Description

Technology Field

[0001] The present invention relates to an anti-theft system capable of adjusting the angle of a mirror to check blind spots, and more specifically, to an anti-theft system capable of adjusting the angle of a mirror to check blind spots that are not visible due to goods or customers in places where a single person manages the store, such as a convenience store. Background Technology

[0002] Generally, in the case of 24-hour convenience stores, the number of customers decreases sharply during late-night hours (e.g., 23:00 to 7:00), and as a result, it frequently happens that employee labor costs exceed sales profits during that time.

[0003] In addition, there is a concern that various criminal incidents threatening employee safety may occur during late-night hours.

[0004] In the case of convenience stores, since a single employee is stationed to manage the entire store, attention is inevitably dispersed when many customers are present, leading to the problem that it is difficult to prevent or detect theft.

[0005] Such theft incidents can frequently occur at display shelves located in blind spots, and to prevent such incidents, the store interior is equipped with reflective mirrors that illuminate these areas, allowing employees to check the shelves in those blind spots.

[0006] Reflective mirrors have the advantage of allowing employees to check shelves in blind spots from their position at the sales counter, but there was a problem in that additional blind spots could occur due to the employee's physique or the location of the items.

[0007] In particular, since most mirrors are fixed to the wall, it is impossible to adjust them to fit the physique of the employees working in shifts, making it difficult to check display shelves in blind spots from the sales counter.

[0008] In addition, most convenience stores are equipped with CCTVs to monitor the interior; however, this video surveillance method is used to verify theft after it has occurred, and there was a problem in that if the theft went unnoticed, it was attributed to a calculation error by the staff.

Prior to this, if it is determined that a detailed description of the functions and configurations related to the present invention may unnecessarily obscure the essence of the invention, such detailed description will be omitted.

[0022] The present invention relates to an anti-theft system capable of adjusting the angle of a mirror to check blind spots, and more specifically, to an anti-theft system capable of adjusting the angle of a mirror to check blind spots that are not visible due to goods or customers in places where a single person manages the store, such as a convenience store.

It is characterized by including a control motor (600) that is coupled to the control unit (300) to control the rotation angle, and a control unit (700) formed on the rear surface of the reflector (100) and formed to receive a control signal via wireless communication to remotely control the operation of the rotation motor (500) and the control motor (600).

[0027] The reflector (100) is composed of a mirror formed to reflect the shape of an object using light reflection on the front surface, and a connecting member (110) is provided in the center of the rear surface so that it can be connected to a pivot member (200).

[0028] Since the reflector (100) is used to check display shelves that are not visible from the sales counter where staff are stationed, it is desirable that the front surface be formed as a convex mirror so as to have a wide field of view.

[0029] In addition, depending on the size of the store, multiple reflectors (100) may be formed on the interior walls of the store at regular intervals so that each display shelf can be checked by an employee from the sales counter.

[0030] The pivot member (200) is connected to the rear of the reflector (100) and is used to allow the angle of the reflector (100) to be adjusted in a vertical direction, and the front is open so that a fastening member (110) formed in the center of the rear of the reflector (100) can be inserted inside.

[0031] At this time, a hole is provided on the outer surface of the pivot member (200) so that a screw can be inserted, and the pivot member (200) can be fixed to the rear surface of the reflector (100) by the screw pressing against the outer surface of the pivot member (110).

[0032] In addition, the rear center of the pivoting member (200) is provided with a pivoting member (210) that protrudes outwardly and is formed to be inserted into the front of the adjustment member (300), and the pivoting member (210) is provided with a hole that penetrates in the horizontal direction.

[0033] At this time, the rotation shaft (510) of the rotation motor (500) is inserted horizontally into a hole provided in the rotation section (210) and can be secured by a key connection, and the rotation stand (200) rotates vertically according to the rotation direction of the rotation motor (500), thereby allowing the reflector (100) attached to the front of the rotation stand (200) to move up and down.

[0034] The adjustment rod (300) is used to support the rotational section (210) so that it can rotate in a vertical direction, and to rotate in a horizontal direction by the adjustment motor (600).

