Preferred embodiments of the apparatus of the present invention are disclosed in detail below. It should be understood that the present invention is not limited by the details of the order of the application, or the order of the steps of the work, or the performance of the method and / or the details of the structural arrangement, This is to be described in the specification, drawings or examples described below. Although specific steps, configurations, and arrangements are discussed, this should be understood as illustrative. Those having skill in the relevant arts will appreciate other steps, embodiments, configurations, and arrangements without departing from the spirit and scope of the present invention.

The present invention is also possible in practice and execution by other embodiments and various methods. It should also be understood that the wording, terminology, and notation employed herein are for the purpose of description and should not be considered limiting.
Older people have difficulty bending their hips or moving from standing to sitting, and vice versa.

People with serious knee problems are similarly difficult to bend their knees. As a result, it is difficult to sit on the bed.
Overweight or obese people sometimes find it difficult to bend their knees when sitting in the bed and are difficult to get up from the bed.
Hereinafter, for the sake of brevity, the terms “bed” and “multi-position bed” and “multi-position support device” shall have the same meaning without limiting the scope of the present invention. .

The multi-position support device having the electric foot support according to the present invention is configured so that the bed is placed in a reclining state or a horizontal state from a state where the user is standing (that is, both the bed and the user are substantially vertical). The user is received and laid without optionally using the user's binding means or fixing means before the angle change occurs.
In an exemplary embodiment of the invention, the multi-position support device is movable by providing wheels. In an alternative alternative embodiment of the invention, the wheel that allows the bed to move may be electrically powered. In the case where the wheels that make the bed movable are motorized, the movement of the bed can be controlled using a control panel. The control panel allows a user to operate a plurality of different engines independently, and further allows the user to transition from a standing state to a sitting state and from a sitting state to a standing state. In addition, a transition from a standing state to a lying state, a transition from a lying state to a standing state, a transition from a sitting state to a lying state, and a transition from a lying state to a sitting state It is possible to perform the following operations.

  As shown in FIGS. 1 and 2, a novel main part according to the present invention is an electric foot support 17. In order to prevent the user from being caught when the bed is displaced from the horizontal state to the standing state or when the bed is displaced from the sitting state to the standing state, the electric foot support 17 is used. It is important to have When the user wants to stand from a lying or sitting state, the electric foot support 17 moves in the direction of the bed head until reaching the user's leg. The electric foot support 17 may be arbitrarily operated by the motor 21.

  Various novel methods can be used to detect when the foot support has reached the user's foot lying on the bed. For example, a pressure sensor that measures the strength of the resistance of the user's leg can be used. The minimum resistance value measured by the sensor is set to a sufficient value so that the electric foot support 17 actually reaches the user's leg and does not reach other objects that tend to be on the bed. Should be. For example, as a safety precaution, it is important to ensure that the user is not moved to a standing position while using a blanket or pillow.

On the other hand, when the user wants to stand while using a blanket or a pillow, the pressure sensor may imply that the other object is pushing the leg so that the minimum pressure value is applied in advance. Should be set to ensure. Only when an appropriate pressure value is measured on the sensor, the bed begins to wake up.
In an exemplary embodiment of the invention, it is possible to abandon the movement of the leg support if the user wishes to move from lying to sitting. The bed of the present invention also moves when the pressure value measured by the sensor falls below a pre-determined pressure value requesting to start moving from a lying state to a standing state. It can be a starting point.

  In an exemplary embodiment of the present invention, when the user wants to move to a standing position, the multi-position support device moves the angular position at the same time as the leg support moves toward the head of the multi-position support device. Start the change. Performing these two operations simultaneously saves time, and further allows the electric leg support 17 to reach the user's leg within a reasonable time with respect to the angular position of the multi-position support device. It does not endanger the user.

When the multi-position support device reaches a predetermined angle, the electric leg support starts to descend. As a result, when the user moves to a standing state, the user's feet are in close proximity to the ground. This operation is intended to prevent the user from falling off the step.
The power unit of the electric foot support 17 can be positioned on the lower side or the side of the multi-position support device.

