しかしながら、ボトム側の角隅部、トップ側の両側縁部にバンパーを取り付けたクラムシェル型の情報処理装置であっても、トップ側前面や側面を下にして床に当たった場合には、トップをボトムに対して開閉可能に支持するヒンジに衝撃が集中する。これにより、ヒンジ自体、ヒンジとの境目（トップ側、ボトム側）が壊れる可能性がある。   However, even if it is a clamshell type information processing device with bumpers attached to the corners on the bottom side and both side edges on the top side, if it hits the floor with the front side or side facing down, the top The impact concentrates on the hinge that supports the bottom so that it can be opened and closed. Thereby, the hinge itself and the boundary (top side, bottom side) with the hinge may be broken.

本発明は、上記に鑑みてなされたものであって、トップ側前面や側面を下にして床に当たった場合でも、トップ側からボトム側に衝撃が分散し、ヒンジ自体、ヒンジとの境目も壊れにくくなる情報処理装置を提供することを目的とする。   The present invention has been made in view of the above, and even when hitting the floor with the top side front side or side face down, the impact is dispersed from the top side to the bottom side, and the boundary between the hinge itself and the hinge is also present. An object of the present invention is to provide an information processing apparatus that is not easily broken.

上述した課題を解決し、目的を達成するために、本発明は、ボトムと、該ボトムに対して開閉可能に取り付けられたトップとを備えたクラムシェル型の情報処理装置において、前記トップの側面全周に前記トップの側面から外方に向けて突出するとともに、前記ボトムに対して前記トップを閉じた場合に、少なくとも前記ボトムの前面および両側面において被さるバンパーを設けたことを特徴とする。   In order to solve the above-described problems and achieve the object, the present invention provides a clamshell type information processing apparatus that includes a bottom and a top that can be opened and closed with respect to the bottom. A bumper is provided on the entire periphery that protrudes outward from the side surface of the top, and covers at least the front surface and both side surfaces of the bottom when the top is closed with respect to the bottom.

また、本発明は、上記発明において、前記ボトムに対して前記トップを開閉可能に取り付けるヒンジ軸をボトムに設けたことを特徴とする。   Moreover, the present invention is characterized in that, in the above-mentioned invention, a hinge shaft for attaching the top to the bottom so as to be opened and closed is provided on the bottom.

また、本発明は、上記発明において、前記バンパーが、前記ボトムに対して前記トップを閉じた場合に前記ボトムと前記トップとの間に挟まれる凸部を有することを特徴とする。   Moreover, the present invention is characterized in that, in the above invention, the bumper has a convex portion sandwiched between the bottom and the top when the top is closed with respect to the bottom.

本発明にかかる情報処理装置は、トップの側面全周にトップの側面から外方に向けて突出するとともに、ボトムに対してトップを閉じた場合に、少なくともボトムの前面および両側面において被さるバンパーを設けたので、トップ側前面や側面を下にして床に当たった場合でも、トップ側からボトム側に衝撃が分散し、ヒンジ自体、ヒンジとの境目も壊れにくくなる。   The information processing apparatus according to the present invention has a bumper that protrudes outward from the side surface of the top to the entire circumference of the side surface of the top, and covers at least the front surface and both side surfaces of the bottom when the top is closed with respect to the bottom. Since it is provided, even when it hits the floor with the top side front surface or side face down, the impact is dispersed from the top side to the bottom side, and the hinge itself and the boundary between the hinge are less likely to break.

以下に、本発明にかかる情報処理装置の実施の形態を図面に基づいて詳細に説明する。なお、この実施の形態によりこの発明が限定されるものではない。ここでは、ボトムと、ボトムに対して開閉可能に取り付けたトップとを有するクラムシェル型のノートパソコンを例に説明する。   Embodiments of an information processing apparatus according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments. Here, a clamshell notebook computer having a bottom and a top attached to the bottom so as to be opened and closed will be described as an example.

FIG. 2 is a rear view of the notebook computer shown in FIG. 1. 6 is a conceptual perspective view showing the configuration around the rubber bumper shown in FIG. 3, and FIG. 7 is a cross-sectional view showing the configuration around the rubber bumper shown in FIG.

