Description

[Technical Field]

[0001] The present invention relates to an improvement in a storage device that is installed in the interior of a vehicle such as a passenger car and is used to store various items in a state that allows them to be easily taken out as needed. [Background technology]

[0002] There is a console lid that constitutes a console box, which is divided into a front half and a rear half, so that when the front end of the lid is pushed backward, the lid folds backward, and when the rear end of the lid is pushed forward, the lid folds forward (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 4-31638 Summary of the Invention [Problem to be solved by the invention]

[0004] The main problem that this invention aims to solve is to provide a new structure that rationally improves the usability and design of a lid member that constitutes a storage device such as a console box, which is made up of two or more lid structures, or a new structure that allows the lid member to operate appropriately. [Means for solving the problem]

[0005] In order to achieve the above object, the present invention provides a storage device comprising: a storage device body having an opening and a guide rail; a lid member that closes the opening in the unfolded state and has a guided portion for the guide rail on a first side portion facing the guide rail, the lid member is formed by connecting two or more lid structures, each having the guided portion, via a shaft, and is configured such that in the unfolded state, the lid structures are positioned flush with each other to close the opening, and in the folded state, the lid member is bent about the shaft to open the opening, the storage device body is provided with a capturing mechanism that captures the captured portion formed on the first side portion of the lid member in the deployed state, and a release mechanism that releases the capture by operation, The lid member is provided with a biasing mechanism that biases the lid structure so as to transition the lid member to the folded state when the capture is released, and a damper mechanism that brakes the movement of the lid structure due to the biasing of the biasing mechanism.

[0006] One aspect of this invention is to form the captured portion at a position that is the center of the mountain fold in the lid member in the folded state, or at a position in one of the lid structures where the distance between the guided portion and the central position is smaller than the distance between the guided portion and the central position.

[0007] The lid member further includes the guided portions on both sides of the shaft body in the first side portion, The storage device main body has a first engagement portion that engages with the guided portion located on one side of the shaft when the lid member is in the unfolded state, and a second engagement portion that engages with the guided portion located on the other side of the shaft; a first operating mechanism that enables the first engaging portion to be disengaged from the engagement, and a second operating mechanism that enables the second engaging portion to be disengaged from the engagement, One aspect of this invention is that when the engagement of the first engagement portion is released by operating the first operating mechanism, the capture by the capture mechanism is released while the engagement of the second engagement portion is maintained, and when the engagement of the second engagement portion is released by operating the second operating mechanism, the capture by the capture mechanism is released while the engagement of the first engagement portion is maintained, so that the first operating mechanism and the second operating mechanism constitute part of the release mechanism.

[0008] The lid member further includes auxiliary guided portions located on a virtual straight line passing through the guided portions on both sides of the shaft at a second side portion located opposite the first side portion, the storage device main body includes a first holding portion that houses the auxiliary guided portion located on one side of the shaft body in the unfolded state, a second holding portion that houses the auxiliary guided portion located on the other side of the shaft body in the unfolded state, and an auxiliary guide rail for the auxiliary guided portion that spans between the first holding portion and the second holding portion, When the engagement of the first engagement portion is released by operating the first operation mechanism, the auxiliary guided portion housed in the first holding portion enters the auxiliary guide rail to allow movement of the lid structure toward the folded state, and the auxiliary guided portion housed in the second holding portion is held within the second holding portion, One aspect of the present invention is that when the engagement of the second engagement portion is released by operating the second operating mechanism, the auxiliary guided portion housed in the second holding portion enters the auxiliary guide rail, allowing the lid structure to move toward the folded state, and the auxiliary guided portion housed in the first holding portion is held within the first holding portion.

[0009] The capturing mechanism also includes a first portion positioned inside the guide rail and a second portion positioned outside the guide rail, One aspect of this invention is to configure the capturing mechanism so that, during the process in which the lid member in the unfolded state transitions to the folded state and the process in which the lid member in the folded state transitions to the unfolded state, the guided portion abuts against the first portion, causing the second portion to retreat against the bias to a position where it does not come into contact with the decorative surface of the lid member, and in the unfolded state, the second portion advances by the bias to a position where it captures the captured portion. [Effects of the Invention]

