Definitions

  • the present invention refers to a table having two or more retractable extensions.
  • the selection of a table having a fixedly shaped tabletop implies a thorough consideration of a number of factors, such as the place where to position it and the various furniture fittings which it has to be combined or matched with, to be made by the buyer before purchasing it.
  • buyers of a table of this kind following a change in their taste and preferences, or even owing to particular needs arising in terms of available space or house decoration, find out that a table having a different shape is what they would actually need. Whenever such considerations or newly arisen needs lead to a table being therefore replaced, this will most clearly involve - further to an unavoidable waste - an undesired disbursement to be sustained.
  • FIG. 1 to 3 So, for instance, quite popular on the marketplace is currently a table 20 out of this production (see Figures 1 to 3), which is provided with a protracting and retracting mechanism 26 for one or more extensions 22 enabling them to disappear - when retracted - under a tabletop 24 of the same table 20.
  • the extension 22, which - when brought in its protracted position - comes to lie in the same plane as and juxtaposed to the fixed tabletop 24 (see Figure 1), can be rotated (in the direction F1) by the user about a horizontal longitudinal axis X, by means of the articulated retraction mechanism 26 (shown schematically in the drawings), so as to be brought in a horizontal position under the tabletop 24 - see Figure 2.
  • the extension 22 is hinged on to proper supports 28 provided on the tabletop 24 and turns thereabout - see Figure 3, direction F2 - by rotating about a substantially vertical axis Y and, hence, displacing in a horizontal plane.
  • the extension 22 should there be provided two extensions 22 (as shown by way of example in Figures 1 to 3) that, when protracted, extend on two opposite sides of the table 20, the same extensions, when retracted, will then come to lie co-planar and close to each other under the tabletop 24.
  • the corresponding, homologous sides 30 of the extensions 22 that are the farthest ones when the extensions 22 are protracted, become the closest ones when the same extensions 22 are in their retracted position (owing to the extensions 22 themselves having been turned by 180°).
  • the construction of the above-described table 20 is such as to put a constraint, i.e. restrict the maximum length that the extensions 22 can have (and, hence, the maximum length that can be reached by the table 20 itself), since each one of these extensions shall be capable of being retracted even when the other one is already in its retracted position (so that it might interfere with the first one being displaced into its retracted position).
  • a constraint i.e. restrict the maximum length that the extensions 22 can have (and, hence, the maximum length that can be reached by the table 20 itself)
  • each one of these extensions shall be capable of being retracted even when the other one is already in its retracted position (so that it might interfere with the first one being displaced into its retracted position).
  • the length of the extensions 22 is increased, the same extensions would end up by touching each other with their sides 30 when in their retracted position.
  • Such further improvement is actually the main object of the present invention, wherein such purpose is reached in a table comprising: - a raised tabletop as supported at at least two end portions thereof by corresponding supports;
  • a table 21 according to the present invention is shown schematically in Figure 4, in which (and the same applies also to the other Figures) the same reference numerals are used as in the preceding Figures to indicate same items and parts (the extensions in their protracted position are indicated with dashed lines in Figure 4).
  • spacer means compact in a protracting/retracting mechanism 136, 138
  • the possibility is given for the height of the same extensions 22 - relative to both each other and the tabletop 24 - to be offset, thereby creating an additional space enabling the length of said extensions to be further increased.
  • the spacer means determine the distance from the tabletop 24 of the horizontal plane of rotation of an extension 22, which means that this extension 22 keeps in a co-planar relation as it displaces in the horizontal plane (the fixed distance between said tabletop 24 and said horizontal plane is most suitably established either at the factory site or a first time by the user him/herself).
  • the same may therefore comprise a rotatable support hinged on to the stand 28 about the substantially vertical axis Y, to this rotatable support there being hinged about the horizontal axis X a means for an extension 22 to rest thereupon.
  • said spacer means may comprise discs having a calibrated thickness, to be arranged above and/or under the rotatable support hinged on to the stand 28. In this manner, the accurately gauged thickness of the discs sets the distance that has to be kept between an extension 22 (not necessarily all of them) and the tabletop 24 in the retracted position thereof.
  • FIG. 1 is a schematical side view of a table with protracted extensions
  • FIG. 2 is a schematical side view of the table shown in Figure 1 , with the extensions thereof in the protracted, but lowered position;
  • FIG. 3 is a schematical side view of the table shown in Figure 1 , with the extensions thereof in the retracted position;
  • FIG. 4 is a schematical side view of the table shown in Figure 1 as modified according to the innovative concept of the present invention
  • FIGS. 5 and 6 are three-quarter views of two protracting/retracting mechanisms of a table according to the present invention, in a first position thereof;
  • - Figure 7 is a three-quarter view of the protracting/retracting mechanism shown in Figure 5, in a second position thereof;
  • - Figure 8 is a top cross-sectional view of the protracting/retracting mechanism shown in Figure 5, taken along a median horizontal plane l-l in Figure 9;
  • - Figure 9 is a side view of the protracting/retracting mechanism shown in Figure 5, in the position shown there;
  • FIG. 10 is a three-quarter view of a side of the table shown in Figure 4.
  • these illustrate two protracting/retracting mechanisms 136, 138 for an extension 22 (shown in dashed lines in Figure 10 only).
  • these protracting/retracting mechanisms 136, 138 are located in the same position and arranged to perform in the same manner as the articulated joint 26 described hereinbefore.
  • the same reference numerals as in the foregoing description are used to indicate like parts and items, whereas the prefix "2" and the brackets are used to indicate like parts of the mechanism 138 that for reasons of greater simplicity are described in connection with the sole mechanism 136, but are not shown.
  • Each protracting/retracting mechanism 136, 138 comprises a respective resting member 140 (240) for an extension 22 that is capable of rotating about a horizontal axis X1 relative to a rotatable support 142 (242), thanks to a coupling pin 144 (244) integral with the support 142 (242) and accommodated into a corresponding seat 162 (262) in the resting member 140 (240) itself - see Figure 8 illustrating the protracting/retracting mechanism 136 in a horizontal cross-sectional view thereof, which is the same as the protracting/retracting mechanism 138 in this detail, and see also Figure 7 illustrating for example the resting member 140 rotated by 90° with respect to the illustration appearing in Figure 5.

