the inventive device described in the instant application is a leg rest with collapsible capabilities . it is made with light weight metal and thin airy cloth to rest the user &# 39 ; s legs on . it can be used by the user anywhere because of the devices collapsibility and portability it is an efficient and convenient way to transport a leg rest . the mechanism for the invention is a portable leg rest that folds open by with a canvas like material attached to the collapsible legs and has a center leg for stability . the collapsible leg rest is designed to portable and a foldable way for users to have access to a leg rest in any environment this device can be used by any user that had pain in their extremities or doesn &# 39 ; t . in one preferred embodiment of “ collapsible leg rest ” of the present application will be either a larger or smaller leg rest with extendable capabilities the premise is to provide invention that is a leg rest for users who have pain in their extremities and need a leg rest to be readily available to alleviate the pain . the leg rest is portable thanks to its collapsible legs like that resemble the mechanism in an umbrella . this device will allow for the convenience of a leg rest to be used within any environment . users will have a convenient and efficient way of having a leg rest available in any instance . “ collapsible leg rest ” provides a quick method to allow the user to alleviate any pain within their extremities by allowing them to raise their legs higher than their bodies . a footstool ( foot stool , footrest , foot rest ) is a piece of furniture or a support used to elevate the foot . there are two main types of footstool , which can be loosely categorized into those designed for comfort and those designed for function . this type of footstool is used to provide comfort to a person seated , for example , in a chair or sofa . it is typically a short , wide , four - legged stool with a padded top , upholstered in a fabric or animal hide , such as leather . this type of footstool is also a type of ottoman . it allows the seated person to rest his feet upon it , supporting the legs at a mostly horizontal level , thus giving rise to use of the term footrest , for this item . and high quality footstool could adjust different height as personal will . an umbrella or parasol is a canopy designed to protect against rain or sunlight . the word parasol usually refers to an item designed to protect from the sun ; umbrella refers to a device more suited to protect from rain . often the difference is the material ; some parasols are not waterproof . umbrellas and parasols are primarily hand - held portable devices designed to shield an individual from sun or rain , and are sized for personal use . today , larger parasols are often used as fixed or semi - fixed devices , used with patio tables or other outdoor furniture , or as points of shade on a sunny beach . the collapsible ( or folding ) umbrella may have first been used in china and had sliding levers similar to those in use today . a cement is a binder , a substance that sets and hardens as the cement dries and also reacts with carbon dioxide in the air dependently , and can bind other materials together . the word “ cement ” traces to the romans , who used the term opus caementicium to describe masonry resembling modern concrete that was made from crushed rock with burnt lime as binder . the volcanic ash and pulverized brick additives that were added to the burnt lime to obtain a hydraulic binder were later referred to as cementum , cimentum , cäment , and cement . cements used in construction can be characterized as being either hydraulic or non - hydraulic , depending upon the ability of the cement to be used in the presence of water ( see hydraulic and non - hydraulic lime plaster ). non - hydraulic cement will not set in wet conditions or underwater , and is attacked by some aggressive chemicals after setting . canvas is an extremely heavy - duty plain - woven fabric used for making sails , tents , marquees , backpacks , and other items for which sturdiness is required . it is also popularly used by artists as a painting surface , typically stretched across a wooden frame . it is also used in such fashion objects as handbags , electronic device cases and shoes . aluminium ( or aluminum ; see spelling differences ) is a chemical element in the boron group with symbol al and atomic number 13 . it is a silvery white , soft , ductile metal . aluminium is the third most abundant element ( after oxygen and silicon ), and the most abundant metal in the earth &# 39 ; s crust . it makes up about 8 % by weight of the earth &# 39 ; s solid surface . aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments . instead , it is found combined in over 270 different minerals . the chief ore of aluminium is bauxite . aluminium is remarkable for the metal &# 39 ; s low density and for its ability to resist corrosion due to the phenomenon of passivation . structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials . the most useful compounds of aluminium , at least on a weight basis , are the oxides and sulfates . despite its prevalence in the environment , no known form of life uses aluminium salts metabolically . in keeping with its pervasiveness , aluminium is well tolerated by plants and animals . owing to their prevalence , potential beneficial ( or otherwise ) biological roles of aluminium compounds are of continuing interest . in one of its preferred embodiments the inventive device of the present application embodies a portable leg rest comprises : the canvas rest ( 1 ) that is stably held by the center leg ( 2 ) and is stretched over a plurality of foldable legs ( 3 ) that is held by a plurality of fastening means ( 4 ) such as hinges , or rubber stoppers . the foldable legs ( 3 ) are connected to a plurality of collapsing arms ( 7 ) by the metal hinge ( 5 ) and stabilized by the metal bar ( 6 ). the leg rest device is tied together with elastic wrap ( 8 ). the canvas rest ( 1 ) can be changed or washed thanks to the removable plastic cap ( 9 ). in a separate preferred embodiment the portable leg rest of the present application comprises a band , such as a rubber band to keep it tight when it is in its collapsed configuration . both said center leg , and said plurality of foldable legs are composed by a plurality of concentric tubes . said tubes may be held in their extended configuration by a pin . in a separate preferred embodiment of the portable leg rest of the present application a plurality of internal springs are used to keep the central leg and said plurality of legs collapsed . as to a further discussion of the manner of usage and operation of the present invention , the same should be apparent from the above description . accordingly , no further discussion relating to the manner of usage and operation will be provided . with respect to the above description then , it is to be realized that the optimum dimensional relationships for the parts of the invention , to include variations in size , materials , shape , form , function and manner of operation , assembly and use , are deemed readily apparent and obvious to one skilled in the art , and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention . therefore , the foregoing is considered as illustrative only of the principles of the invention . further , since numerous modifications and changes will readily occur to those skilled in the art , it is not desired to limit the invention to the exact construction and operation shown and described , and accordingly , all suitable modifications and equivalents may be resorted to , falling within the scope of the invention .
the inventive device described in the instant application is a leg rest with collapsible capabilities . it is made with light weight metal and thin airy cloth to rest the user &# 39 ; s legs on . it can be used by the user anywhere because of the devices collapsibility and portability it is an efficient and convenient way to transport a leg rest . it is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure .
