Embodiments for Carrying Out the Invention

[0014] Hereinafter, with reference to the accompanying drawings, preferred embodiments of the article storage device according to the present invention will be described in detail.

[0015] Figures 1 and 2 show an article storage device 1 which is an embodiment of the present invention, with Figure 1 being a front view showing the external configuration and Figure 2 being a front view showing the internal configuration.

[0016] The item storage device 1 illustrated here is, for example, a locker device used as a delivery locker or a vending machine that sells goods, and is equipped with a device body 2. In the following, the various components of the item storage device 1 will be described according to the directions shown in Figures 1 and 2.

[0017] The main body of the device 2 is a rectangular housing with a front opening 3 on its front, and has an insulating structure by incorporating insulating materials such as foamed urethane or vacuum insulation material. As shown in Figure 3, the front opening 3 in the main body of the device 2 is formed by framing an opening frame with an upper frame 4, a lower frame 5, and a pair of left and right vertical frames (outer edge frames) 6 around the perimeter, and then arranging a central frame 7 that connects the upper frame 4 and the lower frame 5 to divide the opening frame into left and right halves. In other words, there are two front openings 3 in the main body of the device 2, one on the left and one on the right. Hereinafter, the left front opening 3 will also be referred to as the left front opening 3a, and the right front opening 3 will also be referred to as the right front opening 3b.

[0018] Inside the main body 2 of the device described above, a storage chamber 8 is formed facing the front opening 3. This storage chamber 8 has a left storage area 8a corresponding to the left front opening 3a and a right storage area 8b corresponding to the right front opening 3b. A cooling unit (not shown) is also installed inside the main body 2, and the storage chamber 8 is cooled to below a predetermined temperature by the operation of this cooling unit.

[0019] In the storage room 8, the left storage area 8a and the right storage area 8b each have multiple shelves 10 arranged in multiple tiers (five in the example in Figure 3) along the vertical direction.

[0020] Figure 4 is a perspective view showing multiple shelves 10 and their surrounding structure provided in each storage area 8a, 8b. As shown in Figure 4, in each storage area 8a, 8b, the shelves 10 are supported by a pair of left and right support members 12, 13 provided on shelf columns 11 that are erected in a left-right pair manner, thereby the shelves 10 are installed between the shelf columns 11.

[0021] Figure 5 is a perspective view showing the pair of left and right support members 12 and 13 shown in Figure 4. As shown in Figure 5, the left support member (hereinafter also referred to as the first support member) 12 is constructed by processing sheet metal, for example, and is a long member with its longitudinal direction in the front-to-back direction. This first support member 12 is constructed by integrally molding a first support base 121, a first support left lower extension 122, a first support right lower extension 123, and a first support right extension 124.

[0022] The first support base 121 is a horizontally extending portion that extends along the front-rear direction. Multiple circular holes are formed in this first support base 121. The first support left lower extension 122 is a portion that extends downward from the left end portion of the first support base 121. Two first mounting pieces 122a are formed on the lower end edge of this first support left lower extension 122, projecting downward. The first support member 12 is provided on the left shelf column 11 by inserting these two first mounting pieces 122a into mounting holes (not shown) formed in the left shelf column 11.

[0023] The first support right lower extension 123 is the portion that extends downward from the right end portion of the first support base 121. The first support right extension 124 is a horizontal extension portion that extends to the right from the extended end portion of the first support right lower extension 123. The first support right extension 124 has a first locking hole 124a and two first connecting holes 124b formed in order from the front. The first locking hole 124a is a rectangular hole formed in the front end portion of the first support right extension 124. The first connecting holes 124b are rectangular holes that have a larger front-to-back dimension than the first locking hole 124a.

[0024] Furthermore, a first locking slit 125 is formed between the first protruding piece 124c and the first right lower extension 123 by bending a tongue-shaped first protruding piece 124c upward at the rear end portion of the first support right extension 124.

