Dec. 15', 1959 R. w. ATEN HINGE CLIP Filed Aug. 16, 1954 [oooool INVENTOR. RALPH W. ATEN United States Patent HINGE CLIP Ralph W. Aten, Swan Creek, 11]., assignor to Admiral Corporation, Chicago, 11].

Application August 16, 1954, Serial No. 450,053 6 Claims. (Cl. 126-194) The present invention relates to hinge structures and to the combination of a hinge structure and a door and more particularly to an improved hinge structure for the oven doors of ranges by means of which the door may be easily and quickly mounted upon or removed from the range.

In doors for appliances and more particularly for the oven of ranges, it is desirable to provide a hinge structure by means of which the door may be readily mounted upon the range and quickly removed therefrom at desired intervals to provide access to the oven or to adjustable brackets arranged within the range which have a portion extending through an opening in the inner wall of the door and upon which the door is pivotally mounted. It is particularly desirable that the mounting be such that the door may be assembled apart from the range and quickly connected to the range without disassembly.

It is an object of the present invention to provide a hinge structure for doors and particularly for the doors of the oven of a range in which improved means are provided for pivotally mounting the door on the range including means for resiliently maintaining the pivoting means in place.

Another object of the invention is to provide an improved hinge structure for pivotally mounting a door upon a bracket in which resilient means are provided which may be actuated in one direction to remove the pivoting means from a bracket on which the door is mounted and in which the pivoting means may be first retracted and then released to enable the door to be again mounted on the bracket.

A further object of the invention is to provide the combination of a door with an improved hinge structure including a bracket upon which the door is pivotally mounted and in which resilient means are provided for maintaining the pivoting means in place when the door is mounted on the bracket and in which the door is provided with a slot through which an instrument may be inserted to engage the resilient means to move the pivoting means in one direction against the force of the resilient means so that the door may be removed from the bracket and in which the door may be again mounted upon the bracket when the door is installed in place and the force upon the resilient means is released.

The invention, will be better understood by reference to the accompanying drawings in which:

Fig. 1 is a front elevational view of the hinge structure with the outer cover of the door removed and showing one of. the side frames and the inner wall of the door, parts of which are broken away;

Fig. 2 is a rear elevational view of the inner wall of the door with parts broken away, and the horn-shaped portion of the bracket for supporting the door being shown partly in cr'oss'section;

' Fig. 3 is a side elevational view of the pivot pin utilized in the hinge structure;

ice

Fig. 4 is an enlarged vertical medial cross sectional view of the hinge clip and illustrating the hinge pin in position;

Fig. 5 is a fragmentary sectional view showing the mounting of the oven door on the range housing, the door being shown in section taken along the line 5 5 in Fig. l; and

Fig. 6 is a view similar to that shown in Fig. 1 with the pivot pin shown in its retracted position to enable the oven door to be assembled upon or removed from a bracket secured to the range.

While the improved hinge structure of the present invention is of general application and may be utilized in connection with door structures of any desired type in which the door is pivotally mounted on brackets, for

purposes of illustration, it is shown associated with the door of an oven for ranges which door is designated generally by the numeral 1 and which is provided with a pair of side frames 2 arranged within the door, only one of which is shown. In pivotally mounting oven doors on ranges, it is the practice at the present time to provide a pair of brackets which are usually arranged within and secured to the front wall of the range and which are preferably adjustably mounted in place as shown more particularly in Serial No. 449,932, filed on even date herewith, now Patent No. 2,823,663.

As illustrated in the copending application to which reference has been made and as shown in the present drawings, a bracket 25 is provided having a horn-shaped portion 3 which extends through an opening 30 in the rear wall 20 of the door and terminates in a downwardly extending porti0n4 having an aperture therein and, in accordance with the present invention, an improved hinge structure is provided for pivotally mounting the oven doors in place which pivoting means may be easily withdrawn from the aperture in the bracket when it is desired to remove the door from the range. The bracket 25 is,

suitably secured to the inner face of the front wall 31 of the range housing, as shown in Fig. 5 herein and more particularly described in the copending application referred to. t

In addition to its back wall 20, the oven door has an consequently only one of. the hingestructures is shown.

