[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a right side view of the three-wheel walking stick (A) according to claim 1 of the present invention. The support (1), the connecting body (2), the connecting member (3), the stopping means (10), and the like are combined. It is a relatively light and strong material such as a light metal or a hard plastic made of a combination of pipes and rods, and includes three rotating pieces (7), a handle (8), a stopping means (10), and an adjusting screw (6). ), Hooks (9) or rings (not shown) are preferably partially or entirely made of rubber or soft resin.

The shape of the three-wheel walking stick (A) of the present invention is such that a handle (8) having one rotating piece (7) inclined at a slight angle is integrated, and the length of the handle (8) is freely adjustable. (2) having a support (1) that can be adjusted to a height, and two rotating pieces (7) substantially rearward from the center of the support (1).
Is mounted on a part of the support body (1) so as to be rotatable and removable, so that disassembly and assembly can be easily performed.

The handle (8) at the tip of the support (1)
Has a moderate thickness that is easy to hold and an angle of 90 degrees or less, and the support (1) and the connecting body (2) are formed by the letter "H"
FIG. 8 is a partially enlarged view showing the connected state of FIG. 7, which is attached in a mold shape, and shows a state in which a connecting member (3) is fitted to a part of the support (1). The rotation range is restricted by the movement of the pin (5) in the annular body (4) by inserting the tip of the connection body (2) into the connection member (3) so as to be freely rotatable, and the height is as shown in FIG. Support (1) as shown on the left side view
The height of the support (1) can be adjusted only by loosening or tightening the adjustment screw (6) provided at the center of the support.

FIG. 5 is a plan view of the three-wheeled walking stick (A) of the present invention. Since the handle (8) is provided below the position range of the three rotating pieces (7), It can always be used in a stable state even on a road surface under some bad conditions.

FIG. 3 is a rear view of the three-wheel walking stick (A) of the present invention, showing a state in which a stopping means (10) is provided between two rear rotating pieces (7). As shown also, the distance between the three rotating pieces (7) and the contact surface such as the road surface is 15 mm or less, and the stopping means (10) is bifurcated on the left and right, but like a rake. There may be a plurality of stopping means (10).

A hook (9) is provided on a part of the support (1) so that baggage can be hung. However, a C-shaped ring (not shown) may be used. Hooks or rings may be attached to the top and bottom to secure the baggage so that it does not move.

With the above configuration, when using this, the handle (8) of the three-wheeled walking stick (A) of the present invention is held in a natural state, and the handle is directly under the three rotating pieces (7). By simply pushing the three rotating pieces (7) forward on a road surface or the like like a normal walking stick by pressing down, it is possible to walk without putting a burden on the body.

Since there is a center of gravity within the range of one rotating piece (7) in front and two rotating pieces (7) in the rear, which is a total of three rotating pieces (7), sideways fall is small and walking can be performed with ease. it can.

In particular, when adjusting the height of the support (1) of the three-wheeled walking stick (A), the support (1) has an appropriate length because it has an extendable structure. 7 can be fixed only by loosening or tightening the adjusting screw (6).

The three-wheeled walking stick (A) puts a burden on the body only by sliding the three rotating pieces (7) forward on the road surface, etc., without lifting it like a normal walking stick. The direction operation can be clearly grasped by one rotating piece in front, and the handle (8) can be easily operated with one hand.

When the vehicle is going down a hill or suddenly braked, the center of gravity naturally moves rearward by simply pulling the handlebar (8) backward to lift one of the rotating pieces in front, and the stopping means (10) ) Can stop the tricycle walking stick (A) without touching the body by touching the road surface,
The driving operation can be freely performed even if the reflex operation is slightly delayed.

As shown in the right side view of FIG. 1 and the left side view of FIG. 2, a hook (9) or a ring (not shown) is attached to a part of the support (1). 9) Even if it is hooked on a ring (not shown), the luggage will not stagger due to the luggage getting caught in the center of gravity,
There is no burden on the muscles such as the hips, arms, and knees.

Since the handle is provided so as to be below the position range of the three rotating pieces (7), it is always stable with one direction even on a road surface under a little bad condition. Can be used by anyone in the state.

The distal end of the connecting body (2) is attached to a part of the support (1) so as to be rotatable and removable, so that it is lightweight and can be easily disassembled and assembled. The cost of carrying and transporting by car is low and economical.

The three-wheeled walking stick (A) of the present invention does not burden the body by floating the three rotating pieces (7) forward on a road surface or the like without floating above a normal walking stick. It is only necessary to operate one handle (8) with a rotating piece with one hand without hanging.

When stopping down a hill or suddenly applying a brake, instead of lifting the two wheels as in the past,
By simply pulling the handle (8) backward to lightly float one of the rotating pieces in front, the center of gravity naturally moves rearward, and the stopping means (10) comes into contact with the road surface without burdening the body. The three-wheel walking stick (A) can be stopped and the driving operation can be freely performed.

Since there is a center of gravity in the range of one rotating piece (7) in front and two rotating pieces (7) in the rear, which is a total of three rotating pieces (7), it is possible to walk with ease without falling down. it can.

Since a hook (9) or a ring (not shown) is attached to a part of the support (1), even if the load is hooked on the hook (9) or the ring (not shown), the load is swung to the center of gravity. There is no swaying and the body swaying, and the muscles such as the hips, arms, and knees are not burdened.
