Description

  The present invention relates to a filter mounting structure for mounting an air filter to a filter casing in air conditioning equipment such as building air conditioning, factory air conditioning, and hospital air conditioning.

  Air filters such as building air conditioners, factory air conditioners, and hospital air conditioners use air filters to remove dust in the outside air. When such air filters become clogged and pressure loss increases, new air filters are used. The filter casing is detachably attached so that it can be replaced with a filter. Conventionally, there is a problem that this mounting work is complicated and requires a long time. As a solution to this problem, for example, an air filter mounting member disclosed in Patent Document 1 is known.

  As shown in FIG. 9, the air filter mounting member is provided with a filter press member 130 having a slide hole 131 in a direction substantially the same as the filter press direction between the filter press member 110 and the base member 120. The shaft 121 is integrated by penetrating into the slide hole 131. When the filter pressing member 110 is moved in the directions of arrows (b) and (c) by the screw mechanism, the filter pressing member 130 is also moved in the direction of the arrow. It moves in the direction of (c), and the filter is fastened and fixed.

  However, in such an air filter mounting member, the filter pressing member 110 is moved in the directions of arrows (b) and (c) by the screw mechanism, so that the screw mechanism itself is also moved in the direction of (c). Will do. Specifically, when the head of the bolt that has penetrated into the elongated hole 122 opened at the end of the base material 120 is rotated using a spanner or the like, the bolt head is pressed against the elongated hole along the elongated hole ( It will move in the direction of c). For this reason, there was a problem that it was difficult to operate.

  Hereinafter, embodiments of a filter mounting structure according to the present invention will be described in detail.

  The filter mounting structure 30 of the present invention is a filter mounting structure 30 for pressing and mounting the filter 10 against the filter casing 20 as illustrated in FIGS. 1 to 3, and includes a slide body 40 and the slide body. The slide body 40 includes a fixing member 50 that regulates the slidable member 40, a filter pressing member 70, a connecting member 60 that connects the slide body 40, the fixing member 50, and the filter pressing member 70 in this order. Is provided with a first long hole 41 whose longitudinal direction is oblique to the pressing direction of the filter, and the fixing member 50 has a second long hole whose longitudinal direction is the pressing direction of the filter. 51, the connecting member 60 is inserted into the first long hole 41 and the second long hole 51, and the filter pressing member 70. The filter pressing member 70 is slid while being regulated by the fixing member 50 so that the filter pressing member 70 is in the direction of the air inflow side or the air outflow side of the filter casing 20 (in FIG. The filter 10 can be pressed against the filter casing 20 by moving in the direction of the inflow side. Here, “the air inflow side or air outflow side of the filter casing 20” means “the air inflow side or the air outflow side of the filter casing 20” in the portion where the filter 10 is pressed against the filter casing 20. . Therefore, for example, in FIG. 1, the filter casing is also extended in front of the filter casing, and when air is taken in from above the extended portion, the air intake is not meant.

  The filter casing 20 is installed in an air conditioner as a structure formed by assembling a frame in a direction crossing the air flow direction so that the filter 10 can be pressed and attached as illustrated in FIG. is set up. In the present invention, the direction in which the filter 10 is pressed can be the same direction as the air flow, or the opposite direction. Therefore, when the direction in which the filter 10 is pressed is the same direction as the air flow, the filter pressing member 70 moves in the direction of the air outflow side of the filter casing 20, and the direction in which the filter 10 is pressed is the air flow. In the opposite direction, the filter pressing member 70 moves in the direction of the air inflow side of the filter casing 20. In the example of FIG. 1, the filter 10 is pressed in a direction opposite to the air flow. In this case, maintenance is facilitated because dust does not adhere to each member constituting the filter mounting structure 30. There are advantages. Further, in FIG. 1, when the direction in which the filter 10 is pressed is the same direction as the air flow, there is no possibility that rust, wear powder, etc. generated from each member constituting the filter mounting structure 30 will flow downstream. It is suitable when using a medium-high performance filter.

