Description
本発明は、天井等に取り付ける化粧パネル取付構造に関するものである。
The present invention relates to a decorative panel mounting structure for mounting on a ceiling or the like.
従来、化粧パネルは、例えば天井に固定される給気グリルの室内側開口を覆って着脱自在に取り付けられる。つまり化粧パネル取付構造は、一般的に、化粧パネルに形成された樹脂材からなる嵌合部が給気グリル本体の室内側に嵌合するものであった。
Conventionally, the decorative panel is detachably attached, for example, covering the indoor opening of the air supply grill fixed to the ceiling. That is, in the decorative panel mounting structure, generally, a fitting portion made of a resin material formed on the decorative panel is fitted to the indoor side of the air supply grill body.
以下、従来の化粧パネル取付構造について図８を参照しながら説明する。
Hereinafter, a conventional decorative panel mounting structure will be described with reference to FIG.
図８は、従来の化粧パネル取付構造を示す側断面図である。図８に示すように、化粧パネル１０１の取付構造は、ボス部１０３とボス受け部１０５とを備える。ボス部１０３は、化粧パネル１０１の裏面か又はフレーム１０２のいずれかに突起部として備えられる。ボス受け部１０５は、ボス部１０３と嵌合する。またボス受け部１０５は、ボス部１０３に設けられた突起部と係合する係合部１０４を備える。
FIG. 8 is a side sectional view showing a conventional decorative panel mounting structure. As shown in FIG. 8, the attachment structure of the decorative panel 101 includes a boss portion 103 and a boss receiving portion 105. The boss 103 is provided as a protrusion on either the back surface of the decorative panel 101 or the frame 102. The boss receiving portion 105 is fitted with the boss portion 103. The boss receiving portion 105 includes an engaging portion 104 that engages with a protrusion provided on the boss portion 103.
さらに上述の取付構造に加えて、１組のボス部１０３とボス受け部１０５のみが、化粧パネル１０１の落下を防止する構造を備えている。これにより、ボス部１０３とボス受け部１０５の係合部１０４の破損が進んだ場合でも、落下防止構造を備えるボス部１０３とボス受け部１０５の嵌合状態に変化は生じない。しかし、落下防止機構を備えないボス部１０３とボス受け部１０５の嵌合状態には変化が生じる。その結果、化粧パネル１０１の保持姿勢に異常が表れ、不具合を目視で気づきやすくするものであった（例えば、特許文献１参照）。
Furthermore, in addition to the mounting structure described above, only one set of the boss portion 103 and the boss receiving portion 105 has a structure that prevents the decorative panel 101 from falling. Thereby, even if the breakage of the engaging portion 104 between the boss portion 103 and the boss receiving portion 105 progresses, the fitting state between the boss portion 103 and the boss receiving portion 105 having the fall prevention structure does not change. However, a change occurs in the fitting state of the boss portion 103 and the boss receiving portion 105 that are not provided with the fall prevention mechanism. As a result, an abnormality appears in the holding posture of the decorative panel 101, and the defect is easily noticed visually (see, for example, Patent Document 1).
このような従来の化粧パネル取付構造の落下を防止する構造においては、１つのボス部に対して化粧パネルの自重が掛かる爪と掛からない爪、すなわち２つの爪を設けることで、爪の劣化に対応するものであった。
In such a structure for preventing the fall of the conventional decorative panel mounting structure, by providing a claw on which the weight of the decorative panel is applied to one boss part and a claw that is not applied, that is, two claws, the deterioration of the nail is caused. It was a corresponding one.
