  Therefore, in the first aspect of the present invention, an operation handle that pivots from the top to the bottom is pivotally supported on the upper edge of the door of the storage body, and a finger is inserted into a position corresponding to the operation handle of the support body. Since there is no unnecessary protruding part inside the storage body as in the past, there is no need to worry about hindering access to small items, and the internal space of the storage body is made effective. It can be used. In addition, because the link member and the lever member constituting the lever mechanism are switched between the sliding contact state and the non-sliding contact state, both the locking device having the key cylinder lock and the locking device having no key cylinder lock are used. Since it can be applied, it will be rational.

  In the invention according to claim 2, the link member and the lever member can be easily switched between the sliding contact state and the non-sliding contact state. In the invention according to claim 3, the guide piece prevents the tip end portion of the lever member from being deformed and falling off from the sliding contact portion with the link member in the sliding contact state between the link member and the lever member.

Hereinafter, if the present invention is described in detail based on a preferred embodiment illustrated in the drawings, the locking device according to the embodiment also includes a glove box B which is attached to an instrument panel P of an automobile so as to be opened and closed as shown in FIG. It was developed as an object, and the feature thereof is that an operation handle 2 that rotates from top to bottom is provided at the upper edge of the glove door Ba of the glove box B that is a storage body, and the instrument panel P that is a support body is provided. By depressing a portion corresponding to the operation handle 2 and defining an operation space 31 into which a finger is inserted, and turning the operation handle 2 from top to bottom using the operation space 31, The glove box B can be unlocked. Accordingly, it is not necessary to provide the operation space 31 for inserting a finger on the side of the glove box B, and a portion protruding inside the glove box B can be eliminated. Can be eliminated. Moreover, the dead space inside the glove box B generated due to the presence of the protruding portion can be eliminated.

Therefore, this will be described in detail. As shown in FIG. 1, the locking device according to the present embodiment includes a case 1 screwed from the back side to the center of the upper edge of the globe door Ba shown in FIG. An operation handle 2 that is pivotally supported by the case 1 so as to rotate from top to bottom, and a striker 32 (see FIG. 13) that is supported by the case 1 so as to be movable up and down and provided on the instrument panel P side. The lock body 3 to be removed, the compression coil spring 4 as a first biasing member for biasing the lock body 3 in a direction to engage the striker 32, and the case 1 so as to be pivotally supported by the case 1. A link member 5 that is rotated by a rotation operation, a torsion coil spring 6 that is a second urging member that urges the distal end portion 5b of the link member 5 to the upper side of the case 1, and a shaft that is rotatable to the case 1 It is supported to turn the tip 5b of the link member 5. Flip and has a configuration and a lever member 7 is lowered against the locking body 3 in the urging spring pressure of the compression coil spring 4. still. The lever member 7 and the link member 5 constitute a lever mechanism that connects the operation handle 2 and the lock body 3.

Further, the upper surface of the distal end portion 7b of the lever member 7 and the distal end portion 5b of the link member 5 are brought into sliding contact with each other, and the lower surface of the distal end portion 7b of the lever member 7 and the upper surface of the engaging portion 19 of the lock body 3 (see FIG. 3). Are slidably contacted to form a three-way slidable contact portion that transmits the force from the operation handle 2 to the lever member 7 and the lock body 3 via the link member 5. In the three-way sliding contact portion, the force from the operation handle 2 is simultaneously transmitted to the lever member 7 and the lock body 3 through the link member 5 at one place. Since the magnitude of the force that can be transmitted is proportional to the area of the portion where each member is in sliding contact, a certain amount of area is required. By adopting a configuration in which the link member 5, the lever member 7, and the engaging portion 19 of the lock body 3 are slidably contacted in a stacked state, the two slidable contact portions can be consolidated in one place, so that the device itself can be reduced in size. Maintenance is also easy.