  In FIG. 1, the filter casing 20 is formed by combining a channel material having a U-shaped cross section and a hollow steel frame. Moreover, as shown in FIG. 1, it is preferable that the filter casing 20 has the receiving plate 21 in the location where the filter 10 contacts, and the seal between the filter 10 and the filter casing 20 can be ensured.

  As the filter 10, for example, a plate-shaped air filter medium made of nonwoven fabric or the like is housed in the filter frame 11, or a sheet-like air filter medium made of nonwoven fabric or the like is bent at regular intervals. A filter element in which a pleated filter element is housed in a filter frame 11 is applied. In addition, it is preferable that the packing 12 is fixed to the surface of the filter frame 11 in contact with the filter casing 20, and the sealing between the filter 10 and the filter casing 20 can be ensured by the fixing of the packing 12. Although the packing can be fixed to the filter casing 20 side, it is necessary to replace the packing due to the wear of the packing.

  In the example of FIG. 1, the filter 10 is inserted from the side of the filter casing 20 in a state where three are connected to the upper stage of the filter casing 20 and three are connected to the lower stage. The filter 10 is connected in a socket shape so that the left and right sides of the filter frame 11 can be connected to each other. When the filter 10 is installed, it can be easily connected by pointing the male mold of one socket into the other female mold. It has become.

  As illustrated in FIG. 3, the filter mounting structure of the present invention includes a slide body 40, a fixing member 50, a filter pressing member 70, the slide body 40, the fixing member 50, and the filter pressing member 70. The connecting member 60 is connected in this order.

  The slide body 40 includes a first long hole 41 whose longitudinal direction is an oblique direction with respect to the pressing direction of the filter, and as long as the slide body 40 can slide while being regulated by the fixing member 50, Is not particularly limited. For example, as shown in FIG. 3, it may be a cylindrical shape made of a hollow quadrangular prism, a hollow polygonal column, a solid polygonal column, or a channel shape having a U-shaped cross section. It is also possible to be a member. Moreover, as long as airtightness is maintained so that air does not flow from the upstream side to the downstream side, a structure in which a hole is formed in any surface of the slide body 40 is possible. The slide body 40 needs to include a first long hole 41 whose longitudinal direction is an oblique direction with respect to the pressing direction of the filter. The angle α formed between the longitudinal direction of the first long hole 41 and the pressing direction of the filter may theoretically be more than 0 ° and less than 90 °, but in practice, the moving distance of the slide body 40, the filter pressing From the relationship with the moving distance of the member 70, etc., it is preferably in the range of 60 degrees to 85 degrees, and more preferably in the range of 65 degrees to 75 degrees. When the moving distance of the slide body 40 is constant, the moving distance of the filter pressing member 70 is shorter as the angle α is larger, and the force required to move the filter pressing member 70 is smaller.

  The fixing member 50 includes a second long hole 51 whose longitudinal direction is the direction in which the filter is pressed. The shape of the fixing member 50 is not particularly limited as long as the slide body 40 is slidably regulated. 3 is a hollow quadrangular column that can accommodate the slide body 40, and is also a channel-shaped member having a U-shaped cross section, and a guide plate for preventing displacement is provided in a part of the opening. It is also possible that the portion is cylindrical. Further, as long as airtightness is maintained so that air does not flow from the upstream side to the downstream side, a structure in which a hole is formed in an arbitrary surface of the fixing member 50 is possible. In addition, as shown in FIG. 3, in the case of a hollow quadrangular prism, it is possible to provide the second long holes 51 on the upper surface and the lower surface and arrange the filter pressing member 70. Therefore, as shown in FIG. 1, when the filter 10 is attached to the upper and lower stages of the filter casing 20, the lower part of the filter 10 attached to the upper part of the filter casing 20, and the upper part of the filter 10 attached to the lower part of the filter casing 20 Are simultaneously moved in the direction of the filter casing, so that the upper and lower filters 10 can be attached to the filter casing 20, and there is an advantage that the operation is not troublesome and the number of parts can be reduced. Further, when fixing the fixing member 50 of the form shown in FIG. 1 to the receiving plate 21 of the filter casing 20, the flat plate portion in contact with the receiving plate 21 at one end of the fixing member 50 is attached to one end of the receiving plate 21. The flat plate portion in contact with the receiving plate 21 at the other end of the fixing member 50 is connected to the other end of the receiving plate 21 with a bolt, a rivet or the like. If fixed, it is possible to easily fix the fixing member 50 to the filter casing 20 with one touch without using welding.

