(Summary of the Invention)
The present invention makes it possible to use, as an electronic lock, a conventional lock that is locked and unlocked by a metal key by attaching an unlocking assisting device to a door provided with a lock having a thumb-turn. As a kind of key, although it can respond widely, there are some which can not respond.

  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 an 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 door. To be done. The unlocking signal can be transmitted by executing an application for transmitting the unlocking signal on the portable terminal 103 such as a smartphone, a tablet, a dedicated remote controller, or the like. For example, communication can be performed by Bluetooth such as Bluetooth (registered trademark) Low Energy (BLE), or ZigBee (registered trademark) (see FIG. 1). When ZigBee is used, the communication function by ZigBee is also required on the portable terminal 103. For example, at present, a smartphone can not be used as the portable terminal 103, and although the versatility is lowered, other small devices that can communicate are Not a few. Since the power consumption is low, energy saving of the unlocking assisting device can be achieved.

  The unlocking signal can be generated based on the unlocking authority as to which unlocking assist device can be driven, which is recorded in each portable terminal. The unlocking authority that can be recorded in each mobile terminal can be managed by the management server with which each mobile terminal can communicate. For example, date and time, time zone restrictions, frequency restrictions, etc. can be imposed. Alternatively, the unlocking authority can be given to a specific friend on the SNS. From the viewpoint of security, the unlocking signal can be a mechanism that does not unlock even if the unlocking signal is intercepted and the same signal is reproduced.

  In addition, the unlocking assisting device 102 can be provided with a sensor that detects the 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 detects an object, which facilitates unlocking when moving from indoor to outdoor. . A display unit such as a touch panel display can be provided in a housing of the unlocking assist device 102, and the display unit can be used as a pressure sensor. In addition, it is also possible to use a tactile switch or the like that changes in capacitance when an object comes in contact or approaches, or that is turned on / off by pressing.

  Actually, when trying to attach such an unlocking assisting device, there are cases where the unlocking assisting device and the thumbturn do not mesh well due to the existence of various types of thumbturns. In the present invention, by disposing the adjusting member at least at a part of the periphery of the thumb-turn cylinder, the attachment error between the thumb-turn and the unlocking-assisting device can be suppressed. Promote the spread of tablets greatly.

First Embodiment
FIG. 2A shows a back view of the unlocking assisting device according to an embodiment of the present invention, and FIG. 2B shows a cross-sectional view thereof taken along the line B-B. In FIG. 2B, a thumb turn 200 having a knob 201 and a thumb turn barrel 202 is also shown. The unlocking assisting device 210 is an assisting device of a lock having the thumb turn 200, and a recess 211 covering the thumb turn 200, a receiving member 212 for receiving the knob 201 of the thumb turn 200 in the recess 211, and a drive for rotating the receiving member 212. And a unit 213.

  Although the concave portion 211 is illustrated as having a circular shape in the rear view, it is also necessary to change the shape according to the type of lock to be attached, and the shape of the concave portion 211 according to the present embodiment is appropriately appropriate. It 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 the other portions generally corresponds to the recess 211.

  The housing member 212 can be positioned by the projection 214A of the housing 214 of the unlocking assisting device 210 and can be disposed to be the bottom of the recess 211. Although the width T of the groove 212A for housing the knob 201 is wider than the thickness of the knob 201, if the gap with the knob 201 in the groove 212A is large, the accuracy of the angle detection of the knob is lowered. It is desirable to make it smaller. Further, in order to cope with a crime prevention thumb turn of a type in which the button is pressed while being pressed, if the gap is large and the amount of pressing the button is shallow, it can not be unlocked. It is appropriate to control the distance between the and the knobs 201 with an accuracy of ± 0.2 mm. As shown in FIG. 2C, the housing member 212 may be disposed closer to the thumb-turn 200 than the protrusion 214A. At this time, the shape of the housing 214 can be designed as appropriate including the protrusion 214A.

  The drive 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 adjusting member 215 for reducing the gap D between the thumb-turn cylinder 201 and the side surface 214 B of the recess 211. By arranging the adjusting member 215 at least at a part of the periphery of the thumb-turn cylinder 202, the shift between the thumb-turn 200 and the unlocking assisting device 210 can be suppressed, so that the unlocking assisting device 210 can be easily attached to the door. Will be able to As shown in FIG. 2D, the adjustment member 215 may be fixed not at the side surface 214B of the recess 211, or together with the side surface 214B at another part of the housing 214 such as the protrusion 214A.

