The present disclosure relates generally to office and medical supplies. More specifically, embodiments of the present disclosure relate to a writing surface including a clipboard. The clipboard is foldable along at least one axis through a hinge to facilitate a reducing of writing area and overall size of the clipboard for transportation and/or storage.
Numerous occupations, hobbies, and other endeavors requires the use of a transportable and storable writing surface that is moveable between various locations and provides an area on which a user may write, draw, and/or otherwise make notations while at the various locations. One example of the writing surface is a clipboard. Clipboards have been used to facilitate note-taking. Clipboards have also been used to assist in the organization of papers while taking notes or reading, including providing a way to secure the papers on which the notes are being taken and/or that are being read, providing a way to secure the papers during transportation and/or storage of the clipboard, and the like. In general, the clipboard can be a highly versatile and useful tool. However, providing a suitable writing surface often requires a clipboard be large or otherwise cumbersome for a user, including during transportation and/or storage.
Accordingly, there is a long-felt but unmet need for a foldable clipboard. The clipboard should provide an unfolded or non-compact form with a large surface that facilitates note-taking or reading when in a first configuration. The clipboard should also provide a folded or compact form that allows for increased ease of transportation and/or storage when in a second configuration. The clipboard should also include components to facilitate the transition between the first configuration and the second configuration. The clipboard should also provide attachment features that retain items such as paper and the like against a surface of the clipboard when note-taking, transportation of the items, storage of the items, and the like.
Aspects of the present disclosure are directed to a foldable clipboard. The foldable clipboard includes at least two support panels that are coupled together. The foldable clipboard includes an attachment feature that retains items such as paper against a surface of the clipboard. The foldable clipboard is configured to transition between an unfolded configuration that is non-compact and provides a substantially flat surface for a user, and a folded configuration that is compact for transportation and/or storage.
In some aspects of the present disclosure, the at least two support panels are coupled together with at least one actuation component that facilitate the transition of the clipboard between the folded configuration and the unfolded configuration. When in the unfolded configuration, the clipboard may provide a surface that is large enough for a user to make notations, to support paper being read, and the like. The at least two support panels may be proximate to each other along a first set of adjacent surfaces, and may provide a substantially flat writing surface. When in the folded configuration, the clipboard may be in a compact form that facilitates an increased ease in transportation and/or stage. The at least two support panels may be proximate to each other along a second set of adjacent surfaces.
In some embodiments, the at least one actuation component (e.g., a hinge, or the like) may be configured to facilitate a substantially flush interface between adjacent surfaces when the at least three support panels are in the unfolded configuration and/or the folded configuration. Where there are at least three support panels and at least two actuation components, the at least two actuation components may be differently configured to facilitate the substantially flush interface between each respective set of adjacent surfaces.
In some aspects of the present disclosure, the clipboard includes an attachment feature that retains items such as paper against a surface of the clipboard. The attachment feature (e.g., such as a clip, or the like) may be positioned on or proximate to the writing surface available when the clipboard is in the unfolded configuration, to retain paper on the writing surface.
In some aspects of the present disclosure, the clipboard may include an attached or unattached sheet or cover that can span across the writing surface when the clipboard is in the unfolded configuration to provide a smooth surface over the seam between proximate support panels. In other embodiments, the sheet or cover may also be usable to assist in retaining the clipboard in the folded configuration, to prevent an unintended transition from the folder configuration to the unfolded configuration.
In some aspects of the present disclosure, the clipboard includes a locking mechanism or other engaging feature (e.g., a latch, or the like) that causes the clipboard to remain in the folded position or the unfolded position when engaged. The locking mechanism or other engaging feature may be in addition to or instead of the sheet or cover, as described through the present disclosure.
In other aspects of the present disclosure, one or more surfaces may be usable as a writing surface and/or may have items such as paper retained to the surface via an attachment feature when the clipboard is in the folded configuration.

U.S. Pat. No. 7,673,908 (the '908 Patent) depicts an example foldable clipboard, and is incorporated herein in its entirety. The present disclosure provides numerous improvements over the clipboard of the '908 Patent. For example, the clipboard 100 as embodied in the present disclosure is capable of a more compact and storable configuration, as the increased number of panels reduces the overall footprint of the clipboard 100 when in the folded configuration. In addition, the clipboard 100 of the present disclosure differs from the '908 Patent with respect to the arrangement and operation of the actuation components (e.g., such as hinges) between various support panels of the clipboard 100. Further, the clipboard 100 of the present disclosure differs from the clipboard of the '908 Patent in regards to the orientation of an attachment feature relative to the movement of the actuation components and subsequent folding/unfolding of the support panels by the actuation components—namely, the clipboard 100 of the present disclosure folds and unfolds in the same direction as the document being held by the attachment feature via multiple sets of offsetting hinges.
