Definitions

  • the present invention relates to a new automatic seal liftable installed at the bottom of the doors to improve watertightness.
  • the present invention provides a new control device for an automatic door seal with vertical translation, in which the stress exerted on the seal in its working position is independent of the device control means.
  • the present invention relates to a seal for the bottom of the leaf. door, movable in rotation relative to a door, of the type comprising a gasket mounted on a support, a rail mounted fixed on the leaf, at least two rods, each rod is articulated at one end on an upper axis secured to the rail and by the other end on a lower axis secured to the support, characterized in that it further comprises a movable member which is connected at one end to a return spring supported on the rail and at the other end with a strap which is fixed to the frame, so that according to the movement of the movable member said strap and said return spring respectively command the raising and lowering of said seal.
  • the automatic translation joint control device vertical uses a flexible elastomer seal attached to a rod rigid articulated using at least two rods inside a U-shaped rail, at least one of the links being controlled by a sliding drawer and secured on the one hand to a return spring and on the other hand to a strap traction whose other end can be fixed to the door opening by the by means of a cam on which said strap is partially wound when opening the door, causing traction on the drawer and retraction of the seal in its raised position.
  • Figure 1 is a schematic front view of the entire seal automatic installed on the door leaf, the seal being in its position identified.
  • Figure 2 shows the same view as in Figure 1, the seal being in the lowered position.
  • Figure 3 shows a cross section of the mechanism according to A-A 'in Figure 1.
  • Figures 4a and 4b are front and plan views, respectively. of the system for fixing the end of the traction strap by means of a cam on the door frame.
  • Figures 5a and 5b are front and plan views, respectively. of the strap fastening system in the case of an overlapping door.
  • Figure 6 is a schematic front view of a door.
  • the automatic seal according to the invention is intended to equip a bottom leaf 1 which is articulated on a door 2 by means of hinges or hinges 3 (figure 6).
  • the automatic seal according to the invention and designated as a whole by reference 4, includes a seal 5 made of flexible elastomer, a rod of rigid support 6 on which the flexible seal 5 is mounted, a retaining rail 7, inverted U-shaped and fixed on the lower part of leaf 1, and at least two links 8 and 8a, preferably three links, two of which 8 are provided at proximity of the lateral sides of the leaf, the third 8a being disposed between the two lateral links 8, each link being articulated at one end on an upper axis 9, 9a integral with the retaining rail 7, and at the other end on a lower axis 10, 10a secured to the rigid support 6 of flexible joint 5.
  • the control means controls the position of one 8a connecting rods by means of a drawer 11 which moves horizontally, parallel to the retaining rail 7.
  • the drawer 11 is guided, on the one hand, by the rail 7 on which it is supported and, on the other hand, by the upper axis 9a of the controlled link 8a on which it can move thanks to a first light 12 or a notch in the drawer 11, parallel to the rail 7.
  • the movement of the link 8a controlled by the sliding of the drawer 11 is obtained by means of an intermediate axis 13 secured to the link 8a which cooperates with a second light 14 made in the drawer 11.
  • the light 14 comprises a first part or zone 15 parallel to the direction of translation of the drawer and a second part or zone 16 inclined relative to the translation axis: when the intermediate axis 13 secured to the link 8a is in the first zone 15 of the light 14, the link 8a maintains the seal 5 in a raised position.
  • the sliding of the intermediate axis 13 in the second zone 16 of the light 14 drives a rotation of the link 8a and the lowering of the seal 5.
  • the translation of the drawer 11 is controlled by, on the one hand, the action of a return spring 17 which is supported on the retaining rail 7 and, on the other hand, a strap or braid flexible traction 18.
  • the spring 17 tends to return the drawer 11 in a position in which the seal 5 is lowered while the traction of the strap 18, which opposes the action of the spring 17, tends to pull the drawer 11 in a position in which the seal is raised ( Figures 1 and 2).
  • the entire mechanism is generally covered by a protective cover 20 made of plastic or metal.
  • the entire device is held on the door by means of screws 21 which is preferably fixed inside the hollow axes 9, 9a, or by means an adhesive (Figure 3).
  • the length and the shape of the lights 12 and 14 of the drawer 11, as well as the offset of the cam 19 are particularly important to define the different parameters of the joint movement: in particular the cam 19 must be profiled so that traction is exerted on the strap 18 from that the leaf 7 of the door leaves its closed position, and the inclined zone 16 of the light 14 must be oriented so as to raise quickly and immediately the ordered link 8a.
  • FIGs 4a to 5b show the mounting diagram of the seal automatic on the leaf 1 of the door, and of the control cam 19 which must be fixed to the frame 2 of the door supporting the hinges 3.
  • FIG. 4a represents the assembly seen in plan in the case of a flush flat door 22 fitted with the automatic seal according to the invention.
  • the strap 18 is pinched under cam 19 held by screws 23 on the upright 24 supporting the hinges 25.
  • Figure 4b shows the previous assembly seen from the front.
  • FIGS. 5a and 5b respectively represent the plan views and front view of the device mounting in the case of an overlapping door.
  • seal 5 is made of flexible elastomer such as for example a nitrile rubber, EPDM or silicone;
  • the support 6 and the rail 7 are made of rigid material such as a aluminium section ;
  • the links 8, 8a can be made of synthetic material rigid or aluminum,
  • drawer 11 can be steel or nylon,
  • the spring 17 is preferably made of steel (one could also use a strip stretchy rubber),
  • the strap 18 which must be flexible and inextensible, is for example in braided polypropylene,
  • the cam 19 is made of rigid material such as for example Nylon, ABS or aluminum.
  • the automatic seal according to the invention has the advantage, by comparison with the known devices of the prior art, to be in its position lowered while it is at rest, i.e. when the strap does not undergo traction and when the spring is in its minimum stress: this advantage is of significant importance because the seal can be mounted on the door while that it is closed: just present and press the seal on the floor then fix the rail using screws; the strap is then pinched under very low tension, between the cam and the fixed amount of the door on the hinge side and installation is done without the need to make any adjustments or take measures.
  • ordering the device requires a simple connection on the hinge side of the door and that no accessories protrudes from the lock side of the door leaf.
  • the device offers no resistance to closing the door. He is even possible, if this function is sought, to obtain a couple of door closing reminder by adjusting the spring force and the shape of the cam of the device described above.
  • the automatic door bottom seal according to the invention finds its application mainly in buildings, where, by removing currents air passing under the doors, it improves comfort and saves Energy.
