Description

  The present invention relates to a clip, and more particularly to a clip structure for fixing a filter that covers an exhaust port of a range hood or a ventilation fan.

Generally, a ventilation fan cover or a range hood cover has a structure in which a suction port is covered with a frame body made of synthetic resin or the like, and a filter made of a nonwoven fabric or the like is fixed from the surface. Therefore, it is troublesome to attach the filter to the frame, and there is a problem that the frame is soiled by the oil with the filter.
Moreover, in the conventional ventilation fan cover with a frame, the shape of the cover with which a frame is mounted | worn is decided. Therefore, it has been difficult for general households to freely cut and use wide nonwoven fabrics.
In order to solve the above problems, there is a method of covering the exhaust port with a sheet-like filter, pressing the periphery of the filter with a magnet holder, and fixing the filter to the exhaust port.

  Recent condominiums and the like are concrete structures, so the degree of sealing (airtightness) of the room is high. Therefore, in order to increase the exhaust power of the exhaust port, the fan of the range hood has become powerful. When a thin non-woven filter is attached around a ventilation fan or a range hood, if the fan is strong, the thin filter is likely to be sucked into the fan. And it is necessary to clean the duct into which the filter has been sucked.

Therefore, it is conceivable to use a thick non-woven filter. However, a thick non-woven filter has a problem that even if it is pressed by a magnet holder and attached to the exhaust port, the magnetic force of the magnet holder is weakened by the thick filter and the filter cannot be fixed.
Even if a surface fastener is used in place of the magnet holder, if the thick filter is soiled with oil, the thick filter containing oil becomes heavy, causing a problem that the filter falls.
Therefore, it is conceivable to use a clip such as a clothespin with a leaf spring (see Patent Document 1) and fix the filter around the exhaust port of the ventilation fan or the range hood.
Japanese Utility Model Publication No.42-7965

However, even when a clip such as a clothespin is used, the leaf spring is curved only in a certain direction. If the amount of deformation of the leaf spring becomes large or if the bending is repeated only in one direction, the leaf spring becomes addictive. The leaf spring that is elastically deformed is a leaf spring that is plastically deformed. And because of its habit, it is difficult for the leaf spring to return to the state before biasing (before bending). As a result, the meshing force of the clip is reduced. Moreover, it is necessary to return the leaf spring in which the habit occurred to its original state.
Therefore, even if the filter is attached to the exhaust port using a clip, the meshing force of the clip is weakened, causing a problem that the filter cannot be fixed.

  Therefore, as a result of diligent efforts, the inventor of the present application has found a clip that can be used for a long time without reducing the meshing force if a clip provided with a stopper that regulates the amount of deformation of the leaf spring is used. Completed.

An object of the present invention is to provide a clip for fixing a freely cut filter around an exhaust port of a ventilation fan or a range hood.
Another object of the present invention is to provide a clip for fixing a thick filter or a thin filter around an exhaust port.
Furthermore, an object of the present invention is to provide a clip that can be easily attached to and detached from the filter, can be easily fixed to the exhaust port of the filter, and can be securely attached.

Further, the base end of the leaf spring is integrally formed with one of the pair of sandwiching pieces, and the distal end of the leaf spring is latched by the latching protrusion provided on the other of the pair of sandwiching pieces. .
Furthermore, a stopper that restricts the amount of deformation of the leaf spring is disposed on one of the pair of sandwiching pieces when the pressing portion of the remaining other sandwiching piece comes into contact therewith. Thereby, the deformation amount of the leaf | plate spring provided in a pair of clamping piece can be suppressed. Further, by suppressing the amount of deformation of the leaf spring, it is possible to make the habit of the leaf spring less likely to occur. That is, the stopper has a function of preventing the leaf spring from being bent excessively and holding the leaf spring so as to always return to the state before the biasing.
As a result, even if the clip according to the present invention is used and the periphery of the filter is clamped and the release is repeated, the habituation of the leaf spring can be made difficult to occur.

