2. Description of the Related Art
Many individuals suffer from a lack of mobility because of age, medical conditions or a variety of other factors. As a result, such individuals frequently require some type of mechanical aid or device in order to facilitate there support on or travel over the variety of different supporting surfaces. Known mobility aiding devices which are currently in use and readily available on the commercial market include walker assemblies and wheel chairs. In the former category, a walker structure allows an individual to support oneself in a stable, upright orientation, while standing or walking.
Conventional walker assemblies also allow individuals to safely traverse a variety of different support surfaces such as floors, sidewalks, streets, ground surfaces, etc. As such, walker assemblies incorporating conventional structural and operative features may include supporting wheels, rollers, etc. When present, such wheel or equivalent structures increase the mobility of a user, but may possibly reduce his/her stability, especially when all of the legs of a given walker frame include a wheel or roller structure connected thereto.
The advantages of the walker assembly of the type described above include a generally smaller, lightweight frame which may be more easily stored and/or transported when not in use. As such, conventional walker assemblies may in fact be collapsible or foldable in order further facilitate the disposition thereof within convenient or appropriate storage areas.
As set forth above wheelchairs represent another category of mobility aiding devices which are used by those individuals having more significant physical limitations. An increased use of wheelchairs has occurred in recent years, due at least in part, to an increasingly aging population. As such, the development of the wheelchair in various forms has progressed from the smaller, manually propelled wheelchair structures to the heavier, larger wheelchair assemblies which are motorized. While the more sophisticated, motorized wheelchairs have distinct advantages in terms of facilitating mobility without requiring manual exertion, cost, weight, maintenance, etc. are sometimes considered disadvantages.
Yet another category of mechanical mobility aides, which is perhaps most commonly used, includes walking canes. While it is recognized that a walking cane can be used for decorative purposes and/or as a fashion accessory, the majority of cane structures are specifically designed to be used as an aide to physically challenged individuals not requiring a wheelchair or walker assembly. However, when needed, a cane assembly should include sufficient structural integrity to allow an individual to stand or walk over a variety of different surfaces in a safe, reliable and stable manner.
It is well recognized that walking canes, walking sticks and like devices have been in use for hundreds of years and as such typically comprise a one piece elongated shaft having some type of handle or hand gripping portion secured to one end thereof. However, recently there has been an increased demand for a cane structure which is more structurally versatile. For example, there is a recognized need for a walking cane assembly to overcome any disadvantages and problems associated with known or conventional canes, such as by being at least partially collapsible or foldable into a reduced volume configuration. Such capabilities would allow the storage and transport of a cane assembly more easily and/or in a smaller area. At the same time, any structurally modified and operationally versatile waling cane assembly should be reliably stable and used to aide in the support or mobility of a physically challenged individual. However, the providing of such stability should not detract from the preferred lightweight structure of a proposed walking cane assembly.
Other features preferably associated with a newly proposed walking cane assembly should be the ability to easily and efficiently adjust its overall length in order to accommodate users of various sizes. Also when a preferred cane assembly incorporates a collapsible or foldable feature specific structural components should be associated therewith which serves to stabilize at least the elongated shaft portion of the cane when being disposed and maintained in an operative, ready to use position.
The present invention is directed to a walking cane assembly having the structural versatility to be selectively disposed between a collapsed or folded position and an operative position. Moreover, the various structural components of the various preferred embodiments of the cane assembly of the present invention are cooperatively structured and disposed to allow a certain degree of adjustability of the cane assembly. Such adjustable features include, but are not limited to, a variance in the length of the cane assembly and a selective positioning of a hand grip of the handle assembly in any of a plurality of angular orientations relative to the length or longitudinal access of the shaft. As such, the walking cane assembly of the present invention can be quickly and easily adjusted to accommodate users of different sizes, while also being readily adaptable to accommodate the personal preferences or physical demands of a user.
The selective positioning, of the cane assembly in either the aforementioned collapsed or operative positions is accomplished by forming the shaft portion thereof to include a plurality of elongated sections disposed in coaxial, end-to-end relation to one another when in the operative position. Each of the elongated sections is substantially hollow and dimensioned to accommodate an elongated resilient material cord, strap, band, etc, on the interior thereof. As structured, the interior, resilient material band exerts a biasing force on the shaft which serves to firmly maintain the elongated sections thereof in the coaxial, aligned, operative position. However, the exterted biasing force is such as to permit a separation of the elongated sections into a folded or collapsed orientation, as will be explained in greater detail hereinafter.
