Another lifting bed drives the lifting device of the steel beam through a counterweight which moves up and down on two upright posts, thereby lifting or lowering the bed. The steel beam of the lifting device has short service life and high maintenance cost due to the limitation of the material of the steel beam. And the counter weight and the two stand columns occupy the distance between the bed and the wall body, namely the position of the bed head, so that the bed does not have a bed head backrest, the comfort level of use is reduced, and the living experience of people is greatly reduced. If the bedside backrest is added, more space is occupied, so that the unobtrusive space is narrower.

Therefore, the existing lifting device has the disadvantages of complex lifting structure, inconvenient installation, high maintenance cost and incapability of manually lifting the device under the condition of no electricity. In addition, the weight of the bed body and people is not enough to be supported, and certain potential safety hazards exist.

The lifting device 1 according to a first preferred embodiment of the utility model is elucidated in the following description with reference to fig. 1 to 6 of the drawings of the present description. The lifting device 1 comprises a load-bearing platform 10 and two counterweights 20, and a lifting structure 30 for connecting the load-bearing platform 10 and the two counterweights 20. The bearing platform 10 is used for bearing a mattress L, so as to form a bed for people to lie down for rest. Two counterweights 20 are located on both sides of the load-bearing platform 10, respectively, and raise or lower the load-bearing platform 10 and the mattress L carried thereby by the lifting structure 30.

Can fall to a proper height when needed for people to lie down and rest. As shown in fig. 4. When not in use, the utility model can be lifted to a proper height, such as close to the ceiling H, so as to leave a space below the bearing platform 10, and further put other furniture, such as a sofa, so that people can work or receive passengers by using the sofa. As shown in fig. 5. Thereby improving the space utilization rate of the room and further greatly improving the living quality of the house of people.

As shown in fig. 1 to 3, in particular, the lifting structure 30 includes two columns 31, and the two columns 31 are respectively located at two sides of the load-bearing platform 10, for supporting the load-bearing platform 10, and the load-bearing platform 10 can move up and down along the two columns 31.

In this embodiment, two of the columns 31 are respectively provided at one end of the load-bearing platform 10 and are respectively mounted to the wall W. And further, the load-bearing platform 10 is more stably moved up and down along the two columns 31, and a space is provided between the load-bearing platform 10 and the wall W.

In another embodiment, one end of each of the two posts 31 is mounted to the ceiling H, and the other end is mounted to the floor V.

The lifting structure 30 further includes two first connectors 32 and two second connectors 33, and the two first connectors 32 are respectively mounted on the side surfaces of one end of the load-bearing platform 10. Two of the second connection members 33 are slidably connected to the corresponding ones of the columns 31, respectively, and each of the first connection members 32 is detachably connected to the corresponding one of the second connection members 33. Furthermore, the load-bearing platform 10 can be detachably connected to two of the uprights 31.

As shown in fig. 3 and 6, further, each of the first connecting members 32 has a long side 321 and a clamping end 322, the long side 321 is mounted on a side surface of one end of the load-bearing platform 10, each of the second connecting members 33 has a clamping groove 331 and at least two pulleys 332, and the clamping end 322 of the first connecting member 32 is detachably clamped in the clamping groove 331 of the second connecting member 33. So that each of the first connection members 32 can be detachably connected to the corresponding second connection member 33.

As shown in fig. 2, each of the columns 31 is provided with a chute 311, and the pulley 332 is slidably connected to the chute 311 of the column 31. So that the second connector 33 is slidably connected to the upright 31. The load-bearing platform 10 can then be detachably connected to two of the uprights 31 and can slide up and down along the two uprights 31. For later maintenance and replacement of the fitting.

As shown in fig. 1, the lifting structure 30 further comprises two chains 34 and two gears 35, each gear 35 being mounted to a corresponding one of the uprights 31, i.e. close to the ceiling H. Each of the chains 34 is toothed to one of the gears 35, and one end of each of the chains 34 is connected to one of the second links 33, and the other end is connected to one of the weights 20. When the gear 35 is driven by an external force, the chain 34 is rotated, and the load-bearing platform 10 and the counterweight 20 are lifted or lowered.

That is, when the counterweight 20 is raised, the load bearing platform 10 is lowered. When the counterweight 20 is lowered, the load bearing platform 10 is raised. I.e. the weight 20 is lifted or lowered by the same distance as the load bearing platform 10 is lowered or raised. In such a way that the counterweight 20 lifts or lowers the load bearing platform 10.

Further, the lifting device 1 further comprises at least one motor 40, and drives the gear 35 through a driving belt to further drive the chain 34 to rotate, so that the load-bearing platform 10 and the counterweight 20 are lifted or lowered.

