DOOR OPERATING DEVICE Filed 'May l. 1930 Patented Nov. 17, 1931 UNITED STATES PATENT OFFICE I JAMES E. BALES AND CARL T. CHRISTENSEN, OF AURORA, ILLINOIS, ASSIGNORS TO LYON METAL PRODUCTS, INCORPORATED, OF AURORA, ILLINOIS, A CORPORATION OF ILLINOIS DOOR OPERATING DEVICE Application mea May 1,
This invention relates to a cabinet door operating device and particularly to an operating device for swinging doors.
The primary object of the invention is to provide a door operating device which will assist in opening a swinging door when it is swung a predetermined distance and which will close the door when it is moved a predetermined distance toward shut position.
Another object is to provide an improved spring controlled device for keeping a swinging cabinet door in closed position 'and which assists in opening a swinging door when it is opened a predetermined distance.
A further object is to provide a new and novel device of simple construction which will maintain a swinging door in closed position, which permits the door to be opened easily, and which assists in closing the door when it is moved toward closed position a predetermined distanceJ A still further object is to provide a cabinet door operating device for swinging doors which is efi'icient in operation and which can' be readily and economically manufactured. Numerous other objects and advantages will be apparent throughout the progress of the following specification..
The invention comprises in general a bracket member which is ada ted to be fastened to the inside of a door jamb. A member is pivotally connected to the bracket and vhas a roller mounted on its fiee or outer end. A bolt is loosely connected to the member and a flange on the bracket to permit movement of the member relative to the bracket. A spring is arranged about the bolt and confined between one face of the member and a flange on the bracket. A roller engaging member is fixed to a swinging door and acts against the tension of the spring. This door engaging member is provided with faces against which the roller engages. When one lface of the door engaging member 1s engaged with the roller, the door will be. maintained iii shut position. When the door is opened, the door engaging member. will move the member against the tension of the spring so that the door can be mopened. As soon vas a high point provided on the door yengaging 1930. Serial No. 448,914.
member passes beyond the roller, the roller will engage the other surface and tend to push the door outwardly. In closing, the roller member is firstl pushed against the ten sion of the spring until the roller rides over the high point of the door engaging member. As the roller passes over the high point of the door engaging member, it will engage the other roller contacting surface and pull the door shut.
The accompanying drawings illustrate a selected embodiment of the invention and the views therein are as follows:
Fig. l is a detail front elevation of acabinet or other structure upon which the inven tion is applied.
Fig. 2 is a transverse sectional View on the line 2 2 of Fig. 3. l
Fig. 3 is a detail elevation partly in s ection showing the improved door operating device.
Referring to the drawings, 5 designates vertical uprights between which aframe 6 1s arranged. Hinges 7 are operatively connected to the frame 6 to swingingly hold doors 8 in position. The doors 8 may be p i'ovided with handles or knobs 9 for opening and closing the same. The uprights 5 and the frame 6 are referably made of sheet metal and may be astened together by means of a bracket 10 which is operatively connected to the uprights andto the frame. The bracket may be fastened tothe upright in any convenient manner such as by welding, and it may be'fastened to the frame in any convenient manner such as by employing threaded members 11, Fig. 2. The bracket has a substantially horizontal body portion 12, a rear upturned angel, and a front downturned flange 14. The downturned ange 14 engagesthe inside of the uprights and frame as clearly shown in Fig. 2.
A roller arm 15 which is preferably made of sheet metal and preferably formed channel-shaped is pivotally connected to the body 12 of the bracket as indicated at 16. The back 17 of the channel-shaped member 'is cut away at 18, Fig. 2, and the sides 19 of the channel-shaped member are extended angularly to provide a pair of spaced ends 20"be tween which a roller 21 is revolubly mounted.
A bolt 22 extends through the back 17 of the roller arm 15 and through the vertical flange 13 on the bracket 10, a nut 23 being provided on the end of the bolt to hold it in position. A spring 24.- surrounds the bolt 22 and is restricted between the back 17 of the `member 15 and the upturned flange 13 on the bracket 10. lThe roller arm 15 is, therefore, permitted to 'swing on its pivot against the tension of the spring 24, its movement being restricted by the length of the bolt 22.
A metal plate 25 is fixed to the inside of a door 8 and has its outer free end 26 bent to provide a cam member 27 having cam surfaces 28 and 29. The roller 21 is adapted to engage vthe surfaces 28 and 29 of the cam member 27. In the position shown in Fig. 2 the roller 21 is engaged with the cam surface 28 to hold the door in closed position, the roller arm being 'affected by the tension of the spring 24 thereagainst. In opening, the door is pulled b v its handle 9 until the roller 21 passes over the high point 30 of the cam member, the opening of the door compressing the spring. As the door is being opened, the roller 21 will bear against the cam surface 29 and due to the spring pressure against the roller, assists in opening the door. In closing the door, the roller 21 will be engaged with the cam surface 29. Pressure against the door causes the roller arm to move rearwardly against the tension of the spring 24 until the roller 21 passes the high point 30 of the cam member. As soon as the roller passes over the high point 30, the action of the spring against the roller arm causes the roller to be pressed aga-inst the cam surface 28 to assist in closing the door and kp it in closed position. The invention provides a simple and inexpensive device for assisting in opening and closing swinging doors and for maintaining them in closed position. The bracket arm assists in holding the frame to the upright and also provides a simple and inexpensive support for the door roller. The roller` arm is preferably made out of sheet metal which is bent to the proper form and configuration. The entire device is efficient, can be applied to existing doors and frames, and may be readily and economically manufactured. f
Changes may be made in the form, construction, and arrangement of the various parts without departing. from the spirit of the invention or sacrificing any of its ad vantages, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claims.
The invention is hereby claimed as follows: 1. In combination, a plate having a turned ledge for fastening the plate to a door j amb, a channel-shaped. arm pivoted to said plate and having spaced ends, a roller pivoted to said arm and arranged between said spaced ends, a turned ledge on said plate, a bolt passing through said ledge and arm and loosely connecting said arm to said ledge, a spring about the bolt and urging the arm in a predetermined direction, a plate adapted to be applied to a door in juxtaposition to said roller and having a triangularly-shaped end for engagementwith the roller when the door is in certain positions, said rolleI` engaging one side of said end and holding the door in closed position, said roller tending to push the door open when engaging the other side of said end.
2. In combination, a horizontal plate hav ing a ledge bent therefrom for fastening the plate to a door jamb, a U-shaped arm pivoted r to said plate and having spaced ends, a roller pivoted to said arm andai-ranged between said spaced ends, a second ledge bent on said plate, a bolt passing through said arm and said second ledge and'loosely connecting the armto said ledge and limiting the movement of said arm, 'a spring about the .bolt between the ledge and the. arm and urging the arm in a predetermined direction, a plate adapted to be applied to a door in juxtaposition to said roller,y said last named plate being bent to form a triangularly-shaped member adapted to be engaged by the roller when the door is in a certain position, said roller engaging one side of said member to hold the door in closed position, said roller tending to push the door open when engaging the other side of said member.
In witness whereof, we have hereunto subscribed our names.
