Summary of the Invention

Problems to be Solved by the Invention

[0004] However, since the drive mechanism of the conventional electric bed is an integral type, the overall weight is quite large, so it is difficult to carry it into and install it in a living room, especially for living rooms on the second floor or higher.

Effects of the Invention

[0013] According to the present invention, the base, the first frame with a first support unit equipped with a first drive unit, and the second frame with a second support unit equipped with a second drive unit are separate components. Therefore, they can be easily transported to the installation location, even on the second floor, and after transport, the first and second frames can be assembled separately to the base at the installation location. Furthermore, when the electric bed is no longer needed, it can be easily disassembled into its base, first frame, and second frame, making removal from the installation site straightforward. Furthermore, since this entire process can be performed by a single worker, labor costs can be reduced.

[0014] Furthermore, even if a lifting platform equipped with a lifting drive unit is provided on the base, these can be easily assembled after being transported separately from the first frame and the second frame, and can be easily transported separately when it is time for disposal.

[0015] Furthermore, according to the present invention, at the installation site, the first frame and the second frame are connected on the base via connecting members, and the user's head side of the first frame is fixed to the base via a first fixing part, and the user's toes side of the second frame is fixed to the base via a second fixing part. However, the central part of the entire frame, including the connecting members, is not fixed but is supported from below by a support plate. For example, even if the central part of the entire frame, i.e., the side of the second frame on the first frame and the side of the first frame on the second frame, is displaced or distorted due to tilting of the first support part or the second support part, that part is not fixed to the base and is therefore prevented from being subjected to particularly large loads. If the central part of the entire frame, that is, the side of the second frame on the first frame and the side of the first frame on the second frame, is fixed to the base, the first support part and the second support part may tilt, or the movement of the user may place a large load on the central part of the entire frame, which may cause that part to break. These effects are the same even when a lifting platform with a lifting drive unit attached to the base is provided.

[0016] Furthermore, according to the present invention, the connecting member is inserted into the space formed at the ends of the left and right vertical frames constituting the first frame and the space formed at the ends of the left and right vertical frames constituting the second frame that are opposite to it, and is fixed with fastening members such as bolts from at least the outside bottom and side of the vertical frames, so the connecting strength is great and it is stable even when the first support part or the second support part tilts or when the user moves.

[0017] Furthermore, according to the present invention, the support plate simultaneously supports from below both the horizontal frame that spans the left and right vertical frames of the first frame and the horizontal frame that spans the left and right vertical frames of the second frame. Therefore, even if there is some misalignment, it is reliably supported from below. [Brief explanation of the drawing]

[Figure 7] Figure 1 is a perspective view showing the assembly of the first frame with a first support and the second frame with a second support onto the base with a lifting platform of the electric bed 100 shown in Figure 1. [Figure 8] Figure 1 is a partially enlarged side view showing the state in which the support plate provided on the lifting platform of the electric bed 100 supports the first frame and the second frame. [Modes for carrying out the invention]

[0019] An electric bed 100 according to an embodiment of the present invention will be described with reference to the drawings. In each figure, arrow A indicates the head side of the user in a supine position, and the opposite arrow B indicates the foot side of the user in a supine position.

[0020] As shown in Figures 1 and 2, this electric bed 100 mainly consists of a base 10, a lifting platform 20, a lifting drive unit 3 for raising and lowering the lifting platform 20, a first frame 30 located under the upper body of the user in a supine position, a second frame 40 located under the lower body of the user, a first support part 50 tiltably attached to the first frame 30, and a second support part 60 tiltably attached to the second frame 40. The structure includes a first drive unit 1 for tilting the first support unit 50, a second drive unit 2 for tilting the second support unit 60, a connecting member 110 capable of connecting the first frame 30 and the second frame 40, a first fixing member 101 for fixing the first frame 30 to the base 10, a second fixing member 102 for fixing the second frame 40 to the base 10, and a support plate 120 that supports the central part of the entire frame, which is a combination of the first frame 30 and the second frame 40, from below.

