(Outline of the present invention)
The present invention makes it possible to use a conventional lock, which is locked and unlocked with a metal key, as an electronic lock by attaching an unlocking assisting device to a door provided with a lock having a thumb turn. Key types can be widely used, but some keys cannot be used.

  Since the thumb turn is on the indoor side of the door 101, the unlocking assisting device 102 is also installed on the indoor side. When the wireless communication unit of the unlocking assisting device 102 receives the unlocking signal through the door, the unlocking assisting device 102 is driven based on the unlocking signal, and the thumb turn knob is rotated to unlock the unlocking signal. Done. The unlock signal can be transmitted by executing an application for transmitting the unlock signal on the mobile terminal 103 such as a smartphone, a tablet, or a dedicated remote controller. For example, communication can be performed by Bluetooth such as Bluetooth (registered trademark) Low Energy (BLE) or ZigBee (registered trademark) (see FIG. 1). When using ZigBee, the mobile terminal 103 is also required to have a communication function using ZigBee. For example, a smartphone cannot be used as the mobile terminal 103 at present, and the versatility is reduced. Not a few. Because of low power consumption, energy saving of the unlocking assisting device can be achieved.

  The unlocking signal can be generated based on the unlocking authority recorded on each portable terminal about which unlocking assisting device can be driven. The unlocking authority that can be recorded in each mobile terminal can be managed by a management server with which each mobile terminal can communicate. For example, it is possible to impose a date / time, a time zone limitation, a frequency limit, and the like. Alternatively, the unlocking authority can be given only to specific friends on the SNS. From the viewpoint of security, the unlocking signal can be configured not to unlock even if the unlocking signal is intercepted and the same signal is reproduced.

  The unlocking assisting device 102 can include a sensor that detects contact or approach of an object to the housing. In this case, the unlocking assisting device 102 can rotate the thumb-turn knob based on a detection signal indicating that the sensor has detected an object, and unlocking when moving from the room to the outside is facilitated. . A display unit such as a touch panel display may be provided in the casing of the unlocking assisting device 102 and the display unit may be used as a pressure sensor. In addition, a change in capacitance when an object comes into contact or approaches, a tactile switch that is turned on / off by pressing, or the like can also be used.

  When actually trying to attach such an unlocking assisting device, there are cases where the unlocking assisting device and the thumb turn do not mesh well due to various types of thumb turns. In the present invention, by arranging the adjusting member around at least a part of the thumb turn cylinder, it is possible to suppress the mounting error between the thumb turn and the unlocking assisting device. Significantly promote the spread of tablets.

(First embodiment)
FIG. 2A shows a back view of the unlocking assisting device according to the embodiment of the present invention, and FIG. 2B shows a cross-sectional view along the line BB. In FIG. 2B, a thumb turn 200 having a knob 201 and a thumb turn cylinder 202 is also shown. The unlocking assisting device 210 is a lock assisting device having the thumbturn 200, and includes a recess 211 that covers the thumbturn 200, a housing member 212 that houses the knob 201 of the thumbturn 200 within the recess 211, and a drive that rotates the housing member 212. Part 213.

  The concave portion 211 is circular in the rear view, but it is necessary to change the shape according to the type of lock to be attached, and the concave portion 211 according to this embodiment has an appropriate shape as appropriate. Can be adopted. When the unlocking assisting device 210 is attached to the door, a portion where the distance from the door to the housing 214 is larger than other portions generally corresponds to the recess 211.

  The housing member 212 can be positioned by the protrusion 214 </ b> A included in the housing 214 of the unlocking assisting device 210 and can be disposed so as to be the bottom of the recess 211. The width T of the groove portion 212A that accommodates the knob 201 is wider than the thickness of the knob 201. However, if the gap with the knob 201 in the groove portion 212A is large, the accuracy of detecting the angle of the knob decreases. It is desirable to make it smaller. Also, in order to cope with a type of security thumb turn that rotates while pressing the button, the lock cannot be unlocked if the gap is large and the amount of pressing the button is small, and if touched, it will lead to a malfunction of the rotation. It is appropriate to control the distance of the knob 201 with an accuracy of ± 0.2 mm. As shown in FIG. 2C, the housing member 212 may be disposed closer to the thumbturn 200 than the protrusion 214A. At this time, the shape of the housing 214 including the protrusion 214A can be appropriately designed.

  The driving unit 213 that rotates the housing member 212 may also be disposed as illustrated, or may be disposed at another position in the housing 214. For example, an electric motor or the like can be used.

