DETAILED DESCRIPTION
Persons skilled in the art will readily appreciate that various aspects of the present disclosure can be realized by any number of methods and apparatus configured to perform the intended functions. It should also be noted that the accompanying drawing figures referred to herein are not necessarily drawn to scale but may be exaggerated to illustrate various aspects of the present disclosure, and in that regard, the drawing figures should not be construed as limiting.
FIGS. 1-4 illustrate a nursing chair system 50 according to an embodiment of the present disclosure. Generally, the nursing chair system 50 includes a nursing chair 100 and a footrest 150. The chair 100 is configured to support a seated adult human, that is, an infant's mother, in a seat portion 110 (also interchangeably referred to herein as a seat 110). The seat portion 110 is rotatably coupled to a pedestal portion 105 about a vertical axis (not shown). As such, the seat portion 110 is rotatable, by 360 degrees, relative to the pedestal portion 105 about the vertical axis. The pedestal portion 105 includes a lifting mechanism 115 (for example, a pneumatically-driven actuator or an electrically-driven actuator) for raising and/or lowering seat portion 110. The seat portion 110 is also adjacent to a first, or right, armrest portion 120, a back portion 130, and a second, or left, armrest portion 140. In some embodiments and as illustrated, the first armrest portion 120 and second armrest portion 140 have like features and/or are mirror images of each other. More specifically, the first armrest portion 120 and the second armrest portion 140 may both be adjustable to facilitate nursing an infant on either of a mother's breasts. In other embodiments, the first armrest portion 120 and second armrest portion 140 have different features than each other. More specifically, one of the first armrest portion 120 and the second armrest portion 140 is adjustable, and the other of the first armrest portion 120 and the second armrest portion 140 is not adjustable.
FIGS. 1-4 illustrate the chair 100 with the first armrest portion 120 and the second armrest portion 140 in first, or “resting” or “normal”, positions. In such positions, the first armrest portion 120 and the second armrest portion 140 are generally positioned perpendicularly relative to the seat portion 110 and the back portion 130. Further, in such positions a first upper surface 125 and a second upper surface 135 of the first armrest portion 120 and the second armrest portion 140, respectively, are configured to support an arm (more specifically, an elbow and/or forearm) of a mother seated in the chair 100.
FIGS. 5-8 illustrate the chair 100 with the first armrest portion 120 in one of various second, or “infant support”, positions. In the infant support positions, a first side surface 155, or an inner side surface 155, of the first armrest portion 120 is configured to support an infant thereon. More specifically, in the infant support positions the first side surface 155 is configured to support an infant such that the infant's head is generally disposed above the seat portion 110 and the infant's feet generally point away from the chair 100. In the infant support positions, the inner side surface 155 may be disposed, as illustrated, at a slight angle to a horizontal plane (for example, about 15 degrees, about 30 degrees, or about 45 degrees) or, alternatively, in the horizontal plane. In some embodiments, the first side surface 155 is cushioned and/or includes strap or harness (not shown) to facilitate comfort and/or securement, respectively, of an infant supported on the first side surface 155. To move to an infant support position, the first armrest portion 120 is translatable relative to the seat portion 110 along to a first, or vertical, axis 160, rotatable about the vertical axis 160 (for example, by about 45 degrees), rotatable about a second axis 165 substantially parallel to the first upper surface 125, and translatable along the second axis 165. Although it is not specifically illustrated, the second armrest portion 140 may similarly occupy various second, or infant support, positions and include similar components to facilitate supporting an infant in such positions.
FIG. 9 partially illustrates the first armrest portion 120 and a first support 170 that couples the first armrest portion 120 to the seat portion 110 (shown elsewhere). The first support 170 is actuatable to translate the first armrest portion 120 relative to the seat portion 110 along the vertical axis 160. More specifically, the first support 170 is a telescoping structure that carries a linear actuator 175 (for example, an electrically-driven linear actuator). Alternatively, the first support 170 may take other forms. For example, the first support 170 may carry another type of linear actuator 175, such as a pneumatically-driven linear actuator. As another example, the first support 170 may take the form of a pair of slidable rails.
