Definitions
- This invention relates to a stop for a door or window assembly, for holding the door or window in a predetermined open position.
- the invention is especially suitable for a door assembly including an automatic door closer, but the invention is not limited exclusively to this.
- door stops and window stays are known.
- the most common form of door stop is a wedge insertable between the floor and the lower edge of the door. Such a wedge is typically unsightly in use, and is also unsightly when left on the floor when the door is closed.
- Another common door stop is a hook mounted on the door or on an adjacent wall by which the door can be hooked to the wall to hold the door open. The presence of a hook and a keep (e.g. an eye) on the face of the door and on the wall is also very unsightly.
- one aspect of the present invention provides a door or window assembly comprising a frame member, a leaf hingedly moveable relative to the frame member, and stop means for acting between the frame member and the leaf for holding the leaf in a predetermined open position, said stop means being substantially concealed from view when the leaf is in its closed position.
- the leaf may be the openable door or window of the assembly.
- the stop means acts between the frame member and a rear edge of the leaf adjacent to the frame member.
- the stop means comprises a member mounted on the rear edge of the leaf.
- the stop means comprises a hook and a keep mounted one on each of the frame and the leaf.
- the hook is capable of hooking engagement with the keep to maintain the leaf in its open position.
- the keep comprises a spigot.
- the spigot is received in an aperture or recess of the member on which the hook is mounted.
- the spigot may be retractable.
- the assembly further comprises hinge means coupling the leaf to the frame member.
- the stop means comprises a member mounted on the same portion (or edge or face) of the frame member as the hinge means.
- he present invention also concerns a release control system for remotely operating at least one stop means.
- the release control system is operable to release at least one stop means in response to receiving a signal from a fire alarm system.
- the release control system is operable to release at least one stop means in the event that a power supply unit fails.
- the release control system is operable to cause the release of individual or groups of stop means in response to user and/or automatic input signals.
- such an optional embodiment release control system comprises a programmable release unit.
- Fig. 1 is partial side view showing a door in an open position
- Fig. 2 is a schematic section along the line II -II of Fig. 1
- Fig. 3 is a front view of the hook unit shown in Fig. 1
- Fig. 4 is a schematic side view of the hook unit
- Fig. 5 is a side view of the keep member shown in Fig. 1 ;
- Fig. 6 is a partial side view similar to Fig. 1 showing a modified embodiment:
- Fig. 7 shows a side view of a keep unit having a retractable spigot;
- Fig. 8 shows a side view of an electrically operable keep unit having a retractable spigot;
- Fig. 9 shows a release control system incorporating a plurality of electrically operable keep units of the type shown in Fig. 8.
- a door assembly 10 comprises a leaf in the form of a door 12, which may be solid, partly glazed, or fully glazed.
- the door 12 is hingedly mounted to a frame member 14 by one or more butt hinges 16. It will be appreciated that one, two or more hinges 16 may be used as desired, but for the sake of clarity only one hinge 16 is illustrated in Fig. 1.
- the door assembly 10 includes a door stop 18 in the form of a hook unit 20 and a keep unit 22 with which the hook is capable of hooking engagement.
- the hook unit 20 is mounted on the door 12
- the keep unit 22 is mounted on the frame member 14.
- the positions of the hook unit 20 and the keep unit 22 may be interchanged.
- the hook unit 20 is mounted within a recess or cut-out on the rear edge 23 of the door.
- the hook unit 20 comprises a mounting surround 24 including a generally circular aperture or recess 26, and a channel-like recess 28 for receiving a hook member 30.
- the hook member 30 is pivotally secured at its upper, proximal end to the surround 24 by a pivot pin 32. As best seen in Fig. 3, the hook member 30 is somewhat narrower than the channel 28, to permit lateral movement of the hook member 30 within the channel. At its lower, distal end, the hook member 30 has a recess 34 for hooking engagement with the keep.
