Abstract

A series of locks are described for preventing child access to cupboards and the like. The locks are preferably concealed and are opened by a proximity of a remote actuator, for example a magnet actuating a reed switch. An override or master switch may also be used to open all locks, for example, for a set period while emptying a dishwasher.

Claims

1. :

A locking system for preventing child access to a cabinet, cupboard or drawer comprising;

a power supply configured to energise a plurality of locking systems,

a locking mechanism actuatable to unlock said cabinet, cupboard or drawer when energised,

an at least partially concealed switch electrically coupled between said power supply and said locking mechanism, and

a remote actuator held by a user whereby bringing said actuator in proximity to said switch causes said switch to close thereby energising said locking mechanism from said power supply and unlocking said cabinet cupboard or drawer.

2. :

The system as claimed in claim 1 comprising a single power supply and a plurality of locking mechanisms and switch actuator combinations.

3. :

The system as claimed in claim 1 wherein said switch is a reed switch and said actuator is a magnet.

4. :

The system as claimed in claim 1 wherein said switch is a radio receiver and said actuator is a radio transmitter or interrogable device.

5. :

The system as claimed in claim 1 wherein said locking system returns to a locked position when said actuator is non proximate said switch.

6. :

The A system as claimed in claim 1 further comprising an override connection which may be connected to bypass said switch and thereby connect said locking mechanism directly to said power supply.

7. :

The A system as claimed in claim 6 further comprising an override switch which when actuated connects said override connection to said power supply thereby energising each locking mechanism.

8. :

The A system as claimed in claim 7 wherein said override switch connects said override connection to said power supply for a predetermined period.

9. :

The A system as claimed in claim 8 wherein locking mechanism is a solenoid which activates a latch bolt which engages a striker within a stationary portion of said cabinet cupboard or drawer.

10. :
