  First, the second lock state of the second lock mechanism 82 is changed to the second unlocked state. That is, the operator presses the second switch 87 to move 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 protrusion 822a to the left. At this time, since the notch 87a is inclined from the left front to the right rear, the protrusion 822a moves rearward in the notch 87a. Therefore, the second auxiliary rod 822 having the convex portion 822a also moves rearward. As described above, the notch 87a provided on the second switch 87 converts the leftward force from the operator into the backward force, and moves the second sub rod 822 having the convex portion 822a backward. Let it.

  As the second sub rod 822 moves rearward, the second synchronization element 823 supporting the second sub 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 by the clockwise rotation of the second synchronization element 823. Thereby, the front end of the second sub 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 second lock mechanism 82 changes from the second locked state to the second unlocked state. In the second locked state, the second sub-rod 822 receives the urging force from the second urging member 824 that moves forward via the second synchronization element 823. Therefore, the operator presses the second switch 87 with a force opposing 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 enters the second unlocked state, the lid body 4 and the arm 5 swing together 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 lock state, the front end of the first auxiliary rod 812 provided on the left end side and the first support shaft 6 become the swing shaft of the lid 2. Thus, the state of the lid 2 changes 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 5 and the lid main body 4 are connected and integrated at the left end and the right end, respectively. Specifically, since the first lock mechanism 81 is in the first lock state, the first rod 811 is engaged with the arm 5. As described above, the arm 5 and the lid body 4 are connected to each other on the left end sides by the first rod 811.

  The front end of the collar 72 inserted into the second arm through hole 52 extends to the lid main body 4, and supports the lid main body 4 in a rotatable (swingable) manner. As described above, the arm 5 and the lid main body 4 are connected to each other by the collar 72 on the right end sides thereof. When the lid 2 changes from the closed state to the first open state, the second lock mechanism 82 is in the second unlocked state. At this time, the second rod rear end 821a of the second rod 821 has been separated from the rear base 32. The rear end 821 a of the second rod is housed inside the arm 5 and located in the second arm through-hole 52.

  As described above, the arm 5 and the lid main body 4 are connected to each other on the left end side and the right end side, respectively, so as to be integrated. Therefore, when the state of the lid 2 changes from the closed state to the first open state, the arm 5 and the lid main body 4 swing together. In this case, since the arm portion 5 swings, 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 secure a large opening area of the storage portion 12. Further, since the arm portion 5 does not remain on the box main body 11, the appearance of the storage portion 12 is improved.

  The transmission rod 83 is provided in the lid mechanism 1 of the embodiment. When the operator presses the second switch 87, the second sub rod 822 and the second rod 821 move in directions 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 rightward, the transmission rod abutting portion 84a at the transmission rod distal end portion 84 faces the engaging projection 812c provided on the first sub rod 812. At this time, the transmission rod contact portion 84a is located on the front side on the movement locus of the engagement convex portion 812c.

  Since the transmission rod contact portion 84a is located on the front side of the movement trajectory of the engagement projection 812c, the rearward movement of the first auxiliary rod 812 is prevented. This is because when the first sub-rod 812 attempts to move rearward from the first locked state, the engaging projection 812c of the first sub-rod 812 moves to the transmission rod contact portion 84a located on the front side on the movement trajectory. In order to abut. That is, the transmission rod contact portion 84a prevents the first auxiliary rod 812 from moving rearward through the engagement protrusion 812c.

  When the backward movement of the first auxiliary rod 812 is prevented, the movement of the first rod 811 synchronized with the first auxiliary rod 812 by the first synchronization element 813 is also prevented. Accordingly, in the first open state, when the second lock release state of the second lock mechanism 82 is maintained by the second restriction part 9b of the restriction part 9 as described later, the first lock state of the first lock mechanism 81 is maintained. Cannot be canceled. 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 present embodiment, the front end of the first sub rod 812 serving as the swing axis separates from the front base 31, and the rear end of the first rod 811 separates from the arm 5. Can be prevented, and the lid 2 can be prevented from detaching from the base 3 and coming off the box body 11.

