  • the casing (2) also comprises two tubular rollers (5, 6) each movable in rotation along an axis oriented parallel to said first direction A.
  • Said rollers (5, 6) each cooperate on the one hand with said shaft (4) and on the other hand respectively with a piston (7, 8) movable in translation along an axis oriented according to the second direction A '.
  • a first piston (7) is subjected to the action of return means and a second piston (8) separates two hydraulic chambers (9, 9 ') connected by a system ducts (18).
  • the housing has a length off all about 35 cm; the housing (2) has a width of about 3.5 cm and a height about 4.2 cm and the cylindrical tube (3) has an outside diameter of about 3.5 cm.
  • said return means comprise a plurality of washers Belleville (10) identical or different mounted substantially coaxially according to said second direction A '.
  • said Belleville washers (10) are mounted on a central guide tube (11) whose the axis coincides with the axis of the cylindrical tube (3).
  • 100 identical washers made of steel were each with an outer diameter of 32 mm and an inner diameter of 16 mm height of 2 mm, all in simple opposition, that is to say with the concavities of adjacent washers in opposition.
  • This arrangement has made it possible to obtain a piston stroke (7) of the order of 10 cm.
  • the durability of the return means is increased because the tests conducted have have shown that return means consisting of Belleville washers can reach the million cycles without significant loss of characteristics, whereas a coil spring of equivalent dimension does not exceed 500 thousand cycles without significant loss of characteristics.
  • a Belleville washer also called “spring washer” is, in a way known an annular washer, usually made of metal or metal alloy, having an inner diameter and an outer diameter, the inner diameter being less than the outside diameter, the annular shape being not flat but conical.
  • a Belleville washer extends over a height greater than the thickness of the material constituting the ring.
  • a Belleville washer depends on the compressive force at which she is submissive. This compression is usually oriented parallel to the axis of the annular form. Generally, a Belleville washer is made of a material elastic and it resumes its initial height when it is no longer subject to a force of compression.
  • the washers that were selected all had the same inside diameter and the same outside diameter, the same thickness and the same height at rest.
  • washers that all have the same diameter interior but some of which have a different outside diameter, as well as possibly a different thickness and / or height.
  • rollers (5, 6) are respectively mounted each on a cylindrical pin (13, 14), via, for the roller (5) of needles (12) mounted between it and the cylindrical pin (13).
  • the outer diameter of the rollers (5, 6) is constant over their entire length, but the shaft (4) has a cam constituted by an increase in its radius of curvature outside substantially the full height of the cam profile in contact with the rollers (5, 6).
  • the shaft (4) is preferably mounted at an upper end on a tubular needle socket (24) and at one end lower on a bearing (20), for example a ball bearing.
  • the distal end of the housing that is to say the end furthest from the shaft (4) is provided with a thread on the inner face of the cylindrical tube (3).
  • This threading is intended to allow screwing a distal plug (21) having on its outer surface a complementary thread.
  • a hardened steel washer (22) is positioned at each end of the return means to prevent premature wear of the contact surface on the one hand the distal plug (21) and on the other hand the piston (7).
  • the piston (7) is provided at its periphery with an O-ring (23) in contact with the face inside the housing (2) to prevent the oil in the chamber (9) from spread in the cylindrical tube (3).
  • the piston (7) is thus in contact, at a first end with respect to the direction A 'with a washer (22) and at the other end with the roller (5).
  • An O-ring (19) is also positioned around the shaft (4), at the upper cap (25) which holds the inner part of the shaft (4) in the housing (2).
  • the proximal end of the housing that is to say the end closest to the shaft (4) is also provided with a thread on the inner face of the housing (2). This thread is intended to allow screwing a proximal plug (26) having on its outer surface a complementary thread.
  • the piston (8) is also provided at its periphery with an O-ring (27) positioned in the inner face of the housing (2), to prevent the oil in the chamber (9, 9 ') is propagated respectively in the other chamber (9', 9) without going through the ducts (18) formed in the wall of the casing (2).
  • the piston (8) is thus in contact with a first end relative to the direction A 'with the roller (6) and at the other end with the bedroom (9 ').
  • a spring (16) is positioned in this chamber (9 '), substantially coaxial with the direction A ', between the face of the piston (8) and the face of the proximal plug (26) adjacent.
  • a safety valve (17) is also positioned between the two faces opposing the piston (8) relative to the direction A ', to allow the passage of the oil from the chamber (9 ') to the chamber (9) in case of overpressure.
  • a non-return valve (15) is also positioned between the two opposite faces of the piston (8) with respect to the direction D, visible in FIG.
  • the two ducts (18), visible in FIGS. 4 and 5, are each provided with a needle (28) to regulate the oil flow and therefore the speed of return of the door in its closed position (0 °) and each have at their end opening on the face outer casing (2) a locking ball (29).
  • a filler cap (30) is used to fill the door closer with oil through the housing wall (2).
  • the second variant differs from the first essentially by the positioning of the non-return valve (15), the number of springs (16) and the absence of a filling plug (30), as can be seen by comparing the figures.
  • the door closer (1) allows the opening of the door in both directions of opening, 0 ° to 180 ° and causes its automatic closing. However, it is obvious that he can also be used for a door opening only in one direction and at an angle less large, 90 ° for example.
  • This door closer causes the soft closing of the door from the maximum angle opening to the fully closed position.
  • the door closer force is adjustable from 3 to 5 (according to EN1154) by via a set screw on which it is possible to act, for example with a six-sided key.
  • the closing speed is adjustable over two ranges: from 0 to 25 ° for the end of race; from 0 ° to 180 ° over the entire closing range.
  • Step one Opening the door
  • the door is taken directly on the axis of the door closer.
  • the opening of the door drives the shaft (4) in rotation. This rotation causes the translation of two pistons (7, 8), via the two rollers (5, 6).
  • the piston (7) moving comes to compress the damper means consisting of washers (10) of the "Belleville" type assembled heads spades.
  • the stack of washers is previously prestressed when mounting the device.
  • the triggering pressure of the valve is obtained from design: no calibration necessary, the stiffness of the spring of the valve, its length in charge and the surface of Oil passage define this pressure.
  • the choice of means is simplified. closing according to the desired torque. Indeed, knowing the resistance values at the compression of each washer, it is possible to realize the return means in selecting a plurality of identical or different Belleville washers (10) and substantially coaxially mounting said Belleville washers (10) according to said second direction A ', said selection and said assembly being operated according to the desired force which is exerted by said biasing means on said first piston (7), integrating, by example the weight of the door or an average weight.
  • cam profile for the tree of training (4), to coordinate the weak race with the important effort transmitted.
  • the definition of this form is within the reach of the skilled person.
