Description

この発明は、パネルユニットに取り付けられる化粧パネルに関する。   The present invention relates to a decorative panel attached to a panel unit.

火災受信機、消火システム制御盤等には、液晶パネルが搭載されたパネルユニットが扉に取り付けられている。このようなパネルユニットの取付方法の一例としては、筐体に設けた開口部に対して、パネルユニットを、筐体の正面側から嵌め込むようにして取り付けたものがある（例えば、特許文献１参照）。   A panel unit equipped with a liquid crystal panel is attached to a door of a fire receiver, a fire extinguishing system control panel, or the like. As an example of such a panel unit mounting method, there is a method in which a panel unit is mounted so as to be fitted into an opening provided in a housing from the front side of the housing (for example, see Patent Document 1). .

従来、液晶パネルの固定枠に貼り付ける化粧パネルは、厚みのある主部と、主部の上辺に設けられ、パネルユニットに差し込まれるリブと、により構成されている。ここで、リブの長さは、化粧パネルの上辺と同じ長さとして形成されている。   2. Description of the Related Art Conventionally, a decorative panel to be attached to a fixed frame of a liquid crystal panel includes a thick main part and a rib provided on an upper side of the main part and inserted into a panel unit. Here, the length of the rib is formed as the same length as the upper side of the decorative panel.

特開平７−２７４３１７号公報JP-A-7-274317

しかしながら、化粧パネルは、主部の板厚と、リブの板厚とが異なっている。具体的には、リブの板厚は、主部の板厚よりも薄く形成されている。このため、成形工程の冷却時に、化粧パネルの材料が冷え固まるまでの時間が、主部とリブとで異なる。化粧パネルの材料であるアクリルは、固まる際に収縮する。このため、リブが固まった後も、リブよりも厚みのある主部は、さらに収縮することになる。   However, in the decorative panel, the thickness of the main portion and the thickness of the rib are different. Specifically, the thickness of the rib is formed smaller than the thickness of the main part. For this reason, at the time of cooling in the molding process, the time required for the material of the decorative panel to cool and harden differs between the main portion and the rib. Acrylic, the material of the decorative panel, shrinks when it hardens. For this reason, even after the ribs are hardened, the main part having a greater thickness than the ribs further contracts.

この結果、主部にゆがみが生じ、反りが発生することとなる。特に、液晶パネルのサイズが大きくなった場合には、反りの発生に起因するゆがみの問題が、より顕著となり、ゆがみ量を極力抑制することが望まれている。   As a result, the main part is distorted, and warpage occurs. In particular, when the size of the liquid crystal panel increases, the problem of distortion due to the occurrence of warpage becomes more remarkable, and it is desired to minimize the amount of distortion.

本発明は、このような問題を解決するためになされたものであり、成形工程の冷却時に、リブの硬化後に収縮が続く主部のゆがみ量を抑制することができる化粧パネルを得ることを目的とする。   The present invention has been made in order to solve such a problem, and it is an object of the present invention to provide a decorative panel capable of suppressing the amount of distortion of a main portion that continues to shrink after curing of a rib during cooling in a molding process. And

上記の課題を解決するために、本発明に係る化粧パネルは、主部と、主部の外周辺に配置されたリブと、を有して構成される化粧パネルであって、リブの板厚は、主部の板厚よりも薄く、リブは、外周辺において、複数に分割されて配置されているものである。   In order to solve the above-mentioned problem, a decorative panel according to the present invention is a decorative panel including a main part and a rib disposed on an outer periphery of the main part, wherein the thickness of the rib is Is thinner than the plate thickness of the main part, and the rib is divided into a plurality of parts on the outer periphery.

この発明によれば、化粧パネルに設けられるリブを、複数に分割して形成する構成を備えている。この結果、成形工程の冷却時に、リブの硬化後に収縮が続く主部のゆがみ量を抑制することができる化粧パネルを得ることができる。   According to the present invention, a configuration is provided in which the rib provided on the decorative panel is divided into a plurality of parts. As a result, it is possible to obtain a decorative panel capable of suppressing the amount of distortion of the main portion that continues to shrink after the ribs are hardened during the cooling in the molding step.

