[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] However, the locking device of Patent Document 1 does not have a structure that generates a sense of resistance to the rotation operation of the key of the user. Therefore, the user has difficulty in recognizing whether the operation has been properly performed.

[0008] In view of the above background, the present application aims to provide a locking device of a storage device in which a lock cylinder is provided to a handle, and a sense of resistance is generated to the operation of the lock cylinder.

[0009] MEANS FOR SOLVING THE PROBLEMS

[0010] To solve the above problems, one aspect of the present application is a locking device 4 of a storage device 1 having a case 2 having an opening and a lid 3 that closes the opening of the case, the locking device having: a base 15 mounted to the lid; a latch 16 supported by the base in a manner that is displaceable between a first position in which the latch engages the case to restrict displacement of the lid relative to the case and a second position in which the latch is separated from the case to enable displacement of the lid relative to the case; a handle 17 supported by the base in a manner that is rotatable, and which displaces the latch from the first position to the second position by rotation; a lock cylinder 52 provided in the handle; and a cam 60 supported by the handle in a manner that is displaceable between a third position in which the cam engages the base to restrict rotation of the handle relative to the base and a fourth position in which the cam is separated from the base to enable rotation of the handle relative to the base, the lock cylinder having a housing 53 fixed to the handle and a rotor 54 rotatably supported by the housing, the rotor and the cam engaging each other, the cam being displaced between the third position and the fourth position in accordance with rotation of the rotor, one of the handle and the cam having a concave-convex structure 48, and the other of the handle and the cam having a flexible abutting portion 62 that abuts against the concave-convex structure when the cam is positioned at a predetermined position relative to the handle to produce a feel of indexing.

[0011] According to this aspect, in the locking device of the storage device, the lock cylinder can be provided in the handle, and a feel of indexing can be produced by operation of the lock cylinder.

[0012] In the above aspect, the rotor can have a connecting piece 59 extending offset from a rotation axis of the rotor, and the cam can have a cam groove 65 that accommodates the connecting piece, the cam being displaced relative to the handle by the connecting piece pushing the cam groove.

DETAILED DESCRIPTION

[0038] Hereinafter, with reference to the drawings, an embodiment of a locking device of a glove compartment to which the present application is applied will be described in detail. In the following description, each orientation is determined based on the traveling direction of a vehicle.

[0039] Figure 1 is an exploded perspective view of the glove compartment 1. As shown in Figure 1 the glove compartment 1 as a storing device has a box 2 constituting an instrument panel, a cover 3, and a locking device 4. The box 2 is formed with an opening 5 facing forward. The cover 3 is rotatably supported to the box 2 to open and close the opening 5. The locking device 4 is maintained in a closed position of the cover 3 closing the opening 5 with respect to the box 2.

[0040] The cover 3 has a surface member 7 and a back surface member 8 which are engaged with each other. The back surface member 8 has a plate-shaped portion 8A formed in a substantially quadrangular shape and an upper side wall 8B, left and right side walls 8C, and a lower side wall (not shown) which are vertically provided toward the surface side along the periphery of the plate-shaped portion 8A, and is formed in a shallow dish shape. The locking device 4 described later is installed to the back surface member 8.

[0041] The surface member 7 is formed in a plate shape in a substantially quadrangular shape. A through hole which penetrates front and back is formed in the surface member 7. The surface member 7 is engaged with the protruding ends of the respective side walls 8B, 8C of the back surface member 8. Thus, the cover 3 forms an internal space between the surface member 7 and the back surface member 8. The support shafts 9 which protrude in the left and right directions are coaxially formed in the lower portions of the left and right side walls 8C of the back surface member 8, respectively. Each support shaft 9 is supported to a bearing hole (not shown) formed in the box 2, and thus the cover 3 is rotatably supported to the box 2.

[0042] The opening 5 of the box 2 is formed into a roughly quadrilateral shape so as to accommodate the lid 3 in the closed position. An upper wall 11A is formed at the edge 11 of the opening 5, which is opposite to the upper side wall 8B of the lid 3 in the closed position with a predetermined gap, and a transverse wall 11B is formed at the left and right side walls 8C with a predetermined gap. A limiting wall 11C is provided at a portion of the left and right transverse walls 11B that is displaced a predetermined distance from the opening end to the depth side, and protrudes toward the center of the opening 5 and extends up and down. The limiting wall 11C has a side facing the outside of the opening 5. A locking hole 12 is formed at the upper end of the left and right transverse walls 11B, which is recessed toward the left and right outsides. The locking hole 12 can be either a through hole or a bottomed hole.

