Description

  The present invention relates to a ventilation fan filter support device and a ventilation fan filter set that are attached to a ventilation port of a ventilation fan.

  Conventionally, a filter is attached to an exhaust port of a ventilation fan in order to prevent contamination of blades (fans), motors, and the like due to intake of contaminated air or oily smoke. As a means for attaching this filter to the ventilation port, for example, a type of ventilation port cover that completely covers the entire ventilation port with a molded frame made of plastic or the like to which the filter is attached is known. However, such a cover for a ventilation port requires a cover of a different size depending on the size of the ventilation port. Therefore, from the viewpoint of reducing the manufacturing cost, a vent cover that can be adjusted according to the size of the vent has been proposed.

  For example, Japanese Utility Model Publication No. 61-6130 (Patent Document 1) discloses a cover body made of a foldable plate and having a ventilation opening, and a filter member attached to the cover body. There is disclosed a filter cover for a ventilation fan that is provided with a cover body that is mounted in a state in which at least a central portion of the cover body is raised. Japanese Patent Application Laid-Open No. 2001-272067 (Patent Document 2) includes a first and second pedestal that has a bonding portion on the back surface side and can be individually joined to both sides of the ventilation fan cover, The first and second pedestals are connected to the base end side via first and second bent portions, respectively, the opening is formed at the center, and the tip portion is connected to be bent to be first and second. There is disclosed a ventilation fan filter holding frame that has two ventilation surface members and is attached to the ventilation fan cover by projecting the tip portions of the first and second ventilation surface materials.

Each of these ventilation fan filter covers (or holding frames) has a structure corresponding to ventilation holes of various sizes by opening and closing a foldable plate-like object, so that these covers can be mounted on a ventilation fan. Hooks, adhesives, magnets, etc. are used. However, in these filter covers, the plate-like object can be freely opened and closed, so that the fixing to the ventilation fan frame and the shape retention are reduced. Or easily detached from the ventilation fan frame. Moreover, it is difficult to reliably and firmly support the filter. In particular, when a thin plate is used, the filter cannot be held firmly while maintaining the shape. In order to prevent such displacement and detachment, fixing with a bolt or the like may be considered. However, in a filter that requires periodic replacement, the operation is complicated.
Japanese Utility Model Publication No. 61-6130 (Japanese Utility Application No. 59-90016) (Claim 1, Specification, page 10, lines 4 to 13, line 1) JP 2001-272067 A (Claim 1, paragraph number [0012], FIGS. 1 to 3)

  Accordingly, an object of the present invention includes a ventilation fan filter support device and a device that can be attached to various sizes of ventilation openings, can maintain a bent shape even when an external force such as wind pressure acts, and can firmly support the filter. It is providing the filter set for ventilation fans.

  Another object of the present invention is to provide a ventilation fan filter support device capable of firmly supporting a filter even if it is thin, and a ventilation fan filter set including this device.

  Still another object of the present invention is to provide a ventilation fan filter support device that can be firmly fixed to a ventilation fan frame by a simple method, and a ventilation fan filter set including this device.

  As a result of intensive studies to achieve the above-mentioned problems, the inventor of the present invention uses a flat support frame having a hinge portion to thereby install a mounting fan in a ventilation fan filter support device that can be attached to ventilation openings of various sizes. It has been found that the filter can be firmly supported when bent to the frame side (inside the flat support frame) and temporarily fixed to the ventilation fan frame, and the present invention has been completed.