[0010] The storage device according to the present invention includes the capture mechanism, release mechanism, biasing mechanism, and damper mechanism. Therefore, first, the capture mechanism can maintain the unfolded state of the lid member, i.e., the state in which the opening of the storage device main body is blocked. Second, the release mechanism can be operated to release the capture by the capture mechanism, thereby transitioning the lid member to a folded state and opening the opening of the storage device main body. This transition is achieved by the biasing force of the biasing means, and the braking force of the braking means is applied to this transition. Third, in the process of transitioning the lid member from the folded state to the unfolded state, the capture mechanism can be made to recapture the captured portion, thereby re-creating the state in which the opening of the storage device main body is blocked.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, exemplary embodiments of the present invention will be described with reference to FIGS. The storage device according to the present invention is typically installed in the interior of a vehicle such as a passenger car, and is used to store various items in a state where they can be easily taken out as needed. In the illustrated example, the storage device is configured to be suitable for use as a center console box in an automobile. 1, 9, and 10, the symbol x indicates a first direction, and the symbol y indicates a second direction perpendicular to the first direction. Typically, when the first direction x is the front-rear direction, the second direction y is the left-right direction, and when the first direction x is the left-right direction, the second direction y is the front-rear direction.

[0013] The storage device includes a storage device main body M and a lid member L.

[0014] (Storage device body M) The storage device body M has a rectangular opening 1 and a guide rail 2. In the illustrated example, the opening 1 is formed to have a rectangular outline that is long in the first direction x. In FIG. 1, reference numeral 3 denotes a base that is the upper part of the storage device main body M, and reference numeral 4 denotes a cover that is attached to the base 3. The base 3 is configured to be attached to the lower part of the storage device main body M (not shown) so that the opening 1 communicates with the inside of the lower part. On the upper surface of the base 3, wall portions 5 extending in the second direction y are formed on the left and right sides of the opening 1 in FIG. A receiving surface 6 for the lid member L is formed between the wall portion 5 and the edge of the opening 1 along the second direction y of the opening 1.

[0015] In the illustrated example, the guide rail 2 is formed on the wall 5 on the left side in FIG. 9. The guide rail 2 is formed on an inner surface 5a of the wall 5 that intersects at a right angle with the receiving surface 6. The guide rail 2 is a groove with a bottom, and is formed so as to extend over the entire length of the wall 5. Two groove ends 2a of the guide rail 2 are each closed.

[0016] In the illustrated example, the wall portion 5 is configured by combining a lower constituent body 5b and an upper constituent body 5c in FIG. 15 so as to form a guide rail 2 therebetween. In the illustrated example, an auxiliary guide rail 7 is formed on the wall 5 on the right side in Fig. 9. The auxiliary guide rail 7 is also formed on the inner surface 5a of the wall 5 that intersects with the receiving surface 6 at a right angle. The auxiliary guide rail 7 is also in the form of a groove with a bottom, and is formed to extend over the entire length of the wall 5. A first holding portion 7a and a second holding portion 7b, which will be described later, are formed at two groove ends of the auxiliary guide rail 7. In the illustrated example, the guide rail 2 and the auxiliary guide rail 7 are formed at substantially the same level. Furthermore, both the guide rail 2 and the auxiliary guide rail 7 are formed so as to follow an imaginary arc with the upper side curved outward.

[0017] In the illustrated example, the receiving surface 6 near the wall portion 5 where the guide rail 2 is formed and the receiving surface 6 near the wall portion 5 where the auxiliary guide rail 7 is formed each have a recess 6a formed at a position about midway in the second direction y for receiving a lower portion of a first bearing portion 19 (described below) of the lid member L in the unfolded state. This prevents the lid member L, which is in the unfolded state and covers the opening 1 of the storage device main body M, from rattling in the second direction y.

[0018] The storage device main body M further includes a capture mechanism 8 and a release mechanism 9, which will be described later. In the illustrated example, the main parts of these mechanisms are housed in the wall 5 on the left side in FIG. 9. In the figure, reference numeral 9a denotes an operation button that constitutes the release mechanism 9, and reference numeral 4a denotes a hole formed in the cover 4 that allows the operation button 9a to face the outside of the cover 4.

[0019] (Lid component L) The lid member L closes the opening 1 in the unfolded state (FIG. 1), and has a guided portion 13 for the guide rail 2 on a first side portion 10 facing the guide rail 2.

[0020] In the illustrated example, the lid member L is in the shape of a rectangular plate that, in the unfolded state, closes the opening 1. The lid member L also has an auxiliary guided portion 14 for the auxiliary guide rail 7 on a second side portion 11 opposite to the first side portion 10. The first side portion 10 and the second side portion 11 are side portions that constitute the thickness of the lid member L and are located between the front and back surfaces of the lid member L. The lid member L also has two third side portions 12 that are aligned along the first direction x and perpendicular to both the first side portion 10 and the second side portion 11. The guided portion 13 is composed of boss-shaped bodies formed to protrude from the first side portion 10 in the first direction x at each of the two corners where the first side portion 10 intersects with the third side portion 12. In addition, the auxiliary guided portion 14 is composed of a boss-shaped body formed to protrude from the second side portion 11 along the first direction x at each of the two corners where the second side portion 11 intersects with the third side portion 12.