  In the lid mechanism 1 of the present embodiment, the lid main body 4 is provided with the restricting portion 9. By the way, as described above, when the operator presses the second switch 87, the second lock mechanism 82 changes from the second lock state to the second unlock state, and accordingly, the transmission rod 83 moves to the second lock state. The state change of the one lock mechanism 81 from the first locked state to the first unlocked state is prevented. However, in a case where the regulating portion 9 is not provided, when the operator releases the pressing on the second switch 87, the second unlocked state changes to the second locked state according to the urging force of the second urging member 824. Resulting in. Accordingly, since the transmission rod 83 returns to the original position, the prevention 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 change its state to the first unlocked state. In this case, since the first lock mechanism 81 and the second lock mechanism 82 can be in the unlocked state at the same time, the lid 2 may be detached from the base 3. Therefore, when the lid 2 is swung about the front end of the first auxiliary rod 812 and the first support shaft 6 as the swing axis, and is in the first open state, the second lock mechanism 82 shifts from the second unlocked state to the second lock state. A second restricting portion 9b for preventing a state change to a state is provided. 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 regulating unit 9b will be described.

  In the second regulating portion 9b, the front end portion 91a and the rear end portion 91b of the regulating plate 91 tilt in a seesaw shape. The regulating plate 91 is urged by the regulating plate urging portion 92 such that the front end portion 91a faces downward. In the closed state of the lid 2, the front end portion 91 a of the regulating 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 regulating plate urging portion 92. At this time, the regulating plate 91 is located such that the rear end 91b is lower than the front end 91a, and the rear end 91b of the regulating plate 91 is located below the rod projection 822b. That is, at this time, since the rear end portion 91b and the rod protrusion 822b are offset from each other in the height direction, the rear end 91b of the regulating plate 91 and the rod protrusion 822b are engaged. Absent.

  When the lid 2 in the closed state changes to the first open state, the second auxiliary rod 822 of the second lock mechanism 82 has moved rearward. Further, the second restricting portion 9 b located at the front right end of the lid main body 4 changes its position together with the lid main body 4 and moves away from the front base 31. When the second regulating portion 9b moves away from the front base 31, the regulating plate 91 of the second regulating portion 9b has its front end 91a downward and its rear end 91b upward according to the urging force of the regulating plate urging portion 92. Rocks to face. As a result, the rear end portion 91b of the regulating plate 91 is located on the movement trajectory of the rod projection 822b of the second sub rod 822 that has moved backward. Accordingly, the rod protrusion 822b is thereby in a state capable of engaging with the rear end 91b of the regulating 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. Thereafter, when the operator releases the second switch 87, the operator presses the second switch 87 to move in a direction approaching each other against the urging force of the second urging member 824. 822 and the second rod 821 return to their original positions. That is, the second sub-rod 822 and the second rod 821 move in directions away from each other. When the second sub rod 822 and the second rod 821 return to the original positions, the second switch 87 also returns to the original position.

  Here, when the state of the lid 2 changes from the closed state to the first open state, the position of the rear end portion 91b of the regulating plate 91 of the second regulating portion 9b changes so that the rear end portion 91b can engage with the rod projection 822b. That is, at this time, the forward movement of the second sub rod 822 is prevented by the engagement between the rear end portion 91b and the rod projection 822b. Therefore, the forward movement of the second sub-rod 822 and the backward movement of the second rod 821 according to 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 unlocked 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 swing speed of the lid 2 is provided. Therefore, since the lid 2 can be gently swung, the lid mechanism 1 according to the present embodiment can produce a sense of quality.

  The state change of the lid 2 from the first open state to the closed state will be described with reference to FIGS. First, the operator presses the lid 2 in which the arm 5 and the lid body 4 are integrated with each other against the urging force of the first arm spring 61. Then, the lid 2 swings until the opening of the storage section 12 is shielded from the vehicle interior. Finally, the lid 2 is changed from the first open state to the closed state, the restriction by the second restricting portion 9b described below is released, and the second lock mechanism 82 changes from the second unlocked state to the second locked state. .

