Abstract

An adjustable hinge system comprising of a hinged bracket 1 having a knurled surface 8, a retaining plate 2 having a knurled surface 9 and folded edges 10, locating screw 5 and fixing screws 6 and 7. A door 3 can thereby be adjusted in position and temporarily held by the knurled surfaces on tightening screw 5 before permanent fixing is established by tightening the screws 6. <IMAGE>

Description

ADJUSTABLE HINGE SYSTEM Hinge systems have in the past provided a means to hang a door on a frame, but suffer from the disadvantage that no adjustment of that hinge position is possible once it is fixed. This is a severe shortcoming when initially fixing a door and subsequent adjustment.

In order to overcome this disadvantage, the invention provides a hinge system that allows adjustment of the door with respect to the frame. either during initial installation, or at any time in the future.

According to the invention, therefore, an adjustable hinge system comprises of a hinged bracket, a retaining plate, locating screw and fixing screws, the locating plate being such as to allow the hinged bracket to be moved with respect to such retaining plate.

The system may be manufactured from all standard hinge materials, comprising. mild steel, stainless steel, brass, alloys, plastic.

The system allows for adjustment of all types of hinge system, comprising, butt hinge, backflap hinge, concealed hinge, liftoff hinge, cabinet hinge, caravan hinge, spring hinge, double knuckle hinge, rising hinge.

Although the invention has been defined from one aspect hereinbefore, it is to be understood that it includes any integer or step, or combination of integers or steps, which is or are described herein and/or shown in the drawing, and is or are novel and inventive.

How the invention may be carried into effect it hereinafter particularly described with reference to the accompanying drawing, in which:- Fig. 1 shows the system for attachment to a door and frame (the other adjustable hinges are not shown).

A frame 4 is prepared to receive the retaining plate 2 such that it is recessed adequately to make the retaining plate 23 top surface flush with the frame 4. The retaining plate 2 is 'fixed to the frame 4 by screw 5, screw 5 being tightened such that retaining plate 2 begins to deform. Prepare holes in the frame 4 ready to accept screws 6.

A door 3 is prepared to receive the hinged bracket 1 such that it is recessed adequately to make the hinged bracket 1 top surface flush with the door 3 and fixed by screws 7.

Slide hinged bracket 1 fixed to door 3 between frame 4 and slot created by 450 folded edges 10 on retaining Plate 2 and loosely fix screws 6. Adjust height of door 3 to that required and tighten screw 5, the interaction of Knurled surface 8 and Knurled surface 9 providing locking between hinged bracket 1 and retaining plate 2. Test for desired operation. If correct, tighten screws 6. If incorrect, loosen screw 5, adjust height and repeat test sequence.

Claims

1. A hinge system particularly for hanging door to a frame, allowing adjustment.

2. A system according to Claim 1 including a retaining plate having 450 folded lugs and a Knurled surface, to receive and interact with the hinged bracket providing locking and adjustment.

3. A system according to claim 1, including a hinged bracket having Knurled surface that interacts with the retaining plate, providing adjustment and locking.

4. A system according to Claim 1, with no restrictions on Physical dimensions.

5. An adjustable hinge system substantially as described hereinbefore with reference to the accompanying drawing.

6. A system which can be used on hinge designs to include butt hinge, backflap hinge, concealed hinge, lift-off hinge, cabinet hinge, caravan hinge, spring hinge, double-knuckle hinge and rising hinge.

7. A system that can be manufactured from mild steel, stainless steel, brass, alloys, plastic and all common hinge materials not mentioned herein.

8. A system according to claim 1, including screws providing the fixing of the hinge bracket and retaining plate.

9. Any other integer or step or combination of integers or steps, described hereinbefore and or shown in the drawings which is novel and inventive whether falling within or without the terms of the foregoing claims.
