Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting tool for mounting a ventilation fan filter on a ventilation fan mounting frame.

(Prior Art) Ventilation fans in kitchens, cooking areas, etc. are often equipped with filters in order to prevent the ventilation fan from becoming dirty by removing mist-like oil droplets and the like generated during cooking with oil.
When attaching a filter to the ventilation fan mounting frame, instead of gluing the frame of the filter with double-sided tape or fixing it with screws, use the method disclosed in Utility Model Applications No. 59-4936 and No. 60-135548. An extensible fixture has been proposed which has hooks for locking the ventilation fan mounting frame and the filter frame at both ends of a tension spring.

When installing a ventilation fan filter using the above mounting bracket, lock the hook at one end of the spring to multiple points on the outer periphery of the ventilation fan mounting frame to prevent it from moving forward of the ventilation fan, and then This is done by pulling the hook and stretching the spring while hooking the hook to an appropriate location on the filter frame. The filters mounted in this manner can be removed by removing the hooks from each frame, and can be replaced when the filters become dirty.

(Problem to be solved by the invention) However, when the hooks at both ends of the above-mentioned fixture are respectively locked to the ventilation fan mounting frame and the filter frame, the spring expands and comes into contact with the ventilation fan mounting frame. If there is a step or unevenness between the ventilation fan mounting frame and the filter frame, or if the tension direction is curved rather than in a straight line, the restoring force of the spring may act and the hook part may easily come off. Ta. Furthermore, even when the locking distance at both ends is long, the above-mentioned drawbacks tend to occur and locking becomes difficult.

Therefore, in the present invention, by improving such a mounting tool, it is easier to lock the ventilation fan mounting frame and the filter frame to each locking part, and there is no difference in level between the respective locking parts. An object of the present invention is to provide a mounting tool for a ventilation fan filter that can be easily locked even when the device is far away.

(Means for Solving the Problem) In order to achieve the above object, the present invention has a string-like body whose one end is connected to an end member that is locked to the rear end of a compression spring and extends forward through the spring. , a hook for locking to a filter for a ventilation fan is provided at the tip of the string-like body, a contact portion that engages with the front end of the spring from the front is provided at the front, and the ventilation fan is mounted at the rear of the spring. The present invention is characterized in that the above-mentioned spring is extendably and retractably attached to a spring holding member having a hook part for locking to the frame at the rear part to constitute a mounting tool for a filter for a ventilation fan.

(Example) Next, an example of the present invention will be described based on the drawings.

An example of a fitting for a ventilation fan filter is shown in Figures 1 and 2. Reference numeral 1 denotes a coiled compression spring, and the rear end portion 2 has locking portions 5, 5 that lock onto the circumference of the spring from behind, and a connecting portion protruding inward from the spring 1 at the center portion. 6 is formed on the end member 4 is locked from the rear, and one end of a string-like body 7 is connected to the connecting portion 6, and this string-like body 7 passes through the inside of the spring 1 so that its tip end is connected to the spring 1, and a hook 8 for locking to a filter frame for a ventilation fan is connected to this tip. Reference numeral 9 denotes a holding member for guiding the contraction of the spring 1, and an elongated pin 11 is inserted into the inner side of the spring and extends rearward parallel to the plate 10 at the front end of the elongated plate 10 along the outer surface of the spring 1. The front end of this pin 11 is a contact part 12 of the spring front end 3 when the pin 11 is inserted into the spring 1, and the rear end of this plate 10 has a hook 8 and a mating part. A hook portion 13 for locking to the ventilation fan mounting frame is formed.

When installing the ventilation fan filter 15 on the ventilation fan mounting frame 14 using the ventilation fan filter mounting tool, as shown in FIG. The hook portions 13 of the holding member 9 are respectively locked at the lockable locations so that the mounting tool does not move forward, and the plate 10 of the holding member 9 is attached to the outer surface of the ventilation fan mounting frame 14. Next, the ventilation fan filter 15 is stacked on the ventilation fan mounting frame 14, and the hook 8 at the tip of the mount is pulled toward the front of the ventilation fan, and the spring 1 is compressed in the front of the holding member 9. The hook 8 is locked in a small hole 19 or a locking protrusion provided in the filter frame 18,
Alternatively, the ventilation fan filter 15 can be fixedly attached by making a hole in the filter frame and hooking it. The order in which the ventilation fan filter 15 is attached to the ventilation fan attachment frame 14 is not limited to the above, for example, the ventilation fan filter 15 may be first stacked on the ventilation fan attachment frame 14, and then the mounting tool may be locked.
Also, in the opposite manner to the above, attach the hook portion 13 to the filter frame 1.
8, and the hook 8 may be locked to the ventilation fan mounting frame 14.

According to the above fixture, the compressed spring 1
Since the ventilation fan filter 15 can be attached to the ventilation fan mounting frame 14 via the single string-like body 7 extending from the ventilation fan mounting frame 14 and the filter frame 18
Even if there is a step between the filter frame 18 and the filter frame 18, or even if the gap 17 on the wall side and the small hole 19 of the filter frame 18 are misaligned, the string-like body 7 can bend freely along the frame. The filter frame 18
The hook 8 can be locked extremely easily.

Further, the distance between the gap 17 and the small hole 19 is absorbed by the length of the string-like body 7 and the expansion and contraction of the spring 1, so that the ventilation fan filter 1 can be easily attached. According to the above mounting tool, the filter frame 18
By removing the hook 8 from the small hole 19, the ventilation fan filter 15 can be easily removed.
The ventilation fan filter can be easily replaced when the filter becomes dirty.

Next, a modification of the holding member 9 shown in the above embodiment is shown in FIG. This holding member 20 has a front wall surface 22 and side wall surfaces 23, 23 erected at the front and both sides of an elongated plate 21 along the outer side of the spring 1, and a string-shaped A hole 24 is formed through which the body 7 is inserted, and a locking hook 25 similar to that of the previous embodiment is formed at the lower rear end of the plate 21.
