  However, in the technique of Patent Document 1 described above, the lock mechanism 150 mainly includes a pair of rods 160, 170 slidably mounted on the grab door 120, and a link for synchronizing the slides of the pair of rods 160, 170. Material 180. The lock mechanism 150 is a pair of engaged portions formed at the left and right inner walls 112 a of the opening 112 of the instrument panel 110, each of the tips being the engaging portions 162 and 172 of the pair of rods 160 and 170. It is configured to lock by engaging with each concave hole 112b (see FIG. 18). In other words, the lock mechanism 150 is configured to lock by the two hooks of the engaging portions 162 and 172 of the pair of rods 160 and 170 with respect to the pair of concave holes 112b.

  In such a grab door 120, when the operation of closing the opening 112 of the instrument panel 110 is performed, for example, at the right end (see the arrow in FIG. 19), the right side of the grab door 120 is twisted (the right side of the grab door 120 is the left side). (A more advanced inclination state). When the right side is twisted in this way, the engaging portion (tip) 162 of the rod 160 on the side (right side) on which the closing operation has been performed is changed to the rod on the side (left side) on which the closing operation is not performed. In some cases, the engaging portion (tip) 170 of the 170 may be engaged with the concave hole 112b before the engaging portion (172). At this time, a position shift (a difference between the position of the left concave hole 112b and the position of the engaging portion 172 of the left rod 170) may occur on the side (left side) where the closing operation is not performed. Therefore, since the engaging portion 172 of the rod 170 on the side on which the closing operation is not performed (left side) cannot be engaged with the concave hole 112b, the lock mechanism 150 is in a one-sided state (a state where only the right side is engaged). (See FIG. 19). As a result, even if the glove door 120 is locked in the closed state by the lock mechanism 150, the glove door 120 may be opened due to the vibration generated by the running of the automobile. When the operation of closing the opening 112 of the instrument panel 110 is performed, for example, at the left end, when the operation is performed at the above-described right end, the phenomenon is bilaterally symmetric (the lock mechanism 150 is in a single-sided state (a state in which only the left side is in a state of being locked) ) Will occur.

  An object of the present invention is to solve such a problem, and an object of the present invention is to provide a lock mechanism of a lid which can prevent the operation of closing an opening at an end portion of the lid to be prevented from being in a one-sided state. As an issue.

The present invention has been accomplished to achieve the above object, and is configured as follows.
According to the first aspect of the present invention, a lid is assembled so that an opening formed in an interior member of the vehicle can be opened and closed, and a pair of engagement portions formed on the lid are formed on a pair of covers formed at an edge of the opening. The lid lock mechanism locks the lid in a closed state when the lid is engaged with the engagement portion. The pair of engaging portions includes a rod slidably mounted on the lid and a ratchet rotatably mounted on the lid. The ratchet is rotatable so that the engagement with the engaged portion corresponding to the engaging portion follows the engagement with the engaged portion corresponding to the engaging portion of the rod.

  According to the invention of claim 1, for example, as described in the related art, by performing an operation of closing the opening of the instrument panel at the right end of the lid, the engagement portion of the rod is ahead of the engagement portion of the ratchet. Even if it is engaged with the engaged portion, unlike the related art, the displacement occurring on the side (left side) where the closing operation is not performed can be absorbed by the rotation of the ratchet. Therefore, the engagement portion of the ratchet is engaged following the engagement of the engagement portion of the rod. As a result, the lock mechanism does not enter a one-sided state.

  According to a second aspect of the present invention, there is provided the lid locking mechanism according to the first aspect, wherein the ratchet releases the engagement with the engaged portion corresponding to the engagement portion. The reverse rotation is possible so as to follow the release of the engagement with the engaged portion corresponding to the joining portion.

  According to the invention of claim 2, the structure of the lock mechanism can be simplified.

  An embodiment for carrying out the present invention will be described below with reference to FIGS. First, an overall configuration of a glove box 2 of an automobile 1 according to an embodiment of the present invention will be described with reference to FIGS. In the following description, "car 1", "instrument panel 10", and "grab door 20" will be described as examples of "vehicle", "interior member", and "lid". In the following description, the terms upper, lower, front, rear, left, and right refer to the directions of upper, lower, front, rear, left, and right, that is, the direction of the automobile 1 described in the above-described drawings. The upper, lower, front, rear, left, and right directions are shown.

  The glove box 2 mainly includes a glove door 20 and a lock mechanism 50. Hereinafter, the grab door 20 and the lock mechanism 50 will be individually described (see FIG. 1).

