In FIG. 1, this range hood filter attachment comprises a panel 1, a range hood filter 2, a holding tool 3 for sandwiching the range hood filter 2 in the panel 1, and at least one or more auxiliary pieces 4. Is configured.

As shown in FIG. 3, the panel 1 is formed in a hollow rectangular frame shape as a whole. That is, specifically, the panel 1 is configured by connecting vertical and horizontal frame side portions 10a to 10d made of, for example, aluminum or aluminum alloy, and a rectangular opening 13 is provided inside these. Has been formed. The frame side portions 10a to 1
The inner surface of each part of 0d has inward projecting edge portions 11a to 11d for supporting the left and right side edge portions 2a, 2b and the upper and lower side edge portions 2c, 2d of the range hood filter 2, respectively.
Is provided. In addition, a pair of left and right frame sides 10a, 1
0b has a small-diameter shaft body 12 between the substantially central portions in the longitudinal direction.
Has been erected. This shaft body 12 is also for abutting and supporting the range hood filter 2. When the range hood filter 2 is attached to the panel 1, the side edge portions 2a to 2d of the filter 2 are attached to the inward protruding edge portion 11a of the panel 1.
It is possible to bring the central portion of the filter 2 into contact with the shaft body 12 while making contact with each of the shaft members 12 to 11d. Accordingly, the filter 2 can be appropriately arranged on the back surface side of the panel 1 without unintentionally protruding to the front surface side of the panel 1.

Of the frame side portions 10a to 10d, a pair of upper and lower frame side portions 10c and 10d are formed in a sectional shape different from that of the pair of left and right frame side portions 10a and 10b formed in a substantially L-shaped cross section. Has been done. These pair of frame side portions 10c, 10
As shown in FIG. 4, d is a protrusion 16 having an inverted L-shaped cross section on the back surface (corresponding to the top surface in FIG. 4) of the flat plate portion 15 having a flat plate shape, and a cross L-shaped first
And the engaging projection 5 of FIG. The protruding piece 1
6 has a concave portion 17 formed between the flat portion 15 and
The upper and lower end portions 14a and 14b (corresponding to the left and right end portions in FIG. 4) of the one frame side portion 10a and 10b are fitted and connected in the recess 17.

The first engaging projection 5 has an upright portion 50 upright from the outer edge of the flat plate portion 15, and the upright portion 50.
Has a bending piece portion 51 continuously provided at the tip of
The bent piece portion 51 is formed so as to extend inward of the panel 1 from the tip portion of the standing portion 50.

The first engaging projection 5 and the protruding piece portion 16 are formed in series along the longitudinal direction of the frame side portions 10c and 10d, and the cross-sectional shape of each portion of the frame side portions 10c and 10d is as follows. It is uniform. Therefore, these frame side portions 10c,
It is possible to manufacture 10d by extrusion molding of aluminum or aluminum alloy. Of course, the other frame side part 10
The a and 10b can also be manufactured by extrusion molding.

In FIG. 3, the auxiliary piece 4 is made of, for example, the same material as that of the panel 1 such as aluminum or aluminum alloy, and the entire length L thereof is the frame side portion 10c of the panel 1.
It is set to be substantially the same as the length La of 10d. At one side edge of the auxiliary piece 4, the auxiliary piece 4 is attached to the first side of the panel 1.
Second engaging projection 6 for engaging with the engaging projection 5 of
And a third engaging projection 7 different from this is formed in series on the other side edge.