[0025] As shown in Figure 5, the right-side support member (hereinafter also referred to as the second support member) 13 is constructed by processing sheet metal, for example, and is a long, rectangular member with its longitudinal direction in the front-to-back direction. This second support member 13 is constructed by integrally molding a second support base 131, a second support right lower extension 132, a second support left lower extension 133, and a second support left extension 134.

[0026] The second support base 131 is a horizontally extending portion that extends along the front-rear direction. Multiple circular holes are formed in this second support base 131. The second support right lower extension 132 is a portion that extends downward from the right end portion of the second support base 131. Two second mounting pieces 132a are formed on the lower end edge of this second support right lower extension 132, projecting downward. The second support member 13 is provided on the right shelf column 11 by inserting these two second mounting pieces 132a into mounting holes (not shown) formed in the right shelf column 11.

[0027] The second support left lower extension 133 is the portion that extends downward from the left end portion of the second support base 131. The second support left extension 134 is a horizontal extension portion that extends to the left from the extended end portion of the second support left lower extension 133. The second support left extension 134 has a second locking hole 134a and two second connecting holes 134b formed in order from the front. The second locking hole 134a is a rectangular hole formed in the front end portion of the second support right extension. The second connecting holes 134b are rectangular holes that have a larger front-to-back dimension than the second locking hole 134a.

[0028] Furthermore, a second locking slit 135 is formed between the second protruding piece 134c and the second support's left lower extension 133 by bending a tongue-shaped second protruding piece 134c upward at the rear end portion of the second support's right extension.

[0029] By the way, reference numeral 14 in Figure 5 indicates a connecting plate. The connecting plate 14 is constructed, for example, by processing sheet metal, and is a long plate-like body with its longitudinal direction running horizontally. The left end of this connecting plate 14 is inserted into the first connecting hole 124b on the rear side, and the right end is inserted into the second connecting hole 134b on the rear side, thereby connecting the first support member 12 and the second support member 13. In other words, the first support member 12 and the second support member 13 are connected to each other via the connecting plate 14.

[0030] Figure 6 is a perspective view showing the shelf board 10. The shelf board 10 is constructed by processing multiple sheet metals and comprises a shelf board body portion 101 and a shelf board reinforcement portion 102. The shelf board body portion 101 is a substantially flat plate-like body in which the front end portion and both left and right ends are bent downwards, while the rear end portion is bent upwards. The top surface of this shelf board body portion 101 constitutes a mounting surface, and first locking pieces 1011 and 1012 are formed at the rear ends of both the left and right ends.

[0031] The first locking piece (hereinafter also referred to as the first left-side locking piece) 1011 formed at the rear end portion of the left end of the shelf board body portion 101 has a first left-side locking rear extension portion 1011a that protrudes toward the rear and a first left-side locking right extension portion 1011b that protrudes toward the right.

[0032] The first locking piece (hereinafter also referred to as the first right-side locking piece) 1012 formed at the rear end portion of the right end of the shelf board body portion 101 has a first right-side locking rear extension portion 1012a that protrudes toward the rear and a first right-side locking left extension portion 1012b that protrudes toward the left.

[0033] The shelf reinforcement part 102 is a member whose longitudinal direction is in the left-right direction and is attached to the lower surface of the shelf main body part 101. This shelf reinforcement part 102 improves the strength of the shelf 10. The shelf reinforcement part 102 has a second locking piece (hereinafter also referred to as the second left locking piece) 1021 that protrudes downward at the left end and a second locking piece (hereinafter also referred to as the second right locking piece) 1022 that protrudes downward at the right end.