[0021] The lid member L is formed by connecting two or more lid components 15, each having the guided portion 13, via an axis 16, and is configured so that in the unfolded state, each lid component 15 is positioned flush to close the opening 1, and in the folded state by bending around the axis 16, the opening 1 is opened. In FIG. 17, reference numeral 17 denotes a base of the lid structure 15, and reference numeral 18 denotes a cover that is attached to the base 3 and forms the design surface of the lid structure 15. In the illustrated example, the lid member L is made up of two lid components 15. In one of the two lid structures 15 Lid member L In the unfolded state, a first bearing portion 19 is formed on the side portion located in the middle in the second direction y, and the other of the two lid components 15 is Lid member L A second bearing portion 20 is formed on a side portion positioned in the middle in the second direction y in the unfolded state.

[0022] The lid structure 15 located on the lower side in Fig. 17 has three first bearing portions 19 formed therein with a gap between adjacent bearing portions in the first direction x. The lid structure 15 located on the upper side in Fig. 17 has a plurality of second bearing portions 20 formed therein with a gap between them in the first direction x.

[0023] The two lid components 15 are combined with one of the first bearing portions 19, with the other second bearing portion 20 housed between the other first bearing portion 19, so that the second bearing portion 20 can rotate around the shaft body 16 fixed to the first bearing portion 19. In the illustrated example, the two lid components 15 are combined with three shaft bodies 16 whose shaft center lines are positioned on one imaginary straight line S1 (FIGS. 1, 9, and 17).

[0024] Each of the two lid components 15 is formed with one guided portion 13 and one auxiliary guided portion 14. The two lid components 15 combined by the shaft body 16 are combined with the storage device main body M in a state in which the transition from the unfolded state (FIG. 1) to the folded state (FIG. 3) (the transition in the order of FIGS. 1, 2, and 3) and the transition from the folded state (FIG. 3) to the unfolded state (FIG. 1) (the transition in the order of FIGS. 3, 2, and 1) can be regularly realized by fitting the guided portion 13 into the groove-shaped guide rail 2 and fitting the auxiliary guided portion 14 into the groove-shaped auxiliary guide rail 7.

[0025] The lid member L is also provided with a biasing mechanism 21 that biases the lid structure 15 so as to transition the lid member L to the folded state when the capture by the capture mechanism 8 described below is released, and a damper mechanism 22 that brakes the movement of the lid structure 15 due to the biasing of the biasing mechanism 21, i.e., the transition movement of the lid member L.

[0026] In the illustrated example, the biasing mechanism 21 is configured by a torsion coil spring 21a that is wound around the outside of the shaft body 16 between the first bearing portion 19 located on the left side in Fig. 19 and the intermediate first bearing portion 19. One end of the torsion coil spring 21a is fixed to the second bearing portion 20, and the other end of the torsion coil spring 21a is fixed to the first bearing portion 19 located on the left side in Fig. 19. In the illustrated example, when the lid member L is released from the capture by the capture mechanism 8 described below, the lid member L, which is in an unfolded state, is biased by the torsion coil spring 21a to transition from an unfolded state in which the inner surfaces of the two lid constituent bodies 15 are positioned on a single imaginary plane to a folded state in which the inner surfaces face each other.

[0027] In the illustrated example, the damper mechanism 22 is configured with a rotary damper 22a built in between the first bearing portion 19 located on the right side in FIG. 19 and the intermediate first bearing portion 19. In the illustrated example, two rotary dampers 22a are built in. The rotary damper 22a has an inner cylinder 22c rotatably housed within an outer cylinder 22b and is configured to apply a constant damping force to the rotation of the inner cylinder 22c. In the illustrated example, a viscous fluid such as silicone oil is sealed between the outer cylinder 22b and the inner cylinder 22c, thereby applying a constant damping force to the rotation of the inner cylinder 22c. The outer cylinder 22b of the rotary damper 22a is fixed to one end of the shaft 16, while the other end of the shaft 16 is fixed to the first bearing portion 19. The inner cylinder 22c is fixed to the lid structure 15 on which the second bearing portion 20 is formed. This applies a certain braking force to the rotation or relative rotation of the second bearing portion 20 around the shaft body 16. Therefore, the transition of the lid member L from the unfolded state to the folded state by the biasing mechanism 21 can be made gradual, giving the viewer a sense of moderation and luxury.

