Richardson describes another dry storage box in U.S. Pat. No. 6,646,864, “Protective Case for Touch Screen Device” issued Nov. 11, 2003, which is incorporated herein by reference, as a protective case for an electronic device that has a touch screen, wherein the protective case has a membrane adapted to the specific contour and profile of the electronic device that allows the user to use the touch screen interface. The protective case taught by Richardson also allows infrared and other communication signals while the device is secured inside the case. Electrical connections can also be made through the case.
The present invention is seal for a viewing and operating window formed in a cover of a dry storage box having structure therein for securing a normally handheld portable electronic device adjacent to a floor thereof with the device's display and control key pad facing toward the window and in close proximity thereto.
According to one aspect of the invention, the window aperture is formed in the dry box cover with a rigid and continuous inner peripheral frame formed of the cover material and having a continuous substantially planar surface, the window is formed of a membrane of flexibly resilient plastic material and sized to substantially fill the window aperture, the membrane including an optically transparent interior portion that is structured for viewing the device's display and control key pad there through, and a continuous peripheral seal portion surrounding the interior portion that is relatively thicker than the interior viewing portion, the continuous peripheral seal portion is sized to engage the inner peripheral frame of the window aperture; and a clamping mechanism that is structured for clamping the peripheral seal portion of the membrane against the inner peripheral frame of the window aperture in a continuous substantially water-resistant relationship therewith.
According to another aspect of the invention, the clamping mechanism includes a window sash that has an outer periphery that is larger than the window aperture and an inner peripheral lip that is substantially the same as the window aperture and the window sash is formed with a substantially planar contact surface positioned between the inner peripheral lip and the outer periphery; and a securing mechanism that is structured for securing the window sash to the cover with the continuous peripheral seal portion of the membrane compressed between the window sash contact surface and the planar surface of the window aperture inner peripheral frame.
According to another aspect of the invention, the securing mechanism includes several fasteners securing the window sash to the cover. Alternatively, the securing mechanism includes several rigid clips securing the window sash to the cover.
According to another aspect of the invention, the clamping mechanism includes a continuous circumferential ridge formed on the inner peripheral frame of the window aperture, and a continuous circumferential slot formed in the relatively thicker peripheral seal portion of the membrane, the circumferential slot is structured to couple the peripheral seal portion to the circumferential ridge in a continuous substantially water-resistant relationship therewith.
Optionally, the circumferential ridge is formed with one or more continuous teeth that are projected outwardly away from a main body of the ridge and out of the plane of the inner peripheral frame of the window aperture, and the circumferential slot has an equal number of continuous circumferential grooves that are sized to engage the circumferential teeth of the ridge under a slight compressive force.
According to another aspect of the invention, the flexibly resilient plastic material of which the membrane is formed is a substantially optically transparent polyvinylchloride (PVC) material, or another suitable plastic that is injection moldable in thin interior sheet portions that are substantially optically transparent and is simultaneously injection moldable in continuous peripheral portions that are thicker than the interior sheet portions.
Other aspects of the invention are detailed herein.
The foregoing aspects and many of the attendant advantages of this invention will become more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
In the Figures, like numerals indicate like elements.
The dry box 100 is generally of a type well-known in the art and generally includes a pair of mutually hinged bottom and top covers 102, 104, hereinafter a “container” 102 and “lid” 104. The container 102 is, by example and without limitation, a substantially rectangular open box with the similarly shaped sealing lid 104 hinged thereto. The container 102 and lid 104 are both constructed of light weight, substantially rigid, water-resistant material, such as heavy gauge injection-moldable plastic or another suitable material, such as metal, and may be designed for rugged industrial use, recreational use, commercial use, or many other uses. Alternatively, one or both the container 102 and lid 104 are formed of a resiliently pliable material, such as a flexible rubber, for an application in a wet environment. The container 102 and lid 104 are mutually structured for creating a substantially water-resistant circumferential door seal mechanism 105 between respective peripheral lip portions 106, 108 formed around their respective openings. The substantially water-resistant circumferential seal mechanism 105 is, by example and without limitation, a gasketed seal of the type disclosed by Jinkins in U.S. Pat. No. 4,298,204, “Seal” issued Nov. 3, 1981, which is incorporated herein by reference. A latch mechanism 110 secures the lid 104 in a substantially water-resistant sealed relationship with the container 102. According to one embodiment of the invention, the latch mechanism 110 is an elastic cam-over latch mechanism. Such latch mechanisms are generally well-known and include, by example and without limitation, a snap latch closure of the type disclosed by Swanson in U.S. Pat. No. 5,295,60, “Housing With Snap Latch Closure” issued Mar. 22, 1994, and the pivoting clasp disclosed by Owens, et al. in U.S. Pat. No. 5,641,065, “Medical Instrument Soaking, Transporting and Storage Container” issued Jun. 24, 1997, both incorporated herein by reference.
The lid 104 includes an optical magnification mechanism or optical magnifier 112 that, when the lid 104 is closed relative to the container 102, is positioned behind an opening or window aperture 113 that is positioned and structured for viewing an interior portion of the container 104 there through. The window aperture 113 is just as easily formed in the container 102 with the optical magnifier 112 positioned there behind, so that the roles of the two covers 102, 104 are reversed, and the window aperture 113 is positioned and structured for viewing an interior portion of the lid 104. In one example, the window aperture 113 is formed in a plate or floor portion 114 of the lid 104, and the magnifier 112 is positioned in the window aperture 113 for enlarging the appearance of a display portion D of a normally handheld portable electronic device E (shown in
A pair of mating eyelets 118, 120 are optionally provided on the respective lip portions 106, 108 adjacent to the latch mechanism 110. The mating eyelets 118, 120 come together when the lid 104 is close relative to the container 102 and form a ring 121 for receiving the shackle of a padlock for securing the contents of the dry box 100 against theft. Alternatively, the ring 121 receives a lanyard or wrist strap for maintaining a hold on the dry box 100 and its contents.
Alternatively, the Fresnel lens magnifier 112 formed of a thin resiliently pliable membrane that operates magnify the appearance of both the display D and control key pad P of the electronic device E. For example, the Fresnel lens magnifier 112 is a sheet of flexible magnifying plastic of a type that is well-known in the art. See, for example, U.S. Pat. No. 3,140,883, “Book Cover” issued to Anthony on Oct. 23, 1962, which is incorporated herein by reference. See, also, U.S. Pat. No. 4,828,558, “Laminate Optic with Interior Fresnel Lens” issued to Kelman on May 9, 1989, and U.S. Pat. No. 4,848,319, “Refracting Solar Energy Concentrator and Thin Flexible Fresnel Lens” issued to Appeldorn on Jul. 18, 1989, which are both incorporated herein by reference. The Fresnel lens magnifier 112 is thus made substantially flexible so that, when the Fresnel lens magnifier 112 is in close proximity to or even in direct contact with the electronic device E, substantially normal finger pressure is effective for communicating tactile inputs to the electronic device E, i.e., depressing the keys of the control key pad P.
