[0002] There are beds that are provided with detachable side guards to close the gaps between the headboard and / or footboard and the side rails. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-061524 A Summary of the Invention [Problem to be solved by the invention]

[0004] There are beds whose longitudinal length can be changed. In addition, the bed has a fence on the side of the bed to prevent the user from falling off the bed. For example, even if there is no gap between the headboard and the fence when the length is a first length, a gap may occur between the headboard and the fence when the length is a second length longer than the first length. When a gap occurs between the headboard and the fence, if the user falls on the bed, the user's body, for example, the neck, may be caught, so the gap needs to be guarded.

[0005] If the gap between the board and the fence is guarded by a removable side guard, the side guard is a separate component, which leads to high costs. In addition, the cost can make people hesitate to install side guards. Furthermore, the work of attaching the side guards to the bed is time-consuming. In addition, there are cases where people forget to attach the side guards, or where safety cannot be ensured until the side guards are attached.

[0006] An object of the embodiments of the present invention is to provide a board and bed that are cost-effective and have high safety. [Means for solving the problem]

[0007] According to an embodiment, a board used in a bed that changes between a first position and a second position that is longer in the front-to-rear direction than the first position includes a guard having a protruding portion that protrudes from the board toward a fence provided on the bed so as to fill a gap between the board and the fence. The guard fills the gap formed between the board and the fence in the first position and the gap formed between the board and the fence in the second position.

[0008] According to an embodiment, the bed includes a bed body that changes between a first position and a second position that is longer in the front-rear direction than the first position, a fence support part provided on the bed body, a fence that is detachably provided on the fence support part, and a board that is provided along a direction intersecting the front-rear direction. The board includes a guard having a protruding part that protrudes from the board toward the fence so as to fill a gap between the board and the fence, and the guard fills a gap formed between the board and the fence in the first position and a gap formed between the board and the fence in the second position.

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc. are not necessarily the same as those in reality. Even when the same part is shown, the dimensions and ratios of each part may be different depending on the drawing. In this specification and each drawing, elements similar to those described above with reference to the previous drawings are given the same reference numerals and detailed descriptions thereof will be omitted as appropriate.

[0012] (First embodiment) Fig. 1 is a perspective view showing an example of the appearance of bed 1 in a first position. Fig. 2 is a top view showing an example of the upper surface of bed 1 in a first position. Fig. 3 is a side view showing an example of the side surface of bed 1 in a first position.

[0013] Fig. 4 is a perspective view showing an example of the appearance of bed 1 in the second position. Fig. 5 is a top view showing an example of the upper surface of bed 1 in the second position. Fig. 6 is a side view showing an example of the side surface of bed 1 in the second position.

[0014] As shown in Figs. 1 to 6, the bed 1 includes a bed body 10, a headboard 11, a footboard 12, and rails 13A to 13D. Guards 20A and 20B are provided on the upper sides of both ends of the headboard 11, and guards 20C and 20D are provided on the upper sides of both ends of the footboard 12. The bed 1 will be described as being an electrically-operated bed, but it may be a non-electrical bed. The first position and second position aspects of the bed 1 will be described in detail later.

[0015] Bed 1 is used with the user's head positioned on the headboard 11 side and the user's feet positioned on the footboard 12 side. In the following description, the direction from the user's head to the feet is defined as the front-rear direction, the direction intersecting the front-rear direction is defined as the left-right direction, and the direction perpendicular to the front-rear direction and the left-right direction is defined as the up-down direction.

[0016] Fig. 7 is a perspective view showing an example of the bed body 10. As shown in Fig. 7, the bed body 10 includes a head side frame 14A, a foot side frame 14B, and a side frame 14. The head side frame 14A includes board attachment parts 15A and 15B, and the foot side frame 14B includes board attachment parts 15C and 15D.

[0017] The bed body 10 has a rectangular shape with the longitudinal direction in the front-rear direction in top view. The headboard 11 is attached to the board attachment parts 15A, 15B of the head side frame 14A. The footboard 12 is attached to the board attachment parts 15C, 15D of the foot side frame 14B. As shown in Figs. 1 to 6, the headboard 11 and the footboard 12 are attached to the bed body 10 along the height direction. As shown in Figs. 3 and 6, the first height of the footboard 12 is lower than the second height of the headboard 11 by a distance D1. By lowering the first height of the footboard 12 in this way, for example, a television placed on the footboard 12 side becomes easier for the user of the bed 1 to see, and the user can easily see the faces of family members, visitors, nurses, care staff, etc. and can easily talk to them.

