The grip 132 can be coupled to a latch member 134 (see FIGS. 2 and 7) adapted to engage the pinion 130, for example, the grip 132 can be coupled to the latch member via a link member 136 134, the link member 136 can move a portion of the latch member 134 in a horizontal direction and mesh with the pinion gear 130. According to an embodiment, the grip 132 can be pivotally mounted to the lower surface 106 of the platform 102 by opposing pairs of pivoting blocks 133, however other configurations are possible.

According to an embodiment, the latching member 134 can be biased into engagement with the pinion gear 130 such that the latching member 134 normally secures the pinion gear 130. Thus, in the event that the user does not disengage the latch mechanism, the latch mechanism will lock the rack and pinion system 120 and substantially secure the first and second legs 108, 110. According to an embodiment, a spring or other resilient member associated with the latch housing 138 can bias the latch member 134 into engagement with the pinion 130, however other configurations are possible. Additionally or alternatively, the spring or other resilient member associated with the grip 132 can bias the latch member 134 into engagement with the pinion 130. When a user desires to change the position of the first and second legs 108, 110, the user can pivot the handle 132, which in turn causes the latch member 134 to disengage the pinion 130, thereby allowing the user Move the lift table 100 to the desired height. The release grip 132 re-engages the latch member 134 with the pinion 130, thereby securing the pinion 130 and substantially locking the position of the first and second legs 108, 110 relative to the platform 102. As best seen in Figures 2, 3 and 6, the lift table 100 can include a first latch mechanism and a second latch mechanism, both of which can be substantially as described above. Accordingly, the user may need to disengage both the first and second latching mechanisms to change the position of the first and second legs 108, 110 relative to the platform 102, however, other configurations are possible.

Still referring to Figures 7 and 8, one or more resilient members 140, such as spring or elastomeric devices, may be provided to preload or bias the first and second legs 108, 110 relative to the platform 102. For example, in the illustrated embodiment, one of the resilient members 140 can be anchored to the second rack 124 at one end and the lower surface 106 of the platform 102 at the opposite end. The resilient member 140 can be positioned such that moving the leg 110 from the fully raised position toward the fully lowered position can cause the resilient member 140 to stretch, thereby providing resistance to such reduced direction motion. Moreover, moving the foot 110 from the fully lowered position toward the fully raised position may cause the resilient member 140 to relax, thereby providing a lift assist, which facilitates moving the lift table 100 toward the raised position. As shown in Figures 7 and 8, another resilient member 140 can be provided to connect the first leg 108 to the first rack 122. On the lower surface 106 of the platform 102, in the vicinity of the elastic member 140 Several recesses may be provided, for example to provide sufficient clearance, however, other configurations are also possible. The talkative component 140 is not limited to the configuration shown, and rather, other configurations are possible, as will be appreciated by those of ordinary skill in the art based on the present disclosure.

Referring collectively to Figures 1 and 6, the height of the lift table 100 can be adjusted by the user to suit his or her needs or circumstances. For example, Figure 6 reveals that the lift table 100 is in a fully lowered position. By pivoting the grip 132, the user can disengage the latch mechanism from the rack and pinion system 120, such as under the "elevation aid" provided by the optional resilient member 140, The first and second legs 108, 110 are allowed to rise relative to the platform 102. The user can then move the platform 102 to one of the intermediate positions, or to the fully raised position, and release the grip 132 to re-engage the latch mechanism and the rack with the pinion system 120. Thereby the first and second legs 108, 110 are substantially locked in position. Figure 1 reveals that the lift table 100 is in a fully raised position. After use, or when a change in position is desired, the user can pivot the grip 132 again, disengaging the rack and pinion system 120 to move the platform 102 to the desired position. In the case of storage, the user can move the platform 102 to the fully lowered position shown in Figure 6, thereby providing a compact form for storage or for use while sitting. The action of the platform 102 from a fully raised position toward a fully lowered position can stretch the resilient member 140 to provide a damping effect to the lowering action.