It may be stated, however, that if the door is provided with only a single pivoting means, a single bracket and one hinge structure may be suflicient.

As shown in Fig. 1 of the drawings, the frame 2 of the door is provided with an outwardly extending flange 5 which may be secured to the door by suitable means,

such as welding, and is also provided with an'aperture adjacent its lower end through which a pivot pin 6 is adapted to extend when the bracket 25. Secured to the frame 2 of the door by suitable means, such as rivets 7,

bracket 25 and then extends downwardly and terminates in a substantially U-shaped bottom portion providing. spaced arms 9 and 10, each of which is provided withan aperture which apertures are in alignment with e'achother and the aperture in frame 2 and also with the ap'ei'tui e in the downwardly extending portion 4 of the bracket 25 when the door is mounted upon the bracket,

Patented Dec. 15, 1959 door is mounted upon the is a support.8 which" is inclined inwardly relative to the neck portion 3 of the' in'its operative position. The leaf'spring 11 is of a sub stantially inverted U-shape, one of the legs of which is provided with an aperture to receive the pivot pin 6. The otherleg 13 of the leaf spring is provided with inwardly extending flanges 14 and 15, Fig. 4, which stitten the spring at this point and are provided with aligned apertures'18, Fig. 1, arranged adjacent pin 6 when the door is'pivotally mounted on the brackets. The leg 13 is also providedwith a central aperture 16 and a slot 17, which extends-to the extremity of the leg. The edges of which slot are. cutaway to provide a seat for engagement with pin in the groove 12.

The leg-13 of leaf-spring 11 is biased outwardly so that when the door is pivotally mounted on the. brackets, it will maintain the pivoting pin in place. In accordance with the present invention, means are provided which are accessible from outside of the inner wall of the door to move'the spring leg 13 and hence the pin 6 to the left as shown in Fig. 6 for removing pivot pin 6 from the frame 2 and the horn portion 3 of the bracket 25.. For this purpose,'the aligned apertures 18 provided in flanges 1-4 and 15 are opposite to a slot 19 provided in the inner wall 20 of the door, the slot also being in alignment with the apertures 18 in flanges 14 and 15 of the leaf spring. A pointed'instrurnent, such as a pin, not shown, may be'inserted through the slot 19 and into one or the other of the-aligned openings 18 to move the leg 13 of the leaf spring toward the left to the position shown in Fig. 6, thereby retracting or withdrawing the pivot pin from the aligned apertures in frame 2 and the lower portion of bracket 25; The other pivot pin on the opposite side of the door is removed from the frame and the other bracket in a similar manner. Upon release of leg 13 of the leaf spring, it willof course'assume the position shown in Fig;

l and-when it is desired to again mount the door upon the brackets, the leg 13 of the leaf spring may again be moved toward the left from the position as shown in Fig. 1, the door may be arranged to receive the hornshaped portion ofbracket 25 at which time the apertures in support 8 and frame 2 may be aligned with the aperture in the downwardly extending portion 4 of the bracket and when the leg 13 of the leaf spring is released, the pin passes through thehorn and wall 2 and the door is thus pivotally mounted on the bracket.

As shown in the drawings and more particularly in the copending application to which reference has been made, the plate 21 of a connector is also secured between the frame 2 of the door and the support 8. Plate 2 1 extends through the opening in the rear wall 20 of the door and is connected at its lower end to suitable counter balancing springs. V Y 7 It will thus be seen that I have provided a hinge connectron which is very easy and economical to install. It may also be installed quickly and without special tools since an ice pick, nail or similar article may be used to engage with the aperture in the spring. It is also important tonote that the door may be completely assembled apart from the range along with the spring device and thetfinal attachment of the door readily made after assembly of the other parts without dismantling the door.

Having thus described the invention it will be apprecrated that numerous and extensive departures may be made therefrom without departing from the spirit of thznivention as defined in the appended claims.
