Description

Adjustable bed system with swivel bed frame [Cross-reference to related applications]

This application is a partial continuation of U.S. Patent Application No. 15/659,412 filed on July 25, 2017, and claims priority to U.S. Patent Application No. 62/366,920 filed on July 26, 2016. All disclosures in these applications are hereby incorporated by reference.

Specific embodiments of the subject matter disclosed herein relate to an articulating bedding system (note: articulating means a joint with movable joints, referred to as "articulating" herein).

Adjustable or articulating beds have the ability to selectively adjust the bottom or foot and top or head of the mattress from a traditional flat or horizontal position. Therefore, the user's head or feet may be elevated as desired for comfort, snoring relief, or reading convenience. The upper and lower portions are adjustable independently of each other. Adjustment is achieved via a hinged base that is mounted on the frame and supports the mattress.

Support members, hydraulic and pneumatic lifts and actuators associated with an adjustable bed are positioned below the sleeping surface of the adjustable bed and extend downwardly toward the floor. The adjustable bed system is placed on a frame with a plurality of side rails, which conceal the aforementioned support members, as well as lifts and actuators. The side rails typically extend to the floor and define a certain distance from the floor, or height of the sleeping surface. This height is at least the minimum height required to accommodate all support members, hydraulic and pneumatic lifts, actuators, and other electronics that provide the desired articulation in the adjustable bed.

Although living room furniture and bathroom equipment such as showers and bidets have been designed with people with mobility issues in mind, adjustable beds, although they provide improved comfort and customization in bed, do not take care of people who have difficulty getting in and out of bed. The mattress does not rotate or tilt to assist in properly positioning the body on an adjustable bed. In addition to this, the positioning of support members, lifts and actuators below the adjustable bed where they are integrated with the bed frame can result in further inhibiting the ability of a person with reduced mobility to get in and out of the bed when the adjustable bed has a sleeping surface that is located higher than the floor. . Therefore, it would be desirable to have an adjustable bed system that overcomes these limitations of conventional adjustable beds.

In another embodiment, a plurality of bearings, including ball bearings and roller bearings, are disposed between the support plate and the support plate, such as in channels or grooves in the support surface, to improve the connection between the support plate and the support plate. This supports rotation between plates.

In a specific embodiment, the support plate is fixedly attached to the spindle 166 and does not rotate about the spindle. Therefore, the rotation of the rotating shaft will cause the support plate to rotate. Please refer to Figure 13. In a specific embodiment, the rotation actuator 252, that is, the actuator that provides rotation of the support plate, is a linear actuator, and the linear actuator is disposed in the fixed frame 222. And it is connected to the frame member 224 in the fixed frame in a rotary or pivoting manner. The extendable rod 254 of the rotary actuator is connected to an arm 258 that is attached to and extends from the axis of rotation 260 at a fulcrum 256 . The rotating shaft is fixedly connected to the support plate. Therefore, when the rotary actuator is in a first position, such as retracted, the support plate is in a first non-rotational position 218 . Extending the extendable rod moves the rotary actuator to the second position 262 and the arm to the second position 226. This also rotates the spindle and moves the support plate to a second rotated position 220, which represents a 90° rotation in the first direction. Rotating the shaft, and thus the support plate 90°, in a second direction opposite to the first direction can be achieved by positioning the arm in the reverse first position 264 .

Returning to Figures 1 to 10, in another specific embodiment, the motor is configured to be connected to the end of the rotating shaft, and the rotating shaft is disposed in the rotating and pivoting frame. The motor is fixedly attached to the spindle and to the rotating and pivoting frame, such as the support plate. The motor therefore causes the support plate, and therefore the swivel and pivot frame, to rotate about the axis of rotation. In another specific embodiment, the motor 164 is disposed in the fixed frame and contacts a portion of the rotating shaft disposed in the fixed frame. The motor is fixedly attached to the fixed frame and to the rotating shaft. In addition, the rotating shaft extending into the rotating and pivoting frame is fixedly fastened to the rotating and pivoting frame, that is, the supporting plate. Therefore, the motor rotates the rotating shaft about the vertical axis, and the rotating shaft rotates the rotating and pivoting frame about the vertical axis.

