HINGE Filed Nov. 18,l 1938 Patented May 7, 1940 UNITED STATES PATENT OFFICE HINGE Application November 18, 1938, Serial No. 241,154 In Switzerland November 22, 1937 2 Claims.

'The present invention relates to a hingefor doors, windows, furniture and so forth.

1 The new hinge consists of parts which preferably agree in pairs inIshape and dimensions and which are all connected together hingedly. None of the parts is subjected to excessive strain which would lead to a change of shape of the parts or to a rapid wear thereof. All the parts of the hinge are invisible when the door or the like is closed. They t into recesses in the door frame, door panels and so forth. The parts of the hinge may consist of extrusion castings or be formed of sheet metal b-y stamping and pressmg. E

An example of construction in accordance with the invention is shown in the accompanying drawing, wherein.

Fig. 1 is a plan of the open hinge.

Fig. 2 is a corresponding plan of the closed hinge.

Fig. 3 is a side elevation.

Figs. 4 to 9 each show a partial elevation of the six separate parts forming the hinge, witho-ut the hinge pin, and

Figs. 10 to 19 are sections respectively on the lines X-X to )HX-XIX of Figs. 4 to 9.

The rst hinge plate I is provided With screw holes 2 for the purpose of enabling it to be secured to one of the parts to be connected. The hinge joint located adjacent the said screw holes, is provided with three coaxial hinge eyes 3, projecting above the hinge plate, which are separated from one another by intervening recesses 4. The hinge joint remote from the screw holes and extending parallel to the hinge eyes 3 is preferably in alignment with the edge of the hinge plate. It is also provided with three coaxial hinge eyes i5, projecting above the hinge plate, which are separated by recesses 6. The arrangement of the last mentioned hinge joint is preferably such that the hinge eyes 5 are opposite the recesses 4 and the hinge eyes 3 are opposite the recesses 6.

The ilrst connecting band 1 is provided on both sides with symmetrically arranged hinge eyes 8 and 9, which are so arranged that they t into the recesses 4 of the hinge plate I. By means of abutments I I, provided on the connecting band 1, the hinge is prevented from being rocked beyond a predetermined open position. f

The irst main hinge band I2 is of angular shape as shownin Figs. 14 and l5 and is provided with three hinge lugs I3 at the ends of which are provided the downwardly directed coaxial eyes I5, which fit into the recesses 6 of the hinge plate I and for this purpose are spaced apart by the recesses I6. In the base of the lugs, which is located approximately at the centre o-f the width of the main hinge band I2, are provided the main hinge eyes I1. Opposite the recesses I6 there are provided at the other vend of the main hinge 5 band I2, hinge eyes I8 which are separated from one another by recesses I9.

The second main hinge band I2 is provided in the same manner as the first main hinge band I2, with hinge lugs I3', hinge eyes I8', hinge eyes 10 I5, recesses I6 and I9 and main hinge eyes I1', of which the dimensions are such as to enable the hinge to be assembled in the manner to be described hereinafter.

The second control band 1', shown in Figs. 12, 15 13 and 8, is provided in a similar manner to the first control band 1 with hinge eyes 8 and 9', and abutments II.

The second hinge plate I is of the same construction as the first hinge plate I and consequently is provided with screw holes 2, hinge eyes 3 and 5 and with recesses 4 and 6.

The assembly of the parts sho-Wn in Figs. 4 to 19 for forming the hinge capable of being used is effected in the following manner. The control band 1 or 1 is iitted into the recesses 4 or 4' while the hinge eyes 3 or 3' come to lie on the hinge eyes 8 or 8', so that a hinge pin can be passed through the hinge eyes located along an axis and thus form a hinged connection between the hinge plate 30 I or I and the control band 1 or 1. The main hinge bands I2, I2 are sov arranged crosswise that the hinge eyes I5 and I8 or I5' and I8 are located on the same side of the hinge and the main hinge eyes I1 and I1 are located along one and the same axis so that they can be connected together hingedly by a hinge pin passed therethrough. The hinge eyes I5 or I5 are brought into a position so` as to lie coaxially with the hinge eyes 5 or 5' by reason of the recesses 40 6 or 6 so that the hinge plate I or I is hingedly v connected to the main hinge band I2 or I 2'. The control band 1 or 1 is connected by its hinge bands 9 or 9' to the hinge bands I8 or I8 by meansof a hinge pin, whereby during the closing 45 movements the main hinge joint carries out a positive parallel movement to itself into the interior of the hinge by reason of the double hinge action.

For applying the present hinge to articles of 50 furniture, doors, Windows and the like, the hinge 'plates I and I are counter-sunk as shown in Figs.

l and 2, so that when the hinge is closed none of the ittings are visible.

In comparison with known hinges which are 55 not visible in the closed position, the present hinge possesses the great advantage that the parts thereof co-operate with one another exclusively hingedly, whereby neither wear, which produces increased relative movement of the separate parts, or increased resilient deformations are produced, which deformations always involve the liability of fractures as a result or" fatigue. vThe hinge according to the present invention is preferably produced by the extrusion casting process or from sheet metal by the stamping process. v

I claim:

l. A hinge comprising a pair of base plates, two sets of apertured lugs on each of said base plates, one set of lugs being located adjacent one longitudinal edge of the base plates and the second set of lugs being arranged parallel to the first set but relatively displaced thereto, said base plates having recesses between said apertured lugs, a pair of double-armed levers arranged crosswise to one another, the arms of said levers, being at an angle to one another, said levers having lugs and recesses located along the centre line thereof, the recesses of one lever being adapted to receive the lugs of the other lever, said lugs being apertured, a hinge pin extending through the' lugs of said levers, one arm of each of said levers having spaced lugs arranged at right angles to said arm, the right-angled lugs of one lever being hingedly connected tothe lugs at the edge of one plate,

while the right-angled lugs of the other lever` are hingedly connected to the lugs at the edge of the second plate, spaced apertured lugs at the ends of the other arms of said levers, and a pair of links, one link being engaged with the lugs at the end of one lever arm and the inner set of lugs o-n the corresponding plate, while the second link is hingedly connected to the lugs of the second lever and to the second set of lugs on the corresponding plate, the whole arrangement for the purpose that the plates with the .lugs and levers form a closed protecting surface against dirt in all positions of the hinge.

2. A hinge according to claim 1, wherein the separate parts are so dimensioned that in the open position of the hinge the links rest against the levers which form a stop for said links, by

virtue of the who-le arrangement the plates will` always reach exactly the saine open position and no excessive strain will be exerted on the plates. MARIE WITSCHT.