[0021] As shown in Figures 3 and 4, the base 10 consists of a rectangular frame supported at its four corners by legs 11, and as shown in Figure 5, a rectangular lifting platform 20, similar to the base 10, is mounted on it via multiple link mechanisms 12 so that it can move up and down.

[0022] As shown in Figure 5, the lifting drive unit 3 is an actuator that moves a piston 3a forward and backward. One end of the piston 3a is rotatably connected to the lifting platform 20, and the other end is rotatably connected to the link mechanism 12. By moving the piston 3a forward and backward, the lifting platform 20 is raised or lowered relative to the base 10, accompanied by the rotation of the link mechanism 12. However, the drive mechanism and drive method are not limited to this and can be any mechanism or method that raises or lowers the lifting platform 20 relative to the base 10.

[0023] The first frame 30 and the second frame 40 are not a single unit but separate parts, and as shown in Figure 6, they are each rectangular in shape. The first frame 30 has left and right vertical frames 31 and 32, a horizontal frame 33 on the side of arrow A and a horizontal frame 34 on the side of arrow B that spans them horizontally, and an intermediate frame 35. Similarly, the second frame 40 has left and right vertical frames 41 and 42, a horizontal frame 44 on the side of arrow A and a horizontal frame 43 on the side of arrow B that spans them horizontally, and an intermediate frame 45.

[0024] As shown in Figure 6, the first support section 50 is mesh-like and supports the user's upper body, mainly the head and back, from below. As shown in Figure 2(c), it is attached to the first frame 30 so as to be tiltable, with the user's head side (arrow A side) higher than horizontal. The tilting of the first support section 50 is performed by the first drive unit 1.

[0025] As shown in Figure 6, the first drive unit 1 is an actuator that moves the piston 1a forward and backward. One end of the piston 1a is rotatably connected to a horizontal rod 14 that abuts against the lower side of the first support unit 50 via a link mechanism 13, and the other end is rotatably connected to the first frame 30. By moving the piston 1a forward and backward, the horizontal rod 14 is pushed up from the side of arrow B to the side of arrow A, accompanied by the rotation of the link mechanism 13, or by lowering the horizontal rod 14 from the side of arrow A to the side of arrow B, causing the first support unit 50 to tilt more on the side of arrow A than on the side of arrow B, or to reduce the tilt. However, the drive mechanism and drive method are not limited to this and can be any drive mechanism or drive method that tilts the first support part 50 relative to the first frame 30. Furthermore, the first support section 50 is provided on the side indicated by arrow A in the first frame 30 and supports the user's upper body, mainly the head and back, from below. On the side indicated by arrow B, a waist support section 55 is fixed to the first frame 30 in a horizontal position and supports the user's waist from below.

[0026] As shown in Figure 6, the second support section 60 is mesh-like and supports the user's lower body from below, and as shown in Figure 2(c), it is attached to the second frame 40 so as to be tiltable, with the user's knees higher than horizontal. The second support section 60 consists of a thigh support section 61 that supports the user's thighs from below and a lower knee support section 62 that supports the lower part of the user's knees from below. The two are connected via a hinge mechanism 15, and the second support section 60 tilts so that the user's knees move up and down, that is, the space between the thigh support section 61 and the lower knee support section 62 bends into a mountain shape, and the height of that mountain increases or decreases. The tilting of the second support section 60 is performed by the second drive unit 2.

[0027] As shown in Figure 6, the second drive unit 2 is an actuator that moves the piston 2a forward and backward. One end of the piston 2a is rotatably connected to the thigh support 61 of the second support unit 60, and the other end is rotatably connected to the second frame 40. By moving the piston 2a forward and backward, the space between the thigh support 61 and the lower leg support 62 is raised or lowered. However, the drive mechanism and drive method are not limited to this and can be any drive mechanism or drive method that tilts the second support part 60 relative to the second frame 40.

