Modes for Carrying Out the Invention

[0009] 〔Embodiment 1〕 Hereinafter, an embodiment of the present invention will be described. Note that the following description is an example of the chair with an electronic tag according to the present invention, and the technical scope of the present invention is not limited to the illustrated examples.

[0010] [Configuration Example of Chair 1 with Electronic Tag] First, with reference to FIGS. 1 and 2, a configuration example of the chair 1 with an electronic tag according to this embodiment will be described. FIG. 1 is a view showing the appearance of the chair 1 with an electronic tag according to this embodiment. 1001 in FIG. 1 is a front perspective view, and 1002 in FIG. 1 is a rear perspective view. FIG. 2 is a plan view showing a schematic configuration of the electronic tag 4 provided in the chair 1 with an electronic tag.

[0011] The chair 1 with an electronic tag according to this embodiment is a swivel chair used, for example, in an office or a conference room. As shown in FIG. 1, the chair 1 with an electronic tag includes a chair body 2 and an electronic tag 4 provided on the chair body 2.

[0012] As main members, the chair body 2 includes a seat 21, a backrest 22, a back frame 23 to which the backrest 22 is attached, and legs 24. Further, the chair body 2 may include, for example, as optional items, armrests 25 and a headrest 26.

[0013] The chair body 2 has a rocking function in which the backrest 22 can recline. Thereby, the seated person can relax the body and sit on the chair 1 with an electronic tag, and can continue to use it for a long time.

[0014] In the illustrated example, the legs 24 are, for example, of a five-leg type branched into five, and casters 27 are attached to the lower end of each of the five legs. The caster 27 is, for example, a swivel type caster that can rotate horizontally. Thereby, the chair 1 with an electronic tag can be easily moved.

[0015] In this embodiment, the electronic tag 4 is provided on the back surface of the backrest 22 of the chair body 2. Unique identification information (for example, an identification number such as a manufacturing number (serial number)) for identifying the chair body 2 is assigned to the electronic tag 4. The chair body 2 can be uniquely specified by this identification information. The identification information may be written into the electronic tag 4 using a writing device (writer) at the time of manufacturing or packing the chair 1 with an electronic tag, for example.

[0016] The electronic tag 4 is, for example, a passive type RFID (Radio Frequency Identification) tag that does not incorporate a battery. By using a passive type RFID tag that does not have a battery (power source) for holding and transmitting identification information as the electronic tag 4, it is possible to miniaturize and reduce the cost of the electronic tag 4 compared to an active type RFID tag that has a battery.

[0017] However, an active type RFID tag may be used as the electronic tag 4. Also, instead of the RFID tag, other wireless tags such as BLE (Bluetooth (Registered Trademark) Low Energy) tags may be used.

[0018] As shown in FIG. 2, the electronic tag 4 includes an IC chip 41 having a memory area (storage unit) 41A for storing the identification information of the chair body 2, and an IC antenna (antenna) 32 capable of wireless communication with a reading device 5 (see FIG. 3). The IC chip 41 and the IC antenna 42 are provided on a base material 33.

[0019] The IC chip 41 is, for example, a semiconductor chip and is disposed at the center of the base material 33. The IC chip 41 is equipped with a simple microcomputer, EEPROM (Registered Trademark), RAM, etc., and has a memory area 41A as a medium for storing identification information.

[0020] The IC antenna 42 is disposed so as to spiral around the IC chip 41. When the IC antenna 42 receives the radio wave transmitted from the reading device 5, a current flows through the IC antenna 42 due to the resonance effect. An electromotive force for operating the IC chip 41 is generated by this current. When the IC chip 41 operates, the identification information stored in the memory area 41A is encoded by the IC chip 41, and the encoded data is wirelessly transmitted to the reading device 5 via the IC antenna 42.

[0021] Note that the electronic tag 4 may be provided on the backrest 22, legs 24, armrests 25, etc. instead of the seat 21 of the chair body 2. Even in this case, the identification information stored in the electronic tag 4 can be easily acquired by reading the identification information with the reading device 5.

