以下、本発明の実施形態について図面を参照して説明する。
図１に示す什器１Ａは、執務室等で用いられるオフィス収納（キャビネット）である。什器１Ａは、床上に載置される直方体形状の筐体２と、筐体２の前面開口を開閉する複数の開閉体３と、を備える。各開閉体３は、什器１Ａにおける垂直な前面に沿う板状をなし、前面視で水平方向に長い長方形状に形成される。以下、前面視の水平方向を左右方向とする。各開閉体３は、図１に示す例では上下三段に並んで設けられる。 Embodiments of the present invention will be described below with reference to the drawings.
A fixture 1A shown in FIG. 1 is an office storage (cabinet) used in an office or the like. The fixture 1 </ b> A includes a rectangular parallelepiped housing 2 placed on the floor and a plurality of opening / closing bodies 3 that open and close the front opening of the housing 2. Each open / close body 3 has a plate shape along a vertical front surface in the fixture 1A, and is formed in a rectangular shape that is long in the horizontal direction when viewed from the front. Hereinafter, the horizontal direction in front view is defined as the left-right direction. In the example shown in FIG. 1, the open / close bodies 3 are provided in three upper and lower stages.

図９〜図１１を併せて参照し、各開閉体３は、筐体２内に出し入れされる収納部４を一体に備える。各開閉体３は、一体をなす収納部４とともに什器１Ａの引き出し５を構成する。各収納部４は、水平な底板４ａを有して上方に開放する直方体形状に設けられる。各収納部４は、底板４ａ、前後板４ｂ，４ｃ並びに左右側板４ｄを備える。前板４ｂは開閉体３で構成してもよい。開閉体３を引き出し５の表板、後板４ｃを引き出し５の奥板ということがある。開閉体３は、前面視で左右幅及び上下幅が収納部４よりも広い。以下、開閉体３における前面視で収納部４よりも外側に張り出す部分を外周部３ａという。 With reference to FIGS. 9 to 11 as well, each opening / closing body 3 is integrally provided with a storage portion 4 that is taken in and out of the housing 2. Each open / close body 3 constitutes a drawer 5 of the fixture 1A together with an integral storage portion 4. Each storage part 4 has a horizontal bottom plate 4a and is provided in a rectangular parallelepiped shape that opens upward. Each storage unit 4 includes a bottom plate 4a, front and rear plates 4b and 4c, and left and right side plates 4d. The front plate 4 b may be configured by the opening / closing body 3. The opening / closing body 3 may be referred to as the front plate of the drawer 5, and the rear plate 4 c may be referred to as the back plate of the drawer 5. The opening / closing body 3 has a left-right width and a vertical width wider than the storage portion 4 in front view. Hereinafter, the portion of the opening / closing body 3 that projects outward from the storage portion 4 in front view is referred to as an outer peripheral portion 3a.

筐体２は、上板（天井板）２ａ、後板２ｂ、左右側板２ｃ並びに下板２ｄを備える。上板２ａは、什器１Ａにおける水平な天面を形成する。後板２ｂは、什器１Ａにおける垂直な後面を形成する。左右側板２ｃは、什器１Ａにおける垂直な左右側面を形成する。
図１５を併せて参照し、左右側板２ｃの内側面には、上下方向に延びる前後の側部補強フレーム６ａ，６ｂが設けられる。前後の側部補強フレーム６ａ，６ｂの下端部間は、それぞれ下板２ｄ上面で左右方向に延びる前後の下部補強フレーム７ａ，７ｂにより連結される。前後の下部補強フレーム７ａ，７ｂは、下板２ｄとともに筐体２のベース部８を構成する。図示は略すが、前後の側部補強フレーム６ａ，６ｂの上端部間は、それぞれ上板２ａ下面で左右方向に延びる前後の上部補強フレームにより連結される。 The housing 2 includes an upper plate (ceiling plate) 2a, a rear plate 2b, left and right side plates 2c, and a lower plate 2d. The upper plate 2a forms a horizontal top surface of the fixture 1A. The rear plate 2b forms a vertical rear surface in the fixture 1A. The left right side plate 2c forms vertical left and right side surfaces in the fixture 1A.
Referring also to FIG. 15, front and rear side reinforcing frames 6a and 6b extending in the vertical direction are provided on the inner side surfaces of the left and right side plates 2c. The lower ends of the front and rear side reinforcing frames 6a and 6b are connected by front and rear lower reinforcing frames 7a and 7b extending in the left-right direction on the upper surface of the lower plate 2d. The front and rear lower reinforcing frames 7a and 7b constitute the base portion 8 of the housing 2 together with the lower plate 2d. Although not shown, the upper ends of the front and rear side reinforcing frames 6a and 6b are connected by front and rear upper reinforcing frames extending in the left-right direction on the lower surface of the upper plate 2a.

