This application is entitled to and claims the benefit of Japanese Patent Application No. 2023-017789 filed on Feb. 8, 2023, the disclosure of which including the specification, drawings and abstract is incorporated herein by reference in its entirety.
The present invention relates to a lock apparatus that can lock a second member to a first member and also release the lock, and a storage apparatus equipped with the same.
Conventionally, in an opening/closing apparatus such as a glove box mounted on a vehicle such as an automobile, a lock apparatus is used that locks a lid body, which is a second member, to a main body portion, which is a first member, so as to be openable and closable. In such a lock apparatus, tip portions of a pair of long rods, which are lock bodies, are inserted into a lock receiving portion in an urged state to lock the lid body, and a user such as an occupant slides or rotates an operating handle, so that in response to the operation of the operating handle, the rod resists urging and retreats from a lock receiving portion in a longitudinal direction, thereby releasing the lock.
A rotor, which is a rotatable rotation body, is used to interlock the pair of rods with the operation of the operating handle. The other end portions of the rods are rotatably connected to positions opposite to each other with respect to a rotation center of the rotor, and when the rotor rotates in response to an external force generated by the operation of the operating handle, the pair of rods move in opposite directions, so that one end portion of each of these rods is configured to be retreated from the lock receiving portion. A spherical protrusion portion provided on one side is inserted into an insertion portion recessed on the other side, and held by an elastic claw that is a retaining portion protruding from an inner wall portion of the insertion portion, so that the rotor and the other end portion of the rod are connected (For example, see Patent Literatures 1 to 3.)
However, in the case of the above configuration, the inner wall portions of the insertion portion that regulate the position of the protrusion portion are set in a planar shape, with one pair facing each other in the longitudinal direction of the rod and one pair facing each other in the width direction of the rod. As a result, it is difficult to maintain a large contact area between the outer peripheral surface of the spherical protrusion portion and the inner wall portion, and further measures are required to prevent rattling between the protrusion portion and the insertion portion.
The present invention was made in view of these points, and an object of the present invention is to provide a lock apparatus suppressing rattling at a connecting portion that connects a rotation body and a lock body, and a storage apparatus equipped with the same.

In
Lock apparatus 1 includes base body 10 illustrated in
In addition, hereinafter, front-rear directions are defined based on a direction seen from a user's side, and arrow FR direction in the drawing, which is the user's side, is a front or near side, and the opposite direction, which is arrow RR direction, is a rear or behind side. In the illustrated example, lock body 12 is disposed to extend in left-right directions (arrows L and R directions), and directions perpendicular to these front-rear and left-right directions (arrows U and D directions) are explained as up-down directions, but are not limited to these, and the left-right directions and the up-down directions may be changed as appropriate depending on an installation posture of lock apparatus 1.
Rotation body 11 is also called a rotor, and is an interlocking member that is interlocked by rotation to move or slide lock bodies 12 in opposite directions. Rotation body 11 is rotatably supported by support shaft 15 formed on base body 10 in the opposite direction. Therefore, rotation body 11 is rotatably supported by any one of the first member and the second member via base body 10. In the present embodiment, support shaft 15 protrudes, for example, at a rear portion of base body 10, that is, at a position opposite to operated body 13, and allows rotation body 11 to rotate left and right.
Rotation body 11 has supported portion 17 supported by support shaft 15 and a pair of arm portions 18 extending from supported portion 17 in a radial direction.
In the illustrated example, supported portion 17 is formed in a cylindrical shape, and support shaft 15 is inserted from the front side to the rear side. The pair of arm portions 18 extend on opposite sides, respectively with respect to the center of supported portion 17, that is, the rotation center of rotation body 11. In other words, the pair of arm portions 18 are located on one side and the other side with respect to the rotation center of rotation body 11. Lock body 12 is connected to each of arm portions 18. In the present embodiment, arm portions 18 are located above and below supported portion 17.
