Description

  The present invention relates to a sofa bed.

The backrest of a conventional sofa / bed is structured to move between a storage position near one of the long sides of the bed and a predetermined use position on the bed (for example, a patent) Reference 1 FIG. 4).

The conventional sofa-combined bed uses bedding cover means as a device to cover the bedding stored behind the backrest portion when converted to the sofa mode (for example, Patent Document 1 No. 8).
(See figure).

In the conventional sofa-combined bed, the long side of the backrest storage side is installed along the wall to shield the backrest in the storage state in the bed mode (for example, paragraph 0 of Patent Document 1).
025, see FIG. 2).

Since the sofa-combined bed has a movement distance between the storage position of the backrest portion and the use position, the movement of the backrest requires labor and labor. Moreover, the bedding cover used as a device for covering the bedding stored behind the backrest portion is visible. In addition, when the long side of the backrest storage side is installed along the wall, conversion from sofa mode to bed mode or from bed mode to sofa mode is not possible from the front, so between the sofa bed and the wall Requires a work space for moving the backrest, and in order for a person to move to the work space, a space is required for the person to move on either side of the pair of vertical panels of the sofa / bed. Therefore, there is a problem that the installation place of the sofa bed in the room is limited.

In order to solve such a conventional problem, the present invention provides a pair of left and right side panels according to claim 1, a top plate placed between the pair of left and right side panels, and one length of the top plate. A vertical panel provided vertically at the lower part of the side, and when it is converted to a bed state, it can be stored in a state of being close to the top plate below the top plate, and when converted to a sofa state, A backrest that is maintained on one long side of the plate and is movable to a predetermined use position on the bed member;
A backrest moving device that can be stored in a state where the backrest is tilted low toward the back side in the storage direction, and the backrest that is maintained in the use position with the vicinity of one long side stored in the lower part of the top plate. Provided is a sofa-use bed comprising a sofa-use bed portion that accommodates the backrest and cooperates to become a sofa while pulling out the vicinity of the one long side to be in a bed state. This solves the above problem.

According to the present invention, the bed portion includes a pair of left and right vertical members, a bed member provided between the pair of left and right vertical members, and a bed portion vertical provided on one long side of the bed member. The panel and the caster provided in the lower part of the bed member are provided.
The above-described problem is solved by providing the sofa combined bed described in 1.

The present invention is characterized in that, when converted into a sofa state according to claim 3, a storage is formed under the top plate behind the backrest, and the backrest also serves as a door of the storage. The above problem is solved by providing the differential fur combined bed according to claim 1 or claim 2.

According to the present invention, as the means for converting from the bed state to the sofa state or from the sofa state to the bed state, the pair of left and right side panels has a bed portion positioning that restricts the movement of the bed portion serving as the sofa. A mechanism is provided, a runner is provided on the backrest, a rail and a fixing plate are provided on the pair of left and right side panels, and the runner is incorporated in the rail so that the backrest can be moved or maintained from the front. The above-mentioned problem is solved by providing the sofa-use bed according to any one of claims 1 to 3, characterized by comprising a device.

When converting into a bed state, the backrest is stored in the lower part of the top board from the front, so that the movement distance of the backrest is short, and the labor and labor of conversion are reduced. Further, when converted to the sofa state, a storage is formed under the top plate behind the backrest, and the backrest serves as a door of the storage and the bedding can be stored while being shielded by the storage. Since the backrest can be moved from the front, the installation place of the sofa bed of the present invention in the room is free.
