Description
Background
Many types of swings are available for entertaining infants. Conventional swings for small children generally include a stable, non-moving overhead structure supported by supporting legs. A hanger or hangers are swingably supported relative to the overhead structure and extend downwardly therefrom. The overhead structure can be supported by two rear supporting legs that extend downwardly from the overhead structure and two forward legs which extend downwardly from the overhead structure in a splayed relation, as disclosed for example, in U.S. Pat. Nos. 3,146,985 to Grudoski; 4,271,627 to Echterling; 4,324,432 to Eldon, III et al.; 4,325,578 to Borucki; 4,722,521 to Hyde et al; and 4,785,678 to McGugan et al. These patents generally disclose a pair of hangers attached on either side of a seat, with the upper end of the hangers pivotally or swingably attached to the overhead structure.
Similarly, the swing assembly can have two legs with a single swing arm, as disclosed, for example in U.S. Pat. Nos. 4,805,902 issued to Casagrande; and 4,940,229 to Foster.
U.S. Pat. No. 4,150,820 issued to Bochmann shows an open top swing, without an overhead structure.
A typical problem encountered in all of the above mentioned swings is that when one attempts to put a child into the seat, as the seat is designed to freely swing, the seat swings, making it inconvenient to seat the child. Similarly, when one is taking the child out of the seat, the seat swings with the child making removal also inconvenient. Thus, there is a need for a device to immobilize the seat during removal of a child from or placement of a child into the seat of the swing.
Summary
The present invention is directed to an infant swing having a stabilizer and the stabilizer thereof for use with any conventional swing assembly. The swing assembly for purposes of the present invention can be any conventionally or commercially available swing assembly having any number of supporting leg or legs, a seat, an elongated hanger connected to the seat and swingably connected indirectly or directly to the leg or legs, or to an overhead structure. An infant swing stabilizer according to the present invention has an engaging portion, preferably in the form of a hook, for connecting to or engaging with one of the supporting legs or a member connected thereto, and at least one connector for operatively connecting to the seat or directly to the hanger.
The swing stabilizer according to the present invention is preferably a relatively flat, plate like member. The stabilizer preferably has longitudinally spaced ring connectors for attaching to the hanger. Preferably, the stabilizer is pivotally connected to the hanger so that it can be folded to rest next to the side of the seat during use. The stabilizer according to the present invention can also be completely disconnected from the seat or the hanger and thus from the swing assembly.

Description of the Drawings
FIG. 2 illustrates a partial view of a typical swing assembly 10, with a stabilizer 1 according to the present invention attached thereto. A complete view of the swing assembly is believed to be unnecessary since it is conventional. For purposes of illustrating the present invention, a swing assembly with four legs 12 (only two shown) connected to an overhang structure 14 is chosen. As previously indicated, any conventional swing such as shown in the above-identified prior art patents could be used with the stabilizer according to the present invention.
FIG. 1 shows the stabilizer 1 which comprises a generally flat, plate like member 3 having a hook-like engaging portion 2 and collinearly spaced ring connectors 4 and 5. While the preferred embodiment has a pair of connectors, any number of connectors can be used, including just one, so long as the connector or connectors permit a relatively secure attachment to the seat or the hanger, while permitting the stabilizer to pivot relative to the seat or the hanger. The stabilizer is preferably formed of any durable plastic material, such as polypropylene, polyethylene, nylon, polycarbonates, ABS resins, etc.
The engaging portion 2 preferably is a hook, but for purposes of the present invention, other connectors that permit the stabilizer to be attached to a supporting leg of the swing assembly can be used, such as a string, a strap, a Velcro, etc.
Each of the spaced connectors 4, 5 is preferably formed of an elastic ring type with a slot 4a, 5a, to permit insertion of a circular or tubular member therethrough such as a tubular hanger 16. Due to the elastic action of the ring, the ring stretches to permit insertion of the hanger through the slot and returns to its original shape to retain the stabilizer attached to the hanger.
