Description:
[0001]    Claiming priority from: Prov App No. 60/724,190, filed Oct. 6, 2005 and application Ser. No. 11/538,328 Currently Pending filed Oct. 3, 2006 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present disclosure relates to an Adjustable Multipurpose Adult Mobility Device, whereby Adult persons who are of limited ambulatory means either through handicap, weakness, balance or neurological issues, are able to be moved comfortably or able to move themselves in more comfort than the prior art discloses and practices. This device due to it&#39;s self-controlled movement prevention features also serves as a device to assist those who need a steady platform in which to lean against whilst standing or to aid in their own ambulatory process. 
       BACKGROUND OF THE INVENTION 
       [0003]    The current selection of flexible mobility devices for adolescents and adults having limited mobility, vitality, balance issues, or neurological difficulties, is limited. An overwhelming number of Americans, over 54 million as of the last Census report, suffer from some form of limited mobility. There are over 15 million who, alone, use walking canes. These numbers are sure to escalate as a growing percentage of the population reaches retirement age. By 2030, approximately twenty percent of the entire population will be 65 years old or older. Additionally, nearly one in a dozen adolescents has some form of physical or mental disability that precludes easy, pain free ambulatory transportation. Thus, there is already a large need to have access to easily transportable devices for aid in mobility of every aspect of life. While the selection of strollers for babies and infants may be abundant, the market for adult strollers has yet to develop. Targeting individuals in the above market is critical to adequate health care, especially considering the target consumer is increasing in percentage population. 
         [0004]    Individual consumers in the targeted adult stroller market might specifically include persons afflicted with restricted ambulatory movement and their corresponding caregivers. On a broader scale, corporations comprising the $1.1 trillion United States medical industry also fall into the targeted market. Hospitals, health care facilities, and nursing homes are all potential consumers as these institutions strive to provide maximum comfort and flexibility for patients of all ages and sizes. These institutions have an abundant access to wheel chairs and fully motorized scooters. But, wheel chairs and fully motorized scooters are often heavy, obstructive, and require special facilities and retrofitted vehicles to transport equipment. This adjustable adult mobility device is specially designed to eliminate the downfalls of these devices by being lightweight, versatile, and collapsible for easy storage and transportation. There is also a market for those adults that do have limited mobility and wish to have control over their daily lives without the need for additional help. Flexibility and versatility allows these passengers to go more places and thus have fuller life experiences while riding in comfort. 
         [0005]    Ambulatory injuries impair mobility and hence preclude enjoyment of many of life&#39;s activities. Such injuries might include spinal cord damage, stroke, advanced osteoporosis, and hip or joint replacement. While individuals may not be fully dependent on a wheelchair, getting from one place to another can be time-consuming, difficult, and frustrating without the aid of a mobility device. This is often the case in instances where an individual is required to walk or stand in one place for an extended period of time. Limited movement not only frustrates the person with the disability, but can often instill frustration with companions, caregivers, or other individuals having an intimate relation with the disabled person. Other types of chronic illnesses such as heart conditions, cancer, and other degenerative diseases may also make physical transportation difficult. Balance and coordination issues are also brought on by such conditions as head trauma, Parkinson&#39;s disease, Alzheimer&#39;s disease, Meniere&#39;s disease, dementia, or even middle ear disturbances. Individuals afflicted with such ambulatory restrictions will find relief in an adult stroller in their everyday lives as a mobility aid. 
         [0006]    Prior art is replete with examples of strollers which are used for children and in limited ways adults. In particular, there is prior art that has shown the use of shock absorbing technologies. Basically the current state of the art in absorbing or cushioning the shocks of the road are focused either on the drivetrain or wheel subsystems, such as U.S. Pat. No. 4,455,031 issued to Hosaka on Jun. 6, 1984 or Published Application 2007/0114754 published May 24, 2007 by Santos etal, which focuses on the absorbing the bumps in the road through the wheels suspension system, or the seat itself, such as in Published Application 2006/0016648 to Lin published on Jan. 26, 2006. Problems are that shock absorbers mounted in the vertical plane are responsive to the shock and rely on the strength of the spring to support the weight of the occupant. A spring stiff enough to provide support to an adult is going to be so stiff as to transmit a significant amount of vibration directly to the spine or back of the user. It is an object of this invention to provide a shock absorbing system whereby the bumps and potholes of the road are not transmitted directly to the rider and especially to the riders back, regardless of the riders weight. 
