Description

Assembly for structure for sectional door The invention relates to an assembly for structure, in particular guide for sectional door, in particular garage. Sectional door guide structures comprise one or more guide rails for wheels or rollers of hinged panels of the door.

These guide structures are often associated with separate elements, such as support sections, angles, connecting pieces, support elements, chutes, etc., with at least one of the elements having one or a series of elongated windows. The elements are attached to each other with a screw and a nut, the rod of the screw being engaged in the elongated window, so as to allow positioning of the elements between them by movement of the rod of the screw in the elongated window.

This type of fastening of the elements together is particularly difficult when the elements are located nearly 2m above ground level.

Moreover, even by using anti-rotation washers on the screw head side, a slight rotation on the nut side is still possible, which can then induce a relative translational movement of the elements between them, in particular during vibrations generated during door opening or closing operations.

This type of fastening also requires skill for the worker, because the latter must both hold the nut in position and position the shank of a screw opposite the nut, all with the interposition of a rail. Access to the nut for pliers or a spanner is often very complicated, if not impossible, which makes tightening or loosening operations difficult. This can then induce an attachment of parts to each other that is not adequate or insufficient, to ensure correct long-term attachment of elements to each other, and this despite vibrations following door opening and closing operations.

The invention aims to remedy this drawback, by using a connecting means allowing an automatic blocking effect of a part relative to the rail, to allow adequate tightening of the part to be secured to the rail. Such adequate clamping makes it possible to maintain parts on a rail with an adequate positioning.

The subject of the invention is thus an assembly for the structure (in particular of guidance) of a sectional door, in particular of a garage, the sectional door being advantageously motorized and subjected to tensile forces from one or more springs.

Said assembly according to the invention comprises: (a) an at least partially C-shaped metallic rail (1) (advantageously a guide rail for wheels or rollers of hinged panels) with (*) a core (1A) (advantageously associated with a series of elongated windows (1AF) with a predefined passage width (LP) and a length at least 2 times greater than the predefined passage width (LP), and (*) wings (1B, 1C) attached to said web (1A) and each advantageously having a return (1BR, 1CR), said at least partially C-shaped rail (1) defining an interior chamber (2) open by a longitudinal opening defined between the free edges of the wings (1B, 1C) or by an elongated window (1F) with a passage width (LP) defined between the free edges of the advantageous returns (1BR, 1CR) directed towards each other and a length at least twice greater than said passage width ( LP), said advantageous returns (1BR, 1CR) each having an inner face directed ve rs the open inner chamber (2) of the C-rail (1), the web (1A) of the C-rail (C) having an inner face (1AI) facing the open inner chamber (2), for which said C-rail C (1) comprises at least one or more elongated windows chosen from the group comprising a series of elongated windows (1AF) of the core (1A) and the elongated window (1F) defined between the returns (1BR, 1CR) of the wings (1B,1C); (b) a metal part (4) to be secured to said C-rail (1) with at least one passage (40) for a metal rod (50), or a combination of such a metal part (4) with a profile ( 6) adapted to slide in the inner chamber (2) of the C-rail (1), said profile having an inner face (61) facing the inner chamber (2) and one or more elongated windows (6F) with equal length at least twice the passage width of the elongated window - (6F) of the profile (6), and (c) a metal connection means (5) between the metal part to be secured (4) and a part of the said rail to the at least partially C-shaped (1), possibly in association with the section (6) adapted to slide in the inner chamber (2), to hold in position at least said metal part to be secured (4) at a predetermined location of said C-shaped rail (1), said metal connecting means (5) comprising at least one rod (50) adapted to be introduced into said passage (4 0) of said metal part (4) and at least one elongated window (1F, 1AF, 6F).

The assembly according to the invention comprises a particular connection means with a self-locking system for its part located in the inner chamber (2) of the at least partially C-shaped rail (1). This greatly facilitates the garage door frame assembly steps, allowing precise adjustment (by translation) of parts between them, even ensuring improved fastening, resistant to vibrations and shocks caused by the use of the door.

The metal connecting means (5) comprises at least one pair of parts cooperating with each other, this pair comprising: (a) a first part (5B) having a metal rod (50) with at least one threaded portion (50F), said rod being adapted to extend in the passage (40) of the metal part to be secured (4), said rod having a central axis (B-B) (axis corresponding to the axis of rotation of the rod) , and (b) a second part (5A) having a recess or a threaded passage (51) adapted to at least partially receive the threaded portion (50F) of said metal rod (50) of said first part (5B).

