Description

本発明は、天井パネル装置に関する。 The present invention relates to a ceiling panel device.

従来より、天井に設けられる点検口を開閉する点検口パネルが知られている。
例えば、下記特許文献１には、任意の１辺を開閉中心として点検開口部を開閉する蓋体を備えた蓋施錠装置が開示されている。また、この蓋施錠装置は、点検開口部周囲の開閉方向に対して直交する幅方向両側の天井パネル材のそれぞれに、この蓋体の開閉自由端部に設けられた被施錠部を保持する施錠器が設置される構成とされている。 Conventionally, an inspection port panel for opening and closing an inspection port provided on the ceiling has been known.
For example, Patent Document 1 below discloses a lid locking device including a lid that opens and closes an inspection opening with an arbitrary side as a center for opening and closing. Further, this lid locking device holds a locked portion provided at the openable / closable end of the lid on each of the ceiling panel materials on both sides in the width direction orthogonal to the opening / closing direction around the inspection opening. It is configured so that the vessel is installed.

特開２０１８−２０４３６９号公報JP-A-2018-204369

しかしながら、上記特許文献１に記載された蓋施錠装置では、蓋体の開閉自由端部に対向される天井パネル材の幅方向両側が両側の野縁に固定され、また、蓋体の開閉自由端部の被施錠部が幅方向両側の天井パネル材のそれぞれに設けられた施錠器に保持される。そのため、互いに対向する蓋体の開閉自由端部及び天井パネル材の端部の幅方向途中部位において垂れ下がり等が生じ易くなることが考えられ、これら端部同士に段差が生じ易くなることが考えられる。 However, in the lid locking device described in Patent Document 1, both sides of the ceiling panel material facing the open / close free end of the lid are fixed to the field edges on both sides in the width direction, and the open / close free end of the lid is also fixed. The locked portion of the portion is held by a locker provided on each of the ceiling panel materials on both sides in the width direction. Therefore, it is conceivable that the openable and closable ends of the lids facing each other and the end portion of the ceiling panel material are likely to hang down in the middle of the width direction, and it is conceivable that a step is likely to occur between these end portions. ..

本発明は、上記実情に鑑みてなされたものであり、互いに対向される点検口パネル及び天井パネルの端部を安定的に保持し得る天井パネル装置を提供することを目的としている。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ceiling panel device capable of stably holding an inspection port panel facing each other and an end portion of the ceiling panel.

In addition, a crosspiece-shaped member arranged on the first edge side of the four peripheral edges for partitioning the inspection port provided on the ceiling, an inspection port panel for opening and closing the inspection port, and the first end in the first direction are the inspection port. A ceiling panel arranged so as to face the second end portion in the first direction of the panel is provided, and the crosspiece-shaped member is provided with a second direction portion of the second end portion in the first direction of the inspection port panel. It is characterized in that a holding portion for holding the intermediate portion in a detachable manner and a holding portion for holding the intermediate portion in the second direction of the first end portion in the first direction of the ceiling panel are provided.

本発明に係る天井パネル装置は、上述のような構成としたことで、互いに対向される点検口パネル及び天井パネルの端部を安定的に保持することができる。 The ceiling panel device according to the present invention has the above-described configuration, so that the inspection port panels facing each other and the ends of the ceiling panels can be stably held.

If the end face covering piece portion 23 is provided in this way, the strength of the reinforcing portion 20 can be improved. Further, it is possible to prevent the panel body 10 from being damaged by the jig 49 inserted into the gap between the second end portion 4 and the first edge portion 7.
The end face covering piece portion 23 has a plate shape along the thickness direction in the first direction. The end face covering piece portion 23 may be provided over at least a nearby portion including a portion where the locking portion 30 is provided, or may be provided over substantially the entire base plate-shaped portion 21. In the illustrated example, the lower end of the end face covering piece 23 is positioned slightly above the indoor side surface of the panel body 10, but the present invention is not limited to this mode.