         [0007]    Another issue with the current state of the art is the absence of variable braking systems that incorporate a disc system of braking that provides instant selective braking rather than the pin and spoke arrangement of U.S. Pat. No. 5,370,408 issued to Eagan on Dec. 6, 1994 and most current infant or baby strollers with a foot operated flip brake, which provides either a complete retardation of movement by locking the wheels or complete free-wheeling. It is an object of this invention to provide a braking system which is at a rest position engaged by friction between a disc brake rotor and a set of brake shoes at an infinitely number of locations about said rotor, and is capable of selective reduction of said friction by application of pressure. 
         [0008]    Thus, there exists a significant need for an adult mobility device capable of transporting an adolescent or adult having limited mobility, balance issues, or neurological difficulties. Such an improved stroller should include a lightweight and/or foldable construction for easy movement, a means for protecting a passenger from the environment, capacity for transporting medical devices or other goods, and a mechanism to control the stroller when left unattended with a passenger inside. The present invention fulfills these needs and provides further related advantages. 
         [0009]    It is the principle object of this invention to provide an adult mobility device which combines the comfort of a cushioned ride which is adaptable to the needs and requirements of the adult rider. Another object of this invention is to provide a mobility device that has a braking system that is controllable by the occupant or the caregiver. It is another object of this invention to allow the rider of this device to be able to self-propel themselves or be provided mobility by the caregiver. 
       SUMMARY OF THE INVENTION 
       [0010]    Herein disclosed is a specially designed assistive mobility device configured for use by adolescents and adults. This adult mobility device includes four wheels and a frame manufactured from a light weight material such as heavy gauge nylon or vinyl, composites, aluminum, or other suitable material. This frame would ideally be tubular in design to facilitate a lighter weight, greater strength and provide a means to conceal control cables inside of the frame to prevent breakage, wear and snagging The durable, yet flexible design allows the adult mobility device to be used in parks, stores, amusement parks, and around town. The adult stroller provides adolescents and adults a means for a safer, easier, and comfortable mode of transportation. Adult stroller passengers will be able to once again go shopping, see movies, and enjoy parks, even in inclement weather. The stroller is easily storable, has a variety of safety features, is perfectly adjustable, and is an ideal replacement for wheel chairs and fully motorized scooters. 
         [0011]    The adult mobility device frame is versatile and foldable for easy storage. In general, the frame is supported by a series of four wheels. Two wheels in the front are fixed while the two rear wheels swivel. Although, a variety of wheel combinations are possible. Mobility device&#39;s movement is controlled by a person through use of a rear handle that curves back similar to a shopping cart. An embodiment will provide the person to control the movement of the mobility device through his own means, either through the application of force onto the front wheels by their hands or by an extended arm which can ratchet the front wheel in either direction using the concept found in socket wrenches. Also integrated into the frame design is a brake bar located on each side of the rear handle. The brake bar runs adjacent down the side of the frame and connects to a brake unit. When resting, the brake unit engages and locks at least one of the mobility device wheels. This safety feature prevents inadvertent movement or accidental rolling of an unattended stroller. A person, such as a caregiver, attempting to move the mobility device need only pull the brake bar to disengage the brake unit. An embodiment of this invention is having the person be able to move the device themselves and as such, the user is equipped with their own brake bar to release the brake pressure on the device. After stopping and releasing the brake bar, the brake unit reengages at least one of the wheels to again prevent movement. 
