[0004] [Patent Literature]

[0005] Patent Literature 1: Japanese Patent Application Laid-Open No. 2019-80532 SUMMARY

[0006] [Problems to be Solved by the Invention]

[0007] As shown also as a technical problem in Patent Literature 1, in a state where the lid is open, when a force (overload) in a direction to further open the lid is applied to the lid by mistake, the lid itself and the hinge portion can be damaged. In view of this problem, in the invention described in Patent Literature 1, a stopper that limits the rotation of the lid beyond the open state of the lid is provided on the box main body.

[0008] However, if the user can be made to notice that the lid is being subjected to an external force that causes it to further open from a prescribed open position, the user can be made to take action to remove the external force before the lid is damaged. In addition, in the invention described in Patent Literature 1, although the lid can be prevented from being opened to such an extent that the parts are damaged, it is not considered from the perspective of making the user notice that the external force is being applied to the lid.

[0009] Therefore, the technical problem to be solved by the present application is to provide a cooler box that can make the user notice that the lid is being subjected to an external force that causes it to further open from a prescribed open position.

[0010] [Technical Solution for Solving the Problem]

[0011] A cold storage box according to an embodiment of the present application includes a main body portion having an opening portion and capable of storing an object to be stored in an interior, and a lid portion capable of opening and closing the opening portion by rotating with respect to the main body portion. The lid portion includes a lid main body and a cover portion. The cover portion is formed separately from the lid main body and is connected to the lid main body. The cover portion has a part of a hinge mechanism for rotating the lid portion with respect to the main body portion. A clamping body is clamped between the lid main body and the cover portion. The clamping body is formed separately from the lid main body and the cover portion. When the lid portion is subjected to an external force to further open from a predetermined open position, the clamping body is displaced in position with respect to at least one of the lid main body and the cover portion.

[0012] According to this structure, a sound is emitted by the clamping body being displaced in position, or the clamping body is detached from the lid main body and the cover portion, so that an abnormality can be informed to a user.

[0013] Further, one of the lid main body and the cover portion can have an end surface facing the other, and the clamping body can have an engaging portion positioned with respect to the one by engaging with the engaging surface.

[0014] According to this structure, when the clamping body is clamped between the lid main body and the cover portion, the clamping state of the clamping body is stabilized because the engaging portion engages with the engaging surface.

[0015] Further, the clamping body can have a slope that, when the lid main body moves with respect to the cover portion in a state where the lid portion is subjected to an external force to further open from the predetermined open position, abuts against a part of the lid main body to convert a part of the moving force into a force to suppress rotation of the clamping body with the displacement in position.

[0016] According to this structure, the clamping body can be suppressed from being detached from the position clamped between the lid main body and the cover portion in a short time.

[0017] [Effects of Invention]

[0018] According to the present application, a sound is emitted by the clamping body being displaced in position, or the clamping body is detached from the lid main body and the cover portion, so that an abnormality can be informed to a user. Therefore, the user can be made to pay attention to the fact that the lid is in an overloaded state. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0027] Next, the present application will be described by citing one embodiment. In the present embodiment, a refrigerating case 1 in a state in which a lid portion 3 is in an open state is shown in FIG. 1. Figure 1

[0028] As with the structure of the prior art, the refrigerating case 1 of the present embodiment has a main body portion 2 having an opening portion 21 that is open upward and is capable of housing an object to be housed inside, and a lid portion 3 that opens and closes the opening portion 21 by moving with respect to the main body portion 2. In addition, although not all are illustrated, a locking device for maintaining the lid portion 3 in a closed state is provided across the range of the main body portion 2 and the lid portion 3. The refrigerating case 1 is generally rectangular in plan view. The lid portion 3 of the present embodiment is set to "double opening", and the movement of the lid portion 3 with respect to the main body portion 2 can be, for example, movement in which one of the two parallel long sides in the shape in plan view (the upper right long side or the lower left long side shown in FIG. 1) functions as a hinge, and the lid portion 3 is lifted up and turned on the other long side side. Figure 1 By this movement, the lid portion 3 can be in a closed state and an open state. ​

[0029] The main body 2 has Figure 2 The fixed shaft 22 is fixedly provided to the main body 2. In the present embodiment, as shown in Figure 1 The fixed shaft 22 is provided along both long sides of the opening 21 of the main body 2, respectively. On each long side, two of the fixed shafts 22 are provided at positions symmetrically located with respect to the center in the length direction.

