[001] This disclosure relates generally to a staircase mobility system, and more particularly to staircase mobility system comprising a seat assembly configurable between a first and a second configuration so as to allow docking with a compatible wheelchair assembly.
Background
[002] Stairlift is a safety-critical staircase mobility device that is installed on staircase for use by persons with reduced mobility. Typically, the stairlift suits persons who can walk on flat ground with minimum or little discomfort but find it difficult to climb the staircase. However, wheelchair bound persons may find it difficult to use the stairlift. To use the stairlift, a wheelchair bound person need to physically shift from the wheelchair to the stairlift. Additionally, the wheelchair needs to be physically moved to a location where the person deboards the stairlift. In some cases, when the mobility of a person deteriorates, the person may need to upgrade from using a stairlift to a wheelchair lift to go up the stairs. However, such transition may be expensive in nature. Moreover, two persons may have different mobility needs – one requiring stairlift while the other requiring wheelchair lift.
[003] Therefore, it is desirable to provide an effective and efficient staircase mobility solution for easy mobility of people with reduced mobility in a safe and cost effective manner.

DETAILED DESCRIPTION
[015] Exemplary embodiments are described with reference to the accompanying drawings. Wherever convenient, the same reference numbers are used throughout the drawings to refer to the same or like parts. While examples and features of disclosed principles are described herein, modifications, adaptations, and other implementations are possible without departing from the spirit and scope of the disclosed embodiments. It is intended that the following detailed description be considered as exemplary only, with the true scope and spirit being indicated by the following claims. Additional illustrative embodiments are listed below.
[016] Referring now to FIG. 1A, a perspective view of a staircase mobility system 100 is illustrated, in accordance with an embodiment. In some embodiments, the staircase mobility system 100 may include a base assembly 102. The base assembly 102 may include a motor 104 operable by a power source (not shown). The motor 104 may be configured to drive the base assembly 102 along a guide rail 106 in a forward or reverse direction. The guide rail 106 may be configured to be installed substantially parallel to at least one of an incline of a staircase or a flat ground.
[017] The staircase mobility system 100 may further include a seat assembly 108 coupled to the base assembly 102. The seat assembly 108 may include a seat base 110 and a back support 112 slidable in a vertical direction perpendicular to the seat base 110 or pivotable about a horizontal axis. In some embodiments, a height of the seat base 110 may be slightly adjustable. The seat assembly 108 may further include a pair of armrests 126. Each of the pair of armrests 126 is pivotable about a vertical axis. The seat assembly 108 may be configurable between a first configuration and a second configuration. In the first configuration, the back support 112 may be positioned vertically above the seat base 110 and each of the pair of armrests 126 may be aligned in a first position towards the seat base 110. In the illustrated embodiment, the seat assembly is configured in the first configuration. As will be described in greater detail in conjunction with FIG. 1B, in the second configuration, the back support 112 may be positioned vertically below the seat base 110 and each of the pair of armrests 126 may be aligned in a second position away from the seat base 110.
[018] In some embodiments, each of the pair of armrests 126 of the seat assembly 108 may be aligned in the second position prior to docking a compatible wheelchair assembly 114 (shown in FIG. 2A through FIG. 4B). Upon docking the compatible wheelchair assembly 114, each of the pair of armrests 126 is configured to securely lock the compatible wheelchair assembly 114 to the seat assembly 108 by moving from the second position to the first position.
[019] As will be described in greater detail in conjunction with FIGS. 2A-2B, the compatible wheelchair assembly 114 includes a wheelchair seat base 116, a wheelchair back support 118, a pair of wheelchair armrests 120 and a set of wheels 122. Each of the pair of wheelchair armrests 120 may be pivotable about a horizontal axis between a first position along the wheelchair seat base 116 and a second position along the wheelchair back support 118. In some embodiment, each wheelchair armrest of the pair of wheelchair armrests 120 may include a first horizontal member aligned along the horizontal axis and a second horizontal member pivotably attached to the first horizontal member and pivotable between the first position and the second position. Further, the set of wheels 122 may be configured to move the compatible wheelchair assembly 114 on the flat ground. As will be appreciated, the set of wheels 122 may be in any configuration and may include a pair of front wheels and a pair of rear wheels, or a pair of two side wheels, or the like.
[020] In some embodiments, the pair of wheelchair armrests 120 may be pivoted to the second position before docking the compatible wheelchair assembly 114 to the seat assembly 108. Further, in some embodiments, the set of wheels 122 of the compatible wheelchair assembly 114 is configured to be raised or be lowered when docked or undocked, respectively, to the seat assembly 108.
