Definitions

  • the present invention relates to a bidirectional closing mechanism for hinged members.
  • Closing mechanisms for hinged members are well-known in the art.
  • One such closing mechanism is illustrated in US Patent US 4,825,503 .
  • This closing mechanism comprises a rotational output, a shaft, an actuator connected to said shaft so as to urge said shaft in a first direction of rotation around a main axis of said shaft, and a rotation damper, also coupled to said shaft, with a substantially higher damping coefficient in said first direction of rotation than in an opposite second direction of rotation.
  • the closing mechanism can thus return to an initial closed position a hinged member linked to said shaft which is opened away from said initial direction against said actuator.
  • This prior art closing mechanism is reversible, so that it can be used for both clockwise and counter-clockwise opening hinged members by turning it around and using one or the other of the oppositely oriented first and second ends as an output.
  • the bidirectional closing mechanism of the invention also comprises at least a rotational output, a shaft, an actuator connected to said shaft for urging said shaft in a first direction of rotation around a main axis of the shaft, and a damper, coupled to said shaft, for damping rotation of said shaft with a substantially higher damping coefficient in said first direction of rotation than in an opposite second direction of rotation.
  • the closing mechanism of the invention achieves the abovementioned first object by also comprising a transmission between said shaft and said output, with a pinion coupled to said shaft, a first gearwheel directly engaged with said pinion, a second gearwheel coupled with said pinion over a reversing gear, and a toothed arc, coupled to said output, and extending between said first gearwheel and said second gearwheel, but not beyond both at the same time, so that, when it is moved in the direction of the first gearwheel, it turns said shaft, over said first gearwheel and pinion, in said second direction of rotation, whereas when it is moved in the direction of the second gearwheel, it turns said shaft, over said second gearwheel, reversing gear and pinion, in the same second direction of rotation.
  • the torque output of the closing mechanism over the toothed arc is reversed, without any adjustment or change to the closing mechanism.
  • said toothed arc may have a larger nominal radius than said pinion, preferably at least twice as large, even more preferably at least three times as large.
  • nominal radius of a toothed gear it is understood the distance between its centre and the contact point of its teeth with those of another gear which it is in engagement with.
  • said toothed arc presents an inner toothing. It can thus be arranged in a cap surrounding and preferably protecting the abovementioned gearing. This provides a particularly compact and reliable transmission.
  • said actuator may be a resilient element, preferably in the form of a torsion spring, in particular a coil torsion spring.
  • alternative actuators such as pneumatic, magnetic or electric actuators, could also be considered.
  • the closing mechanism according to the invention may thus comprise a mechanism for adjusting a preload of said actuating element.
  • said preload adjusting mechanism may comprise a worm in self-locking engagement with a worm-wheel connected to said actuating element. This provides and maintains an easily adjusted preload of the actuating element.
  • the damper may thus be hydraulic. More advantageously, the damper may comprise a cylinder barrel enclosing a cylinder cavity with a longitudinal axis, a damper shaft rotatable with respect to said cylinder barrel substantially around said longitudinal axis, and a piston placed within said cylinder barrel so as to divide the cylinder cavity into a first side and a second side in restricted fluid communication with each other; and a one-way valve allowing fluid flow from said first side to said second side of the cylinder cavity.
  • Said piston may then comprise at least one helical thread in engagement with a corresponding thread on either the cylinder barrel or the damper shaft, and a rotation-preventing member in engagement with a guide fixed to, or forming part of, the other one of said damper shaft or cylinder barrel, so that a rotational motion of the shaft with respect to the cylinder barrel results in a translational motion of the piston along said longitudinal axis.
  • this type of damper is particularly suited for use with a multiplying transmission, and thus with lower operating pressures while maintaining compact dimensions.
  • top should be understood as relating to the normal orientation of these devices in use. Of course, during their production, distribution, and sale, the devices may be held in a different orientation.
  • Fig. 1 illustrates a gate wing 1 mounted to a frame 2 with a hinge 3 and a closing mechanism 4.
  • This closing mechanism 4 comprises a rail 5 fixed to the gate wing 1, a main body 6 fixed to the frame 2, and an arm 7, with one end 7a fixed to an output 8 of the main body 6, and another end 7b slidingly engaged into the rail 5.
  • the purpose of such a closing mechanism is to close back the gate wing 1 after it has been opened.
  • the output 8 of the main body 6 exerts a torque urging the gate wing 1 back towards a closed position.
  • the closing mechanism 4 is damped.
  • the closing mechanism 4 presents a significantly higher damping coefficient in the closing direction than in the opening direction. In the prior art this in turn raised the problem of adapting the closing mechanism to right-hand and left-hand opening hinged members, as the damping direction conventionally needs to be changed.
  • the output 8 is mounted on a transmission 9, which is coupled to a rotatable shaft 10.
  • This rotatable shaft 10 is in turn connected to a damper shaft 11 of a rotation damper 12 and to an end 13a of a helical torsion spring 13.
  • An opposite end 13b of the helical torsion spring 13 is fixed to a worm-wheel 14 which is in self-locking arrangement with a worm gear 15 installed into the housing 16 of the closing mechanism 4.
