6 Claims.

This invention relates to door mountings and more particularly to mountings of the type for connecting a series of door sections as a unit so that they may be mounted and operated all together. 7

Up to the present time it has been the practice to connect door sections as a unit by employing trusses or the like which are cut to correspond with the size of the door unit to be made, the trusses being orificed at certain prescribed points so that they may be bolted to the door sections to hold them firmly.

The disadvantages of this type of construction are that such trusses have to be made to order after information is obtained as to what size of door unit is to be constructed and as a result it is impossible in many cases to make up standard trusses that can be kept in stock and used under most circumstances. In View of this more time is necessary to produce the door unit while, on the other hand, it is not possible to construct it as economically for the reason that trusses of this nature cannot then be made in slack time and stored for future use. These disadvantages are overcome by the present invention through which door mounting construction is provided that can be adapted within reasonable limits to various sized units that are to be constructed.

According to the invention, a flanged truss is provided which is designed to extend over a plurality of door sections to unite them as a unit, the truss being constructed so that it is not necessary to form it with bolt holes at specified points, by including a series of base plates which are designed to be disposed between the truss and the door sections and a series of clamping plates designed to overlie the flanges of the truss above the base plates with bolts designed to pass through the door sections, through the base plates and on each sideof the truss clear of its flanges to engage with the clamping plates which overlap the truss flanges and lock the truss on the unit. Associated with such truss are fittings or side plates designed to be fastened to the opposed side edges of the unit to form means of slidably connecting the unit in the door frame where it is to be mounted, the fitting including a connecting member cooperating with the truss and designed to move axially in respect thereto so as to locate the fittings at their proper points regardless as to whether the ends of the truss are spaced inwardly from the side edges of the unit.

to the following detailed specification taken in conjunction with the accompanying drawing.

Fig. 6 is a fragmentary perspective detail of the truss and perspective of the mounting plate -to illustrate their general construction.

Referring to the drawing, A indicates a door unit designed to receive the door mounting means according to the present invention. This door unit is made up of a plurality of door sections, four being illustrated in the drawing and numbered I0, ll, l2 and I3. The door sections are designed to be connected as a unit by means of the transversely extending trusses B, the trusses preferably taking the V-channel form as indicated particularly in Fig. 6 and formed with laterally projecting flanges I 4. As illustrated, the flanges are not orificed to form bolt holes as would ordinarily be the case.

According to the invention the trusses are mounted on the door sections by means of a base plate l5 which takes the form of a central body 16 of rib-like construction which extends above the plane of the projecting side aprons H, the rib-like body i6 being of a cross section that will fit up into the channel l8 of the truss as clearly shown in Fig. 5. Thus the flanges l4 rest upon the side aprons I! of the base plate on each side of the rib-like body I6. The rib-like member or body It functions generally as a reinforcing member for the truss and will prevent the side walls of the truss from shifting inwardly under any circumstances.

The base plates are designed to be mounted on The invention will be understood by reference the door sections at required points and this is accomplished by bolting them on the door sections by means of the bolts it, the bolts being designed to project through the door sections and through the aprons of the base plates which, as shown, are orificed as at 2B. The truss is then secured On the base plates by means of clamping plates 29 which overlap the flanges l of the truss. The bolts projecting through the base plates pass on each side of the truss and clear of the flanges, being designed to project through the clamping plates so that when the bolts are tightened the clamping plates firmly hold the truss on the base plates, the whole being secured to the door sections by means of the bolts. This is clearly illustrated in Fig. 2.

As illustrated in Fig. 1, the base plates are preferably positioned to overlap the line of juncture between each door section with two bolts passing through one door section and two bolts passing through the adjoining door section. Consequently a very firm bracing of the unit results. Of course, the base plates may be made larger if so desired and more than four bolts might be employed to secure it, whereas it would also be understood that the structure of the base plate might be smaller and of such character as only to require the use of two bolts.

The end portions of the truss may be secured by a structure of this latter character if desired but, on the other hand, it is preferable to orifice the flanges adjacent their ends and to pass a bolt directly through the flanges and door section in question at this point.

It will be clear from the preceding description that a very simple and efiicient manner of con- 1:

necting door sections in a unit is produced. It is obvious, of course, that within certain limits it is not necessary to have trusses constructed to conform exactly with the specification of the door sections as the securing means can be positioned at any point along the length of the truss that is desired. Thus by employing a simple truss of a standard length 'a series of door sections may be secured together as units regardless of the fact that one series might employ door sections of a different size to others.

To complete the structure and adapt it for use as a swinging garage door unit or the like, side plate fixtures 22 are designed to be mounted at the side edges of the completed unit. This side plate fixture may take the form of a chane nelled member, as shown, carrying a pintle or shaft 23 which carries a roller 2% projecting la erally therefrom and beyond the marginal edge of the unit. As shown in Fig. 3, this roller is designed to project into a channel guide 25 which is positioned along the length of the side of the door frame. In this particular instance the door is suspended from the overhead channel suspension members 2b which receive the suspending straps 21 of the door unit so that when the latter is raised the suspension straps 2? and associated parts will slide longitudinally in the chane nel suspension members 25, while the side rollers 24 will ride vertically upward in the channels 25. The side plate fittings 22 are connected with the truss by means of laterally projecting shanks 29 clearly shown in Fig. 3 which are designed to project into suitable sleeve-like guides Or bushing 28 which are disposed within the channel i8 sliding connection is effected between the shanks and the members 28. In other words, therefore, a firm and substantial connection between the shanks and truss is effected.

It will be apparent from consideration of this structure that the side plate fittings and attached construction completes the door unit for mounting and cooperates with the truss to provide an extremely firm mounting as it in effect constitutes a final anchoring member. Moreover, it will be clear from a consideration of Fig. 3 that whetherv the ends of the truss terminate at a distance spaced inwardly from the side edges of the unit or whether they are spaced closer to the side edges or slightly farther away therefrom does not make any material difference, since the shanks 29 may be slid in the guides 23 until the fitting plate 22 is disposed at the marginal side edge of the unit.

It is clear in the foregoing, therefore, that I have provided a door mounting structure which is both simple and efficient in construction and avoids the necessity of manufacturing the bracing trusses to any given length to suit particular door units that may be required at one time.

What I claim as my invention is:

1. Door mountings comprising a flanged truss designed to extend over a plurality of door sections to unite them as a unit, a series of base plates disposed between the truss and the door sections spaced along the length of the latter and straddling each joint therebetween, bolts extending through the door sections, through said base plates and on each side of said truss and clear of its flanges, and clamping plates overlapping said flanges and engaged by said bolts for securing said door sections to the truss.

2. Door mountings as claimed in claim 1, in which the truss is of channel form and is provided with a guide member disposed within the channel adjacent each end of the truss, a fitting for each side edge of the door having a laterally projecting shank, the shank of each fitting being of the truss B and of such size that they will contact the interior surface of its walls to which they may be welded. The shanks are of cross section but slightly less than the internal diameter of the sleeve-like guides 28 so that a relatively firm slidably received in one of the said guide members to connect the latter with the truss when mounted therewith said fitting forming an anchoring means for the ends of the truss.
