Is increasing. As shown in FIG. 6, the mounting device using the auxiliary frame disclosed in the above publication is hung from the ceiling in a frame structure 102 that is fitted and mounted to a mounting frame 101 that is provided on the ceiling and has an opening on the ceiling surface. In addition, a gate-shaped suspension frame 105 provided with a mounting plate 104 for mounting to the anchor bolt 103 is projected so as to straddle the frame structure 102. The mounting plate 104 is provided with a bolt insertion hole in which a vibration-proof rubber 106 is mounted, and the vibration-proof rubber 106 is sandwiched by a nut 107 screwed to the anchor bolt 103 via a washer.

In this mounting device, as shown in FIG. 7, a suspension frame 105 which is integral with the frame structure 102 is suspended and supported by the mounting plate 104 on the anchor bolt 103 via a vibration-proof rubber 106, and a ventilation fan is installed in the frame structure 102. The ventilation fan main body 108 is fixed to the mounting frame 101 that houses the main body 108 and is provided on the ceiling together with the frame structure 102 and forms an opening on the ceiling surface. That is, the ventilation fan main body 108 has the frame structure 102.
The ventilation fan main body 1 can be attached to the attachment frame 101 via the
08 is set in an appropriate mounting position only by fitting and fixing it in the frame structure 102, and the mounting operation of the ventilation fan main body 108 is simplified.

In the above-mentioned mounting device, the suspension frame 105 has a gate shape that straddles the frame structure 102, and the mounting plate 104 provided in the center of the suspension frame 105 suspends and supports the anchor bolt 103, so that the operation from the opening of the ceiling surface is easy. If the length of the anchor bolt 103 is not specified, it may hit the ventilation fan main body 108, and it may not be applicable when the height of the space above the ceiling is low. Therefore, FIG.
In some cases, the suspension frame 105 is not provided in a gate shape but is divided into right and left parts, and a mounting portion for the anchor bolt 103 is formed outside the frame structure 102 as shown in FIG. As a result, the length of the anchor bolt 103 does not have to be specified, and it can be applied even when the height of the space above the ceiling is low.

However, in any of the above-mentioned mounting devices, the frame structure 102 and the suspension frame 105 are connected to each other, and since the suspension frame 105 largely projects from the frame structure 102, the packaging volume becomes large, Since it is bulky, the cost of storage and transportation is high. Further, as shown in FIG. 9, the ventilation fan main body 108 includes various models such as one capable of ventilating a plurality of rooms by connecting the duct 109 and one capable of changing the connecting direction of the duct 109. However, in the above-described mounting device, the suspension frame 105 becomes an obstacle, and the suspension frame 10
Connection port 1 on the ventilation fan main body 108 side provided on the surface with 5
Since the duct 109 cannot be connected to 10, there is a problem that it cannot be applied to the mounting device of such a model.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an entire ventilation fan mounting device showing an embodiment of the present invention. This ventilation fan mounting device
As shown in FIGS. 1 and 5, a sheet metal frame structure 3 that is fitted and attached to a mounting frame 2 that is provided on the ceiling and forms an opening on the ceiling surface 1, and is hung from the ceiling as shown in FIG. It consists of a hanging bracket 5 for attaching to the anchor bolt 4,
The hanging structure 5 suspends and supports the frame structure 3 on the anchor bolts 4, the ventilation fan main body 6 is housed in the frame structure 3, and the ventilation fan main body 6 is fixed to the mounting frame 2 together with the frame structure 3.

The frame structure 3 is constructed as a rectangular rectangular frame in this example according to the ventilation fan main body 6, and a mounting flange 7 protruding outward is bent at the lower end thereof. The mounting flange 7 has a mounting hole 8 for tightening a screw to the mounting frame 2.
And a connection port attachment hole 9 so that a duct connection port (not shown) can be attached. On the opposing side surfaces of the rectangular tube portion of the frame structure 3, connecting portions for connecting the hanging metal fittings 5 are provided at the center portion in the width direction and the end portion in the width direction near one side, respectively. As shown in FIG. 1, one side and the other side of the connecting portions provided at the end portions in the width direction are diagonally configured, and the central connecting portion is configured to face each other. .

