June 11, 1957 T. P. FOLEY ADJUSTABLE DOOR BRACE CONSTRUCTION Filed April 28, 1955 FIGJ INVENTOR.

THOMAS P. Fol-EY HIS ATTORNEY States 2,795,015 ADJUSTABLE DOOR BRACE CONSTRUCTION Application April 28, 1955, Serial No. 504,514 Claims, (Cl. 20-3S) Unite My invention relates to braces for heavy doors, such as refrigerator doors, and more particularly to an adjustable door brace construction for permitting adjustment to alter the shape of the door.

In the building of refrigerator cabinets Iand the like on a mass production basis the plane of the door in the completed cabinet is sometimes not entirely parallel to the plane of the face of the cabinet. Such a condition may prevent the proper sealing of the door. Provision may be made by the use of adjustable diagonal cross braces for varying the plane of the door to bring it into coincidence with the plane of the face of the cabinet. But when a door liner having a deep recess for the accommodation of door shelves is included in the door structure, difliculties have been encountered in providing a suitable bracing arrangement of this sort. The braces must be set back a considerable distance from the inner face of the door to allow clearance for the liner recess, but yet they must be readily adjustable after the liner has been mounted in place.

Therefore, it is an object of my invention to provide a new and improved adjustable door brace construction for refrigerator doors.

It is another object of my invention to provide a sirnpliied adjustable door brace construction including diagonal braces set deep within the door and adjusting means for the braces readily laccessible at the inner face of the door after the door is completely assembled.

A further object of my invention is to provide an improved adjustable door brace construction which is very inexpensive to manufacture and assemble within a refrigerator door.

In carrying out my invention I provide an adjustable `cross brace construction for a refrigerator door of the type having an outer shell and an inner liner. The cross brace construction includes two diagonal cross braces which exten-d between diagonally opposite corners of the shell. Mounting members for the braces are attached to the shell at the corners, and by my invention, I provide an improved arrangement whereby the braces are adjustably secu-red between these members. In this arrangement, each brace is more or less rigidly secured to one of its opposite mounting members and is secured to the other by a movable bracket. This movable bracket includes a body portion and a pair or" oppositely extending legs, one of which is attached to the brace and the other of which engages the mounting member. The bracket is held by a bolt extending between it and the mounting member, and the bolt and the mounting member are so arranged that they engage through rounded surface means. The bolt, in addition to holding the bracket, also serves as the means whereby the brace is adjusted. When the bolt is tightened, it tilts on the rounded surface means and thereby causes the bracket to pivot on the end of its leg engaging the mounting member. This pivoting of the bracket in turn applies tension to and tightens the brace, and thus results in a variation of the plane of the door to bring it in line with the face of the refrigerator cabinet.

The novel features which I believe to be characteristic Vof my invention are pointed Iout with particularity 4in the atent Fig. 1 is a front elevation view of a refrigerator having a door incorporating one embodiment of my cross-brace construction;

Fig. 2 is an elevational view of the inner face of the refrigerator door, the door liner being broken away to show details of the cross-brace construction;

Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2;

Fig. 4 is a sectional View taken on the line 4-4 of Fig. 2; and

Fig. 5 is a view similar to Fig. 4 showing an alternate embodiment of my invention.

Referring now to Fig. 1, I have shown therein a refrigerator 1 having a large door 2 for closing the access opening to its refrigerated compartment. A handle 3 is provided for tripping the door latch and opening the door. As is better shown in Figs. 2-4, the door includes an outer shell 4 of dished or pan-like construction. The shell 4 is preferably formed of relatively thin sheet metal and it includes a principal panel 5, an inwardly extending wall 6 which extends completely around the panel 5, and an inturned flange 7 at the inner end of the wall 6. The panel 5, as shown, comprises the outer wall of the door. Mounted on the shell 4 by means of the inner flange 7 is a door liner or inner wall 8. This door liner 8 includes a relatively deep recess 9 for accommodating a plurality of door shelves 10. The liner 8 is formed of suitable heat insulating plastic material so that no breaker strip is required between the flange 7 and the liner. The space between the shell 4 and the liner is however generally lled with suitable heat insulating material (not shown), such as fiber glass, in order to minimize heat leakage through the door. A sealing gasket 11 is mounted between the outer edge of the liner 8 and the flange 7 so as to seal olf the refrigerated compartment of the refrigerator when the door is closed. The means whereby the liner 8 is secured to the tlange 7 are not shown since it will be understood that any suitable means may be used.

