Abstract
A reciprocating device for holding an infant carrier that is expandable to accommodate carriers of various sizes. The device includes a base member that is stationary with respect to a support surface and a platform that reciprocates above the base member. The reciprocation is executed by an actuator. The reciprocation of the platform on the base member is linear. The platform can include expansion trays which extend outward, increasing its usable surface area, it can be foldable between folded and unfolded positions, or it can be foldable and include expansion trays.
Description
- The invention relates to a reciprocating platform for holding infant carriers, and more specifically relates to a reciprocating platform that is expandable to accommodate different sized carriers.
- It has long been known that oscillatory motion can induce a small child, especially an infant, to sleep. Rocking has been a method used by caretakers for thousands of years to help infants fall and remain asleep. It is also well known that the movements involved with transporting an infant can help induce it to sleep. For example, the motion associated with pushing a stroller or riding in a car frequently put infants to sleep. Devices have been developed to simulate this motion mechanically. For example, electrically powered rockers which automatically swing an infant back and forth in a consistent rhythm have been developed.
- None of the methods are guaranteed to induce a child to sleep. However, once asleep, some infants will awaken once the movement is stopped. Also, the process of moving an infant from a stroller or car seat to an automatic rocker can rouse an infant. Once the child is awake, it may not return to sleep. Accordingly, there are devices which can convey motion to an infant carrier, such as a stroller or car seat, once the infant is no longer traveling.
- For example, International Patent Application Serial No. PCT/GB/00474 discloses a device with a platform that moves back and forth while pivoting to replicate rocking. The device includes a box next to the platform that houses a motor to impart the motion to the platform. The overall design of the device is large and awkward and is intended to be stationary.
- The BabySitter by Robopax is somewhat smaller and includes an actuator under the platform. However, the platform is not expandable, and the device must be as large as the platform. This can be cumbersome if the device is designed to accommodate a large stroller.
- Accordingly there is a desire for a device which can accommodate an infant carrier and has an expandable platform such that it can be made small and portable. There is also a desire for such a device to accommodate both large carriers, such as strollers, and smaller carriers, such as car seats. Further, the device may be portable, so the caregiver can transport it easily to another location or destination outside the care giver's home.
- The invention provides a reciprocating device for holding an infant carrier that is expandable to accommodate carriers of various sizes. The device includes a base member that is stationary with respect to a support surface and a platform that reciprocates above the base member. The reciprocation is executed by an actuator. The reciprocation of the platform on the base member may be linear. Accordingly, the actuator can be a linear actuator, or a rotating motor with linkage to convert the rotating motion to a linear motion.
- The device may include one or more features which allow it to expand in either length, width or both. The platform can include expansion trays which may extend outward, increasing the usable surface area of the platform. The expansion trays are movable between a first contracted position, where the platform is small and a second expanded position. The expansion trays may slide relative to the rest of the platform.
- Alternatively, the platform may be foldable, such that it can be folded and smaller or open and larger. The device may include various elements to support the unfolded section of the platform when the platform is open. For example, the base member can be expandable, a second base member may be included, or the platform can have its own support members, such as wheels.
- To accommodate a wide range of different sized baby carriers, the device may include more than one expansion feature. The device can be both foldable and include an expansion tray. The expansion trays can be used when the device is in the unfolded position. In the expanded position, the device is open (unfolded) and the expansion trays are in an extended position. Each side of the folded platform is supported by a base member.
- The expansion trays can be slidably connected to the rest of the platform. To keep the expansion trays in a desired position they can be temporarily fixed in place. For example, the connection between the expansion tray and the platform can include spring-loaded locks, such that the trays can lock in both an extended and a contracted position.
- The platform is also slidably connected to the base members, with each half of the foldable platform connected to a different base member. For instance, a first section of the platform can be slidably connected to a first base member and a second section of the platform can be slidably connected to a second base member. Rollers can be included between the platform and base members, such that the reciprocation of the platform is smooth.
- The platform, including an expansion tray, can be foldable about a hinge or pivot joints. To fold the device, the second section of the platform is rotated about the hinge such that it rests above the first section of the platform. The hinge is not limited to a specific embodiment and only defines the part of the platform through which the two sections are foldably connected. The hinge can be formed integrally with one of or both of the platform sections, or can be separate parts attached to the sections of the platform. Consequently, the second base member, which is attached to the second section of the platform, is also rotated about the pivot joint. Thus, when the device is in the folded position the second base member is above the platform and forms the support surface for a baby carrier. Accordingly, the second base member may be designed to have a surface which acts as the bottom when in the open position, but acts as the carrier surface when in the folded position.
