652185 Namre of Applicants: AUBREY JOHN SYMONDS, BARBARA ELLEN SYMONDS, GRAHAM JOHN SYMONDS, AVERYL JANETTE SYMONDS S Actual Inventor: *I AUBREY JOHN SYMONDS Address for Service: COLLISON CO.,117 King William Street, Adelaide, S.A. 5000 So Invention Title: RELEASE ARRANGEMENT Details of Associated Provisional Applications: No: PK2891 dated 18th October 1990 The following statement is a full description of this invention, including the best method of performing it known to us: L. 2 The invention herein relates to a release arrangement.

There are a number of situations where a door in normal use is locked by a person without the door needing to provide security, only privacy. One suchi example is a toilet door. However, the invention is applicable to other types of doors.

To illustrate, a typical problem encountered with such locked doors consider the situation where a person suffers a heart attack after locking such a door.

1 0 The person needing assistance cannot readily be reached because of the locked intervening door or the fact that the person collapses against an inside of the door thus necessitating the breaking or dismantling of the door which can be both difficult and possibly dangerous because of the time it can take to effect.

It is to such problems that the invention is directed. Of course this is not the only situation where such a door can be an obstruction in carrying out a necessary task.

CCr rI CC cL *1 It is an object of this invention to provide a quick release hinge and an arrangement using the hinge which will alleviate one or more of the aforementioned disadvantages or at least provide the public with a useful alternative.

The invention in one form resides in an arrangement by which a door is releasably supported to a door frame by a hinge means and a mounting plate means the mounting plate means releasably engaging the hinge means, a pin means biased to hold together the mounting plate and hinge means by cooperating apertures in the mounting plate and hv s means, the 3 0 pin means adapted to be externally accessible and releasable thereby allowing for separation of the mounting plate and hinge means.

Preferably, the door is supported by at least two hinges that are secured through externally accessible releasable means to the door frame.

f 1 I r.,

I

In preference, the hinge or hinges each comprise two leaves and a common pivot pin pinning the leaves, at least one of the leaves including a further member attachable to a respective part of either the door or the frame defining a doorway and releasably connected to the leaf by means that are S accessible even when the hinge .is in a closed position.

In another preferred form, the hinge or hinges each include a hinge plate detachably mounted to a member and held thereto by pin means that may be arranged in a locking or unlocking position by key means. A key is used I 0 to move the pin means from the locked to the unlocked position and vice versa.

f ft.

ft ft ft ft fttf Alternatively, the invention may be said to reside in a quick release hinge comprising a first plate member adapted to be fixed to a door hinge, the first I 5 plate member characterised by at least one aperture therein, a second plate member characterised by at least one aperture therethrough, the second plate member characterised by being adapted to co-operate with the first plate member in a dove-tail manner and thereby slideably engage one to the other, at least one pin member positioned by resilient means acting against 2 0 a portion of the second plate member to extend through the at least one aperture of the second plate and into the at least one aperture of the first plate member, the pin means further adapted to be externally accessible by a key means adapted to co-operate with the pin member or members to effect the movement of the pin member or members out of the aperture or apertures of the first plate member.

Preferably, the co-operation of the key means and the pin member or members is characterised in that a tapered rod is inserted into and through an aperture in the pin member or pin members to effect the movement of the 30 pin member or members out of the aperture or apertures of the first plate member.

In preference, the pin member or members are characterised by being protrusions and a key member is adapted to be inserted between the 3 5 protrusions and the second plate member and thereby permit the removal of the pin member or members out of the aperture or apertures of the first plate member.

4 In preference, the key means are adapted to reside in an aperture through the pin member or members and be shaped in cam-like fashion to effect in one orientation the insertion of the pin member or members into the aperture of the first plate means and in a further orientation the extraction of the pin member or members from the aperture or apertures of the first plate means.

To assist in the understanding of the invention described herein reference will be made to the accompanying Figures illustrating the invention as exhibited by preferred embodiments: FIG. 1 shows a perspective view of a first preferred embodiment of the invention, FIG. 2 illustrates in side elevation the quick release device illustration in FIG. 1, FIG. 3 is a cross sectional illustration of the quick release device illustration in FIG. 1 in the locking position along the plane as would be seen if the key was halved longitudinally and perpendicular to the major flat face of the hinge, FIG. 4 is a similar view of the quick release device as illustrated in FIG.

It will be understood that the invention is not intended to be limited by the specific form of the preferred embodiments.

1 5 The quick release hinge consists of a hinge 1 and a mounting plate 2. The mounting plate 2 is characterised by being slideably engaged with the hinge 1 by means of the dove-tail arrangement 3 and 4.

Mounted to the hinge mounting 2 is a pin 5 which is adapted to pass through a hole in the mounting plate 2 and into the hole 6 in the hinge.

The key 7 passes through the hole in the pin 5 and is supported by the mounting plate 2.

to, o 25 In FIG. 2 pin 5 is shown in its raised position for the sake clarity with the key 7 0 removed. The hinge of this embodiment would in use be characterised by the key 7 residing in a hole 10 of pin As can be seen in FIG. 2 the key 7 has a cam-like profile at 8 which when 3 0 inserted into the hole 10 of pin 5 determines whether pin 5 is protruding from the bottom of the mounting plate 2 or whether it is in the raised positi(n as S. illustrated in FIG. 2 and not protruding from the bottom of the mounting plate 2.

o i 3 5 A helical spring 9 is shown in FIG. 2 and is adapted to cause pin 5 to protrude through the mounting plate 2 unless prevented from doing so by the key 7.

