Abstract:
An improved portable baby carrier rocking system in which allows almost all existing car seat carriers, baby carriers and baby bassinets to be attached to it. This baby carrier rocker mounts underneath the baby carrier and attaches to it by a simple strap. This baby carrier rocker can be battery operated or powered by an external power supply. It has different rocking speed settings and it will rock any bottom shaped carrier profile from flat to curved. An electric motor drives an offset link in which raises and lowers four supporting arms underneath the baby carrier, thus rocking the carrier back and forth from its center pivoting position. This baby carrier rocker has extendable and retractable legs in which flips out for greater rocker stability. Its novel compact size makes this rocker easily transportable and can be used in small confined areas like in restaurants, camping tents, in crowded rooms, areas etc.

CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a non-provisional application of Applicant&#39;s provisional application Ser. No. 61/401,408 filed on 13 Aug. 2010. 
     
    
     BACKGROUND OF INVENTION 
       [0002]    Existing baby swings and rockers today have several problems in which limits their usage or accessibility. They are either large in size in which makes them difficult to carry, occupies too much floor area, or they cannot suite most existing car seat carriers, baby carriers, or baby bassinets. The basic swing is a very useful and important device for babies and is used in almost every baby&#39;s household. The problem today is being able to bring this rocking action to a tight location like at a restaurant, in a camping tent or trailer or in a tight public area. Also to have it small in size in order to be able to carry it on you in a small bag, thus leaving your arms free. Most rocking or swinging apparatus are large in size and many do not accept all types and styles of existing car seat and baby carriers. This is also a problem due to many families owning more than one type of baby carrier. Also today portable baby bassinets are becoming more popular and there are few existing methods for rocking them with a portable device. 
         [0003]    Some existing so called “portable” swings or rockers are designed the same as the original larger common swings, but made smaller. Some of these designs do fold partly, but normally very little. Commonly the two swing side frames fold together. All these folding swings normally do not accept third party baby carriers or bassinets. They either do have a built in one, in which is big and balky, or they can only accept their own brand name type. U.S. Pat. No. 7,037,205 B1 and U.S. Pat. No. 6,857,966 B2 and U.S. Pat. No. 6,520,862 B1 and U.S. Pat. No. 6,343,994 B1. 
         [0004]    There have been a few other types of rockers such as ones that have a movable platform in which one end is fixed and the other end moves up and down. This does not produce a “rocking” affect as you&#39;re only lifting one end up and down. To achieve a true rocking motion, both ends should move up and down opposite to each other. U.S. Pat. No. 6,574,806 B1 and U.S. Pat. No. 4,985,949 and U.S. Pat. No. 3,992,731 and U.S. Pat. No. 4,656,680 and U.S. Pat. No. 3,653,080. 
         [0005]    Another existing system is by gliding a flat surface horizontal to the floor, thus a back and forth motion. Again, this is not a “rocking” motion as with this novel invention here. 
         [0006]    This new novel idea, rocks the baby seat carrier or bassinet from underneath, pivoting around a centre point, at the centre of the baby carrier, rocking it equally in both directions in an up and down motion. 
         [0007]    The foregoing has outlined some of the more pertinent objects of the invention. These objects should be construed to be merely illustrative of some of the more prominent features and applications of the intended invention. Many other beneficial results can be attained by applying the disclosed invention in a different manner or by modifying the invention within the scope of the disclosure. Accordingly, other objects and a fuller understanding of the invention may be had by referring to the summary of the invention and the detailed description of the preferred embodiment in addition to the scope of the invention defined by the claims taken in conjunction with the accompanying drawings. 
       BRIEF SUMMARY OF THE INVENTION 
       [0008]    Accordingly, the after mentioned problems and difficulties are obviated by the present invention. This is a novel baby carrier rocker in witch all types of baby carriers and bassinets attach to the top of it and it will rock it back and forth at different predetermined speeds. It is small in size, easily portable, and is stable due to its folding and retractable legs. 
         [0009]    Therefore it&#39;s among the primary objectives of this invention to be mounted underneath and to accept existing car seats, baby carriers and most portable baby bassinets. 