[021] In some embodiment, the seat assembly 108 may include a control pad 124 accessible to a user occupying the seat assembly 108. In the illustrated embodiments, the control pad 124 may be integrated on one of the pair of armrests 126. The control pad 124 may include a plurality of input peripherals operable to generate control signals to drive the base assembly 102 along the guide rail 106. Additionally, the control signals generated using the control pad 124 may also facilitate at least a part of docking and undocking operations. The base assembly 102 may be configured to drive the seat assembly 108 along the guide rail 106 based on one of control signals received from the seat assembly 108. Alternatively, the base assembly 102 may be configured to drive the seat assembly 108 along the guide rail 106 based on remote control signals received from a remote control.
[022] Referring now to FIG. 1B, a perspective view of a seat assembly 108 of the staircase mobility system 100, where the seat assembly 108 is configured in a second configuration, is illustrated, in accordance with an embodiment. As stated above, when configured in the second configuration, a back support 112 of the seat assembly 108 may be positioned vertically below a seat base 110. Each of a pair of armrests 126 may be aligned in a second position away from the seat base 110 prior to docking a compatible wheelchair assembly 114. Further, upon docking the compatible wheelchair assembly 114, each of the pair of armrests 126 may be configured to securely lock the compatible wheelchair assembly 114 to the seat assembly 108 by moving each of the pair of armrests 126 from the second position to the first position.
[023] In some embodiments, each armrest of the pair of armrests 126 may include a vertical member aligned along the vertical axis, and a horizontal member pivotably attached to the vertical member and pivotable between the first position and the second position. By way of example, the vertical member and the horizontal member may be a hollow pipe made of plastic, metal, composite or any other material suitable for enabling smooth pivoting of the horizontal member with respect to the vertical member.
[024] In some embodiment, the staircase mobility system 100 may include a mechanically or an electrically operable latch to hold each of the pair of armrests 126 in one of the first position or the second position. Further, in some embodiments, the staircase mobility system 100 may include a mechanically or an electrically operable latch to hold the back support 112 vertically above or below the seat base 110. By way of an example, the mechanically operable latch may be a retractable bracket (e.g., in form of one or more bolt-like piece), a cam/twist latch, a hook latch, and pull down/toggle latch. Similarly, by way of another example, the electrically operable latch may include an actuating device that may operate to lock or unlock a latch in response to a control signal. The control signal may be communicated to the actuating device through a Radio Frequency (RF) or other transmitted signal or through hardwires connecting the actuating device to the control pad.
[025] The base assembly 102 of the staircase mobility system 100 may include a motor 104. By way of an example, the motor 104 may be a direct current (DC) motor where input electrical energy is direct electric current. The motor 104 may transform the input electrical energy into a mechanical rotation of a shaft. Operation of the motor 104 is powered by a power source (not shown), which may be powered by an external power supply (not shown) located at either or both extreme ends of the guide rail 106. As may be appreciated, in some embodiments, the power source may be further equipped to operate with rechargeable batteries 128 that may be constantly trickle-charged when the power source is connected to the external power supply. If the external power supply gets disconnected from the power source, the rechargeable batteries 128 may take over so as to operate the motor 104 within the base assembly 102. In such embodiments, the external power supply may be in form of a charging station. It should be noted that, in some embodiments, the power source may further power the control circuitry of the seat assembly 108, either in its standalone operation or when the compatible wheelchair assembly 114 is docked with the seat assembly 108.
[026] In an embodiment, the base assembly 102 may be configured to drive the seat assembly 108 along the guide rail 106 upon receiving control signals from the seat assembly 108 or upon receiving remote control signals from a remote control operated by a user of the staircase mobility system 100. As an example, the remote control signals may be generated from a remote control, operated by the user or an assistant, so as to automatically call or send the seat assembly 108 up and down the guide rail 106 when the user is located on a different floor than the seat assembly 108. This enables multiple users to utilize the staircase mobility system 100.
[027] The base assembly 102 may further include a footrest 134. The footrest 134 may be linked to a lever and may be raised and folded using the lever. Alternatively, the footrest may be retractable within the base assembly 102. In some embodiments, when the staircase mobility system 100 is not in use or when the compatible wheelchair assembly 114 is docked to the seat assembly 108, the footrest 134 may be folded or drawn back within the base assembly 102. Similarly, in some embodiments, when the staircase mobility system 100 is use in its original form (i.e., when the compatible wheelchair assembly 114 is not docked to the seat assembly 108), the footrest 134 may be unfolded or drawn out from the base assembly 102. In some embodiments, the folding/unfolding or drawing in/out of the footrest may be achieved based on a control signal from the control pad 124. The user may generate the control signal for folding/unfolding or drawing in/out of the footrest by using the control pad 124 that is accessible to the user occupying the seat assembly 108 or occupying the compatible wheelchair assembly 114 docked to the seat assembly 108.
