A table elevating device includes: a table, formed with a bottom surface, a first side edge and a second side edge spaced away from the first side edge; a support mechanism, vertically disposed for supporting the table, and at least including an electric pushing rod used for driving the support mechanism to be elevated; a driver, served to drive the electric pushing rod to be operated via electric power; and a controller, including a case body having a first case part and a second case part and disposed on the bottom surface, and a control circuit unit electrically connected to the driver; wherein, the second case part is formed with an expansion hole oriented to face the second side edge along an extending direction defined from the interior towards the exterior.

An apparatus for adjusting the assistive lifting force capacity of a height adjustable work surface. The apparatus includes a couple of plates which are mounted to a system for providing a system for adjusting the height of the work surface. The plates include a set of connection points for connecting the apparatus to a gas spring. The geometry of the holes and the positioning of the gas spring provide for a more consistent lifting force throughout a range of motion of the work surface.

A height adjustment mechanism is provided. The height adjustment mechanism includes a lifting arm, a driving mechanism configured to drive and lock the lifting arm, and a control switch configured to control the driving mechanism; the driving mechanism is coupled to the lifting arm, and an angle is formed between the driving mechanism and the lifting arm. A height adjustment platform and method is also provided. The height adjustment platform includes a first working table, a bottom bracket, a lifting arm, a driving mechanism configured to drive and lock the lifting arm, and a control switch configured to control the driving mechanism; two opposite ends of the lifting arms are separately coupled to the first working table and the bottom bracket, the driving mechanism is coupled to the lifting arm, and the angle is formed between the driving mechanism and the lifting arm.

A table elevating device includes: a table, formed with a bottom surface, a first side edge and a second side edge spaced away from the first side edge; a support mechanism, vertically disposed for supporting the table, and at least including an electric pushing rod used for driving the support mechanism to be elevated; a driver, served to drive the electric pushing rod to be operated via electric power; and a controller, including a case body having a first case part and a second case part and disposed on the bottom surface, and a control circuit unit electrically connected to the driver; wherein, the second case part is formed with an expansion hole oriented to face the second side edge along an extending direction defined from the interior towards the exterior.

A lifting mechanism for desk including a first bracket, a second bracket, and at least one lever assembly is provided. The first bracket includes a first plane. The second bracket includes a second plane. The lever assembly is connected between the first bracket and the second bracket so that the first bracket moves close to or moves away from the second bracket through the lever assembly, and the first plane is tilted relative to the second plane when the first bracket is away from the second bracket. The lever assembly includes at least two levers, and lengths of the at least two levers are different.

An adjustable height platform is disclosed. The example adjustable height platform provides a first stage of uprights coupled to a lower platform and a second stage of uprights coupled to a lower platform. The first and second stage are coupled by a bracket with three pivot points. A first lower upright and a first upper upright couple to distinct pivot points on the bracket and a second lower upright and second upper upright couple to a common pivot point on the bracket. A first-to-second stage transfer mechanism transfer rotation force from the first stage of uprights to the second stage of uprights. The upper platform includes a height fixing mechanism release to interface with a height fixing mechanism coupled to the first upper upright to fix the height of the adjustable height platform.

An item of furniture having a lift-top working surface configured to elevate a part of the furniture above other, similar components. This lifting functionality is configured so that the item is usable in a variety of human ergonomic positions, such as seated and standing. Typically, the furniture is a desk, and the lift-top surface elevates a portion of the desktop from a seated to standing position using a lift mechanism or lift means hidden within a compartment of the desk body during non-use. The compartment may double as a storage, such as for cables, wires, and other typical office equipment.

An adjustable desk platform can include: an upper platform defining a substantially planar work surface; a base located beneath the upper platform, the base defining a bottom surface without legs that is adapted to sit on an existing desk; first and second sets of arms coupling the upper platform to the base, wherein the first and second sets of arms are adapted for movement of the upper platform substantially in parallel with the base between a fully raised position and a fully lowered position; and a user-operable locking mechanism associated with the upper platform, the locking mechanism adapted to releasably lock the upper platform in the fully raised position, and in at least one intermediate position between the fully raised position and the fully lowered position. Other features and embodiments are discussed.

A desktop liftable platform has a base, a supporting frame, a platform, and a driving device. The base has two side beams and a connecting beam connected to rear ends of the side beams. The supporting frame is connected to the base and has two pivot anus connected to the side beams adjacent to front ends of the side beams. The platform is connected to the pivot arms over the base. The driving device is connected to the base and the supporting frame and has a driving motor, two slide groups, and two swing arms. The driving motor is deposited on the base. The slide groups are connected to and are driven by the driving motor. The swing arms are connected to the pivot arms and the slide groups, and are rotated relative to the base by the driving motor to enable the platform to move relative to the base.