As shown in FIG. 2, the case 1 is formed with a storage chamber 8 that supports the lock body 3 and the compression coil spring 4 at the center thereof, and a pair of the striker 32 that receives the striker 32 above the storage chamber 8. A cylindrical wall 10 having a structure in which a key cylinder lock can be mounted inside is integrally connected to a side portion of the receiving wall 9, and a bottom portion of the cylindrical wall 10 is formed. A first shaft 11 that serves as a pivot point of the lever member 7 and a second shaft 12 that guides the rotation are formed on the back surface side, and each of the operation handles 2 described later is provided on both sides of the front surface of the storage chamber 8. A pair of shaft portions 13 that are fitted to the bearing portions 16 are formed, and a third shaft 14 that serves as a rotation fulcrum of the link member 5 is formed on the lower surface of the opposite side of the cylindrical wall 10. . In addition, the front side of the storage chamber 8 is opened over the entire area, and by using the opening 15, the engagement portion 19 of the lock body 3 described later can be moved.

Further, the case 1 has an operation handle 2 on the front side thereof, and is fixed to the globe door Ba on the back side, and the lock body 3 appears and disappears from the upper side. The storage chamber 8 is a rectangular bottomed hole that is opened from the upper side to the lower side of the case 1, and has a guide groove in the vertical direction that serves as a guide when the lock body 3 slides up and down. A surface that supports one end of the compression coil spring 4 and a protrusion that is inserted inside the compression coil spring 4 and serves as a guide during expansion and contraction. The receiving wall 9 has a horizontal U-shape and has an opening in the lateral direction. The lock body 3 is received from below so as to close the opening, and the receiving wall 9 and the lock body 3 cooperate to define a space. It is the composition to do.

The cylindrical wall 10 is formed from the front side to the back side of the case 1 and has a recess having substantially the same size and shape as the outer shape of a key cylinder lock 34 described later. The bottom surface of the concave portion is on the back side of the case 1, and the first shaft 11 and the second shaft 12 projecting in the axial direction of the cylindrical wall 10 from the bottom surface of the concave portion toward the back side of the case 1 are spaced substantially horizontally. The tip of the first shaft 11 is L-shaped to prevent the lever member 7 from falling off after mounting, and the second shaft 12 is a columnar protrusion shorter than the first shaft 11 and will be described later. It has substantially the same size and shape as the eccentric shaft 35 of the key cylinder lock 34. The two shaft portions 13 are on the front side of the case 1, and are arranged substantially horizontally with a gap between the sliding center shafts of the lock body 3.

The third shaft 14 is on the front side of the case 1 and is on the opposite side of the cylindrical wall 10 with respect to the sliding central axis of the lock body 3, and the center of the third shaft 14, the three-way sliding portion, and the concave portion of the cylindrical wall 10. The bottom center of the is aligned in a line. Between the third shaft 14 and the case 1, there is a cylindrical portion around which the torsion coil spring 6 is wound. The cylindrical portion is concentric with the third shaft 14 and has a larger outer shape than the third shaft 14. An annular groove is formed at the base of the cylindrical portion, and a part of the wound torsion coil spring 6 is accommodated. The groove is provided with a notch portion in which a part of the outer wall is notched in order to hook one end of the torsion coil spring 6.

Further, the storage chamber 8 has an opening 15 on the front side of the case 1 at the lower portion thereof, and an opening penetrating from the front side of the case 1 to the back side is provided between the storage chamber 8 and the cylindrical wall 10. Since the lever member 7 is disposed through the opening, one end of the lever member 7 is on the front side of the case 1 and the other end is on the back side of the case 1.

The operation handle 2 is formed with a pair of bearing portions 16 for fitting the shaft portion 13 on the lower side of the back surface thereof, and an operating claw 17 engaged with a connecting hole 21 of a link member 5 described later at one end portion. The safety plate 18 is continuously formed along the width region on the upper surface of the back surface. The operation handle 2 has a back surface and a design surface that face the case 1, covers the two shaft portions 13 and the concave opening inside the cylindrical wall 10, and extends beyond the upper surface of the case 1. . The pair of bearing portions 16 protrude from the lower portion of the operation handle 2 at positions where they are fitted with the two shaft portions 13. The actuating claw 17 protrudes between the pair of bearing portions 16 and the side portion constituting the contour of the design surface of the operation handle 2, and the tip thereof has a hook shape. In addition to being extended to the case 1 side, it extends to the lower side of the case 1 beyond the bearing portion 16. Further, since the inside of the hook-shaped portion at the tip of the operating claw 17 has a fillet, when the operating claw 17 engages and slides on the edge of the connecting hole 21 of the link member 5 described later, the sliding The moving operation can be performed smoothly.