[0028] As shown in Figure 6, the connecting member 110 is rectangular in shape and is inserted into the space formed at the end of the left and right vertical frames 31 and 32 constituting the first frame 30 on the side indicated by arrow B, i.e., the end on the second frame 40 side, and the space formed at the end of the left and right vertical frames 41 and 42 constituting the second frame 40 on the side indicated by arrow A, i.e., the end on the first frame 30 side. It is fixed to the vertical frames 31, 32, 41, and 42 from below at two fastening members 115 on the outside and to the vertical frames 31, 32, 41, and 42 from the side on the inside at two fastening members 116 on the outside. Here, bolts are used as fastening members 115 and 116, but the material is not limited to these.

[0029] As shown in Figure 5, the first fixing member 101 is a bolt that fixes the intermediate frame 35 of the first frame 30, which is placed on the support bases 21 and 22 erected on the side of arrow A on the lifting platform 20, i.e., the corner (left and right corners) on the user's head side, to the support bases 21 and 22. The intermediate frame 35 has holes (not shown) that go through from top to bottom, into which the first fixing member 101 (bolt) is fitted. As shown in Figure 5, the second fixing member 102 is a bolt that fixes the intermediate frame 45 of the second frame body 40, which is placed on the support bases 23 and 24 erected on the side of arrow B of the lifting platform 20, i.e., the corner (left and right corner) on the user's foot side, to the support bases 23 and 24. The intermediate frame 45 has holes (not shown) that go through from top to bottom, into which the second fixing member 102 (bolt) is fitted. Here, bolts are used as the first fixing member 101 and the second fixing member 102, but the invention is not limited to these.

[0030] As shown in Figure 5, the support plate 120 is mounted on support bases 25 and 26 located in the central part of the lifting platform 20. It is a long plate extending in the longitudinal direction of the electric bed 100, that is, from arrow A to arrow B, and supports the central part of the entire frame, which is a combination of the first frame 30 and the second frame 40 connected by the connecting member 110, from below without fixing it in place. More specifically, as shown in Figure 8, the horizontal frames 34 of the first frame 30 and the horizontal frames 44 of the second frame 40 are simultaneously supported from below. Here, there is a gap between the opposing horizontal frames 34 and 44, but this gap can be eliminated.

[0031] This electric bed 100 consists of three main components: a base 10 to which the lifting platform 20 and lifting drive unit 3 are attached; a first frame 30 to which the first support unit 50, first drive unit 1 and waist support unit 55 are attached; and a second frame 40 to which the second support unit 60 and second drive unit 2 are attached. These components are transported separately to the installation site and assembled there to complete the electric bed 100. These three items (the base 10 to which the lifting platform 20 and lifting drive unit 3 are attached, the first frame 30 to which the first support unit 50, the first drive unit 1 and waist support unit 55 are attached, and the second frame 40 to which the second support unit 60 and the second drive unit 2 are attached) are somewhat heavy, but can be carried by a single worker.

[0032] At the installation site, as shown in Figure 7, the first frame 30, to which the first drive unit 1 and waist support unit 55 are attached, and the second frame 40, to which the second support unit 60 and second drive unit 2 are attached, are placed on the lifting platform 20. At that time, as shown in Figure 8, the horizontal frames 34 of the first frame 30 and the horizontal frames 44 of the second frame 40 are placed in a position where they are supported by the support plate 120. The first frame 30 and the second frame 40 are connected by a connecting member 110, and the intermediate frame 35 on the side indicated by arrow A of the first frame 30 is fixed to the support bases 21 and 22 of the lifting platform 20 by a first fixing member 101, and the intermediate frame 45 on the side indicated by arrow B of the second frame 40 is fixed to the support bases 23 and 24 of the lifting platform 20 by a second fixing member 102. Note that the order of connection and fixing by the connecting member 110, the first fixing member 101, and the second fixing member 102 is not limited.

