Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a twin type bed apparatus.

[0002]

2. Description of the Related Art There are various types of bed devices such as a single type, a double type and a twin type, and when two people use the bed type, a double type or a twin type is selected.
Each of the double type and twin type has its own characteristics,
The twin type in which two beds are joined has an advantage that the movement of the user of one bed is less likely to be transmitted to the user of the other bed, so that the sleeping of each other is not hindered.

Further, since the two beds can be used as a single type by separating them from each other, for example, when one user gets sick, the two beds can be separated from each other to reduce the influence on the other user. There are advantages such as being able to do so, and attention is paid to these advantages, and the number of users is increasing.

By the way, in the conventional twin type bed apparatus, two single type beds are simply arranged side by side. As a result, the overall appearance of the bed apparatus as a single unit was not exhibited, and the product value could not be sufficiently increased.

Further, if the two beds are simply arranged side by side, it may take time and effort to join or separate the beds. Therefore, there is a bed in which casters are attached to each bed so that the moving operation of these beds can be performed relatively easily.

However, since casters with stoppers must be used in order to prevent the beds from moving when the bed is moved or in use, not only is the operation of the stoppers troublesome, but the operation is also difficult. If I forget, it sometimes slipped during use.

[0007]

As described above, in the conventional twin type bed apparatus, two beds are simply arranged side by side. Therefore, since the bed apparatus as a whole is not cohesive, the appearance is unsatisfactory and the commercial value of the twin type bed apparatus cannot be increased.

In order to facilitate the movement of the two beds or to make them immovable at a predetermined position,
If a caster with a stopper is provided, not only the operation of the stopper is troublesome but also each bed moves freely, which makes it difficult to use.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a twin type bed apparatus which has a good appearance and can regulate the movement of each bed more than necessary. To do.

Another object of the present invention is to provide a bed apparatus in which the bed can be moved by casters and the movement of the bed can be blocked without any special operation during use.

[0011]

According to a first aspect of the present invention, there is provided a board body having an open space on the front surface side, and the board body is arranged on the front surface side of the board body and is substantially orthogonal to the front surface. A front-rear movable body that is movable in the front-rear direction, a pair of left-right movable bodies that are provided in the front-rear movable body so as to be movable in the left-right direction that intersects the front-rear direction, and are connected to the left-right movable bodies. The pair of left and right movable bodies and the pair of beds provided so as to be interlocked with the movement of the front and rear movable bodies, the first regulation means for regulating the movement range of the front and rear movable bodies in the front and rear direction, and the left and right of the pair of left and right movable bodies. A second restricting means for restricting a moving range in the direction.

According to a second aspect of the present invention, in the first aspect of the present invention, the bed is connected to the left and right movable bodies so as to be movable in the vertical direction, and the bed is immovable due to a load. It is movably supported by the caster.

According to the first aspect of the present invention, the appearance of the pair of beds is integrated with the body of the board so that the appearance can be improved. Further, each bed is movable and its moving range is restricted. As a result, the pair of beds can be arranged according to the usage pattern, and the beds can be prevented from moving more than necessary.

According to the second aspect of the present invention, the bed movably supported by the casters becomes immovable when a load is applied, so it is not necessary to operate the bed so that it does not move during use.

When the beds 4 and 5 are not used, one end of the beds 4 and 5 can be inserted into the space 3 to effectively use the indoor space. In other words, even if the board body 1 is provided, it is possible to minimize the board body 1 occupying an extra indoor space when not in use.

The front-rear movable body 7 and the pair of left-right movable bodies 1
The movement range of 3 and 14 is regulated by the first stopper 16 and the second stopper 18. Therefore, these beds 4 and 5 do not move more than necessary, so that they are not only easy to use but also always have a good appearance as one bed apparatus.

The pair of beds 4 and 5 can be separately moved in the left-right direction, that is, in the contacting / separating direction, but they move together in the front-back direction by the front-rear movable body 7. Therefore, the pair of beds 4 and 5 can be set in the left-right direction without shifting their positions in the front-rear direction, so that the moving operation thereof is easy.

The casters 31 that movably support the frames 21 of the beds 4 and 5 are subjected to the above-mentioned frames when a load is applied.
It will support the frame 21 immovably. Therefore, in order to use the beds 4 and 5, the user needs to use the mattress 2
6 on each bed 4, depending on the load of the user,
5 becomes immobile. In other words, the beds 4 and 5 are movable when not in use, but are prevented from moving without any operation when in use, so that they can be prevented from moving when in use or can be moved when not in use. It is easy and convenient to use because the operation of is unnecessary.

[0043]

According to the first aspect of the present invention, the appearance of the pair of beds can be improved by presenting the appearance of being integrated with the board body, and the beds can be moved and the front, rear, left and right directions thereof can be obtained. By restricting the movement range of the bed, it is possible to prevent the bed from moving more than necessary, and thus it is easy to use. Moreover, an open space is formed on the front surface of the board body,
Since one end of a pair of beds can be put into and taken out of the above-mentioned space, the board body does not get in the way by pulling it out when it is in use, and it can be inserted effectively when it is not in use. be able to.

According to the second aspect of the present invention, since the pair of beds are movably supported by the casters, not only the beds can be easily moved according to the usage pattern, but also the casters apply a load to the beds. It becomes impossible to move. Therefore, there is no need to operate the bed so that it does not move when it is used, or so that it can move when it is not in use, and it is easy and convenient to use.