- the keep unit 22 comprises a base 36 from which projects a spigot 38 dimensioned to be receivable in the aperture or recess 26 of the hook unit 20. Towards its distal end, the spigot 38 has a slot 40 which can co-operate with the recess 34 of the hook member 30 to enable the hook member to hookingly engage the spigot 38.
- the hook member 30 When the door is moved to its open position (Figs. 1 and 2), the hook member 30 can be lifted (e.g. using one's finger), and hooked onto the spigot 38 (by cooperating with the slot 40). In that condition, the hook and the keep act as a door stop to prevent the door from closing. This is especially useful if the door is likely to swing shut under gravity, or be blown shut. It is also especially useful if the door assembly includes a door closer (not shown) for automatically drawing the door closed. To close the door, it is necessary simply to unhook the hook member 30 from the spigot 38, and allow the hook member 30 to drop back into the channel 28 of the hook unit 20. The door is then free to be closed.
- the spigot 38 enters the aperture or recess 26 of the hook unit 20.
- a recess shown in phantom at 42
- the spigot 38 In the fully closed position of the door 12, the spigot 38 is received within the aperture or recess 26 (and the recess 42 if provided) to provide a dead-bolt security feature. In other words, even if the butt hinges 16 are destroyed or damaged by a burglar attempting to gain entry through the door, the spigot 38 engaging in the recess or aperture 26 functions to prevent the door 10 from being slid forward out of its frame.
- the optimum dimensions of the hook member 30 and the spigot 38 will depend upon the specific arrangement of the door assembly, and the desired angle to which the door can be opened. It may be convenient to manufacture one or more of the hook unit
- unit 22 in different sizes, and allow a user to choose a desired size (or combination of sizes) to suit a particular installation.
- the hook member 30 is laterally moveable relative to the surround 24. This is provided to allow movement of the hook member 30 to accommodate a particular installation. It will be appreciated that, if desired, the hook member 30 might not be laterally movable.
- Fig. 6 illustrates a second embodiment in which a longer hook member 30a is used, and the surround 24 has a longer channel 28 to accommodate the longer hook member 30a.
- the second embodiment functions in the same manner as the first embodiment.
- Fig. 7 shows a side view of a keep unit 52 having a retractable spigot 56.
- the keep unit 52 may be used as an alternative to the keep unit 22 shown in the embodiments of Figures 1, 2, 5 and 6.
- the keep unit 52 comprises a retractable spigot 56, preferably smooth surfaced, mounted within a keep unit housing 54.
- the retractable spigot 56 can be moved in a lateral direction.
- the keep unit 52 further comprises a resilient biasing means 58 that biases the retractable spigot 56 in a biased position against the inner surface of the keep unit housing 54.
- a protruding push pin 57 extends through the outer surface of the keep unit housing 54 adjacent the retractable spigot 56.
- the retractable spigot 56 engages the hook member 30 to hold the door 12 in an open position.
- a user of the system pushes the push pin 57 and the retractable spigot 56 slides laterally so as to disengage from the hook member 30.
- the resilient biasing means 58 then operates to return the retractable spigot 56 back to the biased position ready for the hook member 30 to be re-engaged should the door 12 require to be held open again.
- Fig. 8 shows a side view of an electrically operable keep unit 60 that may be used as a replacement for any of the other keep units previously described.
- the electrically operable keep unit 60 comprises a retractable spigot 68 slidably mounted in a keep unit housing 62.
- the retractable spigot 68 is connected to the keep unit housing 62 by a resilient biasing means 70 that is held under tension.
- the resilient biasing means 70 tends to draw the retractable spigot 68 into the keep unit housing 62 when no other forces are applied to the retractable spigot 68.
- the lateral movement of the retractable spigot 68 in the bore of the keep unit housing 62 is restricted in at least an outward direction by a rim or lugs formed on the retractable spigot 68 itself and the inner wall of the bore of the keep unit housing 62.
