  The furniture system according to the present embodiment is mainly composed of, for example, the workstation 1 forming the work booth B positioned at a predetermined position in the office space.

  As shown in FIG. 1, the furniture system is applied to a workstation 1 formed by arranging the desks 10 such that the top plate 13 of the desk 10 is arranged in a horseshoe shape in a plan view, for example. A worker who works in the work booth B enters the work booth B through a single entrance / exit ST formed between the top boards 13 and performs work.

  Here, the furniture system according to the present embodiment includes a workstation 1 having a plurality of unit work spaces 1s, a plurality of chairs 3 arranged corresponding to each unit work space 1s of the workstation 1, and these A seating detector 2 provided in each chair 3 for detecting the seating of the office worker and generating a seating signal, and a unit work space 1s corresponding to the seated chair 3 receiving the seating signal from each seating detector 2 And a controller 4 for switching the lighting fixture 15 as a working fixture related to the above from a light-off state that is not in use to a light-up state that is in use.

  Hereinafter, each component, such as the workstation 1, the seating detector 2, the chair 3, and the controller 4, constituting the furniture system according to the present embodiment will be described.

  The workstation 1 forms a horseshoe shape in plan view, that is, a partial circumferential shape by attaching the ends of two desks 10 having a curved band shape in plan view to each other, thereby forming a work booth inside the horseshoe shape. In addition to forming B, the open part is set to the entrance / exit ST. The desk 10 includes a plurality of panel legs 11 arranged in a direction perpendicular to the circumferential direction, a curtain plate 12 that connects the panel legs 11 to each other at an outer edge, and is supported by the panel legs 11 and the curtain plate 12. And a desktop panel 14 made of, for example, a transparent or translucent plate provided so as to extend from the curtain plate 12 to above the top plate 13, and above the desktop panel 14. It has the lighting fixture 15 which is a work implement based on this invention located in the edge. In the present embodiment, the top plate 13 constitutes four unit work spaces 1s divided by broken lines in FIG. In other words, the workstation 1 has eight unit work spaces 1s so that eight people can work simultaneously. In this embodiment, eight lighting fixtures 15 are provided according to these eight unit work spaces. As described later, the lighting fixtures 15 are turned on / off for each unit work space 1s, that is, in a lit state / off state. Is switched. On the other hand, since the shape of the workstation 1 in plan view is a horseshoe shape in plan view surrounding the work booth B as described above, it is difficult to bring the chairs 3 out of the work booth B through the entrance / exit ST. Thus, the chair 3 is difficult to be carried to a distance that is excessively far from the unit work space 1s.

  As shown in FIGS. 1 and 2, a total of eight chairs 3 are arranged in the present embodiment in correspondence with each unit work space 1 s of the workstation 1. These eight chairs 3 have the same structure in this embodiment. The structure of the chair 3 will be described with reference to FIGS. The chair 3 is a so-called office rotary chair configured to be movable by a caster 35. As shown in the figure, the chair 3 includes a leg 31 having a caster 35 that can move on the floor, and the leg 31. A support base 32 supported at the upper end, and a seat 33 and a backrest 34 operatively supported by the support base 32 are provided. In this embodiment, as shown in FIG. 4, a detector installation portion 36 for installing the detector main body 20 that forms the main body of the seating detector 2 is provided on the upper portion of the support base 32. In addition, in the seat 33, as shown in FIG. 5, two switches 21 (to be described later) can be installed between the groove 39 provided on the upper surface of the seat cushion 37 and the upholstery 38 covering the seat cushion 37. It is configured.

  As shown in FIGS. 2 to 6, the seating detector 2 is provided in each chair 3 described above, and the switch 21 for detecting the seating of the worker, that is, the load on the seat 33, A transmitter 22 that transmits the load on the seat 33 detected by the switch 21 to the outside as a seating signal, and a pilot lamp 23 that causes a part of the backrest 34 to emit light in accordance with the load on the seat 33. ing.

