FIG. However, unless there is a specific description, the configuration described in this embodiment is not intended to limit the scope of the present invention, but is merely an example of explanation.

〔電気機器の構成〕
本実施形態に係る電気機器の構成について説明する。以下、一例として、電気機器は、表示パネルを備える表示装置であるものとして説明するが、これに限定されず、例えばゲーム機や、パソコン等の他の機器であってもよい。 [Configuration of electrical equipment]
The configuration of the electrical equipment according to this embodiment will be described. Hereinafter, as an example, the electric device will be described as a display device having a display panel, but it is not limited to this, and may be other devices such as a game machine or a personal computer.

図１は、本実施形態に係る表示装置における、前面を除く筐体３の内部を示す斜視図である。筐体３は、１又は複数の所定の領域のそれぞれに複数の第１の通気孔５を有している。また、筐体３には、前記所定の領域のそれぞれに重畳するように、複数の第２の通気孔６を有する板状部材７がスライド可能に取り付けられている。 FIG. 1 is a perspective view showing the inside of a housing 3, excluding the front surface, in a display device according to this embodiment. The housing 3 has a plurality of first vent holes 5 in each of one or more predetermined regions. A plate member 7 having a plurality of second air holes 6 is slidably attached to the housing 3 so as to overlap each of the predetermined regions.

図２は、筐体３が有する第１の通気孔５、及び第２の通気孔６を有する板状部材７の一例を示す図である。図２において、説明図８ａと説明図８ｂとは、表示パネルが横長又は縦長になるように筐体３を配置した場合に、筐体３の上下の側面部と左右の側面部とに位置する第１の通気孔５の向きをそれぞれ示している。また、説明図８ｃと説明図８ｃとは、表示パネルが横長又は縦長になるように筐体３を配置した場合に、筐体３の上下の側面部と左右の側面部に位置する板状部材７の向きをそれぞれ示している。また、図２に示すように、筐体３が有する第１の通気孔５と板状部材７が有する第２の通気孔６との形状及び配置は同一である。 FIG. 2 is a diagram showing an example of the plate member 7 having the first ventilation hole 5 and the second ventilation hole 6 of the housing 3. As shown in FIG. In FIG. 2, explanatory diagrams 8a and 8b are located on the upper and lower side parts and the left and right side parts of the housing 3 when the housing 3 is arranged so that the display panel is horizontally long or vertically long. The directions of the first air holes 5 are shown respectively. 8c and 8c show plate-like members positioned on the upper and lower side portions and the left and right side portions of the housing 3 when the housing 3 is arranged such that the display panel is horizontally long or vertically long. 7, respectively. Further, as shown in FIG. 2, the shape and arrangement of the first ventilation hole 5 of the housing 3 and the second ventilation hole 6 of the plate member 7 are the same.

図３は、筐体３内部に板状部材７を取り付ける工程の一例を示す図である。図３の説明図１０ａに示すように、筐体３内部の通気孔の周囲には、断面がＬ字状の突起が４箇所設けられている。また、このＬ字状の突起を、以下「Ｌ型部材９」と呼称することもある。 3A and 3B are diagrams showing an example of a process of attaching the plate member 7 inside the housing 3. FIG. As shown in the explanatory diagram 10a of FIG. 3, four projections having an L-shaped cross section are provided around the ventilation hole inside the housing 3. As shown in FIG. Moreover, this L-shaped protrusion may be hereinafter referred to as an "L-shaped member 9".

続いて、説明図１０ｂに示すように各Ｌ型部材９の内側に板状部材７を挿入することで板状部材７を筐体３内部に取り付ける。続いて、Ｌ型部材９と接触していない一対の辺にガイド部材１１を差し込む。これにより、板状部材７が通気孔の内側から外れることを抑制できる。 Subsequently, as shown in an explanatory diagram 10b, the plate-like member 7 is attached inside the housing 3 by inserting the plate-like member 7 inside each L-shaped member 9 . Subsequently, the guide member 11 is inserted into the pair of sides that are not in contact with the L-shaped member 9. As shown in FIG. As a result, it is possible to prevent the plate-like member 7 from coming off the inside of the ventilation hole.