取付部２２は、上記同様、ベース板状部２１の第１方向内側端部から第１方向内側に向けて延出するように一連状に設けられ、ベース板状部２１と同厚さの片部状とされている。この取付部２２は、図２（ｂ）及び図７に示すように、上記同様な取付具１９を介して第２端部４に固定されている。このような構成とすれば、上記と概ね同様、補強部２０を第２端部４に言わば機械的に固定することができる。
また、上記同様、取付部２２及び取付具１９を、ベース板状部２１の長手方向に間隔を空けて複数箇所（図例では、３箇所）に設けた例を示している。また、これら複数の取付部２２及び取付具１９のうちの一つを、係止部３０が設けられた略中央部位に設けた構成としている。なお、補強部２０をパネル本体１０に対して固定する態様としては、このような構成に限られず、その他、種々の変形が可能である。また、この補強部２０は、適宜の金属系材料からプレスや折曲加工等によって一連状に形成されたものでもよい。 Similar to the above, the mounting portion 22 is provided in a series so as to extend from the inner end portion in the first direction of the base plate-shaped portion 21 toward the inner side in the first direction, and is a piece having the same thickness as the base plate-shaped portion 21. It is said to be a part. As shown in FIGS. 2B and 7, the mounting portion 22 is fixed to the second end portion 4 via the same mounting tool 19 as described above. With such a configuration, the reinforcing portion 20 can be mechanically fixed to the second end portion 4 in the same manner as described above.
Further, similarly to the above, an example is shown in which the mounting portion 22 and the mounting tool 19 are provided at a plurality of locations (three locations in the figure) at intervals in the longitudinal direction of the base plate-shaped portion 21. Further, one of the plurality of mounting portions 22 and mounting tools 19 is provided at a substantially central portion where the locking portion 30 is provided. The mode of fixing the reinforcing portion 20 to the panel main body 10 is not limited to such a configuration, and various other modifications are possible. Further, the reinforcing portion 20 may be formed in a series from an appropriate metal-based material by pressing, bending or the like.

係止部３０は、図５（ａ）及び図９に示すように、第２端部４に固定されたベース部２５に対して第２方向に沿ってスライド自在に、かつ第１方向に沿う軸（支持軸）２７回りに回転自在に保持されている。この係止部３０は、当該係止部３０の支持軸２７回りの回転を伴い摘み部３６が突出位置とされる構成とされている。ベース部２５は、係止部３０が係止位置と解除手前位置との間を第２方向にスライドされる際には支持軸２７回りの回転を抑止する一方、解除位置とされた係止部３０の支持軸２７回りの回転を許容する構成とされている。このような構成とすれば、係止部３０は、第２端部４に固定されたベース部２５に対して支持軸２７回りの回転を抑止された状態で係止位置と解除手前位置との間を第２方向にスライド自在に保持されることとなる。これにより、係止部３０が係止位置と解除手前位置との間をスライドされる際には、摘み部３６が非突出位置であるので摘み部３６を目立ち難くすることができる。また、係止部３０を解除位置とし、係止部３０を支持軸２７回りに回転させて摘み部３６を突出位置とすれば、この摘み部３６を把持して点検口パネル２を開放させることができる。また、例えば、パネル厚さ方向に押込み操作することで開錠されるものと比べて、操作部３４を操作する治具４９の差込寸法を効果的に小さくすることができ、治具４９の他部材への干渉等を抑制することができる。 As shown in FIGS. 5A and 9, the locking portion 30 is slidable along the second direction with respect to the base portion 25 fixed to the second end portion 4, and is along the first direction. It is rotatably held around a shaft (support shaft) 27. The locking portion 30 is configured such that the knob portion 36 is in a protruding position as the locking portion 30 rotates around the support shaft 27. The base portion 25 suppresses rotation around the support shaft 27 when the locking portion 30 is slid between the locking position and the position before the release in the second direction, while the locking portion is the unlocked position. It is configured to allow rotation of 30 around the support shaft 27. With such a configuration, the locking portion 30 is in a state where the rotation around the support shaft 27 is suppressed with respect to the base portion 25 fixed to the second end portion 4, and the locking portion 30 is in the locking position and the position before the release. The space is slidably held in the second direction. As a result, when the locking portion 30 is slid between the locking position and the position before the release, the grip portion 36 is in the non-protruding position, so that the grip portion 36 can be made inconspicuous. Further, if the locking portion 30 is set to the release position and the locking portion 30 is rotated around the support shaft 27 to set the grip portion 36 to the protruding position, the grip portion 36 is gripped and the inspection port panel 2 is opened. Can be done. Further, for example, the insertion dimension of the jig 49 for operating the operation unit 34 can be effectively reduced as compared with the one that is unlocked by pushing in the panel thickness direction, and the jig 49 can be unlocked. Interference with other members can be suppressed.

