Each rod 4 is provided on the corresponding side surface 11, 21 of the case main body 1 and the lid 2, and a portion slightly below the middle is screwed to a mounting portion provided at a substantially intermediate portion in the upper front-rear direction of the case main body 1. The other end side is rotatably connected to a mounting portion provided at the front end portion of the lid 2 by a shaft member 18b such as a screw.

  Here, the second rod 4 has a shaft member 18a that pivots at a position slightly below the middle, as estimated from the locus b of the shaft member 18b on the other end side shown in FIG. As described above, the arrangement and length of the lid 2 are devised so that the front end side of the lid 2 moves from the case main body 1 upward in a circular arc shape through the shaft member 18b on the other end side of the rod 4 from the closed state. . In other words, the length of the rod 4 is r2 when the length connecting the shaft member 18a pivoting at a position slightly below the middle in FIG. 7 and the shaft member 18b on the other end side is r2. Is set to a length of ½ or more of the opening width (opening width on the main storage portion side) w of the case body 1. As described above, this is the locus b where the second rod 4 has the lower shaft member 18a as a fulcrum, and the front end of the lid 2 is located above the case body 1 via the shaft member 18b on the other end of the rod. By making it moveable in a circular arc shape, it is difficult to interfere with the vicinity of the opening of the case main body 1 and the lid 2 can be stably supported together with the first rod 3.

   The urging means 5A, 5B may be of a spring configuration that urges the lid 2 in the opening direction via the first rod 3 or the second rod 4. In this embodiment, as is inferred from FIGS. 1 and 4, the biasing means 5 </ b> A uses a generally V-shaped torsion spring, is located on the corresponding side surface 11 of the case main body 1, and has a substantially intermediate winding portion 5 c. Is attached to the outer periphery of the cylindrical mounting portion that stops the shaft member 17a, the one end 5a side is locked to the corresponding portion of the first rod 3, and the other end 5b side is provided on the side surface 11 while exerting a biasing force. It is arranged in a state of being locked to the front upper projection 19a. As shown in FIG. 5, the urging means 5 </ b> B uses a coil spring and is on the corresponding side surface 11 of the case body 1, and the one end 5 d side is engaged with a locking portion 41 provided on one end side of the rod 4. The other end 5e side is arranged in a state of being locked to the lower middle projection 19b provided on the side surface 11 while expressing the urging force.

  The locking means 6 is provided corresponding to the engaging portion 40 provided on one end side of the second rod 4 arranged on the side of FIG. 4, and the lid 2 is attached by locking the engaging portion 40. Any configuration that can be held in the closed state against the biasing force of the biasing means 5A, 5B may be used. In this embodiment, the lock means 6 is a unit product composed of a push-push locking mechanism as shown in FIG. 6, and is attached to a substantially frame-shaped holding body 19c attached to the rear upper side of the side surface 11 with a screw or the like. It is installed. The structure includes a housing 23 that is open on the front side, a sliding body 25 that is housed on the rear side of the housing 23 and has a pair of clamping pieces 24 that engage and disengage the engaging portion 40, and a non-energizing force for the sliding body 25 in one direction. The illustrated heart, a heart cam groove 26 provided in the sliding body 25, a tracer 27 pivotally supported in the housing 23, and protrudes from the tracer 27 to engage with the heart cam groove 26. It consists of pins 28 and the like that go around. In this locking mechanism, the lid 2 is urged in the opening direction by the urging means 5A and 5B, and the engaging portion 40 of the second rod 4 is locked via the clamping portion 24. Is released by pushing the lid 2 further in the closing direction. 7 and 8, a part of the locking means 6 is omitted or simplified.

  The damper means 7 may be configured to have a rotation gear 43 that is attached to the one side surface 11 of the case body 1 and meshes with the gear portion 30 provided on the first rod 3. In this embodiment, the damper means 7 has a rotating gear 43 assembled to the case 42, and the rotating gear 43 is braked by receiving the resistance of hydraulic oil in the case 42.

(Operation) In the above structure, when the lid 2 is in the closed state, the second rod 4 is disposed at the foremost position as shown in FIG. 1 and FIG. As described above, as shown in FIG. 6 (a), it is sandwiched between the clamping pieces 24 of the locking means 6, and this state is maintained by the engagement between the pin 28 and the heart cam groove 26. When the lid 2 is switched to the open state, the lid 2 in the closed state is pushed in the closing direction to release the pushing force (release the pushed hand). Then, as shown in FIG. 6B, the pin 28 and the heart cam groove 26 are disengaged, and the sliding body 25 is pushed by the urging force of a spring (not shown), so that both sandwiching pieces 24 protrude out of the housing 23. . For this reason, the engaging portion 40 is released from being pinched by the both pinching pieces 24 and unlocked.

  When the engagement portion 40 is unlocked, the lid 2 is automatically switched from the closed state to the open state in FIG. 4 by the urging force of the urging means 5A and 5B. In this case, the lid 2 has a relationship in which the lengths of the rods 3 and 4 and the connecting positions with respect to the case body 1 and the lid 2 are devised as described above, and the rear end side of the lid 2 is the shaft member 17a on the one end side of the rod 3. 4 is moved to the vicinity of the lower part in the auxiliary storage part 16 of the case main body 1 along the locus a in FIG. In addition, the front end side of the lid 2 extends from the shaft member 18a of the rod 4 as a fulcrum to the upper storage portion 16 of the case body 1 through the shaft member 18b on the other end side of the rod 4 along the arc-shaped locus b of FIG. It moves and it will be in the lid open state of FIG. In this turning process, the gear portion 30 is engaged with the rotating gear 43 of the damper means 7, and the opening speed is braked by the engagement. That is, the lid 2 is rotated at a substantially constant speed from the closed state to the open state by the damper means 7.

  Further, the lid 2 is rotated in the closing direction with the rotation of the first rod 3 and the second rod 4 against the urging force of the urging means 5A and 5B from the open state, and the lid 2 Immediately before reaching the final closed state, the engaging portion 40 on one end side of the rod 4 hits the sliding body 25 and slides the sliding body 25 to the back of the housing 23 against the biasing force of a spring (not shown). In conjunction with this, both clamping pieces 24 sandwich the engaging portion 40 while being pulled into the housing 23 as shown in FIG. At the same time, the pinching piece 24 is locked in the retracted position by the engagement between the pin 28 and the heart cam groove 26. For this reason, the lid 2 is held in the closed state via the second rod 4.

  In the lid opening / closing mechanism described above, in the four-joint link structure composed of the first rod 3 and the second rod 4, the tip end side of the lid 2 is the locus b in FIG. It moves in a large convex arc with a small turning radius (this point has a large rotation angle between the closed position and the open position of about 110 to 130 degrees), and the rear end side of the lid 2 is the longer first 4 is moved by a rod 3 in the locus a in FIG. 4, that is, a small circular arc having a large turning radius (this point has a small rotation angle of 45 to 55 degrees between the closed position and the open position). The space for storing the lid (the space behind the main storage portion 15 or the width of the sub storage portion 16 necessary for making the lid 2 substantially upright in the open state) can be greatly reduced.

  In other words, in this lid opening / closing mechanism, when the lid 2 is in the open state, the lid protrusion amount is inserted into the sub storage portion 16 approaching the main storage portion 15 in a substantially upright manner and protrudes onto the case body 1; The width dimension of the secondary storage portion 16 that is a space for storing the lid, and a relief c notch c (see FIG. 8) set between the main storage portion 15 and the secondary storage portion 16 of the case body 1. Both sizes can be reduced. In addition, it is simpler and easier to assemble than Document 1.