[0043] The locking device 4 includes a base 15 mounted on the lid 3, a latch 16 that engages with the locking hole 12 of the box 2, and a handle 17. The base 15 is provided at the upper portion of the front side of the back member 8 within the interior space of the lid 3. The latch 16 is provided at the upper portion of the front side of the back member 8 within the interior space of the lid 3. The handle 17 is provided at the upper portion of the front side of the back member 8 within the interior space of the lid 3 and at the left end in the left-right direction.

[0044] In the following description, the up and down and front and back positions of the components are defined based on the state in which the cover 3 is in the closed position. In addition, the positions of the components when the cover 3 is in the closed position and the locking device 4 is in the locked state are defined as the initial positions.

[0045] like Figure 1 and Figure 2 As shown, the base 15 has a surface facing the front-to-back direction. The base 15 includes a first support portion 20, a handle support portion 21, and a second support portion 22. The first support portion 20 is attached to the center portion of the back member 8 in the left-right direction. The handle support portion 21 is attached to the left side of the back member 8 in the left-right direction. The second support portion 22 extends in the left-right direction between the first support portion 20 and the handle support portion 21.

[0046] The first support portion 20 supports the latch 16 and the rotating member 18. The first support portion 20 supports the latch 16 so as to be displaceable in the left-right direction.

[0047] like Figure 1 、 Figure 3 as well as Figure 4 As shown, the latch 16 has a first latch 23 and a second latch 33 extending left and right. The first latch 23 is connected to the rotating component 18 at the left end. The second latch 33 is connected to the rotating component 18 at the right end.

[0048] The latch 16 is supported so as to be slidable in the left-right direction with respect to the base 15. The latch 16 is displaceable between a first position as an initial position and a second position. In the first position, the first latch 23 is displaced to the right with respect to the base 15 as compared with the second position. The second latch 33 is displaced to the left with respect to the base 15.

[0049] In the first position, the latch 16 is engaged with the case 2. Thereby, the latch 16 restricts displacement of the cover 3 with respect to the case 2. In the second position, the latch 16 is disengaged from the case 2. Thereby, the latch 16 enables displacement of the cover 3 with respect to the case 2. The latch 16 is displaced by the handle 17 between the first position and the second position.

[0050] The first latch 23 extends in the left-right direction. The first latch 23 is supported to the first support portion 20. The first latch 23 is provided so as to be slidable in the left-right direction with respect to the first support portion 20. The first engagement portion 24 is connected to the right end portion of the first latch 23.

[0051] The first engagement portion 24 is supported to the mounting portion 25 mounted to the back member 8 of the cover 3. The first engagement portion 24 is supported so as to be slidable in the left-right direction to the mounting portion 25. The first engagement portion 24 is engaged with the lock hole 12, and is formed so as to be engageable / disengageable with respect to the case 2. The latch urging portion 26 is interposed between the first latch 23 and the mounting portion 25. The latch urging portion 26 is preferably a torsion coil spring. The first latch 23 is urged by the latch urging portion 26 so that the first engagement portion 24 approaches the lateral wall 1 IB of the cover 3.

[0052] The second latch 33 extends in the left-right direction. The second latch 33 is supported to the second support portion 22. The second latch 33 is provided so as to be slidable in the left-right direction with respect to the second support portion 22. The second engagement portion 34 is connected to the left end portion of the second latch 33. The second engagement portion 34 is engaged with the lock hole 12, and is formed so as to be engageable / disengageable with respect to the case 2.

[0053] The rotation member 18 is rotatably supported to the first support portion 20. The rotation member 18 has a rotation axis extending in the front-rear direction. The rotation member 18 has a first protruding portion 30 and a second protruding portion 31 protruding outward from the axis of the rotation axis. The first protruding portion 30 and the second protruding portion 31 are disposed in positions rotationally symmetrical about the rotation axis in the front view. The rotation member 18 is connected at the first protruding portion 30 to the left end portion of the first latch 23. The rotation member 18 is connected at the second protruding portion 31 to the right end portion of the second latch 33.

[0054] As Figure 2 , Figure 5 and Figure 6As shown, the handle support portion 21 has a first recess 37 and a second recess 38. The first recess 37 is formed in the lower portion of the handle support portion 21. The first recess 37 is recessed forward. The first recess 37 has left and right side walls 37A, an upper wall 37B connecting the upper ends of the left and right side walls 37A, and a lower wall 37C connecting the lower ends of the left and right side walls 37A. The front ends of the left and right side walls 37A, the upper wall 37B, and the lower wall 37C are connected by a bottom wall 37D. An opening 39 is formed in the upper wall 37B.

