A solar cell is usually combined with a rechargeable power storage such as a secondary battery or an electric double layer capacitor to constitute a power supply device of an electric device.
By the way, in recent years, the power generation efficiency has been improved, and a solar cell capable of generating power even under low illuminance has been developed, so that the power storage unit can be charged even with low illuminance indoor lights such as ceiling lighting. . In addition, the power consumption of the electric lock is also decreasing, and there is an increasing demand for furniture that can drive the electric lock with electric power generated by a solar cell.
Furniture separated from an external power supply by providing a power storage unit has the advantage of lowering costs and eliminating the burden of wiring processing, as compared to a furniture using an external power supply, since wiring is not routed. Charging of the power storage unit can be performed by power generation of a solar cell.
However, when a power storage unit that can be charged by a solar cell is attached to all of the switches together with the electric equipment, the number of power storage units increases, the cost increases, and the power storage unit reduces the storage capacity of furniture.

  The present invention has been made in view of the above-described problem, and has an object to suppress the influence on the cost and storage capacity of a power storage unit that can be charged by a solar cell in a fixture including the solar cell.

In order to achieve the above object, the present invention employs the following means.
That is, the furniture according to the present invention includes a housing that forms a storage space, an opening / closing body that allows articles to be taken in and out of the housing, an electric device provided in the opening / closing body, and power supplied to the electric device. A power supply device that can be supplied, the power supply device includes a solar cell, and a power storage unit that can be charged by the solar cell and can supply power to the electric device. The power storage unit is attached to the body, and the power storage unit is attached to the housing.
According to this configuration, it becomes easier to supply power to a plurality of electric devices from the power storage unit, and the number of power storage units can be easily reduced as compared to a case where the power storage unit is attached to all the switches together with the electric devices.
In addition, by installing the power storage unit in a relatively large housing, it is easier to secure the mounting space for the power storage unit, and to suppress the protrusion of the power storage unit into the storage space as compared with the case where the power storage unit is mounted on the opening and closing body. Can be.
In addition, by attaching the power storage unit to the housing, the structure of the opening / closing body is simplified, the degree of freedom of design of the opening / closing body is improved, and the weight and bulk of the opening / closing body are reduced, and the workability of assembling and installing furniture is reduced. And the opening and closing of the opening and closing body can be made lighter.

Further, in the above-mentioned furniture, the connector further comprises a connector portion between the opening and closing body and the housing, which can electrically connect the solar cell attached to the opening and closing body and the power storage body attached to the housing. The part may be configured to be electrically connected when the opening / closing body is closed and to be disconnected when the opening / closing body is opened.
According to this configuration, the power storage device attached to the housing can be charged by the solar cell attached to the opening / closing member only by assembling the opening / closing member to the housing to close the housing. In addition, the connector can be used as a limit switch for detecting the opening / closing operation of the opening / closing body, and the cost can be reduced by eliminating the need for a dedicated limit switch.

In the above-mentioned furniture, a drawer including the opening / closing body may be provided, and the connector portion may be provided in a latch portion that is engaged when the drawer is closed.
In the above-mentioned furniture, a drawer including the opening / closing body may be provided, and the connector may be provided on the outer peripheral back surface of the opening / closing body which is a front plate of the drawer.
In the above-mentioned furniture, a drawer including the opening / closing body may be provided, and the connector portion may be provided on a back surface of a back plate located on a back side in a drawing direction of the drawer.
According to this configuration, the exposure of the connector portion can be suppressed, and the appearance can be improved and contact can be prevented.

Further, in the furniture described above, a connection portion is provided between the opening and closing body and the housing so as to openably and closably connect the opening and closing body to the housing, and the sun attached to the opening and closing body via the connection portion. A configuration in which a battery and the power storage unit attached to the housing are electrically connected may be employed.
According to this configuration, the power storage unit attached to the housing can be charged by the solar cell attached to the opening / closing unit only by assembling the opening / closing unit to the housing.

The furniture 1A includes a rectangular parallelepiped housing 2 placed on the floor, and a plurality of opening / closing members 3 for opening and closing the front opening of the housing 2. Each opening / closing body 3 has a plate shape along a vertical front surface of the furniture 1A, and is formed in a rectangular shape long in the horizontal direction when viewed from the front. Hereinafter, the horizontal direction when viewed from the front is referred to as the left-right direction. In the example shown in FIG. 1, each of the opening / closing bodies 3 is provided in three rows vertically.