  That is, the ventilation fan filter support device according to the present invention includes a ventilated flat support frame having a size capable of covering the opening of the ventilation fan frame, a hinge portion formed in a vertical direction of the support frame, and the support. A ventilation fan filter support device formed on both lateral sides of a frame body and provided with a mounting portion that can be temporarily fixed to the ventilation fan frame, wherein the planar support frame body is formed by the hinge portion by the ventilation fan frame. While being able to bulge out from the body and bendable, the mounting portion can be folded toward the ventilation fan frame side. In this apparatus, a hinge portion extending in the vertical direction is formed at a substantially central portion in the lateral direction of the planar support frame body, and both longitudinal sides of the planar support frame body extend from the hinge portion in the lateral direction. The length in the vertical direction of both sides in the horizontal direction of the planar support frame may be formed larger than the length of the portion. The mounting portion may extend partially or entirely with a predetermined width in the lateral direction from both lateral sides of the planar support frame, and may be temporarily fixed to the ventilation fan frame by temporary fixing means. For example, the attachment portion may be bent inside the planar support frame and temporarily fixed to the ventilation fan frame by temporary fixing means. The apparatus is formed to be foldable at a predetermined width on both sides in the longitudinal direction of the planar support frame, and the planar support frame is folded inward with the planar support frame folded at the hinge. You may provide the reinforcement support part for reinforcing, and the reinforcement part which is formed in the edge part of this reinforcement support part so that it can be bend | folded to the ventilation fan frame side, and is located inside a mounting part in the bending state. The reinforcing portion is foldable to the ventilation fan frame side along the inclined fold in a state where the reinforcing support portion is bent to the ventilation fan frame side, and the attachment portion is folded over the folded reinforcing portion. It may be possible. In addition, although a reinforcement part does not need to be fixed to an attaching part, in order to improve the shape retainability of a support frame, you may fix with temporary fixing means, such as a double-sided adhesive tape. In the device, a notch portion capable of absorbing deformation caused by bending of the hinge portion and the reinforcing support portion may be formed at an intersection portion between the hinge portion and the folding line (fold line) of the reinforcing support portion. .

  The present invention also includes a filter set for a ventilation fan, which is a set of a filter whose peripheral part can be contracted and the apparatus, wherein the filter can cover a side part of the apparatus and the ventilation fan frame.

  In the present invention, since the flat support frame can be bent, it can be attached to a ventilation opening of various sizes, and the attachment portion to the ventilation fan frame is bent to the ventilation fan frame side or inside and temporarily fixed to the ventilation fan frame. Even when an external force such as wind pressure acts on the support frame, the bent shape can be maintained and the filter can be firmly supported. Moreover, if the reinforcement part is bent to the ventilation fan frame side, the longitudinal direction both sides of a reinforcement support part and a planar support frame body can be reinforced. In particular, when bent inside the attachment portion, the attachment portion and the reinforcement portion can be integrated and further reinforced. Therefore, even if the thickness of the planar support frame is thin, the shape retention is high and the filter can be supported firmly. Furthermore, the ventilating port can be covered with a filter by a simpler method by combining it with a filter that can be firmly fixed to the ventilation fan frame by a simple method and whose peripheral portion can contract.

  Hereinafter, the present invention will be described with reference to the accompanying drawings. FIG. 1 is a developed view showing an example of a ventilation fan filter support device of the present invention, FIG. 2 is a perspective view showing a state where the ventilation fan filter support device and the ventilation fan filter of FIG. 1 are attached to a ventilation fan frame, and FIG. 3 is a ventilation fan shown in FIG. FIG. 4 is a partial perspective view showing a state in which the ventilation fan filter support device of FIG. 1 is attached to a ventilation fan frame, and FIG. 5 is another example of the ventilation fan filter support device of the present invention. FIG. 6 is a development view showing still another example of the ventilation fan filter support device of the present invention. For convenience of explanation, the same reference numerals are given to the same members and parts.

