Portable easel with adjustable board support

Abstract

A portable easel with adjustable board support which has a plurality of legs pivotally joined together by a head, the legs of which may be selectively spread apart when set up as an easel and folded together when collapsed, each leg composed of multiple interlocked sections biased together when in extended position but which may be manipulated for separation and folding into a bundle one section against another section for storage and transport, and a board support mounted on at least one leg which may be selectively adjustably moved to a desired position on any of the sections and moved against the leg on which it is mounted for storage and transport and extended away from the leg for holding a display on the easel when set up.

Description

This invention relates to a novel portable easel with an adjustable board support, and is more particularly concerned with such a display holding device which is easily and rapidly set up, is capable of adjustably securing a graphic display in a selected position, and which may be selectively quickly collapsed and set up again without special tools or capabilities and which may be conveniently stored and transported in minimum space.

BACKGROUND OF THE INVENTION

Conventional easels usually comprise a tripod or similar arrangement of legs comprised of telescoped tubes or foldable struts which may be extended linearly to a desired height and which have a display support platform across one or more of the tubes or struts, The tubes or struts are usually held in extended position by means of a thumb or set screw or screw collar or similar fastening means locking one tube or strut to the adjacent tube or strut. To collapse the tubes or struts, the thumb screw or screw collar is turned-and one tube is telescoped into an adjacent tube, or the struts are pivotally folded together.

Likewise, the display platform may be adjustable along the tubes or struts and conventionally secured at a desired height by conventional fastening means.

In all known prior art easels, some manipulation of screw-like or similar fastening members is required to lock the easel leg members together linearly. These fastening members require time, space and effort to selectively manipulate them for setting up or collapsing the easel. Frequently, it is necessary to remove the display support platform from the legs or to fold this support or move the support out of its desired display supporting position when collapsing the easel legs, and to reverse the procedure when setting up the easel. Often the display supporting platform must be moved to a selected height when the easel is again set up for use. Usually, the collapsed conventional easel is too bulky to permit it to be carried and stored conveniently, for example, no known full height easel can be carried in a conventional brief case.

SUMMARY OF THE INVENTION

In the present invention, a plurality of sets of tubes or legs (usually preferably three sets) are pivotally connected together at one end or the head of the easel tripod. These sets may be pivotally spread apart, with one end of each set secured to the tripod, to form legs for the easel. Usually, the head includes means for limiting the spread of the legs. Each set of tubes comprises a tripod leg, and each leg is made up of several interlocked sections, preferably telescoped together. Each telescopic section has an end of reduced diameter, and that reduced diameter end is fit interlocked into the other end of the adjacent section.

Within the tubes of each leg is a bungee cord like elastic rope, connected at one end near the tripod head to its adjacent uppermost section and at the other end near the foot of the leg on the last tubular section in the set remote from the head. This elastic rope is under tension, tending to pull the tubular sections together, but still allowing them to be pulled apart by hand manipulative force. When the tubes are folded side to side, the sets are compact and the tube section are not arranged linearly and are separated from one another, forming a bundle of side to side sections. When the tripod head is held and the legs are allowed to fall or shaken in a downward direction, the elastic rope allows each section to swing free and be drawn together telescopically, with the reduced diameter end of one section being drawn home into the open end of the adjacent tube.

A pair of novel display board holders or supports are arranged preferably one each on two of the three tripod legs. This support has two positions: one extended from the leg on which is mounted or a second position folded against the leg on which it is mounted. When extended, the support is locked into position on its leg, and the support is capable of holding a display spanning both like supports at a selected height. When folded, the support is not only compactly arranged and folded against the leg, but also it may be slid along the section of the leg on which it is mounted or onto an adjacent section into another selected position, to the full height of the leg, so that display boards of selected various heights may be handled. These locking, binding and sliding positions for the support depend upon whether nubs or projections on the support engage the leg. The adjacent legs sections must be of a constant diameter to permit the support to be moved upwardly or downwardly from interlocked section to the adjacent section of the leg.

DESCRIPTION OF A PREFERRED EMBODIMENT

With reference to the accompanying drawings, and particularly to FIGS. 1-2 , the portable easel 10 with its adjustable board support 11 embodying the present invention comprises a tripod head 12 which has extending from it several legs 13 , preferably three, and a foot 14 which may be installed on each of the legs.

