Abstract
Description
- The invention relates to the field of combination canes and extended grabbing devices for aiding individuals in walking and in assisting a user to grasp objects out of the user's normal reach.
- As the ranks of the elderly increase with the advancing age of the baby boomers, there exists a wide variety of medical and physical infirmities that can afflict this population. Among one of the more common ailments are those affecting the knees, hips and back that limit the ability of the individual to walk without aid or to bend over to pick up an object lying on the ground. Other groups of individuals with walking difficulties can include those injured by an accident or other medical conditions that make it difficult for them to walk without the aid of a cane of some other type of support. Therefore, a number of prior art canes have been described to provide an individual with a cane and/or a cane that also includes an apparatus, forming a permanent part of the cane, for grasping objects at a distance from the user.
- For example,
U.S. Pat. Nos. 5,392,800 ,5,636,650 and5,640,985 all describe hollow canes in which tension applied to a cable extending within the hollow cane body causes a grasping arm pivotally mounted near the lower rubber tip of the cane to pivot inward, closing a gap against the rubber tip in order to grasp an object. - Other patents describe a mechanism extending external to the body of the cane for moving a pivotally mounted grasping arm.
U.S. Pat. No. 5,176,160 discloses a grasping arm that is pulled into contact with the rubber cane tip by means of a cable extending along the outside of the cane, with the cable being pulled by pivoting a lever near the cane handle. -
U.S. Pat. No 6,527,321 to Kuciauskas discloses a grabber and a combined cane and grabber. In the combined cane and grabber, the cane is made of two pieces such that in one alignment the apparatus acts as a standard cane with a "T" handle. By lifting the apparatus off of the ground and pivoting the two cane halves 360 degrees relative to each other, the apparatus acts as a grabber by utilizing the "T" handle ends as ears and lugs for grabbing objects off of the ground. -
U.S. Pat. No. 5,692533 discloses a walking cane with a larger foot member that includes a plurality of forward and downward integrally dependant legs which rigidly extent from the lower member of the support member. This provides additional support and stability to the base of the cane for elderly and infirm individuals to aid in walking. - All of the patents described above require structural differences between the cane being described and a conventional cane to an extent that a conventional cane cannot be readily modified to perform in accordance with the described invention. What is needed is, however, is a cost effective means to provide those requiring assistance in walking with a walking cane that can be easily converted into a grasping device to allow them to securely grasp and safely hold objects that are out of their normal reach. A further object of this invention is to provide a combination walking cane and grasping device with a means for easily converting the walking cane tip into a broader base for those requiring additional stability when walking.
- None of these, or other references known to the inventor, treat the problem addressed by the invention, that is, provide a safe, stable and secure walking cane which provides rigid stationary support, while allowing easy use of the device as a grasping tool.
- According to an aspect of the present invention, there is provided a cane and grasping device as specified in
claim 1. According to another aspect of the present invention, there is provided a method for using a walking cane as specified inclaim 11. According to a further aspect of the present invention there is provided a walking cane device as specified inclaim 16. - The instant invention relates to a walking cane that includes a means for easily converting the cane into a tool for grasping items out of the normal reach of an individual. The cane comprises two substantially vertical members, pivotably connected to each other, each vertical member having an upper end, a lower end and a longitudinal axis thereof. The upper end being the handle end and the lower end being the tip end. Upon releasing a first locking mechanism, the handle end can be opened up, thereby opening up the tip end to provide a gripper end for grasping objects distant from the handle end. The gripper end being shaped to provide a flat gripper for grasping objects as well as a concave surface for gripping cylindrical objects. Upon closing the apparatus and securing the first locking mechanism the two vertical members interlock to prevent the members from separation during use as a cane.
- In an additional embodiment, when used as a cane, the tip can be securely placed and held into a separate base that comprises a broader base surface for additional support and stability. To release the cane in order to utilize the gripping features, the user simply presses a foot lever on the base to release the cane from the separate base. The cane can then be opened up to use as a gripper by releasing the first locking mechanism in the cane and gripper device. When the user desires to re-attach the separate base to the cane, they simply close the cane together and push the tip of the cane into the opening of the separate base which secures the cane to the separate base with a second locking mechanism.
- Other advantages, features and benefits of the invention will become apparent to those skilled in the art upon reading the detailed description taken in conjunction with the drawings, which are meant to be only exemplary of the invention and not meant to limit the invention as defined by the appended claims.

curved portion 40 on thecane tip 4 is replaced with a separate non-skid material (not shown) for the internal curved portion and a separate replaceable non-skid material cup portion (not shown) that fits over the end tip for traction with the ground when the device is utilized as a cane. This allows for replacement of the non-skid cup tip portion if it is damaged or wears out through use of the cane. - In an additional embodiment, shown in
Figs. 11 and12 , the cane tip andgripper section 4 can be removably inserted into abroader base 45. Theremovable base 45 can be molded out of plastic, resin or other such materials and have two or more feet 47 (only two are shown). Each of thefeet 47 can havetips 48 for providing additional traction, such as those made out of rubber or the like. Thus, when the cane tip andgripper section 4 is placed into thebase 45, thebottom tip 49 of the cane tip andgripper section 4 is planar with thetips 48 on thelegs 47 thereby providing a stable base for the walking cane andgripper 1. -
Fig.12 depicts a cross-sectional view of thebroader base 45 with the cane tip andgripper section 4 inserted into thebase 45. Theinner surface 51 of thebase 45 is formed to match the form of the cane tip andgripper end 4. On each side of the cane tip halves 36 and 37, there is ablind hole 44. Mounted into the base 45 are twopins 50 located inline with theholes 44. The tip end of thepins 50 being tapered to allow for easy insertion of the cane tip andgripper section 4. Thepins 50 move slideably inholes 52 formed into thebase 45. In each of theholes 52 there is acompression spring 53 that biases thepins 50 outwardly. Thus, when the cane tip andgripper 4 is inserted into thebase 45, thepins 50 move backwards into theholes 52 as the cane tip is being inserted and then forward into thehole 44 in the cane tip andgripper section 4 when theholes 44 in the cane tip align with thepins 50 thereby locking the base 45 securely to the cane tip andgripper section 4. - To release the walking cane and
gripper 1 from thebroader base 45, the user depresses thespring 54 loadedbutton 55 which in turn pushes down on acable 56. Thecable 56 is connected around pulleys 57 to the base of eachpin 50. By depressing thebutton 55, thecable 56 moves downward, thereby causing thepins 50 to be pulled back into theholes 52 in thebase 45, which in turn releases the walking cane andgrabber 1 from thebase 45. Other means of securing and releasing the walking cane andgripper 1 to the base 45 can be easily derived from the concepts presented here by those skilled in the art. - Thus it is apparent that there has been provided, in accordance with the invention, a cane and grabber that satisfies the aims and advantages set forth above. While the invention has been described in conjunction with the specific embodiments thereof, it is evident that there may be many alternatives, modifications and variations that may be apparent to one skilled in the art of the foregoing description. Accordingly, it is intended to embrace all such modifications and alternatives as may fall within the scope and spirit of the appended claims.
