DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hinges of the present invention are preferably made by machining the first and second components from an extruded member. Alternatively, the overall hinge can be moulded or otherwise made. The hinge pin preferably is turned or moulded or press formed.
Suitable materials include metals such as steel, brass, aluminium and the like. For some uses, extruded aluminium members may be machined to provide the first and second component. Likewise the hinge pin although, if desired the hinge pin can be of a dissimilar material. Moreover, if desired, each of the first and second components can be of a different material.
A routed cavity 16, preferably at about 45° is shown in FIGS. 13 and 14. It is provided to receive, for a first component 1, most of the leaf region thereof. Likewise a 45° or thereabouts cavity in the door 2 to receive the leaf of the second component 3. A shown a hinge pin can hold the aligned and interposing sleeves of components 1 and 3 in register to allow pivoting one relative to the other.
Shown in FIG. 13 are the screws 4 of the first component 1 and the screws 5 of the second component 3.
Preferably the view is not as in FIGS. 9 and 10 but rather has one of the leafs rotated by 180° from that condition so that it is essentially only the revealed regions of the hinge pin 6 and the aligned sleeves that can be seen. See FIG. 13 in this respect.
Shown in FIG. 1 are sleeves 7 and 8, the leaf 9 and the screw receiving passageways 10.
Likewise for the component 3, there are sleeves 11 and 12, the leaf 13 and screw receiving passageways 14. The head 15 of the hinge pin 6 can be seen as if were part of the sleeve sequence.
For heavy applications, or as an alternative method of fixing, it is possible to insert an insert nut in the bottom of the routered cavity for the purpose of using machine screws for fixing.
If desired a hex head screw can be used for fixing, making it easier to engage the head of the screw in the countersunk portion of the leaf, as a standard Phillips or Pozi Drive screw head of the size required would be difficult to get the degree of fixing without wearing or stripping the screw head.
In manufacture from certain materials, there can be the insertion of a nylon or plastic sleeve inside the sleeve for the hinge pin to reduce friction on the hinge pin, and the insertion of a nylon or plastic load bearing material between the sleeve (“knuckles”) to act as a washer. This is desirable in aluminium hinges.
A suitable fitting sequence is to jig machine router appropriate cavities in the jamb joinery and the door and/or window. Thereafter the components 1 and 3 can each be fitted and prior to hinge pinning of the components one to the other.
