Description

  The present invention relates to an opening / closing body locking device for locking an opening / closing body attached to an opening of a fixed body so as to be openable / closable in a closed state.

  For example, an opening / closing body such as a lid is detachably attached to an opening formed in a fixed body such as a glove box of an automobile. A locking device is provided for locking the opening to a closed state with a lid or the like and opening the lid or the like from the opening.

  As such a locking device, for example, a pair of rods slidably installed on a lid attached to the opening so as to be openable and closable, and a direction in which the tip portions of both rods protrude toward the concave portion of the inner surface of the opening There is known one having a return spring that urges the spring. However, in this locking device, when the lid is closed, the tip of the rod comes into contact with the inner peripheral surface of the opening, and hitting sound at that time sometimes becomes a problem.

  In order to solve the above problem, the following Patent Document 1 discloses an opening / closing member, a recess provided in an interior member, a pair of left and right rods entering and exiting the recess, and urging the tip of these rods toward the recess. A return spring, a pin for preventing the rod from returning when a pair of rods are pushed out of the recesses and the opening and closing member is opened against the biasing force of the return spring, and a pin for biasing the pin A vehicle storage device having an urging spring is described.

  Each of the pair of rods has a rack groove formed at a base end portion thereof, and a gear meshes with the groove, and the pair of rods slide in synchronization with each other in opposite directions via the gear. In the middle of one of the rods, there is a protruding portion that is engaged with a cylindrical portion provided on the pin. A tension spring-like return spring is attached to the other rod, and its tip is biased toward the recess, and the tip of one rod is also biased toward the recess via the gear. Yes. A push-type knob is disposed on the interior member side.

  When the knobs are pushed in with the ends of the pair of rods fitted into the recesses of the interior member and the opening is closed by the closing member, the tips of one of the rods are pressed against the urging force of the return spring. Then, the rod is pulled inward of the opening / closing member, and the other rod is also pulled in synchronism with this, and the leading ends of both rods are removed from the recesses to open the opening / closing member.

  At this time, the pair of rods are pushed outward by the urging force of the return spring, but the convex portion of one rod is engaged with the cylindrical portion of the pin base, and the tip of one rod The amount of protrusion to the outside of the rod is restricted, and the amount of protrusion to the outside of the tip of the other rod is also restricted via the gear, so the rod tip and the interior member inner surface when closing the opening and closing member Is reduced, and the sliding sound is reduced.

Thus, the stopper 60 is slidably assembled to the base member 20 while the stopper 60 is normally biased toward the rear of the base member by the biasing force of the stopper spring 16 (FIG. 2). reference).

  As described above, in a state where the stopper 60 is slid to the rear side of the base member, the base portion 61 is disposed on the rotation locus of the arm portion 43 of the rotating body 40 and is engaged with the side surface 43a of the arm portion 43 of the rotating body 40. On the other hand, when the stopper 60 slides to the front side of the base member against the urging force of the stopper spring 16, the base portion 61 moves away from the rotation locus of the arm portion 43 and rotates. It comes off from the side surface 43a of the arm part 43 of the body 40 (refer FIG.6 and FIG.8).

  In relation to the stopper 60, operations of the rotating body 40 and the link rods 70 and 71 will be described.

  That is, the operating member 50 is pushed into the base member 20, the rotating body 40 is rotated in the direction of arrow A2 in FIG. 12B against the urging force of the torsion spring 12, and the hook portions 73 of the link rods 70 and 71 are rotated. , 73 are slid to a position where they do not engage with the lock portions 3, 3 of the glove box 1, and when the lid 5 is rotated in the opening direction, the stopper 60 biased by the stopper spring 16 slides to the rear side of the base member. Then, the base portion 61 engages with the side surface 43a of one arm portion 43 of the rotating body 40 (see FIGS. 9 to 11). As a result, the rotation of the rotating body 40 is restricted, and the hook parts 73 and 73 of the link rods 70 and 71 are restricted from returning in the direction in which they engage with the lock parts 3 and 3. In this embodiment, the hook portions 73 and 73 of the link rods 70 and 71 are held in a state where they are not engaged with the lock portions 3 and 3 (see FIG. 13).

  On the other hand, when the opening 2 of the glove box 1 is closed with the lid 5 in the above state, the tip 63 of the stopper 60 is pressed by the pressing protrusion 4 (see FIG. 2) around the opening 2, and the biasing force of the spring 16 for stopper is pressed. Against this, the stopper 60 slides to the front side of the base member, and the base portion 61 moves away from the side surface 43a of the arm portion 43 of the rotating body 40, and the engagement with the rotating body 40 is released (see FIGS. 6 to 8). ). As a result, the rotation of the rotator 40 is permitted, and the torsion spring 12 again urges the rotator 40 to rotate in the direction of the arrow A1 in FIG. 3 (see FIG. 12).

  Next, the effect of the locking device 10 composed of the above-described components will be described.

