DOOR STOP
Birkelund Hansen, San Francisco, Calif.
Application October 2, 1937, Serial No. 166,993
5 Claims. (01. 16-137) '
The present invention relates to improvements
in door stops, and has particular reference to a
stop that is adapted for holding a door in open
position.
In making repairs on an automobile and servic
trated a body post I having a door 2 secured
thereto by means of a hinge 3 in the usual man
chanic to gain access more easily to the different

parts.
It will be understood that when the door is closed
the faces 6 and ‘I of the body post I and the door
2, respectively, contact one another. Figure 1
shows the door after it has been opened to a posi
-An object of my invention is to provide a door
20 stop, which is adapted to be fastened to one of
the door hinges in such a manner that the stop
will hold the door against closing until such time
as the stop has been removed.
A further object resides in the provision of a
25 door stop that will allow further opening of the
door from an initial open position.
The stop is
made for automatically extending itself when the
door-opening is widened so as to maintain con
tact with the door.
A still further object is to provide a door stop
30
that will automatically lock itself against return
movement in any position to which it may be ex
tended.
Moreover, I propose to provide a door stop
35 adapted to be applied to the hinges on either side
of the automobile or the like, and which will be
?rmly anchored in position after being attached
thereto.
Other objects and advantages will appear as
_ 4,0 the speci?cation proceeds, and the novel fea
tures of my invention will be particularly pointed
out in the appended claims.
For a better understanding of my invention
reference should be had to the accompanying
45 drawing, forming part of this application, in
which:

Figure 1 is a fragmentary horizontal sectional
view taken through a body post and a door, the
latter being open, and showing my door stop in
operation;
Figure 2, a sectional view taken along line 2—2
of Figure 1;
Figure 3, a face view of my door stop; and
Figure 4, a plan view thereof, parts being shown

Referring to the drawing in detail, I have illus

It is proposed in this connection to provide a
stop, which may be readily‘applied in place for
holding the automobile door open. It will, of
15 course, be understood that my door stop is not
to be limited to this particular use, and I will
describe the stop with reference to an automobile
door merely by way of illustration.

Although I have shown only the preferred form
of my invention, it should be understood that va
rious changes, or modi?cations may be made
within the scope of the claims hereto annexed
without departing from the spirit of my invention. 5

ner. The hinge comprises two straps 4 and 5.,
tion at right angles to the side 8 of the automobile. 15
My door stop is indicated generally at 9 in the
several views, and includes in its structural fea
tures a substantially T-shaped body member ID,
having the arms ll of the T slotted, as at l2, for
20
engagement over the hinge strap 4.
The stem I4 of the T-shaped body member
extends through the space, which is de?ned be
tween the body post and the door when the latter
is opened, and in Figure 1 the stem is substan
tially parallel with the automobile side 8. The 25
free end of the stem [4 has a squared opening
I5 formed transversely therein for slidably re
ceiving a rod I6, the latter also being square
in cross-section. It will be understood that
the opening I5 and rod "5 may be round, if 30
desired.
In Figures 1 and 4, I show the rod It as hav
ing an enlarged head H, which is urged away
from the stem M by means of a spring l8 work
ing between the stem and the head. The latter
abuts the face 1 of the door in the manner
shown in Figure 1 in normal operation. Upon
opening the door wider, the head is maintained
in contact with the door by means of the spring
I8, and the latter at all times prevents the stop
from accidentally becoming disengaged from the
hinge strap 4.
'
For holding the rod I6 against return move
ment in any position to which it may be ex
tended, 1 form ratchet teeth l9 along the length
of the rod, which are engaged by the pawl 20,
(see Figure 4). The pawl is urged into the
as
space between the teeth by means of a spring 2|
interposed between the squared head 22 of the 50
pawl and a sleeve 23, the latter being threaded
into the end of the stem l4.
A handle 24 may be manually retracted for
disengaging the pawl from the ratchet teeth and
thus allow the head IT to move toward the stem

I4. The head 22 of the pawl may be guided
in a squared guideway 22', if desired.
The rod It extends laterally from the stem
at right angles with respect to the arms ll of
the
door-abutting
opened into substantially the position it occupies
in Figure 1.
Having thus described the various parts of
my invention, the operation of the door stop
may be readily understood. The door 2 is ?rst

It is apparent that upon opening the door 2
further the head I‘! is maintained in contact
with the door by means of the spring 18. The
20 rod [6 moves to the right in Figure 1 as the door
opening is widened, and the ratchet teeth l9 are
free to move beneath the pawl 20. However the
rod is held against return movement from any
extended position by means of the pawl, unless
25 the latter is ?rstv released by manually retract
ing the handle 24.
When the door stop is applied to the right
hand door of the automobile, with the hinge ar
ranged at the front of the door, the slot I2’ is
30 engaged over the hinge strap 4'. Upon applying
the stop to the left-hand door, with a similar
matically locking the door-abutting means in
strap, and a rod adjustable transversely in the
member and arranged for abutting a door for
holding the latter against closing, the rod having
ratchet teeth thereon, and a pawl engaging the 20
ratchet teeth for locking the rod against return
movement after the rod has been extended from
the member.
