Detailed Description
Next, the present invention will be described by referring to an embodiment. Fig. 1 shows the shape of the refrigerator 1 according to the present embodiment. However, in fig. 1, the appearance of the main body 2 is shown only by a two-dot chain line. In the following description, the terms "up and down", "high and low", and "horizontal" correspond to the states shown in fig. 1 to 5. The "inner and outer sides" are defined as the inner side in the direction toward the center portion of the lid portion 3 in plan view shown in fig. 1 and the outer side in the direction toward the end edge of the lid portion 3 in plan view. In fig. 4 and 5, the right side is shown as the inside, and the left side is shown as the outside.
Basically, like the refrigerator of the related art, the refrigerator 1 of the present embodiment includes a main body 2 and a lid 3, wherein the main body 2 has an opening 21 that opens upward and is capable of storing and storing objects such as fish therein; the lid 3 moves relative to the body 2 to open and close the opening 21. As shown in fig. 3, a lock device L for holding the lid 3 in a closed state (a state not opened) is provided across the body 2 and the lid 3. As shown in fig. 3 to 5, the lock device L is constituted by a combination of the engaged portion 22 provided in the body 2, the operation lever 31 provided in the lid 3, the unlock holding portion 32, the regulating portion 33, and the lock mechanism portion 34. The refrigerator 1 has 2 sets of locking devices L, L, and two long sides of the main body 2 and the lid 3 are provided with one set. In fig. 3, a group of locking devices L, which are provided on the long side on the left side in fig. 1, are shown pulled out.
The main body 2 has a fixed shaft 22 (see fig. 3 to 5) as an engaged portion. The fixing shaft 22 is a part of a metal part shown in fig. 3, and the fixing shaft 22 is fixedly provided to the main body 2 by fixing the metal part to a wall surface of the main body 2 by means of screw fastening or the like. In the body 2 of the present embodiment, the fixed shafts 22 are provided along the two long sides of the opening 21 of the body 2 so that the axial centers thereof extend in the horizontal direction. For example, 2 fixed shafts 22 are provided on each long side of the main body 2 at positions symmetrical with respect to the center in the longitudinal direction. The fixed shaft 22 is disposed outside the opening 21. The fixed shaft 22 of the present embodiment is, for example, a straight rod having a circular cross-sectional shape.
The cover 3 includes a cover main body 3A, an operation lever 31, and a lock mechanism 34 (see fig. 3), wherein the cover main body 3A covers the opening 21; the operation handle 31 is an operation portion for the user to operate from the outside of the refrigerator 1; the lock mechanism 34 is linked with the operation handle 31. In relation to the cover body 3A, as shown in fig. 1 and 5, the state in which the operation lever 31 is laid down is the locked state, and as shown in fig. 2 and 4, the state in which a part of the operation lever 31 protrudes upward is the unlocked state.
The lid 3 of the present embodiment is formed so as to be opened in two directions, and the movement of the lid 3 with respect to the body 2 may be, for example, a movement in which the lid 3 is moved upward of the opening 21 in a substantially parallel state, and the entire lid 3 is separated from the body 2. The movement of the lid portion 3 with respect to the body portion 2 may be such that one of the operation levers 31 described later is set to a locked state and the other is set to an unlocked state, and a pair of locking devices L provided on one of two long sides parallel to each other in a shape in a plan view functions as a hinge, and the lid portion 3 is lifted up on the other long side to rotate the lid portion 3. By this movement, the lid 3 can be brought into the closed state and the open state.
As shown in fig. 1, the operation handle 31 is provided at the center in the longitudinal direction of the lid 3 having both ends of the long side. In addition, a part of the operation handle 31 is movable in the vertical direction. Specifically, as shown in fig. 1, 2, 4, and 5, the operation lever 31 is provided to the cover main body 3A such that an outer portion (the grip 312) moves in the vertical direction with respect to the cover main body 3A.
