Definitions

  • the present disclosure refers to a clip, or connection article, suitable for support structures, or load-bearing structures, of false ceilings, i.e. support structures for plates or panels placed underneath a regular ceiling, which are connected to the ceiling by a so-called hanger, steel rods, an iron wire, bars or other coupling articles.
  • Support structures for false ceilings comprise a frame intended for supporting or propping of panels or plates, wherein the frame includes metal bars fixed and crossed by a special joint to ideally form a grid, the grid defining a bearing plane for the panels or plates of the false ceiling.
  • connection article or, as above said, the clip, includes a plate sheet metal body, intended to be fixed on one side to one end of a first metal bar, and on the other side inserted in and coupled to, e.g. by a detent, a slot of a second metal bar.
  • Another connection article or clip may be inserted in and coupled to the same slot, on the opposite side of the second metal bar, said connection article or clip being in turn connected to one end of a th i rd metal bar.
  • Said connection article alone or in pair with another connection article or clip, therefore provides at least two metal bars to be joined and fixed to each other in an area of intersection.
  • the clip in connection with this scope, the clip must ensure a connection to the second bar that ensures mechanical strength, to ensure in turn a safe joint between bars. Moreover, it is required the possibility of easily connecting and, if necessary, disconnecting the clip to/fro m th e second metal bar in a step of assembling/disassembling the support frame. In fact, it should be considered that during a phase of assembling/disassembling the frame of a false ceiling by an operator, normally the operator does not have a wide view of the clips. In fact often the operator works from beneath, with the arms up straight; therefore, the operator finds it difficult to see when a clip is correctly engaged or disengaged with respect to the slit of the metal bar.
  • an operator owing to the poor visibility available in carrying out the operations, works under uncertain conditions, as, by not seeing the clip, he/she is often forced to act in a random manner with said tool, or by exerting a manual forcing, and therefore has no way to know "for certain” that the clips have been disengaged (released) from the metal bar.
  • the present disclosure stems from the technical problem of providing a connection article or clip for bars of false ceilings allowing to overcome the drawbacks mentioned above with reference to the known art, and/or attain further advantages or features.
  • connection article, or clip according to independent claim 1 , a combination of a connection article or clip and a bar for false ceilings according to claim 16, a support structure for a false ceiling according to claim 22 and a process for actuating a clip according to claim 23.
  • the clip includes a bridge sheet metal portion provided with an engagement zone or engaging element, for engaging to a counter-engaging element, e.g. associated to the slit of the metal bar.
  • the bridge sheet metal portion has, according to the present disclosure, elastic properties or configuration, i.e. is structured so as to exhibit elastic behavior when subjected to a momentary deforming action, such that, as the momentary deforming action ceases, the bridge sheet metal portion returns to the original position.
  • the bridge sheet metal portion can assume a first position, or initial position, wherein in the first position the bridge sheet metal portion is in a resting condition, and at least one second position, wherein in the second position the bridge sheet metal portion is in an elastically deformed, highly unstable condition (second position), in the second position said bridge sheet metal portion being temporarily flexed with respect to the initial position.
  • the bridge sheet metal portion may be construed as an element that serves or acts as a button connected to the remaining portion of the sheet metal body (which can be pressed and momentarily flexed) and that exhibits elastic return.
  • a displacement of the engaging element is obtained which provides a practical release from the counter-engaging element of the metal bar.
  • the bridge sheet metal portion may be a sheet metal piece that is cut sideways with respect to a remaining part of the clip and thereafter is integrally joined at the ends with the remaining portion of the clip and that, after the cutting, is then shaped.
  • the sheet metal portion is a portion which has been elongated, or a portion longer than the slot in which it is located.
  • the bridge sheet metal portion is a sheet metal piece longer, i.e. elongated, than a remaining part of the plate sheet metal body to which the bridge sheet metal portion is fixed.
  • This elongated configuration allows to the bridge sheet metal portion, when it is pressed, to be subjected to a temporary compression in the longitudinal direction before reaching the second position.
  • the bridge sheet metal portion can assume an intermediate condition, between the first position and the second position mentioned above, wherein such intermediate condition is highly unstable, and is due to a momentary compression in the longitudinal direction.