  According to a second aspect of the present invention, there are provided two hooking projections spaced apart from each other by a predetermined distance in the length direction of the clip piece, and the leaf spring is provided for any of the two hooking projections. The tip of the leaf spring can be hooked, and when the tip of the leaf spring is hooked on one of the hooking projections, the leaf spring is bent and deformed, and when the tip of the leaf spring is hooked on the other hooking projection.

As a result, the habituation of the leaf spring can be made less likely to occur than when the leaf spring is bent only in a certain direction. That is, the engagement force of the clip is not reduced.

  The invention according to claim 3 is the clip according to claim 1 or claim 2, wherein each of the clip portions of the pair of clip pieces has a comb-tooth structure with a small thickness.

According to the invention described in claim 3, each sandwiching portion of the pair of sandwiching pieces has a comb-tooth structure with a thin wall thickness. Thereby, the length of a comb tooth can be shortened, for example using scissors.
Thereby, if the length of the comb teeth is shortened with scissors, the gap portion of the meshing portion is widened, so that a thick filter can be sandwiched between the clips and fixed around the exhaust port.

According to the present invention, the leaf spring provided on the pair of sandwiching pieces has a base end integrally formed with one of the pair of sandwiching pieces, and the tip of the leaf spring is formed on the other of the pair of sandwiching pieces. It is latched by the arranged latching protrusion.
Furthermore, a stopper that restricts the amount of deformation of the leaf spring is disposed on one of the pair of sandwiching pieces by contacting the pressing portion of the other sandwiching piece. Thereby, the deformation amount of the leaf | plate spring provided in a pair of clamping piece can be suppressed. By suppressing the amount of deformation of the leaf spring, the habituation of the leaf spring can be made difficult to occur.
As a result, even if the clip according to the present invention is used and the periphery of the filter is clamped and the release is repeated, the habituation of the leaf spring can be made difficult to occur.

A first embodiment of the present invention will be described below with reference to FIGS.
As shown in FIGS. 1 and 2, the clip 10 according to the present invention is composed of a pair of plastic clip pieces (referred to as a first clip piece 11 and a second clip piece 12). The pair of sandwich pieces can be manufactured at low cost by using plastic without using metal.
As shown in FIG. 3, among the pair of sandwiching pieces, the first sandwiching piece 11 (one sandwiching piece) has a shape in which a flat plate is abbreviated (bent to be rounded and bent at an obtuse angle). is doing. A pin 16 is provided at the center of the first clip piece 11 so as to protrude in a columnar shape in a direction perpendicular to the length direction of the clip piece.
On the other hand, as shown in FIG. 4, the second sandwich piece has a main body formed with a thicker pressing portion side than the sandwiching portion side. A semi-cylindrical pin receiving portion 17 into which the pin 16 provided on the first sandwiching piece 11 is fitted is provided at the center of the second sandwiching piece 12 (the other sandwiching piece). Thereby, as shown in FIG. 1 and FIG. 2, the clip 10 in which the first sandwiching piece 11 and the second sandwiching piece are pin-coupled at their intermediate portions can be obtained.
A pinching portion is provided on one end side of the pin coupling portion of the pair of pinching pieces. The sandwiching portion is a portion for sandwiching a non-woven filter 33 attached to the ventilation fan or the range hood 30.
Further, a pressing portion is provided on the other end side from the pin coupling portion of the pair of sandwiching pieces. The pressing portion is a portion that presses the portion or releases the pressing to sandwich the non-woven fabric filter 33 between the sandwiching portions or to release the sandwiching.

Further, the pair of sandwiching pieces are provided with a leaf spring 13 that urges the sandwiching parts to approach each other. Specifically, the leaf spring 13 has a flat plate shape, and the base end thereof is formed integrally with the first sandwiching piece 11. That is, as shown in FIG. 3, the leaf spring 13 is formed such that its proximal end is provided at the pressing portion of the first sandwiching piece 11 and its distal end extends from the proximal end in the direction of the second sandwiching piece 12. Has been.
Further, comb teeth 15 extending downward are disposed in the sandwiching portion of the first sandwiching piece 11.
Further, the pressing portion of the first clip piece 11 is provided with a non-slip 18 that protrudes into a substantially rectangular shape that prevents slipping when pressed with a finger. Moreover, the cavity 23 which prevents the slip of the finger when pressing is formed in the pressing part.

