2 Sheets-Sheet 2 ATTORNEY HINGE The present invention relates to an improvement in hinges having two hinge plates which are relatively pivotable about a pivot, and the invention is particularly intended for hinges of the type used for windows and doors without its being restricted to such hinges, since, as further explained hereinbelow, the hinge may also be used in other fields.

A large number of hinges for doors and windows are known, none of the known hinges being suitable for use in modern, rationalized production of doors and windows, however. One of the present requirements is that the door panels must be produced with ready milled cutouts for hinge plates, and the hinge plates must be of such type that the door panels may be hinged to the right or to the left of the door merely by turning the door around, the hinges being symmetrically positioned on the door panel. To achieve this, the hinges must be provided with loose hinge pins and, since these are relatively small, they are easily lost on a building site with the result that doors may stand unhinged for long periods of time, until new hinge pins have been provided.

The known hinges which permit symmetrical manufacture of door panels also have a hinge curl, however, which projects from the edge of the door panel and causes difficulties when storing door panels since they must be stored, for example stacked, with great care so that a hinge curl projecting from a door panel does not damage adjacent door panels in the stack.

The object of the present invention is primarily to provide an improvement in hinges so as to avoid the said disadvantages (loose hinge pins and damage to door panels in a stack), and this is achieved in that at least one side of the hinge comprises two plate members permanently hinged together where one of the plate members fits into a second hinge member com prising the other side of the hinge, which is permanently secured, for example, to a door panel. The said second member is provided with a guide for the one hinged plate member, and the two members of the hinge plate may be interlocked by means of a suitable snap-mechanism.

The invention thus relates to an improvement in a hinge having two first and second hinge plates where at least the first of the hinge plates is divided into two members, one member being intended, together with a door panel, to form a pocket for insertion and mounting of the second member of the hinge'and is substantially characterized in that the first said member of the hinge has plane surfaces at right angles one to the other, adapted for mounting in a cutout in the door panel in alignment with the side surfaces thereof.

A further feature of the invention resides in forming both hinge plates as a fitting and having a member which is adapted thereto.

A further feature of the invention is that the fitting is provided with a stop, locking lug or the like for locking of the second member of the hinge when this is inserted into the fitting.

In a preferred embodiment example, the fitting is provided with a slot and the second member of the hinge plate is provided with a tongue which fits into said slot and, furthermore, one'side of the fitting may be formed as a resilient lip having a stop or locking lug, and the fitting is preferably formed with plane surfaces at right angles one to the other so that the fitting may be mounted on a window sash or door panel in alignment with the side surfaces of the sash or door.

In order that the invention may be more readily understood it is further described in the following with references to the drawings where:

FIG. I shows a fitting seen from the side,

FIG. 2 shows a section through the fitting on FIG. I with the fitting mounted on to a door panel,

F IG. 3 shows the second member of the hinge,

FIG. 4 shows a second embodiment form of a hinge member and FIGS. 5 and 6 show how a door panel is set in place in a door frame.

A hinge effected in accordance with the invention shall have a fitting I with a central resilient lip 2 and screw holes 3 for mounting of the fitting in a milled cutout in, for example, a door panel 4 (FIG. 2). The fitting 1 fits the cutout 5 in the door panel 4 in such a manner that the door panel has plane side surfaces and edges 6. This substantially simplifies storage since finished door panels may be stacked without it being necessary to take into consideration the risk of damage to adjacent door panels in the stack from projecting hinge members.

The second member of the hinge (FIG. 3) has a curl 7 for permanent hinging of the hinge plate 8 (FIGS. 4 and 5) to the hinge plate member 9 which fits into the fitting I on FIG. I and is locked to this in the embodiment example illustrated by means of a slot II) which cooperates with a locking lug II on the underside of the resilient lip 2. The hinge member 9 is inserted into the fitting I, 2 as indicated by arrow 12 on FIG. 2, when the members which are to be interhinged are mounted together. On FIG. 4 the hinge is provided with two

hinge plates

8 and 9, for cooperation with respective fittings effected as illustrated on FIGS. I and 2. This offers the advantage that the hinge, when used on furniture for example, may be readily replaced by an unskilled person, and it is thus possible in a simple manner to fit the furniture hinge to furniture already in existence. If, for example, existing furniture sections are provided with hinges and other fittings made of bronze, it is hardly suitable to have, for example, nickel hinges on new articles of furniture, even though these otherwise suit the furniture. With the fitting illustrated on FIG. I mounted on furniture and on doors, and with the movable parts of the hinge effected as illustrated on FIG. 4, it is therefore simple to replace the hinges without any further work on the article of furniture. The movable parts of the hinge may be readily released from the fittings I by using a suitable tool through a slot 13 and lifting the tongue or lip 2 so that the lug II is disengaged from the slot III). The

hinge plates

8 and 9 may then be readily withdrawn from the fittings I.

Hinges in accordance with the invention are, however, of particular importance in connection with hinging of door panels as explained hereinabove, and one hinge plate, designated by 3 on FIGS. 5 and 6, may then be effected in manner known per se and attached to a suitable extent in a door frame 14 or a part which is to be subsequently assembled as door frame. The member 9 is permanently hinged to the hinge plate 8, and mounting of the door panel 4 with the fitting I recessed in its edge surface is carried out by lifting the door panel with fitting 1 to the correct height in relation to the fitting member 9, as illustrated on FIG. 5, and, when the hinge member 9 and the fitting member 1 are brought together, as illustrated on FIG. 6, both at the upper and lower part of the door, the door is then hinged without use of further separate parts or tools. The hinging is so simple to carry out that risk of damage to pre-painted door panels and frames is much less than when previously known hinge types are used, and a further advantage in assembly of frame and door panel, on horizontal movement of the door panel, is that the sharp corners of the door panel will not be in a position to make marks and dents in door frames and mouldings around the door opening, this last being easily done when the hinges are of the type where the door panel must be raised somewhat in order to bring the hinge plates together.

The example illustrated discloses only the actual inventive idea, and other embodiment examples may readily be envisaged which are also within the scope of the invention, for example with other locking mechanisms than the resilient lip illustrated.