Further, there is a ridge between the upper part constituting the contour of the design surface of the operation handle 2 and the safety plate 18 on which the operator hooks a finger. Therefore, the hooked operator's finger is not slipped off by the protrusion provided along the upper edge of the back surface of the operation handle 2. Since the safety plate 18 covers the upper part of the locking device, even if the operator hooks a finger, the finger does not cross the safety plate 18 and contact other parts of the locking device. Further, it is possible to prevent foreign matter or the like from entering from the upper surface of the locking device or foreign matter adhering to the finger from entering the locking device due to gravity.

As shown in FIG. 3, the lock body 3 is urged in the direction of engaging with the striker 32 by the urging spring pressure of the compression coil spring 4 as described above. The engaging portion 19 that faces outward from the opening 15 of the storage chamber 8 is integrally formed, and the link member 5 is rotated by the rotation operation of the operation handle 2, so that the distal end portion 7 b of the lever member 7 is rotated. Then, by pressing the engaging portion 19, the lock body 3 is lowered and the engagement with the striker 32 is released. In addition, the lock body 3 has a columnar shape having substantially the same cross-sectional shape as the hole shape of the storage chamber 8 on the case 1 side, the slope 3a is formed at the upper end in the longitudinal direction, and the engaging portion 19 is formed at the lower end. In addition, a protrusion that fits in the guide groove of the storage chamber 8 is provided in the longitudinal direction.

As shown in FIG. 4, the link member 5 constituting the lever mechanism is formed with a third insertion hole 20 into which the third shaft 14 is inserted into the triangular substrate 5a, and the operation handle on the side thereof. The connecting hole 21 for engaging the two operating claws 17 is formed, while the tip end portion 5b is extended in a bowl shape, and the tip end lower surface 22 of the tip end thick portion of the lever member 7 to be described later via the guide piece 23 It is configured to be in sliding contact with the upper surface of 28. When the link member 5 is pivotally supported on the third shaft 14, the torsion coil spring 6 is attached at the same time, and the distal end portion 5 b is biased upward of the case 1. Accordingly, since the link member 5 always tries to rotate counterclockwise, the operation handle 2 that engages the operating claw 17 with the connecting hole 21 of the link member 5 is not unintentionally rattled. The guide pins 24 are in sliding contact with the surface facing the case 1 to guide the rotation of the link member 5.

The upper edge of the connecting hole 21 is a straight line portion that is horizontal at the normal position, and the surface facing the operation handle 2 is chamfered. The fillet portion of the operating claw 17 of the operation handle 2 is in sliding contact with the chamfered portion of the upper edge. The third insertion hole 20 is provided in the lower part of the substrate 5a, the connection hole 21 is provided in line with a substantially horizontal position of the third insertion hole 20, and the third insertion hole 20 is sandwiched between the distal end portion 5b. On the other side. In order to secure a space for mounting the torsion coil spring 6 between the substrate 5a of the link member 5 and the case 1, the connecting portion between the substrate 5a and the tip 5b has a crank shape bent in the thickness direction. The top 5b is connected to the top of the substrate 5a.

The guide piece 23 prevents the tip portion 7b of the lever member 7 from being deformed and falling off from the sliding contact portion with the link member 5, and uses a key cylinder lock 34 as will be described later. When the lever member 7 is switched from the non-sliding contact state to the sliding contact state, the lever member 7 has a function of guiding the upper surface of the thick wall 28 so that it smoothly matches the lower surface of the tip portion 5b of the link member 5. Fulfill. One end of the torsion coil spring 6 is hooked on the connecting portion between the substrate 5a and the tip portion 5b, and the other end is hooked on the case 1 to urge the link member 5 counterclockwise. Since the link member 5 is always urged counterclockwise by the torsion coil spring 6, the operating claw 17 of the operation handle 2 engaged with the upper edge of the connecting hole 21 is located below the case 1. Since the back surface of the operation handle 2 comes into contact with the front surface of the case 1, the operation handle 2 is always pressed against the case 1 and does not rattle.

When the fillet portion of the operating claw 17 is brought into sliding contact with the upper edge of the connection hole 21 by the rotation of the operation handle 2, the operating claw 17 presses the substrate 5a in the direction approaching the case 1, but the guide pin Since 24 is in sliding contact with the surface facing the case 1 and the distance between the link member 5 and the case 1 is kept constant, the tip 5b of the link member 5 can also keep the distance from the case 1 constant. Accordingly, the distal end portion 5b of the link member 5 does not fall off from the sliding contact portion with the lever member 7, and the guide pin 24 prevents the link member 5 from dropping off.

