[0007] Issues to be Solved by Utility Models

[0008] In the case of a seat of a vehicle carrying a cold-insulated box or a thermal-insulated box, it is necessary to place the cold-insulated box or the thermal-insulated box stably so that the cold-insulated box or the thermal-insulated box does not tip over due to cornering or braking.

[0009] In the case of a seat of a vehicle carrying a cold-keeping box or a thermal-keeping box, if the cold-keeping box or the thermal-keeping box is held by a seat belt so as to be easily opened and closed from a driver's seat, the usability is high.

[0010] When a hook portion is provided on a cold-insulation box or a heat-insulation box having a handle, it is considered that the hook portion becomes difficult to carry due to the positional relationship with the handle, and the usability is deteriorated.

[0011] If the housing is recessed inwardly by a large amount in order to provide the hook portion in the cold-insulation box or the heat-insulation box, the storage space becomes small, or the amount of the heat-insulating material becomes small, thereby reducing the cold-insulation or heat-insulation performance.

[0012] The pair of left and right handles of a cold or thermal box are easy to carry with both hands, but not suitable for carrying with one hand, so there is room for improvement in terms of easy carrying. The total weight of a cold or thermal box varies greatly depending on the contents, so it is convenient to carry with one hand or with both hands.

[0013] The present invention aims to solve at least any one of the following problems 1 to 4.

[0014] Problem 1: Provide a cold or warm box that can be stably placed on a seat of a vehicle.

[0015] Topic 2: Provide cool or warm boxes that are easy to use.

[0016] Problem 3: Provide a cold-insulation box or a warm-insulation box that can suppress a reduction in storage space and a decrease in cold-insulation or heat-insulation performance due to provision of a hook portion.

[0017] Topic 4: Provide cold boxes or heat storages that are easy to transport.

[0134] like Figure 1 , Figure 5 As shown in FIG. 1 and FIG. 2 , the cold box 1001 has a pair of left and right hook portions 100 .

[0135] The left and right hooks 100 are of the same shape, for example, a resin molded body, and are positioned in the same front-to-back and vertical directions. The hooks 100 are open at the top. The hooks 100 extend upward from the center of the cold box 1001 in the vertical direction. Specifically, Figure 6 As shown in FIG. 1 , the hook portion 100 extends upward from the center line X in the vertical direction of the cold box 1001. The hook portion 100 may be located above the center line X.

[0136] The left and right hook portions 100 are respectively provided on the left side surface of the left outer box 12 and the right side surface of the right outer box 13 at positions lower than the left and right handle portions 21. The left side surface of the left outer box 12 and the right side surface of the right outer box 13 are examples of the outer surface and the side surface of the housing, and are also examples of portions intersecting the direction (left-right direction) in which the first hinge mechanism 25 extends.

[0137] The hook portion 100 at least partially overlaps the front-rear direction range of the handle portion 21. The left outer box 12 and the right outer box 13 have inclined portions 12b and 13b above the hook portion 100, which expand outward as they go upward.

[0138] like Figure 2 As shown in Fig. 8 (A) and Fig. 8 (B), the hook portion 100 has a base portion 101, a protruding portion 102, a vertical portion 103, a first bridge portion 104, and a second bridge portion 105. The protruding portion 102, the vertical portion 103, and the first bridge portion 104 constitute a first hook portion. The second bridge portion 105 constitutes a second hook portion.

[0139] First, the right hook portion 100 will be described.

[0140] The base 101 is a plate-shaped portion extending in the front-back direction and being substantially perpendicular to the left-right direction. The right outer box 13 has a recess 13a for arranging the base 101. A fastener 111 and a fastener holding member 112 for holding the fastener 111 are provided on the inner side of the front and rear parts of the recess 13a, respectively. The fastener 111 and the fastener holding member 112 are made of metal, for example. The hook portion 100 on the right side is fixed to the right outer box 13 by screws 110 respectively penetrating the front and rear parts of the base 101 and screwed with the fastener 111.

[0141] A pair of front and rear protrusions 102 extend from the lower end of the front end side and the lower end of the rear end side of the base 101 in the right direction, that is, in a manner of protruding (leaving) outward from the right side surface of the right outer box 13. A pair of front and rear upright portions 103 extend upward from the right ends of the front and rear protrusions 102. The first bridge portion 104 is an inverted U-shape when viewed from the right, and bridges the upper ends of the front and rear upright portions 103. The upright portion 103 and the first bridge portion 104 are plate-shaped portions extending in a manner opposite to the right side surface of the right outer box 13. The second bridge portion 105 bridges the front and rear upright portions 103 in the front-to-back direction at a position lower than the first bridge portion 104. The second bridge portion 105 is shaped so that at least the middle portion protrudes (extends) to the right, and extends from the upright portion 103 in a manner such that at least the middle portion leaves the right side surface of the right outer box 13.

