Description

  The present invention relates to a storage box that can open and close a lid.

  The center console of the vehicle is provided with a storage box that opens and closes the lid. Storage boxes include a single-open storage box that can be opened and closed only from one side on the left and right sides, and a double-open storage box that can open and close the lid from both sides.

  Conventionally, as the double storage box, as shown in FIGS. 2 and 9 of Patent Document 1, standing walls (1A, 1B) are provided on the front side and the rear side of the box body, and the standing walls (1A, 1B) are provided. The left and right hinge pins (26, 27) are fitted in shaft holes (3) formed on the left and right sides of the left and right sides of the shaft hole (3). For example, when the left pin pin (26, 27) is fitted into the shaft hole (3) and the right hinge pin (26, 27) is removed from the shaft hole (3), the lid (L) is centered on the left hinge pin. Rotates and the right side of the lid (L) opens.

  In the vehicle compartment disclosed in FIGS. 1 and 4 of Patent Document 2, the end face of the storage compartment cover (2) in the closed state is placed on the end face of the console (12) provided before and after the storage compartment (11). Oppositely, the rotating shaft (21, 22) provided on the end surface of the storage compartment cover (2) is fitted to a fitting portion formed on the end surface of the console (12) so as to be able to advance and retreat.

  In the center console box disclosed in FIGS. 2 and 6 of Patent Document 3, a link body (3) is interposed between the opening forming body (1) and the lid body (2) at the front portion and the rear portion thereof. is doing. The front and rear link bodies (3) are detachably connected to the lid body (2) at both left and right ends, and are detachably connected to the opening forming body (1) at the center. Yes. When the left side of the lid is opened in FIG. 6 of Patent Document 3, the left operating body (23) is operated to release the fitting with the lid body (2) at the left end of the rear link body (3). At the same time, the latch receiver (12) at the center of the front link body (3) is opened.

  However, in the above-described conventional storage box, there are the following as problems of both the single opening and the double opening.

  In Patent Document 1, it is necessary to prevent the lid from protruding greatly from the side wall of the box body so that the opened lid does not interfere with the driver's seat or the passenger seat. For this reason, it is necessary to arrange the hinge pin (26, 27) of the lid as an axis of rotation at the upper part of the lid and to arrange the shaft hole (3) for pivotally supporting the axis of rotation above the box body. For this reason, it is necessary to provide the recessed part for arrange | positioning a rotating shaft in the cushion part provided above the lid, and the thickness of the whole area of a cushion part cannot be made uniform.

  Moreover, in patent document 1, in order to make small the clearance gap between the outline of the side surface of a lid, and the upper surface of a box main body, you have to make the outline of the side surface of a lid, and a rotating shaft parallel. If the side profile of the lid and the rotation axis are not parallel, the gap between the side profile of the lid and the top surface of the box body must be increased, especially when the lid is closed. The gaps between them are visible, and the appearance is impaired. For this reason, the freedom degree of the design of the outline of the side surface of a lid will be restrict | limited.

  Moreover, in patent document 2, although there is no standing wall like patent document 1, the fitting mechanism with the storage compartment (11) is provided in the end surface of the storage compartment cover (2). For this reason, the thickness of the end face of the storage compartment cover (2) is increased, and the design is greatly restricted. Furthermore, for example, when it is intended to provide the storage compartment cover (2) with a tray that slides in the front-rear direction, the fitting mechanism provided on the end surface of the storage compartment cover (2) becomes an obstacle, which makes design difficult. There is sex.

  In Patent Document 4, the lid main body (32) is configured to be slidable in the front-rear direction, but the number of parts is large, and an increase in cost is inevitable.

  Next, in the above-described conventional storage box, there are the following problems as problems of double opening.

  In Patent Document 1, standing walls (1A, 1B) are erected from a box body, and a shaft hole (3) is formed in the standing walls (1A, 1B). However, the standing wall (1A, 1B) becomes an obstacle when the stored item is put in and out of the opening inside the box body. Also, it doesn't look good.

  In Patent Document 3, when the lid body (2) is opened, one of the front and rear link bodies (3) remains on the opening periphery of the opening forming body (1). For this reason, it becomes an obstacle at the time of putting in and out the stored matter inside the opening forming body (1), and it does not look good.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a storage box having a good appearance and a small number of parts without the side surface of the lid protruding from the side wall of the box body.

(1) A storage box according to the present invention includes a box body provided with a storage space having an opening in the upper part, a lid covering the opening, a left side of the lid and at least one of the left side and the right side of the lid as a rotation center And an opening / closing mechanism that opens and closes the other of the right side, wherein the opening / closing mechanism is provided on each of the front and rear sides in the front-rear direction orthogonal to the left-right direction of the lid, and constitutes the rotation center, A pair of lid-side rotation center portions located at a portion where the distance from the left and right side surfaces of the lid is larger than the distance from the lower surface of the lid, and the front side and the rear side of the opening in the box body A pair of main body side rotation center portions provided on the center side in the left-right direction with respect to the pair of lid side rotation center portions, respectively, and the pair of main body side rotation portions. A pair of link members disposed between the main body side rotation center portion and the lid side rotation center portion, each of which is disposed between the main body side rotation center portion and the lid side rotation center portion. In the closed state where the lid closes the opening, the lid-side rotation center portion is in a reference position, and the other of the left side and the right side of the lid opens the opening. In this case, the lid rotates about the lid side rotation center of one of the left side and the right side of the lid, and one side surface of the left side and the right side of the lid abuts on the upper surface of the box body. The link member rotates about the main body side rotation center portion, thereby moving the lid side rotation center portion upward from the position of the lid side rotation center portion in the closed state. Move to the center of the lid in the horizontal direction Characterized in that to.