Said first and second parts (5A, 5B) are mounted to move between them by a movement of relative rotation between them around the central axis of rotation (B-B) to move them: (*) during a relative movement of rotation around of axis B-B in a loosening direction from a clamping position securing the part to be secured on a part of the C-shaped rail (1) to a non-clamping position, in which the metal connection means (5) and the metal part (4) to be secured can at least undergo a translational movement relative to the C-rail (1), and (*) during a relative rotational movement around the axis B-B in a tightening direction between a non-clamping position, in which the metal connecting means (5) and the metal part to be secured (4) can at least undergo a translational movement relative to the C-shaped rail (1) and the clamping position securing the metal part to be secured (4) on a part of the C-rail (1).

One (5B/5A) of the parts of the pair of parts (5A, 5B) cooperating with each other has a foot (52) with a bearing face (52A) intended to rest on the inner face ( 1AI) of the web (1A) of the C-rail (1) or on an inner face (61) of the section (6) or on the inner faces (1BRI, 1CRI) of the returns (1BR, 1CR) of the wings (1B , 1C) of the C-shaped rail (1), while the other (5A/5B) of the parts of the pair of parts (5A, 5B) has a support face (5AI) intended to rest on a face of the metal part to be secured (4) to said C-shaped rail (1).

Said foot (52) is shaped to allow its introduction into the open interior chamber (2) via at least one elongated window chosen from the group comprising the series of elongated windows (1AF) of the core (1A), the elongated window ( 1F) defined between the wings or the returns (1BR, 1CR) of the wings (1B, 1C) and the or the series of elongated windows (6F) of the profile (6), said foot (52) having a maximum width (LAM) less than the passage width (LP) of the elongated window(s) under consideration (through which the foot must be introduced) and a minimum length (LOM) corresponding to at least 1.7 times the passage width ( LP) of the considered window(s) into which the foot is inserted. This foot will serve as a fulcrum located inside the inner chamber. This support foot will thus be inside the chamber (2), that is to say in a protected zone.

Said one (5B/5A) of the parts of the pair of parts (5A, 5B) comprises one or more abutment means (53, 54) limiting the rotational movement of said foot (52) in the open interior chamber (2) between a first holding position for which the abutment means (53,54) is/are in contact with at least a first part of the C-shaped rail or with a first part of the section (6) or with at least one edge of an elongated window (1F, 6F, 1AF) to oppose a rotation of said one (5B) of said parts of the pair (5A, 5B) during a relative movement of rotation between the first part (5B) and the second part (5A) of said pair in a tightening direction, and with at least a second part of the C-rail (1) or with at least a second part of the profile (6) or with at least one edge of a elongated window (1F, 6F, 1AF) to oppose a rotation of said one (5B) of said parts of the pair (5A, 5B) during a — relative rotational movement between the first part and the second second part of the pair (5A, 5B) in a loosening direction. This or these abutment means serve as a means of blocking the abutment with respect to the C-shaped rail, possibly after a rotation of 45 to 135°, in particular of approximately 90°, which allows the operator not to have to take care to keep the stopper or the foot in position during a tightening or loosening operation. This also makes it possible to ensure that the parts are held together before they are fastened together. This also makes it possible, by using an automatic screwing machine with tightening torque adjustment, to be certain that the tightening of the connecting means is carried out with the predefined tightening torque. Thanks to this blocking means or abutment, it is possible to ensure the correct position of the abutment with respect to the rail or a profile or a window.

The thread of the threaded portion (50F) of the rod (50) of the first part (5B) 5 or at least part of this thread and the thread of the hollow or threaded passage (51) of the second part (5A) or at least a part of this thread are adapted to ensure a minimum clamping force between them, so as to allow at least, when the minimum clamping force is ensured between a part of the thread of the rod (50) and a part of the thread of the hollow or threaded passage (51) that, until the or at least one abutment means (53,54) of said one of the parts of the pair (5A, 5B) comes into contact with a face of the C-shaped rail ( 1) or a face of the profile (6) or an edge of an elongated window (1F, 1AF, 6F), a rotational movement of said other (5A/5B) of the parts of the pair (5A, 5B) on a predetermined sector causes a rotation of said one (5B/5A) of the pieces of the pair (5A, 5B) on said predetermined sector. This thus allows a rotational movement of the two parts (5A, 5B) to bring the abutment means into contact with at least a first part of the C-rail or a first part of the profile (6) or with at least one edge of an elongated window (1F, 6F, 1AF), and to bring the second part into a self-locking position with respect to the C-rail or a profile.

