Abstract

A self locking closure device (10) for an opening light (15) of a window comprises a cylindrical base part (11) attached to the sub-frame (14) of the opening light (15) and having a bore (16) in which is rotatingly received the cylindrical body (15) of a handle part (12). A handle (20) and a latch (21) angularly displaced therefrom, extend laterally of the head (19) of the handle part (12) and a plunger (26) extends along an axial bore (22) in the handle part (12). A locking pin (36) slides in laterally extending axially aligned bores (34, 35) in the base part (11) and the body (15) and is biassed by a spring (37) into contact with the plunger 26. With the opening light (15) closed the plunger (26) must be depressed against a spring (31) to cause the locking pin (36) to move inwardly out of lateral bore (35) in the base part (11) and allow rotation of the handle part (12), thereby releasing the latch (21) from a latch plate (32) attached to the window main frame (33). When the opening light (15) is closed and the handle part (12) returned to the securing position the spring (31) pushes the plunger (26) so that an enlarge part (27) thereof pushes the locking pin (36) into the lateral bore (35) of the base part (11) to secure the closure device (10) in the securing position. <IMAGE>

Description

SPECIFICATION Closure e ce This invention relates to closu re devices and' in particularto devices for closing and securing windows.
It has been customary for many yea rs to attach a window stay to each of the windows in a home. Such a stay serves as a handle for pushing open and pulling closed the window, for locating the window in an open position and for securing the window in a closed position. Forsecurity reasons it is known to provide a catch mechanism which engages the stay when in the closed position and must be released before the window can be opened.
In the case of more modern double glazed aluminium, UPVC and/or hardwood window structures, it is conventional to provide friction hinges/stays which locate the window in any desired open position, and to provide, forthe purpose of securing the window in the closed position, a simple handle/latch device. Rotation of such a latch handle, which is mounted on the opening window, to the window securing position causes an arm or spigot to engage a latch plate secured to or recess in the fixed frame surrounding the opening window. Again for reasons security it is known to provide a locking device in the latch handle so that the latch handle cannot be turned and the window opened unless the lock device is an unlocked condition.To change the lock device from a locked condition to an unlocked condition orvice-versa requires the use of a key or tool. Although such arrangements are perfectly satisfactory in them- selves, in practice many people are only motivated to lock all ofthe windows in a house when they know that they are to be absent from the house for a considerable period, for example, for a weekend or extended holiday. Many people do not botherto go round the house and lock every window if they are to be out of the houseforaveryshorttime,forexample,when shopping orevenwhentheyareto be in the house but not moving about fro room to room, for example at nightwhen they are in bed.In addition, if all ofthe windows are not fitted with matching locks, several different keys may be required. In consequence, unless all of the windows are locked on every such appropriate occasion, there is little point in providing the locking devices.
It is an object of the present invention to provide a locking closure device whereby a window may be secured in a closed position, butwhich is not subject to the abovementioned deterrent effect as regards its regular use is concerned.
The invention provides a closure device adapted to be secured to an openable window or the like, said closure device comprising a handle part movable relative to a base part between windowopening.and window securing positi.o.rrs, said, h-a n.dl part having; ai latch part, and further comprising manually reteasabl,e lOC8Ftg rRearrs epeFableto sS*Fe saL handle part againstsaid movementfrom said window securing position. towards said window opening position, said movementofsaid handle partfrom said window opening position to said window securing position causing said locking means to secure said handle means.
The invention also comprisesawindow having a mainframe, an opening lighthaving asub-frame pivotally attached to said mainframe and a closure device comprising a base partsecuredto said sub-frame, a handle part attachedtosaid base part and movable relative thereto betweenwindowopen- ing and window securing positions, said handle part having a latch part engageable with said main frame when said opening light and said closure means are in the window closed position, and said closure means further comprising manually releasable locking means operable to secure said handle part against said movement from said window securing position towards said window opening position, movement of said handle part, said movement of said handle part from said window opening position to said window securing position causing said locking means to secure said handle means.
