DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) Illustrative embodiments of the invention are described below. The following explanation provides specific details for a thorough understanding of and enabling description for these embodiments. One skilled in the art will understand that the invention may be practiced without such details. In other instances, well-known structures and functions have not been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

(9) Unless the context clearly requires otherwise, throughout the description and the claims, the words comprise, comprising, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of including, but not limited to. Words using the singular or plural number also include the plural or singular number respectively. Additionally, the words herein, above, below and words of similar import, when used in this application, shall refer to this application as a whole and not to any particular portions of this application. When the claims use the word or in reference to a list of two or more items, that word covers all of the following interpretations of the word: any of the items in the list, all of the items in the list and any combination of the items in the list. When the word each is used to refer to an element that was previously introduced as being at least one in number, the word each does not necessarily imply a plurality of the elements, but can also mean a singular element.

(10) FIGS. 1A, 1B and 2 illustrate a baby seat 10 for attaching to a table 20 that has a top surface 28, a side edge 25, and a bottom surface 22. The word table herein is broadly defined as any suitably rigid surface, such as a countertop, desk, or other support structure, that has the side edge 25, the top surface 28, and the bottom surface 22.

(11) The baby seat 10 includes a U-shaped support frame 30 (FIG. 1B) that has two opposing arms 35, each that is connected with a lower support surface 40 that is itself adapted for contacting the top surface 28 of the table 20. The lower support surface 40 may be formed as part of the U-shaped support frame 30 (not shown), or may include a separate piece that is connected with one of the arms 35 of the U-shaped support frame 30, typically with a mechanical fastener or simply a friction-fit. Such a lower support surface 40 is made from a rigid, strong material, such as plastic, metal, wood, or the like, and may include a resilient material that is preferably an elastomeric or rubber material where contacting the top surface 28 of the table 20. The U-shaped support frame 30 is preferably made with metallic tubes or other suitably rigid materials.

(12) A flexible seat 50 is adapted for fixing at least partially over the U-shaped support frame and being suspended thereby. The flexible seat 50 includes a U-shaped cover 51, a seat bottom 52, and a front cover 53 that has two leg apertures 54 therethrough. The flexible seat 50, when suspended from the U-shaped support frame 30, assumes an expanded configuration 59 (FIGS. 1A and 2). When compressed the flexible seat 50 assumes a collapsed configuration 58 (FIG. 4), a useful configuration for storage and transport of the baby seat 10. A U-shaped channel 55 at a top portion 57 of the flexible seat 50 is adapted for friction fitting around the Us-shaped support frame (FIG. 1A). Alternately, or additionally, the flexible seat 50 is fixed with the U-shaped support frame 30 with mechanical fasteners 56. The flexible seat 50 is preferably made with an easy-to-clean flexible silicon rubber material.

(13) A clamping mechanism 60 is fixed with each of the two opposing arms 35 of the U-shaped support frame 30. The clamping mechanism 60 includes a lower clamping arm having a top surface 63 adapted for contacting the bottom surface 22 of the table 20. Such a top surface 63 may include a resilient material 100 that is preferably an elastomeric or rubber material 101. The clamping mechanism 60 may further include a lever arrangement 65 and an actuator arm 67 that projects rearwardly away from the front cover 53 of the flexible seat 50. The actuator arm 67 is movable between an open position 69 (FIG. 5) and a clamped position 68 (FIG. 2). Preferably each actuator arm 67 is mutually connected to form a U-shaped actuator arm 66 (FIG. 1B). In such an embodiment, the U-shaped actuator arm 66 preferably includes an elastomeric grip 110 at an apex 64 of the U-shaped actuator arm 66.

(14) As such, with each actuator arm 67 of the clamping mechanisms 60 in the open position 69, and with the lower support surface 40 of each arm 35 of the U-shaped support frame resting on the top surface 28 of the table 20 proximate the side edge 25 of the table 20, and with the top surface 63 of the lower clamping arm 62 below the bottom surface 22 of the table 20, each actuator arm 67 of the clamping mechanisms 60 can be moved to the clamped position 68 to clamp the table 20 between the lower support surface 40 of each arm 35 and the top surfaces 63 of the lower clamping arms 62.

(15) The clamping mechanism 60 may include a clamping force adjustment mechanism 70 such that a clamping force across a gap 75 formed between the lower support surface 40 of each arm 35 of the U-shaped support frame 30, and the top surface 63 of the lower clamping arm 62, when the actuator arm 67 is moved from the open position 69 towards the clamped position 68, is selectively and manually adjustable. Alternately the clamping mechanism 60 automatically adjusts to provide an adequate clamping force to the table 20, even with a wide variety of table thicknesses.

(16) In one such embodiment, the lever arrangement 65 of each clamping mechanism 60 further includes a clamping base 120 (FIG. 3) fixed with one of the arms 35 of the U-shaped support frame 30. An actuator arm receiver 130 receives the actuator arm 67 and is pivotally attached with the base 120 through a linkage 140 at a first pivot point 150. The actuator arm receiver 130 is also pivotally attached with the lower clamping arm 62 at a second pivot point 160, and with a spring-biased tensioner 180 at a third pivot point 170. As the actuator arm 67 is moved into the open position 69, the linkage 140 is pulled away from the clamping base 120 until the spring-biased tensioner 180 further pushes the linkage 140 away from the clamping base 120. This allows the lower clamping arm 62 to pivot away from the table 20. Conversely, when the actuator arm 67 is moved towards the clamped position 68, the lower clamping arm 62 stops pivoting when the top surface 63 thereof contacts the bottom surface 22 of the table 20. The linkage 140 thereafter is pressed upward toward the clamping base 120 by the actuator arm receiver 130, pressing against the spring-biased tensioner 180 until it passes directly between the first pivot point 150 and the third pivot point 170. Thereafter the spring-biased tensioner 180 pushes against the linkage 140 to maintain it against the clamping base 120. The clamping mechanism 60 firmly holds the baby seat 10 to the table 20 between the top surface 63 of the lower clamping arm 62, and the lower support surface 40 of each arm 35 of the U-shaped support frame 30.

(17) Preferably the actuator arm 67 includes a lever lock 190 (FIG. 1B) that prevents the actuator arm 67 from moving to the open position 69 from the clamped position 68 unless actuated. Such a lever lock 190 may have a lock linkage (not shown) internal to the U-shaped actuator arm 66 that locks the clamping mechanism 60 in place unless withdrawn by actuating the lever lock 190. Alternately, manual catches 195 may be included that prevent the actuator arm 67 from moving to the open position 69 from the clamped position 68 unless the manual catches 195 are manually pressed out of the way.

(18) In a simplified embodiment of the invention, illustrated in FIG. 6, the lower clamping arm 62 includes a J-shaped arm 200 terminating at an adjustable barrel 210 having the top surface 63, the adjustable barrel 210 having an internal screw thread 215 cooperative with an outer thread 205 of the J-shaped arm 200, whereby the adjustable barrel 210 can be turned until the top surface 63 contacts the bottom surface 22 of the table 20.