The or at least one of the abutment means (53,54) of said one (5B/5A) of the parts of the pair (5A, 5B) is adapted so that when the or the at least one abutment means (53,54 ) is in contact with the first part of the C-rail or the second part of the C-rail (1) or with the first part of the profile (6) or with the second part of the profile (6) or with at least one edge d an elongated window (1F, 6F, 1AF), the first part (5B) and second part (5A) of the pair (5A, 5B) can undergo between them a relative translation movement in a direction parallel to the axis of rotation (B-B), when rotating in the tightening direction and when rotating in the loosening direction.

In the clamping position, the abutment means is in contact with the first part of the C-rail or the second part of the C-rail (1) or with the first part of the profile (6) or the second part of the profile (6) or with at least one edge of an elongated window (1F, 6F, 1AF), which makes it possible to ensure better maintenance of the position of the part to be secured relative to the C-shaped rail, and this despite possible vibrations .

The connection means (5) also allows very rapid assembly, pre-maintenance and perfect connection, with the desired tightening torque of the part to be secured with respect to the rail. The operator can easily place the part to be joined in the desired location, and hold it in position while handling the tightening tool, with a predetermined minimum tightening torque.

Advantageously, the thread of the threaded portion (50F) of the rod 50 has (a) a first part which, in contact with the thread of the recess or passage (51), ensures a minimum clamping force so that a rotation of the first part ( 5B) on a given sector causes a rotation of the second part (5A) on the same given sector as long as the second part (5A) does not abut against a surface of a rail (1) or section (6), and (b ) a second part which in contact with the thread of the hollow or passage (51) does not provide the minimum clamping force.

When the threads in contact do not provide this minimum clamping force, a relative rotation between the first part (5B) and the second part (5A) is possible.

Details and advantageous particularities of embodiments are given below: - the foot (52) has an elongated shape with two parallel edges (55A, 55B) separated from each other by a distance (LAM) corresponding at 0.9 to 0.99 times the passage width (LP) of the at least one elongated window selected from the group comprising the series of elongated windows (1AF) of the core (1A), the elongated window - (1F ) defined between the returns (1BR, 1CR) of the wings (1B, 1C) and the series or series of elongated windows (6F) of the section (6).

- said other (5A / 5B) of the parts of the pair (5A, 5B) has: (*) a head (SAT) with a hollow or slot or a contour (5AT1, 5ATC) adapted to cooperate with the head of a screwing tool, and (*) the bearing face (5AI) having grooves or locking protrusions (56), to oppose loosening with an effort less than a predetermined minimum effort of said other (5A/5B ) of the parts of the pair (5A, 5B) when the latter rests on a face (41) of the metal part (4) to be secured to said C-rail (1). These protuberances 56 resting on a surface provide a tightening torque opposing the loosening, which is added to the tightening torque due to the threads.

- the metal part to be secured (4) has positioning means (45,45'} of the metal part to be secured (4) relative to the at least partially C-shaped rail (1), in particular relative to the elongated window (1AF, 1F) of the latter.Such means are advantageous for centering the connecting means or the rod with respect to a window whose width is greater than the diameter of the rod (50).These positioning means can also cooperate to increase the connection of the part (4) with the C-rail. - the metal connection means (5) is mounted on the metal part to be connected (4) so as to form a single sub-assembly whose connection means (5) cannot be separated from the metal part to be fastened (4).This makes it easier to hold the connecting means and the part to be fastened to the C-rail in position.

