Description

[Technical field]

[0001] The present invention relates to a locking device, and more particularly to a locking device for a luggage storage facility that stores and keeps luggage delivered by a delivery person such as a parcel company. [Background technology]

[0002] Conventionally, there are an increasing number of cases where delivery boxes are installed in detached houses to receive parcels delivered by delivery persons such as delivery companies. As such a delivery box, a storage box equipped with a door, an electric lock for the door, a control circuit for controlling the locking and unlocking of the electric lock, and a power source for supplying electric power is known as a conventional technology (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-056775 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the storage box of the above-mentioned conventional technology, the locking and unlocking of the electric lock is controlled using power from a power source. Therefore, for example, when power is not supplied to the electric lock due to a power shortage in the power source, or when the electric lock malfunctions due to the infiltration of rainwater or impact when opening and closing the door, there is a problem that the electric lock cannot be locked or unlocked. In addition, since the operation for locking and unlocking the electric lock is complicated, there is also a problem that delivery persons such as delivery companies who are unfamiliar with the operation have difficulty in locking the electric lock.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and its objective is to provide a locking device that is easy to operate and durable as a locking device for a luggage storage facility that stores and keeps luggage delivered by a delivery person such as a courier company. [Means for solving the problem]

[0006] In view of the above problems, one aspect of the present invention has the following configuration. A locking device for a luggage storage bin is provided on a door of the luggage storage bin, the locking device comprising: a housing that can be attached to the door; and a cylinder lock that is attached to the housing and unlocked by a predetermined key. The cylinder lock comprises an operation knob that has a key insertion hole through which a key is inserted and that can be manually rotated between a first position and a second position; an inner cylinder that is provided rotatably integrally with the operation knob; an outer cylinder that houses and holds the inner cylinder so that the inner cylinder can be rotated relatively to the outer cylinder; a rotation restriction portion that restricts the relative rotation of the inner cylinder with respect to the outer cylinder; and a locking mechanism that can be rotated integrally with the inner cylinder. and a locking member that is provided on the outer cylinder and is unlocked when the operating knob is located at the first position and locked when the operating knob is located at the second position, wherein the rotation control unit allows rotation of the inner cylinder relative to the outer cylinder without using the specified key when the operating knob is rotated from the first position to the second position, and controls rotation of the inner cylinder relative to the outer cylinder when the operating knob is rotated from the second position to the first position. Effect of the Invention

[0007] With the above-described configuration, the locking device for luggage storage of the present invention can be locked simply by turning the operating knob without using a specific key, and the locking structure is simple and not complicated, making it easy to operate and durable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] An example of a locking device for a luggage storage according to an embodiment of the present invention will now be described. (Overall structure) First, the overall structure of the luggage storage bin 100 and the locking device 1 will be described. Fig. 1(a) is a schematic perspective view showing the exterior of a luggage storage bin to which a locking device according to an embodiment of the present invention is attached, and Fig. 1(b) is a perspective view showing the exterior of the locking device. Fig. 2 is a front view of the locking device, Fig. 3 is a side view of the locking device, and Fig. 4 is a rear view of the locking device.

[0010] The luggage storage 100 (for example, a delivery box) is configured to include a box-shaped storage body 110 that is open on the front and has a storage space inside for storing luggage such as delivery items, and a door 120 that opens and closes the opening of the storage body 110. A lock device 1 is attached to the door 120 of the luggage storage 100 configured in this manner. This luggage storage 100 is installed, for example, near the entrance of a building such as a house, and is configured to store and keep (hand over) luggage delivered by a delivery person such as a delivery company.

[0011] The door 120 of the luggage storage 100 is pivotally supported on one side facing the opening of the storage body 110 so as to be freely rotatable about a vertical axis, and is configured to open and close the opening of the storage body 110. In this embodiment, the locking device 1 is attached to the open end side of the door 120 (the left side of the door 120 in the illustrated example). As shown in FIG. 1(b), this locking device 1 includes a housing 2 and a cylinder lock 3, and is used to lock or unlock the door 120 of the luggage storage 100.

