Description

Multi-purpose, multi-purpose and reconfigurable lounge chair bed

Reference to related applications

The application is a divisional application with application number 2016800557949 filed on 23/03/2018 by the applicant.

Technical Field

The present invention relates to a multi-purpose, multi-purpose and reconfigurable reclining chair bed. More particularly, the present invention relates to a reclining chair that can be converted into a bed.

Background

Lounge chairs that can be converted into beds are well known in the art. Lounge chairs typically include a seat, a backrest, and a leg rest. The recliner chair may be adjusted to an upright position and one or more reclined positions. The lounge chair can be used for common household use. Existing lounges cannot be converted to a flat lying bed when in the fully reclined position. In addition, because the backrest is supported solely by the links, the recliner may tilt rearwardly when in the fully reclined position.

The elderly, paralyzed patients, severe patients and disabled people require special equipment to perform daily activities. Bed-ridden people need to move around to perform daily activities, maintain hygiene and mental health. If the nursing staff assists the bedridden person to displace, move and lift, it is dangerous, cumbersome and painful for both the bedridden person and the nursing staff. In addition, maintaining sanitary conditions near the bed is cumbersome. The existing deck chair can not solve the problem of bedridden people.

Generally, various types of wheelchairs having an opening for defecation are known. The wheelchair has a seat plate provided with an opening. A receptacle is mounted below the opening for collecting feces and urine. This design provides a degree of convenience. However, since these types of wheelchairs are not generally equipped with an adjustable backrest, the bed-ridden person cannot sit for a long time. Furthermore, the wheelchair cannot be transferred to the fully reclined position and therefore the bed-ridden person must be transferred from the wheelchair to the bed.

To overcome the above drawbacks, us patent 8,359,685 proposes a wheelchair with a toilet bowl that can be converted into a bed. The wheelchair includes an outer rectangular main frame disposed on at least four wheel legs and connected to first, second, third and fourth frames by pivots or hinges. The movement of the first, second, third and fourth frames allows the wheelchair to be converted into a bed and vice versa. The toilet box or the toilet bowl is assembled below the outer rectangular main frame. In addition, a gasket is provided between the outer rectangular main frame and the toilet tank or the toilet bowl. The second frame and the third frame support the back and the legs, respectively, of the person. The main disadvantage of this wheelchair is that the second and third frames are connected to each other, preventing independent movement of the second and third frames. Further, a person with an injured leg or knee may be forced to bend the leg when used as a wheelchair. Thus, the wheelchair cannot reach the desired comfortable position. In addition, maintaining sanitary conditions and replacing the toilet tank or toilet bowl is cumbersome for the caregiver and the wheelchair cannot be moved over the toilet bowl. In addition, the wheelchair is not foldable, and occupies a large space. In addition, wheelchairs also do not provide lifting or tilting support for the patient.

To maintain sanitary conditions, bed-ridden people must be brought near the toilet. The bedridden person is moved towards the commode by the wheelchair and must be transferred to the commode. For some bed-ridden people, such removal or transfer may be difficult or impossible to accomplish. Therefore, there is a need for a wheelchair that is easily moved onto the toilet bowl to maintain sanitary conditions and avoid patient transfer. Further, there is a need for a lounge chair that is adjustable to any desired position.

In view of the above discussion, there is a need for a wheelchair that can be moved to any object or fixed facility, converted to a bed, adjusted to any desired position and that addresses the above-mentioned disadvantages of prior art reclining chair beds.

Disclosure of Invention

It is an object of the present invention to provide a multi-purpose, multi-purpose and reconfigurable reclining chair bed. The lounge chair bed comprises a first frame, a second frame, a backrest and a leg rest. The first frame has a front end and a rear end. The first frame allows the second frame to move telescopically into and out of the first frame. The first frame and the second frame form a hollow space that allows the recliner bed to move over a fixture or other object. The leg rest is attached to the front end of the first frame. A backrest is attached to the rear end of the first frame. When the lounge bed is in the seating position, the backrest and leg rest are in an upright (or near upright) position relative to the floor, and the second frame is located inside the first frame. When the lounge bed is in the sleeping position, the backrest and leg rest are in a horizontal (or near horizontal) position relative to the ground, and the second frame is pulled out from the first frame to support the backrest. The independent movement of the backrest and leg rest facilitates easy adjustment of the lounge chair bed to a desired comfortable position. The various mechanisms in the recliner bed may be operated mechanically or electrically or by using a combination of means. Furthermore, the recliner chair may be driven manually or electrically or by a combination thereof.

It is another object of the present invention to provide the required support for a person by providing a reclining chair bed with a tiltable seat. The seat is raised or tilted with the aid of a linear actuator to allow a person to easily leave the recliner bed in the sitting position.

The lounge bed can be folded and thus placed in a small space. Lounge beds have good stability and can be used for multiple purposes and for multiple utilities as a single device. The reclining chair bed provides safety, convenience and comfort for the elderly and the disabled. The couch bed provides sanitary conditions and is easy to clean and operate.

The recliner bed 100 is a multi-purpose, and reconfigurable chair and is used for daily activities. The couch bed 100 is a couch convertible to a bed. Fig. 1A and 1B show the lounge bed 100 in the sitting position and the sleeping position, respectively. The reclining bed 100 includes a first frame 102, a second frame 104, a backrest 106, and a leg rest 108. The sitting position is also referred to as an upright position.

Fig. 1A and 1B show a first frame 102 having a front end and a rear end. The first frame includes a first set of supports 110a-110b and a seat 112. The first set of supports 110a-110b includes a first support 110a and a second support 110b spaced apart from each other. In one embodiment, each of the first and

second supports

110a and 110b is a rectangular subframe. In yet another embodiment, the set of supports 110a-110b may be four support legs (not shown) spaced apart from each other. A seat 112 having a first end and a second end is supported on the first set of supports 110a-110 b. The seat 112 allows a person to sit on the lounge bed 100. Padding may be provided on the seat 112 to add additional comfort.

