BACKGROUND1. Field of Invention
This invention relates to devices designed to help promote proper posture when sitting.
2. Description of Prior Art
With a majority of people spending time in a sitting position on a daily basis, whether in front of a computer or sitting in a car, it is increasingly important to promote good posture. This is especially true in work environments where productivity and health are a concern for employers.
Typically the method of monitoring posture has been implemented in one of two ways. On uses a device attached to a users back that monitors the curvature of the spine. The other is incorporated into the structure of the seat or chair and monitors the back as it contacts the backrest.
Attached posture devices like that of U.S. Pat. No. 6,146,312 to Sclichter require the user put on the device and activate it upon every use. They can be bulky and awkward and may even interfere with the user comfortably sitting in a standard chair. Such devices also must be battery powered or constantly unplugged every time the user gets up.
Devices incorporated into an existing chair such as U.S. Pat. No. 6,669,286 to lusim are inherently expensive. A user must replace their existing seat or chair with one that has incorporated the posture correcting device. In an office or large business this would be extremely expensive and the most desirable models of seating may not be offered with the posture device installed. In addition, incorporating the device into an automobile seat would be extremely expensive due to the complexity and diversity of models and manufactures.
SUMMARYA portable posture measuring and indicating device consisting of a backrest pad with sensors and a control box with selector and alarm.
Objects and AdvantagesThe objects and advantages of this invention directly address the problems outlined above and offer increased functionality not yet mentioned.
Several objects and advantages of the present invention are:
-
- (a) to provide a method of detecting posture in a device that is portable and able to be used with virtually any chair or seat, including automobile seats;
- (b) to provide a method of detecting posture in a device that uses a minimal amount of sensors and basic electronics which lowers cost;
- (c) to provide a method of detecting posture in a device that can run on battery power or be plugged in to increase operation time;
- (d) to provide a method of detecting posture in a device that uses visual, audible, and tactile indicators of posture for maximum effectiveness;
- (e) to provide a method of detecting posture in a device that automatically shuts off when a user gets up, allowing freedom of movement without the hassle of unplugging or remembering to turn the device off;
- (f) to provide a method of detecting posture in a device that will gradually train users to maintain proper posture when not in use;
- (g) to provide a method of detecting posture in a device that can also be incorporated into computer interfaces allowing more advanced features.
The operation of the inventions begins by placing it on a desired seat or chair 14 and if applicable enclosing said chair with straps 20. The device is placed so that as many sensors 12 as possible are on the back of the chair 14 facing the user. The selector switch 26 is then rotated from the off position to one of the three operating positions. Position 1 utilizes all four sensors 12 as in
Position 1 operation: When using position 1, the user is required to maintain contact with all four sensors 12 to be in proper posture position. When the user is properly seated and contacting all four sensors 12, the invention is activated but the light 28 and speaker 30 are not active. When the user breaks contact with any of the four sensors 12 but still remains in contact with at least one sensor 12 the light 28 is activated and the circuit board 40 begins counting down approximately five seconds. If the user returns to proper posture position before the five seconds has elapsed, then the light 28 is deactivated and the countdown stops. If the user remains out of proper posture position for more than five seconds then the light 28 remains on and the speaker 30 is activated, producing a tone. This should prompt the user to return to a proper posture position. However, if the user gets up, completely breaking contact with all four sensors 12 then the unit turns off until any of the sensors 12 are contacted again.
Position 2 operation: Position 2 is used when a chair 14 has a lower back and the topmost sensor 12d will not be in contact with the back of the user. In this operation only sensors 12a, 12b and 12c are required to be contacted for proper posture and operation is the same as in position 1.
Position 3 operation: Position 3 is used on chairs 14 that have a back that does not continue from the seat of the chair to the top of the backrest as in many office or computer chairs as shown in
The invention operates on battery 42 power or can be connected to an AC adapter through an AC power receptacle 38. The invention can also be connected to a computer via the computer port 34 to allow onscreen display of posture status.
CONCLUSION, RAMIFICATIONS, AND SCOPEIt is concluded that the posture correction apparatus of the invention is a convenient, portable and inexpensive device that can be used by anyone on almost any seat where proper posture is desired.
While my above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of one preferred embodiment thereof. Many other variations are possible. For example, the control box could contain a wireless transmitter allowing the elimination of a power cord and allowing another method of integration with a computer interface. The control box could also be attached to the back of the back pad. The power cord can also be replaced with a standard 12 volt cigarette lighter plug for use in automobiles.
Accordingly, the scope of the invention should be determined not by the embodiment(s) illustrated, but by the appended claims and their legal equivalents.
Claims
