Sep t. 5, 1967 L. KERSTENS EASELS Filed Aug; 5, 1965 I NVENTOR. 1m" lfz/Jzem BY MMM United States. Patent Q 3,339,874 EASELS Leif Kerstens, 3 Jeppe Aakjaersvej, Aabyhoj, Denmark Filed Aug. 5, 1965,Ser. No. 477,386 2 Claims. (Cl. 248-463) ABSTRACT OF THE DISCLOSURE The invention relates to an easel having an easily movable base plate and means for releasably holding a cross bar holding a bunch of paper sheets containing the informative material to be demonstrated. The invention specifies the manner in which the cross bar holds the paper and is held releasable on the said base plate.
The present invention relates to a teaching or illustrating device of the easel type, comprising an upright frame having adjacent the top thereof means for releasably holding the top portion of a pad of paper sheets hanging down therefrom. The paper sheets are prepared with the desired informative matter, and during a lecture or address the lecturer may show the different illustrations to the audience by successively swinging the single sheets over the top edge of the frame and down at the rear side of the frame to thereby uncover the next paper sheet in the pad.
Usually, each pad of paper sheets contains illustrative matter for a specific lecture object, and thus it is desired to have a possibility of archivating the different pads. Furthermore, the frames should be easily movable.
One object of the present invention'is to provide an easel in which means are provided for facilitating the operation of interchanging different sheet pads in the frame.
A further object of the invention is to provide an easel in which the holding means referred to are adapted to cooperate with separate suspension means 'for the top edge of the sheet pad in order to make the suspension means including the paper sheets easily releasable from the holding means and correspondingly easilymountable in and removable from the archives. 1 r
Still a further object of the invention is to provide an easel in which the"'su'spension means are of simple and cheap construction and designed to cooperate with cor;- resporidingl'y simple holding means on the frame and simple carrying means in the archives.
A still further object of "the. invention is to provide an easel adapted to stand on a surface such as a table in a stable manner, the frame being providedwith a staylegwhich is easily moved between a completely stable'stay position and a position in which it is packed together with the frame in order to allow the frame including the stay leg to be tightly packed for transport and storage.
Another object of the invention is to provide an easel, the supporting legs of whichincluding the stay leg-are adjustable in order to allow the holding means for the sheet pad to assume a desired height above the supporting surface.
These and other objects and advantages will appear from the following description, reference being made to the accompanying drawing, in which:
FIG. 1 is a perspective view of a preferred embodiment of an easel according to the present invention, seen from the front side, and
FIG. 2 is a corresponding view of the easel seen from the rear side.
The easel shown in the drawing comprises a frame 2 having a transverse top portion 4 and a pair of cross rods 5 (FIG. 2). The lower ends of the frame 2 are provided with tip cups 3. A plate member 6 is mounted inside the 3,339,874 Patented Sept. 5, 1967 'ice mounted in the manner to be described below.
Adjacent the top portion 4 the frame 2 is at each side provided with carrying brackets 10 adapted to releasably receive laterally protruding portions 11 of a cross rail or plate 12. Preferably the brackets 10 are made from resilient material such as spring steel and dimensioned so as to hold the rail portions 11 pressed against the frame por tions therebehind.
The cross plate 12 is at the front side thereof provided with a clamping member 14 having an upper edge portion 15 bent inwardly to engage the front surface of the plate member 12. To the clamping member 14. there is secured a pair of bolts extending rearwardly through holes in theplate 12 and adjacent the rear side thereof provided with finger screws 16. It will be understood that the clamping member 14 will be tilted around its upper edge and drawn towards the plate 12 when the screws 16 are tightened. Between the clamping member 14 and the. plate member 12 there is inserted the top edge portion of a pad 18 of papersheets or sheets of another suitable material capable of having written, printed, formed or otherwise depositedthereon such informative characters, pictures, etc., that are.
2 as indicated with dotted lines in-FIG. 1. In this manner:
he can successively uncover and expose all the sheets.
