Guide device for ambulatory assist device and method

A guide device providing a dimensional and ornamental guide that, engaging a leg of an ambulatory assist device used by a person, provides walking assistance, including a boot leg or sleeve for joining about a portion of the leg of the ambulatory assist device and receiving a resilient body axially for dimensional extents and receiving a guide member having a bottom glide surface for contact with a floor surface. A method of facilitating guidance of an ambulatory assist device is disclosed.

TECHNICAL FIELD

The present invention relates to ambulatory assist devices and methods. More particularly, the present invention relates to a guide disposed on a leg of an ambulatory assist device for facilitating walking by a person using the ambulatory assist device.

BACKGROUND OF THE INVENTION

Older individuals, and some younger persons as well, may experience difficulty in walking and maintaining balance while walking. This may occur as muscles and joints tighten in older individuals, or may result from injury or surgery. Walking for such persons becomes a problem, and stepping actions of raising and lower of feet sometimes becomes a shuffling movement during walking. Such persons are benefited physically and mentally by continuing involved activity with others and with walking as required for movement between bed and bath, dining rooms, and outside activities. Persons may assist, such as by holding arms as a support on which to lean.

Physical equipment providers have addressed the need for support apparatus to assist with individuals who experience difficulties with walking and standing. The ambulatory assist devices include motorized movement vehicles, canes, and four-legged walking devices that are commonly referenced as “walkers”. The four-legged walking devices include handles for gripping and front and back legs extend from the handles to the ground for support. Often the distal ends have caps on the ends that contact the ground. The front legs in some embodiments include wheels or rollers, for facilitating the walking of the user.

While such walker ambulatory assist devices assist with the walking actions of the person, there are drawbacks. Persons with problems of walking and balance may move into walls and furniture while walking even with use of an ambulatory assist device. The wheels may make the ambulatory assist device move more quickly than the person being supported may be capable. Caps made of rubber may be relatively stopped by certain types of floor surfaces, and the person being assisted may stumble relative to the ambulatory assist device.

Accordingly, there is a need in the art for an improved guide device attachable to a leg of an ambulatory assist device and method to facilitate walking use of the ambulatory assist device by a person. It is to such that the present invention is directed.

With reference to the drawings, in which like parts have like reference numerals,FIG. 1illustrates in perspective exploded view a guide device20in accordance with the present invention for engaging a leg of an ambulatory assist device. The guide device20comprises a boot leg or sleeve22for joining about a portion of a leg of an ambulatory assist device (not depicted inFIG. 1). A resilient body24axially mounts to the sleeve22and receives a guide member26having a bottom glide surface28. In the illustrated embodiment, the body24is a unitary foam material molded member that incorporates a shape-defining body and a resilient layer material as a liner rather than such body in an alternate embodiment being two separate members—a shaped body and a liner that join together to define the body24.

The guide member26in the illustrated embodiment is a cylindrical member. The guide member26has an open end30and an opposing closed bottom32. The bottom32defines the outside bottom glide surface28for gliding contact with a surface, such as a floor, walkway, yard or the like, during use an ambulatory assist device20, as discussed below. The guide member26defines an inner well37closed by the bottom32. A flange34, or collar, extends radially from an outer surface of the guide member26intermediate the open end30and the bottom surface28. The flange34preferably is proximate and spaced-from the bottom26and thereby is relatively remote from the open end30to define a perimetrical wall36extending in a direction, preferably perpendicularly, therefrom. The perimetrical wall36defines the cup-shaped configuration of the guide member26that fits onto the lower end of the sleeve22and the peg leg of the ambulatory equipment. An upper surface of the flange34defines a seat38. The inner wall of the guide member26defines a groove40proximate and spaced from the bottom26, for a purpose discussed below.

The resilient body24in the illustrated embodiment comprises a member50having an exterior surface52and opposing upper and lower planar surfaces54,56. The exterior surface52of the body24accordingly defines a dimensional extent for a obstructions contact surface as discussed below. The surface52tapers arcuately from an equatorial portion to the edges of the opposing planar surfaces54,56. The body24defines a axial passageway58open in the opposing planar surfaces54.56. In the illustrated embodiment, the passageway58has a first diameter60in a portion from the upper surface54to a first transition62, a second diameter64therefrom to a second transition66, and a third diameter67therefrom to the opposing lower planar surface56. The upper surface54defines a first annular recess68. The lower surface56defines a second annular recess70.