  In the present embodiment, the seating detector 2 includes a plurality of, that is, two switches 21, and the plurality of switches 21 are arranged apart from each other in the front-rear direction as shown in FIG. If a load is detected, a seating signal can be transmitted. Specifically, the plurality of switches 21 are accommodated in a groove 39 provided in the seat cushion 37, and are covered with a tension fabric 38 together with the seat cushion 37, so that they are concealed so as to be inconspicuous in appearance. It is arranged. More specifically, these switches 21 are further provided with a plurality of, that is, four buttons 24. When any one of the four buttons 24 is pressed, the switch 21 detects a load. In other words, the switch 21 can transmit a seating signal when any one of a total of eight buttons 24 arranged in a distributed manner in front and back is pressed. This effectively avoids the problem that even if no load is applied to any of the buttons 24 due to a change in the posture of the seated person, the seating is not recognized by mistake.

  As shown in FIG. 4, the transmitter 22 is built in the detector body 20 disposed on the detector installation portion 36, and at least one of the two switches 21 receives a load from a seated person. The seating signal is issued when switching. Specifically, in a state where any one of the eight buttons 24 is pressed, the seating signal is intermittently transmitted once every 10 seconds, for example, for a period of less than one second. As a result, when the office worker is seated, the power consumption can be reduced rather than the mode in which the seating signal is always transmitted. The timing at which the transmitter 22 transmits the seating signal may be the timing at which the switch 21 receives a load. Of course, the transmitter 22 is previously set to 10 seconds within 10 seconds after the switch 21 is seated. It is good also as an aspect transmitted at the predetermined timing set for every.

  The pilot lamp 23 emits light from a part of the chair 3, specifically, a part on the back side of the backrest 34 when a seating signal is issued. By providing the pilot lamp 23, it is possible for each worker to easily determine whether the operation of the seating detector 2 is normal. Therefore, in the unlikely event that a malfunction occurs in the operation of the seating detector 2. In addition, any one of the office workers can respond promptly. The pilot lamp 23 is turned on in order to avoid unnecessary blinking caused by a temporary leaving of the seated person or a change in posture even when the pilot lamp 23 is energized as it is by detecting the load by the switch 21. Alternatively, the lighting may be continued for 10 seconds or more from the timing at which the seating signal transmitted intermittently is transmitted. The detector main body 20 incorporating the transmitter 22 incorporates other components such as a battery (not shown) for supplying power to the transmitter 22 and the pilot lamp 23, but in the present embodiment, details thereof are provided. Such explanation is omitted.

  The controller 4 receives the seating signal from the seating detector 2 and uses the lighting device 15, which is a working device related to the unit work space 1 s corresponding to the chair 3 being seated, from the non-use state to the use state. The lighting state is switched to the lighting state to provide a brightness sufficient to suitably perform work in the unit work space 1s. As an example, the controller 4 is illustrated as being placed inside one desk 10 as shown in FIG. 1, but of course, it is installed at a different position outside the workstation 1 and adjacent to it. It may be associated with other workstations 1 or may be associated with all the workstations 1 in the office collectively. Next, the configuration of the controller 4 will be described.

  As shown in FIG. 6, the controller 4 includes a receiver 41 that can receive a seating signal, and a determination circuit 42 that determines which unit work space 1s the seating signal received by the receiver 41 is associated with. The standby circuit 43 for determining the lighting / extinguishing state of the corresponding luminaire 15 from the seating signal transmitted intermittently as described above, and the unit work space 1s is arranged according to the determination of the standby circuit 43. Each lighting fixture 15 has a switching circuit 44 that switches between a lighting state that is a use state and a non-use state that is a non-use state.

  The receiver 41 receives a seating signal that is intermittently transmitted from the transmission circuit every 10 seconds. However, the frequency and data processing modes in which the transmitter 22 and the receiver 41 communicate wirelessly are existing. In this embodiment, detailed description will be omitted because it is compliant with any one of the communication methods.

