Description

Technical Field

[0001] The present invention relates to a self-service escort bed, belonging to the technical field of medical escort. Background Art

[0002] An escort bed is a public facility placed in a hospital ward for the use of those accompanying inpatients to rest within the time set by the hospital. Limited by the size of the space in the ward, the escort bed is usually set as a foldable structure, or stored in the space under the hospital bed board when not in use, and taken out from under the hospital bed when needed.

[0003] An existing technology 1 discloses a hospital bed with an escort bed. A storage cabinet is provided under the bed board of the hospital bed, and a foldable escort bed mechanism is arranged in the storage cabinet. In the non-use state, by storing the foldable escort bed mechanism in the storage cabinet and then pushing the storage cabinet under the hospital bed, the occupied space can be reduced. When the escort needs to use the escort bed mechanism to rest, first pull out the storage cabinet from under the hospital bed, and then unfold the foldable escort bed mechanism.

[0004] An existing technology 2 discloses a surgical hospital bed with a built-in escort bed. An escort bed body is arranged under the hospital bed main body, and the escort bed body can move relative to the hospital bed main body, so that the escort bed body can be stored under the hospital bed main body or pulled out from under the hospital bed main body for the escort to rest.

[0005] For the two structures of hospital beds above, the part for the escort to rest is stored under the hospital bed in the non-use state. Currently, most of the hospital beds for patients in hospital wards are equipped with an angle pitching adjustment mechanism, which is arranged under the hospital bed to adjust the angle of the bed board. Therefore, the angle pitching mechanism occupies a considerable part of the space under the hospital bed, making the space under the hospital bed may not be sufficient to accommodate the needs of the escort bed. Therefore, the technical solutions disclosed in the above two patent application documents have high requirements for the space under the hospital bed and poor versatility.

Detailed implementation manners

[0038] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0039] As Figure 1 , Figure 4 And Figure 6 shown, the self-service escort bed includes a wardrobe 1, a bed board A 2, a servo motor 4, a bed board B 5, an external support 7 of the bed board, a connecting rod 9, a support rod A 14, and a support rod B 17. The front and rear ends in the present invention are defined as the two ends in the length direction of the bed board A 2.

[0040] As Figure 6 shown, the wardrobe 1 in the present invention is placed close to the ward wall in the use state, and it includes a back panel 101, a front vertical panel 102, a rear vertical panel 103, and a top panel 104. The heights of the front vertical panel 102 and the rear vertical panel 103 are equal to the height of the back panel 101, and are respectively fixedly connected to both ends of the back panel 101. The left and right ends of the top panel 104 are respectively fixedly connected to the tops of the front vertical panel 102 and the rear vertical panel 103. The side of the top panel 104 close to the back panel 101 is fixedly connected to the top of the back panel 101. The wardrobe 1 in the present invention can be made of wooden boards, and its joints are glued and then fixed with screws. Among them, the back panel 101 is attached to the ward wall in the use state.

[0041] AsFigure 4 and Figure 5 As shown in Figure 5 , the front and rear ends of one side of the bed board A2 are respectively rotatably connected to the front vertical board 102 and the rear vertical board 103 of the wardrobe 1 by a rotating shaft A3, so that the bed board A2 can be turned up and down relative to the wardrobe 1. The installation parts of the rotating shaft A3 on the front vertical board 102 and the rear vertical board 103 are located at the middle parts of the upper and lower parts of the front vertical board 102 and the rear vertical board 103. In the present invention, when the bed board A2 is turned up to a vertical state, the bed board 2 is completely stored in the wardrobe 1. The present invention can use a rotating shaft A3 slightly longer than the bed board A2 to be rotatably connected to the front vertical board 102 and the rear vertical board 103, or two rotating shafts A3 can be fixed at the front and rear ends of the bed board A2 respectively and rotatably connected to the front vertical board 102 and the rear vertical board 103 respectively. In this case, the center lines of the two rotating shafts A3 coincide.

[0042] As Figure 1 and Figure 6 As shown in Figure 6 , the servo motor 4 is installed at the end of the wardrobe 1, and the output shaft of the servo motor 4 is connected to the rotating shaft A3 for driving the bed board A2 to turn relative to the wardrobe 1. In the present invention, when the servo motor 4 drives the bed board A2 to turn up, the bed board A2 can be stored in the wardrobe 1, and when the servo motor 4 drives the bed board A2 to turn down, the bed board A2 can be rotated from the vertical state in the wardrobe 1 to the horizontal state.