Reliable and stable support of a cane user, while standing or walking, is a recognized necessity. Accordingly, the structural integrity of a cane assembly used as mobility aid should be sufficient to withstand forces exerted thereon, at least in the 250 pound range. Therefore, the strength and stability of the cane assembly of the present invention is intentionally enhanced through the provision of a stabilizing assembly. The stabilizing assembly is directly associated and cooperatively structured with each of a plurality of joint assemblies. Each joint assembly is disposed and structured to removably connect the plurality of elongated segments to one another, when the shaft is in the aforementioned operative position. Moreover, the stabilizing assembly comprises two mating and or abutting stabilizing segments associated with the mating portions of each joint disposed and structured to removably connect corresponding ends of the elongated segments of the shaft in the operative position.
As set forth above, cooperatively disposed components of the cane assembly are cooperatively structured to provide for selective adjustment of both the length of the shaft and the specific angular orientation of a handle assembly. The handle assembly includes a hand grip and an elongated mounting portion which serves to removably connect the grip to the proximal end of the shaft. The connection between the handle assembly and the shaft is such as to allow the mounting assembly and the attached grip to be adjusted along the length of the shaft adjacent to the proximal end. In addition, the grip is removably secured to the outer most end of the mounting portion of the handle assembly and is preferably attached thereto by a mating, threaded connection. As such, the grip maybe rotated relative to the mounting portion as well as the shaft, when the mounting portion and the shaft are fixedly, but removably secured to one another. This rotational movement facilitates a minor adjustment in the operative length of the cane assembly by allowing the grip to rotate towards or away from the outer most end of the mounting portion.
However the rotational, threaded interconnection between the grip and the mounting portion may be considered even more significant by allowing the grip to be selectively disposed in any one of a plurality of angular orientations relative to the axis of the mounting portion, as well as the shaft to which it is removably but fixedly attached. One benefit of varying the angular orientation between the grip and the mounting portion is the ability to position or orient a connection assembly, serving to interconnect the handle assembly and the shaft, at various, less noticeable locations relative to the grip. Personal preferences of a user may thereby be accommodated.
Other structural and operative features of the various preferred embodiments of the cane assembly of the present invention comprise a surface engaging end member or “tip” which is specifically structured to add stability to a user of the cane assembly. More specifically, the surface engaging end or tip includes a peripheral flange made of a material having a predetermined flexibility and protruding outwardly from a base and or housing portion of the tip. Further, the predetermined degree of flexibility of the peripheral flange is such as to at least partially collapse when engaging a user supporting surface. A non-sliding, non-slipping engagement of the surface, by the tip and the distal end of the shaft to which it is attached is thereby accomplished, regardless of the type or texture of the supporting surface.
Therefore, the cane assembly of the present invention overcomes recognized disadvantages and problems associated with cane type mobility aides conventionally known and commonly used by the elderly and/or physically challenged individuals. Included in the various operative and structural features of the preferred embodiments of the subject cane assembly is the ability to selectively adjust its physical characteristics to accommodate the size as well as other requirements of a user. In addition, the cane assembly is capable of being selectively disposed in either an operative position, when intended for use, or a collapsed position, so as to assume a smaller volume for storage and/or transport. In addition, while the cane assembly of the present invention comprises a lightweight construction the cooperative nature of the various components of the cane assembly provide reliable stability as well as firm engagement with the surface over which the user of the cane assembly is traveling.
These and other objects, features and advantages of the present invention will become clearer when the drawings as well as the detailed description are taken into consideration.

Accordingly, the one or more of the joint assemblies 18 comprise mating portions 19 and 23 which are disposed on or connected to different ones of corresponding ends of adjacent elongated sections, such as 14 and 15. More specifically, mating portions 19 and 23 are structured to define male and female mating portions respectfully. As such, male mating portion 19 includes an elongated outwardly extending mating member having an angular, converging exterior surface 19′ which can also be defined as a frusto-conical configuration. Integrally or otherwise fixedly attached thereto is an elongated, substantially cylindrical exterior surface 19″ extending from the convergent end of the angular surface 19′ to the extremity 25 of the male mating portion 19.
