Description

A low bed capable of maximum height The present invention relates to a low bed capable of maximum height, wherein a lower block and an upper block are respectively connected to both ends of an asymmetric L-shaped link that rotates on a bracket provided on a frame, and the other end of a moving means, one end of which is connected to the frame, is connected to the lower block, and when the lower block moves, the upper block connected to the other end of the link moves in a parallel vertical direction around the frame. Generally, beds for inpatients at hospitals or clinics, or for patients receiving care at home or in nursing facilities due to chronic diseases, are designed to allow for adjustment of the angles of the backrest, thigh plate, and tibia plate to assist patients with limited mobility and reduced muscle strength who find it difficult to independently assume strenuous postures, such as raising their upper body. Most of these electric beds are configured for angle adjustments of the backrest, saddle, and thigh plate, but they do not take into account the individual patient's height or the ratio of trunk to lower limb lengths. To improve upon such problems, the technology of an adjustable frame is presented in the prior art patent No. 1398388, and as shown in FIG. 1, the adjustable frame (10) includes a rectangular main frame (100) for forming the entire skeleton, and all components such as a back plate (200), a buttock plate (300), and a thigh plate (400) are combined thereon. And, when the back plate (200) is connected to the buttock plate (300) as a first hinge part (310), the retractable rod of the first cylinder actuator (220), which is rotatably coupled to the transverse frame (110) on one side of the main frame (100), is hinge-coupled to the back plate protrusion arm (210) protruding from the back plate (200), and the buttock plate (300) is provided with a protrusion plate (320) that can be inserted into the space between the bottom plate and the thigh plate (400). Additionally, the thigh plate (400) is positioned adjacent to the buttock plate (300), and a pair of slide rods (120) fixedly installed on the main frame (100) are connected to a second cylinder actuator (510) that is rotatably coupled to the thigh plate, and stoppers (125) are provided at both ends of the sliding rods, and the minimum/maximum distance between the buttock plate (300) and the thigh plate (400) is limited by the stoppers (125). Additionally, a third hinge portion (455) is provided at the other end of the thigh plate (400), and a calf plate (600) is hinge-fixed to the third hinge portion (455). To adjust the length of the thigh plate (400), the thigh plate (400) is composed of two separate plates, a pivot plate (410) and a sliding plate (450). The pivot plate (410) is provided with a pivot plate protrusion arm (415) similar to a back plate protrusion arm (210), so that the rod of the second cylinder actuator (510) is pivotally coupled. However, the above-described adjustable frame has a limitation on the height of the rise because the back plate (200) and the thigh plate (400) are connected to the frame (100) by a first hinge part (310), and there is a disadvantage that the load increases when rotating because an actuator (220) is connected to one end of the back plate (200) and the thigh plate (400). FIG. 1 is a schematic diagram illustrating a conventional adjustable frame structure. FIG. 2 is a perspective view illustrating a low bed according to the present invention. FIG. 3 is an operating state diagram of a low bed according to the present invention. FIG. 4 is a diagram showing the stationary and moving states of a low bed according to the present invention. FIGS. 5 to 7 are each diagrams of a low bed equipped with an inclined plate according to another embodiment of the present invention, the operating state of the inclined plate of the low bed, and the unfolded and height-adjusted state of the inclined plate. Hereinafter, embodiments of the present invention will be described in detail based on the attached drawings. As illustrated in FIGS. 2 to 7, the low bed (100) of the present invention is pivotally connected to a bracket (130) that is connected to protrude from the upper part of the frame (110) so as to have an asymmetrical L-shape on the side and a link (150) that is connected to it so as to be rotatable. At this time, the link (150) is composed of a rotation axis (151) in a plane, a plurality of lower links (152) coupled to the rotation axis, and a single upper link (154), and has an L-shaped form that is bent as shown in FIG. 3, with the point of bending corresponding to the rotation axis. And, the lower and upper parts of the above link (150) are respectively connected to the lower block (210) and the upper block (230). In addition, the other end of a moving means (300), which has one end connected to the frame (110), is connected to the lower block (210). At this time, the above moving means (300) is