[0142] Next, the left hook portion 100 will be described.

[0143] The base 101 is a plate-shaped portion extending in the front-back direction and substantially perpendicular to the left-right direction. The left outer box 12 has a recess 12a for arranging the base 101. A fastener 111 and a fastener holding member 112 for holding the fastener 111 are provided on the inner side of the front and rear of the recess 12a, respectively. The fastener 111 and the fastener holding member 112 are made of metal, for example. The hook portion 100 on the left side is fixed to the left outer box 12 by screws 110 respectively penetrating the front and rear of the base 101 and screwed with the fastener 111.

[0144] A pair of front and rear protrusions 102 extend from the lower end of the front end side and the lower end of the rear end side of the base 101 in the left direction, that is, in a manner of protruding (leaving) outward from the left side surface of the left outer box 12. A pair of front and rear upright portions 103 extend upward from the left ends of the front and rear protrusions 102. The first bridge portion 104 is an inverted U-shape when viewed from the left, and bridges the upper ends of the front and rear upright portions 103. The upright portion 103 and the first bridge portion 104 are plate-like portions extending in a manner opposite to the left side surface of the left outer box 12. The second bridge portion 105 bridges the front and rear upright portions 103 in the front-to-back direction at a position lower than the first bridge portion 104. The second bridge portion 105 is shaped so that at least the middle portion protrudes (extends) to the left, and extends from the upright portion 103 in a manner such that at least the middle portion leaves the left side surface of the left outer box 12.

[0145] like Figure 5 As shown, the protruding length L1 of the right hook portion 100 relative to the right side surface of the right outer box 13 is less than the protruding length L2 of the right handle portion 21 relative to the right side surface of the right outer box 13. Although omitted from the figure, the protruding length of the left hook portion 100 relative to the left side surface of the left outer box 12 and the protruding length of the left handle portion 21 also have the same relationship.

[0146] Fig. 9 1 is a perspective view showing a state where a cold box 1001 is placed on a passenger seat 200 of a vehicle and is held by a seat belt 201. The passenger seat 200 is an example of a seat other than a driver's seat. Fig. 9 As shown, when the cold box 1001 is placed on the passenger seat 200 with the first hinge mechanism 25 and the second hinge mechanism 26 located on the side opposite to the driver's seat, the right hook portion 100 faces the front side of the vehicle. In this state, the seat belt 201 is hooked from above to the right hook portion 100, so that the cold box 1001 can be held on the passenger seat 200.

[0147] also, Fig. 9This is an example of placing a cold box 1001 on the passenger seat 200 located on the left side of the driver's seat. Although not shown in the figure, when the cold box 1001 is placed on the passenger seat located on the right side of the driver's seat, when the first hinge mechanism 25 and the second hinge mechanism 26 are located on the side opposite to the driver's seat, the left hook portion 100 faces the front side of the vehicle. In this state, by hooking the seat belt to the left hook portion 100 from above, the cold box 1001 can be held on the passenger seat located on the right side of the driver's seat.

[0148] Fig.10 yes Fig. 9 The main part cross-sectional view of the state shown is a main part cross-sectional view observed from the same cross section as FIG. 8(A). Fig.10 As shown, the protrusion 102, the upright portion 103, and the first bridge portion 104 constituting the first hooking portion extend in a manner opposite to the right side surface of the right outer box 13 (or the left side surface of the left outer box 12), and can hook and pass the seat belt 201 between the right side surface of the right outer box 13 (or the left side surface of the left outer box 12).

[0149] Fig.11 is from Fig. 9 A three-dimensional diagram of a state in which the first cover 6 is opened. Fig. 9 In the state, the handle portion 6a of the first cover body 6 is located on the driver's seat side, so that Fig.11 As shown, it is easy to open the first cover 6 from the driver's seat, and it is also easy to take out and put in the items in the cold box 1001.