The operation handle 31 has a grip portion 312, and the grip portion 312 is a portion where a user inputs an external force for operating the operation handle 31 by hooking and gripping with a finger. The grip 312 is formed in a plate shape and extends outward, and a finger of the user is caught on a lower surface thereof. The grip 312 of the present embodiment is provided outside the operation handle 31 so that the user can insert a hand into the grip 312 from the outside to the inside. With such an arrangement, as compared with the case where the grip portion 312 is provided inside the operation handle 31, the space required for providing the operation handle 31 in the cover portion 3 can be reduced, and accordingly, the volume of the cover portion 3 in which the heat insulating material can be disposed can be increased. Further, since the operation handle 31 can be brought close to the outside of the lid portion 3, the step formed on the lid portion 3 can be reduced, and the discomfort given to the user when the user sits on the refrigerator case 1 can be reduced. The user can also operate the operation handle 31 from the side of the refrigerator 1.
When the grip portion 312 on the operation handle 31 is not operated by the user (intended operation by the user), the grip portion 312 is biased obliquely upward (elastically biased) with respect to the cover main body 3A by the elastic force of the biasing portion 323 (see fig. 4 and 5) as an extension spring. The operation handle 31 is held in the unlocked state by the biasing portion 323 biasing in the pulling direction. When the operation handle 31 is operated by the user (for example, when the user presses down the grip portion 312 of the operation handle 31 with a force of such a degree that the moving portion 322 gets over the step 331 of the regulating portion 33), the operation handle 31 is rotated about the rotation axis of the operation handle 31, that is, the axial center of the handle support shaft 311, with respect to the cover body 3A. The operation handle 31 and the lock mechanism 34 are physically connected as shown in fig. 3, and are integrally moved by the operation of the operation handle 31. Therefore, when the operation handle 31 is moved, the displacement is transmitted to the lock mechanism 34 via the operation handle support shaft 311, and the lock member 341 is interlocked (rotated).
The handle support shaft 311 is a straight rod-like member having a circular cross-sectional shape, and is provided so that the axial center extends in the horizontal direction along each of the two long sides of the cover 3 (the handle support shaft along one long side is shown in fig. 3). The handle support shaft 311 is rotatably supported to be interlocked with the lock mechanism portion 34. In the present embodiment, the handle support shaft 311 is rotatably supported by the rotating shaft 342. That is, as shown in fig. 4 and 5, the axial center of the handle support shaft 311 is not fixed in the lock device L, but rotates about the rotation shaft 342. However, the rotation is restricted by the moving portion 322 and the restricting portion 33. The operation lever support shaft 311 functions as an operation start point portion that receives an external force generated in association with the operation of the operation lever 31 by the user and serves as a start point of a force for operating the lock mechanism portion 34. This function will be described later.
As shown in fig. 3, an unlock holding portion 32 is connected to the operation handle 31. The unlock holding portion 32 includes a lever extension 321 and a moving portion 322. The lever extension 321 is a two-branched portion extending from both ends in the longitudinal direction of the lever 31 to the inside of the cover 3. The moving portion 322 is a straight rod having a circular cross-sectional shape, and both ends thereof are supported by the handle extensions 321, 321. The axis of the moving portion 322 is parallel to the axis of the lever support shaft 311.
The moving portion 322 moves to two positions, an unlocked position shown in fig. 4 and a locked position shown in fig. 5. The moving portion 322 can contact the restricting portion 33 provided on the inside and lower side of the operation handle 31 in the cover portion 3, and the moving portion 322 is prevented from shifting to an unintended lock position. Specifically, the moving portion 322 is separated from or brought into contact with the step 331 of the restricting portion 33 at the unlock position, and the moving portion 322 moves over the step 331 to the lock position. The moving portion 322 can approach or separate from the lever support shaft 311 within a predetermined range.
