Abstract

Description

Scope of the invention

[0001] The present invention relates to a support device for objects in general, preferably furniture and furnishings (particularly in nautical environment), which device (one or more than one) supports an object thus allowing easy and immediate levelling adjustment on the rest ground.

[0002] In particular, the invention relates to this support device 1 which allows lifting and / or lowering the rest base surface of the device itself by means of a simple screw mechanism thereby varying its overall height from the ground.

[0003] In this way levelling of objects supported by it may be easily adjusted.Brief outline of prior art

[0004] As is known, in many technical fields it is necessary to adjust the correct levelling of some objects.

[0005] Many of these objects, in fact, require perfect levelling so that their base can be perfectly parallel to an ideally horizontal plane.

[0006] In a practical case, for example, it might be necessary to level a rest frame that is built on a floor. Since the flooring is not necessarily horizontal and precise, especially if it is uneven, if the correct levelling is not carried out the frame will be inclined. In this way, the objects intended to be placed on this frame will also be inclined.

[0007] This is also valid for furniture in general, such as for example wardrobes, dressers, etc. Above all in nautical and aeronautical field, furniture must be perfectly levelled as compared to the flooring on which it lies, that is it lies perfectly with the base parallel to the ground. Unwanted inclinations, for example also due to imperfections of flooring, must be adjustable and compensated given that, otherwise, a risk of overturning and / or inaccurate opening of doors could occur. Manufacturing inaccuracies of the base of furniture could determine its unwanted inclination which must be corrected.

[0008] In addition, in nautical and aeronautical field, sailing determines wavy or anyway stormy motions which obviously influence functioning and stability of furniture in a particularly different way as compared to static situations like homes. Therefore, correct arrangement without inclinations is an important element.

[0009] Therefore, in all fields, but in particular in nautical and / or aeronautical field, the need to be able to adjust levelling of an object quickly and precisely is felt.

[0010] To the current state of the art, there is no suitable solution to the issue, and often one resorts to makeshift solutions such as applying shims in specific points relative to the support of the object.

[0011] Obviously, this solution is not optimal and versatile and is also incompatible with needs which one may have in nautical or aeronautical field.

[0012] A possible check carried out with the known tool to verify inclination (for example the spirit or laser level) could continue to indicate an unwanted presence of inclination that cannot be easily resolved.Summary of the invention

[0013] Therefore, the aim of the present invention is to provide a device which solves at least partially said technical inconveniences.

[0014] In particular, the aim of the present invention is to provide a levelling device which allows not only supporting an object with respect to the ground but also its levelling adjustment simply and quickly also when the object is already laying on said device.

[0015] These and other aims are therefore achieved with the present levelling device, in accordance with claim 1.

[0016] This levelling device 1 is adapted to support any object, for example a decor item or furniture in general, and comprises: A frame (2a, 2b) having a rest base (22) in such a way that said device can be supported, in use, on the ground or on a floor in general and, on the opposite side, a support base (10; 63) through which said object is supported; A gear system (d1, d2, 4) at least partially contained in said frame and comprising an end (3a') of a pin (3a), whose said end extends at least partially outside said frame to be activatable into rotation; and wherein said end (3a') of the pin (3a', 3a) controls, through its rotation in one direction or in the opposite direction, the activation of said gear system (d1, d2, 4) which, when activated, causes translation upwards or downwards of said support base (10; 63).

[0017] Therefore, in use, the object lies and is supported by the rest base of one or more of said devices (depending on the size of the object one or more devices may be necessary).

[0018] Therefore, according to the invention, this pin which can be driven into rotation controls, through its rotation in one direction or in the opposite direction, activation of the gear system of which it is part and which controls translation upwards or downwards of the levelling device as a whole, and therefore integrally, of said support base.

[0019] In this way, all the aforesaid technical disadvantages are readily solved.

[0020] Thanks to the pin, which may have for example its end (3a') protruding from the frame, the operator may easily activate the gear system which causes lifting or lowering of the support base on which the object rests.

[0021] Therefore, once the object has been firmly arranged for example on more than one of said devices, the operator may place a regular level, for example a spirit level, on the object to see whether it is perfectly levelled or not. In case of need, the operator may act manually independently on each of said objects by rotating, for example by means of suitable tool, the pins of each of them, thereby causing translation upwards or downwards of the support base on which the object rests.

[0022] Substantially, the overall height of the whole levelling device varies thereby lifting or lowering the supported object.

