Abstract
An adjustable hinge has two plates connected by a series of knuckles, at least two on one plate and one on the other. The spacing between adjacent knuckles on one plate is greater than the length of the intervening knuckle on the other plate so that the knuckle may be moved along the hinge pin joining the knuckles. To effect this movement, the adjustable knuckle and the hinge pin are threaded. To provide adequate strength to the hinge, the pin and the non-adjustable hinge plate knuckles have two sets of axially facing support surfaces so as to distribute the hinge load over a sufficient area. Lateral loads on the threading may be limited through the use of cylindrical pin and knuckle sections.
Description
HINGE
The present invention relates to hinges and more particularly to adjustable hinges.
It is desirable to mount most hinges with some precision so that the coupled components, for example, a door in a door jamb will open and close properly. With conventional hinges, there is no provision made for door adjustment. Consequently, where subsequent movements of the structure occurs, as in building settling, the hinges must be repositioned or the top or the bottom of the door must be cut or planed accordingly.
To address these problems, there have been various proposals for adjustable hinges. None of these has been accepted because they have been either complex or insufficiently robust for long term use.
The present invention is concerned with the provision of an improved adjustable hinge structure.
According to a broad aspect of the present invention there is provided a hinge for connecting a swinging panel to an adjacent stationary component. The hinge comprises a first hinge plate mountable on the stationary component;
a second hinge plate mountable on the panel; first knuckle means on the first hinge plate and including at least two aligned first knuckles spaced apart along a hinge axis, the first knuckles having internal, substantially cylindrical bearing surfaces of the same diameter and arranged coaxially with tree hinge axis, and respective pin supporting surfaces facing in opposite axial directions;
second knuckle means on the second hinge plate and including at least one second knuckle aligned with and positioned between the first knuckles of the first plate, the second knuckle being shorter than the spacing between the first knuckles, two axially spaced apart internal, _2_ substantially cylindrical bearing surfaces arranged coaxially with the hinge axis, and an internally threaded section between said two substantially cylindrical bearing surfaces; a hinge pin extending through the knuckles and joining the hinge plates for relative rotation about the hinge axis, the hinge pin having a first substantially cylindrical bearing section engaged rotatably with the substantially cylindrical bearing surface of one of the first knuckles, a second substantially cylindrical bearing surface positioned within the other of the first knuckles, a third substantially cylindrical bearing surface engaged rotatably with one of said two bearing surfaces of the second knuckle, an axially facing knuckle engaging surface engaging the pin supporting surface of said one of the first knuckles, and a threaded section threaded into the threaded section of the second knuckle means and a bushing secured in said other of the first knuckles the bushing having a closed end engaging an end of the pin and a substantially cylindrical bearing surface engaged rotatably with the second substantially cylindrical bearing surface of the pin.
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 dis~.ribution on the jamb plate.
However, because the door plate knuckle or knuckles do not rest on jamb plate knuckles, this prior art load distribution technique is not available. With the present invention, the load is transmitted to the jamb plate by the hinge pin. With two bearing surfaces on the pin, and corresponding bearing surfaces on the jamb plate, an adequate distribution of this load is provided. Left and right hand hinges will be required to accommodate left and right hand doors.

In preferred embodiments, a low friction washer, e.g. of nylon or some other low friction material, is placed below the pin head and a similar low friction bushing caps the bottom end of the pin. The washer and bushing act as the bearing surfaces, and substantially outlast a metal to metal contact.
Another area of weakness in the prior art hinges is the use of a threaded pin as a bearing surface for guiding rotation of the hinge knuckles.
In preferred embodiments of the present hinge, the second knuckle means has an internal, substantially cylindrical bearing surface engaging the hinge pin.
Thus, both of the plates are supported on the pin by smooth, cylindrical mating sections of the knuckles and the pin. This provides the required lateral support to the door plate without stressing the threads and causing their premature failure.
In preferred embodiments, the threads are "locked" by a rotation-resisting element, for example a nylon insert in the threaded part of the pin.
This ensures that none of the normal rotation of the hinge takes place along the threaded section of the pin and the mating knuckle.