  The fixing member 50 needs to include a second long hole 51 whose longitudinal direction is the direction in which the filter is pressed. It is preferable that the longitudinal direction of the second long hole 51 coincides with the pressing direction of the filter. If they do not match, the filter pressing member 70 arranged on the surface of the fixing member 50 moves in the direction in which the filter is pressed and simultaneously moves in a direction perpendicular to the direction in which the filter is pressed. It may not be possible to secure the seal. For this reason, the angle β formed by the longitudinal direction of the second long hole 51 and the pressing direction of the filter is preferably 0 ° to 5 °, and most preferably 0 °.

  As the filter pressing member 70, the slide body 40, the fixing member 50, and the filter pressing member 70 are disposed adjacent to the fixing member 50 in this order, and move in the direction of the filter casing, so that the filter 10 is moved to the filter casing 20. The shape is not particularly limited as long as the structure can be pressed against the rail. For example, as shown in FIG. 3, a flat plate-like member that can slide on the surface of the fixing member 50 and a rail 71 having a U-shaped cross section is provided. It is possible that In FIG. 3, after the filter 10 is slid from the side of the filter casing 20 by the rail 71 and the filter 10 is stored in the rail 71, the filter 10 can be pressed against the filter casing 20.

  For example, as illustrated in FIG. 6, when the filter 10 is a filter having a long depth, that is, a filter having a long distance from the air inlet to the outlet, a rail 72 having an L-shaped cross section is provided on the filter pressing member 70. It is also possible to adopt a structure in which the filter 10 is moved in the direction of the filter casing and pressed against the filter casing 20 by placing the raised portion of the rail 72 having an L-shaped cross section on the lower corner on the outlet side of the filter. Is possible. In FIG. 6, the lower side on the inlet side of the filter 10 is supported by a support member 22 attached to a receiving plate 21 provided in the filter casing 20. Further, the support member 22 is provided with wheels 23, and the fixing member 50 is also provided with wheels 24. The wheels 10 are slid along the rails 72 from the side of the filter casing and stored in a predetermined position. After that, the filter casing 20 is attached.

  As the connecting member 60, the slide body 40, the fixing member 50 and the filter pressing member 70 are connected in this order, and the first long hole 41 of the slide body 40 and the second long hole 51 of the fixing member 50 are connected. The shape of the slide body 40 is not particularly limited as long as the slide body 40 is inserted into the filter pressing member 70 and fixed to the filter pressing member 70. For example, the slide body 40 has a structure including long bolts 61, washers 62, 63, and nuts 64 as shown in FIG. The fixing member 50 and the filter pressing member 70 can be connected in this order and can be fixed to the filter pressing member 70. In the present invention, the slide body 40, the fixing member 50, and the filter pressing member 70 are connected in this order. Of course, the filter pressing member 70, the fixing member 50, and the slide body 40 are connected in this order. It is also possible.

