Abstract
An adjustable bed is provided that includes a bed frame defined by a pair of side rails, a rear rail, and a front rail. A mattress support is disposed on top of the bed frame and includes a plurality of support panels, coupled in succession using hinges such that at least one support panel can be articulated, causing the panel to pivot about the hinge connection with an adjacent panel. An adjustment mechanism is provided that includes torque tubes that each include a torque shaft and lift links. The torque tubes are removably attachable to the side rails of the bed frame by inserting bushings on the ends of the torque shafts into slots running along the insides of the side rails. A motor is coupled to the torque tubes, locking the torque tubes in place. A set of foot links is provided for supporting a foot panel during articulation of an adjacent leg panel.
Description
- Adjustable beds are a versatile alternative to conventional beds because they allow the user to position the bed according to various configurations. Typically, adjustable beds allow for at least the head and foot of the bed to be raised and lowered. In adjustable beds, the mattress typically rests on a mattress support that consists of three or four support panels. The support panels are arranged end-to-end and each panel is pivotably connected to adjacent panels using hinges. For example, in the case of a four-section mattress support, the adjustable bed includes a head support panel, a center support panel, a leg support panel, and a foot support panel. The support panels are connected such as to allow pivotal movement between adjacent panels about parallel axes transverse to the length of the bed.
- Adjustable beds are typically quite heavy and include a fair amount of hardware, particularly as part of the adjustment mechanisms. Much of the hardware on most adjustable beds is interconnected and requires appropriate experience and tools to assemble. Accordingly, adjustable beds are often shipped partly pre-assembled as one large and heavy package and often must be assembled for a user by a service technician. Moreover, adjustable beds typically include shrouds or other types of covers to hide the operational hardware from view so that an appealing aesthetic appearance can be maintained.
- The invention is defined by the claims below. This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
- Embodiments of the present invention relate to an adjustable bed with a break-down feature that allows the adjustable bed to be manufactured and shipped in several pieces and can be reassembled by a consumer with simple tools. The adjustable bed includes a number of support panels arranged end-to-end and interconnected by hinges so that individual panels can be articulated independent from other panels. The adjustable bed also includes a base having a bed frame that includes a pair of parallel opposed side rails, a rear rail, and a front rail. An adjustment mechanism is coupled to the base and adapted to manipulate a support panel. The adjustment mechanism includes a torque tube that is rotatably coupled to the frame and that engages a support panel so that when the torque tube is rotated by a motor coupled thereto, the support panel articulates, thereby adjusting the position of the bed.
- Further embodiments of the present invention provide for an adjustable bed with a simple and aesthetically pleasing appearance. In some embodiments, the adjustable bed includes a frame having a pair of parallel opposed side rails, a rear rail, and a front rail. The adjustable bed also includes a mattress support that has a center support panel secured to the side rails. A head support panel is pivotably connected to one side of the center support panel and a leg panel is pivotably connected to the other side of the center support panel. A foot panel is pivotably connected to the other side of the leg panel. The adjustable bed further includes an adjustment mechanism including two torque tubes adapted to articulate the head and leg panels. The torque tubes are removably coupled with the side rails via a bushing on both ends of each torque tube that is configured to fit and slide within a slot that runs along an inside wall of the side rail. The adjustable bed also includes a pair of foot links that provide stability and support to the foot support panel during articulation of the adjacent leg support panel.
- According to a further embodiment of the invention, an adjustable bed is provided that includes a mattress support having a head support panel, a stationary center support panel, a leg support panel, and a foot support panel. The head support panel is configured to be articulated using a head panel adjustment mechanism that includes a torque tube slidably coupled to the side rails. The foot support panel is elevated in response to articulation of the leg support panel, which is accomplished using a foot panel adjustment mechanism that includes a second torque tube slidably coupled to the side rails. An electric motor is provided for actuating the torque tubes as well as holding the torque tubes in place. Foot links provide support to the foot panel during articulation of the leg support panel.

Turning toFIG. 5 , after inserting thebushing 80 into theopening 92, thetorque shaft 42 slides up thelower portion 96 of theslot 94 and then onto an upper, roughlyhorizontal portion 98 of theslot 94. Thetorque shaft 42 can be slid along theupper portion 98 of theslot 94 until thetorque shaft 42 is oriented in an assembled position 100, as illustrated inFIG. 4 . - The present invention has been described in relation to particular embodiments, which are intended in all respects to be illustrative rather than restrictive. In embodiments, an adjustable bed is described that is configured such that the frame, adjustment mechanisms, motor and mattress support can be manufactured and shipped disassembled. In some embodiments, the adjustable bed can be assembled by a consumer with relative ease and simple tools. Moreover, as illustrated, for example, in
FIG. 6 , anadjustable bed 10 is presented that includessimple adjustment mechanisms 110 and other construction such that the adjustable bed has a simple and sleek appearance. In some embodiments, the adjustable bed doesn't include a complex assembly of mechanisms, thus limiting the necessity of attaching a shroud to the adjustable bed to mask such an assembly. Alternative embodiments will become apparent to those of ordinary skill in the art to which the present invention pertains without departing from its scope. - From the foregoing, it will be seen that this invention is one well adapted to attain all the ends and objects set forth above, together with other advantages which are obvious and inherent to the system and method. It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
