Mode for Carrying Out the Invention

[0010] <First Embodiment> Hereinafter, the first embodiment of the present invention will be described with reference to the drawings.

[0011] In FIG. 1, reference numeral 1 indicates a dial tablet according to the first embodiment of the present invention.

[0012] This dial tablet 1 is used for a rental locker or the like used by an unspecified number of people, and has a case 2 with an open front side and a cover 3 that covers the opening of this case 2, and is attached to the door of the locker via a mounting bracket 4.

[0013] Further, an operation knob (operation part) 5 for performing an opening / closing operation of the door and, for example, four dials 31 for unlocking project from the cover 3.

[0014] The dial 31 has a dial operation part 32 that partially projects from the cover 3 and a dial display part 33 that is formed coaxially and integrally with this dial operation part 32.

[0015] On the circumferential surface of this dial display section 33, dial displays such as numbers from 0 to 9 are displayed at equal intervals, for example.

[0016] Furthermore, on the cover, there are an opening 7 for the operation knob 5 to protrude, an opening 8 for the dial operation section 32 to protrude, and a window 9 through which a key code display section (details will be described later) 34 for displaying a key code such as a QR code (registered trademark), which is a two-dimensional code for example, can be seen.

[0017] Adjacent to the opening 8, there is a window 10 through which the dial display of the dial display section 33 can be seen.

[0018] Also, on the back side of the cover 3, there is a catch 12 provided that rotates in conjunction with the operation knob 5.

[0019] That is, as shown in FIGS. 2 and 3, the operation knob 5 is formed in a cylindrical shape and is fitted into the knob cover 13 so as to rotate integrally with the knob cover 13.

[0020] The fitting of this operation knob 5 and the knob cover 13 is prevented from coming off by covering and pressing with the cover 3.

[0021] Also, on the knob cover 13, a male screw 14 passes through a slide cover (described later) 15 and the case 2 and protrudes to the back side of the case 2. The catch 12 is attached to this protruding male screw 14, and when the operation knob 5 is rotated, the catch 12 rotates.

[0022] Furthermore, on the knob cover 13, a regulating projection 16 protrudes at a position eccentric from the male screw 14. On the other hand, an arcuate long hole 17 into which the regulating projection 16 fits is formed in the slide cover 15, whereby the rotation range of the operation knob 5 is regulated.

[0023] Therefore, as shown in FIG. 4, the stopper fitting 12 is configured to be rotatable from an upright state to a fallen state. As shown in FIGS. 5 and 6, when locking, it is locked to a locking portion 18 provided on the housing of the locker in the fallen state to prevent the door from being opened or closed. When unlocking, the locking with the locking portion 18 is released in the upright state to enable the opening and closing of the door.

[0024] Also, a stopper fitting control button 20 is provided on the back side of the case 2 and is biased by a spring 19 attached to the slide cover 15 to protrude toward the back side of the case 2.

[0025] This stopper fitting control button 20 restricts the rotation of the stopper fitting 12 from the upright state to the fallen state when the door is opened and protrudes from the case 2. When the door is closed, it is pushed into the case 2 by a pressing plate 21 provided on the housing of the locker, enabling the rotation of the stopper fitting 12 from the upright state to the fallen state.

[0026] Since this pressing plate 21 is positioned in the gap between the case 2 and the stopper fitting 12 when the door is closed, the door cannot be opened unless the stopper fitting 12 is in the upright state.

[0027] That is, in the fallen state or inclined state of the stopper fitting 12, the stopper fitting 12 is caught by the pressing plate 21, and the door cannot be opened.

[0028] Furthermore, returning to FIGS. 2 and 3, inside the case 2, there is a key code dial 41 having a plurality of unlocking patterns for unlocking, a push button (key code selection unit) 42 for selecting, as an unlocking pattern that contributes to unlocking, one of the plurality of unlocking patterns of this key code dial 41, a dial key 43 having a corresponding pattern corresponding to the plurality of unlocking patterns of the key code dial 41, a dial 31 for selecting a corresponding pattern corresponding to the unlocking pattern that contributes to the unlocking of the key code dial 41 among the corresponding patterns of this dial key 43, and a locking mechanism unit 44 is provided that enables the operating knob 5 to be unlocked when the corresponding pattern of the dial key 43 matches the unlocking pattern selected by the push button 42, and enables the operating knob 5 to be locked in a non-matching state.

[0029] This locking mechanism unit 44 has a key code shaft 45, and the key code shaft 45 is rotatably and axially slidably attached to a frame body 46 fixed inside the case 2.

