Definitions

  • the present invention relates to a cylinder-operated opening damper.
  • the invention relates to a shock absorber with an external opening cylinder for shutters.
  • Known cylinder-type door dampers are interior door dampers. They are defined by a fluid leak-proof chamber and a rod inserted into the rod chamber provided with a blocking element and a ring and having; a first and a second valve each provided with channels; the damper comprising a rolling assembly with rollers allowing rolling and guiding on the lower part of a rail. This assembly forms a cylinder.
  • the fluid is oil.
  • a damper must solve the technical problem of overcoming four additional technical hurdles to the basic functions such as damping, braking or fixing so that dampers or brakes can function by damping and braking the travel of a flap.
  • the first difficulty arises from the large variations in temperature and humidity encountered outside compared to a relative constancy of temperature inside. It must be expected that temperatures can vary from -25° in winter to +60°. When the shutters are placed under a casing, the radiation resulting from this casing increases the temperature further. Consequently, the shutters will experience temperatures higher than the outside temperature itself.
  • the document US 2013/160240 A1 refers to a device applied to interior doors.
  • the jack known by the document US 2013/160240 A1 does not seek these characteristics at all. In fact, it applies to an interior door that does not need to withstand the constraints that exterior openings, namely shutters, undergo.
  • This known cylinder works with a spring or a compressible fluid. Therefore, it is a medium with elasticity.
  • the present invention aims to solve this technical problem and to prevent a shutter damper from being stopped or degraded in its operation by the above obstacle which would not be overcome.
  • the opening damper with cylinder this cylinder being in accordance with the standardization of shutters the opening being external, in which the fluid of the cylinder is inert with regard to the temperature, making the damper suitable for temperatures from -25 to +60 ° C to maintain the shutter damper functionality outside.
  • the rod of the gas cylinder inert with respect to the temperature forms a shock absorber and a shutter brake.
  • the shock absorber comprises a fixed means cooperating with a movable part carrying said rod.
  • the shock absorber actuated by the rod is fixed in a hollow rail.
  • the invention also relates to the use of a damper for a shutter with a cylinder in accordance with the above, the shutter being external, in which the fluid of the cylinder is inert with respect to the temperature such as nitrogen or thermo-constant oil, making the damper suitable for temperatures from -25 to +60°C to maintain the shutter damping functionality on the outside.
  • the fluid of the cylinder is inert with respect to the temperature such as nitrogen or thermo-constant oil, making the damper suitable for temperatures from -25 to +60°C to maintain the shutter damping functionality on the outside.
  • This allows it to withstand temperature variations and to be suitable for cold regions typically in assembly as well as hot ones for example in the South; this with a view to assisting in the handling of shutters.
  • the opening damper system according to the invention is a system which withstands variations in external temperatures.
  • the device according to the invention aims to withstand outside temperatures. This is why the dampers of openings of the technique are limited to doors which are interior openings because they do not respond to this exterior problem.
  • the cylinder comprises a constant thermo fluid and of dimensions adapted to the shutters (exterior openings because for temperatures from -25 to +60°C, i.e. exterior temperatures which can be very different depending on the location, high mountains or Midi for example)
  • the aim of the invention is to provide a shutter operating assistance device equipped with a gas cylinder inert with respect to the temperature moving a hook to the trigger actuating the cylinder rod which forms a shock absorber and shutter brake.
  • a shock absorber cylinder 1 is shown in vertical section. figure 1 , a leak-proof chamber 1a of the piston 1b.
  • First and second non-return valves 1c and 1d are mounted on the outer circumference of the rod 1e of the piston 1b on either side of a groove 1f of said rod 1e.
  • This assembly forms the channels 1g which pass into the first and second valves 1c, 1d and via the groove 1f forms a baffle allowing the movement of the fluid represented by arrows.
  • the valves and channels are internal shapes of the piston 1b.
  • the piston 1b is of a size respecting the standardization of exterior shutters.
  • the cylinder 1 is made of a leak-proof chamber 1a filled with inert fluid. This fluid is typically nitrogen. It can be thermo-constant oil.
  • the shutter damper is a damper for exteriors. Its parts are made of plastic or aluminum which have a high dimensional stability even when temperatures vary.
  • the damper shown comprises the cylinder 1 with a piston 1b actuating under the effect of the pressure of the inert fluid a hook via a guide.
  • a movable part 2 allows the movement.
  • the movable part is in a larger device comprising a fixed part relative to the wall not shown.
  • This fixed part comprises a stop 3 of dimensions cooperating with the inner part of a hollow rail 4.
  • a flat extension 5 is fixed at one of its ends on the upper surface of the stop 3. This extension 5 extends above the movable part here, a carriage 6.
  • a trigger 7 is fixed to the other end of the extension 5.
  • the stop 3 has on its lateral face located under the extension 5 a damping means 3b, in the figure this means is shown as being a part of the stop 3 made of flexible material which stops the movable part 2 of the shutter damper when the latter reaches the end of its travel.
  • the stop 3 fulfills its function of stopping the movement.
  • the stop 3 has in the lower part a base 3c which matches the lower opening of a rail and by two respective shoulders comes to rest on the two lower flat parts of the rail 4 which border its lower opening 8. Screws 3a come to tighten the roof of the rail 4. This tightening is transmitted to the base 3c.
  • the base fulfills an immobilization function and forms a fixed point.
  • the movable carriage 2 is placed in the hollow rail 4, the combination of the shock absorber cooperating with the fixed means forming the shutter operation assistance device which is constrained in the rail 4.
  • the shutter operation assistance device forms a shock absorber and shutter brake. It comprises the hollow rail 4 containing a means fixed relative to the wall, comprising the stop 3 linked to the trigger 7 by an extension 5, said rail also containing a carriage 6 equipped with the jack 1.
  • the shock absorber is made up of several parts, each of which must resist and function consistently. This problem had to be solved.
  • the shock absorber is composed of parts made of materials that resist these temperature variations, such as plastics and/or aluminum. Also, the piston gas does not vary in density when the temperature goes from -25 to +60.
  • the invention also relates to the use of the opening damper with a cylinder 1 forming a carriage 6 carrying a piston 1b with inert fluid, the opening being external, in which the inert fluid with respect to the temperature of the cylinder 1 makes the damper suitable for temperatures from -25 to +60°C to maintain the shutter “damper” functionality on the outside.