The resilient body24in the illustrated embodiment comprises a foam material molded to define the dimensional extents of the exterior surface52and passageway58. The body24thereby incorporates the liner as a unitary member. An alternate embodiment provides a body member to which the liner attaches, such as with adhesive, bonding or overlayment, to define the exterior surface. The liner preferably comprises a resilient material. The exterior surface52may gainfully include an ornamental design, text or graphic, such as a sports image, name or the like. In alternate embodiment, the resilient body24assembles from opposing hemispheric members that attach together about the sleeve22, for example, the hemispheric members define aligned opposing passages that receive a pin for mechanically connecting the members together to define the body24. Alternatively, the hemispheric members adhesively attach together about the sleeve22.

The sleeve22in the illustrated embodiment comprises a pair of opposing matingly engagable shells80a,80b. The shells80a,80bare longitudinally extended semi-circular mirror-image members. A flange82extends outwardly radially from a first end83. The shell80defines in a first portion84an inner wall of a first radius and a second portion88of a second radius. The first radius is less than the second radius. The transition between the first and second radius corresponds with the first transition62of the passageway58. The length of the first portion84thereby is the same as the length of the passageway58from the recess68to the first transition62for seating the shell80within the passageway58with a surface thereof contacting the shell. The second portion88defines an accurate groove92inwardly of an end of the shell80. A flange94having a tapering surface extends radially from the inner wall towards a longitudinal axis of the shell80. This defines a semi-circular open end of the shell80.

The mirror image shells80matingly engage to define the circular sleeve22. In the illustrated embodiment, the shells80have opposing longitudinal edges. A first edge defines a first mating member of a first characteristic and the opposing second edge defines a second mating member of a second characteristic. The first and second characteristics enable the separate detached shells80to detachably engage selectively together. In the illustrated embodiment, the shells80are equipped with mechanical engagements of the first and second mating members, configured to connect together such that the shell80aas first piece and shell80bas a second piece attach together to form the shell22or boot leg received on the leg of the ambulatory equipment. In the illustrated embodiment, the mechanical engagements comprise at least two spaced-apart fingers96defined on the first edge and the at least two spaced-apart slots98defined proximate the second edge. Three spaced-apart fingers and slots are illustrated. The fingers96extend as tangs from the inner wall. The spacing of the fingers96and slots98are the same, so that the fingers96of the shell80aalign with the slots98of the opposing shell80b, for mechanically detachably engaging the shells as a sleeve or boot leg around a leg of an ambulatory assist device, as discussed below.

FIG. 1Aillustrates in detailed perspective view one of the fingers96of the shell80b. A first one of the longitudinal edges of the shells80includes a longitudinal tongue97extending therefrom spaced outwardly from the inner surface of the wall to define a step99. The finger96extends laterally relative to a gap in the tongue97. A distal end of the finger96defines a projection101on the side of the finger. The second longitudinal edge of the shell80adefines a projecting distal portion103with a recessed seat105laterally thereof for receiving the tongue97as a tongue-and-groove connection when the shells80a,80bjoin together. The slot98aligns with the finger96. A stop107extends in the wall across the slot98. The projection101enters the opening of the slot98and contacts the stop107to hold the finger96in the slot98.

In the illustrated embodiment, the first portion84defines a pair of spaced-apart openings100. The openings100correspond to conventional height adjustment openings typically spaced-apart in the wall of the leg of the ambulatory assist device to which the guide device20attaches. The openings100enable a spring-biased pin in the leg to project outwardly of the leg into the opening. The pin in the leg extends through a respective opening in the leg for selectively positioning a telescoping member of the leg for adjusting the height of the ambulatory assist device for the particular person, while the guide device20is positioned on the leg of an ambulatory equipment. In yet another alternate embodiment (not illustrated), the shells of the sleeve have abutting opposing edges and a band received around an exterior holds the shells together. The band may be elastic, have an adhesive surface for attaching to the shells, or connectors on opposing ends for securing the band around the shells.

