Nov. 3, 1936., H. G. KELLY 2 9 ROLLING DOOR MECHANISM Filed Feb. 27, 1932 v a [I m J T m 11 Ii I r 26 g 8111mm 17 .2 Fg'y y 71 W Patented Nov. 3, 1936 UNITED STATES PATENT OFFICE 9 Claims.

The present invention relates to a movable support of the rollers of a sectional door and a means for moving such a door laterally at the end of its downward closing motion.

The objects of the present invention, among others, include the following:

An improved hinged support; for the spindles of rollers associated with the sections of a door moving outwardly and-downwardly to close an opening in a wall.

A new spring attachment to said hinged support to hold the door inwardly away from frictional contact with the frame of said door opening except when counteracted by a superior force.

A new means of overcoming such inward spring action on a door and imparting instead an outward lateral displacement of the door into contact with the stops of a door frame at the end of the closing movement of the door.

A new hinged roller support for a sectional door assuring level support of the open door and movable support in its final closing and initial opening movement.

The cooperation of the above means with a countcrbalancing means described in a pending application of the applicant and of Serial Number 525,572.

These and such other objects of the invention as may hereinafter appear, are obtained by the novel construction, unique arrangement, and improved combination of the elements illustrated in the accompanying single sheet of drawings disclosing several forms of the invention, and in which:

Like reference characters are used to designate similar parts in the drawing and in the description of the invention which follows.

The invention is adapted particularly for use in a garage or an industrial building having a relatively low ceiling.

In a wall it] of a building having a relatively low ceiling (not shown) is shown a door opening ii bounded on three sides by frame members i2 carrying stops i3 having a face It opposed to a sectional door i5 for closing the door opening I l on either side of the door opening II and have a face I! opposed to the lateral edges of the closed door l5.

Door l5 consists of an uppermost section it and lower sections l9 joined together by hinges 20. For guiding the movement of door l5 from a vertical position, in which the door opening ii is closed, upwardly and inwardly to an horizontal position above the door opening I l, is a track M on either side 01 the door opening ii. The track consists of a vertical track section 22, a continuing curved track section 23, and a horizontal track section 24, the latter being for the support of the door l5 in its open position.

Within track 2i is an uppermost roller associated with the uppermost door section i 8. Other rollers 26, associated with door sections it and Marc also associated with the track;

In Figures 1, 2, 4 and 5 is shown a movable support 21 for lower rollers 26 of door sections it and i9. Rollers 26 are adapted to rotate freely on the spindles 28 extending into the sleeve 29 of a hinge member 30 carrying an opposed parallel sleeve 3i. Sleeves 29 and Ill of said hinge are connected by a fiat member 32. Within sleeve M is a spindle 33 passing through opposed holes 34 in wings 35 of a bracket 36 secured to lower door sections l9 and the lower portion of the uppermost door section It. A stop edge 3i is articulated from the bracket 36 to abut the hinge leaf 32 in its pivotal movement to limit the movement of the door l5 toward spindle 28 at a predetermined distance from said spindle.

Bracket 36 carries a spring 38 with one end 39 In Figures 1, 2 and 3 is shown a movable support 42 for the upper portion of uppermost door section I8.

In movable support 42 there is an uppermost roller 25 adapted to rotate on a spindle 28a held by a hinge member 38a. Comprising the movable support 42 is a bracket 42a and a spring 42b similar to the brackets 36 and springs 38 of movable supports 2'I, the main difference being that the flat member 32a of the uppermost hinge member 38a may be wider than flat member 32 of the hinge members 30. The stop edges 31 of all brackets 36 and the stop edges 31a of the bracket 42a are placed at the same distance from door I5.

It will be noted that there is room for very little lateral movement of the

rollers

25 and 26 within the

track sections

22, 23 and 24 so that the hinged connection of

rollers

25 and 26 with door I5 provides for a lateral movement of door I5 relative the track sections. Normally all sections of the door I5 are held parallel to track sections 22 or 24 by the action of the springs 38 and 4227 as limited by stop edges 31 and 31a.

It is also evident that the projection of the spindles 28 and 28a into sleeves 29 and 29a respectively is telescopic whereby lateral expansion or contraction of door I5 may be readily accommodated.

Uppermost hinge member 30a of movable support 42 carries perpendicular to the outer edge of the section 32a a fiat member 44. The member 44 is perforated with a hole 45 to receive a spindle 28a, and another hole 46 to receive a spindle 33a. Flat member 44 carries along one edge a perpendicular flange 41 having a face 48 inclined downwardly toward the plane of the member 32a.

For contacting with the outer face 48 of flange 41 is a roller 49 adapted to rotate on a spindle 50. The latter may be secured to the track section 23 or to the wall II) as desired. The spindle 50 is to be located a greater distance from door I5 than is the track section 23. As the closing motion of the door I5 nears completion, the outward face 48 contacts with the roller 49 to impart an outward motion to the uppermost spindle 33a and uppermost bracket 36a to pivot them about the spindle 28a. This pivoting motion is had against the urge of the spring 42b and results in the forcing of the upper portion of the uppermost door section I8 outwardly into weatherproof contact with faces I4 of stops I3.

Commencing with the initial upward and opening movement of door I5 the outward pressure imparted to the uppermost door section l8 by the angular contact of the angularly inclined face 48 of the flange 41 is gradually lessened to permit the inward urge of the spring 42b of the movable support 42 to draw the uppermost door section away from the stops I3.