[0055] The opening 39 is formed in at least the left side portion of the upper wall 37B in the left-right direction. The opening 39 may also be formed across the upper wall 37B and bottom wall 37D of the first recess 37. The upper wall 37B is positioned at a position corresponding to the contact claw 35 in the front-back and left-right directions. The second recess 38 is formed in the lower portion of the first recess 37. The second recess 38 is recessed downward from the lower wall 37C of the first recess 37. The handle support 21 supports the handle 17.

[0056] The handle 17 is rotatably supported on the base 15. The handle 17 has a handle body 40 and a protruding piece 41 connected to the handle body 40. The handle 17 is preferably covered by a cover 42 installed at the rear thereof. The handle body 40 is formed in a box shape and is arranged in the first recess 37. A push-out portion 45 is formed at the left front portion of the handle body 40. The push-out portion 45 protrudes upward from the upper surface of the handle body 40. The push-out portion 45 is accommodated in the opening portion 39. The push-out portion 45 abuts against the abutting surface 36 of the abutting claw 35. As shown in FIG. Figure 7 As shown, a concave-convex structure 48 is formed on the right side of the left side of the handle body 40. The concave-convex structure 48 has a concave portion 49 that is concave to the left. The handle body 40 supports a cam 60 (see FIG. 1 ) described later in its interior. Figure 10 ).

[0057] like Figures 5 to 9 As shown, the extension piece 41 extends to the left from the left rear end of the handle body 40. The extension piece 41 is formed in a plate shape. The handle 17 has a rotation axis extending in the up-down direction at its rear part and on the base end side of the extension piece 41. The handle 17 rotates around the rotation axis in such a manner that the extension piece 41 moves forward and the handle body 40 moves backward. A handle force member 50 is clamped between the extension piece 41 and the base 15. The handle force member 50 is preferably a torsion coil spring. By means of the handle force member 50, the handle 17 is forced in such a manner that the main surface of the extension piece 41 faces forward and backward. A lock cylinder 52 is provided on the handle 17.

[0058] The key cylinder 52 includes a housing 53 fixed to the handle body 40 and a rotor 54 rotatably supported by the housing 53. The housing 53 is formed in a cylindrical shape extending forward and backward. The housing 53 is attached to the handle 17 at its outer peripheral surface.

[0059] The rotor 54 includes a rotor body 55. The rotor body 55 is rotatably disposed inside the housing 53. The rotor body 55 has a rotation axis extending in the front-rear direction. A keyhole 57 is formed at the rear of the lock cylinder 52.

[0060] like Figures 3-4 and Figures 8-9 As shown, the keyhole 57 is formed so that an operating key can be inserted from the rear. The keyhole 57 is preferably an elongated hole extending perpendicularly to the rotation axis of the rotor body 55. The lock cylinder 52 is formed so that the rotor body 55 rotates by rotating the operating key inserted into the keyhole 57. The keyhole 57 preferably extends in the left-right direction when the locking device 4 is locked. The keyhole 57 preferably extends in the up-down direction when the locking device 4 is unlocked. In other words, the locking device 4 is preferably locked / unlocked by rotating the operating key inserted into the keyhole 57 90 degrees. When the handle 17 is provided with a cover 42, the keyhole 57 preferably protrudes from the cover 42 to the rear.

[0061] A connecting piece 59 is provided at the front of the rotor body 55, extending offset from the rotation axis of the rotor body 55. The connecting piece 59 extends forward from the rotor body 55. A cam 60 is arranged in front of the rotor 54 at a position intersecting the rotation axis.

[0062] like Figure 10 As shown, the cam 60 includes a cam body 61 and an abutment portion 62. The cam body 61 is a plate-shaped member having surfaces facing forward and backward. A cam groove 65 is formed in the center of the cam body 61 in the vertical direction and the center in the horizontal direction.

[0063] A cam groove 65 is formed in the cam body 61. The cam groove 65 can be a through hole or a bottomed hole. The cam groove 65 can accommodate the connecting piece 59. The edge of the cam groove 65 can abut against the connecting piece 59. A locking piece 69 is connected to the lower right side of the cam body 61. The locking piece 69 has a front-to-back surface and extends downward.

