3 Claims. (Cl. 22-241) This invention relates to improvements in door fasteners for hinged doors.

One object of the invention is to provide in a door fastener comprising a rotary operating bar having keeper engaging crank members thereon cooperating with fixed keepers and actuated by an attached operating handle lever, stop means for arresting rotation of the bar to hold the operating handle lever spaced from the face of the door when the door is open.

A more specific object of the invention is to provide stop means in a mechanism of the character specified in the preceding paragraph comprising a bearing bracket or" guide for rotatably supporting the bar and a bearing element rotatable with the bar and supported within the bearing bracket, comprising a pair of blocks embracing the bar, the bearing element and bracket" having cooperating stop shoulders thereon for arresting rotation of the bar when the door is forced open to hold the operating handle lever spaced from the face of the door.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings forming a part of this specification, Figure 1 is a broken, front elevational view of a wall provided with a door opening, and a pair of hinged doors for closing said opening, illustrating my improvements in connection therewith. Figure 2 is a front elevational view, on an enlarged scale, of the operating bar and cooperating supporting bearing bracket of my improved mechanism, as shown in Figure 1, the top and bottom end portions of the bar being broken away. Figure 3 is a transverse, horizontal sectional view, corresponding substantially to the line 33 of Figure 2. Figure 4 is a plan view of the supporting bearing bracket shown in Figure 2, illustrating a step in the assembling of the mechanism and showing the bearing blocks being inserted within the bearing bracket. Figure 5 is a View similar to Figure 4,- illustrating a further step of the assembling operation and showing the bar being inserted between the bearing blocks. Figure 6 is a horizontal sectional view, corresponding substantially to the line 6--6 of Figure 2 with the bearing blocks and operating bar omitted. Figure 7 is a vertical sectional view, corresponding substantially to the line 1-1 of Figure 6. Figure 8' is a detail perspective view of one of the bearing blocks of my improved mechanism.

In said drawings, 10 designates the side wall member of a refrigerator ear, having a door 2 opening ll therein, which is closed by a pair of hinged doors [2 and I3. Each door member is provided with the usual sets of hinges i k- I4 along the vertical? outer edges thereof, by which the door is swingingly supported. The door Ii,

which is that first closed, and the door l3 have; meeting edges which are beveled and so inclined that the door i3 will maintain the door Ii in closed position and wedge the same shut when the door operating mechanism is actuated; The edges of the doors and the cooperating edges of the door frame are provided with the usual insulating packing material, not shown.

My improved door fastener mechanism roper comprises broadly a rotary operating bar A; a pair of keeper engaging end castings B-fi; an operatinghandle lever C; top and bottom guide brackets D'l for supporting the operating bar; a pair of keepers with which the end castings cooperate; an intermediate guide or" beari'ng bracket F' supporting the bar A between its top and bottom ends; and a pair of bearing blocks G-G within the bracket F embracing the operating bar A.-

The operating bar A is of substantiallyrectangular cross section and has the end castings B-B riveted thereto or secured in any dtlir similar manner. Eachcasting B' rotatably supported in the corresponding guide of bearing bracket D and has the usuai crank arm at the outer endthereof, which cooperates With" the corresponding keeper E in a well-known manner, the keeper having the usual cam slotiii which the keeper engaging projection of the crank ariii engages.

AS Sl'lOWl'i in Figllf 1, the ofiitlililg' bfii 6T shaft A is vertically disposed and the guide brackets D-D, which are preferably two in number; are employed to rotatably support the bar at the keeper engaging ends thereof. Thain-oer mediate guide bracket F'serves to rotatably sup- DOIt the bar A between its l'JOp and BOlil'lOfii fl'flS.