なお、板状部材７を通気孔の内側に取り付ける手順は、図３に示す手順に限定されない。例えば、板状部材７が可撓性を有する素材である場合、筐体３に対してＬ型部材９およびガイド部材１１を先に設け、後から板状部材７を折り曲げつつ取り付ける手順であってもよい。 Note that the procedure for attaching the plate member 7 to the inside of the vent hole is not limited to the procedure shown in FIG. For example, if the plate-like member 7 is made of a flexible material, the L-shaped member 9 and the guide member 11 are first provided to the housing 3, and then the plate-like member 7 is attached while being bent. good too.

図４において、説明図１２ａ～１２ｅは、Ｌ型部材９およびガイド部材１１に囲まれた領域において板状部材７が重力の作用によってスライドする様子を示している。また、説明図１２ａ～１２ｅにおいては、鉛直下方向（紙面下方向）が重力方向であり、また、楕円はＬ型部材９と板状部材７との隙間を表している。 In FIG. 4, explanatory diagrams 12a to 12e show how the plate member 7 slides under the action of gravity in the area surrounded by the L-shaped member 9 and the guide member 11. As shown in FIG. 12a to 12e, the vertical downward direction (downward direction on the paper surface) is the direction of gravity, and the ellipse represents the gap between the L-shaped member 9 and the plate member 7. As shown in FIG.

説明図１２ａにおいて、板状部材７は、下方に偏っており、また、筐体３の第１の通気孔５と板状部材７の第２の通気孔６とは連通している。即ち、当該第１の通気孔５は、板状部材７によって塞がれてはおらず、空気の出入りが可能な状態である。 12a, the plate-like member 7 is biased downward, and the first ventilation hole 5 of the housing 3 and the second ventilation hole 6 of the plate-like member 7 are in communication. That is, the first ventilation hole 5 is not blocked by the plate-like member 7 and is in a state in which air can enter and exit.

説明図１２ｂは、説明図１２ａに示す状態から、筐体３ごと各部材を９０度左に回転させた直後の状態を示している。そして重力が下方向に作用しているので、板状部材７は、ガイド部材１１に沿って左下方向にスライドし、説明図１２ｃに示す状態に遷移する。 Explanatory drawing 12b shows a state immediately after each member is rotated counterclockwise by 90 degrees together with housing 3 from the state shown in explanatory drawing 12a. Since gravity acts downward, the plate-like member 7 slides leftward and downward along the guide member 11, and transitions to the state shown in FIG. 12c.

説明図１２ｃの状態において、筐体３の第１通気孔と板状部材７の第２の通気孔６とは連通していない。即ち、当該第１の通気孔５は、板状部材７によって塞がれている状態である。また、説明図１２ｂ及び１２ｃにおいて、板状部材７に対して作用する重力の方向は、本開示における第２の向きの一例である。 In the state of explanatory drawing 12c, the first ventilation hole of the housing 3 and the second ventilation hole 6 of the plate member 7 are not communicated. That is, the first air hole 5 is in a state of being blocked by the plate member 7 . Also, in explanatory diagrams 12b and 12c, the direction of gravity acting on the plate member 7 is an example of the second direction in the present disclosure.

説明図１２ｄは、説明図１２ｃに示す状態から、筐体３ごと各部材を９０度右に回転させた直後の状態を示している。そして重力が下方向に作用しているので、板状部材７は、ガイド部材１１に沿って右下方向にスライドし、説明図１２ｅに示す状態に遷移する。 Explanatory drawing 12d shows a state immediately after each member is rotated to the right by 90 degrees together with housing 3 from the state shown in explanatory drawing 12c. Since gravity acts downward, the plate member 7 slides downward and to the right along the guide member 11, and transitions to the state shown in FIG. 12e.

