BACKGROUND OF THE INVENTION 
1. Field of the Invention: 
This invention relates in general to board-type educational devices which 
allow indicia to be temporarily drawn. 
2. Description of the Prior Art: 
Chalkboards for allowing numbers, letters and the like to be temporarily 
written or drawn have long been used for educational purposes. Such 
chalkboards can either be fixedly attached to a wall or mounted in a 
movable frame. None of the prior chalkboards or the like disclose or 
suggest the present invention. 
SUMMARY OF THE INVENTION 
The present invention is directed towards improving upon prior board-type 
educational devices which allow indicia to be drawn. The concept of the 
present invention is to provide such a device with means for allowing the 
user of the device to selectively point towards various specific symbol 
indicia means (e.g., letters, numbers, etc.) to aid in various learning 
processes. 
The educational device of the present invention comprises, in general, a 
body member having a substantially flat face surface, and a frame means 
for extending around at least a portion of the periphery of the face 
surface of the body member. The body member has a pointer indicia means 
(e.g., a painted arrow) attached to the face surface thereof and pointing 
towards the periphery of the face surface thereof. The frame means has a 
face surface located substantially adjacent the periphery of the face 
surface of the body member and has a plurality of spaced apart symbol 
indicia means (e.g., painted letters, numbers, etc.) attached to the face 
surface thereof. The body member is rotatable relative to the frame means 
whereby the body member can be selectively rotated to cause the pointer 
indicia means thereof to point towards various specific ones of the symbol 
indicia means of the frame means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
A first embodiment of the board-type educational device is shown in FIGS. 
1-6 and is identified by the numeral 11. The educational device 11 of the 
present invention includes a body member 13 and a frame means 15. 
The body member 13 has a substantially flat face surface 17 and preferably 
has a substantially flat back surface 19. The body member 13 is preferably 
in the shape of a substantially flat, substantially thin disk. The face 
surface 13 and the back surface 19 preferably includes means for allowing 
indicia to be written and/or drawn thereon. Preferably, the body member 13 
is constructed of fiberboard or the like painted on both sides with 
chalkboard surfacing material for allowing indicia to be easily written 
and/or drawn thereon with chalk or the like and with each surface 17, 19 
consisting of one side thereof. A pointer indicia means is attached to the 
face surface 17 in a position so as to point toward the periphery of the 
face surface 17. More specifically, an arrowhead-like mark 21 may be 
painted on the face surface 17 as clearly shown in FIG. 1 substantially 
adjacent and pointing toward the periphery of the face surface 17. 
Preferably, a pointer indicia means is attached to the back surface 19 and 
points toward the periphery of the back surface 19. More specifically, a 
mark 23 similar to the minute hand of a clock may be painted on the back 
surface 19 as clearly shown in FIG. 4. The minute hand-like mark 23 
extends from substantially the center of the back surface 19 to 
substantially the periphery of the back surface 19 and may terminate at 
substantially the periphery of the back surface 19 in an arrowhead-like 
portion. A second pointer indicia means is preferably removably attached 
to the back surface 19 and points toward the periphery of the member 13 
similar to the hour hand of a clock and may be pivotally attached to the 
back surface 19. The hour hand-like member 23 preferably is pivotally 
attached to the back surface 19 substantially at the center thereof and 
extends substantially half way to the periphery thereof as clearly shown 
in FIG. 4. The hour hand-like mark 25 may be pivotally attached to the 
back surface 19 in any manner apparent to those skilled in the art which 
allows the hour hand-like member 25 to pivot relative to the minute 
hand-like mark 23 and stay in any desired position. For example, a small 
block of wood 27 or the like may be fixedly attached to the back surface 
19 of the body member 13 in any manner apparent to those skilled in the 
art such as by glue or the like (see FIG. 6). A screw member 29 may be 
fixedly attached to the block of wood 27 and extends outwardly therefrom 
as clearly shown in FIG. 6. The hour hand-like member 25 may have an 
aperture 31 therethrough adjacent the inner end thereof for allowing the 
hour hand-like member 25 to pass over the screw member 29 as shown in FIG. 
6. A nut member 33 may be screwably attached to the screw member 29 over 
the hour hand-like member 25 to thereby removably attach the hour 
hand-like member 25 to the back surface 19. A spring 35 may be positioned 
between the block of wood 27 and the hour hand-like member 25 as shown in 
FIG. 5 to allow the hour hand-like member 25 to be easily pivoted about 
the screw member 29 when force is applied thereto and to maintain the hour 
hand-like member 25 in a set position when no force is applied thereto. 