[0150] FIG. 12(A) shows a state where a small object storage container 117 is hooked on the second bridge portion 105. FIG. 12(B) shows a state where a lamp 119 is hooked on the second bridge portion 105 via a tool buckle 118. As shown in these figures, the second bridge portion 105 can be used to hook various objects. Fig. 9 As shown in FIG. 12(A) and FIG. 12(B), even when the seat belt 201 is hooked on the hook portion 100, an article can be hooked on the second bridge portion 105 as shown in FIG. 12(A) and FIG. 12(B).

[0151] Fig.13 This is a simplified block diagram of the mechanical structure of the cold box 1001. The cold box 1001 includes a compressor 41 as a cooling mechanism, a condenser 42, a capillary tube 43 (capillary tube), a refrigerant tube 44, a right refrigerant tube 45R, a left refrigerant tube 45L, a valve V1, and a valve V2. The compressor 41, the condenser 42, and the capillary tube 43 are provided in the second main body 4.

[0152] The compressor 41 has a motor, compresses the refrigerant, and outputs (discharges) it as a high-temperature and high-pressure gas. The condenser 42 releases the heat of the refrigerant output from the compressor 41 and discharges the refrigerant as a liquid. The capillary tube 43 creates resistance to the flow of the refrigerant liquefied by the condenser 42, reduces the pressure, and sends it to the inlet side of the valve V1 and valve V2 of the subsequent stage. The capillary tube 43 also forms a part of the refrigerant pipe.

[0153] The right refrigerant pipe 45R is provided corresponding to the right chamber 8R, and the left refrigerant pipe 45L is provided corresponding to the left chamber 8L. The right refrigerant pipe 45R and the left refrigerant pipe 45L are respectively arranged along Figure 1 and Figure 2 The right side member 16R and the left side member 16L extend from the outer surface thereof and merge at their front ends. The refrigerant pipe 44 connects the confluence of the right refrigerant pipe 45R and the left refrigerant pipe 45L to the inlet of the compressor 41. The refrigerant takes heat from the storage chamber 8 and evaporates to become a gas while passing through the surrounding of the storage chamber 8.

[0154] The right refrigerant pipe 45R and the left refrigerant pipe 45L are independent of each other. That is, the right refrigerant pipe 45R is provided to mainly cool the right chamber 8R, and the left refrigerant pipe 45L is provided to mainly cool the left chamber 8L.

[0155] The valve V1 and the valve V2 are solenoid valves, each having one flow path that can be connected to the outlet side and one flow path that can be connected to the inlet side (1in 1out type). The valve V1 and the valve V2 are connected to the right refrigerant pipe 45R and the left refrigerant pipe 45L, respectively, and can independently adjust (open and close) the flow of the refrigerant in the right refrigerant pipe 45R and the left refrigerant pipe 45L.

[0156] Fig.14 is a circuit diagram of the cold box 1001. Fig.14 In the diagram, the two battery packs 29 are divided into battery packs 29a and 29b.

[0157] The DC power supply 90 is, for example, a solar power generation device, and supplies DC power to the external power input terminal 28. Alternatively, the DC power supply 90 is, for example, an AC adapter, connected to an external AC power supply (not shown), converts AC power into DC power (for example, DC 12V), and supplies the DC power to the external power input terminal 28. Alternatively, the DC power supply 90 is, for example, an on-board power supply (on-board battery), and supplies DC power to the external power input terminal 28.

[0158] The compressor drive circuit 48 is a circuit that adjusts (changes) the rotation speed of the compressor 41 and is an example of an internal output changing circuit. By changing the rotation speed of the compressor 41 by the compressor drive circuit 48, the power consumption of the compressor 41 can be changed.

[0159] The cold box 1001 has a microcomputer 81 as an operation control unit, a microcomputer 82 as a charging control unit, a control power supply 83, a speed setting circuit 84, a shunt resistor 85, battery voltage detection circuits 86a, 86b, a DC power supply voltage detection circuit 86c, a charging circuit 88, and a shunt resistor 89 on a control circuit substrate 80.

[0160] Microcomputers 81 and 82 are control units for controlling the overall operation of cold box 1001, and function as control units for controlling the power supply to compressor 41 and the charging of battery packs 29a and 29b. Microcomputers 81 and 82 may not be separate from each other, but may be a single microcomputer (microcontroller).

[0161] The control power supply 83 converts the input voltage from the DC power supply 90 or the battery pack 29 a or 29 b into a power supply voltage (eg, 5 V) for the microcomputers 81 , 82 and the like, and supplies the power supply voltage to the microcomputers 81 , 82 and the like.