[0034] The shelf board 10 having such a configuration is supported by the support members 12 and 13 as follows. As shown in Figure 7, the shelf board 10 is tilted downwards as it moves towards the rear, and the first left locking piece 1011 is inserted into the first locking slit 125 while the first right locking piece 1012 is inserted into the second locking slit 135. Then, as shown in Figure 8, by swinging the front end of the shelf board 10 downwards, the second left locking piece 1021 is inserted into the first locking hole 124a from above while the second right locking piece 1022 is inserted into the second locking hole 134a from above, so that the shelf board 10 is supported by the pair of left and right support members as shown in Figures 9 to 11.

[0035] In this case, when the first left-side locking piece 1011 is inserted into the first locking slit 125, the first left-side locking extension 1011a penetrates the first locking slit 125 and the first left-side locking right extension 1011b is positioned below the first protruding piece 124c. Also, when the first right-side locking piece 1012 is inserted into the second locking slit 135, the first right-side locking extension 1012a penetrates the second locking slit 135 and the first right-side locking left extension 1012b is positioned below the second protruding piece 134c.

[0036] As a result, the shelf board 10 is restricted from moving vertically and horizontally by inserting the first locking pieces 1011 and 1012 into the first locking slit 125 and the second locking slit 135. Furthermore, the shelf board 10 is restricted from moving forward and backward by inserting the second locking pieces 1021 and 1022 into the first locking hole 124a and the second locking hole 134a.

[0037] Furthermore, the shelf board 10 can be removed from the support members 12 and 13 by moving only its front end upward, causing it to gradually tilt upward as it moves forward, thereby releasing the second locking pieces 1021 and 1022 from the first locking hole 124a and the second locking hole 134a, and then moving it slightly backward, thereby releasing the first locking pieces 1011 and 1012 from the first locking slit 125 and the second locking slit 135.

[0038] As shown in Figures 2 and 12, storage modules 20 are placed on shelves 10 that are installed vertically in multiple tiers in each storage area 8a, 8b. More specifically, the storage modules 20 are placed on the upper surface (mounting surface) of the shelf body 101.

[0039] The storage module 20 is made of a resin material such as plastic, and has a rectangular module body 21 with an open front section, inside which up to four columns (not shown) are defined. The front section of this module body 21 is opened and closed by four module doors 22 corresponding to the maximum number of columns (four).

[0040] In such a storage module 20, the front end portion of a mounting piece 23 attached to the bottom surface of the module body 21 is bent downward, and this front end portion of the mounting piece is fastened to the front end surface of the shelf body portion 101 of the shelf board 10 via fastening members 24 such as screws, thereby allowing the module to be placed on the shelf board 10.

[0041] In this manner, the placement of the storage module 20 restricts the shelf board 10 from moving only its front end upward, causing it to gradually tilt upward as it moves forward. Consequently, the placement of the storage module 20 prevents the shelf board 10 from being separated from the pair of left and right support members 12 and 13.

[0042] The front end portion of the mounting piece 23 is covered by a cover member 30, as shown in Figure 13. This cover member 30 is made of, for example, sheet metal, and is a long, rectangular member with its longitudinal direction running in the left-right direction. Figure 14 is a perspective view showing the cover member 30 provided in the left storage area 8a. Note that the cover member 30 provided in the right storage area 8b is configured with the left-right direction reversed compared to the cover member 30 provided in the left storage area 8a. Therefore, in the following description, only the cover member 30 provided in the left storage area 8a will be explained, and the explanation of the cover member 30 provided in the right storage area 8b will be omitted. Regarding the left-right direction of the cover member 30, the left side, which is close to the vertical frame 6, will be referred to as the outside, and the right side, which is close to the central frame 7, will be referred to as the inside.

[0043] As shown in Figure 14, the cover member 30 is constructed by integrally molding a cover base 31, a lower end bent portion (see Figure 17) 32, an outer bent portion 33, and an inner bent portion 34.