The operation unit 20 is provided with a touch key 21 and a makeup panel 22 that can be operated by a user while viewing the display contents of the liquid crystal panel 31. Although the touch keys 21 and the makeup panel 22 are omitted in FIG. 1, they will be described in detail with reference to FIGS.

また、以下の説明において、火災受信機１の本体２に対してパネルユニット１０が取り付けられている側を正面側Ｘ１とし、正面側Ｘ１の反対側を裏面側Ｘ２とする。   In the following description, the side where the panel unit 10 is attached to the main body 2 of the fire receiver 1 is referred to as a front side X1, and the opposite side of the front side X1 is referred to as a back side X2.

本実施の形態１に係る化粧パネル２２は、リブの配置および形状を工夫することで、成形工程の冷却時において発生する主部のゆがみ量を抑制することを技術的特徴としている。そこで、この技術的特徴に関する具体的な構成について、図２、図３を用いて詳細に説明する。   The technical feature of the decorative panel 22 according to the first embodiment is that the arrangement and shape of the ribs are devised to suppress the amount of distortion of the main part that occurs during cooling in the forming process. Therefore, a specific configuration related to this technical feature will be described in detail with reference to FIGS.

図２は、本発明の実施の形態１に係るパネルユニット１０において、化粧パネル２２を固定枠１１に取り付ける様子を示した説明図である。また、図３は、本発明の実施の形態１に係る化粧パネル２２の形状を示す説明図である。図３（ａ）は、化粧パネル２２の上面図、図３（ｂ）は、化粧パネル２２の正面図、図３（ｃ）は、化粧パネル２２の下面図をそれぞれ示している。   FIG. 2 is an explanatory diagram showing a state where the decorative panel 22 is attached to the fixed frame 11 in the panel unit 10 according to Embodiment 1 of the present invention. FIG. 3 is an explanatory diagram showing the shape of the decorative panel 22 according to Embodiment 1 of the present invention. 3A is a top view of the decorative panel 22, FIG. 3B is a front view of the decorative panel 22, and FIG. 3C is a bottom view of the decorative panel 22, respectively.

図２に示すように、化粧パネル２２は、正面側Ｘ１から裏面側Ｘ２の方向で、固定枠１１に取り付けられることで、タッチキー２１が設けられた操作部２０の前面を覆う状態となる。このような化粧パネル２２の取り付けの際には、化粧パネル２２の上部に設けられた複数のリブ２４が、固定枠１１に差し込まれることとなる。   As shown in FIG. 2, the decorative panel 22 is attached to the fixed frame 11 in a direction from the front side X1 to the back side X2, so that the decorative panel 22 covers the front surface of the operation unit 20 provided with the touch keys 21. When such a decorative panel 22 is attached, a plurality of ribs 24 provided on the upper part of the decorative panel 22 are inserted into the fixed frame 11.

本実施の形態１に係る化粧パネル２２は、図３に示すように、主部２３と、上部に設けられた複数のリブ２４と、左右に設けられた複数のリブ２５と、下部に設けられた複数のリブ２６と、を有して構成されている。ここで、上部に設けられた複数のリブ２４は、固定枠１１に対して化粧パネル２２を取り付ける際に利用される。   As shown in FIG. 3, the decorative panel 22 according to the first embodiment includes a main portion 23, a plurality of ribs 24 provided on an upper portion, a plurality of ribs 25 provided on left and right, and provided on a lower portion. And a plurality of ribs 26. Here, the plurality of ribs 24 provided on the upper portion are used when attaching the decorative panel 22 to the fixed frame 11.