The second portion86defines in the side wall a U-shaped slot102, to provide a flexibly bendable flag104in the side wall. A nub106projects outwardly from an outside surface of the flag104, as shown inFIG. 2. During installation of the glide member26into the guide device20, the groove37of the glide member26receives the nub106to mechanically connect the glide member to the sleeve22.

FIG. 2illustrates in perspective exploded view the sleeve22of the guide device20illustrated inFIG. 1during installation on a leg110of an ambulatory assist device. The leg110typically is a cylindrical metal tubing and conventionally includes a plurality of spaced-apart openings112aligned longitudinally. A spring-biased pin conventionally selectively occupies one of the openings112for setting the length of the leg110relative to the telescoping tubes that define the leg. A distal end of the leg110receives a cap114, such as a mushroom cap typically included on ambulatory assist devices. Often, the cap114includes an annular flange or projecting portion about a bottom portion of the cap. Alternatively, the sleeve22attaches to a leg without the cap114such as a cane, walker, or other ambulatory assist device.

As discussed above, the sleeve20in the illustrated embodiment comprises the matingly engageable shells80a,80b. The shells80are depicted inFIG. 2in an “open” configuration during installation and for mechanically engaging together positioned over a lower end of the leg110of an ambulatory assistance equipment (e.g. walker peg leg). The shell80areceives the leg110with the cap114within the second portion88. The flange of the cap114, if existent, occupies the groove82. The shell80bthen engages the shell80b. The fingers96of one shell80align with the slots98of the opposing shell. The installer then pushes the shells80together sandwiching the leg110and mechanically engaging the respective fingers and slots to engage the shells80a,80btogether as the sleeve22on the lower portion of the leg110, as illustrated in perspective view inFIG. 3.

In an alternate embodiment illustrated in partially cutaway, side elevational view inFIG. 2A, the sleeve22comprises a unitary tubular member180slidingly received on the leg110. The glide member26positions over the lower end of the sleeve180and the body24is depicted exploded away in alignment, awaiting sliding engagement over the peg leg110and sleeve180, in accordance with the instant disclosure. The member180in the illustrated embodiment defines inwardly projecting ridges or spaced-apart nubs182that bear against the wall of the leg110. In an alternate embodiment, one of the nubs182engages one of the height-adjusting openings in the leg110. In an alternate embodiment, a pin extends through an opening in the tubular member180for securing as the sleeve to the leg110, for subsequent receiving of the body24.

It is noted in reference toFIG. 2, that the shells80in certain embodiments include a notch116in the flange82, which notch116aligns with an opening112in the leg110through which the pin member of the leg may be received depending on positioning of the pin in a selected one of the leg openings for setting the length of the leg110for use of the ambulatory assist device by a user. Also illustrated inFIG. 2, the flange82includes a protruding tab118, which tab is received in a notched portion of the recess68of the body24. The tab118assists with restricting rotation of the body24relative to the leg110.

FIG. 3illustrates a plan side view of a multi-component (i.e. two piece) boot leg or sleeve22component of the ambulatory assistance device20, showing the sleeve22in a “closed” configuration around the walker peg leg110. The sleeve80bis configured with height adjustment holes100to accommodate the height adjustment component in the walker/ambulatory equipment. Further, in the “closed” configuration the sleeves80a,80bfit around the walker peg leg110, wherein the mechanical engagement portion on the first piece or sleeve80ais illustrated in the mechanically engaged/attached position with the mechanical engagement portion of the second piece or sleeve80b.

The passageway58of the resilient body24aligns with the sleeve22with the upper planar surface54facing the sleeve. The installer moves the resilient body24relative to the sleeve22, such as pushing the resilient body towards the sleeve or moving the leg110to push the sleeve into the passageway. The sleeve22enters the passageway58and with continued movement (FIG. 4B) moves longitudinally through the passageway until the flange82seats in the recess68. As the flange82seats in the recess, a distal end of the sleeve passes into the portion of the passageway58. There is a gap between the wall of the passageway and the wall of the sleeve22. The exterior surface52of the body24defines a dimensional extent beyond a plane defined by an exterior surface of the leg110, for a contacting and guiding surface as the ambulatory assist device is used by person while walking, for example, past obstructions such as walls and furniture.