ベース部２５は、図５（ａ）及び図７に示すように、第２方向に長尺状とされている。このベース部２５は、補強部２０のベース板状部２１上に載置状態で固定されている（図２（ｂ）及び図９等も参照）。また、このベース部２５の長手方向両端部には、当該ベース部２５を補強部２０に固定する固着具の止着部２６，２６が設けられている。ベース部２５は、これら長手方向両側の止着部２６，２６を含んでパネル厚さ方向に厚さ方向を沿わせた略板状とされている。図例では、これら止着部２６，２６に、固着具の軸部が止着される雌ねじ穴や下穴等の止着穴をパネル厚さ方向に開口させるように設けた例を示している。補強部２０には、これら止着部２６，２６上に重ね合わせられるように配されるベース固定片部２４，２４が設けられている。これらベース固定片部２４，２４は、ベース板状部２１の第１方向内側端部から上方側（天井下地９側）に向けて立ち上がるように設けられた立上片部の上端部から第１方向外側に向けて延出するように設けられている。また、これらベース固定片部２４，２４に、止着部２６，２６の止着穴に応じた位置となるように固着具の軸部が挿通される挿通孔を設けた構成としている。 As shown in FIGS. 5A and 7, the base portion 25 has an elongated shape in the second direction. The base portion 25 is fixed on the base plate-shaped portion 21 of the reinforcing portion 20 in a mounted state (see also FIGS. 2B and 9). Further, at both ends of the base portion 25 in the longitudinal direction, fastening portions 26, 26 of a fixing tool for fixing the base portion 25 to the reinforcing portion 20 are provided. The base portion 25 has a substantially plate shape along the thickness direction in the panel thickness direction, including the fastening portions 26, 26 on both sides in the longitudinal direction. In the illustrated example, examples are shown in which the fastening portions 26, 26 are provided with fastening holes such as female screw holes and pilot holes to which the shaft portion of the fastener is fastened so as to open in the panel thickness direction. .. The reinforcing portion 20 is provided with base fixing piece portions 24, 24 arranged so as to be superposed on the fastening portions 26, 26. These base fixing piece portions 24, 24 are first from the upper end portion of the rising piece portion provided so as to rise from the inner end portion in the first direction of the base plate-shaped portion 21 toward the upper side (ceiling base 9 side). It is provided so as to extend outward in the direction. Further, the base fixing pieces 24, 24 are provided with insertion holes through which the shaft portion of the fastener is inserted so as to be positioned according to the fastening holes of the fastening portions 26, 26.

このベース部２５は、補強部２０のベース板状部２１上に固定された状態で、図２（ｂ）に示すように、第１方向外側面が補強部２０の端面覆い片部２３の表面と略同一平面状となるように設けられている（図１１も参照）。
また、このベース部２５には、図５（ａ）及び図７に示すように、係止部３０を回転自在に保持する支持軸２７が設けられている。この支持軸２７は、ベース部２５の長手方向略中央部に位置し、第１方向外側に向けて突出するように設けられている。また、この支持軸２７は、略板状とされたベース部２５の長手方向略中央部の第１方向内側部位から上方側（天井下地９側）に向けて突出するように設けられた部位に設けられている。 As shown in FIG. 2B, the base portion 25 is fixed on the base plate-shaped portion 21 of the reinforcing portion 20, and the outer surface in the first direction is the surface of the end face covering piece portion 23 of the reinforcing portion 20. (See also FIG. 11).
Further, as shown in FIGS. 5A and 7, the base portion 25 is provided with a support shaft 27 for rotatably holding the locking portion 30. The support shaft 27 is located at a substantially central portion in the longitudinal direction of the base portion 25, and is provided so as to project outward in the first direction. Further, the support shaft 27 is provided at a portion of the base portion 25 having a substantially plate shape so as to project upward from the inner portion in the first direction of the substantially central portion in the longitudinal direction toward the upper side (ceiling base 9 side). It is provided.