In certain embodiments, the clipboard 100 includes a top support panel 102 with a top upper surface 104, a middle support panel 106 with a middle upper surface 108, and a bottom support panel 110 with a bottom upper surface 112. Some or all of the upper surfaces 104, 108, and 112 form a combined upper surface 114 (or writing surface) on the front of the support panels 102, 106, and 110. It is noted, however, that any surface on the front (e.g., the combined upper surface 114 with surfaces 104, 108, 112) or rear (e.g., a combined lower surface 178 with surface 172, 174, 176, as described in detail herein) of the support panels 102, 106, and 110 may be usable as a writing surface, without departing from the scope of the present disclosure.
The top support panel 102 and/or the bottom support panel 110 may include rounded corners to prevent the clipboard 100 from catching on a pocket, purse, or other carrying and storage device when in the folded or unfolded positions. It is noted, here, that the top support panel 102 and/or the bottom support panel 110 may include squared corners or corners other not fabricated with additional manufacturing steps (e.g., to decrease manufacturing costs for the clipboard 100) without departing from the scope of the present disclosure.
In some embodiments, the top support panel 102, the middle support panel 106, and the bottom support panel 110 are substantially equal in at least one dimension. In one non-limiting example, the support panels 102, 106, 110 may be configured such that the respective upper surfaces 104, 108, 112 are each approximately one third of the combined upper surface 114, with a top edge 116 of the top support panel 102 and a bottom edge 118 of the bottom support panel 110 overlapping when the clipboard 110 is in a folded or compact position (e.g., as illustrated in
It is noted, however, that the support panels 102, 106, 110 and respective upper surfaces 104, 108, 112 may be configured in any number of ways without departing from the scope of the present disclosure. In another non-limiting example, the middle support panel 106 may be approximately twice as large in at least one dimension at the top support panel 102 and/or the bottom support panel 110, such that the support panels 102, 110 fold onto the middle support panel 106 with the top edge 116 of the top support panel 102 and the bottom edge 118 of the bottom support panel 110 meeting over the middle upper surface 108 of the middle support panel 106 when the clipboard 110 is in a folded or compact position.
In some embodiments, the support panels 102, 106, 110 are fabricated from a metal such as aluminum, stainless steel (e.g., surgical stainless steel), or the like; a plastic; pressed board; or another suitable material. It is noted that aluminum provides a very strong, light-weight panel that is very durable. In addition, plastic also provides a fairly strong and light-weight panel that is relatively inexpensive to manufacture.
In various embodiments, the top support panel 102 and the middle support panel 106 are moveably connected via at least one actuation component 120. The at least one actuation component 120 may include a hinge 120 with a set of hinge plates 122 that are pivotably coupled via a hinge pin 124 and rotatable about an axis 126 through the hinge pin 124. For example, the clipboard 110 may include a set of hinges 120 positioned on the top support panel 102 and the middle support panel 106 on opposite sides (e.g., left and right sides) of the clipboard 100. By way of another example, the hinge 120 is a piano hinge (or other similar continuous hinge) with hinge plates 122 positioned at a bottom edge 128 of the top support panel 102 and an adjacent top edge 130 of the middle support panel 106. Additional hinge examples include, but are not limited to, a butt hinge or a knife hinge (or other similar pivot hinge). The hinge pin 124 may include a gasket, bearing assembly, and/or other suitable mechanism for facilitating the pivotable interconnection between the hinge plates 122.
It is noted that the axes 126 of the hinge pins 124 through the hinge plates 122 of the hinges 120 may be substantially coaxial, where there are multiple hinges 120.
In some embodiments, the hinge plates 122 are integrated with and formed as a part of a respective top support panel 102 and/or middle support panel 106. For example, the hinge plate 122 may be fabricated with a respective top support panel 102 and/or middle support panel 106 via one or more manufacturing processes including stamping, cutting, bending, or the like. In other embodiments, the hinge plates 122 are separate components from (and coupled to) a respective top support panel 102 and/or middle support panel 106.