[0012] In the following description, a state in which the door 120 of the luggage storage bin 100 is closed will be referred to as a "closed state," and a state in which the door 120 of the luggage storage bin 100 is open will be referred to as an "open state." In addition, when the door 120 of the luggage storage 100 is closed in the "closed state," a state in which the locking member 8 (see Figures 3 and 4) described later is engaged with the receiving member 110a (see Figure 11(a)) provided on the storage main body 110 (locked state) is referred to as the "locked state," and when the door 120 of the luggage storage 100 is closed in the "closed state," a state in which the locking member 8 is disengaged from the receiving member 110a (see Figure 9(a)) (unlocked state) is referred to as the "unlocked state." In addition, the operation of changing the door 120 from an "open state" to a "closed state" to a "locked state" is referred to as a "locking operation," and the operation of changing the door 120 from a "closed state" and a "locked state" to an "open state" through an "unlocked state" is referred to as an "unlocking operation."

[0013] Next, each structure of the lock device 1 according to the embodiment of the present invention will be specifically described with reference to the drawings. <Case>

[0014] 2 to 4, the housing 2 has a front wall member 21, a pair of side wall members 22, an upper wall member 23, a lower wall member 24, and a rear wall member 25, and is formed in a generally box-like shape. The housing 2 can be formed, for example, from a synthetic resin material. In this case, for example, the housing 2 can be constructed by integrally molding any of the wall members 21 to 25, and joining the remaining wall members with fixing means such as screws.

[0015] 2, a handle 26 is provided on the front wall member 21 of the housing 2. The handle 26 is formed as a recess recessed rearward on one left-right end side of the front wall member 21, and functions as a gripping portion when opening and closing the door 120. Note that the shape, structure, and arrangement of the handle 26 are not limited to this example, and may be configured to be gripped when opening and closing the door 120 of the luggage storage 100.

[0016] Further, a through hole 21a penetrating in the front-rear direction is provided in the front wall member 21 of the housing 2, and an operating knob 4 of a cylinder lock 3 (see FIG. 5), which will be described later, is inserted and positioned in this through hole 21a.

[0017] 2, a first display section 27 that displays the operation content of the operation knob 4 is provided on the front wall member 21 of the housing 2 so as to surround the through-hole 21a. On this first display section 27, for example, the word "OPEN" 27a indicating that the current position of the operation knob 4 is in the "unlocked state", an operation mark 27b (arrow) indicating the operation direction for changing the operation knob 4 from the "unlocked state" to the "locked state", and a position mark 27c (circle) indicating each operation position of the operation knob 4 are displayed by printing, engraving, or the like.

[0018] A deliverer (e.g., a home delivery company) can visually confirm the state (rotation position and operation content) of the operation knob 4 from this first display section 27. Specifically, as shown in Fig. 2, when the position mark 45 (triangle mark) displayed on the operation knob 4 is aligned with the position mark 27c corresponding to the word "OPEN" displayed on the first display section 27 of the front wall member 21, the deliverer can know that the door 120 of the luggage storage unit 100 is in the "unlocked state."

[0019] Furthermore, from this state, by rotating the operating knob 4 in the operating direction (direction of the arrow) indicated by the operating mark 27b to the position of the position mark 27c, which is 90 degrees shifted, it can be understood that the door 120 of the luggage storage shed 100 will be in the "locked state." Note that, for example, a character such as "CLOSE" may be additionally displayed near the position mark 27c shifted by 90 degrees.

[0020] 3 and 4, a latch mechanism 28 is provided at the rear of the housing 2 to hold the door 120 in a closed state at the opening of the storage main body 110. The latch mechanism 28 includes a latch holding portion 28a, a latch member 28b, and a latch biasing spring (not shown) that biases the latch member 28b. The latch member 28b is supported by the latch holding portion 28a attached to the rear of the housing 2 in a state in which it can move in the left-right direction, and the latch biasing spring (not shown) biases the tip of the latch member 28b so that it protrudes laterally.

[0021] Furthermore, at the tip of latch member 28b, an inclined surface (not shown) that slides from the rear and an inclined surface (not shown) that slides from the front are formed against a frame portion provided at the opening of luggage storage 100. As a result, when handle 26 is pushed or pulled to open or close door 120, the inclined surfaces of latch member 28b slide against the frame portion of luggage storage 100, and latch member 28b is configured to be drawn into door 120 against the biasing force of the latch biasing spring.