  According to the above configuration, when the lid is in the closed state, the lower surface of the lid faces the upper surface of the box body. When the lid is changed from the closed state to the open state, the surface of the lid that faces the upper surface of the box body changes from the lower surface of the lid to the side surface of the lid.

  Here, the distance between the lid-side rotation center and one of the left and right side surfaces of the lid is larger than the distance between the lid-side rotation center and the lower surface of the lid. For this reason, when the lid is changed from the closed state to the open state, the side surface of the lid faces the upper surface of the box body, and the lid-side rotation center portion rises. The lid is supported by the link member at the lid side rotation center. When the lid-side rotation center is raised, the link member rotates about the main body-side rotation center, and the direction in which the lid-side rotation center is separated from the side surface of the box body, that is, the center in the left-right direction of the box body. Move towards the department. Therefore, in the lid open state, the lid is displaced to the inner side in the left-right direction of the box body than in the closed state. Therefore, the lid in the open state does not jump out greatly from the side surface of the box body.

  Further, since the distance between the lid-side rotation center portion and the lower surface of the lid is smaller than the distance between the lid-side rotation center portion and the side surface of the lid, the lid-side rotation center portion is the lower surface of the lid. Can be provided at a position close to. Therefore, it is not necessary to form a recessed portion for providing the lid side rotation center portion in the cushion portion covering the upper side of the lid. Therefore, the thickness of almost the entire area of the cushion portion can be made uniform.

  Further, when the storage box of the present invention is used as a console box that is disposed on the center console of a vehicle, a cushion member for an armrest of an occupant that is normally disposed on the upper surface of the lid is formed with a substantially uniform thickness in a plane. be able to. For this reason, the passenger | crew can mount an elbow comfortably on a cushion member.

  Further, when the slide mechanism is provided on the lid, the lid-side rotation center portion does not become an obstacle to the space for providing the slide mechanism.

  When the other of the left side and the right side of the lid is in the open state, one of the lid side rotation centers on the left side and the right side of the lid is raised. Therefore, it is not necessary to secure a gap for the rotation of the lid when the lid is in the closed state. Further, even when the lid side surface is not parallel to the lid side rotation center portion, when the lid is in the open state, the most swelled portion of the lid side surface abuts on the opening peripheral edge of the box body, and the lid side rotation center portion Rises. For this reason, a gap for rotating the lid is not required. Therefore, the degree of freedom in designing the lid is high.

  In addition, when the other of the left and right sides of the lid is in an open state, the vicinity of one of the left and right lid rotation center portions of the link member can be slightly seen between the box body, but the link member body side The vicinity of the center of rotation is arranged inside the box body and does not appear externally. Therefore, it looks good.

Further, since the lid and the box body are connected by a link member, the number of parts is small.
(2) The opening / closing mechanism is further provided along a rotating base that is rotatably provided on at least one of the wall portions on the front side and the rear side of the opening in the box body, and the rotation direction of the link member. A link-side gear formed on the peripheral surface, a pedestal-side gear formed on the peripheral surface of the rotating pedestal and meshing with the link-side gear, and an axially extending end surface of the rotating pedestal, extending in the radial direction Both ends of the rotary base are pivotally supported on the end face in the axial direction of the rotary base, and a rotating shaft having a pinion gear formed on the peripheral surface and a rack gear extending in a long shape and meshing with the pinion gear are formed in the extending direction. One end of the arm in the extending direction is rotatably supported by a portion of the lid located on the center side in the left-right direction relative to the lid-side rotation center. Arm is the lid The supported end is pivotable about the one end, and when the lid is opened and closed, the arm moves in the extending direction with respect to the rotating base by meshing the rack gear and the pinion gear, and the rotation angle of the lid The rotation angle of the arm changes due to the change of the arm, the change of the rotation angle of the arm is transmitted to the rotation shaft, the rotation shaft rotates together with the rotation base in the rotation direction of the arm, and the side of the base It is preferable that the rotation of the rotating base is transmitted to the link member by meshing the gear and the link side gear, and either the left side or the right side of the link member is raised.

