This enables the two ends of respective pairs of bars 4, 5; 6, 7 to be moved towards and away from each other in a scissor-like fashion and therewith move the frame-like part 1 vertically.
- the frame-like part 1 nd bars of the illustrated embodiment are made of varnished or lacquered steel plate and the frame-like part includes four bars 13-16 disposed in the form of a rectangle.
- the stand may, of course, be made of some other material and the frame ⁇ like part 1 may have the form of a square.
- At least two of the frame bars, the longitudinally extending bars 14, 15 of the illustrated embodiment have a substan- tially U-shaped cross-section with the legs of the II facing inwards.
- the upper transferse rods 9, 11 of the two leg members 2, 3 are intended for coaction with the frame bars 14, 15.
- the one rod 9 is pivotally mounted in the bars 14, 15, whereas the other transverse rod 11 is provided at both ends with suitable means for sliding in the U-shaped part of the bars in order to achieve the aforesaid scissor-like movement of the leg members.
- An essential feature of the invention is that a block- able gas-spring 17, or piston-cylinder device, is provided for enabling the position of the frame-like part 1 to be adjusted vertically in a smooth continuous fashion, both in an upward and in a downward direction.
- the gas-spring includes a bottom part 18 which is pivotally connected to the leg member 3 beneath the pivot rod 12, and an upper part 19 which is pivotally connected to the transverse frame-bar 15 on the same side of a vertical plane passing through the rod 12 as 5 the lower part 18 (see also Figures 3, 4).
- the gas-spring 17 is provided with a centrally posi ⁇ tioned pin 20 which protrudes slightly from the upper part 19 of the gas-spring in an axial direction. This 20 pin 20 is intended to activate a release valve provided within the gas-spring.
- the pin 20 is intended to coact with a cylindrical bushing 21 which is pivotally connected to a holder
- the leg member 3 includes two parallel bars or rods 6, 7.
- the bottom part 18 of the gas-spring 17 is therewith pivot ⁇ ally connected to a transverse rod 25, which mutually 5 connects the bars or rod 6, 7 and which is positioned beneath the hinge or pivot rod 12.
- the operating means 24 has an elongated shape and has a handle 26 provided on the rear thereof and a part 27
- the part 27 is provided with a hole 28 by means of which the operating means is pivotally conencted to the holder means 23 substantially immedi ⁇ ately above the pivot 22 for attachment of the bushing
- the forward part 27 of the operating means 24 is also provided with a concave recess 29 which is intended to abut the end of the pin 20 and which in ⁇ cludes substantially 90 ⁇ of a circle.
- valve in the gas-spring will open.
- the gas-spring is thereby compressed with a force which is greater than the resistance exerted by the gas-spring, which takes place when the stand is to be pressed down to a low level. If it is wished to maintain the stand at this
- the pin 20 is pressed-in by means of the operating means 24, thereby raising the frame part of the stand to the desired position, whereafter the pressure on the pin 20 is removed.
- each leg member may consist of a single rod instead of two mutually connected rods, as illustrated in the described embodiment.

Abstract
L'invention concerne un support de table destiné à être utilisé de préférence dans des caravanes ou des autocaravanes. Ledit support est pourvu d'une partie formant un châssis sur laquelle on peut placer un plateau de table et il est réglable en hauteur de sorte que le plateau de table peut être mis dans différentes positions, dans le sens vertical. Selon l'invention, ce nouveau support combine les différentes caractéristiques énoncées ci-après. Ledit support comporte au moins deux pieds (2, 3) qui sont articulés ou assemblés de façon qu'ils puissent pivoter, cela permettant d'éloigner ou de rapprocher l'une de l'autre, comme les lames d'une paire de ciseaux, les parties desdits pieds situées de part et d'autre de l'axe ou du pivot (12). Chaque pied (2, 3) est pourvu à chacune de ses extrémités d'une barre transversale (8, 9; 10, 11). Les barres inférieures (8; 10) servent à supporter le support sur une surface d'appui, tandis que les barres supérieures (9; 11) coopèrent avec la partie (1) formant un châssis de façon que les parties des pieds (2, 3) se trouvant sur les côtés opposés par rapport au pivot puissent être rapprochées ou éloignées l'une de l'autre pour élever ou abaisser la partie (1) formant un châssis par rapport à la surface d'appui. Un dispositif (17) à gaz et ressort ou piston et cylindre est monté sur le support de façon à permettre le réglage vertical de la partie (1) formant le châssis dudit support, ce aussi bien vers le bas que vers le haut. Le dispositif à gaz et ressort peut être bloqué dans la position fixée de façon que la partie formant un châssis garde sa position et que, par conséquent, la position du plateau de la table par rapport à la surface d'appui soit également maintenue.The invention relates to a table stand preferably for use in caravans or motor homes. Said support is provided with a part forming a frame on which a table top can be placed and it is adjustable in height so that the table top can be put in different positions, in the vertical direction. According to the invention, this new medium combines the various characteristics set out below. Said support comprises at least two legs (2, 3) which are articulated or assembled in such a way that they can pivot, this making it possible to move them further or closer to each other, like the blades of a pair of scissors. , the parts of said feet located on either side of the axis or of the pivot (12). Each foot (2, 3) is provided at each of its ends with a transverse bar (8, 9; 10, 11). The lower bars (8; 10) serve to support the support on a support surface, while the upper bars (9; 11) cooperate with the part (1) forming a frame so that the parts of the legs (2, 3) located on the opposite sides with respect to the pivot can be moved closer or further apart to raise or lower the part (1) forming a frame with respect to the support surface. A gas and spring or piston and cylinder device (17) is mounted on the support so as to allow the vertical adjustment of the part (1) forming the frame of the said support, both downwards and upwards. The gas and spring device can be locked in the fixed position so that the part forming a frame keeps its position and therefore the position of the table top with respect to the support surface is also maintained.
