Description
AN ACTUATOR HANDLE ASSEMBLY
This invention relates to an actuator handle assembly for controlling the opening and closing of a closure member relative to a fixed frame, such as an openable door or window mounted in a fixed rectangular frame.
The actuator handle assembly of the invention may function as a latch e.g. a casement or cockspur type handle and / or may function as a door or window lock by being coupled, for example, to actuate an espagnolette type lock fitting, of the type known for use particularly with UPVC units.
Known actuator handle assemblies generally comprise a mounting plate, a handle pivotally mounted on the mounting plate for movement between a retaining position corresponding to a closed position of the closure member (door or window) and a release position permitting movement of the closure member to an open position, and in which the handle comprises a body portion by which the handle is pivotally connected to the mounting plate and a hand grip portion connected to the body portion. In the case of known locking handles, an actuator shaft is coupled with the handle and which can be drivingly coupled with an input fitting to an espagnolette type of sliding bolt fitting. In the case of a known casement handle, a laterally projecting nib or tab may be provided on the body portion of the handle, which can latch with a fixed keeper plate.
It is also known to provide a linearly movable plunger and a recess to hold the projecting end of the plunger captive, one of which is provided in the mounting plate and the other of which is provided in the body of the handle portion, and which interengage when the handle is in the closed position in order to retain the handle in the closed position after movement thereto. It is further known to provide a push button release arrangement within the body portion, which can be depressed in order to disengage the plunger from the recess prior to movement of the handle to the open position.
The present invention is concerned with an actuator handle assembly having an improved means to retain the plunger in a withdrawn position, after operation of the push button release arrangement, while the handle is occupying all positions other than the fully closed position.
According to the invention there is provided an actuator handle assembly for controlling the opening and closing of a closure member relative to a fixed frame, said assembly comprising:
a mounting plate;
a handle pivotally mounted on the mounting plate for movement between a retaining position corresponding to a closed position of the closure member and a release position permitting movement of the closure member to an open position, said handle comprising a body portion by which the handle is pivotally connected to the mounting plate and a hand grip portion connected to the body portion;
a plunger slidably mounted in the body portion for movement between a withdrawn position and a projecting position with respect to the body portion;
biasing means arranged to urge the plunger towards the projecting position;;
a recess arranged in the mounting plate to receive and to hold captive the projecting end of the plunger when the latter is in the projecting position and when the handle is in its retaining position;
a push button mounted in the body portion and operative to effect movement of the plunger from the projecting position to the withdrawn position against the action of the biasing means; and,
a retainer element mounted in the handle body portion and movable between a retaining position and a release position with respect to the plunger, in which: (1) the retainer element is engageable with the plunger, when the retaining element is in its retaining position and the plunger is moved to its withdrawn position, in order to retain the plunger in its withdrawn position during movement of the handle to and from its release position; and, (2) the retainer element is engageable by an actuator element to move to its release position as the handle moves to its retaining position, in order to release the plunger and thereby allow the latter to move to its projecting position of captivity with the recess in the mounting plate under the action of the biasing means when the handle reaches its retaining position.
Thus, an actuator handle assembly according to the invention houses the major part of the operating components within the handle body portion (the push button, the plunger and the retaining element), which is well able to accommodate these components, and this allows the mounting plate to be of thin plate construction as it is only required to mount the actuator assembly on a suitable part of the closure member (or the fixed frame) via suitable fixings, and to accommodate the recess in which the projecting end of the plunger is held captive when the handle is in its retaining position.
In a preferred arrangement, the actuator handle assembly is mounted on a movable frame or sash of a window which is mounted in a fixed window frame, and when the handle is pivoted to the retaining position after movement of the window to the closed position, the actuator assembly can operate any required latching and / or locking mechanism to hold the window in the closed position.
By way of example only, the actuator handle assembly may be coupled e.g. via a drive shaft to a sliding bolt (espagnolette) type fitting which moves to lock with a corresponding fixed keeper arrangement in the fixed frame.
Alternatively, the actuator assembly may house a latch element e.g. a laterally projecting nib or tag engageable with a fixed element on the fixed frame so that the actuator assembly may function as a latching handle e.g. a cockspur or casement type handle.
Preferably, the biasing means for the plunger comprises a spring housed within the handle body portion and arranged to bias the plunger in a direction towards the projecting position. Similarly, a further spring may be housed within the body portion to bias the retaining element in a direction towards its retaining position in which it is capable of engaging and retaining the plunger when the latter is moving towards, or is at its withdrawn position.
Any suitable operative connection may be provided within the body portion to enable the push button to effect release movement of the plunger to the withdrawn position e.g. a lever mechanism.