In this case, when the lid is opened and closed, the arm moves in the extending direction due to the engagement of the rack gear and the pinion gear, and the arm rotates around its one end. Along with this, the rotating base that pivotally supports the rotating shaft having the pinion gear also rotates in the rotating direction of the arm. The link member rotates in a direction opposite to the rotation direction of the rotary base by meshing the base side gear and the link side gear. That is, the link member rotates in a direction opposite to the rotation direction of the arm, raises one end of the left side and the right side of the link member, and raises one lid side rotation center of the left side and the right side. As described above, the lid opening / closing locus is formed by a four-bar link structure including the lid, the arm, the link member, and the rotating base. Therefore, it is not necessary for the side surface of the lid and the opening peripheral edge of the box body to be in contact with each other during the opening and closing of the lid, and the lid can be opened and closed smoothly.
(3) The opening / closing mechanism further includes a check arm that is rotatably supported at a portion of which one end portion is positioned on the center side in the left-right direction with respect to the lid-side rotation center portion of the lid; A main body formed on at least one of the wall portions on the front side and the rear side of the opening, and having a shape along a movement trajectory in which the other end portion of the check arm moves relative to the box main body as the lid is opened and closed. A side guide groove, a link side guide groove formed on the link member, and having a shape along a movement locus in which the other end of the check arm moves with respect to the link member as the lid is opened and closed; Preferably, the other end of the check arm is movably fitted in the main body side guide groove and the link side guide groove.

In this case, the movement direction of the other end portion of the check arm is restricted by the main body side guide groove, and the movement direction of the link member with respect to the check arm is restricted by the other end portion of the check arm that moves in the link side guide groove. The Therefore, the moving direction of the link member with respect to the box body is restricted via the check arm. Therefore, the play of the link member itself is suppressed, and when the lid is closed, the link member is securely fitted to the lid side rotation center.
(4) The opening / closing mechanism can open and close both the left side and the right side of the lid, and the left and right sides of the lid are respectively provided with a pair of lid side rotation centers, and the pair of links The member has left and right fitting portions that are detachably supported by a pair of lid side rotation center portions respectively provided on the left and right sides of the lid, and the opening / closing mechanism is further operated by an operation. An operation portion is provided for detaching the fitting portion on either the left side or the right side from the lid side rotation center portion, and the pair of body side rotation center portions are centers in the left-right direction of the box body. And it is preferable to be located below a pair of said lid side rotation center part each provided in the left side and the right side of the said lid.

  In this case, the link member is detachably supported by the main body side rotation center portion at a position lower than the lid side rotation center portions on both the left and right sides. For this reason, when the lid is rotated about one of the left and right sides of the lid and the other is opened, the portion of the link member that rotates is raised together with the lid-side rotation center. Since the link member rotates about the rotation center portion on the main body side, the portion of the left and right sides where the lid opens is lowered. Therefore, since the link member does not protrude from the opening periphery of the box body on the open side of the lid, access when the stored item is taken in and out of the opening of the box body is not hindered by the link member. Further, the link member cannot be seen from the opening peripheral edge of the box body on the side where the lid is opened, and the appearance is good.

In addition, since the pair of link members are opened and closed on both the left and right sides, an increase in the number of components can be suppressed, and the double-opening storage box can have a simple configuration.
(5) It is preferable that the rotating pedestal is disposed at the center in the left-right direction of the box body, and one end portion in the extending direction of the arm is rotatably supported at the center in the left-right direction of the lid. .

In this case, the movement of the link member is supported by the four-bar linkage mechanism between the lid, the arm, the link member, and the rotating base when the lid opens and closes to the left and right. Therefore, the wear on the side surface of the lid can be suppressed, and the right and left sides of the lid can be smoothly opened and closed. Furthermore, an increase in the number of parts can also be suppressed.
(6) On the front and rear peripheral edges of the opening of the box body, a left hole for moving the left end of the link member forward and backward and a right hole for moving the right end of the link member forward and backward, respectively. The left end and the right end of the link member are flush with the periphery of the other hole on the left and right sides of the lid when the other of the left and right sides of the lid is opened. It is preferable to have a closed surface.

In this case, when the other of the left and right sides of the lid is opened, the other left and right hole portions formed in the box body are connected to the periphery of the hole portion by the other of the left and right end portions of the link member. It is closed in the same plane. Therefore, the appearance of the peripheral edge of the opening of the box body is good. Further, there is no possibility that foreign matter will fall from the hole into the box body.
(7) It is preferable that the said arm and the said rotation base are arrange | positioned in the direction close | similar to the said operation part among the front side and the rear side of the said box main body.

  In this case, even if a load is applied to the lid by the operation of the operation unit, the moment applied to the arm or the rotation pedestal can be increased by arranging the arm and the rotation pedestal closer to the operation unit between the front side and the rear side. Can be small. Moreover, the twist of a lid can also be suppressed.

  (8) The one end portion of the check arm is rotatably supported at a central portion in the left-right direction of the lid, and the main body side guide groove and the link side guide groove are respectively formed on the check arm. It is preferable that the other end portion is bifurcated in a bilaterally symmetrical shape on both sides in the left-right direction of the wall portion of the box body, with the portion positioned at the lowermost end as a center.

