The present invention relates to to a children's high chair that incorporates a horizontal swivel feature with 3 lockable positions for the child's seat.

High chairs have seats which are typically elevated above a floor to a level that is convenient for an adult to feed the child from the adult's sitting position. Most high chairs have a fixed seat that is oriented in a forward-facing direction of the high chair. When the high chair is situated on a floor surface, the seat position is forward facing at all times. It is sometimes desirable to re-orient the direction in which the child and high chair seat face. To re-orient the seat so that it faces in a different direction, the entire high chair must be rotated relative to the floor surface. Repositioning the high chair with a child in it is heavy and can cause dangerous situations. Swiveling the seat of the high chair on a fixed base is much more convenient and safe.

This invention provides a high chair that will integrate a swivel function.

This invention provides a swivel lock mechanism for a children's high chair that will provide 3 seat positions; straight towards a table, 90° clockwise or 90° counterclockwise relative to the table.

It is an advantage of this invention that the actuation latch can be actuated from the back side of the high chair because this side is always pointing away from the table, therefore easy to remember, find, reach and use.

It is an advantage of this invention that the actuation latch unlocks the fixed positions by pulling backwards before rotating the seat shell.

It is a feature of this invention that the actuation latch has a stop member that is engagable with recesses in a guiding track integrated in the upper cover lid of the swivel mechanism.

It is an advantage of this invention that the actuation latch automatically locks into 1 of the 3 fixed positions by engaging the spring-loaded stop member into one of the recesses in the guiding track.

It is an advantage of this invention that the sound of the automatic spring-loaded engagement of the swivel lock indicates that the seat shell is safely locked into 1 of the 3 seat positions.

It is an advantage of this invention that the spring-loaded actuation latch prevents the seat from becoming a free rotating seat.

These features and advantages are accomplished according to the invention by providing a high chair that has a swivel function that permits the seat shell to be positioned to the convenience of the user. The high chair includes a swivel device which is assembled between the high chair base and seat shell and that provides the seat shell to swivel relative to the base in both directions. A swivel lock includes an actuation latch with a handle positioned on the rear of the base for actuation from the rear side of the high chair, which is the opposite side of the footrest. The actuation latch includes a spring-loaded stop member that is engagable with 3 recesses in a guiding track integrated into the upper cover lid. To secure the rotated position of the seat, the spring-loaded stop member engages 1 of the 3 recesses in the guiding track.

The foregoing and other objects, features, and advantages of the invention will be apparent from the following more particular description of a preferential form of an embodiments of the invention, as illustrated in the accompanying drawings, given as a non-restrictive example.

It will be appreciated that for simplicity and clarity of illustration, where considered appropriate, numerous specific details are set forth in order to provide a thorough understanding of the exemplary embodiments described herein. The present invention now is described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. However, it will be understood by those of ordinary skill in the art that the embodiments described herein may be practiced without these specific details. Indeed, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

In other instances, well-known methods, procedures and components have not been described in detail so as not to obscure the embodiments described herein.

The present application uses the term "swivel" as it is conventionally used and understood by those practiced in the art of mechanics.

In the claims as set forth hereinafter, the word "comprising" does not exclude other elements or steps, and the indefinite article "a" or "an" does not exclude a plurality.

The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures can not be used to advantage.

Referring to the drawings in FIG. 3 and FIG. 4, a child high chair incorporating the principles of the invention can best be seen. The high chair 10 consists of a base 20 and seat shell 60. In between is the swivel lock device 30 which connects base 20 and seat shell 60. The swivel lock device 30 can be divided into a fixed bottom cover lid 40 and a swiveling upper cover lid 50. The fixed bottom cover lid 40 is mounted beneath the cross mounted brackets 21+22 of the base 20. On top of the cross mounted brackets 21+22, a turntable bearing 42 is mounted with standoff washers 41 between brackets and bearing. The turntable bearing 42 consists of an inner ring 421 and an outer ring 422. The inner ring 421 will be the fixed member and the outer ring 422 will be the rotating member. The inner ring 421 of the bearing 42 is fixed to the bottom cover lid 40 with 4 bolts 43 which go through the assembly holes of the cross mounted brackets 21+22.

The swiveling upper cover lid 50 is assembled between mounting plate 51 and seat shell 60 with 4 bolts 52. The mounting plate is connected to the outer ring 422 of the turntable bearing 42 with 4 bolts 53.

The bottom cover lid 40 houses a latch with integrated stop member member 44 which is spring loaded with 2 springs 45 and kept in place by cover plate 46 and 2 screws 47. The upper cover lid 50 has a guiding track with 3 recesses in which the stop member member of the latch 44 is engaging.

FIG. 5 is an cross sectional top view of the swivel lock mechanism when the seat shell is pointed straight forward. The black hatched section is the guiding track of the swiveling upper cover lid 50. The stop member of the latch 44 is engaged in the right recess of the guiding track.

FIG. 6 is an cross sectional top view of the swivel lock mechanism when the seat shell is unlocked and swivels freely between 2 positions. The black hatched section is the guiding track of the swiveling upper cover lid 50. The concave shaped stop member of the spring-loaded latch 44 is pushing against the guiding track of the upper cover lid 50. Once a recess is in front of the stop member, the stop member jumps into the recess and locks the upper cover lid 50. To unlock the position the user should pull the latch 44 backwards out of the recess and rotate the seat shell 60 of the high chair. The handle of the latch 44 will stay in pulled out position till the latch engages the next position.
