Disclosure of Invention

The present disclosure provides a storage device provided with a door that is easily moved by its own weight to take out and put in articles.

The storage device of the present disclosure includes: a housing having an opening portion opened at a front surface; a pair of outer doors which openably close the opening in the width direction; a housing chamber formed in the case and capable of housing an article; and a door of the accommodation chamber, which is disposed on a front surface of the accommodation chamber, is supported rotatably about a virtual axis extending in a width direction, and closes the front surface of the accommodation chamber so as to be openable and closable. The door of the accommodating chamber is supported to be rotatable between an open position where the accommodating chamber is opened and a closed position where the accommodating chamber is closed. The center of gravity of the door of the accommodation chamber is set at the following position: this position makes it possible to hold the door of the accommodation chamber in the open position by its own weight by the center of gravity passing over an imaginary line passing through the shaft and extending in the gravitational direction when the door is rotated from the closed position to the open position. The door of the accommodating chamber is provided with: a door main body portion extending in a width direction; and a side wall portion supporting the door main body portion and extending in a radial direction from the virtual axis, wherein a grip portion extending in a width direction is formed at a lower portion of the door main body portion. The holding portion restricts rotation of the door of the accommodating chamber due to its own weight when the door of the accommodating chamber moves to the open position. A distance from the tip of the grip portion to the virtual axis is shorter than a distance from the virtual axis to the inner end of the outer door in a radial direction of the movement direction of the virtual axis.

In the storage device of the present disclosure, the door of the storage chamber rotatable about the axis extending in the width direction is moved to the open position beyond the virtual line extending in the gravity direction through the axis when rotated from the closed position to the open position, and therefore, when moved to the open position, is rotated to the open position side by the self weight due to the moment. Therefore, the door of the storage chamber can be held at the open position by the self weight, and the operator can easily take out and put in the article, compared with the case where the operator performs the operation while holding the door of the storage chamber at the open position.

(embodiment 1)

Hereinafter, embodiment 1 will be described with reference to fig. 1 to 9.

[1-1. Structure ]

[1-1-1. Structure of storage device ]

Fig. 1 is a perspective view of a storage device 1 according to embodiment 1.

The storage device 1 is a storage device for refrigerating/freezing capable of storing articles stored therein at normal temperature or a predetermined temperature. The storage device 1 can be used as a showcase for sales for displaying articles or as a locker for receiving articles. The storage device 1 is installed in a store such as a supermarket or a convenience store.

The housing device 1 includes a box-shaped case 2, and the case 2 includes a heat insulating wall. The housing 2 includes a machine chamber 3 at a lower portion and a storage chamber 4 above the machine chamber 3.

The machine room 3 houses therein a device constituting a refrigeration circuit such as a compressor, a condenser, an expander, and an evaporator, and the temperature of the storage room 4 is adjusted by driving the device.

An opening 4A that opens in the front is formed in the front surface of the storage chamber 4. The opening 4A is closed by a pair of outer doors (opening doors) 5 and 6 in the width direction so as to be openable and closable. The outer doors 5 and 6 are supported at the left and right outer ends of the opening 4A so that the upper and lower ends thereof can pivot via hinges. The outer doors 5, 6 are so-called side-by-side doors.

The outer doors 5 and 6 include: rectangular frames 5A, 6A; transparent plates 5B, 6B fitted into the frames 5A, 6A; and handles 5C, 6C provided at positions where the outer doors 5, 6 approach each other when the outer doors 5, 6 are closed. The storage device 1 is configured to be able to visually confirm the inside of the storage compartment 4 from the outside through the transparent plates 5B, 6B in a state where the outer doors 5, 6 are closed.

A touch panel 7 functioning as an input unit and a display unit for an operator or a user is provided on the front surface of the right outer door 6. The touch panel 7 is configured to display various information, and by touching a portion of the displayed information, various information such as setting information of the storage device 1 can be input.

An acquisition unit 8 is provided below the touch panel 7, and the acquisition unit 8 acquires authentication information for performing authentication processing of an operator or a user. The acquisition unit 8 acquires authentication information of an operator from a portable information terminal (smart phone or the like) held by the operator or the like, for example. Based on the authentication information, the electronic locks (not shown in fig. 1) of the outer doors 5 and 6 are unlocked and locked.