In certain embodiments, the middle support panel 106 and the bottom support panel 110 are moveably connected via at least one actuation component 132. The at least one actuation component 132 may include a hinge 132 with a set of hinge plates 134 that are pivotably coupled via a hinge pin 136 and rotatable about an axis 138 through the hinge pin 136. For example, the clipboard 110 may include a set of hinges 132 positioned on the middle support panel 106 and the bottom support panel 110 on opposite sides (e.g., left and right sides) of the clipboard 100. By way of another example, the hinge 132 is a piano hinge with hinge plates 134 positioned at a bottom edge 140 of the middle support panel 106 and an adjacent top edge 142 of the bottom support panel 110. The hinge pin 136 may include a gasket, bearing assembly, and/or other suitable mechanism for facilitating the pivotable interconnection between the hinge plates 134.
It is noted that the axes 138 of the hinge pins 136 through the hinge plates 134 of the hinges 132 may be substantially coaxial, where there are multiple hinges 132.
In some embodiments, the hinge plates 134 are integrated with and formed as a part of a respective middle support panel 106 and/or bottom support panel 110. For example, the hinge plate 134 may be fabricated with a respective middle support panel 106 and/or bottom support panel 110 via one or more manufacturing processes including stamping, cutting, bending, or the like. In other embodiments, the hinge plates 134 are separate components from (and coupled to) a respective middle support panel 106 and/or bottom support panel 110.
In various embodiments, the hinges 120, 132 are operable to cause the respective top support panel 102 and the bottom support panel 110 to transition between an unfolded or open position to a folded or compact position relative to the middle support panel 106. In general, the hinges 120, 132 may be selected for and/or positioned on the clipboard 100 so as to prevent a raised portion or obstruction on the writing surface. In addition, the hinges 120, 132 may be selected for weight reduction, and/or for comfort when a user is holding the clipboard 100 (e.g., based on anthropometric data for the 50th percentile, the 95th percentile, or the like).
In one non-limiting example, the hinges 120, 132 may be configured such that both the top support panel 102 and the bottom support panel 110 are folded over on top of (or folded underneath) the middle support panel 106 when the clipboard 100 is in the folded or compact position. In this example, the support panels 102, 106, 110 may be in a U-configuration (e.g., as illustrated in
In another non-limiting example, the hinges 120, 132 may be configured such that the top support panel 102 or the bottom support panel 110 are folded over and beneath the middle support panel 106 when the clipboard 100 is in the folded or compact position. In this example, the support panels 102, 106, 110 may be in a Z-configuration during transition between the unfolded or open position and the folded or compact position.
In certain embodiments, the hinges 120, 132 are operable to allow the top support panel 102 and/or the bottom support panel 110 to pivot approximately 180° relative to the middle support panel 106 between the unfolded and folded positions. For example, when in the unfolded position, the top support panel 102 and the bottom support panel 110 are each pivoted approximately 180′ relative to the middle support panel 106. By way of another example, when in the folded position the top support panel 102 and the bottom support panel 110 are each generally 0°±20° relative the middle support panel 106.
It is noted the clipboard 100 has a substantially constant thickness 144 that is consistent between each of the support panels 102, 106, 110. The thickness 144, in combination with the proximity of the respective edges 128, 130 of the support panels 102, 106 and the respective edges 140, 142 of the support panels 106, 110 provide the clipboard 100 with a select amount of rigidity when in the unfolded or open position. The engaging of the edges 128, 130 and edges 140, 142 having the thickness 144 prevents the support panels 102, 106, 110 from opening past the respective intended positions when the clipboard 100 is in the unfolded or open position. The constant and consistent thickness 144 of the clipboard 100 facilitates the support panels 102, 106, 110 being substantially rigid and also facilitates the combined upper surface 114 being substantially planar, so as to provide a good support for writing.
It is noted, however, the hinges 120, 132 may be configured to allow the support panels 102, 106, 110 to fold past 180 degrees from the folded position, including up to 360 degrees from the folded position such that the opposite surfaces of the support panels 102, 106, 110 are in contact, without departing from the scope of the present disclosure. For example, the support panels 102, 106, 110 may include a gap that is large enough to prevent the edges 128, 130 and the edges 140, 142 from interacting when the top support panel 102 and/or the bottom support panel 110 are pivoting with respect to the middle panel 106.
