In the case of this embodiment, one corner of the quadrilateral has a circular arc shape.

  In addition, a pair of guide portions 26, 26 project from both sides of the lid 20 in the width direction at a height substantially the same as that of the recess 24. The guide portion 26 is formed with an insertion hole 27 through which a latch 62 of links 60a and 60b, which will be described later, is inserted, and the latch 62 is slidably supported.

  A lock device that can be opened and closed with respect to the opening 12 is provided on the back surface of the lid 20. The locking device mainly includes an operating element 30 mounted on the front side of the lid 20, a crank 50 attached to the back side of the lid 20, a pair of links 60 a and 60 b connected to the crank 50, and the crank 50. It is comprised from a pair of connected reaction force provision board 70a, 70b.

  Further, the operation element 30 is disposed in the recess 24 of the lid 20 (see FIGS. 5 and 6). The operation element 30 has a disk-shaped base 31 that abuts against the bottom wall of the recess 24, and a knob 32 protruding at a constant width is formed on the front side of the base 31. The knob 32 is gripped with fingers or the like and rotates the operation element 30. A rotating shaft 33 extends perpendicularly from the center of the back side of the base portion 31. A pair of groove portions 34 are opposed to the axial center of the rotating shaft 33 and are formed along the axial direction. A protrusion 53 of a crank 50 (to be described later) is fitted into the groove 34, and the operation element 30 and the crank 50 are fixed by an adhesive or the like.

  A pedestal 40 is attached to the recess 24 of the lid 20 from the back side of the lid 20. The pedestal 40 has a circular base plate 41 in which an insertion hole 42 into which the rotation shaft 33 is inserted is formed. A protrusion (not shown) protrudes from one end in the axial direction of the base plate 41 in a shape that fits the inner periphery of the through hole 25 of the lid 20, and the outer periphery of the protrusion is locked to the inner periphery of the through hole 25. It becomes a detent. In addition, a pair of arc-shaped ribs 43 and 43 are formed on the back side of the base plate 41 so as to face each other with the insertion hole 42 as a center.

  Further, the crank 50 is inserted into the internal space of the pair of arc-shaped ribs 43, 43. The crank 50 has a cylindrical base 51 in which an insertion hole 52 into which the rotary shaft 33 is inserted is formed. The cylindrical base 51 is inserted into the inner space of the arc-shaped ribs 43, 43, and the swinging operation of the crank 50 is guided by the inner periphery of the arc-shaped rib 43 to realize a stable operation.

  In addition, a pair of protrusions 53, 53 project oppositely on the inner periphery of the insertion hole 52, and the protrusions 53, 53 are fitted into the grooves 34, 34 of the rotary shaft 33, and are operated by means such as an adhesive. 30 and the crank 50 are fixed. Instead of the adhesive or the like, the rotary shaft 33 and the crank 50 may be fixed by press-fitting the rotary shaft 33 into the insertion hole 52 or screwing with a screw or the like.

  Further, a pair of connecting portions 54, 54 are provided so as to protrude outward in the circumferential direction of the cylindrical base portion 51, and the connecting portions 54, 54 are formed at the end of the arc-shaped rib 43 of the base 40. It abuts and regulates the rotation angle of the crank 50 to form a stopper in the protruding direction and the retracting direction of the links 60a and 60b.

  Referring also to FIG. 2, the links 60a and 60b and the reaction force applying plates 70a and 70b are connected to the pair of connecting portions 54 and 54 of the crank 50, respectively.

  Each of the pair of links 60a and 60b has one end connected to the opposing connecting portion 54 of the crank 50 via a connecting piece 61, extends in the opposite direction, and a latch 62 is formed at the other end. The latch 62 is inserted into an insertion hole 27 provided in the guide portion 26 and is slidably supported. The connecting piece 61 is thinner than the link 60 and has flexibility when compared with the thickness of the link 60 when viewed from the direction perpendicular to the back surface of the lid 20. Sometimes it is easy to bend.

  By supporting the links 60a and 60b with the guide portion 26, the links 60a and 60b can be supported with a certain distance from the back surface of the lid 20, so that the wall portion 11 in the vehicle interior has a complicated curved shape. Even when the lid 20 is curved in accordance with this, the links 60a and 60b can be slidably held.

  Further, the latch 62 is formed with a tapered surface 62 a that gradually decreases from the middle toward the tip on the opposite side of the engagement surface with the opening 12 of the lid 20. According to this, when the lid 20 is fitted into the opening 12, the tapered surface 62 a comes into contact with the peripheral edge of the opening 12 and is pressed as it is, and the latch 62 is pulled inside the lid 12 and passes through the peripheral edge of the opening 12. Is elastically biased and returns to its original position. Therefore, it is not necessary to rotate the operating element 30 and pull the latch 62 into the lid 20, and it is possible to simply lock the opening 12 in the closed state simply by fitting it into the inner periphery of the opening 12.

  Further, the intermediate portions 63 of the links 60a and 60b are provided with projections 64 on at least one side surface, in this embodiment both side surfaces. In the case of this embodiment, the intermediate portion 63 is formed at three positions with a predetermined interval.

