Description

  The present invention relates to a stretchable nonwoven fabric filter holding frame in which a nonwoven fabric filter frame can be stretched vertically and horizontally and the filter surface can be held substantially uniformly.

  Conventionally, a nonwoven fabric filter for removing oil smoke used in a range hood has been attached from below using a magic tape or a magnet.

  The method using the frame for the oil-smoke-removing non-woven fabric filter is not popular because the range hood has various sizes, so a filter frame corresponding to the size of the range hood must be used. .

  The conventional method of using a non-woven fabric filter applied from the bottom is not clean because the filter may sag or the magnet is obstructive due to insufficient adhesion strength due to oil adhering to the adhesive part. In addition, the method of using the filter frame has to prepare frames of various sizes, which increases the stock burden and is difficult to spread.

  The present invention is a stretchable nonwoven fabric with a surface holding piece capable of supporting a range hood of various sizes and capable of holding the filter surface almost uniformly, by expanding and contracting the frame for the oil and smoke removal nonwoven fabric vertically and horizontally. The above-mentioned drawbacks are to be solved by the filter holding frame.

  The stretchable nonwoven filter holding frame according to the present invention is composed of four substantially triangular holding members each provided with a substantially linear surface holding piece at the front end of a substantially L-shaped frame piece in plan view. By holding the frame pieces of the holding member slidably and forming a substantially square shape, the frame expands and contracts vertically and horizontally, and the surface holding that holds the filter attached to the inside of the frame piece by the four surface holding pieces It is characterized by forming a part.

  Further, the four holding members are connected to each other on the upper side of the opposing two holding member side frame pieces, and on the lower side of the adjacent two holding member side frame pieces. Since the pieces can largely intersect with each other without hindrance, the filter surface can be held almost uniformly even when the frame expands and contracts vertically and horizontally.

  Further, in order to fix the filter attached to the holding frame in a sandwich shape, the substantially triangular back surface holding member is composed of four substantially linear bodies, and is substantially triangular. A pipe or ring or the like through which a substantially linear body passes is provided at the front end of the L-shape, and the adjacent substantially triangular L-shaped linear bodies are connected to the slide structure through the pipes or rings and the like. It is characterized in that a substantially square-shaped back-and-forth back fixing frame formed in the above-mentioned manner is formed.

  As described above, the stretchable nonwoven filter holding frame of the present invention is not limited to the vertical and horizontal expansion and contraction of the frame, and the both sides of the filter are substantially linear surface holding pieces regardless of the expansion and contraction of the frame. By being able to be fixed, it is possible to deal with range hoods of various sizes.

  Compared to a range hood with a non-smoked non-woven filter attached from the bottom, it is clean and beautiful.

  After the filter is fitted in the filter holding frame, the filter between the holding frame and the surface holding piece is held by holding it with the holding frame's hook by pressing it with a back and forth fixing frame that uses a substantially linear frame piece. Both sides can be fixed by sandwiching them in a saddle shape, and various sizes can be accommodated.

  The stretchable nonwoven fabric filter holding frame according to the present invention has a frame piece 2 having a substantially unequal angled cross section as shown in FIG. It consists of four holding members 1 provided with surface holding pieces 3 of linear bodies. Bolt holes 5 are made in the frame pieces 2 of the holding members 1a, 1d, and the frame pieces of the holding members 1b, 1c. 2 has an elongated hole 4 for sliding, a bolt 6 is passed through the bolt hole 5, and a frame is slid by loosely stopping with a nut 6b through the elongated hole 4 for sliding. In addition, the size can be fixed by tightening the nut 6b. The slide structure includes a frame piece structure that can slide without making a hole.

  The four holding members are slidably connected with the frame pieces 2 of the two holding members 1b and 1c facing each other on the upper side and the frame pieces 2 of the two adjacent holding members 1a and 1d on the lower side. By doing so, the surface holding pieces 3 can largely intersect with each other without hindrance so that the filter surface can be held almost uniformly by the interlocking surface holding pieces 3 even when the frame is expanded and contracted vertically and horizontally. Alternatively, the combination of the frame pieces 2 of the four holding members may have a structure in which only the four right sides or left sides can be slid integrally with the lower side or the upper side, and the same applies to the surface holding pieces.