  • the resting member 140 (240) comprises a side mouth 180 (280) that can surround a corresponding protrusion 182 (282) of the support 142 (242) - see Figures 7 and 9.
  • the resting member 140 (240) and the support 142 (242) are joined firmly with each other.
  • the rotatable support 142 comprises an annular portion 146 (246) that surrounds a corresponding round head 148 (248) - cf.

  • each support 142 (242) is therefore able to rotate about a substantially vertical axis Y1 relative to the fixed body formed by the base disc 150 (250) and the disc 152 (252) associated thereto.
  • the head 148 (248) of the base disc 150 (250) comprises a horizontal through- bore 166 (266), at the two ends of which there are housed two pins 168, 169 (268, 269) that are radially biased by a spring 172 (272) towards two corresponding diametrical recesses 174, 175 (274, 275) provided in the inside surface of the annular portion 146 (246).

Abstract

La présente invention concerne une table (21) composée d'un plateau de table surélevé (24) soutenu à au moins deux de ses extrémités (5) par des supports correspondants (28) et deux ou plusieurs rallonges extensibles (22), chacune d'elles étant associée à un support correspondant (28) par un mécanisme de rétraction dans le prolongement (136, 138). Ce mécanisme (136, 138) permet à la rallonge correspondante (22) de se déplacer d'une position rétractée sous le plateau (24) à une position dans le prolongement où elle trouve dans le même plan que le plateau (24), ce dit déplacement comprenant une rotation autour du support (28) et une rotation autour d'un axe horizontal (X1). Lesdites deux ou plusieurs rallonges (22), quand elles sont rétractées, sont décalées l'une par rapport à l'autre, c’est-à-dire se trouvent à une distance différente du dit plateau (24).
