Abstract
Description
- The present invention refers to an expandable connector for a leg with an adaptable attachment to a work surface, particularly but not exclusively for table production.
- As is well known to experts of the sector, to reduce encumbrance and the risk of damage during storage and transportation, legs are preferably assembled to the work surface at the time of final installation where the user wants it.
- Moreover, in the sector of table production there is a strong need to realise the surfaces themselves so that they can be disassembled into many distinct parts which can be connected together at a later point in time in a stable and practical manner.
- For example, the realisation of tables for workplaces in particular requires a high flexibility of configurations of the work surface, to combine maximum functionality with the aesthetic aspect.
- The need to cut production costs, whilst still offering the client a vast range of solutions has led to the development of modular structures, which foresee the variable combination of surfaces with a determined number of standardised shapes.
- To standardise the assembly instruments and the tools needed to put together tables or support structures, to benefit both producers and users, multifunctional connectors have also been developed. Multifunctional connectors can be used both to connect the legs of tables to surfaces or to structures and to join two surfaces together.
- Connectors can possibly be dismountable to allow the at least partial reuse of the individual elements in the realisation of new configurations of tables or of support structures, or more simply to allow the subsequent storage thereof.
- Connectors for legs must first of all guarantee a connection which is stable through time to obtain a table or a structure which is solid without the risk of deterioration of the materials used.
- Indeed, resistance to stresses, for example deriving from lifting or sliding, must be guaranteed.
- Moreover, it is desirable that connectors for legs also allow end users to rapidly carry out connections with the help of common tools, such as a screwdriver or an Allen key.
- Dismountable connectors which are currently available do not allow all of the listed factors to be optimised. Above all they have great difficulty in combining simplicity of construction and use with the requirements of strength, in any case losing out on the aesthetic aspect.
- The general purpose of the present invention is that of overcoming the aforementioned drawbacks of the prior art in an extremely cost-effective, simple and particularly functional manner.
- Another purpose is that of realising an expandable connector for a leg with an adaptable attachment to a work surface which achieves an excellent aesthetic result.
- In view of the aforementioned purposes, according to the present invention, it has been thought of to realise an expandable connector for a leg with an adaptable attachment to a work surface, having the characteristics outlined in the attached claims.
- The structural and functional characteristics of the present invention and its advantages compared to the prior art shall become even clearer from an examination of the following description, referring to the attached drawings, which show an expandable connector for a leg with an adaptable attachment to a work surface, realised according to the innovative principles of the invention itself.
- In the drawings:
- figure 1 shows a plan view of a first embodiment of an expandable connector for a leg with an adaptable attachment to a work surface, object of the present invention, mounted at a corner of a surface;
- figure 2 is a section view of figure 1, according to the line II-II;
- figure 3 is a plan view of the connector of figure 1 shown with the expandable body removed and mounted as a joint between two surfaces;
- figure 4 is a section view of the connector of figure 3 realised at the middle point;
- figure 5 is a perspective view of an expandable body equipped with a manoeuvring pin
- figure 6 is a plan view of the expandable body of figure 5, partially sectioned to show a threaded seat of the manoeuvring pin;
- figure 7 is a section view of figure 6 according to the line VII-VII;
- figures 8 and 9 schematically show the deformation action caused by the manoeuvring pin on the expandable body;
- figures 10 and 11 are, respectively, plan and section views of a second embodiment of an expandable connector for a leg mounted built into the surface and shown with the expandable body removed;
- figure 12 is a plan view of a further embodiment of an expandable connector for a leg with a sleeve having a squared section shown with the expandable body removed;
- figures 13-16 are, respectively, perspective and section views of an expandable connector for a leg with an adaptable attachment for mounting to structures of tubular profiles;
- figure 17 is a section view of a last embodiment of a connector into which the end of the leg containing the expandable body is inserted;
- figure 18 is a perspective view of the hollow tubular leg of figure 17;
- figure 19 is a section view which schematically shows the deformation action caused by the expandable body on the leg in the connector according to the embodiment of figure 17;
- With reference to the drawings, an expandable connector for a leg with an adaptable attachment to a work surface, and in particular to a table surface in object is wholly indicated with 10. In the illustrated examples, according to the present invention, the
expandable connector 10 comprises asleeve 12 for interaction with aleg 13,which extends from anattachment 14 in a perpendicular direction with respect to the attachment itself and into which anexpandable body 15 is inserted. - The
expandable body 15, shown in detail in figures 5-9 comprises anouter wall 16, for example cylindrical, equipped with a portion which is easy to deform, which in the figures consists of anotch 17 extending for the whole height of saidouter wall 16. Such anotch 17 can be realised in theouter wall 16 according to generic inclinations or can be replaced by another element which gives the wall elasticity. - The
expandable body 15 is moreover equipped with a threadedseat 18 for amanoeuvring pin 19 through which the expansion is realised, according to that which is shown schematically in figures 8 and 9. - The
