Definitions

  • the present invention relates to an extension table (s) of the type comprising a main plate, at least one movable extension and a motorized drive mechanism of the extension between a storage position under the main plate and a position of use next to and in the plane of this plateau.
  • the same motorized mechanism ensures the reverse movement of the extension.
  • the device of this prior document has various disadvantages: it has many moving parts with uncertain guides and implies that the two extensions are raised at the same time. In addition to the open position, because of the games necessary for their vertical rise along the shelf, the extensions are slightly mobile because not tight against the edges of the fixed tray, which can be inconvenient for users of the table. In addition, such a system is complex in construction and therefore very expensive.
  • the invention aims to achieve a table equipped with at least one extension and not having these disadvantages.
  • the extender table (s) targeted by the invention comprises a frame attached to the legs of the table, a main tray and at least one extension and a motorized drive mechanism of the extension between a storage position under the tray main and a position of use beside and in the plane of this plateau.
  • the drive mechanism allows, with the aid of the single movement of linear motorization, on the one hand to ensure the horizontal movements of the extension for its output or storage under the horizontal plate, then to ensure the movements of gradual rise of the extension to the level of the plane of the main plateau or descent for storage.
  • this mechanism makes it possible to tighten at the end of the opening stroke the extension against this plate, in order to obtain a position of the open extension very stable and without play with respect to the main plate.
  • the motor can be an electric linear cylinder, pneumatic or hydraulic or any other equivalent drive member.
  • the table provided with the drive mechanism according to the invention is of relatively simple structure and therefore inexpensive. Its operation is reliable and its easy and effortless use, with an advantageous tightening of the extensions in open position against the main plate which gives them great stability.
  • the table according to the invention is of great flexibility of use because according to the embodiment, the mechanism can be used to drive either one or both extensions, or both extensions simultaneously.
  • Figure 1 is a top plan view of a first embodiment of the table according to the invention, comprising two extensions arranged under the main plate in the non-use position.
  • Figure 2 is a cross-sectional view along 2--2 of Figure 1.
  • Figure 3 is a partial perspective view from below of the table of Figures 1 and 2 with a single extension shown during a horizontal translation phase.
  • Figure 4 is a partial perspective view from below showing two of the legs of the table and illustrating the rise or fall of an extension.
  • Figure 5 is a bottom plan view of the table of Figures 1 to 4 with the two extensions exits and in the plane of the plate.
  • Figure 6 is a longitudinal sectional view along 6 - 6 of Figure 5.
  • Figure 7 is a partial perspective view from below of a second embodiment of the table according to the invention, showing one of the extensions in the rising phase or descent.
  • Figure 8 is a partial perspective view from below of a third embodiment of the table according to the invention.
  • the table T comprises a main plate 1 fixed on a frame 8 equipped with support feet on a horizontal plane.
  • the frame 8 consists of two longitudinal walls 22 and two transverse bars 10, 21 for connecting the walls 22.
  • the table T comprises two extensions 5 which can extend the plate 1 at its opposite ends, and two similar mechanisms for driving a respective extension 5 (only one of which is shown in FIGS. 3 and 4 for reasons of simplification) between a position storage under the main tray 1 ( Figures 1 and 2) and a position of use against and in the plane of this tray (Figs 5 and 6).
  • Each drive mechanism comprises a linear actuator 2 driving the corresponding extension 5 from its storage position to its use position and vice versa.
  • This motor 2 may be advantageously for its irreversibility a linear electric cylinder provided with a body 2a and a movable portion constituted by a rod 2b, or a pneumatic cylinder, or hydraulic or any other equivalent equivalent drive member.
  • the body 2a is articulated by a pivot connection 11 with the crossbar 21 of the frame 8.
  • the movable rod 2b is articulated by a pivot connection 12 with a lever 3, itself pivotally connected 14 in its middle part with a transverse bar 23 of a carriage 4 supporting the associated extension 5.
  • the lever 3 is in pivot connection 7 with a transverse bar 24 of the extension 5.
  • the two transverse bars 23, 24 are connected at their ends by hinged rods 9.
  • the pivot links 12, 14, 7 are arranged in the central part of the bars 23, 24.
  • the carriage 4 also comprises two longitudinal bars 25 parallel to each other. .
