DETAILED DESCRIPTION

(17) An illustrative embodiment of the present invention relates to a suspension case having a first cap component, a female-male coupler component, a first elastic film held in tension and spanning flat across the female-male coupler component, a body component, a second elastic film held in tension and spanning flat across the body component, and a base component. Each of the first cap component, the female-male coupler component, the body component, and the base component have an interference fit with an adjacent component to frictionally hold the components together in a predetermined order (first cap component coupled with the female-male component, coupled with the body component, coupled with the base component) to form the suspension case. When the female-male component is pressed together with the body component, the first elastic film is pressed against the second elastic film. An object for display is positioned between the first and second elastic films, and frictionally held in place when the suspension case is fully assembled. The suspension case incudes at least one magnification lens disposed in the first cap component and/or the base component. The at least one magnification lens enables a magnified view of the object for display when it is disposed in the suspension case. The first cap component and/or the base component can be slidably mounted with the suspension case in such a way that the at least one magnification lens can be moved toward or away from the object for display to adjust or vary the focus and/or quantity of magnification via a change in distance from the object for display. The first cap component and/or the base component can additionally and/or alternatively include an illumination source to direct light toward the object for display, thereby illuminating the object.

(18) FIG. 1 through FIG. 9B, wherein like parts are designated by like reference numerals throughout, illustrate an example embodiment or embodiments of a suspension case, according to the present invention. Although the present invention will be described with reference to the example embodiment or embodiments illustrated in the figures, it should be understood that many alternative forms can embody the present invention. One of skill in the art will additionally appreciate different ways to alter the parameters of the embodiment(s) disclosed, such as the size, shape, or type of elements or materials, in a manner still in keeping with the spirit and scope of the present invention.

(19) FIG. 1 and FIG. 2 are side views illustrating a suspension case 10 in accordance with embodiments of the present invention. FIG. 1 shows a fully assembled suspension case 10. FIG. 2 shows separate components of the suspension case 10 in exploded view. A first cap component 12 includes a magnification lens 14 disposed in a top section of the first cap component 12. A first stepped perimeter wall defines a first chamber 15 within interior confines of the first stepped perimeter wall. The first stepped perimeter wall steps inward for a portion, which creates a first male coupler wall 16.

(20) A female-male coupler component 18 has a second stepped perimeter wall 22 having a second at least one vertical side wall defining a second chamber 21 within interior confines of the second stepped perimeter wall 22. The second at least one vertical side wall has an interior wall surface facing the second chamber 21 and an exterior wall surface outside, the exterior wall surface having the second stepped perimeter wall 22. A female coupler portion 23 resides on one half of the female-male coupler component 18 and steps inward with a smaller perimeter wall surface than the exterior wall surface for a portion of the second stepped perimeter wall 22 to form a second male coupler portion 25 of the female-male coupler component 18.

(21) A first elastic film 24 is held in tension and spanning flat across the second chamber 21 of the female-male coupler component 18 and coupled with the second stepped perimeter wall 22.

(22) A body component 26 has a third perimeter wall 32 with a third at least one vertical side wall defining a third chamber 28 and a fourth chamber 33 within interior confines of the third perimeter wall 32. The third at least one vertical side wall has an interior wall surface 29 (see FIG. 6A) facing the third chamber 28 and the fourth chamber 33 and an exterior wall surface outside, the exterior wall surface being the third perimeter wall 32. The interior wall surface 29 is sized and dimensioned for an interference fit with the second male coupler portion 25 of the female-male coupler component 18 and for an interference fit with a third male coupler wall 36 of a base component 34.

(23) A second elastic film 30 is held in tension and spanning flat across the third chamber 28 of the body component 26 and coupled with the third perimeter wall 32. The third chamber 28 and the fourth chamber 33 are separated by the second elastic film 30.

(24) The base component 34 has a bottom 39 and a fourth stepped perimeter wall 36 having a fourth at least one vertical side wall defining a fifth chamber 37 within interior confines of the fourth stepped perimeter wall 36. The fourth at least one vertical side wall has an exterior wall surface external to the fifth chamber 37 and an interior wall surface facing the fifth chamber 37, the exterior wall surface being the fourth stepped perimeter wall 36, which steps inward with a smaller perimeter wall surface than the exterior wall surface for a portion of the fourth stepped perimeter wall 36 that is not in contact with the bottom 39, and which creates the third male coupler wall 35.