[0018] The side of the bed body 10 is provided with fence support parts 10A to 10D. On the left side of the bed body 10, the fence support part 10A is attached to the side frame 14 so that the fence support part 10A is on the front side and the fence support part 10B is on the rear side. On the right side of the bed body 10, the fence support part 10C is attached to the side frame 14 so that the fence support part 10C is on the front side and the fence support part 10D is on the rear side. In this embodiment, the fence support parts 10A to 10D each have two recesses (not shown) formed on the upper surface side and spaced apart in the front-rear direction. On the other hand, the fences 13A to 13D each have a protrusion (not shown) formed to correspond to the two recesses. The fences 13A to 13D are attached to the bed body 10 by inserting the protrusions of the fences 13A to 13D into the recesses of the fence support parts 10A to 10D. Also, the fences 13A to 13D can be easily removed from the fence support parts 10A to 10D by lifting them upwards.

[0019] The bed 1 has a bed body 10 surrounded by a headboard 11, a footboard 12, and railings 13A to 13D. This prevents a user using the bed 1 from falling off the bed 1.

[0020] Next, the first position and the second position of the bed 1 will be described. First, the structure of the bed body 10 will be described with reference to FIG.

[0021] The board attachment parts 15A, 15B are provided so as to be slidable in the front-rear direction relative to the head side frame 14A. The projection dimension of the board attachment parts 15A, 15B from the head side frame 14A is adjusted according to the first position and the second position of the first adjustment member 30. The first adjustment member 30 may be configured to be capable of causing the board attachment parts 15A, 15B to project from the head side frame 14A.

[0022] The board attachment parts 15C, 15D are provided so as to be slidable in the front-rear direction relative to the foot side frame 14B. The projection dimensions of the board attachment parts 15C, 15D from the foot side frame 14A are adjusted according to the first and second positions of the second adjustment member 50. The second adjustment member 50 may be configured to allow the board attachment parts 15C, 15D to project from the foot side frame 14B.

[0023] 1 to 3, the first position of the bed 1 is a state in which both the head side and the foot side of the bed body 10 are in the first position. That is, the board attachment parts 15A and 15B do not protrude from the head side frame 14A, and the board attachment parts 15C and 15D do not protrude from the foot side frame 14B.

[0024] 4 to 6 show the second position of the bed 1 in which both the head side and the foot side are in the second position, that is, the board attachment parts 15A and 15B protrude from the head side frame 14A, and the board attachment parts 15C and 15D protrude from the foot side frame 14B.

[0025] In this way, by changing the state of the bed 1 in the first position and the state of the bed 1 in the second position, the length dimension in the front-rear direction of the bed 1 can be easily changed. Note that the length dimension in the front-rear direction of the bed 1 may be changed by making the head-side board attachment parts 15A, 15B protrude and making the foot-side board attachment parts 15C, 15D not protrude, or the length dimension in the front-rear direction of the bed 1 may be changed by making the head-side board attachment parts 15A, 15B not protrude and making the foot-side board attachment parts 15C, 15D protrude.

[0026] Next, the guards 20A to 20D will be described. In this embodiment, the guard 20A provided on the left side of the headboard 11 in top view will be described as an example. The guard 20B provided on the right side of the headboard 11 is the same as the guard 20A except that it has a symmetrical configuration. The guards 20C and 20D provided on the footboard 12 are the same as the guards 20B and 20A provided on the headboard 11, respectively. In other words, the guards 20A and 20D located diagonally on the bed 1 have the same shape, and the guards 20B and 20C have the same shape.

[0027] Fig. 8 is a perspective view showing an example of the headboard 11. Fig. 9 is a perspective view showing a guard 20A provided on the headboard 11 of Fig. 8 from the inside. Fig. 10 is a perspective view showing an example of the inside of the guard 20A.

[0028] As shown in Figs. 8 to 10, the guard 20A provided on the headboard 11 is composed of a first member 20A1, a second member 20A2, and a third member 20A3. The third member 20A3 is an L-shaped metal fitting when viewed from above. A first surface of the third member 20A3 is fixed to the headboard 11 by, for example, bolts V1 and V2. A second surface of the third member 20A3 is used to support the first member 20A1 from the inside.

[0029] The first member 20A1 and the second member 20A2 are members that cover the third member 20A3, and are formed of, for example, resin. The first member 20A1 covers the second surface of the third member 20A3, the upper side of the end of the headboard 11, and a part of the side surface from the outside of the bed 1. A fitting portion is formed in the inner portion of the first member 20A1. The second member 20A2 covers the first surface of the third member 20A3 and the inside of the first member 20A1. The second member 20A2 is fitted into and fixed to the fitting portion of the first member 20A1. In a side view, the lower side of the guard 20A includes a reverse tapered portion T.

