Preferred and alternative examples of the present invention are described in detail below with reference to the following drawings:
Referring to
In the illustrated embodiment, the first base portion 14a pivotably secures to the second base portion 14b by both pivotably securing to a joining portion 20. In the illustrated embodiment, the base portion 14a pivotably secures to the joining portion 20 by means of hinges 22a and the base portion 14b pivotably secures to the joining portion 20 by means of hinges 22b. The base portions 14a, 14b may be pivotably mounted to the joining portion 20 such that they are pivotable about an axis of rotation parallel to the horizontal direction 12b. As is apparent in
In some embodiments, the base portions 14a, 14b and joining portion 20 are not pivotable with respect to one another and may include a single rigid member. In some embodiments, the mat 16 is removable from the base portions 14a, 14b. In others, the mat 16 is omitted or is secured to the base portions 14a, 14b (such as in separate pieces secured to the base portions) by means of glue or some other fastening mechanism.
In typical use, the infant will be positioned on the mat 16 aligned with the longitudinal direction 12a, i.e. the infant's legs and spine aligned with the longitudinal direction 12a. A barrier 24 is mounted to the base portions 14a, 14b such that the arms and torso of the infant are positioned on one side of the barrier 24 and the legs and bottom of the infant positioned on the opposite side of the barrier 24, thereby limiting the infant's hands to contact a diaper, feces, or the infant's soiled bottom. When finished, the barrier 24 may then be removed and the infant removed from the mat 16. The barrier 24 and base portions 14a, 14b may be formed of a rigid plastic such as ABS (Acrylonitrile butadiene styrene) plastic.
In the illustrated embodiment, the barrier 24 extends in the horizontal and vertical directions 12b, 12c such that the vertical extent of the barrier 24 is sufficiently high to inhibit access of the infant to soiled areas and items. In the illustrated embodiment, the barrier 24 includes arms 26a, 26b that connect to the joining portion 20. A lower edge of the barrier 24 and inner surfaces of the arms 26a, 26b define an archway for receiving the torso of the infant placed on the mat. In some embodiments, an insert 28 may secure to the lower edge and/or arms 26a, 26b in order to reduce the vertical and/or horizontal extent of an opening between the barrier 24 and the mat 16 and to provide cushioning to avoid harm to the infant. The insert 28 may be formed of a padding material such as EVA foam, memory foam, or other type of foam. The insert 28 may include foam having a synthetic outer liner that prevents bacteria or other microorganisms from entering the foam. The insert 28 may secure to the barrier 24 by any removable fastening means known in the art, such as clips, snaps, hook-and-loop fastening elements, or the like. In the illustrated embodiment, the insert 28 inserts within a slot 30 defined by the barrier.

Each shell portion 50 may define an arcuate lower edge 52 that is offset from a mating plane of the shell portions 50 when fastened to one another. In this manner, the insert 28 may be positioned between the shell portions 50 and extend through the lower edges 52 of the shell portions 50 in order to engage the torso of an infant resting on the mat 16. In the illustrated embodiment, the shell portions define ledges 54 protruding inwardly from the arms 26, 26b. The insert 28 includes corresponding shoulders 56 that rest on the ledges 54 in order to support the insert 28 and maintain its position. The insert 28 may have a thickness such that when fastened between the shell portions 50, the shell portions 50 exert pressure thereon and resist movement of the insert 28. In some embodiments, the insert 28 is able to move upwardly between the shell portions 50 subject only to friction. In some embodiments, one or more structures on the shell portions 50 engage an upper edge of the insert 28 and prevent upward movement. In the illustrated embodiment, the insert 28 includes rows of perforations that facilitate compression of the insert 28 thereby increasing comfort for the infant.
One or more of the shell portions 50 may define one or more structures for mounting an actuator for the latching mechanisms 34a, 34b and couplers for transferring force between the actuator and the latching mechanisms 34a, 34b.
In the illustrated embodiment, one or both of the shell portions 50 defines an aperture 58 that slidably receives an actuator implemented as a button 60. The button 60 exerts force on couplers, embodied as push rods 62 in the illustrated embodiment, for disengaging the latching mechanisms 34a, 34b. The push rods 62 may pass through channels 64 formed on or secured to at least one of the shell portions 50. This increases the amount of displacement on one end of the push rod 62 that will be transferred to a second end of the push rod 64 by reducing or preventing buckling of the push rods 62. In some embodiments, the channels 64 are formed on both shell portions 50 such that both function to contain and prevent buckling of the push rods 62. The push rods 62 may be made of a rigid plastic, metal, or other material that is able to transfer force. The channels 64 may define a path such that the push rods 62 must deform when pushed through the channels 64. Accordingly, the push rods 62 are preferably sufficiently compliant to permit this deformation.
Referring to
A spring 70 or other biasing member may be positioned between the buttons or between a single button and an opposing surface on an opposing shell portion 50. This urges the buttons 60 outwardly in the absence of an external force. As discussed below, a restoring force exerted at the latching mechanisms 34a, 34b or by a separate biasing member may urge the wedges 66 inwardly when the ramps 68 are not exerting an outward force on the wedges 66.
A button 60 may include one or more pins 72 that engage corresponding holes 74 in the other button 60 or an opposing shell portion 50. In the illustrated embodiment, each button 60 includes both pins 72 and holes 74 for engaging corresponding holes 74 and pins 72 in an opposite button 60. This facilitates smooth sliding of the buttons 60 relative to one another and reduced binding with respect to one another or with respect to the shell portions 50.
The hook arms 86 define apertures 90 for rotatably mounting to the pivot pin 84. As is apparent in
The slider box 80 further includes release pins 100 positioned on either side of the hook arms 86a, 86b. The slider box 80 engages one of the push rods 62. When the slider box 80 is pushed downwardly by the push rod 62, the release pins 100 engage the hook arms 86a, 86b and urge the hook arms 86a, 86b inwardly in order to disengage the hooks 88 from the receptacle 32a, 32b.
In the illustrated embodiment, the slider box 80 is assembled in two pieces 80a, 80b that may be identical to one another. Each piece 80a, 80b includes a vertical member defining one of the slot 82s and having one of the pins 100 extending outwardly therefrom. On an opposite side of the slot 82 from the pin 100, the vertical member 102 is an aperture 104 for receiving a fastener 106 that secures to the pin 100 of the other piece 80a, 80b. The securement of each pin 100 of each piece 80a, 80b to the aperture 104 of the other piece 80a, 80b may be sufficient to secure the pieces 80a, 80b to one another.
In the illustrated embodiment, each piece 80a, 80b defines a portion of a push rod seat 108 that extends outwardly from the vertical member 102 along the longitudinal direction 12a. The push rod seats 108 of the pieces 80a, 80b are positioned adjacent one another and define a recess 110 for receiving a flange 112 on the push rod 62. Each push rod seat 108 may define an aperture 114 for receiving a fastener securing the flange 112 to the seat 108. The securement of the seats 108 to the push rod flange 112 may also serve to secure the pieces 80a, 80b to one another.
In the illustrated embodiment, each piece 80a, 80b further defines a bottom flange extending inwardly from the vertical member and positioned between the hook arms 86a, 86b. The bottom flanges 116 overlap one another and may define an angled surface 118 that engages one of the hook arms 86a, 86b. The bottom flanges 116 may therefore limit inward movement of the hook arms 86a, 86b. The vertical member 102 of each piece 80a, 80b may define a flange seat 120 that receives an end of the bottom flange 116 of the other piece 80a, 80b.