         [0010]    A second object of this invention is to be physically as small in size as possible for easily carried and transported. Also to occupy the least amount as space when operating in small or restricted space areas. 
         [0011]    A third objective of this present invention is to have its legs and attachments easily foldable without the use of any tools and/or the removal of any pieces. 
         [0012]    A forth objective of this invention is for there to be no adjustments necessary to adapt for different baby carrier styles and configurations. 
         [0013]    A fifth object of this rocking device is to maintain a minimum baby carrier height above the rocking surface. 
         [0014]    A sixth object is to rock the baby carrier from its centre position and not from just one end, thus creating a natural up and down rocking motion. 
         [0015]    Another objective is for this rocking device to accept all types of carrier bottom profiles, regardless if its curved or straight in nature. 
         [0016]    Still another objective of this invention is not to have any overhead obstructions above the carrier in order to have full access and maximum visibility of the baby. 
         [0017]    A last objective is to have several predetermined rocking speed settings and to be able to accept rechargeable batteries or regular batteries and/or from an external plug in power supply or from a car battery system.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0034]      FIG. 1  shows an isometric view of a typical baby seat carrier seat  15 , attached to the top of the invention of the baby carrier rocker. The baby seat carrier  15  sits on and being supported by four swivel arms  8  and  9 . A strap  13 , attached to the two strap slots  50  on the two sides of the rocker plate  27 , are placed around the baby seat carrier seat  15 , and through its two existing buckle slots  41  and connected together by a cam buckle  28 . Any other kind of attachment device could be used instead of using the cam buckle  28 . This strap  13  then is tightened, and thus fixing the [carrier seat] baby seat carrier  15  to the four arms  8  and  9  below. Another adjustable strap combination not shown here, could be to add a strap from the front of the roller plate  27 , to the front of the baby seat carrier  15 , and another strap from the rocker plate  27  to the rear of the baby seat carrier  15  for greater stability and security. The baby carrier rocker has two extendable front legs  3 , and two side legs  5  for added stability to this rocking system shown here in its extended/operating position. There is a power on/off switch  19  mounted on the side of this baby carrier rocker that has three positions in which two different rocking cycle rates could be selected. Any type of selector switch or Potentiometer could be used with more speed settings instead of this switch  19 . Beside this on/off switch  19 , there is a power jack  22 . This power jack  22  is used to accept external power sources, such as but not limited to wall transformers, power adaptors, car cigarette power outlets and remote battery supplies. 
         [0035]      FIG. 2 , shows an isometric view of the baby carrier rocker in its folded/collapsed position. Here the side legs  5  are folded into the side of the frame  1 . Then the two front legs  3  are folded backwards around the center axis of the fix front leg pin  4 , into the frame  1  as shown. The leg notch  42  in the front leg  3 , slides inside the leg notch  42  in the side leg  5 , thus preventing the side leg  5  from accidentally folding outwards during transport. 
         [0036]    Both the LH.  9  Arms and the RH. Arms  8 , swivel around the center axis of the arm pins  11 . These arms  8  and  9  are locked into place by a clamp block  12  located in between them. The clamp block  12  is slid upwards by placing the tip of your finger inside of the notch  51 , thus allowing the arms  8  and  9  to rotate around the arm pin  11 . Then the clamp block  12  is pressed back down against the rocker plate  27 , thus binding the arms  8  and  9  into position. Each arm  8  and  9  does have a rubber grip pad  10  adhered to the top of them. These grip pads  10  will come into contact with the baby seat carrier  15  as shown in  FIG. 1 . The rocker plate  27 , does rock back and fourth along the center axis of the rocker plate pin  24 . These two rocker plate pins  24 , opposite to each other, are rigidly attached to the frame  1 . 