[028] Referring now to FIG. 2A, a perspective view of a compatible wheelchair assembly 114 with a pair of wheelchair armrests 120 in a first position is illustrated, in accordance with an embodiment. It should be noted that the pair of wheelchair armrests 120 are pivotable about a horizontal axis between the first position and a second position. Thus, in some embodiments, the pair of wheelchair armrests 120 are pivoted to the first position along a wheelchair seat base during normal use (i.e., when the compatible wheelchair assembly 114 is not docked to the seat assembly 108).
[029] The compatible wheelchair assembly 114 includes the wheelchair seat base116. The wheelchair seat base 116 may be a wide seat with thick padding and may have a wheelchair back support 118 with variable settings as per preferences of the user. The wheelchair seat base116 may have either a vinyl or nylon covering. In addition, the wheelchair seat base116 may have a seatbelt to be used by the user during movement of the seat assembly 108 over the guide rail 106.
[030] Referring now to FIG. 2B, a perspective view of the compatible wheelchair assembly 114 with the pair of wheelchair armrests 120 in a second position is illustrated, in accordance with an embodiment. The pair of wheelchair armrests 120 are pivoted to the second position along a wheelchair back support 118 just before docking the compatible wheelchair assembly 114 on the seat assembly 108. The pair of wheelchair armrests 120 remain in the second position while the compatible wheelchair assembly 114 is docked to the seat assembly 108.
[031] Referring now to FIG. 3, a perspective view of the compatible wheelchair assembly 114 being docked to the seat assembly 108 of the staircase mobility system 100 is illustrated, in accordance with an embodiment. Prior to docking a compatible wheelchair assembly 114 onto the seat assembly 108, each of the pair of armrests 126 of the seat assembly 108 is aligned in a second position away from a seat base 110. Back support 112 of the seat assembly 108 is positioned vertically below the seat base 110. In addition, each of the pair of wheelchair armrests 120 are pivoted to a second position along a wheelchair back support 118.
[032] In some embodiments, the height of the seat base 110 of the seat assembly 108 may be slightly lowered to allow uncomplicated docking or undocking of the compatible wheelchair assembly 114 to the seat assembly 108. In some embodiments, forward or backward movement of the base assembly 102 along the guide rail 106 may be suspended until the compatible wheelchair assembly 114 is securely docked on the seat assembly 108 so as to prevent any mishap. In particular, a control on the control pad 124 for allowing movement of the base assembly 102 on the guide rail 106 may be enabled only when the compatible wheelchair assembly 114 is docked and securely locked on the seat assembly 108. In other words, the control on the control pad 124 for allowing movement of the base assembly 102 on the guide rail 106 may be enabled only when each of the pair of armrests 126 of the seat assembly 108 is aligned in the first position.
[033] Referring now to FIGS. 4A-4B, a perspective view of a compatible wheelchair assembly 114 docked and locked to the seat assembly 108 of the staircase mobility system 100 is illustrated, in accordance with another embodiment. As stated above, the compatible wheelchair assembly 114 may include a wheelchair seat base 116. The wheelchair seat base116 may be disposed over a seat base 110 of the seat assembly 108. The pair of wheelchair armrests 120 are in the second position. As stated above, the pair of wheelchair armrests 120 are typically moved to the second position before docking the compatible wheelchair assembly 114 to the seat assembly 108. Further, each of the pair of armrests 126 of the seat assembly 108 are in the first position. Again, as stated above, once the compatible wheelchair assembly 114 docks to the seat assembly 108, the pair of armrests 126 are configured to securely lock the compatible wheelchair assembly 114 to the seat assembly 108 by moving from the second position to the first position.
[034] One of the pair of armrests 126 may further include a control pad 124. The control pad 124 may be, therefore, accessible to a user occupying the wheelchair seat base116. As stated above, the control pad 124 may include input peripherals that may be operable to generate control signals to drive the base assembly 102 to perform a plurality of corresponding operations. The plurality of corresponding operations includes, but are not limited to: (a) driving the base assembly 102 along the guide rail 106 in a forward or a reverse direction, (b) driving the base assembly to adjust the height of the seat assembly 108 to facilitate docking/undocking of the compatible wheelchair assembly 114, (c) driving actuators to activate/deactivate the latches, (d) deactivating movement of the base assembly 102 on the guide rail 106 while the pair of armrests 126 is in the second position, and so forth.