The unlocking holding portion 32 has a biasing portion 323, and the biasing portion 323 biases the moving portion 322 in the direction of the fixed projection 35, thereby holding the moving portion 322 at the unlocking position. The biasing portion 323 of the present embodiment has a helical tension spring. One end of the biasing portion 323 is attached to the moving portion 322, and the other end is attached to the fixed protrusion 35 formed on the cover portion 3. Further, by bringing the moving portion 322 into contact with the restricting portion 33, the moving portion 322 can be prevented from going over the step 331, and the moving portion 322 can be held at the unlock position.
As described above, the combination of the moving portion 322 and the regulating portion 33 allows the operation handle 31 and the lock mechanism portion 34 to be interlocked with each other (corresponding to a state in which the lock mechanism portion 34 is operable) and the operation handle 31 and the lock mechanism portion 34 to be not interlocked with each other (corresponding to a state in which the lock mechanism portion 34 is inoperable).
Here, a configuration for reducing the operation force of the operation handle 31 (the grip 312) in the refrigerator 1 of the present embodiment will be described. The operation lever support shaft 311 as an operation start portion is provided at a position outside the cover portion 3. The moving portion 322 is provided at a position inside the cover portion 3. The grip 312 is provided outside the cover 3 from the handle support shaft 311. As shown in fig. 5, a linear distance L312 from the grip portion 312 to the moving portion 322 (in terms of description, a position of the grip portion 312 to which the operation force is applied is set to a position of an arrow P3b shown in fig. 5) is set longer than a linear distance L311 from the handle support shaft 311 to the moving portion 322 in a vertical cross-sectional view. Since the distances of the respective portions are set in this manner, in the lever in which the handle support shaft 311 is pivoted with respect to the rotation shaft 342 with the moving portion 322 that moves inward beyond the step 331 of the regulating portion 33 and is placed on the regulating portion 33 as a fulcrum and the grip portion 312 that applies the operating force as a force receiving point, the force applied to the grip portion 312 for operating the lock mechanism portion 34 can be made smaller than in a case where the grip portion is provided at an inner position in the lid portion, the user inserts a hand into the grip portion from the inner side to the outer side, and the grip portion is provided so as to be close to the outer edge of the lid portion, for example, according to the principle of leverage.
With the restricting portion 33, the moving portion 322 is held at the unlock position by the moving portion 322 coming into contact therewith, and with the operation handle 31 operated, the restricting portion 33 allows the moving portion 322 to pass over the step 331, so that the moving portion 322 moves to the lock position.
The restriction portion 33 has a step 331. The step 331 has a shape shown in fig. 5, and the inside of the cover 3 is formed higher than the outside. The moving portion 322 located at the unlocking position is prevented from being accidentally shifted to the locking position by the contact of the moving portion 322 with the wall portion 3311 rising between the lower portion and the higher portion on the step 331. In this embodiment, at this time, the moving portion 322 is biased by the biasing portion 323 to maintain the state of the moving portion 322. The position (unlocked position, locked position) of the moving portion 322 is determined according to whether the moving portion 322 passes over the step 331. Therefore, in the refrigerator 1 of the present embodiment, the step 331, which is a partial shape of the restricting portion 33, prevents the movement of the moving portion 322 to the lock position and allows the movement of the moving portion 322 to the lock position. Therefore, the restricting portion 33 can be made to have a simple structure.
For example, as shown by an arrow P3a in fig. 4, an external force other than the operation of the operation handle 31 (an external force that is not related to the intention of the user and is caused by vibration, impact, or the like applied to the refrigerator 1) is applied downward to the operation handle 31 without any deviation between the inside and the outside. The moving portion 322 is biased by a biasing portion 323. However, the downward force does not move upward because the moving portion 322 contacts the step 331 only, and therefore does not move over the step 331. This is because the wall 3311 cannot pass over the step 331 if the moving portion 322 does not move upward. In this state, the movement of the moving portion 322 to the lock position is prevented, and therefore the handle support shaft 311 does not rotate with respect to the rotating shaft 342. Therefore, the lock mechanism portion 34 does not operate.
