In the state where the filter 5 is set at the use position, the end of the filter 5 comes into contact with the protrusion 14 of the grill 10, so that the filter 5 is supported at a predetermined position and does not jump out of the filter support 20.

  Thereby, for example, in the door opening and closing type grill 10 provided on the ceiling or the like, even when the insertion port 30 of the filter 5 is directed downward when the grill 10 is opened, the filter 5 is attached to the filter support 20. Can be prevented from slipping off.

  Further, the stopper claw portion 41 on the back side of the engaging member 40 contacts the filter 5. That is, the engaging member 40 pushes the filter 5 toward the back surface of the grill 10. Thereby, the movement of the filter 5 can be suppressed and the filter 5 can be prevented from popping out. The engaging member 40 may be provided at a position that does not interfere with the filter 5.

  The grill assembly 4 includes an elastic body 31 serving as a biasing means between the grill 10 and the filter support 20. The elastic body 31 is, for example, a compression coil spring formed of a steel wire or the like, and a fixing tool 28 (for example, a rivet) provided on the filter support 20 and an elastic body support 33 (for example, provided on the grill 10). , Projections, etc.), both ends are supported by the filter support 20 and the grill 10, respectively. By providing the elastic body 31 serving as an urging means, the filter support 20 is urged in a direction away from the grill 10.

Pressed. Thereby, engagement with the engagement hole 24 and the engaging part 44 can be strengthened. The biasing means is not limited to a compression spring such as the elastic body 31, and may be a leaf spring, for example.

  Note that the edge 15 of the grill 10 extends to the back side so as to surround the periphery of the grill 10. A gap is formed between the inner surface 15a of the edge 15 and the filter support 20, but for example, the inner surface 15a of the edge 15 and the filter support 20 (for example, the side surface 26a of the filter support rail 26). Between them, a sliding material made of synthetic resin or the like may be provided. Thereby, the direct contact with the grill 10 and the filter support 20 can be prevented, and friction and wear can be suppressed.

  Further, in the case where a sliding member is provided, the inner surface 15a of the edge 15 of the grill 10 and the side surface 26a of the filter support rail 26 are brought into contact with each other, and the contact surface is actively used as a slidable guide surface. You may do it. Thereby, the contact surface provided with the sliding material can be used as a support means for supporting the filter support 20 so as to be separated from the grill 10.

  7A is a detailed view of a portion A of the grill assembly 4 shown in FIG. 2 and shows a state in which the filter support 20 is slid, and FIG. 7B is a view of FIG. It is the EE sectional view taken on the line shown to (A).

  As shown in FIGS. 7A and 7B, the filter support 20 is slid in the direction of removing the filter 5 so that the vicinity of the edge of the engagement hole 24 of the filter support rail 26 and the engagement member 40 The engagement portion 44 does not come into contact. That is, the engagement between the vicinity of the edge of the engagement hole 24 and the engagement portion 44 can be released.

  The engaging hole 24 is formed larger than the engaging portion 44 as described above. Thereby, the engaging part 44 can pass through the engaging hole 24. Therefore, when the engagement between the engagement hole 24 and the engagement portion 44 is disengaged, the filter support 20 can be moved away from the grill 10 (backward direction).

  Further, when the filter support 20 is slid, the edge portion of the engagement hole 24 on the opposite side of the insertion port 30 comes into contact with the flange portion 45 of the engagement member 40. Thereby, compared with the case where the flange part 45 is not formed, engagement with the engaging part 44 and the engaging hole 24 can be removed easily. That is, it is possible to prevent the vicinity of the edge portion of the engagement hole 24 on the opposite side of the insertion port 30 from entering the front surface side of the engagement portion 44, and the filter support 20 is caught by the engagement between the engagement hole 24 and the engagement portion 44. It is possible to suppress the pop-up from being inhibited.

  By sliding the filter support 20, the relative position of the fixture 28 and the elastic support 33 is changed as compared with the grill assembly 4 in the use state shown in FIG. 6, so that the elastic 31 is distorted. . In order to deal with this, for example, a configuration in which only one end of the elastic body 31 is fixed may be employed.

  FIG. 8A is a detailed view of a portion A shown in FIG. 2 of the grill assembly 4, showing a state where the filter support 20 is popped up from the grill 10, and FIG. 8B is a view showing the grill assembly 4. It is the FF sectional view taken on the line shown to FIG. 8 (A). 8A and 8B show the state of the grill assembly 4 when the filter 5 is inserted and removed.

  As shown in FIGS. 8A and 8B, the engagement means composed of the engagement hole 24 and the engagement portion 44 is disengaged, and is urged in the separating direction by the urging means composed of the elastic body 31. Therefore, the filter support 20 pops up, and the insertion port 30 of the filter 5 is separated from the grill 10. Thereby, the filter 5 can be slid and removed from the filter support 20.