  In order for the housing member 212 to accommodate the knob 201 and perform the necessary rotation for unlocking, positioning in the order of mm is often required, and the user of the attachment of the unlocking assist device 210 is required. There is a risk of forcing excessive trial and error. According to the present embodiment, by providing the adjustment member 215 for appropriately arranging the thumb-turn 200, the mounting error can be suppressed, and the user can be mounted even if his eyes are closed.

FIG. 3A shows the arrangement of the groove of the housing member and the thumb turn knob according to the present embodiment. The groove 212A is indicated by a dotted line. Here, it is assumed that the rotation axis of the knob 201 is positioned at the center of the thumb turn barrel 202. Further, consider the case where the rotation axis of the housing member 212 is positioned at the center of the groove 212A. The coordinates of the center position of the thumb-turn cylinder _{202 (x 1, y 1)} , the coordinates of the center position of the groove 212A and (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 is rotated 90 degrees in the arrangement relationship shown in FIG. 3A. In order that the knob 201 can be unlocked by being rotated 90 degrees, it can be seen from the figure that | x ₁ −x ₂ | + l / 2 needs to be L / 2 or less (condition 1) . Similarly, it is necessary that | y ₁ −y ₂ | + t / 2 be equal to or less than T / 2 (condition 2). Further, as a premise, since the knob 201 must be able to be accommodated in the groove portion 212A, it is required that | x ₁ −x ₂ | + t / 2 is equal to or less than T / 2 (condition 3), | y ₁ −y ₂ | + l / l It is necessary that 2 be L / 2 or less (condition 4). It is as follows when arranging it.
(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 a circle having a radius R, as shown in FIG. 4A, the radius of the thumb turn cylinder is r, and the maximum values of Δx (= x ₁ −x ₂ ) and Δy (= y ₁ −y ₂ ) Becomes R-r. In FIG. 4A, the side surface 214B of the recess 211 is also shown by a dotted line. In the illustrated example, the displacement of the knob 201 is large, and the knob 201 can not be accommodated in the groove portion 212A. Naturally, the knob 201 can not be rotated. Condition 3 above 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 y-axis direction are w ₁ and w ₂ as the maximum value of the deviation Δx and Δy between the rotation axis of the rotary shaft and the housing member 212 of the knob 201 is limited to R-r-w ₁ and R-r-w _2. By appropriately designing the widths w ₁ and w ₂ , the conditions 1 to 4 can be satisfied. If the above conditions are rewritten, w ₁ and w ₂ may be designed to satisfy the following equation.

| 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 a concrete example. Assuming that the thickness t of the knob 201 is 2 mm and the width T of the groove 212A is 6 mm, for example,
| Y ₁ −y ₂ | + t / 2 ≦ T / 2,
That is,
| Y ₁ −y ₂ | ≦ T / 2−t / 2 = 2 mm
In order to satisfy the condition of (1), it is necessary to mount in the y direction (vertical direction). Within such tolerances it is extremely difficult for the user to manually and correctly attach, and if it is not attached well, the rotational movement will stop prematurely, an undue load on the lock or unlocking aid It brings about such a defect.

Since such mounting accuracy is required, the housing 214 and the adjustment member 212 must be partially transparent to provide a window for confirmation, or an opening must be provided to enable visual attachment. Although there is a possibility, by providing the adjusting member 215 according to the present embodiment, if the user puts the thumb-turn 200 in the recess 211 of the unlocking assisting device 210, only a slight positional adjustment, if necessary, is possible. The installation can be completed. For example, in the present embodiment, the mounting can be facilitated even if the housing member 212 is disposed in the housing 214 so as not to be visible in the front view and / or the side view of the unlocking assisting device 210. Also, even if the housing 214, the adjustment member 215, etc. are opaque, the user can easily attach. Preferably, the adjusting member 215 is entirely disposed within the housing 214 at least in a front view of the unlocking assisting device 210.

  In FIGS. 4A and 4B, the adjusting member 215 is illustrated as having an annular shape, but it is not necessary to be constant as long as the conditions 1 to 4 can be satisfied, and it is not necessary to be constant. The shape of can be adopted. In the case of protrusions, for example, three protrusions may be arranged at substantially equal intervals along the side surface 214B of the recess 211 (see FIG. 4C). In addition, although the description is made on the premise that the knob 201 is vertically locked and horizontally unlocked, the unlocking assisting device 210 of the present embodiment can be naturally applied to a lock whose reverse aspect is reversed.

