Claims'.

'l0' for swinging movement about an axis passing vertically through the door and also about a parallel axis located adjacent one side edge of the door and at the side of the door opening, said means being so arranged that the door will have I5 a predetermined movement without the use of tracks or the like.

Another a-imI of the present invention is to provide an improved door mounting which' admits of easy operation by the application oi a relatively '2(1 small force thereto.

An object of the present invention is to provide an improved hanger for a door of this character which eiects the complete closing and opening. of the door when the door has been moved a predetermined extent towards either of: these positions. With this object in mind, my improvedhanger includes means forl automatically andy effectively moving the door to its fully open or fully closed position after the door has been partially manually moved to either ofthese-positions'.

Another object of the presentl invention is to' provide: an improved deviceofV this kind in which the door is free of a-ny obstructions .at the lower end of the opening in the wardrobe, either when the door is openor closed. Thus, Lthere are no parts over which children or other users of the device are apt toY stumble or trip. Such a structure alsosimplies the sweeping out ofthe wardrobe.

A further object of the present invention is to provide a device of this kind which is simple in construction, comprises few parts, and may be cheaply manufactured, admits of easy installation, and is not apt to get out of order.

Other objectswillbe in part obvious, and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exempli- 150 ed; in the construction hereinafter set forth and the scope of the application of whichv will be indicated in the appended claims.

In the accompanying drawings, wherein is4 shown, for illustrative purposes, one embodiment 1 55 which the present invention may take,

1932',A Serial No. 639,465'

Fig.v 1 is a rear elevation,` with parts broken away, of a door anda frame therefor with my improved door hanger applied thereto;

Fig..2 is a top plan viewof the same with parts broken away and parts inv section.;` and Fig; S'isan end" view ofv they same with parts broken away and parts in section.

ReferringM more particularly to the drawings, A generally designates awardrobe or the like having an openingbounded by a frame upon which is hung:A a door C by means of my improved door hanger or carrier, generally designated D.

Whil'e'the Wardrobe is here shown as having. one opening and one door, it is to be understood that the wardrobe may be of any desired size and may be provided with as many openings and doors as desired..

The door frame, which may be of any suitable construction,. has a lntel 5 extending across the top of the opening ofthe wardrobe A, and side uprights 6 and 7. The doorway may have the usual casing comprisingY the overhead' member 8f and upright side members 91 and 10`, the latter of which constitutes a j'amb for one edge of the door. Secured to the rear edge of the upright 6 is a jvamb stripv ll.

Secured at spaced apart points. to the inner face of' thev side member 10 are.y a plurality of bracketsr 16, These brackets 16 are provided with a. suitable. number of openings adapted to receive screws 17 or the like by means of which the brackets are attached to the member 1.0. The lowermost bracket is provided with two spaced apart shelves or ledges 18 and. 19 each of which is.. disposedfat substantially right angles to the main` body portion. of. the bracket, while each of the center and upper brackets has only one such shelf 181. All Aof thesel shelves. 18 and 19` are provided with. aligned openings through which passes a shaft. 20. Intermediate the shelves 18 and 19. of thelowerbracket 16, the shaft 20y has an arm 2l 'xed; thereto by means of set screws 22 orsfthe like.

The free. endof. the arm 21 is provided` with an opening. which receives. a pivot pin 23 carriedby a. pivot plate 24, mounted upon the lower portion ot the door closer to. the side edge thereof. which is adjacent. tof the shaft 20` when the door is in closed position, than the outer edge. The plate24 may be securedto the doorv by means of screws 25 or other suitable iastening'means. Disposed be'- tween the; bottom. of, the arm 2l andv the upper face. of. the shelf' 1.9i of the lowermost bracket 16 and surroundingtheshaft 20-is a' ball race 26containing ball bearings Sli fili;

'i otal connection 33 past'dead center.

The upper end of the shaft 2O extends upwardly beyond the shelf 18 of the upper bracket 16, and xed to this upper extended end portion of the shaft 20 is an arm 28. The free end of the arm 28 is provided with an opening which receives a pivot pin 29 carried by a pivot plate 30 mounted upon the top portion of the door C, the pivot plate 30 and its pivot pin 29 being in vertical alignment with the pivotA plate 24 and its pivot pin 23 respectively. The pivot plate 30 is fixed to the door C by means of screws 31 or the like.

The plate 30 carries an arm 32 which may be formed integral therewith, and extends therefrom inwardly of the door. The free end of this arm 32 has pivoted thereto, as at 33, a link 34. The pivot 33 may be in the form of a rivet so as to prevent the separation of the arm 32 and the link 34. The other end of the link 34 is pivotally received by the reduced end of a stud 35, and is held thereon by means of a cotter pin 36 which passes through an opening in the free end of the stud. The stud is xed to an attaching member 37 which is mounted upon the under surface of the lintel 5 to which it may be secured by means of screws 38 or the like. A coil spring 39 surrounds the stud 35 and has one end thereof secured to the member 37, as by a rivet 40, and the other end secured to the link 34, as by a rivet 41. The spring 39 is so formed and arranged that when the pivotal connection between the arm 32 and link 34 is past dead center, when the parts are moving to either an open or a closed position, it will tend to move the link 34 toward the inner side of the door C and thereby complete the opening or closing operation, as the case may be.

' It is thus apparent that the door C will be automatically opened or closed without the necessity of applying enough force to completely open or close the same provided enough initial manual force is applied to carry the parts past dead center.

It is'also noted that the shaft 20 and the lower arm 21 are carried by the frame above the lower end thereof and, therefore, the arm 21 and shaft 20 will be spaced from the iiloor upon which the wardrobe stands and that no threshold is employed s0 that there will not be any parts over which the users of the wardrobe may stumble and so that any dirt or waste material which may accumulate on the floor will not interfere with the proper operation of the door and may be readily swept out of the wardrobe.

` `In the operation of the device, assuming that the door C is in the closed position, as indicated inr full lines in Fig. 2, and it is desired to open the door, force may be applied to the door at any point along the edge thereof adjacent the shaft 20. This will impart to the door swinging movement so that the various parts will be moved to the position indicated in dotted lines at the extreme right-hand end of Fig. 2. During the initial movement of the parts toward open position, the arm 32 forces the link 34 inwardly ofthe wardrobe against the tension of the spring 39 until the parts have moved suiciently far to carry the piv- The line a-a of Fig. 2 indicates the dead center line. The spring 39 will then become effective to move the link 34 to the dotted line position of Fig. 2 referred to above, thereby moving the door C and other parts to full open position. To close the door, force is applied to the outer edge of the door and, as the parts move toward the full line position of Fig. 2, the arm 32 moves the link'34 inwardly of the wardrobe against the tension of the spring 39 until the connection 33 is moved past dead center in the opposite direction. The spring 39 will then take effect to move the parts into complete closed position shown in full lines in Fig. 2.

It will be noted that the door C, during its opening and closing movements, pivots about the pivot pin 29, as an axis, which is parallel to the pivotal axis of the arms 2l and 28 and that the arm 32 and link 34 guide the door in its pivotal movement about its axis 29 until the parts have passed dead center. The spring 39 then becomes effective to complete the opening or closing movement of the door, as the case may be, in the manner described above.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all o-f the generic and specic features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
