Definitions

  • the present invention refers to an extensible table, such as for instance a dining table having, further to a fixed worktop, at least one extension.
  • An extensible table is known, for example from the disclosure in EP-A-0857483, which is provided with a single arcuate guide, arranged according to the longitudinal centre-line plane thereof, acting as a structure supporting both the fixed central worktop of the table and the four legs thereof. Inside the axial cavity of such a guide there are associated telescopically a first and a second plate, to the end portions of which there are attached, on the lower side thereof, the two extensions by means of controlled-motion hinge-like members.
  • This kind of extensible table has a drawback in that, owing to the considerable length of the path of the plates onto the guide and the condition of sliding friction between contact surfaces, there may happen that the extensions get stuck during pulling out or retracting. Furthermore, it should be duly considered that the extensions are only in contact with the borders of the fixed worktop, so that they have practically no possibility at all for them to be able to at least partly discharge on to said fixed worktop itself the stresses that are imparted to the same extensions during use.
  • a further aim of the present invention is to improve the comfortableness of the people sitting around the table, regardless of the extensions being pulled out or retracted.
  • Another aim is to ensure that the extensions are prevented from being unintentionally moved with respect to the fixed worktop, in particular when the extensions and the worktop are made with thick crystal panes and consequently particularly heavy as well as fragile.
  • FIG. 1 is a side view of a rectangular extensible table according to the present invention, in which a first extension is shown when retracted state and a second extension is shown when pulled out;
  • FIG. 2 is a top, partially see-through view of solely a half (for reasons of greater simplicity) of the same table in the extracted-extension configuration thereof;
  • - Figure 3 is a sectional view on an enlarged scale along the line A-A of Figure 1, showing the linking means between the fixed central worktop of the table and an extension thereof, when the latter is retracted;
  • - Figure 4 is a sectional view similar to the one appearing in Figure 3, however along the line B-B of Figure 1 and showing said linking means when the extension is when the extension is pulled out;
  • FIG. 5 is an exploded view of alternative means for linking a fixed worktop made with a relatively thick crystal pane with an extension of the same type;
  • FIG. 6 is a schematic top view of another embodiment of the invention.
  • a table according to the present invention comprises a fixed central worktop 10 (made preferably of wood) with a rectangular shape which, starting from the top surface 11 (ie. the surface that is exposed to view), is cut on the short sides 12 thereof according to the section planes 13 which, instead of being perpendicular to said surface 11, as this is the case in the great majority of prior-art tables, are inclined with respect thereto by an acute angle ⁇ of indicatively 15 to 20 degrees, as this is best shown in Figure 3.
  • the lower (ie. not exposed to view) surface 14 of the fixed worktop 10 of the table is shorter than the top surface 11 exposed to view.
  • each one of said short sides 12 to the fixed worktop 10 there is associated an extension 30 which, when retracted, extends underneath the fixed worktop 10, as illustrated on the left side of Figure 1 as well as on Figure 3.
  • the extension 30 is cut, starting from the side 31 thereof (which is parallel and adjacent to the short side 12 of the fixed worktop 10), according to a section plane 32 which is also inclined by the same afore cited acute angle o with respect to the surface 33 that faces the floor S when the extension is retracted.
  • the surface of the extension 30 lying on the opposite side of the above mentioned floor-facing surface 33, ie. the surface that remains exposed to view when the extension 30 is extracted as shown in Figure 4, is generally indicated at 34.
  • the portion of the extension 30 has a substantially rectangular shape in correspondence of the inclined section plane 32 while the portion 37, which is adapted to protrude from the short side 12 of the fixed worktop 10 is of a substantially semi-circular shape.
  • the linking means provided between the fixed worktop 10 and the extension 30 to enable the latter to be pulled out and which are generally indicated at 20 in the Figures, are arranged along the longitudinal centre-line plane P of the table and, as illustrated in Figures 2 and 4, consist of:
  • first rigid plate 21 attached to the worktop 10 (using traditional means that are not shown in the Figures, such as for example dowel-pins distributed along the perimeter thereof, or the like) in such a manner as to lie flush with, ie. on the same level as the inclined section plane 13, with the exception of a threaded stud 22 that is welded at the centre of the same plate in such a manner as to protrude downwards along an axis Z that is perpendicular to the plane 13.
  • a recess 35 which is provided in the thickness of the extension 30 starting from the surface 33 thereof, accommodates the stud 22;
  • a second rigid plate 23 that is similar to said first rigid plate 21 and is attached to the extension 30 in such a manner as to lie flush with, ie. on the same level as the inclined section plane 32, with the exception of a cylindrical bushing 24 that is welded at the centre of the same plate 23 so as to in turn protrude downwards into said recess 35, thereby being capable to accommodate in its interior said threaded stud 22, which it is coaxial with;
  • a third plate 25 made of an antifriction material such as PTFE, or polytetrafluoroethylene, and featuring a minimum thickness, which is perforated centrally and is arranged between the adjacent surfaces of the rigid plates 21 and 23, where it is firmly retained by tightening a nut 26 on the protruding portion of the threaded stud 22 until it is brought into abutment against the end portion of the bushing 24 (which is therefore provided with correspondingly appropriate inside diameter, outside diameter and length).