The invention will now be describedwith reference to the accompanying drawings, in which: Fig. is a sectional side elevation of the closure device in the window securing position, Fig. 2 is a front elevation of the closure device of Fig.
l,and Fig. 3 is a sectional side elevation of the closure device in the window opening position.
The figures show a window closure device 10 comprising a base part 11 and a handle part 12. The base part 11 is secured by screws 13 to a sub-frame 14 of opening light 15. The base part 11 is of generally cylindrical form and has a bore 16 which is counterbored at 17to a larger diamter. The handle part 12 comprises a cylindrical body 18 which is received and is rotatable within the bore 16 ofthe base part 11, an enlarged cylindrical head 19 which is integral and coaxial with the body 18, a handle 20 extending laterally ofthe head 19 anda latch 21 also extending laterally ofthe head 19 but angularly displaced from the handle 20.A bore 22 and enlarged counter-bore 23 extend axiallythrough the head 19 and body 18. The end ofthe counter-bore 23 remote from the head 19 has a screwthread into which a large headed screw 24 is received. The head 25 of screw 24 is of large diameter than the body 18 and bore 16, and is received in the counter-bore 17 so asto retain the handle part 12 in the base part. A plunger26isasliding fit in the bore 22 and has one end extending therefrom. Atthe other end of the plunger 26 isan enlarged head 27 which is sliding ivy received inthe counter-bore 23. The transition region 28 of the plunger 26 between the stem part29 andthe head 27 isof conicalform andthe transition region 30 between the bore 22 and counter bore 23 inthe handle part 12 is of corresponding conical form. Acompression spring 31 is located between the head 27 of the plunger 26 and the screw 24 so asto bias the plunger 26 into the position shown in Fig. 1 with the transition regions 28,30 in mutual contact.
A latch plate 32 is secured to the main frame 33 of thewindowsothatwhenthe opening light 15 is in the closed position with its sub-frame 14 abutting the mainframe 33, the latch 21 is retained "in front" of the latch plate 32 to prevent opening of the opening light 15. Aiigned bores 34,35 are provided in, and extend transversely of the axis of, the body 18 and base part 11, and a two-part locking pin 36 is received in the bores 34,35. A compression spring 37 is located between the top of the pin 36 and a retaining screw 38 which is screwed into the bore 35 in the base part 11.
The spring 37 serves to bias the pin 36 into contact with the plunger 26.
When the opening light 15 and closure device 10 are in closed position shown in Figs. 1 and 2the pin 36 is in contactwith the head 27 ofthe plunger 26 and the mutual contactface 39 ofthetwo parts ofthe pin 36 is within the bore 35 in the base part 11. In this case the longer lower part of the pin 36 prevents rotation of the handle part 12 relative to the base part 11,and in consequencetheopening light 15 cannot be opened.
If the plunger 26 is depressed into the handle part 12, it will move to the window opening position shown in Fig. 3. In this position the pin 36 is force by spring 37 downwardly in the bores 34,35 to contact the stem part 29 of the plunger 26. In consequencethe mutual contact face 39 moves into alignment with the surfacesofthe body 18and bore 16, and the body 18 can rotate relativetothe base part 11. The handle 20 can therefore be moved downwardlyso that the handle part 12 rotates to the position shown in Fig. 3 with the latch 21 out of contact with the latch plate 32.
The opening light '15canteen be opened.
On closing of the opening lig ht 1 the handle 20 is moved back to the position shown in Fig. 1 so that the latch 21 is in contact with the latch plate 32. the two bores 34,35 willthen be re-aligned so that the pin 36 can move outwardlytherein. The spring 31 is suffi cientlystrongtoforcethe plunger 26 back tithe position shown in Fig. 1, this in turn forcing the pin 36 to moveoutwardly in bores 34,35 by rising up the conical transition region 28 againstthe lesserforce of the spring 37. This returns the closure device 10 to the window securing position. The opening lightl 5 is effectively locked in the closed position sincethe handle 20 cannot be operatedto release the opening- light 15 unless the plunger 26 is depressed. This prevents a would-be intruder from successfully pris ing a screwdriver or liketool between the sub-frame 14 and the mainframe 33 to lever against and move the handle 20 and release the opening light 15.
With the configuration shown, asthe hand reaches to grip the handle 20,thethumb may readily be placed overthe plunger 26to depress it and allow rotation of the handlepartandthe opening of the opening light 15.
