Definitions

  • the present invention relates to a door operating mechanism and in particular to a mechanism for controlling the opening or, more especially, the return of a door.
  • actuating means coupled to a part of the door, which actuating means is energised or charged up on opening of the door and then is released after opening to close the door. It is preferable to control the rate of closing.
  • the known door closing mechanisms use a spring which is compressed on opening of the door by an actuating lever actuated by movement of the door and which acts directly on the spring, whilst the rate of closing is controlled by means of hydraulic fluid acting as a damper. the fluid being forced into a chamber on opening and acting on the actuating means in a direction to oppose closing so that by controlling the return flow of fluid the rate of closing is controlled.
  • a door operating mechanism comprising a casing accommodating a piston member which is axially movable in a piston chamber against fluid means, a pivot member which is rotatably mounted relative to the casing, and means interconnecting the piston member and the pivot member whereby rotation of the pivot member causes axial movement of the piston member and vice versa, the fluid means serving as return means.
  • the means interconnecting the piston and pivot members may be a part of the piston member, say as an extension, or separate from, but say connected thereto.
  • the fluid means acting on the piston member to urge it axially and thereby generate rotation of the pivot member relative to the casing.
  • the casing is received in a bore in the door on the pivot axis thereof and the pivot member is located non-rotatably relative thereto, say in a recess in the floor.
  • the casing may be part of the door. Opening of the door causes the piston member to be displaced axially by the relative rotation of the casing relative to the pivot member.
  • This axial movement is preferably used to displace hydraulic fluid from the said piston chamber to a second piston chamber to move a second piston therein which is acted on by a spring.
  • valve means is interposed between the (first) piston chamber and the second piston chamber. It is also advantageous for the area of the second piston chamber to be smaller than that of the first. More preferably, the valve means comprises a check valve allowing relative free flow of fluid from the first chamber to the second chamber whilst inhibiting, indeed preventing, flow in the reverse direction.
  • the valve means also comprises a restricting jet, which serves to allow flow between the first and second chambers, but with restriction, preferably adjustable restriction, and which serves to control the release of pressure from the second chamber to drive the piston member axially and thus return the door to its closed position.
  • the pivot member comprises a multi-start helical formation, with helical grooves and ridges extending axially, and which cooperate with complimentary helical fingers of an axially movable member, with the fingers received in the complimentary helical grooves.
  • the movable member serves to actuate the piston member.
  • the movable member is keyed to the casing conveniently by way of pins received in axial slots in the casing, so as to be axially movable but non-rotatable relative thereto.
  • the piston member is connected to the axially movable member. Conveniently, the connection is such as to allow rotation of the piston, primarily to increase seal life, and to allow restricted axial movement therebetween. This gives a slight delay before the closing force starts to effect closure of the door as axial movement of the piston is not immediately transmitted to the axially movable member cooperating with the pivot member.
  • the described co-operating helical formation and helical fingers are particularly advantageous, because, they enable large surface areas to be achieved, giving minimum wear.
  • the helical members may be of cast metal, but advantageously by making the helical members out of plastics, such as nylon, lubrication can be built in to ensure free action.
  • actuating means may be employed using a nut and threaded member, say a multi-start, fast thread.
  • a helical cam track can be provided and a cooperating abutment, say a two start internal cam track with a T-shaped abutment, having respective rollers for cooperating with a respective one of the cam tracks, axial movement being transmitted to the abutment to move the piston, on rotation of the helical cam track.
  • a cooperating abutment say a two start internal cam track with a T-shaped abutment, having respective rollers for cooperating with a respective one of the cam tracks, axial movement being transmitted to the abutment to move the piston, on rotation of the helical cam track.
  • the construction could equally be reserved.
  • the described construction may be modified in a simple manner to provide additional and/or alternative features which are particularly useful.
  • a hold facility can be easily incorporated by providing means to hold the first piston, but preferably the second piston, in a selected displaced position.
  • the door/piston member can be held anywhere between its starting position and displaced position. This could be equated to closed and open positions of the door. Especially useful is to be able to hold the door open for flow of traffic but allowing closure, say automatically on releasing of the hold device.
  • the holding may be done magnetically, by having a solenoid hold the second piston in a predetermined displaced position.
  • a latch mechanism could be employed to hold the piston in position, with the latch released electro-mechanically.