[0162] The battery voltage detection circuits 86a and 86b send detection signals corresponding to the voltages of the battery packs 29a and 29b, respectively, to the microcomputer 82. The DC power supply voltage detection circuit 86c sends a detection signal corresponding to the voltage of the DC power supply 90 to the microcomputer 81.

[0163] The microcomputer 81 controls the overall cooling and heating operations in the cold box 1001. The microcomputer 81 controls the on / off of the switch element Q3 provided in the current path of the compressor drive circuit 48, and controls the driving and stopping of the compressor 41. The microcomputer 81 sends a speed determination signal to the compressor drive circuit 48 via the speed setting circuit 84, and controls the speed of the compressor 41.

[0164] The microcomputer 81 receives the operation on the setting unit 60 as an electric signal, and controls the display in the setting unit 60. The microcomputer 81 controls the opening and closing of the valves V1 and V2, and controls the flow of the refrigerant in the right refrigerant pipe 45R and the left refrigerant pipe 45L.

[0165] The cold box 1001 has heaters 51L and 51R provided corresponding to the left chamber 8L and the right chamber 8R. The heaters 51L and 51R are, for example, line heaters, and are provided so as to cover the left refrigerant pipe 45L and the right refrigerant pipe 45R, respectively. The microcomputer 81 controls the on and off of the switching elements Q4 and Q5 provided in the current paths of the heaters 51L and 51R, respectively, and controls the driving of the heaters 51L and 51R individually.

[0166] The microcomputer 81 detects the temperature (current temperature) of the left chamber 8L and the right chamber 8R based on output signals of temperature sensors 55L and 55R such as thermistors provided corresponding to the left chamber 8L and the right chamber 8R.

[0167] The microcomputer 81 detects the drive current of the compressor 41 and the drive currents of the heaters 51L and 51R based on the voltage of the shunt resistor 85. The shunt resistor 85 is a module formed by collecting resistors connected in series with the switching elements Q3 to Q5. The microcomputer 81 detects the voltage of the DC power supply 90 based on the detection signal from the DC power supply voltage detection circuit 86c.

[0168] The microcomputer 82 controls the charging of the battery packs 29a and 29b in the cold box 1001. The microcomputer 82 controls the charging voltage by controlling the charging circuit 88. The charging circuit 88 is a charging unit that can charge the battery packs 29a and 29b using the power supplied from the external power supply (the power supplied from the DC power supply 90). The charging circuit 88 converts the input voltage from the DC power supply 90 into the charging voltage of the battery pack 29a or the battery pack 29b according to the control of the microcomputer 82, and supplies it to the battery pack 29a or the battery pack 29b (charges the battery pack 29a or the battery pack 29b).

[0169] The microcomputer 82 controls the on / off of the switch elements Q1 and Q2 provided between the output terminal of the charging circuit 88 and the charging terminal (C+ terminal) of the battery packs 29a and 29b, and determines which of the battery packs 29a and 29b is to be charged. Diodes D5 and D6 for backflow prevention are connected between the switch elements Q1 and Q2 and the microcomputer 82. The microcomputer 82 detects the voltage of the battery packs 29a and 29b based on the detection signal from the battery voltage detection circuits 86a and 86b. The microcomputer 82 detects the charging current based on the voltage of the shunt resistor 89 provided in the output current path of the charging circuit 88.

[0170] In addition to the charging control, the microcomputer 82 controls the on / off of the relays SW2 and SW3 as switches connected to the positive terminals (+ terminals) of the battery packs 29a and 29b to determine which of the battery packs 29a and 29b is to be discharged. The microcomputer 82 controls the on / off of the relay SW4 as a switch connected to the positive terminal (+ terminal) of the DC power supply 90 to determine whether to discharge from the DC power supply 90 to the cooling and heating function load unit 115.

[0171] Fuses F1 to F3 and backflow prevention diodes D1 to D3 are connected to the positive terminals of battery packs 29a, 29b and DC power supply 90. Microcomputer 82 controls the on / off of relay SW1 as a switch connected between the cathode of diode D3 and the cathodes of diodes D1 and D2.

[0172] The microcomputers 81 and 82 can communicate with each other and share various information. For example, the microcomputer 82 can obtain voltage information of the DC power source 90 by communicating with the microcomputer 81 .

[0173] This embodiment has the following effects.