The second engaging projection 6 of the auxiliary piece 4 is, for example, as shown in FIG. 5, an upright portion 60 which stands up from one side edge of the auxiliary piece 4 to its back surface side (upper surface side in FIG. 5). The upright portion 60 has a hook-shaped bent piece portion 61 continuously provided at the tip thereof. The hook-shaped bent piece portion 61 is bent in a substantially U-shaped cross section, and a concave groove portion 62 is formed between the base portion 61a and the tip end portion 61b of the bent piece portion 61. . The concave groove portion 62 is for slidingly fitting the bent piece portion 51 of the first engaging projection 5 shown in FIG. Therefore, the opening width S is essentially formed to be substantially the same as or slightly larger than the thickness t of the bending piece portion 51, but in the present embodiment, the tip portion 61b is formed at a slight angle at the base portion. It is inclined so as to approach the 61a side, and the opening width S of the concave groove portion 62 is formed to be slightly narrower than the thickness t of the bending piece portion 51.

The third engaging projection 7 of the auxiliary piece 4 is engaged with the second engaging projection 6 provided on another auxiliary piece formed in the same size and shape as the auxiliary piece 4. It is for the purpose of planning. Therefore, the specific configuration of the third engagement protrusion 7 may be formed in the same manner as the first engagement protrusion 5 provided on the panel 1, and has, for example, an inverted L-shaped cross section. The upright portion 70 and the bent piece portion 71 continuously provided at the tip of the upright portion 70 are configured.

The second engaging projection 6 and the third engaging piece 4 of the auxiliary piece 4
The engaging projection 7 has a uniform cross-sectional shape at various places, and the entire auxiliary piece 4 is formed to have a uniform cross-sectional shape at each place.
Therefore, the auxiliary piece 4 can also be extruded.

Although FIG. 1 and FIG. 3 show two auxiliary pieces 4 and 4, these auxiliary pieces 4 and 4 are shown.
However, only the arrangement directions thereof are different, and the two auxiliary pieces 4 and 4 have substantially the same configuration.

In FIG. 3, as the range hood filter 2, various conventionally known ones can be used. As a specific example, glass fiber having flame resistance is used.

The retainer 3 has a resilience slightly smaller than that of the panel 1 by appropriately bending a wire-like metal member made of stainless steel or the same material as the panel 1. It is formed as a frame. Protrusions 30 for attaching the pressing tool 3 to the back side of the panel 1 are appropriately formed at both ends of the pressing tool 3. That is, as shown in FIG. 1 and FIG.
The pressing tool 3 has the range hood filter 2 arranged on the back surface side of the panel 1 and then the protruding portion 3 of the pressing tool 3.
0 can be attached to the panel 1 by locking 0 to the projecting pieces 16 of the frame side portions 10c and 10d of the panel 1. As a result, the range hood filter 2 can be held by being sandwiched between the pressing tool 3 and the panel 1.

Next, an example of use and operation of the attachment for a range hood filter having the above structure will be described.

First, in FIG. 8, the range hood 8 attached to the wall of the kitchen or the like is usually provided with a frame 80 for attaching the attachment for the range hood filter. Although the specific size of the frame 80 differs depending on the manufacturer of the range hood, the size of the attachment A assembled in the form shown in FIG. 1 matches the frame 80. Sometimes, this attachment A is used as it is for the frame portion 80.
You can install it on.

On the other hand, the vertical dimension L1 of the attachment A may be smaller than the vertical dimension L3 of the frame portion 80 of the range hood 8. In this case, for example, as shown in FIG. 6, the upper and lower frame sides 10c and 10d of the panel 1 are
The auxiliary pieces 4 and 4 may be connected to each of them. These auxiliary pieces 4 and 4 are connected by making one end of the second engaging projection 6 of the auxiliary piece 4 face one end of the first engaging projection 5 of the panel 1 as shown by an arrow N in FIG. Therefore, as shown in FIG. 7, the auxiliary piece 4 and the panel 1 are mutually connected so that the bent piece portion 51 of the first engaging projection 5 is fitted into the concave groove portion 62 of the second engaging projection 6. Just slide it.