On the other hand, when the user operates the operation handle 31 (grip portion 312), an operation force as an external force is applied downward to the grip portion 312 located outside the operation handle 31 as shown by an arrow P3b in fig. 5, for example. This force is transmitted to the handle support shaft 311 serving as an operation start point portion, and the handle support shaft 311 rotates with respect to the rotation shaft 342. In parallel with this rotation, while the moving portion 322 passes over the step 331, a lever relationship is temporarily generated with the handle support shaft 311 as a fulcrum (however, the support shaft 311 as the fulcrum is not fixed but moves (rotates) with respect to the rotating shaft 342 as described above), the grasping portion 312 is a force receiving point, and the moving portion 322 is a point of action, and as a result, the moving portion 322 rises (counterclockwise arrow M322 relating to the movement of the moving portion 322 shown around the handle support shaft 311 in fig. 5). Moving portion 322 rises above step 331 with respect to wall 3311. During this raising, moving portion 322 may or may not contact wall 3311. When the moving portion 322 is raised, the wall portion 3311 is not positioned inside the moving portion 322, and therefore the moving portion 322 moves inward above the regulating portion 33. As shown in fig. 5, the tension spring serving as the biasing portion 323 is extended as the moving portion 322 moves inward. This is a state of passing over the step 331. Thus, since the rotation of the handle support shaft 311 with respect to the rotation shaft 342 cannot be prevented, the handle support shaft 311 moves within the movable range until it descends to the position shown in fig. 5, and the lock mechanism portion 34 is operated. At this time, the operation force reduction action based on the lever principle is as described above.
Thus, when the operation lever 31 is not operated from the outside, the lid 3 can be prevented from being held in the closed state (unable to be opened) against the user's intention. Accordingly, for example, since the lid 3 can be opened and closed by grasping any portion of the lid 3, operability when the refrigerator is used on a narrow fishing boat can be improved. In addition, when a user stores a large number of fish as stored objects in the refrigerator 1 in order, the user can easily store and store the fish by opening and closing the lid 3 without operating the operation handle 31.
The lock mechanism 34 is movable relative to the fixed shaft 22, and the cover 3 is held in the closed state by the moving portion 322 passing over the step 331 of the restricting portion 33 and engaging with the fixed shaft 22.
The lock mechanism 34 includes a lock member 341 as an engagement piece engaged with the fixed shaft 22. In the cover portion 3 of the present embodiment, the locking members 341 are provided along each of the two long sides on the cover portion 3. For example, two locking members 341 are provided on each long side of the cover 3 at positions symmetrical with respect to the center in the longitudinal direction. As shown in fig. 4 and 5, each locking member 341 is movable (rotatable) with respect to the fixed shaft 22 of the main body 2. Each locking member 341 has a claw 3411 as an engaging portion engaged with the fixed shaft 22. The claw portion 3411 faces one side of the rotation range with respect to the fixed shaft 22. The claw portion 3411 of the present embodiment faces the depth side (left side in fig. 4 and 5) with respect to the fixed shaft 22.
The two lock members 341, 341 of the lock mechanism portion 34 are connected by a connecting portion 343 to be integrated. The lock mechanism 34 is provided integrally with an L-shaped pivot branch 344, and the pivot branch 344 extends inward while rising upward from the connecting portion 343. The two rotational branches 344 are provided with the operation handle 31 therebetween. The handle support shaft 311 of the handle 31 is inserted through and fixed to the two pivot branches 344 and 344.
In addition, the lock member 341 rotates relative to the cover main body 3A. The rotation range of the locking member 341 is set to cover from the front side (see fig. 4) with respect to the fixed shaft 22 of the body 2 to a position where the claw 3411 is aligned with the fixed shaft 22 (see fig. 5). The claw portion 3411 may be set to reach the depth side beyond the fixed shaft 22. The lock member 341 extends downward with the lid portion 3 horizontal with respect to the rotation shaft 342 that is the rotation center of the lock member 341. The locking member 341 of the present embodiment is formed of a resin such as polyacetal (polyacetal) resin, or a material obtained by mixing glass into a resin.