The connecting portion is a square rectangular hole as a locking hole 10 formed in the lower portion of the side surface of the frame structure 3, and this locking hole 10
A square slit-shaped square hole serving as a fixing hole 11 formed immediately above and adjacent to the locking hole 10 is configured as a basic connecting structure. In the illustrated structure, in order to improve the stability at the time of connection, two basic connection structures as described above are provided side by side to form a connection portion.

On the other hand, the hanging metal fitting 5 is constructed as an L-shaped metal fitting which is formed by bending one end side of a strip-shaped metal plate as a mounting portion 12 at a right angle, and a vibration-proof rubber 13 into which the anchor bolt 4 is inserted. The mounted bolt insertion hole 14 is formed vertically (see FIG. 2). A mounting surface 15 is formed on the end portion side opposite to the mounting portion 12. A locking claw 16 is cut and raised on the surface of the mounting surface 15 on the mounting portion 12 side. The locking claw 16 is formed as an upward hook that is elastically deformable in a form like a quarter note rest, and the gap between the locking claw 16 and the mounting surface 15 is usually smaller than the wall thickness of the frame structure 3 (Fig. 2). The two locking claws 16 are also formed side by side in correspondence with the configuration on the frame structure 3 side. The hanging fittings 5 are provided on the left and right sides (may be front and back) one by one, but the left and right sides have the same configuration. Each locking claw 1
The width of 6 is configured to be slightly smaller than the width dimension of the locking hole 10 and the fixing hole 11, and the protrusion 17 on the inner side that is close to the free end, which is warped on the outside, can enter the fixing hole 11. (See Figure 3). That is, the distance between the lower end on the inner side of the locking claw 16 and the protrusion 17 is substantially equal to the dimension between the upper hole edge of the locking hole 10 and the fixed hole 11.

Further, as shown in FIG. 2, the dimension A from the upper surface of the mounting flange 7 of the frame structure 3 to the upper hole edge of the locking hole 10
Therefore, the dimension B from the lower end of the mounting surface 15 of the hanging fitting 5 to the free end of the locking claw 16 is set to be slightly longer. Each hanging metal fitting 5 can be connected as shown in FIGS. 4 and 5 by hooking it from the inside to the connecting portion of the frame structure 3 by using the locking claw 16 with the mounting portion 12 facing outward.
In a state where the mounting surface 15 of the hanging metal fitting 5 is joined and connected to the connecting portion of the frame structure 3, a lower positioning protrusion 18 that hits the lower end of the mounting surface 15 from below and two upper and lower parts that hit both side ends of the mounting surface 15 respectively. A total of four side positioning projections 19 are provided as positioning structures as shown in FIG.

In the ventilation fan mounting device having the above structure, the frame structure 3 and the hanging fitting 5 can be handled in a separated state, and can be packaged in this state. The packaging in this disassembled form is sufficient because the hanging metal fitting 5 can be housed in the frame structure 3 if a packaging container having a volume capable of housing the frame structure 3 is prepared. In this packaging form, the frame structure 3 and the hanging metal fittings 5 are provided.
The packaging volume is significantly smaller than the combined packaging volume, and the cost for storage and transportation can be greatly reduced.