[0028] (Capturing mechanism 8) The storage device main body M is provided with a capturing mechanism 8 that captures the captured portion 23 formed on the first side portion 10 of the lid member L in the unfolded state. When the lid member L is unfolded, the guided portions 13 are positioned at the two groove ends 2a of the guide rail 2, and the auxiliary guided portions 14 are positioned at the two groove ends of the auxiliary guide rail 7 (see Figure 9). By capturing the captured part 23 by the capturing mechanism 8, the opened state of the lid member L, that is, the state in which the opening 1 of the storage device main body M is closed, is maintained. The capture of the captured portion 23 by the capture mechanism 8 can be released by operating the release mechanism 9 described below, and when this capture is released, the lid member L is guided by the guide rail 2 and the auxiliary guide rail 7 by the force of the biasing mechanism 21, and transitions to a folded state.

[0029] In this embodiment, the capturing mechanism 8 comprises a first portion 8 a positioned inside the guide rail 2 and a second portion 8 b positioned outside the guide rail 2 .

[0030] In the illustrated example, a first penetration portion 24 is formed in the storage device main body M at a position midway in the second direction y so as to penetrate the groove bottom forming portion 2b (see Figures 10 and 15) of the guide rail 2 in the first direction x. Further, a second penetration portion 25 is formed in the wall portion 5 of the storage device main body M at a position directly below the first penetration portion 24 so as to penetrate the wall portion 5 in the first direction x. The capture mechanism 8 comprises the first part 8a, the second part 8b located below the first part 8a, and a third part 8c located between the first part 8a and extending in the vertical direction to integrate the two parts. The capturing mechanism 8 is built into the wall portion 5 so that the first portion 8a is positioned within the guide rail 2 through the first through-hole 24, and the second portion 8b can be protruded from the wall portion 5 through the second through-hole 25 to the right side in Figure 20, which is the side of the opening 1. The capture mechanism 8 is supported on the wall portion 5 so as to be movable in the first direction x within a certain range.

[0031] The capturing mechanism 8 also includes a biasing means that causes the first portion 8a to protrude most from the first through-hole 24 and the second portion 8b to protrude from the wall portion 5 through the second through-hole 25 to a reference position (FIG. 20) where the capturing mechanism 8 is movable from this reference position toward the left in FIG. 20. In the illustrated example, the biasing means is a torsion coil spring 8d (FIGS. 10 and 15) built into the wall portion 5.

[0032] On the other hand, in this embodiment, the captured portion 23 is a recess formed in the first side portion 10 of the lid member L. In the illustrated example, the captured part 23 has a groove shape that continues in the second direction y when the lid member L is in the deployed state. The second part 8b of the capturing mechanism 8 has a cross-sectional shape that matches the captured part 23 and is configured to enter the captured part 23 at the reference position. When the lid member L is in the deployed state, the second portion 8b of the capturing mechanism 8 in the reference position enters into the captured portion 23. As a result, first, the unfolded state of the lid member L, i.e., the state in which the opening 1 of the storage device main body M is blocked, can be maintained. Second, by moving the capturing mechanism 8 against the biasing force of the biasing means so that the second portion 8b of the capturing mechanism 8 comes out of the captured portion 23, the capture can be released, the lid member L can be transitioned to a folded state, and the opening 1 of the storage device main body M can be opened. Third, in the process of transitioning the lid member L from the folded state to the unfolded state, a part of the lid member L abuts against the second portion 8b of the capturing mechanism 8, which has been repositioned to the reference position by the biasing means (torsion coil spring 8d), causing the capturing mechanism 8 to retreat against the biasing force, allowing the lid member L to transition to the unfolded state. Furthermore, when the lid member L is in the unfolded state, the capturing mechanism 8 can be returned to the reference position by the biasing force, causing the second portion 8b of the capturing mechanism 8 to re-enter the captured portion 23. This makes it possible to recreate the state in which the opening 1 of the storage device main body M is blocked.

[0033] In the illustrated example, the second part 8b of the capture mechanism 8 has an inclined upper surface 8e so that the thickness of the second part 8b gradually decreases as it approaches its protruding end (see Figure 8), and this inclination of the upper surface 8e allows the capture mechanism 8, which is in the reference position, to smoothly retreat when a part of the lid member L abuts against the second part 8b of the capture mechanism 8 as described above.

[0034] In the illustrated example, the captured portion 23 is formed at a position that is the center of the mountain fold of the lid member L in the folded state (see FIG. 2). However, it is sufficient that the captured portion 23 is located on the first side portion 10 of the lid member L. Although not shown in the drawings, the captured portion 23 may also be formed at a position that is between the center of the mountain fold of the lid member L in the folded state and the guided portion 13. In the illustrated example, when the lid member L is folded, the position where the pair of lid structures 15 are joined by the shaft 16 is the center of the mountain fold, and this center is positioned above the opening 1, thereby opening the opening 1. The captured portion 23 is formed at a position that is approximately midway in the second direction y on the first side portion 10 of the lid member L.