-the rod (50) has a non-threaded portion engaged in the passage (40) of the metal part to be secured (4), said non-threaded portion having a circular section corresponding substantially to the section of the passage (40) of the metal part to be secured (4), to substantially avoid any lateral floating of said unthreaded portion (5ONF) of the rod (50) relative to said passage (40) of the metal part to be secured (4).

wherein a portion of the flat part (53A, 54A) adjacent to said curved part (53B, 54B) forms a ratchet or cam or wedge type system with a locking force during the rotation of said one of the parts of the pair ( 5A,5B) in the tightening direction to hold the flat part (53A,54A) against the flat face of the C-rail (1) or the edge of an elongated window (1AF,1F,6F), and oppose non-maintenance of the flat part (53A, 54A) against the flat face of the C-rail (1) or the edge of an elongated window (1AF, 1F, 6F), and opposing a rotation of said one ( 5B/5A) of the parts of the pair (5A, 5B) in the loosening direction by applying a rotational force less than the locking force. This blocking system advantageously serves as a wedge or wedge to oppose relative movements between the rail and the part to be secured, once the part to be secured in the secured position. The abutment means can be centered with respect to the axis of rotation B-B of the rod 50 or can be off-center with respect to said axis, then having with respect to the axis of rotation a first portion and a second portion longer than the first portion. - The metal part to be secured (4) has a part associated with one or more inserts (47) for one or more screws and/or with one or more sleeves (48) by fluorescent drilling for one or more screws.

The core (6AM) extends against the inside faces of the returns (1BR, 1CR) so that the series of elongated windows of the core (6AM) extend at the level of the longitudinal window (1F) of the C-track (1). The 6AM core of section 6 has an inner face (61) facing the inner chamber (2). The elongated windows (6F) have a length equal to at least twice the passage width of the window (6F). and (c) a metal connection means (5) between the metal part to be secured (4) and a part of said C-shaped rail (1), with the interposition of the profile (6) adapted to slide in the interior chamber (2), to hold in position at least said metal part to be secured (4) at a predetermined location of said C-shaped rail (1), said metal connecting means (5) comprising at least one rod (50) adapted to be introduced into said passage ( 40) of said metal part (4) and at least one elongated window (1F, 1AF). The metallic connecting means (5) comprises at least one pair of cooperating parts comprising:

(a) a first part (5B) having a metal rod (50) with at least one threaded portion (50F) adapted to extend into the passage (40) of the metal part to be secured (4), said rod having a central axis B-B, and (b) a second part (5A) having a recess or a threaded passage (51) adapted to receive at least partially the threaded portion of said metal rod (50) of said first part (5B).

Said first and second parts (5A, 5B) are movable between them by a movement of relative rotation between them around the central axis of rotation (B-B) to move them (*) during a relative movement of rotation around the axis B-B in a direction of release from a clamping position securing the part to be secured 4 on a part of the C-shaped rail (1) towards a non-clamping position, in which the metal connection means (5) and the part metal (4) to be secured can at least undergo a translational movement with respect to the C-shaped rail (1), and (*) during a relative rotational movement around the axis B-B in a tightening direction between a position of non-clamping, in which the metal connecting means (5) and the metal part to be secured (4) can at least undergo a translational movement relative to the C-shaped rail (1) and the clamping position securing the metal part to fasten (4) to part of the C-rail (1).

One (5B) of the parts of the pair of parts (5A, 5B) cooperating with each other has a foot (52) with a support face (52A) intended to bear against the inner face (61) of the section (6), while the other (5A) of the parts of the pair of parts (5A, 5B) has a support face (5AI) intended to bear against one face of the metal part to be secured (4 ) to said C-rail (1). Said foot (52) is profiled to allow its introduction into the open interior chamber (2) via the longitudinal opening (1F) of the C-rail (1) and via an elongated window (6F) of the profile (6). Said foot (52) having a maximum width (LAM) less than the passage width (LP) of the elongated window (6F) and a minimum length (LOM) corresponding to at least 1.7 times the passage width (LP) .

Said one (5B) of the parts of the pair of parts (5A, 5B) comprises abutment means (53, 54) limiting the rotational movement of said foot (52) in the open inner chamber (2) between a first position of maintenance for which the abutment means (53,54) is/are in contact with at least one edge of an elongated window (6F) to oppose a rotation of said one (5B) - of said parts of the pair (5A, 5B) during a relative rotational movement between the first part (5A) and the second part (5B) of said pair in a clamping direction, and with at least a second part of the C-rail (1 ) or with at least one edge of an elongated window (1F, 6F, 1AF) to oppose rotation of said one (5B) of said parts of the pair (5A, 5B) during a relative rotational movement between the first part and the second part of the pair (5A, 5B) in a loosening direction. This makes it possible to ensure the correct position of the foot in the rail chamber, even without having a view of this foot.

