With reference now to the drawing figures, where like reference numbers refer to like part, FIGS. 1-3 show a crib soother device 10 according to an example form of the invention. The crib soother generally comprises an outer housing 20 with a display surface 22 visible through a window 24 thereof. The window 24 optionally comprises a transparent or translucent cover over the display surface 22, or optionally an opening in the housing 20. A light pattern or image is projected onto the display surface 22 by the projection of light from one or more light sources 30 through or onto an image bar 40, and onto the display surface 22. In the depicted embodiment, three LED light sources 30 are aligned in a generally linear array parallel to the lengthwise axis of the image bar 40. The image bar 40 is rotationally and/or translationally movable relative to the light source(s) 30, and comprises one or more image generating features thereon or therein, to produce a visible light pattern or image on the display surface 22. Optionally, a reflective mirror 50 or other optical element is interposed in the light path between the light source(s) 30 and the display surface 22, for example between the image bar 40 and the display surface 22. Alternatively, as shown in FIG. 4B, the display surface 22′ is a portion of the housing, for example a translucent housing portion onto which a pattern or image is projected from the rear and visible from the front.
The soother device 10 optionally comprises one or more moving and/or stationary entertainment objects 60, such as, for example, molded characters or toys mounted along or adjacent to the display surface 22, and coupled to drive elements extending through the display surface 22 to impart rotational and/or translational movement of the objects 60 relative to the display surface 22. A drive motor 70 or other motive means optionally drives the motion of both the entertainment objects 60 and the image bar 40 through a transmission system and/or one or more linkages. Alternatively, separate drive means are provided for the entertainment objects 60 and the image bar 40. The device 10 optionally also generates audible sound patterns, via a sound transducer, sound files in onboard memory, and/or speaker or other audio output 62, optionally synchronized with the visible light patterns generated, to provide soothing audible and visual stimuli. One or more onboard controls 80, 82, 84, 86 are preferably provided to allow user operation to turn the device 10 on and off, adjust the volume, and/or selectively control the audio and/or the visible light patterns generated. A remote control 90 is optionally provided to allow a parent or caregiver to control operation of the soother device 10 from a remote location via wired or wireless (e.g., IR signal, Bluetooth, radio wave, etc.) communication. The soother 10 optionally also includes a toy or entertainment component that can be manually manipulated by a child, for example, one or more buttons that light up or make noise when pressed, hanging plush toys, a rotationally mounted ball with beads inside to be spun by the child, etc.
The soother device 10 can be mounted to a crib or other support structure S, for example by a mounting strap 110 or other mounting means. In alternate forms, the device is mounted to or adjacent a bassinet, play gym, play yard, or other equipment or resting area for a child C, infant or other human or animal user. In the depicted embodiment, the mounting strap 110 has a length adjustment clip 112 that selectively couples to and releases from the housing 20. Optionally, the device 10 further includes a base 120 having one or more support feet for supporting the device upon a bedside table or other support surface. The support base 120 can be removable from the housing, or can be integrally formed therewith.
FIG. 4A shows a light transmission schematic of an example form of the soother device 10. Light (represented by linear rays) emitted from a light source 30 projects through the image bar 40, onto an arcuate reflector 50, to project an image or light pattern onto the display surface 22, which is visible through the window 24. The light bar 40 is rotated (indicated by arrow R), to vary the image or light pattern generated on the display surface 22. Example forms of image bar 40, 40′ are shown in FIGS. 5A and 5B. The image bar 40 comprises a generally solid cylindrical elongate rod having a circular cross section. The alternative image bar embodiment 40′ comprises a generally cylindrical hollow tube having material(s) and/or object(s) contained therein. The image bar 40, 40′ is preferably formed from a transparent or translucent, or partially transparent or translucent, light-transmissive material, such as for example acrylic or ABS plastic. In alternate forms, the image bar is at least partially formed of a light-reflective material. In further alternate forms, the image bar has a shape other than cylindrical, for example an elongate triangular, rectangular or polygonal prismatic element, and/or includes one or more external surface features, inclusions or irregularities such as projections, ridges, holes or the like for varying light transmission and thereby affecting the light pattern generated.
