SUMMARY OF THE INVENTION
The shopping list organizer of the present invention includes a clip board with a smooth writing surface on one side, and a contoured surface on the second side. Attached to the contoured side of the clip board is mounting means which permit the clipboard to be releasably mounted to a range of shopping cart handles of different size and shape. The mounting means also provides for the clipboard to releasably mount to a flat surface such as a refrigerator or wall. The mounting means allows the user to position the clipboard to a convenient angle and position on the shopping cart handle for optimum viewing and writing.
In one embodiment the mounting means consists of flip out loops made of a resilient or spring-like material such as metal or plastic that engage and hold onto the shopping cart handle.
In summary the shopping list writing tablet and mounting system according to the present invention includes a rigid substantially planar member sized to support a shopping list when the shopping list is mounted thereon. A means is provided for releasably mounting the shopping list on a first surface of the planar member, that is, the surface to be exposed to the user. A second means, mounted on a second side of the planar member, opposite the first side, is provided for releasably mounting the planar member on a flat substrate such as a wall, appliance door, or other residential surface commonly found in a household residence. At least one clip is hingedly mounted by a hinge means to the second side of the planar member for rotation about the hinge between a closed position substantially flush against the second side of the planar member and an open position substantially orthogonal to the second side of the planar member. In the open position, the clip is disposed for releasably mounting onto an elongate handle. In the closed position the clip is retracted so as to not interfere with operation of the means for releasably mounting the planar member on a flat substrate.
Each clip has at least one arm defining an aperture and an opening. The opening cooperates with the aperture for passing of the handle through the opening into the aperture. The aperture is sized to snugly retain the handle journalled in the aperture. A friction member is mounted in cooperation with the aperture when the clip is in the open position so as to bear the friction member against and frictionally engage the handle when the handle is releasably mounted in the aperture.
The means for releasably mounting the shopping list may be a resilient clip mounted to the first side of the planar member. The means for releasably mounting the planar member on a flat substrate may include at least one magnet, for example, a pair of magnets mounted spaced apart on opposite ends of the second side of the planar member, in which case the clip or clips may be hingedly mounted between the pair of magnets. The clips may be a pair of clips mounted so that, in their open position, the apertures on the pair of clips are aligned to accept the handle simultaneously mounted in both apertures. In one embodiment the planar member is elongate between the opposite ends, and the handle, when mounted in the pair of apertures, extends laterally across the planar member.
The clip or clips may be resilient or may otherwise be releasably mountable onto the handle so as to urge the handle against the friction member. For example, each clip may have a pair of opposed facing resilient hook-arms defining the aperture therebetween. The aperture may in one embodiment be substantially circular. The friction member may be mounted to the second side of the planar member so as to dispose at least a frictional bearing surface of the friction member into alignment with the aperture, that is, so as to engage a surface of the handle when the handle is mounted in the aperture.
In one embodiment the aperture has a vertex adjacent the second side of the planar member when the corresponding clip is in the open position. The frictional bearing surface may be adjacent the vertex or otherwise adjacent the rim of the clip around the aperture so as to dispose the bearing surface inwardly into the aperture. Thus, the handle when mounted in the aperture contacts and bears against the frictional bearing surface and not against the corresponding portion of the rim. The friction member may be advantageously resilient in order to increase the surface area in contact with handle, or may otherwise be adapted to frictionally grip the handle by other traction means including, teeth and the like.
In one embodiment the friction member extends between a pair of clips. The friction member may be mounted to the second side of the planar member so as to extend into the clip apertures when the pair of clips are in the closed position.
The second side of the planar member may have recesses therein, formed so that the clip or clips when in the closed position lie in the recesses. In the closed position each clip may be substantially contained within the recesses in the second side of the planar member.
The hinge means may provide for folding of a pair of clips inwardly from adjacent edges of the second side of the planar member.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
As seen in FIGS. 1 and 2, one embodiment of the present invention includes a writing board 1 (clipboard), the mounting assembly 2, resilient tactile sheet 6 on the surface that engages shopping cart handles, flat tactile or magnetic sheet 5 on the surface that engages flat surfaces such as the outer walls of refrigerators, a means to releasably “clip” 3 a paper note or notepad to the writing board, and a mount for a writing implement such as a pen or pencil 4.
Clipboard 1 has a smooth writing surface on its upper side, and a contoured surface on the opposite bottom side. The contoured surface includes a recess 7 for the mounting assembly 2 to fold into as shown in FIGS. 2a and 3a. 
As shown in FIG. 4, one embodiment of the mounting assembly includes a pair of conformal resilient loops 2, which engage by resiliently deforming so as to pass the shopping cart handle 8 through the openings 2a into the conformal body 2b of the loops, forcing the handle 8 in direction A against the resilient tactile sheet 6. The frictional force between the conformal loops 2 and the handle 8 once snugly mounted within the body 2b of each loop, and the friction force between the resilient tactile sheet 6 and the handle 8 at their interface 6a wherealong sheet 6 slightly deforms to follow the curvature of handle 8, as best seen in FIG. 3b, impedes unintentional rotation of the clipboard 1 about the handle 8. Consequently, in the preferred embodiment, when loops 2 are deployed in their open position orthogonal to the clipboard as in FIGS. 2 and 3, the vertices 2c of each loop lie behind a plane B containing the non-deformed contact surfaces 6b of sheet 6, that is, so that at least the contact surfaces extend into the aperture defined by the loop bodies 2b. 
FIGS. 5 & 6 shows one embodiment of the present invention mounted onto the door of a refrigerator.
The present invention can be releasably fastened to a wall or refrigerator, and can be removed and transported to the store where it can be releasably fastened to the handle 8 of a shopping cart or basket. This device consists of a clip board with the bottom surface profiled to allow flip out mounts to be recessed when stowed. The two flip-out mounts are mounted to the underside of the clipboard near each side edge of the clipboard. The spring loaded force of the loop shaped mounts, combined with the frictional force between the resilient tactile material of sheet 6 and the shopping cart handle 8 limits the rotation of the clip board about the shopping cart handle. The shopping list organizer can be attached to a shopping cart handle by sliding the mounts orthogonally over the handle until the handle is snugly secured. To release the shopping list holder the clipboard is simply pulled away from the handle until the device is removed.
The resilient tactile material of sheet 6 may be made of a silicon polymer such as the OctapadTM commercially available from Hiscoco Innovations Inc. of Kelowna, British Columbia, Canada.
The mounting means may be used in other applications where it is desirious to releasably mount a board, box, or device to an elongated member such as but not limited to the handle of a shopping cart.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