- the keep unit housing 62 comprises a keep unit housing projection 63 that acts as a dead-bolt security feature which engages with the door 12 when the door 12 is in a closed position. Additionally the keep unit housing projection 63 houses a solenoid winding 64 that surrounds at least a portion of the retractable spigot 68.
- the retractable spigot 68 is preferably made of a magnetically active material such as, by way of non-limiting example only, iron or a permanently magnetised material.
- the solenoid winding 64 may be connected via solenoid power leads 66 to an external current source so as to produce a magnetic field within the core of the solenoid winding 64.
- the magnetic field within the core of the solenoid winding 64 acts upon the magnetically active retractable spigot 68 and forces the retractable spigot 68, against the action of the resilient biasing means 70, towards the outwardly extended position. In the maximum outwardly extended position the retractable spigot 68 may engage the hook member 30 to hold the door 12 open.
- the retractable spigot 68 is preferably smoothed surfaced.
- the resilient biasing means 70 pulls the retractable spigot 68 inwards and disengages the retractable spigot 68 from the hook member 30 if it is attached, and thereby releases the door stop allowing the door 12 to close.
- doors 12 may be closed.
- the doors also close since insufficient current is supplied to the solenoid winding 64 to hold the retractable spigot 68 in an engaged position. This feature is advantageous since if a power failure occurs, for example during a building fire where doors and windows need to be closed to prevent the spread of fire, any doors and windows incorporating this embodiment of the present invention will close automatically.
- the solenoid may be active to retract the spigot against a resilient biassing means acting against the spigot to force it out of the keep.
- other "fail-safe" electrically operable and/or pneumatically operable keep units may be used that act to release the door stop mechanism 18 should there be a failure of power.
- Fig. 9 shows a release control system 72 incorporating a plurality N of the electrically operable keep units 60 as shown in Fig. 8. Although a plurality N of the electrically operable keep units 60 are shown, it is to be understood that N can range from unity to any integer number.
- the release control system 72 comprises a control unit 80 that is operable to control the supply of current to the plurality of electrically operable keep units 60.
- the release control system 72 is responsive to one or more signals received from a fire alarm system 84 to cut the power supplied to all of the electrically operable keep units 60 so that the doors or windows associated with respective of the electrically operable keep units 60 is cut.
- the fire alarm system 84 forms part of the release control system 72, but it is to be understood that in any building where a release control system 72 according to an embodiment of the present invention is to be installed, the fire alarm system 84 may already be installed and merely need to be connected to the control unit 80.
- Control unit 80 is connected to a power supply unit 82 which is preferably also used to power the fire alarm system 84.
- the power supply unit 82 provides power for the control unit 80 and the quiescent current needed to power the electrically operable keep units 60. Should the power supply unit 82 fail, each of the N electrically operable keep units 60 releases its associated door stop mechanism 18, enabling all doors and windows to close.
- Fig. 9 Also shown in Fig. 9 is an optional programmable release unit 86.
- This unit can be used to program the release of either individual or groups from among the N electrically operable keep units 60. This permits programmable closing of doors and/or windows in groups or individually, and may be of assistance for security guards, automated climate control systems etc.
- the action to remove power from any of the N electrically operable keep units 60 may be either manually initiated by pushing a button/key etc. or automated by use of timing or other triggering signal.
- the hook unit 20 and the keep unit 22 are of metal for optimum security.
- Keep unit 52 is also preferably formed using metal components.
- Keep unit housing 62 is also made of metal for optimum security.
- any suitable material may be used, such as tough plastics.
- the door assembly 10 may be for a wooden door, or a metal door, or a plastics (e.g. u-PVC) door.
- a door stop which is simple to use. and is aesthetically discrete. In particular, when the door is closed, the door stop mechanism is substantially hidden from view.
- the preferred embodiments also provide a dead-bolt security feature to improve the security of the door (or window) assembly.
- any form of suitable engagement means between the rear edge of the door and the frame may be used, whether it be pivoted, or slidable, or a combination of both.
