Description

BACKGROUND OF THE INVENTION

This invention relates generally to walking sticks and more specifically to a multifunctional walking stick and method of use.

Demand for movement assistive devices such as walking sticks and the like is expected to increase commensurate with current increase in elderly population. Many such elderly users employ walking sticks for stability when they walk or when they exercise. Walking sticks are also used by healthy lifestyle individuals for lifestyle activities such as hiking and the like.

Briefly, walking sticks typically include an elongated 3 ft-5 t shaft (or stem) having an attached handle and an affixed rubber base. A user can employ this walking stick by gripping the attached handle and placing the affixed attached base on the ground. The walking stick is placed adjacent to the user for support as the user proceeds. This process continues and is repeated until the walking activity is concluded.

Elderly users usually exercise by engaging in daily and nightly walks. Assume that during one such activity, an elderly user with a conventional walking stick is approached by a barking dog. Instinctively, the user attempts to protect against the barking dog by prodding or swinging the walking stick. This results in loss of balance causing the user to fall. Unfortunately, not only does the user now incur injuries from falling, the user also sustains dog bites inflicted by the barking dog. The same can also be said when users are approached by assailants. They may sustain injury from falling and/or from such assailants.

Assume that this elderly user is a healthy lifestyle individual. Also assume that this individual now wishes to engage in a hiking activity. This user then begins by switching from the walking stick to a purposefully designed hiking stick since walking sticks are not designed for hiking. After hiking for several hours and over fairly difficult terrain, the user is now fatigued and/or lost. The user is unable solve this problem without proper equipment separate and apart from the hiking stick.

There is a need to address one or more of the foregoing disadvantages associated with conventional walking sticks and the present invention meets this need.

BRIEF SUMMARY OF THE INVENTION

Various exemplary embodiments can be found in a walking stick of the present invention. In one embodiment, a dog deterrent walking stick is disclosed. This walking stick includes an elongated stem (shaft) with an attached handle and an attached base. Unlike conventional systems, the dog deterrent walking stick of the present invention includes an ultrasonic device incorporated into the elongated stem. In one aspect, the ultrasonic device is incorporated by mounting the device within the elongated stem with an activation button positioned fairly close to the user's hands. In another aspect, it is incorporated by detachably fixing it to the exterior of the elongated stem.

The ultrasonic device can issue inaudible ultrasonic sound with at least a 20 KHz frequency. This causes approaching or barking dogs to stay in place, stop or move away from the user. Unlike conventional systems, elderly users need not carry a separate ultrasonic device as it is incorporated with the walking stick. They need not use this walking stick for prodding or swinging at approaching dogs thus jeopardizing their stability. They can simply activate the ultrasonic device while maintaining their stability. Ultrasonic sound, moreover, presents a more humane dog deterrent unlike conventional walking stick pepper spray cans that can injure animals.

A further embodiment of the present invention discloses a multifunctional walking stick. This multifunctional walking stick includes an elongated stem having an attached handle and an attached interchangeable base. Unlike conventional walking sticks, the interchangeable base of the present invention has a selectable base bottom. The base bottom might be selected from a walking (quad-pod) base bottom, a hiking base bottom, an ice traversing base bottom and a claw base bottom, for example. Thus, healthy lifestyle individuals can use this multifunctional walking stick for both walking and hiking, for example, by switching between the walking base bottom and the hiking base bottom. With the present invention, users need not maintain multiple sticks for different activities. A portion of the elongated stem is also telescopic for adjusting the walking stick height.

The multifunctional walking stick of the present invention further includes a detachable modular safety device. This safety device is attached by clamping a safety device casing around the elongated stem exterior so that the modular safety device can be inserted and removed (by latch release) from the safety device casing.

The detachable modular safety device includes a power supply, a dog deterrent device, an audible alarm device and a location tracer device. The modular safety device may also include a navigational compass, a flare compartment for storing flares and glow sticks and a fluorescent strip that is highly visible from distances of between and 10 ft-50 ft away. Users are therefore provided with highly desired safety devices or measures incorporated into the multifunctional walking stick of the present invention, and they can easily access these devices in the event they are lost, fatigued, attacked by assailants or when they need help.

