Description

  The present invention relates to an inspection port device.

  Conventionally, an inspection port provided for inspecting the inside of a wall surface of a building is blocked by an inspection port lid. The inspection palate is opened when the inside of the wall surface is inspected, and is closed after the inspection is completed.

  Patent Document 1 discloses an example of such an inspection opening / closing structure.

  The opening / closing structure of the inspection port described in Patent Document 1 includes an elastic member, a hook portion, and a hook portion on the inner peripheral portion of the inspection port frame. In this open / close structure, the inspection port lid is fixed to the inspection port frame without rattling by engaging the hook portion with the hook portion while pressing the inspection port lid against the elastic member (shrinking the elastic member). The inspection palate can be closed. In addition, the inspection port lid can be opened by releasing the state in which the hook portion is engaged with the hook portion.

JP 2011-144610 A

  However, in the open / close structure described in Patent Document 1, when the engagement state between the hook part and the hook part is released when the inspection opening is opened, the compression force applied to the elastic member is released and the elastic member suddenly moves. There is a risk that the inspection opening lid may jump out of the inspection opening frame to the room side, causing a safety problem. In addition, in the state where the inspection cover is closed, the inspection cover is always receiving the elastic force from the elastic member toward the room, so when the hook part is not properly engaged with the hook part, There is a possibility that the hook part may come off from the hook part and the inspection lid may jump out to the indoor side.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an inspection port device capable of safely opening and closing a lid member.

  In order to solve the above-described problems, the present invention provides a frame member provided along an edge of an inspection port formed in a wall that partitions an indoor space and a wall space, and an opening of the frame member. A plate-like lid member to be attached, wherein the frame member has a wall surface surrounding an outer peripheral surface of the lid member, holds the lid member via an elastic member protruding from the wall surface, and the lid In a state where the member is attached to the frame member, the elastic member protrudes inward from a position facing the outer peripheral surface of the lid member on the wall surface or a position corresponding to the surface of the lid member on the indoor space side. And the natural length of the protrusion direction of the said elastic member is larger than the distance of the outer peripheral surface of the said cover member of the state attached to the said frame member, and the said wall surface, The inspection port apparatus provided is provided.

  According to the present invention, the frame member can stably hold the lid member via the elastic member. That is, when the elastic member protrudes from the position facing the outer peripheral surface of the lid member on the wall surface, the elastic member presses the outer peripheral surface of the lid member, and a frictional force is generated between the elastic member and the lid member. Therefore, the lid member cannot be detached from the frame member unless the user pulls the lid member toward the indoor space with a force larger than the frictional force. On the other hand, when the elastic member protrudes from the position corresponding to the indoor space side surface of the lid member on the wall surface, since the elastic member covers the indoor space side surface of the lid member, the peripheral portion of the lid member is elastic. The lid member cannot be removed from the frame member unless the user pulls the lid member toward the indoor space until the member is moved over.

  In any case, unlike the above-described conventional technology, when removing the lid member from the frame member, the lid member does not jump out into the indoor space. Therefore, according to this invention, the inspection port apparatus which can open and close a cover member safely can be provided.

  In this invention, it is preferable that the said elastic member is arrange | positioned so that it may be pinched | interposed between the outer peripheral surface of the said cover member, and the said wall surface.

  According to this configuration, the elastic force (elastic restoring force) of the elastic member that is elastically deformed acts on the outer peripheral surface of the lid member in a direction perpendicular to the outer peripheral surface. When a force for pulling the lid member toward the indoor space is applied, the lid member receives a frictional force having a magnitude proportional to the elastic force from the elastic member. Therefore, the lid member is firmly held by the frame member by this elastic force and frictional force, and is prevented from falling off from the frame member.

  In this invention, it is preferable that the said frame member hold | maintains the said cover member via the said elastic member elastically deformed so that it may be pinched | interposed between the outer peripheral surface of the said cover member, and the said wall surface.

  According to this configuration, the outer peripheral surface of the lid member is provided with an elastic force perpendicular to the outer peripheral surface, and a frictional force having a magnitude proportional to the elastic force from the elastic member that is elastically deformed so as to collapse. Therefore, the lid member is securely held by the frame member.

  In this invention, it further has a cover member which covers the peripheral part of the said cover member hold | maintained at the said frame member from the indoor side, The said cover member is detachable with respect to the to-be-engaged part formed in the said frame member And a pressing piece for pressing the surface on the indoor space side of the lid member in a state where the lid member is held on the wall surface and the engagement portion is engaged with the engaged portion. It is preferable to comprise.

