FIELD OF THE INVENTION
This invention relates generally to a bedding foundation having a lift actuator and linear actuator to move a roller or similar apparatus to impart a massage effect on a mattress above the foundation.
BACKGROUND OF THE INVENTION
In the bedding industry, bases or foundations for supporting mattresses fall into two categories: 1) stationary foundations, which do not have any moving parts, and 2) adjustable bed bases which are usually motorized and have moving parts for inclining a portion of a mattress resting on the adjustable bed base and sometimes vibrating a portion of a mattress resting on the adjustable bed base.
Commonly adjustable bed bases include one or more motors which activate one or more drivers of the adjustable bed base to raise a portion of the bed base and mattress. In addition, such adjustable bed bases may include one or more vibratory motors which may impart vibrations to the mattress for a “massage” type effect or feel. Consequently, due to the hardware and electronics necessary to move a portion of an adjustable bed base, the adjustable bed base may be heavy and difficult to transport. Conventional stationary bedding foundations are commonly much lighter and easier to transport.
Adjustable bed bases are typically more expensive than conventional stationary bedding foundations because they have one or more motors for moving parts. Thus, a need exists in the bedding industry for a bedding foundation which combines desirable features of both adjustable bed bases and conventional standard bedding foundations.
SUMMARY OF THE INVENTION
According to one aspect of the invention, a bedding foundation comprises a generally rectangular frame supported by legs and a rigid platform supported by the generally rectangular frame. The rigid platform has an opening covered by a cover. The cover is conventionally secured to the rigid platform.
Two roller rails are secured to a lower surface of the rigid platform. The roller rails extend from head to foot and are generally parallel. Each of them is a unitary member having an inverted V-shaped lower portion.
The bedding foundation further comprises two uprights secured to each of the roller rails, two per side. The uprights are stationary, the same size and generally vertically oriented. Stationary cross members are secured to the uprights. Each cross member extends between two uprights and is generally horizontally oriented. A linear actuator extends between the cross members and may be remotely actuated. The linear actuator moves a bus from front to back of the bedding foundation. A roller tray bracket is secured to the bus and moves linearly with the bus.
A roller carriage is secured to the roller tray bracket and is movable by the linear actuator from front to back of the bedding foundation. The roller carriage includes a roller tray and a lifter inside the roller tray for lifting a lifter plate. The roller carriage further comprises two roller mounting brackets secured to the lifter plate. The roller extends between the roller mounting brackets. The roller carriage further comprises a chassis having two side members and two connecting members extending between the side members. Two stubs extend downwardly from each of the side members of the chassis and are secured to the roller tray. The roller carriage further comprises four wheels, two per side. Each of the wheels is mounted on a wheel pin which extends through one of the side members of the chassis. Each of the wheels has a groove therein which receives the inverted V-shaped portion of one of the stationary roller rails. When the linear actuator moves the roller carriage horizontally the wheels and stationary roller rails guide the movement of the roller carriage. The roller moves horizontally with the roller carriage but may be moved in a vertical direction by the lifter which moves with the roller carriage as well.
In a second aspect, a bedding foundation comprises a frame supported by legs and a rigid platform supported by the frame. The rigid platform has an opening covered by a flexible cover. The flexible cover is conventionally secured to the rigid platform. In some instances, the flexible cover may be omitted.
The bedding foundation further comprises a lift mechanism suspended by the rigid platform. The lift mechanism comprises roller rails secured to a lower surface of the rigid platform. The roller rails extend from head to foot and are generally parallel. Each of them is a unitary member having an inverted V-shaped lower portion.
The lift mechanism further comprises two uprights and two cross members. The uprights are the same size and generally vertically oriented. The cross members are secured to the uprights. Each cross member extends between two uprights and is generally horizontally oriented. The lift mechanism further comprises a linear actuator below the rigid platform. The linear actuator extends between the cross members and may be remotely actuated. The linear actuator moves a bus from front to back of the bedding foundation. A roller tray bracket is secured to the bus and moves linearly with the bus.
A roller carriage is operatively coupled to the linear actuator and moveable by the linear actuator from front to back of the bedding foundation. The roller carriage includes a roller tray, a chassis and a lifter secured inside the roller tray for lifting a lifter plate. The roller carriage further comprises two roller mounting brackets secured to the lifter plate. The roller extends between the roller mounting brackets. The chassis has two side members and two connecting members extending between the side members. Two chassis further comprises stubs connecting the side members of the chassis to the roller tray. The stubs extend downwardly from each of the side members of the chassis and are secured to the roller tray. The roller carriage further comprises four wheels, two per side. Each of the wheels is mounted on a wheel pin which extends through one of the side members of the chassis. Each of the wheels has a groove therein which receives the inverted V-shaped portion of one of the stationary roller rails. When the linear actuator moves the roller carriage horizontally the wheels and stationary roller rails guide the movement of the roller carriage. The roller of the roller carriage is sized to fit through the opening in the rigid platform and is movable in a horizontal direction by the linear actuator and movable in a vertical direction by the lifter which moves with the roller carriage as well.
In a third aspect, a method of providing a massaging feeling to a mattress from a massage mechanism built into a bedding foundation. The first step in the method comprises raising a roller through an opening in a rigid platform using a lifter. The roller remains below a flexible cover covering the opening in the rigid platform. The rigid platform is supported by a generally rectangular frame supported by legs.
