INVENTOR.

KALAJIAN JOHN f fl r A TTURNE Y5 ADJUSTABLE EASEL This invention concerns an improved artists easel adapted for adjustably supporting a framed canvas and pallette.

Artists easels of the studio type heretofore known have generally been massive structures made of wood with a limited range of adjustability.

The present invention involves a studio type easel which is simpler in construction and more economical to manufacture than prior easels. It is adapted for mounting on a vertical wall or other vertical support, or it can be mounted on a stand for adjustment in various angular positions backward or forward. A pallet is removably and adjustably mounted on the easel. The easel can be made of metal or plastic parts.

Other and further features, objects and advantages of the invention will become apparent from the following detailed description taken together with the drawing, wherein:

FIG. 1 is a perspective view of an easel embodying the invention.

FIG. 2 is a reduced side view of the easel with pallet attached.

FIG. 3 is a fragmentary enlarged sectional view taken on line 3-3 ofFlG.1.

FIG. 4 is an exploded perspective view of parts of the easel.

FIG. 5 is an enlarged perspective view of the palette per se.

FIG. 6 is a perspective view of another easel including a stand for adjustable angular support.

FIG. 7 is a side view illustrating how the easel can be angularly adjusted.

FIGS. 8, 9 and are enlarged fragmentary sectional views taken on lines 8-8, 9-9 and 10-10 of FIG. 6.

FIG. 11 is an exploded perspective view of parts of the easel of FIG. 6 and FIG. 7.

FIG. 13 is a further enlarged cross sectional view taken on line 13-13 of FIG. 12.

FIG. 14 is a fragmentary enlarged cross sectional view taken on line l4- 14 of FIG. 6.

Referring first to FIGS. 1-4, there is shown an easel mountable on any suitable vertical support such as a wall 22. The easel comprises a pair of vertical parallel channel bars or

rails

23 and 24 each having a back wall 25, side walls 26 and front flanges 28 separated by a longitudinal slot 30. A pair of upper and

lower angle bars

32, 34 is provided for supporting a rectangular framed stretcher frame 36 on which a canvas. Bar 32 has a vertical flange 38 provided with spaced holes 40 through which extend carriage bolts 42. The head 43 of each bolt is engaged on a shoulder in hole 44 formed in a clamp block 46 slidably disposed inside one of the

rails

23, 24. The shank of the bolt extends through slot 30 and is engaged by wingnut 48 and washer 49; see FIGS. 3,4. A flange 50 is angularly disposed to flange 38 and extends forwardly and downwardly to engage the top of frame 36. A similar arrangement of clamp block, carriage bolts and wingnuts is provided for the lower bar 34. Bar 34 has a flange extending outwardly and upwardly from vertical flange 62 for engaging and supporting the lower end of framed canvas 36.

A palette is provided for the easel. This palette has a horizontal platform 72 provided with a vertical back wall 74. Secured to the back wall is a bracket 75 having forwardly extending spaced fingers 76 arranged to engage capped tubes 77 of paint or other materials employed by an artist in painting on the canvas 36. The platform has an opening 78 for supporting a container 79 of turpentine or other fluid. The palette can be secured to rail 34 by inserting ends of bolts 40 through holes 80 provided at upper corners of back wall 74 and bracket 75.

By the arrangement described,

bars

32 and 34 can be adjustably spaced apart vertically for mounting canvas covered frames of different sizes. The palette 70 moves up or down with bar 34 so that it is always conveniently placed for use. The palette can easily be removed if desired. The

vertical rails

23, 24 can be secured to vertical support 22 by means of screws or bolts 82 inserted through holes 83 in back wall 25 of each rail. Further holes 84 can be provided at bottom ends of the rail for purposes described in connection with FIGS. 613 to which reference is now made.

The easel 20A shown in FIGS. 6 and 7 is generally similar to easel 20. and corresponding parts are identically numbered. A stand is provided to support the easel frame. The stand includes cross bar 90 inserted between

bars

32, 34 and held in place by bolts 92 inserted through slots 30 in the

vertical rails

23, 24. The bolts are engaged in slidable clamp blocks 94 in

rails

23, 24; see FIG. 8. Pivotally engaged on bracket 96 secured to the back of bar 90 is the upper end of a brace bar 98. This brace bar is channel shaped; see FIG. 10. Opposed flanges 97 of bar 98 are engaged by hinge bolt 99 extending through sleeve 102 and engaged by wingnut 106. Bar 98 is pivotally engaged at its lower end by bolt 108 in bracket flanges 110 on cross bar 112; see FIG. 14. The lower ends of

rails

23, 24 are engaged by bolts 114 inserted through holes 84 in

rails

23, 24, sleeves 115, and slots 116 in spaced flanges 118 of channel bars 120; see FIGS. 9, 11. Forward ends of the bars 120 extend beyond the slots 116. The base bars 120 are joined by cross bars 112, 122. Bolts 114 are held by wingnuts 126. By the arrangement described, the

rails

23, 24 can be adjusted in various selected angular positions with respect to the horizontal channel bars 120, as shown by dotted lines in FIG. 7. The forwardly tilted position P shown in FIG. 7 is desirable when a canvas on a large stretcher 36' is being painted and it is desired to reach upper parts of the canvas without smearing lower parts. The rearwardly tilted position P' is desirable for painting small pictures.

Palette 70a shown in FIGS. 7, 12 and 13 has a back wall 74a provided with apertured ears 128 for receiving bolts 42 held by wingnuts 48 at angle bar 34. The palette has an upper forwardly tilted flange 130 which abuts the underside of flange 60 on bar 34. This stabilizes the structure. On back wall 74a are integrallyforrned channel guides 132 and 133 which slidably receive

plates

134 and 136. Plate 134 is formed with fingers 138 for holding tubes of paint. This plate has a cross head 140 engaged in channel guide 132. Plate 134 is angularly disposed to back wall 74a as best shown in FIG. 12 so that when the easel is tilted forwardly to position P as shown in FIG. 7, the tubes 77 will be held upright. Lower channel guide 133 removably supports palette plate 136. Plate 136 is provided with a cross head 144 which fits slidably in the channel guide.

By use of stand 100, the easel frame can be supported on a floor or other horizontal support and can be tilted at various angles for optimum convenience in painting. When not in use the stand can be folded up behind the easel frame formed by the vertical rails and cross bars.

The rails of the ease] can be made of extruded metal or plastic parts. Other parts can also be made of metal or plastic. The easels are light in weight, strong and durable in construction, and can be economically manufactured. They will not crack, chip or warp. They are dimensionally stable. They can be made up in attractive colors and different sizes, which can provide means for mounting and displaying paintings and pictures.

While a limited number of embodiments of the invention have been described, it will be apparent that many modifications are possible without departing from the invention.
