[0034] In the following Detailed Description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. Directional terminology, such as top, bottom, front, back, leading, trailing, etc., is used with reference to the orientation of the Figure(s) being described. Because components of embodiments of the present invention can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0035] The present invention discloses a storage and protection assembly for transporting containers which may contain hazardous materials. In one embodiment the containers can be gas cylinders. Although one of ordinary M the art will understand that the type of container which the protection assembly can be designed for will vary and such modifications are within the scope of this invention.

[0036] As can be seen in FIGS. 1 and 2, in one embodiment of the present invention, the storage and protection assembly is comprised of: [0037] a body 100 with an internal hollow portion for storing a container 50, said body having a bottom side 102 and a top side 104; [0038] a cap 300 which is adapted to fit within the internal hollow portion of the body 100 at said top side 104; [0039] wherein said cap 300 has a primary 320 and a secondary locking mechanism 340; [0040] wherein the primary locking mechanism comprises threaded channels 320 on the outer walls of the cap; [0041] wherein the secondary locking mechanism 340 comprises a plurality of spring assisted assemblies 400 which are movable from a unlocked position to a locked position; [0042] wherein the body 100 of the storage assembly has a plurality of cavities 220 circumferentially located in the top side of the internal hollow portion; and [0043] wherein the plurality of spring assemblies 400 are adapted to slide into the plurality of cavities 220 when the secondary locking mechanism 340 is in a locked position.

[0044] More particularly, FIG. 1 illustrates a cross-sectional view of a body 100 of the storage and protection assembly of the present invention. The body 100 has an internal shape which is capable of accepting and storing a gas cylinder 50 for storage and transport purposes. As can be seen in FIG. 1, the body 100 should be of the size so that a gas cylinder 50 should comfortably fit within the body 100, with some space between the walls of the body 100 and the gas cylinder 50.

[0045] The body 100 has a bottom side 102 and a top side 104, which forms the entrance where the gas cylinder can enter through and also where the cap 300 (FIG. 2) can be fitted so as to enclose the gas cylinder 50 within the body 100 for storage and protection. The top side 104 of the body 100 has threaded channels 200 located on the internal walls. These threaded channels 200 correspond and engaged with threaded channels 320 located on the cap 300, and make up the primary locking mechanism of this assembly.

[0046] Moving now to FIG. 2, the cap 300 of the assembly is comprised of a shape which aligns with the shape of the body 100, and the cap is designed to fit within the internal top side 104 of the body 100. The sides of the cap are shaped to fit around the cylinder 50 contained in the body 100. The cap 300 contains a primary locking mechanism, and a secondary locking mechanism 340. As described above the primary locking mechanism is comprised of the threaded channels 320 located on the outer walls of the cap 300. The secondary locking mechanism 340 is comprised of spring assisted assemblies 400 which can be seen in FIGS. 3 and 4 and will be described in more detail below.

[0047] As can be seen in FIG. 2, the cap 300 had a central handle 350. A top view of this is also shown in FIG. 3. The central handle is responsible for actuating the secondary locking mechanism 340, either in a locked or unlocked position. The cap 300 has a plurality of internal channels, as can be seen in both FIGS. 2 and 3. The internal channels are where the spring assisted assemblies 400 reside (for purposes of simplicity the spring component is not shown in FIGS. 2 and 3, hut can be seen in detail in FIG. 4). As can be seen the internal channels are disposed throughout the cap, each channel having a spring assisted assembly 400 residing therein. The internal channels run have an opening on the sides of the cap 300, so that the spring assisted assemblies 400 can slide out of the cap 300 when it is time to engage the secondary locking mechanism 340.

[0048] In one embodiment the central handle 350 is configured to be pressed down towards the body 100 to engage the secondary locking mechanism 340 to a locked position, and to be pulled upwards away from the body to disengage the secondary locking mechanism to an unlocked position. Disengaging the secondary locking mechanism 340 through upward movement of the central handle causes the spring assisted assemblies 400 to retract away from the plurality of cavities 220 contained in the body 100 and rest within internal channels disposed throughout the cap 300.

[0049] Moving now to FIG. 3, a top cross-sectional view of the cap 300 is shown. As can be seen in this embodiment the cap contains about 6 spring assisted assemblies 400 disposed equidistantly throughout the cap 300. The internal channels where the spring assisted assemblies 400 reside have a narrowed portion and an enlarged portion. The internal channels can have any cross-sectional shape desired, for example, cylindrical, square or rectangular, although a preferred shape is cylindrical. This also corresponds to the shape of the stopper 430, and the cavities 220. All three of these components preferably have the same cross-sectional shape as for purposes of ease of fit in and out while the secondary locking mechanism 340 is engaged and disengaged during operation.

