Description

Technical Field

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

[0002] An escort bed is a public facility provided by a hospital ward for the accompanying personnel of inpatients to rest within a specified time. Limited by the size of the ward space, the escort bed is usually of a folding structure or can be stored under the hospital bed.

[0003] The folding and pull-out type escort bed that is convenient for storage disclosed in the prior art 1 has a sliding plate arranged under the bed board of the hospital bed. The sliding plate is slidably connected to the support plates arranged at the front and rear ends of the hospital bed. Through the relative sliding of the sliding plate and the support plates, the support plates can be pulled out from under the hospital bed in the use state for the accompanying personnel to lie and sleep.

[0004] A hospital bed with an escort bed disclosed in the prior art 2 has a storage cabinet arranged under the bed board. A foldable escort bed mechanism is arranged in the storage cabinet. By storing the foldable escort bed mechanism in the storage cabinet and pushing the storage cabinet under the hospital bed, the space occupied by it can be reduced. When in use, the storage cabinet is pulled out from under the hospital bed, and then the foldable escort bed mechanism is unfolded.

[0005] The escort beds of the above two structures are stored under the hospital bed in the non-use state. Currently, most hospital beds in hospital wards are provided with an angle pitching adjustment mechanism, which is located under the hospital bed and used to adjust the angle of the bed board of the hospital bed. Therefore, it 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 escort bed. Therefore, the above escort beds have high requirements for the space under the hospital bed and poor versatility.

[0006] Prior art 1: The Chinese utility model patent announcement text with the authorization announcement number CN220833359U.

[0007] Prior art 2: The Chinese utility model patent announcement text with the authorization announcement number CN221963944U. Summary of the Invention

[0008] The purpose of the present invention is to provide a shared escort bed to solve the technical defect that the escort bed in the prior art cannot be applied to a hospital bed with an angle pitching adjustment mechanism due to the limitation of the space under the hospital bed.

[0009] To solve the above problems, the technical solution adopted by the present invention is as follows: A shared escort bed, comprising a wall cabinet, a bed board A, a bed board B, an outer support of the bed board, a driving motor, and folding connecting rods. The front and rear ends of one side of the bed board A are rotatably connected to the wall cabinet, enabling the bed board A to rotate up and down relative to the wall cabinet. One side of the bed board B is rotatably connected to the side of the bed board A away from its rotational connection with the wall cabinet by at least two hinges, enabling the bed board B to rotate up and down relative to the bed board A. The front and rear ends of the side of the bed board B away from the wall cabinet are rotatably connected to the outer support of the bed board, enabling the bed board B to rotate up and down relative to the outer support of the bed board. The driving motor is installed inside the wall cabinet and the output shaft of the driving motor is arranged in the vertical direction. The folding connecting rods connect the output shaft of the driving motor and the outer support of the bed board. The folding connecting rods include a connecting rod A and a connecting rod B. One end of the connecting rod A is fixedly connected to the output shaft of the driving motor, the other end of the connecting rod A is rotatably connected to one end of the connecting rod B, and the other end of the connecting rod B is rotatably connected to the outer support of the bed board. The rotation axes of the connecting rod A and the connecting rod B and the connecting rod B and the outer support of the bed board are all in the vertical direction. When the driving motor is started, the user manually lifts the bed board A and / or the bed board B upward from the rotational connection between the bed board A and the bed board B. The driving motor drives the connecting rod A to rotate, and the connecting rod A pulls the connecting rod B to rotate relative to the outer support of the bed board and pulls the outer support of the bed board to move towards the wall cabinet. While the bed board A rotates upward relative to the wall cabinet, the bed board B rotates upward relative to the outer support of the bed board until the bed board A, the bed board B, and the outer support of the bed board are all stored in the wall cabinet. When the driving motor drives the connecting rod A to rotate, and the connecting rod A pushes the outer support of the bed board to move away from the wall cabinet through the connecting rod B, the bed board A rotates downward relative to the wall cabinet, and the bed board B rotates downward relative to the outer support of the bed board until the bed board A and the bed board B are both in a horizontal state.