  When the state of the lid 2 changes from the first open state to the closed state, the second restricting portion 9 b provided on the right front of the lid body 4 approaches the front base 31. In the first open state, the regulating plate 91 of the second regulating portion 9b is inclinedly arranged with the rear end portion 91b facing upward and the front end portion 91a facing downward by the regulating plate urging portion 92. The rear end portion 91b of the regulating plate 91 is engaged with the rod projection 822b, and the front end portion 91a of the regulating plate 91 projects forward from the lid body 4. That is, at this time, the second restricting portion 9b maintains the second lock release state of the second lock mechanism 82, and as a result, the transmission rod 83 moves from the first lock 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 regulating plate 91 of the second regulating portion 9b comes into contact with the front base 31. Thereafter, with the swing of the lid 2 toward the closed state, the front end 91a is gradually pushed up to the front base 31. On the other hand, the rear end portion 91b, which has been lifted in accordance with the urging force of the regulating plate urging portion 92, is pushed down against the urging force of the regulating plate urging portion 92 when the front end portion 91a is pushed up. That is, the regulating plate 91 of the second regulating portion 9b swings so that the front end 91a faces upward and the rear end 91b faces downward. Thus, the rear end portion 91b gradually changes its position so as to be located below the rod projection 822b of the second sub rod 822.

  When the state change of the lid 2 to the closed state is completed, the rear end portion 91b is offset below the rod projection 822b. That is, at this time, the rear end portion 91b of the regulating plate 91 is separated from the rod projection 822b and deviates from the movement locus of the rod projection 822b. Then, the position of the rear end portion 91b changes to a position below the rod protrusion 822b. Therefore, since the rear end portion 91b of the regulating plate 91 of the second regulating portion 9b deviates from the movement locus of the rod protrusion 822b, the movement of the second sub-rod 822 is permitted. When the second sub rod 822 becomes movable, the second sub 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 backward. Thus, the second sub-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 tip of the second sub rod 822 projects forward from the lid body 4 and engages with the front base 31, and the tip of the second rod 821 projects from the arm 5 and engages with the rear base 32.

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

  In addition, as the movement of the second sub-rod 822 and the second rod 821 is permitted, the movement of the transmission rod 83 is also permitted. When the second sub-rod 822 and the second rod 821 move in a direction away from each other according to the urging force of the second urging member 824, the second synchronizing element 823 rotates counterclockwise. The supported transmission rod 83 also moves to the left with the counterclockwise rotation of the second synchronization element 823. When the transmission rod 83 moves to the left, the transmission rod contact portion 84a is displaced from the movement locus of the engaging projection 812c provided on the first sub rod 812. Instead, the transmission rod engagement hole 84b faces the engagement projection 812c. Thus, the engaging projection 812c can enter and exit the transmission rod engaging 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 the direction approaching each other. The state can be changed to the release state.

  Next, a state change of the lid 2 from the closed state to the second open state will be described with reference to FIGS. Note that each white arrow in FIG. 3 indicates a moving direction of each of the first switch 86, the first sub rod 812, and the first rod 811.

  First, the first lock state of the first lock mechanism 81 is changed to the first unlocked state. That is, the operator presses the first switch 86 to move it to the right. Then, by the same operation as the second switch 87, 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 5. Thus, the first lock mechanism 81 enters 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 serve as a swing shaft, and the lid main 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 4, which is the lid 2, changes its state 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 similar to the swing of the lid 2 in the first open state. Can also be gently performed.

  In the second open state of the lid 2 as well, the restricting section 9 described in the first open state of the lid 2 is provided to maintain the first lock mechanism 81 in the first unlocked state. Therefore, even in the second open state of the lid 2, the first lock release state of the first lock mechanism 81 is maintained by the first restricting portion 9a. On the other hand, as described below, the operation 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 opened 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 are connected to the first urging member 814. They move in directions 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 engaging projection 812 c provided on the first sub-rod 812 is moved to the transmission rod engaging hole 84 b in the transmission rod distal end portion 84. Inserted. As described above, in the first unlocked state of the first lock mechanism 81, the engagement projection 812c is in a state of being inserted into the transmission rod engagement hole 84b.

