Embodiment Construction

[0088]With reference to FIG. 1a, 1b, 2 and 4, 5 and 6 there is shown a coupler as generally indicated by 1. Coupler 1 includes a body portion 2 to which is attached a fixed jaw 3. The jaw 3 is fixed in the sense that it does not move with respect to the body portion 2. It will be appreciated that fixed jaw 3 may take a number of forms without departing from the scope of the present invention. For example, fixed jaw 3 may be formed integrally with the body portion of coupler 2, or it may be attached to the body portion 2 by way of bolts or other suitable fasteners.

[0089]Fixed jaw 3 includes a ‘U’ shaped opening 3a facing in an outward direction substantially parallel to the length of the body portion. The ‘U’ shaped opening is configured to receive the circular cross section of a first attachment pin 12a (shown in FIG. 2) of an implement (shown in FIGS. 4, 5 and 6) the first pin 12a extends across the width of the fixed jaw 3 so as to be substantially transverse to the length of body...

Abstract

A coupler for attaching an implement to a machine, the coupler including a body portion, a first jaw configured to engage a first attachment portion associated with the implement; a moveable jaw configured to engage a second attachment portion associated with the implement; and a first sensor located on the body portion configured to detect the presence of the implement adjacent to the body portion and to indicate one of a safe position in which the implement is securely held by the coupler and an unsafe position in which the implement is not securely held by the coupler.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of parent International Patent Application No. PCT / NZ2014 / 000221, filed on Oct. 22, 2014. The entire disclosure of the prior application is hereby incorporated by reference in its entirety.TECHNICAL FIELD[0002]The present invention relates to improvements in and relating to couplers, in particular to couplers for attaching an implement to a machine.BACKGROUND ART[0003]Couplers are commonly used for releasably attaching various implements to a machine. An example of such a machine is an excavator. The couplers used by excavators commonly include at least one, or often two jaws. The jaw(s) each engage a pin on an implement to secure the implement to the coupler. The couplers are often remotely operable to release and engage an implement. The main reason for this is for ease of use. However, it may also be due to the fact that the implement to be attached is often large and / or heavy and is therefore impossib...