The substantially water-resistant circumferential seal 105 along respective peripheral lip portions 106, 108 around the openings of the respective container 102 and lid 104 is illustrated, by example and without limitation, as a circumferential projection or tongue 123 formed in the peripheral lip 106 of the container 102 and a mating circumferential groove or channel 124 formed in the peripheral lip 108 of the lid 104, the channel 124 is sized to receive the tongue 123. A gasket 126 of a resiliently deformable and substantially water-resistant material, such as rubber, silicone, or closed-cell foam, is positioned at least partially within the channel 124 and is sized to cooperate with the tongue 123 and channel 124 so that the tongue 123 contacts and partially deforms the gasket 126 when the lid 104 is closed relative to the container 102 with the latch mechanism 110 engaged.
An interior cavity 128 of the container 102 is sized to receive and contain one or more different normally handheld portable electronic device adjacent a floor 130 thereof. Additionally, the container floor 130 includes receiver structure 132 for securing the container 102 to an external presentation apparatus, such as the universally positionable ball-and-socket mounting apparatus A of the type illustrated in
Occasionally, it is desirable to connect the portable electronic device to an external antenna or power source. Accordingly, the container floor 130 optionally includes a knock-out plug 136 that, when removed, leaves an aperture sized to admit a wire, plug or wiring harness there through so that direct electrical connections to be made electronic device E without having to open the lid 104. The aperture left by removal of the plug 136 also provides a pass-through for light, acoustics, heat, mechanical actuation, and other forms of communication with the device E. The knock-out plug 136 is placed at the bottom of a well 138 and includes a groove 140 formed thereabout that locally thins the floor 130 and permits a user to punch out the knock-out plug 136 with thumb pressure or a light hammer and leaves an edge that is harmless to insulated wires.
Further, the glass, acrylic, plastic, or polycarbonate, or other transparent material of magnifier 112 allows infrared and other types of communication signals between the electronic device E inside the case and an external electronic device while the device E is maintained in the protective dry box 100.
According to one embodiment of the invention, the portable electronic device E is located relative to the window aperture 113 and is secured adjacent the container floor 130 by a resilient adhesive pad 142 commonly known as a Pressure Sensitive Adhesive or PSA. Other suitable means for removably or permanently securing the portable electronic device E are considered equivalent and are also within the scope of the claimed invention. For example, snap-in clips may be molded in the container 104 for securing the portable electronic device E, or a custom bracket, or a fastener, or a hook and loop fastener system, or even foam pads having cut-out or molded features sized to accept different portable electronic devices of different sizes and shapes. Different means for locating and securing the portable electronic device E can be provided in the container 104 without deviating from the scope and intent of the present invention.
The container 102 and lid 104 are sized compatibly with the portable electronic device E to ensure the magnifier 112 is spaced a distance L from the display D, whereby the magnifier 112 is both focused on the display D and provides significant magnification of the display D when the dry box 100 is about arm's length from the user's face. For example, the magnifier 112 magnifies the display D about 150 percent or more when the dry box 100 is positioned about arm's length from the user's face, but may be any desired magnification which makes information appearing on the display D appear larger, and therefore, easier to view.
According to one alternative embodiment of the invention, the magnifier 112 is initially separate from the lid 104, and the magnifier 112 is subsequently positioned over or in the window aperture 113 and coupled to the lid 104 with a substantially water-resistant seal 144 between the magnifier 112 and lid 104. By example and without limitation, the seal 144 is formed using a suitable adhesive such as a conventional room temperature vulcanizing (RTV) silicone rubber composition containing in general a cross-linkable polymeric, usually linear siloxane, a compound that has a vulcanizing effect, a catalyst and optionally other additives, like plasticizers, bonding agents, pigments, processing agents and fillers. Such adhesive RTV silicone rubber compositions are generally well-known, as disclosed by Schoeley, et al. in U.S. Pat. No. 5,969,057, “Adhesive RTV Silicone Rubber Compounds” issued Oct. 19, 1999, which is incorporated herein by reference. Other adhesives are also contemplated for forming the substantially water-resistant seal 144 and can be substituted for the RTV without deviating from the scope and intent of the present invention. Alternatively, the magnifier 112 is ultrasonically welded to the lid 104 to form the substantially water-resistant seal 144.
When the knock-out plug 136 is punched out and removed, the well 138 is transformed into an aperture that extends though the container floor 130 that is sized to admit a wire, plug or wiring harness there through and has an inside edge 146 that is harmless to insulated wires.
The Fresnel lens is known to be structurable to have a shorter focal length than a conventional convex lens for a similar degree of magnification. As a result, the container lid 104 is optionally lower in profile when the magnifier 112 is structured as the Fresnel lens, than when structured as the conventional convex lens. Therefore, the container 102 and lid 104 are sized compatibly with the portable electronic device E to ensure the Fresnel lens magnifier 112 is spaced a shorter distance l from the display D, whereby the Fresnel lens magnifier 112 is focused on the display D while providing significant magnification of the display D when the dry box 100 is about arm's length from the user's face. The distance l that the Fresnel lens magnifier 112 is spaced from the display D is less than the distance L (shown in
The magnifier 112 is movable relative to the window aperture 113 such that the optically transparent normal-viewing window 148 is accessible to the user. By example and without limitation, one of the sidewalls 150 of the magnifier 112 is hinged along one edge of the sealing lid 104 by a conventional rotational lid hinge 154 of a type well-known in the art. The hinged magnifier 112 is thus easily swung aside to expose the normal-viewing window 148, and is also easily swung into place over the normal-viewing window 148 to magnify the display D. According to one embodiment of the invention, the hinged magnifier 112 is latched in place over the normal-viewing window 148 by a catch mechanism 156 that includes, by example and without limitation, a conventional recess or detent 158 in the lid 104 and a mating tongue 160 formed along an edge of one of the sidewalls 150 of the hinged magnifier 112. Other conventional catch mechanisms are also contemplated and can be substituted without deviating from the scope and intent of the present invention.
