Background

Storage and comfort are emphasized in modern residential environments. In some densely populated cities and countries, storage and organization has not been limited solely to everyday appliances. And more because some living environments are not very abundant now, so that living areas are very compact. Therefore, people usually arrange their living environment better in a limited space. The bed is one of the essential household articles for people in the family life. However, beds typically have a large footprint and often occupy a very substantial amount of living space.

In order to improve the reasonable usable area, a larger activity space is obtained by improving the use mode of the bed. Therefore, the sofa bed is formed. The sofa bed enables people to obtain larger living activity space through the mutual conversion between the sofa and the bed, greatly improves the space utilization rate, and enables people to enjoy more comfortable living environment in the limited space.

According to the sleeping habit, people usually sleep on their sides in the direction of the safe side, i.e. the backrest, so that the sleeping contact part (i.e. the bed frame) is hidden and separated from the position where the human body sits when the sofa is used (i.e. the sofa seat frame), thereby meeting the sanitary requirement of normal sleeping. On the other hand, as shown in fig. 5: the design that the width of the cushion is consistent with that of the armrests is realized, the gap 9 between the mattress and the armrests in the conventional sofa bed is eliminated, the injury of children or the damage of the mobile phone wallet falling into the gap are avoided, and the safety is improved.

In addition to satisfying the function of the side-lying sofa bed, as shown in fig. 6: the product is used as a double-person sofa, and the sofa can be used as a single-person sofa and a corner sofa to realize the lying function, the sofa seat frame becomes a leg rest position 10 after being stretched, and the bed frame is lifted to become a cushion position 11.

In order to solve the technical problem, the invention is realized as follows:

the utility model provides a sofa bed iron stand mechanism which characterized in that: the sofa comprises a sofa seat frame, a bed frame, a flat plate, a connecting rod, a first parallelogram mechanism and a second parallelogram mechanism, wherein the bed frame is positioned at the lower part of the sofa seat frame, the first parallelogram mechanism and the second parallelogram mechanism are respectively arranged at two sides of the sofa seat frame and the bed frame, a sofa mounting plate connected with the sofa seat frame is arranged on the first parallelogram mechanism, a bed frame mounting plate connected with the bed frame is arranged on the second parallelogram mechanism, the end parts of the connecting rods at two sides of the first parallelogram mechanism and the second parallelogram mechanism are respectively movably connected on one flat plate, and linkage rods are respectively connected between two sides of the first parallelogram mechanism and two sides of the second parallelogram mechanism and are mutually linked.

The sofa bed iron frame mechanism is characterized in that: the sofa bed further comprises anti-torsion mounting pieces which are respectively mounted on the second parallelogram mechanisms on two sides of the sofa seat frame and the bed frame.

The sofa bed iron frame mechanism is characterized in that: the left and right anti-torsion mounting pieces are connected by a wood board or a metal rod.

The sofa bed iron frame mechanism is characterized in that: the power spring is arranged between the connecting rods of the first parallelogram mechanism through the spring hanging pieces.

The invention has the beneficial effects that: the front frame is translated, extended and folded through two parallelograms and an opposite quadrilateral mechanism, and the rear frame correspondingly ascends and descends at the same time, so that the front frame is easy and convenient to open and fold and is in place in one step; the movement processes of the two sides can be synchronized through the anti-torsion mounting pieces, and the purpose of smooth opening and closing is achieved; the left and right anti-torsion mounting pieces are connected by a wood board, and can be sized automatically when in soft package without being limited by an iron frame; in the motion process of the mechanism, the power-assisted spring is stretched to generate power assistance, so that the burden of a user in the use process is reduced, and the whole opening and closing process is easier.

Detailed Description

As shown in fig. 1-4: a sofa bed iron frame mechanism comprises a sofa seat frame 1, a bed frame 2, a flat plate 12, a connecting rod 13, a first parallelogram mechanism 3 and a second parallelogram mechanism 4, wherein the bed frame is positioned at the lower part of the sofa seat frame, the two sides of the sofa seat frame and the bed frame are respectively provided with the first parallelogram mechanism and the second parallelogram mechanism, the first parallelogram mechanism is provided with a sofa mounting plate 5 connected with the sofa seat frame, the second parallelogram mechanism is provided with a bed frame mounting plate 6 connected with the bed frame, the end parts of the connecting rods at the two sides of the first parallelogram mechanism and the second parallelogram mechanism are movably connected on one flat plate to form an opposite sex quadrilateral mechanism 14, and the two sides of the first parallelogram mechanism and the second parallelogram mechanism are respectively connected with a linkage rod and are mutually linked.

Further, the sofa bed further comprises anti-torsion mounting pieces 7 which are respectively mounted on second parallelogram mechanisms on two sides of the sofa seat frame and the bed frame; the left and right anti-torsion mounting pieces are connected by a wood plate; the invention is divided into a left part and a right part which are arranged on two sides of a wooden frame of a sofa for matching use, under the common condition, if the width of the sofa is too large, the two sides are easy to be unevenly stressed, the motion state is asynchronous, and the motion smoothness is further influenced, therefore, the anti-torsion mounting piece is designed, the motion synchronism of the two sides is greatly improved through the wood plate, meanwhile, the connecting wood plate is used instead of the connecting iron pipe, so that a client can be automatically sized when in soft package, the limitation of the iron frame is avoided, and the production flexibility is greatly increased.

Further, the power spring is arranged between the connecting rods of the first parallelogram mechanism through a spring hanging piece, and the power spring 8 is arranged between the connecting rods of the first parallelogram mechanism; the invention is suitable for lying type and lying type sofa beds at the same time, the sofa bed frame of the lying type sofa bed generally has larger weight, and the load is larger only by manpower driving, therefore, the booster spring is designed, the booster spring is connected with the parallelogram 1 through the spring hanging sheet, when the sofa bed is in an opening state (bed shape) and a folding state (sofa shape), the spring is in a maximum stretching state, the tension is maximum at the moment, and when the sofa bed is in a middle state, the spring is in a minimum stretching state, therefore, in the movement process, the booster is provided, and the sofa bed is easier to open and fold.

When in the folded state, the bed frame mounting plate descends, and the bed frame is hidden under the sofa seat frame, namely the sofa shape; the sofa seat frame is pulled up manually to drive the sofa mounting plate and further drive the first parallelogram to move, the sofa seat frame is kept horizontal all the time and moves from the inner side to the outer side (middle state), meanwhile, the first parallelogram mechanism 3 drives the special-shaped quadrilateral mechanism 14 to move and further drive the second parallelogram mechanism 4 and further drive the bed frame mounting plate and the bed frame to lift, and finally the bed frame and the sofa seat frame are aligned to form a bed surface, namely an open state (bed shape);

when the sofa is in an open state, the sofa mounting plate is horizontally moved and extended, the bed frame mounting plate is lifted along with the sofa mounting plate, and the bed frame is parallel and level to the sofa seat frame, namely the bed shape is formed. Wherein, an anti-torsion mounting piece is also designed to play a role in coordinating the synchronism of the left mechanism and the right mechanism. In addition, in the movement process, the spring is stretched through the mechanism to provide assistance for the spring, so that the use process is easier.
