Abstract

The invention relates to a sofa bed without movable supporting legs, which comprises a fixed framework, a movable framework, a bearing type sliding rail and an angle brace. The method is characterized in that: the fixed framework and the movable framework are connected through the bearing type sliding rail. And one end of the corner connector is connected with the fixed framework. This sofa bed has abandoned the restraint that the activity skeleton of traditional sofa bed needs the supporting leg, has only kept the most basic supporting leg of non-activity skeleton part, under the prerequisite of guaranteeing enough security, and the step is still less, the action is more laborsaving when letting the sofa warp to the bed, also lets the sofa structure simpler, and the outward appearance is more slim and graceful.

Description

Sofa bed without movable supporting legs

Technical Field

The invention relates to the technical field of furniture, in particular to a sofa bed without movable supporting legs.

Background

When the existing sofa bed is transformed into a bed, the movable framework part needs to be provided with a supporting foot standing on the ground to play a supporting role, and the supporting foot is divided into an explicit upright column type, an explicit upright column type with rollers, an implicit folding upright column type and an implicit hinged rod linkage type. Explicit column type can harm the floor in the pull, and explicit area gyro wheel column type is the installation pulley below the supporting legs of column type, makes sofa bed pull more convenient, also is not fragile and hinders the floor, nevertheless can not fold, and inconvenient hiding is also not pleasing to the eye. The hidden folding upright column type can be folded to enable the feet to be parallel to the ground when in a sofa state, the hidden folding upright column type is tightly attached to the sofa to play a hidden effect, when the hidden folding upright column type is deformed into a bed, the folding feet are folded for 90 degrees and are perpendicular to the ground, the effect of supporting the movable framework is played, and the folding feet need to be manually folded, so that the hidden folding upright column type is troublesome to use and difficult to operate. The hidden type hinged rod linkage type is that when the movable framework deforms, the folding legs are automatically turned over through the hinged rods, and the supporting legs of the hidden type hinged rod linkage type are weak in supporting force and not firm enough. No matter the display or the hidden type, the idea that the support is supported by the supporting legs cannot be got rid of, the structure is complex, and the operation is inconvenient.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the sofa bed without the movable supporting legs, the sofa bed has the advantages that the conventional scheme that the movable framework is supported by feet is greatly abandoned, only the supporting legs of the non-movable framework part of the sofa are reserved, the structure of the sofa bed is simpler and the use is more convenient on the premise of keeping enough supporting force, and the sofa bed is better balanced between the simple structure and the practical structure.

In order to achieve the purpose, the invention adopts the following technical scheme:

a sofa bed without supporting legs comprises a fixed framework, a movable framework, a bearing type sliding rail and corner connectors. The method is characterized in that: the fixed framework and the movable framework are connected through the bearing type sliding rail. The corner connector is connected with the fixed framework.

The fixed framework specifically comprises a seat frame, fixed legs, a leaning frame, a connecting plate and a triangular connecting piece. The front end of the connecting plate is connected with the top end of the leaning frame, and the bottom end of the leaning frame is connected with the sofa seat frame. The fixed legs are arranged below the seat frame. A right-angle side of the triangular connecting piece is fixed with the lower surface of the connecting plate, and the other right-angle side of the triangular connecting piece is fixed with the back surface of the leaning frame.

The angle code is an L-shaped bearing type angle code, one side of the angle code is fixed on the connecting plate, and the other side of the angle code is fixed on other load-bearing objects. The bearing type corner brace is thick and solid in material and tough in texture.

The load-bearing object can be a wall body or a cabinet body.

The bearing type slide rail comprises an outer rail and an inner rail. The outer rail is fixed on the sofa seat frame, and the inner rail is fixed on the movable framework. The bearing type slide rail is thick and solid in material and tough in texture.

The invention has the beneficial effects that:

1. is firm and durable.

2. The structure is simple and elegant, and the design integration can be achieved by ingeniously combining the structure with other heavy objects such as walls and cabinets.

3. When the supporting legs are deformed, redundant actions are not needed to be applied to the supporting legs, and the use is convenient.

Detailed description of the invention

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and not for limiting the present invention, and those skilled in the art can make modifications without inventive contribution to the present embodiment as needed after reading the present specification, but all of which are protected by patent law within the scope of the claims of the present invention.

As shown in figures 1-4, a sofa bed without supporting legs comprises a fixed frame, a movable frame, a bearing type slide rail and a corner brace. The method is characterized in that: the fixed framework and the movable framework are connected through the bearing type sliding rail. One end of the corner brace is fixed on the fixed framework. This embodiment uses a three-position sofa bed.

As shown in fig. 1, the fixed framework of the sofa specifically includes a seat frame 1, a backrest frame 2, fixed legs 3, a connecting plate 4, and a triangular connecting piece 5. The front end of the connecting plate 4 is connected with the top end of the leaning frame 2, and the bottom end of the leaning frame 2 is connected with the sitting frame 1. Four fixed legs 3 are under the seat frame. A right-angle side of the triangular connecting piece 5 is fixed with the lower surface of the connecting plate 4, and the other right-angle side is fixed with the back surface of the leaning frame 2.

As shown in fig. 2, the corner brace is a corner brace connecting part, the corner brace is an L-shaped load-bearing type corner brace 6, one side of the corner brace is fixed on the connecting plate 4, and the other side of the corner brace is fixed on other load-bearing objects. The bearing type corner brace is thicker and firmer in material and tougher in texture. In the embodiment, four corner connectors are installed, one connecting plate is arranged at the corresponding position of the left side and the right side of the sofa, and one connecting plate is arranged at the corresponding position of the two sides of the middle seat.

As shown in fig. 3, the other load-bearing objects can be walls or cabinets.

3-1 indicates that the other load bearing object may be a wall when the sofa is placed against a wall.

3-2, when the sofa is not placed against a wall, the other bearing objects can be cabinets such as a locker, a wine cabinet, a bookcase and a dining cabinet.

As shown in fig. 4, the load-bearing slide rail includes an outer rail 8 and an inner rail 9. The outer rail 8 is fixed at the seat frame 1, the inner rail 8 is fixed at the movable framework 7, and the bearing type sliding rail is thicker in material and tougher in texture. In the embodiment, two sets of load-bearing type sliding rails are installed on each seat, and six load-bearing type sliding rails are installed in total.