In this case, the moving direction of the link member relative to the box body is regulated via the check arm when either the left or right side of the lid is opened or closed. Therefore, the lid side rotation center portion is securely fitted to the link member when either the left or right side of the lid is closed.
(9) The opening / closing mechanism is further disposed in the main body side rotation center portion that rotatably supports the link member, and restricts rotation of the link member with respect to the main body side rotation center portion. It is preferable that a biasing means for biasing in the direction is provided.
In this case, since the urging means is disposed in the main body side rotation center part away from the lid side rotation center part, compared with the case where the urging means is provided in the lid side rotation center part, The rotational moment necessary to regulate the lid rotation is reduced. Therefore, the urging force of the urging means necessary to maintain the lid closed state may be small.
(10) It is preferable that the opening / closing mechanism further includes an urging unit that is disposed on the rotating shaft and restricts movement of the pinion gear formed on the rotating shaft with respect to the rack gear.
Also in this case, since the rotation shaft on which the urging means is disposed is disposed at the main body side rotation center part away from the lid side rotation center part, the urging means is provided at the lid side rotation center part. As compared with the case where the lid is provided, the rotational moment necessary for restricting the rotation of the lid is reduced. Therefore, the urging force of the urging means necessary for maintaining the lid in the closed state may be small.

  According to the storage box of the present invention, since the lid-side rotation center portion is arranged at a position closer to the lower surface than the side surface of the lid, the lid side surface abuts on the upper surface of the box body and the lid-side rotation center portion. To raise. For this reason, the side surface of the lid does not protrude greatly from the side surface of the box body, the appearance is good, and the number of parts can be reduced.

The lid side rotation center portion 35b provided on the left side of the lid 3 is formed in the same structure at a position symmetrical to the left lid side rotation center portion 35a in the left-right direction.

  As shown in FIG. 7, the main body side rotation center portion 25 is provided at the lower part of the front and rear peripheral edge portions 23 on both the front side and the rear side of the box main body 2. On the lower surface of the front and rear peripheral edge 23, a fixed wall 23a projects downward. The fixed wall 23 a faces the front and rear walls 24 that surround the front of the storage space 20. A main body side rotation center portion 25 that protrudes toward the front and rear walls 24 is provided at a portion of the fixed wall 23a located in the center in the left-right direction. The main body side rotation center portion 25 is inserted into a central shaft hole 41e formed in the upper portion of the center portion 41a of the link member 41, and always supports the link member 41 so as to be rotatable. The tip of the main body side rotation center portion 25 is locked to a step portion 24 b formed on the front and rear walls 24.

  The link member 41 is disposed in a gap between the front and rear walls 24 of the box body 2 and the fixed wall 23a. As shown in FIGS. 4 and 6, the link member 41 is a thin plate member having the shape of an upper pan balance. Specifically, the link member 41 includes a central portion 41a that is vertically long, an arm portion 41b that extends from the central portion 41a to the left and right sides, a bent portion 41c that is bent upward from the tip of the arm portion 41b, and a bent portion 41c. It has a tip 41d extending outward in the left-right direction at the upper end, and has a symmetrical shape with respect to the center 41a as the center.

  The upper edge portion 41f of the link member 41 is made thicker than other portions in order to improve rigidity. When the lid is closed, the distal end portions 41d on both the left and right sides of the link member 41 pass through the gaps between the front and rear walls 24 and the fixed wall 23a and through the hole portions 23b formed on the left and right sides of the front and rear peripheral edge portions 23. Projecting upward.

  Front end shaft holes 41g and 41h are formed in the right and left front end portions 41d of the link member 41. The tip shaft holes 41g and 41h correspond to the fitting portions of the present invention. The distal end shaft holes 41g and 41h are rotatably and detachably fitted to the lid side rotation center portions 35a and 35b. The front end 41d is accommodated in a recess 31f formed in the lower surface 31e of the base 31 of the lid 3 when the lid is closed, and is supported by the lid-side rotation center portions 35a and 35b. When the lid is opened, the distal end portion 41 d of the link member 41 is detached from the lid side rotation center portions 35 a and 35 b and retreats into the hole portion 23 b formed in the front and rear peripheral edge portion 23 of the box body 2. As shown in FIG. 1, when the lid is fully opened, the back surface 41i of the tip end portion 41d forms the same surface as the front and rear peripheral edge portion 23 and becomes a closed surface that closes the hole portion 23b.

  As shown in FIG. 6, the spring 42 has a winding portion 42 a that is wound and stores a spring force, and end portions 42 b and 42 c that extend from the winding portion 42 a. The winding portion 42 a of the spring 42 is wound around the main body side rotation center portion 25. The end portions 42 b and 42 c of the spring 42 include a movable locking portion 41 j that protrudes toward the front and rear walls 24 at the lower portion of the central portion 41 a of the link member 41, and a fixed locking that protrudes toward the link member 41 on the front and rear walls 24. Locked to the portion 24a. The spring 42 urges the link member 42 so that the lid 3 is closed.

  Among the components constituting the storage box, the spring 42 and the spring 33e are made of metal, but the others are made of resin.