In one embodiment, the rotating and pivoting frame includes a pair of parallel frame members 182 spaced apart from each other and extending below the articulating center portion and the articulating center portion frame. Each frame member includes a top 184, and the articulated central frame is articulated to each top from an initial position contacting or adjacent to the top and parallel to the tops to the articulated central frame and each top. Clamp an angle position. In a specific embodiment, each frame member is connected to the articulated central frame, such as at a fulcrum, such as a pivot joint. In a specific embodiment, the articulating center portion is attached to each frame member to provide both pivoting and sliding movement of the articulating center portion to the rotating and pivoting frame.

In a specific embodiment, each parallel frame member is fastened to the support plate, such as by welding or using a plurality of fasteners such as bolts. In one embodiment, each frame member is attached to the support plate using three fasteners, one fastener adjacent either end of the frame member and one fastener located on the frame member. middle. Therefore, the rotation of the support plate will cause the parallel frame members to rotate. The fasteners do not interfere with the rotation of the support plate to the support plate. In a specific embodiment, the pivot actuator 168 is disposed on the support plate between the parallel frame members. Preferably, the pivot actuator is a linear actuator. The pivot actuator is disposed between the support plate and the articulated center frame, and is pivotally attached to the support plate and the articulated center frame. Movement of the pivot actuator, and in particular of the push rod of the pivot actuator, will produce a pivot movement of the articulating central part. Therefore, the rotation and pivot frame contains four actuators, namely a head actuator, a foot actuator, a rotation actuator and a pivot actuator. In a specific embodiment, all four actuators are linear actuators. In one embodiment, all four actuators are identical actuators.

Referring now to FIGS. 14 and 15 , in one embodiment, the pivot actuator 308 is pivotally connected to the support plate 306 between the parallel frame members 304 . The end of the extendable rod 310 of the pivot actuator is rotatably or pivotally connected to the articulating center frame 302 . In one embodiment, the extendable rod is connected to the distal end 314 of the articulating center portion adjacent to the articulating foot and is spaced a distance 312 apart. In one embodiment, the distance is approximately 8 inches. When the pivot actuator is in the first retracted position, the articulated central frame 302 is generally flat and is located above and parallel to the top surfaces 318 of the parallel frame members. (Picture 14). Extending the extendable rod will cause the articulating center frame, and therefore the articulating bed member, to pivot towards the foot end (Fig. 15). This will lift the articulating center frame away from the top surfaces of the parallel frame members and define an angle 316, the pivot angle, between the articulating center frame and the top surfaces.

Referring now to Figures 18 to 22, the rotating and pivoting frame includes a rotating drive shaft 466 extending through a supporting plate 418 and centered on a vertical axis 448. In a specific embodiment, the rotational driving shaft is a cylindrical shaft concentric with the vertical axis. The rotary drive shaft includes a mounting flange 470 disposed on a first end 472 of the rotary drive shaft. The rotary drive shaft also includes a second end 474 opposite to the first end. The support plate is disposed between the first end and the second end of the rotational drive shaft, that is, the rotational drive shaft passes through the support plate. In addition, the rotary drive shaft including the mounting flange is located below the bearing plate 469 . In a specific embodiment, the mounting flange is in contact with the support plate, particularly the bottom surface 476 of the support plate. In a specific embodiment, the mounting flange is fastened to the bottom surface of the support plate using a plurality of fasteners 478 that pass through the support plate. Therefore, the fasteners among the plurality of fasteners can be accessed from the top surface 480 of the support plate. As shown, four fasteners are used to fasten the mounting flange to the support plate. Suitable fasteners include, but are not limited to, threaded fasteners such as screws and bolts.

In one embodiment, the rotary drive shaft is hollow and includes a passage 482 that extends completely through the rotary drive shaft from the first end and mounting flange to the second end. The passage is aligned with the hole 484 in the support plate at the first end of the rotary drive shaft. The access and alignment holes in the support plate provide a conduit for routing wiring, including power cables and control wiring, for the actuators and other components of the swivel and articulated bed from below or from the fixture. The inside follows the route into the rotating and pivoting frame to the articulated bed component. By passing the wiring through the passage in the rotary drive shaft, the wiring will not rotate or twist. In addition, the wiring should not contact or interfere with the movement of the rotating components.

