Description

Technical Field

[0001] The present invention relates to a filter fixture used when attaching a filter to a ventilation fan or an intake / exhaust port.

Background Art

[0002] In order to prevent ventilation fans and intake / exhaust ports installed in a room from getting dirty, it is common practice to attach a filter to their surfaces by appropriate means such as pasting. However, when such ventilation fans and intake / exhaust ports are located at a high place such as the ceiling of a room, the attachment work is difficult.

[0003] That is, for a person of short stature, it is not easy to reach the high place with their hand, and it is also dangerous to perform the work using a chair or the like as a stepping stool. Especially for the elderly, etc., it was difficult to perform the work of pressing the filter against a ventilation fan or the like with a certain force and attaching it without gaps in an unstable state of the scaffold.

[0004] Therefore, as in Patent Document 1, as a fixture for a filter with a frame, a hanging portion engageable with the frame is provided at the tip of a long handle, and by holding and operating this handle, a filter with a frame engaged with the filter hanging portion is brought close to the ventilation fan to perform the attachment work. Such a device has also been invented.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, such a filter attachment can only attach filters of the type with a frame attached, so it has poor versatility and cannot be used for filters without an attached frame. In particular, in recent years, many types of filters without an attached frame that can be attached by pressing against a ventilation fan or an air intake / exhaust port are widely used. In addition, it is necessary to fit the filter frame with the frame of a ventilation fan installed at a high place such as the ceiling, etc., and it is quite difficult to perform this remotely by operating the handle from the floor surface.

[0007] Therefore, an object of the present invention is to provide a filter attachment that can be used for the attachment work of all types of filters that can be attached by pressing against a ventilation fan or an air intake / exhaust port, and that can easily perform such work.

Means for Solving the Problem

[0008] In order to solve the above problems, the filter attachment according to the invention has a holding surface on its upper surface on which a filter that can be attached by pressing against a ventilation fan or an air intake / exhaust port can be placed, and a connecting portion on its lower surface to which a handle can be connected, and at least includes a head. Then, with the filter placed on the holding surface of the head and the handle connected to the connecting portion, the handle is grasped to operate the head, and the filter can be attached to the ventilation fan or the air intake / exhaust port by pressing the holding surface on which the filter is placed against the ventilation fan or the air intake / exhaust port.

[0009] With such a configuration, since the filter is placed and held on the holding surface of the head, it is possible to attach a filter of the type without a frame to a ventilation fan or an air intake / exhaust port at a high place. Also, when operating the handle from the floor surface, since the attachment of the filter is completed simply by pressing the holding surface of the head against the ventilation fan or the air intake / exhaust port installed on the ceiling, etc., the work is easy unlike the case of fitting the filter frame with the ventilation fan, etc.

[0010] In the filter fixture according to the invention, a configuration may be adopted in which a handle connected to the connecting portion of the head is further provided.

[0011] Here, the handle being connected to the connecting portion of the head includes not only a mode of connecting a separate handle and the head, but also a mode in which the handle and the head are connected in advance. In addition, it is assumed that not only a mode in which the handle and the head can be separated, but also a mode in which the handle and the head cannot be separated by integral molding or the like is included. Note that the head of the filter fixture can be circulated alone and connected to an existing handle at each household or the like, or can be circulated in a state of being set with the handle.

[0012] In the filter fixture according to the invention, it is preferable to adopt a configuration in which the head and the handle are detachable.

[0013] With such a configuration, when storing at home or displaying in a store, the head and the handle can be separated so as not to take up space. In addition, when the head is damaged, only the head can be replaced and the handle can be reused as it is.

[0014] In the filter fixture according to the invention, it is preferable to adopt a configuration in which the holding surface of the head is composed of a flat portion at the periphery that supports the filter and a central concave portion into which the protruding portion fits when the head is pressed against a ventilation fan or an intake / exhaust port protruding from the wall surface.

[0015] With such a configuration, it is possible to bring the head into close contact with a ventilation fan or an intake / exhaust port of a type protruding from the wall surface, and the filter can be attached without floating up from the ventilation fan or the like. Since the filter is supported by the flat portion of the holding surface, the filter can also be attached to a ventilation fan or an intake / exhaust port of a type that does not protrude from the wall surface (a type flush with the wall surface).

[0016] In the filter fixture according to the invention, it is preferable to adopt a configuration in which the head stands up from the outer edge of the holding surface and has a stopper for preventing the filter placed on the holding surface from slipping sideways.

