Description

Technical Field

[0001] The present invention relates to the technical field of poles, in particular to a folding pole, and more particularly to a buttonless folding pole suitable for various poles such as mountaineering poles, ski poles, and walking poles. Background Art

[0002] Existing hiking poles, ski poles, and other poles are primarily used to assist walking and provide support. Traditional poles are mostly one-piece, which can be long and bulky, making them inconvenient to store and carry. To address this, a variety of retractable or foldable poles have emerged. Retractable poles typically consist of a main tube and an extension tube, which are retracted and positioned using a telescopic positioning device to reduce their size. However, these poles are complex and expensive. Folding poles, on the other hand, typically consist of multiple sections connected by elastic cords. While these are simpler in structure and easier to fold and store, they cannot be adjusted in height.

[0003] Upon investigation, the Chinese utility model patent number 200720058870, "A Foldable Cane Shock-Isolating Structure," was found. The cane comprises a first section, a second section, and an elastic drawstring. The elastic drawstring extends through the central holes of the first and second sections to pull and connect the first and second sections. An internal step is provided within the central hole of the first section, and a compression spring is positioned within the slot of the second section's butt-jointed end that engages the first section. The butt-jointed end of the first section engages the compression spring, creating a relative axial floating relationship between the second section and the first section. A locking point on the elastic drawstring engages the internal step of the first section, causing the elastic drawstring to contract, pulling the first section toward the second section. This foldable cane has a simple structure and can be folded for easy storage. However, like existing folding canes, it is only foldable and cannot be adjusted in height.

[0004] In addition, most existing telescopic rods use a button structure to unlock the locking mechanism. The button is set on the side of the rod, which not only affects the appearance but is also easy to be bumped, resulting in misoperation. Summary of the Invention

The lower end of the inner plug 20 is provided with a tapered hole 201, and the upper end of the fastener assembly 5 is provided with a tapered surface 50a. When the telescopic locking mechanism 4 is opened and the lower rod body assembly 3 is retracted into the upper rod body 1, the inner plug 20 and the tapered surface of the fastener assembly 5 are pressed against each other, so that the fastener assembly 5 is separated from the upper end pipe mouth of the lower rod body assembly 3, the rope b is loosened, and the rods of the lower rod body assembly 3 can be pulled out and folded.

[0034] The specific structure is as follows: the lower rod body assembly 3 of this embodiment includes a first rod body 31, a second rod body 32 and a third rod body 33 which are sequentially plugged in from top to bottom, wherein the upper ends of the third rod body 33 and the second rod body 32 are respectively formed with a reduced diameter section which cooperates with the lower ends of the first rod body 31 and the second rod body 32. After the three rod bodies 31, 32 and 33 are plugged in, they are tightened and fixed into one body by a rope b. The rope b can be a plastic-coated steel wire rope. The upper end of the first rod body 31 is provided with a first pipe plug 310, and the upper end of the second rod body 32 is provided with a second pipe plug 320. The first pipe plug 310 and the second pipe plug 320 are provided with through holes for the rope b to pass through. The fastener assembly 5 includes a fastener body 52 and a metal sheet 51, wherein the fastener body 52 is cylindrical and is arranged in the first rod body 31. A strip metal sheet 51 is vertically provided on one side of the upper end of the fastener assembly 5, which can be deformed left and right. A flat hole 53 is eccentrically opened on the fastener body 52 for the strip metal sheet 51 to pass through. A fastener 50 is fixed at the upper end of the strip metal sheet 51. The fastener 50 passes through the first pipe plug 310 and is limited by the pipe mouth. The outer end face of the fastener 50 is a downwardly inclined conical surface 50a. When the lower rod body assembly 3 shrinks into the upper rod body 2, the tapered hole 201 of the inner plug 20 is pressed against the tapered surface 50a, so that the fastener 50 is separated from the pipe mouth, thereby loosening the rope b.

[0035] The upper end of the drawstring a is connected to the inner plug 20. The fastener assembly 5 and the first tube plug 310 each have through-holes 55 for the drawstring a to pass through. The lower end of the drawstring a is provided with a stopper protrusion a1.

The upper end of the drawstring a passes through a small hole in the inner plug 20 and is held in place by the stopper protrusion a2. The fastener assembly 5 also has a through-hole 54 for the upper end of the rope b to pass through. The upper end of the rope b passes through the through-hole 54 and is held in position by the stopper protrusion b1 against the upper end of the fastener assembly 5. The third rod 33 is a tapered tube. The elastic structure 6 is located at the upper end of the third rod 33. The end of the second rod 32 is sleeved over the upper end of the elastic structure 6 and engages with the third rod 33. The elastic structure 6 includes a long plug tube 61, a connecting tube 62 and a spring 63. The lower end of the long plug tube 61 is provided with a reduced diameter external thread section, and the connecting tube 62 is connected to the long plug tube 61 by a threaded connection. The lower opening of the long plug tube 61 and the lower opening of the connecting tube 62 are respectively provided with plugs 65 and 66. The long plug tube 61 and the plugs 65 and 66 are provided with through holes for the rope b to pass through. The lower end of the rope b is provided with a limiting protrusion b2. The lower end of the rope b passes through the long plug tube 61, the plug 65, the connecting tube 62, and the plug 66, and is limited by the limiting protrusion b2 and the plug 66. The spring 63 is sleeved outside the rope b and is arranged in the connecting tube 62. The upper end of the spring 63 is against the lower end plug 65 of the long plug tube 61, and the lower end of the spring 63 is against the lower end plug 66 of the connecting tube 62, so that the rope 6 has a tendency to always move downward and be tightened. A fixed sleeve 64 is mounted on the outer surface of the connecting tube 62. The lower end of the connecting tube 62 is provided with an outer edge 621 that abuts against the lower end of the fixed sleeve 64, as well as a positioning protrusion 622. The lower end of the fixed sleeve 64 is provided with a corresponding positioning recess 641. The length of the fixed sleeve 64 is greater than that of the connecting sleeve 62. During assembly, the fixed sleeve 64 is mounted on the outer surface of the connecting tube 62, with its lower end plugged into the lower edge of the connecting tube 62 for positioning. The long plug tube 64 is inserted into the fixed sleeve 64 and threadedly connected to the connecting tube 62. After assembly, the elastic structure 6 is inserted into the upper end of the third rod 33 and fixed with glue. This elastic structure is primarily intended to facilitate adjustment of the elasticity and installation position of the elastic structure, as well as facilitate its secure installation.