図１０、図１１を参照し、筐体２は、上下に並ぶ引き出し５の間を仕切る複数の仕切り板９を備える。これら複数の仕切り板９により、筐体２の内部空間は、複数の引き出し５の収納部４を個々に出し入れ可能な複数の引き出し収納空間５ｂに仕切られる。各引き出し収納空間５ｂにおいて、左右側板２ｃの内側面には、前後方向に延びるスライドレール１０が設けられる。スライドレール１０は、引き出し５の収納部４の左右側板４ｄに設けられるスライド部５ａを前後移動可能に支持する。各引き出し収納空間５ｂの前端開口の外周には、左右側板２ｃ及び上下板２ａ，２ｄ並びに各仕切り板９の前端縁部により枠状の框部１１が形成される。 Referring to FIGS. 10 and 11, the housing 2 includes a plurality of partition plates 9 that partition between the drawers 5 arranged vertically. By the plurality of partition plates 9, the internal space of the housing 2 is partitioned into a plurality of drawer storage spaces 5 b in which the storage portions 4 of the plurality of drawers 5 can be inserted and removed individually. In each drawer storage space 5b, a slide rail 10 extending in the front-rear direction is provided on the inner surface of the left and right side plates 2c. The slide rail 10 supports the slide part 5a provided on the left and right side plates 4d of the storage part 4 of the drawer 5 so as to be movable back and forth. On the outer periphery of the front end opening of each drawer storage space 5b, a frame-shaped flange 11 is formed by the left and right side plates 2c, the upper and lower plates 2a and 2d, and the front end edge of each partition plate 9.

各引き出し５の開閉体３は、収納部４を引き出し収納空間５ｂに納めた際に、引き出し収納空間５ｂの前端開口を閉じる。このとき、開閉体３の外周部３ａは、引き出し収納空間５ｂの框部１１に対向してほぼ当接する。全ての引き出し５の収納部４を筐体２内に納めると、複数の開閉体３により筐体２の前面開口が閉じられる。 The opening / closing body 3 of each drawer 5 closes the front end opening of the drawer storage space 5b when the storage portion 4 is stored in the drawer storage space 5b. At this time, the outer peripheral portion 3a of the opening / closing body 3 is substantially in contact with the flange portion 11 of the drawer storage space 5b. When the storage portions 4 of all the drawers 5 are stored in the housing 2, the front opening of the housing 2 is closed by the plurality of opening / closing bodies 3.

図１の例では、開閉体３の前面中央部に把手１２が設けられる。開閉体３の前面には、例えば把手１２の左右他側（図では左側）に施解錠装置１３が設けられる。一部の開閉体３の前面には、例えば把手１２の左右一側（図では右側）に太陽電池（ソーラーパネル、電源装置）１４が設けられる。
把手１２は、開閉体３の前面に形成された凹部内に移動可能に配置される。把手１２は、従来公知の構成、例えば特開２０１１−２４１５９９号公報に開示された「把手３」と同様の構成を備える。 In the example of FIG. 1, a handle 12 is provided in the center of the front surface of the opening / closing body 3. On the front surface of the opening / closing body 3, for example, a locking / unlocking device 13 is provided on the left and right other side (left side in the drawing) of the handle 12. A solar cell (solar panel, power supply device) 14 is provided on the front surface of a part of the opening / closing bodies 3, for example, on the left and right sides (right side in the figure) of the handle 12.
The handle 12 is movably disposed in a recess formed in the front surface of the opening / closing body 3. The handle 12 has a conventionally known configuration, for example, the same configuration as the “handle 3” disclosed in Japanese Patent Application Laid-Open No. 2011-241599.