[0035] To this end, a pair of connecting ends (310) protruding outwardly are provided on one side and the other side of the front of the adjustment member (300), and a rotating end (210) formed on the rotating member (200) is formed so that it can be inserted between the connecting ends (310).

[0036] At this time, the connecting portion (310) is formed with a hole penetrating in the horizontal direction so that the rotation shaft (510) of the rotation motor (500) can be inserted, and it is preferable that a bearing be formed inside the hole so that the rotation shaft (510) can rotate freely without the connecting portion (310) being connected to the rotation shaft (510).

[0037] It is preferable that the connecting member (310) and the rotating member (210) be formed such that their central axes coincide so that the rotating shaft (510) can be inserted, and it is preferable that the rotating member (210) and the connecting member (310) be formed vertically so that the rotating member (200) can rotate in a vertical direction.

[0038] In addition, the rear center of the adjustment member (300) is provided with an adjustment member (320) that protrudes outwardly and is formed to be inserted into the front of the fixing member (400), and the adjustment member (320) is provided with a hole that penetrates in the vertical direction.

[0039] At this time, the adjustment shaft (610) of the adjustment motor (600) is inserted vertically into a hole provided in the adjustment section (320) and can be secured by a key connection, and the adjustment rod (300) rotates horizontally according to the rotation direction of the adjustment motor (600), thereby allowing the rotation rod (200) and the reflector (100) connected to the front of the adjustment rod (300) to move left and right.

[0040] The fixing member (400) supports the adjustment member (320) connected to the front so that it can rotate in a horizontal direction, and the rear is formed with a bracket (not shown) so that it can be connected to the wall inside the store.

[0041] In order to allow the adjustment member (320) to be connected, a pair of fixing members (410) protruding outwardly are provided on the upper and lower front surfaces of the fixing member (400), and the adjustment member (320) formed on the adjustment member (300) is formed to be inserted between the fixing members (410).

[0042] At this time, the fixed end (410) is formed with a hole penetrating in the vertical direction so that the control shaft (610) of the control motor (600) can be inserted, and it is preferable that a bearing be formed inside the hole so that the control shaft (610) can rotate freely without the fixed end (410) being connected to the control shaft (610).

[0043] It is preferable that the adjustment section (320) and the fixed section (410) be formed such that their central axes align so that the adjustment shaft (610) can be inserted, and it is preferable that the adjustment section (320) and the fixed section (410) be formed horizontally so that the adjustment rod (300) can rotate in a horizontal direction.

[0044] In addition, it is preferable that one side and the other side of the rear of the pivoting member (200) have arc-shaped grooves formed therein to prevent interference with vertical rotation when the connecting member (310) is joined.

[0045] In addition, it is preferable that the upper and lower rear portions of the adjustment member (300) have arc-shaped grooves formed therein to prevent interference with horizontal rotation when the fixed portion (410) is connected.

[0046] Through this, the rotating member (200), the adjusting member (300), and the fixing member (400) can be formed with a short length while connected to each other, and the length of the connection between the components can be reduced, thereby reducing the moment caused by the weight of the reflector (100).

[0047] The rotation motor (500) is formed to be supported by a fixed bracket (520) coupled to one side of the adjustment rod (300), and the rotation shaft (510) formed in the rotation motor (500) passes through the connecting end (310) and the rotation end (210), and is connected to the rotation end (210) by a key and connected to the connecting end (310) so as to be freely rotatable by means of a bearing.

[0048] Additionally, the rotation motor (500) is controlled by the control unit (700) to rotate the rotation axis (510) clockwise or counterclockwise, and as the key-coupled rotational end (210) rotates along the rotational direction of the rotational axis (510), the front surface of the rotational stand (200) coupled with the reflector (100) can be rotated vertically.

[0049] The control motor (600) is formed to be supported by a support bracket (620) coupled to the lower part of the fixing base (400), and the control shaft (610) formed in the control motor (600) passes through the fixing end (410) and the control end (320), and is connected to the control end (320) by a key and connected to the connecting end (310) so as to be freely rotatable by a bearing.