  In the second opened state of the lid 2, the first unlocked state of the first lock mechanism 81 is maintained by the first restricting portion 9a. Therefore, the forward movement of the first sub rod 812 is prevented. Therefore, in the second opened state of the lid 2, the state in which the engagement projection 812c of the first sub rod 812 is inserted into the transmission rod engagement hole 84b is maintained.

  The engagement of the engagement projection 812c and the transmission rod engagement hole 84b prevents the transmission rod 83 from moving in the left-right direction. When the movement of the transmission rod 83 is blocked, the rotational movement of the second synchronization element 823 supporting the transmission rod 83 is also blocked. As a result, the movement of the second sub-rod 822 and the second rod 821 is also prevented, so that the second switch 87 cannot be pressed. In this way, the transmission rod 83 in the second open state prevents the state of 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 1 of the embodiment, it is possible to prevent the distal end of the second sub-rod 822 serving as the swing axis from being detached from the front base 31 in the second open state, and thus the lid 2 is detached from the base 3. As a result, it is possible to prevent the box body 11 from coming off.

  A state change of the lid 2 from the second open state to the closed state will be described with reference to FIGS. First, the operator presses the lid body 4 against the urging force of the second arm spring 71. The lid body 4 swings until the opening of the storage section 12 is shielded from the vehicle interior. Finally, the lid 2 changes from the second open state to the closed state, the restriction by the first restricting portion 9a described below is released, and the first lock mechanism 81 changes from the first unlocked state to the first locked state. .

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

  At this time, the movement of the first sub rod 812 and the first rod 811 is permitted, and accordingly, the movement of the transmission rod 83 is also permitted. That is, the first sub rod 812 and the first rod 811 move in a direction away from each other according to the urging force of the first urging member 814, and the transmission rod engaging hole 84b The engagement projection 812c inserted into the transmission rod is separated from the transmission rod engagement hole 84b. Accordingly, the engagement between the engaging projection 812c and the transmission rod engaging hole 84b is released, and the transmission rod 83 can move rightward. Therefore, the rotational movement of the second synchronization element 823 supporting the transmission rod 83 is enabled, and the second sub rod 822 and the second rod 821 are also movable. As a result, the state of the second lock mechanism 82 can be changed from the second locked state to the second unlocked state.

  Hereinafter, effects of the embodiment will be described. In the lid mechanism 1 of the embodiment, the arm portion 5 is arranged side by side on the rear end side of the lid body portion 4, and the first support shaft 6 and the second support shaft 7 are provided on the left and right end portions of the arm portion 5 and the rear base 32, respectively. It is arranged. Therefore, the lid 2 including the lid body 4 and the arm 5 swings from the right end with respect to the base 3, and the lid body 4 swings from the left end with respect to the arm 5 and the base 3. The 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 arms provided in the conventional double-sided storage box can be reduced to only one. Therefore, the number of parts can be reduced. In addition, by using one arm 5, it is possible to reduce the space on the box body 11 side for disposing the arm 5. Therefore, it is possible to increase the box capacity of the storage section 12 provided in the box body 11, and it is possible to increase the opening area of the storage section 12.

  Further, in the lid mechanism 1 of the embodiment, the arm 5 is provided only on the rear end side of the storage section 12. That is, the arm part 5 does not exist on the front end side of the storage part 12. Therefore, the appearance of the front end side of the storage section 12 can be improved, so that the appearance of the storage section 12 when the lid is opened can also be improved.

  In the lid mechanism 1 of the present embodiment, a swing shaft for swinging the lid 2 is provided on both left and right sides of the arm 5. The swing shaft on the left end side of the arm 5 is a first support shaft 6, which is inserted through the arm 5 and the rear base 32. The swing shaft on the right end side of the arm 5 is a second support shaft 7, which is inserted through the arm 5 and the lid body 4. In this manner, by providing the swing shafts at the left and right ends of the arm portion 5 so as to be offset from each other, one swing shaft that is not the swing shaft can be detached when the lid 2 swings. Do not take. Therefore, the arrangement position of the swing shaft is always fixed. Therefore, the lid mechanism 1 of the embodiment is advantageous in suppressing abnormal noise such as displacement or breakage of the swing shaft or rattling caused by the detachable swing shaft.

