CONTROL MECHANISM FOR AN ADJUSTABLE POSITION FURNITURE 1 Field of the Invention The present invention relates to a piece of furniture for reclining lying hereinafter referred to as position Background of the Invention Adjustable position furniture is composed essentially of a stationary supporting chassis to which there is linked an adjustable configuration framework consisting of articulated Some of these frameworks are mechanically or pneumatically more and more of them are operated and adjusted Electrical adjustment is effected by a powerful motor which moves the members of the framework with respect to each other and with the stationary chassis in at least the lateral sides of the framework are presenting a real danger to the limbs of nearby including the It is therefore a broad object of the present invention to ameliorate the danger of injury from electrically adjustable It is a further object of the present invention to provide an arrangement for governing the operation of an electric motor which adjusts the position of the framework of an electrically adjustable piece of the present invention provides a safety arrangement for an electrically adjustable piece of furniture for reclining lying said piece of furniture including a stationary supporting a movable framework composed of articulated metallic and an electric motor for moving said said safety arrangement comprising at least one electrically conductive strip conductively attached to at least those portions of said metallic members exposed to human and a control unit including a touch electrically connected to said framework for overridingly stopping the operation of said motor when said strip is touched during the movement of said 2 Brief Description of the Drawings The invention will now be described in connection with a certain preferred embodiment with reference to the following illustrative so that it may be more fully With specific reference now to the figure in it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiment of the present invention and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the In this no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the the description taken with the drawing making apparent to those skilled in the art how the several forms of the invention may be embodied in In the 1 is a schematic representation of a safety arrangement for electrically adjustable according to the present Detailed Description There is shown in 1 an adjustable piece of furniture a having a stationary supporting chassis a movable framework 6 composed of a plurality of per se known articulated metallic members a mattress a separate head support 12 and an electric motor Further shown is control unit 16 for controlling the operation of motor The metallic members 8 of framework and possibly also the are made of painted metal or any other material and are at least partly covered with a strip of conductive aluminum strip attached to members 8 by any suitable such as Control unit 16 consists of a touch a capacitive connected to and adapted to activate a latch module 22 in is adapted to 3 actuate a relay Relay 24 is connected to the power line of motor 14 so as to connect and disconnect the motor control unit 16 also includes a voice module so as to provide an audible alarm when the motor is deactivated upon receiving a signal from the touch Control unit 16 may be powered from an AC or DC power supply As can be 20 detects when someone touches the framework 6 when the motor is in and activates latch module which immediately activates relay causing the instant cessation of the a carelessly or inadvertently located in or on movable framework will automatically cause the interruption of the operation until the user will press reset switch The relay 24 remains in the disconnecting state as long as it does not receive a reset signal from latch module activated by reset switch thereby causing the return of power to motor It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrated embodiments and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes The present embodiments are therefore to be considered in all respects as illustrative and not the scope of the invention being indicated by the appended claims rather than by the foregoing and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced insufficientOCRQuality

Claims

144,231/2 WHAT IS CLAIMED IS:

1. A safety arrangement for an electrically adjustable piece of furniture for sitting, reclining and/or lying down, said piece of furniture including a stationary supporting structure, a movable framework composed of articulated metallic members, and an electric motor for moving said framework, said safety arrangement comprising: at least one electrically conductive strip conductively attached to at least those portions of said metallic members exposed to human touch, and a control unit including a touch sensor/switch electrically connected to said framework, for overridingly stopping the operation of said motor when said strip is touched during the movement of said framework.

2. The safety arrangement as claimed in claim 1, wherein said control unit includes a relay connectable to the power supply line of said motor, and wherein said relay is activated by said touch sensor/switch for disconnecting the power from said motor.

3. The safety arrangement as claimed in claim 1, wherein said touch sensor/switch is a capacitive touch switch.

4. The safety arrangement as claimed in claim 1, wherein said control unit further comprises an acoustic alarm activated by said touch sensor/switch.

5. The safety arrangement as claimed in claim 1, further comprising a reset switch for reactivating the motor by resetting said relay.

6. The safety arrangement as claimed in claim 1, wherein said conductive strip is an aluminum strip attached to said members by means of adhesive. 5 144,231/2

7. The arrangement as claimed in claim 2, wherein said control unit further comprises a latch module for activating said relay.

8. A safety arrangement for an electrically adjustable piece of furniture according to claim 1, substantially as hereinbefore described and with reference to the accompanying drawings. for the Applicant: WOLFF, BREGMAN AND GOLLER