[0174] (1) The hook portion 100 is provided at a position lower than the handle portion 21. Therefore, it is possible to prevent the situation where it is difficult to hook the hand on the handle portion 21 due to the object hooked on the hook portion 100. Therefore, even when the object is hooked on the hook portion 100, it is easy to hold the handle portion 21 and lift the cold box 1001, which is convenient to use.

[0175] (2) Since the protruding length of the hook portion 100 is less than the protruding length of the handle portion 21, the hook portion 100 can be prevented from becoming an obstacle when the hand is hooked on the handle portion 21, and the convenience of use is improved. In addition, by providing the hook portion 100, the width of the cold box 1001 in the left-right direction is prevented from increasing, and the cold box 1001 is prevented from being enlarged.

[0176] (3) The right hook portion 100 extends so as to protrude outward from the right side of the right outer box 13 and face the right side of the right outer box 13. Similarly, the left hook portion 100 extends so as to protrude outward from the left side of the left outer box 12 and face the left side of the left outer box 12. Fig.10 As shown, the seat belt 201 can pass between the hook portion 100 and the right side surface of the right outer box 13 (or the left side surface of the left outer box 12), the cold box 1001 can be stably placed on the seat of the vehicle, and the risk of the cold box 1001 rolling over due to cornering and braking can be suppressed. In addition, unlike the structure in which a recess is provided in the left outer box 12 or the right outer box 13 to pass the seat belt, the reduction in the volume of the storage chamber 8, the reduction in the cold or heat insulation performance caused by the reduction in the amount of the heat insulating material 17, and the reduction in the configuration space of the compressor 41 and the like can be suppressed.

[0177] (4) Fig. 9As shown, when the cold box 1001 is placed on the passenger seat 200 with the first hinge mechanism 25 and the second hinge mechanism 26 located on the side opposite to the driver's seat, the hook portion 100 on the right side faces the front side of the vehicle. And, when the seat belt 201 is hooked to the hook portion 100 on the right side and the cold box 1001 is held on the passenger seat 200, the handle portion 6a of the first cover 6 is located on the driver's seat side. Fig.11 As shown, it is easy to open the first cover 6 from the driver's seat. Fig. 9 As shown, the operation of closing the first cover 6 is also easy, and the items in the cold box 1001 are also easy to take out and put in, and the convenience of use is good. In addition, in the case of a vehicle with a passenger seat on the right side of the driver's seat, the cold box 1001 is placed on the passenger seat with the left hook portion 100 facing the front side of the vehicle, and the seat belt is hooked on the left hook portion 100 to hold the cold box 1001, thereby obtaining the same effect.

[0178] (5) As shown in Fig. 8(A) and Fig. 8(B), the left outer box 12 and the right outer box 13 have inclined portions 12b and 13b which expand outwards as they go upwards above the hook portion 100. Therefore, the seat belt hooked on the hook portion 100 is prevented from falling upwards, and the retention of the seat belt on the cold box 1001 is improved.

[0179] (6) The hook portion 100 extends in the center of the cold box 1001 or upward from the center in the vertical direction. Therefore, compared with the case where the hook portion 100 is located below the center of the cold box 1001, the seat belt 201 hooked on the hook portion 100 can improve the rollover prevention effect on the cold box 1001. In addition, compared with the case where the hook portion 100 is located below the center of the cold box 1001, Fig. 9 In this state, the area covered by the seat belt 201 of the air intake port 23 and the air exhaust port 24 located at the lower part of the front surface and the back surface of the right outer box 13 can be reduced, thereby suppressing the reduction in the efficiency of air intake and exhaust and suppressing the reduction in cooling or heat preservation performance.

[0180] (7) The hook portion 100 is open at the top and is configured to be able to hook the seat belt 201 from above. Fig. 9 The seat belt 201 in the state of applying tension to press the hook portion 100 downward, so that the seat belt 201 is unlikely to fall off from the hook portion 100.

[0181] (8) Since at least the middle portion of the second bridge portion 105 protrudes further outward than the first bridge portion 104, as shown in Figures 12(A) and 12(B), when an object is hooked on the second bridge portion 105, the first bridge portion 104 can be prevented from becoming an obstacle, thereby improving ease of use.

[0182] In the cold box 1001, the fastener 111 may also be embedded in the left outer box 12 or the right outer box 13. In addition, the hook portion 100 on the left side may be omitted. When the hook portion 100 on the left side is omitted, the recess 12a of the left outer box 12 is not required, and the amount of the heat insulating material 17 can be increased to improve the cold or heat insulation performance. The positional relationship between the first main body 3 and the second main body 4 in the left-right direction may also be reversed. The right chamber 8R and the left chamber 8L may also be the same size. The cold box 1001 may also be a one-chamber structure without the partition plate 70.