  In FIG. 3, the slide body 40 and the fixing member 50 have a cylindrical shape composed of hollow quadrangular prisms having an upper surface and a lower surface, and first elongated holes 41 having the same shape are formed at the same positions on the upper surface and the lower surface of the slide body 40, respectively. The second elongated holes 51 having the same shape are provided at the same position on the upper surface and the lower surface of the fixing member 50, respectively, and the filter pressing member 70 is slidable on the upper surface and the lower surface of the fixing member 50, respectively. The filter pressing member 70 is provided with a round hole 72 through which the long bolt 61 passes. Here, the long bolt 61 includes the washer 62, the round hole 72 of the filter pressing member 70, the second long hole 51 on the upper surface of the fixing member 50, the long hole 41 on the upper surface of the slide body 40, and the length of the lower surface of the slide body 40. The hole 41, the second long hole 51 on the lower surface of the fixing member 50, the round hole 72 of the filter pressing member 70, and the washer 63 are passed through in this order, and then the nut 64 is screwed to connect these members and filter pressing member The long bolt 61 can be fixed to 70.

  In FIG. 1, the filter mounting structure 30 provided in the center has the form shown in FIG. 3, and the filter mounting structure 30 provided in the upper part has a filter pressing member 70 disposed on the upper surface of the fixing member 50. The filter pressing member 70 is disposed only on the lower surface of the fixing member 50. Further, in the filter mounting structure 30 provided in the lower part, the filter pressing member 70 is not disposed on the lower surface of the fixing member 50, and the filter pressing member 70 is disposed only on the upper surface of the fixing member 50.

  As the connecting member 60, a rivet (not shown) can be used instead of the long bolt 61 described above. In this case, the shaft of the rivet is fitted into the round hole 72 of the filter pressing member 70. There is no need to fasten and fix the filter pressing member 70 on the upper surface. Therefore, there is an advantage that the filter pressing member 70 can easily slide on the upper surface of the fixing member 50. Further, since the rivet head is low in height, it is possible to arrange the rail 71 on the rivet head. In this case, the slide body 40, the fixing member 50, and the filter pressing member 70 are made compact. There are advantages that can be done. In order to arrange the rail 71 on the rivet head, a thin plate having a thickness corresponding to the height of the rivet head is prepared, and a hole is made in a portion where the rivet head hits the thin plate. Therefore, it is desirable to interpose this thin plate between the filter pressing member 70 and the filter pressing member 70.

  In the present invention, by assembling the members described above, the slide body 40 is slid while being regulated by the fixing member 50, so that the filter pressing member 70 moves in the direction of the filter casing, and the filter 10 is moved to the filter casing 20. It can be pressed. In FIG. 3, the moving direction of each member is indicated by an arrow on the right side of the assembly drawing, and the filter pressing member 70 moves in the direction of the filter casing by moving each member in the direction of row (a). Thus, the filter 10 can be pressed against the filter casing 20. Further, when each member moves in the direction of the row (B), the filter pressing member 70 moves in the direction opposite to the filter casing direction, and the filter 10 pressed against the filter casing 20 is pulled away from the filter casing 20. Can do. Alternatively, the filter 10 pressed against the filter casing 20 can be released from the pressed state.

  The case where each member moves in the direction of row (a) in FIG. 3 will be described. A cylindrical slide body 40 made of a hollow quadrangular column is placed in a cylindrical fixing member 50 made of a hollow quadrangular column. When it slides to the left so as to be pushed into the fixing member 50, the long bolt 61 moves forward along the first long hole 41 of the slide body 40 and the second long hole of the fixing member 50. Accordingly, the filter pressing member 70, the rail 71, and the filter 10 fixed to the long bolt 61 also move forward. Next, when each member moves in the direction of the row (B) opposite to the direction of the row (A), the cylindrical slide body 40 composed of a hollow quadrangular column is moved from the hollow quadrangular column. When it slides to the right side so that it pulls out from the fixing member 50 in the cylindrical fixing member 50 to be formed, the long bolts extend along the first long hole 41 of the slide body 40 and the second long hole of the fixing member 50. 61 moves backward, and along with this movement, the filter pressing member 70, the rail 71, and the filter 10 fixed to the long bolt 61 also move backward.