  As shown in FIGS. 1, 2, 3, and 4, in an exemplary embodiment of the invention, the motorized foot support 17 is connected to the operating engine through the mattress insertion port. The electric foot support 17 is connected to an operation engine (not shown) using at least one arm-shaped extending portion that reaches at least one side of the multi-position support device. In this alternative embodiment, no mattress is required to be inserted.

As shown in FIG. 2, the electric foot support 17 can move along the shaft 300 or the shaft 301.
The bed of the present invention can also be used as a chair. In an exemplary embodiment of the invention, the bed can be transformed into a sitting state such as a reclining chair.

As shown in FIG. 3, the features of the embodiment of the bed of the present invention are at least as follows.
(A) A foot support that is movable in the head direction when the bed is in a state other than the standing state, and is movable in the ground direction when the bed is in a standing state (for example, a substantially vertical state). 17,

(C) Optionally, the multi-position support device in a state covered with a mattress. In another embodiment, the mattress is mounted using means for attaching the mattress to a bed according to the present invention. Typical attachment means are nails, screws, hooks and fasteners.

In an exemplary embodiment of the invention, the bed comprises a toilet bowl. Optionally, when the toilet bowl is used, the bed moves to a sitting state. Optionally, the use of the toilet is indicated by the user through a control panel (not shown).

In an exemplary embodiment of the invention, a foldable tray is attached to the multi-position support device. This foldable tray can be used as a table on which various items such as food, drinks, dishes, books, remote controls, telephones, computers, alarm clocks and the like can be placed.
The foldable tray may be folded by any method in the prior art. Optionally, when changing the angular position of the bed, the foldable tray may be moved aside manually by the user or by an engine powered by conventional known methods. Alternatively, it is preferable that when the multi-position support device is deformed, the one placed on the tray does not fall.

  In another exemplary embodiment of the present invention, the bed can be raised vertically (up and down). The ability to raise the bed vertically is useful and convenient when the user is undergoing outpatient treatment, undergoing physical examination, undergoing treatment, receiving a massage, or undergoing any other known procedure. is there. By raising or lowering the bed, the height of the bed can be adjusted according to the caregiver.

  In another exemplary embodiment of the present invention, the bed armrest is not secured to other moving parts. By doing in this way, the user can put a blanket and other various things on the armrest before the bed moves from one state to another state. Optionally, various things can be placed on the bed, especially when shelves and trays are moved from one state to another so that they are not dropped. You may prepare.

FIG. 7 shows the angle of the multi-position support device 10 in the standing state. Angle 41 is greater than 180 degrees to prevent the user from falling off when standing or entering standing. The angle 40 should be smaller than 180 degrees, but should not be smaller than a predetermined angle, and this angle is entirely dependent on the angular position of the multi-position support device 10.

The control system of the system according to the present invention functions to prevent the user from manually reducing the angle beyond 40 degrees which can drop out in front of the multi-position support device.
By using the present invention, the possibility of an accident is very low. By receiving the user in a standing position and returning it in a standing position, the possibility of an accident related to the bed occurring is minimized.
It will be appreciated that the present invention is useful for those who cannot stand. In such a case, the present invention receives the user in a sitting state and returns it in a sitting state.

  Changing the angle early can cause dizziness in the elderly. This phenomenon is known as orthostatic hypotension. Optionally, the speed at which the multi-position support device 10 changes its angular position is such that the user feels comfortable and can be controlled or adjusted according to health conditions. Optionally, when the angular position changes, the user can stop the device using a control panel or other control device.

  In addition, the elderly may suffer from orthostatic hypotension while changing from lying to standing. As a result, the elderly will feel weakness, reduced muscle tone and even the possibility of fainting. The user may fall out of bed due to a decrease in muscle tone when moving to a sitting state. When shifting from a lying state to a standing state, the user is leaning against the bed until the user is standing. Reduced muscle tone creates the risk of slipping down or to the side of the bed, and even dropping forward.