[0017] Since the filter is only placed on the holding surface, it is likely to slip sideways during the installation work on the ventilation fan or the intake and exhaust port, and there is a risk of falling off the head. By adopting such a configuration with a stopper, the filter that is about to slip sideways hits the stopper and is prevented from slipping, so that it is prevented from falling off the head. Therefore, the filter installation work is carried out more reliably.

[0018] In the filter fixture according to the invention, it is preferable to adopt a configuration in which the head is bent outward at the tip of the stopper and continuously provided with a claw that can be hooked on the filter attached to the ventilation fan or the intake and exhaust port.

[0019] When the ventilation fan or the intake and exhaust port is at a high place such as the ceiling, not only the installation work of the filter but also the removal work becomes difficult. By adopting such a configuration with a claw, the handle can be operated from the floor surface, and the claw can be hooked on the filter and peeled off. Therefore, the filter removal work can be easily carried out.

[0020] In the filter fixture according to the invention, it is preferable to adopt a configuration in which the claw has a hook-and-loop fastener portion on its outer surface that can be entangled with the fibers of the filter.

[0021] With such a configuration, the claw is likely to be hooked on the filter due to the action of the hook-and-loop fastener portion, so that the filter can be easily peeled off from the ventilation fan or the intake and exhaust port, and the filter removal work can be carried out more easily.

[0022] In the filter fixture according to the invention, it is preferable to adopt a configuration in which the head has a triangular rib between the stopper and the claw.

[0023] With such a configuration, the rib reinforces the claw, preventing the claw from breaking or being damaged when hooking the claw on the filter. In addition, when the head is integrally molded, there is a risk that the claw may warp or fall over after molding (the bending angle with respect to the stopper may deform to an angle different from the intended angle) due to shrinkage of the material or the like. However, the shape-retaining action of the rib prevents the claw from warping or falling over in this way. Therefore, the claw can be maintained at an appropriate bending angle for the filter removal operation. Furthermore, when hooking and peeling off the claw from the filter, the hypotenuse of the triangular rib serves as a guide, directing the peeled portion of the filter downward, so that the filter removal operation can be performed smoothly.

Advantages of the Invention

[0024] Since the present invention is configured as described above, a filter attachment tool that can be used for the attachment operation of all types of filters that can be attached by pressing against a ventilation fan or an intake / exhaust port, and that can easily perform the operation, is provided.

Mode for Carrying Out the Invention

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The filter fixture 1 of the embodiment shown in FIGS. 1 and 2 is used when attaching the filter F of the type that can be attached by pressing against the ventilation fan V to the ventilation fan as shown in FIG. 3. By using the filter fixture 1 of the embodiment, when the ventilation fan V is installed at a high place such as the ceiling, the installation work becomes easy. Further, the filter fixture 1 of the embodiment is also used when removing the filter F from the ventilation fan V as shown in FIGS. 4 and 5, thereby facilitating the removal work.

[0027] As shown in FIG. 1, the filter fixture 1 of the embodiment includes a head 10 and a handle 20, and the head 10 and the handle 20 are connected via a joint 30.

[0028] As shown in FIGS. 1 and 2, the head 10 is generally square in plan view as a whole and is flat and substantially plate-shaped. The entire upper surface of the head 10 serves as a holding surface 11 on which the filter F can be placed, and a connecting portion 12 that can be connected to the handle 20 via the joint 30 is provided on the lower surface thereof.

[0029] The dimensions of the holding surface 11 are not particularly limited, but are preferably dimensions corresponding to the general dimensions of the filter F of the type attached to the ventilation fan V, and can be exemplified as being 150 to 250 mm square. If the holding surface 11 exceeds 250 mm, the head 10 becomes large and difficult to handle, and if it is less than 150 mm, it becomes difficult to place a filter F of general dimensions. Here, as the filter F, it is mainly assumed to be composed of a non-woven fabric made of synthetic resin fibers such as polyethylene terephthalate, with an adhesive process applied to one side, and capable of being attached to the surface of the ventilation fan V.

[0030] The holding surface 11 includes a flat portion 11a at the periphery and a concave portion 11b at the center. The flat part 11a is formed to be generally flat, and the filter F placed on the holding surface 11 seems to be supported here. The dimensions of the flat part 11a are not particularly limited as long as the filter F can be supported, but it can be exemplified that the width is 5 to 10 cm. Also, the recess 11b is recessed in a square shape toward the lower surface of the head 10. The boundary with the flat part 11a is a slope, and the bottom of the depression is a flat surface.