  With reference to FIGS. 9 to 11, each opening / closing body 3 is integrally provided with a storage section 4 that is inserted into and removed from the housing 2. Each opening / closing body 3 constitutes a drawer 5 of the furniture 1A together with the storage section 4 forming an integral part. Each storage section 4 is provided in a rectangular parallelepiped shape having a horizontal bottom plate 4a and opening upward. Each storage section 4 includes a bottom plate 4a, front and rear plates 4b and 4c, and left and right side plates 4d. The front plate 4b may be constituted by the opening / closing body 3. The opening / closing body 3 may be referred to as a front plate of the drawer 5, and the rear plate 4c may be referred to as a back plate of the drawer 5. The opening / closing body 3 has a wider left / right and upper / lower width than the storage section 4 when viewed from the front. Hereinafter, a portion of the opening / closing body 3 that protrudes outward from the storage portion 4 when viewed from the front is referred to as an outer peripheral portion 3a.

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 furniture 1A. The rear plate 2b forms a vertical rear surface of the furniture 1A. The left and right plates 2c form vertical left and right side surfaces of the furniture 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 end portions 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 reinforcement frames 7a and 7b together with the lower plate 2d constitute a base portion 8 of the housing 2. Although not shown, the upper end portions 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.

  Referring to FIGS. 10 and 11, the housing 2 includes a plurality of partition plates 9 that partition between 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 5b in which the storage portions 4 of the plurality of drawers 5 can be individually taken in and out. In each drawer storage space 5b, a slide rail 10 extending in the front-rear direction is provided on the inner side surface of the left and right side plate 2c. The slide rail 10 supports a slide part 5 a provided on the left and right side plates 4 d 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 frame portion 11 is formed by the left and right side plates 2c, the upper and lower plates 2a, 2d, and the front end edge of each partition plate 9.

  The opening / closing body 3 of each drawer 5 closes the front end opening of the drawer storage space 5b when the storage unit 4 is placed 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 frame 11 of the drawer storage space 5b. When the storage units 4 of all the drawers 5 are placed in the housing 2, the front opening of the housing 2 is closed by the plurality of opening / closing bodies 3.

In the example of FIG. 1, a handle 12 is provided at 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 other side (left side in the figure) of the handle 12. For example, a solar cell (solar panel, power supply) 14 is provided on the front surface of a part of the opening / closing body 3 on one side (right side in the figure) of the handle 12, for example.
The handle 12 is movably disposed in a recess formed on 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.

  Referring also to FIG. 13, the handle 12 is connected to a latch plate 12 a pivotally supported on the left and right sides of the drawer 5 via a connecting means such as a rod (not shown). The free end side of the latch plate 12a is urged toward the housing 2 by conventional urging means. The free end side of the latch plate 12a can be engaged with and disengaged from a locking claw 12b fixed to the housing 2 side. When the handle 12 is not operated, the latch plate 12a locks the drawer 5 by engaging its free end with the locking claw 12b when the drawer 5 is fully closed. 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 is brought into an engaged state when the drawer 5 is closed, thereby suppressing unintended withdrawal of the drawer 5.

  1 and 14, the locking and unlocking device 13 includes an electric locking and 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 and unlocking device 13 includes a mechanical locking and unlocking device (not shown) that can forcibly unlock the electric locking and unlocking device 13a. The electric locking / unlocking device 13a and the mechanical locking / unlocking device are the same as those of a conventionally known configuration, for example, “Electrical locking / unlocking device 26” and “Mechanical locking / unlocking device 25” disclosed in JP-A-2011-241599. Is provided.

  The control board is electrically connected to a secondary battery (power supply) 15 mounted on the furniture 1A. When the authentication card is brought close to a card reader of a main controller (not shown) located away from the furniture 1A, for example, the electric locking and unlocking device 13a puts the opening / closing body corresponding to the authentication card into an unlocking ready state, By performing an operation such as pressing an unlock button of the corresponding opening / closing body, the solenoid unit is operated, and the electric locking / unlocking device 13a is unlocked.

  The solar cell 14 is electrically connected in parallel with the secondary battery 15 so that the secondary battery 15 can be charged by the output power. Accordingly, the secondary battery 15 can always be 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 a diode 16 for preventing a current from flowing from the secondary battery 15 to the solar cell 14 is interposed in an electric path for electrically connecting the solar battery 14 and the secondary battery 15. Generally, a constant voltage circuit and an overcharge prevention circuit that are incorporated for the purpose of protecting the secondary battery 15 consume power in themselves, and thus are omitted in the present embodiment.

  Furniture to which the solar cell 14 is attached in the present embodiment is installed indoors such as an office, and the amount of light emitted is limited as compared with the outdoors, so the amount of power output from the solar cell 14 is also limited. . Therefore, the secondary battery 15 can be charged as much as possible by minimizing power consumption elements. In addition, the capacity of the secondary battery 15 is sufficiently large with respect to the amount of power generated by the solar cell 14 which can be expected by the irradiation light in the room, and the capacity of the secondary battery 15 is drawn to the voltage of the secondary battery 15. Does not require a constant voltage circuit. Further, since the amount of power generation is equal to or less than trickle charge, no overcharge prevention measure is required. Therefore, it is possible to apply an electric circuit in which only the diode 16 for preventing the flow of current from the secondary battery 15 to the solar cell 14 is interposed in the electric circuit for electrically connecting the solar cell 14 and the secondary battery 15. It is.