[0023] The stroke may be in the order of millimeters for example, but it allows lowering and / or lifting all rest points of the object until the levelling tool (for example said spirit or laser level) marks reaching of the desired position.

[0024] In this way, immediately, all required adjustments may be performed once the object has been firmly arranged on one or more of said devices.

[0025] Therefore, this levelling device constitutes a real rest base for the object and with the object which is no longer removed from above said devices.

[0026] Depending on the type of object, for example a wardrobe, one may select the adequate number of devices which are laid on the ground and on which the wardrobe is firmly fixed. At that point, if the wardrobe must be levelled, then one proceeds as indicated above.

[0027] Advantageously, said gear system (d1, d2, 4) comprises a first part (3a, 3b) of said gear system which is cooperating with a second part (3c) of this gear system.

[0028] More in particular, advantageously, said first part comprises said pin (3a) comprising its said end (3a') activatable into rotation in order to drive the pin into rotation (rotation around its longitudinal axis of the end and obviously of the pin) and with said pin equipped with, on the side opposite to said end (3a'), a helicoidal threading (d2) (therefore helicoidal toothing).

[0029] Advantageously, said second part of the gear system comprises a spur-wheel (3b) (rotatable around its longitudinal axis) meshing with said helicoidal threading (d2) in such a way that rotation of said pin (3a) determines rotation of the spur-wheel (3b) through engagement of the teeth (d1) of said spur-wheel with the helicoidal threading (d2).

[0030] Advantageously, the spur-wheel is placed with its rotation axis (longitudinal axis) orthogonal with respect to the rotation axis (always longitudinal axis) of the pin.

[0031] Advantageously, the spur-wheel (3b) has a threaded axial channel (indeed coincident with the longitudinal axis of the spur-wheel and therefore coincident with the rotation axis).

[0032] According to this solution, advantageously, this second part of the gear system further comprises a threaded rod (4) which is inserted into said threaded channel of the spur-wheel and meshing with the threading of said axial channel of said spur-wheel.

[0033] In this way, advantageously, rotation of the spur-wheel determines translation of the threaded rod (4) by meshing the threading of the threaded rod (4) with the threading of said axial channel of the spur-wheel.

[0034] Substantially, the axial channel of the spur-wheel functions as a sliding guide.

[0035] Advantageously, said first part of the gear system and the spur-wheel are arranged inside the frame.

[0036] In addition, advantageously, said threaded rod (4) protrudes from a base (5).

[0037] Advantageously, the frame comprises an upper part (2a) comprising said support base (10, 63) through which said object is supported and a lower part (2b) comprising said rest base (22) to rest on the ground.

[0038] Advantageously, the upper part and the lower part of the frame contains said spur-wheel (3b) and are axially holed to form a passage channel aligned with the channel of the spur-wheel arranged inside.

[0039] In this way, advantageously, said threaded rod (4) can pass through said two parts of the frame passing through the channel of the spur-wheel with which it is meshing through the reciprocal threadings.

[0040] Advantageously, therefore, according to this solution, the rotation in one direction or in the opposite direction of the spur-wheel determines a translation of the threaded rod along the channel of the spur-wheel with which the threaded rod is meshing with a consequent moving-away or approaching of said base (5), from which the treaded rod (4) protrudes, with respect to the rest base (22).

[0041] Advantageously, further one or more guide rods (6) protrude from said base (5), each one inserted into a respective guide hole (6') of the frame.

[0042] Preferably said one or more guide holes (6') may be obtained in the lower part of the frame.

[0043] Advantageously, said base (5) as a function of the movement of the gear system, is movable between an extended position in which it extends externally from the rest base (22) thereby determining a lifting of the whole device from the ground on which it rests and a retracted position in which it moves close to the rest base (22) thereby lowering the whole device.

[0044] For example, advantageously, a seat or recess may be provided in which the base 5 is inserted in a retractable way which is thus flush with the rest base 22 in said retracted position.

[0045] Advantageously, a flanged accessory (60) may be comprised which can be coupled with the support base (10; 63) of the frame and comprising a support surface of flanged type for the object.

[0046] In this way a better base for supporting the object would be achieved.

[0047] Advantageously, a control rod (70) may be comprised, for example in the form of an accessory which may be used when needed.

[0048] Furthermore, the device may comprise a second pin (3a', 3a) which can rotate freely.

[0049] In particular, said second pin may have its two free ends and at least partially accessible and protruding from the frame.