説明図１２ｅに示す状態は、説明図１２ａに示す状態に等しく、筐体３の第１の通気孔５と板状部材７の第２の通気孔６とは連通している。また、説明図１２ｄ及び１２ｅにおいて、板状部材７に対して作用する重力の方向は、本開示における第１の向きの一例である。板状部材７を基準にした場合、上記第１の向きは、第２の向きとは異なっている。 The state shown in FIG. 12e is equivalent to the state shown in FIG. 12a, and the first vent hole 5 of the housing 3 and the second vent hole 6 of the plate-like member 7 are in communication. Also, in explanatory diagrams 12d and 12e, the direction of gravity acting on the plate member 7 is an example of the first direction in the present disclosure. When the plate member 7 is used as a reference, the first orientation is different from the second orientation.

また、板状部材７が筐体３の第１の通気孔５を塞がない位置であって、説明図１２ａ、１２ｂ及び１２ｅに示す板状部材７の位置は、本開示における第１の位置の一例である。また、板状部材７が筐体３の第１の通気孔５を塞ぐ位置であって、説明図１２ｃ及び１２ｄに示す板状部材７の位置は、本開示における第２の位置の一例である。 In addition, the position where the plate-like member 7 does not block the first ventilation hole 5 of the housing 3, and the position of the plate-like member 7 shown in explanatory drawings 12a, 12b, and 12e is the first position in the present disclosure. is an example. Further, the position where the plate-like member 7 closes the first ventilation hole 5 of the housing 3, and the position of the plate-like member 7 shown in explanatory drawings 12c and 12d is an example of the second position in the present disclosure. .

上述したように、板状部材７は、重力の作用により、重力の向きに非平行な方向にガイド部材１１に沿ってスライドすることによって、第１の位置、又は第２の位置に配置され得る。また、板状部材７は、第１の向き及び第２の向きの双方に対して平行でもなく垂直でもない一対の辺を有し、平行四辺形またはそれに準ずる形状をしていてもよく、表示装置の筐体３は、前記一対の辺のそれぞれをガイドする一対のガイド部材１１を備えていてもよい。 As described above, the plate member 7 can be placed in the first position or the second position by sliding along the guide member 11 in a direction non-parallel to the direction of gravity under the action of gravity. . In addition, the plate-like member 7 may have a pair of sides that are neither parallel nor perpendicular to both the first direction and the second direction, and may have a parallelogram or a similar shape. The housing 3 of the apparatus may include a pair of guide members 11 that guide the pair of sides, respectively.

また、図１に示す筐体３を有する表示装置であって、電気機器の一種である本実施形態に係る表示装置は、表示パネルを備え、筐体３は、前記表示パネルの４つの側面の各々を覆う側面部を備えており、前記各側面部の法線方向は前記表示パネルの法線方向と垂直ではなく、各板状部材７が、前記各側面部において少なくとも１箇所以上配置されている構成である。 Further, the display device having the housing 3 shown in FIG. 1 according to the present embodiment, which is a type of electrical equipment, includes a display panel, and the housing 3 is provided on four sides of the display panel. A side surface portion covering each side surface is provided, the normal direction of each side surface portion is not perpendicular to the normal direction of the display panel, and each plate-like member 7 is arranged at least one place on each side surface portion. configuration.

より具体的には、図１に示す筐体３を有する表示装置においては、表示パネルが設けられる前面の面積の方が背面の面積よりも大きく、前面の各辺の長さが対応する背面の各辺よりも長い。これにより、筐体３の向かい合う２対の側面部同士は互いに平行ではなく、表示装置を平坦な床の上に設置したとしても、何れの側面も床に平行とはならない。別の観点から言えば、筐体３の側面部に取り付けられた板状部材７は、何れも当該板状部材７の主面の法線方向とは異なる方向に重力の作用を受けることを意味している。 More specifically, in the display device having the housing 3 shown in FIG. 1, the area of the front surface where the display panel is provided is larger than the area of the back surface, and the length of each side of the front surface corresponds to the length of the back surface. longer than each side. As a result, the two pairs of side surfaces facing each other of the housing 3 are not parallel to each other, and even if the display device is placed on a flat floor, neither side surface is parallel to the floor. From another point of view, each of the plate-like members 7 attached to the side surface of the housing 3 receives the action of gravity in a direction different from the normal direction of the main surface of the plate-like member 7. are doing.

