Abstract
A door lockset comprises a transmission assembly comprising a chassis with two through-holes, an outside handle assembly, and an inside handle assembly. The outside handle assembly comprises an outside handle, an outside rose, and an outside rose liner. The outside rose liner has at least two pairs of diametrically disposed positioning holes selectively aligned with the through-holes of the chassis. The outside rose liner further includes two engaging posts each having a screw hole. The inside handle assembly comprises an inside handle, an inside rose, and an inside rose liner. The inside rose liner includes two holes aligned with the screw holes of the engaging posts.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a door lockset that can be mounted to doors with different locations for positioning holes.
2. Description of the Related Art
A door generally includes a p air of diametrically disposed positioning holes through which two bolts are extended. Namely, the bolts are extended through a pair of diametrically disposed holes in the inside rose liner, the pair of diametrically disposed positioning holes in the door, and screw holes in two engaging posts projected from the outside rose liner. Conventionally, the positioning holes in the door are arranged along a vertical line for use with a typical lockset; yet some door locksets require the positioning holes arranged along a line at an angle of 45° with the vertical line. As a result, a typical lockset cannot be mounted to a door with such positioning holes.
The present invention is intended to provide an improved lockset that mitigates and/or obviates the above problem.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an improved door lockset that has can be mounted to doors with different locations for positioning holes.
In accordance with the present invention, the door lockset comprises three pairs of diametrically positioning holes for use with doors having different locations for positioning holes.
Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

12
with a lock core
13
mounted therein, an outside rose
14
, and an outside rose liner
16
having two engaging posts
18
projected therefrom. Each engaging post
18
has a screw hole
18
a.
The inside handle assembly
20
includes an inside handle
22
, an inside rose
24
, and an inside rose liner
26
having two positioning holes
26
a.
The transmission assembly
50
includes a chassis
54
having two through-holes
52
.
Of more importance, the outside rose liner
16
includes a first pair of diametrically disposed positioning holes
15
a,
a second pair of diametrically disposed positioning holes
15
b,
and a third pair of diametrically disposed positioning holes
15
c,
best shown in FIG.
2
. It is noted that the first pair of positioning holes
15
a
is arranged along a vertical line, the second pair of positioning holes
15
b
is arranged along a line at an angle of 45° (clockwise) with the vertical line, and the third pair of positioning holes
15
c
is arranged along a line at an angle of 45° (counterclockwise) with the vertical line.
As illustrated in
FIG. 1
, a door
32
generally includes a mounting hole
40
for receiving the transmission assembly
50
and a cavity
44
in an end face
34
thereof for receiving the latch bolt
30
. Referring to
FIGS. 1 through 4
, when mounting of the lockset to a door
32
having a pair of vertically arranged holes
42
around the mounting hole
40
, after mounting of the outer handle assembly
10
, two fasteners (e.g., screws
29
) are extended through the through-holes
52
in the chassis
54
and the first pair of positioning holes
15
a
of the outside rose liner
16
, and two other fasteners (e.g., bolts
25
) are extended through the holes
26
a
in the inside rose liner
26
a,
the holes
42
in the door
32
, and the screw holes
18
a
of the engaging posts
18
of the outside rose liner
16
.
Referring to
FIGS. 5 and 6
, when mounting the lockset to a door
32
having a pair of holes
46
that is arranged along a line at an angle of 45° (counterclockwise) with the vertical line passing through the holes
42
in
FIG. 1
, the outside rose liner
16
is turned counterclockwise through 45° until the second positioning holes
15
b
are respectively aligned with the throughholes holes
52
of the chassis
54
. In addition, the inside rose liner
26
is also turned counterclockwise through 45° until the holes
26
a
are respectively aligned with the screw holes
18
a
of the engaging posts
18
. Then, after mounting of the outer handle assembly
10
, two screws
29
are extended through the through-holes
52
in the chassis
54
and the second pair of positioning holes
15
b
of the outside rose liner
16
, and two bolts
25
are extended through the holes
26
a
in the inside rose liner
26
a,
the holes
42
in the door
32
, and the screw holes
18
a
of the engaging posts
18
of the outside rose liner
16
.
It is noted that the lockset in accordance with the present invention can be used with doors of the type having its positioning holes arranged along a line at an angle of 45° (clockwise) with the vertical line.
Provision of the outside rose liner
16
with three pairs of positioning holes
15
a
-
15
c
allows the lockset to be used with different kinds of doors with differently arranged positioning holes.
Referring to
FIG. 2
, the outside rose liner
16
may include a plurality of annularly spaced ridges
17
on an outer periphery thereof such that the ridges
17
are engaged with an inner periphery of the outside rose
14
by press-fitting, thereby allowing joint rotation of the outside rose liner
16
and the outside rose
14
. This allows easy adjustment of the angular position of the outside rose liner
16
. Namely, the user may just turn the outside rose
14
to adjust angular position of the outside rose liner
16
in response to the locations of the positioning holes in the door
32
without the need of detaching the outside rose liner
16
from the outside rose
14
. The inside rose liner
26
includes a plurality of annularly spaced ridges
27
on an outer periphery thereof such that the ridges
27
are engaged with an inner periphery of the inside rose
24
to prevent loosening of the inside rose
24
.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