[0030] For example, four key code dials 41 are fixed to this key code shaft 45 at predetermined intervals.

[0031] That is, each of these key code dials 41 is fixed to the key code shaft 45 by a spring pin 47 so as to be non-rotatable and non-axially slidable with respect to the key code shaft 45.

[0032] On the circumferential surface of each of the key code dials 41, for example, 10 key code patterns (unlocking patterns) are formed in a concavo-convex shape.

[0033] Also, a ratchet 49 that engages with a latch 48 connected to the push button 42 is fixed to this key code shaft 45 and is configured to rotate integrally with the key code shaft 45.

[0034] That is, the push button 42 is fitted into the operating knob 5 so that its head can protrude from the operating knob 5. It rotates integrally with the operating knob 5 and is configured to be slidable in the axial direction with respect to the operating knob 5.

[0035] Further, the push button 42 is formed in a cylindrical shape and is biased in the direction of protruding from the operating knob 5 by a spring 50 housed in this cylindrical portion.

[0036] When this push button 42 is pushed in, the latch 48 engages with the ratchet 49, and the ratchet 49 is rotated by a predetermined angle together with the key code shaft 45.

[0037] That is, when there are 10 key code patterns on the key code dial 41, it is configured to rotate only 1 / 10 of a revolution.

[0038] Furthermore, a latch 11 attached to the cover 3 is engaged with the latch 48.

[0039] That is, this latch 11 is biased by a spring (not shown) in the direction of engaging with the latch 48 and has a stop surface and an inclined surface.

[0040] The latch 48 prevents the operating knob 5 from rotating in the unlocking direction from the locked state by abutting against the stop surface of the latch 11.

[0041] Also, when the push button 42 is pushed in, contact with the stop surface of the latch 11 is avoided, thereby enabling the operating knob 5 to rotate in the unlocking direction.

[0042] Furthermore, the latch 48 is configured to push in the latch 11 against the biasing force of the spring while riding up the inclined surface of the latch 11 as the operating knob 5 rotates in the locking direction.

[0043] Furthermore, a fan-shaped flange 51 extending radially over a predetermined angle is connected to the circumferential surface of the push button 42 and is adapted to engage with a latch 53 slidably attached to the frame body 46.

[0044] That is, this latch 53 is biased toward the push button 42 by a spring 52, and when the push button 42 is pushed in the locked state, it engages with the flange 51 and holds the push button 42 in the pushed-in state.

[0045] Also, when the operation knob 5 is rotated in the unlocking direction, this latch 53 is disengaged from the flange 51.

[0046] Furthermore, this flange 51 is adapted to engage with a stopper 54 fixed to the frame body 46.

[0047] That is, when the operation knob 5 is rotated in the unlocking direction, the stopper 54 engages with the flange 51 at the same time as the engagement between the flange 51 and the latch 53 is released. When the operation knob 5 is rotated to the unlocked state, the engagement with the flange 51 is released and the push button 42 returns to its original state.

[0048] Furthermore, the locking mechanism portion 44 is rotatably and axially slidably attached to the frame body 46 and has a dial shaft 61.

[0049] As shown in FIG. 7, four dials 31 are rotatably attached to this dial shaft 61 corresponding to the four key code dials 41.

[0050] A dial key 43 is integrally fixed to the side of each dial 31 opposite to the dial display portion 33.

[0051] On the circumferential surface of each of the dial keys 43, a corresponding pattern corresponding to the key code pattern of the key code dial 41, that is, a concavo-convex shape that can mesh with the concavo-convex shape of the key code pattern, is formed.

[0052] At the end of this dial shaft 61, a slider 62 is attached, which is slidably clamped by the case 2 and the slide cover 15.

[0053] A guide groove 63 is formed in this slider 62, into which a regulating projection 16 provided on the knob cover 13 is slidably fitted.

[0054] This guide groove 63 is formed in a direction orthogonal to the sliding direction of the slider 62.

[0055] When the operation knob 5 rotates, the rotational movement of the regulating projection 16 is converted into a linear movement of the slider 62 by the guide groove 63, and the slider 62 slides axially together with the dial shaft 61.

[0056] Furthermore, as shown in FIG. 8, four wedge-shaped projections 64 are provided on the dial shaft 61 corresponding to the four dials 31.

[0057] On the other hand, a cylindrical cam 65 that engages with the wedge-shaped projection 64 is formed on the inner peripheral surface of the dial 31.

[0058] When the wedge-shaped projection 64 is not engaged with the cylindrical cam 65, the dial 31 is rotatable relative to the dial shaft 61.