FIG. 10 partially illustrates the first armrest portion 120 and components that facilitate moving the first armrest portion 120 from the normal position, as illustrated, to an infant support position. Specifically, FIG. 10 illustrates a first user input 180 (for example, a button or a lever) that is actuatable to energize the linear actuator 175 (shown elsewhere) of the first support 170 and thereby translate the first armrest portion 120 relative to the seat portion 110 (shown elsewhere) along the vertical axis 160. The first support 170 couples to a multiple degree-of-freedom joint 185, such as a ball joint, which in turn couples to the first armrest portion 120. The joint 185 permits the first armrest portion 120 to rotate relative to the first support 170 about the vertical axis 160 and the second axis 165. The joint 185 couples to the first armrest portion 120 via a slider 190 carried on a track 195, and the slider 190 is translatable along the track 195 to translate the first armrest portion 120 along the second axis 165. As illustrated, these components may be partially or fully recessed within the first armrest to provide a less conspicuous appearance. More specifically, the track 195, slider 190, and the joint 185 may be recessed in a horizontal channel 200 and the first support 170 may be partially recessed in a vertical channel 205 coupled to the horizontal channel 200. Alternatively, these components may be disposed externally from the first armrest portion 120.
FIGS. 11-14 illustrate the chair 100 with (1) the first armrest portion 120 in one of various third, or “adjustment”, positions and (2) the second armrest portion 140 in a fourth, or “retracted”, position. In the adjustment positions, an upper portion 210 of the first armrest portion 120, which includes the first upper surface 125, is moved relative to a lower portion 215 to facilitate providing support for a mother's arm in different seated positions (for example, leaning to one side, sitting completely upright, and the like). The upper portion 210 is movable relative to the lower portion 215 in a first, or front-to-back, direction 220 and a second, or side-to-side, direction 225.
Referring to FIG. 15, to facilitate movement of the upper portion 210 relative to the lower portion 215, the first armrest portion 120 includes a first track 230 coupled to the lower portion 215, a first slider 235 that translates along the first track 230 in the first direction 220, a second track 240 coupled to the first slider 235 opposite the first track 230, and a second slider 245 that translates along the second track 240 in the second direction 225, the second slider 245 coupling to the upper portion 210 opposite the second track 240.
Referring again to FIGS. 11-14, in the retracted position the second armrest portion 140 is generally disposed even with and below the seat portion 110 to facilitate entry to and egress from the seat portion 110. To facilitate movement of the second armrest portion 140 from the retracted position to the normal position and vice versa, a second support 250, which couples the second armrest portion 140 to the base portion 110, is pivotable relative to the seat portion 110 about a third axis 255 (for example, by about 90 degrees). The seat portion 110 and/or the second support 250 may include a locking mechanism (not shown) that is normally engaged to inhibit the second support 250 and the second armrest portion 140 from pivoting relative to the seat portion 110 about the third axis 255 and selectively disengageable to permit movement from the normal position to the retracted position and vice versa.
Although it is not specifically illustrated, the second armrest portion 140 may similarly occupy various third, or adjustments, positions and include similar components to facilitate moving to and from such positions. Although it is not specifically illustrated, the first armrest portion 120 may similarly occupy a fourth, or retracted, position and include similar components to facilitate moving to and from such position.
In some embodiments and as illustrated in FIGS. 16-20, the chair 100 further includes a retractable privacy screen 260. FIGS. 16-19 illustrate the privacy screen 260 in a use, or “privacy”, position in which the privacy screen 260 may obscure an infant and a mother during breastfeeding. FIG. 20 illustrates the privacy screen 260 in a retracted position in which the privacy screen 260 is disposed completely behind the seat portion 110. The privacy screen 260 may move from the privacy position to the retracted position by pivoting over the seat portion 110 and collapsing upon itself. Similarly, the privacy screen 260 may move from the retracted position to the privacy position by pivoting over the seat portion 110 and expanding. Although it is not specifically illustrated, one or both of the first armrest portion 120 and the second armrest portion 140 may occupy an infant support position while the privacy screen 260 is in the privacy position.
In some embodiments, the nursing chair system 50 includes additional features that facilitate ease-of-use and/or convenience. In some embodiments, one or both of the first armrest portion 120 and the second armrest portion 140 may include storage space 265 (see FIG. 10) for holding, for example, two or three bottles. The storage space 265 may be a ‘cold’ storage space 265 cooled by a refrigeration unit (not shown) and/or by including reusable cold packs (not shown) within the storage space 265. In some embodiments, the nursing chair system 50 may include one or more antimicrobial materials and/or linings, particularly for the storage space 265. In some embodiments, the nursing chair system 50 may include soft LED lighting (not shown) in the sides of the chair 100 to facilitate late night feedings. In some embodiments, the nursing chair system 50 may include an infant scale (not shown) that slides in and out near the pedestal portion 105 for weighted feedings. In some embodiments, the nursing chair system 50 may include one or more power outlets, USB ports, and/or other like electronic connections at the pedestal portion 105 and/or side(s) of the chair 100 to facilitate, for example, charging phones, plugging in a nursing pump, or the like. In some embodiments, the nursing chair system 50 may include one or more spill- and stain-proof material for any of the seat portion 110, the back portion 130, armrest portions 120, 140, and the footrest 150.