Alternatively, the optically transparent normal-viewing window 148 in the window aperture 113 is a thin optically transparent resiliently pliable membrane without magnification that operates as a normal viewing window for viewing both the display D and control key pad P of the electronic device E. Simultaneously, the optically transparent membrane-type normal-viewing window 148 operates as a touch screen for operating the portable electronic device E. For example, the normal-viewing window 148 is a substantially planar thin optically transparent plastic sheet or film of a material, such as silicone, that is sufficiently transparent to permit substantially unimpeded viewing of the display D and yet remains flexible, even at extreme cold temperature, so that substantially normal finger pressure is effective for communicating tactile inputs to the electronic device E, i.e., depressing the keys of the control key pad P. Alternatively, it is known that polyvinylchloride (PVC) material at 0.010 inch to 0.015 inch thickness gives acceptable results. However, the membrane-type window 148 is optionally formed of another commercially available flexible material in different plastic families of resins that provide suitable results. According to one embodiment of the invention, however, the material of the membrane-type window 148 is on the order of 0.030 inch to 0.060 inch thick, which provides a ruggedness and durability that is desirable both for long product life and for protecting the electronic device E contained in the dry box 100. It is also known that PVC material at 0.060 inch to 0.150 inch thickness for the material of the membrane-type window 148 gives acceptable results, whereby the substantially normal finger pressure is effective for communicating tactile inputs to the electronic device E by depressing the keys of the control key pad P, and the material remains sufficiently flexible that, after depressing a key, the material resiliently returns to its original pre-depressed substantially planar condition. Such rugged and durable thicknesses is not believed to provide a membrane-type window 148 sufficiently flexible to allow tactile inputs to be communicated to a touch screen type electronic device, as described by Richardson in U.S. Pat. No. 6,646,864, “Protective Case for Touch Screen Device” issued Nov. 11, 2003, the complete disclosure of which is incorporated herein by reference. Rather, the thicker PVC material is used with electronic devices E of the type that use button-type keys for the control key pad P. Furthermore, unlike the membrane taught by Richardson in U.S. Pat. No. 6,646,864, the membrane-type window 148 of the present invention is intended to be universal as regards different electronic devices E; therefore, the membrane-type window 148 is not fitted to the button-type keys for the control key pad P, but is a substantially planar sheet. Thus, unlike the membrane taught by Richardson in U.S. Pat. No. 6,646,864, the membrane-type window 148 of the present invention does not include special features such that the buttons on the PDA are easily operated through the protective membrane provided by the membrane-type window 148, nor special features to aid the user in pressing the buttons. The membrane-type window 148 of the present invention does not include dimpled areas for the user's finger located directly over the buttons, nor does it include a section of membrane defined by a thinner area around the section for enabling the user to more easily deflect the section of membrane over the button.
The normal viewing transparent membrane-type window 148 also remains sufficiently resilient to return to it pre-depressed condition when the finger pressure is removed. Such resilient transparent membranes for forming the membrane-type window 148 are generally well-known, as disclosed by Wong, et al. in U.S. Pat. No. 6,614,423, “Touch-Pad Cover Protecting Against Wear, Spills and Abuse” issued Sep. 2, 2003, which is incorporated herein by reference; and Richardson in U.S. Pat. No. 6,646,864, which discloses a protective case for an electronic device that has a touch screen, the protective case having a membrane adapted to the specific contour and profile of the electronic device that allows the user to use the touch screen interface, the complete disclosure of which is incorporated herein by reference. The combination of container 102 and lid 104 is lower profile even than the dry box 100 having the Fresnel lens magnifier 112, such that the resilient transparent membrane of the window 148 is in close proximity to, or even in direct contact with, the device control key pad P. Accordingly, an overall depth d of the container 102 and lid 104 combination is the same depth or only slightly deeper than an overall thickness t (shown in
The resiliently pliable, optically transparent membrane-type window 148 permits normal viewing and operation of the portable electronic device E within the dry box 100. The magnifier 112 provides significant magnification of the display D. By example and without limitation, the magnifier 112 is spaced above the lid 104 and the resiliently pliable, optically transparent membrane-type window 148 in the window aperture 113. The magnifier 112 is aligned with the window aperture 113 at a distance above the resiliently pliable and optically transparent membrane-type window 148 in the window aperture 113 that effectively spaces the convex lens magnifier 112 at the distance L from the display D and control key pad P of the electronic device E, or that spaces the Fresnel lens magnifier 112 at the distance l from the display D and control key pad P.
The magnifier 112 is movable relative to the membrane-type window 148 such that the resiliently pliable, optically transparent membrane-type window 148 is available to the user's fingers for manipulation of the control key pad P. By example and without limitation, the sidewall 150 of the magnifier 112 is hinged along one edge of the sealing lid 104 by the conventional lid hinge 154 of a type well-known in the art. The hinged magnifier 112 is thus easily swung aside to expose the transparent membrane of the window 148, and is also easily swung into place over the transparent membrane-type window 148 to magnify the display D. According to one embodiment of the invention, the hinged magnifier 112 is latched in place over the transparent membrane-type window 148 in the window aperture 113 by the catch mechanism 156 or another conventional catch mechanism.
The magnifier 112 is movable relative to the resiliently pliable, optically transparent membrane-type window 148 by sliding relative to the floor 114 of the lid 104 by means of a sliding mechanism 161. By example and without limitation, the lid 104 is formed with a pair of rails 162 along opposing edges. The sidewalls 150 of the sliding magnifier 112 are both formed with mating tongues 164 that fit into the rails 162. The sidewalls 150 space the tongues 164 an appropriate distance from the lens portion 152 of the magnifier 112. The rails 162 and mating tongues 164 are structured to cooperate in a manner that permits the sliding magnifier 112 to slide along the rails 162 relative to the container lid 104. Optionally, the sliding magnifier 112 is removable from the lid 104 by continuous sliding of the sidewalls 150 along the rails 162 until the tongues 164 disengage from the rails 162. The sliding magnifier 112 is replaceable on the lid 104 by re-engaging the tongues 164 with the mating rails 162 and sliding the magnifier 112 into position over the window aperture 113.
Alternatively, the non-magnified normal-viewing window 148 in the window aperture 113 of the lid 104 is formed as the thin transparent resilient membrane without magnification that operates as a touch screen for operating the portable electronic device E. The magnifier 112 is spaced the appropriate distance above the window aperture 113 of the lid 104 and the optically transparent membrane of the membrane-type window 148 for viewing the display D at the desired magnification. The magnifier 112 is either the conventional convex lens, the Fresnel lens, or another magnifying lens capable of magnifying the display D of the electronic device E. The magnifier 112 is movable relative to the window aperture 113 and the optically transparent membrane-type window 148 by sliding on the rails 162 relative to the floor 114 of the lid 104. The sliding magnifier 112 is thus moved to permit access to the window 148.
The magnifier 112 is a sheet of flexible magnifying plastic of a type that is well-known in the art. See, for example, U.S. Pat. No. 3,140,883, “Book Cover,” which is incorporated herein by reference. See, also, U.S. Pat. No. 4,828,558, “Laminate Optic with Interior Fresnel Lens,” and U.S. Pat. No. 4,848,319, “Refracting Solar Energy Concentrator and Thin Flexible Fresnel Lens,” which are both incorporated herein by reference. The sheet magnifier 112 is thus made substantially flexible. The lens portion 152 of the flexible sheet magnifier 112 is optionally a conventional convex lens (shown), a Fresnel lens, or another magnifying lens suitable for optically magnifying the display D of the electronic device E.