これにより、例えば表示装置がピボット機能を有する場合において、表示パネルが横長又は縦長になるように筐体３を配置した場合、筐体３の上下の側面部に位置する板状部材７は、対応する第１の通気孔５を塞がない第１の位置にスライドし、且つ筐体３の左右の側面部に位置する板状部材７は、対応する第１の通気孔５を塞ぐ第２の位置にスライドするという構成が実現される。また、当該構成において、筐体３の左右の側面部に位置する板状部材７は、当該板状部材７の主面が第２の向きと平行になるように配置されている、と言える。 As a result, for example, in the case where the display device has a pivot function, when the housing 3 is arranged so that the display panel is horizontally long or vertically long, the plate members 7 positioned on the upper and lower side portions of the housing 3 do not correspond to each other. The plate-like members 7 that slide to the first position that does not block the first ventilation holes 5 and that are located on the left and right side surfaces of the housing 3 are second openings that block the corresponding first ventilation holes 5. A configuration is realized that slides into position. Further, in this configuration, it can be said that the plate-like members 7 positioned on the left and right side surfaces of the housing 3 are arranged such that the main surfaces of the plate-like members 7 are parallel to the second direction.

上述した例のように、本実施形態に係る電気機器は、１又は複数の所定の領域のそれぞれに複数の第１の通気孔５を有する筐体３と、複数の第２の通気孔６を有し、各領域に重畳するように筐体３にスライド可能に取り付けられた板状部材７とを備え、板状部材７は、当該板状部材７に対して重力が第１の向きに作用した場合に、当該重力の作用により、第１の通気孔５の少なくとも一部と第２の通気孔６とが連通する状態となる第１の位置に配置され、当該板状部材７に対して重力が第１の向きとは異なる第２の向きに作用した場合に、当該重力の作用により、第１の通気孔５と第２の通気孔６とが連通しない状態となる第２の位置に配置される構成である。上記の構成によれば、設置する向きに応じて開閉する複数の通気孔を、少ない部品点数によって電気機器に設けることができる。 As in the example described above, the electrical device according to this embodiment includes a housing 3 having a plurality of first ventilation holes 5 in each of one or a plurality of predetermined regions, and a plurality of second ventilation holes 6. and a plate-like member 7 slidably attached to the housing 3 so as to overlap each region, and the plate-like member 7 exerts gravity on the plate-like member 7 in a first direction. In this case, the plate-like member 7 is arranged at a first position where at least a part of the first ventilation hole 5 and the second ventilation hole 6 are in communication with each other due to the action of gravity. When gravity acts in a second direction different from the first direction, the action of gravity causes the first vent hole 5 and the second vent hole 6 to be in a state of not communicating with each other. It is a configuration to be arranged. According to the above configuration, it is possible to provide the electric device with a plurality of ventilation holes that open and close according to the installation direction with a small number of parts.

〔変形例１〕
上記実施形態の第１の変形例について、以下に説明する。なお、説明の便宜上、上記実施形態にて説明した部材と同じ機能を有する部材については、同じ符号を付記し、重複する説明を繰り返さない。また、以降の変形例においても同様である。本変形例においては、板状部材７に、当該板状部材７を筐体３内部に取り付けるためのガイド孔１３が設けられている構成の一例について説明する。 [Modification 1]
A first modification of the above embodiment will be described below. For convenience of description, members having the same functions as those of the members described in the above embodiments are denoted by the same reference numerals, and overlapping descriptions will not be repeated. Further, the same applies to subsequent modifications. In this modified example, an example of a configuration in which the plate-like member 7 is provided with a guide hole 13 for mounting the plate-like member 7 inside the housing 3 will be described.

図５において、説明図１４ａ～１４ｃは、筐体３内部に本変形例に係る板状部材７を取り付ける工程の一例を示す図である。 In FIG. 5, explanatory diagrams 14a to 14c are diagrams showing an example of the process of attaching the plate-like member 7 according to this modified example inside the housing 3. As shown in FIG.