また、このベース部２５には、本実施形態では、図９に示すように、係止部３０が解除手前位置から解除位置にスライドされる際に係止部３０に設けられた被当接部３１ａに当接され、摘み部３６を突出させる側に回転させるガイド部２９が設けられている。このような構成とすれば、係止部３０を解除手前位置から解除位置にスライドさせれば、ベース部２５のガイド部２９のガイド作用によって摘み部３６が突出する側に係止部３０が回転され、摘み部３６の突出位置側への回転操作性を向上させることができる。本実施形態では、このガイド部２９は、摘み部３６が突出位置から非突出位置に変位する際に、係止部３０に設けられた被当接部３１ａに当接され、非突出位置の手前位置において係止部３０の非突出位置側への回転を制動する制動部としても機能する。このような構成とすれば、非突出位置側に変位される摘み部３６が制動され、この制動に抗して摘み部３６を非突出位置に変位させる必要が生じる。これにより、摘み部３６の非突出位置側への回転が不十分でガイド部２９に制動された位置では摘み部３６が突出することとなる。この結果、作業者に対して摘み部３６が非突出位置となっていないこと、つまり、係止部３０が係止位置となっていないことを認識させることができる。つまりは、作業者に作業未完状態であることを認識させることができ、係止部３０を係止側に操作することを促すことができる。なお、ガイド部２９及び被当接部３１ａの具体的構成については、後述する。 Further, in the present embodiment, the base portion 25 is provided with a contacted portion provided on the locking portion 30 when the locking portion 30 is slid from the position before the release to the release position, as shown in FIG. A guide portion 29 is provided which is brought into contact with the 31a and is rotated to the side where the knob portion 36 is projected. With such a configuration, if the locking portion 30 is slid from the release front position to the release position, the locking portion 30 rotates to the side where the grip portion 36 protrudes due to the guide action of the guide portion 29 of the base portion 25. Therefore, the rotational operability of the grip portion 36 toward the protruding position side can be improved. In the present embodiment, when the grip portion 36 is displaced from the protruding position to the non-protruding position, the guide portion 29 is brought into contact with the contacted portion 31a provided in the locking portion 30 and is in front of the non-protruding position. It also functions as a braking portion that brakes the rotation of the locking portion 30 toward the non-protruding position side at the position. With such a configuration, the grip portion 36 displaced to the non-protruding position side is braked, and it becomes necessary to displace the grip portion 36 to the non-protruding position against this braking. As a result, the grip portion 36 protrudes at the position where the rotation of the grip portion 36 toward the non-protruding position side is insufficient and the brake portion 29 is braked. As a result, it is possible to make the operator recognize that the grip portion 36 is not in the non-protruding position, that is, the locking portion 30 is not in the locking position. That is, it is possible to make the operator recognize that the work is incomplete, and to urge the locking portion 30 to be operated on the locking side. The specific configuration of the guide portion 29 and the contacted portion 31a will be described later.