Preferably, rotation body 11 is urged in a rotational direction by urging means 20. Urging means 20 is, for example, a coil spring, a torsion spring, or the like, and is held on support shaft 15 on the front side of rotation body 11, that is, between rotation body 11 and base body 10, and has one end fixed to base body 10, and the other end fixed to rotation body 11. An urging direction of rotation body 11 by urging means 20 is a direction in which lock apparatus 1 holds the lock. In the present embodiment, rotation body 11 is provided with stopper portion 22 for regulating a rotation range of rotation body 11 against the urging by urging means 20. In the illustrated example, stopper portion 22 protrudes at the front portion of rotation body 11 and is configured to regulate the rotation range of rotation body 11 by abutting against stopper receiving portion 23 formed on base body 10.
Lock body 12 is an elongated member also called a rod, a pin, or the like. Lock body 12 is movable in a first direction, and is a slide member that locks the second member such that one end portion side (tip portion side) is inserted into and removed from a pair of lock receiving portions such as a hole portion provided in the other of the first member and the second member by respective movement. In the present embodiment, lock body 12 is movable in its longitudinal direction. That is, in the present embodiment, the first direction is the longitudinal direction of lock body 12, and is the left-right direction in the illustrated example.
In the present embodiment, a pair of lock bodies 12 are formed on the left and right sides of base body 10 and extend in the left-right directions with respect to base body 10. One lock body 12a located on the right side with respect to base body 10 has one end portion side, which is the right end side, extending from base body 10 to the right side, and other lock body 12b located on the left side with respect to base body 10 has one end portion side, which is the left end side, extending from base body 10 to the left side. Lengths of lock bodies 12a and 12b are set according to the disposition of lock apparatus 1 in storage apparatus 2 (
Further, in the present embodiment, at least one of lock bodies 12 is guided by base body 10 in the moving direction. In the illustrated example, one lock body 12a is held by guide portion 28 formed at the rear portion of base body 10 so as to be slidable in the left-right directions.
Further, each other end portion (base end portion) of lock body 12 is rotatably connected to arm portion 18 of rotation body 11 via connecting portion 30. In the present embodiment, the right end side of one lock body 12a is connected to one arm portion 18a on the upper side with respect to the rotation center of rotation body 11, and the right end side of other lock body 12b is connected to other arm portion 18b on the lower side with respect to the rotation center of rotation body 11.
Connecting portions 30 may each have the same configuration, but in the present embodiment, they have mutually different configurations. One connecting portion 30a that connects one lock body 12a and one arm portion 18a of rotation body 11 includes protrusion portion 32a formed on one of one lock body 12a and one arm portion 18a of rotation body 11, and insertion portion 33a formed on the other of one lock body 12a and one arm portion 18a of rotation body 11. In the present embodiment, protrusion portion 32a protrudes forward from a position near the tip portion of one arm portion 18a of rotation body 11, and insertion portion 33a is formed at the rear portion of one lock body 12a.
Protrusion portion 32a illustrated in
Moreover, insertion portion 33a illustrated in
Moreover, in the present embodiment, insertion portion 33a is a hole portion formed by penetrating one lock body 12a in the front-rear direction, which is a thickness direction. Further, the lower part of insertion portion 33a is open. That is, the lower part of insertion portion 33a directly communicates with the outside of one lock body 12a.
Further, as illustrated in
Protrusion portion 32b illustrated in
Insertion portion 33b illustrated in
Holding wall portion 43 is formed into a cylindrical shape. Holding wall portion 43 has a cylindrical shape with a diameter dimension that is equal or approximately equal to the outer peripheral surface of general portion 36b of protrusion portion 32b. Therefore, holding wall portion 43 contacts or interferes with the outer peripheral surface of general portion 36b of protrusion portion 32b inserted into insertion portion 33b without having a gap.