In the engaged state of the first engagement projection 5 and the second engagement projection 6 as shown in FIG. 7, the auxiliary piece 4 does not easily come off from the panel 1, and both of them do not come off. Can be reliably connected. Further, the tip end portion 61b of the hook-shaped bent piece portion 61 of the second engagement projection 6 is indicated by an arrow with respect to the bent piece portion 51 of the first engagement projection 5 that is forcibly fitted into the concave groove portion 62. Since the elastic restoring force acting in the a direction presses the auxiliary piece 4, the auxiliary piece 4 is appropriately prevented from easily sliding along the width direction of the panel 1.
Therefore, the auxiliary piece 4 is attached to the upper and lower frame side portions 10 of the panel 1.
It is possible to securely arrange them by arranging them properly on the outside of the c and 10d.

In this way, by connecting both or one of the two auxiliary pieces 4 and 4, the entire vertical width L2 of the attachment A1 including the auxiliary piece 4 and the auxiliary piece 4 are provided. Vertical width L1 of attachment A that is not included
Can be greater than. Therefore, the attachment A1 can be made to match the size of the frame portion 80 of the range hood 8 and can be properly attached to the range hood 8 and used. It is possible to eliminate or significantly reduce the need to individually prepare attachments of different sizes corresponding to different types of range hood 8.

Further, when the vertical width of the entire attachment is expanded as described above, the size of the vertical width may still be insufficient only by connecting the two auxiliary pieces 4 and 4. In such a case, as shown by the phantom line in FIG. 7, the third engaging projection 7 of the auxiliary piece 4 connected to the panel 1 is attached to the second engagement portion of the other auxiliary piece 4 (4a). Combined projection 6
By engaging these two auxiliary pieces 4, 4
It suffices to connect a. Similar to the connection between the panel 1 and the auxiliary piece 4, the connection between the two auxiliary pieces 4 and 4a can be performed simply and reliably.

As described above, if the other auxiliary piece 4a is further connected to the auxiliary piece 4 connected to the panel 1, the vertical width of the entire attachment can be further expanded. The auxiliary piece 4a also has a third
This auxiliary piece 4a is provided with the engaging projection 7 of
It is also possible to add another auxiliary piece to and to connect. Therefore, even when the size of the frame portion 80 of the range hood 8 is considerably larger than the size of the panel 1, the vertical width of the entire attachment can be correspondingly increased and appropriate measures can be taken.

In the above embodiment, of the four frame side portions 10a to 10d of the panel 1, the two upper and lower frame side portions 10a to 10d are used.
Although the first engaging projections 5 are provided on c and 10d, the present invention is not necessarily limited to this. In the present invention, by providing the first engaging projections 5 at all positions of the four frame side portions 10a to 10d, the vertical width of the attachment can be changed, and the horizontal width can be appropriately increased or decreased. I don't care. In addition, the four frame sides 10a to
Of the 10d, for example, the first engaging projection 5 may be provided only on one side of the frame. Even in this case, the vertical width or the horizontal width of the attachment is changed by connecting the auxiliary piece 4 to the frame side portion provided with the first engaging projection 5 to achieve the object of the present invention. It is possible.

Further, according to the present invention, the concrete configurations of the first engaging portion of the panel 1 and the second engaging portion of the auxiliary piece 4 are also the same as the first engaging projection 5 shown in the above embodiment. It is not limited to the second engagement projection 6 or the second engagement projection 6 .

Furthermore, the present invention is not limited to the specific configuration of the panel in the above embodiment. For example, the front surface of the panel may be configured as a type of panel formed like a wire mesh, and as a specific means for attaching and holding the range hood filter to this panel,
It may be performed by a means different from the pressing tool 3.

In addition, the specific construction of each part of the attachment for a range hood filter according to the present invention can be modified in various ways. There are two ways to attach the attachment to the range hood: attaching the attachment along the vertical direction, or attaching it with a slight inclination to the vertical direction, and attaching it with the attachment lying substantially horizontally. However, the invention of the present application can be applied to any case, and the attachment aspect of the attachment does not matter in the invention of the present application.
