Abstract

(57) [Summary] [Objective] The object of the present invention is to improve a known length-adjustable cane to provide a cane that can easily adjust the length and fix the same. is there. [Structure] A grip that is fixed to the upper end of the large-diameter upper stage shaft, and a stone thrust is provided at the lower end of the lower shaft lower shaft. A plurality of through holes are formed along the longitudinal direction of the shaft to fix each stage shaft after adjusting the length, and the pin urged by a spring provided in the shaft is provided. In the cane fitted and engaged with the through hole, one surface along the longitudinal direction of the peripheral surface of each shaft constituting the cane whose length can be adjusted is formed as a flat surface, and in the longitudinal direction of this flat portion. A cane comprising a plurality of through holes for fixing after adjusting the length.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a cane whose known length is adjustable and which can be easily adjusted and fixed.

[0002]

[Prior art]

 A cane or rod having at least two expandable and contractible shafts whose length can be freely adjusted is not only known as a camera tripod or the like, but also a ski pole as disclosed in Japanese Utility Model Publication No. 32-13181. There are a rod-shaped body of Japanese Utility Model 4-18413 and a pickle of Japanese Utility Model Laid-Open No. 5-29683. However, when these conventional technologies are used for walking canes, when adjusting and fixing the length, it is not easy to fit the pin into the hole and the shaft is rotated many times. It is.

[0003]

[Problems to be solved by the invention]

 It comprises a telescopic tube which can be extended and contracted, and after adjusting the length, a plurality of through-holes are drilled along the longitudinal direction to fix each shaft, and the pin urged by a spring provided in the shaft is used as described above. It is a modification of the well-known technique of engaging the through hole, and when adjusting the length of the shaft, pulling the shaft upward or downward without pulling the shaft up and down repeatedly without rotating the shaft many times causes the pin to move into the through hole. It is an object of the present invention to provide a cane that can be fitted and engaged with a wand.

[0004]

[Means for Solving the Problems]

 A gripper is fixed to the upper end of the upper shaft of the large diameter, a stone protrusion is provided at the lower end of the lower shaft of the small shaft, the middle shaft of the upper shaft is composed of a deformable shaft that can expand and contract, and after adjusting the length, each stage is adjusted. In a cane, a plurality of through holes are formed in the longitudinal direction of the shaft to fix the shaft, and a pin urged by a spring provided in the shaft is fitted into the through hole. One surface along the longitudinal direction of the circumferential surface of the shaft that constitutes the cane whose length can be adjusted is formed into a flat surface, and a plurality of through holes for fixing the flat surface after adjusting the length in the longitudinal direction are provided. It is used as a means to solve the problem by drilling.

[0005]

[Operation]

 The cane according to the present invention has a cane body composed of an upper shaft (3), a middle shaft (4), a lower shaft (5) and a telescopic shaft which can be extended and contracted. A plurality of through holes (7) are formed in the longitudinal direction, and a pin (9) urged by a spring (8) provided in the shaft is engaged with the through hole (7). One surface along the longitudinal direction of the shaft peripheral surface of the cane thus constructed is formed as a flat portion, and a plurality of through holes (7) are formed in the flat portion (10) in the longitudinal direction. Each shaft does not rotate. Therefore, if the shaft is adjusted to an appropriate length, the pin urged by the spring provided in the shaft will fit into the through hole (7), and the shaft will be fixed. On the other hand, when the engagement state of the shaft is released, if the pin (9) is pushed toward the center of the shaft, the pin is disengaged from the through hole (7), and each shaft can slide up and down. Also at this time, since one surface along the longitudinal direction of the peripheral surface of each shaft is formed as a flat portion, each shaft slides only in the longitudinal direction without rotating.

【Example】

 DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described. FIG. 1 shows a conventional wand configured with upper, middle and lower extensible warp shafts, and FIG. FIG. 3 shows a conventionally known fixing method of fixing each stage shaft after the length adjustment, and FIG. 3 is an explanatory view of the cane shaft of the present invention.

[0007] The wand of the present invention is constituted by an expandable and contractible warp shaft, and is provided with a plurality of through holes (7) along the longitudinal direction of the shaft to fix the shafts after adjusting the length. One surface along the longitudinal direction of each shaft peripheral surface, in which a pin (9) urged by a spring (8) provided in the shaft is fitted into and engaged with the through hole (7), is formed as a flat portion. A plurality of through holes (7) are formed in the longitudinal direction of the flat portion (10).

[0008]

[Effect of the invention]

 As described above, the cane of the present invention is configured with the upper, middle, and lower elongate warp shafts, and a plurality of shafts are provided along the longitudinal direction of the shaft to fix the shafts after adjusting the length. A hole (7) is formed, and a pin (9) urged by a spring (8) provided in the shaft is fitted into the through-hole (7). One surface along the longitudinal direction of the shaft peripheral surface is formed as a flat portion and a plurality of through holes (7) are formed in the longitudinal direction of the flat portion (100), so that the length is adjusted. At this time, since each shaft does not rotate, it can be adjusted simply by sliding up and down. On the other hand, when the engagement state of the shaft is released, since one surface along the longitudinal direction of the peripheral surface of the shaft is formed as a flat surface, each shaft slides only in the longitudinal direction without rotating, so that it is easy to perform. Can be canceled.
