United States Patent T 3,555,733 COMBINED HINGE AND GLASS DOOR UNIT William J. Horgan, Jr., Pittsburgh, Pa., assignor to Blumcraft of Pittsburgh, Pittsburgh, Pa., 21 firm of Pennsylvania Filed Apr. 30, 1969, Ser. No. 820,541 Int. Cl. Ed 7/08 US. Cl. 49-388 14 Claims ABSTRACT OF THE DISCLOSURE A hinge for use with glass doors having solid frames includes a hinge element for a pivotal hinge of the type used where the door is pivoted at top and bottom, which element is adjustable in two directions to provide means for correct-ing misalignment in hanging the door.
BACKGROUND OF THE INVENTION This invention relates to hinges and in particular to a novel hinge element for use with frame elements on glass doors.
In the prior art, glass doors of the type used in commerical establishments having a metal frame including a top and bottom shoe were hung by means of pivot-type hinges connected to the top and bottom shoes. These hinges included pintles mounted in the doorway and in the floor which were engaged by elements mounted in the shoes. The bottom shoes were normally provided with a thin walled channel extending substantially the full length of the shoe and opening downwardly. Within this channel a long arm extended from the pintle mounted in the floor to a point substanially removed therefrom within the channel. At this point the arm was engaged by adjustable means which coacted with the side walls of the channel to pivot and position the arm. Such arms were normally on the order of 7 to inches in length for leverage and load transmission reasons.
As shown in my co-pending application Ser. No. 707,- 055, filed Feb. 21, 1968, I have invented a new door consisting of a plurality of load carrying frame members and an integral glass member forming a unitary structure. The frame members are solid along the periphhery or base portions thereof, and accordingly, the prior art hinge elements of the type described would not be adaptable or acceptable for use with my new door construction.
SUMMARY OF THE INVENTION The present invention provides a means for pivotally mounting a glass door which includes sol-id frame members and for adjusting the position of the door with respect to the floor mounted pintle. It comprises means externally engaging the frame and bearing against it, Which means are adjustable laterally with respect thereto, means for engaging the floor mounted pintle and means for engaging said last mentioned means and relatively rotatable thereabout, including adjustable means for fixedly engaging said first mentioned movement therebetween and being capable of locking both of said means in fixed positions relative to one another.
Accordingly, it is another object of this invention to provide a novel hinge element which is adjustable to compensate for misalignment, and adaptable for use with existing hinge elements.
It is a further element to provide such a hinge element which is particularly adaptable to pivotal hinges of the type used on swinging doors having solid frame members.
These and other objects of the invention will become apparent from the following description with reference to the drawings.

DESCRIPTION OF PREFERRED EMBODIMENTS Although specific forms of the invention have been selected for illustration in the drawings, and the following description is drawn in specific terms for purpose of describing these forms of the invention, this description is not intended to limit the scope of the invention which is defined in the appended claims.
Referring to the figures, FIG. 1 shows a door designated generally 10 which includes a glass panel 11 and a metal frame including a top shoe 12 and a bottom shoe 14. The door is supported by pivot type hinges attached to the top and bottom shoes and the supporting frame and door structure.
The upper hinge '16 is more clearly shown in FIGS. 2
and 3 and comprises a generally box-like rectangular housing 18 which has a peripheral groove about three sides so that it fits snuggly into a rectangular notch in the shoe 12, overlapping and engaging the sides of the shoe with its supporting flanges 20. The housing 18 is securely fastened to the shoe 12 as by means of a machine screw 22 which passes through the base of the housing and is threaded into the shoe 12 as shown in FIG. 3.
The housing 18 contains a central bore which has press fitted therein a bushing 24 forming a bearing for the pintle 26. The pintle is normally retained in the frame surrounding the door by any suitable means well known in the art and provides the means whereby the upper portion of the door is retained and pivoted.
The housing and bearing remain fixedly engaged to the pintle 26 while the door itself is movable with respect to the housing. To accommodate this movement, the slot through which the screw 22 passes in the housing 18 is elongated.
If it is necessary to shift the door 10, FIG. 1, to the left or right shims 28 and 29 which are used to space the housing 18 in the slot in the shoe of the door, can be rearranged to provide more shims on one side of the housing 18 than the other.