しかしながら、１つのボス部に自重が掛からない爪と自重が掛かる爪とを設けた場合は、自重の掛からない爪について劣化が遅くても、ボス部自体には自重が掛かっている為、ボス部の劣化は進んでいる。そして、化粧パネルの大型化等で化粧パネルが重い場合には、ボス部自体が劣化に耐え切れない可能性があり、爪のみによる対策では不十分であった。
However, when a nail that does not apply its own weight and a nail that applies its own weight are provided on one boss part, the boss part itself is applied with its own weight even if the nail that does not apply its own weight deteriorates slowly. Degradation is progressing. When the decorative panel is heavy due to an increase in the size of the decorative panel or the like, the boss itself may not be able to withstand deterioration, and measures using only the nails are insufficient.
そこで本発明は、上記従来の課題を解決するものであり、化粧パネルを大型化してもボス部の劣化による落下を防止することができる化粧パネル取付構造を提供することを目的とする。
Therefore, the present invention solves the above-described conventional problems, and an object of the present invention is to provide a decorative panel mounting structure that can prevent a drop due to deterioration of a boss portion even if the decorative panel is enlarged.
そして、この目的を達成するために、本発明に係る化粧パネル取付構造は、ボス部とボス部に係合するボス受け部とを係合させて天井埋込形換気扇の本体に化粧パネルを取り付けるための化粧パネル取付構造であって、ボス部及びボス受け部の係合とは独立して係合する、補助ボス部及び補助ボス受け部をさらに備える。ボス部とボス受け部とは、互いに係合する係合構造を備える。また、補助ボス部と補助ボス受け部とは、係合構造による係合が解除された場合にのみ係合する係合補助構造を備える。これにより所期の目的を達成するものである。
And in order to achieve this objective, the decorative panel mounting structure which concerns on this invention engages the boss | hub part and the boss receiving part engaged with a boss | hub part, and attaches a decorative panel to the main body of a ceiling embedded type ventilation fan The structure further includes an auxiliary boss portion and an auxiliary boss receiving portion that are engaged independently of the engagement of the boss portion and the boss receiving portion. The boss part and the boss receiving part have an engaging structure that engages with each other. Further, the auxiliary boss portion and the auxiliary boss receiving portion include an engagement auxiliary structure that engages only when the engagement by the engagement structure is released. This achieves the intended purpose.
本発明によれば、通常時には補助ボス部自体に自重が掛からないため、化粧パネルを大型化してもボス部の劣化による落下を防止するこができる。
According to the present invention, since the weight of the auxiliary boss is not normally applied to the auxiliary boss, the fall of the boss can be prevented even if the decorative panel is enlarged.

続いて、図５、図６を用いて係合構造と補助係合構造との違いについて説明する。
Subsequently, the difference between the engagement structure and the auxiliary engagement structure will be described with reference to FIGS. 5 and 6.
図５は、本発明に係るボス部、ボス受け部、補助ボス部及び補助ボス受け部の関係を示す側面図である。図６は、本発明に係る係合構造と補助係合構造を示す断面図である。図５に示すように、補助ボス受け部２６の端面３９は、ボス受け部２５の端面３８に対して化粧パネル２０側に位置している。これに伴い、補助ボス受け部２６に設けられた副爪受け部４０の端部４６も、ボス受け部２５に設けられた主爪受け部２４の端部４５に対して化粧パネル２０側に位置している。ここで、ボス受け部２５は、複数設けられており、全て略同一形状である。そのため、複数のボス受け部２５の端部４５は、同一平面４７上に位置する。ここで、端部４５は、ボス部２３に設けられた爪２２に当接される面である。つまり、複数のボス受け部２５の、ボス部２３に設けられた爪２２に当接される面が、同一平面４７上に位置する。
FIG. 5 is a side view showing the relationship between the boss portion, the boss receiving portion, the auxiliary boss portion, and the auxiliary boss receiving portion according to the present invention. FIG. 6 is a cross-sectional view showing an engagement structure and an auxiliary engagement structure according to the present invention. As shown in FIG. 5, the end surface 39 of the auxiliary boss receiving portion 26 is positioned on the decorative panel 20 side with respect to the end surface 38 of the boss receiving portion 25. Accordingly, the end portion 46 of the auxiliary claw receiving portion 40 provided in the auxiliary boss receiving portion 26 is also positioned on the decorative panel 20 side with respect to the end portion 45 of the main claw receiving portion 24 provided in the boss receiving portion 25. is doing. Here, a plurality of boss receiving portions 25 are provided, and all have substantially the same shape. Therefore, the end portions 45 of the plurality of boss receiving portions 25 are located on the same plane 47. Here, the end portion 45 is a surface that comes into contact with the claw 22 provided in the boss portion 23. That is, the surfaces of the plurality of boss receiving portions 25 that are in contact with the claws 22 provided on the boss portion 23 are located on the same plane 47.