図１に示すように、ノートパソコン１は、ボトム（本体）２と、ボトム２に対して開閉可能に取り付けたトップ（蓋体）３とを備えたクラムシェル型のものであり、トップ３を閉じた場合にボトム２と重なるように、ボトム２とトップ３とは、略同一の平面形状を有している。また、ボトム２には、ボトム２に対してトップ３を開閉可能に取り付けるヒンジ軸Ｏが設けてあり、トップ３の内側面(ボトム２に対してトップ３を閉じた場合に、ボトム２に対向する面)から内側（ボトム２側）に突出したヒンジ部３ａを回転可能に支持している（図５参照）。   As shown in FIG. 1, the notebook computer 1 is of a clamshell type having a bottom (main body) 2 and a top (lid body) 3 attached to the bottom 2 so as to be openable and closable. The bottom 2 and the top 3 have substantially the same planar shape so as to overlap with the bottom 2 when closed. Further, the bottom 2 is provided with a hinge shaft O for attaching the top 3 to the bottom 2 so that the top 3 can be opened and closed, and the inner surface of the top 3 (when the top 3 is closed with respect to the bottom 2, it faces the bottom 2. The hinge part 3a which protruded inward (bottom 2 side) from the (surface to perform) is supported rotatably (refer FIG. 5).

図７に示すように、トップ３は、フレーム３１と、フレーム３１に取り付けられた液晶表示器（ＬＣＤ）３２と、フレーム３１に取り付けられたデコレーションカバー３３とを備えて構成してある。フレーム３１は、液晶表示器３２を取り付けるための枠体であり、トップ３の内側となる部分（トップ３を閉じた場合にボトム２と対向する部分）に液晶表示器３２が取り付けられ、トップ３の外側となる部分にデコレーションカバー３３が取り付けられる。   As shown in FIG. 7, the top 3 includes a frame 31, a liquid crystal display (LCD) 32 attached to the frame 31, and a decoration cover 33 attached to the frame 31. The frame 31 is a frame for attaching the liquid crystal display 32, and the liquid crystal display 32 is attached to a portion inside the top 3 (a portion facing the bottom 2 when the top 3 is closed). The decoration cover 33 is attached to a portion that is outside the.

また、図１〜図７に示すように、トップ３を構成するフレーム３１の側面全周には、ラバーバンパー（バンパー）４が設けてある。ラバーバンパー４は、トップ３およびボトム２を衝撃から保護するためのもので、ボトム２に対してトップ３を閉じた状態でノートパソコン１を床に落とした場合に、最初にラバーバンパー４が当たるように、トップ３の側面から外方に向けて突出するように設けてある。   As shown in FIGS. 1 to 7, a rubber bumper (bumper) 4 is provided on the entire side surface of the frame 31 constituting the top 3. The rubber bumper 4 is for protecting the top 3 and the bottom 2 from impact. When the laptop computer 1 is dropped on the floor with the top 3 closed with respect to the bottom 2, the rubber bumper 4 first hits the rubber bumper 4. Thus, it is provided so as to protrude outward from the side surface of the top 3.

また、図６および図７に示すように、ラバーバンパー４の下縁部４ａは、ボトム２に対してトップ３を閉じた場合に、ボトム２の前面および両側面において被さるように、トップ３の内側面からボトム２側に突出して形成される。これにより、ボトム２に対してトップ３を閉じた状態でラバーバンパー４に衝撃が加わると、その衝撃は、トップ３とボトム２に分散して伝わることになる。したがって、トップ３の外周にのみラバーバンパーを設け、トップ３だけに衝撃が伝わる場合よりも衝撃が緩和することになり、ヒンジ軸Ｏに伝わる衝撃も緩和される。   Further, as shown in FIGS. 6 and 7, the lower edge 4 a of the rubber bumper 4 covers the front 3 and the both sides of the bottom 2 when the top 3 is closed with respect to the bottom 2. It is formed to protrude from the inner surface to the bottom 2 side. Thus, when an impact is applied to the rubber bumper 4 with the top 3 closed with respect to the bottom 2, the impact is distributed and transmitted to the top 3 and the bottom 2. Therefore, the rubber bumper is provided only on the outer periphery of the top 3, and the impact is mitigated as compared with the case where the impact is transmitted only to the top 3, and the impact transmitted to the hinge axis O is also reduced.