[0044] The cover base 31 is a flat plate-shaped portion that extends along the left-right direction. This cover base 31 is large enough to cover the front end portion of the mounting piece 23. The lower end bent portion 32 is a portion that extends rearward from the lower end of the cover base 31. The outer bent portion 33 is a hook-shaped portion that extends rearward from the outer end of the cover base 31 and then gradually inclines forward as it moves outward. The inner bent portion 34 is a portion that extends rearward from the inner end of the cover base 31 and then extends inward.

[0045] Such a cover member 30 is provided in the left storage area 8a (device body 2) as follows: As shown in Figure 15, the outer bent portion 33 is inserted into a square hole 6a formed in the vertical frame 6, and as shown in Figure 16, the inner bent portion 34 is inserted into a notch 7a formed on the front surface of the central frame 7. In this way, the cover member 30 is engaged with the device body 2 and provided so that its movement in the front, back, left, right, and up and down directions is restricted.

[0046] As shown in Figure 17, the cover member 30 is placed on the upper surface of the module body 21 of the storage module 20, which is located below the mounting piece 23 and shelf board 10, to which the lower end bent portion 32 is to be covered. Furthermore, as shown in Figure 18, a lock cover 40 is attached to the front surface of the central frame 7 in a manner that covers the notch 7a, thereby positioning the cover member 30 in a state where the inner bent portion 34 is prevented from detaching from the notch 7a.

[0047] As described above, the cover member 30 is provided on the main body 2, thereby restricting the storage module 20, which has a mounting piece 23 whose front end is covered by the cover member 30, from being pulled forward. Although the storage module 20 is fastened to the shelf board 10 via the fastening member 24, even if the fastening force is insufficient, the cover member 30 will restrict it from being pulled forward.

[0048] The main body 2 of the above-mentioned device is provided with two outer doors 50 that open and close each front opening 3. Although not explicitly shown in the figure, these two outer doors 50 have an insulating structure by laying insulating material such as foamed urethane or vacuum insulation material between the outer and inner panels.

[0049] The left outer door 50 is pivotably mounted on the device body 2 at its left edge so as to open and close the left front opening 3a, and the right outer door 50 is pivotably mounted on the device body 2 at its right edge so as to open and close the right front opening 3b.

[0050] When the left outer door 50 swings in the closing direction, a portion of it engages with the locking portion 41 provided on the lock cover 40, thereby closing the left front opening 3a. Similarly, when the right outer door 50 swings in the closing direction, a portion of it engages with the locking portion 41 on the other lock cover 40 provided on the front of the central frame 7, thereby closing the right front opening 3b.

[0051] Incidentally, although not explicitly shown in the diagram, each outer door 50 is equipped with electrical components such as lamps indicating that items are available for sale. Therefore, a connecting wire 51 from the main unit 2 is connected to the electrical components of each outer door 50. As shown in Figure 19, the lower end of this connecting wire 51 is connected to the main unit 2, extends upward, then curves downward, then curves upward again, and its extended end is connected to each electrical component. In other words, the connecting wire 51 is arranged in a vertical loop along its length.

[0052] As shown in Figures 20 and 21, the lower frame 5 is composed of a first lower frame component 5a, which has recesses 5c formed in the lower center of the left front opening 3a and the lower center of the right front opening 3b, and two second lower frame components 5b which are detachably disposed in the recesses 5c of the first lower frame component 5a.

[0053] The recesses 5c of the first lower frame component 5a are located near the refrigerant lines that constitute the cooling unit, namely the refrigerant lines 55 that extend vertically between the storage chamber 8 and the machine chamber 9, which is located below the storage chamber 8.

[0054] The cooling unit is a conventionally known design, consisting of a compressor, condenser, expansion mechanism, and evaporator connected sequentially through refrigerant piping. The evaporator is located in the storage chamber 8, while the compressor, condenser, and expansion mechanism (excluding the evaporator) are located in the machine room 9. Therefore, the refrigerant piping 55 extending vertically between the storage chamber 8 and the machine room 9 is connected to both the inlet and outlet sides of the evaporator.