[0022] [Configuration example of chair management system 100] Next, a configuration example of a chair management system including the above-described chair 1 with an electronic tag will be described. FIG. 3 is a block diagram showing a configuration example of the chair management system 100. As shown in FIG. 3, the chair management system 100 includes a chair 1 with an electronic tag, a reading device 5, a communication terminal 6, a server (processing device) 7, and a database 8.

[0023] The reading device 5 is used to read the identification information from the electronic tag 4. In the present embodiment, the reading device 5 is, for example, a portable handheld reader. The reading device 5 includes a reading unit 51 that irradiates the electronic tag 4 with radio waves to read the identification information. The reading device 5 irradiates the electronic tag 4 with radio waves while being held by the user, and transmits the read identification information to the communication terminal 6 by wire or wirelessly.

[0024] The communication terminal 6 is used to acquire the identification information read by the reading device 5 and transmit and receive various information to and from the server 7. The communication terminal 6 is, for example, a portable communication device such as a smartphone. The communication terminal 6 includes a display unit (display) 61. The communication terminal 6 transmits the identification information read by the reading device 5 to the server 7 through a network line. Further, the communication terminal 6 acquires the product information of the chair 1 with an electronic tag associated with the identification information from the server 7 through a network line, and displays the product information on the display unit 61.

[0025] Server 7 performs management processing of the chair 1 with an electronic tag based on the identification information acquired from the communication terminal 6. Server 7 is, for example, a server computer installed on the cloud. Server 7 includes a control unit 71 such as a CPU that controls the management processing of the chair 1 with an electronic tag. When Server 7 acquires identification information from the communication terminal 6, for example, it reads out the product information of the chair 1 with an electronic tag associated with the identification information from the database 8. Then, Server 7 transmits the read product information to the communication terminal 6 through the network line.

[0026] Database 8 stores the product information of the chair 1 with an electronic tag. Table 1 shows an example of the product information stored in database 8.

Table 1

[0027] As shown in Table 1, the product information includes various information regarding the chair 1 with an electronic tag. In the example of Table 1, the product information includes, as information of the chair 1 with an electronic tag associated with the identification information (serial number), product name, product number, warranty period, lot number, manufacturing date, name of the orderer, name of the orderer's department, final packing location, and final packing date, etc. In addition to these information, the product information may include history information such as the sales history, repair history, and location history of the chair 1 with an electronic tag. The product information is updated at any time so that the latest product information is stored in the database 8.

[0028] The identification information (identification number) stored in the electronic tag 4 may be any identification information (unique identification information) written at the time of shipment (manufacture) of the electronic tag 4. In this case, in the database 8, the arbitrary identification information may be associated with the serial number etc. of the chair 1 with an electronic tag.

[0029] [Usage example of chair management system 100] Next, an example of using the chair management system 100 with the above-described configuration will be described. Hereinafter, an example will be described in which a user (seller) visits an office or the like of a consignee (purchaser) where a plurality of chairs 1 with electronic tags are installed, and conducts proposal activities such as replacement of the chairs 1 with electronic tags based on the identification information read from the electronic tags 4.

[0030] First, in an office where a plurality of chairs 1 with electronic tags are installed, the user operates a reading device 5 such as a handy reader to obtain identification information. For example, the reading device 5 irradiates the electronic tag 4 with radio waves while being held by the user, and reads the identification information from the electronic tag 4. At this time, since the reading device 5 reads the identification information non-contact by wireless communication with the electronic tag 4, it is possible to simultaneously obtain a plurality of identification information from separated positions. For example, when the reading range of the reading device 5 is about several meters, the identification information of the chairs 1 with electronic tags (electronic tags 4) within a range of several meters from the reading device 5 can be simultaneously obtained. Therefore, the identification information of the chairs 1 with electronic tags can be easily obtained. The reading device 5 transmits the read identification information to a communication terminal 6 such as a smartphone.

[0031] Next, the user operates a communication terminal 6 such as a smartphone to transmit the identification information to the server 7 through a network line from the consignee's office. When there is a plurality of identification information read by the reading device 5, the communication terminal 6 transmits each identification information to the server 7.