係止部３０は、図８（ａ）及び図９（ａ）に示すように、係止状態で第２方向に長尺状とされ、図８（ｃ）、図９（ｃ）及び図１０に示すように、解除状態でパネル厚さ方向に長尺状とされている。この係止部３０は、第１方向に厚さ方向を沿わせた概ね板状とされている。本実施形態では、この係止部３０に、ベース部２５に設けられた支持軸２７が挿通される軸挿通孔３２を第１方向に貫通させて設けた構成としている。また、この軸挿通孔３２を、係止部３０が係止状態で第２方向に長尺な長孔状としている。つまり、係止部３０は、ベース部２５の支持軸２７が挿通された軸挿通孔３２の長径方向に沿って、ベース部２５に対して係止位置と解除手前位置との間を第２方向にスライド自在とされている。この係止部３０の軸挿通孔３２の長径方向一方側端部に支持軸２７が位置した状態が係止部３０の係止位置（摘み部３６の非突出位置）とされる。一方、この係止部３０の軸挿通孔３２の長径方向他方側端部に支持軸２７が位置した状態が係止部３０の解除位置（摘み部３６の突出位置）とされる。なお、このような態様に代えて、係止部３０側に軸を設け、ベース部２５側に軸挿通孔を設けた構成等としてもよい。 As shown in FIGS. 8 (a) and 9 (a), the locking portion 30 has an elongated shape in the second direction in the locked state, and the locking portion 30 has an elongated shape in the second direction, and is shown in FIGS. 8 (c), 9 (c) and 10 (c). As shown in, it is elongated in the panel thickness direction in the released state. The locking portion 30 has a substantially plate shape along the thickness direction in the first direction. In the present embodiment, the locking portion 30 is provided with a shaft insertion hole 32 through which the support shaft 27 provided in the base portion 25 is inserted so as to penetrate in the first direction. Further, the shaft insertion hole 32 has a long hole shape that is long in the second direction with the locking portion 30 locked. That is, the locking portion 30 has a second direction between the locking position and the position before the release with respect to the base portion 25 along the major axis direction of the shaft insertion hole 32 into which the support shaft 27 of the base portion 25 has been inserted. It is said to be slidable. The state in which the support shaft 27 is located at one end of the shaft insertion hole 32 in the major axis direction of the locking portion 30 is defined as the locking position of the locking portion 30 (non-protruding position of the knob portion 36). On the other hand, the state in which the support shaft 27 is located at the other end of the shaft insertion hole 32 of the locking portion 30 in the major axis direction is defined as the unlocking position of the locking portion 30 (protruding position of the knob portion 36). Instead of such an embodiment, a shaft may be provided on the locking portion 30 side and a shaft insertion hole may be provided on the base portion 25 side.

この係止部３０の軸挿通孔３２は、係止状態で第２方向に長尺状とされた係止部３０の長手方向略中央部に設けられている。この係止部３０とベース部２５とは、軸挿通孔３２を介して支持軸２７に止着されたねじ等の固着具３９によって互いの第１方向への移動が規制された状態で連結されている。図例では、軸挿通孔３２の第１方向内側を第１方向外側よりも小径状として軸挿通孔３２の軸方向途中部位に第１方向外側に向く段底部を設け、この段底部を、固着具３９の頭部の鍔状部と支持軸２７の基端部とによって挟み込んだような構成とした例を示している。なお、係止部３０とベース部２５とを第１方向に移動不能に連結する態様としては、このような態様に限られず、その他、種々の変形が可能である。 The shaft insertion hole 32 of the locking portion 30 is provided at a substantially central portion in the longitudinal direction of the locking portion 30 which is elongated in the second direction in the locked state. The locking portion 30 and the base portion 25 are connected to each other in a state in which movement in the first direction is restricted by a fixing tool 39 such as a screw fastened to the support shaft 27 via a shaft insertion hole 32. ing. In the illustrated example, the inside of the shaft insertion hole 32 in the first direction has a smaller diameter than the outside of the first direction, and a step bottom portion facing the outside in the first direction is provided in the middle portion of the shaft insertion hole 32 in the axial direction, and the step bottom is fixed. An example is shown in which the tool 39 is sandwiched between the collar-shaped portion of the head and the base end portion of the support shaft 27. The mode in which the locking portion 30 and the base portion 25 are immovably connected in the first direction is not limited to such a mode, and various other modifications are possible.

また、この係止部３０には、図５及び図９に示すように、係止位置と解除手前位置との間をスライドする際に、ベース部２５に設けられた支持面部２８に当接されて回転が規制される被支持面部３１が設けられている。ベース部２５の支持面部２８は、上方側（天井下地９側）に向くように、かつ支持軸２７の下方側（室内側）において第２方向に延びるように設けられている。図例では、この支持面部２８を、上記のように略板状とされたベース部２５の第１方向外側部位に上方側及び第１方向外側に向けて開口するように設けられた凹所の底面とした例を示している。換言すれば、ベース部２５に、係止部３０の被支持面部３１が設けられた部位を受け入れる凹所を形成するように、ベース部２５の第１方向外側部位を他の部位よりも薄くした構成としている。 Further, as shown in FIGS. 5 and 9, the locking portion 30 is brought into contact with the support surface portion 28 provided on the base portion 25 when sliding between the locking position and the position before the release. A supported surface portion 31 whose rotation is restricted is provided. The support surface portion 28 of the base portion 25 is provided so as to face the upper side (ceiling base 9 side) and extend in the second direction on the lower side (indoor side) of the support shaft 27. In the illustrated example, the support surface portion 28 is a recess provided so as to open upward and outward in the first direction at the outer portion in the first direction of the base portion 25 which is formed into a substantially plate shape as described above. An example with the bottom surface is shown. In other words, the first-direction outer portion of the base portion 25 is made thinner than the other portions so as to form a recess in the base portion 25 for receiving the portion provided with the supported surface portion 31 of the locking portion 30. It has a structure.

