Description
~Z~i s'9~
FIELD OF THE INVENTION
This invention relates to a locking means for a closure, for example, a sliding or pivoting gate and door.
DESCRIPTION OF THE PRIOR ART
At present only a limited number of types of locking means for closures, for example, doors, gates and the like are available. The most common type of lock used on gates is, of course, a padlock used with either a latching mechanism or length of chain.
A recent innovation used in the security industry and developed in the United States of America uses as a key a plastics or metal card with magnetizable points impregnated therein. The key operates a locking device openable when a correct key card is inserted. The product is sold under the trade mark COR-KEY and was designed by Bruce Sedley of America, This key and its associated lock has a large number of combinations which depend on the orientation of magnetised points on the card and in the lock. The key card is usable with a lock operating device which has a ~ slot in an operating lever or member thereof. The operating member normally freely rotates when no card is in the slot. When a correctly coded card is inserted and the card pressed into the operating device the rotational movement thereof operates a latching mechanism of the lock. An incorrectly coded card when inserted in the slot allows the operating member to freely rotate without activation of the latching mechanism. The latching mechanisms with which the product has been used include electrical systems and most forms of mechanical door ~267~24 hardware.
An object of the presen-t invention is to provide a lock means for a closure, for example, a gate and door which lock means is inexpensive to manufacture and easy to install.
SUMMARY OF THE INVENTION
According to the present invention there is pro-vided a lock means and associated catch member for locating a closure member relative -to an abutment means. The lock rneans includes a lock operated latch bolt which is mounted within a housing. The housing has a hollow section, the ends of which are closed and the lock is arranged in the housing with the longitudinal axis of the la-tch bolt aligned with the long-itudinal axis of the housing. The housing has in the side thereof a slot which allows access to a space within the housing. The latch bolt moves longitudinally within the housing when the lock is released, between a locked position in which the latch bolt extends across the space in the housing and a open position in which the latch is retracted from the space in the housing. The catch member has at least one aperture therein and can extend into a space in the housing through the slot to co-operate with the latch bolt when in its locked position to locate the part of the catch member with the aperture(s) within the space in the housing and with the latch bolt extending through the aperture in the catch member. Each of the housing and the catch member is adapted for mounting on a respective one of an abutment means and a closure member (or visa versa) so that, in use, when the part of the catch member with the aperture therein is engaged with the slot in the housing, then movement of the ~i '`;
~Z6~9~4 latch bolt under the operation of the lock engages or dis-engages the end of the latch bolt with or from the aperture to lock or unlock the closure member from in juxtaposition with the abutment means.
The latch can operate a lock wi-thin the housing via a key card. For example, the card can be a coded magnetized card insertable in a slot in an operating member connected to move the latch.
The catch can be an arm, bar or chain which, in use, is fixed to the abutment means or closure member.
The abutment means can be any of a post, wall, frame and gate member adjacent to which the movable closure member is swun~ or slides.
The movable closure member can be any of a gate, door or other means adapted to pivot or slide into juxatposition -/ - 4a -,. `~ :' '' ~Z6792~
with the abutment means.
The catch member can be mounted relative to a first gate member and the housing mounted relative to a second gate adapted to move into juxtaposition with the first gate.
Further aspects of the present invention which should be considered in all its aspects will become apparent from the following descriptions.
BRIEF DESCRIPTIONS OF THE DRAWINGS
Examples of the invention will now be described with reference to the accompanying drawings in which:
Figure 1 shows a perspective view from the front of an example of locking means showing a catch member which operates therewith in a position spaced therefrom;
Figure 2 shows a side view partly sectioned of the locking means and catch member shown in Figure 1 with the catch member locked in association with the locking means;

Figure 4 shows a side view partly sectioned of the locking means and catch member shown in Figure 1 with the catch member engaged in association with the locking means;
Figure 5 shows a plan view of the locking means and catch member shown in Figure 1 and 2 or 3 and 4 located in position relative to a post or first gate and a closure member wherein the catch member is fixed relative to the closure; and ~67~
Figure 6 shows a plan view of the locking ~eans and catch member shown in Figures 1 and 2 or 3 and 4 locàted in position relative to a post and closure respectively wherein the locking member is free to pivot relative to its mounting.
DESCRIPTIONS OF THE PREFERRED EMBODIMENTS
In the examples the locking means will be described with reference to its use in a situation where it is used to lock a pair of gates together. It is to be appreciated that with minor modifications the invention can alternatively be used to lock any closure member relative to an adjacent post, wall, frame, or abutment member.
The locking means as shown in Figures 1 and 2 has a latch bar 1 mounted within a housing or locking block 2.
