Claims
What I claim is:
1. A paint roller assembly comprising: a support shaft including a
cantilever supported, paint applying roller journaled for rotation
about its longitudinal axis; and a handle including means
integrally connecting the lower end of said handle in
longitudinally extending relation from the upper end of said
support shaft,
said handle being tubular and including a rearwardly opening
socket,
said socket including means for removably connecting an auxiliary
handle substantially balancing the roller assembly about said
handle,
said handle having opposed sides extending longitudinally and
having intermediate, longitudinally extending indentations for
orienting a user's finger tips when the handle is gripped, said
sides and indentations being disposed in a plane substantially
normal to the axis of rotation of the cantilever supported roller,
opposite sides of the handle at substantially 90.degree. to the
indented sides having a plurality of longitudinally spaced finger
accommodating undulations for further orienting a user's fingers
and conveniently and comfortably accommodating one's hand.
2. The structure as claimed in claim 1 in which an auxiliary handle
is removably disposed in said axial socket.
3. The structure as claimed in claim 2 in which said means
comprises cooperating, threaded socket and stub shaft portions on
said molded and auxiliary handles.
4. The structure as claimed in claim 1 in which said handle
includes at least one outwardly opening, transverse notch portion
opening toward said roller and parallel to the axis of rotation
thereof for permitting the assembly to be hung on the edge of a
support.
5. The structure as claimed in claim 5 including a second outwardly
opening, transverse notch parallel to said first-mentioned one
whereby the assembly can be hung on the inside or outside of a
support edge such as a paint bucket or the like.
6. The structure as claimed in claim 1 in which said
cantilever-supported roller is eccentric relative to an axial
projection of the longitudinal axis of the support shaft and having
a major portion projecting laterally and outwardly beyond said
axial projection to substantially balance the roller about said
longitudinal axis.
7. A paint roller as set forth in claim 1 wherein said handle
includes a skirt portion extending longitudinally from the handle
remote from said support shaft, an auxiliary handle removably
secured in said handle socket, said skirt portion surrounding said
auxiliary handle and in spaced relation therefrom and defining a
protective hood at the juncture of said handle and said auxiliary
handle when in assembly.
8. In a paint roller assembly comprising a support shaft including
a paint applying roller journaled for rotation about its
longitudinal axis; and handle means including means integrally
connecting the lower end of said handle in longitudinally extending
relation from the upper end of said support shaft, the improvement
comprising:
said handle being tubular and including a rearwardly opening socket
including means for removably connecting an auxiliary handle for
substantially balancing the paint applying roller about said
handle, said handle having opposed sides extending longitudinally
and having intermediate, longitudinally extending indentations for
orienting a user's finger tips when the handle is gripped, said
sides and indentations being disposed in a plane substantially
normal to the axis of rotation of the roller, opposite sides of the
handle at substantially 90.degree. to said indentations having a
plurality of longitudinally spaced finger accommodating
indentations for further orienting a user's fingers.
Description
Applying paint by means of rollers is well known in the art,
however, containers for holding the paint being applied have
comprised a relatively flat, angular-bottomed tray. The use of this
type container generally results in an excessive use of paint.
Further, although it is alleged that paint rollers can be more
readily used to apply paint than through the use of conventional
brushing, however, the rollers are relatively heavy and use of a
roller over a long period of time can cause fatigue to an
inexperienced workman. Additionally, roller type applicators are
manipulated in one hand and this rapidly tires the user.
Primary objects of the present invention are to provide a novel
paint roller type paint applicator which includes an improved
handle construction;
To provide a novel handle for a roller type paint applicator in
which means are provided to hand the applicator on the edge of a
support;
To provide a novel handle on a roller type paint applicator which
includes a hand-conforming portion and in which an axial socket
permits an auxiliary balancing extension-handle to be detachably
connected to the molded handle permitting two-handed
energy-conserving use of the applicator.
These, together with other and more specific objects and advantages
of the invention, will become apparent from a consideration of the
following description of an exemplary embodiment when taken in
conjunction with the drawing forming a part thereof, in which:
In the drawing:
FIG. 1 is an elevational view of the novel roller type paint
applicator;
FIG. 2 is a side view of FIG. 1, showing by phantom lines a
fragmentary portion of a paint bucket edge upon which the
applicator can be hung; and
FIG. 3 is an enlarged, fragmentary section taken on the plane of
line 3-3 of FIG. 2.
Referring to the drawing, a roller type paint applicator is
indicated generally at 10 and comprises a support shaft 12 integral
with a C-shaped portion 14 having a lateral shaft (not shown in
detail) upon which a cantilever roller 16 is journaled. The roller
is of any suitable material and will generally be of the replacable
type. The roller is balanced with respect to the longitudinal axis
A of the support shaft, it being noted that portion x of the roller
is less than portion y of the roller i.e. the roller is eccentric
relative to the shaft axis A.
The shaft 12 includes one or more longitudinal grooves 18 at the
other end, and molded and integrally connected to the shaft 12 and
overlying the grooves 18 is a tubular handle 20. The handle 20 is
elongated and preferably molded from a suitable plastic, including
open ended grooves 22 at its inner end which open toward the
roller, longitudinal concavities as seen at 24 and spaced
undulations 26 at substantially 90.degree. to the concavities. As
seen in FIG. 2, the hooks 22 conveniently permit the roller
assembly to be hung on either the outer or inner side of a bucket
edge containing paint, or on any other convenient support.
The handle, as seen in FIG. 3, opens axially and includes a
recessed, threaded bore 27; having relatively coarse threads, and
into which a correspondingly threaded end 28 of an elongated
auxiliary handle 30 is removably secured. The handle 30 in most
instance will be of a length of about 15 inches, for example, and
this permits paint to be applied to the walls, for example, with
the painter using both hands i.e. one hand grasps the handle and
the other grasps the auxiliary handle 30. In effect, the roller
assembly is balanced about the handle 20 and the heavy
paint-saturated roller is comfortably balanced in the user's two
hands, and paint can be applied over a much longer period of time,
without becoming tired, than is possible with conventional rollers
held in only one hand.
Additionally, if preferred, the handle 30 can include an extensible
section utilizing the teachings of applicant's U.S. Pat. No.
3,259,407 related to locks for telescopic tubes; in this instance
the auxiliary handle 30, if extensible, permits ready painting of a
ceiling or a high place without the use of a ladder. Of course, the
auxiliary handle can comprise an integral pole of any convenient
length and permit the roller to be readily used for painting
ceiling etc. still affording the previously mentioned, balanced,
two-handed construction.
In the preferred embodiment a skirt 32 is provided on the end of
the molded handle in circumposed relation about the adjacent end of
the extension handle 30 and in spaced relation therefrom to provide
a protective hood enclosure 34 to prevent drops of paint from
encrusting upon the connecting thread area and which skirt also
serves to separate the rim 36 of the skirt from the outer surface
of the extension handle as it is flexed in use, thus prolonging the
appearance of the handle at this wear point and resisting fraying,
weakening, or rupturing of the handle, such as by stress risers
extending longitudinally of the molded handle, to this end, the end
of the extension handle is radiused as at 38 to smoothly join the
molded portion.