また、ボス部２３は、複数設けられており、全て略同一形状である。そのため、複数のボス部２３の上端面３５は、同一平面４８上に位置する。また、複数のボス部２３の爪２２における下端面４３も、同一平面４９上に位置している。
Further, a plurality of boss portions 23 are provided, and all have substantially the same shape. Therefore, the upper end surfaces 35 of the plurality of boss portions 23 are located on the same plane 48. Further, the lower end surfaces 43 of the claws 22 of the plurality of boss portions 23 are also located on the same plane 49.
ここで、下端面４３は、ボス受け部２５に設けられた主爪受け部２４に当接される面である。つまり、複数のボス部２３の、ボス受け部２５に設けられた主爪受け部２４に当接される面が、同一平面４９上に位置する。
Here, the lower end surface 43 is a surface that comes into contact with the main claw receiving portion 24 provided in the boss receiving portion 25. That is, the surfaces of the plurality of boss portions 23 that are in contact with the main claw receiving portion 24 provided in the boss receiving portion 25 are located on the same plane 49.
また、本実施の形態では、補助ボス部２７の爪２２における下端面４３も、同一平面４９上位置している。つまり、補助ボス部２７の、補助ボス受け部２６に設けられた副爪受け部４０に当接される面が、同一平面４９上にある。
In the present embodiment, the lower end surface 43 of the claw 22 of the auxiliary boss portion 27 is also located on the same plane 49. That is, the surface of the auxiliary boss portion 27 that is in contact with the auxiliary claw receiving portion 40 provided in the auxiliary boss receiving portion 26 is on the same plane 49.
この構成によれば、図６に示すように、化粧パネル２０がルーバーベース１８に取り付けられた状態において、ボス部２３の爪２２とボス受け部２５の主爪受け部２４とが鉛直方向で係合して固定されるが、補助ボス部２７の爪２２と補助ボス受け部２６の副爪受け部４０とは鉛直方向にて接触しない。
According to this configuration, as shown in FIG. 6, when the decorative panel 20 is attached to the louver base 18, the claw 22 of the boss portion 23 and the main claw receiving portion 24 of the boss receiving portion 25 are engaged in the vertical direction. Although fixed together, the claw 22 of the auxiliary boss portion 27 and the auxiliary claw receiving portion 40 of the auxiliary boss receiving portion 26 do not contact in the vertical direction.
つまり、劣化等により係合構造である爪２２と主爪受け部２４との係合が解除されるまでは、係合補助構造である爪２２と副爪受け部４０とは係合されない。これにより、正常状態では、係合補助構造には化粧パネル２０の自重による負荷が掛からず、自重による劣化は進まない。従って、例えば化粧パネルを大型化しても係合構造に比較して係合補助構造は劣化しないため、係合構造に係る爪２２や主爪受け部２４が破損した場合であっても、係合補助構造が十分な強度で化粧パネルの落下を防止することが可能になる。
That is, until the engagement between the claw 22 that is the engaging structure and the main claw receiving portion 24 is released due to deterioration or the like, the claw 22 that is the engaging auxiliary structure and the sub claw receiving portion 40 are not engaged. Thereby, in the normal state, the load due to the weight of the decorative panel 20 is not applied to the engagement assist structure, and the deterioration due to the weight does not proceed. Therefore, for example, even if the decorative panel is enlarged, the engagement assisting structure does not deteriorate as compared with the engagement structure. Therefore, even when the claw 22 or the main claw receiving portion 24 related to the engagement structure is damaged, the engagement panel is not engaged. The auxiliary structure can prevent the decorative panel from falling with sufficient strength.