[0032] Next, based on the identification information transmitted from the communication terminal 6, the server 7 reads out the product information of the chair 1 with an electronic tag associated with the identification information from the database 8. The server 7 transmits the read product information to the communication terminal 6 through the network line. When there is a plurality of identification information transmitted from the communication terminal 6, the server 7 reads out a plurality of product information associated with each identification information from the database 8 and transmits it to the communication terminal 6.

[0033] Next, the communication terminal 6 displays the product number acquired from the server 7 on the display unit 61. Thereby, the user can perform proposal activities such as replacement of the chair 1 with an electronic tag based on the product information displayed on the display unit 61.

[0034] Note that the communication terminal 6 may display on the display unit 61 proposal activity information such as the date, month, and year when the proposal activity was performed in the past, the number of proposal times, and the next proposal timing. Thereby, the proposal activity can be performed at a more optimal timing. These proposal activity information may be stored in the database 8 as a part of the product information and transmitted from the server 7 to the communication terminal 6.

[0035] As described above, according to the chair management system 100, the identification information of the chair 1 with an electronic tag can be easily acquired, and based on the product information associated with the identification information, proposal activities such as replacement of the chair 1 with an electronic tag can be performed at an optimal timing.

[0036] Also, conventionally, for example, when the delivery destination office is transferred, information such as the location of the delivered chair cannot be traced from the sales history or the like, and it has been difficult to perform the above-described proposal activities. On the other hand, in the chair management system 100, product information such as the operation phase after delivery or the location after office transfer is shared between the user (seller) and the delivery destination (purchaser), and the database 8 storing these information is updated at any time. Thereby, since the operation phase or the location or the like can be continuously grasped, the proposal activity can be efficiently performed at an appropriate timing.

[0037] [Effect of Chair 1 with Electronic Tag] As described above, the chair 1 with an electronic tag includes a chair body 2 including a seat 21 and legs 22, and an electronic tag 4 provided on the chair body 2, the electronic tag 4 including a storage unit 31A that stores identification information unique to the chair body 2, and an antenna 32 capable of wireless communication with a reading device 5 that reads the identification information.

[0038] In the chair 1 with an electronic tag, since the identification information of the chair body 2 can be read by wireless communication between the electronic tag 4 and the reader 5, for example, it becomes possible to simultaneously acquire a plurality of identification information from separated positions. Therefore, according to the present embodiment, the identification information of the chair body 2 can be easily acquired.

[0039] [Embodiment 2] Hereinafter, an embodiment of the present invention will be described. For convenience of explanation, members having the same functions as those described in the above embodiment are denoted by the same reference numerals, and the description thereof will not be repeated.

[0040] [Configuration of Chair 1A with Electronic Tag] First, with reference to FIGS. 4 and 5, a configuration example of the chair 1A with an electronic tag according to the present embodiment will be described. FIG. 4 is a view showing the appearance of the chair 1A with an electronic tag according to the present embodiment. 4001 in FIG. 4 is a front perspective view in the unfolded state, and 4002 in FIG. 4 is a front perspective view in the folded state. FIG. 5 is a view showing the appearance of the chair 1A with an electronic tag. 5001 in FIG. 5 is a rear perspective view in the unfolded state, and 5002 in FIG. 5 is a rear perspective view in the folded state.

[0041] The chair 1A with an electronic tag according to the present embodiment is, for example, a folding chair used in an office, a conference room, a lecture hall, or the like. The chair 1A with an electronic tag includes a chair body 2A and an electronic tag 4 provided on the chair body 2A.

[0042] The chair body 2A includes a seat 21, a backrest 22, armrests 25, and rod-shaped (linear) front legs (legs) 24A and rear legs (legs) 24B that support these. The upper ends of the front legs 24A and the rear legs 24B are located above the seat 21. The front legs 24A and the rear legs 24B are made of a metal pipe such as a steel pipe, for example.