[0030] The lid portion 3 has a lid main body 31 and a cover portion 32, wherein the lid main body 31 occupies most of the lid portion 3, and the cover portion 32 is formed separately from the lid main body 31 and is connected to both end portions of the lid main body 31 in the width direction. The connection of the two is achieved by fitting and screw fastening. However, the connection method of the two is not particularly limited, and can also be fitting (alone), screw fastening (alone), adhesion, or fitting of a fitting member. The lid portion 3 has an operation handle and a locking member 33 (refer to Figure 2 ) that are not shown, wherein the operation handle is used for the user to operate, and the locking member 33 is engaged with the fixed shaft 22 in a manner linked with the operation of the operation handle. The locking member 33 has a claw portion 331 at the top end, which is engaged with the fixed shaft 22. The locking member 33, by cooperating with the fixed shaft 22, keeps the lid portion 3 in a closed state. That is, the locking member 33 and the fixed shaft 22 are part of the locking device. In addition, the cover portion 32 is provided in a manner covering the locking device. In addition, the fixed shaft 22 and the locking member 33 in the engaged state also function as a hinge mechanism for the lid portion 3 to rotate with respect to the main body 2. Figure 1 The portion at which the main body 2 and the lid portion 3 are connected is the portion that functions as a hinge mechanism. The locking member 33 is provided to the cover portion 32. That is, the cover portion 32 has part of the hinge mechanism for the lid portion 3 to rotate with respect to the main body.

[0031] Since the lid main body 31 and the cover portion 32 are not formed integrally except for the connection portion, when the lid main body 31 is subjected to an external force, the lid main body 31 and the cover portion 32 exhibit different behaviors. Specifically, in the case where a force in the direction of opening the lid portion 3 (in the description of the present embodiment, such a force is referred to as "overload") is further applied to the lid portion 3 from the open state, i.e., a state in which the lid portion 3 is normally fully open and is in a prescribed open position, since the lid main body 31 and the cover portion 32 are formed separately and are not integrated except for the connection portion, the rotation angle of the lid main body 31, which is relatively far from the hinge mechanism, with respect to the main body 2 is greater than the rotation angle of the cover portion 32, which is relatively close to the hinge mechanism. That is, the lid main body 31 and the cover portion 32, which are arranged in a straight line, change to an arrangement in a substantially V shape. Therefore, the gap between the lid main body 31 and the cover portion 32 becomes large in the case where the lid is subjected to an overload.

[0032] A clamping body 4 is sandwiched between the cover body 31 and the cover portion 32. The clamping body 4 is formed separately from both the cover body 31 and the cover portion 32. For example, the clamping body 4 is formed as follows: Figure 3 The shape shown. In the refrigerator 1 of this embodiment, two clamping bodies 4 are installed on each long side of the main body 2. The two clamping bodies 4 are respectively designed to be symmetrical (mirror symmetrical). The clamping bodies 4 are made of resin (in this embodiment, POM resin) and are solid (however, they may also be hollow). The clamping body 4 mainly has a main body 41, a locking part 42, and a slope 43.

[0033] The main body 41 is a columnar portion, and when disposed on the cover 3, its length direction corresponds to the thickness direction of the cover 3. The engaging portion 42 is a deformed tetrahedral pyramidal protrusion extending to the side of the main body 41. In this embodiment, Figure 3 The upper surface (the surface on the inner side of the cover 3) shown is a plane, and the lower surface is a slope. This upper surface, as... Figure 5 When disposed in the cover portion 3 as shown, it abuts against the inner surface of the recess 3211 in the cover portion 32. The inclined surface 43 is a surface formed on the side of the main body 41, and is a surface different from the surface of the main body 41 where the engaging portion 42 is formed (in this embodiment, it is an adjacent surface). The inclined surface 43 is as shown... Figure 5 When arranged in the cover 3 as shown, the surface is inclined in the inward and outward directions (vertical direction in the figure) relative to the top view of the cover 3. In this embodiment, it is set as a plane (however, it may also be a curved surface).

[0034] The clamping body 4 is positioned at a predetermined clamping position A, which is a position where a gap exists between the cover body 31 and the cover portion 32. In this embodiment, the clamping body 4 is moved from... Figure 2 Insert from the left to the right. Additionally, in Figure 4 The cover 3 is shown upside down, with its planar side (located on the outer surface of the refrigerator 1) and bottom side (located on the inner surface of the refrigerator 1). The clamping body 4 is then inserted from this... Figure 4 The top of the middle is downward (refer to) Figure 4 Insert the arrow. Through this insertion, the clamping body 4 is positioned at the designated clamping position A (however, in...). Figure 4 (The main body portion of the cover 32 connected to the cover body 31 is omitted in the illustration.) Furthermore, the clamping body 4 can be configured in a predetermined clamping position A before or simultaneously with the assembly of the cover body 31 and the cover 32, and the configuration method of the clamping body 4 is not limited to insertion.