Assembling the ventilation fan mounting device, in which the frame structure 3 and the two suspending members 5 are separated, in a usable state can be performed with almost one touch. That is, the mounting surface 15 of the hanging metal fitting 5 faces the frame structure 3 side, and the mounting portion 12 is attached to the frame structure 3 side.
The locking claws 16 so as to face the outside of the
The hanging fitting 5 may be pulled up by hanging it from the inside of the frame. While the locking claw 16 is elastically deformed, an elastic force acts on the connecting portion of the frame structure 3 and is stopped in a sandwiched state, and the lower end of the mounting surface 15 makes a noise over the lower positioning protrusion 18 and the mounting surface 15 The lower positioning protrusion 18 contacts the lower end.
As a result, the downward displacement of the hanging fitting 5 is restricted, and at the same time, the protrusion 17 on the free end side of the locking claw 16 is locked by the locking hole 1.
It is fitted into the fixing hole 11 immediately above 0 by elastic return, the mounting surface 15 is joined to the inner side surface of the frame structure 3 in a pressure contact state, and the frame structure 3 and the hanging fitting 5 are firmly connected. The mounting surface 15 of the hanging metal fitting 5 in the connected state is constrained by the side positioning protrusions 19 at the upper and lower sides of both sides, and even if there is deviation to the left or right,
A stable and reliable connection state with no vertical deviation or wobbling. If the connecting operation of the hanging metal fitting 5 is properly performed, a noise is generated when the lower end of the mounting surface 15 gets over the lower positioning protrusion 18, so that the connecting operation can be optimized by using this sound as a guide.

Since the hanging metal fittings 5 are wide and the locking claws 16 are also wide, the connection of the hanging metal fittings 5 can be put to practical use only by designing a relatively precise engagement relationship with the locking holes 10. Lateral stability of is obtained. Therefore, it is not always necessary to provide the side part positioning protrusions 19. Further, although the description has been given that the connecting operation of the hanging metal fittings 5 is performed from the inner side surface side of the frame structure 3, in this embodiment, the locking claws 16 are actually provided only from the inner side surface side due to the setting of the dimensions A and B. It cannot be inserted into the locking hole 10. Therefore, it is possible to prevent the erroneous connection mode in which the hanging fitting 5 is connected from the outer side surface.

In this embodiment, the connecting portions of the frame structure 3 are formed by arranging two basic connecting structures side by side, and in accordance therewith, the hanging claws 16 are also provided with two locking claws 16 side by side. However, even one by one can fulfill almost the same function as in the above embodiment. Further, although the fixed hole 11 provides a stable and secure connection, the locking hole 10 and the locking claw 16 are provided.
With the basic configuration of
It can perform basic functions such as ease of assembly.

Regarding the above-mentioned connection of the hanging fitting 5,
This is a case where a duct is connected to the opening on the ceiling surface 1 side of the ventilation fan main body 6 and the back surface or front surface of the ventilation fan main body 6 to perform ventilation.
That is, in such a case, even if the hanging metal fitting 5 is connected to each connecting portion in the central portion of the frame structure 3, the hanging metal fitting 5 does not hinder duct piping and connection. However, as mentioned in the description of the conventional technique, the ventilation fan body 10 shown in FIG.
When it is necessary to change the connecting direction of the duct 109 by connecting the duct 109 as shown in 8, or when it is necessary to change the connecting direction of the duct 109, connect the hanging metal fitting 5 to the center of the ventilation fan main body 108. The duct fitting or connection to the surface corresponding to the surface cannot be carried out because the hanging fitting 5 interferes.
In such a case, the hanging metal fittings 5 are connected using the connecting portions from the diagonal ends of the frame structure 3. As a result, the duct piping and the connection to the surface where the hanging metal fitting 5 is located can be performed without any trouble, and the ventilation fan mounting device has versatility.

The mounting of the ventilation fan mounting device itself on the ceiling is the same as the conventional one. That is, as shown in FIG. 5, the anchor bolt 4 is passed through the anti-vibration rubber 13 through the bolt insertion hole 14 provided in the mounting portion 12 of each suspension fitting 5 connected to the frame structure 3 and fixed by the nut 20. Suspend and support the whole,
The ventilation fan main body 6 is housed in the frame structure 3, and together with the mounting flange 7 of the frame structure 3, the flange of the ventilation fan main body 6 is fixed to the mounting frame 2 which is provided on the ceiling and forms an opening in the ceiling surface 1. At this time, since the mounting portion 12 of the hanging metal fitting 5 is outside the projection plane of the frame structure 3, the anchor bolt 4 does not interfere with the ventilation fan main body 6 even if the length of the anchor bolt 4 is not specified, and It can be applied even when the height of the space above the ceiling is low.