Holding wall portions 43 are set in pairs in a direction inclined with respect to the left-right direction which is the longitudinal direction of lock body 12, and the up-down direction which is the width direction of lock body 12, when viewed from the insertion direction of protrusion portion 32b into insertion portion 33b, that is, from the rear to the front. Further, in the present embodiment, holding wall portions 43 are set in pairs in a plurality of directions that are inclined with respect to the left-right direction and the up-down direction when viewed from the rear to the front, and are symmetrical to each other in the left-right direction. In short, with respect to the central axis of protrusion portion 32b inserted into insertion portion 33b, holding wall portions 43 are set at diagonally upper and diagonally lower parts on both left and right sides, respectively, and holding wall portions 43a and 43a, and holding wall portions 43b and 43b, which face each other in a diagonal direction with respect to the central axis of protrusion portion 32b, form pairs, respectively.
Holding wall portion 43 is formed with retaining portion 46 that holds protrusion portion 32b from coming off from insertion portion 33b. Retaining portion 46 is a claw portion that is engaged with constricted portion 37 of protrusion portion 32b inserted into insertion portion 33b. Retaining portion 46 is set on the insertion side of protrusion portion 32b of each of holding wall portions 43, that is, an inner edge of the rear end portion in the present embodiment. Therefore, like holding wall portions 43, retaining portions 46 are set in pairs in a direction inclined with respect to the left-right direction which is the longitudinal direction of lock body 12, and the up-down direction which is the width direction of lock body 12, when viewed from the insertion direction of protrusion portion 32b into insertion portion 33b, that is, from the rear to the front. Further, in the present embodiment, retaining portions 46 are set in pairs in a plurality of directions that are inclined with respect to the left-right direction and the up-down direction when viewed from the rear to the front, and are symmetrical to each other in the left-right direction. In short, with respect to the central axis of protrusion portion 32b inserted into insertion portion 33b, retaining portions 46 are set at diagonally upper and diagonally lower parts on both left and right sides, respectively, and retaining portions 46 and 46, which are formed on holding wall portions 43a and 43a, and retaining portions 46 and 46, which are formed on holding wall portions 43b and 43b facing each other in a diagonal direction with respect to the central axis of protrusion portion 32b, form pairs, respectively.
Furthermore, gap portion 47 is formed between holding wall portions 43. Gap portion 47 reduces an insertion load by bending holding wall portion 43 when protrusion portion 32b is inserted into insertion portion 33b. Gap portion 47 is continuous with insertion portion 33b and is formed between holding wall portions 43a and 43b. In the present embodiment, gap portion 47 includes slit 47a formed between holding wall portions 43a and 43b that are adjacent to each other in the left-right direction that is the longitudinal direction of lock body 12, and notch portion 47b formed between holding wall portions 43a and 43b that are adjacent to each other in the up-down direction that is the width direction of lock body 12. Therefore, gap portion 47 allows each holding wall portion 43 to be elastically deformed in a direction away from the center portion of insertion portion 33b or the central axis of protrusion portion 32b inserted into lock body 12.
Slit 47a is formed to extend linearly in the up-down direction. Slit 47a is located on the insertion side of protrusion portion 32b, that is, at the rear portion thereof in insertion portion 33b. In the illustrated example, slit 47a is formed in the shape of groove at the rear portion of insertion portion 33b. Slit 47a is continuous from insertion portion 33b over the upper and lower parts of insertion portion 33b, and the upper end portion of slit 47a located at the end portion opposite to insertion portion 33b, that is, at the upper part of insertion portion 33b, and the lower end portion of slit 47a located at the lower part of insertion portion 33b communicate with the outside of lock body 12 and are open, respectively.
Notch portion 47b is formed to extend in the left-right direction. Like insertion portion 33b, notch portion 47b is formed by penetrating lock body 12b in the front-rear direction which is the thickness direction being continuous with insertion portion 33b. In the illustrated example, notch portion 47b is formed so that the width thereof gradually becomes narrower toward the tip portion side than the base end portion side which is insertion portion 33b side, that is, is tapered. Further, notch portion 47b gradually widens from the rear portion toward the front portion with respect to insertion portion 33b.