With reference toFIG. 5, the guide member26seats in the lower portion of the resilient body24by insertion through the open end of the lower planar surface56. The wall36of the guide member26extends into the gap between the wall of the passageway58and the wall of the sleeve22. The sleeve22thereby passes into the well37to the bottom26. The upper edge of the wall36contacts the second transition66and the flange34seats in the recess70. During installation of the glide member26, the groove37receives the nub106projecting from the outside wall of the sleeve22to mechanically connect the glide member26to the sleeve22and resist the glide from coming off during use. The insertion of the nub106into the groove37provides a “clicked-in” feedback.

FIG. 6illustrates in cross-sectional side elevational view of the guide device20engaged to the leg110of the ambulatory assist device with the guide member26exploded away in preparation for positioning the guide member in the passageway58as discussed above in reference toFIG. 5.

With reference toFIGS. 1 and 5, the guide device20engaged to the leg110provides the resilient body24in the illustrated embodiment on the lower portion of the leg. The resilient body24provides a contactable surface that is distal from the leg110. The contact surface provides a bumper or cushioning for guiding the movement of a person using the ambulatory assist device equipped with the guide device24. During walking movements, the user may walk close to a wall or furniture. The surface52provides the dimensional extent of the resilient body24and contacts obstructions such as a wall or furniture surface first rather than the leg110contacting or hitting the wall or furniture, and thereby assists or guides the user away from or along the obstructions. Also, the glide surface28slidably moves along a floor surface as the user walks with the aid of the ambulatory assist device.

FIG. 7illustrates an alternate embodiment of the guide device20featuring a light source120mounted in the body24with a power supply122and a control mechanism124for selectively operating the light source120. Light emitted from the light source120illuminates an area local thereto, for example, to illuminate in front of the guide device20. In one embodiment, the light source120angles upward at an oblique angle, (e.g., at an angle of about 30 degrees with respect to a horizontal plane that intersects the glide surface28) for optimum projection of light. The beam of light extends ahead of the guide device20to illuminate the forward and adjacent area so the user of the ambulatory assist device may more safely walk at night and/or in a dark environment. The light source120has two states (ON and OFF). In one embodiment, the light source120is manufactured by M.L.S. ELECTRONICS CO. (model number MCP12) and includes a light emitting diode (LED) (model number PK100), with an LED holder (model number PK101A) and an LED lens (model number PK102A). In one embodiment, the control mechanism124is manufactured by EASTAR INDUSTRIES LIMITED (model number MCP10) and includes the power supply122and control circuitry (model number ES33). In one embodiment, the light source120, power supply122and control mechanism124are enclosed within the molded body24; in an alternate embodiment, a cover (not illustrated) permits selective access thereto, for example, for replacing the power supply periodically. Electrical communication wires couple the electrical energy from the power supply120to the control mechanism124and the light source120. In one embodiment, the power supply120is a lithium battery disposed in a battery holder. The guide device20further alternatively includes a switch for selective activation of the light source. The switch may be on/off slide, push button, or lever switch device for selective operation. Alternatively, the switch comprises a motion detection sensor, whereupon sensing motion, the control mechanism124communicates electrical current from the power supply122to the light source. The control mechanism124may be configured for supplying electrical current for a predetermined period subsequent to the signal from the motion detection sensor of detected motion. Thus, the light remains on for period if the user stops moving with the ambulatory assist device, such as standing without movement or becoming seated.

Alternatively, in another embodiment, the control circuitry of the control mechanism includes an integrated circuit (model number ES6115) and a capacitor (model number ES442) manufactured by EASTAR INDUSTRIES LIMITED. However, the control circuitry may include any suitable circuitry, such as an ASIC, a microprocessor, a circuit board, a battery, and the like. The control circuitry determines when to turn the light source120ON and OFF given the control signal from the motion sensor.

