(Described later), an interlocking rod 10 connected between the link 8 and the restriction link 9 so that the link 8 and the restriction link 9 can be interlocked, and the interlocking rod 10 is urged in one direction. And a spring member 11 connecting the interlocking rod 10 and the hollow base frame 4 as described above. A pair of columns 6, 7 are attached to the fence main body 12 rotatably mounted between the tops of the pair of columns 6, 7 and the mounting position of the pair of columns 6, 7 and the column main body 12. 7
Locking mechanism 1 for restraining fence main body 12 to support at least a pair of columns 6 and 7 in an inclined state and a vertical state.
3 is provided.

The link 8 and the regulating link 9 in the pair of columns 6 and 7 have the same length. Further, the base shaft 5 that supports the restriction link 9 and the column 7 is provided with a rotation restricting unit that restricts the rotation range of the columns 6 and 7. That is, the rotation restricting means includes a link stopper 14 projecting in a fan shape from the base shaft 5 supporting the column 7, and a step 15 for restricting the rotation range of the column 7 by contacting the link stopper 14 with the restriction link 9. , And 16, and regulating shafts 17, 18 for defining a rotation range of the regulating link 9 are provided on the inner wall of the hollow base frame 4 in the vicinity of both side surfaces of the regulating link 9.

A spring member 11 for connecting the interlocking rod 10 and the hollow base frame 4 always urges the interlocking rod 10 rightward in the drawing.

Next, the locking mechanism 13 for restraining the fence main body 12 will be described. As shown in FIG.
And the stopper fitting 20 is provided with locking holes 21 and 22 for locking a stopper pin to be described later, while the fence main body 12 covers a portion from the top of the support 7 to the stopper fitting 20. Further, the stopper cover 23 is axially fixed so as to be able to be pressed in a seesaw manner. The stopper hole 23 provided in the stopper fitting 20 is provided at a position of the stopper cover 23 facing the stopper fitting 20.
A stopper pin 24 for locking to the first and the second 22 is provided via a tension spring 25 (see FIG. 4). The stopper pin 24 is urged by the tension spring 25 so as to be selectively locked in the locking holes 21 and 22 of the stopper fitting 20 at all times. When the column 7 and the column 6 are in the vertical state, the stopper pin 24 is locked in the locking hole 22 of the stopper fitting 20, and the columns 6, 7 are rotated counterclockwise from the vertical state by 41. The stopper pin 24 is locked in the locking hole 21 of the stopper metal fitting 20 when it is rotated and inclined.

Further, at this time, a link stopper 14 projecting in a fan shape from the base shaft 5 constituting the rotation restricting means has an angle with the step 15 of the restricting link 9 set to 41 °.
When the posts 6 and 7 are rotated counterclockwise from the vertical state by 41 °, the link stopper 14 is rotated by 41 ° together with the base shaft 5 and abuts the step 15 of the regulating link 9, and the column is further extended. 6, 7 are not inclined. In addition, prop 6,
7 rotates clockwise 102.5 ° from the vertical state to store the fence main body 12 below the side frame 2, and from this stored state until the columns 6, 7 are moved to the vertical state. The step 16 of the regulating link 9 and the link stopper 14 are in contact with each other by the spring member 11, and the supporting column 7 and the regulating link 9 are integrally rotated.

The retractable side fence of a bed or the like according to the present invention is constructed as described above. Next, this operation will be described. When the side fence is not required during treatment, fence body 1
By releasing the locking mechanism 13 of FIG. 2 and rotating the columns 6 and 7 clockwise by 102.5 ° from the vertical state, the fence main body 12 can be set in the retracted state below the side frame 2. At this time, the rotation of the columns 6 and 7 causes the link 8 together with the base shaft 5 to rotate.
And the regulating link 9 rotates clockwise, so that the interlocking rod 10
Is displaced leftward in the figure against the spring force of the spring member 11. Further, the support 7 and the restriction link 9 rotate integrally with the step 16 of the restriction link 9 and the link stopper 14 of the base shaft 5 in contact with each other (see FIG. 5).

Next, when using the fence main body 12 as a fence, hold the fence main body 12 and move it counterclockwise from the stored state.
The columns 6, 7 are rotated by 102.5 ° to be in a vertical state.
At this time, the link 8 and the regulating link 9 rotate counterclockwise, and the interlocking rod 10 moves rightward in the figure. Interlocking rod 10
Since the urging force of pulling to the right by the spring member 11 is applied to the support member 6, when the fence main body 12 is held and the columns 6 and 7 are set to the vertical state in the counterclockwise direction from the retracted state, the spring member 11 is The operation can be performed as an auxiliary force, and the labor for lifting can be reduced. Also, since the spring members 11 are acting until the columns 6, 7 are in the vertical state,
Step 16 of regulating link 9 and link stopper 14 of base shaft 5
Are rotated together in a state where they are in contact with each other, and the columns 6, 7
When the control link 9 is in the vertical state, the control link 9 comes into contact with the control shaft 18 and the control link 9 cannot be further displaced. When the columns 6 and 7 are in a vertical state, the stopper pin 24 of the stopper cover 23 is locked in the locking hole 22 of the stopper fitting 20 by the locking mechanism 13 at the tip of the column 7, so that the pair of columns 6 and 7 are connected. It can be held vertically (see FIG. 6).

When the support is necessary when getting on and off the bed 1, if the columns 6 and 7 are further rotated counterclockwise from the vertical state, the regulating link 9 is moved when the columns 6 and 7 are in the vertical state. Since the control link 9 is already in contact with the control shaft 18 and cannot be further displaced,
Only the columns 6, 7 are displaced. When the columns 6 and 7 are displaced by 40 °, the link stopper 14 of the base shaft 5 comes into contact with the step 15 of the regulating link 9, so that the columns 6 and 7 can be prevented from further tilting. At this time, in the locking mechanism 13 at the tip of the column 7, the stopper pin 24 of the stopper cover 23 is locked in the locking hole 21 of the stopper fitting 20, thereby holding the pair of columns 6, 7 in the above-described inclined state. (See FIG. 7). When the pillars 6 and 7 are in the inclined state, the fence main body 12 is directed from the position of the pillars 6 and 7 in the vertical state to the head side of the bed 1 and close to the bed 1. Since the bed is inclined toward the head side of the bed 1, the side of the floor on the leg side of the bed 1 is opened, so that the patient can utilize the fence body 12 as an assistance means. In addition, as described above, the fence main body 12 functions as a fence when the floor is in a flat state in addition to the clues when getting on and off the bed 1 when the columns 6 and 7 are inclined. When the pair of columns 6 and 7 are returned to the vertical state, the fence main body 12 has an appropriate height as a fence when the floor is raised (see FIG. 1).

[0014]

As described above, according to the present invention, in addition to functioning as a fence, it is possible to hold the fence at an appropriate position as a support when getting on or off a bed, and to provide a side fence when not in use. Since it can be stored under the frame, it is not necessary to attach or detach it according to the usage conditions as in the past, and it has a simple structure and easy operation, so that it is easy to use. Greatly improve.