[0030] Next, the positional relationship between the guards 20A to 20D and the fences 13A to 13D will be described. In this embodiment, the positional relationship between the guard 20A provided on the left side of the headboard 11 in top view and the fence 13A will be described as an example.

[0031] Fig. 11 is a side view showing an example of the positional relationship between the guard 20A and the fence 13A when the bed 1 is in a first position. Fig. 12 is a top view of Fig. 11. Fig. 13 is a side view showing an example of the positional relationship between the guard 20A and the fence 13A when the bed 1 is in a second position. Fig. 14 is a top view of Fig. 13.

[0032] 11, when the bed 1 is in the first position, a part of the fence 13A is located to the left (the front side in the figure) of the protruding part P1 of the first member 20A1 that protrudes inwardly of the bed 1 in the front-rear direction. In other words, in a side view, the protruding part P1 of the guard 20A and a part of the fence 13A overlap each other. Therefore, in the first position, the guard 20A prevents a gap from being formed between the headboard 11 and the fence 13A.

[0033] 12, when the bed 1 is in the first position, the guard 20A provided on the headboard 11 is offset in the left-right direction from the side surface of the railing 13A toward the inside of the bed 1. However, the offset distance D2 is small.

[0034] In this way, when the bed 1 is in the first position, no gaps that could trap a user are created between the headboard 11 and the railing 13A in the front-rear and left-right directions.

[0035] Also, as shown in Fig. 13, when the bed 1 is in the second position, the tip of the protruding portion P1 of the first member 20A1 protruding from the guard 20A toward the inside of the bed 1 and the tip of the fence 13A are at approximately the same position in the front-to-rear direction. Therefore, the guard 20A does not form a gap between the headboard 11 and the fence 13A. Note that the tip of the protruding portion P1 of the first member 20A1 and the tip of the fence 13A may partially overlap. When the tip of the protruding portion P1 and the tip of the fence 13A overlap in the second position, the overlapping portion in the front-to-rear direction is smaller than in the first position.

[0036] As shown in Fig. 14, when the bed 1 is in the first position and the second position, the guard 20A provided on the headboard 11 is offset in the left-right direction from the side surface of the fence 13A toward the inside of the bed 1. Since the protruding portion P1 of the guard 20A is offset from the fence 13A in this way, when the bed 1 is in the first position, even if the protruding portion P1 of the guard 20A overlaps with a part of the fence 13A in a side view, the protruding portion P1 of the guard 20A does not get in the way. Furthermore, since the protruding portion P1 is offset, it is possible to change the bed 1 from the first position to the second position by protruding the head-side board attachment parts 15A, 15B and increasing the length dimension of the bed body 10.

[0037] In this way, when the bed 1 is in the second position, as when it is in the first position, there are no gaps between the headboard 11 and the railing 13A in the front-to-back and left-to-right directions that could trap a user.

[0038] Note that with reference to Figures 11 to 14, an example of the positional relationship between guard 20A provided at the left end of headboard 11 and fence 13A has been explained, but the positional relationship between guard 20B provided at the right end of headboard 11 and fence 13C, and the positional relationship between guards 20C, 20D provided at both ends of footboard 12 and fences 13B, 13D are also similar.

[0039] As described above, in the bed 1, the guards 20A to 20D are provided on the headboard 11 and the footboard 12, so that the guards 20A to 20D can be included in the headboard 11 and the footboard 12. Therefore, there is no need to attach a guard member for guarding the gap, and the cost of introducing the guard member can be reduced. In addition, since the guards are provided on the headboard 11 and the footboard 12, the effort of attaching the guard member is eliminated, and the situation of forgetting to attach the guard member can be avoided. Therefore, for example, when a user falls on the bed 1, it is possible to prevent the user's body, for example, the neck, from being caught in the gap between the headboard 11 and the footboard 12 and the rails 13A to 13D. Therefore, the bed 1 can reduce costs and increase safety.

[0040] In addition, in the left-right direction, the positions of the guards 20A-20D are offset toward the inside of the bed 1 from the positions of the fences 13A-13D, respectively. This prevents the protruding parts P1 of the guards 20A-20D from colliding with the side surfaces of the fences 13A-13D, preventing the length dimension of the bed 1 in the front-rear direction from being unable to be changed.

[0041] Furthermore, the guards 20A-20D include a tapered portion T formed in a reverse tapered shape on the lower side. Therefore, for example, when the bed 1 is in the first position, when an operator removes a futon or sheets laid on the bed body 10, the ends of the futon or sheets will not get caught on the guards 20A-20D. This reduces the burden on the operator when changing the futon or sheets.