One or more image or pattern generating features 42, 42′ are provided in or on the image bar 40 to assist in generation of the visible light pattern or image, the pattern generating features 42, 42′ having a different light transmissibility than the remainder of the body of the image bar 40. For example, in the embodiment of FIG. 5A, one or more translucent or opaque wave-shaped patterns 42 are applied to an external surface and/or formed into the image bar 40, for example by application of paint, label(s), frosting, tape, co-molding of optically different materials, cutting out of the bar, carving or etching into the bar, or other means. In the embodiment of FIG. 5B, the cylinder 40′ contains a translucent or opaque liquid or granular material 44, and/or one or more pattern generating objects 46. Optionally, two or more immiscible liquid(s) and/or material(s), such as for example oil and water of different colors and/or different light transmissibility, water and sand particles, etc., are contained within the cylinder 40′ to generate the image or light pattern upon transmission of light therethrough.
Application of one or more image or pattern generating features 42, 42′ in or on the image bar 40 in a wavy or undulating pattern, for example one or more generally sinusoidal or irregular undulating wave patterns, applied about the circumference or peripheral surface of the image bar 40 results in generation of a moving pattern of light and shadow on the display surface, resembling a rippling water surface or the reflection of light from a rippling water surface when light is projected through the image bar onto a display surface and the image bar is moved relative to the light source. Such visible light patterns have been found to have a calming or relaxing effect on some infants, pacifying them and allowing them to sleep more easily.
In alternate embodiments, differing patterns may be provided for the image generating features 42, for example a zig-zag pattern, a helix or spiral pattern, a chevron pattern, a pattern of angularly offset elements, elements of different geometric shapes, or various other pattern formats. The light patterns or images generated by the image generating features 42 of the image bar may include any of a variety of moving characters, patterns, shapes, figures or the like, in addition to or instead of the rippling water patterns described above. In further example embodiments, two or more image bars may be operated in tandem, and/or interchangeable image bars can be provided for selective replacement and use. For example, a plurality of image bars can be provided in different locations and/or orientations, driven by one or more motor(s), projecting like or different image pattern(s) from one or more location(s) and/or projection angle(s) (e.g., projection from the top, bottom, left/right sides, and/or corners, etc.). The image bar(s) can be of a uniform color throughout, or can comprise two or more sections of differing colors or shades.
The light source(s) 30 can comprise one or more LEDs, incandescent or fluorescent lamps, or other light sources. The light source(s) 30 can be of a single uniform color, or alternatively of two or more differing colors, or variable color light sources. The light source(s) 30 can be operated at a constant light intensity, or alternatively can be varied between brighter and dimmer illumination states. Onboard batteries and/or an external AC power source can be utilized to energize the light source(s) 30 and the drive motor 70 for rotating the image bar 40 and actuating the entertainment objects 60. In further alternate embodiments of the invention, the light source(s) 30 and/or the reflector 50 may move, rather than (or in addition to) movement of the image bar 40.
In methods of use according to example forms of the invention, the soother device 10 is mounted to a crib or other support S, near a child C. The device 10 is activated by operation of the onboard controls 80, 82, 84, 86, and/or the remote 90. Light is transmitted through the image bar 40, and the image bar is rotated. Rotation of the image bar 40 causes variation of the light transmitted by the image bar, generating a fluctuating or wave-like image or pattern of light. The light pattern is reflected by the reflector 50 or otherwise projected onto the display surface 22, where it is visible by the child, and thereby may have a calming effect on the child and induce the child to more easily fall asleep. The image bar may be rotated at a constant or varying rotational speed, and/or can be controlled between two or more speed settings, to effect different patterns of light.
While the invention has been described with reference to preferred and example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
