Claims priority, al

plication Belgium June 22, 1948 Claims.

My invention has. for its; object to provide painters with variable portable and transform.- able units. whereby the artist is capable of automatically giving. his. panel or canvas the desired height and slope in accordance with any requirements while the artist retains full liberty of execution and his comfort remains very highand approximates that of his studio.

More specifically my invention provides the artist or the amateur either:v

(a) With the possibility of producing a sketch or of painting a picture of. average size through the use of a system comprising chiefly a paint-box the size of which is sufficiently small for it to be carriedv on the knees and associated with means allowing the panel to be, brought to the level of the eyes.

(1)) Inthe case of the artist working outside his studio-or'of an amateur W-hO- has no such studio, with. the possibility of: erectingina few seconds at any point or inanypremises. whatever, say in a. corner of. a room: in a fiat or hotel or the like, a complete and comfortable studio including in. particular a disconnectable easel: for: large-sized canvases: associationwith the paint-box and a. table. or the like support. onwhich. may belaid the palette. and. the like necessary implements.

In order toprovide such. results improvedunit has for its chief feature the provision of a system. of: extensible frames: adapted to hold panelsor canvases or the like of difierent sizes:

In: the practical execution: of the invention, said; arrangement. of extensible: frames includes generally means; for. setting the panel, canvas or the like at a variable height within the desiredlimits, and at an adjustable slope.

The: sliding; of the frames one another is generally executed telescopically.

According. teafirst embodiment of the invention, the extensibleframes. are associated with. a. paint-box of a comparatively reduced size. and. they serve then chiefly for. sketching orta carrier of a comparatively large size.

In a second embodimentthe system. of extensibl'e frames cooperate with means allowing the mounting at any suitablepoint outside a studio of a standard-size studio easel, and the transportation-of the diiferent elements of the-system under. the form of a portmanteau'.

Accompanying drawings showby way of' ex-- ample how the invention may be executed inpractice. In-saicl 'drawings:

Figs. 11 andv 12 illustrate in itsclosed position the portable system containing all the elements tobe used for mounting the easel and thelike accessories-illustrated in Fig. 6*.

In the embodiment illustrated in Fig; 1-, a paint--' box I: is: used. that is: providedas usual witha foldable lid 2 cooperates with a frame 3 provided at each end of its lower cross-me'mber HI with: a lug: 4a engaging a hook side wall of' the. lid 2; thus when engaging the ofi: materialfor'sketche's or a canvas for a painting.

In; the case of'Figs. 2 to- 5, an extensibleframe isaused' that-includes uprights l-2-' constituted eachbya flat member, the Hat members being con nected' together at their upper end by a cross? member t3 and being adapted to slide in grooves l4: formed in the cooperating uprights t5 con necteditogether by a lower cross member M. This extensible frame may occupy positions that are adjustable a's-to height with reference to the fnrther' uprights l7: inside which itmay slide and that. are capable ofrock-ingthroughthe agency of hinges l8 round the ends of the stationany members" .I 9' housed inthe lid 2 at either end. of the. side 20- through which the cover- 2' i's hinged. to. the: paint-box I1 The-uprights FF form thus with the: upper cross member l 7 a frame ofi vaniabler slope with: reference: to. which the lower side or cross member S of the extensible frame may occupy a position that is adjustable as to height.

The stationary members 19 may if required be omitted and in this case the first frame or carrier l1-I 1 is secured through any suitable means allowing the direct pivoting with reference to the side 20 of the lid 2.

The cross-member l6 and the whole system of extensible frames may be held fast at varying positions in a vertical plane through small bolts constituted by rods 2! carried by said cross member, said rods being guided in eyes 22 and being adapted to engage the teeth of racks 23 formed along one side of the uprights l1.

As illustrated in Figs. 2 and 5, this arrangement allows the uprights 12 to pass through the cross member l6.

Fig. 3 illustrates the position occupied when collapsed by the extensible frame l3-l4-l5-l6 and by the uprights 11 when the latter are collapsed inside the cover and lie in alignment with the members is and when the uprights l2 are completely collapsed inside the uprights i5 and the latter inside the members i1-|9.

A feature of interest in the arrangement described consists in that the uprights i1 cannot rock round the hinges it until the frame l3-l2-- l5-l6 has been brought by hand out of the position illustrated in Fig. 3 through a thrust exerted on the cross member 13, after release through the rods 2 l, until a position is reached for which the cross member It lies beyond the hinges it. It is only at this moment that the uprights l1 can be set in a vertical or substantially vertical position as illustrated in Fig. 2 inside which they are held by the stays 2 2 that are capable of rocking round the pivots 25 carried by the uprights i1 and of engaging the notches 25 in the lid 2 as shown in Fig. 2. In each notch there is a stop, not illustrated, adapted to be engaged by the teeth 21 in the stay 2 -5.