[0033] With the electric bed 100 configured in this way, the base 10 with the lifting platform 20 and lifting drive unit 3, the first frame 30 with the first support unit 50 on which the first drive unit 1 is provided, and the second frame 40 with the second support unit 60 on which the second drive unit 2 is provided are separate components. Therefore, they can be easily transported to the installation location, for example, on the second floor. After transport, the first frame 30 and the second frame 40 can be assembled separately to the lifting platform 20 provided on the base 10 at the installation location. Furthermore, when the electric bed 100 is no longer needed, it can be easily disassembled into its components: the lifting platform 20, the base 10 with the lifting drive unit 3, the first frame 30, and the second frame 40, making removal from the installation site straightforward. Furthermore, since this entire process can be performed by a single worker, labor costs can be reduced.

[0034] Furthermore, at the installation site, the first frame 30 and the second frame 40 are connected via a connecting member 110 on the lifting platform 20 on the base 10. The first frame 30 is fixed to the lifting platform 20 via a first fixing part 101 on the side indicated by arrow A, and the second frame 40 is fixed to the lifting platform 20 via a second fixing part 102 on the side indicated by arrow B. However, as shown in Figure 8, the central part of the entire frame, which combines the first frame 30 and the second frame 40, is not fixed, including the connecting member 110, but is supported from below by a support plate 120. Therefore, even if a displacement or distortion occurs in the central part of the entire frame, i.e., on the side indicated by arrow B (second frame side 40) of the first frame 30 and on the side indicated by arrow A (first frame 30 side) of the second frame 40, due to tilting of the first support part 50 or the second support part 60, that part is not fixed to the lifting platform 20, thus preventing particularly large loads from being placed on it. If the central part of the entire frame, that is, the side of arrow B on the first frame 30 (the side of the second frame 40) and the side of arrow A on the second frame 40 (the side of the first frame 30) are fixed to the lifting platform 20, the first support part 50 and the second support part 60 may tilt, or the movement of the user may place a large load on the central part of the entire frame, which may cause damage to that part.

[0035] Furthermore, the connecting member 110 is inserted into the spaces formed at the ends of the left and right vertical frames 31 and 32 that constitute the first frame 30, and into the spaces formed at the ends of the left and right vertical frames 41 and 42 that constitute the second frame 40 that are opposite to it. Since it is fixed from the outside bottom and side of the vertical frames 31, 32, 41, and 42 respectively with fastening members 115 and 116 such as bolts, the connection strength is great and it is stable even when the first support part 50 or the second support part 60 tilts or when the user moves. Furthermore, since the support plate 120 simultaneously supports from below both the horizontal frame 34 that spans the space between the left and right vertical frames 31 and 32 of the first frame 30, and the horizontal frame 44 that spans the space between the left and right vertical frames 41 and 42 of the second frame 40, it ensures that even if there is some misalignment, it will be reliably supported from below.

[0036] In this embodiment, a lifting platform 20 is provided on the base 10 and a lifting drive unit 3 is attached to raise and lower it. However, it is also possible to have a base 10 alone, on which a first frame 30 is provided with a first support unit 50, a first drive unit 1 and a waist support unit 55, and a second frame 40 is provided with a second support unit 60 and a second drive unit 2. Furthermore, the waist support unit 55 may be omitted, and the second support unit 60 may also be tiltable. It is not limited to the configuration consisting of a thigh support unit 61 and a lower knee support unit 62 as in this embodiment.

[0037] Furthermore, in this embodiment, the central part of the entire frame, which connects the first frame 30 and the second frame 40 with a connecting member 110, is supported by a support plate 120 but is not fixed. However, it is also possible to fix it, or to fix the first frame 30 and the second frame 40 separately without connecting them. In this case, there is a risk of load being placed on the fixed part due to misalignment, but this can be suppressed by using a material with superior strength. In this case, there is also the advantage that if the first frame 30 to which the first support part 50, the first drive part 1 and the waist support part 55 are attached and the second frame 40 to which the second support part 60 and the second drive part 2 are attached are separate parts, they can be transported to the installation location separately.