A plurality of corner braces or

gussets

12, 13, 14 and 1S are secured diagonally across the corners of the outer shell. These braces or gussets stitfen the shell and tend to prevent its deformation. The ends of the gussets are welded as indicated at 16 to the flange 7 of the shell.

During the manufacture of the refrigerator there may be some variation in the shape of the cabinet or the shape of the door so that the plane of the door, and particularly the plane `of the sealing surface of the gasket 11, and the plane of the face of the cabinet are not parallel. This introduces the possibility of a gap between the sealing surface of the gasket and the face of the cabinet at some point. ln order to provide for adjustment to bring the plane of the door and the plane of the face of the cabinet into

coincidence cross braces

17 and 18 are provided. These cross braces extend respectively between diagonally opposite pairs of the corner gussets. Specifically, the brace 17 extends between the

gussets

12 and 14 `and the brace 1S between the

gussets

13 and 15.

According to my invention I have provided new and improved means whereby these

cross braces

17 and 18 are mounted and adjusted. These means allow the braces to be mounted deep within the door so as to allow room for the recess 9 of the liner but yet permit the ready adjustment of the braces even after the door has been com-y pletely assembled. In this arrangement the corner gussets serve as the mounting members for the braces. rl`he two braces are mounted identically by means of their respective gussets so that the mounting of only one brace will be described herein. Speciically, the mounting of the brace 17 will now be described.

As shown, the brace 17 comprises a rod or wire having hooked portions 19 and 20 provided at its opposite ends. The lower end of the brace is mounted from the lower corner gusset 14 by a rigid spacing means, such as, for example, `the bolt member 21.` The bolt member 21` extends inwardly into the door from the gusset 14, and is secured to the gusset by a suitable threadedrportion 22 which is screwed into a tapped aperture 'in the gusset. At its opposite or inner end the bolt member 21` `includestanaperture 23 through which the hooked end portion 19 of the brace, 17 is tted. This engagement between the bolt member and the hooked portion 19 ,serves to mount tixedly the lower end of the brace. It will be understood, of course, that other equivalent rigid members such as arms formed integrally with the gusset 14 could be substituted for the separate bolt member 21.` Y

The opposite end of the brace 17 is adjustably mounted by means of a novel arrangement `which is` supported from the corner gusset 12. This arrangement includes a bracket 24 `which has a principal body .portion 25 and two

legs

26 and 27. The legs 26 `and 27 specifically extend in opposite directions at the ends of the body'portion 25. The leg 27 extends inwardly into the door and near its inner end includes an aperture 28. The hooked end portion of the brace is inserted through this aper ture 28 and the bracket `24 thereby serves to mount the upper end of the brace. The other leg 26extends outwardly toward the inner face of the door and at-its outer end engages a flange 29 of the corner gusset 12. By comparing Figs. 3 and 4 it will be seen that the bracket 24 spaces the upper end of the brace the same distance inwardly from the inner face of the door as the bolt member 21 spaces the lower end of the brace. This spacing allows sucient space for a deep recess such as the recess 9 to be formed in the door liner 8.`

The bracket 24 serves as the means whereby the brace 17 is adjusted, the bracket being movable to `effect the adjustment. Thus, for mounting the bracket 24 there is provided a bolt or fastening means 30.' This bolt `30 extends through apertures 31 and 32 `in the gusset 12 and the body portion of the bracket respectively. Mounted between the head 33 of the bolt and the gusset 12 `is a rocking member or washer 34 andmounted on the end of the bolt at the remote side of the body portion 25 of the bracket is a rocking member or nut 35. It will be noted that both these rocking members include a rounded surface. Thus the rocking member or washer 34 includes a rounded surface which engages the gusset 12 and the rocking member or nut 35 includes a rounded surface which engages the body portion 25 of the bracket. It will also be noted that the nut 35 includes a llatted surface 36 `which engages the leg 27 of the bracket to prevent turning of the nut as the bolt is turned.

The action of these rocking members is effective to cause adjustment of the brace as the bolt is tightened. Specifically, as the bolt is tightened, these rocking `members cause the brace to be tightened, and this in turn adjusts the plane of the inner face of the door so that it coincides with the plane of the face of the refrigerator cabinet. The action produced by these rocking members is shown by the dotted lines in Fig. 4. As the bolt is tightened, the nut 35 does not rotate and therefore is pulled toward the washer 34. This causes the bolt to tilt on the rounded surface of washer 34 and that in turn causes the bracket to pivot on the end of its leg 26. In other words, the tilting of the bolt causes a pivoting of the bracket around the point at which the leg 26 engages the gusset 12. The pivoting is toward the right as viewed in Fig. 4 so that the brace 17 is placed under tension. ln other words, the distance between the bolt member 2l. and the end of leg 27 is lincreased as the bracket pivots and this pulls on the brace and places it under tension. By continuing the turning of the bolt a suflicient movement of the bracket and the end of the brace may be effected to adjust the plane of the door to the desired position,

