Portable, compacting travel footrest
A footrest for airplane passengers includes a platform and a number of supporting legs, at least some of which contain springs or resilient members so that when the legs are deployed the passenger can exercise his feet and legs by pressing down on the platform. The legs can be folded or otherwise collapsed against the platform when the device is not in use.
This application claims benefit of U.S. application No. 60/598848, filed Aug. 5, 2004.
BACKGROUND OF THE INVENTIONAn average aircraft seat is only 17 inches wide and has only about 32 inches of “pitch” or distance between the back of the seat facing the passenger and the back of the seat in which the passenger is seated. Such cramped configuration has concerned travelers and health practitioners alike. An estimated 30,000 people a year could develop dangerous lower leg blood clots, commonly referred to as “economy class syndrome,” as a result of sitting in cramped conditions for more than five hours.
To avoid “economy class syndrome,” health specialists suggest exercising the legs. Such may be achieved with, for example, an exercise footrest. However, while redesigns may be possible, airline seats have been largely unchanged for the last 25 years due to elaborate safety certification processes related to issues and costs. Thus, redesigning airline passenger seating to allow for more leg room and include health-safety features, such as footrests, is not foreseeable. While comforts and luxuries are increasingly available for first- and premium-class passengers, economy class passengers are likely to be left with the cramped spaces that are not only uncomfortable but also can pose serious health hazards.
Additionally, as technology pervades home and work lives, people increasingly travel with laptops and other devices that they operate from their “laps” at airports, rail stations, make-shift offices, homes etc. Sitting in a chair for long periods of time can cause back and other problems. These problems may be avoided, but at considerable expense or encumbrance.
What is needed is a portable footrest that helps alleviate pressure on the lower back by raising the level of the knees to reduce back strain, muscle fatigue and injury, and to allow for better circulation of blood in the lower legs. While such may not be a “medical solution” and does not guarantee prevention against potential health hazards from traveling in cramped positions, it is widely regarded as a practical solution by medical practitioners and health experts alike because a portable footrest can help prevent and/or reduce back and lower leg conditions, including stress injuries and blood clots in the lower legs, that may develop due to travel in cramped spaces and/or due to poor posture when working in a seated position.
SUMMARY OF THE INVENTIONThe invention is a portable travel footrest with which a traveler may exercise while seated in a plane or other cramped conditions and avoid uncomfortable and dangerous lower leg conditions.
An object of this invention is to provide a device that enables airline passengers to exercise the legs while seated.
Another invention is to make such a device collapsible so that it can be carried and stored conveniently.
These and other objects of the invention are satisfied by the collapsible footrest described below.
BRIEF DESCRIPTION OF THE DRAWINGSThe invention is described in detail below with reference to the following figures, throughout which similar reference characters denote corresponding features consistently, wherein:
A footrest embodying the invention includes a platform mounted on a nearer pair of non-resilient legs and a longer farther pair of resilient legs.
The legs 110, 115 shown in
The legs 110, 115 are sized and configured to position the platform above ground level at an incline or angle so that the front edge 130 is nearer to the user's feet and to the ground and the back edge 135 is farther to the user's feet and higher than the front edge 130. Thus, when resting on the platform, the heel or heels of the user's foot or feet will be closer to the ground and the toes will be higher than the heel(s) in a naturally inclined position when the user's legs are extended outwardly and away from the body.
When attached, the legs 110 may define a 90° angle, or other angle, relative to a surface on which the footrest is disposed. Consequently, the legs 110 are not square to, but define a predetermined angle 140 relative to the platform 105.
The legs 115 define a 90° angle, or other angle, relative to the platform 105. Consequently, the legs 115 are not square to, but define a predetermined angle 145 relative to a surface on which the footrest is disposed.
The lengths of the legs 110, 115 are adjustable. Adjustment may be achieved through incorporating telescoping, threading or other mechanisms (not shown).
Each leg 110, 115 has anti-skid material for contacting a supporting surface or floor. The anti-skid material may be selected from rubber, felt, plastic, metal, wood or other materials that would prevent the footrest 100 from skidding on a surface on which it is placed.
The legs 115 each include a spring mechanism 117 (

The footrest 100, when fully assembled and operational, fits under most airline seats in front of the passenger using the footrest. When folded for portability, the footrest 100 fits into most travel bags, hand bags, computer cases or in a specially designed carrying case or bag.

Common design features in the embodiments described herein relate to: (1) compactness, for making the device truly portable through compacting the entire structure to some fraction of its operational size; and (2) the use of the device for exercise, involving built-in resilient mechanisms.
The invention provides for a carry case or carry bag for receiving and transporting any collapsed footrest embodiment described herein.
Claims
1. A collapsible leg-exercising footrest, the footrest comprising,
- a platform, and
- a plurality of legs for supporting the platform,
- at least some of said legs comprising a compressible element so that when one presses on the platform with one's feet the legs change in length and provide resistance against the force applied with the feet,
- said legs having a deployed position and a collapsed position within or against the platform.
2. The invention of claim 1, wherein the compressible element is a spring and the leg has two telescoping portions, one at either end of the spring.
3. The invention of claim 1, wherein the compressible element is a pneumatic chamber and the leg has two telescoping portions, one at either end of the pneumatic chamber.
4. The invention of claim 1, wherein at least some of the legs can be detached from the platform and stored within cavities in the platform.
5. The invention of claim 1, wherein at least some of the legs have a hinged connection with the platform and can be folded flush against the platform.
6. The invention of claim 1, wherein the platform comprises plural pieces.
7. The invention of claim 6, wherein the plural pieces are interconnected by tongue and groove connections.
8. The invention of claim 7, further comprising means for locking the plural pieces in their assembled condition.
9. The invention of claim 6, wherein the plural pieces are connected by hinges.
10. The invention of claim 1, wherein at least some of the legs have a hinged connection to the platform and further comprising, a brace for locking the hinged legs in their deployed position.