(25) When the first male coupler wall 16 of the first cap component 12 is placed within the second chamber 21, the first male coupler wall 16 of the first cap component 12 fits snugly within the second chamber 21 with an interference fit between the smaller perimeter wall surface of the first stepped perimeter wall pressed against the interior wall surface of the second stepped perimeter wall 22. This results in the first male coupler wall 16 and the female-male coupler component 18 being frictionally held together.

(26) When the second male coupler portion 25 of the female-male coupler component 18 is placed within the third chamber 28 of the body component 26, the second male coupler portion 25 of the female-male coupler component 18 fits snugly within the third chamber 28 with an interference fit between the smaller perimeter wall surface of the second stepped perimeter wall 22 pressed against the interior wall surface 29 of the third perimeter wall 32 of the body component 26 and the third chamber 28, and the first elastic film 24 is pressed against the second elastic film 30.

(27) When the third male coupler wall 35 is placed within the fourth chamber 33 of the body component 26, the third male coupler wall 35 fits snugly within the fourth chamber 33 with an interference fit between the smaller perimeter wall surface of the third male coupler wall 35 pressed against the interior wall surface of the body component 34. This results in the base component 34 and the body component 26 being frictionally held together.

(28) FIGS. 4A and 4B show a top view and a side view of the first cap component 12. The magnification lens 14 is incorporated into the first cap component 12. If an object for display 44 is positioned in the suspension case 10, it is placed between the first elastic film 24 and the second elastic film 30 before the female-male coupler component 18 is inserted into the body component 26. Once appropriately placed, the object for display 44 is frictionally held in place between the first elastic film 24 and the second elastic film 30 and is further viewable through the magnification lens 14 down into the suspension case 10.

(29) FIGS. 5A and 5B show a top view and a side view of the female-male coupler component 18. The first elastic film 24 spans across the female-male coupler component 18, and is transparent, enabling viewing through the first elastic film 24. The second stepped perimeter wall 22 is sized, dimensioned, and structured to fit within and enable an interference or friction fit with the third perimeter wall 32 with the third at least one vertical side wall defining the third chamber 28. When the female-male coupler component 18 is placed within the third chamber 28, the first elastic film 24 and the second elastic film 30 are arranged generally planar parallel to each other, and if the female-male coupler component 18 is pressed sufficiently into the third chamber 28 into a fully assembled position, the surface of the first elastic film 24 abuts and makes contact with the surface of the second elastic film 30. In implementations where the object for display 44 is too large, it is possible that the female-male coupler component 18 to not be capable of being pressed into the fully assembled position, but may instead be required to hold in a position that is part way inserted into the third chamber 28. This configuration is acceptable despite not being in the fully assembled position because the interference or friction fit of the female-male coupler component 18 holds the components 18 and 26 together, frictionally, with a gap existing between the first elastic film 24 and the second elastic film 30. However, in most instances, the first elastic film 24 and the second elastic film 30 are capable of flexing and stretching in an elastic manner to enable the object for display 44 to exist sandwiched between the two films 24, 30, with the two films 24, 30 elastically stretched to accommodate the object for display 44 and still be abutting and in contact with each other near their perimeter edges.

(30) A depiction of the fully assembled position with the object for display 44 sandwiched between the first elastic film 24 and the second elastic film 30 is shown in FIG. 3, where the suspension case 10 is depicted in partially exploded view (with the first cap component 12 and the base component 34 not coupled or in fully assembled position with the female-male coupler component 18 or the body component 26, respectively. Further details and operational arrangements of the elastic film 24 relative to the second elastic film 30 as they hold the object for display 44 sandwiched therebetween are not necessary to provide in further detail herein, as they are known by those of skill in the art.

(31) FIGS. 6A and 6B show a top view and a side view of the body component 26. The second elastic film 30 spans across the body component 26. The third at least one vertical side wall has the interior wall surface 29 facing the third chamber 28. The second elastic film 30 provides defining separation between the third chamber 28 and the fourth chamber 33.

(32) FIGS. 7A and 7B show a bottom view and a side view of the base component 34. A second magnification lens 38 is incorporated into the base component 34. If an object for display 44 is positioned in the suspension case 10, it is placed between the first elastic film 24 and the second elastic film 30 before the female-male coupler component 18 is inserted into the body component 26. Once appropriately placed, the object for display 44 is frictionally held in place between the first elastic film 24 and the second elastic film 30 and is further viewable through the second magnification lens 38 into the suspension case 10. It should be noted that the second magnification lens 38 can be provided independent of the magnification lens 14 of the first cap component 12.