The swivel and pivot frame includes a plurality of discrete bearings 486 disposed between the support plate and the horizontal support surface. The swivel and pivot frame can rotate about a vertical axis 448 against horizontal support surfaces on a plurality of discrete bearings. Each discrete bearing is separate, spaced and independent from other discrete bearings. Thus, each discrete bearing is positioned on, attached to, and removed from the support plate independently of all other discrete bearings. In one embodiment, each discrete bearing includes a housing 488 mounted to the support plate. In a specific embodiment, the housing is arranged as a flange mounted to the underside of the support plate.

The number and arrangement of discrete bearings between the support plate and the horizontal support surface may vary. Suitable numbers of discrete bearings include at least three discrete bearings, at least four discrete bearings, at least five discrete bearings and more than five discrete bearings. In one embodiment, the swivel and pivot frame includes five discrete bearings. Each discrete bearing is spaced a given distance from the vertical axis, and therefore the rotary drive shaft. In a specific embodiment, the given distance is sufficient to support the force and load exerted on the support plate by the rotating and pivoting frame cantilevered by the vertical rotating shaft and the rotating driving shaft and the articulated frame member. Therefore, placing a discrete bearing at the given distance between the support plate and the support surface will prevent tilting between the support plate and the support surface.

In a specific embodiment, each of the plurality of discrete bearings is spaced an equal distance from the vertical axis along the support plate. Alternatively, the discrete bearings of the plurality of discrete bearings are spaced from the vertical axis at two or more different distances.

The bearings in the discrete bearings may also be configured in other configurations, such as along radial lines extending from the vertical axis, including straight lines and curves.

Since the mounting flange of the rotary drive shaft is attached to the support plate, the load placed on the support plate will be converted into an axial load along the rotary drive shaft. Although the swivel and pivot frame may only include the plurality of discrete bearings between the support plate and the support plate, in a specific embodiment, the swivel and pivot frame includes one or more thrust bearings. The bearings are adapted to accommodate the axial loads along the rotary drive shaft and at the same time provide rotation of the rotary drive shaft. In a specific embodiment, the rotating and pivoting frame includes an upper bearing assembly 500 . The upper bearing assembly includes an upper bearing housing 502 disposed between the mounting flange and the support plate. There is an upper bearing assembly thrust ball bearing 504 disposed within the housing. The rotary drive shaft passes through the upper bearing assembly and the thrust ball bearing.

The thrust ball bearing includes an upper bearing ring 506 in contact with the mounting flange and a lower bearing ring 508 in contact with the housing. The thrust ball bearing is therefore spaced from the support plate by the housing. In a specific embodiment, the lower bearing ring is in contact with the support plate. A plurality of ball bearings 510 are disposed between the upper bearing ring and the lower bearing ring. The rotary drive shaft is in contact with the plurality of ball bearings, and the rotary drive shaft and the mounting flange rotate against the upper bearing assembly.

In a specific embodiment, the upper threaded locking ring is in living contact with the lower bearing of the lower bearing assembly to provide rotation of the rotational drive shaft in the thrust ball bearing. The upper threaded locking ring fastens the rotating and pivoting frame to the support plate and holds the lower bearing assembly against the bottom surface of the support plate. Removing the upper threaded locking ring will provide access to the bearing assemblies for removing the swivel and pivot frame from the fixed frame.

In a specific embodiment, a wrench tool such as a spanner wrench is used to remove the upper threaded locking ring. The upper threaded locking ring includes a pair of external notches 524 for the tang of the open end wrench to engage to facilitate rotation and removal of the upper threaded locking ring. In a specific embodiment, the open-end wrench is specially arranged for the configuration of the notches to facilitate the removal of the threaded locking ring and at the same time prevent the threaded locking ring from being removed with conventional wrenches or tools.

In one embodiment, the rotation and pivot frame includes a removable drive collar 526 disposed above the rotation drive shaft and adjacent the second end. The drive collar is removable and slidable from the second end onto the rotating drive shaft. Although the drive collar is axially movable along the rotary drive shaft, the drive collar and the rotary drive shaft are arranged to engage with each other such that the drive collar cannot rotate relative to the rotary drive shaft. Therefore, rotation of the drive collar will cause the rotation of the rotary drive shaft. In a specific embodiment, a pin can be inserted through the driving collar and the rotating driving shaft. Alternatively, the rotary drive shaft includes a shape, groove, or ridge along a portion of its length adjacent the second end that corresponds to a corresponding shape, ridge, or groove on the interior surface of the drive collar. Engagement. This meshing converts the rotational motion of the drive collar to the rotating drive shaft.