係止部３０の被支持面部３１は、係止状態で下方側（室内側）に向くように、かつ軸挿通孔３２の下方側において第２方向に延びるように設けられている。また、この被支持面部３１は、係止部３０の第１方向内側に向く面から第１方向内側に向けて突出するように、かつ軸挿通孔３２を囲むように設けられた突部の外周面によって構成されている。この被支持面部３１と支持面部２８とが対面されて互いに略平行状に配された状態では、ベース部２５に対する係止部３０の支持軸２７回りの回転が抑止される。また、係止部３０には、図９（ｃ）及び図１０に示すように、摘み部３６が突出位置とされた状態で、ベース部２５の支持面部２８に対面されて支持軸２７に対する係止部３０の下方側への移動を抑止するストッパー面３１ｂが設けられている。このストッパー面３１ｂは、被支持面部３１の第２方向他方側（軸挿通孔３２の長径方向他方側）に連なるように設けられ、摘み部３６が非突出位置で第２方向他方側を向き、かつ摘み部３６が突出位置で下方側を向くように設けられている。被支持面部３１とストッパー面３１ｂとの境界部は、係止部３０が解除状態において摘み部３６が非突出位置と突出位置との間を変位（回転）可能なように突湾曲面状とされている。このストッパー面３１ｂは、突出位置とされた摘み部３６の非突出側とは異なる側への変位を抑止する構成とされている。 The supported surface portion 31 of the locking portion 30 is provided so as to face downward (indoor side) in the locked state and to extend in the second direction on the lower side of the shaft insertion hole 32. Further, the supported surface portion 31 is provided so as to project inward in the first direction from the surface of the locking portion 30 facing inward in the first direction and to surround the shaft insertion hole 32. It is composed of faces. In a state where the supported surface portion 31 and the supporting surface portion 28 are faced to each other and arranged substantially parallel to each other, the rotation of the locking portion 30 with respect to the base portion 25 around the support shaft 27 is suppressed. Further, as shown in FIGS. 9C and 10, the locking portion 30 faces the support surface portion 28 of the base portion 25 and engages with the support shaft 27 in a state where the knob portion 36 is in the protruding position. A stopper surface 31b for suppressing the downward movement of the stop portion 30 is provided. The stopper surface 31b is provided so as to be connected to the other side of the supported surface portion 31 in the second direction (the other side in the major axis direction of the shaft insertion hole 32), and the knob portion 36 faces the other side in the second direction at a non-protruding position. Moreover, the knob portion 36 is provided so as to face downward at the protruding position. The boundary between the supported surface portion 31 and the stopper surface 31b has a curved surface shape so that the knob portion 36 can be displaced (rotated) between the non-protruding position and the protruding position when the locking portion 30 is released. ing. The stopper surface 31b is configured to suppress displacement of the knob portion 36, which is set to the protruding position, to a side different from the non-protruding side.