Each of the legs 13 comprise multiple interlocked telescopic sections 15 . Each leg 13 preferably is pivotally secured to the head 12 by a rivet 16 . The leg 13 can pivot from a position where the legs are aligned side by side to a position where the legs are spread to the position shown in FIG. 2 , limited by the wall 17 of the tripod head 12 .

Except for the upper leg section 15 a one end of which is pivotally secured to the head 12 , each of the other sections 15 b - 15 e has one end 21 which has a reduced diameter and shoulder stop 22 so it will telescope into the other end 18 of each respective adjoining sections 15 a - 15 d . The extreme or bottom end 19 of each section 15 e remote from the head 12 carries the foot 14 to complete each of the legs 13 .

Arranged within each leg 13 is a elastic cord 20 , one end of which is anchored in the upper section 15 a at the head 12 and the other end of which is anchored to the lower leg section 15 e . This elastic cord 20 is under tension drawing the sections 15 a - 15 e telescoped nested together, but the tension is limited so that by hand manipulation, the sections 15 a - 15 e may be disengaged, as shown in FIGS. 1 and 3 , and folded so that the sections 15 may be arranged in a side by side position in the manner shown in FIG. 1 and fully bundled as shown in FIG. 12 .

When folded so that the sections 15 are side by side, the collapsed easel is compact and may be easily placed into a brief case for storage and transport. To erect the easel 10 , it is necessary only to hold the tripod head 12 and shake the sections 15 , in the manner shown in FIG. 1 , where they are telescopically drawn together as extended legs 13 and these legs are pivoted outwardly on the head 12 into the position shown in FIG. 2 .

A board support 11 is preferably mounted on two of the three legs 13 . Each board support 11 has two positions, one where it is folded against the leg 13 on which it is mounted, as shown in FIG. 4 , and one where it is folded away from the leg as shown in FIGS. 2 and 5 . When folded against its leg 13 , the support 11 may be moved upwardly or downwardly along all of the sections 15 a - 15 e of the leg 13 on which it is mounted in the direction of the arrow in FIG. 4 , the sections being of the same constant diameter and smooth and unencumbered when nested telescoped together, as described. When extended from its leg 13 in the direction of the arrow in FIG. 5 , the support 11 is bound in place and will not move, except under substantial pressure, so that it can support a display mounted on it, and the display may be leaned against the leg 13 on which the support is mounted. When in folded position as shown in FIG. 4 , the support will not inhibit folding of the sections side by side into a compact assembly for storage and transport as previously described.

This support 11 comprises a channel-like structure as shown in FIGS. 6-11 , which preferably may be molded from thermoplastic material. This channel-like structure has a bottom wall 30 and spaced apart upstanding walls 31 sized substantially configured to the leg sections 15 . At one end of the support 11 there are a pair of spaced apart upstanding ears 32 , each having a trailing wall 33 intended to prevent a display from slipping off of the support when extended as shown in FIG. 6 . These ears 32 are flexible and together with the cut-outs 34 in the bottom wall 30 adjacent each of the ears as well as inwardly extending nubs 35 on each ear permits each ear to spread slightly and to snap-engage the leg 13 when the support is folded against the leg. The end of the support remote from the ears 32 has a base 36 extending upwardly and angularly disposed from the channel bottom wall 30 and an aperture 37 sized to loosely fit over the leg sections 15 . At opposed positions on the upstanding walls 31 , base 36 extending into this aperture 37 are two sets of projections, an upper pair 39 and a lower pair 40 . The lower rear wall 38 of the base 36 is cut out to permit folding of the support 11 upwardly against its leg 13 . These projections 39 and 40 each snap-engage the leg 13 when the support 1 I 1 is folded fully down to maintain the support in display holding position. The upper wall 38 and lower wall 42 of the base aperture secure the support 11 in rigid position to hold a display. While a preferred embodiment of the invention has been disclosed, many modifications and changes in the structure may be made without departing from the spirit or scope of the invention. Accordingly, it is not desired that the invention should be limited to the exact construction disclosed.
