Description

Electric bed

Technical field

The invention relates to a bed, in particular to an electric bed.

Background technique

With the gradual improvement of people's living standards, people's attention to sleep quality is increasing. As a result, beds for ensuring and improving the quality of sleep have been developed in recent years, in particular moving beds, in particular electric beds driven by drive means such as electric motors.

The moving bed and the electric bed derived from the medical bed have not been used for the sleeping bed of the general public for a long time due to their complicated structure, high cost, and unsuitable appearance for home use. With the development of technology and the optimization of design, an electric bed with a relatively simple structure has also been designed on the market. This type of electric bed has the following features, including:

- basic bed frame, its horizontal setting;

At least one movable sub-frame pivotally coupled to the base frame for rotation between a horizontal position and a raised position;

a drive device capable of driving rotation of the at least one movable sub-frame;

- a plurality of independent bed plates comprising at least one fixed bed plate and at least one movable bed plate, the plurality of bed plates being interconnected by hinges and then fixed to the base bed frame and the movable sub-frame.

The electric bed has a relatively simple structure and can provide a basic bed lift function. However, such electric beds are usually assembled and packaged in advance at the factory and then shipped to the customer. In this process, packaging and transportation, especially for transnational shipping, requires a bed package The equipment is as small as possible so that it can be loaded into the container container and can be easily transported to the ordinary elevator when transported to the customer. However, these demands are currently not well met by factory pre-assembled electric beds. Especially when the whole bed is too large, it will cause some transportation companies, such as UPS, to refuse to carry, and will be unable to be transported to the customer through ordinary elevators, requiring additional labor and lifting machinery. These will increase the customer's final cost of use and will also result in a decline in the customer experience.

Summary of the invention

To this end, the object of the present invention is to overcome one or more of the disadvantages that have been discovered in the prior art.

For this purpose, an electric bed is proposed according to the invention, which is achieved by the following technical solution:

The intermediate longitudinal members 24, 24' are arranged parallel to each other and are vertically connected to the intermediate cross members 23, 23' in the plane P of the frame, for example by welding, riveting or the like. Further, they are arranged substantially in the middle of the frame, the function of which will be described later.

The movable sub-frame includes a head frame 31 and a leg frame 32 which are substantially rectangular frames, one side of which is rotatably coupled to the base frame, and the joints are adjacent to the intermediate cross members 23, 23', respectively. The head frame 31 and the leg frame 32 are rotatable between a horizontal position and a raised position, wherein in the horizontal position, the head frame 31 and the leg frame 32 are substantially parallel and located on the plane P, or have a small upward offset . In the raised position, the head frame 31 and the leg frame 32 are lifted up to form a certain angle with the plane P, for example, 0-60 degrees.

Drive means, such as

pusher motors

61 and 62 as shown in Figures 1 and 2, which pass the drive means of the respective ends, such as

ear climbing members

51, 52, 53, 54 respectively, respectively with the base bed frame 2 The intermediate longitudinal members 24, 24' and the

movable sub-frames

31 and 32 are rotatably coupled. With this arrangement, the telescopic operation of the push rod motor push rod can drive the rotation of the

movable sub-frames

31 and 32 so that the latter can move between the horizontal position and the raised position.

Further, the driving device fixing members, such as the

ear climbing members

51, 52, 53, 54 as shown in FIG. 4, are generally triangular rigid fixing pieces, one side of which is fixed to the foundation by nuts, welding, riveting, and the like. On the bed frame or the movable sub-frame, the apex opposite to the fixed side has a fixing hole through which the end of the push rod motor is rotatably connected, for example, in the form of a pin and a spring card.

The electric bed also includes a plurality of quick loading devices that are respectively disposed on the base bed frame 2 and the movable sub-frame. As shown in FIGS. 1 and 2, the quick loading device 40 is disposed on the rotating shaft side of the movable sub-frame 31, and the quick loading device 40 is disposed on the rotating shaft side of the movable sub-frame 32. The

quick loading devices

41 and 42 are disposed on the cross members 23, 23' of the base frame 2.

As shown in Fig. 1, there are four independent bed plates, namely a head bed plate 11, a waist bed plate 12, a leg bed plate 13, and a foot bed plate 14. Optionally, the bed panels are wood panels or conforming panels with wood grain paper. The head deck 11 is placed on the movable sub-frame 31 and connected thereto by the block device 40 so that the head deck 11 can be rotated together with the movable sub-frame 31. Similarly, the leg deck 13 is placed on the movable sub-frame 32 and connected thereto by the quick-release device 40 so that the leg deck 13 can be rotated together with the movable sub-frame 32.

Wherein, the first arrangement is as shown in FIG. 1 and FIG. 2, one end of which is rotatably connected to the leg bed plate 13 through the additional quick-

loading devices

44, 45, and the other end is connected to the basic bed frame. The connected rotating members 50 are connected. In this arrangement, the rotation of the leg deck 13 can cause the flip of the foot deck 14. The second arrangement is not shown in the figures, wherein the foot deck 14 is secured to the base bed frame 2 by additional quick-loading means 44, 45, such as the fixed attachment of the waist deck 12 to the base bed frame 2. In this arrangement, the rotation of the leg deck 13 does not cause the flip of the foot deck 14.

It should be pointed out that these independent bed plates can be transported separately from the bed frame, so that the electric bed can be transported to the customer through a smaller package volume, and then the customer can assemble it by himself. Assembled quick-loading device.

Further, as shown in FIG. 3, the quick-loading device may be, for example, a channel-shaped member having a notch shape complementary to the shape of the edges of the plurality of bed plates to facilitate fixing the plurality of bed plates in the slots. Inside the mouth member. In the example shown, the notch section is C-shaped and is arranged to complement the cross-sectional shape of the edge of the deck. The channel member has a bottom surface and two sides that are substantially parallel and perpendicular to the bottom surface, wherein the free sides of the two sides are disposed adjacent to each other so as to be in contact with the edge of the bed when the bed plate is inserted into the slot When the bottom surface of the channel member is abutted, the two sides of the slot have a fixing force for clamping the bed plate to facilitate quick fixing of the bed plate in the channel member.

Preferably, the overall length of the channel member is at least half of the length of the corresponding edge of the bed, and the width of the bottom surface is slightly larger than the thickness of the corresponding bed plate, and the width of the two sides is greater than the width of the bottom surface, preferably the width of the bottom surface. More than 1.5 times so as to provide better gripping effect.
