Definitions

  • the present invention relates to a door closer mechanism intended to ensure a regulated and automatic closing of the doors.
  • door closer mechanisms there are two types of door closer mechanisms already known, one type using a piston which moves in a chamber filled with oil and the other type using an internal element which turns in a bowl filled with oil. 'a viscous eraser.
  • the first type of door closer requires tight tolerances and is therefore expensive. However, it can be adjustable and allow adjustment of the closing speed.
  • the second type of door closer is less expensive but is generally not adjustable and works even when the door is opened; he thus opposes the free movement of the latter.
  • the object of the invention is to provide a door closing mechanism using rotary damping which only comes into play in the direction of closing the door and which is also adjustable.
  • This invention in fact relates to a door closer mechanism comprising a housing axially traversed by a shaft, these two elements being able to rotate relative to each other, and being intended to be coupled one to the door by means of an articulated linkage, and the other to the leaf of the door, and a cylindrical rotor delimiting inside the housing, an annular chamber which is filled with a fluid for damping the movement of the door , which further comprises, between the shaft and the c y l i ndreu n clutch which slips to allow their relative rotation when the door opens, but makes them integral in rotation when the shaft rotates in the closing direction of the door, and, at the ends of the damping chamber, two helical seals in opposite directions which discharge the damping fluid towards the central part of the chamber during the rotation of the cylinder.
  • the helical seals are constituted by helical threads formed on the external surface of the cylinder, either in direct engagement with the unthreaded internal face of the housing, or in engagement with bearing rings housed in recesses provided in the internal face of the housing.
  • the two threads respectively on the right and on the left, are such that, during the closing of the door, they push back the damping fluid in the annular space which separates them so that this fluid slows down more and more the displacement of the cylinder and from the tree until the door is completely closed.
  • a suitable damping fluid is a viscous gum.
  • a torsion spring is mounted between the shaft and the housing so as to be wound when the door is opened and to control the automatic closing by unwinding.
  • a preferred form of clutch is a coil spring clutch, which includes a coil spring which has one end anchored to the shaft, so that rotation of the shaft in the direction corresponding to the opening of the door tends to contract it and the shaft can rotate independently of the cylinder, while the rotation of the shaft in the opposite direction, during the closing movement of the door, tends to. unwind, causing it to attack the cylinder to rotate the latter with the shaft.
  • the door closer shown comprises a housing 10 provided with two end flanges 12 and 14 respectively which include bearings for a rotary shaft 16.
  • a cylindrical rotor 20 which in the embodiment of FIG . 1, journalled on bearing rings 22 housed in recesses on the internal face of the housing.
  • the cylinder 20 in fact comprises helical threads 24 and 25 with reverse pitch which are each in contact with one of these rings 22.
  • the threads 24 and 25 close the two ends ' of an annular chamber 26 formed between the cylinder and the housing and filled with a damping fluid constituted by a viscous gum.
  • An orifice 27 pierced in each flange 12, 14 and closed by a removable plug 28 allows the filling or emptying of the chamber 26.
  • a spring 30 In the cylinder 20, (Fig. 1) is mounted a spring 30, one end 31 of which is anchored to the shaft 16, by means of a drive plate 18, and the turns of which are normally applied by expansion against the internal face of the cylinder 20. However, when the shaft 16 rotates in the direction of the winding of the spring 30, the turns of the latter gradually move away from the cylinder 20 and eliminate the drive link between the two members which become independent in rotation.
  • the spring 30 thus constitutes a unidirectional clutch with a wound spring.
  • a torsion spring 32 anchored externally on the end flange 12 and internally on the rotary shaft 16, which tends to automatically return this shaft 16 to the closed position of the door.
  • the reference 34 designates a bearing element for the drive plate 18 and the reference 36 designates an elastic stop ring (circlip).
  • the door closer is mounted for use with its vertical axis; either end may be the upper end and any of the two elements, the shaft 16 and the housing 10, may be fixed.
  • the other element is connected to the door (or to the frame structure) via an articulated coupling.
  • the housing 10 is fixed to the door while the shaft 16 is connected by an articulated linkage 38.40 to the frame of the door.
  • the door closer is always mounted so as to obtain a free opening and a controlled automatic closing.