The thread of the threaded portion (50F) of the rod (50) of the first part (5B) and the thread of the hollow or threaded passage (51) of the second part (5A) are adapted to ensure a minimum clamping force between them, so as to allow, until contact with the or at least one abutment means (53, 54) of said one (5B) of the parts of the pair (5A, 5B), a rotational movement of said another (5A/5B) of the parts of the pair (5A, 5B) causes said one (5B/5A) of the parts of the pair (5A, 5B) to rotate. The stop can then pass from a position of figure 6 to the position of figure 7, and vice versa.

The abutment means (53,54) of said one (5B) of the pair of pieces (5A,5B) is adapted so that when the abutment means (53,54) is in contact with an edge of an elongated window (6F), the first part (5A) and second part (5B) of the pair (5A, 5B) can undergo between them a relative translational movement in a direction parallel to the axis of rotation (B-B), when rotation in the tightening direction and during rotation in the loosening direction.

The metal part to be secured (4) has means (45) for positioning the metal part to be secured (4) relative to the at least partially C-shaped rail (1), in particular relative to the elongated window (1F) of this one. These positioning means have the form of recesses 450.451 of the plate (4) defining edges intended to match the free edges of the - returns (1BR, 1CR) of the wings of the C-shaped rail (1). The recesses have a depth corresponding substantially to the thickness of the C-rail (1), so that “n clamping position, the recesses 450.451 rest on the face of the profile (6) located in the inner chamber ( 2).

The metal connection means (5) is mounted on the metal part to be secured (4) so as to form a single subassembly of which the metal connection means (5) cannot be separated from the metal part to be secured (4 ).

The rod (50) has an unthreaded portion (5SONF) engaged in the passage (40) of the metal part to be secured (4), said unthreaded portion having a circular section corresponding substantially to the section of the passage (40) of the metal part to be secured (4), to substantially avoid any lateral floating of said non-threaded portion of the rod (50) relative to said passage (40) of the metal part to be secured (4). As shown in Figures 6 and 7, the abutment means (53,54) comprises: (*) a flat part (53A, 54A) intended to take in a first position called holding support on a longitudinal edge of an elongated window (6F) of the profile 6, and (*) a curved part (53B, 54B) adapted during a rotational movement in a clamping direction to slide along the longitudinal edge of an elongated window (6F) of the profile (6), in which a portion of the flat part (53A, 54A) adjacent to the said curved part (53B, 54B) forms a system of the ratchet or cam type with a blocking force during the rotation of the said one of the parts of the pair (5A,5B) in the tightening direction to hold the flat part (53A,54A) against the flat face of the C-rail (1) or the edge of an elongated window (1AF,1F,6F), and opposing the flat part (53A,54A) not being held against the planar face of the C-rail (1) or the edge of an elongated window (1AF,1F,6F), and opposing rotation of said one (5B/5A) of parts of the pair (5A, 5B) in the loosening direction by applying a rotational force less than the locking force.

This particular metal connection means comprises: (a) a first part (5B) having a metal rod (50) with a threaded portion (50F) with a central axis B-B and a substantially cylindrical non-threaded portion (5ONF) with a diameter ( D50), the unthreaded portion (5ONF) carrying a foot (52), said foot having a maximum width L corresponding substantially to the diameter (D50) of the unthreaded portion (5ONF) and a minimum length equal to at least 1.7 times the diameter (D50), and (b) a second part (5B) having a hollow or a threaded passage (51) with a central axis corresponding to the central axis B-B of the threaded portion (50F) of the metal rod ( 50), said hollow or passage (51) receiving and cooperating at least partially the threaded portion (50F) of said metal rod (50) of said first part (5A), said second part (5B) comprising a head (5AT) adapted to cooperate with the head of a tightening-loosening tool, said first and second parts (5A, 5B) being movable between them by a movement of relative rotation between them around the central axis (B-B) to generate a relative displacement of translation between the foot 52 and the head (5AT), for which during a relative rotational movement around the central axis B- B in a first direction, the head (5AT) and the foot (52) approach each other, while during a relative rotational movement around the central axis (B-B) in a second direction opposite to the first direction, the head (SAT) and the foot move away from each other.

