This invention relates to a garage door, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the means employed for holding'the door fast to its closed position and facilitating the opening and turning of the door within a prescribed space as pointed out in the claims for novelty following a description in detail of the preferred features of construction.

The objects of the invention are to facilitate the operation of vertical sliding or rolling garage doors in which the doors disappear into the garage, and take their places under the ceiling in the least possible space, to put it in another way, to increase the height of the garage door to the fullest extent in relation to the height of the garage; to simplify the mechanism in these sliding lifting doors so that the hardware parts may be comparatively few in number and require the minimum of machine work to finish; to maintain the doors at a reasonable cost; and generally to insure efficiency and duration in so far as garage doors are concerned.

In the drawings, Figure 1 is an elevational view of the track and an end elevational view of the door in its closed position.

Figure 2 is a front elevational view of the door broken away showing the track and door frame.

Figure 3 is an end elevational view of the door in its open position showing the track.

Figure 4 is a cross sectional view of the door frame track and door.

Figure 5 is a perspective detail of the rolling anchoring bars.

Figure 6 is a cross sectional view of the track and binding cam.

Figure '7 is a reduced front elevational view of the door.

Figure 8 is an enlarged elevational view of the track and the supporting angle iron for its pivoted section showing the parts incidental to the closing movement and the position of the door in dotted lines.

Figure 9 is an elevational view of the track broken away at the inner end showing the position of the door in its partly open position in dotted lines and the position of the pivoted secrelative positions of the angle iron and the wall to which it is secured, and a pivoted track section.

Referring to the drawings, the numeral 15 indicates the ceiling sections of the tracks, which extend from the upper end of the door frame 16 inwardly and are supported by the suspending brackets ll from the ceiling, these tracks turning at the corner formed bythe door frame and the ceiling in the arcuate lengths i8. '10

The pivoted sections 22 of the tracks are supported by the vertical angle bars 19 which are rigidly bolted to the door frame and the track lengths swing on the section 26 of the angle bar from the pivot 23 at the lower end. These 15 track lengths being secured in the slots 21 in said section 26 by the headed pins 24, therefore these pivoted lengths swing from the bottom to and from the door frame out of alignment and into alignment with the arcuate sections of the track.

The strap brackets are secured to the wider upper portion of the section 26, therefore the track and door are pushed in to the door frame very closely by the rollers 21 in fact they really push the door to the frame.

The door itself is made up of horizontal divisions or sections 28, which are hinged together by the end hinges 29 and the middle hinges 30.

The pins 3| of the end hinges extend beyond the barrels of the hinges and carry in the first 30 place the pressure rollers 2'! and the runner rollers 32. These runner rollers 32 travel in the G- tracks l5 and carry the door with the track in pushing it tightly to the frame in its closed position.

The door at the upper end is pivotally secured to curved levers forming the anchor bars 33, these anchor bars having the pivotally mounted rollers 34 running in the tracks l5 and bearing during the operation in the loop extensions 35 from the arcuate lengths iii of the track. These arcuate lengths are rigidly secured to the plates 31 to connect the fixed track portion to the pivoted track sections 22.

The S-shaped anchor bars 33 are really links from the upper end of the door to the tracks and therebeyond and the rollers 34 in said s-shaped bars or links run in the tracks from the middle of the arcuate track sections to the end of the track sections l5, though in the operation these links hold the door to the track and guide it in passing the corner or arcuate sections of the track and it is by means of these S-shaped bars that the door swings around, for as explained, the rollers 38 bear on the loops 35 and guide the topmost section of the door around the curve in such a manner as to hold it closely therein and as the door continues to move inwardly it draws the S-bars with it.

The helical springs 39 are hooked at one end 46 to the inner end of the horizontal lengths 36 of the tracks I5 and at their outerends carry the pulleys 4i journalled in the pivot bearings 42.

The pulleys 43 are journalled in the pivot bearlngs M5 on the plate brackets 31, and the cables 45 extending from the arms 46 at the lower end of the door, are trained over the. pulleys 43 and ti and brought back to the plate brackets 31 and there secured at 41, thus the door itself lifts very easily and swings around to an open position.

The lugs 48 from the anchor bars, assuming the door is in its horizontal position, rest on the plates 49 and are carried with the door to the inner position.

In the operation of this invention, the door is in a partly balanced position, through the spring and the cable but there is nothing of any great importance in this part of the invention, for it is well known to use springs in balancing the weight of a door.

The door in rising from its closed position simply slides up the track sections 22 automatically aligning said track sections with the track sections it. The upper end of the door carries the two links which also have running rollers. As soon as these links reach the curved or arcuate sections of the track the top section of the door is drawn in the direction of the track and this throws the end down so that the pin at the inner end of the link drops down and bears on the loop forms of bearings, thus taking the weight off the running rollers of the door itself and just so soon as the upper door section is swung around into the horizontal fixed section, the door drags the links along with it until they reach the plates 49 on which they rest.

At the closing of the door the track sections 22 and 18 are in alignment, so the door simply travels from its horizontal position around the arcuate section and into the vertical sections or pivoted sections just as the links on the return journey advance in the arcuate sections l8 and are swung around in the loop bearings, drawing the upper door section with them.

The pressure rollers come into action through engaging the strap brackets which push the pivoted section at the upper end in the direction of the door frame for the strap brackets engage the rollers and this moves the whole door in the direction of the door frame The S-shaped brackets remain in the track in a position approximately central in the arcuate sections of the track.

The vertical sections of the track are now pushed over quite out of alignment withthe arcuate sections and the door reaches its lower position where it is pinched into the proper tight hold against the door frame at the lower pivoted ends of the vertical lengths of the track.

on their pivots, the headed rivets merely holding them from falling away from the angle post and not in any way combining with the slots in said track sections to alter the position of the latter for releasing the pressure on the door or restoring that pressure.

The first movement as explained, releases the cam rollers, which is practically instantaneous with the door movement in leaving the sill.

The track sections are then free to find their alignment with the arcuate track sections and there can be no binding of the uppermost panel, for it is moving upwardly with the track sections in their same positions as when pressing against the door, for it will be noticed that there is a distinct length between the door roller and arcuate track section.

In other words, the top panel of the door can be lifted upwardly on the inner pivoted tracks in their pressure position until the split between the upper panel and the next lower panel reaches the arcuate section and for this purpose, there is quite suflicient play in the structural features of the door to permit the anchoring levers or links to roll on before beginning to turn over into the loop 35, for that begins to happen when the split between the upper panels reaches the arcuate sections and in actual operation no such trouble as binding or anything of the like has occurred.