Fig. 2 is a perspective view of the housing device 1 according to embodiment 1, with illustration of the outer doors 5 and 6 omitted.

The housing 2 has a rear heat insulating wall 20, left and right heat insulating walls 21, 22, upper and lower heat insulating walls 23, 24, and upper and lower front walls 25, 26.

A plate-like deck plate (deck pan) 27 is disposed above the lower front wall 26. The interior of the housing 2 is divided up and down by a deck plate 27. Inside the housing 2, a machine room 3 is formed below the deck plate 27. Further, a storage room 4 is formed above the deck plate 27. An opening 4A is formed in the front surface of the storage chamber 4 by the surrounding shape of the left and right heat insulating walls 21, 22 and the upper and lower front walls 25, 26.

A cold air delivery pipe and an air recovery pipe, not shown, extending upward are provided at the rear of the deck plate 27. The cold air cooled in the machine room 3 is sent to the upper side of the storage room 4 by a cold air sending pipe, and is introduced into the storage room 4 by an upper fan (not shown). The cool air introduced into the storage chamber 4 cools the storage chamber 4 and then returns to the machine chamber 3 through the air recovery pipe. The cold air can circulate inside the housing 2.

Fig. 3 is a perspective view of the internal structure of the storage device 1 in embodiment 1.

As shown in fig. 3, pillar frames 41 extending in the up-down direction are arranged at four corners of the storage compartment 4. A pillar frame, so-called a center pillar 42, extending in the up-down direction is disposed at the widthwise center of the storage compartment 4. The center pillar 42 is disposed in a pair in front of and behind the storage compartment 4. The storage chamber 4 is divided into a left storage chamber 4L (see fig. 2) and a right storage chamber 4R (see fig. 2) by the center pillar 42. In the left and right storage compartments 4L, 4R, a plurality of net frames 43 (see fig. 3) in the form of net plates are supported between the center column 42 and the pillar frame 41. The net rack 43 is disposed at a predetermined interval in the vertical direction. Thus, a plurality of storage chambers 44 (see fig. 3) are formed in the storage chambers 4L, 4R with the net rack 43 as a bottom. An article can be disposed in the accommodation chamber 44. In the present embodiment, the housing chambers 44 are formed in 2 rows in the left-right direction and 6 layers in the up-down direction, but the number of the housing chambers 44 may be appropriately configured.

Fig. 4 is a perspective view of the right inner door unit 51 in embodiment 1, and shows a state in which the inner door 61 is moved to the closed position. Fig. 5 is a perspective view of the right inner door unit 51 in embodiment 1, and shows a state in which the inner door 61 is moved to the open position. Fig. 6 is a longitudinal sectional view of the storage device 1 in embodiment 1, and shows a rotational state of the inner door 61. In fig. 6, the uppermost inner door 61 is shown in a state of being moved to the open position, the lowermost inner door 61 is shown in a state of being moved to the closed position, and the intermediate inner door 61 is shown in a state of being rotated between the open position and the closed position.

The inner door unit 51 is disposed in each of the accommodating chambers 44 of the left and right storage chambers 4L, 4R. The structure of the inner door unit 51 is substantially symmetrical between the left storage room 4L and the right storage room 4R, but the basic structure is the same, and therefore, the inner door unit 51 on the right side will be described below.

As shown in fig. 4 and 5, the inner door unit 51 has a plate-like top plate 52 extending in the left-right direction. Rectangular plate-shaped side plates 53, 54 are supported at both left and right ends of the top plate 52. The left and right side plates 53, 54 are connected to connecting frames 56, 57 extending in the front-rear direction. As shown in fig. 3, the left and right inner connecting frames 56 are supported by the front and rear center posts 42. The left and right outer connecting frames 57 are supported by the front and rear pillar frames 41. Thereby, the inner door unit 51 is disposed in the accommodation chamber 44. The front opening 44A of the housing chamber 44 is formed by the surrounding shape formed by the top plate 52, the left and right side plates 53, 54, and the net frame 43.