In the accompanying drawings, which illustrate an exemplary embodiment of the present invention:
Figure 1 is an elevation of a hinge according to the present invention;
Figure 2 is an elevation like Figure 1 with the knuckles shown in cross section;
Figure 3 is an elevation of the hinge pin, partially broken away to show the insert;
Figure 4 is a top view of the hinge; and - 211353' Figure 5 is a cross section of a bushing for the lower knuckle.
Referring to the accompanying drawings, there is illustrated a hinge 10 that includes a jamb plate 12 and a door plate 14. These are coupled to rotate on a hinge axis 16. Each plate is provided with conventional screw holes 18 that are used for mounting the plates on a jamb and a door respectively.
The jamb plate 12 is equipped with upper and lower knuckles 20 and 22 respectively. These are spaced apart along the hinge axis 16.
Interposed between the knuckles 20 and 22 is a knuckle 24 mounted on the door plate 14. The knuckle 24 is shorter in length than the space between the knuckles 20 and 22 so that spaces 26 and 28 are provided above and below the knuckle 24 providing room for its adjustment up and down.
The three knuckles are joined by a hinge pin 30 that extends through the three knuckles. The pin has an enlarged head 32 at the upper end. The upper end of the pin has a socket 34 for engagement with a rotating tool, in this case an alien key.
Immediately below the pin head 32 is a low friction nylon washer 36. This engages between the support surface 38 under the pin head and the support surface 40 at the top end of the upper knuckle 20.
The pin 30 has an upper cylindrical bearing section 42 that fits rotatably into the inner cylindrical surface 44 of the upper knuckle 20 and the inner cylindrical surface 46 of the centre knuckle 24. Below the cylindrical bearing section 42, the pin has a threaded section 48 that engages a threaded section 50 adjacent the bottom end of the centre knuckle 24. The threaded section 48 of the pin is engaged with the threaded section 50 of the knuckle 211353°
to provide for travel of the knuckle up and down on the pin as the pin is rotated in the knuckle. The arrangement is such that any adjustment will not result in thread exposure. A transverse bore 52 extends through the threaded section of the pin 30 and holds a nylon insert 54 projecting into the threads on opposite sides of the pin. This insert is engaged by the threads on the knuckle 24 and deformed by them to resist relative rotation of the pin in the knuckle.
At the same time, the resistance to rotation is not so high as to prevent the rotation of the pin with a tool engaging the socket 34 in the head.
Below the threaded section 48, pin 30 has a step 56 leading to a lower cylindrical bearing section 58. This lower cylindrical bearing section engages rotatably in a bushing 60 fitted in and secured to the lower knuckle 22. The bushing 60 (Figure 5) is made from a low friction nylon and has an internal cylindrical bearing surface 62 that engages the lower cylindrical section of the pin. It also has a head 64 closing the end of the bushing. An inner end face 66 of the head supports the bottom end of the pin 30 as an axially facing support surface.
In use of this hinge, the bushing 60 and the washer 36 act as two separate support surfaces for the hinge pin 30. The load on the pin is thus transmitted to the support surfaces 40 and 66. The load from the door plate is transmitted to the hinge pin through the threaded sections of the door plate knuckle and the pin. Because of the engagement of the cylindrical pin surface with the cylindrical inner surface of the centre knuckle, the load transmitted through the threads is primarily axial and the threads do not need to resist the radial forces and bending moments applied to the pin. When the position of the door plate 14 must be adjusted with respect to the jamb plate 12, an - 21135'7 appropriate tool is engaged in the socket 34 in the pin head and the pin is rotated with respect to the door plate. This will either raise or lower the door plate on the hinge pin, providing the necessary adjustment.
In the illustrated embodiment, the bushing 60 is secured in the lower knuckle 24 by being pressed in place and fastened with a commercial adhesive providing a sheer strength in excess of 2500 psi.
While one embodiment of the present invention has been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. For example, a hinge with more than three knuckles could be constructed.
The particular configuration of the thread may be selected according to the needs of a particular hinge design. It may be desirable in some embodiments to use a power screw thread profile, for example square, Acme or buttress in order to provide added strength.
The invention is therefore not to be considered limited to the illustrated and described embodiments, but solely by the scope of the appended claims.