It is noted the support panels 102, 106, 110 may be semi-rigid, depending on the type and thickness of the material forming the support panels 102, 106, 110, for purposes of the present disclosure. In addition, it is noted the support panels 102, 106, 110 may be substantially rigid, depending on the type and thickness of the material forming the support panels 102, 106, 110, for purposes of the present disclosure.
In certain embodiments, as illustrated in at least
The clipboard 100 also includes hinges 132a, 132b coupling the bottom support panel 110 to the middle support panel 106. Each of the hinges 132a, 132b include a set of hinge plates 134a, 134b coupled via a pin 136 (e.g., the pin 136 illustrated in at least
The adjacent and substantially parallel movement by the hinge plates 122a, 122b and the hinge plates 134a, 134b on each support panel 102, 106, 110 is facilitated by the hinge plates 122a, 122b and the hinge plates 134a, 134b being different distances from a plane 146 positioned midway between side edges 148 and 150 and passing through the top edge 116 and the bottom edge 118 of the clipboard 100, while the side edges 148 and 150 are substantially equal in distance from the plane 146. Where each set of adjacent panels 102, 106 and 106, 110 have multiple hinges 120a, 120b and multiple hinges 132a, 132b, the hinge plates 122a, 122b and the hinge plates 134a, 134b are dimensioned to allow for offsetting overlaps between the respective sets of hinges 120a, 120b and hinges 132a, 132b.
The side edge 148 includes a side portion 152 of the top panel support 102, a side portion 154 of the middle panel support 106, and a side portion 156 of the bottom panel support 110. The offsetting of the hinge plates 122a, 122b and the hinge plates 134a, 134b allows the edge of the side portions 152, 154, 156 to be substantially adjacent and aligned in a first direction (e.g., a y-direction along the length of the clipboard 100) when the clipboard 100 is in the unfolded configuration to form the side edge 148, and to be substantially adjacent and aligned in a second direction (e.g., a z-direction) when the clipboard 100 is in the folded configuration.
The side edge 150 includes a side portion 158 of the top panel support 102, a side portion 160 of the middle panel support 106, and a side portion 162 of the bottom panel support 110. The offsetting of the hinge plates 122a, 122b and the hinge plates 134a, 134b allows the edge of the side portions 158, 160, 162 to be substantially adjacent and aligned in the first direction (e.g., the y-direction along the length of the clipboard 100) when the clipboard 100 is in the unfolded configuration to form the side edge 150, and to be substantially adjacent and aligned in the second direction (e.g., the z-direction) when the clipboard 100 is in the folded configuration.
The offsetting of the hinge plates 122a, 122b and the hinge plates 134a, 134b at the different distances from the plane 146 allows for a more compact hinge arrangement and a total reduced width of the clipboard 100. In addition, the offsetting of the hinge plates 122a, 122b and the hinge plates 134a, 134b at the different distances from the plane 146 allows for the top support panel 102 and the bottom support panel 110 to be the same fabricated component, aside from any final fabrication steps (e.g., drilling, or the like) necessary to couple an attachment feature 164 to the top support panel 102, thus reducing manufacturing costs.
Where there are multiple hinges 120 (e.g, hinges 120a, 120b as illustrated in
Where there are multiple hinges 132 (e.g., hinges 132a, 132b as illustrated in
In certain embodiments, the clipboard 100 includes one or more attachment features 164. The attachment feature 164 may include a spring clip sized to hold up to 50 or more pieces of paper to the clipboard 100. It is noted, however, the clipboard 100 may utilize other types of attachment features including, but not limited to, a low profile wire clip, a magnetic clip, two- or three-ring binder clips, screw-down clip, and the like without departing from the scope of the present disclosure.
The attachment feature 164 may be positioned on the top upper surface 104 and proximate to the top edge 116 of the top support panel 102. The top upper surface 104 may include one or more apertures 166 configured to receive the attachment feature 164. For example, the attachment feature 164 may be coupled to the top support panel 102 via the one or more apertures 166 (e.g., with fasteners, or the like), such that the attachment feature 164 may be removable from and re-attachable to the top support panel 102 as desired. By way of another example, the attachment feature 164 may be affixed to the top support panel 102 (e.g., with rivets, an adhesive, or the like) and thus immovable.
It is noted the attachment features 164 may be operable as a spacer between the support panels 102, 106, 110 to prevent contact between the support panels 102, 106, 110. For example, taller attachment features 164 may prevent the clipboard from fully folding to 0°, while shorter attachment features 164 may allow the clipboard to fold to 0° or past 0°.