         [0037]      FIG. 3 , shows an isometric view of the baby carrier rocker in its open, operational position. Here the two front legs  3  are pivoted around the front leg pin  4 , to its forward position. Then the side legs  5  are pivoted outwards to 90 degrees to the frame  1 . Other obvious methods of extending these legs could be used such as sliding them outwards or removing them and snapping or fastening them into position. Then the two clamp blocks  12  are lifted upwards, by placing the tip of your finger inside of the notch  51 , away from the rocker plate  27 , thus allowing all four arms  8  and  9  to rotate outwards around each arm pin  11  respectively. Once these arms  8  and  9  are in there outwards, perpendicular position with the rocker plate  27 , the two clamp blocks  12  are then pressed downwards making contact to the rocker plate  27 . These four arms  8  and  9  are now locked into position. Other methods of extending and locking the four arms  8  and  9  could be used, like snapping them into position; sliding them; having them removable or fastening them into either the open or closed position. The general concept still remains the same of being able to extend the arms  8  and  9  outwards then being able to collapse them again. 
         [0038]      FIG. 4 , shows a rear side view of  FIG. 3 . A notched out baby carrier  43  is attached by the strap  13  to the four arms  8  and  9 . 
         [0039]    The rocker plate  27 , pivots around the two rocker pin  24 . This rocking action raises and lowers both ends of the rocker plate  27 , as shown by the rocker angle  45 . 
         [0040]    This rocking action will in turn also rock the notched out baby carrier  43  back and fourth. Under the frame  1 , there is a clearance  46 , in which only the two front legs  3  and the side legs  5  do make contact with the supporting surface  47 . This clearance  46  allows the supporting surface  47  to be uneven, or not perfectly flat. Also this clearance  46  ensures that both the front legs  3  and side legs  5  are in contact with the supporting surface  47  for maximum stability. Both ends of the straps  13  are rigidly fixed to the rocker plate  27  through the strap slot  50 . 
         [0041]      FIG. 5 , shows a breakaway isometric view of the baby carrier rocker invention. Here it&#39;s in its open, operational configuration with all its legs  3  and  5 , and its arms  8  and  9  in the outwards, extended position. Inside shown is an electric gear motor  20 , in which is mounted to its motor support  18  in which is mounted to its base  2 . The base  2  is the bottom of this invention. At the rear of the base  2 , there is a battery cover  7  in which is removable. This battery cover  7 , retains the removable battery pack  23  in which is housed inside of the frame  1 . This battery pack  23  can be removed for recharging or for battery replacement. The motor  20  rotates at a predetermined output speed the lift ring  16 . The lift ring  16  is fixed to the output shaft of the motor  20 . As the lift ring  16  rotates, a fixed lift ring pin  48  also rotates at a pre-determined distance from the center axis of the motor  20  output shaft. The yoke  49  pivots around the center axis of the lift ring pin  48 . As the lift ring  16  rotates, the yoke  49  will move upwards and downwards, as it will in turn move the lift pin  14  also upwards and downwards accordingly. The lift pin  14  is fixed to the rocker plate  27 , thus when the lift pin  14  moves up and downwards, the rocker plate  27  will also lift upwards and downwards, through the center axis of the two rocker pins  24 . In turn this movement will create a controlled rocking action of the rocker plate  27  and its four arms  8  and  9 . 
         [0042]    The speed of this rocking action is determined by its predetermined or variable speed setting of its switch  19 . Also there is a current limiting device with in the circuit in order to safety cut the power to the motor  20  if this invention should get jammed or should tilt over for any reason. 
         [0043]      FIG. 6A , shows the side view of a typical baby seat carrier seat  15 , sitting on top of both the LH. Arm  9  and the RH arm  8 . Both of these LH. Arm  9  and RH. Arm  8  has a rubber grip pad  10  adhered to them. These two arms  8  and  9  have a sloped top surface to better match the curved rocker bottom profile  33 . These grip pads  10  help increase the friction, thus reducing the slippage between the rocker bottom  33  and the two arms  8  and  9 . 
         [0044]      FIG. 6B , show a side view of another style of a typical notched out baby carrier  43 . The principle is the same as in  FIG. 6A . 
         [0045]      FIG. 6C , shows an isometric view of  FIG. 6A . 