[0183] (Implementation Method 2)

[0184] Figure 15(A) is a three-dimensional view of the main parts of the cold box 1002 of the second embodiment. Figure 15(B) is a cross-sectional view of the main parts of the cold box 1002. The following description will focus on the differences from the first embodiment. The cold box 1002 is a structure in which the handle portion 21 and the hook portion 100 of the cold box 1001 are replaced with a handle-integrated hook 300 as an integral component (e.g., a resin molded body). The handle-integrated hook 300 has a handle portion 301 and a hook portion 302. A portion corresponding to the second bridge portion 105 of the hook portion 100 may also be provided in the hook portion 302. According to the present embodiment, since the handle portion 301 and the hook portion 302 are an integral component, the number of components is reduced and the assembly efficiency is improved.

[0185] (Implementation 3)

[0186] FIG16(A) is a perspective view of the main parts of the cold box 1003 of Embodiment 3. FIG16(B) is a cross-sectional view of the main parts of the cold box 1003. The following description will focus on the differences from Embodiment 1. The cold box 1003 uses the hook portion 100 on the right side of the cold box 1001 as a hook portion 400 that is integrated with the right outer box 13. The shape of the hook portion 400 is the same as the shape of the portion of the hook portion 100 that protrudes outward from the right outer box 13. Although omitted from the illustration, in the cold box 1003, the hook portion on the left side is also integrated with the left outer box 12 like the hook portion 400 on the right side. According to the present embodiment, the hook portion 400 is formed integrally when the left outer box 12 and the right outer box 13 are formed, so there is no need for a process for fixing the hook portion 400, and the assemblability is improved.

[0187] (Implementation 4)

[0188] Fig.17This is a stereoscopic view of a state where a cold box 1004 of Embodiment 4 is placed on a rear seat 202 and is held by a seat belt 203. The rear seat 202 is an example of a seat other than a driver's seat. The following description will focus on the differences from Embodiment 1. Cold box 1004 has a locking portion 150 (hook portion) added to the front surface of the left outer box 12 of cold box 1001. The locking portion 150 is set at the same height as the hook portion 100. The upper side of the locking portion 150 is open. As shown in FIG. Fig.17 As shown, when the cold box 1004 is placed on the rear seat 202 with the handle portion 6a of the first cover body 6 facing the front side of the vehicle, the cold box 1004 can be stably held on the rear seat 202 by hooking the seat belt 203 to the hook portion 100 and the locking portion 150. At this time, by positioning the hook portion 100 and the locking portion 150 above the air intake port 23, the seat belt 203 can be prevented from covering the air intake port 23, thereby suppressing a decrease in the efficiency of air intake and exhaust, and suppressing a decrease in the cold or heat insulation performance. The locking portion 150 is positioned above the air intake port 23. Fig.11 When the cold box 1004 is placed in the posture shown, it can also be used to hook the seat belt, so that the seat belt does not cover the air intake port 23. Although omitted from the figure, a locking portion similar to the locking portion 150 can also be provided on the back of the left outer box 12.

[0189] (Implementation modes 5 to 7)

[0190] Fig.18 The cold box 1005 of the fifth embodiment shown in the figure has the hook portion 100 of the cold box 1001 provided on the cold box of Patent Document 1. The cold box 1006 of the sixth embodiment shown in FIG. 19(A) has the handle-integrated hook 300 of the cold box 1002 provided on the cold box of Patent Document 1. The cold box 1007 of the seventh embodiment shown in FIG. 19(B) has the hook portion 400 of the cold box 1003 provided on the cold box of Patent Document 1. Providing the hook portion 100, the handle-integrated hook 300 or the hook portion 400 is also effective for improving the cold box of Patent Document 1.

[0191] (Example 8)

[0192] Figure 20 to Figure 27 This embodiment relates to Embodiment 8. In this embodiment, the structure of the rotating handle 14 of the cold box 1001, whose detailed description is omitted in Embodiment 1, is mainly described. Hereinafter, the drawings of Embodiment 1 are referred to as needed.

[0193] The handle 21 preferably has a width (length in the front-to-back direction) for hooking more than four adult fingers. As shown in FIG8(A), FIG8(B) and FIG23(A), FIG23(B), the handle 21 has a recess 21a on the lower surface. It is preferred that the width (length in the front-to-back direction) of the recess 21a is set to be greater than the width for hooking more than four adult fingers. The recess 21a may also replace the through hole.

