Abstract

A dual-purpose sofa bed for sitting and lying, which saves space. In order to improve the convenience and comfort of the dual-purpose sofa bed, the utility model discloses design into the cavity with the below of back, back case, cupboard, the bed has partly to get into "back + back case" or "back + cupboard" in the cavity of below when not using, and the part that exposes outside has constituteed a complete sofa with the back, when needing to use the bed, only need with the bed outwards pull out can. The beneficial effects are that: the space is saved, the whole thick mattress can be used, a proper elevation angle can be formed after the bed is changed into the sofa through the slope track, and bedding can be conveniently stored by utilizing the space behind the backrest.

Description

Dual-purpose sofa bed

Technical Field

A dual-purpose sofa bed for sitting and lying.

Background

The prior dual-purpose sofa bed adopts a folding mode, namely the bed is changed into the sofa by transversely folding or longitudinally folding, so that the dual-purpose sofa bed has two purposes and saves space, and the use convenience and the comfort are greatly sacrificed. Firstly, the whole thick mattress cannot be used by adopting a folding mode, which sacrifices the comfort of the bed; secondly, when the sofa is used, the seat surface is horizontal without elevation angle, which sacrifices the comfort of the sofa; furthermore, because of the folding, bedding articles such as fitted sheets and mattresses cannot be used as sofas as well, and the operations of bedding and rolling the bedding are very cumbersome and time consuming each time the bedding is switched between a bed and a sofa. Therefore, the conventional dual-purpose sofa bed can be used only for temporary emergency and is not suitable for long-term use.

Disclosure of Invention

In order to solve the problem that the prior dual-purpose sofa bed needs to greatly sacrifice the use convenience and the comfort, the utility model provides a scheme.

The utility model discloses the scheme that adopts is: the lower parts of the backrest, the backrest box and the cabinet are designed into cavities, when the bed is not used, one part of the bed enters the cavity below the backrest and the backrest box or the backrest and the cabinet, and the part exposed outside and the backrest form a complete sofa. When the bed is needed to be used, the bed only needs to be pulled out, and when the bed is not used, the sofa can be formed by pushing the bed inwards. In order to ensure that the bed has a proper elevation angle after being changed into the sofa and returns to the horizontal position after being changed into the bed by the sofa, the utility model discloses a slope track, the inboard footpost moves on the slope track, and the bed can change the angle in the moving process.

The utility model has the advantages that: 1, saving space. 2, a full thickness mattress can be used. 3, the bed can be changed into a sofa through the slope track, and the sofa has a proper elevation angle. 4, the space behind the backrest can be used for conveniently containing the bedding. 5, the bedding article on the bed can be used as a sofa without folding, and frequent bed laying and rolling are not needed. Because of the advantages, the utility model is suitable for long-term use.

Detailed Description

The bed must be moved in a lateral direction due to the length-width ratio of the bed. Two combinations can be used: one is a bed + back box (fig. 1) (fig. 2), and one is a bed + back + cabinet (fig. 3) (fig. 4). The main function of the backrest box is to support the backrest and have the function of storing articles, and the thickness of the backrest box is utilized to support the backrest, so that the cabinet can still exert the function of storing articles. The former combination only utilizes the space under the backrest and the thinner backrest box, so that the combined type backrest box is only suitable for a single bed; the latter combination utilizes a backrest and a thicker under cabinet space so that the hidden portion of the bed is increased and thus can be used in a double bed.

The backrest (1) is arranged on the front surface of the backrest box (2) or the cabinet (3) by hinges, and the hinges can be arranged below to lead the backrest to be opened downwards (figure 2) or above to lead the backrest to be opened upwards (figure 4). The quilt is more convenient to store after being opened upwards, the bed is pushed by only opening the backrest, the quilt pillow is placed on the inner side of the bed, and the backrest is put down (figure 3) (figure 4), but the support rod (4) is required to be installed after being opened upwards. If the backrest is downward, the backrest box (2) can be provided with a bottom plate which can bear objects, so that the bed can move more freely.

The inner side legs are shorter, and the inner side caster wheels (5) move on the slope tracks (6). The length of the slope track is approximately equal to the bed width and the seating depth, the gradient is approximately equal to the required sofa angle multiplied by the wheel distance between the inner foot and the outer foot/the track length, and the length difference between the inner foot and the outer foot is equal to the height of the outer dead point of the track. The outer stop point of the track is provided with a pit (7) to ensure that the bed can be relatively fixed and does not slide downwards.

When the bed, the backrest and the cabinet are combined, the cabinet is heavy, the span of two sides below the cabinet is large, and the height of the cabinet is also large, so thick plates or frames with inclined ribs are required to be adopted at the back and two sides, and the front of the cabinet is supported by thick cross beams and upright columns at two sides.

Claims

1. A dual-purpose sofa bed is characterized in that: a sofa backrest is arranged on the backrest box or the cabinet, a cavity is arranged below the backrest and the backrest box or the backrest and the cabinet, when the bed is not used, one part of the bed enters the cavity below the backrest and the backrest box or the backrest and the cabinet, the part exposed outside and the backrest form a complete sofa, and the bed is pulled out outwards to be used as the bed.
