BACKGROUND OF THE INVENTION
Field of the Invention

The present invention generally relates to an improved adaptable workstation and more specifically to more efficient movement of work stations when loaded or unloaded and/or improved storage and utility functions for adaptable work stations including work benches and desk areas.

Background Information

Sit stand desks are not new. Even push-button, self-rising desks are not new. First generation sit stand desks leave a lot to be desired. The drawbacks of the current sit-stand type work stations is that there are issues of raising and lowering the stations quietly and/or efficiently when in either a loaded or unloaded state. Additionally, the current sit stand workstations have generally low load limits or are limited in design possibilities for the end user. The present state of sit-stand work stations is very uniform with very little options for the end user in regards to leg placement, cord placement, desk design and storage capabilities.

Unfortunately sit stand work stations, despite their known health benefits, have been slow to be incorporated into the general work population, the reasoning seems to be that users have not been able to find that the increased technology is efficiently applied and customizable for each users end workstation set-up.

The embodiments of the present invention generally include improvements in motor efficiencies and more customizable workstation design options which solve the above described problems. Thus, the embodiments of the present invention provide for an improved adaptable sit stand workstation.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention are based on the desire to make an improved adaptable sit stand workstation. The embodied invention achieves this through integrating a plurality of features selected from a better motor liner actuator design, for two legged or four legged workstations; customizable storage management and accessory management features; and/or smart technologies for more efficiently managing either the workstation, the user, and or the users equipment and personal items.

Improved Motor Embodiments

Embodiments of the present invention relate to an improved motor system comprising a new type of motor and decelerator structure design of a liner actuator further including a floating motor assembly/decelerator without a frame.

The Liner Actuator (linear driver, lifting column, etc.) is an extension of the structure of the rotating motor. It is an electric drive that converts the rotational motion of the motor into a straight reciprocating motion of the push rod. The embodied Liner Actuator can be used in a variety of simple or complex processes as the implementation of mechanical use, in order to achieve long-range control, centralized control or automatic control. Can achieve long-range centralized or automatic control. The liner actuator comprises a drive motor, reduction gear, screw, nut, guide sleeve, putter, slide, spring, shell and turbine, micro control switch and other components.

At present, in order to ensure efficiency, the motors and speed decelerators of the prior art need high-precision fixed installation to ensure concentricity, thus, the decelerator also needs a high-precision frame to ensure the operation of the concentricity. When the operation of the concentricity fails the unit falls off track or high degrees of wobble or is unable to move efficiently when loaded. Furthermore the disadvantages of this fixed high precision from design is: 1) space occupied, the entire liner actuator's trip is limited; 2) Expensive, the complexity structure and high precision assembly requirement means a higher cost of the components and assembly.

The embodied new type of motor and decelerator design for liner actuator, is designed to be a Floating Motor Assembly and a No Frame Decelerator Assembly. The floating motor assembly comprises a motor base, an elastic parts and fastener, The No Frame Decelerator assembly comprises a sun gear, planetary gear and outer ring driving gear wheel.

There is an elastic parts (spring or other resilient part) between the motor and the fastener fixed to the motor base, in the process of running in a limited floating state, the motor shaft drives the sun gear, the sun gear drives the planetary gear, the planetary gear drives the Ring drive gear wheel, ring drive gear wheel directly or through the coupling indirect drives the screw mechanism.

Due to the use of the floating structure, the entire drive and Decelerator need not maintain a tight centimeter structure, and a fixed frame can be omitted. The entire drive mechanism can be automatic and maintains the concentricity itself during the operation. The core of this design is to use a more simple structure to solve the concentricity, it additionally maximizes the motor's driving force, and reduces the efficiency loss and vibration by the normal high rigidity transmission mechanism design. Additionally, the embodied liner actuators self-adaptation feature can effectively eliminate problems caused by external structures and parts defect, like poor screw straightness, external structure offset etc.

Some of the advantages of the embodied liner actuators are that they greatly reduce the mechanism space at the direction of the linear drive, which improves the effective working stroke, as compared with other designs using a similar motor and gear-reduction ratio but a fixed frame assembly.

Second, the present embodiments reduce the complexity of the lifting mechanism, by reducing the manufacturing difficulty and cost. As the decelerator mechanism no longer requires a fixed frame, the assembly complexity is greatly reduced, the manufacturing difficulty is greatly reduced, and the number of parts and parts processing accuracy requirements is greatly reduced.

An embodied liner actuator mechanism 00 is depicted in FIG. 1 wherein FIG. 1 is a schematic diagram of this new type of motor and decelerator design of the embodied Liner actuator 00. As label indicated: 1, screw; 2, bearing; 3, coupling; 4, outer ring driving gear wheel; 5, planetary gear; 6, shock absorber washer; 7, planetary gear carrier; 8, motor; 9, fastener; 10, compression spring or other elastic parts; 11, sun gear; 12, Motor support; 13, coupling elastomer.

The motor floating support structure 00 is mainly completed by the Coupling Elastomer 13 and the shock absorbing washer 6 and the compression spring 10; The driving structure is composed of the outer ring driving gear wheel 4, the planetary gear 5, the planetary gear carrier 7, the motor 8 and the sun gear 11, the screw 1 and the bearing 2.

During the liner actuator's operation, at the push rod working direction, if the eccentricity happens (caused by assembly, or screw 1 poor straightness, or by the external structure offset), the partial load force from the eccentricity can cause the motor to slightly move within the floating fixing mechanism, and maintain the mechanism in a centralized position. It is a form of a self-correcting mechanism.

In the embodied structure, the material, size and shape of all components can be adjusted as needed. For example the fastener 9, the compression spring 10 can be replaced by other structural components or processes, such as replacing the compression spring 10 with other similar elastomers, or replacing the fastener 9 with pins or other fixed parts, which can achieve the same floating motor fixing structure.

The screw 1 and the bearing 2 and the motor support 12 constitute a push mechanism which is a universal screw drive-type mechanism, which can be used in virtually any other screw drive type structure as well.

In the present embodiments the liner actuator is used in workstation legs to raise and lower the station.

As shown in FIG. 2 an embodied liner actuator 00 is placed in the leg 22 of an embodied sit stand work station (not shown). The screw 1 and sun gear 11 of the liner actuator 00 are shown in the column of the leg. The liner actuator engages the height adjustable desk column. The column is may be about 680 MM in the shortest length, with only one screw lever inside required inside but can achieve about a 520 MM straight line travel to reach 1200 MM at its longest length, and does not require a frame structure for the decelerator to be secured to within the leg.