After the use the'entire pad 18 of information sheets may be lifted up fromthe brackets '10 togetherwiththe plate and clamp members 12 and 14, and this unit may thereafterbe placed in holding means in an-archive among other similar unit's. Due to, the laterally protruding portions '11 of the plate 12the unit may simply be hanged crosswise on two parallel rails in the archive, so that no special installation apart from two ordinary rods will be required for this purpose. In order to guide the units on such rods in the archive the underside of the portions 11 may advantageously have a configuration corresponding tfo-the cross section of the upper part of the rods for example a round recess for resting on a cylindrical rod in'an archive. It will be noted that the sheet pads may be easily put down and taken up between sucha pair of archive rods.
The plate 6 between the side portions of the frarne Z; is preferably made as a so'called flannel table, i.e. a plate surface covered by flannel or a similar material enabling cut out pieces of felt or similar material to be held on the flannel surface when pressed thereagainst even in vertical position of the table. Such tables per se belong to the known art, but it will be appreciated that the use in an easel of such a table as a backing means for the sheet pad is particularly advantageous since the easel may then be used alternatively as a flannel table, i.e. there will be no need for schools etc. to procure special flannel table units when they work with easels according to the invention.
The stay member 8 has a triangular form, one side 20 of which is mounted slidable and turnable in the tube 22 referred to herein before. The stay member side 20 preferably consists of the outer ends of a rod from which the stay member is made by bending the rod, said end extending some distance into both ends of the tube 22.
Adjacent its lower end the tube 22 is provided with a vertical slot 24 of a breadth corresponding to the thickness of the stay member rod. Along the edges of this slot there is mounted a bent edge rib 26 having branch 28 extending downwardly beyond the end of the tube 22 and an opposite branch 29 extending a shorter distance down from the top edge of .the slot 24. When the stay member side 20. is assuming a lowermost position on the tube 22, wherein the top bend of the stay member 8 res-ts against the top edge of the tube 22, the lower side 9 of the stay member is situated beneath the lower edge of the tube 22 and beneath the lower end of the rib branch 29 but in level with the lower end portion of the rib branch 28. In this position which is shown in full lines in FIG. 2 the stay member 8 will be free to be swung around the side 20 out to a position shown in dotted lines in which it may be releasably arrested by means of a spring member 30 secured to the frame and cooperating with the outer bend of the stay member. In this position the stay member is situated quite close to the plane of the frame so that the easel will have small space requirements when stored or transported.
When the easel is wanted to be used the stay member 8 is pulled out of engagement with the spring member 30 and swung outwardly until it is stopped by the rib branch 28. From this position-again corresponding to the position shown in full linesthe stay member 8 is lifted up to the position shown in dot-and-dash-lines in which the lower stay member portion 9 is lifted up into the slot 24. This lifting may be caused simply by placing the easel in the desired position on a table and letting it tilt slightly backwardly whereby the stay member will automatically be lifted in the tube 22. It will be seen that the stay member will be completely stable in this last mentioned position of use, since it will be locked between the two rib portions 26 and 29 as long as the easel is standing on the table. However, it is easy to release from this position as soon as the outer end of the stay member is lifted from the table.
This arrangement is very simple to operate, cheap to manufacture, and durable in use. The tube 22 need not necessarily have a slot 24, since it may end adjacent the upper portion of the rib member 26 as indicated by a dotted line, whereby the slot 24 will be formed by the rib branches 28 and 29 extending downwardly from the end of the tube 22.
The side portions of the frame 2 may consist of tubes enclosed therein a downwardly protruding rod carrying at its outer end the tip cup 3. Screws of which one is shown in dotted lines in FIG. 1 and designated with 17 may serve to hold the rods in a desired position in the frame 2, whereas the. rods as shown in dotted lines in FIG. 1 may be pulled out telescopically from the frame and fixed in any position by means of the screws 17 so that the frame may be height adjusted relatively to its supporting surface. A similar arrangement may be provided in the rear part of the stay member 8, where a rod 19 shown in dotted lines in FIG. 1 may be pulled telescopically out from the rear stay member branch through a hole situated in alignment with an interior cylindrical passage therein. Since also the lower branch of the stay member is inclined, the arrangement may alternatively be provided with this branch.