In a further embodiment, a light sensor126mounts in the body24, to detect the amount of ambient light adjacent the guide device20. In one embodiment, the light sensor126is manufactured by SEN TECH COMPANY LIMITED (BRAND: KRC) (model number KR16) and includes a Cadmium Sulfide (CdS) sensor (model number STC551), a sensor holder (model number WT1) and a sensor lens (model number WT2). The light sensor126outputs a signal indicative of the amount of ambient light sensed. The output of the light sensor126couples to control circuitry of the control mechanism124. The control circuitry determines whether to turn the light source ON when the motion sensor detects motion of the ambulatory assist device equipped with the guide device20by comparing the signal indicative of the amount of ambient light sensed with a predetermined threshold. When the sensed light is above the threshold, the light source is disabled (whether the ambulatory assist device is in motion or not). When the sensed ambient light is below the threshold, the light source120is activated upon sensing motion. In this way, the battery life of the power supply is extended by not activating the light source120when the light is not needed, i.e., when there is sufficient ambient light adjacent the ambulatory assist device for use by the person for walking.

In a further embodiment, the control mechanism124includes a selector (not illustrated) for selecting a mode of operation, such as OFF, Auto ON and ON. The selector may include a switch, a thumb wheel, a dial, a plurality of buttons or other suitable means for selecting an operating mode. The OFF mode includes disabling the light source120such that no power is used. In this mode, the guide device20functions as normal, non-lighted guide for walking with the ambulatory assist device. The Auto ON mode includes enabling the motion sensor and the light sensor. In this mode, the guide device20functions as explained above for guiding the walking of the user, with the light source120activated only when there is motion of the ambulatory assist device equipped with the guide device20and the sensed ambient light is below the threshold level. The ON mode includes enabling the motion sensor such that the light source120goes ON anytime motion is detected. As noted above, the control mechanism124may maintain the light source120in the ON state for a period of time after motion stops.

FIG. 8illustrates a wrap or cover130configured from a sheet of material, such as a fabric or other pliant flexible sheet, for an enclosing wrap received on the body24. The cover130includes a first open end132and an opposing open end134. The open end132is sized for passage of the leg110and the open end134is sized for exposing the glide surface28of the glide member24for gliding contact during use of the ambulatory assist device by person walking on a surface. The open ends132,134may be configured with an elastic band135(shown in cut-away view) for partially closing the opening during use as a covering for the body24. Further, a side opening136selectively opened and closed facilitates installation of the cover130onto the body24. The side opening136may include closure devices such as a zipper138, matingly engagable fabric members (such as opposing VELCRO patches), button and aligned button hole in the opposing edge portions, or the like. The sheet may include ornamental decorations, patterns, colors for selective customization of the appearance of the guide device24by the user. Although not illustrated, the cover130may alternatively include character indicia including eyes, nose and mouth, of a character, animal, fantasy character, or other such appearance.

FIG. 9illustrates an alternate embodiment in which the guide device20further includes a sound emitting speaker140operatively connected to a source means142of audio signals for being communicated as to sound. In one embodiment, the source means142comprises an electronic device having a digital memory configured for storing audio signals and a controller for operating the electronic device for selective playback and emitting the sounds through the speaker140. In an alternate embodiment, the source means142comprises an electronic signal/mechanical port that engages a wired cable that communicates with an exterior electronic device configured for storing and playback of electronic audio signals. For example, the electronic signal/mechanical port is a USB port selectively connected to a USB cable from a smart phone, tablet, or other microprocessor-based audio signal storage and playback device, each configured for selection and play of stored audio signals. In yet another embodiment, the source means comprises a network communications receiver, such as a BLU RAY signals receiver, for receiving audio signals and emitting such as sound through the speaker140.

FIG. 10illustrates an alternate embodiment of the body24that includes a pocket150. The pocket150attaches to the side wall or exterior surface52with closed side and bottom edges152and secures a transparent plate154to form a receiving space between the surface52and the transparent plate154. A side156of the pocket150is open for selective access to the receiving space. The user selectively may insert an ornamental sheet158through the open side156into the receiving space for display of ornamentation through the transparent plate154and thereby customize the appearance of the guide device20. The ornamental sheet158may be a graphic, text, photograph, or other ornamental indicia. For example, children may color a drawing for a relative needing to use an ambulatory assist device for walking. Such relative may thereby personalize the walker device. Alternatively, the pocket150readily attaches to the cover130discussed above.