[0059] Also, when the dial shaft 61 slides and the wedge-shaped projection 64 fits and engages with the cylindrical cam 65, the dial 31 rotates and is configured to stop at a predetermined rotational position relative to the dial shaft 61.

[0060] That is, when the operation knob 5 rotates and the stop fitting 12 is in the upright state at the unlocking position, the dial display of the dial display unit 33 visible through the window 10 is set to, for example, "0000".

[0061] Note that the periphery of the dial operation part 32 of the dial 31 is formed in a wavy shape.

[0062] A leaf spring 122 is provided in pressure contact with the periphery of the dial operation part 32, and thus the dial display part 33 is configured to stop at a position where it can be seen from the window 10.

[0063] Also, the leaf spring 122 is configured to be pushed up in a direction away from the dial operation part 32 by the dial control plate 132, thereby making it easier for the dial 31 to rotate.

[0064] Note that this dial control plate 132 is configured to be pushed up by a convex part 133 provided on the outer peripheral surface of the operation knob 5.

[0065] Furthermore, as shown in FIG. 9, a slide block 71 is fitted to the key code shaft 45 so as to be movable in a direction orthogonal to the axial direction of the key code shaft 45, and is biased in the direction of the slider 62 by a spring 80.

[0066] This slide block 71 is sandwiched between a pair of flanges 121 fixed to the key code shaft 45 and is configured not to be movable in the axial direction of the key code shaft 45.

[0067] Also, this slide block 71 includes a block body 73 having an elliptical cross-sectional hole 72 into which the key code shaft 45 is externally fitted so as to be movable in a direction orthogonal to the axial direction.

[0068] This block body 73 has an engaging part 74 that engages with the slider 62 and an opening 75 for fitting the key code shaft 45 into the hole 72 from the radial direction.

[0069] When the slider 62 slides in the unlocking direction, this engaging portion 74 has a contact surface 111 that contacts the slider 62, and when the slider 62 slides in the locking direction, it engages with the slider 62 and has an inclined surface 112 that pushes down the slide block 71 in a direction away from the slider 62.

[0070] Also, a retaining member 76 that prevents the key code shaft 45 from coming out of the hole 72 through the opening 75 is attached to the block body 73.

[0071] This retaining member 76 is formed with a recess 78 into which a protrusion 77 fixed to the cover 3 is fitted, and an inclined surface 79 with which the protrusion 77 engages is provided on the inner peripheral portion of this recess 78.

[0072] When the slider 62 moves, the slider 62 presses the contact surface 111 of the engaging portion 74 and moves the key code shaft 45 together with the slide block 71 in a direction in which the key code dial 41 meshes with the dial keys 43. Along with this movement, the protrusion 77 and the inclined surface 79 engage with each other, and the slide block 71 moves in a direction away from the slider 62. When the engagement between the slider 62 and the engaging portion 74 is disengaged, the slide block 71 returns in the direction of the slider 62.

[0073] Furthermore, a display dial 81 that encrypts and displays an unlocking pattern that contributes to unlocking the key code dial 41 is attached adjacent to the key code dial 41 on the key code shaft 45.

[0074] That is, on the peripheral surface of this display dial 81, a key code display unit 34 that encrypts and displays key code displays corresponding to the key code patterns of the key code dial 41, for example, 10 fixed numbers (unlocking numbers), such as a two-dimensional code, is provided.

[0075] This two-dimensional code is configured such that if it is a smartphone that the user has accessed and registered in advance to the URL of the two-dimensional code, the unlocking number can be obtained.

[0076] Further, this display dial 81 is axially slidably attached to the key code shaft 45.

[0077] That is, as shown in FIG. 10, a long hole 83 that is long in the axial direction is formed in the key code shaft 45. By engaging a spring pin 84 with this long hole 83, the display dial 81 is non-rotatable and axially slidable with respect to the key code shaft 45.

[0078] Also, the movement of the display dial 81 in the direction opposite to the key code dial 41 is restricted by the frame body 46.

[0079] Furthermore, a spring 82 is interposed between the display dial 81 and the key code dial 41 to bias the display dial 81 and the key code dial 41 in opposite directions, that is, to bias the key code dial 41 and the key code shaft 45 in the direction opposite to the display dial 81.

[0080] Furthermore, the key code display portion 34 of the display dial 81 is configured to be in an exposed state and a shielded state by the shutter mechanism portion 131.

[0081] That is, a shutter ratchet 85 is attached to the key code shaft 45 on the side opposite to the key code dial 41 with respect to the display dial 81.

