Description

[Detailed description of the invention] [Industrial application field] This invention relates to a bed used in hotels, general households, etc.

[Prior art and its problems]

Conventionally, as shown in FIG. 5, when installing a bed body 1 in each room of a hotel or the like, one corner of both side surfaces _1a and _1b of the bed body 1 is placed on both corner walls W1 and W2 of the room R. It is common practice to install them so that they are in contact with each other.

However, when the bed is installed like this,
When cleaning the room every day or making the bed by replacing sheets, overlay blankets, etc., the bed body 1 is moved to clean the interior corner on both walls W ₁ and W _{2 .}
The above-mentioned work is facilitated by forming a passageway that the worker can pass between, but as is well known, this type of bed main body 1 is very heavy and the height is too high for indoor use. As the ceiling height tends to be lowered to match the height of the ceiling, the working posture is difficult, especially for middle-aged to elderly female workers, who are forced to move the bed due to their stooped posture. Not only is it easy to injure your lower back, but also
As shown in the figure, the bed body 1 that was separated from both indoor corner walls W ₁ and W ₂ is moved back to both indoor corner walls W 1 and W 2 .
When W ₁ and W ₂ were moved back to their original contact positions, the bed body 1 moved irregularly as shown by the two-dot dashed line and collided with the indoor corner wall diagonally, causing the bed to completely collapse. Both wall surfaces 1a, 1b of main body 1
There were various inconveniences, such as requiring a lot of time and effort to ensure that the wall surface W ₁ and W ₂ were in contact with both indoor corner walls W 1 and W 2 .

[Problem that the invention attempts to solve]

This idea was developed based on the above-mentioned circumstances, and it facilitates the movement of the bed body, which is installed in contact with both walls in the corner of the room, and allows it to be moved back to its original position after cleaning or making the bed. The object of the present invention is to provide a bed in which the movement and return of the bed can be easily performed.

[Means for solving problems]

In order to achieve the above object, the present invention includes a base,
It has a flat rectangular cushion body placed on the base, and a link mechanism that is attached to the base and supports the cushion body so as to be able to move up and down. In a bed installed in contact with both corner walls of a set, the cushion body is guided by the link mechanism and moves upward while moving in a direction away from the corner walls, and the base A width dimension of the cushion body is narrower than a width dimension of the cushion body, and a predetermined distance is set between one side surface of the base and a corner wall surface.

[Effect]

The above bed is one of the flat rectangular cushion bodies.
It is installed with both side surfaces of each corner in contact with both walls of one set of corners indoors. From this state, in order to move the bed away from both corner walls as necessary, such as during cleaning, the base is not moved and only the cushion body placed on the base is lifted. Since the cushion body is supported by a link mechanism, it is guided by the link mechanism and moves upward while moving in a direction away from both corner walls, thereby forming a gap between the cushion body and the corner walls. On the other hand, the width of the base is preliminarily narrower than that of the cushion body, and a distance is set between the base and one corner wall surface. Therefore, when the cushion body is lifted, a working passage is formed between the entire bed and one corner wall surface to facilitate cleaning and the like. After cleaning, etc., to return the bed to its original position, it is sufficient to simply lower the cushion body by following the link mechanism.

[Example of idea]

This invention will be explained below with reference to an embodiment shown in FIGS. 1 to 4. In addition, in the illustrated embodiment of this invention, FIGS.
The same reference numerals are used for the parts whose configurations overlap with the conventional structure shown in the figure, and the explanation thereof will be omitted.

That is, in this invention, in the cushion body 2 and the base 3 which are vertically separable and which constitute the bed main body 1, the cushion body 2 having a rectangular plane can be raised and lowered via a link mechanism 4, which will be described later, so that it can be used for cleaning or bed making. By lifting and floating the cushion body 2, the bed height can be raised from the normal operating height _H0 to the working height H, as shown in FIG. Both side surfaces 2 of one corner of the cushion body 2 in contact with both corner walls W ₁ and W ₂ of the room R
a and 2b are spaced apart from both wall surfaces W ₁ and W ₂ of the indoor corner so that gaps a and b forming a working passage are formed therebetween.

By the way, as shown in detail in FIG. 3, the link mechanism 4 described above includes a pair of upper and lower frames 5 and 6 facing each other at the front and rear of the bed body 1, and a transition between the upper and lower frames 5 and 6 from a tilted state to an upright state. support links 7 and 8 rotatably supported by the lower frames 6 and 8; and a rotation shaft 9 consisting of a torsion bar connected to each of the links 7 and 8 located diagonally between the pair of lower frames 6 and 6. The rotation shaft 9 is composed of a connecting rod 10,
10, the upper frame 5 is fixed to the lower surface of the cushion body 2, and the lower frame 6 is fixed to the upper surface of the base 3, respectively. By doing so, the cushion body 2 can be lifted diagonally upward with a single touch operation and rotated in an upright position, and when lowered, it can be tilted so that it can return to its original position.

Although a torsion bar is used in the link mechanism to apply a biasing force when the cushion body is raised and rotated, it is also possible to use a coil spring in combination for supplementary purposes. In addition, the width dimension of the base 3 is narrowed, and one side surface 3
A predetermined distance C may be provided in advance between A and the indoor corner wall surface _W1 in the longitudinal direction of the bed, and a working passage may be formed by lifting and rotating the cushion body 2. case,
If one side of the cushion body 2 that is not supported by the base 3 can be supported by the foldable auxiliary support leg 11, the cushion body 2 can be prevented from falling.

[Effect of idea]

As explained above, according to this invention, the cushion body of the bed body, which is installed in contact with both walls of an indoor corner, can be lifted diagonally upward and maintained in a floating state. The bed is separated so that there is a gap between the two, and the bed can be returned to the original contact state when the bed is lowered, making it easy to move the bed when cleaning or making the bed, improving work efficiency. At the same time, the bed height can be varied to minimize back fatigue of workers. In addition, the width of the base is made narrower than the width of the cushion body to create a gap between one side of the base and the corner wall, so that when the cushion body is lifted, a working passage is created between the entire bed and the corner wall. As a result, the efficiency of work such as indoor cleaning and bed making can be further improved.
