GARAGE-DOOR OPENER.
Application filed April 28, 1926.
The invention relates to electrically operated mechanism for opening and closing the doors of garages and similar structures; and the object of the invention is to provide a motor operated mechanism including a shaft arranged to be intermittently rotated in the same direction to open. and close the doors, a pair of crank arms being fixed to the shaft, one above the other and located at suitable angles for the pivotal connection of links connected to the doors, a magnet controlled switch being provided for starting the motor and arranged to be automatically cut out by the door opening mechanism as the doors reach either the fully opened or fully closed positions.
An embodiment of the invention, thus set forth in general terms, is illustrated in the accompanying drawings, in which- Figure 1 is a plan View of the improved door opening mechanism applied to a pair of swinging doors which swing outward;
Fig. 2, a similar View of the mechanism applied to one single and one double door which swing inward;
Fig. 3, an enlarged plan fragmentary sectional View of the mechanism taken substantially on the line 33, Fig. 4;
Fig. 4, a vertical sectional view through the mechanism taken substantially on the line 4-4, Fig. 3, and
Fig. 5, an enlarged sectional view of the switch.
Similar numerals indicate corresponding part-s throughout the drawings.
The invention is adaptable to use upon any usual type of garage doors, such as the swinging doors 1-1 shown in Fig. 1 or the combination double hinged swinging doors 2 as shown in Fig. 2, and is adapted for opening and closing doors which swing either outward or inward, as illustrated in these two figures.
The operating mechanism is arranged to be suspended from the ceiling, indicated at 3, and is propelled by means of an electric motor 4, of any usual and well known type, supported upon the bracket 5.
Operation of the motor is controlled by means of a switch indicated generally at 6 and comprising the contacts 7 arranged to be engaged by the blades 8, which are carried upon the swinging arm 9, pivoted at its upper end as at 10 to the block 11. or
other suitable support.
Serial No. 105,115.
An angular bracket 12 is supported upon the block 11 and carries an electric magnet 13 arranged to attract the pivoted arm 9 when the circuit 14 is closed as by one or more push button switches 15, drawing the blades 8 into engagement with the contacts 7 and closing the circuit to the motor 4;
The blades are temporarily held in this posit-ion by means of the pivoted catch 16 until the same is automatically released, as will be later described, when the spring 17 throws the blades out of engagement with the contacts, breaking the circuit to the motor.
A housing 18 is suspended, spaced below the ceiling, as by the bracket 5 and an arm 19 and the shaft 20, from the motor, is journaled in said housing and provided with a worm 21 which engages a large gear 22, mounted upon the shaft 23 journaled verti cally within the housing.
A pinion 24 is mounted upon this shaft and meshes with the gear 25 upon the crank shaft 26, which is also journaled vertically through the housing.
A crank arm 27 is fixed upon the lower end of said crank shaft, beneath the housing 18, and a similar crank arm 28 is fixed upon the upper end of the crank shaft, these crank. arms being located at suitable angles to each other to provide for completely opening and closing the doors. A link 29 is pivotally' connected at one end to each crank arm and at its other end to the adjacent door or bracket 30 upon the door, depending upon the construction and arrangement of the door to be operated.
A rod 31, normally held in the inoperative position by a spring 32, has one end slidably located through the depending flange 12 of the bracket 5, and its other end slidably located through a depending flange 34 upon the housing 18. This inner end of the rod is substantially conical as shown at 35 and is arranged to be engaged by the radial fingers 36, fixed upon the crank shaft 26, as the doors reach the fully opened or fully closed position to move the rod 31 outward, against the pressure of the spring 32, engaging the angular upturned end 33 of the pivoted latch 16 and releasing the same from engagement with the blades 8, permitting the spring 17 to swing the arm 9, carrying said blades outward, opening the switch and stopping the motor at this point,
In operating the apparatus, assuming the doors are in the closed position as shown in full lines in Figs. 1 and 2, either of the push button switches 15 may be depressed to close the circuit to the magnet 13, drawing the pivoted arm 9 into the position shown in Fig. 41-, engaging the blades 8 with the contacts 7, the pivoted catch 16 being pulled up by the spring 39 to engage the blades and hold them in this position.
The motor is thus started and through the gearing, above described, rotates the shaft 26 substantially one-half revolution swinging the doors into the fully opened position.
At this point one of the radial fingers 36 engages the trip rod 31, pushing 519831116 outward, against the action of the spring 32, and releasing the pivoted catch 16, from the blades 8, the spring 17 throwing the pivoted arm 9 outward, withdrawing the switch blades from engagement with the contacts and" breaking the circuit to the motor.
To close the doors the operation is repeated, the crank shaft making another onehalf revolution in the same direction and being stopped in the position shown in full lines in Figs. 1 and 2.
It should be understood that the crank arms and radial fingers 36 may be adjusted with relation to each other upon the crank shaft 26 to accomn'iodate different styles of doors. It is also pointed 0th that althougl'i the gearing shown in Figs. 3 and i'may be desirable for cutting down the speed of the mechanism, the intermediate gearing 2 2 and 24- may be dispensed with and the worm 21 engaged directly with a suitable gear upon the crank shaft 26.
Attention is also called to the fact that the automatic tripping of the mechanism to stop the same in either the fully opened or fully closed position is carried entirely Within the mechanism itself dispensing with the necessity of providing any switch actuating device upon the doors to trip the mechanism at each extreme of its movement.
I claim:
Door operating mechanism for a pair of movable doors, including a rotatable crank shaft, a crank arm fixed to each end of the shaft, a link pivotally connecting each crank arm with one of the doors, means for rotating the crank shaft in one direction and means for automatically stopping the crank shaft as it completes one-half of a revolution In testimony that I claim the above, I have hereunto subscribed my name.
MORGAN J. LENIS.