[0022] The storage cabinet main body 110 is provided with a receiving member 110a (see FIG. 11(a)) that engages (locks) with a locking member 8 (see FIGS. 3 and 4) described later. When the locking member 8 engages (locks) with the receiving member 110a, the door 120 is put into a locked state.

[0023] <Cylinder lock> Next, each component of the cylinder lock 3 will be described. Fig. 5(a) is a perspective view showing the appearance of the cylinder lock constituting the locking device according to the embodiment of the present invention, and Fig. 5(b) is a side view of the cylinder lock. Fig. 6 is a perspective view showing the cylinder lock disassembled. Fig. 7(a) is a rear view of the operation knob, and Fig. 7(b) is a perspective view of the operation knob attached to the inner cylinder, seen obliquely from behind. Fig. 8(a) is a perspective view of the outer cylinder, seen obliquely from below, and Fig. 8(b) is a front view of the outer cylinder. As shown in FIGS. 5 and 6, the cylinder lock 3 includes an operating knob 4, an inner cylinder 5, a tumbler 6, an outer cylinder 7, and a locking member 8 (locking cam).

[0024] [Control knob] The operation knob 4 is configured as an operation knob that can be manually turned by the fingers, and as shown in Fig. 6, for example, is formed in a substantially cylindrical shape (cap-like) with a bottom, having a substantially disk-shaped front wall 41 and a substantially cylindrical peripheral wall 42 extending rearward from the periphery of the front wall 41. As shown in Fig. 2, this operation knob 4 is inserted into a through-hole 21a formed in the front wall member 21 of the housing 2, and for example, a delivery person such as a delivery company can turn this operation knob 4 to lock the luggage storage unit 100.

[0025] 7(a), a fitting protrusion 43 is formed on the front inner peripheral surface of the peripheral wall 42 of the operation knob 4, which fits (engages) with a fitting groove 52 (see FIGS. 6 and 7(b)) formed in the front end of the inner cylinder 5 to fix the position, and the operation knob 4 can be detachably attached to the inner cylinder 5. Furthermore, by fitting (engaging) the fitting protrusion 43 of the operation knob 4 with the fitting groove 52 of the inner cylinder 5, they rotate together.

[0026] In addition, a key insertion hole 44 is formed through the operation knob 4 to guide the key A (see FIG. 1(b)) into the keyhole 51 of the inner cylinder 5. A user who owns the key A (e.g., a homeowner) can "unlock" the lock device 1 by inserting the key A into the key insertion hole 44.

[0027] 2 and 5, position marks 45 (triangular marks) indicating the operating position of the operation knob 4 are provided on the front wall 41 of the operation knob 4 adjacent to positions above and below the key insertion hole 44. The position marks 45 can be displayed by, for example, printing or engraving.

[0028] [Inner cylinder] 6, the inner cylinder 5 has a keyhole 51 extending in its axial direction, and is formed with a plurality of tumbler mounting holes 53 penetrating the inner cylinder 5 in the radial direction. A tumbler 6 and a spring 63 for biasing the tumbler 6 are disposed inside each tumbler mounting hole 53. The spring 63 biases the tumbler 6 so as to push it out of the tumbler mounting hole 53 through the opening of the tumbler mounting hole 53.

[0029] Additionally, a plurality of fitting grooves 52 extending in the axial direction of the inner cylinder 5 are formed on the outer peripheral surface of the front end portion of the inner cylinder 5. The fitting grooves 52 are fitted (engaged) with fitting protrusions 43 (see FIG. 7(a)) formed on the front inner peripheral surface of the peripheral wall 42 of the operation knob 4, whereby the inner cylinder 5 rotates integrally with the operation knob 4.

[0030] Further, at the rear end of the inner cylinder 5, a shaft portion 54 for mounting and fixing a locking member 8 (locking cam) described later is provided so as to extend rearward with the axis of the inner cylinder 5 as its center.