  In FIG. 3, the first elongated hole 41 of the slide body 40 has a longitudinal direction that is oblique to the direction in which the filter is pressed. As the oblique direction, the right side is the front and the left side is the rear. It is like that. On the other hand, by arranging the first elongated hole 41 so that the left side is the front and the right side is the rear as this oblique direction, the slide body 40 is pulled out from the fixing member 50 to the right side. When sliding, the filter 10 moves forward, and when the slide body 40 is pushed into the fixing member 50 and slid leftward, the filter 10 can be set to move backward.

  Here, in order to compare the present invention with the prior art disclosed in Patent Document 1, the slide body 40 of the present invention is used as the filter pressing member 110 of the air filter mounting member, the fixing member 50 is used as the base member 120, and the filter pressing member. When 70 is associated with the filter retainer 130 and the connecting member 60 is associated with the fixed shaft 121, the slide body 40 and the filter retainer 110 have a longitudinal direction that is oblique to the direction in which the filter is pressed. This is common in that the first long hole 41 or the inclined slide hole 111 is provided. However, in the present invention, the fixing member 50 is provided with the second elongated holes 51 whose longitudinal direction is the pressing direction, and the connecting member 60 moves along these elongated holes, so that the fixing member 50 is fixed to the connecting member 60. In contrast, the filter pressing member 70 has a mechanism that moves, whereas the filter pressing member 130 is provided with a slide hole 131 whose pressing direction is the longitudinal direction in the conventional technology, and is provided in the base material 120. Since the fixed shaft 121 is inserted into these holes, the filter pressing member 110 and the filter pressing member 130 move along the fixed shaft 121 while the fixed shaft 121 remains fixed. As described above, in the prior art, since the fixed shaft 121 is fixed, it is necessary to move the filter pressing member 110 back and forth and right and left to move the filter pressing member 130 back and forth, which makes it difficult to operate. . However, in the present invention, by allowing the connecting member 60 itself to move, the filter pressing member 70 can be moved back and forth simply by sliding the slide body 40 in one direction while being regulated by the fixing member 50, and therefore. The filter mounting operation has become easier.

  In the present invention, when the filter is pressed against the filter casing and attached, the filter pressing member 70 can be moved back and forth simply by sliding the slide body 40 in one direction while being regulated by the fixing member 50 as described above. The filter mounting operation is easy. For example, the rotation member 80 shown in FIGS. 2, 4 and 5 and the fastener member 90 shown in FIGS. 7 and 8 as described later are connected to or attached to the slide body 40, so that the operation can be performed with one touch. Compared with the case where the nut 114 is screwed into the long bolt 112 until it reaches a predetermined rotation as described above, there is an advantage that the labor of the mounting work can be greatly reduced. When connecting a filter with a small depth, such as a coarse dust filter or a pre-filter, as shown in FIG. 3, it is possible to provide a rail 71 having a U-shaped cross section on the filter pressing member 70. There is an advantage that the filter 10 connected to 71 can be accommodated and stored, and the filter 10 can be pressed and attached to the filter casing 20 while applying a load uniformly to the connected filter 10. As described above, when the filter 10 is attached to both the upper and lower stages of the filter casing 20 as shown in FIG. 1, the filter 10 is attached to the lower part of the filter casing 20 and the lower part of the filter casing 20. By moving the upper part of the filter 10 toward the filter casing at the same time, the upper and lower filters 10 can be attached to the filter casing 20, and there is an advantage that the operation is not troublesome and the number of parts can be reduced. is there.