It is also possible to provide for a mounting wherein the stay 24 is, as disclosed hereinafter with reference to the rod 53 of Fig. 6, pivotally secured to a nut 55 adapted to slide in a groove 55 of a rule 56 that is in its turn pivotally secured to the edge of the lid.

Figs. 6 to 12 relate to a further embodiment which allows the obtention, at any desired location, of a studio easel (Fig. 6), starting from a compact system assuming the appearance of a portmanteau as illustrated in Figs. 11 and 12; said system includes a plurality of extensible frames adapted to carry different sizes of canvas in any vertical location that may be desired together with supporting forming a table for the palette.

As a system of extensible frames, there are provided three elements of which one 21 forms a complete and rigid frame in the uprights of which may slide slats 28 connected through their lower ends by a cross-member 29 carrying lugs 35 for holding the canvas 3|. In the slats 28 may slide bars 29 connected in their turn by a cross-member 32 carrying lugs 33 for holding the canvas 3| through its upper end. Said cross-member 32 cooperates thus with the bars 29 so as to form a third frame adapted to slide with reference to the frame 28-29 that slides with reference to the basic frame 21.

An orginality of this arrangement consists therefore in that the first frame 21 forms a complete and rigid frame in contradistinction with the embodiment according to Figs. 2 to 5.

The cross member frames and a paint-box 29 carries a small bolt 34 pivotally secured to a 4 adapted to cooperate with a rack 35 extending along the medial vertical line of the frame 21 so as to allow the securing of the frame 28-29 in any desired position as to height.

It is also possible to make use of the securing means as illustrated in Fig. 5.

One of the cross-members of the frame 21 is provided with a. hinge 35 (Fig. 10) arranged so as to allow the pivoting of the system 21--28-29 round a frame 31 of which two parallel sides are provided with longitudinal bores 38 for the sliding feet 39 provided with stop screws 49 adapted to run in rectilinear grooves M.

A box member 43 may be folded through the agency of the hinges 42 inside the frame 31; said box member 43 shows over about of its area a recess 44 adapted to receive the paint-box 55 while the remainder of its area forms a board 46 provided with two slanting grooves #1 inside which may slide securing screws 43 rigid with further feet 59. The frame 31 forms with the box member 43 the actual support for the system of extensible frames which support cooperates with the already described member 5-3-49 allowing the desired suitable slope to be given to said frame.

When it is desired to open the easel, the upper portion of the frame 29 -32 is first slightly raised as obtained by acting through a lock plate 32 on the cross-member 32 the lugs 33 of which hold the members 21-31- 33 and in their locked position.

The frame 21 is now rocked away from the frame 31 through a pivotal movement round the hinge 36; the feet 39 are then drawn out and the feet 19 thereof are drawn out in their turn.

The following operation consists in raising the frame 21 round the hinge S3 in order to bring said frame into a vertical position as illustrated in Fig. 6. The elements 28-29-29 -32 may then be brought into their open unfolded position illustrated in Fig. 5.

The paint box 45 is tality and the two parts 56 of its lid are drawn out into the position illustrated in Fig. 6. The palette 5 or the like implements may be then laid on the unfolded lid 5! as shown in Fig. 6.

It should be noticed that it is possible to rock the paint box 45 with reference to the box member 43 only when the feet 59 have been drawn out because in their retracted position the latter engage the groove 52 to the front of the paintbox.

The arrangement is such also that it is not possible to rock completely the box member 43 without raising the paint-box 35 that rises automatically at the very moment the feet 49 have I been drawn out, as provided by a spring not illusone of the frames 21 or 31. At their ends opposed to the knob 54, the rods 53 are pivotally in grooves 58 formed respectively.

then brought to horizonknob 54 adapted to slidein a groove 55 of a rule 55 pivotally secured to (3) The two half-lids 58 are caused to slide back into their closed position.

(4) The paint-box 45 is urged back into the recess til so as to lock the half lids 50.

(5) The feet 29 are shifted back so as to lock the paint-box inside the said recess 44.

(6) Ihe box member 33 is urged back into the frame 37 of which the feet 39 are collapsed.

(7) The frames 21' and 31 are clamped together and the palette 5i is positioned inside the frame 2'! underneath the lugs (Fig. 12).

(8) The frame 28 32 is pushed home so that its lugs 33 may lock the whole arrangement and close the lock 32 The lugs 39 and 83 (Fig. 6) allow furthermore an adjustment in accordance with the thickness of the panel or canvas, said adjustment being provided through the nuts 30 and 33 (Figs. 8 and 11).

The different parts of the unit described may be made according to the case of wood, metal or the like material. The wood, metal or the like suitable material may also be associated in any desired manner.