  Further, since the grill 10 and the insertion port 30 are separated from each other, the contact between the filter 5 and the grill 10 can be prevented. Therefore, it is possible to prevent falling of dust or the like that is captured by the filter 5 and attached to the surface thereof.

  In a state where the filter support 20 is popped up, the back side surface in the vicinity of the edge of the engagement hole 24 of the filter support rail 26 abuts on the front side surface of the stopper claw portion 41 of the engagement member 40. That is, the engagement hole 24 and the stopper claw portion 41 have a function as stopper means.

  The stopper means including the stopper claw portion 41 and the engagement hole 24 prevents the grill 10 and the filter support 20 from being excessively separated or separated, and the opening of the filter support 20 and the grill 10 is necessary for filter replacement. It can be suppressed within a suitable range. Thereby, the filter support 20 can be easily accommodated in the grill 10.

  Further, the filter support 20 has a rear surface near the edge of the engagement hole 24 in contact with the front surface of the stopper claw 41 and is urged in the rear direction by the elastic body 31. It is held in a state separated from 10. Therefore, since the pop-up state can be maintained without supporting the filter support 20, the filter 5 can be easily removed and attached.

  In addition, you may employ | adopt the stopper means of a shape different from said engagement hole 24 and the stopper nail | claw part 41. FIG. For example, a claw portion or the like that functions as stopper means may be formed on the edge portion 15 of the grill 10 by contacting the filter support 20.

  As described above, the engagement member 40 functions as a support unit, an engagement unit, and a stopper unit. Thus, by forming the supporting means, the engaging means and the stopper means by one member, the number of parts of the grill assembly 4 can be reduced, and the productivity of the grill assembly 4 can be increased.

  Next, a method of fixing the filter support 20 to the grill 10 and putting it into use will be described with reference to FIGS. The filter support 20 is fixed to the grill 10 by a procedure reverse to the above-described pop-up method.

  Specifically, the filter support 20 is slidable by pushing the filter support 20 in the popped-up state, that is, the state shown in FIGS. 8A and 8B toward the grill 10. That is, the state shown in FIGS. 7A and 7B is obtained.

  Next, by sliding the slidable filter support 20 in the direction opposite to the filter removal direction, the grill assembly 4 is in a use state, that is, as shown in FIGS. 6 (A) and 6 (B). The engaging hole 24 that is the engaging means engages with the engaging portion 44. Thereby, the filter support 20 and the filter 5 inserted therein can be fixed to the grill 10. Thus, the filter 5 can be easily attached.

  FIG. 9A is a detailed view of a portion B of the grill assembly 4 shown in FIG. 2 and shows a state in which the filter 5 is set at the use position. FIG. 9B is a cross-sectional view of the grill assembly 4 taken along the line GG shown in FIG. That is, FIGS. 9A and 9B show the vicinity of the portion B of the grill assembly 4 in the same state as FIGS. 6A and 6B.

Note that, for example, a stopper or the like for preventing the passage of the filter 5 may be provided in the vicinity of one insertion port 130, and the filter 5 may be inserted and removed from one side.

  Support holes 125 (support means) are formed in the vicinity of both ends of the filter support rail 126, respectively. A support pin 135 (support means) described later provided in the grill 110 is inserted into the support hole 125.

  A latch 137 is provided at approximately the center of each of the pair of filter support rails 126 as detachable engaging means for fixing the grill 110 and the filter support 120 so that the filter 5 is in a predetermined use position. In addition, an engagement receiving portion 138 that engages with the latch 137 is attached to the grill 110 corresponding to the position of the latch 137. For each of the filter support rails 126, by providing the engaging means at one substantially central position, the number of parts can be reduced and the engagement / disengagement operation can be easily performed.

  At the approximate center of each of the pair of filter support rails 126, there is an elastic force that biases the filter support 120 in the separation direction between the filter support rail 126 and the grill 110, corresponding to the position of the latch 137 that is the engaging means. A body 131 (biasing means) is provided. By providing the urging means corresponding to the position of the engaging means, it is possible to suppress the deflection of the filter support rail 126 in a state where the filter support 120 is set at the use position.

  A rail fixing member 122 that connects the filter support rails 126 is provided at substantially the center of the pair of filter support rails 126. Thereby, the rail fixing member 122 fixes the pair of filter support rails 126 substantially in parallel.

  12A and 12B are cross-sectional views taken along the line II of the grill assembly 104 in the vicinity of the portion H shown in FIG. 11, and FIG. 12A is a state in which the filter support 120 is set at the use position. FIG. 12B shows a state where the filter support 120 is popped up.