[0035] Specifically, the captured portion 23 is formed at the end portion that constitutes the first side portion 10 of the first bearing portion 19. The captured portion 23 configured in this manner is positioned on a virtual straight line S1 on which the axial center line of the shaft body 16 is located. By providing the captured portion 23 at such a position, when the lid member L is in the unfolded state, it is possible to prevent as much as possible the situation where the position that is the center of the mountain fold in the lid member L, i.e., the position where the two lid components 15 are joined by the shaft 16, is slightly lifted up by the action of the biasing mechanism 21 and separated from the receiving surface 6. Although not shown in the figures, the captured portion 23 can also be provided at a position where the distance between the guided portion 13 in one lid component 15 and the position that is the center of the mountain fold is smaller than the distance from the guided portion 13, thereby achieving a similar effect of preventing lifting up.

[0036] In the illustrated example, in the process of the lid member L in the unfolded state transitioning to the folded state and in the process of the lid member L in the folded state transitioning to the unfolded state, the capturing mechanism 8 is retracted against the biasing force to a position where the second portion 8b does not come into contact with the design surface of the lid member L due to the contact of the guided portion 13 with the first portion 8a. At the same time, the capturing mechanism 8 is configured to be advanced by the biasing force to a position where the second portion 8b captures the captured portion 23 in the unfolded state.

[0037] In the illustrated example, the first portion 8a of the capturing mechanism 8 has a trapezoidal plate shape in a plan view, with its length in the second direction y and its width in the first direction x. The width of the first portion 8a is set so that the capturing mechanism 8 does not protrude from inside the guide rail 2 when it is in the reference position.

[0038] Specifically, the first portion 8a has a top side 8f along the second direction y and a bottom side 8g along the second direction y that is longer than the top side 8f. The first portion 8a also has inclined sides 8h on both sides of the top side 8f that gradually increase the dimension of the first portion 8a in the second direction y as they approach the bottom side 8g. In the reference position, the first portion 8a is configured so that the bottom side 8g is flush with the groove bottom-forming portion 2b of the guide rail 2, and the top side 8f is flush with the groove opening 2c of the guide rail 2 (see FIG. 10).

[0039] In both the process in which the lid member L in the unfolded state transitions to the folded state and the process in which the lid member L in the folded state transitions to the unfolded state, in the illustrated example, one of the two guided portions 13 moves along the guide rail 2, but when the guided portion 13 reaches a position about halfway in the second direction y, it comes into contact with the inclined edge 8h of the capturing mechanism 8, and the inclination of this inclined edge 8h causes the capturing mechanism 8 to move in a direction against the biasing force of the biasing means, and accordingly the second portion 8b also moves, causing the portion protruding from the second through portion 25 to be retracted into the wall portion 5 (FIG. 12). As a result, in both the process in which the lid member L in the unfolded state transitions to the folded state and the process in which the lid member L in the folded state transitions to the unfolded state, the design surface formed by the cover 18 in the vicinity of the guided portion 13 moving along the guide rail 2 is not damaged by contact with the second portion 8b.

[0040] (Release mechanism 9) The storage device main body M is also provided with a release mechanism 9 that releases the captured portion 23 from the capturing mechanism 8 by operation.

[0041] In the illustrated example, the release mechanism 9 is composed of an operation button 9a which also forms part of the first operation mechanism 32 and second operation mechanism 33 described below, and a linkage rod 9b connected to this operation button 9a.

[0042] In the illustrated example, the release mechanisms 9 are provided on both sides of an imaginary straight line S1 that passes through the middle of the lid member L in the second direction y when in the unfolded state. The release mechanism 9 on one side of the straight line S1 is configured to be symmetrical to the release mechanism 9 on the other side of the straight line S1, so the following will describe the upper release mechanism 9 in Figure 10, and a description of the lower release mechanism 9 in Figure 10 will be omitted.

[0043] The operation button 9a is supported on the storage device main body M so as to be movable in the second direction y. It is also biased by a compression coil spring 9c (see FIG. 16) serving as a biasing means, and can be pushed in a direction approaching the straight line S1 against this bias, and when this pushing operation is stopped, the bias causes the operation button 9a to return to the position it was in before the pushing operation. A part of the operation button 9a is exposed to the side of the storage device main body M along the first direction x through a hole 4a formed in the side of the cover 4.

[0044] The linkage rod 9b is built into and supported by the wall 5 of the storage device main body M so as to be movable in the second direction y. The linkage rod 9b has a first cam surface 9d at an end located near the imaginary straight line S1 and a second cam surface 9e at the opposite end. The linkage rod 9b also has an arm 9e between both ends that protrudes in the first direction x. The arm 9e protrudes from the wall 5 toward the left in FIG. 10.