[0050] In this way, advantageously, said control rod (70) can be connected at an end thereof to a free end of said second pin and, at the other end thereof, said control rod (70) can be connected to the end (3a') of a further device placed at a distance.

[0051] In this way, advantageously, by rotating the end (3a') of the device (1) its overall height may be adjusted normally as already described and, further, by rotating the end of the second free pin to the part opposite to that of connection to said control rod (70) the rotation of the control rod (70) is obtained.

[0052] Obviously the second pin has undercuts (for example with hexagonal shape) to be engaged with the end of the rod 70 (the two ends of the rod 70 may be identical) which provides, like a lug wrench, the cavity conformed to receive said shaped end of the pin.

[0053] Since the control rod is / may be connected to another twin device 1, then this control rod transmits its rotation to the end (3a') of the pin of said further device with which said pin (70) is connected, thus determining a variation of height thereof. Also the connection of the rod 70 with the further end of the pin relative to the further device 1 occurs through conformation of this end of the rod 70 in the form of lug wrench or the like, as described above.

[0054] In this way, by acting on only one part on only one device, one also adjusts a second device placed at a distance.

[0055] Another object of the present invention is an assembly which comprises an angle bar (300) comprising at least two tongues (301) which protrude therefrom and adapted to be inserted into a seat of a section bar (100) in such a way that two section bars (100) can be connected to each other in succession through said angle bar which functions as connection.

[0056] In addition, advantageously, the assembly also comprises a device, according to one or more of the previous features described above, and coupled with said angle bar.

[0057] In this way, through the assembly described above frames equipped with devices as described and therefore adjustable according to levelling may be created.

[0058] Advantageously in a preferred way, said at least two tongues (301) are placed to form a right angle between each other in such a way that the two section bars can be connected to each other through said angle bar according to a right angle.

[0059] In this way quadrangular or rectangular frames may be created.Brief description of the drawings

[0060] The present invention concerns a device (1) which, with a simple gear mechanism, allows lifting and / or lowering the rest surface of the device itself to the ground, thereby varying its height from the ground (substantially it can be lifted and / or lowered). In this way, levelling of the supported objects can be adjusted.

[0061] For a better understanding of the present invention, now a preferred embodiment is described only by way of nonlimiting example, with reference to the attached drawings, wherein: Figure 1 shows in an exploded view an axonometric view of the device in accordance with the invention; Figure 2 shows an axonometric view of the device; Figure 2A shows the flanged accessory 100 which may be applied to the device to better conform a support surface for the object, possibly it can be fixed better through screws or inserts which pass into the holes of the flange; Figures from 3 to 6 show axonometric view by removing part of the frame of the device, thereby showing the inner screw mechanism for adjustment; Figure 7 shows an application example of the device to a rod which, together with other rods, can constitute a rest base for the object and, therefore, with said base adjustable in height, that is which can be levelled; Figure 8 shows an exploded view of a particularly advantageous variant. Description of some preferred embodiments

[0062] With reference to figure 1, it shows an exploded view to highlight the structural parts of the device 1 object of the invention.

[0063] Therefore, the device 1 comprises a frame 2 (visible assembled in figure 2) which, as shown in the exploded view of figure 1, may comprise an upper part of frame (2a), a lower part of frame (2b).

[0064] Between the upper part of frame (2a) and the lower part of frame (2b) a first part (3a, 3b) of a gear system 3 is housed which cooperates with a second part (3c) of this gear system, as better described below.

[0065] The gear system is responsible for lifting and / or lowering of the described device, in such a way as to lift and / or lower the object or the supported portion of the object.

[0066] More in particular, the upper part of frame (2a) comprises an upper surface (also called support base) which is the one intended to support the object in use.

[0067] In the exemplifying case, said upper surface (or support base) may be of circular type given that it is generated by a cylindrical body 11 having a circular edge 10 and with said cylindrical body 11 rising from the base 12. Obviously, the cylindrical shape is not essential and therefore the circular shape of the edge 10 is not necessary.

[0068] In the exploded view of figure 1, only with the purpose of descriptive clarity, a closure lid which closes the axial channel formed by the cylindrical body 11 has been removed.

[0069] Therefore, this lid could be a simple disc which closes and is applied around the edge 10.