[0082] This shutter ratchet 85 is non-rotatable and axially slidable with respect to the key code shaft 45 by engaging a spring pin 87 with a long hole 83 that is long in the axial direction formed in the key code shaft 45.

[0083] Therefore, the key code dial 41, the key code shaft 45, the ratchet 49, the display dial 81, and the shutter ratchet 85 are configured to rotate integrally.

[0084] On one side, a shutter 91 for opening and closing the window 9 is provided on the back side of the cover 3.

[0085] This shutter 91 is slidably supported by a shutter retainer 92 fixed to the cover 3.

[0086] Also, a support shaft 93 protrudes from the back surface of the cover 3, and a shutter movable plate 94 is rotatably supported on this support shaft 93.

[0087] A protrusion 95 is provided on one end side of the shutter movable plate 94, and a groove 96 into which this protrusion 95 slidably engages is formed in the shutter 91.

[0088] And it is configured such that the rotational movement of the shutter movable plate 94 is converted into the sliding movement of the shutter 91.

[0089] Furthermore, a plate-shaped contact portion 97 that contacts one end portion of the dial shaft 61 is provided on the other end side of the shutter movable plate 94.

[0090] Furthermore, this shutter movable plate 94 is rotationally biased by a spring 98 in the direction in which the contact portion 97 contacts the dial shaft 61, that is, in the direction in which the shutter 91 opens the window 9.

[0091] Furthermore, a shutter control shaft 101 is provided near the shutter movable plate 94.

[0092] One end of this shutter control shaft 101 is rotatably supported by the case 2, and it has a latch portion 102 that engages with the shutter ratchet 85 at the rotating end which is the other end.

[0093] Also, this shutter control shaft 101 is rotationally biased by a spring 103 in the direction in which the latch portion 102 engages with the shutter ratchet 85.

[0094] Furthermore, this shutter control shaft 101 has a convex portion 104 at an intermediate part, with which an abutting portion 97 of the shutter movable plate 94 engages.

[0095] When the abutting portion 97 of the shutter movable plate 94 is pushed by the dial shaft 61 and rotates, this convex portion 104 has an inclined portion 105 that engages with the abutting portion 97, and a locking portion 106 that holds the abutting portion 97 in a state where the window 9 of the shutter 91 is closed.

[0096] When the shutter movable plate 94 is pushed by the dial shaft 61 and engages with the inclined portion 105, the shutter control shaft 101 rotates. When it is further pushed and the engagement is released, the shutter control shaft 101 returns, and the locking portion 106 holds the abutting portion 97 in a state where the window 9 of the shutter 91 is closed.

[0097] Also, when the latch portion 102 of the shutter control shaft 101 is pushed by the shutter ratchet 85, the engagement between the shutter movable plate 94 and the locking portion 106 is released, and the shutter movable plate 94 returns.

[0098] Next, in the above configuration, the locking operation will be described.

[0099] First, open the locker door and put in the luggage.

[0100] At this time, as shown in FIG. 11, the dial shaft 61 slides axially together with the slider 62, and the wedge-shaped protrusion 64 fits into the cylindrical cam 65, so that the four dials 31 display and hold "0000" with all the dial display portions 33 being, for example, "0".

[0101] Also, the abutting portion 97 of the shutter movable plate 94 is held by the locking portion 106 of the shutter control shaft 101, and the shutter 91 closes the window 9.

[0102] Furthermore, since the locking fitting control button 20 protrudes from the case 2, the locking fitting 12 hits the locking fitting control button 20 and the operating knob 5 does not rotate.

[0103] Next, as shown in FIG. 12, when the door is closed, the pressing plate 21 on the housing side presses the locking fitting control button 20 into the case 2.

[0104] Thereby, the operation of the operating knob 5 in the locking direction becomes possible.

[0105] When the operating knob 5 is operated in the locking direction, the regulating projection 16 rotates, the dial shaft 61 slides together with the slider 62, the wedge projection 64 disengages from the cylindrical cam 65, and the dial 31 becomes rotatable.

[0106] Also, the slide block 71 is displaced against the spring 80 as the slider 62 slides.

[0107] Next, as shown in FIG. 13, when the operating knob 5 is rotated to the locked position, the locking fitting 12 is locked to the locking portion 18 on the housing side and the locking is completed.

[0108] At this time, the engaging portion 74 of the slide block 71 is in a state of being locked to the slider 62.

[0109] When unlocking is operated in this state, since the dial display portion 33 of the dial 31 is "0000", the key code dial 41 and the dial key 43 do not mesh, the dial shaft 61 cannot slide either, and the operating knob 5 does not rotate.