An inner door (door of the accommodation chamber) 61 is disposed in the front opening 44A. The inner door 61 includes a door body portion 62 extending in a rectangular shape in the left-right direction. Inner side wall portions 63 (see fig. 5) extending rearward are formed at the left and right inner ends of the door main body portion 62. Outer side wall portions 64 (see fig. 4) extending rearward are formed at the left and right outer ends of the door main body portion 62.

The inner side wall 63 and the outer side wall 64 are formed in a trapezoidal plate shape, and the lower edges 63A and 64A are inclined upward as they progress rearward of the storage device 1 in a state where the inner door 61 is closed. Rear ends of the inner side wall 63 and the outer side wall 64 of the storage device 1 are rotatably supported by the rotation shafts 53A and 54A extending in the left-right direction. The rotation shafts 53A, 54A are supported by the side plates 53, 54. The rotation shafts 53A and 54A are disposed on the same axis. The inner door 61 is rotatably supported about rotation shafts 53A and 54A as rotation centers (virtual axes) L0.

Accordingly, the inner door 61 is rotated about the rotation shafts 53A, 54A between the closed position shown in fig. 4, in which the front opening 44A is closed, and the open position shown in fig. 5, in which the front opening 44A is opened. Since the inner door 61 is rotatably supported by the inner side wall 63 and the outer side wall 64 extending in the radial direction of the moving direction, the inner door 61 is disposed above the housing chamber 44 when moving to the open position, and the inner door 61 can be housed in the housing chamber 44 in a state of facing the lower surface of the top plate 52.

The stopper pins 53B, 54B are supported on the inner surfaces of the side plates 53, 54 of the inner door unit 51 in correspondence with the front lower sides of the rotation shafts 53A, 54A. The stopper pins 53B, 54B protrude toward the inside of the accommodation chamber 44 with respect to the side wall portions 63, 64. The stopper pins 53B and 54B are disposed on the same axis. The stopper pins 53B, 54B restrict the rotation of the inner door 61 due to the self weight when contacting the lower edges 63A, 64A of the inner door 61. Thereby, the inner door 61 is held in the closed position closing the front opening 44A of the accommodating chamber 44.

A grip portion 62A extending in the width direction is formed at a lower portion of the door main body portion 62. As shown in fig. 6, the grip 62A is inclined forward as it advances downward in a side view. As shown in the lower layer of fig. 6, the grip 62A protrudes forward from the front opening 44A in the closed position. The grip portion 62A is formed in a rectangular shape in the left-right direction, and a notch portion 62A1 is formed in the left-right central portion thereof so as to be notched. Can contact the inner surface side of the grip portion 62A through the cutout portion 62A1.

The grip 62A extends sufficiently long below the front opening 44A of the housing chamber 44, and closes the front opening 44A. The distance from the distal end of the grip 62A to the rotation shafts 53A, 54A is smaller than the distance from the rotation shafts 53A, 54A to the inner ends L1 of the outer doors 5, 6 in the radial direction of the movement direction of the rotation shafts 53A, 54A. Therefore, even if the inner door 61 rotates in a state where the outer doors 5, 6 are closed, as shown in the middle layer of fig. 6, the inner door 61 does not contact with the outer doors 5, 6. This results in the following structure: even if a force is naturally applied to the inner door 61 by vibration or the like, the inner door moves from the open position to the closed position, and no load such as damage is applied to the outer door 6.

When the grip 62A is moved to the open position, it contacts the top plate 52, and the rotation of the inner door 61 due to its own weight is restricted. Thereby, the inner door 61 is held in the open position of the open front opening 44A.

Fig. 7 is a perspective view of the right inner door unit 51 of embodiment 1, as viewed from the left and right inner sides, and shows a state in which the inner door 61 is moved to the closed position. Fig. 8 is a perspective view of the right inner door unit 51 of embodiment 1, as viewed from the left and right inner sides, and shows a state in which the inner door 61 is moved to the open position.

An arc-shaped hole 53C penetrating the side plate 53 in the thickness direction is formed in the side plate 53 on the left and right inner sides. The arc hole 53C is formed in an arc shape centered on the rotation shaft 53A. A connection shaft 53D extending in the left-right direction is disposed in the arc hole 53C. The connection shaft 53D is fixed to the side wall 63 inside the inner door 61 through the arc-shaped hole 53C.