[0070] In a preferred variant of invention, as shown in figure 2A, the channel delimited by the edge 10 may be closed by a further accessory which comprises a flanged tubular body whose tube is inserted by interference into the channel of the cylinder 11. The opposite flanged part is protruding outside this channel and has a flange with holes for passage of screws and inserts. This allows firm and good fixing of said device to the object.

[0071] Therefore, this flanged tubular (which is an accessory) is depicted in figure 2A and comprises a tube 61 adapted to be inserted and locked into the channel of the cylinder 11. The upper part of this tube forms a flanged body (62, 63) which ends indeed with a flange 63 equipped with one or more holes for passage of inserts, screws or similar connection systems.

[0072] In this way, the object may rest on a good support base constituted by said flange 62 and may be screwed through the holes 64 and passage of said screws or inserts and the like.

[0073] Of course, the kinematic lifting / lowering motion described below of the whole device is transmitted integrally to this accessory 60, in case it has been used as per figure 2A.

[0074] Still as shown in figure 1, the upper part of frame (2a) is axially hollow and therefore it forms said passage channel which functions as passage of the threaded rod 4 as described below.

[0075] The lower part of the frame (2b) is such that it can be coupled with the upper part to form a sort of box-shaped element. The lower part (2b) is in plan form like a circular shape even if other shapes may be easily manufactured.

[0076] Therefore, the lower part (2b) forms a rest base to the ground 22 while, for the opposite side, it forms a seat 23 which functions as housing for at least part of the first part (3a, 3b) of the gear system which is then extended in a seat which follows its shape. In this way, the seat forms a entry path which facilitates correct assembly of the parts.

[0077] Also in this case, the lower part (2b) forms an axial channel which is obviously aligned with the channel of the upper part (2a) for passage of the threaded rod 4.

[0078] The part (3c) comprises the second part of the gear system which is cooperating with the first part as described below regarding functioning.

[0079] Therefore, from the structural point of view, said second part of the gear system comprises a threaded rod 4 with threading which is engaged with a gear of the first part of the gear system.

[0080] Then a base 5 is present, (generally this base is flat, for example with the shape of disc or circular). This threaded rod 5 (therefore connected integrally with said base 5) rises from this base which base engages and is then cooperating with the first part of the gear system.

[0081] Still from this base 5, at least one, preferably at least two vertical rods 6 rise, each one adapted to be inserted into a relative hole (6') of the lower base (2b). In this way, the vertical rods 6 (one or more than one) are sliding into said hole 6'. Therefore, each hole 6' forms a linear sliding guide along which the rod 6 may slide and which allows vertical translation of the whole assembly (3c) with respect to the lower base 22. In particular, by activating the first part of the gear system, it engages with the threaded rod thus causing translation of the whole assembly (3c).

[0082] Therefore, during assembly, one must take care to insert the threaded rod 5 along the two channels of the upper and lower part of the frame coupled with each other with the gears (3a, 3a', 3b) in the seat. Obviously, the rods 6, during assembly, must pass through the holes (6') in such a way that they project into the cylindrical channel delimited by the edge 10 (see figure 2 for this purpose).

[0083] In this way, we may anticipate that the whole assembly (3c) can be then translated with respect to the frame thus being able to slide with respect to it thanks to the guides (6') and therefore the base 5 can extend outside of the base 22 relative to the lower part of the frame 2b (as per figure 6) and can retract inside it (as per figure 5). This determines a variation of the overall height of the device with consequent lifting / lowering of the support base (10; 63) on which the object rests.

[0084] In more detail, structurally, the first part (3a, 3b) of the gear system comprises a pin (3a) which ends at an end thereof with an end part (3a') which may have such a conformation as to be easily grasped by a tool to cause its rotation, for example a lug wrench (for example hex wrench) . In fact, said end part (3a') may be conformed with hexagonal shape or any other type of undercut adapted to allow easy grasping also with tools such as pliers and causing its rotation. Therefore, the end part (3a') is an activation terminal where an operator, with suitable manual or automatic tool, such as a lug wrench or with an automatic machinery similar to the lug wrench, can activate this pin (3a) into rotation. On the opposite side the pin (3a) comprises a threading to form a single gear which is coupled with the gear of a sort of spur-wheel (3b).

[0085] Therefore, actually, the pin (3a) forms a helicoidal screw which is rotationally coupled with a sort of spur-wheel (3b).

[0086] Therefore, the spur-wheel (3b) is a cylindrical body which provides on the outside these teeth (d1) which are coupled with the teeth (d2) of the screw in such a way that rotation of the screw in one direction or in the opposite direction causes the relative rotation of the spur-wheel (3b) in a relative direction or in the opposite direction.

