Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION Field of the Invention The present invention relates to a portable telescopic device which is used by elderly people who have difficulty walking or who have low physical strength and which is used during walking. 2. Description of the Related Art When a walking person has difficulty walking, an elderly person or a person with weak physical strength can use a walking stick to support the body, and walking is convenient without fatigue. In a general cane, one long rod is bent at one end, and the bent portion is used as a grip for grasping with a hand. In addition, there is a cane that does not get in the way because the staff is long when the staff does not use it when going out. This type of cane can be screwed or fitted at the point where two or three short rods join each other, so it can be used as a single wand or removed whenever it is in the way. It can be shortened. When going out, it is convenient to use a walking stick while walking, but it can be a hindrance when sitting in a chair or holding a long walking stick where people are crowded. In addition, there is a drawback in that it is cumbersome and troublesome to attach the cane when lengthening it or to remove it when shortening it. The purpose of the present invention is to make it possible to use a cane as a long cane, and to operate it easily when not using it or carrying it. ,
Another object of the present invention is to make a long wand be instantly fixed by each engaging element urged by a spring member by simply pulling both ends of the reduced wand by hand to the left and right. Means for Solving the Problems In order to achieve the object, the present invention forms a pair of small-diameter pipes and a bent handle at the upper end of the small-diameter pipe so that the small-diameter pipe can slide. A medium-diameter pipe which is inserted and forms a notched inclined surface at a lower portion, a large-diameter pipe slidably inserted into the medium-diameter pipe, and a first small hole formed at a lower end of the small-diameter pipe; A first engaging element which engages with and disengages from a second small hole formed at the upper end of the medium diameter pipe; a third small hole formed at the lower end of the medium diameter pipe; A second joint engaging and disengaging the four small holes, a first spring member and a second spring which constantly bias the first and second flanges formed on the first and second engagement members in an outward direction; A finger member fixed to one end of a release operation rod inserted into the small-diameter pipe and exposed to the outside through a notch hole in the grip portion; A release member fixed to the other end of the release operation rod, having a cutout portion, and forming a smooth surface from the inclined surface at the tip, and a spring for constantly biasing a finger holding member connected to the release member by the release operation rod Components,
A non-slip member formed at the lower end of the large-diameter pipe is provided, and when operated against a spring member that constantly urges the finger holding member, the inclined surface at the distal end of the release member contacts the first flange portion while being in contact with the first flange portion. (1) The engaging member is retracted, the small-diameter pipe is slidably fitted into the medium-diameter pipe, and the second engaging member is retracted while the inclined surface cut out at the lower portion of the medium-diameter pipe contacts the second flange portion. Then, the medium diameter pipe and the small diameter pipe reduced to the large diameter pipe can be accommodated by slidably fitting the medium diameter pipe into the large diameter pipe. When the operating finger contact member is operated against a spring member that constantly urges, the inclined surface at the distal end of the release member retreats the first engaging element while abutting on the first flange, and the medium diameter pipe is inserted into the large diameter pipe. The pipe is slidably fitted, and the second engaging element is retracted while the notched inclined surface at the lower portion of the medium diameter pipe abuts on the second flange so that the small diameter pipe can slide on the medium diameter pipe. By fitting the medium pipe, the medium-diameter pipe and the small-diameter pipe reduced to the large-diameter pipe can be stored.