[0031] When the head 10 is brought close to the ventilation fan V and its holding surface 11 is pressed, the protruding portion from the wall surface of the ventilation fan V fits into the recess 11b, so that the holding surface 11 will be almost in close contact with the ventilation fan V. Therefore, the filter F placed on the holding surface 11 is almost completely attached to the surface of the ventilation fan V, and a situation where a part of it floats up from the ventilation fan V is prevented. Here, the depth of the recess 11b is not particularly limited, but as the depth corresponding to the protruding amount from the wall surface of a general ventilation fan V installed at a high place such as the ceiling, 3 to 10 mm can be exemplified, and 4 to 7 mm is preferable. When the depth of the recess 11b exceeds 10 mm, the thickness of the head 10 increases accordingly, making it larger and difficult to handle. When the depth is less than 3 mm, the protruding portion of the ventilation fan V cannot be absorbed, and it becomes difficult to make the holding surface 11 in close contact with the ventilation fan V.

[0032] As shown in FIGS. 1 and 2, rectangular stoppers 13 stand up from the left and right edges of the holding surface 11 respectively. In the illustration, the stoppers 13 are arranged in three rows along each of the left and right edges, and the stoppers 13 in each row face each other in the left - right direction. When the filter F placed on the holding surface 11 is about to shift horizontally during the installation work, it hits the stopper 13, so it is maintained in the original position, and a situation where the filter F falls from the head 10 is prevented.

[0033] The height of the stopper 13 is not particularly limited, but it is preferably the same as or smaller than the protruding amount from the wall surface of a general ventilation fan V, and is preferably 2 to 5 mm. If the height exceeds 5 mm, it is too high, and during the installation work of the filter F, the stopper 13 around the ventilation fan V may interfere with the wall surface, and there is a risk that the holding surface 11 cannot be sufficiently pressed against the ventilation fan V. If it is less than 2 mm, it is too low, and when the filter F slips laterally, it may overcome it, and there is a risk that the function of maintaining the position of the filter F cannot be exerted.

[0034] As shown in FIGS. 1 and 2, among the stoppers 13 on the left and right edges, claws 14 are respectively connected to each stopper 13 on one edge. The claw 14 bends substantially vertically from the tip of the stopper 13 and extends outward from above the holding surface 11. Also, as shown in the figure, a triangular rib 15 is spanned between the stopper 13 and the claw 14 to reinforce it. Here, the upper surface of the claw 14 is a small flat surface, and a male surface fastener of the male and female is attached here, thereby forming a surface fastener portion 14a. When removing the filter F attached to the ventilation fan V, this claw 14 is used. As will be described later, the claw 14 is hooked on a portion (hooking portion) where no adhesion process is performed with a width of about 5 mm from the edge of the filter F, and the peeling operation is performed.

[0035] As shown in FIGS. 1 and 2, a connecting portion 12 is provided at the center of the lower surface of the head 10. The inside of the connecting portion 12 is a through hole 12a of a circular hole penetrating to the upper surface of the head 10, and a cylindrical flange 12b is provided at the hole edge.

[0036] The material of the head 10 is not particularly limited, and examples include synthetic resin and metal. As a material that is lightweight, difficult to deform, and difficult to break, it can be exemplified by a hard synthetic resin such as ABS (acrylonitrile-butadiene-styrene copolymer). Also, the manufacturing mode of the head 10 is not particularly limited, and it can be manufactured by separately manufacturing the main body, the stopper 13, the claw 14, etc. and then joining them. However, integral molding of the whole is preferable because the manufacturing is easy. In the case of integral molding, even when the material shrinks, due to the presence of the triangular rib 15, the bending angle of the claw 14 with respect to the stopper 13 is maintained, preventing the claw 14 from warping or falling in an unintended direction after molding. The surface property of the head 10 is not particularly limited, but it may be subjected to fine unevenness processing such as fine embossing. The embossing processing makes it more difficult for the filter to shift from the holding surface 11 of the head.

[0037] As shown in FIG. 1, the handle 20 is a long rod-shaped object and is connected to the connecting portion 12 of the head 10 via the joint 30. The handle 20 may be hollow or solid, and its length is not particularly limited. However, when holding and operating it, it is preferably long enough for the head 10 to reach a ventilation fan installed on the ceiling of the room, and it can be exemplified as 60 to 120 cm. The material of the handle 20 is not particularly limited either, and examples include synthetic resin, metal, and wood. However, as a lightweight, difficult-to-deform, and difficult-to-break material, it can be exemplified as being made of a hard synthetic resin such as ABS. Such a handle 20 can utilize an existing rod-shaped object.