  The unlocking assisting device 210 of the present embodiment further includes an adjustment member 215 that reduces the gap D between the thumb turn drum 201 and the side surface 214B of the recess 211. By disposing the adjusting member 215 on at least a part of the periphery of the thumb turn barrel 202, the shift between the thumb turn 200 and the unlocking assisting device 210 can be suppressed, so that the unlocking assisting device 210 is easily attached to the door. Will be able to. As shown in FIG. 2D, the adjustment member 215 may be fixed not on the side surface 214B of the recess 211, or on the other side of the housing 214 such as the protrusion 214A together with the side surface 214B.

  In order for the housing member 212 to house the knob 201 and perform the rotation necessary for unlocking, alignment in the order of mm is often required, and the unlocking assisting device 210 is attached to the user. There is a risk of excessive trial and error. According to the present embodiment, by providing the adjustment member 215 for appropriately arranging the thumb turn 200, an attachment error can be suppressed, and the user can attach it even if his eyes are closed.

FIG. 3A shows the positional relationship between the groove portion of the housing member and the thumb turn knob according to the present embodiment. The groove 212A is indicated by a dotted line. Here, a case where the rotation axis of the knob 201 is located at the center of the thumb turn cylinder 202 is considered. Further, consider a case where the rotation shaft of the housing member 212 is located at the center of the groove 212A. The coordinates of the center position of the thumb turn cylinder 202 are (x ₁ , y ₁ ), and the coordinates of the center position of the groove 212A are (x ₂ , y ₂ ). Further, the thickness of the knob 201 is t, the length is l, the width of the groove 212A is T, and the length is L.

FIG. 3B shows an arrangement relationship when the groove 212A rotates 90 degrees in the arrangement relationship shown in FIG. 3A. In order that the knob 201 can be unlocked by 90 degrees, as shown in the figure, it is necessary that | x ₁ −x ₂ | +1/2 is L / 2 or less (condition 1). . Similarly, it is necessary that | y ₁ −y ₂ | + t / 2 is T / 2 or less (condition 2). As a premise, since the knob 201 must be able to be accommodated in the groove 212A, | x ₁ −x ₂ | + t / 2 is T / 2 or less (condition 3), | y ₁ −y ₂ | + 1 / 2 must be L / 2 or less (condition 4). The following is a summary.
(Condition 1) | x ₁ −x ₂ | + l / 2 ≦ L / 2
(Condition 2) | y ₁ −y ₂ | + t / 2 ≦ T / 2
(Condition 3) | x ₁ −x ₂ | + t / 2 ≦ T / 2
(Condition 4) | y ₁ −y ₂ | + l / 2 ≦ L / 2
For example, when the recess 211 is circular with a radius R, the maximum value of Δx (= x ₁ −x ₂ ) and Δy (= y ₁ −y ₂ ), where r is the radius of the thumb turn cylinder, as shown in FIG. 4A. Becomes R-r. In FIG. 4A, the side surface 214B of the recess 211 is also indicated by a dotted line. In the illustrated example, the shift of the knob 201 is large, the knob 201 cannot be accommodated in the groove 212A, and naturally the knob 201 cannot be rotated. The condition 3 is not satisfied.

Here, as shown in FIG. 4B, when the annular adjustment member 215 is fixed to the side surface 214B and the shape of the recess 211 is changed, the widths of the adjustment member 215 in the x-axis direction and the y-axis direction are set to w ₁ and w _2. As described above, the maximum values of the deviations Δx and Δy between the rotating shaft of the knob 201 and the rotating shaft of the housing member 212 are limited to Rrw ₁ and Rrw ₂ . Conditions 1 to 4 can be satisfied by appropriately designing the widths w ₁ and w ₂ . If the above condition is rewritten, w ₁ and w ₂ may be designed so as to satisfy the following expression.

| R−r−w ₁ | + l / 2 ≦ L / 2,
| R−r−w ₂ | + t / 2 ≦ T / 2,
| R−r−w ₁ | + t / 2 ≦ T / 2 and | R−r−w ₂ | + l / 2 ≦ L / 2
Consider specific examples. If the thickness t = 2 mm of the knob 201 and the width T = 6 mm of the groove 212A, for example,
| Y ₁ −y ₂ | + t / 2 ≦ T / 2,
That is,
| Y ₁ −y ₂ | ≦ T / 2−t / 2 = 2 mm
Therefore, the attachment in the y direction (vertical direction) must be performed to satisfy the above condition. It is extremely difficult for the user to install it manually within the range of such tolerances, and if it is not installed properly, the rotation operation stops halfway, and there is an unreasonable load on the lock or unlocking assisting device. This brings about such problems.

