2 Claims.
This invention relates to a device for holding a
door in an open position. The art of door hold
ers is a very old one, and even the patented art
has been very highly developed, so that there
5 are a great number of patents showing door hold
ers of all types.
My invention
comprises an
which, though quite narrow in character, is nev
ertheless of considerable commercial value and
10 does present quite a forward step.
The commercial development of door holders
has been such that the trade has generally ac
cepted the association of a door bu?‘er and a door
holding hook as a working combination. To use
15 a hook alone, would permit the door to be in
jured when opened against the hook or its mount
ing. The door buffer protects the door from the
hook, the hook being available, however, to en
gage the door and hold it open when desired.
door holding hook and buffer, in the prior art,
20 usually comprises a metal buffer holder in which
a resilient buffer is mounted and held, and a door
holding hook mounted on an eye formed on the
buffer holder.
Since doors are made to open to the right and
to the left, it has been customary in this art to
mount the eye on which the holding hook is car
ried, on one side or the other of the buffer, de
pending on whether or not the buffer is to be
used with a right hand or a left hand door. For
30 many years door buffers and holders have been
sold in this way; that is, the combination of a
buffer and hook, with the hook mounted either
on the right or left hand side, and the trade has
always ordered left hand or right hand buffers,
depending on the direction of opening of the
door with which a buffer is to be used.
I have made a radical improvement over the
prior art by mounting my hook holding eye on
the upper surface of the metal buffer holding
4.0 portion, so that the hook is now capable of co
operation with either a right or a left hand door.
It has been found that when the hook is so
mounted, it many times drops into position on
the buffer when released from the door and does
45 not drop into a downward position out of the
way of the buffer.
I have found that by particularly shaping the
upper surface of the buffer, as in the form of
an inverted V, the hook when dropped on the
50 buffer will be cammed by this inverted V into
a downward side position out of obstructing re
lation to the buffer. This general combination,
including the mounting of the hook and the
guiding thereof, I believe, is a very radical im
55 provement in the art, and I shall claim it and the
sub-combinations thereof broadly in the claims
which are appended hereto.
While I propose to form the inverted V on the
metal portion of the buffer, or the buffer holder,
it could, of course, be formed on the buffer por
tion per se, as will be readily appreciated by those
skilled in the art.
It will probably be helpful now to refer to the
accompanying drawing for a description of a
particular modi?cation of my invention. In the 10
drawing, Fig. 1 is a view showing a buffer-holder
combination, with the holding hook holding the
door in open position.
Fig. 2 is an end view and
section of the buffer and the holding hook, show
ing the hook as it falls down on the buffer when 15
released from holding position on the door. Fig.
3 illustrates just how the hook is cammed into
one of two side positions.
Referring now more particularly to the draw
ing, reference numeral I0 designates the metal 20
portion or buffer holding portion of a buffer held
vby screws ll against the floor. It is possible, of
course, to use a wall type of buffer in my device.
In so far as my invention is concerned, it is im
material whether the buffer is mounted on. the
floor or on the wall.
The screw I2 is cast integrally with the portion
In with its tapered screw portion 12 within an
open socket 14, into which a removable resilient
buffer body I5 is inserted and preferably rotated
so as to be held ?rmly by the screw portion l3 of
the screw l2.
An eye 16 is formed on the upper surface of
the buffer holder l0 and has mounted thereon a
hook I‘! which may engage an eye l8 carried by
a door l9. It is obvious that in this sort of ar
rangement, the hook I‘! is adapted for coopera
tion with either a right hand or left hand door,
so that it is no longer necessary for buyers of
such devices to specify right or left hand devices.
In order to prevent the hook from remaining 40
on the upper surface of the buffer body I9 when
it is released from the eye l8, the upper surface
of the body I0 is formed with an inverted V-por
tion 20 cooperable with a rounded surface on the
hook I‘! for camming the hook I‘! into its full
line or dotted line position, illustrated in Fig. 3.
The invention will now probably be quite clear
to those skilled in the art.
I now claim:
1. In a combined door buffer and door holder,
in which the door holder is a hook carried by
means ?xed to the door buffer, and the buffer
has a rubber buffer portion, means supporting
said hook above said rubber buffer portion so.
that said hook will have a tendency to drop there 55
on when released from the door, and a V shaped
said hook above said rubber buffer portion, and
lug on the surface of the buffer directly under
said hook for guiding said hook into a downward
for directing gravitational movement of said
hanging position in non-obstructing relation to
the rubber buffer portion.
2. In a combined door buffer and door holder,
in which the door holder is a hook carried by
means ?xed to the door bu?er, and the buffer
has a rubber bu?er portion, means supporting
a specially shaped upper surface on the bu?‘er
hook into a downward hanging position in non
obstructing relation to the rubber bu?er portion 5
when said hook is released from holding rela
tion to the door.
