Abstract
Regards a coupling and supporting device of additional
planes of an extensible table, where the additional planes
are contained below the main plane, and they are extracted
when they are to be used. Such device is characterised in
that it comprises a mechanism substantially consisting of a
pair of parallel rods, sliding into guides, applied below
the main plane of the table. Such rods - when needed - are
made to protrude from a side of the same table, usually from
the side exhibiting a smaller length, so as to form the
support of an additional plane. The main characteristic of
the device according to the finding is that each of the two
rods of each pair is provided, at its end, with a spring
leverage which provides to coupling the additional plane and
keeping it locked when it is aligned with the same main
plane.
Description
- The finding relates to a coupling and supporting device of additional planes of an extensible table, as described in the general part of
claim 1. - The so-called extensible tables are increasingly spreading in modern furnishings; when necessary, they can be coupled to one or more additional planes.
- Usually, the additional planes are contained below the main plane, and they are extracted when they are to be used.
- In the prior art there are several mechanisms realised to move and support the additional planes, consisting of sliding tracks, supporting brackets, stopping hooks, and other components with different configuration.
- However, these devices exhibit a considerable volume, and thus the table is generally provided with a side covering the above devices.
- Purpose of the present finding is that of realising a coupling and supporting device of additional planes of an extensible table, which should be easy to realise and use by the user but, above all, having a small thickness in the table height, thus eliminating the above side.
- This is realised with a mechanism substantially consisting of a pair of parallel rods, sliding into guides, applied below the main plane of the table, which - when needed - are made to protrude from a side of the same table, usually from the side exhibiting a smaller length, so as to form the support of an additional plane.
- Each of the two rods of each pair is provided, at its end, with a spring leverage which provides to coupling the additional plane and keeping it locked when it is aligned with the same main plane.
- The pair of sliding rods supports a cup serving as container for the additional plane, when it is not used.
- The features of the finding will appear more clearly from the description of a possible embodiment, made only by way of an illustrative and non-limiting example, with reference to the attached drawings. In such drawings:
- Fig. 1 (Table I) shows the perspective view of a table provided with the device of the finding, in opening condition;
- Fig. 2 (Table II) shows the perspective view of the table of Fig. 1, with the device in closing condition;
- Fig. 3 (Table III) shows a front sectioned view, according to line III-III of Fig. 2, of the table with the device in closing condition;
- Fig. 4 shows a front sectioned view, according to line IV-IV of Fig. 1, with the device in opening condition;
- Fig. 5 (Table IV) shows a detailed front view of the leverage in uncoupling condition;
- Fig. 6 shows a detailed front view of the leverage in coupling condition;
- Fig. 7 shows a plan sectioned view, according to line VII-VII of Fig. 6;
- Fig. 8 (Table V) shows a construction perspective view of the device of the finding;
- Fig. 9 (Table VI) shows a construction perspective view of the leverage;
- Fig. 10 (Table VII) shows a construction perspective view of the device of the finding, provided with the cups and with an additional plane.
- As it can be seen in figures 1 and 2,
device 1 of the finding, applied below the supportingplane 2 of the table and intended to support the twoadditional side planes 3, consists of two pairs ofrods 4, sliding intoguides 5 applied below theabove plane 2. - A
cup 6 is applied on each pair of rods, so as to contain theadditional plane 3 when the table is "closed" (reference shall be made to fig. 2). - The device is characterised by the system for coupling and locking the
additional plane 3, when it is aligned with the supportingplane 2, which comprises aleverage 7, actuated by the user. - As it can be seen in figure 3 and following ones,
leverage 7 consists of asmall base 8, idly pivoted onpin 9 integral withrod 4 and provided with atooth 10 which, in working position, couples withstrap 11, applied on theadditional plane 3, thus realising the desired locking. - The rotation of the
small base 8 onpin 9 to allow the coupling/releasing action, occurs through thelever arm 12, pivoted onpin 13, integral with thesmall base 8 and engaged with thelozenge slit 14 on the guidingpin 15, anchored torod 4. - The crank gear thus realised is made elastic through the
shaped spring 16, constrained at the two ends, respectively to the twopins lever arm 12, locks the leverage in the two end positions, as it can be seen in figures 5 and 6. -
Leverages 7, applied into the tworods 4, are reciprocally connected throughcrosspiece 17, which makes the twolever arms 12 reciprocally integral and forms the gripping handle for the operator. - Operatively, when the table is "closed", as it can be seen in figures 2 and 3, where the two additional planes 3' and 3'' are contained into the
respective cups 6 and arranged substantially overlapping, the operator provides to manually extract the entire mobile carriage so as to withdraw the above additional planes and arrange them above the pair ofrods 4, which protrude from themain plane 2. - Then, the operator provides to manually
lower crosspiece 17, so as to allow the support of theadditional planes 3 on the protruding pairs ofrods 4 and afterwards, he provides to lifting the above crosspiece again so that, with the rotation of thesmall base 8,tooth 10 couples onstrap 11 of the additional plane. - Of course, other embodiments are possible besides that illustrated, according to the table size or for the use of specific accessories and construction elements, without departing from the scope of the claims defined below.