  • the unstable intermediate position (of compression) can be both a transitory position, when pressing the bridge sheet metal portion to the second position at the time of clip release, and an unstable position that may be assumed at the time of clip engagement.
  • the unstable intermediate position can be assumed at the time of an engagement of the clip to the bar, when the clip is partially inserted in the slit of the bar.
  • the bridge portion can be inserted in a slit of a metal bar and can be elastically deformed, e.g. by compression, to allow the engaging element to pass over the slit until engagement with the counter-engaging element associated to the metal bar, optionally with a typical "click' of concluded engagement.
  • the bridge sheet metal portion can assume an unstable intermediate position (of compression) that can foster the engagement of the clip to the metal bar.
  • Said unstable intermediate position (of compression) is automatically assumed by the bridge sheet metal portion, thanks to the fact that the bridge sheet metal portion is elongated, and, at the time of engagement of the clip, may be obtained without any pressure exerted by an operator on the bridge sheet metal portion.

  • FIG. 12 shows an enlarged scale view of a detail of a metal bar according to the present disclosure.
  • a clip or connection article for a support frame of a support structure of a false ceiling is denoted by reference number 1 .
  • the clip 1 is fixed to a metal bar 2, which in the example has a T-shaped section, and is obtained by bending a sheet metal, in order to obtain an overlap of two sheet metal portions.
  • the metal bar 2 can be different from the one illustrated, for instance of different section, as for example, it can be a C-shaped or U-shaped section, or even of a further different T-shape/section.
  • the clip 1 can be inserted in a slit 4 of a second metal bar 2, to be engaged with an edge defining the slit 4 in the metal bar 2.
  • another clip 1 can be inserted, which is in turn fixed to an end of a third metal bar 2, to form an area of intersection, or crosslike configuration, of a support or propping structure for a false ceiling.
  • the two clips 1 are inserted from opposite sides in the same slit 4 of the metal bar 2, and are both connected to opposite sides of the metal bar 2 in the slit 4. As visible from the figures, the two clips 1 , when seen from one side, are partially overlapped in the slit 4.
  • a single clip 1 fixed to one end of a first metal bar 2, is intended to be inserted alone in a slit 4 of a metal bar 2, orthogonal to the first bar, for instance in the region of a side wall of the false ceiling, where it is impossible to form an intersection.
  • Each clip 1 includes a plate sheet metal body 3 formed by a first clip portion 1 1 including a slot 5 or cavity, wherein said first clip portion 1 1 is intended to be removably inserted and engaged in the above-mentioned slit 4 of the bar 2.
  • the clip 1 includes a second clip portion 21 intended to be fixed to the metal bar 2.
  • the present disclosure relates in particular to the first clip portion 1 1 for connection with the slit 4 of the metal bar 2; it follows that in the following description the second clip portion 21 will not be described, it being understood that it can be made with slits, retainers, fins or other types of connection elements according to the needs for connection to the metal bar 2.
  • the connection is obtained by riveting of a portion 23 of the clip, e.g. having the shape of a collar or circular crown, inserted and riveted in corresponding holes of the metal bar.
  • the plate sheet metal body 3 includes, in the first clip portion 1 1 , a bridge sheet metal portion 25, which has free side edges 28, 29 and ends 26, 27 of the bridge integrally fixed, or formed as one piece with a remaining portion of the plate sheet metal body 3, which actually surrounds the bridge sheet metal portion 25.
  • the bridge sheet metal portion 25 is obtained by two cuts in the first clip portion 1 1 , wherein such cuts define the above-mentioned slot 5 or cavity.
  • the engagement zone 22 is present, intended for engaging with a counter-engaging element connected to the slit 4 of the above- mentioned second metal bar 2.
  • the engagement zone 22 comprises a detent 22a formed by a thin plate cut and bent, projecting with respect to a remaining part of the bridge sheet metal portion 25.
  • the counter-engaging element is the edge of the slit of the metal bar 2.
  • the engaging element of the clip can be a hole adapted to be engaged by a detent (counter-engaging element) associated to the edge defining the slit 4 of the metal bar 2.