The swivel and pivot frame also includes a second lower threaded locking ring 540 that is threaded onto the rotational drive shaft at the second end of the rotational drive shaft. The lower threaded locking ring is threaded to the second threaded portion 544 of the rotational drive shaft, which extends from the second end along a portion of the length of the rotational drive shaft. The lower threaded locking ring is in live contact with the drive shaft. The lower threaded locking ring holds and fastens the drive collar on the rotating drive shaft. Removing the lower threaded locking ring will provide for removal of the drive collar. In one embodiment, a wrench, such as an open-end wrench, is used to remove the lower threaded locking ring. The lower threaded locking ring includes a pair of external notches 544 for the tang of the open end wrench to engage in order to rotate and remove the lower threaded locking ring. In a specific embodiment, the open-end wrench is specially arranged for the configuration of the notches to facilitate the removal of the threaded locking ring while preventing removal of the threaded locking ring with conventional wrenches or tools.

In one embodiment, the drive collar includes a pair of arm assemblies 528 extending from the drive collar. In another embodiment, the drive collar includes a pair of opposing arms. Each arm assembly extends radially from the drive collar and vertical shaft. In a specific embodiment, the arm assemblies are diametrically opposed. Alternatively, the arm assemblies extend from the drive collar along separation radii defining an included angle from about 90° to about 180°. In one embodiment, each arm assembly includes a pair of spacer arms 530 , ie, separate arms that are axially spaced apart from each other along the length of the rotary drive shaft and drive collar. The spacer arms create or define a bracket. The rotating and pivoting frame includes a rotating actuator 532 that is in contact with the fixed frame and one of the arm assemblies. Therefore as shown in the figure, the swivel and pivot bed contains four actuators, namely a head actuator, a foot actuator, a rotation actuator and a pivot actuator. In a specific embodiment, all four actuators are linear actuators. In one embodiment, all four actuators are identical actuators.

In a specific embodiment, a push rod or extendable end 534 of a rotary actuator is provided between the spaced arms of one of the arm assemblies, and the rotary actuator is a linear actuator. A fixing pin 536 is inserted through the hole in each spacer arm, and when the rotary actuator is attached to a specific fixed arm assembly, the fixing pin 536 passes through the end of the extendable rod to secure the extendable rod. The rod is in a bracket formed by the equally spaced arms. The extendable arm is rotatable against the fixed pin.

Referring now to Figures 23 and 24, the fixed drive end 548 of the rotary actuator 532 is pivotally attached to one of two actuator mounting brackets 544. Attached to vertical frame members 546 which extend downwardly from the inner cross-frame members 542 of the fixed frame 402 . In one embodiment, the actuator mounting bracket is a "U" shaped bracket, and the fixed drive or motor end of the rotary actuator is retained in the bracket with a retaining pin. Therefore, the rotary actuator can rotate or pivot within the holder mounting bracket to which it is attached. The use of retaining pins to secure the rotary actuator in the mount mounting brackets between the spaced arms of the drive collar will provide for easy attachment of the rotary actuator to the mount and Drive collar. This attachment can be performed after the bed has been assembled and erected, and can be easily changed. The selection of the fixed frame mounting bracket and spacer arm on which the rotation actuator is mounted will determine the direction of rotation of the rotation and pivoting frame.

As illustrated in Figure 23, attaching the rotary actuator to the stationary mounting bracket and spacer arm generally to the left of the vertical axis and rotary drive shaft will produce rotation as indicated by arrow G. Attaching the rotary actuator to another fixed frame mounting bracket and spacer arm generally to the right of the vertical axis and the rotary drive shaft will produce rotation as indicated by arrow H. Therefore, the swivel and pivot frame can rotate about the vertical axis by an angle of approximately 90° in a first rotational direction (arrow G) and by an angle of approximately 90° in a second rotational direction (arrow H).
