Description
FIELD OF INVENTION
The invention generally relates to paint applicators and more
particularly with roller-type applicators, and still more
specifically, to an adjustable frame to adjustably journaling
different length rollers.
PRIOR ART
Many types of paint rollers have been contemplated in the past, and
in the art there have been improvements concerning the roller
coverings and the support frames for use with the rollers in
applying paint. The prior art generally has involved a one-hand
manipulated tool having a generally C-shaped holding frame
providing a cantilever shaft upon which a roller of about 10 inches
long is adapted to be journaled. A relatively large and long roller
cannot be supported conveniently and efficiently on a conventional
cantilever rod or shaft of the prior art, since a roller of several
feet in length, and about 4 inches in diameter, when soaked with
paint, is fairly heavy. On the other hand, if the tool, regardless
of weight and dimensions, can be manipulated, more rapid paint
application can be accomplished, clearly affording economies of
reduced time for application and/or labor time, and since the type
paint often applied is relatively "quick-drying," the larger
support frame clearly affords definite advantages and efficiency
not realized in the prior art.
OBJECTS OF THE INVENTION
The primary objects of the invention are to provide an adjustable
support frame providing coaxial support trunnions; to provide a
support frame having a flat, rectangular cross section including
rectangular trackways supporting L-shaped support arms carrying the
trunnions; to provide a support frame as set forth in which the
support arms are oriented to their maximum extended position and
prevented from accidental removal from the frame, in which
retention screws are captivated, and on which orienting indicia are
provided.
These together with other and more specific objects and advantages
will become apparent from a description of an exemplary embodiment
when taken with the drawing forming a part thereof, in which:
IN THE DRAWING
FIG. 1 is a top plan view of a paint roller holder incorporating
the invention;
FIG. 2 is a front elevational view of FIG. 1, showing an alternate
position in phantom lines in relation to a smaller sized roller
also shown by phantom lines;
FIG. 3 is an enlarged vertical section taken substantially on the
plane of line 3-3 of FIG. 1;
FIG. 4 is a cross-sectional view taken on the plane of line 4-4 of
FIG. 3;
FIG. 5 is a view similar to FIG. 4, on a further enlarged scale,
showing the attitude of the retention screw for deforming the
uppermost screw thread to captivate the screw in the frame; and
FIG. 6 is a view similar to FIGS. 1, 4 and 5, showing the parts
after the uppermost frame threads have been deformed.
DESCRIPTION OF AN EXEMPLARY EMBODIMENT
Referring to FIGS. 1 and 2, a paint-applying assembly is indicated
generally at 10 and comprises a support frame 12 to which is
secured a handle 14, and upon which is journaled a paint roller
16.
The handle 14 can comprise wood, metal, plastic etc. The roller 16
will incorporate a conventional paint-retaining cover (as is
conventional), and will include at the opposite ends thereof axial
bore portions (not shown) which can be lined with a metal and/or
plastic bearing sleeve.
The frame 12 includes a crosspiece, base or top member 18 having
secured to the rear edge by rivets 20, a rearwardly angled,
polygonal retention sleeve portion or socket 22 in which the lower
end of handle 14 is suitably secured. The top member 18 is an
extruded channel element; see FIGS. 3--6, and includes an upper web
19 bordered by depending flanges 24 and 26 terminating in inwardly
directed ribs 28 and 30 respectively. The web, flanges and ribs
combine to provide a rectangular, cross-sectioned trackway 32; see
FIGS. 3--6, which is open at the opposite ends 34 and 36
thereof.
Reciprocably and adjustably supported in the trackway 32, are
opposed paint roller support arms 38 and 40, respectively, which
are L-shaped and include an upper plate or leg portion 42 extending
into the open ends of the member 18, and which have depending plate
or arm portions 44 angling inwardly. Secured on the plate portions
44, adjacent the lower ends, are inwardly directed, coaxial
trunnions 46; see FIG. 3, upon which the roller 16 is journaled. It
will be noted that the roller is journaled at both ends, rather
than being cantilever supported, and thus relatively heavy, large
paint-soaked rollers are journaled for rotation in a more stable
arrangement.
The plates 42 have formed thereon indicia 48 and 50 reading "14"
and "18" respectively, indicating the length of the rollers
accommodated in the frame 10 when the indicia 48 and 50 are in
alignment with the respective ends 34 or 36 of member 18. When the
arms 38 and 40 are in the adjusted position shown by phantom lines
in FIG. 2, the shorter roller 16', having a 14-inch length, will be
journaled between the coaxial trunnions 46, and the indicia 48 i.e.
"14," will be aligned with ends 34, 36.
The member 18 has formed adjacent the ends 34 and 36 tapped
apertures 52 and captivated in apertures 52 are knurl-headed
retention screws 54. The screws engage the upper surface of plates
or legs 42 and press them onto the inner surface of ribs 28 and 30
as seen in FIG. 4, for example. The wide legs and rectangular
trackway 32 provide a wide stable base or support for the arms 38
and 40 carrying the heavy roller 16. Formed on the plate portions
42, inwardly of the apertures 52 are projections or abutments 56
which prevent the legs from being accidentally withdrawn from the
trackway 32.
The screws 54 are very substantial, and can be readily adjusted
manually. Attention is called to the lower collar 58 which
initially is driven in the direction indicated in FIG. 5 (with arm
removed) so that the uppermost thread in opening 52 is deformed, by
striking the screwcap while the collar 58 engages the uppermost
thread, thus preventing the screws from being threaded out of the
tapped openings. The axial length of the threaded end 59 is such as
to project into the trackway when thus assembled to engage the
abutments 56 and to resist accidental withdrawal of the arm. It
will be noted that the plates 42, FIG. 6, are engaged at four sides
i.e. on the upper edges of ribs 28, 30, at the sides by inner
surfaces of flanges 24, 26 and at the upper surface by a screw 54,
which is tightened against it. This arrangement permits a single
screw to afford sufficient friction to retain each of the arms in
an adjusted position.