  • PTFE polytetrafluoroethylene
  • the common axis Z to both the threaded stud 22 and the bushing 24, perpendicular to the inclined section planes 13 and 32, is the axis about which - through a movement having an amplitude of 180 degrees - the extension 30 is caused to rotate with respect to the fixed worktop 10 in order to change from its retracted configuration to its extracted configuration, and vice- versa.
  • this rotation which can be carried out most easily and conveniently by the user without any need arising for any considerable free space to be available around the table, is the sole and only handling required for switching from a configuration to the other one.
  • the table may also be provided, in the proximity of the linking means 20, with a retaining device (not shown) adapted to ensure that a retraction of the table may only occur on purpose, and not accidentally.
  • a further feature of the present invention is given by the legs of the table, which are each of them consisting of a tubular body 40, for instance of a circular cross-section, that is attached to a rigid support 41 arranged.
  • the arms 42 and 43 of the rigid support 41 are both substantially rectangular in their cross-section.
  • the body 40 of the leg is attached to the free end 44 of the arm 43 along an axis Y perpendicular thereto, ie. inclined with respect to the floor S, for instance by means of a threaded stud 45 extending along the same axis Y - see Figure 1.
  • a cylindrical metal bushing 100 delimited between the ends 105, 107 which are perpendicular to its axis.
  • a sloping wing 102 where three threaded holes 103, arranged in a triangular layout, are provided, is attached to the bushing so as to protrude therefrom.
  • a pair of axial grooves 104, 106 which have a semicircular cross-section and are spaced 180° from one another, are internally provided in the bushing 110.
  • a round groove which also has a semicircular cross-section - such as the one shown in Figure 5 under reference numeral 108 - is provided at each of the said ends 105, 107. The purposes of the said grooves are clarified here below;
  • first round disc 110 consisting of a first flat portion 112 and a second portion 114 of a smaller diameter in which are provided four axial threaded holes 116 and a transversal groove 118 of a semicircular cross-section.
  • An annular channel 119 of a semicircular cross-section is provided onto the face 113 of said first flat portion 112 looking at said second portion 114 of the disc 110;
  • a second round disc 120 having a lower flat base 122 and an upper base which consists of a first flat portion 124 and a second sloping portion 126.
  • the flat base 122 there are : four axial threaded blind holes identical to the holes 116, a transversal groove of a semicircular cross-section identical to the transversal groove 118 and an annular channel of a semicircular cross-section identical to the channel 119 of the first disc 110;
  • a third round and flat disc 130 having a smooth upper base 132 and a lower base provided with three threaded holes (not visible) matching with the holes 103 provided onto the wing 102 of the bushing 100;
  • a spring 140 biasing a couple of pegs 142, 144 having round heads which match with the above mentioned axial grooves 104, 106 in the bushing 100 so as to be retained by the latter and partially retained in the groove 118 of the first disc 110.
  • the bushing 100 is sandwiched between the first disc 110 at the bottom and the second disc 120 at the top which are rigidly joined to one another through four bolts (not shown) screwed on the threaded holes 116 in the smaller portion 114 of the first disc 110 and the corresponding blind holes provided on the flat base 122 of the second disc 120.
  • the legs of the bolts do obviously not interfere with the spring 140 subsequent to the insertion of the latter in the cavity formed by the matching transversal groove 118 of the bushing 110 and the matching groove of the second disc 120.
  • a series of antifriction balls (not shown) are arranged in the round channel 108 at the base 107 of the bushing 100 and the corresponding channel on the flat base 122 of the the disc 120 while another series of balls are arranged in the round channel 119 of the disc 110 and the corresponding channel on the second base 105 of the bushing 100.
  • the third disc 130 is in turn secured to the wing 102 through three bolts (not shown) screwed on the threaded holes 103 and the corresponding holes provided on its lower base.
  • the linking means are connected as follows to the table.
  • the first flat portion 124 of the upper base of the second disc 120 is firmly attached (preferably by means of a transparent adhesive layer) to the lower surface - ie the surface that would not be exposed to view if it were made with a non transparent material - of the fixed worktop and the second sloping portion 126 to the adjacent inclined section plane of the same worktop through.
  • the extension when in the retracted configuration the extension lies below the fixed worktop with the inclination of the sloped wing 102 so as to neither interfere with the fixed worktop nor with the legs of the table.
  • the extension - integrally with the third disc 130 - can be brought into its extracted configuration.
  • the extracted extension can obviously at ant time be brought back to its retracted configuration by a rotational movement of the same amplitude in the opposite direction of the bushing 100.
  • the spring 140 - which, as already mentioned, subsequent to assembly of the linking means is retained between the transversal groove 118 of the first disc 110 and the corresponding groove at the lower base 122 of the second disc - has the purpose of ensuring the due stability of the extension in the retracted as well in the extracted configuration.
  • the peg 142 fits in the groove 104 and the peg 144 fits in the groove 102 while, when the extension 160 is extracted, the peg 142 fits in the groove 102 and the peg 144 fits in the groove 104.
  • the table of the embodiment schematically shown in Figure 6 has a fixed worktop 150 with four identical sides 152 from which four identical extensions 154 are adaped to protrude thanks to associated linking means 158, which - although diagrammatically shown - are are of any of the above described constructions.
  • the protruding portions 155 of the extensions 154 are in the shape of a circular segment, in such a way that the table is adapted to be easily converted from a square shape when the extensions are in their retracted configuration (shown in dotted lines in Figure 6) to a round shape when all of the four extensions are pulled out (shown in full lines).