図１３を併せて参照し、把手１２は、例えば引き出し５の左右両側に揺動可能に軸支されるラッチ板１２ａに不図示のロッド等の連結手段を介して連結される。ラッチ板１２ａは、慣用の付勢手段により遊端側が筐体２側に向けて付勢される。ラッチ板１２ａの遊端側は、筐体２側に固設される係止爪１２ｂに対して係合及び離脱可能とされる。ラッチ板１２ａは、把手１２の非操作時には、引き出し５の全閉時において遊端側を係止爪１２ｂに係合させ、引き出し５の引き出しをロックする。この状態から把手１２を操作すると、ラッチ板１２ａが揺動してその遊端側と係止爪１２ｂとの係合を解除させ、引き出し５を引き出し可能とする。すなわち、ラッチ板１２ａ及び係止爪１２ｂを含むラッチ部１２ｃは、引き出し５の閉時に係合状態となって引き出し５の意図せぬ引き出しを抑止する。 Referring also to FIG. 13, the handle 12 is connected to a latch plate 12 a that is pivotally supported on the left and right sides of the drawer 5 via a connecting means such as a rod (not shown). The latch plate 12a is urged toward the housing 2 on the free end side by conventional urging means. The free end side of the latch plate 12a can be engaged and disengaged with respect to a locking claw 12b fixed on the housing 2 side. When the handle 12 is not operated, the latch plate 12 a engages the free end side with the locking claw 12 b when the drawer 5 is fully closed, and locks the drawer 5. When the handle 12 is operated from this state, the latch plate 12a swings to release the engagement between the free end side and the locking claw 12b, and the drawer 5 can be pulled out. That is, the latch portion 12c including the latch plate 12a and the locking claw 12b enters an engaged state when the drawer 5 is closed, and prevents the drawer 5 from being unintentionally pulled out.

図１、図１４を参照し、施解錠装置１３は、電気機器としての電気式施解錠装置（電気錠）１３ａを備える。電気式施解錠装置１３ａは、例えばソレノイドユニット及び該ソレノイドユニットを作動させる制御基板（何れも不図示）等を備える。施解錠装置１３は、電気式施解錠装置１３ａを強制的に解錠可能な機械式施解錠装置（不図示）を備える。電気式施解錠装置１３ａ及び機械式施解錠装置は、従来公知の構成、例えば特開２０１１−２４１５９９号公報に開示された「電気式施解錠装置２６」、「機械式施解錠装置２５」と同様の構成を備える。 1 and 14, the locking / unlocking device 13 includes an electric locking / unlocking device (electric lock) 13a as an electric device. The electric locking / unlocking device 13a includes, for example, a solenoid unit and a control board (not shown) for operating the solenoid unit. The locking / unlocking device 13 includes a mechanical locking / unlocking device (not shown) that can forcibly unlock the electric locking / unlocking device 13a. The electric locking / unlocking device 13a and the mechanical locking / unlocking device are similar to the conventionally known configurations, for example, “electric locking / unlocking device 26” and “mechanical locking / unlocking device 25” disclosed in Japanese Patent Application Laid-Open No. 2011-241599. The configuration is provided.

前記制御基板は、什器１Ａに搭載された二次電池（電源）１５に電気的に接続される。電気式施解錠装置１３ａは、例えば什器１Ａから離れた場所にあるメインコントローラ（不図示）のカードリーダに認証カードを近づけると、この認証カードに対応する開閉体が解錠準備状態となり、その状態で当該対応する開閉体の解錠ボタンを押す等の操作を行うことで、前記ソレノイドユニットが作動し、電気式施解錠装置１３ａが解錠される。 The control board is electrically connected to a secondary battery (power source) 15 mounted on the fixture 1A. For example, when the electric locking / unlocking device 13a brings an authentication card close to a card reader of a main controller (not shown) located away from the fixture 1A, for example, the opening / closing body corresponding to the authentication card enters the unlocking preparation state. The solenoid unit is actuated by performing an operation such as pressing the unlocking button of the corresponding opening / closing body, and the electric locking / unlocking device 13a is unlocked.

太陽電池１４は、出力される電力によって二次電池１５を充電することができるように、二次電池１５と並列に電気的に接続される。これにより、定期的に二次電池１５の充電作業を実施することなく、常に二次電池１５を充電状態とし、その電力により電気錠の施解錠を行うことが可能となる。太陽電池１４と二次電池１５との間を電気的に接続する電路には、二次電池１５から太陽電池１４への電流の流れを阻止するダイオード１６のみが介在させている。一般的に、二次電池１５を保護する目的で組み込まれる定電圧回路及び過充電防止回路は、それ自体が電力を消費してしまうため、本実施形態では省略している。 The solar cell 14 is electrically connected in parallel with the secondary battery 15 so that the secondary battery 15 can be charged with the output electric power. Thus, the secondary battery 15 can be always charged and the electric lock can be locked and unlocked by the electric power without periodically performing the charging operation of the secondary battery 15. Only the diode 16 that blocks the flow of current from the secondary battery 15 to the solar cell 14 is interposed in the electric circuit that electrically connects the solar cell 14 and the secondary battery 15. In general, a constant voltage circuit and an overcharge prevention circuit incorporated for the purpose of protecting the secondary battery 15 consume power, and are omitted in this embodiment.