[0035] exist Figure 5The positional relationship of the cover body 31, the cover portion 32, and the mounting body 4 when viewed in a lateral cross section in a state where the mounting body 4 is disposed in the prescribed mounting position A is shown in FIG. 6. Here, the end surface of the cover portion 32 facing the cover body 31 becomes the engagement surface 321. Also, in correspondence therewith, the mounting body 4 has an engagement portion 42 that is positioned with respect to the cover body 31 by engaging with the engagement surface 321 of the cover portion 32.

[0036] A recessed portion 3211 that opens toward the cover body 31 is formed on the engagement surface 321. This recessed portion 3211 is a portion divided by the rib portion on the engagement surface 321. The engagement portion 42 of the mounting body 4 is a protrusion that protrudes from the body 41. As shown in FIG. 6, the engagement portion 42 of the mounting body 4 disposed in the prescribed mounting position A enters the recessed portion 3211 of the engagement surface 321. Therefore, when the mounting body 4 is mounted between the cover body 31 and the cover portion 32, the mounting state of the mounting body 4 is stabilized because the engagement portion 42 engages with the engagement surface 321. Figure 5

[0037] When the cover portion 3 receives an external force that causes it to open further from the prescribed open position, the mounting body 4 is displaced in position with respect to at least one of the cover body 31 and the cover portion 32 from the prescribed mounting position A. With respect to this displacement in position, the following is described.

[0038] By the cover body 31 moving with respect to the cover portion 32, the gap between the cover portion 32 and the cover body 31 gradually increases at the prescribed mounting position A. Along with this, the mounting body 4 rotates about the axis. The direction of rotation at the prescribed mounting position A is the counterclockwise direction shown in the drawing. When this rotation continues, the engagement portion 42 of the mounting body 4 disengages from the recessed portion 3211 of the cover portion 32, and thus the mounting body 4 disengages from the prescribed mounting position A. Figure 5

[0039] In this way, by the mounting body 4 being displaced in position, first a sound is emitted (audible notification). Next, the mounting body 4 disengages from the cover body 31 and the cover portion 32 (visual notification). In this way, the user is notified of an abnormality (for example, that the cover portion 3 is in an overloaded state). In particular, in the present embodiment, because two stages of notification are achieved, the user's awareness of the abnormality is doubled. Also, a tactile notification that is achieved by transmitting a vibration and the like accompanying the displacement in position of the mounting body 4 to the user can be performed together with the audible notification and the visual notification. With respect to this tactile notification, for example, the case where the load on the mounting body 4 rises as a result of the mounting body 4 being displaced in position by the load when the user presses the cover portion 3 before the cover body 31 is deformed greatly with respect to the cover portion 32 can be cited as a resistance feeling that is felt by the user's hand.

[0040] ​​The inclined surface 43 of the clamping body 4 in this embodiment suppresses the rotation of the clamping body 4 itself when the position is offset. When the cover 3 is being subjected to an external force that causes it to open further from a predetermined open position, the cover body 31 moves relative to the cover 32 ( Figure 5 When the direction of arrow 31M is indicated, the inclined surface 43 abuts against the rib 311, which is part of the cover body 31. The rib 311 is a plate-shaped portion formed extending along the thickness direction of the cover 3. Here, without the rib 311, the cover body 31 is moved relative to the cover 32 as described above, that is, the clamping body 4 is rotated. By this rotation, the engaging portion 42 of the clamping body 4 disengages from the recess 3211 of the cover 32, thereby causing the clamping body 4 to disengage from the predetermined clamping position A in a short time after the cover body 31 begins to move.

[0041] On the other hand, with the rib 311 present, the contact point 311P, which is a corner portion of the rib 311, abuts against the inclined surface 43. A portion of the force causing the cover body 31 to move relative to the cover portion 32 is converted into a force originating from the contact point 311P, which suppresses the rotation of the clamping body 4 as the position shifts. Thus, by having the inclined surface 43, the clamping body 4's engaging portion 42 can be delayed from disengaging from the recess 3211 of the cover portion 32, holding the clamping body 4 in the predetermined clamping position A for a certain period, thereby suppressing disengagement from that position in a shorter time.

