• the removable support according to the invention is for example intended to support accessories of a worktop 1.
• the removable support comprises mounting means on an edge of the worktop 1. These mounting means make it possible to obtain a stable and rigid positioning to support accessories such as computer screen, television or other.
• the removable support comprises locking / unlocking means making it possible to move and position said support in a stable manner on the edge of the work surface 1.
• the locking / unlocking means comprise a gripping member 2 intended to extend above the work surface 1. The gripping member 2 is therefore easily accessible for the user in a sitting or standing position relative to the plane 1.
• the removable support comprises a lower jaw 3 extending at least partially under the work surface 1.
• the lower jaw 3 thanks to a support plate 3a, allows the removable support to bear on the underside of the work plan 1.
• the support removable further comprises an upper jaw 4 bearing on the work surface 1 through another support plate 4a.
• the upper jaw 4 allows the removable support to bear on the upper face of the worktop 1 and supports the weight of the molded accessory on the worktop 1.
• the removable support also includes an actuating mechanism associated with the gripping member 2, ensuring the relative tightening and loosening of the lower 3 and upper jaws 4.
• the actuating mechanism thus makes it possible to enclose the work surface 1 between the lower 3 and upper jaws 4 with manipulation of the gripping member 2, controlling the relative movements of said jaws 3 and 4.
• the actuation mechanism comprises a link arm 5 integral with the lower jaw 3 and extending substantially orthogonally to the support plate 3a.
• the link arm 5 also has a threaded upper part 6.
• the threaded upper part 6 extends above the work surface 1, thus making it easily accessible.
• the actuating mechanism also comprises an opening 7 of shape complementary to the threaded upper part 6 and formed in the other support plate 4a.
• the opening 7 can thus be traversed by the threaded upper part 6 projecting above the work surface 1.
• the opening 7 opens onto a hollow cylinder 8, itself extended by a tube 9 of reduced diameter compared to to the hollow cylinder 8.
• the latter is integral with the upper jaw 4 and the tube 9. It is on this tube 9 that the accessories are engaged.
• the actuating mechanism also comprises longitudinal windows 10, formed in the hollow cylinder 8 starting from the opening 7.
• the threaded upper part 6 thus engages and moves in the hollow cylinder 8 with thread portions 6a making protruding from the longitudinal windows 10.
• the gripping member 2 is advantageously a sleeve engaged on the hollow cylinder 8 and having a thread 11, shown for example in the Figure 7.
• the internal thread 11 engages with the thread portions 6a.
• the threaded upper part 6 comprises three branches 12a, 12b, 12c in the extension of the link arm 5 These three branches 12a, 12b, 12c are arranged relative to each other in a determined angular orientation identical to the angular orientation presented by the longitudinal windows 10 formed in the hollow cylinder 8.
• the threaded upper part 6 has for example a substantially V shape in a cross section of which each apex is provided with a thread portion 6a longitudinal .
• the threading portions 6a extend longitudinally over a length less than that of the longitudinal windows 10 thus allowing sliding in the hollow cylinder 8.
• the longitudinal dimensions of the link arm 5 are chosen to allow movement of the lower jaw 3 by relative to the work surface 1, the edge of which extends between the support plates 3a and 4a.
• the end of the hollow cylinder 8 from which the tube 9 extends comprises, on a peripheral zone 13, a stop lug 14.
• the removable support according to an exemplary embodiment comprises a safety device preventing the separation of the lower 3 and upper jaws 4 of the work plan 1 during the movement of said support.
• the safety device comprises for example a rod 16 secured to the lower jaw 3 and having a bent end 17 cooperating with a stop of the work surface 1.
• the stop is for example a groove 18 formed in the lower face of the work surface 1.
• the stop is a part 19 substantially L-shaped, fixed under the work surface 1.
• the rod 16 is integral with a profile 20 with rectangular section fixed for example by means of screws 21 on the support plate 3a.
• This profile 20 advantageously has the same thickness dimensions as the work surface 1 and also provides additional support for the plate 4a.
• the lower 3 and upper 4 jaws therefore bear on a rigid support on either side of the link arm 5, contributing to the mounting stability of the removable support.
• the profile 20 is simply enclosed between the lower jaws 3 and upper 4 and is not associated with any other means of attachment to said lower jaw 3.
• the safety devices are replaced by a fixed profile 22 secured to the work surface 1.
• This fixed profile 22 is fixed by any means on the work surface 1 and has a given distance with respect to the latter making it possible to make a slot 23 of introduction for the lower jaw 3.
• the removable support comprises pads 24 made of Teflon® fixed on the upper jaw 4 and providing the interface with the work surface 1. It is thus possible to slide with great ease the removable support on the work surface 1.
• the accessory intended to be mounted on the removable support, according to the invention is preferably provided with a mounting member, not shown, engaging in or on the tube 9.
• the engagement member is a hollow tube not shown, the end of which rests on the upper end 8a of the hollow cylinder 8.
• the p as thread portions 6a is chosen to generate with a rotation, for example of a quarter turn of the gripping member 2, a displacement sufficient of the lower jaw 3, allowing the sliding of the removable support on the work surface 1.
• the movement of the lower jaw 3, corresponding to the release is delimited by the arrival in abutment of the support lug 15 on the stop lug 14.
• the pitch of the threading portions 6a is adapted to the thickness, generally standard of the work surfaces 1.
• the dimensions of the bent end 17, of the groove 18 or of the part 19 are also chosen to avoid a relative disengagement following the unlocking, that is to say the downward movement of the lower jaw 3, corresponding to the rotation of the gripping member 2 arriving in abutment.
• any disengagement between the removable support and the work surface 1 is thus prevented during its sliding on said work surface 1.
• the user can thus move any accessory on a work surface with great safety, in the absence of a fixed profile 22.
• Another advantage of the removable support according to the invention lies in the fact that any manipulation relating thereto is reduced to the rotation of the gripping member 2 over a fraction of a turn.
• Another advantage of the removable support according to the invention lies in the positioning of the clamping axis lower 3 and upper jaws 4. This axis is offset towards the inside of the work surface 1 and this thanks to the conformation of the branches 12a, 12b, 12c, and in particular thanks to the overhanging position of the branch 12c with respect to on the work surface 1. A more efficient tightening and a more stable positioning of the removable support is thus obtained on the work surface 1.
• Another advantage linked to the removable support according to the invention lies in the concentric mounting of the c hollow ylindre 8 of the tube 9 and the gripping member 2. This gives a reduced number of parts, a small footprint and a remarkable aesthetic quality.