The next step in the method is moving the roller from front to back inside the opening with the roller in its raised position by activating a linear actuator. The linear actuator extends between cross members, the cross members extending between uprights mounted to roller rails. The roller rails are mounted to the rigid platform. The linear actuator horizontally moves a bus. A roller tray bracket is secured to the bus. A roller tray of a roller carriage is secured to the roller tray bracket. The roller carriage further comprises wheels engaging the roller rails for guiding movement of the roller carriage. The lifter is inside the roller tray and lifts a lifter plate and two roller mounting brackets secured to the lifter plate when activated. The roller extends between the roller mounting brackets.

Bedding foundation 10c comprises a generally rectangular frame 12c comprising two end rails 14c and two side rails 16c, only one being shown. Although not shown, legs may support the rectangular frame 12c above the ground a desired distance. The generally rectangular frame 12c is shown resting on a generally rectangular base 13 which is stationary regardless of the position of the generally rectangular frame 12c.
The generally rectangular frame 12c is movable between a lowered position shown in FIGS. 10A and 10B and an inclined position shown in FIG. 10C via operation of a lift mechanism 176. Although FIGS. 10A-10C illustrate the lift mechanism 176 proximate the foot end 24c of the bedding foundation 10c, another lift mechanism (not shown) may be located at the head end 22c of the bedding foundation 10c to incline the head end 22c of the bedding foundation 10c. As illustrated in FIG. 10C, the lift mechanism 176 inclines the foot end 24c of the bedding foundation 10c relative to the head end 22c of the bedding foundation 10c.
As best shown in FIG. 10A, each side rail 16b (only one being shown) has a linear slot 156 cut therein. A first pin 158 moves inside the linear slots 156 of the side rails 16c and extends therebetween. A lever 160 extends from the first pin 158 to a second pin 162. A roller 164 surrounds the second pin 162. The roller 164 may be rotatable or not. The roller 164 moves between a lowered position shown in FIG. 9A and a raised position shown in FIG. 9B in any known manner. FIGS. 10A-10C show the roller 164 in a lowered position. When the roller 164 is in its raised position, the roller 164 exerts an upward force on the lower surface 166c of mattress 11c causing a bump or raised portion (not shown) in the upper surface 170c of mattress 11c, like shown in the mattress 11b of FIG. 9B. As shown in FIG. 10A, when the roller 164 is in its lowered position, the roller 164 does not exert any upward force on the mattress 11c and upper surface 170c of the mattress 11c is generally planar.
FIG. 10A shows a front lift actuator 178 in front of the roller 164 and a rear lift actuator 180 located behind the roller 164. A front platform 179 is secured to the top of the front lift actuator 178 and a rear platform 181 is secured to the top of the rear lift actuator 180. The front lift actuator 178 moves the front platform 179 between a lowered position shown in FIG. 10A and a raised position shown in FIGS. 10B and 10C. The rear lift actuator 180 moves the rear platform 181 between a lowered position shown in FIG. 10A and a raised position shown in FIGS. 10B and 10C. The front lift actuator 178 is operated independently from the rear lift actuator 180 although each drawing shows them in the same position. For example, the front lift actuator 178 may be in a raised position while the rear lift actuator 180 is in a lowered position.
The front lift actuator 178 may be raised and lowered regardless of the position of the roller 164. Similarly, the rear lift actuator 180 may be raised and lowered regardless of the position of the roller 164.
As shown by the arrow 184 shown in FIG. 10A, when the front lift actuator 178 is activated and the front platform 179 raised, the upper surface 170c of mattress 11c is raised at the front of the mattress 11c. As shown by the arrow 186 shown in FIG. 10A, when the rear lift actuator 180 is activated and the rear platform 181 raised, the upper surface 170c of mattress 11c is raised at the rear of the mattress 11c.
FIG. 11 illustrates a flow chart showing the general operation of an adjustable bed in accordance with the present invention. FIG. 11 shows a user interface 190 such as an application on a mobile phone. An operator may manipulate the user interface to select an intensity of massage from zero to one hundred percent. The percentage of intensity chosen determines the height of the roller and thus the upward force exerted on the mattress above the adjustable bed. An operator may further manipulate the user interface to select a speed of travel of the roller from zero to one hundred percent. The percentage of speed chosen determines the speed of travel of the roller and thus the massage feeling exerted on the mattress above the adjustable bed. An operator may further turn a wave action on or off using the user interface 190.
A logic chip sends the control commands to an actuator control box 192 and calculates the timing between commands. A logic chip 192 receives a Wi-Fi command from the user interface and issues a command to a control box 194. The control box 194 controls the electrical signals that control the actuators via commands sent from the logic chip. Although FIG. 12 shows the control box at a specific location, it may be located at any desired location.
The various embodiments of the invention shown and described are merely for illustrative purposes only, as the drawings and the description are not intended to restrict or limit in any way the scope of the claims. Those skilled in the art will appreciate various changes, modifications, and improvements which can be made to the invention without departing from the spirit or scope thereof. The invention in its broader aspects is therefore not limited to the specific details and representative apparatus and methods shown and described. Departures may therefore be made from such details without departing from the spirit or scope of the general inventive concept. For example, the roller concept of the present invention may be used in an adjustable bed base. Any of the hollow members of the bedding foundation may be at least partially solid. The invention resides in each individual feature described herein, alone, and in all combinations of any and all of those features. Accordingly, the scope of the invention shall be limited only by the following claims and their equivalents.