In another embodiment, the motors 40 are implemented in two, for driving the two gears 35, respectively. Thereby making it easier to raise or lower the load bearing platform 10. In this embodiment, the motors 40 are synchronized. I.e. to drive the rotation of both said gears 35 simultaneously in order to raise or lower said load-bearing platform 10 smoothly.

In order that the two counterweights 20 do not shake when being raised or lowered, the two counterweights 20 are slidably disposed outside the two columns 31, respectively. That is, each of the counterweights 20 moves up and down along the corresponding column 31. Thereby avoiding safety problems caused by shaking of the weight 20 when it is raised or lowered.

Specifically, a rail 313 is provided on the outer side of each upright 31, that is, on the opposite side of the chute 311, the rail 313 is provided, and each counterweight 20 is provided with at least one slider 21, and the slider 21 is slidably connected to the rail 313. That is, the slider 21 is restricted to move up and down along the rail 313. So that each of the counterweights 20 moves up and down along the upright 31.

It should be noted that the total weight of the two counterweights 20 is approximately equal to the total weight of the load bearing platform 10 and mattress. Thereby avoiding the weight 20 from moving the load bearing platform 10 and mattress into position under its own weight. That is, when the total weight of the two counterweights 20 is greater than the total weight of the weight-bearing platform 10 and the mattress, the weight of the two counterweights 20 lifts the weight-bearing platform 10 and the mattress by losing the external force after the weight-bearing platform 10 and the mattress are lowered.

It will be appreciated that when the total weight of both of the counterweights 20 is less than the total weight of the load bearing platform 10 and mattress, the load bearing platform 10 and mattress cannot be stabilized. That is, when the load-bearing platform 10 and the mattress are lifted, the load-bearing platform 10 and the mattress are lowered under their own weight by losing the external force.

In order to enable the two counterweights 20 to move up and down more easily, the elevating structure 30 further includes two auxiliary gears 36 and two cross members 37, each of the cross members 37 integrally extending at right angles from the upright 31. That is, the cross member 37 and the upright are T-shaped. Each of the auxiliary gears 36 is mounted to the corresponding cross member 37, respectively, and each of the auxiliary gears 36 is disposed at a side-by-side interval from each of the gears 35, respectively. The chain 34 is toothed with the gear 35 and the auxiliary gear 36, and is connected at one end to one of the second links 33 and at the other end to one of the weights 20. That is, each of the chains 34 is bent twice and forms a right angle through the gear 35 and the auxiliary gear 36. In this way, the auxiliary gear 36 shares the gravity applied to the gear 35, so that the lifting device 1 is safer and smoother in lifting or falling.

When the load-bearing platform 10 is put down for a person to lie down and rest, the load-bearing platform 10 is unstable due to the total weight of the load-bearing platform 10 and the mattress, and the upright 31 receives a larger torsion force, particularly, the connection between the load-bearing platform 10 and the upright 31 receives a larger torsion force, so that the first and second connection members 32 and 33 are deformed by compression, and even damaged, to be unusable. Therefore, at least one supporting member 50 is disposed below the load-bearing platform 10, and when the load-bearing platform 10 is lowered and contacts with the supporting member 50, the supporting member 50 is used for supporting the load-bearing platform 10, thereby reducing the load of the load-bearing platform 10, making the load-bearing platform 10 more stable when in use, reducing the torsion force of the upright posts 31, and further prolonging the service life of the lifting device 1, so that people can feel safe when lying and resting, and there is no fear of crushing the lifting device 1.

Further, the support member 50 has a backrest 51 and two armrests 52, and a base 53, the backrest 51 is located at one side of the base 53, i.e., the side against the wall W, the two armrests 52 are located at both sides of the backrest 51 and the base 53, respectively, and are surrounded to form a sofa shape, and the base 53 can be placed with cushions for people to use as a sofa.

When the load-bearing platform 10 is lowered, the bottom of the load-bearing platform 10 is supported by the two armrests 52, and the load-bearing platform 10 is attached to the backrest 51. That is, the backrest 51 now exactly fills the distance between the load-bearing platform 10 and the wall W as a head of a bed, so that one can rest against the backrest 51.

Alternatively, the user may manually raise or lower the load bearing platform 10. That is, the user directly applies power to the load bearing platform 10, so that the load bearing platform 10 can be lifted or lowered.

It will be appreciated by persons skilled in the art that the embodiments of the utility model described above and shown in the drawings are by way of example only and are not limiting. The objects of the present utility model have been fully and effectively achieved. The functional and structural principles of the present utility model have been shown and described in the examples and embodiments of the utility model may be modified or practiced without departing from the principles described.