[035] Additionally, the control pad 124 may be configured to be communicatively linked to the compatible wheelchair assembly 114 using any known or proprietary communication technology (e.g., Bluetooth Pairing). Once communicatively linked, the input peripherals may be operable to generate control signals to partially operate the set of wheels 122 of the compatible wheelchair assembly 114. Thus, in such embodiments, one of the operations of the control pad 124 may include raising or lowering the set of wheels 122 when the compatible wheelchair assembly 114 is docked or undocked, respectively. In other words, the user may raise or lower the set of wheels 122 when docked or undocked, respectively, using the control pad 124. As illustrated in FIG. 4A, the set of wheels 122 is in original lowered position, which may be immediately after being docked or immediately before being undocked (i.e., when the base assembly 102 is near the flat ground). Further, in some embodiments, the movement of the base assembly 102 on the guide rail 106 may be deactivated while the set of wheels 122 is in the original lowered position. This ensures that the movement of the base assembly 102 on the guide rail 106 is not obstructed by the set of wheels 122.
[036] The plurality of input peripherals on the control pad 124 may include, but may be not limited to, switches, buttons, handles, joysticks, and so forth. The input peripherals may be designed so that users with arthritis, neuromuscular conditions, and general unsteady or weak ligaments may use the peripherals without discomfort or trouble. As will be appreciated, though the control pad 124 has been illustrated to be present on one of the arms 126 of the seat assembly 108, varied options may be provided to the user to choose where the control pad 124 is to be installed. For example, the control pad 124 may be installed on both the arms 126 of the seat assembly 108 or may be installed in form of a controller flexibly coupled to one of the arms 126 of the seat assembly 108.
[037] Further, the compatible wheelchair assembly 114 is capable of being driven around on a flat surface. In particular, the compatible wheelchair assembly 114 comprises a set of wheels 122 that may be configured to move the compatible wheelchair assembly 114 on the flat ground. As such, the compatible wheelchair assembly 114 may itself include a wheelchair control pad (not shown) accessible to a user occupying the compatible wheelchair assembly 114 during its normal (i.e., undocked) operation. The wheelchair control pad may be integrated on one of the wheelchair armrests 120. The wheelchair control pad may include input peripherals operable to generate control signals to drive the set of wheels 122 on the flat ground. Additionally, the control signals generated using the wheelchair control pad may also facilitate at least a part of docking/undocking operations, such as, by facilitating movement of the wheelchair armrests 120 between the first position and the second position.
[038] As illustrated in FIG. 4B, the set of wheels 122 is in raised position, which may be during movement of the base assembly 102 on the guide rail 106 while the compatible wheelchair assembly 114 is docked and locked to the seat assembly 108. Thus, upon the compatible wheelchair assembly 114 being docked on the seat assembly 108, the set of wheels 122 may be raised or folded above a flat ground so that the set of wheels 122 do not interfere with movement of the compatible wheelchair assembly 114 along a guide rail 106. Further, prior to the compatible wheelchair assembly 114 being undocked, the set of wheels 122 may be brought to a level of the flat ground so that the compatible wheelchair assembly 114 may rest and move on the wheels thereafter.
[039] As an example, consider a home having installed the staircase mobility system 100 for use by a plurality of users with mobility challenges. One of the users say ‘John’ may be comfortable with walking on a flat surface but has challenges in climbing a staircase, and another user say ‘Jim’ may have extensive mobility challenges and cannot physically move around in the home. In this exemplary scenario, when the user ‘John’ wants to visit an upper floor of the home, he may use an already installed seat assembly on a base assembly. ‘John’ may reach out and sit on the seat assembly. He uses relevant controls on a control pad to guide movement of the base assembly so as to travel to the next floor. The controls on the control pad may transmit relevant control signals to initiate movement the seat assembly.
[040] In an additional scenario, consider another user say ‘Jim’ who is bound by a wheelchair and wants to visit to a lower floor of the home. Considering that in this scenario, the base assembly along with the seat assembly is not available on the floor where ‘Jim’ is placed but is present on another floor. In this case, ‘Jim’ may use a remote control to instruct the seat assembly to reach to the floor where ‘Jim’ is present. ‘Jim’ may then configure the seat assembly in a second configuration. In other words, ‘Jim’ may dock and securely lock his compatible wheelchair assembly onto the seat assembly by adjusting the wheelchair armrests of his compatible wheelchair assembly (from first position to the second position) and by adjusting armrests of the seat assembly (from first position to second position and then back to first position). Upon the compatible wheelchair assembly being docked and securely locked to the seat assembly, ‘Jim’ may instruct movement of the seat assembly using the control pad.
[041] As will be appreciated by those skilled in the art, the above techniques relate to a staircase mobility system. The system provides for a simple yet effective way of enabling movement of people dealing with mobility restraints. The system does away with a need for wheelchair bound people to transfer from the wheelchair to a seat on a stairlift for facilitating movement. Moreover, the system takes away the need to install a wheelchair lift and the user can work with existing installed stairlift. In addition, the system is efficient and is cost coefficient, and help easing movement of people with mobility issues.
[042] It is intended that the disclosure and examples be considered as exemplary only, with a true scope and spirit of disclosed embodiments being indicated by the following claims.