Further, operated body 13 illustrated in
Further, pressurizing portion 51 protrudes on the rear portion of operated body 13, that is, on the side facing base body 10, and pressurizing portion 51 is inserted from the front side to the rear side into hole portion 52 formed by penetrating base body 10 in the front-rear direction, and faces pressure receiving portion 53 of one lock body 12a held by guide portion 28 at the position of the rear portion of base body 10, as illustrated in
When assembling lock apparatus 1, first, rotation body 11, and lock bodies 12a and 12b are connected by connecting portion 30. That is, protrusion portion 32a formed on rotation body 11 is inserted between abutting wall portions 40 and 41 of insertion portion 33a formed on one lock body 12a, and protrusion portion 32b formed on rotation body 11 is inserted into insertion portion 33b formed on other lock body 12b.
At this time, when protrusion portion 32b is aligned with insertion portion 33b and pushed in, inclined portion 35b of protrusion portion 32b is first inserted between holding wall portions 43a and 43a and between the holding wall portions 43b and 43b of insertion portion 33b. Further, when protrusion portion 32b is pushed into insertion portion 33b, and general portion 36b of protrusion portion 32b abuts between retaining portions 46 and 46 formed on holding wall portions 43a and 43a, and between retaining portions 46 and 46 formed on holding wall portions 43b and 43b, holding wall portions 43a and 43a, and holding wall portions 43b and 43b are elastically pushed to be open by gap portion 47, and general portion 36b of protrusion portion 32b enters the inner part of insertion portion 33b while climbing over retaining portions 46 and 46. Then, when general portion 36b of protrusion portion 32b passes through retaining portions 46 and 46, and constricted portion 37 reaches the position of retaining portion 46, holding wall portions 43a and 43a, and holding wall portions 43b and 43b are deformed back, retaining portion 46 is caught on constricted portion 37, and protrusion portion 32b is engaged with and held in insertion portion 33b a state of being prevented from coming off.
After that, supported portion 17 of rotation body 11 is press-fitted into support shaft 15 of base body 10, and rotation body 11 together with urging means 20, urging means 20 and lock bodies 12a and 12b are assembled to the rear portion of base body 10, operated body 13 is rotatably assembled from the front portion of base body 10 to shaft support portion 50 of base body 10 while inserting pressurizing portion 51 into hole portion 52, pressurizing portion 51 faces pressure receiving portion 53 of one lock body 12a, and thereby lock apparatus 1 is assembled. Assembled lock apparatus 1 is attached to storage apparatus 2 by attaching base body 10 and other lock body 12b to the first member or the second member, for example, the inner member of lid member 5 illustrated in
In lock apparatus 1, when lid member 5 is in the position where opening portion 3 is closed, rotation body 11 is urged by urging means 20, so that abutting wall portion 41 of insertion portion 33a abuts against protrusion portion 32a, and thereby one lock body 12a is pressed to the right side, protrusion portion 32b inserted into insertion portion 33b is pushed to the left side, thereby pressing other lock body 12b to the left side, and lock portions 26 and 26 of lock bodies 12a and 12b are held in a state of being inserted into the lock receiving portions, respectively, and lid member 5 is locked to main body portion 4.
Further, when releasing the lock by lock apparatus 1, if the user rotates operated body 13, pressurizing portion 51 of operated body 13 abuts against pressure receiving portion 53 of one lock body 12a, one lock body 12a is pressed to the left side via pressure receiving portion 53, and thereby one lock body 12a moves to the left side along guide portion 28 and abutting wall portion 40 of insertion portion 33a abuts against protrusion portion 32a, so that one arm portion 18a of rotation body 11 is pushed to the left side against the urging of urging means 20. Therefore, rotation body 11 rotates around support shaft 15, and other lock body 12b, which is connected to other arm portion 18b of rotation body 11 opposite to one lock body 12a via other connecting portion 30b, is pulled to the right side and moves to the right side as rotation body 11 rotates. That is, the pair of lock bodies 12 move in opposite directions each other via rotation body 11, lock portion 26 is pulled out from the lock receiving portion, and the lock by lock apparatus 1 is released.