  First, the grab door 20 will be described. The grab door 20 is formed of a lid member hinged to the instrument panel 10 so as to open and close a substantially rectangular opening 12 formed on the instrument panel 10 of the automobile 1 opposite to a passenger seat (not shown). . The left and right inner walls 12a of the opening 12 of the instrument panel 10 can be engaged with an engagement portion 62 of a rod 60 of a lock mechanism 50 and an engagement portion 72 of a ratchet 70 of the lock mechanism 50 described later. Concave holes (engaged portions) 12b are respectively formed (see FIG. 2).

  The grab door 20 is formed of the lid member as described above, and has a substantially rectangular door outer 30 corresponding to the opening 12 of the instrument panel 10, and a door inner 40 assembled to an inner surface (anti-design surface) of the door outer 30. (See FIGS. 3, 4, and 6). The outer surface of the door outer 30 is a design surface that is integrated with the design surface of the instrument panel 10. An opening 30a is formed at the upper right of the door outer 30 so as to penetrate its thickness.

  A base 32 having a concave portion 32a is attached to the door outer 30 so as to cover the opening 30a. An opening 32b is also formed in the recess 32a so as to penetrate the plate thickness. A knob 34 is pivotally attached to the concave portion 32a of the base 32 via a rotating shaft 34a whose substantially vertical direction forms an axial direction. At this time, a torsion spring 34b is hung between the base 32 and the knob 34. Thereby, the knob 34 can always be urged to the state before the pulling operation.

  On the inner surface of the knob 34, a projection 34c is formed which protrudes forward through an opening 32b of the base 32. On the left side of the inner surface of the door outer 30, a guide 36 having a bearing 36a capable of receiving a rotation shaft 74 of a ratchet 70 of the lock mechanism 50 described later is formed. On the right side of the inner surface of the door outer 30, a guide 38 having a through hole 38a into which a distal end of a rod 60 described later can be inserted is formed.

  On the other hand, a storage box 42 that can store small items (not shown) such as gloves is formed on the inner surface of the door inner 40. In the left and right edges of the door inner 40, through holes 44 are formed to advance and retreat an engaging portion 62 of a rod 60 of a lock mechanism 50 described later and an engaging portion 72 of a ratchet 70 of the lock mechanism 50 described later. ing. On the outer surface of the door inner 40, a grid-like rib 46 for increasing the rigidity of the door inner 40 is formed. The door inner 40 is mounted on the inner surface of the door outer 30 so as to sandwich a lock mechanism 50 described later.

  Next, the lock mechanism 50 will be described. The lock mechanism 50 mainly includes a rod 60 and a ratchet 70 (see FIGS. 5 and 7). The distal end of the rod 60 forms an engaging portion 62 with the concave hole 12b of the inner wall 12a on the right side of the opening 12 of the instrument panel 10 described above. The engaging portion 62 is formed with an inclined surface 62a such that when the engaging portion 62 itself interferes with the edge 12c of the opening 12, the rod 60 slides (retreats) to the left.

  The proximal end of the rod 60 is a holding portion 64 having a long hole 64a that can hold a holding shaft 76 of a ratchet 70 of the lock mechanism 50 described later. Further, a first through hole 66 having an inner wall 66a is formed on the distal end side of the rod 60. A second through hole 68 having an inner wall 68a having a cam surface is formed on the proximal end side of the rod 60. The distal end side of the rod 60 thus formed is inserted into the through hole 38a of the guide 38 on the right side of the door outer 30.

  On the other hand, the ratchet 70 has an engaging portion 72 formed in the concave hole 12b of the inner wall 12a on the left side of the opening 12 of the instrument panel 10 described above. The ratchet 70 has a rotating shaft 74 that can be received by the bearing 36 a of the guide 36 of the door outer 30, a held shaft 76 that can hold the holding portion 64 of the rod 60, and a second through hole 68 of the rod 60. And a pin 78 that can be pressed against the inner wall 68a of the second member.

  The ratchet 70 thus formed is pivotally mounted on the bearing of the guide 36 of the door outer 30 via the rotating shaft 74 in a state where the pinched shaft 76 is pinched by the pinching portion 64 of the rod 60. Thus, when the rod 60 is slid to the left with respect to the door outer 30, the ratchet 70 can be rotated in the reverse direction with respect to the door outer 30 by the holding of the holding portion 64.

  When the rod 60 slid to the left is returned to the state before the slide (slid to the right), the ratchet 70 can be rotated with respect to the door outer 30 by pressing the inner wall 68a. At this time, a tension spring 30b is hung between the door outer 30 and the rod 60. Thus, the door outer 30 can always be urged to a state before the operation (before the operation of sliding to the left). The glove box 2 and the lock mechanism 50 constitute the glove box 2.

