BACKGROUND
DESCRIPTION
The present invention relates to barrier movement opera
tors and particularly to such operators which include a timer
to-close feature.
20
FIG. 1 is a view of a barrier movement operator embodying
Barrier movement operators are known which include a
motor for moving a barrier between open and closed positions
and a controller for selectively energizing the motor to move
the barrier. Gate operators and garage door operators are
examples of the wide range of such barrier movement opera
tors. The controller of a barrier operator may be responsive to
stimulus signals to perform various barrier movements with
safety. For example, the barrier operator may include a con
trol switch which, when pressed, reverses the direction of
travel of the barrier or starts the barrier moving toward the
open or closed position.
Most door movement has, for safety concerns, been under
the control of a human operator. That is the barrier was
opened or closed only when a human was present to provide
a movement initiating stimulus. The human, being aware of
the environment was a signi?cant part of safely moving the
barrier. Humans, however, are not infallible and occasionally
the barrier is left open when it should be closed. Doing so may
be energy inef?cient by allowing heat or cool to escape from
25
operators, rolling gate operators, swinging gate operators,
other types of balancing such as tension spring, and other
types of movement such as high lift and powered rail and

to-close feature is generally equipped with special safety
equipment like an alerting light and/or audible signal which
ment may be detected by an optical transmitter 138 and
receiver 142 which “watch” the door opening to detect when
an obstruction is beneath the door. Similarly, an optional door
edge sensor (not shown) may be attached to the bottom of the
door to detect physical contact with an obstruction.
When the barrier movement system is installed, the con
troller 208 is taught the open and closed positions of the door
by known means so that the motor 150 is energized only long
enough to move the door between those limit positions. Such
limit positions may be learned in the software and data of

It may be desirable for a user to pause the timer-to-close

In the embodiment of FIG. 1, a panel door 112 is raised and

In order to combat the problem of a left-open barrier, some
systems include a timer-to-close feature. This feature gener
ally includes a timer which is enabled when the barrier is in
the present invention. FIG. 1 shows a jack shaft balanced,

improvements described and claimed herein apply to other
types of barrier movement systems such as commercial door

physical switches within head end 102 which sense the move
ment of representations of the door position. FIG. 3 repre
sents one apparatus internal to the head end for setting limits
of door travel.
The limit setting arrangement of FIG. 3 comprises a ?rst
limit switch 145, a second limit switch 146, and a third limit
switch 147. Each limit switch includes an actuator lever, e. g.,
reprogramming of the parameters of the feature. A need exists
148, which responds to contact by causing its associated
for a more convenient arrangement for pausing a timer-to
switch to change from an open to a closed electrical state. The
state of all switches is reported to controller 208 via a com

Further, known operators having a timer-to-close feature

or for reasons predicted by a human operator. A need also

As discussed With regard to FIG. 3, the barrier movement
operator described herein includes a limit sWitch 147 and
corresponding limit cog 153 Which may be adjusted to iden
tify to controller 208 a position of the barrier intermediate to
the positions identi?ed by sWitches 145 and 146. The point at
Which sWitch 147 changes state is adjusted in the manner
described previously With regard to sWitches 145 and 146.
With such adjustment, the controller 208 Will be informed
each time the door passes the intermediate position While
After setting open and closed limits, controller 208 can accu
rately control barrier movement.
After the barrier operator is installed, a user may press the
command button 134 of Wall control Which signals controller
208 via a path 126. Controller assesses the present state of the
barrier based on various inputs discussed and sends a signal
on a communication path 220 to control relays 222 Which
apply poWer to motor 150. For example, When the barrier 112
is at the open limit and push button 134 is pressed, controller
208 energizes relays 222 to energize motor 150 to move the
barrier toWard the closed limit. During such movement the
optical sensors 138 and 142, and other safety equipment, are
20
moving betWeen open and closed positions. In the present
embodiment, the passage of the intermediate position While
the door is traveling upWardly toWard the open position is

operation of this feature. A sWitch 132 of Wall control 134 is
used to enable and disable the timer-to-close feature.
FIG. 4 is a How diagram of an embodiment of the timer

In the embodiments discussed above, the barrier Waits at