[0045] The second cam surface 9e of the linkage rod 9b is always in contact with a slider 30 formed on a first engagement portion 26, which will be described later. The first engagement portion 26, which will be described later, is built into the wall portion 5 so as to be movable in the first direction x, and is biased by a torsion coil spring 31 so as to position a claw portion 28, which will be described later, within the guide rail 2. This bias causes the slider 30 to always be in contact with the second cam surface 9e of the linkage rod 9b. The linkage rod 9b is positioned at a reference position (FIG. 10) by the bias of the torsion coil spring 28, which acts via the slider 30 in contact with the second cam surface 9e.

[0046] On the other hand, the first cam surface 9d of the linkage rod 9b is capable of coming into contact with the third portion 8c of the capturing mechanism 8.

[0047] When the operation button 9a is pressed, a part of the operation button 9a pushes the arm 9e of the linkage rod 9b in a direction approaching the imaginary straight line S1. As a result, the linkage rod 9b, which is in the reference position, moves in a direction approaching the imaginary straight line S1 (FIGS. 10 and 11). This movement causes the first cam surface 9d of the linkage rod 9b to press the third part 8c of the capturing mechanism 8, and the capturing mechanism 8 is moved in a direction to retract the part of its second part 8b that protruded from the second through-hole 25 into the wall part 5. In other words, pressing the operation button 9a that constitutes the first operating mechanism 32 described below releases the captured part 23 from the capturing mechanism 8. After this, when the pressing of the operation button 9a is stopped, the linkage rod 9b, which brings the slider 30 into contact with the second cam surface 9e, returns to its reference position due to the force of the torsion coil spring 31, and the capture mechanism 8, whose third part 8c has been released from pressure by the first cam surface 9d, also returns to its reference position, and the operation button 9a also returns to the position it was in before the pressing operation.

[0048] (First engagement portion 26, second engagement portion 27) The lid member L is provided with the guided portions 13 on both sides of the first side portion 10 sandwiching the shaft body 16, that is, on both sides of the imaginary straight line S1 sandwiching the shaft body 16. On the other hand, the storage device main body M is provided with a first engagement portion 26 that engages with the guided portion 13 located on one side of the shaft body 16 when the lid member L is in the unfolded state, and a second engagement portion 27 that engages with the guided portion 13 located on the other side of the shaft body 16.

[0049] In the illustrated example, a first engagement portion 26 is provided on one side of the virtual straight line S1 and a second engagement portion 27 is provided on the other side, and the second engagement portion 27 is configured to be linearly symmetrical to the first engagement portion 26 across this virtual straight line S1. Therefore, in the following, only the first engagement portion 26 on the upper side in Figure 10 will be described, and a description of the second engagement portion 27 on the lower side in Figure 10 will be omitted.

[0050] The first engagement portion 26 is built into the wall portion 5 so as to be movable in the first direction x. The first engagement portion 26 includes a claw portion 28 that can protrude into the guide rail 2 through a third through-hole 36 formed in the groove bottom forming portion 2b of the guide rail 2, with a gap between it and the groove end 2a of the guide rail 2 that allows the guided portion 13 to be held, and a base 29. The base 29 is formed with a slider 30 that has a protruding shape that protrudes in the vertical direction. The first engagement portion 26 is configured to be positioned at a reference position that positions the claw portion 28 within the guide rail 2 by the biasing force of a torsion coil spring 31 that serves as biasing means.

[0051] In the illustrated example, the claw portion 28 has a side portion 28a facing the imaginary straight line S1 that is inclined in a direction that gradually reduces the dimension of the claw portion 28 in the second direction y as it moves away from the imaginary straight line S1, and when the guided portion 13 is moved from the imaginary straight line S1 side, the side portion 28a abuts against the guided portion 13, causing it to move from the reference position to the left side in Figure 10 against the biasing force, allowing the guided portion 13 to move to the groove end 2a of the guide rail 2, and after the guided portion 13 has moved to this groove end 2a, it moves again to the reference position due to the biasing force and engages with the guided portion 13.

[0052] (First operating mechanism 32, second operating mechanism 33) In addition, the storage device main body M is provided with a first operating mechanism 32 that enables the first engagement portion 26 to be released from the engagement, and a second operating mechanism 33 that enables the second engagement portion 27 to be released from the engagement. When the engagement of the first engagement portion 26 is released by operating the first operating mechanism 32, the capture by the capture mechanism 8 is released while the engagement of the second engagement portion 27 is maintained, and when the engagement of the second engagement portion 27 is released by operating the second operating mechanism 33, the capture by the capture mechanism 8 is released while the engagement of the first engagement portion 26 is maintained.