  As shown in FIG. 1, the ventilation fan filter support device 1 has a size that can cover the opening of the ventilation fan frame, and is formed in the longitudinal direction of the support frame body 2, and a planar support frame body 2 that can ventilate. Hinge portions 3 formed on both sides of the support frame 2 in the lateral direction, attachment portions 4 that can be bent to the side of the ventilation fan frame by a single crease line 4a, and both sides in the vertical direction of the planar support frame The reinforcing support portion 5 is formed with a predetermined width and can be bent toward the ventilation fan frame side by a single crease line 5a. Further, at both end portions (both corner portions) of the reinforcing support portion 5, reinforcing portions 6 that can be bent toward the ventilation fan frame side by a single crease line 5b are formed. In addition, a notch portion 7 that can absorb deformation caused by bending of the hinge portion 3 and the reinforcing support portion 5 is formed at the intersection of the hinge portion 3 and the crease line 5a. Such an apparatus 1 can be formed of a sheet of plastic, paper or the like.

  More specifically, the hinge portion 3 of the planar support frame body 2 is formed at a substantially central portion in the lateral direction of the planar support frame body 2 and is formed by two fold lines 3a and 3b so as to be easily folded. It is configured. Therefore, the planar support frame body 2 can bulge from the ventilation fan frame body by the hinge portion 3 and be bent into an inverted V-shaped or inverted U-shaped cross section. In the state temporarily fixed to the ventilation fan frame, the planar support frame 2 is bent with the hinge portion 3 as a boundary, and by adjusting the angle, the ventilation holes of various sizes (that is, having various diameter sizes). It can be mounted on a frame having a fan.

  The mounting portion 4 extends from both sides of the support frame 2 in the lateral direction (lateral direction), and has a curved shape whose width decreases from both ends in the vertical direction toward a substantially central portion in the vertical direction. Are formed on the entire lateral sides. That is, the attachment part 4 has a large temporary fixing area at both ends of the lateral side parts. The attachment portion 4 is temporarily attached to the device 1 and is folded back to the ventilation fan frame side (inner side or back side) by a crease line 4a and attached to the surface of the attachment portion 4 (double-sided adhesive tape or the like). ) Can be temporarily fixed to the ventilation fan frame easily. As shown in FIG. 2 and FIG. 3, the filter support device 1 bulges in the cross-sectional shape with the hinge portion as the top portion by folding the attachment portion 4 back to the back side (ventilation fan frame side) and temporarily fixing it. Both ends (attachment portions) have a structure that is bent inward. Such a structure differs from the device in which the mounting part is folded back to the surface side from the ventilation fan frame side, and has an arch shape that bulges outward from the bent part with the mounting part as the base, and external force (wind pressure, etc.) ) Acts on the support frame, the shape can be held firmly and the outwardly expanding force can be suppressed from acting on the mounting portion. Therefore, by folding the attachment portion inward or on the back side, the bent shape of the support frame can be maintained and the filter can be firmly supported.

  Both sides in the vertical direction of the planar support frame 2 are expanded in the lateral direction with the hinge 3 as the center, and both sides in the lateral direction of the planar support frame 2 (that is, the creases) rather than the length of the hinge 3. The longitudinal length of the line 4a) is formed large. That is, the planar support frame 2 has a symmetrical structure with the hinge portion 3 as a center line, and has two symmetrical trapezoidal shapes with the hinge portion 3 as a common upper base. The crease lines 5a that define both sides in the vertical direction of the planar support frame 2 are both descended toward the inside of the support frame 2 (in the direction of the hinge portion), and the crease line is formed at each side. The line 5a is formed in the shape of a “<” character (or V-shape). In this manner, the reinforcing support portions 5 formed on the both sides in the vertical direction are lowered by inclining and lowering the both sides in the vertical direction of the planar support frame body 2 toward the substantially central portion in the horizontal direction. It is a structure that can be easily folded inward (back side or ventilation fan frame side) with the body folded. Further, the reinforcing support portion 5 extends in the vertical direction with a predetermined width from both longitudinal sides of the planar support frame 2 via the crease line 5a.

