Folding Bed with Stretchable Supporting Legs

The present disclosure relates to the technical field of folding beds, and in particular, to a folding bed with stretchable supporting legs.

In current life and working scenarios, folding beds are widely used as flexible and convenient furniture in a plurality of fields, such as a home backup bed and medical care equipment and appliances.

Chinese utility model patent No. CN211748299U discloses an integrated folding bed, which includes a bed body, bed legs, and a bed frame. The bed body is formed by serially connecting a plurality of main bed plates that can be folded, and an expansion bed plate for widening is integrally arranged on a side surface of each main bed plate. The main bed plates and the expansion bed plates are connected by hinges. Two leaves of each hinge are fixedly mounted on upper surfaces of the main bed plates and upper surfaces of the expansion bed plates respectively. A pin of the hinge is upward.

The above folding bed has many problems that need to be solved urgently in practical use. For example, the bed legs are of fixed structures. When the expanded bed plates are used, an area of the bed body is significantly enlarged, and the bed legs in original fixing positions cannot be adjusted according to an area of the bed after expansion. Since the positions of the bed legs are not changed, a center of gravity of the bed body after expansion is shifted, and safety hazards such as shaking and overturning easily occur when a pressure is applied to the bed. This seriously affects the safety of use.

Therefore, a folding bed with stretchable supporting legs is provided.

The present disclosure aims to provide a folding bed with stretchable supporting legs, thereby solving or at least relieving one or more of the above problems in the prior art and problems of other aspects.

To achieve the above objectives, main technical solutions used by the present disclosure are as follows:

A folding bed with stretchable supporting legs includes a folding bed plate and bed leg assemblies. Two opposite sides of the folding bed plate are hinged with expansion bed plates. The bed leg assemblies are arranged at two ends of a bottom of the folding bed plate.

Each bed leg assembly includes a square tube. Adjustment rods are slidably plugged into two ends of the square tube. A supporting leg is fixedly mounted at one end of each adjustment rod away from the square tube through a bolt. A U-shaped elastic sheet is arranged inside each adjustment rod. Fixed ends of the U-shaped elastic sheets are fixedly connected to inner walls of the adjustment rods. Clamping heads are formed at movable ends of the U-shaped elastic sheets. A plurality of adjustment holes are provided in one side of each square tube. The clamping heads are able to be clamped into the adjustment holes.

In the folding bed with the stretchable supporting legs according to the present disclosure, the folding bed plate includes a first hip bed plate, a second hip bed plate, a leg bed plate, a bed-end bed plate, and a head bed plate. One side of the first hip bed plate is hinged to the head bed plate, and another side of the first hip bed plate is hinged to the second hip bed plate. One side of the second hip bed plate away from the first hip bed plate is hinged to the leg bed plate; and one side of the leg bed plate away from the second hip bed plate is hinged to the bed-end bed plate.

In the folding bed with the stretchable supporting legs according to the present disclosure, the folding bed plate further includes a first electric push rod and a second electric push rod. One end of the first electric push rod is hinged to the head bed plate. An end portion of a piston rod of the first electric push rod is hinged to the first hip bed plate. One end of the second electric push rod is hinged to the leg bed plate. A piston rod of the second electric push rod is hinged to the second hip bed plate.

In the folding bed with the stretchable supporting legs according to the present disclosure, each bed leg assembly further includes a connecting rod. One end of the connecting rod is fixedly connected to the square tube. One end, away from the square tube, of the connecting rod in one bed leg assembly is fixedly connected to the first hip bed plate. One end, away from the square tube, of the connecting rod in the other bed leg assembly is fixedly connected to the second hip bed plate.

In the folding bed with the stretchable supporting legs according to the present disclosure, a connecting plate is hinged to the connecting rod fixedly connected to the second hip bed plate, and another end of the connecting plate is hinged to the bed-end bed plate.

In the folding bed with the stretchable supporting legs according to the present disclosure, two connecting rods are arranged in each bed leg assembly, and the two connecting rods are fixedly connected to two ends of the square tube.

The present disclosure at least has the following beneficial effects:

According to transversely stretchable structures of the bed leg assemblies, a distance can be adjusted according to states of the expansion bed plates. With the two connecting rods, the stability is improved, thereby ensuring that the folding bed is stable and reliable in different usage states. This effectively disperses a pressure and avoids structural deformation.

The parts of the folding bed plate are hinged and connected, and can be folded and fitted during storage, thereby greatly reducing the volume. The transverse extension and contraction of the bed legs also help to reduce a storage space, facilitate storage and transportation, and adapt to various space scenarios.

Due to the electric push rods, angles of the bed plates can be flexibly adjusted to meet different body posture requirements such as sitting, lying down, and half-sitting and improve the comfort level of use. Due to the hinged design for the connecting plates and the bed-end bed plate, tilting angles of the legs of a user can also be adjusted, to further optimize a user experience.

Meanwhile, an occupied space can be saved by shortening the bed leg assemblies, thereby saving transportation costs.

The implementations of the present disclosure will be explained in detail below in conjunction with the accompanying drawings and embodiments, so that an implementation process of how to solve the technical problems using the technical means and achieve the technical effects in the present disclosure can be fully understood and implemented.