  One end of the reaction force applying plates 70a and 70b is connected to the opposing connecting portion 54 of the crank 50 via a thin hinge 71, and in the opposite direction to the links 60b and 60a connected to the same connecting portion 54. It is growing.

  Further, as shown in FIGS. 1 and 4, an engaging portion 72 is formed at the other end of the reaction force applying plates 70 a and 70 b so as to be bifurcated and project in the axial direction. By engaging the protrusions 64 of the intermediate portion 63 of the links 60a and 60b, the reaction force applying plates 70a and 70b are connected to the intermediate portions of the links 60a and 60b in a curved state.

  One reaction force application plate 70a is connected to one link 60a and urges the link 60a in the direction of pushing outward, and the other reaction force application plate 70b is connected to the other link 60b. The link 60b is urged in the direction of pushing outward.

  That is, since the link 60a and the reaction force applying plate 70a and the link 60b and the reaction force applying plate 70b that are paired with each other are connected to the opposing connecting portion 54 of the crank 50, as shown in FIG. Can be elastically biased in the direction of pushing the link 60 outward by effectively bending the reaction force applying plates 70a and 70b.

  Further, the reaction force applying plates 70a and 70b are connected to the connecting portion 54 via the thin hinge portion 71. Therefore, the reaction force applying plates 70a and 70b are easily bent at the hinge portion 71, as shown in FIG. The plates 70a and 70b can be greatly bent easily.

  Further, the reaction force application plates 70 a and 70 b have a rectangular cross section, and the one end of the crank 50 and the intermediate portion of the link 60 so that the wide side is positioned perpendicular to the back surface of the lid 20. 63 (see FIG. 1). For this reason, it becomes easy to bend in the direction perpendicular | vertical with respect to the wide surface of the reaction force provision board 70, and durability can be improved also with respect to repeated bending.

  Further, as shown in FIG. 4, both sides of the intermediate portion 63 of the links 60 a and 60 b are sandwiched between the engaging portions 72 of the reaction force applying plates 70 a and 70 b, and the engaging portions 72 engage with the protrusions 64, Since the force application plate 70 and the link 60 are connected, the reaction force application plates 70a and 70b are bent and the reaction force application plates 70a and 70b as the link 60 swings as shown in FIG. Even if the direction of the end portion of the link is changed, the engaging portion 72 slides on the side surface of the link 60, so that the elastic restoring force can be effectively applied in the direction in which the links 60a and 60b are pushed out. The torque for turning the operating element 30 does not increase and it is difficult to turn.

  Further, the reaction force applying plates 70a and 70b and the links 60a and 60b can be easily connected with one touch only by engaging the bifurcated engaging portion 72 with the protrusion 64. For example, the engaging portion 72 has a shape as shown in FIG. That is, a pair of elastic pieces 72a and 72a which are bifurcated and protrude in the axial direction are provided from the other ends of the reaction force applying plates 70a and 70b, and are opposed to each other from the inner ends of the elastic pieces 72a and 72a. A pair of claw portions 72b and 72b are formed. Further, the claw portion 72b is formed with a tapered surface 72c so as to be easily inserted into the link 60. According to this, after inserting the engaging portion 72 into the intermediate portion 63 of the links 60a and 60b, the claw portion 72b engages with the links 60a and 60b, so that the reaction force applying plates 70a and 70b come off from the link 60. Can be prevented.

  As described above, since the protrusions 64 are formed at three positions at a predetermined interval in the intermediate portion 63 of the links 60a and 60b, for example, when engaged with the protrusions 64 on the crank 50 side, When the elastic restoring force of the force applying plates 70a and 70b is increased and engaged with the protrusions 64 on the latch 62 side, the elastic restoring force of the reaction force applying plates 70a and 70b can be weakened, and the elastic restoring force can be adjusted appropriately. It becomes.

  In the case of this embodiment, one end of the links 60a and 60b is connected to one end of the crank 50, and one end of the reaction force applying plates 70a and 70b is connected to the other end of the crank 50, and the reaction force applying plate 70a, The other end of 70b is injection-molded in a state where it is not connected to the intermediate portion 63 of the links 60a and 60b, and the other end of the reaction force applying plates 70a and 70b is bent to the intermediate portion 63 of the links 60a and 60b. By connecting in a state, the latches 62 of the links 60a and 60b are elastically biased in the direction of pushing the lid 20 outward. This is because when the reaction force applying plates 70a and 70b and the intermediate portion 63 of the links 60a and 60b are connected in advance and the reaction force applying plates 70a and 70b are formed in a curved state, no elastic restoring force is generated. It is.

  In this embodiment, the crank 50, the links 60a and 60b, and the reaction force applying plates 70a and 70b are integrally formed. According to this, since the crank 50, the links 60a and 60b, and the reaction force applying plates 70a and 70b can be integrally formed, the manufacturing cost can be reduced and the assembling work can be facilitated.

