Description

  The present invention relates to a lid mechanism used for a double-open storage box that allows a lid to be opened and closed from one end side or the other end side.

  2. Description of the Related Art Conventionally, there is known a double-open type storage box that is disposed on a vehicle center console as a storage box for a vehicle and that opens and closes a lid by swinging from one end side or the other end side. As an example of such a double-opening type storage box, two lock mechanisms each having a hook lock pin are disposed at both ends on one end side and the other end side. In these two lock mechanisms, when the lid swings from one end side, the lock mechanism on one end side is unlocked, and the lock mechanism on the other end side is in a locked state to become a swing shaft. On the other hand, when the lid swings from the other end side, the lock mechanism on the other end side is unlocked, and the lock mechanism on the one end side is in the locked state to form the swing shaft.

  However, with only such two lock mechanisms, there is a possibility that when the lid is swinging, the lock mechanism serving as the swing shaft may be unlocked due to an erroneous operation by the operator. That is, there is a possibility that the two lock mechanisms may be unlocked at the same time, and the lid is detached from the box body. In order to solve such a problem, in the double-opening type storage box of Patent Document 1, the lid can be selectively swung from one end side or the other end side, and one lock mechanism is a rocking shaft. At the same time, a switching means that can maintain the lock state of the lock mechanism is disclosed.

  The double-opening type storage box disclosed in Patent Document 1 has two lock mechanisms and switching means. The switching means includes a connecting rod that connects the two lock mechanisms in a bridge shape, and a centering member that engages with the central portion of the connecting rod. The connecting rod is supported by the lid so as to be movable toward one end side or the other end side. When the connecting rod moves toward the one end side or the other end side, when the lid is swinging, one lock mechanism serving as the swing shaft maintains the locked state. The centering member is constituted by a cam mechanism having a coil spring. In the state where the lid is closed, the centering member returns the connecting rod moved toward one end side or the other end side to the neutral position by the biasing force of the coil spring. Thus, in a state where the lid is closed, the locked state of either one of the two lock mechanisms can be released again.

  As described above, the switching means disclosed in Patent Document 1 can selectively swing the lid from one end side or the other end side, and one lock mechanism serving as the swing shaft is in a locked state. The state change to the unlocked state is prevented. Therefore, according to the switching means disclosed in Patent Document 1, it is possible to solve the problem that the lid is detached from the box when the lid is swinging.

  However, in the switching means disclosed in Patent Document 1, a cam mechanism using a coil spring as a centering member is employed. For this reason, the structure is complicated and the assembly is troublesome.

  Accordingly, the present invention has been made in view of the above circumstances, and in a double-open type storage box having an erroneous operation preventing means for preventing the lid from coming off from the box body, an erroneous operation having a simple structure and easy assembly. Provided is a lid mechanism having prevention means.

  In order to solve the above-mentioned problems, the lid mechanism of the present invention has a base unit integrated with a box body having a storage part, and can swing from the other end side with respect to the base part from the other end side or centered on the other end side. A lid mechanism that can swing from one end side, and the lid has a lock mechanism that locks and unlocks the lid with respect to the base, and the lock mechanism has a first lock on one end side. And a second lock mechanism on the other end side. The first lock mechanism is configured to move the first rod, the first sub rod, and the first rod and the first sub rod toward or away from each other. A first synchronizing element that synchronizes the movement, and the second locking mechanism synchronizes the movement of the second rod, the second auxiliary rod, and the second rod and the second auxiliary rod toward or away from each other. A second synchronization element The first lock mechanism moves in a direction in which the first rod and the first sub rod move away from each other and engages the base, and moves in a direction in which the first rod and the first sub rod approach each other. The state changes between the first unlocking state in which the engagement with the base is released, and the second locking mechanism moves in the direction in which the second rod and the second sub rod are separated from each other and engages the base. The first lock release state is changed between the second lock state and the second lock release state in which the second rod and the second sub rod move toward each other and the engagement with the base is released. The lid swings around the second secondary rod, and when the second unlocked state, the lid swings around the first secondary rod, and the lock mechanism further includes the second lock mechanism. And synchronized with the state change of the second lock mechanism The first locking mechanism has a transmission rod that changes state with respect to the first locking mechanism, and in the first unlocking state, the first locking mechanism prevents the transmission rod from changing its state, and the second locking mechanism starts from the second locking state. The state change to the two lock release state is prevented, and the transmission rod prevents the state change from the first lock state to the first lock release state of the first lock mechanism in the second lock release state.