[0010] When the present invention is in use, it is placed closely against the wall of the ward. In the state of being stored and folded, the bed board A and the bed board B are rotated and stored in the wall cabinet, reducing the occupied space. In the state of use, the bed board A and the bed board B are rotated to a horizontal state for the escort personnel in the ward to lie down and rest. The bed board A and the bed board B in the present invention rotate up and down when being stored and unfolded, so the required height increases, while the thickness requirement is relatively low. Compared with the prior art of being stored under the hospital bed, the present invention does not need to consider the structure of the hospital bed. Since the present invention is not stored under the hospital bed when in use, it is not affected by the space occupied by the flipping structure of the hospital bed and is suitable for use in wards with different hospital beds, having good versatility.

[0011] As a further improvement of the present invention, the number of drive motors is two, and the two drive motors are respectively located at the front and rear ends inside the wall cabinet. The number of folding linkages is two. One folding linkage connects the drive motor at the front end of the wall cabinet and the front end of the outer support of the bed board, and the other folding linkage connects the drive motor at the rear end of the wall cabinet and the rear end of the outer support of the bed board. The output shafts of the two drive motors rotate simultaneously and in opposite directions, respectively driving the flipping of the bed board A and the bed board B from the front and rear ends of the outer support of the bed board. In the present invention, two drive motors are provided to drive the flipping of the bed board A and the bed board B from the front and rear ends of the outer support of the bed board, and the force is more uniform when the present invention is folded and unfolded.

[0012] As a further improvement of the present invention, it further includes an inner support of the bed board. The inner support of the bed board is fixed inside the wall cabinet. The front and rear ends of the bed board A are respectively rotatably connected to the inner support of the bed board, and both drive motors are installed on the inner support of the bed board. In the present invention, the inner support of the bed board is provided to facilitate the flipping of the bed board A during use.

[0013] As a further improvement of the present invention, both the inner support of the bed board and the outer support of the bed board include two front and rear bed legs and a cross bar connecting the two front and rear bed legs. One end of each of the two linkages B is respectively rotatably connected to the front and rear ends of the upper cross bar of the outer support of the bed board. The two drive motors are respectively installed on the two bed legs of the inner support of the bed board. Notches are provided at the tops of the bed legs of the inner support of the bed board and the outer support of the bed board. The front and rear ends of the bed board A and the bed board B are respectively rotatably connected to the bed legs in the notches. In the present invention, the overall strength and stability of the inner support of the bed board and the outer support of the bed board are better, and since notches are provided on the bed legs, while facilitating the installation of the bed board A and the bed board B, the bed legs will not interfere with the flipping of the bed board A and the bed board B.

[0014] As a further improvement of the present invention, rollers are provided at the bottoms of the two bed legs of the outer support of the bed board, and the rollers rotate when the outer support of the bed board moves relative to the wall cabinet. In the present invention, rollers are provided on the bed legs of the outer support of the bed board, which can reduce the friction between the rollers and the ground, making the folding, storage and unfolding of the present invention more energy-saving.

[0015] As a further improvement of the present invention, a groove is provided on one side of the wall cabinet away from the bed board A, and a power cord for connecting to a socket on the wall is arranged therein, and the power cord supplies power to the drive motor. In the present invention, by providing a groove on the wall cabinet, space can be provided for the power cord and the plug at the end of the power cord to avoid the power cord, the plug and the socket on the hospital wall, so that the wall cabinet can better fit the wall of the hospital ward.

[0016] As a further improvement of the present invention, an embedded speaker and a power socket are provided on the wall cabinet, and both the embedded speaker and the power socket are connected to the power cord. The embedded speaker in the present invention can play music and the like through a connected playback device for the entertainment of patients or accompanying personnel, and the power socket can provide power support for the accompanying personnel.

[0017] As a further improvement of the present invention, a magnetic lock is provided at the lower part of the front end and / or the rear end of the wall cabinet, and a lock frame is provided at the lower part of the front end and / or the rear end of the outer support of the bed board. When the bed board A, the bed board B and the outer support of the bed board are simultaneously stored in the wall cabinet, the magnetic lock adsorbs the lock frame. By providing the magnetic lock, in the state where the bed board A, the bed board B and the outer support of the bed board are in the stored state, the outer support of the bed board is adsorbed to prevent the present invention from being unfolded due to a malfunction or a misoperation during a non-specified use time.