なお、ボトム２に対してトップ３を閉じた場合に、ボトム２の前面および両側面においてラバーバンパー４の下縁部４ａが被さる量は、１〜２ｍｍ程度であり、本実施の形態では、１．５ｍｍが重なるように、形成してある。   In addition, when the top 3 is closed with respect to the bottom 2, the amount of the lower edge 4a of the rubber bumper 4 on the front surface and both side surfaces of the bottom 2 is about 1 to 2 mm. It is formed so that 5 mm overlaps.

また、図７に示すように、ラバーバンパー４の内側面には、ボトム２に対してトップ３を閉じた場合にボトム２とトップ３との間に挟まれる凸部４ｂを有している。   Further, as shown in FIG. 7, the rubber bumper 4 has a convex portion 4 b that is sandwiched between the bottom 2 and the top 3 when the top 3 is closed with respect to the bottom 2.

このように構成されるラバーバンパー４は、衝撃を吸収するゴムで形成され、ＡＢＳ樹脂で形成されるフレーム３１と二色成形することにより、フレーム３１と一体に形成される。   The rubber bumper 4 configured as described above is formed of rubber that absorbs impact, and is formed integrally with the frame 31 by two-color molding with the frame 31 formed of ABS resin.

また、図７に示すように、液晶表示器３２の前面縁部には、枠３４が設けられる。枠３４は、液晶表示器３２の前面縁部を押さえるためのもので、これにより、液晶表示器３２のエッジ部分も覆い隠される。また、枠３４の前面には、スペーサラバー３５が設けてある。スペーサラバー３５は、ボトムに対してトップを閉じた場合に、ボトムとトップ（枠）との間に挟まり、上述したラバーバンパー４に形成した凸部４ｂとともに、ボトム２に対してトップ３を閉める時の衝撃を緩和する。また、スペーサラバー３５は、ラバーバンパー４に形成した凸部４ｂと一体に見えるように、ラバーバンパー４と同一の材質、同一のカラーで凸部４ｂとの間に隙間が生じないように取り付けられる。   As shown in FIG. 7, a frame 34 is provided at the front edge of the liquid crystal display 32. The frame 34 is used to hold the front edge of the liquid crystal display 32, so that the edge portion of the liquid crystal display 32 is also covered. A spacer rubber 35 is provided on the front surface of the frame 34. When the top is closed with respect to the bottom, the spacer rubber 35 is sandwiched between the bottom and the top (frame), and closes the top 3 with respect to the bottom 2 together with the convex portion 4b formed on the rubber bumper 4 described above. Reduce the impact of time. In addition, the spacer rubber 35 is attached so that a gap is not formed between the convex portion 4b with the same material and the same color as the rubber bumper 4 so that it can be seen integrally with the convex portion 4b formed on the rubber bumper 4. .

このように形成されるスペーサラバー３５は、ラバーバンパー４と同様、衝撃を吸収するゴムで形成され、ＡＢＳ樹脂で形成される枠３４と二色成形することにより、枠３４と一体に形成される。   Like the rubber bumper 4, the spacer rubber 35 formed in this way is formed of rubber that absorbs impact, and is formed integrally with the frame 34 by two-color molding with the frame 34 formed of ABS resin. .

上述した本発明の実施の形態であるノートパソコン１は、トップ３（フレーム３１）の側面外周にトップ３の側面から外方に向けて突出するとともに、ボトム２に対してトップ３を閉じた場合に、下縁部４ａがボトム２の前面および両側面において被さるラバーバンパー４を設けたので、トップ３側前面や側面を下に床に当たった場合でも、トップ３側からボトム２側に衝撃が分散し、ヒンジ自体、ヒンジとの境目も壊れにくくなる。   The above-described notebook personal computer 1 according to the embodiment of the present invention protrudes outward from the side surface of the top 3 on the outer periphery of the side surface of the top 3 (frame 31) and closes the top 3 with respect to the bottom 2 In addition, since the rubber bumper 4 is provided so that the lower edge 4a covers the front surface and both side surfaces of the bottom 2, even when the top 3 side front surface or side surface hits the floor, the impact is applied from the top 3 side to the bottom 2 side. Dispersed, and the hinge itself and the boundary with the hinge are not easily broken.

