Foot bottom support structure for bed

Abstract

In a conventional support structure where the position for supporting a foot bottom end can be set to high and low positions with a knee bottom raised. A change from the high position to the low position can be made only when the knee bottom is raised. When the knee bottom is lowered, the setting is cancelled and set to the high position. One end side of the knee bottom (2) is pivotally and liftably supported on a bed frame (1). One end side of a foot bottom (6) is pivotably connected to the other end side of the knee bottom (2). A support stay (7) is pivotaby connected to the lower side on the other end side of the foot bottom. Support means (11) of a support section (9) formed on the front end side of the support stay (7) is connected to the bed frame. The support means is constructed from a guide section (12) and an engagement section (13) for movably supporting the support section of the support stay. The guide section can support the support section that moves as the knee bottom pivots in its pivot range. The engagement section is provided above or below the end section side of the guide section where the support section is located when the knee bottom lowers.

Description

technical field [0001] The invention relates to a support mechanism for a leg bottom cushion on a bed. Background technique [0002] At present, as a bed for medical use or home use, the bed can be raised and lowered by rotating the back bottom or the knee bottom, thereby supporting the user on the bottom in an appropriate posture according to the situation, and this type of bed has been widely used. [0003] One end side of the leg bottom pad is rotatably connected with the knee bottom pad. In the prior art bed, there is a bed in which the other end side of the leg bottom pad is usually supported by the bed frame support surface, and there is also a bed in which the leg bottom pad The lower side of the other end side is rotatably connected to the support stay, and the bed above the bed frame can be supported by the support stay. [0004] For example, Patent Document 1, by rotatably connecting the support stay under the other end side of the leg bottom pad, and supporting t...

[0014] In addition if Figure 16 As shown, when the knee bottom pad b and the leg bottom pad f are in a horizontal state, since the support part i cannot be moved to the engagement recess n, it can only be moved after the knee bottom pad b is rotated and raised, so it moves to Figure 17 Manipulation of the state of the bottom pad shown is cumbersome
