Description

Sofa bed without movable supporting legs

Technical Field

The utility model relates to the technical field of furniture, concretely relates to sofa bed that does not need 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

The utility model provides a not enough to prior art exists, the utility model provides a need sofa bed of activity supporting legs, this sofa bed, courage have abandoned the conventional scheme that supports movable skeleton with the foot, have only remain the supporting leg of sofa non-activity skeleton part, under the prerequisite of keeping the sofa not loose the frame and toppling over, make sofa bed structure simpler, it is more convenient to use, reaches better balance between simple and practical between the two.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a sofa bed without supporting legs comprises a fixed framework, a movable framework, a bearing type slide rail, screws and a bearing weight; the method is characterized in that: the fixed framework is connected with the movable framework through the bearing type sliding rail; the load-bearing objects include but are not limited to walls, cabinets and the like; the screw is connected with the fixed framework and the weight bearing object.

Preferably, the fixed framework specifically comprises a seat frame, fixed legs, a backrest frame and a threading belt; the fixed legs are positioned below the fixed framework; the leaning frame is positioned behind the seat frame; the threading belt is connected to the rear of the leaning frame.

Preferably, the connection mode of the threading belt and the leaning frame includes, but is not limited to, mortise and tenon, hardware, or the combination of mortise and tenon and hardware, and the like.

Preferably, the screw connection threading belt is connected with the load bearing object.

Preferably, the screw can be screwed into the leaning frame firstly, and is connected with the leaning frame, the threading belt and the load bearing object together.

Preferably, the load-bearing sliding rail comprises an outer rail and an inner rail; the outer rail is fixed on the seat frame, and the inner rail is fixed on the movable framework.

Preferably, the load-bearing slide rail is made of thicker and tougher materials.

Preferably, the screws include, but are not limited to, expansion screws, self-tapping screws, and the like.

The utility model has the advantages that:

1. the bearing type slide rail is connected with the fixed framework and the movable framework, so that the movable framework cannot deform, fall off or be scattered.

2. The fixed framework and the weight are connected through the screws, so that the fixed framework can further resist torsion, and the sofa bed can be prevented from being tilted, inclined and turned over.

3. The wearing belt can prevent the deformation of the leaning frame, and more importantly, the contact area between the screw and the sofa bed is increased, so that the screw can be connected with the sofa bed more firmly.

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 to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

As shown in fig. 1-3, a sofa bed without supporting legs comprises a fixed frame, a movable frame 7, a bearing type slide rail, a screw 6 and a bearing 5; the method is characterized in that: the fixed framework is connected with the movable framework 7 through the bearing type sliding rail; the load-bearing object 5 comprises but is not limited to a wall, a cabinet and the like; the screw 6 is connected with the fixed framework and the bearing 5.

As shown in fig. 1, the fixed framework of the sofa specifically includes a seat frame 1, a backrest frame 2, fixed legs 3, and a strap 4. The leaning frame is positioned at the back of the fixed framework; the four fixing legs are positioned at the bottom of the fixing framework; the threading belt 4 is positioned at the back of the leaning frame. In the embodiment, three threading belts 4 are arranged, and the threading belts 4 are fixed with the leaning frame 2 through screws.

In the embodiment shown in fig. 2, the load carrier 5 is a wall. The screw 6 in the embodiment described is an expansion screw. In the embodiment, six screws 6 are provided, and two screws are fixed on each threading belt. The expansion screw is divided into an expansion pipe and a screw rod, and the expansion pipe is embedded into the wall body of the weight bearing object 5. In the embodiment, the screw 6 is used for expanding the screw, the screw rod of the screw is firstly screwed into the leaning frame, then passes through the threading belt and is finally screwed into the wall body. Together with the leaning frame, the threading belt and the wall body of the load-bearing object 5 are connected and fixed. Therefore, the fixed framework is firmly connected with the load-bearing object and is not easy to tilt, incline or turn over.
