Dec. 6, 1955 J. D. CARR ADJUSTABLE ATTACHMENT FOR FOLDING DOORS Filed Aug. 12, 1952 INVENTOR.

.tachment that will consist of a United States Patent ADJUSTABLE ATTACHMENT FOR FOLDING DOORS Application August 12, 1952, Serial No. 303,989 1 Claim. (Cl. 160-84) My invention relates to an adjustable attachment for folding doors and the objects thereof are to make an atfew parts and be economical to manufacture.

A further object of the invention is to provide an adjustable attachment, wherein folding door structures can be readily adjusted to fit any space, any irregularities in heights at opposite ends, thus providing a means wherein folding door structures as a whole can be made into package units, thereby saving same time providing a more durable structure to meet various conditions.

A still further object of the invention is to provide an attachment for folding doors wherein the hinges are adjustably secured to the supports and are held and maintained in this adjusted position to meet any and all requirements relative to size or irregularities in the various spaces where folding doors are to be used.

A still further object of the invention is to provide an inexpensive adjustable attachment, wherein the hinges may be readily adjustable vertically in relation to the frames, and means for supporting these hinges throughout their length by adjustable members so as to permit the folding door structures to be ready at all times, to be mounted in any space regardless of height or irregularity.

With these and other objects in view, the invention consists of certain novel features, combination and arrangement of parts as will be hereinafter more fully described, pointed out in the accompanying drawing, and claimed.

In the drawing,

Figure 1 is a perspective view, partly broken away, illustrating my adjustable attachment for folding doors;

Figure 2 is a plan view, illustrating the attachment and the method of adjusting the same;

Figure 3 is a fragmentary, plan view, illustrating the adjustability of the supporting hinges; and

Figure 4 is a fragmentary, perspective view, illustrating the entire unit assembled and showing its adjustability relative to the frame and supporting hinges.

In the present invention it is the aim of the inventor to provide an adjustable attachment, not only for folding doors but for drapes, curtains or any equivalent structures, wherein various heights may be compensated for by the adjustability of the hinges to the frame for any such structures heretofore named.

It is a Well known fact that in the present use of folding doors, wherein large areas may be divided into smaller spaces or areas by the use of the doors, it necessitates the use of supports or aframe having hinged thereto foldable hinges, and these hinges are adjustably supported by adjusting rods. Thus it can be seen, that regardless of the irregularities in the spaces to be closed, it can be readily compensated for. In the present type it is impossible, unless the measurements are absolutely accurate, to use such structures. If the measurements be wrong, the whole unit must be sent back and be re-cut, and it is to overcome this serious objection and to make a package unit time and expense, and at the of folding doors, that the inventor has produced the structure now being described. In other words, by virtue of the adjustability of the hinges to the frame and by supporting the hinges on adjustable rods, measurements are secondary and the structure can be made into a package unit and sold, and any areas or spaces can be divided as found necessary.

Referring to the drawing, the numeral 5 indicates a track having the roller structure 6 mounted for movement therein. The roller structure 6 is supported by the roller rod 7 and attached to this rod and depending therefrom are the pivotally mounted hinges 8. The hinges are normally secured to a fixed frame structure 9, and the structure just described is common practice, and the present inventor is not claiming this as his invention, but it is to the frame 9 and hinges 8 that his invention does apply.

It is the aim of the inventor to provide the frame 9 with struck out tabs 10, and the extreme terminal hinge 8 is provided With cooperating tabs 11, and these tabs 11 coact with the tabs 10 and have passed therethrough a pin 12 which adjustably secures the hinge member 3 to the frame 9.

Now if it is necessary to minutely raise or lower the hinge structure 8, it is only necessary to withdraw the pin 12, fit the corresponding tabs 14 and 11 together at the proper height and refit the pin 12. Thus, you have your hinges adjustably secured to the frame for any height in a quick and efi'icient manner.

It is to be understood that this invention can be for double doors, single doors or for any structures wherein a folding door is necessary.

Now to further support the hinges throughout the area of the material that is fixed thereto, there are provided tubular rods 13 and these rods form a part of the hinges 8, and arranged within these tubular rods 13 are the supporting rods 14, provided with spaced grooves 15 to receive therein a fastening pin 16. Now the purpose of the rods 14 with their grooves 15 telescopically mounted in the tubular members 13 is to permit the rods to be adjusted therein and held in the adjusted position by the pin 16. Thus any irregularities in height can also be compensated for and the folding door made to fit any areas necessary without further measuring and cutting the structure to fit such measurements.

It is to be understood that various changes may be made to the structure disclosed without departing from the spirit and scope of the invention as described and claimed.

Having thus described my invention, what I claim as new is:

A hinge structure of the class described comprising an upper hinge member and a lower hinge member arranged in suitable spaced relationship below the upper hinge member, each hinge member including a terminal plate and a series of hinge plates arranged end to end with respect to each other and with respect to the terminal plate, means for pivotally connecting one end of both of said terminal plates to a single fixed support, means for pivotally connecting the other end of the upper terminal plate to an adjacent end of the first of the series of upper hinge plates, means for pivotally connecting the adjacent ends of said upper series of hinge plates together, means for pivotally connecting the other end of the lower terminal plate to the adjacent end of the first of the series of lower hinge plates, means for pivotally connecting the adjacent ends of said lower series of hinge plates together, said pivot means for the upper series of hinge plates comprising tubular rods depending from the upper hinge member and terminating at a distance above the lower hinge member, said pivot means for the lower hinge member comprising rods extending upwardly from the lower hinge member and mounted within the downwardly extending tubular pivot rods of the upper hinge member, whereby said hinge members are movable vertically toward and away from each other, means for adjustably positioning the terminal plates of said. hinge members on their fixed support, and means for securing the lower pivot rods in fixed position with respect to said tubular rods of the upper hinge member, said means for pivotally connecting the upper and lower hinge plates together being arranged whereby said upper and lower hinge members are extensible as a unit outwardly from 1 the terminal plates and collapsible as a unit inwardly toward said terminal plates.-