  As described above, the filter mounting structure of the present invention can move the filter pressing member 70 back and forth simply by sliding the slide body 40 in one direction while restricting the slide body 40 by the fixing member 50. By combining the rotating member, the filter mounting operation can be further facilitated. As such a structure, for example, a rotating member that rotates around a fulcrum provided outside the slide body 40, and a second connecting member that connects the end of the slide body and the rotating member are provided. When the rotating member is rotated, the slide body 40 is slid while being regulated by the fixing member 50, and the filter pressing member 70 moves in the direction of the filter casing along with the sliding, so that the filter 10 is moved to the filter casing 20. And a filter mounting structure that can be pressed against. As a specific form, the filter attachment structure 30 provided with the rotating member 80 shown in FIGS. 2, 4 and 5 and the filter attachment structure 31 attached with the fastener member 90 shown in FIGS. . The rotating member means a member that rotates within an angle range of 360 degrees or less with the fulcrum as an axis, and is a member that rotates within an angle range exceeding 360 degrees, that is, rotates at a rotational speed exceeding one rotation. It is different from the rotating member. In the case of the filter mounting structure 30 shown in FIG. 2, the rotation angle of the rotation member is preferably 120 degrees or less. In the case of the filter mounting structure 31 shown in FIG. 7, the rotation angle of the rotation member is preferably 200 degrees or less although it depends on the position of the fulcrum.

  FIG. 2 is a cross-sectional view of the filter mounting structure 30 shown in the central portion of FIG. 1, (a) is a cross-sectional view and a vertical cross-section of the filter 10 pressed against the filter casing 20, and (b) These are figures which show the cross section and longitudinal section of the state which pulled apart the filter 10 from the state pressed on the filter casing 20, and were open | released. In the filter mounting structure 30 illustrated in FIG. 2A, as shown in FIG. 3, a slide body 40, a fixing member 50, a filter pressing member 70, and a connecting member 60 that connects these members are provided. Further, a rotating member 80 that rotates around a fulcrum 25 provided outside the slide body 40 as an axis, and a second connecting member 82 that connects the end 42 of the slide body 40 and the rotating member 80 are combined. It has. Then, the rotating member 80 rotates about the fulcrum 25 in the direction of the arrow in the drawing, so that the slide body 40 slides in the direction of pushing in as indicated by the arrow while being regulated by the fixing member 50. The pressing member 70 moves in the direction of the filter casing as indicated by an arrow, and the filter 10 can be pressed against the filter casing 20. In FIG. 2B, the rotating member 80 is rotated in the direction of the arrow in the drawing, so that the slide body 40 is slid in the pulling direction as indicated by the arrow while being regulated by the fixing member 50. Accordingly, the filter pressing member 70 moves in the direction indicated by the arrow, and the filter 10 can be pulled away from the state in which the filter 10 is pressed against the filter casing 20 to be opened.

  The rotation member 80 is not particularly limited as long as it is a member having a function of rotating around a fulcrum 25 provided outside the slide body 40, and the rotation member illustrated in FIG. 2 is taken as an example. Can be mentioned. In FIG. 2, the fulcrum 25 is provided on the side of the filter casing 20 so that the side can be rotated. Therefore, in FIG. 2, as shown in FIG. 1 and FIG. 4 of a partially enlarged view thereof, it can also be used as a door 81 that covers the side surface of the filter casing 20. 1-4, the filter 10 can be pressed against the filter casing 20 in conjunction with the operation of closing the door 81, and conversely, the filter 10 is pulled away from the filter casing 20 and opened in conjunction with the operation of opening the door 81. It is possible. The rotation member 80 may be a handle 83 that rotates about the shaft 25 as a rotation shaft, as illustrated in FIG. Further, the handle 83 can be interlocked with the door 81.

  In FIG. 2, the end portion 42 of the slide body 40 is made of a flat plate member, and projections 82 a and 82 b formed at one end portion of the rod-like second connecting member 82 pass through the flat plate member. The rotation member 80 is provided with a shaft portion 84 that pivotally supports the hole formed in the other end portion of the second connecting member 82. Specifically, the rod-like second connecting member 82 is formed of an eye bolt 82, and the protrusions 82a and 82b are formed of nuts 82a and 82b screwed into the eye bolt, and these nuts are spaced at a predetermined interval. Are arranged. A hole 43 is formed in the end portion 42 of the slide body 40, and after passing the threaded portion of the eyebolt through the hole 43, the hole 43 is disposed between the nuts 82a and 82b, and further, a rotating member. By inserting the rotation shaft 84 a of the shaft portion 84 of the 80 into the hole 82 c at the end portion of the eyebolt 82, the end portion 42 of the slide body 40 and the rotation member 80 are connected by the eyebolt 82.