         [0012]    The adult mobility device also includes a front weather shield. A combination of the canopy and the front shield protects an adult mobility device passenger from the environment—including the sun and inclement weather. A section of the front shield is manufactured from a clear plastic material to allow a passenger to see out. The bottom portion of the front shield may be made from any weather resistant material, such as nylon. While the front shield may be designed in many different sizes, the front shield should ideally be long enough to completely cover a passenger&#39;s legs and feet. The front shield may substantially cover and connect to a front portion of the frame to further protect the passenger from the outside environment. For storage, the front shield may be folded under the canopy or folded above the canopy or the support structure and canopy can be removed completely. Additionally, a rear shield (not shown) can be stored underneath the canopy in a pocket, and deployed in a similar manner to the front shield. The rear shield is used to substantially cover the rear side of the adult mobility device frame. When the front and rear shields are both deployed, a passenger is completely enclosed within the adult mobility device and thus protected from the environment. 
         [0013]    In addition to protection from the environment, the adult mobility device also includes a variety of comfort options. A seat support incorporates several padded seat designs, adjustable head rests, and neck support options. A shock absorbing system is incorporated which is obliquely aligned to provide for maximum comfort. For persons with specific or particularly painful back problems, an optional detachable and adjustable lumbar support device may be mounted to the seatback. Persons dependent upon respirators or other respiratory aid devices have the option of storing an oxygen tank or other medical equipment in specially designed seatback pockets. The seatback is adjustable and configured to recline into a variety of positions to maximize comfort. Armrests reside on each side of the frame and may incorporate a basket-type cup holder for storing beverages. An optional tray attaches over the armrests. Furthermore, the foot rest folds up to enable a passenger to stand in close proximity to the seat when sitting down and standing up. A flexible storage compartment resides in back of the footrest and is integrated into the base of the adult mobility device frame. This storage compartment compacts when the adult mobility device frame is collapsed. An optional wire or mesh basket can be secured to the handle for shopping or additional storage. 
         [0014]    All of the features are combined along with the significant ability to present a device that is collapsible and is lightweight enough to be transportable without special equipment or attachments. 
         [0015]    The above and other objects and the nature and advantages of the present disclosure will be more apparent from the following detailed description of certain specific embodiments thereof, taken in conjunction with the drawings, wherein:

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0024]    As shown in the exemplary drawings for purposes of illustration, the present disclosure for an adult mobility device is referred to generally by the reference numeral  1 . 
         [0025]    Device  1  comprises of 7 main component structures, 1) Frame, 2) seating means, 3) tray, 4) wheels and power and braking systems, 5) rear mounted accessories, 6) ride smoothness means and 7) canopy. These will be explored in detail in the following paragraphs. 
         [0026]    The frame is comprised of a parabolicly or “U” shaped lower frame section  11  and a parabolicly or “U” shaped upper frame section  12  being joined by transverse frame member  10 . All frame sections are generally constructed from a lightweight and durable material such as heavy gauge nylon, fiberglass, composites, heavy gauge vinyl, aluminum, or other suitable materials meeting such criterion and would be tubular in nature. Lower frame  11  is a “U” shaped member and is the platform upon which are mounted the mobility means, shock absorbing member attachment  110  and foot rest  9 . In this invention, the mobility means consists of 2 front wheels  4  and at least 1 rear wheel  5 . Front wheels  4  are located in the front of the device, front being described as the direction in which the rider is facing during the principal amount of time while in the device. Rear wheel  5  can be single or dual in nature as shown in  FIG. 2 . In this invention, the best mode for practicing this invention was having two sets of rear wheel  5  which are swivelably mounted on the rear portion of the “U” shaped lower frame  11 . Rear wheels in this invention are mounted onto shaft  51  which transects the frame and are attached whereby the wheels are capable of pivoting or swiveling allowed the caregiver more easier steer the device. Having the turning wheels smaller than the front wheels and being closer to the source of propulsion allows for less energy expended to maneuver the device, in contrast to most wheelchairs where the larger tires are located in the rear and the turning or steering wheels are located at the front of the wheelchair. This makes it difficult for the caregiver to turn the chair in tight circumstances. In this invention, the front wheels  4  are larger than the rear wheels, 