  • an operative front side where the engaging of the second metal bar 2 in the slit 4 occurs, and a rear side or back, opposite to the operative front side, are defined in the clip 1 .
  • the bridge sheet metal portion 25 exhibits elastic behavior, i.e. is structurally elastic, and is adapted to assume a first position, wherein in the first position the bridge sheet metal portion 25 projects in a cantilevered manner with respect to the slot/cavity 5 of the plate sheet metal body 3 (on the side of said operative front side), and a second position, wherein in the second position the bridge sheet metal portion 25 is in an elastically deformed condition, for instance, being deformed following a pressing action exerted, e.g. with a finger, towards the slot 5 on the bridge sheet metal portion 25, i.e. towards the rear side or back of the clip 1 .
  • elastic behavior i.e. is structurally elastic, and is adapted to assume a first position, wherein in the first position the bridge sheet metal portion 25 projects in a cantilevered manner with respect to the slot/cavity 5 of the plate sheet metal body 3 (on the side of said operative front side), and a second position, wherein in the second position the bridge sheet metal portion 25 is
  • the elastic deformation of th e bridge sheet metal portion 25 causes a displacement of the engaging element 22a, as may be seen from a comparison of figures 5 and 6, or of figures 8 and 9, and provides the clip 1 to be disengaged from the slit 4.
  • the bridge sheet metal portion 25 is a sheet metal piece longer, i.e. it has been suitably elongated, than the slot 5 or cavity in which it is housed.
  • longer it is meant that a linear development of the bridge sheet metal portion 25 on a plane has a length greater than the linear length of the slot 5.
  • the bridge sheet metal portion 25 is a piece of sheet metal having at least partially a curved configuration and presenting a convex external surface 24, on which a pressure adapted to deform the bridge sheet metal portion 25 is exerted.
  • the bridge sheet metal portion 25 is longer than the slot 5, by exerting a pressure on the bridge sheet metal portion 25, said bridge sheet metal portion 25 is subjected, at first, to a compression in the longitudinal direction at the time of a passing in the cavity 5, and is then completely flexed beyond the cavity 5 to assume the second position.
  • the reaching of the second position by the bridge sheet metal portion 25 can determine, when touched , a certain vibration, click, or in general a "tactile sensation", corresponding to a sort of "end-of-stroke" of the displacement of the bridge sheet metal portion 25 and allowing to obtain a correct positioning of the detent 22a for release from the edge of the slit 4.
  • the bridge sheet metal portion 25 is, or serves as a pressure button, with elastic return.
  • the bridge sheet metal portion 25 can assume at least three distinct positions.
  • An initial position, i n the absence of pressing action, is the first position mentioned above.
  • a final position which is the second position, in the presence of a pressing action, wherein the bridge sheet metal portion 25 is completely pressed and flexed, the final position corresponding to a condition of total loading or of end-of-stroke, with automatic return to the initial position as the pressing action ceases.
  • the reaching of said final position provides the above-mentioned "tactile sensation" of a correct positioning of the detent 22a which allows release from the slit 4.
  • said unstable intermediate position has also a second function, independent of that of passing through between the first position and the second position, and that therefore can be independent of a pressing action, e.g. exerted by the operator.
  • a pressing action e.g. exerted by the operator.
  • such an unstable intermediate position can be assumed by the bridge sheet metal portion 25 when the bridge sheet metal portion 25 is inserted in the slit 4, and the engaging element 22a interacts with the slit 4.
  • the bridge sheet metal portion 25 automatically compresses itself in the unstable intermediate position, slightly displacing the detent 22a so as to allow engagement of the engaging element 22a.
  • the first clip portion 1 1 is inserted in the slit 4 of the metal bar 2, with the operative front side facing the edge defining the slit 4, and the back of the clip facing a central zone of the slit 4.
  • the bridge sheet metal portion 25 is subjected to a compression deformation (the above-mentioned intermediate position) at the time of passing in the slit 4, so as to allow the detent 22a to pass over, in the slit 4, the edge of the metal bar 2. Thanks to the elastic properties of the bridge sheet metal portion 25, the detent 22a engages stably against the wall of the metal bar 2. Insertion of the detent 22a in the slit 4 is also fostered by the curved configuration of the bridge sheet metal portion 25, defining a sort of lead-in or tilted plane at the time of insertion.
