Description

PROFILE HANGER WITH SIDE GROOVES FOR COVER STRUCTURE

discoverable

  The present invention relates to discoverable roof structures, that is to say in which panels forming the cover can slide relative to each other. It relates more particularly to a profile, adapted for such structures, which has superposed lateral grooves for the positioning of the cover plates and their sliding. The present invention applies in particular to the field of sunroof swimming pools and light constructions of this type, some of whose structural elements are arches

arched vaults.

  The document FR is known. A. 2.599.118 a profile specially adapted for the manufacture of shelter frames, in particular for covering pools or greenhouses. It is a tubular section, with a stiffening core and a peripheral wall of generally rounded shape, which is provided with lines of least resistance so as to delimit cut strips which, once removed, define rebates for the passage of the cover plates. The stiffening soul is a body

hollow section rectangular.

  Document FR.A.2.627.530 discloses a section intended for constituting arches for a revealable roof structure. It is a tubular curved section consisting of a central carrier body, which carries, on each side and perpendicularly to its central carrier body and the vertical axis of symmetry of the profile1 of the lateral fins which are arranged at one above others and which delimit the

  lateral sliding grooves of the cover plates.

  The profile described in this document FR.A.2.627.530 is of a

  simpler realization than that of FR.A.2.599.118.

  However according to the applicant, it has several disadvantages: it is not possible to easily ensure the bridging between two adjacent hoops; in its tubular version, there is a risk of twisting of the central carrier body; in its version

  U-shaped profile, there is very high risk of deformation.

  The aim set by the applicant is to propose a section of the type described in document FR.A.2.627.530, in that it comprises a central carrier body and several superposed sets of two symmetrical lateral wings 1 'a the other relative to the central carrier body, and forming a groove for a cover plate, but which overcomes the aforementioned drawbacks. According to the invention, the central carrier body is a solid body split in its lower part, fork-shaped, whose two legs are symmetrical with respect to the plane passing through the upper part of said solid body; in addition the profile of the invention comprises: a) at least four overlapping sets of two fins, two at the top and two at the split lower part of the central body, b) two side hollow bodies of a alone with the central body, each being formed respectively by the two superimposed wings of the two median sets and one face of

  junction connecting the ends of the two said fins.

  It will be understood that the profile in its basic version with four sets of two fins comprises on either side of the central carrier body only two superposed grooves, each groove being delimited by an outer face of a hollow body.

  side and the wing that faces him.

  The resistance to twisting of the profile is given by the solid body. The hollow bodies improve the stiffening of the entire profile. The lower groove of the profile, consisting in the recess between the two legs of the lower part split of the central body, allows the placement of panels

  vertical closing the ends of the structure.

  Two adjacent arches made using the profile of the invention, can easily be fixed and kept at a distance from each other, by means of a spacer passing to

  through the two hollow bodies of each of the arches.

  Advantageously, the lower groove of the profile serves as a housing for a fixing screw passing through the upper part of the solid body and said spacer; in this case, the profile preferably comprises a closure part, to close the throat

  lower, so as to go invisible this fixing screw.

  Preferably the split lower part of the solid body has substantially the same height as the upper part. This brings a

  greater reliability when bending.

  Preferably the junction face of each hollow body is parallel to the vertical plane of symmetry of the profile and is substantially in alignment with the free ends of the other fins. Preferably the cross section of the throat between

  two jambs is of rectangular section.

  In order to increase the mechanical strength of the profile and to provide the solid carrier body with additional stiffening, the hollow bodies preferably have a cross-section

  interior in the shape of an inverted cradle.

  Advantageously, at least the two fins forming the underside of the hollow bodies comprise over their entire length, a groove capable of serving as a housing for a joint. This seal makes it possible to attenuate the vibrations of the cover plates which are mounted in the lower grooves formed by the two

  set of overlapping wings of the lower part of the profile.

  Preferably, the upper edge of the central body protrudes relative to the plane of the two fins of the upper set of the upper part of the profile. This edge provides a better seal when performing the assembly of two superimposed sections. In this case the transverse groove between the two legs of the upper profile being provided with a sealing flap, the upper edge of the central body of the lower profile cooperates with said flap to ensure a

  better seal of the whole.