  In the lid mechanism 1 of the present embodiment, a rotation mechanism is adopted instead of the rack and pinion mechanism 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. As a result, rattling due to meshing of the teeth can be effectively suppressed as compared with a conventional structure using a gear in a rack-and-pinion mechanism as a synchronization element. Therefore, according to the lid mechanism 1 of the embodiment, generation of abnormal noise due to rattling or the like can be effectively suppressed.

  In the lid mechanism 1 of this embodiment, the transmission rod 83 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 the erroneous operation prevention means, is less likely to rattle. Similarly to the transmission rod 83, the first auxiliary rod 812 and the first rod 811 of the first lock mechanism 81 in the embodiment are urged by the first urging member 814 via the first synchronization element 813, and Since the second auxiliary 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, the rattle is less likely to rattle.

  In the lid mechanism 1 of this embodiment, the transmission rod 83 connected to the second synchronizing element 823 is used as an erroneous operation preventing means for preventing both the left and right lock mechanisms 8 from being unlocked simultaneously. Such an erroneous operation prevention means has two lock mechanisms and a switching means as conventionally disclosed in, for example, JP-A-2013-220709.

  Each of the two lock mechanisms has a bar lock pin structure including a front lock pin, a rear lock pin, and a link body for synchronizing the front lock pin and the rear lock pin. With 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 be a swing shaft. On the other hand, when the lid swings from the other end, the lock mechanism on the other end is unlocked, and the lock mechanism on the one end is in a locked state, thus forming a swing shaft.

  However, with only such two lock mechanisms, there is a possibility that when the lid is rocking, the lock mechanism serving as the rocking axis is unlocked due to an erroneous operation of the operator. That is, there is a possibility that the two lock mechanisms may be in the unlocked state at the same time, and there is a problem that the lid comes off the box body. In order to solve such a problem, in the double-sided storage box disclosed in Japanese Patent Application Laid-Open No. 2013-220709, the lid can be selectively rocked from one end side or the other end side, and one lock mechanism is provided with a rocking shaft. A switching means capable of maintaining the locked state of the lock mechanism when is established.

  The switching means includes a connecting rod that connects the two lock mechanisms in a bridge shape, and a centering member that engages with a central portion of the connecting rod. The connecting rod is supported by the lid so as to be movable toward one end or the other end. By moving the connecting rod toward one end or the other end, when the lid is swinging, one lock mechanism serving as the swing axis of the lid maintains the locked state. The centering member is constituted by a cam mechanism having a coil spring. In a state where the lid is closed, the centering member returns the connecting rod moved toward one end or the other end to the neutral position by the urging force of the coil spring. Thus, when the lid is closed, the locked state of one of the two lock mechanisms can be released again.

  As described above, the switching means disclosed in Japanese Patent Application Laid-Open No. 2013-220709 can selectively swing the lid from one end side or the other end side, and one of the lock mechanisms serving as a swing axis. Is prevented from changing from the locked state to the unlocked state. Therefore, according to the switching means disclosed in Japanese Patent Application Laid-Open No. 2013-220709, it is possible to solve the problem that the lid comes off the box when the lid swings.

  However, the switching mechanism disclosed in JP-A-2013-220709 employs a cam mechanism using a coil spring as a centering member. For this reason, the structure was complicated and assembly was troublesome.