本実施形態で太陽電池１４を取り付ける什器は、オフィス等の室内に設置されるものであり、屋外に比べて照射される光量も制限されるため、太陽電池１４から出力される電力量も限られる。このため、電力の消費要素となるものを極力省くことで、二次電池１５を最大限充電可能とする。また、室内の照射光で期待できる太陽電池１４の発電量に対して、二次電池１５の容量は十分に大きく、二次電池１５の電圧に引き込まれるので、二次電池１５の電圧に収めるための定電圧回路を必要としない。また、トリクル充電以下の発電量であるため、過充電防止対策も必要としない。したがって、太陽電池１４と二次電池１５との問を電気的に接続する電路に、二次電池１５から太陽電池１４への電流の流れを阻止するダイオード１６のみを介在させた電気回路を適用可能である。 The fixture to which the solar cell 14 is attached in this embodiment is installed in a room such as an office, and the amount of light emitted from the solar cell 14 is also limited because the amount of light irradiated is limited compared to the outdoors. . For this reason, the secondary battery 15 can be charged to the maximum extent by eliminating power consumption elements as much as possible. Further, the capacity of the secondary battery 15 is sufficiently large with respect to the power generation amount of the solar battery 14 that can be expected from indoor irradiation light, and the voltage of the secondary battery 15 is drawn, so that the voltage of the secondary battery 15 can be kept. No constant voltage circuit is required. In addition, since the power generation is less than trickle charge, no overcharge prevention measures are required. Therefore, an electric circuit in which only the diode 16 that blocks the flow of current from the secondary battery 15 to the solar cell 14 is applied to the electric circuit that electrically connects the solar cell 14 and the secondary battery 15 can be applied. It is.

図１を参照し、太陽電池１４は、矩形の薄板状に形成されたモジュールであり、厚さ方向の一側面を受光面とする。太陽電池１４は、受光面を開閉体３の前面に沿わせ、図１の例では横長の姿勢（開閉体３と長手方向を一致させた姿勢）で配置され、開閉体３と一体的に開閉動する。太陽電池１４は、自然光（太陽光）及び屋内照明光を受けて起電し、生成した電力を二次電池１５に供給可能とする。太陽電池１４が開閉体３の前面に配置されることで、受光面に物品等が置かれて採光量を低下させる虞が無く、かつ受光面が開閉体３の前面に配置されることから、壁又は他の什器等の隣接により採光量を低下させる虞も無い。 Referring to FIG. 1, a solar cell 14 is a module formed in a rectangular thin plate shape, and one side surface in the thickness direction is a light receiving surface. The solar cell 14 has a light receiving surface along the front surface of the opening / closing body 3 and is disposed in a horizontally long posture (an attitude in which the longitudinal direction coincides with the opening / closing body 3) in the example of FIG. Move. The solar cell 14 generates electricity upon receiving natural light (sunlight) and indoor illumination light, and enables the generated power to be supplied to the secondary battery 15. Since the solar cell 14 is disposed on the front surface of the opening / closing body 3, there is no possibility that articles or the like are placed on the light receiving surface and the amount of light collected is reduced, and the light receiving surface is disposed on the front surface of the opening / closing body 3. There is no risk of reducing the amount of light collected due to adjacent walls or other fixtures.

太陽電池１４は、照度の明暗及びムラ等に起因して起電力が変動し易いので、電気式施解錠装置１３ａと直には電気的に接続されず、二次電池１５を介して電気式施解錠装置１３ａに電気的に接続される。二次電池１５は、電気式施解錠装置１３ａに電力を供給して駆動させる。二次電池１５は、太陽電池１４の発電により再充電可能とされる。 Since the electromotive force of the solar cell 14 is likely to fluctuate due to the brightness and darkness and unevenness of the illuminance, the solar cell 14 is not directly electrically connected to the electric locking / unlocking device 13a and is electrically connected via the secondary battery 15. It is electrically connected to the locking device 13a. The secondary battery 15 supplies electric power to the electric locking / unlocking device 13a to drive it. The secondary battery 15 can be recharged by the power generation of the solar battery 14.