Similarly, as shown in FIG. 5, the lever member 7 constituting the lever mechanism is a long hole-shaped first member with an elastic piece 25 into which the first shaft 11 of the case 1 is fitted into the rhomboid substrate 7 a. The insertion hole 26 and the elongated second insertion hole 27 into which the second shaft 12 is inserted are formed, and the front end portion 7b is once bent laterally from one end portion side of the substrate 7a and then formed into a bowl shape. A thick wall 28 and a thin wall 29 are continuously formed at the distal end portion 7b so that the lower end surface 22 of the link member 5 slides on the upper surface of the thick wall 28. . Therefore, in terms of arrangement, the distal end portion 5b of the link member 5, the distal end portion 7b of the lever member 7, and the engaging portion 19 of the lock body 3 are arranged in order from the top. The sliding contact portion 19 can be made thin, and when the operation handle 2 is rotated, the link member 5 rotates in the direction opposite to the urging direction, that is, clockwise, and at the same time the lever member 7 rotates counterclockwise. Thus, the engaging portion 19 of the lock body 3 is lowered against the spring pressure of the compression coil spring 4.

Further, the connecting portion between the substrate 7a and the tip portion 7b of the lever member 7 has a crank shape bent in the thickness direction, and is connected to the tip portion 7b at the lower portion of the substrate 7a. When the lever member 7 is attached to the case 1, the connecting portion between the substrate 7 a and the tip 7 b is located between the cylindrical wall 10 of the case 1 and the storage chamber 8 and is disposed in an opening that penetrates from the front side to the back side of the case 1. Then, when it exhibits a crank shape, the tip 7 b of the lever member 7 is arranged on the front side of the case 1, and the substrate 7 a is arranged on the back side of the case 1. Since the lever member 7 is connected to the three-way sliding portion and the second shaft 12 of the case 1 or the eccentric shaft 35 of the key cylinder lock 34 described later, when the lever member 7 is arranged on the front side of the case 1, The bottom surface of the concave portion of the cylindrical wall 10 in which the two shafts 12 are formed or the rear end surface of the key cylinder lock 34 having the eccentric shaft 35 must be disposed on the front side of the case 1. Therefore, the lever member 7 is configured to connect the front side and the back side of the case 1, so that the key cylinder lock 34 can be attached to the back side of the case 1 without the cylindrical wall 10 and the key cylinder lock 34 projecting from the front side of the case 1. Therefore, the entire locking device can be made thin.

In the normal state, the first insertion hole 26 is composed of two elongated holes extending in a substantially horizontal direction and arranged vertically, and a groove connecting the two elongated holes in the vicinity of the end thereof. Are formed with different widths to prevent erroneous assembly. The width of the lower long hole is substantially the same as the diameter of the first shaft 11, and the width of the upper long hole is smaller than that, so the first shaft 11 can be fitted only with the lower long hole. It has become. The elastic piece 25 surrounded by the two long holes and the groove has such a length that sufficient elastic deformation can be obtained to smoothly insert the first shaft 11 having an L-shaped tip into the lower long hole. Yes. The tip of the elastic piece 25 has a bulge, and the first shaft 11 of the case 1 is fitted into the long hole below the first insertion hole 26, and the end of the long hole is formed by the bulge of the tip of the elastic piece 25. Restrained by

When the tip of the first shaft 11 having an L shape is pushed into the lower long hole in the first insertion hole 26, the shape of the long hole is deformed by the elastic deformation of the elastic piece 25 so as to receive the L shape. Since the first shaft 11 is fitted into the first insertion hole 26, the L-shaped tip of the first shaft 11 prevents the lever member 7 from falling off. After the first shaft 11 is fitted into the first insertion hole 26, the elastic piece 25 is elastically deformed to overcome the bulge of the tip of the elastic piece 25. The lever member 7 is elastically constrained to the case 1 because it is elastically constrained at the end of the lower long hole in the insertion hole 26.