[0043] As Figure 1 As shown in Figure 1 , one side of the bed board B5 is rotatably connected to the other side of the bed board A2 by a plurality of hinges 6. As shown in the drawings of the present invention, the bed board B5 and the bed board A2 are rotatably connected by three hinges 6, namely, a front hinge, a middle hinge and a rear hinge. The bed board B5 in the present invention can be turned up and down relative to the bed board A2. When the bed board A2 is turned up, the side of the bed board B5 for connecting with the bed board A2 turns up with the bed board A2, while the side of the bed board B5 away from the bed board A2 remains at a constant height due to the action of gravity. Therefore, the bed board B5 can be stored in the wardrobe 1 together with the bed board A2. When the bed board B5 turns up with the bed board A2, the distance between the bed board B5 and the wardrobe 1 decreases. When the bed board B5 is turned up and stored in the wardrobe 1, the bed board B5 is also in a vertical state. When the bed board B5 turns down with the bed board A2 turning down, it can be used to expand the bed board A2 and the bed board B5 into a horizontal state. In this state, the upper surfaces of the bed board B5 and the bed board A2 are on the same horizontal plane, and at this time, it can be used for the accompanying personnel to lie on it and rest.

[0044] The outer support 7 of the bed board is arranged on the other side of the bed board B5 and is rotatably connected to the bed board B5 by a turning shaft B8. When the bed board B5 turns up and down, the outer support 7 of the bed board moves towards or away from the wall cabinet 1. During the process of the bed board B5 turning up and being stored in the wall cabinet 1, the outer support 7 of the bed board approaches in the direction of the wall cabinet 1, and in the state where the bed board A2 and the bed board B5 are completely stored in the wall cabinet 1, the outer support 7 of the bed board is also stored in the wall cabinet 1. And during the process of the bed board A2 and the bed board B5 moving from being stored in the wall cabinet 1 to being completely unfolded, the outer support 7 of the bed board moves outwards from the wall cabinet 1. When the bed board B5 is in a horizontal state, the outer support 7 of the bed board supports the bed board B5 from the side of the bed board B5 far away from the bed board A2, so that the present invention is in a stable state during use.

[0045] As Figure 2 and Figure 7 shown, the connecting rod 9 in the present invention is in a Z shape. The connecting rod 9 includes a main rod 10 and branch rods 11 located at both ends of the main rod 10 and perpendicular to the main rod 10. At the joints of the two ends of the main rod 10 and the branch rods 11, a turning shaft A12 and a turning shaft B13 are respectively used to rotatably connect to one side of the bed board A2 and the bed board B5 where the hinge 6 is arranged. The branch rod 11 close to the bed board A2 side is located above the main rod 10, while the branch rod 11 close to the bed board B5 side is located below the main rod 10. The main rod 10 in the present invention is always in a horizontal state, while the two branch rods 11 are always in a vertical state. The present invention symmetrically arranges the connecting rod 9, the support rod A14 and the support rod B17 at the front and rear ends of the bed board A2.

[0046] As Figure 4 and Figure 5 shown, one ends of the two support rods A14 in the present invention are respectively rotatably connected to the front vertical plate 102 and the rear vertical plate 103 of the wall cabinet 1 by a turning shaft C15, wherein the turning shaft C15 is directly above the turning shaft A3. The other ends of the two support rods A14 are respectively rotatably connected to the tops of the branch rods 11 close to the bed board A2 side on the two connecting rods 9 by a turning shaft D16. The projections of the turning shaft C15, the turning shaft D16, the turning shaft A3 and the turning shaft A12 on the plane coplanar with the front vertical plate 102 are located at the four vertices of a parallelogram.

[0047] As Figure 3 and Figure 8 shown, one ends of the two support rods B17 in the present invention are respectively rotatably connected to the outer supports 7 at both ends of the bed board B5 by a turning shaft E18. The other ends of the two support rods B17 are respectively rotatably connected to the bottoms of the branch rods 11 close to the bed board B5 side on the two connecting rods 9 by a turning shaft F19. The turning shaft E18 is directly below the turning shaft B8. The projections of the turning shaft E18, the turning shaft F19, the turning shaft B13 and the turning shaft B8 on the plane coplanar with the front vertical plate 102 are located at the four vertices of a parallelogram.