The hinge just described provides for some lateral adjustment, but the principal source of adjustment in accordance with this invention is provided at the base of the door. The bottom shoe 14 has attached to it a hinge designated generally 30, FIG. 1, which supports the door and provides a means about which it pivots. This hinge is shown in more detail in FIGS. 2, 4, 5 and 6. One element of the hinge comprises a floor mounted pintle 32, FIG. 2 which is a standard item Well known in the art. This pintle is mounted to a plate fixed in the floor and can be rotated with the door. The pintle is generally rectangular in cross section as shown in FIG. 6 and the sides are beveled inwardly toward the upper end to 'accept the mating hinge member. My invention lies in the remaining elements of the hinge in combination with my new door, as I shall nOW describe in more detail.
The elements of the hinge which are attached to the door include a housing 34 which has a peripherial slot about three sides thereof so that the side walls form extending flanges 36 (approximately /2 of an inch thick) to engage and overlap the sides of the bottom shoe 14. The slot in the embodiment illustrated in the drawings is on the order of A of an inch wide, as is the shoe 14. Thus the housing 34 is designed to fit snuggly against the sides of the shoes 14, embracing it in a sliding fit. The housing is seated in the notch in the shoe 14 so that its bottom surface is in the same plane as the bottom of the shoe 14.
The shoe 14 is solid around the periphery or base portion thereof and, as described in my co-pending application, has a channel means formed above the base on the inner side thereof for reception of the glass panel 11. The frame of which the shoe is part is attached to and coacts with the panel 11 so that the whole forms a unitary structure, and accordingly, a load imparted to the face of the glass panel 11 in order to open it will be distributed through frame member 14. As previously stated, prior art frame members were hollow at the base and had only thin support walls forming a channel. It was therefore necessary to place the force reaction point for the pivot arm as far removed on as possible from the pivot point in order to get the greatest mechanical advantage and prevent the shoe from buckling. The solid frame construction in accordance with my invention makes possible the use of a compact hinge element. Thus by virtue of the overlapping flanges and snug fit which the housing 34 has with the shoe 14, the forces are concentrated and distributed to the shoe in the immediate area of the pintle.
The inner sides 40 and 42 of the housing formed by the peripheral groove are spaced from the side walls 44, 46 of the notch in the shoe 14 to provide a clearance for lateral adjustment. Such adjustment is made by the set screws 48, 50 which are threaded into holes in the side walls 40 and 42. The set screws are withdrawn to make up the space so, that the housing then fits snuggly with the heads of the set screws bearing against the walls 44 and 46 of the notch in the shoe 14. By extending the screw relatively more than the other the housing can be shifted laterally within the notch. To accommodate this shifting, a slotted opening is provided in the upper wall 52 of the housing through which a suitable fastening means, such as machine screw 54, passes into a threaded hole in the shoe 14. The head of the machine screw engages the sloping side walls of the opening to retain the housing in the notch.
The housing has a blind bore 60, FIG. 4 which accepts a cap element 62. The cap is substantially cylindrical and the top of the cap rests against the blind end of the bore while the sides of the cap rotatably engage the sides of the bore. The cap has a centrally located blind hole disposed axially therein and having slopping sides to accommodate the upper end of the pintle 32 as shown in FIG. 4.
The cap 62 has an ear 64 extending from one side into a clearance slot 66 which extends from one side of the bore 60 in the housing. On either side of the housing, set screws 70, 72 are threaded through the /2 inch thick Walls to engage the ear 64 as shown in FIG. 6. By advancing one set screw, relatively more than the other, the housing can be rotated about the cap 62. By tightening both set screws against the ear 64, the housing can be fixed in position with respect to the cap.
Thus, my invention works by providing a means for engaging a standard pintle and rotating therewith, which means can be fixedly connected to a solid shoe to pivot a door, said means providing for the relative adjustment of said door with respect to said pintle. In operation, the housing 34 is placed in the notch in the shoe 14 in its correct lateral position and then the door with the housing and cap is placed over the pintle 32. If the door does not hang correctly or close properly against the jam rotational adjustment is possible by means of backing off one of the set screws and advancing the other. As far as lateral ad- 4 justment is concerned this can be taken care of prior to the time the housing is inserted into the notch in the shoe 14 by simply measuring the distance from the center of the pintle and adjusting the set screws 48 and 50 accordingly.