(33) FIGS. 8A and 8B show a first cap component 12 having a larger dimension stepped perimeter wall that defines a first chamber 15 within interior confines of the first stepped perimeter wall. The first stepped perimeter wall steps inward for a portion, which creates a first male coupler wall 16 that of a larger dimension than that of the first male coupler wall 16 depicted in earlier figures herein. Also shown is a base component 34 has a bottom 39 and a fourth stepped perimeter wall 36 having a fourth at least one vertical side wall defining a fifth chamber 37 within interior confines of the fourth stepped perimeter wall 36. The fourth at least one vertical side wall has an exterior wall surface external to the fifth chamber 37 and an interior wall surface facing the fifth chamber 37, the exterior wall surface being the fourth stepped perimeter wall 36, which steps inward with a smaller perimeter wall surface than the exterior wall surface for a portion of the fourth stepped perimeter wall 36 that is not in contact with the bottom 39, and which creates the third male coupler wall 35. The third male coupler wall 35 is of a larger dimension than that of the third male coupler wall 35 depicted in earlier figures herein. The function of the larger dimension first male coupler wall 16 and the larger dimension third male coupler wall 35 created a larger length for telescoping out the magnification lens 14 and the second magnification lens 38 further from the object for display 44. As such, in the embodiments illustrated in FIGS. 8A and 8B enable a longer telescoping length for adjusting the focus and magnification of the object for display as viewed through the magnification lens 14 and second magnification lens 38.

(34) FIGS. 9A and 9B show the additional component of a first illumination source 46 and a second illumination source 48. As depicted, the first and second illumination sources 46, 48 direct illuminating light in the direction of the object for display 44 in the interior section of the suspension case 10. Those of skill in the art will appreciate that the illumination sources 46, 48 can be any known form of suitable illumination, such as light emitting diode (LED), incandescent, etc., and can be powered by battery, rechargeable battery, solar panel, or other conventional power source. Further, the first and second illumination sources 46, 48 can both be implemented at the same time, or can independently be implemented as one or the other on the suspension case 10.

(35) The suspension case 10 can be manufactured of a number of different materials. Specifically, the a first cap component 12, female-male coupler component 18, body component 26, and base component 34 can all be made of a number of suitable materials, including plastic, acrylic, polystyrene, composite, or any clear or transparent material, at least with regard to the top and bottom horizontal pieces. The vertical walls, in accordance with certain aspects and embodiments of the present invention, do not need to be clear or transparent. As such, they can be manufactured of additional materials, such as metal, wood, composite, opaque plastic, or the like. The first elastic film 24 and second elastic film 30 can be made of any number of flexible elastic materials, such as polyester (PET) film, thermoplastic polyurethane (TPU) film, or the like. Specific dimensions, thickness, clarity/transparency, and the like are readily determined by those of skill in the art of suspension cases using such elastic films. In addition, the interference friction fit that holds together the components as described can be replaced with conventional latches or other mechanical fastener devices, as would be appreciated by those of skill in the art, such that the present invention is not limited to embodiments relying only on interference fits.

(36) In operation, the object for display 44 is placed onto the second elastic film 30. The female-male coupler component 18 is placed into the third chamber 28 of the body component 26 and slid down toward the second elastic film 30. Depending on how large the object for display 44 is, the female-male coupler component 18 can be slid all the way down until it abuts the second elastic film 30, or part way down as the object for display 44 interferes with and stops the female-male coupler component 18 from moving further. The first cap component 12 is placed into the second chamber 21 of the female-male coupler component 18 and slid down until it abuts the step of the second stepped perimeter wall 22. The base component 34 is placed into the fourth chamber 33 and slid up until it abuts the step of the fourth stepped perimeter wall 36 against the body component 26. Notably, the order in which the base component 34 or the first cap component 12 are coupled with the other components does not matter. Likewise, the order in which any of the components is removably coupled with the other components to form the suspension case 10 also does not matter. The components can be combined in any order, as would be appreciated by those of skill in the art.