一方、その他のリブ２５、２６は、化粧パネル２２が固定枠１１に取り付けられた後のパネルユニット１０を、扉３の開口部３ａに裏面側から取り付ける際に利用される。すなわち、リブ２５、２６は、扉３の裏面により固定枠１１に押し付けられる形となる。このようにして、リブ２４〜２６を利用することで、販売後におけるパネルユニット１０の温度変化等による反りを抑制することができる。   On the other hand, the other ribs 25 and 26 are used when attaching the panel unit 10 after the decorative panel 22 is attached to the fixed frame 11 to the opening 3 a of the door 3 from the back side. That is, the ribs 25 and 26 are pressed against the fixed frame 11 by the back surface of the door 3. By using the ribs 24 to 26 in this way, it is possible to suppress warpage due to a temperature change or the like of the panel unit 10 after sale.

なお、図２、図３に示したように、化粧パネル２２は、一般的に矩形形状を有している。そして、矩形形状の外周辺のうち、上辺に設けられた複数のリブ２４は、第１リブに相当する。また、矩形形状の外周辺のうち、上辺以外に設けられた複数のリブ２５、２６は、第２リブに相当する。   Note that, as shown in FIGS. 2 and 3, the decorative panel 22 has a generally rectangular shape. The plurality of ribs 24 provided on the upper side of the outer periphery of the rectangular shape correspond to the first ribs. The plurality of ribs 25 and 26 provided on the outer periphery of the rectangular shape other than the upper side correspond to the second ribs.

リブ２４〜２６の板厚は、主部２３の板厚よりも薄く形成される。従って、成形工程の冷却時に、リブ２４〜２６が固まった後も、リブよりも厚みのある主部２３は、さらに収縮することになる。従来は、リブ２４〜２６が、化粧パネル２２の各外周辺に沿って、それぞれの辺と同じ長さで形成されていた。この場合には、成形工程の冷却時に、主部２３にゆがみが生じ、反りが発生する問題があった。   The plate thickness of the ribs 24 to 26 is formed smaller than the plate thickness of the main portion 23. Therefore, even after the ribs 24 to 26 are solidified during the cooling in the forming step, the main part 23 having a thickness larger than the ribs is further contracted. Conventionally, the ribs 24 to 26 are formed along the outer periphery of the decorative panel 22 with the same length as each side. In this case, there is a problem that the main portion 23 is warped during the cooling in the forming step, and warpage occurs.

これに対して、本実施の形態１では、化粧パネル２２の各辺に設けるリブが複数に分割されており、それぞれの辺において、複数のリブが複数の固定片として機能するように配置されている。このように、リブ２４〜２６のそれぞれを、複数の固定片に分割することで、成形工程の冷却時に発生する主部２３の反りを抑制することができる。すなわち、各辺のリブを複数に分割することで、成形工程の冷却時に、複数のリブ２４〜２６が硬化した後に続く主部２３のゆがみを抑制することができる。   On the other hand, in the first embodiment, the rib provided on each side of the decorative panel 22 is divided into a plurality of parts, and on each side, the plurality of ribs are arranged so as to function as a plurality of fixing pieces. I have. As described above, by dividing each of the ribs 24 to 26 into a plurality of fixed pieces, it is possible to suppress the warpage of the main portion 23 that occurs at the time of cooling in the forming process. That is, by dividing the rib on each side into a plurality of parts, it is possible to suppress the distortion of the main part 23 following the curing of the plurality of ribs 24 to 26 at the time of cooling in the molding process.

以上のように、実施の形態１によれば、化粧パネルに設けられるリブを、各辺で複数に分割して形成している。この結果、成形工程の冷却時に、複数に分割されたリブの硬化後に収縮が続く主部にゆがみが発生することを抑制することができる。   As described above, according to the first embodiment, the rib provided on the decorative panel is divided into a plurality of parts on each side. As a result, at the time of cooling in the molding step, it is possible to suppress the occurrence of distortion in the main portion that continues to shrink after the plurality of divided ribs are cured.

なお、リブに関しては、すべての辺のリブを複数に分割する必要はなく、例えば、固定枠１１に差し込まれるリブ２４を分割配置することで、主部２３に発生するゆがみ量を抑制することができる。   It is not necessary to divide the ribs on all sides into a plurality of ribs. For example, by arranging the ribs 24 inserted in the fixed frame 11 separately, the amount of distortion generated in the main portion 23 can be suppressed. it can.