         [0027]    Front wheel  4  is rigidly attached to frame section  11  independently and at opposite open ends of the “U” shaped section  11 , said attachment  45  allowing the wheels  4  to rotate freely thereabout the axis of rotation of attachment  45  and each wheel  4  is independent of the other. Positioned attachment  45  and wheel  4  is braking means  41 . In this invention, a disc brake rotor  44  is used, which is vented and has multiple cutout circumscribed thereabout the surface allowing for a reduction of weight while maintaining a size necessary to accommodate a set of brake pads  43  to apply a sufficient amount of pressure. A larger surface area of the rotor will aid in the smooth acceleration of the device as the moment of inertia of the larger disk creates a slower acceleration which is more comfortable for the rider and also becomes inertia so that the caregiver needs less energy to propel the device once in motion. The width and composition of said front wheels  4  are such as to provide a smooth comfortable ride and enable the device to be mobile over a wide range of surfaces, especially softer materials such as sand and loose dirt. Front wheels  4  can be equipped with a surface or fitted with an extra circular extension (not shown) that will enable the rider to move the device without the aid of a caregiver. An embodiment of this invention is the addition of power bar  15  as seen in  FIG. 1  and  FIG. 4C . Power bar  15  acts with ratcheting hub  152  much with the same mechanical action of a socket wrench. In these Figures, the power bar  15  is located on the right side of the device but location is dependable on the rider&#39;s preference. Teeth within hub  152  engage with the power bar when the power bar is extended and cause the wheel  4  to turn as the power bar is moved back to the original position. The rider reciprocates bar  15  up and back ambling the device forward or rearwards depending on whether biasing button  151  is engaged or not. 
         [0028]    Motion resistive means  41  is disclosed as that means which will prevent the motion of device  1  absent it&#39;s positive displacement relieving such resistance to motion. In this invention, motion resistive means is disclosed as a braking system  41  which is designed so that maximum closure of the brake pads  43  upon the rotor  44  is accomplished when the device is at rest and the caregiver nor the rider is applying any force to the brake release mechanisms  42  or  46 . Brake release means  46  is located inside of and along caregiver&#39;s handle  3 . In this invention, brake release mechanisms are caliper style brake levers which when activated cause a tightening of the caliper cables thereby releasing the pressure of pad  43  upon rotor  44 . It is an object of this invention to create a brake release mechanism that is capable of providing a range of pressure release, rather that a distinct engage/disengage of a pin and socket style of brake. It is within the scope and spirit of this invention that other means of controlling the release and regulation of the amount of release upon the pad  43  can be developed or are currently designed. Pads  42  are caused to have pressure upon rotor  44  through either manually adjusted spring tension or hydraulic fluid pressure. The braking means  41  can also be controlled through a rider controlled release in an embodiment best shown in  FIGS. 4B and 3A . The rider is capable of using rider brake release  42  in the same manner as the caregiver. It is shown that the release  42  is on the left side of the rider, but this location is transferable to either side and any location. It is preferable that release  42  is on the side opposite of power bar  15 , should that embodiment be present as well. 
         [0029]    Foot rest  9  is pivotivally attached about the ends of lower frame  11 . The pivoting of the foot rest allows for retraction when the user is wanting to stand, using the device for support and also pivots out of the way when the device is collapsed. Foot rest  9  can be padded to increase the comfort of the rider or can be removed completely based upon the desires of the rider. The pivoting of foot rest  9  is restricted so that it can not be more than parallel with lower frame member  11  and the ground, yet is capable of at least 180 degrees of freedom when pivoted rearwardly. 
         [0030]    Located between where shaft  51  transects the frame  11  and the open ends of the “U” frame are attached shock absorber attachment means, located along the interior side of frame  11 , each attachment have been placed on either side of the interior of the “U” shaped frame  11 , each one equally distant from the open ends of said frame  11 . In this invention, the shock absorber attachment means are cylindrical posts  110  that interrelate to the hollow bore located at the distal end of absorber body  111 . Attachment means can widely vary and the only criterion required is that the post and bore arrangement be such as to allow the shock absorbing means to rotate thereabout as necessary without impingement. 