  Therefore, the lid mechanism 1 of the present embodiment uses the transmission rod 83 instead of the cam mechanism using the coil spring. Therefore, the structure is simplified and the assembling property is improved. More specifically, the transmission rod 83 in the embodiment is configured such that the right end is supported by the second synchronization element 823 and the left end is engageable with the engagement protrusion 812c provided on the first auxiliary rod 812. . The transmission rod 83 is moved by the second synchronization element 823 in synchronization with the state change of the second lock mechanism 82. As described above, the lid mechanism 1 of the embodiment having the transmission rod 83 as the erroneous operation prevention means has a structure in which the cam mechanism is not used as the erroneous operation prevention means. Therefore, in the embodiment, the transmission rod 83 serving as the erroneous operation prevention means can contribute to the reduction of the number of components, and the simple structure is advantageous in improving the assemblability.

(Second embodiment)
In the first embodiment, the swing speed of the lid 2 is reduced by the first damper 63 or the second damper 73, but a swing speed reducing element 100 may be used instead. Hereinafter, the swing deceleration element 100 will be described as the lid mechanism 1 of the second embodiment with reference to FIG.

  The swing deceleration element 100 reduces the rotation speed of the support shaft 10 to reduce the swing speed of the lid 2. The swing deceleration element 100 is provided on each of the first support shaft 6 side and the second support shaft 7 side. The swing deceleration element 100 on the first support shaft 6 side reduces the rotation speed of the first support shaft 6 and the swing speed of the lid 2. The swing deceleration element 100 on the side of the second support shaft 7 reduces the rotation speed of the second support shaft 7 and the swing speed of the lid 2. The configuration of the swing deceleration element 100 is the same on both the first support shaft 6 side and the second support shaft 7 side. Therefore, as shown in FIG. 8, the swing deceleration element 100 on the first support shaft 6 side will be described.

  The swing reduction element 100 includes a first gear 110 provided on the first support shaft 6, a second gear 120 meshing with the first gear 110, and a damper connected to the second gear 120 via a connection gear 180. 170. The connection gear 180 in the present embodiment includes a third gear 130, a fourth gear 140, a fifth gear 150, and a sixth gear 160, which will be described later.

  The first gear 110 is provided coaxially with the first support shaft 6 and integrally therewith. The first gear 110 rotates in conjunction with the swing of the lid 2. The first gear 110 in this embodiment is a conical gear, and is a straight bevel gear with straight teeth. The first gear 110 meshes with a second gear 120 that is a conical gear described later to form a bevel gear.

  The second gear 120 is the same bevel gear as the first gear 110. As described above, the first gear 110 and the second gear 120 constitute a bevel gear, and the rotation axis of the first gear 110 and the rotation axis of the second gear 120 are arranged in directions intersecting each other. I have. In this embodiment, the rotation axis of the first gear 110 and the rotation axis of the second gear 120 are arranged in a direction orthogonal to each other. The second gear 120 is rotatably supported by a first rotation shaft 123 supported by the rear base 32.

  The third gear 130 is rotatably supported by the first rotation shaft 123, and is integrated with the second gear 120. That is, the third gear 130 is coaxially integrated with the second gear 120. The third gear 130 in the present embodiment is a fan-shaped spur gear having a larger diameter than the second gear 120. The row of teeth 130a of the third gear 130 is formed on an arc. The teeth portion 130 a of the third gear 130 meshes with the fourth gear 140.

  The fourth gear 140 is rotatably supported by a second rotation shaft 145 supported by the rear base 32. The fourth gear 140 is a spur gear, and has a smaller diameter and fewer teeth than the third gear 130. The fifth gear 150 is a spur gear, is rotatably supported by the second rotation shaft 145, and is integrated with the fourth gear 140. That is, the fifth gear 150 is coaxially integrated with the fourth gear. The fifth gear 150 has a larger diameter and a larger number of teeth than the fourth gear 140. In the embodiment, the fourth gear 140 and the fifth gear 150 constitute a two-stage gear train. The fifth gear 150 meshes with the sixth gear 160.

  The sixth gear 160 is a spur gear, and is rotatably supported by the damper 170 by the third rotation shaft 167. The sixth gear 160 has fewer teeth than the fifth gear 150. The sixth gear 160 preferably has the same number of teeth as the fourth gear 140 or has fewer teeth than the fourth gear 140.