A lock member 66 having a curved plate shape is fixed to the inner end side of the connecting shaft 53D in the left-right direction. The lock member 66 includes: a fixing portion 67 extending along the side plate 53; a click plate portion 68 extending inward in the left-right direction from the upper end of the fixing portion 67; and a guide portion 69 bent downward from the inner end of the engagement plate portion 68 in the left-right direction.

The rear end portion of the fixing portion 67 of the lock member 66 is rotatably supported by the rotation shaft 53A. In addition, the fixing portion 67 is connected to the connection shaft 53D at the front end portion. Therefore, the lock member 66 is rotatable about the rotation shaft 53A as the rotation center L0, and is rotatable integrally with the inner door 61 via the connection shaft 53D.

Here, as shown in fig. 6, an imaginary line passing through the rotation shafts 53A and 54A and extending in the gravitational direction is referred to as a gravity center line L2. In this case, the center of gravity 61G of the inner door 61, that is, the center of gravity 61G of the whole of the inner door 61 and the locking member 66 that integrally rotates, is set so that the center of gravity 61G passes over the center of gravity L2 when the inner door 61 moves from the closed position to the open position. That is, the inner door 61 is configured to rotate toward the closed position by its own weight when the center of gravity 61G is located on the front side of the gravity center L2, and to rotate toward the open position by its own weight when the center of gravity 61G is located on the rear side of the gravity center L2.

Fig. 9 is a schematic diagram of the electric lock mechanism 71 in embodiment 1.

An electric locking mechanism 71 is disposed on the rear upper side of the locking member 66. The electric locking mechanism 71 is fixed to the side plate 53 via an electric mounting frame 81 (see fig. 7 and 8). The electric lock mechanism 71 has a cylindrical electromagnet body 72. The electromagnet body 72 is fixed to the housing frame 73. The housing frame 73 is formed in an L-shape in cross section, and includes a base 73A and an extension 73B extending from the upper end of the base 73A in a curved manner in the left-right direction. A bottom 72A of the electromagnet body 72 is fixed to the base 73A. The extension 73B is disposed along the cylindrical side surface of the electromagnet body 72, and extends in the axial direction of the electromagnet body 72. A flat plate-like stopper plate 74 is swingably supported by a hinge mechanism 75 at the end of the extension 73B. The stopper plate 74 is made of a material that can be magnetically attracted, for example, iron. The stopper plate 74 is disposed in a state of facing the attraction portion 72B of the electromagnet main body 72 based on the magnetic force. The stopper plate 74 is supported so as to be capable of swinging in a near-to-separating manner with respect to the suction portion 72B.

One end of a tension spring 76 as an example of a biasing member is connected to the base end portion of the stopper plate 74. The other end of the tension spring 76 is coupled to the base 73A of the housing frame 73. The tension spring 76 is disposed between the stopper plate 74 and the housing frame 73 in an elastically deformed state.

With the electromagnet main body 72 turned OFF (OFF) and not energized, the base of the stopper plate 74 is pulled by the elastic force of the tension spring 76, and therefore, the tip end portion side of the stopper plate 74 is separated from the suction portion 72B of the electromagnet main body 72. Thus, with the electromagnet body 72 off and not energized, the stopper plate 74 moves to the locked position shown by the solid line in fig. 9. When the electromagnet main body 72 is turned ON (ON) and energized, the stopper plate 74 is attracted by the attraction portion 72B against the elastic force of the tension spring 76 by electromagnetic force, and moves to the release position shown by the broken line in fig. 9.

A pair of front and rear protruding portions 74A (see fig. 7) are formed on the distal end side of the stopper plate 74 so as to correspond to both end portions of the side of the stopper plate 74. The protruding portion 74A is configured such that the stopper plate 74 can enter rearward and upward with respect to the engagement plate portion 68 of the lock member 66. The stopper plate 74 can be abutted against both end sides of the edge of the engagement plate portion 68, and can be abutted against the edge of the engagement plate portion 68 more widely than in the case where the engagement plate portion is abutted against the edge at a point.