  Since such mounting accuracy is required, it is necessary to make the casing 214 and the adjustment member 212 partially transparent so as to provide a confirmation window, or to provide an opening so that the mounting can be performed while viewing. Although there is a possibility, if the user puts the thumb turn 200 in the recess 211 of the unlocking assisting device 210 by providing the adjusting member 215 according to the present embodiment, even if necessary, only a slight position adjustment is required. Installation can be completed. For example, in the present embodiment, even if the housing member 212 is disposed in the housing 214 such that the storage member 212 is invisible in front view and / or side view of the unlocking assisting device 210, the attachment is easy. Further, even if the housing 214, the adjustment member 215, and the like are opaque, the user can easily attach them. The entire adjustment member 215 is preferably disposed in the housing 214 at least in a front view of the unlocking assisting device 210.

  In FIGS. 4A and 4B, the adjustment member 215 is shown in an annular shape, but if the conditions 1 to 4 can be satisfied, the adjustment member 215 does not need to be constant, such as a crescent shape, a protrusion shape, or a polygonal shape. The shape can be adopted. In the case of a protrusion, for example, the protrusions can be three protrusions arranged at substantially equal intervals along the side surface 214B of the recess 211 (see FIG. 4C). In addition, although the description has been made on the assumption that the knob 201 is locked vertically and unlocked horizontally, the unlocking assisting device 210 of the present embodiment can naturally be applied to a lock whose portrait and landscape are reversed.

  Moreover, as shown to FIG. 5A, the case where the end of the recessed part 211 is open | released and is not closed is also considered. In such a case, assuming that the distance between the unreleased side surfaces is A (2R in the case of an arc), the maximum deviation of the knob 201 in that direction is A / 2-r. As shown in FIG. 5B, by providing the adjustment member 500, the maximum value of the shift in at least one direction can be limited. The user can install the unlocking assisting device 210 only by attaching in the direction in which the adjustment member 500 is arranged, and by slightly aligning in the direction in which the side surface orthogonal to the adjustment member 500 is not partially closed. Become. The shape of the adjustment member 500 is not limited to the shape shown in FIG. 5B, and an annular shape, a crescent shape, a protrusion shape, a rectangular shape, or the like can be used as described above.

  Ideally, if the shape of the recess 211 can be changed so that the shape of the thumb turn 200 to be attached satisfies the above conditions 1 to 4 by appropriately selecting the adjustment member 215, the user can make the thumb turn 200 the recess 211. Just install it so that it enters the position.

  In actual production, the gap D between the thumb turn cylinder 201 and the side surface 214B of the concave portion 211 is set to at least the side surface 214B due to the presence of the adjusting member 215 even if not strictly satisfying all of the above conditions 1 to 4. If it can be reduced even partly, trial and error at the time of installation of the user is greatly reduced. Therefore, such an adjustment member 215 also belongs to the technical scope of this embodiment.

  Although the above description has been made on the assumption that the thumb turn drum 202 is a circular lock, the present invention is not necessarily limited to this.

  2B and the like, the adjustment member 215 has been described as reducing the gap D between the thumb turn cylinder 201 and the side surface 214B of the recess 211, but the side surface 214B is clearly specified depending on the shape of the housing 214. It can be difficult. Even in such a case, by changing the shape of the recess 211 using the adjustment member 215 and suppressing the deviation between the rotation shaft of the knob 201 and the rotation shaft of the housing member 212, the attachment of the unlocking assisting device 210 is performed. It is the same that can be made easier.

(Second Embodiment)
In the first embodiment, the case where the rotation axis of the knob 201 is located at the center of the thumb turn cylinder 202 and the rotation axis of the housing member 212 is located at the center of the groove 212A has been considered. In some cases, the rotation axis of the knob 201 is at coordinates (x ₁ + a ₁ , y ₁ + b ₁ ), and the rotation axis of the housing member is at coordinates (x ₂ + a ₂ , y ₂ + b ₂ ). At this time, the conditions 1 to 4 shown in the first embodiment are as follows.
(Condition 1 ′) | (x ₁ + a ₁ ) − (x ₂ + a ₂ ) | + l / 2 ≦ L / 2
(Condition 2 ′) | (y ₁ + b ₁ ) − (y ₂ + b ₂ ) | + t / 2 ≦ T / 2
(Condition 3 ′) | (x ₁ + a ₁ ) − (x ₂ + a ₂ ) | + t / 2 ≦ T / 2
(Condition 4 ′) | (y ₁ + b ₁ ) − (y ₂ + b ₂ ) | + l / 2 ≦ L / 2
When the rotation shaft is biased in this way, it is preferable to use an adjustment member 215 that is not circular but has a crescent-shaped width w that is not constant (see, for example, FIG. 6).