[0036] In order to facilitate manufacturing, the limiting protrusions a1, a2, b1, and b2 are usually formed by riveting and fixing a metal sleeve on the pull rope a or rope b. In addition, rope b is covered with a metal sleeve below the fastener assembly and riveted and fixed as a limiting part.

[0037] The telescopic locking mechanism 4 includes a connecting sleeve 41 and a locking member 42. The connecting sleeve 41 is divided into two parts, the upper part is cylindrical, and the lower part is a longitudinally open elastic sleeve structure. The outer diameter and inner diameter of the upper part are both larger than the outer diameter and inner diameter of the lower part, and the upper inner diameter matches the outer diameter of the upper rod body 2, and the lower inner diameter matches the inner diameter of the upper rod body 2. The lower end of the upper rod body 2 is inserted into the connecting sleeve 41 through size matching and positioned against the step surface. The upper end of the first rod body 31 passes through the connecting sleeve 41 and is inserted into the upper rod body 2. The locking member 42 is a snap ring type. The locking member 42 is circumferentially arranged on the outer periphery of the lower part of the connecting sleeve 41, that is, outside the elastic sleeve structure, to lock and fix the lower part of the connecting sleeve 41 to the first rod body 31. Usually, the locking member 42 adopts an open ring sleeve, and a connecting pin 43 is connected to the open part. The end of the connecting pin 43 is connected to a cam wrench 44.

[0038] An inner hole with an opening at the lower end is provided in the handle 1, and an inner tube 10 is embedded on the inner wall of the inner hole. The upper end of the upper rod body 2 is inserted into the inner tube 10 and fixed. A bayonet 11 for inserting the buckle of the wristband is provided on the rear side of the upper end of the handle 1. A corresponding opening 101 is provided at the upper end of the inner tube 10, and a clamping part 9 for fixing the buckle is provided at the opening. The inner plug 20 is arranged in the upper rod body 2, and the upper end of the inner plug 20 is fixed against the clamping part 9.

[0039] The lower end of the third rod body 33 is connected to the plastic pointed foot 8, the tungsten steel pointed foot 80 and the foot cover 7 in sequence, wherein the upper end of the plastic pointed foot 8 is fixedly socketed with the lower end of the third rod body 33 by size matching, and the tungsten steel pointed foot 80 is inserted into the lower end of the plastic pointed foot and fixed by the foot cover 7.

[0040] When assembling and using, first plug the three rods 31, 32 and 33 of the lower rod assembly 3 together, then pull it down with force, pull the fastener assembly 5 through the pull rope a, and elastically deform and compress the elastic structure 6 through the rope b, so that the fastener 50 of the fastener assembly 5 is exposed outside the pipe mouth of the first rod body 31. The eccentrically arranged strip metal sheet 51 is deformed laterally, so that the fastener 50 on the fastener assembly 5 fastens the pipe mouth to form a whole, and then forms a telescopic structure with the upper rod body 2, and the length is adjustable. After it is adjusted into place, it is locked and fixed by the telescopic locking mechanism 4 to become a pole with appropriate height;

[0041] When not in use, it can be folded up, specifically: open the locking piece 42 of the telescopic locking mechanism 4, and retract the lower rod assembly 3 into the upper rod body 1. When it is retracted into place, the inner plug 20 in the upper rod body 2 and the conical surface 50a of the upper end fastener 50 of the fastener assembly 5 are pressed against each other, so that the fastener 50 is separated from the upper end pipe mouth of the lower rod body assembly 3, the rope b is loosened, and the three rod sections 31, 32 and 33 of the lower rod body assembly 3 can be pulled out and folded.

[0042] This embodiment describes in detail how the lower rod assembly 3 is composed of at least two foldable rods that are tightened and connected by a rope b, a fastener assembly 5 and its elastic structure 6. However, the structure of this elastic fastener combined with the rope can be varied. The rope b and the elastic structure 6 can be combined, and a similar effect can be achieved by using an elastic rope to replace the rope b and the elastic structure 6.

[0043] Moreover, the elastic structure 6 is not limited to being set at the upper end of the third rod 33, but can also be arranged below the fastener assembly 5, that is, at the position of the first rod 31, or in the middle part of the rope b, so that a similar effect can be achieved at any position of the first rod 31 and the second rod 32.

[0044] Finally, to further simplify the structure, the elastic structure 6 can be replaced by a tension spring.

[0045] This embodiment discloses the best implementation scheme of the telescopic locking mechanism of the automatic telescopic pole, which should not be understood as limiting the scope of protection of the present invention. Any replacement using equivalent or similar technical means to achieve rotation is within the scope of protection of the present invention.