  The damper 170 is fixed to the rear base 32. The damper 170 includes a sealed container (not shown) filled with oil, a rotating body (not shown) rotatably provided in the sealed container, and a rotating shaft rotatably supporting the rotating body and penetrating outside the sealed container. (Not shown), and the rotation of the rotating body is braked by viscous resistance of the oil. In this embodiment, the rotation axis of the damper 170 coincides with the third rotation axis 167 that supports the sixth gear 160. That is, the damper 170 brakes the rotation of the sixth gear 160 via the third rotation shaft 167.

  In the swing deceleration element 100 of the embodiment configured as described above, the swing of the lid 2 causes the first gear 110 provided on the first support shaft 6 to rotate, and the second gear 120 and the third gear The sixth gear 160 connected to the damper 170 rotates via the 130, the fourth gear 140, and the fifth gear 150. Since the rotation of the sixth gear 160 is braked by the damper 170, the swing speed of the lid 2 is reduced.

  By the way, in the lid mechanism 1 of the first embodiment, the gears (the first damper gear 63a and the second damper gear 73a, which will be hereinafter referred to as damper gears) directly connected to the damper, and the gear ( The shaft tooth row 6a and the collar tooth row 72a, hereinafter referred to as support shaft gears) are spur gears. In such a case, the diameters of the damper gear and the support shaft gear are both limited by the thickness of the lid mechanism 1. Here, the thickness of the lid mechanism 1 means the size in the vertical direction when the lid 2 is closed. That is, it means a direction from the near side to the far side in FIG. The support shaft 10 is arranged to extend in the front-rear direction.

  For example, in a thin lid mechanism in which the thickness of the lid mechanism is reduced, the sizes of the diameters of the spur gear damper gear and the support shaft gear in the lid mechanism 1 of the first embodiment are particularly limited. If the diameters of the damper gear and the support shaft gear are restricted, a sufficient gear ratio between the damper gear and the support shaft gear cannot be secured, and the rotational speed of the damper gear decreases. There is a risk of becoming. If the rotational speed of the damper gear decreases, the damper may not be able to exert a deceleration torque sufficient to sufficiently reduce the swing speed of the lid 2.

  However, according to the oscillating deceleration element 100 in the second embodiment, the rotation axes of the first gear 110 having the support shaft 10 as the rotation axis and the second gear 120 meshing with the first gear 110 cross each other. Are engaged so that they face each other. That is, the first gear 110 and the second gear 120 are engaged with each other so that the respective extension lines of the support shaft 10 (the first support shaft 6 and the second support shaft 7) and the first rotation shaft 123 intersect. I have. If the second gear 120 can be arranged with respect to the first gear 110 in this way, the radial direction of the second gear 120 does not have to be oriented in the thickness direction of the lid mechanism 1. That is, the radial size of the second gear 120 is not restricted by the thickness of the lid mechanism 1. Therefore, as shown in FIG. 8, the spur gears (the third gear 130 to the sixth gear 160), which are the connection gears 180 connectable to the second gear 120, can also be arranged without being limited by the thickness of the lid mechanism 1.

  As described above, in the second embodiment, since the connecting gear 180 can be configured without being restricted by the thickness of the lid mechanism 1, the coupling gear 180 directly connected to the first gear 110, which is the driving source, and the damper 170 is connected. The gear ratio with the sixth gear 160 as the driving source can be designed to be large. That is, the rotation speed of the sixth gear 160 can be increased. Thus, in the swing deceleration element 100 according to the embodiment, the deceleration torque by the damper 170 can be sufficiently increased, which is advantageous in effectively reducing the swing speed of the lid 2. In addition, according to the swing deceleration element 100 of the embodiment, since a thin lid can be realized, effects such as improvement in design and reduction in product weight can be achieved.

  In the oscillating reduction element 100 according to the present embodiment, the number of teeth of the gear train 130 a of the third gear 130 and the number of teeth of the fifth gear 150 are set to be smaller than the number of teeth of the fourth gear 140 and the number of teeth of the sixth gear 160. It is desirable to have enough. By configuring the connecting gear 180 in this manner, the rotation speed of the sixth gear 160 connected to the damper 170 can be sufficiently increased, and the swing speed of the lid 2 can be effectively reduced.