本実施の形態では、ボス部２３と補助ボス部２７の形状、大きさを同一とし、ボス受け部２５と補助ボス受け部２６の形状、大きさを変えることで係合構造と、係合補助構造を備える構成とした。ここで、ボス部と補助ボス部の形状、大きさを変え、ボス受け部と補助ボス受け部の形状、大きさを同一とする構成としても、本実施の形態と同様の効果を得ることができる。また、ボス部と、補助ボス部と、ボス受け部と、補助ボス受け部との形状、大きさを変えて、係合構造と、係合補助構造を備える構成としてもよい。
In the present embodiment, the boss portion 23 and the auxiliary boss portion 27 have the same shape and size, and the boss receiving portion 25 and the auxiliary boss receiving portion 26 are changed in shape and size so that the engagement structure and the engagement assist are provided. It was set as the structure provided with a structure. Here, even if the shape and size of the boss portion and the auxiliary boss receiving portion are changed and the shape and size of the boss receiving portion and the auxiliary boss receiving portion are made the same, the same effect as this embodiment can be obtained. it can. Moreover, it is good also as a structure provided with an engagement structure and an engagement auxiliary structure by changing the shape and magnitude | size of a boss | hub part, an auxiliary | assistant boss | hub part, a boss | hub receiving part, and an auxiliary | assistant boss receiving part.
なお、本実施の形態では、ボス部２３とボス受け部２５は４組、補助ボス部２７と補助ボス受け部２６は１組あるとしたが、これに限定されない。例えば、ボス部２３とボス受け部２５は、１組以上あれば化粧パネル２０をルーバーベース１８に取付けることができる。また、補助ボス部２７と補助ボス受け部２６は、２組以上あってもよく、多いほど化粧パネル２０の落下に対する安全性が高くなる。
In the present embodiment, there are four sets of the boss portion 23 and the boss receiving portion 25 and one set of the auxiliary boss portion 27 and the auxiliary boss receiving portion 26. However, the present invention is not limited to this. For example, the decorative panel 20 can be attached to the louver base 18 as long as there is at least one set of the boss portion 23 and the boss receiving portion 25. Further, there may be two or more sets of auxiliary boss portions 27 and auxiliary boss receiving portions 26, and the greater the number, the higher the safety against falling of the decorative panel 20.
また、ボス受け部２５、補助ボス受け部２６共に補強リブ３２を備える。そのため、ボス部２３、補助ボス部２７は、補強リブ３２の曲面３１に接触し沿って、ボス受け部２５、補助ボス受け部２６に挿入される。つまり、ボス部２３、補助ボス部２７をボス受け部２５、補助ボス受け部２６に挿入する際、ボス部２３、補助ボス部２７が直接端面３８、３９に接触しない。これより、ボス受け部２５や補助ボス受け部２６に加わる力が補強リブ３２の全体に分散することになるので、ボス受け部２５の破損に対する耐久性を向上させるとともに、ルーバーベース１８に化粧パネル２０を取り付ける位置決めを容易にすることができる。
Further, both the boss receiving part 25 and the auxiliary boss receiving part 26 are provided with reinforcing ribs 32. Therefore, the boss portion 23 and the auxiliary boss portion 27 are inserted into the boss receiving portion 25 and the auxiliary boss receiving portion 26 along the curved surface 31 of the reinforcing rib 32. That is, when the boss portion 23 and the auxiliary boss portion 27 are inserted into the boss receiving portion 25 and the auxiliary boss receiving portion 26, the boss portion 23 and the auxiliary boss portion 27 do not directly contact the end surfaces 38 and 39. As a result, the force applied to the boss receiving portion 25 and the auxiliary boss receiving portion 26 is dispersed throughout the reinforcing rib 32, so that the durability against damage to the boss receiving portion 25 is improved and the decorative panel is applied to the louver base 18. Positioning for mounting 20 can be facilitated.
