[Composition] A bed equipped with a human sensor switch for detecting only the outer contour of the bed, a lighting device interlocking with the human sensor switch, and an alarm device on the side surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to beds used in homes, hospitals, welfare facilities and the like.

[0002]

[Prior art]

 Conventionally, the bed surroundings were equipped with pull switches and toggle switches at the bedside only to illuminate the bed users' hands.

In addition, when a user gets on a bed, the weight of the user automatically turns off the light, and when the user gets up from the bed, the light turns on. There is a bed equipped with it.

[0004]

[Problems to be solved by the device]

 However, with conventional bed lighting, it was not possible to obtain sufficient illuminance to illuminate the feet when entering and leaving the bed at night, which was dangerous when leaving the bed and walking at night. In addition, it is painful to search for a switch for lighting in the dark, and the nightlight that is generally used as a countermeasure at present is not practical because the illuminance is not sufficient, and it is constantly lit at night. This is uneconomical and may even cause discomfort to bed users.

As a countermeasure, there is a conventional technology of the above-mentioned weight sensor or bed with a weight switch, but when the user leaves the bed, the lighting does not work, and the safety of the feet of the user who left the bed at night Cannot be secured.

[0006]

[Means for Solving the Problems]

 As a means for solving the above problems, the present invention provides a human sensor switch using an infrared detection element on a side used by a user to enter and leave a bed used in a house, a hospital, a welfare facility, and the like. It is intended to provide a foot light driven by a sensor switch or a bed equipped with a foot light and an alarm.

[0007]

[Action]

 As described above, the bed of the present invention has a motion sensor on its side, and the detection area of the motion sensor extends from the outside of the bed to the outside, so that the human body is completely on the bed. If there is no human body moving near the bed, the foot lights on the side of the bed will be turned off automatically. In addition, when the user tries to get out of bed and hangs his / her foot on the side of the bed, the foot sensor lights up immediately by the motion sensor to illuminate the user's foot and, in addition, to detect the user approaching the bed. Even when the sensor detects it, a foot light that functions as a guide light to the bed lights up and illuminates the feet of the bed user and the nurse. Therefore, by illuminating the feet when entering and leaving the bed at night, the safety of the user is improved and the convenience of the user is improved by eliminating the need to touch or search for the lighting switch. Improve the safety and efficiency of nurses even during nighttime nursing. In addition, it is possible to save energy without hindering the safety, convenience and efficiency.

Further, by adding an alarm device driven by a motion sensor, the motion sensor detects that a user is approaching the bed and generates a sound, so that a person with a visual disability can reach the bed. It becomes possible to induce. In addition, by connecting the alarm device to centralized management functions such as hospitals, welfare facilities, and security companies, it is possible to detect abnormalities such as sick people and old people who are forced to stay on the bed and leave the bed or fall. It is possible to improve the safety of users.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1, 2, and 3 are external views of the bed of the present invention. In each figure, 1 is a bed main body, 2 is a human sensor switch using a pyroelectric infrared detector capable of detecting a range of 180 degrees, 3 is a lighting unit, 4 is an alarm device, and 5 is the alarm device 4. The changeover switch for switching the operation of is shown. Reference numeral 6 denotes a detection area of the human sensor switch unit 2, which is a range for detecting infrared rays from the human body. In the present embodiment, the lighting unit 3 has a built-in rechargeable battery B1 and can be attached to and detached from the bed body 1 together with the rechargeable battery B1 and can be used as a portable device in an emergency such as a power failure. It has been raised to. In the detection area 6, the motion sensor switch unit 2 detects a person's foot trying to get out of the bed or a person approaching the bed, and drives the lighting unit 3 to quickly illuminate the person's foot to detect the vicinity of the bed. Make walking easier. In addition, if the changeover switch 5 is closed, when the human sensor switch detects a human body, the alarm device 5 emits an alarm sound or an alarm signal.

FIG. 4 shows a circuit diagram of the human sensor switch unit 2, the lighting unit 3, the alarm device 4, and the changeover switch 5 of the bed of the present invention. The human sensor switch unit 2 has a pyroelectric infrared detector 8 and an illuminance detector 9 built-in, and a timer circuit 11 driven by its output. When the human sensor switch unit 2 detects the movement of the human body when the ambient illuminance becomes darker than a certain value, the switch SW1 is closed for a time set by the timer circuit 11 to turn on the illumination L1. Note that the timer circuit 11 is in the retriggerable mode, and the timer is constantly reset while the human body in the detection area 6 is moving, and the illumination L1 continues to be lit while the person is moving. Therefore, if the area around the bed is dark to some extent, the foot lamps will be continuously lit when the user moves in and out of the bed. The lighting unit 3 has a power failure detection circuit 12, a switch SW1 that is closed by the output of the power failure detection circuit 12, and an illumination L1 that is turned on when the switch SW1 is closed. If so, the rechargeable battery B1 is charged through the resistor R1. When the power supply 7 is no longer energized, the power failure detection circuit 12 forcibly closes the switch SW1 and lights the illumination L1 with the power of the rechargeable battery B1 through the diode D3. Therefore, in the event of a power failure due to a disaster, it will be used as an emergency light to automatically illuminate your feet as soon as electricity stops, and when the lighting unit 3 is removed from the bed body 1, it will be automatically lit immediately and flashed. It becomes an electric light.