  As described above, the reinforcing support part 5 is formed with a predetermined width on both sides in the longitudinal direction of the planar support frame. The width of the reinforcing support part 5 is temporarily fixed to the ventilation fan frame. What is necessary is just to be able to hold | maintain the space for ventilation | gas_flowing between the vertical direction both sides and a ventilation fan frame. The reinforcing support part 5 is bent to the back side (inner side or ventilation fan frame side) of the support frame body in a state where the flat support frame body is bent by the hinge part 3 via the crease line 5a. It has the role which reinforces the two vertical direction both sides.

  Inclined crease lines 5b are formed at both ends of the reinforcing support part 5, and triangular reinforcing parts 6 that can be bent along the crease lines are formed. Furthermore, a single crease line 5c extending in the vertical direction from the cutout portion 7 is formed in the reinforcing support portion 5.

  As shown in FIG. 4, the reinforcing portion 6 is also folded back to the ventilation fan frame side and attached to the attachment portion 4 so as to be positioned inside the attachment portion 4 in a bent state. When the reinforcing portion 6 is bent and attached, it becomes possible to reinforce the reinforcing support portion. As a result, both the longitudinal sides of the planar support frame 2 are reinforced, and the reinforcing support portion 5 is inwardly formed by the crease line 5c. Hold the bent state. In particular, it is possible to further reinforce both sides in the vertical direction by bending the reinforcing portion 6 to the inside of the attaching portion 4 and attaching the reinforcing portion 6 to the attaching portion 4 and integrally fixing them together. Moreover, since the reinforcement part 6 functions as a double reinforcement part for integrating the attachment part 4 and the reinforcement support part 5 by temporarily fixing in such a state, the shape retaining property of the support frame body Greatly increase. Therefore, the reinforcement part 6 contributes also to stabilization of the above-mentioned three-dimensional structure in the mounting state of the filter support device.

  In addition, since the notch part 7 also absorbs the deformation | transformation which arises with bending of the hinge part 3 and the reinforcement support part 5, the reinforcement support part 5 does not bend to the outer side (surface side) of the support frame 2, but the inner side (ventilation fan). It helps to keep the bent state on the frame side.

  Further, the planar support frame 2 has a ventilation portion 2 a formed in a region between the hinge portion 3, the attachment portion 4, and the reinforcement support portion 5. In other words, the planar support frame 2 is formed with a ventilation portion 2a leaving a plurality of support portions 2b connected to each other. This ventilation part 2a is formed as an opening part of a petal pattern, and can ventilate.

  The material of the ventilation fan filter support device is not particularly limited as long as it is a moldable material. For example, various plastics (for example, an olefin resin such as polypropylene, an acrylic resin such as polymethyl methacrylate, polyethylene terephthalate, etc. Polyester resin, polyamide resin such as nylon 6, polycarbonate, etc.), paper, wood, metal and the like can be used. Of these materials, plastics such as polypropylene and polyethylene terephthalate and paper are preferable from the viewpoint of moldability and workability. The parts constituting the ventilation fan filter support device may be the same material or different materials, but are usually the same material from the viewpoint of manufacturing cost.

  In the planar support frame, the structure of the hinge part is not limited to a double crease line as long as the support frame can be bent, and may be formed by a single crease line, for example. In addition to the crease line, a hinge structure such as a cut structure (for example, a cut depth of about 1/2 to 1/50, preferably about 1/5 to 1/20 with respect to the thickness of the support frame) or a hinge. It may be a structure or the like. Note that the fold line other than the hinge part is not limited to the fold line (crease line), and may have the same structure as the hinge part.

  The ventilation portion of the planar support frame is not particularly limited as long as an air permeable area is secured, and even if it has another pattern (for example, a pattern in which the support portion is formed in a lattice pattern or a perforated pattern). Good. The occupation area of the ventilation portion is 40% or more (for example, 40 to 99%), preferably 50 to 95%, more preferably about 60 to 90% with respect to the entire surface of the support frame.