[0053] In the illustrated example, a first operating mechanism 32 is provided on one side of the virtual straight line S1, and a second operating mechanism 33 is provided on the other side, and the second operating mechanism 33 is configured to be linearly symmetrical to the first operating mechanism 32 across this virtual straight line S1. Therefore, in the following, only the first operating mechanism 32 on the upper side in Figure 10 will be described, and a description of the second operating mechanism 33 on the lower side in Figure 10 will be omitted. In the illustrated example, the first operating mechanism 32 is made up of the operating button 9a and the linkage rod 9b.

[0054] When the operation button 9a of the first operation mechanism 32 is pressed while the lid member L is in the unfolded state, the linkage rod 9b is moved in a direction approaching the imaginary straight line S1, and the position at which the second cam surface 9e contacts the slider 30 of the first engagement portion 26 changes. As a result, the first engagement portion 26 is moved to the left in FIG. 10 from the reference position, and the claw portion 28 thereof comes out of the guide rail 2, thereby releasing the engagement state of the claw portion 28 with the guided portion 13 (FIGS. 11 and 12). On the other hand, the engagement of the second engagement portion 27 with the guided portion 13 will not be released unless the operation button 9a of the second operation mechanism 33 is pressed. At the same time, the linkage rod 9b moves in a direction approaching the virtual straight line S1, and the capturing mechanism 8 moves from the reference position as described above, and the captured part 23 is released. This allows the guided portion 13, which has been engaged with the first engaging portion 26, to move within the guide rail 2 while maintaining the engagement of the engaged portion by the second engaging portion 27. The lid member L is shifted to a bent state by the biasing force of the biasing mechanism 21, and the opening 1 of the storage device main body M can be gradually opened from the upper side in Figure 10 (Figures 2 to 3, Figures 12 to 13).

[0055] Conversely, when the operation button 9a of the second operation mechanism 33 is pressed while the lid member L is in the unfolded state, the linkage rod 9b is moved in a direction approaching the imaginary straight line S1, and the position at which the second cam surface 9e contacts the slider 30 of the second engagement portion 27 changes. As a result, the second engagement portion 27 is moved from the reference position to the left in Figure 10, and the claw portion 28 thereof comes out of the guide rail 2, thereby releasing the engagement state in which the claw portion 28 is engaged with the guided portion 13. On the other hand, unless the operation button 9a of the first operation mechanism 32 is pressed, the engagement of the first engagement portion 26 with the guided portion 13 is not released. At the same time, the linkage rod 9b moves in a direction approaching the virtual straight line S1, and the capturing mechanism 8 moves from the reference position as described above, and the captured part 23 is released. This allows the guided portion 13, which has been engaged with the second engaging portion 27, to move within the guide rail 2 while maintaining the engagement of the engaged portion by the first engaging portion 26. The lid member L is shifted to a bent state by the biasing force of the biasing mechanism 21, and the opening 1 of the storage device main body M can be gradually opened from the bottom side in Fig. 10 (Figs. 6 to 7).

[0056] (Auxiliary guided part 14) In addition, the lid member L has auxiliary guided portions 14 located on both sides of the shaft 16 at the second side portion 11 located opposite the first side portion 10, and the auxiliary guided portions 14 are positioned on a virtual straight line S2 passing through the guided portions 13.

[0057] In the illustrated example, the auxiliary guided portion 14 formed at one of the two corners where the second side portion 11 and the third side portion 12 meet is located on an imaginary straight line S2 along the first direction x that passes through the guided portion 13 formed at one of the two corners where the first side portion 10 and the third side portion 12 meet, and the auxiliary guided portion 14 formed at the other of the two corners where the second side portion 11 and the third side portion 12 meet is located on an imaginary straight line S2 along the first direction x that passes through the guided portion 13 formed at the other of the two corners where the first side portion 10 and the third side portion 12 meet (Figure 9). On the other hand, the storage device main body M is provided with a first holding portion 7a that houses the auxiliary guided portion 14 that is positioned on one side of the shaft body 16 in the unfolded state, a second holding portion 7b that houses the auxiliary guided portion 14 that is positioned on the other side of the shaft body 16 in the unfolded state, and an auxiliary guide rail 7 for the auxiliary guided portion 14 that spans between the first holding portion 7a and the second holding portion 7b. When the engagement of the first engagement portion 26 is released by operating the first operating mechanism 32, the auxiliary guided portion 14 housed in the first holding portion 7a enters the auxiliary guide rail 7, allowing the lid structure 15 to move toward the folded state, and the auxiliary guided portion 14 housed in the second holding portion 7b is held within the second holding portion 7b. On the other hand, when the engagement of the second engagement portion 27 is released by operating the second operating mechanism 33, the auxiliary guided portion 14 housed in the second holding portion 7b enters the auxiliary guide rail 7, allowing the lid structure 15 to move toward the folded state, and the auxiliary guided portion 14 housed in the first holding portion 7a is held within the first holding portion 7a.