Next, the operation of the storage box of this embodiment will be described. As shown in FIGS. 4 and 6, when the lid 3 is in the closed state, the distal end shaft holes 41 g and 41 h of the link member 41 are detachably fitted to the lid side rotation center portions 35 a and 35 b of the lid 3. The link member 41 is at a position that is symmetric with respect to the straight line in the vertical direction with the main body side rotation center portion 25 as the center. The positions of the left and right lid side rotation center portions 35a and 35b at this time are the reference positions P _L 0 and P _R 0. The tip shaft holes 41g and 41h of the link member 41 are located at the same position as this reference position. The movable locking portion 41j of the link member 41 is positioned at the center in the left-right direction together with the fixed locking portion 24a of the box body 2, and is clamped from both the left and right sides by the end portions 42b and 42c of the spring 42.

  A case where the right side of the lid 3 is opened will be described. As shown in FIG. 5, when the right operation portion 33a of the lid 3 is pushed inward, the right transmission member 34a engaged with the link hole 33c on the front side of the operation portion 33a moves to the rear side and is transmitted. The lid-side rotation center portion 35a provided at the tip of the member 34a is retracted into the hole 31g and is detached from the tip shaft hole 41g of the link member 41. The transmission member 34b engaged with the link hole 33d on the rear side of the operation portion 33a moves forward, and the link side rotation center provided at the rear end is located on the rear side of the box body 2. The member 41 is detached from the tip shaft hole 41g. On the other hand, since the left operation portion 33 b is not operated, the left transmission member 34 b does not move, and the left and front lid-side rotation center portions 35 b are connected to the link member 41.

  Then, as shown in FIG. 8, when the right side of the lid 3 is lifted upward while pushing the right operation portion 33a, the lid 3 rotates about the left lid side rotation center portion 35b. When the right side of the lid 3 is rotated to the maximum angle, the lower surface 31e of the base portion 31 of the lid 3 rises in a substantially vertical direction, the left side surface 31d of the lid 3 wraps around the lower portion of the lid 3, and It abuts on the upper left surface of the side peripheral edge 22.

  Here, as shown in FIG. 6, the distance L1 between the lid side rotation center portion 35 b of the lid 3 and the left side surface 31 d of the lid 3 is the lower surface of the lid side rotation center portion 35 b and the base portion 31 of the lid 3. It is larger than the distance L2 with 31e. For this reason, when the lid 3 is rotated from the closed state to the open state on the right side, the left side surface 31d of the lid 3 abuts on the left upper surface of the box body 2, and the left lid side rotation center portion 35b rises. . The lid 3 is connected to the link member 41 at the lid-side rotation center portion 35b. When the left lid-side rotation center portion 35b rises, the link member 41 rotates in the clockwise direction in FIG. 8 around the body-side rotation center portion 25, and the lid-side rotation center portion 35b moves to the side surface of the box body 2. It moves to the direction which leaves | separates, ie, the center part of the left-right direction of the box main body 2. Therefore, in the lid open state, the thick lid 3 is pulled in to the center side in the left-right direction, and does not jump out of the box body 3 to the outside.

  The left end shaft hole 41 h of the link member 41 is urged downward by the urging force of the spring 42. For this reason, the left end shaft hole 41h presses the left side surface 31d of the lid 3 against the upper surface of the box body 3 via the lid side rotation center portion 35b. Therefore, the lid 3 can maintain the open state stably.

Further, the position of the left lid side rotation center portion 35b at this time is P _L +1 above the reference position P _L 0, and the left end shaft hole 41h of the link member 41 is at this position. And the link member 41 rotates clockwise in FIG. 8 by the raise of the lid side rotation center part 35b on the left side. The left arm 41a of the link member 41 is raised and the right arm 41b is lowered. When the link member 41 is rotated to the maximum angle by the rotation of the lid 3, the right end 41d of the link member 41 closes the right hole 23b of the box body 2, and the back surface 41i of the tip 41d is the hole 23b. It constitutes the same surface as the periphery. The position of the right end shaft hole 41g at this time is a position P _L -1 below the reference position P _L 0.

Next, in order to open the left side of the lid 3, as shown in FIG. Then, as shown in FIG. 9, the left lid-side rotation center portion 35 b is detached from the distal end shaft hole 41 h of the link member 41 through the left transmission member 34 b. In this state, when the left side of the lid 3 is lifted, the lid 3 rotates around the lid side rotation center portion 35 a on the right side of the lid 3. When the lid 3 rotates to the maximum angle, the right side surface 31 d of the lid 3 turns around the lower portion of the lid 3 and comes into contact with the upper right side of the side peripheral edge 22 on the upper surface of the box body 3. Right lid side rotation center portion 35a is located at a higher position _P R +1 than the reference position _{P R} 0. On the other hand, the tip shaft hole 41h on the left side of the link member 41 descends to a position P _L −1 lower than the reference position P _L 0. The left tip 41d closes the left hole 23b, and the back surface 41i of the tip 41d is flush with the periphery of the hole 23b.

