Abstract

The table has a top (1) and leaves (2) that are integral with a structure ended by a sliding square section tube (9) which telescopes with a central tube (4) forming part of a base (3). The central tube is secured to sections (5) having square tubes (6) at their ends that rest on adjustable feet (7). A screw (8) passing through the central tube allows the sliding tube to be locked. A gas actuator enables the table to be raised without effort.

Description

VARIABLE HEIGHT TABLE

  The present invention is in the field of furniture, particularly

  variable height and surface tables.

  In many apartments with a limited surface area, studios or other premises, it is necessary to have a multi-use table, coffee table, dining table or work table, This

  with a height and a tray of different dimensions.

  If there are office chairs whose height can be adjusted with locking in the desired position. (Height can vary with the help of a screw or a vertical push cylinder), there are only tables housewives moved with a screw, a rack or a deformable X-leg. In all cases these tables are either very expensive or not very stable. The object of the invention is to remedy these drawbacks by studying an inexpensive product of manufacture, very stable whatever the desired height, and this, in accordance with the requirements of the cammerce which wants that the largest dimensions of 1 packaging does not exceed those of the tray. In carrying out the invention, the parts serving as the base and the support for the plate were made of commercial steel profiles.20 The base itself consists of a tube of square section with at its

  lower part, on two opposite sides a U-profile which is welded to it.

  The whole does not form a T because the ends of the U-shaped profiles have been cut off at a slight angle. This design allows the central tube not to carry on the ground. Inside each of these U-shaped profiles, another U-shaped profile, of smaller section than the first, fits into it. They are assembled by bolts. At the end of each of these U, of smaller section, a tube of square section is welded. They thus form a T. These square section profiles come to rest on the ground and they can be provided, at each end, with feet with

set screw.

  The vertical tube has, at its upper part, at an angle, a hole on which a nut is welded. Through this nut passes a screw provided with a handwheel which allows the tightening of a square section tube which comes

  slide there. This sliding tube is part of the tray support.

  At the top of the sliding tube, a U-shaped profile is welded. With the

  tube, they form a T. At each end of the branches of the U, a square tube, perpendicular, is

  bolted (in T) via the flat iron welded to this square tube.

  These square tubes serve as slides for angles to which are fixed the table extensions which, in the stowed position, are located under

the main board.

  The assistance of the rise of the plate is ensured by a simple gas spring of the trade whose pushing pressure and slightly higher than that of the weight of the plate, extensions and their support. This allows that from the low position as soon as the screw or any other blocking system is loosened, the tray rises effortlessly from the user. To put it

  in the low position a simple push of the hand is sufficient.

  The gas spring has a screw at these two ends. One is fixed to the U-shaped profile located at the end of the mobile tube (square section)

  The other is attached to the bottom of the tube (square section) serving as a housing.

  accommodation to the previous one. The low point is limited by the stop of the upper part on the foot. The maximum height is limited by that of

  length of the gas spring, in the relaxed position.

  The present invention will be better understood and the details will appear,

  with reference to the single plate, by the description of a form of

  preferred embodiment, without this being limiting.

  FIG 1 represents the table, in perspective, showing

the different parts.

  The tray (1) with the extensions (2) in the storage position, the foot (3) composed of the central support (4) to which the bases (5) are fixed which end in tubes (6) which rest on the ground by feet

  adjustable (7). The screw (8) is used for locking the height position.

  FIG 2 shows the table in perspective showing the details of the assembly. Below the plate (1), on its long sides are housed the extensions (2). The drawing of the tray includes a tear-off which allows you to see the assembly. On the support (9) formed of a square section tube which slides in the central support (4), a U-shaped profile (10) is welded. In the center a hole (11) which allows the fixing of one of the ends of the gas spring (12). The other end of the gas spring is fixed at (13) at the bottom and in the center of the central support (4). The screw of - 2 -

  blocking (8) tightening on the angle of the square tube (9).

  A tear off of the plate (1) allows you to see the sliding system of

  extensions (2). The system is identical on both sides of the extensions.

  The extensions (2) are fixed to the profiles (15) by screws (14).

  The profiles (15) slide in tubes (16). These are integral with the central tube (9) by means of pieces (17) of flat iron which are assembled by bolting to the U-shaped profile (10) which is

welded to the tube (9).

  FIG 2 also gives the construction details of the base of the

  table. U-shaped profiles (5) are welded to the square section tube (4).

  The profiles (5) receive, inside, other U-shaped profiles (18) which are bolted to (19). At the end of each profile (18) is welded in T a tube of square section (6) which rest on the ground via

adjustable feet (7).

  Although particular and preferred forms have been described or depicted

  of the invention, it should be understood that this form and that the

  components of the description are not limiting and that together

  or separately they can be transposed to any other table.
