DETAILED DESCRIPTION OF THE INVENTION

(10) Now referring to drawings in FIGS. 1-8, wherein similar components are identified by like reference numerals, there is seen in FIG. 1, the device 10, displayed in its deployed state, operatively supported upon the body of a user 12. As depicted the device 10 includes all of the preferred components required for operation the device 10 in any of the preferred modes described herein, and is adapted to support an infant upon the deployed platform.

(11) The device 10, per FIGS. 1 and 2 comprises a platform assembly 16 which is adapted for support upon the body of the user with a baby or infant supported on a flexible textile or fabric bed 28. A flexible member or waist strap 13 is engageable around the waist of a baby helps to support and maintain the baby 14 on the fabric bed 28 during use. Another flexible member or second waist strap 17 engages the body of the user and another flexible member in the form of a user neck strap 18, both combine to adapt the device 10 for a hanging support upon the body of a user during use such as in FIGS. 1-2.

(12) As shown in FIG. 3, the device 10 in the deployed configuration forms the platform assembly 16. This platform assembly 16 is comprised of a collapsible platform frame 16 which when the device is in the deployed configuration forms a temporarily rigid planar structure to support an engaged flexible fabric bed 28. This fabric bed 28 so supported is adapted to support the baby 14 during use. The device 10 in the deployed configuration of FIG. 3, is collapsible to the collapsed configuration of FIG. 6, as described herein making it easily stored and transported.

(13) In FIG. 4 is shown the platform frame 16 which has a preferred configuration and positioning of engaged hinges enabling it to be moved to the collapsed position of FIG. 6. The platform frame 16 includes four 90-degree rotatable hinges or first hinges 15, with one each positioned at each corner. The first hinges 15 are formed of pairs of first hinge components or male 90-degree hinges 20, and second hinge components or female 90-degree hinges 22, which are in operative rotational engagement to form each first hinge 15 which is configured to allow a 90 degree rotation of the first and second hinge components.

(14) Positioned at central positions on opposing sides of the platform frame 16, are two 180-degree hinges or secondary hinges 17. Each of these secondary hinges 17 are formed by first hinge components or male 180-degree hinges 24, and second hinge components or female 180-degree hinges 26, which are operatively engaged for rotation such as with hinge pins 30 or other means of engagement. The secondary hinges 17 rotate from the deployed configuration in FIG. 4, to a rotated position of FIG. 5, and are engaged to the platform frame 16 in a manner to preferably only rotate away from the fabric bed 28 situated above them such as shown in FIG. 3. This protects the device 10 from collapsing with an infant supported thereon. These secondary hinges 17 are configured for 180 degrees or relative rotation.

(15) Connecting each pair of first hinges 15 which are located at the corners of the platform frame 16, are primary members 32. One side of each first hinge 15 in each pair, is connected to one end of the primary members or members 32.

(16) Connecting each pair of first hinges 15 to the opposing centrally located secondary hinges 17, is a secondary member 34. Each secondary member 34 is connected to one of first or second hinge component on a first hinge 15, and to one of the first or second hinge components of a secondary hinge 17 on an opposite respective end. All connections of the primary members 32 and secondary members 34 to any of the first or secondary hinges may be accomplished with fasteners appropriate to the task. Such fasteners can be any from a group in including pins, screws, rods, adhesive, collared engagements, or other fasteners adapted to the task as would occur to those skilled in the art.

(17) The collapsible platform frame 16 is assembled such that both ends of each primary member 32 connect between two one end of opposing first hinges 15 located on two corners of the platform frame 16 at one end thereof.

(18) As shown in FIG. 4 a hinge pin 30 may be employed to constrain the first and secondary hinge components, and constrain each of the hinges to move in only one rotational direction of freedom with respect to each other. The fabric bed 28 may be sewn with sleeves otherwise engaged to the collapsible platform 16 such as is done with a cot or awning. For example, one or more platform fasteners 36 may be included on one or both sides of each of the first and secondary hinges for connection with the primary and secondary members 32 34, the fabric bed 28, and the straps 17 18.

(19) In operation in the deployed configuration of the device 10 as shown 1 and 2, the device 10 is adapted for support on the body of the user by looping the user neck strap 18 around the neck, and tightening the waist strap 17 about their hip or midriff. The user 12 then places the baby 14 on top of the fabric bed engaged on the collapsible platform 16 and secures the baby in place with the baby waist strap 13.

(20) In an alternative method of device 10 use, the user can first lay the baby 14 onto the collapsible platform frame assembly 16 and employ the baby waist strap 13 for safety before donning the device by placing the neck strap 18 over their head and tightening the waist strap 17 about their hip or midriff.

(21) As noted, the device 10 is moved from the deployed configuration using first and second folding stages enabled by the unique positioning of the hinges as displayed in FIGS. 5 and 6 respectively. By positioning the secondary hinges 17 in opposing positions in a center of the platform and first hinges 15 at all corners, the device 10 is easily moved to the collapsed configuration of FIG. 6 for easy transportation and storage.

(22) As shown in FIG. 5, the user 12 maneuvers the device 10 into its first folding stage by rotating the primary member 32 engaged on one end of the platform 16 to a position abutting and the primary member 32 connected between the first hinges 15 at the corners of the opposing side of the platform 16, by rotating both secondary hinges 17 concurrently and thereby folding the collapsible platform 16 in equal halves.