- In the folded position the device is smaller and can be portable. Accordingly, the device can include a handle or strap for added convenience to the user.

In the compact position,platform 40 is more easily transported and takes up less space. Eachexpansion tray 66 also has an extracted position increasing the surface ofplatform 40.Expansion tray 66 may slide away from the rest of theplatform 40 into an extracted position to form an expanded position ofplatform 40. In the illustrated embodiment part of the main body of the platform is exposed between the expansion trays. However, theexpansion trays 66 can each be half the width of the platform, such that they touch when in the compact position. In the compact position, theexpansion tray 66 may be held under, above, or within the rest of theplatform 40. Theexpansion tray 66 may be movable in an up and down direction once in the extracted position to align with the top of the platform. For example, ifexpansion tray 66 is held beneath the rest of theplatform 40 in the compact position, it may be raised when placed in the extracted position to be flush with the top of theplatform 40. InFIGS. 1 a and 1 b theplatform 40 includes twoexpansion trays 66, each of which is shown above the rest of the platform and is operable to slide over the platform. -
FIGS. 2 a and 2 b show another embodiment ofreciprocating device 1.Platform 40 includes two pivotally connectedsections device 1,first section 44 is beneathsecond section 46, as shown inFIG. 2 a. In an expanded position,second section 46 is adjacentfirst section 44.Platform 40 may include ahinge 100 connectingfirst section 44 andsecond section 46. Asecond base member 10′ may be placed undersecond section 46 to provide support, seeFIG. 2 b. As shown inFIG. 2 a, thesecond base member 10 may be held below thefirst base member 10 whendevice 1 is in the compact position. Alternatively,second base member 10 may be held above platform 40 (See, for example, the embodiment illustrated inFIG. 12 ) - Other methods can also be used to support
second section 46. For example, as shown inFIG. 3 ,base member 10 may includerails 12 which extend therefrom. Therails 12 can be extended to supportsecond section 46 in the expanded position, or rails 12 can be held withinbase 10 whendevice 1 is in the compact position. - Another embodiment, shown in
FIGS. 4 a and 4 b, is thatsecond section 46 supports itself. For example,second section 46 may includewheels 42, which reach the floor whenplatform 40 is open andsecond section 46 is adjacentfirst section 44. Thewheels 42 may be positioned such that they do not interfere withbase member 10 as theplatform 40 oscillates.Wheels 42 may be retractable, such that they do not obstruct a platform surface provided bysecond section 46 when in the compact and folded position. - The
device 1 may be portable so that the care giver of the child can take the device to locations outside of the care giver's home. The expandability of theplatform 40 surface allows the device to be small such that it is easy to carry. Further, thedevice 1 can include a handle (seeFIG. 12 ), so that it can be lifted and moved easily. - The
device 1 may include additional features to aid in calming the infant. For example,device 1 can include a system for playing music.Device 1 can include speakers for playing music to soothe the infant. Pre-recorded music can be stored in a memory withindevice 1 to be played over the speakers. Additionally,device 1 may include a radio receiver to receive AM, FM or satellite music broadcasts. Similarly,device 1 may include a receiver for other wireless signals, such as Wi-Fi. Further the device may include a signal port to receive audio signals from an external device. For example,device 1 may include an electrical cable to connect to the headphone port of an audio device, such as a portable audio player or computer. Alternatively,device 1 can include a docking station for a portable music player, such as an MP3 player. - The oscillation of
device 1 can be linear, such that the platform oscillates back and forth. The speed of the motion may be uniform back and forth or it can be sinusoidal such that the platform moves faster through the middle of its path. Alternatively, the platform can oscillate in a non-linear manner, for instance the platform may translate in a circle or other shape. Further, the platform can twist or rock as it moves. The motion can be made to replicate the motion of a car or rocking in a care giver's arms.Device 1 may include controls for changing the motion of the platform. The controls can change the overall speed of the motion, or change the path of the motion. Further,device 1 may be configured to oscillate according to the rhythm of music being played through the speakers, if provided. - The details of a specific embodiment of the invention which has a