If, as is preferred, a locking facility is provided e.g.
a key operated lock, this may be arranged to render the operation of the push button ineffective. A barrel-type lock may be arranged which, when locked, prevents the push button from being depressed through its normal operating stroke.
The retaining element may comprise a latch plate which is movable transversely, preferably perpendicularly, of the axis and path of travel of the plunger.
The plunger may have a recess in one side facing the latch plate and which receives the adjacent end of the latch plate which is then able to prevent axial movement of the plunger away from its withdrawn position. The handle therefore can be pivoted to and from angular positions close to its retaining position, without any impediment to its movement by the plunger. However, when the handle is returned from its release position and as it approaches the retaining position, the actuator element triggers release of the latch plate which allows the plunger to move rapidly under its biasing means to lock with the recess in the mounting plate when the handle reaches its retaining position.
The actuator element is preferably a fixed component on the mounting plate, and preferably exerts a progressive cam type of action on the latch plate to effect its release as the handle completes its return movement to the retaining position.

Referring now to the drawings, there will be described embodiments of actuator handle assembly for controlling the opening and closing of a closure member relative to a fixed frame in which the closure member is mounted e.g. an openable door or window in a respective fixed frame.
The actuator handle assembly has a mounting plate which will usually be mounted on a suitable part of a movable frame of an openable window or door, and a handle is pivotally mounted on the mounting plate for movement between a retaining position corresponding to a closed position of the door or window and a release position in which it permits movement of the door or window to an open position.
Figure 1 shows a perspective view of an actuator handle assembly according to the invention and which is designated generally by reference 1, and which comprises a mounting plate 5, and a handle which comprises a handle body portion 3 by which the handle is pivotally mounted on the mounting plate 5, and a hand grip portion 2 connected to and projecting from the body portion 3. A push-to-release button 4 is mounted on the body portion 3 and can be depressed in order to release the handle and allow it to be pivoted from a retaining position to a release position which will permit movement of the door or window to an open position. A barrel lock 6 is incorporated with the push button 4, and which can be rotated between locked and unlocked positions by insertion of a key (not shown) into slot 7 and by turning.The handle assembly can be secured to a window or door frame with standard fixings, such as screws or bolts, taken through holes 8 in the mounting plate 5.
When, as illustrated, the handle assembly is intended to operate a locking mechanism, a shaft 9 is provided which extends through the mounting plate 5, and which can be coupled drivingly with an input fitting of a window or door bolt locking system such as an espagnolette type fitting, whereby the actuator handle assembly is capable of operating the locking mechanism to lock the window or door in the closed position. Alternatively, although not shown, the handle may be a latching type of handle (cockspur or casement handle), in which case it will have a laterally projecting latching tab or nib (not shown) projecting from the body portion 3, and to latch with a fixed keeper plate on the fixed frame.
Figures 6 to 8 are detailed cross sectional illustrations of the internal operating components of the actuator handle assembly, and with the handle shown in Figures 7 and 8 in the retaining position corresponding to a closed position of the door or window, and with a plunger type locking system engaged between the body portion 3 and the mounting plate 5 (Figure 6 shows the handle in the released position). This comprises a plunger 20 which is slidably mounted in the body portion 3 for movement between a withdrawn position (shown in Figure 6) and a projecting position (as shown in Figures 7 and 8) with respect to the body portion 3 in which it has its lower end 22 held captive in a recess 23 provided in the mounting plate 5.
Further, biasing means in the form of compression spring 21 urges the plunger 20 towards the projecting position. When the plunger is in the projecting position, this retains or locks the handle assembly in the retaining position which will usually be the closed position of the door or window on which it is mounted.
To turn the handle assembly to the release position, it is necessary to disengage the projecting end 22 of plunger 20 from the recess 23, and this is achieved by depression of the button 4 which acts on a rocker arm lever 24 such that downward movement of the button 4 acts on one end of the lever 24 which produces a corresponding upward movement of an opposite end 25 of the lever, which also acts on a lateral protrusion 26 of the plunger 20 to lift the plunger 20 out of the projecting position to a withdrawn position against the action of spring 21.
The body portion 3 of the handle assembly also incorporates a retainer element in the form of a spring loaded latch plate or bar 27, which is movable between a retaining position and a release position with respect to the plunger 20, as shown in Figures 6 to 8, and which movement is in a direction perpendicular to the axis and path of movement of the plunger 20. The latch bar 27 is normally spring biased to the right so that it can be urged into engagement with the plunger 20 (after the latter has returned to its withdrawn position under the action of the push button 4, the lever 24 and interaction between lever ends 25 and protrusion 26). The spring loading of latch bar 27 is shown more clearly by reference 27a in Figure 6.Therefore, once the push button 4 has been operated, the plunger 20 no longer holds the handle body portion 3 captive with the mounting plate 5 and the hand grip portion 2 can be turned in order to unlatch and / or unlock any latch and lock fittings coupled with or associated with the actuator handle assembly.