[0031] 6, the opening of the keyhole 51 formed in the inner cylinder 5 is covered by a movable shutter 55 that prevents the infiltration of rainwater, etc. This shutter 55 is provided so as to be able to slide to open and close the keyhole 51, and is biased by an elastic body 55a (e.g., a coil spring) to close the keyhole 51. Note that this shutter 55 is configured so as to slide at the tip of the key A when the key A is inserted into the key insertion hole 44, thereby opening the keyhole 51.

[0032] A cap 56 is detachably provided at the front end of the inner tube 5. The cap 56 is, for example, made of synthetic resin and formed in a generally circular flat plate shape when viewed from the front, and has a through hole 56a for inserting the key A. The cap 56 functions as a protective member that covers the front end surface of the inner tube 5, and also as a support member that supports the shutter 55 and the elastic body 55a provided at the front end of the inner tube 5.

[0033] [Regulation member (tumbler)] The tumbler 6 serving as the regulating member is, for example, a flat metal plate-like member as shown in Fig. 6. The tumbler 6 is configured to be attached to a tumbler attachment hole 53 formed in the inner cylinder 5, and to be inserted and received in each of the recesses 71 to 74 (see Fig. 8) formed on the inner circumferential surface of the outer cylinder 7 described later by the biasing force (elastic force) of a spring 63.

[0034] The tumbler 6 as a regulating member functions as a rotation regulating portion together with the first receiving recess (first recess 71, third recess 73) and the second receiving recess (second recess 72, fourth recess 74) formed on the inner surface of the outer tube 7.

[0035] In this embodiment, the multiple tumblers 6 include a first tumbler group 61 that is biased to protrude toward one radial direction of the inner cylinder 5 relative to the multiple tumbler mounting holes 53 formed in the inner cylinder 5, and a second tumbler group 62 that is biased to protrude toward the other radial direction of the inner cylinder 5 relative to each tumbler mounting hole 53. The tumblers 6 that constitute the first tumbler group 61 and the tumblers 6 that constitute the second tumbler group 62 are similarly configured and have symmetrical structures.

[0036] Each tumbler 6 has a substantially rectangular key insertion hole 6a into which the key A is inserted, and a protrusion 6b protruding from one side of the tumbler 6. This protrusion 6b is engaged with a spring 63 (e.g., a coil spring), and when the key A is not inserted in the key insertion hole 6a, the protrusion 6b is biased outwardly of the tumbler attachment hole 53 by the spring 63, so that a part (end) of the tumbler 6 protrudes outward from the outer circumferential surface of the inner cylinder 5.

[0037] In this embodiment, the tumblers 6 are configured to include the first tumbler group 61 and the second tumbler group 62, but the present invention is not limited to this example and may be configured to include only one of the tumbler groups. Also, the number of tumblers 6 constituting each tumbler group can be set arbitrarily.

[0038] [Outer cylinder] The outer cylinder 7 is formed in a substantially cylindrical shape, as shown in Fig. 6. The outer cylinder 7 rotatably supports the inner cylinder 5 on its inner circumferential surface, and is attached and fixed to the housing 2 via an attachment member (not shown) such as a mounting bracket. 8(a) and 8(b), a first recess 71, a second recess 72, a third recess 73, and a fourth recess 74 are formed on the inner peripheral surface of the outer cylinder 7 at positions spaced apart by 90 degrees in the circumferential direction. In addition, between the second recess 72 and the third recess 73, and between the fourth recess 74 and the first recess 71, inner cylinder support surfaces 75 and 76 that support the outer peripheral surface of the inner cylinder 5 are formed.

[0039] 8(b), the first recess 71 and the third recess 73 are formed at positions directly opposite each other across the accommodation space of the inner cylinder 5, and have shapes that are point-symmetrical with respect to the axis C of the outer cylinder 7. The second recess 72 and the fourth recess 74 are formed at positions directly opposite each other across the accommodation space of the inner cylinder 5, and have shapes that are point-symmetrical with respect to the axis C of the outer cylinder 7.

