DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a hardware component for connecting a swinging panel to an adjacent stationary component, said component comprising a first part mountable on one of the panel and the stationary component, a second part mountable on the other of the panel and the stationary component, and connecting means for connecting the first and second components.
BACKGROUND
Conventional gate and door hardware of this type, e.g. a latch or a hinge, is generally of good design and adequate for its intended purpose until the gate or door panel and the associated post or frame become misaligned, for example through ground movements or building settling. Such movements can occur seasonally. The result is misaligned panels that cannot be closed properly. In the case of a gate, damaged, broken or bent latch components may result.
The present invention is intended to ameliorate this problem.
SUMMARY
According to one aspect of the present invention there is provided hardware of the aforesaid type characterized in that the connecting means include adjustment means for adjusting the relative positions of the first and second components.
In one embodiment, the hardware is a latch for latching a swinging panel to an adjacent stationary component, in which: movement therealong, receiving the striker, striker in the receiver throat, and the track, such that a misaligned striker, on engaging the receiver throat will cam the receiver throat to a position in which the striker will seat in the receiver throat and be captured by the latching member.
The latch is thus self adjusting in that the striker will cam the receiver to a position where the striker may be fully seated in the receiver throat and captured by the latching member.
In another embodiment, the hardware is a hinge in which: with the pair of first knuckles, knuckles, and position between the first knuckles.
According to this embodiment of the invention, the misalignment is taken up on the hinge side of the gate by relative vertical movement of the two hinge components.
In another embodiment of the invention, the hardware component is a hinge in which; first knuckle having an internal threaded bore arranged coaxially with the hinge axis; knuckles of the first plate, knuckles, with the hinge axis, and internal pin supporting means; and into the second knuckle means and joining the hinge plates for relative rotation about the hinge axis, each hinge pin having the first knuckles, surface of the second knuckle means, and pin supporting means of the second knuckle means.
Both hinge pins must be adjusted to adjust this hinge. The internal pin supporting means are preferably ball bearings on which the ends of the pins are seated. This embodiment may be molded from a plastics material. The adjustment is this case is fixed, so that the gate does not "float" as it does with the resiliently supported hinge arrangement.
In a further embodiment of the invention, the hardware is a hinge in which; first knuckle having an internal, substantially cylindrical bearing surface arranged coaxially with the hinge axis, and knuckles of the first plate, the second knuckle being shorter than the spacing between the first knuckles, coaxially with the hinge axis, and an internally threaded section; and relative rotation about the hinge axis, the hinge pin having with the substantially cylindrical bearing surfaces of the respective knuckles, supporting surfaces of the first knuckle means, and means.
A conventional door hinge is designed with five knuckles. This always provides two bearing surfaces on the jamb plate knuckles to take the door load. This has been found to be desirable in order to prevent excessive wear. With an adjustable hinge, it is of importance to maintain this load distribution on the jamb plate. However, because the knuckles do not rest on one another, this prior art load distribution technique is not available. With the present embodiment, the load is transmitted to the jamb plate by the hinge pin. With two bearing surfaces on the pin,