In the first embodiment, the thickness t and the length l centered on the rotation axis of the knob 201 are the same in the left, right, top and bottom, and the width T and the length L about the rotation axis of the housing member 212 are the same. The explanation was made assuming that the left and right and up and down are equal. However, there may actually be a deviation of the rotation axis. In such a case, more accurate conditions can be obtained by correcting l / 2, t / 2, L / 2 and T / 2 in conditions 1 to 4. Specifically, the maximum value of the thickness from the rotation axis of the knob 201 is tmax, the larger value of the length from the rotation axis of the knob 201 is lmax, and the smaller value of the width of the housing member 212 from the rotation axis. And Tmin, and a small value of the length of the housing member 212 from the rotation axis is Lmin, the conditions 1 to 4 shown in the first embodiment are as follows.
(Condition 1 ") | x ₁ −x ₂ | + lmax ≦ Lmin
(Condition 2 ") | y ₁ −y ₂ | + tmax ≦ Tmin
(Condition 3 ") | x ₁ −x ₂ | + tmax ≦ Tmin
(Condition 4 ") | y ₁ −y ₂ | + lmax ≦ Lmin
The above two situations may occur at the same time, and the ideal conditions to be satisfied in this case will be apparent to those skilled in the art.

(Third embodiment)
FIG. 7 shows an unlocking assisting device according to the third embodiment of the present invention. The unlocking assisting device 700 is basically the same as the unlocking assisting device 210 described in the first embodiment, except that the expansion member 700 is attached to the housing member 212. In the present embodiment, for simplification, components other than the casing 214 and the housing member 212 are omitted in the drawing, the casing 214 is indicated by a dotted line, and the internal configuration is indicated by a solid line.

As shown in FIG. 8, the height of the thumb turn 200 from the contact surface 214 </ b> C of the housing 214 with the door is affected by the thickness of the door and may be different even in the same thumb turn 200. When the height h ₁ of the thumb turn 200 is smaller than the distance from the contact surface 214C to the surface 212B of the receiving member 212 facing the thumb turn 200, the receiving portion 212 cannot receive the knob 201 and can be rotated. Can not. In such a case, by attaching the expansion member 700 according to the present embodiment, the knob 201 can be accommodated and the unlocking operation can be appropriately performed.

However, if the height h ₂ of the thumb turn cylinder 202 is larger than the distance from the contact surface 214C to the surface 700A facing the thumb turn of the expansion member 700, the thumb turn cylinder 202 and the expansion member 700 come into contact with each other, and the casing 214 is a door. Will float from. Therefore, it is preferable to select the expansion member 700 having a height that accommodates the knob 201 and does not contact the thumb turn cylinder 202.

As shown in FIG. 9, even when the expansion member 700 is not used, if the height h ₁ of the thumb turn 200 is larger than the distance from the contact surface 214C to the bottom surface of the groove 212A of the housing member 212, the contact surface 214C door Will float from. In such a case, the gap between the door and the door can be filled by attaching the filling member 900 as shown in FIG. 9 to the contact surface 214C.

(Fourth embodiment)
If the housing member 212, the adjustment member 215, the expansion member 700, and the filling member 900 described in the first to third embodiments can be individually manufactured in accordance with the shape of the thumb turn 200 to which the unlocking assisting device 210 is attached. In practice, however, several types are manufactured in advance, assuming the types of major thumbturns 200 in the market and the height and arrangement of the general thumbturns 200 when installed on the door. The combination suitable for the thumb turn 200 to be attached is selected.

  At this time, in order to facilitate the attachment of the unlocking assisting device 210 and free the user from the burden of trial and error in alignment, it is preferable that the process of such selection is facilitated. Hereinafter, a set of attachment members such as the accommodation member 212, the adjustment member 215, the expansion member 700, and the filling member 900 is referred to as an “attachment set”.

  FIG. 10 shows a method for determining an attachment set suitable for the thumb turn to be attached.

  The user purchases the unlocking assisting device 210. When the unlocking assisting device 210 is purchased, the accessory member can also be received.