  Next, an operation of the glove box 2 having the above-described configuration will be described with reference to FIGS. In this description, a description will be given from the time when the grab door 20 is in the closed state in which the opening 12 of the instrument panel 10 is closed as shown in FIG. In the closed state of the grab door 20, the lock mechanism 50 is also in the locked state, as is clear from FIG.

  The locked state of the lock mechanism 50 is a state where the rod 60 and the ratchet 70 are engaged with each other. That is, the engagement state of the rod 60 means that the engagement part 62 of the rod 60 advances from the through hole 44 on the right side of the door inner 40, and the engagement part 62 of the advanced rod 60 is on the right side of the instrument panel 10. This is a state of engagement with the concave hole 12b. The engagement state of the ratchet 70 means that the engagement part 72 of the ratchet 70 advances from the through hole 44 on the left side of the door inner 40, and the engagement part 72 of the ratchet 70 advances to the left side of the instrument panel 10. This is a state of engagement with the concave hole 12b.

  First, the operation of opening the glove door 20 in the closed state will be described. First, from the state shown in FIG. 8, the knob 34 of the grab door 20 is pulled against the urging force of the torsion spring 34b (see FIG. 9). Then, as shown in FIG. 9, the protrusion 34 c of the knob 34 presses the inner wall 66 a of the first through hole 66 of the rod 60. As a result, the rod 60 slides to the left against the urging force of the tension spring 30b.

  Therefore, the engagement of the engaging portion 62 of the rod 60 with the concave hole 12b on the right side of the instrument panel 10 is released. At this time, the holding portion 64 of the rod 60 slid to the left pushes the held shaft 76 of the ratchet 70. Thereby, the ratchet 70 rotates in the reverse direction so that the engagement of the engaging portion 72 of the ratchet 70 with the concave hole 12b on the left side of the instrument panel 10 is released. The locking mechanism 50 switches to the unlocked state by the sliding of the rod 60 and the reverse rotation of the ratchet 70.

  The unlocked state of the lock mechanism 50 is a state in which the engagement between the rod 60 and the ratchet 70 has been released. That is, the state where the engagement of the rod 60 is released means that the engagement portion 62 of the rod 60 is released from engagement with the concave hole 12b on the right side of the instrument panel 10 and the rod is released. 60 is a state in which the engaging portion 62 has retreated into the through hole 44 on the right side of the door inner 40.

  The state in which the engagement of the ratchet 70 is released means that the engagement portion 72 of the ratchet 70 is released from engagement with the concave hole 12b on the left side of the instrument panel 10, and the ratchet 70 in which the engagement is released 70 is a state in which the engaging portion 72 has retreated to the through hole 44 on the left side of the door inner 40. When the lock mechanism 50 is switched to the unlocked state in this manner, the glove door 20 can be opened in the open state in which the opening 12 of the instrument panel 10 is open as in the related art. Therefore, small items can be stored in the storage box 42 provided on the inner surface of the opened glove door 20 (see FIG. 10).

  When the operation of pulling the knob 34 is canceled, the knob 34 is returned to the state before the operation by the restoring force of the torsion spring 34b. Then, the pressing of the protrusion 34c of the knob 34 against the inner wall 66a of the first through hole 66 of the rod 60 is released, so that the rod 60 is returned to the state before sliding by the restoring force of the extension spring 30b. Therefore, the engaging portion 62 of the rod 60 is also returned to the state in which it has advanced from the through hole 44 on the right side of the door inner 40. At this time, the inner wall 68a of the second through hole 68 of the rod 60 returned to the state before the slide presses the pin 78 of the ratchet 70. Therefore, the ratchet 70 rotates so that the engagement portion 72 of the ratchet 70 is also returned to the state in which it has advanced from the through hole 44 of the door inner 40.

  Next, an operation of closing the glove door 20 in the open state will be described. First, the glove door 20 is closed from the state shown in FIG. 10 so as to return to the closed state in which the opening 12 of the instrument panel 10 is closed. Then, as shown in FIG. 11, the inclined surface 62 a of the engaging portion 62 of the rod 60 interferes with the edge 12 c of the opening 12 of the instrument panel 10. From the state shown in FIG. 11, an operation of further closing the grab door 20 is performed.

  Then, the rod 60 that interferes with the sloping surface 62a of the engaging portion 62 at the edge 12c of the opening 12 of the instrument panel 10 slides to the left against the urging force of the tension spring 30b. At this time, the holding portion 64 of the rod 60 slid to the left pushes the held shaft 76 of the ratchet 70. As a result, the ratchet 70 rotates in the reverse direction in a direction in which the engagement of the engagement portion 72 of the ratchet 70 is released (see FIG. 11).

