Description
- 1. Field of the Invention
- The present invention relates to mobility aids such as canes, walkers, trek poles, walking sticks, walking poles and the like, and particularly relates to mobility aids that may have interchangeable handles, shafts, and tips, and that may incorporate a collapsibility feature.
- 2. Discussion of the Related Art
- It is well understood that the present population distribution includes a disproportionately large number of people in middle age and/or approaching old age. It is also understood that this demographic has disposable income in quantities heretofore unknown, which has allowed its members to become accustomed to choices and amenities, even in medical equipment.
- As a result, when this population is faced with the disabilities that sometimes come with age, if its members have a choice between, for example, a standard cane such as those typically available at medical supply houses, and a cane having interchangeable features and convenience features, many are more likely to choose the latter, even if it is notably more expensive than a standard cane. More importantly, for many members of this generation, the provision of choices and convenience features may increase compliance with use of mobility aids when medically indicated. An increase in compliance results in a decrease in injuries caused by non-compliance.
- Mobility aids including canes, tri- or quad-canes, walkers, rollators, trek poles, walking sticks, walking poles, and others provide additional walking support to a user during recovery from an injury or medical procedure, or simply when additional support is deemed prudent. Each type of mobility aid is useful for particular circumstances but not for others, and various features are available for many different circumstances.
- For example, a person may require a standard cane with a rubber tip for walking around the house but a more sustained walk, such as a trip to the mall, may require additional support in the form of a cane with a quad-tip (a quad-cane). Likewise, different handles may suit different personalities or different circumstances. A standard cane having a rounded handle may be difficult for some users to grasp, while a T-shaped or Y-shaped handle may be better suited to different applications. Furthermore, on a trip to the supermarket, for example, the user may not need a mobility device at all since he or she typically has a cart.
- What is needed is a mobility aid with interchangeable features so that a user can construct a mobility device that is right for his or her individual preferences. Additionally, the user can interchange features as circumstances dictate or collapse the device when desired.
- A mobility aid typically includes at least a handle, an elongated shaft, and a tip. In one aspect of the mobility aid of the present invention, a plurality of handles, a plurality of shafts, and a plurality of tips are provided. The plurality of handles and tips preferably included handles and tips of different shapes, sizes, and materials so that different users can select a different handle and/or tip based on preference or changing support needs. Each handle and each tip is connectable to each of the shafts so that a user may switch out handles or tips as desired.
- In another aspect of the invention, the shaft of the mobility aid is comprised of an upper portion and a lower portion having a telescoping relationship to one another. A locking device, such as a rocking or rocker switch, is interposed between the upper portion and lower portion to maintain the mobility aid in its fully expanded position or release the two portions from one another such that they may be telescopically moved to a collapsed position, such as a half-height position for storage or to various height positions between fully expanded and fully collapsed to accommodate varying user heights.
- Preferred exemplary embodiments of the invention are illustrated in the accompanying drawings, in which like reference numerals represent like parts throughout, and in which:

FIG. 1 , amobility aid 20 in accordance with the present invention may be in the form of a cane. However, it should be noted that the features of the present invention may apply equally to walkers, rollaters, trek poles, walking sticks, walking poles, and other mobility aids.Mobility aid 20 has ahandle 22, anelongated shaft 24, and atip 26 for making contact with the ground, floor, or other supporting surface.Mobility aid 20 further comprises connection areas A, B for interchangeable connection ofdifferent handles 22,shafts 24, andtips 26. As seen inFIGS. 2-4 , a variety ofhandles 22,shafts 24, andtips 26 may be provided, each having different features and advantages. - Referring to
FIGS. 2-4 , it can be seen that eachhandle 22 includes an insertion stem 22 a for connection with an aperture 24 a ofshaft 24. Likewise, eachtip 26 includes an insertion stem 26 b for connection with an aperture 24 b ofshaft 24. -
FIGS. 5 and 6 show one embodiment of a connection betweenhandle 22 andshaft 24 of the present invention, in whichhandle 22 has a distal end that defines the insertion stem 22 a. Adetent 28 is provided onhandle 22 to adjacent insertion stem 22 a. Detent 28 is designed to match and interconnect withball retainers 30, which are in turn held adjacent toshaft 24 and connection aperture 24 a by way of a spring biasedinner collar 32. An outer,retractable collar 34 is provided aroundinner collar 32 for secure locking of theshaft 24 to insertion stem 22 a ofhandle 22. The collar arrangement releases and connects the interchangeable parts, and a similar connection may be used for the connection ofshaft 24 to stem 26 b oftip 26. - Turning now to
FIGS. 7 and 8 , a height adjustment and/or collapsibility feature of the present invention is shown and described in one of its embodiments. Shaft 24 has anupper portion 36 and alower portion 38, whereinlower portion 38 is sized to be insertable intoupper portion 36.