  • the door is opened, there is a relative rotation between the housing 10 and the shaft 16, which winds the torsion spring 32.
  • the clutch spring 30 is wound by the action of the drive plate 18 to take a smaller diameter, its contact with the cylinder is reduced so that the latter is not rotated. Opening the door has no effect in the damping chamber 26.
  • the torsion spring 32 unwinds by driving the shaft 16.
  • the spring clutch 30 then tends to relax and attack the cylinder 20, so that the latter is made integral in rotation with this shaft and rotates relative to the housing 10.
  • the damping fluid contained in the annular chamber 26 is then pushed back by the helical threads of reverse pitch 24, 25 towards the central part, without thread, of this chamber.
  • the reflux of the viscous fluid brakes the rotation of the cylinder 20 and consequently of the shaft 16 and thus slows down the closing movement of the door.
  • the action of the return spring 32 is thus effectively damped.
  • the fluid tends to spread throughout the chamber and fill the threads 24 and 25 at least in part.
  • the amount of gum used is preferably chosen so that this filling cannot be complete. This quantity can moreover be modified by introduction or extraction of gum by the orifices 27 provided with the screwed plug 28. An adjustment of the damping force can thus be obtained, with an amount of gum such that a greater proportion of turns or turns of the helical threads is filled with gum, a very significant damping effect is obtained.
  • clutch coil spring 30 can be replaced by another clutch system provided that it drives the cylinder 20 in the only direction of closing the door.
  • Figs. 3 to 6 show alternative embodiments of this clutch.
  • the mechanism shown in Figs. 3 and 4 comprises a housing 10, one of the flanges 12 of which is of single piece with the side wall / flange 14 serving as a cover for the assembly. Inside this housing, the threads 24 and 25 of the cylinder 20 are directly in contact with the internal surface of the housing, without the intermediary of any ring.
  • the clutch comprises two jaws 44, 46 (Fig. 4), externally circular but internally profiled, held axially between two retaining disks 48 and 50 respectively.
  • a cam 52 engaged with the internal profile of these two jaws is made integral in rotation with the shaft 16 by virtue of a diametrical key 54 formed on this shaft at the junction between the body thereof and the portion of smaller diameter 17 which passes through the bearing 55 of the flange 14.
  • the cam 52 is also engaged with two diametrically opposite radial fingers 56, 57 which are wedged at their end opposite the cam between the jaws 44 and 46.
  • La.came 52 is symmetrical with respect to its center and has on each side a recess 58 bordered by two shoulders or teeth 60, 61. One of the teeth pressing against the finger 56 or 57, while the other is engaged with the edge 62 of a recess 64 of the corresponding jaw, in the rest position or closing the p toe.
  • the clutch comprises an upper disc 70 which is integral with the rotating shaft thanks to two notches 71, and a lower disk which is free in rotation. 72, but susceptible of being made integral with the first thanks to a lug 74 of the latter which passes through a light 75 formed at its periphery.
  • the upper disc 70 carries two diametrically opposite rollers 76 which cooperate with pawls 78 articulated at 79 on the lower disc 72.
  • the pawls 78 are pushed outwards, and against the rollers 76, by a spring 80 preferably formed by a bent wire. In this position the pawls 78 protrude beyond the disc 70 or 72 and come into abutment against tabs 82 projecting inside the cylinder 20.
  • one end of the rotary shaft carries a drive tube which can rotate in bearings located in the cylinder, in the direction of the opening of the door, and the coiled spring clutch is housed at the center of the door closer, the torsion spring extending through the clutch spring, from an end flange located at one end of the housing to be housed in the drive tube, beyond the other end of the case.
  • the mechanism described in this specification is called a door closer mechanism, because this is its primary application, but it can also be used for applications such as closing doors. cupboards, box covers, tailgates for vehicles, rolling shutters, projection screen recall devices and, in general, for all similar applications in which a closing movement or a return movement must take place in an automatic and controlled manner.
  • the mechanism can be used to establish a coupling between two shafts in order to eliminate or reduce the transmission of vibrations.
  • the coiled spring allows the two shafts to be easily separated by imposing a reverse rotation on them.
  • a seal can be mounted around the cylinder at each of its ends but normally this is not necessary.