The flexible sheet magnifier 112 is coupled to the lid 104 by an edge hinge joint 166 that is formed, by example and without limitation, using an adhesive such as an RTV adhesive or another suitable adhesive between the lid 104 and one edge 168 of the flexible sheet magnifier 112. Alternatively, the edge hinge joint 166 between the flexible sheet magnifier 112 and the lid 104 is formed by ultrasonically welding the edge 168 of the flexible sheet magnifier 112 to the lid 104. The flexible sheet magnifier 112 is operable like a cover of a book, i.e., it is grasped along an edge 170 opposite the edge hinge joint 166 and simply flipped into position over the normal viewing window 148 in the window aperture 113 for magnifying the display D of the electronic device E, or turned back to access the normal viewing window 148.
The edge hinge joint 166 coupling the flexible sheet magnifier 112 is optionally removably hinged along one side of the lid 104. For example, the lid 104 is formed with an open tubular “keyhole” slot 172 along one sidewall 122, the slot 172 having a lengthwise opening 174 adjacent to the window aperture 113. The edge 168 of the flexible sheet magnifier 112 is formed with a substantially cylindrical key-shaped insert 176 structured to mate with and be retained by the female slot 172. The flexible sheet magnifier 112 is operable like a page or cover of a book, i.e., it is grasped along the edge 170 opposite the edge hinge joint 166 and simply flipped into position over the normal viewing window 148 in the window aperture 113 for magnifying the display D of the electronic device E, or turned back to access the normal viewing window 148.
The sliding magnifier 112 is mounted on the lid 104 by engaging one end of the key-shaped insert 176 with one end of the keyhole slot 172 and sliding the insert 176 along the keyhole slot 172 to a position beside the window aperture 113 in the lid 104. Optionally, the sliding magnifier 112 is removable from the lid 104 by continuous sliding of the insert 176 along the keyhole slot 172 until the insert 176 disengages from the keyhole slot 172. The sliding magnifier 112 is replaceable on the lid 104 by re-engaging the insert 176 with the mating keyhole slot 172 and sliding the magnifier 112 into position beside the window aperture 113.
When the opening 174 in the tubular keyhole slot 172 is sufficiently open, and the edge 168 of the flexible sheet magnifier 112 is sufficiently thin as compared with the opening 174, the tubular keyhole slot 172 operates in combination with the cylindrical key-shaped insert 176 to form an alternative edge hinge joint 166 to the example illustrated in
Thus, according to one embodiment, the clamping mechanism 187 is formed by the window sash 189 being secured to the window aperture lip portion 186 by the securing mechanism 197. For example, the peripheral sealing lip 184 of the membrane-type window 148 is clamped between the frame contact surface 196 and the opposing rigid lip portion 186 of the window aperture 113 by the clamping mechanism 187 when the fasteners 200 are secured to the lip portion 186 of the window aperture 113 around the window sash 189. The central thin resiliently pliable window panel 182 within the peripheral sealing lip 184 is thus secured across the window aperture 113 in the lid floor 114.
According to different alternative embodiments of the securing mechanism 197, the window sash 189 is secured to the floor 114 of the lid 104 using another fastening mechanism, such as flexible clips, or another suitable mechanism capable of securing the window sash 189 against the lid floor 114, whereby the fastener apertures 198 and fasteners 200 are eliminated.
Although illustrated by example and without limitation as being positioned inside the lid 104, the membrane-type window 148 and the substantially water-resistant circumferential sealing mechanism 180 are alternatively positioned against the substantially rigid lip portion 186 of the window aperture 113 on a substantially planar outside upper surface 201 of the lid floor 114.
When the optional circumferential barriers 202, 204 are present, the peripheral sealing lip 184 is optionally formed having a substantially planar surface that is a continuation of the interior window panel 182 such that the peripheral sealing lip 184 does not have any increased thickness. Rather, the circumferential barriers 202, 204 optionally operate either to dig into the relatively soft and pliable material of the peripheral sealing lip 184, or to extrude the peripheral sealing lip 184, thereby eliminating any need for the increased thickness described herein.
The combination of the peripheral sealing lip 218 and circumferential ridge 219 thus operate as the clamping mechanism 187 by clamping the peripheral sealing lip 218 of the membrane-type window 148 tightly against circumferential ridge 219.
When the circumferential sealing mechanism 180 for the membrane-type window 148 is configured as the circumferential ridge 219 and slot 220, an optional expanding mechanism 221 for expanding peripheral sealing lip 218 of the membrane-type window 148 so that the slot 220 engages the circumferential ridge 219. For example, the flexible window panel 182 is optionally formed with one or more lengthwise stiffeners 222 (also shown in
The optional lengthwise and crosswise stiffeners 222, 223 of the optional expanding mechanism 221 are positioned to avoid interference with viewing and operating the electronic device E. For example, the lengthwise and crosswise stiffeners 222, 223 are spaced away from the center of the flexible window panel 182 in close proximity to the peripheral sealing lip 218 so as to be positioned outside the footprint of the device display D and the device control key pad P. When one of the optional crosswise stiffeners 223 is positioned near the center of the flexible window panel 182, its position is optionally adjusted to lie in a nonfunctional area of the electronic device E, such as between the device display D and the device control key pad P, whereby the optional crosswise stiffeners 223 is adapted to cooperate with the electronic device E.
According to another embodiment, the optional expanding mechanism 221 is configured as an optional hoop stiffener 224 formed as a thin and narrow hoop of a resiliently flexible spring material, such as of one of the spring materials discussed herein, or another suitable spring material. The hoop stiffener 224 is, for example, formed as a continuous loop having the same general shape as the peripheral sealing lip 218 and being only slightly smaller in length and width than the circumferential slot 220. The optional hoop stiffener 224 is, for example, coupled to the flexible window panel 182 of the membrane-type window 148 by being embedded or molded into the surface of the flexible window panel 182 in approximately the position occupied by the lengthwise and crosswise stiffeners 222, 223. Alternatively, the optional hoop stiffener 224 is coupled to the flexible window panel 182 of the membrane-type window 148 by adhesion onto the surface of the flexible window panel 182 using, for example, a suitable bonding agent such as RTV adhesive or another suitable adhesive. The optional hoop stiffener 224 is thereby spaced away from the center of the flexible window panel 182 in close proximity to the peripheral sealing lip 218 so as to be positioned outside the footprint of the device display D and the device control key pad P. Alternatively, the optional hoop stiffener 224 is coupled to the peripheral sealing lip 218, for example, by being molded into the surface of the peripheral sealing lip 218. The hoop stiffener 224 is, for example, positioned immediately inboard of the circumferential slot 220 to exert maximum expansive pressure on the sealing lip 218 to push the slot 220 into sealing contact with the circumferential ridge 219 on the inner periphery of the window aperture 113. The hoop stiffener 224 is optional positioned in the plane of the slot 220 so that moment or torque that could warp the peripheral sealing lip 218 is avoided.
