A system for mounting writing tablets to armchairs includes a slide guide mounted inside the armrest of the armchair. The writing tablet is slidable on the slide guide between a concealed position inside the armrest and a projecting position outside the armrest. A support is rotatably attached to the armrest and includes an upper stop element that can be adjusted to ensure the writing tablet is horizontal when in use.
The invention relates to an anchoring foot for chairs positioned at desks, comprising a column (1) having a lower anchor (2) for securing same to the ground and an upper supporting element (3), rotatably coupled thereto, for securing the body of the chair (13). The supporting element (3) includes a carriage (7) which can move longitudinally along a guide (8) forwards and backwards in relation to the desk (17) and which can rotate in relation to the column (1). In addition, the supporting element (3) can include a lower cam (25) positioned facing another complementary upper cam (22) that is inserted therein by means of helical tracks (24). The lower cam (25) is pushed upwards by the return force of a spring (27), thereby rotating the upper cam (22) and rotating the seat to the initial position thereof.
Automatic rotation system for tilting seats of chairs or armchairs, wherein the fastening of the seat is by means of holders formed by two parts (1 and 2) which are coupled with relative rotation between same, and incorporate a helicoidal spring (5) which is hooked by its ends in traction assembly and exercises a relative rotation action between said parts (1 and 2), in an arrangement of said spring on a structure (6) in form of an annular drum, on which it has a clamping effect with a braking action on the rotation of the two parts (1 and 2).
Seat-assembly movement system, for collecting up and deploying rows of seats (1) at the installation site, by means of sliding on guides (2) arranged in the floor, the movement of the rows of seats (1) being managed by means of a control system comprising a master PLC or a computer unit, for governing the installation, in combination with respective slave PLCs arranged on the carriages (3) carrying the rows of seats and in connection with devices for controlling the position of said carriages (3) on the mounting guides (2).
The invention relates to a chair of the type that is positioned in rows together with other chairs, including a seat (3) which can pivot between a horizontal use position and a vertical folded position and a backrest (4) which is inclined backwards in the use position and which can also pivot between an inclined use position and a vertical folded position. The invention also includes a mechanism comprising a rod (5) and a push cylinder (7), which is associated with the backrest pivot system and which biases the backrest (4) into the vertical position.
The invention relates to an improved structure for armchairs, formed by seats (2) and backrests (3) which are mounted independently to a support frame (4). According to the invention, the seats (2) include a support formed by a metal frame covered with a plastic material and a cover sheet formed by a metal frame which is provided with internal springs and a foam cover. The backrests (3) include a support formed by a metal frame which is provided with internal springs and a plastic cover and a cover sheet formed by a metal framework covered with a layer of foam.
The invention relates to improvements to a system for mounting writing tablets to armchairs, of the type that is disposed on a slide guide (4) provided in the armrest (1) of the chair, such that the writing tablet (3) can slide between a concealed position in which it is concealed inside the armrest (1) and a projecting position in which it projects out from the upper part of the armrest. The ends of the course of the slide guide (4) are fitted with a lower elastic stop element (13) and an upper stop element provided on a support (15) that can be adjusted in order to ensure that the horizontal position of the writing tablet (3) is level in the use position.
The invention relates to a folding chair comprising a seat part (2) and a backrest (3) which are independent of one another. According to the invention, plates (4), which are disposed between the seat part and the backrest, are equipped with pins (4.1) which are inserted into recesses (5.1) that are provided in lateral supports (5), such as to form a tilting assembly which enables the seat part (2) and the backrest (3) to move together between a folded position and a use position.
The invention relates to a chair and table for conference halls and similar, comprising a backrest (3) which can be lowered onto the seat (2), combined with the movement of a table top (6) which can pivot between a vertical position and a horizontal position, said table top (6) being disposed on a variable-height column (5) which is fixed to the structure of the chair using a knuckle joint (16), such that the table top (6) can move forwards in the horizontal use position, thereby determining an anti-panic arrangement.