  Referring to FIG. 1, 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 arranged in a horizontally long posture (a posture in which the longitudinal direction coincides with the opening / closing body 3) in the example of FIG. Move. The solar cell 14 generates electricity by 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 an article or the like is placed on the light receiving surface to reduce the amount of collected light, and the light receiving surface is disposed on the front surface of the opening / closing body 3. There is no danger of lowering the amount of collected light due to the proximity of a wall or other furniture.

  The solar cell 14 is not directly electrically connected to the electric locking / unlocking device 13a because the electromotive force is likely to fluctuate due to brightness and unevenness and unevenness of the illuminance. It is electrically connected to the lock device 13a. The secondary battery 15 is driven by supplying electric power to the electric locking and unlocking device 13a. The secondary battery 15 can be recharged by the power generation of the solar cell 14.

  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 is attached to the opening / closing body 3 of the drawer 5 including the uppermost drawer 5 and avoiding 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-stage drawer 5 while avoiding only the lowermost drawer 5. Since the solar cells 14 are collectively arranged at a position where light can easily hit the furniture 1A, increase in the number of installations and size can be suppressed. The number of the solar cells 14 is provided at least smaller than the number of the drawers 5 and the electric locking / unlocking devices 13a.

  In the furniture 1A shown in FIG. 1, the electric locking / unlocking device 13a and the secondary battery 15 are attached to the opening and closing body 3 of the all drawers 5. In each drawer 5, the secondary battery 15 and the electric locking / unlocking device 13a are electrically connected via the wiring 17. The solar cells 14 in the upper two-stage drawer 5 are electrically connected to the secondary batteries 15 in the upper two-stage drawer 5 via wiring 18. The two solar cells 14 are electrically connected to each other via a wiring 19a and the like, and are also electrically connected to the secondary battery 15 of the lowermost drawer 5 via a wiring 19b and the like. At least a part of the wires 19a and 19b may be arranged in the housing 2.

  In the furniture 1B shown in FIG. 2, the solar cell 14 is attached only to the opening / closing body 3 of the uppermost drawer 5, the electric locking / unlocking device 13a is attached to the opening / closing body 3 of all the drawers 5, and the secondary battery 15 Is attached to, for example, the upper plate 2 a of the housing 2 separately from the drawers 5. The solar cell 14 is electrically connected to the secondary battery 15 via the wiring 21 and the like. The secondary battery 15 is electrically connected to the electric locking / unlocking device 13a of each drawer 5 via the wiring 22 and the like. At least a part of the wiring 22 may be arranged in the housing 2.

  In the furniture 1B shown in FIG. 2, the secondary battery 15 is arranged along the upper plate 2a 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 protrusion of the secondary battery 15 into the internal space (storage space) of the housing 2 is suppressed, and the storage capacity of the furniture 1A is secured. Compared to the case where the secondary batteries 15 are arranged on the plurality of opening / closing bodies 3, the number of the secondary batteries 15 is reduced, thereby suppressing an increase in cost. Power generation becomes possible. The secondary battery 15 may be disposed on a plurality of plate portions of the upper plate 2a, the left and right side plates 2c, the rear plate 2b, and the lower plate 2d of the housing 2.

The example shown in FIGS. 3 and 4 is a furniture provided with a plurality of hinged doors (opening / closing body 33).
In the furniture 1C shown in FIG. 3, a pair of hinged openable / closable bodies 33 arranged on the left and right are provided in three upper and lower stages, and the solar cell 14 is attached to each of the uppermost pair of openable / closable bodies 33. The lock device 13a is attached to the entire opening / closing body 33, and the secondary battery 15 is attached to, for example, the upper plate 2a of the housing 2 separately from each drawer 5. The two solar cells 14 are electrically connected to each other via a wiring 23 and the like, and are also electrically connected to the secondary battery 15. The secondary battery 15 is electrically connected to the electric locking / unlocking device 13a of each opening / closing body 33 via the wiring 24 or the like. At least a part of the wirings 23 and 24 may be arranged in the housing 2.

The furniture 1D shown in FIG. 4 is different from the example of FIG. 3 in that the solar cell 14 is attached to only one of the pair of opening / closing bodies 33 at the top.
In the example shown in FIGS. 3 and 4, the pair of opening / closing bodies 33 of each stage opens and closes in the same direction via the hinge 30 on the right side in the figure. The solar cell 14 is vertically arranged on the hinge 30 side of the opening / closing body 33, so that the opening / closing of the opening / closing body 33 does not become heavy. The pair of opening / closing bodies 33 of each stage may be configured to open and close in a so-called double door opening.