  The both sides in the longitudinal direction of the planar support frame need not be inclined, and may be flat or parallel. Further, the both sides in the vertical direction form reinforcing support portions, and in order to reinforce the both sides in the vertical direction of the planar support frame body, the side portions extend from the hinge portion in the lateral direction and are longer than the length of the hinge portion. It is preferable to incline so that the length in the longitudinal direction of both sides in the direction increases. This inclination angle is, for example, about 5 to 60 °, preferably about 10 to 45 °, and more preferably about 15 to 40 °. The ratio of the longitudinal length of both sides in the horizontal direction of the planar support frame to the length of the hinge portion is the former / the latter = 3/1 to 1/1, preferably 2/1 to 1.2 / 1, It may be preferably about 1.7 / 1 to 1.3 / 1.

  The mounting portions need not be formed on the entire lateral sides on both lateral sides of the planar support frame (that is, formed as mounting sides extending with a predetermined width from both lateral sides). You may form in a part site | part (or partial) part. For example, one or a plurality of tongue-side extending attachment portions may be formed by partially extending laterally from both lateral sides of the planar support frame. Specifically, as shown in FIG. 5, a plurality of tongue-like extension mounting portions 24 may be formed on the left and right lateral sides. In particular, it is effective to form a double reinforcing structure in a region including at least both ends (corner portions) of both side portions in the lateral direction in combination with the point of support strength and the reinforcing portion. Among these, in order to maintain the bent shape and firmly support the filter, it is advantageous to form it as an attachment side.

  The length of the attachment portion can be selected according to the size of the ventilation fan to be attached, and from the point of reinforcing the ventilation fan filter support device, the larger the width, the more preferable. Usually, the length of the hinge portion is 1/2 to It may be about 1/20, preferably 1/3 to 1/15, more preferably about 1/4 to 1/10. The width of the mounting portion is not particularly limited as long as it has an area that can sufficiently contact the ventilation fan frame, but when forming the reinforcing portion, both end portions on both sides in the horizontal direction of the planar support frame are provided. In the including region, it is preferable that surface contact with the reinforcing portion (particularly, contact with the entire surface of the reinforcing portion) is possible. The shape of the attachment portion is not particularly limited, but is usually a quadrangular shape at least at both end portions on both sides in the lateral direction of the support frame. The temporary fixing method between the mounting part and the ventilation fan frame is not only a method using an adhesive such as a double-sided adhesive tape or a pressure sensitive adhesive, but also a method using a magnet, locking or engagement (a fine and a plurality of hook-like projections with a fibrous material A method based on a method of entanglement and fixing (including a so-called surface fastener) may be used.

  The reinforcing support part is not necessarily required, but it is preferable to provide the reinforcing support part over the entire area on both sides in the vertical direction of the planar support frame from the viewpoint of reinforcing both sides in the vertical direction of the planar support frame. The width of the reinforcing support part is, for example, about 1/3 to 1/30, preferably 1/4 to 1/20, and more preferably about 1/5 to 1/15 with respect to the length of the hinge part. The width of the reinforcing support portion does not need to be uniform (or the same), and may be non-uniform. However, from the point of forming the reinforcing portion, the reinforcing portion is provided at both ends of both sides in the longitudinal direction of the support frame. It is preferable that a width that can be formed is formed. Specifically, as shown in FIG. 6, the reinforcing support portion 25 is formed so that the width decreases from both ends of both sides in the vertical direction of the planar support frame body 22 toward the hinge portion 23. At the same time, reinforcing portions 26 may be formed at both ends of the reinforcing support portion 25.

  The shape of the reinforcing portion is not particularly limited, and may be a quadrilateral shape in addition to a triangular shape. The reinforcing portion may be temporarily fixed by directly contacting the ventilation fan frame, but it is effective to temporarily fix the reinforcing portion in combination with the mounting portion. In particular, since the attachment portion can contact the ventilation fan frame with a larger area, the attachment portion is preferably attached to attachment portions formed at both end portions on both sides in the lateral direction of the planar support frame. The size of the reinforcing portion is preferably larger from the viewpoint of reinforcement of the support frame (or the support device), but when temporarily fixed in combination with the mounting portion, it may be adapted to the size of the mounting portion.

