Definitions

  • the main object of the present invention is to present a soundproofing door which combines both lightness and efficiency.
  • the example given in the following description makes it possible to obtain a damping of the order of 50 dB and another more sophisticated embodiment can go up to 60 dB. It should be noted that these characteristics are obtained for a door weight much lower than the average of around 1 ton.
  • Another object of the present invention is to present a soundproofing door which also has fire-fighting properties. Also in terms of security, the soundproofing door of the present invention is equipped with a quick opening device by anti-panic button.
  • the present invention relates to a soundproofing door intended for example to close test chambers, and / or soundproof enclosures around noisy devices.
  • the soundproofing door of the present invention provides a solution to these problems by improving the characteristics also linked to a reduction in weight.
  • the soundproofing door 1 also comprises hinge hinges 3 which connect the frame 2 and the leaf 4 of the door 1. In the example chosen, two hinges are sufficient, given the modest weight of the embodiment presented.
  • FIG. 2 represents a preferred embodiment of the invention in section view.
  • the frame 2 is firstly formed of a support profile 7 intended to be fixed to the enclosure. This U-shaped profile 7 is extremely rigid and ensures the fixing of the door on the enclosure.
  • the frame 2 also includes a peripheral support plate 8 held by two angles 9 and 10 on the profile 7. It is on this sheet 8 that the hinges 3 are fixed and it will also serve as a support plane for the seals described later.
  • the door frame 2 also consists of a frame 11 formed by an assembly of tubular profiles of square section in the example chosen. This frame 11 will also serve as a support for the second seal described later.
  • leaf 4 of door 1 has the following structure: a rigid external sheet 12, a sound insulation material 13, a central sheet 14 elastically mounted, a sound insulation material 15 and finally a rigid external sheet 16 as shown in FIG. 2.
  • the door 1 is compartmentalized thanks to the presence of the central sheet 14 which makes it possible to define the two compartments 37-38 in which the insulating materials 13 and 15 are placed respectively.
  • the flexible mounting of the central sheet 14 makes it possible to respect the integrity of the insulation properties of each of the materials 13 and 15. This is an advantageous advantage since, unlike previous embodiments in which the central sheet which served to compartmentalize the door was rigidly mounted and where a harmful interference between damping, with flexible mounting we obtain a combination of sound insulation properties. This makes it possible to cover a wide spectrum of attenuated frequencies with a relatively reduced thickness of insulating material. On a practical level, it is possible, for example, to use a diaphragm to support the central sheet 14 or more simply to use the stuffings 13 and 15 of insulating material to ensure proper maintenance of the central sheet 14.
  • an insulator based on glass wool the density of which is 70 k / m3, can be used to fill compartment 37 and a wool of glass with a density of 100 k / m3 to fill compartment 38.
  • the respective volumes of the compartments 37 and 38 may be different and in the example chosen, the low density insulating material 13 occupies a volume twice that of the high density insulation material 15.
  • the edges of the central sheet 14 may for example be slightly spaced from the periphery of the door to avoid contact or simply be applied against this periphery without rigid fixing.
  • the periphery of the leaf 4 of the door 1 is formed from a sheet metal profile 17, the interior of which is filled with insulating material 18.
  • the edges of the door are formed from a perforated sheet 19 whose positioning with respect to profile 17 is adjustable. This makes it possible to reduce the spacing between the leaf 4 and the frame 2. Thus, the sound leaks are reduced and the presence of the holes in the perforated sheet 19 also makes it possible to absorb the sounds passing through the existing interval.
  • outside edge 20 of the door 1 that is to say opposite the hinges 3, will preferably be inclined as shown in FIG. 2.
  • This bevelled exterior shape makes it possible to strengthen the sound insulation. reducing the interval between the edge 20 and the sheet 8 while taking into account the relatively large thickness of the door.
  • the invention recommends the use of peripheral seals, for example made of cell neoprene closed, the first 21 of which is interposed between the rigid outer sheet 16 and the frame profile 8 as illustrated in FIG. 2.
  • the second seal 22 is disposed between the second rigid outer sheet 12 and the frame profile 11.
  • the soundproofing door as described provides up to approximately 51 dB of attenuation of noises over a wide frequency band for a door weight ranging from 250 kg to 1 ton depending on the dimensions.
  • the leaf 4 of door 1 comprises the following structure: a rigid external sheet 12 identical to the previous one, likewise with regard to the first compartment 37 filled with insulating material on the other hand this time there are interposed two central sheets 23 and 24 separated by an air gap 25.
  • the rest of the door remains identical namely a second compartment 38 containing insulating material and a rigid external sheet 16.
  • all the faces of the walls located inside the leaf 4 of the door 1 will be covered by a layer of bitumen 26 of high density which very improves noticeably reduced noise.
  • the central sheets 23 and 24 are separated by spacer pads 27. These central sheets 23 and 24 are not fixed and are mounted freely inside the door 1. It would of course be possible to imagine the use of several compartments separated by different central sheets, at least some of which are freely mounted.
  • this comprises an operating lever 6 articulated around a control axis 28 as shown in FIG. 3.
  • the rotation of the control lever 6 can be operated directly or by the an anti-panic push button 29, the axis of which passes through the door to come to bear against the lever 6.
  • FIG. 4 shows the locking mechanism 5 proper.
  • the control pin 28 pivots in a pin 29 fixed on the external sheet 16.
  • a lever 30 fixed on the control pin 28 is connected to a chain 31, the end of which is connected to the latch pin 32.
  • This latch 32 slides freely in a support 33 and is involved in the extended position by means of a spring 34.
  • a nut 35 limits the travel of the latch 32 in the extended position.
  • the operating axis 28 When using the lever arm 6, the operating axis 28 is maneuvered, the lever 30 is caused to rotate, which drives the chain 31 and pulls the latch 32 to release the locking system. Apart from the action on the lever 6, the spring 34 ensures the return of the latch 32 in the locked position.
  • the assembly is covered by a casing 36.
  • the door 1 receives a double locking system 5 which allows it to withstand external pressures of the order of 750 kg / m2. Given the constraints encountered and the weight of the door, it is necessary to use a specific locking system.
