Abstract
Description
- The invention relates to a lock apparatus, particularly to such apparatus as can be used in a multi-tenancy situation, in a theatre, cinema, sports stadium or the like.
- In such situations, including multi-tenancy premises such as a hotel, block of flats, apartments, student accommodation and the like, it is often necessary to provide a lock apparatus for a door or other closure, but which can be opened rapidly in an emergency or otherwise.
- It is an object of the invention to seek to provide such a lock apparatus.
- According to a first aspect of the invention, there is provided an apparatus for locking a closure such as a door, comprising a multi-point lock device, characterised by pivotable means operative to lock and unlock the lock device from the inside of a space normally closed by the closure.
- Thus using the invention it is possible to provide a lock apparatus in which the pivotable member is operable by pushing and on being depressed to unlock the closure, and to lock it on lifting.
- The pivotable means may comprise a push bar, or a pivotable push pad or pads.
- The pivotable means may comprise two spaced pivotable pads connected by a bar. This provides a relatively simple construction, which can be lifted or depressed for operation, particularly when each pad may have a recess in which respective opposite ends of the bar may be received.
- There may be an operating member on the outside (in use) of a closure operative to actuate the apparatus.
- The operating member may comprise a manually operable lever.
- The pivotable means may comprise a body mounted on an inwardly facing (in use) surface of the closure, and by a reciprocably slidable carriage or cassette operable by the bar, pad(s) or lever.
- The carriage or cassette may be mounted under pressure of resilient means to be biased normally to the unlocked condition. This provides a positive action.
- The bar or pad(s) may be pivotable about a pivot axis in a boss of the body.
- There may be a toggle or extrusion which may extends from the bar or pad(s) to operate the carriage or cassette.
- Suitably, the lock apparatus may comprise two multi-point lock devices which in use may be spaced apart across a closure and which are connected by the pivotable or push member. Thus in use when it is desirable or necessary to open the closure in say a 'panic' situation such as a fire, downward pressure on the push, or pad, member can unlock both multi-point lock devices simultaneously, as by the one pushing down or depressing action on the push member, the locking points of the multi-point lock devices are retracted simultaneously from their respective keepers to enable rapid opening of the closure, which could be a fire door, without the need for a key.
- The pad member or push pad may suitably comprise a bar or rod extending between, and connected to, slides of the multi-point lock devices which respectively carry lock members for engagement with, and release from, keepers on locking and unlocking the closure. Thus the push bar or rod will normally be on the inside of the door.
- There may also be means of the apparatus for locking said apparatus from the outside of the closure.
- The means may suitably comprise a lever device of the apparatus. The lever device may be an over-centre lever device which is assisted in passing to an over-centre position when the multi-point lock is locked by resilient means such as a spring which is carried in a slide and operable by the lever for example by a toggle or extension thereof. The slide is also operable by the push member.
- The lock apparatus can also be locked and/or unlocked by means of a key.
- It will be understood that the invention extends to a closure fitted with lock apparatus as hereinbefore defined, and/or a building including at least one such closure as hereinbefore defined.
- Apparatus embodying the invention is hereinafter described, by way of example, with reference to the accompanying drawings.
- Figs. 1 and 2 are respective schematic perspective views of a first and second embodiment of multi-point lock devices for use with apparatus according to the invention;
- Fig. 3 is a perspective schematic view of a door fitted with apparatus according to the invention;
- Figs. 3A and 3B are respectively schematic perspective views to an enlarged scale of the apparatus of Fig. 3, and a push pad for operation of the apparatus, both from inside a closure to which the apparatus is mounted; and
- Figs. 4, 4A, 5, 5A, 6 and 6A show to an enlarged scale respective longitudinal sectional views of part of the apparatus according to the invention.
- Referring to the drawings, there is shown in Figs. 1 and 2 respectively, schematic perspective views of quick-release multi point lock systems A, B of
lock apparatus 1. - The system A includes a bolt and hook locking arrangement C, the system B a bolt only locking arrangement D, there being a front plate P for the respective system A or B.
- There is in the embodiment an intermediate lock M which is key operable in the embodiment.
- The systems A, B are normally operable from the outside of a
door 6 to which they are mounted by means in the form of alever 18 to lock and unlock the closure. In order to provide quick-release of thelock apparatus 1 for a closure such as thedoor 6 there is on theinside 7 in use pivotable means in the form of a push member or push-bar device 8. The push-bar device 8 is a horizontal bar 8' (Figs. 3, 3A) mounted for upward and downward pivoting motion bypivots respective bodies 11. Thebodies 11 are at the opposite sides of thedoor 6. - The
keyhole 2 of the lock H is normally covered by thebar 8 and/orpivot 10, the lock M being intermediate the length of the plate P so as to provide atop bolt 3, acentral bolt 4 and abottom bolt 5, as shown in Fig. 2. The plate P with its plate P is mounted in a nose orfree edge 12 of thedoor 6 opposite an edge 13 about which thedoor 6 pivots for opening and closing on hinges or pivots (not shown). There can be a lock system A or B at both edges of the door. - Fig. 3B shows a
push pad 8", in the embodiment there being twosuch pads 8" linked by the bar 8' which is received insockets 8"' in each pad. - The plate 'P' which is longitudinally reciprocally slidable to effect locking and unlocking of the
multi-point lock system 1 is connected bysuitable connections 14 to a reciprocably slidable carriage orcassette 15 of thebodies 11 of the push bar device (Figs. 4 to 6A). The carriage or cassette is mounted in thebody 11 which is hollowed out at 16 to receive it and which is mountable under pressure of resilient or spring means 17 pressure to be biased to the open or unlocked position, being urged over-centre to lock thelock apparatus 1 either by lifting up thebar 8 or pad(s) 8" (there may be only one) from the inside of the door, or by moving an external operating member such as thelever 18 on the outside of the door. The pad(s) 8" is or are pivoted about apivot axis 19 in aboss 20 of thebody 11, there being a toggle orextension 21 of the bar 8', pad(s) 8" orlever 18 to slide the carriage or cassette. - As described, the
bodies 11 may each have a keyhole for key operation of the apparatus if desired, though a key is not necessary for operation of the apparatus. - In use, the
lock apparatus 1 being mounted with the push bar 8' on the inside of thedoor 6 and thelever 18 on the outside, on lifting the push bar 8' it slides the plate 'P' of the multi-point lock system to engage their locking points C for example behind respective associated keepers to lock the door. Likewise, operation of the lever from the outside of the door is such that lifting it over-centre also locks the door. When, however, the push bar 8' is depressed on the inside of the lockeddoor 6, all the locking points are instantaneously and simultaneously retracted and the door is openable without recourse to a key. - It will be understood that the two
pads 8" and bar 8' provide what could be termed a panic bar in that on downward pressure on the bar 8' orpad 8" in an emergency, a locked door is unlocked, the locking points C being retracted as the locking action is overridden, thus providing a fast egress multi-point lock. - Lock apparatus described herein with reference to the drawings thus incorporates the novel feature of having a push bar 8' or push pad or
pads 8" which can be operated from inside the door to lock the door on lifting, by actuating the multi-point lock to cause the locking points C to lock thedoor 6 and to unlock thedoor 6 on the push bar 8' or pad(s) 8" being depressed. The apparatus may operate left or right-hand opening doors.