[0194] The rotating handle 14 is connected to the left side of the main body 2 (the left side of the left outer box 12 and the main frame 11) and the opposite side (the right side of the right outer box 13 and the main frame 11), and can rotate relative to the main body 2 (can rotate relative to the shell of the cold box 1001). The handle portion 21 is located below the rotating handle 14. Fig.25 As shown, in the front-rear direction, a connection portion 151 to be described later and connected to the rotating handle 14 is located within the existence range of the handle portion 21 , and the handle portion 21 is located below (directly below) the connection portion 151 .

[0195] like Fig. 20 As shown, the rotatable range of the rotating handle 14 is limited by the handle portion 21. That is, the rotating handle 14 limits (determines) the rotation position when tilting forward and backward by contacting (engaging) with the upper portion of the handle portion 21. The upper portion of the handle portion 21 that contacts the rotating handle 14 corresponds to the limiting portion. Fig. 20 The rotatable range of the rotating handle 14 indicated by θ is more than 180°.

[0196] like Fig.21 As shown, when the rotating handle 14 is tilted forward, the USB terminal 27 can be visually recognized from the front, and the plug can be inserted and removed from the USB terminal 27. In addition, in the example shown in the figure, as the USB terminal 27, one type A and one type C are shown, but the type of USB terminal 27 can also be only one, and the number of USB terminals 27 is not limited in any way.

[0197] exist Fig.21 In the state, when viewed from the front, the handle portion 6a of the first cover body 6 is partially covered by the rotating handle 14, but the hand can be hooked on the handle portion 6a from the lower side of the rotating handle 14 to rotate the handle portion 6a forward, so that the first cover body 6 can be opened and closed. Fig.11 It can be seen that the first cover body 6 can be opened and closed even in a state where the rotary handle 14 is laid down rearward.

[0198] from Fig.21As can be seen from FIG. 23(A) and FIG. 23(B), the handle portion 21 on the left side extends to a position farther to the left than the rotating handle 14 from the left side surface of the shell of the cold box 1001 (a position farther to the left than the rotating handle 14). That is, the left end position of the handle portion 21 on the left side is located to the left of the left end position of the rotating handle 14. Similarly, the handle portion 21 on the right side extends to a position farther to the right than the rotating handle 14 from the right side surface of the shell of the cold box 1001 (a position farther to the right than the rotating handle 14). That is, the right end position of the handle portion 21 on the right side is located to the right of the right end position of the rotating handle 14.

[0199] like Fig.24 , Fig.25 As shown in FIG. 1 , the main frame 11 has a connection portion 151 connected to the rotating handle 14. The connection portion 151 is respectively provided at the center of the left and right sides of the main frame 11. The connection portion 151 is circular when viewed from the left and right directions. Fig.26 , Fig. 27 As shown in the figure, the left outer box 12 has a cutout portion 12c for avoiding the lower half of the connecting portion 151. Below the cutout portion 12c, there is a recessed portion 12d for inserting the handle portion 21, and below the recessed portion 12d, there is a recessed portion 12a for inserting the hook portion 100. The recessed portion 12d is provided with a through hole 152 for screwing the handle portion 21, and the recessed portion 12d is provided with a through hole 149 for screwing the hook portion 100. Although not shown in the figure, the right outer box 13 is also provided with a similar cutout portion, recessed portion, and through hole.

[0200] The connection part 151 has a through hole 147 in a two-stage shape at the center. As shown in Fig. 23 (A) and Fig. 23 (B), the rotary handle 14 is connected to the connection part 151 by a screw 141 passing through the through hole 147. The following is a specific description.

[0201] As shown in FIG. 23(A), a bracket 144 made of, for example, aluminum and having a threaded hole communicating with the through hole 147 is fixed to the left portion of the main frame 11 by screw fastening or the like. As shown in FIG. 23(B), a bracket 145 made of, for example, aluminum and having a threaded hole communicating with the through hole 147 is fixed to a frame 146 at the right portion of the main frame 11 by screw fastening or the like. The frame 146 is made of, for example, aluminum and is provided on the right outer box 13 in order to ensure the strength of the housing. The cylindrical protrusion 148 of the rotary handle 14 is rotatably fitted into the large diameter portion of the through hole 147.

