Description

Hinge

Background

This invention relates to a hinge used on timber doors, framed glass doors and bonded glass doors.

Typically, there are various types of hinge used on single action timber and framed glass doors. One type that exists is the offset pivot hinge. This hinge is fitted to the top and bottom of the door leaf and allows the door to sit upon a floor mounted spring that is recessed into the floor.

Existing hinges are specifically designed to work on either a timber door or a framed glass door.

These existing hinges are also fixed through the rear face of the door leaf, requiring them to be bulky items that deface the visible surface of the door leaf. The fixings for these are then either visible or covered with a sticker or cap.

When used on a framed glass door the metal frame of the door requires extra components to create a strong enough fixing for the hinge.

When used on a bonded glass door the hinge requires holes or edge machining in the glass to allow for the hinge fixing. This is expensive and can cause tolerance issues if the holes or edge machining are not accurate. Having holes or edge machining in the glass also creates stress forces in the glass corners that can cause the glass to fail and break, either creating cracks or to completely shatter the entire glass pane.

Modern doors need to meet high acoustic performance requirements. In order to greatly improve the acoustic performance of doors it is typical to use a drop seal assembly within the bottom of the door. The fixing location of existing hinges does not allow space for a drop seal assembly within the bottom of the door.

Solution

The hinge invention overcomes these problems by fixing into two edges around the corners of the door leaf. The top hinge is fixed into the top and side edges of the door. The bottom hinge is fixed into the bottom and side edges of the door.

These fixings are then inherently concealed when the door is closed. The do not require any cover caps.

The fixings into the edge of the leaf are identical for timber doors, framed glass doors, and bonded glass doors.

The hinge is designed to have a very minimal machining to the edge of the door. The edge fixing of this invention means that the glass panes of glass doors do not require drilled holes or edge machining. This reduces the cost and environmental impact of the extra machining on the glass. It also means the glass does not have weak points that can crack or cause the glass to fail and shatter.

The invention is fixed on two planes, which makes it strong enough to enable the minimal machining to the edge of the door.

The strong two plane fixing method of the invention allows space for the use of a drop seal assembly for improved acoustic performance. The design of the invention is such that it does not inhibit the action or the trigger method of the drop seal assembly.

Detailed description

The hinge is a multi-part assembly comprising of a bottom door component, top door component, and a doorframe component. These are typically manufactured in aluminium or steel by either CNC or casting processes. The bottom door component has a hole feature that allows it to be used with a floor pivot plate or floor spring. The top door component has a feature that allows it to mate with the doorframe component. The doorframe component has a rod feature that projects into the mating feature on the top door component, allowing the door to swing open and closed.

Figure 1 shows the bottom door component 1, the top door component 2, and the doorframe component 3. The bottom door component 1 has a horizontal fixing surface 5 and a vertical fixing surface 6 which are linked to the pivot block 7 that houses the hole feature that allows it to be used with a floor pivot plate or floor spring. The horizontal fixing surface 5 has screw fixing holes 8. The vertical fixing surface 6 has screw fixing holes 9. The top door component 2 has a horizontal fixing surface 10 and a vertical fixing surface 11 which are linked to the pivot block 12 that houses the hole feature that allows it to be mated with the doorframe component 3. The horizontal fixing surface 10 has screw fixing holes 13. The vertical fixing surface 11 has screw fixing holes 14. The doorframe component 3 has a horizontal fixing surface 15 that is linked to the pivot block 16 that houses the pivot rod 4, which allows it to be mated to the top door component 2. The horizontal fixing surface 15 has screw fixing holes 17.

Figure 2 shows a timber door 18 fitted with the bottom door component 1 and the top door component 2. These are screw fixed to the timber door 18. The doorframe component 3 is screw fixed to a doorframe 19. The door assembly comprising timber door 18, bottom door component 1, and top door component 2 seats onto the floor spring 20.

Figure 3 shows a bonded glass door 21 fitted with the bottom door component 1 and the top door component 2. These are screw fixed to the bonded glass door 21. The doorframe component 3 is screw fixed to a doorframe 19.

The door assembly comprising bonded glass door 21, bottom door component 1, and top door component 2 seats onto the floor spring 20.

Figure 4 shows the timber door 18 with the machining to accept the hinge components. Side machining 22 mates with the vertical fixing surface 11 of the top door component 2. Top machining 23 mates with the horizontal fixing surface 10 of the top door component 2. Side machining 24 and side machining 25 pass to the main surface of the timber door 18, these are required to allow for the link between the horizontal fixing surface 10, vertical fixing surface 11, and the pivot block 12 of the top door component 2. These features are then mirrored at the bottom of the door as highlighted by the bottom machining 26 to suit bottom door component 1.

Figure 5 shows the bonded glass door 21 with the machining to accept the hinge components. Side machining 22 mates with the vertical fixing surface 11 of the top door component 2. Top machining 23 mates with the horizontal fixing surface 10 of the top door component 2. Side machining 24 and side machining 25 pass to the main surface of the bonded glass door 21, these are required to allow for the link between the horizontal fixing surface 10, vertical fixing surface 11, and the pivot block 12 of the top door component 2. These features are then mirrored at the bottom of the door as highlighted by the bottom machining 26 to suit bottom door component 1. Side edge machining 24 and top edge machining 25 do not interfere with the glass pane 27.

Figure 6 shows the typical screw fixing of the bottom component 1 to the timber door 18. The bottom component 1 is positioned on the door such that vertical fixing surface 6 fits into side machining 30, and horizontal fixing surface 5 fits into bottom machining 31. Once the bottom component 1 is placed into position within the machining in the door it is fixed on the side of the door using screw fixings 28, and through the bottom of the door using screw fixings 29. This view also highlights the hole feature 32 that allows the bottom component 1 to be used with a floor pivot plate or floor spring.

Figure 7 shows the typical assembly of a timber door 18 fitted with the top component 2 and the bottom component 1 with a drop seal assembly 34. The bottom component 1 is shown with a horizontal fixing surface 33 that is designed to allow for the drop seal assembly 34 to bypass the majority of the bottom component 1. The bottom component 1 is shown with a vertical fixing surface 35 that has a drop seal trigger hole 36 that allows for the drop seal trigger button 37 to activate when the door is closed.