Said foot (52) defines a support face (52A), while the head (5AT) - defines a support face (5AI) facing the support face (52A) of the foot (52). Said head rest face (SAT) has locking grooves or protuberances (56) when they come into contact with a surface of a support (4).

The unthreaded portion (5ONF) of the stem (50) is provided with a stop (53) (or two diametrically opposite stops with respect to the axis of rotation) - extending from the foot (52) and forming a protuberance along the cylindrical face of the non-threaded portion (5ONF), said abutment having at least one flat face (53F, 54F) substantially tangent to the cylindrical face of the non-threaded portion (5ONF) to limit the rotation of the foot (52) placed behind an elongated window, and advantageously two flat faces substantially tangent to the face - cylindrical, said two flat faces preferably being substantially perpendicular to each other.

After having placed the profile 6 in the inner chamber 2 of the C-rail, the foot 52 of the connecting means 5 is inserted into the elongated slot 6F. (see figures 1 and 2)

After a rotation of 90°, the stop 53 comes into contact with the lower edge of the window 6F. (see Figure 3) By continuing to screw part 5A onto part 5B, the SAT head is moved towards foot 52. Flat 4 is thus pushed against the returns of the flanges of the C-rail (1).

The metal profile (6) has between the longitudinal bearing portions (61,62) a groove (63G) whose bottom forms the intermediate longitudinal portion (63) with the series of elongated windows (6F). The main positioning means (45) of the metal part to be secured (4) is formed by a recess (4E) whose bottom (49) has the passage (40) for the rod (50) of the connecting means (5) , said depression (4E) having at least one inclined face adapted to cooperate with inclined sides (63F) of the groove (63G) during the introduction of the depression (4E) into the groove (63G) of the metal profile ( 6) ensuring at least contact points between the at least one inclined face (45) of the depression (4E) and the inclined sides of the groove (63G). The metal part to be secured (4) has folds forming wings (4L) adapted to cover at least partially the wings (1B, 1C) of the at least partially metal C-shaped rail (1). These folds (4L) serve as a means of — positioning (45') of part 4 on the C-shaped rail (1). A third embodiment is shown in Figures 21 to 28. As in the other embodiments, the C-rail (1) has wings (1B, 1C) with returns and a longitudinal slot (1F). The metal part (4) is a square connector to connect the C-rail (1) to another profile.

The metal connecting means (5) comprises at least one pair of cooperating parts comprising: (a) a first part (5B) having a metal rod (50) with at least one threaded portion (50F) adapted to extend in the passage (40) of the metal part to be secured (4), said rod having a central axis B-B, and

(b) a second part (5A) having a recess or a threaded passage (51) adapted to at least partially receive the threaded portion of said metal rod (50) of said first part (5B).

Said first and second parts (5A, 5B) are movable between them by a movement of relative rotation between them around the central axis of rotation (B-B) to move them (*) during a relative movement of rotation around the axis B-B in a loosening direction from a clamping position securing the part to be secured to a part of the C-shaped rail (1) towards a non-clamping position, in which the metal connection means (5) and the metal part (4) to be secured can at least undergo a translational movement relative to the C-rail (1), and (*) during a relative rotational movement around the axis B-B in a tightening direction between a position of non-clamping, in which the metal connecting means (5) and the metal part to be secured (4) can at least undergo a translational movement relative to the C-shaped rail (1) and the clamping position securing the metal part to be secured (4) on part of the C-rail (1).

The second part (5A) has the foot (52) with a support face (52A) intended to rest on the inner faces (1BRI, 1CRI) of the returns (1BR, 1CR) of the wings (1B, 1C) of the rail C-shaped (1), while the other part (5B) has a support surface (5AI) intended to bear against one face of the metal part to be secured (4) to said C-shaped rail (1).