platform 40 that includes bothexpansion trays 66 as well as first andsecond sections FIGS. 5-13 and described herein.Device 1 is shown inFIG. 5 in the fully expanded position.Platform 40 is folded open such thatsecond section 46 is next tofirst section 44.Expansion trays 66 are shown in an extended position providing the largest possible platform area ofdevice 1. In the most expanded position, as shown,platform 40 is wider than thebase members 10 becauseexpansion trays 66 are extending out fromplatform 40. Theexpansion trays 66 overhang thebase members 10.Actuator 70 is held in ahousing 72 that is fixed toplatform 40. In the operation of this embodiment,actuator 70,housing 72 andplatform 40, including bothsections expansion trays 66, oscillate with respect to thebase members 10. The movement ofdevice 1 in the open and expanded position is shown inFIGS. 6 a-6 c. In the most expanded position shown inFIG. 5 ,device 1 is sized to accommodate large strollers or baby carriages. - The
expansion trays 66 may be fixedly attached to the rest ofplatform 40 in such a way that they are slidable between a retracted position and an extracted position. As shown inFIG. 7 a, theexpansion trays 66 may be held on the platform using a peg and slot. One ormore pegs 68 are included on eachexpansion tray 66. Thepeg 68 rides in aslot 58 formed inplatform 40, shown in detail inFIG. 7 b.Slot 58 may have an open bottom such that awasher 62, with a diameter larger than the width ofslot 58, can be attached to peg 68 on the bottom side ofplatform 40. This arrangement allowspeg 68 to move back and forth withinslot 58, but prevents peg 68 from being removed entirely fromslot 58.Peg 68 may be lockable withinslot 58 at either end, corresponding to the extracted and retracted positions. A mechanism for lockingpeg 68, and thusexpansion tray 66, in one of the extracted and retracted positions could be as simple as a leaf spring (not shown) or more complex. - Of course, the location of the
peg 68 andslot 58 may be rearranged, such that thepeg 68 is part of the main body of theplatform 40 and theslot 58 part ofexpansion tray 66. Likewise, other mechanisms and designs may be used to fix theexpansion tray 66 onto theplatform 40 while allowing it to slide. The shown and described peg and slot embodiment is exemplary. If the user does not require such a large platform, theexpansion trays 66 may be placed and held in the retracted position, as described below. - The connection used for fixing the
platform 40 ontobase member 10 may be similar to that used to attachexpansion tray 66 ontoplatform 40, as shown inFIG. 8 , such thatplatform 40 itself may be fixed to and slidable with thebase member 10. Accordingly, theplatform 40 may include one ormore pegs 48 that ride within one or morecorresponding slots 18 in thebase member 10. Again, a washer 22 (FIG. 11 ) can be included to holdpeg 48 withinslot 18. This allows eachpeg 48 to slide back and forth withinslot 18 as theplatform 40 oscillates. - For added stability, each
base member 10 may include abar 24 that runs its length and fits within acomplimentary trench 54 in theplatform 40, illustrated inFIG. 11 . Thebar 24 of onebase member 10 fits in atrench 54 offirst section 44 and thebar 24 of theother base member 10 fits in atrench 54 ofsecond section 46. Though thebase members 10 are shown inFIG. 8 as including abar 24 and peg slots, while the complimentary platform section is shown including a trench and pegs, these features may be arranged in any fashion. For example, thebar 24 may be included on either the base member 10 (as shown) or on theplatform section pegs 48 may be included on either thebase member 10 orplatform 40. -
Rollers 20 may be included on either theplatform 40 orbase member 10 to reduce friction between these parts as theplatform 40 is oscillated. In the illustrated embodiment a plurality ofrollers 20 are attached to eachbase member 10. Smooth flat surfaces are included on theplatform sections paths 50 corresponding torollers 20. Eachroller 20 may be recessed in acavity 21 exposing only a small rolling surface above the surface of thebase member 10, depicted inFIG. 9 . The depth ofroller 20 within thecavity 21 determines the gap formed betweenplatform 40 andbase section 10. - As stated above,
actuator 70 is held in ahousing 72 that is fixed toplatform 40. Thehousing 72 may be larger than the actuator, as shown inFIG. 7 a, to provideconvenient storage space 74. Thestorage space 74 may be used to hold a power adapter or battery pack fordevice 1 or anything desired by the user. - In the illustrated embodiment,
actuator 70 is a motor that is fixed withinhousing 72 relative toplatform 40. Asplatform 40 oscillates so canmotor 70.Motor 70 is coupled to adrive arm 80 that interacts with one of thebase members 10 to driveplatform 40 in an oscillatory motion. Thebase member 10 which interacts withdrive arm 80 is described as thefirst base member 14, while the other is described as thesecond base member 16. Thedrive arm 80 is positioned belowplatform 40 and is coupled tomotor 70 through a hole in the platform. Drivearm 80 is attached at afirst end 86 to ashaft 84 that is driven bymotor 70. Asmotor 70 turns,drive arm 80 rotates about theend 86 which is attached to theshaft 84. - The operation of the actuator is illustrated in