[0018] As a further improvement of the present invention, rubber pads are provided on one side of the bed board A and / or the bed board B where they are rotatably connected. When the bed board A and the bed board B are flipped to the horizontal state, the rubber pads are located between the bed board A and the bed board B. By providing the rubber pads on the bed board A and / or the bed board B, when the bed board A and the bed board B are flipped to the horizontal state, the collision between the two can be effectively avoided, thereby reducing the generation of excessive noise.

[0019] As a further improvement of the present invention, it further includes two vertical blocking rods, which are fixed to the front and rear ends inside the wall cabinet, and the vertical blocking rods and the outer support of the bed board are respectively located on both sides of the inner support of the bed board. By providing the vertical blocking rods on the inner side of the inner support of the bed board, the distance between the bed board A and the inner surface of the wall cabinet can be increased, so that the bed board A can be in a vertical state when it is in the stored state, and the bed board B and the outer support of the bed board can be prevented from being outside the wall cabinet.

[0029] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] As Figures 1 to 7 The shared escort bed shown includes a wardrobe 1, a bed board A 2, a bed board B 3, an outer support 5 of the bed board, a driving motor 6, and a folding connecting rod 7. The front and rear ends of one side of the bed board A 2 are rotatably connected to the wardrobe 1, so that the bed board A 2 can be turned up and down relative to the wardrobe 1. When the bed board A 2 is turned up to the vertical state, it can be stored in the wardrobe 1. One side of the bed board B 3 is rotatably connected to the side of the bed board A 2 away from its rotatable connection with the wardrobe 1 by at least two hinges 4, so that the bed board B 3 can be turned up and down relative to the bed board A 2. In the present invention, three hinges 4 are used to rotatably connect the bed board B 3 and the bed board A 2, and the three hinges 4 are arranged at equal intervals in the front-rear direction. When the bed board A 2 is turned up, the side of the bed board B 3 away from the bed board A 2 is turned down relative to the bed board A 2. When the bed board B 3 and the bed board A 2 are turned to the vertical state, both the bed board A 2 and the bed board B 3 are stored in the wardrobe 1. The bed board A 2 and the bed board B 3 in the present invention both include a metal frame and a mattress. The bed board A 2 and the bed board B 3 themselves are prior art and will not be described in detail in the present invention.

[0031] As Figures 1 to 3As shown in the figure, both the front and rear ends of the bed board B3 away from the wardrobe 1 in the present invention are rotatably connected to the outer support 5 of the bed board. The bed board B3 can be turned up and down relative to the outer support 5 of the bed board. Since the bed board A2 and the outer support 5 of the bed board are located on both sides of the bed board B3 respectively, when the bed board B3 turns down relative to the bed board A2, the bed board B3 turns up relative to the outer support 5 of the bed board. The driving motor 6 is installed in the wardrobe 1 and the output shaft of the driving motor 6 is arranged in the vertical direction. The folding connecting rod 7 connects the output shaft of the driving motor 6 and the outer support 5 of the bed board. The folding connecting rod 7 includes a connecting rod A8 and a connecting rod B9. Both the connecting rod A8 and the connecting rod B9 are in a horizontal state. One end of the connecting rod A8 is fixedly connected to the output shaft of the driving motor 6. The driving motor 6 directly drives the connecting rod A8 to rotate in the horizontal plane. The other end of the connecting rod A8 is rotatably connected to one end of the connecting rod B9. The other end of the connecting rod B9 is rotatably connected to the outer support 5 of the bed board. The rotation axes of the connecting rod A8 and the connecting rod B9 and the connecting rod B9 and the outer support 5 of the bed board are all in the vertical direction. Since both ends of the connecting rod B9 are rotatably connected to the connecting rod A8 and the outer support 5 of the bed board respectively, when the connecting rod A8 rotates, it can drive the connecting rod B9 to rotate. When the connecting rod B9 rotates, it can pull the outer support 5 of the bed board to move horizontally towards the wardrobe 1 or push the outer support 5 of the bed board to move horizontally away from the wardrobe 1. In the present invention, the driving motor 6 drives the folding connecting rod 7 to rotate, providing power for the movement of the outer support 5 of the bed board, and the movement of the outer support 5 of the bed board provides power for the folding or unfolding of the bed board A2 and the bed board B3.