The body member 13 preferably includes means substantially spaced from the 
center thereof for use in manually rotating it. For example, at least one 
aperture 37 may be provided through the body member 13 substantially 
adjacent the periphery thereof for reasons which will hereinafter become 
apparent. Preferably a pair of such apertures 37 spaced substantially 
180.degree. apart are provided through the body member 13. 
The frame means 15 has a face surface 39 located substantially adjacent the 
periphery of the face surface 17 of the body member 13. The frame means 15 
also has a plurality of spaced apart symbol indicia means attached to the 
face surface 39 thereof. More specifically, a plurality of letters 41 may 
be painted on the face surface 39 as clearly shown in FIG. 1. For example, 
each letter in the English alphabet may be represented on the face surface 
39, only a representative number thereof being shown in FIG. 1. The body 
member 13 is rotatable relative to the frame means 15 whereby the body 
member 13 can be selectively rotated to cause the arrowhead-like mark 21 
to point towards various specific ones of the letters 41. The apertures 37 
allow the user of the device 11 to easily manually rotate the body member 
13 by inserting a finger, pencil, or the like thereinto. The frame means 
15 preferably includes a back surface 43 located substantially adjacent 
the periphery of the back surface 19 of the body member 13. The frame 
means 15 also preferably includes a plurality of spaced apart symbol 
indicia means attached to the back surface 43 thereof. More specifically, 
a plurality of numerals 45 may be painted on the back surface 43 as 
clearly shown in FIG. 4. The numerals 45 are preferably arranged about the 
back surface 43 of the frame means 15 in the same positions and indicate 
the same numbers as the numerical figures on a clock face. Thus, a 
specific time is indicated when the body member 13 is rotated until the 
minute hand-like mark 23 points towards a specific numeral 45 and the hour 
hand-like member 25 is rotated until it points towards a specific numeral 
45. The frame means 15 is preferably in the shape of a ring and extends 
completely around the periphery of the body member 13. The frame means 15 
preferably has an annular groove 47 therein for trappingly receiving the 
periphery of body member 13 and functioning as a bearing race (see FIG. 
5). Preferably, the frame means 15 consists of a first ring member 49, a 
second ring member 51, and a third ring member 53 attached to one another 
in any manner apparent to those skilled in the art such as by glue or the 
like with the outer surface of the first member 49 forming the face 
surface 39 of the frame means 15 and with the outer surface of the third 
ring member 53 forming the back surface 43 of the frame means 15. The 
second ring member 51 has a larger inside diameter than the first and 
second ring member 49, 53 whereby the groove 47 is formed when the ring 
members 49, 41, 53 are attached to one another as shown in FIG. 5. It 
should be noted that roller bearings or the like (not shown) may be 
provided between the outer edge of the body member 13 and the groove 47 to 
allow the body member 13 to rotate easily relative to the frame means 15. 
The frame means 15 may also include a stand 55 for supporting the body 
member 13 above a supporting surface. The stand 55 may be constructed in 
any manner apparent to those skilled in the art. For example, the stand 
may include a pair of leg members 57 fixedly attached to the ring members 
49, 53 and depending downwardly therefrom, a pair of foot members 59 
attached to the bottom end of the leg members 57 for resting upon a 
supporting surface and a pair of cross members 61 extending from one leg 
member 57 to the other leg member 57. The upper cross member 61 may have a 
groove 63 in the upper surface thereof for acting as a chalk tray and the 
like. The stand 55 may be made adjustable in any manner apparent to those 
skilled in the art to allow the height of the body member 13 above the 
supporting surface to be varied. Also, a seat (not shown) may be mounted 
on the stand 55 to allow the user of the device 11 to sit thereon while 
using the device 11. 
The device 11 may include an eraser means 65 for selectively erasing any 
indicia written and/or drawn temporarily on the face surface 17 or back 
surface 19. The eraser means 65 has a back side 67 and may include a 
magnet member 69 embedded in the back side 67 (see FIG. 3). At least a 
portion of the frame means 15 may be of a magnetically attractable 
material whereby the eraser means 65 can be selectively attached to the 
frame means 15. For example, a piece of iron 71 may be embedded in one of 
the leg members 57 (see FIG. 3). 