  The notch portion (space portion) may be formed to such an extent that the strength of the reinforcing support portion is not impaired, and is usually provided at the intersection area between the hinge portion and the bending line of the reinforcing support portion. The notch is, for example, a size of 1/2 or less (for example, about 1/5 to 1/2, preferably about 1/4 to 1/2) with respect to the width of the reinforcing support, and is circular or elliptical. Alternatively, the shape may be a square shape.

  Such a ventilation fan filter support device can be manufactured by a conventional method. For example, in the case of a molded product formed of plastic or paper, it can be manufactured by punching or the like.

  As shown in FIG. 2, the ventilation fan filter support device 1 can be temporarily fixed to the ventilation fan frame 12 in a form bent at the hinge portion 3 as a boundary. The bending angle of the device 1 temporarily fixed to the ventilation fan frame 12 is not particularly limited as long as it can cover the ventilation fan, and is, for example, 30 to 150 °, preferably 40 to 130 °, more preferably about 50 to 120 °. It is.

  In the temporary fixing of the device 1 and the ventilation fan frame 12, as shown in FIG. 4, the attachment part 4 is folded back to the ventilation fan frame side, and the attachment part 4 and the ventilation fan frame 12 are temporarily fixed means (double-sided adhesive tape or the like). It is temporarily fixed by. Further, the reinforcing portion 6 is also folded back to the ventilation fan frame side so as to be positioned inside the attachment portion 4 and attached to the attachment portion 4 with a double-sided adhesive tape or the like.

  In this invention, a filter can be mounted | worn with a ventilation fan by combining such a ventilation fan support apparatus and the filter which a peripheral part can shrink | contract. As a filter, in addition to a filter whose peripheral part can contract, other filters may be used as long as the side part of the ventilation fan filter support device and the ventilation fan frame can be crowned. By combining, it becomes possible to attach the filter to the ventilation fan by a simpler method.

  Specifically, as shown in FIG. 3, a ventilation fan having a fan 13 and a ventilation fan frame 12 surrounding the fan is provided on a wall 14. Temporary fixing means 8 is provided on the ventilation fan frame 12 of the ventilation fan. The ventilation fan filter support device 1 is temporarily fixed through. The filter 10 covers the side portions of the device 1 and the ventilation fan frame 12. This filter 10 is a filter whose peripheral part can contract, and can cover a ventilation opening corresponding to a ventilation fan frame of various shapes.

  In addition to the filter body, the filter 10 has a stretchable string-like body 11 provided on the peripheral edge of the filter body. More specifically, the filter 10 is formed in a bag shape having an opening portion, with the peripheral portion bent inward over the entire circumference, leaving the central portion.

  Although the filter 10 should just be formed with the material which has air permeability, it is preferable that it is formed with the flame-retardant nonwoven fabric. Although the flame retardant nonwoven fabric can be formed of various materials, it is preferably formed of a flame retardant fiber in which polyvinyl chloride exists in a fibril form in a polyvinyl alcohol matrix and a reinforcing fiber such as a polyester fiber. The thickness of the fibers constituting the nonwoven fabric can be appropriately selected in consideration of the strength and breathability of the filter. The thickness of the fiber is, for example, about 2 to 20 denier, and is often 10 denier or less (for example, about 5 to 10 denier). The stretchable string may be made of a stretchable material such as synthetic rubber.

  By using such a filter, it is possible to easily attach the filter to the ventilation fan frame on which the apparatus is mounted by a simple operation of extending and releasing the stretchable string-like body 11. As such a filter, for example, a cover for a ventilation port described in JP-A-2002-361019 can be used.