As also represented the elongated sections 14 and 15, as well as the remaining sections 16 and 17 are at least partially hollow and include an interior channel communicating with open end of extremity 25′. The hollow interior of the elongated sections 14 through 17 accommodates an elongated, flexible material cord, strap band or like biasing member 28 which serves to exert a biasing, retaining force on each of the elongated sections 14 through 17. The biasing, retaining force provided by the elongated elastic material member 28 is sufficient to facilitate the retention of the elongated segments 14 through 16 in the operative position of
Moreover, the joint assembly 18 includes the female mating portion 23 having an interior, angularly and inwardly converging mating surface 23′ as well as a substantially cylindrical interior surface 23″. Further, mating surfaces 23′ and 23″ are dimensioned, disposed and configured to matingly engage the outwardly converging surface 19′ and the cylindrical surface 19″ when the mating portions 19 and 23 are brought into mating engagement with one another, as generally represented in
In order to provide reliable stability the shaft 12 when in its operative position, particularly at the locations of the joint assemblies 18, the exterior surfaces 19, 19′ and the interior surfaces 23′ and 23″ are cooperatively structured the manner described. However, additional structural features to further facilitate the stability and firm interconnection of the plurality of elongated sections 14 through 16 comprise a stabilizing assembly directly associated with each of the joint assemblies 18. More specifically, each stabilizing assembly 18 includes two stabilizing segments 30 and 32 each disposed on a different one of adjacent elongated segments, such as at 14 and 15, and in direct association with the mating male section 19 and the mating female section 23, respectively. In a most preferred embodiment, the stabilizing segments 30 and 32 comprise annular peripheral portions disposed and configured to assume abutting engagement with one another when the corresponding elongated sections 14 and 15 are in the operative position, in coaxial alignment with one another.
As should be apparent, the stabilizing segment 30 substantially surrounds the base of the converging, angular exterior surface 19′ and is located substantially contiguous to the junction of the exterior surface 19′ and the remainder of the corresponding elongated section 14. The stabilizing segment 32, associated with the elongated section 15 and the female mating portion 23, is located at the outer extremity of the converging or angularly oriented interior surface 23′. As such, when the male mating portion 19 is inserted in mating engagement within the interior of the female mating portion 23, the stabilizing segments 30 and 32 will be disposed in abutting engagement with one another as the adjacent segments 14 and 15 assume the coaxially aligned orientation, which at least partially defines the operative position of the shaft 12.

Therefore and as set forth above, the hand grip 26 is movably and removably connected to the mounting portion 22 of the handle assembly 20 and more specifically is allowed to rotate relative to the length or central longitudinal access of the mounting portion 22. Moreover, various features of the cane assembly 10, including its appearance, are enhanced by allowing the handle grip 26 to be selectively disposed in any one of a plurality of angular orientation relative to the length of the mounting portion 22 as well as the remainder of the shaft 12, such as when the mounting portion 22 and the shaft 12 are fixedly but removably connected to one another in the operative position of
In order to more precisely determine each of the plurality of angular orientations in which the hand grip 26 may be disposed relative to the length of the mounting portion 22, another preferred embodiment of the present comprises an alignment assembly. As shown in
In operation, the user selects any one of a plurality of angular orientations which the hand grip 26 is to assume relative to the mounting portion 22 and the shaft 12. When such an angular orientation is selected, the alignment segment 50, disposed on the hand grip 26, is aligned with an appropriate one of the alignment segments 52 formed on the extremity 22′ of the mounting portion 20. The annular base or ring 46 is sized to be movable along the length of the exterior surface of the mounting portion 22. As such the ring 46 is disposed adjacent to the extremity 22′ such that the protruding finger 48 extends across the junction 51 between the hand grip 26 and the mounting portion 22 and in interconnecting retaining relation with the aligned, alignment segments 50 and 52′ as represented in
Additionally, in an alternate preferred embodiment, as shown in
Selection of a particular one of the plurality of angular orientations in which the hand grip 26 is disposed may be based, at least in part, upon the orientation or positioning of the connecting assembly 38 defined by the plurality of apertures 40 and the biasing finger 42 serving to interconnect the mounting portion 22 to the proximal end 12′ of the shaft 12. By way of example, a user may prefer to dispose the connecting assembly 38 in a less obtrusive location, such as beneath the rear portion of the handle grip 26 as at 53. In contrast, connecting assembly 38 may also be located beneath the front portion of the hand grip, as at 55 and thereby face outwardly from what may be considered a front portion of the cane assembly 10. As yet another alternative, the connecting assembly 38 may be located on either side of the hand grip 26. A variety of other factors may also determine a preferred angular orientation of the hand grip 26 relative to the length of the mounting portion 20 and shaft 12.