In the embodiment of Figs. 1-4, the cross braces may be adjusted after the door is completely assembled. It will be noted that in my preferred embodiment the head 33 of the bolt 30 lies adjacent the door liner 8. In other words, .it is adjacent the inner face of the door. In order that the bolt may be turned and the cross brace adjusted after the door is completely assembled, I have provided suitable means for inserting a tool through the liner 8. This means comprises a removable cap or button 37 which is positioned over an aperture 38 in the liner. This aperture 38 directly overlies the head 34 of the bolt so that when the cap 37 is removed, a toolmay be brought into direct contact with the bolt for turning it.

Referring now to Fig. 5, I have shown therein another embodiment of my adjustable door brace construction. Elements in this embodiment similar to those of the embodiment of Figs. 2-4 have been designated by the same numbers. In Fig. 5 only the adjustable mounting means for one end of the brace 17 have been shown, but it will be understood that the corresponding end of the brace 18 is mounted in exactly the same manner. It will also be understood that the other ends of the

braces

17 and 18 are held by suitable rigid means attached to gussets or other members mounted at the opposite corners of the door. For example, they may be mounted by the means shown in Fig. 3.

In the arrangement of Fig. 5, the hooked end 20 of the brace 17 is held by means of a bracket 40. This bracket 4t) includes a principal body portion 41 and two

oppositely extending legs

42 and 43. The one leg 42 extends outwardly toward the inner face of the door 2 and at its outer end engages a tlange 44 of a corner gusset 45 of the door shell 4. The other leg 43 of the bracket extends inwardly into the door and near its inner` end is provided with an aperture 46 `through which the hooked end 20 of the brace 17 is fitted. The leg 43 of the bracket thereby serves to mount the end of the brace. As shown, the bracket spaces the brace 17 inwardly from the inner face of the door far enough to allow for a deep recess 9 to be formed in the door liner 8.

It is by means of the bracket 40 that the brace 17 is adjusted, the bracket being movable to effect the` adjustment. For both mounting and moving the bracket 40 there is provided a bolt or fastening means 47.` This bolt 47 extends through an aperture 48 in the gusset 45 and is threaded into a dimple 49 provided in the body portion 41 of the bracket. The head 50 of the bolt engages a rounded surface provided by a raised boss 51 formed on the upper side of the gusset 45. In other words, the head of the nut and the gusset engage through rounded surface means.

The engagement between the bolt head S0 and the rounded boss 51 results in adjustment of the brace 17 as the bolt 47 is tightened. As the bolt is tightened, it pulls the body portion 41 of the bracket `toward the gusset. This results in the bolt ltilting on the rounded surface of the boss and that in turn causes the bracket to pivot as a whole around the end of its leg 42. This action is shown by the dotted lines in Fig. 5. The pivoting of the bracket 40 is to the right as viewed in Fig. 5 so that it pulls on the hooked end 20 of the brace 17 and places it under tension, As the tightening of the bolt is continued, this tension is increased, and by sufciently tightening the bolt the bracket and the end of the brace .may be moved far enough to adjust the plane` of the door to the desired position. Y

In the embodiment of Fig. 5, as in the embodiment of Figs. 2-4, the cross braces may be adjusted after the door is completely assembled. In this embodiment, the head 50 of the bolt 49 lies adjacent the door liner 8. In order that the bolt may be turned after the door s completely assembled, means are provided whereby a tool may be inserted through the liner 8. This means comprises the removable cap or button 37 which is positioned over an aperture 3S in the liner. This aperture 38 directly overlies the head 50 of the bolt so that when the cap 37 is removed the tool may be engaged with the bolt for tightening it.

Thus, by my invention I have provided a door brace construction which permits the use of a door liner having a deep recess, but yet which is readily adjustable after the door is completely assembled. This cross brace construction consists of only a few parts which may be simple `and easily fabricated. Further, its assembly within the door is a quick and uncomplicated process. As a result the cross brace'construction is relatively inexpensive, which of course is a considerable advantage in a high production item such as refrigerators.

While in accordance with the patent statutes I have described what at present are considered to be the preferred embodiments of my invention it will be obvious to those skilled in the art that various changes and modilications may be made therein without departing from my invention, and I, therefore, aim in the appended claims to cover all such claims and modifications which fall within the true spirit and scope of my invention.