太陽電池１４は、複数段の引き出し５の内、一部の引き出し５の開閉体３に取り付けられる。具体的に、太陽電池１４は、最上段の引き出し５を含み、最下段の引き出し５を避けた引き出し５の開閉体３に取り付けられる。図１に示す例では、太陽電池１４は、最下段の引き出し５のみを避けて上二段の引き出し５の開閉体３に取り付けられる。太陽電池１４は、什器１Ａにおける極力光の当たり易い位置に集約して配置されることで、設置数及びサイズの増加が抑えられる。太陽電池１４は、少なくとも引き出し５及び電気式施解錠装置１３ａの数よりも少ない数に設けられる。 The solar cell 14 is attached to the opening / closing body 3 of some of the drawers 5 of the plurality of drawers 5. Specifically, the solar cell 14 includes the uppermost drawer 5 and is attached to the opening / closing body 3 of the drawer 5 that avoids the lowermost drawer 5. In the example shown in FIG. 1, the solar cell 14 is attached to the opening / closing body 3 of the upper two drawers 5 avoiding only the lowermost drawer 5. The solar cells 14 are arranged in a concentrated manner at a position where the light can be as much as possible in the fixture 1A, so that an increase in the number and size of installation can be suppressed. The solar cells 14 are provided in a number smaller than at least the number of the drawers 5 and the electric locking / unlocking devices 13a.

図１に示す什器１Ａでは、電気式施解錠装置１３ａ及び二次電池１５は、全引き出し５の開閉体３に取り付けられる。各引き出し５において、二次電池１５と電気式施解錠装置１３ａとは、配線１７を介して電気的に接続される。上二段の引き出し５の太陽電池１４は、それぞれ上二段の引き出し５の二次電池１５と配線１８を介して電気的に接続される。両太陽電池１４は、配線１９ａ等を介して互いに電気的に接続されるとともに、配線１９ｂ等を介して最下段の引き出し５の二次電池１５に電気的に接続される。配線１９ａ，１９ｂは、少なくとも一部が筐体２に配置されてもよい。 In the fixture 1 </ b> A shown in FIG. 1, the electric locking / unlocking device 13 a and the secondary battery 15 are attached to the opening / closing body 3 of the full drawer 5. In each drawer 5, the secondary battery 15 and the electric locking / unlocking device 13 a are electrically connected via the wiring 17. The solar cells 14 in the upper two-stage drawers 5 are electrically connected to the secondary batteries 15 in the upper two-stage drawers 5 via wirings 18 respectively. Both the solar cells 14 are electrically connected to each other via the wiring 19a and the like, and are also electrically connected to the secondary battery 15 of the lowermost drawer 5 via the wiring 19b and the like. At least a part of the wirings 19 a and 19 b may be arranged in the housing 2.

図２に示す什器１Ｂでは、太陽電池１４は、最上段の引き出し５の開閉体３のみに取り付けられ、電気式施解錠装置１３ａは、全引き出し５の開閉体３に取り付けられ、二次電池１５は、各引き出し５とは分離して筐体２の例えば上板２ａに取り付けられる。太陽電池１４は、配線２１等を介して二次電池１５に電気的に接続される。二次電池１５は、配線２２等を介して各引き出し５の電気式施解錠装置１３ａに電気的に接続される。配線２２は、少なくとも一部が筐体２に配置されてもよい。 In the fixture 1B shown in FIG. 2, the solar cell 14 is attached only to the opening / closing body 3 of the uppermost drawer 5, and the electric locking / unlocking device 13 a is attached to the opening / closing body 3 of all the drawers 5. Is attached to, for example, the upper plate 2 a of the housing 2 separately from each drawer 5. The solar cell 14 is electrically connected to the secondary battery 15 via the wiring 21 or the like. The secondary battery 15 is electrically connected to the electric locking / unlocking device 13a of each drawer 5 via the wiring 22 or the like. At least a part of the wiring 22 may be arranged in the housing 2.

