Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a back-lift compatible side rail that can be used with a bed having a back-lift mechanism.

(Prior Art) Generally, it is well known that side rails provided on the side frames of a bed have the function of supporting a patient. These side fences are commercially available with various structures, such as fences that can be simply inserted into the side frame, foldable fences, and fences that rotate and lower.

(Problem to be solved by the invention) By the way, the side rails with the above-mentioned structure function when the bed is in a normal state, and when installed on a bed with a back-raising mechanism, the side rails with the structure described above function when the bed is in a normal state. The upper end of the side rails only extends to the patient's abdomen. For example, in the event of an emergency, the patient may fall from the back floor toward the side of the bed, and the side rails may not be able to support the patient's body. In the worst case scenario, concerns have been raised about patients climbing over the side rails and falling down.

The present invention has been made to overcome the above-mentioned problems.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a bed that is divided into a back floor, a lumbar floor, and a leg floor, and has a back raising mechanism, and a position corresponding to the back floor. is provided with a first side fence and a second side fence at a position corresponding to the waist floor and the leg floor, and the first side fence is configured such that one end of the base of the first side fence is attached to the back floor, The other end of the first side fence and the second side fence are pivoted to each other in the rotational axis of the back floor including the pivot point between the back floor and the lumbar floor, and the first side fence and the second side fence are With the side fence,
This feature is characterized in that the beds are installed offset from each other in the width direction of the bed.

Moreover, the first side fence and the second side fence in the present invention have a foldable structure.

(Function) The first side fence and the second side fence of the present invention have a foldable structure, so when getting on and off the bed or undergoing treatment, simply fold them and the bed side will be opened and will not get in the way. Nothing happens.

By raising the back of the bed, the first side rail rises together with the back bed. Since the first side rail is attached to the back floor, its positional relationship with the back floor remains unchanged even when the back is raised, and it can support the patient. At that time, since the first side fence and the second side fence are provided at different positions in the bed width direction, the first side fence and the second side fence may collide with each other by raising the back. Nothing happens.

(Example) Next, an example of the back-lift compatible side fence according to the present invention will be described below with reference to the attached drawings.

In FIG. 1, reference numeral 1 indicates a back-lifting type side fence, and this back-lifting type side fence 1 is attached to a bed 2 having a back-lifting mechanism. That is, the back-lift compatible side fence 1 includes the back floor 3, waist floor 4, and leg floor 5 of the bed 2, which are divided into parts.
A first side fence 6 provided at a position corresponding to the back floor 3
and a second side fence 7 provided at a position corresponding to the waist floor 4 and leg floor 5. The first side fence 6 and the second side fence 7 have a foldable structure, and each has a base 8a, 8b and a base 8.
It comprises struts 9a, 9b foldably attached to the struts 9a, 8b, and upper frames 10a, 10b attached to the upper ends of the struts 9a, 9b. ，
10b, there are standing position holding mechanisms 11a, 11b.
is provided. This standing position holding mechanism 11a, 1
1b includes locking members 12a, 12b attached to the pillars 9a, 9b, and locking members 12a, 12b.
b, and the protruding pieces 13a, 13b are engaged with the locking members 12a, 12b by operating the handle under the bias of a spring force, and the protruding pieces 13a, 13b are engaged with the locking members 12a, 12b by operating the handle. This keeps the first side fence 6 and the second side fence 7 in an upright position.

One end of the base 8a of the first side fence 6 is fitted into a pipe 14 provided on the lower surface of the back bed 3 along the width direction of the bed via a protruding piece 15.
The base 8b of the second side fence 7 is attached to the side frame 16 (see FIGS. 2 and 3).

The other end of the base 8a of the first side fence 6 and the base 8b of the second side fence 7 are located at the rotational axis A of the back floor 3 including the axis attachment point of the back floor 3 and the waist floor 4. They are pivotally connected to each other by a hinge 17. moreover,
The first side fence 6 is provided at a position protruding to the outside of the side frame 16 so as to be close to the back floor 3, while the second side fence 7 is provided at a position protruding to the outside of the side frame 16 so as to be separated from the waist floor 4 and leg floor 5. The first side fence 6 and the second side fence 7 are provided so that a deviation L occurs in the bed width direction (see FIG. 2).

This back-liftable side fence 1 functions as follows.

Since the first side fence 6 and the second side fence 7 that constitute the back-lift compatible side fence 1 have a foldable structure,
When getting on and off the bed or receiving treatment, simply fold it up and the bed side will be open, so it won't get in the way in any way. Note that the folding of the first side fence 6 and the second side fence 7 is performed by the standing position holding mechanism 11a,
This is accomplished by operating the handle of the protruding pieces 13a, 13b of 11b against the spring force to retract them from the locking members 12a, 12b.

By raising the back of the bed 2, the first side rail 6 rises together with the back bed 3 about the rotation axis A. Since one end of the base 8a of the first side fence 6 is locked to the pipe 14 of the back bed 3, the positional relationship between the first side fence 6 and the back bed 3 remains unchanged, and the patient can move from the floor to the bed 2. Even if the patient falls to the side, the patient will be supported by the first side rail 6 and the patient will be able to stay on the bed 2.
This makes it possible to avoid the worst case scenario of falling down. At that time, the first side fence 6 and the second
Since the side fences 7 are provided at different positions from each other in the width direction of the bed 2, the first side fence 6 and the second side fence 7 will not collide with each other when the back is raised ( (See Figure 4).

(Effect of the invention) According to the invention, when raising the back of the bed,
The first side fence rises together with the dorsal floor. Since the first side rail is attached to the back floor, its positional relationship with the back floor remains unchanged even when the patient's back is raised, and even if the patient falls from the floor toward the side of the bed,
The patient is supported by the first side rail, making it possible to avoid the worst case of the patient rolling off the bed.

At that time, since the first side fence and the second side fence are provided at different positions in the width direction of the bed, the first side fence and the second side fence collide with each other when the back is raised. There is no such thing.

Furthermore, since the first side fence and the second side fence are of a foldable structure, they do not interfere with getting on and off the bed or getting treatment.