An understanding of the nature and advantages of the present invention herein may be realized by reference to the remaining portions of the specification and the attached drawings. Further features and advantages of the present invention, as well as the structure and operation of various embodiments of the present invention, are described in detail below with respect to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the preferred embodiments, it will be understood that they are not intended to limit the invention to these embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be obvious to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the present invention.

FIG. 1 illustrates walking stick 100 in accordance with an exemplary embodiment of the present invention.

Walking stick 100 broadly consists of three main components namely handle 102, stem 104 and base 106. Stem 104 is an elongated substantially square-shaped shaft connecting handle 102 and base 106. Although not shown, these components can be connected directly or indirectly by known methods such as screwing, riveting, forging, etc.

In use, briefly, walking 100 may be employed for walking, hiking, etc. A user begins by adjusting the walking stick height. This is done by manipulating telescopic stem 118 until a comfortable height is attained. Once a desired height is obtained, the user can then use walking stick 100 by grasping handle 102 at waist high level while placing base 106 on the ground. Walking stick 100 is then leaned upon to provide partial support as the user takes another step forward. This process continues and is repeated until the walking activity is concluded.

The user can also depress as necessary one or more safety buttons attached to stem 104. For example, dog deterrent button 12a can deter approaching barking dogs or the like from the user. Unlike conventional devices, the walking stick of the present invention incorporates a dog deterrent device providing users with much needed comfort and protection from aggressive type animals. Other safety buttons described with reference to FIG. 3 can also be depressed in an alternative embodiment of the present invention.

In FIG. 1, in more detail, handle 102 is ergonomically designed to maximize productivity by reducing user fatigue and discomfort. The embodiment of FIG. 1 shows affixed handle 102 having upper grip 108 and lower grip 110. Upper grip 108 and lower grip 110 are continuous extensions of stem 104, over which grip material such as polyurethane, plastic, fiber resin and the like is molded to form the grips. Alternately, upper grip 108 and lower grip 110 can be separately formed or molded. The separately formed handle can then be fixedly attached to stem 104 using screws, riveting or the like.

The embodiment of FIG. 1 also illustrates a non-curved handle 102. Here, the longitudinal axis of upper grip 108 is substantially perpendicular to that of lower grip 110. Some users may prefer this substantially non-curved handle 102 to other handle types. For increased comfort, grips 108 and 110 can be made of soft comfortable material such as foam and the like. Preferably, the foam is substantianly square shaped to conform to the shape of stem 104, and can also have indentations for comfortable gripping. The foam interior is dimensioned so it is slideable over stem 104. Preferably the lengths of upper grip 108 and lower grip 110 are 5″ and 5″, respectively. The grip sizes can be at least three standand sizes namely small, medium and large.

FIG. 1A illustrates handle 102 according to an exemplary embodiment of the present invention.

In FIG. 1A, the user can adjust handle 102 between position A and position B, as shown. In position A, the longitudinal axis of upper grip 108 is substantially perpendicular to that of lower grip 110. This position is preferable for some users particularly when they are engaging in walking activities as they can easily grasp upper grip 108. In position B, upper grip 108 is substantially continuous with lower grip 110, with a single longitudinal axis running through both upper grip 108 and lower grip 110. This position is preferable for other users particularly when they are engaging in activities such as hiking and the like.

The user can depress handle button 111 to adjust handle 102 between position A and position B. This allows a lock mechanism (not shown) to release upper grip 108 from its current fixed position. Once the desired position is selected, upper grip 108 is again locked into position by depressing handle button 111. Upper grip 108 and lower grip 110 are coupled by hinge mechanism 109 such that upper grip 108 is rotatable around the hinge mechanism 109 axis.

FIG. 1B illustrates handle 102 according to another exemplary embodiment of the present invention.