In certain embodiments, the clipboard 100 may include one or more additional sets of apertures 166. The additional sets of apertures 166 may be positioned proximate to the side portion 152 and/or the side portion 158 of the top panel support 102. The additional sets of apertures 166 may be positioned proximate to the side portion 154 and/or the side portion 160 of the middle panel support 106. The additional sets of apertures 166 may be positioned proximate to the side portion 156 and/or the side portion 162 of the bottom panel support 110. The additional sets of apertures 166 may be positioned proximate to the bottom edge 118 of the clipboard 100.
Where the attachment feature 164 is removable (e.g., couplable to the apertures 166 via fasteners, or the like), the attachment feature 164 may be repositionable between any of the sets of apertures 166. In addition, the apertures 166 may pass through the support panels 102, 106, 110. In this regard, the attachment feature 164 may be usable on any of the support panels 102, 106, 110 when the clipboard 100 is in either the unfolded or open configuration and/or the folded or compact configuration.
When the interior edges 128, 130 of the adjacent panels 102, 106 and/or the interior edges 140, 142 of the adjacent panels 106, 110 are aligned substantially adjacent to one another, the support panels 102, 106, 110 collectively form a substantially continuous surface (e.g., the combined upper surface 114). In this configuration, the unfolded clipboard 100 may operate similarly as a rigid, single-panel clipboard known in the art. However, small misalignments or gaps may affect the ability of the foldable clipboard 100 to serve as a continuous and uninterrupted writing surface.
In certain embodiments, the clipboard 100 includes a sheet or other layer 168 that is positionable over at least a portion of the combined upper surface 114. The sheet or other layer 168 may be a substantially continuous piece of material, and may cover the gaps and/or misalignment between adjacent edges 128, 130 and/or 140, 142 between the respective panels 102, 106 and/or 106, 110.
The sheet or other layer 168 may be flexible, to allow for the sheet to transition with the support panels 102, 106, 110 between the unfolded or open position and the folded or compact position of the clipboard 100. The sheet or other layer 168 can be made from a variety of different materials, including, but not limited to, 0.010″ vinyl. It is noted that thicker or thinner flexible material may be used, such as polycarbonate or polyester, without departing from the scope of the present disclosure.
In some embodiments, the sheet or other layer 168 may be securable the secured to the combined upper surface 114 in a temporary manner, with a removable adhesive, fasteners, integrated attachment features in the upper surfaces 104, 108, 112, or other similar temporary attachment features. Alternatively, in other embodiments, the sheet or other layer 168 may be secured to the combined upper surface 114 in a permanent manner, with a non-removable adhesive, fasteners, integrated attachment features in the upper surfaces 104, 108, 112, or other similar permanent attachment features. Further, in other embodiments the sheet or other layer 168 may not be secured to the combined upper surface 114.
Where the sheet or other layer 168 is secured, it is noted that the position or place of securing may be a predetermined distance from the adjacent edges 128, 130 and/or 140, 142 so as to not interfere with the pivoting of the respective support panels 102, 106 and/or 106, 110 relative to one another. In addition, it is noted that the securing may be a predetermined distance from one or more of the adjacent edge sides 148, 150 of the clipboard 100 (e.g., and thus one or more of the side portions 152, 154, 156, 158, 160, 162 of the panels 102, 106, 110) so as to not interfere with the pivoting of the respective support panels 102, 106 and/or 106, 110 relative to one another.
In one non-limiting example, the sheet or other layer 168 may not be adhered to the support panels 102, 106, 110 within one inch of the interior edges 128, 130, 140, 142 and/or the edges of the side portions 154, 156, 158, 160, 162, 164. However, it is contemplated that more or less of the sheet or other layer 168 can be left unadhered depending on the gap requirements between support panels for the selected hinges 120, 132. When a portion of the sheet or other layer 168 is left unadhered, the sheet is allowed to form a curved (or non-creasing) surface when the clipboard 100 is folded. This can help prevent papers held by the clipboard from creasing when the clipboard 100 is folded.