(23) Shown in FIG. 6, is the collapsed configuration of the device 10 achieved in the second folding stage of the device 10, wherein all four of the first hinges 15, are concurrently rotated, thereby collapsing both of the secondary hinges 17 and their engaged respective primary members 34 inward until they abut each other and the primary members 32, and where all of the primary members 32 and secondary members 34 have their respective axis running substantially parallel. By substantially parallel is meant that the axis of the primary members 32 and secondary members 34 are running along lines which are parallel or less than ten degrees off parallel, where the device 10 in the collapsed configuration of FIG. 6, is highly compact.

(24) Shown in FIGS. 7 and 8 display the preferred configuration of the first or male and second or female 180-degree hinge components shown as 24 26 respectively. As shown, a projection or male pin 48 and recess or female hollow socket 50, are adapted to rotationally engaged and accept a hinge pin 30 to maintain operative engagement and allow for smooth rotation between both parts.

(25) The first or male, and second or female 180-degree hinge components 24-26, preferably additionally include a rotation angle limiter formed by a mating stop pin 40 and stop slot 46 and stop 47. As shown, this stop slot 46 engages with the translating stop pin 40 during rotation of the two hinge components. A stop 47 is positioned within the stop slot 46 to cease translation of the stop pin 40 within the stop slot 46 during rotation of the two hinge components and thereby prevent the hinges from rotating beyond a relative angle of 180 degrees.

(26) As noted, preferably both of the secondary hinges 17 should be installed onto the platform frame 16, to fold only in a direction away from the planar fabric bed 28. This configuration prevents the weight of the baby 14 from collapsing the device 10 during use.

(27) The male and female components of the first hinges 15 located at the corners of the platform frame 16 should preferably include the same projection or male pin 48 and a recess or female hollow socket 50. Additionally they should preferably be configured with a mating stop pin 40 and stop slot 46 which has the stop 47 positioned to only allow the 90-degree hinges 15 to rotate up to a relative angle of 90 degrees. Of course the first hinges 15 are self restrained during use from over rotating by the engaged members and will work without inclusion of a rotation angle limiter, however inclusion of such a rotation limiting mechanism is preferred.

(28) Further, all first and secondary hinges in the device 10, may include a mating fastener 42 to accommodate the platform fasteners 36 and allow for permanent or temporary engagement of the fabric bed 28 and the rigidity of the collapsible platform frame 16.

(29) Although the orientation of the first hinges 15 and secondary hinges 17 in the first preferred mode of the device 10 prevents the collapsible platform 16 from folding under the weight of the baby 14, a second preferred mode of the device 10, could include a locking mechanism within the first hinges 15, and secondary hinges 17, or hinge pin 30 for additional safety. Such for example might include a spring loaded hinge pin 30 having a circumference edge on one end, which is adapted to engage both halves of the hinge unless disengaged by depressing the hinge pin 30.

(30) Alternately designed or currently available hinges with only a fixed range of bidirectional rotation of 90 or 180 degrees, which do or do not contain a locking mechanism can be employed instead of the first hinges 15, and secondary hinges 17, or hinge pin 30 described in the first preferred mode of the device 10 herein. However the configuration herein of the first hinges 15 and secondary hinges 17 and their rotation limitations and engagement to members is preferred.

(31) The cooperative engagement between mating fasteners such as with the fastening feature 42 and platform fasteners 36 on the hinges 15 and 17, and platform frame assembly 16 respectively can be any durable and permanent means of attachment including but not limited to those from a group including threadably engaged fasteners, rivets, over molding, bands, ties, buttons or pins.

(32) Additionally, each of the members 32 or 43 and its respective first hinge 15 or secondary hinge 17, can be formed from as a single part.

(33) Alternatively, the fabric bed 28 and the platform frame assembly 16 can contain temporary fasteners to allow for easy cleaning, stowage and transportation. Such might include rings through grommets, sleeves on the fabric bed 28 engageable with the frame, or other means for removable engagement.

(34) Additionally, it is preferred that all of the flexible members forming the straps 13 17 and 18 should be adapted with a tightener to adjust and maintain a secure connection to the user 12 and to the baby 14. Such tighteners can include one or a combination of tighteners from a group including cinches, slides, straps, buckles, buttons, clasps, ties, elastic and bands. All components of the first hinges 15 and secondary hinges 17 and hinge pins 30 and members 32 and 34 in the preferred mode of the device 10, should be made from a durable water resistant material including but not limited to: plastic, metal, wood or carbon fiber.

(35) As noted, any of the different configurations and components can be employed with any other configuration or component shown and described herein. Additionally, while the present invention has been described herein with reference to particular embodiments thereof and steps in the method of production, a latitude of modifications, various changes and substitutions are intended in the foregoing disclosures, it will be appreciated that in some instance some features, or configurations, or steps in formation of the invention could be employed without a corresponding use of other features without departing from the scope of the invention as set forth in the following claims. All such changes, alternations and modifications as would occur to those skilled in the art are considered to be within the scope of this invention as broadly defined in the appended claims.

(36) Further, the purpose of any abstract of this specification is to enable the U.S. Patent and Trademark Office, the public generally, and especially the scientists, engineers, and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. Any such abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting, as to the scope of the invention in any way.
