Abstract
An ambulation aid warning device for warning the uses when an ambulation aid is about to be used improperly. The device includes one or more gravity sensitive switches to activate an auditory, visual and/or sensory alarm when the ambulation aid is tilted beyond a specified angle.
Claims20
An ambulation aid warning device for alerting a user when the ambulation aid is tilted beyond a specified angle for proper use, comprising:
- a case for attachment to an ambulation aid;
- a power source attached to the case;
- one or more gravity sensitive switches attached to the case whereby gravity causes at least one switch to close when the ambulation aid is tilted beyond a specified angle for proper use;
- a warning indicator;
- and
- an electrical circuit connecting the power source, the gravity switch(es)and the warning indicator for activating the warning indicator when one or more of the gravity switches are in a closed position thereby alerting the user so improper use will not occur.
An ambulation aid having a warning device for alerting a user when the ambulation aid is tilted beyond a specified angle for proper use, comprising:
- a power source attached to the ambulation aid;
- one or more gravity sensitive switches attached to the ambulation aid whereby gravity causes at least one switch to close when the ambulation aid is tilted beyond a specified angle for proper use
- a warning indicator attached to the ambulation aid;
- and
- an electrical circuit connecting the power source, the gravity switch(es) and the warning indicator for activating the warning indicator when one or more of the gravity switches are in a closed position thereby alerting the user so improper use will not occur.
A method for warning the user of an ambulation aid about improper use of the aid comprising:
- installing an warning device on the ambulation aid wherein the warning device has a power source attached to the ambulation aid;
- one or more gravity sensitive switches attached to the ambulation aid whereby gravity causes at least one switch to close when the ambulation aid is tilted beyond a specified angle for proper use;
- a warning indicator attached to the ambulation aid;
- and an electrical circuit connecting the power source, the gravity switch(es) and the warning indicator for activating the warning indicator when one or more of the gravity switches are in a closed position thereby alerting the user so improper use will not occur.
An ambulation aid having a warning device for alerting a user when the ambulation aid is not properly positioned for use, comprising:
- a case for attaching to the ambulation aid;
- power source attached to case;
- a plurality of mercury switches held at an angle by one or more adjustable switch mounts, said switch mount(s) being attached to the case and being adjustable so the angle of each mercury switch may be adjusted to close said switch when the ambulation aid is tilted beyond a specified angle;
- a warning indicator attached to the case;
- and
- an electrical circuit connecting to the power source, the mercury switch(es) and the warning indicator, said warning indicator activating when a mercury switch is in a closed position to alert the user when the ambulation aid is not properly positioned for use.
