Description

TECHNICAL FIELD

This invention relates generally to a portable utility shelf, and more specifically to a portable utility shelf that provides a quick connect/disconnect means, to attach the shelf to an object, and provide a user with a hands free shelf to operate a laptop computer. The features and improvements of the present invention, as described herein, are achieved while providing a portable workspace for a user.

DESCRIPTION OF RELATED ART

Laptop carriers are known in the art. Known laptop carriers require attachment to a user, such as a strap around the user's neck, or require a stand, such as a tabletop. For example, US2010/0038393A1 describes a laptop carrier including a case portion, a strap and a pair of clipping members. WO2010040754A2, describes a portable stand for a laptop computer to be used by a person who is sitting, lying or reclined, comprising an upturned U-shaped framework for supporting a laptop computer. Other examples include utility shelves that require permanent attachment to an object, such as described in US2006137937, which describes a utility shelf including a housing, a pair of brackets to secure to an object, such as a ladder, and a pair of extendable arms configured to receive large rolls of spooled items such as tape, paper towels, and the like.

Thus, utility shelves known in the art must be permanently attached to an object and are thus, not portable, or the portable utility shelf requires attachment to the user or a bulky framework that isn't easily transported by a user for use in a variety of environments.

The inventor of the present invention has discovered that there is a need for a portable utility shelf that allows a user to quickly and simply attach a utility shelf to an object and to enable a user to efficiently enter data into a laptop in a handsfree mode. Accordingly, if a user must hold a laptop computer in one hand, while being required to input data with the other hand, it is impossible to maintain efficient keyboard entry or perform other curser control (e.g., touch-pad, and attaching interrogation cables to an electric meter). Furthermore, if the user must perform a task (such write handwritten notes) during keyboard entry, it is not suitable to have the laptop connected to the user for use.

The inventor of the present invention has also discovered that there is a need for a portable utility shelf that can easily be manufactured via an injection molding process, wherein only two molds are required to make the base utility shelf article.

Accordingly, what is needed is a simple, easy-to-use, easy-to-transport, easy-to-manufacture, portable utility shelf that is self supportive to aid a user in supporting a laptop in a variety of environments and to perform a variety of tasks.

Exemplary embodiments of the present invention are illustrated in the context of a portable utility shelf for a laptop computer. The skilled artisan will readily appreciate, however, that the materials and methods disclosed herein will have application in a number of other contexts where a portable utility shelf may be used in a variety of different environments to hold a variety of different objects.

Referring to FIG. 1, there is shown a front view of the first shell 100, front sidewall 100a, of the portable utility shelf. The utility shelf comprises a second shell 200 (not shown in FIG. 1) which may be comprised of the same material as the first shell 100. The first shell 100 and second shell 200 may be comprised of different configurations, as shown in FIG. 6. The inventor of the utility shelf found that the configuration of the first shell 100, front sidewall 100a, enables a user to create an adjustable, hands free workstation for an object, such as a lap top. Alternatively, the second shell 200 may have the same configuration as the first shell 100, and thus, the first and second shells may be mirror images thereof, as shown in FIG. 10. This configuration allows the manufacturer to use one mold, twice, thus it may result in a lower cost solution to make the utility shelf.

In one embodiment, the utility, shelf can be comprised of any suitable material known in the art. In one embodiment, the utility shelf is comprised of an injection molded polymeric material. The polymeric material may be selected from a plastic material, such as, a polypropylene homopolymer material. Other plastic materials which would be suitable for fabricating the shelf include PS (polystyrene), CPET (crystalline polyethylene terephthalate), APET (amorphous polyethylene terephthalate), HDPE (high density polyethylene), PVC (polyvinyl chloride), PC (polycarbonate), and foamed polypropylene.

In one embodiment, the utility shelf may contain a pivot shaft 106 to function as a half of a snap hinge and a half sleeve 108 to function as the other half of a snap hinge. In another embodiment, the hinge(s) are integrally molded with and made of the same material as the utility shelf. Any type of hinge known in the art may be used, so long as it is possible to manufacture the hinge via injection molding or the like for production purposes. There are several other methods and types of hinges that can be utilized such as a simple metal hinge, pinned hinge or snap hinge. The hinge system 106/108 allow for the first and second shells to rotate from a closed position to an open position and vice versa.