The hoop stiffener 224 of the optional expanding mechanism 221 is sufficiently flexible to be temporarily bent or flexed without buckling during entry of the window 148 into the window aperture 113. Additionally, the hoop stiffener 224 is sufficiently resilient to straighten after entry of the window 148 into the window aperture 113 and to thereafter expand the circumferential slot 220 of the peripheral sealing lip 218 into sealing contact with the circumferential ridge 219 on the inner periphery of the window aperture 113.
The circumferential sealing mechanism 180 optionally includes one or both of the lengthwise and crosswise stiffeners 222, 223. Alternatively, the circumferential sealing mechanism 180 optionally includes the hoop stiffener 224. Optionally, the circumferential sealing mechanism 180 optionally includes the hoop stiffener 224 in combination with one or both of the lengthwise and crosswise stiffeners 222, 223.
When formed with the circumferential slot 234 and grooves 236, the circumferential sealing mechanism 180 optionally includes one or both of the lengthwise and crosswise stiffeners 222, 223. Alternatively, the circumferential sealing mechanism 180 optionally includes the hoop stiffener 224. Optionally, the circumferential sealing mechanism 180 optionally includes the hoop stiffener 224 in combination with one or both of the lengthwise and crosswise stiffeners 222, 223.
As shown, the dry box 100 may not be completely weather tight, since the lid 104 may not completely seal the opening 240 in the end of the container 102. However, the dry box 100 is expected to be reasonably water-resistant when the sealing mechanism 105 is utilized between respective peripheral lip portions 244, 246 formed around the opening 240 and the lid 104.
Other conventional catch mechanisms are also contemplated and can be substituted without deviating from the scope and intent of the present invention. For example, device manufacturers provide many portable electronic devices E with the structure S a pair of notches N formed along the opposing device sides ES1, ES2 for securing the devices E in a holding bracket. As an alternative to wedging into a slot structure S, the tabs 310, 312 on the side wings 306, 308 fit into the notch structure N for attaching cover mechanism 300 to the portable electronic device E The tabs 310, 312 may also be slidably engaged with the notch structure N and slidable along the structure.
The window aperture 113 is positioned over the device display D with the magnifier 112 there over for enlarging the appearance of a display portion D. For example, the magnifier 112 magnifies the display D about 150 percent or more when the cover 300 is positioned about arm's length from the user's face, but may be any desired magnification which makes information appearing on the display D appear larger, and therefore, easier to view. The magnifier 112 is any of the different magnification mechanisms described herein, including the optically transparent conventional convex lens, and the optically transparent Fresnel lens, or another magnification mechanism capable of enlarging the appearance of a display portion D by a desired percentage which makes information appearing on the display D appear larger, and therefore, easier to view.
The side wings 306, 308 of the cover mechanism 300 operate in combination with the tabs 310, 312 and the device side slot S or notches N to provide an offset mechanism 313 for offsetting the magnifier 112 at a selected distance from the display D that effectively focuses the magnifier 112 on the display D.
The cover mechanism 300 is formed with an overall length that ensures that, while the magnifier 112 covers the device display D, the bottom edge 314 is sized to clear the device control key pad P so the user can access and manipulate the buttons.
The magnifier 112 and the cover mechanism 300 may be coupled using any mechanism whereby the magnifier 112 can be secured to the cover 300. This includes snapping, clamping, fastening, sliding, gluing, adhering, or any other method for securing two components together.
Alternatively, the magnifier 112 is integral with the cover mechanism 300, both being formed of the optically transparent material of the magnifier 112. For example, the magnifier 112 and cover 300 are both formed of glass, acrylic, plastic, or polycarbonate, or anther optically transparent material capable of being formed into an optical magnification mechanism. The length of the side wings 306, 308 is selected for spacing the magnifier 112 an appropriate distance from the display D when installed onto the electronic device E. The thickness of the side wings 306, 308 is selected to provide sufficient resilient flexibility to spread over the opposing sides ES1, ES2 electronic device E and clamp the matching tabs 310, 312 into the slot S between the separable top and bottom covers Et, Eb.
According to one embodiment of the invention, the magnifier 112 is adhered to the top surface Ets of the electronic device E using a suitable adhesive. Alternatively, one or more flexible clips 324 formed either on the top surface Ets of the electronic device E, or as part of a separate band 326 that fits around the electronic device E. Alternatively, the band 326 is an elastic band that is attached to opposite sides of the magnifier 112. According to one embodiment of the invention, the magnifier 112 is formed with one or more flexible clips 328 that extend from the magnifier 112 and clip the magnifier 112 into a relief R frequently formed in the top surface Ets of the electronic device E and outlining the display D. Other conventional mechanisms for either permanently or temporarily coupling the magnifier 112 to the electronic device E over the display D are similarly contemplated, including snapping, clamping, fastening, sliding, gluing, adhering, or any other method for securing two components together, and can be substituted without deviating from the scope and intent of the present invention. By example and without limitation, an adhesion bond 330 is formed between the magnifier 112 and the top surface Ets of the electronic device E using, for example, an RTV adhesive of the type discussed herein.
According to one embodiment of the invention, the Fresnel lens magnifier 112 formed of the thin resiliently pliable membrane that operates magnify the appearance of both the display D of the electronic device E. For example, the Fresnel lens magnifier 112 is a sheet of flexible magnifying plastic of a type that is discussed herein. As such, the plastic material of the Fresnel lens magnifier 112 is cut or otherwise formed to fit into the relief R in the top surface Ets of the electronic device E. When pressed against the surface of the device display D and air bubbles are squeeze out of the interface, the pliable membrane Fresnel lens magnifier 112 effectively adheres to the display D without either the flexible tabs 328 or an adhesive. Installation of the magnifier 112 is thus greatly simplified.
The permanently bendable rod 334 is coupled to the magnifier 112, by example and without limitation, by adhesive bonding into an aperture 336 (shown in phantom) formed in the material of the magnifier 112, as shown. Other means for coupling the permanently bendable rod 334 to the magnifier 112 are also contemplated and can be substituted without deviating from the scope and intent of the present invention. For example, the permanently bendable rod 334 is alternatively bonded, soldered, welded, clamped, adhesively bonded or otherwise mechanically coupled to the magnifier 112 by another known coupling method or device.