また、図７は、本発明に係るボス受け部と補助ボス受け部との位置関係を示す図である。図７に示すように、ボス受け部２５とボス受け部２５に隣接する補助ボス受け部２６との最短距離は、ボス部２３の円筒部４２ａ（図２参照）における円の直径、より詳しくは側壁５０の外面５１の直径よりも短い構成としている。
FIG. 7 is a view showing the positional relationship between the boss receiving portion and the auxiliary boss receiving portion according to the present invention. As shown in FIG. 7, the shortest distance between the boss receiving portion 25 and the auxiliary boss receiving portion 26 adjacent to the boss receiving portion 25 is the diameter of a circle in the cylindrical portion 42a (see FIG. 2) of the boss portion 23, more specifically. The diameter is shorter than the diameter of the outer surface 51 of the side wall 50.
これにより、化粧パネル２０をルーバーベース１８に装着する際に、ボス受け部２５と補助ボス受け部２６との間にボス部２３が挟まることはない。また、ルーバーベース１８に化粧パネル２０を正規に取り付けるときは、ボス部２３はボス受け部２５に容易に係合する。そして非正規、すなわち正しく取り付ける位置でない場合には、ボス部２３がボス受け部２５と補助ボス受け部２６とにぶつかって干渉することとなる。従って、ルーバーベース１８に化粧パネル２０を正規な位置に容易に取り付けることができる。
Thus, when the decorative panel 20 is mounted on the louver base 18, the boss portion 23 is not sandwiched between the boss receiving portion 25 and the auxiliary boss receiving portion 26. When the decorative panel 20 is properly attached to the louver base 18, the boss portion 23 easily engages with the boss receiving portion 25. If the position is not normal, i.e., not the correct mounting position, the boss portion 23 will hit the boss receiving portion 25 and the auxiliary boss receiving portion 26 and interfere with each other. Therefore, the decorative panel 20 can be easily attached to the louver base 18 at a regular position.
また、ボス部２３には化粧パネルの背面と接続する台座部４２ｂが設けられており、台座部４２ｂは、逆Ｕ字形状の端部が化粧パネルの背面に接続している。
Also, the boss portion 23 is provided with a pedestal portion 42b connected to the back surface of the decorative panel, and the pedestal portion 42b has an inverted U-shaped end connected to the back surface of the decorative panel.
これにより、ボス部２３の嵌合による円筒形状の歪が直接、化粧パネル２０に伝わることがなく、台座部４２ｂにて吸収されることになる。歪が直接化粧パネル２０に伝わると化粧パネル２０におけるユーザの目に曝される正面側に、この歪みが伝達して斑等が生じてしまい、美観が損なわれることがある。本発明に係る化粧パネル取付構造では、台座部４２ｂにて一旦歪みを吸収することにより、化粧パネル２０への嵌合や係合による影響を抑制することができる。
Thereby, the cylindrical distortion due to the fitting of the boss portion 23 is not directly transmitted to the decorative panel 20, but is absorbed by the pedestal portion 42b. When the distortion is directly transmitted to the decorative panel 20, the distortion is transmitted to the front side of the decorative panel 20 that is exposed to the eyes of the user, causing spots and the like, which may impair the beauty. In the decorative panel mounting structure according to the present invention, the influence due to fitting and engagement with the decorative panel 20 can be suppressed by once absorbing the distortion at the pedestal portion 42b.
本発明にかかる化粧パネル取付構造は、照明装置のカバーの取り付け構造等としても有用である。
The decorative panel mounting structure according to the present invention is also useful as a cover mounting structure for a lighting device.