In FIG. 1B, handle 102 is curved as shown, for users preferring curved handles rather than. Specifically, upper grip 108 of handle 102 possesses a semi-circular axis or curvature. Lower grip 110 of handle 102 is also substantially rounded in this case. In fact, walking stick 100 has a substantially rounded and circular stem 104 from which lower grip 110 is continuously formed. Handle 102 includes three different handle choices namely sport, hiking and walking.

Referring back to FIG. 1, stem 104 also includes dog deterrent system 112 that can emit high pitched ultra-frequency sounds to force aggressive animals (particularly barking dogs and the like) to keep their distance from the user. Dog deterrent system 112 is fixedly incorporated within stem 104 preferably immediately below handle 102 so that proximity to the user's hands is maintained. Alternately (not shown), dog deterrent system 112 may be located within upper grip 108 so that its button is easily manipulable by the user's thumb.

Dog deterrent system 112 includes button 112a with metal contact 112b. Button 112a is spring loaded (not shown). Depressing button 112a causes metal contact 112b to close switch 112c thus completing and activating this dog deterrent system circuitry. Switch 112c is coupled to ultrasonic device 112d, which is fixedly mounted to the interior wall of stem 104. Ultrasonic device 112d is dimensioned to fit within stem 104, which itself has exterior dimensions of up to 3.5″ by 3.5″ (or up to 3.5″ diameter when the stem is substantially rounded).

Dog deterrent system 112 also includes power supply 112e for supplying power to ultrasonic device 112d. Power supply 112e comprises batteries located also within interior of stem 104 and opposite ultrasonic device 112d. A slideable door (not shown) is also provided so batteries can be replaced. Power supply 112e is communicably coupled to ultrasonic device 112d via wires 112f.

The high pitched ultra-frequency sounds that can be emitted by depressing button 112a have frequencies above 20 kHz that are inaudible to human ears. Preferably, the emitted sound is most effective when the canine is 15 ft or closer but is also operative up to 75 ft away. The ultrasonic output startles the approaching dog and causes most dogs to stop, move away or stay in place. An advantage of ultrasonic sound is that it is not physically harmful to canines and is a humane substitute for other deterrent types like pepper spray. It is also advantageous because ultrasonic sound is inaudible to human ears thus avoiding public disturbance that can be created by loud audible beeper or horn type devices.

Stem 104 further includes telescopic stem 118, which consists of external stem 120 and internal stem 122. The user can adjust the height of walking stick 100 by adjusting telescopic stem 118. As shown, internal stem 122 is slideable into external stem 120. Spring loaded pins (not shown) attached to the exterior wall of internal stem 122 can lock into apertures or security notches (not shown) cut out in external stem 120. The user can adjust to a desired height by depressing a spring loaded pin to release exterior stem 120, and pulling exterior stem 120 and interior stem 120 in opposite directions so stem 104 is extended to the desired length; a spring loaded pin then clicks into a desired exterior stem 120 aperture to lock stem 104 in place.

Stem 104 is preferably made of sturdy light weight material such as aluminum or comparable alloys although other materials consistent with the present invention can be employed. For example, plastic, polyurethane or fiber resin may be used. Stem 104 including its telescopic stems can resist breakage pressure of up to 500 lbs. Preferably, stem 104 weighs such that that walking stick 100 weighs no more than 2.5 bs. Stem 104 height can range from 2′-5′ and its diameter can be up to 3.5″. Stem 104 is also waterproof and ice-proof capable of withstanding extreme cold and heat. The walking stick of the present invention itself, tentatively dubbed Prostick™ can come in various color choices with a futuristic and modern/spacey look.

As shown in FIG. 1, walking stick 100 also includes base 106, consisting of collar 124 and walking base bottom 126. Collar 124 is a raised horizontal molding encircling stem 104. Preferably, its interior is treaded to receive exterior threads of walking base bottom 126. Preferably, walking base bottom 126 can be rubber or other elastomeric material. In an alternate embodiment, walking base bottom 126 is selectable from various available base bottoms.