In some embodiments, the upper surfaces 104, 108, 112 and/or the sheet or other layer 168 is configurable to provide information to a user, with marking sections 170. The marking sections 170 may be pre-printed, may be non-permanently marked on by the user, and/or may be permanently marked on by the user. In one non-limiting example, on a clipboard 100 that is usable by doctors or medical students, the upper surfaces 104, 108, 112 and/or the sheet or other layer 168 may include reference information in the marking sections 170 used by doctors and medical students when charting patients. In another non-limiting example, on a clipboard 100 that is usable by a building inspector, the upper surfaces 104, 108, 112 and/or the sheet or other layer 168 can include building code and regulation information in the marking sections 170. In another non-limiting example, on a clipboard 100 that is usable by a coach, the upper surfaces 104, 108, 112 and/or the sheet or other layer 168 can include personnel information and an index of plays in the marking sections 170. In general, the upper surfaces 104, 108, 112 and/or the sheet or other layer 168 allows the clipboard 100 to be customized for virtually any task in the marking sections 170. It is noted the clipboard 100 may be further customized by applying information to the backsides of the support panels 102, 106, 110.
In certain embodiments, as illustrated in at least
Although certain embodiments of the present disclosure are directed to a single flexible sheet or other layer 168 positioned on or proximate to the combined upper surface 114, it is noted that the clipboard 100 may include any number of sheets or layers 168, with any number of marking sections 170, without departing from the scope of the present disclosure. For example, the clipboard 100 may include one or more sheets or layers 168 with one or more marking sections 170 positioned on or proximate to the combined upper surface 114; one or more of the upper surfaces 104, 108, 112 either separately or in combination; the combined lower surface 178; and/or one or more of the lower surfaces 172, 174, 176 either separately or in combination. In addition, in certain embodiments the clipboard 100 may not include any sheets or layers 168 positioned on or proximate to the combined upper surface 114, without departing from the scope of the present disclosure.
As illustrated in
Referring generally to
In some embodiments, the hinges 120, 132 and/or the adjacent panels 102, 106 and/or the adjacent panels 106, 110 may have locking components or mechanisms that engage when the clipboard 100 is fully in the unfolded or open position, and/or the folded or compact position. For example, the locking components or mechanisms hold the clipboard 100 in the unfolded or open position to prevent collapsing when attempting to write on the combined upper surface 114. By way of another example, the locking components or mechanisms hold the clipboard 100 in the folded or compact position to prevent the clipboard 100 from opening when stored or being transported.
In one non-limiting example, the top support panel 102 and the bottom support panel 110 may be 8.000 inches wide with two additional 0.375 inches radius corner, for a total surface width of 8.750 inches. The top support panel 102 and the bottom support panel 110 may be 3.850 inches in length. The middle support panel 106 may similarly have a surface width of 8.750 inches and may be 3.797 inches in length, such that the combined length of the support panels 102, 106, 110 when the clipboard 100 is in the unfolded or open position is 11.497 inches.
In one non-limiting example, the hinge plates 122, 134 may be 1.066 inches in length and 0.485 inches in height. The hinge plates 122, 134 may include a first larger corner radius of 0.300 inches and a second smaller corner radius of 0.201 inches. The second smaller corner radius includes a pin bore that is 0.156 inches in diameter. A central point of the pin bore is 0.202 inches from the outermost radius point of the second smaller corner, 0.565 inches from the first large corner central point, or 0.865 inches from the opposite end of the hinge plates 122, 134. The outermost radius point on the pin bore is 0.124 inches from the outermost radius point of the second smaller corner.
The second smaller corner radius of the hinge plates 122, 134 may extend beyond the length of the panels 102, 106, 110 as defined between respective top and bottom edges of the panels 102, 106, 110 described throughout the present disclosure. For example, a diameter line through the central point of the pin bore may be aligned with the bottom edge 128 of the top support panel 102, the top edge 130 of the middle support panel 106, the bottom edge 140 of the middle support panel 106, and/or the top edge 142 of the bottom support panel 110, such that the length of the hinge plates 122, 134 that aligns with the surfaces 104, 108, 112 of the support panels 102, 106, 110 is 0.865 inches. The distance between the internal edges of the hinge plates 122, 134 is 2.068 inches on the middle support panel 106.
As illustrated in
It is noted the extending beyond the lengths of the panels 102, 106, 110 by the hinge plates 122, 134 and/or the heights of the hinge plates 122, 134 may provide an additional distance from the respective upper surfaces 104, 108, 112 that may accommodate the dimensions of the attachment feature 164 (e.g., is at least the total height of the attachment feature 164).