  Therefore, as shown in FIG. 2A, when the rotating member 80 is rotated in the direction of the arrow in the drawing with the fulcrum 25 as an axis, the eyebolt 82 is moved to the rotating shaft 84a of the shaft portion 84 of the rotating member 80. With the hole 82c at the other end of the eyebolt 82 being pivotally supported, and the threaded portion of the eyebolt 82 is in a state where the movable range is restricted by the hole 43 at the end portion 42 of the slide body 40, the rotating shaft 84a is centered. As a result, the nut 82b of the eyebolt 82 pushes around the hole 43 of the end portion 42 of the slide body 40 in the direction of the arrow, and the slide body 40 also slides in the direction of the arrow. In FIG. 2B, when the rotation member 80 rotates about the fulcrum 25 in the direction of the arrow in the figure, the eyebolt 82 is attached to the rotation shaft 84 a of the shaft portion 84 of the rotation member 80. With the other end hole 82c being pivotally supported, and with the threaded portion of the eyebolt 82 being restricted in the movable range by the hole 43 in the end portion 42 of the slide body 40, the left direction about the rotation shaft 84a The nut 82a of the eyebolt 82 pulls around the hole 43 of the end portion 42 of the slide body 40 in the direction of the arrow, and the slide body 40 also slides in the direction of the arrow. Note that adjusting the slide distance of the slide body 40 to a predetermined length can be easily achieved by adjusting between the nuts 82a and 82b. Further, if necessary, the hole 43 of the end portion 42 of the slide body 40 is a long hole whose lateral direction is the longitudinal direction, so that it is possible to cope with the left and right fluctuations of the second connecting member 82. .

  In order to slide the slide body 40 in one direction while being regulated by the fixing member 50, in addition to the filter mounting structure 30 provided with the rotating member 80 described above, FIG. 7 is an assembly view of FIG. As illustrated in FIG. 8, the filter mounting structure 31 using the fastener member 90 as the rotating member can be illustrated. FIG. 7 shows a filter mounting structure 31 similar to that described in FIG. 3 in which a slide body 40, a fixing member 50, a filter pressing member 70, and a connecting member 60 for connecting these members are combined. Has been. In FIG. 7, the moving direction of each member is indicated by an arrow on the right side of the assembly drawing. As in FIG. 3, each member moves in the direction of row (a), so that the filter pressing member 70 is moved. Moving in the filter casing direction, the filter 10 can be pressed against the filter casing 20. Further, when each member moves in the direction of the row (B), the filter pressing member 70 moves in the direction opposite to the filter casing direction, and the filter 10 pressed against the filter casing 20 is pulled away from the filter casing 20. Can do. Alternatively, the filter 10 pressed against the filter casing 20 can be released from the pressed state. In FIG. 3, the end portion 42 of the slide body 40 is formed of a flat plate member. However, in FIG. 7, the flat member is not provided, and the side surface of the end portion 42 of the slide body 40 and the fixing member 50. 3 is different from FIG. 3 in that the fastener member 90 is disposed so as to connect the side surfaces of the end portion 52.

  8 is a partially enlarged view in which a part of the assembly diagram of FIG. 7 is enlarged, (a) is a perspective view of the slide body 40, (b) is a perspective view of the lower part of the fixing member 50, c) is an elevational view when the fastener member 90 is assembled, and (d) is a diagram of the slide body 40 and the fixing member 50 assembled. As shown in FIG. 8C, the fastener member 90 is configured such that a rotating member 91 rotates in the direction of an arrow about a fulcrum 94, and is connected to the rotating member 91 along with the rotation. The second connecting member 93 is moved so as to be attracted in the direction of the rotating member 91, and the hooking member 92 connected so as to be hooked to the distal end portion of the second connecting member 93 along with this movement. The collar portion 92a moves in the direction of the arrow. On the contrary, when the rotating member 91 rotates in the direction opposite to the direction of the arrow, the second connecting member 93 connected to the rotating member 91 is moved forward of the rotating member 91 along with the rotation. The stopper 92b of the latching member 92 connected to the tip of the second connecting member 93 is pushed in the direction opposite to the direction of the arrow. Moving.