図２に示す什器１Ｂでは、二次電池１５は、筐体２の上板２ａに沿うように配置される。二次電池１５は、上板２ａの他、左右側板２ｃ、後板２ｂ及び下板２ｄの何れかの板部に沿うように配置されてもよい。これにより、筐体２の内部空間（収納空間）への二次電池１５の張り出しが抑えられ、什器１Ａの収納容量が確保される。複数の開閉体３に二次電池１５が配置される場合と比べて、二次電池１５の数が減ることによりコスト増が抑えられるとともに、太陽電池１４の配置自由度が向上してより効率よく発電可能となる。二次電池１５は、筐体２の上板２ａ、左右側板２ｃ、後板２ｂ及び下板２ｄの内、複数の板部に配置してもよい。 In the fixture 1 </ b> B shown in FIG. 2, the secondary battery 15 is arranged along the upper plate 2 a of the housing 2. The secondary battery 15 may be arranged along any one of the left and right side plates 2c, the rear plate 2b, and the lower plate 2d in addition to the upper plate 2a. Thereby, the extension of the secondary battery 15 to the internal space (storage space) of the housing 2 is suppressed, and the storage capacity of the fixture 1A is secured. Compared with the case where the secondary batteries 15 are arranged in the plurality of opening / closing bodies 3, the number of secondary batteries 15 is reduced, thereby suppressing an increase in cost and improving the degree of freedom of arrangement of the solar cells 14 and more efficiently. Power generation is possible. The secondary battery 15 may be disposed on a plurality of plate portions among the upper plate 2a, the left and right side plates 2c, the rear plate 2b, and the lower plate 2d of the housing 2.

図３、図４に示す例は、複数のヒンジ開閉式の扉（開閉体３３）を備える什器である。
図３に示す什器１Ｃでは、左右に並ぶ一対のヒンジ開閉式の開閉体３３が上下三段に並んで設けられ、最上段の一対の開閉体３３にそれぞれ太陽電池１４が取り付けられ、電気式施解錠装置１３ａは全開閉体３３に取り付けられ、二次電池１５は各引き出し５とは分離して筐体２の例えば上板２ａに取り付けられる。両太陽電池１４は、配線２３等を介して互いに電気的に接続されるとともに二次電池１５に電気的に接続される。二次電池１５は、配線２４等を介して各開閉体３３の電気式施解錠装置１３ａに電気的に接続される。配線２３，２４は、少なくとも一部が筐体２に配置されてもよい。 The example shown in FIGS. 3 and 4 is a fixture including a plurality of hinged doors (opening / closing body 33).
In the fixture 1C shown in FIG. 3, a pair of hinged opening / closing bodies 33 arranged side by side are provided in three upper and lower stages, and solar cells 14 are attached to the uppermost pair of opening / closing bodies 33, respectively. The lock device 13 a is attached to all the opening / closing bodies 33, and the secondary battery 15 is attached to, for example, the upper plate 2 a of the housing 2 separately from each drawer 5. Both solar cells 14 are electrically connected to the secondary battery 15 while being electrically connected to each other via the wiring 23 and the like. The secondary battery 15 is electrically connected to the electrical locking / unlocking device 13a of each opening / closing body 33 via the wiring 24 or the like. The wirings 23 and 24 may be at least partially arranged in the housing 2.

図４に示す什器１Ｄは、図３の例に対し、太陽電池１４が最上段の一対の開閉体３３の一方のみに取り付けられる点で異なる。
図３、図４に示す例では、各段の一対の開閉体３３が図中右側のヒンジ３０を介して同一方向に開閉する。太陽電池１４は、開閉体３３のヒンジ３０側で縦長に配置され、開閉体３３の開閉が重くなり難くする。各段の一対の開閉体３３は、所謂観音開きに開閉する構成でもよい。 The fixture 1D shown in FIG. 4 differs from the example of FIG. 3 in that the solar cell 14 is attached to only one of the pair of uppermost opening / closing bodies 33.
In the example shown in FIGS. 3 and 4, the pair of opening / closing bodies 33 at each stage opens and closes in the same direction via the hinge 30 on the right side in the drawing. The solar cell 14 is disposed vertically on the hinge 30 side of the opening / closing body 33, and the opening / closing of the opening / closing body 33 is difficult to be heavy. The pair of opening / closing bodies 33 at each stage may be configured to open and close in a so-called double door.