  • the damper shaft 11 presents a helical outer thread 17 in engagement with a corresponding inner thread 18 of a piston 19 installed in a cylinder cavity 20 of a cylinder barrel 21.
  • the piston 19 also presents radial protrusions 22 for preventing rotation of said piston 19 with respect to the cylinder barrel 21.
  • a rotational movement of the damper shaft 11 is thus converted into a longitudinal movement of the piston 19 within the cylinder cavity 20.
  • a rotation of the damper shaft 11 which, seen from above, runs clockwise, displaces the piston 19 upwards, whereas a counter-clockwise rotation of the damper shaft 11 will displace the piston 19 downwards.
  • Alternative means are however at the reach of the skilled person.
  • the helical threads could be instead on the piston 19 and the cylinder barrel 21, and the rotation-preventing member placed between the piston 19 and the damper shaft 11.
  • Alternative rotation-preventing members such as, for example, simple pin-and-groove systems, could also be considered according to the particular needs of the user.
  • the cylinder barrel 21 is fixed to the abovementioned housing 16, and the rotation damper 12 also comprises a needle valve 24 which is accessible over a window 25 in said housing 16 for adjusting its damping coefficient.
  • Fig. 3 shows a front view of the main body 6 with the arm 7. Cut along line A-A of Fig. 3 , the transversal cut view of Fig. 3a illustrates in detail the transmission 9, as does the perspective cutaway of Fig. 3b .
  • This transmission 9 comprises a pinion 26 coupled in rotation to the shaft 10, a first gearwheel 27 directly engaged with said pinion 26, a second gearwheel 28 coupled with said pinion 26 over a reversing gear 29, and a inner toothed arc 30 extending between said first gearwheel 27 and said second gearwheel 28, but not beyond both at the same time.
  • the inner toothed arc 30 has a nominal radius four times that of the pinion 26, and is formed on the inside of a cap 31 which covers and protects the transmission 9, and on which the output 8 is formed.
  • the main body 6 and the arm 7 are also illustrated in their assembled state as a longitudinal cut view on Fig. 4 .
  • a lid 32 closes the top of the cylinder cavity 20 and holds the damper shaft 11.
  • Figs. 5 and 5a is in substantially unrestricted fluid communication with the rest of said first side 20a over at least one duct 34 in the damper shaft 11.
  • the first and second side 20a, 20b of the cylinder cavity 20 are in fluid communication with each other over the duct 35, which is restricted by the needle valve 24.
  • a one-way valve 36 at the bottom of the piston 19, is also interposed between said first and second side 20a, 20b of the cylinder cavity 20, and set to open when the fluid pressure in the first side 20a, here the upper side, is higher than that in the second, lower, side, so as to let hydraulic fluid flow from said first side 20a into said second side 20b.
  • a relief valve 37 is also incorporated into said one-way valve 36, so as to allow flow from the second side 20b into the first side 20a, but only if the overpressure in said second side 20b increases dangerously.
  • the illustrated hydraulic rotation damper 12 will not easily leak, and is therefore particularly suited for outdoors applications, such as gate closing mechanisms.
  • damper and actuator configurations can also be considered.
  • the shaft 10' is connected to the damper piston 19' over a rack-and-pinion transmission, so that the movement of the piston 19' within the cylinder cavity 20' is substantially perpendicular to the rotation axis of the shaft 10'.
  • the piston 19' divides said piston cavity 20' into a first side 20a' and a second side 20b' in fluid communication with each other over a duct 35' restricted by a needle valve 24'.
  • the damper 12' also comprises a one-way valve 36' allowing flow of fluid from the first side 20a' to the second side 20b' within the piston 19'.
  • the actuator is formed by a coil compression spring 13' within the cylinder cavity 20'.
  • it could also alternatively take the form of a torsion spring external to the damper 12', as in the first embodiment.
  • the shaft 10' is connected to the same transmission (not illustrated) than that of the first embodiment, so that, regardless of whether the output (not illustrated) connected to the shaft 10' through said transmission is rotated clockwise or counter-clockwise from a neutral position, the shaft rotates clockwise, displacing the piston 19' against the compression spring 13', as illustrated in Fig. 7a .
  • the one-way valve 36' allows the hydraulic fluid to flow from the first side 20a' to the second side 20b', opposing scant resistance to the movement of the piston 19'. Once the output is released, the spring 13' will push the piston 19' back, as illustrated in Fig. 7b . However, since the one-way valve 36' will not allow flow from the second side 20b' to the first side 20a', all the returning hydraulic fluid will have to flow through the restricted duct 35', damping the return movement of the piston 19' and the output.
  • the closing mechanism could also be formed as a hinge, with the rotational output 8 acting directly onto the hinged wing or frame, instead of over the arm 7.
  • the housing of the closing mechanism could be fixed to a fixed frame, and the output connected to the hinged member, as illustrated in Fig.
  • the housing of the closing mechanism could be fixed to the hinged member and the output connected to the fixed frame, as in US 6,891,479 B1 . Accordingly, the description and drawings are to be regarded in an illustrative sense rather than a restrictive sense.