  Here, the fulcrum 94, the turning member 91, and the second connecting member 93 of the fastener member 90 are provided on the side surface of the end portion 52 of the fixing member 50 as shown in FIG. The latch member 92 of the fastener member 90 is provided on the side surface of the end portion 42 of the slide body 40 as shown in FIG. The fixing member 50 has a notch in front of the rotating member 91, and is assembled so that a latching member 92 provided on the slide body 40 protrudes from the notch. Thus, as shown in FIG. 8D, when the slide body 40 is housed in the fixing member 50, the second connecting member 93 of the fixing member 50 protrudes from the notch. It is connected to the latching member 92.

  As a result, as shown in FIGS. 7 and 8, when the rotating member 91 is rotated in the direction of the arrow with the fulcrum 94 of the fastener member 90 provided on the side surface of the end portion 52 of the fixing member 50 as an axis, this rotation is performed. Along with the movement, the second connecting member 93 connected to the rotating member 91 moves so as to be attracted in the direction of the rotating member 91, and the second connecting member 93 is hooked on the distal end portion of the second connecting member 93 with this movement. Since the hook portion 92a of the latching member 92 provided on the side surface of the end portion 42 of the slide body 40 is moved in the direction of the arrow, the slide body 40 itself is also regulated by the fixing member 50. Move in the direction of the arrow. Thus, each member of the slide body 40, the filter pressing member 70, and the connecting member 60 that connects these members moves in the direction of the row (a), so that the filter pressing member 70 moves in the filter casing direction. Moving, the filter 10 can be pressed against the filter casing 20. On the contrary, when the rotating member 91 is rotated in the direction opposite to the direction of the arrow, the second connecting member 93 connected to the rotating member 91 is moved forward of the rotating member 91 along with the rotation. The stopper 92b of the latching member 92 provided on the side surface of the end 42 of the slide body 40 is connected to the tip of the second connecting member 93 along with the movement. Since it moves so as to be pushed in the direction opposite to the direction of the arrow, the slide body 40 itself moves in the direction away from the arrow while being regulated by the fixing member 50. In this way, each member of the slide body 40, the filter pressing member 70, and the connecting member 60 that connects these members moves in the direction of the row (B), so that the filter pressing member 70 is aligned with the filter casing direction. Moving in the opposite direction, the filter 10 pressed against the filter casing 20 can be pulled away from the filter casing 20. Alternatively, the filter 10 pressed against the filter casing 20 can be released from the pressed state.

  7 and 8, the rotating member 91 of the fastener member 90 is rotated from the side surface of the filter casing toward the back so that the slide body 40 is slid so as to be pushed into the fixing member 50. The filter mounting structure 31 that presses the filter 10 against the filter casing 20 has been described as an example. However, in order to facilitate comparison with the case where the rotating member 80 is applied, the slide body 40, the filter pressing member 70, and Each of the members of the connecting member 60 that connects these members is an example assembled so as to operate in the same direction as in the case of the rotating member 80. Actually, the rotating member 91 of the fastener member 90 is attached to the filter casing. It is considered that it is desirable to arrange it so that it is rotated from the side toward the front, which is easier to operate. For this purpose, the longitudinal direction of the first long hole 41 of the slide body 40 is set to be an oblique direction opposite to that in FIG. 7, and the filter 10 is pressed against the filter casing 20 by pulling the slide body 40 out of the fixing member 50. Is adopted.