[0055] Furthermore, as shown in Figure 22, a first heating element 61 and a second heating element 62 for preventing condensation are laid on the upper frame 4, lower frame 5, a pair of vertical frames 6, and central frame 7 that constitute the left front opening 3a and the right front opening 3b of the device body 2.

[0056] The first heating element 61 is a heating means that generates heat when energized. This first heating element 61 is laid out as follows: Starting from the IN side, the portion of the lower frame 5 (first lower frame component 5a) that forms the lower edge of the right front opening 3b extends to the right so as to approach the right recess 5c, then folds back and extends to the left so as to move away from the recess 5c, and then extends upward along the central frame 7. After the central frame 7 has been extended upward, the portion of the upper frame 4 that forms the upper edge of the right front opening 3b extends to the right, and the right vertical frame 6 extends downward. After the right vertical frame 6 has been extended downward in this manner, the portion of the lower frame 5 (first lower frame component 5a) that forms the lower edge of the right front opening 3b extends to the left so as to approach the right recess 5c, then folds back and extends to the right so as to move away from the recess 5c. In this manner, the lower frame 5 is extended to the right, then the right vertical frame 6 is extended upward, followed by the upper frame 4 being extended to the left, and then the left vertical frame 6 being extended downward. In this manner, the left vertical frame 6 is extended downward, and then the portion of the lower frame 5 (first lower frame component 5a) that becomes the lower edge of the left front opening 3a is extended to the right so as to approach the left recess 5c, and then folded back and extended to the left so as to move away from the recess 5c. In this manner, the lower frame 5 is extended to the left, then the left vertical frame 6 is extended upward, followed by the portion of the upper frame 4 that becomes the upper edge of the left front opening 3a being extended to the right, and then the central frame 7 is extended downward. After the central frame 7 extends downward in this manner, the portion of the lower frame 5 (first lower frame component 5a) that becomes the lower edge of the left front opening 3a extends to the left so as to approach the left recess 5c, then folds back and extends to the right so as to move away from the recess 5c, and is connected to the OUT side.

[0057] The second heating element 62 is a heating means that generates heat when energized. This second heating element 62 is laid out as follows: it extends upward from the IN side between the first heating elements 61 in the central frame 7, then folds back and extends downward to connect to the OUT side.

[0058] As described above, according to the article storage device 1, which is an embodiment of the present invention, the shelf board 10 is supported by the support members 12 and 13 in such a state that the first locking pieces 1011 and 1012 are inserted into locking slits (first locking slit 125 and second locking slit 135) formed in the support members 12 and 13, thereby restricting movement in the vertical and horizontal directions, and the second locking pieces 1021 and 1022 are inserted into locking holes (first locking hole 124a and second locking hole 134a) formed in the support members 12 and 13, thereby restricting movement in the front-to-back direction. As a result, multiple shelf boards 10 can be mounted on the shelf column 11 without the need for screws or the like. This reduces the number of parts and thereby reduces manufacturing costs.

[0059] According to the above-described article storage device 1, the storage module 20 is fastened to the front end surface of the shelf board 10 via a fastening member 24, and the cover member 30 is engaged with the device body 2 at both left and right ends in such a manner that it covers the front surface of the mounting piece 23. This suppresses the exposure of the fastening member 24 and improves the aesthetic appearance.

[0060] Furthermore, since the cover member 30 is engaged with the device body 2 in a state where movement in the front / back, left / right and up / down directions is restricted, by having its outer bent portion 33 inserted into the square hole 6a of the vertical frame 6 and its inner bent portion 34 inserted into the notch 7a of the central frame 7, it is possible to restrict the storage module 20 from moving forward if the fastening force of the fastening member 24 becomes insufficient. In particular, by covering the notch 7a of the central frame 7 with the lock cover 40, it becomes possible to position the storage module 20 and the like more securely.