  • the elastic return moreover fosters a release or disconnection of the clip from the metal bar 2.
  • a complete deformation of the bridge sheet metal portion 25 is obtained (the above- mentioned final position) causing a displacement of the detent 22a associated thereto with respect to the metal bar 2.
  • the curved shape of the sheet metal portion, and in particular of the convex surface 24 of the bridge sheet metal portion 25, allows an operator to recognize by touch the bridge sheet metal portion 25 and to act thereon without hesitation, to release the clip 1 from the slit 4.
  • the elastic deformation of the bridge sheet metal portion 25 may be "felt" by touch from an operator, thanks to the fact that, as said, at the time of the end-of-stroke, the operator feels a sort of vibration, or click (and in general a "tactile sensation").
  • the bridge sheet metal portion 25 includes a first bridge part 30 and a second bridge part 32.
  • the first bridge part 30 is longer than the second bridge part 32.
  • the above-mentioned engagement zone 22 or region, i.e. the detent 22a, is associated to the second bridge part 32.
  • a bending line 33 is interposed between the first bridge part 30 and the second bridge part 32, the bending line defining a groove or recess between the first bridge part 30 and the second bridge part 32.
  • the bending line 33 defines a groove on the convex external surface 24.
  • the bending line 33 defines a sort of interruption of the curvature of the bridge sheet metal portion 25.
  • the first bridge part 30 and the second bridge part 32 have a downward-facing concavity
  • the bending line 33 defines a recess having a V-like profile, with an upward-facing concavity.
  • the bending line can have another shape different from a groove shape, e.g., it can be bent so as to have a double groove.
  • the bending line 33 defines a dovetail profile with the first bridge part 30 and the second bridge part 32.
  • This deformed position is highly unstable, or transient, i.e. it is not possible to hold such position if not by keeping up a continuous and high pressing action.
  • Such condition moreover causes a remarkable flexing of the ends 26, 27 with respect to the remaining portion of plate sheet metal body 3. It follows that as soon as the force applied on the first bridge part 30 ceases, and the user releases the clip 1 , the ends 26 and 27 return to their original position of resting, and the entire bridge sheet metal portion 25 returns to an undeformed condition.
  • the clip 1 has straps 80, 81 or connecting portions interposed between the end 27 of the second bridge part 32 and a free end 82 of the clip 1 .
  • straps 80, 81 are subjected to a momentary torsion, which contributes to obtain said effect of vibration, click or of tactile sensation of the bridge sheet metal portion 25.
  • the flexibility of the bridge sheet metal portion 25 is increased to the utmost.
  • the bending line 33 is close to the detent 22a, i.e. the bending line 33 is adjacent and very near to the detent 22a. Thanks to this configuration a high flexion of the detent 22a is obtained. This configuration allows maximizing displacement of the detent 22a, i.e. to obtain a maximum stroke or travel of the detent during the disengaging.
  • first bridge part 30 Apart from the greater length of the first bridge part 30 with respect to the second bridge part 32, flexibility can be further fostered by the presence of a relief hole 35 in the first bridge part 30.
  • the clip 1 has a profile suitable for a correct and univocal insertion in the slit 4 of the metal bar 2.
  • the clip 1 comprises a substantially plane central region 12, wherein the slot 5 and the bridge sheet metal portion 25 are located. Besides the central region 12, the clip 1 comprises a first lateral region 13 and a second lateral region 14, wherein the first lateral region 13 and the second lateral region 14 are wings diverging the one with respect to the other.
  • the first lateral region 13, the central region 12 and the second lateral region 14 have a substantially trapezium-like profile.
  • each of the first lateral region 13 and the second lateral region 14 has a step-like profile, i.e. each of the first lateral region 13 and of the second lateral region 14 includes a first part 15 higher than a second part 16.
  • the process is substantially as follows.
  • the process is carried out by a so-called pitch die.
  • a rolled metal strip is provided.
  • the material used allows to have sufficient elongation and a high mechanical strength; among others, in the specific instance said material is stainless steel with >8% elongation, carbon steel and alike metals.