(37) Once all components are removably coupled with each other to form the suspension case 10, the suspension case 10 is considered to be in fully assembled configuration (as depicted in FIG. 1, object for display 44 not shown in this figure). In the fully assembled configuration, the object for display 44 is viewable through either or both of the first cap component 12 and the base component 34 because they are both transparent. In embodiments where a magnification lens 14 or a second magnification lens 38 are provided, such magnification lenses 14, 38 enable magnification of the object for display 44. The magnification and focus can be further manually adjusted with the sliding in or out of either the first cap component 12 or the base component 34, as desired, to adjust the focal length to the object of desire 44. Those of skill in the art will appreciate the magnification lenses 14,38 have a perimeter of a sufficient dimension and a height relative to an object for display 44 to provide an appropriate focal length and magnification power to view magnification of the object for display 44 and to provide a larger magnification when a distance of top from the object for display 44 is increased. For example, as those of skill in the art will appreciate, magnification can be selected for the magnification lens 14 or second magnification lens 38 based on variables such as working distance, field of view, eye relief distance, depth of field, and magnification. The magnifying power of a lens depends on its focal length, which depends on the lens curvature. As is known, the greater the curvature, the shorter the focal length and the greater the power. In the selection of a simple, inexpensive magnification lens 14, 38, the lens diameter will typically decrease as the curvature increases to provide higher power. Additional details concerning magnification are not required herein for purposes of enablement as the variables are known and conventional, as such, additional description will not be provided herein. Likewise, in embodiments where the first illumination source 46 or the second illumination source 48 are provided, the object for display 44 is illuminated by turning on the appropriate illumination source 46, 48. Selection of a particular LED with particular low voltage and power source are within the capability of those of skill in the art, thus additional details are not required for purposes of enablement and additional description will not be provided herein. The end result being a transparent suspension case 10 that provides magnification and/or illumination of objects for display 44 placed therein, provided in in a low cost, transportable, suspension case 10, in accordance with the present invention.

(38) As utilized herein, the terms comprises and comprising are intended to be construed as being inclusive, not exclusive. As utilized herein, the terms exemplary, example, and illustrative, are intended to mean serving as an example, instance, or illustration and should not be construed as indicating, or not indicating, a preferred or advantageous configuration relative to other configurations. As utilized herein, the terms about, generally, and approximately are intended to cover variations that may existing in the upper and lower limits of the ranges of subjective or objective values, such as variations in properties, parameters, sizes, and dimensions. In one non-limiting example, the terms about, generally, and approximately mean at, or plus 10 percent or less, or minus 10 percent or less. In one non-limiting example, the terms about, generally, and approximately mean sufficiently close to be deemed by one of skill in the art in the relevant field to be included. As utilized herein, the term substantially refers to the complete or nearly complete extend or degree of an action, characteristic, property, state, structure, item, or result, as would be appreciated by one of skill in the art. For example, an object that is substantially circular would mean that the object is either completely a circle to mathematically determinable limits, or nearly a circle as would be recognized or understood by one of skill in the art. The exact allowable degree of deviation from absolute completeness may in some instances depend on the specific context. However, in general, the nearness of completion will be so as to have the same overall result as if absolute and total completion were achieved or obtained. The use of substantially is equally applicable when utilized in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result, as would be appreciated by one of skill in the art.

(39) Unless otherwise noted or defined herein, to the extent directional vocabulary is utilized, the disclosure and figures are described with reference to a conventional three-dimensional coordinate axis system of X, Y and Z, where the X direction is generally left-right or east-west, the Y direction is generally in-out, relative to the plane of the page of the document, and the Z direction is generally up-down or north-south on the page. Further as utilized herein, the terms horizontal and vertical are utilized consistent with their conventional definitions as would be appreciated by those of skill in the art, and as generally illustrated and expanded upon below. For example, in the fields of physics, engineering, and construction, the direction designated as vertical is usually that along which a plumb-bob hangs in response to the force of gravity. The direction of horizontal is considered along a line or plane that is normal or orthogonal to the vertical plane. As such, moving in a horizontal direction (horizontally) is effectively equivalent to traveling across the earth's surface, e.g., moving forward, backward, left, right, etc., along the ground, while moving in a vertical direction (vertically) is effectively equivalent to moving up (away from the ground) or down (toward or into the ground). Merging the X, Y, Z coordinate access with the terms vertical and horizontal, the Z-axis lies in the vertical direction and the X and Y axes lie in the horizontal plane with the vertical Z axis being orthogonal thereto.
