Application May 13, 1957, Serial No. 658,629

17 Claims. (Cl. 160209) This invention relates to hinges and roller supports for slidably mounted doors and particularly desirable for doors of the upwardly acting type including a plurality of horizontally hinged sections and associated with tracks having sections rearwardly inclined which are relative to the door frame. The main objects of this invention are:

First, to provide a combined hinge and roller support for sectional doors of the type including tracks having rearwardly inclined upright portions which provide for variably positioning the track engaging rollers to insure that the door will close against the door frame.

Second, to provide a combined hinge and roller support in which the roller support may be variably positioned relative to the pintle of the hinge, the structure comprising only five parts including the pintle one and in which the parts other than the pintle may be formed of sheet stock.

Third, to provide a combined hinge and pintle support having these advantages which may be readily installed to meet the particular requirements without the aid of tools other than required for attaching the hinge to the hingedly connected parts.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. 13 is a fragmentary inside view of the embodiment of my invention shown in Fig. 12.

In the accompanying drawings 1 represents a door frame and 2 a sill. The door comprises a plurality of horizontally articulated sections including a top section 3, bottom section 4 and intermediate sections 5. The track comprises rearwardly inclined upright sections 9 and horizontal sections it connected by intermediate curved sections 8. These parts are old in the art. My present invention relates primarily to the combined hinges and track engaging roller supports and the brackets for supporting the track engaging rollers at the upper edge of the top section.

One of the main objects of my invention is to provide a combined hinge and roller spindle support which may be readily adjusted to compensate for the inclination of the track so that the door is held against the door jamb when in closed position. The applicant has pending applications Serial No. 643,862, filed March 4, 1957, now Patent No. 2,877,843, issued March 17, 1959, and Serial No. 613,909, filed October 4, 1956, which disclose structure designed for the same general purpose. The structure of this application, however, has various advantages over the structures disclosed in the said pending applications. In the embodiment of the invention illustrated the combined hinge and roller support comprises the

leaf hinge members

11 and 12 having coacting

hinge knuckles

13 and 14 respectively connected by the pintle 15. The hinge knuckles 13 are somewhat elongated as is illustrated in Figs. 3 and 4 permitting some lateral movement of one section of the door relative to the adjacent hinged section to which it is hinged. The

hinge members

11 and 12 are provided with holes 16 adapted to receive attaching bolts 17. The track engaging rollers 18 are provided with spindles 19. The rollers are preferably rotatably mounted on their spindles, ball bearings being commonly used, but as that detail forms no part of this invention it is not illustrated except as indicated at 20 in Fig. 10.

In order to seat the door against the jamb and to provide clearance on the initial opening movement of the door, the vertical or upright portions 9 of the track are inclined rearwardly or away from the door frame. This necessitates that the roller spindles or shafts be variably spaced relative to the plane of the door. In the embodiment of my invention illustrated this is accomplished by means of the inwardly facing channel shaped holder memher or bracket 21 having

parallel side walls

22 and 23 connected by the bight 24. The side walls of the holder member have outturned

flanges

25 and 26 respectively. The flange 25 is extended to provide pintle engaging ears 27 disposed at the outer side of the hinge knuckles and pivotally engaging the pintle 15. This pivotal engagement is primarily for the purpose of assembling other parts and to provide an effective support. The side wall member '23 is provided with a downturned flange 231 on its inner edge which is lapped upon the hinge member 12 and secured thereto by one of the attaching bolts 17.

The bight 24 of the holder member or bracket is. provided with a slot 28 and the hinge member 12 has a slot 29 therein aligned with the slot 28. These slots receive the projecting tongues 30 on the inner and outer edges of the spindle socket member 31 when it is arranged within the bracket or holder member 21 in supported relation to the side wall 23 thereof, see Fig. 3, in which position the end edges of the member '21 are in supported en- 'gagement with the hinge member and the bight of the bracket member. The member 31 has a curved offset 32 which coacts with the wall of the holder member 21 against which it is disposed to provide a spindle socket. The socket element 32 is in supported engagement with the wall 22 of the member 2 1 so that the loads ofstr'esses upon the'ro ller spindle 19 are effectively sustained.

