BACKGRO12ND C>F THE INVENTION Many door and windows, including those of bifold, winged, sliding and single unit configuration, Incorporate a bolting system to provide closure to doors or windows or enable selective positioning thereof. Many of such bolting systems function also in a security capacity.
However, the surface mounted or flush bolts that are presently available detract at once from otherwise presentable doors and windows. Housed bolts similarly, but to a lesser extent, present much metal to the eye because the operating levers and cover plates therefor remain exposed. Both of-these systems interrupt the door or window surface, gtvmg a mechanical appearance to a polished or enamelled timber. The metal fittings are prominent and it is not customary to give them the same colour as the body colour of the door or window.
From a security perspective, flush bolts are poorly adapted because typically they are merely checked into the face of the door or window and retained by a plurality of, and usually only three or four, small screws.
Furthermore, they usually employ a iever type action for bolt operation, and the normal functioning thereof causes a degree of mis-alignment between the bolt and bolt keeper during insertion of the former, which over time causes weakening of the connection between the door or window and the bolt system therefor.
-Flush bolts are also difficult to install because of the necessary precision required in preparing the door or window for fitting the bolt system so as to avoid door or window surface disfigurement. Housed bolts such as the common barrel bolt are an improvement from flush bolts, however, they are not representative of the ideal security system as still a large portion of the bolt system relies on mere screw attachment to the door or window and thus are more readily removable.
20OBJECT OF THE INVENTION It is therefore an objection of the invention to alleviate, at least to some extent, the aforementioned problems of the prior art, or at least provide the public with a useful attemative thereto.
OUTLINE OF THE INVENTION One aspect of this invention provides a door or window bolt system in which the working parts of the bolt systems are housed in the body of the door or window and the operating part is a surface mounted slide.
The slide may reciprocate in a slot of a surface mounted cover plate. The slide may be bistable in the operative and inoperative positions by spring assistance.
The cover plate is suitably decorative in appearance and is attachable to the door or window preferably by concealable attachment means, which most suitably attach to the inactive or closing edge of the door or window.
A bolt may ride In a pair of bores which are provided in the body of the lock which functions as the barrel in a conventional lock. The respective bores preferably extend between the door or window body and the door or window frame or header. The bolt may be arrested and released by a conventional key mechanism, preferably a lever lock or cylinder lock.
Preferably, the bolt system further includes door or window opening means, such as a ring pull. The ring pull may be disposed on said cover plate.
Suitably, the bolt system may be designed for flush or flanged fitment on a door or window.
The bolt system may be configured for lateral or vertical bolt reciprocation to suit the particular fixture, such as a ceiling, floor or adjacent wall, window or door frame, to which the door or window will be secured via the bolt system.
Preferably, said bolt system further includes a rebate provided for fitment in the recess of recessed doors and windows.
Preferably said bolt system further includes bolt positioning means, suitably in the form of a bolt keeper..
The bolt system should be suitable for all types of furniture applications, particularly doors and windows including timber, steel, aluminium, solid core, hollowed core, swinging, sliding, bifoid, latched, fire, sound, dust and security doors and windows.
BRIEF DESCRIPTION OF THE DRAWING Certain embodiments of the invention are now described with reference to the accompanying drawings in which:- Figure 1 is a perspective view of an upper section of a door incorporating the bolt system according to a preferred aspect of the invention with the bolt thereof extended in a locking position; Figure 2a is a cross sectional view, and Figure 2b a partial front view, of the door illustrated in Figure 1 showing the working parts of the bolt system with the bolt extended to secure door relative to header ; Figure 3b is an enlarged showing of different bolt types for use with the bolt system of the invention ; Figure 4a is a cross-sstional view showing a further embodiment of the bolt system according to the invention including locking means.
Figure Sa comprise perspective views of the bolt system of Figure 4a Installed on a door : Figures 6a and 6b illustrate the installment of bolt systems according to further preferred embodiments of the invention on the dosing side edges of different door types ; Figures 7a and 7b illustrate the installment of the keeper plugs to further preferred embodiments of the invention to the bolting in place of a door or window into fixed position to the said jamb site.
Referring now to the drawings, wherein like reference numerals designate like parts throughout the several views and embodiments, and initially to figure 1, there is illustrated an upper section of a door 10 fitted with a bolt system 12 in accordance with a preferred embodiment of the invention, wherein the operating part of the said system is visible and comprises a surface mounted slide 14, and the bolt 16 is shown to extend from the door 10 in a locking position.
As further illustrated in Figure 2a, the working parts of the bolt system 12 are housed in the body of the door which closes to header 18. For simple installation of the bolt system, a hole saw is used to provide a bore 20 in the body of the door to enable face plate 24 with bolt operating mechanism to be checked into the door, whereas a spade drill is used to create the bolt bore 22 by drilling a diameter hole, in this case extending down from the top of the door to intercept the former bore at 90 degrees so that the bolt can be inserted and screwed down onto the mechanism of the bolt system. This bore is extended partially into the overhead door header 18 in which the top end of the bolt is housed to secure the door or window in position.
Plate 24 is secured to the face of the door covering the bore 20 (as shown more clearly in Figure 2b). The plate has an integral bolt slide 26 which supports the bolt 16 in the bolt bore 222. A slide 14 rides vertically within a recess 28 in the plate 24. A pin 30 extends from the slide 14 into the door body to engage bolt 16. A dome 32 is slidably fitted on said pin and is urged against either of ramp faces 34 or 36 by a spring 38 biassed in order to give bistable positions to the bolt.