         [0046]      FIG. 7 , here shows another method of preventing a typical baby seat carrier  15  from sliding on top of the four arms  8  and  9 . Here shows a bottom isometric view of a typical baby seat carrier seat  15 , over top of the LH. Arm  9  and the RH. arm  8 . Both of these arms  9  and  8  do have a layer of hook Velcro  25  adhered to the top of them. A piece of loop Velcro  26  is then adhered to the rocker bottom  33 , at the same center distance as the two arms  8  and  9 . When the hook Velcro  25  comes in contact with the loop Velcro  26 , they do adhere together, thus helping preventing the rocker bottom  33  from sliding or moving on top of the two arms  8  and  9 . 
         [0047]      FIG. 8A , shows an isometric view of the baby carrier rocker assembly with a typical bassinet adaptor frame  35  attached to it. This bassinet adaptor frame  35 , is flat and has an end stop  44  on top either at one end or at both ends of it. This end stop  44  is to prevent the bassinet  34  from sliding forward while rocking. 
         [0048]    This bassinet adaptor frame  35  will support the bottom of a typical bassinet  34 . This bassinet adaptor frame  35  fits in-between and is supported by the four arms  8  and  9 . The strap  13  is fixed to the strap slot  50  on both sides of the rocker plate  27 . It passes underneath the bassinet adaptor frame  35 , then upwards around the top of the bassinet  34 . Then the cam buckle  28  connects both ends of the straps  13  firmly together. Any other type of connection could also be used here. By pulling the strap  13  tight, the bassinet  34  will be pressed downwards onto the top of the bassinet adaptor frame  35 , and this frame  35  will then be pressed down tightly on to the top surface of the rubber grip pads  10  on each of the arms  8  and  9 , thus rigidly fastening the bassinet  35  to the baby seat rocker. The end plate  44  is used to help prevent the bassinet  34  to slip or slide forward due to the rocking motion of the baby seat rocker. 
         [0049]      FIG. 8B , shows the side view of  FIG. 8A , but with the bassinet  34  in its proper position. You can see how the end plate  44  is preventing the forward movement of the bassinet  34 . A second end plate  44  could also be incorporated into this design on the opposite end of the bassinet adaptor frame  35  as shown. Shown is an adjustable end plate  44  in which can extend, lock and retract to best suite the overall length of the bassinet  34 . This type of adjustable end plate could also be used in the front as well. 
         [0050]      FIG. 8C , shows an isometric view of  FIG. 8B . 
         [0051]      FIG. 9A , shows the top and side view of another method of a foldable/collapsible bassinet adaptor frame. Here shown is where a front fold frame  36  and a rear fold frame  37  are attached and hinged together with hinge  40  as show in the open position. The hinge  40  is attached to the bottom of the two fold frames  36  and  37 . So when the baby seat carrier  15  is fasten to the top of these frames  36  and  37 , the hinge  40  will not be able to fold, thus locked in this open position. Another version for this bassinet adaptor frame is to be made out of at least two pieces, and to be attached by other standard practice methods. 
         [0052]      FIG. 9B , shows an isometric view of  FIG. 9A  being folded/collapse for less space and easy transport and storage. 
         [0053]      FIG. 9C , shows an isometric view of another possible version of a foldable bassinet adaptor frame. Here shown are two side bars  39 , with pivoting links  38  in between them. When the links  38  are all in line and perpendicular to the side bars  39 , then this frame will be in its open position. When all the links  38  are parallel with the two side bars  39 , then this frame will be in its closed position. 
         [0054]    Please note that here only two different methods of folding this bassinet frame are shown. Many other folding methods could be used, but the concept of a folding/collapsing bassinet frame for easy transport and storage, remains the same. 
         [0055]    While the present invention has been described with reference to the above described preferred embodiments and alternate embodiments, it should be noted that various other embodiments and modifications may be made without departing from the spirit of the invention. Therefore, the embodiments described herein and the drawings appended hereto are merely illustrative of the features of the invention and should not be construed to be the only variants thereof nor limited thereto.