  From the state shown in FIG. 11, an operation of further closing the grab door 20 is performed (see FIG. 12). Then, the inclined surface 62 a of the engaging portion 62 of the rod 60 gets over the edge 12 c of the opening 12 of the instrument panel 10. As a result, the grab door 20 is returned to the closed state in which the opening 12 of the instrument panel 10 is closed (see FIG. 8). In addition, the rod 60 is returned to the state before the slide by the restoring force of the tension spring 30b due to the overriding. Therefore, the rod 60 is also returned to the engaged state (a state in which the engaging portion 62 of the rod 60 is engaged with the concave hole 12b on the right side of the instrument panel 10).

  At this time, the inner wall 68a of the second through hole 68 of the rod 60 returned to the state before the slide presses the pin 78 of the ratchet 70. Therefore, the ratchet 70 rotates so that the engaging portion 72 of the ratchet 70 advances from the through hole 44 on the left side of the door inner 40. Accordingly, since the ratchet 70 is also returned to the state before the reverse rotation, the ratchet 70 is also brought into the engaged state (the engaging portion 72 of the ratchet 70 is engaged with the concave hole 12b on the left side of the instrument panel 10). Will be returned. Thus, the lock mechanism 50 is also returned to the locked state.

  The glove box 2 according to the embodiment of the present invention is configured as described above. According to this configuration, the locking of the lock mechanism 50 of the glove door 20 of the glove box 2 is performed by the engagement of the rod 60 and the engagement of the ratchet 70. The engagement of the ratchet 70 follows the engagement of the rod 60, and is performed by the rotation of the ratchet 70. Therefore, as described in the related art, by performing an operation of closing the opening 12 of the instrument panel 10 at the right end of the grab door 20, the engaging portion 62 of the rod 60 is recessed before the engaging portion 72 of the ratchet 70. Even if it engages with the hole 12b, unlike the related art, the position shift occurring on the side (left side) where the closing operation is not performed can be absorbed by the rotation of the ratchet 70. Therefore, the engagement portion 72 of the ratchet 70 is engaged following the engagement of the engagement portion 62 of the rod 60. As a result, the lock mechanism 50 does not enter the one-sided state (the state where only the right side is engaged).

  Even when the operation of closing the opening 12 of the instrument panel 10 at the left end of the glove door 20 is performed, the engaging portion 62 of the rod 60 precedes the engaging portion 72 of the ratchet 70 in the same manner as described above. It will engage with hole 12b. Therefore, similarly to the above description, the displacement occurring on the side where the closing operation is not performed (left side) can be absorbed by the rotation of the ratchet 70. Therefore, the engagement portion 72 of the ratchet 70 is engaged following the engagement of the engagement portion 62 of the rod 60. As a result, the lock mechanism 50 does not enter the one-sided state (the state where only the right side is engaged).

  Further, since the number of parts of the lock mechanism 50 is two (the rod 60 and the ratchet 70), it is compared with the lock mechanism 150 of the related art in which the number of parts is three (a pair of the rods 160 and 170 and the link member 180). Thus, the number of parts can be reduced.

  Further, according to this configuration, the ratchet 70 can be rotated in the reverse direction so that the engagement of the engagement portion 72 of the ratchet 70 follows the release of the engagement of the engagement portion 62 of the rod 60. I have. Therefore, the structure of the lock mechanism 50 can be simplified.

  The above description relates only to an embodiment of the present invention, and does not mean that the present invention is limited to the above content.

  In the embodiment, the mode in which the lock mechanism 50 is unlocked by the operation of pulling the knob 34 has been described. However, the present invention is not limited to this, and any type of knob 34 such as an operation of pressing the knob 34 and an operation of sliding the knob 34 may be used.

  Further, in the embodiment, as examples of the “vehicle”, the “interior member”, and the “lid”, the “automobile 1”, the “instrument panel 10”, and the “grab door 20” have been described. However, the present invention is not limited to this. “Vehicle” is “various vehicles (for example, trucks, etc.)”, “Interior member” is “various boxes (for example, console boxes, etc.)”, and “ The lid may be a lid of various boxes (for example, a lid of a console box).

  In the embodiment, the storage box 42 capable of storing small items is described as being formed on the inner surface of the door inner 40. However, the present invention is not limited to this, and the storage box 42 that can store small items may be formed in the opening 12 of the instrument panel 10. In that case, the door inner 40 may simply be a panel member forming the inside of the grab door 20.