The housing 2 is formed from a length of rolled hollow section (RHS) steel with plates covering the top 3 and bottom 4 respectively or from lengths of channel section the ends of which are closed by plates welded into the ends of the channel sections. In a configuration where the ~ housing is a length of RHS the plate covering the top 3 is preferably welded into position whereas the plate covering the bottom can be removed to allow access to the interior of the housing 2 for maintenance and repair purposes. When the housing is formed from two lengths of channel section the two halves are fixed together by fixing means extending between the back and front face of the housing. The front of the housing 2 has a transverse slot 5 therein and an operating member 6 thereon. The operating member 6 ~Z67~
being operable by a plastics key card with a magnetized code therein or thereon. The key card being inserted in a slot 7 in the operating member 6 which is normall~v free to rotate relative to cover 8 which is fixed to the front of the housing 2 and within which is an operating linkage (not shown) which activates a lock 15 within the housing 2 and from which the latch bar 1 can extend. The rotation of the operating member 6 with the key card inserted, providing the code is correct, operates the lock 15 to move the latch bar 1 to its open or closed position. If the incorrect key card is used the operating handle 6 continues to freely rotate and the latch bar 1 remains stationary.
The lock 15 can be fixed within the housing 2 by fixing means 16 extending between the bottom 17 of the lock 15 and threaded holes 18 in the top 3 of the housing 2.
The lock 15 shown in Figures 1 and 2 is a lock of the type which when in its down position (Figure 2) acts as a dead bolt. The latch bar 1 has in association therewith an activating rod 19 which normally moves with the bar 1 unless it is retained in its raised position (Figure 2) in which the lock 15 acts as a deadlock.
In practice the code of both key cards and the operating member 6 within the cover 8 can be easily and quickly changed by use of a proprietary tool which is designed to change the magnetized lay out on the key card and the lock cylinder which is within the cover 8.
The locking means operates in association with a catch member, arm or bar generally indicated by arrow 9.
~i7~2~
The catch member 9 can be mounted in a number of ways to suit particular me~hods of operation. In the example shown in Figure 1 the catch member 9 has a shaped aperture 13 through which the bar 1 can extend to lock the locking means and member 9 together.
In Figures 1 and 2 the catch member 9 is L-shaped, in plan, with the aperture 13 in the short arm of the L. The longer arm 20 can be of any length so that the invention when sold as a kit and when the locking means is fixed in position the length required for the arm 20 of the catch member 9 can be measured and any excess 20' (dotted) cut off.
Alternative examples of the way in which such a kit can be installed are shown in Figures 5 and 6 and will be described hereafter.
In the example of the invention shown in Figures 3 and 4 the locking means and catch member 9 are generally the same as those shown in Figures 1 and 2. Similar parts thereof are referenced by the same numerals. In this ~ example the lock 15 has a circular, in cross section, latch bar 1 which, in use, engages in a circular hole 13 in the catch member 9. The catch member 9 is mounted at its end 21 via a pin 22 to a block~10. The block 10 can be fixed to a gate post, frame or wall so that arcuate movement of the catch member 9 moves the end of the short arm through the slot 7 and into position relative to the housing 2 so that the bar 1 extends through the hole 13. The pin 22 is ~;~Ei7~
fitted within a recess 23 in the block 10 and the top 24 of the pin 22 can be welded to the top of the member 9.
The catch member 9 and locking means can be mounted in a number of ways and examples are shown in Figures 5 and 6.
In Figure 5 the catch member 9 is fixed relative to a gate 33 by welds 25 to a vertical post 26 of a tube and wire gate. The locking means 27 being welded at 28 to a gate post 29 alongside which the post 26 is situated.
In Figure 6 the catch member 9 has f ixed relative thereto a connector member 30 the curved edge 31 of which is welded to a vertical post 26. The member 30 has a hole therethrough into which a pin 32 extends. The pins 32 may be a bolt the head of a nut of which is tack welded to the member 9. The pin 32 and member 9 being f ree to rotate relative to the hole in the member 300 This allows the member to be pivoted arcuately in the direction of arrow 34 for use, for example with a sliding door or gate.
In the example shown in Figures 3 and 4 the mounting ~ 10 includes a pivot pin 12 about which the arm 9 rotates to allow the engaging end 11 to enter the slot 5 of the housing 2. The end 11 having an aperture 13 in which the latch bar 1 can engage. It is to be appreciated that the arcuate movement of the locking arm 9 can be in a horizontal plane as shown or in a vertical plane or in association with sliding movement of the arm 9 in an elongate housing.
g ~Z~7~
In use the locking means and the catch 3 bar can be mounted on a set of gates, or on the side edge of one gate where it is to be closed against a post. Either the locking means or catch bar can be fitted to the post or gate. In the case of a set of pipe gates with netting covering the locking means or locking bar can be welded to the gate and/or post.
The present invention can be used in a variety of situations for example on the gates of a car park and the like. An advantage of the invention is that the ease with which the combination on either the cards and/or the latching means can be changed allows for frequent changes as required.
Thus by this invention there is provided a locking means for a closure which is inexpensive to manufacture and easy to use and which is of the type in which a locking combination thereof can be readily changed.
Particular examples of the invention have been described herein by way of example and it is envisaged that ~ improvements and modifications can take place without departing from the scope and spirit of the appended claims.