  Next, the user takes at least one of a front picture and a side picture of the thumb turn 200 to which the unlocking assisting device 210 is attached, and transmits it to a server operated by the seller (S1001). When taking a side picture, it is preferable to place the door in the shooting area as shown in FIG. Further, when taking a photograph, for example, as shown in FIG. 12, it is preferable to place a predetermined mark 1201 such as a coin around the thumb turn 200 and photograph it simultaneously (described later). Further, when taking a picture with a mobile terminal such as a smartphone, if a dedicated application is installed on the mobile terminal, the user's operation can be navigated using a UI that indicates the photo shooting position 1202.

The server that has received the photo analyzes the image and generates the shape information of the thumbturn 200 (S1002). The shape information obtained from the front photograph includes the thickness t and length l of the knob 201, the deviations a ₁ and b ₁ of the rotation axis of the knob 201 from the center position of the thumb turn cylinder 202, and the radius r or diameter of the thumb turn cylinder 202. At least one of 2r is included. The shape information obtained from the side photo, the height h ₂ of the heights h ₁ and thumb cylinder 202 of thumb turn 200 includes at least one of the manufacturer name 1101 and model number 1102. When the photograph includes a predetermined mark around the thumb turn 200, the mark can be used as a reference in calculating the size of the thumb turn shape by image analysis.

  The server holds an attachment set table that associates shape information with an attachment set suitable for the shape information, and refers to the table to determine an attachment set suitable for the thumb turn 200 to be attached (S1003). ). A plurality of attachment sets may be determined so that the user can select one of them. For example, an adjustment member 215 that minimizes the deviation between the rotation axis of the knob 201 and the rotation axis of the housing member 212 is included. An attachment set may be determined.

  The server transmits the contents of the determined attachment set to the user (S1004).

  The user selects a required member from the received attachment members based on the contents of the received attachment set, and fixes and attaches to the unlocking assisting device 210.

  As an alternative method, the attachment member is not sent to the user in advance, but the user first sends a picture of the thumb turn 200 to the server, determines a suitable attachment set, and then uses the unlocking assisting device 210. The attachment set determined to be may be delivered to the user.

  In particular, if the determined attachment set is attached to the unlocking assisting device 210 and then delivered to the user, the user can attach it simply by “sticking”. The attachment can be performed, for example, by peeling off the release paper of the double-sided tape that has been affixed to the contact surface 214C of the housing 214 and pressing it so as to cover the thumb turn.

If the manufacturer's name can be determined from the shape information, the accuracy may decrease, but even if other information cannot be analyzed, a suitable attachment set can be determined. If the model number is known, it can be determined with higher accuracy. If information about the heights h ₁ and h ₂ can be obtained, the accuracy can be increased. Even if there is no side photograph and only a front photograph, a certain degree of accuracy can be determined.

  The image analysis may include an initial diagnosis as to whether or not the photographed thumb turn 200 can be attached. For example, if the type of the lock is not compatible, a diagnosis result indicating that the lock cannot be attached may be transmitted to the user. In addition, an initial diagnosis table that associates the manufacturer name, model number, and the like with whether or not it can be attached is held in the server, and diagnosis can be performed with reference to the table.

  Also, instead of referring to the attachment set table, the optimum shape of each attachment is calculated from the shape information, and the attachment set that is close to or closest to the optimum shape is determined as the attachment set suitable for the thumb turn 200 to be attached. You may decide.

  Moreover, although the said operation demonstrated the example mainly performed in a server, it can also be performed in computers, such as a smart phone used by a user, a tablet, PC, a notebook PC. At this time, the photographed photo is not transmitted to the server but is read into an application operating on the computer. In any case, the computer can be caused to perform each operation by executing a program.

  In addition, when the generation of shape information by image analysis (S1002) fails, the user can be requested for measurement, and the attachment set can be determined (S1003) based on the received measurement result. At that time, if a dedicated application is installed in a mobile terminal such as a user's smartphone, a UI for instructing a measuring location can be used. In the case of taking a picture, if a dedicated application is installed in the mobile terminal, the user's operation can be navigated using a UI that indicates the picture taking position 1202.

  Also, users with psychological resistance to sending key photos are assumed. Safe data transmission / reception can be ensured by using an image editing function that deletes unnecessary reflections by automatically selecting a range other than the target after painting or by a user selecting a range. Alternatively, the user may check the initial diagnosis table information such as the manufacturer name and model number without uploading the photo.
