Abstract

A two-piece door has a first panel e hingeable at c to a door jamb and a second main panel d hinged to the first panel to swing in reverse direction, and the main section having rollers f with a connecting rod g attached between the rollers and a point spaced a distance, corresponding to the width of the first panel, from the hinges b the rollers being moveable on a U-sectioned overhead rail inside the doorway lintel. A spring h may be positioned at the hinged joint between the door sections for maximal extension at an intermediate position of the door opening, the spring tension thereafter urging the door to a fully opened position or, during closure, to the fully closed position. <IMAGE>

Description

SPECIFICATION Improvements in Doors For Large Garages This invention relates to improvements in doors for large garages or similar buildings.
Garage doors have been proposed in which either two doors of equal size are hinged at the side and open outwards, or alternatively a single door is pulled upwards from the outside and slides into position on runners beneath the garage ceiling. These arrangements are adequate for garages up to a width of about 13-14 feet (44.5m) but when the width is increased to facilitate accommodation of two cars, the doors become wider, heavier and more cumbersome.
Where there are two doors it is necessary to strengthen the door jambs and hinges to hold the doors upright and swinging them open requires a great deal of manual effort and where there is a single upward-swinging door it is also increasingly liable to bend out of shape and is then difficult to slide into the open position.
The object of the present invention is to provide doors for a wide double garage, which require minimal strengthening of the doorjambs and hinges and which may be opened without a great deal of manual effort. According to the present invention two-piece garage doors having the side section or guichet hinged at the door jamb and the main section hinged to the guichet in the reverse direction so as to swing inwards at one side when the door is pulled open from the outside. The weight of the main section is borne by a slider through a connecting rod attached between the slider and a point spaced at a distance corresponding to the guichet width along the upper edge of the main section. The slider, which may be a four-wheeled roller, is moveable along a rail on the inside of lintel.When the door is opened, the main section pivots about the connection rod and the roller moves along the rail in the direction of the door jamb. This arrangement facilitates the opening and closing of large garage doors, each of which may be about 8ft (2.5m) wide, requires little or no additional strengthening of door jamb and hinges, and also allows partial opening of the door so that a person may pass through.
A preferred embodiment of the invention is described in detail with reference to the accompanying drawings. In Fig. 1 the garage doors are shown in the closed position with hinges (c) attached obversely between door jamb and guichet (e) and hinges (b) attached in the reverse direction, with the hinge pin outside the door, between the guichet and the main section (d). Positioning the rear face of the guichet flush with the rear face of the door jamb facilitates the hinging of the guichet. The weight of the main section is borne by a slider which in this embodiment is a trolley-like roller (f) through a connecting rod (g) which is attached between the roller and a point along the upper edge of the main section at a distance from the joint corresponding to the width of the guichet.The connecting rod (g) attaches behind the upper edge of the door and the attachment provides that the door may pivot in a plane perpendicular to the rod, the rod being substantially vertical. The slider is moveable along an overhead rail positioned inside lintel as shown. In this preferred embodiment, the rail has an inverse U section with channel section arms. A spring (h) is positioned across the hinged joint between the door sections. The spring extends for an equal distance either side of the joint and it may be located immediately above the upper edge of the door where there is sufficient space behind the lintel or an equivalent recess in the lintel, as shown, or alternatively neighbouring a recess in the upper edge of the door itself.The part of the main door section beyond the connecting rod or pivot point may be an additional one or more inches longer at its lower edge compared to the remainder of the door in order that when the door is closed it shall abut the front of the step formed by the edge of the garage floor, and the doors will always be brought level for locking. Fig. 2 shows one garage door in the half-open and open positions. When the door handle (a) is pulled outwards, the hinges (b) allow the main door section (d) to swing outwards with respect to the guichet (e) while the hinges (c) between the door jamb and guichet allow the guichet to swing inwards. At the same time the main section of the door pivots about its connection to the rod (g) and the rollers (f) bearing the weight of the main door section, move along the rail in the direction shown towards the door jamb.When the door is half open, the spring (h) over the joint is extended maximally and thereafter during opening the tension of the spring acts to decrease the length of the spring over the joint and pull the door fully open. Conversely when closing the door, once the door is half closed and the spring maximally extended, the tension acts to pull the door fully closed. Thus the spring moves over the joint during opening and closing the garage door.
When the door is fully open there is still a gap, about six inches wide, between the guichet and the side wall of the garage so that implements may be stored hanging on or leaning against the wall.
Claims
1. Two-piece garage door with a guichet hingable at the door jamb and the main section hinged to the guichet in the reverse direction to swing inwards at one side when the door is pulled open from the outside, the main section having a slider with a connecting rod attached between the slider and a point spaced a distance corresponding to the guichet width along the upper edge of the main section, the slider being moveable along an overhead rail inside the lintel.
2. Two-piece garage door according to Claim 1 wherein a spring is positioned at the top of the hinged joint between the door sections whereby the spring is progressively extended as the door opens until the door is half open, at which point

A spring (h) is positioned across the hinged joint between the door sections. The spring extends for an equal distance either side of the joint and it may be located immediately above the upper edge of the door where there is sufficient space behind the lintel or an equivalent recess in the lintel, as shown, or alternatively neighbouring a recess in the upper edge of the door itself.The part of the main door section beyond the connecting rod or pivot point may be an additional one or more inches longer at its lower edge compared to the remainder of the door in order that when the door is closed it shall abut the front of the step formed by the edge of the garage floor, and the doors will always be brought level for locking. Fig. 2 shows one garage door in the half-open and open positions.

Claims
1. Two-piece garage door with a guichet hingable at the door jamb and the main section hinged to the guichet in the reverse direction to swing inwards at one side when the door is pulled open from the outside, the main section having a slider with a connecting rod attached between the slider and a point spaced a distance corresponding to the guichet width along the upper edge of the main section, the slider being moveable along an overhead rail inside the lintel.
2. Two-piece garage door according to Claim 1 wherein a spring is positioned at the top of the hinged joint between the door sections whereby the spring is progressively extended as the door opens until the door is half open, at which point the spring is maximally extended and thereafter during opening the tension of the spring acts to decrease the length of the spring and pull the door fully open. Conversely when closing the door, once the door is half closed the spring tension acts to pull the door fully closed.
