In addition, there was a problem that sensitivity adjustment was difficult. Further, in the switch using the liquid, there is a problem that when the cane is moved up and down, the liquid jumps to easily cause a malfunction.

An object of the present invention is to provide a cane with a tilt switch that has a simple structure, is easy to adjust the sensitivity, and can prevent malfunctions as much as possible.

[Means for Solving the Problems] The structure of the present invention for achieving the above object will be described below.

According to the invention of claim (1), a tilt switch that is turned on when the cane body is tilted and an angle between the cane body and a horizontal plane is a predetermined angle or less, and a voice connected in series to the tilt switch. In a wand in which a display and a battery for supplying power to a series circuit of the tilt switch and the voice display via a power switch are assembled, the tilt switch is an insulating cylinder incorporated in the main body of the wand. A body, a ring-shaped fixed contact held on the inner circumference of the insulating cylinder, an insulating support provided on the upper part of the insulating cylinder, and a position substantially on the axial center of the insulating cylinder. A pendulum type movable contact suspended from an insulating support through a lead wire at a position approximately at the height of the ring-shaped fixed contact, and a size and weight larger than the pendulum type movable contact. And hang it under the pendulum type movable contact. A weight for sensitivity reduction suspended via a reed wire, a lower support provided at the lower part of the insulating cylinder, and a slack between the weight for sensitivity reduction and the lower support. It is stretched, and is constituted by a weight excess rise preventing line for preventing an excessive rise of the sensitivity lowering weight.

The invention of claim (2) is characterized in that, in claim (1), the cane body is assembled with a blinking light and a manual switch for controlling power supply from the battery to the blinking light. And

The invention of claim (3) is the device of claim (1) or (2), wherein the battery is a secondary battery, and the cane body has a jack for charging the secondary battery. It is characterized by being

The invention of claim (4) is characterized in that, in any one of claims (1) to (3), the cane body is a crutch body.

[Operation] Since the tilt switch of the cane according to claim (1) has a structure in which a weight for lowering sensitivity is suspended below a pendulum type movable contact via a suspension wire, the cane is in a vertical state or the like. At this time, even if horizontal vibration is applied to the tilt switch, the sensitivity lowering weight comes into contact with the insulating cylindrical body, but the pendulum type movable contact has a smaller amplitude due to the action of the sensitivity lowering weight and the ring-shaped fixed contact. Since it cannot be touched and the switch is not turned on, the voice display does not display a voice during normal walking, and malfunctions can be prevented.

When the cane is tilted below a predetermined angle (an angle with the horizontal plane), the pendulum type movable contact comes into contact with the ring-shaped fixed contact due to its gravity, which causes the switch to be turned on and the voice indicator displays voice. .

In this case, the sensitivity adjustment can be easily performed by changing the weight of the sensitivity lowering weight.

Also, if there is a slack between the weight for lowering sensitivity and the lower support, and a weight excess rise prevention line is stretched, even if the cane is turned upside down for some reason, the excess weight of the weight for sensitivity lowering is prevented. Since the excessive rise prevention line blocks, it is possible to prevent the situation where the sensitivity lowering weight enters between the pendulum type movable contact and the ring-shaped solid contact and cannot be pulled out.

The walking stick according to claim (2) has the function of the walking stick according to claim (1), and when the manual switch is turned on, the blinking light flashes, and at night, etc. It has a function to notify the other party.

The cane described in claim (3) has the function of charging the battery through the jack, in addition to the function of the cane of claim (1) or (2).

In the cane described in claim (4), the function of any one of claims (1) to (3) can be imparted to the crutch.