Said foot (52) being profiled to allow its introduction into the open interior chamber (2) via the elongated window (1F) defined between the returns (1BR, 1CR) of the wings (1B, 1C), said foot (52) having a maximum width (LAM) less than the passage width (LP) of the elongated window or windows under consideration and a minimum length (LOM) corresponding to at least 1.7 times the passage width (LP).

said one (5A) of the parts of the pair of parts (5A, 5B) comprises abutment means (53, 54) limiting the rotational movement of said foot (52) in the open inner chamber (2) between a first position of maintenance for which the abutment means (53,54) are in contact respectively with the inner face of one of the flanges 1B, 1C of the C-shaped rail, to oppose rotation of said one (5A) of said parts of the pair (5A, 5B) during a relative rotational movement between the first part (5A) and the second part (5B) of said pair in a tightening direction, and with at least one other part of the wings of the C-shaped rail (1) to oppose a rotation of said one (5A) of said parts of the pair

(5A, 5B) during a relative rotational movement between the first part and the second part of the pair (5A, 5B) in a loosening direction.

The thread of the threaded portion (50F) of the rod (50) of the first part (5B) and the thread of the hollow or threaded passage (51) of the second part (5A) are adapted to ensure a minimum clamping force between them, so as to allow that, until the contact of the or at least one abutment means (53, 54) of said one (5A) of the parts of the pair (5A, 5B) with the inner face of the wings, a rotational movement of said other (5A/5B) of the parts of the pair (5A, 5B) causes a rotation of said one (5B/5A) of the parts of the pair (5A, 5B).

The abutment means (53,54) of said one (5A) of the parts of the pair (5A,5B) are adapted so that when the or at least one abutment means (53,54) is in contact with the first part of the C-rail or the second part of the C-rail (1), the first part (5A) and second part (5B) of the pair (5A, 5B) can undergo between them a relative translation movement in a parallel direction to the axis of rotation (B-B), when rotating in the tightening direction and when rotating in the loosening direction.

The rod (50) of the first part (5B) of the connecting means (5) is integral with the foot (52), while the second part (5A) of the connecting means (5) has a hollow or a threaded passage ( 51) to receive a threaded portion (50F) of the rod (50), the rod (50) being associated with a means (57) preventing the rod (50) from coming completely out of the hollow or passage (51F) of the second piece (5B) of the connecting means (50). This means is for example obtained by a plastic deformation of the free end of the rod 50, to form a bead 57.

As for the other embodiments, the rod 50 is associated with a head (5AT) adapted to cooperate with a screwing tool.

The foot 52 has two parallel edges 55A, 55B interconnected by inclined flat parts 53A, 54A (inclined with respect to the parallel edges 55A, 55B. The abutment means (53,54) of the foot 52 comprises: (*) a flat part (53A, 54A) intended to take in a first so-called holding position bearing on an inner flat face of the inner chamber (2) of the C-shaped rail (1) or on a longitudinal edge of an elongated window (1F, 1AF, 6F) of the C-rail or the profile (6), and (*) a curved part (53B, 54B) adapted during a rotational movement in a clamping direction to slide along the said inner flat face of the inner chamber or along the longitudinal edge of an elongated window (1AF,1F,6F) of the C-rail or profile (6), wherein a portion of the flat part (53A,54A) adjacent to said curved part (53B, 54B) forms a ratchet or cam-type system with a locking force during the rotation of said one of the parts of the pair (5A, 5B) in the tightening direction. age to maintain the flat part (53A, 54A) against the flat face of a wing of the C-rail (1), and to oppose the non-maintenance of the flat part (53A, 54A) against the flat face of a wing of the C-shaped rail (1), and opposing a rotation of said one (5B/5A) of the parts of the pair (5A, 5B) in the loosening direction by applying a rotational force less than the force of blockage.

The metal part to be secured (4) has a part associated with one or more inserts (47) for one or more screws and/or with one or more sleeves (48) by fluorescent drilling for one or more screws.

To facilitate the positioning of the bracket (4) with respect to the longitudinal slot (1F) of the rail (1), the part to be secured (4) has deformations 45 serving as positioning means, these deformations 45 defining suitable protuberances to come into contact with the free edges of the C-rail flange returns (1).

The embodiment of Figures 29 to 31 uses a connecting means (5) similar to that used in embodiments 1 and 12. The C-rail (1) has a web (1A) presenting a series of longitudinal windows ( 1AF). The part to be secured (4) has the shape of a profile defining a groove (4G) with a series of windows (4F). This profile (4) is similar to the profile (6) of the whole of the figure

12.

