Title:
LIFTABLE BED
Document Type and Number:
WIPO Patent Application WO/2019/184290
Kind Code:
A1
Abstract:
A liftable bed comprises a storage compartment (10), a bed board (30), and a lifting unit (20). The bed board (30) is disposed at an opening of the storage compartment (10) and can be horizontally raised or lowered by the lifting unit (20). The lifting unit (20) comprises a cylindrical body (21), a lifting rod (22), and a winding spring (40). The liftable bed has a simple structure, and allows users to remove or store an article from any angle of the storage compartment (10). Raising or lowering the bed board (30) does not cause articles on the bed to pile up, thereby eliminating the need to reorganize the articles. A spring component of the winding spring (40) is specially configured, such that the supporting force of the winding spring (40) gradually increases during descending of the bed board (30), thereby generating natural cushioning resistance, reducing a descending speed of the bed board (30), preventing damage to a surface of the bed due to the impact of the bed board (30) against the storage compartment (10) at an excessive speed, and preventing injury caused by the descending bed board (30).