  Other features and advantages of the profile of

  the invention will emerge from the following description of two modes

  particular embodiments of a profile with solid carrier body, fork-shaped, and two lateral hollow bodies, given with reference to the accompanying drawings, in which: - Figure 1 is a partial perspective view of a profile whose hollow body have a substantially rectangular inner cross-section, and FIG. 2 is a partial perspective view of a profile whose hollow body has an internal cross-section in

cradle shape reversed.

  The profile of the invention is intended to constitute a

  hoop for revealable roof structure.

  The perspective view of FIG. 1 shows the different elements of a first particular embodiment of this section, which clearly appear in section.

cross.

  According to this cross section the profile 1 has a solid carrier body 2, in two parts: an upper part and a lower part, in consideration of the median plane BB 'perpendicular

  in the vertical plane AA 'of symmetry of the profile.

  In the upper part, the solid body is a plate having

  a thickness E, placed along the plane of symmetry AA '.

  At the median plane BB ', the plate 3 divides into two branches 4 and 5 which move away from the plane AA', then continue vertically in the lower part in two legs 6.7 parallel and symmetrical with respect to the plane AAI . These two legs have a thickness e, substantially half of E, and

define a vertical groove 8.

  The profile 1 also comprises four overlapping sets 9,10,11,12 of two fins disposed on either side of the solid carrier body 2, and symmetrical to each other with respect to the plane AA '. The set 9 consisting of the fins 9a and 9b and the set 10 consisting of the fins 10a and 10b are located at the plate 3 in the upper part of the carrier body 2. The game 11 consists of the two fins 11a and 11b and the game 12 constituted two wings 12a and 12b are located at the two legs 6 and 7

  of the lower part of the carrier body 2.

  The two superposed median wings 10a, 11a meet on a junction face 13a which is, in the illustrated example, parallel to the plane of symmetry AA 'and substantially in alignment with the two free ends 9'a and 12'a. two other fins 9a, 12a. The two median wings have, 11a, the corresponding junction face 13a and the portion of the carrier body 2 located between the two medial fins 10a, 11a form a hollow lateral body 14a. This hollow body 14a has an inner cross section of substantially rectangular shape, except the concavity corresponding to the recess

  following branch 5 in the median plane BB 'and the jamb 7.

  Symmetrically with respect to the plane AA ', the two superimposed median wings 10b, 11b, the corresponding junction face 13b and the part of the carrier body 2 situated between the two median fins 10b and 11b form a lateral body

hollow 14b.

  In a specific embodiment, of course not limited to, it was a metal profile in an aluminum alloy: the thickness E of the solid plate 3 was 5 mm, that of the legs 6.7 of 2, 5 mm; the distance d between the two legs 6.7 was 20 mm; the total height H of the profile 1

  was 100 mm, the plane BB 'being just median.

  As clearly shown in the figure, it is understood that, due to the lateral recess of the branches 4,5 in the plane BB ', the fins 9a, 9b, 10a, 10b of the upper part have a

  surface greater than those 11a, 11b, 12a, 12b of the lower part.

  In the constitution of arches for discoverable roof structures, the section 1 is previously bent to give it the proper curvature, knowing that generally a hoop is formed by the assembly of two curved sections each forming a half-hoop. To do this, two connecting sleeves are used which are placed inside the two hollow bodies 14a and 14b of the two sections to be assembled, such as

  so that they are positioned astride the two profiles.

  It is also possible to make a hoop using a single section of the invention, bent to give it the proper curvature. In addition, the arches may be of various shapes, and in particular be in the form of a half-ellipse, whose major axis would coincide with the vertical axis of symmetry of the arch. In this case, we obtain a gain in height

  compared to a hoop in the shape of a semicircle.

  The lateral hollow bodies 14a and 14b have several functions: an assembly function, as described above, of several sections to form a unitary arch; a ground fastening function, in which the hollow bodies are fitted on a fastener to the ground and fixed thereto by screws passing through the junction face facing said fastening part of the ground. They also have an important role in the mechanical strength of the profile, bringing to the solid carrier body

a complementary stiffening.

  In the case of a structure with a convertible cover having arches made using the profile of the invention, each arch is fixed and kept at a distance from the adjacent two or two arches, with the aid of a spacer passing through the two hollow bodies of the profile. In this case, the fixing of the arch on the spacer can advantageously be achieved by means of a single fixing screw (not shown) which passes through the upper part of the solid body 2 and said spacer, and which is located in the lower groove 8,

  corresponding to the obvious between the two stretches 6, 7.

