Application June 22, 1937, Serial No. 149,736
8 Claims. (01. 16-86)
Our invention relates generally to means for
this instance is made of suitable compressible
cushioning the slamming of a door, and particu
and resilient material, such as rubber and com
larly to means of this character which is mounted prises
an elongated shank on one end of which is
on the door and occupies a position between that
an integrally formed eye 2 which has the opening
' part of the door which ordinarily strikes the jamb
in closing, and the jamb itself, in the form of a 6 which frictionally receives the shank portion 3 5
of the door handle 4 closely adjacent to the in
compressible or shock absorbing pad, and an im
ner
surface of the door 5. The remaining end of
portant object of our invention is to provide sim
‘ple and effective means of this character which the shank of the bumper has a cross head 1 in
10 can be constructed in various ‘inexpensive forms. tegrally formed thereon which is adapted to as
Another important object of our invention is sume, normally, a position between the inner side
of the free edge of the door 5 and the opposed face
to provide bumper means of the character indi
cated which is adapted to be mounted on one of of the door jamb 8 on the door frame 9 as par
the door handles and frictionally engaged there
with ina manner to rotate with the door handle
so as to be positioned by the door handle normally
in the shock absorbing position.
Another important object of our invention is
' to provide bumper means of the character indi~
i 120 cated above which has a carrying portion secure~
ly fastened to the door handle by means of struc
vture already present on the conventional door
' handle, and whereby the bumper means is posi
, tively positioned by reason of the position of the
1' door handle.
Other important objects of our invention will
be apparent from a reading of the following de
scription taken in connection with the drawings,
wherein for purposes of illustration we have
shown preferred embodiments of our invention.
In the drawings:--
.
Figure 1 is a general elevational view of the
_ inner side of-a door showing an embodiment of
the invention mounted on the door handle there
ticularly well illustrated in Figure 2 of the draw
ings. The opening 6 in the eye of the bumper is
small enough to produce a strong frictional ?t
on the shank of the door handle, so that it will be
substantially securely mounted thereon and will
turn with the door handle when the door handle
is turned. The bumper is so positioned on the
shank of the door handle that when the door ,_
handle is in the normal unoperated position the
head 1 will lie in the position shown in full lines
in Figure 1 and Figure 2 of the drawings, so that
should the door he slammed from an open posi
tion, the head 1 of the bumper will absorb the
shockand prevent injury to the door and the H) CH
door jamb as well as reduce the noise ordinarily
occurring in the slamming of a door.
Referlng now to the embodiment of the inven~
tion shown in Figures 6 and 7, the numeral ID gen
erally designates the embodiment which in this
instance comprises a flat metal spring arm ll
.which is inserted in and fastened at one end in
a resilient compressible material head 7a and
has its opposite end 'bent into a coil I2 and of a

zontal section showing the relationship of the diameter permitting the telescoping of the shank
door, the bumper and the door jamb, and the ‘portion 3a of the door handle 4a» thereinto. The
manner in which the bumper is mounted on the
door handle.
,
Figure 3 is an end or edge elevational view of
Figure 1.
Figure 4 is a side elevational view of the bumper
per se.
'
Figure 5 is an end elevational view of Figure 4.
Figure 6 is a view similar to Figure 2 but show
ing'a modi?ed form of bumper.

\
Figure 7 is a longitudinal vertical sectional ‘view
taken through Figure 6 approximately on the
line 'l---'! and looking upwardly in the direction of
the arrows.
‘
Referringin detail to the drawings, and with
particular reference to the embodiment of the in
vention shown in Figures 1 through 4, the numer
al I' generally designates the bumper which in
free end of the coil I2 is provided with an opening
l3 to receive the set screw M which is normally
existent on the door handle for engaging the
squared shank l5 of the door handle axle where
by the door handle is secured in place on the axle.
The screw I4 is passed through the opening I3
and threaded into the shank 3a, so that the mem
ber l I extends exactly in the position required to
place the cross head ‘!a in the shock absorbing po
sition relative to the jamb 8d of the door frame 9a
and the inner face of the door Set as illustrated in
Figures 6 and 7, while the door handle 4a is in
its normal or initial position. When, the door
handle 4a is rotated in looking the door to close
the same, the bumper will be carried by the mo
tion of the door handle to an inoperative position
such as those indicated in dotted lines in Figure 1
of the drawings.