  The discrimination circuit 42 is for specifying the lighting fixture 15 corresponding to the received seating signal, and in this embodiment, as an example, the lighting fixture 15 and the chair 3 positioned in the unit work space 1s are 1: 1. It is related with. However, the association between the chair 3 and the lighting fixture 15 by the discrimination circuit 42 is not limited to 1: 1. For example, the four lighting fixtures 15 included in any one of the desks 10 may be turned on or off depending on the presence / absence of a seating signal for any one of the chairs 3. In addition, for example, the luminaire 15 in the unit work space 1s closest to the chair 3 that transmitted the seating signal may be turned on.

  The standby circuit 43 is configured to turn on the luminaire 15 for 10 seconds or more by receiving a seating signal received every 10 seconds. Thereby, even if the load on the switch 21 is temporarily lost due to the temporary leaving of the seated person or the posture change, the lighting fixture 15 can be stably maintained in the lighting state.

  The switching circuit 44 switches the lighting state / extinguishing state of the eight lighting fixtures 15 of the workstation 1 as described above according to the operation of the determination circuit 42 and the standby circuit 43. Such a mode may be a mode for directly controlling energization to the eight lighting fixtures 15 or a mode for controlling indirectly. Indirect control of energization to the lighting fixture 15 is a mode in which, for example, the lighting / extinguishing states of the eight lighting fixtures 15 connected to the power source in advance are controlled by remote control or the like.

  In the furniture system having the configuration described above, for example, when an office worker is seated on any one chair 3, any one of the four switches 21 provided on any one of the two switches 21 is provided. After the button 24 is pressed, the pilot lamp 23 of the chair 3 blinks and a seating signal is transmitted intermittently once every 10 seconds. When the transmitted seating signal is received by the receiver 41, the determination circuit 42 determines which unit work space 1s corresponds to the seating signal. At the same time, the standby circuit 43 lights the lighting fixture 15 as a working fixture for 10 seconds or more, and determines that the lighting fixture 15 is turned off when no seating signal is received for 10 seconds or more. Then, the switching circuit switches the lighting / light-off state of the lighting fixture 15 according to the determination of the standby circuit 43. In this way, if the worker sits on the chair 3, the unit work space 1s of the worker himself will be brightly illuminated by the lighting device 15, and the worker can start working smoothly after sitting. it can.

  With the configuration as described above, the furniture system according to the present embodiment switches between the use state and the non-use state in association with the unit work space 1s of the lighting device 15 as a work tool, so that the office unit or workstation Since it is possible to take action corresponding to the working status of the office worker by avoiding operating the work equipment by one unit, it can contribute to energy saving of office work as a result. .

  In the present embodiment, the unit work space 1 s is positioned based on the top plate 13 provided on the desk 10, so that the worker can easily recognize the worker's own work position in the workstation 1. You can start working smoothly.

  In this embodiment, in order to prevent the association between the plurality of unit work spaces 1 s and the plurality of chairs 3 in the workstation 1 from being disturbed by taking out the chair 3 from the vicinity of the workstation 1, The station 1 is arranged so as to surround the work booth B where the chairs 3 are arranged, and an entrance ST to the work booth B is formed in a part thereof.

  Further, the work implement according to the present invention is not limited to the lighting fixture 15 for illuminating the unit work space 1s, and an individual air conditioner that operates only by an outlet or the unit work space 1s may be applied. Therefore, the office worker can easily recognize the range of the location of the unit work space 1s, and can quickly perform work using the area illuminated by the lighting device 15.

  In the present embodiment, the seat detector 2 is configured so that the plurality of switches 21 disposed on the seat 33 of the chair 3 and at least one of the switches 21 are switched by receiving a load from the seated person. This effectively avoids the problem that the seating signal is not transmitted by mistake due to the posture change while the person is sitting. In addition to this, in the present embodiment, by applying a configuration in which the lighting fixture 15 is turned on for 10 seconds or more by receiving a seating signal transmitted intermittently every 10 seconds, Even when the seating signal is not transmitted due to a large posture change, the problem that the lighting fixture 15 is temporarily turned off and interferes with the work of the office worker is effectively avoided.

  In the present embodiment, the seat detector 2 is provided with the pilot lamp 23 in which a part of the backrest 34 is turned on when the office worker is seated, so that whether or not the seat detector 2 is operating correctly is determined. It can be easily confirmed by the staff of the station 1.