  Inside the groove 8, and by the same the fixing screw is

  visible from the inside of the structure constituted by the arches.

  In order to mask this fixing screw, the profile of the invention preferably comprises a closure piece 18, for closing the groove 8. This closure piece, which is for example snap-on, allows to give a decorative finish to the profile . The groove 8 may also serve as housing either to the vertical panel closing the structural end or to a rubber sealing flap in the case of two superposed arches. This last case can occur in particular when the structure is of the telescopic type, that is to say when a first set of two arches supporting cover plates can move relative to a second set of arches and plates, longitudinally with respect to the general direction of the structure, and to be embedded in this second set. The rubber flap, held in the groove 8 of the profiles of the second set,

  goes down to the level of the first set and makes the seal.

  To further improve this seal, the upper edge 3a of the plate 3 forming the upper part of the central carrier body 2 of the profile of the invention protrudes from the plane of the two upper fins 9a and 9b. In this way, the upper edge of the first assembly cooperates with the rubber flap which is held in the groove 8 of the profiles of the second set,

to improve the seal.

  The ends 6a, 7a of the legs 6, 7 of the section 1 are advantageously slightly curved towards the inside of the groove 8, so as to ensure a certain blocking of the rubber flap, and to prevent it from coming out. of throat 8 during

  possible friction against the first set.

  The presence of the groove 8 has a significant advantage, when bending the profile 1: since it is located in the lower part of the profile, facing the inner side of the arch and along the axis of symmetry of the profile , it turns out that the

  bending has a very high reliability.

  The profile 1 as just described comprises on the one hand two grooves 15a and 15b symmetrical to each other with respect to the axis AA ', and delimited by the two upper fins 9a and 9b and the two fins 10a and 10b forming the upper face of the hollow bodies 14a and 14b, and secondly two lower grooves 16a and 16b also symmetrical to each other with respect to the plane AA ', and defined by the two wings lower 12a and 12b, and by the two fins 11a and 1b forming the underside of the hollow body 14a and 14b. The profile 1 can therefore receive four cover plates, generally made of transparent plastic, at the rate of one

cover plate by groove.

  Generally, in the illustrated case of a profile with four grooves, the cover plates inserted in the two upper grooves 15a, 15b and those inserted in both

  lower grooves 16a and 16b are slidably mounted.

  FIG. 2 shows a profile 1 'making it possible to illustrate a second particular embodiment of the profile of the invention. For the sake of clarity, the elements common to the two sections 1 and 1 'of Figures 1 and 2 have the same references. This profile 1 'differs essentially from the profile 1 in that on the one hand the hollow body 14a and 14b have an inverted cradle-shaped inner cross section, and on the other hand that the height of the groove 8 formed by the two legs 6 and 7 is less than half the height H of the profile. In other words, the profile comprises an upper part and a lower part, which are delimited by the plane CC ', and which are not equal. In addition, contrary to the profile 1, the thickness of the legs 6 and 7 is substantially equal to the thickness of the solid plate 3.The inverted cradle shape of the hollow bodies 14a and 14b makes it possible to increase the resistance

mechanical profile.

  Those skilled in the art may, without departing from the scope of the invention, adapt the profile of the invention, by modifying the internal cross section of the hollow bodies, or by varying the height of the legs 6 and 7 relative to the

total height of the profile.

  Applicant has noticed that the plates which were slidably mounted within the two lower grooves 16a and 16b of the profile 1 of Fig. 1 tended to vibrate easily, causing parasitic noise at the section. To overcome this drawback, the fins 11a and 11b forming the underside of the hollow bodies 14a and 14b are respectively provided with a groove 17a and 17b making the entire length of the hollow body, and intended to receive a seal. This seal has the function of damping any vibrations of the plates mounted in the lower grooves 16a and 16b of the profile 1 '. Preferably, in order not to hinder the sliding of the plates which are mounted inside the two lower grooves 16a and 16b, a felt seal is used. In the case of the profile 1 ', advantageously the additional material is used in the lower corners of the hollow bodies 14a and 14b, which is due to the inverted cradle shape of the internal cross-section of these hollow bodies, to practice the

grooves 17a and 17b.

  The invention is not limited to the two embodiments which have been described by way of non-exhaustive examples. In particular it is possible to produce profiles with more than four lateral grooves by having other fins superimposed at the level of the upper part.

  either of the lower part of the solid carrier body.