複数の開閉体３，３３の全てに太陽電池１４及び二次電池１５を設けると、特に開閉体３，３３の数が多い場合には大きなコストアップとなる。太陽電池１４を少なくとも電気機器を備える開閉体３，３３の数よりも少ない数に設け、効率よく発電できる位置（上段側）に限定、集約して太陽電池１４を配置するとともに、二次電池１５を少なくとも前記開閉体３，３３の数よりも少ない数に設けることで、開閉体３，３３を多数設ける場合にもコストアップが抑えられる。 If the solar battery 14 and the secondary battery 15 are provided in all of the plurality of opening / closing bodies 3, 33, particularly when the number of the opening / closing bodies 3, 33 is large, the cost is greatly increased. The solar cells 14 are provided in a number smaller than the number of the open / close bodies 3 and 33 including at least electrical devices, and are limited to the position (upper side) where power can be generated efficiently, and the solar cells 14 are arranged in a concentrated manner, and the secondary battery 15 By providing at least a number smaller than the number of the opening / closing bodies 3, 33, the cost increase can be suppressed even when a large number of opening / closing bodies 3, 33 are provided.

例えば、太陽電池１４又は二次電池１５を何れかの開閉体に集約して配置した場合、該開閉体が閉じたときにのみ他の開閉体の電気式施解錠装置１３ａへの電力供給を可能とすると、該開閉体の開閉状況によって他の開閉体の電気式施解錠装置１３ａを駆動できなくなる。このため、開閉体を開いた状態でも他の開閉体に電力供給できるように、例えば引き出し式の開閉体３であれば、金属製のスライドレール１０等の連結部を含んで、開閉体に配置した二次電池１５と他の開閉体の電気式施解錠装置１３ａとの間の電路を形成してもよい。また、例えばヒンジ開閉式の開閉体３３であれば、金属製のヒンジ３０等の連結部を含んで前記電路を形成してもよい。前記連結部は、開閉体３，３３を筐体２に開閉動可能に連結する機能を有するものであり、単なる着脱自在な通電コネクタとは異なる。スライドレール１０及びヒンジ３０等の開閉部品を用いて電路を形成することで、弛み又は伸縮代を有する配線を用いる場合と比べて、配線と開閉体との干渉等が無くなる。スライドレール１０及びヒンジ３０等の開閉部品とは別に、開閉体の開閉に応じて接点を摺動させる可動接点を含む電路を形成してもよい。また、適宜の配線を用いて電路を形成することも可能である。 For example, when the solar cell 14 or the secondary battery 15 is arranged in one of the opening / closing bodies, power can be supplied to the electric lock / unlock device 13a of the other opening / closing body only when the opening / closing body is closed. Then, the electric locking / unlocking device 13a of another opening / closing body cannot be driven depending on the opening / closing state of the opening / closing body. For this reason, in order to supply power to other opening / closing bodies even when the opening / closing body is opened, for example, in the case of the pull-out opening / closing body 3, it is arranged on the opening / closing body including a connecting portion such as a metal slide rail 10 or the like. You may form the electrical circuit between the secondary battery 15 and the electric locking / unlocking device 13a of another opening / closing body. Further, for example, in the case of a hinge opening / closing type opening / closing body 33, the electric circuit may be formed including a connecting portion such as a metal hinge 30. The connecting portion has a function of connecting the opening and closing bodies 3 and 33 to the housing 2 so as to be openable and closable, and is different from a simple detachable energizing connector. By forming the electric circuit using opening / closing components such as the slide rail 10 and the hinge 30, interference between the wiring and the opening / closing body is eliminated as compared with the case of using the wiring having a slack or expansion / contraction allowance. In addition to the opening / closing components such as the slide rail 10 and the hinge 30, an electric circuit including a movable contact that slides the contact in accordance with opening / closing of the opening / closing body may be formed. It is also possible to form the electric circuit using appropriate wiring.

開閉体３，３３を開く際、引き出し式の開閉体３の場合には、前面側に使用者が立っていたり、ヒンジ開閉式の開閉体３３の場合には、前面が筐体２側を向いてしまったりする。このため、例え太陽電池１４を光の当たり易い開閉体３，３３に取り付けたとしても、開閉体３，３３を開く際には、その前面に取り付けた太陽電池１４への光の当たりが阻害され、太陽電池１４の発電量が低下する。また、開閉体３，３３を開いている時間は、開閉体３，３３を閉じている時間よりも短い。このような理由から、前述のような電路の工夫を行うことなく、開閉体３，３３を閉じたときのみ太陽電池１４を充電可能とする構成としても、開閉体３，３３の開時にはそもそも発電量が少ないことから、可動接点等を無くすことによるコストメリットの方が大きいと考えられる。 When opening the opening / closing bodies 3, 33, a user stands on the front side in the case of the pull-out type opening / closing body 3, or in the case of the hinge opening / closing type opening / closing body 33, the front side faces the housing 2 side. I will. For this reason, even if the solar cell 14 is attached to the openable and closable bodies 3 and 33 that are easily exposed to light, when the openable and closable bodies 3 and 33 are opened, the light hitting the solar cell 14 attached to the front surface is obstructed. The power generation amount of the solar cell 14 is reduced. Further, the time for opening the opening / closing bodies 3, 33 is shorter than the time for closing the opening / closing bodies 3, 33. For this reason, the solar cell 14 can be charged only when the opening and closing bodies 3 and 33 are closed without devising the electric circuit as described above. Since the amount is small, it is considered that the cost merit by eliminating the movable contact is larger.