  According to this configuration, the pressing piece of the cover member presses the lid member in a state where the lid member is held on the wall surface of the frame member and the engaging portion of the cover member is engaged with the engaged portion of the frame member. . That is, when the engaging part of the cover member is engaged with the engaging part of the frame member, the pressing piece of the cover member presses the lid member. Therefore, the lid member can be locked with respect to the frame member by the cover member, and the lid member can be prevented from being detached from the frame member.

  In the present invention, it is preferable that the pressing piece has flexibility.

  According to this configuration, with respect to the lid member having a small thickness, the pressing piece can be elastically deformed to a small extent, the pressing piece can be pressed against the lid member, and the engaging portion can be engaged with the engaged portion. Further, for a cover member having a large thickness, a large amount of pressing pieces can be elastically deformed, the pressing pieces can be pressed against the cover member, and the engaging portion can be engaged with the engaged portion. That is, according to this structure, when a flexible pressing piece has flexibility, when using the cover member from which thickness differs, the difference in the thickness can be absorbed.

  In this invention, it is preferable that the said cover member is integrated with the said frame member via the flexible connection part.

  According to this configuration, the cover member can be moved relative to the frame member while the cover member is connected to the frame member by bending and extending the connecting portion. That is, since the cover member is not completely separated from the frame member, it is possible to prevent the cover member from being lost when the lock is released.

  In this invention, it is preferable that the said tongue piece of a natural state protrudes from the said wall surface in the state inclined to the wall back space side.

  According to this configuration, the lid member can be easily moved along the wall surface from the indoor space side to the wall space side. Further, when the lid member moves to the holding position, the tongue piece reliably falls to the wall space side. Even if the lid member is moved to the indoor side in this state, since the elastic force and the frictional force act on the lid member from the fallen tongue piece, the lid member can be prevented from falling off the frame member.

  In the present invention, one of the engaged portion and the engaging portion is a recess in which a protruding piece is formed on an inner wall surface, and the other of the engaged portion and the engaging portion is increased in thickness. The thick part is a convex part formed at the tip, and when the convex part is inserted into the concave part and the thickened part gets over the protruding piece, the engaging part engages with the engaged part. It is preferable.

  According to this configuration, by thickly pushing the convex portion into the concave portion, the thickened portion can get over the protruding piece, and the convex portion can be easily fitted into the concave portion. In addition, by lightly pulling the convex portion with the convex portion fitted into the concave portion, the thickened portion can get over the protruding piece in the opposite direction to pushing the convex portion, and the convex portion can be easily removed from the concave portion. . Therefore, the engagement portion and the engaged portion can be easily engaged and disengaged, whereby the cover member can be easily locked and unlocked by the cover member.

  In this invention, the said frame member has a support part which supports the surface by the side of the wall space of the said cover member, and the said elastic member supports the surface by the side of the wall space of the said cover member on the said support part. It is preferable that the cover member is disposed so as to cover the surface on the indoor space side of the peripheral edge of the lid member.

  According to this configuration, the lid member is sandwiched between the support member of the frame member and the elastic member, so that the lid member is securely held by the frame member.

  As described above, according to the present invention, it is possible to provide an inspection port device that can safely open and close the lid member.

  That is, as shown in FIG. 11, since the pressing piece 82 is made of a flexible material, the pressing piece 82 is elastically deformed according to the thickness of the decorative sheet 12 to absorb the thickness of the decorative sheet 12. Can do. That is, when the thickness of the decorative sheet 12 is small, the pressing piece 82 is elastically deformed so that the inclination angle is larger than the natural state. When the thickness of the decorative sheet 12 is large, the pressing piece 82 is when the thickness of the decorative sheet 12 is small. It is elastically deformed so that the inclination angle is greatly increased. Thereby, even if the thickness of the decorative sheet 12 is different, the pressing piece 82 can firmly press the surface of the decorative sheet 12 while absorbing the difference in the thickness of the decorative sheet 12.

  When removing the lid member 9 from the frame member 1 in order to check the interior of the wall space S2, the work may be performed in the reverse order of the order in which the lid member 9 is attached to the frame member 1. Specifically, first, the cover member 8 is opened (see FIGS. 7 and 8). Next, the lid member 9 is removed from the frame member 1 by holding the handle (not shown) provided on the surface of the lid member 9 on the indoor space S1 side and pulling the lid member 9 toward the indoor space S1 (see FIG. 6). ). By pulling the lid member 9 toward the indoor space S <b> 1, a frictional force that resists the pulling force acts between the outer peripheral surface 90 of the lid member 9 and the tongue piece 7. However, the lid member 9 can be detached from the frame member 1 by pulling with a force larger than the frictional force.

