Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shirt shirt attaching device that is improved so as to facilitate attachment and detachment of the shirt shirt.

For example, in a ventilation fan, the shutters that open and close the opening facing the outdoors of the outer frame, the so-called outdoor opening, have conventionally been installed in multiple pieces on a long mounting plate separate from the shaft shutter connection body, etc. By inserting this mounting plate etc. into the outer frame, and then fixing the mounting plate to the outer frame with screws passed from the outside, the outer frame can be rotated for opening and closing through the mounting plate. installed as possible.

However, this product has the disadvantage that, first of all, it requires a long and large separate part called the mounting plate, which is cumbersome to handle, and the product price is also relatively high.

Moreover, when passing a screw through, it is difficult to match the hole in the mounting plate with the hole in the outer frame, and therefore, even though the screw cannot be successfully passed through, the progress of the work is slow.

On the other hand, as a different method from the above, the shaft is inserted into the support shaft while being bent from the outside of the outer frame to the inside, and while releasing the deflection, the hole in the side part of the shirt is inserted into the support shaft. Some shirts are fitted onto a shaft so that the shirt shirt is attached to an outer frame so as to be rotatable for opening and closing.

However, even with this product, compared to the above, it is possible to omit a large separate part called the mounting plate, which is often difficult to work with, and in particular, it is necessary to flex the shirt cover one by one before it can be installed. This has the drawback that the work required to install it is very troublesome and extremely difficult, and once it is installed, it is difficult to even bend the shirt top, so it also has the drawback that it is not easy to remove it. was.

Furthermore, in any of the above conventional structures, the shirt starters are inseparably connected to the respective shirt starter connectors by caulking rivets or the like, so when removing the shirt starters, the shirt starter connectors must also be removed from the outer frame at the same time. However, when it comes to removing the shirt tie connector, the work is obstructed from the outside by the outer frame or the shirt tie.
The disadvantage is that you have to remove the ventilation blades, motors, etc. one by one, even if it is a hassle, to perform service from the inside.Also, even if you take such pains to remove the shirt starter, the shirt starter can be separated by multiple sheets due to the shirt starter connection as described above. Since they remain connected, they have the disadvantage that they cannot be cleaned one by one even when cleaning to remove oil stains and the like after removal.

This invention was made in view of the above-mentioned circumstances,
Therefore, the object is to provide a shirt shirt attaching device that does not require a large separate part such as a mounting plate and can easily and quickly attach and detach the shirt shirt one by one as desired.

An embodiment in which the present invention is applied to a ventilation fan shirt stopper mounting device will be described below with reference to FIGS. 1 to 3.

First, in Fig. 1, 1 is an outer frame that is a shaft support, 2 is a motor mounting leg installed vertically inside the outer frame 1, and a motor 3 is attached to this. 4 is installed.

Incidentally, reference numeral 5 denotes a decorative frame detachably attached to an opening facing the interior of the outer frame 1, that is, an opening on the indoor side so as to surround the ventilation blades 4.

On the other hand, 6 is placed on the outdoor side opening of the outer frame 1, for example, three pieces each.
This shirt shirt is arranged in three tiers, middle and lower, and accordingly, three shaft pins 7 are installed in the outdoor opening of the outer frame 1 on the right side as shown in Fig. 2. It is divided into three stages, each protruding from the outside to the inside.

On the other hand, reference numeral 8 denotes a connector connector, so-called connector lever, which is provided vertically along the left side of the outdoor side opening of the outer frame 1. There are three vertically long holes 10 formed in the upper part and the lower part of the outer frame 1, respectively. It is hung on a piece 11 and held so that it does not fall.

Reference numeral 12 is also provided on the left side of the outdoor opening of the outer frame 1 for the number of shirt shirts 6, that is, in this embodiment, three shirts, top, middle, and
The front end portions of shirt flap attachment pieces arranged in three lower stages are vertically movably connected to the connecting flapper 8 by caulking rivets 13 passed through the elongated holes 10 of the connecting flapper 8, And 1 rivet in each middle part
It is pivotally connected to the outer frame 1 by caulking 4 so as to be movable up and down, and has a bent part 12a facing the rear of the outer frame 1 at the rear end. screw hole 15,
In addition, a horizontally elongated hole 16 is formed in each lower part.