  In addition, the member demonstrated above is shape | molded, for example with synthetic resins, such as polyoxymethylene (POM) and polyamide (PA).

  Next, the assembly procedure and operation of the lid opening / closing device having the above configuration will be described.

  First, the operation element 30 is inserted into the recess 24 from the front side of the lid 20, and the rotary shaft 33 is projected to the back side of the lid 20, and a projection (not shown) of the base 40 is inserted into the through hole 25 from the back side of the lid 20. The base 40 is attached to the back side of the lid 20 while being prevented from rotating.

  Next, after aligning the projection 53 and the groove portion 34 of the rotary shaft 33 with the crank 50 coated with adhesive on the inner periphery of the insertion hole 52, the cylindrical base portion 51 is inserted into the arc-shaped rib 43, and the operator 30 and the crank 50 are fixed.

  Then, the latches 62 at the ends of the links 60a and 60b are inserted into the insertion holes 27 of the guide part 26, and the latches 62 are slidably supported, and the engaging parts 72 of the reaction force applying plates 70a and 70b are connected to the link 60a. , 60b, the reaction force applying plates 70a, 70b are connected in a bent state to the intermediate portions of the links 60a, 60b, and end portions of the links 60a, 60b by the elastic restoring force. The latch 62 is elastically biased in the direction of pushing the latch 20 outward.

  And it will be applied to the opening part 12 formed in the wall part 11 in the compartment 10 shown in FIG. That is, after the claw 23 is locked to the lower peripheral edge of the opening 12, the latch 62 is pressed to the peripheral edges of the opening 12 via the tapered surface 62 a simply by pushing the lid 20 into the opening 12. Since it is drawn inward and passes through the opening 12 and is pushed out again and engages with the periphery of the opening 12, the opening 12 can be easily locked in a closed state (see FIG. 5). Further, since the latches 62 are engaged with the peripheral edges on both sides of the opening 12, there is little backlash and the installation is improved.

  When the operator 30 is rotated while holding the knob 32, the latches 62 of the links 60a and 60b are both pulled into the lid 20, and the engagement between the latch 62 and the peripheral edges on both sides of the opening 12 is released. The lid 20 can be opened (see FIG. 6). At this time, the reaction force imparting plates 70a and 70b are made of a relatively long curved plate material, and even if the lid 20 is repeatedly bent as the lid 20 is opened and closed, deterioration due to stress concentration does not easily occur, and the latch 62 is placed outside the lid 20. Prevents the elastic biasing force to be lowered.

  The opening 12 is an opening of an accommodation space formed between the vehicle body panel and the wall portion 11, and a tool such as a jack is accommodated in the accommodation space. In the case of this embodiment, although applied to the lid which opens and closes the side wall of the compartment 10, you may apply to the lid which opens and closes the bottom wall of the compartment 10, and the lid which opens and closes a glove box.

  In this embodiment, the latch 62 is engaged with the peripheral edge of the opening 12. For example, when a wall projecting on the peripheral edge of the opening is formed, the latch 62 is connected to the wall. An engagement hole to be engaged may be provided to lock the opening 12 in a closed state.

  7 and 8 show another embodiment of the lid opening / closing device of the present invention. Note that substantially the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In the case of this embodiment, a C-shaped fitting recess 54 a that opens in a direction perpendicular to the longitudinal direction of the crank 50 is formed at the end of one connecting portion 54 of the crank 50. Further, as shown in FIG. 7B, the intermediate portion in the height direction of the connecting portion 54 in which the fitting recess 54a is formed has a sliding groove 54b that is notched with a predetermined width and communicates with the fitting recess 54a. Is formed. Further, the connecting piece 61 as in the above-described embodiment is not formed at the end of the link 60 opposite to the latch 62, and the link 60a and 60b are sized to fit into the fitting recess 54a. A cylindrical fitting convex portion 61a that protrudes into the center is formed (see FIG. 7C). The links 60 a and 60 b are formed with pin-shaped protrusions 73 on the side surfaces near the latch 62, and are connected to one ends of the reaction force applying plates 70 a and 70 b via the protrusions 73. The other ends of the reaction force applying plates 70 a and 70 b are connected to the connecting portion 54 of the crank 50 via the hinge portion 71.

  When the fitting convex portion 61a is pushed into the fitting concave portion 54a, the opening peripheral edge of the fitting concave portion 54a is deformed and inserted into the fitting concave portion 54a, and then elastically returns to the fitting concave portion 54a. The portion 61a is prevented from coming off and fitted, and the latch 62 of the links 60a and 60b is elastically biased in the direction of pushing the lid 20 outward. Thus, in this embodiment, one end of the reaction force applying plates 70a and 70b is connected to one end of the crank 50, the other end of the reaction force applying plate 70 is connected to the intermediate portion 63 of the link 60, and the link Since one end of 60 is injection-molded without being connected to one end of the crank 50, the crank 50, the links 60a and 60b, and the reaction force applying plates 70a and 70b can be integrally formed, reducing the manufacturing cost and assembling work. Improves performance.
