Abstract

An assembly composing of a robust articulating armature with optionally interchangeable platform like components which incorporate and adapts the core armature assembly into a multitude of product configurations each having ergonomic benefits. The core articulating armature is configured to be a variably lift assisted and repositionable in a manner when combined with the other elements, configures to become a device with demonstrably beneficial features in each of its configurations. In some of the configurations, lift assistance and positional support is the primary feature, whereas in other configurations, flexing and returning back to a user designated set position becomes the primary feature. This application discloses a device with the flexibility to be configured in such a manner as to bring benefits to both the consumer and to the manufacture due to its uniquely modular and configurable elements which can be utilized to create a multitude of ergonomic product configurations.

First claim

1 . A support device for selectively elevating a platform above a working surface, the device including:
a base for resting on a work surface; an articulating armature assembly; and a platform assembly, the base coupled to the articulating armature assembly, and the articulating armature assembly coupled to the platform assembly, the articulating armature assembly having a range of elevation to selectively raise and lower the platform assembly above the working surface, the elevation being selected by the user through an articulation actuator, the articulation actuator including a spring.

2 . The device of claim 1 , wherein the articulation actuator includes an actuation lever to selectively engage the spring.

3 . The device of claim 2 , wherein the spring provides a counterforce to a downward force on the platform assembly when the articulating armature assembly is in an upper range of elevation.

4 . The device of claim 1 , further including a second spring, the second spring having a force higher than the first spring.

5 . The device of claim 4 , where in the first spring provides force to the articulating armature assembly in a first range of elevation, and the second spring provides force to the articulating armature assembly in a second range of elevation.

6 . The device of claim 5 wherein a first actuation lever selectively engages the first spring, and a second lever selectively engages the second spring.

7 . The device of claim 2 further including a range controller, the range controller defining the range in which the articulating armature assembly moves.

8 . The device of claim 7 , wherein the spring provides counterforce to a downward force on the platform assembly, when the armature assembly moves within the range defined by the range controller.

9 . A support device for elevating a platform above a work surface, the device including:
a base; an articulating armature assembly; and a platform assembly, the base coupled to the articulating armature assembly, and the articulating armature assembly coupled to the platform assembly, the articulating armature assembly having range of elevation above the base, a spring engaged with the articulating armature assembly to provide a counterforce to a downward force on the platform assembly.

10 . The device of claim 9 , wherein the spring engages with a range controller to limit the range of elevation.

11 . The device of claim 9 wherein the counterforce supplied by the spring is selectively engaged by an actuation lever.

12 . The device of claim 9 further including a slide plate on the bottom of the base, the slide plate selectively in contact with a surface upon which the base rests when the base is tilted by the user, the slide plate not being in contact with the surface when the base is not tilted.

13 . The device of claim 9 further including a second spring to provide a counterforce to a downward force on the platform assembly, the second spring applying its downward force when the articulating armature assembly is in a second range of elevation above the base.

14 . The device of claim 13 where the second range of elevation is limited by a second range controller.

15 . The device of claim 1 , wherein the device includes a rotational bearing allowing the articulating armature assembly to rotate with respect to the base.

16 . The device of claim 1 , wherein the articulating armature assembly is a four bar assembly.

17 . A support device for elevating a platform above a working surface, the device including:
a base assembly for resting on the working surface; an articulating armature assembly coupled to the base assembly; and a platform assembly coupled to the articulating armature assembly, the articulating armature assembly having a range of elevation positions, a biasing member engaged with the articulating armature assembly, the biasing member providing a counterforce against a downward force on the platform assembly when the articulating armature assembly is at an elevation higher than a lower elevation position, and a range controller engaged with the biasing member to limit the range of elevation positions in which the biasing member applies the counterforce.

18 . The device of claim 17 , where the biasing member is a gas strut.

19 . The device of claim 17 , further including the articulating armature assembly having a second range of elevation position, the second range being higher than the first range, a second biasing member engaging the articulating armature assembly and providing a second counterforce against the downward force on the platform assembly, and a second range controller engaged with the biasing member to limit the second range of elevation positions in which the biasing member applies the second counterforce.

20 . The device of claim 19 further including a TPU grommet between the base assembly and the articulating armature assembly.
