(22) The non-limiting exemplary embodiment(s) is/are referred to generally in FIGS. 1-9a and is/are intended to provide a multi-functional walking cane 10 for assisting a user to reach and pick up objects that may be too high or on the floor. The multi-functional walking cane 10 includes a body 11 having a cavity 12 provided with a centrally registered longitudinal axis 13, a proximal end 14 and a distal end 15 opposed therefrom, and a handle 16 disposed at the proximal end 14. An object-grabbing mechanism 17 is in operable communication with the body 11. Such an object-grabbing mechanism 17 has an object-grabbing section 18 seated exterior of the body 11. Advantageously, the object-grabbing section 18 is configured to resiliently deploy (articulate) between a retracted, equilibrium position 19 (FIGS. 1, 3-6a) and an expanded tensioned position 20 (FIGS. 7-9a), respectively, upon receiving a corresponding user input. Such a structural configuration provides the unexpected and unpredictable advantage of deploying and retracting object-grabbing mechanism 17 without adjusting a user grip of the cane 10 during a walk.

(23) In a non-limiting exemplary embodiment, an end cap 44 is removably affixed to the object-grabbing section 18 thereby providing a support to engage a ground surface during the walk while preventing premature deployment of the object-grabbing section 18. The end cap 44 can be manually removed and attached to the object-grabbing section 18.

(24) In a non-limiting exemplary embodiment, the object-grabbing mechanism 17 includes an actuator 21 extending out from the proximal end 14 of the body 11, and a shaft 22 having a proximal end 22a seated within the cavity 12 and connected to the actuator 21. Such a shaft 22 further has a distal end 22b provided with a serrated outer surface 24 (e.g. circumferential outer surface) partially seated exterior of the body 11. A resilient spring 25 is concentrically wound about the shaft 22, wherein the spring 25 is configured to compress to a tensioned position 25a (FIGS. 7-9a) and thereafter automatically decompress to an equilibrium position 25b (FIGS. 1, 3-6) when the actuator 21 is linearly displaced inwardly and outwardly from the shaft 22, respectively. Such linear displacement occurs along centrally registered longitudinal axis 13. Notably, the object-grabbing section 18 is located at the distal end 15 of the body 11 and rotatably coupled to the serrated outer surface 24 of the distal end 22b of the shaft 22. In this manner, the actuator 21, the spring 25 and the shaft 22 are contemporaneously reciprocated in sync along the centrally registered longitudinal axis 13 of body 11 such that the grabbing section 18 is pivotally displaced (articulated) between the retracted equilibrium position 19 (FIGS. 1, 3-6a) and an expanded tensioned position 20 (FIGS. 7-9a), respectively. Such a structural configuration provides the unexpected and unpredictable advantage of automatically and contemporaneously retracting the object-grabbing section 18 to the retracted equilibrium position 19 by simply releasing actuator 21 with a single metacarpal while maintaining a hand grip on the cane 10 (e.g., handle 16). There is no need to readjust the user grip or use another hand to actuate the object-grabbing section 18.

(25) In a non-limiting exemplary embodiment, the object-grabbing section 18 further includes a plurality of grabbing members 28 each having a curvilinear interior surface 29 and a drive gear 30 statically affixed thereto. Optionally, protrusions 47 may be employed to provide frictional contact with the target object. It is noted that each grabbing member 28 has a corresponding curvilinear interior surface 29 and drive gear 30. A plurality of brackets (bracket pairs 31, 31a, 31b) are fixedly connected to the distal end 15 of the body 11. Such bracket pairs 31, 31a, 31b are configured such that each drive gear 30 is intercalated between a corresponding bracket pair 31, 31a, 31b. Notably, a plurality of pivot pins 32 are transversely interfitted through the drive gears 30, respectively, and mated to the brackets pairs 31, 31a, 31b, respectively. In this manner, the brackets pairs 31, 31a, 31b are supports for stabilizing the grabbing members 28 during deployment and retraction. Advantageously, the grabbing members 28 are equidistantly and symmetrically offset from the centrally registered longitudinal axis 13. Thus, each of the drive gears 30 maintains continuous contact with the serrated outer surface 24 of the shaft 22. Such a structural configuration provides the unexpected and unpredictable advantage of ensuring each of the grabbing members 28 pivotally articulates in sync without becoming undesirably separated from body 11 and/or shaft 22.

(26) In a non-limiting exemplary embodiment, the grabbing members 28 are contemporaneously pivoted in sync about pivot pins 32 and along mutually exclusive arcuate travel paths 33, respectively. It is noted that each arcuate travel path 33 is associated with a corresponding one of the drive gears 30. Although, all three arcuate paths 33 are not illustrated, one skilled in the art understands each arcuate travel path 33 is unique and non-overlapping with an adjacent drive gear 30. Such a structural configuration provides the unexpected and unpredictable advantage of applying a uniform initial torque or initial frictional force to pivotally deploy each grabbing member 28 equidistantly away from body 11 and shaft 22.

(27) In a non-limiting exemplary embodiment, referring to FIGS. 1, 3-6a, each of the grabbing members 28 are registered substantially parallel to the centrally registered longitudinal axis 13 when the actuator 21 is at a released equilibrium position 19 (fully exposed from cavity 12) and the shaft 22 is at a retracted equilibrium position. Such a structural configuration provides the unexpected and unpredictable advantage of ensuring each grabbing member 28 is retracted in sync and returns to an original resting (equilibrium) position when not deployed.