The bracket 332 is optionally coupled to the device E by a pair of side wings snapping over the opposing sides ES1, ES2 of the device E and tabs 310, 312 wedging into the side slot structure S or into the notch structure N, as discussed in
According to one embodiment of the bracket 332 of the invention, the bracket 332 includes a pair of “C” or “U”-shaped channels 338 slightly deeper than a thickness of the target device E and coupled together by a bridge 340 that spaces the channels 338 slightly wider than the width of the device E. Thus sized and spaced, the channels 338 slide over the body of the device E and engage with a sufficiently close fit as to be retained by the device E, yet loosely enough to be easily disengaged. Thus, the magnifier 112 is easily temporarily installed on the electronic device E and is easily arranged over the display D or displaced from its magnifying position.
The rod is optionally bent to displace the magnifier 112 from its position for magnifying the display D, such as when the user does not require or desire to view the magnified appearance. Accordingly, the rod 334 is bent upwardly away from the display D in the direction indicated by the arrow “Z,” whereby the magnifier 112 is bendably displaced from its magnifying position. Alternatively, the rod 334 is twisted sideways relative to the display D in the direction indicated by the arrow “Y,” whereby the magnifier 112 is also displaced from its magnifying position.
The magnifier 112 is coupled to a stiff metal or plastic shaft 344 having a resilient locking head 346. For example, the magnifier 112 is coupled to a head 348 (shown in phantom) of the shaft 344 opposite the locking head 346 by being adhered, soldered, welded, clamped, adhesively bonded or otherwise mechanically coupled by another known coupling method or device. The locking head 346 is structured to engage a mating retainer lock 350 that is coupled to the top surface Ets of the electronic device E in a position that permits the magnifier 112 to be positioned over the display D of the device E for viewing the display D having a magnified appearance by a joint 351 between a base 353 of the retainer lock 350 and the device-top surface Ets, whereby the retainer lock 350 is adhered, soldered, welded, clamped, adhesively bonded or otherwise mechanically coupled by another known coupling method or device to the top surface Ets of the electronic device E. The shaft 344 is sized to cooperate with the retainer lock 350 offset the magnifier 112 at a selected distance from the display D that effectively focuses the magnifier 112 on the display D.
The resilient locking head 346 is formed, by example and without limitation, having a pair of resiliently flexible spaced-apart teeth 352 structured to compress for entering a mating aperture 354 in the mating retainer lock 350 with a light hand-pushing pressure, and similarly to compress for disengaging from the aperture 354. The magnifier 112 is thus detachable from the electronic device E. Therefore, when multiple mating retainer lock 350 are acquired and coupled to surfaces of other devices, including other electronic devices, the magnifier 112 is useable for viewing a magnified appearance of any device display or other object desired by the user.
The shaft 344 optionally includes a stabilizing mechanism 356 for stabilizing the magnifier 112 relative to the device E and display D. By example and without limitation, the stabilizing mechanism 356 is provided, by example and without limitation, by a collar 358 fixed on the shaft 344 adjacent to the locking head 346 at a distance that results in engagement with a top surface 360 of the retainer lock 350 when the locking head 346 is engaged with the retainer lock 350. Other stabilizing mechanisms are also contemplated and can be substituted without deviating from the scope and intent of the present invention.
The locking head 346 is substantially conical with the shaft 344 being substantially cylindrical such that the locking head 346 and shaft 344 are rotatable relative to the retainer lock 350. Accordingly, the locking head 346 and shaft 344 are rotatable about the longitudinal axis of the shaft 344 over the display D in the directions indicated by the arrows “+X” and “−X,” whereby the magnifier 112 is rotatably placed into its magnifying position. Also, the locking head 346 and shaft 344 are rotatable away from the display D in the directions indicated by the arrows “+X” and “−X,” whereby the magnifier 112 is rotatably displaced from its magnifying position.
The locking head 346 and retainer lock 350 are optionally formed with one or more mating flats 362, 364 that, when engaged, fix the relative rotational orientation of the locking head 346 to the retainer lock 350, whereby the magnifier 112 is rotationally fixed over the display D in its magnifying position.
Optionally, when engaged, the mating flats 362, 364 fix the magnifier 112 rotationally displaced from its magnifying position. The mating flats 362, 364 are optionally structured by a well-known method of relative sizing to permit a user to rotate the locking head 346 relative to the retainer lock 350 for rotatably placing the magnifier 112 into or displacing it from its magnifying position over the display D. According to one embodiment, a portion (indicated at 362) of the shaft 344 adjacent to the locking head 346 is square, rectangular, hexagonal, octagonal or another multi-sided shape and is matched by a cooperating shape in the mating aperture 354, whereby multiple mating flats 362, 364 are provided between the locking head 346 and the retainer lock 350. Thus, a light rotational force is required to rotate the locking head 346 relative to the mating aperture 354, whereby the magnifier 112 is fixed in a different rotational orientation with the display D.
A slot 366 is formed in the wall surface of the retainer lock 350 and cutting into the part spherical interior cavity of the mating aperture 354. The slot 366 permits the mating aperture 354 to spread to admit the ball locking head 346 through a mouth or opening (also indicated at 354) into the mating aperture 354 that is smaller than the interior cavity of the mating aperture 354 and, consequently, smaller than the ball locking head 346. The retainer lock 350 is manufactured of a resiliently elastic material, such as plastic, whereby the slot 366 closes and the part spherical interior cavity of the mating aperture 354 returns substantially to its pre-engagement condition after the ball locking head 346 is entered into and engaged with the mating retainer lock 350. Thus, the ball locking head 346 is engaged with the retainer lock 350 using a light hand-pushing pressure. Similarly, the slot 366 and for disengaging the ball locking head 346 from the aperture 354.
The collar 358 of the stabilizing mechanism 356 is fixed on the shaft 344 adjacent to the locking head 346 at a distance that results in engagement with the top surface 360 of the retainer lock 350 when the locking head 346 is engaged with the retainer lock 350. Other stabilizing mechanisms are also contemplated and can be substituted without deviating from the scope and intent of the present invention.
