4 SUMMARY OF THE INVENTION
The portable chartholder and table is a naviga-6 tional aid or device consisting of two flat, i.e., planar 7 rigid planar members held together with at least one mem-8 ber transparent for viewing and separable, by means of 9 manually operable securing and release mechanisms. Any 10- nautical, aeronautical, or surface chart, map, diagram 11 or other graphic material, may be inserted between the 12 viewing members, and will be held flat and stationary.
13 Because both planar members can be transparent, both sides 14 of any material held between the viewing members-are im-mediately viewable by simply turning the invention over 16 and viewing its opposite side. This also allows ~or the 17 insertion of material between the viewing members on a 18 back to back basis, or folded, and permits maximum expo-19 sure through both viewing members, with each viewing mem-ber immediately accessible by simply turning the invention 21 over onto its opposite side. Although it is pre~erred to have 22 both planar members transparent so the enclosed chart can 23 be read on both sides as noted it is neces~y only to have 24 at least one planar mem~er \transparent for viewing the enclosed chart, map or other flexible document.
26 Courses and distances may be calculated and plot-27 ted on at least one of the viewing surface members with 28 any ordinary "china marker", grease pencil or similar mark-29 ing device. Such markings on the viewing member may be removed and erased with any ordinary paper tissue, paper 31 towel, or piece of cloth. Once such markings are removed, 32 the surface of the viewing member remains clear and trans-33 parent, and new or corrected courses and distances may be 34 calculated and plotted.
The chartholder is protected against breakage of 36 its own parts and against damaging or breaking other ob-37 jects with which it might come into contact if dropped or ~iS7~
1 thrown about in heavy seas, air turbulence or the like.
2 This protection is provided by cushioning devices located 3 around and extending out beyond the peri~eter of the invention.
4 The chartholder has flexible, removable grab S handles which facilitate grabbing, lifting, moving, and 6 carrying the invention about.
7 The invention is therefore embodied in a portable 8 chartholder and table comprising two rigid planar members 9 at least one of which is transparent, secured together by manually operable securing means having a release mech-11 anism, at least one flexible grab handle connected to at 12 least one of said planar members and multiple cushioning-13 supporting means secured on the perimeter of said planar 14 members, said planar members cooperating in a manner where-by a chart can be positioned contiguous with an inner sur-16 face of each of said planar members and readily read by 17 the helmsperson of a moving boat.
18 It is preferred that both rigid planar members 19 are transparent. Further, it is preferred that each of said cushioning-supporting means have a slip-resistant ex-21 terior concave surface with a hollowed out center which 22 fully envelop and accomodate the portions of said securing 23 means exterior of the surface of said Planar member and that 24 said cushioning-supporting means are of a cushioning material and extend out beyond the perimeter of the secured p~r m~a~s.
27 For a fuller understanding of the nature of the 28 invention, reference should be made to the detailed de-29 scription taken in connection with the accompanylng draw-in~ in which:
31 Figures 1 and 2 are top and bottom plan views of 32 an assembled portable chartholder and table;

2 The portable chartholder and table is a naviga-3 tional aid or device. It consists of two flat, rigid, 4 transparent viewing surfaces, held together, and separable, by means of manually operable securing and release mecha-6 nisms. As shown in Figures 1 and 2, the viewing plan~r 7 members 10 and 11 are transparent, and fit onto each other 8 by alisning their respective edges 12 and 13, i.e. perimeters with each g other. The viewing members 10 and 11 also contain~holeS
which pass through them, and through which pass the manual-11 ly operable securing and release mechanisms. Figure 3 and 12 Figure 4 show the holes 14and'the manually operable secur-13 ing and release mechanisms 16~which pass through them. The 14 holes 14 through each viewing member 10 and 11 align with each other in order to allow the securing and release mecha-16 nisms to secure the flat, rigid transparent planar members 17 10 and 11 to each other. They also secure at the perimeter 18 of the viewing members 10 and 11 slip resistent supporting 19 and cushioning devices 15. Each of these devices 15 extends out beyond the perimeter and has a hole thrPugh 21 its center to allow passage of the manually operable secur-22 ing and release mechanisms 16 whichare shown here as -23 threaded thumbscrewsl7 and nu~ 18. The mechanisms 16 then 24 not only secure the viewing surfaces together, but secure the slip resistent supporting and cushioning devices 15 26 to the viewing surfaces. Figure 4 shows an exploded side 27 view of the chartholder and table and the relationship of 28 the aforementioned parts to each other. Figure 3 shows a 29 side view of the assembled chartholder and table showing the relationship of the aforementioned parts to each other 31 when the chartholder and table is in its secured position.
32 The slip resistent supporting and cushioning devices 15 33 also have hollowed out centers which fully envelop and 34 accomodate the portions of the manually operable securing and release mechanisms 16 which extend above and out from 36 each viewing surface. This may be seen in Figure 1, Figure 37 2 and Figure 3. This prevents the securing and release . :

