Public surfaces such as baby changing tables, or coffee shop tables, often have limited space or can lack a flat surface to place items on. Because these surfaces are so rarely used, and typically owned by someone else, modifying the surface in a permanent way is too time consuming and cost prohibitive. Furthermore, the cleanliness of the public surfaces is never certain.
In other situations, a surface area might not be big enough for one more item, but the need to place another item on the surface might not be great enough to necessitate permanently modifying the surface. Additionally, the surrounding space might not allow for a larger permanent surface.
The need remains for a device that has certain improved features allowing for temporarily providing an extra surface area on a flat surface such as a baby changing table or a table in a public space.
The disclosed subject matter allows for temporarily creating extra flat surface space that extends from a relatively flat surface or wall. The present disclosure additionally has the advantage of being collapsible into a smaller size to allow ease of portability.
The novel features believed characteristic of the disclosed subject matter will be set forth in any claims that are filed later. The disclosed subject matter itself, however, as well as a preferred mode of use, further objectives, and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:
Reference now should be made to the drawings, in which the same reference numbers are used throughout the different figures to designate the same components.
The platform 12, comprises a plurality of interconnected support segments 24, and a first support segment 26. The interconnected support segments 24, along with the first support segment 26 may be interconnected through interlocking design aspects and or hinges, to allow the platform 12 to collapse in one direction and resist collapsing in the opposite direction. The support segments 24 are preferably a rigid material such as plastic, wood, or metal.
The counter-balance 14 is attached to the first support segment 28 to provide a non-permanent attachment to the table 18 and provide support to prevent the platform 12 from collapsing under the weight of items placed on top of it. The counter-balance 14 is preferably a rigid and dense material. Embodiments of the counter-balance may be comprised of any dense material, or any material that provides resistance to prevent the collapse of the platform. Alternatively, some embodiments of the counter-balance 14 may comprise suction cups, or magnetic material.
The strut 16, comprising a first strut segment 30, a plurality of interconnected strut segments 32, and an end strut segment 34. The first strut segment 30 is attached to the first support segment 28 and provides a for an upturned end strut segment 32 allowing a purse or other item to be hung on the strut 16 and add additional counter-balance to prevent the platform 12 from collapsing. The strut 16, is preferably a rigid material, having hinges and or an interconnected design component to connect the interconnected strut segments 32. However, other alternatives are contemplated. For example, strut 16 can have a rubber surface, a non-slip surface, or a magnetic material on portions of a strut segment. In some embodiments, the first strut 16 segment may comprise a spring loaded prong having a first-end and a second-end. The first end attaches to the first strut segment 30 in a manner allowing the prong to pivot from a parallel position with the first strut segment to a position perpendicular with the first strut segment. The prong is spring loaded, allowing the prong to store kinetic energy when pivoted away from the first strut segment. The stored kinetic energy then provides a force maintaining stability of the platform while the second end of the prong is in contact with a table surface.
Optionally, the storage configuration 40 may further be enabled by a magnetic component or material on the strut, which could allow the collapsible shelf to maintain the storage configuration without being encapsulated inside a container such as a bag as depicted in
In one embodiment the strut may comprise a curve or change in direction of the strut from a downward angle to an upward angle. This would enable the use of the strut 16 as a hook to hang items on. Items may include a purse, a diaper changing bag, or an electronics bag.
The following examples illustrate an embodiment of the present inventive subject matter but are not intended to limit the scope of the inventive subject matter.
In one example of the inventive subject matter the portable collapsible shelf 10 is collapsed into the storage configuration 40. The strut 16 may be collapsed such that a strut segment 28 may have a first magnetic component that magnetically connects to a second magnetic component of the platform 12. In this example, the first magnetic component of the strut segment 28 and the second magnetic component of the platform 12 may be comprised of metal, a magnet, a magnetic material, a rare-earth metal, a rare-earth magnet, or a material that has been magnetized. Additionally, the first and second magnetic component may be comprised of any material that allows for the first and second magnetic components to create a magnetic field to resist being pulled apart until enough force is applied to separate the first and second magnetic component.
In another example of the inventive subject matter the portable collapsible shelf 10 is expanded into the use configuration and placed in physical contact with sufficiently flat surface such as a diaper changing table, or a public table in a public space. The strut is expanded and engaged with a second surface that may be a wall, table leg, table support beam, or another surface that is perpendicular to the sufficiently flat surface. In this example, the point of contact on the strut, where the strut meets the second surface, may be a non-slip surface to increase stability and reduce the likelihood of the strut slipping and causing the platform to collapse because of a lack of support from the strut. The point of contact with the non-slip surface might be one end of the strut, along the length of the strut, or may be any point on the strut.
In another example of the inventive subject matter the portable collapsible shelf may have a platform that when extended into the use configuration may have one or more hinges along the side of the interconnected support segments that is perpendicular to a table or flat surface the apparatus is in contact with. The hinges may allow a plurality of interconnected support segments to change positions from being stacked vertically above the platform and a plurality of interconnected support segments to a position in parallel with and within the same plane as the platform and a plurality of interconnected support segments. In this example, the hinged plurality of interconnected support segments may allow for an increase of surface area of the platform and a more compact apparatus while in the storage configuration.
In some embodiments, the inventive subject matter may comprise a three-pronged pincer type grasp. The grasp would attach to the first support segment. The prongs may be spring loaded. In one embodiment, a first and second prong of the three-pronged pincer type grasp would contact the top surface of a table, and a third prong would contact the bottom surface of the table. This position would provide more stability to the platform by gripping the table with more force, thus preventing movement of the platform.
In an alternative embodiment, a single-prong is attached to the first support segment, and would contact the table or other surface on the bottom surface or opposite surface that the counter-balance contacts. The single-prong may be spring loaded. The single-prong may also be collapsible.
In one embodiment, a method for placing items on a collapsible shelf comprises unrolling a collapsible shelf into a use configuration, placing a counter-balance on a surface; extending a strut beneath the platform; and placing an object on the platform. The method may further comprise placing a purse or bag on the strut. Then, removing the object from the platform; collapsing the strut; removing the counter-balance from the surface; and collapsing the platform. After collapsing the collapsible shelf into a storage configuration, the collapsible shelf may be placed into a bag for transport or storage.
The present invention may be embodied in other forms without departing from the spirit and the essential attributes thereof, and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification, as indicating the scope of the invention.
This U.S. Non-Provisional Patent Application claims priority to the U.S. Provisional Patent Application No. 62/438,393 filed on Dec. 22, 2016 which is hereby incorporated by reference in its entirety. The present disclosure relates to a portable and collapsible shelf.