FIG. 2 illustrates walking stick 200 according to another exemplary embodiment of the present invention.

In FIG. 2, walking stick 200 permits the user to detach dog deterrent system 212. This dog deterrent system emits inaudible ultrasonic sound when button 218 is depressed. Upon detachment, the user can utilize ultrasonic device 216 independent of walking stick 200. Unlike the embodiment of FIG. 1, dog deterrent system 212 can be conveniently detached since it is modular with its own power supply 218. As shown, dog deterrent system 212 is removably coupled to walking stick 200 by clamping mechanism 222 having strap 226 and jacket 224.

The user can detach ultrasonic device 216 by opening cover 214, unlatching the device and then removing ultrasonic device 216 in the direction shown. After the device is detached, an empty jacket 224 remains. The user can also reinsert ultrasonic device 216 by reversing the insert process. Cover 214 is first opened. Next, ultrasonic device 224 is inserted into jacket 224. Upon being inserted, ultrasonic device 216 is locked in place and can then be activated by using button 218. Therefore, unlike conventional systems, the present embodiment allows ultrasonic device 216 to be employed with or without walking stick 200.

FIG. 3 illustrates walking stick 300 according to another exemplary embodiment of the present invention.

In this embodiment, not only can walking stick 300 generate audible alarms that force dangerous assailants to flee from the user, it can also include real time tracking to determine the user's location. As in prior embodiments, walking stick 300 also includes a dog deterrent device. Unlike conventional devices, the present invention incorporates all of these features into a modular safety device 303 detachably enclosed within exterior casing 325. This allows the user to detach and employ safety device 303 independent of walking stick 300. Safety device 300 has exterior dimensions preferably up to 3″ by 3″ by 1″ and weighs no more than 2.5 lbs.

In FIG. 3, exterior casing 325 is detachably coupled to elongated stem 304 with clamp bracket 307. Exterior casing 325 encloses safety device 303 and incorporates deterrent button 309, panic button 311 and tracer button 313 as shown.

In FIG. 3, dog deterrent device 312 functions in a similar manner as described with reference to prior embodiments. Panic device 313 can issue an audible alarm preferably between 90-120 dB. This is effective for use against dangerous animals such as bears and mountain lions and dangerous assailants. Preferably, the audible alarm is continuous for three to five minutes with one to two second intervals. It is deactivated by depressing panic button 311 for a second time.

Tracer device 315 is a real time tracking device for determining the user's location. This can be helpful, for example, during hiking when the user is lost. As with other features of the present invention, users need not carry separate tracking devices on their person. The real time tracking device of the present invention is integral with safety device 303 and is capable of receiving signals from GPS (Global Positioning System) satellites to accurately determine the user's location. Location data can be transmitted either automatically or on demand for viewing over maps or via text reports to email, mobile phone or the like. Although not shown, another navigational tool that is included in safety device 303 is a digital compass for use as a navigational tool during travel and a digital walking monitor for indicating time and monitoring distance (or steps) traveled during a given activity.

In FIG. 3, walking stick 300 further includes removable flare/glow stick compartment 327 for storing flares and glow sticks. This compartment may have an apperture and door (not shown) through which such flares and glow sticks are retrieved. Preferably, 2-6 inch sized glow sticks and/or flares are storable in compartment 327. When lost, for example, the user can utilize these flares/glow stick for distress signaling. Flares storable in compartment 327 are readily available from Orion® Safety Products, Easton Md.

Although not shown, walking stick 300 includes a fluorescent strip mounted on stem 304. Its visibility promotes safety for walking stick users. This fluorescent strip is observable from distances of between and 10 ft-50 ft away. In this manner, users and their walking sticks remain highly visible (both during the day and at nighttime). This can avoid motor vehicle injury to walking stick users, for example. Preferably, the strip is approximately 1 inch wide and runs the entire length of stem 104.

Walking stick 300 further comprises telescopic stem 318 having external stem 320, internal stem 322 and inner stem 324.