[0040] [First recess] The first recess 71 is provided corresponding to the tumbler 6 of the first tumbler group 61, and has a tumbler locking surface 71a, a first tumbler abutment surface 71b connected to the tumbler locking surface 71a, and a tumbler guide surface 71c connected to the first tumbler abutment surface 71b. The first recess 71 is configured as a recess recessed radially outward by arranging the tumbler locking surface 71a and the tumbler guide surface 71c to sandwich the first tumbler abutment surface 71b between these surfaces, and forms a first receiving recess that receives a part of the tumbler 6 when the operation knob 4 is located at the first position in the initial state (see FIG. 9(a)).

[0041] The tumbler locking surface 71a functions as a rotation restricting portion that restricts counterclockwise rotation of the inner cylinder 5 relative to the outer cylinder 7. This tumbler locking surface 71a is configured to abut (lock) with a part (end) of the tumbler 6 located in the first recess 71, and restricts (positions) the counterclockwise movement of the inner cylinder 5 in the initial state of the cylinder lock 3.

[0042] The first tumbler contact surface 71b is configured to come into contact with a part (the tip) of the tumbler 6 located in the first recess 71, and to support the tumbler 6 in contact therewith.

[0043] The tumbler guide surface 71c functions as a rotation allowing portion that allows the clockwise rotation of the inner cylinder 5 relative to the outer cylinder 7. This tumbler guide surface 71c is connected to the first tumbler abutment surface 71b and is formed as an inclined surface that is inclined and extends inward toward the second recess 72. In other words, this tumbler guide surface 71c is configured as an inclined guide surface that allows the inner cylinder 5 to move in the clockwise direction by rotating the operation knob 4 while guiding the tumbler 6 attached to the inner cylinder 5 to the second recess 72 in the initial state (unlocked state) of the cylinder lock 3.

[0044] When the operating knob 4 is rotated to rotate the inner tube 5 clockwise relative to the outer tube 7, a part (end) of the tumbler 6 located in the first recess 71 moves radially inward of the inner tube 5 while being guided by the tumbler guide surface 71c, against the biasing force of the spring 63.

[0045] When the tumbler 6 passes through the tumbler guide surface 71c and reaches the second recess 72, the tumbler 6 moves radially outward by the biasing force of the spring 63 and is locked in the second recess 72. In this state, the locking member 8 (locking cam) engages with the receiving member 110a provided on the storage main body 110, and the locking state is established.

[0046] The inclined surface of the tumbler guide surface 71c can be formed in a straight line or a curved shape. It is preferable to form the inclined surface as a curved surface that continues to the edge of the second recess 72. By forming the inclined surface as such, it is possible to reduce the initial load (the load at the beginning of rotation) when the operation knob 4 starts to be operated, and also to smoothly guide the end of the tumbler 6 along the tumbler guide surface 71c.

[0047] [Second recess] The second recess 72 has a tumbler engagement surface 72a on one side located on the tumbler guide surface 71c side in the circumferential direction, a second tumbler abutment surface 72b connected to this tumbler engagement surface 72a on one side, and a tumbler engagement surface 72c on the other side connected to this second tumbler abutment surface 72b.

[0048] That is, the second recess 72 is configured such that the tumbler locking surface 72a on one side and the tumbler locking surface 72c on the other side are disposed to sandwich the second tumbler abutment surface 72b, thereby forming a recess that is recessed radially outward on each of these surfaces, and forms a second receiving recess that receives a part of the tumbler 6 when the operation knob 4 is located at the second position in the locked state (see FIG. 11(a)). This second recess 72 functions as a rotation restricting portion that restricts the relative rotation of the inner tube 5 with respect to the outer tube 7 by locking a part (end portion) of the tumbler 6 of the inner tube 5.

[0049] The tumbler locking surface 72a on one side is configured to abut (lock) with a part (end) of the tumbler 6 located in the second recess 72, restricting counterclockwise movement of the inner cylinder 5. The second tumbler abutting surface 72b is configured to abut with a part (tip) of the tumbler 6 located in the second recess 72, and abuts and supports the tumbler 6. The tumbler locking surface 72c on the other side abuts (locks) with a part (end) of the tumbler 6 located in the second recess 72, restricting clockwise movement of the inner cylinder 5.