  In the lid mechanism of the present invention adopting the above-described configuration, a transmission rod is used instead of the cam mechanism that has been conventionally used as an erroneous operation preventing means. Therefore, the structure is simple and the assemblability is improved.

  The second assembly member 55 is juxtaposed on the right front end side of the arm portion 5, and rotatably supports the collar 72 that is inserted into the second arm through hole 52 and protrudes forward from the second arm through hole 52. The second assembly member 55 fixes the end of the second arm spring 71 that protrudes forward from the second arm through hole 52. Further, the second assembly member 55 holds the second damper 73 so as to mesh with the collar tooth row 72 a provided on the collar 72.

  The arm unit 53 unitized in this way is arranged so that the arm portion 5 is interposed between the rear base portion 32 and the lid main body portion 4 in the lid mechanism 1 of the embodiment. The first assembly member 54 in the arm unit 53 is assembled to the rear base 32, and the second assembly member 55 is assembled to the lid body 4.

  By assembling the arm unit 5 as a unit to form the arm unit 53 and assembling it to the lid mechanism 1, the assembly of the lid mechanism 1 of the embodiment is facilitated, and as a result, productivity is improved.

  Hereinafter, the operation of the lid mechanism 1 of the embodiment will be described. In the lid mechanism 1 of the embodiment, the lid 2 is configured to be openable and closable from both the right end side and the left end side. When the lid 2 opens and closes from the right end side, the lid main body 4 and the arm 5 swing together to change the state between the closed state and the first open state of the lid 2. At this time, the front end of the first sub rod 812 of the first lock mechanism 81 and the first support shaft 6 become the swing shaft of the lid 2. When the lid 2 opens and closes from the left end side, the arm portion 5 does not swing, but only the lid body portion 4 swings, and the state changes between the closed state and the second open state of the lid 2. At this time, the front end of the second secondary rod 822 of the second lock mechanism 82 and the second support shaft 7 serve as the swing shaft of the lid 2.

  With reference to FIG.2 and FIG.4, the state change from the closed state of the lid 2 to a 1st open state is demonstrated. 2 indicate the moving directions of the second switch 87, the second sub rod 822, the second rod 821, and the transmission rod 83. In FIG.

  First, the second lock state of the second lock mechanism 82 is changed to the second unlock state. That is, the operator presses the second switch 87 and moves the second switch 87 to the left. When the operator pushes the second switch 87 to the left, the groove wall of the notch 87a presses the convex portion 822a to the left. At this time, since the notch 87a is inclined from the left front toward the right rear, the convex portion 822a moves backward in the notch 87a. Accordingly, the second secondary rod 822 having the convex portion 822a also moves backward. Thus, the notch 87a provided in the second switch 87 converts the leftward force from the operator into the backward force and moves the second secondary rod 822 having the convex portion 822a rearward. Let

  When the second secondary rod 822 moves rearward, the second synchronization element 823 supporting the second secondary rod 822 rotates clockwise. At this time, the second rod 821 supported by the second synchronization element 823 moves forward because it is pulled forward by the second synchronization element 823. That is, when the operator presses the second switch 87, the second sub rod 822 and the second rod 821 move in a direction approaching each other due to the clockwise rotation of the second synchronization element 823. As a result, the front end of the second secondary rod 822 is detached from the front base 31, and the rear end of the second rod 821 is detached from the rear base 32. Therefore, the state of the second lock mechanism 82 changes from the second locked state to the second unlocked state. In the second locked state, the second secondary rod 822 receives a biasing force from the second biasing member 824 moving forward via the second synchronization element 823. Therefore, the operator presses the second switch 87 with a force against the urging force of the second urging member 824 in order to move the second sub rod 822 backward.

  When the second lock mechanism 82 is in the second unlocked state, the lid main body portion 4 and the arm portion 5 integrally swing in the opening direction according to the urging force of the first arm spring 61. At this time, since the first lock mechanism 81 is in the first locked state, the front end of the first sub rod 812 and the first support shaft 6 provided on the left end side become the swing shaft of the lid 2. Thus, the lid 2 changes its state from the closed state to the first open state according to the urging force of the first arm spring 61.

