Definitions

  • the present invention relates to a device for removable interconnection to a surface.
  • suction cups are used to achieve a removable interconnection between an object and an essentially smooth surface, which suction cups are constituted by cap, made of elastically deformable plastics, generally having a hemispherical or frusto- conical or cylindrical shape, with one or more annular grooves formed on its lateral surface.
  • cap means On top of the cap means are generally provided for connecting and/or supporting the same, such as for example suitable pins or small cylinders, hollow and internally threaded, adapted to allow the interconnection of the cap for example to an object which is to be fixed in a removable way to a surface by means of the suction cup, or also to a handle if the suction cup is, for example, used to manually move glass or metallic sheets.
  • a radial block protrudes from the base of the cap outwardly therefrom, which radial block exerts the function of gripping means for facilitating the lifting of a short portion of the perimetral edge of this base in order to allow air to enter within the cap.
  • suction cups In order to obtain a high gripping action it is therefore necessary to use a plurality of adjacent suction cups; the suction cups, however, must be arranged such that the radial block protruding from the same can always be reached by the user in order to allow its lifting.
  • the suction cups cannot be uniformly distributed along the whole base of an object, but must be arranged only at the perimetral edge of said base, in order to be easily reachable by the user for lifting the same, all this limiting the overall gripping action which may be achieved.
  • suction cups are in use in which the depression inside the cap is obtained by sucking the air from the same by means of a pump or, alternatively, by imparting a strong deformation to the cap by means of suitable levers.
  • suction cups are fairly expensive, in particular those which require a pump to suck the air.
  • the main purpose of the present invention is therefore that of solving the technical problems specified above, overcoming the drawbacks of the cited prior art and therefore devising an invention which allows to obtain a device for removable interconnection to a surface which may be associated to a desired element in order to removably attach the element to any desired surface.
  • another important object is that of achieving an invention which allows to removably attach a desired object to a surface, even when unevennesses or cracks are present in the latter.
  • Still another important object is that of achieving a device for removable interconnection to a surface which allows to achieve a high adhesion force to such surface.
  • Still another important object is that of achieving an invention which may be attached and detached from a surface in an easy and quick way.
  • Still another important object is that of achieving an invention which is structurally simple and has low manufacturing costs.
  • a device for interconnection to a surface which is characterized in that it comprises a base having a lower surface from which a plurality of suction cups are protruding, each of the suction cups comprising a cap from which at least one block is radially protruding, said block selectively interacting with the perimetral edge of an opening formed in a plate slidably associated below said lower surface by means of suitable guiding means.
  • FIG. 1 shows, in perspective view, a device according to the invention
  • FIG. 2 shows, in a bottom view, the base of the device of FIG. 1;
  • FIG. 3 is a view taken along the cross-section plane III-III of FIG. 2;
  • FIG. 4 shows, in a perspective exploded view, the device of FIG. 1 ;
  • FIG. 5 shows, in lateral view, the device of FIG. 1 in a fixing condition to a surface
  • FIG. 6 shows, in a view similar to the preceding one, the device of FIG. 5 during a detachment step from a surface
  • FIG. 7 shows, in a perspective view, a suction cup of the device of the present invention
  • FIG. 8 shows, in a cross-section diametral view, the suction cup of FIG. 7;
  • FIG. 9 shows, in a cross-section diametral view, a particular of the device of FIG. 1, in a fixing condition to a surface
  • FIG. 10 shows, in a view similar to the preceding one, a particular of the structure of FIG. 1, during its detachment from a surface;
  • FIG. 11 shows the particular of FIG. 10, in a cross-section view taken according to a plane perpendicular to the cross-section plane of FIG.10;
  • FIG. 12 shows, in perspective view, the base of an additional embodiment of a device according to the invention.
  • FIG. 13 shows, in perspective view, the second plate of the device the base of which is shown in FIG. 12;
  • FIG. 14 shows, in a bottom view, the base of FIG. 12.
  • an interconnecting device to a surface is indicated at 1 , which comprises a base 2, advantageously but not necessarily having a circular shape as seen in plan view, the base 2 being essentially T-shaped as seen along a diametral cross-section so as to define a substantially disc-shaped head 3 from which a shank 4 projects, which preferably has a star shape defining spokes joined together by means of concentric annular curbs.
  • a plurality of first holes 5, advantageously but not necessarily arranged according to a plurality of concentric arrays, are axially formed in the base 2 at the shank 4; advantageously, the first holes 5 are substantially T-shaped, as seen in cross- section view taken along a diametral plane of the base 2.
  • At least one peg 7 projects substantially perpendicularly from the lower surface 6 of the shank 4 of the base 2 close to each of said first holes 5.