[0050] [Third recess] The third recess 73 is provided corresponding to the tumbler 6 of the second tumbler group 62, and has a tumbler locking surface 73a, a third tumbler abutment surface 73b connected to the tumbler locking surface 73a, and a tumbler guide surface 73c connected to the third tumbler abutment surface 73b. The third recess 73 is configured as a recess recessed radially outward by arranging the tumbler locking surface 73a and the tumbler guide surface 73c so as to sandwich the third tumbler abutment surface 73b, and forms a first receiving recess that receives a part of the tumbler 6 when the operation knob 4 is located at the first position in the initial state (see FIG. 9(a)).

[0051] The third recess 73 has a shape that is point-symmetrical with respect to the first recess 71 and the axis C of the outer tube 7, and the tumbler locking surface 73a, the third tumbler abutment surface 73b, and the tumbler guide surface 73c of the third recess 73 are configured in the same manner as the tumbler locking surface 71a, the first tumbler abutment surface 71b, and the tumbler guide surface 71c of the first recess 71, respectively, so their description is omitted.

[0052] [Fourth recess] The fourth recess 74 has a tumbler locking surface 74a on one side located on the tumbler guide surface 73c side in the circumferential direction, a fourth tumbler abutment surface 74b connected to the tumbler locking surface 74a on one side, and a tumbler locking surface 74c on the other side connected to the fourth tumbler abutment surface 74b. In other words, the fourth recess 74 is configured such that the tumbler locking surface 74a on one side and the tumbler locking surface 74c on the other side are arranged to sandwich the fourth tumbler abutment surface 74b, thereby forming a recess that is recessed radially outward on each of these surfaces, and forms a second receiving recess that receives a part of the tumbler 6 when the operation knob 4 is located at the second position in the locked state (see FIG. 11(a)).

[0053] The fourth recess 74 has a shape that is point-symmetrical with respect to the second recess 72 and the axis C of the outer tube 7, and the tumbler locking surface 74a on one side of the fourth recess 74, the fourth tumbler abutment surface 74b, and the tumbler locking surface 74c on the other side are configured in the same manner as the tumbler locking surface 72a on one side of the second recess 72, the second tumbler abutment surface 72b, and the tumbler locking surface 72c on the other side, respectively, and therefore their description is omitted.

[0054] In this embodiment, the first recess 71, the second recess 72, the third recess 73, and the fourth recess 74 are provided on the inner peripheral surface of the outer cylinder 7, but this is not limited to the example. For example, when the tumbler 6 is composed of either the first tumbler group 61 or the second tumbler group 62, it may be composed of only the first recess 71 and the second recess 72, or only the third recess 73 and the fourth recess 74, correspondingly.

[0055] [Inner cylinder support surface] The inner cylinder support surfaces 75, 76 are formed between the second recess 72 and the third recess 73, and between the fourth recess 74 and the first recess 71, and are disposed at positions directly opposite each other across the accommodation space of the inner cylinder 5. Each of the inner cylinder support surfaces 75, 76 is formed into a substantially arcuate surface that supports the outer circumferential surface of the inner cylinder 5, and rotatably supports the outer circumferential surface of the inner cylinder 5. By supporting the inner cylinder 5 with these inner cylinder support surfaces 75, 76, the inner cylinder 5 can be stably rotated.

[0056] [Locking components] 6, the locking member 8 is, for example, made of a flat metal member and configured as a cam member (locking cam) that locks the door 120 of the luggage storage bin 100. Specifically, when the door 120 of the luggage storage bin 100 is in a "closed state" in which the door is closed, the tip of the locking member 8 (locking cam) engages with a receiving member 110a (see FIG. 11(a)) provided on the storage bin main body 110, thereby putting the door 120 of the luggage storage bin 100 into a "locked state."

[0057] At the rear end of the locking member 8 (locking cam), there is formed an attachment hole 8a into which the shaft portion 54 provided at the rear end of the inner cylinder 5 can be inserted. Also, this attachment hole 8a is formed with a recess 8b that engages with a protrusion 54a (see FIG. 7(b)) provided so as to protrude outward from the outer circumferential surface of the shaft portion 54 of the inner cylinder 5.