Thus, in the illustrated embodiment, upon turning of the handle assembly, shaft 9 also rotates and operates a window or door securing mechanism, such as an espagnolette sliding bolt fitting. Movement of the hand grip portion to the release position therefore unlocks the door or window and allows the door or window to move to the open position.
As can be seen in Figure 6, latch bar 27 is spring urged to the right, and can latch in a recess 28 provided in the wall of the plunger 20, and therefore operation of the push button lifts the plunger 20 to the withdrawn position, and it is retained in this position when the latch bar 27 is spring urged into engagement in the recess 28. Therefore, upon release of the push button, the plunger 20 remains in the withdrawn position, and it remains in this position during opening movement of the handle, and also during the major part of the return movement to the retaining position, as described in more detail below.
However, as the handle returns to the retaining position, an actuator element in the form of cam type actuator 50 mounted on the mounting plate 5 engages automatically (directly or indirectly) with the latch bar 27 to move it against its spring loading 27a and out of latching engagement with the plunger 20, which releases the plunger 20 and allows it to be urged downwardly under the action of spring 21. This release takes place as the handle approaches the retaining position, and once the handle has reached the retaining position when the plunger end will be in alignment with the recess 23, it will move downwardly into captive engagement and thereby hold the body portion 3 rigid against rotation relative to the mounting plate 5.
As can be seen from the drawings, as the handle rotates about a mounting aperture 29 in the mounting plate 5, and returns to the retaining or closed position, the body portion 3 will overlie and therefore obstruct access to at least some of the mounting holes 8 in the fixing plate 5, and thereby prevent access to an intruder seeking to make unauthorised removal of the actuator handle assembly.
The construction shown in the drawings is one preferred embodiment of the invention, but evidently many other arrangements of the operating components of the handle assembly may be provided and within the scope of the claimed invention.
In particular, other types of lever construction may be provided to lift the plunger 20 out of the recess 23 and to the withdrawn position. Furthermore, other types of retainer or latch mechanism technically equivalent to locking bar 27 may be provided to retain the plunger 20 in the withdrawn position.
As described above, a barrel type lock 6 is incorporated as part of the push button 4, and may be of common barrel type, and is shown in Figure 8 in the locked position, whereby an abutment 30 of the barrel is located adjacent to an internal protrusion 31 within the body portion 3. In this position, downward movement of the button 4 is prevented, and therefore disengagement of the plunger or catch 20 from the mounting plate 5 cannot take place. The handle assembly is therefore locked tight. (Figure 6 shows the handle assembly in the released position in which free pivoting of the handle is allowed, whereas Figure 7 shows the handle in the retaining position (plunger 20 engaging in recess 23), but capable of being unlocked by depression of push button 4).
Figure 10 comprises a series of drawings a to e, which shows progressive release of the plunger 20 to be able to move downwardly under the action of spring 21, as the handle returns from its release position to the retaining position. Thus, upon closing the handle in the direction of the arrows 51, cam type actuator member 50 mounted on the mounting plate 5 engages cam follower 52 mounted on the latch bar 27 to cause the latter to become disengaged from its retaining position and engaging plunger 20, and initially spring 21 merely applies a downward force, but without downward movement of the plunger 20, and which is only able to move downwardly once it comes into registry with the recess 23 in the mounting plate 5. It then moves downwardly into captive engagement in recess 23 with the mounting plate 5.The latch bar 27 will be urged against its spring loading by the actuator member 50 and held in this release position for as long as the handle assembly is in the retaining or closed position.
Figure 7 is a further cross sectional view of the internal components of the handle assembly, and in this illustration the lock 6 has been rotated to an unlocked position, whereby the button 4 can be depressed to release the plunger 20.
It can be seen from the drawings that the plunger 20 housed within the body 3 of the handle 2, and the recess 23 in the mounting plate 5 are designed to be as far away as possible from the pivot point of the handle (the mounting in aperture 29 in the mounting plate 5) to reduce the leverage available on the plunger 20 and the recess 23 and thereby increase the load needed to be applied to the handle when unauthorised attempt is made to force open the handle assembly.
Referring now to Figure 11 this shows a further embodiment of actuator assembly according to the invention.
This is generally similar to the embodiment already described and illustrated, but in which the retainer assembly to retain the plunger has been removed. Therefore, the external sides of the back plate have a slope added local to the position of the plunger, and the sides of the plunger are radiused. This assist in the location of the plunger as the handle is closed.