[0064] The contact portion 62 is formed at the left end of the cam body 61. The contact portion 62 is formed of a flexible material. The contact portion 62 includes an arm portion 70 extending in the vertical direction (i.e., the sliding direction of the cam 60). The arm portion 70 includes a first arm portion 71 and a second arm portion 72.

[0065] like Figures 8-10 As shown, the first arm portion 71 connects the upper and lower portions of the cam body 61. The first arm portion 71 preferably has an arched shape in a front view. A protrusion 73 is formed in the vertical center of the first arm portion 71. The protrusion 73 protrudes leftward from the cam body 61. The protrusion 73 abuts against the concave-convex structure 48.

[0066] The second arm portion 72 includes an upper second arm portion 72A and a lower second arm portion 72B. The upper second arm portion 72A is located above the first arm portion 71. The lower second arm portion 72B is located below the first arm portion 71. The second arm portion 72 abuts against the handle body 40 above and below the concave-convex structure 48.

[0067] The cam 60 is supported so as to be able to slide in the vertical direction relative to the handle 17. The cam 60 is displaceable between a third position, which is an initial position, and a fourth position. In the third position, the cam 60 is displaced downward relative to the handle 17 compared to the fourth position.

[0068] like Figure 2 、 Figure 8 as well as Figure 9 As shown, in the third position, the locking piece 69 protrudes from the handle 17 toward the base 15 and is inserted into the second recess 38. As a result, the cam 60 engages with the base 15 to restrict the rotation of the handle 17. In addition, in the third position, the protrusion 73 protrudes into the second recess 38.

[0069] In the fourth position, the locking piece 69 is removed from the second recess 38. This allows the cam 60 to separate from the base 15, enabling the handle 17 to rotate relative to the base 15. Furthermore, in the fourth position, the protrusion 73 abuts against the concave-convex structure 48. The cam 60 is displaced between the third and fourth positions by the rotor 54.

[0070] As the rotor body 55 rotates, the connecting piece 59 moves within the cam groove 65. The connecting piece 59 abuts the edge of the cam groove 65, pressing the cam body 61. This causes the cam 60 to move upward or downward relative to the handle 17. The displacement of the cam 60 inserts and removes the locking piece 69 from the second recess 38. Thus, the cam 60 moves between the third and fourth positions in response to the rotation of the rotor 54.

[0071] Next, open and close Figure 1 The operation of the locking device 4 when the cover 3 is opened will be described. When the cover 3 is opened from the closed state, the operator inserts the operating key into the key hole 57 and rotates the rotor body 55 to the left. Figure 9 As shown, the connecting piece 59 moves upward within the cam groove 65. The connecting piece 59 abuts the upper edge of the cam groove 65, pushing the cam body 61 upward. This causes the cam 60 to slide upward to the fourth position, allowing the handle 17 to rotate relative to the base 15. This releases the locking mechanism 4. At this point, the protrusion 73 slides against the concave-convex structure 48 provided on the handle body 40, creating a clicky feel.

[0072] Then, if Figure 4 and Figure 6As shown, the operator pulls the right end of the handle 17 rearward. By this, the handle 17 is rotated, and the left end of the handle 17 is moved forward. By this, the push-out portion 45 is moved rightward. The push-out portion 45 then abuts against the abutting claw 35, and pushes the abutting claw 35 rightward. Further, the push-out portion 45 abuts against the edge portion of the opening portion 39. By this, the movement of the push-out portion 45 is restricted. Therefore, the rotation of the handle 17 is restricted.

[0073] The abutting claw 35 is pushed rightward, and by this, the second latch 33 is moved rightward by sliding. By this, the second protruding portion 31 connected to the right end portion of the second latch 33 is displaced rightward. By this, the rotation member 18 is rotated rightward, and the first protruding portion 30 is displaced leftward. Therefore, the first latch 23 connected to the first protruding portion 30 is moved leftward by sliding. By this, the first latch 23 and the second latch 33 are displaced from Figure 1 the case 2 shown to the second position. Therefore, the lid 3 can be opened and closed.

[0074] When the lid 3 is made to be in the open state from the closed state, as shown in Figure 3 and Figure 5 shown, the operator releases the pulling force to the handle 17. When the pulling force is released, the handle 17 is forced by the force of the handle force applying member 50 to make the main surface of the protruding piece 41 face the front and back. In addition, the first latch 23 is moved leftward by the force of the latch force applying member 26. By this, the first protruding portion 30 connected to the left end portion of the first latch 23 is displaced leftward. By this, the rotation member 18 is rotated leftward, and the second protruding portion 31 is displaced leftward. Therefore, the second latch 33 connected to the second protruding portion 31 is displaced leftward, and returns to the initial position.