A means for counteracting the force of the springs 38 and for forcing lower door sections I9 and the lower portion of uppermost door section I8 outwardly into contact with the stops I3 at the completion of the closing movement of door I5 is shown in Figures 1, 2, 6, '7, 8 and 9.

Attached to face ll of frame member I6 opposite upper door section I8 is a strike plate 52 having a perpendicular flange 53 on its lower edge. Strike plate 52 furnishes a lug 54 for the anchorage of one end 55 of a spring 56 having another end 51 anchored to a movable arm 58 extending downwardly of the strike plate 52. The contractual movement of the spring 56 is limited by the abutment of the flange 53 with a similar flange 59 along the upper edge of movable arm 58.

Projecting at intervals from a face 60 of movable arm 58 which is opposed to the lateral edge of a closed door I5 are pins 6|. Pins 6| extend through slots 62 of cam plates 63 which are rotatable about pintles 64 of attachment plates 65 secured to face I! of frame I6.

Extending perpendicularly from a face 66 of each cam plate 63 to project adjacently behind the face of a closed door I5 is a pin 61. The pin 61 is positioned below slot 62 and the pintle 64. In all cases the pintle 64 is located beyond the slot 62 toward the door opening I I.

It will be noted that any downward motion of movable arm 58 will impart a rotating motion to cam plate 63 about pintle 64 by means of the engagement of the moving pin 6I with the lower edge 68 of the slot 62. Said rotating movement of the cam plate 63 about the pintle 64 located upward and outward the pin 61 imparts to said pin 61 an outward motion toward the door opening II.

A downward movement is imparted to movable arm 58 at the completion of the closing movement of door I5 by the contact of the spindle 69 of the lowermost roller 26 with an upper edge III of an horizontal extension II configuring the lower end of the movable arm'58.

The extended end 13 of each pin 61 extends inwardly beyond the lateral edge I4 of door I5 when the door is in a vertical position. During the initial major portion of the closing movement of the door I5, said door passes between the pins 61 and the door stops without frictional contact with either.

When the closing movement of door I5 nears completion spindle 69, which projects inwardly beyond the sleeve 29, makes contact with the edge I0 of the aforesaid extension 'II to force said movable arm 58 downwardly. This downward movement of the arm results in a rotation of cam plates 63 whose pins 61 are thereby moved outwardly to first contact the inner face 15 of door I5 and then force the door outwardly against the urge of the springs 38 and into weatherproof contact with faces I4 of stops I 3. The action just described takes place coincidentally and in full co-operation with the previously described lateral closing motion of the upper portion of door section I8.

Contact plates 16 may be attached to face 15 of door I5 at each point for contact by the pins 61 therewith to prevent damage to said door by said pins.

Commencing with the initial opening movement of the door I5 the downward pressure of lowermost spindle 69 on extension II of movable arm 58 is gradually released thus permitting the spring 56 to raise the movable arm 58 until flange 59 of said movable arm contacts with flange 53 of the strike plate 52. The upward movement of the movable arm 58 imparts to all cam plates 63 a rotating motion in a direction opposite to that effected during the final closing movement of door. Hence there occurs an inward motion of the pins 61 to release the force counteracting the outward force of the springs 38 on the door I5; said door then being drawn inwardly by said springs 38 away from its contiguous position with faces I4 of the stops I3.

The release of the force counteracting the inward force of lower springs 38 during the initial opening movement of door I5 just described takes place coincidently and in full co-operation with the release of the force counteracting the urge oi uppermost spring 38, whereby all sections l8 and is are withdrawn from the stops l3 simultaneously.

As the opening movement of the door l5 continues, the contact of the lowermost spindle 89 with extension ll of movable arm 58 and also the contact of pins 61 with contact plates 16 of door surface 15 is broken and the forces counteracting all springs 38 being thereby removed the resultant inward movement imparted to all sections i8 and IQ of door i5 continue under the impingement of theirrespective springs 38 and 421) until said inward movement is stopped by the contact of the stop edges 31 and 31a with th respective pintled members-32 and 32a.

The hinged members 32 and 82a which are drawn by springs 38 and 42b into respective con tact with stop edges 31 and 31a, which are located a uniform distance from door I5, makes it evident that the supporting

rollers

25 and 26 carried by the hinged members will be an equal distance from all door sections. This provides that the door i5 will be supported, while in its open position, in an undistorted plane parallel to the horizontal track section 24.

In the application of the described closing means for the doorsections i9, the movable arm 58 is placed upright a predetermined distance from the floor.

with the flange 59 of the movable arm 58 and spring 56 is co-anchored to the strike plate 52 and the movable arm 58.

Cam plates 63 are placed with their slots 82 circumjacent to the pins 6i and have an edge ll perpendicular to face Id of the vertical stop l3 when said door is open, said perpendicular edge 11 being a guide for the application of attachment plates 65 in uniform relation.

In Figure 1 the effective weight of door i5 is shown counterbalanced by a counterbalancing means fully described in the before noted and pending application of the applicant, Serial Number 525,572. In the present instance a cable having one end Bi secured to a lower portion of the door i5 winds on a drum 82 coincidently with the unwinding of another cable 83 from the drum 84, the latter rotating only in unison with drum 82. The free end 85 of cable 83 is secured to one end 86 of an extensiblespring 81 whose other end 88 is anchored to a fixed support 89.