[0058] As a result, the transition of the lid member L between the unfolded state and the folded state can be smoothly achieved by the guided portions 13 and the guide rail 2 at two locations, and the auxiliary guided portions 14 and the auxiliary guide rail 7 at two locations. That is, when the lid member L transitions from the unfolded state to the folded state, the auxiliary guided portions 14 that are fixed to the storage device main body M relative to the auxiliary guided portions 14 that are movable and enter the auxiliary guide rail 7 to be guided are held by the first holding portion 7a or the second holding portion 7b, and are held in a desired position together with the guided portions 13 that are fixed to the storage device main body M, and do not enter the auxiliary guide rail 7. As a result, tilting of the lid member L that would cause the virtual straight line S2 to not coincide with the first direction x during the transition of the lid member L is prevented, thereby ensuring the smooth transition of the lid member L.

[0059] In the illustrated example, the auxiliary guided portion 14 is axially shaped and is supported movably in the first direction x by a hole 34 that has a hole opening in the second side portion 11 of the lid member L and extends in a direction along the first direction x. The auxiliary guided portion 14 has a portion positioned outside the hole 34 and a portion positioned inside the hole 34. In addition, the auxiliary guided portion 14 is always subjected to a biasing force in a direction that causes it to protrude from the second side portion 11 by a compression coil spring 35 that serves as a biasing means housed inside the hole 34. The portion of the auxiliary guided portion 14 positioned outside the hole 34 has a protrusion 14b at an end 14a perpendicular to the central axis z (FIG. 26) of the auxiliary guided portion 14.

[0060] On the other hand, the first holding portion 7a and the second holding portion 7b have recesses 7c into which the protrusions 14b of the auxiliary guided portion 14 fit (FIGS. 24 and 25). They also have support surfaces 7d adjacent to the recesses 7c that are flush with the groove bottom of the auxiliary guide rail 7. They also have inclined surfaces 7e between the recesses 7c and the support surfaces 7d. In the illustrated example, the first holding portion 7a and the second holding portion 7b have support surfaces 7d at two locations spaced apart in the circumferential direction around the center of the recess 7c, and have inclined surfaces 7e adjacent to the two support surfaces 7d, respectively. The protrusion 14b has a central portion 14c that fits into the center of the recess 7c and peripheral portions 14d that correspond to and come into contact with the two support surfaces 7d. The contours of the protrusion 14b and the contours of the recess 7c are complementary to each other. When the lid member L is in an unfolded state and blocks the opening 1 of the storage device main body M, the auxiliary guided portion 14 is positioned at the formation position of the first holding portion 7a or the second holding portion 7b, but the peripheral portion 14d of the convex portion 14b is in contact with the support surface 7d so that the convex portion 14b is in a reference position (Figure 28) that does not allow the convex portion 14b to enter the concave portion 7c. When the engagement of the first engaging portion 26 is released, the auxiliary guided portion 14 located on the imaginary straight line S2 passing through the guided portion 13 engaged with the first engaging portion 26 enters the auxiliary guide rail 7, and the lid member L begins to transition to the folded state. At this time, the auxiliary guided portion 14 located on the imaginary straight line S2 passing through the guided portion 13 engaged with the second engaging portion 27 rotates at the formation position of the second holding portion 7b in accordance with the rotation of the lid structure 15 based on the transition of the lid member L toward the folded state. Then, with this rotation, the convex portion 14b gradually enters the concave portion 7b due to the biasing force (FIG. 29). This holds the auxiliary guided portion 14.

[0061] In addition, when the engagement of the second engagement portion 27 is released, the auxiliary guided portion 14, which is positioned on the virtual straight line S2 passing through the guided portion 13 engaged with the first engagement portion 26, is operated in the same manner.

[0062] When the lid member L in the folded state is returned to the unfolded state, the auxiliary guided portion 14 held as described above is gradually returned by the inclined surface 7e in a direction against the biasing force, and returns to the reference position in which the peripheral portion 14d of the convex portion 14b is in contact with the support surface 7d.

[0063] In the illustrated example, the lid member L is composed of two lid structures 15. 4In this case, the lid member L has an M-shape in the folded state, and there are two positions that are the centers of the mountain folds. too The guided part 13 and the auxiliary guided part 14 are It can be prepared.
