Description

HANDLE

Field of the Invention

The present invention relates to a swing handle assembly, comprising a swing handle member and a supporting frame therefor and a capture means, In particular, the capture means is able to cooperate with a separate or independent securing means, which securing means may be selected by the user, to place the handle assembly in a locked condition.

Background of the Invention Swing handles have become popular because of their simplicity of function and because they can be made to fit substantially flush, against a surface and thereby reduce the likelihood of injury to passers by. Accordingly, swing handles have found wide-spread acceptance as the door handle of choice on access points such as on transport vehicles and the like; housings for computer equipment for which controlled access is desirable; and for where entry is required to a high security area.

In circumstances requiring high security, it is necessary to lock a swing handle .in a closed condition. Some previous swing handles incorporate a locking mechanism in. the handle member, which mechanism engages with the cooperating supporting frame or door upon which the swing handle assembly is mounted. However, such swing handle assemblies are necessarily sold with the locking mechanism incorporated, potentially limiting the choice of locking means to be used by the end user.

The present invention therefore seeks to provide a lockabie swing handle assembly for use with a separate securing means, which securing means can be selected by the user, which assembly seeks to substantially ameliorate or minimize the disadvantages of the prior art.

Summary of the Invention

According to the present invention, there is provided a swing handle assembly comprising a swing handle member and a supporting frame therefor., whereby when the handle member is in substantial contact with the frame, the handle assembly is in a closed condition, wherein; (i) the handle member comprises at least an outer surface and two side walls, each side wall including an opening therein wherein the openings are substantially aligned to define a passageway through the handle member; and

(ϋ) the supporting frame bears a capture means, which capture means is substantially receivable within the handle member and is in substantial alignment with the passageway therethrough when the handle assembly is in the closed condition, such that to then place the handle assembly in a locked condition, a separate securing means is able to be passed through the passageway and the capture means.

Preferably, the capture means is a shackle fixed to the support frame. In some forms of the present invention, the capture means is integral with the supporting frame. In other forms of the present invention, the capture means is fixable to the supporting frame via an attachment means. The present invention provides the user with a choice as to which separate securing means is used to lock the swing handle. For example, the end user may choose to use a separate standard key or combination padlock which can be fitted to a swing handle member of the assembly of the present invention to provide the or additional security.

Preferably further, the hanόle member comprises an open box-like body configuration, wherein the side walls are substantially perpendicularly disposed towards the outer surface, an. internal space being defined therebetween, wherein the capture means is substantially receivable within the internal space of the handle member, when the handle assembly is in the closed condition,

In order to reduce the likelihood of causing injury to passers-by, the capture means preferably does not substantially protrude above the outer surface of the swing handle member.

The handle member is preferably of a substantially complementary shape to a recess within the supporting frame to allow the handle member to be receivable within the recess. Preferably further, the recess of the supporting frame is defined by at least one side wall/s and opposed end walls, wherein the or each side wall/s is each provided with a cut-out region which, acts to expose the passageway when the handle assembly is in the closed condition. The side walls and end walls also prevent unauthorized opening of the swing handle assembly by a potential intruder by impeding insertion of a lever between the supporting frame and the swing handle member. As used herein, the term "open condition" refers to the swing handle member being lifted out of contact the supporting name whereafter the swing handle may be rotated relative to the supporting frame. An example of "open condition" is illustrated in FIG.1. In contrast, the term "closed condition" refers to the swing handle member being in substantial contact with the supporting frame and more preferably, parallel with the supporting frame and seated substantially in the recess of the supporting frame. That is, the swmg handle member is lowered substantially into and substantially received within the supporting frame. An example of "closed condition" is illustrated in FIG.2.

In certain embodiments of the present invention, the swing handle assembly may further comprise an engagement means, wherein the engagement means releasably engages the swing handle member with the supporting frame when the swing handle assembly is in a closed condition.

The engagement means can be as simple as relying upon a snap- or quick-fit engagement or even magnetic attraction, between associated parts or through a friction fit. The snap- or quick-fit engagement means preferably comprises a suitable female member positioned on the floor of the supporting frame or, in an alternative embodiment, on the underside of the swing handle member. The snap- ox quick-fit engagement means further comprises a male member which is releasably receivable within the suitable female member, and which is located on the underside of the swing handle, or in the above alternative embodiment, on the supporting frame. In a preferred form, when the female member is positioned on the underside of the swing handle member;, the position of the cooperating male member is aligned therewith on the supporting frame. However, when the female member is located on the supporting frame, then the male member is aligned with and positioned on the underside of the swing handle member. The male member can be as simple as a threaded fastener having a suitably shaped head. The female member preferably comprises a substantially obconic recess formed within a suitable receiving means and into which recess the male member is able to be releasably received and held. The male member, preferably a threaded fastener, can be releasably secured to the supporting frame. When the female member is positioned on the supporting frame, it can be releasably secwed thereto via a suitable fastening means such as a threaded bolt, preferably having a countersunk head_* which bolt is receivable within the recess and is thus able to be screwed and held onto the supporting frame. Instead of the snap- or quick-fit arrangement, one or more, preferably a pair of, suitable magnets may act as engagement means. One or more of these may be provided and affixed to the relevant underside of the swing handle member and as a plate affixed to the floor of the supporting frame. In a friction fit arrangement, the provision of grub rubbers which can be affixed to the inside surface of a chamber and/or to an aligned region on the swing handle member to hold the swing haadle member in factional contact with, its supporting frame. The engagement means may incorporate a combination, of these preferred arrangements.