  Moreover, as shown to FIG. 5A, the case where one 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 non-released side surfaces is A (2R in the case of a circular arc), the maximum value of the displacement of the knob 201 in that direction is A / 2-r. By providing the adjustment member 500 as shown in FIG. 5B, the maximum value of the deviation can be limited in at least one direction. It is possible for the user to install the unlocking assist device 210 by merely attaching the adjusting member 500 in the direction in which the adjusting member 500 is disposed, and slightly aligning the direction in which the side face orthogonal to the adjusting member 500 is partially closed Become. The shape of the adjustment member 500 is not limited to the one as illustrated in FIG. 5B, and as described above, shapes such as an annular shape, a crescent shape, a protrusion shape, and a rectangular shape can be used.

  Ideally, if the shape of the recess 211 can be changed such that the shape of the thumbturn 200 to be attached can satisfy the above conditions 1 to 4 by appropriately selecting the adjusting member 215, the user turns the thumbturn 200 into the recess 211. Alignment is completed only by installing so as to be in.

  In actual manufacture, the gap D between the thumb-turn cylinder 201 and the side surface 214B of the recess 211 is at least at least at the side surface 214B due to the presence of the adjusting member 215 even if all of the above conditions 1 to 4 are not necessarily strictly satisfied. Such adjustment member 215 is also within the technical scope of the present embodiment, since the trial and error at the time of installation of the user can be greatly reduced if reduction is possible even in part.

  Although the above description has been made on the premise that the thumb turn barrel 202 is a circular lock, it is not necessarily limited to this.

  2B and the like, the adjusting member 215 is described as reducing the gap D between the thumb-turn cylinder 201 and the side surface 214B of the recess 211. However, depending on the shape of the housing 214, the side surface 214B is clearly identified. Sometimes things are difficult. Even in such a case, the shape of the recess 211 is changed using the adjustment member 215 to suppress the deviation between the rotation axis of the knob 201 and the rotation axis of the housing member 212, thereby attaching the unlocking assist device 210. The same can be done easily.

Second Embodiment
In the first embodiment, the rotation axis of the knob 201 is positioned at the center of the thumb turn barrel 202, and the rotation axis of the housing member 212 is positioned at the center of the groove 212A. Alternatively, the rotation axis of the knob 201 may be at coordinates (x ₁ + a ₁ , y ₁ + b ₁ ), and the rotation axis of the housing member may be at coordinates (x ₂ + a ₂ , y ₂ + b ₂ ). At this time, 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
As described above, in the case where the rotational axis is biased, it is preferable to use an adjusting member 215 that is not annular but has a width w such as crescent shape that is not constant (see, for example, FIG. 6).

Further, in the first embodiment, the thickness t and the length l centering on the rotation axis of the knob 201 are equal in the left and right and up and down, and the width T and the length L centering on the rotation axis of the housing member 212 It was explained assuming that the left, right, top and bottom are equal. However, there may be an actual 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 under conditions 1 to 4. Specifically, a large value of the thickness from the rotation axis of the knob 201 is tmax, a large value of the length from the rotation axis of the knob 201 is lmax, and a small value of the width from the rotation axis of the housing member 212 Assuming that Tmin and the small value of the length from the rotation axis of the housing member 212 is Lmin, 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 T Tmin
(Condition 4 ′ ′) | y ₁ −y ₂ | + lmax ≦ Lmin
The above two situations may occur simultaneously, and the ideal conditions to be satisfied at that time will be apparent to those skilled in the art.

Third Embodiment
FIG. 7 shows an unlocking assist device according to a 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, but differs in that the expansion member 700 is attached to the housing member 212. In the present embodiment, for simplification, components other than the housing 214 and the housing member 212 are omitted in the drawing, and the housing 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 C with the door of the housing 214 may be different even with the same thumb turn 200 due to the influence of the thickness of the door and the like. The height h ₁ of the thumb 200 and smaller than the distance to the surface 212B opposite to the thumb turn 200 of the housing member 212 from the contact surface 214C, housing portion 212 is not able to accommodate the knob 201, to be rotated Can not. In such a case, by attaching the extension member 700 according to the present embodiment, the knob 201 can be accommodated and the unlocking operation can be appropriately performed.

