For convenience, certain terms may be highlighted, for example using italics and/or quotation marks. The use of highlighting and/or capital letters has no influence on the scope and meaning of a term; the scope and meaning of a term are the same, in the same context, whether or not it is highlighted and/or in capital letters. It will be appreciated that the same thing can be said in more than one way. Consequently, alternative language and synonyms may be used for any one or more of the terms discussed herein, nor is any special significance to be placed upon whether or not a term is elaborated or discussed herein. Synonyms for certain terms are provided. A recital of one or more synonyms does not exclude the use of other synonyms. The use of examples anywhere in this specification, including examples of any terms discussed herein, is illustrative only and in no way limits the scope and meaning of the invention or of any exemplified term. Likewise, the invention is not limited to various embodiments given in this specification.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It will be understood that when an element is referred to as being “on,” “attached” to, “connected” to, “coupled” with, “contacting,” etc., another element, it can be directly on, attached to, connected to, coupled with or contacting the other element or intervening elements may also be present. In contrast, when an element is referred to as being, for example, “directly on,” “directly attached” to, “directly connected” to, “directly coupled” with or “directly contacting” another element, there are no intervening elements present.

According to the invention, the wall-hugger adjustable bed system with power fans has at least following benefits.
All the bed components (i.e., the back lifting assembly 130, the leg lifting assembly 140, the platforms 161-164 and mattress on the platforms) are coupled with the second (upper) frame structure 120, and the upper frame structure 120 is equipped with four rollers 25 that are received in the C-shape steel structure of the first (lower) frame structure 110. When the back lifting actuator 132 operably pushes the back lifting bracket 135 to rotate, the pulling force of the pair of back support tubes 51 causes the upper frame structure 120 to slide back and forth in the C-shaped steel of the lower frame structure 110 through the rollers 25, thereby realizing the forward or backward movement of the top portion (i.e., the back lifting assembly 130, the leg lifting assembly 140, the platforms 161-164 and mattress on the platforms) of the adjustable bed system 100.
The leg lifting assembly 130 is equipped with the rollers 44 that are moveably disposed on the roller support member 15, which in one embodiment is welded to the lower frame structure 110. Since the rollers 44 are supported by the support member 15, which increases the strength of the bed system, even if the bed system is subjected to force/stress, no deformation will occur.
Opening holes in the back platform 161, the seat platform 162, and the leg platform 164 of the bed system for mounting the fans, and the air flow of the fans can be adjusted according to the needs of the user.
