FR2890195A1 - Portable computer`s screen adjusting and positioning device, has arms connected between screen and body of machine by ball and socket joints, and electric, hydraulic or mechanical assistance provided for deploying arms - Google Patents

Abstract

The device has arms (1) that are connected between a screen and a body of a machine e.g. portable computer, by ball and socket joints (2). An electric, hydraulic or mechanical assistance deploy the arms. Housings (3) are incorporated in the screen and/or the body for retracting the arms. The arms connecting main axles are articulated and the arms in closed screen position are retracted partially or totally in the screen or in the body of the machine, where the arms are telescopic. A locking system is provided at the level of the main axles and/or of the arms for connecting the axles.

Description

The present invention relates to a positioning adjustment principle

  the laptop screen to improve ergonomics.

  Currently the screens of laptops are directly attached to the body of the machine. The hinge mode used does not allow, when open, to choose the height of the screen.

  The device according to the invention overcomes this disadvantage. It has indeed, according to a characteristic léfe, no longer an articulated axis but several, including two principal; the first of the two taking place on the body of the machine, the second on the screen itself, these two axes being themselves connected by one or more arms themselves may, depending on the particular embodiments, include secondary joints.

  The device thus described allows to open the screen in a conventional manner and if necessary, to move it away from the body of the machine to place it in a more ergonomic position. According to particular embodiments: The number of articulation points specific to each axis and therefore the number of arms, is not limiting.

  Each main or secondary joint may be of the ball joint type.

  É If only one arm is used, this type of joint (ball joint) is strongly recommended because it allows not only to move vertically, or obliquely, the screen but also to rotate it.

  In order to keep the screen in the same plane as the body of the machine and this whatever its distance from it: / The, or the arms, connecting the main axes can be articulated, / The, or the arms, in closed screen position, can retract in part, or completely, either in the screen or in the body of the machine or partly in each, / Le, or arms, can be telescopic.

  In order to facilitate the deployment of the mechanism (the, or arms) connecting screen and body of the machine, pneumatic, hydraulic, electrical or mechanical assistance can be used.

  A locking system may be incorporated into the machine at the two main axes and / or the mechanism connecting them to prevent any inadvertent movement of the screen whether it is in the open or closed position.

  This locking system can, in a second phase, release the arm or 35 in order to have access to all the positioning possibilities offered. This phase can be an activation of the, or assistance systems.

  2890195 -2- If one, or assistive systems are used, these can be double-acting: extension and retraction.

  If this or these assistance systems are single-acting, that is, only in extension, a single user-supplied counterforce can be used while reactivating them to re-engage their locking system. .

  The screen lock at the front of the apparatus may remain conventional or may, depending on the embodiments, activate the locking systems specific to the proposed innovation.

  The connection between the body of the device and the screen can pass in the or arm 10 or can be of wireless type.

  The accompanying drawings illustrate the invention: FIG. 1A represents in profile a possibility of open screen innovation but a mechanism that is barely deployed.

  Figure 1B shows in profile Figure 1A, mechanism deployed.

  Figure 2A represents another opportunity for open-screen innovation but a barely deployed mechanism.

  Figure 2B shows in profile Figure 2A, deployed mechanism.

  With reference to these drawings, the device comprises one or more arms (1) connected by hinges (2) between the screen and the body of the machine. Housings (3) may be incorporated in the screen and / or the body of the machine to retract the arm (s) (1).

Claims (2)

  1) Device for improving the ergonomics of laptops by adjusting the positioning of the screen characterized in that it comprises one or arms (1) connected by joints (2) between the screen and the body of the machine.   2) Device according to claim 1 characterized in that housing (3) may be incorporated in the screen and / or the body of the machine to retract the arm or arms (1).