The attachment of the part (4) to the rail (1) of FIG. 29 takes place by placing opposite one another a window 4F of part 4 and a window 4F, by the introduction of the foot 52 through the windows so that the foot extends into the inner chamber 2 of the rail 1, and by screwing first to _ bring a stopper of the foot 52 into contact with at least one longitudinal edge of a window 1AF of the core 1A of the C-shaped rail (1), and then to tighten the head 51AT so that its bearing face with the locking protuberances 56 rests on the bottom of the hollow of the groove 4G.

The embodiment of Figures 32 to 34 is similar to that of Figures 29 to 31, except that the windows 1AF of the profile 1 are transverse and parallel to each other. section 4 defines a groove 4G and is therefore a C section.

Figures 37 to 42 are views of another embodiment of an assembly according to the invention similar to that of Figure 5. In this embodiment, the C-rail (1), the profile (6) the part to be secured (4) are similar to those of the embodiment of Figure 5. The connecting means (5) is itself very similar to that used in the embodiment of Figure 21. The means of connection (5) comprises: - a first part (5B) secured to the rod 50 ending in the abutment 57, this first part (5B) being identical to that of the embodiment of FIG. 21; - A second part (5A) in the form of a foot (52) with a threaded passage (51) (see Figure 26 for this reference), the threaded passage being eccentric with respect. at the foot (52). In this embodiment, the threaded portion thread (50F) of the rod (50) has: (a) a first part (adjacent to the stopper 57, part close to the free end of the rod 50) which in contact with the thread of the hollow or passage (51) ensures a minimum clamping force so that a rotation of the first part (5B) on a given sector causes a rotation of the second part (5A) on the same given sector as long as the second part (5A) does not abut against a surface of a rail (1) or a surface of a profile (6), and (b) a second part which contacts the thread of the hollow or passage (51) does not ensure the minimum clamping force, thus allowing relative rotation between the first part (5B) and the second part (5A). This relative rotation is a quasi free relative rotation for this second part.

The threaded passage (51) is eccentric with respect to the foot (52) so that the center of gravity of the foot (52) is separated from the axis B-B of the upper (50), so as to ensure with respect to the axis B-B a couple due to gravity. Other means are possible so that the center of gravity of the foot is eccentric with respect to the axis B-B of the passage for the upper (50). When the tightening force or the tightening torque between the threads is almost zero (for the second part of the upper 50), gravity allows the foot to remain in a position with its remote end (53) (forming an abutment) by contact with an inner face (6CI) pure profile (6). This then allows that during the tightening operation, the operator is assured that the foot extends into the desired position.

In the embodiment of Figures 37 to 42, the foot (52) has a length greater than the length of the window (6F) and a width less than the width (LP) of the window (6F). To introduce the foot (52) into the window (6F), the foot is placed in a plane inclined with respect to the plane of the windows (6F), to first introduce the end (53) of the foot (52) into the window (6F). (Movement indicated by the arrow F) For this introduction, the foot (52) is located adjacent to the end (57) of the rod (50), in a part where the thread of the rod (50) provides a force or a minimum tightening torque, so that any rotation of the head (51AT) of the rod (50) causes an identical rotation of the foot (52). The operator then only has to hold the head (51AT) to position in the longitudinal axis of the windows (6F) to introduce the foot (52) into the interior chamber (2) via the window (6F). After having positioned part of the foot inside the chamber (2) (which ensures that the foot (52) is in a position allowing its complete insertion into the chamber), by a slight pivoting movement of the part to secure (4), the entire foot is caused to extend into the inner chamber (2). (see figure 39) By effect of gravity the foot (52) with the rod (50) pivots so that its remote end (53) extends downwards (Rotation RR) and touches an inner underside of the profile (6 ). In this position, the connecting means ensures a - maintenance of the part to be secured on the profile (6) and on the C-rail (1). This allows the operator to properly place the parts together without having to worry about having to hold the part to be secured in his hand to prevent it from falling. When the stop (53) is in contact with a face of the profile (6), it is possible to screw the rod (50) onto the threaded passage, first with a tightening torque greater than the minimum tightening torque between the threads with the foot adjacent to the free end of the rod, to then cause the foot (52) to cooperate with the second part of the threaded rod (50).
