HINGE 3 Sheets-Sheet 3 Filed Jan. 2, 1958 United States Patent 3,008,175 HINGE Henry J. Biedinger and Carl J. Kuckhofi, Syracuse, N.Y.,
assignors to Syracuse Stamping Company, Inc., Syracuse, N.Y., a corporation of New York Filed Jan. 2, 1958, Ser. No. 706,615 2 Claims. (Cl. 16128) This invention relates to hinges and more particularly to a pin-less sheet metal hinge adapted for sectional garage doors and the like.
In overhead doors of the multiple horizontally extending sectional panel type, for example, as shown in Johnson 1,820,195, the adjacent sections of the door are hinged together at their ends, and if a wide door, preferably intermediate thereof, so that the central sections when angularly disposed may brace one another. Such hinges as are located at the ends, either at their pivot, or by means of a separate bearing structure in one of the hinge members carries a stub shaft and roller to cooperate with track ways to guide the door, which track ways are usually inclined slightly in respect to the vertical plane of the door frame whereby to provide contact of the door with the door frame, when in closed position only.
The present invention is directed to a hinge construction composed of two members only, formed of sheet metal and adapted to provide a rugged hinged connection between adjacent door panels or the like. The invention is further directed to a hinge construction comprising a member having a cylindrically rolled-up integral tubular portion adapted to journal within cylindrical extrusions of the spaced side flanges of the companion member, the cylindrically rolled-up tubular member being so disposed within the extrusions as to tend to contract the tubular portion when under load. Further, the invention has to do with the formation of a sheet metal blank of a shape to be readily thrust into a roll-up die for economical forming of the tubular pivot portion of the hinge member.
The above and other novel features of the invention will appear more fully hereinafter from the following detailed description when taken in conjunction with the accompanying drawings. It is expressly understood that the drawings are employed for purposes of illustration only and are not designed as a definition of the limits of the invention, reference being had for this purpose to the appended claims.
Referring to the drawings wherein like reference characters indicate like parts:
FIGURE 1 is a side elevational view of the hinge;
FIGURE 2 is a plan view of the hinge taken partly in section along the line 22 of FIGURE 1;
FIGURE 3 is a view of the blank from tion of the hinge is formed;
FIGURE 4 is a side elevation of the blank of FIG- URE 3 after rolling up the tubular portion to form one hinge member;
FIGURE 5 is a plan view of the hinge member of FIG- URE 4;
FIGURE 6 is a perspective view of the hinge member of FIGURE 4;
FIGURE 7 is a plan view of the blank employed to form the companion hinge member;
FIGURE 8 is a plan view of the hinge member;
FIGURE 9 is an end elevation of the hinge member;
FIGURE 10 is a schematic sectional view of the rollup die; and
FIGURE 11 is a perspective view of a hinge modified to provide a roller support spaced from the hinge axis.
In FIGURES 1 and 2, the hinge parts 20 and 22 are shown pivoted together as at 24. The hinge member 20 which one poris formed from a blank of sheet steel or other suitable material as at 26 (FIGURE 3) such blank being shaped to form a tongue 28, transverse drive shoulders 30 and 32, which may also serve as mounting guides, and a portion 34 adapted to be rolled up into an integral tubular portion, such portion being extended on either side, as at 36 and 38, the extension portions being offset as at 40, for reasons as will be made to appear. The portion of the blank indicated by the bracket R is adapted to be rolled up to form a true cylinder.
As shown in FIGURES 4 and 5, the extended portions 36 and 38 are rolled up and the ends 42 and 44 have been brought around into abutment with the shoulders 46 and 48, so that the portions 36 and 38 form true complete cylinders. The edge 58 has been brought around to abut the surface 52 of the blank as shown in FIGURES 4 and 6. The blank may be bent as at 54 to suitably elevate the axis of the rolled up portion from the plane of the tongue.