The stopper plate 74 of the electric lock mechanism 71 is configured to retract from the rotation region of the lock member 66 by turning on the electromagnet main body 72, and to be able to enter the rotation region of the lock member 66 by turning off the electromagnet main body 72.

The electric lock mechanism 71 of the present embodiment is a so-called solenoid in which the stopper plate 74 is moved by the tension spring 76 and the electromagnet body 72.

The electric locking mechanism 71 is fixed to the electric mounting frame 81. The electrical mounting frame 81 is a bent plate-like frame. The electrical mounting frame 81 has an upper extension 82 fixed to the center post 42 of the inner door unit 51. The upper extension 82 extends inward in the left-right direction. A plate-shaped solenoid fixing portion 83 extending downward is formed at the left and right inner ends of the upper extension portion 82. A lower extension 84 bent in a stepped manner toward the inner door 61 side and extending downward is formed at the lower end of the solenoid fixing portion 83. The lock member 66 is disposed on the left-right direction inner side of the lower extension 84. In the electrical mounting frame 81, the solenoid fixing portion 83 protrudes to the left and right most inward. The solenoid fixing portion 83 is set to a protrusion amount smaller than half the left-right width of the center post 42 with respect to the side plate 53.

A second electrical mounting frame 91 having a left-right width and extending downward is fixed to the lower extension 84. A guide lamp 92 is supported on the front surface of the second electrical mounting frame 91. The guide lamp 92 is constituted by, for example, an LED (Light Emitting Diode: light emitting diode) light source. For example, when receiving an article, the guide lamp 92 of the article accommodation chamber 44 is turned on, whereby the article accommodation chamber 44 of the subject can be displayed to the operator.

Since the electrical mounting frame 81 and the second electrical mounting frame 91 are disposed between the front and rear center posts 42, the space between the front and rear center posts 42 that is likely to be a dead angle can be effectively utilized.

[1-2. Action ]

The operation of the storage device 1 configured as described above will be described below.

In the storage device 1, the articles are stored in a state where the outer doors 5 and 6 are closed. When authentication information of the operator is authenticated via the acquisition unit 8, the outer doors 5 and 6 are unlocked, the outer doors 5 and 6 can be opened, and the inner door unit 51 of the object article of the operator is controlled.

That is, in the inner door unit 51 of the object article, the guide lamp 92 is turned on, and the object accommodating chamber 44 is guided by the operator. Further, the electric locking mechanism 71 is operated, and the target inner door 61 is unlocked.

In the inner door unit 51, the inner door 61 is held in the closed position. The operator can move to the open position by grasping the grasping portion 62A or the like of the inner door 61 and rotating the inner door 61 upward. At this time, the center of gravity 61G of the inner door 61 moves to the open position across the center of gravity L2. Therefore, even if the operator leaves his or her hand from the inner door 61, the grip 62A is held in contact with the top plate 52 by a moment, and the inner door 61 is held in the open position by its own weight. Therefore, even if the operator does not continue to touch with his or her hand, the inner door 61 can be maintained in an opened state, and the operator can easily take out the article.

After taking out the article, when the operator moves the inner door 61 from the open position to the closed position, the center of gravity 61G of the inner door 61 passes over the center of gravity line L2. Therefore, even if the operator leaves his/her hand, the lower edges 63A, 64A of the inner door 61 are held in contact with the stopper pins 53B, 54B, and the inner door 61 is held in the closed position by its own weight.

Here, when the housing device 1 determines that the predetermined job end condition is satisfied, the electric lock mechanism 71 is turned off. When the electric locking mechanism 71 is disconnected, the stopper plate 74 enters the rear of the locking member 66 that is moved to the closed position by the elastic force of the tension spring 76. Therefore, even if the inner door 61 is to be opened, the movement of the inner door 61 is restricted by the contact of the lock member 66 with the stopper plate 74, and thus the inner door 61 is locked in an immovable state.