FIG. 10 . Thesecond end 88 ofdrive arm 80 has anextension 82 attached thereto. Relative to themotor 70 andplatform 40,extension 82 travels in a circular motion asdrive arm 80 rotates.Extension 82 is held in a well 76 in thefirst base member 14. Well 76 is a substantially linear groove with side walls 78 extending down from a surface offirst base member 14. Well 76 is arranged such that its length is perpendicular to the direction of oscillation ofplatform 40. Asdrive arm 80 rotates,extension 82 moves back and forth within well 76. Thus, the motion ofextension 82 is linear relative tofirst base member 10. The movement ofextension 82 within well 76 compensates for a first component of the rotational motion ofdrive arm 80. The second component of the rotational motion ofdrive arm 80 is translated to the oscillation of theplatform 40. For example, ifextension 82 begins at one end of well 76 it will pushplatform 40 in a first direction as theextension 82 moves toward the center of the well 76. Whenextension 82 reaches the center of well 76,platform 40 is at a peak in its oscillatory motion. Asextension 82 travels to the other end of well 76,platform 40 is pulled back to its central position. While theextension 82 goes back to the first end of well 76,platform 40 moves toward and back from a second peak in its oscillatory motion. Ifmotor 70 rotates at a constant rate, the trigonometric relationship between the well 76 andextension 82causes platform 40 to have a linear motion with a sinusoidal rate. -
Extension 82 may include adrive wheel 83 which rides against the sidewall 78 ofwell 76. Drivewheel 83 reduces friction betweenextension 82 and well 76. Thus, a smooth, even motion is imparted inplatform 40 asdrive arm 80 rotates. In a preferred embodiment,platform 40 oscillates with respect to bothfirst base member 14 andsecond base member 16. However, actuator 70 and drivearm 80 act only on theplatform 40 andfirst base member 14. Thus,platform 40 does not inherently oscillate relative tosecond base member 16. Therefore, atemporary attachment member 98 may be included to securesecond base member 16 tofirst base member 14 whendevice 1 is in an open position. Accordingly,platform 40 oscillates with respect to bothbase members 10. Thetemporary attachment member 98 may be one or more magnets linking thebase members 10. -
FIG. 12 illustrates that each of thebase members 10 may include agrip section 90 includingfeet 92. Thefeet 92 shown in the figures are formed of rubber which has high traction and helps stabilizedevice 1 on the support surface. Even if the infant carrier is large and heavy, such that its movement on theplatform 40 creates large changes in momentum, thegrip section 90 holdsdevice 1 in place. - The platform
first section 44 andsecond section 46 may be held together bypivot joints 102 which act as ahinge 100. To placedevice 1 in the folded section, shown inFIG. 11 , the user rotatessecond section 46 ofplatform 40 andsecond base member 16 abouthinge 100 as shown inFIG. 12 . When in the foldedposition device 1 may be used to hold a smaller infant carrier, such as a car seat.Grip section 90 ofsecond base member 16 securely holds the infant carrier in place ondevice 1. To avoid interference with any infant carriers placed ondevice 1, thefeet 92 may be included at the corners ofgrip section 90. In the folded position, it is preferable ifsecond base member 16 oscillate withplatform 40, such as illustrated inFIG. 13 . In the illustrated embodiment,actuator housing 72 is tall enough that it may include atemporary attachment member 98 to securesecond base member 16 to actuatorhousing 72. Becauseactuator housing 72 is fixedly attached toplatform 40, thetemporary attachment member 98 ensures thatsecond base member 16 is fixed with respect toplatform 40. - In the folded position,
device 1 is smaller and more portable. Ahandle 96 may be included ondevice 1 for easier carrying. Thehandle 96 preferably extends to the side ofdevice 1 such that it is in a vertical orientation when being carried byhandle 96. The side ofdevice 1opposite handle 96 may include a floor pad (not shown) to securedevice 1 when set down temporarily during transport. As shown inFIG. 12 , handle 96 may be an extension ofplatform 40. In this embodiment,second base member 16 is kept from moving in the oscillation direction bytemporary attachment member 98 andactuator housing 72. Similarly,first base member 14 is held in place by the static torque ofmotor 70. Thus, whendevice 1 is carried byhandle 96, the parts which oscillate with respect to one another are held in place. - Although the preferred form of the invention has been shown and described, many features may be varied, as will readily be apparent to those skilled in this art. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