[0043] The seat 21 is in a plate shape. The seat 21 may, for example, have a structure of a single seat board made of synthetic resin or wood. Or, the seat 21 may have a structure in which a cushion material is laid on the seat board (inner shell), a structure in which a mesh material is laid on a frame body that is open top and bottom, etc. Similarly, the backrest 22 may be a molded product using synthetic resin or made of wood. Or, the backrest 22 may have a structure in which a cushion material is laid on the front surface.

[0044] Armrests 25 are integrally formed at both left and right ends of the backrest 22. That is, the backrest 22 and the armrests 25 have an integrated structure.

[0045] The upper end of the front leg 24A is fixed to the front end portion of the armrest 25. On the other hand, the rear leg 24B is connected to the armrest 25 so as to pivot back and forth with its upper end as a pivot point. Therefore, the front leg 24A and the rear leg 24B can be folded from a deployed state where the distance between them widens downward in a side view to a state where they cross in an X shape in a side view.

[0046] As shown in FIG. 5, the left and right front legs 24A are integrally fixed by left and right longitudinal front stays 28 at the height position on the back surface of the seat 21, and the front portion of the seat 21 is rotatably connected to the front stay 28. On the other hand, the left and right rear legs 24B are fixed via left and right longitudinal rear stays 29 at the height position on the back surface of the seat 21, and the rear stay 29 and the seat 21 are relatively rotatably connected via an interlocking member (link) 30 bent in a trapezoidal shape.

[0047] The seat 21 is supported front and back by the front stay 28 and the rear stay 29 in the deployed state. The front stay 28 and the rear stay 29 are made of metal pipes such as steel pipes and are fixed to the front legs 24A and the rear legs 24B by welding. When the rear end of the seat 21 is lifted, the seat 21 rotates with the front stay 28 as the rotation fulcrum, and in conjunction with this, the linkage member 30 rotates upward so that its rear end becomes higher. As a result, the rear leg 24B rotates relative to the front leg 24A, the seat 21, and the armrest 25, and the chair body 2A is folded. In this way, the seat 21 is a movable part whose position can be switched between a seating position (first position) where sitting is possible and a lifted position (second position) lifted from the seating position.

[0048] A handle rib 31 that a person can hang their fingertips on during the folding operation is provided at the left - right middle part of the rear end portion on the back surface of the seat 21. Further, the rear stay 29 is formed with a crank - shaped bent portion 29a that protrudes forward so as not to interfere when a person hangs their fingertips on the handle rib 31.

[0049] In this embodiment, the electronic tag 4 is provided on the back surface of the seat 21. As a result, the electronic tag 4 can be switched between a readable state in which identification information can be read by the reading device 5A (see FIG. 6) according to the position of the seat 21 and an unreadable state in which identification information cannot be read by the reading device 5A.

[0050] Specifically, as shown in 5001 of FIG. 5, when the seat 21 is in the seating position, the electronic tag 4 contacts the rear stay 29 made of a metal pipe or most of it is covered by the rear stay 29. In this case, the wireless communication between the electronic tag 4 and the reading device 5A is blocked by the rear stay 29, and the electronic tag 4 is in an unreadable state in which identification information cannot be read by the reading device 5A. On the other hand, as shown in 5002 of FIG. 5, when the seat 21 is in the lifted position, the electronic tag 4 is in an exposed state. In this case, the electronic tag 4 is in a readable state in which identification information can be read by the reading device 5A.

[0051] Therefore, based on the reading result (readability) of the identification information by the reading device 5A, it becomes possible to grasp whether the seat 21 is located at the seating position or the bouncing-up position. That is, when the reading of the identification information is impossible, it can be grasped that the seat 21 is at the seating position shown in 5001 of FIG. 5. On the other hand, when the reading of the identification information is possible, it can be grasped that the seat 21 is at the bouncing-up position shown in 5002 of FIG. 5.

[0052] [Configuration Example of Chair Management System 100A] Next, a configuration example of the chair management system 100A including the above-described chair 1A with an electronic tag will be described. FIG. 6 is a block diagram showing a configuration example of the chair management system 100A. As shown in FIG. 6, the chair management system 100A includes a chair 1A with an electronic tag, a reading device 5A, a PC (processing device) 6, and a database 8.

