In the examples of conventional canes mentioned above, they are mainly used outdoors, and only a few canes have a function of switching between indoor and outdoor use. However, in order to use a cane that is used outdoors as it is indoors, there are issues that must be avoided due to common sense considerations such as hygiene and dirt. Regardless, I had to refrain from using a cane indoors.

In addition to the above, this invention is a cane that is used for walking by the elderly, the disabled, and the sick. To provide a cane for both indoor and outdoor use that can switch between the butts of

The indoor/outdoor cane of the present invention has a cane shaft (A1) having a ferrule (E1) at its lower end, and a cane shaft (A1) having a ferrule (E) at its lower end, which surrounds the cane shaft (A1) and is movable up and down. Equipped with a cylindrical pipe (B) and a grip (G) attached to the cane shaft (A1) or the upper end of the pipe (B), and the pipe (B) stops at at least two upper and lower stop positions. is provided, and when the pipe (B) stops at the upper stop position, the ferrule (E1) of the cane shaft (A1) protrudes from the pipe (B), and the pipe ( It is characterized in that the ferrule (E1) of the cane shaft (A1) is hidden in the pipe (B) when B) stops at the lower stop position.

The cane for both indoor and outdoor use can be switched between at hand without bending or stretching the body. It comes true, and you can move without worrying about others. It can be expected to reduce the burden of introverted minds such as staying indoors, and it can also be expected to be a solution to problems such as movement.

1 is a perspective view of an indoor/outdoor cane according to Embodiment 1 of the present invention. FIG. Fig. 2 is a front view of the stopper of the cane for indoor/outdoor use according to Embodiment 1 of the present invention; Fig. 10 is a perspective view of an indoor/outdoor cane according to Embodiment 2 of the present invention;

(Embodiment 1)
FIGS. 1(a) and 1(b) are canes used for walking. The cane of Embodiment 1 of the present invention consists of a cane body A consisting of a cane shaft A1 and a grip G attached to the upper end of the cane shaft A1 for gripping the cane, and a cylindrical body A that surrounds the cane shaft A1 and can move up and down. Pipe B and At the lower end of the cane shaft A1, there is a ferrule E1 in contact with the floor or the like, and at the lower end of the pipe B there is a ferrule E in contact with the ground or the like. For example, when using a cane indoors, as shown in FIG. Use with part E in contact with the floor or the like. On the other hand, when using the cane outdoors, the pipe B is moved upward as shown in FIG. It is used with the thrust part E1 in contact with the ground. Thus, the cane of the present invention is a cane for both indoor and outdoor use, in which the butt end E1 of the cane shaft A1 and the butt end E of the pipe B can be switched between indoors and outdoors.

Next, three specific stopping mechanisms for moving the pipe B vertically on the cane shaft A1 and stopping it at two positions on the upper side and the lower side will be described. A first stop mechanism will be described. As shown in FIGS. 2(a) and 2(b), the pipe B is provided with a stop hole a1 on the upper side and a stop hole a2 on the lower side. A push button O is provided on the side surface of the cane shaft A1. The push button O may have a structure in which the button retracts when pressed and pops out when released, or may have a structure in which the button remains retracted when pressed and returns to its original position when pressed again. When using the cane indoors, the pipe B is moved downward until the push button O comes to the position of the stop hole a1 and is stopped (lower stop position). When using the cane outdoors, the push button O is pushed in and the pipe B is moved upward until the push button O comes to the position of the stop hole a2 and stopped (upper stop position).

Next, the second stopping mechanism will be explained. As shown in FIG. 2(c), a stop lever L for stopping the pipe B is provided on the side surface of the cane shaft A1. A stop hole b1 is provided on the upper side of the pipe B, and a stop hole b2 is provided on the lower side. is provided. The groove M is shifted rightward from the center of the stop holes b1 and b2, so that the stop lever L can be moved to the left after moving to the position of the stop hole b1 or the stop hole b2 and stopped. For example, when using a cane outdoors, the pipe B is moved upward and stopped using the stop lever L at the position of the stop hole b2.

Next, the third stopping mechanism will be explained. As shown in FIG. 2(d), a push button O is provided on the side surface of the cane shaft A1, and the pipe B is provided with a retaining hole c1 on the upper side and a retaining hole c2 on the lower side. These structures are similar to the first stop mechanism. A different point from the first stop mechanism is that a screw H is provided to move the pipe B. The structure of the screw H is such that a thread h1 is cut over a predetermined range on the outer peripheral surface of the cane shaft A1, and a thread h2 is cut on the inner peripheral surface of the pipe B over a predetermined range. The reason why screws are used is to create a structure that has both a tight fit without creating a gap between the cane shaft A1 and the pipe B and a measure to prevent rapid up-and-down movement. The position of the screw is arbitrary as long as the above functions are provided, and is determined in consideration of ease of work and cost.

(Embodiment 2)
3(a) and 3(b) are diagrams showing a cane according to Embodiment 2 of the present invention. The cane of the second embodiment differs from the cane of the first embodiment in the mounting structure of the grip G. As shown in FIG. In the cane of the first embodiment, the grip G is attached to the upper end of the inner cane shaft A1, whereas in the cane of the second embodiment, the grip G is attached to the upper end of the outer pipe B. Since the structure of the cane shaft A1 and the pipe B, the stop mechanism of the pipe B, etc. are all the same as those of the first embodiment, detailed description thereof will be omitted. By adopting the configuration of Embodiment 2, in comparison with the cane of Embodiment 1, in the cane of Embodiment 2, the grip G is attached to the upper end of the outer pipe B, and the cane shaft A1 is located inside the outer pipe B. In addition to being more compact and lightweight and aesthetic sensibility, the interior has the merits of closeness.
