JPH0775657A - Bottom structure of bed provided with floor part elevating/declining mechanism - Google Patents

Abstract

PURPOSE:To constitute the bottom structure of bed so that it can be fitted to the body of a user, and the deviation of mattress on the bottom can be also prevented. CONSTITUTION:In connecting parts of a back bottom 1a and a waist bottom 1b, and the waist bottom 1b and a knee bottom, a flexible relay bottom 2 is provided so as to connect the back bottom 1a and the waist bottom 1b, and the waist bottom 1b and the knee bottom. Also, on the relay bottom 2, a nonskid member 3 of a mattress is arranged. In such a way, when a floor part is elevated and declined, the bend angle of the connecting part of the floor part becomes moderate so as to be fitted to the body of a user, and a deviation of the mattress on the bottom can be also prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, particularly in a bed provided with a floor undulating mechanism, fits the user's body by making the bending angle of the connecting portion of the floor gentle when the floor is undulated. In addition, the present invention relates to a bottom structure of a bed having a floor undulating mechanism capable of preventing the mattress on the bottom from being displaced.

[0002]

2. Description of the Related Art Recently, many beds have a floor undulating mechanism, and various beds are used.

[0003]

However, in a typical bed structure, the back bottom and the waist bottom are often simply connected by a hinge so that they can be bent. The connection point here is a pivot of the floor. It is designed to make ups and downs. Therefore, during the up-and-down motion, the vicinity of the connecting portion between the back bottom and the waist bottom is narrowed, and the mattress is pressed by the back bottom, and as a result, the patient's waist is pressed by the mattress, so that the patient presses the waist and abdomen. I feel. In addition, due to the elasticity of the mattress, when the back bottom is raised, the mattress exerts a force to move toward the leg side, resulting in displacement. From such a background, the present invention makes the bending angle of the connecting portion of the floor gentle when the floor is undulated so that it fits the user's body, and at the same time, the displacement of the mattress on the bottom is prevented. An object of the present invention is to provide a bed having a floor undulation mechanism that can be prevented.

[0004]

In order to solve the above problems, the present invention relates to a bed provided with a floor undulating mechanism, in which a plurality of bottoms are connected to each other at the connecting points of the bottoms. It is characterized in that it is provided so as to span an extendable relay bottom between them. In the above-mentioned configuration, the anti-slip member of the mattress is arranged on the relay bottom.

[0005]

[Operation] When the floor undulation mechanism is activated to wake up the bottom, the bottom wakes up centering on the connection point.
The entire length of the relay bottom spanned between these bottoms recedes, and even if you wake up to the maximum tilt angle, the connecting point will come out with the relay bottom tilted, so press the mattress at the bending point. There is no such thing as a crush. When the bottom is getting up, the mattress receives a force in the direction of the legs by retracting the entire length of the relay bottom, but the slippage member can prevent the mattress from slipping.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a bottom structure of a bed provided with a floor undulating mechanism according to the present invention will be described below with reference to the accompanying drawings with reference to an embodiment. FIG. 1 shows a bed bottom 1 having a floor undulating mechanism. This bottom 1 is
It is divided into a back bottom 1a, a waist bottom 1b, a knee bottom 1c, and a leg bottom 1d, which are sequentially connected so as to be bendable.
That is, the floor undulation mechanism (not shown) raises the back,
It is configured to raise the knee.

At the connecting points of the back bottom 1a and the waist bottom 1b, and between the waist bottom 1b and the knee bottom 1c, there are expandable and contractible relay bottoms 2, a back bottom 1a and a waist bottom 1b, and a waist bottom 1b and a knee bottom. It is provided so as to connect with 1c. A slip-prevention member 3 of a mattress (described later) is arranged on the relay bottom 2 (FIG. 2).
reference). In addition, at the connection points between the back bottom 1a and the waist bottom 1b, and between the waist bottom 1b and the knee bottom 1c,
FIG. 3 shows a connecting portion between the back bottom 1a and the waist bottom 1b, and more detailed description will be made. The back bottom 1a and the waist bottom 1b are flexibly connected by hinges 4 in the vicinity of both widthwise end surfaces. An arrangement space 5 corresponding to the outer shape of the relay bottom 2 is formed between the hinges 4 near both end surfaces in the width direction.

The relay bottom 2 is composed of two strip-shaped bottoms 2a and 2b, and one strip-shaped bottom 2a is
The other strip-shaped bottom 2b is configured to be retractable. Then, the strip-shaped bottom 2a is placed in the arrangement space 5 between the hinges 4 in a state where the strip-shaped bottom 2b is housed, and the back bottom is formed on the inner wall forming the arrangement space 5 on the side of the back bottom 1a and the waist bottom 1b. 1
bolt 6 so that it can be displaced relative to a and the waist bottom 1b.
It is installed by. The strip-shaped bottom 2a is arranged in the arrangement space 5 on the waist bottom 1b side, and the strip-shaped bottom 2b is arranged in the arrangement space 5 on the back bottom 1a side. An anti-slip member 3 is attached to the upper surface of the strip-shaped bottom 2a, that is, the contact surface with the mattress.

In the bed bottom structure 2 having the floor undulation mechanism as described above, when the floor undulation mechanism is activated to wake up the bottom 1 (back bottom 1a), the back is centered around the connecting point. The bottom 1a gets up. At this time, the strip bottom 2b on the back bottom 1a side retracts into the strip bottom 2a on the waist bottom 1b side, so that the back bottom 1
The entire length of the relay bottom 2 spanned between a and the waist bottom 1b retreats. In the strip bottom 2a on the waist bottom 1b side, a connection point between the back bottom 1a and the strip bottom 2b (attachment portion by the bolt 6) rises together with the back bottom 1a, and the relay bottom 2 has a strip bottom 1b and a strip shape. Bottom 2a
Wake up around the bolt 6 attachment part of and. Since the bolt 6 attachment portion between the waist bottom 1b and the strip bottom 2a is located on the left side in the drawing from the position of the hinge 4 which is the connecting portion between the back bottom 1a and the waist bottom 1b, the back bottom is shown. 1a
Even if the user wakes up to the maximum inclination angle, the relay bottom 2 only wakes up so as to approach the inclination angle that is smaller than the inclination angle of the back bottom 1a, and the mattress 7 at a position corresponding to the relay bottom 2 Is only slightly extruded in the bending inner direction of the mattress 7, and is not crushed. At that time, the strip bottom 2a on the spine bottom 1a side recedes as the spine bottom 1a gets up, and the mattress 7 corresponding to the strip bottom 2b moves toward the leg bottom 1d side. Although a force is applied, the strip-shaped bottom 2a on the waist bottom 1b side only wakes up, and therefore the slip-preventing member 3 can prevent the mattress 7 from being displaced.

[0010]

As described above, according to the present invention, when the floor portion is undulated, the bending angle of the connecting portion of the floor portion is made gentle so that it fits the user's body, and at the same time, the bottom portion is also fitted. Displacement of the upper mattress can be prevented.
