component of the support frame 108 that is generally parallel to the floor table legs not illustrated may be coupled to the illustrated support frame 108 component to support the tabletop 112 as is known in the art as mentioned above the tabletop mechanism 104 permits the tabletop 112 to be secured in two positions relative the support frame 108 often one position secures the tabletop 112 in a generally horizontal orientation and the other position secures the tabletop 112 in a generally vertical orientation in other embodiments however the mechanism 104 may secure the tabletop 112 in an inclined position and a vertical position for instance in the inclined position the mechanism 104 may secure the tabletop 112 at an approximately forty five degree angle relative a plane parallel to the floor as is commonly done with drafting tables and the like for simplicity the mechanism 104 is described herein as securing a tabletop 112 in a horizontal and a vertical position although it is understood that the mechanism 104 may secure the tabletop 112 in two positions of an angular orientation it is noted that the tabletop mechanism 104 is shown secured to the bottom surface of the tabletop 112 in fig1 3 the bracket 116 may be connected to the tabletop 112 as shown in fig1 3 however in other embodiments the bracket 116 may be connected to the support frame 108 the bracket 116 includes a pair of flanges 124 and a base region 128 as shown in fig4 and 5 the flanges 124 may extend from the base region 128 at an angle approximately perpendicular to the base region 128 at least a portion of the first and second lock elements are coupled to the bracket 116 a top.