The shirt shutter 6 has a hole 17 corresponding to the shaft pin 7 in the upper part of the right side plate part 6a, and a hole 17 corresponding to the screw hole 15 of the shirt shutter mounting piece 12 in the upper end of the left side. In common with the screw hole 15, there is formed a hole 19 which also corresponds to a screw 18 which is a fitting, and a cut and raised piece 20 which corresponds to the elongated hole 16 of the mounting piece 12.

Now, in order to install the shirt flap 6 based on the above, first, advance each shirt flap 6 from the outside (rear), fit the hole 17 of the right side plate part 6a into one of the shaft pins 7, and then Then, fit the cut and raised piece 20 on the left side into the elongated hole 16 of the shirt flap attachment piece 12 corresponding to one of the shaft pins 7, and insert the left side part into the bent part 12a of the shirt flap attachment piece 12.
Align the hole 19 with the screw hole 15.

Therefore, next, advance the screw 18 from the rear to the hole 1.
9 into the screw hole 15 and tighten strongly.

In this way, one piece of the shirt flap 6 can be attached directly to the outer frame 1 on one side and indirectly to the outer frame 1 via the shirt flap attachment piece 12 on the other side. The same operation as above is carried out for the two plates, and with this, all of the shirt starters 6 can be advanced without requiring large separate parts such as conventional mounting plates, and without bending in any way, and can be positioned effectively. It can be easily and quickly installed, and the state after installation is shown in Fig. 3.

Incidentally, 21 in FIG. 3 is a cushion attached to the shirt flap 6 or the outer frame 1 as appropriate, and is designed to soften the collision of the shirt flap 6 when it is closed, which will be described later, and to prevent the generation of so-called impact noise. There is.

Also, although it is not clear in FIG. 3, as is clear in FIG. 1, after installing the shirt collar 6, remove the elongated hole 9 at the top of the connecting flapper 8 from the cut-and-raised piece 11 of the outer frame 1. Release the Connectin Darepper 8.

Therefore, in the above-mentioned state after installation, if you operate a switch (not shown) to energize the motor 3, the ventilation blades 4, which are rotated by starting the motor 3, will be activated.
sucks air from the indoor side and applies wind pressure to the outdoor side to the shirt shutter 6.

Then, due to the wind pressure, the shirt holder 6 moves around the fulcrum of the rivet 14 and the shaft pin 7 on the shirt holder mounting piece 12.
While the connecting flapper 8 is lowered via the shirt flap attachment piece 12, it is rotated upward and opened.

Therefore, after this, the opened shirt 6 portion, that is, the outer frame 1
The indoor air is discharged to the outdoor side through the outdoor side opening of the shutter 6, and while this operation continues, the shirt shutter 6 is maintained in the above-mentioned open state.

However, if the power to the motor 3 is cut off at this point, the ventilation blades 4
When the shirt stopper stops rotating, the shirt stopper 6 is also released from the previous wind pressure, and the shirt stopper 6 is then moved around the support points of the previous rivet 14 and the shaft pin 7 due to its own weight, also accompanied by the shirt stopper attachment piece 12, and this shirt stopper 6 is also released from the previous wind pressure. While the connecting flap 8 is raised and returned via the attachment piece 12 in the opposite manner to the above, it is rotated downward to return to the closed state.

Next, when removing the shirt collar 6, first unscrew the screws 18 for each piece of the shirt collar 6 and remove it. 12 through the long hole 16.

After that, by removing the hole 17 from the shaft pin 7, the shirt holder 6 can be removed.
One sheet can be removed as desired, and therefore, the remaining two sheets of the shirt shirt 6 can be similarly removed without bending each sheet one by one, and without the trouble of removing the ventilation blades 4, motor 3, etc. It can be easily and quickly removed from the outside.