  In the first embodiment, the distance L1 between the lid side rotation center portions 35a and 35b of the lid 3 and the left and right side surfaces 31d of the lid 3 is the distance between the lid side rotation center portions 35a and 35b and the base portion 31. It is larger than the distance L2 with the lower surface 31e. For this reason, the left and right side surfaces 31d of the lid 3 are in contact with the side peripheral edge portion 22 of the upper surface of the box body 2 regardless of whether the left side or the right side of the lid 3 is opened from the closed state. The other of the left and right lid-side rotation center portions 35a and 35b is raised, and the lid 3 is pulled to the center side in the left-right direction. Therefore, the lid 3 in the open state does not jump out greatly from the side surface of the box body 2.

  Further, the lid side rotation center portions 35 a and 35 b are provided at positions close to the lower surface 31 e of the lid 3. Therefore, it is not necessary to form a recess for providing the lid side rotation center portions 35a and 35b in the cushion portion 32 of the lid 3. Therefore, the thickness of the entire area of the cushion portion 32 can be made uniform.

  Moreover, the storage box of this embodiment is a storage box provided in the center console of the vehicle. As described above, the lid-side rotation center portions 35a and 35b are provided at positions close to the lower surface 31e of the lid 3, so that the cushion member 32 for the armrest of the occupant disposed on the upper portion of the lid 3 is substantially planar. It can be formed with a uniform thickness. For this reason, the occupant can comfortably place the elbow on the cushion member 32.

  In addition, a slide portion 31 a that is long in the front-rear direction is provided on the base portion 31 of the lid 3. Since the lid-side rotation center portions 35a and 35b are provided at positions close to the lower surface of the lid 3, the lid-side rotation center portions 35a and 35b are not an obstacle to the space for providing the slide portion 31a.

  When one of the left side and the right side of the lid 3 is in the open state, the other lid side rotation center portion 35a, 35b of the left side and the right side rises. Therefore, it is not necessary to secure a gap for the rotation of the lid 3 when the lid 3 is in the closed state. Further, as shown by a two-dot chain line in FIG. 1, even when the side surface 31d of the lid 3 is not parallel to the axial direction of the lid-side rotation center portions 35a and 35b, when the lid is open, the side surface 31d of the lid 3 Since the bulging portion 31 h that bulges outward is in contact with the side peripheral edge portion 22 on the upper surface of the box body 3 and rises while rotating, there is no possibility that the bulging portion 31 h interferes with the upper surface of the box body 3. Therefore, it is not necessary to increase the gap for rotating the lid. Moreover, the freedom degree of the design of the lid 3 is high.

  Further, when one of the left side and the right side of the lid 3 is in an open state, the distal end portion 41d of the link member 41 in the vicinity of the other left and right lid side rotation center portions 35a, 35b is located between the box body 2 and It's just a glimpse. Since the vicinity of the main body side rotation center portion 25 in the link member 41 is disposed inside the box main body 2, the outer appearance is not seen even when the lid 3 is opened. Therefore, it looks good.

  Moreover, since the lid 3 and the box main body 2 are connected by the link member 41 which is one part, the number of parts is small.

  The link member 41 is supported by the main body side rotation center portion 25 at a position lower than the lid side rotation center portions 35a and 35b on both the left and right sides. For this reason, a portion of the left and right sides of the link member 41 that opens the lid 3 is lowered. Therefore, the link member 41 does not protrude from the opening periphery of the box body 2 on the open side of the lid 3. Therefore, the access when the stored item is taken in and out of the opening 21 of the box body 2 is not hindered by the link member 41. Further, the link member 41 cannot be seen from the opening peripheral edge of the box body 2 on the side where the lid 3 is opened, and the appearance is good.

  The pair of front and rear link members 41 are opened and closed on both the left and right sides. Therefore, an increase in the number of parts can be suppressed, and the double-opening type storage box can be configured simply.

  When one of the left side and the right side of the lid 3 is opened, one of the left and right hole portions 23b formed in the box body 2 is closed on the same plane as the peripheral edge of the hole portion by one of the left and right rear surfaces 41i of the link member 41. Can be removed. Therefore, the appearance of the periphery of the opening 21 of the box body 2 is good. Further, there is no possibility that foreign matter will fall into the inside of the box body 2 from the hole 23b.

  The spring 42 is disposed in the main body side rotation center portion 25 that is separated from the lid side rotation center portions 35a and 35b. For this reason, compared with the case where the spring 42 is provided in lid side rotation center part 35a, 35b, the rotational moment required in order to regulate rotation of the lid 3 becomes small. Therefore, the urging force of the urging means necessary to maintain the lid in the closed state may be small.

  When the lid 3 is opened, the side surface 31 d of the base portion 31 of the lid 3 goes around the lower portion of the lid 3 and comes into contact with the side peripheral edge portion 22 on the upper surface of the box body 2. At this time, the side surface 31d of the base portion 31 may be rubbed with the side peripheral edge portion 22 of the upper surface of the box body 2 and the contact portion may be damaged. Therefore, for example, as shown in FIG. 1, a roller 29 is provided on the side peripheral edge 22 on the upper surface of the box body 2. The roller 29 is preferably embedded in the side peripheral edge portion 22 and a part of the peripheral surface thereof is exposed on the upper surface of the side peripheral edge portion 22 so that the side surface 31 d of the base portion 31 contacts the peripheral surface of the roller 29.

