Description
- 1. Technical Field
- The present invention relates generally to portable desks and, more particularly, to a portable desk for use in vehicles that provides a flat, non-skid, heat-dissipating surface and secures soundly to the front passenger seat of a vehicle.
- 2. Description of Related Art
- Travelers and especially business travelers often find that a need arises to write, use a computer, or perform other office-type functions while in route to or from a destination. This need in particularly acute for those who spend a significant amount of time working in and out of their cars.
- To facilitate these activities, portable desks have been created for use in vehicles. Many different types of portable desks exists-varying in size, material and method of securing the desk into the vehicle. While some of these desks are “universal,” i.e., designed for use in a variety of vehicles, others are designed for use in specific vehicle makes and models.
- Of these “universal” desks, some units are located in the front passenger seat to provide the driver with easy access to items on the desk. These portable desks are designed to rest in the front passenger seat or be secured to the seat itself. Examples of desks such as these are illustrated in U.S. Pat. Nos. 5,092,507; 5,322,021; 5,542,589; 5,551,616; 5,560,676; and U.S. Design Pat. No. 329,444.
- All these patents disclose portable desks that have flat working surfaces. Some desks are designed to store files and hold cups and writing instruments. Other units use a number of straps, or the seatbelt itself, to secure the desk to the front passenger seat.
- Of the portable desks in the prior art, none of them address the need for a simple unit with a non-skid, heat-dissipating surface large enough to hold a laptop computer and a portable printer comfortably, the ability to removably secure the desk to the front passenger seat simply, and the ability to quickly and easily reduce the size of the desk so it can be stored under a vehicle seat or in a briefcase. What is needed is a portable desk that addresses all of these needs.
- The present invention comprises a desktop, a leveling support, and a securing strap. The desktop comprises a base large enough to accommodate a laptop computer and a portable printer wherein the base is covered by a non-skid, heat-dissipating work surface. Both the base of the desktop and the leveling support are made of a lightweight rigid durable material. The top end of the leveling support is perpendicularly attached to the underside of the base of the desktop using a hinging means.
- The securing strap comprises a first strap, a second strap and a locking means. The securing strap is used to secure the desk to the lower portion of a vehicle's front passenger seat. The first and second straps are made of flexible durable strips of material. The locking means, located near one end of the second strap, releasably connects the second strap to the first strap. The other end of the second strap and one end of the first strap are attached to the opposing sides of the leveling support.
- In another embodiment, the desktop comprises a plurality of planar leaves. These planar leaves are foldably attached to one another allowing the desktop to be collapsed for storage underneath a vehicle's seat or in a briefcase. In order to create a stable, sturdy surface when the desktop is extended, bracketing means are used to support the inner facing edges of the leaves by traversing these edges.
- The primary advantage of this invention is that it provides the business traveler with a simple portable desk that contains a large, non-skid, heat-dissipating work surface, an easy method of securing the desk to a vehicle's front passenger seat, and the option of a collapsible desktop that facilitates storage or movement of the desk.