In an exemplary embodiment of the present invention, the bed is provided with a muscle tension detecting device for the purpose of reducing muscle tension and preventing dropout. Muscle tone detection is performed using a variety of conventional techniques.
When the muscle tone monitoring device detects a serious decrease in the user's muscle tone, the bed automatically returns the user to a safe reclining state. In an exemplary alternative embodiment of the present invention, the bed prevents the user from falling off by the method described below.

Optionally, an electric protective wall that lifts upward may be provided on the side of the bed to prevent the user from sliding down to the side.
As shown in FIG. 2, the electric foot support 17 moves forward on the shaft 301 and pushes the user's foot. In this way, the user's foot is used as a lever to prevent the user from falling forward. Furthermore, this lever effect assists the user's body to lean against the bed.

  Optionally, pushing the user's knee forward will result in bending of the knee. According to the foot pushed forward, the user moves to a safe position. It is important that the knee and foot are pushed forward in comparison with the bed body moving backwards. In this way, the bed fully supports the user's body by maintaining sustained contact with the user. By maintaining continuous contact with the user and not creating a gap between the user's body and the bed, the likelihood of falling off the bed is reduced.

In this way, the bed is gently returned to the reclining state while maintaining continuous contact with the user's body.
FIG. 1 illustrates an exemplary selection of a multi-position support device 10 that can move into a standing, sitting, and reclining state.
The engine is connected to various parts of the multi-position support device 10. For example, the engine is connected to the back support 11, the seat 14, and the leg support 16. In another alternative embodiment (not shown), it has an engine connected to the shaft of the device. For example, the two engines may be connected to the back-seat corner 13 and the seat-leg 15.

  The angles of the back support 11, seat 14 and leg support 16 will vary during operation to achieve maximum stability and minimize pressure on the legs. In an alternative embodiment of the invention, the user enters the device in a standing position and leans back, where the device sits down at an angle of 20 to 60 degrees. Start moving to the state. When the device moves from a sitting state to a standing state, the user is first moved to a tilted position of 20 to 60 degrees and then moved to a fully standing state.

  An optional embodiment of the present invention prevents the situation where the multi-position support device 10 crushes the foot of an operator who is not a user, such as a nurse. One or more sensors are provided on the leg support 17. The one or more sensors detect an object and prevent the leg support 17 from crushing the object. Sensors to be selected include, but are not limited to, infrared sensors, motorized steps that send signals when a foot touches, microswitches, cameras, and other known techniques.

Another optional embodiment of the present invention prevents situations where the back support 11 crushes an operator who is not a user, such as a nurse. One or more sensors are provided on the back support 11. The one or more sensors detect an object and prevent the back support 11 from crushing the object. Sensors selected include, but are not limited to, infrared sensors, motorized steps that send signals when contacted, microswitches, cameras, and other known techniques.
In order to achieve the reclining state (180 degrees), by providing a recess in the pivot shaft region, the pivot shaft will fall into the recess when the multi-position support device is extended according to the required reclining state Is possible.

  Optionally, the armrest of the multi-position support device according to the present invention can be moved upward, downward and sideward to enhance the user's comfort. Optionally, the armrest may be separated from the multi-position support device. In this case, when the multi-position support device moves, the armrest does not move according to the operation of the multi-position support device, but comfortably reaches the object and the shelf while the user moves the position. It makes it possible.

As in the selected embodiment shown in FIG. 8, the multi-position support device is moved from a standing state to a sitting state by using one engine and a parallelogram base structure, or from a sitting state. It was possible to move to the reclining state.
Parts 80 and 90 operate rods that can be lengthened or shrunk. As the length of the rod increases, the device moves to the reclining state.

In the alternative embodiment shown in FIG. 9, the leg support and the back support move together so that the first engine is used for both. The second engine is used to change the angle of the multi-position support device.
FIG. 9 shows a parallelogram basic structure apparatus using two engines. The operation of the first engine is the same as that of the parallelogram foundation structure device using one engine. By operating the second engine, the parallelogram foundation structure device is raised or laid down. Reference numeral 101 denotes an engine for shifting from a sitting state to a standing state.

