Definitions

  • the present invention avoids the drawbacks mentioned above.
  • the present invention also provides a device of small size and attractive appearance, the various accessories for the closure and locking of the cover being completely hidden and easily mounted.
  • the fluid-tight closure device is characterized essentially by the fact that it is constituted by the assembly:
  • the edge corresponding to the opening comprises a re-entrant portion inclined at a certain angle towards the interior and followed by another turned-back portion, that is to say directed towards the exterior and forming a V with the first part of the edge, so that the said folded arrangement of the edge of the casing forms an anti-splash arrangement for the device;
  • the fold directed towards the exterior, or turned-back portion being directed towards the angle of the edge of th cover, while an appropriate joint is arranged in the said angle and ensures the fluid-tightness of the device.
  • the joint of the cover is composed of a flexible or semirigid plastic material or of rubber or of any other suitable material, and has a quadrangular or triangular section, the apex of the triangle or an angle of the rectangle respectively coinciding with the inner edge of the cover.
  • the present invention has also for its object any casing, box, switchboard and the like equipped with a fluid-tight closure device such as specified above.
  • FIG. 1 is a front view of one possible form of construction of a protection casing provided with an edge according to the invention.
  • FIG. 2 is a half-section taken along the line aa of FIG. 1, in which there has also been shown a preferred arrangement of the cover provided with a fluid-tight joint according to the invention, with respect to the casing.
  • FIG. 3 is a cross-section to a smaller scale, taken along the line b-b of FIG. 2, showing an advantageous arrangement of the sealing joint in the interior of the cover.
  • FIG. 4 is a partial cross-section to a larger scale of one preferred form of construction of the edge of the casing, as shown in FIGS. 1 and 2.
  • FIGS. 1 and 2 there has been shown by way of example a casing or box 1 provided with a fluidtight closure device according to the invention.
  • the edge corresponding to the opening of the casing 1 comprises a re-entrant portion 2 inclined at a certain angle towards the interior of the casing and followed by a turned-back portion 3, that is to say directed towards the exterior.
  • the metal sheet thus folded forms a V which constitutes an excellent anti-splash device while the acute angle of the said V forms a gutter.
  • the cover 4 shown very diagrammatically by way of example in FIG. 2, and which generally has a rounded form on its upper part, fits over the two folds 2 and 3 of the edge of the easing 1 in such manner that the turned-back portion 3 is directed substantially in the direction of the edge 5 of the cover 4,
  • a sealing joint 6 is arranged in the angle 5 of the edge of the cover 4.
  • This joint is made of flexible rubber or plastic material or of any other appropriate material. It may advantageously be given a rectangular section such as shown in FIGS. 2 and 3, in full lines and in cross-section.
  • the said joint may have a greater width on the upper and lower edges S'a and 8b respectively and on the edge 9a than on the edge 9'b which corresponds to the articulation of the cover.
  • the joint on the side 9b on which the hinges are located can be arranged on edge, that is to say with the supporting face against the edge 3 placed parallel to the fold of the cover, since the pressure force of the edge 3 is more particularly applied perpendicular to the said fold.
  • This same joint 6 can also have a triangular section 7, as has been shown in dotted lines on FIG. 2.
  • FIGS. 1 and 2 there has been shown a sheet metal plate 12 fixed against the bottom 13 of the casing 1 provided with threaded bolts 14, it being understood that this arrangement is only given by way of example and does not form the object of the present invention. Corresponding openings 15 permit the passage of the bolts 14.
  • FIG. 4 there has been shown in cross-section in FIG. 4 an arrangement of the edge of the opening of the casing 1, such that the reentrant portion 2 forms an angle of 30 with the corresponding wall of the casing 1, while the angle which it forms with the turned-back portion 3 is comprised between 75 and 90.
  • the two folds 2 and 3 on the edge of the casing 1 which form a V are coupled together by a rounded portion 16 forming a gutter.
  • the method of closure of the cover of the casing or box can be effected by any known means.
  • the fluid-tight closure device according to the invention may be employed for the protection of metal-clad switchboards.
  • a casing open at least on one face, and the edge of which corresponding to said opening face comprises a re-entrant portion inclined at a certain angle towards the interior, followed by a turned-back portion towards the exterior and forming a V-shaped gutter with said first portion;
  • a fluid-tight joint disposed in the angle of the corner edge of the cover
  • a casing open on at least one face and in which the edge corresponding to said opening face comprises a reentrant portion inclined towards the interior at a certain angle, followed by a portion turned-back towards the exterior and forming a V-shaped gutter with said first portion, said gutter forming an angle of 30 with the plane of the opening surface of said casing and an angle comprised between and with said portion turned back towards the exterior;
