Abstract
A cane is disclosed that includes a handle having a lower protrusion; a shaft having a top projection matingly secured to a bottom recess of the protrusion; and a sleeve adapted to securely put on the protrusion, an upper portion of the shaft, or a joining portion of the protrusion and the upper portion of the shaft. The invention can increase structural strength of the cane.
Description
- 1. Field of Invention
- The invention relates to devices for aiding a user to walk, and more particularly to a cane with enhanced structural strength by providing a sleeve securely put on a joining portion of a bottom of the handle and a mating top of the shaft.
- 2. Description of Related Art
- Cane devices are particularly useful for, for example the elderly or mountain climbing, as means for aiding in walking. Typically, most weight of the user is borne upon the cane while walking.
- Conventionally, a cane comprises a horizontal handle and an elongate shaft. It is typical for the handle and the shaft to be manufactured separately prior to assembling together for the purpose of simplifying the manufacturing process.
- A longitudinal sectional view of a conventional cane is shown in
FIG. 1 . The cane is shaped as a “T” and comprises a handle A having a recess C on its bottom, and an elongate shaft B having a projection D on its top. The projection D is dimensioned and shaped to insert into the recess C prior to being secured together by, for example, gluing. - However, the well known cane suffers from a disadvantage. For example, its structural strength is weak in view of the fact that the fastening at the joining point of the projection D and the recess C is prone to breaking due to external force exertion.
- There have been numerous suggestions in prior patents for canes. For example, U.S. Pat. No. 6,341,614 discloses a collapsible cane. Thus, continuing improvements in the exploitation of cane are constantly being sought.
- It is therefore one object of the invention to provide a cane with enhanced structural strength by providing a sleeve securely put on a joining portion of a bottom of the handle and a mating top of the shaft.
- In one aspect of the invention the sleeve is adapted to conceal the joining portion so as to prevent same from deforming or damaging due to external force exertion, thereby protecting the cane.
- In another aspect of the invention the sleeve is made of metal or plastic and is aesthetic.
- The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
-
FIG. 1 is a longitudinal sectional view of a conventional cane; -
FIG. 2 is a perspective view of a first preferred embodiment of cane according to the invention; -
FIG. 3 is an exploded view of the joining portion of the handle and the shaft ofFIG. 2 ; -
FIG. 4 is a longitudinal sectional view of the joining portion ofFIG. 3 ; -
FIG. 5 is a longitudinal sectional view of the assembled joining portion ofFIG. 4 ; -
FIG. 6 is a longitudinal sectional view of an assembled joining portion of handle and shaft of a second preferred embodiment of cane according to the invention; and -
FIG. 7 is a longitudinal sectional view of an assembled joining portion of handle and shaft of a third preferred embodiment of cane according to the invention. - Referring to
FIGS. 2 to 5 , a cane in accordance with a first preferred embodiment of the invention is shown. The T-shaped cane comprises ahandle 10, ashaft 20, and asleeve 30 securely put on a joining portion of a bottom of thehandle 10 and a mating top of theshaft 20. Each component is discussed in detail below. - The
handle 10 comprises agrasping portion 11 and abottom protrusion 12. - The
handle 10 can be shaped other than shown. For example, thehandle 10 can be shaped as a hook or a cylinder depending on applications. - The
shaft 20 is elongate and has a sufficient length so as to aid a user to walk. Theshaft 20 can have a fixed length or can be made as collapsible (i.e., telescopic). - The
sleeve 30 is a hollow cylindrical member and is adapted to put on a joining portion of theprotrusion 12 and a mating top of theshaft 20 as detailed later. - Referring to
FIGS. 3 , 4 and 5 specifically, a coupling of theprotrusion 12, theshaft 20, and thesleeve 30 is shown in which, as an exemplary example, theprotrusion 12 comprises abottom recess 121, theshaft 20 comprises anupper portion 202 of reduced diameter and aprojection 201 on a top of theupper portion 202, thesleeve 30 is dimensioned and shaped to fit snugly onto theupper portion 202, and theprojection 201 is dimensioned and shaped to insert into therecess 121 prior to being secured together by, for example, gluing. - Note that the
upper portion 202 and thus theshaft 20 are protected by tightly putting thesleeve 30 on theupper portion 202. - Referring to
FIG. 6 , a cane in accordance with a second preferred embodiment of the invention is shown. The characteristics of the second preferred embodiment are detailed below. Thesleeve 30 has an upper extension which is adapted to fit onto a lower portion of theprotrusion 12 of reduced diameter so that a joining portion of theprotrusion 12 and the upper portion 22 is protected. The second preferred embodiment aims at further preventing the joining portion of the protrusion 12 (i.e., the handle 10) and the upper portion 22 (i.e., the shaft 20) from deforming or damaging due to external force exertion. - Referring to
FIG. 7 , a cane in accordance with a third preferred embodiment of the invention is shown. The characteristics of the third preferred embodiment are detailed below. The lower portion of theprotrusion 12 is provided without a reduced diameter and theshaft 20 is provided without the upper portion of reduced diameter. That is, theprotrusion 12 has a diameter the same as that of theshaft 20. Also, thesleeve 30 is adapted to fit onto a lower portion of theprotrusion 12 and an upper portion of theshaft 20 for fastening. - In one configuration of the third preferred embodiment the
sleeve 30 is adapted to put on only the upper portion of theshaft 20. In the other configuration of the third preferred embodiment thesleeve 30 is adapted to put on only the lower portion of theprotrusion 12. - Preferably, the
sleeve 30 is made of metal or plastic and is aesthetic. - While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