[0202] As shown in FIG23(A), the screw 141 supporting the left portion of the rotating handle 14 passes through the root portion of the left side of the rotating handle 14 and the through hole 147 of the main frame 11, and is screwed into the threaded hole of the bracket 144. Similarly, as shown in FIG23(B), the screw 141 supporting the right portion of the rotating handle 14 passes through the root portion of the right side of the rotating handle 14 and the through hole 147 of the main frame 11, and is screwed into the threaded hole of the bracket 145.

[0203] A spacer 142 made of aluminum, for example, is sandwiched between the outer peripheral surface of the screw 141 and the rotating handle 14. An elastic ring 143 (rubber damper) is provided around the through hole 147. By providing the spacer 142, the elastic ring 143 is clamped by the rotating handle 14 and the main frame 11 and appropriately compressed when the screw 141 is tightened. Thus, an appropriate sliding resistance is applied to the rotation of the rotating handle 14 relative to the main frame 11.

[0204] This embodiment has the following effects.

[0205] (1) The cold box 1001 has a rotating handle 14 suitable for carrying with one hand and a pair of handles 21 suitable for carrying with both hands. Therefore, the user can choose whether to carry the cold box 1001 with one hand by holding the rotating handle 14 or with both hands by holding the pair of handles 21, for example, according to the total weight of the cold box 1001 corresponding to the contents, and the convenience of carrying is high. That is, the ease of carrying required for a portable cold box that can be used outdoors can be greatly improved.

[0206] (2) The handle 21 is located below the rotating handle 14 and its connecting portion 151. The handle 21 is used by hooking fingers on the lower part of the handle 21 to lift the cold box 1001. Therefore, by positioning the rotating handle 14 above the handle 21, the rotating handle 14 can be prevented from becoming an obstacle when the cold box 1001 is lifted by holding the handle 21, regardless of the rotation position of the rotating handle 14.

[0207] (3) The grip 21 extends to a position that protrudes in the left-right direction from the root of the rotating knob 14. Therefore, compared with a case where the root of the rotating knob 14 protrudes in the left-right direction from the grip 21, the root of the rotating knob 14 can be prevented from becoming an obstacle when the grip 21 is gripped.

[0208] (4) When the rotating handle 14 is laid down, the gap between the rotating handle 14 and the main body 2 in the front-to-back direction is small, so even if the rotating handle 14 is present between the body of the user carrying the cold box 1001 and the main body 2, deterioration of portability can be suppressed.

[0209] (5) The upper portion of the handle portion 21 functions as a limiting portion to limit the rotatable range of the rotating handle 14. Therefore, compared with the case where the limiting portion that limits the rotatable range of the rotating handle 14 is provided on the rotating shaft of the rotating handle 14, the strength of the limiting portion can be increased to improve the reliability of the structure, and the heat insulating material 17 ( Figure 7 In addition, due to the rotation range of the rotating handle 14 limited by the handle portion 21, that is, Fig. 20 The rotatable range of the rotating handle 14 indicated by θ is 180° or more, so that the rotating handle 14 can be prevented from becoming an obstacle when the rotating handle 14 is laid down.

[0210] (6) Fig.21 As shown, when the rotating handle 14 is tilted forward, the USB terminal 27 can be visually recognized from the front, and the plug can be inserted and removed from the USB terminal 27. Therefore, the USB terminal 27 can be used even when the rotating handle 14 is tilted forward, and the convenience of use is good.

[0211] (7) Even when the rotary handle 14 is tilted forward, the first cover 6 can be opened and closed, and the contents of the cold box 1001 can be taken in and out, so the usability is good.

The front and back of the left outer box 12 are the sides of the shell of the cold box 1001, corresponding to the connection part 151 ( Fig.24 ) on different sides. Fig.30 As shown, the handle portion 121 limits the rotatable range of the rotary handle 14 . Fig.30 The rotatable range of the rotating handle 14 shown in θ is Fig. 20 The rotatable range of the rotating handle 14 shown in θ is the same.

[0214] In this embodiment, since the distance between the body of the user holding the handle portion 121 and the handle portion 121 is longer than the distance between the body of the user holding the handle portion 21 of the cold box 1001 of embodiments 1 and 8, the user tends to feel heavy. On the other hand, since the distance between the pair of handle portions 121 is shorter than the distance between the pair of handle portions 21, the user only needs to open his hands to a smaller extent, and it can be said that it is easy to hold in this regard. Other aspects of this embodiment are the same as those of embodiments 1 and 8, and have the same effects.