When slide 14 is moved to the upper position in said recess 28 and dome 32 is urged against ramp face 34, bolt 16 moves into bore 40 securing the door 10 relative to the header 18 as illustrated.
To release the door 10 from header 18, slide 14 is moved to the lower recess position with dome 32 being urged against ramp face 36, thereby retracting the bolt 16 into the door body.
To facilitate installation, the bolt is manufactured with accessory components as show~ 3a and 3bJfi0h reference to Figure 3b the two parts comprise X engaging part 4Wand a lower receiving part 44, uressaid parts being threadably connectable via respective male 46 and female 48 members. Threading can be adjusted to manipulate the length of the joined bolt parts to suit the particular door or window. Also, the bolt may be cut to adjust its length, or altematively, the position of the bolt system on the door or window adjusted to suit the Figure 3b. Where the bolt system is used on a relatively high door, ar the system is to be inserted at a substantially lower position on a standard sized door, the standard upper engaging part 42 illustrated in Figure 3b can be substituted with upper engaging part 50 which has an elongated male member 46 as represented in Figure 3b.
Referring now to Figures 4 and 5 there is illustrated a bolt system according to a further preferred embodiment of the invention, said bolt system incorporating locking means and being installed with attachment means hidden from view and the security of the ramp face in the door.
Referring firstly to Figure 4a, the bolt system 12 and parts thereof are shown installed in a door wherein the bolt 16 is in the extended position inside header 18 with the locking means, shown in the form of a key look 52, providing a secure closure by selectively arresting the bolt 18 in position.
The locking means 52 includes a lock plate 54, which covers bore 20, extending from the door surface into the body 56 of the door, the plate being fixed in position by screws 58 (see Figures f a and 5kb br details) inserted into the closing edge of the door so as not to detract from the presentation of the door face and security hold to ramp face in the door. A key 60 is adapted to be received into a key hole 62 in a key barrel 64 which extends through plate 54 into door body 56. Depending on the direction of key turning within the barret, an arrester 66 is moved either in or out of engagement with a notch 68 in the bolt 16. When the notch is engaged the bolt is arrested and the door can be locked in position. When the notch is disengaged or released by key turning in the opposite direction, the bolt can be moved between its respective extended and retracted positions by manipulating slide within recess 28 of catches R 34 br-34 when sliding cover is in the upper or lower sections of recess respectively to secure the bolt in position.
Referring now to Figure 6a and 6b installation of a preferred bolt system 12 on the closing side edges of different door types is shown. In the case of Figure 6b, the door is recessed at 104 to ensure the installed bolt system and particularly slide 14 lies flush with the extended door portion 106. A rebate plate 108 is overlayed on said bolt system in said recess and screwed in position via screws 110.
As depicted 7a and 7b is the installment of the keeper sleeve plugs (9-10) The door 2 is closed to the position required in the jamb head (1) which the said bolt stem (4) and the head of the stem (6) is pencil tipped to point and (7) the bolt stem is forced upwards into the jamb head (1) to mark the drilling point (3). Figure 7b relates to the spade drill bit (8) which is placed in align to indent in jamb head (1) to bore diameter hole (11) to install sleeve plug (9).
In reference to (Fig 8.9. 10. 11. 12.13) is the said model keyed one side and manually operated form the opposite side by way of slide button (Fig 10) is the face plate which has a known barrel casing 17 and known keying cylinder 18 incorporated into face plate shell-15 and in reference to (Fig. 8 a known key 8 is turned left to lock 130o and right from Oo deg. To 130o unlock (Fig 9) A-B (Fig 13) is a 3 dimensional view of gear 10 and (Fig 11) a through view of (Fig 8) part assembled in relation to (Fig 10) which shows components side on view and face on view.
Referring now to the gear 10 and cam 9 with gear arm of cam 24 which leavers the gear detail (Fig 9) A-B the gear 10 is partly housed out to half diameter shown (Fig 13) a 28-29 this allows return of cam 9 and leaver of cam 26 to return to retrieval of key 8 to Oo this also allows the gear to be free and independent of locking cylinder (Fig 10) 18 in which the gear 10 can rotate freely on the said bolt stem (Fig 8) 26 of up to lock and down to unlock by way of slide button 14 the opposite side of door 27.
Now-to installing process part (5) show a 19mm spade bit which is indicated as (step 1) as in the case of top or bottom edge of door drilled in 3mm to allow sleeve plug setting before proceeding with (step 2) which a 16mm auger bit is used to bore out for bolt stem this also determines back set depth (fig 1)-1 to flange mount the device as shown (fig 2) using a 22mm spade bit-2 drilling a series of holes shown to install mechanism (fig4). To flush mount the device shown (fig 3) is to use a 25mm spade bit 3 before drilling back set (fig 2)-2 to let in face plate as in the case closing edge of the door or face of door.
10 We have found the advantages'of the embodiments of the invention to include : - (i) Easy preparation of a door or window for installation of the bolt system; (ii) The unobtrusive appearance of both the slide and key lock plates; and 15 (in) The incorporation of a locking means to immobilize the bolt.
Whilst the above has been given by way of illustrative example of the present invention many variations and modifications thereto will be apparent to those skilled in the art without departing from the broad ambit and scope of the invention as herein set forth.
