Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which a bottom of a bed or the like is mounted on a frame supporting the bottom, and when it is unnecessary, it is stored under the bottom. The present invention relates to a retractable side fence in a bed or the like, which can be lifted and held so as to cover.

[0002]

2. Description of the Related Art Conventionally, there are various types of side fences provided on beds and the like (hospital beds, home beds, transfer beds, ICU beds, etc.). For example, what is called an insertion fence is configured to be detachable from an insertion hole formed on a side frame such as a bed. Therefore, the structure is simple and there is no problem in strength. On the other hand, there is a retractable side fence that can be lifted and fixed so as to cover the bottom side only when necessary. According to the retractable side fence, as in the case of the insertion fence, the trouble of removing and attaching each time can be saved, and the usability is good. In addition, a side fence directly fixed to the bottom side has been proposed. According to such a side fence, if it is applied to a bed provided with a bottom up / down mechanism (gatch mechanism), the side fence follows the movement of the bottom even when a gatch operation is performed. Is provided in a position where it is supported from the side. However, if the side fence is completely fixed to the bottom of such a side fence directly attached to the bottom, the side fence may be in the way when the user gets on and off the bed or performs medical treatment. Recently, a retractable side fence directly attached to the bottom has been proposed.

[0003]

However, in the retractable side fence directly attached to the bottom, it is evident that the burden on the bottom increases since the side fence provided with the storage mechanism is supported on the bottom. Although the bottom fence that supports the upper body side is certainly effective, it is considered that there is no problem if the bottom fence, thigh and foot are not necessarily the bottom fence type. The present invention has been proposed in view of the above background, and has a structure to be attached to a frame supporting a bottom of a bed or the like. The purpose of the present invention is to provide a retractable side fence in a bed or the like that can be lifted and held so as to cover the bottom side from below the bottom, and does not require time and effort for attachment and detachment, thereby improving operability and usability. And

[0004]

In order to solve the above-mentioned problems, according to the present invention, a column is mounted on a bed frame supporting a bottom of a bed or the like so as to protrude from below the bottom to above the bottom. The supporting portion is rotatably supported on the upper end side, and the support portion is rotatably attached to a receiving bracket provided on a bed frame supporting the bottom via a base frame portion while the lower end portion is rotatably supported. A first stay rotatably attached to the fence, and a pair of second stays arranged adjacent to both side surfaces of the first stay, wherein the fence protrudes upward from the bottom. When the first stay and the second stay
A restraining means for restraining the stay is provided. The present invention also provides
At the position of the bed frame that supports the bottom from the knee to the foot side, such as a bed having a floor undulating mechanism, a column is attached so that it can protrude from below the bottom to the top of the bottom, and can rotate to the upper end side of this column. The support section is configured to support a fence, and the support section is rotatably attached at a lower end via a base frame to a receiving bracket provided on a bed frame that supports the bottom, while the upper end is rotatable about the fence. A first stay attached to the first stay and a pair of second stays arranged adjacent to both side surfaces of the first stay. A restraining means for restraining the second stay is provided. In the above-described configuration, the first stay or the second stay may be provided with an urging means that acts as an auxiliary force in a direction in which the support portion protrudes from below the bottom to above the bottom.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to an embodiment shown in the accompanying drawings.
A bed 1 shown in FIG.
The retractable side fence 2 is mounted on a bed frame that supports the bottom 3 of the bed 1, that is, on a main frame 4, with a column 5 that can protrude from below the bottom 3 to above the bottom 3. The fence 6 is rotatably supported.

In the retractable side fence 2 having the above-described structure, the column 5 is rotated via a base frame 8 screwed to a receiving metal 7 provided on the main frame 4 supporting the bottom 3 as shown in FIG. It is movably mounted. That is, the support 5
Has a first stay 5a rotatably attached to the base frame portion 8, and a pair of second stays 5b adjacent to both side surfaces of the first stay 5a. In addition, the support 5
The first and second stays 5a, 5b constituting the support portion 5
And a restraining means 9 for holding the fence 6 above the bottom 3 in a protruding state, and a release lever 9a for releasing the restraining means 9 is provided. Further, at a place where the first stay 5a constituting the support portion 5 is attached to the base frame portion 8, an urging means for urging the support portion 5 and the fence portion 6 to protrude upward from the bottom 3 such as a coil spring 1 is provided.
0 is provided so that the coil spring 10 acts as an auxiliary force when lifting the fence 6. The urging means includes a coil spring 10
In addition, a rotary damper, a compression coil spring, and other well-known components can be applied.

The first and second stays 5a and 5b constituting the support portion 5 will be described in more detail. As shown in FIG. 5, the first stay 5a has a hook-like side shape, while the second stay 5a has a second stay. 5b has a substantially rectangular shape in the side surface, and the mounting interval of the first and second stays 5a and 5b on the base frame portion 8 side and the mounting of the first and second stays 5a and 5b on the fence portion 6 at the upper end. The intervals are equal.

The fence 6 is made of synthetic resin and is integrally formed with openings 11 and 12 in front and rear of the upper longitudinal side.
Is provided. These openings 11 and 12 can be used as grips.

In the retractable side fence 2 described above, for example, when a patient is lying on the bed 1, the retractable side fence 2
Is lifted upward from below the bottom 3 and held. When the retractable side fence 2 is below the bottom 3 (FIG. 4)
), That is, from the storage state, the openings 11, 1