The other member is formed from a blank 60 as shown in FIGURE 7, such blank being of generally triangular shape, and being adapted when formed on the lines 62 and 64 to form side flanges 66 and 68 and a tongue portion 67. The metal adjacent the apertures 70 and 72 is extruded outwardly to form integral flanged internal hearing sleeves 74 and 76 for receiving the bearing ends 78 and 80 of the member 20. Prior to forming the flanges 66 and 68 into parallel relation, and while disposed at angles of about to the plane of the tongue portion 82, as indicated in dotted lines in FIGURE 9, the bearing ends 78 and of the member 20 are placed in straddling relation to the side flanges 66 and 68 and their openings, after which they are formed to the parallel relation shown to embrace the tubular bearing ends of the member 20 as shown in FIGURE 2.
In forming the rolled up end of the member 20, the shoulders 30 and 32 act as driving shoulders for forcing the blank end into a roll up die such as indicated in FIGURE 10, wherein the separable die members and 92, and removable core 94, provide a suitable cavity. Force is applied against the shoulders 30, 32, in the direction indicated by arrow F, to effect the roll up operation. Such shoulders may later act as guides for properly locating the hinge on a door panel.
In practice the hollow tubular end of the member 20 may be used to receive a stub shaft for a door guide roller in the manner indicated in Johnson Patents 1,936,237 and 1,820,195 and as shown in FIGURE 11. Where it is desired to locate such as stub shaft at greater distances from the plane of the hinge tongue 67, the side flanges 167 and 169 of the member 23 may be increased in height as in FIGURE 11, and extruded apertures as at 88 provided in such side flange, to receive a rolled up tubular sleeve 89 as shown, a stub shaft 81 and roller 83 may be inserted in the sleeve 89. The height of the sleeve above the plane of the hinge tongues may be varied by forming the extrusions 88, at such height as desired.
It will appear that the hinge members thus formed are both economical of manufacture, and render a separate pintle unnecessary. Further, by reason of the rolled up portions forming bearings within the extruded side flange bearings, any loading upon the hinge tends to close up the rolled up portions causing the ends 42 and 44 to abut the shoulders 46 and 48 and thereby be placed under circumferential compression to resist deformations. Where rolled up hinge portions have heretofore been employed, the rolled up portion has generally been located external of the pintle, with the result that loading tends to load the sleeve in tension, and tends to unro'll rather than roll up the rolled sleeve portion. The construction thus permits the use of thinner stock, which the strength of the load sustaining portions 78 and 8E! of the rolled up portions. In addition, such recess 29 -facilitates the actual roll up operation, by minimizing the width of material actually subject to deformation or roll up. In a similar fashion the companion member 22 may be recessed as at 65, to economize on material required, without the loss of strength. The blanks of both parts may be stamped from sheet material, and the recesses 29 and 65 may be complemental to the shape of the tongues 23 and 67, so that a single cut forms parts of both blanks simultaneously, resulting in economy.
The drive shoulders, 30, 32 are cut and the apertures 27 pierced in the initial blanking operations, and the shoulders assure that during the roll-up operation the axis of the roll-up will be formed with exact location in respect to the apertures, so that each finished hinge member will conform exactly with every other member. Thus, by reason of the drive shoulders, 30, 32, the exact spacing between the axis of the rolled-up portion and the aperture centers are maintained, and the apertures may therefore be pierced at the same time the blank is cut and the shoulders formed.
Although a single embodiment of the invention has been illustrated and described, it is to be understood that the invention is not limited thereto. As various changes in the construction and arrangement may be made without departing from the spirit of the invention, as will be apparent to those skilled in the art, reference will be had to the appended claims for a definition of the limits of the invention.
What is claimed is:
1. In a hinge, a one piece sheet metal hinge member comprising a tongue and parallel spaced side flanges, each of said side flanges having an outward extrusion forming an integral internal cylindrical bearing sleeve, and a complemental one piece sheet metal hinge member comprising a tongue as one end and an integral rolled up portion of greater width than the tongue at the other end, and providing external bearing portions extending laterally beyond either side of the tongue, and said bearing portions being pivotally disposed in said bearing sleeves, the external bearing portions extending laterally beyond the width of the tongue being formed from elongated rectangular areas of the complemental member offset lengthwise thereof in a direction away from the tongue end to form projecting ends at the other end and said areas forming complete cylindrical sections, with edges abutting.