The unique shape of the stabilizer provides many desirable features. Specifically, the stabilizer is provided with a rounded protrusion 6 extending downwardly in front of the engaging portion opening 8 to prevent the engaging portion 2 from snagging things as the seat swings. The protrusion 6 basically serves as a deflector. The engaging portion 2 which is in a shape of a hook has a soft or rounded contour nose 7 to soften an impact. The nose is also angled .alpha. relative to a line drawn perpendicular to the longitudinal axis 9 of the spaced connectors to permit any item engaged thereto to automatically disengage therefrom when the swing seat is at rest and the stabilizer moved to an inactive position as shown in FIG. 3. While any angle .alpha. can be used so long as the engaging portion can be easily engaged and disengaged, it is preferred to have an angle .alpha. greater than 90.degree., with an angle greater than about 110.degree. being preferred.
FIG. 2 illustrates a swing assembly having four supporting legs 12, stably connected to the overhang structure 14. A pair of elongated hangers 16 are pivotally connected to the overhang structure at one end thereof and fixedly connected at the other end thereof to either side of the seat 18. Thus, the seat can swing relative to the overhang structure.
FIG. 2 is shown with the swing stabilizer of FIG. 1 engaged in an active position, where the stabilizer is connected to a portion of the hanger and to one of the legs to thereby immobilize the seats.
FIG. 3 is a side elevation view of the stabilizer of FIG. 2 in an inactive position, where the stabilizer is disengaged from the leg and pivoted downward and resting next to the side of the seat, allowing the seat to swing. The stabilizer is connected to the hanger with two longitudinally and collinearly spaced ring connectors. In the inactive position, the stabilizer is rotated downward and is resting adjacent the side of the seat, with the engaging portion 2 tucked away so as to not interfere or touch the non-moving elements such as the legs, thus allowing the seat to freely swing. Preferably, the stabilizer should be shorter than the depth of the seat. That is, as more clearly shown in FIG. 4, the nose 7, which is at the lower most point of the stabilizer, preferably should not extend downwardly beyond the bottom 18' of the seat to prevent it from snagging any item when the seat is in motion, i.e., when the stabilizer is in the inactive position.
FIG. 4 is a rear elevational view of FIG. 3 showing the pivotability of the stabilizer to and from inactive to active positions, the active position shown in phantom. In the engaged or active position, the stabilizer is rotated upward so that it is extending laterally, substantially at a horizontal position, with the engaging portion engaged to one of the legs (front right). The engaging portion 2 is spaced laterally from the ring connectors so that the engaging portion automatically engages the leg on the back stroke when pivoted to the active position. It is to be noted that the stabilizer can be attached to the left side in the same manner as described above. In that event, the engaging portion will attach to the front left leg.
In the disengaged position, the stabilizer is substantially positioned parallel to the side of the seat and is unhooked from the leg. This renders the seat fully mobile and the seat free to swing.
In operation, to place a child into the seat, the seat is first moved toward the front, past the front legs. The stabilizer is then pivoted upwards to the active position. The seat can then be moved toward the back to engage the engaging portion to the leg. The child can then be placed into the seat. At this position, removal or placement of a child to/from the seat is convenient since the seat is immobilized from swinging. Furthermore, in the active position the swing is moved forward of the neutral position. As the swing is moved forward, the clearance between the overhang structure and the seat is increased. That is, a child can be placed or removed substantially vertically at this position, making removal and insertion more convenient.
After placing the child into the seat, the seat is again moved forward to disengage the engaging portion and then pivoted downward into the inactive position. The removal steps are substantially the same.
Given the disclosure of the present invention, one versed in the art would readily appreciate the fact that there can be many other embodiments and modifications that are well within the scope and spirit of the disclosure set forth herein, but not specifically depicted and described. Accordingly, all expedient modifications readily attainable by one versed in the art from the disclosure set forth herein that are within the scope and spirit of the present invention are to be included as further embodiments of the present invention. The scope of the present invention accordingly is to be limited to the extent set forth in the appended claims.