[0058] When attaching the locking member 8 (locking cam) to the inner cylinder 5, the shaft portion 54 of the inner cylinder 5 is inserted into the attachment hole 8a of the locking member 8 (locking cam), and the protrusion 54a on the shaft portion 54 is fitted into the recess 8b of the attachment hole 8a, and then the locking member 8 (locking cam) is fastened using a washer 9 and a nut 10. This fastening causes the locking member 8 (locking cam) to be attached and fixed to the inner cylinder 5 so as to rotate integrally with the inner cylinder 5. The shaft portion 54 has a male thread formed on its outer circumferential surface, which is screwed into the female thread of the nut 10.

[0059] The locking member 8 (locking cam) changes its position via the inner cylinder 5 when the operation knob 4 is rotated. When the operating knob 4 is in the first position in the initial state (see Figure 9(a)), that is, when the tumbler 6 is located in the first receiving recess of the first recess 71 and the third recess 73 of the outer tube 7, a delivery person (e.g., a courier) can freely switch the position of the locking member 8 (locking cam) from the unlocked position to the locked position by rotating the operating knob 4 without using a key A.

[0060] Furthermore, when the operating knob 4 is in the second position in the locked state (see FIG. 11(a)), that is, when the tumbler 6 is in the second receiving recess of the second recess 72 and the fourth recess 74 of the outer cylinder 7, a part of the tumbler 6 is engaged with the second receiving recess of the second recess 72 and the fourth recess 74 of the outer cylinder 7, so that the relative rotation of the inner cylinder 5 with respect to the outer cylinder 7 is restricted, and as a result, the operating knob 4 is in a locked state. The rotation operation of the operating knob 4 is restricted, and the change in the position of the locking member 8 (locking cam) is restricted.

[0061] (Example of use of luggage lockers equipped with locking devices) Next, an example of use of the luggage storage 100 equipped with the locking device 1 will be described. FIG. 9(a) is a front schematic diagram showing the unlocked state (initial state) of the locking device according to the embodiment of the present invention, and FIG. 9(b) is an explanatory diagram explaining the positional relationship between the tumblers (first tumbler group) and the outer cylinder in the unlocked state (initial state). FIG. 10(a) is a front schematic diagram showing the state during operation of the locking device, and FIG. 10(b) is an explanatory diagram explaining the positional relationship between the tumblers (first tumbler group) and the outer cylinder in the state during operation. FIG. 11(a) is a front schematic diagram showing the locked state of the locking device, and FIG. 11(b) is an explanatory diagram explaining the positional relationship between the tumblers (first tumbler group) and the outer cylinder in the locked state.

[0062] <Initial state (unlocked)> In the initial state of the locking device 1 shown in Fig. 9(a)(b), the luggage storage 100 is empty and can receive luggage (delivery) from a deliverer such as a courier at any time. As shown in Fig. 9(a), in this initial state, the position mark 45 of the operation knob 4 is aligned with the character 27a of "OPEN" and the position mark 27c displayed on the front wall member 21 of the housing 2, so that the deliverer can visually confirm that the door 120 of the luggage storage 100 is in an "unlocked state" in which it can be opened and closed. In other words, it is easy to understand that the delivered luggage can be stored (handed over) in the luggage storage 100.

[0063] In this initial state, the luggage storage 100 is in an "unlocked state" with the door 120 in a "closed state" and the locking member 8 (locking cam) disengaged from the receiving member 110a (unlocked state) (see FIG. 9(a)). Specifically, as shown in FIG. 9(b), a part (end) of the tumbler 6 (61) attached to the inner tube 5 is located within the first recess 71 of the outer tube 7, allowing the operation knob 4 to be operated, and the locking member 8 (locking cam) is not engaged with the receiving member 110a provided on the main body of the luggage storage 100, allowing the door 120 to be opened.

[0064] In addition, in order to make the state of the tumblers 6 easier to understand, Figure 9 (b) only illustrates the tumblers 6 of the first tumbler group 61, and omits the illustration of the tumblers 6 of the second tumbler group 62. However, in this initial state, a portion (end) of the tumbler 6 of the second tumbler group 62 is positioned within the third recess 73 of the outer tube 7.