[0050] Additionally, the control motor (600) is controlled by the control unit (700) to rotate the control shaft (610) clockwise or counterclockwise, and as the key-coupled control unit (320) rotates along the rotation direction of the control shaft (610), the front of the control unit (300) coupled with the pivot unit (200) can rotate horizontally.

[0051] The rotation motor (500) and the support motor are formed to determine the number of rotations using a stepper motor, and through this, the current angle of the reflector (100) can be determined and controlled to return to the initial position.

[0052] The control unit (700) can be formed on the rear or wall surface of the reflector (100) and can be operated by supplying external power and applying power and control signals to the rotation motor (500) and the adjustment motor (600), thereby allowing the angle of the reflector (100) to be adjusted.

[0053] At this time, the control unit (700) can receive a control signal generated by an employee located at the sales counter using wireless communication, and can adjust the position of the reflector (100) by operating the rotation motor (500) and the adjustment motor (600) in accordance with the received control signal.

[0054] FIG. 3 is a perspective view showing the angle of a theft prevention system that can adjust the angle of a reflector (100) to check blind spots according to the present invention, and FIG. 4 is a configuration diagram showing the overall configuration of a theft prevention system that can adjust the angle of a reflector (100) to check blind spots according to the present invention.

[0055] As illustrated in FIGS. 3 and 4, the anti-theft system according to the present invention, which allows for angle adjustment of the reflector (100) to check blind spots, further includes a monitoring unit (800) formed on a sales stand to remotely control the operation of the control unit (700) and check the operation status, and the monitoring unit consists of a display (810) formed to visually check the setting status and operation status of the control unit (700), and a controller (820) formed to manually operate the rotation motor (500) and the adjustment motor (600).

[0056] The display (810) is used to remotely check the status of the control unit (700), rotation motor (500), and adjustment motor (600) installed on the wall, and to check data regarding the initial position of the reflector (100) set according to the employee's physique.

[0057] At this time, it is preferable that the display (810) be formed as a touchscreen so that the setting state can be changed.

[0058] The controller (820) can be formed as a joystick to adjust the angle of the mirror (100), and the rotation motor (500) and the adjustment motor (600) are operated in accordance with the movement of the joystick so that the angle of the mirror (100) can be adjusted remotely.

[0059] Additionally, as needed, the monitoring unit (800) may be controlled using a terminal (830) consisting of a smartphone or tablet PC carried by an employee, and when using the terminal (830), the control unit (700) can be set and the operating status checked through the display (810), and the rotation motor (500) and the adjustment motor (600) can be controlled through the touchscreen.

[0060] In addition, when using the terminal (830), when organizing items while moving around inside the store rather than at the sales counter, the angle of the reflector (100) can be adjusted based on the position of the employee to check for blind spots.

[0061] It is preferable that the control unit (700) has a communication module (710) built in so that it can receive a control signal from the monitoring unit (800) via wireless communication, and the communication module (710) can use Bluetooth, Wi-Fi, or LTE.

[0062] In addition, the control unit (700) is characterized by storing the rotational speeds of the rotation motor (500) and the adjustment motor (600) to independently set the position of the reflector (100) according to the body size, and automatically returning the reflector (100), whose angle has been adjusted by a control signal, to the set position.

[0063] Generally, since employees working at convenience stores work in shifts, it is necessary for the angle of the reflector (100) to be automatically adjusted so that the display shelves in the blind spot can be checked according to each employee's body size.

[0064] To this end, the control unit (700) is configured to simultaneously control the angle of the reflector (100) in two axes using a rotation motor (500) and a control motor (600), and has a built-in memory so that the initial position of the reflector (100) can be independently set according to the physique of the employee working in the store.

[0065] The rotation motor (500) and the control motor (600) are composed of step motors so that the number of rotations can be checked, and the control unit (700) can determine the initial position and current position of the rotation motor (500) and the control motor (600) and control the operation of the rotation motor (500) and the control motor (600) so that the reflector (100) is positioned at an angle stored in memory.