  When the lid 2 changes from the closed state to the first open state, the arm portion 5 and the lid main body portion 4 are connected and integrated on the left end side and the right end side, respectively. Specifically, since the first lock mechanism 81 is in the first locked state, the first rod 811 is engaged with the arm portion 5. Thus, the arm part 5 and the lid main body part 4 are connected to each other by the first rod 811 on the left end side. The front end portion of the collar 72 inserted through the second arm through hole 52 extends to the lid body portion 4 and is supported by the lid body portion 4. Further, since the second lock mechanism 82 is in the second unlocked state, the second rod rear end portion 821a of the second rod 821 is separated from the rear base portion 32, but is positioned in the second arm through hole 52. Yes. Thus, the arm part 5 and the lid main body part 4 are connected to each other by the collar 72 and the second rod rear end part 821a of the second rod 821 on the right end side. As described above, the arm portion 5 and the lid main body portion 4 are integrated with each other at the left end side and the right end side. Therefore, when the lid 2 changes from the closed state to the first open state, the arm portion 5 and the lid main body portion 4 swing integrally. In this case, since the arm part 5 is swinging, it does not remain on the box body 11 side. That is, since the arm portion 5 does not remain on the box body 11 side, it is possible to ensure a wide opening area of the storage portion 12. Moreover, since the arm part 5 does not remain on the box body 11 side, the appearance of the storage part 12 is improved.

  The lid mechanism 1 of the embodiment is provided with a transmission rod 83. When the operator presses the second switch 87, the second sub rod 822 and the second rod 821 move in a direction approaching each other. At this time, the second synchronization element 823 rotates clockwise, and the transmission rod 83 supported by the second synchronization element 823 is pulled by the second synchronization element 823 and moves rightward. When the transmission rod 83 moves to the right, the transmission rod contact portion 84a at the transmission rod distal end portion 84 faces the engagement convex portion 812c provided on the first sub rod 812. At this time, the transmission rod contact portion 84a is positioned on the front side on the movement locus of the engagement convex portion 812c.

  Since the transmission rod contact portion 84a is positioned on the front side of the movement locus of the engagement convex portion 812c, the backward movement of the first sub rod 812 is prevented. This is because, when the first sub rod 812 tries to move backward from the first locked state, the transmission rod abutting portion 84a in which the engaging convex portion 812c of the first sub rod 812 is located on the front side on the movement locus. It is for contacting. That is, the transmission rod contact portion 84a prevents the first sub rod 812 from moving rearward via the engagement convex portion 812c.

  When the backward movement of the first secondary rod 812 is prevented, the movement of the first rod 811 synchronized with the first secondary rod 812 is also prevented by the first synchronization element 813. Therefore, in the first open state, when the second unlocking state of the second lock mechanism 82 is maintained by the second restricting portion 9b of the restricting portion 9 as described later, the first lock state of the first lock mechanism 81 is maintained. Cannot be released. That is, the transmission rod 83 prevents the first lock mechanism 81 from changing from the first locked state to the first unlocked state. As a result, in the lid mechanism 1 of the embodiment, it is possible to prevent the front end of the first sub rod 812 serving as the swing shaft from being detached from the front base 31, and as a result, the lid 2 is detached from the base 3 and the box body 11 Can be prevented from coming off.

  In the lid mechanism 1 according to the embodiment, the restriction body 9 is provided in the lid body 4. By the way, as described above, when the operator presses the second switch 87, the second lock mechanism 82 changes from the second locked state to the second unlocked state. One lock mechanism 81 is prevented from changing from the first locked state to the first unlocked state. However, when the restricting portion 9 is not provided, when the operator releases the pressure on the second switch 87, the second unlocked state changes to the second locked state according to the biasing force of the second biasing member 824. Resulting in. Along with this, the transmission rod 83 returns to the original position, so that the blocking of the state change from the first locked state to the first unlocked state by the transmission rod 83 is released. Therefore, the first lock mechanism 81 that has been in the first locked state can be changed to the first unlocked state. In this case, since the first lock mechanism 81 and the second lock mechanism 82 can be simultaneously unlocked, the lid 2 may be detached from the base 3. Therefore, when the lid 2 is in the first open state by swinging with the front end of the first sub rod 812 and the first support shaft 6 as the swing shaft, the second lock mechanism 82 is moved from the second unlocked state to the second lock state. The 2nd control part 9b which blocks | prevents the state change to a state is arrange | positioned. In other words, when the lid 2 is in the first open state, the second restricting portion 9b maintains the second unlocked state. Hereinafter, the operation of the second restricting portion 9b will be described.