[0065] <Storing luggage in the luggage storage> The deliverer grasps the handle 26 of the locking device 1 to open the door 120 ("open state") and stores the package (delivery item) in the storage space inside the storage cabinet main body 110. Since the door 120 is in the "unlocked state", it can be easily put into the "open state" by simply pulling the handle 26 towards the front. After storing the package inside the storage cabinet main body 110, the deliverer closes the door 120 to put it into the "closed state."

[0066] <Locking operation> Next, the deliverer rotates the operation knob 4 of the lock device 1 with his / her fingers (see FIG. 10(a)). The deliverer only needs to rotate (turn) the operation knob 4 in the operation direction (clockwise) indicated by the operation mark 27b displayed on the front wall member 21 of the housing 2.

[0067] As shown in FIG. 10(b), when the operating knob 4 is rotated to rotate the inner tube 5 clockwise relative to the outer tube 7, a part (end) of the tumbler 6 located in the first recess 71 moves radially inward (in the direction of the arrow in FIG. 10(b)) of the inner tube 5 while being guided by the tumbler guide surface 71c against the biasing force of the spring 63 (see FIG. 6). In addition, although the tumbler 6 of the second tumbler group 62 is not shown in Figure 10 (b), during this locking operation, a portion (end) of the tumbler 6 of the second tumbler group 62 moves radially inward of the inner tube 5 while being guided by the tumbler guide surface 73c of the third recess 73.

[0068] Furthermore, as the rotation of the operating knob 4 progresses (see Figure 11(a)), the tumbler 6 passes through the tumbler guide surface 71c and reaches the second recess 72. As shown in Figure 11(b) , the tumbler 6 moves radially outward (in the direction of the arrow in Figure 11(b)) due to the biasing force of the spring 63 (see Figure 6) and is locked within the second recess 72. At the same time, the locking member 8 (locking cam) engages with the receiving member 110a provided on the main body of the luggage storage 100 to enter the locked state (see Figure 11(a)).

[0069] In other words, a part (end) of the tumbler 6 is engaged within the second recess 72 of the outer tube 7, restricting the relative rotation of the inner tube 5 with respect to the outer tube 7 and preventing the operation of the operating knob 4. Furthermore, the locking member 8 (locking cam) is engaged with the receiving member 110a provided on the main body of the luggage storage bin 100, resulting in a "locked state" in which the door 120 cannot be opened.

[0070] In addition, although the tumbler 6 of the second tumbler group 62 is not shown in Figure 11 (b), in this locked state, a portion (end) of the tumbler 6 of the second tumbler group 62 is positioned and engaged within the fourth recess 74 of the outer tube 7.

[0071] <Unlocking operation> To unlock the locked lock device 1, key A is used for the unlocking operation. First, key A is inserted into the key insertion hole 44 of the operation knob 4 in the locked state shown in Fig. 11(a). When key A is inserted through the key insertion hole 44 into the keyhole 51 of the inner cylinder 5 and the key insertion hole 6a of the tumbler 6, the tumbler 6 is completely drawn into the tumbler attachment hole 53 of the inner cylinder 5. As a result, the engagement between the tumbler 6 and the second recess 72 and the fourth recess 74 is released, and the inner cylinder 5 can rotate relative to the outer cylinder 7.

[0072] Next, by rotating key A counterclockwise by 90 degrees, the operating knob 4 and inner cylinder 5 also rotate counterclockwise by 90 degrees. After that, by pulling out key A, the lock device 1 returns to the initial position shown in Figures 9(a) and (b). In other words, a part (end) of the tumbler 6 attached to the inner cylinder 5 is located in the first recess 71 and the third recess 73 of the outer cylinder 7, and the locking member 8 (locking cam) is in an "unlocked state" where it is not engaged with the receiving member 110a provided on the main body of the luggage storage 100. In addition, in FIG. 9(b), the tumblers 6 of the second tumbler group 62 are not shown.

[0073] Thereafter, the user grasps the handle 26 of the locking device 1 to open the door 120, removes the package (delivery) from the storage main body 110, and then closes the door 120, thereby completing the package receiving process.

[0074] As described above, the locking device 1 for luggage storage according to the present invention can be locked simply by turning the operating knob 4 without using a key A, and the locking structure is simple and not complicated, so that it is easy to operate and durable.

[0075] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate without departing from the gist of the present invention.