Referring toto, an embodiment of the present disclosure provides a folding bed with stretchable supporting legs, including a folding bed plate and bed leg assemblies. Two opposite sides of the folding bed plate are hinged with expansion bed plates. The bed leg assembliesare arranged at two ends of a bottom of the folding bed plate. Each bed leg assemblyincludes a square tube. Adjustment rodsare slidably plugged into two ends of the square tube. A supporting legis fixedly mounted at one end of each adjustment rodaway from the square tubethrough a bolt. A U-shaped elastic sheetis arranged inside each adjustment rod. Fixed ends of the U-shaped elastic sheetsare fixedly connected to inner walls of the adjustment rods. Clamping headsare formed at movable ends of the U-shaped elastic sheets. A plurality of adjustment holesare provided in one side of each square tube. The clamping headsare able to be clamped into the adjustment holes.

When a transverse width of the folding bed needs to be adjusted, the adjustment rodsare pulled outwards, and the adjustment rodsslide inside the square tubes. In this case, the clamping headsof the U-shaped elastic sheetsare compressed to deform, and are separated from the current adjustment holes. After the adjustment rodsare pulled to appropriate positions, the U-shaped elastic sheetsrecover its elasticity, and the clamping headsare re-clamped into the adjustment holesat the corresponding positions, thereby fixing a transverse distance of the bed leg assemblies. Through this structure, distances between the bed legs can be flexibly adjusted according to an unfolded state of the expansion bed plates, thereby ensuring stability of the folding bed in different usage states.

In this embodiment, the folding bed plate includes a first hip bed plate, a second hip bed plate, a leg bed plate, a bed-end bed plate, and a head bed plate. One side of the first hip bed plateis hinged to the head bed plate, and another side of the first hip bed plateis hinged to the second hip bed plate. One side of the second hip bed plateaway from the first hip bed plateis hinged to the leg bed plate. One side of the leg bed plateaway from the second hip bed plateis hinged to the bed-end bed plate.

Due to the hinged connection between the bed plates, when the folding bed needs to be stored, the first hip bed plate, the second hip bed plate, the leg bed plate, the bed-end bed plate, and the head bed platecan be folded and fitted in sequence by rotating hinged parts, thereby reducing the volume of a bed body and facilitating storage and transportation. During use, the bed plates are unfolded to form a flat sleeping plane.

In this embodiment, the folding bed plate further includes a first electric push rodand a second electric push rod. One end of the first electric push rodis hinged to the head bed plate. An end portion of a piston rod of the first electric push rodis hinged to the first hip bed plate. One end of the second electric push rodis hinged to the leg bed plate. A piston rod of the second electric push rodis hinged to the second hip bed plate.

By controlling extension and contraction of the first electric push rodand the second electric push rod, angles of the bed plates can be changed. For example, when the folding bed needs to be adjusted to a backrest mode, the first electric push rodextends to push the first hip bed plateto rotate around the hinged part between the first hip bed plateand the head bed plate, thus forming an angle between the head bed plateand the first hip bed plate. Meanwhile, the second electric push rodcan appropriately extend and contract to adjust angles of the leg bed plateand the second hip bed plate, to meet different user needs, such as sitting, lying down, and half-sitting. In addition, during transportation, an occupied space can be saved by shortening the bed leg assemblies, thereby saving transportation costs.

In this embodiment, each bed leg assemblyfurther includes a connecting rod. One end of the connecting rodis fixedly connected to the square tube. One end, away from the square tube, of the connecting rodin one bed leg assemblyis fixedly connected to the first hip bed plate. One end, away from the square tube, of the connecting rodin the other bed leg assemblyis fixedly connected to the second hip bed plate.

The connecting rodsplay a role in connecting the bed leg assembliesto the folding bed plate. After the square tubesare fixedly connected to the first hip bed plateand the second hip bed plate, the bed leg assembliescan stably support the bed plates. When the angles of the bed plates are changed, for example, when the angles are adjusted through the electric push rods or are enlarged through the bed plates, the bed leg assemblieskeep synergistic movement with the bed plates through the connecting rods, to ensure stability of the overall structure and avoid separation between the bed legs and the bed plates or avoid shaking.

In this embodiment, a connecting plateis hinged to the connecting rodfixedly connected to the second hip bed plate, and another end of the connecting plateis hinged to the bed-end bed plate.

When tilting angles of the legs of a user need to be adjusted, the piston rod of the second electric push rodis controlled to extend. Since the bed-end bed plateis hinged to the connecting rodsthrough the connecting plates, as the piston rod of the second electric push rodextends, a hinged part between the bed-end bed plateand the leg bed plateis arched upwards to form an inverted V shape.

When a tilting angle of the head bed plateneeds to be adjusted, the piston rod of the first electric push rodis controlled to extend. As the piston rod of the first electric push rodextends, the head bed platerotates around a hinged point between the head bed plateand the first hip bed plate, so that one end of the head bed plateaway from the first hip bed plateis lifted up.

In this embodiment, two connecting rodsare arranged in each bed leg assembly, and the two connecting rodsare fixedly connected to two ends of the square tube.

The two connecting rodsare fixedly connected to the two ends of each square tuberespectively, thus enhancing stability of connection between the bed leg assemblyand the bed plate. When a pressure is applied to the bed body, the two connecting rodscan more uniformly transmit the pressure to the square tubeand the supporting legs, to avoid avoiding structural deformation or damage caused by the pressure being applied to a single point. Meanwhile, during the adjustment of the transverse spacing of the bed leg assembly, the two connecting rodswork synergistically to ensure that the bed leg assemblyalways maintains a good connection with the bed plates, thereby improving stability and reliability of the entire folding bed.