In one embodiment, the first and second ends of the seat 112 are pivoted to the respective front and rear ends of the first and

second supports

110a and 110b, respectively. In another embodiment, the second end of the seat 112 is attached to a set of linear actuators, such as lead screws (not shown) positioned on the rear ends of the first and

second supports

110a, 110b, and the first end of the seat 112 is pivoted to the front ends of the first and

second supports

110a, 110 b. The linear movement of the set of linear actuators is achieved by a first handle (not shown) rotationally fixed to the first frame 102. When the first handle is rotated, the lead screw moves linearly in a vertical direction with respect to the ground and raises or lowers the second end of the seat 112. The vertical movement of the seat 112 assists the person in sitting in the lounge chair bed 100 at a comfortable height and in a comfortable position. The set of linear actuators forms a lift mechanism for the seat 112. The lift mechanism allows the seat 112 to be tiltable. In addition, the vertical movement of the seat 112 provides additional support for a person to easily exit the recliner bed 100. The vertical movement of the seat 112 can also be achieved by means of hydraulic shafts and also by means of motors, such as servo motors and stepper motors. In yet another embodiment, the first end of the seat 112 may be attached to the set of linear actuators.

Fig. 1A and 1B illustrate a second frame 104 having a front end and a rear end that includes a second set of supports 114a-114B spaced apart from one another. The first frame 102 and the second frame 104 are telescopically engageable and retractable with each other. The second frame 104 fits comfortably inside the first frame 102. Further, the second frame 104 may be pulled out of the first frame 102 to any desired distance from the first frame 102. It will be apparent to those skilled in the art that the first frame 102 may also be moved into the second frame 104.

The recliner bed 100 includes a guide mechanism (not shown) that assists the second frame 104 in telescopically adjusting into and out of the first frame 102. In one embodiment, the first and

second supports

110a, 110b of the first frame 102 have rails that facilitate linear movement of the first and

second supports

114a, 114b of the second frame 104 into and out of the first and

second supports

110a, 110b, respectively. Such guide mechanisms having guide rails are well known in the art and further description thereof is omitted for the sake of brevity. In another embodiment, the first support 110a and the second support 110b of the first frame 102 each include one or more channels. The front ends of the second frame 104, i.e., the front ends of the first and

second supports

114a, 114b, are attached to one or more wheels that facilitate linear movement on one or more channels. The wheels may reduce friction and allow the second frame 104 to be easily moved into and out of the first frame 102. In yet another embodiment, the first frame 102 and the second frame 104 have telescoping tubes (not shown) that facilitate telescoping movement between the first frame 102 and the second frame 104.

In one embodiment, the second frame 104 is mechanically driven by a set of linear actuators, such as lead screws (not shown). The lead screw converts the rotational motion into linear motion. The set of linear actuators is positioned on the first frame 102 and attached to the second frame 104. The set of linear actuators is arranged and positioned such that rotation of a second handle (not shown) causes rotation of the set of lead screws. The rotation of the set of linear actuators in turn effects a linear movement of the second frame 104 into the first frame 102. The second handle is fixed to the first frame 102. In another embodiment, the second frame 104 is electrically driven by means of an actuating device, such as an electric motor. In yet another embodiment, the second frame 104 is driven by means of an acme screw (acme screw) and a drive mechanism such as a spur, worm, bevel, or helical gear. In yet another embodiment, the second frame 104 is driven by means of a chain or belt. To effect movement of the second frame 104 relative to the first frame 102, any suitable mechanism may be used without departing from the scope and spirit of the present invention.

The first frame 102 and the second frame 104 define a hollow space therebetween. The hollow space is formed by the first and

second supports

110a and 110b of the first frame 102 and the seat 112. When the first frame 102 and the second frame 104 slide past each other, the hollow space formed is unobstructed by the frames/linkages. The hollow space allows the recliner bed 100 to be moved over any desired object or stationary facility, such as a toilet bowl, cabin trunk, etc. In addition, the hollow space allows the recliner bed 100 to be used in confined spaces such as RVs, airplanes, and cubicles.

The backrest 106 has a first end and a second end. A first end of the backrest 106 is attached to a rear end of the first frame 102.

second scissor lifts

116a, 116b are attached to the backrest 106. The second ends of the first and

second scissor lifts

116a, 116b are attached to the first and

second frames

102, 104. Movement of the second frame 104 relative to the first frame 102 automatically adjusts the first scissor lift 116a and the second scissor lift 116 b. The automatic adjustment of the first scissor lift 116a and the second scissor lift 116b by the movement of the second frame 104 helps the backrest 106 achieve any desired position. The second frame 104, together with the scissor lift mechanism, provides the desired stability to the backrest 106. In one embodiment, a first set of links (not shown) are attached to the backrest 106 and the second frame 104 to hold the backrest 106 in an upright position or any comfortable position. The first set of links is attached to a set of linear actuators (e.g., lead screws), which are in turn attached to the rear end of the second frame 104. Rotation of the lead screw allows the backrest 106 to achieve any desired position. To adjust the first set of links on the second frame 104, any suitable mechanism may be used without departing from the scope and spirit of the present invention. The backrest 106 may be adjusted to any position by any other suitable mechanism without departing from the scope of the present invention. Further, the second frame 104 may be pulled out to a desired distance from the first frame 102 to provide additional support to the backrest 106 in all positions.

A leg rest 108 having a first end and a second end is attached to the front end of the first frame 102. A second set of

links
