[Industrial applications]

 The present invention relates to a ventilator cover attachment, and more particularly to a ventilator cover attachment that is easy and safe to handle.

[0002]

[Prior art]

 Generally, various ventilation fans are used to discharge oily smoke, soot, etc. generated in a domestic kitchen or the like to the outside of the room. This exhaust fan is apt to be contaminated by oily smoke and is easily soiled. To prevent such contamination, a ventilation fan cover that covers the exhaust fan is used.

The ventilating fan cover is attached to the front surface of the ventilating fan to adhere oil smoke or the like that causes dirt, and the ventilating fan cover itself becomes dirty instead of the ventilating fan. If the exhaust fan cover becomes dirty and becomes clogged or clogged when the exhaust fan is in use, the dirty exhaust fan cover is removed from the exhaust fan and a new clean exhaust fan cover is attached to the exhaust fan. .

For this reason, various double-sided tapes have been conventionally used as a fitting for a ventilation fan cover for attaching a ventilation fan cover to a ventilation fan in a replaceable manner for reasons such as simplicity.

By the way, in a device using a double-sided tape as a fixture for such a ventilation fan cover, since the ventilation fan and the ventilation fan cover are fixed by the adhesive force of the double-sided tape, the adhesive force of the double-sided tape is If it is weak or the adhesive strength of the double-sided tape deteriorates over time, the ventilation fan cover may fall off the ventilation fan during use. In addition, if the double-sided tape has a strong adhesive force, there is a problem in that the ventilation fan cover is difficult to come off from the ventilation fan when the ventilation fan cover is replaced.

Therefore, in order to deal with such a problem, there has been proposed a ventilation fan cover fixture integrally formed so that the ventilation fan and the ventilation fan cover can be easily attached and detached.

FIG. 4 shows an example of such a conventional ventilating fan cover mounting tool. The ventilating fan cover mounting tool 1 is engaged with a hole provided near an outer edge of the ventilation fan cover. Locking part 2, coil spring part 3 which is an elastic member continuously connected to the first locking part 2, and handle part 4 which is connected to the coil spring part 3 and is coaxial with the coil spring part 3. And a hook-shaped second locking portion 5 which is connected to the handle portion 4 and which is locked to an attachment object such as a frame of a ventilation fan, are integrally formed by one wire member. . Then, when attaching the ventilation fan and the ventilation fan cover, as shown in FIG. 5, first, the first locking portion 2 of the attachment 1 of the ventilation fan cover is inserted into the hole 7 provided near the outer edge of the ventilation fan cover 6. Lock it through. Next, the ventilation fan cover 6 is arranged at a predetermined position of the ventilation fan 8, the grip portion 4 of the attachment 1 of the ventilation fan cover is grasped with a fingertip, and the coil spring portion 3 is pulled and extended to extend the second locking portion 5 to the ventilation fan 8. It suffices to hook it on the frame 9 and lock it.

[0008]

[Problems to be solved by the device]

 However, in the above-described conventional ventilation fan cover fixture 1, the bent portion 10 (FIG. 4) fixed to the attachment target of the second locking portion 5 of the ventilation fan cover fixture 1 is the coil spring portion. Since the coil spring portion 3 is located radially outside of the outer peripheral position of the coil spring 3, the tension of the coil spring portion 3 is applied in a direction different from the axial center direction of the coil spring portion 3, and, for example, the ventilation fan 8 and the ventilation fan cover 6 are attached. There was a problem that the condition was not stable and could easily come off.

Further, as shown in FIG. 4, the coil spring portion 3 formed of a metal in a cylindrical shape is hard to be familiar with the shape of the frame 9 of the ventilation fan 8 corresponding to when the ventilation fan cover 6 is attached, and the ventilation fan 8 is Since it is locked in a state of protruding from the flat side surface of the frame body 9, the external force due to contact or the like is easily received, and the appearance is poor. Further, the coil spring portion 3 which is stretched to fix the ventilation fan 8 and the ventilation fan cover 6 by using elasticity has a risk of pinching a fingertip between the coils when the ventilation fan cover 6 is contracted when the ventilation fan cover 6 is removed. It lacked safety such as having it.

Furthermore, since it is difficult to adjust the amount of expansion, that is, the elastic force of the metal coil spring portion 3, the fixture 1 of the ventilation fan cover 6 that fits the individual ventilation fan 8 that is the object of attachment is selected. Was difficult.

The present invention overcomes the problems of the conventional ones described above, enables easy, safe and quick replacement of the ventilation fan cover with respect to the ventilation fan, and further provides an inexpensive ventilation fan cover mounting tool. The purpose is to