[0061] In addition to the effects described above, the above-mentioned article storage device 1 provides the following effects. Specifically, the first lower frame component 5a of the lower frame 5 has a recess 5c formed near the refrigerant pipeline 55 that passes through the storage chamber 8 and the machine chamber 9, and the second lower frame component 5b is detachably provided in the recess 5c. By removing the second lower frame component 5b, the refrigerant pipeline 55 can be exposed, and a part of the cooling unit can be easily removed from the device body 2, thereby facilitating maintenance work and the like.

[0062] According to the above-described item storage device 1, the connecting wiring 51 that connects the device body 2 and the electrical components of the outer door 50 is looped vertically along its length. This suppresses deformation of the connecting wiring 51 due to the swinging of the outer door 50, thereby extending its service life.

[0063] According to the above-described article storage device 1, since the first heating element 61 and the second heating element 62 are laid, it is possible to heat up to the vicinity of the recess 5c, and the central frame 7, which is the most prone to cooling, can be heated intensively, thereby effectively suppressing the occurrence of condensation.

[0064] Although preferred embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications can be made.

[0065] In the embodiment described above, the mounting piece 23 of the storage module 20 was fastened to the front end surface of the shelf board 10 by a fastening member 24 at its front end. However, in the present invention, the fastening member 24 may not be used.

[0066] In the embodiment described above, the upper frame 4, lower frame 5, pair of vertical frames 6, and central frame 7 of the device body 2 were fitted with a first heating element 61 and a second heating element 62. However, in the present invention, as shown in Figure 23, a heating element 63 may also be fitted.

[0067] The heating element 63 is composed of a heater wire portion 63a that generates heat when energized, and a lead wire portion 63b made of a material with high electrical conductivity, such as copper, and is laid out as follows.

[0068] Specifically, the portion of the lower frame 5 (first lower frame component 5a) that will become the lower edge of the right front opening 3b extends to the right so as to approach the right recess 5c, then folds back and extends to the left so as to move away from the recess 5c, and then the central frame 7 extends upward. After the central frame 7 has been extended upward, the portion of the upper frame 4 that will become the upper edge of the right front opening 3b extends to the right, and the right vertical frame 6 extends downward. After the right vertical frame 6 has been extended downward in this manner, the portion of the lower frame 5 (first lower frame component 5a) that will become the lower edge of the right front opening 3b extends to the left so as to approach the right recess 5c, then folds back and extends to the right so as to move away from the recess 5c. After the lower frame 5 has been extended to the right in this manner, the right vertical frame 6 extends upward, and then the upper frame 4 extends to the left, and then the left vertical frame 6 extends downward. After the left vertical frame 6 extends downward in this manner, the portion of the lower frame 5 (first lower frame component 5a) that becomes the lower edge of the left front opening 3a extends to the right so as to approach the left recess 5c, then folds back and extends to the left so as to move away from the recess 5c. After the lower frame 5 extends to the left in this manner, the left vertical frame 6 extends upward, and then the portion of the upper frame 4 that becomes the upper edge of the left front opening 3a extends to the right, and then the central frame 7 extends downward. After the central frame 7 extends downward in this manner, the portion of the lower frame 5 (first lower frame component 5a) that becomes the lower edge of the left front opening 3a extends to the left so as to approach the left recess 5c, then folds back and extends to the right so as to move away from the recess 5c, and is connected to the OUT side.

[0069] In such a heating element 63, the portion that is on the outer edge side of each frame 4, etc., that is, the portion that extends to the right away from the right-side recess 5c, is part of the lead wire portion 63b, and the portion that extends to the right away near the left-side recess 5c, passing through the vertical frame 6, the upper frame 4, and the vertical frame 6 is part of the lead wire portion 63b, and the remaining portion is the heater wire portion 63a.

[0070] According to this, by running the heater wire section 63a along the inner edge of each frame 4, etc., which is easier to cool, the occurrence of condensation can be suppressed. [Explanation of Symbols]