As is common with swing handle assemblies, the swing handle member is preferably co- operable with a locking shaft and is pivotal about the locking shaft relative to the supporting frame. Such an arrangement allows the swing handle to be used to xotate devices attached to the locking shaft. Accordingly, such devices may be used to secure doors and the like.

In certain embodiments of the present invention, the swing handle assembly may further include a biasing means acting on the handle member, which biasing means ensures that, unless physically urged downwardly into the supporting frame, the handle member will be urged towards an open condition, that is, the handle member will be in a raised position above the supporting frame. In this way, it will be readily noticeable if the handle member has not been secured to its supporting frame.

The biasing means is preferably located between the locking shaft and the swing handle member, such that when the biasing means is in a relaxed condition, the other end of the swing handle member is maintained substantially out of contact with the supporting frame, enabling an observer to note that the swing handle member is not in lockablc engagement with the frame. The biasing means is preferably a spring, wherein the spring comprises a coiled spring having a first and a second end. and a passageway formed through the coil windings thereof.

A benefit derived from such, an arrangement is that when the swing handle assembly is in the unlocked condition, the swing handle member will remain in a substantially raised position relative to the frame and will therefore be readily noticeable to the user/observer that the swing handle assembly is not locked and that in the event that the swing handle member is dropped or accidentally let go of, the biasing means acts to substantially prevent the other end of the handle member contacting the area immediately surrounding the supporting frame. In addition, the handle member will remain in the raised position, until positively acted upon by a downward force. Preferably, downward pressure applied to the outer surface of the swing handle member causes the other end of the handle member to be lowered into the frame, and causes the biasing means to be placed in a substantially compressed condition, whereby the first and second ends of the spring are brought into substantial juxtaposition to one another. Should the applied pressure be removed, the biasing means will return to a substantially relaxed condition, thereby returning the swing handle member to a substantially raised position above the supporting frame and thus above the surrounding area to which the swing handle assembly is attached..

The present handle assembly lends itself to cooperation with, a separate securing means such as, but not limited to, a padlock mechanism. The padlock mechanism comprises a lock body member; a lock hasp; and the usual latching mechanism accommodated in the lock body member, as is known in the art. The latching mechanism enables latching of the hasp to the lock body member. The latching mechanism releases at least one end of the hasp on an opening actuation of the latching mechanism, whereby one end of the hasp can be swung away or removed from inside of the lock body member. When being fitted to the swing handle assembly, the unattached hasp end of the padlock can be fed through the aligned capture means and passageway on the swing handle assembly and then latched to the lock body member. Once latched, the swing handle assembly is placed in the locked condition.

In order for the swing handle assembly to be placed in the unlocked condition, at least one end of the hasp is released from the aligned capture means and passageway on the swing handle assembly. Once the padlock has been disengaged from the swing handle assembly, it is the engagement means of the present invention (if present) that retains the swing handle assembly in a closed condition if a biasing means is present that would otherwise urge the handle member out of substantial contact with the supporting frame and to a substantially raised position thereabove. The handle member may be raised, from out of its supporting frame and rotated to open the access point. The skilled addressee will recognize that alternative separate securing means may be employed that function in a manner similar to the padlock described above.

The scope of the present invention, further extends to a swing handle assembly as described above being substantially receivable in a dish, The dish, which is substantially the means for mounting the swing handle assembly into or onto the surface of a door, cover or hatch and/or the like, is preferably suitably shaped to at least partially accommodate the swing handle arrangement of the present invention therein. The dish may be suitably configured to also permit at least part of the separate securing means to be accommodated therein. For these purposes, the dish preferably has a pair of opposing side walls. Preferably, each set of side walls extend from and diverge outwardly relative to the dish floor to end in the perimeter flange, which flange is substantially outwardly directed The depth of the recessed area can be varied such that the height that a padlock mechanism might normally protrude above the mounting surface can be substantially reduced, thereby making it less prone to injuring passers by. The dish is more preferably of a substantially rectangular configuration.

In one preferred embodiment, the dish, is formed integral with the supporting frame such that the dish becomes the supporting frame and the swing handle assembly of the present invention is then attached to the dish at a later stage in the manufacturing process. Ia. yet another preferred embodiment, the dish is manufactured separately with the swing handle member and its supporting frame subsequently attached thereto.