  In addition, the first gear 110 and the second gear 120 in this embodiment both constitute a bevel gear using a bevel gear. That is, it is desirable that the rotation axes of the first gear 110 and the second gear 120 are provided to be orthogonal to each other (the axis angle is 90 °). However, the axis angle between the first gear 110 and the second gear 120 may be 90 ° ± 20 °. Further, the gears of the first gear 110 and the second gear 120 may be spiral bevel gears. Further, the first gear 110 and the second gear 120 may be of a staggered shaft such as a screw gear instead of the above-described cross shaft.

  As described above, the preferred embodiments of the present invention have been described in detail with reference to the drawings. However, the present invention is not limited to the above embodiments, and can be variously modified without departing from the gist thereof.

  For example, the base 3 in the embodiment is assembled to the box main body 11 to be integral, but the base 3 may be the box main body 11. Further, the lid 2 in the embodiment is supported by the front base 31 and the rear base 32, but may be configured to be supported by either one. That is, the lid 2 may have a configuration in which the lid body 4 is supported by the rear base 32 via the arm 5.

  Although the arm portion 5 in the embodiment is disposed on the rear end side of the storage portion 12, it may be disposed on the front end side. Further, the first arm spring 61 and the second arm spring 71 are provided on both left and right end sides of the arm portion 5, but these may be omitted or one of them may be provided. Further, the first arm spring 61 and the second arm spring 71 may be, for example, a turnover spring that biases in both the opening direction and the closing direction. Although the first damper 63 and the second damper 73 are provided on both left and right ends of the arm portion 5, these may be omitted.

  The second support shaft 7 in the embodiment is a collar 72. However, the collar 72 can be omitted. In this case, the second support shaft 7 is a second rod rear end 821a that can be engaged with the rear base 32. That is, a part of the lock mechanism 8 can be a part of the support shaft 10.

  The lock mechanism 8 in the embodiment has a structure in which the lock is released when the front and rear rods move in directions approaching each other. That is, the lock mechanism 8 may have a so-called bar lock structure, and the configuration is not particularly limited. For example, the mechanism for rotating the rotating body and the rod in the embodiment may be a rack and pinion mechanism.

  The transmission rod distal end portion 84 of the transmission rod 83 in the embodiment includes a transmission rod contact portion 84a and a transmission rod engagement hole 84b. The transmission rod engaging hole 84b in the embodiment is a through hole, but may be a concave portion that allows the first auxiliary rod 812 of the first lock mechanism 81 to move back and forth. Further, instead of the transmission rod distal end portion 84 and the engagement projection 812c of the first sub rod 812 in the embodiment, for example, the engagement projection 812c of the first sub rod 812 corresponds to the transmission rod contact portion 84a. The projecting portion may have a contact portion and an engaging hole corresponding to the transmitting rod engaging hole 84b, and the transmitting rod tip portion 84 may be an engaging convex portion corresponding to the engaging convex portion 812c of the first sub rod 812. . In this case, when the first lock mechanism 81 is in the first unlocked state, the engagement hole of the first auxiliary rod 812 and the engagement protrusion of the transmission rod 83 are engaged, and the state of the transmission rod 83 is prevented from changing. As a result, the second lock mechanism 82 is prevented from changing from the second locked state to the second unlocked state. When the second lock mechanism 82 is in the second unlocked state, the engaging projection of the transmission rod 83 is located on the movement trajectory of the contact portion of the first sub rod 812, and prevents the movement of the first sub rod 812. I do. As a result, the first lock mechanism 81 is prevented from changing from the first locked state to the first unlocked state.

  In the embodiment, the transmission rod 83 and the engagement protrusion 812c are provided as the erroneous operation prevention structure, but these may be omitted. Further, in the embodiment, the regulating unit 9 is provided, but the regulating unit 9 may be omitted.

  Even if each configuration in the embodiment is changed as described above, the problem of the present invention can be solved and the effects of the present invention can be achieved.