また、本実施形態では、被支持面部３１に連なるように被当接部３１ａを設けた構成としている。被当接部３１ａは、被支持面部３１の第２方向一方側（軸挿通孔３２の長径方向一方側）に連なるように設けられ、突湾曲面状とされている。
ベース部２５のガイド部２９は、図９（ｂ）の二点鎖線にて示すように、解除手前位置の係止部３０の被当接部３１ａに当接するように設けられている。このガイド部２９は、支持面部２８の第２方向一方側（軸挿通孔３２の長径方向一方側）に位置するように設けられている（図５（ａ）及び図７等も参照）。また、このガイド部２９の上面は、解除手前位置から解除側に係止部３０が移動する際に、被当接部３１ａを上昇させるように支持面部２８よりも上方側に位置し、かつ支持面部２８から離れるに従い上るように傾斜する傾斜面状とされている。
また、このガイド部２９は、支持面部２８との間に隙間を隔てて設けられ、上記したベース部２５の凹所の第２方向一方側を区画する内側壁から第２方向他方側に向けて突出するように片持ち片部状に設けられている。このガイド部２９は、被当接部３１ａの当接によって僅かに弾性変形される構成とされている。 Further, in the present embodiment, the contacted portion 31a is provided so as to be connected to the supported surface portion 31. The contacted portion 31a is provided so as to be connected to one side of the supported surface portion 31 in the second direction (one side in the major axis direction of the shaft insertion hole 32), and has a curved surface shape.
As shown by the alternate long and short dash line in FIG. 9B, the guide portion 29 of the base portion 25 is provided so as to abut the contacted portion 31a of the locking portion 30 at the position before the release. The guide portion 29 is provided so as to be located on one side of the support surface portion 28 in the second direction (one side in the major axis direction of the shaft insertion hole 32) (see also FIGS. 5A and 7). Further, the upper surface of the guide portion 29 is located above the support surface portion 28 so as to raise the contacted portion 31a when the locking portion 30 moves from the position in front of the release to the release side, and supports the guide portion 29. It has an inclined surface shape that inclines so as to rise as the distance from the surface portion 28 increases.
Further, the guide portion 29 is provided with a gap between the guide portion 29 and the support surface portion 28, and is directed from the inner side wall that partitions one side of the recess of the base portion 25 in the second direction toward the other side in the second direction. It is provided in a cantilever shape so as to protrude. The guide portion 29 is configured to be slightly elastically deformed by the contact of the contacted portion 31a.

上記のような構成により、係止部３０を解除手前位置から解除側に移動させれば、図９（ｂ）の実線にて示すように、係止部３０の被当接部３１ａがガイド部２９に乗り上げるようにして上方側に変位する。また、この被当接部３１ａの上方側への変位を伴って摘み部３６が非突出位置から突出側となる下方側に変位する（図８（ａ）、（ｂ）も参照）。これにより、後記する摘み部３６がパネル本体１０の室内側に向く表面よりも室内側に突出し、摘み部３６を手指等で引出可能となる。
一方、摘み部３６を突出側から非突出側へ変位させる際には、図９（ｂ）の実線にて示すように、非突出位置の手前位置において係止部３０の被当接部３１ａがガイド部２９に当接し、非突出側への変位が制動される。この状態では、上記同様、摘み部３６がパネル本体１０の室内側に向く表面よりも室内側に突出した状態とされる。この状態から摘み部３６を押し込むようにして上方側に変位させれば、被当接部３１ａが当接されたガイド部２９の弾性変形及びガイド作用を伴って係止部３０が解除位置から解除手前位置に変位し、摘み部３６が非突出位置とされる。 When the locking portion 30 is moved from the front position to the unlocking side by the above configuration, the contacted portion 31a of the locking portion 30 becomes the guide portion as shown by the solid line in FIG. 9B. It is displaced upward so as to ride on 29. Further, the grip portion 36 is displaced from the non-protruding position to the downward side which is the protruding side with the displacement of the contacted portion 31a upward (see also FIGS. 8A and 8B). As a result, the knob portion 36, which will be described later, protrudes toward the room side from the surface of the panel body 10 facing the room side, and the knob portion 36 can be pulled out by a finger or the like.
On the other hand, when the knob portion 36 is displaced from the protruding side to the non-protruding side, as shown by the solid line in FIG. 9B, the contacted portion 31a of the locking portion 30 is placed in front of the non-protruding position. It comes into contact with the guide portion 29, and the displacement to the non-protruding side is braked. In this state, similarly to the above, the knob portion 36 is in a state of protruding toward the room side from the surface of the panel body 10 facing the room side. If the knob portion 36 is pushed in from this state and displaced upward, the locking portion 30 is released from the released position with elastic deformation and a guide action of the guide portion 29 with which the contacted portion 31a is in contact. It is displaced to the front position, and the knob portion 36 is set to the non-protruding position.