  As shown in FIGS. 12A and 12B, in a state where the opening 2 of the glove box 1 is closed by the lid 5, the stopper 60 slides to the front side of the base member, and the base 61 and the rotating body 40 are The engagement with the arm portion 43 is released (see FIGS. 6 to 8), and the torsion spring 12 urges the rotating body 40 to rotate in the direction of the arrow A1 in FIG. However, it is in the state engaged with the lock parts 3 and 3 of the glove box 1. Further, the base 61 of the stopper 60 is held in contact with the front surface 43b of the arm portion 43 of the rotating body 40 (see FIGS. 6 and 8).

  When the lid 5 is opened from the opening 2 of the glove box 1 in this state, the operating member 50 is pushed into the base member 20 against the urging force of the operating member spring 14. Then, each cam projection 45 of the rotating body 40 is pressed by the cam inclined surface 55a of each wall portion 55 of the operation member 50, and the cam projection 45 slides on the cam inclined surface 55a and is also attached to the base 61 of the stopper 60. While the front surface 43b of the arm portion 43 is in sliding contact with the rotational biasing force of the torsion spring 12, the rotating body 40 rotates in the direction of arrow A2 in FIG.

  When the rotating body 40 rotates until the front surface 43b of the arm portion 43 is separated from the base portion 61 of the stopper 60, the stopper 60 is urged by the stopper spring 16 as shown in FIGS. And the base portion 61 engages with the side surface 43a of the arm portion 43 of the rotating body 40 to restrict the rotation of the rotating body 40. Therefore, the hook portions 73 and 73 of the link rods 70 and 71 are connected to the lock portion 3. , 3 is controlled so that the hook portions 73, 73 are not engaged with the lock portions 3, 3 (see FIG. 13), and the lid 5 is opened from the opening 2 of the glove box 1. Can be moved to open the opening 2.

  Thereafter, when the lid 5 is pushed in to close the opening 2 of the glove box 1 again, the tip 63 of the stopper 60 is pressed by the pressing protrusion 4 (see FIG. 2) on the opening 2 side. Since the stopper 60 slides to the front side of the base member against the urging force of the spring 16, the base portion 61 is separated from the side surface 43 a of the arm portion 43 of the rotating body 40 and the engagement with the rotating body 40 is released. (See FIGS. 6 to 8) The rotating body 40 is again urged to rotate in the direction of arrow A1 in FIG. 7 by the torsion spring 12, and the hook portions 73 and 73 of the link rods 70 and 71 are engaged with the lock portions 3 and 3, respectively. And the opening part 2 of the glove box 1 can be locked in the state closed with the lid 5 (refer FIG. 12).

  At this time, as shown in FIGS. 9 to 11, the base portion 61 of the stopper 60 is engaged with the side surface 43 a of the arm portion 43 of the rotating body 40, so that the rotation of the rotating body 40 is restricted. Since the return of the hook portions 73 and 73 to the lock portion 3 is restricted and the hook portions 73 and 73 are held in a state where they are not engaged with the lock portions 3 and 3, When the lid 5 is pushed in, the hook portions 73 and 73 of the link rods 70 and 71 are prevented from slidingly contacting the inner peripheral surfaces on both sides of the opening 2, and the lid 5 can be closed smoothly without resistance. At the same time, the hitting sound can be reduced.

  The locking device 10 is configured to restrict the rotational operation of the rotating body 40 by engaging the stopper 60 with the rotating body 40 or releasing the engagement with the rotating body 40. When the stopper 60 is engaged with the rotating body 40, the hook portions 73, 73 of the pair of link rods 70, 71 interlocking with the rotating body 40 can be pulled evenly into the lock portions 3, 3. On the other hand, when the engagement between the stopper 60 and the rotating body 40 is released, the hook portions 73, 73 of the link rods 70, 71 can be projected evenly. As a result, the left and right variations in the pull-in amount and the protrusion amount of the hook portions 73, 73 of the pair of link rods 70, 71 can be suppressed, so that the hook portion 73 of either one of the link rods has an opening portion. It is possible to prevent the lid 5 from being caught on the inner periphery of the belt 2, and to close the lid 5 smoothly, thereby improving the operability.

  Further, in this embodiment, the base portions of the pair of link rods 70 and 71 are pivotally attached to the arm portions 43 and 43 extending from the rotating body 40, and the side surface 43 a is utilized by using the arm portions 43. Since the rotation of the rotating body 40 is restricted by engaging the stopper 60 with the rotating body 40, it is not necessary to provide a portion where the stopper 60 is engaged with the rotating body 40. The rotating body 40 has a simple structure. Can be.

  Further, in this embodiment, the rotating body 40 and the stopper 60 are assembled to the common base member 20 attached to the lid 5, so that the rotating body 40 and the stopper 60 are integrated with the base member 20. As a result, the assembly workability can be improved and the space can be saved.