[0087] The cylindrical body of the spur-wheel (3b), in its turn, is axially holed in a pass-through way as well to allow passage of the threaded rod 4. This axial channel is threaded with a threading which engages with the threading relative to the rod 4.

[0088] Therefore, the spur-wheel is aligned with the two parts of frame and forming an axial channel axially aligned with the one of the two parts of frame, for allowing passage of the threaded rod 4.

[0089] In this way, now the kinematic motion is clear: By rotating the rod (3a) through the shaped end (3a'), one drives into rotation the threading (d2) (that is the helicoidal toothing d2) which, given that it is engaged with the straight-toothed toothing (d1) of the cylindrical body (3b), drives into rotation this cylindrical body.

[0090] The cylindrical body (3b) has the threaded axial channel which engages with the threading of the rod 4 which rod protrudes from the base 5 and is integral with it. In this way, depending on the direction of rotation of the cylindrical body (3b), translation of the rod 4 is determined, given that the threading of the channel of said cylindrical body is engaged with the threading of the rod 4. In this way, given that the whole block 3c is constrained to slide through the rods 6 and cannot rotate, it follows that rotation of the cylindrical body (3b) constrained in position determines sliding of the rod 4 along the channel of the cylindrical body (3b) which functions, actually, as activation system and guide of said rod 4. The spur-wheel from the cylindrical body is indeed locked and packed between the two parts of the frame and therefore cannot translate. At the same time the unit (3c) may only translate. It follows translation of the threaded rod 4 along the guide formed by the cylindrical body threaded inside (3b) with a consequent movement of the surface 5 as per figures 5 and 6. If the rod 4 translates downwards, the result will be, as per figure 6, that the surface 5 protrudes by projecting outside with respect to the base 22 of the lower part of the frame.

[0091] With an opposite direction of rotation, the base 5 retracts towards the base 22 as per figure 5.

[0092] The lower part of the frame may advantageously form a seat adapted to fully house inside it the base 5 (for example with the shape of disc).

[0093] In this way, in retracted position, the base 5 is aligned to the base 22 (see figure 5) while in extracted position the base 5 protrudes outside of the base 22 (see figure 6).

[0094] Anyway, in use, at this point, it is clear that by resting the whole device 1 on the ground, an object may be rested on this device (one or more than one depending on the size and / or shape of the object).

[0095] For example, if the object is firmly resting on four of these devices placed at any four angles of said object, at this point the object not only rests firmly but it can easily be levelled with respect to the ground if it is uneven.

[0096] For example, a spirit level may be applied on the object and then one may act on one or more of said devices by adjusting them in an independent way from each other, for example by acting on one or more of them depending on the cases.

[0097] For example, the pin relative to one of them may be rotated in such a way as to cause protrusion of the surface 5 as per figure 6 by a certain desired amount (for example few millimetres), in such a way as to incline the object by this lifting amount. In this way, the object may be levelled precisely thus also compensating for unevenness of the ground.

[0098] As per figures from 1 to 6, the device may be used as shown in said figures taking care to arrange under the object the necessary number of devices.

[0099] Figure 7 shows a variant of invention in which the two devices 1 as described are fixed to the ends of a section bar 100 which may be used, by combining it with other section bars, to form a rest plane for objects and with the rest plane that can be adjusted as described above.

[0100] Therefore, for this purpose, the device 1 may be fixed to an angle bar 300 fitted with tongues 301 placed at right angles between each other in such a way that each tongue can penetrate the relative raceway of the section bar. Specifically, the angle bar 300 can provide at least one tongue protruding from a part thereof (preferably at least two tongues) and, at right angle, at least one other tongue 301 protruding from another side thereof (preferably at least two tongues), in such a way as to assume indeed the shape of angle bar with right angle in which the two ends thereof (i.e. tongues) are made to be inserted by sliding into the two raceways of a section bar.

[0101] In this way, from each angle bar, to which the device 1 is connected in a preset space of the right angle, at least two tongues branch off at right angle between each other which are inserted in the raceways of a section bar. In this way two section bars in succession are connected at right angle with the device 1 integral with the angle bar.

[0102] This creates a base with square or rectangular shape, of which four of said described devices 1 are provided at the four angles of it allowing levelling adjustment thereof at each angle.