[0032] Since when the bed board A2 and the bed board B3 are in a horizontal state in the present invention, the horizontal movement of the outer support 5 of the bed board cannot push the bed board A2 and the bed board B3 to turn over, when the bed board A2 and the bed board B3 are folded, it is necessary to manually lift the bed board A2 and / or the bed board B3 upwards. When a certain angle is formed between the bed board A2 and the bed board B3, the bed board A2 and / or the bed board B3 can be released. The driving motor 6 drives the outer support 5 of the bed board to move through the folding connecting rod 7, so that the bed board A2 and the bed board B3 continue to turn over and fold.

[0033] The folding process of the present invention is as follows: while starting the driving motor 6, manually lift the bed board A2 and / or the bed board B3 upwards from the rotating connection between the bed board A2 and the bed board B3. The driving motor 6 drives the connecting rod A8 to rotate. When a certain angle (not 180°) is formed between the bed board A2 and the bed board B3, the bed board A2 and / or the bed board B3 can be released. At this time, the connecting rod A8 pulls the connecting rod B9 to rotate relative to the outer support 5 of the bed board, and pulls the outer support 5 of the bed board to move towards the wardrobe 1. At this time, the bed board A2 turns up relative to the wardrobe 1, and the bed board B3 turns up relative to the outer support 5 of the bed board. The angle between the bed board A2 and the bed board B3 gradually decreases until the bed board A2, the bed board B3 and the outer support 5 of the bed board are all stored in the wardrobe 1 at the same time. The structure after folding and storage is as Figures 4 to 7As shown, during the folding process of the bed board A2 and the bed board B3, the outer support 5 of the bed board always remains in contact with the ground. That is, the outer support 5 of the bed board in the present invention only moves in the horizontal direction, without rotating or generating displacement in the vertical direction.

[0034] The process of the present invention being unfolded into the use state is as follows: The driving motor 6 drives the link A8 to rotate away from the wall cabinet 1. While the link A8 pushes the outer support 5 of the bed board to move away from the wall cabinet 1 through the link B9, the bed board B3 flips downward relative to the outer support 5 of the bed board. The flipping of the bed board B3 in turn pulls the bed board A2 to flip downward relative to the wall cabinet 1. The included angle between the bed board A2 and the bed board B3 gradually increases until both the bed board A2 and the bed board B3 are in a horizontal state. During the process of the present invention being unfolded to the use state, the outer support 5 of the bed board also only moves in the horizontal direction, without rotating or generating displacement in the vertical direction.

[0035] The number of driving motors 6 in the present invention is optimally set to two. The two driving motors 6 are respectively located at the front and rear ends inside the wall cabinet 1. The number of folding links 7 is also two. One folding link 7 connects the output shaft of the driving motor 6 at the front end of the wall cabinet 1 and the front end of the outer support 5 of the bed board, and the other folding link 7 connects the output shaft of the driving motor 6 at the rear end of the wall cabinet 1 and the rear end of the outer support 5 of the bed board. The output shafts of the two driving motors 6 rotate simultaneously and in opposite directions, driving the outer support 5 of the bed board to move relative to the wall cabinet 1 from the front and rear ends respectively. The front and rear ends of the outer support 5 of the bed board drive the bed board A2 and the bed board B3 to flip, so that the forces at both ends are evenly distributed when the bed board A2 and the bed board B3 flip.

[0036] As Figure 2 and Figure 3 shown, the present invention is provided with an inner support 10 of the bed board. The inner support 10 of the bed board is fixed inside the wall cabinet 1. The front and rear ends of the bed board A2 are respectively rotatably connected to the inner support 10 of the bed board. Both driving motors 6 are detachably mounted on the inner support 10 of the bed board by a plurality of bolts. The inner support 10 of the bed board and the outer support 5 of the bed board in the present invention both include two front and rear bed legs 11 and a cross bar 12 connecting the two front and rear bed legs 11. The cross bar 12 is fixedly connected to the middle parts on the opposite sides of the two bed legs 11. One end of each of the two links B9 is respectively rotatably connected to the front and rear ends of the cross bar 12 on the outer support 5 of the bed board. The present invention is provided with a connecting shaft at each of the front and rear ends of the cross bar 12. The connecting shaft passes through the link B9, and the link B9 can rotate relative to the connecting shaft. The two driving motors 6 are respectively mounted on the opposite sides of the two bed legs 11 of the inner support 10 of the bed board. The cross-sectional shapes of the bed legs 11 and the cross bar 12 in the present invention are both rectangular, so as to facilitate the installation of the driving motor 6 and the connecting shaft.