L.

1 EM~i In FIG. 3 the quick release hinge is mounted to a door frame 12 and a door 11. The key 7 is shown in the locked position with spring 9 causing the pin to be protruding into the hole 6 through the mounting plate 3. Also illustrated in FIG. 3 is the wall 13 to which the door frame 12 is affixed and a rebate 14.

In FIG. 4 the key 7 has been turn so that the cam section 8 has forced, against the spring 9, the pin 5 out of the hole 6 in the mounting plate 3. This means that the mounting plates 2 and 3 can be separated.

1 0 Figures 5 to 12 inclusive illustrate a second preferred embodiment of the invention. The assembly is illustrated in Figures 5 and 6 with the parts thereof illustrated separately in the other drawings.

The assembly is made up of a hinge 15, a mounting bracket 16, mounting 1 5 bracket retainers 17 and 18, pin bracket 19, pin 5, key 7 and spring 9.

The hinge 15 is fixed to door frame 12 by screws. To the edge of the door 11 is fixed by screws the mounting bracket retainers 17 and 18. These hold mounting bracket 16 to the door 11. The mounting bracket 16 in conjunction with the mounting bracket retainers 17 and 18 hold the hinge 15 to the door 11. The co-operating parts of the hinge 15 are 20 and 21.

The hinge 15 and the mounting bracket 16 are held together by pin 5. Pin bracket 19 is adapted to protrude into holes 22 and 23 by influence of spring 25 9. The pin 5 is restrained by pin bracket 19.

Key 7 is placed through the pin 5 and pin bracket 19. By rotating the key 7 the pin 5 is removed from holes 22 and 23. Thereby the pin 5 can be selectively removed from a locking position and so the door 11 may easily 30 be removed from the door frame 12.

It will be appreciated that there are a number of variations and embodiments which can be constructed all exhibiting the invention. Whilst it is illustrated in FIG. 1 that the hinge is shaped to accept the mounting plate, an ordinary 3 5 hinge may have another specially shaped plate fixed to it and to which the mounting plate is attached.

i 7 It will also be appreciated that the key means illustrated can be varied. For instance the key means and the pin and spring arrangement can be configured such that when the key is removed from the pin the pin is in the locking position and sufficient of the hole through the pin is left above the surface of the mounting plate. Then the key being of a tapered shape can be inserted into the hole within the pin so forcing the pin to move out of the locking position and into the unlocking position so allowing the hinge and the mounting plate to be slid one from the other.

Alternatively the pin may be characterised by side protrusions running in line with the mounting plate and adapted such that the key means can be inserted between the protrusions and the mounting plate and so causing the pin to be moved from the locking to the unlocking position.

1 5 It will further be appreciated that a plurality of pins can be used on each side..

It will be appreciated that the invention as envisaged will provide a simple yet effective means to mount a hinge to a wall and to a door and yet provide quick means to dismount the hinge from the wall. Conversely the mounting plate may be affixed to the door instead of the wall.

15 Ao a a 0 t a0 o a o C s o 000o 0o 0 0 L+ +r ABSTRACT A quick release hinge suitable for mounting doors which are primarily intended to provide privacy is disclosed along with an application of the hinge. Use of the hinge allows the door to be easily removed even if the door is closed. The arrangement includes a door supported to a door frame by hinge means adapted to be releasable by means externally accessible to the hinge means. In a general form, the quick release hinge includes two hinge leaves joined together at a hinge pin. One of the hinge leaves is 1 0 fasten to a door, the other is slideably engaged into a plate fixed to a door frame. The leaf and the plate are secured by a pin protruding from the plate into an aperture within the leaf. The pin is resilienVy held by a spring within °o°0 the aperture but by application of a key may be removed from the aperture allowing the lea' and the door to be removed from the plate and the door o'o 5 frame. The key can take the form of a tapered rod adapted to be pushed into 0 or,,o a transverse hole within the pin and with co-operation of a bearing surface the pin can be moved against the spring out from the aperture. Alternatively a° 0 the key extends through a transverse hole in the pin and is shaped such that by rotating the key about the longitudinal axis the pin is move against the spring out from the aperture but in another position of the key the pin enters the aperture. 0 o a 0 0 O 0 B 1/8 4 0 0 4 0 tt* *00 *4 0 a 4q4* 44 1 0 g. 0 0 ~0 0 00 00 0 0 0 000 t4 A I t I I 4 009 0*0 no, 0 0000 0444 9 00 490 0 a oo 0 0 I 9a04 4 0 0109 0 0 44 0 004 C A, 9400 0004) 44 0 0 09 0 0 0 0 44 40 FIG 3 4/8 .1 0 0 1 09 0 212 SOI 13 4 0 t FIG 4 !1nj 00 00 00 0000 0* 22> 0 0 Fi I; -I I f q FIjG q *000 0 0*44 0004 o 0 Of 0 I 0 0* SSC CC,. *0~o* 0C~s 0400 Fi Ira 'p 8/8 S I S 0000 0000 00 flO 0 00 0 00 0 00 00 0 000 0 00 I I *0 II 0440 Otto 4114 O *0 0 044 0.4.4k FIii,i Fig -12