[0038] As shown in FIG. 1, the joint 30 has a cylindrical shape with a closed upper end, and longitudinal ribs 31 are provided in parallel in the circumferential direction on the outer periphery near this upper end. The upper end of the joint 30 is inserted into the connecting portion 12 of the head 10, and the upper end of the handle 20 is inserted into the open lower end of the joint 30, whereby the head 10 and the handle 20 are connected via the joint 30. Here, the longitudinal rib 31 adjusts the fitting strength between the head 10 and the joint 30. The material of the joint 30 is not particularly limited, and an example is synthetic resin. However, as an elastically deformable material capable of corresponding to handles 20 having a plurality of diameters, it is preferably made of a soft synthetic resin such as an elastomer.

[0039] The configuration of the filter fixture 1 of the embodiment is as described above. Next, its usage method will be described.

[0040] First, when attaching the filter F to the ventilation fan V, as shown in Fig. 3(a), with the holding surface 11 of the head 10 facing upward, place the filter F here with the surface subjected to the adhesion process facing upward. Then, as shown in Fig. 3(b), hold and operate the handle 20, and while maintaining the orientation of the head 10, lift it high and approach the ventilation fan V installed on the ceiling, and press the holding surface 11 on which the filter F is placed against the ventilation fan V.

[0041] In the illustration, the ventilation fan V protrudes slightly from the ceiling wall surface. However, since a recess 11b is provided at the center of the holding surface 11, the protruding portion fits into or follows along this recess 11b, enabling the holding surface 11 and the surface of the ventilation fan V to be in close contact. If the protruding portion is larger than the recess 11b, it can be made to adhere to the surface of the ventilation fan V by the flat portion 11a even if the protruding portion does not fit into the recess 11b. When the holding surface 11 is pressed against the ventilation fan V, the filter F adheres to the surface of the ventilation fan V due to the action of the surface subjected to the adhesion process. Here, if the adhesion is not sufficient, the head 10 is tilted slightly and the filter F is pressed against the lifted portion of the filter F from the ventilation fan V, etc., to assist the pressing operation of the filter F by the head 10. When such a remote attachment operation of the filter F is completed, the handle 20 is operated to lower the head 10. When a new filter F is placed on the holding surface 11, the attachment operation of the filter F can be performed again.

[0042] Also, when removing the filter F from the ventilation fan V, hold and operate the handle 20, lift the head 10 high and approach the ventilation fan V installed on the ceiling with the filter F attached. Then, as shown in Fig. 4, insert the claw 14 of the head 10 between the non - adhesion - processed portion with a width of about 5 mm from the peripheral edge of the filter F and the surface of the ventilation fan V.

[0043] Then, as shown in Fig. 5(a), due to the action of the triangular rib 15, the peripheral edge of the filter F turns up and is guided downward, and the fibers at this peripheral edge are entangled with the hook-and-loop fastener portion 14a of the claw 14, so that the filter F is captured by the claw 14. If the head 10 is moved as it is from Fig. 5(b) to (c), the filter F is detached from the ventilation fan V, and the remote removal operation is completed. When the handle 20 is operated to lower the head 10 and the filter F is peeled off from the claw 14, it becomes possible to perform the removal operation of the filter F again.

[0044] When the work is completed, the joint 30 is removed from the connecting portion 12 of the head 10, the joint 30 is removed from the tip of the handle 20, the filter fixture 1 is disassembled, and it is stored in a non-bulky state for storage etc.

[0045] The embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present invention is shown by the claims, and includes all modifications and changes within the scope and in the equivalent meaning thereof.

[0046] For example, in the embodiment, as an example of the use of the filter fixture 1, the attachment of the filter F to the ventilation fan V is mentioned, but it is not limited to this, and it can also be used for the attachment of the filter F to all intake and exhaust ports including intake ports, exhaust ports, ventilation ports, etc.