The collar 358 and the shaft 344 between the collar 358 and the ball locking head 346 are both formed with flats 362 that remove portions on opposing sides of the collar 358 and shaft 344. The remaining collar and shaft material is thus formed with the flats 362 that are sized to fit into the slot 366 in the retainer lock 350. The flats 362 permit the shaft 344 to enter into the slot 366 such that, when the locking head 346 is rotated within the retainer lock 350, the shaft 344 is swiveled by an angle “a” in the away from the display D in the direction indicated by the arrow “Z,” whereby the magnifier 112 is displaced by swiveling from its magnifying position. According to one embodiment of the invention, the slot 366 is deep enough to permit the shaft 344 to swivel to a swivel angle α of 90 degrees or more, whereby the magnifier 112 is swiveled completely clear of the device display D. Alternatively, the slot 366 is relatively shallow, whereby the shaft 366 is restricted to a swivel angle α of about 30 to 45 degrees. According to one embodiment, the collar 358 collides with and operates against a surface of the outer shell or exterior surface (indicated at 350) of the retainer lock 350 between the slot 366 and the retainer lock base 353, such that the shaft 344 does not encounter the extreme end (not visible) of the slot 366 distal from the mouth or opening (indicated at 354) into the mating aperture 354. According to one embodiment, the slot 366 and shaft 344 are relatively sized to fit snugly together such that a friction force is generated between them during the swiveling operation, whereby a light hand-pushing pressure is used to swivel the shaft 344 through the slot 366. Alternatively, the slot 366 and shaft 344 are relatively sized to fit loosely together such that little or no effort is required to swivel the shaft 344 through the slot 366. Accordingly, the slight flick of a finger is used to swivel the shaft 344 through the slot 366, whereby the magnifier 112 is swiveled into its magnifying position or swiveled out of its magnifying position.
Optionally, when engaged, the mating flats 362, 364 fix the magnifier 112 rotationally displaced from its magnifying position. The mating flats 362, 364 are optionally structured by a well-known method of relative sizing to permit a user to rotate the locking head 346 relative to the retainer lock 350 for rotatably placing the magnifier 112 into or displacing it from its magnifying position over the display D. According to one embodiment, a portion (indicated at 362) of the shaft 344 adjacent to the locking head 346 is square, rectangular, hexagonal, octagonal or another multi-sided shape and is matched by a cooperating shape in the mouth or opening of the mating aperture 354, whereby multiple mating flats 362, 364 are provided between the locking head 346 and the retainer lock 350. Thus, a light rotational force is required to rotate the ball locking head 346 relative to the mating aperture 354, even when the ball locking head 346 is sized smaller than the part spherical interior cavity of the mating aperture 354 such that the ball locking head 346 is otherwise easily rotatable within the mating aperture 354. Thus, the magnifier 112 is fixed in a different rotational orientation with the display D.
While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. For example, the different mechanism disclosed herein are optionally combined in different ways to achieve similar results in different embodiments of the invention. In one specific example, the embodiment of the invention illustrated in
Full Window With Integral Double Seal
As discussed above herein, the optically transparent normal-viewing window 148 (shown first in
However, the thin and flexible character of this embodiment of the optically transparent window 148 leaves it sensitive to exposure to rough treatment and the every day risks of the world in general. The circumferential window sealing mechanism 180 of the type shown in
The protective case for an electronic device as taught Richardson in U.S. Pat. No. 6,646,864 is another dry storage box that has a touch screen. Richardson's box includes a thin plastic membrane in one surface that is adapted to the specific contour and profile of the electronic device and allows tactile inputs to the device's touch screen interface while the device is secured inside the case.
Experience with the Richardson protective case indicates that one shortcoming of such protective boxes is severe and permanent damage that the thin plastic membrane suffers from prolonged exposure to sunlight, which is likely to occur when the protective case is used for its intended purpose to protect the electronic device from exposure to the outdoor elements. The thin plastic membrane suffers under prolonged exposure to the heat of the sun when the device is mounted on a boat, motorcycle, all terrain vehicle (ATV) and used during prolonged outdoor activities. The thin plastic membrane can heat up enough to cause irreparable damage even when mounted inside a car or truck, especially if it is mounted in the common location on the vehicle dash just below the windscreen and in direct sunlight. The prolonged exposure to the sun's UV (ultraviolet) radiation may also be a detrimental factor. The plastic membrane may become stiff and unresponsive to tactile inputs, thereby rendering the case ineffective for its intended purpose. The membrane may become sufficiently dry with time that it could crack, thereby losing its ability to seal the electronic device within from rain and damp. With time, too, optical performance of the membrane may suffer leaving the user unable to effectively view the protected device.
Replacement of the membrane is an option that is not always viable. For example, the user may not have a spare membrane, and running to run to the store or waiting for a replacement by mail may not be feasible.
Accordingly, the present invention provides a novel alternative optically transparent one-piece dry box window for the protective dry box 100, the novel one-piece window having a virtually unbreachable seal and integrates the substantially water-resistant circumferential door seal mechanism 105 between respective peripheral lip portions 106, 108 formed around respective openings into the respective container 102 and lid 104.
The circumferential window sealing mechanism 402 is a window gasket formed, by example and without limitation, as a continuous peripheral sealing lip 406 having a relatively increased thickness as compared with the interior thin resiliently pliable window panel 182 that it surrounds. For example, the continuous peripheral sealing lip 406 is formed as an enlarged lump or raised bump or swelling of the membrane material of which the one-piece dry box window 400 is formed.
The peripheral sealing lip 406 surrounds and is integral with the central flexible window panel 182 of the one-piece dry box window 400, and by example and without limitation, extends on one side (hereinafter “above”) of the plane of the central flexible window panel 182. The flexible window panel 182 is slightly smaller in dimension than the window aperture 113 in the lid 104 with the peripheral sealing lip 406 interfacing with a circumferential lip 408 (shown in subsequent Figures) formed on the inner periphery of the window aperture 113. A contoured fillet 410 of material joins the peripheral sealing lip 406 to the flexible window panel 182 and simultaneously stiffens the peripheral sealing lip 406.
The peripheral sealing lip 406 surrounding the flexible window panel 182 is slightly larger than the window aperture 113 and is formed with a circumferential groove or slot 412 that is sized to engage the ridge portion 408 of the inner periphery of the window aperture 113 under slight compression, with the relatively soft and pliable peripheral sealing lip 406 spreading slightly to receive the rigid inner peripheral ridge 408 of the window aperture 113, whereby the circumferential slot 412 of the peripheral sealing lip 406 forms a substantially water-resistant sealing relationship with the ridge portion 408 of the window aperture 113. According to one embodiment of the present invention, the circumferential groove or slot 412 is formed, by example and without limitation, the same side of the central flexible window panel 182 with the bulk of the peripheral sealing lip 406. In other words, the circumferential slot 412 is formed above the plane of the central flexible window panel 182.
The circumferential slot 412 is optionally formed in the plane of the central flexible window panel 182 when the peripheral sealing lip 406 is formed in the plane of the central flexible window panel 182, as illustrated herein for the window 148.
An integral continuous flexible contoured skirt 414 completely surrounds the integral circumferential window sealing mechanism 402 and couples the integral peripheral lip portion 404 thereto.