(Second Embodiment)
As shown in FIG. 10, the second embodiment is a single-open storage box that can be opened and closed only on the right side of the lid 3. Is different.

  The single-open storage box 10 includes a box body 2 provided with a storage space 20 having an opening 21 above, a lid 3 that covers the opening 21 so that the opening 21 can be opened and closed from the right side, and front and rear peripheral edges of the opening 21. 23 and a link member 41 provided on the left side.

  As shown in FIG. 11, unlike the first embodiment, the link member 41 is provided with an arm portion 41b, a bent portion 41c, and a tip portion 41d only in the left direction from the central portion 47, and on the right side. The arm part, the bent part, and the tip part are not provided. The central shaft hole 41e formed in the central portion 47 of the link member 41 is inserted through the main body side rotation center portion 25 protruding from the fixed wall 23a provided on the front side and the rear side of the opening 21 of the box main body 2. The box body 2 is rotatably supported. A distal end shaft hole 41 h formed in the left end portion 41 d of the link member 41 is inserted into the lid side rotation center portion 35 b provided in the base member 31 of the lid 3 and is supported rotatably with respect to the lid 3. Has been. In the present embodiment, unlike the first embodiment, the lid-side rotation center portion 35b always maintains the state of being inserted into the distal end shaft hole 41h.

  In the present embodiment, the operation unit and the transmission member are not used. Others are the same as in the first embodiment.

  In the present embodiment, when the right side of the lid 3 is lifted upward, the right side of the lid 3 is opened around the lid side rotation center portion 35b on the left side of the lid 3. When the right side of the lid 3 is rotated to the maximum angle, the lower surface 31e of the base portion 31 of the lid 3 rises in a substantially vertical direction, the left side surface 31d of the lid 3 wraps around the lower portion of the lid 3, and It abuts on the upper left surface of the side peripheral edge 22.

  Here, also in the present embodiment, as in the first embodiment, the distance between the lid side rotation center portion 35b of the base portion 31 of the lid 3 and the left side surface 31d of the lid 3 is the lid side rotation center. It is larger than the distance between the portion 35 b and the lower surface 31 e of the base portion 31. For this reason, when the lid 3 is rotated from the closed state to the open state, the left side surface 31d of the lid 3 comes into contact with the left upper surface of the box body 2, and the left lid-side rotation center portion 35b rises. The link member 41 moves the lid-side rotation center part 35b in a direction away from the side surface of the box body 2. Therefore, in the lid open state, the thick lid 3 is pulled in to the center side in the left-right direction, and does not jump out of the box body 3 to the outside.

  When one of the left side and the right side of the lid 3 is in the open state, the other lid side rotation center portion 35a, 35b of the left side and the right side rises. Therefore, it is not necessary to secure a gap for the rotation of the lid 3 when the lid 3 is in the closed state. Further, as shown by a two-dot chain line in FIG. 1, even when the side surface 31d of the lid 3 is not parallel to the axial direction of the lid-side rotation center portions 35a and 35b, when the lid is open, the side surface 31d of the lid 3 Since the bulging portion 31 h that bulges outward is in contact with the side peripheral edge portion 22 on the upper surface of the box body 3 and rises while rotating, there is no possibility that the bulging portion 31 h interferes with the upper surface of the box body 3. Therefore, it is not necessary to increase the gap for rotating the lid. Moreover, the freedom degree of the design of the lid 3 is high.

  Also in the second embodiment, it is preferable to provide the rollers 29 on both the front and rear sides of the side peripheral edge portion 22 as in the first embodiment.

The upper end 45b of the arm 45 connected to the lid 3 gradually tilts to the left (clockwise) while moving upward. As a result, the engagement between the rack gear 45a of the arm 45 and the pinion gear 44a of the rotary shaft 44 causes the arm 45 to move downward with respect to the rotary shaft 44, while the meshing portion of the rack gear 45a and the pinion gear 44a Displaced to the right relative to the upper end 45b, the lower end 45c of the arm 45 rotates clockwise in FIGS. 16 and 17 with respect to the upper end 45b.

  Along with this, the rotation base 43 pivotally supporting the rotation shaft 44 also rotates in the rotation direction of the arm 45. By the meshing of the pedestal side gear 43e and the link side gear 41k, the rotating pedestal 43 rotates the link member 41 counterclockwise on the opposite side to the rotating direction of the rotating pedestal 43. That is, the link member 41 rotates in a direction opposite to the rotation direction of the arm 45. The lid 3 is supported by a four-bar link structure including the lid 3, the arm 45, the link member 41, and the rotary base 43. Therefore, as the lid 3 is opened and closed, the side surface 31d on the right side of the lid 3 and the upper surface of the box body 2 do not need to be in contact with each other during opening and closing, and the friction between them can be alleviated.

  Further, the left side surface 31 d of the lid 3 turns around to the lower part without coming into contact with the upper surface of the box body 2 due to the rise of the left side of the link member 41 by the four-bar linkage mechanism. The link member 41 rotates around the main body side rotation center portion 25 and moves the left lid side rotation center portion 35 b toward the central portion in the left-right direction of the box main body 2. Therefore, in the lid open state, the thick lid 3 is drawn to the center side in the left-right direction, so that it does not jump out from the box body 2 to the outside. As the left arm 41a of the link member 41 rises, the right arm 41b descends and retreats to the right hole 23b of the box body 2.