When the electric lock mechanism 71 is turned off in a state in which the operator does not move the inner door 61 to the closed position but moves the inner door 61 to the open position, the side surface of the stopper plate 74 contacts the side surface of the guide portion 69 of the lock member 66 in a surface contact state. Therefore, the stopper plate 74 cannot enter the rotation region of the locking member 66, and is thus not locked. In this case, the inner door 61 can be moved to the closed position, and the inner door 61 can be moved to the closed position with the stopper plate 74 being brought into contact with the guide portion 69. In the case where the inner door 61 is moved to the closed position, the locking member 66 is moved to the closed position, and thus, the stopper plate 74 enters behind the locking member and the inner door 61 is locked.

Further, even if the operator does not close the inner door 61 but closes the outer doors 5, 6, as shown in the upper layer of fig. 6, the inner door 61 is held above the inside of the accommodating chamber 44, and therefore, the inner door 61 does not interfere with the outer doors 5, 6. Thus, the outer doors 5, 6 can be closed. As shown in the lower layer of fig. 6, when the inner door 61 is moved to the closed position, the outer doors 5 and 6 can be closed. Therefore, the inner door 61 is a simple structure that rotates by its own weight, and when an operator releases his or her hand from the inner door 61, the inner door 61 moves to either one of the open position and the closed position, so that the outer doors 5 and 6 can be closed without interfering with the inner door 61.

[1-3. Effect etc. ]

As described above, in the present embodiment, the storage device 1 includes the refrigerant circuit, and the storage device 1 includes: a case 2 having an opening 4A opened at a front surface; a housing chamber 44 formed in the case 2 and capable of housing an article; and an inner door 61 disposed on the front surface of the housing chamber 44 and supported rotatably about shafts 53A and 54A having a rotation center L0 extending in the width direction, and closing the front surface of the housing chamber 44 so as to be openable and closable. The inner door 61 is supported rotatably between an open position where the accommodating chamber 44 is open and a closed position where the accommodating chamber 44 is closed. The center of gravity 61G of the inner door 61 is set at the following position: this position is such that, when the inner door 61 is rotated from the closed position to the open position, the center of gravity 61G passes over the center of gravity line L2 that passes through the shafts 53A, 54A and extends in the gravitational direction. Accordingly, the position of the center of gravity 61G is different between the closed position and the open position with respect to the center of gravity L2, and therefore, the center of gravity can be rotated by the moment to one of the closed position and the open position. Therefore, when the inner door 61 is moved to the open position, the inner door 61 can be held at the open position by its own weight, and the operator can easily take out and put in the article as compared with a case where the operator performs the operation while holding the inner door 61 at the open position.

As in the present embodiment, the storage device 1 includes outer doors 5 and 6 supported by the case 2 and closing the opening 4A so as to be openable and closable. The inner door 61 includes: a door main body portion 62 extending in the width direction; and side wall portions 63, 64 supporting the door main body portion 62 and extending radially from the shafts 53A, 54A. The inner door 61 may be disposed on the front surface of the housing chamber 44 when moved to the closed position, and may be disposed above the interior of the housing chamber 44 when moved to the open position. Accordingly, since there is no need to secure an arrangement space for holding the inner door 61 between the outer doors 5 and 6 and the housing chamber 44, the outer doors 5 and 6 can be closed in a state where the inner door 61 is moved to the open position or the closed position. Therefore, compared to a configuration in which the inner door 61 is opened and closed outside the housing chamber 44, the housing chamber 44 can be made to be of a size that allows access to the outer doors 5 and 6, and the mounting capacity of the housing chamber 44 can be easily ensured.

As in the present embodiment, the lock member 66 provided to the inner door 61 and the electric lock mechanism 71 engaged with the lock member 66 so as to be able to be engaged with and disengaged from each other may be provided. Therefore, the inner door 61 can be locked by the electric control.

As in the present embodiment, the electric lock mechanism 71 may be disposed on the rear surface side of the center pillar 42, and the center pillar 42 may be provided to vertically extend to define the opening 4A. Therefore, by disposing the electric locking mechanism 71 on the rear surface side of the center pillar 42 which is likely to be a dead angle, the space on the rear surface side of the center pillar 42 can be effectively utilized. Further, since the electric locking mechanism 71 is not disposed in the housing chamber 44, the mounting capacity of the housing chamber 44 can be easily ensured.