説明図１４ａに示すように、本変形例に係る筐体３の通気孔の周囲には、上述したＬ型部材９は特に設けられずともよい。また、説明図１４ｂに示すように、本変形例に係る板状部材７には、第１の向きおよび第２の向きの双方に対して平行でもなく垂直でもない一対のガイド孔１３が設けられている。また、説明図１４ｃは、ガイド孔１３のそれぞれに貫入するガイド部材１１を差し込んだ状態を示している。 As shown in an explanatory diagram 14a, the above-described L-shaped member 9 may not be particularly provided around the ventilation hole of the housing 3 according to this modification. Further, as shown in an explanatory diagram 14b, the plate member 7 according to this modification is provided with a pair of guide holes 13 that are neither parallel nor perpendicular to both the first direction and the second direction. ing. 14c shows a state in which the guide members 11 are inserted into the respective guide holes 13. FIG.

説明図１４ｃに示す状態において、板状部材７は、筐体３内部に取り付けられ、ガイド孔１３に応じた領域内をスライドすることが可能である。これにより、上記実施形態と同様に、板状部材７に対して重力が第１の向きに作用した場合、板状部材７が第１の位置にスライドして、筐体３の第１の通気孔５と板状部材７の第２の通気孔６とは連通し、板状部材７に対して重力が第２の向きに作用した場合、板状部材７が第２の位置にスライドして、第１の通気孔５と第２の通気孔６とは連通しない構成が実現される。本変形例の構成によれば、筐体３にＬ型部材９を設けずとも、上記実施形態と同様な効果を奏する。 In the state shown in the explanatory diagram 14c, the plate-like member 7 is attached inside the housing 3 and can slide within the area corresponding to the guide hole 13. As shown in FIG. As a result, as in the above embodiment, when gravity acts on the plate-like member 7 in the first direction, the plate-like member 7 slides to the first position, thereby allowing the housing 3 to move in the first direction. The pores 5 communicate with the second ventilation holes 6 of the plate-like member 7, and when gravity acts on the plate-like member 7 in the second direction, the plate-like member 7 slides to the second position. , the first ventilation hole 5 and the second ventilation hole 6 do not communicate with each other. According to the configuration of this modified example, even if the housing 3 is not provided with the L-shaped member 9, the same effects as those of the above-described embodiment can be obtained.

〔変形例２〕
上記実施形態の第２の変形例について説明する。本変形例においては、ガイド部材がローラー状の部品を有する構成の一例について説明する。 [Modification 2]
A second modification of the above embodiment will be described. In this modified example, an example of a configuration in which the guide member has a roller-shaped component will be described.

図６は、本変形例に係るガイド部材１１の一例を示している。図６に示すように、本変形例に係るガイド部材１１は、ガイドポール１５と、ローラー（ワッシャー、ベアリング）１７とを備えている。ただし、図６のガイドポール１５においては、ネジの頭部に相当する箇所の図示が省略されている。当該箇所は、ローラー１７がガイドポール１５から欠落しないために、ローラー１７の内径よりも大きいサイズであることが要求される。 FIG. 6 shows an example of the guide member 11 according to this modified example. As shown in FIG. 6 , the guide member 11 according to this modification includes a guide pole 15 and rollers (washers, bearings) 17 . However, in the guide pole 15 of FIG. 6, illustration of a portion corresponding to the head of the screw is omitted. In order for the roller 17 not to drop off from the guide pole 15 , the portion is required to have a size larger than the inner diameter of the roller 17 .

また、ガイドポール１５及びローラー１７には、例えばポリアセタール（ＰＯＭ）、ポリアミド（ＰＡ）又はポリテトラフルオロエチレン（ＰＴＦＥ）等の摺動特性に優れた素材を用いることが望ましい。これにより、板状部材７がスライドする際の摩擦音や振動を軽減することができる。 Also, for the guide pole 15 and roller 17, it is desirable to use a material having excellent sliding properties, such as polyacetal (POM), polyamide (PA), or polytetrafluoroethylene (PTFE). As a result, it is possible to reduce frictional noise and vibration when the plate member 7 slides.
