Description

  The present invention relates to a bed apparatus configured to supply power for driving a drive unit by a manual power generator.

In a bed device for care or medical use, various power-use devices such as an electric actuator for a bed driving unit and a measurement device for a care recipient or patient (hereinafter referred to as “care recipient”) are installed.
Caregivers and nurses (hereinafter referred to as “caregivers”, etc.) raise the back bottom so that the upper body can be raised about the posture of the cared person etc. on the bed device, and the knee bottom to ease the legs And the leg raising operation of raising the leg bottom is performed. Usually, in daily work performed by a caregiver or the like, a back-up operation is always required after waking up or every meal, so the number of back-up operations is greater than other operations.

  When the operation of the bed device such as raising the back is performed with a mechanical handwheel, the motor operation is usually performed because it tends to be a work load for a caregiver or the like. As the power source for operation in that case, generally, a power source in a facility where a bed apparatus such as a nursing facility or a hospital is installed is used as described in Japanese Patent Application Laid-Open No. 2008-220603 (referred to as “Patent Document 1”). .

  In addition, the power supply in the facility is often installed on the wall near the bottom, preventing the power cord from touching the floor and making it unsanitary, or pinching the power cord between the bed lifting devices. In order to prevent such a problem, a cordless power supply device that generates power using a solar cell (solar panel) has been proposed by Japanese Patent Application Laid-Open No. 2011-160888 (referred to as “Patent Document 2”).

  However, when using solar cells, the installation location is limited because it is necessary to make it an installation location that can secure sufficient power generation in a room that is difficult to receive sunlight, and a battery that charges (stores) generated power is required. It will increase in size.

  Therefore, the inventor has devised that a power generation device (hereinafter referred to as “manual power generation device”) as a power supply for the bed apparatus is used as a power supply for the bed apparatus.

Since the manual power generator is driven by a caregiver or the like by hand, there is a request to manually drive the power generator at a location that does not cause a work load on the caregiver or the worker. In particular, the work of raising and lowering the back of the back is frequently performed at nursing and assistance sites, so there is a high demand for work efficiency.
In addition, there has been a request that the power supply destination of the manual power generator can be supplied to the drive units of various drive systems, and that at least a back operation drive unit can be driven by generating power (electric power) even during a power failure.

In addition, it is necessary to reduce the time and physical burden of wiring work between a power-generating device such as an electric actuator and a manual power generator. Simply connecting a manual power generator to an electric actuator requires that the person (operator) who performs the connection work dive under the bed and connect a dedicated connector, which places time and physical burden on the wiring work. there were.

The box 50 is installed as a footboard 9.

FIGS. 9A to 9C are explanatory diagrams of a structure example of the manual power generator 52.
As shown in FIG. 9 (a), the manual power generator 52 has a shaft 52c for inserting a handle (also referred to as "crank") 52b having a substantially rod shape and a spherical tip so that the main body 52a can be grasped with one hand. Is protruding. The manual power generator 52 can be removed from the shaft 52c so that the manual power generator 52 can be easily carried when not in use. The removed handle 52b can be fixed to the side of the main body 52a by folding the handle. A cord (power line) serving as the first power supply path 52d comes out of the main body 52a, and a plug is provided at the tip of the first power supply path 52d.

As shown in FIG. 9B, when the manual power generator 52 is used, the handle 52b is fitted on the shaft 52c, and the handle portion held by the hand of the handle 52b is developed.
Then, as shown in FIG. 9 (c), the plug of the power supply path 52d is inserted into the insertion socket 50a of the relay box 50, and is rotationally fixed and connected. The power generated by the manual power generator 52 in this inserted connection state is supplied to the back motion electric actuator 31 via the power path 58 of the relay box 50.

  The power supply path of the first embodiment is such that the first power path 52d of the manual power generator 52 provided separately from the bed apparatus 1 and connected to the relay box 50 is connected to the relay box 50, and the second power path ( The electric power generated by the manual power generator 52 is supplied to the electric actuator 31 for back operation, which is an example of one output destination, via a power cable 58. Various modifications such as providing a switch for switching between the manual mode and the electric mode (manual / electric switching switch means 61: see FIG. 10) in the power supply path are also within the scope of the first embodiment.

  FIG. 10 is an explanatory diagram of each wiring example of the power supply path included in the first embodiment, where (a) shows a first example, (b) shows a second example, and (c) shows a third example. ing.

  In the first example shown in FIG. 10A, power can be supplied from the control box 40 provided in the bed apparatus 1 to the back motion electric actuator 31, the lift electric actuator 32, and the leg motion electric actuator 34 in the electric mode. As described above, the power supply paths in the electric mode are connected to each other, but the power supply path in the electric mode to the electric actuator 31 for back movement is from the electric line 40a to the second power supply path 58 via the relay box 50. It is.

(1) A manual / electrical changeover switch means 61 is built in the relay box 50.
(2) The manual / electrical changeover switch means 61 uses a mechanical switch or an electrical switch.

  (3) When a mechanical switch is used for the manual / electrical changeover switch means 61, as one configuration, by inserting the power supply plug of the first power path 52d of the manual power generator 52 into the socket 50a of the relay box 50, A structure in which the manual line (second power supply path 58) can be switched from the electric line 40a extending from the control box 40 can be achieved. For example, a manual line / electrical line is switched by providing a tact switch or the like around the socket 50a of the plug insertion port.

  As another configuration, manual / electrical switching can be performed by operating the operation switch unit by providing the relay box 50 with a manual / electrical switch unit 61 with an operation switch unit such as a rotary or toggle switch exposed. The switch means 61 can switch between the electric mode and the manual mode.

The operator can easily reach out, and the operator can easily perform the power generation work when the manual power generation device 52 generates power. Moreover, since it becomes easy to perform power generation work, time and physical burden can be reduced. In addition, since the relay box 50 is provided at a location facing the outside in the horizontal direction and reachable by the user, connection work can be facilitated.

  It should be noted that during normal use (in the electric mode) when the manual power generation device 52 is not used, the power supply to the drive unit of the back motion electric actuator 31, the lift electric actuator 32, the leg motion electric actuator 34, and other power-using devices. The supply path can be driven by power supplied from an indoor power outlet via a power path through the control box 40 or a relay box (not shown).

  It is an example of the present invention that the relay box 50 is provided on the foot board 9 in the first embodiment, and the relay box 50 is any part of the foot side, head side, and side side of the bed apparatus 1. Thus, it is also within the scope of the present invention to appropriately arrange the parts that face the outside in the horizontal direction and can be reached by the user.

  For example, the installation location of the relay box 50 can be provided in the foot side portion of the bed frame 3, and the deformation is provided by being embedded (or protruded) in the side rail 7 on the side as in the bed apparatus 1 in FIG. 11. Example 1 can be taken.
