GARAGE DOOR.
Application filed November 20,1922. Serial 1T0. 602,014.
My invention relates to garage and other doors of like character, shown in the accompanying drawings and. more part cularly described in the following specification and 5 claims. I
The primary object of this 1nvent1on is to provide means whereb} a vertically movable door may be'easily raised and lowered-with the least expenditure of manual effort.
In carrying my invention into effect the door is preferably constructed of a plurality of horizontal panels hinged together adapted to be raised vertically to uncover the door opening, above which it is guided ln a substantially horizontal direction by sultable channelmembers extending upwardly and inwardly from the floor at each side of the door casing; one of the objects of my invention being to remove the door from frictional contact with the casing immediately upon being raised,the construction however is such that when the door is lowered it will be forced into abutting contact with the door casing to insure a tightand satisfactory closure.
A further object of the invention is to reduce the manual effort required to raise and lower the door,-a relatlvely long spiral spring being provided mounted upon a horizontal shaft journaled in brackets above the door,and adjacent to the ends of the shaft are secured rim pulleys on which are .wound metal tapes or other flexible elements attached to the lower panel of the door.
The spiral spring is connected at one end with a collar secured to the shaft and at the other end to a collar loosely mounted upon the shaft from which extends radially an arm, adapted to bear upon the framework of the building'or other suitable abutment,
. whereby upon lowering thedoor the spring will be wound-upon the shaft to increase its tension so that when it is desired to raise thedoor the effort necessary to lift the latter will be proportionately reduced through the matically locked w downward movement of the latter and thus avoid injury to anyone beneath the door at the time of the accident.
A further object of the invention is to pro vide means wherebly the door may be autoen closed.
A further object of the invention is to provide means whereby the door may be either manually or mechanicall actuated by an electric or other motor w ich may be distantl controlled from the garage, office or dwel ing. j
A further object of the invention is to provide means whereby the tension of the spiral spring wound upon the horizontal s aft may be regulated to adapt it to the weight of the door which it is adapted to control.
With the foregoing and other objects in view which will appear as the description proceeds the inventlon further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes may be made in the precise embodiment of the invention hereby disclosed without departing from the spirit of the same. 7 a
In the drawings accompanying this specification and forming a part thereof Figure 1 is a sectional elevation of the door and its casing taken on or about line 1-1 of Figure 8.
Figure 2 is a vertical cross-sectional view of a detail of construction taken on or about line 22 of Figure 1.
Figure 3 is a cross-sectional view of a detail of the lower portion of the door showing a modification in the arrangement of the roller and latch for automatically locking the door when closed;
Figure 4 is a horizontal sectional and plan view taken through the wall of the building above the door, showing a shaft journaled above the door carrying flanged pulleys with steel tapes wound thereon connected with'the door, also a spiral spring mounted upon theshaft adapted to assist in raising and lowering the door."
Figure 5 is a horizontal sectional view of a fragmentary detail of the door and its casing taken on or-about line 5-5 of Figure 8, showing one of the brackets secured to the door carrying a guide roller extending doorshowing the inwardly inclined guidechannels in which a plurality of rollers travel carried by brackets attached to the door whereby the door is directed to and from gether as at A the door-casing and horizontally above the' latter.
Referring now to the letters of reference placed upon the drawings A denotes a garage door comprising a plurality of horizontal panels A hinged to- Secured to the respective panels at each side of the door are brackets B on which are journaled rollers C extending into channel members D in turn secured by suitable brackets D to the, door casing E or other framework. The channel members D are inclined slightly from the floor to the topof the door casing ;they then extend in a substantially horizontal direction beneath the ceiling of the building. Thebrackets B carrying the roller C are respectively longer on each superimposed panel than the brackets secured to the panel directly below in order that the rollers may follow the inclined guide channel members I) to provide for a perfect closure of the door when lowered to the floor.
It'will be evident upon raising the door that it will follow the inwardly inclined channel members which serve to relieve the door from frictional contact with the casing,
that it may be raised bya minimum expend1-.
ture of effort.
F, F, are brackets bolted to journaled therein" above the door is a .hori zontal shaft G. p Adjacent to each end of the shaft-G is secured a flanged pulley H, on which is wound a-steel tape or other suit able flexible element I, in turn connected with a suitable engaging device J attached to a bracket secured'to each side of the door Y can be regulated by'adjustmg the loose collar adjacent its lower edge. V
Coiled upon the shaft G is a spiral spring K having one end secured to a collar K bolted or otherwisefastened to the'shaft. K is a collar loosely mounted upon the shaft G- the channel members or to the frame of thebuilding and.
' readily understood.
the spring K is also secured. Projecting from the loose collar K is an arm K pointed at its end as shown in Figure 2. Coiled upon the shaft G is a relatively light spring L; one end of which is bent to engage the arm K"the other end being secured to the frame of the building or other stationary support-the tension of the spring L being exerted in the opposite direction to that of the spring K, it only becomes effective upon the breakage of the latter whereupon the pointed arm K is turned, as indicated in dotted lines in Figure 2, that it may engage the door and thus arrest its downward movement.' i
M, M, are inclined spring latches, secured to brackets attached to the lower panel of the door, adapted to engage a suitable latch plate M M, bolted to the outside of the channel "members-see Figures land 8.
N, N, are flexible connections between the spring brackets and a rotatable plate N pivoted at N to the door panel. The plate N has a notch N to receive the spring actuated bolt of the lock N actuated by a key or other like device; Projecting from the rotatable disc are handles N for rotating the disc whereby the spring latches N, N, are disengaged from their latch plates following the withdrawal of the spring actuated bolt of the lock N from the notch N in the disc.
'N denotes a handle for manually raising and lowering the door. P, indicates an clectrio motor-see Figure 4-with a pinion Q,
on its armature shaft in mesh with a gear R, secured upon the end of the shaft G, by the operation of which the door may be raised or lowered as required from a distant point and without manual effort.
In Figure 3 has been shown a modification of the latch engaging member M bolted between the flanges of the channel, in this case the guide roller C which also travels inthe channel members are above the latch plate.
In Figure 7 is diagrammatically shown a single panel door, provided with pulleys C respectively located at the top and bottom of the door only, to guide the door upon traversing the inclined channel members.
Having now indicated the several parts of my invention by reference letters the construction and operation of the same will be Assuming the door to be closed the locking latch may be operated to release the door in the manner previously explained. The door ma then be readily raised through the actidn -o the'spring K,-the tension'of which K along the shaft G, whereby the effective that theshaft may turn thereinto which of the door. As the door is raise itwill be tight closure with relation to the door open forced out of contact with the door-casing by the inclined guide rails or channels D, D, thereby releasing it from the frictional drag that might otherwise occur when raising or lowering the door. I
Upon lowering the door it will be forced to a tight closure upon reaching the floor by the brackets of relatively different length carrying the rollers that traversethe inclined channels at each side of the door.
As previously indicated the door may be mechanically raised and lowered by an electric or other motor which may be operated from the garage, ofiice, dwelling or other location as will be readil understood.
