ELECTRONIC WARNING SYSTEM FOR A BUCKLE USED WITH A HARNESS

Abstract

The invention is a buckle having a means for providing an alert upon the use of the buckle comprising a buckle body, at least one buckle connector that releasably connects to the buckle body, a buckle mechanism within the buckle body that latches with respect to the buckle body, the buckle mechanism also being operable to release the buckle connector, a signal module attached with respect to the buckle body produces an alert signal, switch means on the signal module that, when operated, causes the signal module to produce an alert signal, and an actuator that is moved by either the buckle mechanism or the buckle connector to operate the switch means when the buckle connector connects or disconnects to the buckle body. The invention provides a means if indicating when the buckle is properly connected and also when the buckle is being disconnected. This will provide an alarm when the buckle is being inadvertently released.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

The embodiment is illustrated in the accompanying drawings in which;

FIG. 1 shows a perspective view of a buckle body and a pair of buckle connectors,

FIG. 2 shows schematically the operation of the resilient member between the latching bar and the switch of the signal module,

FIGS. 3 to 5 show alternative connection means to secure the signal module in respect of the buckle body, and

FIGS. 6 and 7 show an alternative actuator.

Claims

1. A buckle providing an alert upon use of the buckle comprising, a buckle body,at least one buckle connector that releasably connects to the buckle body,a buckle mechanism within the buckle body that latches to the buckle connector to hold it with respect to the buckle body, the buckle mechanism also being operable to release the buckle connector,a signal module attached with respect to the buckle body that produces an alert signal,a switch on the signal module that, when operated, causes the signal module to produce the alert signal, andan actuator that is moved by either the buckle mechanism or the buckle connector to operate the switch when the buckle connector connects or disconnects to the buckle body.

2. A buckle according to claim 1 wherein the alert signal comprises an audible signal.

3. A buckle according to claim 2 wherein the alert signal comprises a visual signal.

4. A buckle according to claim 1 wherein the alert signal is a combination of an audible and visual signal.

5. A buckle according to claim 1 further comprising a transmitter that transmits an alert signal to receiver at a remote location.

6. A buckle according to claim 5 wherein the alert signal comprises either an audible signal, a visual signal or both an audible and visual signal.

7. A buckle according to claim 1 wherein the signal module attaches to the exterior surface of the buckle body.

8. A buckle according to claim 7 wherein the signal module comprises a housing and a circuit board located within the housing, the circuit board including the switch means, power source, speaker and circuitry to produce an audible signal upon operation of the switch means.

9. A buckle according to claim 8 wherein the actuator comprises a resilient member that locates between the switch means and the buckle mechanism.

10. A buckle according to claim 9 wherein the portion of the buckle mechanism that the actuator bears against is a latching bar.

11. A buckle according to claim 10 wherein the actuator is compressed when the latching bar is in a first position to thereby apply constant pressure against the switch means and un-compressed when the latching bar is in a second position so that the switching means is not operated.

12. A buckle according to any one of claims 9 to 11 wherein the actuator is a resilient polymeric pin.

13. A buckle according to any one of claims 9 to 11 wherein the actuator is a combination of a metal pin and a resilient polymeric portion.

14. A buckle according to claim 13 wherein the polymeric portion comprises a boot that engages one end of the metal pin.