The device is fixed to the shaft 103.
The purpose of the power unit 102 is to move the device from a sitting state to a lying state.
In this parallelogram structure device, 104 and 105 are parallel and move vertically. In the non-parallelogram structure device, each part may be controlled independently or almost independently.

In the selected embodiment of the present invention shown in FIG. 1, the engine 23, 24, and 25 shows a state in which the angular position of the multi-position support device is determined.
By using three or more engines to control the angular position of the multi-position support device 10, it is possible to further adjust the movement of the multi-position support device 10 for further user comfort. is there.

The multi-position support apparatus 10 may have three or more separate and independent engines.
In an exemplary embodiment of the present invention, the multi-position support device 10 has various lengths to provide various heights for the user. Therefore, the length of the multi-position support device 10 is adjusted according to the height of the user. Adjustment of the multi-position support device 10 according to the height of the user can be achieved by adjusting the lengths of the leg support 16 and the back support 11.

When the multi-position support device 19 moves from the sitting state to the reclining state, the user's body moves smoothly downward. This action can cause unpleasant friction against the background. In order to prevent this friction, the multi-position support device can move according to the movement of the user. For example, it is assumed that the movement of the back of the bed follows the movement of the back of the user. As shown in FIG. 5, the back support portion 62 varies above the back support portion frame 60. In selected embodiments of the present invention, the mobility of the back support 62 above the back support frame 60 is achieved by the slide 61.
In an exemplary embodiment of the present invention, at least one of the head support part, the back support part, and the leg support part may be a movable part.

In another option, the movable part is achieved by using a selection embodiment described below.

(A) Two or more trajectories. Hereinafter, “orbit” refers to any device capable of moving along a specific direction.
(B) The spring supporting the movable part is a typical solution to ensure that the movable part does not move independently. In order to prevent a quick movement by the spring, for example, the spring can be combined by a piston.

(C) A telescopic device is used. A typical telescopic device is a shock absorber used in a luggage compartment (trunk) of a motorcycle or an automobile. The functionality of the telescopic device ensures that the support does not move on its own or that it does not move independently when the user wakes up temporarily.
It should be understood that the use of a telescopic device is merely an example, and the moving part can be implemented by other known techniques. Other known techniques include, but are not limited to, wheelchair techniques disclosed as background art of the present invention. Unless a command to change the angular position of the multi-position support device 10 is given or the engine does not work, the position of the movable part on the slide is fixed. This is accomplished with pins, step power, electromagnets, and the like. In this case, since the movable part does not move independently, the telescopic device is not necessary.

The movable part moves along at least one orbit. What is selected may be one track below the middle section, two tracks below the back side, or any other equivalent implementation.
Instead of using a movable part, it is also possible to use a device that operates on an orbit with an engine. This is made possible by the fact that the distance that the user's back should move depends on the angular position of the chair device and can therefore be measured in advance.

The starting position of the movable part can be determined according to the height of a specific user. In this case, the multi-position support device according to the present invention is adjusted according to different user heights by moving the movable part according to the height of the user. As the height of the user is higher, the starting position of the movable part in the standing state of the device is further away.
Next, the movable part of a typical multi-position support apparatus will be described.

As shown in FIG. 1, the parts 11 and 14 are close to each other in a standing state.
The following example shows the operation of each part to prevent unpleasant friction when changing the angular position of the device. When an active control system that controls the position and operating state of the moving part is used, the parts 11 and 14 move closer together as the device moves from a sitting state to a reclining state.

  Another option is to use moving parts without using active control. The movable part is provided on (in contact with) the slide. When the user sits, the parts 11 and 14 move away from each other. When the user lies down, the parts 11 and 14 move in a direction close to each other. That is, when moving from a standing state to a sitting state, the parts move away from each other, and when moving from a sitting state to a reclining state, the parts move closer to each other. It is something that moves.

It will be appreciated that the moving part solution as a typical method can be implemented on any user's body support, including back seat and foot support. Since related operations are necessary, at least one of the back support portion and the leg support portion may be a movable portion. In this case, since at least one of the back support portion and the leg support portion moves, the seat does not need to move.
