Abstract
A health chair includes a chair body, a pressure detection device located within the chair body for generating conduction signals at a conducting stage, wherein the conducting stage is triggered at a predetermined pressure, an alarm device, and a logic processing unit electrically connected to the pressure detection device and the alarm device for analyzing the conduction signals from the pressure detection device, so as to determine whether to trigger the alarm device and, thereby, to notify the user on the chair body.
Description
- 1. Field of the Invention
- The present invention relates to a health chair and, more particularly, to a chair, which is used in offices and has the functions of detection, operation and alarm to prevent a user sitting thereon from physical harms due to sitting for a long time.
- 2. Description of the Prior Art
- A person who sits in front of an office desk unavoidably maintains an almost still posture for such a long period of time, resulting in symptoms such as sore shoulder, cyrtosis and so on. According to medical research, periodically changing the sitting postures can keep some of these kinds of symptoms or injuries away. However, currently existent office chairs have no related specific designs to help people avoid aforementioned symptoms or injuries.
- The present invention is directed towards a health chair, which can prevent people from physical harms due to remaining seated too long. The present invention is characterized by the measurement of how long a person has been on the chair, with maintaining the same posture. If the time is too long and exceeds the time advised by doctors, a sound or vibration is generated, serving as a warning message, to inform the user on the chair of that it is right time to change his/her postures, while the measurement of calculating the time that the user has been on the chair continues. Once the user on the chair has changed postures, the accumulated time is going to be reset. Therefore, the present invention can prevent a chair user from physical harms due to sitting too long on the chair. To achieve the above object, in the present invention, a sheet-type conducting rubber film is placed in the cushion of a chair, and a logic processing unit is connected to an alarm device and electric contacts on the conducting rubber film, so as to obtain the information regarding how long that the user has been on the chair and maintained the same posture unmoved. If the positions of a considerable number of the electric contacts of the conducting rubber film within a certain period change, representing the user has changed his/her postures, and then reset the accumulated time which is for calculating how long the same posture of the user has maintained. If the accumulated time exceeds a predetermined value, meaning the user has maintained the same posture too long, and an alarm (sound or vibration) is generated to notify the user that it is the high time to change his/her postures.
- The above logic processing unit is a logic processor having functions of operating, power supply, and timing.
- The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing, in which:
- FIG. 1 is a perspective view of the present invention;
- FIG. 2 is a partly enlarged view of FIG. 1;
- FIG. 3 is a circuit block diagram of the present invention;
- FIG. 4 is a flowchart of the algorithm of the present invention; and
- FIG. 5 is a schematic diagram illustrating the conducting rubber film having a plurality of switching devices arranged thereon.
- As shown in FIGS.1 to 3, the present invention provides a health chair that is particularly for office use includes a chair body, a
pressure detection device 2, alogic processing unit 3, and analarm device 4. Thechair body 1 is designed in accordance with ergonomics. - The
pressure detection device 2 is a sheet-type conducting rubber film in this embodiment, and is placed in a cushion of thechair body 1. A plurality of switching devices are arranged on the conducting rubber film to form a switch array, as shown in FIG. 5. When an electric contact of any of the switching devices is subject to a predetermined pressure, conduction signals are sent to thelogic processing unit 3. - The above conducting rubber film is formed by arranging a plurality of
electric contacts 22 on afilm plate 21. Arubber switch 23 is provided at a position corresponding to that of each of theelectric contacts 22. A conductingportion 24 is provided at the bottom surface of each of therubber switches 23. When the conductingportion 24 contacts theelectric contact 22, a conducting stage is triggered. Thealarm device 4 is a buzzer or a vibrator. - The
logic processing unit 3 is connected to theelectric contacts 22 of thepressure detection device 2 and thealarm device 4, and has functions of operating, power supply, and timing. Thelogic processing unit 3 analyzes conduction signals from thepressure detection device 2 to determine whether to trigger thealarm device 4. - When a user sits on the cushion of the
chair body 1 to allow some of therubber switches 23 to contact some of the electric contacts of thepressure detection device 2, therefore to reach to a conducting stage and having the conduction signals sent out, thelogic processing unit 2 analyzes the conduction signals of thepressure detection device 2. If the user has changed postures so as to change the positions of a considerable number of theelectric contacts 22 of thepressure detection device 2 within a certain period, the accumulated time for recording how long the: user has been on the chair and how long he/she has maintained the same posture is going to be reset. If the accumulated time exceeds a predetermined value, meaning the user has maintained the same posture too long, and then the alarm device is triggered to generate a sound or vibration to notify the user it is high time to change his/her postures. - As shown in FIG. 4, the flowchart of the present invention comprises the following steps:
- Step41: All the devices/units are initiated.
- Step42: The timer is reset.
- Step43: All signals of the pressure detection device are read and sent to the logic processing unit for analysis.
- Step44: If the user is sitting on the chair, the flow proceeds to
Step 45; otherwise, returns toStep 42. - Step45: Whether it is necessary to reset the timer, which is to calculate the accumulated time the user maintains the same posture, and if the user sitting on the chair has changed positions of a considerable of electric contacts of the pressure detection device, the timer will be reset (go to Step 42); otherwise go to
Step 47, - Step46: Whether the user has maintained the same posture too long is determined, if yes, go to
Step 47; otherwise, returns toStep 43. - Step47: An alarm (sound or vibration) is generated to notify the user that it is high time to change his/her postures, and back then, the process returns to
Step 43. - To sum up, through the components and circuits arranged in the chair body and the operation rules; the present invention is to generate a warning to the user as he/she has maintained the same posture too long, thus to protect the user from physical harms due to sitting for work for a long time.
- Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
