まで上昇可能である。 As is clear from a comparison between Figures 4 and 6, the upper movable part 3 simply moves up and down without swinging in the left and right front and rear directions, so for example, if it is a floorboard for a patient's bed, it should be brought as close as possible to the wall 29. Even if there is, there will be no interference. Therefore, the bed is a wall 2
It has the advantage of being able to be installed in as many places as possible. Furthermore, the vertical movement range is wide, and it is possible to rise from a flat position as shown in FIG. 4 to a tall position as shown in FIG.

ある。 Furthermore, even if the upper movable part 3 is long, if the number of link mechanisms 1 is increased correspondingly, it will not cause lateral shaking or tilting, and will be stable.
Can go up and down. Further, as shown in the figure, since the screw shaft 24 and the nut member 25 only need to be screwed together at one location, there is little power loss and easy upward and downward movement is possible. Also, screw shaft 2
4 has the advantage of being the shortest and having the lowest production cost.

に設置して使用することも好ましい。 Furthermore, if the lower fixed part 2 is constructed of vertical beams 4, 4 (and cross beams added as desired), the upper movable part 3 in the lowest lowered state can be made extremely short, for example, for a bedridden elderly person, etc. As a bed, it has the great advantage that it does not cause anxiety to the elderly and can be raised to a sufficient height only when visiting a doctor or disposing of defecation. Moreover, it is also preferable to use it by installing it on an existing stand.

点は大きい。 As described above, the present invention includes a lift plate 7 having a lower end portion 9 attached to the lower fixed portion 2 so as to be movable in the longitudinal direction A, and an upper end portion 11 attached to the upper movable portion 3 so as to be swingable, and the lower fixed portion. The lower end portion 15 is swingably attached to the compression plate 8 which is swingably connected to the upper and lower intermediate positions of the lift plate 7. Forming a letter-shaped link mechanism 1,
The lift plate 7 and the compression plate 8 are both formed into a rectangular plate shape, and the lower end 9 of the lift plate 7 and the lower end 15 of the compression plate 8 are placed at the same height. Further, a plurality of the link mechanisms 1 are arranged at predetermined intervals, and the lower ends 9 of the lift plates 7 of the link mechanisms 1 are connected to the tie rods 1.
A plurality of link mechanisms 1...
At the same time, the lower end 9 is connected to the lower end 9 of the lift plate 7 of one of the plurality of link mechanisms 1 or to the tie rod 18 in the longitudinal direction A.
Since the drive mechanism 19 is connected to the drive mechanism 19 for moving the slender (elongated) upper movable section 3, increasing the number of link mechanisms 1 will ensure stability even when heavy loads are applied. It can be moved up and down. If an uneven load is applied to the upper movable portion 3, such as when a sick person sits in a corner of the bed, the link mechanism 1 of the present invention can sufficiently withstand it. In particular, it has a great advantage of being able to rise and fall easily without wobbling even under uneven loads.

ある。 In addition, the plurality of link mechanisms 1... are connected to the tie rod 1.
Although the link mechanisms 1 are simply connected at 8, the plurality of link mechanisms 1 can be reliably synchronized, so that the upper movable part 3 can always be kept in a horizontal state. Furthermore, since the synchronization of the link mechanism 1 is reliable, only one drive mechanism 19, that is, a threaded portion is required. Therefore, power loss is small and manufacturing is easy. Also, lift plate 7
Since the lower end 9 and the lower end 15 of the compression plate 8 are arranged at the same height, the upward movable part 3 in the lowest lowered state can be made extremely short, and the minimum height and maximum height can be The difference can be made sufficiently large, and the adjustment allowance is large, making it ideal for beds for patients, etc., which can be kept low to give a sense of security to patients, and can be raised to a sufficient height for medical examinations and various treatments. It's very convenient. Furthermore, since both the lift plate 7 and the compression plate 8 are formed into a rectangular plate shape, there is no lateral vibration, and the plate is highly rigid and durable.