  • the extension 5 comprises two rails 26 parallel to each other, to which is fixed the plate of the extension and arranged above the bars 25.
  • Two transverse bars 27, 28 parallel to the bars 23, 24 connect the ends of the bars longitudinal members 25 and longitudinal members 26 opposite the lever 3.
  • Two other rods 9 are articulated on the ends of the bars 25, longitudinal members 26 and transverse bars 27, 28.
  • the two pairs of rods 9 are articulated on the opposite ends of the bars. 25 and longitudinal members 26.
  • the four links 9, the two bars 25 and the four transverse bars 23, 24, 27, 28 thus form a double parallelogram articulated between the carriage 4 and the extension 5, which can thus be raised or lowered by a movement of circular translation with respect to the carriage.
  • the longitudinal bars 25 of the carriage 4 are guided in horizontal translation by respective parallel rails 6 connected to the frame 8 by attachment to the inner faces of the longitudinal walls 22 of this frame.
  • the drive mechanism also comprises a mechanical stop 10 connected to the fixed frame 8, against which the lever 3 can dock and be stopped at the end of horizontal translation travel and then be supported for its recovery during the rise phase of the extension.
  • the abutment 10 is formed by a transverse bar connecting the walls 22 of the frame 8 in the vicinity of the edge of the plate 1 contiguous to the associated extension 5.
  • the abutment 10, the transverse bar 21 and the longitudinal walls 22 define the fixed frame 8 secured with the underside of the tray 1 and with the legs 18 of the table T.
  • Each extension 5 is thus associated with a drive mechanism such as that just described (FIGS. 1, 2, 3, 4, 5 and 6).
  • the control of the electric cylinder 2 pulls the movable rod 2b on the lower end of the lever 3, which tilts around its hinge 14 and begins to tilt horizontally.
  • the extension 5 being in abutment against the edge of the main plate 1 can not move horizontally.
  • the drive mechanism differs from the previous embodiment in that it includes a mechanical stop 16 connected to one of the crosspieces 13 fixed at their ends to the two walls 22 of the fixed frame 8.
  • the stop 16 is arranged to act directly on the crossbar 23 of the corresponding carriage 4.
  • the body 2a of the cylinder 2 is in fixed connection with the trunk 8 through the cross members 13 to which it is attached.
  • a connecting rod 15 is interposed between the end of the movable rod 2b of the cylinder 2 and the lower end of the lever 3 and pivotally connected to these two ends.
  • the intermediate rod 15 therefore transmits to the lever 3 the movement of the rod 2b by tilting during the rising phase of the extension 5 while the lever 3 recovers to the vertical.
  • the operation of the mechanism is also similar to that of the embodiment of Figures 1 to 6.
  • the table comprises a single extension 5 and a single linear jack 2, whose body 2a is pivotally connected 11 with the main plate 1 itself movable in horizontal translation relative to the frame 8.
  • This articulated connection 11 is arranged on a transverse bar 29 connecting two wings 30 of the plate 1.
  • the end of the rod 2b is connected to the extension 5 via the lever 3.
  • the plate 1 is movable only in horizontal translation relative to the fixed frame 8 (integral with the legs of the table not shown) between two stops 17 , thanks to the slides 6 fixed on the inner faces of the walls 22 and on which can slide the wings 30 of the main plate 1.
  • the position of the plate 1 relative to the frame 8 can thus be controlled by the cylinder 2 acting on the lever 3 and on the mobile plate 1 by action and reaction.
  • the rod 2b of the ram 2 continuing its movement then actuates the lever 3 the carriage 4 and the extension 5.
  • the operation of the drive mechanism of the extension 5 allows the translations and the raising, lowering and clamping movements of the extension 5 in a manner identical to the previous embodiments.
  • extension lever 3 can be replaced by a cam lever articulated on the cylinder and the carriage and whose cam bears under the extension.
  • the table may be provided with a single extension 5 ( Figure 8) or two extensions 5 ( Figures 1 to 7) each equipped with an independent drive mechanism which allows to maneuver separately and gives greater flexibility of use at the table.
  • the table provided with the extension drive mechanism (s) according to the invention has a relatively inexpensive and therefore inexpensive structure. Reliable and very flexible and easy to use thanks to the motorized extension system, it brings the comfort of a great stability of open extensions.