  When the lid 3 is closed from the open state, the arm 45 gradually moves closer to parallel to the vertical direction while moving downward. Eventually, the arm 45, the rotation shaft 44, the rotation base 43, and the link member 41 return to the initial positions.

  Next, when the left side of the lid 3 is opened, the left side of the lid 3 is lifted while pushing the operation part on the left side of the lid 3 inward. As a result, as in the first embodiment, the left lid-side rotation center portion 35b is detached from the tip shaft hole 41h of the link member 41, and the lid 3 is centered on the right lid-side rotation center portion 35a. Rotate. The arm 45, the rotating shaft 44, the rotating pedestal 43, and the link member 41 rotate in a direction opposite to the left and right directions when the right side is opened.

  That is, the upper end portion 45b of the arm 45 is gradually inclined rightward while moving upward. The meshing portion of the rack gear 45a of the arm 45 and the pinion gear 44a of the rotating shaft 44 is displaced to the left with respect to the upper end portion 45b of the arm 45, and rotates counterclockwise in FIGS. The rotating shaft 44 and the rotating pedestal 43 also rotate in the same direction as the arm 45. The link member 41 rotates to the side opposite to the rotation base 43. That is, the link member 41 rotates in a direction opposite to the rotation direction of the arm 45 to raise the lid-side rotation center portion 35a that supports the right end portion 41d of the link member 41, and the left end portion. 41a is lowered. As the link member 41 is raised on the right side, the right side surface 31 d of the lid 3 smoothly turns to the lower part without coming into contact with the upper surface of the box body 2.

  In the present embodiment, the lid 3 is supported by a four-bar link structure including the lid 3, the arm 45, the link member 41, and the rotary base 43. Therefore, as the lid 3 is opened and closed, the side surface 31d of the lid 3 and the opening periphery of the box body 2 do not contact each other during the opening and closing. Therefore, the lid 3 can be opened and closed more smoothly.

  The rotation base 43 is disposed at the center in the left-right direction of the box body 2, and the upper end 45 b in the longitudinal direction of the arm 45 is rotatably connected to the center in the left-right direction of the lid 3. For this reason, the lid 3, the arm 45, the link member 41, and the rotating pedestal 43 can form a four-bar linkage mechanism when the lid 3 opens and closes to the left and right. Therefore, the lid 3 can be smoothly opened and closed on both the left and right sides.

  Similarly to the first embodiment, one of the left and right lid-side rotation center portions 35a and 35b is raised by the one of the left and right rises of the link member 41, and the left and right sides of the lid 3 are raised. 31d turns around to the lower part without contacting the upper surface of the box body 2. The link member 41 rotates around the main body side rotation center portion 25 and moves one of the left and right lid side rotation center portions 35a and 35b toward the central portion of the box main body 2 in the left-right direction. Therefore, in the lid open state, the thick lid 3 is drawn to the center side in the left-right direction, so that it does not protrude greatly from the box body 3 to the outside.

  In the third embodiment, the arm 45, the rotation shaft 44, and the rotation base 43 are provided on both the front side and the rear side of the box body 2, but may be provided only on the front side or only on the rear side. When provided on the front side, even if a load is applied to the lid 3 during operation of the operation parts 33a and 33b, the arm 45 and the rotating pedestal 43 are arranged on the front side and the rear side closer to the operation parts 33a and 33b. As a result, the moment applied to the arm 45 and the rotating base 43 can be reduced. Moreover, the twist of the lid 3 can also be suppressed. On the other hand, when it is provided only on the rear side, there is no arm 45 on the front side, and access to the opening 21 can be facilitated.

  In the third embodiment, the arm 45, the rotation shaft 44, and the rotation base 43 are provided in the double-opening storage box 10, but these may be provided in a single-opening storage box as in the second embodiment.

  In the third embodiment, the spring 42 is disposed on the main body side rotation center 25, but may be disposed on the rotation shaft 44. That is, the spring 42 is wound around the peripheral surface of the rotating shaft 44, one end 42 b of the spring 42 is locked to the rotating shaft 44, and the other end 42 c is locked to the rotating base 43. The spring 42 is biased in a direction that restricts the rotation of the rotation shaft 44. Also in this case, the rotation shaft 44 on which the spring 42 is disposed is disposed on the main body side rotation center portion 25 away from the lid side rotation center portions 35a and 35b. Compared with the case where the springs 42 are provided on 35a and 35b, the rotational moment required to restrict the rotation of the lid is reduced. Therefore, the urging force of the urging means necessary for maintaining the lid in the closed state may be small.

  The right end shaft hole 41 h of the link member 41 is urged downward by the urging force of the spring 42. For this reason, the right end shaft hole 41h presses the right side surface of the lid 3 against the upper surface of the box body 3 via the lid side rotation center portion 35b. Therefore, the lid 3 can maintain the open state stably.