The ridge portion 408 of the window aperture 113 is formed with an inner contact surface 416 on an inside surface 418 of the lid floor 114 and an the outer contact surface 420 spaced away on the opposite outer surface 201 of the lid floor 114. One or both of the inner and outer contact surfaces 416, 420 are optionally substantially planar in form. The circumferential groove or slot 412 of the integral circumferential window sealing mechanism 402 fits over and grips both the inner and outer contact surfaces 416, 420 of the lid floor 114. Thus, the integral circumferential window sealing mechanism 402 forms a substantially water resistant circumferential seal 422 with the lid floor 114.
As discussed herein, the container 102 and lid 104 are both constructed of light weight, substantially rigid, water-resistant material. The substantially water-resistant circumferential seal 105 along respective peripheral lip portions 106, 108 around the openings of the respective container 102 and lid 104 is formed by compressing the resiliently deformable gasket 126 within the channel 124 in the lid 104. The cooperating tongue 123 in the container 102 contacts and partially deforms the gasket 126 when the lid 104 is rotated on the hinge 116 and closed relative to the container 102 with the latch mechanism 110 engaged.
According to one embodiment of the present invention, the integral peripheral lip portion 404 of the one-piece dry box window 400 forms the substantially water-resistant circumferential seal mechanism 105 between respective peripheral lip portions 106, 108 formed of the respective container 102 and lid 104. The integral peripheral lip portion 404 forms a gasket of the resiliently deformable material of the one-piece dry box window 400. The integral peripheral lip portion 404 is sized to fit into the channel 124 and cooperate with the tongue 123. Accordingly, the integral lip portion 404 is positioned at least partially within the channel 124 so that the tongue 123 contacts and at least partially deforms the lip portion 404 when the lid 104 is rotated on the hinge 116 and closed relative to the container 102 with the latch mechanism 110 engaged. The integral peripheral lip portion 404 of the one-piece dry box window 400 thus cooperates with the channel 124 and tongue 123 to form the substantially water-resistant circumferential seal 105.
The one-piece dry box window 400 further includes the integral contoured skirt 414 that completely surrounds the integral circumferential window sealing mechanism 402 of the integral optically transparent interior window panel 182 and extends to integrate the integral peripheral lip portion 404 with the entirety of the one-piece dry box window 400. The skirt 414 is contoured to substantially match a contour of the inside surface 418 of the box lid 104. Additionally, the skirt 414 is integrally formed with the peripheral lip portion 404 that is structured to form the substantially water-resistant circumferential seal mechanism 105 between respective peripheral lip portions 106, 108 formed around respective openings into the respective container 102 and lid 104.
A bond 424, such as an adhesive bond, is optionally formed between the contoured skirt 414 and the inside surface 418 of the box lid 104. However, the circumferential window seal 422 at the sealing mechanism 402 and insertion of peripheral lip portion 404 within the channel 124 is believed sufficient to retain the one-piece dry box window 400 relative to the box lid 104, whereby the bond 424 is redundant.
The circumferential slot 412 and keyway 432 are respectively sized to engage the main body 430 and the circumferential key teeth or key wall 428 of the ridge portion 408 of the inner periphery of the window aperture 113 under slight compression, with the relatively soft and pliable peripheral sealing lip 406 of the sealing mechanism 402 spreading to receive both the main body 430 and the circumferential key teeth or key wall 428 of the rigid inner peripheral ridge 408.
While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
In another example, the entire window sealing mechanism 402 is inverted, without departing from the spirit and scope of the invention. In other words, the peripheral sealing lip 406 of the sealing mechanism 402 is formed on an inside surface 434 of the one-piece dry box window 400 with the window panel 182 outside. In yet another example, the circumferential slot 412 and keyway 432 are reversed with the circumferential key teeth or key wall 428 of the rigid inner peripheral ridge 408 extending inside the box lid 104, and the circumferential keyway 432 of the slot 412 turned downward to match.
Also illustrated is the integral continuous peripheral lip portion 404 formed as an integral sheet or flap of the water-resistant and resiliently pliable material that is shaped to lay between the substantially parallel peripheral lip portions 106, 108 formed around respective openings into the respective container 102 and lid 104 for forming the substantially water-resistant circumferential seal 105. The continuous peripheral sheet or flap lip portion 404 is, by example and without limitation, molded integrally with the entire one-piece dry box window 400. The one-piece dry box window 400 is formed with the continuous peripheral flap lip portion 404 spread out away from the contoured skirt 414 and substantially parallel with the window panel 182 such that the continuous peripheral flap 404 in a relaxed state naturally folds over the lid's peripheral lip portion 108. Additionally, the bond 424 between the contoured skirt 414 and the inside surface 418 of the box lid 104 is optionally extended between the continuous peripheral flap 404 and the lid's peripheral lip portion 108.
One or both of the respective peripheral lip portions 106, 108 around the openings of the respective container 102 and lid 104 is formed with one or more circumferential barriers 435 shown here as a ridge projected from each of the respective peripheral lip portions 106, 108 into the gap therebetween, which is substantially filled with the continuous peripheral flap 404 portion of the one-piece dry box window 400.
When present, the optional circumferential ridge-type barriers 435 along respective peripheral lip portions 106, 108 dig into and partially deform the relatively soft and pliable peripheral sealing lip flap 404 when the lid 104 is rotated on the hinge 116 and closed relative to the container 102 with the latch mechanism 110 engaged. The optional circumferential ridge-type barriers 435 thus increase the quality of the sealing mechanism 105 by adding additional barriers against moisture intrusion.
By example and without limitation, the optical magnifier 112 is any of the different magnification mechanisms described herein, including the optically transparent conventional convex lens, and the optically transparent Fresnel lens, or another magnification mechanism capable of enlarging the appearance of a display portion D by a desired percentage which makes information appearing on the display D appear larger when viewed.
By example and without limitation, a bond joint 440 is optionally formed between the peripheral sealing lip 406 of the circumferential window sealing mechanism 402 and the peripheral edge portion 438 of the optical magnifier 112 using a suitable adhesive such as a conventional room RTV or another suitable adhesive. Alternatively, the bond joint 440 is optionally formed by ultrasonically welding the magnifier 112 to the lid 104 to the peripheral sealing lip 406 of the circumferential window sealing mechanism 402.
The continuous peripheral sealing lip 406 of the circumferential window sealing mechanism 402 is optionally molded onto the peripheral edge portion 438 of the optical magnifier 112 during an injection molding process in which the one-piece dry box window 400 of the present invention is formed.
Optionally, the optical magnifier 112 is integrally formed with the entire one-piece dry box window 400 of the present invention during a single molding or other forming operation. Accordingly, the outer peripheral edge portion 438 of the optical magnifier 112 is integral with the continuous peripheral sealing lip 406 of the circumferential window sealing mechanism 402, and the inner circumferential groove or slot 436 is eliminated.
While the preferred and additional alternative embodiments of the invention have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. Therefore, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention. Accordingly, the inventor makes the following claims.