  • the opening of the door could be controlled indeed prevented from opening, simply by arranging for the position of the check valve to be selectively controlled. If the check valve is held closed, then fluid is prevented from being displaced from the first chamber to the second chamber, thus creating in effect a hydraulic lock within the system. This could be done preferably electro-mechanically by a suitably magnetic solenoid, or otherwise mechanically. Of course, preventing the second piston member from displacement against the spring force could also create such a hydraulic lock giving the same effect.
  • a further alternative is to have automatic opening and/or closing of the door by connecting a pressurised hydraulic circuit into the piston chamber.
  • the second piston and spring could then be dispensed with and optionally the valve means if this incorporated in the auxiliary hydraulics.
  • Closing of the door can be achieved by introducing pressurised fluid into the piston chamber and then opening the chamber to a return line to allow fluid out on opening of the door.
  • Opening and closing could be controlled by providing a double acting piston member.
  • the door return mechanism comprises a casing 1, which is conveniently a tubular aluminium sleeve, say with a tube wall thickness of 3mm, a piston member 4 received slidably in part of the casing acting as a first piston chamber 27, a pivot member 7 received rotatably in the casing and means interconnecting the pivot member 7 and the piston member 4.
  • the pivot member 7 comprises a solid member having a plurality of helical ribs 29 (four in the illustration) extending axially from a base portion 31 and with interposed helical grooves.
  • the helical formation may be in the form of helical fingers.
  • Secured to the base portion across a diameter thereof by countersunk screws 25 is an elongate rib 10, conveniently tapered in a cross-section.
  • the pivot member 7 co-operates engagingly with the inter-connecting means in the form of a member 6 as shown in Figures 3 to 5 which comprises four helical fingers 33 which are shaped to interengage with the helical fingers 29 of the pivot member 7.
  • the member has one or more transverse bores 3 receiving pin means 5 projecting from the outer periphery of the member, and in use, said projecting ends being received in a respective axial grooves 37 in the casing 1. This serves to constrain the member in the casing allowing axial movement, but no rotation.
  • connection with the piston member 4 is such as to allow rotation of the piston and to compensate for any axial misalignment of the member 6 so that the piston runs true in the bore of the casing. This gives good seal life.
  • the piston member 4 is conveniently cylindrical with a plurality of grooves accommodating seals 18. The lose connection also gives rise to a delay action.
  • the piston member 4, member 6 and pivot member 7 are each preferably made of plastics, conveniently by moulding.
  • a nylon or polypropylene with self lubricating properties are conveniently employed.
  • the large surface area reduces wear and spreads the loading.
  • the piston member 4 is movable in the aforementioned piston chamber 27 which accommodates hydraulic fluid and which chamber is in communication with a second chamber 41 having disposed slidably therein a second piston 3. Movement of fluid from the first chamber 27 to the second chamber 41 causes the second piston to be displaced against the force of a spring 16 which takes its abutment between a rear face of the piston 3 and an end wall 8 of the casing 1.
  • the second chamber 41 is conveniently formed within a sleeve member 2 which is received in the casing and located thereto by screws 26 passing through the casing. Conveniently the sleeve is made of aluminium. The diameter of the second chamber and hence that of the second piston, is less then that of the first piston.
  • the second piston 3 is sealed in the bore of the second chamber by seals 17.
  • valve means Interposed between the first and second chambers is valve means comprising a plate 9 threaded into the end of the sleeve 2 and incorporating a check valve 20 and a restricting valve 21.
  • the valves are associated with separate through bores 43, 45 in the valve plate.
  • the check valve 20 allows hydraulic fluid to pass from the first chamber to the second chamber relatively unhindered whilst flow in the reverse direction is prevented (i.e. checked).
  • the check valve can take the form of a simple ball valve engaging against a tapered seat, with or without spring biasing.
  • the restricting valve 21 controls the flow of fluid from the second chamber to the first.
  • the restricting valve 21 comprises a threaded screw received in a threaded bore of the valve plate with provisions for leakage of fluid past the threads.
  • a given screw will have a predetermined resistance and adjustment of the restriction can be achieved by changing the screw or the length threaded into the bore.
  • An O ring seal 19 seals the sleeve 2 relative to the casing to prevent fluid entering between the two.
  • a bleed screw 22 is conveniently provided for bleeding the fluid chamber. This is conveniently disposed in the sleeve 2 and opens into the second chamber, and accessible through an aperture 49 in the wall of the casing 1.