[0047] Also, in the embodiment, as the filter F, a filter F with an adhesive process on one side is exemplified, but as long as it can be attached by pressing against a ventilation fan or the like, the type of filter is not limited to this. For example, a filter attached using the engaging force of a hook-and-loop fastener or the attracting force of a magnet may be used. In addition, in the embodiment, a portion (hooking portion) where no adhesion process is performed is provided with a width of about 5 mm from the peripheral edge of the filter F. However, this width is not limited to 5 mm and may be set in the range of 1 mm to 10 mm, more preferably in the range of 3 mm to 7 mm. Also, the portion where no adhesion process is performed may be located on the entire circumference or a part of the peripheral edge of the filter F. Also, the portion where no adhesion process is performed may not be provided. In this case, if the claw 14 of the filter fixture 1 is provided with a hook-and-loop fastener portion 14a, when removing the filter F from the ventilation fan V, by pressing the hook-and-loop fastener portion 14a of the claw 14 of the filter fixture 1 from below the filter F, the fibers of the filter F and the hooks of the hook-and-loop fastener portion 14a are intertwined, and by pulling the filter fixture 1 downward, the filter F can be removed while the fibers of the filter F and the hooks of the hook-and-loop fastener portion 14a are intertwined. The same removal method can also be adopted even when a hooking portion is formed on the filter F.

[0048] In the embodiment, the overall shape of the head 10 is square in plan view. However, the shape is not limited to this as long as the filter F can be placed on the holding surface 11 and attached to a ventilation fan or the like. For example, it can be circular or rectangular in plan view. In the embodiment, the entire upper surface of the head 10 is used as the holding surface 11. However, it is not limited to this, and a part of the upper surface of the head 10 may be used as the holding surface 11, such that the overall shape of the head 10 is circular in plan view and the shape of the holding surface 11 is square. Also, the shape of the holding surface 11 is not limited to the square shape of the embodiment. When the ventilation fan V is circular and a circular filter F is to be attached thereto, a circular holding surface can be provided accordingly. The shape of the concave portion 11b of the holding surface 11 is not limited to the square shape of the embodiment. When the ventilation fan V is circular as described above and a circular filter F is to be attached thereto, a circular depression in plan view can be provided accordingly. In the case of a type where the ventilation fan or the like does not protrude from the wall surface, the concave portion 11b of the holding surface 11 can be omitted and the whole can be made into a flat portion 11a.

[0049] In the embodiment, the stoppers 13 of the head 10 are arranged in three rows on the left and right, but it is not limited to this. The number can be reduced to two rows or a single row, or increased to four rows or more. Also, a wide stopper 13 can be provided on the entire side surface of the holding surface 11. In the embodiment, the stoppers 13 are provided on both sides of the left and right edges of the head 10, but it can also be provided on only one side. The shape of the stopper 13 is not limited to the embodiment, and it may be long and continuous along the left and right edges of the head 10. Also, it may protrude in a semicircular or triangular shape. When the holding force of the filter F is sufficient, such as when the friction coefficient of the holding surface 11 is high, the stopper 13 can be omitted.

[0050] In the embodiment, the claws 14 are continuously provided only on the stoppers 13 on one side of the left and right edges of the head 10, but the claws 14 can also be continuously provided on the stoppers 13 on both sides. Also, among the three rows of stoppers 13, the claws 14 can be continuously provided only on some of the stoppers 13. In the embodiment, the claws 14 are continuously provided on the stoppers 13, but the claws 14 can be provided at locations different from the stoppers 13, such as the claws 14 and the stoppers 13 being alternately arranged in parallel along the left and right edges of the head 10. In the embodiment, the bending angle of the claw 14 with respect to the stopper 13 is about 90 degrees, but the bending angle is not limited to this. Also, when the filter F is likely to be peeled off from the ventilation fan V due to the properties of the filter itself to be used or the surface properties of the ventilation fan or the like, the claws 14 can be omitted, or when it is not necessary to reinforce the claws 14 due to the material or the like, the triangular ribs 15 can be omitted.

[0051] In the embodiment, the surface fastener portion 14a is attached to the claw 14, but when the force of the claw 14 itself to peel off or capture the filter F is sufficient, the surface fastener portion 14a can be omitted. In the embodiment, a commercially available male hook-and-loop fastener is used as the hook-and-loop fastener portion 14a, but the present invention is not limited to this, and those having an action of entangling with the filter equivalently to this are also included in the hook-and-loop fastener portion referred to herein. In the embodiment, the hook-and-loop fastener portion 14a is provided on the upper surface of the claw 14, but the position and range of the hook-and-loop fastener portion 14a are not limited to this, and it can also be provided on the entire circumference of the claw 14 or at the tip of the claw 14.

[0052] In the embodiment, the head 10 and the handle 20 are connected via the joint 30, but they can also be directly connected. Further, the connection mode between the head 10 and the handle 20 and the configuration of the connection portion 12 are not limited to the embodiment, and for example, they can be connected by a hinge or fixed by appropriate means such as screwing and adhesion. The head 10 and the handle 20 can also be integrally formed. The shape of the handle 20 is not limited to the embodiment, and it may be in the shape of a handle.