However, the height h ₂ of the thumb-turn cylinder 202 and greater than the distance from the contact surface 214C until the surface 700A facing the thumb turn of expansion member 700, extension member 700 is in contact with the thumb turn cylinder 202, the housing 214 is door It floats away. Therefore, it is preferable to select the expansion member 700 which accommodates the knob 201 and does not contact the thumb-turn cylinder 202.

As shown in FIG. 9, in the case of not using the extension member 700 is also the height h ₁ of the thumb 200 and larger than the distance from the contact surface 214C to the bottom surface of the groove portion 212A of the housing member 212, the contact surface 214C door It floats away. 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
The accommodating member 212, the adjusting member 215, the expanding member 700 and the filling member 900 described in the first to third embodiments can be individually manufactured according to the shape of the thumb turn 200 to which the unlocking assisting device 210 is attached. Although it is good, in reality, several types are manufactured in advance, supposing the types of major Samturn 200 distributed in the market and the height / arrangement of general Samturn 200 when installed on the door. , And a combination suitable for the thumbturn 200 to be attached.

  At this time, in order to facilitate the attachment of the unlocking assist device 210 and to relieve the user from the burden of trial and error of alignment, it is preferable that the process of such selection is also facilitated. Hereinafter, a combination of one set of attachment members such as the housing 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 of determining an attachment set suitable for the thumb turn to be attached.

  The user purchases the unlocking assist device 210. When purchasing the unlocking aid 210, accessories can also be received.

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

The server that has received the picture analyzes the image and generates shape information of the thumb turn 200 (S1002). The shape information obtained from the front photo, the thickness t and length l of the knob 201, shift a ₁ and b ₁ from the center position of the thumb turn cylinder 202 of the rotary shaft of the knob 201, the radius r or the 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 predetermined marks around the thumb turn 200, the mark can be used as a reference in calculating the dimensions of the shape of the thumb turn from image analysis.

  The server holds an attachment set table that associates shape information with a suitable attachment set, and refers to the table to determine an attachment set suitable for the thumbturn 200 to be attached (S1003). ). A plurality of attachment sets may be determined to allow the user to select one, for example, including 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. The attachment set may be determined.

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

  Based on the content of the received attachment set, the user selects a required member from the received accessories, fixes it to the unlocking assist device 210, and performs attachment.

As an alternative method, instead of sending the attachment to the user beforehand, the user is first required to send a picture of the thumb turn 200 to the server, and a suitable attachment set is determined. May be delivered to the user.

  In particular, if the determined attachment set is attached to the unlocking assisting device 210 and delivered to the user, the user can attach it by "pasting only". The attachment can be performed, for example, by peeling off the release paper of the double-sided tape previously attached to the contact surface 214C of the housing 214 and pressing it so as to cover the thumb turn.

If the manufacturer's name is known from the shape information, the accuracy may decrease, but it is possible to determine a suitable attachment set even if other information can not be analyzed. Once the model number is known, it can be determined with higher accuracy. If information about the heights h ₁ and h ₂ is obtained, the accuracy can be enhanced. Even if there is no side view and only a front view, it is possible to determine a certain accuracy.

  Note that the image analysis may include an initial diagnosis of whether or not the photographed thumbturn 200 can be attached. For example, if the type of lock is not compatible, the non-attachable diagnosis result may be transmitted to the user. In addition, an initial diagnosis table that associates maker name, model number, etc. with attachment possibility or not may be held in the server, and diagnosis may be performed with reference to the table.

  Also, the optimum shape of each attachment is calculated from the shape information, not referring to the attachment set table, and the attachment set close to or closest to the optimum shape is used as an attachment set suitable for the thumbturn 200 to be attached. You may decide.

  In addition, although the above-described operation has been mainly described in the example performed in the server, it may be performed in a computer such as a smartphone, a tablet, a PC, or a laptop PC used by the user. At this time, the photographed picture is not transmitted to the server but read into an application operating on a computer. In any case, the computer can perform each operation by executing the program.

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

  Also, it is assumed that users who have psychological resistance in sending key photos. Safe data transmission and reception can be secured by using the image editing function of deleting unnecessary reflected parts by automatically selecting or filling in a range other than the target part after photographing a picture. In addition, the user may check initial diagnosis table information such as a maker name and a model number without uploading a photo.