Any 10- nautical, aeronautical, or surface chart, map, diagram 11 or other graphic material, may be inserted between the 12 viewing members, and will be held flat and stationary.
13 Because both planar members can be transparent, both sides 14 of any material held between the viewing members-are im-mediately viewable by simply turning the invention over 16 and viewing its opposite side.

Although it is pre~erred to have 22 both planar members transparent so the enclosed chart can 23 be read on both sides as noted it is neces~y only to have 24 at least one planar mem~er \transparent for viewing the enclosed chart, map or other flexible document.
26 Courses and distances may be calculated and plot-27 ted on at least one of the viewing surface members with 28 any ordinary "china marker", grease pencil or similar mark-29 ing device. Such markings on the viewing member may be removed and erased with any ordinary paper tissue, paper 31 towel, or piece of cloth. Once such markings are removed, 32 the surface of the viewing member remains clear and trans-33 parent, and new or corrected courses and distances may be 34 calculated and plotted.
The chartholder is protected against breakage of 36 its own parts and against damaging or breaking other ob-37 jects with which it might come into contact if dropped or ~iS7~
1 thrown about in heavy seas, air turbulence or the like.
2 This protection is provided by cushioning devices located 3 around and extending out beyond the peri~eter of the invention.
4 The chartholder has flexible, removable grab S handles which facilitate grabbing, lifting, moving, and 6 carrying the invention about.
7 The invention is therefore embodied in a portable 8 chartholder and table comprising two rigid planar members 9 at least one of which is transparent, secured together by manually operable securing means having a release mech-11 anism, at least one flexible grab handle connected to at 12 least one of said planar members and multiple cushioning-13 supporting means secured on the perimeter of said planar 14 members, said planar members cooperating in a manner where-by a chart can be positioned contiguous with an inner sur-16 face of each of said planar members and readily read by 17 the helmsperson of a moving boat.
18 It is preferred that both rigid planar members 19 are transparent.

27 For a fuller understanding of the nature of the 28 invention, reference should be made to the detailed de-29 scription taken in connection with the accompanylng draw-in~ in which:
31 Figures 1 and 2 are top and bottom plan views of 32 an assembled portable chartholder and table;

2 The portable chartholder and table is a naviga-3 tional aid or device. It consists of two flat, rigid, 4 transparent viewing surfaces, held together, and separable, by means of manually operable securing and release mecha-6 nisms. As shown in Figures 1 and 2, the viewing plan~r 7 members 10 and 11 are transparent, and fit onto each other 8 by alisning their respective edges 12 and 13, i.e. perimeters with each g other. The viewing members 10 and 11 also contain~holeS
which pass through them, and through which pass the manual-11 ly operable securing and release mechanisms. Figure 3 and 12 Figure 4 show the holes 14and'the manually operable secur-13 ing and release mechanisms 16~which pass through them. The 14 holes 14 through each viewing member 10 and 11 align with each other in order to allow the securing and release mecha-16 nisms to secure the flat, rigid transparent planar members 17 10 and 11 to each other. They also secure at the perimeter 18 of the viewing members 10 and 11 slip resistent supporting 19 and cushioning devices 15. Each of these devices 15 extends out beyond the perimeter and has a hole thrPugh 21 its center to allow passage of the manually operable secur-22 ing and release mechanisms 16 whichare shown here as -23 threaded thumbscrewsl7 and nu~ 18. The mechanisms 16 then 24 not only secure the viewing surfaces together, but secure the slip resistent supporting and cushioning devices 15 26 to the viewing surfaces. Figure 4 shows an exploded side 27 view of the chartholder and table and the relationship of 28 the aforementioned parts to each other. Figure 3 shows a 29 side view of the assembled chartholder and table showing the relationship of the aforementioned parts to each other 31 when the chartholder and table is in its secured position.
32 The slip resistent supporting and cushioning devices 15 33 also have hollowed out centers which fully envelop and 34 accomodate the portions of the manually operable securing and release mechanisms 16 which extend above and out from 36 each viewing surface. This may be seen in Figure 1, Figure 37 2 and Figure 3. This prevents the securing and release . :