また、ボトム２に対してトップ３を閉じた場合に、ラバーバンパー４の下縁部４ａがボトム２の前面および両側面において被さるので、ノートパソコン１を持ち運ぶ場合にも、ボトム２とトップ３とが当たることにより生じる音（カタカタ音）を抑制できる。さらに、ホコリの侵入抑制の効果も期待できる。   Further, when the top 3 is closed with respect to the bottom 2, the bottom edge 4 a of the rubber bumper 4 is covered on the front surface and both side surfaces of the bottom 2. It is possible to suppress the sound generated by hitting (a rattling sound). Furthermore, the effect of suppressing dust intrusion can be expected.

また、ボトム２に対してトップ３を開閉可能に取り付けるヒンジ軸Ｏをボトム２に設けたので、本実施の形態のように、トップ３の側面全周にラバーバンパー４を設けても、トップ３が厚くならない。   Further, since the hinge shaft O for attaching the top 3 to the bottom 2 so as to be opened and closed is provided on the bottom 2, even if the rubber bumper 4 is provided on the entire side surface of the top 3 as in the present embodiment, the top 3 Does not get thicker.

さらに、ラバーバンパー４が、ボトム２に対してトップ３を閉じた場合に、ボトム２とトップ３との間に挟まれる凸部４ｂを有するので、ボトム２に対してトップ３を閉じた場合に衝撃を抑制する。これにより、ボトム２に対してトップ３を閉じる場合に生じる音（開閉音）も抑制される。   Further, when the rubber bumper 4 has the convex portion 4b sandwiched between the bottom 2 and the top 3 when the top 3 is closed with respect to the bottom 2, the rubber bumper 4 has a convex portion 4b sandwiched between the bottom 2 and the top 3. Suppresses impact. Thereby, the sound (opening / closing sound) generated when the top 3 is closed with respect to the bottom 2 is also suppressed.

なお、上述した実施の形態であるノートパソコン１では、ラバーバンパー４の下縁部４ａがボトム２の前面および両側面において被さるとし、ラバーバンパー４の下縁部４ａがボトム２の背面において被さるか否かに言及していないが、ラバーバンパー４の下縁部４ａがボトム２の背面において被さるように構成してもよいし、被さらないように構成してもよい。これは、ヒンジ軸Ｏ側を下に床に当たってもヒンジ軸Ｏに加わるモーメントが小さいと考えられること、ボトム２の背面側にヒンジ軸Ｏが設けられ、ヒンジ軸Ｏ側（ボトムの背面側）において、ボトム２に対してトップ３が開閉されないこと、ヒンジ軸Ｏ側を上に持ち運ぶので、ヒンジ軸Ｏ側を下に床に当たる可能性小さいこと、等を考慮したものである。   In the notebook computer 1 according to the embodiment described above, the lower edge 4a of the rubber bumper 4 is covered on the front surface and both side surfaces of the bottom 2, and the lower edge 4a of the rubber bumper 4 is covered on the rear surface of the bottom 2. Although not mentioned whether or not, the lower edge 4a of the rubber bumper 4 may be configured to be covered on the back surface of the bottom 2, or may be configured not to be covered. This is because the moment applied to the hinge axis O is considered to be small even if it hits the floor with the hinge axis O side down, the hinge axis O is provided on the back side of the bottom 2, and on the hinge axis O side (the back side of the bottom) Considering that the top 3 is not opened and closed with respect to the bottom 2 and that the hinge axis O side is carried upward, the possibility that the hinge axis O side will hit the floor down is small.

また、ヒンジ軸Ｏをボトム２に設けることとしたが、ヒンジ軸Ｏをトップ３に設けることとしてもよい。   Further, although the hinge axis O is provided on the bottom 2, the hinge axis O may be provided on the top 3.