  If the solar battery 14 and the secondary battery 15 are provided in all of the plurality of opening / closing members 3 and 33, the cost increases significantly especially when the number of the opening and closing members 3 and 33 is large. The solar cells 14 are provided at least in a number smaller than the number of the opening / closing members 3 and 33 provided with the electric devices, and are limited to a position (upper side) where power can be efficiently generated. Is provided in at least a number smaller than the number of the opening / closing members 3 and 33, so that cost increase can be suppressed even when a large number of the opening / closing members 3 and 33 are provided.

  For example, when the solar cell 14 or the secondary battery 15 is arranged in one of the opening and closing members, power can be supplied to the electric locking / unlocking device 13a of the other opening and closing member only when the closing member 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, for example, in the case of the pull-out type opening / closing body 3, it is arranged on the opening / closing body including a connecting portion such as a metal slide rail 10 so that power can be supplied to other opening / closing bodies even when the opening / closing body is opened. An electric path between the rechargeable battery 15 and the electric locking / unlocking device 13a of another opening / closing body may be formed. Further, for example, in the case of a hinge-openable opening / closing body 33, the electric path may be formed including a connecting portion such as a metal hinge 30 or the like. The connecting portion has a function of connecting the opening and closing members 3 and 33 to the housing 2 so as to be capable of opening and closing, and is different from a simple detachable energizing connector. By forming the electric path using the opening / closing parts 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 where a wiring having a slack or an expansion / contraction margin is used. In addition to the open / close parts such as the slide rail 10 and the hinge 30, an electric path including a movable contact that slides the contact according to the opening / closing of the open / close body may be formed. Further, it is also possible to form an electric path using appropriate wiring.

  When the opening / closing members 3 and 33 are opened, in the case of the drawer-type opening / closing member 3, a user stands on the front side, and in the case of the hinge opening / closing type opening / closing member 33, the front surface faces the housing 2 side. Or For this reason, even if the solar cell 14 is attached to the opening / closing members 3 and 33 which are easily exposed to light, when opening the opening / closing members 3 and 33, light hitting the solar cell 14 attached to the front surface thereof is hindered. As a result, the amount of power generated by the solar cell 14 decreases. The time during which the opening and closing members 3 and 33 are open is shorter than the time when the opening and closing members 3 and 33 are closed. For this reason, even if the solar cell 14 can be charged only when the switches 3 and 33 are closed without devising the electric circuit as described above, when the switches 3 and 33 are opened, power is generated in the first place. Since the amount is small, it is considered that the cost merit by eliminating the movable contact and the like is greater.

  The furniture 1E shown in FIG. 5 has a configuration in which a plurality of hinged openable and closable opening and closing bodies 33 are not arranged vertically but arranged side by side. Attach the solar cell 14 to the half. Also in this configuration, as in the case where the solar cell 14 is attached to the upper opening / closing body 3, the solar cells 14 are collectively arranged at a position where the light easily hits the furniture 1 </ b> E as much as possible, and the number of installations and the increase in size are suppressed. This configuration can also be applied to furniture having only a single opening / closing body. It should be noted that the single opening / closing body does not matter whether it is a hinge opening / closing type or a drawer type.

In the furniture 1E shown in FIG. 5, three housings 2 are provided side by side, and the front opening of each housing 2 is opened and closed by a pair of open / close bodies 33 each of which is a double door. In other words, three assembled bodies 2E in which each housing 2 and a pair of opening and closing bodies 33 are assembled are provided side by side on the left and right.
The secondary battery 15 and the electric locking / unlocking device 13a are attached to the opening / closing body 33R on the right side in the drawing, of the pair of opening / closing bodies 33 that open and close each housing 2. The opening / closing body 33L on the left side in the figure is unlocked as the opening / closing body 33R on the right side is unlocked.

The solar cell 14 attached to the one opening / closing body 33 is electrically connected to the secondary battery 15 attached to the one housing 2 via a wiring 28 and the like. The secondary battery 15 is electrically connected to the electric locking / unlocking device 13 a attached to the plurality of opening / closing bodies 33 via the wiring 29 and the like. The wiring 29 is provided between the three casings 2 (between the assembled bodies 2E), the secondary battery 15 attached to the casing 2 of the assembled body 2E on the left side in the figure, and the respective assembled bodies on the center and the right side in the figure. The 2E electric locking / unlocking device 13a is electrically connected. At least a part of the wirings 28 and 29 may be arranged in the housing 2.
The wirings 26 and 29 electrically connect at least one of the solar cell 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.

In the example shown in FIGS. 5 and 6, the solar cell 14 is vertically arranged 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 and closing body 33 is opened and closed by a pair of double-sided opening / closing members 33. The opening / closing body 33 may be configured to be opened and closed in the same direction (see FIGS. 3 and 4).