[0037] As Figure 2 and Figure 3As shown, notches 13 are provided at the tops of the legs 11 of the inner support 10 and the outer support 5 of the bed board of the present invention. The front and rear ends of the bed board A2 and the bed board B3 are respectively rotatably connected to the legs 11 within the notches 13, and the depth of the notches 13 above and below is set to the minimum requirement that does not affect the flipping of the bed board A2 and the bed board B3. At the bottoms of the two legs 11 of the outer support 5 of the bed board of the present invention, rollers 14 are provided. The mounting shafts of the rollers 14 are arranged in the front-rear direction. When the outer support 5 of the bed board moves relative to the wardrobe 1, the rollers 14 rotate to reduce the friction between the outer support 5 of the bed board and the ground.

[0038] As Figure 3 shown, on the side of the wardrobe 1 away from the bed board A2 of the present invention, a groove 15 is provided. A power cord 16 for connecting to a socket on the wall is arranged within the groove 15. The power cord 16 is connected to the drive motor 6 to supply power for the operation of the drive motor 6. Since the power cord is within the groove 15, when the present invention is in use, the wardrobe 1 can fit better with the wall of the ward. An embedded speaker 17 and a power socket 18 are provided on the wardrobe 1. Both the embedded speaker 17 and the power socket 18 are connected to the power cord 16. The embedded speaker 17 of the present invention is arranged on the lower side of the wardrobe 1 away from the bed board A2, while the power socket 18 is arranged on the upper side of the wardrobe 1 away from the bed board A2. The power socket 18 can provide electrical energy for the accompanying personnel, such as charging a mobile phone, etc. The embedded speaker 17 can be connected to a music or video player during use for the patient or the accompanying personnel to relax. The embedded speaker 17 and the power socket 18 in the present invention can be used independently within the time limit for the deployment of the bed board A2 and the bed board B3 specified by the hospital, that is, the use of the embedded speaker 17 and the power socket 18 is not restricted by the time specified by the hospital.

[0039] As Figures 1 to 7 shown, magnetic locks 19 are provided at the lower part of the front end and / or the rear end of the wardrobe 1, and a lock frame (not shown in the figure) is provided at the lower part of the front end and / or the rear end of the outer support 5 of the bed board. In the state where the bed board A2, the bed board B3, and the outer support 5 of the bed board are simultaneously stored in the wardrobe 1, the magnetic locks 19 adsorb the lock frame to prevent the bed board A2, the bed board B3, and the outer support 5 of the bed board from automatically unfolding due to a malfunction during non-specified time.

[0040] As Figure 4 and Figure 5 shown, rubber pads 20 are provided on the sides where the bed board A2 and / or the bed board B3 are rotatably connected. Rubber pads 20 are fixed on both the bed board A2 and the bed board B3. When the bed board A2 and the bed board B3 are flipped to the horizontal state, the rubber pads 20 on the bed board A2 and the bed board B3 are located between the bed board A2 and the bed board B3, and the rubber pad 20 on the bed board A2 and the rubber pad 20 on the bed board B3 are in contact with each other to avoid noise generated by collision when the bed board A2 and the bed board B3 are unfolded.

[0041] As Figure 3 shown, in order to facilitate the storage of the bed board A2, the bed board B3 and the outer support 5 of the bed board in the wall cabinet 1, the present invention is provided with two vertical blocking rods 21, which are fixed at the front and rear ends inside the wall cabinet 1, and the vertical blocking rods 21 and the outer support 5 of the bed board are respectively located on both sides of the inner support 10 of the bed board, so as to increase the distance between the bed board A2 and the inner surface of the wall cabinet 1 and ensure that the bed board A2 can be in a vertical state in the storage state.

[0042] Parts not specifically described in the above specification are all prior arts or can be realized by prior arts. Moreover, the specific implementation cases described in the present invention are only the preferred implementation cases of the present invention, and are not used to limit the implementation scope of the present invention.