  In order to fix the back surface of the filter 11 attached to the holding frame in a sandwich shape, instead of the substantially L-shaped frame piece 2 in a plan view, the filter 11 is composed of a substantially linear body, and is composed of eight approximately triangular shapes that are all substantially linear bodies. When the substantially triangular shape 8 is created, a pipe 9 or a ring through which the substantially linear body passes is provided at the front end of the substantially linear frame piece that sandwiches a substantially right angle, and the substantially linear bodies are mutually adjacent to the adjacent linear body ring. By fastening with welding 10 or the like after passing through, it is possible to obtain a back-side fixed frame figure 6 that expands and contracts formed into a substantially square shape of a slide structure having four substantially triangular shapes.

  After the filter is inserted into the frame, both sides of the filter are fixed by pressing the filter with the back fixed frame that expands and contracts and fastens to the frame hook 7, and the size of the back fixed frame that expands and contracts is also fixed. A stretchable non-woven filter frame can be made that can be used with any range hood.

  The substantially triangular shape may be a method of manufacturing a substantially triangular shape by punching a plate material, and includes a shape in which a hypotenuse of a substantially triangular shape is bent or a square shape.

  An embodiment will be described below with reference to the accompanying drawings. FIG. 1 shows four holding members 1 provided with a substantially linear body 3 at the front end of a substantially L-shaped frame piece 2 in plan view, and bolt holes 5 are provided at four frame pieces of two holding members 1a and 1d. And four long holes 4 for sliding are made in the frame pieces of the remaining two holding members 1b and 1c. The cross-sectional view of the frame piece 2 having a substantially L shape in plan view is a substantially unequal angle of the frame piece 2 of FIG.

  The combination of the four holding members 1 is such that the two holding members 1b and 1c facing each other are on the upper side and the adjacent two substantially triangular shapes 1a and 1d are on the lower side, and the frame pieces are overlapped with each other and loosely stopped with bolts 6 and nuts 6b. Thus, the holding frame 1 having a structure in which the frame can be slid without any obstacle on the surface holding piece is obtained, and the dimensions are fixed by tightening the bolt 6 and the nut 6b.

  The embodiment when the holding frame is slid has the shape of FIG. 2 when the four sides of the frame are contracted and reduced, and has the shape of FIG. 3 when the four sides of the frame are extended and enlarged. When the two sides of the frame are extended, the rectangle shown in FIG. 4 is obtained, and in either case, one side of the filter can be held almost uniformly by the surface holding piece interlocking with the frame.

  In order to hold down the opposite surface of the filter attached to the frame, a substantially linear body is used for the frame piece 2 having the above-described structure, and the substantially L-shaped tip of the substantially triangular body 8 as shown in FIG. FIG. 6 shows the case where the rear surface fixing frame formed in a substantially rectangular shape is provided through the pipe 9 so that the adjacent substantially triangular triangles 8 can be slid, and FIG. 7 shows the enlarged state. When it is rectangular, it looks like FIG.

  FIG. 9 is a cross-sectional view of an image in which the filter 11 is set on the holding frame. The cross-section of the frame piece 2 is an unequal side angle, the structure of the frame pieces 2 overlapping, the surface holding piece 3, and the hook 7 that holds the back surface fixing frame. Etc. are drawn.

  Slide the holding frame to the size of the range hood frame or the size of the attached metal filter by sliding the holding frame to the extendable range hood filter and tighten the bolt 6 nut 6b. Fit the frame to the cut frame with scissors or the like. Match the size of the back surface fixing frame to the holding frame and fasten it to the hook 7 attached to the holding frame to fix the filter 11. After that, it is completed in the groove of the range hood.