[0042] That is, when the cover body 31 is in an overloaded state in the opening direction, the cover body 31 moves in the separation direction relative to the cover portion 32. Figure 5 The lower part of the cover body 31 moves. When the cover body 31 moves, the rib 311, which is part of the cover body 31, also moves. Although the clamping body 4 is pushed by the abutment point 311P of the moving rib 311, the engaging part 42 of the clamping body 4 abuts against the inner surface of the recess 3211, so the clamping body 4 will remain at the predetermined clamping position A before the cover body 31 moves to a certain extent. When the clamping body 4 continues to be pushed by the rib 311, the clamping body 4 finally begins to rotate and eventually disengages from the predetermined clamping position A. In addition, the time for the clamping body 4 to remain at the predetermined clamping position A can be adjusted by setting the angle of the inclined surface 43 relative to the body 41 or the distance between the inclined surface 43 and the rib 311.

[0043] Additionally, by providing ribs 311 to the cover body 31, such as Figure 5 As shown, the gap between the cover body 31 and the cover portion 32 is filled by the clamping body 4. Therefore, the separately formed cover body 31 and cover portion 32 are integrated by the clamping body 4, which serves as a so-called "filler".

[0044] The clip 4 can be reused, even if it is detached from the lid body 31 and the cover portion 32, by a user reinserting it into the prescribed clip position A, and it can function again. Also, in the cooler 1 of the present embodiment, the space of the prescribed clip position A is a space formed before the clip 4 is introduced. Therefore, even if the clip 4 is not inserted, the cooler 1 itself can be used.

[0045] With the cooler 1 of the present embodiment, by the clip 4 being offset at the prescribed clip position A, the user can be informed of the abnormality by auditory notification, visual notification, tactile notification, or a combination thereof. Therefore, the user can be made aware that the lid is in an overloaded state, and the user can be prompted to take action. Therefore, the occurrence of cracks or other damage to the lid portion 3 can be prevented.

[0046] The above describes one embodiment of the present application, but the present application is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present application.

[0047] For example, although the lid portion 3 of the above-described embodiment is "double-hinged", it can also be "single-hinged" in which one of the two parallel long sides in the shape when viewed from above is provided with a hinge that cannot be separated from the body portion 2.

[0048] Also, the locking device of the above-described embodiment has the fixed shaft 22 provided to the body portion 2 and the locking member 33 provided to the lid portion 3, but it can also be reversed, with the body portion 2 having the locking member and the lid portion 3 having the fixed shaft.

[0049] Also, in the above-described embodiment, the hinge mechanism is constituted by the locking member 33 having the claw portion 331 and the fixed shaft 22. However, the shapes of the parts of the hinge mechanism are not limited to those of the above-described embodiment, and various modifications can be made.

[0050] Also, in the above-described embodiment, the end surface of the cover portion 32 that faces the lid body 31 is provided as the engagement surface 321. However, the engagement surface 321 is not limited to this, and it is sufficient that the end surface of one of the lid body 31 and the cover portion 32 that faces the other is provided as the engagement surface 321.

[0051] Also, in the above-described embodiment, the recess 3211 is formed in the engagement surface 321 of the cover portion 32, and the engagement portion of the clip 4 is a protrusion that engages with the recess. However, the cover portion 32 and the clip 4 can be engaged in various ways. Also, in the case of a concave-convex engagement, the concave-convex relationship of the engagement surface 321 and the clip 4 can be reversed from the above-described embodiment, or it can be an engagement in which steps abut, or the concave-convex shapes can be various shapes.

[0052] In addition, as Figure 6 (portion equivalent to the portion shown in Figure 4 As shown in FIG. 6 (portion equivalent to the portion shown in FIG. 5), a detachment preventing portion 44 can also be formed on the clamp body 4. This detachment preventing portion 44 is a portion having an L-shaped cross-sectional shape, which is configured in such a manner as to pass by the rib portion 311 formed on the cover body 31 in the above embodiment, and exist in the space on the opposite side of the clamp body 4 involved in the above embodiment. By forming the detachment preventing portion 44 like this, even if the clamp body 4 is displaced in position, the clamp body 4 will not be detached from the prescribed clamping position A. Therefore, there will be no case where the clamp body 4 is lost due to detachment of the clamp body 4 on a ship, for example, or on a shore.