As for the 2nd control part 9b, the front-end part 91a and the rear-end part 91b of the control board 91 tilt in the shape of a seesaw. The restricting plate 91 is urged by the restricting plate urging portion 92 so that the front end portion 91a is directed downward in a state where it receives no force from other members. In the closed state of the lid 2, the front end portion 91 a of the restriction plate 91 is in contact with the front base portion 31 and is pushed up by the front base portion 31 against the urging force of the restriction plate urging portion 92. At this time, the restricting plate 91 is positioned such that the rear end portion 91b is lower than the front end portion 91a, and the rear end portion 91b of the restricting plate 91 is positioned below the rod protrusion 822b. That is, at this time, since the rear end portion 91b and the rod projection portion 822b are offset in the height direction, the rear end portion 91b and the rod projection portion 822b of the regulation plate 91 are engaged. Absent.

  When the lid 2 in the closed state changes to the first open state, the second secondary rod 822 of the second lock mechanism 82 moves rearward. Further, the second restricting portion 9 b located in front of the right end of the lid main body portion 4 changes its position together with the lid main body portion 4 and leaves the front base portion 31. When the second restricting portion 9b is separated from the front base portion 31, the restricting plate 91 of the second restricting portion 9b has the front end portion 91a facing downward and the rear end portion 91b facing upward according to the urging force of the restricting plate urging portion 92. Swing to face. As a result, the rear end portion 91b of the restriction plate 91 is positioned on the movement locus of the rod projection 822b of the second sub rod 822 that has moved rearward. Accordingly, the rod protrusion 822b is thereby engageable with the rear end 91b of the restriction plate 91.

  As described above, when changing the state of the lid 2 from the closed state to the first open state, the operator presses the second switch 87. The second switch 87 is urged by the second urging member 824 in a direction opposite to the pressing direction, that is, in a direction to return to the original position. The switch 87 returns to the original position. Further, when the operator releases the second switch 87, the second sub rod 822 and the second rod 821 that have moved in a direction approaching each other when the operator presses the second switch 87, While returning to the original position, the second secondary rod 822 and the second rod 821 also return to the original position. That is, the second sub rod 822 and the second rod 821 move in directions away from each other.

  Here, when the state of the lid 2 changes from the closed state to the first open state, the rear end portion 91b of the restriction plate 91 of the second restriction portion 9b changes in a position where it can engage with the rod protrusion 822b. That is, at this time, the movement of the second sub rod 822 in the forward direction is prevented by the engagement between the rear end portion 91b and the rod projection portion 822b. Therefore, the forward movement of the second auxiliary rod 822 and the backward movement of the second rod 821 in accordance with the urging force of the second urging member 824 are prevented. As a result, in the first open state of the lid 2, the second unlocking state of the second lock mechanism 82 is maintained by the second restricting portion 9b.

  In the lid mechanism 1 of the embodiment, a first damper 63 that reduces the rocking speed of the lid 2 is provided. Therefore, since the lid 2 can be gently swung, the lid mechanism 1 according to the embodiment can produce a high-class feeling.

  With reference to FIG.2 and FIG.4, the state change from the 1st open state of the lid 2 to a closed state is demonstrated. First, the operator presses the lid 2 in which the arm portion 5 and the lid main body portion 4 are integrated against the urging force of the first arm spring 61. Then, the lid 2 swings until the opening of the storage portion 12 is shielded from the passenger compartment. Finally, the lid 2 is changed from the first open state to the closed state, the restriction by the second restriction portion 9b described below is released, and the second lock mechanism 82 changes from the second lock release state to the second lock state. .

  When the state of the lid 2 changes from the first open state toward the closed state, the second restricting portion 9 b provided on the right front side of the lid main body portion 4 approaches the front base portion 31. In the first open state, the restricting plate 91 of the second restricting portion 9b is inclined with the restricting plate biasing portion 92 with the rear end portion 91b facing upward and the front end portion 91a facing downward. The rear end portion 91 b of the restriction plate 91 is engaged with the rod protrusion 822 b, and the front end portion 91 a of the restriction plate 91 protrudes forward from the lid main body portion 4. In other words, at this time, the second restricting portion 9b maintains the second unlocked state of the second lock mechanism 82, and as a result, the transmission rod 83 moves from the first locked state of the first lock mechanism 81 to the first lock state. The state change to the release state is prevented.