The second insertion hole 27 is relative to the second shaft 12 of the case 1 so as to guide the lever member 7 when the lever member 7 is rotated with the lever member 7 elastically restrained to the case 1. In other words, it has an arcuate elongated hole shape centered on the first shaft 11. When an eccentric shaft 35 of a key cylinder lock 34, which will be described later, is fitted in the second insertion hole 27 instead of the second shaft 12, when the key is inserted into the key cylinder lock 34 and rotated, the key The eccentric shaft 35 provided on the rear end surface of the cylinder lock 34 rotates about the rotation center of the key, so that the lever member 7 can be moved in the lateral direction, and the lever member 7 can be moved in the lateral direction. When moved, the first shaft 11 fitted in the long hole of the first insertion hole 26 moves over the bulge of the tip due to elastic deformation of the elastic piece 25 in contact with the first shaft 11 and moves to the other end side of the long hole. Thereafter, unless the eccentric shaft 35 is forcibly returned by the rotation of the key, the first shaft 11 does not return to the original position due to the swelling of the tip of the elastic piece 25.

Therefore, when assembling the lock device having such a configuration, first, the third insertion hole 20 formed in the substrate 5a of the link member 5 is inserted into the third shaft 14 on the front side of the case 1. At this time, at the same time, one end of the torsion coil spring 6 is hooked on the connection portion between the substrate 5a and the tip portion 5b of the link member 5, and the other end is hooked on the case 1 side. If the push-on-fix 30 is fixed to the tip of the link member 5, the link member 5 is twisted on the tip 5b without being detached, and is biased counterclockwise by the spring pressure of the coil spring 6. It is pivotally supported by the case 1 side so that rotation is possible. The push-on-fix 30 is made of metal, has an insertion hole through which the third shaft 14 is inserted at the center of the ring body, and bites into the side surface of the third shaft 14 at the hole edge of the insertion hole. It has a structure in which a plurality of biting nails are raised and formed.

Therefore, this time, when the compression coil spring 4 and the lock body 3 are inserted into the storage chamber 8 of the case 1 while the guide groove on the storage chamber 8 side is aligned with the protrusion on the lock body 3 side, the lock body 3 becomes the compression coil. Since the spring 4 is biased upward by the spring pressure of the case 1 and the engaging portion 19 is exposed outward from the opening 15 of the storage chamber 5, after obtaining such a state, Using the opening that is between the cylindrical wall 10 of the case 1 and the storage chamber 8 and penetrates from the front side of the case 1 to the back side, the tip 7b of the lever member 7 having a crank shape is guided to the front side of the case 1 to lock While pushing down the body 3, the tip 7 b is brought into sliding contact with the engagement portion 19 of the lock body 3 from above, while the second insertion hole 27 formed in the substrate 7 a disposed on the back side of the case 1 is secondly inserted. The first shaft 11 is inserted into the first insertion hole while the shaft 12 is inserted. 6, the elastic piece 25 is elastically deformed and the first shaft 11 is smoothly fitted into the first insertion hole 26, so that the lever member 7 is also not detached and the case 1 It will be pivotally supported to the side. In addition, the tip end portion 5b of the link member 5 is slidably contacted with the tip end portion 7b of the lever member 7 that contacts the engaging portion 19 of the lock body 3 by the shaft support of the lock body 3 to form a three-way sliding contact portion. Will be.

Next, finally, the operating handle 2 is pressed against the front side of the case 1 while the operating claw 17 of the operating handle 2 is engaged with the connecting hole 21 of the link member 5, and the shaft portion 13 on the case 1 side and the operating handle 2 side As a result, the operating handle 2 is pivotally supported on the case 1 so that the locking device can be easily assembled as shown in FIG. Therefore, after that, if the case 1 is screwed to the central portion of the upper edge of the globe door Ba, it will be used as shown in FIG. In this case, as shown in FIGS. 7 and 13, the glove box B has a depth that allows the design surface of the operation handle 2 of the locking device and the design surface of the glove door Ba to exist on substantially the same plane. There is a recess having an insertion port 36 through which the striker 32 can pass. Since the design surface of the operation handle 2 and the design surface of the globe door Ba are arranged on substantially the same plane, the presence of the locking device itself does not become a protrusion or a depression in the vehicle.

Further, in this case, there is an operation space 31 for inserting a finger on the instrument panel P side corresponding to the operation handle 2, and the lock device itself is only fixed on the glove door Ba side. Since there is no unnecessary protruding part inside the glove box B as in the prior art, there is no need to worry about hindering access to small items, and the internal space of the glove box B can be used effectively. Become.

