[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a walking stick according to an embodiment of the present invention. FIG. 2 is a side sectional view for explaining the mechanism of the stick in FIG. FIG. 3 is a partially enlarged side sectional view for explaining a control mechanism of a leg stepladder of the walking stick in FIG. 1. FIG. 4 is a partially enlarged side sectional view for explaining a control mechanism of a leg stepladder of the walking stick in FIG. 1. FIG. 5 is a plan view showing a state where the built-in stool of the walking stick of FIG. 1 is opened.

The walking stick shown in FIG. 1 basically includes a leg 1, a main body 2, and a grip 3 (see FIGS. 1 and 2).

A male screw 4 is formed at an end of the grip portion 3 on the body portion side so that the male screw 4 can be screwed into and removed from an end of the body portion 2 on the grip portion side.

The leg 1 is composed of three legs, and the three legs can be separated and opened and closed to a predetermined angle by the operation of the core bar 7 in the main body and the first spring mechanism. It is pivotally mounted on (inside) the end of the main body 2 on the leg side so as to be able to do so.

The main body 2 includes a first spring mechanism inside the cylinder 6 for opening and closing the leg 1 in three parts, and a leg for sliding the cylinder 6 slightly to open and close the leg 1. It is composed of a second spring mechanism that separates from and separates from the base 1, a core bar 7 that controls opening and closing of the leg 1, and a seating mechanism that can be opened.

A female screw 5 to be screwed with the male screw 4 of the grip 3 is formed at the end of the cylinder 6 on the grip side. Further behind the female screw 5, a stopper 8 for accommodating a ring spring 9 when the stool is pulled out from the cylinder 6 is provided. When the stool mechanism is pulled out of the cylinder 6, the ring spring 9 of the ring spring accommodating portion 10, which is a part of the withdrawal end of the stool mechanism, is accommodated in the stopper 8, thereby preventing the stool mechanism from being detached from the inside of the cylinder. The stopper 8 is a recess with a gentle leg side and an acute angle (inside the cylinder) on the gripping side, and the ring spring 9 can be freely stored and removed from the leg side, but can be further advanced toward the gripping side. There is no structure. The stool mechanism is basically composed of five seat bones 11 and seats 12 which are pivotally attached to the gripping portion side of the ring spring accommodating portion 10 so as to be bent outward by 90 degrees. A guide collar 13 is continuously provided on the leg side of the ring spring housing 10. A handle 14 for pulling the stool out of the cylinder is provided at the center of the seat 12 (when the stool is accommodated, the tip of the main body 2 inside the cylinder on the gripping portion side). The handle 14 has a structure and a thickness that can be lowered along the seat 12 so that the handle 14 is not obstructed when the stool mechanism is pulled out. When the handle 14 is pulled toward (to the outside of) the gripping portion and the seat 12, the seat bone 11, the ring spring housing 10, and the guide collar 13 are pulled out together, the seating mechanism (the guide collar 13) and the spring mechanism ( Fixing portion 15) is separated at the A-A portion. If the drawer is continued, finally, the ring spring 9 is housed in the stopper 8, and any further drawback is prevented, and the drawout of the stool mechanism is completed. Next, when the seat bone 11 is opened in an umbrella shape until it is perpendicular to the cylinder 6 (that is, horizontal when the stick is set up), the seat 12 is also opened at the same time, and the seat shown in FIG. 5 is formed. To store the stool in the cylinder, first close the seat bone 11 by hand, fold the seat 12, and then put the guide collar 13, the ring spring accommodating part 10, the seat bone 11, and the seat 12 together in the cylinder. Push in.

A core bar 7 is provided at the center of the axis of the main body 2. A knob 18 is provided at the end of the core rod 7 on the gripping part side. The tip of the core rod 7 on the leg side is tapered so as to be in contact with and separate from the head 16 of the leg 1 and restrict its opening and closing.

The first spring mechanism includes a coil spring 17 provided on the leg side of the fixed part 15, a pressing rod 20, and a pressing movable part 19. A fixing portion 15 is formed on the leg side in contact with the guide collar 13 in the cylinder, and the fixing portion 15 is fixed to (inside) the cylinder 6 with screws. A coil spring 17 is provided on the leg side of the fixed portion 15 in the cylinder, and the coil spring 17 moves by pressing the pressing movable portion 19 formed on the leg side of the coil spring 17 toward the leg side. Further, the other end of the pressing rod 20 provided so as to be connected to the pressing movable portion 19 acts on the head 16 of the leg 1 to open the leg 1. The pressing rods 20 connected to the pressing movable portion 19 are provided (three) corresponding to the number of the legs 1. 23 is a pressing rod support.

The second spring mechanism includes a rod spring 21 provided on the leg side of the pressing movable portion 19, and a cylindrical stopper 22. A bar spring 21 is fixedly provided on the leg side of the pressing movable portion 19 in the tube, and a tube stopper 22 is fixedly provided at the tip (lower end) of the bar spring 21. The bar spring 21 always presses the cylinder stopper 22 from the cylinder side to the core rod side.

The second spring mechanism controls the sliding of the cylinder 6. That is, a groove 25 having a certain length is formed in the cylinder side (middle) of the pressing rod support portion 23 so as to be able to slide the cylinder 6 only within a certain limited range, so as to be vertically long. A projection 24 is provided inside the cylinder 6 so that the cylinder 6 can slide within the length of the groove 25.

Next, the opening and closing of the leg 1 will be described with reference to FIGS. First, the gripper 3 is removed, the stool mechanism is pulled out, the seat 12 is opened to form a stool, and then the core bar 7 is pulled out with the knob 18 to the seat 12, and the bar spring 21 acts. The cylinder stopper 22 moves to the side of the core rod from which the cylinder 6 has been detached, and the cylinder 6 is slid toward the gripping part only within the range of the groove 25 so that the tip of the cylinder 6 at the leg side and the tip of the leg 1 at the main body side are moved. At the same time that a gap is created that does not hinder the opening of the leg 1, the tip of the core rod 7 on the leg side separates from the head 16 (of the leg 1), and is acted on by the coil spring 17 (the pressing movable portion). 19)) The pressing rod 20 presses the head 16 of the leg 1, and the leg 1 is opened. In order to close the leg 1, first, the three open legs are closed (by hand so as to be the tip of one stick) and then the cylinder 6 is slid to the leg side. What is necessary is just to push the core rod 7 protruding to the grip part side to the leg part side.