When the lid 2 in such a state swings to a predetermined position toward the closed state, the front end portion 91a of the restricting plate 91 of the second restricting portion 9b comes into contact with the front base portion 31. Thereafter, as the lid 2 swings toward the closed state, the front end portion 91 a is gradually pushed up to the front base portion 31. On the other hand, the rear end portion 91b that has been lifted according to the urging force of the restricting plate urging portion 92 is pushed down against the urging force of the restricting plate urging portion 92 when the front end portion 91a is pushed up. That is, the restricting plate 91 of the second restricting portion 9b swings so that the front end portion 91a faces upward and the rear end portion 91b faces downward. In this way, the rear end portion 91b gradually changes its position so as to be positioned below the rod protrusion 822b of the second sub rod 822.

  When the state change to the closed state of the lid 2 is completed, the rear end portion 91b is offset below the rod protrusion 822b. That is, at this time, the rear end portion 91b of the restricting plate 91 is detached from the rod protrusion 822b and deviates from the movement locus of the rod protrusion 822b. Then, the position of the rear end portion 91b changes to a position below the rod protruding portion 822b. Accordingly, the rear end portion 91b of the restricting plate 91 of the second restricting portion 9b deviates from the movement locus of the rod protrusion 822b, so that the movement of the second sub rod 822 is permitted. When the second auxiliary rod 822 becomes movable, the second auxiliary rod 822 moves forward according to the urging force of the second urging member 824. Further, at this time, the second rod 821 also moves rearward. Thus, the second auxiliary rod 822 and the second rod 821 move in directions away from each other according to the urging force of the second urging member 824. The distal end of the second secondary rod 822 projects forward from the lid body 4 and engages the front base 31, and the distal end of the second rod 821 projects from the arm 5 and engages the rear base 32.

  That is, in the closed state of the lid 2, the rear end portion 91 b of the restriction plate 91 of the second restriction portion 9 b deviates from the movement locus of the rod protrusion 822 b, and the movement of the second sub rod 822 is permitted. In other words, the action of the second restricting portion 9b that has maintained the second unlocked state is released. For this reason, the second lock mechanism 82 changes the state to the second lock state.

  In addition, the movement of the transmission rod 83 is permitted with the movement of the second sub rod 822 and the second rod 821 being permitted. When the second secondary rod 822 and the second rod 821 move away from each other according to the biasing force of the second biasing member 824, the second synchronization element 823 rotates counterclockwise, The supported transmission rod 83 also moves to the left as the second synchronization element 823 rotates counterclockwise. When the transmission rod 83 moves to the left, the transmission rod abutment portion 84a is disengaged from the movement locus of the engagement convex portion 812c provided on the first sub rod 812. Instead, the transmission rod engagement hole 84b faces the engagement convex portion 812c. In this way, the engagement convex portion 812c can enter and exit the transmission rod engagement hole 84b. That is, at this time, the movement of the first sub rod 812 is permitted and the first sub rod 812 and the first rod 811 can move in a direction approaching each other, so the first lock mechanism 81 is moved from the first lock state to the first lock. The state can be changed to the released state.

  Next, with reference to FIG.3 and FIG.5, the state change from the closed state of the lid 2 to a 2nd open state is demonstrated. In addition, each white arrow in FIG. 3 represents each moving direction of the 1st switch 86, the 1st subrod 812, and the 1st rod 811.

  First, the first lock state of the first lock mechanism 81 is changed to the first unlock state. That is, the operator presses the first switch 86 and moves it to the right. Then, the front end of the first sub rod 812 is detached from the front base 31 and the rear end of the first rod 811 is detached from the arm portion 5 by the same operation as the second switch 87. Thus, the first lock mechanism 81 is in the first unlocked state.

When the first lock mechanism 81 is in the first unlocked state, the second lock mechanism 82 and the second support shaft 7 provided on the right end side become the swing shaft, and the lid body portion according to the urging force of the second arm spring 71 4 swings in the opening direction. In this way, the lid main body portion 4 that is the lid 2 changes from the closed state to the second open state. Since the second support shaft 7 is provided with the second damper 73 similar to the first damper 63, the lid 2 in the second open state is the same as the swing of the lid 2 in the first open state. Can also be gently oscillated.