[0048] As Figure 2 shown, at the front and rear ends of the bed board A2 near one side of the bed board B5, there is an installation notch A20 respectively. A gear A21 is arranged in the installation notch A20. The rotating shaft A12 extends into the installation notch A20, and the gear A21 is arranged on the rotating shaft A12. At the front and rear ends of the bed board B5 near one side of the bed board A2, there is an installation notch B22 respectively. The installation notch B22 and the installation notch A20 are distributed facing each other when the bed board A2 and the bed board B5 are both in a horizontal state. A gear B23 is arranged in the installation notch B22. The rotating shaft B13 extends into the installation notch B22, and the gear B23 is arranged on the rotating shaft B13. The gear A21 meshes with the gear B23. When the bed board A2 and the bed board B5 are flipped, the gear A21 and the gear B23 are meshed and driven. Preferably, both the gear A21 and the gear B23 in the present invention adopt incomplete gears. The gear A21 and the gear B23 are only provided with teeth on the facing side, and it is ensured that during the process of the bed board A2 and the bed board B5 being completely stored in the wall cabinet 1 to being unfolded into a horizontal state, the gear A21 and the gear B23 are always meshed with teeth. On the contrary, during the process of the bed board A2 and the bed board B5 being flipped from the unfolded horizontal state to being completely stored in the wall cabinet 1, the gear A21 and the gear B23 are also always meshed with teeth.

[0049] As Figure 3 and Figure 8 shown, the outer support 7 of the bed board in the present invention is two support legs 24 respectively located at the front and rear ends of the bed board B5 away from one side of the bed board A2. At the top of the support leg 24, there is an installation notch C25 penetrating through its left and right sides. One end of the support frame of the bed board B5 away from the bed board A2 extends into the installation notch C25, and the bed board B5 and the support leg 24 are rotationally connected by the rotating shaft B8. In this way, it can be ensured that while the bed board B5 is flipped, the support leg 24 can be flipped relative to the bed board B5. Since there is a support rod B17 connecting the support leg 25 and the connecting rod 9 in the present invention, the support leg 25 in the present invention will only be flipped relative to the bed board B5 when the bed board B5 is flipped. In the case where the bed board B5 is not flipped, the support leg 25 will not be flipped relative to the bed board B5. The outer support 7 of the bed board in the present invention is also provided with rollers 26. The rollers 26 are rotatably arranged at the bottom of the support leg 24, and the axle of the rollers 26 is arranged along the front and rear direction. When the support leg 24 moves towards or away from the wall cabinet 1, the rollers 26 roll relative to the ground.

[0050] As Figure 4 and Figure 6As shown, a floor cabinet 27 is provided below the rotation axis A3 inside the wall cabinet 1 in the present invention. The height of the floor cabinet 27 is less than the height where the rotation axis A3 is located. When the bed board A2 and the bed board B5 are flipped and stored inside the wall cabinet 1, the top surface of the floor cabinet 27 is located below the bed board B5. At this time, the floor cabinet 27 can be opened or closed. The floor cabinet 27 in the present invention is fixed to the back panel 101. A sliding door 28 is provided on the side of the floor cabinet 27 away from the back panel 101. In the present invention, sliding grooves are provided along the front-back direction at both the top and bottom of the floor cabinet 27. The top and bottom ends of the sliding door 28 are both located inside the sliding grooves and can slide inside the sliding grooves. When in use in the present invention, the sliding door 28 is pushed and pulled along the front-back direction to open or close the floor cabinet 27 for taking and placing items inside the floor cabinet 27.

[0051] As Figure 4 and Figure 6 shown, a support storage cavity 29 is left between the two ends of the floor cabinet 27 and the wall cabinet 1 in the present invention. The length of the floor cabinet 27 in the front-back direction is set to be less than the distance between the front vertical plate 102 and the rear vertical plate 103, and the distance between the front end of the floor cabinet 27 and the front vertical plate 102 is equal to the distance between the rear end of the floor cabinet 27 and the rear vertical plate 103, both being slightly greater than the width of the support leg 24 in the front-back direction. When the bed board A2 and the bed board B5 are flipped and completely stored inside the wall cabinet 1, the support legs 24 at the front and rear ends of the bed board B5 are respectively stored inside the support storage cavities 29 on the front and rear sides of the floor cabinet 27.

[0052] The number of servo motors 4 in the present invention is set to two. The two servo motors 4 are respectively detachably installed on the front vertical plate 102 and the rear vertical plate 103 at the two ends of the wall cabinet 1 by bolts, and the output shafts of the two servo motors 4 respectively pass through the front vertical plate 102 and the rear vertical plate 103 and are connected to the rotation axes A3 at both ends of the bed board A2. The two servo motors 4 in the present invention rotate synchronously and in opposite directions, so as to drive the bed board A2 to flip relative to the wall cabinet 1 from both ends of the bed board A2.

[0053] As Figure 1 and Figure 6 shown, in order to facilitate providing services such as charging for the accompanying personnel during use, a socket 30 is provided at the front end and / or the rear end of the wall cabinet 1 in the present invention. A wire conduit can be provided on the wall cabinet 1 for passing the wire connecting the socket 30 and powering the servo motor 4. Preferably, sockets 30 are provided on both the front vertical plate 102 and the rear vertical plate 103 of the wall cabinet 1 in the present invention.