[0053] The reading device 5A is used to read the identification information from the electronic tag 4. In the present embodiment, the reading device 5A is a fixed reader attached to the ceiling, floor, wall, or desk, etc. in an office or the like where the chair 1A with an electronic tag is installed. The reading device 5A irradiates the electronic tag 4 with radio waves and transmits the read identification information to the PC (processing device) 7A by wire or wirelessly.

[0054] The PC (Personal Computer) 7A performs management processing of the chair 1A with an electronic tag based on the reading result of the identification information acquired from the reading device 5A. The PC 7A is, for example, a desktop PC or a notebook PC installed in an office or the like. The PC 7A includes a control unit 71 such as a CPU that controls the management processing of the chair 1A with an electronic tag, and a display unit (display) 72. As an example of the management processing, the PC 7A performs a process of detecting the position of the chair 1A with an electronic tag based on the reading result of the identification information read by the reading device 5A.

[0055] [Usage Example of Chair Management System 100A] Next, an example of using the chair management system 100A with the above-described configuration will be described. Hereinafter, an example of detecting the position of an empty chair 1 with an electronic tag in an office where a plurality of chairs 1A with electronic tags are installed will be described.

[0056] FIG. 7 is a plan view showing an office (space) 9 where a plurality of chairs 1A with electronic tags are installed. FIG. 8 is a schematic showing an example of the attachment of the reading device 5A installed in the office 9.

[0057] As shown in FIG. 7, the office (space) 9 includes an entrance 91, a refresh space 92, a workspace 93, and a meeting room 94. A PC 7A is installed near the entrance 91. Also, a plurality of chairs 1A with electronic tags and a plurality of reading devices 5A are installed in the refresh space 92, the workspace 93, and the meeting room 94. As shown in FIG. 8, a plurality of reading devices 5A may be installed on the ceiling, floor, wall, or desk 10 of the office 9.

[0058] First, a user who enters the office 9 operates the PC 7A to input an instruction to start detecting an empty chair 1A with an electronic tag. When this instruction is received, the reading device 5A irradiates the electronic tag 4 with radio waves and reads the identification information from the electronic tag 4. At this time, the identification information of the chair 1A with an electronic tag in which the electronic tag 4 is in a readable state, that is, the chair 1A with an electronic tag in which the seat 21 is flipped up and is in an empty state, is read by the reading device 5A located near the chair 1A with an electronic tag. The reading device 5A transmits the read identification information to the PC 7A together with the unique device information for identifying the device itself.

[0059] Next, based on the identification information and device information acquired from the reading device 5A, the PC 7A detects the position of the chair 1A with an electronic tag in the vacant state in the office 9. For example, the PC 7A stores in advance the position information of each of the plurality of reading devices 5A installed in the office 9. The PC 7A identifies the position of the reading device 5A that has read the identification information based on this position information and the device information. Then, the PC 7A detects the range where the chair 1A with an electronic tag in the vacant state is located based on the position of the reading device 5A that has read the identification information. For example, when the reading range of the reading device 5A is about 1 to 2 m, it is presumed that the chair 1A with an electronic tag in the vacant state is located within a range of 1 to 2 m from the reading device 5A that has read the identification information. Therefore, the PC 7A can detect the range where the chair 1A with an electronic tag in the vacant state is located in the office 9 based on the reading result of the reading device 5A.

[0060] Next, the PC 7A displays on the display unit 72 a screen indicating the range where the chair 1A with an electronic tag in the vacant state is located. For example, when a plurality of chairs 1A with electronic tags in the vacant state are detected, the PC 7A displays on the display unit 72 the plurality of ranges where the chairs 1A with electronic tags in the vacant state are located. Thereby, the user can grasp at which positions in the office 9 there are chairs 1A with electronic tags in the vacant state.