[0110] At this time, the shutter 91 is closed.

[0111] Next, the unlocking operation will be described.

[0112] When the push button 42 is pressed from the locked state shown in FIG. 13, as shown in FIG. 14, the latch 48 presses down the ratchet 49 and the key code shaft 45 rotates by 1 / 10 turn (36°).

[0113] At the same time, the display dial 81 also rotates, and the key code display on the key code display section 34 is changed.

[0114] Furthermore, at the same time, the shutter ratchet 85 also rotates, pressing down the latch portion 102 of the shutter control shaft 101.

[0115] As a result, the engagement between the contact portion 97 of the shutter movable plate 94 and the convex portion 104 of the shutter control shaft 101 is released, the shutter 91 opens, and the key code display on the key code display section 34, for example, the two-dimensional code, is exposed.

[0116] At this time, the flange 51 fixed to the push button 42 is hooked on the latch 53, and the push button 42 is held in the pushed state.

[0117] Next, by using a smartphone that has accessed and registered in advance to the URL of the two-dimensional code and reading the two-dimensional code that is the key code display on the key code display section 34, the unlocking number is displayed on the smartphone, and thus the unlocking number can be obtained.

[0118] Next, as shown in FIG. 15, the numbers that are the dial display on the dial display section 33 are adjusted to match the unlocking number.

[0119] Next, when the operation knob 5 is rotated by a predetermined angle in the unlocking direction, the slider 62 slides to the right in the figure. Along with this, the slide block 71 moves downward to the lower right in the figure by the protrusion 77, and the key code dial 41 meshes with the dial key 43.

[0120] In this state, the stop fitting 12 comes off from the locking portion 18, but the pressing plate 21 gets in the way and the door does not open.

[0121] Next, as shown in FIG. 16, when the operation knob 5 is further rotated in the unlocking direction, the slide block 71 comes off from the slider 62, and the key code shaft 45 returns to its original position.

[0122] Next, as shown in Fig. 17, when the operating knob 5 is further rotated in the unlocking direction, the flange 51 disengages from the latch 53, and the push button 42 returns.

[0123] At the same time, the dial shaft 61 presses the contact portion 97 of the shutter movable plate 94, and the shutter 91 starts to close.

[0124] At the same time, the dial control plate 132 is pushed up by the convex portion 133 of the operating knob 5, whereby the leaf spring 122 separates from the dial 31, and the dial 31 becomes easier to rotate.

[0125] Next, as shown in Fig. 18, when the operating knob 5 is further rotated and the stop fitting 12 is in the upright state, the stop fitting 12 separates from the presser plate 21, and the door can be opened.

[0126] At the same time, the dial shaft 61 slides together with the slider 62, and the wedge projection 64 engages with the cylindrical cam 65, so that the dial display of the dial display portion 34 becomes "0000".

[0127] Also, the contact portion 97 of the shutter movable plate 94 is pushed by the dial shaft 61, and the shutter 91 closes.

[0128] Furthermore, the contact portion 97 catches on the convex portion 104 of the shutter control shaft 101, and the shutter 91 is held in the closed state.

[0129] According to the above configuration, the unlocking numbers are, for example, ten fixed numbers that are repeatedly used, and there is no need to set an arbitrary one fixed number (password number) or one-time number (password number) as in the prior art. Moreover, since there is no possibility of forgetting the password number, the locking operation and unlocking operation can be easily performed.

[0130] Also, since the unlocking number is displayed on the smartphone by reading the two-dimensional code with the smartphone that has accessed and registered the URL of the two-dimensional code in advance, it can be easily obtained.

[0131] Furthermore, in order to set the unlocking number (fixed number) by combining the key code dial 41 and the dial key 43, by preparing a plurality of patterns of the key code dial 41 and the dial key 43, the unlocking number (fixed number) can be increased.

[0132] Furthermore, a stop fitting control button 20 is provided so that the locking operation can be performed with the door closed, thus preventing the accidental locking operation when the door is open.

[0133] In the above embodiment, the unlocking number (fixed number) of four digits is set by combining the four key code dials 41 and the dial key 43. However, the present invention is not limited to this, and it is of course possible to set the unlocking number (fixed number) of one digit by combining one key code dial 41 and the dial key 43.

[0134] Also, in the above embodiment, the key code display shown on the key code display unit 34 is a two-dimensional code such as a QR code. However, the present invention may also be a one-dimensional code such as a bar code or a symbol.

[0135] The disclosure of the present invention described above can be summarized at least in the following matters.