In actual use, when the glove box B is constrained to the lock position, the lock body 3 is moved by the spring pressure of the compression coil spring 4 in the storage chamber 8 as shown in FIG. The striker 32 is engaged between the tip portion and the receiving wall 9 to prevent the glove box B from moving in the opening direction. On the other hand, the tip portion 5b of the link member 5 is a torsion coil spring 6. Therefore, the front end portion 7b of the lever member 7 is also urged upward of the case 1 by the spring pressure of the compression coil spring 4 while being in contact with the engaging portion 19 of the lock body 3. In this state, the members 5 and 7 have no effect on unlocking. Further, in this state, the operating claw 17 of the operation handle 2 is engaged with the connecting hole 21 of the link member 5 biased counterclockwise, so that the operation handle 2 is not inadvertently rattled. Further, the lock body 3 urged by the compression coil spring 4 and the case 1 cooperate to form an enclosed space, and a striker 32 provided on the instrument panel P side via the insertion hole 36 is attached to the striker 32. The glove door Ba to which the case 1 is screwed is locked to the instrument panel P by being restrained in the space.

Conversely, when releasing the restraint at the lock position of the glove box B, a finger is inserted into the operation space 31 defined on the instrument panel P side, and the operation handle 2 is rotated from top to bottom. Then, as shown in FIG. 9, the link member 5 is rotated in the clockwise direction opposite to the urging direction by the action of the operating claw 17 engaged with the connecting hole 21 on the operation handle 2 side. And since the front-end | tip part 7b of the lever member 7 is pressed against the spring pressure of the compression coil spring 4 with the front-end | tip part 5b below the case 1, the front-end | tip part 7b of the lever member 7 is interlocked with this. The engaging part 19 of the lock body 3 is pressed, and the lock body 3 is lowered in the storage chamber 8 of the case 1. Accordingly, since the lock body 3 is disengaged from the striker 32 by this, the glove box B is allowed to move to the lock release position.

Further, when the operation handle 2 is rotated from the instrument panel P to the glove box B side, the turning force is transmitted to the lock body 3 through the three-part sliding contact portion, and the lock body 3 is lowered, so that the lock body Since an opening through which the striker 32 can pass is generated in the space surrounded by 3 and the case 1, the glove door Ba to which the case 1 is screwed can be rotated to be unlocked. In this state, when the glove door Ba is rotated in the opening direction, the glove box B is opened, and small items can be taken into and out of the glove box B.

In the open glove box B, when the glove door Ba is rotated in the closing direction, the striker 32 passes through the insertion port 36 and comes into contact with the inclined surface 3a of the lock body 3, but when further rotated, the striker 32 is locked. By pressing the inclined surface 3 a of the body 3, a component force is generated in the sliding direction of the lock body 3, and the lock body 3 is pushed down by the component force, and the space surrounded by the lock body 3 and the case 1 is generated. Opening occurs. The striker 32 enters the space through the opening, the glove door Ba rotates to close the glove box B, and the contact between the striker 32 and the lock body 3 is released. Since the lock body 3 and the case 1 form a closed space while being pushed up by the compression coil spring 4 so as to surround the striker 32, the glove door Ba is again restrained and locked to the instrument panel P side. The

Further, when operating the operation handle 2, the safety plate 18 is formed on the back surface of the operation handle 2, so that there is no risk of injury due to parts arranged on the back side of the operation handle 2, and the safety plate. Since the part can be concealed at 18, the appearance is also improved. Furthermore, in this embodiment, the operating claw 17 formed outside the rotation fulcrum of the operation handle 2 is engaged with the connection hole 21 formed outside the rotation fulcrum of the link member 5. The operation angle of the operation handle 2 becomes insensitive, the movement amount of the lock body 3 is reduced, and the distance between the operating claw 17 and the lock body 3 can be increased, so that the operation force is also reduced.

