Device Casing With Built-in Retractable Mechanism

Abstract

A protective casing for a mobile computing device includes a retractable mechanism integrating a thin, sliding, front surface cover with a fixed back panel. The retractable assembly includes a substantially robust spring torsion system secured on a metallic shaft at one end, and on a cylindrical barrel at the other. In one arrangement, this design allows the front panel of the case to slide open laterally with a slight prod, exposing the display screen of the device. In yet another arrangement, the front panel can be drawn back to a closed position by a minimal pull to the reverse direction until it unites with a locking mechanism at the opposite end. The casing is molded in a manner that it follows the shape of the device and allows strategically placed cut-outs to be created for easy access to the device's side buttons, openings and slots.

Description

FIELD OF THE INVENTION

[0001] The invention relates to the field of mobile computing devices, and in particular, to a protective casing for a mobile device including a retractable barrel mechanism that is integrally formed with the casing. These storage casings serve to guard the mobile devices from bumps, dents, scratches, falls and other minor collisions that are likely to be encountered from daily use. They also serve to protect devices from harsh weather conditions and other external elements.

BACKGROUND OF THE INVENTION

[0002] In this era of new technology, the evolution of digital portable devices is continuously accelerating with newer gadgets getting more sophisticated and feature-packed. Mobile phones, digital cameras, laptops, multimedia players and other electronic devices are steadily developing as functions from one device are incorporated into the other, resulting in the introduction of more advanced gadgets. These devices have been intricately manufactured to deliver extra powerful features, albeit making it more fragile, thus increasing the demand for sturdy protection whilst maintaining ease of handling and use.

[0003] The market thrives with multiple casing designs that offer varying levels of protection while serving as a storage unit. However, some of these designs have current limitations, including the need for users to remove the casing before gaining access to the device's buttons or keys. Although some casings may allow for the device to be operated without removal, these are typically designed with a flap cover, making it undesirable and impractical for everyday use.

[0004] The retractable front cover design substantially addresses the constraints noted above, while still providing ample protection and storage capabilities.

BRIEF SUMMARY OF THE INVENTION

[0005] In accordance with the invention, a retractable torsion mechanism is incorporated integrally into the portable casing, allowing the front cover to slide in a lateral motion and provide user access to the device screen. The invention can be scaled to fit any handheld, portable device. It can be made by light-weight and durable materials, having a sturdy exterior and a soft internal lining to prevent scratches to the device and offer shock-absorbing mechanism. Individual openings for external buttons, pin connector slots, attachments and the like are also provisioned and can be fully customized. This invention combines convenience with practicality. It allows for devices to be used without removal, with very little addition to the device size and weight, and its unique retractable front panel permits it to be used practically anywhere.

[0006] Compared with other cases currently available in the market, this invention truly stands out, having the distinct combined advantage of convenience and portability. This is made possible by the torsion-technology via the retractable torsion barrel. The invention's opening and closing mechanical actuations is integrally engineered with the body of the invention. As such, this unique feature distinguishes the invention from traditional device casings, as there are no obtrusive mechanisms like hinges, flaps, zippers, magnetic contacts, buttons, Velcro straps and the like.

[0007] The invention's front panel slides in a lateral motion, opens and closes with a slight prod/push of a finger, providing access to the device's display screen. The panel slides via slots transversally located of the casing, running its entire length. These slots guide the panel's lateral motion every time the case is opened and closed. Opening the case, the front panel slides smoothly, rolling flush into the torsion spool/barrel. This action reveals the device's display screen and permits the user to freely operate the device without removal from the case. Reversing the action slides the panel back in the closed position. Latching mechanisms secure the front panel firmly in position.

[0008] Further features of the invention, its nature and various advantages will be more apparent from the accompanying drawings and the following detailed description of the preferred embodiments.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The foregoing summary, as well as the following detailed description of the invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, there are shown in the drawings embodiments which are presently preferred. It should be understood, however, that the invention is not limited to the arrangement and instrumentalities shown.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Referring to FIG. 1 is an isometric representation of the casing according to the present invention, including the retractable mechanism. It shows the product (1) the retractable torsion barrel (2), and the sliding front panel (3). Openings for external buttons (4), speakers (5) and auxiliary ports (6) are also provided. Slots (7) transversally located of the invention guide the front panel's lateral sliding motion.

[0011] Referring to FIG. 2 shows the invention's top view. It shows the retractable torsion barrel (2) and the front panel (3). The procedure for opening and closing the invention is narrated thus. As the front panel (3) opens from the closed position, it smoothly slides and rolls into the retractable barrel (2) enabled by the torsion spring (9). This provides convenient user access to the device's display screen inside the invention. Any device secured within the invention can, thus, be conveniently used without removal. Closing the front panel (3) is through the reverse direction. The front panel (3) smoothly slides out of the retractable barrel and back in its original position, securing the device within the invention. The torsion system, therefore, integrates convenience, portability and ease of use. The torsion spring (9) can also be viewed in this diagram mounted on a metal shaft (10) positioned longitudinal of the torsion barrel (2).

[0012] Referring to FIG. 3 shows the longitudinal-section diagram of part of the torsion barrel (2) assembly. The torsion barrel (2) is composed of an aluminum barrel housing (8) and a thin torsion spring (9). The torsion spring (9) is mounted on a fixed metal shaft (10) positioned longitudinal of the torsion barrel (2). The retractable action is made possible through the stored mechanical energy in the torsion spring (9).

[0013] FIG. 4 is a cross-sectional diagram of the torsion barrel (2). The torsion barrel (2) is encased in a lightweight and sturdy aluminum barrel housing (8). The cross-section view of the metal shaft (10) can also be seen in this diagram.