It is to be appreciated that while the present disclosure details attaching the guide device20relative to the leg110of the ambulatory assist device, the guide device readily attaches to other frame members of ambulatory assist devices, including handle bars of roller devices, side frame members of wheel chairs, and cross-members at upper portions of conventional ambulatory assist devices such as walkers. In such application, the guide device20includes the sleeve20, a liner or body24, and alternatively the ornamental cover130, but omits the glide member26, as the assist device20is configured to circumferentially attach to frame portion of an ambulatory assist device. For example, the guide device20is received on and extends over a portion of the frame tubing of an ambulatory assist device, wherein the frame tubing of the ambulatory assist device (e.g. a portion of a four-wheeled walker, wheel chair, or the like) extends from the opposing upper and lower ends of the guide device20. In this configuration, the peg leg of the assistive device passes through the sleeve80(e.g., the sleeve shells80a,80bsimply snap around any portion of the ambulatory assist device's lower, mid or higher frame). The liner24and cover130are designed to slip over the sleeve80. In this embodiment, in order to accommodate the diameter changes of the various peg legs or frame poles from a standard walker, to a cane, to a rollator walker, etc., brackets commonly available for use on ambulatory assist equipment may be utilized in conjunction with the guide device20. Alternatively, compression components (e.g., a strip of compression foam configured with an adhesive on either one or both sides) may be disposed between the guide device20and the frame tube of the walker/wheel chair/ambulatory assist device, such that the compression component is wrapped around at least one desired portion or section of the frame of the ambulatory assist device, so as to adjust and/or replace any space deficit (i.e., in order to promote and/or provide a snug and secure fit between the guide device20and the frame of the ambulatory assist device).

More particularly described,FIG. 11illustrates an alternate embodiment of the guide device20featuring an attachment member202disposed within the shell80afor securing the guide device to an ambulatory assist device. The attachment member202is a resilient foam member having opposing surfaces with an adhesive206closed by a detachable cover sheet204. The shell80ais illustrated with two of the attachment members. The cover sheet204is detached from a first one of the adhesive surfaces206and the attachment member202attached thereby to the inner surface of the shell80a. The cover sheet204of the other adhesive surface is detached for securing the shell80ato the leg110, such as remote from the distal end as illustrated inFIG. 12for attaching the guide device24to a leg of tubular crutch210having opposing supports212attached to a central leg member214. The central leg member214receives the leg110for positioning at a selected height for the person using the crutch as an ambulatory assist device. The resilient body24(not illustrated) attaches to sleeve22as discussed above. It is to be appreciated that the body24may have an ornamental exterior or alternatively receive the ornamental cover130discussed above. The adhesive surface206of the attachment members202secures the shells80a,80bto the leg110remote from the distal end.

Similarly, the guide device24readily attaches to a walker ambulatory assist device having a wheel assembly220with a leg stem222received in a leg thereof and a wheel224conventionally attached for rotation during walking use. The shells80a,80bof the sleeve attach with the adhesive attachment members202to the leg stem222. The guide body24slidingly moves onto the leg stem222and the sleeve22, as discussed above.

FIG. 14illustrates the guide device20attaching to a cane230intermediate a handle234with a grip236at an upper end and a distal end that may include as illustrated the tip114. The sleeve22engages the intermediate portion of a cane member232. In the illustrated embodiment, the sleeve22comprises the opposing shells80a,80bthat attach to a selected portion of the cane member232. The adhesive member202secures the shells to the cane member. In this embodiment, the mechanical engagements of the fingers96and slots98supplement the connecting of the shells to the cane member.

FIGS. 15A and 15Billustrate the guide device20attaching for ornamental purposes to a handle portion of an ambulatory assist stroller240having opposing rear legs242, opposing front legs244, and a transverse support226. Each of the front legs144receives a respective handle arm248. The handle arm248defines spaced-apart openings for selectively adjusting the height of a handle250for the stroller240conventionally with a spring-biased pin that extends through a selected one of the openings. The handle248detaches from the leg244and a stem portion of the leg244receives the guide body24. The handle248then reinserts into the leg244and may be selectively positioned using the height-adjustment openings and pin. The shells80a,80bhaving the adhesive patch members202attach to a selected portion of the handle248. The resilient body24is pushed into sliding reception with the sleeve22.