Although the torsion coil spring 6 is not shown, even if it is a compression coil spring installed between the lower surface of the front end portion 5b of the link member 5 and the case 1, the end portion of the substrate 5a of the link member 5 In this invention, the compression coil spring 4 is referred to as a first biasing member, and the torsion coil spring 6 is referred to as a second biasing member. . The locking device according to the present embodiment is not limited to the upper edge of the globe door Ba as long as it is provided at the edge of the globe door Ba, and may be provided at the side edge or lower edge of the globe door Ba. Absent. Furthermore, the lock body 3 is not only restrained with the striker 32 provided on the instrument panel P to lock the glove door Ba, but the restraint partner is a hole provided in the instrument panel P. Even if it exists, it may be a part of the instrument panel P. Further, in the locking device according to the present embodiment, the cylindrical wall 10 and the third shaft 14 of the case 1 may be arranged on either side with respect to the sliding shaft of the lock body 3, and these are described above. In the case opposite to the arrangement position, the link member 5 is always urged clockwise by the torsion coil spring 6. Therefore, it can be said that the front end portion 5b of the link member 5 is biased to the side where the lock body 3 is constantly biased.

The above embodiment is applied to a locking device that does not have a key cylinder lock, but the present invention is not limited to this, and can also be used as a locking device having a key cylinder lock. Is. In this case, the key cylinder lock 34 is a selection means for selecting a position where the link member 5 and the lever member 7 are in a sliding contact state and a position where both the links 5 and 7 are in a non-sliding contact state. As described above, the lever member 7 moves laterally to the position indicated by the solid line in FIG. 12, and thus the upper surface of the tip 7b of the lever member 7 and the link member 5 are rotated. The lower surface of the front end portion 5b is far away and is in a non-sliding contact state. In this state, when the operation handle 2 is rotated from the instrument panel P side to the glove box B side, the turning force only rotates the link member 5, and the lever member 7 cannot be rotated. Body 3 doesn't move either. Since it is in a so-called locked state and the glove box B cannot be opened, small items in the glove box B can be protected from theft and the like.

By reinserting the key into the key cylinder lock 34 and rotating it in the reverse direction, the lever member 7 moves to the position shown by the two-dot chain line in FIG. The lower surface of the tip 5a of the member 5 is in a sliding contact state. In this state, when the operation handle 2 is rotated from the instrument panel P side to the glove box B side, the turning force rotates the link member 5 and the lever member 7 as described above, and the lock body 3 is lowered. Since the locked state is released, the glove box B can be opened. Accordingly, since the link member 5 and the lever member 7 can be switched from the non-sliding contact state to the sliding contact state by the key cylinder lock 34, the key can be returned to the opened state.

Specifically, as shown in FIGS. 10 and 11, the operation handle 2 is formed with an opening 33 communicating with the cylindrical wall 10 of the case 1, while the bottom surface of the cylindrical wall 10 is removed together with the second shaft 12. If the key cylinder lock 34 is mounted in the cylindrical wall 10 through the opening 33 and the eccentric shaft 35 provided on the rear end surface of the key cylinder lock 34 is used as the second shaft 12, It can also be used as a locking device having the key cylinder lock 34. At this time, since the eccentric shaft 35 of the key cylinder lock 34 is connected between the rotation fulcrum of the lever member 7 and the operating point, it can also serve as a guide when the lever member 7 rotates, so that smooth Operation can be guaranteed.

Also in this case, the locking and unlocking of the glove box B are basically the same as those of the locking device not having the key cylinder lock 34, except for the eccentric shaft 35 of the key cylinder lock 34. When the eccentric shaft 35 is inserted into the second insertion hole 27 of the lever member 7 and the key cylinder lock 34 is locked, the eccentric shaft 35 rotates and the lever member 7 is rotated. As shown in FIG. 12, the lower end 22 of the distal end portion of the link member 5 is separated from the upper surface of the thick wall 28 of the lever member 7 as shown in FIG. Since the state is switched to the non-sliding state, even if the operating handle 2 is erroneously rotated in this state, the turning force of the link member 5 is not transmitted to the lever member 7, so that the operating hand Only two are misses, the unlocking is impossible.

In this case, the lever member 7 is arranged from the front side to the back side of the case 1 so that the cylindrical wall 10 and the key cylinder lock 34 can be arranged close to the back side of the case 1, so that the entire locking device can be arranged. It can be made thinner.

  The lock device according to the present invention eliminates an unnecessary protruding portion inside the storage body, so that there is no risk of hindering the taking in and out of small items, and the internal space of the storage body can be used effectively. Thus, the glove box which is attached to the instrument panel of the automobile so as to be openable and closable, or a locking device for locking the independent door thereof is very advantageous.