7 ~he slip resistent supporting and cushioning de-
8 vices, when secured to the viewing surfaces by the secur-g ing and release mechanisms, themselves extend out beyond the perimeter of the viewing surfaces. This may be seen in 11 Figure ~ and Figure 2. This extension of the slip resistent 12 supporting and cushioning devices 15 provides a perimeter 13 cushioning and shock absorbing mechanism. In this fashion, 14 the supporting and cushioning devices 15 prevent the flat rigid transparent surfaces from causing damage, and from 16 being damaged themselves, if the chartholder and table 17 is dropped, or tossed or thrown about by the operation of 18 wind, water or other forces in rough going on any vessel, 19 vehicle, aircraft or other conveyance where the ~ortable chartholder and table may be in use. This is particularly 21 significant in the case of use on fiberglass boats, where 22 the fiberglass structural material in the cabin or cock-23 pit would be subject to being scratched, chipped, or crack-24 ed by contact from any chartholder or table not so cushion-ed or protected.
26 The portable chartholder and table is also fitted 27 with flexible grab handles 19 and 20 on two of its sides.
28 This is illustrated in Figures 1 and 2. These flexible 29 grab handles 19 and 20 are secured by having ~he manuall~
operable securing and release mechanisms 15 pass through 31 loops 21 and 22 at the outermost end of each such flexible 32 grab handle. The loops 21 and 22 on the ends of the flex-33 ible grab handles 19 and 20 fit onto the viewing members 34 over the holes in the planar members through which pass the securing and release mechanisms 15. The slip resistent 36 supporting and cushioning devices 16 fit over the afore-37 mentioned end loops 21 and 22 on the grab handles 19 and 20 bL~*Z