In another embodiment, the utility shelf may contain a handle 116. In one embodiment, the handle 116 is integrally molded with and made of the same material as the utility shelf. The handle 116 may be molded into the first shell 100 and the second shell 200 of the utility shelf during the manufacturing process. In one embodiment, the handle is formed when the first and second shells are in the closed position. The handle 116 can be configured in any shape, preferably an oval shape.

FIG. 2, there is shown a front view of the first shell 100, back sidewall 200a, of the portable utility shelf. Further to FIG. 1, FIG. 2 shows a plurality of vertical ribs 126 which may be added for strength and support and/or a plurality of horizontal ribs 128 which can be added for strength and support. Accordingly, since the ribs increase the strength and support of the sidewalls, it is possible to use less material in the manufacturing process, thus, resulting in a thinner, lighter weight utility shelf. Furthermore, the ribs may provide a dual function of also creating secure compartments to hold small objects, such as fittings, washers, nuts electrical connecters, etc. In one embodiment, the ribs 126/128 are integrally molded with and made of the same material as the utility shelf.

FIG. 4 there is shown the utility shelf may contain a snap latch, comprised of a first half 118 located on an outer lip 120 of the top of the first shell 100. The other half of the snap latch 118a, shown in FIG. 9, is integrally molded on the top of the second shell 200. The snap latch functions to secure the first shell 100 and the second shell 200 together. In one embodiment, the snap latch is a pressure latch, however, any latch known in the art may be used such as, a push button latch, hasp latch, bolt latch etc. In one embodiment, the first half and the second half of the latch system are integrally molded with and made of the same material as the utility shelf. Also shown in FIG. 4, is an outer lip 120 which can function to align parts together when the utility shelf is closed. The outer lip 120 may also be integrally molded with and made of the same material as the utility shelf.

FIG. 5, there is shown a side view of the utility shelf in a closed position. The shelf may contain a hinge stop (104/110). The stop may be configured as any stop known in the art. The stop functions to inhibit rotation of the hinge system on the first and second shells past a certain point. Thus, in one embodiment, when a user opens the utility shelf, the first and second shells will open at a 90 degree angle. In other embodiments, it is possible for a user to configure the stops so that the first and second shells open at other angles, such as, for example, 180 degrees, 145 degrees, 120 degrees, 100 degrees, 45 degrees or 25 degrees.

FIG. 7 shows the utility shelf open at a 90 degree angle and stops 104 and 110 adjacent to one another. In one embodiment, the hinge stops (104/110) are integrally molded with and made of the same material as the utility shelf.

FIG. 8, there is shown the first shell 100, front sidewall 100a, including at least one attachment object 400a. In another embodiment, a second attachment object 400b, may be included. The attachment object 400a/400b is any object which can attach the shelf to a stationary material. In another embodiment, the attachment object is capable of a quick connect attaching means to an object. In another embodiment, the attachment object is capable of a quick dis-connect from an object. In another embodiment, the attachment object is Capable of a quick connect and dis-connect from an object. In one embodiment, the attachment object is a magnetic material. In another embodiment, the object is a magnet. In another embodiment, the attachment object is a suction cup. The attachment object can be configured to hold any type of weight. In one embodiment, the magnet is a 90 lb pull magnet. In another embodiment, the stationary material is made of metal or an alloy thereof. In another embodiment, the stationary object is any material a suction cup can adhere to, such as glass, metal, or plastic.

The attachment object 400a/400b may be secured to the utility shelf via a slot 112 adjacent a channel 124. In one embodiment, the channel is recessed. In another embodiment, the slot 112 is recessed within the channel 124. The attachment object 400a/400b can be secured by any means that affords the attachment object the ability to be slidably adjustable along the slot 112. For example, the attachment object may be secured with a bolt and nut. The channel 124 may be located on the first shell 100, front side 100a, on the second shell 200, front side, or on both the first and second shell front sides. FIG. 6 shows a utility shelf having channels on only one shell 100. FIG. 10 shows an alternative embodiment 300 where the first shell 100 and the second shell 200 are mirror images thereof and thus channels are located on the both the first shell front sidewall and the second shell front sidewall.

In one embodiment, the channel 124 is configured in a horizontal orientation. In one embodiment, the channel 124 is configured in a vertical orientation.