[0042] Furthermore, the upper sides of the guards 20A-20D include straight sections, for example, as shown in Figures 11 and 13. This allows the guards 20A-20D to be used as handrails when the user of the bed 1 is near the bed. By smoothing the corners of the straight sections into curved shapes, the guards can be shaped to provide an easy-to-hold grip when turning over in bed, etc.

[0043] Second embodiment The second embodiment differs from the first embodiment in that the guards 20A to 20D are configured to include detection devices. Therefore, the differences will be described in detail. Also, the same components as those in the first embodiment are given the same reference numerals, and detailed descriptions thereof will be omitted. The bed 1A of this embodiment is an electric bed.

[0044] FIG. 15 is a diagram showing a part of the control configuration of the bed 1A. 15, the bed 1A includes a control unit 101, a communication unit 102, and detection units 111 to 114. Note that, in this embodiment, a case will be described in which four detection units 111 to 114 are provided in the bed 1A, but the bed 1A may be configured to be provided with a detection unit selected from the four detection units 111 to 114, or may be configured to add other detection units to the selected detection units.

[0045] The control unit 101 executes processing to control the operation of the back bottom, knee bottom, frame, etc. of the bed 1, as well as outputting the detection results of the detection units 111-114. The communication unit 102 is an interface for communicating with an operation device that issues operational instructions to the bed 1A, an information processing device communicatively connected to the bed 1A, etc. The information processing device may be a management server that manages information of the hospital, etc. in which the bed 1A is installed, or a smartphone carried by the care staff who cares for the user.

[0046] The detection unit 111 is, for example, a pressure sensor. In this embodiment, the detection unit 111 is disposed on the upper portion of each of the guards 20A to 20D. For example, a pressure sensor may be disposed on the upper portion of the guards 20A to 20D and the pressure sensor may be covered. This allows the detection unit 111 to detect that the guards 20A to 20D are gripped. The detection result is transmitted to the control unit 101.

[0047] The detection unit 112 is, for example, an infrared sensor. In this embodiment, the detection unit 112 is disposed inside the guards 20A-20D so as to irradiate infrared rays in a direction from each of the guards 20A-20D toward the inside of the bed 1A, that is, in the front-rear direction. This allows the detection unit 112 to detect whether or not a user has passed over the bed 1A. The detection result is transmitted to the control unit 101.

[0048] The detection unit 113 is, for example, an infrared sensor. In this embodiment, the detection unit 113 is disposed on each of the guards 20A to 20D so as to irradiate infrared rays in the direction in which the fences 13A to 13D are disposed. This allows the detection unit 113 to detect whether the fences 13A to 13D are attached to or detached from the bed 1A. The detection result is transmitted to the control unit 101.

[0049] The detection unit 114 is, for example, an infrared sensor. In this embodiment, the detection unit 114 is disposed on each of the guards 20A to 20D so as to irradiate infrared rays slightly outward from the side of the bed 1A. This allows the detection unit 114 to detect whether or not the comforter has fallen off the bed 1A. The detection result is transmitted to the control unit 101.

[0050] The positions of the guards 20A-20D provided above both ends of the headboard 11 and the footboard 12 are positions that make it possible to distinguish between the area inside the bed 1A and the area outside the bed 1A. Therefore, by providing the guards 20A-20D with detectors 111-114 and acquiring the detection results, it becomes possible to detect the state of the bed 1A, including the user.

[0051] In addition, by transmitting the detection results from the control unit 101 to an information processing device, for example, a care staff member can use the information processing device to grasp the status of the bed 1A, including the user using the bed 1A, even if he or she is not near the bed 1A.

[0052] The above describes the embodiment of the present invention with reference to specific examples. However, the present invention is not limited to these specific examples. For example, the specific configurations of each element, such as the guard, the detection unit included in the guard, and the members included in the bed, are included in the scope of the present invention as long as a person skilled in the art can implement the present invention in a similar manner and obtain similar effects by appropriately selecting them from the known range.

[0053] Any combination of two or more elements of each embodiment, within the scope of technical feasibility, is also included within the scope of the present invention as long as it includes the gist of the present invention.

[0054] In addition, all boards and beds that can be implemented by a person skilled in the art by appropriately modifying the design based on the guard described above as an embodiment of the present invention also fall within the scope of the present invention as long as they include the gist of the present invention.

[0055] In addition, within the scope of the concept of the present invention, a person skilled in the art may think of various modifications and alterations, and it will be understood that these modifications and alterations also fall within the scope of the present invention.
