Description
BACKGROUND OF THE INVENTION
This invention relates to new and useful improvements in
easels.
Easels have heretofore been provided for supporting a canvas or
other blank on which a painting is to be made. The painter in
making the artwork positions himself and his painting arm
selectively to reach the necessary areas of the canvas. It is
difficult and tiring for him to paint in some of the areas of the
canvas such as the upper portions thereof and prior easels have not
made provision for adjusting the canvas in substantially all
positions relative to the painter to make painting easier. Such
easels are thus deficient in this regard.
SUMMARY OF THE INVENTION
According to the present invention and forming a primary objective
thereof, an easel structure is provided which has selected
adjustments facilitating maximum ease of applying the paint on a
canvas supported on the easel.
A more particular object is to provide an easel having a canvas
supporting holder which is rotatably adjustable on its standard so
that the painter can turn the canvas in front of him to more
readily reach all the areas on the canvas.
Another object is to provide an easel of the type described which
has other adjustable means for the canvas supporting holder
facilitating height adjustment to the most convenient place for the
painter and also providing adjustable lateral movement of brackets
on the cross arm to accommodate canvasses of varying sizes.
Still another object is to provide an easel of the type described
having a portion of its structure which is foldable to compact the
unit for convenience in storage and shipment.
The invention will be better understood and additional objects and
advantages will become apparent from the following description
taken in connection with the accompanying drawings which illustrate
a preferred form of the device.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a front elevational view of an easel embodying the
present invention, a canvas or painting backing supported thereon
being shown in phantom lines and the cross arm being rotatably
positioned 90.degree. from its starting or normal position;
FIG. 2 is a side elevational view of the easel in set-up position
for painting;
FIG. 3 is also a side elevational view of the easel but showing it
in folded or compacted condition;
FIG. 4 is an enlarged fragmentary sectional view taken on the line
4--4 of FIG. 1;
FIG. 5 is an enlarged fragmentary sectional view taken on the line
5--5 of FIG. 1; and
FIG. 6 is a fragmentary elevational view taken on the line 6--6 of
FIG. 2.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
With particular reference to the drawings and first to FIGS. 1 and
2, the easel of the invention comprises a standard 10 of board or
plate-like construction secured at its lower end to a cross foot
12. The foot 12 has a rear vertical groove 14 for receiving a
bottom portion of the standard 10, this groove holding the standard
stable in its upright position. A screw 16 holds the foot 12 and
standard together in assembled relation but has a wing nut thereon
for easy removal so that the foot 12 can be removed in storage or
shipment.
A leg assembly 18 supports the standard upright preferably in a
slight rearwardly inclined position. This leg assembly is made up
of three segments, comprising a pair of upright segments 18a and
18b and a bottom rearwardly extending segment 18c. The upper end of
segment 18a has a hinged connection 20 adjacent to the top and on
the rear side of the standard 10. The other end of this segment is
connected to the segment 18b by means of a pair of screws 22
mounted in the segment 18a and extending through an upright slot
24, FIG. 6, in the segment 18b. Slot 24 extends from a point just
short of the upper end of the segment 18b to a point just short of
the lower end thereof. Screws 22 hold the segments 18a and 18b
together but upon loosening them the segments 18a and 18b can be
adjusted lengthwise relative to each other. The lower end of
segment 18b has a hinged connection 26 with one end of segment 18c
and the latter segment has a hinged connection 28 adjacent to the
bottom and on the rear side of the standard 10.
The particular structure of the leg assembly 18 in addition to
providing a desired tilt to the standard 10 is collapsible to a
flat position, such as that shown in FIG. 3 wherein a minimum space
for storage and shipment is consumed. To collapse the leg assembly
from the FIG. 2 to the FIG. 3 position, the screws 22 are loosened
and the links 18a and 18b slid together and the link 18c raised to
lie along the rear side of the standard 10. The screws 22 can be
tightened in this collapsed position of the leg assembly to
maintain such assembly rigidly in collapsed position.
A cross arm 30 is supported on the standard 10 for holding a canvas
C or other picture blank. The canvas or picture blank C is
generally of somewhat rigid material so that it will stand upright,
such usually comprising a canvas with a support backing or a paint
receiving surface which itself is self-sustaining. The cross arm 30
is attached to the standard by a swivel connection 32 comprising a
pair of frictional plates one of which is attached to the rear side
of the cross arm 30 and the other of which is attached to the front
of the standard 10. Attachment of the friction plate to the
standard is accomplished by screws 34 mounted in the said plate and
projecting through upright slots 36 in the standard. By suitable
tightening and loosening of the nuts on screws 34, the cross arm
can be adjusted to various heights on the standard to best position
the canvas according to the desires of the painter. Swivel
connection 32 may comprise any suitable swivel structure but
preferably is of an arrangement which has sufficient friction to
hold the cross arm in place during the painting operation but which
will allow the painter to rotate the cross arm to any adjusted
position.
The cross arm 30 supports a pair of brackets 38 each having a
plate-like body portion 40, FIGS. 1 and 5, bearing against the
front surface of cross arm 30 and having rearwardly extending
flanges 42 disposed on opposite longitudinal edges of the arm and
each having a tongue and groove connection 44 with the cross arm.
The body portion 40 and the flanges 42 are shown as separate pieces
and attachable together by screws 46, but clearly the bracket may
be formed of a single piece. The brackets 38 have slidable
engagement on the cross arm 30, and to provide a set position
thereof on the cross arm they are provided with set screws 48.
These set screws have threaded engagement in a nut 50 embedded in a
rear recess 52 and terminate at their inner ends in enlarged ends
54 adapted to bear on an abutment strip 56 such as metal secured in
a groove 58 in the front face of cross arm 30. Each of the brackets
38 is thus adapted to be anchored in a positive position on the arm
30 by tightening its set screw 48 but is readily adjustable along
the cross arm by loosening the set screw 48.
Each body portion 40 of the brackets has a transverse bar 60
integral therewith, and these bars have lip portions 62, best shown
in FIG. 4, for holding the canvas C on the cross arm.
According to the present invention, the canvas is mounted securely
on the cross arm 30 by clamping it between the bars 60 of the
brackets 38, such brackets being adjustable toward each other for
such purpose. These brackets being adjustable along the entire
length of the cross arm accommodate canvasses of different sizes.
The cross arm 30 may be vertically positioned on the standard to
suit the painter. As the painter progresses with his artwork, the
canvas may be rotatably adjusted to any desired position such as
for example to the FIG. 1 position which is rotated 90 degrees from
the normal or start position of the canvas. Such is merely an
exemplary showing, however, since the cross arm may be rotatably
position to any other degree of rotation according to the desires
of the painter, even upside down.
The canvas is thus capable of being presented to the painter in the
most convenient position to him, namely it can be tilted with the
standard 10, it can be vertically positioned and it can be
rotatably positioned.
It is to be understood that the form of my invention herein shown
and described is to be taken as a preferred example of the same and
that various changes in the shape, size and arrangement of parts
may be resorted to without departing from the spirit of the
invention, or the scope of the subjoined claims.