Figure 4 illustrates the relationship between the component parts 6 herein mentioned and shows the flexible grab handles 19 7 and 20 as described. These grab handles 19 and 20 facili-8 tate grabbing, lifting, moving and carrying the invention
26 The portable chartholder and table is also fitted 27 with flexible grab handles 19 and 20 on two of its sides.
28 This is illustrated in Figures 1 and 2. These flexible 29 grab handles 19 and 20 are secured by having ~he manuall~
operable securing and release mechanisms 15 pass through 31 loops 21 and 22 at the outermost end of each such flexible 32 grab handle. The loops 21 and 22 on the ends of the flex-33 ible grab handles 19 and 20 fit onto the viewing members 34 over the holes in the planar members through which pass the securing and release mechanisms 15. The slip resistent 36 supporting and cushioning devices 16 fit over the afore-37 mentioned end loops 21 and 22 on the grab handles 19 and 20 bL~*Z
1 and the securing and release mechanisms15 pass through 2 these loops 21 and 22 after passing through the holes 3 in the centers of the supporting and cushioning devices 16 4 and through the holes 14 in the planar members. Figure 4 illustrates the relationship between the component parts 6 herein mentioned and shows the flexible grab handles 19 7 and 20 as described. These grab handles 19 and 20 facili-8 tate grabbing, lifting, moving and carrying the invention
9 about. They also allow for decorative storage of the portable chartholder and table by allowing it to be hung 11 in picture fashion horizontally on any bulkhead, wall, 12 or other horizontal surface.
13 The distinguishing features of the portable chart-14 holder and table herein described include, but are not limited to the following features and characteristics:
16 I. RIGID, PLANAR MEMBERS
17 The rigid, planar members,at least one of which 18 is transparent (preferably both are transparent),allow 19 charts and other graphic material to be held flat and immovable. This allows a true distortion free 21 view of the material secured between the viewing surfaces.
22 When both viewing surfaces are transparent, maxi~um ex-23 ~osure of the charts or other materials is possible. More-24 over, since most charts are printed on both sides, the preferred emxXln.nt jallows the user to uiew both sides of a single 26 chart without having to remove the chart and turn it over.
27 All the user need do is turn the entire invention over 28 to expose to view the opposite side of the mater'ial secured 29 between the two transparent planar members. The nature of the viewing membersalso allow \ the plotting and charting 31 of courses and distances right on the viewing surfaces, 32 making unnecessary repeated marking and erasing of the 33 charts themselves. The planar members may be marked with 34 a standard"china marker"or grease pencil, which markings are removable from the viewing surfaces by means of normal 36 paper towel or tissue or any ordinary piece of cloth.
37 The planar members also provide protection for charts - ~ ` .
7 11~6~2 1 secured between them from damage or distortion which 2 might be caused by wind, water, or other elements.
3 II. CUSHIONING AND SUPPORTING DEVICES
4 A unique feature of the invention is that it has on its perimeter and extending out therefrom cushioning and support-6 ing devices 15 which protect against breakage of the invention's ~n 7 component parts, as well as protect other objects and sur-8 faces from being marred, scratched, cracked or broken by 9 the chartholder. Therefore, if the chartholder of the in-vention is tossed about in heavy weather in a boat or in 11 an aircraft, or is dropped by the user, the chartholder 12 itself is protected against damage, and the parts of the 13 boat or aircraft with which the invention comes into con-14 tact will not be marred or damaged by it. The cushioning and supporting devices also prevent the component parts 16 of the chartholder from marring any other horizontal planar 17 surface, such as a table top or a staionary chart table on 18 which the chartholder of the invention might be positioned 19 for use. The cushioning and supporting devices 15 also provide substantial slip resistence, so that the invention 21 will not easily slip from any stationary \char~ table, cock-22 pit seat, or any horizontal plane on which it is placed 23 for use.
24 III. SECURING AND RELEASE MECEIANISMS
The securing and release mechanisms 16 are manual-26 ly operable. This allows the user to quickly separate the 27 viewing surfaces to adjust or change any chart or other 28 material being used in con~unction with the invention.
29 The securing and release mechanismS 16 have adjustable tension which allows the user to tightly secure all com-31 ponent parts to each other by manually tightening the se-32 curing and release mechanisms 16. The qecurin~ and relcase 33 mechanisms 16 may also be operated with the use of common 34 hand tools such as pliers and/or screwdrivers if the user desires to do so.
.
liS~lt; *2 1 IV. FLEXIBLE GRAB HANDLES
2 The flexible grab handles 19 and 20 extending out 3 from and along the outer edges of the chartholder facilitate 4 grabbing, moving, carrying, and lifting of the invention.
The flexible grab handles also permit the chartholder to 6 be stored horizontally by hanging it, picture fashion, on 7 a bulkhead, wall or any other horizontal surface. This 8 also permits the chartholder to be used as a decorative item 9 by hanging it, as one might hang a pic~ure, on a wall at home, or elsewhere.
11 Since the chartholder of the invention is complete-12 ly portable, it may be used at any angle or used flat, 13 either as a lap table, or propped up against, or laid flat 14 upon any other surface in a cockpit or cabin of a boat, an aircraft, or any other type of vehicle.
16 This invention in its broader aspect is not limited 17 to the specific details shown and described and departures 18 may be made from such details without departing from the 19 principles of the invention and without sacrificing its chief advantages.

3 II. CUSHIONING AND SUPPORTING DEVICES
4 A unique feature of the invention is that it has on its perimeter and extending out therefrom cushioning and support-6 ing devices 15 which protect against breakage of the invention's ~n 7 component parts, as well as protect other objects and sur-8 faces from being marred, scratched, cracked or broken by 9 the chartholder. Therefore, if the chartholder of the in-vention is tossed about in heavy weather in a boat or in 11 an aircraft, or is dropped by the user, the chartholder 12 itself is protected against damage, and the parts of the 13 boat or aircraft with which the invention comes into con-14 tact will not be marred or damaged by it. The cushioning and supporting devices also prevent the component parts 16 of the chartholder from marring any other horizontal planar 17 surface, such as a table top or a staionary chart table on 18 which the chartholder of the invention might be positioned 19 for use. The cushioning and supporting devices 15 also provide substantial slip resistence, so that the invention 21 will not easily slip from any stationary \char~ table, cock-22 pit seat, or any horizontal plane on which it is placed 23 for use.
24 III. SECURING AND RELEASE MECEIANISMS
The securing and release mechanisms 16 are manual-26 ly operable. This allows the user to quickly separate the 27 viewing surfaces to adjust or change any chart or other 28 material being used in con~unction with the invention.
29 The securing and release mechanismS 16 have adjustable tension which allows the user to tightly secure all com-31 ponent parts to each other by manually tightening the se-32 curing and release mechanisms 16. The qecurin~ and relcase 33 mechanisms 16 may also be operated with the use of common 34 hand tools such as pliers and/or screwdrivers if the user desires to do so.
