A transmission device of a hospital bed, the hospital bed includes a body, a head, and a bed end. The transmission device contains: a main motor, a connection rod unit, and a driver. The main motor is disposed on a bottom of the body and includes a socket. The connection rod unit includes a first fixing rod connected to the head and a second fixing rod connected to the bed end. The driver is mounted on the main motor and includes an accommodation space, a driving motor, a reducer, a power cable, and a drive shaft. The first case has a first coupling orifice, and the second case has a second coupling orifice. The power cable is connected between the socket and the driving motor so as to supply a power to the driving motor and to lift or descend the head and the bed end synchronously.

The present invention discloses a storage bed with a horizontally lifted bed board, comprising a bed body provided with a storage cavity, a bed board frame covering the bed body, parallelogram lifting mechanisms symmetrically arranged on two sides of the bed board frame, and driving devices, wherein the parallelogram lifting mechanisms are connected to inner side walls of the storage cavity and the bed board frame, and the driving devices drive the parallelogram lifting mechanisms to push the bed board frame to be horizontally lifted towards a footboard direction of the bed body. The parallelogram lifting mechanisms are utilized to push the bed board frame to be horizontally lifted towards the footboard direction of the bed body, so that the bed board frame is prevented from coming into collision against a headboard in a lifting process; it is unnecessary to take down bedclothes when articles are stored or taken.

A method and apparatus to adjust the angle of a surface is disclosed. The apparatus includes a measuring device having hardware components capable of generating a measurement of the position of the measuring device relative to the earth's gravity and circuitry capable of communicating the measurement to a controller and at least one electro-mechanical device capable of displacing the surface connected to the controller. The surface may be a bed and the present invention is particularly useful when the surface is a bed in a camper van. When the camper van is parked on a hill, the present invention provides a convenient method for making the bed inside the camper van level, or at an angle preferred by the user, for comfortable sleeping.

A bracket is provided for an adjustable bed base that distributes the load of an actuator across a moveable panel of the adjustable bed. The bracket is coupled to a moveable panel of the adjustable bed, and has a width that is greater than one-third the width of the moveable panel.

A sliding lounger comprises a seating portion having seating slats and seating spaces between the seating slats, a back support portion having back slats and back spaces between the back slats, the back slats being receivable within the seating spaces and the seating slats being receivable within the back spaces, and a foot support portion having foot slats and foot spaces between the foot slats, the foot slats being receivable within the seating spaces, and the seating slats being receivable within the foot spaces. The back portion and foot support portion move between an open position where the back and foot slats are not received within the seating spaces and a compact position where the back and foot slats are received within the seating spaces.

An improved furniture system, including methods of manufacture, is disclosed. The furniture may be a sofa or a bed, which is reduced to a minimum volume for transportation. A flexible foldable honeycomb structure is used in manufacturing a supporting structure, wherein the hexagonal shape of said structure is strong and stable and provides a high bearing capacity versus weight. The honeycomb structure is designed to be foldable and used for saving space and to be easier for delivery in a box that fits in a small car, wherein said structure used flaccid materials that are glued to each other in certain ways to open and close easily, and wherein the number of layers of the flaccid materials determines the expansion length of the structure.

An adjustable bed system includes a pair of side rails transversely spaced, longitudinally aligned and arranged parallel to each other; and a pair of lifting assemblies attached respectively to the pair of side rails for operably adjusting positions of at least one part of a bed. Each lifting assembly comprises a back lifting arm and a leg lifting mechanism; a bracket; and a back lifting actuator and a leg lifting actuator received in the bracket. Each actuator includes an activation member and a motor member engaged with the activation member for driving the activation member. The activation member of the back lifting actuator is engaged with the back lifting arm for operably adjusting the back lifting arm at desired back positions. The activation member of the leg lifting actuator is engaged to the leg lifting mechanism for operably adjusting the leg lifting mechanism at desired leg positions.

Disclosed are adjustable bars and structures having adjustable bars. An adjustable bar includes an inner bar, an outer bar and a locking/unlocking mechanism to control relative movement of the inner and outer bars. The locking/unlocking mechanism includes a locking pin to be selectively inserted into a restriction hole of the outer tubular bar and a restriction member of the inner bar, thereby selectively restricting relative movement of the inner and outer bars in at least one direction. The locking/unlocking mechanism also includes a feature to prevent accidental release of the locking pin from the restriction member. Structures having such adjustable bars are easy and safer to use.