In this embodiment, as is clear from the above, not only can all the shirt flaps 6 be easily and quickly removed, but also one piece can be separated from the connector sluiceper 8, that is, the shirt flap coupling body, and can be removed independently. Because it can be removed,
Even when cleaning to remove oil stains and the like after removal, each piece of the shirt shirt 6 can be handled and cleaned as desired, making it more comfortable to use after reinstallation.

Note that the reinstallation of the removed shirt stopper 6 may be done in the same manner as the initial installation described above.

Here, FIG. 4 shows a different embodiment of the present invention.
This device differs from the previous one in that the opening/closing of the shutter 6 is performed manually in conjunction with the operation/stopping of the ventilation fan and the energization/disconnection of the motor 3. For this reason, the indoor opening of the outer frame 1 is closed. At the lower corner is a switch box 22 that constitutes a switch mechanism for controlling the energization and disconnection of the motor 3, and the upper end of the pull plate 23 passing through the box 22 and the horizontal extension of the connecting taper 8 are located at the lower corner. A ring 25 connects the notch groove 24 at the front end of the portion 8a.

Further, in the same figure, 26 is a spring stretched between the upper part of the connecting flapper 8 and the upper part of the outer frame 1 located further above this in order to apply a closing force to the shirt flap 6, and 27 is a spring that is stretched between the upper part of the outer frame 1 further above this to apply a closing force to the shirt flap 6. By pulling down the pull plate 23 with this pull cord 27, a switch (not shown) in the switch box 22 is activated to turn on or off the motor 3, and at the same time, the pull cord 27 is used to pull down the pull plate 23. The connecting flapper 8 is raised and lowered to open and close the shirt flap 6.

Furthermore, in the same figure, the hole 19 of the shirt shirt 6 and the cut and raised piece 2 are shown.
Although there are differences from the above in the vertical relationship between the screw hole 15 and the elongated hole 16 of the screw hole 15 and the elongated hole 16 of the shirt attaching piece 12 and the shape of the elongated hole 16 among them, there are differences from the above, but each other shirt attaching piece 12 can be attached and detached in place of the aforementioned rivet 14. This embodiment differs from the previous embodiment in that it is pivotally connected to the outer frame 1 via a shaft pin 28, so that the connector sag 8 can be removed from the outer frame 1 together with the shirt flap attachment pieces 12.

Even if this change is made, basically the same effect as described above can be obtained.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings; for example, it is possible to easily match the upper hole 19 and the screw hole 15 of the shirt shirt 6, which can be attached from the outside. If possible, it is possible to omit the cut-and-raised piece 20 and the elongated hole 16, and it is also possible to attach both sides of the shirt collar 6 via the shirt flap attachment pieces 12, and of course it is possible to omit the cut-and-raised piece 20 and the elongated hole 16. It is also possible to combine it with equipment other than ventilation fans or apply it to the shirtter device alone.
The specific number of sheets, etc. may be changed as appropriate without departing from the gist.

As explained above, the present invention is for attaching a plurality of shirt ties to a shirt tie support so that they can be opened and closed, and includes a shirt tie connecting body provided along with the shirt tie support, and a shirt tie corresponding to the number of shirt ties. Shirt flap attachment pieces, each of which is connected to the shirt flap connecting body and pivoted to the shirt flap support; and a mounting member to which the shirt flap is individually detachably attached to each of the shirt flap mounting pieces from the outside. Accordingly, each of the shirt flaps is indirectly attached to the shirt flap support body by attachment using the mounting tool, and is opened and closed in conjunction with the shirt flap connecting body via the shirt flap attachment piece. This feature allows the shirt shirt to be attached and detached easily and quickly as desired without requiring large separate parts such as mounting plates, and therefore allows for cleaning etc. as desired and provides a comfortable usability. It is possible to provide a shirt attaching device that has excellent practical effects, such as being able to bring about the following effects.