The guide or bearing bracket F comprises a main body bearing portion 15' and a pair or piate portions 16-46 extendin laterally from said body pOIlliOn and fdfl'fiifig' securing flanges f6? mounting the bracket on the door. The body portion I5 is of substantially cylindrical contour and comprises top and bottom, laterally extending, vertically spaced, curved strap members [1-41. The space between the strap members lll provides a guideway it? for a purpose hereinafter described. At theback of} the brackct F, anopening is is provided which extends from the top to thebottom of the bracket. This 3 opening is provided for the purpose of assembly and is of such a width as to admit the bar A edgewise and the bearing blocks GG lengthwise, as hereinafter pointed out. Adjacent the opening IQ of the bearing bracket, the plate portions |6|6 are slotted, as indicated at 2020. The slot-s 2020 extend horizontally and are curved, as most clearly shown in Figure 6. These slots form continuations of the guideway 8. At the points where the slots 20-40 merge with the guideway It, the front side of each plate member I6 is provided with a flat abutment face 2 l, which is located within the guideway l8. The face 2| is slightly inclined in lateral outward direction to provide flat contact with a stop shoulder on the bearing element composed of the blocks GG. The bracket F is secured to the outer face of the door I3 by any suitable means, such as bolts, extending through the iisangl e; portions formed by the plate portions The bearing blocks G-G are of similar design and are complementary to each other. The blocks GG are disposed within the bearing bracket F at opposite sides of the bar A in embracing relation thereto. Each block G comprises a partly cylindrical portion 22 having a laterally extending, exterior, arcuate rib 23 between the top and bottom ends thereof. The opposite end edges of the partly cylindrical portion 22 of each block G are squared off to provide straight abutment faces 2424 which bear fiatly on the corresponding side of the bar A. At the outer side, as seen in Figure 5, each block G is provided with a projecting stop lu 25, which is in horizontal alignment with the rib 23 and extends through the guideway I8 outwardly beyond the strap portions of the bracket F. The lug 25 presents a straight side face 26 adapted to engage and bear flatly on the abutment face or stop shoulder 2| of the bearing bracket, as clearly shown in Figure 3.

In assembling the bar A, bearing blocks G--G,

and the bracket F, the left hand block G, as seen in Figure 4, is first placed within the bracket F by passing the same into the bearing opening of the bracket through the opening H! at the back of the bracket. After this block has been properly seated in the bracket, the right hand bearing block is then placed therein, as shown in Figure 4, by passing the same lengthwise through the opening I9. After both blocks GG have been seated within the bearing bracket, as shown in Figure 5, the bar A is inserted between the blocks G-G by engaging the bracket F over the bar, the bar passing through the opening |9 of said bracket. The bracket F is then permanently secured to the door.

' As will be evident, the bar A serves to hold the blocks G--G spaced apart in completely assembled condition of the parts and the blocks are connected to the bar for rotation in unison therewith.

The operating bar A is rotated by the usual operating handle lever C, which is pivoted thereto to swing in a vertical plane and may be locked in position to hold the door closed by any wellknown latch means, indicated by 21.

Upon reference to Figure 5, it will be seen that the lug 25 of the left hand block and the stop shoulder 2| of the bracket F are so located as to stop rotation of the bar when the lever C is swung from the position shown in Figure 1 to a position adjacent and parallel to the door l3 but spaced from the face of the door, thereby providing clearance between the same and the door.

In Figure 1, the doors are shown in locked and closed position, the keeper engaging crank portions of the operating bar A being in engagement with the keepers and the operating handle 0 locked against rotation by the latch means 21, as is well-known in this art. To open the doors, the operating handle lever C is unlatched and swung from the position shown in Figure l to the right and inwardly .toward the door I3, thereby rotating the bar A and through the camming action of the crank members forcing the door open. The swinging movement of the operating handle lever C is positively arrested, before the same reaches a position where it would engage the door I3, by the stop lug 25 of the block G at the corresponding side of the bar coming into engagement with the corresponding shoulder 2| of the guide bracket F. The operating handle lever C being thus held clear of the door, marring of the finished surface of the latter is positively prevented when said handle lever is swung on its pivotal connection with the bar to drop to vertical position alongside the latter. This stop means also performs in the manner of a safety device, preventing the attendant from injuring his hand, which might otherwise occur by the same being caught between the handle of the lever and the door.