  Even in the second open state of the lid 2, the restricting portion 9 described in the first open state of the lid 2 is disposed in order to maintain the first unlocked state of the first lock mechanism 81. Therefore, even in the second open state of the lid 2, the first unlocking state of the first lock mechanism 81 is maintained by the first restricting portion 9a. On the other hand, as described below, the action of the transmission rod 83 prevents the second lock mechanism 82 from changing from the second locked state to the second unlocked state in the second open state of the lid 2.

  When the operator presses the first switch 86, the first lock mechanism 81 changes from the first locked state to the first unlocked state, and the first sub rod 812 and the first rod 811 move to the first biasing member 814. Move in a direction approaching each other against the biasing force. When the first sub rod 812 moves in the direction approaching the first rod 811, that is, in the rearward direction, the engagement convex portion 812 c provided on the first sub rod 812 is moved to the transmission rod engagement hole 84 b in the transmission rod tip 84. Inserted. Thus, in the 1st lock release state of the 1st lock mechanism 81, the engagement convex part 812c is the state inserted in the transmission rod engagement hole 84b.

  In the second open state of the lid 2, the first unlocking state of the first lock mechanism 81 is maintained by the first restricting portion 9a. For this reason, the movement of the first auxiliary rod 812 is prevented. Therefore, in the second open state of the lid 2, the state where the engagement convex portion 812 c of the first sub rod 812 is inserted into the transmission rod engagement hole 84 b is maintained.

  Due to the engagement between the engagement convex portion 812c and the transmission rod engagement hole 84b, the movement of the transmission rod 83 in the left-right direction is prevented. When the movement of the transmission rod 83 is blocked, the rotational movement of the second synchronization element 823 that supports the transmission rod 83 is also blocked. As a result, the movement of the second auxiliary rod 822 and the second rod 821 is also prevented, so that the second switch 87 cannot be pressed. Thus, the transmission rod 83 in the second open state prevents the second lock mechanism 82 from changing from the second locked state to the second unlocked state, and maintains the second locked state. As a result, in the lid mechanism 2 of the embodiment, it is possible to prevent the distal end of the second secondary rod 822 that is the swing shaft in the second open state from being detached from the front base 31, and thus the lid 2 is detached from the base 3. Thus, it is possible to prevent the box body 11 from coming off.

  With reference to FIG.3 and FIG.5, the state change from the 2nd open state of the lid 2 to a closed state is demonstrated. First, the operator presses the lid main body 4 against the urging force of the second arm spring 71. The lid body portion 4 swings until the opening of the storage portion 12 is shielded from the passenger compartment. Finally, the lid 2 is changed from the second open state to the closed state, the restriction by the first restriction portion 9a described below is released, and the first lock mechanism 81 changes from the first lock release state to the first lock state. .

  When the state of the lid 2 changes from the second open state to the closed state, the first restricting portion 9a provided on the left front side of the lid main body 4 is a state in which the lid 2 is changed from the first open state to the closed state. The same operation as when changing is performed. That is, the state change from the first unlocked state to the first locked state of the first lock mechanism 81 that has been blocked by the first restricting portion 9a in the closed state of the lid 2 is permitted, and the first lock mechanism 81 is The state changes from one unlocked state to the first locked state.

At this time, the first sub rod 812 and the first rod 811 are allowed to move, and accordingly, the transmission rod 83 is also allowed to move. That is, as the first sub rod 812 and the first rod 811 move away from each other according to the biasing force of the first biasing member 814, the first sub rod 812 moves forward, so that the transmission rod engaging hole 84b. The engaging convex portion 812c inserted in is detached from the transmission rod engaging hole 84b. Therefore, the engagement between the engagement convex portion 812c and the transmission rod engagement hole 84b is released, and the transmission rod 83 can move to the right. Therefore, the second synchronization element 823 supporting the transmission rod 83 can be rotated, and the second secondary rod 822 and the second rod 821 can also move. As a result, the second lock mechanism 82 can be changed from the second locked state to the second unlocked state.