[0103] Fixing of the section bar to the tongues of the angle bar may occur with screws or inserts in general 200.

[0104] With reference to figure 8, a further variant of invention is described, which is identical to all what has been described so far, but it furthermore provides a control rod 70 which allows connection of two devices 1 in succession through a connection of the two ends of said control rod 70 with an end (3a') of each of said devices.

[0105] More in particular, in that case, each device, if it has been produced for this function, may provide two control points (P1) and (P2) and of which the point (P1) corresponds to the end (3a') already described which controls the gear system. The second point (P2) is identical to (P1) but it is in the form of a simple pin which therefore is not connected and does not activate any gear. It is merely a rotatable idle pin which is an engagement point (P2) for the rod 70 which is connected, by the end opposite to the end (3a') of the other opposite device (this end is obviously connected to the gear system of said further opposite device).

[0106] Advantageously, in this way, through (P1) a user may control and adjust the device relative to it and through (P2) may adjust the other device given that rotation of P2 is transmitted to the rod 70 and from it to the end (3a') of the other device with which the rod is connected by the opposite end.

[0107] In this way, also in case of arrangement of two devices very far from each other as per figure 8, the user may easily adjust both devices by acting on the same part.

[0108] This variant can be applied to the single devices described in figures from 1 to 6 thus providing presence of two pins as just described and the rod 70.

[0109] Equally, as shown in figure 8, this variant may also be applied to the device equipped and connected with angle bar (see figure 7). In this case, there is the angle bar as described in figure 7 to which the device described above is connected having the two pins (P1, P2) as per figure 8.

The device, according to one or more of the previous claims, wherein further one or more guide rods (6) protrude from said base (5), each one inserted into a respective guide hole (6') of the frame in such a way that the unit (3c) formed by the threaded rod (4) integral with said base (5) with said one or more guide rods (6) is constrained to have exclusively a translation motion; preferably said one or more guide holes (6') being obtained into the lower part of the frame.

7. The device, according to one or more of the previous claims, wherein said base (5), as a function of the movement of the gear system, is movable between an extended position in which it extends externally from the rest base (22) thereby determining a lifting of the whole device from the ground on which it rests and a retracted position in which it moves close to the rest base (22) thereby lowering the whole device.

8. The device, according to one or more of the previous claims, wherein a flanged accessory (60) is comprised which can be coupled with the support base (10; 63) of the frame and comprising a support surface (63) of flanged type for the object.

9. The device, according to one or more of the previous claims, comprising a control rod (70) and a second pin (3a', 3a) freely rotatable around its longitudinal axis, having its two free ends and at least partially accessible in such a way that said control rod (70) can be connected at an end thereof to an end of said second pin and, by the other end thereof, said control rod (70) can be connected to the end (3a') of a further device placed at a distance in such a way that by rotating the end (3a') of the device (1) its overall height is adjusted and by rotating the end of the second free pin to the side opposite to that of connection to said control rod (70) the rotation of the control rod is caused which thus determines rotation of the end (3a') of the pin of said further device with which said rod (70) is connected, thus determining a variation of height thereof.

10. The device, according to one or more of the previous claims, wherein the upper part of frame (2a) comprises a cylindrical body (11) and with said cylindrical body (11) rising from a base (12) and wherein the cylindrical body (11) is axially hollow thus forming said passage channel which functions as passage of the threaded rod (4) and wherein the lower part of frame (2b) is such that it can be coupled with the upper part to form a sort of box-shaped element.

11. The device, according to claim 10, wherein the lower part (2b) is in plan shape similar to a circular shape.

12. The device, according to claim 10 or 11, wherein the lower part (2b) forms a rest base to the ground (22) while, for the opposite side, it forms a seat (23) whose purpose is housing at least partially the first part (3a, 3b) of the gear system which thus extends into a seat which follows its shape.

13. The device, according to one or more of the previous claims, wherein the lower part (2b) forms an axial channel which is aligned with the channel of the upper part (2a) for passage of the threaded rod (4).

14. An assembly which comprises an angle bar (300) comprising at least two tongues (301) which protrude therefrom and adapted to be inserted into a seat of a section bar (100) in such a way that two section bars (100) can be connected to each other in succession and a device according to one or more of the previous claims coupled with said angle bar.

15. The assembly, according to claim 14, wherein said at least two tongues (301) are placed to form a right angle between each other in such a way that the two section bars can be connected to each other through said angle bar according to a right angle.