(28) In a non-limiting exemplary embodiment, referring to FIGS. 7-9a, each of the grabbing members 28 are angularly registered relative to the centrally registered longitudinal axis 13 when the actuator 21 is at a depressed tensioned position (pushed into cavity 12) and the distal end 15 of the shaft 22 is displaced outwardly away from the distal end 15 of the body 11. Such a structural configuration provides the unexpected and unpredictable advantage of enabling a user to grab around the target object and maintain sufficient surface area contact therewith during the object retrieval process. This can be especially useful when retrieving annular or spherical objects from space-confined areas.

(29) In a non-limiting exemplary embodiment, each of the grabbing members 28 further includes a substantially triangular-shaped wedge 35 coupled to the interior surface 29 of the grabbing members 28 and radially extended towards the centrally registered longitudinal axis 13. Such a structural configuration provides the unexpected and unpredictable advantage of ensuring each grabbing member 28 returns to its original resting position (equidistantly offset from centrally registered axis 13).

(30) In a non-limiting exemplary embodiment, each of the triangular-shaped wedges 35 has a lateral side 36 respectively conjoined and spaced apart from an adjacent one of the triangular-shaped wedges 35 when the grabbing members 28 are at the retracted equilibrium position 19 (FIGS. 1, 3-6a) and the expanded tensioned position 20 (FIGS. 7-9a), respectively. Such wedges 35 provide the unexpected and unpredictable advantage of ensuring the grabbing members 28 return to an equidistantly offset orientation substantially parallel to the centrally registered longitudinal axis 13. Such a structural configuration provides the unexpected and unpredictable advantage of preventing the grabbing members 28 from pivoting inwardly beyond their original resting position and maintains the equidistantly spaced configuration of the object-grabbing section 18.

(31) The present disclosure further includes a method of utilizing a multi-functional walking cane 10 for assisting a user to reach and pick up objects that may be too high or on the floor. Such a method includes the chronological steps of: providing a body 11 including a cavity 12 having a centrally registered longitudinal axis 13, a proximal end 14 and a distal end 15 opposed therefrom, and a handle 16 disposed at the proximal end 14; providing an object-grabbing mechanism 17 having an object-grabbing section 18 seated exterior of the body 11; operably communicating the object-grabbing mechanism 17 with the body 11; and resiliently deploying the object-grabbing section 18 between a retracted equilibrium position 19 and an expanded tensioned position 20, respectively.

(32) A non-limiting exemplary embodiment(s) of the present disclosure is referred to generally in FIGS. 1-9a and is intended to provide a multi-functional walking cane 10 featuring an object-grabbing mechanism 17 incorporated into the bottom thereof for assisting a user to reach and pick up items that may be too high or on the floor. It should be understood that the exemplary embodiment(s) may be used to pick up a variety of items, and should not be limited to any particular item described herein.

(33) Referring to FIGS. 1-9a in general, in a non-limiting exemplary embodiment(s), a specially designed walking cane 10 has an object-grabbing mechanism 17 incorporated into the bottom of the unit. The multi-functional walking cane 10 may feature an attractive weather-resistant aluminum or wood outer casing, and feature the tubular, elongated design of these devices. Optionally measuring approximately 34 inches in length and of an inch in diameter, the multi-functional walking cane 10 may feature a hook-like hand-grip (handle 16) at the proximal end 14 of the body 11 designed expressly to facilitate a firm and comfortable hold during use. Partially located within the interior of the body 11 is object-grabbing mechanism 17. A non-skid fitted cap 44 can be secured over the distal end of object-grabbing mechanism 17 and removed prior to activating the object-grabbing mechanism 17.

(34) A jaw-like object-grabbing section 18 preferably culminates in a series of three or four hinge-mounted prongs (e.g., grabbing members 28). Designed to expand (articulate) outwardly in a wide arc, and inwardly to a resting position, the object-grabbing section 18 is operated by a push button trigger (e.g., actuator 21), located adjacent to the handle 16. The object-grabbing section 18 is mounted to an extendable shaft 22 that emerges from the distal end 15 of the cane 10 on demand (e.g., user input), via the actuator 21. As such, the multi-functional walking cane 10 is utilized as a fully functioning walking cane 10, providing sturdy and reliable support to the user. In the event one needs to fetch an item out of reach or on the ground, he/she simply removes the end cap 44 from the distal end 15 of the cane 10. The user then need only press the trigger (actuator 21) to release/deploy the prongs (grabbing members 28), and place the object-grabbing section 18 over the target object. Releasing the actuator 21, the user is able to pinch closed (e.g., retract) the grabbing members 28 onto the target object, and simply bring it closer to the user for easy retrieval.

(35) There are several significant benefits and advantages associated with this clever product invention. For example, the multi-functional walking cane 10 is safer and provides a more effective apparatus to retrieve objects that are out of reach. Offering the object-grabbing mechanism 17, which allows the user to remain upright at all times, this practical cane 10 alleviates the possibility that one may slip and fall when bending down or reaching upward for an elusive item. In this manner, users who depend on canes 10 to assist in walking will not have to worry about breaking bones or suffering serious injuries.

(36) Weather-resistant, the multi-functional walking cane 10 is appropriate for either indoor or outdoor usage. Universal in construction, this versatile cane 10 is invaluable to those who need canes 10 to assist in their mobility. Ideal for use by children as well as adults, the easy to use multi-functional walking cane 10 is configured to be opened, gripped around a target object, and used to bring the object in easy reach, all in a matter of seconds.

(37) While non-limiting exemplary embodiment(s) has/have been described with respect to certain specific embodiment(s), it will be appreciated that many modifications and changes may be made by those of ordinary skill in the relevant art(s) without departing from the true spirit and scope of the present disclosure. It is intended, therefore, by the appended claims to cover all such modifications and changes that fall within the true spirit and scope of the present disclosure. In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the non-limiting exemplary embodiment(s) may include variations in size, materials, shape, form, function and manner of operation.