[0066] The employee can adjust the angle of the reflector (100) that is clearly visible in the blind spot through the controller (820) or terminal (830) while sitting or standing at the sales counter, and the number of rotations of the rotation motor (500) and the adjustment motor (600) operated to adjust the angle can be stored in the memory formed in the control unit (700).

[0067] At this time, the name of each employee can be stored together in memory, and when the name of an employee is selected through the display (810), the rotation motor (500) and the adjustment motor (600) rotate according to the number of rotations set in the memory, so that the reflector (100) can be automatically changed to a set position.

[0068] This allows the angle of the reflector (100) to be automatically restored to the set value stored in memory without the need to manually adjust it when employees take turns working.

[0069] Additionally, the control unit (700) further includes a recognition sensor (720) formed at the edge of the mirror (100) to capture a customer approaching a display stand in a blind spot, and is characterized by being able to automatically adjust the angle of the mirror (100) according to the position of the customer detected through the recognition sensor (720).

[0070] The recognition sensor (720) is used to analyze the movement of a customer moving within the range of the blind spot display when the customer approaches the blind spot display, and a camera can be used.

[0071] The recognition sensor (720) can control the mirror (100) to track customers moving along the aisle of the display stand while capturing a customer who has entered the direction of the display stand in the blind spot from the outer surface of the mirror (100).

[0072] Through this, the control unit (700) can control the rotational speed of the rotation motor (500) and the adjustment motor (600) so that the reflector (100) moves along with the customer detected by the recognition sensor (720), and when the customer moves out of the blind spot, it can be restored to the initial angle set by the employee.

[0073] The control unit (700) further includes a LiDAR sensor (730) for automatically determining the position, height, and distance between the sales stand and the display stand in the blind spot, and is characterized by calculating the angle between the sales stand and the display stand in the blind spot through the LiDAR sensor (730) and automatically adjusting the angle of the reflector (100).

[0074] The LiDAR sensor (730) is formed on the outer edge of the reflector (100) so that the reflector (100) can collect information about objects and people around the display stand and the blind spot based on the set angle.

[0075] At this time, the LiDAR sensor (730) automatically and actively adjusts the angle of the reflector (100) based on the reflector (100) when an obstacle that can obstruct the view occurs around the sales counter and the display stand in the blind spot, so that the employee located at the sales counter can check the display stand in the blind spot in real time.

[0076] At this time, the LiDAR sensor (730) can form a map view of the location, height, and distance of the display stand in the blind spot using cloud points, and an employee at the sales counter can check the display stand in the blind spot through the reflector (100) without obstruction of view by obstacles.

[0077] In addition, the LiDAR sensor (730) can recognize an employee located at the sales counter, and when the employee moves to the display counter for store management, the LiDAR sensor (730) can continuously track the employee and adjust the angle of the reflector (100) so that the blind spot of the display counter can be checked from the employee's current location.

[0078] That is, the angle at which the reflector (100) can illuminate the display stand in the blind spot can be calculated based on the employee's current location, and based on this, the display stand in the blind spot can be checked through the reflector (100) regardless of the location where the employee moves.

[0079] As described above, according to the anti-theft system of the present invention, which allows for angle adjustment of a mirror to check blind spots, the angle of the mirror can be varied according to the employee's physique, thereby allowing the display stand located in a blind spot to be checked from the sales counter, thus preventing theft. Additionally, since the angle of the mirror can be remotely adjusted from the sales counter, additional blind spots that cannot be checked from a specific angle can be checked. Furthermore, when a customer enters a display stand in a blind spot, the angle of the mirror changes to follow the customer, thereby enabling the employee at the sales counter to check the customer's location in real time.

[0080] As described above, although the present invention has been explained with reference to preferred embodiments, those skilled in the art may implement the present invention with various modifications or variations without departing from the technical spirit and scope described in the claims of the present invention. Accordingly, the scope of the present invention should be interpreted by the claims described to include such many variations. Explanation of the symbols