         [0031]    Upper Frame  12 , which is also “U” shaped, is created at the level normal to the riders natural elbow height, and serves as the member the upholds the seat back  7 , head rest and handle assembly  17  and  3 , the material containment means  6 , the medical aid holder  126 , armrests  123  and tray  8 . Tray  8  adjustably slides into the open portion of the “U” shaped frame  12 , where detented spring engaged balls are located through adjustment means  121  as detailed in  FIG. 3A . Tray  8  is completely detachable as seen in  FIG. 6 .  FIG. 2  shows an embodiment of the flat tray common with this style of wheelchair.  FIG. 2  shows that tray  8  can be embodied to have food recess well  81  and recessed cup holder  82 , as examples of the multitude of options available to comfort and entertain the rider. The tray  8  also serves as a containment means for the rider in a manner similar to that of the tray in a baby&#39;s high chair. Tray  8  can serve as an arm rest and storage container for items such as the canopy  13 . 
         [0032]      FIG. 2  shows armrest  123  located on the right side arm of member  12  but can be located on either or both side. Immediately interiorly adjacent to armrest  123  is material containment means  6 . In this invention, open wire baskets are located on either side of and are contoured to match, seat back  7 . There is a myriad of possibilities where one can envision particular styles and types of material containment means, and this invention only discloses one, wire baskets. Centered on the exterior of the vertex of the “U” shaped member  12  is the medical aide holder  61 . This holder  126  is shaped to accept an oxygen bottle  127  in this invention but this holder  61  can be designed to fit a variety of aids, whether for respiratory devices or monitors, this invention embodies an oxygen bottle for use of the rider, or for the caregiver for that matter. Holder  126  is designed to keep bottle  127  in a nearly perpendicular plane as shown in  FIG. 3  but other device may require a different orientation. An additional feature is the catheter bag holder  129 , as people who are generally in need of this device are usually incontinent requiring a means for them to be comfortable and sanitary, 
         [0033]    Head rest assembly  17  protrudes in a vertical plane centered about the vertex of the “U” shaped member  12 , and handle assembly  3  are attached to head rest assembly  17  through handle attachment  31 . Handle attachment  31  allow handle  3  to be rotatably attached to assembly  17 , rotating about the central axis of attachment  31  providing the caregiver with a preferred angle of use, while also allowing the handles to rotate nearly 180 degrees from the in use position to the collapsed position as shown in  FIG. 7 . Head rest assembly  17  also provides for the placement of medical bag holder  2  at a position of greatest height, allowing the gravity feed of medications, food or liquids. In this invention, head rest assembly  17  has two posts creating a rectangular frame upon which the handle assembly  3 , holder  2  and head rest attachment  171  are attached. One skilled in the art would recognize that other frame shapes or singular post design could be adapted to this application. Head rest  75  is detachably attached to head rest attachment  171  centered about the vertex of the frame  12 . Handle assembly  3  also contains brake release mechanism  46  as seen in  FIG. 2 . The caregiver, through the natural position of their hands about the rounded part of the sickle shape handle  3 , can easy manipulate the mechanism  46  which variably relaxes the pressure on the brake pads  42 . As stated previously, handle  3  can be rotated throughout a range of motion about the axis of attachment  31 , allowing for a comfortable angle which the caregiver creates as they amble the rider over various terrain. An embodiment includes a position control selector  32  which inhibits the rotation of the handle  3  about the axis of rotation, thereby preventing the over rotation of the handle during use. 
         [0034]    Frame member  12  takes it&#39;s rearward shape from the contour of seatback  7  which is the shell upon which seatback cushion  71  is fitted. At the top portion of seatback  7 , head rest  75  is centered thereupon and the lower portion of seatback  7  is pivotally attached to seat bottom  6  through the interface of seatback bracket  82  and seat bottom connector  81 . Integral to cushion  71  are rectangular back slots  72  as detailed in  FIGS. 1 and 2 . The number of slots in this invention is two, but that does not limit their function, size, shape or function. The purpose of slots  72  is to facilitate the mounting of devices, cushions or other posture related items that will assist the rider in comfort. In this invention, lumbar support cushion  73  is fitted so that it&#39;s posts will fit through the slots for rearward attachment. Other cushions can include thoracic supports and pelvic and sacral bladders. It is the scope of this invention to include those therapeutic or support members, including braces, pillows, cushions and bolsters that are used to support and position the rider in greatest comfort, and allow the members a location where they can located and secured. 
