A ground surface access assembly with lock-open cover
A ground surface access assembly (10, Figure 6) comprising a frame (12, Figure 6) and a cover (14a, Figure 6) that sits within the frame (12, Figure 6). There are 2 hinge means located partly on an inner wall 18 of the frame (12, Figure 6) and partly on a side face (30, Figure 10) of the cover (14, Figure 6) each formed by pivot members 16a,b loosely located in an open recess (20a, Figure 6) defined by inner sidewalls (26a, Figure 4). The two hinge means together allow the cover (14, Figure 6) to pivot relative to the frame (12, Figure 6) about an axis (A-A’, Figure 3) that is not rigidly fixed but tilts in a horizontal and vertical plane. During the last stages of opening of the cover (14, Figure 6) a rear edge portion (58, Figure 10) of the cover (14, Figure 6) is automatically securely located in an open position as the rear edge portion (58, Figure 10) is guided by a guide ramp 48 into an engagement slot 50, both being located on an adjacent inner wall 18 of the frame (12, Figure 6).