The device 11 may be used in various manners which should now be apparent 
to those skilled in the art. For example, the face surface 17 and back 
surface 19 may be utilized in the same manner as a typical blackboard or 
chalkboard to write and/or draw indicia thereon. Additionally, the 
arrowhead-like mark 21 may be utilized to point out various specific 
letters 41 or the like whereupon a child can be asked to duplicate the 
specific letter on the face surface 17, and vice versa, thereby teaching 
the child letters, spelling, writing and the like. Further, the minute 
hand-like mark 23 may be pointed to various specific numbers 45 and the 
child asked to duplicate the specific number 45 on the back surface 19, 
and vice versa, thereby teaching the child numbers and the like. Further, 
the hour hand-like member 25 may be utilized in conjunction with the 
minute hand-like mark 23 in various manners to teach a child how to tell 
time. Various other manners of utilizing the device 11 should now be 
apparent to those skilled in the art.

preferably includes a stand for supporting the body member 2.13 above a 
supporting surface. The stand may include leg members 2.57 fixedly 
attached to the ring member and depending downwardly therefrom. The 
various components of the frame member 2.15 are substantially identical to 
the corresponding components of the frame member 15 of the educational 
device 11 and the above description of the educational device 11 should be 
referred to for a more complete description. However, the groove 2.47 of 
the frame member 2.15 has a first offset portion 2.47' and a second offset 
portion 2.47". 
The educational device 2.11 includes a first insert means 2.73 for being 
selectively positioned on the face surface 2.39 of the ring member of the 
frame member 2.15 (see FIGS. 9 and 10). The first insert means 2.73 
includes a hook-like portion 2.75 for being removably snapped into the 
first offset portion 2.47' of the groove 2.47 (see FIG. 10) whereby the 
first insert means 2.73 is attached to the frame member 2.15 in such a 
manner that allows it to be rotated about the ring member of the frame 
member 2.15. The first insert means 2.73 may include a handle means 2.77 
for use in rotating it about the ring member of the frame member 2.15. The 
first insert means 2.73 is preferably substantially opaque and preferably 
substantially covers any indicia or the like on the face surface 2.39 of 
the ring member of the frame member 2.15. A plurality of spaced-apart 
symbol indicia means 2.79 is attached to the face surface 2.73' of the 
first insert means 2.73 (see FIG. 9). More specifically, each letter of 
the English alphabet and each character of the Arabic numeral system is 
preferably painted on the face surface 2.73' of the first insert means 
2.73. 
The educational device 2.11 may include a second insert means 2.81 for 
being selectively positioned on the back surface 2.43 of the ring member 
of the frame member 2.15 (see FIGS. 7 and 8). The second insert means 2.81 
includes a hook-like portion 2.83 for being removably snapped into the

The device 2.11 may be used in various manners which should now be apparent 
to those skilled in the art. For example, with the first and second insert 
means 2.73, 2.81 removed, the device 2.11 may be used in the same manner 
as heretofore described relative to the device 11. With the first insert 
means 2.73 attached to the frame member 2.15 as shown in FIGS. 9 and 10, 
the device 2.11 may be advantageously used for the teaching of spelling, 
number combinations, and the like. That is, an instructor may ask a 
student to point out the letters of and write a certain work such as, for 
example, "cat." The student can then first rotate the first insert means 
2.73 until the letter "C" thereon is aligned with the mark 2.21, then 
write or draw the letter "C" on the face surface 2.17 of the body member 
2.13 as indicated at 2.87 on FIG. 9, then rotate the first insert means 
2.73 until the letter "A" thereon is aligned with the mark 2.21, then 
write or draw the letter "A" on the face surface 2.17 of the body member 
2.13 adjacent the letter "C" as indicated at 2.87 on FIG. 9, etc. The 
student can be instructed to point out the individual numbers of and write 
a certain number combination in a like manner. With the second insert 
means 2.81 attached to the frame member 2.15 as shown in FIGS. 7 and 8, 
the device 2.11 may be advantageously used for the teaching of angular 
relationships and the like. That is, an instructor may ask a student to 
point out and write a certain angular relation such as, for example, 
"90.degree.." The student can then move the mark 2.25 until the spacing 
between the marks 2.23, 2.25 represent "90.degree." as indicated by the 
indicia means 2.85 on the insert means 2.81, and can then write or draw 
"90.degree. on the back surface 2.19 of the body member 2.13 as indicated 
at 2.89 on FIG. 7. 
Although the invention has been described and illustrated with respect to a 
preferred embodiment thereof, it is not to be so limited since changes and 
modifications may be made therein which are within the full intended scope 
of the invention.