[0050] As can be seen in FIG. 3, the narrowed portion of the internal channels due to its geometry and narrowed cross-section, confines the spring assisted assemblies 400 within the internal channels. Once the central handle 350 is pulled upwards to disengaged the spring assisted assemblies 400 and retract the stopper 430 from the cavities 220 and back into the internal channel, the narrowed portion of the internal channels acts as a stopping point for the spring assisted assemblies so that the stopper 430 cannot be pulled out of the internal channels as the central handle 350 is being pulled upwards.

[0051] As can be seen in FIGS. 3 and 4, in one embodiment the spring assisted assemblies 400 are comprised of a metal wire 450, a stopper 430 and a spring 440 (only shown in FIG. 4). The metal wire 450 is coupled to the stopper 430, and the spring 440 resides around the metal wire 450. The metal wire 450 is also coupled to a central handle 350 of the cap 300, on the opposite side from the stopper 430 side.

[0052] The stopper 430 can have a cylindrical, square or rectangular shape, although preferably a cylindrical shape. Each component of the spring assisted assemblies 400, including the wire 450, the stopper 430 and the spring 440 are preferably comprised substantially of a metal material, although other materials having sufficient strength and resilience can be envisioned and will be known to those skilled in the art. The central handle 350 is also preferably comprised of the same material of the spring assisted assembly as it is connected to the assemblies 400 and requires resiliency and sturdiness. A metal material is preferred for this purpose, for example steel.

[0053] During operation of the secondary locking mechanism 340, for purposes of engaging the locking mechanism 340, the spring assisted assemblies 400 are placed in a locking position by engaging with the plurality of cavities 220 circumferentially located in the top side 104 of the internal hollow portion of the body 100. This is accomplished by stoppers 430 sliding into the plurality of cavities 220 so as to engage the spring assisted assemblies 400 into a locked position, thereby actuating the secondary locking means of the cap 300 and body 100 together. Therefore in a locked position the central handle 350 is pressed down, and this motion pushes the metal wire 450 outwardly from the cap, and also pushes the stopper 430 attached to the wire 450 outwardly towards and into the cavities 220 contained on the internal walls of the body. As can be understood, for this locking motion to work, the plurality of cavities 220 and the spring assisted assemblies should be the same number. For example in the Embodiment shown in FIG. 3 there are six spring assisted assemblies 400 depicted. This would necessitate that in the body 100 shown in FIG. 1, there would also need to be six cavities 220 corresponding with the number of spring assisted assemblies 400.

[0054] If a user wishes to unlock or disengage the secondary locking mechanism 340, then the user would have to pull upwards on the central handle 350, and this retracts the stoppers 430 from cavities 220 and back into the internal channels contained within the cap. The narrowed portion of the internal channels as can be seen in FIG. 3, acts as a barrier and does not allow the stopper to be pulled further up within the internal channel. The spring 440 also assists in this. It is because of spring 440 that the central handle 350 will not spontaneously disengage during for example a collision or of the body 100 gets damaged in any way. The stopper 430 should be of a size so that it can comfortably fit within the internal channels and the cavities 220, therefore its cross-sectional size should be less than that of the internal channels and cavities 200, and enough so as to avoid friction between the walls during engaging and disengaging of the secondary locking mechanism 340.

[0055] The combination of the primary locking mechanism containing the threaded channels 320 on the cap and threaded channels 200 on the body, in addition to the secondary locking mechanism 340 provide a dual locking means for the assembly of the present invention, which protects the contents within and does not allow for the contents to be accidentally dislodged from the container, thus protecting them during transport. This is particularly important in terms of dangerous materials such as those typically contained in gas cylinders.

[0056] The body 100 of the assembly is preferably composed of a sturdy material, including but not limited to a polymeric material, a metal material, reinforced material, a combination of metal and polymer material, and other such known materials which will be apparent to one of ordinary skill in the art.

[0057] In one embodiment, the body 100 of the assembly includes an internal bottom portion which comprises a resilient design. This can include an upwardly curved surface or raised bottom portion (not shown) which will adapt to the shape of a bottom section of a gas cylinder 50. Additionally, or alternatively, the bottom portion of the body 100 can also include a plurality of springs (not shown), which placed throughout the bottom section and are disposed and movable vertically within the bottom portion, so that the cylinder does not have impact with the bottom portion during movement and transport of the assembly, but rather is cushioned instead by the motion of the springs underneath it.

[0058] In a further embodiment, the body 100 of the present invention can also further comprise a layer of a reinforcing material on the internal walls, either within the walls and/or on the surface of the walls. This reinforcing material can be dispersed throughout the body in a lattice configuration, a matrix, a repeating or a randomized pattern configuration. The reinforcing material placed throughout the body's internal walls can be selected from a polymer, a polymer composite, a metal, a metal wire, a reinforced fiber, inorganic fibers, and a metal polymer composite.

[0059] While particular embodiments of present invention have been shown and described, it is apparent that changes and modifications may be made therein without departing from the invention in its broadest aspects. Various combinations of these embodiments can be made. The aim of the appended claims, therefore, is to cover all such changes and modifications as fall within the true spirit and scope of the invention.