The claw portions 3411 are movable relative to the fixed shaft 22, and engage with the fixed shaft 22 by an operation from the outside (for example, an operation (intended operation) of the operation lever 31 from the outside by a user), thereby holding the lid portion 3 in the closed state. The claw 3411 is movable between a locked state (see fig. 5) in which the claw is engaged with the fixed shaft 22 and an unlocked state (see fig. 4) in which the engagement (engagement with the fixed shaft 22) is released. The claw 3411 of the present embodiment is movable (clockwise in the figure) from the side close to the opening 21 toward the fixed shaft 22. The claw portion 3411 is held in an unlocked state when not being operated from the outside, and when the claw portion 3411 is operated from the outside with a force larger than the elastic force of the plate spring 345 to thereby apply a force to the plate spring 345, which can deform the plate spring 345, the claw portion 3411 moves from the unlocked state to a locked state.
The lock mechanism 34 includes a plate spring 345 as an elastic portion having an elastic force in cooperation with the claw portion 3411 of the lock member 341. The plate spring 345 is made of an elastic material such as metal or resin. Specifically, the plate spring 345 is made of stainless steel. The locking member 341 is provided with a through hole 346 penetrating in the inward and outward direction. The plate spring 345 is inserted through the through hole 346. Further, the formation of the through hole 346 is not necessary, and the plate spring 345 may not penetrate the locking part 341.
As described above, in the refrigerator 1 of the present embodiment, the restricting portion 33 prevents the moving portion 322 from moving to the lock position, and therefore, even if an external force other than the operation of the operation handle 31 is applied to the operation handle 31, the moving portion 322 is held at the unlock position by the restricting portion 33, and therefore, the lock mechanism portion 34 does not operate. Therefore, the usability of the locking device of the lid portion 3 of the refrigerator 1 can be improved.
While one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.
For example, the lid portion 3 of the above-described embodiment is "double-opened", but the lid portion 3 may be configured to be "single-opened" by providing a hinge (for example, a general circulating hinge) that is different from the one set of the locking devices L and cannot be separated from the main body portion 2, on one of two parallel long sides in a shape in plan view.
In the refrigerator 1 of the above embodiment, the fixed shaft 22 as the engaged portion provided on the main body 2 and the locking mechanism 34 provided on the lid 3 and engaged with the fixed shaft 22 are provided, but the main body 2 may have the locking mechanism and the lid 3 may have the engaged portion.
The operation portion of the above embodiment is the operation handle 31 in which the grip portion 312 is movable in the vertical direction, but may be a member movable in the horizontal direction or the vertical direction along a straight track. In this case, the member corresponding to the moving portion 322 may move in a linear path along with the movement of the operation handle 31. For example, a structure may be considered in which a sliding member corresponding to the operation handle 31 is slid in a horizontal direction or the like with respect to the cover body 3A, and thereby a force generated by the sliding is transmitted to the locking member 341 to move the locking member 341 from the unlocked state to the locked state, and a member corresponding to the regulating portion 33 is brought into contact with a member corresponding to the moving portion 322 to prevent the member corresponding to the moving portion 322 from moving to the unlocked position, and when the sliding member is operated, the member corresponding to the regulating portion 33 allows the member corresponding to the moving portion 322 to move to the locked position.
The lid 3 may be attached to the main body of the existing refrigerator instead of the lid of the existing refrigerator. In the refrigerator in which the replaced lid portion 3 is attached to the main body portion, as in the refrigerator 1 of the above-described embodiment, when the refrigerator is not operated from the outside, the engagement portion (the claw portion 3411) is always kept in a state where the engagement with the engaged portion (the fixed shaft 22) is released, and therefore, the lid portion 3 can be prevented from being kept in a closed state unexpectedly by the user. Therefore, the conventional refrigerator can be improved to a refrigerator which can be used more conveniently by replacing the lid of the conventional refrigerator with the lid 3.
