TW200820929A - An apparatus with alarm system to prevent user in bad sitting posture - Google Patents

Abstract

An apparatus to prevent user in bad sitting posture, which comprises several sets of sensors which located at many parts of a chair, say seat pad or back, where body will contact, an integrated control system which accept the signals from each sensor and provide output signals to enable alarm systems. Once the chair user lost his standard sitting posture or sitting too long, the system will alarm him to recover the posture or to leave seat after a period of time.

Description

200820929 IX. Description of the invention: [Technical field of the invention] The present invention is an tamper-evident warning device, which is mounted on a __ lin, which is mounted on a cushion of a seat cushion or chair f or an armrest. To help and mention the miscellaneous or shouting correct _. _ In the case of one person - too long, the day is guarded.

When the lang is in the correct sitting position, it will not be actuated, when the body is tilted left and right, etc., and when the user opens the side and leaves the sensing position for a distance: the sensor will act and the system will be activated. Integrate the lion control system to start the warning and raise the 翻 翻 岭 岭 岭 or the bright field vibration and other normal sitting posture. Once the user returns to the [Implementation] sub-ii mode device on the chair, when the user sits on the chair, the μ will sense the user's back and buttocks on the display of 5 200820929, and then send the signal to Integrate the control system (refer to Figure 5). If the detector finds that the user is not positioning, the system starts the timing device (refer to 礅7), and if the user does not resume positioning within the set time, the system will be activated. Refer to Figure 6 (6) until the user resumes positioning. w [Simple description of the drawings] Fig. 1 is a front view of the concept of the present invention. Figure 2 is a side view of the inventive concept. Figure 3 and Figure 4 are conceptual diagrams of the use of the present invention. Figure 3 shows that the system does not have any action when the user maintains the correct sitting posture. Figure 4 shows that when the user's sitting posture is poor, including leaning forward or left and right, the system will issue a warning after a set period of time to remind the user. Reply to the correct sitting position. [Main component symbol description]

Claims (1)

200820929 X. Patent application scope: 1. A sensing warning device that can be installed on a chair, including single or multiple sensing devices, which can be placed on the chair, back or armrest in an external or built-in manner; The system includes a logic operation, a timing unit, and the like, and processes the signal from the sensing device; and a warning reminding system to remind the messenger to return to the normal sitting posture; and a power supply system. 2. According to the sensing device of the first application scope of the patent application, the sensing principle may be contact type or non-contact type. The contact type sensing may be a touch switch, when an external force applies pressure to such a sensing element. The trigger signal will be activated; the non-contact sensing can be a device that generates a signal change using sound waves, electric waves or light waves or other physical and chemical principles. The above sensing device is intended to detect the position of the human body within a specific range. 3· Roots++Applications=Scope The second non-contact sensing device can be infrared or ultrasonic or local frequency radio waves, using the principle of absorption or reflection or refraction to detect the distance from the human body to the sensing device. Within the limits. 4, according to the scope of the second and third limits of the scope of application for patents, the specification is 90 centimeters. Zhongqing's integrated control device, which accepts and integrates the device from the application of the application, and then decides whether to use the time limit to change the warning command to the towel. Warning reminds you. · w 61 艮 According to the delay of the fifth item of the patent, the length is from 1 second to 60 minutes. 7. According to the integrated control device of the first paragraph of the patent application scope, Wake up the user's position of the placement of the person to make adjustments = according to the application of the 帛 - item of sensing device Can be used