  As described above, according to the inspection port device 100 according to the present embodiment, the frame member 1 is elastically deformed so as to fall between the outer peripheral surface 90 of the lid member 9 and the holding wall surface 602 of the frame body 2. The lid member 9 is held through the tongue piece 7. That is, the elastic force (elastic restoring force) of the elastically deformed tongue piece 7 acts on the outer peripheral surface 90 of the lid member 9 in a direction perpendicular to the outer peripheral surface 90. When a force for pulling the lid member 9 toward the indoor space S <b> 1 is applied, the lid member 9 receives a frictional force having a magnitude proportional to the elastic force from the tongue piece 7. Therefore, the lid member 9 is firmly held by the frame member 1 by this elastic force and frictional force, and is prevented from falling off from the frame member 1.

  When removing the lid member 9 from the frame body 2, the lid member 9 may be pulled toward the indoor space S1 with a force larger than the frictional force. That is, the lid member 9 cannot be detached from the frame body 2 unless the lid member 9 is pulled toward the indoor space S1 against the frictional force. For this reason, when removing the cover member 9 from the frame main body 2, the cover member 9 does not jump out to the indoor space S1 side vigorously.

  Thus, according to this embodiment, the inspection port apparatus 1 which can open and close the cover member 9 safely can be provided.

  Further, when the convex portion 80 of the cover member 8 is engaged with the concave portion 610 of the frame body 2, the pressing piece 82 of the cover member 8 presses the lid member 9. Therefore, the lid member 9 can be locked with respect to the frame body 2 by the cover member 8 to prevent the lid member 9 from being detached from the frame body 2.

  Further, since the pressing piece 82 is flexible, the pressing piece 82 is elastically deformed to a small extent to press the pressing piece 82 against the lid member 9 with respect to the lid member 9 having a small thickness, and the convex portion 80 is formed into the concave portion 610. Can be engaged. In addition, for the cover member 9 having a large thickness, the pressing piece 82 can be elastically deformed so that the pressing piece 82 is pressed against the lid member 9, and the convex portion 80 can be engaged with the concave portion 610. Accordingly, the pressing piece 82 can absorb the difference in thickness when the lid member 9 having a different thickness is used.

  Further, the cover member 8 is integrated with the side members 2 a to 2 d through a flexible connecting portion 83. Therefore, by bending and extending the connecting portion 83, the cover member 8 can be moved relative to the side members 2a to 2d while the cover member 8 is connected to the side members 2a to 2d. That is, since the cover member 8 is not completely separated from the side members 2a to 2d, it is possible to prevent the cover member 8 from being lost when the lock is released.

  Further, the tongue piece 7 in the natural state protrudes from the holding wall surface 602 while being inclined toward the wall space S2 side. Accordingly, the lid member 9 can be easily moved along the holding wall surface 602 from the indoor space S1 side to the wall space S2 side. Further, when the lid member 9 is inserted into the opening 10 of the frame member 1, the tongue piece 7 reliably falls to the wall space S <b> 2 side. Even if it is attempted to move the lid member 9 to the indoor space S1 in this state, the lid member 9 falls off the frame member 1 because a resilient force and a frictional force act on the lid member 9 from the fallen tongue piece 7. Can be prevented.

  Further, by lightly pushing the convex portion 80 into the concave portion 610, the enlarged diameter portion 801 can get over the flange portion 613, and the convex portion 80 can be easily fitted into the concave portion 610. Further, by gently pulling the convex portion 80 in a state where the convex portion 80 is fitted in the concave portion 610, the diameter-expanded portion 801 gets over the flange-shaped portion 613 in the opposite direction to when the convex portion 80 is pushed. It can be easily removed from the recess 610. Therefore, the convex portion 80 and the concave portion 610 can be easily engaged and disengaged, whereby the cover member 9 can be easily locked and unlocked by the cover member 8.

  In addition, in the said embodiment, although the tongue piece 7 which consists of a soft vinyl chloride resin is provided in the holding wall surface 602 of side member 2a-2d, it is not restricted to this. For example, various elastic bodies may be provided on the holding wall surface 602. For example, rubber, a resin foam, or a leaf spring may be attached to the holding wall surface 602.