  • the device operates as follows:-
  • the device In use the device is fitted into a bore in the door and is intended to be fitted on the pivot axis of the door.
  • the bore is preferably close fitting so as to serve as reinforcement to the casing, and preferably the part of the door into which it fits comprises an aluminium extrusion.
  • the device is vertical in use with the elongate rib 10 projecting from the bottom edge of the door and received in a location point on the floor or still beneath the door.
  • the casing is secured non-rotatably relative to the door.
  • the check valve 20 offers little or no resistance to opening or at least a predetermined resistance.
  • the spring can act to return the fluid from the second chamber 41 to the first chamber 27 and so displace the piston member 4 axially and cause the casing and hence the door to rotate and thereby return to its closed position.
  • the restricting valve limits the flow rate of fluid so that the door closes at the desired rate whilst the check valve closes under reverse flow conditions.
  • the check valve can be actuable either adjustable variable to control the permitted rate of opening of the door, or at least to have selective open and closed positions, whereby in the closed position the door is prevented from being opened by the presence of an hydraulic lock within the first chamber. This would be done electro-magnetically or mechanically, with a switch positioned on the door adjacent the mechanism or disposed remotely.
  • a further possibility is to have a hold facility whereby the door can be held in an open position or any selected intermediate position. This can be done by electro-magnetic means, incorporating a solenoid to hold up the second piston until a release signal is received.
  • the restricting valve could further incorporate serially a check valve, electro-magnetically operated, to close the return path selectively.
  • a still further option is to provide remote power operation of the door, possibly for both opening and closing by having the piston 4 subject selectively to hydraulic fluid pressure from a source.
  • the pressure could be applied to close an open door and/or to hold closed a door by pressurising the piston chamber.
  • Opening could be catered for by modification of the piston to be double acting with appropriate porting.
  • the helical actuated mechanism illustrated is of right hand thread configuration and is for use with a door opening in an anticlockwise direction with a clockwise return direction. Where the door is to open in the clockwise direction, a left hand thread configuration is required for the pivot member 7 and the interconnecting member 6. Alternatively, the same right handed configuration could be employed if it is positioned at the top edge of the door rather than the bottom, i.e. if the mechanism is inverted.
  • Figure 7 shows the pivot member 7 ⁇ and interconnecting member 6 ⁇ in their interengaged return position for the case of a double acting (swing) door.
  • the length of both the members 6 ⁇ and 7 ⁇ is increased by approximately 25 mm (or an amount equal to the axial displacement of the interconnecting member for the desired opening angle (say 90 degrees).
  • the pivot member 7 ⁇ is solid with helical ribs 29 defining helical grooves receiving helical fingers 33 ⁇ of the interconnecting member 6 ⁇ .
  • the two members are interengaged by the same amount as previously, but the end 60 of the interconnecting member 6 ⁇ is spaced from the base part 72 of the pivot member 7 ⁇ by the above mentioned increased amount and the end 70 of the pivot member is likewise spaced by said increased amount from the top end of the interconnecting member 6 ⁇ .
  • piston member 4 it may be preferably for the piston member 4 to be the same diameter as the second piston member 17 (when provided) to equalise the return closing force.
  • Figure 8 shows an alternative construction of actuating means, in which the pivot member 7 ⁇ comprises a member 80 extending upwardly from a base part 82 rotatably mounted in the casing 1 ⁇ of the mechanism at 83.
  • An elongate rib 10 ⁇ is provided for locating the pivot member 7 ⁇ relative to the floor, frame or fixed part relative to the movement door.
  • An interconnecting means 6 ⁇ is provided constructed essentially as before, namely a two start helical thread as illustrated made up of fingers 33 ⁇ .
  • rollers 84 Cooperating with the helcial track of the fingers are rollers 84 mounted on the ends of transverse arms 86 branching from the member 80.
  • the rollers 84 are journalled for rotation on the arms, and roll on the helical cam track surfaces defined by the fingers.
  • a minimum of two rollers are provided, with four being a preferred number, the other two being disposed at right angles to those illustrated in section.
  • the cooperating engagement between the rollers and the cam track gives rise to axial displacement of the interconnecting member 6 ⁇ on rotation of the door.
  • the mechanism otherwise operates as described previously for controlled return of the door.