図５に示す什器１Ｅは、複数のヒンジ開閉式の開閉体３３が上下に並ばず左右に並ぶ構成で、開閉体３３の上下中間部を境に、開閉体３３の下半部を避けて上半部に太陽電池１４を取り付ける。この構成でも、上段側の開閉体３に太陽電池１４を取り付ける場合と同様、太陽電池１４が什器１Ｅにおける極力光の当たり易い位置に集約して配置され、設置数及びサイズの増加が抑えられる。この構成は、単一の開閉体のみを備える什器にも適用できる。なお、単一の開閉体はヒンジ開閉式か引き出し式かは問わない。 The fixture 1E shown in FIG. 5 has a configuration in which a plurality of hinge opening / closing type opening / closing bodies 33 are arranged side by side rather than vertically, and the upper half of the opening / closing body 33 is separated from the lower half of the opening / closing body 33. A solar cell 14 is attached to the half. Even in this configuration, as in the case where the solar cell 14 is attached to the upper-side opening / closing body 3, the solar cells 14 are collectively arranged at a position where the light is as much as possible in the fixture 1E, and the increase in the number and size of installation is suppressed. This configuration can also be applied to a fixture having only a single opening / closing body. The single opening / closing body may be a hinge opening / closing type or a drawer type.

図５に示す什器１Ｅでは、三つの筐体２が左右に並んで設けられ、各筐体２の前面開口がそれぞれ観音開きの一対の開閉体３３により開閉される。換言すれば、各筐体２と一対の開閉体３３とを組み付けた組付体２Ｅが左右に三つ並んで設けられる。

In other words, three assembling bodies 2E in which each housing 2 and a pair of opening / closing bodies 33 are assembled are provided side by side.
The secondary battery 15 and the electric locking / unlocking device 13a are attached to the opening / closing body 33R on the right side of the figure among the pair of opening / closing bodies 33 that open and close each housing 2. The left opening / closing body 33L in the drawing is locked / unlocked along with the locking / unlocking of the right opening / closing body 33R. The solar cell 14 is attached only to one opening / closing body 33. The solar battery 14 is electrically connected to the secondary battery 15 of the opening / closing body 33 to which the solar battery 14 is attached via the wiring 25 and is electrically connected to the secondary battery 15 of the other opening / closing body 33 via the wiring 26 and the like.

The wirings 26 and 29 electrically connect at least one of the solar battery 14, the secondary battery 15, and the electric locking / unlocking device 13a between the three housings 2 (between the assembled bodies 2E). I just need it.

図５、図６に示す例では、太陽電池１４は、開閉体３３のヒンジ３０側で縦長に配置される。なお、図５、図６に示す例に対し、各筐体２の開口が観音開きの一対の開閉体３３で開閉される構成に限らず、各筐体２の開口が単一のヒンジ開閉式の開閉体３３で同一方向に開閉される構成（図３、図４参照）であってもよい。
図７に示す什器１Ｇでは、複数の引き出し式の開閉体３が上下に並ぶ領域と複数のヒンジ開閉式の開閉体３３が左右に並ぶ領域とが混在し、それぞれの領域で前述の太陽電池１４等の配置が適用される。 In the example shown in FIGS. 5 and 6, the solar cell 14 is arranged vertically on the hinge 30 side of the opening / closing body 33. 5 and 6, the opening of each housing 2 is not limited to a configuration in which the opening of each housing 2 is opened and closed by a pair of double doors 33, but the opening of each housing 2 is a single hinge opening / closing type. The structure (refer FIG. 3, FIG. 4) opened and closed by the opening-closing body 33 in the same direction may be sufficient.