  • the strip has a height of 17mm.
  • a shearing with drilling is carried out, in order to make the individual plate sheet metal bodies 3, and for each of them the slot 5 (to define the bridge sheet metal portion 25) and the holes at the crown- shaped portions 23.
  • the plate sheet metal body 3 is subjected to bending, to form the diverging wings, i.e. the first lateral region 13 and the second lateral region 14 of the plate sheet metal body 3.
  • the bridge sheet metal portion 25 is subjected to a double step of deep-drawing.
  • a positive deep-drawing is carried out in order to bring the bridge sheet metal portion 25 out of the plane of the remaining portion of the plate sheet metal body 3 and therefore of the cavity 5, to form said convex surface 24.
  • an elongation of the bridge sheet metal portion 25 is carried out. (As said above, the elongation allows to compress the bridge sheet metal portion 25 when said pressing on the convex surface is carried out, and obtain the second deformed position of the clip or the intermediate position).
  • the metal bar has a slit shaped so as to house, substantially univocally, the clip, and in particular the first portion 1 1 of the clip 1 . More specifically, the slit 4 of the metal bar has a shape complementary to the profile of the clip 1 and allowing to guide the insertion of the first clip portion 1 1.
  • the slit 4 is symmetrical with respect to a plane (identified in Figure 12 by a dashed line P) passing orthogonal through the metal bar 2.
  • the slit 4 of the metal bar 2 comprises a first recess 40, having, e.g., a substantially trapezoidal profile, a second recess 41 having, e.g., a substantially trapezoidal or squared profile, and a third recess 42 having, e.g., a substantially trapezoidal profile.
  • a first tab 45 is present between the first recess 40 and the second recess 41 , the first tab being projecting towards a central zone of the slit 4 and having, e.g., a substantially trapezoidal profile.
  • a second tab 46 is present, between the second recess 41 and the third recess 42, the second tab 46 being also projecting in the slit 4, and having, e.g., a substantially trapezoidal profile.
  • the first recess 40 is intended to receive the first lateral region 13 of the clip 1
  • the third recess 42 is intended to receive the second lateral region 14 of the clip 1 . It may be observed that the clip 1 is inserted by sliding, making the first lateral region 13 slide in the first recess 40 and making the second lateral region 14 slide in the third recess 42.
  • the bridge sheet metal portion 25 deforms slightly elastically (intermediate position), to allow the detent 22a to pass over the edge of the metal bar 2 defining the second recess 41 in the slit 4.
  • the detent 22a When the edge is passed over, thanks to the elastic return of the bridge sheet metal portion 25, the detent 22a cooperates with the edge of the metal bar defining the second recess 41 , interacting by interference.
  • the detent 22a passes over the edge of the metal bar 2 in the slit 4 and engages on the wall of the metal bar 2.
  • the clip 1 remains blocked thanks to the fact that the shoulder 17 of the first lateral region 13 and the shoulder 17 of the second lateral region 14 abut against the opposite surface of the metal bar 2. It follows that the metal bar 2 remains trapped between the shoulder 17 and the detent 22a.

  • the two clips are arranged upturned the one with respect to the other.
  • the back or rear side of the first bridge part 30 of a clip 1 faces the back or rear side of the second bridge part 32 of the second clip 1 , and vice versa.
  • This upturned arrangement provides space in order to deform the bridge sheet metal portion 25 and remove the engaging of the engaging element 22a with the slit 4.
  • the bridge sheet metal portion 25 can be pressed with a sufficient space thanks to the fact that it is displaced towards the back of the second bridge part 32 of the other clip, back which is concave, and where it is further present a recess defined by the detent 22a. Therefore, to the bridge sheet metal portion 25 an increased stroke is allowed, thanks to the fact that the second bridge part 32 of the other clip 1 opposite thereto leaves a space sufficient for the movement of the first bridge part 30 of the first clip 1.
  • each clip 1 in the slit 4 allows to avoid arranging separators or guides in the slit 4 for guiding the insertion of the clip 1 . Therefore, the slit 4 offers the greatest possible space to house the pair of clips 1 .