  Hereinafter, effects in the embodiment will be described. In the lid mechanism 1 of the embodiment, the transmission rod 83 that prevents the first lock mechanism 81 and the second lock mechanism 82 from simultaneously changing to the unlocked state is disposed. In the embodiment, the transmission rod 83 is configured such that the right end side is supported by the second synchronization element 823 and the left end side is engageable with an engagement convex portion 812 c provided on the first sub rod 821. The transmission rod 83 moves in synchronization with the state change of the second lock mechanism 82 by the second synchronization element 823. As described above, the lid mechanism 1 according to the embodiment having the transmission rod 83 which is the erroneous operation preventing means is different from the erroneous operation preventing means of the lid mechanism disclosed in Patent Document 1, and has a structure that does not employ the cam mechanism. . Therefore, the transmission rod 83 as the erroneous operation preventing means of the embodiment has a simple configuration and improves the assemblability. Moreover, if it is the transmission rod 83 in embodiment, the coil spring of a cam mechanism like the switching means currently disclosed by patent document 1 can be abbreviate | omitted. Therefore, it is possible to effectively suppress the generation of noise due to rattling between components.

  In the lid mechanism 1 of the embodiment, a rotation mechanism is employed instead of the rack and pinion mechanism that has been conventionally used as a synchronization element. That is, in the lid mechanism 1 of the embodiment, the first synchronization element 813 of the first lock mechanism 81 and the second synchronization element 823 of the second lock mechanism 82 are both rotating bodies that are rotation mechanisms. Thereby, compared with the conventional structure which uses the gear in a rack and pinion mechanism for a synchronous element, the rattling resulting from meshing of a dentition can be suppressed effectively. Therefore, the lid mechanism 1 of the embodiment can effectively suppress the generation of abnormal noise due to rattling or the like.

  Furthermore, the transmission rod 83 in the embodiment is urged by the second urging member 824 via the second synchronization element 823 that is a rotating body. Therefore, the transmission rod 83 which is an erroneous operation preventing means is less likely to rattle. Similar to the transmission rod 83, the first sub rod 812 and the first rod 811 of the first lock mechanism 81 in the embodiment are urged to the first urging member 814 via the first synchronization element 813, and the second Since the second sub rod 822 and the second rod 821 of the lock mechanism 82 are urged by the second urging member 824 via the second synchronization element 823, it is difficult to rattle.

  In the lid mechanism 1 of the embodiment, the arm portion 5 is arranged in parallel on the rear end side of the lid main body portion 4, and the first support shaft 6 and the second support shaft 7 are respectively provided on the left and right end portions of the arm portion 5 and the rear base portion 32. It is arranged. Therefore, the lid 2 including the lid body 4 and the arm 5 swings from the right end side with respect to the base 3, and the lid body 4 swings from the left end with respect to the arm 5 and base 3. This arm portion 5 realizes an alternative opening / closing operation from the left end side or the right end side of the lid 2. Therefore, according to the lid mechanism 1 of the embodiment, the number of the two arm portions arranged in the conventional double-opening type storage box can be made only one. Therefore, the number of parts can be reduced. Further, by using one arm part 5, it is possible to reduce the space on the box body 11 side for arranging the arm part 5. Therefore, it is possible to increase the box capacity of the storage unit 12 provided in the box body 11 and to increase the opening area of the storage unit 12.

In the lid mechanism 1 of the embodiment, the arm portion 5 is disposed only on the rear end side of the storage portion 12. That is, there is no arm portion on the front end side of the storage portion 12. Therefore, since it is possible to improve the appearance of the front end side of the storage portion 12, it is also possible to improve the appearance of the storage portion 12 when the lid is opened.

  In the lid mechanism 1 of the embodiment, a swing shaft for swinging the lid 2 is provided on both left and right ends of the arm portion 5. The swing shaft on the left end side of the arm portion 5 is the first support shaft 6 and is inserted through the arm portion 5 and the rear base portion 32. The swing shaft on the right end side of the arm portion 5 is the second support shaft 7 and is inserted through the arm portion 5 and the lid main body portion 4. As described above, by providing the swing shafts so as to be offset at the left and right ends of the arm portion 5, when the lid 2 swings, one swing shaft that is not the swing shaft is attached and detached. Do not take. Therefore, the position of the swing shaft is always fixed. Therefore, the lid mechanism 1 according to the embodiment is advantageous in suppressing abnormal noise such as positional deviation or breakage of the rocking shaft or rattling caused by the detachable rocking shaft.

  As mentioned above, although preferred embodiment of this invention was described in detail based on drawing, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary.

  For example, the base 3 in the embodiment is integrated with the box body 11, but the base 3 may be the box body 11. Moreover, although the lid 2 in the embodiment is supported by the front base portion 31 and the rear base portion 32, the lid 2 may be configured to be supported by either one.

  The arm portion 5 in the embodiment is disposed on the rear end side of the storage portion 12, but may be disposed on the front end side.
