Figure 9 is a plan view of a back plate forming part of an opening restrictor according to the present invention; -
Figure 10 is an elevational view of a hollow cylindrical fastener forming part of an opening restrictor according to the present invention; and -
Figure 11 is a perspective view of an alternative embodiment of the securing lever shown inFigure 7 . - The opening restrictor shown in
Figures 1 and 2 comprises a body portion 1 which is releasably connected to a securing bracket 3 by way of aconnecting means 5, for example in the form of a cable. The securing bracket 3 as illustrated comprises a window handle bracket which is secured to an opening window (not shown), although a bracket in the form of a door handle plate can be used with a door. - The securing bracket 3 is made, for example, of stainless steel and includes a substantially planar
elongate portion 7 which in use is positioned between an opening member, such as a door or window, and a conventional means, such as a window handle or a door handle, for controlling opening and closing of the opening member. The elongate portion of the securing bracket is provided withapertures 9 to allow the passage of fasteners provided for the window or door handle. Thus no additional fasteners are required to secure the cable 3 to the opening member, while the cable is secured to the opening member in an effective and aesthetically pleasing manner. The securing bracket 3 also includes aportion 11 which extends in a direction away from the opening member, for example substantially at right angles as illustrated. Theportion 11 is attached to theelongate portion 7 and is provided with an aperture 13 (shown more clearly inFigure 3 ). An alternative configuration of securing bracket, for example for use with a door handle mounting, is shown inFigure 4 . - The
cable 5 may include a length of conventional flexible steel cable provided with a covering of plastics material. A plug 15 is secured, for example by crimping, to one end of the length of cable and may be made, for example, of stainless steel. The plug 15 is then made captive through theaperture 13 in thebracket portion 11. Ideally, in use the head of the plug 15 is positioned close to part of the opening control means, ideally a non-moving part thereof, so as to restrict access to the plug 15 to minimise the likelihood of tampering. Afurther plug 17 is secured to the other end of the length of cable, for example by crimping, for releasably securing to the body portion 1. Thefurther plug 17, shown in detail inFigure 5 , is formed with a profiledportion 19 and arounded end 20, which enable thefurther plug 17 to be releasably secured to the body portion. As illustrated, the profiledportion 19 comprises an annular recess formed around the periphery of theplug 17. - The body portion 1 includes a body 21 (shown in more detail in
Figure 6 ), for example of die-cast aluminium, into which alock 23 is secured. Thebody 21 is formed with twoopenings openings caps 29, 31, for example of Nylon, which are ideally profiled to match the profile of thebody 21. Thecaps 29, 31 inhibit access to the fasteners and prevent tampering therewith. - The
body 21 is also formed with alateral opening 33 dimensioned to receive thefurther plug 17 of thecable 5. Asecuring lever 35 is pivotally mounted within thebody 21 and extends across an opening 37 in which thelock 23 is received. As shown in more detail inFigure 7 , the securing lever is formed with anaperture 39 in one end region thereof for mounting the lever in a pivotable manner by way on asecuring pin 41, and is formed at the other end thereof with anengaging portion 43 for engaging with the profiledportion 19 of thefurther plug 17. An outer edge of theengaging portion 43 is formed with achamfer 45 such that insertion of therounded end 20 of thefurther plug 17 causes thelever 35 to pivot from a first position to a second position and to allow theplug 17 into thelateral opening 33. Thelever 35 then returns to the first position under the influence of a biasingspring 47 so as to lock the further plug in the body portion 1. - An alternative securing lever is shown in
Figure 11 and functions in essentially the same manner as the securing lever ofFigure 7 . - The biasing
spring 47 is shown in more detail inFigure 8 and comprises asheet 49 of resilient material, such as spring steel, formed with a tongue 51 at an angle to the remainder of the sheet and directed towards thesecuring lever 35 so as to bias theengaging portion 43 into the profiledportion 19 of thefurther plug 17. Thebiasing spring 47 is maintained in position in thebody 21 by means of a back plate 53 (shown inFigure 9 ) which is secured in place by two hollow cylindrical screw fasteners 55 (shown inFigure 10 ) which engage in theopenings - In use of the opening restrictor according to the present invention, a key (not shown) is used to unlock the
lock 23. In the unlocked configuration, a body of the lock can be depressed into thebody 21 and is biased to return to an extended position. When the body of the lock is depressed into thebody 21, thelever 35 is pivoted to displace theengaging portion 43 out of thelateral opening 33 so as to disengage from the profiledportion 19 of thefurther plug 17. This allows thefurther plug 17 to be released from the body portion 1 and allows the window, door or the like to be opened fully. In the locked configuration, the body of the lock cannot be depressed into thebody 21 and thefurther plug 17, if present in thelateral opening 33, cannot be removed, therefore restricting opening of the window, door or the like. - When the
further plug 17 is not present in thelateral opening 33, the window, door or the like can be opened in an unrestricted manner. However, thefurther plug 17 can be inserted into thelateral opening 33 irrespective of whether thelock 23 is in its locked or unlocked configuration. In either configuration, therounded end 20 of thefurther plug 17 contacts thechamfer 45 of the engagingportion 43 of the securinglever 35 and pivots the securinglever 35 to allow thefurther plug 17 to enter thelateral opening 33 until the engagingportion 43 engages with the profiledportion 19 to retain the further plug in the lateral opening. If thelock 23 is in its unlocked configuration the lock body can be depressed to release thefurther plug 17, but if key has been used to move the lock to its locked configuration the lock body cannot be depressed and thefurther plug 17, and therefore thecable 5, is locked to the body portion 1.