manoeuvring pin 19 at one end has ahexagonal seat 20 for the intervention of atool 21 and at the point terminates with a frustum-of-cone guide surface 22. - Near to the notch the expandable body has guide
surfaces 23 of the deformation to a shape which matches the frustum-of-cone surface 22 of themanoeuvring pin 19. - The
expandable body 15, in the proposed embodiments can be used in combination withconnectors 10 of different types and characteristics, some embodiments of which shall be described hereafter. - The
sleeve 12 and theleg 13 can in turn be inserted into each other in a coupling, according to two different ways of operating. - In figures 1-4 an
expandable connector 10 is shown which can be used only for the connection of theleg 13 to awork surface 24 or else also as a joint betweenindividual parts 24a and 24b of the surface. - Indeed, in such
expandable connectors 10 the adaptable attachment to awork surface 14 consists of a triangular-shaped plate 14', upon the sides of whichholes 25 are realised, according to a design which allows it to be used in both of the represented assembly situations, given that thework surfaces 24 are equipped at the corners with multifunctional standard prepunching. - The
sleeve 12 has a substantially cylindricalinner surface 26 for coupling with theexpandable body 15 and anouter surface 27, also substantially cylindrical and which can be coupled withtubular legs 13 having a matching cross-section. - The
sleeve 12 is also equipped withnotches 28 parallel to anaxis 29 of thesleeve 12 itself, and more precisely two partial notches 28' and two notches extending for the whole height of the sleeve 28'', arranged facing one another in pairs in diametrically opposite positions. - The extended notches 28'' give the
sleeve 12 the necessary elasticity to be forced against the inner surface of theleg 13, as shown for example in figure 2. The partial notches 28' as well as contributing to giving elasticity, above all allow thetool 21 to access themanoeuvring pin 19. For aesthetic reasons access to thepin 19 is always carried out from a zone hidden from view when the table is assembled, as shown in figures 1 and 3. - The
tubular leg 13, having an inner diameter such as to fitted onto thesleeve 12, is equipped with a hole, not shown, for the intervention of thetool 21 from the outside. - In figures 10-12
expandable connectors 10 for mounting a tubular leg to a work surface are shown, where the adaptable attachment to the surface consists of a punched plate 14'' of a small size, for example L-shaped, which can be mounted flush with the surface in aseat 31 formed here. - In these embodiments of the
expandable connector 10 thesleeve 12 is preferably closed by abase wall 32 equipped with a plurality ofholes 33 for attachment to thework surface 24 through screws. - The
sleeves 12 can have a circular cross-section just as they can for example have a square section (figures 10 and 12). - Finally, the
adaptable attachment 14 to a table surface can consist of anexpansion tang 114 for jointing totubular profiles 34, which constitute a frame support structure for thework surface 24. Figures 13-16 showexpandable connectors 10 which form a terminal element of the frame support structure which can be of different shapes. - In figure 13 the
attachment 14, partially in view, allows the attachment of thelegs 13 in a protruding position with respect to thesurface 24. - The described embodiments of the
expandable connector 10, refer tosleeves 12 inserted and forced by expansion inside the hollow end of thetubular legs 13. - In other embodiments, only one example of which is shown in figure 17, it is the
leg 13 which is forced by expansion inside thesleeve 12, according to that which is schematised in figure 19. - The
tubular leg 13 is equipped with anelongated notch 35 which extends above and below with respect to the hole for the key to pass (figure 18). Thenotch 35 constitutes a zone which is easy to deform which favours the forcing of theleg 13 under the action of theexpandable body 15, as schematised in figure 19. - The
sleeve 12 against which theleg 13 is forced must be solely equipped with ahole 36 for the intervention of thetool 21. - The expandable connectors for a
leg 10 with an adaptable attachment to a work surface are preferably made out of die-cast aluminium. - To connect a
leg 13 to asurface 24 for example of a table theexpandable body 15 is inserted into the sleeve 12 (figure 2) or else into the leg 13 (figure 17), taking care to make themanoeuvring pin 19 fit into thenotches 28 and theholes 36 arranged for intervention by thetool 21. - In rest position, shown in figure 8, the
manoeuvring pin 28 is already positioned in the threadedseat 18 of theexpandable body 15. By further screwing thepin 19 into the threadedseat 18 through thetool 21 the progressive engagement between the additional guide surfaces of the point of thepin 22 and of thewall 23 near to thenotch 17 is caused. Theouter wall 16 of the expandable body is therefore deformed until it reaches a circumferential size (figure 9) which takes it to couple by interference with the tubular element with a matching shape which receives theexpandable body 15, in other words thesleeve 12 or theleg 13, according to the embodiments of theconnector 10 described previously. - From that which is described above with reference to the figures, it is clear how an expandable connector for a leg with an adaptable attachment to a work surface, in particular to a table surface according to the invention is particularly useful and advantageous. The purpose mentioned in the preamble of the description is thus achieved.
- An expandable connector for a leg, object of the present invention is indeed advantageously realised through simple shapes, which allow fast treatment cycles to be carried out.
- An expandable connector, according to the preferred embodiment with a base wall, also ensures excellent rigidity which is particularly useful in jointing many pieces to form the work surface.
- Moreover, the outer appearance is not at all penalised by the possible assembly configurations.
- Of course, the forms of the expandable connector for a leg with an adaptable attachment to a table surface, object of the present invention, can be different from the one shown just as a non-limiting example in the drawings, just as the materials can also be different.
- The scope of protection of the invention is therefore defined by the attached claims.