As shown in FIG. 4, two stoppers 14 projecting in a cylindrical shape toward the pressing portion of the first sandwiching piece 11 are provided on the pressing portion side of the second sandwiching piece 12 by a predetermined distance in the width direction. And spaced apart.
Further, two latching protrusions 19 and 20 are provided in the pressing portion of the second clip piece 12 with a predetermined distance apart from each other in the length direction of the second clip piece 12. The tip of the leaf spring 13 can be hooked on one latching protrusion 19 and can be latched on the other latching protrusion 20.
Further, comb teeth 15 extending in the direction of the sandwiching portion of the first sandwiching piece 11 are disposed at the sandwiching portion of the second sandwiching piece 12.
Furthermore, as shown in FIG. 5, a rectangular hole 21 is provided in the pressing portion on the back surface of the second clip piece 12. A ferrite magnet piece 22 is disposed in the hole 21.

Next, a method for attaching the filter 33 using the clip 10 of the present invention will be described.
First, a thick filter 33 is prepared. The filter 33 is a flame-retardant nonwoven fabric. The thickness of the filter 33 is approximately 10 mm.
Next, as shown in FIG. 7, the filter 33 is cut to a size larger than the exhaust port, and is adjusted to the size of the exhaust port to be attached. Thereafter, the clip 10 according to the present invention to be attached around the filter 33 is prepared.

Next, a thumb is applied to the pressing portion of the first clip piece 11 and a forefinger is applied to the pressing portion of the second clip piece 12. Further, the first pinching piece 11 is pressed with the thumb while supporting the pressing portion of the second pinching piece 12 with the index finger. As a result, the pressing portion of the first sandwiching piece 11 and the pressing portion of the second sandwiching piece 12 approach each other, and the approaching between the sandwiching portion of the first sandwiching piece 11 and the sandwiching portion of the second sandwiching piece 12. Is released.
At this time, the leaf spring 13 is released from the urging force that the sandwiching portions approach each other, and is bent and deformed in the thickness direction.
And the stopper 14 which controls the deformation amount of the said leaf | plate spring 13 is arrange | positioned by the press part of the 2nd clip piece 12 contacting the 1st clip piece 11 of the clip 10 which concerns on this invention. Yes. Thereby, the deformation amount of the leaf | plate spring 13 provided in a pair of clamping piece can be suppressed. By suppressing the deformation amount of the leaf spring 13, the addictiveness of the leaf spring 13 can be made difficult to occur. That is, it is possible to prevent excessive bending beyond the predetermined limit of the leaf spring.
If the stopper 14 is not provided, the plate spring 13 has a large amount of deformation, and the function of returning to the original state does not work.

In the pressed state, the clip 10 is positioned around the filter 33. Then, the thumb is released from the pressing portion of the first pinching piece 11 to release the pressing of the first pinching piece 11. As a result, the leaf spring 13 is urged so that the sandwiched portions approach each other, and the clip 10 is attached around the filter 33. As a result, the filter 33 can be easily attached with the clip 10.
And as shown in FIG. 8, the filter 33 pinched | interposed with the clip 10 is covered on the exhaust port of the deep type range hood 30, for example. And the clip 10 is attached to the surrounding frame 31 of the exhaust port of the range hood 30 with the magnet 22 provided in the back surface. Accordingly, the thick non-woven filter 33 can be attached around the exhaust port of the range hood 30.
By suppressing the amount of deformation of the leaf spring 13 with the stopper 14, the habituation of the leaf spring 13 can be made difficult to occur even when the periphery of the filter 33 is sandwiched and released repeatedly.

As shown in FIG. 4, two hooking protrusions 19 and 20 are provided on the second sandwiching piece 12 so as to be separated from each other by a predetermined distance. FIG. 1 shows the clip 10 in a state where the leaf spring 13 is hooked on the hooking protrusion 19 on the pressing portion side.