As described above, according to the first embodiment, in insertion portion 33b that rotatably receives protrusion portion 32b of connecting portion 30, by setting holding wall portion 43 having the cylindrical shape and retaining portion 46 protruding from holding wall portion 43 of insertion portion 33b holding the outer peripheral surface of protrusion portion 32b, which form pairs in a direction inclined with respect to the left-right direction which is the longitudinal direction and moving direction of lock body 12, and the up-down direction which is the width direction orthogonal thereto, when viewed from the insertion direction of protrusion portion 32b into insertion portion 33b, protrusion portion 32b is held by retaining portion 46 while being sandwiched between holding wall portions 43 with a large surface area without any clearance, and rattling at connecting portion 30 can be suppressed.
Further, by setting holding wall portion 43 and retaining portions 46 in pairs in a plurality of directions that are inclined with respect to the left-right direction and the up-down direction when viewed from the insertion direction of protrusion portion 32b into insertion portion 33b, and are directions symmetrical to each other in the left-right direction, protrusion portion 32b can be held by retaining portion 46 while being sandwiched between holding wall portions 43 of insertion portion 33b in a well-balanced manner with a large surface area without any clearance, so that rattling at connecting portion 30 can be suppressed more reliably.
Furthermore, since gap portions 47, which are located between holding wall portions 43 continuous to insertion portion 33b, are formed in the left-right direction and the up-down direction, respectively, holding wall portion 43 can be easily bent along the shape of protrusion portion 32b when protrusion portion 32b is inserted into insertion portion 33b, and the load during the insertion can be suppressed.
Furthermore, in a case where the protrusion portion is spherical, when the protrusion portion is inserted into the insertion portion, the load continues to increase until the maximum diameter position of the protrusion portion passes between retaining portions 46 and 46, whereas by making protrusion portion 32b a spindle-shape, when protrusion portion 32b is inserted into insertion portion 33b, if inclined portion 35b passes between retaining portions 46 and 46, since general portion 36b having a constant or substantially constant diameter dimension passes between retaining portions 46 and 46, the load does not increase. Therefore, the load when inserting protrusion portion 32b into insertion portion 33b can be suppressed.
Therefore, since protrusion portion 32b can be easily attached to insertion portion 33b and held without rattling without setting a strong hook, or the like, the workability of connection by connecting portion 30 is improved, and since there is no need to apply an unreasonable load when inserting protrusion portion 32b into insertion portion 33b, in a case where protrusion portion 32b and insertion portion 33b are made of synthetic resin, it is possible to suppress whitening, scraping, or the like of protrusion portion 32b and insertion portion 33b.
Further, in the present embodiment, since the structure is such that one lock body 12a is moved by applying an external force directly to one lock body 12a by the operation of operated body 13, and rotation body 11 is directly pushed and rotated by one lock body 12a, even if there is some clearance between protrusion portion 32a and insertion portion 33a in one connecting portion 30a between one lock body 12a and rotation body 11, no rattling occurs during rotation of rotation body 11.
By including lock apparatus 1 described above, it is possible to provide storage apparatus 2 having a high-class feel, in which rattling during operation of operated body 13 due to rattling in connecting portion 30 is suppressed.
Note that in the first embodiment, protrusion portion 32b is formed on rotation body 11, and insertion portion 33b and gap portion 47 are formed on lock body 12, but the present invention is not limited to this, and as in the second embodiment illustrated in
The present invention is suitably used for the lock apparatus which locks the lid member of the storage apparatus for vehicles, for example.
