3 by the fastening force of screws in the indoor / outdoor direction, or mounting devices that are fixed directly to the frame 4 using screws or the like.

[0055] 11 is an example of a conventional mounting device 101, and is a diagram showing the vicinity of an upper frame 111. FIG. 12 is a diagram illustrating the mounting device 101 of FIG. 11 when it is placed in a frame 4.

[0056] In the conventional mounting device 101, a pair of upper and lower frames 111, 112 have a mating portion 113 and a clamping screw 114 as a fastening member. The mating portion 113 is a groove formed between two rising portions 115 on the exterior sides of the upper and lower frames 111, 112. The mating portion 113 receives and fits with the rising portion 3a of the sash 3, for example, a rising portion that is vertically (from bottom to top, from top to bottom) arranged on the exterior side of the frame 4. The clamping screw 114 secures the fit between the rising portion 3a and the mating portion 113 by a fastening force (axial force). Specifically, the clamping screw 114 has a screw shaft that extends in the indoor / outdoor direction. When tightened from the interior side of the room, the clamping screw 114 clamps and secures the rising portion 3a of the sash 3 together with the rising portion 115 that is arranged on the exterior side of the upper and lower frames 111, 112.

[0057] Such a mounting device 101 needs to be tall enough to be clamped and fastened between the clamping screw 114 and the fitting portion 113 relative to the rising portion 3a, so if the rising portion 3a is not tall 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 3a, the rising portion 3a 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 3a that does not have enough strength to withstand this load (for example, a sash 3 made of steel or wood).

[0058] Furthermore, if the sash 3 does not have sufficient height or strength for the rising portion 3a, the mounting device 101 can be mounted via the reinforcing metal fittings instead of the rising portion 3a by attaching separately prepared reinforcing metal fittings to the frame 4 or the sash 3. However, in cases where there are restrictions on drilling holes in the equipment, such as in rental properties, it is not possible to mount the reinforcing metal fittings, and therefore the mounting device 101 cannot be mounted.

[0059] In contrast, the mounting device 1 in this embodiment is fixed to the frame 4 (window 2) by utilizing the tensioning force (frictional force) in the vertical direction between the upper fixing device 50 and the frame 4. Therefore, the mounting device 1 can be attached to any window 2 or sash 3 as long as the tensioning force of the upper fixing device 50 can be applied to the mounting destination and the frame 4 has dimensions that allow the mounting device 1 to be placed therein.

[0060] In particular, the mounting device 1 in this embodiment can easily generate tensioning force by utilizing the input screw 74, and can suitably prevent a decrease in tensioning force due to loosening of the input screw 74 by utilizing the input screw 74 having the locking member 78 and the flat portion 75 for restricting rotation by the locking member 78. Therefore, the mounting device 1 is easy to mount and can also maintain mounting strength after mounting.

[0061] Furthermore, by designing the upper fixing member 50 (lower fixing member 40) to appropriate dimensions, the mounting device 1 of this embodiment can also be mounted on the upper and lower frames 111 and 112 of a conventional mounting device 101, as shown in FIGS. 11 and 12 . Therefore, the mounting device 1 of this embodiment can also be realized by attaching the upper fixing member 50 (lower fixing member 40) to a conventional mounting frame. For example, the fastening screw 114 is removed, and the upper fixing member 50 is placed in the space formed between the two rising portions 115 on the indoor side of the upper frame 111. At this time, the threaded hole 115a of the fastening screw 114 of the rising portion 115 on the indoor side can be used as a threaded hole for fixing the upper fixing member 50 with the fixing screw 66. Furthermore, the threaded hole 115b of the fastening screw 114 of the rising portion 115 on the outdoor side can be used as a positioning hole 11c that fits with the protrusion 51f. The lower fixing member 40 is also fixed to the lower frame 112. This allows the mounting frame of the conventional mounting device 101 to be used to form the mounting device 1.

[0062] 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.

[0063] For example, although an example has been described in which the upper fixing device 50 is disposed at two locations, one on the left and right ends of the upper frame 11, one upper fixing device 50 may be disposed at the center in the left-right direction, or three upper fixing devices 50 may be disposed at the left and right ends and the center. Also, the left-right length of the upper fixing device 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, one on the left and right ends.

[0064] Furthermore, although an example has been described in which the fastener that generates tension force is the upper fastener 50, as shown in Fig. 13, a fastener 201 having a configuration similar to that of the upper fastener 50 may be disposed between the lower frame 12 and the lower frame 4b of the frame as a fastener to fix the mounting device 1 with a similar tension force. Furthermore, the fastener is not limited to a vertical tension force, and may be disposed so as to generate a horizontal tension force.

[0065] Although the above description uses an example in which upper fixing device 50 has lock hole 73 arranged in upper case 67 and lock protrusion 85 arranged in the locking member as an example of a fitting structure that is provided in the locking member and the case and that engages when the input screw is slid into the lock region and releases the fitting when the input screw is slid into the rotation region, it is also possible to provide a leaf spring corresponding to leaf spring portion 84 in lower case 51 and to provide a recess corresponding to lock hole 73, and to provide a protrusion that corresponds to lock protrusion 85 and corresponds to the recess in lower case 51 on the surface of upper surface 78b of locking member 78 that faces lower case 51, and to form a fitting structure using these recesses and protrusions. Furthermore, the fitting structure may not only be one that engages when the input screw is in the rotation region and the lock region, but also one that engages only when it is in the lock region.

[0066] 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.