  As shown in FIG. 12A, a mounting portion 134 that protrudes from the rear side is formed inside the grill 110. A support pin 135 formed by inserting a screw or the like through a substantially cylindrical sleeve or the like is fixed to the end portion of the attachment portion 134, and a stopper portion 132 is provided at the end portion of the support pin 135 opposite to the grill 110. Is formed.

  The support pin 135 is inserted through a support hole 125 formed in the flange portion 123 of the filter support rail 126. Thereby, the filter support 120 can be separated from the grill 110 in a substantially vertical direction.

  A latch 137 is provided on the back side of the rail fixing member 122. The latch 137 includes a claw portion 139 that protrudes from the side surface on the engagement receiving portion 138 side (the right side in FIG. 12A) and a convex portion 155 that protrudes from the back side of the latch 137.

  The claw portion 139 of the latch 137 is urged in the projecting direction (rightward in FIG. 12A) by an elastic body (not shown) provided in the main body of the latch 137. Accordingly, the claw portion 139 protrudes from the main body of the latch 137 in a normal state, and is stored in the main body of the latch 137 when an external force that pushes into the main body of the latch 137 is applied.

  In the state of use, the surface on the back side of the claw portion 139 contacts and engages the surface on the grill 110 side (front side) of the engagement receiving portion 138 provided on the grill 110. Accordingly, the claw portion 139 and the engagement receiving portion 138 function as engagement means, and the filter support 120 can be fixed to the grill 110.

  The convex portion 155 of the latch 137 is interlocked with the claw portion 139. That is, by sliding the convex portion 155, a force in the storing direction or the protruding direction can be applied to the claw portion 139. By sliding the convex portion 155, the claw portion 139 can be accommodated in the main body of the latch 137, whereby the engagement between the claw portion 139 and the engagement receiving portion 138 can be released.

  The filter support 120 is urged by the elastic body 131 in a direction away from the grill 110. That is, the claw portion 139 of the latch 137 is urged toward the engagement receiving portion 138. Thereby, engagement with the nail | claw part 139 and the engagement receiving part 138 can be strengthened, and the shakiness of the filter support tool 120 can be suppressed.

  As shown in FIG. 12B, the claw portion 139 is accommodated in the main body of the latch 137 by sliding the convex portion 155 of the latch 137 toward the opposite side of the claw portion 139. Thereby, the engagement between the claw portion 139 and the engagement receiving portion 138 can be released.

  Further, since the filter support 120 is urged in the separating direction by the elastic body 131, it pops up from the grill 110. Thereby, the filter 5 can be easily inserted and removed.

  The back side surface of the filter support rail 126 near the edge of the support hole 125 abuts on the front side of the stopper part 132 of the support pin 135. Thereby, the separation of the filter support 120 from the grill 110 is limited. That is, the support hole 125 and the stopper portion 132 function as stopper means.

  Further, the inner surface of the engagement receiving portion 138 comes into contact with the rear surface of the filter support 120. Thereby, the filter support 120 is restricted from being separated from the grill 110. That is, the engagement receiving part 138 functions as a stopper means.

  When the filter 5 is mounted and the filter support 120 is set at the use position, the filter support 120 is pushed toward the grill 110. Thereby, the filter support 120 can be easily fixed to the grill 110.

  Specifically, the front side of the claw portion 139 and the back side of the engagement receiving portion 138 are brought into contact with each other by pushing the filter support 120 in the separated state, that is, the state shown in FIG. . Here, since the front side of the claw portion 139 is formed obliquely, a force in the storing direction acts on the claw portion 139, and the claw portion 139 is stored in the main body of the latch 137.

  When the filter support 120 is pushed to a predetermined use position, the claw portion 139 is biased in the protruding direction by an elastic body (not shown) in the latch 137 body, and thus protrudes from the body of the latch 137. Engage with the receiving part 138. That is, the use state shown in FIG. In this way, the filter support 120 can be easily fixed to the grill 110.

  Further, when the filter support 120 is pushed toward the grill 110, the flange portion 123 of the filter support rail 126 comes into contact with the end portion of the attachment portion 134. Thereby, it can prevent that the filter support tool 120 is pushed in excessively.

  In the embodiment described above, the filter supports 20 and 120 are supported by the grilles 10 and 110 by the support means that can be separated, but the filter mounting structure of the present invention is not limited to this.

For example, the filter support 20 or the like may be attached to a support frame or the like that is provided separately, instead of the grill 10 or the like, by support means that can be separated. That is, an assembly of the filter support 20 or the like capable of popping up may be configured by the filter support 20 or the like and a support frame or the like that supports the filter support 20 or the like so as to be separated. Then, a support frame or the like of the assembly having the pop-up function may be attached to the inside of the grill 10 or the like. This also allows the filter support 20 or the like to pop up from the grill 10 or the like.
In addition, various modifications can be made without departing from the scope of the present invention.