         [0035]    Transverse frame member  10  connects upper frame member  12  and lower frame member  11 , through a permanently secure angled abutment between the proximal end of member  10  to upper frame member  12 , as seen in  FIG. 3A , and a pivoting bracket  112 , as seen in  FIG. 7 , conjoining the distal end of member  11  to the ends of lower frame member  11 . Transverse member  10  anteriorly contains post  64  and slot  101 , as seen in  FIG. 3A  which function as the seat  6  adjustments, as they respectively interface with horizontal displacement rail  61  and shock absorber head pin  114 . 
         [0036]    The ride comfort means consists of at least a pair of shock absorbing members consisting of shock absorber body  111  having a distal end rotatably attached to post  110 . The proximal end of body  111  is terminated in shock head  115 . Prior to the attachment of head  115  onto body  111 , spring  112  is placed into the interior of body  111 . Spring  112  must have the resiliency sufficient for the weight of the rider and the device, but not so much as to create a bumpy ride whereby the resiliency of the spring is not overcome by the weight of the rider. Head  115  contains slot pin  114  and adjustment knob  113  as seen in  FIG. 3B . Slot pin  114  rides in the interior slot  101  of transverse member  10  which sets the height of the total chair. The user twists knob  113 , loosening or tightening the interference between pin  114  and slot  101 , allowing for the device  1  to pivot and collapse. It is critical that the angle of the ride comfort means not be perpendicular to the seat  6 , as it will translate surface irregularities directly to the rider rather than the frame. The ride comfort means should be held at an oblique angle, preferably an acute angle between the lower frame member and the means itself. Horizontal displacement rail  61  is located on the left and right edges of the underneath side of seat  6 , rail  61  interfacing with post  64  located on the anterior side of transverse member  10 . Rail  61  contains 2 or more post capture slots  62 . The user is able to lift the seat  6  and slide it either towards the front or rear of device  1  and capturing post  64  into one of slot  62 , thereby adjusting the relation between seat  6  and seat back  7 . The upper side of seat  6  can be cushioned and/or contoured for rider comfort as seen in  FIG. 2 . An embodiment includes the strap slots  69  in through the seat, whereby a strap can be included which would safely secure the rider into the device  1 , said straps being similar to the seatbelts on cars. 
         [0037]      FIGS. 5 and 5A  show the addition of a canopy  13  which extends over a frame that contains one or more canopy supports  131 , said supports terminating in a frame support  132 , which is attached to upper frame member  12 . Canopy  13  is designed to protect the rider through inclement weather, and in this description extends all of the height of canopy supports  131 , whereby the canopy extends to below the foot rest  9 . Canopy  13  extends past the head of the rider extending to a point whereby the caregiver has access to handles  3 . Canopy  13  is designed of a breathable fabric with clear viewing portals, yet sturdy enough not to be effected by wind and rain. 
         [0038]    Device  1  is designed to be collapsible.  FIG. 7  shows a collapsed device  1 . The user releases the shock absorber head, allowing pin  114  to slide downwardly along slot  101 . As transverse frame member  10  pivots about the end of lower frame member  11 , the seat will pivot about the interface between post  64  and capture slot  62 , and the footrest will pivot about it&#39;s connection  123  with lower frame member  11 . 
         [0039]    A variety of modifications and improvements to the adult mobility device of the present disclosure will be apparent to those skilled in the art. Accordingly, those skilled in the art will appreciate that such changes may be made without departing from the underlying principles of the present disclosure. The above-described disclosure is not intended to limit the scope of the invention. Accordingly, the scope of the present invention is determined only by the following claims.