  • a cavity 8 preferably substantially cylindrical, is formed from the lower surface 6 of the shank 4 of the base 2, approximately at the axis extending along the center of the base 2, a second through hole 9 being formed at the bottom of the cavity 8.
  • one or more third and distinct holes 10 are formed in the lower surface 6 of the shank 4.
  • a plurality of suction cups 11 are associable to the lower surface 6, each suction cup 1 1 comprising a cap 12, substantially cylindrical or frusto-conical, and made of an elastically deformable material.
  • the cap 12 has a concave lateral internal surface 13 and a substantially flat external lateral surface 14; at least a block 15, advantageously shaped as a circular sector as seen in plan view, projects from the lateral surface 14.
  • At least one annular groove 16, having a substantially semicircular cross-section, is formed along the external perimetral edge of the cap 12.
  • the suction cups 11 are provided with suitable connection means which are advantageously constituted by a small cylinder 17, advantageously hollow and internally threaded, integral with and axially and externally protruding from the external lateral surface 14 of the cap 12.
  • the suction cups 11 may be connected to the base 2 by means of known fixing means, such as first screws 18 which may engage the first holes 5 of the base 2, which screws may be fixed in the small cylinders 17 of said suction cups 11.
  • suction cups 1 1 are provided with angular positioning means with respect to the base 2, which means is advantageously constituted by a seat 19, formed along one generatrix on the outer surface of the small cylinder 17 from the free end of the latter and partially shaped so as to mate the pegs 7 protruding from the lower surface - O -
  • the pegs 7 may therefore be housed in the seats 19 of the various suction cups 11 , so as to determine the angular position of the suction cups with respect to the base 2.
  • each cap 12 selectively interacts with the perimetral edge of an opening 20 formed in a plate 21 slidably associated below the lower surface 6 of the base 2 by means of suitable guiding means.
  • the plate 21 is substantially circular as seen in plan view and has a diameter preferably slightly greater than the diameter of the head 3 of the base 2.
  • the openings 20 have a slightly greater diameter than the outer perimetral edge of the caps 12 and at the same time capable of preventing the passage of the block 15 protruding from the same caps 12.
  • the suction cups 11 are therefore arranged, in use, within the openings 20, and may protrude below the openings with their lower end and are limited in their position by the abutting cooperation of the block 15 with the perimetral edge of the corresponding opening 20.
  • the perimetral edges of the openings 20 are provided with a bevel 22 which reduces their diameter at the blocks 15.
  • the aforementioned guiding means of the plate 21 with respect to the base 2 advantageously comprises fourth holes 23, in the same number of the third holes 10 formed in the lower surface 6 of the shank 4 of the base 2, and arranged so as to face, in use, the third holes 10.
  • the aforementioned guiding means further comprises second screws 24, slidably connected to the fourth holes 23 and fixed at one of their ends to the third holes 10; the head of said second screws 24 abuts against the perimetral edge of the fourth holes 23, avoiding in this way that the plate 21 may be detached from the base 2.
  • the aforementioned guiding means comprises, in an additional embodiment, first small cylinders 25, substantially perpendicularly protruding from the plate 21 towards the base 2, and axially provided with a fifth hole 26, which also traverses the plate 21; advantageously, but not necessarily, the first small cylinders 25 are in number of three and are arranged substantially at the vertexes of a rectangular triangle.
  • the aforementioned guiding means further comprises second small cylinders 27, arranged in one ore more areas of the shank 4 among two of the spokes and the two annular curbs, the small cylinders 27 being present in the same number of the first small cylinders 25, arranged along the same axis and substantially facing the same; said second small cylinders 27 are advantageously traversed by a sixth hole 28, approximately arranged along the same axis of the fifth hole 26 of the facing first small cylinder 25 and traversing the whole base 2.
  • the portion of the sixth holes 28 traversing the head 3 of the base 2 has a shape such that i.e. an internally threaded hollow nut, not shown in the attached drawings, may be housed and blocked therein, by mechanical interference.
  • the second screws 24 are slidably associated to the fifth holes 26 of the first small cylinders 25 and to the facing sixth holes 28 of the second small cylinders 27, and are then fixed at one of their ends to said nuts associated to the sixth holes 28.
  • a device according to the present invention can be associated to a given object, not illustrated in the attached drawings, by fixing the head 3 of the base 2 to such an object by means of fixing means of known type, such as for example a suitable glue and/or suitable screws or rivets.
  • suction cups 11 ensure the connection of the device 1 to the surface even when the latter has cuts or unevennesses which may hamper the connection of some suction cups 11.
  • the lifting of the plate 21 allows to achieve a detachment of the suction cups - o -
  • the device according to the invention allows a high grip of its connection to the surface thanks to the presence of numerous suction cups.