The socket member 31 is reversible in the holder thus enabling the supporting of the spindle in two positions.

the roller spindle in eight positions relative to the door.

The hinges and the spindle holders or brackets are'uniform and may be preassembled. If, for example, the door comprises nine sections as is illustrated, only four sets of the socket members 31 are required for the eight hinges and they may be assembled with the hinges and In practice'the socket members 31 are modifiedby varyhighly practical embodiment thereof.

supporting brackets on the job before the fastenings 17 are secured. To assemble, the holder members are swung on the pintles which permits the proper positioning of the proper socket member therein. The holder members or brackets are then swung to position shown in Fig. 3

and the fastener 17 inserted. This simplifies both production and installation of the fasteners.

While one of these hinges could be secured to the top doorsection in non-hinging relation thereto, I preferably provide brackets 34 of inwardly facing channel section having flanges 35 on the sidewalls thereof which are fixedly secured to the top section of the door adjacent the upper edge thereof as by means of the screws 36.

The spindle socket member 37 associated with this bracket 34 is provided with flanges 38 embracing the side edges of the bracket member. These flanges terminate in cars 39 through which the ends of the tubular socket 40 is disposed, the ends of the tubular socket being upset at'41 to retain the same and also the socket member constitutes a reinforcing means and a tie for the flanges of the socket member. The ears 39 overlap the side edges of the holder member so that when the tubular spindle socket is upset thereon the parts. are capable of withstanding heavy stresses although formed of relatively light stock. The tubular socket 40 is a sliding fit between the 1 when the door is fully closed. This" adjustment adds substantial variations in the inclination of the track and such as might occur in installing. The parts may be adjusted after the track is erected to be sure'that the door seats against the jamb when in fully closed position. The spindle'46 of the bottom roller is carried by brackets'45 secured to the bottom section 4 of the door so that the spindle is disposed closely adjacent to the sill when the door is fully closed. In Fig. 4 I illustrate theleaves of the hinge without the'spindle holder and they maybe used where it is desirable to provide the doors withintennediate hinges.

It will be noted that when the door is in fully closed position as illustrated in Figs. 1 and 2,'the track 'engag ing rollers at the upper edge of the top door section are 111 engagement with the curved portion 8. of the track, the purpose of that being to swing the upper edge of the door against the door frame. Quite commonly the section 10 of the track is straight.

The transverse elongating of the knuckles 13 permits tilting movement'of the section 3 relative to the adjacent door section 5, as is illustrated in Fig. 11, and this angular or tilting movement does'not subject the hinge or other parts to undue strain. It also relieves the hinges of strain as they travel around the curved part 8 of the track.

In Figs. 12 and 13 I have illustrated an embodiment of my invention in a door structure in which the door sections are formed of sheet metal and comprise outer and inner panels 50 and '51 respectively, the outer panel 50 being conformed to provide top and-bottom rails 52'and 53 respectively to which the inner'panel 51 is secured at 54, desirably by spot Welding. The inner panels have integral knuckles '55 on their upper edges and '56 on their lower edges, the knuckles '56 being desirably elongated in the plane parallel to the plane of the door section, these elongated knuckles corresponding to the knuckles 13 of the embodiment shown in Figs. 1 to 11 inclusive.

The supportsfor the spindles 19 of the track engaging "rollers IS-are thesani'eas when adjapted'to wood door sections except that'the inner'pa'n'els are provided with threaded studs 57 'adaptedto'receive the retaining nuts 53.

I have illustrated and described "my invention ha I have not attempted to illustrate or describe other adaptations "or embodiments whichI contemplatefasd believe this "dis- *elosurewill'enable those skilled in the 'art to embody or adapt my invention'as may be desired.