[0075] The operator rotates the rotor body 55 rightward by the operation key inserted into the key hole 57. By this, as shown in Figure 8 shown, the connecting piece 59 is moved downward in the cam groove 65. The connecting piece 59 abuts against the lower portion of the edge portion of the cam groove 65, and pushes the cam body 61 downward. By this, the cam 60 is moved downward by sliding and is displaced to the third position, and the movement of the handle 17 with respect to the base 15 is restricted. That is, the lock device 4 becomes in the locked state. At this time, the protrusion 73 is in sliding contact with the concave-convex structure 48 provided to the handle body 40, and is projected into the recessed portion 49, and by this, the feeling of the degree is generated.

[0076] Next, the effects of the lock device 4 configured as described above are described. The lock device 4 of the present embodiment rotates the rotor body 55 by operating the lock cylinder 52 provided to the handle 17. By the rotation of the rotor body 55, the cam 60 is moved in the up and down directions with respect to the handle 17 between the third position and the fourth position.

[0077] Further, the handle 17 is formed with a concave-convex structure 48, and the cam 60 is formed with an abutting portion 62. The abutting portion 62 is flexible, and therefore, when the cam 60 is displaced to the third position or the fourth position with respect to the handle 17, the abutting portion 62 is flexed and abuts against the concave-convex structure 48. Therefore, in the lock device 4 of the parcel shelf 1, it is possible to provide the lock cylinder 52 in the handle 17, and to impart a sense of gradation to the operation of the lock cylinder 52. Further, by the abutting portion 62, the cam 60 is latched to the handle 17, and therefore, the movement of the cam 60 is restricted when the operation of the lock cylinder 52 is not performed.

[0078] The rotor 54 has a connecting piece 59 extending offset with respect to the rotation axis extending in the front-rear direction. The cam 60 has a cam groove 65 accommodating the connecting piece 59. When the operator operates the lock cylinder 52 to rotate the rotor body 55, the connecting piece 59 moves to push the cam groove 65, and therefore, the cam 60 moves in the up-down direction with respect to the handle 17. According to this structure, it is possible to simplify the connecting structure of the rotor 54 of the lock cylinder 52 and the cam 60.

[0079] The cam 60 has a lock piece 69 protruding from the handle 17 to the base 15 side in the third position. In the third position, the lock piece 69 is inserted into the second recess 38. Thereby, in the third position, the movement of the cam 60 in the front-rear direction with respect to the base 15 is restricted. Therefore, it is possible to simplify the latching structure of the cam 60 and the base 15.

[0080] The rotation axis of the rotor 54 extends in the front-rear direction. The cam 60 is disposed in front of the rotor 54, and is disposed at a position intersecting the rotation axis of the rotor 54. Further, the cam 60 is slidably supported to the handle 17 in the up-down direction. Thereby, it is possible to efficiently dispose the cam 60 in the handle 17.

[0081] The handle 17 has a rotation axis extending in the up-down direction. The cam 60 is slidably supported to the handle body 40 in the up-down direction. Therefore, the cam 60 is slidably supported to the handle 17 in a direction parallel to the rotation axis of the handle 17. Thereby, it is possible to efficiently dispose the cam 60 in the handle 17.

[0082] The abutting portion 62 has a flexible first arm portion 71 and a second arm portion 72 extending in the up-down direction. A protrusion 73 is provided to the first arm portion 71. The protrusion 73 abuts against the concave-convex structure 48 of the handle 17. Thereby, it is possible to impart a sense of gradation to the operation of the lock cylinder 52.

[0083] The concave-convex structure 48 has a recess 49 recessed in the left-right direction (i.e., a direction orthogonal to the sliding direction of the cam 60). The protrusion 73 can protrude into the recess 49. Thereby, when the protrusion 73 protrudes into the recess 49, it is possible to impart a sense of gradation to the operation of the lock cylinder 52.

[0084] The above completes the description of the specific embodiments, but the present application is not limited to the above-described embodiments and can be implemented in a wide variety of ways. For example, in the above-described embodiments, an example in which the locking device of the present application is applied to the glove box 1 is described, but the locking device of the present application can be applied to various storage devices that close an opening by a lid that can be turned, such as furniture, a storage box, and the like, such as an overall kitchen.
