An advanced laptop Bag that can converts into a portable work desk via extendable and adjustable legs housed on all 4 sides at the bottom of the laptop bag so it can turn into a sturdy work desk and has a waterproof PORTABLE USB charging station, anti-theft unit, and a cup holder. The Portable Desk Laptop Bag will be designed comparable to most Laptop Bag but will separate itself from all Laptop Bags as it can turn into a work desk. Prior designs of Laptop Bag stopped at being a housing unit for laptops and supplies where mine has advanced the Laptop Bag by adding adjustable legs at all sides of the bottom of the Laptop Bag to enable the Laptop Bag to be used as a work desk for the laptop while also being a housing unit for the laptop and supplies.

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.

The present invention relates to a bag usable as knee guards and, more specifically, to a bag usable as knee guards, which can retain heat or prevent damage to knees by surrounding the knees according to the needs of a user and can also be used as a bag. The subject matter of the present invention is a bag usable as knee guards, comprising: a first body which has one side open so as to form an accommodating space therein and surrounds a knee of a user with the knee bent; a second body which is formed so as to correspond to the first body and surrounds the other knee of the user with the knee bent; and a coupling means for coupling the open parts of the first and second bodies so as to form a bag shape, wherein: the first body has a cut part which can be opened and closed by a locking mechanism, and a storage pocket is formed inside the first body so as to communicate with the cut part, so that an article can be stored in the storage pocket by the locking mechanism even if the first and second bodies are uncoupled; each of the first and second bodies has connecting means for fixation formed at either end thereof so as to prevent detachment after being wrapped around the knees of the user; and the cross sections of the respective first and second bodies are in a triangular shape, so that the cross sections form a square shape when the first and second bodies are coupled to one another.

A binder device including a body having a first cover and a second cover directly or indirectly pivotally coupled together and at least partially defining an inner compartment therebetween. The body further includes a binding mechanism positioned in the inner compartment, a first body securing device coupled to the body, and a second body securing device coupled to the body. The binder device includes a strap including first and second strap segments. The strap is movable between a first configuration wherein the first and second strap segments are releasably coupled together to form a continuous strap that is wearable over a shoulder of a user, and a second configuration wherein the first strap segment is releasably coupled the first body securing device and the second strap segment is releasably coupled to the second body securing device such that the first and second strap segments each at least partially defines a loop. Each loop is shaped and configured to receive an arm of a user therethrough such that the binder device is wearable on a back of the user in the manner of a backpack. Each strap segment is configured to be releasably coupled to only one of the first or second body securing devices.
