An advanced backpack that converts into a sturdy, potable, student desk via adjustable legs housed on all four sides at the bottom of the Backpack and a HARD desk top surface that can be extended out to create a larger desk top. The backpack will have a 360 degree zipper on compartment #4 of the backpack so the backpack can be completely detached from the base of the Potable Desk backpack if desired. The Backpack will be designed comparable to most Backpack but will separate itself from ALL Backpacks as it can turn into a Potable Desk. Prior designs of backpack stopped at being a housing unit for books and supplies but mine has advanced the backpack by adding adjustable legs on all 4 sides of the bottom of the backpack to enable the backpack to be used as a Potable Desk along with being a housing unit for books and supplies. The Backpack's Potable Desk will be designed so it can be used by a customer standing up or sitting down. The Backpack's Potable Desk surface will be adjustable so it can be extended and/or retracted to create a larger work desk. The backpack will also have a water proof UBS charging port to house two USB charging station and a charging port, a cup holder, an anti-theft device, a pencil holder on the desk and some backpacks will have wheels and a walking handle for travel conveyance.

An advanced Briefcase that converts into a desk via retractable leg and a front, left, and right side walls of the briefcase that folds down to create a desk top surface. This surface can also expand out to create a larger desk top surface. It also has a PORTABLE USB charging station and a cup holder. The portable briefcase will be designed comparable to most Briefcase but will separate it's self from all Briefcases as it can turn into a work desk. Prior designs of Briefcase stopped at being a housing unit for paper work and supplies where mine has advanced the Briefcase by adding adjustable legs on all sides of the bottom of the Briefcase to enable the Briefcase to be used as a work desk and the ability for the front and both sides of the briefcase to fold down to create a desk top surface that can be extended out to create a larger desk to surface along with being a housing unit for paper work and supplies.

A work station including a base includes a work surface pivotally mounted to the base so as to be configured to pivot between a first position and a second position. The work surface is configured to cover a protected member when in a first position and the work surface is configured to uncover the protected member when moved into a second position. The base is configured to support the work surface on a floor surface. A height of the work surface can be adjusted to accommodate the ergonomic needs of different users.

An electric lifting platform retractable upon hitting an obstruction includes a lifting column, a platform, a controller, and a manipulator. The controller comprises a main control unit and a motor driving circuit. An output end of the main control unit is connected to the motor driving circuit. The electric lifting platform further includes a multi-axis sensor module for acquiring obstruction-hitting data of the platform. As the multi-axis sensor module is connected to an input end of the main control unit, the main control unit transmits a control signal to the motor driving circuit after processing the obstruction-hitting data, and the motor driving circuit controls the lifting column to execute a corresponding retracting movement.

A pressure-adjustable gas spring includes a first gas spring and a gas source for adjusting a pressure. One end of the gas source is connected with the first gas spring and another end is connected with an adjustment device for adjusting the volume of the gas source. The adjustment device includes a cavity for accommodating the gas source and a piston. One end of the piston opposite the gas source is connected with a driving subassembly. The driving subassembly includes a screw. One end of the screw is connected with the piston and another end extends out of the cavity. A nut is arranged on the end of the screw extending out of the cavity. A connection tube is arranged outside the nut in a sleeving manner. One end of the connection tube is connected with the cavity and a rotating block is mounted at an opening of another end.

A height adjustable desk includes a work surface, a first telescoping leg, a second telescoping leg, a driving device, and a switch device. The first telescoping leg and the second telescoping leg are connected to the work surface, and are driven by the driving device to lift or low the work surface to any desired height. The switch device is mounted on the first telescoping leg to be activated when the work surface is moved to a predetermined position. The switch device will turn the motor off to stop the work surface when the switch device is activated.