For example, the top support panel 102 may be capable between an unfolded or open position that is substantially at 0° relative to the middle support panel 106 and a folded or compact position that is substantially at 1800 relative to the middle support panel 106. Here, the top lower surface 172 of the top support panel 102 and the middle lower surface 174 of the middle support panel 106 are substantially parallel when the top support panel 102 is in either the unfolded or open position (e.g., in a shared or parallel plane), or the folded or compact position (e.g., in different, substantially parallel planes). It is noted, however, that if the distance is greater than the total height of the attachment feature 164, the top support panel 102 may be beyond parallel and slant at an angle with respect to the middle support panel 106 (e.g., having rotated more than 180° with respect to the middle support panel 106) when in the folded or compact position.
By way of another example, the bottom support panel 102 may be capable between an unfolded or open position that is substantially at 0° relative to the middle support panel 106 and a folded or compact position that is substantially at 1800 relative to the middle support panel 106. Here, the bottom lower surface 176 of the bottom support panel 110 and the middle lower surface 174 of the middle support panel 106 are substantially parallel when the bottom support panel 110 is in either the unfolded or open position (e.g., in a shared or parallel plane), or the folded or compact position (e.g., in different, substantially parallel planes). It is noted, however, that the bottom support panel 110 may slant at an angle with respect to the middle support panel 106 (e.g., having rotated less than 180° with respect to the middle support panel 106) when in the folded or compact position.
It is noted the above relationships may similarly hold true for the top lower surface 172 of the top support panel 102 and the bottom lower surface 176 of the bottom support panel being substantially parallel in shared or different planes, without departing from the scope of the present disclosure.
This non-limiting example of dimensions results in a clipboard 100 that can fully support a letter-sized piece of paper (e.g., 8.5×11 inches) when the clipboard 100 is in unfolded or open configuration. The dimensions also allow the clipboard 100 to be stowed in a pocket (e.g., of a doctor's white coat) in a sub-4 inch×sub-8.5×sub-1.5 inch footprint when it is in the folded or compact configuration. It is noted that the clipboard 100 can be sized and shaped differently to accommodate differently sized paper, different storage requirements, and/or any number of other factors without departing from the scope of this disclosure.
It is noted that the distancing of the hinge plates 122a, 122b and/or hinge plates 134a, 134b may be opposite, reversed, and/or generally different from the above non-limiting example, without departing from the scope of the present disclosure. For example, where the apertures 166 are symmetrically positioned about the plane 146, the attachment features 164 may be coupled to the clipboard 100 such that the combined upper surface 114 or the combined lower surface 178 is usable as a writing surface. Coupling the attachment feature 164 to the top upper surface 104 such that the combined upper surface 114 is the writing surface results in the hinges 120a, 120b and hinges 132a, 132b being offset in a first arrangement. Alternatively, coupling the attachment feature 164 to the top lower surface 172 such that the combined lower surface 178 is the writing surface results in the hinges 120a, 120b and hinges 132a, 132b being offset in a second arrangement that is flipped from the first arrangement. In the second arrangement, the respective distances that hinge plates are exterior to respective side portions is reversed that of the first arrangement.
In some embodiments, the hinge pins 124, 136 are removable from the hinges 120, 132. As illustrated with the above exemplary set of dimensions, the hinge plates 122, 134 may be similarly-dimensioned outward from respective side portions of the various support panels 102, 106, 110. As such, the top support panel 102 and the bottom support panel 110 may be swappable or interchangeable, being substantially identical in size and shape. In addition, the length of the clipboard 100 may be increased with the insertion of additional middle support plates 106 between the top support plate 102 and the middle support plate 106, between the middle support plate 106 and the bottom support plate 110, and/or between a first middle support plate 106 and a second middle support plate 106. In this regard, the clipboard 100 presents the possibility of a highly modular improvement over known art, one that is configurable to a particular user's needs. It is noted the height of the hinge plates 122, 134 and/or the gap between adjacent support panels may need to be adjusted to enable the continued collapsing from the unfolded or open position into the folded or compact position, which may be accomplished without departing from the scope of the present disclosure.
In this regard, the clipboard 100 according to the present disclosure provide a smooth writing surface when in the unfolded configuration, while at the same time providing improved portability and storability when in the folded configuration. Furthermore, when in the folded configuration, the clipboard 100 may house papers it is holding with the attachment feature 164 in an internal cavity defined by the support panels 102, 106, 110, thus providing an increased level of security for the papers both in terms of being held in place and the confidentiality regarding the content of the documents as necessary.