[0061] [Effect of the Chair 1A with an Electronic Tag] As described above, in the chair 1A with an electronic tag, the chair body 2A includes a seat 21 whose position switches between a seating position (first position) and a flipped-up position (second position), and the electronic tag 4 switches between a readable state in which the identification information can be read by the reading device 5A and an unreadable state in which the identification information cannot be read by the reading device 5A according to the position of the seat 21.

[0062] In the chair 1A with an electronic tag, based on the reading result (readability) of the identification information by the reading device 5A, it becomes possible to grasp whether the seat 21 is located at the seating position or the bouncing-up position. Therefore, according to the present embodiment, based on the reading result of the identification information, the usage state etc. of the chair 1A with an electronic tag can be grasped.

[0063] [Modification Example] The present invention may include a plurality of electronic tags. For example, in the chair with an electronic tag according to one aspect of the present invention, the first electronic tag and the second electronic tag may be provided on the chair body. In this case, when the seat is at the seating position, the first electronic tag becomes readable, and the second electronic tag becomes unreadable, while when the seat is at the bouncing-up position, the first electronic tag becomes unreadable, and the second electronic tag may become readable. Thereby, by using a plurality of electronic tags, it becomes possible to grasp whether the seat is located at the seating position or the bouncing-up position.

[0064] Further, the present invention is also applicable to objects other than chairs. For example, an electronic tag may be provided on an object such as a table or a mobile cart. Even in this case, the identification information can be easily acquired from the electronic tag provided on the object, and the object can be managed.

[0065] [Example of Realization by Software] The functions of the processing device (hereinafter referred to as "device") included in the chair management system according to the present invention can be realized by a program for causing a computer to function as the device, and by a program for causing a computer to function as each control block (particularly each part included in the control unit) of the device.

[0066] In this case, the device includes, as hardware for executing the program, a computer having at least one control device (for example, a processor) and at least one storage device (for example, a memory). By executing the program by this control device and storage device, each function described in each of the above embodiments is realized.

[0067] The program may be recorded on one or more computer-readable recording media, which are not transient. This recording medium may or may not be provided in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0068] Also, part or all of the functions of each of the control blocks may be realized by a logic circuit. For example, an integrated circuit in which a logic circuit functioning as each of the control blocks is formed is also included in the scope of the present invention. In addition to this, for example, it is also possible to realize the functions of each of the control blocks by a quantum computer.

[0069] 〔Summary〕 The chair with an electronic tag according to Aspect 1 of the present invention includes a chair body including a seat and legs, and an electronic tag provided on the chair body, the electronic tag including a storage unit that stores identification information unique to the chair body, and an antenna capable of wireless communication with a reading device that reads the identification information.

[0070] In the above configuration, since the identification information of the chair can be read by wireless communication between the electronic tag and the reading device, for example, it is possible to simultaneously acquire a plurality of pieces of identification information from a remote position. Therefore, according to the above configuration, the identification information of the chair can be easily acquired.

[0071] In the chair with an electronic tag according to Aspect 2 of the present invention, in the above Aspect 1, the chair body includes a movable part whose position is switched between a first position and a second position, and the electronic tag may be switched between a readable state in which the identification information can be read by the reading device and a non-readable state in which the identification information cannot be read by the reading device according to the position of the movable part.

[0072] According to the above configuration, it becomes possible to grasp which of the first position and the second position the movable part is located at based on the reading result (readability) of the identification information by the reading device.

[0073] In the chair with an electronic tag according to Embodiment 3 of the present invention, in the above Embodiment 2, the movable part is the seat that bounces and rotates around the rotation fulcrum, and the position of the seat may be switched between the first position where sitting is possible and the second position where the seat is bounced up from the first position.

[0074] According to the above configuration, for example, it becomes possible to grasp which of the first position (sitting position) and the second position (bounced-up position) the movable part is located at based on the reading result of the identification information by the reading device.

[0075] In the chair with an electronic tag according to Embodiment 4 of the present invention, in any of the above Embodiments 2 or 3, the electronic tag includes a first electronic tag and a second electronic tag. When the movable part is in the first position, the first electronic tag becomes in the readable state, and the second electronic tag becomes in the unreadable state.
